The disease-syndrome combination animal model in traditional Chinese medicine （TCM） andrology serves as an important bridge linking TCM theory with modern medical research， providing a key experimental platform for elucidating the 'syndrome-disease' correlation mechanism in male-specific diseases and for screening effective prescriptions. This article reviews recent progress in animal model research on common TCM andrological diseases， including prostatic diseases， sexual dysfunction， and male infertility， with a focus on analyzing the application， advantages， and disadvantages of various modeling strategies， such as immune induction， hormonal intervention， and multi-factor combination across different syndrome types. However， despite breakthroughs in model construction techniques， current research still faces several challenges， including insufficient standardization of syndrome differentiation and difficulties in quantifying TCM-specific indicators. Future studies need to optimize model evaluation systems by integrating modern technologies， in order to promote the standardization and internationalization of TCM andrology research.

ObjectiveTo study the effect of Zuoguiwan on the development of skin barrier in the neonatal rat model of congenital kidney deficiency and unveil the underlying mechanism. MethodsSixty rats were paired in a female-to-male ratio of 2∶1， and the pregnant rats were assigned into control， congenital kidney deficiency， and low- and high-dose （2 and 8 g·kg^-1， respectively） Zuoguiwan groups. The pregnant rats in other groups except the control group were exposed to chronic unpredictable mild stress for the modeling of congenital kidney deficiency. The rats in the control group and congenital kidney deficiency group were administrated with normal saline by gavage， and those in Zuoguiwan groups with Zuoguiwan suspension by gavage from day 1 of pregnancy. The serum level of interleukin-6 （IL-6） in the neonatal rats on the day of birth was determined by enzyme-linked immunosorbent assay. The full-thickness skin of neonatal rats on the day of birth was removed from the same position on the back and stained with hematoxylin-eosin for observation of histopathological changes， measurement of skin thickness， and counting of hair follicles. Terminal deoxynucleotidyl transferase-mediated nick end labeling was used to detect the apoptosis of skin tissue cells. The expression of interleukin-6 receptor （IL-6R） and interleukin-17A （IL-17A） in the skin tissue was assessed by immunohistochemistry and Western blot， and the expression of occludin， connexin 43 （Cx43）， and zonula occludens-1 （ZO-1） in the skin tissue was assessed by immunofluorescence and Western blot. ResultsCompared with those in the control group， the neonatal rats in the congenital kidney deficiency group showed a rise in the serum IL-6 level （P<0.01）， decreases in stratum corneum thickness， skin thickness， and number of hair follicles （P<0.01）， increases in the expression of IL-6R and IL-17A in the skin tissue （P<0.01） and the number of apoptotic cells （P<0.01）， and decreases in the expression of occludin， Cx43， ZO-1 （P<0.05）. Compared with the congenital kidney deficiency group， the low- and high-dose Zuoguiwan groups showed declines in serum IL-6 level （P<0.05）. The low-dose group showed increased number of hair follicles （P<0.05）， and the high-dose group presented thickened stratum corneum （P<0.01）， increased number of hair follicles （P<0.01）， and down-regulated expression of IL-6R and IL-17A in the skin tissue （P<0.05， P<0.01）. Both Zuoguiwan groups showcased decreased number of apoptotic cells （P<0.05， P<0.01）， and the high-dose group showed up-regulated expression of occludin， Cx43， and ZO-1 in the skin tissue （P<0.05， P<0.01）. ConclusionZuoguiwan can reduce the levels of IL-6 in the serum and IL-6R and IL-17A in the skin tissue and improve the expression of intercellular junction proteins， thereby ameliorating the abnormal development of the skin barrier in the neonatal rat model of congenital kidney deficiency.

