OBJECTIVE To understand the drug resistance among the acquired immune deficiency syndrome(AIDS)population who failed in the antiviral therapy from 2022 to 2023 and analyze the molecular network.METHODS The plasma specimens were collected from the population with viral load no less than 1000 cps/ml who received antiviral therapy for more than 6 months in Aksu area from 2022 to 2023,which were delivered to Aksu Regional Center for Disease Control and Prevention for test.MEGA5 and the Stanford University drug resistance database were employed to determine the subtypes and drug resistance after the sequences of human immunodefi-ciency virus type Ⅰ polymerase gene region(HIV-1pol)were obtained,and the molecular network was established by HIV-trace.RESULTS Totally 648 sequences of HIV-1pol region were obtained,CRF07_BC(97.69％)was the major subtype,and the drug resistance rate was 58.33％;the drug resistance rates to non-nucleoside reverse transcriptase inhibitor(NNRTI),nucleoside reverse transcriptase inhibitor(NRTI)and protease inhibitor(PI)were 51.70％,19.75％and8.64％,respectively.The univariate analysis showed that year(x2=6.341),age(x2=18.455)and route of infection(x2=14.061)had remarkable effects on the drug resistance among the population with failed ART(P＜0.05).Multivariate regression analysis indicated that the drug resistance rate was higher in 2022 than in 2023(95％CI:1.132 to 2.191),and the drug resistance rate was higher among the population aged less than 60 years old than among the population more than 6 years old(95％CI:3.647 to 70.268,95％CI:1.435 to 8.235,95％CI:1.061 to 6.164,re-spectively).With 1.5％of the genetic distance set as the threshold,the molecular network was established,the network access rate was 49.07％,77.14％of the clusters had drug-resistant mutation sites,and the male population was at higher risk of network access than the female population.CONCLUSIONS The drug resistance rate is relatively high among the AIDS population with failed ART,and the drug-resistant strains appear in clusters in the molecular network.It is neces-sary to further strengthen the monitoring of drug resistance and improve the quality of the follow-up so as to reduce the occurrence of drug resistance and transmission of virulent strains.

Objective To discuss the mechanism of the streaking artifact of Star-volumetric interpolated body examination(Star-VIBE)sequence and the influence of phase coding on it.Methods Twenty-six volunteers underwent many times Star-VIBE sequences scanning with different phase coding(320,640,960,1 280,1 600).The severity of streaking artifact of images in different phase cod-ing groups was evaluated qualitatively.The signal-to-noise ratio(SNR)of muscle,thyroid and contrast-enhanced artery,contrast-to-noise ratio(CNR)between soft tissues,and CNR between muscle and contrast-enhanced artery of the images in different phase coding groups were evaluated quantitatively.Results In qualitative evaluation,with the number of phase coding increased,the streaking artifact decreased(H=83.022,P＜0.005).In quantitative evaluation,SNRmuscle,SNRthyroid,SNRcontrast-enhanced artery and CNRcontrast-enhanced gradually increased with the increase of phase coding number(SNRmuscle:F=6.913,P＜0.005;SNRthyroid:F=3.930,P=0.005;SNRcontrast-enhanced artery:F=6.980,P＜0.005;CNRcontrast-enhanced:F=6.482,P＜0.005),while CNRsoft tissue showed no statistical difference(F=1.114,P=0.339).Conclusion There is streaking artifact on the image of the Star-VIBE sequence,which can be reduced by increas-ing the number of phase coding appropriately.The most suitable phase coding is 960.

