ObjectiveTo explore the academic characteristics of contemporary renowned Chinese medicine masters in treating diabetic kidney disease （DKD） from the perspectives of principles， methods， formulas， and medications. MethodsIn strict accordance with the Systematic Review of Text and Opinion （SrTO） process developed by the Joanna Briggs Institute （JBI）， an Australian evidence-based healthcare center， the databases including China National Knowledge Infrastructure （CNKI）， VIP Database， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched. Based on predefined inclusion and exclusion criteria， text information extraction， quality evaluation， and text information synthesis were conducted sequentially. The data were analyzed and presented in the form of text and figures. ResultsA total of 215 articles related to 43 contemporary renowned experts in the fields of Chinese medicine nephrology and endocrinology were included. The study found that the academic thoughts of these masters in the treatment of DKD are extensive， involving multiple levels such as disease understanding， therapeutic strategies， formula application， and medication use. In terms of disease understanding， the primary pathogenesis is characterized by deficiency in the root and excess in the manifestation. It is emphasized that internal factors， such as congenital endowment deficiency， interact with external factors such as improper diet， emotional disturbances， invasion of exogenous pathogens， and delayed or inappropriate treatment， to jointly induce the disease. This further gives rise to various pathogenetic theories， including obstruction of renal collaterals by blood stasis， toxin-induced damage to renal collaterals， latent wind disturbing the kidney， and internal heat leading to mass formation. In terms of therapeutic strategies and medication use， the principal treatment method is to replenish Qi and nourish Yin. Stage-based and syndrome-differentiated treatments are advocated. Flexible use of insect-derived drugs and wind-dispelling drugs is emphasized， along with proficiency in applying classical formulas and drug pairs. Integrated internal and external treatments， as well as the combined application of multiple therapeutic approaches， are commonly employed for comprehensive management. Meanwhile， the concept of "preventive treatment of disease" is upheld， and individualized long-term management of patients is advocated. ConclusionThrough the SrTO process， the academic thoughts of contemporary renowned Chinese medicine masters in the treatment of DKD have been systematically and standardly synthesized， providing a scientific and standardized basis for future theoretical exploration.

Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.

Objective:To investigate the clinical efficacy of Tofacitinib combined with leflunomide in the treatment of rheumatoid arthritis (RA) and its effects on Janus Kinase (JAK)/signal transduction and activator of transcription (STAT) signaling pathway-related proteins and Matrix metalloproteinase levels in serum of patients with RA.Methods:This was a prospective case-control study. A total of 80 patients with RA in our hospital from March 2020 to September 2021 were included into the study. They were divided into observation group and control group by random number table method, with 40 cases in each group. The patients in observation group were treated with Tofacitinib combined with leflunomide, while the patients in control group were treated with leflunomide alone. After 12 weeks of continuous treatment, the curative effect of the two groups was observed. Typical clinical manifestation [including Visual analogue scale (VAS) score of joint pain, number of tenderness joints, number of swollen joints, time of morning stiffness], disease activity score uses 28 joint counts (DAS28) scores, the MOS item short from health survey (SF-36) total scores and serum JAK3, STAT3, interleukin (IL)-6, IL-17 and matrix metalloproteinase (MMPs) levels were compared between the two groups before and after treatment. The adverse effects of the two groups were also analyzed. Chi-square test, paired sample t test, independent sample t test and Fisher exact probability method were used for statistical analysis. Results:After 4, 8 and 12 weeks of treatment, the american college of rheumatology (ACR)20 compliance rates in the observation group were 37.5%(15/40), 62.5%(25/40) and 80.0%(32/40), respectively, which were significantly higher than those in the control group at the same period [17.5%(7/40), 37.5%(15/40), 57.5%(23/40); χ2=4.01, P=0.045; χ2=5.00, P=0.025; χ2=4.71, P=0.030]. After 8 and 12 weeks of treatment, the ACR50 compliance rates in the observation group were [35.0%(14/40) and 47.5%(19/40), respectively, which were significantly higher than those in the control group at the same period 15.0%(6/40) and 20.0%(8/40), χ2=4.27, P=0.039; χ2=6.76, P=0.009]. After treatment, the joint pain VAS score, number of tenderness joints, number of swollen joints, DAS28 scores and SF-36 total scores in the observation group were lower than those in the control group( t=5.55, P<0.001; t=9.98, P<0.001; t=11.77, P<0.001; t=4.50, P<0.001; t=5.28, P<0.001), and time of morning stiffness was shorter than that in the control group ( t=4.76, P<0.001). After treatment, The serum levels of JAK3, STAT3, IL-6, IL-17, MMP-3, MMP-9 and MMP-13 in the obser vation group were (2 354±476) pg/ml, (1.04±0.17) ng/ml, (12.4±2.8) pg/ml, (30±5) pg/mL, (65±14) μg/L, (76±12) μg/L, (11.5±1.8) μg/L, which were lower than those in control group [(2 715±584) pg/ml (1.22±0.29) ng/mL, (16.8±3.6) pg/ml, (40±7) pg/ml, (98±15) μg/L, (123±20) μg/L, (14.9±2.8) μg/L, t=3.03, P<0.05; t=3.39, P<0.05; t=6.10, P<0.05; t=7.35, P<0.05; t=10.17, P<0.05; t=12.74, P<0.05; t=6.46, P<0.05]. The adverse reaction rate of the observation group [35.0%(14/40)] had no statistically significant difference compared with that in the control group [27.5%(11/40)]( χ2=0.52, P=0.469). Conclusion:The overall effect of Tofacitinib com bined with leflunomide in the treatment of RA is satisfactory and it is a safe and effective way to improve the clinical manifestation, disease activity and quality of life of patients with RA. The effect may be related to the significant down-regulation of the expression levels of Serum JAK/STAT signaling pathway-related Proteins and MMPs.

