Objective To analyze the efficacy,late complications and prognostic factors of post-op-erative radiotherapy for cervical cancer. Methods From Nov. 1999 to Feb. 2005,114 patients with cervi-cal cancer received adjuvant pelvic radiotherapy after radical hysterectomy and pelvic lymphadenectomy. The median age was 42.5 (24 to 72) years old. According to the FIGO staging system,6,51,18,26 and 13 pa-tients had stage ⅠA, Ⅰb1, Ⅰb2, ⅡA and ⅡBdisease. The pathological type was squamous cell carcinoma,ade-nocarcinoma, squamous-adenocarcinoma and undifferentiated carcinoma in 92,19,2 and 1 patients, respec-tively. The whole-pelvic external beam irradiation of 50 Gy (40 to 60 Gy) was given with 6 MV or 15 MV X-ray beams using four-field box technique. Eighty-one patients received intravaginal brachytherapy of 16 Gy (4 -30 Gy in 1 -6 fractions) 4 weeks after the beginning of radiotherapy, with the referrence point being at 0.5 cm under the vaginal mucosa. Eighty-seven patients received preoperative and/or concurrent chemother-apy. The survival and independent prognostic factors were analyzed by Log-rank method and Cox model. Results The median follow-up time was 26.0 (5 - 75) months. The overall survival rate, disease-free sur-rival rate and local control rate were 93.1%, 88.1% and 94.6% at 2-year, and 75.7%, 62.3% and 85.6% at 5-year,respectively. The independent prognostic factors were lymph node metastasis and positive surgical margin for overall survival, positive surgical margin for local control, and stage, uterine body invasion and positive surgical margin for disease-free survival. Sixteen patients ( 14% ) had distant metastasis, and the most common sites were the lung,inguinal region,bone,liver and brain. According to RTOG grading sys-tem, the incidence of late gastrointestinal side effects of grade 1,2 and 3 was 11.4%, 11.4% and 3.5%. The corresponding genitourinary side effects were 14.0% ,6.1% and 0.9%, respectively. The incidence of leg lymphedema was 7 % . Conclusions Post - operative radiotherapy can achieve good local control in cervical cancer with acceptable late side effects. Distant metastasis is the main cause of death.

Objective To judge method performance of routine biochemistry parameters on Roche Modular PPI testing system by using westgard's method evaluation decision chart.Methods We assessed imprecision(CV)from internal quality control and inaccuracy(bias)from external quality control evaluation.Combined estimates of imprecision and inaccuracy by plotting imprecision as the x-coordinate and inaccuracy as the y-coordinate to locate an expected operating point of every item on the chart.By comparing this operating point with allowable total errors(TEa),we can decide whether the performance is acceptable or not.Results In the 27 different parameters tested,imprecision and bias of calcium were 0.08 mmol/L and 0.06 mmol/L respectively,its performance was marginal.The imprecision of creatinine,urea,glucose, sodium,chloride and phosphorus were 3.20%,2.13%,1.52%,0.89 mmol/L,1.10% and 1.55%,the bias were 4.79%,0.96%,4.63%,0.80 mmol/L,1.74% and 4.13% respectively,their performance was good.M1 other 20 items were of excellence performance.Conclusions Routine biochemistry parameters on Roche Modular PPI testing system possessed good precision and accuracy,and their performance were acceptable.To judge method performance of biochemistry testing system by using westgard' s method evaluation decision chart was easy to do and suited for clinical laboratory.

Objective：A retrospective study was conducted to evaluate the efficiency of postoperative radiotherapy for completely resected, pathologically Stage Ⅲ a (N2) non-small cell lung cancer (NSCLC). Methods：From January 1989 to December 1993, among the patients with NSCLC who underwent radical surgery in the authors’hospital, there were 119 patients with completely resected, pathologically Stage Ⅲ a(N2)NSCLC. A total of 55 cases of these patients received postoperative radiotherapy with dose of 46-62 gray in mediastinum and hilus (S＋ RT group), except other 64 cases (S group). The survival rates and local control rates were analyzed and compared by the life table and Log-rank. Results：The clinical characters of patients such as age, sex, pathologic type were similar between two groups. The 1,3,5-year survival rates were 80.0％ , 32.7％ , 25.5％ respectively in S＋ RT group and 76.4％ , 36.4％ , 23.0％ respectively in S group, with no significant difference between two groups（ P >0.05） . The median time of local recurrence was 21 months in S＋ RT group and 12 months in S group, with significant difference between two groups(P<0.05） . The 1,3,5-year local control rates were 94.0％ , 78.5％ , 69.0％ respectively in S＋ RT group in contrast to 83.1％ , 58.3％ , 50.6％ respectively in S group(P< 0.05). The metastasis rates were similar in two groups （ P>0.05） . Conclusion：Postoperative radiotherapy can increase the local control rates and prolong the time of local recurrence for the patients with completely resected, pathologically Stage Ⅲ a (N2) NSCLC, but the survival rate can not be improved.

