Objective: To investigate the effect of recombinant BCG secreting IL-2 (rBCG-IL-2) on peritoneal macrophages of mouse and inquire into the effect of rBCG-IL-2 on immunity of host. Methods: Gene engineering technology, electricity transfer- ence and inoculation tumor cell are adopted; MTT assay is used to determine tumoricidal effect of macrophages. Results: Tumo- ricidal effect of macrophages of rBCG-IL-2 groups was higher than those of the control coups and BCG groups, and the tumorici- dal effect of macrophages could reach a high state in a week. Conclusion: rBCG-IL-2 can raise tumoricidal effect of macrophages, improve immunity of host and is a prospect biological preparation.

Objective:To explore the clinical effect of hyperbaric oxygen plus magnetic stimulation and Xingnaojing injection on the coma patients with severe brain injury.Methods:120 coma patients with severe brain injury who were treated in our hospital from September 2011 to March,2016 were enrolled in the present study.According to different therapies,they were divided into the observation group (55 cases) and control group (65 cases).Both groups received conventional therapy and Xingnaojing injection,on the the basis of which,the control group received the Hyperbaric Oxygen therapy,while the observation group received Magnetic Stimulation on the basis of control group.The GCS,level of inflammatory factors,clinical prognosis as well as memory function were compared between the two groups.Results:After the therapy,the GCS score of both groups were obviously increased and that of observation group was significantly higher than control group (P<0.05);the serum level ofCRP,TNF-oα,IL-6 levels were significantly decreased compared with those before therapy,and those of observation group were obviously lower than the control group (P<0.05);the total effective rate of ob servation group was 94.55% (52/55),which was equivalent to the control group (89.23%,P>0.05);the long term memory,short term memory,instantaneous memory and memory quotient of observation group were significantly higher than those of the control group.Conclusion:Hyperbaric oxygen plus magnetic stimulation and Xingnaojing injectionon was effective on the coma patients with severe brain injury,it could down-regulate the inflammatory response,promote awake and recovery of memory function.

OBJECTIVE To investigate the correlation between benign paroxysmal positional vertigo (BPPV) and bone mineral density (BMD) in menopausal women with BPPV.METHODS 50 patients between the ages of 50-80 years old of menopausal women with Idiopathic benign paroxysmal positional vertigo(iBPPV)as case group,and postmenopausal healthy people of same age doing physical examinations in hospital medical examination center were selected as control group.The lumbar spine(L1-L4) and femoral neck were measured respectively using dual energy X-ray absorptiometry and expressed in T value.The case group and the control group were divided into three age groups,and the T values of three age groups were statistically analyzed.RESULTS There was significant correlation between the case group and control group(The t values are-3.68、-5.98 and-3.33,respectively,P<0.05).Pearson correlation analysis showed that there was a negative correlation between iBPPV and bone mineral density(BMD) (r=-0.496,P<0.05).CONCLUSION There was a correlation between benign paroxysmal positional vertigo and BMD in menopausal women.The results of this study may be helpful for the diagnosis,treatment,prognosis and precaution of iBPPV.

BACKGROUNDThe bacterial endotoxins test (BET) is a method used to detect or quantify endotoxins (lipo-polysaccharide, LPS) and is widely used in the quality control of parenteral medicines/vaccines and clinical dialysis fluid. It is also used in the diagnosis of endotoxemia and in detection of environment air quality control. Although BET has been adopted by most pharmacopoeias, result judgment algorithms (RJAs) of the test for interfering factors in the BET still differ between certain pharmacopoeias. We have evaluated RJAs of the test for interfering factors for the revision of BET described in the Chinese Pharmacopoeia 2010 (CHP2010).
METHODSOriginal data from 1 748 samples were judged by RJAs of the Chinese Pharmacopoeia 2010, the Japanese Pharmacopoeia 2011 (JP2011), the European Pharmacopoeia 7.0 (EP7.0), the United States Pharmacopoeia 36 (USP36), and the Indian Pharmacopoeia 2010 (IP2010), respectively. A SAS software package was used in the statistical analysis.
RESULTSThe results using CHP2010 and USP36, JP2011, EP7.0, and IP2010 had no significant difference (P = 0.7740). The results using CHP2010 of 1 748 samples showed that 132 samples (7.6%) required an additional step; nevertheless there was no such requirement when using the other pharmacopeias. The kappa value of two RJAs (CHP2010 and EP7.0) was 0.6900 (0.6297-0.7504) indicating that the CHP2010 and other pharmacopoeias have good consistency.
CONCLUSIONSThe results using CHP2010 and USP36, JP2011, EP7.0, and IP2010 have different characteristics. CHP2010 method shows a good performance in Specificity, mistake diagnostic rate, agreement rate, predictive value for suspicious rate, and predictive value for passed rate. The CHP2010 method only had disadvantages in sensitivity compared with other pharmacopeias. We suggest that the Chinese pharmacopoeia interference test be revised in accordance with the USP36, JP2011, EP7.0, and IP2010 judgment model.
