ObjectiveTo observe the effect of monosialo gangliosides-1 (GM-1) and Radix salviae miltiorrhizae (RSM) on neonatal hyposemic ischemic encephalopathy (HIE).Methods62 cases of HIE were randomly divided into treatment group and control group, and both groups received conventional therapy. Injection of RSM and GM-1 were added into the treatment group in 7～10 days therapy. ResultsHigh curative effect, average curative effect and total curative effect in the treatment group of 31 cases were 80.6%, 16.1% and 96.8%, while that in control group of 31 cases were 32.3%, 51.6% and 83.9% respectively. There was significant difference in the high curative effect and total effect between the two groups (P<0.05). ConclusionThe treatment combined with RSM and GM-1 can enhance the curative effect on HIE without any side effect.

Objective To analysis the therapeutic effect of microsurgery through single-nostril transsphenoidal approach on pituitary adenomas and to study the surgical skill and postoperative complications about microsurgery for pituitary adenomas.Methods The clinical manifestations,pathological type, removal percentage,postoperative complications and follow-up data of 241 cases with pituitary ademoma by microsurgery through single-nostril transsphenoidal approach were analysed retrospectively.Results 171(7 1%)cases were achieved total tumor removal,28(11.6%)cases were achieved subtotal tumor removal,26(10.7%)cases were achieved most tumor removal and 16(6.6%)cases were achieved partial tumor removal.Most of patients achieved better results,however there were 38(15.8%)eases with diabetes insipidus,12(4.9%)cases with transient worse sight,4(1.6%)cases with cerebrospinal fluid leakage,2(0.8%)cases with oculomotor paralysis,and no death.The postoperative complications were cured and outcome was considered as good.The follow-up period was 1-36 months in 241 patients and the clinical symptoms were improved by different degrees.Conclusion Pituitary adenomas can be treated by microsurgery through single-nostril transsphenoidal approach due to the time of operation shorten,the postoperative complications.

Objective To investigate the relationship between the grade of gliomas and the status of adjacent fiber tract with DTL Methods MRI and DTI were performed in 24 patients with histologically confirmed brain gliomas.Regions of interest were placed in the white matter adjacent to the tumor with the lowest FA(Faa) and in the white matter of the contralateral hemisphere(Fac).The values of Faa and Fac were measured.In the regions of the same slice, the values of ADCa and ADCc were measured. Relative fractional anisotropy ratios (rFA) and relative apparent diffusion coefficient ratios (rADC) were also calculated.The status of fiber tracts adjacent to the gliomas were characterized as displacement, infiltration or disruption.Fiber tracking using the Fiber Assignment by Continuous Tracking (FACT) method was performed to investigate the integrity of white matter tracts in the surrounding border zone of the gliomas.The correlation of rFA, rADC, the state of adjacent fiber tracts, and the grade of gliomas were analyzed statistically by using independent sample t test and tendency X2 test.Results Eleven of the 24 tumors were demonstrated as low grade gliomas (WHO grade Ⅰ-Ⅱ) and 13 were high grade giiomas (WHO grade Ⅲ-Ⅳ).The average rFA and rADC of the low grade gliomas were 0.65±0.19 and 1.43 ± 0.50 respectively.Most of fiber tracts in the periphery of the low grade gliomas were displaced or infiltrated.The average rFA and rADC of the high grade gliomas were 1.51 ± 0.39 and 1.70 ±0.27 respectively.Most of fiber tracts in the periphery of the high grade gliomas were infiltrated or disrupted.Significant difference was found for rFA (t =8.504,P =0.000) and but not for rADC(t = - 1.435 ,P =0.165) between low grade and high grade gliomas.Significant difference existed between the state of fiber tracts adjacent to ghomas and low and high-grade(X2 =5.882 ,P =0.015).Conclusions The malignancy of gliomas influences the state of fiber tracts in the vicinity of tumors, rFA can serve as a reference for distinguishment of high-grade and low-grade gliomas.DTI can depict the localization of gliomas and the adjacent fiber tracts.The state of fiber tracts can also be identified by DTI.It is helpful for the therapeutic plan of the tumors.

Objective To investigate the application of neurophysiological monitoring and microsurgi-eal technique in acoustic neurinoma resection, exploring the significance of neurophysiological monitoring in facial and auditory nerve reservation of acoustic neuronma microsurgery. Methods Accompanied with EMG and BAEP nerve monitoring, 113 patients harboring acoustic neuroma were treated surgically by the subocipi-tal retrosigmoid approach for reserving facial and auditory nerve. The facial nerve was stimulated to evaluate its function during late-operation. Postoperative facial and auditory nerve function were valuated in all the postop-erative following up. Results All of them were treated microsurgically via the suboccipitai retrosigmoid ap-proach. Total tumors resection was achieved in 102 cases (90.3%), subtotal resection in 6 cases(5.3%) and partial resection in 5 case (4.4%). The facial nerve was preserved anatomically in 98 cases (86.7%), the functional valuation of facial nerve according to the House-Brakman (H-B) postoperatively: 86 cases (76.1%) in class Ⅰ -Ⅱ , 12 cases(lO.6%) in class Ⅲ-Ⅳ and 15 cases (13.3%) in class Ⅴ-Ⅵ. The acoustic nerve was preserved anatomically in 40 cases (35.4%). It denoted the good function of facial nerve responsing sensi-tively to electrostimulation ≤ 4mA at the end of operation. Conclusion Assisted with the intraoperative electrophysiological monitoring techniques, it would be greatly facilitate the preservation of facial and auditory nerve in acoustic neuroma resection. Simultaneously, it would valuate the functional convalescence by late-op-erative electrostimulation in the postoperation.

