Objective Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)and network pharmacology technology combined with pharmacodynamic experiments were used to analyze the quality markers(Q-markers)in Saorilao Qingfei Zhike Capsules.Methods Using UPLC-Q-TOF-MS technology,the chemical components in different polar extracts of Saorilao Qingfei Zhike Capsules was analyzed.Potential pharmacological components were screened by using antitussive and expectorant models.The"components-targets-diseases"network was constructed and potential Q-markers were screened by network pharmacology technology.Then we conducted pharmacodynamic validation to confirm the Q-markers,which have antitussive and expectorant effects in Saorilao Qingfei Zhike Capsules.Results A total of 120 compounds were obtained from the Saorilao Qingfei Zhike Capsules through qualitative analysis.Among the extracts of different polarity,44 compounds were derived from petroleum ether extract,85 compounds were derived from ethyl acetate extract,79 compounds were derived from n-butanol extract,and 71 compounds were derived from water extract.The results of pharmacological experiments showed that among extracts of different polarity,petroleum ether extract had the best antitussive effect,while n-butanol extract had the best expectorant effect.Three core components for eliminating phlegm and relieving cough were screened through network pharmacology techniques:farcalinol,farcalinediol,and rubimaillin.Pharmacodynamic studies verified that all core components mentioned above have certain antitussive and expectorant effects.Conclusion Based on the above research,farcalinol,farcalindiol,and rubimaillin can be used as Q-markers for the antitussive and expectorant effects of Saorilao Qingfei Zhike Capsules.This paper provides reference for the quality standard of Saorilao Qingfei Zhike Capsules.

Objective:This study aims to explore the synergistic effects of DIP and other medical insurance supply-side policies.Method:City A that has piloted DIP reform was set as the treatment group,and City B without reform was set as the control group.A total of 1 120 public medical institution samples from 2019 to 2022 were collected.The total medical expenses during hospitalization and some structural expenses were analyzed using DID method.Result:DIP had a significant inhibitory effect on the medical expenses,and the expenses of checkups and examinations during hospitalization in city A,but had no impact on the drug and the material expenses during hospitalization.Conclusion:DIP played a significant cost control role and effectively controlled the total medical expenses during hospitalization.The synergistic effects of price adjustment of medical services policy and national centralized drug/material procurement policy on cost control were insufficient.DIP synergized with other supply-side policies to promote rational medical cost structure.It is suggested that medical insurance departments should focus on the synergistic effects of medical insurance supply-side policies to jointly improve the efficiency of medical insurance fund utilization.

OBJECTIVE: To study the clinical features of children with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome, a polygenic and multifactorial autoinflammatory disease with unknown pathogenesis. METHODS: A retrospective analysis was performed on the medical data of 13 children with PFAPA syndrome. RESULTS: All 13 children had disease onset within the age of 3 years, with a mean age of onset of (14±10) months. They all had periodic fever, with 8-18 attacks each year. The mean interictal period of fever was (30±5) days. Pharyngitis, cervical adenitis, and aphthous stomatitis were the three cardinal symptoms, with incidence rates of 100% (13/13), 85% (11/13), and 38% (5/13) respectively. There were increases in white blood cells, C-reactive protein, and erythrocyte sedimentation rate during fever. Of all the 13 children, 6 underwent whole exome sequencing and 7 underwent panel gene detection for autoinflammatory disease, and the results showed single heterozygous mutations in the CONCLUSIONS For children with unexplained periodic fever with early onset accompanied by pharyngitis, cervical adenitis, aphthous stomatitis, elevated inflammatory indices, and good response to glucocorticoids, PFAPA syndrome should be considered. This disorder has good prognosis, and early diagnosis can avoid the long-term repeated use of antibiotics.

Objective To explore the relationships between advanced puberty timing and frequencies of problem behaviors using two different indexes of pubertal development as cut-off standards. Methods A total of 3003 primary school girls aged 6~11 in Beijing were recruited in the study. Parent-assessed Tanner staging according to the menarche and pubic hair development level and the Achenbach Child Behavior Checklist were applied. Results When timing of menarche and pubic hair development stage were used as reference, the detection rate of girls with advanced puberty timing was 11.2% (337/3003) and 3.4% (101/3003), respectively. The scores of withdrawal problem (Z=-2.23, P=0.03) and physical problem (Z=-2.64, P=0.01) were higher in the advanced menarche group than in the moderate group. The scores of withdrawal behavior problem were higher in the advanced pubic hair development group than in the moderate group (X2=2.53, P=0.03). Scores of social problem (X2=2.71, P=0.02), aggression problem (X2=2.50, P=0.04), total score of problem behavior (X2=2.64, P=0.03) were also higher in the advanced pubic hair development group than in the delayed group. The correlation between the pubertal timing results based on the two different cut-off standards was not significant (r=0.04, P=0.06). Conclusion T he detection rate of girls with advanced puberty timing are different using the two different cut-off standards. The prominent problem behaviors in the advanced group are also different. Compared with girls with advanced menarche, girls with advanced pubic hair development may have more prominent problem behaviors than those with moderate development.

