Objective To explore the role of splenectomy in the prevention and treatment of small-for-size liver in rat models, as well as its pathophysiologic mechanism in the development of a small-for-size syndrome (SFSS). Methods The models of sham-operation and 80 % partial hepatectomy (PH) were used in rats. In the experiment group splenectomy was performed following 80% PH. The concentrations of serum tumor necrosis factor (TNF-α), the content of NF-cB p65 in liver nuclear extracts, the expression of TNF-α, intercellular adhesion molecular (ICAM-1), and proliferating cell nuclear antigen (PCNA) transcripts, the activities of serum aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), total bilirubin (TB), albumin (Alb) cholinesterase (CHE), and liver myeloperoxidase (MPO) were analyzed. Portal venous pressures (PVP),incidence of SFSS,and one-wk survival rate were measured. Results In the control rats,The PVP was obviously elevated immediately after PH. The level of NF-κB p65 was obviously increased at the first h and peaked at about 3rd h postoperatively. The transcription of TNF-α and ICAM-1 and the release of serum TNF-α were significantly increased 3 h after PH. Capillary endothelial cells of the livers strongly expressed ICAM-1 24 h after PH. Splenectomy significantly reduced the PVP and the content of NF-κB p65 in the livers in concurrence with the expression of TNF-α and ICAM-1 gene as well as the activity of MPO at the corresponding time points after PH (P＜0. 05), while increased the expression of PCNA gene (P＜0. 05). Administration of splenectomy resulted in a statistically significant decrease in AST, ALT, LDH, TB, the incidence of SFSS and increase in one-wk survival rate (P ＜ 0.05 ). Conclusion Splenectomy alleviates liver injury and promotes liver regeneration in small-for-size liver rats by reducing portal vein perfusion and pressure,and suppressing NFκB activation and subsequent expression of proinflammatory mediators.

Objective To analyze the role of the introperative vessel Doppler sonographic evaluation of the hepatic artery and portal vein. Methods Intraoperative vessel Doppler sonograms of 116 patients were analyzed for peak systolic velocity of hepatic artery and blood flow of the portal vein.In patients having abnormal findings on sonography (peak systolic velocity of hepatic artery less than 30 cm/s, blood flow of the portal vein less than 800 ml/s), the vascular anastomoses were checked.Results Fourteen of 116 cases revealed less hepatic arterial peak systolic velocity than 30 cm/s. In 9 of the 14 cases, the hepatic arterial peak systolic velocity was normal after injection of 0. 5 % lidocaine into celic trunk root, and papaverine and 654-2 into artery, 3 of the 9 cases endured artery thrombosis. In the other 5 of the 14 cases, by-pass anastomoses were done, and the hepatic arterial peak systolic velocity was normal, and no hepatic arterial complication occurred. Five of 116 cases revealed less hepatic portal vein blood flow than 800 ml/rnin. 4 of the 5 cases revealed shunt between portal vein and vena cava. The blood flow was normal after ligation of the shunt, and thrombosis occurred in 1 case of the 4. The another 1 of the 5 cases was presented with portal vein thrombosis of grade m, and the blood flow remained lower than normal when side-to-side anastomosis was done after resection of thrombosis. Then vein by-pass of the superior mesenteric vein to portal vein with donor iliac vein was done, the blood flow became normal, and no complication occurred. Conclusions The vessel Doppler sonography during liver transplantation was of pivotal values in preventing and diagnosing vessel complications. For the patients with abnormal findings though intraoperative vessel Doppler sonography, the close monitoring should be done in order to find out vessel complication as

