Chinese Journal of Biochemical Pharmaceutics 2017;37(9):425-426
Objective To investigate the clinical effect of enzyme linked immunosorbent assay (ELISA) in detecting hepatitis C antibody. Methods 200 cases of patients with hepatitis C was measured by ELISA, the gold standard method for detection of hepatitis C virus antibody, recording the test results, the data input SPSS software to give the corresponding analysis and conclusions. Results 200 cases of patients with hepatitis C were successfully completed the gold standard method and ELISA method for detection of hepatitis C virus antibody, the analysis showed that positive rate of ELISA method for detection of hepatitis C virus antibody was significantly higher than that of the gold standard method, the positive rate of ELISA was 82.50%, the positive rate of the gold standard method for was 50.00%, results suggested that HCV detection rate of ELISA method is significantly better (P<0.05). Conclusion The method of ELISA can be used for the detection of hepatitis C antibody, which has positive significance in improving the diagnostic accuracy of hepatitis C, and is beneficial to protect the efficacy and quality of life of patients.

Objective To summarize the ruptured types and surgical treatment experience for rupture of aortic sinus aneurysm. Methods Nineteen cases with aneurysm of aortic sinus were retrospectively analyzed. There were 10 cases with ventricular septal defect,6 cases with aortic valvular incompetence,6cases with other diseases,2 cases complicated by infective endocarditis. All cases underwent operational treatment. Results There were 15 cases of right aneurysm of aortic sinus,including 12 cases among them ruptured into right ventricle,3 cases rupture was penetrated into right atrium.There were 3 cases of null aneurysm of aortic sinus,including 1 case among them ruptured into right ventricle,2 cases ruptured into right atrium. There was 1 case of left aneurysm of aortic sinus, which ruptured into left ventricle. No operative death occurred in all, 1 case with aortic regurgitation light to moderate,and all cases were recovered.Conclusions The right aneurysm of aortic sinus is the most common types,and always rupture into right ventricle. It is important that aneurysm of aortic sinus should be operated as early as possible in order to avoid losing the chance of operation, particular in the patients complicated by infective endocarditis.

Differential display-PCR was used to clone the differential expressed genes between Mycobacterium tuberculosis virulence strain H37Rv and its avirulent mutant H37Ra. All of different genes were cloned, sequenced and some were analyzed by Northern-blotting. Two cDNAs that appeared to be expressed in H37Rv, but not in H37Ra, were cloned and sequenced. Rv0170, and Rv1894c, code for proteins with unknown functions. The two gene were present in H37Ra, but not expressed. These results show that mRNA DD methodology can represent a potential tool for investigation of M. tuberculosis gene expression.

Objective To assess the efficacy of the mixtures of different concentrations of ropivacaine(R) and chloroprocaine(C)for epidural anesthesia in patients undergoing hysterectomy.Methods Sixty ASAⅠorⅡpatients aged 27-56 weighing 45-75 kg undergoing elective hysterectomy were randomly divided into 4 groups(n= 15 each);groupⅠ0.75% R alone;groupⅡ0.5% R-1% C;groupⅢ0.5% R-1.5% C and groupⅣ0.75% R+1% C.The epidural catheter was placed at L_(2,3)interspace and advanced 3.5 cm into the epidural space in cephalad direction.A total of 22 ml of epidural solution was injected in each group.The onset time,block height and duration of sensory block and the onset time,degree and duration of motor block(using Bromage scale)were assessed.The use of supplementary drugs(ketamine and ephedrine)and side effects were recorded.Results The onset time of sensory and motor block was significantly shorter in groupⅡ,ⅢandⅣthan in groupⅠ(0.75% R alone).The duration of sensory and motor block was significantly shorter in groupⅡandⅢthan in groupⅠandⅣ.The incidence of hypotension was significantly increased but the incidence of discomfort produced by traction on the viscera during operation was reduced in groupⅣas compared with groupⅠ.Conclusion The anesthetic efficacy of epidural 0.5% ropivacaine is significantly enhanced when mixed with 1.0% or 1.5% chloroprocaine.

