ObjectiveTo evaluate the clinical efficacy and safety of Wenshen Yangxue decoction combined with endometrial microstimulation in the treatment of infertile patients with polycystic ovary syndrome （PCOS， syndrome of kidney-Yang deficiency and blood stasis）. MethodsA randomized， positive-drug parallel-controlled， open-label clinical study was conducted. A total of 240 infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis who met the inclusion and exclusion criteria were randomly assigned into 4 groups， with 60 patients in each group. The control group was treated with clomiphene citrate （50-100 mg·d^-¹， orally for 5-10 consecutive days） for ovulation induction. On the basis of the therapy in the control group， the Wenshen group was additionally treated with Wenshen Yangxue decoction （250 mL， warm oral administration， twice daily， in the morning and evening）， and the stimulation group received endometrial microstimulation during the early follicular phase. The combined group was treated with clomiphene citrate plus Wenshen Yangxue decoction （at the same dosages as aforementioned） and endometrial microstimulation. The course of treatment for all the groups was 3 menstrual cycles. The pregnancy rate， ovulation status， sex hormone levels， glucose metabolism indicators， coagulation function， endometrial thickness， traditional Chinese medicine （TCM） symptom scores， and adverse reactions were observed in each group. ResultsA total of 239 patients were included in the final analysis， with 59 patients in the Wenshen group and 60 patients in each of the other three groups. The pregnancy rates were 43.3%（26/60） in the combined group and 32.2%（19/60） in the Wenshen group， both significantly higher than that （10%） in the control group （χ²=17.56，P<0.01）. Compared with the control group， the combined and Wenshen groups had increased mature follicle rates （P<0.01）， while the Wenshen group showed a decreased luteinization rate （P<0.05）. All the groups exhibited significant reductions in TCM symptom scores after treatment， and the Wenshen and combined groups had lower scores than the control group （P<0.01）. No statistically significant difference was found in the incidence of adverse events among the four groups， and all the adverse events were mild. ConclusionWenshen Yangxue decoction combined with endometrial microstimulation can alleviate the TCM symptoms of infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis， promote follicular maturation and ovulation， increase the cumulative pregnancy rate， and has good safety. It can provide new clinical evidence for the integrated traditional Chinese and Western medicine treatment of PCOS infertility.

[Objective] To study the molecular biological mechanism for a case of ABO blood group B subtype, and perform three-dimensional modeling of the mutant enzyme. [Methods] The ABO phenotype was identified by the tube method and microcolumn gel method; the ABO gene of the proband was detected by sequence-specific primer polymerase chain reaction (PCR-SSP), and the exon 6 and 7 of the ABO gene were sequenced and analyzed. Homologous modeling of Bw.03 glycosyltransferase (GT) was carried out by Modeller and analyzed by PyMOL2.5.0 software. [Results] The weakening B antigen was detected in the proband sample by forward typing, and anti-B antibody was detected by reverse typing. PCR-SSP detection showed B, O gene, and the sequencing results showed c.721 C>T mutation in exon 7 of the B gene, resulting in p. Arg 241 Trp. Compared with the wild type, the structure of Bw.03GT was partially changed, and the intermolecular force analysis showed that the original three hydrogen bonds at 241 position disappeared. [Conclusion] Blood group molecular biology examination is helpful for the accurate identification of ambiguous blood group. Homologous modeling more intuitively shows the key site for the weakening of Bw.03 GT activity. The intermolecular force analysis can explain the root cause of enzyme activity weakening.

[Objective] To investigate the factors associated with alanine aminotransferase (ALT) abnormalities in multi-ethnic blood donors across five Zang autonomous prefectures in the plateau regions of Qinghai Province, and to provide evidence for ensuring blood safety and formulating screening strategies. [Methods] A retrospective analysis was performed on the ALT abnormal test results of blood donors in the Zang autonomous prefectures of Qinghai from 2022 to 2024. The correlations between ALT levels and factors including gender, age, altitude, and infectious markers were investigated. [Results] The overall ALT unqualified rate among blood donors in this region was 9.01%. Significant differences in ALT levels were observed across genders and age groups (P<0.05). Variations in ALT abnormality rates were also noted among different plateau regions (P<0.05). Overall, ALT values exhibited an increasing trend with rising altitude. The average ALT unqualified rates were 11.19% in Zang donors, 7.96% in Han donors, and 4.79% in donors from other ethnic groups (P<0.05). No statistically significant association was observed between ALT abnormality and the presence of HBV/HCV infectious markers (P>0.05). [Conclusion] In the plateau areas of Qinghai, multi-ethnic blood donors have a relatively high ALT levels and ALT unqualified rates, showing distinct regional characteristics. ALT elevation in voluntary blood donors is related to non-pathological factors such as gender, age, and dietary habits, but not to infectious indicators.

