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 retrospectively analyze of factors influencing early preterm birth(EPB)and late preterm birth(LPB)in pregnancy women with placenta previa complicated by placenta accreta spectrum disorders(PAS),and assess maternal and infant outcomes.Methods We included 590 cases of pregnancy women with placenta previa complicated by PAS who underwent cesarean sections at five hospitals in Wuhan and Xianning cities between January 2018 and June 2021.These patients were divided into three groups based on delivery gesta-tional age:EPB,LPB,and term birth(TB).A multiple logistic regression model was employed to analyze the risk factors associated with EPB and LPB.Additionally,differences in early maternal and infant outcomes among these groups were examined.Results Among 590 pregnancy women with placenta previa complicated by PAS,the proportions of EPB and LPB were 9.7%and 54.4%.The use of uterine contraction inhibitors prior to cesarean section,vaginal bleeding,and previous cesarean sections history were identified as risk factors for both EPB and LPB.The proportion of severe postpartum hemorrhage was comparable between the EPB group and the LPB group;however,the incidence of neonatal asphyxia,low birth weight infants,and the rate of newborns transferred to the Neonatal Intensive Care Unit(NICU)within 24 hours after cesarean delivery were significantly higher in the EPB group compared to the LPB group.Conclusions Placenta previa complicated by PAS predominantly leads to LPB.The history of prior cesarean sections,uterine contractions,and vaginal bleeding prior to cesarean section,are sig-nificantly associated with both EPB and LPB.During the perinatal period,efforts should be made to extend gesta-tional weeks under close monitoring to minimize the incidence of premature births and thereby improve early mater-nal and infant outcomes.

In order to investigate the changes in lipid metabolism of the host after infection with porcine epidemic diarrhea virus(PEDV),blood,intestinal and cellular samples were collected from PEDV-infected piglets and Vero cells,and the levels of triglyceride(TG)and total cholesterol(TC)were detected by blood biochemical analyses,flow cytometry,and immunofluorescence,and changes in the gene levels of the enzymes related to lipid metabolism of the hosts were detected by qPCR.The results showed that PEDV infection significantly elevated host total lipid levels and sig-nificantly promoted the expression of enzymes related to fatty acid and cholesterol metabolism in the intestine and Vero cells of piglets.In conclusion,PEDV infection leads to an increase in host to-tal lipid levels,remodeling of lipid metabolism in piglets intestine and Vero cells,and lipid metabo-lism gene changes.The results of this study show that lipid metabolism-related genes can be used as a key target to influence PEDV replication,which will provide a new theoretical basis for the subsequent prevention,control and treatment of PEDV infection.

