Objective Based on the 2012 Atlanta classification criteria, to study the value of C-reactive protein (CRP) and procalcitonin (PCT) in the early forecasting acute pancreatitis (AP). Methods Eighty-three patients with AP were selected. The patients were divided into mild AP (MAP) group (39 cases), moderately severe AP (MSAP) group (31 cases) and severe AP (SAP) group (13 cases) according to the 2012 Atlanta classification criteria. Twenty-seven healthy people were selected as control group. The levels of serum CRP and PCT were measured. The predictive value of serum CRP and PCT levels for SAP, infectious pancreatic necrosis (IPN), organ failure and death risk was assessed using the area under the curve (AUC). Results The serum CRP and PCT levels in MAP group, MSAP group and SAP group were significantly higher than those in control group: (49.84 ± 12.26), (89.77 ± 22.10) and (123.69 ± 37.09) mg/L vs. (3.92 ± 1.37) mg/L, (1.15 ± 0.42), (2.44 ± 0.61) and (3.27 ± 0.96)μg/L vs. (0.41 ± 0.13)μg/L, and those in MSAP group and SAP group were significantly higher than those in MAP group, those in SAP group were significantly higher than those in MSAP group, and there were statistical differences (P<0.05). The Spearman correlation analysis result showed that AP severity was positively correlated with serum CRP and PCT levels (r = 0.652 and 0.714, P<0.05). The accuracy of serum CRP level for forecasting SAP and IPN was medium (AUC = 0.73 and 0.76), and for forecasting organ failure accuracy was low (AUC = 0.67). Serum CRP showed no significance in forecasting death risk (AUC = 0.46). The accuracy of serum PCT level for forecasting SAP, IPN and death risk accuracy was medium (AUC = 0.71, 0.86 and 0.80), and for forecasting organ failure accuracy was low (AUC =0.64). Conclusions Based on the 2012 Atlanta classification criteria, the accuracy of serum CRP level for forecasting SAP is higher than that of serum PCT level, the accuracy of serum PCT level for forecasting IPN and death risk is higher than that of serum CRP level, and accuracy of serum CRP and PCT levels for forecasting organ failure are low.

Streptococcus pneumoniae is one of the most common cause of invasive disease,such as bacteremia,meningitis,and empyema,et al.But there has significant difference on the incidence of invasive pneumococcal disease among different regions and differernt groups of people.In addition the severity and mortality of invasive pneumococcal disease are closely related to the changes of serotypes,virulence of streptococcus pneumoniae and also the human immune response.The pneumococcal vaccination is an important measure to prevent streptococcus pneumoniae infection,providing good protection to vaccinees and createing herd immunity effect.This article briefly describes the pathogenesis,risk factors and preventive strategies of invasive pneumococcal disease.

The effects of positive end-expiratory pressure (PEEP) on pulmonary shunt were studied during gen- eral anesthesia and postoperative period.Twenty cholecystectomy patients were randomly divided into experiment group (group P) and control group (group Z). PEEP and ZEEP were used separately after induction. Artery blood and mixed blood from the right ventricle were taken for blood gas analysis and determine the amount of pulmonary shunting before anesthesia. half and hour, one and half an hour and two and half an hour after anesthesia and one hour after the operation.The results showed that shunt in group P decreased gradually during general anesthesia and returned to the level of preoperation at an hour after operation. Shunt in group Z was increased continually and the level was significantly higher than preoperation an hour after operation. Shunt between two groups was significant difference (P

Purpose:To investigate method of early detection of breast cancer with microcalcification observed by mammograph but without palpable mass clinlcally.Methods:Stereotatic core needle biopsy (SCNB) were performed in 35 patients with calcification observed by mammography,and 29 people received stereotatic needle localized breast biopsies (NLBB).All tissues were routinely processed.Microscopic analysis of calcification and morphologic analysis of calcifica- tion were done,as well as histologic diagnosis.Results:Among the 35 specimens of SCNB,microscopic calcification,in- traductal carcinoma and invasive ductal carcinoma were detected in 24,8,and 4 respectively.Calcification was identified in 25 of the 29 cases of NLBB.Five cases of intraductal carcinoma,six cases of invasive ductal carcinoma as well as one case of invasive lobular carcinoma were diagnosed in these 29 patients.Conclusions:With close cooperation among pathol- ogists,surgeons and radiologists,the application of SCNB and NLBB may benefit the early detection of breast cancer with microcalcification observed by mammograph but without mass being palpable clinically and finaly improve the survival of breast cancer patients.

Objective To explore the pattern of lymph node metastasis in patitsen with squamous cell carcinoma of the thoracic esophagus and its significance in lymphadenectomy.Methods The clinical data of 230 patients who received radical esophagectomy with three-field lymphadenectomy was analyzed.The metastatic sites of lymph nodes were correlated with tumor location by chi-square test.Logistic regression was used to analyze the relationship between clinic pathoingical factors and lymph node metastasis.Results Lymph node metastases were found in 133 of the 230 patients(57.8%).The average number of resected lymph nodes was 25.3? 11.4 per patient(range 11～71).The rates of lymph node metastasis were 41.6%,19.44%and 8.3%in the neck,thoracic medi- astinum and abdominal cavity for patients with upper thoracic esophageal carcinoma,33.3%,34.7%and 14%for patients with mid- die thoracic esophageal carcinoma and 36.4 %,34.1%and 43.2 %for patients with lower thoracic esophageal carcinoma.No signifi- cant difference in cervical or thoracic metastatic rate was observed among upper,middle and lower thoracic carcinoma.The difference in lymph node metastatic rate for nodes in the abdominal cavity was significant among upper,middle and lower thoracic carcinoma. The lower thoracic esophageal cancers were more likely to metastasize to the abdominal cavity.Logistic-regression showed depth of tu- mor invasion and angiolymphatic invasion were factors influencing lymph node metastasis.Conclusion Cervical and mediastinal node dissection should be performed independently from tumor location.Abdominal node dissection should be conducted more vigorously for lower thoracic esophageal cancer than of other locations.Patients with greater tumor grade,depth of tumor invasion and angiolymphatic invasion were more prone to develop lymph node metastasis.
