ABSTRACT

Objective@#To evaluate the efficacy and safety of different positions external physical vibration lithecbole (EPVL) therapy for ureteral calculi related renal colic.@*Methods@#This study was a prospective multicenter randomized controlled trial. The inclusion criteria was that patients volunteered to participate in the trial and signed informed consent, patients’age ranged from 18-65 years old, ureteral calculi related with renal colic, stone diameter was less than 7 mm, patients were not treated with analgesia, antispasmodic drugs. The exclusion criteria was that combination of severe urinary tract infection, severe hydronephrosis, urinary malformation, severe hypertension, history of cerebrovascular disease, vital organ dysfunction, obesity (BMI>35 kg/m2), history of ureteral calculi exceeded 2 months, abnormal blood coagulation. Patients were randomized into observation group and control group using random number table method. The observation group and the control group were placed on the physical vibration stone arranging machine with head low foot high position and head high foot low position respectively. The inclination angle was 24°. The secondary vibrator vibrated for 6 minutes, then the patient took the prone position and opened the main, the secondary vibrator. The treatment is completed after 6 minutes of vibration. The analgesic effect, stone removal, follow-up effects and adverse reactions in the two groups was compared. We defined the pain relief rate as(VAS score before treatment-VAS score after treatment)/VAS score before treatment×100%.@*Results@#A total of 100 patients were included in the study, 50 in the observation group and 50 in the control group. There were no statistical difference in the age of the two groups [(41.8±11.7)years and (46.6±13.9 years)], gender distribution [37(male)/13(female) and 42(male)/ 8(female)], location of stones (in the observation group, 19 cases in upper ureter, 7 cases in the middle ureter and 24 cases in the lower ureter; in the control group, 12 cases in the upper ureter, 3 cases in the middle ureter, and 35 in the lower ureter), left and right distribution of stones [21(right)/ 29 (left) and 22 (right)/ 28(left)], long diameter of stones [(5.2±0.9)mm and(5.1±1.1)mm], VAS scores before treatment (7.5±1.4 and 7.6±1.5), and readmission rate [22%(11/50)With 18%(9/50)], 1 week stone removal rate [70%(35/50) and 64%(32/50)]. The incidence of adverse reactions was 8%(4/50) in the observation group including 3 cases of nausea, 1 case of vomiting. The incidence of adverse reactions was 4% in the control group (2/50), which 2 cases showed nausea. The number of patients who chose EPVL, ESWL or surgery for the subsequent treatment in observation group was 35 cases, 9 cases, and 6 cases respectively. The number of patients who chose EPVL, ESWL or surgery for the subsequent treatment in the control group was 35 cases, 10 cases and 5 cases respectively. There was no significant difference between the two groups (P>0.05). The VAS score after treatment of the observation group was lower than that of the control group (2.4±1.3 and 3.7±1.5, P<0.01). The total effective rate of the observation group was higher than that of the control group [94%(47/50) and 76%(38/50), P<0.01]. 46 patients underwent urinary ultrasonography to check the degree of hydronephrosis. The reduction rate of hydronephrosis was higher in the observation group than in the control group [54.5%(18/33) and 30.8%(4/13)], but there was no significant difference between the two groups (P=0.146). In the upper ureteral calculi, the VAS score of the observation group was lower than that of the control group (2.4±0.3 and 3.9±0.4, P<0.01). There was no significant difference in the total effective rate between the two groups. In the lower ureteral calculi, the observation group had low VAS score after treatment. In the control group (2.4±0.2 and 3.5±0.2, P<0.01), there was no significant difference in the total effective rate between the two groups; the middle segment stones were less included (10 in total) and were not discussed.@*Conclusions@#The external physical vibration lithecbole adopts " head high and low position" has better effect than "head low foot high position" in treatment of ureteral calculi with renal colic, and security is acceptable.

ABSTRACT

Objective: To compare the sedation induced by target-controlled infusion of propofol with that by propofol-remifentanil in third molar exaction surgery. Methods: 60 patients for third molar exaction were divided randomly into 2 groups(n = 30): group P(propofol group) and group PR(propofol-remifentanil group). In group P,a titrated infusion of propofol was started until the OAA/S score had reached level 3 in the patients,then the surgery began. In group PR,a infusion of remifentanil with a target plasma concentration of 1 ng /ml and a titrated infusion of propofol was started until the OAA/S score had reached level 3,then the surgery began. In all patients,the heart rate,blood pressure,respiratory rate,oxyhemoglobin saturation and narcotrend index were recorded during the operation. The reactions of the patients in the operation were recorded. The satisfaction of the patients and surgeons was asked. Results: The respiratory rate and the oxyhemoglobin saturation in group PR was lower than those in group P(P < 0. 05). No obvious adverse reaction was observed in the 2 groups. The satisfaction of the patients in the 2 groups was 30 /30 and 30 /30(P> 0. 05). Conclusion: The sedation induced by target-controlled infusion of propofol or propofol-remifentanil in third molar extraction is safe. The sedation under target-controlled infusion of propofol-remifentanil is better than that by propofol when inhalating oxygen.

