As the actual clinical reflecting of transform Chinese medicine special curative effect, Chinese medicine preparation not only satisfies the need of hospital clinic, scientific research and teaching, but also plays an important role in deepening medical and health system reform, improving people's health level and contributing to the economic growth. However, some problems about administration and approval (tending to western medicine), contraction of the scale, lack of synchronization for clinic and scientific research, and the imbalance of regional development make Chinese medicine preparation move forwards slowly in contradiction. It has not only reduced the effectiveness of the Chinese medicine preparation in hospital clinic, but also brought bad effect on modernized development of Chinese medicine preparation. Research shows that main influencing factors of status quo of Chinese medicine preparation in medical institution include imperfect laws and regulations, high cost than income, and shortage of talents in preparation research. The analysis indicated that the necessary measures to break the contradiction, improve clinical effect of Chinese medicine, and promote the modernization development of Chinese drugs preparation were as follows: government and related departments should strengthen the supporting force in policy by adjusting the examination and approval policy, speeding up dispensing use, reforming pricing system, including into medicare reimbursement, integrating advantage resources and so on; medical institution should actively carry out research and development of traditional Chinese Medicine through drawing the traditional and modern essence, reserving professional talents, and developing characteristic preparation; companies cooperate with hospitals for complementary advantages, which can rapidly transform Chinese medicine preparation into clinical practice.

Qi in TCM is the most essential substance that makes up the body and maintains life activities. All vital substances in the body are transformed by constant motion and changes of qi. Qi in TCM mainly means full of functions. What is the basic material attribute of qi? We don't have a systematic study on it. Therefore, we combined the achievement of modern medicine, and explored further from the origin, functions, pathogeneses, and therapies of mitochondria and qi. Surprisingly, we found out that the origin of mitochondria was similar to that of qi. They are tiny substance constituting the human body. Secondly, the function of mitochondria is similar to that of qi. When the disorder of qi and mitochondria occurs, similar vital signs occur or the same reactions occur. These results suggested that the basic material attribute of qi might be mitochondria.

Objective To investigate the effect of 1, 25-dihydroxy-vitamin D3 (1, 25 (OH)2D3) on adipocyte differen-tiation and the underlying mechanism. Methods The mesenchymal stem cell line C3H10T1/2 was randomly divided into 6 groups including control group, differentiation group and 4 different doses of 1, 25(OH)2D3 groups. The control group was treated with vehicle. The differentiation group was supplemented with adipocyte differentiation reagent. And the 1,25(OH)2D3 groups were treated with adipocyte differentiation reagents and 10-9, 10-8, 10-7 and 10-6 mol/L of 25(OH)2D3. After culturing for 5 days, the cells were stained with oil red O, and the expression levels of adipocyte-specific transcription factors and Wnt/β-catenin signaling pathway related genes were examined by RT-PCR or Western blot methods. Results 1,25(OH)2D3 sig-nificantly reduced the number of differentiated adipocytes and blocked the mRNA levels of adipocyte specific transcription factor PPARγ(peroxisome proliferator-activated receptor gamma), C/EBPα(CCAAT enhancer binding proteinα) and adipo-cyte characterization factor aP2 (fatty acid binding protein 4). These were paralleled by the decreased mRNA expression of Wnt/β-catenin signaling pathway inhibitor sFRP1 (Secreted frizzled-related protein 1) and the increased level ofβ-catenin protein. Conclusion 1, 25(OH)2D3 inhibits adipocyte differentiation, which may be related to the activation of Wnt/β-catenin signaling.

Objective:To prepare and purify siRNA targeting a proliferation-inducing ligand targeted(APRIL-siRNA),so as to provxde a basis for studying the role of APRIL in human pancreatic cancer.Methods:pET-22b-APRIL was constructed to express APRIL dsRNA of human pancreatic cancer cell line CFPAC-1 in E.coli and the product was purified by chromatography using CF-11 column.APRIL dsRNA was digested by RNaseⅢto prepare APRIL siRNA,then the reaction mixture was loaded onto a DEAE ion exchange chromatography to remove RNaseⅢfrom oligonucleotides,and size exclusion chromatography was used to purify 21 bp siRNA.The purified APRIL siRNA was used to transfect Chinese hamster ovary(CHO)cells and the expression of APRIL in CHO cells was observed under fluorescence microscope Results:APRIL dsRNA was successfully expressed in E.coli after IPTG induction and was purified by CF-11 column.dsRNA was hydrolyzed with RNaseⅢand was purified by DEAE ion exchange chromatography and size exclusion chromatography.15% nondenaturing PAGE and 12% SDS- PAGE confirmed that RNaseⅢwas removed from oligonucleotides and 21 bp siRNA was purified with size exclusion chromatography.It was also found that APRIL siRNA obviously depressed APRIL expression in CHO cells.Conclusion:We have successfully constructed APRIL siRNA targeting APRIL gene of CFPAC-1 cells with in vitro transcription,which provides a basis for knock-down of APRIL gene in CFPAC-1 cells.

