Objective To investigate the effect of matrix metalloproteinas-9 (MMP-9) and high sensitive C-reactive protein (hs-CRP) in type 2 diabetes mellitus (T2DM) combined with coronary heart disease(CHD). Methods Thirty-one patients with T2DM combined with CHD(T2DM combined with CHD group) ,50 patients with CHD (CHD group) and 30 healthy volunteers (control group) were studied. Serum MMP-9 was measured by ELISA, and serum hs-CRP was measured by scattering immunoturbidimetric assay. Results The level of MMP-9 in T2DM combined with CHD group (409.62 μg/L) was significantly higher than that in CHD group (263.40 μg/L) and control group [(196.15 ±44.89) μg/L] (P < 0.05).The level of hs-CRP in T2DM combined with CHD group (17.20 mg/L) was significantly higher than that in CHD group (4.57 mg/L) and control group [(1.52±0.78) mg/L] (P <0.01). MMP-9 wa significantly related with hs-CRP in T2DM combined with C HD group (r = 0.482,P < 0.01). Conclusion The serum M MP-9 and hs-CRP levels are closely associated with the occurrence and development of diabetes related coronary atherosclerosis.

Objective To evaluate the gastroesophageal reflux symptom in patients who underwent continuous ambulatory peritoneal dialysis (CAPD) and the efficacy of proton pump inhibitor (PPI) in treating gastroesophageal reflux. Methods Fifty-eight CAPD patients with good clinical and complete dialyzed eondition,who was admitted to the hospital between Jan. 2008 and July 2008, were inquired about their gastroesophageal reflux symptoms using reflux disease questionnaire (RDQ). The patients who had RDQ≥6 and <12 were received esomeprazole 20 mg daily, while those with RDQ≥12 were received esomeparzole 20 mg twice daily. RDQ score was reevaluated 4 weeks after treatment.Results The common symptom was regurgitation (64.70%), followed by acid reflux (52.9 %), non-cardic chest pain (47.1. %) and heart burn (17. 6%). After 4-week treatment, the RDQ was significantly decreased (P< 0. 05). But there was no difference in outcome of treatment between patients with RDQ≥ 12 and RDQ< 12 (P=0. 059). Conclusion The gastroesophageal reflux symptom in CAPD patients can be relieved by PPI administration, but a larger clinical trial is needed to evaluate the course and efficacy of treatment.

Objective To set up the methods of establishing rat primary benign prostatic hyperplasic glandular epithelial cell line.Methods Male spontaneously hypertensive rats were raised to 29 weeks,and then evaluated the situation of BPH with HE staining.The prostate tissue from ventral prostate lobe was aseptically removed,dissected,minced,and then dissociated in collagenase type Ⅰ.Isolated cells were collected,seeded in WAJC-404 and PrEGM medium separately,then cultured and passaged.Specificity of primitive cultured prostatic epithelial cells was identified by cell immunochemistry with CK8/18,and the cell growth curves were drawn.Then the situation of growth of the two prostatic hyperplasic glandular epithelial cell lines were analysed and compared.Results The prostatic hyperplasic glandular epithelial cell lines of the spontaneously hypertensive rats in WAJC-404 and PrEGM medium were successfully primarily cultured,purified and passaged in vitro.Cell immunochemistry proved that the cell lines specifically express cytokeratin 8/18.Cell growth curve showed that prostatic epithelial cells in PrEGM,compared with prostatic epithelial cells in WAJC-404,possessed better cell morphology,more exuberant cell vitality,faster growth rate to enter the logarithmic growth period(4 d vs.7 d)and higher peak of cell growth curve(15.3× 104/ml vs.12.8×104/ml).Conclusions Rat primary benign prostatic hyperplasic glandular epithelial cell line can be established conventionally in vitro.PrEGM medium is more suitable for primary culture of the rat benign prostatic hyperplasic glandular epithelial cell line than WAJC-404 medium.

