Objective To investigate the expression of breast cancer specific gene 1( BCSG1) in breast cancer tissues and its clinical significance.Methods The expression of BCSG1in 51cases of breast cancer tissues and 35 cases of adjacent tissues was determined by fluorescence quantitative polymerase chain reaction (FQ-PCR) and immunohistochenistry.Results FQ-PCR showed the expression level of BCSG1mRNA in breast cancer and adjacent tissues was 1.072 ± 0.178 and 0.324± 0.135 respectively.Immunohistochemistry showed the expression rate of BCSG1protein in breast cancer and adjacent tissues was 74.5% (38/51) and 14.3% (5/35).The expression of BCSG1mRNA and protein was dramatically increased in breast cancer tissues compared with that in normal background breast tissues (P < 0.05).BCSG1mRNA and protein expression was significantly different in patients with lymph node metastasis and higher Nottingham prognostic index (P < 0.05 ),and there was no significant difference with the pathological type of breast cancer,or status of ER,PR,and c-erbB2 ( P > 0.05 ).Conclusions BCSG1is highly expressed in breast cancer tissues,which is closely related to the development and clinical prognosis of breast cancer.BCSG1is very likely to play an important role in the pathogenesis of breast cancer.

ObjectiveTo evaluate nipple-areola complex sparing modified radical mastectomy for breast cancer.MethodsClinical data of 159 breast cancer cases undergoing NAC sparing modified radical mastectomy from Jan 1998 to Dec 2009 were retrospectively analyzed.ResultsNAC sparing modified radical mastectomy was successfully carried out in 141 out of the 159 cases ( 88.68% ).In 14 cases (8. 81% ) the original operative protocol was changed to modified radical mastectomy or radical mastectomy during the operations because NAC ischemia in 4 (2. 52% )cases, NAC occult involvement or dysplasia in 5 cases (3. 14% ), Ⅲ level lymph node metastasis was found in 3 cases (1.89%). Postoperative complete nipple necrosis occurred in 4 (2. 52% ) cases. Other significant postoperative complications included nipple necrosis in 20 cases ( 12. 58% ), skin flap necrosis and infection in 11 cases ( 6.92% ), subcutaneous hydrops in 10 cases (6. 29% ). All patients got follow-up ranging from 15 to 96 months,median follow-up was 51 months. Local region recurrences were observed in 5 cases (3. 14% ), distant metastasis in 2 cases ( 1.26% ). There was no recurrence in the region of NAC.ConclusionsNipple-areola complex sparing modified radical mastectomy is oncologically safe by strict preoperative selection criteria and strict operative procedure.

ObjectiveTo investigate the clinicopathological characteristics of nipple-areolar complex (NAC) involvement in patients with operable breast carcinoma and to determine the indications and risk factors of NAC-sparing modified radical mastectomy. Methods407 female patients with primary breast cancer were included in the study.Data like tumor position, tumor size, the distance from the tumor to the margin of areolar (D) were recorded.NAC sample in vitro was collected and routine pathological examination was performed.Statistical methods were employed to analyze the relation between the clinicopathological factors and NAC involvement.ResultsThe rate of NAC involvement was 13.27% (54/407).NAC involvement had no statistically significant correlation with age or histological type, but had statistical correlation with tumor position, D value, tumor size, TNM stage, clinical manifestation of NAC, and status of axillary lymph nodes(P < 0.05).ConclusionsTumor position, D value, tumor size, TNM stage, clinical manifestation of NAC and status of axillary lymph nodes are the major influential factors for NAC involvement.The indications of NAC-sparing modified mastectomy:1.in Ⅰ or Ⅱa TNM stage; 2.patients have strong will to preserve NAC or breast appearance; 3.noncentric tumor (D≥2 cm) ; 4.the maximum diameter of tumor should be less than 3 cm; 5.no abnormal manifestation like nipple discharge, eczematoid change or nipple inversion happened.6.no occult involvement in subareolar tissues was found by frozen pathology.

