OBJECTIVE:To observe the protective effect of Zhuyu annao pill on model rats against cerebral hemorrhage. METHODS:The experimental rats were randomized to 6 groups:blank group,model group,Angong liuhuang pill group,Zhuyu annao pill high,medium and low dosage groups. Cephalophyma model of rats were duplicated with rats' autoblood clot; the neurologic impairment change was recorded by integration method; the water content of the brain tissue was measured by dry-wet specific density method; meanwhile,the changes in hemorheology,blood coagulation (4 parameters),the blood coagulation time and the histology of the morphology of brain tissue were observed. RESULTS:In rats treated with Zhuyu annao pill (high,medium or low dosage) as compared with model group,no significant change was noted in the water content and neurological impairment; however,the pro-time (PT) was significantly prolonged(P

Objective To investigate the possible role of mycobacterial infection in the pathogenesis of sarcoidosis.Methods DNA fragments of mycobacterial16S rRNA gene and the complex-specific insertion sequence IS6110of M.tuberculosis were detected by polymerase chain reaction(PCR)in formalin-fixed,paraffin-embeded skin biopsy specimens from12patients with sarcoidosis.Results Mycobacterial common sequence16S rRNA gene was found in6patients,among which5were further confirmed as M.tuberculosis,the other one was atypical mycobacteria.The IS6110DNA fragment amplified by PCR was confirmed by DNA sequencing.Conclusion The above findings suggest an aetiological role of mycobacterial infection,especially M.tuberculosis,in some patients with sarcoidosis.

Gastric cancer stem cells are defined as a subset of gastric cancer cells that possess stem cell properties,including self-renewal and multiplex differentiation potential,and have crucial roles in tumor initiation,progression,invasion,metastasis and recurrence.Epithelial-mesenchymal transition (EMT) can facilitate the invasion and metastasis of cancer cells to distant tissues,and confer the metastatic cancer cells some abilities of stem cells.Several transcription factors of EMT,signaling pathways and microRNAs (miRNAs) are involved in the process of regulating gastric cancer stem cells.

Objective: To analyze the problems of large medical equipment allocation in our country, put forward the method and basis of scientific configuration. Methods: The current situation of large medical equipment allocation was analyzed by the methods of literature, statistics and analysis, in order to understand the operating costs and benefits and provide a scientific configuration tool when bringing in medical technology. Results: The configuration of large medical equipment has some problems, such as the uneven distribution of medical resources, equipment shortage, blind purchase of high-end equipment, low localization rate and so on. These problems will directly lead to the unreasonable allocation and the waste of medical resources. Conclusion:The configuration of large medical equipment must comply with the relevant provisions of the state by the HTA and other scientific methods, so as to improve the level of investment decision-making. It will make the use of medical resources efficiently and reasonably.

Nowadays,more and more basic and clinical researches on absorbable internal fixators are car- fled out in China.This paper reviews the recent researches on biodegradation,absorption,and mechanical prop- erties of absorbable internal fixators,their effects on bone mineral density and structure and injury of epiphyseal plate,and their clinical applications.Some problems that have not been solved and future research key points are highlighted and discussed.

For the children,viral encephalitis is a common infectious disease of central nervous system,which is characterized by high incidences,unfavourable prognosis and high mortality rate.The Japanese encephalitis virus,herpes simplex virus,enteroviruses,EB virus,cytomegalovirus are the common pathogens.There are some emerging virus also cause encephalitis,such as west nile virus,borna disease virus,banna virus,nipah virus and so on.It is of significance for the doctors and scientific research personnels to study the pathogens of viral encephalitis.

Objective To summarize and analyze the failure reason of internal fixation operation in peritrochanteric fractures and propose appropriate prevention measures.Methods The clinical data of 229 patients with peritrochanteric fractures were retrospectively analyzed,the failure reason of internal fixation was analyzed by the univariate and multivariate Logistic regression analysis.Results The univariate analysis showed that the patients' age,gender composition,types of internal fixation had no significantly correlated with the failure of internal fixation (P ＞ 0.05) ; the Garden reset index,bone quality,fracture type and load time had significantly correlated with the failure of internal fixation (P ＜ 0.05).The multivariate Logistic analysis showed that load time was the independent risk factors for fixation failure (OR =13.515).Conclusion The weight-bearing time points should be selected according to the bone quality,fracture type,and degree of intraoperative reset,thereby reducing the risk of surgery failure.

Objective To study the effect of transmembrane tumor necrosis factor-alpha (TM-TNF-αt) on human cervical carcinoma HeLa cells,and explore the correlations with silencer of death domain (SODD).Methods The expression of proliferating cell nuclear antigen (PCNA) was detected by immunocytochemistry.The expression of SODD in human cervical carcinoma HeLa cells undisposed and after disposed with TM-TNF-α was detected by reverse transcription-polymerase chain reaction,and the influence of TM-TNF-α on human cervical carcinoma HeLa cells was analyzed.Results The positive rate of PCNA in undisposed human cervical carcinoma HeLa cells was 80.3％ (155/193),in human cervical carcinoma HeLa cells disposed with TM-TNF-α was 46.7％ (85/182),there was statistical difference (P ＜ 0.05).The cycle index of polymerase chain reaction in human cervical carcinoma HeLa cells was 28 times,the amplification product was disposed by 2％ agarose gel electrophoresis,the gray scale disposed by TM-TNF-α and undisposed human cervical carcinoma HeLa cells were 1.377 ± 0.170 and 0.815 ± 0.040,there was statistical difference (P ＜ 0.05).Conclusion TM-TNF-α has obvious cytotoxic effect on human cervical carcinoma HeLa cells in vitro which may due to its up-regulating the expression of SODD.

Radiotherapy and chemotherapy are the main treatment means for locally advanced squamous cell carcinoma of the pharynx and larynx, to guarantee efficacy and avoid the damage of radical surgery, so as to preserve the laryngeal function of swallowing and pronunciation.With the progressing of radiotherapy technology,concept of treatment and radiotherapy mode have been advanced constantly,that have prolonged the survival time and improved the quality of life.This study will review the progress of radiotherapy in the pharynx and larynx squamous cell carcinoma, investigate the improvement of radiotherapy technology and hypofractionated IMRT, and provide reference for reducing the toxicity and after effects of radiotherapy.

Objective To analyze the development status worldwide of nutriology,so as to provide an orientation of its development in the future.Methods The professional articles published were retrieved by information research methods to predict the focal problem,and to provide the demand and presumption of nutriology development.Results In the past 5 years,some innovative concepts and technics were widely used in nutrition studies,such as nutritional genomics,nutritional proteomics and systematic biology,etc.These technologies made it possible to study the influences of nutrients on gene and protein expression,and reversely,the influences of gene changes in nutrient related disturbances in metabolism.Advances in clinical nutritional therapy provides patients with a variety of clinical treatment and the possibility of earty rehabilitation.At present,there are some problems in the fields of nutritional therapy in our country,such as a lack of resource of professional staff,imperfect education system,deficiency in understanding the importance of nutriology,and the lag of standardization and normalization of nutrition information.Conclusions The progress of nutriology in coming five years should lay stress on the parallel development of individual and nationwide health level.A series of studies in molecular biology and systematic biology will upgrade the national physical quality and the basic health condition of population nationwide.
