Results The group of diabetic CHD had a significant higher frequency of C allele of the AT1 All66C gene than normal control (X2 = 6. 02,P＜0. 05) and diabetes (X2= 5. 71,P＜0. 05). Conclusion The result indicated that there was an association between the 1166C allele of the AT1 gene polymorphism and CHD in type 2 diabetes patients.

PURPOSE This paper studied the significance of the relationship between expression of CD44 adhesion molecules and tumor metastasis. METHODS The CD44 expression in metastatic adenocarcinomas 31 cases. Squa-mous-cell carcinomas 27 cases in nodes and primary nasopharyngeal carcinomas 39 cases with nodal metastasis were used. LSAB immunohistochemical staining of CD44 monoclonal antibody. RESULTS 1. The CD44 expression was found in nodal metastatic adenocarcinomas 18 cases (57%) and squamous-cell carcinomas 7 cases (26%). There was a notable difference between two groups of CD44 expression. But the lung squamous-cell carcinoma showed nodal metastasis in lung hilum higher than the adenocarcinoma. 2. The CD44 expression was present in primary nasopharyngeal carcinomas 11 cases (55%) and esophageal squamous-cell carcinomas 25 cases (64%) with nodal metastasis. There was no significant difference between the two groups. Based on our results and new references suggest that these is a close relationship between the CD44 expression and tumor meatstasis in numerous tumors. But these were not constant. CONCLUSION Therefore the CD44 expression can not be used as a univeral indicator in tumor metastasis.

The clinical effects were observed in the two groups. Results: The total effective rate was 93.3% in the treatment group and 80.0% in the control group. The therapeutic effect was significantly better in the treatment group than in the control group (P<0.05). Conclusion: Acupuncture plus cupping method has a good effect for chronic simple pharyngitis.

Objective To investigate the effect of Liuwei Dihuang decoction combined with Taohong Siwu decoction in the treatment of traumatic renal contusion and laceration with long time no absorption of hematoma.Methods 166 patients with traumatic renal contusion and laceration with long time no absorption of hematoma from the department of urinary surgery from June 2014 to July 2016 in our hospital were selected and divided into two groups,83 cases in the control group treated with routine conservative treatment,83 cases in the experiment group received Liuwei Dihuang decoction combined with Taohong Siwu decoction on the basis of the control group,hematoma absorption,the scope of the hematoma of the kidney,the hemodynamic parameters of renal artery,the level of serum inflammatory factors,and the clinical effect were compared after the treatment.Results After treatment,the effective rate in the experiment group 93.98% was higher than the control group 77.11% (P<0.05);Compared with the control group,the beginning of absorption time of kidney hematoma,disappearance time of microscopic hematuria and the hospitalization time were shorter in the experiment group after treatment, the scope of perirenal hematoma was smaller after 2,4,12 weeks of treatment,the levels of Vmax and Vmin in renal aorta were higher,levels of AT and RI were lower after treatment, serum levels of TNF-α, IL-8, IL-1, IL-6 were lower after treatmentwith significant difference ( P <0.05 ). Conclusion Liuwei Dihuang decoction combined with Taohong Siwu decoction can significantly promote the absorption of hematoma in patients with traumatic renal contusion and laceration,improve the blood flow of renal artery,reduce the inflammatory reaction index, promote the recovery of renal injury,shorten the length of hospital stay.

Objective To explore the MRI features of Langerhans cell histiocytosis (LCH) in central nervous system (CNS) in children. Methods Clinical and MRI data of 25 cases with LCH in CNS from three children's hospitals between January 2009 and December 2014 were retrospectively studied. All cases were confirmed by surgery or biopsy. All cases underwent non?contrast and contrast pituitary and/or cranial MRI examinations. The location, morphology, MRI signal and enhanced patterns of LCH lesions were observed and analyzed. Result A total of 17 cases had hypothalamic-pituitary LCH, with 2 of them complicated with pineal cyst, 2 complicated with brain parenchymal lesions, and one complicated with both pineal cyst and brain parenchymal lesions. MR images showed that neurohypophysis lost its original hyper?intensity on T1WI, and nodular or homogeneous thickening was seen in the pituitary stalks. Dura matter was involved in 3 cases, 2 of them had single lesion, and the other one got multiple lesions. Neoplasm in choroid plexus was seen in trigone of left lateral ventricles in one case. Three cases with pineal gland involved demonstrated cystic change. Four cases had gray matter involved, with cerebellar dentate nuclei involvement in 2 cases, and both thalamus and basal ganglia involvement in the other two cases. Three cases showed white matter involvement without obvious Virchow-Robin space enlargement and brain atrophy. Conclusions MR imaging of LCH in CNS shows certain specific characteristics. The diagnosis can be made comprehensively based on both clinic features and other imaging findings.

BACKGROUND: The use of bone graft materials can promote bone fusion and enhance the stability of the spine during the spinal fusion. OBJECTIVE: To investigate the effect of autologous bone marrow mesenchymal stem cel s with hydroxyapatite/ tricalcium phosphate in the spinal fusion. METHODS: A retrospective analysis of clinical data of 64 patients with spinal fusion was carried out, and these patients were divided into two groups (n=32 per group): control group undergoing autogenous iliac bone grafting and observation group undergoing autologous bone marrow mesenchymal stem cel s combined with hydroxyapatite/tricalcium phosphate. Al patients were fol owed up for 12 months, and their recovery conditions about low back pain, spinal fusion and vertebral reset were assessed. RESULTS AND CONCLUSION: The low-back outcome scale scores and excel ent rate, Lenke grading and Cobb angle had insignificant differences between the two groups after treatment (P > 0.05). No infection, inflammation and skin irritation occurred in the two groups. The coagulation function, renal function and inflammatory factor levels were at normal levels in al the patients, and there was no difference between the two groups (P > 0.05). These findings indicate that autologous bone marrow mesenchymal stem cel s combined with hydroxyapatite/tricalcium phosphate can achieve clinical outcomes equivalent to the autologous iliac bone grafting.

Drug dependence has been a hot topic in neuroscience research due to its complicated pathogenesis. Recently, huge scientific efforts have been continuously put into understanding the association between drug dependence and polymorphism in ATP-binding cassette subfamily B member 1 transporter ( ABCB1 ) gene, especially a mutation in exon 26 at position 3435 (3435C>T). This article reviews the relationship between opioid dependence and analgesic tolerance and ABCB1 gene pol-ymorphism, which will shed light on the underlying mechanisms of drug dependence and optimal MMT programs for individuals.

OBJECTIVE: To verify the relationship between THI and VAS scores in patients with sudden hearing loss and tinnitus in a prospective study. METHOD: Forty-four patients classified their tinnitus according to VAS and THI before and after treatment, and both scores were compared through the Pearson's correlation coefficient test and Nonparametric tests. RESULT: There was a correlation between VAS and THI scores in patients with sudden hearing loss and tinnitus. Tinnitus assessment scores were significantly reduced after treatment. Decreasing of THI and VAS scores were not depended on frequency and loudness of tinnitus and severity of deafness, but therapeutic effect of sudden sensorineural hearing loss. CONCLUSION THI and VAS scores are useful for assessment of tinnitus in patients with sudden hearing loss and tinnitus.
