Objective To investigate the epidemiological status of toxic diffuse goiter hyperthyroidism (abbreviated as hyperthyroidism) in Xining area and analyze its influencing factors. Methods Patients with toxic diffuse goiter and hyperthyroidism who were hospitalized in Class ⅲ Grade A hospitals in Xining from January 2020 to January 2023 were collected as the experimental group by random cluster sampling method. During the same period, 500 healthy people in each hospital were selected as the control group. The general data of the patients were collected and the levels of thyroid function indexes of the two groups were detected. Multivariate logistic regression was used to analyze the influencing factors of diffuse goiter with hyperthyroidism. Results A total of 718 questionnaires were collected in this study, and 705 questionnaires were collected after excluding invalid questionnaires. There were 234 males and 471 females in 705 patients with diffuse goiter and hyperthyroidism. The most common age was 41-50 years, followed by 51-60 years and 31-40 years. The serum TSH level of the experimental group was lower than that of the control group, and the levels of FT3 and FT4 were higher than those of the control group ( P < 0.05 ) . There was no significant difference in family history, thyroid texture and thyroid imaging between the two groups ( P > 0.05 ). There were significant differences in exophthalmos and thyroid weight between the two groups (P<0.05). Multivariate Logistic regression analysis showed that exophthalmos, thyroid weight ≥30g , TSH , FT3 and FT4 were independent risk factors for the experimental group ( P < 0.05) . Conclusion Gender, age, exophthalmos, thyroid weight and thyroid related hormone levels are the influencing factors of diffuse goiter and hyperthyroidism in Xining area . Thyroid function should be monitored for early prevention and treatment of the disease.

Objective To explore the mechanism of Marsdenia tenacissima in the treatment of breast cancer through network pharmacology and experimental verification.Methods Literature retrieval was conducted to obtain the active components of Marsdenia tenacissima.The SwissTargetPrediction database was used to predict the potential targets of these active components.Targets of breast cancer were obtained from GeneCards,GEPIA2,OMIM,PharmGKB and TTD databases.The intersection targets were obtained,and a Marsdenia tenacissima-breast cancer-targets network was constructed using Cytoscape 3.9.0 software.The core targets were identified through protein-protein interaction(PPI)network analysis,followed by GO and KEGG pathway enrichment analysis to screen relevant signaling pathways.Molecular docking validation was performed for the top 10 key targets and major active components.The human breast cancer cell line MDA-MB-231 was treated with Marsdenia tenacissima injection in vitro.Cell proliferation ability was detected by CCK-8 assay and colony formation assay.Cell apoptosis was detected by Calcein-AM/PI staining and flow cytometry.Cell migration ability was detected by Transwell assay.Western blot experiment was used to validate the PI3K-AKT signaling pathway.Results Totally 37 active components and 276 potential targets against breast cancer were screened from Marsdenia tenacissima,including 11alpha-O-Benzoyl-12beta-O-acetyl tenacigenin B,Caffeic acid,Drevogenin A and Kaempferol.25 core targets were screened by PPI network such as AKT1,EGFR,TNF,CTNNB1 and IL-6,which mainly affected the estrogen signaling pathway,ErbB signaling pathway,HIF-1 signaling pathway and PI3K-AKT signaling pathway,etc.The molecular docking results showed that the main active components of Marsdenia tenacissima exhibited good binding activities with the core targets AKT1,ALB,CASP3,ESR1 and TNF.The results of in vitro experiments showed that Marsdenia tenacissima injection could inhibit the proliferation and migration ability of MDA-MB-231 cells(P<0.01,P<0.001)and induce apoptosis(P<0.001),as well as inhibit the activation of PI3K-AKT signaling pathway(P<0.05,P<0.01).Conclusion Marsdenia tenacissima may exert its anti-breast cancer effects through multiple targets and pathways,and the mechanism may be related to the inhibition of PI3K-AKT signaling pathway.

Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Objective:To investigate the factors that influence the prolongation of gestation following emergency cervical cerclage.Methods:This retrospective study included 88 singleton pregnant women who were diagnosed with cervical incompetence and underwent emergency cervical cerclage at 12-26 weeks of gestation in the Jiaxing Maternity and Child Health Care Hospital from January 1, 2019 to September 1, 2022. The participants who delivered after 28 gestational weeks were assigned to the success group ( n=77), while those who delivered or miscarried before 28 gestational weeks were assigned to the failure group ( n=11). Two independent sample t-test or Mann-Whitney U test was used for comparison between groups. The factors affecting the prolongation of gestation after the procedure were selected by univariate analysis and multiple regression equations. Results:The success rate (delivery rate≥28 weeks) was 87.5% (77/88). There were six women delivered at 28-31 +6 weeks of gestation (6/77, 7.8%), two at 32-33 +6 weeks of gestation (2/77, 2.6%), 16 at 34-36 +6 weeks of gestation (16/77, 20.8%), and 53 at 37 weeks of gestation or later (53/77, 68.8%). Multiple regression analysis indicated that three times of early pregnancy miscarriage ( β=－5.1, 95% CI: -9.5 to -0.7), five times of early pregnancy miscarriage ( β=－11.8, 95% CI: -22.1 to -1.6), had two live births ( β=－6.9, 95% CI: -12.9 to -0.9), gestational age at cerclage ( β=－0.6, 95% CI: -1.0 to -0.3), external cervical os dilation<15 mm ( β=－12.1, 95% CI: -22.5 to -1.8) and ≥15 mm before cerclage ( β=－11.0, 95% CI: -21.4 to -0.71) were factors affecting the prolongation of gestation after cerclage. After adjusting for maternal age and weight before emergency cervical cerclage, five times of early pregnancy miscarriage ( β=－18.1, 95% CI: -28.3 to -7.8), gestational age at cerclage ( β=－0.6, 95% CI: -1.0 to -0.3), and external cervical os dilation≥15 mm before cerclage ( β=－11.4, 95% CI:－21.2 to -1.6) remained the significant influencing factors (all P<0.05). Conclusion:The number of early pregnancy miscarriages, gestational age at cerclage, and the width of external cervical os dilation before cerclage≥15 mm are the factors that influence the prolongation of gestation after the emergency cervical cerclage procedure.

In August 2nd Kunshan factory aluminum dust explosion accident 2014, 35 severe mass burn patients were admitted to our hospital, including 18 men and 17 women, aged 21 to 50 (38±9) years. Their severe injuries caused much difficulty to the treatment. In the early period of treatment, a series of measures of nursing human resource management were implemented, such as carrying out training program for non-burn speciality nurses of different levels and origin, grouping and task-dividing, organizing work schedule and assigning in a unified way, and establishing monitoring team of speciality quality. Except for 2 cases of deaths in the early period, the other 33 patients were treated and nursed timely and effectively in the early period. The rescue rate arrived at 94.3% (33/35) on the 17th day post burn. In this period, no such nursing adverse event and complication occurred as bed-dropping, unplanned extubation, coagulation in veins of lower limb, catheter-related infection, or cross infection.
