Objective To analyze the predictive factors of fever after percutaneous renal stone surgery,and to provide reference for clinical treatment.Methods A total of 147 patients underwent percutaneous nephrolithotomy in after operation was chosen in the Department of Urology in our hospital from January 2014 to January 2016.According to the existence of fever,patients were divided into fever (n =25,heating rate 17.0%) and control (n =122) groups.Preoperative information were collected,including age,gender,preoperative serum creatinine,stone size and shape,the involvement of calyceal number,water,urine culture results,operative time,blood loss,intraoperative perfusion volume,pyonephrosis,puncture channel length,hospitalization time and other information including intraoperative,postoperative information including fever,and postoperative renal fistula complications if there is information.SPSS 18.0 was used for statistical analysis.Results The fever group stone surface area,CT value affected calyx number,stone shape,stone properties,the involvement of calyceal number,degree of hydronephrosis,operative time,intraoperative blood loss,intraoperative perfusion,hospitalization time,and renal fistula complication rates were higher than the control group (P < 0.05).There were no significant differences between two groups (P >0.05).The results of Logistic regression analysis found that the stone surface area (OR =5.19),stone,stone shape (OR =7.86) properties (OR =3.87),operation time (OR =5.68),intraoperative perfusion (OR =5.24),and renal fistula complications (OR =2.65) for the influence factors of fever.Conclusions The stone surface area is large,stone nature infection stones,stone shape for staghorn calculi,longer operation time,and intraoperative perfusion of large renal fistula complications were more prone to postoperative fever in postoperative.

The purpose of this study was to compare the effect of sodium fluoride(NaF) varnish and potassium iodide(KI) on remineralization efficacy of silver diamine fluoride(SDF) by measuring microhardness and evaluating surface morphology by scanning electron microscope(SEM).
Artificial caries lesions were induced on extracted primary molars and vickers microhardness was measured. Specimens were randomly separated into 4 groups for treatment. The specimens in group I were treated with SDF, group II with NaF varnish after SDF, group III with KI after SDF and group IV with distilled water. After 8 days of pH cycling, vickers microhardness was measured and difference before and after treatment was calculated. For SEM, 2 samples were evaluated respectively after enamel polishing, lesion formation and after pH cycling.
Group III showed highest increase in microhardness. Group I showed higher increase in microhardness than Group II but without statistical difference. Group IV showed lowest increase in microhardness value among 4 groups.
On SEM image, group I, II and III showed smoother and less irregular surface compared to group IV. Amorphous crystal pellicles were observed in group III.
In conclusion, SDF, SDF and NaF, SDF and KI groups showed smoother surface and increase in microhardness suggesting the possibility that remineralization effect might take place in oral conditions. In addition, in limited conditions of this study, applying NaF varnish after SDF did not increase the remineralization efficacy of SDF while KI significantly increased the remineralization efficacy of SDF. However, additional study considering various conditions that might affect demineralization and remineralization in clinical situations need to be conducted.

BACKGROUND: Carbetocin is a long-acting synthetic analogue of oxytocin that is used to prevent postpartum hemorrhage. Cardiovascular effects of oxytocin include tachycardia and hypotension. We investigated hemodynamic changes induced by carbetocin during spinal anesthesia. METHODS: Carbetocin 100 microg was infused over 5 min in 40 women undergoing cesarean delivery. Hemodynamic parameters were measured noninvasively using the Finometer(R) device. The hemodynamic values were analyzed using multivariate analysis of variance followed by Bonferroni test for multiple comparisons. RESULTS: Statistically significant hemodynamic effects were seen with a maximal effect at about 75 seconds after infusion start compared with those of baseline: Mean arterial pressure (MAP) decreased 21.6 +/- 8.8 mmHg, systemic vascular resistance (SVR) decreased 28.6 +/- 11.1% and heart rate (HR) increased 15.3 +/- 7.9 beats/min. Following the maximal effect, MAP and SVR remained almost constant at this decreased level until the end of study period. However, HR was slowly recovered after the peak, approaching the baseline value. CONCLUSIONS: We observed that the maximal hemodynamic changes were occurred at about 75 seconds after administration of carbetocin. Therefore, careful observation is required during this early period.

Objective To explore the feasibility of tubeless 2 μm laser vaporesection in treating pediatric ureter cysts by ureteroscopy.MethodsClinical data of 33 ureter cysts patients who received tubeless 2 μm laser vaporesections by ureteroscopy were reviewed. The median age of patients was 4 years with a range from 1 to 7 years. The operations were carried out by RevoLix 2 μm laser through ureteroscopy without ureter stents and catheters indwelling.ResultsAll operations were successfully performed. And no serious complications occurred after the operations.ConclusionsTubeless transurethral 2 μm laser treatment by ureteroscopy was a superior micro-invasive surgery method for pediatrics with ureter cysts, with advantages of little blood loss, high safety, convenient operation and infrequent complications.

OBJECTIVES: Local gyrification reflects the early neural development of cortical connectivity, and is regarded as a potential neural endophenotype in psychiatric disorders. Several studies have suggested altered local gyrification in patients with bipolar I disorder (BD-I). The purpose of the present study was to investigate the alterations in the cortical gyrification of whole brain cortices in patients with BD-I. METHODS: Twenty-two patients with BD-I and age and sex-matched 22 healthy controls (HC) were included in this study. All participants underwent T1-weighted structural magnetic resonance imaging (MRI). The local gyrification index (LGI) of 66 cortical regions were analyzed using the FreeSurfer (Athinoula A. Martinos Center for Biomedical Imaging). One-way analysis of covariance (ANCOVA) was used to analyze the difference of LGI values between two groups adjusting for age and sex as covariates. RESULTS: The patients with BD-I showed significant hypogyria in the left pars opercularis (uncorrected-p = 0.049), the left rostral anterior cingulate gyrus (uncorrected-p = 0.012), the left caudal anterior cingulate gyrus (uncorrected-p = 0.033). However, these findings were not significant after applying the multiple comparison correction. Severity or duration of illness were not significantly correlated with LGI in the patients with BD-I. CONCLUSIONS: Our results of lower LGI in the anterior cingulate cortex and the ventrolateral prefrontal cortex in the BD-I group implicate that altered cortical gyrification in neural circuits involved in emotion-processing may contribute to pathophysiology of BD-I.
