OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).
METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.
RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).
CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

AIM: To explore the nursing cooperation highlights of eight osteopetrosis patients underwent optic nerve decompression via transsphenoidal microsurgical approach instead of routine pathway, and to improve the quality of nursing cooperation. ·METHODS: We enrolled 8 cases ( left eye in 3 cases, right eye in 5 cases ) of osteopetrosis patients referred from the Eye Hospital of Wenzhou Medical University during February 2012 to November 2016. Patients received ophthalmic examinations including visual acuity and diagnostic imaging tests in pre-operation and post -operation. All eyes were performed surgical optic nerve decompression through endoscopic approach in assist of image guidance system. We retrospectively analyzed the clinical data and surgical cooperation procedure of these cases and summarized nursing cooperation experience. ·RESULTS:The operations of 8 patients were completed successfully without massive hemorrhage. Mean visual acuity improved from pre-operation (2. 5±2. 1) to post-operation (3. 4±1. 9). Cerebrospinal fluid leakage occurred in 1 patient and was instantly repaired during the operation. We performed the nursing strategy as postural drainage, condition monitoring and conscious assessment intra-and post-operation. ·CONCLUSION: It is the critical for this kind of surgery that both circulating nurse's high-skilled cooperation to the connection and operation of the navigation system, to treat with complication during the surgery, and scrub nurse's sufficient preparation of surgical instruments and consumables, proficient equipment delivery, meticulous management, use and maintenance of equipment.

Objective To examine expression of PTEN gene in ovarian cancer cisplatin-sensitive cell line OV2008 cells and cisplatin-resistant cell line C13K cells,and evaluate the effect of wild-type PTEN gene on reversing cisplatin-resistance of C13K cells and underlying mechanisms.Methods The expression of PTEN mRNA and protein in OV2008 and C13K cells were detected by semi-quantitative RT-PCR and western blot.Recombinant eukaryotic expression plasmid containing human wild-type PTEN gene was transfected into C13K cells by lipofectamine 2000.The expression of PTEN mRNA was monitored by RT- PCR and the expression of PTEN,protein kinase B(AKT),phospho-AKT(p-AKT)protein were analyzed by western blot in PTEN transfected and untransfected C13K cells.Proliferation and chemosensitivity of cells to cisplatin were measured by methyl thiazolyl tetrazolium(MTT),and cell apoptosis was detected by flow cytometry after treatment with cisplatin.Results(1)The expression of PTEN mRNA and protein(1.02 ?0.05,1.02?0.07)in OV2008 cells were significantly higher than those in C13K cells,which were 0.45 ?0.03 and 0.55?0.03 respectively(P

Objective To learn the effects of control measures,the screening situation and the epidemic situation of Schistosomiasis in Yongsheng county of Lijiang city of Yunnan province,and to provide a scientific basis for developing control strategies.Methods Annual surveillance data of Schistosomiasis of Yongsheng county from 2002 to 2010 were collected and analyzed by material retrospective method.Schistosomiasis screening situation,infection rate of people and cattle as well as snails area was statistically analyzed.Infection rate of people was from the screening results by indirect hemagglutination(IHA),and pathogenic examination of the positives(1 ∶ 10)was carried out through collection of eggs with nylon bag and hatching the stool.Infection rate of cattle was from etiology examination results by plastic cup pipe jacking method.Results From 2002 to 2010,257679 individuals were screened and 26540 cases (10.30%) were seropositive; with stool examination,451 (1.72%) were identified positive of 26233 persons; 603 (0.71%) were found positive of 85658 oxen.All of the positive detection rate of IHA method,the feces-positive detection rate in the population and the prevalence rate of oxen showed a declining trend(x2 =3615.53,785.68,434.50,all P< 0.05).The snails area was gradually reduced,the rate of snails environmental area was decline from 23.82% in 2004 to 1.98% in 2010.Conclusions The endemic situation of Schistosomiasis in Yongsheng county is controlled in the past eight years,but remains epidemic,and we will continue to strengthen monitoring,in order to achieve the goal of blocking the spread of Schistosomiasis.

Objective To study the correlation between level of nitric oxide/ nitricoxide synthase(NO/NOS) on placenta homogenate and ultra-structure changes of placenta in pregnancy lead exposure in rats.Methods Seventeen normal pregnant rats and 46 rats of exposured in lead which were divided into A,B,C groups were studied.The level of NO/NOS of placenta were measured by nitrate reductase and NOS kit.Placentas were randomly selected from each group to detect ultra-structure by electron-microscope.Results There were significant difference among A,B and control groups on level of NO/NOS(all P0.05).Compensation hyperplasy or minor injury were observed in lead exposure of stage groups.Lead exposure during whole gestation period,the lead level was maxmum,and decompensation were observed on placental construction.Conclusions There is a close correlations between level of lead,NO/NOS and pathological change of placental tissue,and both of them may play an important role in the pathogenesis of peripartum lead exposure.
