ABSTRACT
ObjectiveTo investigate the prevalence of polycystic ovary syndrome （PCOS） among female college students at a university in Fuzhou City， Jiangxi Province， and to facilitate early detection and intervention of PCOS. MethodsUsing a stratified sampling method， a total of 450 female freshmen were randomly selected for PCOS screening. A self-designed questionnaire was used for data collection， covering menstrual status， high androgen signs， lifestyle， dietary habits， and awareness of PCOS. Sample t test and χ2 test were used to compare the basic information and dietary habits between PCOS and non-PCOS cases. The correlation between various indicators and the prevalence of PCOS was analyzed by a logistic regression model. ResultsA total of 12 PCOS cases were identified， with a prevalence rate of 2.99%. PCOS cases exhibited statistically significant differences compared to non-PCOS cases in terms of waist-to-hip ratio， waist circumference， abdominal obesity， the proportion of overweight or obese individuals， and a preference for sweet food （all P<0.05）. Multivariate logistic regression analysis revealed a significant correlation between preference for sweet food and the occurrence of PCOS （OR=4.858， 95%CI=1.199‒19.675，P=0.027）， as well as a significant correlation with PCOS accompanied by abdominal obesity （OR=7.083， 95%CI=0.773‒64.937， P=0.048）. Among the female college students surveyed， 37.90% had never heard of PCOS， 51.62% were only familiar with the name of the disease， and 10.47% had attempted to search for PCOS-related information. ConclusionThe prevalence of PCOS among female college students should not be overlooked and unhealthy dietary habits may be a crucial factor contributing to the occurrence of PCOS during this period. Early screening for PCOS during puberty is crucial.
ABSTRACT
Objective To explore the optimal concentration of Tanreqing injection for acute upper respiratory tract infections. Methods A retrospective analysis of 531 children with acute upper respiratory tract infection treated with Tanreqing injection was conducted. These children were divided into different groups according to concentration of Tanreqing injection (i.e., the relationship between liquid and solvent, or the dilution ratio of solvent to liquid). Assume that X was the dilution ratio of solvent to liquid and the group was divided by an additional increment of 2.5 dilution units. All the children were divided into six groups as follows, groups of A (1:10≤X<1:12.5), B (1:12.5≤X<1:15), C (1:15≤X<1:17.5), D (1:17.5≤X<1:20), E (1:20≤X<1:22.5) and F (1:22.5≤X<1:25). The clinical effective rate and incidence of adverse reactions in each group were used as clinical indicators related to concentration of Tanreqing injection. Origin 8 was used to establish the relationship between the two indicators and the median of the concentration, and to seek a net benefit index that can combine the two indicators together. Finally, the relationship between the net benefit indicator and the median of the concentration were established, and the optimal concentration was found by judging and picking up the maximum of the net benefit indicator. Results The relationship between the clinical effective rate and the concentration median were: Y=-0.3+31.58X-203.33X2 (R2=0.988 46), and relationship between the incidence of adverse reactions and the concentration median were: Y=-0.27+10.24X-67.85X2 (R2=0.982 28), and relationship between the net benefit indicator and the concentration median were: ΔY=-0.03+21.34X-135.48X2. The peak value of the net benefit indicator was 0.81, and the corresponding median of the concentration was 0.078 8, and the optimal dilution ratio of liquid to solvent was 1:11.6-1:14.1. Conclusions This article explored the optimum concentration range of Tanreqing injection and gave tips for clinical safety and effective drug use.

ABSTRACT
OBJECTIVE:To provide reference for clinical rational use of piperacillin sulbactam for the anti-infection of Pseudo-monas aeruginosa. METHODS:105 inpatients with normal liver and kidney functions that the pathogen was diagnosed as P. aerugi-nosa and susceptible to PIP/SBT from Jul. 2013 to Jun. 2014 were chose,dosing regimens were collected,the minimum inhibitory concentration (MIC) of piperacillin sulbactam for P. aeruginosa was 1 mg/L based on a one compartment pharmacokinetic mode, the standard value of the percentage of the duration of plasma concentration more than MIC(T>MIC)to dosing interval time was 45%,T>MIC was calculated with pharmacokinetic formula of both single dose and multiple dose repeated intravenous administra-tion to analyze the situation of reaching the standard of T>MIC;and the dosing interval time of the original scheme was prolonged appropriately to investigate the situation of reaching the standard of the percentage of (T>MIC) to dosing interval time. RE-SULTS:47 patients’dosing regimens were given 3.0 g PIP/SBT once every 8 hours,and the others were given 3.0 g PIP/SBT once every 12 hours;for P. aeruginosa,the percentages of T>MIC to dosing interval time were respectively 99.93% and 73.13% with pharmacokinetic formula of single dose intravenous administration,and 99.98%and 68.08%with pharmacokinetic formula of multi-ple dose repeated intravenous administration;and the percentages of the interval time prolonged to 16 h were respectively 54.84%and 51.06%,both reached the standard value. CONCLUSIONS:Quantitative analysis of PK/PD prediction parameters can be used to evaluate and optimize the clinical dosing regimens and guide the clinical practice.
