Objective To systematically evaluate the correlation between vitamin D deficiency in early pregnancy and the outcome of preterm birth.Method PubMed,Embase,the Cochrane Library,Web of Science,Ebsco,CBM,CNKI and Wanfang Data databases were searched to collect cohort studies and case-control studies on the correlation between vitamin D deficiency in early pregnancy and preterm birth outcomes,and the retrieval time was from the establishment of the database to June 2019.Two researchers independently reviewed the literature,extracted the data and evaluated the risk of bias in the included studies.RevMan 5.3 software was used for Meta analysis.Result A total of 6 cohort studies and 3 nested case-control studies were included.A total of 30 891 newborns were included,including 1 912 premature infants.3 Chinese articles and 6 English articles were reviewed including three studies from China,three from North America,two from Europe and one from Australia.The diagnostic criteria for vitamin D deficiency and preterm birth were similar in these studies.After adjusting for age,race and other confounding factors,Meta-analysis results showed that vitamin D deficiency in early pregnancy did not increase the risk of preterm birth (OR =1.04,95％ CI 0.90 ～ 1.20,P =0.63).Subgroup analysis were conducted according to the study type,measurement method and regional population,and the results were consistent with the overall results.No significant publication bias was found in the meta-analysis results.Conclusion Current evidence suggests that vitamin D deficiency in early pregnancy has no significant influence on preterm birth.

Objective:To investigate the relationship between electrocardiographic (ECG) changes and prognosis of paraquat poisoning patients, so as to provide evidence for the condition assessment in paraquat poisoning patients.Methods:In January 2022, The clinical data of paraquat poisoning patients were retrospectively analyzed in the First Affiliated Hospital of Wenzhou Medical University from January 1, 2016 to December 31, 2021. The patients' basic information (age, sex, underlying disease, and occupation) and the ECG within 24 hours were collected, and the data were statistically analyzed by SPSS 22.0. One variable analysis and multivariable logistic regression analysis were used to analyze the risk factors related to prognosis determine in their ECG. The receiver operating characteristic (ROC) curve were used to evaluate the diagnostic value of ECG indexes in patients with paraquat poisoning.Results:A total of 145 patients with paraquat poisoning were finally enrolled in this study, there were 84 patients survived and 60 patients died. One variable analysis revealed that heart rate ( P=0.000) , QTc changes ( P=0.000) , and ST-T changes ( P=0.007) of ECG had statistically significant differences in the prognosis of paraquat poisoning patients between the survival group and the death group. Multifactorial logistic results showed that heart rate ( OR=1.059, 95% CI: 1.033~1.086) and QTc ( OR=1.015, 95% CI: 1.000~1.029) were independent risk factors for death diagnosis of patients with paraquat poisoning ( P<0.05) . ROC curve analysis revealed that the area under the cure (AUC) of the prediction model constructed based on heart rate and QTc was 0.832 (95% CI: 0.765~0.899) , with the best diagnostic efficacy. Conclusion:Heart rate, QTc and the prediction model constructed based on both can be used as prognostic indicators for the diagnosis of patients with paraquat poisoning, and which have reference value for clinical prognosis diagnosis.

Objective:To study the effects of Terra Flavausta on diarrhea mice with spleen yang deficiency based on metabonomics. Methods:Totally 30 mice were divided into normal group, model group and Terra Flavausta group according to random number table method. Mice in the model group and Terra Flavausta group were treated by the method of "diet disorder + clearing fire with herbs bitter in flavour and cold in property" to establish the diarrhea model of spleen yang deficiency. After successful modeling, Terra Flavausta group received Zaoxintu Decoction 12.0 g/kg for gavage, while normal group and model group were given equal volume of distilled water for gavage, for consecutive 7 d. The serum metabolites of each mouse were analyzed and identified based on UPLC-Q-Exective-MS. The differential metabolites were characterized by principal component analysis and orthogonal partial least squares discriminant analysis, and the potential biomakers were screened, and the KEGG pathway enrichment analysis was performed. Results:Totally 110 different metabolites were screened under the positive and negative ion mode. Terra Flavausta can effectively reverse the disorder of serum metabolism in diarrhea mice with spleen yang deficiency, and has a significant callback effect on 12 potential biomarkers related to diarrhea with spleen yang deficiency. KEGG pathway enrichment mainly involved HIF-1 signaling pathway, ascorbate and aldarate metabolism, platelet activation, etc. Conclusion:Terra Flavausta may play the effect of warming spleen and relieving diarrhea through down-regulation of L-ascorbic acid affecting HIF-1 signal pathway, ascorbic acid and aldose metabolism pathway, vitamin digestion and absorption pathway, up-regulation of prostaglandins G2 and H2 affecting platelet activation pathway, and down-regulation of jasmonic acid α linolenic acid metabolic pathway.

