Objective To evaluate the curative effect of fallopian tube perfusion with ozone water in treating obstructed fallopian tube in pluripara.Methods A total of 116 patients with distal fallopian tube obstruction were included in this study.The diagnosis was confirmed by clinical and laboratory materials.The patients were randomly divided into the study group and the control group with 58 patients in each group.During hospitalization period all patients received interventional recanalization therapy for obstructed fallopian tube.For the patients of the study group,ozone water perfusion of fallopian tube was employed,while for the patients of the control group,fallopian tube perfusion with conventional anti-inflammatory drug and antiadhesion solution was adopted.All the patients were followed up for 6 months,the pregnancy rate and the fallopian tube re-occlusion rate of both groups were calculated,and 2 weeks after the treatment the patients'discomfort symptoms were evaluated.Results The success rate of fallopian tube recanalization,the pregnancy rate and the re-obstruction rate in the study group were 93.1％ (54/58),79.3％ (46/58) and 5.2％(3/58) respectively,which in the control group were 91.4％ (53/58),60.3％ (35/58) and 172％ (10/58) respectively.Statistical analysis indicated that no significant difference in the success rate of fallopian tube recanalization existed between the two groups (P＞0.05).The pregnancy rate of the study group was higher than that of the control group,while the re-obstruction rate in the study group was lower than that in the control group;the differences between the two groups were statistically significant (P＜0.05).No significant differences in discomfort symptom scores existed between the two groups (P＞0.05).Conclusion Fallopian tube perfusion with ozone water can be adopted for tubal recanalization,this technique can effectively improve the postoperative pregnancy rate and reduce the tubal re-obstruction rate.

Primary liver cancer is one of the most common malignant tumors in the world, and hepatocellular carcinoma accounts for the majority of liver cancer. Hepatectomy is one of the most important treatment methods, but the high postoperative recurrence rate is the leading cause of treatment failure, which seriously reduces the long-term survival rate and reduces quality of life. Therefore, preventing the recurrence of liver cancer is an important part of treatment. At present, there is no standard program for the treatment of hepatocellular carcinoma to prevent recurrence after surgery, most of the treatment programs include transarterial chemoembolization, antiviral therapy, traditional Chinese medicine treatment, targeted therapy, immunity therapy, etc., which has certain clinical significance in preventing recurrence. This paper reviewed the research progress on preventing recurrence of hepatocellular carcinoma after surgery, which may provide guidance for the clinical study.

Purpose To investigate the diagnostic value of parameters derived from intravoxel incoherent motion (IVIM) model for benign and malignant breast lesions,and to provide reference for the identification of breast lesions.Materials and Methods 27 cases with 28 benign breast lesions and 34 cases with 35 malignant breast lesions were collected and analyzed retrospectively.All of the patients were examined with IVIM-DWI scans.GE AW 4.4 workstation was used to calculate the value of ADC,D,D* and f.The diagnostic performance of different parameters was evaluated by receiver operating characteristic curve (ROC curve).The ADC,D,D* and f value of malignant group and the benign group were compared,respectively.Results The value of ADC and D were significantly lower in malignant group than in benign group (P＜0.05),and the value of D* and fwere significantly higher in malignant group than in benign group (P＜0.05).The cutoff value of D was 0.74× 10-3 mm2/s,and the AUC were 0.907,the specificity,sensitivity in the diagnosis of malignant breast lesions was 0.86,0.95,respectively.Conclusions Parameters of IVIM-DWI are helpful in the differential diagnosis of benign and malignant breast lesions.

