Objective To investigate the effect of L-N6-(1-iminoethyl) Lysine(L-NIL) on ischemia-reperfusion (I/R) -induced lung injury in a rat model of lung transplantation. Methods Pathogen free male SD rats weighing 250-350g were used as donor and recipient rats in this study. The animals were randomly divided into 3groups (n = 6 each): sham operation group (group S); lung tratsplantation group (group L) and lung transplantation + L-NIL (selective iNOS inhibitor) group (group L-NIL). In group L and L-NIL orthotopic left lung allograft transplantation was performed. In group L-NIL 3 mg/kg was injected iv at the beginning of reperfusion. The donor lungs were removed from live donor rats and placed in Euro-collins solution at 4 ℃. The lung transplantation was performed under microscope and non-suture cuff technique was used. The implanted donor lungs were ventilated and reperfused. 0.5% Evans blue 0.2 ml was injected iv during reperfusion. The donor lungs were removed after being implanted, ventilated and reperfused for 2 h for microscopic examination and determination of iNOS, endothelial NOS (eNOS) and myeloperoxidase (MPO) activity and malondialdehyde (MDA) and Evans blue content in the lung tissue and W/D lung weight ratio. Results Lung transplantation significantly inceased W/D ratio, iNOS and MPO activity, and Evans blue and MDA content in the lung tissue and decreased eNOS activity in group L as compared with group S. L-NIL iv significantly attenuated the increase in the variables mentioned above and ameliorated capillary congestion and inflammatory cell infiltration in the lung. Conclusion Intravenous L-NIL administered at the beginning of reperfusion can reduce I/R injury to the transplanted donor lungs.

Aim In order to provide the experimental basis to investigate the pathologic mechanisms and drug treatment of pulmonary fibrosis,establish the lung slice fibrosis model induced by transforming growth factor-?_1 (TGF-?_1) . Methods Lung was isolated and inflated with 0.4 % agarose solution, then was cut into slices. The lung slice viability was assessed through lactate dehydrogenase (LDH) leakage and MTT assay after incubation of 1, 3, 5, 7, 9 days. The sub-optimal time and dose of TGF-?_1- induced lung slice fibrosis were investigated via measurement of hydroxyproline (HYP), and lung slice fibrosis was examined with HE and Masson staining. Results The lung slice was viable for up to 9 days. The sub-optimal time and dose of TGF-?_1-induced lung slice fibrosis were 7 days and 2.5 ?g?L~ -1 respectively. Meanwhile, hydrocortisone did not decrease the HYP levels in lung slices of TGF-?_1-induced fibrosis. Conclusion TGF-?_1 (2.5 ?g?L~ -1 ,?7d) induced lung slice fibrosis, and hydrocortisone did not exert advantageous effect on this process.

Objective To compare the short-term results of rectal cancer treated either by laparoscopic or open total mesorectal excision(TME). Methods A series of 165 unselected consecutive patients with rectal cancer from August 2002 to December 2005, who decided to accept the laparoscopic or open TME, were included in this study. The following parameters were compared between the two groups: length of the surgical specimen, distance between the distal incisal edge of the rectum and the inferior margin of the tumor, the number of the lymph nodes resected, local recurrence rate, incidence of distant metastases, and 2 year survival rate. The mean follow-up period for both groups was 26.9 months (range, 6-46 months). Results Demographic data and Dukes stage were matched in two groups. The mean length of the resected specimens was 24.4 cm in the laparoscopic TEM group and 25.2 cm in the open TEM group. The distance from the distal incisal edge of the rectum to the inferior margin of the tumor was 2.9 cm in the laparoscopic TEM group and 2.7 cm in the open TEM group, and the mean number of lymph nodes scavenged was 11.5 in the laparoscopic TEM group and 10.6 in the open TEM group. The local recurrence rate after laparoscopic resection was 9.6%, as compared with 11% after open resection. Distant metastases occurred in 11.5% of the patients in the laparoscopic group, whereas it was 14.6% in the open group. Two year survival rate was 85.7% and disease free survival was 76.2% after laparoscopic resection and compared to 78.8% and 69.7% after open resection. All above parameters did not show statistically different between the two groups. Conclusion The oncologic resection and the early outcomes are comparable between the two surgical approaches.

