Objective To compare the efficacies of intralesional hyaluronidase(HAase), intralesional dexamethasone(DEX), and intralesional HAase plus intralesional DEX on skin damage caused by vinorelbine extravasation in a rat model. Methods After establishing an animal model with vinorelbine extravasation in each lower extremity of 40 Sprague-Dawley rats, we treated the rats with intralesional HAase,intralesional DEX, intralesional HAase plus intralesional DEX,intralesional saline,or received no treatment as control.The wound area on 1 d, 4 d, 8 d, 12 d, 18 d, 24 d, 30 d and the time of healing were observed and compared.Results The wound area on 1 d, 4 d, 8 d, 12 d, 18 d and 24 d was significantly lower in intralesional HAase group, intralesional DEX group,intralesional HAase plus intralesional DEX group,and intralesional saline group than that in control group (P <0.05), and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P <0.05). The healing time was significantly shorter in 4 therapy groups than that in control group [(25.1±3.1) d, (27.9±2.8) d, (23.0±3.2) d, and (28.4±3.9) d vs.(31.2±3.0) d, P <0.05], and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P <0.05). Conclusion The monotherapy with intralesional HAase or intralesional DEX, with decreasing the extent of skin damage and shortening the healing time, is effective therapy for skin damage caused by vinorelbine extravasation, and the monotherapy with intralesional Haase is more efficacious. The efficacy of intralesional HAase plus intralesional DEX seems better than that of monotherapy.

Objective To investigate the expression of bone sialoprotein (BSP) in prostate cancer and its clinical significance. Methods Prostate cancer tissues of different pathological grades (68 cases) and benign prostatic hyperplasia tissues (22 cases) were selected. SP method was used to detect the expression of BSP. Serum total prostate-specific antigen (tPSA) levels of prostate cancer were detected by electrochemiluminescence immunoassay before the operation. Results Compared with no or low expression in the adjacent normal glandular tissues, the detectable levels of BSP were examined in most of the prostate cancer tissues. The expression rate of BSP in prostate cancer tissues was higher than that in benign prostatic hyperplasia tissues [76.47%(52/68) vs 13.64%(3/22),χ2=27.614, P<0.001]. The expression rates of BSP in well differentiated, moderately differentiated and poorly differentiated tissues according to cell differentiating degree (Gleason system) were 75.0 % (12/16), 77.5 % (31/40) and 75.0 % (9/12) respectively. There was no significant difference in various pathological grading (χ2=0.057, P=0.972). The expression rates of BSP in pathological stage pT2, pT3 and pT4 tissues were 62.16%(23/37), 95.24%(20/21) and 90.0%(9/10) respectively. A statistically significant association was found between BSP expression and pathological stage (χ2=9.338, P=0.009). Serum tPSA level of prostate cancer group with BSP expression was higher than that with no BSP expression [(69.06±25.52)μg/L vs (38.00±21.64)μg/L, F=19.355, P<0.001]. Conclusion The high expression of BSP in prostate cancer has a relationship with pathological stage and serum tPSA level, it may play an important role in the biological behaviour of prostate cancer.

Objective To analyze the efficacy and safety of CyberKnife combined with temozolomide (TMZ) in treatment of brain metastasis of non-small cell lung cancer (NSCLC). Methods From March 2013 to March 2016, 62 NSCLC patients with brain metastases in department of oncology of the 187th Hospital of PLA were divided into two groups according to the random number table method, the CyberKnife combined with TMZ group (CyberKnife + TMZ group, 31 cases) and simple CyberKnife group (CyberKnife group, 31 cases). Hypofractionated radiation of CyberKnife was given 18-36 Gy in 1-5 fractions of 5-25 Gy. CyberKnife+ TMZ group was given temozolomide 150 mg·m-2·d-1 for 5 days in first cycle, then every 28 days they received temozolomide therapy from the second to the sixth cycles: 200 mg·m-2·d-1 for 5 days. The clinical symptom remission rate after the treatment of CyberKnife in one week, the effective rate after CyberKnife in 3 months, the median intracranial progression-free survival time, overall survival, and the incidences of adverse reaction were comparatively analyzed. Results The clinical symptom remission rates of CyberKnife+TMZ group and CyberKnife group after the treatment of CyberKnife in one week were 93.6 % (29/31) and 96.8 % (30/31). There was no significant difference in the clinical symptom remission rates (χ2= 1.207, P=0.547). The effective rates of the two groups after CyberKnife in 3 months were 93.6 % (29/31) and 90.3 %(28/31). There was no significant difference in the effective rates (χ2 = 0.695, P= 0.706). The median intracranial progression-free survival time in CyberKnife + TMZ group (14.0 months) was significantly higher than that in the CyberKnife group (9 months) (χ2=8.977, P=0.003), and the median overall survival time in CyberKnife + TMZ group (15.0 months) was also significantly higher than that in the CyberKnife group (12.0 months) (χ2 = 5.190, P= 0.023). There was no significant difference in the adverse reaction of the central nervous system between the two groups (χ2=0.746, P=0.689), but the adverse reactions of the digestive system (χ2 = 6.062, P= 0.014) and the hematologic system (χ2 = 6.613, P= 0.010) in CyberKnife + TMZ group were significantly higher than those in the CyberKnife group. Systemic adverse reactions of the two groups were tolerated by most patients. Conclusions CyberKnife combined with TMZ is a feasible therapeutic option for NSCLC patients with brain metastases. This therapy can improve the median survival time to cerebral progression of the disease and the median overall survival time.

