ABSTRACT
Objective Determination of polysaccharide content in dried peel seeding watermelon, and its mechanism of lowering blood glucose.Methods The content of polysaccharides in dried peel of seeding watermelon was determined by the method of phenol-sulfuric acid.Mice were given starch and sucrose load,and the mouse blood glucose was examined.The inhibitory activities of seeding watermelon against α-glucosidase were tested by the colorimetry of pNPG.Results The calibration of polysaccharide was A=0.066 4 C+0.022 6, R2=0.999 5, the content of polysaccharide in dried peel of seeding watermelon was 4.45% (n=10,RSD=1.80%);50,100 and 150 mg·kg-1 of polysaccharide could significantly reduce the starch load in mice blood glucose(P<0.01);100 and 150 mg·kg-1 of polysaccharide significantly reduced sucrose load blood glucose(P<0.01);polysaccharide concentration in 18 mg·mL-1 could significantly inhibit the activity of α-glucosidase as the inhibitory rate was (73.19±3.45)% (n=10).Conclusion Seeding watermelon polysaccharide has effect on lowering blood glucose in starch and sucrose load mice, and inhibits α-glucosidase significantly.
ABSTRACT
Objective To explore the effect and side effects of Group A Streptococcus Preparation(Sapylin)com-bined with mitomycin and lentinan combined with mitomycin in treating malignant pleural effusion through intrapleural catheter.Methods 70 malignant pleural effusion patients were selected in this study.All the patients were randomly divided into Sapylin group and lentinan group.One case with penicillin positive of the Sapylin group was adjusted to enter the lentinan group.After drainage of pleural effusion,the patients were divided into Sapylin group (34 patients) and lentinan group (36 patients).For the Sapylin group,Sapylin was prior injected and mitomycin was posterior injected.For the lentinan group,lentinan was prior injected and mitomycin was posterior injected.The side effects and clinical effect were observed and reported.Results The effective rate of Sapylin group was 85.3%,whereas 83.3%of lentinan group.There was no significant difference between the two groups(χ2 =0.051,P =0.822).Both groups had the following minor side effects:chest pain,fever,vomit and decreased white blood cells.No liver or renal injuries were reported.Conclusion The clinical outcomes of Sapylin combined with mitomycin and lentinan combined with mitomycin are both positive,in addition,the side effects are minor.
ABSTRACT
<p><b>OBJECTIVE</b>Since 1986, the reference of birth weight for gestational age has not been updated. The aim of this study was to set up Chinese neonatal network to investigate the current situation of birth weight in China, especially preterm birth weight, to develop the new reference for birth weight for gestational age and birth weight curve.</p><p><b>METHOD</b>A nationwide neonatology network was established in China. This survey was carried out in 63 hospitals of 23 provinces, municipalities and autonomous regions. We continuously collected the information of live births in participating hospitals during the study period of 2011-2014. Data describing birth weight and gestational age were collected prospectively. Newborn's birth weight was measured by electronic scale within 2 hours after birth when baby was undressed. The evaluation of gestational age was based on the combination of mother's last menstrual period, ultrasound in first trimester and gestational age estimation by gestational age scoring system.</p><p><b>STATISTICAL ANALYSIS</b>the growth curve was drawn by using LMSP method, which was conducted in GAMLSS 1.9-4 software package in R software 2.11.1.</p><p><b>RESULT</b>A total of 159 334 newborn infants were enrolled in this study. There were 84 447 male and 74 907 female. The mean birth weight was (3 232 ± 555) g, the mean birth weight of male newborn was (3 271 ± 576) g, the mean weight of female newborn was (3 188 ± 528) g. The test of the variables' distribution suggested that the distribution of gestational age and birth weight did not fit the normal distribution, the optimal distribution for them was BCT distribution. The Q-Q plot test and worm plot test suggested that this curve fitted the distribution optimally. The male and female neonatal birth weight curve was developed using the same method.</p><p><b>CONCLUSION</b>Using GAMLSS method to establish nationwide neonatal birth weight curve, and the first time to update the birth weight reference in recent 28 years.</p>

Objective To explore the characteristics of oxygen uptake efficiency (OUES) in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and analyze the relationship between OUE and severity of disease.Methods Pulmonary function test,polysomnogram and cardiopulmonary exercise testing were performed in 35 patients with OSAHS and 25 age-matched healthy volunteers.Their successive breathing respiratory exchange parameters were collected and analyzed.And t and x2 tests were used for 2 sample comparison.Correlation analysis was performed by Pearson correlation test.Results Significant differences in peak VO2 and peak VO2 ％ pred existed between OSAHS and normal control groups [(18±4) vs.(28 ±6) L/min,P＜0.01;(68±14) vs.(84±16) ％,P＜0.01].Compared with normal control group [(2.3 ±0.5) L · min-1 · lg-1 ; (36 ±4) ml/L; (36 ±4) ml/L],OUES,OUEP and OUE@AT of OSAHS group [(1.8 ± 0.4) L · min-1 · lg-1 ; (31 ± 5) ml/L; (30 ± 5) ml/L] were significantly lower (t =3.78-4.49,all P ＜0.01).And OUES,OUEP and OUE@AT in OSAHS patients were correlated (r =0.53-0.67,all P ＜0.01) positively with exercise tolerance (peak VO2％ pred) while negatively with apnea hypopnea index (AHI) (r=-0.67--0.54,all P ＜0.01).Conclusion The oxygen uptake efficiency of patients with OSAHS is significantly reduced compared to that of normal subjects.And it is correlated negatively with severity of disease.
ABSTRACT
Objective To explore a salvaging and nursing pathway of gas gangrene following trauma during seismic disaster.Methods The contingency plan of prevention was invocated to physically and psychologically salvage and nurse 18 sufferers having gas gangrene following trauma. Results The illness state of 18 sufferers were all effectively controlled and straightened up.The psychic trauma were pacified and no cross infections took place.Condusions Contingency plan of prevention from gas gangrene directs medical staff how to salvage gas gangrene after disaster,ensure the unblock green life passage for salvaging of patients with gas gangrene.
ABSTRACT
Objective To compare the Occurrence rate of unplanned extubation(UEX)and anastomotic leakage by two different gastric tube for gastrointestinal decompression in patients after the operation of esophageal carcinoma.Methods Three hundred and eighty patients were randomly divided into two groups,the experimental group(n=90),ballonet gastric tubes were used;the control group(n=90),general gastric tubes were used.The occurTence rate of unplanned extubation(UEX)and anastomotic leakage were investigated.Results There was a remarkable difference(P＜0.01)in the rate of UEX between the experimental group and the control group.Though no statistical difference was seen in the rate of anastomotic leakage(P＞0.05),lower incidence of anastomofic leakage was seen in the experimental group.Conclusions BalIonet gastric tube for gastrointestinal decompression in patients after the operation of esophageal carcinoma can reduce the rate of UEX,improve the nursing qualiy and also successfully reduce the rate of anastomotic leakage.