Objective To evaluate the effect of mild hypothermia on the activity of hippocampal pro tein kinase R-like endoplasmic reticulum kinase (PERK) in a mouse model of cerebral ischemia-reperfusion (I/R).Methods One hundred and twenty male C56BL6 mice,weighing 20-30 g,aged 7 weeks,were randomly divided into 3 groups (n=40 each) using a random number table:sham operation group (group S),I/R group,and mild hypothermia group (group H).Cerebral I/R was induced by occlusion of bilateral common carotid arteries for 15 min followed by reperfusion in anesthetized mice.In group H,surface cooling was performed immediately after reperfusion,and the rectal temperature was maintained at 32-34 ℃ for 3 h.In I/R and S groups,the rectal temperature was maintained at 36.8-37.2 ℃.At 6,12,24 and 72 h of reperfusion,10 mice were sacrificed in each group,and the hippocampi were removed for determination of the number of apoptotic neurons in hippocampal CA1 region (by TUNEL),and phosphorylated PERK (p-PERK) expression (by Western blot).Results Compared with group S,the number of apoptotic neurons was significantly increased,and the expression of p-PERK was up-regulated at each time point in I/R and H groups (P＜0.05).Compared with group I/R,the number of apoptotic neurons was significantly decreased,and the expression of p-PERK was downregulated at each time point in group H (P＜0.05).Conclusion Mild hypothermia can reduce endoplasmic reticulum stress through inhibiting hippocampal PERK activity,thus attenuating cerebral injury in a mouse model of cerebral I/R.

Objective Investigate the effect of insomnia on cardiovascular disease factors and offer the experimental evidence for treating cardiovascular disease with traditional Chinese medicine tranquillization methods. Methods Sixteen Wistar rats were randomly divided into two groups named sleep deprivation ( SD ) group and normal control check( CC) group.Body weight and electrocardiogram were recorded and serum concentrations of melatonin ( MT) , endothelin-1 (ET-1), IL-6 and TNF-αwere tested before SD and 2 days, 5 days, 7 days after SD.Results Body weight decreased in SD group while increased in CC group.Compared with CC group, body weight of SD rats decreased significantly in 5 days and 7 days after SD( P <0.05) .Compared with CC group, TNF-αincreased significantly in 5 days (P <0.05).With the time, heart rate accelerate and QTc were prolonged, MT decreased while ET-1, IL6, TNF-αincreased significantly in 7 days after SD (P <0.05).Conclusion Long term insomnia would decrease body weight and MT, while increase heart rate, QTc, ET-1 and inflammatory factors, which increase cardiovascular disease factors.It provided the experimental evidence for the study on traditional Chinese medicine tranquillization methods in the treatment of cardiovascular disease.

Objective To investigate the value of bone morphogenetic protein-7 (BMP-7) and the kidney shear wave velocity (SWV) in the diagnosis and treatment of diabetic nephropathy.Methods 150 cases of patients with diabetic mellitus were divided into three groups according to 24h urinary albumin excretion (Ualb):normalbuminuria (NA) group,microalbuminuria (MA) group and clinical proteinuria (CA) group;50 healthy subjects were selected as the control group (NC).The levels of blood BMP-7 were detected and the virtual touch tissue quantification (VTQ) was used to detect renal SWV in four groups.Both the BMP-7 level and the renal parenchyma SWV were compared among four groups.Then correlation analysis was made between blood of BMP-7 level and renal SWV in diabetic nephropathy groups.Results Blood BMP-7 level:the lowest was CA group,the middle one was MA group,and the highest was NA group (P ＜0.05),the NC group and the NA group had no significant difference (P ＞0.05); SWV measured values:CA group was the highest,MA group was middle one and the NA group was the lowest (P ＜ 0.05),the difference between NC group and the NA group was not significant statistically (P ＞0.05).The blood levels of BMP-7 and renal SWV had a significant negative correlation (r =-0.612,P ＜0.05).Conclusions The blood BMP-7 levels downregulate with the progressing of diabetic nephropathy,but the renal SWV increases with the diabetic nephropathy deterioration,and may indirectly reflects blood BMP-7 levels.Both of them have important application values in the diagnosis or treatment of diabetic nephropathy.
