【Objective】 To study the effects of gestational diabetes (GDM) on morphological structure of brain tissue and microribonucleotide (miRNA) expression profile in neonatal mice, and to provide a new research target for the prevention and treatment of abnormal neurodevelopment in GDM progeny. 【Methods】 The pregnant mice were divided into model group and control group,each group consisted of 10 mice. The model group mice established a GDM model by injecting streptozotocin to measure fasting blood glucose (FPG) and random blood glucose (GLU) at different times. Successful molded mice were randomly divided into model group A and model group C, and control mice were divided into control group B and control group D, with 5 mice in each group. The newborn mice in groups A and B were used for hippocampal tissue GeneChip detection and brain morphology structure observation, and group C and D newborn mice were used for qRT-PCR detection of hippocampus tissue expression differences to verify the differentially expressed genes of miRANs obtained by GeneChip screening. After giving birth, the neonatal mice were sacrificed by decapitation, and the brain tissue was dissected to observe the overall morphological structure. The structural changes of hippocampus were observed under HE chromogenic microscope. The Agilent mouse miRNA oligonucleotide gene chip was used to detect the miRNA expression profile of mouse hippocampus, screen differential miRNAs and predict their target genes, and conduct GO analysis and signal transduction pathway analysis of target genes. The relative expression levels of the screened miRNAs were verified by qRT-PCR. 【Results】 Compared with the control group, the GLU increased significantly from the 3rd day after drug administration in the model group (P<0.01). Macroscopic observation of control group B mice had normal brain morphology and structure, smooth appearance, clear gyrus, close arrangement of hippocampus cell structure, uniform staining and complete structure; in model group A, the number of hippocampus cells decreased, loose arrangement and deep staining. In the initial screen of miRNA microarray, there were 11 differentially expressed miRNAs between control and model groups, all of which were downregulated miRNAs, including let-7b-5p、miR-130b-3p、miR-181c-5p、miR-181d-5p、miR-3099-3p、miR-3470a、miR-3473a、miR-3473b、miR-500-3p、miR-532-5p、miR-7047-5p(P<0.05). Two miRNAs (miR-3473b, miR-7047-75p) and 5 target genes (MAPK3, MAPK11, MAPK14, CALM3, AKT3). The relative expression of miR-3473b and miR-7047-5p in model group C were lower than that in control group D (t=19.13 and 6.24, P<0.05), and the validation results were consistent with the microarray test results. 【Conclusion】 Compared with the offspring of normal pregnant mice, GDM offspring mice have abnormal development of brain structure and damage of hippocampal nerve cells, and there are a large number of abnormal expression of miRNAs in hippocampal tissue. Differentially expressed miRNAs can be used as research targets for prevention and treatment of GDM offspring neurodevelopmental abnormalities.

OBJECTIVE To establish high performance liquid chromatography (HPLC) fingerprint of Xiaohe syrup and determine the contents of 10 effective ingredients in them. METHODS With 12 batches of Xiaohe syrup as samples, ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was adopted with Athena C18 (250 mm×4.6 mm, 5 μm) as the chromatographic column, acetonitrile-0.1% phosphoric acid aqueous solution as mobile phase for gradient elution. The flow rate was 1.0 mL/min, and the detection wavelength was 210 nm. Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprint (2012A version) was imported to establish the fingerprint of Xiaohe syrup and evaluate the similarity. The content determination was performed on ACQUITY UPLC BEH C18( 100 mm×2.1 mm, 1.7 μm) chromatographic column, with 0.01% formic acid acetonitrile-0.01% formic acid water as mobile phase for gradient elution at a flow rate of 0.4 mL/min; combined with high-resolution mass spectrometer, positive and negative ions were scanned with an electric spray ion source to determine the content of each main component in 12 batches of Xiaohe syrup. RESULTS A total of 33 common peaks were calibrated in 12 batches of samples, with similarities greater than 0.97; 10 chromatographic peaks were confirmed, namely flavonoid glycosides, paeoniflorin, ferulic acid, naringin, rosmarinic acid, neohesperidin, salvianolic acid B, tetrahydropalmatine, saikosaponin A, and saikosaponin D. The results of content determination showed that the above 10 components had good linear relationships within their respective mass concentration ranges (all R 2>0.999), with contents ranging from 0.35 to 0.64, 3.15 to 5.61, 0.11 to 0.17, 1.68 to 3.17, 1.59 to 1.90, 1.15 to 1.64, 0.78 to 1.48, 0.11 to 0.26, 0.06 to 0.13, and 0.33 to 0.61 mg/mL, respectively. CONCLUSIONS The main components of 12 batches of Xiaohe syrup are similar, but the contents vary; HPLC fingerprint and UPLC-MS/MS content determination method established in this study can be used for comprehensive quality evaluation of Xiaohe syrup.

