Objective:To observe the efficacy of synchronous scalp acupuncture and rehabilitation training in the treatment of poststroke dysphagia.Methods:A total of 106 participants were divided into an observation group and a control group using the random number table method,with 53 cases in each group.The control group was treated with scalp acupuncture in addition to conventional rehabilitation training.The observation group was treated with synchronous scalp acupuncture and conventional rehabilitation training.Water swallowing test(WST),blood oxygen-saturation change amplitude,mini-mental state examination(MMSE),and standardized swallowing assessment(SSA)were assessed before treatment,after 2 weeks of treatment,and at follow-ups at week 4 and week 6.The effective rate was calculated based on the change in the WST grading after 2 weeks of treatment.Results:After 2 weeks of treatment,there was an insignificant difference in the total effective rate between the two groups(P>0.05),but the inter-group difference in the cured plus markedly effective rate was significant(P<0.01).The intra-group differences in the WST grading,blood oxygen-saturation change amplitude,and the scores of MMSE and SSA were significant among the 4 time points in the two groups(P<0.01).At follow-up at week 6,the WST grading and SSA score in the observation group were superior to those in the control group(P<0.01).Conclusion:Both intervention protocols can improve the swallowing function,physical function,and psychological status;the observation group's intervention is better than that of the control group in improving swallowing function.

Background The high work intensity and possible subsequently increased susceptibility to occupational hazards of calcium carbide plants may lead to hypertension in workers, but there are few studies on the relationship between occupational hazard exposure and hypertension in workers involving the production process of calcium carbide. Objective To explore the influence of occupational hazards on the incidence of hypertension in calcium carbide plants. Methods Using historical cohort design, the employees of a calcium carbide factory in the western part of Inner Mongolia Autonomous Region were selected as research subjects. According to the pre-determined inclusion and exclusion criteria, the study population comprised an exposure group of 377 employees (including furnace workers, inspection workers, and maintenance workers) exposed to dust, noise & carbon monoxide, and a control group of 388 employees (including central control workers, electricians, and administrative personnel) without above-mentioned exposure. The total sample size was 765 participants. The follow-up period was from April 2011 to October 2022, and the study endpoint was defined as the conclusion of the follow-up period or diagnosed hypertension in annual occupational health examination. Information on general demographic characteristics, living habits, and work status was collected from all study subjects. Cox proportional hazards regression model was used to analyze the association between occupational hazard exposure and the risk of hypertension among the calcium carbide plant employees. Results The average age, mean systolic and diastolic blood pressure, proportion of males, smoking rate, and alcohol consumption rate in the exposure group were higher than those in the control group (P<0.05). Compared to baseline, both systolic and diastolic blood pressure levels increased in the exposure group and the control group at the end of the follow-up (P<0.05). At the end of the follow-up, the average differences between systolic/ diastolic blood pressure and baseline values in the exposure group were higher than those in the control group (P<0.05). During the follow-up period, a total of 223 cases of hypertension occurred, with a total follow-up of 2785 person-years, resulting in an incidence density of 8007.18 per 100000 person-years, an average age of onset of (35.90±8.22) years, and an average working age of onset of (2.69±1.97) years. The incidence density in the exposure group was 128.71% higher than that in the control group, and the risk of hypertension in the exposure group was 2.115 times that of the control group. The risk of hypertension was 2.199 times higher for men than for women, 1.344 times higher for those aged 30 and above than for those under 30, 1.546 times higher for smokers than for non-smokers, and 1.750 times higher for drinking workers than for non-drinking ones. The results of Cox proportional hazards regression modeling indicated that the hazard ratio (95%CI) of hypertension among the employees exposed to dust, noise, and carbon monoxide was 2.254 (1.703, 2.982), 1.594 (1.107, 2.295), and 1.567 (1.079, 2.274), respectively, when different covariates (gender, age, smoking, and alcohol consumption) were included. The results of Log-rank test showed that there were statistically significant differences in the distribution of disease-free survival between the exposure group and the control group (P<0.05). Conclusion Occupational exposures to dust, noise, and carbon monoxide may increase the risk of hypertension among calcium carbide plant workers.

