ObjectiveTo evaluate the clinical efficiency of 0.1％ tacrolimus ointment combined with paroxetine in patients with neurodermatitis associated with insomnia.MethodsTotally,74 patients suffering from neurodermatitis and insomnia were consecutively enrolled in this study,and randomly assigned into the combination group and control group according to their number(odd or even).Both groups were given topical 0.1％ tacrolimus ointment twice a day,and the combination group was additionally given oral paroxetine 10 mg once a day,for 8 weeks.The outcome parameters included main symptoms of neurodermatitis and Pittsburgh sleep quality index(PSQI) score.ResultsNo significant difference was observed in the cure rate (54.3％(19/35) vs.53.1％ (17/32),P＞ 0.05) or response rate (82.9％ (29/35) vs.81.3％ (26/32),P＞ 0.05),between the combination group and control group.PSQI score was significantly lower in the combination group than in the control group after 8 weeks of treatment(P ＜ 0.05).ConclusionsThe 0.1％ tacrolimus ointment can be used to treat neurodermatitis safely.Antianxiety treatment can reduce the recurrence of neurodermatitis associated with insomnia,and improve the quality of sleep in patients.

Objective To investigate the changes in hydrogen sulfide(H_2S) level in plasma and myocardial tissues of doxorubicin-induced heart failure rats,and to study the role of H_2S in the development of doxorubicin-induced heart failure.Methods Male Wistar rats were randomly divided into 2 groups as follows:the doxorubicin group(n=12),in which 2.5 mg/kg of doxorubicin was injected intraperitoneal once a week for 10 weeks(total dose of 25 mg/kg);the control group(n=9),in which an(equivalent) volume of physiological saline was administered weekly for a total of 10 weeks.The observation of behavior was taken at the same time.Hemodynamic and echocardiographic measurements were obtained 10 weeks after treatment.Meanwhile,H_2S concentrations in serum and myocardial tissues were evaluated by modified sulfide electrode method.The changes of H_2S level between 2 groups were analyzed.Results The rats treated with doxorubicin showed inanimate behavior,decrease of the body temperature,activities and food intake,faster breathing,significant loss of weight,the cumulative mortality was 33%.Left ventricular systolic pressure(LVSP),difference of left ventricular pressure[△LVP=LVSP-left ventricular diastolic pressure(LVDP)] and left ventricular peak rate of contraction(+LV dp/dtmax),left ventricular peak rate of relaxation(-LV dp/dtmax)were significantly reduced in the group of doxorubicin rats(P

A PCR assay used for detection and quantification of Neotyphodium lolii in tissues of the grass Lolium perenne L. was developed. Compared with the Microscopic analysis of stained tissues, this method was more accurate. For quantitative applications, real time PCR was used to quantify Neotyphodium lolii in Lolium perenne L.. The results showed that there were some variations between different individuals, but no variance existed between different tillers from the same plant. Thus it can be concluded that fungal content in the plant is not only associated with species/variety specific, but also with the genotype of the host plant as well.

Compared with control group,the levels of each gland pituitary hormone in experimental group were significantly increased(P<0.05 ),and on the third day,the growth hormone (GH)was reduced significantly,finally 50%of that in control group. Conclusion Patients with brain injury treated with thyrotropin releasing hormone,has no significant adverse reactions,with the characteristics of safe and effective.

