Objective:To investigate the clinical efficacy of extended hepatectomy for hilar cholangiocarcinoma (HCCA) of Bismuth-Cor-lette typesⅢandⅣ(the longitudinal invasion degree along the biliary system is the main criteria). Methods:The clinical data of 61 patients with HCCA of Bismuth-Corlette types III and IV admitted in the Department of Hepatobiliary Surgery of the First Affiliated Hos-pital of Bengbu Medical College from January 2008 to May 2015 were analyzed retrospectively. Among the 61 cases, 22 underwent hepatectomy with half or over half of the liver removed or hepatic caudate lobectomy (regarded as the extended hepatectomy group), whereas 39 cases underwent irregular hepatectomy on the hepatic hilar region (regarded as the limited hepatectomy group). Results:Compared with those in the limited hepatectomy group, the patients in the extended hepatectomy group underwent longer duration of operation and experienced more bleeding during the procedure. The complication incidence rate for the extended hepatectomy group was lower than that for the limited hepatectomy group. No patient died during the perioperative period in the extended hepa-tectomy group, whereas two patients died in the limited hepatectomy group. Moreover, R0 resection was performed on 21 cases in the extended hepatectomy group, with a resection rate of (21/22) 95.5%, and on 20 cases in the limited hepatectomy group (P<0.05), with a resection rate of (20/39) 51.3%. Actuarial 1-, 3-, and 5-year survival rates were 77.27%, 36.36%, and 13.64%, respectively, in the extended hepatectomy group, and 69.23%, 20.51%, and 1.64%, respectively, in the limited hepatectomy group (P<0.05). Conclusion:Extended hepatectomy for patients with HCCA of Bismuth-Corlette typesⅢandⅣcould effectively increase the resection rates of R0 and the survival rate. Meanwhile, the prognosis of patients could be improved.

This article aims to comprehensively review the concept, etiology, classification, classical cortical mapping, assessment, a proposed flowchart for the diagnosis and differential diagnosis, treatment, rehabilitation, mechanisms of development and recovery, prognosis, and influencing factors for post-stroke aphasia(PSA)types in the Chinese language.We emphasize the necessity and significance of neuroimaging assessment of the brain and blood vessels and neuropsychological assessment in the diagnosis and differential diagnosis of PSA in Chinese.We also recommend and encourage the use of the dichotomies of internal vs.external and anterior vs.posterior as a starting point, based on the association of anatomical locations of the brain and blood vessels with brain language areas and language disorders.A classification system of PSA in Chinese developed from this approach in the form of a flowchart is well-suited for guiding the clinical treatment of cerebral stroke.Incorporating the "four elements" , the flowchart enables convenient diagnosis, classification and differential diagnosis of PSA in Chinese and facilitates targeted and personalized rehabilitation planning to benefit the patient.This article introduces the use of memantine, piracetam, donepezil and other drugs for PSA treatment, evaluates clinical trials on memantine conducted in China and abroad and its mechanisms of action for the treatment of PSA, and discusses how rehabilitation therapy achieves therapeutic effects.For the treatment of PSA, clinical research and practice using drugs such as memantine, piracetam and donepezil in combination with non-pharmacotherapy and rehabilitation training should be promoted.

Objective:
To investigate the effects of preoperative percutaneous transhepatic biliary drainage on surgical treatment of type Ⅲ and Ⅳ hilar cholangiocarcinoma.
Methods:
Clinical data of 72 patients with hilar cholangiocarcinoma of the Bismuth-Corlette type Ⅲ and Ⅳ treated at Department of General Surgery,First Affiliated Hospital of Bengbu Medical College from January 2010 to December 2017 were analyzed retrospectively.Patients were divided into two groups based on whether PTBD was performed:a drained group and an undrained group.In the drained group,there were 31 patients,20 males and 11 females,aged (59.9±9.7)years (range: 39-73 years).Among them,14 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 17 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).In the undrained group,there were 41 patients, 26 males and 15 females, aged (60.8±7.8)years(range: 45-75 years).Among them, 17 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 24 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).Percutaneous transhepatic biliary drainage(PTBD)was used in the drained group.Under the guidance of ultrasound,one or more hepatobiliary ducts could be sufficiently drained,which had good effect and was not restricted by the obstruction location of hilar cholangiocarcinoma.The analysis of the measurement data was performed using t test,and the analysis of the count data was performed using χ2 test,and the survival curve was plotted using Kaplan-meier method.
Results:
In total, 72 jaundiced patients with hilar cholangiocarcinoma underwent surgical treatment: 31 had PTBD prior to operation while 41 did not had PTBD.There were significant differences in ALT((93.2±21.4)U/L vs.(207.4±65.1)U/L),AST((87.6±18.1)U/L vs.(188.9±56.6)U/L)and total bilirubin((68.8±12.6)μmol/L vs.(227.5±87.7)μmol/L)between the patients after treatment and those before treatment(

