Three hundred and ninety five patients with bronchial asthma were randomly divided into 4 groups:patients in group A received inhaled beclomethasone dipropionate(BDP)100μg and Zhichuan decoction;patients in group B were given inhaled BDP 200μg;patients in group C took Zhichuan decoction only;patients in group D were given inhaled BDP 100 μg.Methacholine airway reactivity,pulmonary ventilation function,serum acidophilia cationic protein and symptom score were determined before and after treatment.All above indicators were significantly improved in groups A and B,which suggests that Zhichuan decoction could reduce hormone dosage in control of airway chronic inflammation,reduction of airway reactivity and improvement of pulmonary ventilation function of patients with bronchial asthma.

A rapid and sensitive liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method for quantification of sitagliptin in human plasma and urine had been developed. This method was applied to the pharmacokinetics study of sitagliptin tablet after single- and multiple-dosing in Chinese population. Plasma samples were prepared by a liquid-liquid extracted method, and urine samples were diluted. Compounds were analyzed by multiple reaction monitoring (MRM) mode with a electrospray ionization (ESI) interface. Mobile phase consisted of methanol and water (85 : 15, v/v). The linear concentration range of calibration curve was 0.5-1 000 ng.mL-1. and 0.2-100 µg.mL , intra-run/between-run accuracy was 98.98%-103.69% and 97.63%-102.29%, intra-run/between-run precision was <5.51% and 4.26% for plasma and urine sample, respectively. The stability of sitagliptin stock solution was tested for 55 days at -30 °C. Sitagliptin was stable when stored under the following conditions: 24 hours in the autosampler after sample preparation; 24 hours at room temperature, after 3 freeze and thaw cycles (from -30 °C to room temperature), 40 days at -30 °C for plasma and urine samples. The absolute recovery in plasma was 71.1%, and no matrix effect was founded. This method was proved simple, specific, sensitive, rapid and suitable for pharmacokinetics study of sitagliptin in human being.

The percutaneous transhepatic portal approach is the most commonly used technique for islet transplantation, largely owing to its safety and minimally invasive characteristic. Bleeding complications after islet transplantation are rare. A case of type 1 diabetes mellitus (T1DM) was treated in Tianjin First Center Hospital, who had a massive intra-abdominal hemorrhage after percutaneous transhepatic portal vein catheterization for islet transplantation. Through the review of the overall development of the case, we aim to improve the awareness of the complications of islet transplantation, to reduce the incidence of complications after percutaneous transhepatic portal vein transplantation, and to provide experience.

Objective To explore the effect of advanced glycation end products (AGEs) on proliferation of bone marrow mesenchymal stem cells (MSCs) and related mechanism.Methods The bone marrow MSCs were isolated from male Sprague Dawley rats and cultured in vitro.The flow cytometer was used to identify the bone marrow MSCs by detecting positive labels (CD29 and CD90) and negative labels (CD34 and CD45).The advanced glycation end products-bovine serum albumin (AGE-BSA),one of the AGEs,was used in this study.The methyl thiazolyl tetrazolium (MTT) method was used to detect the effect of AGE-BSA on proliferation of the bone marrow MSCs.In MTT test,there were 3 groups:AGE-BSA group,BSA group,and control group.In AGE-BSA group,different doses of AGE-BSA (0,25,50,100 and 200 μg/ml) was used to stimulate the bone marrow MSCs for 6 h,12 h or 24 h.In BSA group,the 200 μg/ml BSA was used to stimulate the bone marrow MSCs for 6 h,12 h or 24 h.Gene chips detection was used to detect change of genes expression in bone marrow MSCs.Results The proliferation of the bone marrow MSCs could be inhibited by AGE-BSA,in a dose- and time-related manner.Compared with the BSA group,after being treated with 100 μg/ml AGE-BSA for 24 h or 200 μg/ml AGE-BSA for 12 h and 24 h,the proliferation of the bone marrow MSCs decreased obviously.The gene chips detection found that there were changes in expression of 17 genes in the bone marrow MSCs after being treated with AGE-BSA (200 μ.g/ml) for 12 h or 24 h,and the genes were same at the two time points.Among 17 genes,the expression of 12 genes increased,including four inflammatory factors (CCL3,CCL2,CCL4 and IL-1β),and 5 genes decreased.Conclusion AGE-BSA can inhibit the proliferation of bone marrow MSCs,which may be related to the onset of the diabetic osteoporosis.

Objective To investigate the expressions of ABCG2 and V-ATPase in NSCLC and their expression rates in pathological classification, TNM stages and pathological grades and the expression correlation between ABCG2 and V-ATPase. Methods Expressions of ABCG2 and V-ATPase were accessed with EnVinsion immunohistochemistry in tumor samples from 92 NSCLC patients. The corresponding data was analyzed statistically. Results Expressions of ABCG2 and V -ATPase were found both in the lung adenocarcinoma and lung squamous cell cancer, and the difference between these two kinds of tumors was significant (P =0.003,0.000). ABCG2 expression was significantly different among TNM stages of lung adenocarcinoma (P=0.004) as well as among pathological grades of lung adenocarcinoma (P =0.028) and squamous cell carcinoma (P =0.000), while no significant difference was found among TNM stages of squamous cell lung carcinoma. The level of V-ATPase expression was associated with TNM stages of lung adenocarcinoma (P =0.026) and pathological grades of lung squamous cell carcinoma (P =0.002), however, among TNM stages of lung squamous cell carcinoma and pathological grades of lung adenocarcinoma, the difference was not significant. Additionally, the significant correlation was found between expression of ABCG2 and V-ATPase in all samples, adenocarcinoma and squamous cell carcinoma (P<0.001). Conclusion The significant correlation is found between expression of ABCG2 and V-ATPase, which indicate that they may co-work to participate in the mechanism of anticancer drug resistance.

