Objective To discuss the safety and clinical effect of fine needle single-step centesis in percutaneous endoscopic nephrolithotomy for renal staghorn calculi. Methods Percutaneous endoscopic nephrolithotomy with fine needle single-step centesis was employed in 75 patients (single-step group) with renal staghorn calculi, and percutaneous endoscopic nephrolithotomy with two-step centesis was adopted in other 75 patients with renal staghorn calculi (two-step group). The clinical effect and the incidence of complications were compared between the two groups. Results The placement of drainage catheter was successfully accomplished in all 150 patients. In single-step group the operation time was 18-45 minutes with a mean of 36 minutes; the mean blood loss during the procedure was about 5 ml. After the treatment, massive bleeding occurred in 3 cases that needed blood transfusion, and residual stone was observed in 6 cases. In two-step group the operation time was 16-42 minutes with a mean of 34 minutes; the mean blood loss during the procedure was about 7 ml. After the treatment, massive bleeding occurred in 7 cases that needed blood transfusion; one of them had renal pseudoaneurysm and the bleeding was stopped after renal artery embolization treatment; and residual stone was observed in 7 cases. No procedure-related perirenal organ injury was seen in single-step group, while in two-step group pneumothorax (n=1) and injury of splenic flexure of colon (n=1)were found. Conclusion In performing percutaneous endoscopic nephrolithotomy, fine needle single-step centesis is more safe and effective than conventional two-step centesis.

Objective To study the effect of mesylate ropivacaine programmed intermittent epidural injection for labor analgesia. Method 100 cases of ASA I or II single cephalic term primiparae , randomly divided into epidural rules intermittent administration group (Group A) and continuous epidural infusion group (Group B), 50 cases of each group. Two groups were treated with 0.12%mesylate ropivacaine and 2 μg/mL fentanyl. The two groups were observed in different stage of labor , uterine contraction analgesic effect , mode of delivery , fetal distress and neonatal asphyxia. Result Compared with Group B, the VAS scores of women in Group A were decreased significantly and the difference was statistically significant (P < 0.05) after they had the labor analgesia 60min later, the mouth of the uterus opened to 5-6cm and all. There is no statistical significance in the mode of delivery and Apgar score. Conclusion Ropicacaine mesilate epidural programmed intermittent bolus are safe and effective for labor analgesia. Compared with continuous epidural infusion analgesia in labor , maternal satisfaction is higher and there is no significant adverse effects on mother and infant.

Objective Onto investigate the significance of the pleth variability index (PVI) in predicting hypotension after epidural anesthesia for cesarean delivery. Methods Sixity seven pregnant women, with ASAⅠ~Ⅱ, aged 19 ~ 34 years, were enrolled for elective cesarean delivery. SBP, BDP, MAP, HR, PI and PVI were measured at 5 min after the parturients arrived in the operation room. SBP, BDP, MAP and HR were measured every 3 min after epidural anesthesia. According to the change rate of SDP or MAP was higher than 30% or not, the parturients were divided into two groups (the hypotension group and the non-hypotension group). Results No significant differences were found in parturients'age, body height, weight, BMI, gestational weeks, SDP, DBP, MAP and HR before anesthesia between two groups. The PVI in the hypotension group was significantly higher than that in the non-hypotension group (P<0.05). A receiver operator characteristic curve analysis showed the area under curve was 0.888 when PVI was used for boundary value. When PVI over 17.35 was used as the occurrence of hypotension, the sensitivity of PVI was 0.727, and specificity was 0.895. Conclusion PVI can be used to predict the occurrence of hypotension after epidural anesthesia for cesarean delivery.

