Objective To analyze the related factors of ADR/ADE cases caused by Sanqi Panax notoginseng for injection(lyophilization),in order to provide reference for clinical rational use of Sanqi Panax notoginseng for injection.Methods Adopted the method of retrospective study,this paper statistically analyzed ADR/ADE cases caused by Sanqi Panax notoginseng for injection(lyophilization)in the database of Adverse Drug Reaction Monitoring Center in Qingdao from January 2015 to December 2015.Results There were altogether 123 ADR/ADE cases caused by Sanqi Panax notoginseng for injection(lyophilization)in 2015,with 90 cases in general,12 new cases, 21 severe cases;more female patients than male patients;more middle -aged and old patients;irrational use of the drug accounting for 45.53% of the total number of the report;and there was a higher proportion of irrational drug use in grass -roots medical institutions.Conclusion Irrational drug use is an important factor leading to ADR/ADE cases caused by Sanqi Panax notoginseng for injection(lyophilization),so the injection of Sanqi Panax notoginseng (lyophilization)should be regulated in order to reduce the occurrence of ADR/ADE cases.

To develop a medication reminder based on Android platform, which can be used to set up personalized reminders quickly and record the patient' s medication time-stamp and related information. In addition, the effect of using the reminder on medication compliance was studied. 14 subjects participated in the evaluation of medica-tion compliance. The differences of dosage and medication rate between the group using and without using reminder were investigated. The dosage and medication rate were got by the pill counting. The Wilcoxon matched -pairs signed rank test showed that the dosage and the medication rate of the group using reminder were higher than that without using reminder significantly(Z= -2. 93, P =0. 003 ). The results demonstrated that the use of the re-minder can improve the medication dose and rate significantly,indicate that the reminder might be a new technical support for clinical research on medication compliance, and also might reduce the workload for medical staff and patients.

Objective To observe the incidence and transformation of pyuria and bacteriuria in different time point after TURP and supply the evidence for antibiotic application.Methods From March,2011 to May,2012,84 patients with BPH admitted in our hospital.Their ages ranged from 61 to 87 years old,mean (71.9±7.6) years.The volume of prostate in those patients ranged from 27.8 to 118 ml,mean (70.8±24.1) ml.The procedure of TURP was undergone in all of them.In one week after the operation,two urine specimens from each patient,one for urine routine examination and one for urine culture,were collected 24 h after the catheter have been withdrawn.The catheter was also cultured.During the following-up,urine routine examination and urine culture were regularly performed in 1,2,3 months after surgery.If the patient had both pyuria and bacteriuria,he should be excluded the study.Results The pyuria rate on one week,one month,two months and three months were 54.8% (46/84),100.0% (82/82),65.8% (48/ 73),34.2% (25/73),respectively.There is a significance difference among those groups (P<0.05).It seemed that the pyuria would appear in all patients.However,the incidence would gradually decrease.It seemed that the pyuria has the tendency of self-recovery.A significant difference of prostatic resection volume after 3 months could be observed in the pyuria group (31.4±15.2 ml) and non-pyuria group (24.8±11.6 ml) (P<0.05).The bacteriuria rate on one week,1,2,3 months were 7.1% (6/84),11.0% (9/82),6.8% (5/73)and 0,respectively.There is no significance difference among the groups (P>0.05).Conclusions Pyuria will appear after TURP and the incidence reduced gradually following the time.The pyuria alone without the bacteriuria may be explained by inflammation,that antibiotics were unnecessary.The bacteriuria alone without the pyuria may be considered as asymptomatic bacteriuria or bacterial colonization,antibiotics were unnecessary,either.

Proteolytic degradation has been a severe problem when Pichia pastoris is employed to express recombinant proteins.One alternative method to circumvent this problem is to construct protease gene disruptant.However,the main study of gene disruption is focused on nonrecombinant Pichia pastoris rather than recombinant strain.In our study,we established two different methods to directly disrupt PRC1 and KEX1 gene in recombinant Pichia pastoris.On the basis of this,we further discussed and compared the application and advantages of both methods.

Objective To evaluate prospectively the preoperative use of 16-multidetector computed tomography (MDCT) with cholangiography and angiography in determining the resectability of hilar cholangiocarcinoma.Methods From January 2002 to January 2009,75 consecutive patients with hilar cholangiocarcinoma underwent preoperative MDCT with cholangiography and angiography.3D images of the portal vein,hepatic artery,and bile ducts were created and viewed simultaneously.The accuracy of MDCT with cholangiography and angiography was determined by comparison with intraoperative and pathologic findings.Results All patients tolerated the CT imaging well.The sensitivity,specificity,and accuracy rates were 92.9%,100%,and 96%for portal invasion and 83.3%,100 %,and 93.3%for hepatic arterialinvasion.The accuracy rate of longitudinal tumor extension,using the Bismuth-Corlette classification system,was 96 %.The sensitivity,specificity,and accuracy of prediction of resectability were 95.7%,82.1%,and 90.7%,respectively.Conclusion Preoperative MDCT with cholangiography and angiography gave a good assessment of the degree of biliary and vascular involvement of hilar cholangiocarcinoma.It also accurately predicted resectability in patients with hilar cholangiocarcinoma.

Objective To investigate the water infectivity in key water regions,and analyze the transmission risk of schisto-somiasis in suspicious and high-risk environments in Hubei Province in 2016. Methods Schistosome-endemic areas of the Yangtze River,the Hanbei River and the Fu River were chosen as the surveillance and forecast sites. The water infectivity was detected by using the sentinel mice during the flood season. The infection status of residents in the villages around the surveil-lance sites and the activities of human beings and domestic animals were surveyed. The emergency response system was initiated when the water infectivity areas were detected. Results From May to June,among the ten surveillance sites of the first batch, two positive spots with infected mice were found,accounting for 20%. All the recovered mice(totally 200)were dissected:five mice were infected,with a total infection rate of 2.5%. Totally five schistosome adult worms were collected,with mean worm bur-den of 1 worm per infected mouse. The site with cercariae-infected water body started the emergency response and no epidemic occurred. From August to September,among the eight surveillance sites of the second batch,the recovered mice(totally 160) were dissected,and no infected sentinel mice were found. Conclusion The sentinel mice method plays an important role in an-alyzing the schistosomiasis transmission risk in Hubei Province.

AIM:To construct eukaryotic expression plasmids encoding Sox2 and Sox2 K247R and identify their expression and SUMOylation. METHODS: With gift plas-mid encoding Sox2 gene as a template, Sox2 K247R was obtained by overlapping extension PCR, followed by construction of pCMV-HA-Sox2 and pCMV-HA-Sox2 K247R. After enzyme digestion analysis and DNA sequencing, these two constructs were transfected or co-transfected with pC-MV-Myc-SUMO1 into 293 FT cells by lipofectin method. Western blot was employed to analyze expression and SUMO ylation of Sox2. RESULTS: It was revealed that eukaryotic expression vectors were constructed with correct sequence, where in mutant Sox2, the AAG codon was switched to CGG codon. Western blot results showed that good expression of both wt and mut Sox2, of which the latter could not be modified by SUMO1. CONCLUSION: Successful construction and expression of Sox2 and Sox2 K247R. Sox2 could be SUMO lyated in vitro but Sox2 K247R not.
