The oocyte， as the origin of life， provides half the chromosomes to the embryo and supplies the proteins， substrates， energy， and other support necessary for embryonic development. It is the decisive factor determining the embryo's developmental potential. Infertility caused by reproductive endocrine diseases targets the oocyte as the final target cell. Improving oocyte quality represents a key and difficult point in the field of modern reproductive medicine. The decline of oocyte quality is related to meiosis abnormalities， DNA damage， mitochondrial dysfunction， oxidative stress， and other mechanisms. For oocyte quality problems， there is no unified international guideline to recommend drugs. Because the drug intervention research on oocytes involves strict clinical ethical restrictions， the current relevant research only stays in the animal and in vitro experimental stage and has not yet been applied to the clinic. Traditional Chinese medicine compound formula has a multi-target and multi-pathway regulation mechanism and is widely used in clinics. More and more research began to pay attention to the potential mechanism of traditional Chinese medicine compound formulas in improving oocyte quality. Traditional Chinese medicine compound formula has the advantages of multi-target and multi-channel synergy as well as better safety， individualization， and conformity to clinical ethics in improving oocyte quality. This article systematically reviewed the research progress on traditional Chinese medicine compound formula interventions for oocyte quality， aiming to summarize existing findings and provide recommendations to improve oocyte quality and optimize the clinical diagnosis and treatment of female infertility within traditional Chinese medicine.

Objective To prepare in-house coagulation factor Ⅷ(F Ⅷ)inhibitor-positive control material and evaluate its perform-ance.Methods Frozen plasma samples from hemophilia A patients with positive factor Ⅷ inhibitors were pooled,and diluted with Owren's Veronal Buffer(OVB)to 1 BU/mL of the inhibitor concentration in the mixture,then aliquoted and freeze-stored.The homo-geneity and stability of the in-house quality control material were verified,and its suitability was further assessed through intra-laborato-ry reproducibility among different technologists and inter-laboratory comparisons.Results Twenty-one aliquots were randomly tested for homogeneity assessment,yielding an average of 1.05 BU/mL(range 0.9-1.15 BU/mL),with a standard deviation(SD)of 0.083 and coefficient of variation(CV)of 7.90％.The freshly prepared inhibitor-positive control samples contained a concentration of 1.03 BU/mL.After storage at-80℃ for 24 hours,1 week,1 month,2 months,3 months,4 months,5 months,6 months,7 months,8 months,and 9 months,thawed the samples showed relative deviations of 9％,0％,10％,9％,14％,15％,6％,0％,-10％,-5％,and 2％,respectively.The intra-laboratory CV value from different technologists at this center was 7.28％,and the inter-labora-tory CV across different centers was 18.75％.Conclusion The prepared in-house positive control material of Factor Ⅷ inhibitor ex-hibited adequate uniformity and stability.

AIM To investigate the mechanism of Jiedu Yizhi Formula on cognitive function and neuroinflammation in a mouse model of Alzheimer's disease(AD).METHODS 50 APP/PS1 double transgenic mice were randomly divided into the model group,the donepezil group,and the low-dose,moderate-dose,and high-dose Jiedu Yizhi Formula group(1.78,3.56 and 7.12 g/kg),with 10 mice in each group,in contrast to the 10 WT mice of the blank group.Following anesthesia administration and 8-week oral gavage regimen with respective drugs,all mice underwent final tissue sample collection.The mice had their learning and memory ability assessed by Morris water maze and nesting behavior scores;their pathology of brain tissue and Aβ expression observed using HE,Nissl and IHC staining;their polarization of microglia and the expression of inflammatory factors in hippocampal tissue detected by IF and ELISA;their hippocampal expression of PI3K/Akt/mTOR signaling pathway detected by RT-qPCR and Western blot.RESULTS Compared with the blank group,the model group had lower scores in total swimming distance,frequency in crossing the platform,residence time in the target quadrant,and nesting behavior scores(P＜0.05,P＜0.01);prolonged evasion latency(P＜0.01);more disorganized arrangement of pyramidal cells,solidification and deep staining,unclear demarcation,irregular cell shapes,reduction of Nyctinidia,and increased Aβ deposition in the brain tissue(P＜0.01);elevated expression of hippocampal microglia M1-type markers CD16/32 and lba-1(P＜0.01);decreased levels of M2-type marker CD206(P＜0.05);elevated levels of TNF-α and IL-1β(P＜0.01);decreased expressions of IL-13 and IL-4(P＜0.01);and decreased levels of PI3K,Akt and mTOR mRNA,and reduced p-PI3K,p-Akt and p-mTOR protein expressions(P＜0.01).Compared to the model group,the donepezil group and the Jiedu Yizhi Formula groups showed statistically significant improvements in the aforementioned indexes(P＜0.05,P＜0.01),with the magnitude of improvement being higher in the high-dose Jiedu Yizhi Formula group.CONCLUSION Jiedu Yizhi Formula suppresses microglia Ml-type polarization while enhancing M2-type polarization via activation the PI3K/Akt/mTOR signaling pathway,which subsequently reduces inflammatory cytokine secretion.This mechanism attenuates Aβ deposition in brain tissues and ameliorates cognitive dysfunction in AD mouse models.