OBJECTIVES:
To develop a prediction model for postoperative prognosis in patients with cholangiocarcinoma (CCA) based on the expression of silence information regulator 2 (SIRT2).
METHODS:
The differential expression of SIRT2 between CCA and normal tissues was analyzed using TCGA and GEO databases. Gene set enrichment analysis (GSEA) was used to explore potential mechanisms of SIRT2 in CCA. The expression of SIRT2 protein in CCA tissues and normal tissues (including 44 pairs of specimens) was also detected by immunohistochemistry (IHC) staining in 89 resectable CCA patients who underwent surgical treatment in The First Affiliated Hospital of Bengbu Medical College between January 2016 and December 2021. The relationship between SIRT2 expression and clinicopathological characteristics and prognosis of CCA patients was analyzed. A survival prediction model for patients with resectable CCA was constructed with COX regression results, the calibration curve and the time-dependent receiver operating characteristic curve (ROC) were used to evaluate the performance of the constructed model, and the predictive power between this model and the AJCC/TNM staging system (8th Edition) was compared.
RESULTS:
SIRT2 mRNA was overexpressed in CCA tissues as shown in TCGA and GEO databases. IHC staining showed that SIRT2 protein expression in CCA tissues was significantly higher than that in adjacent non-tumor tissues. GSEA results showed that elevated SIRT2 expression may be involved in multiple metabolism-related signaling pathway, such as fatty acid metabolism, oxidative phosphorylation, amino acid metabolism, etc. SIRT2 expression level was related to serum triglycerides level, tumor size and lymph node metastasis (all P<0.05). The survival analysis results showed that the patients with higher SIRT2 expression had a significant lower overall survival (OS) than patients with lower SIRT2 expression (P<0.05). Univariate COX regression analysis suggested that pathological differentiation, clinical stage, postoperative treatment and SIRT2 expression level were associated with the prognosis of CCA patients (all P<0.05). Multivariate regression analysis confirmed that clinical stage and SIRT2 expression level were independent predictors of OS in postoperative CCA patients (both P<0.05). A nomogram based on SIRT2 for prediction of survival in postoperative CCA patients was constructed. The C-index of the model was 0.675, and the area under the time-dependent ROC curve (AUC) for predicting survival in the first, second, and third years was 0.879, 0.778, and 0.953, respectively, which were superior to those of AJCC/TNM staging system (8th Edition).
CONCLUSIONS
SIRT2 is highly expressed in CCA tissues, which is associated with poor prognosis in patients with resectable CCA. The nomogram developed based on SIRT2 may have better predictive power than the AJCC/TNM staging system (8th Edition) in prediction of survival of postoperative CCA patients.

ObjectiveTo reveal the effects of different microbial agents on quality of Lycii Fructus by comparing the differences in the contents of multiple types of chemical components in Lycii Fructus after the application of different microbial agents. MethodTaking Ningqi No. 7 as experimental material, four microbial agents, namely Peiyuan combined with Xinterui(TP group), Trichoderma harzianum combined with Bacillus subtilis(BW group), Genwuyou(MT group) and Junyiduo(JYD group), were applied, and no microbial agents was used as the blank group(CK group). Then the contents of total phenolics, total flavonoids, saccharides, amino acids, nucleosides and bases, betaine and other components in Lycii Fructus were determined by ultraviolet spectrophotometry(UV), high performance liquid chromatography(HPLC) and ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS/MS), and the methods such as multiple comparisons, principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA) were used to analyze the effect of different microbial agents on the quality of Lycii Fructus. ResultMicrobial agents had different effects on chemical components of Lycii Fructus. The content of total phenolics was the highest in the TP group, and it varied significantly from the CK group(P<0.05). The total flavonoid content was the highest in the BW group, followed by the TP group. Both polysaccharide and alduronic acid contents were the highest in the JYD group. Betaine content in the TP and BW groups were significantly higher than that in the CK group(P<0.05). For the determined 23 kinds of amino acids, most of them were the lowest in the JYD group, and the highest in the MT group, while the nucleoside bases were higher in the MT and BW groups. It indicated that Lycii Fructus from different treatment groups could be distinguished clearly based on the determined 45 chemical components. The result of PLS-DA showed that the major differential components in each group were polysaccharides, glucose, fructose, betaine, alduronic acid, asparagine, sucrose, threonine, total flavonoids, alanine and total phenolics. The results of PCA composite scores based on the main differential components showed that composite scores of chemical components in each group were BW group>TP group>MT group>CK group>JYD group. ConclusionThe application of microbial agents of BW, TP and MT can promote the quality improvement of Lycii Fructus, and the application of JYD can promote the accumulation of polysaccharides and alduronic acid to a certain extent, but the overall effect on the quality of Lycii Fructus is not clear. This study lays the foundation for the green and healthy development of Lycii Fructus industry.
