In-stent restenosis after interventional treatment remains an unsolved and important clinical problem. The proliferation and migration of arterial smooth muscle cells are key events frequently followed by vascular restenosis after angioplasty and continuous inflammation may also be the other important factor for the restenosis after stenting. Study of the pathogenesis of restenosis may find some potentially novel therapeutic pathways for attenuating in-stent restenosis.

Objective:To investigate the super selective transhepatic arterial embolization (TAE) for effects of cyst volume and liver function in patients with symptomatic polycystic liver disease (PLD), and provide a reliable basis for clinical diagnosis and treatment. Methods: 14 cases of symptomatic patients with PLD were selected from October 2014 to October 2015 in our hospital using super selective hepatic arterial embolization. The upper abdomen was performed CT scan one year after surgery, and the volume of patients with liver cyst was tested. We observed the changes of total volume of liver before TAE and postoperative kidney function, adverse reactions, and the improvements after four months’ follow-up.Results: The angiography for the 14 patients showed liver volume increased in different degrees. It also showed that blood supply was mainly hepatic artery wall branch. There were different sizes of liver round unstained area. There was consistent between CT examination and unstained area in polycystic liver swollen area. The difference of the total volume of the liver cyst was statistically significant in 14 cases of the patients with PLD before TAE treatment and after 12 months’ treatment (t=2.8627,P<0.05). 14 cases of the patients with PLD after TAE before treatment and after 1 week’s laboratory tests, the difference was not statistically significant among AST, ALT, ALB and TBIL (t=0.0441,t=0.3316,t=0.0722,t=1.9855;P>0.05). Compared with the preoperative, there was little effect on liver function by TAE. After 3 to 12 months, symptoms gradually improved and physical rating increased. The improvement rate was 100% after 12 months and the physical score was from 90 to 100 points. The embolism syndrome in 14 cases of patients gradually disappeared after 1 to 5 days, and five days later the symptoms disappeared. Conclusions: There is a significant effect for symptomatic polycystic liver patients with TAE. It can improve efficacy and reduce patient suffering with a low recurrence rate. It is worthy of clinical application.

Objective To investigate the expression of E-cadherin(E-cad)and the relationship with the Lauren classification,the degree of histological differentiation,the clinical stage,the depth of invasion,lymph node metastasis and distant metastasis of gastric cancer. Methods 80 cases architecture of gastric cancer and normal tissue were collected.The expression level of E-cad in 80 cases of gastric carcinomas and their metastatic lymph node tissues were examined by immunohistochemical assays.Results The expression rate of E-cad in 80 cases of gastric carcinomas Was 55.00%.The expression level of E-cad was positively correlated with the Lauren classification,the degree of histological differentiation,the clinical stage,the depth of invasion,lymph node metastasis and distant metastasis(P＜0.05),but Was not correlated to patients sex,age and tumor size.The expression rates of E-cad in metastatic gastric carcinoma of primary lesions and lymph nodes metastasis were 35.48%and 32.26%. respectively. Furthermore, E-cad expression in metastatic gastric carcinoma was significandy correlated with primary lesions and lymph node memstasis(r=0.4978,P＜0.05).Conclusion The expression level of E-cad in gastric carcinoma Was closely correlated with the degree of tumor differentiation,infiltration and transferring.

A study on abdominal skin flaps of the fresh cadavers of young men under the operation, light and scanning electron microscope, and MAS image analysis system has been made. Methods include Chinese ink, ABS or methyl methacrylate injection and histological slides, transparent specimens as well as casts preparation. The course of the vessels in the human abdominal skin flap is in the "three steps form". Trunks and main branches of the cutaneous vessels run in the deep part of the superficial fascia, their branches and terminals form anastomoses in the middle of the reticular layer of dermis, and branches from the anastomoses form microvascular network in the subpapillary layer. The vascular networks in the skin flap are concentrated in five layers: the deep fascial, superficial fascial, profund dermal, subpapillary, and papillary layers. Between the subpapillary and the profund dermal vascular networks, there is a layer devoid of vascular network and crossed by vascular arteries only. Therefore, this layer may be called as "vascular network devoid area". The differences of the area fraction (Aa) or number of vessels are not significant among various areas of the abdominal skin flap. Design in detaching the abdominal skin flaps and skin grafts is discussed.

