OBJECTIVETo explore the mechanism of polypeptide extract from scorpion venom (PESV) on inhibiting angiogenesis.
METHODSThe H22 hepatoma tumor model was established by subcutaneously implanting H22 hepatoma cells into mice. The tumor-bearing mice were randomly divided into 4 groups, i.e., the control group, the high dose PESV group, the low dose PESV group, and the 5-fluorouracil (5-Fu) group, 10 mice in each group. The intervention was lasted for 14 days. The growth curve of the tumor volume was drawn and the inhibition rate calculated. Pathological changes of the tumors were observed by HE staining. The microvessel density (MVD) was detected using SP method. The protein expression levels of phosphatidylinositol 3-kinase (P13K), phosphoprotein kinase B (P-Akt), hypoxia-inducible factor-1 alpha (HIF-1 )alpha, and vascular endothelial growth factor-A (VEGF-A) were detected by immunohistochemical assay and Western blot.
RESULTSThe tumor inhibitory rate was 64.8%, 43.7%, and 32.4% in the 5-Fu group, the high dose PESV group, and the low dose PESV group. Compared with the control group, the protein expression of PI3K, P-Akt, HIF-1alpha, and VEGF-A were obviously inhibited by PESV and 5-Fu (P <0. 05,P <0. 01). The MVD also decreased in the high and low dose PESV groups (P < 0.05).
CONCLUSIONSPESV could inhibit the angiogenesis of H22 hepatoma. The mechanisms might be associated with suppressing the expression of PI3K, P-Akt, HIF-1 alpha, and VEGF-A.

OBJECTIVETo investigate the effect and mechanism of Zuoguiyin (ZGY, a Chinese medical remedy for regulating qi and nourishing yin) on expression of ovarian follicle-stimulating hormone receptor (FSHR) in rats during peri-menopausal period (PMP).
METHODSPMP rats were administered with low (13.78 g/kg), middle (20.67 g/kg) and high (31.00 g/kg) dose ZGY respectively by gastrogavage for eight weeks. FSHR mRNA and protein expressions were detected by RT-PCR and immunohistochemistry respectively. Besides, granulosa cells, collected from pregnant mare serum treated nonage rats, were incubated, and the level of FSHR mRNA expression in the cultured cells were detected after various disposals.
RESULTS(1) Ovarian levels of FSHR mRNA and protein expressions in PMP rats were significantly lower than those in young rats (P<0.01), but were up-regulated significantly by ZGY treatment (P<0.01). (2) As compared with the control, FSHR mRNA expression increased in cultured granulosa cells after treated by ZGY extract; the increasing effect of ZGY was enhanced by combined treatment with Forskolin and attenuated by Genistein (a tyrosine protein kinase inhibitor).
CONCLUSIONZGY could improve the ovarian functions during PMP by up-regulating the expression of FSHR and raise the ovarian responsibility to FSH, which may be possibly realized by activating cAMP-protein kinase and tyrosine protein kinase signal pathway.

