Objective To investigate dilatancy effect of the Hypertonic Sodium Chloride Hydroxythyl Starch 40 injection (HSH) for the treatment of hemorrhagic shock.Methods 70 cases with trauma induced hemorrhagic shock were randomly divided into two groups:Hypertonic Sodium Chloride Hydroxythyl Starch 40 injection group (H group), Ringer's group (R group), 35 cases in each group.Patients of H group were infused HSH10ml/kg within 30 minutes, the R group were infused Ringer's 10ml/kg at the same time.Central venous pressure (CVP), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and oxygen saturation (SpO2) were monitored before the infusion, after the infusion and finished 30 minutes separately.Na+、Cl-、K+ were examined before infusion and after infusion respectively.Results The CVP、SBP、DBP、HR and SpO2 in both groups were improved than before infusion, but those in H group is much better than R group, with statistical significance (p<0.05).The potassium was reduced moderately and sodium ions and chloride ions were increased in H group than in R group, but it was still within normal range.Conclusion Appling HSH (10ml/kg) to patients with hemorrhagic shock can be better than the compound prescription of sodium lactate.

Objective To observe the clinical effect of artificial ventilation combined continuous positive airway pressure(CPAP) with removal of tracheobronchial foreign bodies for children and to explore the possibility and security of the method. Methods 60 children with tracheobronchial foreign body, underwent total intravenous anesthesia ,were randomly divided into A group and B group. Each group had 30 cases. A group was given artificial ventilation with CPAP. The bronchofibroscope was connected to anesthesia machine with side hole after induction for 3 minutes,and high fresh gas flow(10 ～ 15L/min) was given to maintain continuous positive airway pressure. B group were given high frequency jet ventilation(HFJV) ,60 ～ 100 bpm. The mask ventilation was given in stand of bronchofibroscope when SpO2 ＜ 90% and until SpO2 improved. MAP, HR, ECG, SpO2, PaO2, PaCO2 were monitored and recorded at time points: T0 (entered operation room), T1 (beginning of bronchofibroscopy), T2 (5 min after bronchofibroscopy), T3 (10 min after bronchofibroscopy), T4 (end of operation). The side effects, the rate of fail to bronchofibroscopy and the rate of intubations after operation in two groups were observed and recorded. Results The HR of post-anesthesia in two groups significantly decreased than those at T0 (P ＜ 0.01), but no difference showed in HR between two groups(P ＞ 0.05). SpO2 and PaO2 of post-anesthesia in two groups significantly increased than those at T0 (P ＜0. 01) ,PaO2 at T1 ,T2 ,T3 in A group were significantly higher than those in B group(P ＜0.05). PaCO2 gradually increased after bronchofibroscopy in two groups ,and the values in A group was significantly lower than in B group(P ＜0.05 or 0. 01). There were no significant differences in the rates of fail to bronchofibroscopy and of intubations after operation between two groups, but the total number of B group was higher. Conclusion Artificial ventilation with CPAP for children with removal of tracheobronchial foreign bodies was safe and practical, and has a better controllability, a minor effect to respiratory function, deserve popularizing.

ObjectiveTo evaluate the effect of preoperative percutaneous transhepatic biliary drainage (PTBD) on postoperative outcomes after pancreaticoduodenectomy.MethodsThe clinical data of 115 patients undergoing pancreatoduodenectomy between 2001 and 2009 were retrospectively analyzed.The diagnosis of periampullary cancer or cancer of the pancreatic head was confirmed histologically.The preoperative total bilirubin level was more than 100 μmol/L and there was no concomitant cholangitis.Forty-two patients underwent PTBD (PTBD group),and 73 were not drained (early operation group).The following parameters were analyzed:wound infection,intra-abdominal abscess,intra-abdominal or gastrointestinal bleeding,biliary or pancreatic leakage,gastroparesis,morbidity and mortality.The length of hospital stay and cost were also assessed.ResultsThe perioperative mortality and morbidity were 2.38％/54.76％ in the PTBD group and 2.74％/50.68％ in the early operative group,respectively.There were no significantly differences between these two groups.Similar results were obtained in biliary leak,pancreatic leak,intra-abdominal infection,wound infection and gastroparesis.The length of hospital stay and cost were significantly less in the early operation group than the PTBD group.ConclusionsPTBD had no beneficial effects on postoperative outcomes following pancreaticoduodenectomy.For distal biliary obstruction,PTBD should not be carried out routinely.

