BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87% in the ENOTES group, which was statistically different from 78.12% in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Ribavirin is a broad-spectrum antiviral agent and glycyrrhizin has activities of anti-inflammation, immunoregulation and anti-viral infections. To enhance antiviral efficacy and weaken side-effects of ribavirin, antiviral effects of the combination of glycyrrhizin and ribavirin were studied in the present study. Firstly, a mouse model of viral pneumonia was established by inoculation of influenza H1N1 virus. Protective effects of glycyrrhizin and ribavirin used alone or in combination against H1N1 virus infection in mice were evaluated based on the survival rate, lung index and virus titer in lungs of mice. Results showed that the combination of glycyrrhizin and ribavirin significantly inhibited the lung consolidation with a 36% inhibition ratio on the lung swell of infected mice. The combination of the two drugs exhibited synergetic effects on survival of infected mice. The combination of 50 mg · kg(-1) · d(-1) glycyrrhizin and 40 mg · kg(-1) · d(-1) ribavirin resulted a 100% protection for infected mice with a synergetic value of 36, which was significantly higher than the control group and each drug alone. This combination also resulted a significant drop of lung virus titer (P < 0.01), as well as inhibition on the production of proinflammatory cytokines IL-6 (P < 0.01), TNF-α (P < 0.01) and IL-1β (P < 0.05) induced by virus infection compared to the control. The treatment of ribavirin plus glycyrrhizin was more effective in influenza A infection in mice than either compound used alone, which suggested a potential clinical value of the combination of the two agents.

In order to study the relationship between the expression of glutathione S-transferase (GST) in leukemic cells and the chemoresistance in patients with acute leukemia, the expressions of GST activity and GST mRNA were measured according to spectrophotometric assay based on the use of 1-choloro-2, 4-dinitro benzene and in situ hybridization. The results were studied in correlation with some clinical and pathological data. Results showed that: 1. There is no significant differences between activities of the enzyme with the different leukemia types according to the FAB classification. 2. GST activity and GST mRNA expression in the patients, both untreated and relapse, were (4.5 +/- 1.0) U, 33.3% and (7.9 +/- 15) U, 66.3% respectively. 3. In 56 patients, GST activity was 1.7 +/- 0.7, 5.9 +/- 2.0 and 9.3 +/- 1.7 U and GST mRNA expression was 13.3%, 29.7% and 76.6%, respectively, in CR, PR and NR groups. The lowest values of GST activity and GST mRNA expression were observed in those patients who achieved complete remission. The highest values of GST activity and GST mRNA expression were observed in those patients with no response to treatment. It was concluded that the expression of GST in patients with acute leukemia is closely related to the chemosensitivities clinically. Determinations of GST activity and GST mRNA are useful for predicting the chemosensitivities and the prognosis of the disease.
