Objective To investigate the safety and efficiency of large-dose alcohol sclerotherapy in treating simple hepatic cyst. Methods Patients with hepatic cyst were divided into two groups. One group with 49 patients was treated with small-dose (<80 ml) absolute alcohol instillation. The other one with 32 patients was treated with large-dose (≥80 ml) absolute alcohol instillation. Blood alcohol concentration (BAC) was recorded right after and 30 rain, 1 h,2 h,3 h after the treatment. Diameter of cyst as a parameter of efficiency was recorded and compared between two groups during 1 year follow-up visit. Results Large-dose group was significantly more efficient in treating hepatic cyst than small-dose group. All BAC records were within the safe range and below the legal limit after drinking. BAC reached its peak 30 minutes after the treatment began and then decreased gradually. A significant correlation was found between BAC and the alcohol dosage. Conclusions Ultrasound-guided sclerotherapy with repeated large-dose absolute alcohol instillation is a safe and efficient treatment for simple hepatic cyst from the perspective of BAC.

Objective To study the relationship between essential hypertension(EH)with serum homocysteine(HCY),uroten-sinⅡ(UⅡ),angiotensin converting enzyme(ACE)and N-terminal pro-brain natriuretic peptide(NT-proBNP).Methods By collec-ting the clinical cases,UⅡwas determined by ELISA and HCY,ACE and NT-proBNP were simultaneously detected by ELISA.The detection results were analyzed and compared between the patients with essential hypertension(EH group)and the healthy con-trols.Results The levels of serum HCY,UⅡ,ACE and NT-proBNP in the EH group were significantly increased compared with the healthy control group;the area under curve (AUC)of serum HCY,UⅡ,ACE and NT-proBNP in the ROC curve in the EH group were 0.93,0.765,0.792 and 0.972 respectively,which showed clinical diagnostic significance.Conclusion The levels of HCY,UⅡ,ACE and NT-proBNP are highly expressed in EH and have significant differences compared with the healthy popula-tion,which has the diagnostic value to EH.

Objective To investigate effects of different concentrations of dexmedetomidine on onset time and clinical time-effect of rocuronium in the processes of the total intravenous anesthesia.Methods Sixty patients with elective anesthesia breast modified radical mastectomy,aged 26 to 55 years,were randomly divided into four groups of 15 patients.Group A (control group):uniform within 10 min before induction of anesthesia saline infusion (NS ; 0.25 ml/kg) ; group B:dexmedetomidine given initial dose 0.3 μg/kg uniform within 10 min before induction of anesthesia infusion finished,anesthesia period 0.3 μg/(g · h) continuous infusion until the end of surgery; group C:dexmedetomidine given initial dose 0.6 μg/kg uniform within 10 min before anesthesia infusion finished,during anesthesia with continuous infusion 0.6 μg/'(kg · h) until the end of surgery ; and group D:dexmedetomidine given initial dose 1 μg/kg uniform within 10 min before anesthesia infusion finished,during anesthesia to 1 μg/(kg · h) continuous infusion to the end of surgery.Patients after the burglary were under multi-monitor vital signs monitoring blood pressure (BP),heart rate (HR),oxygen saturation (SPO2),electrocardiogram (ECG),and after intubation monitoring end-tidal carbon dioxide (EtCO2),recording time T0 and T25.Results No significant difference was found at the T0 time in each group.However,the T25 time (48 ± 6) min in group C and (51 ±6) min in group D was significant longer than that (40 ±6)min in group A (P ＜0.05).The mean artery pressure(MAP) of group C and D [(88.76 ± 7.06)mmHg,(87.89 ± 6.95)mmHg] were significantly lower than group A after dexmedetomidine infusion 5 min later(P ＜ 0.05); The HR of groups B and C [(60.80 ± 7.11)bpm,(63.31 ± 5.78)bpm] were significantly lower than group A before induction (P ＜ 0.05).The HR of group D was significantly lower than group A before induction and after infusion 5 and 30 min later[(66.40 ± 9.49) bpm,(60.52 ± 7.45) bpm,(61.32 ± 7.11) bpm,P ＜ 0.05].Conclusions Under the status of total intravenous anesthesia,different concentrations of dexmedetomidine did not affect the onset time of rocuronium,but dexmedetomidine given up to a certain concentration could enhance the clinical time-effect of rocuronium.

Objective To compare the effects of median nerve electrical stimulation on coma patients after traumatic brain injury with different settings. Methods From 2013 to 2015, 161 patients with traumatic brain injury were randomly divided into control group (n=40), experimental group 1 (n=41), experimental group 2 (n=39) and experimental group 3 (n=41).
