Conclusion The active components of Qizhenziyin mixture may play a role of the treatment of hypogonadism by improving insulin resistance and the expression of testosterone synthetase of Leydig cells.

Objectives:To investigate the safety and efficacy of concomitant mitral valvuloplasty(MVP)and implantation of domestic third-generation magnetically levitated Corheart 6 left ventricular assist device(LVAD). Methods:Clinical data of 13 end-stage heart failure patients who underwent Corheart 6 LVAD implantation and MVP at Central China Fuwai Hospital of Zhengzhou University from October 2021 to March 2023 were retrospectively analyzed.Mortality and complication events during hospitalization and at follow-up were collected,and changes in myocardial injury biomarkers,renal function,hemodynamics,and echocardiographic indices were observed. Results:There were no perioperative deaths and no MVP-related complications in these patients.During a mean follow-up of(14.2±5.6)months,2 patients died due to COVID-19 pneumonia and cardiac arrest respectively,11 cases(84.6%)survived.There were no recurrences of moderate-to-severe mitral regurgitation in the survived patients.Compared with preoperative value,higher cardiac output,lower central venous pressure,pulmonary artery systolic pressure(PASP),and mean pulmonary artery pressure(PAMP)were evidenced at 24 h and 72 h postoperatively,estimated glomerular filtration rate was also reduced at 1 week post operation(all P<0.010).High-sensitive troponin T level was significantly increased at 1 week post operation and then reduced at 1 month post operation,but still not returned to pre-operative level([125.5±281.9]pg/ml at baseline,[1 295.6±654.6]pg/ml at 1 week post operation and[278.0±300.5]pg/ml at 1 month post operation).Echocardiography showed that compared with preoperative period,the left ventricular ejection fraction tended to be higher at 1 and 6 months postoperatively(both P>0.017),whereas left ventricular end-diastolic dimension,PASP,and PAMP were significantly reduced(all P<0.010). Conclusions:Domestic third-generation magnetically levitated Corheart 6 LVAD implantation with concomitant MVP is safe and feasible,there is no recurrence of moderate-to-severe mitral regurgitation,a significant reduction in pulmonary artery pressure,and significant hemodynamic improvement in early to mid-term postoperatively are observed in survived patients.

Objective To analyze epidemiological characteristics and changing trends of common respiratory infectious diseases among 6-19 year-old population in Shenzhen from 2013 to 2021, and to provide a reference for prevention and control. Methods Data of influenza, mumps and varicella reported cases among the population aged 6-19 years in Shenzhen from 2013 to 2021 were collected, and descriptive methods and Joinpoint regression model were used to analyze epidemiological characteristics and trends of incidences. Results Between 2013 and 2022 in Shenzhen, the average annual incidence rates of influenza, mumps, and varicella among the population aged 6-19 years were 961.44/100 000, 157.70/100 000, and 664.34/100 000 respectively. The incidence of influenza showed an upward trend in 10 years, with an annual percent change (APC) of 52.88% (P<0.05). The incidence of mumps and varicella both showed an 'up-down' trend, with an inflection point in 2019. The incidence APC of mumps were 11.51% and -43.49%, respectively (P>0.05), while the incidence APC of varicella were 28.88% and -50.03%, respectively (P<0.05), respectively. From the point of seasonal distribution, the incidence of three infectious diseases all showed bimodal distribution, with peaks in winter (December to January of the following year) and at the turn from spring to summer (April to June). The proportion of reported cases of three infectious diseases among people aged 6-<10 years old exceeded 60%. The proportion of varicella cases among people aged 10-<15 and 15-19 was on the rise. The incidence rate of influenza and varicella in people aged 15-19 years increased fastest, with APCs of 77.89% and 33.00%, respectively (both P<0.05). Conclusions The trend analysis based on Joinpoint regression model displayed that the reported incidence of influenza among people aged 6-19 years in Shenzhen during 2013-2022 showed an upward trend, and the incidence of varicella had an 'up-down' trend. Children aged 6-<10 years old are the main incidence group, and the prevention and control of infectious diseases in primary schools should be further promoted. Meanwhile, the rapid rise in the incidence of respiratory infectious diseases among people aged 15-19 years old and the increase in the proportion of varicella cases among people aged 10-19 years old suggest that intervention should be carried out to address the influential factors such as immunization gaps and concentrated accommodation in the older age group of minors.

