Thirty-six subclinical hypothyroidism patients with different pathogenic background were treated by levothyroxine. After treatment the levels of serum total cholesterol, low density lipoprotein and triglyceride were significantly lower than those before treatment (P

AIM: To study the effect of estrogen on injury induced by ?-amyloid protein (A?) in primary cultures of rat cortical neurons. METHODS: The effect of 17?-E_2 on A?(25-35)-induced cell death in primary rat cortical neurons was observed by phase contrast light microscopy, Giemsa staining and determination of lactate dehydrohenase (LDH) release rate. RESULTS: A?(25-35) induced cell death in rat primary cortical neurons. Forty eight hours pretreatment with 17?-E_2 protected rat primary cortical neurons from A?(25-35)-induced injury. CONCLUSION: A? evokes toxicity in rat primary cortical neurons. Estrogen can protect the rat primary cortical neurons against injury induced by A? (25-35).

Bioeleotrical activities of human cerebral cortex which control and regalate movements get to increase during voluntary movements, the metabolic level of the cells of motor areas change at the same time,and consequently regiond cerebrd blood flow (rCBF)changes. Different changes of rCBF indicate the range of motor areas with which the relavant movemats are involved.And studies of this take great significance in finding out the basic active regalarity and features of human brain. In this artide motheds of the determination of rCBF an introduced briefly, and changes and distribution of rCBF of rCBF of each cortical moter area during different types of volantary movements are discribed.

Objective To evaluate the clinical effect of treating chloasma with acupuncture and bloodletting therapy.Methods 176 cases with chloasma were recruited into two groups randomly. Acupuncture and bloodletting therapy was adopted in the treatment group (90 cases), and exclusive acupuncture was applied in the control group (86 cases). Results The effective rate was 96.7% in the treatment group and 51.2% in the control group. There was a significant statistical difference between two groups (P＜0.05). Conclusion The treatment of acupuncture and bloodletting therapy has a definite therapeutic effect on chloasma, being worthy of spread.

OBJECTIVE To search the methods of decreasing the missing report of nosocomial infection cases with a prospective monitoring method.METHODS To summarize the methods and measures that had been adopted for ten years.RESULTS There were four important means to decrease the missing report of nosocomial infection cases with a prospective monitoring method.The measures included combining prospective monitoring method and(retrospective) monitoring method at the beginning of taking prospective monitoring method,taking the right(methods),devising careful and precise researching procedure,reinforcing to propagandize and educate the(knowledge) of nosocomial infection to enhance the understanding of medical personnel to control nosocomial(infection),and analyzing and feedbacking the data of nosocomial infection with a prospective monitoring method.CONCLUSIONS It is necessary to develop the prospective monitoring method of investigating nosocomial(infection) as perfectly as possible.It can not only decrease the missing report of nosocomial infection with(prospective)(monitoring) method,but also effectively clue on trend of outbreak and epidemic of nosocomial infection.

Liver diseases post great threats to human public health globally.Lacking of appropriate small animal models largely impeded the translational studies on human liver diseases, especially on viral hepatitis and related cirrhosis, hepatocellular carcinoma, etc.By human hepatocyte transplantation, the liver-humanized mice have significantly contribu-ted to the researches of human liver diseases.This review summarizes the currently widely used and representative human-ized mouse models, including uPA, FAH, TK-NOG, AFC8 mice and their applications in studies of human liver diseases.

Granzyme B is an important effect factor of cytotoxic T lymphocytes in the immune killer function,can quickly induce cell apoptosis of the target cell.It is complicated for the reasons and the ways of the occurrence of the cell apoptosis,many genes are involved in gene regulation of cell apoptosis,and the B-cell lymphoma/leukemia-2 gene family members play a crucial role in the process of cell apoptosis.This paper mainly reviews the correlation of GrB and Bcl-2,Bid with cell apoptosis.
