Objective To discuss the value of CT prognosis on the Masaoka staging system of thymic epithelial tumors(TET) before surgical resection.Methods The CT images of 102 patients with TET proved by surgery and pathology were reviewed retrospectively.The TET were reclassified according to Masaoka stage system.The size,homogeneity,sharp,contour,infiltration of surrounding tissue,and metastasis on CT were analyzed with Logistic analysis.The diagnostic value was also evaluated with a ROC curve.Results Masaoka pathologic stages were stage Ⅰ for 36 (35.3 %),stage Ⅱ for 27 (26.5 %),stage Ⅲ for 30 (29.4 %),and stage Ⅳ for 9 (8.8 %).A multivariable Logistic regression model showed that TET with larger size of tumor (20/35,P =0.0371,OR =4.539),irregular or lobulated tumor contour (26/42,P =0.0230,OR =4.870),heterogeneous (21/33,P =0.0154,OR =6.020),infiltration of surrounding fat (25/32,P =0.0019,OR =14.005),and pleural seeding (11/11,P =0.0032,OR =36.153)were more likely to have stage Ⅲ or Ⅳ disease.The area under ROC curve was 0.940.Conclusions The tumor CT imaging features can differentiate between stage Ⅰ,Ⅱ and stage Ⅲ,Ⅳ disease.This helps identified patients more likely to benefit from neoadjuvant therapy.

Objective To develop a suicide ideation scale for Chinese military.Methods Based on the analysis of literatures and the established ideation scale, the theory structure of suicide ideation scale was constructed and a scale was developed regarding to the results of specialists evaluation.Then 900 soldiers including navy, army and air force were picked out randomly as samples from a military region.The data Was submitted to factor analysis and to test the reliability and validity of the scale.Results The whole suicide ideation scale Was constitute of three factors, such as despair, depression and optimism.Correlation coefficient between each factor and the total score ranged from 0.679 to 0.913,Correlation coefficient between the scale and Suicidal Possibility Scale Was 0.620,the coefficient of stability was 0.904.the Cronbaeh α of each factor ranged from 0.750~0.894.Conclusion The scale proves to be applicable to Chinese military in evaluating their suicidal ideation.

Objective To improve clinicians' understanding of tuberculosis as the adverse event of the tumor necrosis factor alpha (TNF-α) antagonists therapy. Methods Two rheumatoid arthritis (RA) patients were reported to develop lymphoid tuberculosis and pulmonary tuberculoma after TNF-α antagonists therapy. The relevant literature were reviewed. Results The first ease was a 62 year-old female RA patient. Her skin PPD reaction was negative and chest X-ray was normal before the therapy. Following 4 doses of infliximab injection (each dose of 3 mg/kg) which were completed within 3 months, the patient developed fight supraclavicular lymphoids tuberculosis in the 5th month after the last treatment. The patient completely recovered after lymphoids excision and antituberculosis therapy with 4 anti-tuberculosis medications combination. The second case was a 44 year-old female RA patient. She did not take the skin PPD test and chest X-ray before the therapy. The patient developed fever and chest distress after etanercept therapy (25 mg hypodermic twice per week ) for 1.5 months. The chest X-ray showed a shadow in the median lobe of the right lung, which had gradually developed to a pulmonary tuberculoma. The patient's physical condition improved after the tubereuloma resection. It has been reported in recent years that ① TNF-α antagonists therapy could increase the incidence of tuberculosis, ② the incidence at which infliximab associated tuberculosis was higher than etanercept, ③ the majority of the patient having tuberculosis were old people, and ④ the incidence of extrapulmonary tuberculosis and the disseminated tuberculosis were higher than regular tuberculosis. Conclusion TNF-α antagonists may decrease the host defense ability against mycobacterium tuberculosis and increase the incidence of tuberculosis. The pre-treatment tuberculosis screening, as well as tuberculosis monitoring during and after treatment is mandatory.

OBJECTIVE: To investigate and analyze the storage temperatures of drugs for references of drug storage. METHODS: A classified statistical analysis was conducted on those drugs with temperature requirements in storage as instructed in drug package inserts. RESULTS: The stock drugs totaled 1 254 kinds,of which,483 (38.52%) had the item of temperature requirements in storage,158 with room temperature storage and 61 with cold storage had the item of specific temperature requirement. CONCLUSION: The storage temperature of drugs should be established based on the quality of different drugs so as to ensure the stability of drug quality. It is advisable to clarify the storage temperature in all the drug package inserts.

Objective To evaluate the epidemic status of main non-communicable chronic diseases among the residents of Jingan district in Shanghai.Methods Multistage cluster sampling was adopted.960 residents were investigated with questionnaire and physical examination.Results The prevalence rates of Hypertension,diabetes mellitus,Cerebral vessels and Heart-blood were 25.6%,5.8%,3.1%and 5.7%,respectively.The multivarate logistic regression analysis showed that the related risk factors to four non-communicable chronic diseases included family history,the OR(95%CI)1.6(1.2~2.3),6.9 (3.5~13.6),4.5(2.0~10.0),2.2(1.2~4.0)separately.Conclusion Hypertension,diabetes are the main non-communicable disease hazarding the public health.The government and professional institutes should raise the attention on this serious problem and finance more as well as supplying policy support.

To confirm the existence of heme oxygenase (HO)- carbon monoxide (CO)- cyclic guanosine monophosphate (cGMP) pathway in the cultured human trabecular meshwork cells (HT-MCs) in vitro, and to evaluate the inductive role of hemin on this pathway, HTMCs of the third to fourth generation were cultured in vitro. Reverse transcripase-polymerase chain reaction (RT-PCR) was employed for detection of HO-1 and HO-2 mRNA. Immunohistochemical staining was used to detect HO-1 and HO-2 proteins. Hemin was added into the culture solution. The HO-1 mRNA levels were quantified by RT-PCR. The relative amount of carbon monoxide released into the media was measured with the quantifying carbon monoxide hemoglobin (HbCO) by spectrophotometry. Radioimmunoassay was used to determine changes of cGMP in HTMCs. The results showed that cultured cells had the specific characteristics of HTMCs. Both HO-1 and HO-2 genes were expressed in HTMCs, as well as HO-1 and HO-2 proteins in HTMCs. Hemin induced HO-1 mRNA, HbCO and cGMP in a dose-dependent manner. In conclusion, HO-CO-cGMP pathway exists in the cultured HTMCs and can be induced by hemin. Pharmacological stimulation of HO-CO-cGMP pathway may constitute a novel therapeutic approach to rescuing glaucoma.
