Methods The sorting methods of defined daily dose (DDDs) and the frequency of oral hypoglycenic drugs were used for analysis. Results The list of leading DDDs was glucosidase inhibitor, which accounted for 31.13 % of the total, followed by biguanides which accounted for 21.49%. Conclusions The glueosidase inhibitor, a new type oral hypoglycemic drugs used for lowering postprandial blood sugar level showed remarkable efficacy and safety, so it is currently the first choice for patients with diabetes.

Objective To investigate the clinical effects and safety of combination of open and laparoscopic surgery in treatment of elderly patients with gallbladder stones combined with common bile duct stones. Methods 140 elderly patients with gallbladder stones combined with common bile duct stones from May 2014 to May 2015 were randomly divided into control group (65 patients) with traditional open surgery and observation group (65 pa﹣tients) with combination surgery; then compared the perioperative clinical indicators, the total removal rate of stone, the postoperative analgesic used rate and postoperative complications incidence of the two groups. Results The oper﹣ation time, intraoperative blood loss volume, the exhaust time for first time and hospital staying time of observation group was significantly better than control group (P< 0.05). There was no significant difference in the total removal rate of stone between the two groups (P> 0.05). The postoperative analgesic used rate of observation group was sig﹣nificantly lower than control group (P< 0.05). The postoperative complications incidence of observation group was significantly lower than control group (P< 0.05). Conclusion Compared with traditional open surgery, combination surgery in treatment of elderly patients with gallbladder stones combined with common bile duct stones can efficient﹣ly shorten the operation time, speed up the recovery process, reduce the degree of trauma and postoperative pain and helpful to prevent the postoperative complications.

Methods According to the different nursing intervention mode of patients in our hospital in January January 2015 to January 2017 performed CT scanning using the Iohexol Injection group in 50 cases as control group with routine nursing intervention, the observation group used routine nursing quality nursing intervention;adverse reaction a detailed record of the two groups of patients, and the incidence of adverse reactions compared to investigate the effect of nursing intervention of adverse reactions using the Iohexol Injection CT scan. Results Routine nursing quality nursing intervention (observation group) is better than the clinical effect of CT scanning using Iohexol Injection in patients with routine nursing intervention (control group) clinical the effect and adverse reaction rates in patients with lower than the control group, the difference was statistically significant (P<0.05). Conclusion CT scan. With Iohexol Injection patients regular nursing care, high quality nursing mode intervention effect is remarkable, can effectively reduce the incidence of adverse reactions in patients, it is worthy of clinical widely used.

Objective To study the effec of nursing intervention on the quality of life in convalescent schizophrenia patients. Method 80 patients with schizophrenia were divided into observed group (n=40) and control group (n=40).The patients in observe group received nursing intervention.Patients were evaluated by Positive and Negative Symptoms Scale (PANSS) and General Quality of Life Inventory (GQOLI) at the time of beginning the trial and after half of a year of the intervention respectively. Results After the nursing intervention,the PANSS scores in observe group are significant lower than those of control group (P

Objective To investigate the difference between two substrains,5-8F and 6-10B,of nasopharyngeal carcinoma cell line SUNE1on expressing metastasis-associated gene 1 (MTA1),and evaluate the silencing effect of lentivirus-mediated RNA interference (RNAi) on MTA1 in human nasopharyngeal carcinoma cell line.Methods The differential expression of MTA1 mRNA and MTA1 protein in 5-8F and 6-10B cell lines were detected by real time PCR and Western blotting respectively.Short interference RNA (siRNA) fragment targeting MTA1 gene was designed using online databases and software.A specific RNAi lentiviral vector targeting human MTA1 gene was constructed and transfected into nasopharyngeal carcinoma cell line 5-8F.Real time PCR and Western blotting were performed to detect the expressive changes in MTA1 mRNA and MTA1 protein in the transfected 5-8F cells respectively.Results Compared with cell line 6-10B,the expressions of MTA1 mRNA and MTA1 protein were higher in 5-8F cell line.Sequence analysis validated the correct insert of siRNA targeting MTA1 gene into the lentiviral vector.Real time PCR and Western blotting results showed that the expressions of MTA1 mRNA and MTA1 protein in 5-8F cell lines were down-regulated significantly after siRNA transfection.Conclusions MTA1 may promote the malignant transformation and enhance the metastatic potential of nasopharyngeal carcinoma cell lines.The expression of MTA1 in 5-8F cells can be inhibited effectively by MTA1-specific siRNA expression lentiviral vector,which provides a valuable tool for investigating the role of MTA1 gene in the carcinogenesis and progression of nasopharyngeal carcinoma.