ObjectiveTo observe the clinical efficacy and safety of Shugan Bushen Yulin Decoction （疏肝补肾毓麟汤， SBYD） in the treatment of asthenospermia and infertility with liver constraint and kidney deficiency. MethodsA multicenter， randomized， controlled clinical study was conducted in three hospitals in central China. Totally 95 patients with asthenospermia and infertility were controlled. According to random number table， the patients were divided into treatment group （47 cases） and control group （48 cases）. The control group was given vitamin E soft capsules （100 mg per time， twice daily） orally， and the treatment group was given SBYD （one dose daily， 30 min after breakfast and dinner， about 200 ml each time） orally. The course of treatment was 12 weeks in both groups. After the treatment， the sperm concentration， percentage of forward motile sperm （PR）， and percentage of total sperm activity， that is PR + percentage of non-progressively motile sperm （NP） were compared between groups， and the clinical efficacy was judged. Traditional Chinese medicine （TCM） syndrome score （inlcuding 6 single symptom scores and total symptoms score） and 21-item depression， anxiety， and stress scale （DASS-21） scores （including depression， anxiety and stress scores） were compared between the two groups before and after treatment. The patients were followed up for 6 months， and the pregnancy status of spouse between groups was compared. The occurrence of adverse events and vital signs during the trial were recorded for safety assessment. ResultsTwo cases in the treatment group and three cases in the control group dropped out. Finally， 45 cases in each group were included in the statistical analysis. The total effective rate was 86.67% （39/45） in the treatment group， significantly higher than 73.74% （33/45） in the control group （P＜0.05）. After treatment， PR and PR + NP significantly increased in both groups， and were much higher in the treatment group than in the control group （P＜0.05）. The scores of lumbar and knee soreness， emotional disturbance， cold sperm， chest and rib-side and lesser abdomen distension and pain， frequent sighing， and the total TCM syndrome score in the treatment group decreased after treatment （P＜0.05）； and except for cold sperm， the scores of other symptoms mentioned above as well as the total TCM syndrome score in the treatment group were lower than those in the control group （P＜0.05）. The scores of depression， anxiety and stress of DASS-21 in the treatment group decreased after treatment， and were lower than those in the control group （P＜0.05）. After 6 months of follow-up， the spouses of 5 patients in the treatment group and 3 patients in the control group got pregnant （P＞0.05）. No adverse events occurred in both groups during the treatment， and their vital signs were stable. ConclusionSBYD can obviously improve sperm vitality and effectively improve the clinical symptoms， anxiety and depression， and is safe in treating asthenospermia and infertility with liver constraint and kidney deficiency.

Objective To analyze the risks and related influencing factors of early screening for lung cancer,and to study prognostic factors based on survival conditions,in order to ultimately provide baseline data for the prevention and treatment of lung cancer.Methods A cluster sampling method was used to select 40 to 75 year old registered residence residents in 10 districts and 6 counties of Zhengzhou City in 2020 as screening objects.Through voluntary participation and filling in evaluation questionnaires,high-risk groups of lung cancer were evalu-ated,and then three screening tests(tumor markers,low-dose spiral CT and lung function)were performed on high-risk groups.Finally,we will adopt an active and passive follow-up approach to collect information on diag-nosed lung cancer patients.Statistically describe the screening data and describe the epidemiological results of different characteristic populations;Using multivariate logistic regression method for statistical analysis,compare the differences in various results of different factors.Results 50128 cases of early screening for lung cancer in Zhengzhou City were evaluated in 2020,with a completion rate of 100.26%.The average age of the survey was(59.86±17.67)years old,and the gender ratio was 0.81∶1.The high-risk detection rate is 30.15%.Multivariate logistic regression analysis showed that males(smoking)(OR=5.43,95%CI:5.20～5.67),individuals with a history of tobacco exposure(OR=3.82,95%CI:3.67～3.98),first-degree relatives who had previously suffered from lung cancer(OR=12.06,95%CI:11.02～13.20),and other populations were more susceptible to lung cancer(all P<0.05).Conclusion Male(smoking),exposure to secondhand smoke,cancer in first-degree relatives,previous diagnosis of other tumors,symptoms of lung infection,"chest tightness,shortness of breath,and difficulty breathing in daily life",and"significant psychological trauma in the past 3 years"are independent risk factors for lung cancer,which should be given special attention and effective intervention measures should be taken.

