Objective:To investigate the interaction of risk factors for diabetic retinopathy (DR) occurrence.Methods:A cross-sectional study was performed.A total of 6 783 diabetic patients with complete survey data from 2005 to 2018 in the National Health and Nutrition Survey database were enrolled, among which 4 426 patients were included according to inclusion criteria and were divided into non-DR diabetes group of 3 491 cases and DR group of 935 cases.The related risk factors were collected, including age, gender, race, residential status, education, annual household income, body mass index (BMI), fasting glucose, glycosylated hemoglobin, duration of diabetes, family history of diabetes, comorbidities, smoke, alcohol use, sleep, physical activity.Patient Health Questionnaire (PHQ-9) was used to assess the psychological status.After the categorization of all variables, risk factors of DR were analyzed by logistic regression, and the interaction between factors was further analyzed.Results:Multivariate analysis showed that female[odds ratio ( OR)=1.33, 95% confidence interval ( CI): 1.02-1.72], duration of diabetes ≥10 years ( OR=1.03, 95% CI: 1.02-1.04), insulin therapy ( OR=2.38, 95% CI: 1.87-3.05), urinary albumin creatinine ratio (UACR) ≥30 mg/g ( OR=1.55, 95% CI: 1.22-1.96) and depression ( OR=1.44, 95% CI: 1.13-1.83) were risk factors for DR, and BMI≤28 kg/m 2 ( OR=0.70, 95% CI: 0.55-0.89) was a protective factor for DR.Furthermore, interaction analysis revealed additive interaction between UACR ≥30 mg/g and insulin therapy [relative excess risk due to interaction ( RERI)=2.46, 95% CI: 0.84-4.09, attributable proportion due to interaction ( AP)=0.44, 95% CI: 0.26-0.63, synergy index ( S)=2.16, 95% CI: 1.37-3.41).The UACR ≥30 mg/g and longer diabetic duration ≥10 years had both multiplicative ( OR=1.67, 95% CI: 1.00-2.76) and additive interactions ( RERI=2.02, 95% CI: 0.79-3.25, AP=0.47, 95% CI: 0.27-0.66, S=2.53, 95% CI: 1.37-4.68). Conclusions:Patients with diabetes treated with insulin, with a duration of diabetes ≥10 years and accompanied by UACR ≥30 mg/g are at higher risk of developing DR than those with a single risk factor.

Objective:To investigate the prevalence of and risk factors associated with Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) and high-risk human papillomavirus (HPV) coinfections among patients with newly diagnosed syphilis at a hospital in Nanjing. Methods:A cross-sectional study was conducted on patients with newly diagnosed syphilis at the STD Clinic, Hospital of Dermatology, Chinese Academy of Medical Sciences in Nanjing, China from May 2023 to April 2024. Urethral, cervical or rectal swabs were collected according to the gender and types of sexual behavior of the patients. Screening tests for CT, NG and HPV infections were then performed by nucleic acid amplification testing. High-risk HPV testing was performed only in female patients. Univariate analysis was carried out to investigate risk factors associated with CT infection. The chi-square test, chi-square test with continuity correction, or Fisher's exact test was chosen based on the sample size and expected values.Results:A total of 111 newly diagnosed syphilis patients with test specimens were collected, including 71 males (64%) and 40 females (36%), and their ages ranged from 16 to 87 years; there were 82 patients with early syphilis and 29 with late latent syphilis; the number of sexual partners in the past 3 months ranged from 0 to 3. Among the 60 male patients with early syphilis, 1 (1.7%) was co-infected with NG, and 12 (20%) with CT; among the 16 men who have sex with men, 7 (43.8%) were co-infected with CT, while 5 (11.4%) of the 44 heterosexual patients were co-infected with CT, showing a significant difference in CT infection rates between the two groups ( χ2 = 5.80, P = 0.016). Among the 22 female patients with early syphilis, 1 (4.5%) was co-infected with NG, and 8 (36.4%) with CT; among the 12 female patients aged < 25 years, 8 (66.7%) were infected with CT, while none of the 7 patients aged 25-44 years or the 3 patients aged ≥ 45 years were infected with CT, showing a significant difference in CT infection rates among the 3 age groups ( P = 0.005) ; among the 16 female patients with 1 sexual partner in the past 3 months, 3 were infected with CT, while 5 were infected with CT in the 6 female patients with 2-3 sexual partners in the past 3 months, with a significant difference in CT infection rates between the two groups ( P = 0.011). Out of the 40 female patients with syphilis, 16 (40%) were co-infected with high-risk HPV; the HPV infection rates did not differ among different age groups (age groups of < 25 years, 25-44 years, ≥ 45 years: 8/14, 2/9, 6/17, respectively; P = 0.265) . Conclusion:The CT infection rate was relatively high in patients with newly diagnosed early syphilis, and a relatively high infection rate of high-risk HPV was observed in female patients with syphilis aged < 25 years.

