BACKGROUND:To build up an effective method of isolating and culturing granule cels is a pivotal step to enhance fertilization-embryo transfer rate. Current studies mainly focus on the isolation methods of human ovarian granulosa cels rather than cel counting, purity and subsequent growth. OBJECTIVE: To establish the effective methods of isolating, purifying and culturing human ovarian granulosa cels in vitro. METHODS: Folicular fluid was harvested from women undergoing fertilization-embryo transfer procedures. Human ovarian granulosa cels were obtained from the folicular fluid by lysis treatment, precipitation method or density gradient centrifugation. Granulosa cel mucus masses were digested with type I colagen enzyme or hyaluronidase and then cultured in the culture medium with or without autologous folicular fluid. RESULTS AND CONCLUSION: Lysis treatment yielded the largest amount of granulosa cels compared to the precipitation method and density gradient centrifugation (P > 0.05,P < 0.05, respectively). Cels prepared by the three methods showed the same cel viability. After 24 hours of culture, the precipitation method obtained the largest amount of adherent granulosa cels (P < 0.05); and the density gradient centrifugation obtained the least amount of cels (P < 0.05). Compared with type I colagen enzyme, hyaluronidase took less time to digest the cels thoroughly. Autologous folicular fluid could promote the growth and survival of granulosa cels. These findings indicate that the precipitation method, though time-consuming, can obtain the highest cel viability and harvested the largest amount of granulosa cels after culture; hyaluronidase is more suitable for digesting granulosa cel mucus mass than type I colagen enzyme; autologous folicular fluid added into the culture medium is more conducive to granulosa cel growth.

PURPOSE: The Pipeline embolization device (PED) is approved in the USA for treating giant and large aneurysms arising from the petrous to superior hypophyseal segments of the internal carotid artery in patients older than 21 years of age. This study investigates off-label PED results in a large cohort. MATERIALS AND METHODS: Retrospective, single-center review of all patients who had off-label PED surgery. RESULTS: Sixty-two aneurysms (48 patients) underwent off-label PED treatment from 2012–2017. There were 44 females and four males (age 21 to 75 years; mean/median, 54.3/55.0 years). The most common presenting symptom was headache (47/62, 75.8%). All aneurysms were in the anterior circulation. Aneurysm size ranged from 1.4 to 25.0 mm (mean/median, 7.6/6.9 mm). Fifty-two aneurysms had post-operative imaging with total/near-complete occlusion of 84.6% (44/52). Aneurysm-based operative near-term complication rate was 9.7% while there were no permanent complications. For aneurysms and headache, 86.7% improved/resolved after embo-surgery, and were four times more likely to have a better clinical outcome (resolved or improved symptoms) after surgery (odds ratio [OR], 4.333; P=0.0325). Left-sided aneurysms had a higher occlusion rate (OR, 20; P=0.0073). Hypertension (OR, 4.2; P=0.0332) and smoking (OR, 7; P=0.0155) were more prone towards aneurysm occlusion. Patients without a family history were 14 times more likely to have favorable imaging outcome (P=0.0405). There is no difference of occlusion rates between untreated and previously treated aneurysms (P=0.6894). Overall, occlusion rate decreased by 14% with an increase of aneurysm size by 1 mm (P=0.0283). CONCLUSION: For anterior circulation aneurysms, the off-label application of PED is as effective and safe as reported for on-label intracranial aneurysms.

OBJECTIVETo establish a zebrafish model of liver fibrosis via diethylnitrosamine (DEN)-induced liver injury.
METHODSA total of 120 wild-type 3-month-old zebrafish were randomly divided into DEN-treated group and control group. The survival rate and behavioral changes of each group were observed. After treatment with DEN for 2, 4, and 6 weeks, liver index was measured, and liver fibrosis was evaluated with HE staining, Gomori staining and Sirius red staining.
RESULTSNo obvious behavioral change was observed in DEN-treated group during the experiment. Compared with that in control group, the liver index of zebrafish in DEN-treated group showed no significantly changes at the time points of observation. Proliferation of reticulate fibers was found in 30% of zebrafish treated with DEN for 4 weeks, and the rate increased to 80% at 6 weeks when reticulate fibers and collagen fibers actively proliferated to result in fiber collapse and formation of fibrotic nodules.
CONCLUSIONA stable zebrafish liver fibrosis model was successfully established by inducing liver damage to facilitate studies of the pathogenesis of liver fibrosis and screening therapeutic drugs.