Objective To establish a mouse model of H1N1 influenza wind-heat syndrome by combining climate intervention with influenza virus nasal drops.Methods Seventy-two BALB/c mice were divided randomly into nine groups:a Control group,wind-heat(FR)groups(FR-3Day,FR-5Day),and Model groups(1LD-3Day,2LD-3Day,3LD-3Day,1LD-5Day,2LD-5Day,2LD-5Day,3LD-5Day)(n=8 mice per group).Mice in the Control group were housed in a normal environment,while mice in the FR and Model groups were kept in wind-heat conditions for 7 d.Mice in the Model groups received nasal PR8 influenza virus infection on the 8th day,and mice in the Control and FR heat groups received equal amounts of physiological saline nasal drops.After virus challenge,each group was housed in a normal environment and samples were taken on days 3 and 5.The appearance of the mice was observed and recorded and the lung index,routine blood parameters,lung tissue pathology,serum interleukin(IL)-6 levels,and virus titers were detected in each group based on their behavioral status,stools,and body temperature.Results After 7 d of wind-heat intervention,mice in the FR groups showed no significant abnormalities in terms of appearance,stools,body temperature,routine blood parameters,or lung tissue pathology compared with the Control group.The appearance,lung index,red blood cell count,hemoglobin,hematocrit,pathological result,and body temperature in the Model groups worsened progressively with increasing time and toxin dosage,while the neutrophil percentage,lymphocyte percentage,virus titer,and serum IL-6 levels peaked on day 3 after viral attack,for the same viral dose,and then decreased slightly on day 5.Conclusions PR8 nasal drops and 7 d of wind-heat climate intervention can be used to establish a mouse model of influenza wind-heat syndrome.

Objective:To investigate the impact of day 3 embryo quality on pregnancy outcomes in frozen-thawed single blastocyst transfer cycles and analyze its value in embryo selection.Methods:A retrospective cohort study was conducted on clinical data from patients undergoing frozen-thawed single blastocyst transfer at the Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2020 to December 2023. A total of 4 691 cycles of high-quality day 3 embryo (H-D3) group and 2 598 cycles of low-quality day 3 embryo (L-D3) group in the same period were included. Multivariate logistic regression was used to analyze the effects of day 3 embryo quality on clinical pregnancy rate (CPR) and live birth rate (LBR). All the cycles were stratified according to developmental day and quality of blastocyst: 3 920 cycles of high-quality day 5 blastocysts (H-D5), 1 271 cycles of low-quality day 5 blastocysts (L-D5), 834 cycles of H-D6 group and 1 264 cycles of L-D6, the influence of day 3 embryo quality was subsequently analyzed under different conditions.Results:1) Significant differences were observed between H-D3 and L-D3 groups in female age [(31.79±4.42) years vs. (32.28±4.43) years, P<0.001], basal follicle-stimulating hormone levels [6.24 (5.32,7.35) U/L vs. 6.48 (5.42,7.62) U/L, P<0.001], proportion of primary infertility [35.86% (1 682/4 691) vs. 31.99% (831/2 598), P<0.001], proportion of ≥2 prior failed embryo transfer cycles [3.77% (177/4 691) vs. 5.93% (154/2 598), P<0.001], proportion of gonadotropin-releasing hormone agonist/antagonist controlled ovarian hyperstimulation protocol in fresh cycles [93.33% (4 378/4 691) vs. 89.80%(2 333/2 598), P<0.001], embryo cryopreservation duration [3.10 (2.23,7.27) months vs. 3.60 (2.30,15.40) months, P<0.001], proportion of day 5 blastocyst transfers [74.82% (3 510/4 691) vs. 64.70% (1 681/2 598), P<0.001] and proportion of high-quality blastocyst transfers [72.59% (3 405/4 691) vs. 51.92% (1 349/2 598), P<0.001]. No significant differences were found in body mass index, infertility duration, endometrial preparation program or endometrial thickness on transfer day (all P>0.05). 2) Multivariable logistic regression analysis demonstrated that the L-D3 group had significantly lower CPR ( OR=0.837, 95% CI: 0.754-0.929, P<0.001) and LBR ( OR=0.880, 95% CI: 0.794-0.974, P=0.014) compared with the H-D3 group. 3) In H-D5 and L-D5 cycles, L-D3 did not significantly affect CPR ( aOR=0.941, 95% CI: 0.805-1.101, P=0.449; aOR=0.910, 95% CI: 0.724-1.142, P=0.415) or LBR ( aOR=1.034, 95% CI: 0.893-1.196, P=0.657; aOR=0.917, 95% CI: 0.729-1.153, P=0.457). However, in D6-H and D6-L cycles, L-D3 significantly reduced CPR ( aOR=0.732, 95% CI: 0.542-0.987, P=0.041; aOR=0.648, 95% CI: 0.515-0.815, P<0.001) and LBR ( aOR=0.645, 95% CI: 0.479-0.869, P=0.004; aOR=0.670, 95% CI: 0.526-0.854, P=0.001). Conclusion:Day 3 embryo quality significantly impacts both CPR and LBR in frozen-thawed day 6 single blastocyst transfer cycles. This suggests that day 3 embryo quality retains clinical relevance as a selection criterion when prioritizing day 6 blastocysts for transfer.

