Objective To evaluate the regulatory effect of Diwu Yanggan(DWYG)Decoction on lysoglycerophospholipids(Lyso-GPLs)in circulating exosomes in a mouse model of nonalcoholic fatty liver disease(NAFLD).Methods Circulating exosomes isolated from mouse serum by size exclusion chromatography were morphologically characterized using transmission electron microscope and examined for surface markers CD9,CD63 and TSG101 using Western blotting.Twenty-four male Kunming mice were randomized into 3 groups for normal feeding(control,n=8)or high-fat diet feeding for 1 week to induce NAFLD,after which the latter mice were given DWYG decoction(treatment group,n=8)or normal saline(model group,n=8)by gavage for 4 weeks.After the last treatment,blood samples were collected from the mice for testing serum TC,HDL-C,LDL-C,ALT and AST levels and isolating circulating exosomes.Using multivariate statistical analysis based on targeted metabolomics strategy,the potential biomarkers for Lyso-GPLs in the exosomes were screened.Results The isolated exosomes about 100 nm in size had a typical saucer-like structure with distinct double-layer membranes and a mean particle size of 137.5 nm and expressed the specific surface marker proteins CD9,CD63 and TSG101.The mouse models of NAFLD had significantly increased serum levels of TC,HDL-C,LDL-C and AST and lowered serum ALT level.A total of 43 Lyso-GPLs with significant reduction after DWYG Decoction treatment were identified in NAFLD mice.Conclusion DWYG Decoction can regulate Lyso-GPLs in circulating exosomes in NAFLD mice,which provides a new clue for studying the therapeutic mechanism of DWYG Decoction for liver disease.

Objective:To assess the impact of preoperative Naples prognostic score on the prognosis of patients with hepatocellular carcinoma (HCC) after hepatic resection.Methods:Retrospective analysis was conducted on the data of 323 patients with HCC who underwent radical hepatectomy in Zhejiang Provincial People's Hospital from January 2012 to December 2017, including 281 males and 42 females, aged (56.6±11.3) years. All patients were divided into three groups according to their preoperative Naples prognostic scores: group A (0) ( n=37), group B (1-2) ( n=193), group C (3-4) ( n=93). Survival was analysed by the Kaplan-Meier method, and differences in survival were compared by the log-rank test. Univariate and multivariate Cox regression were used to analyse the effect of Naples prognostic score on prognosis. Results:The 1-, 3- and 5-year cumulative survival rates of HCC patients after hepatectomy were 91.9%, 78.4% and 68.3% in the A group, 89.1%, 76.1% and 64.4% in the B group, and 84.9%, 63.3% and 43.5% in the C group, respectively, and the cumulative survival rates showed a decreasing trend among the three groups, and the differences were statistically significant (all P<0.05). The recurrence-free survival rates at 1, 3 and 5 years after hepatectomy were 93.4%, 63.3% and 44.3% in the A group, 77.7%, 46.5% and 35.6% in the B group, and 64.1%, 41.1% and 28.2% in the C group, respectively, and the recurrence-free survival rates showed a decreasing trend among the three groups, and the differences were statistically significant (all P<0.05). On Cox multivariate analysis, patients with HCC of 3-4 had a higher risk of death after hepatic resection than those patients of 0 ( HR=2.011, 95% CI: 1.048-3.859, P=0.036), and the risk of postoperative recurrence was also higher than those patients of 0 ( HR=1.820, 95% CI: 1.081-3.066, P=0.024). Conclusion:Preoperative Naples prognostic score performs as a prognostic influence factor on survival and recurrence-free survival after hepatectomy in patients with HCC.

