Objective To evaluate the correlation of the single nucleotide polymorphisms (SNPs) in CDH13 with non-small cell lung cancer (NSCLC) . Methods 115 patients with NSCLC and 110 healthy controls were included in present study. Two SNPs (rs11646213 and rs7195409) in CDH13 were genotyped using TaqMan method. The association of these two SNPs with NSCLC was calculated and assessed. Results The genotypic and allelic frequencies of rs11646213 showed significant difference between NSCLC patients and the control group (P<0.05), (OR=0.464, 95% CI:0.273~0.789) . The genotypic and allelic frequencies of rs7195409 showed significant difference between the stage I+II and stage III+IV groups (P<0.05), (OR=0.491, 95% CI:0.243~0.991) . Conclusions The rs16146213 has a strong association with NSCLC and G allelic showed a protective effect. The rs7195409 has a strong association between stage I+II and III+IV in NSCLC, and G allele may play a protective role in the development of NSCLC.

Objective To explore the potential association of HLA-A alleles and genetic susceptibility with systemic lupus erythematosus (SLE). Methods Polymerase chain reaction-sequence specific primer (PCR-SSP) was used to analyze the distribution of HLA-A alleles among 106 patients with systemic lupus erythematosus and 122 healthy persons. Results Nineteen out of twenty-four kinds of HLA-A alleles were found from the specimens, including 18 kinds in SLE specimens, and 15 kinds in control specimens. Among them, HLA-A*11 allele was positively associated with SLE (RR = 2.4380, EF = 0.1502, ?2 = 12.2440, P = 0.0005, Pc = 0.0095). For A*01 and A*24, although the P values were less than 0.05, the Pc values were more than 0.05 (0.9462 or 0.2356, respectively). Conclusions The results indicate that HLA-A*11 may be the susceptible allele or may be closely linked with the susceptible genes in Chinese SLE patients.

Objective To discuss the association of allele polymorphisms SNP-rs1799724(C>T)in the TNF-αand SNP-rs11559013(G>A)in the ALCAM with HCV chronic infection in Han population in Yunnan province. Methods 434 HCV chronic infectious patients and 444 healthy individuals of Han Chinese population in Yunnan province were recruited.

Objective: To compare the effect of scalp acupuncture and scalp acupuncture plus acupuncture exercise therapy (AET) on walking ability in children with spastic cerebral palsy (CP). Methods: A total of 60 spastic CP children with gross motor function classification system (GMFCS) grades Ⅰ-Ⅲ were divided into a control group and an observation group by the random number table method, with 30 cases in each group. Both groups were treated with the same conventional rehabilitation and scalp acupuncture therapy for CP. The control group received conventional rehabilitation first and then scalp acupuncture. The observation group received AET, which was to receive the conventional rehabilitation and scalp acupuncture simultaneously. Before and after treatment, the clinical efficacy was evaluated by the modified Ashworth scale (MAS) score, scores of dimensions D and E of the gross motor function measure (GMFM) scale, walking speed, and walking distance. Results: During treatment, there were 2 dropouts in the observation group. After 3 courses of treatment, the MAS scores in both the control group and observation group decreased compared with the same group before treatment (P<0.05), and the scores of dimensions D and E of the GMFM, walking speed, and walking distance were increased (P<0.05); the between-group comparison showed that the MAS score in the observation group was lower than that in the control group (P<0.05), and the scores of dimensions D and E of the GMFM, walking speed, and walking distance in the observation group were higher or longer than those in the control group (P<0.05). Conclusion: W ith the same treatments, scalp acupuncture combined with AET is superior to the conventional scalp acupuncture method in reducing lower-limb muscle tone, improving standing balance ability, and walking stability in children with spastic CP.

PURPOSE: Fanconi anemia complementation group F (FANCF) is a key factor to maintaining the function of Fanconi anaemia/BRCA (FA/BRCA) pathway, a DNA-damage response pathway. However, the functional role of FANCF in breast cancer has not been elucidated. In the present study, we evaluated the chemosensitization effect of FANCF in breast cancer cells. METHODS: We performed specific knockdown of the endogenous FANCF in breast cancer cells by transfecting the cells with an FANCF short hairpin RNA (shRNA) vector. Cell viability was measured with a Cell Counting Kit-8, and DNA damage was assessed with the alkaline comet assay. The apoptosis, cell cycle, and drug accumulation were measured by flow cytometric analysis. Protein expression levels were determined by Western blot analysis, using specific antibodies. RESULTS: The analyses of two breast cancer cell lines (MCF-7 and MDA-MB-435S) demonstrated that the FANCF shRNA could effectively block the FA/BRCA pathway through the inhibition of Fanconi anemia complementation group D2 ubiquitination. Moreover, FANCF silencing potentiated the sensitivity of cells to mitomycin C (MMC), where combined FANCF shRNA/MMC treatment inhibited cell proliferation, induced S-phase arrest, apoptosis, and DNA fragmentation, and reduced the mitochondrial membrane potential, compared with MMC treatment alone. CONCLUSION: Taken together, this study demonstrates that the inhibition of FANCF by its shRNA leads to a synergistic enhancement of MMC cytotoxicity in breast cancer cells. These results suggest that the inhibition of the FA/BRCA pathway is a useful adjunct to cytotoxic chemotherapy for the treatment of breast cancer.