Objective To explore the effect of Rhizoma Polygonati(RP)on arterial aging in naturally aging Wistar rats.Methods SPF Wistar rats aged 72 weeks were divided randomly divided into 4 groups:an old group and RP low,medium,and high-dose groups(n=14 rats per group).Another 14 male SPF Wistar rats aged 8～12 weeks were selected as the young group.Rats in the RP high,medium,and low-dose groups were administered with 4,2,and 1 g/kg RP,respectively,by gavage,and rats in the old and young groups were given the same amount of distilled water once a day for 12 weeks.Seven rats from each group were sacrificed under anesthesia at weeks 4 and 12 and aortas were isolated.The relative smooth muscle cell(SMC)and collagen fiber(CF)contents were analyzed,total antioxidant capacity(T-AOC),glutathione peroxidase(GSH-Px),superoxide dismutase(SOD),and malondialdehyde(MDA)levels were measured,and the expression levels of cell cycle-associated proteins in arterial tissue were detected by Western Blot.Results Rats in the old group showed obvious signs of vascular aging but there was no significant changes in arterial vascular tissue indexes in the old group with increased age.Aortas were obviously injured,relative contents of SMC and CF were significantly increased(P＜0.01),T-AOC,SOD,and GSH-Px contents were significantly decreased and MDA was increased(P＜0.01)in the old group compared with the young group at 4 and 8 weeks,and expression levels of cell cycle-associated proteins were significantly up-regulated(P＜0.01).RP intervention significantly decreased the relative SMC and CF contents and MDA levels(P＜0.05 or P＜0.01)and significantly increased T-AOC,SOD,and GSH-Px(P＜0.05 or P＜0.01).Expression levels of cell cycle-associated proteins were also significantly decreased(P＜0.05 or P＜0.01).High-dose RP had the greatest effect.Conclusions Arterial aging is relatively stable in the short term in naturally aging rats.RP could delay arterial aging in naturally aging rats by regulating the level of oxidative stress and the expression of cell cycle-associated proteins.

Objective To evaluate the efficacy of non-ablative vaginal erbium-doped yttrium aluminum garnet(Er:YAG)laser therapy in improving symptoms in women with mild-to-moderate stress urinary incontinence(SUI).Methods A prospective,multicenter,randomized controlled trial was conducted.A total of 126 female SUI patients were enrolled and randomized in a 2∶1 ratio to the treatment group(n=84,receiving Er:YAG laser therapy)and the sham control group(n=42,undergoing non-energized laser device with shielded beam).Efficacy outcomes were compared between the two groups,including the International Consultation on Incontinence Questionnaire-Short Form(ICI-Q-SF)scores at baseline and 1,3,6 months after treatment,response rate 3 month after treatment,urine leakage volume,daily incontinence episodes and visual analog scale(VAS).Results One month and 3 months after treatment,the ICI-Q-SF scores in the treatment group(8.07±3.33 and 7.04±3.04,respectively)were significantly lower than those in the control group(9.57±4.03 and 9.65±3.27,respectively;both P＜0.05).The 3-month response rate was significantly higher in the treatment group(71.43％)compared to the control group(35.71％,P＜0.05).Improvements in urine leakage volume 1 and 3 months after treatment were significantly greater in the treatment group versus the control group(both P＜0.05).A statistically significant reduction in daily incontinence episodes was observed in the treatment group 1 month after treatment compared to the control group[2(0,5)times vs.4(2,8)times,P＜0.05].VAS score in the treatment group markedly decreased 1 month after treatment,comparable to the level observed in the control group[0(0,2.45)vs.0(0,0),P＜0.05].Conclusion Non-ablative vaginal Er:YAG laser therapy significantly alleviates symptoms in women with mild-to-moderate SUI and represents a viable treatment option for this condition.

