Objective To explore different features and influencing factors of 75 g oral glucose tolerance test (OGTT) and glycated hemoglobin Ale (HbAlc) levels in subjects with newly diagnosed diabetes and prediabetes of natural history of type 2 diabetes. Methods All subjects were classified by OGTT into four groups: (1) normal glucose test (NGT), 31 subjects at age of (48. 4±15. 3) yrs (29-75 years old); (2) impaired fasting glucose (IFG), 33 subjects at age of (50. 8±9. 8) yrs (38-72years old) ; (3) impaired glucose tolerance test (IGT), 34 subjects at age of (54. 5±11.4) yrs (33-74years old), (4) T2DM, 117 subjects at age of (54.3 ± 14.1) yrs (29-75 years old). Glucose metabolism was evaluated by results of OGTT and HbAlc levels. The insulin secretion function and insulin resistance (IR) were evaluated by HOMA-β, △I30/△G330, area under curve of insulin (AUCINS)and HOMA-IR respectively. Results (1) Significant changes of HbAlc values among groups were as following order: T2DM(7. 41%)>IGT(5. 85%)>NGT(5.21%) (P<0. 01). HOMA-β value in T2DM, IGT and IFG decreased by 53. 1% (P<0. 01), 29.3% (P<0. 01) and 23.4% (P<0. 05)respectively as compared with NGT group. HOMA-IR value in diabetes group was 1.66-fold of NGT (P<0.01), 1. 29-fold of IFG (P<0.001) and 1.44-fold of IGT (P<0.05). (2) Only 3 h blood glucose concentration (BG) in 75 g OGTT was independently and positively correlated with HbAlc level (r=0. 71, P<0. 01). △I30/△G330 ratio was independently and negatively correlated with both 1 h and 2 h BG of OGTT (P<0.01). AUCins was positively correlated with only 3 h BG of OGTT (P<0.01). HOMA-β was independently and negatively correlated with all OGTT results except 2 h BG(P<0.01). HOMA-IR was an independently and negatively correlative factor of all OGTT results (P<0. 01 or P<0. 05). TG level was independently and positively correlated to only fasting BG (P<0. 05), and waist circumference value had an independent and positive relationship with only 1/2h BG (P<0. 01). Independently correlative factors of OGTT changes included △I30/△G330, AUCINS,HOMA-β, HOMA-IR and circumference values. Only 3 h BG was probably an independent contributor to HbAlc variation. Conclusions There are obvious HbAlc differences among T2DM,IGT and NGT patients. When HbAlc values are over 8%, no significant changes of glucose and insulin levels at 75 g glucose load test are found among subjects.

Objective To investigate the toxicity of urban PM2.5 in Guangzhou on PC-12 cells.Methods PM2.5 was collected in Guangzhou city.PC-12 cells were cultured in vitro and divided into several groups,including the control group,PM2.5 groups with different concentrations and NAC pretreated group (pretreaed with 10 μmol/mL NAC followed with 100 μg/mL PM2.5 exposure).Cells were incubated with indicated stimulator for 24 h,then cell viability was checked with cell counting Kit-8 assay,the level of intracellular ROS was labeled using H2DCFDA fluorescence probe,cell apoptosis was measured by the flow cytometry and the expression of apoptosis-related proteins,including Cytochrome C,Caspase 9,Caspase 3 and PARP,were detected by Western Blot assay.Results PM2.5 has a strong toxicity on PC-12 cells when its concentration is over 25 μg/mL.After exposure for 24 h,the cell viability was markedly decreased.The results of flow cytometry and Western blot assay showed that PM2.5 enhanced the apoptosis of PC-12 cells with the upregulatios of Cytochrome C,Caspase 9,Caspase 3 and PARP.Pretreatment with NAC could significantly diminish PM2.5-induced PC-12 cell toxicity,decreased ROS generation and apoptosis of PC-12 cells,with the down regulations of apoptosis-related proteins.Conclusion PM2.5 can cause apoptosis of PC-12 cells by inducing oxidative stress,upregulating the Cytochrome C expression and activating Caspase9/3,which may be one of the mechanisms underlying PM2.5-induced neurotoxicity.

Objective:To study the protective effects of Danhong injection ( DH) on myocardial damage induced by doxorubicin ( DOX) in Lewis tumor bearing mice. Methods:The model of Lewis lung cancer in mice was established by underarm injecting tumor cells, and then randomly divided into four groups:the model control group, DOX group, DH group and DH+DOX group. After the experiment, myocardial and tumor tissue were separated from Lewis tumor bearing mice, and the excised tumors were weighted. The activities of lactate dehydrogenase ( LDH) , creatine kinase ( CK) , manganese superoxide dismutase ( SOD) , catalase ( CAT) and glu-tathione peroxidase ( GPx) , and the content of malondialdehyde ( MDA) were determined by a colorimetric method. Flow cytometry was used to determine the levels of apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential (△Ψm). Re-sults:Compared with that in the model control group, a significant decrease of tumor weight was shown in both DOX group and DH+DOX group (P<0. 01). DH had no significant influence on the anticancer function of DOX. The activity of LDH and CK, and the ap-optosis in myocardium cells significantly increased (P<0. 01). Compared with DOX group, the activities of LDH and CK, and the ap-optosis significantly decreased in DH+DOX group (P<0. 01). The activities of △Ψm, SOD, CAT and GPx significantly increased (P<0.05orP<0.01). ThecontentofMDAandROSgenerationbothdecreased(P<0.01).Conclusion:DHhasnosignificantin-fluence on the antitumor effect of DOX. The combination of DH and DOX shows cadioprotective effect on the myocardial damage through improving mitochondrial antioxidant defense capacity, ameliorating oxidative stress and maintaining △Ψm homeostasis.

