To clarify the origin and development of the traditional Chinese medicine "Duhuo" and "Qianghuo" with medicinal literatures. Medical literatures of past dynasties were analysed and combined with the modern material. The "Duhuo" in Herbal writing Shen Nong Ben Cao Jing include traditional Chinese medicine "Duhuo" and "Qianghuo", "Qianghuo" was separated from "Duhuo" due to the distinguish of clinical application. The origin of "Qianghuo" is Notopterygium incisum and N. forbesii, However, The origin of "Duhuo" is very complex, Angelica pubescens f. biserrata as authentic "Duhuo" was used from Song Dynasty. "Qianghuo" was originated from "Duhuo".

Objective To evaluate the effect of hydrogen-rich saline on the expression of phosphor-p38 mitogen-activated protein kinase (p-p38MAPK) during cerebral ischemia-reperfusion (I/R) in rats.Methods Seventy-two adult male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 3 groups (n =20 each) using a random number table:sham operation group (group S),I/R group and hydrogen-rich saline group (group I/RH).Cerebral ischemia was induced in chloral hydrate-anesthetized rats by 2 h middle cerebral artery occlusion in I/R and I/RH groups.The artery was only exposed but not occluded in group S.At 3 days before operation and immediately after onset of reperfusion,hydrogen-rich saline (0.6 mmol/L) 10 ml/kg was intraperitoneally injected in group I/RH,while the equal volume of normal saline was given in S and I/R groups.Neurological deficits were blindly assessed and scored at the end of 24 h reperfusion.The animals were then sacrificed,and brains were removed for microscopic examination and for determination of the cerebral infarct size (by TTC),brain water content,cell apoptosis (by TUNEL),and expression of p38MAPk and phosphor-p38MAPK (p-p38MAPK) (by immunohistochemistry and Western blot).Apoptosis index was calculated.Results Compared with group S,neurological deficit score,apoptosis index,brain water content and cerebral infarct size were significantly increased,and the expression of p38MAPK and p-p38MAPK was up-regulated in I/R and I/RH groups.Compared with group I/R,neurological deficit score,apoptosis index,brain water content and cerebral infarct size were significantly decreased,and the expression of p38MAPK and p-p38MAPK was down-regulated in group I/RH.The pathological changes of cerebral tissues were significantly attenuated in group I/RH as compared with group I/R.Conclusion Hydrogen-rich saline can reduce cell apoptosis through inhibiting p-p38MAPK expression,thus attenuating cerebral I/R injury in rats.

To clarify the origin and application development of the traditional Chinese medicine " Zi-hua Qianhu" and " Qianhu", the medicinal literatures of past dynasties and modern researches were analysed. The plant Angelica decursivum was used as a substitute for traditional Chinese medicine "Angelica sinensis Radix" for a long historical period, it is used incorrectly for traditional Chinese medicine "Qianhu" due to origin research in modern times. The plant origin of "Qianhu" is Peucedanum praeruptorum. There are significant differences in clinical applications and chemical composition of the two drugs. The same efficacy description of "Zi-huaQianhu" and "Qianhu" could not stop "Zi-huaQianhu" used as "Qianhu" in practical application. Therefore, we need to further research for the plant A. decursivum, delimit its medicinal attribution.

Objective To evaluate the effect of hydrogen on the activation of caspase-3 in brain tissues during cerebral ischemia-reperfusion (I/R) in rats.Methods Thirty-six healthy adult male Sprague-Dawley rats,weighing 220-250 g,were divided into 3 groups (n=12 each) using a random number table:sham operation (group S),I/R group and hydrogen group (group H).Cerebral ischemia was induced by occlusion of the middle cerebral artery followed by reperfusion in I/R and H groups.In group H,hydrogen-rich saline 5 ml/kg (0.6 mmol/L) was injected intraperitoneally at 3 days before establishment of the model and immediately after the onset of reperfusion.At 24 h of reperfusion,the rats were sacrificed,and hippocampal tissues were obtained for determination of neuroapoptosis (by TUNEL),apoptotic neuron count and expression of activated caspase-3 (by Western blot).The brain tissues in the ischemic area were obtained and stained with haematoxylin and eosin for examination of the pathological changes.Results Compared with group S,the expression of activated caspase-3 was significantly up-regulated,and the apoptotic neuron count was increased in I/R and H groups (P<0.05).Compared with group I/R,the expression of activated caspase-3 was significantly down-regulated,the apoptotic neuron count was decreased (P<0.05),and the pathological changes of brain tissues were significantly reduced in group H.Conclusion The mechanism by which hydrogen inhibits neuroapoptosis during cerebral I/R is probably related to inhibited activation of caspase-3 in brain tissues of rats.

