Objective Changes in relevant indexes in the mouse model of early-onset ovarian insufficiency caused by Tripterygium wilfordii polyglycoside were analyzed,and the optimal time point for intervention was determined.Methods Forty female ICR mice were randomly divided into control and A,B,C,and D model groups with eight mice in each group.The control group was gavaged with purified water for 14 days(0.01 mL/10 g),and the remaining groups were administered a Tripterygium wilfordii polyglycoside suspension(80 mg/kg,0.01 mL/10 g)for 1 day(A model group),3 days(B model group),7 days(C model group),or 14 days(D model group),and samples were collected.Body weight and wet weights of the uterus and bilateral ovaries of mice were determined in each group.Serum FSH,LH,E2,P,AMH,INH-B,and T contents were measured using enzyme-linked immunoassays.HE staining was used to observe the number and developmental status of follicles and corpus luteum at all levels in mice of each group.TUNEL staining was used to detect the apoptosis in the ovaries of mice in each group.IHC detected expression of VEGFA,CD34,and EPO proteins in the ovaries of mice in each group.mRNA expression of HIF-1α,SDF-1,and CXCR4 in each group of mice was detected by PCR.Results Compared with the control group,changes in indicators in model A mice did not meet the POI modeling standard.The ovarian index,uterine index,and body weight of mice in the B model group were decreased significantly(P<0.01),the weight of the C model group was decreased significantly(P<0.01),and the ovarian index of the D model group was decreased significantly(P<0.05).Serum contents of FSH and LH in B,C,and D model groups were increased(P<0.05,P<0.01),the E2,PROG,AMH,INH-B,and T contents were decreased(P<0.01).The numbers of basal follicles,pre-sinus follicles,sinusoidal follicles,antral follicles,preovulatory follicles,and corpus luteum were decreased significantly(P<0.05,P<0.01)and the number of atresia follicles was increased significantly(P<0.01)in B,C,and D model groups.The apoptotic area of TUNEL staining in A,B,C,and D model groups was increased significantly(P<0.05,P<0.01).Expression of CD34,VEGFA,and EPO in B,C,and D model groups was decreased significantly(P<0.05,P<0.01).mRNA expression of HIF-1α,SDF-1,and CXCR4 in A and B model groups was significantly increased(P<0.05,P<0.01).Compared with the B model group,the relevant indexes of C and D model groups were changed significantly,indicating that C and D models were more serious and tended to develop POF.Conclusions The B model group is the turning point of ovarian function from impaired POI to irreversible POF,suggesting that 3 days of administrating Tripterygium wilfordii polyglycoside is optimal to induce a POI disease model for effective drug intervention.

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.

OBJECTIVES:
The results of elastic imaging in evaluating the function and histopathological changes of allogeneic renal transplantation are contradictory, one of the important reasons may be that there are differences in human parameters related to kidney transplantation among individuals. The purpose of this study is to explore the related human body parameters on shear-wave elastography (SWE) effects on quantitative stiffness of graft cortex.
METHODS:
From March 2021 to November 2021, a total of 63 patients with allogeneic kidney transplantation in the Department of Ultrasonography, Third Xiangya Hospital, Central South University, were selected to collect the parameters of two-dimensional, color Doppler and SWE. The subjects were divided into a <20% group and a 20%-30% group according to the variation of cortical hardness measurement. Mann Whitney U test was used to compare the differences in relevant human parameters, and Spearman rank correlation was used to analyze the correlation between relevant human parameters and cortical hardness of transplanted kidney.
RESULTS:
There was no significant difference between the 2 groups in age, sex, postoperative time, resistance index of interlobar artery, SCr, blood uric acid, ratio of fat layer to muscle layer, and BMI (all P>0.05). Compared with the <20% group, the patients in the 20%-30% group had smaller cortical hardness of the transplanted kidney, greater total distance between the transplanted kidney and the skin surface, and thicker fat layer or muscle layer in front of the transplanted kidney (all P<0.05). The age of patients, the total distance from the transplanted kidney to the skin surface, the thickness of fat layer and muscle layer, the ratio of fat layer to muscle layer, BMI, and the variation of cortical hardness were significantly negatively correlated with the cortical hardness of the transplanted kidney (all P<0.05).
CONCLUSIONS
Human parameters relevant to kidney transplantation affect the accuracy of SWE in measuring the cortical hardness of the transplanted kidney. It is very important to obtain the highly stabile elastic measurement value and interpret the elastic measurement results according to different levels of human body related parameters in combination with individual conditions.