Objective:To investigate the status and influencing factors of skin cleaning outside wound (hereinafter referred to as skin) in adult trauma patients.Methods:A multicenter cross-sectional investigation was conducted. From September 1 to 30, 2020, a total of 952 adult trauma patients who met the inclusion criteria were admitted to wound care clinics or trauma surgery wards of 13 military or local Grade Ⅲ Level A hospitals, including the General Hospital of the Eastern Theater Command of People's Liberation Army and the Army Medical Center, etc. A self-designed questionnaire on cleaning status of skin in trauma patients was released through the "questionnaire star" website to investigate basic information such as gender, age, education level, living status, and self-care ability, trauma information such as cause of injury, wound duration, trauma site, trauma depth, wound pain, wound peculiar smell, and wound cleaning solution, and skin cleaning status after injury such as whether to clean or not, cleaning method, cleaning frequency, cleaning duration in each time, or reasons for not cleaning. The patients who cleaned skin regularly after injury were included in cleaning group, and the other patients were included in no cleaning group. The basic information, trauma information, and skin cleaning status after injury of patients in 2 groups were investigated. Data were statistically analyzed with chi-square test, and binary multivariate logistic regression analysis was performed on indicators with statistically significant differences between the two groups to screen the independent influencing factors of skin cleaning in trauma patients.Results:A total of 952 questionnaires were received, and the recovery rate was 100%. Three invalid questionnaires were eliminated, and 949 valid questionnaires were obtained, with an effective rate of 99.68%. In 949 patients, there were 461 (48.6%) males and 488 (51.4%) females, aged 18-100 (50±18) years. Most patients were less than 60 years old, lived with their families, and could take care of themselves completely. Nearly half of the patients were with junior high school or below education level. The main causes of injury were sharp cutting injury and falling injury, the wound duration was 2-365 days, most of the injured parts were limbs and trunk, the wound depth was mostly full-thickness injury, and most patients had wound-related pain and no peculiar smell and used 5 g/L iodophor to clean the wound. Totally 684 (72.1%) patients cleaned their skin after injury, mainly by scrubbing with warm water, the cleaning frequency was mainly once or twice a week, and the cleaning time was mainly 10 or 15 min for each time. Totally 265 (27.9%) patients didn't clean their skin after injury, and the main causes for not cleaning were following the doctor's advice, followed by worrying about wound infection and loss of self-care ability. There were significantly statistical differences in constituent ratios of education level, self-care ability, cause of injury, wound pain, and wound peculiar smell of patients in 2 groups ( χ2=12.365, 24.519, 22.820, 9.572, 92.342, P<0.01). Education level, self-care ability, cause of injury, wound pain, and wound peculiar smell were potential influencing factors of skin cleaning in patients. Binary multivariate logistic regression analysis showed that self-care ability, wound pain, and wound peculiar smell were independent influencing factors of skin cleaning in patients (odds ratio=1.51, 0.52, 3.72, 95% confidence interval=1.08-2.12, 0.42-0.89, 2.66-5.22, P<0.05 or P<0.01). Conclusions:Self-care ability, wound pain, and wound peculiar smell are independent influencing factors of skin cleaning in adult trauma patients.

Objective To study the clinical features, diagnosis and treatment of torsion of testes in newborn. Method Neonates who were diagnosed with neonatal testicular torsion and admitted to Shenzhen Children's Hospital from March 2008 to July 2018 were studied. The clinical data such as days in age, time of onset, clinical manifestations, time of ultrasound examination, characteristics of ultrasound examination, surgery time, surgical types, postoperative conditions, pathological findings, and follow-up results were retrospectively analyzed. Result A total of 12 infants with torsion of testes were enrolled. The average onset time was 2.9 d, ranged from 1～10 d. The time of onset was within 24 h after birth in six infants. The median duration from onset to seeing a doctor was 3.5 d, ranged from 2 h to 28 d. First manifestations being reported grammer were scrotal swelling or mass, including 7 cases on the left side and 5 cases on the right side. Among them, 9 cases were associated with redness or cyanosis of the scrotum. Ultrasound was characterized by the disappearance or significant reduction of testicular parenchymal blood flow signal, and the sensitivity of ultrasound was 100％. The average time from admission to operation was (2.1±1.1) h. All the 12 infants had orchiectomy,after necrosis of unilateral testicle was confirmed. Eight of them underwent contralateral test icular fixation. The average operation time was 46 min. There was no wound bleeding or infection postoperatively, and the average hospital stay was 6.4 d. The pathological features were blurred residual contour of the seminiferous tubule (9 cases) or the disappearance of the seminiferous tubule structure (3 cases). After 3 to 24 months of follow-up, no contralateral testicular torsion or atrophy was found. Conclusion The rate of testicular necrosis in children with torsion of testes is high. The newborn with scrotal swelling should be diagnosed promptly with color Doppler ultrasound. If necessary, surgical exploration should be performed in time.