Purpose: Tamoxifen showed individual differences in efficacy under different CYP2D6*10 genotypes. Our study evaluated the prognosis of tamoxifen or toremifene in hormone receptor (HR)–positive breast cancer patients under different genotypes. Materials and Methods: CYP2D6*10 genotypes of HR-positive breast cancer patients were determined by Sanger sequencing, and all the patients were divided into tamoxifen group or toremifene group. Results: A total of 268 patients with HR-positive breast cancer were studied. The median follow-up time was 72.0 months (range, 5.0 to 88.0 months). Of these, 88 (32.9%), 114 (42.5%), and 66 (24.6%) patients had C/C, C/T, and T/T genotypes, respectively. Among patients who received tamoxifen (n=176), the 5-year disease-free survival (DFS) rate in patients with C/C and C/T genotype was better than that in patients with T/T genotype, and the difference was statistically significant (p < 0.001 and p=0.030, respectively). In patients receiving toremifene, CYP2D6*10 genotype was not significantly associated with DFS (p=0.325). Regardless of genotypes, the 5-year DFS rate was higher in patients treated with toremifene than in patients with tamoxifen (91.3% vs. 80.0%, p=0.011). Compared with tamoxifen, toremifene remained an independent prognostic marker of DFS in multivariate analysis (hazard ratio, 0.422; p=0.021). For all the 180 patients with CYP2D6*10 C/T and T/T genotypes, the 5-year DFS rate was significantly higher in the toremifene group than in the tamoxifen group (90.8% vs. 70.1%, p=0.003). Conclusion Toremifene may be an alternative adjuvant endocrine therapy for patients with CYP2D6*10 mutant genotypes.

Objective:To investigate the clinical efficacy of arthroscopic limited incision of the articular capsule to repair the glenoid labrum in the treatment of borderline developmental dysplasia of the hip (BDDH) complicated with labral tear.Methods:A retrospective study was conducted to analyze the data of 18 patients with BDDH complicated with labral tear who had been admitted to Department of Orthopaedics, The Second Hospital Affiliated to Suzhou University from January 2016 to December 2019 (observation group). There were 12 males and 6 females with an age of (41.8 ± 8.5) years. Simultaneously, another 18 patients were selected as the control group whose hip development was normal but age and gender were matched with those in the observation group. There were 9 males and 9 females with an age of (43.5 ± 10.3) years. Both groups were treated by arthroscopic limited incision of the articular capsule to repair the glenoid labrum. The 2 groups were compared in terms of modified Harris hip score (MHHS), Hip Outcome Score Activities of Daily Living Subscale (HOS-ADL), and visual analogue scale (VAS).Results:There was no significant difference in the demographic data like age, gender ratio, body mass index, severity of labral tear or time from injury to operation between the 2 groups, indicating comparability between groups ( P>0.05). The observation and control groups were followed up for (38 ± 7) and (43 ± 6) months, respectively. For the observation and control groups, respectively, MHHS was (97.1 ± 3.3) points and (95.4 ± 4.2) points, HOS-ADL (92.6 ± 2.8) points and (91.4 ± 4.1) points, and VAS (0.6 ± 0.5) points and (1.0 ± 0.8) points, all showing no significant difference between groups ( P>0.05). Conclusion:In the treatment of BDDH patients complicated with labral tear, simple arthroscopic limited incision of the articular capsule to repair the glenoid labrum can lead to the same good medium-term efficacy as it can in those with normal hip development.

