ObjectiveTo investigate the mechanism of action of modified Chaihu Shugan Powder in the treatment of abnormal gallbladder relaxation in gallbladder cholesterol stone （CS） with liver depression syndrome， and to provide a basis for clinical medication. MethodsMice were given a high-fat lithogenic diet combined with chronic unpredictable mild stress （CUMS） to establish a model of CS. A total of 45 male C57BL/6 mice were randomly divided into blank group （6 mice fed a normal diet） and CS group （39 mice fed a high-fat lithogenic diet）. After CS modeling， the CS group was further randomly divided into four subgroups of CS group， CS liver depression group， traditional Chinese medicine group （treated with modified Chaihu Shugan Powder）， and Western medicine group （treated with ursodeoxycholic acid）， with 9 mice in each group. All subgroups were fed with the high-fat lithogenic diet， and all mice except those in the CS group were given 21 days of CUMS for modeling. Samples were collected after intervention. The serum levels of cholecystokinin （CCK）， liver function parameters， and blood lipid profiles were measured； HE staining was performed for liver and gallbladder tissue； qPCR and Western blot were used to measure the mRNA and protein expression levels of G protein-coupled bile acid receptor 1 （TGR5） and glucagon-likepeptide-1/2 （GLP-1/2） in the intestine and TGR5 and glucagon-like peptide-2 receptor （GLP-2R） in gallbladder； metabolomics methods were used to determine bile acid composition in intestinal contents. The independent-samples t-test was used for comparison of continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test or the Games-Howell method was used for further comparison between two groups. ResultsCompared with the blank group， the CS group showed significant gallstone formation， bile turbidity， hepatic steatosis， abnormal gallbladder wall structure， and significant increases in anxiety- and depression-like behaviors based on behavioral tests； significant increases in the level of total cholesterol in bile and the serum levels of alanine aminotransferase， aspartate aminotransferase， and low-density lipoprotein and significant reductions in the level of total bile acid （TBA） in bile and the serum levels of CCK and high-density lipoprotein （HDL） （all P<0.05）； significant increases in the mRNA expression levels of GLP-1/2 and TGR5 in the intestine and the protein expression levels of GLP-2R and TGR5 in the gallbladder and significant reductions in the mRNA expression levels of GLP-2R and TGR5 in the gallbladder （all P<0.05）； significant changes in multiple bile acid components in intestinal contents （all P<0.05）. Compared with the CS group， the CS liver depression group had further aggravation of pathological and behavioral manifestations， changes in bile acid composition， significant increases in the protein and mRNA expression levels of TGR5 and GLP-1/2 in the intestine， and significant increases in the protein and mRNA expression levels of TGR5 and GLP-2R in the gallbladder （all P<0.01）. Compared with the CS liver depression group， both treatment groups had an improvement in gallbladder morphology， alleviation of stones and liver injury， and recovery of liver function and blood lipid levels， as well as significant reductions in the protein and mRNA expression levels of TGR5 and GLP-1/2 in the intestine and TGR5 and GLP-2R in the gallbladder （all P<0.05）； the traditional Chinese medicine group showed significant increases in glycodeoxycholic acid （GDCA）， tauro-α-muricholic acid （T-α-MCA）， and taurochenodeoxycholic acid （TCDCA） （all P<0.05）， while the Western medicine group showed significant increases in taurohyodeoxycholic acid， T-α-MCA， TCDCA， GDCA， and glycoursodeoxycholic acid （all P<0.05）. Compared with the Western medicine group， the traditional Chinese medicine group had significantly greater behavioral improvements， significantly higher levels of TBA in bile and serum HDL （both P<0.01）， significant reductions in the protein expression levels of TGR5 and GLP-1/2 in the intestine and TGR5 and GLP-2R in the gallbladder， and a significant reduction in the mRNA expression level of TGR5 in the intestine （all P<0.01）， as well as a significant increase in tauroursodeoxycholic acid and significant reductions in glycoursodeoxycholic acid， taurohyodeoxycholic acid， TCDCA， and taurolithocholic acid （all P<0.05）. ConclusionModified Chaihu Shugan Powder can improve liver function and abnormal gallbladder relaxation in CS with liver depression syndrome by regulating the bile acid-TGR5 axis， thereby exerting the therapeutic effect of soothing the liver， resolving depression， moving Qi， and promoting bile flow.

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.

