Objective:To analyze influence of vaginal hysteroscopy and laparoscopic surgery on tubal pregnancy patients’ surgical outcome and inflammatory stress response.Methods: Chosen 86 cases of tubal pregnancy patients between July 2012 to July 2013 in our hospital undergoing surgery as study object, according to a random number table divided into hysteroscopy group (43 cases) and laparoscopic group (43 cases), compared surgical outcomes, perioperative differences in the level of inflammation and stress level.Results: No significant difference between hysteroscopy group and laparoscopic group on surgical success rate and ipsilateral tubal patency statistically(x2=0.241,x2=0.193;P>0.05), postoperative intrauterine pregnancy rate was higher than laparoscopic group, again ectopic pregnancy rate was less than laparoscopic patients(x2=7.294,x2=8.283;P<0.05); hysteroscopic surgery group E, Cor, IL-2, IL-6, IL-8, CRP levels were lower than laparoscopic group(t=6.842,t=6.283,t=8.536,t=6.106,t=6.283,t=6.376;P<0.05),TSH levels was higher than laparoscopic group(t=6.823,P<0.05).Conclusion:Vaginal hysteroscopy and laparoscopy can be used for the treatment of tubal pregnancy, hysteroscopy has an advantage in improving patient again intrauterine pregnancy, reduce postoperative systemic stress and inflammation levels, and promote the recovery of patients after surgery respect.

Objective: To analyze the effect of single-hole thoracoscopic surgical treatment on elderly spontaneous pneumothorax patients’ postoperative assessment and serological markers and explore single-hole thoracoscopic surgery application. Methods:78 cases of elderly patients with spontaneous pneumothorax were retrospectively analyzed, and divided into single-hole thoracoscopy group with 35 patients and conventional thoracoscopic group with 43 patients. Then the surgery indicators, postoperative pain scores and perioperative serum target level differences were compared between the two groups. Results: The operative time, postoperative drainage time and total hospital stays of single-hole thoracoscopic surgery patients were shorter than that of conventional thoracoscopic group. The differences were statistically significant (t=7.183, t=5.294, t=6.938;P<0.05). The blood loss and postoperative drainage were less. The differences were statistically significant (t=6.883, t=8.735; P<0.05). The postoperative pain scores within one week was less than conventional thoracoscopic group. The differences were also statistically significant (t=6.882, t=5.724, t=5.284;P<0.05). The serological indicators, CRP, IL-1, TNF-α,α1-AT levels of patients in the single-hole thoracoscopy group were lower than the conventional group (t=8.293, t=7.274, t=9.284, t=7.183;P<0.05). Conclusion:VATS and conventional hole thoracoscopic surgery can be used for treatment of spontaneous pneumothorax in elderly, but single-hole thoracoscopy has more advantages in reducing surgical trauma and postoperative pain and optimize systemic inflammation associated factors.

Objective To establish a patient-like human ovary carcinoma/spontaneous metastasis model using orthotopic transplantation of histologically intact tumor tissue. Methods An highly metastatic ovarian tumor line (8910PM: human serum carcinoma of the ovary) previously grown substaneously was transplanted into the ovicapaule using microsurgery technique. Histologically intact human ovary tumor pieces gained from implantation site were passaged between ovicapsules for four generations. Results All mice developed ovary tumors and the metastatic rates were about 50 %. The tumors only metastasized to liver. The earliest appearance of metastasis was 14 days and the average survival period was 20.7 ±4.89 days. The microscopic appearance of the metastases was similar to the tumor observed in the substaneous xenografts and orthotopically transplanted.Chromosomes analysis exhibited the feature of human carcinoma and retained genetic stability during the processes of passage. Conclusion Orthotopic implantation provides a suitable micro-environment in which ovarian cancer can express its intrinsic clinically-relevant properties. This approach is relevant to the spontaneous development of ovarian cancer and is thought to be a useful model for studies of metastatic mechanism and therapy for ovary cancer.

Objective To determine whether focal adhesion kinase (FAK) signal pathway was involved in migration of hepatocarcinoma cells by inhibiting focal adhesion kinase (FAK) phosphorylation in HepG2 cells with focal adhesion related nonkinase (FRNK). Methods The recombinant of FRNK and pEGFP-C2, an endogenous inhibitor of FAK activation,was transfected into HepG2 cells. HepG2 migration was examined by transmembrane assay. FAK and phosphatinositol 3-kinase (PI3-K) phosphorylation were detected by immunoprecipitation method. Confocal scanning microscopy was used to verify nuclear translocation of nuclear factor-kappa B (NF-?B). Results The transfection of FRNK recombinant plasmid could inhibit HepG2 migration, FAK and PI3-K phosphorylation decreased by 50.2 percent and 39.5 percent respectively. Furthermore, NF-?B translocation was down-regulated from 3.495?0.227 to 1.182?0.106. Conclusion These results suggested FAK was a main signal pathway in mediating HepG2 migration. Over expression of FRNK might inhibit signal transduction of FAK via depression of the phosphorylation of PI3-K and NF-?b activation, resulting in the decrease in migration of hepatocarcinoma cell.

Objective To explore the expression and significance of nestin in renal tubular epithelial cells in hypercholesterolemic rats. Methods Dietary-induced hyperlipidemia were induced in female SD rats by given 4% cholesterol and 1% cholic acid diet for 16 weeks. Changes of serum lipid, urinary albumin, serum creatinine and renal interstitial pathological changes were assessed. The expression of nestin and a-smooth muscle actin (α-SMA) were detected by immunohistochemical stain. Results The serum levels of total cholesterol, low density lipoprotein, urinary albumin and serum creatinine were significantly increased in hyperlipidemia group, accompanied with renal interstitial injury and fibrosis. As time extended, the expression of nestin and a-SMA in renal tubular epithelial cells were increased significantly. There was positive correlation among the expression of nestin and total cholesterol, low density lipoprotein, urinary albumin and serum creatinine( r =0.963,0.830,0.944,0.706, P <0.01). Nestin also had a positive correlation with tubular-interstitial index ( r = 0. 974, P < 0. 01) and α-SMA ( r = 0. 804, P < 0. 01). Conclusion The increased expression of nestin may be associated with renal tubular-interstitial fibrosis and tubular epithelial myofibroblast transdifferentiation in hypercholesterolemic rats.
