Objective To discuss the method and effect of large renal staghorn calculi by anatrophic nephrolithotomy (AN).Methods Fifty-two patients with large renal staghom calculi underwent AN.Bilateral renal calculi disease was present in 3 patients,so that a number of 55 procedures were operated.Preoperative evaluation included urinalysis,urine culture,renal function,and ultragound,CT,KUB and IVU.A flank incision was between the 11th and 12th ribs and the kidney was freed.After interrupted renal pedicle in situ hypothermia,the renal parenchyma incision was made along the avascular plane which is outside in the back of the kidney.The collecting system was opened.The calculi were removed.The collecting system was reconstructed.The renal parenchyma was closed and the renal circulation was reestablished.The protected management of renal function was made intraoperative.Postoperative follow-up consisted of urinalysis,renal function,ultrasound,KUB,IVU and ECT.Results The operative time was (117±45) minutes.The renal ischemia time WaS (29±15)minutes.Five cases underwent blood transfusion.Mean amount of blood transfusion was 230 ml.Four cases had remained calculi.The stone-free rate was 92.3%.No recent complication occurred after operation.Postoperative follow-up indicated that renal function was normal.Conclusions AN is the most appropriate method for patients with large renal staghorn calculi because of the highest stone-free rate,the lowest stone-recurred rate and a safe and effective operative procedure with less complication.Renal function damages just little through a series of protected management.Nephrectomy is avoided to part of patients.

Objective To explore the relation of stroke and metabolic syndrome (MS), and provide theoretical evidence for prevention of stroke and MS. Methods Five hundred stroke patients accompanied with MS were enrolled, and divided into different types according to the distribution of the components of metabolic syndrome and abnormal metabolic condition. The systolic blood pressure(SBP) ,diastolic blood pressure( DBP),fasting glycemia ( FPG ), triglycerides ( TG ), total cholesterol ( TC ), low density density lipoprotern-cholesterol (LDL-C), high density density lipoprotern-cholesterol (HDL-C)of each patient were detected and recorded. Results Among these stroke patients with MS, most patients were 60 - 69 years old ( 39.60% ), and there was no significant difference between two gender( P = 0. 545 ). Among each component of MS, hypertension was most related to MS;patients complicated with hypertension + hyperlipidemia + hyperglycemia were the most major proportion of stroke patients with MS(48. 00% ). Conclusion MS and its components are all risk factors for stroke,and the more complication the patients had,the more patients suffered from stroke with MS. Targeted interventions of different type of abnormal condition has important prevention effect on MS and stroke.

Microsurgery techniques have allowed the development of many new therapeutic methods in plastic surgery, but are difficult to master without hard training. It is very important to set up a standardized microsurgery curriculum and training system for broadening surgical skills training and investigating the plastic surgery specialist training strategy. In our experiences, a series of training models are needed, like non-animal models, non- living animal models, live animal models and so on. This paper shows the training strategy for the primary stage of microsurgery training, non-animal model and non-living animal model training.
