Objective:To evaluate the curative effects of patient controlled epidural analgesia(PCEA)for symptomatic lumbar disc herniation.Methods:Lumbar disc herniation cases(n=98)were divided into two groups.The epidural drugs injection group(DEDI group,n=54)underwent the epidural drugs injection 4 times as one treatment course.The patient controlled epidural analgesia group(PCEA group,n=44)underwent the same treatment,but the first epidural drugs injection was followed by PCEA for 7 days.Evaluate the curative effects and the side effects.Results:VAS scores in both groups decreased significantly on the eighth day and at the end of the treatment,being 4.41?0.62 and 1.30?0.77 in the PCEA group and 5.09?0.88 and 1.65?0.97 in the DEDI group(P0.05).No significant side effect was found during the treatment.Conclusion:PCEA is an effective method of lumbar disc herniation,and it relieves the symptoms and signs more quickly in the early treatment compared with the DEDI.

Objective To observe clinical effect of treating bronchial asthma in the acute attack with xiaoqinglong decoction combined with western medicine. Methods 50 patients with bronchial asthma were randomly divided into two groups. The control group was treated with theophylline sustained release tablets, 0.1 g～0.2 g for each time, twice a day,salbutamol sulfate (inhaled), 200 μg (2 spray) for each time, twice a day, beclomethasone dipropionate aerosol (inhaled),100 μg (2 spray) for each time, twice a day, antibiotics, oxygen inhalation when necessary, infusion, and correcting water-electrolyte and acid-base imbalance if necessary. Based on the control group, the treatment group was treated with Xiaoqinglong decoction for continuous 3 courses, once a day, 7 days as a course. The clinical effect and adverse reaction were observed between control group and treatment group after the treatment. Results The total effective rate of the treatment group and the control group was 84.6% and 66.7% respectively. The clinical effect in the treatment group was significantly higher than that of the control group (χ2=2.762, P＜0.05). Conclusion Xiaoqinglong decoction combined with western medicine has better effects bronchial asthma in the acute attack than western medicine.

Objective To evaluate the role of fibroblast growth faetor-2 (FGF-2) in neuropathic pain (NP) in rats.Methods One hundred male Sprague-Dawley rats,aged 7 weeks,weighing 200-250 g,were randomly divided into 4 groups (n=25 each): sham operation group (group S),group NP,phosphate buffer solution (PBS) group and FGF-2 antibody group (group Ab).FGF-2 antibody 18 μg (40 μl) was injected intrathecally at 1,6,9,13,16 and 20 days after operation in group Ab,while the equal volume of PBS was injected intrathecally in group PBS.Spinal nerve injury was produced by exposing the sciatic nerve and its branches and ligation and transection of tibial nerve and common fibular nerve.Pain behavior was assessed at 1 day before operation and at 1,4,7,14 and 21 days after operation.The paw withdrawal mechanical threshold (PWMT) was measured.The animals were then sacrificed and the lumbar segment (L4-6) of the spinal cord was obtained for determination of the contents of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the spinal cord.Results Compared with group S,the PWMT was significantly decreased and the contents of TNF-α and IL-6 in the spinal cord was significantly increased in groups NP,PBS and Ab (P ＜ 0.05).The PWMT was significantly higher and the contents of TNF-α and IL-6 in the spinal cord were significantly lower in group Ab than in groups NP and PBS (P ＜ 0.05).Conclusion FGF-2 is involved in the occurrence and development of NP and induction of the inflammatory response in the rat spinal cord in involved in the mechanism.

Objective:To investigate the role of reactive oxygen species (ROS) in the apoptosis of human hepatocellular carcinoma HepG_2 cells induced by PIG11 protein overexpression. Methods:The fluorescent probe 2', 7'-dichlorofluorescin diacetate (DCFH-DA) was used to label the intracellular ROS in pLXSN-PIG11-HepG_2 cells,pLXSN-HepG_2 cells and HepG_2 cells.The intracellular fluorescence intensity was detected by using the flow cytometry (FCM). The apoptotic ratio of HepG_2 was determined by FCM after elimination of intracellular ROS with 10 mmol/L N-acetylcystine (NAC). Results:The intracellular content of ROS in pLXSN-PIG11-HepG_2 cells was significantly higher than that in pLXSN-HepG_2 cells[(15.60±0.92) vs (4.90±0.70), P<0.01)]. The apoptotic ratio of pLXSN-PIG11-HepG_2 cells was significantly decreased by pretreatment with 10 mmol/L NAC (P<0.01). Conclusion:The apoptosis-inducing effect of PIG11 over-expression is related with elevation of intracellular ROS levels.
