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 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.

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

Bone xenograft bone for the treatment of bone defect is one of the current research focus, which has advantages of extensive sources, low cost, simple preparation method. While the process of single bone xenograft bone in repairing bone defect is very long, and the clinical outcome is not satisfactory. The main problems focus on formation of bone and vascularization. Reconstituted bone xenograft combined with cells and xenogenic bone material could promote vascularization and bone fusion in vivo, thus achieve a clinical effect of autogenous bone in repairing bone defect.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.

The present study is to establish Caco-2/HT29-MTX co-cultured cells and investigate the transport capability of PLGA nanoparticles with different surface chemical properties across Caco-2/HT29-MTX co-cultured cells. PLGA-NPs, mPEG-PLGA-NPs and chitosan coated PLGA-NPs were prepared by nanoprecipitation method using poly(lactic-co-glycolic acid) as carrier material with surface modified by methoxy poly(ethylene glycol) and chitosan. The particle size and zeta potential of nanoparticles were measured by dynamic light scattering. Coumarin 6 was used as a fluorescent marker in the transport of nanoparticles investigated by confocal laser scanning microscopy. The transport of furanodiene (FDE) loaded nanoparticles was quantitively determined by high performance liquid chromatography. Colchicine and nocodazole were used in the transport study to explore the involved endocytosis mechanisms of nanoparticles. Distribution of the tight junction proteins ZO-1 was also analyzed by immunofluorescence staining. The results showed that the nanoparticles dispersed uniformly. The zeta potential of PLGA-NPs was negative, the mPEG-PLGA-NPs was close to neutral and the CS-PLGA-NPs was positive. The entrapment efficiency of FDE in all nanoparticles was higher than 75%. The transport capability of mPEG-PLGA-NPs across Caco-2/HT29-MTX co-cultured cells was higher than that of PLGA-NPs and CS-PLGA-NPs. Colchicine and nocodazole could significantly decrease the transport amount of nanoparticles. mPEG-PLGA-NPs could obviously reduce the distribution of ZO-1 protein than PLGA-NPs and CS-PLGA-NPs. The transport mechanism of PLGA-NPs and mPEG-PLGA-NPs were indicated to be a combination of endocytosis and paracellular way, while CS-PLGA-NPs mainly relied on the endocytosis way. PEG coating could shield the surface charge and enhance the hydrophilicity of PLGA nanoparticles, which leads mPEG-PLGA-NPs to possess higher anti-adhesion activity. As a result, mPEG-PLGA-NPs could penetrate the mucus layer rapidly and transport across Caco-2/HT29-MTX co-cultured cells.
