Objective:To assess the safety and efficacy of thiotepa, busulfan, and etoposide (TBE) conditioning followed by autologous hematopoietic stem-cell transplantation (TBE auto-HSCT) in primary central nervous system lymphoma (PCNSL) patients.Methods:Clinical data from 27 PCNSL patients who received TBE auto-HSCT at the Fifth Medical Center of PLA General Hospital between November 1, 2021, and April 30, 2024, were retrospectively analyzed.Results:Twenty-seven patients [16 males, 11 females; median age 57 (23–72) years] were included, with 12 (44.4%, 12/27) over 60. Twenty-five had newly diagnosed PCNSL and 2 were relapsed. Median time from diagnosis to transplantation was 6.9 (5.0–10.0) months. TBE auto-HSCT increased complete remission (CR) rate from 63.0 to 96.3% ( P= 0.005), and 9 of 10 patients in partial remission achieving CR post-transplant. Median follow-up was 24.5 months (range 2.0–36.0). Two-year progress-free and OS rates were (87.2±6.9) % and (88.6±6.2) %, respectively. Common grade 3 nonhematologic adverse events were diarrhea (18.5%, 5/27) and bacterial infections (14.8%, 4/27). One patient (64 years old) died from carbapenem-resistant Enterobacteriaceae infection within 2 months post-transplant, yielding a 100-day treatment-related mortality of 3.7% (1/27) . Conclusion:TBE-conditioned high-dose chemotherapy with auto-HSCT is effective, safe, and well-tolerated in PCNSL patients, including the elderly.

Objective To compare paired boxed gene 1(PAX1)methylation and p16/Ki-67 double staining alone and in combination in thinprep cytologic test(TCT)for distinguishing atypical squamous cells of undetermined significance(ASC-US)and low-grade squamous intraepithelial lesion(LSIL)population.Methods A total of 247 patients with TCT results of ASC-US and LSIL admitted in our hospital from January 2021 to December 2022 were enrolled in this study.Detection efficacy of PAX1 methylation and p16/Ki-67 double staining alone and in combination was evaluated with colposcopic pathologic results as the gold standard and the sensitivity,specificity,accuracy and area under the curve(AUC)as evaluation indexes.Results The positive rates of PAX1 methylation and p16/Ki-67 double staining were increased with the severity of pathological findings.Combined detection of PAX1 methylation and p16/Ki-67 assay had a sensitivity of 91.25％,specificity of 97.72％and accuracy of 95.51％in the women with TCT of ASC-US,and these values were statistically better than those of PAX1 methylation and p16/Ki-67 double staining alone(P＜0.01).Conclusion The combination of PAX1 methylation and p16/Ki-67 double-staining assay can further improve the diagnostic efficacy in patients with ASC-US on TCT results.

Objective To study the mechanism of single Chinese medicine and compound in the treatment for sequelae of pelvic inflammatory disease.Methods We searched Pubmed,Web of Science,CNKI,Wanfang and other databases,to find out relevant literature on the treatment of SPID and their mechanism of herbal medicine since the etablishment of the database to March 2023,and summarized the literatures.Results A total of 428 literatures were included,from the included literature,we screened reports on the mechanism of of single Chinese medicine and compound in the treatment of pelvic inflammatory disease,including regulating the secretion level of cytokines and inflammatory mediators,promoting the apoptosis of inflammatory cells,inhibiting lipid peroxidation,inhibiting tissue fiber,improving blood circulation,regulating metabolic pathways and cell signal transduction,and regulating immunity etc.Conclusion To conduct in-depth research on the mechanism of action of traditional Chinese medicine in the treatment of sequelae of pelvic inflammatory disease and to provide reference for the development of new drugs of SPID.

To investigate a new teaching model so as to improve the teaching and learning efficiency of pharmaceutical analysis, a total of 61 undergraduates who majored in chemistry (pharmacy) were chosen as the trainees. The teaching reform based on Aalborg PBL model was conducted from such three aspects as teaching contents, teaching manners and assessment methods. Under the new teaching model, students' learning interest could be improved significantly, and their knowledge understanding, mastery and application were enhanced. Besides, the students' abilities of team work and communication were also cultivated.

