Objective To summarize the clinical experience of 3% sodium chloride in treatment of chronic heart failure with hyponatremia. Methods The 102 patients suffering from chronic heart failure with hyponatremia were treated with water limit, vasodilator, cardiotonic, diuretics, angiotensin-converting enzyme inhibitor, angiotensin Ⅱ receptor antagonist and 3% sodium chloride. Cardiac functional capacity classification (NYHA), treatment effect and hyponatremia level were compared between pre- and post- treatment. Results After treatment, heart function was statistically different as compared with that of pre-treatment (χ2=150.26, P＜0.05). The 58 cases showed distinct effect, 37 cases moderate effect, 7 cases no effect, and the percentage of total effect was 93.1%. The hyponatremia of patients with different level of heart function were (139.4±22.6) mmol/L, (138.2±23.3) mmol/L, the difference had a statistics significance compared with pre-treatment hyponatremia which were (122.9±20.5) mmol/L, (120.5±26.8) mmol/L (t=2.02, 2.04, P＜0.05). Conclusions Proper diuresis and sodium salt supplement could help to reduce the malignant risk of the patients suffering from chronic heart failure with hyponatremia and to improve the prognosis.

Objective To study the role of sodium nitroprusside in preventing pulmonary ische-mia-reperfusion injury and the possible mechanism. Methods Fourteen pigs were randomly divided into 2 groups: control group underwent controlled reperfusion with reperfusion solution (leukocyte-depleting blood modified buckberg perfusate = 4:1) for 10 min at lower pressure of 18 mm Hg and 37℃? 1℃ before removing the pulmonary artery clamp; experimental group were subjected to controlled reperfusion with reperfusion solution before removing the pulmonary artery clamp, followed by infusion of sodium nitroprusside (10?g?kg-1?min 1 for 10 min) via pulmonary artery. Blood oxygen pressure, pulmonary vascular resistance, pulmonary compliance and the changes in pulmonary oxygen-ation function were assessed 0. 5, 1 and 2 h later. After the trail, the contents of water, NO and MDA in pulmonary tissues were measured. Results In the experimental group, left lung oxygenation function and pulmonary compliance was significantly better (P

The severity of ischemic brain injury was closely associated with the mortality and disability of stroke. How to limit ischemic brain injm-y to the greatest extent and promote the recovery of neurological function is one of the most concerned hotspots at present in the field of neuroscience. A large number of studies have shown that a variety of factors involve in the pathological process of ischemic brain injury, in which, the role of T lymphocyte-mediated immune inflammatory response in ischemic brain injury has received increasing attention. This article mainly reviews the role of T cells in ischemic brain injury.

Objective To investigate the histological injury as well as the risk factors for the course of HBeAg-negative chronic hep-atitis B virus( HBV)-infected patients with persistently normal alanine aminotransferase ( ALT) levels ( PNAL) . Methods Ninty four patients of HBeAg-negative chronic HBV-infected with PNAL were performed liver puncturing. The ALT, HBV markers, and liver histo-logical changes were detected. The gender, age, family history, HBV-DNA and HBsAg levels were compared between different patients with liver inflammation and fibrosis. And the Logistic model was used during the analysis of independent risk factor. Results Among 94 cases, patients with inflammatory necrosis classification≥G2 accounted for 74. 5%, fibrosis grading≥S2 accounted for 27. 7%. Patients in the group of inflammatory necrosis classification≥G2 was older than the group of < G2, and the ALT level of≥G2 group was higher, as well as a higher HBV-DNA. What is more,Patients in the group of inflammatory necrosis classification ≥G2 were mainly male, and were associated with a family history of hepatitis B. Patients in the group of fibrosis stage ≥S2 was older than < S2 group, and the ALT level of fibrosis stage ≥S2 group was higher. And those patients were often associated with a family history of hepatitis B, but there was no significant difference among the HBV-DNA level and gender constitution. HBV-DNA and family history were the independent risk fac-tors of liver inflammation necrosis≥G2, and family history was the only independent risk factor of fibrosis stage≥S2. Conclusion The patients of HBeAg-negative chronic HBV-infected with PNAL, regardless of the ALT and HBV-DNA, must have a liver biopsy. The pa-tients with high level of HBV-DNA and with a family history of hepatitis B should be performed liver puncturing accordingly.

To investigate the character of esophageal manometry in reflux esophagitis(RE) with or without sliding hiatus hernia(SHH). Ambulatory 24 hours esophageal pH metry and esophageal manometry were studied in 50 patients with RE, and 50 RE patients with SHH. Lower esophageal sphincter(LES) competence was significantly boorer in SHH groups as compared with RE group, esophageal sphincter length(LESL) was (1 31?0 33)cm in SHH groups and (2 10?0 86)cm in RE group, and lower esophageal sphincter pressure(LESP) was (1 17?0 53) kPa in SHH groups and (2 16?0 65) kPa in RE groups( P

To compare the diagnostic value of X ray and endoscopy in reflux esophagitis (RE) in patients with hiatus hernia(HH) and their option in clinical practice. Correlative data of X ray and endoscopic findings in 50 cases of RE with HH were analysed.The radiography showed that there was 78 57% with the reflux type of suck and 64 29% with the clearance type of passivity in HH1 group, 81 82% with the reflux type of dumpage and 90 91% with the clearance type of delay in HH2 group. X ray and endoscopic diagnoses were corresponded 60% identically. Both examination methods are suitable for diagnosis of RE with hiatus hernia, X ray is the modality of first choice. Endoscopic exemination is indicated in cases of reflux esophagitis or other complications.

Objective:To observe the effects of myricetin on autophagy and mitochondrial fission in the human ovarian cancer SKOV3 cells,and to explore its induction effect on autophagy and promoting effect on mitochondrial fission.Methods: The SKOV3 cells were cultured in vitro.0,20,40,and 60 g·L-1 myricetin were used in control group and low, middle, high doses of myricetin groups for 12 h.The changes of mitochondrial membrane potential were detected by flow cytometry;the morphology of mitochondria was observed by MitoTracker Red;the expression levels of dynamin related protein1 (Drp1) and fission 1 (Fis1) in various groups were detected by Western blotting method;and the expression levels of autophagy related protein LC3 were detected by both Western blotting method and immunofluorescence method.Results:Compared with control group, the ratios of decreased mitochondria in different doses of myricetin groups were significantly increased(t=3.27, t=6.85, t=5.49,P<0.05).Compared with control group, the numbers of mitochondria in different doses of myricetin groups were increased, and the mitochondria looked more like gravel.Compared with control group,the expression levels of Drp1 in different doses of myricetin groups were significantly increased (t=4.35, t=3.28, t=6.17,P<0.05), and the expression levels of Fis1 were increased also(t=8.32, t=6.74, t=9.27).The immunofluorescence results showed that the expression levels of LC3 in different doses of myricetin groups were significantly increased with the increase of myricetin dose compared with control group.The Western blotting results showed that the ratios of LC3-Ⅱ/LC3-Ⅰ in middle and high doses of myricetin groups were significantly increased compared with control group(t=3.28, t=4.21,P<0.05).Conclusion: Myricetin can induce the autophagy of SKOV3 cells, and it can also promote the mitochondrial fission.