Objective:To explore the clinical effect of observation and psychological intervention, splint or brace fixation as well as surgical treatment on habitual dislocation of the hip (HDH) and to combine the authors' data with a compilation of the cases from the literature, evaluingating the epidemiological characteristics of HDH and the treatment scheme to maintain the stability of hip joint by systematic literature review in children.Methods:A retrospective analysis of the relevant data of 11 patients (12 hips) with HDH were treated from March 2007 to March 2021, including 2 boys and 9 girls. The age of the first dislocation was 2.25 (1.66, 3.75) years old and 4.33 (3.33, 6.17) years old at the age of diagnosis. At the same time, the relevant literature reports were searched from 1932 to 2022, and 24 HDH patients reports and clinical studies were confirmed to be included in this study according to the inclusion and exclusion criteria. The data of 33 patients (38 hips) with HDH who were obtained in the literature, including 5 boys and 28 girls. The age of the first dislocation was 2.00 (1.50, 2.00) years old and 4.00 (2.55, 5.00) years old at the age of diagnosis. A total of 44 patients (50 hips) with HDH who were analyzed, including gender, age of first dislocation, age of diagnosis, mode of stimulating dislocation, side and direction of dislocation, accompanying symptoms, family history, trauma history and imaging examination. The data of 41 patients with HDH (3 patients were excluded due to lack of treatment description) were treated with observation and psychological intervention in 19 patients, splint or brace fixation in 13 patients, and surgical treatment in 9 patients. The femoral neck-stem angle, acetabular index, central edge angle (CE angle) and Reimers instability index were measured by AutoCAD software, and the hip function was evaluated by Harris standard. Meantime, the disappearance time of dislocation was recorded.Results:The average follow-up time of 44 patients (50 hips) with HDH were 4.05±2.93 years old, and the time of disappearance of dislocation after treatment were 1.28±1.19 years old. Patients were diagnosed as 7 boys and 37 girls, 30 right and 8 left as well as 6 bilateral, the age of the first dislocation was 2.64±1.54 years old and 4.52±2.64 years old at the age of diagnosis. The data of 39 patients took hip flexion, adduction, internal rotation or hip flexion and adduction as the mode of stimulating dislocation. There were 43 patients with posterior dislocation, 41 patients with an audible "click" sound during dislocation, 36 patients with painless dislocation, and 37 patients with "vacuum phenomenon" were captured at the moment of dislocation. All patients with HDH had no specific family history and obvious history of trauma. There was no significant difference in general data between observation and psychological intervention group, splint or brace fixation group as well as surgical treatment group ( P>0.05). Harris standard to evaluate hip function, CE angle and Reimers instability index of the affected side were significantly different from those before and after treatment at the moment of dislocation ( H=127.51, P<0.001; H=55.70, P<0.001; H=54.69, P<0.001). Compared with the immediate disappearance of dislocation in the surgical treatment group, the disappearance time of dislocation in the observation and psychological intervention group and the splint or brace fixation group were significantly longer, and the difference was statistically significant ( H=20.83, P<0.001). Conclusion:Without specific family history and obvious trauma at young girls, painless posterior dislocation of hip with an audible "click" sound and "vacuum phenomenon" at the moment of dislocation are the significant epidemiological characteristics of HDH. Observation and psychological intervention, splint or brace fixation are recommended as the initial treatment scheme. When conservative treatment is ineffective, surgical treatment is needed to stabilize the hip joint quickly.

Severe traumatic brain injury (sTBI) as the most common emergency severe syndrome in neurosurgery has a high mortality and poor prognosis. Decompressive craniectomy is the first treatment choice for sTBI. The reverse question mark incision was usually adopted in decompressive craniectomy, but some scholars also suggest using the n-type incision and Kempe incision. Although the curative effect is remarkable when using the above incisions, the incidence of postoperative complications is high, such as cerebrospinal fluid leakage, poor wound healing and flap ischemic necrosis. Moreover, the advantages and disadvantages of different incisions are not clear. Therefore, some scholars proposed retroauricular incision decompressive craniectomy for sTBI patients because this incision that retains blood supply through a new flap can provide better decompression effect and reduce incision-related complications. The authors review the research progress in retroauricular incision in aspects of the methods, indications and its advantages and disadvantages in constrast with other incisions, so as to provide a theoretical basis for the selection of incision for decompressive craniectomy in sTBI patients.

Life sciences are the disciplines most closely related with human beings. As experimental disciplines, life sciences develop rapidly and highly intersect in many scientific fields. Under the "double first-class" initiative, the comprehensive development-oriented talent training system has put forward an urgent need for life sciences literacy and comprehensive ability training of college students. Taking the reform of liberal education curriculum system as an opportunity, we developed a series of eight life sciences practical liberal courses for students with non-biology majors. The courses cover all sub-disciplines or directions of life sciences, and aim to foster interdisciplinary talents with life sciences knowledge and literacy, as well as practical and innovative abilities. These courses could serve as references for experimental teaching centers in colleges and universities to set up practical liberal and experimental courses.

The incidence of acute kidney injury (AKI) in Neonatal Intensive Care Unit (NICU) is about 30%.The morbidity and mortality of AKI are higher in very premature infants, very low birth weight infants and infants with long mechanical ventilation.Serum creatinine (Scr) and urine output are diagnostic indicators for AKI, which usually change within 12-48 hours after the onset of irreversible injury, and cannot be used for early diagnosis and clinical intervention.Therefore, it is necessary to search for indicators of early renal insufficiency, aiming to intervene and prevent early-stage AKI or reduce the occurrence of AKI.Near-infrared spectroscopy (NIRS) is a non-invasive, continuous, real-time monitoring method, which serves as a supplement to conventional biochemical markers.It provides evidence of early-stage renal ischemia and hypoxia, which contributes to prevent or reduce AKI.This study reviews the clinical application of neonatal renal oxygen saturation monitoring, thus providing clinical reference for renal function protection in critically ill neonates to reduce the occurrence of AKI and improve their prognosis.

