Objective To identify the clinical features and risk factors of rheumatoid arthritis-associated interstitial lung disease (RA-ILD).Methods The clinical and laboratory data of 595 patients with RA hospitalized in Chaoyang Hospital.550 cases of patients were performed pulmonary high-resolution CT examination.Risk factors were analyzed with logystic regression analysis.Results ① There were 237 (39.8%)patients with RA-ILD.13.5% of RA-ILD occurred before the dia-gnosis of RA,69.7% of RA-ILD occurred within ten years after the diagnosis of RA,16.8% of RA-ILD occurred more than ten years after the diagnosis of RA.② The most common manifestations of HRCT were reticular opacity (57.8%),pleural thickening (57%),ground-glass opacity (53.2%),followed by septal thicke-ning,nodules,bullae,cellular-like changes and bronchiectasis.③ Pleural disease,bronchiectasis,pulmonary hypertension in RA patients were associated with RA-ILD.④ Compared with the RA-N-ILD patients,RA-ILD patients had a higher proportion of male patients,higher rate of smoking,older mean age at onset,shorter duration,more swollen joints higher levels of lactate dehydrogenase,globulin,erythrocyte sedimentation,C-reactive protein and rheumatoid factor,the difference was statistically significant (P<0.05).The forced vital capacity,forced expiratory volume in one second,carbon monoxide diffusion rate was lower,the difference was statistically significant (P<0.05).Logistic regression analysis showed that age,smoking,elevated lactate dehydrogenase,RF-positive rate were relevant factors of RA-ILD.Conclusion ILD is common in RA,and most of it occurrs within ten years after the diagnosis of RA,and often coexists with other lung disease.Age,smoking,elevated lactate dehydrogenase,RF-positive rate

Objective To investigate the expression of CD147 and its significance in human cervical carcinoma. Methods Western blotting and immunohistochemical staining were used to detect CD147 expression in cervical cancer or normal cervix uteri tissues. Results CD147 protein was expressed in all of cervical carcinomas (41/41, 100.0%) and most of normal cervix uteri tissues (11/12, 91.7%). CD147 with different molecular weights were present in cervical tissues. The percentage of CD147-positive cells and the expressional level of CD147 were higher in cervical carcinomas than in normal cervix (P<0.05). Conclusion CD147 might be recognized as a marker of cell proliferation. High expression of CD147 in cervical carcinomas suggests that it might be a potential target for cervical carcinoma therapy.

Objective To explore a method to improve the nutritional state and immune function of patients after radical gastrectomy,and to decrease postoperative complication rate and accelerate recovery from operation.Methods In line with the concept of fast tract surgery (FTS),a new perioperative nutritional schedule was made for patients prior to radical gastrectomy,ehich included preoperative nutritional risk screen and prophylactic enteral nutrition,early postoperative light enteral nutrition,early ambulation and perioperative nursing care.Patients with gastric cancer were randomly assigned into fast track group or a simple control group.New perioperative schedule was executed in the patients of fast track group and traditional nutrition support in control group.After operation,serum albumen was measured to evaluate the patient's nutritional state and serum IgA to evaluate gastrointestinal immune function.In addition,the time to passage of flatus,postoperative recovery time and complication rate after operation were compared.Results Patiens in FTS group (n=35) showed higher serum albumin and serum IgA on d1 and d3 after operation than those in the control group (n=25) (P

Objective To evaluate the effect of laparoscopy in treatment of renal cysts.Methods Twenty- eight and thirty-five patients with renal cysts were performed with transperituneal and retroperitonel laparoscopy,re- spectively.Results A total of 62 patients were treated successfully,the average operation time was 60 minutes,no complications presented,and there was no recurrence in follow-up.Conclusion Laparoseopy survey had the advan- tages of less trauma and fewer complications and rapid recovery in treatment of renal cysts,which was suggested for clinical applications.

The cortexes were obtained from new-born rats and dissociated to single cells by triturating. The cells were cultured in neural stem cell (NSC) culture medium (DMEM supplemented with bFGF, EGF and B27) and formed primary neurospheres after 7 days. Single cells dissociated from neurosphere were cultured in 96-well plates and formed single-cell cloning neurosphere 7 days later. The primary and single-cell cloning neurospheres were both positive for the immunofluorescent staining of nestin and were identified as NSC. It was proved that NSC can be expanded in vitro and provide seed cells for neural tissue engineering.

Objective To explore rapamycin's inhibitory effect on proliferation of H_(22) hepatic cancer in mice. Methods In vitro study: H_(22) hepatic cancer cell lines were cultured with rapamycin, CsA, FK506, and proliferation was determined through MTT. The influences of different agents on the H_(22) hepatic cancer cell cycle were observed by flow cytometry. The vascular endothelial growth factor (VEGF) concentration of the supernatant fluid of the cultured H_(22) hepatic cancer cell was detected by ELISA. In vivo study: C57BL/6 to Balb/c mice allogenic skin transplant was established, and the H_(22) hepatic cancer cell was implanted under skin. Rapamycin, CsA, FK506 and 5-FU were fed to the mice, respectively. The effect of different immunosuppressors on the survival of skin graft was observed while the proliferation of the transplant tumor was investigated. VEGF concentration of treated mice serum was examined by ELISA. The microvessel density of the transplanted tumor was observed through immunohistochemistry staining of CD34. Results The proliferation of the H_(22) hepatic cancer cells was inhibited by rapamycin at the concentration different dose of rapamycin, the VEGF concentration of the supernatant fluid decreased significantly (P<0.05). The number of S phase cells decreased significantly compared to that of other agents (P<0.05). When rapamycin, the lengthened survival time of the skin grafts was similar to that in CsA and FK506 groups. But the tumor volume was smaller than that in CsA and FK506 groups (P<0.05). Compared to that in the control group, the VEGF concentration of mice serum decreased in rapamycin group (P<0.05), and the microvessel density of the transplant tumor was reduced greatly (P<0.05). Conclusion Rapamycin, as an immunosuppressor, significantly resists immunologic rejection and inhibits the proliferation of H_(22) hepatic cancer, thus having its advantage in treating malignant hepatic cancer with liver transplantation.

AIM: To confirm the effects of capillary endothelium injury in the lung with ischemia reperfusion. METHODS: The rabbits pulmonary models of ischemia reperfusion (I-R)injury were established. Plasma nitric oxide and endothelin levels, arterial oxygen tension and wet/dry weight ratios were determined in different periods in control and I-R groups, and the pulmonary ultrastructure abnormities were analyzed under electromicroscope. RESULTS: The plasma levels of NO and ET-1 in I-R animals increased significantly ,compared with those in sham treated control groups. The level of ET-1 had significantly negative correlation with PaO 2 and positive correlation with the value of the wet/dry weight ratios. The swelling and karyopyknosis of capillary endothelium in the lung with I-R groups were observed in ischemia periods. The injuries of endotheliums and typeⅠandⅡ alveolar cells in 0 5 h of reperfusion were more severe than those in ischemia time, and the injuries began to repair in 2 h of reperfusion time. CONCLUSION: In the I-R group, pulmonary capillary endothelium have been injuried, which may play a prominent role in I-R injury and dysfunction of the lung.