Objective:To investigate the clinical features and multi-slice spiral computed tomography(CT)imaging features of acute appendicitis in soldiers who have been living in plateau for a long time.Methods:The clinical features and imaging data of 56 cases of acute appendicitis in soldiers who have been living in plateau for a long time confirmed by surgery from February 2022 to August 2024 were retrospectively analyzed.Results:In 56 cases with acute appendicitis in soldiers who have been living in plateau for a long time,the appendectomy position results showed:anterior ileum 4 cases(7.14％),lower ileum 10 cases(17.86％),posterior cecum 16 cases(28.57％),lower cecum 9 cases(16.07％),lateral cecum 2 cases(3.58％),posterior ileum 6 cases(10.71％),high(subhepatic)9 cases(16.07％),and left lower abdominal 0 cases,retroperitoneal appendicitis 0 cases,which was suggested that the anatomical position variation of appendicitis in soldiers with acute appendicitis who have been living at high altitude for a long time was relatively large.The direct manifestations of multi-slice spiral CT showed:appendectomy enlarged diameter＞6 mm in 49 cases(87.50％),appendicular wall thickening＞2 mm in 42 cases(75.00％),ppendiceal dilation lumen and effusion in 29 cases(51.79％),appendix indistinctness in 3 cases(5.36％),lppendix fecalith:27 cases(48.21％),gas in the appendix in 16 cases(28.57％).Indirect findings of multi-slice spiral CT showed that,periappendiceal exudation with shadow in 32 cases(57.14％),appendiceal cellulitis with peripheral abscess in 9 cases(16.07％),peritonitis and ascites in 13 cases(23.21％),ileocecal intestinal wall thickening in 22 cases(39.29％),mesenteric lymph node enlargement in 16 cases(28.57％),reflexive intestinal stasis in ileocecal region was observed in 19 cases(33.93％).Conclusion:In the officers and soldiers with acute appendicitis who lived at high altitude for a long time,multi-slice spiral CT showed the direct manifestations of appendiceal thickening,tube wall thickening,lumen dilatation,fluid accumulation,etc.,and the indirect manifestations were periappendiceal exudation with shadow,appendiceal cellulitis with peripheral abscess,ileocecal intestinal wall thickening,reflexes of small intestine and mesenteric lymph node enlargement.Multi-slice spiral CT has the advantages of clear and intuitive,high safety,high resolution and simple operation in the diagnosis of acute appendicitis.

