Purpose: To evaluate the feasibility of interventional biopsy, the component of stenotic tissues of shunt tract and mechanism of shunt stenosis. Materials and Methods: The pathologic specimens of stenotis shunt tract were obtained in 10 patients with catherization endovascular biopsy clamp and atherectomy methods, then they were undergone routinely with HE stain and immunocytochemical stain, and observed procedures under microscope. Rusults: all of interventional biopsy were succeeded without complication. The microscopies, findcarge of stenotic tissue were primarily composed of fibrotic granulations and thrombi with inflammatory cells and exuberant foam cells derived from endothelial cells, smooth muscle cells and rhagiocrine cells. Conclusion: 1)The interventional biopsy is a safe and effective method. 2)The stenosis in parenchymal tract is related to thrombosis and tissue orangnization.

Objective To explore the changes in fractional anisotropy (FA) among cerebral infarction pa-tients using MR diffusion tensor imaging (DTI), and to verify the relationship between any FA changes and functional recovery. Methods Thirty-eight cerebral infarction patients were divided into two groups according to their recovery level using Brunnstrom's criteria. All the patients accepted routine MR and DTI examination, and FA values were measured during the acute, subacute and chronic stages of their recovery. Results Average FA values in the lesion area were significantly lower than in the corresponding contralateral area, and were highest daring the acute stage.There was no significant difference between the subacute and chronic stages. Conclusions The FA values of cere-bral infarction patients change during the different stages of recovery with a certain regularity. This may be valuable for clinical treatment and prognosis.

Objective To evalute the feasibility of treatment for rabbit model with hepatic cirrhosis by transplantation of autologous bone marrow-derived stem cells via the hepatic artery and evaluate the effect of hepatocyte growth-promoting factors (pHGF) in the treatment of stem cells transplantation to liver cirrhosis.To provide empirical study foundation for future clinical application.Methods Chronic hepatic cirrhosis models of rabbits were developed by subcutaneous injection with 50% CCl4 0.2 ml/kg.Twenty-five model rabbits were randomly divided into three experimental groups,stem cells transplant group (10),stem ceils transplant + pHGF group (10) and control group (5).Autologous bone marrow was harvested from tibia of each rabbit,and stem cells were disassociated using density gradient centrifugation and transplanted into liver via the hepatic artery under fluoroscopic guidance.In the stem cells transplant + pHGF group,the hepatocyte growth-promoting factor was given via intravenous injection with 2 mg/kg every other day for 20 days.Liver function tests were monitored at 4,8,12 weeks intervals and histopathologic examinations were performed at 12 weeks following transplantation.The data were analyzed using analysis of variance Results Following transplantation of stem cells,the liver function of rabbits improved gradually.Twelve weeks after transplantation,the activity of ALT and AST decreased from (73.0±10,6)U/L and(152.4± 22.8) U/L to (48.0±1.0)U/L and(86.7±2.1)U/L respectively; and the level of ALB and PTA increased from (27.5 ±1.8)g/L and 28.3% to (33.2 +0.5)g/L and 44.1% respectively.The changes did not have statistically significant difference when compared to the control group(P >0.05).However,in the stern cellstransplant + pHGF group,the activity of ALT and AST decreased to (43.3±0.6)U/L and (78.7±4.0)U/L respectively and the level of ALB and PTA increased to (35.7 ±0.4)g/L and 50.5% respectively.The difference was statistically significant when compared to the control group(F=47.38,23.52,52.27,174.45,P < 0.05).In pathohistology,the degeneration and necrosis of hepatic cells and the degree of fibrous hyperplasia in stem cells transplant group were less obvious than that of the control group.Hepatic pseudo-lobules persisted.The improvement of liver architecture in the stem cells transplant + pHGF group was more evident than that in stem cells transplant only group.In addition,there were more hepatic CD34 <'+> cells within liver tissue in the stem cells trasplant group when compared to the control group,and the most hepatic CD34<'+> cells were seen in the stem cells transplant + pHGF group.Conclusion Autologous bone marrow stem cells transplanted via the hepatic artery for the rabbit hepatic cirrhosis model is an effective method to treat hepatic cirrhosis.The hepatoeyte growth-promoting factor can help to enhance the results of treatment.

