Objective: To observe influence of aerobic exercise on blood pressure in patients with white coat hypertension (WCH). Methods: A total of 51 newly diagnostic WCH patients were randomly divided into exercise group (n=26) and WCH control group (n=25). Patients in exercise group received aerobic exercise training (walking on flat ground by constant speed, twice a day, 50~80 min each time for three months); The WCH control group did not exercise. Office blood pressure (OBP) and 24h ambulatory blood pressure monitoring (ABPM) were measured in both groups before and three months after treatment. Results: There were no significant difference in indexes of OBP and ABPM between two groups before treatment (P>0.05). After three months, compared with before treatment, indexes of OBP and ABPM significantly decreased in exercise group and they were significantly lower than those of WCH control group in OBP [OSBP: (132.54±17.60) mmHg vs. (143.68±20.35) mmHg, ODBP: (89.12±18.39) mmHg vs. (92.75±17.24) mmHg] and ABPM [ mSBP：(121.57±20.86) mmHg vs. (128.06±19.45) mmHg, mDBP：(76.24±15.28) mmHg vs. (84.55±17.31) mmHg; dSBP：(124.27±22.50) mmHg vs. (130.85±24.61) mmHg, dDBP：(77.95±18.42) mmHg vs. (82.36±17.59) mmHg], P<0.05~0.01. Conclusions: Aerobic exercise can significantly improve blood pressure in patients with white coat hypertension.

Objective To observe the efficacy of the combination of moxibustion and pressing beans on auricular in the treatment of elderly patients with chronic diarrhea.Methods 45 elderly patients met the diagnostic criteria for diarrhea were divided into two groups,the treatment group (23 cases) received the treatment of combined moxibustion with ear pressure beans,the control group (22 cases) received traditional Chinese medicine treatment.The efficacy was observed and compared after two weeks.Results The effective rate reached 95.6％ in the treatment group,81.8％ in the control group (statistically significant difference,odds ratio 1.16).Conclusion Combined ear pressure beans with moxibustion treatment will receive a significant effect for the elderly patients with chronic diarrhea.The therapy is worth clinical application.

Objective:To investigate the effects of 17-? estradiol (E2) on the proliferation and metastasis of adenoid cystic carcinoma SAcc83 cells.Methods:The effects of E2 on the proliferation of SAcc83 cells were studied by MTT assay and flow cytometry.The invasion potential of the cells was investigated with chicken embryo heart invasion assay.The in vivo growth and metastasis of SAcc83 cell induced tumor were studied in ovary-resected female nude mice. Results:E2 at 10 -7 ,10 -8 and 10 -9 mol/L promoted the proliferation of SAcc83 cells. E2 at 10 -7 mol/L showed the strongest growth stimulation effects and increased the cell proliferation by 34.4%.With exposure time of 1,2 and 3 d it increased the proliferation index by 33.3%,40.9% and 17.8% respectively;with the exposure time of 12,18 and 24 h,it increased S phase cells in cell cycle by 12.3%,3.3% and 9.7% respectively. Neoplasm developed in all nude mice after subcutaneous transplantation of 106 cells.In the mice treated with 0.2 ml of E2 at 9.55 ?10 -5 mol/L every day for 15 days neoplasm volume doubling time was 61.5 h,that in control mice 76.5 h.In lung metastasis trial, 42 days after tail injection of the cells the metastasis foci in E2 treated mice inreased by 41.2%.Conclusion:E2 may increase the proliferation and metastasis of adenoid cystic carcinoma cells.

Objective:To study the expression and clinical significance of GPRC5A and SOCS3 in colorectal carcinoma.Methods:SP immunochemical method was performed to detect the expression of GPRCSA and SOCS3 in 45 cases of colorectal carcinoma,25 cases of colorectal adenomas and 22 cases of normal colorectal tissues.Results:1)Expression of GPRC5A in colorectal cancinoma tissue (22.2％) was significantly lower than that in adenomas tissue (52.0％,P＞0.05).The Latter was significantly lower than that in normal colorectal tissue (81.8％,P＜0.05).GPRC5Awas closely related to lymph node metastasis,Duke's stages and the deepness of invasion (P＜0.05).2) Expression of SOCS3 in colorectal cancinoma tissue (24.4％) was significantly lower than that in adenomas tissue (56.0％,P＜0.01).The Latter was significantly lower than that in normal colorectal tissue (86.4％,P＜0.05).SOCS3 was closely related to pathological differentiation,the deepness of invasion,Duke's stages and lymph node metastasis (P＜0.05).3)The expression of GPRC5A was positive correlated with SOCS3 (P＜0.05).Conclusions:The reduced expressions of GPRC5A and SOCS3 may participate in the occurence and development of colorectal carcinorma,suggesting that GPRC5A and SOCS3 may act as biological markers for evaluating the malign degree,prognosis and therapeutic targets of colorectal carcinorma.

Camptothecin is known to possess a broad spectrum of anticancer activities, however due to its high toxicity and low solubility in water, camptothecin is severely limited in clinic. To optimize the effects of camptothecin in the treatment of malignancies, besides the structural modification and reconstruction of camptothecin, the establishment of new drug delivery systems becomes a hot topic in the camptothecin research. This paper aims to summarize the advanced progress in the delivery system and function of camptothecin at recent years. The advances in improving the poor solubility, lactone ring instability, controlled release systems and targeting delivery systems of camptothecin are also reviewed. As the related methods and technologies are improved and developed, camptothecin will be a group of prospective anticancer drugs.

Considering a variety of theories such like Dunkin's, Centra's and Kolitch's, a set of 13 indicators are designed to evaluate effect of courses taken in high education of China currently, compro-mised by chief aspects of course designing, practicing, and effect. Three courses including medical nursing, humanistic cultivation and communication skills in nursing and fundamentals of nursing in a nursing de-partment are chosen to be objects of questionnaire survey about the above indicators. The results show that there are significant differences in curriculum effectiveness between different courses. The scores are 2.81, 2.80 and 2.60 respectively, and teachers and students have different evaluation on the same indicators of the same curriculum,which provides a reference for teachers, colleges and universities and teaching management departments to promote the improvement of teaching quality.

A set of specific primers was synthesized according to DNA sequence of HBV found in China, the reverse transcriptase (RT) region in polymerase gene was amplified by PCR method from the serum of 3 patients with chronic HBV infection, and then the PCR products were subcloned into pGEM Teasy vectors. 13 clones were sequenced. Sequence comparison of the selected clones was made to look for the difference. After being compared, 13 sequences of RT were found different. Besides 2 clones with long sequence deletion, the different rate of RT coding nucleic acid sequences, RT and HBsAg amino acid sequences of the 11 clones is 5 1%, 4 9% and 7 5%, respectively. Many mutation types, including point substitution and deletion mutation, were found in this region. There is quasispecies population and defective HBV genome in patients with chronic HBV infection.
