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.

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.

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.

OBJECTIVETo explore the effect of Danlou Tablet (DT) on arrhythmia model rats induced by transient myocardial ischemia/reperfusion (I/R).

METHODSTotally 45 healthy Wistar rats were randomly divided into 3 groups, the sham-operation group, the model group, and the DT group, 15 in each group. Rats in the sham-operation group and the model group were administered with distilled water by gastrogavage at the daily dose of 0.1 mL/kg. Rats in the DT group was administered with 0.53 g/mL DT suspension by gastrogavage at the daily dose of 0.1 mL/kg. All medication was lasted for 10 successive days. The myocardial I/R experiment was performed at 1 h after the last gastrogavage. ECG was performed before ligation and at I/R. The jugular arterial blood pressure of all rats was measured during the whole course. ST segment changes were observed at each time point of I/R. The ventricular fibrillation, the premature ventricular, the number and the duration of ventricular tachycardia within 30 min reperfusion were also observed. Activities of Na(+)-K+ ATPase and Ca2+ ATPase in the myocardium homogenate were detected as well.

RESULTSThe jugular arterial blood pressure and the heart rate were slightly lower in the DT group than in the model group, but with no statistical difference (P > 0.05). Compared with the sham-operation group, the degree of ST segment was obviously elevated in the model group at 0, 5, and 7 min (P < 0.05). It was significantly lower in the DT group than in the model group (P < 0.01). ST seg ment was more elevated at 5 min than at 0 min in the model group, but the degree of ST segment elevation was still obviously lower in the DT group than in the model group (P < 0.05). There was no statistical difference in the degree of ST segment elevation at 7 min between the two groups (P > 0.05). At 0 min when the decrement of ST segment exceeded one half the ischemia, there was no statistical difference in the degree of myocardial ischemia between the model group and the DT group (P > 0.05). Compared with the model group, the incidence of fatal and nonfatal ventricular fibrillation, the frequency and duration of ventricular tachycardia and premature ventricular beats were obviously lessened, and activities of Na(+)-K+ ATPase and Ca(2+)-ATPase increased (all P < 0.05).

CONCLUSIONSDT could significantly protect arrhythmias induced by transient I/R. Its effect might be related to lowering the degree of myocardial ischemia, and increasing ion transport channel related enzyme activities.

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.
