Objective To evaluate the impact of human papillomavirus(HPV)infection on the risk of HIV acquisition in the female group.Methods Searched PubMed,EMbase,Coehrane Library,CNKI,wanfang database and Chinese Biomedical Lit-erature Database etc for articles about HIV-acquisition in HPV infected female patients.The quality of the literature were e-valuated according to standards of inclusion and exclusion.Data was extracted and methodologically quality evaluated by two independent investigators.Meta-analysis was accomplished using RevMan4.2 software.Results 6 articles were included,all of them were randomized controlled trials,a total of 9 606 cases studied.HIV infection risk was doubled in women with any HPV infection(OR= 2.02,95% CI:1.48 ~ 2.77),demonstrating High-risk HPV-positive (OR= 2.50,95% CI:1.73 ~3.61)and low-risk HPV-positive (OR=2.10,95% CI:1.48~2.96)respectively.Funnel plot analysis revealed no signifi-cant publication bias on HPV genotypes.Conclusion The analysis of selected research suggests the risk of HIV infection was increased in HPV-positive women.HPV vaccine may have some preventive effect on HIV infection.

Objective To evaluate the effect of intrathecal ketamine on nitric oxide synthase (NOS)activity in the spinal dorsal horn via a rat model of sciatic constriction injury(SCI). Methods Thirty-six male SDrats weighing 160-180g were randomly divided into six groups(n = 6 in each group): group Ⅰ sham operation;group Ⅱ SCI; group Ⅲ-Ⅵ intrathecal ketamine + SCI. In group Ⅰ right sciatic nerve was exposed but noligature was placed around sciatic nerve. In group Ⅱ-Ⅵ four ligatures were placed around the right sciatic nerveand hed without obstructing the blood supply of the nerve. In group Ⅲ -Ⅵ ketamine 12. 5?g (group Ⅲ ),50?g(group Ⅳ ), 0?g (group Ⅴ ) or 300?g (group Ⅵ ) was given intrathecally 30 min before and 1,2 and 3 daysafer surgery. On the 7th and 14th day after operation thermal and mechanical hyperalgesia were measured with ice-cold water and von-Frey filaments. The animals were decapitated 14 days after SCI. The I_(4-6) lumbar spinal cordwas immediately removed and the spinal dorsal horn was dissected on ice and homogenized. The homogenate wascentrifuged at 3 500 r/min for 10 min and the protein content was determined. NOS achvity in the spinal dorsal hornwas measured using ultraviolet spectrophotometer. Results In group Ⅱ and Ⅲ pain threshold was significantlylowered and NOS activity significantly increased compared with those in group Ⅰ(sham operation) (P0 .05),but therewas signilicant difference in NOS activity between group Ⅱ and group Ⅳ, Ⅴ, Ⅵ (P

Objective To investigate the effects of rosiglitazone on the endothelial regeneration and neointimal formation after balloon injury in rat aortic.Methods Endothelial denudation of aorta in SD rats were performed with 2 F Fogarty balloon catheter.Male Rats were randomly divided into the sham-operated group,the control group,and the RSG group.Aortic tissues were harvested 7 days and 14 days after the injury.The endothelial regeneration rate,serum NO level,IA/MA ratio and PCNA expression index were detected.Results RSG enhanced the reendothelialization of the injured aorta determined by Evans blue staining.The RA/TA ratio on the 7~(th) day and the 14~(th) day were 38.20% and 75.20%(P

