Objective·To evaluate the changes in cognitive function in overweight and obese adolescents,and explore the association between cognitive function and fibroblast growth factor 21(FGF21).Methods·A total of 175 adolescents from a senior high school in Shanghai were divided into normal weight group(n=50),overweight group(n=50)and obese group(n=75)based on their body mass index(BMI).General information,anthropometric data and laboratory testing indicators of the adolescents were collected and compared.The cognitive function of the three groups of adolescents was assessed by using the accuracy(ACC)and reaction time of Flanker task and n-back task.Enzyme-linked immunosorbent assay(ELISA)was used to detect the serum FGF21 level of the three groups of adolescents.Partial correlation analysis and multiple linear regression model were used to evaluate the correlation between cognitive task performance and anthropometric data and laboratory testing indicators.Results·Compared with the normal weight group,systolic blood pressure,diastolic blood pressure,and the levels of fasting plasma glucose,glycosylated hemoglobin and triacylglycerol in the obese group were higher(all P<0.05).Under congruent or incongruent stimulus conditions in the Flanker task,there was no significant difference in ACC between any two groups;compared with the normal weight and overweight groups,the reaction time of the adolescents in the obese group was prolonged(all P<0.05).In the n-back task,there were no significant differences in ACC between any two groups,while the obese group had longer reaction time in the 1-back and 2-back tasks compared to the normal weight and overweight groups(all P<0.05).Compared with the normal weight group,serum FGF21 levels of the adolescents in the obese group were higher(P=0.000).Partial correlation analysis showed that the reaction time of the adolescents in Flanker and n-back tasks was correlated with their BMI,body fat mass,waist circumference,waist-to-hip ratio and FGF21 level(all P<0.05).Multiple linear regression analysis further confirmed that BMI was associated with prolonged reaction time in cognitive-related behavioral tasks in the adolescents(all P<0.05),and FGF21 level was associated with ACC in the 2-back task(P=0.000)and reaction time in the incongruent stimulus condition(P=0.048).Conclusion·Overweight and obese adolescents have cognitive impairments,and BMI and serum FGF21 levels are associated with changes in their cognitive function.

Objective This paper intends to compare the efficacy and safety of high-dose dual regimens containing Vonoprazan and proton pump inhibitor in patients infected with Helicobacter pylori(H.pylori).Methods A prospective randomized controlled study was conducted.According to inclusion and exclusion criteria.,243 patients with H.pylori infection admitted to the Department of Gastroenterology,the First Hospital of Lanzhou University from February 2023 to December 2023 were enrolled as the research objects.They were randomly divided into two groups.The high-dose dual therapy containing Vonoprazan group(VPZ-HDDT group)was given Vonoprazan fumarate tablet 20mg twice daily plus amoxicillin 750 mg four times daily for 14 days and the high-dose combination group containing PPI(PPI-HDDT group)was given esomeprazole 40 mg twice daily plus amoxicillin 750 mg four times daily for 14 days.Patients were followed up and recorded by telephone or WeChat on the 7th and 14th day of starting treatment for drug intake and occurrence of adverse reactions.Patients were instructed to recheck the 13C or 14C urea breath test at least 1 month after the end of medication.Treatment by protocol(PP)analysis,modified intention to treat(mITT)and intention-to-treat(ITT)analysis were used for H.pylori eradication rates in both groups,and compliance and incidence of adverse reactions were compared between the two groups.Results The eradication rates of the VPZ-HDDT group and the PPI-HDDT group in the initial treatment were 94.0％and 88.5％(P=0.209)by PP analysis,and 91.8％and 87.5％(P=0.358)86.7％by mITT analysis,and 81.9％(P=0.377)by ITT analysis,respectively.In the retreated patients,the PP analysis and mITT analysis eradication rates in these two groups were consistent,87.0％and 84.2％(P=0.800),respectively,and 83.3％and 76.2％(P=0.550)by ITT analysis.For the refractory H.pylori patients,the PP analysis and mITT analysis eradication rates in these two groups were also consistent,71.4％and 50.0％(P=0.429),and the eradication rates of ITT analysis were 62.5％and 50.0％(P=0.640),respectively.In different stratifications,the eradication rates of the VPZ-HDDT group were higher than those of the PPI-HDDT group,but the differences were not statistically significant.The incidence of adverse reactions and compliance of the VPZ-HDDT group and the PPI-HDDT group were similar,with no statistically significant differences.Conclusion Both two combination regimens can achieve clinically acceptable eradication rates(＞85％)in the first-time treatment patients.For the retreated and refractory patients,the choice of vonoprazan is more beneficial.