Objective To exploring the effect of inflammatory indicators on the outcome of assisted conception of in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)in patients with ovarian endometriosis(OEM).Methods The study subjects were selected as the patients with OEM who received IVF/ICSI treatment at the Third Affiliated Hospital of Zhengzhou University from January 2019 to February 2024.Based on whether previous surgery for uterine endometriosis cyst removal had been performed,they were divided into non-surgery group(n=73)and surgery group(n=112).To explore the differences in inflammatory markers between two groups and to determine whether they have an impact on the outcome of assisted reproduction.Results The lymphocytes(L)and blastocyst formation rates of patients in surgery group were significantly higher than those in non-surgery group,platelet to lymphocyte ratio(PLR)and carbohydrate antigen 125(CA125)were significantly lower than those in non-surgery group(P＜0.05).There were no statistically significant differences in the clinical pregnancy rate and live birth rate between two groups of patients(P＞0.05).After adjusting for confounding factors,the results of multivariate Logistic regression analysis showed that L,PLR,and CA125 had no statistically significant impact on the clinical pregnancy rate and live birth rate(P＞0.05).Both maternal age and the number of embryos transferred exerted a certain influence on clinical pregnancy rates and live birth rates(P＜0.05),furthermore,the type of embryo transferred had a significant effect on clinical pregnancy rates(P＜0.05).Conclusion Compared with non-surgery group,surgery group had higher L level and lower PRL and CA125 levels,but these changes did not significantly affect clinical pregnancy or live birth outcomes in OEM patients undergoing IVF/ICSI assisted reproduction.

Objective To understand the pathogenic molecular characteristics of the latest prevalent Group A Streptococcus(GAS)in a suburban area of Beijing.Methods Throat swab specimens from children suspected of GAS infection in the outpatient setting of a sentinel surveillance hospital in a suburban area of Beijing from January 2023 to June 2025 were collected.GAS strains were detected and cultured.Antimicrobial susceptibility testing on 12 antimicrobial agents were performed,and molecular epidemiological characteristics of GAS strains was further ana-lyzed by whole genome sequencing technique.Results Data of 326 children suspected of GAS infection in outpatient setting were collected.A total of 41 GAS strains were detected and cultured,with a detection rate of 12.58％.The proportions of children with anterior cervical lymph node enlargement,tonsil congestion,and jaw congestion in the GAS positive group were all higher than those in the GAS negative group,and differences were all statistically sig-nificant(all P＜0.05).All 41 GAS strains carried both erm(B)and tet(M)resistance genes and exhibited a struc-tural type(cMLS)resistance phenotype.All of the emm12 strains were ST36,and emm1 strains were ST28.A to-tal of 6 emm12 subtypes and 1 emm1 subtype were detected,namely emm12.2,emm12.95,emm12.69,emm12.17,emm12.19,emm12.149,and emm1.12.Among them,emm12.149 was a newly discovered subtype.Nucleobase at the 175 100 locus in gene sequence had undergone an A→ T mutation.A total of 5 bacteriophages and 6 superanti-gens were detected.There were statistically significant differences in multi-nucleotide polymorphisms(MNPs)and insertion numbers in the genomes of emm12.0 and emm12 subtypes(both P＜0.05).The phylogenetic tree presen-ted a highly clonal group of 23 GAS strains in this area,accounting for 57.50％.Conclusion The prevalent GAS strain in this area is emm12.emm12.149 is a new subtype.The resistance genes and phenotypes are erm(B),tet(M),and structural type(cMLS).The genome has plenty genetic polymorphism,and the genome sequences of multiple GAS strains are highly cloned,indicating the possibility of clone transmission.This suggests that the sur-veillance of GAS in sentinel hospitals should continue to be strengthened,so as to provide theoretical basis for the prevention and control of GAS epidemics.

Objective:To investigate the influencing factors and perinatal outcomes associated with monozygotic twins (MZT) following elective single embryo transfer (eSET) via in vitro fertilization or intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). Methods:A retrospective cohort study was conducted on 12 079 patients who achieved pregnancy after undergoing IVF/ICSI-eSET at Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University between January 2015 and September 2023. Patients were stratified into two groups based on ultrasound findings 30 d post-transfer: singleton pregnancy group and MZT pregnancy group. Finally, 300 MZT and 1 500 single pregnancies, which were randomly matched according to 1∶5 were included by study period. General patients' characteristics, embryo-related factors, and perinatal outcomes were compared between the two groups. A multivariate logistic regression model was employed to identify risk factors for MZT after single embryo transfer, adjusting for potential confounding variables.Results:The incidence of twin pregnancy following single embryo transfer was 2.48% (300/12 079), which was higher than that of naturally conceived monozygotic twin pregnancy. No significant difference was found in baseline characteristics between the two groups (all P>0.05). The blastocyst transfer rate was higher in the MZT pregnancy group [93.3% (280/300)] than in the singleton pregnancy group [88.8% (1 332/1 500), P=0.022]. Multivariate logistic regression analysis also showed that blastocyst transfer was associated with an increased risk of MZT ( OR=0.552, P=0.016, 95% CI: 0.341-0.894). Analysis of blastocyst cycles showed that the risk of MZT was higher when transferring high-quality blastocysts [79.6% (223/280) vs. 67.8% (903/1 332), P<0.001], where as a trophectoderm (TE) grading of C [20.4% (57/280) vs. 32.2% (429/1 332), P<0.001] had a lower risk of MZT. After adjusting for confounding factors, the risk of MZT was found to increase with the transfer of blastocysts with a B-grade inner cell mass (ICM) ( OR=0.601, P=0.001, 95% CI: 0.442-0.819) and A/B grade TE (grade A: OR=2.951, P<0.001, 95% CI: 1.980-4.399; grade B: OR=1.840, P<0.001, 95% CI: 1.315-2.576). The risk of complications during pregnancy [47.7% (143/300) vs. 19.3% (289/1 500), P<0.001], preterm labor [55.1% (140/254) vs. 7.4% (101/1 368), P<0.001], and the risk of stillbirth [3.7% (11/300) vs. 1.5% (22/1 500), P=0.016] were significantly higher in the MZT pregnancy group than in the singleton pregnancy group. Conclusion:Assisted reproductive technology may contribute to the risk of MZT. Transfer of blastocysts, particularly those with loose ICM arrangement and dense TE arrangement, appears to increase the risk of MZT in patients undergoing eSET.