Objective:To determine the prevalence and associates of hyperuricemia (HUA) among the middle- and older-aged population of the island and mountainous areas in Taizhou City of Zhejiang Province.Methods:A cross-sectional study was conducted on individuals aged 45 and above in the island and mountainous area of Taizhou City. The study included questionnaires, physical examinations, and laboratory tests. Data were primarily collected on sociodemographic characteristics, chronic disease history, lifestyle factors, waist circumference, blood pressure, and serum uric acid levels. The association between hyperuricemia and these factors was analyzed by logistic regression.Results:A total of 971 individuals were included in the study, comprising 468 from island and 503 from mountainous area. The prevalence of hyperuricemia was 17.9%, with a significantly higher prevalence in the island area (25.6%) compared to the mountainous area (10.7%). Stratified by gender and age, differences in the prevalence of hyperuricemia between island and mountainous areas were observed in males aged 55 to 64, females aged 45 to 54, 55 to 64, 75 and above (all P<0.05). Multiple logistic regression analysis showed that high intake of sea food (>3 times/week) was positively associated with hyperuricemia ( OR=2.10, 95% CI:1.33-3.34). Furthermore, separate regionally stratified logistic regression analyses showed that in the island area, male gender ( OR=3.15, 95% CI:1.78-5.66), central obesity ( OR=2.38, 95% CI:1.46-3.93), and hypertriglyceridemia ( OR=2.00, 95% CI:1.22-3.30) were positively correlated with hyperuricemia (all P<0.05). In the mountainous area, the age group of 65 and above ( OR=3.50, 95% CI:1.09-12.50), male ( OR=6.79, 95% CI:2.87-17.81), those employed in enterprises and institutions ( OR=6.57, 95% CI:1.92-23.73) and hypertension ( OR=3.68, 95% CI:1.66-8.87) were positively correlated with hyperuricemia (all P<0.05). Conclusions:The prevalence of hyperuricemia among the middle- and older-aged population in the island of Taizhou City is significantly higher than that in the mountainous areas. Targeted comprehensive behavioral interventions such as routine screening of chronic diseases, low-fat diet, alcohol control, reduced seafood intake, enhanced exercise, weight management, and blood pressure control are warranted.

Objective:To retrieve, evaluate, and integrate evidence on the humanistic care practice of physical restraints for adult patients in the ICU to inform the management of physical restraints for clinical ICU patients.Methods:Expert consensus, group standards, systematic reviews, clinical decisions, best practices, guidelines, evidence summaries, and other types of literature related to the humanistic care of physical restraints for adult patients in the ICU were electronically searched in Chinese and English databases, relevant association websites, and guideline websites. The search period was from database establishment to August 31, 2024. Evidence was extracted and summarized according to themes after an independent literature quality assessment by two researchers.Results:A total of 15 articles were included, including four guidelines, one group standard, three best practices, five systematic reviews, and two expert consensus. Literature reading, evidence extraction and categorization resulted in seven themes of 39 best evidence on respecting patients' personality and dignity, attending to patients' physical needs, attending to patients' psychological needs, attending to patients' social and cultural needs, establishing good communication and trusting relationships, attending to patients' family and social support, and providing comprehensive nursing services.Conclusions:The best evidence summarized in this study may provide an evidence-based basis for the proper use of physical restraints by ICU medical and nursing staff to ensure patient safety and improve the ICU patient experience.

