简介：AbstractMarking the end of the five-year programme initiated by the Chinese Government to lift more than 70 million people out of poverty, the year 2020 is a milestone. Poverty alleviation has moved strongly forward in China and the major health indicators are now better than the average of all middle- and high-income countries. However, the dual burden of infectious and chronic diseases remains a challenge with respect to achieving the health target in the United Nations 2030 Agenda for sustainable development goals (SDGs). In 2015, about 44% of the poor population in China were impoverished by illness but already in 2018, multi-sectoral actions delivered by the Health-related Poverty Alleviation programme had reduced the number almost by half. In the past three years 15 million poor people (98% of the poor population) with infectious and chronic diseases had been treated and taken care of thanks to financial support through multiple health insurance schemes and other governmental subsidies. This article discusses the lessons learnt with regard to health-related poverty alleviation in China with special reference to those still remaining impoverished by illness. Consolidation of the achievements reached and provision of basic needs to those still disadvantaged and in poor health will require a major improvement of accessibility to, and affordability of, health services. The next step towards enhanced productivity and better living conditions will involve upgrading of the capacity of health professionals in the poor regions, promotion of coherent efforts in health-related poverty alleviation and rural revitalization measures. As an additional measure, data monitoring and research on health poverty alleviation should be strengthened as they are essential to generate the evidence and knowledge needed to support the move in the direction envisioned by the SDGs, and the new Healthy China 2030 programme.

简介：AbstractBackground:Pulmonary deportation of hydatidiform mole is an exceedingly rare entity. The underlying mechanisms and proper management strategies remain unclear based on sporadic case reports over the past six decades. This study aimed to investigate the clinical features and rational treatment of patients with benign molar pregnancies with pulmonary deportation based on our experience.Methods:Medical records of 20 cases of hydatidiform mole with pulmonary deportation were retrospectively reviewed at Peking Union Medical College Hospital from November 2006 to May 2019. The detailed information of all patients was recorded and analyzed. Patients were divided into different groups according to their characteristics and Mann-Whitney U test was used to compare the duration to achieve a normal β-human chorionic gonadotrophin (β-hCG) level after the first evacuation among groups.Results:Initial pulmonary computed tomography scans showed suspected bilateral, left and right chest deportation of hydatidiform mole in 12, four, and four patients, respectively, with the maximum nodular diameter ranging from 0.6 to 1.2 cm. Ten patients achieved lesion resolution while the remaining ten patients achieved decreases in the size of their pulmonary lesions. The median duration to achieve a normal β-hCG level after the first evacuation was 15.5 (13.0, 21.9) weeks. There was no significant difference in the duration to achieve a normal β-hCG level after the first evacuation between two groups based on age (≥40 years vs. < 40 years: 15.8 [12.2, 21.5] weeks vs. 15.5 [12.9, 23.0] weeks, Z = 0.094, P = 0.925), type of antecedent mole (partial mole vs. complete mole: 15.2 [12.5, 27.4] weeks vs. 15.9 [12.9, 21.5] weeks, Z = 0.165, P = 0.869), distribution of pulmonary nodules (bilateral lungs vs. unilateral lung: 15.2 [12.8, 22.5] weeks vs. 15.9 [13.2, 22.2] weeks, Z = 0.386, P = 0.700), maximum size of pulmonary nodules (>0.5 cm vs. ≤0.5 cm: 13.0 [11.3, 17.2] weeks vs. 16.0 [14.5, 23.8] weeks, Z = 1.815, P = 0.070), and number of uterine evacuations (once vs. twice or three times: 15.0 [13.0, 16.3] weeks vs. 16.0 [12.8, 23.9] weeks, Z = 0.832, P = 0.405). The post-molar cohort was followed up for 17 to 139 months, and no gestational trophoblastic neoplasia was observed.Conclusions:No surgeries other than uterine evacuation and no chemotherapy regimens are recommended for such patients if they achieve satisfactory decreases in the level of hCG and gradual decrease or disappearance of pulmonary deportation nodules. Patients should be informed about the necessity of long-term follow-up. More collaborative international studies on this exceedingly rare condition may guide decisions regarding optimal management strategies.

