Mean platelet volume (MPV) in patients with type 2 diabetes mellitus (DM) and coronary artery disease was increased significantly.In those with acute coronary syndrome,multi-vascular disease,obesity,and highvalue of HbA1C(＞7％),the MPV was much higher.Gisini coronary score,fasting blood glucose,high density lipoprotein cholesterol and HbA1C were the independent predictors of MPV in patients with DM and coronary artery disease.

OBJECTIVEA highly sensitive and rapid high-performance liquid chromatography method with pre-column derivatization with 4-fluoro-7-nitrobenzofurazan was developed for determination of taurine in biological samples, including plasma, brain, and liver.

METHODSThe optimum derivatization reaction temperature was 70 °C, and at this temperature the reaction was complete within 3 min. The derivatized taurine was separated using phosphate buffer (0.02 mol/L, pH 6.0):acetonitrile (84:16, v/v) as the mobile phase at a flow rate of 1.0 mL/min, and a column temperature of 25 °C. The taurine derivatives were separated within 20 min (tR:14.5 min) and fluorometrically detected at 530 nm with excitation at 470 nm.

RESULTSThe intra- and the inter-day coefficients of variation for the method were 5.3% and 7.7%, respectively. The calibration curve was linear from 0.1 μmol/L to 30.0 μmol/L with a correlation coefficient of 0.9995.

CONCLUSIONThis method can be used to determine the taurine contents in plasma, brain, and liver from normal rats and human plasma.

Objective· To evaluate the safety of neoadjuvant therapy which was constituted by docetaxel based systemic chemotherapy and maximal androgen blockage for patients with locally advanced prostate cancer and to summarize the related adverse events and clinical managements.Methods· From June 2015 to February 2017,the clinical data of 55 patients undergoing neoadjuvant chemotherapy combined with complete androgen deprivation were retrospectively reviewed.The patients were given docetaxel and prednisone as DP regimen every 3 weeks and LHRH analogues with bicalutamide as maximal androgen deprivation for a total of 4 cycles.All treatment-related adverse events were observed and then recorded.Results· Two cases with liver function impairment after 2 cycles of treatment were withdrawn from the study.No severe allergic reactions occurred during neoadjuvant therapy.The most common adverse events were hematologic toxicity,while 23.6％ of patients had grade Ⅲ-Ⅳ neutropenia,and about 12.7％ had anemia.Due to a relatively short course of treatment,the skin or mucous damage,peripheral neurotoxicity and fluid retention were rare.However,hot flash,male breast development as well as erectile dysfunction were very frequently observed due to maximal androgen deprivation.The majority of these adverse events were relieved by symptomatic and supportive treatment.Conclusion · After strict selection,4 cycles of neoadjuvant chemotherapy combined with total androgen blockade could be well tolerated by the patients with high-risk locally advanced prostate cancer.Even though the adverse events were controllable,they still need to be closely monitored during treatment in order to reduce the incidence.In addition,the very low testosterone level associated endocrinal metabolic disorders caused by complete androgen deprivation were also of great concern.

Methods A retrospective analysis of consecutive 54 elderly patients undergoing hepatectomy for hepatocellular carcinoma from Jan 1995 to Dec 2002 was performed. The data were analyzed by Kaplan-Meier method and Cox regression. Results Univariate analysis and Cox regression showed Child Pugh grading, vessel invasion, satellite nodule formation, Edmondson Steiner grading, intrahepatic recurrence and distant metastasis all related to postoperative overall survival or disease-free survival of the elderly with hepatocellular carcinoma (all P

OBJECTIVETo study the mechanism of Tongjiang granule on treating GERD.

METHODThe rats in the model group received steel wire ring-cardiamyopexy. A steel wire ring was fixed firmly on cardia. The rats in the control group underwent the cardia-plasty plus pylori ligation plus stomach-empty intestine Roux-en-Y anastomosis. The rats were divided into six groups after operations at random, which were fed up respectively with Tongjiang granule of different dosage and perpulsid. No treatment groups were taken as control.

RESULTThe experiment showed that Tongjiang granule could lighten or cure RE in the pathology, decrease the hydrochloric acid in gastric juice, in the meantime, increase the motilin in the animal blood. This study indicated that the effect of Tongjiang granule group from experimental research was better than that of the control group (perpulsid).

CONCLUSIONThe effects of Tongjiang granule on treating GERD can be achieved by decreasing the hydrochloric acid in gastric juice, increasing the motilin in blood and promoting the gastric impetus in the animal experiment.

