Objective To understand the driver gene mutation status in patients with non-small cell lung cancer (NSCLC) in Xi'an City, and to analyze the association with environmental exposure factors. Methods A total of 305 NSCLC patients admitted to the First Affiliated Hospital of the Air Force Medical University from January 2019 to December 2023 were included. The driver gene mutation status was observed, and the relationship with environmental exposure factors was analyzed. Results The driver gene mutation rate of 305 patients was 46.89%, with EGFR gene mutation accounting for the highest proportion, and 4 cases of gene co-mutations were detected. There was a difference in gender among patients with different single drive gene mutations (P<0.05), and the proportion of EGFR in women was significantly higher (P<0.05). Univariate analysis showed that there were statistical differences in family history, smoking history, long-term cooking history, and fried smoked food intake between patients with driver gene mutation and patients without driver gene mutation (P<0.05). Logistic regression analysis suggested that long-term cooking history (OR=2.392), and fried smoked food intake (OR=2.849) were the environmental exposure factors affecting EGFR gene mutation (P<0.05), and smoking history (OR=1.377) was an environmental exposure factor of KRAS gene mutation (P<0.05). Conclusion EGFR gene mutation accounts for the highest proportion of NSCLC patients in Xi'an City, and is mainly female. Long-term cooking history, and fried smoked food intake are related to EGFR gene mutation. There is a certain association between smoking history and KRAS gene mutation.

Objective: To analyze the epidemiological and etiological characteristics of hand-foot-mouth disease (HFMD) in Tongren City during 2018 to 2022, so as to provide the reference for HFMD effective prevention and control. Methods: Monitoring data on HFMD in Tongren City from 2018 to 2022 was collected from National Infectious Disease Reporting Information Management System. Descriptive epidemiological method was conducted on the data analysis. Results: A total of 14 376 cases of HFMD were reported in Tongren City during 2018 to 2022, the average annual incidence rate of HFMD was 89.43/100 000. Totally 47 severe cases were reported, accounting for 0.33% of the total cases. The incidence rates of HFMD were generally declining trend during 2018 to 2022 (124.68/100 000, 95.37/100 000, 78.50/100 000, 61.63/100 000, 87.80/100 000) ( χ 2 trend =393.05, P <0.01), mainly occurred during April to July (48.13%), among children under 5 years old (95.72%). During 2018 to 2022, a total of 967 laboratory diagnosed cases reported in different years, regions, age groups showed significant differences in pathogen composition ratio ( χ 2=169.62, 456.65 , 167.96, P <0.05). From 2018 to 2022, the dominant pathogen of HFMD was constantly changing. Other enteroviruses were the dominant epidemic strains in 2018 and 2022 (33.04%, 37.62%), CoxA 6 was the dominant epidemic strain in 2019 to 2020 ( 68.75 %, 50.78%), and CoxA16 was the dominant epidemic strain in 2021(43.30%).In 2018, one case was infected with CoxA16 and EV71.The difference of pathogen composition ratio varied in different years ( χ 2=169.62, P <0.01). Conclusions The prevalence of HFMD in Tongren City has showed a declining trend during 2018 to 2022, and the dominant strain of HFMD has changed in recent years. The pathogen monitoring of HFMD should be strengthened to timely grasp the distribution and changes of pathogens, so as to provide a basis for the precise prevention and control of HFMD.