Objective We aimed to investigate the effect of ferroptosis on Shenling Baizhu Powder,a compound prescription of Chinese herbal medicine,in improving testicular spermatogenic function in hyperuricemic mice with spermatogenic dysfunction. Methods Sixty BALB/c mice were randomly divided into normal group,model group,Shenling Baizhu Powder high-,medium-,and low-dose groups (20.14,10.07,5.04 g/kg,by gavage),and ferrostatin-1(Fer-1) group (0.8 mg/kg,by tail vein injection),with 10 mice each group. Except for the normal group,the other groups were intraperitoneally injected with potassium oxonate suspension[600mg/(kg·d)]for 7 days to establish the hyperuricemic model,and then the corresponding intervention was given for consecutive 14 days. Content of serum uric acid (UA),testicular Fe2+,reduced glutathione (GSH),malondialdehyde (MDA) and superoxide dismutase (SOD) activity were detected by biochemical method. Epididymal and testicular indices were measured. The spermatogenic function of testes was evaluated by eosin-hematoxylin staining. Sperm quality was detected by an automatic animal sperm analyzer. Prussian blue staining was used to detect iron deposition in testicular tissue. Immunohistochemistry was used to detect the related protein expressions of acyl-coenzyme A synthetase long-chain family member 4 (ACSL4) and glutathione peroxidase 4 (GPX4) in testicular tissue. Western blotting was used to detect the related protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1(HO-1)/GPX4 signaling pathway in testicular tissue. Results Compared with the normal group,the contents of serum UA,MDA,and Fe2+in the testis tissue of the model group were increased,the GSH content and SOD activity were decreased,the epididymal and testicular index,testicular spermatogenic function,sperm density and activity rate were decreased,and the iron deposition and ACSL4 protein expression in the testis tissue were increased. The expressions of kelch-like ECH-associated protein-1 (Keap1) and Nrf2 were increased. The expressions of nuclear Nrf2,HO-1,GPX4,and recombinant solute carrier family 7 member 11 (SLC7A11) protein were decreased (P<0.01). Compared with the model group,the above indexes in the Shenling Baizhu Powder groups and the Fer-1 group were improved to varying degrees (P<0.05,P<0.01). Conclusion Shenling Baizhu Powder can inhibit the ferroptosis of testicular cells through the Nrf2/HO-1/GPX4 signaling pathway,and improve the testicular spermatogenic function of mice with hyperuricemia spermatogenic dysfunction.

Objective:To investigate the biofilm genes and quorum sensing genes of carbapenem resistant Acinetobacter baumannii (CRAB) in the wounds of diabetic foot patients. Methods:This study was a retrospective observational study. The 233 strains of Acinetobacter baumannii were cultured from 177 inpatients (128 males and 49 females, aged (56±10) years) with diabetic foot admitted to the Department of Diabetic Foot of Tianjin Medical University Chu Hsien-I Memorial Hospital from October 2020 to September 2023. Two hundred and thirty-three Acinetobacter baumannii strains were detected by bacterial culture from the diabetic foot wounds of the aforementioned patients. All Acinetobacter baumannii strains were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, followed by analysis of their resistance rate using kinetic turbidimetric assay by a fully automated microbiological analysis system. Ten CRAB strains (from 10 patients, 9 males and 1 female, aged (63±13) years) and 10 carbapenem sensitive Acinetobacter baumannii (CSAB; from 10 patients, 8 males and 2 females, aged (63±9) years) strains were randomly selected, and the whole DNA genome was extracted and sequenced. The antibiotic resistance genes were annotated using a comprehensive antibiotic resistance gene database, and a phylogenetic tree was drawn to analyze the homologous relationship between CRAB and CSAB. The 7 housekeeping genes of Acinetobacter baumannii was entered into the PubMLST website to analyze the multi-locus sequence typing of CRAB and CSAB. All the measured genes were put into the PubMLST website to search for the biofilm genes bap, csuA, csuB, csuA/B, csuC, csuD, csuE, pgaA, pgaB, pgaC, pgaD, bfmR, bfmS, ompA carried by each Acinetobacter baumannii, as well as the quorum sensing genes abaI and abaR, and flagellar gene pilA. The differences in carrying these genes between CRAB and CSAB were compared. The biofilm genes and quorum sensing genes carried by CRAB and CSAB carrying oxacillinase (OXA) resistance gene blaOXA were analyzed. Gross observation was performed to check if there was gel-like membrane-like substance in the diabetic foot wounds infected with CRAB and CSAB, and if so, the microstructure was observed by scanning electron microscope. Results:Among the detected Acinetobacter baumannii, the positive detection rates of CSAB, CRAB, multi-drug resistant Acinetobacter baumannii, and pan-drug resistant Acinetobacter baumannii were 16.7% (39/233), 83.3% (194/233), 95.3% (222/233), and 