Chemical constituents of the essential oil in above-ground and root of Bupleurum malconense and root of B. chinense were investigated by GC-MS compiled with automated mass spectral deconvolution and identification system (AMDIS) and retention index. The results showd that the components of essential oil in B. malconense have some similarities with the one in B. chinense, and both of them have the higher content of caryophyllene oxide which is an active component of anti-inflammatory and analgesic. These results suggested that as a local substitute, B. malconense has a certain scientific basis of the treatment for cold fever.

Objective:To evaluate the effect of humanistic care for medical care integration on quality of life in elder patients with mild cognitive impairment. Method:Seventy patients with mild cognitive impairment in our hos-pital were randomly divided into experimental group ( n=35 ) and control group ( n=35 ) using random number ta-ble. The patients in the control group were given routine care, while those in the experimental group were given hu-manistic care for medical care integration and home visiting once a month besides routine care. All the patients were evaluated by the Montreal Cognitive Assessment Scale ( MoCA) , Activities of Daily Living ( ADL) , and the MOS Item Short from Health Survey ( SF-36 ) during hospitalization, three months and six months after hospital discharge. Result:Three and six months after hospital discharge, the scores of these three scales of all subjects in two groups were significantly higher than those during hospitalization ( P<0 . 05 ) . The scores of the subjects in the experimental group also significantly higher than those of the control group, and the differences were statistically significant (P<0. 05). Conclusion: For the elder patients with mild cognitive impairment, humanistic care for medical care integration can significantly improve the cognitive function, self -care ability and quality of life. Therefore, it is worthy using in clinical treatment.

OBJECTIVE: To analyze 113 patients with drug-induced liver disease(DILD) so as to clinically validate the international generally-accepted diagnostic criteria.METHODS: 113 DILD cases were reviewed and categorized according to international generally-accepted diagnostic criteria and then graded separately by Maria clinical scale and DDW-J scale to analyze the correlations.RESULTS: 113 out of 822 patients with liver diseases were DILD(13.7%),among whom 17 were of hepatocellular type(15.0%),92 cholestasis type(81.5%) and 4 mixed type(3.5%).Application of Maria clinical scale and DDW-J scale led to different number of DILD cases diagnosed.DILD were mostly induced by antihyperlipidemic drugs and immunosuppressants followed by anticoagulant drugs.CONCLUSION: DDW-J scale,which is more close to clinical diagnostic criteria,contributed to the standardization of the diagnostic criteria of DILD,yet it has its limitations as well.

Objective To generate a prokaryotic expression system of Salmonella paratyphi A nmpC gene that encoding an outer membrane protein(OMP),and to determine immunogenicity and immonuprotection of the recombinant expressed product rNmpC and carrying and expression frequencies of the nmpC genes in isolates of S.paratyphi A.Methods A nmpC gene clone was obtained from a clinical S.paratyphi A strain JH01 by PCR and T-A cloning method,and then a prokaryotic expression system of the gene clone was generated.SDS-PAGE and Bio-Rad Agarose Image Pattern Analysis System were applied to examine the expression and yield of rNmpC.Antigenicity and immunoreactivity of rNmpC were determined by immunodiffusion test,Western blot assay and micro-Widal's test.The carrying and expression rates of nmpC genes in 98 S.paratyphi A isolates were detected by PCR and ELISA.By a mouse infection model,the immunoprotective effect of rNmpC against the lethal challenge of S.paratyphi A was determined.Results All the cloned nmpC genes had 100% nucleotide and putative amino acid sequence identities compared to the reported sequencing data.The expression yield of rNmpC was approximately 30% of the total bacterial proteins.rNmpC could efficiently induce rabbits to produce specific antibody and present positive Western hybridization signals with S.paratyphi A antiserum.All the tested S.paratyphi A strains have nmpC gene as well as express NmpC protein,but no nmpC gene could be detectable in S.typhi,S paratyphi B and S paratyphi C.Immunization with 100 μg and 200 μg rNmpC contributed 41.7%(5/12) and 66.7%(8/12) immunoprotective rates in mice,respectively.The sera from rNmpC immunized mice and survival mice in the NmpC is an unique OMP antigen of S.paratyphi A with conserved sequence,extensive distribution and natural expression.This OMP can be used as one the candidate antigens for developing multiple-valence genetic engineering vaccine of S.paratyphi A based on its fine immunogenicity and certain immunoprotection.

Absrtact: Osteoarthritis (OA) is a most common form of degenerative joint disease, primarily characterized by the degradation of articular cartilage, subchondral sclerosis and inflammation of the synovial membrane. Mesenchymal stem cells (MSCs), a multipotent adult stem cell population, can be isolated from many connective tissue lineages, including those of the diarthrodial joint. Joint-resident MSCs or MSC-like progenitor cells contribute to the maintenance of healthy microenvironment or to the response to trauma. The onset of degenerative changes in the joint related to abnormal condition or depletion of these endogenous MSCs and native host hyaline cartilage cells, leading to limited self-repair potential of the joint and advance of the degradation. To date, no acknowledged medical treatment strategies, including non-operative and classical surgical techniques, are efficient in restoring normal anatomy and function of hyaline cartilage in OA. This highlights an urgent need for better celled-based therapeutic strategies that supplement these functional cells exogenously to recover the tissue homeostasis and repair in joint cavity via chondrogenic and anti- in fl ammatory functions. In this review we focus on the role of native MSCs in healthy or OA joint and recent progress in cell-based researches utilizing culture-expanded chondrocytes, pluripotent stem cells, or MSCs from different sources for treating OA.

Objective To observe the impacts of Kechuanning on expression of signal transducer and activator of transcription 6 (STAT 6) in CD4+, CD8+T lymphocytes of athma rats induced by virus, and analyze the mechanism of Kechuanning in treating asthma induced by RSV. Methods The PBMC was isolated from the peripheral blood, CD4+T, CD8+T lymphocyte was separated by immunomagnetic beads. The purity and activity of CD4+T and CD8+T lymphocytes were measured by using flow cytometry, trypan-blue dye exclusion test. The protein expression of STAT6 was detected by fluorescence-activated cell sorting. Results The descending progress of the trial were supported by the purity and activity of CD4+T, CD8+T lymphocyte. CD4+T lymphocyte in the asthma model group were increased (P<0.01), however the increase of CD8+T lymphocyte were not significant (P>0.05). The expression of the protein of STAT6 in the treated group with Kechuanning decoction were decreased than that in the model group (P<0.01). Compared with Dexamethasone and Salbutamol group, there were no significant differences (P>0.05). Conclusion Kechuanning decoction could decrease the protein of STAT6 in CD4+, CD8+T lymphocyte, thereby it could regulate the disorder of Th1/Th2, thus prevent and treat the asthmatic attack induced by virus.
