Objective This study aimed to investigate the expression of SOX7,β-catenin and cyclin D1 in invasive breast cancer and hyperplastic disease of the breast,and explore their relationship with clinical pathology charactersis in invasive breast cancer in order to provide valuable biomarkers for the treatment and prognosis.Methods The expression of SOX7,β-catenin and cyclin D1 was neasured in 50 invasive breast cancer tissues and 30 hyperplastic disease of the breast by immunohistochemical SP method.The correlations of SOX7,β-catenin and cyclin D1 in invasive breast cancer to clinicopathologic features were analyzed,such as age,size of tumor,axillary lymph node metastasis,histological grade,pTNM stage,ER,PR,Her-2 expression and the risk.Results Immunohistochemical results showed that the positive rates of SOX7 and cyclin D1 in invasive breast cancer were 42％ (21/50)and 70％ (35/50),and the abnormal expression rates of β-catenin in invasive breast cancer was 70％ (35/50).The positive rates of SOX7 in invasive breast cancer was significantly lower than that in hyperplastic disease of the breast 70％ (21/30).The expression of SOX7 had difference between two groups (P =0.021 ＜0.05).The abnormal expression rates of β-catenin and the positive rates of cyclin D1 in invasive breast cancer wcre significantly higher than that in hyperplastic disease of the breast 43.3％ (13/30) (P =0.033 ＜ 0.05) and 20％ (6/30) (P =0.000 ＜ 0.001).The expression of β-catenin and cyclin D1 had difference between two groups.In invasive breast cancer,SOX7 and β-catenin protein expression in 12 cases,while negative expression in 5 cases; SOX7 and cyclin D1 protein positive expression in H 1 cases,while negative expression in 5 cases; β-catenin and cyclin D1 protein positive expression iu 28 cases,while negative expression in 8 cases.Results of the analysis by Spearman showed that in invasive breast cancer the SOX7 protein expression was negatively correlated with the abnormal expression of β-catenin protein and the expression of cyclin D1 protein(r =-0.282,P =0.046 ＜ 0.05 ;r =-0.327,P =0.020 ＜ 0.05)while the abnormal expression of β-catenin protein was positively correlated with the expression of eyclin D1 protein(r =0.333,P =0.018 ＜ 0.05).In invasive breast cancer the expression of SOX7 protein was correlated with age,axillary lymph node metastasis,histological grade,pTNM stage,ER,PR,Her-2 expression and the risk(P ＜0.05),but with no correlation with size of tumor (P ＞ 0.05).However,the abnoral expression of β-catenin and the positive expression of cyclin D1 in invasive breast cancer were correlated with size of tumor,axillary lymph node metastasis and pTNM stage(P ＜ 0.05),but with no correlation with age,histological grade,ER,PR,Her-2 and the risk(P ＞0.05).Conclusions SOX7.β-catenin and cyclin D1 are frequently abnormality-regulated in invasive breast cancer tissues,and the three protein may play a regulatory role through the same pathway in the development and progression of invasive breast cancer.SOX7,β-catenin and cyclin D1,s abnormal expression in invasive breast cancer correlate with the clinical pathology charactersis,and the three protein may be valuable marker for assessing the prognosis for invasive breast cancer.

Study found that in some human tumors such as breast cancer,SOX7 gene is highly likely to be a tumor suppressor gene.The tumor suppressor role of SOX7 may be accomplished by regulating the Wnt/β-catenin signaling pathway mediated the transcription process,and the abnormal Wnt/β-catenin signaling pathway is likely to play its role through the regulation of its downstream target gene Cyclin D1,etc,so that the ahnormal cell proliferation activity is unable to carry on,and thus plays the function of tumor suppressor.This review will summarize the research progress of the role of SOX7 geue and its closely related β-catenin,Cyclin D1 gene in breast cancer.

ABSTRACT:Objective To explore the expression of chemokine receptor CX3CR1 in severe acute pancreatitis (SAP)rats model and to estimate whether it can be a potential predictor of SAP.Methods Forty Sprague-Dawley rats were randomly divided into sham-operation (SO)group (n =20)and SAP group (n =20).Rats were killed at 6 h,12 h,24 h and 48 h after model induction.The serum level of CX3CR1 was measured by enzyme-linked immunosorbent assay (ELISA).The expression of CX3CR1 protein in the pancreas,lung and kidney were detected by immunohistochemistry.Results The serum level of CX3CR1 in SAP rats increased gradually after model induction and reached the peak at 24 h (542.4 pg/mL),which were significantly higher than those in SO group (P <0.05).The expression of CX3CR1 was found in the pancreas,lung and kidney tissues of SAP rats and higher than that in SO group.Meanwhile,the expression of CX3CR1 reached the peak at 24 h in the pancreas and lung and at 48 h in the kidney.Conclusion This study suggests that the chemokine receptor CX3CR1 may be one effective index for predicting the severity of acute pancreatitis and deserves further research.

