ABSTRACT
Objective To explore the value of bedside ultrasound used by ICU doctor in the rapid diagnosis of traumatic abdominal,and to evaluate the advantage of bedside ultrasound in the treatment decision.Methods 60 patients with traumatic abdominal blood in our hospital admitted to the ICU were selected.All patients were checked through bedside ultrasonography by physicians with professional training of ICU,bedside ultrasound and abdominal CT and abdominal flat piece of traumatic hematocelia,and compared the diagnosis of the time of the bedside ultrasound,abdominal CT and abdominal X -ray and ultrasound physician ultrasound examination.Results The difference of abdominal blood detection rate between bedside ultrasonography and abdominal computed tomo-graphy (CT)had no statistical significance (P >0.05);bedside ultrasonography of abdominal blood detection rate was higher than plain film of the abdomen,the difference was statistically significant (χ2 =73.346,P <0.01);bed-side ultrasound received a preliminary diagnosis of time -consuming (4.37 ±2.1)min was significantly lower than that of the examination of ultrasound physicians (13.86 ±5.6)min,abdominal CT (22.13 ±6.9)min and abdominal plain film (28.19 ±7.32)min,the differences were statistically significant (t =3.947,14.607,21.139,26.338,all P <0.01 ).Conclusion By the professional training of ICU physicians for bedside ultrasound traumatic blood abdominal patients can make a more accurate diagnosis,time -shorten,more accord with the requirement of treating critically ill patients in ICU,which has important clinical value for trauma abdominal blood in early rapid diagnosis and treatment.
ABSTRACT
Objective This study was designed to investigate the effect of matrine on high glucose‐induced tumor necrosis factor‐α(TNF‐α)and transforming growth factor‐β1 (TGF‐β1 ) overexpression in rat peritoneal mesothelial cells(PMCs) ,and to ex‐plore the possible mechanism in the peritoneal fibrosis .Methods ology The rat PMCs were incubated in vitro ,and then assigned in‐to 5 groups on the basis of the added drug concentrations :2 .5% glucose group (n=15 ,A);Glucose + 2 .5% matrine group (n=15 ,B);4 .25% glucose group (n=15 ,C);Glucose + 4 .25% matrine group (n=15 ,D);Blank control group (n=15 ,control group , added the DMEM/F12 medium) .The levels of TNF‐αand TGF‐β1 in the supernatants were measured by ELISA method at the dif‐ferent time (24h ,48h ,72h) ,and observed the changes of PMCs under the microscope .Results Compared with the groups of A ,C and D ,the PMCs in the control group and B group were small ,round ,spindle ,irregular or intensive .The expression of TNF‐αand TGF‐β1 in the A group was lightly higher than that of the control group ,but the level in the C group was significantly higher than that of the control group (P 0 .05 ) ,but the lever in the D group was significantly lower than that of the C group ( P< 0 .05 ) . Conclusion Matrine might be helpful to resist the overexpression of TNF‐αand TGF‐β1 induced by high glucose ,and then protect the PMCs .
ABSTRACT
Purpose To detect the expression of Snai2 mRNA in gastric carcinoma and normal gastric mucosa and analyze its significance.Methods Total RNA was extracted with TRIzol from 30 cases of gastric carcinoma and mRNA was transcribed reversely into cDNA.The expression of Snai2 mRNA was examined by real-time PCR; then mRNA probes were prepared, the expression of Snai2 mRNA was detected by in situ hybridization on a tissue array,including normal gastric mucosa (20 cases) and gastric carcinoma (100 cases).Results Real-time PCR data showed they had different expression in different degrees of differentiation of the cancer: the poorer differentiation, the more expression (P0.05).Conclusions Snai2 could be a biomarker of malignant degree and disease progression,and used as a useful tool for evaluation of prognosis.
ABSTRACT
Objective To study the status of prevalence of hyperlipidaemia among rural residents aged from 30 to 59 in Changzhou and provide evidence for taking prevention measures.Methods By the means of the cluster random sampling,a questionnaire survey and medical examination were conducted among 10 018 permanent residents in rural areas of Changzhou.The fasting plasma cholesterin(TC),triglycerides(TG),high density lipoprotein-C(HDL-C) were measured.Age-standardized prevalence rates were calculated by using the direct standardization method according to 2000 China population census.Results The prevalence of hyperlipidaemia of this population was 32.3%,the age-standardized prevalence was 31.3%,and the prevalence among men was significantly higher than women(P
ABSTRACT
Objective To evaluate the impacts of comprehensive diabetes intervention to provide evidence for effective diabetic control in rural communities.Methods Diabetic patients from four communities at Wujin District of Changzhou City were selected.One hundred and seventy-three patients from two communities received comprehensive intervention,including medication therapy,diabetes education,and diet.exercise,and behavior instruction(intervention group);142 patients from the other two communities got medication therapy only (control group).All the participants were interviewed with structured questionnaire and phyrsical examination.The second epidemic investigation was conducted at 4 years to evaluate the effects of the intervention.Results At the end of the intervention,the awareness rates of normal fasting plasma glucose,major diabetes risk factors,healthy diet,and therapeutic strategies in the intervention group were 90.8%.74.6%,89.6%,and 59.5%,respectively,which were significantly higher than those in the control group (all P<0.05).For the intervention group,the rates of diet behavior or physical exercise change were 68.8% and 58.4%.respectively.which were much higher than those of the control group(all P<0.05).The average levels of systolic pressure,diastolic pressure,fasting plasma glucose,and total cholesterol were (130.6±10.4)mm Hg(1 mm Hg=0.133 kPa),(78.4±7.5)mm Hg,(6.2±3.1)mmol/L,and (4.5±0.9)mmol/L,respectively,in the intervention group,which were lower than those in the control group(all P<0.05).Conclusion Comprehensive intervention shows significant effects on rural community patients with diabetes.
ABSTRACT
Purpose:To study if tamoxifen (TAM) can induce growth arrest and apoptosis of ER negative MA782 mouse breast cancer cell line and to explore the molecular mechanisims. Methods:MA782 cells were cultured in RPMI 1640 medium with TAM.The proliferative activity of cells was detected by MTT methods, and cells apoptosis by flowcytometric methods. The expression of cyclin D1, CDK4 and TGF ?1 proteins was detected by immunohistochemical methods, the semi quantification of protein expression was analyzed by pathological image analysis software.Results:TAM can induce growth arrest and apoptosis of cells. ICC results showed that MA782 cells were ER negative. There was no change of cell cycle regulators in cells with 2 ?mol/L TAM. After 48、72h with 6 ?mol/L or 10 ?mol/L TAM, the level of cyclin D1 proteins decreased from 132.5?0.02 to 129.67?0.03、126.18?0.03(6 ?mol/L) and 109.1?0.01、73.56?0.02(10 ?mol/L),CDK4 proteins decreased from 107.2?0.01 to 91.23?0.02、76.21?0.03(6 ?mol/L)and 83.52?0.02、72.03?0.01(10 ?mol/L), while TGF ?1 proteins increased from 59.72?0.02 to 83.2?0.04、121.75?0.03(6 ?mol/L)and 96.83?0.02、139.01?0.05(10 ?mol/L),The difference was significant( P
