Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Glyceryl phenylbutyrate(GPB)serves as a long-term management medication for Ornithine transcarbamylase deficiency(OTCD),effectively controlling hyperammonemia,but there is a lack of experience in using this medicine in China.This article retrospectively analyzes the case of a child diagnosed with OTCD at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,including a review of related literature.After diagnosis,the patient was treated with GPB,followed by efficacy follow-up and pharmacological monitoring.The 6-year and 6-month-old male patient exhibited poor speech development,disobedience,temper tantrums,and aggressive behavior.Blood ammonia levels peaked at 327 μmol/L;urine organic acid analysis indicated elevated uracil levels;cranial MRI showed extensive abnormal signals in both cerebral hemispheres.Genetic testing revealed de novo mutation in the OTC gene(c.241T＞C,p.S81P).Blood ammonia levels were approximately 43,80,and 56 μmol/L at 1,2,and 3 months after starting GPB treatment,respectively.During treatment,blood ammonia was well-controlled without drug-related adverse effects.The patient showed improvement in developmental delays,obedience,temperament,and absence of aggressive behavior.

Objectives:To evaluate with meta-analysis the clinical effects of physiotherapeutic scoliosis spe-cific exercises(PSSE)comparing with other conservative treatments in treating adolescent idiopathic scoliosis(AIS).Methods:PubMed,Web of Science,The Cochrane Library,WanFang Data and China National Knowl-edge Infrastructure(CNKI)were searched by computer from their establishments to July 2023.The randomized controlled trials(RCTs)of PSSE therapy(PSSE therapy group)and other conservative treatments(control group)in treating AIS were collected.Two researchers independently screened the literature,extracted data and assessed the risk of bias of the included studies.Meta analysis was performed using RevMan 5.4 software on the Cobb angle,angle of trunk rotation(ATR),and quality of life score of Scoliosis Research Society-22(SRS-22)scale reported in the included literature,and subgroup analysis was carried on according to Cobb angle and treat-ment duration.Results:A total of 14 studies were included,consisting of 16 RCTs(2 studies included 2 RCTs each),involving 944 AIS patients.The quality of the literature was of medium and high.Meta analysis results showed that,comparing with the control group,the PSSE therapy group was superior in reducing Cobb angle of AIS patients(MD=1.64;95％CI:2.78,0.50;P＜0.05)and ATR(MD=1.45;95％CI:-2.58,-0.32;P＜0.05),and improving the SRS-22 quality of life score(MD=0.25;95％CI:0.17,0.33;P＜0.05).The results of subgroup analysis showed that for the AIS patients with duration of treatment ≤6 months(MD=-2.88;95％CI:-3.85,-1.91;P＜0.05)and a Cobb angle＜25° at enrollment(MD=-2.41;95％CI:-3.51,-1.30;P＜0.05),the PSSE therapy group had a better effect with a smaller Cobb angle(P＜0.05)than the control group.In terms of ATR improvement,for the patients with treatment duration ≤6 months(MD=2.63;95％CI:3.30,1.96;P＜0.05),the PSSE therapy group had a lower ATR degree comparing with the control group(P＜0.05).Conclusions:Comparing with other conservative treatments,PSSE therapy has advantages in improving the Cobb angle,re-ducing ATR and improving the quality of life in AIS patients,especially for mild scoliosis patients with Cobb angle＜25°.PSSE therapy has a better therapeutic effect on reducing the Cobb angle and ATR more obvious-ly in AIS patients with duration of treatment ≤6 months.