Objective To.investigate the accuracy and reliability of monocyte count of three methods.Methods The specimens classified by blood cell analyzer WBC monocytes ＜ 15％,15％-20％,＞ 20％ were taken randomly,draw 20 μ l after mixing,put in monocyte direct count dilution and count,and underwent routine smear,stained by Swiss-Gibbs and manual classified by microscope,and then compared the results of the three methods.Collected one copy each of the high,medium and low proportion of monocytes specimens,and counted 30 times by the three counting method.Results Blood cell analyzer in WBC monocytes 15％-20％,＞ 20％ had poor correlation with the results of the other two methods.Repeatability comparison of three methods,medium and low sample were better with method 1 and 2,high value sample was good with method 3.Conclusion The specimens of monocytes ≥ 15％,especially scatter plot is abnormal,must be confirmed by microscopic examination.

Objective To observe the effect of blood-cooling and blood-stasis-removing Decoction on anti-double-strain DNA ( anti-dsDNA) antibody, anti-nucleosome antibody ( AnuA) and serum levels of interleukin ( IL) -6, 17, 21 in spontaneous systemic lupus erythematosus ( SLE) MRL/lpr experimental rats. Methods The experimental rats were divided into blank control group, model group, and high- and low- dose Chinese medicine groups ( 25.2, 12.6 g/kg respectively) , the treatment lasting 8 weeks. At the end of the experiment, the blood taken from the orbital veins was separated for obtaining serum, and then the serum anti-dsDNA antibody, AnuA, IL-6,17,21 levels were tested by enzyme-linked immunosorbent assay ( ELISA). Results The serum autoantibody and IL-6, 17, 21 levels of rats in the model group were increased significantly as compared with the blank control group ( P<0.01). The serum antibody and cytokine levels of Chinese medicine groups were reduced as compared with the model group, the difference between high-dose Chinese medicine group and model group being significant ( P<0.01). Conclusion Blood-cooling and blood-stasis-removing Decoction has certain effect on reducing the serum levels of anti-dsDNA antibody, AnuA, and IL-6,17,21, which may coniribute to one of its therapeutic mechanisms for SLE.

Objective To investigate the pathogenesis of cerebral watershed infarction (CWI) through analyzing the appearance examined by Color duplex Imaging(CDI) and transcranial doppler (TCD).Methods One hundred and forty-two patients with CWI diagnosed by magnetic resonance imaging(MRI) were enrolled in the study group and 150 patients with acute cerebral infarction were enrolled in the control group.The results of CDI and TCD were retrospectively analyzed of the two groups.The vascular stenosis,plaque detection rate,plaque characteration,plaque scores,the cause of low blood volume,intracranial collateral circulation were compared between the two groups to investigate the pathogenesis of CWI.Results Among the 142 cases in the study group,there were 72 cases of severe stenosis and occlusion,21 cases of moderate stenosis,31 cases of mild stenosis and 18 cases without stenosis and there were 19 cases of severe stenosis and occlusion,41 cases of moderate stenosis,23 cases of mild stenosis and 67 cases without stenosis among the 150 cases in the control group.There were significant differences in the two groups (x2 =66.583,P =0.000).There were significant differences on the plaque detection rate between the two groups (80.99％ (115/142) vs 49.33％ (74/150),x2 =32.010,P =0.000).There were significant differences on the scores of plaque between the study group and the control group ((11.47 ± 3.78) points vs (6.57 ± 3.53) points,t =4.019,P =0.001).There were significant differences on the defined cause of low blood volume between the study group and the control group (54.93％ (78/142) vs 11.33％ (17/150),x2 =63.164,P =0.000).There were 50 patients had collateral circulation in the study group and 38 cases in the control group,there were no significant differences between the two groups (35.31％ (50/142) vs 25.33％ (38/150),x2 =3.381,P =0.066).Conclusion Angiostegnosis,microemboli from the unstable atherosclerosis plaque,lower perfusion on the basis of hypovolemia are all the pathogenesis of CWI.CDI combine with TCD can provide more information in vascular evaluation and treatment.