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database-cFos-ANAB-a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users' purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net .

Esophageal squamous-cell carcinoma (ESCC) is one of the most lethal malignancies in the world and occurs at particularly higher frequency in China. While several genome-wide association studies (GWAS) of germline variants and whole-genome or whole-exome sequencing studies of somatic mutations in ESCC have been published, there is no comprehensive database publically available for this cancer. Here, we developed the Chinese Cancer Genomic Database-Esophageal Squamous Cell Carcinoma (CCGD-ESCC) database, which contains the associations of 69,593 single nucleotide polymorphisms (SNPs) with ESCC risk in 2022 cases and 2039 controls, survival time of 1006 ESCC patients (survival GWAS) and gene expression (expression quantitative trait loci, eQTL) in 94 ESCC patients. Moreover, this database also provides the associations between 8833 somatic mutations and survival time in 675 ESCC patients. Our user-friendly database is a resource useful for biologists and oncologists not only in identifying the associations of genetic variants or somatic mutations with the development and progression of ESCC but also in studying the underlying mechanisms for tumorigenesis of the cancer. CCGD-ESCC is freely accessible at http://db.cbi.pku.edu.cn/ccgd/ESCCdb.

Objective To evaluate the effect of contrast medium on the renal function in patients with cerebrovascular disease accompanied by diabetes mellitus after receiving neuro - interventional therapy. Methods The clinical data of a total of 108 patients with cerebrovascular disease complicated by diabetes mellitus type 2, who were treated with neuro - interventional therapy during the period from March 2013 to March 2016, were retrospectively analyzed. The contrast dose used in interventional procedures was less than 250ml in each patient. The preoperative and 24 h -postoperative serum creatinine (sCr), serum cystatin C (Cys C) levels were determined, and based on the modification of dietary renal disease (MDRD) equation and Larsson equation the estimated glomerular filtration rates (eGFR) were separately calculated. Results Compared with preoperative values, the 24 h - postoperative mean sCr and Cys C levels were increased significantly (P=0. 001, P=0. 015 respectively), while the average eGFR rates were remarkably decreased (P< 0. 000 1 by using MDRD equation, and P=0. 021 by using Larsson equation). No kidney damage that needed to be treated occurred in all patients. Conclusion The contrast dose used in neuro - interventional procedures can cause decline of renal function in patients with type 2 diabetes mellitus. The combined determination of sCr and Cys C levels is helpful for the detection of contrast - induced changes in renal function as early as possible. The use of conventional dose of contrast agent in neuro - interventional procedures is safe for patients with type 2 diabetes mellitus. (J Intervent Radiol, 2018, 27:277-280)

Objective To construct and implement the gastroenterology nursing quality monitoring index, and to improve the quality of nursing in the specialty. Methods A research team was formed to analyze the major problems in nursing quality according to the top 5 diseases in gastroenterology department. The research process was based on the characteristics of gastroenterology, focusing on nursing operating skills, diseases and complications and patient safety, in the methods of literature review and brain storm. Finally, a total of 6 specialist nursing quality monitoring indicators were established: the implementation rate of digestive endoscopy preoperative preparation, the incidence of hematemesis asphyxia, the plugging rate of nasal biliary (pancreatic) drainage; the incidence of perianal skin injury in diarrhea patients; the incidence of hypoglycemia in fasting patients and the satisfaction of pain management. The key content and scientific measurement of the indicators were clarified by retrospectively analyzing and comparing 6 monitoring indicators between 2014 and 2015, 2015 and 2016 respectively. The statistical methed used was χ2test. Results In 2015, all the indicators improved except the incidence of hematemesis asphyxia than those in 2014, and the differences were statistically significant (χ2=34.710,9.223,7.834,5.547,32.899;P<0.05). In addition, all the 6 indicators improved than those in 2015, and the differences were statistically significant (χ2=102.334,5.496,4.257, 3.953,39.191,192.910;P< 0.05). Conclusions The establishment of gastroenterology nursing quality monitoring indicators, the development of targeted care measures, and the continuous improvement in the quality of specialist nursing can improve the quality of nursing management.

