Objective The aim of this study was to assess the clinical value of pro-gastrin releasing peptide (ProGRP) , squamous cell carcinoma antigen (SCC-Ag), cytokeratin 19 fragment antigen 21-1 (Cyfra21-1) and carcino-embryonic antigen (CEA) in the diagnosis and clinical stage of lung cancer in Chinese patients.Methods Patients with lung cancer and benign lesions confirmed by pathology were enrolled in Peking Union Medical College Hospital from January 2013 to October 2014.The serum levels of four tumor markers (ProGRP, SCC-Ag, Cyfra21-1 and CEA) were measured using immunoassays before treatment.The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and the areas under the receiver operating characteristic curve (AUCROC) of these four tumor biomarkers were analyzed for the diagnosis of lung cancer.Results A total of 134 patients were finally analyzed, including 73 patients with lung cancer and the other 61 patients with benign lung disease.The diagnostic sensitivity of serum Cyfra21-1 to lung cancer was 67.1％, the specificity 45.1％, the AUCROC 0.658.The diagnostic sensitivity of the panel including ProGPR, Cyfra21-1 and CEA to lung cancer was 75.3％ , the specificity 57.4％ , the AUCROC 0.702.In the lung cancer group, the AUCROC of ProGRP over 65 ng/L to diagnose small cell lung cancer was 0.954;the AUCROC of SCC-Ag over 1.5 μg/L to diagnose squamous cell lung cancer was 0.788;the AUCROC of Cyfra21-1 to diagnose non-squamous-non-small-cell lung cancer was 0.716.In small cell lung cancer patients, the level of ProGRP in limited-disease small cell lung cancer (LD-SCLC) were significantly higher than that in extensive-disease small cell lung cancer (ED-SCLC) (P =0.005).Conclusion This panel of serum tumor markers including ProGRP, Cyfra21-1 and CEA improves the diagnostic specificity and sensitivity in patients with high-risk lung cancer.The serum CEA level of advanced lung cancer patients is significantly increased.The high level of serum ProGRP predicts the ED-SCLC.

Objective To observe the clinical efficacy of wheat-sized moxibustion in treating epigastric pain due to deficient cold of spleen and stomach. Method Fifty-six patients were randomized into a treatment group and a control group, 28 cases in each group. The treatment group was intervened by wheat-sized moxibustion; the control group was by orally taking Omeprazole enteric-coated tablets. For both groups, 7 treatment sessions were taken as a course, and the therapeutic efficacies were evaluated after 2 courses. Result There were significant differences in comparing the total effective rate, pain score, and relapse rate between the two groups (P<0.05). Conclusion It can be confirmed that wheat-sized moxibustion is effective in treating epigastric pain due to deficient cold of spleen and stomach, and it can effectively lower the relapse rate and significantly reduce the sufferings brought by the recurred symptoms.

Objective To assess the efficacy of radical transurethral electrovaporization for invasive bladder cancer. Methods Thirty-six patients with invasive bladder cancer from february 2008 to February 2010 were treated by transurethral electrovaporization resection of bladder tumor (TURBT). The operation procedure was based upon the principle of radical transurethral resection for bladder tumor. The tumor was resected to fatty layer outside the bladder wall. After operation Bacillus Calmette-Guerin (BCG) irrigation of bladder was given,all patients were followed up for 3 to 24 months. Results The recurrence occurred in 12 cases in 2 years,with a recurrence rate of 33. 3% (12/36). These recurrence cases were treated with TURBT again. Six cases dead in 2 years,with a mortality of 16. 7% (6/36). Conclusion TURBT is suitable for those who are older or weak,and not medically fit for radical cystectomy or those who refuse the open surgery,which can prolong the survival time and improve the quality of life.

Objective To solve the new problems for quality assurance of PACS which imported by the use of PACS.Methods The medical imaging quality control system used between imaging modality and image acquisition gateway was designed.Results The medical imaging quality control system could partially solve the problem for quality assurance of PACS.Conclusion With the use of medical image quality control system,wrong or low quality image can be found and modified earlier.Therefore,the veracity of medical information and medical image of PACS can be improved farther.

