Objective To evaluate the application value of fascial platform versus commercial platform in transumbilical single-port laparoscopic transabdominal preperitoneal repair(TAPP)for inguinal hernia.Methods One hundred patients with inguinal hernia admitted between January and December 2024 were prospectively enrolled and randomly assigned to either the fascial platform group(n=50)or the commercial platform group(n=50)by using a random number table.The following parameters were compared between the two groups:platform establishment time,operative time,intraoperative blood loss,incision suture time,operative difficulty score,camera manipulation difficulty score,postoperative 24-hour Visual Analogue Scale(VAS)score of pain,postoperative hospital stay,total hospitalization cost,comprehensive satisfaction score,and postoperative complications.Results The fascial platform group demonstrated significantly superior outcomes compared to the commercial platform group in platform establishment time[(3.4±1.0)min vs.(8.1±1.5)min,t=-18.389,P＜0.001],operative time[(67.5±7.9)min vs.(72.2±11.5)min,t=-2.380,P=0.019],intraoperative blood loss[(8.3±4.3)ml vs.(11.1±5.7)ml,t=-2.798,P=0.006],incision suture time[(7.0±1.4)min vs.(11.8±2.7)min,t=-11.212,P＜0.001],operative difficulty score(14.4±3.6 vs.23.1±4.1,t=-11.215,P＜0.001),camera manipulation difficulty score(11.4±2.6 vs.18.3±2.5,t=-13.370,P＜0.001),VAS score of postoperative 24-hour pain(2.4±1.0 vs.3.7±1.1,t=-6.139,P＜0.001),total hospitalization cost[(15.8±1.6)thousand yuan vs.(18.3±1.6)thousand yuan,t=-7.841,P＜0.001],and comprehensive satisfaction score(7.3±1.1 vs.6.3±1.0,t=5.271,P＜0.001).However,there were no statistically significant differences in postoperative hospital stay or postoperative complication between the two groups(P＞0.05).All the patients were followed up for 1-12 months postoperatively[(5.3±1.8)months vs.(5.7±2.0)months,t=-0.945,P=0.347],with no recurrence observed in either group.Conclusions Both fascial platform and commercial platform can be used for transumbilical single-port TAPP.The fascial platform offers advantages including shorter platform establishment time,reduced incision suture time,lower operative and camera manipulation difficulty,decreased cost,less postoperative pain,and higher patient satisfaction.

Objective To investigate the prediction of natural killer(NK)cells,and T helper cells(Th)cy-tokine levels for assisted reproductive pregnancy outcomes in high-risk human papillomavirus(HR-HPV)in-fected patients.Methods A total of 128 cases of HR-HPV infected patients who received assisted reproduc-tive treatment in a hospital from September 2021 to June 2023 were selected as the study objects,and were di-vided into normal pregnancy outcome group(n=87)and adverse pregnancy outcome group(n=41)accord-ing to their pregnancy outcomes.The clinical data,NK cell proportion,interleukin(IL)-2,IL-4,IL-6 and IL-10 levels before in vitro fertilization-embryo transfer treatment were collected and compared between the two groups.Spearman correlation analysis,univariate Logistic regression analysis and multiple Logistic regression analysis were used to screen out the risk factors for adverse pregnancy outcomes in HR-HPV infected patients receiving assisted reproduction.Receiver operating characteristic(ROC)curve and area under the curve(AUC)were used to evaluate the predictive efficacy of risk factors alone and in combination for adverse preg-nancy outcomes in HR-HPV infected patients undergoing assisted reproduction.Results The age of the ad-verse pregnancy outcome group was significantly higher than that of the normal pregnancy outcome group,and the difference was statistically significant(P＜0.05).The proportion of NK cells and the level of IL-10 in the adverse pregnancy outcome group were significantly lower than those in the normal pregnancy outcome group,and the level of IL-6 was significantly higher than that in the normal pregnancy outcome group,with statistical significance(P＜0.05).Spearman correlation analysis showed that age and IL-6 level of HR-HPV infection were positively correlated with adverse pregnancy outcome after assisted reproduction(r=0.582,0.341,P＜0.001).The proportion of NK cells and the level of IL-10 were negatively correlated with adverse pregnancy outcomes after assisted reproduction(r=-0.459,-0.359,P＜0.001).Multivariate Logistic re-gression analysis showed that the proportion of NK cells,low level of IL-10 and high level of IL-6 in HR-HPV infected persons were risk factors for adverse pregnancy outcomes after assisted reproduction(P＜0.05).ROC curve analysis results showed that the AUC of NK cell ratio,IL-6 and IL-10 alone and in combination to predict adverse pregnancy outcome after assisted reproduction in HR-HPV infected patients were 0.784,0.711,0.660 and 0.876,respectively.The efficiency of combined prediction using the three indicators was higher than that of independent prediction(Z=3.006,3.211,3.716,P＜0.05).Conclusion The levels of NK cells and Th cytokines have important clinical significance in the prediction of assisted reproductive pregnancy outcome in HR-HPV infected patients.