through incising portal vein;68 received postoperative transcatheter arterial chemoembolization (TACE).Thirty-six HCC patients with HVTT underwent tumor and HVTT resection;24 received postoperative TACE.Of 44 HCC patients with BDTT,23 underwent tumor and BDTT resection,21 underwent tumor resection + BDTT removal through incising common bile duct;29 received postoperative TACE.(3) Follow-up and survival:① 220 patients were followed up for 1-73 months,with a median time of 12 months.The median survival time,1-,3-and 5-year survival rates were respectively 12 months,48.2％,25.0％,15.4％ in 140 HCC patients with PVTT and 28 months,77.1％,45.6％,24.5％ in 36 HCC patients with HVTT and 36 months,88.6％,48.3％,24.6％ in 44 HCC patients with BDTT,with a statistically significant difference in survival (x2 =13.316,P＜0.05).② Of 140 HCC patients with PVTT,49 were in type Ⅰ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 20 months,60.3％,32.6％ and 17.1％;70 were in type Ⅱ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 13 months,51.4％,26.0％ and 17.3％;21 were in type Ⅲ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 7 months,9.5％,4.8％ and 0,showing a statistically significant difference in survival (x2=18.102,P＜0.05).The median survival time,1-,3-and 5-year survival rates were respectively 21 months,72.5％,42.5％,26.2％ in 51 patients undergoing tumor and TT resection and 9 months,40％,14.4％,0 in 89 patients undergoing tumor resection + PVTT removal through incising portal vein,showing a statistically significant difference in survival (x2=24.098,P＜0.05).③ Of 36 HCC patients with HVTT,17 were detected in right HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 14 months,64.7％,20.2％ and 0;10 were detected in left HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 53 months,80.0％,70.0％ and 38.9％;9 were detected in middle HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 40 months,88.9％,61.0％ and 30.5％;showing no statistically significant difference in survival (x2 =5.951,P＞0.05).④ Of 44 HCC patients with BDTT,24,6 and 14 were respectively detected in type Ⅰ,Ⅱ and Ⅲ BDTTs,and median survival time,1-,3-and 5-year survival rates were respectively 38 months,87.5％,60.4％,34.9％ in type Ⅰ BDTT patients and 26 months,83.3％,16.7％,0 in type Ⅱ BDTT patients and 35 months,78.6％,50.0％,21.4％ in type Ⅲ BDTT patients,showing no statistically significant difference in survival (x2 =5.312,P＞0.05).Of 44 patients,median survival time,1-,3-and 5-year survival rates were respectively 38 months,91.3％,59.5％,34.3％ in 23 patients undergoing tumor and TT resection and 26 months,85.7％,35.7％,15.3％ in 21 patients undergoing tumor resection + TT removal through incising common bile duct,showing no statistically significant difference in survival (x2 =2.071,P＞0.05).Conclusions HCC patients with PVTT have larger tumor diameter and worse liver dysfunction,and are prone to peritoneal effusion.HCC patients with different LVI undergo surgery.There is better prognosis in HCC patients with BDTT,and good prognosis in patients with HVTT,while poorer prognosis in patients with PVTT.The postoperative survival of HCC patients with PVTT is associated with TT type,and patients will have better prognosis after tumor resection + TT removal if TT type is confirmed earlier.The postoperative survival of HCC patients with BDTT is not associated with TT type,tumor resection + TT removal maybe prolong postoperative survival time.

Objective To study the clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) combined with agitation thrombolysis in treatment of acute portal vein thrombosis (PVT) in patients with liver cirrhosis.Methods The clinical data of 37 cirrhotic patients with acute PVT treated from January 2014 to December 2017 at the First Affiliated Hospital of Henan University of Science and Technology was analyzed.There were 20 males and 17 females with age ranging from 29 to 71 years.The patients were divided into the combined group (n =15) and the anticoagulation group (n =22).The combined group was treated with TIPS combined with agitation thrombolysis anticoagulation.The anticoagulation group was treated with anticoagulation.The changes in liver function and hemodynamics of portal vein of the two group were compared.Follow-up studies included postoperative portal vein patency,bleeding and survival rates of patients.Results The postoperative portal vein pressure and maximum burden of PVT in the combined group were significantly lower than those before operation,and the portal vein maximum blood volume and flow velocity of portal vein were significantly higher than those before operation (all P ＜ 0.05).At 2 weeks,6 months and 12 months after operation,the maximum burden of PVT of the combined group was (13.9 ±5.4)％,(16.1 ±5.5)％ and (13.8 ±6.2)％,respectively,which was significantly lower than that of the anticoagulant group (84.1±31.3)％,(85.9±27.6)％ and (88.2±39.5)％ (all P＜0.05).At 2 weeks,6 months and 12 months after operation,the flow velocity of portal vein of the combined group was (21.6 ± 5.7) cm/s,(16.1 ± 6.3) crn/s and (17.6 ± 4.9) cm/s,respectively,which was significantly higher than that of the anticoagulation group (9.7 ± 4.6) cm/s,(8.1 ± 4.3) cm/s and (8.2 ± 3.5) cm/s (all P ＜ 0.05).After operation,3 patients in the combined group developed recurrence of portal vein thrombosis,while the remaining patients had smooth blood flow in the portal vein and shunt.In the anticoagulation group,only 3 patients had unobstructed portal vein blood flow.The cumulative rate of no gastrointes tinal bleeding in the combined group was significantly better than the anticoagulant group.The cumulative survival rate of the combined group was also significantly better than the anticoagulation group (P ＜ 0.05).Conclusion TIPS combined with agitation thrombolysis was more effective than the traditional anticoagulant therapy in treatment of acute portal vein thrombosis in cirrhotic patients.

