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.

The Ebola virus belongs to the Filovirus family, which causes Ebola hemorrhagic fever (mortality, 25%-90%). An outbreak of infection by the Ebola virus is sweeping across West Africa, leading to high mortality and worldwide panic. The Ebola virus has caused a serious threat to public health, so intensive scientific studies have been carried out. Several vaccines (e.g., rVSV-ZEBOV, ChAd3-ZEBOV) have been put into clinical trials and antiviral drugs (e.g., TKM-Ebola, ZMAPP) have been administered in the emergency setting to patients infected by the Ebola virus. Here, recent advances in vaccines and drugs against the Ebola virus are reviewed.

Objective: To observe the clinical efficacy of combined tuina manipulations with Qi Zheng Qing Peng paste for herniation of the lumbar intervertebral disc. Method: All 568 cases were randomly allocated into an observation group (189 cases), control Ⅰ group (187 cases) and control Ⅱ group (192 cases). Combined tuina with Qi Zheng Qing Peng paste, combined tuina with diclofenac diethylamine emulsions and tuina alone were adopted in the above three groups respectively. The efficacies in the three groups were compared after 4 weeks of treatment. Results: The total effective rates in the observation group, control Ⅰ group and control Ⅱ group were 89.9%, 86.6% and 84.9% respectively, showing a significant difference (P ＜0.05) . Conclusion: Combined tuina manipulations with Qi Zheng Qing Peng paste works well for herniation of the lumbar intervertebral disc.

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 proper proportion of effective fractions in Shengmaisan(saponins of Radix ginseng,saponins of Radix ophiopogonis,Lignans of Fructus schisandrae)in different anoxia models.Methods Acute cerebral hypoxia was induced by sodium nitrite and decapitation in mice,and the orthogonal design was used in these two models to find the proper proportion of three effective fractions.The gasping time of the mice,which were decapitated was observed to compare the anti-anoxia effects of XZF with other clinical drugs,and cerebral ischemic reperfusion injury model of mice was also used to study the effect of XZF on related biochemical index.Results XZF(the proportion of saponins of Radix ginseng,saponins of Radix ophiopogonis,Lignans of Fructus schisandrae as 7 ∶ 2 ∶ 6)significantly prolonged the gasping time,and decreased brain nitrogen monoxidum(NO)content after reperfusion of the mice at dosages of 50 mg/kg and 150mg/kg.Meanwhile,XZF also reduced malondialdehyde(MDA)content and increased superoxide dismutase(SOD)activity at the higher dosage.Conclusion XZF obtained by experimental screening exerts a significant protective effect on cerebral ischemia injury in mice,which provide some pharmacological evidence for further development of new modern Chinese drug composed with effective fractions for cerebral vascular diseases.

Objective: To investigate the compliance of smoking cessation and the effect of smoking status on long-term clinical prognosis in male patients with acute coronary syndrome (ACS) after drug-eluting stent (DES) therapy. Methods: A total of 656 ACS patients after DES therapy were studied, according to the post-operative smoking status, the patients were divided into 3 groups: Non-smoking group,n=226, Quit smoking group,n=283 and Persistent smoking group, n=147. The patients were followed-up for the average of 27 months, the major adverse cardio-/cerebral-vascular events (MACCE) were recorded in detail, and the effect of smoking status for MACCE occurrence were evaluated by multivariable Cox regression analysis. Results: The pre-operative smoking rate was 65.5% (430/656) of patients and post-operative smoking rate was 22.4% (147/656). Compared with Non-smoking group and Quit smoking group, the patients in Persistent smoking group had the younger age (P<0.001), more patients with abnormal blood lipids (P=0.005) and having lower level of education (P<0.001). The all cause death rates in Non-smoking group, Quit smoking group and Persistent smoking group were at 1.8%, 1.1% and 6.1% respectively,P=0.004; the MACCE occurrence rates were at 7.1%, 5.3% and 15.0% respectively,P=0.002. Multivariable Cox regression analysis showed that post-operative smoking was the independent risk factor for MACCE occurrence, HR =1.404, 95% CI (1.206-1.793),P=0.008. Conclusion: Smoking is the independent risk factor for MACCE occurrence in male ACS patients after DES therapy.

OBJECTIVETo explore the action mechanism of electroacupuncture (EA) at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) on insomnia.

METHODSThirty SD rats were randomly divided into a blank group, a model group and an EA group, 10 cases in each group. The insomnia model was made by immobilization method in the model group and EA group. After model establishment, rats in the blank group and model group were treated with fixation and no treatment was given. Rats in the EA group were treated with EA at "Shenmen" (HT 7) and "San-yinjiao" (SP 6) for 15 min, once a day for 4 days. After treatment, the level of daytime and nighttime activity, open-arm entry percentage and open-arm time percentage of elevated plus-maze test were measured; the content of noradrenaline (NE), dopamine (DA) and epinephrine (EPI) in plasma and NE, DA in thalamus and brainstem were detected by using euzymelinked immunosorbent assay method.

RESULTSCompared with the blank group, the daytime activity was increased and nighttime activity was reduced in the model group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both reduced in the model group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were increased in the model group (all P<0. 05). Compared with the model group, the daytime activity was reduced and nighttime activity was increased in the EA group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both increased in the EA group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were reduced in the EA group (all P< 0. 05).