Objective:To explore the application value of patient data-based real-time quality control (PBRTQC) in enhancing the effectiveness of internal quality control (IQC) management.Methods:From the PBRTQC real-time quality control intelligent monitoring platform integrated with the laboratory information system (LIS), a total of 35,631 test results of red blood cell (RBC) count, white blood cell (WBC) count, and dehydroepiandrosterone sulfate (DHEA-S) were collected from patients of the Department of General Xi'an Area Medical Laboratory Center from August 1, 2023, to April 1, 2024. The platform was used in patient data distribution characteristics test, EWMA real-time quality control chart procedure establishment, performance validation, effect evaluation, best procedure selection, and real-time operation. The performance evaluation indexes of the best PBRTQC procedure establishment, the cut-off limit range, weighting coefficient, cumulative mean, standard deviation (SD), coefficient of variation ( CV) of the EWMA real-time quality control chart, and the cumulative mean, SD, and CV of its internal quality control data in the same period were counted, and at the same time compared with the quality target (1/3TEa). Coefficient of variation analyses were performed to compare the quality control status of PBRTQC and conventional internal quality control in the presence of warning or alarm prompts based on quality control process records, and alarm messages. Results:The evaluation indexes of the optimal procedures for RBC count, WBC count, and DHEA-S were the probability of error detection (Ped) between 93%-97% and greater than 90%, the false positive rate (FPR) between 0.0%-0.5%, the false negative rate (FNR) between 3.0%-7.0%, and the average number of the patient sample until error detection (ANPed) between 5-11, which is in line with the optimal quality control efficacy quality requirements for the PBRTQC procedure. The patient outcome cut-off concentrations for the optimal procedure EWMA quality control charts ranged from RBC count (3.92-5.16)×10 12/L, WBC count (4.28-7.50)×10 9/L, and DHEA-S (830-2 160) μg/L; (2 160-4 210) μg/L. The weighting coefficients were 0.05, 0.03, and 0.03, respectively. The real-world application of the EWMA real-time quality control charts showed stable and excellent analytical performance of the measurement system, such as out-of-control alarm: RBC count, 1 true alarm, Ped of 95.85%, and FPR of 0%. The cumulative CV of EWMA was less than the quality target; the cumulative CV of DHEA-S was 7.66% and 9.47%, respectively, and the cumulative CV of low level was greater than the quality target (8.33%), and the cumulative CV of high and low levels were 4.12% and 6.25%. Conclusion:The PBRTQC EWMA method can monitor the patient data - in real-time and continuous way. It can also dynamically identify and provide early indication of small changes in analytical performance during the analysis process, and can be used as a supplement to quality control products to improve the efficacy of laboratory quality management.

