Objective To discuss the cause,treatment and prevention of splenic injury during the urological surgery.Methods The clinical data of 16 cases with splenic injury in operation for renal and adrenal tumors in 496 cases were retrospectively analyzed.Nine cases were left radical nephrectomy,3 cases were left renal hamartoma enucleation,4 cases were left adrenal tumor resection.Damage located at outer edge of the spleen in 8 cases,the splenorenal ligament in 6 cases,and the splenic hilum in 2 cases.In these 16 cases,14 patients spared the spleen (Ⅰ Grade injury 8 cases,Ⅱ grade 6 cases).The injuryed spleen was directly pressed with hemostatic gauze in 3 cases; 5 patients used coagulation,bonding,hemostatic gauze to stop bleeding; 2 cases of grade Ⅱ injury used U-shaped suture and coated with fibrin glue,then compressed with hemostatic gauze to stop bleeding; 2 cases of grade Ⅱ injuries with the greater omentum stitched into the seam,sprayed biological glue,were compressed with gelatin sponge; 2 cases of grade Ⅱ injury underwent splenic artery branch ligation.The other 2 cases (1 Ⅱ grade and 1 Ⅲ grade) underwent splenectomy.Results All of the 16 patients were cured and followed up for 6 months to 5 years.There was no delayed bleeding of spleen and splenic dysfunction.One patient died of tumor recurrence 6 months after operation.Conclusions Splenic injury is a common complication during urological surgery,especially the tumor is large or adhered to spleen in the upper pole of left kidney.Once spenic injury occurs,doctors should choose the right treatment plan according to surgical injury,and try to save the spleen.

Objective To investigate the changes of bone tunnel and differences of clinical outcomes after anterior cruciate ligament (ACL) reconstruction with hamstring tendons from autografts and allografts. Methods The study involved in 61 patients with ACL injury undergone arthroscopic ACL reconstruction from June 2008 to November 2009.According to ACL graft differences,61 patients were assigned to two groups,ie,Group A ( reconstruction with tendon allografts,n =27 ) and Group B ( reconstruction with tendon autografts,n =34).MRI examination was performed one week and 6-12 months post-operatively to measure the sagittal bone tunnel diameters at the aperture location,at the location of 1cm away from the aperture and at the widest location of tunnel.Taking the bone tunnel diameter at each location one week post-operatively as the measurement criteria,the differences of bone tunnel diameters at each corresponding location were analyzed statistically.Lysholm score was used to evaluate the clinical effects in the two groups. Results Group A and B were followed up for average 8.4 months and 8.5 months,respectively.Pre-operative clinical data of the two groups had no significant difference.MRI follow-up showed that the tunnel diameters at femoral side and tibial side both had different degree of enlargement.Meanwhile,the enlargement degree at the tibial side was larger than that at the femoral side,with no statistical differences of the two groups regarding tunnel enlargement of the three measurement locations at femoral and tibial sides.Joint stability in all patients was good.The two groups showed no significant difference in Lysholm score after operation ( P ＞ 0.05 ). Conclusions Graft difference is a factor for bone tunnel enlargement after ACL surgery.Autologous and allogenic tendons show no difference in their role in bone tunnel enlargement after ACL surgery or correlation with clinical effects.

BACKGROUND:Femoral offset reconstruction is significant for recovering strength of abductor and the balance of soft tissue tension surrounding hip joint, maintaining joint stabilization, restoring joint function, reducing limping after replacement, decreasing prosthetic abrasion, and the incidence of joint prosthesis dislocation.
OBJECTIVE:To discuss effect of femoral offset reconstruction on hip joint function in total hip arthroplasty.
METHODS:We comparatively analyzed 20 patients (20 hips) undergoing the modular prosthesis (S-ROM) total hip arthroplasty and 19 patients (20 hips) undergoing the one modular prosthesis (Corail) total hip arthroplasty at the same time. According to Harris hip score and radiography results, hip joint function and femoral offset reconstruction rate were comparatively studied in both groups.
RESULTS AND CONCLUSION:No infection, fracture, dislocation, deep venous thrombosis or neurovascular injury occurred in either group. Clinical fol ow-up results:In the modular prosthesis and one modular prosthesis groups, there was no significant difference in preoperative Harris hip score between the femoral offset reconstruction and non-reconstruction groups (P>0.05). At 12 months and the latest fol ow-up, the Harris hip score was higher in the patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P<0.05). The range of abduction of hip joint was larger in patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P<0.05). Radiographic fol ow-up results:significant differences in the rate of femoral offset reconstruction were detected between the modular prosthesis and one modular prosthesis groups (χ2=3.956, P<0.05). 39 (98%) femoral stems were in neutral position and one (2.5%) was in mild valgus. There was no significant difference in the abduction angle and the anteversion angle between patients with and without femoral offset reconstruction (P>0.05). These results indicated that functional recovery and the range of abduction were better in patients with femoral offset reconstruction than those without femoral offset reconstruction. Modular prosthesis has a high rate of femoral offset reconstruction.

