OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.

METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.

RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.

CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.

Objective This study aimed to explore the epidemiological characteristics and related factors of overweight and obesity in Tianjin adults. Methods With multi-stage randomized cluster sampling, 19 271 people aged 18 years and over were selected from both urban and rural areas of six geographical regions of Tianjin in 2006, using a cross-sectional methodology. Data from these residents was collected, using a questionnaire by face-to-face interview conducted by trained interviewers. Demographic, anthropometric data were collected in all participants. Data was analyzed with SPSS 13.0 software. For diagnosis of overweight and obesity, we adopted the standard of overweight and obesity recommended for Chinese adults. Age, gender and area distribution of overweight and obesity in the population of Tianjin were described, and the related factors were analyzed. Results Prevalence of overweight and obesity in adults from Tianjin were 32.8%(95%CI: 32.1%-33.5%) and 11.7% (95% CI: 11.2%-12.2%), with the standardized rates as 33.1% and 12.2%, respectively. Those figures were higher than the national average levels. The prevalence rates of overweight and obesity were increasing with age. The overweight rate in 50-59 year olds and the obesity rate in 60-69 year olds reached their peak values. The prevalence rate of obesity was higher in rural (13.5%,with 95%CI: 12.8%-14.2%) than in the urban areas (11.1%,with 95%CI: 10.4%-11.7%) and in females (12.6%,95%CI: 11.9%-13.2%) than in males (10.9%,95%CI: 10.3%-11.5%). Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Tianjin were statistically associated with age, gender, educational level, smoking, alcohol consumption and exercises. Conclusion As the urbanization progressing, the prevalence of overweight and obesity was much higher in the population of Tianjin city. Many factors were related to adults overweight and obesity. An active community-based public health intervention should be taken.

Objective To survey the prevalence of tendency on tendency of personality disorder among college students.Methods By means of stratified cluster sampling,498 students from 6 colleges in Shijiazhuang city and 204 students from 3 colleges in Beijing were studied through 'personality diagnostic questionnaire- revised UPDI'.Results The incidence rates on dependent personality (2.81%),histrionic personality (2.41% ) and borderline personality (2.21% ) were higher than obsessive- compulsive personality (0.40%) and schizoid personality (0.60%).The prevalence of personality disorder tendency was related to sex,major and years in college,blood type as well as their origins(from urban or rural).The overall incidence of personality disorder was 28.31% while the incidence rates of personality deviation and serious personality disorder tendency were 17.07% and 11.24% respectively.The incidence in males was higher than that in females.There appeared differences in dissociative personality,avoidant personality,paranoid personality,obsessive-compulsive personality,histrionic personality and narcissistic personality on people with different blood types.The scores of the city students were higher than that of the students from the rural areas regarding paranoid personality,dependent personality and narcissistic personality.Differences were also noticed between freshmen and students from other levels in the incidence rates on the tendency of avoidant personality disorder.Conclusion There were different incidence rates on the tendency of personality disorder among college students that related to sex,level in college and the origins where they were from(urban or rural).

Background Choroidal melanoma(CM)is a common form of primary ocular cancer in adults.It is reported that indomethacin has inhibitory effect on many tumor in vitro and in vivo,but whether it can inhibit the growth of CM has not been published. Objective This study was to investigate the anti-tumor activity of indomethacin on the growth of human CM OCM-1 cell xenografts in nude mice. Methods OCM-1 cells were subcutaneously implanted on 24 SPF female BALB/C.nu/nu nude mice to establish ectopic models of human CM.The nude mice with the tumor 5 mm were randomly divided into 4 groups:untreated group,normal saline solution(NS) group,indomethacin 1 ms/kg group,indomethacin 2 ms/kg group.The 1 mS/kg or 2 ms/kg indomethacin was intraperitoneally injected for 14 consecutive days in indomethacin 1 ms/kg group and indomethacin 2 me/kg group respectively.and 0.2 ml of 2%NS-DMSO was used at a same way in the NS group.No any agent was used as the untreated group.The volume and weight of implanted tumor as well as inhibitory rates of indomethaein on tumor were calculated.The expression of ki67 and survivin proteins were measured with immunohistochemistry,and the expression of survivin mRNA in CM was assessed by RT-PCR. ResuIts The tumor of indomethacin treatment group was reduced in volume and weight with a significant difference between treatment group and control group as well as indomethacin 1 ms/ks group and indomethacin 2 ms/kg group(P＜0.05).The inhibitory rate of indomethacin 1 ms/kg and 2 ms/kg for tumor was 22.86%,48.00%respectively.The prolifiration index (PI)of ki67 in these 4 groups were (76.73±3.34)%,(73.30±2.95)%,(55.97±2.24)%,(32.87±2.91)%respectively,and significant difference was found in PI between indomethacin 2 mg/kg group and untreated group or NS group(P＜0.05),but there was not significant difference between indomethacin 1 mg/kg and 2 ms/kg group(P＞0.05).Compared with the control group,the indomethacin treatment groups showed the decreased expression of survivin protein and mRNA,and significant difference was found between indomethaein 2 ms/kg group and untreated group or NS group(P＜0.05),however,no significant difference was found between indomethacin 1 mg/kg and 2 mg/kg group(P＞0.05). Conclusion Indomethacin inhibits the growth of CM in nude mice through inhibiting the expression of survivin in the tumor and accelerating cell apoptosis and inhibiting tumor cell proliferation.

