Chinese Pediatric Emergency Medicine 2011;18(5):397-399,402
Increased intracranial pressure is one of the most severe complications with significant mortality in children,so early diagnosis and treatment of this disorder is critical to save the patient's life.This article reviews etiologies,pathophysiology,and general principles of diagnosis and management of increased intracranial pressure.Based on primary diseases and clinical presentations,the goal of therapeutic strategy is to decrease intracranial pressure,avoid neurologic sequelae,and improve the outcome in patients.
2.The clinical status research on the integrated Chinese medicine and western medicine
Chinese Journal of Primary Medicine and Pharmacy 2017;24(1):142-145
Integrative medicine is the effective combination of dual diagnosis of Chinese medicine and western medicine.The combination can broaden the scope of clinical diagnosis and combine the local pathological changes with the overall response of the human disease.It can add a more comprehensive understanding of diseases for people.Clinically treated with combination of Chinese medicine and western medicine can achieve the complement of advantages.It is significant.Because the theory system of Chinese medicine compared with western medicine is different and the theory system of combination is not practical and standardized.The methods of clinical diagnosis and treatment are also different.So there are still some problems and deficiencies in the integrative medicine.In this study,through extensive literature research,as well as the clinical investigation in some integrative medicine hospitals and the collection of related clinical data,we compared and analyzed the academic ideas and different features of Chinese medicine and western medicine,analysed the status and the insufficience of current clinical integrative medicine.Finally,we put forward a series of effective strategies and methods for how to combine with integrative medicine in a specific,reasonable and effective way.

Influenza virus is a continuous and severe global threat to mankind.The continuously re-emerging disease gives rise to thousands of deaths and enormous economic losses each year,which emphasizes the urgency and necessity to develop high-quality influenza vaccines in a safer,more efficient and economic way.The influenza subunit and VLP vaccines,taking the advantage of recombinant DNA technologies and expression system platforms,can be produced in such an ideal way.This review summarized the recent advancements in the research and development of influenza subunit and VLP vaccines based on the recombinant expression of hemagglutinin antigen (HA),neuraminidase antigen (NA),Matrix 2 protein (M2) and nucleocapsid protein (NP).It would help to get insight into the current stage of influenza vaccines,and suggest the future design and development of novel influenza vaccines.

Objective:To investigate the distribution of TNF microsatellite polymorphisms in Chinese Han population of Hubei province Methods:DNA samples were extracted from 164 unrelated healthy individuals’EDTA blood TNF microsatellite alleles were typed using PCR technique,followed by High Voltage denaturing PAGE,with silver staining At the same time,the PCR products were cloned and sequenced Results:Detected seven alleles and eleven kinds of genotypes at the TNFb locus;four alleles and seven kinds of genotypes at the TNFe locus The polymorphism information contents (PIC) were 0 67 and 0 33 respectively No deviation from Hardy Weinberg equilibrium were observed Statistical analysis showed,the distribution of TNFb and TNFe alleles in Chinese Han population were significantly different from that in European or in American Caucasian(P
6. Protection of puerarin on impaired vascular endothelial function induced by glycosylated protein
Chinese Pharmaceutical Journal 2014;49(7):559-563
OBJECTIVE: To investigate the effects of puerarin on impaired endothelium-dependent relaxation induced by glycosylated bovine serum albumin (GBSA) in rabbit thoracic aorta and its mechanisms. METHODS: The rings were incubated with GBSA for 30 min to induce endothelial dysfunction, and with puerarin(0.25, 0.5 and 1 g · L-1), A-nitro-L-arginine methyl ester (L-NAME, 30 νmol · L-1), and indomethacin(10 μmol · L-1) to investigate the protective effect of puerarin on impaired vascular endothelial function elicited by GBSA, and the effect of L-NAME and indomethacin on the protective effect of puerarin. Moreover, the content of nitric oxide (NO) and malonaldehyde (MDA) and the activity of superoxide dismutase(SOD) in the rings were measured. RESULTS: Exposure of aortic rings to GBSA (200 mg · L-1) for 30 min resulted in a significant inhibition of endothelium-dependent relaxation, but had no affect on endothelium-independent relaxation. GBSA significantly decreased the level of NO and the activity of SOD but hugely increased the content of MDA in vascular tissues. Pre-incubation of aortic rings with puerarin markedly attenuated the inhibition of endothelium-dependent relaxation induced by GBSA. This protective effect of puerarin (1 g · L-1) was partially inhibited by L-NAME but not by indomethacin. Puerarin obviously increased NO level and SOD activity but evidently decreased MDA content in rings. CONCLUSION: Puerarin can protect against vascular endothelial dysfunction caused by GBSA and its mechanisms may be related to enhancing NO synthesis and its anti-oxidation.

