AIM: To observe the mRNA expressions of Insulin-induced gene 2(Insig-2) and Vitamin D receptor(VDR) in HepG2 cell line and investigate the possible mechanism of berberine on regulating blood lipid. METHODS: HepG2 cells were incubated with Bet at different concentrations(1,3,10,30,100 ?mol/L),and incubated with 3 ?mol/L berberine for various times(0,12,24,48,72 h).Total RNA was extracted and the mRNA expressions of Insig-2 and VDR from HepG2 cells treated by berberine were quantified by RT-PCR.(RESULTS): After exposure to gradient concentrations of berberine for 24 h,the mRNA expressions of Insig-2 and VDR in HepG2 cells increased obviously peaked at 3 ?mol/L concentration,then the up-regulating effect declined gradually.The relative coefficient between them was(0.753)(P

Chronic wound has very complicated pathogenesis and is difficult to treat;the situation has been improving owing to the progress in wound healing research and the clinical application of new techniques.This article focuses on the pathogenesis of chronic wound and introduces progress in various kinds of treatment,such as skin substitute,growth factors,negative pressure treatment,etc.

Objective:To investigate the mechanism of WWOX regulating immunosuppression in Lewis lung cancer cells.Methods:Transfected pCDNA4.0/myc-WWOX plasmid was transfected into Lewis lung cancer cells to detected the effect of cell supernatant on generation of lymphocytes by MTT method,and mRNA expression of immunosuppression factors by semi-quantitative RT-PCR.Function change of NK,CTL to kill tumor and lymphocte proliferation were analyzed by MTT and tumor volume.Results:The suppression of the supernatant to generation of lymphocytes was present compared with control group(P

Rheumatoid arthritis (RA) is an autoimmune disease, which is characterized by synovial inflammation. Hyperplasia sublining macrophages found in synovium is an early hallmark of RA and effective treatment results in their diminution. However, the origin of these sublining macrophages in synovium (including infiltrated macrophages and tissue-resident macrophages) are still unknown both in animal models of arthritis and RA patients, let alone the differences and feature of these macro?phages. In rheumatic synovium, macrophages are submitted to a large variety of micro-environmental signals which influence the phenotypic polarization and activation of macrophages. Understanding the mechanisms and functional consequences of the heterogeneous macrophages will contribute to confirm their potential role in synovial inflammation development. Furthermore, research on macrophage plasticity to soft-control their phenotypic polarization could lead to novel therapeutic approaches.

As a young discipline imported from the West,Chinese bioethics has made tremendous achievements in the last three decades.However,at the same time,there are also certain confusions about its ideaistic origins and academic development.Observing the trends in the growth of western bioethics and the changes in the contemporary real social life,we can see that it is the time to break the current bottleneck for the contemporary development of Chinese bioethics.Specifically,Chinese bioethics should shift its attention to the quality of life,and manifests its thought depth and academic value through reflecting the reality.Advancing with the times,the bioethics is bound to have a brighter future.

Objective To integrate nurses' humanistic quality into professional nursing training, in order to improve humanistic quality and nursing quality. Methods Nurses with working years within 6 years in our hospital were chosen from May, 2009 to May, 2010. And through non-professional reading, specified materials reading, multimedia lectures, particularly the refining and essence of reading reports, humanities knowledge and humanistic care consciousness was melted into personal morality, words, deeds and cultivation. Investigation about satisfaction degree was carried out among patients before and after the training. Results Satisfaction degree of patients increased after training, so did the satisfaction degree of nurses to reading reports. Conclusions To integrate nurses' humanistic quality into professional nursing training can improve humanistic quality of nurses and nursing quality. Nurses' professional image will be increasingly standard, overall quality and service quality can be improved, and thought of dedicated service for patients will be consolidated.

Objective:To develop HMGA1-silencing SMMC-7721 cell and investigate its impacts on apoptosis and cell cycle in tumor cells.Methods:Constructing HMGA1-silencing SMMC-7721 cell through G418 selection of RNAi plasmid transfected cells;surveying the apoptosis,prliferation and cell cycle of the tumor cells by FACS and MTT.Results:Stable HMGA1-silencing cells were obtained successfully.The apoptosis percentage in RNAi group(29.46?3.04%) was significantly higher than that in the negative control (1.96?0.76%) or control (2.04?0.70%)within each P

Objective To observe the effect of bone marrow mesenchymal stem cells (BMSCs) transplantation on the expression of growth associated protein-43 (GAP-43) in rats after spinal cord injury (SCI). Methods The SCI models were made by impacting at the level of T11 segment. After modeling, the rats were randomly and equally divided into control group (n=18) and observation group (n=18). 1 week after injury, DMEM/F12 medium 0.1 ml was injected into tail vein of rats in the control group, and an equal volume of BMSCs suspension was injected in the observation group. 1, 2, 4, 8 weeks after SCI, the hindlimb function was evaluated by the Basso-Beattie-Bresnahan (BBB) score. 2, 4, 8 weeks after SCI, the expression of GAP-43 mRNA was detected by RT-PCR, and the expression of GAP-43 was detect-ed by the immunohistochemistry. Results 2, 4, 8 weeks after SCI, compared with the control group, The BBB score increased, the expres-sion of GAP-43 mRNA and GAP-43 increased in the observation group (P<0.05). Conclusion BMSCs transplantation can improve the ex-pression of GAP-43 in gene and protein level, and then promote the repair of SCI.

Objective To compare the clinical efficacy of acupuncture and medicine for the treatment of chronic pharyngitis. Methods Sixty chronic pharyngitis patients were randomized into treatment group and control group, 30 cases in each group. The treatment group was treated with acupuncture mainly on acupoints of Zhaohai(KI6), Lieque(L7), Tiantu(CV22) , Lianquan(CV23), Tianrong(SI17) , Hegu(LI), Yuji (LU10) for nourishing yin to reduce fire and clearing throat. The supplementary acupoints were selected according to the symptoms and physical signs. Acupuncture was performed once a day and 6 times a week. The control group received western medical therapy including pharyngeal application with 1% iodine glycerin preparation and oral use of Cydiodine tablets, 3 times per day. Four weeks constituted one treatment course and the treatment for the two groups covered 2 courses. After treatment, the therapeutic effect was evaluated. The scores of the signs and s ymptoms as well as scores of chronic pharyngitis syndrome discomfort rating questionnaire(CPSDQ) evaluated by visual anal og scale(VAS) were observed. Results (1) The overall effective rate of the treatment group was 93.3%, higher than that of the control group(73.3%), and the inter-group difference was statistically significant (P<0.05). (2) After treatment, scores of the signs and symptoms and VAS for CPSDQ scores in the two groups were reduced as compared with those before treatment(all P<0.05 or P<0.01 ) .The improvement of the scores in the treatment group was superior to that in the control group(all P<0.05 or P<0.01).(3) During the treatment , needling-induced mild pain and bleeding occurred in the treatment group. No acupuncture syncope, stuck needles or allergic and toxic-side effect was shown in the two groups. Conclusion Acupuncture therapy can obviously relieve the symptoms, signs and discomfort in the patients with chronic pharyngitis, and the curative effect is superior to the drugs.
