Objective To explore the inhibitory effect of integrin-linked kinase antisense oligonucleotide(ILK-ASODN)on cell proliferation in human ovarian cancer cell line(HO8910).Methods We transfected ILK-ASODN into HO8910 to block ILK gene expression.measured the expression levels of integirn-linked kinase(ILK)mRNA by RT-PCR and ILK protein by western-blotting;the inhibiting effects of the transfection on HO8910 proliferation,the cell cycles,and cell apoptosis were assessed by water soluble tetrazolium-1(WST-1)and flow cytometry(FCM).Results After transfection of ILK-ASODN,the expression levels of ILK mRNA decreased significantly in groups D,E,F being 0.307±0.011,0.198±0.008,0,respectively,when compared with those of the two control groups of A and B(P＜0.05).The expression levels of ILK protein of the groups D,E and F decreased significantly also,being 26.3 ± 0.8,20.6±0.4 and O,respectively.HO8910 cell proliferation was inhibited significantly,and the rates of apoptosis of the groups D,E and F increased significantly,being 7.31%,8.84%and 11.27%respectively.The cell population increased in G0/G1 phase of the groups D,E and F,being 49.25%,56.28%and 67.61%respectively.significantly different in comparison with those of groups of A and B (P＜0.01).Conclusions Transfection of ILK-ASODN into human ovarian cancer line inhibited cancer cell proliferation significantly.

Objective To analyze the disposition characteristic of LGT fingerprints and the related fingerprints for advanced gastric carcinoma patients when the LGT fingerprints changing. Methods SELDI and CM10 protein chip was used to detect the serum protein fingerprints of 81 cased of advanced gastric cancer patients. After 1 year follow-up, all the patients were detected by SELDI again. According to the expression condition of LGT fingerprints, the patients were divided into 4 groups: A group(LGT changing from negative to positive) 25 cases, B group (LGT changing from positive to negative) 15 cases, C group (LGT fingerprints keeping negative) 29 cases and D group (LGT fingerprints keeping positive) 12 cases. The influencing factor should be rejected. And the remaining fingerprints were LGT fingerprints' subtypes and therelated fingerprints. The different proteomic fingerprints were analyzed by Biomarker Wizard 3.1 Software.Results After rejecting the influencing fingerprints, the up-regulation fingerprints in A group were 11473, 11821, 11664, 11409, 11552 and 11947 (M/Z), and no down-regulation fingerprints. In B group, 3264 was upregulation, and 6523, 11509, 11669, 11413, 11351 and 6483 were down-regulation. In C and D group, there was not statistically differential protein fingerprint. Conclusion M/Z up-regulating fingerprints including 11473, 11821, 11664, 11409, 11552 and 11947 can be regarded as the subtype of LGT when it changing from negative to positive; down-regulating including 11509, 11669, 11413 and 11351 can be regarded as the subtype of LGT when it changing from positive to negative; 3264 up-regulating and 6523 and 6483 downregulating can be regarded as the related fingerprints when LGT changing from positive to negative; and when LGT keeping negative or positive in patients with advanced gastric cancer, there was no differential protein fingerprints.

AIM:To establish HPLC method for the determination of amodiaquine in human plasma.METHODS: Amodiaquine and internal standard(hydroxychloroquine) were analyzed on C18 column(150 mm ×4.6 mm, 5 μm) with methanol: water:triethylamine: orthophosphoric acid (21:77.5:1:0.5 )as mobile phase at the flow rate of 1.0 mL · min-1The UV detector was set at 294 nm. RESULTS: The retention times of amodiaquine and internal standard were 5.82, 8.56 min, respectively. The calibration curve was linear in the range from 10 to 1 000 μg ·L- 1 ( r = 0.999 8, n = 9 ). The limit of quantitation was5 μg· L-1. The extraction recovery was between 75.5 % and 82.7 %, and the methodological recovery was between 97.0 % and 104.8 %. The intra-day and inter-day RSD were less than 6.0 % and 7.5 %, respectively. CONCLUSION: This HPLC method is simple, sensitive and suitable for pharmacokinetic study of amodiaquine.

