Objective To evaluate the effect of transitional care on the quality of life in patients with maintenance hemodialysis (MHD).Methods 101 MHD patients with symptoms of kidney ＜ 80 points were assigned into the interventional group (47 of 51 cases completed the study) and the control group (45 of 50 cases completed the study) by random number table method.The patients in the interventional group received transitional care for 6 months,while control group received routine care.The effects on function index,satisfaction index and clinical index were evaluated at the 3rd month and 6th month after intervention.Results 6 months after intervention,the scores of physical composite,mental composite,burden of kidney disease,symptoms/problems list,effects of kidney disease in the interventional group were 51.78±5.91,55.32±5.36,29.79±17.64,79.39±6.73,68.02±11.38,while the scores of the control group were 38.22±9.46,42.03±8.32,19.58±17.25,69.49±10.10,52.09±16.78,and the difference between the two groups was statistically significant (t=5.308-9.063,Z=-3.07,P ＜ 0.01).The scores of self-management behavior,health locus of control in the interventional group were 71.30-±5.42,25.74±2.42,while the scores of the control group were 65.0±8.74,22.47±3.97 (t=4.132,4.759,P ＜ 0.01).The nursing satisfaction in the interventional group scored 91.06±7.29,which was significantly higher than the control group scored 86.22±10.72 (Z=-2.45,P＜ 0.05).The level of serum phosphorus (PO4),Ca × PO4 products,parathormone (PTH) in the interventional group were (1.76±0.35) mmol/L,(51.02±10.04) mg2/dl2,464.56 ng/L,which were significanlty lower than (2.01±0.54) mmol/L,(57.41±17.38) mg2/dl2,625.78 ng/L in the control group (t=-2.691,-2.167,-2.000 in tum,P ＜ 0.01 or 0.05).Conclusions Transitional care achieves good effectiveness on the quality of life in patients with MHD.

Objective To improve the level of diagnosis and treatment of the sharp injury in the back. Methods 47 cases which were treated from Jan 1991 to May 2000 were reviewed. ResultsAmong 37 cases who underwent the exploration, 5 cases died. Among 10 cases who underwent conservative treatment, 2 cases died. ConclusionThe condition of sharp injury in the back is very complicated,it is easy to be misdiagnosed, the mortality is high. Saving should be equalled with the diagnosis and treatment. The application of wound exploration, abdominal puncture, ultrasound examination and X-ray checking is valuable to the diagnosis. The patients with operation indications should be operated at once,while the others should be observed for some time to prevent the delayed clinical manifestation.

Objective The analysis of correlation between the occurrence of tourette syndrome with one-child family environment. Methods The authors investigated home environment of two groups. One group included 200 patients with tourette syndrome and is the other group included healthy children of the same age in 3 different primary and secondary schools. By comparing with the home environmental factors, parenting styles and parent emotional factors between two groups. Results The instabilities of home environment included bad family relationship, separation between parents, divorce, scolding and even beating children. It showed that anxiety of the direct supervisors among the sickness group were higher than healthy control group as well. Among the ten factors of the Family Environments Scale, the significant differences showed in six factors of affection,cohesion,expressiveness, conflict, intellectual-culture orientation, active-recreational orientation, organization between the two groups. Conclusion So we concluded that ①There is a correlation between the parents relations,parenting styles and the incidence of tourette syndrome; ②An anxiety of the direct supervisor may initiate, even aggravate the incidence of tourette syndrome; ③It is important to convert the education mode and take family overall treatment in order to reduce the incidence and improve the effectiveness of tourette syndrome.

Objective To investigate the immunological properties of Rv1009 domain. Methods BALB/c mice were immunized with Rv1009 domain three times at 2-week interval. ELISA was used to detect the antiRv1009 domain antibody titer in the sera of immunized mice sera. The spleen lymphocytes of the immunized mice were separated and the stimulation index (SI) was measured by MTT colorimetry. Levels of secreted IFN-γ, IL-10 and IL-12 upon specific antigen stimulation were detected by ELISA. The BALB/c mice immunized with Rv1009 domain were intravenously infected with MTB H37Rv. Four weeks after the final injection, the number of CFU in spleens was determined. Results The titer of the specific antibody in sera of the immunized BALB/c mice was 1:12 800. The SI of Rv1009 domain immunized group (2. 40±0. 18) was significantly higher than that of saline immunized group (0.90±0.21). The IFN-γ,IL-10 and IL-12 levels in culture supematant of spleen lymphecytes from the fusion proteins immunized mice was (1 432±30) ng/L, (503±11) ng/L and (311±11) ng/L respectively, significant different from that of saline immunized group[(256±20) ng/L, (76±6) ng/L and(56±8) ng/L,P<0.01]. Four weeks after the final injection,compared with normal saline immunized mice (6.64±0.13), dramatic reduction in MTB replication was observed in the spleen (4.86±0.14) from BALB/c mice immunized with fusion proteins following a subsequent MTB H37Rv challenge, but the protection efficacy of mice immunized with Rv1009 domain was not as good as that of BCG vaccination group (3.81±0.16). Conclusion Rv1009 domain can be used as a candidate for the new TB vaccine.

The study is aimed to understand the resource and the current situation of the use of Cibotii Rhizoma and provide the basis for protecting and utilization. The method of literature survey, field survey and quality assessment were applied in the study. The results showed that all the Cibotii Rhizoma came from wild resource and was mainly founded in Fujian, Guangxi, Guizhou, Yunnan, Guangdong, Hunan, Jiangxi, Sichuan, Chongqing, Zhejiang, etc. It contains over 5 000 000 kg in the area which total is about 7 000 hm2. The annual output is over 850 000 kg. At present, there is no cultivated resources. Based on the investigation and market sampling analysis from various regions, the results showed that the quality of the collected crude drugs conformed with the regulations of the Chinese pharmacopoeia. However the qualification rate of decoction pieces of Cibotii Rhizoma in market was only 56.4%. At present, the resource of Cibotii Rhizoma could meet the needs of medinal uses. It is important to protect the wild resource which is less and less because of the environmental factors. It also need to make a standard of processing method to ensure the safety, and solve quality problem of the decoction pieces.

Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.