AlM: To study the trabeculectomy clinical effect of use tunnel knife to make double - deck scleral flap and to cut off the layer scleral flap of glaucoma.METHODS: Using the random grouping method to divide 46 cases (60 eyes) of glaucoma into the treatment group of 24 cases (32 eyes) and control group of 22 cases (28 eyes). The treatment group, tunnel knife was used to make double- deck sclera flap and superficial scleral flap about the size of 5mm×5. 5mm, 1/3 scleral thickness, under the sclera flap made another one about the size of 3. 5mm× 4mm, 1/3 scleral thickness, resected the middle layer of the sclera flap, removed 2mm×2mm trabecular tissue, underwent routine peripheral iridectomy, could adjust suture the superficial scleral flap, sutured Ball fascia and bulbar conjunctiva. ln control group, routine glaucoma trabeculectomy was undergone.RESULTS:Patients were followed up for 1a, the vision in treatment group was obviously better than that in the control group, with a statistically significant difference (P< 0. 05). The postoperative intraocular pressure of the two groups of patients were significantly lower than that of the preoperative one. Postoperative 1 and 3mo, no statistical significant difference of intraocular pressure in two group(P>0. 05). But after 6 and 12mo, the intraocular pressure of the treatment group were significantly lower than that of the control group, with statistically significant difference (P<0. 05). Postopeartive 1a, the cumulative complete success rate and conditions for successful rate were 90. 63% and 96. 88% in the treatment group, and those were 75% and 89. 29% in control group. There was significant difference between two groups(P<0. 05).CONCLUSlON:The trabeculectomy have a good effect to lower the intraocular pressure by use tunnel knife to make double-deck scleral flap and to cut off the layer scleral flap. The scleral flap have uniform thickness, smooth surface, and the function of the filtering bleb maintained for a long time, less postoperative complications, suitable for various types of glaucoma, so it is worthy of clinical promotion.

OBJECTIVE:To investigate the profitability of listed pharmaceutical enterprises in China,and to investigate the ba-sic profitability path. METHODS:With the help of DuPont financial analysis system,the financial data of the listed companies and other manufacturing industry during 2007-2013 were collected and compared in terms of the return on equity(ROE),profit margin (PM),asset turnover (ATO) and equity multiplier (EM),etc. RESULTS & CONCLUSIONS:During 2007-2013,average ROE and PM of listed pharmaceutical companies both were higher than those of other manufacturing industry(10.00% vs. 6.40%, 11.50% vs. 6.49%);while average ATO and EM were lower than other manufacturing industry (0.65 vs. 0.73,1.90 vs. 2.19), with statistical significance(P<0.05). It has advantages in core earnings and product profitability while disadvantage in asset turn-over and financial leverage for the listed pharmaceutical companies. Listed pharmaceutical companies’gross margin was higher (42.87% vs. 22.07%),but was offset by the higher ratio of expenses to sales(18.24% vs. 5.61%)and insufficient utilization ratio of circulating assets. To change this situation,listed pharmaceutical enterprises should focus on circulation cost saving and the im-provement of assets operation ability,especially enhancing the utilization ratio of current assets.

Objective To invstigate the diagnostic value of the detection of telomerase activity in the specimen obtained from CT guided percutaneous transthoracic needle biopsy of lung nodules.Methods The techniques of TRAP silver staining were performed to detect telomerase activity in 43 cases. Results 43 mass cases were studied includirg 32 proved to be primary lung cancer, and 11 benign lesions cytologically and clinically. Telomerase activity was detected as 28(87.5%) of 32 lung carcinomas, whereas in benign lung lesions was 1(9.1%) in 11 cases.Conclusions Detection of telomerase activity in the specimen of lung nodules by CT guided percutaneous transthoracic needle biopsy may be an effective method in the diagnosis of lung cancer and also as tumor marker.