Objective: To study the clinical application of three-dimensional (3D) visualization technology in liver resection of complicated liver cancer. Methods: A retrospective analysis of 28 patients with complicated liver cancer treated from June 2017 to June 2018 in the Department of Hepatobiliary Surgery, the Affiliated Tumor Hospital of Guangxi Medical University. There were 26 males and 2 females, aged (46±10) years old. A treatment plan on how to perform liver resection for these patients was developed under the guidance of 3D visualization technology. The actual surgical procedures, operation time, intraoperative blood loss, and postoperative complications were documented. The virtual resected liver volume was compared with the actual resected liver volume. The virtual surgical resection margin was also compared with the actual surgical resection margin. Results: All the 28 patients with complicated liver cancer completed the 3D visualization analysis with the location, shape and quantity of tumor being clearly shown. Of the 27 patients who underwent liver resection, 13 underwent anatomical hepatectomy, and 14 underwent non-anatomical hepatectomy. The operation time ranged from 145 to 350 min (median 240 min). The intraoperative blood loss ranged from 100 to 1 500 ml (median 300 ml). The incisional wound healed slowly in 4 patients, pleural effusion developed in 8 patients, and ascites in 2 patients. There were no significant differences in the virtual resected liver volume compared with the actual resected liver volume (P>0.05). There was an excellent positive correlation between the patient's virtual resected liver volume and the actual resected liver volume (r=0.986, P<0.05). There was no significant difference between the virtual surgical resection margin and the actual surgical resection margin (P>0.05). There was an excellent positive correlation between virtual surgical resection margin and the actual surgical resection margin (r=0.983, P<0.05). Conclusion Three-dimensional visualization technology accurately assessed the liver status, optimized surgical procedures, and played an important role in liver resection of complex liver cancer.

Objective The objective of this study was to investigate the effect of depression on serum levels of C-reactive protein(CRP)and high-sensitivity C-reactive protein(hs-CRP),and prognosis in liver cancer patients. Methods A total of 251 patients with liver cancer undergoing hepatectomy were enrolled. The hospital anxiety and depression scale( HADS-D) and 9-item patients health questionnaire(PHQ9) were assessed for depression before 3 days for surgery. Patients were divided into depression group(n=95)and non-depression group(n=156) according to the scores. Preoperative serum levels of CRP,hs-CRP,ALT and AST were measured and compared between the depression and non-depression groups. Survival analysis Kaplan-Meier method was used to compare the disease-free survival(DFS)and total survival(OS)between the two groups. Results The serum levels of CRP, hs-CRP,ALT and AST in the depression group were significantly higher than those in the non-depression group(P<0. 05). The follow-up of 3. 5-year showed that 164 patients(65 in depression group and 99 in non-depression group)had recurrence or metas-tasis and 47 patients(22 in depression group and 25 in non-depression group) died. The DFS and OS in the depression group were significantly lower than those in the non-depression group(P< 0. 05). Cox multiple regression analysis showed that liver function grading,BCLC staging and depression were independent risk factors for the prognosis of liver cancer. Spearman correlation analysis showed that patients′degree of depression was positively correlated with serum levels of CRP and hs-CRP(P<0. 05),DFS and OS were negatively correlated with serum levels of CRP and hs-CRP(P<0. 05). Conclusion Depression may mediate elevated serum levels of CRP and hs-CRP,maintain inflammatory response in patients,lead to increased liver function damage,elevate levels of ALT and AST,and thus adversely affect the prognosis of patients with liver cancer.

