ObjectiveTo explore the evolution of medication patterns and syndrome-herb associations of traditional Chinese medicine （TCM） in treating inflammatory bowel disease （IBD）， providing a theoretical foundation for precise syndrome differentiation and treatment in clinical practice. MethodsMedical case literature on TCM treatment of IBD from 1960 to 2024 was retrieved to establish a database. Frequency statistics， cluster analysis， change point detection， and association rule mining were employed to comprehensively analyze the syndrome distribution， therapeutic methods， medication patterns， and their temporal variations. ResultsA total of 685 medical cases were included. Common syndromes were dampness-heat （66.42%） and spleen deficiency （56.20%）. Primary therapeutic methods included heat clearing （63.65%）， spleen invigorating （47.45%）， and dampness draining （36.79%）. High-frequency herbs included Coptidis Rhizoma （354）， Paeoniae Radix Alba （303）， Aucklandiae Radix （292）， Codonopsis Radix （253）， and Glycyrrhizae Radix et Rhizoma （244）. Initial prescription clustering revealed three core therapeutic method combinations： heat clearing and detoxifying （represented by Baitouweng Tang）， spleen invigorating and Qi reinforcing （represented by Shenling Baizhusan）， and cold-heat regulation （represented by Wumeiwan combined with Shaoyao tang）. Temporal analysis identified 2008 as a key transition point in TCM treatment of IBD， with significantly increased usage frequency of heat-clearing and dampness-drying herbs such as Fraxini Cortex， Phellodendri Chinensis Cortex， Sophorae Flavescentis Radix， and Scutellariae Radix as well as hemostatic herbs such as carbonized Sanguisorbae Radix， Bletillae Rhizoma， Agrimoniae Herba， and Notoginseng Radix et Rhizoma. Follow-up efficacy analysis showed median improvement rates of 64.0% at the first follow-up， 76.0% at the second follow-up， and 78.7% at the third follow-up. Syndrome-drug association analysis revealed specific herb pairs with significant therapeutic advantages， including Notoginseng Radix et Rhizoma + Coicis Semen， Sanguisorbae Radix + Coptidis Rhizoma， and Codonopsis Radix + Aconii Lateralis Radix Praeparaia. ConclusionTCM medication patterns for treating IBD demonstrate distinct temporal evolution characteristics， with significantly increased usage frequency of herbs such as Fraxini Cortex， Notoginseng Radix et Rhizoma， and Agrimoniae Herba. Significant therapeutic method-herb associations and syndrome-herb association patterns exist， with the formation of specific herb pairs， providing evidence-based support for precise syndrome differentiation and treatment of IBD.

Objective:To investigate the status of allostatic load (AL) in patients with polycystic ovary syndrome (PCOS) and its influence on the clinical outcomes of in vitro fertilization-embryo transfer.Methods:This was a prospective study. By using convenient sampling method, 421 patients with PCOS (PCOS group) and 372 control infertility patients (control group) in the Reproductive Center of the First Affiliated Hospital of Anhui Medical University from April 2022 to January 2024 were investigated for basic information, physical examination, laboratory examination and follow-up of clinical outcomes. The total score of AL was calculated using 16 related indicators of cardiovascular system, metabolic system and immune system, and AL>3 was used as the judgment criteria for the high level AL group and the low level AL group. The differences in general data, embryo development and clinical outcomes between the groups were compared.Results:There were 222 cases (52.7%, 222/421) in PCOS low level AL group and 199 cases (47.3%, 199/421) in PCOS high level AL group. There were 214 patients (57.5%, 214/372) in the control low level AL group and 158 patients (42.5%, 158/372) in the control high level AL group. Embryo development outcomes: number of oocytes retrieved (median: 12, 12, 19, 14, respectively; P<0.001), number of two pronuclei (median: 8, 7, 11, 8, respectively; P<0.001), number of fertilization (median: 9, 9, 13, 10, respectively; P<0.001), number of metaphase of meiosis Ⅱ oocytes (median: 9, 8, 13, 10, respectively; P<0.001), number of transferable embryos (median: 5, 5, 7, 6, respectively; P<0.001), number of high-quality embryos (median: 4, 3, 6, 5, respectively; P<0.001), gonadotropin(Gn) starting dosage (median: 150, 200, 150, 200 U, respectively; P<0.001), total dosage of Gn (median: 1 800, 2 075, 1 575, 2 025 U, respectively; P<0.001), duration of Gn used (median: 10, 10, 10, 10 days, respectively; P=0.027) in the control low level AL group, control high level AL group, PCOS low level AL group and PCOS high level AL group were significantly different. Pairings between groups showed that number of oocytes retrieved, number of two pronuclei, number of fertilization, number of metaphase of meiosis Ⅱ oocytes and number of transferable embryos in PCOS high level AL group were lower than those in PCOS low level AL group (all P<0.05); Gn starting dosage and total dosage of Gn in PCOS low level AL group were lower than those in the other three groups (all P<0.05); duration of Gn used in PCOS high level AL group was higher than that PCOS low level AL group ( P<0.05). Clinical outcomes: the control low level AL group, control high level AL group, PCOS low level AL group and PCOS high level AL group underwent fresh transplantation [27.4% (57/208), 24.4% (38/156), 15.1% (32/212), 17.1% (33/193), respectively; P=0.006] and the proportion of transplanted day 5 embryos [82.7% (172/208), 77.6% (121/156), 91.0% (193/212), 86.5% (167/193), respectively; P=0.018] were statistically significant. There were no significant differences in fertilization rate, biochemical pregnancy rate, clinical pregnancy rate, multiple pregnancy rate and early abortion rate among the four groups (all P>0.05). Conclusion:The high level of AL in PCOS patients may affect the outcomes of embryo development, and more attention should be paid to AL in PCOS patients to reduce stress.