Objective To investigate the value of MSCTA in diagnosing the origin of abdominal ectopic ovarian tumor. Methods Twenty-eight patients with 30 ectopic ovarian tumors that mainly manifested as abdominal lumps were evaluated with MSCTA retrospectively. Vascular three-dimensional reconstruction by VR based on add vessel (AV) and MIP was performed for all these patients after MSCT scanning.The origin of these tumors was judged by the feeding artery and ovarian vascular pedicle (OVP) sign.The result was compared with surgical findings.Results The maximum diameter of the 30 ectopic ovarian tumors ranged from 5.2 to 19.5 cm with an average of 9.3 cm.Of the 30 ectopic ovarian tumors, the ramus ovaricus arteriae uterinae (ROAU) and ovarian artery (OA) were demonstrated in 96.7% (29/30) and 56.7% (17/30) respectively.The feeding artery of the tumor was ROAU (29 cases) or OA (1 case), and OA participated in feeding the tumor in 16 cases.The accuracy rate of diagnosis of ectopic ovarian tumors according to the feeding artery was 100% (30/30).According to OVP the accuracy rate was 85.2% (23/27) with an incidence of 76.7% (23/30).Conclusion By showing ROAU and OA as the feeding artery and ovarian vein (OV) as the draining vein, MSCTA can accurately diagnose ectopic ovary tumors in the abdomen.

Objective To study the clinical significance of the change of plasma BNP levels in patients with grades sepsis and its correlation with the left ventricular ejection fraction.Methods One hundred patients of sepsis who were admitted in intensive care unit of Taizhou hospital were selected.It was divided into four groups:30 patients with septic shock,40 patients with severe sepsis,30 patients with sepsis and 20 persons without disease as control group.The concentration of plasma BNP was determined using sandwich immunoflurescence,and ultrasonic cardiogram was used to evaluate heart function and clinical features in all groups.To compare with the differences of the concentration of plasma BNP and the correlation between the concentration of Plasma BNP and LVEF in all groups,the data of clinical features,28-day mortality,prognostic values of BNP and the length of stay (ROG) in ICU were collected and compared.Result Plasma BNP levels in patients with septic shock[ (976.3 ± 160.7) pg/ml] were obvious higher than severe sepsis[ (648.4 ± 267.3) pg/ml ],sepsis [ (217.2 ± 89.7) pg/ml ] and control group [ (50.3 ± 25.4)pg/ml] (P ＜0.01).LVEF in patients with septic shock [ (48.2 ±9.6)% ] was obvious lower than severe sepsis[ (52.8 ±9.4)% ],sepsis[ (61.3 ± 8.9)% ] and control group[ (66.4 ±9.3)% ] (P ＜0.05 or P ＜0.01).It appeared to be inverse relationship between LVEF and the plasma BNP levels (r =-0.876,-0.724,P ＜0.01).BNP levels were significantly higher in non-survivors compared with survivors[ (1367.6±506.4)pg/ml vs (420.3 ±82.6)pg/ml,P ＜0.01 ].The receiver operating characteristic (ROG) curves indicated that values of areas under the curve of plasma BNP levels for 28-days mortality were 0.918(P ＜0.01).Conclusion The concentration of plasma BNP in patients was different in different grades of sepsis.It appeared to be negative correlation between the concentration of plasma BNP and LVEF.Plasma BNP levels had predictive value to the patients with sepsis.

Objective:To evaluate the prognostic value of sepsis-induced coagulopathy (SIC) in patients with sepsis.Methods:From January 2019 to December 2021, patients with sepsis admitted to the Intensive Care Unit of our hospital were retrospectively classified into the SIC group and non-SIC group according to SIC diagnostic criteria. The baseline clinical data, severity score, total length of hospital stay, length of ICU stay and 28-day survival were compared between the two groups. Kaplan-Meier was used to compare the 28-day survival of patients with sepsis between the two groups. Cox proportional hazard regression model was employed to analyze the risk factors of prognosis in patients with sepsis.Results:Totally 274 patients with sepsis were included in the analysis, including 139 patients in the SIC group and 135 patients in the non-SIC group. The two groups were compared in the perspectives of the Platelet count (PLT), prothrombin time (PT) , procalcitonin (PCT), D dimer, hematocrit, red blood cell distribution width, hemoglobin, acute kidney injury (AKI), the use of continuous renal replacement treatment (CRRT), the use of vasoactive drugs, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHEⅡ) score were compared between the two groups and the difference were statistically different (all P<0.05). Kaplan-Meier analysis showed that the 28-day mortality rate in the SIC group was significantly higher than that in the non-SIC group (32.4% vs. 14.1%, P<0.05). COX proportional hazard model showed that SIC score ( HR= 2.17, 95% CI: 1.15-3.91, P<0.05), APACHEⅡ score ( HR= 1.13, 95% CI: 1.09-1.17, P<0.05) and the use of vasoactive drugs ( HR=3.66, 95% CI: 1.53-8.75, P<0.05) were independent influencing factors for 28-day death in patients with sepsis. Conclusions:Patients with sepsis and SIC have more severe disease and increased mortality risk. SIC score exhibits good clinical value in predicting the prognosis of patients with sepsis.