Objective To study the value of transcatheter arterial chemoembolization (TACE)in combination with portal vein chemotherapy (PVC) after resection of hepatocellular carcinoma to prolong survival. Methods From January 2000 to July 2007, 168 patients with hepatocellular carcinoma (HCC) underwent tumor resection in our hospital. After operation, TACE in combination with PVC was performed in 48 patients (combined group), TACE alone in 26 (TACE group), PVC alone in 50 (PVC group) and none of the above in 44 (control group). All the patients were followed up for 17-96 months. The 1-, 3-and 5-year survival rates were compared among the 4 groups. Results Accumulative 1-, 3-and 5-year survival rates were higher in the combined and TACE groups than in PVC and control groups. Conclusion After resection of HCC, combined use of TACE and PVC is the same as TACE in prolonging patient survival. However, it is better than PVC alone and non-surgical procedure.

According to 'National Standard of Undergraduate Teaching Quality for Nursing Science', the mode of community nursing practice was explored and implemented by the School of Nursing in Tianjin Medical University. Focus on competency, the syllabus of community nursing practice was revised. Optimizing the management system of community nursing practice, developing the team of high-quality teachers, building standardized community nursing practice bases, and improving the evaluation system of community nursing practice aimed to enhance comprehensive quality of nursing undergraduates and the quality of community nursing practice. Within the concept of "big health", our school is exploring the new mode of combining community nursing practice with health management-oriented nursing personnel training, which lays an important foundation for training applied nursing talents to meet the needs on development of community health services.

Objective To investigate the basic clinical features in 371 cases of colorectal polyps and its relationship with fecal occult blood and carcinoembryonic antigen(CEA).Methods The retrospective analysis was performed on 371 inpatients with colo-rectal polyps.The relationship among gender,number of polyps and polyps anatomical site in different ages of patients was investi-gated,and the relationship between fecal occult blood and CEA with polyp canceration was analyzed by 1.5?3.0 years follow-up. Results Among 371 cases of colorectal polyps,the female patients were gradually increased and single polyp was gradually de-creased along with the age increase;due to different ages,there was the statistically significant difference in the polyp locations (χ2 =9.759,P=0.045);the distribution difference of the patients with polyp canceration among three age groups was statistically significant(χ2 =5.138,4.107,13.153,P<0.05).The cases of fecal occult blood positive and CEA abnormal increase were gradual-ly increased with age increasing(χ2 =15.544,11.959,P<0.01);with the number of polyps increasing,the cases of fecal occult blood positive showed the increasing trend(χ2 =14.043,P=0.001);the canceration rate in colorectal polyp cases of fecal occult blood positive and CEA abnormal increase was significantly higher than that in the cases of fecal occult blood negative and CEA normal range(χ2 =40.165,43.249,all of P< 0.001).Conclusion The fecal occult blood test and CEA detection results have a certain significance to the follow up for preventing colorectal polyps canceration.

In order to study the significance of CD276 and CD133 in the development and progression of colorectal cancer (CRC),the expression of CD276 and CD133 was detected by immunohistochemistry in CRC and precancerous lesions.The results showed that the intensity of CD276 and CD133 in CRC samples was higher than that in adenoma group and non-adenoma group.CD276 and CD133 single and double positive expression were significantly correlated with CRC lymph node metastasis,distant metastasis and survival.CD276 and CD133 are significantly correlated to the development and progression of CRC and associated with poor prognosis.