Objective:To describe the prevalence of non-alcoholic fatty liver disease (NAFLD) in people living with HIV in Taizhou, Zhejiang Province, and identify the factors associated with NAFLD in this population.Methods:A cross-sectional survey was conducted from 2021 to 2023. Based on the routine follow-up management of people living with HIV, liver ultrasound examination, physical examination and laboratory test were conducted to collect the information about the diagnosis of NAFLD and biochemical indicators in this population. Logistic regression model was used to identify the factors associated with the prevalence of NAFLD.Results:In the 2 550 study participants, the prevalence of NAFLD was 21.5% (548/2 550), abnormal liver function was found in 23.7% (604/2 550) of the study participants, and liver fibrosis was found in 45.2% (1 152/2 550) of the study participants. Multivariable logistic regression analyses showed that being women (a OR=0.55, 95% CI: 0.42-0.73), being overweight or obese (a OR=3.22, 95% CI: 2.59-4.01), having diabetes (a OR=3.37, 95% CI: 2.15-5.29), having dyslipidemia (a OR=2.96, 95% CI: 2.25-3.89), CD4 + T lymphocyte (CD4) counts <200 cells/μl (a OR=0.61, 95% CI: 0.42-0.88), and receiving Efavirenz (EFV) + Lamivudine (3TC) + Zidovudine (AZT) for antiretroviral therapy (ART)(a OR=1.52, 95% CI: 1.17-1.98) were associated with NAFLD. NAFLD was positively associated with abnormal liver function (a OR=2.01, 95% CI: 1.60-2.52) and inversely associated with liver fibrosis (a OR=0.76, 95% CI: 0.59-0.98). The 45-59 age group (a OR=7.05, 95% CI: 5.65-8.80), CD4 counts <200 cells/μl (a OR=1.45, 95% CI: 1.06-1.97) and receiving Nevirapine (NVP)+3TC+AZT of ART (a OR=1.87,95% CI: 1.44-2.43) were the main factors associated with liver fibrosis. Conclusions:The prevalence of NAFLD in people living with HIV Taizhou was more than 20.0%, with a significant proportion of them having abnormal liver function and liver fibrosis. Being overweight or obese, suffering from diabetes, having dyslipidemia, low CD4 counts, and receiving specific ART were associated with NAFLD. NAFLD, CD4 counts and specific ART were the main factors associated with abnormal liver function and liver fibrosis.

Objective:To investigate the life expectancy of antiretroviral treatment (ART) HIV-infected patients and its trends in Taizhou City, Zhejiang Province from 2014 to 2023.Methods:The data were obtained from the China Information System for Disease Control and Prevention , and the study subjects were HIV-infected patients received ART in Taizhou City. An abbreviated life expectancy table was prepared based on Chiang's method to analyze the differences in life expectancy of HIV-infected patients receiving ART in Taizhou City with different characteristics in 2023 and to compare the trends in life expectancy of patients with different CD4 +T lymphocytes (CD4) counts at the time of initiation of ART from 2014 to 2023. Results:A total of 4 825 patients were enrolled in this study, with a cumulative follow-up of 276 648.56 person-years, and a case-fatality rate of 18.07 (95% CI: 16.48-19.65) /1 000 person-years. In 2023, male patients had lower life expectancy than females in all age groups, and those who were married had higher life expectancy than those who were unmarried and those who were divorced or widowed; patients who had been transmitted heterosexually had lower life expectancy than those who had been transmitted through homosexual transmission. Patients with different CD4 counts at the time of initiating ART had different life expectancies in all age groups. The life expectancy of patients with CD4 counts ≥350 cells/μl when initiating the treatment was higher than that of patients with CD4 counts <200 cells/μl in all age groups. The life expectancy of HIV-infected patients on ART at age 20 and 50 increased from 39.0 years and 19.1 years in 2014 to 46.0 years and 24.1 years in 2023, respectively, with an average annual percentage change of 2.43% (95% CI: 0.81%-4.07%) and 3.34% (95% CI: 1.17%-5.56%). The change in life expectancy was similar for patients with CD4 counts ≥350 cells/μl and 200-349 cells/μl at the time of initiating treatment in 2016-2023, and was higher than that for patients with CD4 counts <200 cells/μl. The rate of increase in life expectancy for patients at age 50 was higher than that at age 20 for all CD4 counts. Conclusions:The rising trend of life expectancy among HIV-infected patients on ART in Taizhou City is obvious. But the disparity between patients with different characteristics is obvious, especially among patients with baseline CD4 counts <200 cells/μl, suggesting the importance of expanded testing, early diagnosis and timely initiation of ART to improve the life expectancy of HIV-infected patients.