Objective To explore the mechanism of Gualou Xiebai Baijiu Decoction(GXB)in improving atherosclerosis(AS)in mice by regulating the gut microbiota(GM)and its metabolites.Methods Thirty-two male ApoE-/-mice were divided randomly into a Blank group,Model group,atorvastatin(Ato)group,and GXB group(n=8 mice per group).AS was established in all mice,except the Blank group,and the respective treatments were administered by gavage.Aortic plaques were detected by Oil red O staining and pathological changes in aortic tissue were detected by hematoxylin and eosin staining.The GM was analyzed using 16S rRNA gene sequencing technology,and mouse GM metabolites,including trimethylamine oxide(TMAO),short-chain fatty acids(SCFA),and serum levels of triglycerides(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),and nitric oxide(NO)were determined.Results Compared with the Blank group,mice in the Model and Ato groups showed an increase in AS plaque area(P＜0.05).Serum levels of TG,TC,and LDL-C were increased(P＜0.001)while levels of HDL-C and NO were decreased(P＜0.01,P＜0.001)in the Model group compared with the Blank group.The plaque area was decreased(P＜0.05),serum levels of TG,TC,and LDL-C were decreased(P＜0.001),and NO levels were increased(P＜0.01)in the Ato and GXB groups,while HDL-C levels were increased in the GXB group(P＜0.05)compared with the Model group.Plaque area was decreased(P＜0.05)and the NO level was increased(P＜0.01)in the GXB group compared with the Ato group.A total of 6345 characteristic sequences were obtained from 16S rRNA analysis.α-Diversity analysis indicated that GXB reduced the richness of the GM in AS mice(P＜0.001)and improved its uniformity(P＜0.05).β-Diversity analysis suggested that the microbial community structure in the GXB group was similar to that in the Blank group.The abundance of microbial communities differed among the groups at the phylum and genus levels.At the phylum level,the abundance of Proteobacteria was increased(P＜0.01)in AS mice,while GXB intervention reduced the abundance of Proteobacteria(P＜0.01)and increased the abundance of Verrucomimicrobiota(P＜0.05).At the genus level,GXB effectively increased the abundance of Akkermansia(P＜0.05).SCFAs were significantly increased(P＜0.01)and TMAO levels were significantly decreased(P＜0.01)in the GXB group compared with the Model group.Conclusions GXB can regulate the intestinal flora and intestinal flora metabolites SCFA and TMAO to improve AS.Akkermansia may be a key bacterial genus of the gut microbiota through which GXB may improve AS.

Objective:To explore the perioperative nursing methods of autologous dermal transplantation for penile girth en-hancement combined with penile lengthening surgery.Methods:Summarize the perioperative nursing data of 5 patients with small penis who underwent autologous groin dermal transplantation for penile girth enhancement combined with penile lengthening surgery.Results:After comprehensive perioperative nursing,all 5 patients recovered well after the surgery.The preoperative APPSSI scores of the patients were4.60±0.48,which were all less than 6 points.The postoperative APPSSI scores at 2 months,6 months,and 12 months were 9-12(10.6±1.02),10-12(11.2±0.98),and 10-12(11.2±0.98)respectively,showing satisfaction with the surgical outcomes.There was a statistically significant difference compared to the preoperative APPSSI scores(P<0.05).The preop-erative SAS scores were 45-58(52.2±4.35),and the SAS scores at 2 months,6 months,and 12 months postoperatively were 31-40(34.2±3.31),30-41(35.8±3.65),and 33-40(35.6±2.33)respectively,indicating a reduction in anxiety levels after the surgery,with a statistically significant difference compared to the preoperative SAS scores(P<0.05).The preoperative IIEF-5 scores were 7-15(10.4±2.87),and the IIEF-5 scores at 2 months,6 months,and 1 year postoperatively were 16-24(19.8±2.71),18-25(21.2±2.48),and 18-24(20.8±2.39)respectively,showing a significant improvement postoperatively,with statistical significance(P<0.05).The preoperative NPTR examination showed a sustained erection time of 18-25(21.2±2.59)minutes,and the NPTR examination at2 months,6 months,and 1 year postoperatively showed sustained erection times of 18-24(21.8±2.28),20-25(23.4±2.30),and 24-27(25.4±1.14)minutes respectively.There was no statistically significant difference in the sustained erection time at 2 months and 6 months postoperatively compared to preoperative NPTR examination,but there was a statisti-cally significant difference at 12 months postoperatively(P<0.01).Conclusion:Comprehensive perioperative nursing is an impor-tant factor in achieving high satisfaction with the surgery,promoting postoperative recovery,and improving the quality of sexual life for patients undergoing autologous groin dermal transplantation for penile girth enhancement combined with penile lengthening surgery.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

