Objective To investigate the clinical features of diabetes mellitus complicating with pneumonia in old people,and to improve the diagnose and treatment tactics.Methods In this retrospective analysis,the symptom of respiratory tract,body temperature,hemogram,radiologic characteristics,etiologic characteristics,the use of antibiotic and the course of disease of 30 old patients T2DM complicated by pneumonia and 34 the aged with pneumonia were compared.Results There were statistically significant differences in the use of drug and the course of disease among the two intervention groups.By contrast,the incidence of the symptom of respiratory tract,body temperature,hemogram,main etiologic agents,and the radiologic characteristics,such as empyema did not show significant differences in this investigation.Conclusions The keys to treating diabetes mellitus complicated by pneumonia are the severe control of blood glucose,application of two or more than two effective antibiotics.And the former,s course is longer.

Objective:To investigate the inhibitory effects of cytokine induced-killer(CIK) cells combined with docetaxel(DTX) on the expansion of lung adenocarcinoma cell line SPC-A1/DTX in vitro and in vivo.Methods:Peripheral blood mononuclear cells(PBMC) from healthy donors were incubated in vitro to induce CIK cells in the presence of interferon-gamma(IFN-?),IL-2 and anti-CD3 monoclonal antibody.MTT assay was employed to evaluate the cytotoxic activity of DTX,CIK cells and their combination against SPC-A1/DTX cells in vitro.SPC-A1/DTX lung adenocarcinoma cells were injected subcutaneously into nude mice.On the 14 th day,normal saline(control group),docetaxel(DTX 1 mg/kg in 0.2 ml,DTX group),CIK cells(1?107,CIK group),and CIK cells combined with docetaxel(CIK+DTX group) were administered intraperitoneally respectively.All the nude mice were sacrificed at day 15 after treatment and the tumor were weighted out.Results:MTT assay showed that the IC50 to docetaxel in SPC-A1/DTX cells was 110.5 ?g/ml and 8.5 ?g/ml in wild SPC-A1 cells.CIK cells possessed a higher anti-tumor cytotoxic activity in SPC-A1/DTX cells in vitro than in wild SPC-A1 cells(P

Cytokine-induced killer(CIK) cells are heterogeneous lymphocytes generated by incubation of human peripheral blood mononuclear cells with various cytokines in vitro,characterized by both the T lymphocyte's powerful cytotoxic activity and the natural killer(NK) cell's non-major histocompatibility-restricted antitumor activity in vitro and in vivo.CIK cells have their peculiar superiority over standard lymphokine activated killer(LAK) cells,tumor-infiltration lymphocytes(TIL) and anti-CD3 antibody induced activated killer(CD3AK) cells in application to the cancer adoptive immunotherapy and have hence received wide attention from researchers.This article updates recent researches on CIK cells,their interaction with dendritic cells,bispecific antibodies and oncolytic viruses,as well as their use in gene transfer.

Objective To evaluate the cardioprotective effect of trimetazidine in elderly patients with myocardial ischemia and chronic heart failure of coronary artery disease. Methods Eighty nine patients with angiographically proven coronary artery disease were randomized to therapy group (n=45) and controlled group (n=44). The patients in therapy group were given both the routine treatment and trimetazidine 20 mg, 3 times daily, for 6 months. The patients in controlled group were given only the routine treatment. Results After the therapy, the episode of angina pectoris every week was fewer and weekly consumption of nitroglycerin tablets was less in patients of therapy group than those in controlled group: (3.0?1.7 )episodes/w vs (3.9?2.1 )episodes/w,P0.05). Work load were increased 〔(10.2? 2.2) vs( 9.3 ?1.7)METs, P

Objective To evaluate the effects of different interventios on insulin resistance and ?-cell function in population with impaired glucose tolerance(impaired glucose tolerance,IGT).Methods The total of 382 cases of IGT were divided into five groups according to interventions:control(C),diet plus exercise group(D+E),Acarbose Group(A),Metformin(M)and traditional Chinese medicine Group(TCM),with each group making the appropriate intervention programmes.BMI,FPG,2hPG,F-Ins,P-Ins,F-CP and P-CP were determined before intervention and yearly during the follow up,and BMI,HOMA-IR,HOMA-? were calculated.Results By the end of the study,insulin,F-CP,IR Group D+E and FPG,2hPG,insulin,C-peptide,IR in the other groups were significantly lower than before the intervention(P

