Objective To investigate the relationship between the osteopontin ( OPN ) expression of colorectal cancer tissues with the clinical characteristics and prognosis. Methods The expressions of OPN in colorectal cancer tissues and their corresponding para-cancerous tissues from 112 cases of colorectal cancer patients were detccted by immunohistochemistry . The relationship between the expressions of OPN and the clinicopathological features in pait-ients with colorectal cancer were analyzed. Results The OPN expression of colorectal cancer tissues was signifi-cantly higher than their corresponding adjacent normal tissues, the difference was statistically significant ( P <0. 05). Its expression was significantly associated with tumor size, histological differentiation, TNM stage, tumor status. Disease-free survival, and overall survival time of OPN protein positive expression group were lower than that of the negative group, respectively, the differences were statistically significant(P<0. 05). The expression of OPN in colorectal cancer tissues was an independent prognostic factor. Conclusion The expression of OPN is sig-nificantly increased in colorectal cancer tissues, and the positive expression of OPN is associated with the prognostic of patients with colorectal cancer.

Objective To evaluate the treatment effects of double parabolic lingual springs appliance and straight wire appliance therapy in skeletal class Ⅲ malocclusion. Methods 12 cases with skeletal class Ⅲ malocclusion were treated by double parabolic lingual springs appliance and straight wire appliance, cephalometric tracing measurement were taken in analysis,compared between pretreatment and posttreatment in each case. Results The comparison of before and after orthodontic treatment showed angle SNA increased by 2.80°, angle SNB decreased 1.39°ANB decreased by 4.88°. Conclusion The above metioned technique could be a reliable way to treat mild and moderate skeletal class Ⅲ malocclusion.

Although choledochoscope has been described as an ideal approach for cholelithiasis, larger,impacted or residual biliary duct stones could hardly be taken out. Choledochoscopic laser lithotripsy was used in 1978. At present, however, it has not wildly been applied in the biliary surgery. In this article, we reviewed the domestic and foreign literatures to state the application and prospect of choledochoscope combined with laser lithotripsy in cholelithiasis.

Objective: To analyze the efficiency of chronic disease prevention and control of primary health service institutions in Shandong, and provide policy references. Methods:Using CRS and VRS models from DEA to analyze the representative input and output indicators in primary health Service institutions. Results: The overall efficiency of chronic disease prevention and control in primary health service institutions is low, and the actual output was insufficient compared with the target output. Conclusion: Strengthening chronic disease control measures in high-risk group and establishing management mechanism leaded by the goal of chronic prevention and control in order to achieve optimal allocation of resources.

An indexing system is constructed,based on the implementation of prevention and control technology for chronic non-communicable diseases in community health service institutions,using both literature review and Delphi method,and using the Analytic Hierarchy Process (AHP) to calculate the weight of the indexing system.The system comprises three level-1 indexes,8 level-2 indexes and 33 level-3 indexes.The research proposed a transition from emphasis of therapeutic means to prevention,and emphasis on prevention and control technologies to the high-risk population in the prevention and control technology of chronic non-communicable diseases,along with development of techniques and measures to encourage behavioral changes of the population with chronic diseases.

Objective To study the indoor air pollution characteristic and control countermeasure. Methods 10 office rooms and 100 houses that were newly redecorated for one month were chosen for the determination of formaldehyde, TVOC, ammonia and radon. The distribution characteristic of time, space of pollutants was studied. Results The concentrations of formaldehyde, TVOC, ammonia in the investigated office rooms exceeded the standard limits greatly, the average levels were 0.533, 5.57and 0.396 mg/m3 respectively. In the 100 houses, the rates of exceeding limit of formaldehyde, TVOC, ammonia were 35.0%-78.8%, 56.0%-75.0% and 37.0%-41.7% respectively. In the two kinds of sites, the concentration of radon did not exceed the limit. Along with ventilation, the concentrations of pollutants went down. Conclusion Indoor air pollution caused by redecoration is serious in a certain degree in Lanzhou.

Objective To evaluate the treatment outcome of nerve fascicle transfer for treatment of flexor elbow Method Fifty two cases of brachial plexus injury were involved The function of elbow joint was restored by using fascicle nerve transfer from part of median nerve, ulnar nerve, thoracodorsal nerve and contralateral C 7, to the muscular branch of the biceps Results There was no significant adverse effects of the donor function following partial nerve resection Twenty six patients had biceps strength M 4 and flexed elbow joint more than 90 degree Conclusion Partial nerve fascicle transfer to the nerve branches of biceps from the donor nerve can provide sufficient nerve fibers to reinnervate biceps

Objective To observe the effect of Yiqi Huaxian Decoction (YHD) on transforming growth factor ?1(TGF-?1 )mRNA expression in rats alveolar macrophages (AM) and pulmonary interstitial macrophages (IM).Methods Ninety-six Wistar rats were randomized into sham-operation group,model group,YHD (4 g?kg-1?d-1) group,and hydrocortisone (20 mg?kg-1?d-1) group.Bleomycin A5 was injected into the rats' trachea to induce pulmonary fibrosis.AM and IM were isolated for the culturing after modeling for 7 and 28 days.Molecular in-situ hybridization (ISH) was used for the detection of TGF-?1 expression in AM and IM.Results Percentage of cells in AM and IM with TGF-?1 positive expression and the score of optic density were increased in the model group (P
