Objective　To evaluate the efficiency of low molecular weight heparin(LMWH, fraxiparine) given as a single predialysis bolus injection with reused dialyzers in comparison with standard heparin(SH) administered with a continuous infusion. Methods　30 hemodialysis patients were studied in a radomized crossover fashion. Dialyzers fibrer bundle volumes(FBV), predialysis hemocrit and 2 h clearance of urea, creatinine were observed in the first, the fourth dialysis. The plasma heparin activities(anti-Fxa levels) were measured by the chromogenic substrate assay in 0 h, 2 h, 4 h of dialysis. Results　Significant increase (P<0.05) was seen in the number of dialyzer reuse in LMWH group compared with SH group; there was not significant decrease in dialysis FBV as well as 2 h clearance of urea, creatinine (P>0.05); in addition, the plasma heparin activity(anti-Fxa levels) were comparable in both groups after 2 h of dialysis, however, they were significantly higher after 4 h in the LMWH than those in the SH group (P<0.05). Conclusion　LMWH as a single bolus dose can prevent decrease in dialyzer clearance. It is clinically worthy of further popularity.

Objective:To investigate the effects of Mycobacterium Phlei on functional states of Th_1/Th_2 in patients with chronic obstructive pulmonary disease(COPD),and clinical effects on the prevention of acute exacerbation of chronic obstructive pulmonary diseases(AECOPD).Method:60 patients with COPD of gradeⅡwere randomly divided into a treatment group and controlled group.The controlled group were given a routine therapy,while the treatment group were given utilins in addition to the routine treatment.The contents of?-interferon(IFN-?) and interleukin-4(IL-4) in their peripheral blood and their clinical efficacy were observed before and after the treatment.Result:Before and after the treatment, IFN-?/IL-4 ratio in the treatment group was 1.39?0.20 and 1.94?0.31 respectively(P

Objective To investigate the relationship between human epidermal growth factor receptor 2 (HER-2) gene amplification and protein expression in gastric carcinoma and its clinicopathological features. Methods Gene expression and protein expression of 98 gastric cancer patients were detected by fluorescence in situ hybridization (FISH), and immunohistochemistry (IHC) staining respectively. The relationship between gene amplification, protein expression of HER-2 and the clinicopathological characteristics were analyzed. Results In 98 cases of gastric cancer, there were 16.3 % (16/98) with gene amplification of HER-2, 83.7 % (82/98) without gene amplification of HER-2; 31.6 % (31/98) with negative expression of HER-2 protein, 59.2 % (58/98) with uncertain expression of HER-2 protein, 9.2 % (9/98) with positive expression of HER-2 protein. The coincidence rates of HER-2 protein expression and gene amplification were 96.7 % (30/31), 12.0 % (7/58), 88.9 % (8/9). The expression of HER-2 protein and gene amplification in gastric cancer was significantly correlated (P< 0.001). HER-2 gene amplification was not significantly correlated with gender, age, differentiation degree and depth of invasion (all P> 0.05), but with lymph node metastasis (P= 0.022). Conclusions The negative and positive expression of HER-2 protein have a high coincidence rate with gene amplification in gastric carcinoma. However, the results of IHC and FISH are different when the expression of HER-2 protein is uncertain. The amplification of HER-2 gene is associated with lymph node metastasis in patients with gastric cancer, which may provide an important reference index for determining the biological behavior of gastric cancer.

Objective To compare the effect of pedicles screw fixation through entry point of the “人" shape crest and traditional entry point (Weinstein method). Methods Ninety-two patients of lumbar spine disorders were treated by pedicles screw fixation combined with bone grafting through posterior approach. The screws were placed through the traditional entry point among 45 patients (group A, transverse process method, 186 screws), the others were through entry point of the “人" shape crest (group B, “人" shape crest method, 196 screws). The condition of accuracy of screw placement, operation time, bleeding amount and injury were compared. Results All patients accepted the examination of X-ray and CT scan after operation. The rate of screw bad placement was 6.5% in group A and 2.0% in group B, the incidence of injury of nerve and blood vessel was 8.9% in group A and 2.1% in group B. The accuracy of screw placement, operational time and bleeding amount in group B were significantly better than those in group A (P

