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.

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 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.

Objective To investigate the clinical efficacy of fire needling plus moxibustion in treating prurigo nodularis. Methods Ninety patients with prurigo nodularis were randomly allocated to treatment and control groups, 45 cases. The treatment group received fire needling plus moxibustion and the control group, external application of halometasone ointment. Skin lesions and pruritus were scored in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the skin lesion score and the pruritus score in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the skin lesion score and the pruritus score between the treatment and control groups (P<0.01). The total efficacy rate was 81.8% in the treatment group and 60.5% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Fire needling plus moxibustion is an effective way to treat prurigo nodularis.

Objective To determine the effect of apoptosis in different host cells induced by L. in- terrogans and the associated intracellular signaling pathway. Methods L. interrogans serogroup Icterohaem- orrhagiae serovar icterohaemorrhagiae strain Lai infected cell models in mouse mono-macrophage like cell J774A. 1, human EVC304 cells and A549 cells were established, respectively. Flow cytometry with fluores- cein labeling of FITC-Annexin V/PI was performed to examine the apoptosis or necrosis of the infected cells. Fluorometry as well as Western blot assay was applied to measure the activity of caspase-3, -8, -9 and the expression levels of apoptotic associated protein FADD in the infected cells , respectively . Results 36.70%-63.70% of the L. interrogans strain Lai infected J774A. 1 cells displayed obvious early apoptosis during the infection for 1-6 h, and then altered to later apoptosis / necrosis (53.68%) as the major injury pattern when infected for 12 h. 78.52% of the L. interrogans strain Lai infected A549 cells only showed later apoptosis / necrosis. However, no obvious apoptosis and / or necrosis could be found in the L. interrogans strain Lai infected EVC304 cells. The maximal activities of caspase-3 and -8 in the infected J774A. 1 cells were (1453.41±36.07) and (1402.15± 59.09) FU, respectively, which were the 16.38-fold and 29.99- fold of those the non-infected cells. The caspase-9 activity of the infected J774A. 1 cells slightly increased [(89.42±5.08) FU ], which significantly lower than those of caspase-3 and -8 (P <0.001). The FADD expression level of the infected J774A. 1 cells was gradually increased in an infection time-dependent man- ner. Conclusion There is a distinct diversity of apoptosis in different cells induced by L. interrogans, and FADD→caspase-8→caspase-3 is the major signaling pathway to mediate L. interrogans infection associated cell apoptosis.
