Triple negative breast cancer (TNBC) has its own exclusive pathological and molecular biological characteristic.At present,the treatment guidelines for triple negative breast cancer is not perfect,and the chemotherapy is the main method.A deeper insight into the targeted therapy of TNBC can improve the curative effect.

Objective To investigate the relationship of pancreatic exocrine function with the pancreatic cancer staging and the size of tumor. Methods N-benzoyl-tryrosyl para-aminobenzoic acid (NBT- PABA) test was used to measure the pancreatic exocrine function of 39 pancreatic cancer patients, 46 chronic pancreatitis patients and 20 normal subjects. In pancreatic cancer group, the relationship of pancreatic exocrine function with the size of tumor (TS) and JPS classification (T factor) was analysed. Results The rate of NBT-PABA excretion in normal subjects, chronic pancreatitis patients were (78.9±15.9)%, (58.6± 19.3)%, respectively; in mild, moderate, severe chronic pancreatitis patients, the values of NBT-PABA were (75.5±23.6)%, (57.9±21.5)%, (45.5±16.7)% ; respectively. The rate of NBT-PABA excretion in pancreatic cancer patients was (47.6±18.3)%, and the rate of NBT-PABA excretion in patients with T3+T4 stage was (42.2±21.70%, and was obviously less than (64.8±11.2)% of T1+T2 stage (P<0.05). Tthe rate of NBT-PABA excretion in patients with TS3+TS4 was (34.8±17.2)%, and was significantly lower than (55.6±23.5)% of TS1+TS2(P<0.05). The rate of NBT-PABA excretion in patients with pancreatic head cancer was (42.5±16.4)%, which was significantly lower than (71.8±9.6)% of the pancreatic body and tail (P<0.05). In the 33 patients with pancreatic head cancer, the rate of NBT-PABA excretion in patients with main pancreatic duct stricture was (54.2±14.1) %, which was significantly higher than (37.6± 14.1)% of patients with main pancreatic duct interruption (P<0.05). There was no significant difference in pancreatic exocrine function between pancreatic cancer and moderate or severe chronic pancreatitis.Conclusions The pancreatic exocrine function was related to the pancreatic cancer staging and the size of tumor to some degree,but it was affected by mass location,and it was also affected by degrees of the pancreatic duct obstruction. The pancreatic exocrine function can not be used to differentiate pancreatic cancer from moderate or severe chronic pancreatitis.

Objective To evaluate the safety of combination therapy with amlodipine and terazosin in middle aged and old male patients with essential hypertension.Methods Randomized,prospective,parallel study was carried out in middle aged and old male patients with essential hypertension in Anqing between August 2005 and February 2006.In this article,508 patients were chosen to appraise safety of the combination therapy.Results ①After 4 weeks,the heart rate of combination group changed from 68.9?7.7 to 67.7?6.9.There was no significant difference before and after treatment.②The combination group didn't affect the levels of blood glucose,lipid,electrolyte and the function of kidney and liver.③As regards tolerability,adverse experiences were observed in 4.1%,12.3%,and 13.2% of patients,respectively.Orthostatic hypertension did not happen in three groups during treatment.Conclusions The combination of amlodipine and Terazosin have no influence on the levels of blood glucose,lipid and the function of kidney and liver.Moreover,the combination was tolerated as well as its components.Through the adjustment of drug dosage,orthostatic hypotension did not happen in three groups during treatment.

Objective Measuring job satisfaction level of community health workers,providing on the evidences for the design of the relevant policy and the evaluation of job effect.Methods 57 Community Health Service centers and 54 stations were randomly selected in 12 cities in Anhui province,and all staff on the job were investigated.The questionnaires were delivered to the working staff and anonymously filled in by them.Results The total job satisfaction average score of the staff is 110.84± 18.18.The average score of pay(10.05±2.99),welfare(10.35±3.17)and promotion(10.85±3.00)are rather low.The average score of coworkers(14.78±2.11),nature of work(14.60±2.69)and supervision (13.90±3.00)are quite high.Logistic regression analysis shows the staff's duration and title are the main factors affecting their overall job satisfaction.Conclusion The overall job satisfaction level of community health workers is not high.Establishing the reasonable system of pay,welfare mechanism and the predictable promotion space are feasible choices to promote job satisfaction of community health workers

Transcatheter arterial chemoembolization (TACE) has been widely applied in palliative treatment of unresectable primary and metastatic liver cancer,and its efficiency and safety also have been widely acknowledged.However,there is a wide range of related complications,such as upper gastrointestinal hemorrhage,liver failure,pulmonary embolism,embolic cholecystitis and so on.As a serious complication of TACE,bile duct injury has been reported intermittently since the introduction of hepatic arterial embolization therapy.However,the exact pathogenesis,predisposing factors and clinical implications of the injuries remain to be clarified.As we find,by far there is no literature review about the bile duct injury after TACE for liver malignant tumors both at home and abroad.Thus the purpose of our study was to discuss such current issue of bile duct injury,and 26 articles have been included and analyzed.

ObjectiveTo investigate the correlation between ineffective esophageal motility (IEM)and gastroesophageal reflux disease (GERD).MethodsA total of 90 GERD patients were enrolled in our study,including 62 patients with reflux esophagitis (RE) and 28 with non-erosive reflux disease (NERD).All the patients underwent gastroscopy,24-hour esophageal pH monitoring and esophageal manometry.ResultsIn the RE group 30 (48.4％) patients were diagnosed as having IEM,which was significantly higher than the NERD group (6 patients,21.4％ ) (P＜0.05).Positive esophageal acid exposure was more often seen in patients with IEM than in those with normal esophageal motility (91.7％ v.s.57.2％,P ＜0.01 ).The values of total percentage of time with pH ＜4,percentage of reflux time in supine position,long-duration episodes ( ＞5 min) and the longest reflux time and DeMeester score were significantly higher in the IEM cases than those in the normal esophageal motility cases ( P ＜ 0.01 ),so was the values of number of reflux episodes (P ＜ 0.05).ConclusionIEM is the most common esophageal dysmotility in patients with GERD and closely related to distal esophageal acid exposure and RE.

Objective To evaluate the short-term efficacy and safety of combination therapy with amlodipine and terazosin in middle aged and old male patients with essential hypertension.Methods Randomized,prospective,parallel study was carried out in middle aged and old male patients with essential hypertension in Anqing community between August 2005 and February 2006.Antihypertensive efficacy and safety of the combination therapy were evaluated in 508 patient who completed the study.Results After 4 weeks treatment,the average reduction of SBP were 4.0?15.0,17.5?15.8 and 20.0?15.9 mm Hg in Terazosin group,amlodipine group and combination group,respectively(P

AIM To study the relationship between the response of hypertension patients to Adalat and the C825T polymorphism of the GNB3 gene. METHODS 554 hypertension subjects were treated with Adalat. Epidemiological and clinical data were collected. Genotypes of the GNB3 gene were measured by the PCR RFLP method. Linear and logistic regression were used to analyze the association between GNB3 genotypes and the response to Adalat. RESULTS The frequency of the 825T allele in our hypertensive group (48 4%) was slightly higher than that of the normal Chinese reported previously by Siffert W et al. (42%). The average SBP decrease after 15 days of Adalat treatment of subjects with the T allele was significantly less than that of the subjects with the CC genotype (?=-3 3, P= 0 03). Using logistic regression, the subjects with the T allele were less likely to reach good treatment result compared to those with the CC genotype (OR=0 33, P =0 02). CONCLUSION The GNB3 gene C825T polymorphism is related to the response to Adalat.
