Objective To investigate the diagnosis,therapeutic method and choice of operative opportunity in patients with acute cholangitis.Method s We conducted a retrospective analysis of 142 patients with AC treated in our hospital from 2006 to 2010,of all acute cholangitis of severe type occurring in 34 patients.Results The cure rate of surgery group was much better than non-surgery group,and the death rate of emergency surgery group was much lower than elective surgery group.Conclusion The surgical treatment given to the patients with AC,especially ACST in early,was the effective method to cure thoroughly and decrease the mortality rate.

Objective To explore the mechanism underlying the induction of systemic lupus erythematosus (SLE) by estrogen, hydralazine and ultraviolet irradiation. Methods Peripheral blood mononuclear cells (PBMCs) were harvested from 10 patients with SLE and 9 normal human controls, and cultured with or without the intervention with estrogen, hydralazine or ultraviolet irradiation. The DNA methyltransferase-1 (DNMT1) activity of PBMCs was quantified by using DNMT activity/inhibition assay kit. Results No statistical difference was observed in DNMT1 activity between patients with SLE and normal controls (0.36 ± 0.24 vs 0.46 ± 0.17, P ＞ 0.05). A significant decrease was noted in DNMT1 activity in PBMCs from patients with SLE after intervention with estrogen (0.32 ± 0.18 vs 0.46 ± 0.17, t = 1.725, P ＜ 0.05), hydralazine (0.33 ±0.13 vs 0.46 ± 0.17, t = 1.739, P ＜ 0.05) and ultraviolet irradiation (0.30 ± 0.14 vs 0.46 ± 0.17, t = 1.739,P ＜ 0.05 ) compared with that from normal human controls. The treatment with hydralazine also induced an attenuation of DNMT1 activity in PBMCs from normal human controls (0.38 ± 0.12 vs 0.46 ± 0.17, P＜ 0.05).Conclusion Estrogen, hydralazine and ultraviolet irradiation can inhibit the DNMT1 activity of SLE patients,indicating that they may induce the initiation of SLE by altering the activity of DNMT1.

Objective To investigate the gene expression of methyl-CpG-binding protein 2 (MeCP2) and methyl-CpG-binding domain 2 (mbd2) in patients with systemic lupus erythematosus(SLE) and their significance in the pathogenesis of SLE. Methods Semiquantitative reverse transcriptase-PCR was applied to detect the mRNA expression of MeCP2 and mbd2 in PBMCs obtained from relieved (n=17), active (n=17) SLE patients and healthy controls (n=17). The correlations were further analyzed among these parameters. Results No significant difference was observed in the expression level of MeCP2 mRNA among active SLE patients, relieved SLE patients and healthy controls (P>0.05). The expression of mbd2 in relieved SLE patients was significantly higher than that in health controls (t=12.8, P<0.01), but lower than that in active SLE patients (t=20.0, P<0.01). The expression of mbd2 positively correlated with SLEDAI (r=0.737, P=0.0001) of patients with SLE, and a positive correlation was also observed between the expression of mbd2 and MeCP2 in healthy controls (r=0.550, P=0.0222). Conclusions The expression of MeCP2 and mbd2 may be mutually constrained in normal human, but this relationship seems to be disturbed in patients with SLE.

Objective To explore the causes of deep vein thrombosis in lower extremities (DVT). Meth-ods Retrospective analysis of 411 patients with DVT being treated in our hospital from 2004 to 2009. Results 301 (73.2%) cases were with definite causes and 110( 26.8%) cases without definite causes. 195 cases occurred follow-ing operations and 68 cases following wounds and fractures. 122 cases accompanied with medical conditions ,50 cases occurred following pregnancy or child birth,39 cases suffered from cancer, 19 cases suffered from infection of lower extremity or local lesion,67 cases had past history of DVT. Conclusions Suggest that surgery, wound and fractures, postpartum, cancer, chronic illness inducing long-term bed stay and past history of DVT might correlate with DVT.

Objective:To analyze the correlation between serum uric acid and clinical features of patients with novel coronavirus pneumonia(COVID-19).Methods:A total of 200 patients with COVID-19 admitted to Wuhan Lei Shen Shan hospital from January 20, 2020 to April 10, 2020 were included in this retrospective cohort study. The patients were divided into the hyperuricemia group and the non-hyperuricemia group. The data of patients were collected through electronic medical record system. SPSS 19.0 and Graphpad Prism 8.0 statistical software were used to compare clinical features, laboratory results, survival time, and prognosis of patients between hyperuricemia and non-hyperuricemia groups.Results:Compared with the non-hyperuricemia group, the hyperuricemia group showed a higher BMI and mortality( P<0.05)as well as higher white blood cell count, lymphocytes, serum creatinine, creatine kinase, cystatin C, myoglobin, interleukin(IL)-6 levels( P<0.05). Serum uric acid level was positively correlated with lymphocytes, hemoglobin, albumin, creatinine, creatine kinase, cystatin C, D-dimer levels while negatively correlated with IL-2 receptor and IL-8. The patients with hyperuricemia had significantly shorter survival time and worse prognosis than those without hyperuricemia( P=0.04). Conclusion:COVID-19 patients with hyperuricemia show higher mortality and worse prognosis compared with the patients with non-hyperuricemia.

Chronic urticaria （CU） is a common skin disease worldwide， and its incidence is increasing year by year in various regions. Clinical manifestations such as severe itching can affect normal work， sleep， and daily life and increase the negative psychological burden caused by stress， anxiety， and depression. Mast cell activation and degranulation induced by immunoglobulin（Ig）E hypersensitivity is one of the core pathogenic mechanisms of CU， and there is no cure. Antihistamines such as cetirizine and loratadine are preferred for the clinical treatment of CU. Although they can effectively improve clinical manifestations such as itchiness， long-term application can increase the risk of adverse reactions and drug resistance. The phosphatidylinositol kinase/serine-threonine protein kinase B（PI3K/Akt） signaling pathway， as a classical signaling pathway regulated by phosphatidylinositol and tyrosine kinase receptor （RTK）， is a key target regulating the production and release of cytokines in macrophages and affecting the migration of leukocytes and the activation of mast cells and inflammation， and it can be involved in a variety of metabolic processes， such as mast cell activation and degranulation induced by IgE hypersensitivity and abnormal activation of the complement system so that the PI3K/Akt molecular pathway could be an important target for the future eradication of CU. However， the mechanism and potential role of the PI3K/Akt signaling pathway in the treatment of CU are less reported in China. Now， this paper reviewed the molecular mechanism of PI3K/Akt signaling pathway regulation in the treatment of CU and provided corroborative evidence and therapeutic strategy choices for the treatment of CU with traditional Chinese medicine （TCM） from the perspectives of molecular regulation and network pharmacology analysis.