Objective To explore the clinical application value of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) in diagnosis and treatment of symptomatic patent ductus arteriosus (sPDA) in preterm infants. Methods A total of 107 preterm infants with gestational age of 28-32 weeks and birth weight less than 1500 g who were admitted to the neonatal intensive care unit from October 2013 to September 2014 were recruited. Plasma NT-proBNP were on 4th and 7th day after birth. The echocardiography examination was performed within 30 minutes after the blood was drawn. According to the echocardiography examination on 4th day after birth, the infants were divided into the patent ductus arteriosus (PDA) group (n?=?39) and the control group (n?=?68). According to whether there were signiifcant hemodynamics changes of ultrasonography and clinical symptoms, the PDA group were classiifed into the sPDA group (n?=?20) and the asymptomatic PDA group (asPDA, n?=?19). Then according to whether ibuprofen was taken, the sPDA group was further divided into treatment group (n?=?13) and non-treatment group (n?=?7). Results On the 4th day after birth, the level of plasma NT-proBNP in the sPDA group was signiifcantly higher than that in asPDA group, and the level of plasma NT-proBNP in asPDA group was signiifcantly higher than that in the control group (P??0.05). In the treatment group, the level of plasma NT-proBNP on the 7th day after birth was signiifcantly lower than that on the 4th day after birth (P??0.05). In PDA group, the level of plasma NT-proBNP on the 4th day after birth was positively correlated with ductus arteriosus (DA) diameter, ratio of the left atrium to aortic root diameter (LA/AO ratio) and transductal diameter-to-left pulmonary artery ratio (TDD/LPA) (r?=?0.498-0.670, respectively). The area under receiver operator characteristic (ROC) curve for prediction of sPDA by the plasma NT proBNP on the 4th day after birth was 0.969 (95%CI:0.938-1.000). When the NT-proBNP was 13964 pg/ml on the 4th day after birth, the sensitivity for diagnosis sPDA was 95%, the speciifcity was 95.4%. Conclusions The level of plasma NT-proBNP is signiifcantly higher in preterm infants with sPDA and is decreased after treatment. Plasma NT-proBNP on the 4th day after birth is a sensitive marker for predicting sPDA. Dynamic monitoring of plasma NT-proBNP has important clinical value in selection of the treatment strategy in preterm infants with PDA.

Objective To investigate the dynamic changes of soluble urokinase-type plasminogen activator receptor (suPAR) and its predictive value in late-onset sepsis in the newborn.Method To collect the data of neonates aged 7 days and older,who were diagonsed to have infections.They were admitted to neonatal intensive care unit of our Hospital from January 2014 to January 2015.The group of sepsis and nonseptic group were assigned according to the diagnostic criteria of sepsis,and a control group was selected without infection.Blood cultures were collected in patients on the first day when infection was identified and the serum suPAR and CRP were measured on the first day,fourth day and tenth day respectively.The controls were tested with suPAR and CRP when infection was excluded.The levels of blood suPAR and CRP in the three groups were compared and the receiver-operating characteristic curve was performed according to serum suPAR level of neonates with sepsis on the first day.Result A total of 65 infants with infections (40 were septic and 25 were non-septic) were enrolled in this study and 20 patients were selected as control group.There were significant differences in serum suPAR and CRP levels between the patients with and without infection (P ＜ 0.001).The level of suPAR in the survivors of the sepsis group was significantly decreased as time went by,and the difference was statistically significant on the 10th day compared with the 1 st day [9.3 (8.2,13.1) ng/ml vs.18.9 (14.8,24.7) ng/ml,P ＜ 0.05].The level of CRP increased first initially and then decreased with time,while the highest level was on the 4th day and the difference was statistically significant compared with the 10th day [19.0 （ 6.8,56.4) mg/L vs.6.4 (2.5,12.0) mg/L,P ＜ 0.05].The levels of serum suPAR and CRP in non-sepsis group were not significantly different (P ＞ 0.05).There were no deaths in the sepsis group and the non-septic group,but the levels of suPAR between survivals and deaths in the infection groups were statistically significant [15.4(10.6,21.6) ng/ml vs.22.6 (15.4,31.9) ng/ml,Z =-2.063,P =0.039].The area under the receiver-operating characteristic curve of serum suPAR was 0.955 (95％ CI 0.906 ～ 1.000,P ＜0.001),and the sensitivity was 90％ and the specificity was 100％ when the suPAR level was 10.9 ng/ml.Conclusion Early elevated serum suPAR levels were prominently related to the severity of neonatal late-onset sepsis.The level of first day suPAR has a high sensitivity and specificity in the prognosis of sepsis and can be helpful to predict the prognosis.