Primary hepatic carcinoma has ranked as the sixth most commonly diagnosed cancer and the third leading cause of cancer death. China shares about 50% of new liver cancer cases, including 80% of hepatic carcinoma. Non-surgical therapy continues to make breakthroughs. The authors report a case of hepatic carcinoma with intrahepatic metastasis and tumor thrombus in the left portal vein, which has achieved continious partial response after the treatment of atezoli-zumab combined with bevacizumab, without adverse reactions such as liver and kidney function damage. The life quality of the patient was improved, showing safety and efficacy of the treatment.

Objective:To study the technical and essential steps in laparoscopic selective devascularization with paraesophageal veins-preservation.Methods:To retrospectively analyze the clinical data of 13 cirrhotic patients who underwent laparoscopic selective pericardial devascularization for portal hypertension at the Department of Hepatobiliary and Pancreatic Surgery, Zhejiang Provincial People's Hospital from January 2019 to March 2020. There were 9 males and 4 females with age ranging from 41 to 83 years (median 51 years). The operative time, intraoperative blood loss, postoperative complications and follow-up data were analyzed.Results:All the 13 patients completed theoperation, no patient stopped the operation or transferred to laparotomy. The operation time was (170±32) min.The intraoperative bleeding was (160±30) ml. The postoperative hospital stay was (6.1±1.1) days. There were no complications, including pancreatic leakage and intra-abdominal infection. On follow-up which ranged from 1 to 15 months, one patient developed portal vein thrombosis, no upper gastrointestinal rebleeding.Conclusions:Preservation of esophageal veins in laparoscopic selective devascularization is an accurate surgery which requires close teamwork and rich experience in laparoscopic surgery. The preservation of the main trunk of the gastric coronary vein and integrity of the esophageal veins are the keys to the surgery which is safe and feasible.

Objective:To evaluate the effects of fluorinated porcine hydroxyapatite (FPHA) on guided bone regeneration of peri-implant buccal bone defects in canine mandible.Methods:Six male beagle dogs were randomly divided into two groups with different time points (4 weeks and 12 weeks after implants placement), with 3 dogs in each group. Bilateral mandibular second premolars, first molars, and second molars in each dog were extracted. The wounds were allowed to heal for 12 weeks. For each dog, four implant beds were prepared in each side and standardized peri-implant buccal bone defect was created at each implant site. After implants placement, the defect sites were randomly allocated in a split-mouth design to blank control group, deproteinized bovine bone mineral (DBBM), the porcine hydroxyapatite (PHA), FPHA and covered with collagen membranes. The animals were sacrificed 4 or 12 weeks after the surgery. Biopsies of the implant sites were obtained for micro-CT evaluation [bone volume fraction (BV/TV) and bone trabecular separation degree (Tb.Sp)] and histological analysis.Results:Micro-CT results showed that 4 weeks after implants placement, PHA, FPHA and DBBM successfully maintained the contour of alveolar ridge at the buccal aspect of the implants, while the contour of alveolar ridge collapsed in the blank control group. BV/TV in the FPHA group [(24.77±2.20) %] was significantly higher than that in the PHA group [(16.89±1.70)%] and DBBM group [(15.68±3.15)%] ( P<0.05). Tb.Sp in the FPHA group (0.70±0.07) was significantly lower than that in the DBBM group (1.03±0.19) ( P<0.05). Twelve weeks after implants placement, the alveolar ridge contour of the grafted sites in PHA, FPHA and DBBM group remained stable. The alveolar ridge of the blank control group was still collapsed. There was no significant difference in BV/TV and Tb.Sp between PHA group, FPHA group and DBBM group. The histomorphological analysis showed that 4 weeks after implants placement, in the central area of the defect, the amount and maturity of new bone (NB) around the material particles in FPHA group was higher than that in PHA group and DBBM group. Osseointegration could be observed between the NB and implant surface in all the four groups. Twelve weeks after implants placement, the material particles were surrounded by a large number of mature NB in PHA, FPHA and DBBM group. Conclusions:The incorporation of fluoride ion into PHA could effectively promote the repair of peri-implant bone defects in the early stage of guided bone regeneration.
