Nowadays more and more attention has been paid to the problems about housing and health in China. Some investigations showed that people spent almost fourteen hours in their homes every day so the houses become the major places of daily activities. It is very important to solve the problems of what is the relation between the housing and health and how the housing influences the health of the people living in it. In the present paper the author summarized the overseas and domestic researches on the housing and health and pointed out that the research on housing and health in China is just in the preliminary phase.

Purpose: To evaluate the efficacy and adverse effects of letrozole for postmenopausal breast cancer patients with bone raetastases. Methods: Thity-six breast cancer patients with bone metstases received 2. 5 mg tablet letrozole every day. for at least two months. Results: In the 36 patients who were evaluable for efficacy and toxicity, the complete response rate (CR) , partial response rate ( PR) , disease stabilization rate ( SD) and progressive disease rate ( PD) were respectively 5.5% , 22. 2% , 55. 5% and 16. 6% . The clinical benefit rate ( CR + PR + SD ≥ 6 months ) was 58. 3% (21/36) with 11 patients (30. 5%) having SD for at least 6 months . Conclusions: Letrozole is a well tolerated agent with reasonable efficacy but low toxicity for postmenopausal breast cancer patients with bone metastases.

Objective:To assess the clinical efficacy of abdominal acupuncture for subhealth insomnia.Methods:Eighty-two cases of subhealth insomnia were randomly divided into an observation group (41 cases) and a control group (41 cases).The control group was treated with conventional acupuncture.The observation group was treated with Bo's abdominal acupuncture on the basis of conventional acupuncture.Six treatments constituted one treatment course.The measuring scale of traditional Chinese medicine syndrome for subhealth state (MSSSHS) and Pittsburgh sleep quality index (PSQI) scores were compared between the two groups after two courses,to estimate the efficacy of abdominal acupuncture for subhealth insomnia.Results:One case dropped out from the observation group,while 2 cases dropped out from the control group.The MSSSHS score and PSQI score both declined after the treatment in the two groups (all P＜0.05).The MSSSHS and PSQI scores in the observation group were significantly lower than those in the control group (both P＜0.05).Conclusion:The abdominal acupuncture is effective for subhealth insomnia,and it can enhance the effect of conventional acupuncture.

There are reports about the chemical compounds of Ciwujia herbs, but with no study report about the chemical material basis of Ciwujia injection (CWJI). In this study, LC-MS(n) and LC-Q-TOF-MS techniques were adopted for a qualitative analysis on phenylpropanoids in CWJI. The Ultmate XB-C18 column (4.6 mm x 250 mm, 5 microm) was adopted and eluted with the mobile phase of 0.5% formic acid-water and acetonitrile, with the flow rate at 0.8 mL x min(-1) and the column temperature at 20 degrees C. Based on the data of high-resolution and multi-stage MS, control products and literatures, altogether 54 phenylpropanoids were identified in Ciwujia Injection, including 34 phenylpropanoids, 16 ligans and 4 coumarins. Among them, 28 were reported for the first time in Ciwujia, and 14 compound structures were identified in comparison with the control products. The method established in this study could be used to simply and rapidly identify phenylpropanoids in CWJI. The findings provide scientific data for defining the chemical material basis of CWJI.

Objective To investigate the rehabilitation prognoses of children with traumatic brain injury (TBI).MethodsA retrospective analysis was made in 64 children who had been admitted for rehabilitation.Their clinical information,rehabilitation protocols,recovery of consciousness and ability in the activities of daily living (ADL) were analyzed. ResultsThe children's injuries were severe-42.19％ had consciousness disorders,but 80％ of them recovered consciousness after rehabilitation.Their limb motor dysfunction was dominated by hemiplegia (51.67％).For 65.63％ of the patients rehabilitation was initiated within one month after injury.The average length of stay in rehabilitation was 33.09 ± 25.96 days.Those with consciousness disorders stayed significantly longer than those without.The main treatments were hyperbaric oxygen therapy,exercise and neurotrophic drugs (the ratios were 95.31％,89.06％ and 82.81％ respectively).After the first course of inpatient rehabilitation,the conscious ness recovery rate was 81.48％ and ADL ability improved significantly.The total effectiveness rate was 90.63％.Univariate and multivariate analyses showed that the factors most strongly correlated with effective rehabilitation were age at injury and the rehabilitation intervention time.ConclusionThe results suggest that a general hospital should focus on early (acute and subacute phase) rehabilitation.So developing the rehabilitation network system is necessary and urgent.Rehabilitative therapy is very helpful in TBI cases.Being older at the time of injury and earlier rehabilitation intervention predict better short term outcomes.It is necessary to build and improve on a more standardized and systemic rehabilitation and assessment system for pediatric TBI.

