Objective To screen key genes related to deep vein thrombosis (TDVT) after trauma using gene function assembly analysis. Methods Thirty Sprague Dawley rats were randomized into control, thrombosis and non-thrombosis groups. Traumatic limb DVT models were established in rats through quantitative beating on the bilateral posterior limbs. The Genechip Rat genome 430 2. 0 genechips were applied to detect changes in genes expressions on difference phases of DVT. On the basis of the differential gene expressions in the thrombosis and non-thrombosis groups, the gene function assembly analysis was conducted to define the most significant and concentrated gene functions leading to the biological characters of DVT.Results B factor (bf), complement 4 binding protein α (C4bpα), plasminogen activator inhibitor 1 (serpinel), urokinase-type plasminogen activator receptor (plaur) were screened to be the key genes related to DVT, because they were found to be involved in the functions like complement activation, development,growth, morphogenesis, primary metabolism, cell motility, protein metabolism, localization of cell, locomotion and localization. The abundance values of the genes expressed were 1.6, -0. 2, 2. 1, 5. 1 in the thrombosis group, and -0. 5, - 1.4, 2. 7, 3. 3 in the non-thrombosis group. Conclusion Bf, C4bpα,serpinel, plaur may be the key genes that play a role in the process of DVT.

Objective To observe the clinical efficacy and safety ofZhilou Lotion combined with modified Sihuang Ointment in treatment of anal cryptitis.MethodsOne hundred patients with anal cryptitis were randomly divided into observation group and control group, with 50 cases in each group. The control group was given propylene dispersible tablets oral and topicalHuazhi embolism. The observation group received steaming and hip bath with Zhilou Lotion combined with modifiedSihuang Ointment topical external application treatment, 7 days as a course of treatment and 2 courses successive. The TCM syndrome scores of two groups were compared before and after treatment to evaluate the clinical efficacy. The remission time of symptoms, hospitalization time, recurrence rate in 6 months and adverse reactions were observed.Results After treatment, the TCM syndrome scores of two groups were improved (P<0.01), and the scores in the observation group was lower than those in the control group (P<0.01).

Objective:To assess the preventive and therapeutic effects and primary mechanisms of Danshen injections in the treat-ment of hepatic encephalopathy ( HE) . Methods:The acute ammonia poisoning model induced by ammonium chloride was established in mice, and HE model with liver injury induced by carbon tetrachlorie and high blood ammonia induced by thioacetamide was made in rats. The time of death was detected in the first model, and the histamine levels in blood and brain, liver function and liver pathologi-cal histology changes were detected respectively in the other model. Results:In the acute ammonia poisoning experiment, the time of death in Danshen injections group was longer than that in the control group. Furthermore, Danshen injections could notably decrease the histamine levels in blood and brain, reduce the levels of ALT, AST, ALP and Tbil in serum and improve the function of liver to show the preventive and therapeutic effects on HE. Conclusion:Danshen injections exhibit promising preventive and therapeutic effects on HE, which may be related to decreasing histamine levels in blood and brain.

OBJECTIVE: To investigate the correlation between tongue body MRI measurements and the lingual region obstruction in patients with obstructive sleep apnea hypopnea syndrome (obstructive sleep apnea hypopnea syndrome, OSAHS), and the relationship of two diagnosis methods in positioning obstructive level, in order to improve the preoperative diagnostic accuracy of obstructive level in OSAHS patients . METHOD: Fifty-nine patients with OSAHS definited by the AG200 sleep apnea monitoring and obstruction plane positioning system was included. They all underwent tongue MRI scan, after three-dimensional reconstruction, the tongue body length to diameter, relative thickness, basal diameter, wide around central about wide diameter and tongue body volume were measured. The lower blocking (mainly composed of lingual region) constituent ratio P established by AG200 was correlated with tongue parameters measured by MRI. At the same time, To analysis of differences of P in patients with different degree of OSAHS. RESULT: Among these patients with OSAHS in different degree, the coefficient correlation between tongue parameters(tongue length, relative thickness, basal diameter, wide middle diameter, tongue body volume) and lower blocking constitute ratio P werer LP = 0.051,rHP = 0.069, r1 = 0.215, r2 = 0.147, rVP = 0.259, respectively. lower obstruction of form than the differences had statistical significance. The measured tongue parameters and value P(the lower blocking constituent ratio) were negatively correlated, which demonstrated that exclusing of the larynx and hypopharynx airway obstruction, the lower airway obstruction detected by AG200 was related with tongue parameters measured by MRI, and was strongestly related with the tongue body volume. CONCLUSION The volume of tongue and AG had correlation in judgement of lower blocking. In OSAHS patients the lower blocking constituent ratio varies between the defferent severity groups of the disease, the combina tion of the two method can be used to predict the obstructive plane in OSAHS patients with upper airway obstruction, and provide the basis for the individual treatment of patients with OSAHS.
