We studied the immunoreactive Beta-endorphin (ir-?-Ep) plasma levels inresponse to an oral glucose tolerance test in 7 children with simple obesity and 7 childrenof normal weight. It was shown that the levels of ir-?-Ep and insulin were significantlyhigher in the obese children as compared to controls during oral glucose tolerance test,which reached a peak at 60 minutes. The result supports the concept of a possible linkbetween Beta-endorphin and glucose homeostasis.

Results of experiments such as ammonia steaming test in mice and citric acid test in guinea pigs, phenol red secretion test in mice and capillary expectorant test in rats, in-vivo and in-vitro antiasthmatic tests in guinea pigs proved that Tankeqing capsule had good antitussive, expectorant and antiasthmatic effects and a significant time-effect relationship was showed. The antitussive effect and expectorant effect arrived to the peak in 1-6h after oral administration, and the antiashmatic effect in about 1h.

Objective To measure the levels of neutrophil elastase (NE),citric acid and pH in prostatic fluid of patients with prostatitis type Ⅲ.Methods Fifty two patients with prostatitis type ⅢA,98 patients with prostatitis type Ⅲ B and 105 health subjects were enrolled in the study.The levels of NE,citric acid and pH in prostatic fluid were measured ; the expressed prostatic secretion (EPS) routine and bacterial culture were examined,and National Institutes of Health (NIH)-chronic prostatitis symptom index (NIH-CPSI) was evaluated.The data were analyzed by independent samples t-test.Results WBC count,NE and citric acid concentrations,pH in ⅢA group were (17.9 ±5.4)/HP,(898 ±704) μg/L and (14.5 ± 1.7) ng/L,7.60 ±0.43,respectively; those in ⅢB group were (3.9 ±2.2)/HP,(93 ±76) μg/L and (21.9 ±3.8) ng/L,6.71 ±0.25,respectively; those in control group were (3.6 ±2.2)/HP,(86 ±57) μg/L and (22.5 ± 3.9)ng/L,6.48 ± 0.51,respectively.There were significant differences in NE and citrate concentrations,pH value in EPS between Ⅲ A and Ⅲ B patients (t =8.22,16.64 and 13.88,all P ＜0.05),but no difference in NIH-CPSI (t =1.90,P 8 0.05).There were significant differences in WBC count,NE and citric acid concentrations,pH in EPS,NIH-CPSI score between Ⅲ A and control groups (t =18.92,8.47,26.53,18.37 and 32.47,all P ＜ 0.05).There were no differences in WBC count,NE and citric acid concentration and pH value in EPS between Ⅲ B group and control group (t =1.38,1.55,1.02 and 1.21,respectively,all P 80.05),but there was significant difference in NIH-CPSI score between two groups (t =49.46,P ＜ 0.05).In EPS,NE concentration and WBC count were positively correlated with NIH-CPSI (r =0.819 and 0.698,respectively,all P ＜0.01),and citric acid was negatively correlated (r =-0.625,P ＜ 0.01) ; citrate was negatively correlated with WBC count,CPSI and pH value (r =-0.728,-0.644 and-0.817,all P ＜ 0.01).Conclusions The results indicate that the measurements of NE,citric acid and pH in EPS are of significant clinical value in patients with prostatitis type ⅢA and Ⅲ B.