The control group was treated with irbesartan and atorvastatin, and the observation group was treated with Shengxian decoction on the basis of the treatment. After the treatment, the TCM efficacy , related blood lipids and improvement of blood pressure variability of the two groups were compared.Results:The total effective rate of TCM syndrome in the observation group (92.5%) was significantly higher than that in the control group (70.0%), with statistically significant difference ( P<0.05); compared with before treatment, the systolic blood pressure (SBP) in both groups was significantly decreased ( P<0.05), but there was no significant difference in diastolic blood pressure (DBP) between the two groups before and after treatment ( P>0.05); there was no significant difference in SBP and DBP between the two groups after treatment ( P<0.05). Compared with that before treatment, 24 h standard deviation of systolic blood pressure (24 h SSD), day standard deviation of systolic blood pressure (dSSD) and night standard deviation of systolic blood pressure (nSSD) in the two groups were significantly decreased ( P<0.05), while there was no significant difference in 24 h standard deviation of diastolic blood pressure (24 h DSD), day standard deviation of diastolic blood pressure (dDSD) and night standard deviation of diastolic blood pressure (nDSD) between the two groups ( P>0.05). Compared with the control group, the levels of 24 h SSD, dSSD and nSSD in the observation group were significantly lower ( P<0.05), while there was no significant difference in 24 h DSD, dDSD, nDSD between the two groups ( P>0.05); after treatment, the levels of total cholesterol (TC), triglyceride (TG) and low-density lipoprotein (LDL) in the two groups were significantly decreased ( P<0.05), and the observation group was significantly lower than the control group ( P<0.05). Conclusions:Shengxian decoction is effective in treating blood stasis type hypertension, which can effectively improve blood pressure variability and blood lipid levels.

Objective To explore the relation between neurologic function recovery and neurogenesis in subventricular zone (SVZ) and perinfarct area after bone marrow stromal cells (BMSCs) transplantation in stroke rats.Methods BMSCs were harvested from rats by density gradient centfifugation and adherent culture methods,and identified by flow cytometry.Middle cerebral artery occlusion (MCAO) rat models were established by electric coagulation method.They were randomly devided into control group and transplantation group (n=12).The rats in the transplantation group were injected by tail vein with BMSCs (5×106 cells/μL) labeled with Hoechst 33342.Rats in the control group were injected with 1 mL of serum free DMEM/F12.The functional recovery of rats in two groups was evaluated by using beam walking test before transplanation and 1 week and 2 weeks after BMSCs transplanation.The survival and distributions of transplated BMSCs in the subventricular zone (SVZ) and in peri-infarct area were observed by fluorescence microscope.Ki67 expression in SVZ and peri-infarct area was determined by immunohistochemisty.Results Scores of beam walking test in transplantation group (median are 5 and 7 one and two weeks after transplantations,respectively) were significantly higher than thoses in control group (median are 3 and 5,respectively,P＜0.05).One week and two weeks after transplantations,Hoechst positive cells were found in the peri-infarct area of rats in transplantation group (7.78±1.19 cell/field and 8.15±0.90 cell/field,respectively); the number of Ki-67 positive cells in the peri-infarct area and SVZ of rats in transplantation group (15.01.19±1.58 cell/field and 13.26±1.10cell/field; 42.57±3.1 1 cell/field and 39.70±1.87 cell/field) was significantly increased as compared with those in the control group (6.29±0.83 cell/field and 6.21±0.75 cell/field; 23.22± 1.08 cell/field and 21.82±1.78 cell/field,P＜0.05).Conclusions Neurogenesis in SVZ and perinfarct region of after bone marrow stromal cell transplantation infarct rats is closely related with the motor functional recovery of infarct rats.

Objective:To assess the efficacy and safety of cinepazide maleate injection in the treatment of patients with acute ischemic stroke.Methods:A multicenter, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial, led by Peking Union Medical College Hospital, was conducted in 65 Hospitals in China. The efficacy of cinepazide maleate injection in patients with acute anterior circulation cerebral infarction with onset time of ≤48 hours, 7≤National Institute of Health stroke scale (NIHSS) score ≤25 was assessed from August 2016 to February 2019, using the proportion of modified Rankin scale (mRS) score≤1 and Barthel index (BI) score≤95 on day 14 as efficacy endpoint. The patients were divided into treatment group who were treated with cinepazide maleate injection and control group who were treated with placebo.Results:A total 937 patients were involved in the final efficacy analysis (466 in treatment group and 471 in control group). The proportion of subjects with mRS score≤1 on day 14 after treatment were higher in the treatment group than that in the control group (102/466(21.89%) vs76/471(16.14%)). Logistic regression analysis showed that patients treated with cinepazide maleate were significantly more likely to have a favorable outcome (mRS score≤1) than patients treated with placebo on day 14 ( OR=0.677, 95% CI 0.484-0.948 , P=0.023), and patients treated with cinepazide maleate were more likely to reach independence in activities of daily living (Barthel Index ≥95) than those treated with placebo on day 14 (125/466(26.82%) vs 91/471(19.32%); OR=0.632, 95% CI0.459-0.869, P=0.005). The rate of adverse events was similar between the treatment and control groups. Conclusion:The 14-day treatment with cinepazide maleate injection could reduce the degree of disability whereas did not increase the risk of adverse events.

