Objective To analyze the bibliometry of the literature of acupoint thread-embedding in treating simple obesity, and to provide references for clinic.Method By both computer and manual retrieval, the relevant literatures over the past 30 years were collected from the Chinese Journal Full-text Database (CJFD), Vip database, WanFang database. By using the SPSS 17.0 software for statistical analysis, the distribution (province or city), publication year, and journal of the literatures, supporting fund, sample size, research method, material of the thread, use frequency of the involved acupoints, and the meridians of the selected acupoints were summarized.Result The included eligible 175 articles were distributed over many provinces and cities; the publication amount had been increasing year by year; there was a variety of thread materials; the literature with supporting funds only occupied a small percentage, while the research with a small sample size occupied a comparatively large percentage, and the randomized controlled trials (RCTs) also had a small percentage.Conclusion As a common Chinese external therapy in treating simple obesity, acupoint thread-embedding has been paid more and more attention for its practical value and bright future. However, the relevant governmental department hasn’t paid enough attention to this therapy, and the low clinical research quality also makes it difficult to scientifically evaluate its clinical efficacy and safety. Therefore, more attention is required, RCTs of multicenter and large sample size are expected, and clinical research quality also needs improvement, to provide references for clinic.

Objective To explore the effectiveness of the home-community-hospital network management (HCHNM) on the prevention and treatment of stroke.Methods From June to December 2011,HCHNM was implenented in Qingdao of Shandong Province to prevent and treat stroke patients.According to community residents healthcare records,A total of 80 stroke patients were randomly selected from Badahu and Fushanhou communities (study group) and another 80 patients from Zhongshan Road and Liaoning Road communities (control group).A household questionnaire survey was then conducted among these participants.Chi-square test and t test were used for data analysis.Results The overall effective rate of the study group was 86.25％ (69/80),which was significantly higher than that of the control group (67.5％) (x2=221.807,P＜0.05).The study group also showed largely improved quality of life (total score:t=4.593;physical fitness,family activities,movement,mood,self-care ability,social activities,upper limb function and work ability scores:t values were 7.775,2.244,5.329,3.832,5.463,2.979,5.924 and 3.555,respectively; all P＜0.05),although language,character,thinking and vision abilities had no statistically significant difference from the control group (t values were 0.561,1.466,0.831 and 1.000,respectively; all P＞0.05).The scores of daily activities and life satisfaction of the study group were higher than those of the control group,while per capita medical cost was much lower (t values were 12.998,20.760 and-29.777,respectively; all P＜0.05).Conclusions As an effective,safe and economy therapy model,HCHNM could improve rehabilitation,self-care ability,quality of life,and life satisfaction of community stroke patients.In addition,it greatly mitigates medical burden.

The relationship between acupuncture and stress is discussed from three aspects, including is it possible for acupuncture stimulation to be a stressor, whether acupuncture will start stress reaction, and whether acupuncture effects contain some stress factors. It is believed that correct acupuncture manipulation will not cause stress response, however, under some circumstances, such as inaccurate manipulation, improper treatment or patients who are very nervous but do not receive effective intervention, acupuncture is likely to cause stress response. Acupuncture-induced stress response is totally different from acupuncture anti-stress. The possible stress factors in acupuncture effect are explored, which can provide a new angle for the research on action mechanism of acupuncture. From the view of stress to review acupuncture treatment, there are three enlightenments: emphasizing on communication between doctors and patients, avoiding over-pursuit of deqi and focusing on analysis of the body constitution.

Objective To examine the expression of Toll-like receptor(TLR)4 protein and the transcription of TLR4 mRNA in the peripheral blood mononuclear cells(PBMC)from patients with hepatitis B virus(HBV)infection and explore the relationship between TLR4 and chronic HBV infec- tion.Methods The expression level and transcription level of TLR4 were determined by flow cytometre and reverse transcriptase polymerase chain reaction respectively in PBMC from 37 chronic hepatitis patients,28 liver cirrhosis patients,31 severe hepatitis patients and 27 healthy controls. Meanwhile,liver function,as well as blood routine test,prothrombin test activity(PTA)and HBV DNA was measured.Results The expression level and transcription level of TLR4 in patients were higher than those in healthy controls(P

Objective To investigate the MR imaging technique and features of acute radiation- induced hepatic injury with superparamagnetic iron oxide(SPIO)enhancement in a rabbit model.Methods On the 10th day after half-liver single 40 Gy X-ray irradiation,MR imaging before and after SPIO administration and pathologic study of 12 adult rabbits were performed.Results On the 10th post-irradiation day,TSE T_2 WI before SPIO enhancement,the irradiated liver of two rabbits showed relatively higher signal, and 1 showed slightly lower signal.With SPIO enhancement,the irradiated livers of 9 rabbits were found to be abnormal,manifesting as higher or slightly higher areas on multiple MR imaging sequences,especially the TFE T_1 WI sequence.Histological specimen with HE stain under light microscopy revealed occlusive injury of central veins(veno-occlusive disease,VOD)in each irradiated liver to some extent.Electron microscopy investigation of the irradiated liver disclosed intracellular edema,fibrin deposition,and widening of the Disse-space.Conclusion The early pathologic feature of the irradiated liver is occlusive injury of the central vein.MR imaging with SPIO enhancement is effective to valuate the early irradiation-induced liver injury.