Objective To investigate the effect of intrathecal ketamine on the intracellular calcium ion concentration [Ca2+ ]1 in the spinal dorsal root ganglion (DRG) neurons in a rat model of chronic neuropathic pain produced by chronic constrictive injury (CCI) .Methods Thirty-six male SD rats weighing 160-180 g were randomly divided into 3 groups ( n = 12 each) : Ⅰ sham-operated group; Ⅱ CCI group and Ⅲ ketamine + CCI group. The animals were anesthetized with intraperitoneal pentobarbital 40 mg?kg-1 . The right sciatic nerve was exposed and 4 loose ligatures were placed on the trunk of the nerve at 1-2 mm interval. In sham-operated group (Ⅰ) the sciatic nerve was exposed but not ligated. Intrathecal catheter was implanted at L4,5 and correct placement was confirmed by aspiration of cerebro-spinal fluid. In group Ⅲ ketamine 1 mg ? kg-1 was administered intrathecally. 30 min before and on the 1st, 2nd, 3rd, 5th, 7th, 9th and 11th day after operation. In group Ⅰ and Ⅱ normal saline (NS) was given intrathecally instead of ketamine. Thermal and mechanical hyperalgesia were measured with ice-cold water and von-Frey filaments on the 7th and 14th day after operation. The animals were killed by cervical dislocation on the 7th (n = 6) and 14th ( n = 6) day. Bilateral DRG of L4-6 spinal nerve were removed and homogenized and centrifuged at 5 000 r/min. DRG neurons were isolated and [ Ca2+ ] i was measured by flow cytometry.Results In group Ⅱ (CCI) pain threshold to von-Frey hair stimulation decreased by 80.3% (on the 7th day) and 84.8% (14th day) while pain threshold to noxious thermal stimulation increased by 309.4% (the 7th day) and 336.2% (14th day) (P

Protein ubiquitination is one of the most important and widely exist protein post-translational modifications in eukaryotic cells, which takes the ubiquitin and ubiquitin chains as signal molecules to covalently modify other protein substrates. It plays an important roles in the control of almost all of the life processes, including gene transcription and translation, signal transduction and cell-cycle progression, besides classical 26S protesome degradation pathway. Varied modification sites in the same substrates as well as different types of ubiquitin linkages in the same modification sites contain different structural information, which conduct different signal or even determine the fate of the protein substrates in the cell. Any abnormalities in ubiquitin chain formation or its modification process may cause severe problem in maintaining the balance of intracellular environment and finally result in serious health problem of human being. In this review, we discussed the discovery, genetic characteristics and the crystal structure of the ubiquitin. We also emphasized the recent progresses of the assembly processes, structure and their biological function of ubiquitin chains. The relationship between the disregulation and related human diseases has also been discussed. These progress will shed light on the complexity of proteome, which may also provide tools in the new drug research and development processes.

OBJECTIVETo observe the effect of electroacupuncture (EA) combined with ultraviolet therapy on herpes zoster at the acute stage and the impacts on serum interleukin 2 (IL-2), interleukin 6 (IL-6) and interleukin 10 (IL-10) in the patients.

METHODSThirty-four patients of herpes zoster were randomized into a medicine group and a combined therapy group, 17 cases in each one. In the medicine group, the intravenous drops with acyclovir injection, muscular injection with cobamamide and the topical with acyclovir ointment were applied. Additionally, TDP was radiated locally. In the combined therapy group, on the basis of the treatment as the medicine group, EA and ultraviolet therapy were supplemented. The duration of treatment was 10 days in the two groups. Before and after treatment, blister relief, incrustation time and the visible analogue scale (VAS) were recorded in the two groups. The clinical efficacy was assessed in the two groups and the levels of serum IL-2, IL-6 and IL-10 were determined in the two groups.

RESULTSIn the combined therapy group, the time of blister relief and incrustation was earlier apparently than that in the medicine group (both P<0.05). VAS score after treatment were reduced as compared with that before treatment in the two groups (both P<0.01), and the reducing amplitude in the combined therapy group was larger than that in the medicine group (P<0.01). The total effective rate was 94. 1% (16/17) in the combined therapy group, higher than 76.4% (13/17) in the medicine group (P<0.05). After treatment, IL-2 levels were increased as compared with those before treatment in the two groups (both P<0.05), the levels of IL-6 and IL-10 were reduced obviously as compared with those before treatment in the two groups (all P<0.01). After treatment, the levels of IL-6, IL-10 were reduced much more apparently in the combined therapy group as compared with those in the medicine group (both P<0.05).

CONCLUSIONEA combined with ultraviolet irradiation more rapidly and effectively relief the symptoms of herpes zoster, significantly relief pain, shorten the duration of sickness, improve the body immunity and reduce nerve injury.