Objective:To investigate the impact of different luteal phase support protocols on pregnancy outcomes in patients aged ≤35 years undergoing modified natural cycle frozen-thawed embryo transfer (mNC-FET).Methods:A retrospective cohort study was conducted to analyze 2 086 cycles of patients aged ≤35 years who received mNC-FET cycles in Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2020. The cycles were divided into three groups based on luteal phase support protocols used. The patients received a combination of progesterone soft capsule and dydrogesterone in the group A (446 cycles), the patients received dydrogesterone in the group B (439 cycles), and the patients received a combination of progesterone vaginal sustained-release gel and dydrogesterone in the group C (1 201 cycles). The pregnancy and perinatal outcomes were compared between groups A and B, groups C and B after matching the baseline data in a ratio of 1∶1 using the propensity score matching (PSM). The effect of different luteal phase support on live birth rate was analyzed after adjusting for confounding factors affected by univariate and multivariate generalized estimating equation (GEE).Results:After PSM, there were no significant differences between groups A and B, groups C and B in human chorionic gonadotropin positive rate, clinical pregnancy rate, ectopic pregnancy rate, live birth rate in transplant cycle, incidence of low weight, macrosomia, premature delivery rate, pregnancy complication rate and incidence of birth defects (all P>0.05). GEE analysis showed that three different luteal phase support regimens were not associated with live birth rate. Conclusion:In the mNC-FET cycle, patients aged ≤35 years who chose dydrogesterone alone as luteal phase support drug, had no difference in live birth rate and perinatal outcome between progesterone soft capsules or progesterone vaginal sustained-release gel combined with dydrogesterone, but the outcome still needs to be confirmed by large sample prospective studies.

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.

Objective To compare the clinical outcomes of the clomiphene citrate(CC)dual stimulation protocol and the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved in POSEIDON patients with low expected prognosis.Methods The clinical data from patients who underwent in vitro fertilization(IVF)or intracytoplasmic sperm injection(ICSI)at the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from May 2016 to December 2023 were analyzed retrospectively.According to the POSEI-DON criteria,including POSEIDON group 3 and group 4,which were treated with the CC dual stimulation protocol(the CC group)and the luteal-phase ovarian stimulation protocol after the natural cycle oocytes retrieval(the natural cycle group).The basic data and clinical outcomes of the two ovulation protocols were analyzed,and the main observations included the number of oocytes retrieved,the cumulative clinical pregnancy rate and the cumulative live birth rate,and explored the impact of ovulation promotion regimens on clinical outcomes through binary logis-tic regression.Results On the whole,there was no significant difference in the total number of oocytes retrieved,cumulative clinical pregnancy rate and live birth rate between the CC group and the natural cycle group(all P>0.05),And in POSEIDON group 4,the numbers of oocytes retrieved in the follicular phase of the CC group were higher than those in the natural cycle group,whereas the number of oocytes retrieved in the luteal phase of natural cycle group were higher,and the difference was statistically significant(P<0.05).After logistic regression analysis,the ovulation stimulation protocols did not affect the cumulative clinical pregnancy rate and live birth rate of POSEI-DON 3 and 4 group(P>0.05).Conclusions For the POSEIDON patients with a low expected prognosis,the clinical effectiveness of the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved is not inferior to that of the CC dual stimulation protocol.In POSEIDON group 4,on the premise that the AMH levels of patients in the natural cycle group were lower than those in the CC group,who underwent natural cycle ovulation followed by luteal phase induction achieved similar clinical outcomes to those of the CC dual stimulation protocol group.Therefore,the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved should be more clinically recommended for POSEIDON group 4 patients.