Colorectal cancer is the third leading cause of cancer-related mortality worldwide.Hepatic resection is the standard treatment for colorectal cancer liver metastasis.Microwave ablation(MWA),as a minimally invasive therapeutic approach,offers an alternative treatment option for these patients.But the clinical efficacy of hepatic resection and MWA in treating colorectal cancer liver metastasis patients is still inconclusive.Literatures were retrieved on comparative studies about the treatment of colorectal cancer liver metastasis with hepatic resection and MWA from multiple databases,including sinoMed,PubMed,Web of Science,EMBASE,CNKI,Wanfang,etc.The cutoffdate of retrieval was September 2024.Finally,a total of 13 studies comprising 2 057 patients,were included in this study.The papers were assessed using the Newcastle-Ottawa Scale and Jadad Scale.All included studies were of high quality.Data extraction focused on postoperative complications,length of hospital stay,surgical duration,hospitalization costs,and patient survival outcomes,including overall survival(OS)and disease-free survival(DFS).A meta-analysis was performed using Review Manager 5.4 software.There were no significant differences in OS(HR=1.03,95%CI:0.85-1.25,P=0.77)and DFS(HR=1.27,95%CI:0.94-1.71,P=0.13)between the MWA group and the hepatic resection group.In the subgroup analysis of patients with≤5 liver metastases and size of metastases≤3 cm,there were no statistically significant differences in OS and DFS between the MWA group and the hepatic resection group.The MWA group exhibited shorter hospital stay,reduced hospitalization costs,decreased surgical duration,less intraoperative blood loss,and lower incidence of complications compared to the hepatic resection group(P＜0.05).Therefore,for patients with colorectal liver metastases characterized by a number of liver metastases≤5 and size of metastases≤3 cm,MWA serves as an effective alternative to hepatic resection,with a lower morbidity associated with treatment.Further validation of these findings is warranted through additional randomized controlled trials and cohort studies.The registration number of this Meta-analysis on the PROSPERO platform is CRD42024610278.

Objective:To establish a general method for the simultaneous determination of hydroxyphenyl esters and quaternary ammonium bacteriostatic agents in eye drops.Methods:The chromatographic analysis was per-formed on an Agilent C18 column(4.6 mm ×250 mm,5 μm)with 1％triethylamine solution(pH adjusted to 5.0 with phosphoric acid)as mobile phase A and methanol as mobile phase B.Gradient elution was performed at col-umn temperature of 40 ℃.The detection wavelength was 214 nm,the flow rate was 1 mL·min-1,and the injec-tion volume was 20 μL.Results:Methylparaben,ethylparaben,propylparaben,butylparaben,benzalkonium chlo-ride and benzalkonium bromide were 0.11-559.0,0.10-513.0,0.10-258.8,0.11-270.5,1.07-537.0 and 1.03-512.8 μg·mL-1,respectively.The linear range was good(r＞0.999).The average recoveries of meth-ylparaben,benzalkonium bromide and benzalkonium chloride were 104.7％(RSD=1.3％),102.6％(RSD=1.1％)and 100.9％(RSD=1.1％),respectively.The contents of bacteriostatic agent in 100 batches of eye drops from 36 varieties of 12 enterprises were determined,and the accurate results were obtained.Conclusion:This meth-od provides a reference for the content quality control and safety evaluation of bacteriostatic agents in eye drops.