This study compared the ameliorating effects of L-borneol, natural borneol, and synthetic borneol on the injury of different brain regions in the rat model of acute phase of cerebral ischemia/reperfusion(I/R) for the first time, which provides a reference for guiding the rational application of borneol in the early treatment of ischemic stroke and has important academic and application values. Healthy specific pathogen-free(SPF)-grade SD male rats were randomly assigned into 13 groups: a sham-operation group, a model group, a Tween model group, a positive drug(nimodipine) group, and high-, medium-, and low-dose(0.2, 0.1, and 0.05 g·kg~(-1), respectively) groups of L-borneol, natural borneol, and synthetic borneol according to body weight. After 3 days of pre-administration, the rat model of I/R was established by suture-occluded method and confirmed by laser speckle imaging. The corresponding agents in different groups were then administered for 1 day. The body temperature was monitored regularly before pre-administration, days 1, 2, and 3 of pre-administration, 2 h after model awakening, and 1 d after model establishment. Neurological function was evaluated based on Zea-Longa score and modified neurological severity score(mNSS) 2 h and next day after awakening. The rats were anesthetized 30 min after the last administration, and blood was collected from the abdominal aorta. Enzyme-linked immunoassay assay(ELISA) was employed to determine the serum levels of tumor necrosis factor-alpha(TNF-α), interleukin-6(IL-6), IL-4, and transforming growth factor-beta1(TGF-β1). The brain tissues were stained with triphenyltetrazolium chloride(TTC) for the calculation of cerebral infarction rate, and hematoxylin-eosin(HE) staining was used for observing and semi-quantitatively evaluating the pathological damage in different brain regions. Immunohistochemistry was employed to detect the expression of ionized calcium binding adapter molecule 1(IBA1) in microglia. q-PCR was carried out to determine the mRNA levels of iNOS and arginase 1(Arg1), markers of polarization phenotype M1 and M2 in microglia. Compared with the sham-operation group, the model group and the Tween model group showed significantly elevated body temperature, Zea-Longa score, mNSS, and cerebral infarction rate, severely damaged cortex, hippocampus, and striatum, increased serum levels of IL-6 and TNF-α, and decreased serum levels of IL-4 and TGF-β1. The three borneol products had a tendency to reduce the body temperature of rats 1 day after modeling. Synthetic borneol at the doses of 0.2 and 0.05 g·kg~(-1), as well as L-borneol of 0.1 g·kg~(-1), significantly reduced Zea-Longa score and mNSS. The three borneol products at the dose of 0.2 g·kg~(-1) significantly reduced the cerebral infarction rate. L-borneol at the doses of 0.2 and 0.1 g·kg~(-1) and natural borneol at the dose of 0.1 g·kg~(-1) significantly reduced the pathological damage of the cortex. L-borneol and natural borneol at the dose of 0.1 g·kg~(-1) attenuated the pathological damage of hippocampus, and 0.2 g·kg~(-1) L-borneol attenuated the damage of striatum. The 0.2 g·kg~(-1) L-borneol and the three doses of natural borneol and synthetic borneol significantly reduced the serum level of TNF-α, and the 0.1 g·kg~(-1) synthetic borneol reduced the level of IL-6. L-borneol and synthetic borneol at the dose of 0.2 g·kg~(-1) significantly inhibited the activation of cortical microglia, and 0.2 g·kg~(-1) L-borneol up-regulated the expression of Arg1 and down-regulated the expression level of iNOS. In conclusion, the three borneol products may alleviate inflammation to ameliorate the pathological damage of brain regions of rats in the acute phase of I/R by inhibiting the activation of microglia and promoting the polarization of microglia from M1 type to M2 type. The protective effect on brain followed a trend of L-borneol > synthetic borneol > natural borneol. We suggest L-borneol the first choice for the treatment of I/R in the acute phase.

Abstract: The demand for reliable toxicological data of chemicals runs through every link of occupational health work. The prevention of occupational diseases involves high requirements for the standardization of chemical toxicity assessment in occupational health institutions. Good laboratory practice (GLP) emphasizes the integrity of the test process to trace and supervise the whole process of the test, which is conducive to the standardization of chemical toxicity identification. Therefore, the standardized construction of GLP laboratories is an important starting point for occupational health institutions to carry out chemical toxicity identification. In the construction and management process of GLP laboratories for chemical toxicity identification, occupational health institutions need to build a sound organization and operation system, carry out systematic training and assessment of personnel, establish standard operating norms and emphasize their importance, strengthen the management of facility environment and laboratory, pay attention to quality control and process supervision, and constantly improve their own ability level. To actively adapt to social development and market demand, to provide strong support for occupational health work.

