Objective To investigate the regulatory effects and possible mechanisms of autophagy induction and bactericidal activity in muring bone marrow derived macrophages ( BMDMs) . Methods Murine BMDMs were isolated and cultured in vitro. Then standard strain of E. coli was used to infect BMDMs and cellular autophagy levels and AMPK activation were detected. We next modulated functions of AMPK by pretreating cells with the specific agonist or antagonist of AMPK. Then cellular AMPK activation, autophagy levels and bactericidal activity were observed after E. coli infection. Results In E. coli infected BMDMs,autophagy related molecules like LC3B and Beclin1 were upregu-lated,accompanied with elevated LC3Ⅱ/Ⅰratio. Phosphorylation of AMPK was also upregulated by E. coli treatment. Enhanced AMPK activi-ty by its agonist leads to increased cellular autophagy and bactericidal activity,whereas inhibition of AMPK by its suppressor downregulated autophagy and dampened bactericidal activity. Conclusion AMPK and its related signaling pathway is required for anti-bacterial response in macrophage,which is dependent on its function in upregulating autophagy related molecules and inducing autophagy.

ObjectiveTo investigate the expression and activity of histone deacetylase (HDAC) in prostate cancer.Methodshe pathological samples of 37 cases of PCa were collected. The mean age of the patients was 73 (53 - 88 ) years, the preoperative t-PSA was 81.69 ( 3.13 - 2000 ) ng/ml, Gleason score: 13 cases were ≤7, 24 cases were ＞7. Twenty-seven cases of BPH were set as controls. The mean age of the BPH patients was 69 (52 - 84) years, the preoperative t-PSA was 10.93 ( 1.11 - 55.07 ) ng/ml.Western blotting and colorimetric Assay kits were used to determine the HDAC expression and activity. The difference of HDAC activity in benign prostatic hyperplasia and prostate cancer was statistically analyzed.The correlation of the HDAC expression level and values of PSA and Gleason score was also assessed.ResultsHDACs were over-expressed in most cases of prostate cancer, the expression rates were HDAC1 :57％, HDAC2: 68％, HDAC3: 84％ and HDAC4: 73％, respectively. The HDAC activity (P ＜0.05)was significantly different between the prostate cancer and benign prostatic hyperplasia groups. The expression level of HDAC did not correlate with the values of PSA and Gleason score.ConclusionsHDAC was highly expressed and strongly active in prostate cancer. The results suggest that HDAC might be a potential target for the management of prostate cancer patients.

Objective To evaluate the clinical significance of improving the goal attainment rate by management of timely feedback of hypertension patients, which is carried out by using existing communication network. Methods Totally 423 hypertension patients who were hospitalized for treatment in Daping Hospital from Jan. 2012 to Jan 2013, the random numbers table was used to randomize the patients into 2 groups: control group (212 cases) and experiment group (211cases), the conventional treatment was used in control group. Besides the conventional treatment measures, the modern way of communication and network information platform was used by patients who timely feed back the blood pressure changing, and implement the cognitive treatment of hypertension at the same time in the experiment group. The Chi square test was used to compare the patient's medication compliance, the attainment rate and so on , the t test was used to compare the blood pressure in two groups of patients after the intervention. Results At the end of the intervention, the difference of heavy salt diet (reduced to 16.59%), regularly drinking (reduced to 13.74%), heavy sugar diet (reduced to 10.43%), abnormal blood lipid (reduced to 19.91%), smoking (reduced to 27.96%), the number of people who have a stable mood (up to 91.47%), body mass index (reduced to 29.38%) and exercise at ordinary times (reduced to 36.02%) were statistically significant (P< 0.05). Hypertension patients compliance increased significantly, of which the medical behavior of 84.83%, compared with 13.21%in the control group, there was statistically significant difference (χ 2=8.54,P< 0.05). And the awareness, treatment, success rate of blood pressure control were 94.79%, 84.36%, 82.94% in experimental group and 50.94%, 40.09%, 27.83% in control group, and the differences were statistically significant (P<0.05). Conclusion Use of the existing information interaction platform in order to strengthen the management of the blood pressure of hypertension patients and related cognitive behavioral intervention, the control of risk factors and treatment compliance have improved significantly. The remote interaction platform used to patients with hypertension management improve the attainment rate of high blood pressure.

Objective: To investigate the clinical treatment results of combined Tretinoin-chemotherapy protocol and kinetics of PML-RAR ? fusion gene in childhood acute promyelocytic leukemia(APL). Methods: Ten children with APL were involved in this study. Induction therapy was Tretinoin alone(6 cases),Tretinoin plus chemotherapy(3 cases) and arsenic trixode(1 case). Postremission therapy consisted of three consolidation courses with DA,MA or HA and a monthly maintenance therapy over 4-5 years. Monitoring of minimal residual disease was performed regularly by RT-PCR assay for PML-RAR ? at differential clinical stages. Results: Clinical complete remission(CR) was obtained in 9 cases (90%).After a median follow-up of 42 months(14-156 months), the estimated 5-year event-free survival was (56? 16.5)%.Four cases relapsed at 14-42 months after achieving CR and 5 cases remained continuing CR. PML-RAR ? fusion gene was positive in all cases at CR and turned negative gradually during consolidation and maintenance treatment. The duration of conversion to RT-PCR negative status varied from 6 to 42 months.Four patients who were persistent positive(2 cases) or converted to positive(2 cases) for PML-RAR ? relapsed. Conclusion: Continuous negative RT-PCR results are associated with long-term disease-free survival and may be considered as potentially curative. RT-PCR assay for detection of PML-RAR ?should be performed regularly during post-remission period. The hematological relapse could potentially be averted through treatment modification according to molecular monitoring results of PML-RAR ?.

