Objective:To clone Fab genes of anti-p185 monoclonal antibody 5E12 and express it in E.coli.Methods:Fd and ? genes were cloned by RT-PCR, inserted into Fab expression vector and expressed in E.coli. The N-terminal sequences of V regions was resumed by PCR mediated mutagenesis. The antigen-binding activity of the Fab were tested by ELISA and immunohistochemistry.Results:Fd and ? genes were cloned and expressed in E.coli. But the bacterially expressed Fab fragments showed no antigen binding activity. After the N-terminal sequences of V regions was corrected to original sequences, the Fab expressed in bacterial was able to target HER2/neu-expressing cells(NIH3T3/erbB-2 cells). Correction of Fd N-terminal sequences could partially resume the antigen binding activity. But correction of ? chain N terminal sequences was shown no expected result.Conclusion:Successful in constructing and expressing anti-p185 Fab, which will benefit the construction of other engineering antibody and humanization of murine anti-p185 McAb. We also found that the V region N terminal changes introduced with PCR primers may affect antigen binding activity seriously, to which more attention should be paid during antibody engineering.

To systematically evaluate the clinical efficacy and safety of compound Danshen injection in treating hypoxic-ischemic encephalopathy (HIE) of newborns. Computer retrievals were made in PubMed, Embase, Cochrane Library, CBM, CNKI, VIP and China info (before May 2014) and relevant literature references, and manual retrievals were made for journals and conference papers, in order to collect randomized or semi-randomized controlled trials concerning compound Danshen injection in the treatment of neonatal HIE. The quality of included references was evaluated according to literatures recommended by Cochrane Handbook. RevMan 5. 3 software was applied in the statistical treatment. Finally, a total of 13 randomized controlled trials were included, covering 1,211 patients (including 639 patients in the compound Danshen injection-treated group and 572 patients in the control group). Meta-analysis results showed that the routine treatment combined with compound Danshen injection can improve the treatment efficiency of neonatal HIE [RR = 1.28; 95% CI (1.21-1.36)], reduce the mortality rate [RR = 0.42; 95% CI (0.23-0.75)] and the incidence of long-term neurological sequelae [RR = 0.48; 95% CI (0.35-0.65)], with statistical differences. No fatal side effect was observed in all of included trials. So far, limited evidences in this study proved that the application of compound Danshen injection in the treatment of neonatal HIE can enhance the clinical efficiency. However, because of the low quality of the included trials, more well-designed and large-scale multi-center randomized controlled trials shall be made in the future.

OBJECTIVETo observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).
METHODSTotally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.
RESULTSCompared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).
CONCLUSIONChinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.

Objective To investigate the effect and safety of early intervention and delayed intervention therapy on elderly patients and younger patients with non-ST segment elevation acute coronary syndrome. Methods The patients with non-ST segment elevation acute coronary syndrome were randomly divided into early intervention group (coronary angiography taken within 24 hours after grouping) and delayed intervention group ( coronary angiography taken after 36 hours after grouping). The primary endpoint was a composite endpoint of death, myocardial infarction and stroke during 180 days follow-up. Results A total of 815 patients were enrolled, including 198 elderly patients aged 75 years and above, and 617 younger patients aged below 75 years. The elderly patients had a greater incidence of the primary endpoint than that of younger patients ( P = 0. 00). The primary endpoint of early intervention group were obviously lower than that of delayed intervention group of younger patients ( P = 0. 01 ). There was no significant difference in primary endpoint incidence of early intervention group and delayed intervention group of the elderly patients (P =0. 39). Conclusions The elderly patients with non-ST segment elevation acute coronary syndrome who underwent intervention had greater incidence of death and myocardial infarction. Early intervention reduced the rate of myocardial infarction for the younger patients. There was no significant difference in primary endpoint incidence between early intervention and delayed intervention among elderly patients.
