Objective To study the clinical outcome of breast conserving treatment of breast ductal carcinoma in situ(DCIS).Methods The data of 62 patients with pathologically proven DCIS who underwent breast conserving operation and adjuvant radiotherapy were retrospectively compared with 62 concurrent cases of stageⅠ or Ⅱ infiltrating ducatl carcinoma who received breast conserving operation and adjuvant readotherapy.Results The recurrence rate in DCIS cases was 6.4%(4/62),among them,3 cases belonged to comedo type;the recurrence rate in early infiltrating type of ductal breast carcinoma was 19.3%(11/62)(P

Objective To establish an efficient HPLC method for the determination of uric acid in plasma of hyperuricemia model mice,and the evaluation of uric acid lowering effect of Lesinurad.Methods The Laballiance Series Ⅲ HPLC system was adopted with Kromasil C18 column (100 mm × 4.6 mm,5 μm).The mobile phase consisted of methanol-0.5％ acetic acid (10:90) for isocratic elution with a flow rate of 0.4 mL/min.The detection wavelength was set at 283 nm.The established HPLC method was used to detect the plasma uric acid level of mice at 0.5,1.0,and 2.0 h time points after which being ip injected with 250 and 500 mg/kg uric acid.Lesinurad of 250 and 500 mg/kg was ig given to mice,0.5 h later,mice were ip injected with 500 mg/kg uric acid to establish hyperuricemia model,and 1 h later,the established HPLC method was used to detect the plasma uric acid level of mice.Results There was a good linear relationship between peak area and the concentration of plasma uric acid in the range of 7.5-150 μg/mL (r =0.997).The specificity,repeatability,precision,stability,and recovery of the established HPLC method was in accordance with the guiding rules of biological sample determination.Compared with the endogenous serum uric acid concentration of control group mice,serum uric acid concentration of 250 mg/kg dose group was significantly increased 0.5 h after ip administration with uric acid (P ＜ 0.01),and serum uric acid concentration of 500 mg/kg dose group was significantly increased 0.5,1.0,and 2.0 h after ip administration with uric acid.Compared with model group,the concentration of uric acid in plasma decreased significantly in low dosage group administered with Lesinurad (P ＜ 0.05),while decreased more significantly in high dosage group (P ＜ 0.01).Conclusion This convenient,rapid,and accurate method can be applied to the determination of uric acid in mouse plasma and the evaluation of relative drugs,which provide an efficient analysis way for establishing hyperuricemia model and screening relative drugs.

ObjectiveTo study the scope of excison in breast-conserving surgery for breast carcinoma.MethodsClinical data of 275 breast cancer patients undergoing breast-conserving surgery in t he First Affiliated Hospital of Nanjing Medical University,the Affiliated Zhenjiang Hospital of Jiangsu University and Changzhou Traditional ChineseMedicine Hospital were retrospectively analyzed.The operation procedure and postoperative adjuvant therapy were carried out with the same protocol.Local and general conditions of patients were followed up regularly.Results271 out of 275 patients got follow-up.The follow-up rate was 98.5％.The follow-up time ranged from 1 month to 117 months,median follow-up time was 34 months.Six patients died of distant metastasis,2 with local recurrence.The 1-year,3-year,and 5-year overall survival rates were 99.5％,98.1％,and 95.7％,respectively.ConclusionsIt is safe to excise 1 cm normal breast tissue with clear margin confirmed by frozen section,followed by postoperative adjuvant therapy,endocrine therapy,and radiotherapy,this improves the life quality of patients with breast cancer.It is safe and effective to determine whether the disease is multicentric or multifocal by mammogram plus clinical breast examination.

Objective To investigate the rational method of treatment of rectal carcinoid and its outcome.Methods The clinical data of 36 cases of rectal carcinoid were retrospectively analysed.Results During a follow-up of 82.6+/-63.4 months,there were no cases with recurrence among the 20 patients with tumor size2cm.Conclusions Tumor diametar can be used to estimate the degree of malignancy of rectal carcinoid.TNM staging is simpler and practical for deciding the method of surgical treatment.

The purpose is to study the prophylactic and therapeutic effect of the traditional Chinese Medicine (TCM)-Jinyebaidu (JYBD) to guinea pig cytomegalovirus (GPCMV) intrauterine infection. The virus-free female and male guinea pigs were screened with nest-polymerase chain reaction (N-PCR). After inbred, pregnant guinea pigs were selected and divided into 3 groups randomly: 5 guniea pigs of the blank control group were not given either GPCMV or JYBD. 31 guniea pigs of the positive control group were inoculated 1 mL (10(7) TCID50) suspension of GPCMV intraperitoneal. 10 guniea pigs of the experimental group were inoculated GPCMV firstly and then perfused stomach with JYBD for 14 days (Dosage in accordance with the modulus of the weight ratio of human to guniea pig). The effects of JYBD on the intrauterine infection of GPCMV were observed. The results showed that JYBD could decrease the maternal infection rate from 100% (31/31) to 50% (5/10) (P < 0.001), the intrauterine infection rate from 100% (72/72) to 75% (21/28) (P < 0.001), and the rate of abnormal outcome of pregnancy from 64.4% (29/45) to 25.0% (7/28) (P < 0.001), the infective symptoms being relieved. It can be concluded that traditional Chinese medicine- JYBD can prevent and treat (GPCMV intrauterine infection, and can be expected a prophylactic drug for HCMV intrauterine infection.

Objective: The aim of this study was to evaluate the impact of fast track surgery on host cell-mediated immunology and inflammatory responses in colorectal cancer patients.Methods: Sixty colorectal cancer patients were prospectively divided into fast track surgery(FTS)group(n=30)and conventional perioperative care group(n=30).In addition to clinical parameters(recovery of gastrointestinal function,complication rates and postoperative length of stay), the parameters of perioperative cell-mediated immunology function,and the serum level changes of CRP and IL-6 were determined.Results: FTS group was associated with a significantly shorter postoperative hospital stay compared with conventional care group(P<0.05).Serum concentration of CRP and IL-6 in FTS group were lower(P<0.05) than in the conventional care group on postoperative day(POD) 1 and POD 3(P<0.05).CD4/CD8 ratio in FTS group were higher(P<0.05) than in the conventional care group on postoperative day(POD)1 and POD 3(P<0.05).Conclusion: Fast track surgery for colorectal cancer patients can preserve cell-mediated immunity and control inflammatory responses when compared with conventional postoperative care.
