Objective To explore the isometric attachment site of the posterolateral structure in the femoral lateral condyle and introduce the method of knee posterolateral complex(PLC) reconstruction with the semitendinosus tendon. Methods Isometric reconstruction of the chronic PLC injury of knee joint in 18 cases, were performed with the semitendinosus tendon from February 2001 to February 2005. Of all patients, there were 12 males and 6 females, average age was 39 years old(range, 19-52 years old). All cases were chronic injuries, with duration of 1.5-14 months. 3 cases were simple PLC injury, 10 cases were PLC injury with posterior cruciate ligament(PCL) injury, 2 of which had undergone PCL reconstruction about 6.5 months. 3 cases combined with anterior cruciate ligament(ACL) injury, 2 cases combined with ACL and PCL injury. To put in the double semitendinosus tendon from the bony tunnel of anatomical insertion of the fibular collateral ligment in caput fibulae and put out from the bony tunnel of anatomical insertion of the popliterofibular ligment in the caput fibulae, then fix them respectively in the isometic bony tunnel of the femoral lateral condyle. The posterolateral stability of the knee was evaluated mainly through examination varus instability of knee and external rotation range of leg. Results It was relatively isometric from the femoral attachment site of the popliteal tendon to the anatomical insertion of the popliterofibular ligment in the caput fibulae. The better isometric attachment site was from the anatomical caput fibulae attachment site to 8-10 mm in front of the anatomical femoral attachment site of the lateral collateral ligament. The average follow-up period was 14 months(12-24 months). There was no varus knee instability in full extension. At 30? flexion, one-grade varus instability was found in 2. At 30? and 90? flexion, external rotation range increased by 6? in 3 cases, remained the same in 14 cases, and decreased in 1 case, all compared with the healthy side. Conclusion The method provided good stability for the knee and acquired satisfactory clinical results.

Objective To study the transformation mechanism of triterpenes in processing of Alisma orientalis. Methods The triterpene transformations of A. orientalis pre and post-processing were comparatively analyzed by techniques of HPLC and Packed Column Supercritical Fluid Chromatography (SFC). Results In baked processing (70 ℃) of A. orientalis, little alisol B 23-acetate was transformed into alisol A 24-acetate and alisol B.However, more alisol B 23-acetate was transformed into alisol A 24-acetate and alisol B, then both of them were further transformed into alisol A in processing under high temperature (160-200 ℃). Conclusion Transformation of alisol B 23-acetate has two routes when A. orientalis is processed under high temperature: For one, alisol B 23-acetate is rearranged into alisol A 24-acetate which could be deacetylated into alisol A; for the other; it is deacetylated into alisol B first, then transformed into alisol A.

Objective To evaluate modified retroperitoneal laparoscopic resection of renal cyst. Method Thirty-six patients with renal cyst were treated by modified retroperitoneal laparoscopic resection of renal cyst,summarized the clinic data and follow-up the effect. Results All 36 cases were operated suc-cessfuUy without changing to opening operation,average operation time (50 ± 35)min,no complications oc-curred and no recurrence was found. Conclusions The modified retroperitoneal laparoscopic resection of renal cyst with two 5 mm-trocars and one 10 mm-trocar has less trauma than classic laparoscopic operation. It is one of mini-trauma operation method which is worth to be popularized in clinic.

