Chinese Journal of Minimally Invasive Surgery 2001;0(06):-
Objective To explore the feasibility of two-port laparoscopic drainage in the treatment of liver abscess. Methods A total of 18 patients with bacterial hepatic abscess underwent twoport laparoscopic drainage.Two incisions were made at the superior border of the umbilicus and 4~5 cm below the right costal margin near the anterior axillary line,respectively.The abscess was cut through in "┼" or "╫" shape.The pus cavity was debrided bluntly,and a double-lumen drainage tube was placed.Results The laparoscopic drainage was performed successfully in all the 18 patients.The operative duration was 30~75 min(mean,45 min).A bile leakage for 80~100 ml per day occurred in 1 patient.The drainage tube was removed on the 12th postoperative day and the patient was discharged from hospital on the 14th postoperative day.Of the 18 patients,the hospital stay after operation was 7~14 d(mean,8.5 d).All the patients were followed for 5~12 months(mean,9 months) and no residual abscess or recurrence was found. Conclusions Two-port laparoscopic drainage for liver abscess is an ideal approach with advantages of simple manipulation,slight contamination inside abdominal cavity,little trauma,low complication rates,and rapid recovery.

AIM: To investigated the changes of hippocampus noradrenaline levels and its tyrosine hydroxyase (TH) , monoamine oxidase A (MAOA) expressions during chronic psycological stress procedure and physical exercise in rats. METHODS: Male Wistar rats (n =24) were randomly assigned to three conditions; (1) restraint stress (S) at 6 h/d for 3 weeks; (2) 24 h access to activity wheel running (E) for 4 weeks; (3) a sedentary control group (C). Levels of NE were assayed by high performance liquid chromatography with electrochemical detection. Protein expression of TH and MAOA were detected by Western blotting. RESULTS: Compared to C, weight loss and sucrose consumption rate decrease were induced in S, and NE was lower while TH and MAOA expressions increased significantly. In E group, NE was higher and TH, MAOA increased distinctly. CONCLUSION: It is suggested that hippocampus NE level may play an important role in the mechanism on the protection of physical exercise to chronic psycological stress, there is no close connection between NE change and TH, MAOA.Other mechanisms may exist.

AIM: This study is to determine changes of hippocampal norepinephrine (NE) and serotonin (5 -HT) in long term physical exercise and chronic psychological stress, and to study the roles of the two monoamine transmitters in the effect of exercise counteracting stress - induced hippocampal damages in brain. METHODS : Levels of hippocampal NE and 5 - HT in rats undergoing 4 - week voluntary wheel running exercise (exercise group) or 3 - week restraint stress (stress group) or 4 - week exercise and 3 - week stress (exercise - stress group) were detected by high - performance liquid chromatography using electrochemical detection. RESULTS: It is showed that levels of hippocampal NEand 5 - HT increased significantly (P < 0. 01) in the exercised rats, and in the stressed rats, hippocampal 5 - HT levelssignificantly decreased(P < 0. 05). Additionally, the NE levels maintained significant high (P < 0. 01) in exercise -stressed rats compared to the pure stressed ones. On the other hand, no obvious difference was observed in hippocampal5 - HT levels between stress group and exercise - stress group, which were all significant lower (P < 0. 05) than that in exercise group. CONCLUSION: It is suggested that both the NE and 5 - HT may play important roles in mediating the exercise-induced positive effects and the 5 - HT may play an important role in stress - induced negative effects on the hippocampus. Moreover, NE may take more action in the exercise attenuating stress - induced hippocampal damages. The hippocampal NE may be more susceptible to exercise, and the hippocampal 5 - HT may be more susceptible to stress.`

The aims of this research were to isolate a Aspergillus niger strain with higher beta-glucosidase activity. We utilized the beta-glucosidase producing strain Aspergillus niger CGMCC 3.316 as the original strain to first obtain a mutant 3-3M through ultraviolet irradiation. Then we studied the conditions of protoplast release and regeneration for strain 3-3M. We treated the protoplasts of strain 3-3M via ultraviolet irradiation and obtained another isolated mutant 60B-3D. The strain 60B-3D showed much higher beta-glucosidase production than the original strain and 3-3M strain. The beta-glucosidase activity of strain 60B-3D was 23.4 IU/mL, with an improvement of 39% compared with the original strain, and 23% compared with strain 3-3M. We also studied the fermentation process of strain 60B-3D, and compared it with the original strain and strain 3-3M. We found the strain 60B-3D exhibited an improvement in xylanase production. The comparison results also showed that the strain 60B-3D secreted more protein. These results were beneficial for producing beta-glucosidase through this productive mutant.