Objective:To explore the characteristics of T lymphocyte subsets and cytokines in hyperlipidemia-induced acute pancreatitis (HLAP) and its prognostic value.Methods:This study included 184 patients with acute pancreatitis (AP) admitted to the First Affiliated Hospital of Xiamen University from January 2018 to May 2021. Based on disease etiology, there were 92 HLAP cases and 92 non-hyperlipidemia-induced AP (NHLAP) cases. Stratified by disease severity according to 2012 Atlanta classification criteria, the patients were divided into the severe subgroup (SAP) and non-severe subgroup (NSAP). Peripheral venous blood samples were taken from all patients on day 1, 3, and 5 after admission. T lymphocyte subsets were determined by flow cytometry, and cytokines were detected by flow fluorometry. The number of CD4 +% and CD8 +% and the expression of cytokines were compared by Student’s t test or Mann-Whitney U analysis. Logistic regression analyses were performed to identify risk factors for severe AP, and a receiver operating characteristic (ROC) curve was constructed to predict severe AP. Statistical significance was taken as P<0.05. Results:Compared with the NHLAP group, patients in the HLAP group had lower CD4 +%, while higher levels of IL-2 on day 1 ( P<0.05), and had also lower CD4 +%, while higher levels of IL-4, IL-6, and IL-10 on day 3 ( P<0.05). Furthermore, IL-6 and IL-10 levels of the HLAP group were significantly increased compared to the NHLAP group on day 5 ( P<0.05). IL-10 levels in the SAP subgroup were significantly higher than those in the NSAP subgroup on day 1 ( P<0.05). Compared with the NSAP subgroup, the SAP subgroup had elevated levels of IL-2, IL-4, IL-6, IL-10 and IFN-γ on day 3 (all P<0.05), and had lower CD4 +%, while increased levels of IL-6 and IL-10 on day 5 (all P<0.05). Multivariate Logistic regression analysis showed that IL-10 was an immune indicator of independent risk factor for severe AP in the HLAP group on day 1 ( OR=1.139, 95% CI: 1.038-1.251, P<0.05). Finally, ROC analysis showed that the area under the curve of IL-10 to assess HLAP with severe AP was 0.772, and the best cut-off value for predicting severe AP was 5.6 pg/mL, with a sensitivity of 83.3% and a specificity of 68.8%. Conclusions:Changes of CD4 +% and cytokines are different between the HLAP and NHLAP groups. IL-10 can be used as a predictor of early disease severity in patients with HLAP.

Objective:To compare the perioperative outcomes between robotic pancreaticoduodenectomy(RPD)and laparoscopic pancreaticoduode-nectomy(LPD)in patients aged ≥65 years. Methods:The clinical data of 130 patients aged ≥65 years who received minimally invasive pancreaticoduodenectomy(MIPD)at Department of Gastrointestinal and Pancreatic Surgery,Zhejiang Provincial People's Hospital from January 2019 to December 2022 were retrospectively analyzed.The patients were divided into the RPD group(n=66)and the LPD group(n=64)according to the operation method,and the perioperative clinical data were compared between the 2 groups. Results:Compared with the LPD group,the average age of patients in the RPD group was higher than that of the LPD group[(71.95±4.73)years vs(70.39±3.9)years,P<0.05];the RPD group had more patients with diabetes(39.4%vs 18.8%,P<0.05)and cardiopulmonary diseases(37.9%vs 17.2%,P<0.05);the RPD group had shorter operation time[(272.91± 68.38)min vs(362.81±78.24)min,P<0.05]and less intraoperative blood loss[median(range):1 00 mL(50-200 mL)vs 1 50 mL(1 00-200 mL),P<0.05)];the RPD group had higher incidence of chylous fistula(1 2.1%vs 1.6%,P<0.05)but lower incidence of surgical morbidity(37.9%vs 46.9%),serious complications(19.7%vs 34.4%),postoperative pancreatic fistula(12.1%vs 17.2%),biliary fistula(3.0%vs 3.1%),abdominal infection(10.6%vs 14.1%),postoperative bleeding(4.5%vs 4.5%),and postoperative cardiopulmonary complications(1 2.1%vs 20.3%)with no statistically significant difference(P>0.05);the RPD group waited shorter time before restarting diet[(3.97±1.59)d vs(5.34±2.56)d,P<0.05]. Conclusion:MIPD is safe and feasible in patients aged ≥65 years.The incidence of perioperative complications is similar between the 2 groups.Compared with LPD,RPD has shorter operation time,less intraoperative blood loss,and shorter duration before restarting diet after operation,which has certain clinical advantages.
