Background:Following the short-term outbreak of coronavirus disease 2019(COVID-19)in December 2022 in China,clinical data on kidney transplant recipients(KTRs)with COVID-19 are lacking.Methods:We conducted a single-center retrospective study to describe the clinical features,complications,and mortality rates of hospitalized KTRs infected with COVID-19 between Dec.16,2022 and Jan.31,2023.The patients were followed up until Mar.31,2023.Results:A total of 324 KTRs with COVID-19 were included.The median age was 49 years.The median time between the onset of symptoms and admission was 13 d.Molnupiravir,azvudine,and nirmatrelvir/ritonavir were administered to 67(20.7%),11(3.4%),and 148(45.7%)patients,respectively.Twenty-nine(9.0%)patients were treated with more than one antiviral agent.Forty-eight(14.8%)patients were treated with tocilizumab and 53(16.4%)patients received baricitinib therapy.The acute kidney injury(AKI)occurred in 81(25.0%)patients and 39(12.0%)patients were admitted to intensive care units.Fungal infections were observed in 55(17.0%)patients.Fifty(15.4%)patients lost their graft.The 28-d mortality rate of patients was 9.0%and 42(13.0%)patients died by the end of follow-up.Multivariate Cox regression analysis identified that cerebrovascular disease,AKI incidence,interleukin(IL)-6 level of>6.8 pg/mL,daily dose of corticosteroids of>50 mg,and fungal infection were all associated with an increased risk of death for hospitalized patients.Conclusions:Our findings demonstrate that hospitalized KTRs with COVID-19 are at high risk of mortality.The administration of immunomodulators or the late application of antiviral drugs does not improve patient survival,while higher doses of corticosteroids may increase the death risk.

Objectives:To investigate the clinical features and imaging characteristics of paralytic scoliosis secondary to spinal cord injury due to back-bend movements in dance training.Methods:The clinical and imaging data of patients with paralytic scoliosis secondary to spinal cord injury caused by back-bend move-ments in dance training who were admitted and treated surgically in Nanjing Drum Tower Hospital(division of spine surgery,department of orthopedic surgery)from June 2016 to August 2023 were retrospectively analyzed.All the patients underwent anteroposterior and lateral full spine X-ray examinations in sitting position.The ages of patients at the time of spinal cord injury,diagnosis of scoliosis and surgery were recorded.The planes of paraplegia,types of scoliosis,levels of involved segments,rotation of the apical vertebra,and pres-ence of hip dislocation were analyzed.The Cobb angle of the main curve of coronal scoliosis,pelvic obliquity angle(POA),and the angle of kyphosis were measured on anteroposterior and lateral X-ray films,and the flexibility of scoliosis was calculated.The correlation between the POA and Cobb angle of the main curve was analyzed as well.Results:A total of 19 patients were included in the study.All the patients were female aged 5-9 years(6.8±1.1 years)at the time of back-bend in dance causing spinal cord injury,6-11 years(8.6±1.3 years)at the time of diagnosis of scoliosis,and 10-26 years(13.2±3.9 years)at the time of surgery.All the patients were complete paralysis below the injury plane,which was at T10 level in 13 patients,T9 level in 2 patients,and T8 level in 4 patients.The main curve was all long C-type lumbar curvature or thoracolumbar curvature,and the number of segments involved in the main curve was 7-13(9±2),the Cobb angle was 50°-110°(74.2°±14.6°),and the flexibility of the main curve was 30％-54％(41％±10％).The apex rotation classified by Nash-Moe method fell in Ⅳ degree rotation in 12 cases,Ⅲ degree in 6 cases,and Ⅱ degree in 1 case.In sagittal plane,lumbar kyphosis was observed in 15 cases(78.9％);The local kyphosis angle was 27°-47°(34.3°±5.8°),and the lumbar lordosis angle was-47°-55°(-16.9°±34.1°);The thoracic vertebrae showed a compensated kyphosis reduction or even lordosis,with a thoracic kyphosis angle of-10°-25°(10.4°±9.1°).All the patients were complicated with hip subluxation,17(89.5％)patients among which were unilateral,and most were located on the concave side of the main curve;2(10.5％)patients were complicated with bilateral subluxation,which was more serious on the concave side of the main curve.All the patients had pelvic tilt,with a POA of 9°-39°(22.8°±8.4°).Pearson correlation analysis showed that there was a significant correlation between the POA and Cobb angle of main curve(r=0.635,P＜0.05).Conclusions:Pa-tients with paralytic scoliosis secondary to spinal cord injury due to back-bend movements in dance training present with a long C-type lumbar curve or single thoracolumbar curve,which has a large curve span,long segments involvement,severe vertebral rotation,relatively soft deformity,and short compensatory curve at the proximal end of the main curve.All the patients are combined with pelvic tilt and hip subluxation on the concave side of the main curve.Pelvic tilt is positively correlated with the severity of scoliosis.In the sagittal plane,a compensatory decrease in the thoracic kyphosis is manifested,and lumbar or thoracolumbar kyphosis is presented.

