ObjectiveTo investigate the prevalence rate of chronic non-communicable diseases （NCDs） and the association with quality of life in middle-aged and elderly patients with HIV/AIDS. MethodsThis cross-sectional study surveyed 432 patients with HIV/AIDS （aged≥45 years） in the Infectious Disease Center in Guangzhou Eighth People’s Hospital of Guangzhou Medical University， and 366 participants were included in the analysis after quality control. A questionnaire and the EuroQol 5-Dimensional 3-level version （EQ-5D-3L） were used to investigate NCDs and quality of life and Tobit regression model was used to estimate the association between chronic diseases and quality of life. ResultsAmong the 366 participants， 29（7.9%） had cardiovascular disease， 45（12.3%） had hypertension， 122（33.3%） had hyperglycemia， 151（41.3%）had hyperlipidemia，7（1.9%） had cancer， 17 （4.6%） had chronic kidney disease， 38 （10.4%） had chronic liver disease， 21（5.7%） had musculoskeletal disorders， and 253（69.1%） suffered from at least one type of chronic diseases. The median （lower and upper quartiles） of EQ-5D utility index was 1.000（0.964~1.000）. Multivariate Tobit regression results of the total population showed that cancer ［b_a=-0.08，95%CI （-0.15，-0.01），P=0.036］， chronic kidney disease ［b_a=-0.07， 95%CI （-0.12，-0.02），P=0.006］， musculoskeletal disease ［b_a=-0.09， 95%CI （-0.13， -0.05），P<0.001］， and ≥3 types of chronic diseases［b_a=-0.05， 95%CI（-0.08，-0.01），P=0.013］ were negatively correlated with EQ-5D utility index. The stratified analysis results of different CD4+T cell levels showed that hypertension ［b_a=-0.07， 95%CI （-0.12， -0.02）， P=0.007］， chronic kidney disease ［b_a=-0.10，95%CI （-0.18，-0.03）， P=0.006］， musculoskeletal disease ［b_a=-0.15， 95%CI （-0.22，-0.07）， P<0.001］ and ≥3 types of chronic diseases ［b_a=-0.09， 95%CI （-0.09， -0.01）， P<0.001］ were negatively correlated with EQ-5D utility index in the group with CD4≤500 （cells/μL）， whereas cancer［b_a=-0.11， 95%CI （-0.20，-0.01）， P=0.031］ was negatively correlated with EQ-5D utility index in the group with CD4＞500（cells/μL）. ConclusionsThe prevalence rate of chronic non-communicable diseases in middle-aged and elderly patients with HIV/AIDS is relatively high. The classification of NCDs such as cancer or chronic kidney disease or other chronic diseases and the numbers of NCDs categories are negatively correlated with quality of life. However，this association varies among patients with HIV/AIDS of different CD4+T cell levels. It is suggested that we should try to prevent and identify NCDs at an early stage， strengthen linkages and integration of health services for AIDS and chronic NCDs， and jointly manage and control AIDS with chronic diseases to improve the quality of life among people living with HIV/AIDS.

Objective To establish primary and simian virus 40(SV40)T antigen transformed human vascular en-dothelial cell models,and provide available resources for endothelial research.Methods Human umbilical vein endothelial cells(HUVEC),human umbilical artery endothelial cells(HUAEC),great saphenous vein endothelial cells(GSVEC)and endothelial cells form endometrium and liver tissue were isolated and cultured respectively.Then,the primary endothelial cells were transformed by lentivirus containing SV40 big T and small T antigens,and continuously subcultured in vitro.The expression of CD31 was detected by flow cytometry,species identification-and mycoplasma detection by PCR,and cell identity was identified by STR detection.The transformed ECs were checked for HLA types.Some of them were tested for RNA expression profile and infected by Cas9 lentivirus to es-tablish stable clones.Results Totally 187 cell lines of transformed HUVEC,1 of transformed HUAEC,5 of trans-formed GSVEC,1 of transformed endothelial cells from endometrium and 1 of transformed endothelial cells from liv-er tissue,and 9 monoclonal HUVEC cell lines stably expressing Cas9 protein were established.All the transformed umbilical endothelial cells were CD31 positive ranging from 20%-90%for 20 cases,while for the rest 168 cases the positive rate was more than 90%.RNA expression revealed stable activation of cell proliferation(cell cycle and DNA synthesis).Their species were identified as human origin.The STR results were consistent with those of the primary culture and unique,and there was no mycoplasma contamination.All these cells could be obtained with the sharing services of National Science and Technology Infrastructure,the National Biomedical Cell-line Resource cen-ters(NSTI-BMCR).Conclusions A series of primary and SV40 T antigen transformed human vascular endothelial cell models have been established,which provide a tool for the study of cardiovascular diseases,inflammation,tumors and immune-related diseases.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Hepatocellular carcinoma(HCC) is one of the most common malignancies of the digestive system,which is prone to be associated with microvascular or macrovascular invasion. Among them,HCC with inferior vena cava tumor thrombus(IVCTT) or right atrium tumor thrombus(RATT) is rare and has a poor prognosis. However,surgical treatment of HCC with IVCTT and (or) RATT is rarely reported and summarized. The review described the classification of HCC tumor thrombus with IVCTT and (or) RATT, summarized the progress of surgical approaches and surgical operations,and introduced a case of thrombectomy after pushing from the outer surface of the atrium,rendering the RATT to the inferior vena cava under non-cardiopulmonary bypass. The review also proposed the prospective treatments for HCC with IVCTT or RATT,providing clinical guidance to hepatobiliary surgeons.

