Objective To observe the effect of transcranial low frequency electrical stimulation on the contents of monoamines in ischemic area of rats with middle cerebral artery occlusion(MCAO).MethodsPermanent MCAO model of Wistar rat was established with silk thread enveloped with polyammoniacum.The ischemic areas received various intensity of transcranial low frequency electrical stimulation for 1 hour in rats underwent 1 hour of ischemia.Then the affected tissue was processed with fluorospectrophotometry to determine the contents of dopamine(DA),noradrenalin(NE) and 5-hydroxytryptamine(5-HT).ResultsCompared with the sham-operation group,the contents of DA,NE and 5-HT in ischemic area of MCAO model rats decreased obviously(all P<0.01),while all three monoamines investigated in the sham-operation group with transcranial low frequency electrical stimulation had no significant change.In the MCAO groups stimulating with lower(10 V) and middle(30 V) intensity transcranial low frequency electrical field,the contents of DA,NE and 5-HT in ischemic area had no significant increase.But in the MCAO group stimulating with high(50 V) intensity transcranial low frequency electrical field,the contents of DA,NE and 5-HT in ischemic area increased significantly(P<0.05).ConclusionSome degree of intensity transcranial low frequency electrical field stimulation can increase the contents of DA,NE and 5-HT in ischemic area of rats subjected to MCAO.

One hundred and forty six elderly patients with constipation undergoing colonoscopy during March 2012 and August 2013 were randomly assigned to trial and control groups.Seventy patients in trial group received Macrogol electrolytes powder combined with Chinese herb medicine Simo decoction for bowel preparation and 76 patients in control group received macrogol electrolytes powder only.The first defecation,times of defecation and tolerance of patients were compared between two groups.The quality of bowel preparation was evaluated by endoscopists with Boston Bowel Preparation Scale (BBPS).The first defecation time was shorter in trial group than that in control group (55.7 ± 27.9 vs.72.9 ± 34.8,P < 0.05).However,no statistical significance was found in the times of defecation and tolerance of patients between two groups.The mean BBPS score in trial groups was higher than that in control group (7.87 ± 1.08 vs.6.97 ± 0.96,P < 0.05).Chinese herb medicine Simo decoction combined with conventional method shows satisfactory result for bowel preparation in elderly patients with constipation undergoing colonoscopy.

Objective To discuss clinical effects and indications of minimally invasive tension band technique in treatment of transverse patella fractures.Methods Thirty-eight patients with transverse patella fracture (close or slightly polluted open ones) were treated with minimally invasive tension band technique from July 1997 to June 2005 in our department.Twenty-six were fixated with percutaneous Kirschner wire tension hand and 12 with percutaneous cannulated screw tension band.The reduction,movement range and function of the knee were analyzed.Results Surgeries went on uneventfully.All the cases were followed up from six months to 6.5 years (average,32 months).Fracture healing time lasted from 6 to 12 weeks,averaging 7.7 weeks.No such compli- cations as traumatic arthritis occurred.Reduction was excellent in 21 cases,good in 11 and fair in six,with the good-to-excellent rate being 84.2%.All the affected knee joints could move in normal range.The functional re- covery was assessed as excellent in 34 cases and good in four.Conclusions Internal fixation with minimally invasive tension band technique is good for treatment of transverse patella fractures.It is chiefly fit for close or slightly polluted open fractures with limited wound,and can also be used for the comminuted fractures if the bone fragments are no more than three and the fracture site is suitable.

OBJECTIVETo observe the impact of inducing the formation of the post-moxibustion sore on the efficacy of bronchial asthma treated with scarring moxibustion.
METHODSThree hundred and seventy-two cases diag nosed definitely as bronchial asthma at remission stage were randomly divided into a modified nursing group (248 cases) and a conventional nursing group (124 cases). The scarring moxibustion was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17) and Tiantu (CV 22) in either group. The direct moxibustion with moxa cone was adopted. In modified nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into an inverted triangle and compressed on the wound. After suppuration, the fester was not cleaned in each dressing change. Additionally, the patients were advised to have high-protein diets after moxibus tion till abscess dropped. In conventional nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into a round shape that could cover completely the moxa wound. After suppuration, in each dressing change, the wound was cleaned and sterilized. Additionally, the patients were advised to avoid any stimulating food after moxibustion till abscess dropped. The clinical efficacy, the change of C3 content in blood serum and the clinical symptom score were observed in two groups.
RESULTSThe total effective rate was 93.5% (232/248) in modified nursing group, which was better than 79.0% (98/124) in conventional nursing group (P < 0.01). C3 content increased apparently after treatment as compared with that before treatment in either group (both P < 0.01), but C3 level increased much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01). The clinical symptom score reduced apparently after treatment in either group (both P < 0.01), but that reduced much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01).
CONCLUSIONIn the treatment of bronchial asthma with scarring moxibustion, to induce the formation of the post-moxibustion sore achieves the better clinical efficacy as compared with conventional nursing.

OBJECTIVE This study was designed to evaluate the effect of berberine on CUMS induced depression animal model and investigated the underlying mechanisms.METHODS We estab-lished CUMS depressant rat model and treated CUMS rats with berberine.Sucrose preference,forced swim test(FST)and tail suspension test(TST)were used to measure behaviors change.We used Q-PCR and western blot to test the levels of cytokines in the hippocampus. RESULTS We found that CUMS rats displayed obvious depressive like behaviors,moreover,berberine treatment prevented depressive behaviors in CUMS rats accompanied with suppression of oxidative stress markers. Further experi-ments showed that berberine treatment up-regulated the expression of Keap1-Nrf2 antioxidant signaling pathway and its downstream neuroprotective factors. CONCLUSION Our present results suggested that treatment of berberine significantly ameliorated depressive behaviors in CUMS rats through enhancing of Keap1-Nrf2 antioxidant signaling pathways in hippocampus.

Objective: To select the telomerase positive cancer cell lines of gastrointestinal tract and to provide a convinced methodology for future telomerase study. Methods: Fifteen cancer cell lines (carcinoma of stomach 4, of liver 6, of pancreas 2, of colon 3) were cultured and telomerase activity were detected by TRAP-ELISA. The normal hepatic cells were taken as control. Results: Thirteen cell lines were telomerase positive in the 15 lines(86.7%). Conclusion: Most of gastrointestinal tract cancer lines express telomerase, indicating the detection of telomerase activity has clinical potential.

Objective: To study the effect of intracellular-free calcium and the expression of Fas and Fas L on the process of pancreatic carcinoma cell apoptosis. Methods: Apoptosis induced by 2 μmol/L arsenic trioxide in pancreatic cancer cell lines SW-1990 was investigated.Concentration of intracellular-free calcium ([Ca2+]i) was determined by Fura-2a fluorescein load technique. Fas and FasL were determined by flow cytometry. Results: Pancreatic cancer cells treated with 2 μmol/L arsenic trioxide presented apoptotic features: intact cell membrane, chromatin condensation, nucleic fragmentation and apoptotic body formation; agarose electrophoresis showed marked ladder; flow cytometery analysis showed a sub-G1 cell peak. In the process of pancreatic carcinoma cell apoptosis Fas and FasL and the [Ca2+]i were significantly higher than that in the control. Conclusion: The pancreatic cancer cell apoptosis induced by arsenic trioxide is related to Fas and FasL expression by the cancer cells and the [Ca2+]i increase in the cancer cells.