Objective To determine the influencing factors on prognosis of neonatal necrotizing enterocolitis (NEC) in premature infants with a gestational age of 28-32 weeks.Methods Forty-six cases of NEC (Bell stage Ⅱ or Ⅲ) with a gestational age of 28-32 weeks admitted to Bayi Children's Hospital from January,2009 to January,2013 were analyzed retrospectively.Twenty-nine cases were assigned to the cured group and 17 cases were assigned to the poor prognosis group according to prognosis.General conditions,laboratory results,treatment and complications in the two groups were analyzed.The Chi-square test,Fisher's exact test and univariate analysis of variance were used for statistical analysis.Results There were no statistically significant differences regarding gender,average birth weight and mean age of onset between the two groups [average birth weight (1 410.52±281.59) g vs (1 266.47±280.32) g and mean age of onset:(20.79± 10.61) d vs (16.71 ±9.41) d for the cured group versus the poor prognosis group,respectively].There were no difference in changes in white blood cells and platelets between the two groups.There were six cases of positive blood culture in the poor prognosis group and none in the cured group.There were no differences in procedures such as blood transfusion and ibuprofen administration [41.4％ (12/29) vs 11/17 and 6.9％ (2/29) vs 5/17,both P＞0.05,in the cured group versus the poor prognosis group,respectively].There were significant differences in the use of Bifidobacterium between the two groups [69.0％ (20/29) vs 5/17,x2=6.758,P=0.009].Fourteen cases in the cured group and 10 cases in the poor prognosis group underwent surgery,and all 10 cases in the poor prognosis group died.Seven cases underwent repeated surgery,one infant in the cured group and six infants in the poor prognosis group and a significant difference was observed (Fisher's exact,P=0.007).A statistically significant difference in granulocyte colony-stimulating factor (G-CSF) treatment was observed between the two groups,where 15 cases in the cured group and three cases in the poor prognosis group were treated with G-CSF (x2=5.225,P＜0.05).Statistically significant differences in septicemia,patent ductus arteriosus,gastrointestinal perforation,multiple organ failure (MOF),disseminated intravascular coagulopathy (DIC) and septic shock were observed between the two groups [septicemia:44.8％ (13/29) vs 15/17,x2=8.478; patent ductus arteriosus:17.2％ (5/29) vs 9/17,x2=6.451; gastrointestinal perforation:3.4％ (1/29) vs 6/17; MOF:0.0％ (0/29) vs 5/17; DIC:0.0％ (0/29) vs 3/17; septic shock:3.4％ (1/29) vs 6/17,all P＜0.05 in the cured group versus the poor prognosis group,respectively).Conclusions Oral intestinal microbial preparations before the onset of NEC and G-CSF therapy after the onset of NEC may be protective factors in improving the prognosis of NEC,while patent ductus arteriosus,septicemia,gastrointestinal perforation,MOF,DIC and septic shock are risk factors.Emphasis should be placed on the administration of intestinal microbial agents,prevention of infection and treatment of complications.

Objective To analyze the effect of circulatory failure on ventilation therapy of respiratory failure after resuscitation in neonates with severe asphyxia. Methods Three hundred and eighty-two neonates with mechanical ventilation following severe asphyxia were retrospectively analyzed. Two groups were divided according to the efficacy of mechanical ventilation: effective and noneffective. Results The non-effective rate was 24.1% at 1 hour after ventilation (19.4% in full term babies,34.5% in preterm babies). The degree of asphyxia in noneffective group was significantly more severe than the effective group. The incidence of persistent pulmonary hypertension of the newborns(PPHN),exsanguine shock,cardiogenic shock,DIC and cardiac failure was 84.3%、51.0%、80 4%、49.0% and 54.9% respectively in term babies,while the incidence of exsanguine shock,cardiogenic shock,DIC and cardiac failure was 65.9%、68.3%、75.0% and 58.5% respectively in preterms babies. All of them were significantly higher than the effective group. After treatment of the circulation problems,the blood gas turned to normal in 94.1% term babies and 92.7% of preterms. No difference was shown in the recovery rate in both groups. Conclusion The circulatory failure is a main cause of non-effective mechanical ventilation in asphyxia neonates. To correct the pathophysiologic changes of the circulation in time can effectively improve the prognosis.

Objective To investigate the expressions of VEGF and Ang-1 in neonatal rats with hyperoxia-induced BPD and its effects on lung development. Methods 48 SD neonatal rats (2 or 3 days old) were randomly divided into two group and raised under hyperoxia or air for 1, 3 and 7 days, respectively. Real-time RT-PCR and Western blot were used to determine the level VEGF and Ang-1 mRNAs and proteins in lung tissues of the two groups. HE staining was used to observe the changes of lung morphology. Results The levels of VEGF and Ang-1 mRNAs in the lung on the 7th day in the control group were 0.722 ± 0.372 and 0.828 ± 0.462, respectively, and those in hyperoxia group were 0.239 ± 0.293 and 0.327 ± 0.184 , respectively. The levels of VEGF and Ang-1 proteins on the 7th day in the control group were 0.632 ± 0.289 and 0.573 ± 0.436, respectively, and those in hyperoxia group were 0.358 ± 0.128 and 0.204 ± 0.068 , respectively. Comparing to the control group , the levels of VEGF and Ang-1 mRNAs and proteins on the 7th days significantly decreased in the hyperoxia groups (P<0.05). The lung tissues of the hyperoxia group display dysplastic features with , alveolar simplification , reduced alveolar numbers and retardation on microvascular development. Conclusion VEGF and Ang-1, functioning as an important regulators for pulmonary vascular development , are involved in the pathogenesis of BPD and the lung development.