Objective:To evaluate the role of NOD-like receptor protein 3 (NLRP3) inflammasome-mediated microglia activation in myocardial ischaemia-reperfusion-induced brain injury in mice.Methods:Fifty-two SPF healthy male wild-type C57BL/6 mice and 52 NLRP3 -/- mice, aged 8-10 weeks, were divided into 4 groups ( n=26 each) using a random number table method: wild type sham operation group (W-S group), wild type myocardial ischemia-reperfusion group (W-IR group), NLRP3 -/- sham operation group (NLRP3 -/--S group), and NLRP3 -/- myocardial ischemia-reperfusion group (NLRP3 -/--IR group). The myocardial ischemia-reperfusion-induced brain injury model was established by ligating the left anterior descending coronary artery for 45 min followed by 24 h of reperfusion in anesthetized mice. The cognitive function was evaluated using the modified Morris water maze test at 24 h of reperfusion. The mice were sacrificed after blood specimens were collected, and brain tissues were obtained for measurement of the blood-brain barrier permeability and water content, for microscopic examination of the pathological changes of brain tissues, and for determination of serum S-100β protein and neuron-specific enolase (NSE) concentrations, contents of interleukin-1 beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) in hippocampal tissues (by enzyme-linked immunosorbent assay), expression of NLRP3, apoptosis-associated speck-like protein (ASC), cleaved cysteine aspartate protease 1 (cleaved-caspase-1), gasdermin D (GSDMD), ionized calcium-binding adapter molecule 1 (Iba-1), and occludin in hippocampal tissues (by immunofluorescence and/or Western blot). The apoptosis rate of neurons and density of dendritic spine were calculated. Results:Compared with sham operation group, the escape latency was significantly prolonged, the number of crossing the original platform was decreased, and the time spent in the target quadrant was shortened, the concentrations of serum S-100β protein and NSE were increased, the blood-brain barrier permeability and brain water content were increased, the dendritic spine density in the hippocampal CA1 area was decreased, the contents of IL-1β, IL-6 and TNF-α were increased, the expression of NLRP3, ASC, cleaved-caspase-1, GSDMD and Iba-1 was up-regulated, and the expression of occludin was down-regulated ( P<0.05), and the pathological injury to brain tissues was found in ischemia-reperfusion group. Compared with W-IR group, the escape latency was significantly shortened, the number of crossing the original platform was increased, and the time spent in the target quadrant was prolonged, the concentrations of serum S-100β protein and NSE were decreased, the blood-brain barrier permeability and brain water content were decreased, the dendritic spine density in the hippocampal CA1 area was increased, the contents of IL-1β, IL-6 and TNF-α were decreased, the expression of NLRP3, ASC, cleaved-caspase-1, GSDMD and Iba-1 was down-regulated, and the expression of occludin was up-regulated ( P<0.05), and the pathological injury to brain tissues was alleviated in NLRP3 -/--IR group. Conclusions:NLRP3 inflammasome-mediated microglia activation is involved in myocardial ischaemia-reperfusion-induced brain injury in mice.

