OBJECTIVETo study the protective effect of puerarin on MPP(+) -induced SH-SY5Y cells by chaperone-mediated autophagy (CMA).

METHODThe Parkinson's disease cell model was established by injuring SH-SY5Y cells with 1 mmol x L(-1) MPP+. The CCK-8 staining was adopted to detect the effect the puerarin of different concentrations on the survival rate of MPP(+)-induced SH-SYSY cells. The autophagosome formation was observed under transmission electron microscope. The AO staining showed the changes in the lysosome activity. RT-PCR was used to detect the changes in Lamp2a and Hsc70 mRNA expressions. The western blotting was adopted to test the expressions of Lamp2a, Hsc70 and alpha-synuclein protein in cells.

RESULTWithin the concentration range of 12. 5-50.0 micromol x L(-1), the pretreatment with puerain for 30 minutes could protect the injury of MPP+ in SH-SY5Y cells, and showed a certain dose-effect relationship. The AO staining and electron microscope showed the effect of puerain within the concentration range of 12.5-50.0 micromol x L(-1) on 1 mmol x L(-1) MPP(+)-induced SH-SY5Y cells; autophagosomes emerged in cells, and increased along with the rise in the puerarin dose. The results of the flow cytometry revealed that 50.0 micromol x L(-1) of puerarin could protect against the increase of the ROS level in 1 mmol x L(-1) MPP(+) -induced SH-SY5Y cells and prevent the oxidative injury. The results of RT-PCR and western blotting indicated that puerain within the concentration range of 12.5-50.0 micromol x L(-1) alleviated the MPP(+)-induced SH-SY5Y cell injury, and inhibited the accumulation of alpha-synuclein proteins in MPP(+) -induced SH-SY5Y cells by up-regulating Hsc70, Lamp2a mRNA and protein level.

CONCLUSIONPuerarin could protect against the MPP(+) -induced cell injury, whose protective mechanism may be related to the chaperone-mediated autophagy pathway of interventional molecules.

To build a reversed phase ion-pair chromatography to determination content of Dencichine from Panax notoginseng. Using Tetrabutyl ammonium hydroxide ions by the combination of reagent and HPLC method without derivatization to test the content of dencichine directly. The optimum conditions of supersonic extraction were solid-to-liquid ratio 1: 20, Continuous ultrasonic extraction: twice, each time 15 minutes; 3,500 r · min⁻¹, then centrifuging 15 minutes. Dencichine in different age, place, part and the different Processing mode were examined. The method is simple with sound separation degree and stability, which can facilitate the determination of dencichine content directly and provide the basis in quality standard of raw material.

Objective To study the effect of octreotide on patients with postoperative acute adhesive small bowel obstruction. Method In this study, 87 patients with postoperative acute adhesive small bowel obstruction were divided into 2 groups: experimental group (46 patients) and control group (41 patients). Patients in the control group were treated with routine therapy, including gastrointestinal decompression, intravenous infusion, antibiotic and enema. Patients in the experimental group were treated with routine therapy plus somatostatin analogue (octreotide) 0.1 mg. ih q8 h. for 72 hour. The alleviation of abdominal symptom and sign and the possibility of surgical intervention are observed and compared.Results Compared to the control group, the obstruction in the experimental group alleviated significantly,the abdominal pain relieved, the amount of draining decreased, and the passage of gas was earlier.Conclusions Based on the routine therapy, the use of octreotide significantly relieves the symptoms of obstruction and shortens the course of conservative therapy.

The effects on frozen-thawed sperm survival rate of 16 different cryoprotective media containing different ratio of glycerol (0%, 2.5%, 5% and 7%) and sucrose (0,25,50 and 100 mmol/L) were compared. The results showed that glycerol-sucrose cryoprotective media had better effect on cryoprotection of spermatozoa than that of traditional glycerol protective medium, and appropriately increasing the concentration of sucrose and decreasing the concentration of glycerol could improve sperm motility, and especially benefit to preserve sperm linear motility at 12h postthawed. Using 5% glycerol combined with 50 mmol/L sucrose as cryoprotective medium, the sperm survival rate at 0, 6, 12h postthawed was 85.38%, 51.22%, 33.38%, respectively, the linear moving sperm survival rate was 83.74%, 33.33%, 18.38% respectively.

OBJECTIVETo evaluate the efficacy of lumbar posterolateral fusion versus circumferential fusion in the treatment of the lumbar disease.

METHODSSearched MEDLINE (January, 1966 to December, 2007), EMBASE (January, 1984 to December, 2007), Cochrane Central Register of Controlled Trial (4th Quarter 2007), The China Biological Medicine Database (1984 to December, 2007), and hand searched several related journals, such as Spine, European Spine Journal, The Journal of Bone and Joint Surgery, Chinese Journal of Surgery, Chinese Journal of Orthopaedics, Chinese Journal of Spine and Spinal Cord, and so on. Searched the reviews, the clinical results and some other related studies on the two fusion techniques, and the quality of included trials was evaluated. Data were extracted by two reviewers independently with a designed extraction form. RevMan 5.0.5.0 software was used for data analysis of the fusion rate, the complication rate, the re-operation rate, the operative blood loss, the clinical outcome, and the operation time.

RESULTSFour randomized clinical trials (RCTs) involving 437 patients were included. The results of Meta-analysis indicated that in the fusion rate [OR 0.47, 95%CI (0.24, 0.94), P = 0.030], the complication rate [OR 0.53, 95%CI (0.32, 0.87), P = 0.010], and the operative blood loss [weighted mean difference (WMD) = -349.95, 95%CI (-561.64, -138.26), P = 0.001], the circumferential fusion group was significantly higher than the posterolateral fusion group. And in the re-operation rate [OR 2.28, 95%CI (1.30, 3.98), P = 0.004] the posterolateral fusion group was significantly higher than the circumferential fusion group. There were no statistically significant differences in the clinical outcome [OR 1.04, 95%CI (0.64, 1.68), P = 0.870] and the operation time [WMD = -90.24, 95%CI (-190.20, 9.71), P = 0.080].

CONCLUSIONSTo compare with the posterolateral fusion, the circumferential fusion can increase the fusion rate and reduce the re-operation rate, but it can also increase the complication rate and the blood loss. More high quality large-scale randomized controlled trials are required.
