Discussion on the method of disease cost accounting by appling clinical pathway

Objective　To explore a scientific disease cost accounting. Method　Disease cost accounting = disease cost accounting of clinic pathway + disease basis cost accounting. Conclusions　It is the tendency with the medical reform for the social security department to pay by disease for the hospitals, as a result, both social security department and hospitals have to resort to the scientific way in terms of cost accounting of disease. And it is practical and effective by means of cost accounting for clinic pathway.

Value of Thyroid Stimulating Hormone Inhibition Therapy in Differentiated Thyroid Carcinoma

Objective To investigate the value of thyroid stimulating hormone (TSH) inhibition therapy in postoperative patients with differentiated thyroid carcinoma. Methods One hundred and six patients with differentiated thyroid carcinoma after total or near-total thyroidectomy were divided into two groups: TSH inhibition therapy group and thyroid hormone replacement therapy group. The non-recurrence and (or) non-metastasis rate in two groups was analyzed retrospectively by Wilcoxon statistical analysis. Results The non-recurrence and (or) non-metastasis rate of 3-， 5- and 10-year in TSH inhibition therapy group were 98.31%， 92.41% and 75.45% respectively， and were higher than those (93.57%， 84.18% and 52.06% respectively) in thyroid hormone replacement therapy group （P=0.046 5）. Conclusion TSH inhibition therapy after total or near-total thyroidectomy may be an essential treatment for differentiated thyroid carcinoma patients.

Safety Assessment of Low Molecular Heparin Instead of Anticoagulant in Patients with Inguinal Hernia during Perioperative Period

ObjectiveTo evaluate the safety and efficiency of perioperative low molecular heparin (LMH) as the replacement of anticoagulant for patients with inguinal hernia. MethodsSixty-three patients with oblique inguinal hernia from April 2009 to April 2012 in this hospital were analyzed retrospectively.Seventeen cases because of other diseases were long-term oral aspirin anticoagulant therapy (aspirin group), 11 cases because of other diseases were long-term oral warfarin anticoagulant therapy (warfarin group), anticoagulant therapy was replaced by continuing LMH 7 d before operation in the aspirin group and the warfarin group.The other 35 cases did not take any anticoagulant therapy (control group). Results①The demography and preoperative international normalized ratio were similar among three groups (P > 0.05).②All the patients were followed-up.The duration of follow-up ranged from 12 months to 18 months.There were no statistical differences of the scrotal hematoma or subcutaneous hematoma, operation time, postoperative hospital stay, and VAS scoring among these three groups (P > 0.05).There was no recurrence in all the patients. ConclusionFor a long term application of anticoagulant in patients with oblique inguinal hernia, perioperative application of LMH instead of anticoagulant does not increase the risk of bleeding, and could prevent thrombosis.

Analysis of Clinicopathological Characteristics and Prognostic Factors of 31 Patients with Combined Hepatocellular and Cholangiocarcinoma

ObjectiveTo explore the clinicopathological characteristics of combined hepatocellular and cholangiocarcinoma (cHCC-CC), and the prognostic factors associated with survival. MethodesThe clinical features of 31 patients with cHCC-CC from 1995 to 2010 in West China Hospital of Sichuan University underwent liver resection were analyzed retrospectively. The prognostic factors were analyzed by using univariate and multivariate analysis. ResultsOf these 31 patients, 25 men and 6 women, with a median age of 58 years, underwent liver resection for cHCC-CC. Twentythree cases (74.2%) showed positive of hepatitis B surface antigen (HBsAg), 13 cases (41.9%) had elevated AFP≥20μg/L, 18 cases (58.1%) with liver cirrhosis, 8 cases (25.8%) showed presence of lymph node metastases. The 1-, 3-, and 5-year overall survival rates of these patients were 61.3%, 32.3%, and 12.9%, respectively. Univariate analysis showed that invasion of portal vein, microscopic tumor thrombi, positive resection margins, and lymph node involvement were significant prognostic factors. Multiple analysis revealed the positive resection margins and lymph node involvement were independent prognostic factors for overall survival. ConclusionsThe prognosis of patients with cHCC-CC is poor. R0 resection is the only available treatment in curing these patients.