Objective:
To evaluate the preventive effect of implementing the free influenza vaccination policy on school absence among primary and secondary school students, so as to provide a reference for formulating and adjusting vaccination strategies.
Methods:
Among primary and secondary school students aged 6 to 18 in Longgang District, Shenzhen, they were divided into a vaccinated group (265 996 students) and an unvaccinated group (122 513 students) according to their influenza vaccination history during November 2023. Propensity score matching was used to conduct a 1∶1 match between the two groups to balance covariates. The number of absences per month was set as the dependent variable to construct a difference in differences model, and Poisson regression was employed to analyze the overall and multi time point effects.
Results:
Vaccination against influenza was associated with low rate of absenteeism among primary and secondary school students, with an overall preventive effect of 26.52% (95% CI = 23.47% -29.45%). The preventive effects in November (the month of vaccination) and December 2023, January and March 2024 were 42.12%, 40.12%, 30.33% and 20.91%, respectively. The preventive effect of the influenza vaccine on absenteeism among primary school students (26.39%) was not significantly different from that among secondary school students ( 27.97% ) ( P >0.05). The regression coefficient for class vaccination rates ranged from 0.998 to 0.999 ( P <0.01), indicating that for every 10% increase in influenza vaccination rates, absenteeism could be reduced by 1.5% to 2.2%.
Conclusion
Implementing free influenza vaccination for primary and secondary school students might help to reduce the risk of absenteeism, yielding significant socioeconomic benefits.

Recent studies on male infertility reveal a growing worry: more infertile men are dealing with inflammation in the testis. Analyzing testicular biopsies from infertile men highlights a significant presence of inflammation. This connection, supported by clinical and pathological evidence, emphasizes that testicular inflammation hampers sperm production, leading to lasting declines in sperm count and quality. However, the exact reasons behind male infertility due to orchitis, a type of testicular inflammation, are still uncertain. Understanding these fundamental aspects of molecular signals and cellular mechanisms in testicular inflammation is crucial. Our review delves into recent literature with a dual objective: elucidating potential mechanisms involving immune cells, non-immune cells, and cytokines that link orchitis to male infertility, while also paving the way for precise interventions and solutions to address the challenges of male infertility.

OBJECTIVE To construct the quantitative evaluation system of regional clinical pharmacists’ professional ability, and provide reference for the evaluation of regional clinical pharmacists’ professional ability. METHODS Twenty-one experts from 18 hospitals in Chongqing were consulted to construct a professional ability index system for clinical pharmacists. TOPSIS model was used to calculate and obtain the expert authority index (EI), and the weighted averaging method was used to construct the judgment matrix. Analytic hierarchy process (AHP) was used to calculate the weights of all indicators for establishing a quantitative evaluation system of regional clinical pharmacists’ professional ability according to the weights of each item. RESULTS The results of TOPSIS showed that the EI range was 0.010-0.100, and the relative authority of experts was distinguished and measured effectively. The results of AHP showed that the judgment matrix of the quantitative evaluation system met the requirements of consistency test (consistency test index CR<0.1). Finally, a quantitative evaluation system for regional clinical pharmacists’ professional ability was established, including 6 sub-objective items (basic ability, clinical practice ability, coordination and communication ability, publicity ability, scientific research and teaching ability, continuous improvement ability) and 25 index items (such as educational background, professional title, clinical pharmacy working years, daily theoretical skills assessment, information ability level, medication education, etc.). CONCLUSIONS A quantitative evaluation system of regional clinical pharmacists’ professional ability has been established. Our study provides a theoretical reference for the quantitative evaluation and optimal management of regional clinical pharmacists.