Background and purpose:The involvement of estrogen signaling in lung cancer is controversial. But the findings showed that ERβ might play an important role in neoplastic lung biology. Several studies have evaluated expression of ERβin both normal and neoplastic human lung tissues with variable conclusions. We aimed to evaluate the expressive of estrogen receptors (ER)α,βin non-smoking non-small cell lung cancer (NSCLC) and investigate the relationships between the survival and expressions of ERα,β. Methods:Immunohistochemical assay was used to detect the expression ERαand ERβin 144 NSCLC patients, and analyzed the expressions status of ERα,βand survival. Results:The positive rate of ERαwas 7.6%, only in adenocarcinoma cancer. The positive rate of ERβwas 52.1%, and the expressions of stageⅠandⅡwas signiifcantly higher than that of stageⅢandⅣ(P=0.020). The median survival time (MST) of ERβpositive expression was better than that of negative expression (43 months vs 38 months, P=0.028). The MST of ERβpositive expression of female patients was better than that of negative expression (45 months vs 37 months, P=0.033). The MST of ERβpositive expression of adenocarcinoma were 46 months and better than negative 38 months (P=0.021). Conclusion:The expression of ERβwas signiifcantly higher in early-stage non-smoking NSCLC. It indicated that the positive expression of ERβwas related to the better MST, especially in female adenocarcinoma patients.

Objective To investigate the relationship between human papillomavirus (HPV) infection and cervical lesions, and to explore the application value of HPV typing in cervical disease screening. Methods Colposcopic examination and cervical biopsy were performed in 1 851 cases of HPV positive patients from January 2017 to September 2018 in the cervical disease clinic of Shanghai First People's Hospital.Pathological diagnosis was used as the gold standard to analyze the distribution of HPV subtypes and the relationship between HPV subtypes and cervical lesions. Results Among 1 851 patients, high-risk human papillomavirus (HPV) infection was the main type.The detection rate of HPV 16 was the highest, followed by HPV52, HPV58, HPV53 and so on.A total of 234 patients with positive biopsy results were found, and 77 patients with CIN2 or above lesions were detected.The ratio of CIN2 or above patients with HPV 16 was 11.8% (45/380), higher than 2.4% (32/1 328) of other high-risk subtypes such as HPV52 and HPV58.The difference was statistically significant(χ²=61.60, P < 0.001).In the age factor, the high-risk positive ratio of HPV in the 35-year-old group was 96.91% (1 225/1 264), higher than 94.38% (554/587) in the 35-year-old group.The difference was statistically significant (χ²=6.898, P=0.009).The detection rate of CIN1 disease was 12.64% (234/1 851) in HPV classification test, 8.59% (159/1 851) in liquid based thin layer cytology test (TCT), and the detection rate of TCT as a screening method was lower than that of HPV test method (χ²=16.01, P < 0.001). Conclusion The survey find that HPV subtypes are the most common in the order of HPV16, HPV52, HPV58, HPV53 and HPV18.HR-HPV infection was closely related to cervical lesions, and with the increase of high-risk infections, the degree of cervical lesions also increased.The detection rate of HPV typing is higher than that of TCT screening for cervical lesions.HPV genotyping has high sensitive and negative predictive value in screening cervical lesions.

Objective To investigate AXIN2 mRNA expression level in hepatocellular carcinoma (HCC) , and to analyze the effect of AXIN2 gene methylation status on its mRNA expression and HCC genesis and development. Methods Fifty-three surgical excised HCC specimens and paired adjacent non-cancerous specimens, seven normal liver specimens and five HCC cell lines were collected. The expression of AXIN2 at mRNA level and the methylation status of AXIN2 gene promoter were determined by quantitative PCR. Results The expression of AXIN2 mRNA was lower in HCC tissues (0.1629 + 0.0679) than that in adjacent non-cancerous tissues (0. 4155 + 0. 2330), and there was significant difference (Z= -2. 567, P = 0. 010). The methylation level of AXIN2 gene in HCC and adjacent non-cancerous tissues (39. 77% ±3. 89%, and 36. 92% ±2. 81%) was significantly higher than that in normal liver tissues (7. 38% ±2. 40% , t=-3. 663 ,P = 0. 009;t= -4. 591 ,P = 0. 007).AXIN2 gene was hypermethylated in all five HCC cell lines. There was a negative correlation between AXIN2 mRNA expression level and the degree of methylation ( r = -0. 458, P = 0. 032). The methylation level was higher in TNM Ⅲ patients of HCC than that in TNM Ⅰ and Ⅱ patients (P =0.008). Conclusion The down-regulation of AXIN2 gene mRNA expression is correlated with its hypermethylation status. The low expression of AXIN2 mRNA and the abnormal methylation of promoter may be one of the important mechanism of HCC genesis and development.
