Chemotherapy and endocrine therapy are two kinds of important treatment modalities of breast cancer with hormone receptor-positive. Adjuvant chemotherapy whether can be proposed to the individual patient or not according to tumor burden factors, multi-gene prognostic signatures detection and molecular subtype classification for breast cancer. There are four different endocrine strategies, and each of them has its own advantage over others and cannot be replaced by others. Individualized therapy should be performed to Luminal A and Luminal B breast cancers.

Objective To analyse the cause of misdiagnosis of tuberculosis peritonitis and discuss feasibility for diagnosis of tuberculosis peritonitis by laparoscopy. Methods 12 patients misdiagnosed as tuberculosis peritonitis were retrospectively analysed. Results Tuberculosis peritonitis wrongly diagnosed because of atypical clinical behaviors in spite of specific laboratory examination. However, laparoscopy could diagnose tuberculosis peritonitis exactly and quickly. Conclusion Laparoscopy is an effective method of diagnosis for tuberculosis peritonitis.

Objective To compare the result of percutaneous or open drainage for muhilocular bacterial liver abscess. Methods The clinical data of 45 patients with multilocular bacterial liver abscess were reviewed retrospectively over the past 5 years. Twenty-one cases underwent B-us or CT-guided pereutaneons drainage (PD) and 24 received surgical drainage (SD) as the first-line treatment. The treatment outcomes in both groups were compared, and clinical end-points included time to defervescence, failure of treatment, secondary procedures, hospital stay, morbidity, and mortality. Results The time of defervesecnce was not statistically different between the two groups (4.85 day vs. 4.38 days, P＞0.05). However, patients in SD group suffered from less treatment failures (2 cases vs. 9 cases, P<0.05), less requirement for secondary procedures (1 cases vs. 11 cases,P<0.01), and shorter hospital stay (8 day vs. 11 days, P<0.05). There was no difference in morbidity or mortality rates between the two groups. Conclusions It was concluded that for multilocular liver abscess, SD provides better clinical outcomes than PD in terms of treatment success, number of secondary procedures, and hospital stay with comparable morbidity and mortality rates. SD should be considered as first-line treatment for multilocular bacterial liver abscesses.

Objective To explore the suitable range of PT-INR for Chinese people with acute deep venous thrombosis (DVT) treated by warfarin anticoagulation therapy. Methods Eighty seven DVT patients with indications to warfarin anticoagulation therapy were enrolled into the study and divide into two groups randomly. Patients from group A (n=47) took warfarin to adjust the PT-INR to range 1.7-2. 5,and patients from group B (n =40) took warfarin to adjust the PT-INR to range 2. 0-3. 0. The therapeutic effectiveness and the incidence of bleeding complications were compared between two groups. Results Forty-six patients (46/47,98%) had limb swelling symptoms relief in group A with one exception,which was diagnosed as pelvic tumor by ultrasonography,CT and tumor markers examination later. No patient underwent bleeding in group A Thirty eight patients (38/40,93%) had limb swelling symptoms relief in group group B with two exceptions,of which one case had Cockett syndrome and the other one had unknown aetiology. The total effective rate of group B was 95% . As to the complications of this group,3 patients had slight gum and nasal mucous membrane bleeding, 1 patient developed gastrointestinal bleeding. No patients had pulmonary embolism in both groups. Conclusion For Chinese people,anticoagulation therapy of acute deep venous thrombosis to adjust the range of PT-INR to 1.7-2. 5, shows good effectiveness and significantly reduced bleeding complications.

In order to analyze the genotype of RhD-negative blood donors with immune antibodies in Harbin, the voluntary blood donors from 1 April 2008 to 30 september 2011 were detected serologically to determine the RhD-negative donors. The blood donors confirmed to be RhD negative were detected to screen the immune antibodies, the samples with immune antibodies were analyzed by PCR-SSP and DNA sequencing to detect RhD genotype. The results showed that the 12 cases of the immune antibodies (0.95%) were screened out from 1265 cases of RhD-negative donors, among which 9 cases showed anti-D-antibody, 3 cases showed anti-(D+C) antibody; 10 cases were RhD-negative, 2 cases were RHD 711D(el)C. It is concluded that RhD negative and RHD 711D(el)C are easy to be immunized to produce the immune antibodies; RhD-negative population, especially women should be highly aware of avoiding mis-transfusion of RhD-positive blood, and also avoiding multiple pregnancies resulting in newborn's hemolytic disease.

