Objective To analyze the monitoring data of cardio-cerebrovascular diseases prevention and control system in Yichang in 2022, and to provide data support and experience for the precise prevention and treatment of cardio-cerebrovascular diseases. Methods Acute cardiovascular and cerebrovascular event data were collected from the Yichang Cardio-cerebrovascular Events Monitoring System from January 1, 2022 to December 31, 2022. Descriptive analysis was conducted for the data collected. Statistical analysis was performed using SPSS 20.0 software, and a chi-square test was used to analyze the count data. Results A total of 37,217 cases of cardio-cerebrovascular events were monitored in Yichang in 2022. The crude incidence and the standardized incidence were 983.84/100,000 and 541.55/100,000, respectively. The incidence in males was higher than females (554.93/100,000 vs 428.91/100,000,χ2 =464.52,P<0.05). The top three diseases were cerebral infarction, acute myocardial infarction, and cerebral hemorrhage. The incidence of events increased with age, and 79.80% of the cases were over 60 years old. The main onset time was from May to August. Conclusion The use of the cardio-cerebrovascular events monitoring system in Yichang and the implementation of “mandatory reporting card” monitoring can timely obtain the epidemic characteristics of the diseases, provide support for the precise formulation of prevention and control strategies and measures, reduce underreporting rates, and improve the monitoring system, which is worthy of reference and promotion.

To evaluate the safety and efficacy of oral double-balloon enteroscopy for small intestinal bezoars with obstruction, the clinical, endoscopic, imaging, pathological and surgical data of patients with small intestinal bezoars and obstruction treated in Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from December 2021 to March 2023 were retrospectively analyzed. A total of 5 patients, all female, aged 52-83 years, were included. The clinical manifestation was mainly digestive tract obstruction. The diameter of bezoars was 30-50 mm. Three were located in the jejunum, one in the proximal ileum, and one at the jejuno-ileal junction. Three cases were diagnosed as having small intestinal bezoars by imaging examination before operation. All 5 patients achieved technical success. Four patients achieved clinical success, the symptoms of obstruction were completely relieved, and 1 patient was partially relieved due to malignant obstruction. No obvious complication occurred in 5 patients after operation. The follow-up time was 15-790 days, and there was no recurrence. The results showed that oral double-balloon enteroscopy for small intestinal bezoars was safe and effective, providing a new treatment for patients with small intestinal bezoars except for surgery.

Objective:To explore the impact of unidentified injectable fillers on the soft tissue of nasal dorsum and rhinoplasty.Methods:The Plastic Surgery Information System of Xinhua Hospital Affiliated with Dalian University was utilized to conduct an analysis of 62 rhinoplasty patients between 2018 and 2019. Specifically, this included 28 patients with an unidentified history of injectable filler rhinoplasty, encompassing 1 male and 27 females with ages ranging from 19 to 53 years and a mean age of 28.8 years. Additionally, 34 patients underwent primary rhinoplasty, all of whom were female with ages ranging from 19 to 46 years and a mean age of 26.8 years. This study examined the effects of unidentified injectable fillers on the soft tissue of the nasal dorsum by analyzing the excised nasal dorsum under a microscope. Subsequently, statistical methods were performed to assess differences in gender, age, preoperative tip protrusion/nose length, postoperative tip protrusion/nose length, dorsal augmentation modality, and satisfaction, and to investigate the effect of unidentified injectables on the rate of dissatisfaction after rhinoplasty.Results:The histopathological analysis of unidentified injectable fillers removed from the nasal dorsum revealed the presence of mainly gel and granular fillers. The gel fillers, characterized by its pink jelly-like texture, contained unidentified injectable fillers, colorless glue, and were observed to flow out upon cutting. The granular filler, on the other hand, appeared as tough, irregularly shaped tissue similar to caviar. Additionally, evidence of muscle tissue in 5 pathologic sections indicated that the unidentified injectable fillers were injected into or near the dorsal nasal muscles, leading to varying degrees of muscle injuries upon excision. A comparison of 28 rhinoplasty patients with unidentified injectable fillers for nasal dorsal augmentation and 34 patients with primary rhinoplasty showed that 11 females in the former group and 4 females in the latter group were dissatisfied with the results. Statistical analysis demonstrated no significant differences between the two groups in terms of gender ( P=0.452), age ( P=0.219), preoperative tip projection/nasal length ( P=0.681), postoperative tip projection/nasal length ( P=0.105), and nasal dorsum augmentation methods ( P=0.413). However, the initial rhinoplasty group had a lower dissatisfactory rate (4 cases, 11.76%) and the unidentified injectables group had a higher dissatisfactory rate (11 cases, 39.29%), which was statistically significant between the two groups (χ 2=6.341, P=0.012). Conclusions:The presence of unidentified nasal injectable fillers can significantly decrease postoperative satisfactory rates, increase the incidence of dissatisfaction, and have adverse effects on the soft tissues of the nasal dorsum and the overall outcome of the rhinoplasty procedure.