Premature ovarian insufficiency(POI)is a disease that seriously affects the health and life of women,which is also one of the main causes of female infertility.The incidence of POI is increasing in recent years.The diagnostic criteria of POI are not uniform,and different diagnostic criteria have inconsistent thresholds for various indicators.Strict diagnostic criteria are more conducive to early detection and treatment of POI.At present,complementary and alternative therapies such as traditional Chinese medicine,acupuncture and moxibustion are widely used in the treatment of POI.This article reviewed the recent studies on the complementary and alternative therapy of traditional Chinese medicine in the treatment of POI,and finds that the dialectical treatment of traditional Chinese medicine is based on the perspective of traditional Chinese medicine theory and puts forward corresponding treatment plans for different dialectical types.For example,treatment from the kidney,tonifying kidney filling essence,regulating chongren;Treatment from the liver,soothing the liver,regulating qi,nourishing blood and softening the liver;Treatment from the heart and spleen,nourishing Yangming,tonifying the spleen and nourishing the heart.In terms of acupuncture treatment,regulating menstruation and promoting pregnancy and regulating the conception vessel and toning the governor vessel and toning the kidney are often used to treat POI.In addition,moxibustion regulates body function by stimulating the bladder meridian and conception vessel and governor vessel acupoints.Other methods,such as ear acupoint bean-pressing,acupoint thread-embedding and acupoint injection,have also shown potential in the treatment of POI.This article summarizes the role and characteristics of traditional Chinese medicine in the treatment of POI,in order to provide ideas and basis for clinical treatment of POI.

Objective To identify high-risk factors for healthcare-associated infection(HAI)in patients in inten-sive care units(ICUs),and develop a quick response(QR)code-based APP prediction tool.Methods Information of inpatients in general ICUs of three hospitals in Guizhou Province from January to December 2024 were collected.Risk factors were analyzed with a logistic regression model.QR code-based APP was constructed and validated.Results A total of 1 782 patients in general ICUs of three hospitals in Guizhou Province in 2024 were included in the analysis,out of which 410 were HAI cases,and the incidence of HAI was 23.01％.Multivariate logistic regre-ssion analysis results of HAI in ICU inpatients showed that regional gross domestic product(GDP)≥58 685 Yuan,performing pathogen culture during this hospitalization,history of diabetes mellitus,history of cancer,length of hospital stay ≥7 days before infection,and duration of persistent fever＞5 days before infection were independent risk factors for HAI in ICU patients(all P＜0.05).The discrimination of the model(area under the receiver operating characteristic curve[AUC]of 0.841),calibration(Brier score of 0.129),and clinical effectiveness(net benefit of 11.4％when the risk threshold was 5％-74％)all performed well.Conclusion The QR code-based APP prediction tool is of great significance for scientific research transformation and precise HAI control.