Objective:To compare the effect and safety of continuous veno-venous hemofiltration (CVVH)+double plasma molecular absorption (DPMA)+hemoperfusion (HP), CVVH+HP, and CVVH+plasma exchange (PE) in treatment of patient with severe wasp stings injury.Methods:Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group). Propensity score matching was used to establish historical cohorts. Patients with severe wasp sting injury who hospitalized from January 2016 to June 2020 in each ICU were collected and matched 1∶1 with the intervention group, and divided into CVVH+HP group and CVVH+PE group according to their actual hemopurification protocols (historical control groups). The primary outcome was the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on days 3 and 7 after initiation of treatment. Secondary outcomes included complications, length of ICU and hospital stays, and all-cause mortality. Multivariate Cox proportional risk regression was used to analyze the prognosis of patients.Results:After propensity score matching, 56 patients in intervention group and each of the two historical control groups were matched successfully. There were no significant differences in age, gender, comorbidities, biochemical test indices and critical illness scores among the groups. After treatment, APACHE Ⅱ score markedly declined in all groups, and the decrease was faster in the intervention group; treatment with DPMA [hazard ratio ( HR) = 1.04, 95% confidence interval (95% CI) was 1.02-1.08, P = 0.00], the decreased levels of body temperature ( HR = 1.02, 95% CI was 1.00-1.03, P = 0.02), serum creatine kinase (CK; HR = 0.98, 95% CI was 0.96-1.00, P = 0.05) and myoglobin (MYO; HR = 2.88, 95% CI was 1.24-6.69, P = 0.01) were independent risk factors for APACHE Ⅱ score decline to the target value (15 scores). There were no significant differences in the incidence of bleeding complications, filter or perfusion thrombosis, blood pressure reduction, catheter-related infection and anaphylaxis among the groups. Conclusion:CVVH+DPMA+HP regimen can significantly reduce the APACHE Ⅱ score of patients with severe wasp sting injury, and the efficacy is superior to CVVH+HP and CVVH+PE regimens, with safety.

Objective:To understand the epidemiological characteristics and trends of injury in older adults in Jiangsu Province from 2006 to 2022 and provide a scientific basis for developing prevention and control measures.Methods:The data on injury cases aged 60 and older were collected from 12 sentinel hospitals in Jiangsu Province during 2006-2022. The study analyzed the proportion of injury cases among the elderly in the overall population and calculated the annual percent change and average annual percent change (AAPC). A pairwise comparison between groups was performed, and the differences were judged according to the adjusted standardized residuals.Results:From 2006 to 2022, there were 218 426 injury cases among individuals aged 60 and older in Jiangsu Province, which accounted for an increasing proportion of injury cases within the entire population (AAPC=3.17%, P<0.001). The first five causes of elderly injury were falls (42.06%), road traffic injuries (20.20%), animal injuries (11.45%), knife/sharp injuries (9.43%), and blunt injuries (8.13%). From 2006 to 2022, the proportion of falls, animal injuries, and knife/sharp injuries among the elderly aged ≥60 showed an increasing trend, while the proportion of road traffic injuries and blunt injuries decreased (all P<0.001). The incidence of injury was highest in October, with a daily incidence peak between 8:00 and 10:00. Leisure activities (40.34%) were the major activity leading to injury. The injury occurred mainly at home (53.74%), and the injury intention was mainly unintentional (97.41%), all of which showed an increasing trend ( P<0.001). The injuries were mainly bruises (36.00%), and the most common injured positions of the body were low limbs (27.55%), all of which showed a decreasing trend ( P<0.001). About 69.80% of cases were slight, and 79.38% were discharged after treatment, which showed an increasing trend ( P<0.001). Conclusions:The injury data for individuals aged 60 and older in Jiangsu Province exhibited varying trends from 2006 to 2022. There was a noticeable increase in the proportion of elderly injury cases within the overall injury population, as well as an upward trend in falls, animal injuries, and knife/sharp injuries as leading causes of injury. It is imperative to actively develop prevention measures based on the epidemiological characteristics and evolving trends of elderly injuries in Jiangsu Province.

Objective:To analyze the comorbidity status and influencing factors of hypertension, diabetes, and dyslipidemia among middle-aged and elderly in Jiangsu Province and to provide support for "co-management of the three diseases".Methods:Data originated from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases baseline survey in Jiangsu Province. Questionnaire interviews, physical examinations, and laboratory tests were conducted on 136 433 permanent residents aged ≥35 years who participated in the survey from 2021 to 2023. A multinomial logit model was established using SPSS 23.0 to analyze the influencing factors of the three comorbidities.Results:The comorbidity rate of hypertension, diabetes, and dyslipidemia among middle-aged and older adults in Jiangsu Province was 7.3%. Hypertension combined with dyslipidemia was the main comorbidity pattern, and patients with diabetes accounted for the largest proportion. Multinomial logistic regression analysis showed that the risk of being two types of the three comorbidities was higher in male, aging, urban residents, and those with high/technical secondary school, higher frequency of cigarette smoking and alcohol drinking, and longer daily sedentary time; the risk was lower in those with higher the level of physical activity and longer daily sleep time. Among the three types of comorbidities, males with aging, high/technical secondary school, regular smoking/quitting, higher frequency of alcohol drinking, and longer daily sedentary time had higher risk; those with an annual family income of 30 000-99 999 RMB, higher level of physical activity, and the daily sleep time of 7 hours had the lower risk (all P<0.05). Conclusions:The prevention and control of the three comorbidities among middle-aged and older adults in Jiangsu Province still needs strengthening. High-risk groups for the three diseases and comorbidities, such as males, low-income , and high/technical secondary school should be focused on. Middle-aged and older adults are suggested to increase daily physical activity, reduce daily static time, reasonably arrange sleep duration, and quit smoking and drinking as early as possible to maintain a healthy weight.