Objective To assess the efficacy and side effects of intravesical instillation of BCG after transurethral resection of the bladder tumor (TURBT) in non-muscle invasive bladder cancer (NMIBC) patients.Methods The clinical data of patients treated with BCG 120 mg per course induced perfusion or more after TURBT from December 2013 to October 2016 in 18 hospitals of northeast China region,were analyzed retrospectively.The first part,data of 106 patients with moderate,high-risk NMIBC were collected.A total of 83 patients were male,while the other 23 patients were female.The average age was 66.7 years old.The clinical staging were T1 in 86(81.1％) cases,Ta in 20(18.9％) cases and carcinoma in situ in 6 (5.7％) patients.Intravesical instillation of BCG was executed after transurethral resection of the bladder tumor.The incidence rate of recurrence and progression during more than 6 months' follow-up time were observed.Multivariate analyses were done by using logistic analysis and Cox proportional hazards regression model with Kaplan-Meier method.The second part,treatment compliance of 276 patients with bladder cancer,including moderate/high-risk NMIBC in 263 cases,moderate/high-risk NMIBC followed with renal pelvis/ureteral carcinoma in 8 cases were and moderate/high-risk NMIBC with renal pelvis/ureteral carcinoma in 5 cases who treated with BCG after the surgeries,were observed.Patients consisted of 211 males and 65 females with average age of 68.3 years.Results With a median follow-up of 12 months,9 (8.5％) patients experienced tumor recurrence and 2 (1.9％) patients were found progression in the first part.The one-year cancer free recurrence rate of the patients was 91.5％.Statistically significant prognostic factors for recurrence identified by multivariable analyses were prior recurrence of the tumors (OR =3.214,95％CI0.804-12.845,P =0.099).In the second port,an incidence rate of adverse effects was 64.1％ (177/276).The Ⅲ/Ⅳ degree complications were occurred in 11 patients and satisfactory outcomes achieved with active treatment.A total of 36 patients withdrawal with the major causes were recurrence and progression of bladder tumor in 12 cases (4.4 ％),9 cases (3.3 ％) with economic reasons and 11 cases (4.0％) with serious complications.Conclusions NMIBC patients treated with intravesical BCG therapy have approving cancer free recurrence rates and acceptable adverse effects.Prior recurrence may be prognostic factor of recurrence after intravesical BCG therapy.

BACKGROUNDAmplatz dilation and balloon dilation are different methods in creating the accesses during percutaneous nephrolithotomy (PCNL). The aim of this study was to review the surgical experiences of managing staghorn calculi by Amplatz dilation and balloon dilation for 3 years.

METHODSWe retrospectively analyzed clinical data from 125 patients (129 kidneys) with staghorn kidney stones who underwent PCNL from January 2010 to December 2012, of whom 60 patients underwent Amplatz dilation (AD group) and 65 underwent balloon dilation (BD group) during PCNL.

RESULTSThe AD and BD groups were similar in age, male-female ratio, stone burden, stone type, hydronephrosis, and proportion of patients who had undergone extracorporeal lithotripsy. However, these two groups showed significant differences in terms of duration of percutaneous access (15.1 ± 3.6) minutes vs. (10.0 ± 3.3) minutes, one-attempt success rate of dilation via a single access 88.9% (72/81) vs. 97.8% (91/93), hemoglobin drop after surgery (3.5 ± 0.9) g/dl vs. (1.7 ± 0.9) g/dl, number of cases requiring intraoperative and postoperative blood transfusion 27.9% (n = 17) vs. 13.2% (n = 9), changes of central venous pressure before and after surgery (2.3 ± 1.2) cmH2O vs. (1.2 ± 0.7) cmH2O, number of patients who experienced postoperative fever >37.5°C 21 (34.4%) vs. 13 (19.1%) (all P < 0.05). No injury of adjacent organs, including pleura, liver, spleen, or bowel, was noted in patients.

CONCLUSIONSDuring ultrasound-guided PCNL for staghorn stones, balloon dilation and Amplatz dilation are all effective and safe. Compared with Amplatz dilation, balloon dilation is a better choice, as it has a higher access creation success rate, shorter access creation time less blood loss, and lower proportions of circulatory overload and postoperative fever.