Objective To observe the therapeutic efficacy of acupuncture at myofascial trigger points (MTrPs) in treating cervical spondylosis of vertebral artery type. Methods Ninety-eight patients with cervical spondylosis of vertebral artery type were randomized into a treatment group of 51 cases and a control group of 47 cases. The treatment group was intervened by acupuncture at the MTrPs, while the control group was by injection of medical solution for anti-inflammation and analgesia. The positive rate of rotate-cervix test, dizziness score, and visual analogue scale (VAS) of the head and neck pain were compared before and after intervention. Results After intervention, the positive rate, dizziness score, and VAS score were significantly changed in both groups (P＜0.05). There were significant differences in comparing the positive rate, dizziness score, and VAS score between the two groups after intervention (P＜0.05). The total effective rate was 96.1%in the treatment group versus 76.6%in the control group, and the difference was statistically significant (P＜0.05). Conclusion Acupuncture at the MTrPs can improve the dizziness and head-neck pain in patients with cervical spondylosis of vertebral artery type.

BACKGROUND:The endothelial dysfunction is the pathogenesis of arteriosclerotic disease, the quantity and function of endothelial progenitor cells are decreased within the cycle, leading to a poor capacity of neovascularizatio, the efficacy of stem celltransplantation alone is unclear, the combination of cytokines and gene-modified stem cells is the hotspot.
OBJECTIVE:To observe the effect of stromal cel-derived factor-1 on the neovascularization after endothelial progenitor cells transplantation.
METHODS:Unilateral hindlimb ischemia model was established in 20 athymic nude mice, and the mice were randomly divided into four groups:combined group (intravenous endothelial progenitor cells+intramuscular stromal cel-derived factor-1), endothelial progenitor cells group (intravenous injection of endothelial progenitor cells), stromal cel-derived factor-1 group (intramuscular injection of stromal cel-derived factor-1), and blank control group (intramuscular M199). The skin temperature of ischemic hindlimbs and survival of animals after transplantation were observed. The ratio of capil ary/skeletal muscle fiber was counted. The expression of CD31 and endothelial nitric oxide synthase were detected.
RESULTS AND CONCLUSION:The fluorescence-labeled endothelial cells were embedded in ischemic hindlimb muscles after celltransplantation. Of the 20 nude mice, two mice died. The rate of ischemic hindlimb reserving was respectively 80%, 75%, 20%and 0 in combined group, endothelial progenitor cells group, stromal cel-derived factor-1 group, and blank control group. The capil ary/muscle fiber ratio in combined group and endothelial progenitor cells group was higher than that of blank control group (P<0.01). The combined group was greater than endothelial progenitor cells group, and endothelial progenitor cells group was greater than stromal cel-derived factor-1 group (P<0.05). The capil ary density in combined group and endothelial progenitor cells group were higher than that in blank control group (P<0.01), and stromal cel-derived factor-1 group was also more than blank control group (P<0.05). The combined group was greater than endothelial progenitor cells group, and endothelial progenitor cells group was greater than stromal cel-derived factor-1 group (P<0.05). The positive rate of endothelial nitric oxide synthase was 73.33%and 53.33%in combined group and endothelial progenitor cells group respectively (P>0.05). Endothelial progenitor cells can migrate to ischemic tissues, endothelial progenitor cells transplantation can promote neovascularization, and stromal cel-derived factor-1 augments the neovascularization after celltransplantation, in which endothelial nitric oxide synthase is involved.

Objective To evaluate immediate breast reconstruction with extended latissimus dorsi flap after mastectomy for patients of breast cancer. Methods One hundred and sixty-two women with breast cancer underwent surgery from Jan, 2000 to Dec, 2007. Masteetomy was carried out including traditional modified mastectomy in 32 cases, skin sparing mastectomy in 51 cases and nipple-areolar sparing mastectomy in 79 cases. Immediate breast reconstruction was performed with latissimus dorsi flap and surrounding fat tissue. Results Operation was successful in 161 cases. The morphology of reconstructed breasts was excellent in 91.93% cases as evaluated by patients themselves. After operation 6 cases had partial nipple necrosis, 5 cases had rhacoma of the chest, but cured conservatively. Eleven cases had seroma on the back, among them 8 cases cured by puncture and drainage. Two cases cured by erasion of the pseudomembrane and 1 case cured by exairesis of the fibrous capsule. Three cases had limited skin necrosis around the incision. One case had necrosis on part of the donor side, cured by reoperation. One case had implant necrosis necessitating removal of the implant. The patients were followed up for 7～90 months, and the 23 cases were free of tumor recurrence before they lost to follow-up. Among those followed-up cases there were bone metastasis in 2 cases, lung metastasis in 1 case and supra clavicular lymph node metastasis in one. No local recurrence was found. Conclusions Immediate breast reconstruction with extended latissimus dorsi flap after masteetomy is safe and effective, especially suitable for small and medium size breasts.