Objective:To explore the influencing factors of acute rejection (AR) within one year after pediatric kidney transplantation (KT) and the effect of AR onset time on prognosis.Methods:From January 2011 to October 2021, a total of 112 patients aged under 18 years at the time of transplantation were selected.After excluding 6 of them with early renal non-function caused by non-rejection, 106 cases were examined.There were 63 males and 43 females with the age of 15(12, 16) years.The donors were living related (n=26) and deceased (n=80).According to the presence/absence and onset time of AR, they were assigned into three groups of AR within one year, AR after one year and non-AR.The relevant clinical data of donor/recipient, influencing factors of AR and therapeutic outcomes of AR were retrospectively compared.One-way ANOVA or Kruskal-Wallis test was utilized for comparing 1-year renal function after the occurrence of AR among three groups.With graft-function loss as an end-point event of follow-up, the effects of AR within one year and AR after one year on survival rate and function of graft-kidney were analyzed by Kaplan-Meier survival curve.Results:The median follow-up period of 106 pediatric KT recipients was 35 months.During follow-ups, 19 episodes of AR occurred in 17(16.0%) patients and 89 recipients exhibited no AR episode by the end of follow-up (non-AR group).As for initial AR, 9 episodes of AR occurred within one year (AR within one year group) and 8 episodes of AR after one year (AR after one year group).After anti-rejection treatment, 8 patients (47.1%) achieved full recovery and 6 patients (35.3%) failed to completely normalize and 3 patients (17.6%) developed graft failure.Univariate analysis indicated that, as compared with non-AR group, female recipients, donors aged under 8 years and early postoperative infection with parvovirus B19 were risk factors of AR within one year ( P=0.032, P=0.039, P=0.047).Kaplan-Meier survival analysis revealed that the incidence rates of AR within one year in patients with donors aged under 8 years and early postoperative parvoviral infection were 14.5%(8/55) and 30.0%(3/10) respectively.They were significantly higher than 2.0%(1/51) and 6.3%(6/96) of patients with donors aged above 8 years and those without parvoviral infection ( P=0.012, P=0.004).With graft-function loss as an end-point event of follow-up, Kaplan-Meier survival analysis showed that 10-year kidney graft survival rate in AR within one year and AR after one year groups were 88.9% and 65.6%.Both were significantly lower than that in non-AR group (98.9%).And the inter-group differences were statistically significant ( χ2=4.286, P=0.038; χ2=7.787, P=0.005).However, no significant difference existed in survival rate between AR within one year and AR after one year groups ( P=0.689).One-way ANOVA and Kruskal-Wallis test indicated that estimated glomerular filtration rates at 3/6/12 months after an onset of AR in AR within one year group were (76.8±51.6), (80.6±56.6) and (85.6±40.2) ml·min -1·1.73 m -2.The values of 3/6 months were lower than (125.3±39.2) and (124.7±38.2) ml·min -1·1.73 m -2 in AR after one year group.And the inter-group differences were statistically significant ( P=0.021, P=0.039).The values of 3/6/12 months were lower than (112.2±34.2), (115.3±33.2) and (117.4±30.2) ml·min -1·1.73 m -2 in non-AR group.And the inter-group differences were also statistically significant ( P=0.019, P=0.020, P=0.020). Conclusions:Female recipients, donors aged under 8 years and early postoperative infection with parvovirus B19 may elevate the risks of AR in children within one year of KT.AR within one year affects the survival rate of graft-kidney and renal function.