UNLABELLEDOBJECTIVE To study the in vitro effect and mechanism of Ginkgo biloba Extract 50 (GBE50) for inhibiting beta-amyloid (Abeta)-induced oxidative stress in rats' hippocampal neurons.
METHODSThe primary hippocampal neurons were cultured in vitro and divided into 4 groups, i. e. the normal control group (Ctrl), the Abeta group, the propanediol control group (PDO), and the six GBE50 concentrations groups (5, 10, 25, 50, 100, and 200 microg/mL). Excepted the Ctrl group, neurons were induced to oxidative stress by 20 gmolLAbeta25-35. The MTT and fluorescent probes labeling were used to observe the effect of GBE50 with different concentrations on the cell viability and the generation of intracellular reactive oxygen species (ROS) in neurons. Furthermore, Western blot was used to detect the cytoplasmic/total cytochrome C (Cyto C) ratio and total intracytoplasmal Cyto C, and the effect of the expression of oxidative stress-related protein Cyto C and activated Caspase-3 in three GBE50 concentrations groups (25, 50, and 100 microg/mL).
RESULTSCompared with the Ctrl group, the cell vitality was obviously lowered and intracellular ROS generation significantly increased after induction of 20 micromol/L Abeta25-35 (both P < 0.05). Compared with the Abeta group, the cell vitality was evidently improved after treated with different GBE50 doses. Except for 10 microg/mL, the cell vitality could be obviously elevated along with increased drug concentrations (P < 0.05). Meanwhile, the intracellular ROS generation decreased significantly in each GBE50 dose groups (P < 0.05). Abeta could increase the cytoplasmic/total Cyto C ratio and enhance the activated Caspase-3 expression significantly (P < 0.05). Compared with the Abeta group, among the three concentrations of GBE50, the Cyto C ratio was obviously lowered in the 100 microg/mL GBE50 group (P < 0.05), and the expression of activated Caspase-3 significantly decreased in 50 microg/mL and 100 microg/mL GBE50 groups (P < 0.05).
CONCLUSIONS20 micromol/L Abeta25-35 could induce the generation of intracellular ROS in hippocampal neurons. GBE50 could inhibit Abeta induced intracellular oxidative stress of neurons through lowering the cytoplasmic/total Cyto C ratio and inhibiting the activation of apoptosis protein Caspase-3 expression.

Objective To investigate the clinical effect of pulmonary rehabilitation therapy including respiratory exercise and vibration expectoration on patients with pulmonary infection after abdominal surgery.Methods A retrospective case control study was conducted.Seventy-six patients with pulmonary infection after abdominal surgery admitted to the First Affiliated Hospital of Hunan Normal University from September 2015 to September 2016 were enrolled.According to whether accept the pulmonary rehabilitation therapy or not,the patients were divided into two groups.In the control group (n =35),the convemional expectoration method was adopted.The patients in pulmonary rehabilitation group (n =41) received both methods of the control group and pulmonary rehabilitation treatment,including respiratory exercise (effective cough,lip reduction breathing),respiratory exercise device (respiratory exerciser tri-ball),and vibrated expectoration.The 24-hour sputum volume,degree of comfort,inflammatory and pulmonary function parameters,and recovery situation were recorded in the two groups.Results ① There were no significant differences in the parameters of inflammation and pulmonary function before treatment between the two groups.After treatment,the white blood cell (WBC) and C-reactive protein (CRP) in both groups were significantly decreased,and the forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) were significantly increased.The above changes in pulmonary rehabilitation group were more significant than those of the control group [WBC (× 109/L):11.12 ± 2.88 vs.13.42 ± 2.62 at 3 days,8.22 ± 1.48 vs.9.27 ± 1.92 at 5 days;CRP (mg/L):13.47 ± 4.77vs.16.03±4.94 at 3 days,9.69±1.56 vs.11.77±1.41 at 5 days;FEV1 (L):2.48±0.14 vs.2.29±0.16 at 3 days,FEV1/FVC:0.78±0.04 vs.0.75±0.04 at 3 days;all P < 0.05].② The 24-hour sputum volume within 3 days of pulmonary rehabilitation group were significantly higher than that of the control group (mL:30.51 ± 4.15 vs.18.30 ± 3.64at 1 day,31.08±3.22 vs.20.37±3.20 at 2 days,29.03±2.55 vs.19.03±2.51 at 3 days,all P < 0.01].③ In the pulmonary rehabilitation group,the recovery time of pulmonary infection symptoms (days:5.44 ± 1.45 vs.6.20 ± 1.55),the days of antibiotic use (days:12.61 ± 3.15 vs.15.03 ± 3.78),the time of getting out of the bed (days:4.05 ± 0.74vs.4.51±0.89),and the hospital days (days:19.95±3.90 vs.22.00±4.42) were significantly shorter than those of the control group (all P < 0.05),and the degree of comfort was significantly better than that of the control group (comfort score:2.71 ±0.90 vs.2.14±0.91,P < 0.01).Conclusion The application of pulmonary rehabilitation including respiratory exercise and vibration expectoration in abdominal surgery patients with pulmonary infection can promote recovery,and it has a good clinical and practical application value.