Objective To explore the clinical efficacy of NEOVEIL in postoperative pulmonary air leakage of pulmonary bullae resection by video-assisted thoracic surgery. Methods We retrospectively analyzed clinical data of 37 cases received NEOVEIL combined with ATB45 in video-assisted thoracic surgery (the NEOVEIL group), and clinical data of 40 cases by ATB45 alone(the control group) . We compared postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary infection in the two groups. Results There was no postoperative mechanical ventilation,hemothorax and death. In the NEOVEIL group, the postoperative hospitalization time was 5 to 9 days, the postoperative keeping time of pleural cavity tubes 2 to 4 days, the postoperative pulmonary leakage time 0 to 2 days with 4 patients un-leakage, and 1 patients with pulmonary infection; whereas the postoperative hospitalization time was 6 to 10 days,the postoperative keeping time of pleural cavity tubes 3 to 6 days,the postoperative pulmonary leakage time 2 to 5 days and 8 patients with pulmonary infection in the control group. There was statistical significance in the postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary inflammation in two groups(P ＜ 0. 05). The incidence of pulmonary inflammation of the NEOVEIL group (2. 7%) was significantly lower than that of the control group(20. 0%)(x2 = 4. 02, P ＜ 0. 05). Conclusion The operative effectiveness of the NEOVEIL group is better than that of the control group. The NEOVEIL can prevent the postoperative pulmonary leakage.

BACKGROUND: Hepatocyte growth factor (HGF) promotes neurite outgrowth from neocortical explants, and supports neuronal survival under serum-free condition. Thus, HGF can mediate neurotrophic function as a novel neurotrophic factor.OBJECTIVE: To establish an in vitro injury model with a semi-solid culture system for the purpose of improving the evaluation of neurite regeneration of transected spinal cord neurons from rat embryo, and investigate the effect of HGF on neurite regeneration.DESIGN: Randomized controlled study.SETTING: Hematology Laboratory of Radian Medical Institute of Academy of Military Medical Sciences of PLA.MATERIALS: The experiment was carried out at the Hematology Laboratory of Radian Medical Institute of Academy of Military Medical Sciences of PLA from August 2004 to May 2005. Wistar fetal rats of 14-16 days old were provided by Animal Center of Academy of Military Medical Sciences of PLA. Tail collagen was extracted from adult male Wistar rats with body mass of (250±50) g.METHODS: ① Rat tail type Ⅰ collagen substrate was prepared and spread on a culture dish, cut into about 0.5-1.0 mm3 slices, then spinal cord slices of 15-day-old fetal Wistar rat were explanted on the primary culture. Five days later, the outgrowing processes were severed, then a block of collagen, with the surface area of 2 mm2 and 200 μm away from the slice, was removed and the vacancy was replaced with a fresh collagen block of 2 μL after aspirating the medium. The fresh collagen block could be solidified and then fresh liquid medium was added as the secondary culture. The regeneration of neurite was observed by microscopy at 0, 1, 6,12 and 24 hours after severing. ② The medium was changed with 0.5% N3-conditioned medium. 10 μg/L HGF was added in the experimental group, and 0.5% N3-conditioned medium was added in the control group.The status of regeneration was evaluated by the average value of 3 longest regenerative neurites for each slice. There were 12 slices in each group.The status of neurite regeneration was calculated and was evaluated 24 hours later.MAIN OUTCOME MEASURES: ① neurite regeneration in situ; ②comparisons of neurite regeneration between control group and experimental group.RESULTS: ① Neurite regeneration in situ: The neurites disintegrated near the severing line immediately following the transection injury. This process persisted about 1-2 hours and the distance away from the severing line was about 20 μm. Then the proximal end of neurites would swell and thicken. At this time neurites stopped collapsing and neurite regeneration began. Their regenerating rate would quicken at 12 hours after severing. Regenerating neurites were more branching and curlier as compared with original neurites. ② Comparisons of neurite regeneration between control group and experimental group: The average length of regenerative neurites was more in the experimental group than that in the control group [(375±96) μm, (200±75) μm, P ＜ 0.05].CONCLUSION: ① We establish a simple, economic model to evaluate neurite regeneration. ② By this model, we prove that HGF can promote neurite regeneration.

Objective From the angle of skeletal muscle ultrastructure and free radical metabolism,the paper explored the effect of vitamin E on skeletal muscle's damage after eccentric exercise.Methods 48 male Sprague Dawley rats were randomly divided into the control group,the sport group,the physiological saline group,and the vitamin E group.The model of animals was made by a bout of eccentric exercise on a treadmill.After the training,triceps brachiies were extracted from the right side of rats.Parts of triceps brachiies were made for microelectric slices,the others for the extracting of SR by the method of centrifugation at different speeds and for measuring the content of MDA and activity of SOD.Results In the vitamin E group,the muscular ultrastructures damage were improved obviously compared with that of the physiological saline group.Meanwhile,the value of MDA in the vitamin E group was greatly decreased and activity of SOD was notably increased compared with the sport group and the physiological saline group,but still worse than those of the control group.Conclusions Supplying of vitamin E could decrease the content of MDA in SR of skeletal muscle,increase the activity of SOD,then further relieve the effect of free radical on athletic injury.