OBJECTIVE: To observe the effects of electroacupuncture (EA) with different frequencies on spermatogenic function, testicular morphology and oxidative stress in oligoasthenospermia (OAT) rats, and to explore the mechanism and the optimal parameters of EA for OAT. METHODS: Sixty SPF-grade male SD rats were randomly divided into a solvent control group, a model group, a 2 Hz EA group, a 100 Hz EA group and a 2 Hz/100 Hz EA group, with 12 rats in each group. Except for the solvent control group, the other 4 groups were administered ornidazole suspension (800 mg·kg^-1·d^-1) by gavage for 28 d to establish the OAT model. Starting from the 1st of modeling, EA was applied at "Guanyuan" (CV4), "Qihai" (CV6) and bilateral "Sanyinjiao" (SP6) and "Zusanli" (ST36) in the 3 EA groups, continuous wave of 2 Hz, continuous wave of 100 Hz, and disperse-dense wave of 2 Hz/100 Hz were used in the 2 Hz EA group, the 100 Hz EA group, and the 2 Hz/100 Hz EA group, respectively, with current intensity of 1-3 mA, 30 min a time, once every other day, for 28 consecutive days. After intervention, the testicular index was calculated, epididymal sperm quality was assessed, and the fertility ability was observed; morphology of testicular tissue was observed by HE staining, and the Johnson score was calculated; the positive expression of reactive oxygen species (ROS) in testicular tissue was detected by immunofluorescence; the activity of superoxide dismutase (SOD) and catalase (CAT), as well as the level of malondialdehyde (MDA) in testicular tissue were measured by ELISA; the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in testicular tissue was detected by Western blot. RESULTS: Compared with the solvent control group, in the model group, the testicular index, sperm concentration, sperm motility and the number of offspring were decreased (P<0.01), the seminiferous tubules atrophied and the Johnson score decreased (P<0.01); the activity of SOD and CAT, as well as the protein expression of Nrf2 and HO-1 in testicular tissue were decreased (P<0.01); the sperm deformity rate, the positive expression of ROS and the MDA level in testicular tissue were increased (P<0.01). Compared with the model group, in the 2 Hz EA group, the 100 Hz EA group and the 2 Hz/100 Hz EA group, the testicular index, sperm concentration, sperm motility and the number of offspring were increased (P<0.05, P<0.01), the pathological morphology of testicular tissue improved and the Johnson scores increased (P<0.01); the activity of SOD and CAT, as well as the protein expression of Nrf2 and HO-1 in testicular tissue were increased (P<0.05, P<0.01); the sperm deformity rate, the positive expression of ROS and the MDA level in testicular tissue were decreased (P<0.05, P<0.01). Compared with the 2 Hz EA group, in the 2 Hz/100 Hz EA group, the testicular index, sperm concentration, sperm motility, as well as the CAT activity and HO-1 protein expression in testicular tissue were increased (P<0.01, P<0.05); the positive expression of ROS was decreased (P<0.01). Compared with the 100 Hz EA group, in the 2 Hz/100 Hz EA group, the testicular index was increased (P<0.01), the positive expression of ROS in testicular tissue was decreased (P<0.01). CONCLUSION EA with 2 Hz continuous wave, 100 Hz continuous wave, and 2 Hz/100 Hz disperse-dense wave can all improve the spermatogenic arrest and reduce the level of oxidative stress in testicular tissue in OAT rats, the mechanism may be related to up-regulating the protein expression of Nrf2 and HO-1 and improving oxidative stress. EA with disperse-dense wave of 2 Hz/100 Hz shows the optimal effect.

The paper introduces 5 books written by WANG Mengying, including Suixiju Chongding Huoluan Lun, Guiyan Lu, Wenre Jingwei, Wang Mengying Yi'an and Suixiju Yinshipu; and analyzes the ideas of diagnosis and treatment of cholera and the academic thoughts in treatment with acupuncture-moxibustion therapy. In pathogenesis, cholera is classified into cold and heat types. Cholera of heat type roots on qi and blood. If the pathogenic factors are mild and located shallowly, the sneezing method, followed by scraping method, is adopted to open meridians and collaterals, as well as the qi level, so as to eliminate pathogens. When the pathogens go deeply, the bloodletting technique is used to clean the toxic heat in blood level and reduce the reversed qi. For cholera of cold type, warm ironing moxibustion is delivered to promote qi circulation and disperse cold, and improve qi movement. If spasm and syncope occur in cholera, no matter of cold or heat identification, the emergent measure is operated with the external application of pungent, warm and salty herbal plaster at Yongquan (KI1). When the pathogens are almost eliminated, the herbal medicines are combined to treat the symptoms and remove the causative factors of the disease.