Objective:To investigate the mediating effect of family resilience on the relationship between psychological resilience and demoralization in leukemia patients undergoing chemotherapy.Methods:A total of 240 leukemia patients hospitalized for chemotherapy in the Department of Hematology, the First Affiliated Hospital of Zhengzhou University, from January to December 2024 were selected by convenience sampling. The Basic Information Questionnaire, Family Hardiness Index (FHI), Connor-Davidson Resilience Scale (CD-RISC), and the Chinese version of the Demoralization Scale Ⅱ (DS-Ⅱ) were administered. Pearson correlation analysis was used to examine the associations among family resilience, psychological resilience, and demoralization. A structural equation model was constructed with AMOS 21.0 to verify the mediating effect. A total of 240 questionnaires were distributed, of which 232 were valid, yielding a valid response rate of 96.67% (232/240) .Results:The mean scores of the 232 patients were as follows: FHI (51.41±8.27), CD-RISC (51.84±7.96), and DS-Ⅱ (21.03±4.19). FHI was positively correlated with CD-RISC ( P<0.05), while DS-Ⅱ was negatively correlated with both FHI and CD-RISC ( P<0.05). Psychological resilience had a direct negative effect on demoralization ( P<0.01), and family resilience also had a direct negative effect on demoralization ( P<0.01). Family resilience partially mediated the relationship between psychological resilience and demoralization ( P<0.01), accounting for 59.96% (-0.289/-0.482) of the total effect. Conclusions:Psychological resilience and family resilience in leukemia patients undergoing chemotherapy were both at moderate levels, while demoralization was relatively high. Family resilience partially mediated the relationship between psychological resilience and demoralization.

Objective:To explore the personality latent profiles of university first-year students and examine their associations with demographic characteristics,psychological symptoms,and major satisfaction.Methods:A to-tal of 52 783 first-year university students were assessed with the Minnesota Multiphasic Personality Inventory(MMPI),Beck Depression Inventory,Beck Anxiety Inventory,self-developed major satisfaction item and demo-graphic checklist.Data were analyzed with potential profile model,chi-square test,multiple logistic regression,co-variance analysis and median test.Results:Five latent profiles of MMPI among university freshmen were found,namely gender conflict group(23.4％),real healthy group(27.9％),defensive healthy group(37.3％),borderline-psychosis risk group(6.7％)and neurosis risk group(4.8％).Gender,grade period,childhood up bringers,par-ents'marital status and family atmosphere predicted differences between profiles of MMPI.Different profiles showed statistically meaningful differences at depressive symptoms,anxiety symptoms and major satisfaction.Conclusion:The latent profiles of MMPI among first-year university students demonstrate distinct classification patterns,diffe-ring demographic characteristics and psychologically problematic levels.

Objective:To investigate the predictive value of anti-Müllerian hormone (AMH) on the outcome of microscopic testicular sperm extraction (micro-TESE) in patients with non-mosaic Klinefelter syndrome (KS) of the clinical data and to identify effective predictors for successful micro-TESE.Methods:A retrospective case-control study was conducted on the clinical data of 118 non-mosaic KS patients treated at the Center for Reproductive Medicine of the First Affiliated Hospital of Zhengzhou University between May 2018 and September 2023. Patients were divided into two groups based on whether sperm were successfully retrieved via micro-TESE: the sperm retrieved group ( n=45) and the no sperm retrieved group ( n=73). Differences between the two groups were compared, and multivariate logistic regression analysis was used to identify factors influencing sperm retrieval. Changes in testicular volume and sex hormone levels before and after surgery were also assessed. Results:The sperm retrieval rate was 38.1% (45/118). Patients in the sperm retrieved group were significantly younger [(26.93±3.80) years] than those in the no sperm retrieved group [(28.27±3.92) years, P=0.029], and the AMH level was significantly higher [0.44 (0.18, 1.13) μg/L] than that in the no sperm retrieved group [0.10 (0.03, 0.22) μg/L, P<0.001]. AMH was identified as an independent predictor of micro-TESE outcome in non-mosaic KS patients ( OR=7.867, 95% CI: 2.727-27.242, P=0.001). The area under the receiver operating characteristic curve was 0.802 (95% CI: 0.722-0.883), and the optimal reference threshold for AMH was ≥0.265 μg/L. Postoperatively, testosterone levels decreased significantly by a median of 0.27 μg/L ( P=0.019), while luteinizing hormone levels increased by a median of 2.08 U/L ( P=0.049), with a more significant decline in testosterone levels observed in the no sperm retrieved group by a median of 0.29 μg/L ( P=0.022). Conclusion:AMH can predict successful micro-TESE in non-mosaic KS patients, with higher AMH levels indicating a higher likelihood of success.
