OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

Alzheimer' s disease (AD) is the most common form of dementia in the elderly. AD is an invariably fatal neurodegenerative disorder with no effective treatment. Senescence-accelerated mouse prone 8 (SAMP8) is a model for studying age-related cognitive impairments and also is a good model to study brain aging and one of mouse model of AD. The technique of cDNA microarray can monitor the expression levels of thousands of genes simultaneously and can be used to study AD with the character of multi-mechanism, multi-targets and multi-pathway. In order to disclose the mechanism of AD and find the drug targets of AD, cDNA microarray containing 3136 cDNAs amplified from the suppression subtracted cDNA library of hippocampus of SAMP8 and SAMR1 was prepared with 16 blocks and 14 x 14 pins, the housekeeping gene beta-actin and G3PDH as inner conference. The background of this microarray was low and unanimous, and dots divided evenly. The conditions of hybridization and washing were optimized during the hybridization of probe and target molecule. After the data of hybridization analysis, the differential expressed cDNAs were sequenced and analyzed by the bioinformatics, and some of genes were quantified by the real time RT-PCR and the reliability of this cDNA microarray were validated. This cDNA microarray may be the good means to select the differential expressed genes and disclose the molecular mechanism of SAMP8's brain aging and AD.

Objective To explore the correlation between the two methods of pulmonary arterial thermodilution technique(ThDCO)and pulse indicator continuous cardiac output(PiCCO)in determining hemodynamic changes in patients undergoing orthotopic liver transplantation(OLT).Methods Eighteen patients with end-stage liver disease(ASAⅡ-IV)were performed OLT and monitored hemodynamic changes by PiCCO method and ThDCO method simultaneously.The hemodynamic parameters including mean arterial pressure(MAP),cardiac output(CO)and systemic vascular resistance(SVR)were measured at different time points before anesthesia induction,after tracheal intubation,after the beginning of operation,at anhepatic phase,at neohepatic phase,at the end of operation,and after operation.Results Good correlation was found between the two methods for the determination of CO and SVR(r=0.987,P0.05).Conclusion The hemodynamics change dramatically in patients undergoing OLT.There is good correlation between the two methods of PiCCO and ThDCO for perioperative hemodynamic monitoring in patients undergone OLT,and PiCCO detection can be used conveniently for real-time continuous monitoring.

Traditional Chinese medicine (TCM) is the scientific therapeutics derived from the traditional Chinese physician's considerable clinical practice during the long history, with the characteristic of significant clinical therapeutic effects. The therapeutic philosophy of TCM is integrative medicine and pattern differentiation. The ideas of systems biology on the study of TCM were formed after the micro-and macro-outcome of systems biology being used into the practice of study on TCM. It is very important for the inheritance and development of TCM to disclose the basic mechanism of the clinical therapeutic effects of TCM and find new drugs, from the herbal preparation, pharmacology and pharmacokinetic to drug development using modern science technologies based on the theory of TCM.

OBJECTIVE To construct the neuroendocrine immunomodulation (NIM) sub-network regulated by Liuwei Dihuang decoction (LW) and analyze its characteristics. METHODS We took the GSE57273 in GEO database and screened the differentially expressed genes (DEGs)(P<0.01) by the GEO2R tool as gene expression signature of LW. The global PPI network was constructed in the context of whole PPI network through direct interaction algorithm and forest algorithm respectively.Then the enrichment and the topological characteristics of NIM signaling molecules were evaluated by permutation test. Finally, we abstracted the NIM sub-network by NIMNT, which combined the NIM molecular network and forest algorithm, and analyzed the topological characteristics of it by the Network Analyzer(release 2.7)plugin in Cytoscape v3.5.1.RESULTS We got 2468 DEGs in the gene expression signature of LW.After analyzing the global PPI network of LW got by two kinds of algorithms,we found that the NIM signaling molecules significantly enriched and located in important positions in the global PPI network. The NIM sub-network regulated by LW contained 1099 nodes and 1056 edges. We screened out 22 hub nodes (Degree>10). Among them, there were 19 NIM signaling molecules in which only ESR1 changed significantly and 3 non-DEGs(NFATC2,RARA,TP53).However,the down-stream of the hub nodes were significantly changes. CONCLUSION The results suggested that LW might mainly regulate the non-hub nodes to recovery of the network imbalance of the body in the state of disease.

Firstly discovered in 1980s,human immunodeficiency virus (HIV) continues to affect more and more people.However,there is no effective drug available for the therapy of HIV infection.Betulinic acid existing in various medicinal herbs and fruits exhibits multiple biological effects,especially its outstanding anti-HIV activity,which has drawn the attentions of many pharmacists.Among the derivatives of betulinic acid,some compounds exhibited inhibitory activities at the nanomolar concentration,and have entered phase Ⅱ clinical trials.This paper summarizes the current investigations on the anti-HIV activity of betulinic acid analogues,and provides valuable data for subsequent researches.

OBJECTIVE To investigate the effect and mechanisms of Liuwei Dihuang Decoction (LW)on cognition in PrP-hAβPPswe/PS1ΔE9(APP/PS1)transgenic mice.METHODS LW was adminis-trated with oral for 3 months.The locomotor activity test was performed to investigate the spontaneous motor activity of mice. The Morris water maze test and shuttle box test were performed to investigate the spatial learning and memory and active avoidance response respectively.The Αβ deposits and neuron loss in the hippocampus was detected by immunofluorescence staining and nissl staining respectively. The flow cytometry was employed to investigate the lymphocyte subsets of the mice.The 3H-thymidine incorporation was performed to investigate the splenocytes proliferation. RESULTS The treatment of LW ameliorated the impairments of spatial learning and memory and active and passive avoidance in APP/PS1 mice. The administration of LW alleviated neuron loss in the brain, suppressed amyloid-β (Αβ) deposits in the hippocampus of APP/PS1 mice. The treatment of LW significantly increased ConA-and LPS-induced proliferation of splenocytes,increased CD3+T cells and CD19+B cells in the spleen lymphocytes and reduced Gr1+cells in APP/PS1 mice.CONCLUSION This data indicated the adminis-tration of LW ameliorated behavioral and pathological deterioration via regulating immune function.

This study was aimed to investigate the apoptosis induced by bortezomib combined with As(2)O(3) in APL cell line NB4 and its mechanism. The apoptotic cells were detected by flow cytometry with Annexin V/propidium iodide double staining; the morphology of apoptotic cells was observed by Hoechst staining, Western blot was used to measure activation of caspase-3 and -9 as well as expression of NOXA; the siRNA technique was used to specifically silence NOXA gene; the lipofectamine 2000 was used to transfect pEGFP-Noxa plasmid and pEGFP vacant vector. The results showed that the bortezomib combined with As(2)O(3) could induce significant apoptosis of NB4 cells and activation of caspase 3 and caspase 9, but As(2)O(3) (0.5 µmol/L) alone could not cause marked activation of caspase cascade and apoptosis of NB4 cells. The expression level of NOXA in NB4 cells induced by bortezomib combined with As(2)O(3) was up-regulated; the activation level of caspase-3 and apoptotic rate of NB4 cells treated by bortezomib combined with As(2)O(3) decreased after specifically silencing the NOXA gene. The high expression of NOXA induced by transfection of plasmid could enhance the caspase 3 activity induced by As(2)O(3) alone. It is concluded that bortezomib can enhance sensitivity of NB4 cells to apoptosis induced by As(2)O(3) which may be related with up-regulation of proapoptotic protein NOXA.