Objective To investigate the relationships between the level of heat shock protein (HSPs) 70 and severity of sepsis in order to find its effects on the status of sepsis and the prognosis of the patients. Methods In total, 120 patients diagnosed to be suffering from sepsis from the emergency department were selected as studying subjects. According to SAPS Ⅱ score, all of these patients were divided into mild, moderate and severe groups (n =40 in each group) , and at the same time, 40 healthy volunteers were studied as controls. The levels of intracellular HSPs70 in peripheral blood neutrophil cells in the mild, moderate and severe groups were determined by using flow cytometry, while serum levels of procalcitonin (PCT) and C-reactive protein ( CRP) were measured as well. Results ① The levels of heat shock proteins HSPs70 in neutrophil cells and PCT in patients with sepsis escalated gradually with the increase in SAPS Ⅱ score, and there were significant different among the mild, moderate, and severe sepsis groups(P<0.05). ② In all septic patients, the death happened only in the severe group. Compared other markers in the survivals , the level of heat shock protein HSPs70 was significantly higher in fatal patients. ③ In curve plot analysis in the patients with sepsis done by the curve of receiver operating characteristic (ROC) , the area of HSPs70 in neutrophil cells under the curve was significantly larger as compared with that of PCT and CRP. Conclusions Heat shock protein HSPs70 has a certain clinical value in determining the severity of disease and prognosis of patients suffering from sepsis.

BACKGROUND:Transforming growth factor β1 (TGF-β1) and interleukin 1β (IL-1β) have been reported to play an important role in the occurrence and development of primary osteoarthritis. OBJECTIVE:To investigate the association between gene polymorphisms of TGF-β1 and IL-1β and primary knee osteoarthritis. METHODS: Han and Uyghur elderly populations in Xinjiang Uygur Autonomous Region, China were surveyed on the prevalence of osteoarthritis, followed by allotted to osteoarthritis and health groups according the symptoms and radiography. Genotyping TGF-β1-509C/T and -1348C/T and IL-1β-511C/T was performed to analyze the relationship between the gene polymorphisms of TGF-β1 and IL-1β and osteoarthritis. RESULTS AND CONCLUSION:Alleles T and C with genotypes CC, CT and TT were detected in both two groups. In the Uygur population, the genotype frequency of TGF-β1-509C/T and IL-1β-511C/T showed significant difference between osteoarthritis and health groups (P < 0.05). In the Han population, the genotype frequency of TGF-β1-1348C/T showed significant difference between two groups (P < 0.05). These results suggest that the Uygur individuals carrying TT genotype of TGF-β1-509C/T and IL-1β-511C/T, and Han people carrying the TT genotype of TGF-β -1348T are more susceptible to osteoarthritis.

Objective To explore the rule of central region lymph nodes metastasis in differentiated thyroid carcinoma (DTC) and the significance of central region lymph nodes neck dissection in surgical operation for DTC.Methods The clinical and pathological data of 122 lymph nodes in 109 patients (31 female and 78 male) with DTC undergoing neck lymph nodes ( central region lymph nodes included) dissection from Jan.2003 to Jun.2007 in our hospital were analyzed retrospectively.According to preoperative physical examination and imaging analysis,patients were divided into clinical cervical lymph nodes metastasis ( cN + ) group and clinical no cervical lymph nodes metastasis (cNO) group and compared respectively with their pathological data after surgery.Resuits Of the 122 lymph nodes,lymph node metastasis rate was significantly higher in region Ⅵ than in region Ⅱ,Ⅲ and Ⅳ.The difference had statistical significance (P <0.01 ).65.6% (80/122) metastasis was in the central region.81.2% (56/69) patients in cN + group and 45.3% (24/53) patients in cN0 group had central region lymph nodes metastasis.Conclusions Central region lymph nodes metastasis is common for patients with DTC.Routine neck dissection in central region should be done in DTC operation.
