Objective:To explore the mechanism of the active compounds in Banxia Houpo Decoction treating tension type headache through network pharmacology and molecular docking.Methods:The potentially effective components and targets of Banxia Houpo Decoction were screened by TCMSP, and the action targets of tension type headache were obtained by GeneCards, PharmGKB, TTD, Drugbank and OMIM. The intersection target of "Banxia Houpo Decoction - tension type headache" was obtained by Perl software. The protein interaction network was uploaded to STRING database and topological analysis was carried out. With the help of Cytoscape 3.8.0 software, the visualization network of "Banxia Houpo Decoction - medicine ingredient-Target-tension type headache" was constructed, and the GO enrichment analysis and KEGG pathway enrichment analysis of the intersection targets were carried out by using R 4.1.0 language and related programs. The AutoDockTools-1.5.6 software was used to complete the molecular docking analysis.Results:There were 33 intersection targets in Banxia Houpo Decoction and tension type headache. Topological attribute analysis suggested that MAPK1, TP53, ESR1, PTGS2, MYC, CYP1A2, CYP3A4 and GSTP1 might be important potential targets of Banxia Houpo Decoction in the prevention and treatment of tension type headache. GO enrichment analysis showed 516 cell biological processes (BP), 62 cell components (CC) and 149 molecular functions (MF). KEGG pathway enrichment analysis showed that there were 94 related signal pathways, such as cGMP-PKG signaling pathway, Cholinergicsynapse, Serotonergic synapse and TNF signaling pathway.Conclusions:Banxia Houpo Decoction has multi-component, multi-target and multi-pathway characteristics in the prevention and treatment of tension-type headache. It mainly acts on 5-HT synaptic pathway, TNF signal pathway, cholinergic synaptic pathway, G protein coupled receptor pathway and other pathways through ESR1, TP53, PGTS2 and other multi target.

Objective To explore the clinical value of uncinate process resection combined with portalsuperior mesenteric vein resection and end-to-end anastomosis in distal pancreatectomy.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 11 patients who underwent distal pancreatectomy combined with portal-superior mesenteric vein resection and end-to-end anastomosis in the Peking University Cancer Hospital (8 patients) and Jilin Guowen Hospital (3 patients) between January 2014 to April 2018 were collected.During the vascular reconstruction,uncinate process of the pancreas was first resected for reducing anastomotic tension,and then end-to-end anastomosis was done after portal-superior mesenteric vein resection.Observation indicators:(1) intraoperative situations;(2) postoperative recovery situations;(3) postoperative pathological examination situations;(4) follow-up and survival situations.Follow-up using outpatient examination and imaging examination was performed to detect patients' postoperative survival,tumor recurrence and metastasis and postoperative venous anastomotic patency up to May 2018.Measurement data with normal distribution were represented as x±s.Measurement data with skewed distribution were described as M (range).The non-recurrence and non-metastasis survival curve,overall survival curve and survival rate were respectively drawn and calculated by the Kaplan-Meier method.Results (1) Intraoperative situations:11 patients received uncinate process resection of the pancreas,and successfully underwent distal pancreatectomy combined with portal-superior mesenteric vein resection and end-to-end anastomosis.Eight patients underwent distal pancreatectomy + Appleby combined with celiac axis resection due to pancreatic tumor involving common hepatic artery,including 2 undergoing combined total gastrectomy due to gastric ischemia;2 patients underwent distal pancreatectomy;1 patient underwent distal pancreatectomy + distal gastrectomy due to blood supply obstacle of distal stomach.Operation time and volume of intraoperative blood loss of 11 patients were (5.8± 1.1) hours and 800 mL (range,200-2 500 mL).(2) Postoperative recovery situations:there was no grade C of pancreatic fistula of 11 patients.Four patients had grade B of pancreatic fistula,including 2 were cured by drainage-tube indwelling of pancreatic wound ＞ 3 weeks,1 was cured by continous washing due to pancreatic fistula combined with infection,and 1 was cured by the second abdominal puncture drainage due to pancreatic fistula with fever;1 of 4 patients was combined with grade C of delayed gastric emptying and cured by conservative treatment,and other 3 patients didn't occur postoperative complications.Of 5 patients diagnosed as biochemical fistula,1 had esophagus-jejunum anastomotic leakage,and 1 had changes of hepatic ischemia in S2,S3 and S4b segments by CT examination and recovered normal liver function at 2 weeks postoperatively,with long-term hepatatrophia in S2 and S3 segments.There was no postoperative death and reoperation in 11 patients.Duration of postoperative hospital stay of 11 patients was (22± 5) days.(3) Postoperative pathological examination results:tumors of 11 patients were located in neck and body of the pancreas,with a maximum diameter of (4.8± 1.7)cm.Among 11 patients,10 were confirmed with moderate-or low-differentiated ductal adenocarcinoma and 1 with anaplastic carcinoma.The length of portal-superior mesenteric vein resection of 11 patients was (2.6± 0.8) cm.Seven of 11 patients occurred different degrees of tumor infiltration in the portal-superior mesenteric vein,and other 4 patients occurred inflammatory adhesion,without tumor infiltration.(4) Follow-up and survival situations:11 patients were followed up for 3.0-37.6 months,with a median time of 15.7 months.During the follow-up,8 patients died of tumor recurrence and /or metastasis,and 3 survived;the non-recurrence and non-metastais survival time and overall survival time were respectively 9.0 months (range,3.0-37.6 months) and 24.6 months (range,3.0-37.6 months).One patient was complicated with anastomotic stenosis and surrounding varices of portal-superior mesenteric vein by postoperative half-year reexamination,anastomotic vein anomalies and venous thrombosis were not found in other patients before local tumor recurrence and / or death.Conclusion The combined uncinate process resection of the pancreas cannot increase the risk of postoperative pancreatic fistula,and it could effectively reduce the anastomotic tension in the distal pancreatectomy combined with portal-superior mesenteric vein resection and reconstruction,meanwhile,it can also achieve end-to-end anastomosis after longer vein resection.

