Objective To explore the clinical manifestation,imaging features and treatment of primary lacri-mal gland epithelial tumor.Methods The clinical data of 25 cases with primary lacrimal gland epithelial tumors were retrospectively studied.Results All of 25 primary lacrimal gland epithelial tumor cases received surgical treatment. Fourteen primary orbital tumors cases were male and 11 cases were female.The mean age was 44 years old (ranged 23 to 65).The mean hospital stay was 12d(ranged 7 to 20).Among 25 primary lacrimal gland epithelial tumor cases, 11 cases were benign tumors which included 4 inflammatory pseudotumor,11 pleomorphic adenoma.Fourteen cases were malignant tumors which included 4 malignant pleomorphic adenoma,6 adenoid cystic carcinoma and 4 adenocar-cinoma.After opeation,visual acuity improved in 9 cases,unchanged 10 cases,decreased 6 cases.The patients were followed up for 16 -48 months(mean 27 months).There were 4 malignant tumors recurrence after operation and received radical operation.While 2 patients were lost and 2 patients died of tumor metastasis,the other 21 patients survived with tumor -free.Conclusion Primary lacrimal gland epithelial tumors have different clinical and imaging appearances.Combination of ultrasound,CT and MRI is important to ascertain the character,range and degree of primary lacrimal gland epithelial tumors.Surgical excision is the main and effective treatment for primary lacrimal gland epithelial tumors,while gamma knife treatment is safe and effective for malignant,unresectable,recurrences tumors.

Objective To analyse the lung function parameters of the patients with chronic obstructive pulmonary disease (COPD) to explore the clinical significance of lung function in the diagnosis and evaluation of COPD. Methods The lung function of 558 patients with COPD from January 2000 to April 2003 in our hospital was retrospectively analysed by using SPSS 10 0 software. Results The average ages of the 558 patients were 57 6?9 7 years, 78 9% of which were male. Patients with grades Ⅱ and Ⅲ COPD accounted for 70 2%. There was a negative relationship between FEV 1, FEV 1/FVC and smoking index(r=-0 039,-0 305,P

Objective To study the standardization of medical records writing by residents in hospitals. Methods With both quantitative and qualitative analysis, medical records made by residents were sampled in groups to study their standardization. Results Recognition rate of such medical records was 82. 55%, and the excellence rate was 24. 50% in the grade evaluation. For senior residents, their rate of writing excellence falls below those of junior ones; whether the evaluators have medical background bears no significant difference for grade evaluation of medical records writing, yet a significant difference was found with the recognition rate. Conclusion Writing of medical records by residents is found with incompliance now and then, and the recognition rate ought to be improved.

AIM: To study the relation between development of coronary collaterals and clinical outcome in patients with acute coronary syndrome(ACS).METHODS:251 patients with clinical diagnosed ACS were consecutively enrolled into the present study and divided into two groups according to the presence of coronary collaterals by quantitative coronary angiography(QCA).Serial venous blood samples were collected at admission for determining of high-sensitive C-reactive protein(hs-CRP),brain natriuretic peptide(BNP),and cardiac troponin I(cTnI).Baseline left ventricular ejection fraction(LVEF)was determined by cardiac echo.RESTULTS: Coronary collaterals were detected in 38 patients(as CC group),another 213 patients without coronary collaterals were served as control group.Serum levels of cTnI in patients in CC group was significantly higher than in control group((0.91)?(1.13) vs(0.29)?(0.23)(ng?ml~(-1)),P(0.05)).Serum levels of cTnI in patiemets of CC group was significantly lower than those of control group((0.29)?(0.23) vs(0.91)?(1.13)(ng?ml~(-1)),P

Objective To compare the long-term prognosis of patients with stage Ⅰ endometrial cancer (EMC) after laparoscopic surgery or open laparotomy. Methods Totally 83 patients with stage Ⅰ EMC who underwent laparoscopic surgery or open laparotomy between 1993 and 2008 were enrolled in this study. The clinical data were analyzed retrospectively to compare the survival time during long-term follow-up between the two groups. Results The total survival rate was 95.2% (79/83) in the 83 cases. The median survival time was 77,51,and 31 months respectively in stages Ⅰa,Ⅰb,and Ⅰc EMC patients. No significant difference was found in the survival rate between open and laparoscopy groups [94.2% (49/52) vs 96.8% (30/31),Z=0.028,P=0.978]. For the stage Ⅰa,stages Ⅰb and Ⅰc,and G2 and G3 patients,the median survival time was similar between the open and laparoscopy groups (80 month vs 63 months,P=0.483; 49 months vs 48 months,P=0.781; and 51 months vs 49 months,P=0.635). However,in the G1 patients,significantly difference was detected in the median survival time between the two groups (77 vs 51 months,P=0.037). Conclusion Laparoscopic surgery should be used as a routine surgical approach for patients with stage Ⅰ EMC considering its minimal invasiveness and promising prognosis.

OBJECTIVETo investigate the permance index ofof portable X-ray fluorescence spectrometer in the determination of lead on filter membrane and to provide data for the determination of lead in workplace air.

METHODSIrradiated with X-ray, the lead would emit specific X-ray fluorescence during the process from the excited state back to the ground state. Rapid determination of lead was completed using fluorescence energy and wave length for qualitative analysis and fluorescence intensity for quantitative measurement. Under set conditions, a series of customized calibration samples were measured to create a standard curve for quantitative analysis of lead on filter membrane.

RESULTSThe regression equation obtained using a portable X-ray fluorescence spectrometer to determine the lead on filter membrane was y=0.004x-0.182 (r2= 0.9999). The linear range was 0.00 -10.40 mg/m3, the minimum detectable concentration was 0.53 µg/m3, and the minimum quantifiable concentration was 1.76µg/m3. The relative standard deviation (RSD) of within-run precision of samples with different concentrations was 0.48%-6.22%, the RSD of between-run precision was 2.51%-5.09%, and the degree of accuracy was in the calibration range of standard samples.

CONCLUSIONPortable X-ray fluorescence spectrometry is a simple, rapid, repeatable, and accurate method for the determination of lead on filter membrane.