There were 142 male infected cases (60.17%) and 94 female cases (39.83%); there was a statistically significant difference in the virus detection rate between the male group (91.55%) and the female group (78.72%) ( χ2=7.938, P=0.005). In the seasonal distribution, the summer group had the highest constituent ratio (40.25%), while the winter group had the lowest constituent ratio (11.86%), The composition ratio of the summer group was significantly higher than that of the other groups, and the differences were statistically significant ( χ2=10.393, 19.199, 49.358, all P<0.001). The virus detection rate in the summer group was significantly higher than that in the spring group and the winter group ( χ2=16.951, 4.592, both P<0.05). The RT-PCR result showed that a total of 204 out of 236 children with herpetic angina were virus positive, with a detection rate of 86.44% (204/236), including coxsackievirus A (CV-A) 6 (22.55%), CV-A16 (5.88%), CV-A2 (2.94%), enterovirus type A71 (EV-A71) (2.94%), and other enteroviruses (65.69%). The RT-snPCR result showed that five viruses were identified from other enteroviruses, including CV-A4 (8.33%), CV-A5 (6.86%), CV-A10 (12.25%), CV-A12 (24.02%), and coxsackievirus B3 (CV-B3) (6.86%); another 15 positive samples of enterovirus were not successfully classified. We selected 9 strains of the virus in this study and 30 reference sequences from the NCBI database to. Conclusions:Herpetic angina in eastern region of Chengdu in 2022 is mainly found in male children under 3 years of age, and was concentrated between April and June. It has been confirmed that CV-A12 and CV-A6 were more common in intestinal viruses, and the 9 strains isolated in this study were homologous to multiple isolates.

Objective To understand the health-related quality of life (HRQoL) and its influencing factors in Jilin province and compare two life quality measurement methods. Methods The data of 13 700 people aged above 15 years in Jilin province were extracted from the National Health Services Survey 2013. Self-rated health scores and EuroQol 5-dimension utility values were used to evaluate the HRQoL. Multivariable linear regression model was used to analyze the influencing factors. Results The self-rated health score was 81.26±15.73 in Jilin province,while utility values of health status were 0.959±0.124. The influencing factors of HRQoL included age,residency,education,income,type of health insurance,having non-communicable chronic disease and having disease in last two weeks. The age under 45,income,having non-communicable chronic disease,and having disease in last two weeks had stronger effect on self-rated health,whereas residency and type of health insurance had more effect on utility values of health status. Conclusion People in Jilin province have good quality of life. Both methods have their advantages and weakness. It is important to choose the right evaluation method depended on the objective of a specific study.

Echinomycin is a small-molecule inhibitor of hypoxia-inducible factor-1 DNA-binding activity, which plays a crucial role in ovarian ovulation in mammalians. The present study was designed to test the hypothesis that hypoxia-inducible factor (HIF)-1alpha-mediated endothelin (ET)-2 expressions contributed to ovarian ovulation in response to human chorionic gonadotropin (hCG) during gonadotropin-induced superuvulation. By real-time RT-PCR analysis, ET-2 mRNA level was found to significantly decrease in the ovaries after echinomycin treatment, while HIF-1alpha mRNA and protein expression was not obviously changed. Further analysis also showed that these changes of ET-2 mRNA were consistent with HIF-1 activity in the ovaires, which is similar with HIF-1alpha and ET-2 expression in the granulosa cells with gonadotropin and echinomycin treatments. The results of HIF-1alpha and ET-2 expression in the granulosa cells transfected with cis-element oligodeoxynucleotide (dsODN) under gonadotropin treatment further indicated HIF-1alpha directly mediated the transcriptional activation of ET-2 during gonadotropin-induced superuvulation. Taken together, these results demonstrated that HIF-1alpha-mediated ET-2 transcriptional activation is one of the important mechanisms regulating gonadotropin-induced mammalian ovulatory precess in vivo.
