Objective:To investigate the efficacy of Tanzhuo Decoction in the treatment of early diabetic nephropathy in patients with type 2 diabetes mellitus and its effect on cystatin C (Cys-C), C-reactive protein (CRP), urinary albumin excretion rate (UAER), and creatinine clearance rate (CCr). Methods:Eighty patients with type 2 diabetes mellitus complicated by early diabetic nephropathy who received treatment at Maanshan Hospital of Traditional Chinese Medicine from 2019 to 2021 were included in this randomized controlled study. They were divided into a control group ( n = 40) and a treatment group ( n = 40) using the random number table method. Patients in the control group received conventional therapy including blood glucose and blood pressure control, while those in the treatment group received Tangzhuo Decoction in addition to the same treatment as that given to the control group. Both groups of patients were treated for 30 days. The clinical efficacy as well as pre- and post-treatment Cys-C, CRP, UAER, and CCr were compared between the two groups. Results:The total response rate in the treatment group was 92.5% (37/40), which was significantly higher than 75.0% (30/40) in the control group ( χ2 = 4.50, P < 0.05). After treatment, Cys-C, CRP, and UAER in the treatment group were (2.04 ± 0.08) mg/L, (3.97 ± 1.71) mg/L, and (91.18 ± 18.68) μg/min, respectively, which were significantly decreased compared with those before treatment ( t = 12.14, 5.59, 4.73, all P < 0.05). After treatment, CCr in the treatment group was (56.3 ± 5.01) mL/min, which was significantly increased compared with that before treatment ( t = -8.56, P < 0.05). After treatment, Cys-C, CRP, and UAER in the control group were (2.17 ± 0.04) mg/L, (4.66 ± 1.47) mg/L, and (103.93 ± 22.62) μg/min, respectively, which were significantly decreased compared with those before treatment ( t = 4.05, 5.00, 2.24, all P < 0.05). After treatment, CCr in the control group was (45.9 ± 4.9) mL/min, which was significantly increased compared with that before treatment ( t = -3.98, P < 0.05). There were significant differences in Cys-C, UAER, and CCr between the treatment and control groups ( t = -7.42, -2.29, 7.82, all P < 0.05). Conclusion:Tanzhuo Decoction for the treatment of early diabetic nephropathy in patients with type 2 diabetes mellitus has a definite effect. It can effectively reduce levels of Cys-C and UAER, reduce inflammatory reactions, improve kidney function, and delay the progression of kidney injury.

Objective:To develop a perinatal depression screening scale for Chinese urban version and test its reliability and validity.Methods:Naturally conceived women who were≥12 weeks of gestation and had regular prenatal examinations or delivered within four weeks in Xi'an and Foshan were recruited using convenience sampling. Initial entries were created through clinical interviews and expert validation of 50 of these pregnancies. Further item screening and testing for reliability and validity using correlation analysis, critical ratio method, homogeneity test, and factor analysis were performed. The final questionnaire was formed and then used to test the subjects. Fifty women who had completed the questionnaire effectively were selected for retesting 10 to 15 days after the initial evaluation. A structural equation model was constructed using the Edinburgh Postpartum Depression Scale (EPDS) as the reference criterion to conduct the scale's exploratory and confirmatory factor analysis. The receiver operating characters curve was used to determine the cut-off point of the scale.Results:(1) 1 300 questionnaires were issued, and 1 049 valid questionnaires were received with a recovery rate of 80.7%. Among them, 601 were used for exploratory and correlation analysis, and 448 were used for confirmatory factor analysis. (2) The initial entries of the scale totaled 63. After eliminating indicators that did not meet the requirements for item analysis, the final scale consisted of 22 entries in total. The final scale consisted of six dimensions, including "abnormal mood", "loss of interest and pleasure," "sleep disorder," "self-blame and guilt," "decline in conscious thought ability," and "lack of energy". (3) The correlation coefficients between the above six dimensions and EPDS were 0.609, 0.322, 0.423, 0.522, 0.545, and 0.516, respectively. The one between the total scale and EPDS was 0.715 (all P<0.01). (4) The confirmatory factor analysis of each model and the scale showed an acceptable fit and a stable factor structure with indices Chi-square/degrees of freedom =2.504, square root of approximation error=0.058, standardized root mean square residual=0.048, comparative fit index=0.925, Tueker-Lewis index=0.911. After retaining 22 items, the Cronbach's coefficients of the six dimensions ranged from 0.708 to 0.870. (5) The test-retest reliability of the total scale, six dimensions, and 22 items were 0.936, 0.786-0.846, and 0.720-0.886, respectively. (6) The receiver operating characteristic curve of the scale was drawn with EPDS≥13 as the cut-off value, and the area under the curve (AUC) of EPDS was 0.808 (95% CI: 0.744-0.872). When the original cut-off point was 21, the Youden index was the max (0.561), with sensitivity and specificity of 0.952 and 0.609, respectively. The Kappa value was 0.691, indicating that the scale was consistent with EPDS. Conclusion:This study preliminarily established a Chinese urban version of the perinatal depression screening scale with a stable factor structure and good reliability and validity.

Objectives:This study aimed to assess the efficacy and safety of bendamustine in combination with rituximab (BR regimen) for the treatment of newly diagnosed indolent B-cell non-Hodgkin's lymphoma (B-iNHL) and elderly mantle cell lymphoma (eMCL) .Methods:From December 1, 2020 to September 10, 2022, a multi-center prospective study was conducted across ten Grade A tertiary hospitals in Shandong Province, China. The BR regimen was administered to evaluate its efficacy and safety in newly diagnosed B-iNHL and eMCL patients, and all completed at least four cycles of induction therapy.Results:The 72 enrolled patients with B-iNHL or MCL were aged 24-74 years, with a median age of 55 years. Eastern Cooperative Oncology Group (ECOG) performance status scores of 0-1 were observed in 76.4% of patients, while 23.6% had scores of 2. Disease distribution included follicular lymphoma (FL) (51.4% ), marginal zone lymphoma (MZL) (33.3% ), eMCL (11.1% ), and the unknown subtype (4.2% ). According to the Ann Arbor staging system, 16.7% and 65.3% of patients were diagnosed with stage Ⅲ and stage Ⅳ lymphomas, respectively. Following four cycles of BR induction therapy, the overall response rate was 98.6%, with a complete response (CR) rate of 83.3% and a partial response (PR) rate of 15.3%. Only one eMCL patient experienced disease progression during treatment, and only one FL patient experienced a relapse. Even when evaluated using CT alone, the CR rate was 63.9%, considering the differences between PET/CT and CT assessments. The median follow-up duration was 11 months (range: 4-22), with a PFS rate of 96.8% and an OS rate of 100.0%. The main hematologic adverse reactions included grade 3-4 leukopenia (27.8%, with febrile neutropenia observed in 8.3% of patients), grade 3-4 lymphopenia (23.6% ), grade 3-4 anemia (5.6% ), and grade 3-4 thrombocytopenia (4.2% ). The main non-hematologic adverse reactions such as fatigue, nausea/vomiting, rash, and infections occurred in less than 20.0% of patients.Conclusion:Within the scope of this clinical trial conducted in China, the BR regimen demonstrated efficacy and safety in treating newly diagnosed B-iNHL and eMCL patients.