Objective To investigate the value of diffusion kurtosis imaging (DKI) in differential diagnosis of parotid gland disease and diagnosis of parotid adenolymphoma (PAL).Methods DKI and DWI data of 57 patients with parotid gland disease were etrospectively analyzed.Totally 57 cases were divided into infectious lesions group (n=10),pleomorphic adenoma group (n=19),PAL group (n=14),other benign parotid tumor group (n=4) and malignant parotid tumor group (n=10).Contralateral normal parotid glands in 19 patients with unilateral parotid gland lesions were treated as control group.The quantitative parameters including kurtosis concerning parameters (K Krad,Kax),diffusivity concerning parameters (D Drad,Dax),fractional anisotropy (FA) and conventional apparent diffusion coefficient (ADC) values were retrospectively reviewed.The binary Logistic regression method was used to confirm parameters with significant difference in diagnosing PAL.And Logistic regression equation was constructed to diagnose PAL.ROC analysis was conducted to evaluate the diagnostic value of the confirmed parameters and the Logistic regression equation.Results Significant difference of the parameters including K Krad,Kax,D Drad,Dax,FA and ADC values were found among different groups (all P＜0.05).ROC analysis demonstrated a higher area under the curve (AUC) for FA+Kax [0.88±0.06 (0.79-0.94)] than Kax[0.80±0.07 (0.70-0.88)] and FA [0.63±0.10 (0.52-0.73)],respectively (both P＜0.05).The sensitivity,specificity,accuracy,positive predictive value and negative predictive value was 71.43％,95.78％,91.77％,76.92％ and 94.44％.Conclusion DKI showed high diagnostic capacity in differential diagnosis of parotid gland disease.The combination of FA and Kaxcan improve the diagnostic accuracy in diagnosis of PAL.

Objective: To investigate the status of electronic cigarette use among adolescents in Ningxia Hui Autonomous Region, and to provide evidence for tobacco control in adolescents. Methods: Based on the 2019 National Youth Tobacco Epidemic Monitoring Program, multistage proportional sampling method was used to select middle school students from Ningxia Hui Autonomous Region. A questionnaire revised by Chinese CDC was used to collect the general information, the cognition and use of electronic cigarettes, and the access to advertising of electronic cigarettes and related products. Results: Totally 9 019 questionnaires were distributed, 8 401 valid ones were recovered, and the response rate was 93.2%. The rates of electronic cigarette use and attempt among students were 4.3% and 13.4%. The rates of electronic cigarette use and attempt in male students were 7.7% and 22.9%, which were higher than that in female students (0.8% and 3.8%, P<0.05) . The rates of electronic cigarette use and attempt varied in different schools ( P<0.05 ), which were higher in vocational high school students ( 11.5% and 26.8% ). Among 246 students who used electronic cigarettes, 30.1% did not thought electronic cigarettes contained nicotine, while 60.2% did not know whether electronic cigarettes contain nicotine. In the past 30 days, 27.0% of the students had seen the advertisements of electronic cigarettes and related products, mainly through TV, store, supermarket, convenience store, grocery store, electronic cigarette experience store or retail store. Conclusions The rates of electronic cigarette use and attempt among adolescents in Ningxia Hui Autonomous Region are 4.3% and 13.4%. Boys and vocational high school students have higher rates. Students generally know electronic cigarette and have more access to it.

Objective: To investigate the impact of physical self-efficacy on physical activity and physical health among university students, so as to provide insights into formulation of the strategy to improve physical activity and physical health among university students. Methods: Freshmen and sophomores were sampled from a university in Guangzhou City using a convenience sampling method from December 2021 to April 2022. Students' demographics and types of sport exercises were collected using questionnaire surveys. Physical self-efficacy was tested using the Physical Self-efficacy Scale, and physical activity was measured using the International Physical Activity Questionnaire-Short, while physical health was evaluated using the school physical health standard test. The associations of physical self-efficacy with physical activity and physical health were examined using a multivariable logistic regression model. Results: Totally 4 171 questionnaires were allocated, and 3 811 valid questionnaires were recovered, with a effective recovery rate of 91.37%. The respondents included 1 582 males (41.51%) and 2 229 females (58.49%), and included 1 967 freshmen (51.61%) and 1 844 sophomores (48.39%). The median score of physical self-efficacy was 36 (interquartile range, 7) points, and there were 1 777 students reaching the national standard of physical activity (46.63%) and 1 112 students with excellent and good physical health (29.18%). Multivariable logistic regression analysis showed that physical self-efficacy was a promoting factor for the proportion of reaching the national standard of physical activity (OR=1.054, 95%CI: 1.043-1.064) and excellent and good physical health (OR=1.109, 95%CI: 1.096-1.122) after adjustment for gender, grade, specialty and source of students. Conclusion The improvement of physical self-efficacy may increase the proportion of reaching the national standard of physical activity and excellent and good physical health among university students.
