Cholangiocarcinoma is a highly malignant disease with low surgical resection rate. It’s resistant to chemoradiotherapy and the prognosis of cholangiocarcinoma is poor. Although immune checkpoint inhibitors (ICIs) have achieved great success in tumor therapy in recent years, patients with cholangiocarcinoma have a poor response to immunotherapy, because of the complexity and diversity of immune microenvironment. Therefore, understanding the composition and characteristics of the immune microenvironment of cholangiocarcinoma, regulating targets in immune microenvironment, and adopting ICIs combined therapy, is important for immunotherapy for cholangiocarcinoma.

Gallbladder cancer is a high malignancy which is predisposed to invade adjacent organs and have lymph node metastasis. Gallbladder cancer is not sensitive to radiotherapy or chemotherapy with the worst prognosis among biliary tract cancers. At present, radical resection is the only possible method to cure gallbladder cancer. However, there are still many controversies about the surgical strategies, the extent of liver resection and lymph node dissection, and the treatment of incidental gallbladder cancer. In addition, under the background of the great success of immunotherapy and targeted therapy in a variety of solid tumors, it is also a question worthy of further considerations that whether the status of surgery in the treatment of advanced gallbladder cancer will be changed in the near future.

Objective:To construct a self-management behavior intervention scheme for diabetic patients based on Health Action Process Approach (HAPA) and to explore its application effects in patients with diabetes mellitus.Methods:By the convenient sampling method, patients with type 2 diabetes mellitus who were hospitalized in the First Hospital of Jilin University were selected as research objects. According to the random number table method, they were divided into the control group ( n=61) and the experimental group ( n=67) . Patients in the control group were given conventional nursing methods while patients in the experimental group were given the intervention scheme based on HAPA. Summary of Diabetes Self Care Activities (SDSCA) and Chinese version of Diabetes Distress Scale (DDS) were used to assess the self-management level and distress before and after intervention. Results:Before intervention, there were no statistically significant differences in SDSCA scores in all dimensions between the two groups ( P>0.05) . After intervention, SDSCA scores in all dimensions were higher in the experimental group than in the control group, and the differences were statistically significant ( P<0.05) . Before intervention, there were no statistically significant differences in DDS scores in all dimensions between the two groups ( P>0.05) . After intervention, DDS scores in all dimensions in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The self-management intervention scheme based on HAPA can improve the self-management behavior of diabetic patients and reduce their psychological distress.

Objective: To study the relationship between insulin resistance (IR) and coronary collateral circulation in patients with impaired glucose tolerance (IGT). Methods: A total of 227 patients with coronary angiography (CAG) were studied. There were 131 patients with male gender and the average patient’s age was (53.2 ± 11.0) years. IR (HOMA2-IR) index was measured by HOMA2 method, the severity level of coronary stenosis was assessed by Gensini scoring system, collateral circulation condition was determined by Rentrop classiifcation. 187 IGT patients were divided into 4 groups: Rentrop 0 group,n=55, Rentrop 1 group,n=42, Rentrop 2 group,n=39 and Rentrop 3 group,n=51; in addition, Control group,n=40 patients with normal glucose tolerance and coronary stenosis<50%. Results: Compared with Control group, all patients in 4 Rentrop groups had increased 2h-PBG, HbA1c, HOMA2-IR and Gensini score, while decreased fasting insulin (FINS), allP<0.05. Compared with Rentrop 3 group and Rentrop 2 group, the patients in Rentrop 1 group and Rentrop 0 group had elevated 2h-PBG, HbA1c, HOMA2-IR and Gensini score, while Rentrop 0 group had reduced FINS, allP<0.05. Multivariable regression analysis showed that HOMA2-IR index (R=0.518,P<0.05), HbA1c (R=1.916, P<0.05), 2h-PBG (R=2.130,P<0.05) and FINS (R=1.547,P<0.05) might be related to the severity of coronary stenosis. Binary regression analysis indicated that poor collateral circulation (the patients in Rentrop 0 group and Rentrop 1 group) was related to HOMA2-IR index (OR=1.679, 95% CI 1.101-2.558,P=0.016). Conclusion: HOMA2-IR index could be signiifcantly higher in patients with IGT combining chronic coronary occlusion. IR was the independent risk factor for the severity of coronary stenosis and coronary collateral formation.

OBJECTIVETo investigate the relationship between cytogenetic markers with World Health Organization (WHO) classification, disease progress and prognosis in cases with primary myelodysplastic syndromes (MDS).
METHODS298 patients with de novo MDS from the first affiliated hospital of medical school, Zhejiang University were enrolled in the retrospective analysis of WHO classification, karyotype, and prognosis. Follow-up study was also conducted.
RESULTSThe WHO classifications at first diagnosis were as follows: refractory cytopenia with unilineage dysplasia (RCUD), 18 cases; refractory anemia with ring sideroblasts (RARS), 8 cases; refractory cytopenia with multiline dysplasia (RCMD), 104 cases; refractory anemia with excess blasts-1, 76 cases; refractory anemia with excess blasts-2, 85 cases; MDS unclassified (MDS-U), 5 cases involved; and single del (5q), 2 cases. 39.6% of MDS patients carried karyotypic abnormalities. Among them, the frequency of numerical abnormalities, structural abnormalities and the existence of composite abnormalities were 45, 31, and 42, respectively. The composite abnormalities were unbalanced translocations and complex chromosomal abnormalities. The incidence of both karyotypic abnormalities and complex chromosomal abnormalities in RAEB group was higher than that in non-RAEB group (P<0. 05). An analysis based on IPSS-R Scoring System showed that advanced risk stratification (except the low-risk group) gradually enhanced the incidence of karyotypic abnormalities (P<0.05). In addition, the probability of evolution to leukemia increased with the higher IPSS-R score (P<0.05). In RAEB group, the cases with +8 chromosome, accounting for 19.5% of karyotypic abnormalities, had worse prognosis than those with normal chromosomes.
CONCLUSIONKaryotype was identified with an independent risk factor in MDS patients. Therefore, the information on cytogenetic analysis was critical for diagnosis, prognosis and individual treatment. MDS patients presenting+8 chromosome, an intermediate risk factor, were associated with a poorer outcome compared to cases with normal chromosomes in RAEB group.

Objective To investigate the effects of 10 mg and 20 mg atorvastatin and 10 mg rosuvastatin on inflammatory factors in patients with acute coronary syndrome (ACS).Methods 66 patients with ACS were randomly divided into three groups:the 10 mg atorvastatin group,the 20 mg atorvastatin group and the 10 mg rosuvastatin group(n=22 for each group).The levels of blood lipids,serum matrix metalloproteinases-9 (MMP-9)and plasminogen activator inhibitor-1 (PAI-1)were measured before and after two-week treatment.19 patients with normal coronary angiography were assigned to the control group.Results The concentration of serum MMP-9 and PAI-1 was higher significantly in patients with ACS than those in control subjects(P<0.05 or P<0.01).After two weeks'treatment,the serum MMP-9 and PAI-1 levels were lowered significantly (P<0.01),which were much better in groups of 20mg atorvastatin and of 10mg rosuvastatin than those in group of 10mg atorvastatin (P<0.05 or P<0.01 ).No relationship was observed between the levels of above inflammatory markers and serum hpids levels(P>0.05).Conclusion 10 mg Rosuvastatin can greatly reduce the serum level of MMP-9 and PAI-1 as compared to 10 mg atorvastatin in patients with ACS ,equivalent to the effect of 20 mg atorvastatin,suggesting that the anti-inflammatory effect is independent of lipid-lowering action.