Objective:To investigate the predictive role of dynamic changes of plasma biomarkers in patients with viral and mycoplasma community-acquired pneumonia (CAP).Methods:From January 2020 to June 2020, 141 patients with viral and mycoplasma CAP in People's Hospital of Ningxia Hui Autonomous Region were enrolled. Pneumonia severity index (PSI) scores [grade Ⅰ-Ⅱ(PSI score ≤ 70), grade Ⅲ (PSI score 71-90) and grade Ⅳ-Ⅴ(PSI score ≥ 91)], serum amyloid A (SAA), hypersensitive C-reactive protein (hs-CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR) and white blood cell (WBC) on the 1 day after admission were compared between the different pathogens (viral and mycoplasma) or different disease severity. The change in level of SAA, hs-CRP on the third day (Δ 3 d = 1 d-3 d) were compared among different disease outcome groups (patients were divided into improved group, stable group and exacerbation group based on PSI scores or lung CT images on the third day). The change in the level of SAA, hs-CRP on the seventh day (Δ 7 d = 1 d-7 d) were compared among different disease prognosis groups (patients were divided into survival group and death group based on 28-day survival data). The receiver operating characteristic curve (ROC) were drawn to evaluate the value of SAA in the evaluation of disease and prediction prognosis. Results:The level of SAA in mycoplasma group (43 cases) was significantly higher than that in virus group (98 cases) on the 1 day after admission. There were no significant differences in other plasma biomarkers between the two groups. The more severe the illness, the higher the SAA level on the 1 day after admission. The trends of other plasma biomarkers in the two groups were consistent with SAA. The levels of SAA in the patients with exacerbation of the virus group and mycoplasma group (12 cases, 9 cases) were significantly higher than those of the improved group (57 cases, 26 cases) and the stable group (29 cases, 8 cases). SAA increased gradually in the exacerbation group, decreased gradually in the improved group, and slightly increased in the stable group. ΔSAA 3 d were differences among three groups. The change trend of hs-CPR was consistent with SAA. The level of SAA in the death group was higher than that in the survival group on the seventh day. SAA increased in the death group and decreased in survival group with time from hospital admission. There were differences according to ΔSAA 7 d between death group and survival group. The change trend of hs-CPR was consistent with SAA. ROC curve showed that the value of SAA was better than hs-CRP in assessing the severity of patients on admission day, and the area under ROC curve (AUC) was respectively 0.777 [95% confidence interval (95% CI) was 0.669-0.886], 0.729 (95% CI was 0.628-0.830). The value of ΔSAA 3 d was better than SAA on the third day predicting disease trends, and AUC was respectively 0.979 (95% CI was 0.921-1.000), 0.850 (95% CI was 0.660-1.000). hs-CRP on the third day and Δhs-CRP 3 d had no predictive value. Both SAA on the seventh day and ΔSAA 7 d have predictive value for prognosis. AUC was respectively 0.954 (95% CI was 0.898-0.993) and 0.890 (95% CI was 0.689-1.000). SAA on the seventh day and ΔSAA 7 d were better than hs-CRP on the seventh day. Δhs-CRP 7 d have no predictive value. Conclusions:SAA is a sensitive and valuable indicator for CAP patients with viruses and mycoplasma. Dynamic monitoring of SAA can evaluate the patient's progression, prognosis, and assist diagnosis and treatment.

Objective: To investigate the effect of different turnover intervals in preventing stress injury to patients in emergency room. Methods: The 200 eligible patients from July 2016 to July 2017 were divided into 4 groups by random number table method, 50 patients per group, named as the conventional group, test group 1, test group 2 and test group 3. Turning frequency was used for 2.0 h in the conventional group, and 2.5 h, 3.0 h and 3.5 h in the first, second and third groups, respectively. The average body pressure of the shoulder blade, left and right lateral ankle and sacral tail between the four groups at different turning time, the incidence of stress injuries, the comprehensive satisfaction of patients with turn-over nursing were compared. Results: There was no statistically significant difference in the body pressure value of the main compression site between the four groups (P>0.05), and the incidence of stress injury was 2.0% (1/50), 2.0% (1/50), 2.0% (1/50), and 4.0% (2/50), respectively (P>0.05). The comprehensive satisfaction degree of the patients in the four groups was 71.0%(71/100), 75.0%(81/108), 79.8% (83/104), and 86.6% (97/112), respectively, with statistically significant differences (χ²=8.517, P< 0.05). For each of the two groups, only the general group and the experimental group showed statistically significant differences in the comprehensive satisfaction degree of the patients in the three groups (χ²=7.824, P< 0.01). Conclusions It shows that the 3.5 h turning-over interval can effectively prevent stress injuries, improve patient satisfaction, and reduce the workload of nursing staff without affecting patient treatment, nursing, and stress injury prevention.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.