CONCLUSIONElectroacupuncture at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) can restrain the over-activity of the sympathetic-adrenal medullary system to treat the insomnia.

Objective To subclone express and identify the immune mapped protein 1 IMP1 which encodes a surface an?tigen of Toxoplasma gondii. Methods The cDNA of T. gondii RH strain was synthesized by reverse transcription PCR the IMP1 open reading frame ORF was amplified by PCR using the T. gondii RH strain cDNA as template the PCR products were identified by TA?cloning and sequencing then the IMP1 ORF was subcloned into the NdeⅠand Xho I sites of the vector pET28b and the positive recombinant pET28b?IMP1 was identified by double?digesting and sequencing. The protein of 6 × His tagged IMP1 was inducibly expressed in E. coli strain BL21 DE3 with isopropylβ?D?1?thiogalactopyranoside IPTG and the induction time concentration of IPTG and temperature gradients to optimize protein expression conditions were determined. After the cells carried IMP1 were induced by the optimized conditions and harvested the resulting bacteria were suspended in resuspension buffer and lysed by sonication and the supernatants were loaded onto the Ni2+Chelating Sepharose Fast Flow col?umn for affinity chromatography of the N?terminal 6 × His tagged IMP1 protein. Finally the fusion IMP1 proteins were identified by Western blotting. Results The ORF sequence of IMP1 was successfully subcloned from the cDNA of Toxoplasma Gondii RH strain and the amplified product was sequenced and identified based on which the IMP1 ORF gene was inserted into the prokaryotic expression vector pET28b and the recombinant pET28b?IMP1 was constructed successfully. The double?digesting and sequencing results indicated the validity of the recombinant vector. And the optimized conditions for the expression of IMP 1 was determined namely 0.3 mmol/L IPTG induction for 9 h at 20℃. Furthermore IMP1 protein was expressed solubly and che?lated on Ni2+sepharose beads with high affinity thus this protein could be purified efficiently by affinity chromatography. The pure fusion protein was confirmed with fine immunocompetence by SDS?PAGE and Western blotting. Conclusions IMP1 pro? tein can be high efficiently expressed by the E. coli prokaryotic expression systems the protein of IMP1 is soluble and has stable characters. The study may lay a useful foundation for the following works including in vivo expression of IMP1 crystal structure study of IMP1 and anti?toxoplasmosis subunit vaccine development.

Objective To investigate the curative effect of percutaneous transhepatic cholangial drainage(PTCD) on patients with non-anastomotic stricture after liver transplantation when treated with endoscopic retrograde cholangio-pancreatography(ERCP) unsuccessfully.Method The clinical data of 29 patients with non-anastomotic biliary stricture after liver transplantation were retrospectively analyzed,who failed to respond to ERCP and underwent PTCD from January 2005 to December 2007.Result All patients were performed PTCD successfully including cholangiography in 141 cases,drainage tube replacement in 115 cases,and balloon dilation of bile duct stricture in 39cases.The intubation time ranged from 2 months to 65 months.The mean levels (x ± SD) of alanine aminotransferase,aspartate aminotransferase and total bilirubin were 68.0 ± 29.1 U/L,52.6 ± 34.8 U/L,63.2 ± 33.3 μmol/L after treatment in comparison to 178.3 ± 63.3 U/L,144.0 ± 59.1 U/L,154.2 ± 92.0 μmol/L before treatment.Conclusion PTCD,which could improve the symptoms and prolong the survival time of both grafts and patients in spite of inconvenience of intubation,is suggested for patients with non-anastomotic biliary stricture if they are not suitable for liver retransplantation.

ObjectiveTo evaluate the feasibility and efficacy of ex-vivo liver resection combined liver autotransplantation for patients with massive primary liver cancer who underwent complex liver resection.Methods The clinical data of 4 patients suffering from massive primary liver cancer who were admitted to the Beijing Chaoyang Hospital from January 2008 to May 2010 were retrospectively analyzed.Regular liver resection could not be carried out because the first,second and third hepatic hilum of the 4 patients were invaded by the tumors,so ex-vivo liver resection combined liver autotransplantation were performed.ResultsThe operation was successfully carried out for the 4 patients.The operation time,the duration of anhepatic phase and the volume of operative blood loss were 690-840 minutes,250-300 minutes and 400-1400 ml,respectively.Portacaval bypass operation was not performed.After ex-vivo liver resection,the inferior vena eava or hepatic vein and portal vein of the 4patients were repaired,and the allogenous blood vessels were kept to extend the superior vena cava of the remnant liver so as to facilitate the anastomosis of blood vessels and reconstruction of the first hepatic hilum. After operation,the hepatic function of 1 patient was back to normal; 1 patient who stfffered from abdominal hemorrhage received reoperation for hemostasia; 1 patient was found with hepatic dysfunction; 1 patient died of hepatorenal dysfunction at postoperative day 5.Compensatory hypertrophy was observed in the 3 patients who survived at postoperative months 1-2.Of the 3 patients,2 were found with multiple pulmonary metastases at postoperative months 8 and 9,and they died at postoperative mouths 13 and 15.Until April 2012,1 patient survived for 37 months with no tumor recurrence or metastasis. ConclusionsEx-vivo liver resection combined liver autotransplantation provides the technical feasibility for performing complex liver resection for patients. The incomplete compensation of liver function and the short-term recurrence of tumors after operation are still the main issues which hinder the development of this technique.
