Cyclooxygenase (COX) is a crucial enzyme in the biosynthesis of prostaglandins.There are two COX isoforrns:COX-1 and COX-2.Recently it is demonstrated that there is a close relationship of COX-2 with the occurrence,development and metabasis of tumor; COX-2 inhibitor is hoping to be a new target in tumor therapy.The article overviews many progresses of COX-2 about its expression,modulation and mecha-nism of carcinogenesis in cholangiocarcinoma in order to explore the prospect of the COX-2 inhibitors in cholangioearcinoma treatment.

OBJECTIVETo study the relationship between Chinese medical syndrome types and metabolomics of non-small cell lung cancer (NSCLC) patients.

METHODSTotally 120 NSCLC patients were assigned to asthenia syndrome group and sthenia syndrome group, 60 in each group. Meanwhile, 60 cases of benign pulmonary nodules in physical examinations were recruited as the control group. Tumor tissues or benign pulmonary nodules tissues were obtained by thoracoscope. Changes of their metabolites were observed using gas chromatography-mass spectrometry (GC-MS). Their differences were studied using principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA). ROC curve analysis was performed in different metabolic compounds of sthenia and asthenia syndromes groups. The area under the curve (AUC) was calculated to evaluate the sensitivity of diagnosing syndrome types.

RESULTSCompared with the control group, difference existed in 16 compounds. Of them , contents of citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, linoleic acid, oleic acid, lactic acid, inositol were more in the two tumors group than in the control group. Difference existed in 10 compounds between the sthenia syndrome group and the asthenia syndrome group. Of them, citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, lactic acid, and inositol were more in the asthenia syndrome group than in the sthenia syndrome group. Contents of valine, glucose, and glutamine were more in the sthenia syndrome group than in the asthenia syndrome group. ROC curve analyses of different compounds indicated that AUC of lactic acid and glucose was more than 0.8 (P < 0.01); AUC of inositol, choline phosphate, and glycerol phosphate choline was more than 0.7 (P < 0.01); AUC of valine, citric acid, glutamine, alanine, and pyruvic acid was more than 0.6 (P < 0.05).

CONCLUSIONSThere existed certain correlation between CM syndrome types and metabolomics of lung cancer. Lactic acid, glucose, inositol, choline phosphate, glycerol phosphate choline, valine, citric acid, glutamine, alanine, pyruvic acid were sensitive diagnostic compounds, and the first four kinds were most sensitive compounds.

The hepatocellular carcinoma (HCC) is one of the most common malignant tumors.Patients with hepatobiliary cancer suffer from multiple symptoms,such as physical symptoms and psychology symptoms.In recent years,along with the further research of symptoms,the concept of symptom clusters occurred.Those two issues have always been the hot topics in recent years.Through the efforts of experts at home and abroad,there has been a part of progress in this area.However,the results are not the same.There are lots of disputes in the numbers、sequence、incidences of the symptom clusters.The paper will discuss this issue from symptom experience and symptom clusters in order to provide the reference and basis for symptom management.

AIM: To survey the pathogenesis, clinical characteristics and surgical treatment for the correction of A-pattern exotropia.METHODS: The case history and surgical effect of 62 A-pattern exotropia in 1825 strabismus were studied. The superior oblique muscles weakening or the horizontal muscles procedures were performed in all patients according to the dysfunction of the superior oblique muscles, horizontal deviation, with or without binocular vision. Follow-up after surgery was 6-18months with mean duration of 9 months.RESULTS: A-pattern exotropia accounts for 3.4% of all strabismus. A-pattern exotropia accounts for 21.2% of A-V syndrome. After surgery, 52 cases got alignment, 56 cases gained A-sign correction and 54 cases recovered binocular vision.CONCLUSION: A-pattern exotropia is a common type in strabismus, its etiology is mainly oblique muscle dysfunction.Different surgical procedures should be selected according to overaction degrees of oblique muscle and binocular vision function, which can acquire the satisfied results.

Objective To investigate the effect of gastrointestinal environment on fecal occult blood test.Methods Mixed peripheral venous blood (45 ml) of 25 healthy volunteers from medical examination center of China-Japan Friendship Hospital in 2015 were collected to establish an in vitro gastrointestinal digestion model.The model was used to study the effects of different digestion time and concentration of digestive juice on the immunochemical fecal occult blood test using two kinds of occult blood detection reagents.Results When the amount of bleeding was over 5 ml,fecal occult blood test still showed positive after artificial stomach liquid digestion for 2 hours and artificial intestinal liquid digestion for 5 hours.The fecal occult blood test turned negative after artificial stomach liquid digestion for 0.5-3 hours and artificial intestinal liquid digestion for 3 hours.The positive rate of fecal occult blood test was closely related to the amount of bleeding.When the amount of bleeding was large and bleeding was acute,false negative could be caused by postzone phenomenon.The upper detection limit of two reagents was more than 3 165 ng/L,and the lower detection limit was0.2 ng/L.Conclusions Higher positive rate was detected not only in lower digestive tract bleeding but also in upper gastrointestinal bleeding with immunoassay method.Immunochemical fecal occult blood reagent had a wide detection range and could meet the clinical requirements for detection of gastrointestinal bleeding.

Objective To explore the rehabilitation outcome and influencing factors of functional recovery in patients with nontraumatic spinal cord injury (NTSCI). Methods A retrospective analysis was done on 49 cases suffering from NTSCI who recepted rehabilitation therapy from December 2014 to November 2016. The main indicator of the rehabilitation effect was Modified Barthel Index (MBI). A total of 49 cases were divided into two groups, effective group (31 cases) and ineffective group (18 cases) according to whether their MBI on discharge had beated the target setted on admission. The following factors:ages, gender, injury causes, injury level, injury grade, injury severity, the types of paralysis, hospitalization time, sick time, complications number, MBI on admission and discharge, operation, early rehabilitation were evaluated by Univarite analysis and Logistic stepwise regression to assess how they influenced rehabilitation outcome. Results After systematically rehabilitation training, MBI had apparent improvement, from (38.98 ± 24.90) score on admission to (56.35 ± 22.69) score on discharge and had statistical significance(Z=-4.95, P=0.00), which showed that rehabilitation training can effectively improve patients′ self-care ability of daily living. Regression analysis found that the MBI on admission (OR=1.044, P=0.010) and hospitalization time(OR=1.044, P=0.039) had a noticeable effect on the rehabilitation outcome, while all the other factors, such as age, sex, injury grade, injury level, injury severity, complications number hadn′t show concrete effect on rehabilitation outcome. Conclusions Patients with NTSCI should have early rehabilitation, medical staff should assess their admission MBI, make a strict rehabilitation training plan to improve rehabilitation efficiency, shorten hospitalization time, improve the patients quality of life.