Bone morphogenetic proteins (BMPs) are multi-functional growth factors,they are found not only inducer of new bone formation,but also have critical roles in cell growth,differentiation,migration,apoptosis,embryogenesis and organogenesis.Studies show that BMPs are closely related to tumorigenesis and metastasis,which have important practical values in tumour therapy.

OBJECTIVE:To establish a method for the determination of 9 residual organic solvents in blonanserin as methanol, alcohol,isopropyl alcohol,acetonitrile,dichloromethane,hexane,ethyl acetate,tetrahydrofuran and methylbenzene. METHODS:Headspace gas chromatography was adopted. The determination was performed on DB-624 capillary column using temperature pro-gramming. The inlet temperature was 150 ℃,and flame ionization detector was used with temperature of 250 ℃. High purity nitro-gen was used as carrier gas with flow rate of 2.8 mL/min. The split ratio was 1:1,and headspace sample size was 1 mL. Head-space heating temperature was 90 ℃,and equilibration time was 35 min.

OBJECTIVE: To investigate the epidemiological features in patients with allergic rhinitis (AR) in Yichang city, and put forward effective prevention and control measures. METHOD: Collecting the data of allergic rhinitis in city proper from 2010 to 2013, input the data into the database and used statistical analysis. RESULT: In recent years, the AR patients in this area increased year by year. The spring and the winter were the peak season of onset. The patients was constituted by young men. There was statistically significant difference between the age, the area,and the gender (P < 0.01). The history of allergy and the diseases related to the gender composition had statistical significance difference (P < 0.05). The allergens and the positive degree in gender, age structure had statistically significant difference (P < 0.01). CONCLUSION Need to conduct the healthy propaganda and education, optimizing the environment, change the bad habits, timely medical treatment, standard treatment.

OBJECTIVETo observe the changes of proximal femoral geometry after femoral neck fracture treated with THA, analyze the existent of differences and their manifestation.

METHODSAll patients of femoral neck fracture (FNF) and osteonecrosis of femoral head (ONFH) were treated with THA by the same operating team from January to December of 2014, including 22 patients with FNF (11 males and 11 females,with age from 44 to 83 years old (means 66.18 ± 11.47) and 23 patients with ONFH (12 males and 11 females, with age from 19 to 68 years old (means 51.91 ± 11.76). After THA, height of femorals, offsets, osteotomy position and adjusting modes were measured and the statistic analysis was done.

RESULTSAfter THA, all patients were measured. Decreased femoral height, offsets and lower osteotomy positions were found in patients with FNF than those with ONFH, and 3 kinds of adjustments because of lower-positional osteotomy were found.

CONCLUSIONAfter THA, lower-positional osteotomy and decreased femoral offsets may occur on patients with FNF. The adjustments caused by lower-positional osteotomy may lead to negative results.

OBJECTIVETo study the medium and long term effects of perfusion of bone marrow stromal stem cells through optional artery for the treatment of non-traumatic femoral head avascular necrosis.

METHODSFrom January 2000 to December 2004,62 cases(78 hips) with non-traumatic femoral head necrosis accepted optional artery marrow stromal stem cells infusion treatment and had complete follow-up data, including 43 hips of 35 males and 35 hips of 27 females with an average age of 36.3 years old (22 to 54). According to preoperative imaging data, 16 hips were ARCO I stage, 52 hips were II stage, 10 hips were III a stage. Harris score was 64.94 +/- 8.12 preoperatively. Postoperative Harris score at the last follow-up, imaging changes,DSA vascular changes were analysis.

RESULTSThe patients were followed up for 9 to 13 years (means 11 years). By the end of the follow-up, a total of 18 hips got artificial joint replacement, 10 hips of preoperative ARCO I, II period got artificial hip joint replacement, 8 hips of IIIa period got hip artificial joint replacement. Harris score was 71.21 +/- 0.19 at the end of the follow-up, it was obviously enhanced compared with preoperative. DSA showed blood vessels of supply the femoral head increased thickening.

CONCLUSIONPerfusion of bone marrow stromal stem cells through optional artery can effective treat non-traumatic femoral head necrosis of ARCO I, II period, it can make the femoral circumflex artery and its branches increased thickening.
