Objective To investigate the respiratory function of platelet mitochondria in patients with Parkinson's disease(PD) and explore the assosiation with the pathogenesis of PD.Methods The platelet mitochondria of 35 patients with PD were extracted and the mitochondria respiratory rate and respiratory control rate were measured.Furthermore,the changes of activities of mitochondria complex Ⅰ,Ⅱ,Ⅲ and Ⅳ were observed.Results The platelet counts of patients with PD showed no changes, but the respiratory rates of respiratory state 3 were significantly decreased using the 5 mmol/L glutamate,2.5 mmol/L malate +5 mmol/L pyruvate and 5 mM succinate as substrates. Moreover, the activities of mitochondria complex Ⅰ were obviously reduced and the activites of other mitochondria complex were no changes.Conclusion Patients with PD show exactly abnormal mitochondria respiratory functions, and it might be an important mechanism in the pathogenesis of PD.

This study was aimed to explore the influence of extreme environment changes on the lung immune function in rats. Artificial climate system was used to simulate six extreme weathers, which were the sudden temperature increase (ZS), sudden temperature drop (ZJ), continuous high temperature (CG), continuous low temperature (CD), high temperature and high humidity (GWGS), normal temperature and high humidity (CWGS). And then, the method of enzyme-linked immunosorbent assay (ELISA) was adopted to detect bronchoalveolar lavage fluid (BALF) and related immune substances in lung tissues. The results showed there was significant difference of ZJ on IL-10 (P<0.05). There were significant differences of CG, CD, GWGS, and CWGS on IL-6, INF-γ and sIgA (P<0.05). Contents of the GWGS group and CWGS group were higher than that of the CG group and CD group. There was very significant difference on IL-10 in the CD group (P<0.01). It was concluded that the extreme environment changes had different influence on body’s immune. And different intervention factors cause the body’s immune factors to response accordingly.

OBJECTIVE:To optimize the content determination conditions of total alkaloids from Zhuang medicine Munronia delavayi,and to determine the content of total alkaloids in M. delavayi from different producing areas. METHODS:With the con-tent of total alkaloids as index,using solvent amount,ultrasonic time,ultrasonic extraction times and pH value of buffer as fac-tors,the content determination conditions of total alkaloids from Zhuang medicine M. delavayi were optimized by orthogonal test. Optimized content determination conditions were adopted to determine the content of total alkaloids in M. delavayi from 18 produc-ing areas in different harvest time. RESULTS:The optimum content determination conditions were as follows as the amount of sol-vent(CHCl3)20 ml,ultrasonic processing for 3 times,lasting for 15 min each time,pH value of buffer 4.5. The contents of total alkaloids in M. delavayi from 18 producing areas were between 0.6-11.98 mg/g,showing great difference. M. delavayi from Long-lin county and Tianlin county harvested in Oct. had the lowest content of total alkaloids. CONCLUSIONS:Optimized content deter-mination condition can be used for the content determination of total alkaloids in Zhuang medicine M. delavayi and quality control of it. The content determination of total alkaloids in M. delavayi is related to producing area and harvest time.

AIM: To investigate the role of CagA and the effect of small interference RNA (siRNA) on the release of IL-8 in H. pylori-infected gastric epithelial cells. METHODS: siRNA were transferred into CagA positive strain H. pylori NCTC 11637 by using electroporation. The CagA positive strain NCTC 11637 and the CagA negative strain NCTC 11639 were co-cultured with gastric epithelial cells and the level of IL-8 in the supernatant was measure by ELISA. RT-PCR and Western blotting were performed to detect CagA expression. RESULTS: The level of IL-8 induced by CagA positive strain NCTC 11637 was higher than the level induced by CagA negative strain NCTC 11639 ( 1 200.00 ?32.51) ng/L vs (100.00?8.58) ng/L, P0.05). Meanwhile, CagA mRNA decreased significantly in siRNAⅢgroup. The levels of CagA mRNA at 6, 12, and 24 h after electroporation were 31.3% (0.270/0.861), 57.6% (0.496/0.861), and 73.9% (0.637/0.861) of the control levels, respectively. Inhibition rate by siRNAⅢ was 68.7%. The Western blotting result in siRNA Ⅲ group showed that the level of CagA protein degraded to 30.7% (0.4/1.3) at 12 h after electroporation. In siRNA V group, the expression of CagA mRNA at 6 h is suppressed by 23.1% (P

Objective To investigate the expression of type Ⅱ collagen in the articular chondrocyte of osteoarthritis (OA) patients and normal human. Methods The samples of articular cartilage were obtained from the patients undergoing total joint replacement, including 8 primary OA patients, 8 secondary OA patients and 9 normal subjects. Type Ⅱ collagen expression in chondrocyte was detected by reverse transcriptase polymerase chain reaction (RT-PCR). Results The expressin of type Ⅱ collagen mRNA in normal OA group was higher than that in primary OA group and secondary OA group with a statistical difference (P=0.014), while there was no statistical difference between primary OA group and secondary OA group(P=0.716). Conclusions The reduction of type Ⅱ collagen expression leads to the change of collagen directly and possibly plays an important role in OA, which is the common pathway of the occurrence of both the primary and secondary OA.

Objective: To compare the efifcacy and safety of circumferential pulmonary vein antecourt isolation (CPVAI) ablation and stepwise linear (SL) ablation in treating the patients with atrial ifbrillation (AF) Methods: A total of 136 AF patients with catheter ablation under EnSite 3000 guidance in our hospital were retrospectively summarized. The patients included 93 paroxysmal AF and 43 persistent AF and divided into 4 groups. Paroxysmal AF with CPVAI ablation,n=45, Paroxysmal AF with SL ablation,n=48 and persistent AF with CPVAI ablation, n=18, persistent AF with SL ablation,n=25. The differences of left atrium diameter, ablation time, X-ray exposure time, the success rate and complication were compared among different groups. Results: For 12 months follow-up study, the success rate and complication were similar between 2 ablation methods for treating both Paroxysmal AF and persistent AF patients. For Paroxysmal AF patients, both ablation methods could effectively reduce left atrium diameter,P<0.01. The SL ablation had less procedural time than CPVAI ablation,P<0.01, while the X-ray exposure time was similar between 2 ablation methods. Conclusion: Both CPVAI and SL ablation methods were effective and safe for treating AF patients.