Objective:To explore the clinicopathological characteristics and prognosis of pancreatic gastrointestinal interstitial tumors(pGISTs).Methods:Three cases of pGISTs diagnosed in the Affiliated Tumor Hospital of Guangxi Medical University from August 2015 to October 2019 were analyzed retrospectively. Relevant literatures at home and abroad were searched and reviewed through PubMed, China knowledge Network, Wanfang and VIP databases. The sex, age, tumor size, tumor location, cystic or solid tumor, mode of treatment, mitosis, gene mutation, survival status and survival time were recorded, and the correlation between tumor cystic-solid characteristics and clinicopathological parameters was analyzed. Kaplan-Meier′s method was used to calculate the overall survival (OS) rate and disease-free survival (DFS) rate. Univariate and multivariate Cox regression models were used to analyze the independent risk factors affecting the prognosis of pGISTs.Results:In this group, 3 cases were combined with 71 cases reported in the literature, and a total of 74 cases of pGISTs were included. Among them, 36 cases were male and 38 were female, the age of onset was 55(19-84) years, and the diameter of the tumor was 8 cm(2-35 cm). The tumor location of 71 patients was recorded by literature; 30 cases (42.3%) were located in the head of the pancreas. The solid-cystic characteristics of tumor in 63 patients were recorded by literature, and 33 cases (52.4%) were solid. The mode of treatment of 74 patients was recorded, and 60 cases (81.1%) underwent radical resection. The mitosis figures of 59 patients were recorded, and 33 cases (55.9%) were <5/50 high power field of vision (HPF). The gene mutation of 14 patients was recorded, and 11 cases (78.6%) were c-kit exon gene mutation. Correlation analysis showed that the cystic-solid characteristics of the tumor were significantly correlated with tumor location, tumor diameter and mitosis figures, but not with age, sex, histological type, Ki-67 index and modification National Institutes of Health(mNIH) classification. The 5-year OS rate of 51 patients after radical resection was 88.8%, and the 5-year DFS rate was 60.3%. The 1-year OS rate of patients receiving palliative treatment was 51.9%, and the 1-year fatality rate was 33.3%. Univariate Cox regression analysis showed that male ( P=0.083), mitosis figures >5/50 HPF ( P=0.008)and CD 34 negative ( P=0.055)were risk factors for postoperative recurrence of pGISTs, while multivariate Cox regression analysis showed that mitosis figures >5/50 HPF ( P=0.023)was an independent risk factor for the prognosis of pGISTs. Kaplan-Meier survival analysis showed that patients with mitosis figures ≤5/50 HPF had a higher survival rate ( P=0.0003), but there was no significant difference on prognosis between patients with 10/50 HPF and >10/50 HPF( P=0.3075). Conclusions:pGISTs usually occured in the head of pancreas, and the tumor volume was usually found to be large. The main treatment was radical operation, and the main mutation type was exon mutation of c-kit gene. Nuclear fission image figures >5/50HPF was an independent risk factor for postoperative recurrence.

Objective:To analyze the impact of gender on prognosis in patients with primary hepatocellular carcinoma (HCC) after hepatectomy.Methods:The data of 1 796 patients with HCC who underwent liver resection at the Guangxi Medical University Cancer Hospital from January 2010 to December 2016 were retrospectively analyzed. There were 1 548 males and 248 females, the average age were 49.6 years. Patients were followed up for recurrence and survival. After propensity score matching, the postoperative survival rates of male and female patients were compared. Univariate and multivariate Cox regression was used to analyze independent factors affecting prognosis of patients with HCC after hepatectomy. The age and menopause were analyzed by subgroup analyses.Results:The 1-, 3- and 5-years cumulative overall and recurrence-free survival rates of male patients were significantly lower than that of female patients (all P<0.05). Multivariate analysis showed that female was an independent protective factor affecting postoperative recurrence ( HR=0.777, 95% CI: 0.615-0.982) and overall survival ( HR=0.669, 95% CI: 0.520-0.856). Using a cut-off value of 50 years old, the patients were divided into <50 years old ( n=915) and ≥50 years old ( n=881). In patients who were less than 50 years old, the 1-, 3- and 5-years cumulative overall and recurrence-free survival rates of male patients were significantly lower than those of female patients (all P<0.05). In patients ≥50 years old, there were no significant difference in the cumulative overall and recurrence-free survival rates between male and female patients (all P>0.05). Female patients were then divided into the postmenopausal group ( n=152) and the premenopausal group ( n=96). There were no significant differences in the cumulative overall and cumulative recurrence-free survival rates between the two groups ( P>0.05). Conclusion:The prognosis of female patients with HCC after hepatectomy was significantly better than that of male patients.
