Objective:To investigate the effect of anoxic cold environment at 4500 m altitude on female men-struation.Methods:From March 1 to March 20,2023,women in a unit at an altitude of 4500 meters were selected for reproductive health questionnaire survey,and were divided into≤6 months group,6 months to 12 months group and≥12 months group according to altitude exposure time.The changes of menstruation in each group were analyzed to explore the relevant influencing factors.Results:The total incidence of abnormal menstruation in working women in hypoxic cold environment was as high as 66.14%,and there was no statistically significant difference between the groups at different high-altitude exposure times(P＞0.05).The highest incidence of dys-menorrhea among the types of menstrual changes was 61.90%,but there was no statistically significant differ-ence between the groups at different high altitude exposure times(P＞0.05).There was a statistically significant difference(P＜0.05)in the proportion of insufficient sleep for at least 3 days per week,nervousness and anxiety,and training during their menstrual period in the women who experienced changes in their menstrual cycle com-pared to those who did not.Conclusions:Hypoxic cold environment can lead to the change of female menstrua-tion,and it is combined with sleep deficiency,tension and anxiety,and menstrual exercise.

Objective:To explore the clinical characteristics and molecular basis for children and adolescents with monogenic diabetes.Methods:A retrospective analysis was carried out for the clinical manifestations and laboratory data of 116 children and adolescents diagnosed with diabetes at Ningbo Women and Children′s Hospital from January 2020 to March 2023. Whole exome sequencing and mitochondrial gene sequencing were carried out on 21 children with suspected monogenic diabetes.Results:A total of 10 cases of monogenic diabetes were diagnosed, all of which were Maturity-onset Diabetes Of the Young (MODY). Six cases of MODY2 were due to GCK gene mutations, 1 case of MODY3 was due to HNF1A gene mutation, 2 cases of MODY12 were due to ABCC8 gene mutations, and 1 case of MODY13 was due to KCNJ11 gene mutation. Nine of the 10 patients with MODY had no typical symptoms of diabetes. A family history of diabetes was significantly more common in the MODY group compared with the T1DM and T2DM groups ( P<0.05). The BMI of the MODY group was higher than that of the T1DM group ( P<0.05). The initial blood glucose level was lower than that of the T1DM group ( P<0.05), and there was no significant difference compared with the T2DM group. The fasting C-peptide level of the MODY group was higher than that of the T1DM group ( P<0.05), and there was no significant difference compared with the T2DM group. Glycosylated hemoglobin of the MODY group was lower than both the T1DM and T2DM groups ( P<0.05). Conclusion:In this study, MODY has accounted for the majority of monogenic diabetes among children and adolescents, and the common mutations were those of the GCK gene in association with MODY2. Blood glucose and glycosylated hemoglobin of children with MODY were slightly increased, whilst the islet cell function had remained, and the clinical manifestations and laboratory tests had overlapped with those of type 2 diabetes. WES and mitochondrial gene sequencing can clarify the etiology of monogenic diabetes and facilitate precise treatment.

OBJECTIVE To investigate the improvement effect and mechanism of triptolide （TP） on sciatica rats. METHODS Sciatica rat model was prepared and then randomly divided into model group （normal saline）， indomethacin group （positive control， 7.5 mg/kg）， TP low-dose and high-dose groups （TP-L group and TP-H group， 50， 100 μg/kg TP）， and high-dose TP+ stimulator of interferon gene （STING） activator group （TP-H+DMXAA group， 100 μg/kg TP+25 mg/kg DMXAA）， with 12 rats in each group. Another 12 unligated rats were selected as sham operation group （normal saline）. After 14 days of intraperitoneal administration， the paw mechanical withdrawal threshold （PWT） and paw withdrawal thermal latency （PWL） were detected； the pathological changes， morphology of sciatic nerve and the number of microglia in sciatic nerve were observed. The levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）， mRNA and protein expression levels of cyclic guanosine monophosphate- adenosine monophosphate synthase （cGAS） and STING in sciatic nerve were detected. RESULTS Compared with sham operation group， PWT and PWL of rats in model group were obviously reduced and shortened， the number of Nissl bodies was obviously decreased， while the number of microglia， sciatic neuropathology score， the levels of IL-1β and TNF-α， mRNA and protein expressions of cGAS and STING were obviously increased （P＜0.05）， and sciatic nerve injury was serious. Compared with model group， the changes of various indexes in indomethacin group， TP-L group and TP-H group were opposite to the above （P＜0.05）， and sciatic nerve injury was reduced. STING activator DMXAA weakened the inhibitory effect of TP on the activity of microglia and inflammatory response in sciatica rats （P＜0.05）. CONCLUSIONS TP may reduce the activity of microglia and inflammatory response by down-regulating the cGAS/STING signaling pathway， thus alleviating sciatica in rats.