Objective: To investigate the independent and joint effects of chronotype and sleep duration on self-rated health in medical students. Methods: A cross-sectional study was conducted in 1 526 medical students selected through proportional stratified cluster random sampling from a medical university in Zhejiang province. A questionnaire survey was conducted to collect the information about their basic demographic characteristics, chronotype, sleep duration, and other lifestyle factors such as midnight snack, sedentary behavior, physical activity, meal time, and self-rated health. The independent and joint effects of chronotype and sleep duration on self-rated health were assessed by logistic regression model after controlling for confounding variables. Results: The numbers of the students with evening chronotype, neutral chronotype, and morning chronotype were 664 (43.5%), 442 (29.0%), and 420 (27.5%), respectively. Among the medical students, 42.8% (653) had poor self-rated health. Compared with those with the morning chronotype, the adjusted ORs for those with neutral chronotype and evening chronotype were 1.69 (95%CI: 1.23-2.31) and 2.43 (95%CI: 1.81-3.26), respectively, trend test P<0.001. Compared with those with sleep duration of 8 h or above per night, the adjusted ORs for those with sleep duration of 7 and ≤6 h per night were 1.40 (95%CI: 1.07-1.84) and 2.38 (95%CI: 1.69-3.37), respectively, trend test P<0.001. In the joint effect, compared with those with the morning chronotype and sleep duration of 8 h or above per night, the adjusted OR for those with evening chronotype and sleep duration of ≤6 h per night was 6.53 (95%CI: 3.53-12.09). Conclusions: Both evening chronotype and insufficient sleep were associated with increased odds of poor self-rated health in medical students, and they had joint effects. Therefore, it is necessary to promote early to bed, early to rise and adequate sleep in medical student to maintain their health.

Objective:To observe the effects of ultrashort wave (USW) on lipopolysaccharide (LPS) induced acute lung injury (ALI) and nucleotide-binding oligomerization domain like receptor protein 3 (NLRP3) signaling pathway in rats. Methods:Twenty-four three-month-old male Sprague-Dawley rats were randomly divided into control group (n = 8), ALI group (n = 8) and USW group (n = 8). The ALI and USW groups were instilled with LPS to induce ALI, and the USW group was treated with ultrashort wave 0, four and eight hours after instillation, 15 minutes a time. Twenty-four hours after instillation, the lung tissue of the rats was measured the wet/dry mass ratio (W/D), and observed under HE staining. Serum levels of interleukin (IL)-1β and IL-18 were detected with ELISA. The mRNA and protein expression of NLRP3, caspase-1 and IL-1β in the lung tissue were detected with reverse transcription polymerase chain reaction and Western blotting, respectively. Results:W/D increased in ALI group compared with that of the control group (P < 0.05), and it decreased in USW group without significance compared with that of ALI group (P > 0.05). Lung injury score increased in ALI group compared with that of the control group (P < 0.05), and it decreased in USW group compared with that of ALI group (P < 0.05); as well as the serum IL-1β and IL-18, and mRNA and protein expression of NLRP3, caspase-1 and IL-1β. Conclusion:USW can alleviate the inflammatory of acute lung injury, which may associate with inhibiting of NLRP3 signaling pathway.

The internationally-accepted Consolidated Standards for Reporting of Trials (CONSORT) and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) were applied to evaluate the literature quality of randomized controlled trials (RCTs) regarding acupuncture for chronic neck pain in past 10 years. The literature of RCTs regarding acupuncture for chronic neck pain was searched by computer; the English literature was searched in PubMed and EMbase, while the Chinese literature was searched in CNKI, Wanfang database, VIP database and China Biomedical Literature Database. The literature published from January 2008 to January 2018 was searched. As a result, 29 Chinese articles and 10 English articles were included. According to CONSORT, among Chinese articles, 28 articles (96.6%) described baseline data, 23 articles (79.3%) described randomization, 0 articles (0.0%) described allocation concealment, 3 articles (10.3%) described blind method; among English articles, 6 articles (60.0%) described baseline data, 8 articles (80.0%) described randomization, 8 articles (80.0%) described allocation concealment, and 7 articles (70.0%) described blind method. According to STRICTA, among Chinese articles, 8 articles (27.6%) described needle instrument selection, 18 articles (62.1%) described needle depth, 24 articles (82.8%) described needling sensation, and 0 articles (0.0%) described acupuncturist' qualifications; among English articles, 5 articles (50.0%) described needle instrument selection, 8 articles (80.0%) described needle depth, 3 articles (30.0%) described needling sensation, and 4 articles (40.0%) described acupuncturist' qualifications. In conclusion, the reporting of acupuncture details in Chinese literature is superior to that in English literature, while the reporting of trial design in English literature is slightly superior to that in Chinese literature. Moreover, both Chinese and English literature need to further improve clinical trial design to improve the reporting quality of clinical evidence based on CONSORT and STRICTA.