?AIM:To establish a suitable normative reference value for electroretinogram ( ERG ) testing using electroencephalogram ( EEG) skin electrodes.?METHODS: The ERG was recorded in 51 eyes ( 30 people ) who were normal after ophthalmologic examination in our department from March to September 2015 using skin electrodes and contact lens electrodes. The recorded result was reviewed and analyzed, and all the testings were recorded by the routine program.?RESULTS: The 95% confidential interval, mean or median of values was defined in amplitudes and latencies of various responses. All the amplitudes results of skin electrodes were significantly lower than those of the contact lens electrodes and the ratio ( amplitudes of skin electrodes to those of the contact lens electrodes ) was 20% to 30%. The latencies results of skin electrodes were significantly shorter than those of contact lens electrodes and the ratio was 95% to 96%.?CONCLUSION:The EEG skin electrode used for patients with low compliance may provide valuable information of retinal function.

Objective To investigate the MRI and echocardiography manifestations of noncompaction of ventricular myocardium(NVM)and assess the role of MRI in the diagnosis of NVM by comparing it with echocardiography.Methods Fourteen cases of NVM diagnosed by echocardiography were examined with MRI,including scanning of black-blood sequences,double inversion recovery fast spin echo (DIRFSE)and triple inversion recovery fast spin echo(TIRFSE),and white blood sequence:fast imaging employ steady state acquisition(FIESTA).Scanning plane includes short axis view,four-chamber view and long axis view.Results Both MRI and echocardiography displayed involvement of left ventricles in thirteen cases and involvement of double ventricles in one case.Apexes of heart and the intermedius are commonly affected.MRI showed 54 segments and echocardiography showed 53 segments affected,and there is no significant difference between the capability of MRI and echocardiography(P=1.000).The affected myocardium consisted of two layers:subendoeardial noncompacted myocardium and epicardial compacted myocardium,and the ratio measurement of N/C by MRI was 3.37?0.89 and it was 3.19?0.82 by echocardiography.Noncompacted myocardium was characterized by prominent and excessive myocardial trabeculations and deep intratrabecular recesses,in which the blood flow was communicated with the ventricle.One case was complicated with ventricular aneurysm,and coronary arteriography was performed with unremarkable findings.One case underwent heart transplantation because of progressive heart failure, Gross findings demonstrated prominent muscular trabeculations with deep intratrabecular recesses,which coincided well with MRI findings.Conclusion The MRI manifestation of NVM is characteristic,and MRI with multiple series and planes is helpful in the diagnose of NVM.Compared with echoeardiography,MRI could display the pathological cardiac muscle more clearly,because of its high soft-tissue resolution and spatial resolution.

Objective To summarize and analyze the epidemiological and clinical characteristics of COVID-19 Omicron variant cases in makeshift hospital, and the influence of age, sex and vaccination status on the disease duration, so as to provide reference for the prevention and control of the COVID-19 epidemic. Methods The epidemiological and clinical characteristics of COVID-19 cases admitted to makeshift hospital of National Convention and Exhibition Center (Shanghai) from April 9 to May 31, 2022 were retrospectively described and analyzed, and further cohort analysis was conducted to determine the influence of age, sex and vaccination status on the disease duration of COVID-19 cases in the author's branch hospital. Results Among the 174 466 COVID-19 cases in makeshift hospital, most of them were male, accounting for 59.38%. The infected cases were mainly young and middle-aged people aged 18-59 years old, accounting for 83.50%, followed by 12.30% of the elderly group over 60 years old; the average hospital stay was 7.40 days; the proportion of patients with fever was less than 27.79%; 15.37% (26 817/174 466) of the patients complicated with underlying diseases, and the top three were hypertension, diabetes and coronary heart disease. The proportion of people who received COVID-19 vaccine accounted for 79.56% (13 799/17 956), of which the highest proportion of three doses was 44.09%. The disease duration of 17 956 COVID-19 cases in the author's branch of makeshift hospital was 10.18 (7.34, 13.05) days. The disease duration in the elderly group was the longest with 11.34 (8.35, 14.37) days, followed by 11.17 (9.07, 14.33) days in the preschool group, 10.37 (8.14, 13.34)· days in the middle-aged group, 10.07 (7.37, 12.37) days in the school-age group, and 9.34 (7.05, 12.16) days in the young group. There was significant difference in the overall distribution of disease duration among the five groups (H=550.479 P<0.01). The disease duration in each age group basically showed a V-shaped distribution. The disease duration was 10.27 (7.34, 12.57) days in males and 10.10 (7.25, 13.09) days in females, and there was no significant difference (Z=-1.505 P>0.05). The disease duration of vaccinated patients was 10.24 (7.35, 13.05) days, and that of unvaccinated patients was 9.47 (7.09, 12.47) days. There was significant difference between the two groups (Z=-4.338 P<0.01). Conclusions COVID-19 Omicron variant cases have a high proportion of males, mainly young and middle-aged, and the proportion of fever patients is less than 30%. The disease duration is significantly lower than that of the original strain in Wuhan, and shows "V" distribution with each age group. Sex had no effect on the disease duration. COVID-19 vaccination did not have a clinical effect on the disease duration.