Objective:To evaluate the safety and effectiveness of fuzuloparib for the treatment of ovarian epithelial cancer patients in the real world setting.Methods:A retrospective analysis was conducted on the baseline data of 4 620 ovarian cancer patients who had received fuzuloparib monotherapy or combination therapy. Another 224 ovarian cancer patients who were willing to receive fuzuloparib monotherapy or combination therapy were prospectively enrolled, and their baseline characteristics, drug effectiveness, and safety data were analyzed.Results:(1) Among the 4 620 patients in the retrospective cohort, the median age of patients was 60 years; tumor types: 89.8% (4 149/4 620) had ovarian cancer. Among patients with clearly documented information, the vast majority had a histological type of serous carcinoma (82.9%, 3 770/4 546) and International Federation of Gynecology and Obstetrics (FIGO) staging of Ⅲ-Ⅳ (90.9%, 1 537/1 691). (2) Among the 224 patients in the prospective cohort, the median age of patients was 57 years; tumor types: 83.9% (188/224) had ovarian cancer. Among patients with clearly documented records, the predominant pathologic type was serous carcinoma (91.9%, 193/210), and FIGO stage was Ⅲ-Ⅳ in 79.9% (139/174). (3) Among the 224 prospective patients: 84 patients received first-line fluzoparib maintenance therapy, 92 patients received fluzoparib maintenance therapy after platinum-sensitive recurrence, 23 patients received direct fluzoparib treatment after platinum-sensitive recurrence, 19 patients received direct fluzoparib treatment after platinum-resistant recurrence. The median follow-up durations were 8.5, 8.7, 7.9, and 6.7 months, respectively. The median durations of fluzoparib treatment were 6.7, 4.8, 3.1, and 1.9 months, respectively. The median progression-free survival (PFS) times were not reached during follow-up, 12.6 months, not reached during follow-up, and 4.8 months, respectively. The 1-year PFS rates were 84.1%, 55.0%, 69.8%, and 45.5%, respectively. The remaining 6 patients received other fluzoparib regimens. (4) Among the 224 patients in the prospective dataset, 205 had safety data recorded. Of these, 127 patients (62.0%, 127/205) experienced treatment-related adverse events, with common events including anemia (24.4%, 50/205), thrombocytopenia (21.0%, 43/205), and leukopenia (19.5%, 40/205). Among the 205 patients, 43 (21.0%, 43/205) experienced grade 3 or higher treatment-related adverse events, with common events including anemia (8.3%, 17/205) and thrombocytopenia (8.3%, 17/205).Conclusions:The effectiveness of fuzuloparib in clinical application is generally consistent with other drugs in the same class, with good safety. This study provids new clinical evidence for the treatment of ovarian cancer with fuzuloparib.

Objective:To explore differences in the clinical and pathological features and postoperative survival after radical resection of biliary tract cancer in different locations such as intrahepatic cholangiocarcinoma,perihilar cholangiocarcinoma,distal cholangiocarcinoma,and gallbladder cancer.Methods:This is a retrospective case series study. The clinical and pathological data of 4 852 patients with biliary tract cancer admitted to the Department of Hepatobiliary Surgery,the First Affiliated Hospital of Xi ′an Jiaotong University from January 2013 to December 2022 were retrospectively analyzed. Among them, 2 110(43.49%%) patients were male and 2 742(56.51%) patients were female,aged from 26 to 88 years with age of (61.3±10.8) years. Observation indicators: (1) The distribution,diagnosis and treatment of patients with biliary tract cancer; (2) Comparison of clinical and pathological features of patients with biliary tract cancer after curative-intent resection; (3) Survival analysis of patients with biliary tract cancer after curative-intent resection; (4) Analysis of effect on adjuvant therapy for patients with biliary tract cancer after curative-intent resection. One-way analysis of variance,Kruskal-Wallis H test and χ 2 test were used for among-group comparisons,respectively. Survival univariate analysis was performed using the Kaplan-Meier method and Log-rank test. Results:Among the 4 852 patients with biliary tract cancer,there were 2 303 cases (47.46%) of gallbladder cancer,952 cases (19.62%) of intrahepatic cholangiocarcinoma,892 cases (18.38%) of perihilar cholangiocarcinoma,and 705 cases(14.53%) of distal cholangiocarcinoma. From the perspective of the year of diagnosis and treatment,the overall number of patients diagnosed and treated for biliary tract cancer has shown an upward trend. From the perspective of diagnosis and treatment,the curative-intent resection rate was 33.37%(1 619/4 852),and the curative-intent resection rate of distal cholangiocarcinoma was higher than that of other biliary tract cancer ( χ2=23.897, P<0.01). Univariate analysis showed that there were statistical differences in gender,age,bile duct stones,total bilirubin at admission,carcinoembryonic antigen,CA19-9,CA125,the degree of pathological differentiation,vascular invasion,microvascular invasion,perineural invasion,surgical margins,pT staging,and pN staging among patients for biliary tract cancer in different locations (all P<0.05). Survival comparison analysis showed that recurrence-free survival and overall survival of patients with gallbladder cancer after curative-intent resection were significantly better than those of intrahepatic cholangiocarcinoma,perihilar cholangiocarcinoma,and distal cholangiocarcinoma ( χ 2=87.780,83.717,both P<0.01). Comparing the postoperative prognosis of patients with biliary tract cancer between the two periods of 2013 to 2017 and 2018 to 2022, the results showed that recurrence-free survival and overall survival of patients with biliary tract cancer from 2018 to 2022 were significantly better than those from 2013 to 2017 ( χ 2=31.202,25.615, both P<0.01),and the proportion of early recurrence and short-term death after curative-intent resection was significantly reduced ( χ 2=21.588,9.623, both P<0.01),with gallbladder cancer being the most significant ( P<0.01). Postoperative adjuvant therapy for patients with biliary tract cancer can effectively prolong recurrence-free survival and overall survival ( χ 2=5.033,11.273,both P<0.05). Conclusions:Gallbladder cancer remains the most common biliary tract cancer with a relatively favorable prognosis after radical resection. There are significant differences in the clinical and pathological features of biliary tract cancer in different locations,and patients with adjuvant therapy effectively improving prognosis.

