Objective: Fetal monitoring is extremely important in perinatal care. Analysis of cardiotocogragh(CTG) can suppose if the fetus is lack of oxygen, distressed, acidosis, etc. in order to take measures timely. Methods: We have designed Meticare analysis software package to analyze 867 pieces of CTG data, and researched the relationship between short term variation (STV) and basal heart rate(BHR) by statistics, and short time monitoring analysis based on STV. Results: The amplitude of fetal heart rate curve variation(long term variation) tended to decrease when BHR increasing, with the negative correlation and regression equation STV = 9.866-0.02×BHR. Positive correlation exists between 5 and 10 mimute-STV, with the regression equation STV_(10min)=2.861-0.596×STV_(5min).Conclusion: STV calculated by 5 minutes CTG data can forecast the one by 10 minutes data as a reference demanded by Dawes & Redman criterion. If fetal doppler contains STV analysis function, out-patient fetal heart auscultation will be more significant. After 30 weeks pregnancy, with the STV decreasing, fetal distress, asphyxia, low birth weight, and even mortality increasing. BHR increasing should cause attention that STV might decrease, when monitoring with no analysis functional devices or fetal dopplars.

The effect of pH on the extracellularpolysaccharide synthesis by Aureobasidium pullulans was studied by addding CaCO3and HCI. Cultivated in P2 liquid medium for 24h,pH dropped to 3. 6 because of strongly producing acid. Under this low pH environment, further fermentation for 120h,only 5. 9g/L of polysacharide was obtained. When grown in MP2 medium contaning0. 5 % CaCOs,the pH was kept above 5.0 during 144 hours,production of polysaccharide increased to 31g/L. The detailed information of effects of controlled pH on polysaccharide production showed an optimal pH value 5. 0 must be maintained through the fermentative period.