Norovirus (NoV) is a pathogen that commonly causes viral diarrhea in children. Studies indicate that NoV recognizes human histo-blood group antigens (HBGAs) as cell attachment factors. In order to explore the correlation between of NoV infection and HBGAs, a cross-sectional study was conducted in children less than five years old who were hospitalized with diarrhea in two areas of China between November 2014 and February 2015. Of the paired stool and saliva samples taken from 424 children, NoV was detected in 24 (6%) children, with viral genotypes GII.3 (n=5), GII.4 (n=14), GII.12 (n=1), and GII.17 (n=4). All of the individuals having NoV infection were either secretors (Lea-b+/Lex-y+) or partial secretors (Lea+b+/Lex+y+) except one GII.3 infection of a non-secretor (Lea+b-/Lex+y-). These results suggest that secretor positive is associated with NoV infection, although non-secretors are not absolutely protected from NoV infection.

Objective To know the situation of postoperative pain and the satisfaction with pain management in patients who suffered osteonecrosis of the femoral head ( ONFH ) and accepted free vascularized fibular grafting ( FVFG ) , and analyze the influencing factors of satisfaction with pain management. Methods By convenience sampling method, 140 inpatients who underwent FVFG for 72 hours were recruited in this study. These patients were admitted in the orthopedic department of the Sixth People′s Hospital of Shanghai from January to October 2016, and were investigated by the general information questionnaire, the brief pain inventory, and the pain treatment satisfaction scale. The influencing factors of satisfaction with pain nursing were analyzed. Results The score of the most severe pain intensity of the 140 patients reached ( 4. 92 ± 1. 36 ) . The total score of patients′ satisfaction with pain management was (81. 81±9.09), among which, the dimension of professional skills earned the highest average score of (4.00± 0.61), followed by the dimension of trust, which was up to (3. 90±0.53). The dimension of the relation of education got the lowest score of (3.77±0.30). The analysis of single factor showed that the age and the education levels affected the satisfaction of pain management ( P<0. 05 ) . The stepwise multiple regression analysis reviewed that there were five factors having influences on the satisfaction of pain management, and they were: the most severe pain intensity after FVFG, the influences of pain on functional exercise, the degree of pain relief, the education level of patients, and the influences of pain on patients′sleeping. These can successfully explain 70.8% of the variation of the satisfaction ( R2=0.708) . Conclusions Patients are overall satisfied with postoperative pain treatment. Factors such as the most severe pain intensity after FVFG, the influences of pain on functional exercise, the degree of pain relief, the education level of patients, and the influences of pain on patients′sleeping will affect the degree of satisfaction.

The main factors which affected the isolation, purification and cultivation of Pinellia cordata protoplasts from leaves were studied. The results indicated that the optimum enzyme solution for P. cordata leaves was 13% CPW + 1.0% Cellulose +0.1% Pectolase, at pH 6.0, temperature (25-28 degrees C ) for 4 h. The sucrose density gradient centrifugation was adopted to purificate the protoplasts collected, when 25% sucrose was used as mediator, centrifugating at 500 rpm for 10 min. When the protoplasts were shallow liquid and liquid-solid double layer cultured on the medium of MS + 0.5 mg x L(-1) 6-BA + 0.25 mg x L(-1) NAA + 13% mannitol at the density of 2.5 x 104 protoplasts/mL, or fed and nursed cultured at the density of 100-500 protoplasts/mL, cell division could be observed for 3 days; granular calli appeared for 30 days. Calli was proliferated on the medium of MS + 0.5 mg x L(-1) 6-BA + 0.25 mg x L(-1) NAA solidified by 0.55% agar, and differentiated and regenerated after 5-6 months. Plant generation of P. cordata is successfully established.