Objective To retrospectively investigate the incidence of accidental awareness during general anesthesia in selective operation and analyze the influence factors of accidental aware-ness.Methods Patients scheduled for elective surgery requiring general anesthesia with artificial air-way during April 2013-July 2015 were collected.The incidence was obtained from postoperative fol-low-ups.Perioperative data and anesthetic drugs were collected to analyze influence factors. Results A total of 141 294 patients were enrolled.Eighty patients (0.06%)were definitely identified as awareness.Multiple regression analysis showed that awareness during operation was associated with total intravenous anesthesia (OR=5.181,95% CI 3.032-8.853),using laryngeal mask airway (OR=2.478,95% CI 1.544-3.977)and ASA Ⅲ or Ⅳ (OR=9.202,95% CI 5.475-15.466).Pre-medication of midazolam (OR=0.125,95% CI 0.080-0.196)and combination of sevoflurane (OR=0.193,95% CI 0.113-0.330)had lower incidence of awareness during operation.Conclusion Total intravenous anesthesia,using laryngeal mask airway and ASA Ⅲ or Ⅳ are risk factors of accidental awareness during general anesthesia.Premedication of midazolam and combination of sevoflurane may prevent awareness during operation.

Objective:To investigate the influence of sCD80-Linker-sCD40L fusion protein on the unspecific anti- tumor immunity in vitro.Methods:Ovarian cancer SKOV3 cells were separately transfected with recombinant adenoviral vectors containing sCD80-Linker-sCD40L fusion gene,sCD80 gene,sCD40L gene or with control adenovirus.The expres- sion of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of SKOV3 cells was determined by ELISA.Dendritic cells(DCs)were cultured with peripheral blood mononuclear cells from a patient with ovarian carcinoma.DCs and autologous T cells were co-cuhured and were exposed to different supernatants for 48 h. The allostimulatory effects of DCs on T cells were determined by mixed lymphocyte reaction(MLR).The unspecific kill- ing activities of induced T cells against SKOV3/K562 cells were measured by LDH-releasing assay.Results:ELISA assay showed that levels of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of transfeced SKOV3 cells were 2.791 ng/ml,1.956 ng/ml and 1.407 ng/ml,respectively.The fusion protein-exposed DCs ([0.382?0.053]vs[0.167?0.028],P

Objective To compare the clinical effects on Gartland type Ⅲ fractures in children by open reduction and external fixation with two parallel Kirschner wires and closed reduction.Methods From February 2013 to October 2016,84 children with Gartland type Ⅲ supracondylar fracture of humerus were selected and randomly divided into a control group and an observation group,each with a total of 42 cases.The control group received closed reduction treatment,and the observation group received open and external fixation with two parallel Kirschner wires.The two groups were compared on intraoperative blood loss,incision length,operating time,decreased degrees of carrying angle,reduced flexion-extension at the fractured side and the rates for good and excellent clinical effects.Results The observation group behaved significantly better than the control group in intraoperative blood loss,incision length and operating time (P＜0.05).The rates for good and excellent effects was 90.47％ in the observation group and 73.81％ in the control group,and there was obvious difference between the values in the two groups (P＜0.05).The observation group had the decreased degree of carrying angle statistically lower than that in the control group (P＜0.05),while the reduced flexion-extension at the fractured side was not significantly different from that in the control group (P＞0.05).Conclusion Open reduction and external fixation with two parallel Kirschner wires and closed reduction both gain their advantages when used to treat Gartland type llⅢ fractures in children,the former has high clinical effect,significantly recovered elbow joint function and low incidence rate for cubitus varus,and the latter has slight invasion,small incision while relatively low clinical effect and high incidence rate for cubitus varus.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

OBJECTIVETo evaluate the academic level and the popularity of the Chinese Journal of Hepatology in China in 2005.

METHODSWe used bibliometrics to analyze statistically the original articles of the Chinese Journal of Hepatology cited by Chinese periodicals included in the Wanfang Data in 2005.