Objective To discuss the anatomical and radiographic parameters of medullary screw fixation of anterior acetabular column so as to provide reference for clinical application. Methods Thirty cadaveric pelvic specimens (including 18 males and 12 females) were involved in the study and fixated re-spectively with 30 retrograde medullary cannular lag screws through pubic tubercle to acetabular posterosu-perior on the left side and with 30 anterograde medullary cannular lag screws through acetabular posterosu-perior to pubic tubercle on the right side. Then, two-dimensional multiplanar CT reconstruction was done to measure the angle and length of the anterograde and retrograde medullary screw trajectory, the relationship of screws with acetabular bone and penis and determine optimal point and angle of screw insertion. Re-suits The entrance of the retrograde medullary screw was located at pubic tubercle, with vertical dimen-sion of ( 17.15±1.82) mm to pubic symphysis and that of (20.51±2.19) mm to superior margin of pu-bis. For the anterograde medullary screw, the distance from the entrance of the screw to greater sciatic notch was (33.25±2.35) mm, with safe insertion angle of (32.1±2.7)°of cephalon tilting at the sagittal plane and (46.5±3.6)°of lateral tilting at the coronal plane. The entrance angle of the anterugrade and retrograde medullary screw trajectory was similar, with only opposite direction and minor difference between the left and the right sides (P>0.05). The length of medullary screw trajectory was (119.5±2.2) mm, with insignificant difference between both sides ( P >0.05). The maximum diameter of the screw was 7.2 mm. Conclusions Medullary screw fixation of anterior acetabular column is clinically feasible but needs rather high accuracy and can be used as an alternative to plate fixation.

Objective To explore a method to improve the nutritional state and immune function of patients after radical gastrectomy,and to decrease postoperative complication rate and accelerate recovery from operation.Methods In line with the concept of fast tract surgery (FTS),a new perioperative nutritional schedule was made for patients prior to radical gastrectomy,ehich included preoperative nutritional risk screen and prophylactic enteral nutrition,early postoperative light enteral nutrition,early ambulation and perioperative nursing care.Patients with gastric cancer were randomly assigned into fast track group or a simple control group.New perioperative schedule was executed in the patients of fast track group and traditional nutrition support in control group.After operation,serum albumen was measured to evaluate the patient's nutritional state and serum IgA to evaluate gastrointestinal immune function.In addition,the time to passage of flatus,postoperative recovery time and complication rate after operation were compared.Results Patiens in FTS group (n=35) showed higher serum albumin and serum IgA on d1 and d3 after operation than those in the control group (n=25) (P

Objective To compare the clinical effect of non-operative and operative treatment for flail chest.Methods A retrospective case control study was made on 60 cases of flail chest treated from March 2013 to April 2016.There were 42 males and 18 females,at the age range of 36-62 years [(49.8 ± 10.3)years].According to the treatment methods,the patients were divided into non-operation group (28 cases) and operation group (32 cases).Chest CT,pulmonary function and 36-item short-form health survey(SF-36) were measured in all patients 3 months and 6 months after injury.Differences in atelectasis,chest wall deformity,delayed fracture healing,pulmonary function and life quality were analyzed between the two groups.Results Compared to non-operative group at postoperative 3 months,rates of atelectasis,chest wall deformity and delayed fracture healing in operation group were obviously lower,while indices of pulmonary function pulmonary function including forced vital capacity (FVC),forced expiratory volume in one second(FEV1),one second rate (FEV1/FVC) and maximal voluntary ventilation measured value (MVV) in operation group wcre higher,and SF-36 parameters including physical functioning (PF),role-physical (RP),bodily pain (BP),general health (GH),vitality (VT),social functioning (SF) and mental health (MH) in operation group were better (all P ＜ 0.05).As to the data measured 6 months after injury,there were no significant differences between the two groups,except that the rate of chest wall deformity in non-operative group (6 cases,39％) was higher than that in operation group (11 cases,19％) (P ＜ 0.05).As to c hest CT,indices of pulmonary function and SF-36 parameters (P ＜ 0.05),there were no significant differences within operation group at postoperative 3 months and 6 months (P ＞ 0.05).Non-operation group showed better results in rate of atelectasis,rate of delayed fracture healing,indices of pulmonary function and SF-36 parameters measured 6 months after injury than the detections at postoperative 3 months (P ＜ 0.05),without difference in rate of chest wall deformity (P ＞ 0.05).Conclusions Surgical treatment of flail chest can accelerate fracture healing,reduce rate of chest wall deformity and improve life quality of patients early compared to non-operative treatment.Although there is no obvious difference in life quality of patients between operative and non-operative treatment 6 months after injury,but the chest wall deformity remains significantly different.
