Objective To investigate the association of the single nucleotide polymorphisms (SNPs)G→A (R219K) in the exon 6 of ATP-binding cassette transporter A1 (ABCA1) gene with sporadic Alzheimer's disease (SAD) in the Han Chinese population.Methods Genotypes were determined by PCR-restriction fragment length polymorphism (PCR-RFLP) in 168 SAD patients and 215 healthy controls. The association between the polymorphism and AD was estimated with the odds ratios (OR).Results The frequency of A allele in SAD cases was significantly lower than in controls (37.8 % vs 48.1%,x~2=8.204, P=0.004),and the frequency of AA genotype in SAD cases was also significantly lower than in control (14.3% vs 22.8%,x~2=8.230,P=0.016).Logistic regression analyses adjusted for age,gender and ApoEe4 status showed that the risk for AD was decreased in A allele (G/A+A/A genotypes,OR 0.57, 95% CI 0.36—0.91,P=0.019) or AA homozygote carriers (OR 0.40,95% CI 0.21—0.77,P= 0.006) compared with GG genotypes carriers.Conclusion Our data indicate a genetic association between polymorphism in exon 6 of ABCA1 gene and the risk of AD and reveal that AA genotype or A allele of ABCAI gene may have a protective effect on AD in the Han Chinese.

Objective: To investigate the expression of P16 protein in oral verrucous carcinoma (VC) and oral squamous cell carcinoma (SCC) and to reveal its role in the occurrence and development of VC . Methods: Using streptavidin/peroxidase(SP) immunohistochemical technique(IHC) the expression of P16 protein in 41 samples, including 8 of normal mucosa (NM),13 VC,10 well differentiated squamous cell carcinoma (wdSCC),10 poorly differentiated squamous cell carcinoma (pdSCC) was studied.The average intensity score (IS) of immunohistochemical staining of the samples was calculated. Results: Weakly positive of P16 protein was obsereved in the 8 cases of NM. Positive expression was found in 10 of the 13 VC cases,8 of the 10 wdSCC and 6 of the 10 pdSCC.The IS in NM,VC, wd SCC and pdSCC was 0.4375?0.0498,1.5846?0.2681,0.9900?0.1894 and 0.8800?0.2590 respectively.The mean intensity of P16 protein in VC was higher than in wdSCC and pdSCC(P

Objective: Our purpose was to study the predictive factors of interferon(IFN) therapeutic effectiveness. Methods:Genotypes of HCV, HCV RNA quantities, β2 microglobulin, 2′- 5′oligoadenylate synthetase, and peripheral blood lymohocyte subgroup were detected by using specific primer PCR assay, energy transference technique of signal primer, sheet chromatography, radioimmunoassay, and APAAP immunoenzyme bridge technique respectively in 20 blood samples of patients with chronic hepatitis C. Results:(1)The patients who had lower level of HCV RNA before treatment and had continuing decreased HCV RNA level after treatment had good response to IFN treatment in follow-up survey. (2)The patients with HCV-Ⅲ type had complete response much more than those with HCV-Ⅱ type (P＜0.05).(3)The patients with lower level of 2′- 5′oligoadenylate synthetase before treatment might have good response to IFN treatment. (4) There was no significant change in β2 microglobulin level before and after treatment and in different response groups before treatment.(5) The CD+3, CD+4, and CD+4/CD+8 in peripheral blood increased after treatment. The patients in complete response group had higher level CD+3, CD+4, and CD+4/CD+8 than those in part response and non-response groups, but there was no significance in statisitcs. Conclusion:The HCV RNA quantities, HCV genotypes, 2′- 5′oligoadenylate synthetase level before treatment were predictive factors of IFN therapeutic effectiveness. The changes of HCV RNA level in treatment and follow-up survey had important significance in therapeutic evaluation, β2 microglobulin level, and lymphocyte subgroup before treatment were not used as predictive factors for IFN therapeutic effectiveness.

This Meta-analysis systematically assessed the efficacy and safety of Shengmai Injection (SMI) combined with conventional treatment for acute myocardial infarction (AMI). Seven online databases were investigated, then randomized clinical trials (RCTs) of treatment effects of AMI patients, for which SMI was used in combination with conventional therapy compared with conventional therapy alone, were included. The literatures selection, data extraction, and quality assessment were in accordance with the Cochrane standards. Data analysis was carried out using RevMan software (V.5.3). RCTs (enrolling 1 258 patients) from 18 literatures published in Chinese journals were included in the systermatic review. The additional SMI could significantly reduce the risk of mortality, arrhythmia, cardiogenic shock, heart failure and improve left ventricular ejection fraction (LVEF), stroke volume (SV), vascular patency rate. The adverse effects of mild bleeding, palpitation, shortness of breath, fatigue could occur both in the control group and the treatment group. Thus, it was difficult to evaluate the safety of SMI due to the limited data and low-guality RCTs. Therefore, high-quality and adequate sample of RCTs with low risk of bias are required to demonstrate its true effects.