Objective:To investigate the influence of polycystic ovary syndrome (PCOS) patients with different body mass index (BMI) on perinatal and neonatal outcomes of frozen-thawed embryo transfer.Methods:A retrospective cohort study was performed on the clinical data of patients with PCOS infertility who underwent cryopreservation transplantation in Reproductive Center of the First Affiliated Hospital of Anhui Medical University from 2016 to 2020. The clinical pregnancy was singleton, a total of 1 481 cycles were divided into 4 groups according to BMI value. There were 75 cycles in the underweight group (BMI<18.5 kg/m 2), 793 cycles in the normal weight group (18.5 kg/m 2≤BMI<24.0 kg/m 2), 468 cycles in the overweight group (24.0 kg/m 2≤BMI<28.0 kg/m 2), 145 cycles in the obese group (BMI≥28.0 kg/m 2). The differences of general information, perinatal outcome and neonatal outcome were compared among the four groups. Results:Compared with the overweight group, the normal weight group and the underweight group, the obesity group had the highest early abortion rate [23.4% (34/145) vs. 15.8% (74/468) vs. 14.0% (111/793) vs. 9.3% (7/75), P=0.014], and the lowest live birth rate [68.3% (99/145) vs. 76.7% (359/468) vs. 79.7% (632/793) vs. 88.0% (66/75), P=0.003]. The incidence of gestational diabetes in the obesity group and the overweight group [6.9% (10/145) and 4.5% (21/468)] was higher than that in the normal weight group [2.3% (18/793)] (the obesity group vs. the normal weight group P=0.005, the overweight group vs. the normal weight group P=0.028). The rate of cesarean section in the obesity group and the overweight group [81.8% (81/99), 74.9% (269/359)] was higher than that in the normal weight group [67.6% (427/632)] and the underweight group [57.6% (38/66), the obesity group vs. the normal weight group P=0.005, the obesity group vs. the underweight group P=0.001, the overweight group vs. the normal weight group P=0.015, the overweight group vs. the underweight group P=0.004]. The macrosomia birth rate [18.2% (18/99), 15.6% (56/359)] was also higher than that of the normal weight group [10.1% (64/632)] and the underweight group [6.1% (4/66), the obesity group vs. the normal weight group P=0.018, the obesity group vs. the underweight group P=0.025, the overweight group vs. the normal weight group P=0.011, the overweight group vs. the underweight group P=0.041]. There were no significant differences in late abortion rate, gestational hypertension, ectopic pregnancy and premature birth rate, Apgar score, height and birth defects (all P>0.05). Conclusion:Obesity and overweight affect the perinatal outcomes and neonatal outcomes in patients with PCOS. In clinical work, attention should be paid to the weight management of PCOS patients.

BACKGROUND: Hepatitis B is a viral infection that attacks the liver and can cause both potentially life-threatening acute and chronic liver disease. China has the world's largest burden of hepatitis B and is considered to be a major contributor toward the goal of World Health Organization (WHO) of eliminating hepatitis B virus (HBV) as a global health threat by 2030. This study aimed to analyze data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to determine the trends in mortality of liver disease due to hepatitis B in China between 1990 and 2019 and the gap with the WHO's goal. METHODS: Annual deaths and age-standardized mortality rates (ASMRs) of liver disease due to hepatitis B in China between 1990 and 2019 were collected from GBD 2019. We calculated the percentage changes in deaths and estimated annual percentage changes (EAPCs) of ASMRs of liver disease due to hepatitis B. RESULTS: In China, deaths of total liver disease due to hepatitis B decreased by 29.13% from 229 thousand in 2016 to 162 thousand in 2019, and ASMR decreased by an average of 4.92% (95% confidence interval [CI]: 4.45-5.39%) per year in this period. For the spectrum of liver disease due to hepatitis B, deaths decreased by 74.83%, 34.71%, and 23.34% for acute hepatitis, cirrhosis and other chronic liver diseases, and liver cancer from 1990 to 2019, respectively, and ASMRs of acute hepatitis (EAPC = -7.63; 95% CI: -8.25, -7.00), cirrhosis and other chronic liver diseases (EAPC = -4.15; 95% CI: -4.66, -3.65), and liver cancer (EAPC = -5.17; 95% CI: -6.00, -4.33) decreased between 1990 and 2019. The proportions of older adults aged ≥70 years among all deaths of the spectrum of liver disease due to hepatitis B increased from 1990 to 2019. Deaths of liver cancer due to hepatitis B increased by 7.05% from 2015 to 2019. CONCLUSIONS Although a favorable trend in the mortality of liver disease due to hepatitis B was observed between 1990 and 2019, China still faces challenges in achieving the WHO's goal of eliminating HBV as a public threat by 2030. Therefore, efforts to increase the coverage of diagnosis and treatment of liver disease due to hepatitis B, especially of liver cancer due to hepatitis B, are warranted in China.

Objective To revise the determination method in the quality standard of Jingtian Zhitong cream. Methods The total saponins of angelica sinensis, Ligusticum wallichii, Rhizoma corydalis, and Panax notoginseng saponins were qualitatively identified by thin-layer chromatography (TLC). The contents of notoginsenoside R₁, ginsenoside Rg₁, and ginsenoside Rb₁ in the preparation were determined by high performance liquid chromatography (HPLC). Results TLC showed strong specificity and good resolution. The concentration of notoginsenoside R₁ showed a good linear relationship in the range of 0.1604 and 2.0050μg (r=0. 999). The concentration of ginsenoside Rg₁ showed a good linear relationship in the range of 0.8003 and 10.0035μg (r=1.000). The concentration of ginsenoside Rb₁ showed good linearity in the range of 0.6182 and 7.7275μg (r=1.000). The sample recovery rates were 101.43%, 98.75% and 100.95%, respectively. The relative standard deviation (RSD) were 2.56%, 2.71% and 2.75%, respectively. Conclusion The developed method is accurate and reliable with high sensitivity, which can be used for the quality control of Jingtian Zhitong cream.