OBJECTIVE To investigate the in vitro antitumor activity and in vivo targeting of nanopolymers co-loaded with arse-nic trioxide(ATO),an active ingredient of traditional Chinese medicine arsenic,and photosensitizer(IR780)to activate the patient's own immune system in the treatment of brain glioma in synergistically with chemotherapy and phototherapy.METHODS PLGA/AI containing ATO and IR780 was prepared by volatilization with multiple emulsion solvent.The particle size,potential and polydispersity index(PDI)were determined by dynamic light scatterometer(DLS)at different feed ratios.Transmission electron microscopy(TEM)was used to detect the morphology of PLGA/AI.Fluorescence spectrophotometer was used to investigate the spectroscopic characteris-tics.UV-vis spectrophotometer was used to determine the drug loading and encapsulation rate of IR780.Under laser irradiation,the physiological release of ATO was measured by dialysis bag method.The uptake of PLGA/AI in GL261 cells was photographed by confo-cal microscopy(CLSM).The cell uptake mechanism of PLGA/AI was investigated by flow cytometry(FCM).3D tumor spheroid mod-el was constructed to simulate the deep penetration of PLGA/AI in solid tumors.The synergistic anti-tumor effects of PLGA/AI in vitro were studied by MTT assay and dying staining.DCFH-DA staining and FCM determination of the co-expression of CD80 CD86 co-stimulatory molecules verified the immune activation induced by PLGA/AI in vitro photochemotherapy.The in vivo targeting of PLGA/AI and the tissue distribution of the main organs were investigated by means of in vivo imaging of small animals after tail vein injection.RESULTS The optimal ratio of ATO to IR780 was 1∶10,its particle size was(134.11±2.19)nm,Zeta potential was(-7.02±0.649)mV,PDI was 0.254±0.059,and it was a uniform spherical shape under TEM.The fluorescence spectra showed that IR780 was successfully loaded onto PLGA,and the drug loading and encapsulation rate of IR780 in PLGA/AI were(2.53±0.02)%and(71.26±0.38)%respectively.The results of in vitro release experiments showed that ATO could be released in response to laser light by IR780-mediated photo-dynamics.Cell uptake experiments showed that the nano-polymer could effectively enter tumor cells under clathrin-mediated endocytosis.In vitro investigation of cell viability,ROS detection and dendritic cell maturation experiment showed that it could effectively kill tumor cells by inducing a large amount of ROS to generate and activate immune cells.In vivo targe-ting and biological distribution study confirmed that PLGA/AI could effectively penetrate BBB into tumor sites.CONCLUSION The active ingredients of traditional Chinese medicine arsenic,ATO and IR780,use PLGA as carriers to form nano-polymers through the volatilization of multiple emulsion solvents,which can cross the BBB and effectively accumulate at the tumor site.Based on"strengthe-ning the healthy qi and eliminating pathogenic factors"and combined with chemotherapy and photo-immune activation,it has the po-tential for long-term anti-glioblastoma treatment.