Aim To investigate the therapeutic effect of newly formulated Tadalafil tablets on liver fibrosis in mice induced by carbon tetrachloride(CCl4)and its impact on the activation of hepatic stellate cells(HSCs).Methods Liver fibrosis model was estab-lished by intraperitoneally injecting 20％CCl4 corn oil solution twice a week for eight weeks.After four weeks of modeling,the treatment group was administered ei-ther the newly formulated Tadalafil tablets(1.0 mg·kg-1)or the Cialis(2.5 mg·kg-1)via gavage for the remaining four weeks.We assessed the effects of Tadalafil on collagen deposition,tissue structural dam-age,and HSCs activation markers in the fibrotic liver of mice using serum biochemical analysis,histopathologi-cal staining,and Western blotting following the treat-ment period.LX-2 cells were cultured and treated with tadalafil after TGF β1 stimulation,and the effects of tadalafil on LX-2 cell activation were assessed via Western blot.Results Compared to the normal mice,the model group mice exhibited a significantly higher liver-specific index,increased liver function indicators,and notable hepatocyte necrosis.Additionally,liver lobules were damaged,accompanied by severe infiltra-tion of inflammatory cells.Both smooth muscle actin(α-SMA)and fibronectin(Fn)were elevated,serving as markers of HSCs activation.As a result of treatment with the newly formulated Tadalafil tablets,liver tissue damage was significantly reduced,transaminase levels decreased,necrosis and inflammatory cell infiltration were reduced,and collagen fiber deposition was allevia-ted,and α-SMA and Fn expression was reduced.It was worth noting that low-dose newly formulated Tadalafil tablets were found to be as effective as high-dose Cia-lis.In a cellular model,Tadalafil significantly inhibited the activation of LX-2 cells and reduced the expression of proteins related to cell activation.Conclusions The newly formulated Tadalafil tablets can significantly inhibit HSCs activation,reduce extracellular matrix(ECM)deposition,improve liver fibrosis and liver function damage caused by CCl4.This new formulation offers a significant advantage over Cialis in terms of ef-fectiveness,with a lower effective dose.

Objective:To study the outcomes of the modified Devine + Shiraki surgical approach in the treatment of severe concealed penis.Methods:A retrospective analysis was conducted on the clinical data of initially treated patients with severe concealed penis admitted to the Department of Urology, Henan Provincial People’s Hospital from March 2020 to September 2022. The therapeutic effects of three surgical approaches (Devine, Shiraki, and modified Devine + Shiraki) were analyzed and compared. The Devine approach mainly focuses on eliminating the pathological morphology of the concealed penis, thoroughly releasing the penile shaft, and correcting the concealed state; the Shiraki approach emphasizes the rational distribution of skin flaps; the key of the modified Devine + Shiraki approach lies in combining the advantages of the two approaches, achieving both complete correction of the concealed state and rational distribution of skin flaps. Improvements were made to the conventional surgical sequence: skin flap distribution was pre-designed before correcting the concealed penis to avoid difficulties in skin flap arrangement caused by degloving, thereby preventing postoperative complications such as stricture rings, lymphedema, or erectile pain. Three months after the operation, follow-up was performed to assess incision healing, presence of lymphedema or stricture rings, satisfaction with penile exposure, recurrence of the concealed state, urination patency, presence of urethral injury, and normal erectile function. A patient satisfaction survey was conducted 6 months after the operation. Measurement data with normal distribution were expressed as Mean± SD, and one-way analysis of variance was used for comparison among the three groups; categorical variables were expressed as case numbers and percentages, and chi-square test was used for comparison among the three groups. Results:Eighty, fifty, and forty-five male children were enrolled in the Devine + Shiraki group, Devine group, and Shiraki group, respectively. There were no statistically significant differences in age and body mass index (BMI) among the three groups [age: (7.6±4.5) years vs. (7.2±4.4) years vs. (6.7±4.2) years, F=0.61, P=0.546; BMI: (17.4±3.1) kg/m 2 vs. (17.7±3.2) kg/m 2 vs. (18.0±3.3) kg/m 2,F=0.57, P=0.565]. During surgery, all concealed penile shafts were completely released, and the penile skin was rationally distributed. The postoperative follow-up period ranged from 3 months to 18 months, with an average follow-up time of 13.6 months. At the 3-month postoperative follow-up, all three groups showed satisfactory wound healing with no signs of infection or skin flap necrosis; penile skin coverage was adequate, and all children demonstrated unobstructed urination without evidence of urethral injury; normal erectile function was preserved in all cases, with no reports of erectile dysfunction or pain. The recurrence rate of the concealed penis in the Devine + Shiraki group was significantly lower than that in the Devine group and Shiraki group, with a statistically significant difference [0 (0/80) vs. 6.0% (3/50) vs. 31.1% (14/45), χ2=32.88, P<0.001]; the proportion of patients without postoperative lymphedema and stricture rings in the Devine + Shiraki group was higher than that in the Devine group and Shiraki group, with a statistically significant difference [97.5% (78/80) vs. 70.0% (35/50) vs. 86.7% (39/45), χ2=20.39, P<0.001]. The Devine+ Shiraki, Devine, and Shiraki groups reported postoperative satisfaction in 76 (95.0%), 35 (70.0%), and 31 (68.9%) cases, respectively. Conclusion:The modified Devine + Shiraki surgical approach has definite efficacy, good safety, and a low incidence of complications, and can be used as an option for the treatment of severe concealed penis.