Objective To investigate the value of temporary balloon occlusion of the abdominal aorta in the treatment of complete placenta previa with placenta accreta. Methods From January 2015 to February 2016, 24 cases of complete placenta previa with placenta accreta were treated with temporary balloon occlusion of the abdominal aorta (the study group) before cesarean, and 24 cases of complete placenta previa with placenta accreta did not receive balloon occlusion (the control group). The operation time, intraoperative blood loss, intraoperative blood transfusion volume, the perioperative hemoglobin level, the hysterectomy rate and the related complications were compared retrospectively.Also, the hospitalization time, the blood coagulation parameters after operation, including activated partial thromboplastin time (APTT), fibrinogen (FIB), D-Dimer and reperfusion injury parameters including creatine phosphokinase (CK), creatine phosphokinase isoenzyme (CK-MB), lactate dehydrogenase (LDH) and serum creatinine were compared between the 2 groups. Results The blood loss [750 ml (400-2 000 ml) vs 2 000 ml (1 500-2 375 ml);Z=-3.214, P=0.001] and blood transfusion volume [200 ml (0-800 ml) vs 800 ml (0-1 200 ml);173, P=0.030] in the study group were lower than in the control group. The hemoglobin difference between before and after operation in the study group was lower than the control group [(12.8±13.4) g/L vs (22.9±20.1) g/L;t=-2.041, P=0.047]. In the study group, there were still bleeding in 13 cases after releasing the balloon, 5 of them received uterine artery embolization, 5 cases received uterine artery ligation, and 3 cases received uterine packing. One case had venous thrombosis in the right lower limb. Two cases (8%,2/24) in the control group had hysterectomy, while none in the study group, there was no statistical significance (P=0.489). Conclusions Temporary balloon occlusion of the abdominal aorta can effectively reduce blood loss and blood transfusion in the treatment of complete placenta previa with placenta accreta, but there is still the risk of continuing bleeding after releasing the balloon. Other methods of hemostasis might be needed.

OBJECTIVETo investigate the effect of icariin (ICA) on learning and memory abilities and cholinergic system in senescence-accelerated mice SAMP10.
METHODThe 8-month-old senescence-accelerated mice were randomly divided into the model SAMP10 group and the positive Donepezil group (1 mg x kg(-1)) and ICA groups (50, 100, 200 mg x kg(-1)), with 12 mice in each group. Another 12 8-month-old mice SAMR1 were selected as the normal control group. After 30 days of oral administration, Morris water maze, SMG-2 water maze and experimental platform were used to test the effects of ICA on learning and memory abilities of SAMP10 groups. By colorimetric determination of AChE activity in the cortex, enzyme-linked immunosorbent assay detection of ACh, ChAT, MCBC of the cerebral cortex, the effect of ICA on the cholinergic system of SAMP10 was observed.
RESULTICA could improve the abilities of space exploration and positioning navigation of SAMP10, shorten the latency in SMG-2 water maze, enhance their jumping ability in response to the passive test, and increase levels of ACh, ChAT, MCBC in the cerebral cortex of SAMP10. But its active effect on AChE in SAMP10 cortex was not obvious.
CONCLUSIONDifferent doses of icariin can improve learning and memory abilities of SAMP10 to varying degrees, which may be related to its effect on the cholinergic system.