This study was carried out to investigate the pharmacokinetics/bioequivalence of levornidazole disodium phosphate by using stable isotope labeled drug, evaluated the pharmacokinetic profile and confirmed the prodrug characteristics of levornidazole disodium phosphate in monkey. Levornidazole (Drug A) and stable isotope ¹⁵N labeled levornidazole disodium phosphate (Drug B) were mixed with equal mole amount (experiment I); stable isotope ¹⁵N labeled levornidazole disodium phosphate (Drug B) and levornidazole disodium phosphate (Drug C) were mixed with equal mole amount, respectively. After giving the mixed drugs to the monkey, the concentration of ¹⁵N-levornidazole disodium phosphate, levornidazole disodium phosphate, ¹⁵N-levornidazole and levornidazole in plasma samples of pre-dosing and 24 h after administration were analyzed by a liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method. Pharmacokinetic calculations were performed through non-compartmental analysis using WinNonlin software. Two-sided 90% confidence intervals (CI) were used to evaluate the bioequivalence of two drugs. The results showed that levornidazole disodium phosphate was metabolized to levornidazole rapidly after administration, the body exposure were increased with the dosage. The method of bioequivalence used in this study was different from the traditional two periods, crossover design. By using the method of this study, the effects of administration period, intra-individual variability, and sequence of administration on bioequivalence were avoided. The results of this study had successfully supported the pharmacokinetic and bioequivalence study of this drug in human using the same approach.

Objective To investigate the antimicrobial resistance and genotype distribution of staphylococcal cassette chromosome mec (SCCmec) of staphylococcus aureus (S.aureus) isolated from children hospitalized at Pediatric People's Hospital of Zhongjiang County.Methods Seventy-seven strains of S.aureus were collected by nasopharyngeal swabs at the Pediatric Department of People's Hospital of Zhongjiang County from January to December 2015.Methicillin-resistant staphylococcus aureus (MRSA) and methicillin-susceptible staphylococcus aureus (MSSA) were identified by cefoxitin disc diffusion and detection of mecA method.The minimum inhibitory concentrations (MIC) of antibiotics were determined by E-test method.SCCmec typing on MRSA strains was performed by using multiplex PCR.Results MRSA accounted for 54.5％ (42 strains) strains of 77 strains.All MRSA strains were resistant to Penicillin,and the rates of antibiotic resistance to Cefuroxime,Ceftriaxone,Erythromycin were 78.6％,95.2％ and 97.6％,respectively.The rates of antibiotic resistance of 35 MSSA to Penicillin and Erythromycin were 97.1％ and 62.9％,and they were also sensitive to other antibiotics.In 42 strains of MRSA,SCCmec type Ⅳa was the predominant type (27 strains,64.3 ％),which was followed by type Ⅳ g and Ⅴ (each 5 strains,11.9％),type Ⅳ c and Ⅳh (each 1strain,2.4％).Non-susceptibility rate of SCCmec Ⅳ to cefuroxime was significantly higher than that of other SCCmec types (P ＜ 0.05).Conclusions All strains from children hospitalized in People's Hospital of Zhongjiang County are often resistant to Penicillin and Erythromycin.The proportion of MRSA isolated from hospitalized children was high.SCCmec type Ⅳa is the main genotype of MRSA.

Objective To investigate the effects of Tangshen Formula on liver oxidative stress in diabetic rats, and their mechanisms thereof.Methods Rat model of type 2 diabetes mellitus and nonalcoholic fatty liver disease was estab?lished by intraperitoneally injecting small dose of chain urea with cephalosporins (STZ) and feeding high fat fodder . The model rats were randomly divided into control group, model group, Tangshen Formula group and metformin group.The se?rum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol (CHO), low density lipoprotein-cholesterol(LDL-C), and superoxide dismutase (SOD), catalase(CAT), vitamin E(VE), nitric oxide (NO) and nitric oxide synthase (NOS) in liver were compared between four groups. Changes of pathological morphology were ob?served under light microscopy. Results There were significantly decrease in serum levels of ALT, AST, TG, CHO, LDL-C in Tangshen Formula group and metformin group compared with those of model group. There were significantly higher levels of SOD, CAT and VE, and lower levels of NO and NOS of liver homogenate in Tangshen Formula group than those of model group. There were higher levels of SOD and CAT, and lower levels of NO and NOS in liver homogenate in metformin group than those of model group. HE staining showed that liver fatty degeneration was significantly reduced in metformin group and Tangshen Formula group compared with that of model group. Conclusion The fatty liver in type 2 diabetic rats is signifi?cantly improved by Tangshen Formula treatment, which is probably associated with the regulation of the response level to oxi?dative stress in liver.
