The interactions between genetic variations and dietary factors in type 2 diabetes mellitus have attracted some attention. Several studies revealed that dietary carbohydrate quality and quantity and increased dietary fat intake might interact with genetic variations of type 2 diabetes mellitus and increase risk of this disease. Genome-wide association studies suggest that genetic variance may modulate the association between dietary pattern and type 2 diabetes mellitus.

OBJECTIVETo explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.
METHODSThe 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.
RESULTSAt the 15 min and 30 min point after anesthesia, SaO2 in GA group was significantly increased compared to that in the EA group (P < 0.05). At 15 min, 30 min and 60 min point after anesthesia, MAP in CSEA group was significantly increased compared to that in the EA group (P < 0.05). At 30 min point after anesthesia, HR in CSEA group was increased significantly compared to the EA group (P < 0.05). At 15 min and 30 min point after anesthesia, SaO2 in the CSEA group was increased significantly compare to the EA group (P < 0.05). Compared with preanesthesia (T0) in EA group, MAP, HR and SaO2 decreased significantly at 15, 30 and 60 min after anesthesia (P < 0.05). The fluctuation of the three parameters in GA and CSEA groups were relatively small (P > 0.05). As well as the comparison of abnormal ECG among the 3 groups was concerned, the incidence of ST-T changes in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia and at the time of surgery termination (P < 0.05, P < 0.01). The incidence of arrhythmia in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia (P < 0.05, P < 0.01). Compared with T0 in the same group, the incidences of ST-T changes and arrhythmia in GA or CSEA group at the time of 15, 30 and 60 min after anesthesia and at the time of surgery termination were significantly lower than that before anesthesia (P < 0.05, P < 0.01).
CONCLUSIONGA and CSEA have less impact on hemodynamics and have smaller incidence of abnormal ECG of old CHD patients with abdominal operation.

OBJECTIVETo identify the type of iron deposition and describe its amount, distribution and associated lesions, in order to support an etiologic diagnosis for hemochromatosis.
METHODSHematoxylineosin (HE) stain, reticular fiber stain, Masson's stain and Perl's iron stain were used to assess liver biopsies from 31 patients with hemochromatosis. The Ishak scoring system and Deugnier scoring system were used to assess the histological change in liver and to semi-quantify the excess of hepatic iron. Genetic testing results were received from a portion of the patients and used in analysis.
RESULTSOne patient had hereditary (-HFE) hemochromatosis complicated with Gilbert's syndrome, for which the pattern of iron deposition was similar to that of the four patients with Gilbert's syndrome. Iron accumulation appeared as fine granules predominating at the biliary pole of cells and was distributed throughout the lobule with a decreasing gradient spanning from the periportal to centrolobular areas. Mild chronic inflammation was found to be commonly associated with low stage fibrosis.One patient had HFE hemochromatosis complicated with hepatitis B virus infection, and the pattern of iron deposition resembled that in the eight patients with viral hepatitis, wherein the deposition was mainly in the sinusoidal cells and/or portal macrophages. Histological grading and fibrosis staging differed among patients. The five patients with blood disordered showed iron accumulation mainly in the periportal hepatocytes, but mesenchymal iron deposits were also present. The grade of inflammation, as well as of fibrosis,was mild. The five patients with alcoholic disease and the five patients with drug-induced hepatitis showed hepatic iron deposition in swollen or ballooned hepatocytes. The two patients with excessive iron supply showed iron deposition localized within the parenchymal and mesenchymal cells.
CONCLUSIONEtiologic diagnosis of hemochromatosis relies on both the type of iron deposition and the nature of associated lesions. Liver biopsy is necessary for both diagnosis and prognosis.