Hirudin is one of the most potent anti-coagulant protein ever found, and its C-terminus is a key domain for inhibiting thrombin.In order to enhance its specificity,a novel anti-coagulant protein was constructed via fusing the C-terminus of hirudin to Annexin V, which was expected to sustain both anti coagulant activity and phorspholipid affinity. The structure of the designed protein was predicted with both molecular mechanics and dynamics. Molecular dynamics was adopted to simulate the docking interaction between the fusion protein and thrombin. The results showed the inhibitory activity of the fusion protein to thrombin.

The spores suspension of Streptomyces roseosporus D-38 irritated with 20mW He-Ne laser for 20 min were incubated on G1 medium plates containing 1. 9?g/mL of streptomycin. Ten percent of mutants increased the potency of daptomycin by streptomycin-resistance method, including the mutant LC-54, which could produce daptomycin 81. 2 mg/L, which was 39% higher than that of the beginning strain by flask fermentation.

Objective To investigate the effects of CD24 on CCl4-induced murine liver fibrosis and to analyze the possible molecular mechanism.Methods Wild type (WT) and CD24 knockout (CD24-/-) C57BL/6 mice were treated with CCl4 through intraperitoneal injection.Levels of ALT in serum samples were detected and liver tissues were stained with hematoxylin and eosin (HE) to assess liver tissue injury.Sirius Red staining was used to observe liver fibrosis.Real-time PCR was performed to detect the expression of α-SMA (α-smooth muscle actin), Col1a1 (Collagen, typeⅠ, alpha 1), TGF-β1 (transforming growth factor-β1) and CD24 at mRNA level in liver tissues.Western blot was performed to analyze the expression of α-SMA and Col1a1 at protein level.Flow cytometry analysis was used to detect the macrophages in liver tissues.ELISA was used to detect the expression of TGF-β1 in the culture supernatants of M1 and M2 macrophages.Results The expression of CD24 at both mRNA and protein levels were up-regulated in mice with CCl4-induced liver fibrosis.HE staining showed that liver inflammation in CD24-/-mice was more severe than that in WT mice after treated with CCl4.Sirius Red staining of paraffin-embadded liver sections revealed that compared with WT mice, CD24-/-mice presented with more severe liver fibrosis.Moreover, α-SMA and Col1a1, indicators of liver fibrosis, in CD24-/-mice were significantly higher than those in WT mice.Flow cytometry analysis showed that murine hepatic macrophages significantly increased in CD24-/-mice than in WT mice following CCl4 treatment.Real-time PCR analysis also confirmed that significantly enhanced expression of TGF-β1 at mRNA level in liver tissues was observed in CD24-/-mice than in WT mice.TGF-β1 secreted in the culture supernatant of M2 macrophages derived from CD24-/-mice group was more than that of the WT mice group.No significant difference in TGF-β1 secretion in culture supernatant of M1 macrophages was observed between the two groups.Conclusion Taken together, these data suggest that CD24 plays an important role in attenuating CCl4-induced chronic inflammation and hepatic fibrosis in mice.The mechanism of CD24 in alleviating liver fibrosis might be through regulating intrahepatic macrophages, inhibiting the secretion of TGF-β1 by M2 macrophages and suppressing the activation of hepatic stellate cells.