The aim of this study was to investigate the effects of β-catenin on the tumorigenicity of K562 cells in vivo. The β-catenin expression in K562 cells was down-regulated through sequence-specific siRNA, and the treated K562 cells were implanted into BALB/c nude mouse subcutaneously. And the tumor-forming rate and tumor-forming curve (interference group) were observed. Experiments were divided into 3 group: interference group (implanted K562 cells transfected with β-catenin interfering plasmid DNA), control group (implanted K562 cells transfected with unrelated sequence plasmid DNA) and untreated group (implanted K562 cells transfected without plasmid DNA). The results indicated that the tumor-forming rates of untreated group (n = 9), control group (n = 8) and interference group (n = 9) were 100%, 87.5% and 0% respectively. The tumor-forming rate of interference group was significantly lower than those of the other 2 groups (p < 0.001). Comparison of the tumor-forming curve between 3 groups, showed that in first 2 groups existed tumor-forming and their final tumor volumes were almost the same, but the tumor growth of untreated group was faster than that in control group; while in the interference group there was not tumor-forming. It is concluded that the β-catenin expression level in K562 cells is down-regulated through the interference of sequence-specific siRNA, thus affecting their tumor-forming potential in vivo.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD), functional dyspepsia (FD), and peptic ulcer disease (PUD) impact the daily lives of affected individuals. The aim of this study was to compare the risk factors and impacts on life quality of overlapping FD or PUD in patients with GERD. METHODS: Data from patients diagnosed with GERD were collected between January and November 2009. FD was defined using the Rome III diagnostic criteria. The overlapping GERD-FD or GERD-PUD groups were classified as concomitant GERD and FD or peptic ulcers. The characteristics of these individuals were analyzed. RESULTS: There were 63, 48, and 60 patients in the GERD only, overlapping GERD-FD, and overlapping GERD-PUD groups, respectively. Significantly younger age, female gender, lower body weight and body mass index, and higher rates of tea consumption were noted in the GERD-FD group. Patients in the GERD-FD group exhibited the lowest quality of life scores, both with respect to physical and mental health, on the Short Form 36 domains. CONCLUSIONS: Patients with concomitant GERD and FD were more likely to be younger and female. Overlapping GERD and FD had the worst impact on the quality of life of the affected individuals.

BACKGROUND/AIMS: The aim of this study was to investigate the associations between obesity and erosive esophagitis (EE) or Barrett's esophagus (BE) in a Chinese population. METHODS: Data from subjects were retrospectively collected from 2006 to 2009. Individuals with BE were identified and age- and sex-matched at a 1:2 ratio with normal esophagocardial junction and EE patients. The subjects were stratified into two groups: the normal weight group and overweight/obesity group (body mass index ≥25 mg/m²) or the normal waist group and abdominal obesity group (waist circumference ≥90 cm for men and ≥80 cm for women). RESULTS: Overall, 45%, 72%, and 52% were overweight/obese and 23%, 65%, and 18% had abdominal obesity in the normal, EE, and BE groups, respectively. Positive associations were identified between EE and overweight/obesity (odds ratio [OR], 3.14; 95% confidence interval [CI], 1.75 to 5.66) and abdominal obesity (OR, 6.22; 95% CI, 3.34 to 11.57); however, the associations were nonsignificant between BE and overweight/obesity (OR, 1.32; 95% CI, 0.67 to 2.61) or abdominal obesity (OR, 0.73; 95% CI, 0.31 to 1.73). Female BE patients had a significantly increased rate of being overweight/obese. CONCLUSIONS: Obesity is a contributing factor in EE. The association of BE and obesity was not significant, with the exception of female BE cases.