Objective To evaluate the effectiveness of internet-based cognitive behavior therapy (CBT-I) on blood pressure in patients with hypertension comorbid with insomnia.Methods One hundred and six patients met the JNC-8 diagnostic criteria for hypertension and DSM-5 diagnostic criteria for insomnia were selected,and randomly assigned to CBT-I group (n=53) and regular treatment group (n=53).All the patients accepted relevant treatment for 8 consecutive weeks.Changes of systolic blood pressure (SBP),diastolic blood pressure (DBP),the sleep parameters and the anxiety and depression levels were observed between baseline and 8 weeks of follow-up.Results Compared with pre-treatment,SBP and DBP decreased significantly in both CBT-I group and regular treatment group (P＜0.01),the decrease was more significant in CBT-I group than in regular treatment group (P＜0.01).The sleep latency,sleep efficiency,bed time and rating anxiety scale were improved more significantly in CBT-I group than in regular treatment group (44.49 ± 22.75min vs.55.50 ± 34.96min;72.31％ ± 9.15％ vs.57.70％ ± 11.53％;302.65 ± 43.76min vs.262.70 ± 50.64min and 17.14 ± 6.45 vs.21.02 ± 6.64,respectively),the differences were of statistical significance (P＜0.05).In addition,no significant difference was found in the level of depression between CBT-I group and regular treatment group.Conclusion CBT-I can effectively shorten sleep latency,improve sleep efficiency,extend bed time and improve anxiety,meanwhile effectively lower the blood pressure of patients with hypertension comorbid with insomnia by optimizing sleep quality.

Objective To investigate the potential role of T follicular helper cells (Tfh) in the pathogenesis of autoimmune thyroid diseases by comparing the expression of C-X-C chemokine teceptor type 5 (CXCR5) and CD57 in Hashimoto's thyroiditis (HT) and Graves' disease (GD) thyroid tissues.Methods The expression of CXCR5 and CD57 proteins was determined by immunohistochemical analysis in 15 HT thyroid samples,18 GD samples and 10 normal thyroid samples.Results Immunohistochemical staining showed that CXCR5 and CD57 were mainly positive in cytomembrane and cytoplasm of the infiltrated lymphocytes both in HT and GD tissues,with much higher levels than that of normal thyroid tissues ( P ＜ 0.05 ).Both CXCR5 and CD57 were not significantly different between the HT and GD tissues.Conclusion CXCR5 and CD57 expressions were increased with a similar expression pattern in both of the two main autoimmune thyroid diseases( AITD),indicating that Tfh may participate inthe development and progression of AITD.

Objective: To investigate the effects of buccal acupuncture on analgesia, immune indicators, and expression levels of Survivin and Livin proteins in patients with advanced-stage primary liver cancer. Methods: Eighty patients with advanced-stage primary liver cancer were selected and divided into control and treatment groups according to the difference in treatment modalities, with 40 patients in each group. The control group received transcatheter arterial chemoembolization (TACE), and the treatment group received buccal acupuncture in addition to TACE. The recent efficacy, analgesic effect, liver function, serum tumor markers, Survivin and Livin protein expression levels in liver cancer tissue, and immune indexes were analyzed and compared between the two groups. Results: The objective response rate (ORR) and disease control rate (DCR) of the treatment group were 37.5％ and 77.5％, respectively, which were significantly higher than those of the control group (22.5％ and 52.5％), and the recent efficacy of the treatment group was significantly better than that of the control group (P<0.05). The onset of analgesia in the treatment group was significantly faster than that in the control group (P<0.05), the duration of analgesia was significantly longer than that in the control group (P<0.05), and the numeric rating scale (NRS) score of pain after treatment was significantly lower than that in the control group (P<0.05). In the treatment group, the aspartate aminotransferase (AST), alanine aminotransferase (ALT), and albumin/globulin (A/G) were significantly lower than those in the control group (P<0.05), and the serum levels of alpha-fetoprotein (AFP), alpha-L-fucosidase (AFU), and carcinoembryonic antigen (CEA) were significantly lower than those in the control group (P<0.05), and the expression levels of Survivin and Livin in liver cancer tissue were significantly lower than those in the control group (P<0.05); CD4+ and CD4+/CD8+ in the treatment group were significantly higher than those in the control group, and CD8+ was significantly lower than that in the control group after treatment (P<0.05). Conclusion: Buccal acupuncture can reduce the degree of pain and liver function damage in patients with advanced- stage primary liver cancer and lower the serum tumor marker levels, and its mechanism of action may be related to the down-regulation of Survivin and Livin protein expression levels in the liver cancer tissue and the regulation of the immune function.
