ObjectiveToevaluatetheclinicalvalueoflaparoscopicrenalcystdecorticationandopencyst decortication surgery in the treatment of polycystic kidney disease.Methods Various clinical parameters were retro-spectively analyzed in 108 patients with polycystic kidney,include laparoscopic 60cases and open surgery 48cases.The observation indexes include operative time,operative bleeding,restoration time of bowel functions,postoperative drain-age volume,hospital time,postoperative complications,kidney function,blood pressure,and the clinical effects were estimated.Results In the laparoscopic group,the average operation time was (57.7 ±13.2) min,the average blood was (35.9 ±17.3)mL,the average time of exsufflation was (1.6 ±0.7)d,the average postoperative drainage volume was (23.2 ±4.3)mL,the average hospital time was (5.1 ±0.8)d.As compared with the open surgery group,the op-eration time,hospital stay,operative bleeding,postoperative drainage and hospital time of the laparoscopic group short-ened significantly(all P<0.05).The complication rate of the laparoscopic group and open surgery group were 5.0%and 16.7%separately.The complication incidence was significantly lower in the laparoscopic group than that in the open surgery group(P<0.05).At 3 months postoperative,the levels of serum creatinine(Cr),urea nitrogen(UN)and systolic blood pressure were obviously decreased compared with preoperative.There were no significant difference be-tween the two groups(P>0.05).The follow-up data showed that the cure rate and effective rate of the open surgery group were 81.2%and 18.8%,and the cure rate and effective rate of the laparoscopic group were 85.0% and15. 0%respectively.There were no significant difference of the clinical effects between the two groups (P >0.05). Conclusion The laparoscopic was superior to the open surgery in the operation time,hospital time,operative bleed-ing,postoperative drainage and hospital time.Laparoscopic renal cyst decortication in polycystic kidney is open surgery safer,little injury,quick recovery.Laparoscopic renal cyst decortication is safe and effective therapy,which can be used as primary surgical treatment for patients with polycystic kidney.

Objective To establish ecological suitability zone of Forsythia suspensa(Thunb.)Vahl in Shanxi Province;To study the quality regionalization of Forsythia suspensa(Thunb.)Vahl from different producing areas in Shanxi Province;To provide reference for reasonable planting and wild tending of Forsythia suspensa(Thunb.)Vahl.Methods Maximum entropy(MaxEnt)model and ArcGIS software were used to study the ecological suitability of Forsythia suspensa(Thunb.)Vahl in Shanxi Province;By screening the main environmental factors and combining them with the content of forsythoside and forsythoside A in Forsythia suspensa(Thunb.)Vahl of different regions,a quality zoning of Forsythia suspensa Thunb.Vahl medicinal materials in Shanxi Province based on forsythoside,forsythoside A and environmental factors was constructed.Results The ecological suitable areas of Forsythia suspensa Thunb.Vahl in Shanxi Province were mainly distributed in the southern part of Shanxi Province,mainly in Linfen,Yuncheng,Changzhi,and Jincheng.The general contents of forsythoside and forsythoside A in the Forsythia suspensa(Thunb.)Vahl medicinal material were gradually reduced from southern part to northern part of Shanxi Province.The comprehensive quality was high in southern part of Shanxi Province,mainly in Linfen,Changzhi,Yuncheng and Jincheng.Conclusion The results of this study are consistent with the actual survey.The southern part of Shanxi province is a suitable planting area for high quality Forsythia suspensa(Thunb.)Vahl,which provides a reference for the standardized planting and wild tending of Forsythia suspensa(Thunb.)Vahl.
