Objective To investigate the dynamic expression of SOCS-3, TNF-α in live and spleen of mice induced by AOPP, and to discuss the mechanism of MODS induced by AOPP, so that to give some intervention method over MODS in the future. Method Thirty-six adult BALB/c mice were divided into 3 groups randomly: AOPP group (n=12). Water normal group (n=12) and normal group (n=12). After post poison 2 hours, 6 hours, 12 hours and 24 hours,the fiver and the spleen tissue were taken out. The expression of SOCS-3 and TNF-α were detected by RT-PCR. And data were analyzed with ANOVA. Results After AOPP of 2,6,12,24 hours, the mRNA expression of SOCS-3 increased obviously in the liver and spleen compared with the normal group (P<0.05), it reached peak at the 24th hour in liver,and reached peak at the 12th hour in spleen, then descended at 24th hour (P<0.05). The mRNA expression of TNF-α increased obviously in the liver and spleen than normal group (P<0.05), and reached peak at the 12th hour,then descended at 24th hour (P<0.05), the electro-phoresis image of RNA was 5 s 15 s and 30 s,RT-PCR amplification of β-actin showed,the expression of SOCS-3, reached peak at the 24th hour in liver and it reached peak at the 12th hour in spleen, then descended at 24th hour (P<0.05), TNF-α reached peak at 12th hour in the liver and spleen, then descended at 24th hour. By statistic analysis, positive correlation was indicated among SOCS-3 and TNF-α mRNA expression in liver (y=0.089+0.758x, r=0.939, F=252. 168, P<0.01) positive correlation was indicated among socs-3 and TNF-α mRNA expression in spleen (y=0.057+0.361x,r=0.953,F=336.122, P<0.01). Conclusions At different point of time after Aopp,the mRNA expression of socs-3 and TNF-α showe the same trend in liver and spleen,the levels of SOCS-3, TNF-α all increase significenfly.

Objective To summarize our preliminary experience on diagnosis and treatment of aorta pseudoaneurysms due to deceleration injury. Methods Retrospective analysis was made on 8 cases of aorta pseudoaneurysms due to deceleration injury regarding its clinical findings, imagines and surgical operations or endografting treatment. Results Diagnosis was confirmed by imaging examinations. Among two cases who refused a surgery one died and the other lost follow-up after discharge. Surgery was successful in the remaining six cases including two cases treated by open surgery and four cases by intervensive endografting. Conclusions Aorta pseudoaneurysms due to deceleration injury can be correctly diagnosed by imaging examinations. Aorta pseudoaneurysms should be treated timely since spontaneous cure is almost impossible. Traditional surgical operations is effective, however, endografting is a relatively safe, less traumatic procedure.

Objective To evaluate therapeutic results of radiofrequency endovenous obliteration (RFO) for the treatment of varicose veins of the lower limbs. Methods Fifty six cases (56 limbs) of primary greater saphenous vein tributary varicose veins were randomly assigned to RFO group (n=28) and conventional stripping operation group (n=28). In RFO group, the wall of the greater saphenous vein was treated at 85℃ with the catheter to occlude the whole length of the vein. The other 28 cases underwent stripping procedure. The scattered superficial varicose veins in calf in both groups were managed by phlebectomy. The number of surgical incision, postoperative pain, average hospital days and the short-term results were compared. Results Patients in RFO group have less surgical incisions and less postoperative pain, without subcutaneous hematoma. The average hospital stay was 2.5?1.00 days in RFO group compared to 4.14?0.85 days in stripping operation group. Conclusions RFO effectively obliterates the whole length of the great saphenous vein and is of less trauma,faster recovery, and less scars.

Objective To investigate the expression of HSPA9 in hepatocellular carcinoma(HCC) and its relationship with clinicopathological features and prognosis.Methods Forty-nine cases HCC treated by operative resection and follow up data in our hospital from January 2006 to January 2010 were retrospectively analyzed.Immunohistochemistry was performed to determine the expression of HSPA9 in HCC and paratumor tissues.The relationship between HSPA9 expression and clinicopathological features and prognosis was statistically analyzed.Results The HSPA9 protein expression in tumor tissue was higher that that in the paratumor tissue(t=6.601,P＜0.01),moreover the over expression of HSPA9 was significantly correlated with lymph node metastasis (P =0.005),TNM-stage(P =0.015),tumor differentiation (P =0.033),microvascular invasion (P =0.009) and recurrence (P =0.047).In the survival analysis results,the patients with over expression of HSPA9 had a much lower total survival rate(P=0.002)and much higher postoperative cumulative recurrence rate(P =0.003).There were significant differences in TNM-stage,microvascular invasion,lymph node metastasis,tumor differentiation and HSPA9 staining for overall survival and cumulative recurrence rate based on a univariate analysis(P＜0.05).Conclusion HSPA9 has over expression in HCC.The over expression of HS-PA9 is closely related to invasion and metastasis pathological features and can serve as an independent prognostic risk factor for predicting the prognosis of HCC.

Objective To study the role of Th17 cells proportions and the cytokines levels in the diagnosis and treatment of acute pancreatitis (AP).Methods Patients with AP (n =82) treated in our hospital between August 2017 and August 2018 were divided into the mild AP group (MAP,n =36),the moderately severe AP group (MSAP,n =26) and the severe AP group (SAP,n =20).Twenty-five healthy subjects were chosen as the control group.The proportions of Th17 cells and the levels of cytokines including IL-17,IL-21,IL-22 and IL-23 in peripheral blood from the four groups were analyzed.The APACHE Ⅱ and Ranson scores were used to evaluate the illness severity.Spearman correlation analysis was conducted to detect the correlation between the Th17 cells,cytokines,and inflammatory factor,APACHE Ⅱ and Ranson scores.Results Compared with the control group,the proportion of Th17 cells and the levels of IL-17,IL-21,IL-22 and IL-23 in the peripheral blood of MAP,MSAP and SAP groups were significantly increased (SAP ＞ MSAP ＞ MAP,P ＜ 0.05).The levels of inflammatory cytokines IL-6,IL-8 and TNF-α,and the scores of APACHE Ⅱ and Ranson in the SAP group were significantly higher than those in the MSAP group and MAP group (P ＜ 0.05).The proportion of Th17 cells and their cytokine levels were positively correlated with IL-6,IL-8,TNF-o,APACHE Ⅱ and Ranson scores.The levels of Th17 cytokines returned to normal in AP patients after treatment.Conclusion Th17 cells and the cytokines have certain clinical significance in evaluating early inflammatory response,severity of illness,and therapeutic effect in AP patients.