Objective:To investigate the feasibility and safety of right-sided abdominal evisceration in retroperitoneal liposarcoma.Methods:The clinical data of 16 cases of retroperitoneal liposarcoma performed with right-sided abdominal evisceration at Sarcoma Center of Peking University Cancer Hospital from Sep 2015 to Feb 2019 were analyzed retrospectively.Results:Complete resection were successfully performed in all 16 cases.The median tumor size was 29cm(13-43 cm), the median operative time was 660 min(429-940 min), the median estimated blood loss was 2 000 ml(300-6 000 ml). The major postoperative complications rate (Clavien-Dindo classification Ⅲ-Ⅴ) was 38%. Median overall survival is 41.0 months while the median disease-free survival is 32.6 months.Conclusions:Right-sided abdominal evisceration is a favorable procedure to attain complete resection with acceptable complication rate.

BACKGROUNDThe management of Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) is controversial due to the early recurrence after curative hepatectomy, and many variables were related to the prognosis. The purpose of this study was to predict the tumor recurrence in early postoperative period of the patients with BCLC stage B HCC.

METHODSFrom January 2004 to January 2012, 104 patients with BCLC stage B HCC underwent hepatectomy. Clinicopathological factors and follow-up data were statistically analyzed to establish a predicting scoring system.

RESULTSThe overall survival rates for one, three, and five years were 69.2%, 52.7%, and 42.3%, and the disease-free survival rates for one, three, and five years were 52.9%, 47.3%, and 37.5%, respectively. The multiple factors analysis showed that the micro-vessel invasion, lymph nodes metastasis, multiple lesions, and the high expression of HMGB1 were independent factors (P < 0.05). A scoring system was established to predict the early recurrence within one year after the surgery for BCLC stage B HCC, according to the analysis results with a specificity of 85.1% and a sensitivity of 80.3%.

CONCLUSIONVariant clinicopathological factors were associated with early postoperative recurrence for BCLC stage B HCC and recurrence early after hepatectomy was more likely in patients with a higher score of the scoring system.