【Objective】 To provide reference for fine management of blood donors by classifying and analyzing different types of blood donors from domestic blood stations. 【Methods】 The resident population of 15 regions in China from 2016 to 2019 were taken as the research object, among which the blood donors were divided into three categories: age-eligible citizens, registered donors and donated donors. The average value and proportion of the three categories were calculated and statistically analyzed. 【Results】 The resident population of the 15 regions varied greatly. The mean 95% CI of the proportion of age-eligible citizens to resident population from 2016 to 2019 was (60.16%, 67.84%); registered donors to age-eligible citizens and resident population was (2.21%, 2.86%) and (1.41%, 1.79%), respectively; donated donors to registered donors, age-eligible citizens and resident population was (84.63%, 91.68%), (1.93%, 2.55%) and(1.23%, 1.59%), respectively. 【Conclusion】 There were differences in the number and proportion of different types of blood donors in different regions. The fine management of blood donors can help blood stations carry out more effective recruitment and retention strategies.

Objective:To investigate the effect of complex decongestive therapy(CDT) on elephantiasis and skin texture improvement.Methods:The clinical data of patients with elephantiasis of lower limbs who were admitted to the Department of Plastic Surgery, Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2016 to December 2018 were retrospectively analyzed. The patients with elephantiasis of different causes were treated with CDT for 1 course (4 weeks). The skin texture parameters (skin water content, transepidermal water loss, skin fibrosis), limb circumference and segmental edema were measured before and after treatment and analyzed by paired t test. Pearson correlation analysis was used to detect the correlation between segmental edema and skin texture parameters before and after treatment. The subjective feelings of patients were recorded during follow-up. A self-designed online questionnaire was used to follow up the patient’s disease control status, including the limb circumferences, changes in quality of life (life, work, social and emotion), the adaptability to bandages and elastic socks. Data were classified and analysed as excellent, good, medium and poor.Results:A total of 20 patients were included, including 16 females and 4 males. The average age was 50.45 years (ranged 9-70 years). 5 cases were primary lymphedema and 15 cases were secondary lymphedema. The duration of the disease ranged from 2 years to 27 years, with an average of 8.4 years. After 1 course of treatment, the skin texture was significantly improved. The skin water content decreased from 55.6%±7.4% before treatment to 42.1%±7.4% after treatment ( P< 0.001). The transepidermal water loss decreased from (14.981±5.699) g·m -2·h -1 before treatment to (9.312±2.590) g·m -2·h -1 after treatment. The skin fibrosis decreased from (0.087±0.042) N before treatment to (0.065±0.033) N after treatment ( P<0.001). The circumference of the affected limb decreased from (11.09±3.14) cm before treatment to (4.82±2.83)cm after treatment ( P<0.001). The segmental edema decreased from (4.00±2.14)L before treatment to (1.21±0.78) L after treatment. Segmental edema was positively correlated with skin water content, transepidermal water loss, and skin fibrosis ( r=0.447, r=0.429, r=0.751, P<0.05). The patients were followed up for 6 months after treatment. The circumference control was excellent in 13 cases, good in 5 cases and moderate in 2 cases. The quality-of-life changes were excellent in 16 cases, good in 3 cases, medium in 1 case. The adaptability of elastic material was excellent in 9 cases, good in 8 cases, medium in 2 cases and poor in 1 case. Conclusions:CDT can reduce subcutaneous edema, effectively reduce limb volume, decrease skin fibrosis, improve skin barrier function, improve skin texture, restore the appearance of the limb and improve patients’ quality of life.
