Objective: To examine the significance and prognostic value of the classification of hilar cholangiocarcinoma based on actual anatomical location. Methods: A retrospective study was conducted including 120 patients of hilar cholangiocarcinoma treated at the Second Affiliated Hospital,Zhejiang University School of Medicine and Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2019 to December 2021. Patients with hilar cholangiocarcinoma were classified for seven types according to the site of tumor location. The clinicopathological and prognostic data of 120 patients were retrospectively analyzed(There were 57 males and 63 females,the age (M(IQR)) was 61(22)years(range:42 to 85 years)). All patients received radical resection without visible intraoperative tumor residue and negative bile duct resection margin according to intraoperative pathological biopsy. The classification variables were analyzed by Pearson χ² test or Fisher's exact probability test,one-way ANOVA or Kruskal-Wallis rank sum test.Kaplan-Meier method was used for survival analysis. Cox proportional risk model was used for prognostic factors. Results: The coincidence rate of preoperative surgical planning and actual operational styles was verified in 33 cases. Twenty-six cases were consistent,and 7 cases were inconsistent,with a coincidence rate of 78.8%. According to the actual anatomical location,patients in type of secondary branch experienced a significantly longer operation duration,a higher portal vein resection rate,margin positive rate and more advanced T stage(all P<0.05). The median overall survival time of the unilateral main trunck group was 27.0 months,and the bilateral group was 17.0 months. Survival analysis based on the tumor classification of the actual anatomical location showed that the unilateral or main trunck group predicted less aggressive clinical features and favorable outcomes(HR=1.931,95%CI:1.066 to 3.499,P<0.05). Multivariate analysis demonstrated that the actual anatomical location of the tumor type(HR=2.269,95%CI:1.333 to 3.861,P=0.003),combined liver resection(HR=0.464,95%CI:0.253 to 0.848,P=0.013) and N stage(HR=6.317,95%CI:3.083 to 12.944,P<0.01) were independent factors affecting the prognosis of patients. Conclusion: The classification based on the actual anatomy can be used as a promising scheme in refining patient stratification and predicting survival in hilar cholangiocarcinoma,and it can guide the selection of surgical methods,and predict operative safety and radical resection rate.

Alzheimer's disease （AD） is a deleterious neurodegenerative disorder， which has become a significant public health concern and economic burden. The pathogenesis of AD is complex and involves several hypotheses such as amyloid β-protein （Aβ） deposition， Tau protein hyperphosphorylation， oxidative stress， and inflammation. There is an urgent need for a holism-based comprehensive intervention with multi-pathway， multi-level， and multi-target characteristics， which demonstrates the unique advantage of traditional Chinese medicine （TCM）. Therefore， it is of great significance to conduct and promote research on TCM treatment of AD. Danggui Shaoyaosan （DSS） from the Synopsis of Golden Chamber （《金匮要略》） by ZHANG Zhongjing （150 AD-219 AD） was originally designed for reliving gynecological ailments. It is a classic TCM formula that modulates liver and spleen and dispels blood stasis and water retention. Since the late 1980s when Japanese researchers reported its therapeutic effect on AD， it has been widely used in the clinic with clear effects. The elucidation of the mechanism of this formula helps exert its effects. Hereby， this paper reviewed relative research progress and made an analysis in terms of attenuating aberrant accumulation of Aβ and hyperphosphorylated Tau protein， anti-inflammatory and antioxidant activities， mediating neurotransmitters， ameliorating lipid metabolism， modulating gut microbiota， reduced neuron apoptosis， decreasing intracellular Ca²⁺ overloading， and increasing the expression of estradiol. This paper is expected to provide references for understanding the scientific connotation of DDS in the treatment of AD and lay a solid foundation for further investigation.

OBJECTIVE: To study the effect of early continuous blood purification (CBP) on the prognosis of children with septic shock. METHODS: A prospective analysis was performed for the children with septic shock who did not reach the 6-hour initial recovery target and/or had a fluid overload of >10%. According to the treatment time of CBP, they were divided into an early group with 30 children and a conventional group with 28 children. The two groups were compared in terms of the start time of CBP and 28-day mortality rate, as well as the related indexes in the children who were cured. RESULTS: The early group had a significantly earlier start time of CBP than the conventional group (P<0.05). There were 25 children cured in the early group and 22 cured in the conventional group, and there was no significant difference in 28-day mortality rate between the two groups (P>0.05). The children who were cured in the early group had significantly shorter correction time of lactic acid, urine volume, and fluid overload than those in the conventional group (P<0.05). The children who were cured in both groups had significant reductions in the percentages of T-lymphocyte subsets at the beginning (P<0.05); on reexamination on day 7, the percentages of T-lymphocyte subsets were increased and were higher in the early group than in the conventional group (P<0.05). The children who were cured in the early group had significantly shorter duration of CBP treatment, duration of mechanical ventilation, and length of stay in the PICU than those in the conventional group (P<0.05). CONCLUSIONS For children with septic shock who do not reach the 6-hour initial recovery target and/or have a fluid overload of >10%, early CBP treatment can quickly control the disease, shorten the course of disease, and accelerate immune reconstruction.

Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

OBJECTIVE: To study the pathologic characteristics of bone marrow for CD5 positive small B cell lymphoma (SBL).
 METHODS: The pathologic profiles of 92 patients with CD5 positive SBL were retrospectively analyzed. The morphologic and immunophenotypic features were analyzed by flow cytometry and immunohistochemistry. IgH/CCND1 was examined by fluorescence in situ hybridization (FISH).
 RESULTS: A total of 92 patients with CD5 positive SBL were enrolled in this study, including 56 (60.9%) chronic lymphocytic leukemia /small lymphocytic lymphoma (CLL/SLL), 23 (25.0%) mantle cell lymphoma (MCL) and 13 other SBL (14.1%). Among the 13 other cases, 5, 4 and 4 cases were follicular lymphoma (FL), lymphoplasmacytic lymphoma (LPL) and splenic marginal zone lymphoma (SMZL), respectively. The frequency of patterns for bone marrow infiltration was as follow: diffuse pattern (19/92), mixed pattern (15/92), nodular pattern (9/92), interstitial pattern (8/92), and intrasinusodial pattern (2/92). All patients expressed CD19, CD20 and CD5. According to the immunophenotypic score system, all the CLL patients had 4-5 scores, while SMCL and other SBL patients had less than 3 scores. For the other SBL patients, 5 FL expressed CD10, while 3 FL, 1 LPL and 3 SMZL expressed CD23. There was a significant difference in the expression of CD23, sIgM, FMC7, CD11C and CD22 between the CLL and MCL groups (P<0.01). All 23 MCL patients expressed cyclin D1 and showed IgH/CCND1 gene translocation by FISH detection.
 CONCLUSION CD5 positive SBL includes a variety of types of lymphoma. Patterns of bone marrow for CD5 positive SBL are diversity. Immunophenotypic analysis by flow cytometry is essential in the diagnosis and differential diagnosis of CD5 positive SBL, especially for CLL.

The objective of this study was to evaluate the value of morphologic diagnosis for acute leukemia (AL), to explore the relation of morphologic diagnosis with immunology, cytogenetics and molecular biology diagnosis of AL and to analyze the onset characteristics of AL in 10 years. The samples of bone marrow and peripheral blood from 233 newly diagnosed cases of AL were collected during 2001-2011 years; the morphologic examination and immunologic, cytogenetic and molecular biologic examination (ICM) were carried out, the consistency of morphologic diagnosis with ICM diagnosis was compared, the onset characteristics of AL was analyzed. The results showed that: (1) the consistent rate of immunology, cytogenetics, molecular biology diagnosis with morphologic diagnosis was 84.3%. The order of consistent rat was AUL, M0 < M1 < HAL < M4 < M2 < M3 < M5 < ALL < M6, M7, AP; (2) Misdiagnosis always occurred among AUL, M0, M1, ALL and HAL or among M2a, M3v, M4 and M5. (3) In 233 cases, the highest ratio of blast was observed in M1 (92.5%), while the lowest ratio of blast was observed in M2 (49.5%). (4) AL occurred more frequently in males than that in female (147:86). (5) AL occurred in patients aged from 1 to 88 years. The median age was 41.5 for AUL, 40.8 for M0, 43.4 for M1, 46.3 for M2, 33.8 for M3, 42.6 for M4, 48.8 for M5, 77.3 for M6, 2.5 for M7, 65.0 for AP, 29.1 for ALL and 40.3 for HAL. (6) The number of patients in the later five years (139 cases) was significantly greater than that in the first five years (94 cases), especially the patients with M1, M2, M3, M4, and M5. It is concluded that morphologic diagnosis has important clinical value in the MICM diagnosis of AL. Attaching importance to the confusing cell morphology and onset characteristics of AL can improve the diagnostic accuracy.

OBJECTIVETo investigate the diagnostic value of serum CEACAM1 in patients with pancreatic cancer.

METHODSFifty patients with pancreatic cancer and 50 with chronic pancreatitis were examine for serum levels of CEACAM1 by enzyme-linked immunosorbent assay (ELISA). The cut-off values and area under curve (AUC) of CEACAM1 was obtained by receiver operating characteristic (ROC) curve. The diagnostic efficiency of the tumor markers for pancreatic cancer was assessed by the fourfold table.

RESULTSThe serum level and positivity rate of CEACAM1 in pancreatic cancer patients were higher than those in chronic pancreatitis patients (P<0.05). Based on the ROC curve, the cut-off values and AUC of CEACAM1 were 13.835 ng/ml and 0.780, respectively (P<0.05). In pancreatic cancer patients, the diagnostic sensitivities of the tumor markers decreased in the order of CEACAM1 < CA242 < CA19-9 (P<0.05), and the specificity in the order of CA242 < CA19-9 < CEACAM1 (P<0.05).

CONCLUSIONCEACAM1 shows a higher diagnostic sensitivity than CA19-9 and CA242 for pancreatic cancer, but due to its low specificity this marker alone is not sufficient for diagnostic purposes.