Age-related ovarian hypofunction includes a decrease in follicle quantity and quality as well as alterations in the ovarian microenvironment，the mechanisms of which are mainly related to mitochondrial dysfunction，free radical and antioxidant systems，telomere and telomerase alterations，and apoptosis，and is one of the major factors contributing to infertility in advanced maternal age （AMA）. Despite the tremendous progress in assisted reproductive technology in recent decades，few breakthroughs have been made in alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA. In recent years，there has been an increasing number of studies on the multi-level and multi-targeted mechanisms of traditional Chinese medicine （TCM） to improve age-related ovarian hypofunction by modulating mitochondrial homeostasis，alleviating oxidative stress，and inhibiting apoptosis，while more high-quality randomized controlled trials have demonstrated the clinical efficacy of TCM in assisted reproductive technology. Given this，this article presented a systematic review of recent research and randomized controlled trials on the mechanism of Chinese medicine active ingredients，single Chinese medicine， and Chinese medicine compounds in delaying age-related ovarian hypofunction，to clarify the current status and shortcomings of the research. This paper provides medication management of TCM for effectively alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA.

There is currently a huge worldwide demand for donor kidneys for organ transplantation. Consequently, numerous marginal donor kidneys, such as kidneys with microthrombi, are used to save patients' lives. While some studies have shown an association between the presence of microthrombi in donor kidneys and an increased risk for delayed graft function (DGF) (McCall et al., 2003; Gao et al., 2019), other studies have demonstrated that microthrombi negatively impact the rate of DGF (Batra et al., 2016; Hansen et al., 2018), but not graft survival rate (McCall et al., 2003; Batra et al., 2016; Gao et al., 2019). In contrast, Hansen et al. (2018) concluded that fibrin thrombi were not only associated with reduced graft function six months post-transplantation but also with increased graft loss within the first year of transplantation. On the other hand, Batra et al. (2016) found no significant differences in the DGF rate or one-year graft function between recipients in diffuse and focal microthrombi groups. To date, however, the overall influence of donor kidney microthrombi and the degree of influence on prognosis remain controversial, necessitating further research.

Objective:To build a sensitive quality index system of dental clinic nursing.Methods:Based on the Donabedian "structure-process-results" three-dimensional quality model, the indicators at all levels of the sensitive quality index system of dental clinic nursing was preliminarily constructed through literature review. The Delphi method was used to develop a system of sensitive quality indicators for dental outpatient care through two rounds of correspondence with 15 experts from the fields of dental care management, oral health care, quality of care management, and health policy.Results:The effective response rates of the two rounds of expert inquiry questionnaires were 100% (15/15), and the average authority coefficient of the experts was 0.93. The Kendall's harmony coefficients of the overall indicators were 0.115 and 0.141, respectively ( P<0.05). A sensitive quality indicator system for dental clinic nursing was finally determined, including 3 primary indicators, 7 secondary indicators and 19 tertiary indicators. Conclusions:The sensitive quality indicator system for dental clinic nursing constructed in this research is scientific and reliable. After verification through future research, it can serve as a basis for improving the quality of dental clinic nursing.

Considering the existing shortages in evaluation criteria, training systems and management modes, administrators from graduate schools of Shanghai Jiao Tong University School of Medicine (SJTUSM) performed reforms and practice for the establishment of tutor teams which should meet the requirements for culturing talented medical graduates in recent years. We have established a multidimensional evaluation criteria system oriented by both representative academic achievements and the quality of graduate students. We have strengthened horizontal cooperation with relevant administrative departments in SJTUSM. We also emphasize the concepts of "training the trainees" coordinated with administrators in the training units to implement reform measures. Herein we have summarized the main reform measures in SJTUSM to constantly improve the quality of postgraduate tutor team and guarantee high-level postgraduate education.

Primary palmar hyperhidrosis (PPH) is a pathologic condition of excessive sweating on hands that has adverse impacts on patients' social activity, professional life, and psychological state. Endoscopic thoracic sympathicotomy (ETS) is by far the treatment choice for PPH with the most stable and durable curative effects, but special attention should be given to the side effects of the surgery, especially compensatory hyperhidrosis (CH). This consensus is the second version of the Chinese Expert Consensus on the Surgical Treatment of PPH by the China Expert Committee on Palmar Hyperhidrosis (CECPH), which was published 10 years ago. This consensus emphasizes the need for special attention and careful assessment of the patients’ feelings, as well as their emotional and mental state, and emphasizes that distress due to palmar sweating and the desire for treatment are prerequisites for diagnosis. It also provides a more nuanced delineation of CH and reviews all new attempts to prevent and treat this side effect. New evidence of the epidemiology, pathogenesis of PPH, and indications for surgery were also assessed or recommended.
