Journal of Interventional Radiology 2004;0(S2):-
Objective To compare between conventional and endoscope-assisted greater saphenous vein harvesting and to invest if endoscope-assisted greater saphenous vein harvesting can reduce post-operative leg incision complications.Methods Minimally invasive endoscopic saphenous vein harsvesting technique has been used in 36 isolated CABG patients and this is compaired with 50 conventional saphenous vein harsvesting group. There is no significant difference in sex structure, age, hypertension, diabetes mellitum (DM), myocardial infarction (MI) et al in two groups. Results The incidence of post-operative leg complications with minimally invasive greater saphenous vein harvesting group (2.8% ) was remarkably lower than that in conventional group (28%), and the hospital-stay time was much shorter in minimally invasive group. Conclusion Endoscope-assisted saphenous vein harvesting is a effective method in reducing post-operative leg incision complications.

Method: Two hundreds cases of chronic prostatitis were randomly divided into the treatment group and control group, 100 cases in each group, to observe the therapeutic effects in the clinical symptoms before and after acupuncture treatments and compare the therapeutic effects of the acupoints between the two groups. Results: Clinical subjective symptoms and examination of prostatic fluid were obviously improved in the treatment group (Group Ⅰ) than in the control group (Group Ⅱ), and the effective rate was 100% in the treatment group and was 91% in the control group, in a significant difference (P < 0.01).Conclusion: There is a remarkable therapeutic effect in the treatment of chronic prostatitis by puncturing four acupoints at the root of penis in combination with related acupoints.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Corynebacterium glutamicum SA001 is a mutant with lactate dehydrogenase (ldhA) deletion. In order to increase metabolic flux from isocitrate to succinate, and to improve the production of succinate under anaerobic conditions,we transducted the gene aceA coding isocitrate lyase (ICL) from Escherichia coli K12 into Corynebacterium glutamicum SA001 (SA001/pXMJ19-aceA). After 12 h aerobic induction by adding 0.8 mmol/L of IPTG, the recombinant strain was transferred to anaerobic fermentation for 16 h. Succinate reached 14.84 g/L, with a productivity of 0.83 g/(L x h). Compared to C. glutamicum SA001, the activity of ICL of the recombinant strain was increased 5.8-fold, and the succinate productivity was increased 48%. Overexpression of isocitrate lyase will increase the metabolic flux of glyoxylate bypass flowing to succinate.

AIM: To compare the clinical outcomes of pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells to treat and prevent the recurrence of pterygium.METHODS: Fifty patients (60 eyes) were divided into 2groups, and pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells (group A) and pterygium excision followed by transplantation of conjunctiva autograft harvested from counter-side limbus with stem cells (group B) were performed respectively.The surgical time of each case was recorded.RESULTS: All the 50 cases (60 eyes) of pterygium were recruited. The epithelization of cornea and conjunctiva in all cases finished in 2-5d, During the follow-up of 6-12mo, pterygium reoccurred in 2 cases (1 in each group), with no difference in recurrence rate. The mean surgical time was 25± 8min for group A,43± 11min for group B, the difference being statistically significant (P<0.05, t-test).CONCLUSION: Both methods, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells are effective on treating and reducing the recurrence of pterygium. Compared with the latter, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells is simpler and easier to perform, and is preferred by the patients too.

In order to investigate the effect of malic enzyme on anaerobic mixed acid fermentation,the gene encoding NAD+-dependent malic enzyme was amplified from E.coli DH5? genome by using PCR and cloned into vector pTrc99a to give an expression vector pTrc99a-sfcA.Malic enzyme was overproduced by E.coli FMJ39(ldh,pfl)harboring pTrc99a-sfcA under the condition of IPTG induction.The results of anaerobic fermentation indicated overexpression of malic enzyme would have influence on the pathway of formate,acetate and succinate of FMJ39.The concentration of formate and acetate was 17.58% and 15.27% higher than FMJ39,the succinate concentration was reduced by 26.87%.There was no obvious citrate concentration change.The experimental results also indicated that high concentration of L-Thr and L-Ser would induce the Tdc operon to convert pyruvate into formate and acetate even when pfl gene encoding the pyruvate formate lyase was inactivated.