Objective To explore the expression of SLAM gene in the CD4+ and CD8+ T cells from SLE patients.Method The CD4+ and CD8+ T cells from peripheral blood of 20 SLE patients and 10 healthy blood donors were separated using magnetic cell sorting system(MACS).We detected the expression of SLAM mRNA in CD4+ and CD8+ T cells by RT-PCR.Results The CD4+ and CD8+ T cells from SLE patients showed significantly higher SLAM expression than those from healthy blood donors.Conclusion The SLAM signal pathway may play an important role in contributing to the abnormal activation of T cells in SLE patients.

0.05). Conclusion There are MA and mutation of p53 gene in T-cell lymphoma though no significant correlation between them. But, MA positive cases might experience high mutation of p53 gene in T-cell lymphoma.

Objective To investigate whether tumor necrosis factor (TNF)a, TNFb and TNFc microsatellite polymorphisms correlate with chronic atrophic gastritis and gastric adenocarcinoma in Chinese Han population. Methods TNFa, TNFb and TNFc microsatellite alleles in 164 healthy subjects, 53 patients with chronic atrophic gastritis and 56 patients with gastric adenocarcinoma were typed using PCR technique combined with High Voltage denaturing PAGE and silver staining. At the same time, the PCR products were cloned and sequenced. Results The frequency of TNFa10 allele was significantly higher in patients with chronic atrophic gastritis than in healthy individuals ( 19.81% vs. 11.89% , P = 0.04 ). However it was not related to age, gender, degree of atrophy or intestinal metaplasia in patients with chronic atrophic gastritis. The frequency of TNFa6b5c1 haplotype homozygote was significantly lower in patients with gastric adenocarcinoma than in healthy individuals ( 1.79% vs. 15.85% , P = 0.006 ). The sequence result revealed that the copy number of dinucleiotide repeating within the same TNFa allele was not consistent with that in the reports from Western countries. Conclusions It should be more accurate and clear to define TNFa alleles. TNFa10 allele is associated with the susceptibility to chronic atrophic gastritis. TNFa6b5c1 haplotype homozygote is negatively associated with gastric adenocarcinoma and thus may play a resistant role in the shifting process from chronic atrophic gastritis to gastric adenocarcinoma.

Objective:To study the effect of retinoic acid (RA) and basic fibroblast growth factor (bFGF) on neural stem cells’(NSCs) proliferation and differentiation from new born rats’ pallium. Method: NSCs were isolated from the brains of new born Sprague-Dawley rats’ pallium, and the features of cells were characterized by immunofluorescence staining. The effects of different culture medium on survival and proliferation of cells were determined by MTT assay. The effects of bFGF and RA on differentiation of NSCs were observed. Results: MTT assay indicated the proliferation of cells in bFGF group, bFGF+RA group and RA group was continually increased, highest in bFGF group. The percentage of neurons differentiated from NSCs in RA group was 2 or 3 times that in bFGF group and control group . Conclusion: bFGF is important to the proliferation and long-term living of NSCs. It can prohibit the differentiation of NSCs. RA can counteract the effects of bFGF and also promote NSCs to differentiate into neurons in vitro.