This study was designed to comprehensively characterize and identify the chemical components in traditional Chinese medicine Psoraleae Fructus by establishing an ultra-high performance liquid chromatography/quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS) method in combination with in-house library. The chromatographic separation conditions(stationary phase, column temperature, mobile phase, and elution gradient) and key MS monitoring parameters(capillary voltage, nozzle voltage, and fragmentor) were sequentially optimized via single-factor experiments. A BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) was finally adopted, with the mobile phase consisting of 0.1% formic acid in water(A) and acetonitrile(B) at the flow rate of 0.4 mL·min~(-1) and column temperature of 30 ℃. Auto MS/MS was utilized for data acquisition in both positive and negative ion modes. By comparison with reference compounds, analysis of the MS~2 fragments, in-house library retrieval and literature research, 83 compounds were identified or tentatively characterized from Psoraleae Fructus, including 58 flavonoids, 11 coumarins, 4 terpenoid phenols, and 10 others. Sixteen of them were identified by comparison with reference compounds, and ten compounds may have not been reported from Psoraleae Fructus. This study achieved a rapid qualitative analysis on the chemical components in Psoraleae Fructus, which provided useful reference for elucidating its material basis and promoting the quality control.

This study compared the effects of Curcuma longa before and after processing with vinegar on the rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation to reveal the mechanism of vinegar processing in improving the role of C. longa in soothing liver and relieving pain. The rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation was established according to the Preparation of the Animal Model of Dysmenorrhea(Draft) and the chronic unpredictable stress me-thod. The changes in the body weight, organ indexes, writhing latency, writhing score, and serum levels of six liver function indicators, sex hormones, pain factors, and blood rheological indicators were measured to evaluate the efficacy of C. longa processed with vinegar or not in treating dysmenorrhea in the rats with syndrome of liver depression and qi stagnation. Compared with the model group, the C. longa group(processed with vinegar or not) showed slow weight loss, increase in writhing latency, and decrease in writhing response(P<0.05). The inhibition rates on writhing in raw C. longa, vinegar-processed C. longa, and positive groups were 33.780%, 64.611%, and 62.466%, respectively. The significantly higher inhibition rate of the vinegar processing group indicated that vinegar-processed C. longa demonstrated more significant therapeutic effect. The vinegar-processed C. longa group showed lower levels of alanine aminotransferase(ALT), alkaline phosphatase(ALP), aspartate aminotransferase(AST), direct bilirubin(DBIL), and total bilirubin(TBIL) and higher level of albumin(ALB)(P<0.05), which indicated that vinegar processing enhanced the therapeutic effect of C. longa on liver injury. The serum levels of estradiol(E_2) and oxytocin(OT) were lower in the vinegar-processed C. longa group(P<0.05), indicating that the vinegar-processed C. longa could regulate the sex hormone levels, reduce the activity of uterine smooth muscle and contraction of uterus, and alleviate the symptoms of dysmenorrhea in rats. Moreover, the vinegar-processed C. longa group showed lower interleukin-6(IL-6) and arginine vasopressin(AVP) levels and higher beta-endorphin(β-EP) level(P<0.05), which indicated that vinegar-processed C. longa regulated the levels of pain factors to exert the pain-relieving effect. Drug intervention decreased the whole blood viscosity low-cut, medium-cut and high-cut values, plasma viscosity, whole blood reduction viscosity low-cut and high-cut values, erythrocyte cumulative pressure, and equation K value of erythrocyte sedimentation rate(P<0.05), and the vinegar-processed C. longa group outperformed other groups. This result indicated that vinegar processing enhanced the function of C. longa in improving the local blood rheology. C. longa processed with vinegar can enter the liver to relieve the da-mage to the heart, liver, kidney, and uterus, repair the liver function, and recover the sex hormone levels and immune function by regulating the levels of sex hormones and pain factors and improving the blood rheology. It activates the pain-relieving mechanism to relieve the pain, protect the liver, and fight inflammation, which is consistent with the theory that vinegar processing facilitates C. longa entering the liver to sooth liver and relieve pain.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.