Objective:To observe the effect of high flow nasal cannula combined with nasopharyngeal airway on improving ventilation in obese patients under general anesthesia without intubation.Methods:A total of 86 obese patients under general anesthesia without intubation admitted to the Lianyungang Hospital of Traditional Chinese Medicine from January to October 2023 were prospectively selected and randomly divided into a control group and an observation group using a random number table method, with 43 cases in each group. The observation group was given high flow nasal cannula combined with nasopharyngeal airway ventilation, while the control group was given ordinary nasal cannula combined with head lifting ventilation. Two groups were compared in terms of perioperative respiratory function, blood gas indicators, hemodynamics, pulse oximetry (SpO 2), and complications. Results:There was a statistically significant difference ( F=7.548, P=0.001; F=7.658, P=0.002) in the final respiratory carbon dioxide pressure (PetCO 2) and oxygenation index (OI) between the two groups with different oxygen flow rates of 2 L/min, 4 L/min, and 6 L/min. The PetCO 2 and OI in the observation group were higher than those in the control group at 4 L/min and 6 L/min, and the difference was statistically significant (all P<0.05). There was a statistically significant difference ( F=10.024, P<0.001; F=10.236, P<0.001) in the oxygen partial pressure (PaO 2) and carbon dioxide partial pressure (PaCO 2) before anesthesia (T 0), 10 minutes after anesthesia (T 1), and at the end of surgery (T 2) between the two groups. The PaO 2 in the observation group was higher than that in the control group at T 1 and T 2, while the PaCO 2 was lower than that in the control group, and the difference was statistically significant (all P<0.001). The difference in mean arterial pressure and heart rate at T 0, T 1, and T 2 time points between the two groups was statistically significant ( F=8.476, P<0.001; F=8.321, P<0.001). The average arterial pressure and heart rate at time points T 1 and T 2 in the observation group were lower than those in the control group, and the difference was statistically significant (all P<0.001). The comparison of SpO 2 at T 0, T 1, and T 2 time points between the two groups showed a statistically significant difference ( F=7.548, P<0.001). The SpO 2 at T 1 and T 2 time points in the observation group was higher than that in the control group, and the difference was statistically significant (all P<0.001). The total incidence of complications in the observation group was lower than that in the control group ( P<0.05). Conclusions:High flow nasal cannula combined with nasopharyngeal airway can significantly improve perioperative respiratory function, blood gas indicators, and SpO 2 in obese patients undergoing general anesthesia without intubation, stabilize hemodynamics, and reduce the risk of complications.

OBJECTIVETo observe the duration of enterovirus-71 (EV71) and coxsackievirus A 16 (CoxA16) viral shedding in stool samples of children with hand, foot and mouth disease (HFMD) infected with EV71 and CoxA16 and to explore the relationship between the duration of intestinal virus shedding and the severity of illness of children with HFMD.
METHODTotally 113 laboratory-confirmed cases of children with HFMD infected with EV71 and CoxA16 were followed up. The stool samples were collected with the interval of 4 to7 days and the viral nucleic acids were detected by fluorescent PCR until the stool viral nucleic acids of infected children turned to be negative. The cases in EV71 group were further divided into "ordinary EV71 group" and "severe EV71 group" according to the severity of the illness. The positive rates of viral nucleic acid and the differences of distribution among different groups were analyzed by Kaplan-Meier survival analysis during the follow-up period.
RESULTThe 113 cases of infected children were grouped as follows: 65 cases of EV71 positive children, 44 cases of CoxA16 positive children, 4 cases of EV71/CoxA16 mixed infection. The median duration of the stool viral nucleic acids turning to negative was 26 (18.25-32.50) days in EV71 group and 27 (14.50-33.75) days in CoxA16 group (Z = 1.51, P > 0.05). At 1, 4, 6 and 10 weeks, the positive rates of stool viral nucleic acid of children with HFMD in EV71 group were 100%, 48.1%, 17.2% and 0 respectively. At 1, 4 and 6 weeks, the positive rates of stool viral nucleic acid of children with HFMD in CoxA16 group were 95.5%, 53.8% and 0 respectively (χ(2) = 0.18, P > 0.05). At 1, 4 and 6 weeks, the positive rates of stool viral nucleic acid of children with HFMD in ordinary EV71 group were 100%, 23.5% and 0 respectively, while at 1, 4, 6 and 10 weeks, the positive rates of stool viral nucleic acid of children with HFMD in severe EV71 group were 100%, 62.4%, 26.0% and 0 respectively (χ(2) = 5.689, P < 0.05).
CONCLUSIONThe duration of enterovirus shedding in stool samples of children with HFMD lasted for a long period. The maximum duration of EV71 and CoxA16 in stool of children with HFMD was 10 weeks and 6 weeks, respectively. The duration of intestinal virus shedding of children with HFMD infected with EV71 was related with the severity of the illness.
