Objective:To explore the clinical effect ofpaishitang combined with tamsulosin hydrochloride on the patient with up per urinary calculi after extracorporeal shock wave lithotripsy (ESWL).Methods:120 cases with upper urinary calculi in our hospital from January 2015 to September 2016 were selected and divided into two groups according to the random number table,60 cases in each group.ESWL was given to both groups of patients and provided with tamsulosin hydrochloride postoperation,then paishitang were additionally given to the patients in the observation group.The clinical effect and changes of serum creatinine (Scr),neutrophil gelatinase as sociated lipocalin (NGAL),cystatin C (Cys-C) and glomerular filtration rate (GFR) levels before and after treatment were compared between two groups.Results:The total effective rate of observation group was 96.67％,which was 86.67％ in the control group,no signifi cant difference was found in the total effective rate between the two groups(P＜0.05).The stone discharge rate was 95.00％ in the observation group,which was significantly higher than that of the control group (P＜0.05);the incidence rate of renal colic was 6.67％,which was significantly lower than that of the control group(P＜0.05),the stone discharge time and the duration of hematuria were significantly shorter than those in the control group (P＜0.01).There was no significant difference in the recurrence rate between the two groups within one year (P＞0.05).The serum NGAL and Cys-C levels of both groups were gradually increased while the GFR levels were gradually decreased on the 1st,2nd day postoperation,but all the index mentioned above gradually recovered on the 3rd day postoperation.The levels of NGAL and Cys-C in the observation group were significantly lower than those in the control group on the 1st,3rd day postoperation while the GFR was significantly higher in the observation group than those of control group on the 1st,3rd day postoperation(P＜0.01).No significant difference was found in the Scr at different time points postoperation between two groups(P＞0.05).Conclusion:Paishitang combined with tamsulosin hydrochloride had significant clinical effect on thpatient with upper urinary calculus after ESWL and could effectively improve the renal injury induced by ESWL.

Objective To analyze the application of modified abdomen pathway for excising the adrenal huge pheoehromocytoma.Methods One patient(male,42-year-old)had adrenal huge pheochromocytoma.The pheochromocytoma was about 15.0 cm×8.0 cm×7.0 cm.After 3 weeks' preparations,the patient was operated.The operation was made through the modified abdomen pathway for excision,without excising the transverse on peritoneal,and the interference to organs of peritoneal was reduced.The tumor on adrenal gland adhered kidney very tightly.Expanded radical excision including tumor,kidney,adrenal gland was applied.Results The operative time was 300 rain and the volume of bleeding was about 1000 ml.In the operation process,blood pressure of the patient was stable,the visual field of operation was satisfactory.Blood pressure of the patient returned normal 6 months postoperatively.And there was no indication of tumour relapse or matastasis.Conclusion The modified abdomen pathway can expose the satisfactory visual field,and is safe and effective for adrenal gland tumor operation.

We developed and designed a new type of artificial trachea. The basic structure of the artificial trachea was polytetrafluoroethylene vascular prosthesis linked with titanium rings on both sides. Dualmesh was sutured on titanium rings. This experimentation follows the replacement of trachea in dogs with a combined artificial trachea to investigate the feasibility of this type of prosthesis. Sixteen dogs were implanted with the combined artificial trachea after resection of 5 cm of cervical trachea. The 5 cm-long trachea of dogs on the necks were resected and the reconstruction of the defect of the trachea was performed with trachea prosthesis. According to the method of trachea reconstruction, the models were divided into 2 groups, artificial trachea implantation group (the control group, n = 8) and group of artificial trachea implantation with growth factor (the experimental group, n = 8). Then computer tomography scan (CT), bronchoscope and pathologic examination were conducted periodically to observe the healing state of the hybrid artificial trachea. None of the dogs died during operation of cervical segmental trachea construction. But four dogs in the control group died of apnea in succession because artificial trachea was displaced and the lumen was obstructed, while 2 dogs died in the experimental group. In the first month there was granulation around anastomosis with slight stenosis. The rest of dogs were well alive until they were sacrificed 14 months later. The mean survival time of the experimental group was longer than that of the control group. The rate of infection, anastomotic dehiscence, severe stenosis and accidental death in the experimental group were lower than the control group (P < 0.05). Artificial trachea was encapsulated by fibrous tissue and no mucous membrane was seen in the lumen of the artificial trachea. The artificial trachea can be used to reconstruction of the defect of the trachea with long-term survival of the animals. The unique design of artificial trachea reduces stenosis around anastomosis effectively but infections and split or displacement of the artificial trachea are still major problems affecting long-term survival of the animals. Application of growth factors to a certain extent promotes tissue healing by changing the local environment.