Objective:To explore the value of cell division cycle 42 (CDC42) in the efficacy and prognosis evaluation of arterial infusion chemotherapy for pancreatic cancer.Methods:The clinical data of 100 patients with pancreatic cancer who underwent arterial infusion chemotherapy from January 2018 to January 2020 at Second People's Hospital of Wuhu were retrospectively analyzed, and all patients were divided into effective group (the complete remission and partial remission) and ineffective group (the stable disease and the progressive disease) according to the chemotherapy efficacy determined by CT. The clinicopathological characteristics of both groups were compared. The influencing factors of chemotherapy efficacy were determined by using multivariate logistic regression model analysis. The efficacy evaluated by CT examination was treated as the gold standard. The receiver operating characteristic (ROC) curve was used to analyze the value of CDC42 level predicting the efficacy of arterial infusion chemotherapy for pancreatic cancer patients before infusion chemotherapy. Survival analysis was performed by using Kaplan-Meier and log-rank test was also performed.Results:Among 100 patients with pancreatic cancer, there were 13 cases of complete remission, 30 cases of partial remission, 20 cases of stable disease, 37 cases of progressive disease; 43 cases in effective group and 57 cases in ineffective group. The proportions of tumor long diameter > 4 cm, TNM staging Ⅲ-Ⅳ, carcinoembryonic antigen (CA)199 > 37 U/ml, carcino-embryonic antigen (CEA) > 5 ng/ml, neutrophil-to-lymphocyte (NLR) > 2.8, serum total bilirubin > 34.2 μmol/L before infusion, CDC42 ≤ 1.11 μg/L, low differentiation degree and vascular invasion in ineffective group were higher than those in effective group (all P < 0.05). Tumor long diameter > 4 cm, TNM staging Ⅲ-Ⅳ, CA199 > 37 U/ml, CEA > 5 ng/ml before infusion, low differentiation degree, vascular invasion, and CDC42 ≤ 1.11 μg/L were independent risk factors for effectiveness of arterial infusion chemotherapy (all P < 0.05). The area under the ROC curve of CDC42 predicting the ineffectiveness of arterial infusion chemotherapy was 0.810 (95% CI 0.781-0.839, P <0.01), and the optimal cut-off value was 1.11 μg/L, the sensitivity was 96.25%, and the specificity was 63.13%. Survival curve analysis showed that the 2-year overall survival rate of patients with CDC42 > 1.11 μg/L was 58.93% which was greater than that of patients with CDC42 ≤ 1.11 μg/L (22.73%), and the difference was statistically significant ( χ2 = 14.99, P<0.001). Conclusion:CDC42 level is an independent influencing factor for the efficacy of arterial infusion chemotherapy in patients with pancreatic cancer, and it can effectively predict the prognosis of patients.

Developmental exposure to bisphenol A (BPA), an endocrine-disrupting contaminant, impairs cognitive function in both animals and humans. However, whether BPA affects the development of primary sensory systems, which are the first to mature in the cortex, remains largely unclear. Using the rat as a model, we aimed to record the physiological and structural changes in the primary auditory cortex (A1) following lactational BPA exposure and their possible effects on behavioral outcomes. We found that BPA-exposed rats showed significant behavioral impairments when performing a sound temporal rate discrimination test. A significant alteration in spectral and temporal processing was also recorded in their A1, manifested as degraded frequency selectivity and diminished stimulus rate-following by neurons. These post-exposure effects were accompanied by changes in the density and maturity of dendritic spines in A1. Our findings demonstrated developmental impacts of BPA on auditory cortical processing and auditory-related discrimination, particularly in the temporal domain. Thus, the health implications for humans associated with early exposure to endocrine disruptors such as BPA merit more careful examination.
