Objective To investigate the apearance and characteristics of skin rashes in patients suffering from dengue fever.Methods Clinical data were retrospectively analyzed for 126 hospitalized patients with dengue fever collected from August to October,2007.Results Out of 126 patients with dengue fever,69.0% (87/126)had skin rashes,which usually developed from day 1 and 11 after fever.About 59.7%(52/87)of these patients developed skin rashes from day 3 to 7 after fever.No eruption order was evidenced in 59(67.8%)patients.Skin rashes were located in both the trunk and limbs in 38(43.7%)patients,and only in the limbs in 30 (34.5%)patients.The incidence rates of maculae,maculopapules,papules.hemorrhagic rash and mixed eruptions were 14.9%(13/87),14.9%(13/87),18.4%(16/87),26.4%(23/87)and 21.8%(19/87),respectively.Conclusions Most patients with dengue fever developed skin rashes from day 3 to 7 after fever.Limbs and trunk are predilection sites of skin rashes in dengue fever.Skin rashes in dengue fever is complex,including maculae,papules,hemorrhagic rashes,vesicles and mixed rashes.

UNLABELLEDObjective: In order to assess the integrative cardiopulmonary function after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD), we used symptom limited maximum cardiopulmonary exercise testing (CPET).

METHODSAll 59 patients diagnosed stable CAD by coronary angiography and echocardiography from August to December of 2014 in our hospital, were divided two groups. PCI group, 31 patients received PCI and drugs. Control group, 28 patients received drugs therapy only. All patients performed CPET before and after the treatment.

RESULTSAll patients safely completed CPET without any complications. The control group, all functional parameters were unchanged (P > 0.05). PCI group, the anaerobic threshold, peak oxygen uptake and peak oxygen pulse increased significantly (P < 0.05) from baseline,but not for others (P > 0.05). For individual analysis, PCI group had higher rates of increase (≥ 10% of baseline) in both peak oxygen uptake and peak oxygen pulse than those of control group (P < 0.05).

CONCLUSIONCPET is an objective, quantitative, safe and effective method to evaluate the clinical therapeutic efficiency. PCI can improve the integrative cardiopulmonary function in CAD patients.

OBJECTIVETo investigate the influence of total flavonoids of epimedium (TFE) on the streptozocin (STZ)-induced kidney injury in diabetic rats and discuss the possible mechanism.

METHODSDiabetes was produced by a single injection of streptozocin (40 mg/kg, iv) in male SD rats. The rats were randomly divided into three groups (n = 10): control group, model group and TFE group (100 mg/kg, ig). Animals were sacrificed 12 weeks later. The level of blood glucose, blood urea nitrogen (BUN) and creatinine (Cr) as well as the renal index were determined. Detect the specific biochemical of renal tissue: superoxide dismutase (SOD), malondialdehyde (MDA). Use masson staining to observe the morphology of the renal tissue. Immunohistochemistry was employed to determine the protein levels of transforming growth factor-beta1 (TGF-beta1).

RESULTSCompared to control group, the enhancement of blood glucose, renal index, BUN and Cr was found in model group, which was significantly attenuated by treatment with TFE. Meanwhile, elevated MDA level in renal tissue as well as decreased SOD activities in renal tissue were significantly remitted by TFE. Furthermore, TFE decreased the expression of TGF-beta1.

CONCLUSIONTFE can evidently relieve renal damage in rats with diabetic nephropathy induced by STZ, which might be related to antioxidation and modulating the expression of TGF-beta1 protein.

OBJECTIVETo investigate the effect of Manshuailing Oral Liquid (MSL) on left ventricular diastolic dysfunction (LVDD) in patients with heart disease.

METHODSNinety patients with LVDD were randomly divided into the conventional treated group (Group A, treated by conventional treatment with western drugs of cardiotonic, diuretic, coronary dilator, etc.) and the Chinese drug treated group (Group B, treated by conventional treatment plus MSL 2 times a day, 100 ml each time), 45 in each group. After 4 months treatment, the total heart failure coefficient (HFC) and cardiac functions were re-determined.

RESULTSAfter treatment, in both groups, the HFC lowered significantly (P < 0.05 or P < 0.01), the left ventricular peak velocity of early diastolic rapid filling (Emas) quickened, the left atrial systolic peak velocity (Amas) slowed down and Emas/Amas (E/A) enhanced, the isovolumetric relaxation time shortened. However, comparison between the two groups showed significant difference (P < 0.05) in either item, Group B was superior to Group A (P < 0.05). In the 62 patients with mixed heart failure, i.e. both systolic and diastolic dysfunction of left ventricle, Group B was superior to Group A in increasing ejection fraction, cardiac output and thickening rate of left ventricular posterior wall (P < 0.05).

CONCLUSIONMSL could improve the heart function of patients with LVDD, and alleviate their clinical symptoms.

OBJECTIVE: To investigate the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits' lungs. METHODS: Sixty-two rabbits were randomly divided into drowning group (n = 30), postmortem immersion group (n = 30) and land death group (n=2), and the diatoms in each lung lobe were analyzed quantitatively and qualitatively by microwave digestion and scanning electron microscopy. RESULTS: In the drowning group, the diatoms were detected in each lung lobe with Cyclotella and Melosira in the majority. In the postmortem immersion group, Cyclotella was in the majority. And the diatoms weren't detected in some lung lobes in postmortem immersion. There were significant differences in the detection rates of upper lobe of left lung, middle lobe and cardiac lobe of right lung in two groups (P < 0.05). CONCLUSION Based on the microwave digestion and scanning electron microscopy, the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits' lungs can be analyzed and used as references for testing theory.

AIMTo investigate the cellular signal transduction pathway of vascular smooth muscle cell (VSMC) proliferation stimulated by insulin-like growth factor-1 (IGF-1).

METHODSRabbit aortic VSMCs was cultured in 3 groups. Cell proliferating ability was determined by measuring cell number and mitochondrial dehydrogenase (MD) activity (MTT assay). Wortmannin (WT), the specific inhibitor of phosphatidylinositol 3-kinase (PI3K), was used to evaluate indirectly the possible involvement of PI3K. Western blotting was used to detect the protein expression of phosphatase PTEN. Diphosphate action of PTEN on its specific substrate diC16PIP3 was measured by green reagent method.

RESULTSIGF-1 (100 microg/L) increased cell number and MD activity by 2.8-3.8 fold. WT markedly inhibited VSMC proliferation and completely abolished the above effects of IGF-1. IGF-1 inhibited PTEN activity in a concentration-(10-100 microg/L) and time--(3 min-24 h) dependent manner (P < 0.01).

CONCLUSIONIGF-1 increases VSM proliferation by increasing PI3K activity and inhibiting PTEN activity.