Objective To discuss the correlation between behavior characteristics and psychological condition of chronic type B hepatitis patients and analyze the effect of behavior characters to psychological condition. Methods 100 patients with type B hepatitis were investigated with symptom checklist (SCL-90) and type C behavior measuring scale (CB) and the data was analyzed. Results The patients with first third score in SCL-90 were enrolled in higher psychological condition group and patients with last third score in SCL-90 were enrolled in lower psychological condition group. Anxiety, depression, anger and anger extraversion in the two groups were compared and have significant differences ( P ＜ 0. 05). Anger and anger extraversion in type CB scale were positively correlated with all the factors in SCL-90. Anger measuring scale was positively correlated with the factors of constraint, interpersonal relation, depression, hostility and psychosis ( r =0. 245, 0. 233, 0.234, 0. 582, 0. 247 ; P ＜ 0. 05 ). Anger extraversion was positively correlated with the factors of constraint,interpersonal relation, hostility and psychosis ( r =0. 266, 0. 245, 0. 364, 0. 287 ; P ＜ 0. 05 ). The factor of optimistic was negative correlated with all the factors in SCL-90 especially with the factor of dread (P ＜0. 05).Conclusions The behavior characteristics had significant effects on psychological condition in chronic type B hepatitis patients.

OBJECTIVETo explore the association between angiotensin-converting enzyme (ACE) and the polymorphisms of N5, N10-methylenetetrahydrofolic acid reductase (MTHFR) gene in patients with ischemic stroke (IS).

METHODSTotally 454 patients with IS (IS group) and 334 controls (control group) were recruited in our study. Their I/D polymorphisms of ACE gene and C677T polymorphisms of MTHFR gene were detected by PCR and denaturing high performance liquid chromatography.

RESULTSThe frequencies of DD, ID, II and CC, CT, TT genotype in IS group were 22.5%, 43.4%, 34.1%, and 51.8%, 40.5%, 7.7%, respectively, and were 17.4%, 45.5%, 37.1% and 56.9%, 38.3%, 4.8% in the control group, respectively. DD genotype was associated with large-artery atherosclerosis (LAA), and TT genotype and T allele were associated with LAA and cardioembolism. Synergistic effects were found between TT and DD/ID DD genotypes in the pathogenesis of ischemic stroke.

CONCLUSIONDD, TT genotype and T allele are risk factors of IS, and ACE gene and MTHFR gene have synergistic effects in the pathogenesis of IS.

OBJECTIVETo analyze the associated risk factors, clinical characteristics and laboratory abnormalities of type 2 diabetes patients with fatty liver.

METHODSThe data of type 2 diabetes cases with fatty liver were collected in our hospital. 63 cases of type 2 diabetes without fatty liver were selected randomly as control during the same period. The associated variables were analyzed by using logistic regression model. The clinical data and liver function were compared between two groups.

RESULTSThe proportion of obesity and hyperlipidemia was higher in type 2 diabetes patients with fatty liver than without fatty liver. Body mass index (BMI) (OR: 4.392) was positive correlation to fatty liver in the patients with type 2 diabetes. In contrast, insulin sensitivity index (ISI) (OR: 0.000) and regular insulin treatment (OR: 0.058) were negative correlation to it. The abnormal frequencies of aspartate aminotransferase (AST, 16.0%), alanine aminotransferase (ALT, 25.2%), the ratio of AST/ALT less than 1 (52.8%) and gamma-glutamyltransferase (GGT, 31.9%) of type 2 diabetes patients with fatty liver were significantly higher than those without fatty liver (3.2%, 6.4%, 36.5% and 11.1% respectively).

CONCLUSIONObesity and insulin resistance might increase the risk of fatty liver in the patients with type 2 diabetes. Patients of type 2 diabetes with fatty liver show higher serum lipid level and more obvious damages of liver function than those without fatty liver
