Objective To investigate neuroprotective mechanisms of vinpocetine by observing the effects of vinpocetine injection on the expressions of peroxisome proliferators-activated receptor γ(PPARγ),nuclear factor (NF)-κB p65,cyclooxygenase-2 (COX-2) in the ischemic cortex,and infarct volume after focal cerebral ischemia-reperfusion in rats.Methods A focal cerebral ischemia-reperfusion injury model was induced by suture method.The rats were randomly divided into a normal control,a cerebral ischemiareperfusion and a vinpocetine groups.They were also divided into either a day 7 subgroup or a day 14 subgroup (n =6 in each subgroup) according to the reperfusion time.Western blot was used to detect the expression levels of PPARγand NF-κB P65 in the ischemic cortex.Triphenyl tetrazolium staining was used to detect the volume of cerebral infarction.Results Western blot showed that at day 7 and 14 after cerebral ischemia-reperfusion,expression levels of PPARκ (all P＜0.001) and NF-κB p65 (all P＜0.001) in the cerebral ischemia-reperfusion group were significantly higher than those in the sham operation group,the expression levels of PPARκ (all P ＜0.05) in the vinpocetine group were significantly higher than those in the cerebral ischemia-reperfusion group,but the expression levels of NF-κB p65 (all P ＜0.05) were significantly lower than those in the cerebral ischemia-reperfusion group.Reverse transcription polymerase chain reaction showed that COX-2 mRNA expression levels were upregulated significantly at day 7 and 14 after cerebral ischemia-reperfusion compared with the sham operation group (all P ＜ 0.001),the expression levels of COX-2 mRNA in the vinpocetine group were significantly downregulated compared with the cerebral ischemia-reperfusion group (all P＜ 0.05).The infarct volumes at day 7 (134.308± 9.954 mm3vs.185.543 ± 9.100 mm3;q=10.659,P＜0.001) and at day 14 (137.865 ± 9.094 mm3vs.183.210±4.368 mm3;q=11.166,P＜0.001) in the vinpocetine group were significantly less than those in the cerebral ischemia-reperfusion group.Conclusions Vimpocetine significantly reduces infarct vohme after focal cerebral ischemia-reperfusion,its mechanism may be associated with upreguhtion of PPARγexpression and downreguhtion of the expressions of NF-κB p65 and COX-2.

objective:To investigate the cause,pathogenesis,diagnosis and treatment of Wernicke encephalopathy(WE) after total parenteral nutrition(TPN). Methods:A retro spective study was conducted on 20 cases of clinical data about WE after long period of TPN. Results:WE usually occurred in the 2th～3th week of TPN support.18 cases of WE were treated with vitamin B_(1) in time,their symptoms disappeared and survived.2 patients died with misdiagnosis. Conclusion:Vitamin B_(1) is the key point to prevent and treat WE after long period of TPN.

Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P

OBJECTIVETo study the protective effect of rosmarinic acid (Ros A) on the primary cardiomyocyte hypoxia/reoxygenation (H/R) injury.

METHODPrimary cardiomyocytes of rats were cultured in vitro to establish the H/R injury of cardiomyocytes and observe the changes in the cell viability and LDH leakage. The changes in ATP content and ROS in cardiomyocytes were measured by using chemiluminescence and fluorescent probe technique. The effects of rosmarinic acid on the apoptosis of cardiomyocytes, cleaved-caspase 3, Akt and p-Akt protein expression were further detected by flow cytometry and western blot analysis.

RESULTAccording to the experimental results, Ros A at doses of 25, 50, 100 mg x L(-1) could inhibit the decrease in H/R-induced cell viability, LDH leakage and excessive ROS generation, and maintain the ATP level in cells. Ros A at doses of 50, 100 mg x L(-1) could remarkably inhibit the H/R-induced cardiomyocyte apoptosis and down-regulate the expression of cleaved caspase-3. Moreover, Ros A at doses of 100 mg x L(-1) could significantly up-regulate the expression of p-Akt.

CONCLUSIONRos A has the significant effect in resisting the cardiomyocyte H/R injury, improve cardiomyocyte energy metabolism and reduce cell apoptosis, which is related to the activation of Akt pathway.

Objective To study the effect of infrasound on the changes of expression of NMDAR1 in hipp- ocampal cells.Methods Eighty-eight male Sprague-Dawley rats were randomized into eleven groups:control group,90 dB/1 d,7 d,14 d,21 d and 28 d infrasound exposed groups;130 dB/1 d,7 d,14 d,21 d and 28 d infra- sound exposed groups.All the animals in the test groups were put in an infrasound field with 8 Hz,90 dB or 130 dB for 2 hours daily.Immunohistochemistry methods were used to detect the changes of intracellular expression of NMDARI in hippocampal cells.Methods The expression of NMDAR1 in hippocampus after the rats were exposed to infrasound of 8 Hz,90 dB SPL showed a procedure from reducing on the 1st day to rising on the 7th and peaked on the 14th day,then to descending on 21st day and returning to the standard level on the 28th day.Exposure to infra- sound of 8 Hz,130 dB SPL induced opposite effects on the expression of NMDAR1 compared with 90 dB SPL,which showed a process of increasing,descending,reaching to the lowest,then ascending and returning to the normal.The lowest expression of NMDAR1 occurred on the 14th day in every observed hippocampal area.Conclusion 8 Hz, 90 dB/130 dB infrasound induced certain reversible reaction in the expression of NMDAR1 of hippoeampal cells in rats,which may disturb their learning and memory function.

OBJECTIVETo observe the therapeutic effect of modified Zhizhu pill (ZZP) in treating gastro-esophageal reflux disease (GERD) and to explore its mechanism.

METHODSSixty-three GERD patients were randomly divided into the treated group (n = 30) and the control group (n = 33). The treated group was treated with ZZP 100 ml, twice daily by orally taking half an hour before meal. The control group was treated with Ranitidine 0.15 g, twice daily and Cisapride 10 mg, three times a day by orally taking before meal. The therapeutic course for both groups was 8 weeks. The changes of symptom scoring, endoscopic examination, esophageal pressure, 24 hrs monitoring on pH and blood level of motilin in the two groups were recorded and compared.

RESULTSAfter treatment, the symptom scoring, esophageal pressure, 24 hrs monitoring on pH and blood motilin level were improved in both groups (P < 0.05), and the improvement in the treated group was more significant than that in the control group (P < 0.05).

CONCLUSIONZZP has good effect in treating GERD.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.

METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.

RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).

CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.