Diagnostic Value of Serum Bilirubin Level in Acute Appendicitis

目的探讨血清胆红素升高在急性阑尾炎坏疽、穿孔中的诊断价值。 方法回顾性分析2011年6月至2013年8月期间我院住院行手术治疗的急性阑尾炎患者的临床病理资料，比较多种指标诊断急性复杂阑尾炎的准确性。 结果复杂阑尾炎患者血清总胆红素（STB）水平明显高于非复杂阑尾炎患者（P＜0.001）。STB升高诊断复杂阑尾炎的敏感性及特异性分别为33.3%和86.2%，而血清直接胆红素(SDB）升高（≥6.65μmol/L）诊断复杂阑尾炎的敏感性及特异性分别为78.1%和63.5%。系统炎症反应（SIRS）评分与STB联合诊断具最佳诊断效能，受试者操作特征曲线下面积为0.741，而血清白细胞计数（特异性40.7%）诊断准确性相对较低。 结论SDB升高诊断急性阑尾炎坏疽、穿孔的准确性较佳，STB与SIRS评分联合诊断可作为早期鉴别诊断复杂阑尾炎的参考指标。

An Observation of the Protective Effects of SAdenosylLMethionine on Liver Function in Cirrhotic Rats after Hepatectomy

ObjectiveTo investigate the protective effect of SadenosylLmethionine on liver regeneration and liver function in cirrhotic rats after hepatectomy. MethodsCirrhosis was successfully induced by injection of 40% CCl4.Then,partial hepatectomy (about 30%) was performed in all rats. Cirrhotic rats were divided into 3 groups,namely,cirrhotic group (normal saline 5 ml/d,for 15 postoperative days，n=20),treatment group 1 〔S adenosylLmethionine 10 mg/(kg·d),for 15 postoperative days,n=16〕 and treatment group 2 〔SadenosylL methionine 20 mg/(kg·d),15 postoperative days,n=16〕,and normal control group was also established. Animals were sacrificed at the 15th postoperative day and 30th postoperative day to take samples for detection of liver function (Alb,ALT,TB,TBA) and serum TNFα.Liver tissues were also observed under light microscope and electron microscope. ResultsIn two treatment groups,at the time point (15 postoperative days or 30 postoperative days),concentrations of ALT,TB,TBA,Alb and TNFα were decreased significantly as compared with cirrhotic group (P ＜0.01),and concentration of Alb was increased significantly (P＜0.01).In contrast, there were no obvious difference in the same time point of different dosetreatment groups (Pgt;0.05),but the decrease of ALT,TB,TBA,TNFα and the increase of Alb were more significant at the second time point (30th postoperative day) than the first time point (15th postoperative day) when treated with same dose (P＜0.01).At the same time,concentration between TNF α and ALT,TB,TBA showed a positive correlation (P＜0.01),and the concentration between TNFα and Alb showed a negative correlation (P＜0.01).In addition, the histopathology showed SadenosylLmethionine had effects of protecting liver function and enhancing liver regeneration. ConclusionThe study suggests that SadenosylL methionine has the efficacy of enhancing liver regeneration and improving liver function.

An Investigation of the Relationship Between Peripheral T Cell Apoptosis and Specific Immune Tolerance Induced by T Cell Vaccination

ObjectiveTo investigate the relationship between peripheral T cell apoptosis and specific immune tolerance induced by T cell vaccination（TCV）. MethodsT cell vaccinations were made from the spleen cells of SD rats, which were induced by ConA and were challenged with the spleen cells of Wistar rats. Normal SD rats were vaccinated intraperitoneally with TCV (experimental group) or RPMI 1640 culture buffer (control group) respectively .Oneway mixed lymphocyte reaction (MLR) were performed,the apoptosis of peripheral T cell were assayed using flow cytometric analysis before and after vaccination.ResultsIn experimental group, the result of MLR showed that the response captivity of SD rat spleen cells were suppressed significantly after vaccination in comparison with prevaccination (Plt;0.01) and the percentage of peripheral T cell apoptosis was increased significantly after vaccination compared with prevaccination (Plt;0.01); In control group, there was no significant difference between prevaccination and postvaccination about MLR and peripheral T cell apoptosis. ConclusionT cell vaccination is capable of inducing Agspecific immune tolerance, the T cell apoptosis of peripheral blood induced by T cell vaccination may result in the depletion of Agspecific reactive T cells, which is vital in inducing specific immune tolerance.