The pharmacokinetic profile of gallocatechin-7-gallate (J10688) was studied in rats after intravenous administration. Male and female Sprague-Dawley (SD) rats received 1, 3, and 10 mg/kg (i.v.) of J10688 and plasma drug concentrations were determined by a high performance liquid chromatography-mass spectrometry (LC-MS) method. The pharmacokinetic software Data Analysis System (Version 3.0) was used to calculate the pharmacokinetic parameters. For different i.v. doses of J10688, the mean peak plasma concentration (C 0) values ranged from 11.26 to 50.82 mg/L, and mean area under the concentration-time curve (AUC0-t ) values ranged from 1.75 to 11.80 (mg·h/L). J10688 lacked dose-dependent pharmacokinetic properties within doses between 1 and 10 mg/kg, based on the power model. The method developed in this study was sensitive, precise, and stable. The pharmacokinetic properties of J10688 in SD rats were shown to have rapid distribution and clearance values. These pharmacokinetic results may contribute to an improved understanding of the pharmacological actions of J10688.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Objective To construct intrauterine adhesion (IUA) mouse models induced by two different concentrations of ethanol injury, compare the phenotypes, and optimize a more stable IUA modeling method. Methods Twenty 8-week-old female C57BL/6N mice were randomly divided into two groups: the 95% ethanol injury group and the 50% ethanol injury group. Using a self-control method, the left uterine horn was infused with ethanol to establish the IUA model, while the right uterine horn was infused with saline as the sham operation. Five mice from each group were euthanized on day 7 and 15 after modeling, and uterine tissues were collected. Hematoxylin-eosin (HE) staining was used to observe the endometrial pathology, and Masson staining was used to assess the degree of endometrial fibrosis. Quantitative real-time PCR was employed to detect the expression levels of fibrosis markers and pro-inflammatory factors in the uterine tissues. Results Compared to the sham operation, these two ethanol injury led to a significant reduction in elasticity of the uterus, an increase in inflammatory infiltration, and a marked increase in the degree of fibrosis on day 7 after modeling (P<0.05). The 95% ethanol injury group showed a significant decrease in endometrial thickness (P<0.05), whereas no significant change was observed in the 50% ethanol injury group when compared to the sham operation (P>0.05). The expression levels of fibrotic marker molecules collagen type Ⅳ alpha 1 chain (Col4A1), α-smooth muscle actin (α-SMA), transforming growth factor-β (TGF-β), and pro-inflammatory factors tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were significantly elevated in the 50% ethanol injury group when compared to the sham operation (P<0.05), although there was an increasing trend of the same markers in the 95% ethanol injury group, the differences were not statistically significant (P>0.05). On day 15 after modeling, the histopathological changes in both ethanol injury groups were not significant when compared to the sham operation, the expression levels of Col4A1, TGF-β, TNF-α and IL-1β remained significantly higher in the 50% ethanol injury group (P<0.05), while only IL-1β was significantly elevated in the 95% ethanol injury group (P<0.05). Conclusion Uterine infusion with 95% ethanol results in more marked histopathological changes in the IUA mouse model compared to the 50% ethanol injury group. The 95% ethanol injury model is suitable for histopathological studies. However, the 50% ethanol injury group shows higher expression levels of fibrosis markers and pro-inflammatory factors compared to the 95% ethanol injury group, suggesting that the 50% ethanol injury model is more suitable for molecular pathological study.