Objective: To investigate the relationships between behavioral problems and family environment in obese children aged 6-15 years to provide a dereference for the analysis of behavioral problems among obese children and the construction of their family environmet . Methods: Family environment dimensions and behavioral problems were investigated among 2 376 obese children and 2 376 non-obese children with Family Environment Scale Symptoms Questionnaire and Achenbach Child Behavior Checklist. Data were analyzed by SPSS 17.0. Results: The incidence of the behavioral problems in obese children (21.12%) was higher than that of non-obese children (15.53%)(χ2=24.93，P<0.01).The scores of Family Environment Scale Symptoms Questionnaire differed between obese children and nonobese children (Z=-2.44, -2.98, -3.38, P<0.05). Binary logistic regression results showed that for obese boys and girls aged 6 to 11 years, high maternal education levels(OR=0.78, 95%CI=0.69-0.88), family cohesion(OR=0.75, 95%CI=0.67-0.84) and less family conflicts(OR=0.81, 95%CI=0.75-0.87) were related to less behavioral problems; for obese boys and girls aged 12 to 15 years, family cohesion(OR=0.79, 95%CI=0.70-0.90) and less family conflicts(OR=0.78, 95%CI=0.71-0.86) were related to less behavioral problems. Conclusion Family cohesion and less family conflicts might help low the risk of behavioral problems among obese children. The role of family environment on behavioral problems should not be neglected in future mental health promotion and social work service for obese children.

The present study aims to analyze sperm concentration trends among young and healthy Chinese adults in Wuhan, Central China, from 2010 to 2015. Semen analysis data from 9357 participants were collected and analyzed using a general linear model and the Cochran-Armitage trend test. A significant decline was observed in sperm concentration (β [standard deviation]: -1.53 [0.16]; P < 0.001). In addition, a decline in sperm density was observed by stratifying student versus nonstudent sperm donors and by analyzing the year of birth or birth year cohort of the participants. Furthermore, the percentage of participants with sperm densities of over 40 × 10⁶ ml^-1 significantly decreased with year. Notably, a dramatic decline in sperm density was recorded over the first 5 years of study. This research reported a decline in sperm concentration among young adults in Wuhan, Central China, in 2010-2015.

OBJECTIVETo observe the effects of deguelin on the proliferation of breast cancer MCF-7 cells and lung cancer H1299 cells in vitro and the expression of minichromosome maintenance protein 3 (MCM3) and CDC45 in the cells.

METHODSMTT assay was used to evaluate the proliferation of MCF-7 and H1299 cells exposed to different concentrations of deguelin for 48, 72 or 96 h. The growth of the cells was observed microscopically and the changes of MCM3 and CDC45 expressions in MCF-7 and H1299 cells following deguelin treatment were detected with fluorescence quantitative PCR.

RESULTSThe proliferation of MCF-7 cells was significantly inhibited by exposure to 0.25, 0.5, 1, 5, 10, 30, and 50 µmol/L deguelin for 48, 72, and 96 h in a concentration- and time-dependent manner. In MCF-7 cells, the ICof deguelin at 48, 72, and 96 h was 9, 3, and 2 µmol/L, respectively. Deguelin treatments of H1299 cells at 0.5, 1, 5, 10, 30, 50, and 100 µmol/L also resulted in a concentration- and time-dependent inhibition of the cell growth with an ICat 96 h of 2 µmol/L. Optical microscopy of the cells revealed a decreased number of viable cells with obvious cell shrinkage following deguelin treatments. The expression of MCM3 and CDC45 were significantly reduced in the cells after deguelin treatments.

CONCLUSIONDeguelin can inhibit the proliferation of MCF-7 and H1299 cells in vitro and down-regulate the expression of MCM3 and CDC45 in the cells.

The present study was conducted to clarify the psychophysiological relaxation effects of viewing bamboo on university students. Forty healthy Chinese participants enrolled in this study to clarify the psychophysiological relaxation effects of viewing bamboo. The effects of visual stimulation using a pot both with and without a bamboo were recorded by measuring the student's blood pressure, EEG and STAI. We observed that viewing bamboo plants resulted in significantly lower systolic (female, P < 0.001; male, P < 0.001; P < 0.05) and diastolic (female, P < 0.001; male, P < 0.001; P < 0.05) blood pressures, but no changes in the pulse rate (female, P = 0.09; male, P = 0.07; P > 0.05) were observed. The results of the EEG analysis indicated brainwave variation (all P < 0.05) and lower anxiety scores (P < 0.01) after 3 min of viewing bamboo compared with the control. These findings indicate that visual stimulation with bamboo plants induced psychophysiological relaxation effects on adults.