Compared with quercetin group,except AUC0-24 h was significantly decreased in BL2 group(P<0.05),there were no significant differences in AUC0-24 h,MRT0-24 h,tmax or cmax in BL1 group,BL2 group and BL3 group(P>0.05). CONCLUSIONS:Quercetin can inhance the related indexes of rutin in rats in vivo.

Objective To studythe cephalocaudal relationship ofabdominal aortic bifurcation relative toumbilicus and iliac crest vertex and their correlations with abdominal adipose tissue thickness and age. Methods The vertical distances,cephalocaudal relationship and other related anatomic parameters of aortic bifurcation relative to umbilicus and iliac crest vertex in 108 patientswere measured by consecutive abdominal CT scanning. The correlations of the acquired data with abdominal adipose tissue thickness and age were analyzed using Pearson correlation coefficient. Results Umbilicus was located at cephalad to aortic bifurcation in 67 patients(62.0%), caudal in 34(31.4%)andthe same level in 7(6.5%),with the vertical distance of(4.53 ± 17.51)mm to the aortic bifurcation. No statistically significant relationship was found between abdominal adipose tissue thickness(P>0.05) or age(P>0.05). Iliac crest vertex relative to aortic bifurcationwas located at cephalad,caudal and the same level in 31,71 and 6 patients,taking up 28.7%,65.7%and 5.6%,respectively. Its vertical distance to the bifurcation was(-6.34 ± 14.49)mm,nonrelated with abdominal adipose tissue thickness(P>0.05),but positively correlated with age(P<0.01). The difference in the cephalocaudal relationship of aortic bifurcation relative to umbilicus and iliac crest vertex was statistically significant(P<0.01). Conclusion Compared with iliac crest vertex,umbilicus is an important landmark of locating abdominal aortic terminal occlusion position in vitro because it mostly lies cephalad to aortic bifurcation in the front of the body,not easy to vary with abdominal adipose tissue thickness and age.

Objective To investigate the effect of diuretic (furosemide) therapy on kidney injury induced by melamine and cyanuric acid in rats. Methods 36 male Spragne Dawley rats were random disided into 3 groups. Group A was treated with 2mL of water daily, group B was treated with melamine and cyanuric acid ( each 100 mg/kg) daily for 4 days and then 2ml of water daily, group C was treated with the same as group B at the first 4 days and then treatment with furosemide (20mg/kg) daily. Samples of blood and 24h urine were collected to detective biochemical indexes, and kidney sections were performed on days 4 and 11 ( each end point, n = 6). The kidneys were observed with histopathology and renal crystal deposition scores were determined. Results On the 4th day, group B and group C were resulted in acute kidney injury such as oliguria [ ( 3. 39 ± 1.02 ) ml, ( 3. 20 ± 0. 86 ) ml ] and high serum creatinine [ ( 153.54 ±27. 08)μmol/L, (160. 11 ± 19. 55)μmol/L] and renal melamine cyanurate crystal were found in the renal tissues. On the 11th day, the renal crystal deposition score in the rats was reduced by 9. 52% ( P >0. 05). Compared with those of the 4th day in group B, it reduced by 63.63%( P <0.05) in group C. Urine volume were increased significantly compared with those of the 4th day( P < 0. 05 ) in group C [ from (3.20±0. 86)ml to (25.96 ±5.97)ml] and group B [ from(3. 39 ± 1.02)ml to (8. 57 ± 1.66)ml] , and Urine volume in group C was increased significantly more than that in group B ( P < 0. 05 ). The serum creatinine was obviously reduced as compared with those of the 4th day in group B and C( P <0.05), from[ (153. 54±27.08) μmol/L] to [ ( 106. 10 ±5.53) μmol/L] in group B and from [ ( 160. 11 ± 19. 55) μmol/L] to [ (67. 17 ± 12. 80 ) μmol/L] in group C, but the serum creatinine in group B was still higher than that in group A and C ( P < 0. 05). Conclusions Furosemide can attenuate the damage of acute kidney injury induced by melamine and cyanuric acid.