Objective:To investigate the efficacy and safety of sintilimab combined with the SOX regimen for adjuvant treatment of stage Ⅲgastric cancer after D2 radical resection and to provide a reference for individualized clinical treatment.Methods:The clinical data of 245 pa-tients with stage III gastric cancer who underwent D2 radical resection at the 940th Hospital of the Joint Support Force of the People's Liber-ation Army from June 2019 to May 2022 were retrospectively analyzed.The 180 patients who received only the SOX regimen were desig-nated the control group,and the 65 patients who received sintilimab combined with the SOX regimen were designated the experimental group.The 3-year disease-free survival(DFS)rate,overall survival(OS)rate,and adverse reactions among the two groups and different sub-groups(HER-2 positive,dMMR,CPS≥5)were compared.Results:The 3-year DFS(81.5%vs.59.4%)and OS(84.6%vs.70.6%)rates in the experimental group were significantly higher than those in the control group(both P<0.05).Group analysis showed that in patients with CPS≥5,the 3-year DFS(91.5%vs.67.0%)and OS(95.7%vs.71.6%)rates within the experimental group were significantly better than those in the control group(both P<0.05).Intra-group analysis within the experimental group showed that the 3-year DFS rate(91.5%vs.55.6%)and OS rate(95.7%vs.55.6%)of patients with CPS≥5 were significantly better than those of patients with CPS<5(both P<0.05).The overall and grade≥3 incidences of liver and kidney function damage,thyroid dysfunction,colitis,pneumonia,and rash in the experimental group were higher than those in the control group(all P<0.05),while the differences in other adverse reactions,including leukopenia were not statistic-ally significant(all P>0.05).Conclusions:Sintilimab combined with the SOX regimen can significantly improve 3-year DFS and OS rates in pa-tients with stage Ⅲ gastric cancer after surgery,especially in the CPS≥5 subgroup,with significant benefits and controllable safety.

Objective To understand the current status of the job competency of full-time healthcare-associated in-fection(HAI)management professionals in all levels and types of medical institutions across China,and provide in-formation and basis for professional training,competency improvement,and career planning.Methods The strati-fied sampling method was adopted to select HAI management professionals from medical institutions in 31 provin-cial-level administrative regions across the country as the research subjects.The designed content of questionnaire involved four parts,including the surveyed personnel's basic information,daily job competency assessment,satis-faction level towards the job,as well as opinions and suggestions on the management of full-time HAI management professionals.The assessment on daily job competency was divided into 13 dimensions,ranging from very incompe-tent to very competent in 5 levels.The scores of HAI management professionals with different professional back-grounds were compared and analyzed.Results A total of 8 709 valid questionnaires were collected,with 3 475 and 3 697 surveyed personnel from tertiary and secondary medical institutions,respectively,and 1 537 from primary or unclassified medical institutions.The overall average score for the competency assessment of full-time HAI manage-ment professionals was(4.17±0.80)points.The scores of professionals with different professional backgrounds,from high to low,were as follows:nursing([4.12±0.81]points),clinical medicine([4.07±0.86]points),pre-ventive medicine([3.93±0.92]points),laboratory medicine([3.88±0.93]points),pharmacy([3.86±0.94]points),and health management([3.85±0.95]points).For the core competency of HAI management professio-nals,such as monitoring and analyzing HAI cases,identifying and investigating HAI outbreaks,the assessment scores for professionals with medical backgrounds were the highest(both P＜0.05).For the basic work of HAI prevention and control,such as checking and guiding the implementation of rules and regulations,guiding occupa-tional protection,management and communication,and implementing HAI management training,professionals with a nursing background had the highest assessment scores(all P＜0.05).Full-time HAI management professionals were relatively satisfied with their training,while those with a background in preventive medicine had lower satisfac-tion with their training,career development,and job benefits(all P＜0.05).Conclusion There are significant differences in the competency of HAI management professionals with different professional backgrounds.It is nece-ssary to optimize division of labor and leverage the strengths,providing ideas and models for promoting the construction of a specialized and professional HAI management team.