OBJECTIVETo compare therapeutic effects of electroacupuncture at Houxi (SI 3) and medicine on acute lumbar sprain.

METHODSThree hundred cases of acute lumbar sprain were randomly divided into two groups, a electroacupuncture (EA) group and a medication group, 150 cases in each group. The EA group were treated with EA at Houxi (SI 3), once each day, 3 sessions constituting one course, and the medication group with Mobike, once daily, 7. 5 mg each time. Their therapeutic effects were evaluated after treatment for 7 days and one month respectively.

RESULTSFor the short-term therapeutic effect, the effective rate was 97. 3% in the EA group and 89. 2% in the medication group with a very significant difference between the two groups (P<0. 01); for the long-term therapeutic effect, the effective rate was 99. 3% in the EA group and 93. 2% in the medication group with a very significant difference between the two groups (P<0. 01).

CONCLUSIONBoth the short-term and the long-term therapeutic effects of EA at Houxi (SI 3) on acute lumbar sprain are better than those in the medication group.

Objective:Based on the perspective of supply and demand balance, to analyze the implementation effects of primary-feature medical services measures in medical alliances.Methods:From July to September 2019, two regions with different levels of economic development were chosen, and from each region one leading hospital and two community health service centers/township hospitals were selected from its medical alliance. A total of 213 medical staff and 703 residents were surveyed, to learn their awareness and performance appraisal of these feature services.Frequency and proportion were calculated in a descriptive statistical analysis. The scores of the performance appraisal of both supply and demand sides were tested by independent sample t. Results:In the performance appraisal of such measures, the average scoring by medical staff was 4.39±0.07, and that by residents was 3.85±0.06; the residents were more concerned with service capabilities and contents, while medical staff were more concerned with service content and delivery mode; supply and demand sides were found with consensus in terms of improving the medical service quality of chronic diseases in primary level and service accessibility.Conclusions:The county-level medical alliances should focus on enhancing their capacity of primary medical services, and improving their primary service mode with the help of medical insurance institutions. Meanwhile, it is imperative to optimize the primary medical service policy in view of supply and demand balance.

Silicosis is a diffuse pulmonary fibrosis disease caused by occupational exposure to silica, which is one of the occupational diseases with high incidence in developing countries. Up to now, there is no definite drug to relieve or reverse the lung injury caused by silicosis, so it is very important to prevent, diagnose and treat pulmonary fibrosis as soon as possible. Studies have shown that a chronic inflammatory environment contributes to pulmonary fibrosis to a certain extent. Interleukin-1β is a cytokine that increases the number of inflammatory factors in the microenvironment in the immune response and plays a key role in inflammatory reaction. Therefore, the release of interleukin-1β is of great significance in the pathogenesis of silicosis. This paper aims to systematically expound the development course of silicosis, the signal pathway of interleukin-1β production, and the relationship between them.

OBJECTIVETo observe the effect of glucagon-like peptide-1 (GLP-1) on hypoxia-reoxygenation (H/R) induced injury in neonatal rat cardiomyocytes.

METHODSCultured neonatal rat cardiomyocytes were randomly divided into seven groups: normal control group, H/R group, GLP-1 + H/R group, GLP-1 + H/R + UO126 group, GLP-1 + H/R + LY294002 group, H/R + UO126 group, H/R + LY294002 group. LDH activity, apoptosis rate of cardiomyocytes, Caspase-3 activity were detected.

RESULTSCompared with normal control group, the activity of LDH, cardiomyocyte apoptosis rate, Caspase-3 activity were all significantly increased in H/R group (all P < 0.01). However, compared with H/R group, these changes were significantly attenuated in GLP-1 + H/R group [the activity of LDH (128.47 +/- 7.96) U/L vs. (223.96 +/- 22.10) U/L, P < 0.01, and cardiomyocyte apoptosis rate (2.84 +/- 2.56)% vs. (12.58 +/- 6.69)%, P < 0.01, and Caspase-3 activity (36,809 +/- 4750) RLU vs. (57,602 +/- 9161) RLU, P < 0.01], while LY294002 (PI3K inhibitor) and UO126 (MAPK inhibitor) could block the effects of GLP-1 in cardiomyocytes underwent H/R injury.

CONCLUSIONSGLP-1 could protect H/R injury mainly by inhibiting cardiomyocytes apoptosis via activating PI3K/Akt and MAPK signaling pathway.