Objective To identify human leucocyte antigen (HLA)-A* 0201-restricted hepatitis C virus (HCV)-cytotoxic T lymphocyte (CTL) epitopes. Methods Based on the prediction results of RANKpep and SYFPEITHI prediction programs, six candidate CTL epitopes were selected and synthesized. The affinity of candidate CTL epitopes to HLA-A* 0201 molecules of T2 cells was explored. Subsequently, enzyme-linked immunosorbent spot (ELISPOT) assay and intracellular cytokine staining (ICS) were utilized to determine whether candidate CTL epitopes could induce the recall positive response in peripheral blood mononuclear cells (PBMC) of HLA-A* 0201 positive HCV-1b-infected patients. Results Among six candidate CTL epitopes, peptides C_181(LLSCLTTPV) and NS2_172 (VLQAGLIRV) had high affinity to HLA-A* 0201 molecules. Moreover, the affinity was proportional to the concentration of peptide. Furthermore, among ten HLA-A* 0201 positive HCV-1b-infected patients, the frequencies of C_181 and NS2_172-specific interferon (IFN)-γ-producing cells were 0-19 spots forming cells (SFC)/1 × 105 PBMC and 0-20 SFC/1 × 105 PBMC, respectively.The percentages of C_ 181 and NS2_172-specific IFN-γ+ CD8+ T lymphocytes in total CD8+ T lymphocytes were 0.006%-0.065% and 0.005%-0.080%, respectively. Conclusion Peptides C_181 (LLSCLTTPV) and NS2_172 (VLQAGLIRV) are identified as novel HLA-A* 0201-restricted HCV-CTL epitopes.

Objective To explore the HLA-A2 restriction and immunogenicity of 5 previously identified HCV-speeific CTL epitopes. Methods Based on T2 cell, to explore the HLA-A2 restriction of previously identified HCV-specific CTL epitopes by MHC-peptide complex stabilization assay;To detect pep-tide-specific CTL in HLA-A2~+ PBMC stimulated by HLA-A2-restricted peptides by intracellular cytokine staining(ICS) and ELISPOT; To explore the cytotoxicity of peptide-specific CTL to same peptide-loaded T2 cells (target cells) by CTL cytotoxicity test. Results Among 5 previously identified CTL epitopes NS4b_78 (SMMAFSAAL) and NS5a_367 (TVSSALAEL) have high-affinity for HLA-A2 molecules(FI 1) ;ELISPOT results shown that NS4b_78(SMMAFSAAL) and NSSa_367(TVSSALAEL) induced high levels of IFN-γ-se-creting cells [(60±6) SFC/10~4 PBMC vs (4±1 ) SFC/10~4 PBMC, P < 0.01 ; (10 ± 3 ) SFC/10~4 PBMC vs (2±1 ) SFC/10~4 PBMC, P <0.01, respectively] ;ICS results indicated that there were high percentages of CD8~+ IFN-γ~+ T cells in total CD8~+T cells stimulated by these peptides [(2.33 ±0.22 ) % vs (0.05±0.01)%, P <0.001 ; (0.36±0.06)% vs (0.03±0.01)%, P <0.001, respectively]. Furthermore,peptide-specific CTL could effectively kill same peptide-loadcd T2 cells. Conclusion NS4b_78 (SMMAF-SAAL) and NSSa_367 (TVSSALAEL) were identified as HLA-A2-restricted CTL epitopes which could in-duce immune response in vitro.

Background Channelrhodopsin-2 (ChR2)is a cation channel isolated from the eyespot of Chlamydomonas algae and has been used to control neuron activity.The light stimulation is a more precise fashion whether space or time than that of electrical,magnetic and ultrasound stimulation. Objective This study was to construct a replication deficient recombinant adenovirus cxpression vector of ChR2 and to determine its function.Methods Human embryo kidney 293 (HEK293) cell line was cultured and passaged in DF12 medium containing 10％ fetal bovine serum(FBS).The ChR2 gene was cloned at the downstream of cytomegalovirus(CMV)promoter of the adenoviral shuttle plasmid pSB291 in sense direction,and the resultant recombinant plasmid pSB291-hChR2- GFP was transfected into HEK293 cell together with plasmid pBHG lox ( deltaE1,3 ) containing adenoviral genome,then small amounts replication deficient recombinant adenovirus expression vector of ChR2 (Ad-ChR2) was obtained.Through amplification gradient centrifugation and dialysis,pure Ad-ChR2 was obtained.Visual cortex cells derived from 4 1-day-old clean Long Evans rats were primary cultured with serum-free culture media and infected by AdChR2.When expressing green fluorescencc,those cells received the stimulated of blue light with 460 nm.Patch clamp technique was applied to record an action potential. Results After purification and concentration,the titer of AdhCHR2 reached 7.9×1010 PFU/ml.Twenty-four hours after transfect of Ad-ChR2,HEK293 cell membrane showed the green fluorescence for the recombinant plasmid with green fluorescence protein under the inversed fluorescence microscope.The HEK293 cells change their shape from flat to round 13 days after transfected.The primary cultured visual cortex cells exhibited the green fluorescence 3-5 days after infected by Ad-ChR2.The action potentials evoked by blue light stimulation were recorded with patch clamp on those cells expressing green fluorescence. Conclusions Ad-ChR2 expressing vector is constructed successfully in this study.It is verified that Ad-ChR2 expressing vector can infect visual cortex cells with visual function.This result is very important for visual plasticity study.