Objective:To explore the effect of foraging exercise (FE) on the behavior of rats with post-stroke depression (PSD) and the expression of 5-Hydroxytryptamine 1A (5-HT1A) receptor and transforming growth factor β1 (TGF-β1) in their frontal lobes.Methods:Thirty-six healthy male Sprague-Dawley rats were randomly divided into an ischemia-reperfusion (I/R) group, a PSD group and a PSD+ FE (FE) group, each of 12. The right middle cerebral artery of each was occluded using the thread occlusion method with 1.5h of ischemia. In the PSD and FE groups, mild stimulation was administered at unpredictable intervals over 3 weeks beginning 1 week after the successful modeling. The rats in the I/R group were raised in a group. Those in the PSD group were raised in individual cages. Those in the FE group were raised in a single cage and foraged freely for a total of 4 weeks. Four and eight weeks after the modeling, the body weights were measured, and the open field, social interaction (SIT) and sugar preference tests were administered to all of the groups. Four weeks later, all of the rats were sacrificed and their brains were sliced and stained. The expression of 5-HT1A receptor and TGF-β1 in the frontal lobe was detected using western blotting.Results:One week after modeling, there was no significant difference in average body weight or the average behavioral scores among the three groups. After four weeks the PSD and FE groups had significantly lower average body weight than the I/R group, fewer counts of rearing and grid crossing, longer SIT latency, less interaction time and lower average sugar preference (all significant differences). After eight weeks the average body weight had increased in each group. SIT latency had shortened and interaction time had increased in the FE group, and the rearing and grid crossing counts and sugar preference had increased in the PSD and FE groups. At that point the FE group had significantly greater average body weight than the PSD group, more counts of rearing and grid crossing, shorter SIT latency, increased interaction time, and greater sugar preference. The ratio of residual brain volume in the right hemisphere of the PSD and FE groups was significantly lower on average than in the I/R group. However, there was no significant difference in the right residual brain volume ratio between the PSD and FE groups. Staining revealed that the pathological changes in the frontal lobes of the FE group had been significantly relieved compared with the PSD group. Eight weeks after the operation the increases in average 5-HT 1A receptor and TGF-β1 levels in the FE group were significantly greater than in the PSD group.Conclusion:Foraging can relieve the depressive symptoms of rats modeling post-stoke depression. The mechanism may be related to alleviating the pathological damage and increasing the expression of 5-HT1AR and TGF-β1 in the frontal lobe. Early chronic stress may increase the volume of cerebral infarction, at least in rats.

Objective To explore the effects of hyperbaric oxygen ( HBO) combined with memantine hydrochloride in the treatment of Alzheimer's disease and its impact on the levels of serum SOD and NSE. Methods Eighty-eight patients with Alzheimer's disease admitted to our hospital from June 2015 to June 2018 were selected as the study subjects. The patients were divided into the combined group and the control group, in accordance with different treatment methods. The control group was treated with memantine hydrochloride, while the combined group was treated with HBO coupled with memantine hydrochloride. After 8 weeks of treatment, the clinical effects were compared between the patients of the 2 groups. Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were used to assess the cognitive status of the patients. The changes of serum SOD and NSE levels were compared and adverse reactions of the 2 groups were analyzed for the patients of the 2 groups. Results The total effective rate of the combined group (84. 09％)was obviously higher than that of the control group (63. 64％) (χ2 = 4. 768, P=0. 029). After treatment, the scores of MMSE and MoCA in the combined group were (21. 42 ± 1. 15) and (25. 46 ± 1. 39) respectively, while those in the control group were (18. 37 ± 1. 05) and (22. 31 ± 1. 22) respectively (all P<0. 05). Following treatment, the serum SOD levels of the 2 groups all increased, and the serum NSE level decreased (P<0. 05). No significant significance could be noticed in the rate of adverse reactions, when comparisons were made between the 2 groups (χ2 =0. 067, P=0. 769). Conclusion HBO combined with memantine hydrochloride in the treatment of Alzheimer's disease has good clinical efficacy, and could significantly improve the cognitive function of the patients, and increase serum SOD level, reduce NSE level and alleviate oxidative stress injury in the patients.

OBJECTIVE:To observe clinical efficacy and safety of triptorelin acetate in the treatment of endometriosis after lap-aroscopy. METHODS:196 cases of endometriosis were randomly divided into experimental group and control group with 98 cases in each group according to admission sequence. Both groups received laparoscopic surgery. After surgery,experimental group was given triptorelin acetate by intramuscular injection,3.75 mg/time,every 4 weeks;control group was given gestrinone orally,2.5 mg/time,twice a week,for 5 months. The ovulation,menstrual recovery and the occurrence of ADR were observed in 2 groups. The endometriosis relapse of 2 groups were followed up for 1 year and observed. RESULTS:After treatment,the ovulation recov-ery time and menstrual recovery time of experimental group were all shorter than those of control group,with statistical signifi-cance(P<0.05). The incidence of ADR in experimental group(17.34%)was significantly lower than in control group(35.71%), with statistical significance(P<0.05). During follow-up period,the relapse rate of experimental group(7.14%)was significantly lower than that of control group(18.37%),with statistical significance(P<0.05). CONCLUSIONS:After laparoscopic surgery, triptorelin acetate can significantly improve therapeutic efficacy of endometriosis,reduce the occurrence of ADR.