Objective To investigate the effect of the peritoneal lymphatic stomata on intra-abdominal infection and the regulatory mechanism of angiotensin Ⅱ receptor specific inhibitor PD123319 on peritoneal lymphatic stomata.Methods The experimental study was adopted.Forty rats were divided into the control group,sham operation group,intra-abdominal infection group and intra-abdominal infection drug intervention group by the random number table,every group had 10 rats.The classic appendix perforation (CLP) intraabdominal infection model was established in the abdominal infection group.After establishing the model of abdominal infection,PD123319 solution was injected intraperitoneally immediately (0.2 g/kg) in the abdominal infection drug intervention group.Abdominal cavity of the rats in the sham operation group was opened,and then was shut after flipping the intestine.The rats in the control group,sham operation group and intra-abdominal infection group were treated with intraperitoneal injection of 1ml stroke-physiological saline solution.After 2 hours,the rats were sacrificed,and peritoneal tissue was taken for the following tests.(1) The aperture size and distribution density of peritoneal lymphatic stomata were observed by scanning electron microscope (SEM).(2) The nitric oxide (NO) concentration in the peritoneal tissues was detected using nitric oxide nitric acid reduction method.(3) The expressions of endothelial nitric oxide synthase (eNOS) and Phospho-eNOS (P-eNOS) were detected by the Western blot.(4) The intracellular Ca2+ concentration were detect by flow cytometry.Measurement data with normal distribution were presented as-x ± s.The comparison among groups was analyzed using the ANOVA and pairwise comparison was analyzed by the LSD test.Results (1) The aperture size and distribution density of the peritoneal lymphatic stomata in the control group,sham operation group,intra-abdominal infection group and intra-abdominal infection drug intervention group were respectively (2.3 ± 0.4) μm,(2.5 ± 0.5)μm,(4.7 ±0.5)pm,(3.8 ±0.5)pm and (2.0 ±0.8) × 108/m2,(2.1 ±0.7) × 108/m2,(6.2 ± 1.3) × 108/m2,(4.6 ± 1.4) × 108/m2,with statistically significant differences among the 4 groups (F =98.130,56.780,P < 0.05).There were statistically significant differences in the aperture size and distribution density of the peritoneal lymphatic stomata between the intra-abdominal infection group and control group or intra-abdominal infection drug intervention group (t =11.586,8.573,3.854,3.098,P < 0.05) and no statistically significant differences between the control group and sham operation group (t =1.281,0.514,P >0.05).(2) The concentrations of NO in the peritoneal tissues in the control group,sham operation group,intra-abdominal infection group and intra-abdominal infection drug intervention group were respectively (0.380 ± 0.024) μmol/gprot,(0.450 ±0.020) μmol/gprot,(1.253 ±0.033) μmol/gprot and (0.579 ±0.035) μmol/gprot,with a statistically significant difference among the 4 groups (F =52.725,P < 0.05).There were statistically significant differences in the concentration of NO between the intra-abdominal infection group and control group or intra-abdominal infection drug intervention group (t =10.536,67.798,P < 0.05) and no statistically significant difference in the concentration of NO between the control group and sham operation group (t =2.007,P > 0.05).(3) The results of Western blot showed that the expressions of eNOS and P-eNOS in the control group,sham operation group,intra-abdominal infection group and intra-abdominal infection drug intervention group were respectively (0.591 ± 0.028)U/mg,(0.603 ± 0.007) U/mg,(0.615 ± 0.027) U/mg,(0.626 ±0.026) U/mg and (0.578 ±0.003)U/mg,(0.603 ± 0.071) U/mg,(0.773 ± 0.033) U/mg,(0.710 ± 0.012) U/mg,with no statistically significant difference in the expression of eNOS among the 4 groups (F =0.902,P > 0.05) and with a statistically significant difference in the expression of P-eNOS among the 4 groups (F =205.062,P < 0.05).There were statistically significant differences in the expression of P-eNOS between the control group and sham operation group or intra-abdominal infection group (t =7.678,13.322,P < 0.05) and between the intra-abdominal infection group and intraabdominal infection drug intervention group (t =4.035,P <0.05).(4) The results of flow cytometry showed that Ca2+ concentration in the control group,sham operation group,intra-abdominal infection group and intraabdominal infection drug intervention group were respectively 82.200% ± 0.060%,81.730% ± 0.052%,21.980% ± 0.010%,29.500% ± 0.004%,showing a statistically significant difference between the 4 groups (F =21 271.030,P < 0.05).There were statistically significant differences in the Ca2+ concentration between the intra-abdominal infection group and control group (t =164.750,P < 0.05) and between the intra-abdominal infection group and intra-abdominal infection drug intervention group (t =21.338,P < 0.05),and no statistically significant difference between the control group and sham operation group (t =1.861,P > 0.05).Conclusion The intra-abdominal infection could increase aperture size and distribution density of peritoneal lymphatic stomata,and PD123319 may be through inhibiting the activation of NO synthase to decrease the concentration of NO,enhance the concentration of Ca2+ in peritoneal mesothelial cells and reduce the opening of peritoneal lymphatic stomata.

Objective To make a comparison of transthoracic echocardiography (TTE) and cardiac multi-slice spiral computed tomography (MSCT) in the diagnosis of partial anomalous pulmonary venous connection (PAPVC) in children.Methods One hundred and one patients admitted from February 2008 to April 2014 in Guangdong General Hospital primarily diagnosed with PAPVC with or without other congenital heart diseases were analyzed retrospectively,all the cases underwent routine TTE,which 74 cases underwent cardiac MSCT examination,and the TEE and cardiac MSCT diagnosis results were compared with final surgical findings,then the TTE and cardiac MSCT diagnosis accuracy was calculated.SPSS 13.0 software was used to analyze the data.Results All the patients underwent TTE examination,meanwhile,74 cases received cardiac MSCT examination.Ninety-three cases were confirmed by surgical findings,while 8 cases were misdiagnosed with PAPVC.Sixty-eight cases diagnosed by TTE coincided with surgical findings,and the diagnosis accuracy was 73.12% (68/93 cases);65 cases diagnosed by cardiac MSCT coincided with surgical findings,and the diagnosis accuracy was 94.20% (65/69 cases).Among the patients who received both TTE and cardiac MSCT examinations,66 cases were confirmed through final surgical operation,2 cases were mis-diagnosis,so the diagnosis accuracy was 97.06% (66/68 cases).Conclusions In terms of the diagnosis accuracy of PAPVC,cardial MSCT examination is superior to TTE,as almost all of the cases could be diagnosed by TTE combined with cardial MSCT.In consideration of the acoustics window of children,apart from the conventional parasternal approach of detecting pulmonary veins,the importance of suprasternal and subcostal views should also be attached.