简介：AbstractBackground:Worldwide, the volume and availability of digestive endoscopy have undergone dramatic development in recent years, with increasing attention on quality assurance. We investigated the utilization and quality of digestive endoscopy in China from 2015 to 2019 and developed a quantitative quality evaluation tool for medical institutions.Methods:We invited all tertiary/secondary hospitals in Chinese mainland to participate in the survey annually. The questionnaires included the personnel, annual volume, and quality indicators of endoscopy. An endoscopy quality index (EQI) was developed based on recorded quality indicators using principal component analysis to determine the relative weight.Results:From 2015 to 2019, 806, 1412, 2644, 2468, and 2541 hospitals were respectively enrolled in this study. The average annual volume of endoscopy increased from 12,445 to 16,206 (1.30-fold) and from 2938 to 4255 (1.45-fold) in tertiary and secondary hospitals, respectively. The most obvious growth was observed in diagnostic colonoscopy (1.44-fold for all hospitals after standardization). The proportion of early cancer among all esophageal and gastric cancers during diagnostic esophagogastroduodenoscopy increased from 12.3% (55,210/448,861) to 17.7% (85,429/482,647) and from 11.4% (69,411/608,866) to 16.9% (107,192/634,235), respectively. The adenoma detection rate of diagnostic colonoscopy increased from 14.9% (2,118,123/14,215,592) to 19.3% (3,943,203/20,431,104). The EQI model included 12 quality indicators, incorporating 64.9% (7.792/12) of the total variance into one comprehensive index. According to the EQI measurements, the quality of endoscopy was higher in tertiary hospitals and hospitals in developed areas with higher volume or more endoscopists than that in other hospitals.Conclusions:Digestive endoscopy in China has developed considerably in recent years in terms of both volume and quality. The EQI is a promising tool to quantify the quality of endoscopy at different hospitals.

简介：AbstractImportance:Cancer is the main cause of death by disease in children. Children experience the highest incidence of cancer in the first year of life. However, there is no comprehensive registration system for children with tumors in China.Objective:To summarize the diagnosis and treatment of infant cancer and analyze the status of standardized diagnosis and management among several treatment centers in Beijing, China, thereby providing evidence to guide further clinical research.Methods:From January 1, 2010 to December 31, 2019, patients with newly diagnosed infantile malignant solid tumors were admitted to six large tertiary pediatric solid tumor diagnosis and treatment centers in Beijing. The epidemiology, clinical features, and therapeutic effects of tumors in these patients were analyzed retrospectively. All patients were followed up until March 31, 2020.Results:In total, 938 patients were enrolled in this study. There were 530 boys (56.5%) and 408 girls (43.5%); the median age was 6.0 months (range, 0-12.0 months). The three most common tumors were retinoblastoma in 366 patients (39.0%), neuroblastoma in 266 patients (28.4%), hepatoblastoma in 133 patients (14.2%), and central nervous system tumors in 52 patients (5.5%). The estimated 5-year overall survival rate was 81.3% ± 1.8%, and the 5-year event-free survival rate was 71.8% ± 2.9%. The 5-year overall survival rates of non-rhabdomyosarcoma soft tissue sarcoma, neuroblastoma, and retinoblastoma were 100%, 88% ± 2.2%, and 86.9% ±2.1%, respectively. The 5-year event-free survival rates were 81.1% ± 2.7% for neuroblastoma, 81.6% ± 9.8% for non-rhabdomyosarcoma soft tissue sarcoma, and 72.7% ± 14.1% for extracranial malignant germ cell tumors.Interpretation:The three most common infantile malignant solid tumors were retinoblastoma, neuroblastoma, and hepatoblastoma. Multidisciplinary combined diagnosis and treatment is needed for infantile tumors.