Objective:To investigate the effect of chrysophanol(CHR)on cartilage injury in rats with osteoarthritis and its mechanism of regulating SIRT1/HMGB1/NF-κB signal pathway.Methods:Rat models of osteoarthritis were established and divided into negative control group,chrysophanol low(CHR-L,10 mg/kg),middle(CHR-M,20 mg/kg),high dose group(CHR-H,40 mg/kg),SIRT1 inhibitor(sirtinol 5 mg/kg)+chrysophanol high dose group(sirtinol+CHR-H),and normal healthy control group was set up.The degree of joint swelling was measured,and the inflammatory index was evaluated;the pain threshold(tenderness and heat pain)was measured;HE staining and safranine O staining were applied to detect the pathological changes of rat articular cartilage;the levels of serum inflammatory factors(IL-6,IL-1β,TNF-α)were detected by ELISA method;oxidative stress indexes(MDA,SOD,GSH-PX)were detected by micro method;TUNEL staining was used to detect apoptosis;Western blot was used to detect the protein expressions of SIRT1,HMGB1,NF-κB p65,p-NF-κB p65,MMP-13 and C-Caspase-3.Results:Compared with the normal healthy control group,the rats in negative control group had obvious pathological injury,such as destruction of articular cartilage structure,necrosis and reduction of chondrocytes,the joint swelling degree,arthritis index,levels of IL-6,IL-1β,TNF-α,content of MDA,chondrocyte apoptosis rate,expressions of apoptotic protein C-Caspase-3,HMGB1,NF-κB p65/p-NF-κB p65,MMP-13 proteins increased obviously,the tenderness threshold,heat pain threshold,activities of SOD,GSH-PX,and the expression of SIRT1 protein decreased obviously(P<0.05);compared with negative control group,the pathological injury of articular cartilage in CHR group improved obviously with the increase of dosage,the joint swelling degree,arthritis index,levels of IL-6,IL-1β,TNF-α,content of MDA,chondrocyte apoptosis rate,expression of apoptotic protein C-Caspase-3,HMGB1,NF-κB p65/p-NF-κB p65,MMP-13 proteins decreased obviously,the tenderness threshold,heat pain threshold,activities of SOD,GSH-PX,and the expression of SIRT1 protein increased obviously(P<0.05);compared with CHR-H group,sirtinol+CHR-H group was able to reverse the protective effect of CHR on cartilage injury to a certain extent.Conclusion:CHR can reduce the inflammation of articular cartilage,inhibit the apoptosis of chondrocytes and play a protective role in the cartilage injury of osteoarthritis rats by up-regulating the expression of SIRT1 and down-regulating the expressions of HMGB1 and NF-κB p65/p-NF-κB p65.

Objective To develop and validate a nomogram model that integrates systemic inflammatory markers to predict the likelihood of pelvic lymph node metastasis(PLNM)in prostate cancer patients prior to surgery.Methods This study retrospectively analyzed the clinical data and preoperative inflammatory markers—including neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),systemic immune-inflammation index(SII),and monocyte-to-lymphocyte ratio(MLR)—of patients diagnosed with prostate cancer.Univariate and multi-variate logistic regression analyses were conducted to identify markers that were significantly associated with PLNM.Based on the results of the multivariate analysis,a nomogram was developed and its predictive accuracy was assessed using receiver operating characteristic curves(ROC)and calibration plots.Results Among the 334 enrolled patients with prostate cancer,107 were identified with PLNM.Univariate analysis revealed statistically significant differences in free prostate-specific antigen(fPSA),Gleason score,NLR,PLR,MLR,and SII between the PLNM and non-pelvic lymph node metastasis(NPLNM)groups(P<0.05).Multivariate analysis confirmed that fPSA,Gleason score,and SII were independent predictors of PLNM(P<0.05).A nomogram incorporating these predic-tors exhibited strong discriminative ability,with an area under the ROC curve(AUC)of 0.79(95%CI:0.73～0.84).Calibration analysis further demonstrated good consistency between the predicted and observed probabilities of PLNM.Conclusions This study successfully developed a nomogram model based on systemic inflammatory markers for preoperative prediction of pelvic lymph node metastasis in prostate cancer.Owing to its user-friendly design and high predictive accuracy,this tool may serve as a valuable complementary method to conventional imaging techniques,thereby supporting personalized treatment decision-making.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

The use of CD20 monoclonal antibody in the treatment of children with refractory nephrotic syndrome (RNS) is a novel drug therapy in recent years. Some CD20 monoclonal antibodies have positive efficacy and few adverse reactions, which can reduce the use of hormone drugs and immunosuppressants to a certain extent. However, the treatment of nephrotic syndrome is off-label, and the application time in clinic is not long, especially for children′s RNS, and more high-quality clinical studies are still needed for long-term efficacy and safety. The application and safety research progress of CD20 monoclonal antibody (including rituximab, ofatumumab, obinutuzumab, etc.) in the treatment of children with RNS from the aspects of mechanism of action, clinical application, pharmacokinetic characteristics, adverse reactions monitoring, and prevention are reviewed in this article, so as to provide reference for rational and safe clinical use.