Immune checkpoint inhibitors (ICIs), including programmed death receptor-1 (PD-1)/ligand (PD-L1) and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) monoclonal antibody, have been approved for the treatment of multiple advanced malignant tumors, on account of its ideal antitumor activity. For patients receiving ICIs treatment, glucocorticoid intervention and treatment are often applied because of some complications associated with tumor, immunotherapy-related adverse reactions, and pretreatment before immunotherapy combined with chemotherapy. However, excessive physiological dose of glucocorticoid has a certain immunosuppressive effect, which may even affect the curative efficacy of ICIs. Thus, there are controversies about the use of steroids in patients receiving ICIs treatment. In this article, we reviewed the progress of steroids effect on the efficacy of ICIs.

Objective To investigate the safety and efficacy of 177Lu-prostate specific membrane antigen (PSMA)-617 in the treatment of metastatic castration-resistant prostate cancer (mCRPC).Methods From August 2017 to September 2018,11 patients(average age 70.6 years) with mCRPC who underwent 177Lu-PSMA-617 therapy in Nanjing First Hospital were studied.All patients underwent 68Ga-PSMA-11 PET/CT before therapy to assess the tumor radioactive uptake.Blood routine examination and renal function test results were documented before and after therapy to assess the safety.The efficacy was reflected by the changes of prostate specific antigen (PSA) levels and maximum standardized uptake value (SUVmax) on 68Ga-PSMA-11 PET/CT imaging.Paired t test and Wilcoxon's sign rank test were used to analyze the data.Results No acute side effects were observed after therapy of 177Lu-PSMA-617.There were no statistically significant differences after therapy in WBC counts,RBC counts,and PLT,as well as Hb levels (t values:-0.28-1.11,all P＞ 0.05).No kidney toxicity was found.The PSA level after 177Lu-PSMA-617 therapy was significantly lower than that before therapy (80.70 (14.29,1 538.00) μg/L vs 604.60 (88.41,3 980.00) μg/L;u =59,P =0.023).Of the 11 patients,only 2 had elevated PSA levels and disease progression,while the other 9 patients had varying decreases,of which 2/11 decreased by ＞30％ and 7/11 decreased by ＞50％.After therapy,SUVmax of metastatic lesions and metastatic lymph nodes were decreased in 9 and 2 patients respectively.Conclusions 177Lu-PSMA-617 has a good therapeutic value for mCRPC.It is safe and has no obvious side effects.

Objectives To systematically evaluate the effect of music given to pregnant rats on the development of brain functions in the offspring rats and to provide scientific evidence for the application of antenatal musical training and the promotion of welfare for laboratory animals.Methods We comprehensively retrieved and collected the research literatures related to the effect of music on brain function development in offsprings of the pregnant rats from Pubmed,Web of Science,Cochrane Library,Wanfang,Weipu,CNKI and CBMdisc.The retrieval time was set from the foundation date of databases to 2 April,2016.We selected literatures according to the inclusion and exclusion criteria,evaluated their utilities,then extracted and qualitatively described the data.Results Seven experimental studies were selected in this study including 4 published in Chinese and 3 in English.The object laboratory animals of those studies were Wistar or SD rats.Music materials involved comfort music,classic music,violin concerto(Liangzhu/The butterfly lovers).Intervention were given to the pregnant rats roundly from the gestation until parturition.These results showed that,to some extent,music stimulations during gestation may promote the development of brain function and improve spatial memory of the offspring rats.However,expressions of some functional receptors were not significantly altered.Conclusions Appropriate music provided to the pregnant rats promote the development of brain functions in their offspring.