Objective:To summarize our preliminary experience of the individual transurethral en bloc resection of bladder tumor (ERBT) based on vesical imaging-reporting and data system (VI-RADS).Methods:The clinical data of 32 bladder cancer patients admitted from January 2019 to October 2019 were retrospectively analyzed, including 26 males and 6 females. Among them, there were 27, 5, 26 and 6 patients who had primary, recurrent, single or mutiple blader tumors, respectively. And the median number of bladder tumor was 1(1-3) and the mean diameter was 2(0.6-4.5)cm.The patients were aged 37 to 82 years, with a median age of 63 years. All patients underwent multi-parameter magnetic resonance imaging (mpMRI) before surgery and acquired a VI-RADS score. Among the 32 patients, there were 8, 17, 2, 5, and 0 patients in the VI-RADS score category 1, 2, 3, 4, and 5, respectively. Based on the VI-RADS score and tumor size, morphology and number provided by the mpMRI, the urologists classified the tumor types into type 1, 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b or 5, and designed the surgical protocol for each type including the resection plan, boundary and depth. There were 8, 6, 7, 4, 0, 1, 1, 3, 2 and 0 patients in each type, respectively. The tumor types were further confirmed during the operation, and the operation was completed according to the surgical plans for different tumor types.Patients received intravesical therapy of gemcitabine within 24 hours after surgery.Results:All operations were successfully completed and none was converted to the traditional transurethral resection of the bladder tumor. The operation time was 5 to 35 minutes with a median time of 15 minutes. Tumor specimens from all patients contained the muscularis propria. Among the patients with scores 1, 2, 3 and 4, there were 8, 16, 1 and 0 patients diagnosed with non-muscle invasive bladder cancer (NMIBC), respectively. All the patients with NMIBC had negative basal resection margins and 6 out 7 muscle invasive bladder cancer (MIBC) patients had negative resection margins. There were no intraoperative complications such as bladder perforation and obturator reflex. Four patients experienced obvious postoperative bladder irritation and relieved after symptomatic treatment or removing catheter. Twelve patients received second resections, including 10 NMIBC patients and 2 MIBC patients. No residual tumor was found in the re-resected specimens. There were 9 and 12 NMIBC patients received regular intravesical therapy of gemcitabine or BCG, respectively. Among the 7 MIBC patients, 5 received radical cystectomy and two received bladder-preserving treatment including second resection, adjuvant chemotherapy and radiotherapy. The follow-up period was 3-12 months, with a median of 6 months. One NMIBC patient relapsed at 9th months after surgery and underwent ERBT.Conclusions:The personalized ERBT based on VI-RADS is safe and feasible, and can achieve negative margins in all NMIBC and some MIBC without severe complications.

Objective:To investigate the potential mechanism by which Brucella suis vaccine strain S2 induces the apoptosis of BV-2 microglia cells, and to discover new protein targets for neurobrucellosis treatment. Methods:BV-2 microglia cells were treated with Brucella suis vaccine strain S2 for 0, 3, 6, 12 and 24 h. Western blot assay and RT-qPCR were performed to detect the expression of p-JNK and p53 at protein and mRNA levels in BV-2 microglia cells. Cell apoptosis was measured by flow cytometry. Immunofluorescence was used to analyze nuclear p-JNK. Results:Brucella suis vaccine strain S2 could promote the expression of p-JNK and p53 at both protein and mRNA levels and increase nuclear p-JNK in BV-2 microglia cells. Moreover, it could also induce the apoptosis of BV-2 microglia cells. Conclusions:Brucella suis vaccine strain S2 could promote the apoptosis of BV-2 microglia cells through activating JNK and promoting p53 expression.

Objective:This study aims to explore the possible development path of hospital research assistants in China based on the cognition of the demand and management status quo from research management personnel in tertiary hospitals.Methods:62 scientific research management personnel from all over the country were surveyed, data about their cognition and the current status of scientific research assistants, that including the willingness of employ, position cognition, eligibility and competence, quantity and efficiency, management implementation, influencing factors and difficulties in team development, were collected and analyzed. Regarding to the practical needs and management status, the results were described by frequency, percentage and average score, and the rank sum test was used to verify whether there was any difference in the employment intention between the management department and the project team in the cognition of the survey subjects.Results:From the perspective of scientific research managers, there is a strong willingness at hospital level to employ the research assistant, positions require applicants with bachelor′s degree or above in medicine or other related majors. The most urgent needs are management of project funds, equipment and consumables, research integrity and ethics.The interviewees who work with research assistants think that the effect of research assistants on improving scientific research efficiency is obvious.However, the percentage of formulation of research assistants management measures is less than 40%, and the percentages of uniformly organized training and assessment are relatively low. There are still problems and challenges, such as incomplete cognition of the positioning and function, incomplete functional and vocational system, imperfect incentive mechanism and insufficient support for ability cultivation and improvement.Conclusions:It′s necessary to strengthen the top-down design of the development of scientific research assistant team and the construction of career system, improve the management basis and implementation mechanism, supporting resources should be in place, and promote capacity building system in order to develop a long-term mechanism of mutual promotion between the team building of scientific research assistants and the innovation of hospital scientific research management.