ABSTRACT

Objective To investigate the risk factors of pulmonary hypertension (PH) after rapid ascent to high altitude in healthy young Chinese men .Methods A total of 552 non high altitude natives ( healthy young Chinese men ) were recruited in the study between June to August in 2012.The subjects were delivered to high altitude (3700 m) in 2 h by plane from low altitude (450 m).Demographic data including smoking , alcohol consumption , high altitude exposure histo-ry, body mass index (BMI) and age were collected within 24 h after arrival at 3700 m.Furthermore, the oxygen saturation ( SaO2 ) , blood pressure , heart rate , pulmonary artery systolic pressure were measured using the echocardiography system . Analysis of risk factors of PH was performed by logistic regressions .Results The incidence of PH was 23.10%.SaO2 was significantly lower in the higher-pulmonary artery systolic pressure group (higher-PASP)[(86.10 ±3.34)%] than that in the normal-PASP group [(89.09 ±2.65)%, P<0.01].Smoking, alcohol consumption, high altitude exposure history, BMI, age, systolic blood pressure , diastolic blood pressure , heart rate were not significantly different between the two groups mentioned above .Logistic regressions revealed that lower SaO 2 (OR:0.711,95% CI:0.647-0.782, P<0.01) was an independent risks factor of PH .Conclusion Low SaO2 is an independent risk factor of PH upon rapid arrival at 3700 m in healthy young Chinese men .However, smoking, alcohol consumption , high altitude exposure history , BMI, age, blood pressure and heart rate are not risk of PH .These observations will provide valuable clues to theoretical studies on PH and prevention of PH .

ABSTRACT

Objective To study the regulatory effect of ethanol extract of glossy privet fruit and its monomer tyrosol on the adhesion and migration of human epidermal melanocytes.Methods Epidermal melanocytes were isolated from human foreskin,and subjected to a primary culture.Mter 3-5 passages,the melanocytes were treated with various concentrations of ethanol extract of glossy privet fruit (0.0375-0.6 mg/ml)and tyrosol (0.125-2 mmol/L) for 24-72 hours.The XTT colorimetric assay was carried out to evaluate the proliferation of melanocytes,fibronectin (FN)-coated culture plates were used to evaluate the adhesion activity of melanocytes,and Transwell assay was conducted to assess the migration activity of melanocytes.Confocal laser microscopy was utilized to observe the structure and distribution of actin cytoskeleton in melanocytes,and cellular fluorescence intensity was determined by a semi-quantitative analysis.Statistical analysis was carried out by using unpaired t test.Results The adhesion activity of melanocytes to FN was significantly enhanced by the ethanol extract of 0.0375-0.6 mg/ml from glossy privet fruit (P < 0.05 or 0.01),and by tyrosol of 0.5-2 mmol/L (P < 0.05 or 0.01).As XTT assay showed,neither the ethanol extract of 0.15 mg/ml nor tyrosol of 2 mmol/L had cytotoxicity or promotive effect on cell proliferation.Hence,0.15 mg/ml and 2 mmol/L were determined as the working concentrations of ethanol extract and tyrosol respectively.The number of cells migrating through micropore membranes per high-power field (× 200) was 43.7 and 51.0 in melanocytes treated with the ethanol extract of 0.15 mg/ml and tyrosol of 2 mmol/L,respectively,significantly higher than that in untreated melanocytes (20.3,both P < 0.01).Compared with untreated melanocytes,those treated with the ethanol extract of 0.15 mg/ml and those with tyrosol of 2 mmol/L showed higher intracellular fluorescence intensity (P < 0.01) and more stress fiber bundles which congregated inside the cell membrane and around the nuclei.Conclusions The ethanol extract of glossy privet fruit and its monomer tyrosol can promote the adhesion and migration of human melanocytes in vitro,likely by promoting the congregation of actin cytoskeleton in melanocytes.