34.3% (80/233), respectively, and no fully drug-resistant Acinetobacter baumannii was detected. Among 233 strains of Acinetobacter baumannii, the resistance rate to carbapenem antibiotics exceeded 80%; the resistance rate of cefoperazone/sulbactam was relatively low, at 37%; the resistance rates to the other cephalosporin antibiotics (cefotaxime, ceftazimide, cefotetan, and cefuroxime) were more than 80%; the resistance rates to all penicillin antibiotics were greater than 80%; the resistance rates to quinolone antibiotics were all over 60%; the resistance rate to minocycline was only 12%; the resistance rates to tigecycline and colistin did not exceed 1%. The phylogenetic tree showed that 10 CRAB strains were highly homologous, while 10 CSAB strains had low homology. The analysis of multi-locus sequence typing showed that 10 CRAB strains were all the same type; among the 10 CSAB strains, except 1 strain without typing, the remaining 9 CSAB strains had 7 types. Eight of 10 CRAB strains contained complete biofilm genes and quorum sensing genes. The biofilm genes from the strains of CSAB were incomplete and none carried the bap gene. Neither CRAB nor CSAB carried the flagellar gene pilA. Compared with that carried by CRAB, biofilm genes bap, csuA, csuC, and csuD and quorum sensing genes abaI and abaR carried by CSAB were significantly decreased ( P<0.05). The main blaOXA categories carried by CRAB were blaOXA-23-like (specifically BlaOXA-167) and blaOXA-51-like (specifically blaOXA-66), both of which had carbapenase activity. Eight of 10 CRAB strains carried both blaOXA-66 and blaOXA-167, and all of them had relatively complete quorum sensing genes and biofilm genes. The main blaOXA categories carried by CSAB were blaOXA-51-like and blaOXA-213-like. Although they had carbapenemase activity, clinical drug sensitivity test showed that they were all sensitive to carbapenem antibiotics. Gel-like and membrane-like substance could be seen in wounds infected with CRAB, which were biofilm; no gel-like and membrane-like substance was found in the wound infected with CSAB. Conclusions:CRAB and CSAB in diabetic foot wounds are significantly different in terms of multi-locus sequence typing, carrying biofilm genes, quorum sensing genes, and blaOXA gene, leading to differences in antibiotic resistance between the two.

ObjectiveTo investigate the effect and mechanism of Shenling Baizhusan on the treatment of oligoasthenospermia with hyperuricemia （HUA）. MethodThirty-two male Kunming （KM） mice were randomly divided into blank group （n=6）， model group （n=6）， high-dose Shenling Baizhusan group （n=7）， low-dose Shenling Baizhusan group （n=7）， and febuxostat group （n=6）. Except for the blank group， all other groups received intraperitoneal injection of potassium oxazinate suspension （600 mg·kg^-1） for 7 days. After modeling， the high-dose Shenling Baizhusan group and the low-dose Shenling Baizhusan group were orally administered with 20.14 g·kg^-1 and 10.07 g·kg^-1 of Shenling Baizhusan， respectively. The Febuxostat group was orally administered with 0.25 g·kg^-1 of Febuxostat， while the blank group and model group were orally administered with the same volume of physiological saline. Oral administration was performed once a day for 14 consecutive days， after which samples were collected. Biochemical methods were used to measure serum uric acid （UA）， superoxide dismutase （SOD） and malondialdehyde （MDA） in testicular tissue. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in testicular tissue and evaluate the spermatogenesis function. Automated sperm analyzer was used to measure sperm density and motility. Single-cell gel electrophoresis （SCGE） was used to assess sperm DNA integrity. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling （TUNEL） was used to detect testicular cell apoptosis rate. Western blot analysis was performed to measure the protein expression levels of Kelch-like ECH-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and Caspase-3 in testicular tissue. Real-time polymerase chain reaction （PCR） was conducted to evaluate the mRNA expression levels of Keap1， Nrf2， and HO-1 in testicular tissue. ResultCompared with the blank group， the model group showed elevated serum UA level （P<0.01）， decreased testicular spermatogenesis function， sperm density， and motility （P<0.01）， and increased sperm trailing rate and testicular cell apoptosis rate （P<0.01）. Compared with the model group， the high-dose Shenling Baizhusan group showed significant improvements in the above-mentioned indicators （P<0.05， P<0.01）. Additionally， the expression levels of Keap1， Bax， and Caspase-3 in testicular tissue were reduced， while the expression levels of Nrf2， HO-1， and Bcl-2 increased （P<0.05， P<0.01）. The mRNA level of Keap1 decreased （P<0.05， P<0.01）， while the mRNA levels of Nrf2 and HO-1 increased （P<0.05， P<0.01）. ConclusionShenling Baizhusan can significantly improve HUA oligoasthenospermia， and its mechanism may be related to the Nrf2/antioxidant response element （ARE） signaling pathway.