Polyamidoamine-polyethylene glycol (PAMAM-PEG) copolymers were synthesized using IPDI as coupling reagent by two-step method. The copolymers were characterized by IR spectrum and 1H NMR spectrum, and the PEG conjugating ratios of the copolymers were calculated equal to 10% and 30% separately. MTT assay indicated that after PEGylation a lower cytotoxicity of the copolymers could be found, and with increasing PEG conjugating ratio the cytotoxicity decreased obviously. Agarose gel retardation assay demonstrated that PAMAM-PEG copolymers could be combined with DNA and PAMAM-PEG/DNA complexes were prepared by self-assembly. DLS measurement showed that when N/P > or = 50, the particle size of copolymer/ gene complexes was in a range of 150-200 nm, and the zeta potential was in a range of 10-25 mV. In vitro gene transfection illustrated that when N/P < or = 50, the gene transfection efficiency of PAMAM-PEG copolymers was a little less than that of PAMAM-G5, but the transfection efficiency can be raised by increasing N/P ratio or transfection time. Considering both cytotoxicity and transfection efficiency aspects PAMAM-PEG-13 was more effect than PAMAM-PEG-39 in PEGylation.

LEDGF/p75 is a newly found cell cofactor, which plays an essential role in the integration of HIV-1 cDNA into host chromosomes. LEDGF/p75 tethers HIV integrase to chromatin, protects it from degradation, and strongly influences the genome-wide pattern of HIV integration. Depleting the protein from cells or over-expressing the integrase-binding domain of LEDGF/p75 blocks viral replication. The essential role of LEDGF/p75 in HIV-1 replication makes it a new target for anti-HIV-1 drug development. This article reviews the function of LEDGF/p75, LEDGF/p75-integrase interaction and LEDGF/p75 inhibitors.

OBJECTIVEThe present study was undertaken to design antisense oligodeoxynucleotides (AS-ODNs) of glial glutamate transporter-la (GLT-1a) and to evaluate the effectiveness of the designed AS-ODNs on the expression of GLT-1a.

METHODSFive sequences of GLT-1a AS-ODNs were designed according to the C terminus specific sequences of GLT-1a mRNA using antisense design software of IDT Com- pany. Western blot analysis was used to evaluate the inhibition effects of the five GLT-1a AS-ODNs on the expression of GLT-la.

RESULTSThe sequence of GLT-1a AS-ODNs with sequence of 5'-GGTTCTTCCTCAACACTGCA-3' could specifically inhibit the expression of GLT-1a in the hippocampal CA1 subfield of rats, while it had no effect on the expression of GLT-1b. This sequence showed similar inhibition on the expression of GLT-la in sham and ceftriaxone (Cef)-treated rats. It could also significantly inhibit the cerebral ischemic preconditioning (CIP)-induced up-regulation in the expression of GLT-1a. The magnitude of the inhibition in sham, Cef- or CIP-treated rats was similar by more than 60%.

CONCLUSIONFrom the designed five sequences of GLT-1a AS-ODNs, we obtained an effective sequence which can specifically inhibit the expression of GLT-1a.