Objective:To compare the influence of dronedarone and amiodarone on the bleeding risk of patients with atrial fibrillation treated with rivaroxaban anticoagulation.Methods:Clinical data of 81 patients with atrial fibrillation treated with rivaroxaban anticoagulation at Xi'an International Medical Center Hospital from January 2020 to July 2023, including 36 patients treated with dronedarone and 45 patients treated with amiodarone, were retrospectively analyzed. The effects of dronedarone and amiodarone on the anticoagulation of rivaroxaban were compared using the incidence of bleeding events, thrombosis events, and adverse reactions as outcome measures.Results:The total bleeding in the dronedarone group [22.22% (8/36)] was significantly higher than that in the amiodarone group [6.67% (3/45)] ( χ2 = 4.12, P < 0.05). The total bleeding of conventional-dose rivaroxaban in the dronedarone group was 30.00% (6/20), while the total bleeding of low-dose rivaroxaban was 12.50% (2/16), with no statistical significance ( χ2 = 1.58, P > 0.05). No thrombotic events or adverse reactions to dronedarone or amiodarone were observed in all patients. Conclusion:Compared with amiodarone, dronedarone significantly increases the bleeding risk of rivaroxaban anticoagulation in patients with non-valvular atrial fibrillation, and reducing the dose of rivaroxaban in patients using dronedarone does not reduce the bleeding risk.

Objective:To analyze whether triglyceride-glucose (TyG) index is associated with increased risk of cardiovascular diseases (CVD) and the value of TyG index in predicting CVD risk among Kazakh and Uighur population of Xinjiang.Methods:In this study, 5 375 Kazakh and Uygur people of Xinyuan county and Jiashi county were selected as the research objects. Subjects were divided into four groups based on the quartile of the TyG index level. Cox regression model was used to analyze the association between TyG index with the risk of CVD. The dose-response relationship between TyG index and CVD risk was described by restricted cubic splines. The area under the receiver operating characteristic curve, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to estimate the value of TyG index for predicting CVD. Mediating effect analysis was conducted to analyze the mediating effect of TyG index in the association between body mass index and CVD.Results:The age of subjects was 41.06（30.11，53.00）years old, with 46.30%（2 489/5 375）was male. After multivariate adjustment, there was an increasing trend between the risk of CVD and the higher TyG index Ptrend<0.001, compared with subjects of TyG index in Q1, the HR (95% CI) of Q2, Q3, and Q4 groups was 1.53, 1.23 and 1.73, respectively. Restricted cubic splines showed that TyG index was the linearly associated with the risk of CVD. TyG index could improve the prediction ability of Framingham model for the risk of CVD (NRI=0.106, P=0.010; IDI=0.003, P=0.030). The mediating effect analysis showed that in the relationship between body mass index and CVD, the TyG index had a mediating effect ( P<0.001), and the ratio of mediating effect was 12.69%. Conclusion:TyG index is an independent predictor of CVD risk among kazakh and Uygur population in Xinjiang and has a good predictive value for the risk of CVD.

Objective:To observe the clinical effect of scraping therapy on lumbar disc herniation (LDH) with different syndromes.Methods:Using the convenient sampling method, a total of 30 non-emergency LDH patients who were admitted to Department of Orthopedics and Traumatology of Yangzhou Hospital of Traditional Chinese Medicine from July 2017 to June 2018 were selected as the research objects. Among them, there were 11 cases of qi stagnation and blood stasis syndrome, 8 cases of damp-heat obstruction syndrome, 7 cases of cold-damp obstruction syndrome and 4 cases of liver and kidney deficiency syndrome. Du meridian, the bladder meridian of Foot Taiyang, as well as Jiaji (EX-B2) in pathological or painful sections, Ashi point, Shenshu (BL 23) , and Weizhong (BL 40) were mainly scraped. The treatment interval is 2~5 days (the marks of scrapping fade) , twice of scrapping as a treatment course and a total of 3 courses involved in the whole treatment. Japanese Orthopaedic Association (JOA) Score, Visual Analogue Scale (VAS) , serum interleukin-1 β (IL-1β) and interleukin-10 (IL-10) were compared before and after scraping.Results:Compared with those before scraping, the JOA score increased, the VAS decreased, the serum IL-1β content decreased and the serum IL-10 content increased after scraping, and the differences were sttaistically significant ( P<0.01) . Among them, the JOA scores of patients with qi stagnation and blood stasis syndrome and cold-damp obstruction syndrome were higher than those of damp-heat obstruction syndrome and liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . The levels of serum IL-10 in patients with qi stagnation and blood stasis syndrome, damp-heat obstruction syndrome and cold-damp obstruction syndrome were higher than those in patients with liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . Conclusions:The curative effect of scraping in the treatment of LDH is definite, and the curative effect is better for excessive syndromes.

The existing researches on scraping mostly focus on the observation of curative effect and preliminary attempts to explore the mechanism of action, but the research on scraping manifestation is slightly insufficient. At present, scraping manifestation studies mainly include skin appearance, skin blood perfusion, and skin temperature. These studies have laid the foundation and provided a reference for the standardization, normalization, and visualization research of scraping technology in the future. However, these studies are still in their infancy and need to be further studied.

Objective: To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population. Methods: A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves. Results: The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95%CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95%CI 0.805-0.901). Conclusions The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.
