This study was aimed to observe the clinical curative effect of Thesium Chinese tablets in the treatment of chronic bronchitis (syndrome of phlegm heat in the lung). A total of 100 cases of chronic bronchitis (syndrome of phlegm heat in the lung) were randomly divided into two groups. The control group was treated with anti-inflamma-tion, relieving cough and asthma, phlegm removing and oxygen inhalation, maintenance of water electrolyte balance and other symptomatic treatment. In the treatment group, on the basis of treatments in the control group, Thesium Chinese tablets were given at the dosage of 1.6 geach time, 3 times a day. Both groups were treated for 1 course of 10 days. The results showed that clinical symptoms and traditional Chinese medicine (TCM) syndromes of quantizing integral were improved after treatment in both groups. And the therapeutic effect of treatment group was significantly better than the control group (P< 0.01). Thesium Chinese tablets can effectively shorten the time of clinical symptom improvement time, obviously improve the level of Ig among elderly patients with acute exacerbation of chronic bron-chitis, and enhance the immune function. It was concluded that the Thesium Chinese tablets can effectively improve the quality of life among patients with chronic bronchitis (syndrome of phlegm heat in the lung).

The procedure with two aperture was chosen in 11 cases and the incision was extended in 2 cases out of them. The operation visual field was clear and common bile duct and hepatic artery and port vein could be differentiated. The incidenec of complications was 5.3%(5/95) and no severe complication occurred. Conclusions Preoperative B-type ultrasonogrophy is a simple and effective method for the choice of incision of minicholecystectomy in the term of individuation

Eucommiae Cortex is one of the most common and effective traditional Chinese medicine to treat osteoporosis, whose mechanism of action on BMSCs has gradually been confirmed. BMSCs are pluripotent precursor cells of the osteoblast and the osteoclast. In addition to a multi-directional differentiation potential, BMSCs are also characterized of immune suppressive regulating function. This article is a review about the research on differentiation of osteoblasts by BMSCs, which provides a new thinking for further research.

BACKGROUND:Specific mechanism of stem cel transplantation for treatment of myocardial infarction has been not very clear. OBJECTIVE:To investigate the effect of H2O2 METHODS: Twenty-four C57BL/6 mice, 9 weeks old, were randomized into myocardial infarction group, embryonic stem cels group, H-pretreated mouse embryonic stem cels in vitro for treatment of myocardial infarction. 2O2 pretreatment group, with eight mice in each group, which were respectively injected 150 μL PBS, 150 μL embryonic stem cels (1×106), and 150 μL H2O2-pretreated embryonic stem cels (1×106 RESULTS AND CONCLUSION:Compared with the myocardial infarction group, the left ventricular end-diastolic diameter and left ventricular end-systolic inner diameter were significantly decreased in the embryonic stem cels ) at 1 week after modeling. At 3 weeks after transplantation, left ventricular end-diastolic diameter, left ventricular end-systolic inner diameter and left ventricular ejection fraction of mice in each group were measured by ultrasound. Myocardial colagen content was detected by Sirius red staining and the average colagen volume fraction was calculated. group and H2O2 pretreatment group, while the left ventricular ejection fraction was significantly increased (P < 0.05). Heart weight/body weight, left ventricular weight/body weight, and average colagen volume fraction were significantly lower in the embryonic stem cels group and H2O2 pretreatment group than the myocardial infarction group (P < 0.05). Therefore,in vitro H2O2 pretreatment enhances reduce the post-myocardial infarction myocardial fibrosis and greatly improve heart function.