Objective To observe the effect of different intra-abdominal pressure and different time points on hemodynamics,ent-tidal CO_2(P_(ET)CO_2) and airway pressure(Paw) during the procedure of gynecological laparoscopic operations.Methods 60 cases undergoing gynecological laparoscopic operations were randomly divided into two groups:the intra-abdominal pressure was 1.3kPa in groupⅠ(30 cases) and 1.9kPa in groupⅡ(30 cases).ASAⅠgrade.In both groups,systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial pressure(MAP), heart rates(HR).S-T.Paw and P_(ET)CO_2 were monitored and recorded before anesthesia(T_0),shortly after intubation (T_1),pre-pneumoperitoneum (T_2),5min after pneumoperitoneum (supine position) (T_3) and 5min (T_4),10min (T_5),20min(T_6),30min (T_7) after trendelenbury position (head down 200) and 5rain after deflation (T_8).Results In both groups SBP,DBP,MAP at time point T_3,T_4,T_5 were increased significantly compared with those of T_0 (P0.05),but there was significant difference in Paw and P_(ET)CO_2 in different time points within the same group and between the same time point in different groups after pneumoperitoneum(P

Objective To evaluate the the effect of microalbuminuria of combined treatment with fosinopril and losartan,or fosinopril,losartan monotherapy in patients with hypertension.Methods In this double-blind, intention to treat study,136 patients with hypertension were randomly assigned to receive fosinopril 10 mg/d(n= 50),losartan 50 mg/d(n=41),or a combination of fosinopril 5 mg and losartan 25 mg (n=45) qd for 4 weeks, followed by titrating to the maximum recommended doses for another 4 weeks.The primary endpoint was the difference of mean sitting blood pressure and microalbuminuria excretion at baseline and week 8.Results At week 8,the combination of fosinopril and losartan therapy lowered mean mieroalbuminuria from baseline by 26.1?10~(-8) mol/L,significantly more than either monotherapy approaches (fosinopril 20 mg,18.3?10~(-8)mol/L,P

Objective:To analyze status quo and trends of VIP services in the tertiary public hospitals of Shang-hai and provide references for health administrative departments. Methods:Health policies of VIP services in tertiary public hospitals were searched and analyzed, and the number of medical institutions, services, prices and service fees were analyzed from 2011 to 2013 . Results:There is a clear demand for VIP services in the tertiary public hospi-tals of Shanghai, and fees for rooms, nursing, and examinations for outpatient and inpatient care are decided by the hospitals. 89. 7% of the tertiary public hospitals in Shanghai offered VIP services, and the trend was steadily grow-ing. The four services that could be decided by hospitals varied greatly, and the service fees for inpatient care in-creased significantly. The total cost of VIP services in the tertiary public hospitals of Shanghai accounted 6. 2% of all costs, and the percentage of income from drugs was lower. Conclusions:VIP services in public hospitals have a his-torical necessity;management should be strengthened in the short term;public hospitals should strengthen their own management and provide VIP services regularly, and health administration departments should strengthen regulation. In the long run, it is suggested that public hospitals should draw lessons from international experiences to form a pat-tern of multi-level medical services and actively carry out cooperation with private medical institutions.

Objective:To study status quo of premium private health services and analyze the trend of its devel-opment. Method:The scope of premium private medical institutions was first defined. Then, seven indicators were used to analyze the allocation of resources;two indicators were used to analyze services;eight indicators were used to analyze costs. The entire situation of different styles of institutions through 2011 to 2013 was compared. Results:The results indicated that in the allocation of resources, the current level of premium private medical institutions is not high enough;large-scale construction is still at its early stages;and the medical personnel structure is not reasonable enough;as for service quantity, the total growth rate of premium private medical institutions is high but the service quantity is still far below that of the VIP services in public hospitals;as for medical expenses, premium private medi-cal institutions are charging high service fees, and the internal structure of the expenses is reasonable. Conclusions:Although the development of premium private health services is at an early stage, development prospects are promis-ing. Premium private health services should strengthen the aspects of medical technology, service levels, management capabilities, human resource building, and brand development.

OBJECTIVETo investigate the mechanism of norcantharidin (NCTD)-induced SMMC-7721 hepatoma cell apoptosis.

METHODSSMMC-7721 cell growth inhibition was measured by the MTT method. Apoptosis was detected by Annexin V/propidium iodide staining. The mitochondrial membrane potential was measured by flow cytometry. Western blot analysis was used to evaluate the level of cytochrome c, caspase-3, AIF, Bcl-2 and Bax expression.

RESULTSNCTD inhibited SMMC-7721 cell growth in a time- and dose-dependent manner. The cells treated with NCTD showed the loss of mitochondrial membrane potential. The activities of caspase-3, cytochrome c, AIF, and Bax were up-regulated after NCTD treatment at different doses. The expression of Bcl-2 was decreased after treatment with NCTD.

CONCLUSIONSNCTD could induce SMMC-7721 cell apoptosis. The activation of the mitochondrial pathway was involved in the process of NCTD-induced SMMC-7721 cell apoptosis.

OBJECTIVETo assess the long- term efficacy of surgical treatment of hepatic metastases from gastric adenocarcinoma.

METHODSClinical data of 938 cases with primary gastric cancer from January 1993 to October 2001 were analyzed retrospectively. Thirty- two cases received resection of hepatic metastases from gastric adenocarcinoma.

RESULTSMetachronous hepatic metastasis occurred in 24 cases(2.6% ),and 14 cases(58.3% ) underwent resection of hepatic metastases, while synchronous hepatic metastasis occurred in 90 cases(9.6% ) and 18 cases(20% ) underwent resection of hepatic metastases. The 1- 3- 5- year survival rates of hepatic resection for metachronous hepatic metastases were 73% 37% 25% respectively; while for synchronous hepatic metastases 68% 24% and 17% respectively. There were no significant differences between the two groups (P> 0.05).

CONCLUSIONSynchronous and metachronous hepatic metastases from gastric cancer should be treated by surgical resection to confirm a better prognosis.