简介：AbstractBackground:Hypertension is associated with stroke-related mortality. However, the long-term association of blood pressure (BP) and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown. The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations.Methods:This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020. COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) categories and BP changes from 1976 to 1994. The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths. E value was calculated in the sensitivity analysis.Results:Among 1696 participants, the average age was 44.38 ± 6.10 years, and 1124 were men (66.3%). After a 45-year follow-up, a total of 201 (11.9%) stroke-related deaths occurred. After the adjustment, the COX proportional hazard model showed that among the participants with SBP ≥ 160 mmHg or DBP ≥ 100 mmHg in 1976, the risk of stroke-related death increased by 217.5% (hazard ratio [HR] = 3.175, 95% confidence interval [CI]: 2.297-4.388), and the adjusted HRs were higher in male participants. Among the participants with hypertension in 1976 and 1994, the risk of stroke-related death increased by 110.4% (HR= 2.104, 95% CI: 1.632-2.713), and the adjusted HRs of the BP changes were higher in male participants. Body mass index (BMI) significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender.Conclusions:In a 45-year follow-up, high BP and persistent hypertension are associated with stroke-related death, and these associations were even more pronounced in male participants. The paths of association are mediated by BMI and moderated by gender.

简介：AbstractBackground:Mastectomy techniques have been extended to nipple-sparing mastectomy (NSM). This study aimed to assess the actual application of NSM in China and identify the factors influencing postoperative complications.Methods:The clinical data of 615 patients (641 surgeries) undergoing NSM from January 1st, 2018 to December 31st, 2018 at 28 centers nationwide were retrospectively analyzed to obtain the rate of NSM and investigate factors related to NSM surgery.Results:The proportion of NSM surgery performed in this study was 2.67% (17/641). Malignant breast tumors accounted for the majority of NSM surgery (559/641, 87.2%). A total of 475 (77.3%) patients underwent NSM combined with reconstructive surgery. The rate of reconstruction decreased with age in our study, and implants were the most common option (344/641, 53.7%) in reconstruction. Radial incision was the most selected method regardless of reconstruction. However, for those who underwent reconstruction surgery, 18.4% (85/462) of cases also chose curvilinear incision, while in the simple NSM surgery group, more patients chose circumareolar incision (26/136, 19.1%). The tumor-to-nipple distance (TND) influenced postoperative complications (P = 0.004). There were no relationships between postoperative complications and tumor size, tumor location, histologic grade, molecular subtype, nipple discharge, and axillary lymph nodes.Conclusions:NSM surgery is feasible and only TND influenced postoperative complications of NSM surgery. But the proportion of NSM surgery performed is still low in nationwide centers of China. The selection criteria for appropriate surgical methods are important for NSM in clinical practice. To optimize clinical applications of NSM, further multicenter prospective randomized controlled studies are needed.Trial Registration:ChiCTR.org.cn, ChiCTR1900027423; http://www.chictr.org.cn/showprojen.aspx?proj=38739

简介：AbstractBackground:Cerebrovascular disease has become the leading cause of death in China. The purpose of this article is to analyze China's contribution to the interventional treatment of cerebrovascular diseases.Methods:Bibliometric analysis was used for evaluating the quantity, quality, research hotspots, and cooperation network of publications regarding interventional treatment of cerebrovascular diseases from China. These articles were searched from the database of Web of Science Core Collection. The authors, publication years, citation times, regions, and source journals of retrieved articles were recorded. Network analysis and visualization were performed on Citespace5.6.Results:From 1991 to 2019, a total of 5052 articles regarding cerebrovascular intervention were contributed by Chinese researchers. The number of publications from China grew fastest annually in the latest 5 years among countries. These publications were cited 61,216 times, with 12.12 average citations per item. The h-index was 82. Affiliated hospitals of Capital Medical University contributed most articles. Cerebral ischemia and intracranial aneurysm were the most popular keywords over the three decades. The timeline view of keywords indicated that cerebral ischemia always was a hot spot. Stent techniques were the main treatment tools and still had a strong developing trend. Neural regeneration and neuroprotection were the hot topics of basic researches related to cerebrovascular intervention.Conclusions:The number of researches grows rapidly in China over the decades, but the quality still needs further improvement. The increasing contributions of Chinese researchers to the global knowledge system of cerebrovascular intervention are promising.