AIM:To investigate the effect of lipopolysaccharides(LPS)preconditioning on CCl4-induced liver injury and the change of LPS signal transduction.METHODS:The male Wistar rats were divided randomly into liver-injury group,which were injected with CCl4 5 mL/kg first,three days later were injected 0.3 mL 40% CCl4 and 60% olive oil. Animals in LPS preconditioning group were injected with LPS 0.5 mg/kg before the day CCl4 was given. Rats received high fat diet were as liver injury group,and normal control group received normal diet. The lymphocytes infiltrated in the liver tissue were counted. The endotoxin and ALT level in rat plasma,TNF-? content and expressions of TLR4,p38,p-p38,I??,NF-?? in the rat livers were also determined.RESULTS:The lymphocytes in liver slice and ALT level of the plasma in LPS preconditioning group were lower significantly than those in the liver injury group,and the expressions of TLR4,p-p38,NF-?? in the liver were the same. In contrast,the expression of I?? was higher.CONCLUSION:LPS preconditioning relieves obviously CCl4-induced chronic liver injury. The mechanism may be associated with change of signal transduction of LPS,which results in decrease of pre-inflammatory cytokines.

Objective To evaluate the effects of stepwise and fine-grained dietary management on the diet control of liver cirrhosis patients complicated with gastrointestinal hemorrhage. Methods Eighty liver cirrhosis patients complicated with gastrointestinal hemorrhage were assigned to experimental group (41 cases) and control group(39 cases) by random digits table method. The patients in experimental group were treated with stepwise and fine-grained dietary management and the patients in control group were given conventional dietary treatments. The compliance diet, mastery of nutrition knowledge, malnutrition risk at admission, intake food, discharge and 2 months after discharge between two groups were monitored. The incidence of rebleeding was tracked after 1 year of discharge. Results The incidence of malnutrition risk in Child-Pugh class C was higher than that in Child-Pugh class B( Z=-4.3, P<0.05 ) . The incidence of malnutrition risk in patients with high education level was lower than that in patients with lower education( r=-0.453, P<0.05 ). The experimental group significantly outperformed control group in mastery of nutrition knowledge at discharge:80(70, 84) points vs. 52(42, 64) points, in compliance diet and malnutrition risk after 2 months after discharge:86(76, 91)%vs. 53(46,57)%, 1(1, 2) points vs. 2(1,3) points, the rebleeding rate in experimental group was significantly less than that in control group within 1 year after discharge 14.6%(6/41) vs. 35.9%(14/39), and the differences were statistically significant between two groups ( χ2 = 4.226- 51.232, all P < 0.05 ). Conclusions Stepwise and fine-grained dietary management can improve the mastery of nutrition knowledge, compliance diet and nutritional status, and reduce the occurrence of rebleeding, worth popularizing further in clinical care of liver cirrhosis patients complicated with gastrointestinal hemorrhage.

Objective To improve the success rate of insertion of gastric lavage canal in patientswith tracheal intubation. Methods 70 patients with organophosphoms pesticide intoxication who neededgastric lavage after tracheal intubation were randomized into the test group and the control group, 35 easesin each. In test group, lavage canal was inserted through bite block orally and the bedside was raised till 70to 80 in angle. While in the control group, lavage canal was inserted directly through mouth with the posi-tion of hypsokinesis. The success rate of intubation was compared between the two groups. Results One-time success rate was 94.2% in the test group,which was statistically different from that of the control group(37.1%), P < 0.01. The complication of intubation in the test group was also lower than that of the controlgroup,which had statistical difference. Conclusions Through improvement of position to raise the bedsidetill 70 to 80 in angle, the insertion of gastric lavage canal through bite block orally was much better than thenormal one and it is worth applying.
