Objective To evaluate the clinical effect of artificial liver support system (ALSS)on serum high -sensitivity C -reactive pro-tein (hs -CRP)level and investigate the influence of the change in hs -CRP level on clinical prognosis among patients with hepatic failure. Methods Patients were recruited into three groups:group one included 60 patients who received ALSS due to hepatic failure;group two in-cluded 37 patients with hepatic failure without ALSS treatment;and group three included 37 patients with chronic hepatitis B.The serum levels of hs -CRP were measured in groups two and three,and in group one before and after ALSS treatment.Comparison of continuous data between groups was made by t test,and comparison of categorical data was made by chi -square test.Results The levels of hs -CRP in group one before treatment and in groups two and three were 12.89 ±9.39,12.22 ±9.73,and 2.83 ±6.79,respectively.No significant difference in hs -CRP level between group one and group two was observed (P >0.05).However,the hs -CRP level in group three was significantly different from those in group one and group two (P <0.001 ).The improvement rate in group one after ALSS treatment (78.3%)was significantly higher compared with that in group two (54.05%)(χ2 =6.315,P <0.05).ALSS treatment (t =5.179,P <0.05).ALSS treatment was selectively effective in a subgroup of patients and greatly decreased the hs -CRP level in these patients (t =5.344,P =0.000),resulting in a significant difference from the patients who were unresponsive to ALSS treatment (t =2.368,P =0.038).Conclusion Artificial liver support system can decrease the hs -CRP level in patients with hepatic failure.Serum level of hs -CRP can be used as a clinical indicator of disease progression and predict the clinical outcomes of ALSS in patients with hepatic failure.

Objective:To observe the clinical efficacy of the combination of montelukast, budesonide nasal spray and deslorata-dine citrate disodium in the treatment of allergic rhinitis and its influence on inflammatory cytokines. Methods:Totally 94 cases of al-lergic rhinitis patients received treatment in our hospital were selected and divided into the observation group and the control group ran-domly. The control group received budesonide nasal spray and desloratadine citrate disodium, and the observation group received mon-telukast additionally. After 4-week treatment, the changes of clinical symptoms and the contents of IL-6, IL-8 and IL-10 in the two groups were compared. The clinical efficacy of the two groups was also compared. Results:After the treatment, the VAS score of the nasal symptom and category symptoms in the two groups were lower than that before the treatment, and the score of the observation group was lower than that of the control group (P<0. 05). After the treatment, the contents of IL-6 and IL-8 were significantly re-duced while the content of IL-10 was significantly increased in the two groups, and the changes in the observation group were more no-table than those in the control group (P<0. 05). The total effective rate of the observation group was 91. 49%, which was higher than that of the control group (80. 85%, P<0. 05). Conclusion:The combination of montelukast, budesonide nasal spray and deslorata-dine citrate disodium can significantly improve the clinical symptoms, reduce the IL-6 and IL-8 levels and increase the IL-10 content in allergic rhinitis patients.

Objective To report our experience on video-assisted thoracoscopic surgery(VATS)and perioperative management for patients over 70 years old.Methods From May 1998 to May 2008,78 patients over 70 years old were treated by VATS.Operative risk was evaluated by measuring forced expiratory volume in first second(FEV1),diffuse capacity of carbon monoxide(DLCO),and left ventricular ejection fraction(LVEF),and artery blood gas analysis and exercise test before the operation.VATS(n=46)or video-assisted minithoracotmy(n=32)was carried out under general anesthesia with a double-lumen tube.Extubation was delayed in 11 patients after the procedures and mechanical ventilation was employed to smooth anesthesia recovery.Results Postoperative pathological examination showed primary lung cancer in 20 cases,benign pulmonary lesions in 26,pleural mesothelioma in 3,malignant pleural metastasis in 5,empyema in 5,benign mediastinal tumor in 15,hiatal hernia in 3,and esophageal leiomyoma in 1.Postoperative morbidity was 33.3%(26/78)in this series,none of the patients died during the operation;the perioperative mortality was 2.6%(2/78).Conclusions VATS is safe for elderly patients.Satisfying outcomes can be achieved through strict preoperative evaluation,proper operative method and active management for postoperative complications.

0.05). Sixteen patients in the video-assisted thoracic surgery group were followed up for a mean of 42.9 months (20-88 months), during which no recurrence was detected. In the minithoracotomy group, 18 patients received an 18-to 71-month follow-up (mean, 41.2 months), none of them had recurrence. Conclusions The outcomes of both the operations are satisfying for middle-aged or elderly patients with spontaneous pneumothorax. However, video-assisted thoracic surgery should be the first choice.

Objective To evaluate the effects of hydroxyethyl starch (HES) on the renal function and blood coagulation of patients with acute pancreatitis (AP). Methods 151 patients with acute pancreatits were divided into treatment group (treated with HES, n=62) and control group (treated with crystalloid solutions, n =89). The two groups were compared by retrospective analysis of the indices such as serum creatinine (Scr), blood urea nitrogen (Bun), platelet count(Plt), prothrombin time activity (PTA), international normalized ratio (INR), activated partial thromboplastin time (APTT) and fibrinogen (FIB) before and after treatment. Results Before hospitalization, there were insignificant differences in respect of Scr and Bun in the two groups respectively. But at discharge, Scr and Bun in the treatment group were significantly increased (P<0.05), while Bun was significantly decreased 24 h right after infusion of crystalloid solutions in the control group (P<0.05). There were no differences between the two groups in terms of Scr and Bun. As for indices of coagulation, APTT in the treatment group was significantly increased after infusion of HES (P<0.05). The hospital stay in the treatment group was longer than the control group (P < 0.05). Conclusions HES may adversely affect renal function and intrinsic pathway of blood coagulation of patients with AP. Renal function and blood coagulation should be monitored when using HES.