简介：AbstractBackground:The Chinese appropriate use criteria (AUC) for coronary revascularization was released in 2016 to improve the use of coronary revascularization. This study aimed to evaluate the association between the appropriateness of coronary revascularization based on the Chinese AUC and 1-year outcomes in stable coronary artery disease (CAD) patients.Methods:We conducted a prospective, multi-center cohort study of stable CAD patients with coronary lesion stenosis ≥50%. After the classification of appropriateness based on Chinese AUC, patients were categorized into the coronary revascularization group or the medical therapy group based on treatment received. The primary outcome was a composite of death, myocardial infarction, stroke, repeated revascularization, and ischemic symptoms with hospital admission.Results:From August 2016 to August 2017, 6085 patients were consecutively enrolled. Coronary revascularization was associated with a lower adjusted hazard of 1-year major adverse cardiovascular and cerebrovascular events (MACCEs; hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.45–0.86; P = 0.004) than medical therapy in patients with appropriate indications (n = 1617). No significant benefit in 1-year MACCEs was found after revascularization compared to after medical therapy in patients with uncertain indications (n = 2658, HR: 0.81; 95% CI: 0.52–1.25; P = 0.338) and inappropriate indications (n = 1810, HR: 0.80; 95% CI: 0.51–1.23; P = 0.308).Conclusions:In patients with appropriate indications according to Chinese AUC, coronary revascularization was associated with significantly lower risk of MACCEs at 1 year. No benefit was found in coronary revascularization in patients with inappropriate indications. Our findings provide evidence for using Chinese AUC to guide clinical decision-making.Clinical trial registration:NCT02880605. https://www.clinicaltrials.gov.

简介：AbstractBackground:Numerous studies have focused on lymphoma among patients infected with human immunodeficiency virus (HIV). However, little is known about the treatment options and survival rate of lymphoma in the Chinese people living with HIV (PLHIV). Our study aimed to investigate the prognosis and compare outcome of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab(R-CHOP) as front line therapy for PLHIV with diffuse large B-cell lymphoma (DLBCL) receiving modern combined antiretroviral therapy (cART).Methods:A retrospective analysis evaluating PLHIV with DLBCL was performed in Shanghai Public Health Clinical Center from July 2012 to September 2019. The demographic and clinical data were collected, and overall survival (OS) and progression-free survival (PFS) analyses of patients receiving R-CHOP or DA-EPOCH-R therapy were performed by Kaplan-Meier analysis. Additionally, a Cox multiple regression model was constructed to identify related factors for OS.Results:A total of 54 eligible patients were included in the final analysis with a median follow-up of 14 months (interquartile range [IQR]: 8-29 months). The proportion of high international prognostic index (IPI) patients was much larger in the DA-EPOCH-R group (n = 29) than that in the R-CHOP group (n = 25). The CD4 cell counts and HIV RNA levels were not significantly different between the two groups. The 2-year OS for all patients was 73%. However, OS was not significantly different between the two groups, with a 2-year OS rate of 78% for the DA-EPOCH-R group and 66% for the R-CHOP group. Only an IPI greater than 3 was associated with a decrease in OS, with a hazard ratio of 5.0. The occurrence of grade 3 and 4 adverse events of chemotherapy was not significantly different between the two groups.Conclusions:Outcomes of R-CHOP therapy do not differ from those of DA-EPOCH-R therapy. No HIV-related factors were found to be associated with the OS of PLHIV in the modern cART era.