Objective To investigate the influence factors of serum Angptl 2 levels is to explore the relationship between serum Angptl 2 and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM). Methods 114 cases of T2DM in clinic were selected.According to the results of color doppler ultrasonography,the patients were divided into T2DM with CAS group(T2DM + CAS,n=58)and simple T2DM group(n= 56).56 healthy subjects were selected as normal control (NC)group during the same period.ELISA method was used to detect the level of serum Angptl 2. Results Serum Angptl 2 levels were significantly higher in T2DM + CAS group and T2DM group than in NC group [(69.83 ± 12.07) vs (42.93 ± 10.44)vs (24.26 ± 8.78)ng/ml,P< 0.01].Correlation analysis showed that serum Angptl 2 was positively correlated with age,BMI,SBP,DBP,TC,TG,LDL-C,FPG and HbA1c in T2DM patients (r=0.574,0.325,0.528,0.308,0.396,0.387,0.295,0.536 and 0.601,respectively,P<0.01),and negatively correlated with HDL-C and FIns in T2DM patients (r= -0.248,-0.352,P<0.01).Similarly,multiple regression analysis showed that FIns,and HbA1c were the independent factors of serum Angptl 2 (β= -2.186,2.680,P<0.01). Conclusion Serum Angptl 2 level is closely related to obesity,blood pressure,blood glucose,blood lipid and insulin.Serum Angptl 2 may play an important role in the development of T2DM and carotid atherosclerosis.

Background:Functional dyspepsia (FD)with anxiety and gastric hypersensitivity is still one of the therapeutic difficulties in clinic. Gastrodin (Gas)may have dual effects of modulating gastric sensitivity and anxiety. Aims:To investigate the effect of Gas on gastric sensitivity and anxiety-like behavior in FD with anxiety-like gastric hypersensitivity in rats. Methods:Forty rats were randomly divided into control group,model group,buspirone group,low-dose Gas group and high-dose Gas group. Maternal separation,acute gastric irritation and restraint stress were sequentially performed to induce FD model with anxiety-like gastric hypersensitivity. At the 8th week,rats in control group and model group were intraperitoneally injected with 0. 9% NaCl solution 2. 0 mL/ kg,rats in buspirone group were given buspirone 3. 125 mg/kg,and rats in low- and high-dose Gas groups were given 62. 5,125. 0 mg/ kg Gas,respectively. The course was 7 days. Then elevated plus maze (EPM),open field test,abdominal withdrawal reflex (AWR)and electromyography (EMG) were performed. Results:Compared with control group,EPM test showed that proportions of open arms entries and duration were significantly decreased (P < 0. 01);open field test showed that virtual central grids duration (P < 0. 05),number of virtual grids climbed and times of lifting were significantly decreased (P < 0. 01);when gastric balloon dilatation pressure was equal or greater than 40 mm Hg,AWR score,area under ROC curve (AUC)of EMG was significantly increased in model group (P < 0. 05). Compared with model group,above-mentioned indices in low- and high-dose Gas groups were significantly ameliorated (P < 0. 05). Conclusions:Gas could influence the gastric sensitivity and anxiety-like behavior of the brain-stomach axis regulated anxiety-like gastric hypersensitivity in FD rat model.

Objective To investigate the effect and mechanism of DADS in inhibiting the proliferation and inducing apoptosis of gastro-esophageal cancer cells in vitro.Methods The gastro-esophageal adenocarcinoma cells OE1 9 were treated by DADS of different concentrations in vitro.Morphologic changes were observed by the microscope and MTT assay was performed to test the growth-inhibitory effect of DADS on OE1 9 cells.Apoptosis rate of OE1 9 treated with different concentrations of DADS was measured by flow cytometry.Real-time PCR was used to detect DADS-induced effects on mRNA expressions of Caspase-3 ,Caspase-9 ,Bcl-2 ,Bax and NF-κB in OE1 9 cells.Results DADS inhibited the proliferation of OE19 cells in a dose-dependent manner.The apoptosis rate of OE19 cells was 14.0%,25.4% and 19.0% and 27.2%,respectively,when treated with 40 and 80μg/mL DADS for 24 h and 48 h.Real-time PCR assay showed that DADS could enhance mRNA expression levels of Caspase-3 and Caspase-9 and significantly decrease the mRNA expression levels of NF-κB and Bcl-2 and the ratio of Bcl-2/Bax. Conclusion DADS can significantly inhibit the proliferation and induce the apoptosis of gastro-esophageal adenocarcinoma cells via mitochondria-dependent pathways,which may be related to NF-κB and Bcl-2 families.
