Objective To investigate the expression and clinical value of immunohistochemistry in endometrial stromal tumors.Methods Immunohistochemical technique(Envision method)was applied to de- tect the expression of CD_(10),SM-MHC,h-caldesmon,AE1/3,CD_(99),Ki-67,CD_(34),c-kit,ER and PR in 15 cases of endomertrial stromal sarcoma and 3 metastases.The clinical pathological data,including the histological characteristics,histochemical and immunohistochemical staining features,complication,differential diagnosis and prognosis of endometrial stromal tumours were analyzed.Results Among the 18 cases of endometrial stromal tumor,17 cases had shown positive for CD_(10),including 13 cases diffuse positive and 4 muitifocal,7 cases with smooth muscle differentiation,3 cases with epithelial differentiation,7 cases with sex-cord differ- entiation.13 cases of ER and 16 cases of PR were positive expression in endometrial stromal sarcoma.Ki-67 in range 36 %～78 %.Conclusion Endometrial stromal tumour can display multi-differentiation.They show various pathomorphological features,Smooth muscle and sex-coed differentiation,the most common types. CD_(10) can be expressed consistently in endometrial stromal tumors.CD_(10) with h-caldesmon and SM-MHC can be used to make differential diagnosis between the endometrial stromal tumors and cellular leiomy0ma.ER and PR should be routinely estimated and be a prognostic predictor for endometrial stromal sarcoma.

OBJECTIVETo investigate the association between CYP1A1 gene polymorphisms and susceptibility of nasopharyngeal carcinoma in Cantonese nuclear families through family-based association study.

METHODSA total of 457 Cantonese nuclear families,consisting of 2134 members, were recruited as subjects. Each family included two parents and at least one offspring with nasopharyngeal carcinoma. Two single nucleotide polymorphisms (SNP) in CYP1A1 named m1 (rs4646903) and m2 (rs1048943), were genotyped by PCR-RFLP assay and verified by directly sequencing. The genotype data were analyzed with family-based association test (FBAT) software to check the linkage and association between the two genetic markers and susceptibility of nasopharyngeal carcinoma.

RESULTSFBAT analysis showed that the minor allele frequencies (MAF) of the two SNP were 0.442 (C) and 0.339 (G) respectively. For m1 polymorphism in CYP1A1 gene was not significantly associated with nasopharyngeal carcinoma in our study population whether stratified with VCA-IgA or not (without stratification: chi2 = 2.399, P = 0.301; with stratification: low-titer group (VCA-IgA <1:80), MAF = 0.457 (C), chi2 = 1.221, P = 0.543; high-titer group (VCA-IgA > or = 1:80), MAF = 0.427 (C), chi2 =2.832, P = 0.243) . For m2 polymorphism, when VCA-IgA <1:80, the G allele showed decreased transmission under additive and dominant model (MAF = 0.347 (G); Zadditive = -2.120, Padditive = 0.034; Zdominant = - 2.303, Pdominant = 0.021) and a boundary P value was got with global statistic (chi2 = 5.394, P = 0.067) . Haplotype TG (0.057), constructed by m1 and m2, might decrease nasopharyngeal carcinoma risk (Z= -2.002, P=0.045). A boundary P value was also got with global statistic (chi2 =7.067, P=0.070).

CONCLUSIONThere was no statistical significance between m1 polymorphism and susceptibility of nasopharyngeal carcinoma in Cantonese nuclear families. And this study showed that m2 polymorphism might associated with the decrease of nasopharyngeal carcinoma in Cantonese nuclear families.

OBJECTIVETo investigate the scope and degree of short-term adverse reactions of peginterferon alfa-2a in treatment of chronic hepatitis in adults and children to provide basis for anti-viral treatment in clinical practice.

METHODSA prospective study was conducted in adults and children with chronic hepatitis treated with peginterferon alfa-2a. Meanwhile, the reactions in the patients were recorded with a table designed by ourselves and statistically analyzed.

RESULTSThe short-term adverse reactions included increase in body temperature and aching pain in joints and muscles. The increase in body temperature was the major reaction and accounted for 54.11%. The increase in body temperature began to appear in 47.6% of the patients. The body temperature was 37.3 degrees C-38.9 degrees C in most of the patients and mediate and low increase was found in 85.4% of the patients, which was decreased to 70% in the 4th week. However, the percentage of patients with high temperature was increased from 14.5% in the 1st week to 30% in the 4th week. The increase of body temperature began to appear in 9-12 h and 3-5 h after injection of peginterferon alfa-2a in the 1st and later, respectively. The duration of fever was 3-4 h in most of the patients. It appeared once in 1 week after the rejection in most of the patients. For management of fever, cooling with medication was conducted in 45.5 % of the patients.

CONCLUSIONThe short-term adverse reactions in patients with chronic hepatitis treated with peginterferon alfa-2a include the increase in body temperature etc. The severity of the adverse reactions gradually reduces with continuation of the treatment. Of the adverse reactions, the increase in body temperature is the major (47.6%) and others only account for 1%-16.9%. The increase in body temperature is mainly transient and no management is needed in 50% of the patients. Since the "ladder-type" dose-adding method is used for administration of peginterferon alfa-2a in this group of patients, the adverse reactions are low in number and mild in degree.