Objective:To observe the effect of acupoint massage plus acupoint sticking therapy for the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery.Methods:A total of 120 patients undergoing nasal endoscopic surgery were included,and all patients were under trachea intubation and general anesthesia.The patients were randomized into an observation group and a control group,with 60 patients in each group.Patients in the control group received conventional anesthesia resuscitation,while patients in the observation group received acupoint massage plus acupoint sticking therapy on the basis of conventional anesthesia resuscitation.Changes in the heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed at three time points including the end of the surgery (TO),the removal of the tracheal tube (T1) and 10 min after the removal of the tracheal tube (T2).The awakening and tube removal time,choking cough and restlessness,and adverse reactions (dizziness,nausea and vomiting) in 24 h post-surgery period were compared.Results:At T1 and T2,the comparisons of HR,SBP and DBP between the two groups showed statistical significance (all P＜0.05).Intra-group comparisons showed that the HR,SBP and DBP of the control group at T1 and T2 were significant different from those at TO (all P＜0.05).There were significant differences in the awakening time and tube removal time between the two groups (both P＜0.05).The incidences of choking cough and restlessness were 8.3％ and 3.3％ respectively in the observation group,versus 53.3％ and 30.0％ in the control group,and the between-group comparisons showed statistical significance (both P＜0.05).The incidences of dizziness,nausea and vomiting in 24 h post-surgery period were 3.3％,5.0％ and 0.0％ respectively in the observation group,versus 43.3％,33.3％ and 25.0％ in the control group,and the between-group comparisons showed statistical significance (all P＜0.05).Conclusion:Acupoint massage plus acupoint sticking therapy can effectively regulate the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery,and maintain a stable internal environment.

Based on avian leukosis virus ( ALV) p19 gene terminal nucleotide sequence, a 82 bp double-stranded DNA fragment was chemically synthesized and cloned into the expression vector pGEMEX-1. The sequencing result indicated th at the cloned fragment was a correct version of the one designed both in nucleot ide sequence and in its open reading frame. The recombinant was used to transfor m E.coli BL21 (DE3). The cloned fragment was expressed as a fused protein wi th T7 gene 10 leader peptide and was shown to be 34 kD in size on SDS-PAGE gel when induced with 1 mmol/L IPTG. The expression product was able to bind immunol ogically to rabbit anti-ALV serum in Western-blot assay and is being tested to differentiate exogenous from endogenous ALV.

To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

Objective To observe the clinical efficacy and adverse reactions of tigecycline in treatment of health-care-associated pneumonia (HAP ) caused by extensively drug-resistant Acinetobacter baumannii (XDRAB ). Methods Clinical data of patients who used tigecycline for the treatment of XDRAB HAP in intensive care units of a hospital from March 2013 to June 2014 were retrospectively analyzed.Results XDRAB isolated from 31 patients with HAP were all sensitive to tigecycline,the resistance rates to carbapenems and sulbactams (including cefopera-zone-sulbactam,SCF)were all 100%,17 cases (54.84%)were mixed infection.Combined use rates of tigecycline and SCF were 85.71 %(12/14)in respiratory intensive care unit(RICU)and 47.06%(8/17)in general intensive care unit(GICU).Of 31 patients,the cure rate,effective rate,bacterial clearance rate,and antimicrobial adverse reac-tion rate were 29.03%,45.16%,61 .29%,and 16.13% respectively,no serious adverse drug reactions occurred. In RICU group and GICU group,the cure rates were 42.86% and 17.65% respectively,effective rates were 71 .43% and 23.53% respectively,and bacterial clearance rates were 78.57 % and 47.06% respectively,difference in effective rate between two groups was significant (P <0.05).Among patients receiving combination of tigecycline and SCF as well as not receiving combined SCF,the cure rates were 35.00% and 18.18% respectively,effective rates were 60.00% and 18.18% respectively,and bacterial clearance rates were 65.00% and 54.55% respectively, difference in effective rate between two groups was significant (P <0.05).Conclusion Tigecycline has a good clini-cal efficacy and little adverse reaction in treating XDRAB HAP;tigecycline combined with SCF is a good choice.