Objective:To investigate the effect of intensive care unit (ICU) admission model on acute kidney injury (AKI) development and the prognosis in patients with sepsis.Methods:Patients with sepsis admitted to the ICU of Xinjiang Uygur Autonomous Region People's Hospital from January 2019 to July 2020 were retrospectively analyzed. According to the ICU admission model, the patients were divided into emergency group (first admission or emergency transfer from relevant surgical departments) and delayed group (transferred from the general ward due to disease evolution). Patients were divided into AKI group and non-AKI group according to whether AKI was accompanied. The gender, age, underlying diseases, surgical history, heart rate, laboratory test indicators, acute physiology and chronic health evaluationⅡ(APACHEⅡ), sequential organ failure assessment (SOFA), organ failure and acute complications were collected. The incidence of AKI, 28-day mortality and length of ICU stay were recorded. Univariate and multivariate Logistic regression was used to analyze the risk factors of AKI in patients with sepsis.Results:A total of 185 patients with sepsis were enrolled, including 96 cases in the emergency group and 89 cases in the delayed group. 119 cases of AKI occurred while 66 cases without AKI development. The incidence of AKI within 7 days and the 28-day mortality of patients in the delayed group were significantly higher than those in the emergency group [AKI incidence rate: 77.53% (69/89) vs. 52.08% (50/96), 28-day mortality: 24.72% (22/89) vs. 10.42% (10/96), both P < 0.05], and the length of ICU stay was significantly longer than that of the emergency group (days: 18.70±7.29 vs. 14.56±4.75, P < 0.05). Univariate Logistic analysis showed that there were significant differences in age, diabetes, hypertension, organ failure, heart failure, APACHEⅡscore, SOFA score, white blood cell count (WBC), absolute neutrophil value, platelet count (PLT), blood lactate, total bilirubin, and ICU transferred from general wards between AKI group and non-AKI group. Multivariate Logistic regression analysis showed that transfer from general ward to ICU due to disease evolution was an independent risk factor for AKI in ICU sepsis patients [odds ratio ( OR) = 5.165, 95% confidence interval (95% CI) was 3.911-6.823, P < 0.001]. Conclusion:Septic patients transferred from general ward to ICU due to disease evolution are more likely to develop AKI, and also had a higher mortality and longer ICU stay. It may be an independent risk factor for AKI complicated by patients with sepsis in ICU.

Objective:To explore the efficacy and safety of intraarterial microguidewire electrocoagulation in arterial aneurysms.Methods:(1) SilverSpeed, a kind of microguidewire used in clinical intravascular treatment for intracranial aneurysms, was used to conduct in vitro electrolysis gas generation experiment with isolated arterial blood of anticoagulant New Zealand white rabbits as medium, and thrombus attachment on the surface of microguidewire was observed under scanning electron microscope. (2) Rabbit common carotid artery aneurysm models were established by using vein bag transplantation method, and divided into microguidewire electrocoagulation treatment groups ( n=40) and blank control group ( n=10). The number of closured tumor cavity and the quality of formed thrombus were observed after electrocoagulation simulation treatment with SilverSpeed microguidewire (charging at 6, 9, 12, 15, and 18 V voltage, respectively for 1, 3, 6, 9, 12, and 15 min). DSA was used to observe whether there was ruptured aneurysms or thrombosis of parent artery. Twelve h later, head MRI diffusion weighted sequence scan was performed to detect whether there were new cerebral ischemia foci in the distal cerebral blood supply area of the parent artery. DSA was performed again 6 months after surgery to observe whether the aneurysms recurred. Results:(1) Electrolytic gas generation experiment results showed that bubbles were generated after electrification of SilverSpeed microguidewire; the higher the voltage, the more severe the reaction. Scanning electron microscope showed that thrombus attached to the surface of the microguidewire after electrification in isolated blood; and the higher the voltage, the denser the thrombus. (2) Under the same charging time, the higher the voltage, the larger the number of closured tumor cavity in rabbits of the microguidewire electrocoagulation treatment groups. Under the same voltage, the longer the charging time, the better the quality of thrombosis. Ischemic events occurred only in the microguidewire electrocoagulation treatment group with voltage>9 V, and the charging duration was not associated with the incidence of embolic events. When the voltage was 15 V, 2 experimental rabbits died due to aneurysm rupture 3 min after electrification. When the voltage was 18 V, 4 experimental rabbits died of cardiac arrest 9 min after electrification, and another 2 rabbits died of aneurysm rupture 6 min after electrification.Conclusions:High voltage is the main cause of adverse events in the microguidewire electrocoagulation treatment of aneurysms. After setting the appropriate voltage, prolonging the electrification time can improve the electrocoagulation effect without increasing the safety risk.

Tripartite motif (TRIM) family proteins are important effectors of innate immunity against viral infections. Here we identified TRIM35 as a regulator of TRAF3 activation. Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon (IFN) in response to viral infection. Trim35-deficient mice were more susceptible to influenza A virus (IAV) infection than were wild-type mice. TRIM35 promoted the RIG-I-mediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1. IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3. TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2, thereby antagonizing its suppression of TRAF3 activation. Our in vitro and in vivo findings thus reveal novel roles of TRIM35, through catalyzing Lys63- or Lys48-linked polyubiquitination, in RIG-I antiviral immunity and mechanism of defense against IAV infection.