OBJECTIVETo assess the association of single nucleotide polymorphisms (SNPs) of the low molecular weight polypeptide (LMP) gene with chronic hepatitis C virus (HCV) infection among ethnic Han population from Yunnan.

METHODSA total of 427 patients with chronic HCV infection and 412 healthy controls were recruited. SNPs rs1351383, rs17587 and rs2127675 from the promoter region of the LMP2 gene and rs2071543 from the promoter region of the LPM7 gene were genotyped using a TaqMan probe. The haplotypes were constructed. Frequencies of various alleles, genotypes and haplotypes of the selected SNPs were calculated, and their association with chronic HCV infection was analyzed.

RESULTSThe frequencies of rs1351383 and rs2127675 alleles of the LMP2 gene, as well as the A-G-A and C-G-G haplotypes of the rs1351383/rs17587/rs2127675 loci, had differed significantly between the two groups (P<0.05).

CONCLUSIONThe C allele of the rs1351383 locus and G allele of the rs2217675 locus of the LMP2 gene may be susceptible factors for chronic HCV infection among ethnic Han people from Yunnan. The A-G-A haplotype of the rs1351383/rs17587/rs2127675 loci may confer a protective effect, while the C-G-G haplotype may be a susceptible factor for chronic HCV infection in this population.

OBJECTIVE:To investigate the effects of tirofiban combined with atorvastation before PCI on the miRNA expres-sion of peripheral blood and vascular endothelial function in acute myocardial infarction(AMI)patients. METHODS:A total of 80 patients with AMI selected from our hospital as reaserch objects during Jan. 2015-Jun. 2016 were divided into control group and ob-servation group according to random number table,with 40 cases in each group. Both groups received anticoagulant therapy. Con-trol group was given Aspirin enteric-coated tablets 300 mg+Clopidogrel sulfate tablets 75 mg+ Atorvastatin calcium tablets 20 mg orally 30 min before PCI. Observation group was additionally given Tirofiban hydrochloride for injection with initial dose of 0.5 mg+0.9％ Sodium chloride injection 100 mL,iv,then adjusted to pump injection of 0.4 μg/(kg·min),30 min later adjusted to pump injection of 0.1 μg/(kg·min),for consecutive 24 h. The levels of peripheral miRNA (miRNA-1,miRNA-133a,miR-NA-208b,miRNA-499),the levels of brachial artery diameter and vascular endothelial function indexes(vWF,ET-1,NO)were observed in 2 groups before medication and after PCI,and the occurrence of ADR was recorded. RESULTS:Before treatment, there was no statistical significance in above indexes between 2 groups(P>0.05). After treatment,miRNA expression,the levels of vWF and ET-1 were decreased significantly in 2 groups,and observation group was significantly lower than control group,with statistical significance (P<0.05). The brachial artery diameter and NO levels of 2 groups were increased significantly,and observation group was significantly greater or higher than con-trol group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLU-SIONS:For AMI,tirofiban combined with atorvastation before PCI can reduce miRNA expression,increase brachial artery diame-ter and protect vascular endothelial function with good safety.

Objective:To retrospectively analyze the impact of adjuvant iodine-125( 125I)brachytherapy on postoperative recurrence and survival for patients with hepatocellular carcinoma (HCC) treated with partial hepatectomy with narrow resection margins. Methods:The data of 72 HCC patients who underwent partial hepatectomy with narrow resection margins from January 2011 to June 2015 at Weihai Municipal Hospital were analyzed retrospectively. The patients were divided into the adjuvant 125I brachytherapy group ( 125I group) ( n=36) and the control group ( n=36). The data of the two groups of patients were compared to study the factors influencing long-term survival outcomes and recurrence. Results:The follow-up time was (45.0±18.4) months. There were no deaths relating to 125I brachytherapy. The median recurrent free survival (RFS) was significantly longer in the 125I group than the control group (41.0 months vs 21.5 months, P<0.05). The 1-, 3- and 5-year RFS rates of the 125I group and the control group were 94.4%, 58.3%, 41.6% versus 86.1%, 33.3%, 25.0%, respectively ( P<0.05). The 1-, 3- and 5-year overall survival (OS) rates of the 125I group versus the control group were 97.2%, 69.4%, 52.8% versus 94.4%, 52.8%, 27.8%, respectively ( P<0.05). On multivariate analysis, 125I implantation was an independent factor affecting RFS and OS ( HR=2.112, 95% CI: 1.155-3.860, P<0.05; HR=2.492, 95% CI: 1.272-4.693, P<0.05). Conclusion:Adjuvant 125I brachytherapy was safe and effective for HCC patients with narrow resection margins after hepatectomy. It obviously reduced the tumor recurrence rate and prolonged the long-term RFS and OS.

OBJECTIVETo assess the association of four single nucleotide polymorphisms (SNPs) (rs12190359C>T, rs562047C>G, rs1008438G>T, and rs1043618G>C) of HSPA1A gene with the development of cervical cancer among ethnic Han Chinese from Yunnan.

METHODSOne hundred and thirty patients with CIN III, 444 patients with cervical cancer, and 548 healthy individuals were recruited, and the genotypes of the above SNPs were determined with a Taqman assay. Haplotypes were constructed, and their association with the development of cervical cancer was analyzed.

RESULTSThe frequencies of G and T alleles of rs1008438G>T were significant different between the CIN III and control groups, as well as between the cancer and control groups (P=0.022 and P=0.030, respectively).