Objective To analyze X-ray plain film and CT signs of giant cell tumor of bone.Methods Imaging findings of giant cell tumor in 53 cases proved surgically and pathologically were retrospectively analyzed.Results 39 cases appeared as expensive cystic and eccentric destruction,osteolytic destruction 14 cases.Bone crests were usually seen in (39/53).Most of lesions did not have bone septations on CT image.The borders of destructive bone were clear and existed complete or incomplete sclerotic borders in 19 on CT image.The inner soft tissues of lesions were heterogeneous in most of the cases.Fluid-fluid level could be seen in 11 cases.The soft tissue masses outside the bone were demonstrated in the majority cases with discontinuous bone shell.Conclusion CT is more helpful than X-ray plain films in diagnosis of giant cell tumor of bone.

OBJECTIVE To analyze 61 cases occupational exposure risk factors,the preventive measures and reduce occupational exposure risk.METHODS The record of 61 cases of occupational exposure such as job seniority,occupation,exposed location,place,method,damage degree,processing,preventive medicine and follow-up results register will be statisticully analysed according to the registered items from Jan 2007 to Dec 2008.RESULTS The factors of occupational exposuve were needle treatment,violating operution standard and deficient of protective measures.Both ward and hand were the main place of occupational exposure.CONCLUSIONS Strengthening of effective preventive measues is key to minimize the risk of occupational exposure and reduce the incidence of infection.

Objective To investigate the effect of RBP on 3T3-L1 adipocyte differentiation,lipid metabolism and glucose transporter 4(GLUT-4)gene expression.Methods We constructed an expression vector for rat resistin gene and transfected it into 3T3-L1 adipocytes.RBP was added to the medium of 3T3-L1 adipocytes or resistin-overexpressing adipocytes on day 0 of differentiation.Cell differentiation and lipid accumulation were determined by oil red O staining.The mRNA expressions of differentiation marker genes(pref-1,C/EBP?,FAS)and GLUT-4 gene were evaluated by RT-PCR.Triglyceride(TG)and free fatty acids(FFAs)in adipocytes were measured by colorimetric kit.Results(1)When 10-12mol/L RBP was applied,the percent of living cells was high and the shape was unchanged.(2)RBP had no effect on the differentiation of normal adipocytes,but significantly decreased the number of lipid droplets in resistin-overexpressing adipocytes without affecting the lipid droplets-presenting day.(3)C/EBP? and FAS expressions in resistin-overexpressing adipocytes were down-regulated after RBP was applied,without changing their expressions in normal adipocytes.(4)RBP had no effect on the cellular TG and FFAs levels in normal cells,whereas it can significantly decrease the levels in resistin-overexpressing adipocytes.(5)There was no difference in the expression of GLUT-4 gene between 3T3-L1 adipocytes and RBP-applied cells.Conclusions(1)RBP has no effect on the cell differentiation and lipid metabolism in normal 3T3-L1 adipocytes.(2)RBP can inhibit the cell differentiation and lipid metabolism of resistin-overexpressing 3T3-L1 cells.(3)RBP has no effect on the expression of GLUT-4 gene.

Objective To explore the relationship between the posterior circulation ischemia(PCI) and vertebrobasilar artery lesion.Methods 57 patients with PCI(PCI group) were examined by DCE-MRA for their craniocervical artery,and the results were compared with the stroke inpatients but non-PCI during the same period(non-PCI group).Results The abnormal rate of vertebrobasilar artery in PCI group(70.2%)was significantly higher than that in non-PCI group(50.7%)(P

Objective Percutaneous puncture of gasserian ganglion was guided by CT scan to improve the accuracy and reduce complications and to compare the efficacy of chemical mutilation with ethyl alcohol and adriamycin.Methods Ninety-two patients with primary trigeminal neuralgia (39 males, 53 females) aged 37-84 yrs were divided into two groups : A ethyl alcohol group ( n = 47) and B adriamycin group ( n = 45) . Secondary trigeminal neuralgia was excluded by preoperative CT scan. Percutaneous puncture of oval foramen was guided by CT and correct location of needle tip was confirmed by injection of contrast medium. 100% ethyl alcohol 0.5ml (group A) or 2% adriamycin 0.5ml was injected.Results The patients were followed up for 12 months after treatment. Neuralgia disappeared in 31 out of 47 patients in group A (alcohol group) and in 36 out of 45 patients in group B (adriomycin group) . Treatment failed in 13 patients in group A and 6 patients in group B, and was partly effective in the other patients. There were no severe side effects or complications. Conclusion Percutaneous puncture of gasserian ganglion guided by CT is effective and reduces complications. Adriamycin is more effective than ethyl alcohol for chemical mutilation.