Objective To study the expression of Paxillin and VCAM-1 in esophageal carcinoma and the relationship between the expression of Paxillin, VCAM-1 and carcinogenesis and progression of esophageal carcinoma. Methods Paxillln and VCAM-1 expression were detected in 24 normal esophageal mucosa and 94 primary tumor tissues with SP immunohistochemistal method. Results The expression rate of PaxiUin was related to invasive depth (P <0.01) ,clinical staging (P <0.01) and metastasis of lymph node (P <0.05). The expression rate of VCAM-1 was related to invasive depth (P < 0.01) ,clinical staging (P < 0.01) and metastasis of lymph node (P<0.05). There was a positive correlation between Paxillin and VCAM-1 expression in this study (r = 0. 247 ,P < 0.05). Conlusion Paxillin and VCAM-1 are over expressed in esophageal carcinoma. They can be used as valuable biomakers to evaluate biological characteristics in esophageal carcinoma.

ObjectiveTo analyze the Envelope (E) gene of type 1,2,3 dengue virus isolated fromGuangzhouin2010, andtoinvestigatetheinfectionsourceandvirusgenotypes.MethodsEighty-five serum samples were collected from 85 patients in acute phase of dengue fever.Dengue virus was cultured and isolated by C6/36 cells.The whole length of E gene was amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) and then sequenced.The phylogenetic tree was drawn by neighbor-joining method.The bioinformatics analysis was performed by combining the phylogenetic information and the epidemiologic data.ResultsSix strains of type 1 dengue virus,two strains of type 2 dengue virus and six strains of type 3 dengue virus were isolated from 85 samples.The E gene sequence of these strains was obtained by sequencing.The phylogenetic analysis showed that type 1 and 3 dengue virus belonged to two genotypes (Asian and South Pacific ocean,India subcontinent and Southeast Asia/South Pacific ocean,respectively),and type 2 dengue virus belonged to one genotype (Malaysia/India subcontinent).ConclusionIt's presumed that all strains of type 2 dengue virus are imported,four strains of type 1 dengue virus are imported and four strains of type 3 dengue virus arc imported,the remaining two stains of type 1 and two stains of type 3 dengue virus need mosquito intermediary research further to prove their origins.

ObjectiveTo evaluate the value of the measurement with a scale in arthroscopic anatomic anterior cruciate ligament (ACL) reconstruction.Methods Thirty-six patients with unilateral ACL-deficient knees were divided into single bundle group and double bundle group based on the length of the major axis of the native ACL footprint measured with a scale.Consistent with the International Knee Documentation Committee (IKDC) scoring systems,Lysholm knee scoring scale and Tegner activity rating were used to evaluate the clinical results,and data from 23 to 26 months follow-up were gathered and analyzed statistically.ResultsIn terms of IKDC evaluation,19 patients( 90.4％ ) in the double band group and 13 patients( 86.7％ )in the single band group were graded as normal or nearly normal ( Z =7.82,6.33 ; P ＜ 0.05 ).The mean Lysholm scores were 93.8 ± 9.9 and 94.2 ± 9.6 and the mean Tegner scores were 6.6 ± 1.9 and 6.5 ± 1.7 for the double and single band groups,respectively( t =2.31,5.60,3.55,7.09 ;P ＜0.05 ).ConclusionArthroscopic measurement with a scale combined with other traditional methods to determine the tunnel location is easy to conduct and intuitional to understand.It could be useful in anatomic ACL reconstruction.

Objective To investigate the experience in management of the high risk benign prostatic hyperplasia (BPH) patients in order to improve the safety of the operation.Methods The high-risk factors of 115 patients with BPH who had been treated with transurethral resection of prostate (TURP) were analyzed.The blood pressure of hypertensive patients should be controlled below 140/90 mm Hg.The patients with myocardial infarction should be in stable condition for more than 6 months.Smoking cessation,oxygen inhalation,and pulmonary function training should be carried out during the perioperative period in patients with chronic obstructive pulmonary disease,correct expectoration methods and rational use of antibiotics were also needed to improve the maximum amount of pulmonary ventilation to more than 70％.The blood-glucose of diabetic patients should be controlled below 8 mmol/L by insulin.Catheter was indwelled in patients with chronic obstructive renal insufficiency for more than 2 weeks so that the blood Cr could be below 130 μmol/L.Anticoagulant therapy should stop at least 5 days before surgery.Patients were encouraged to have physical training early after surgery and to have ankle stretch movement when they recovered form anesthesia,and pressure cycle drive therapeutic apparatus were also used to prevent deep venous thrombosis.Results All the patients tolerated TURP safely.Operation time was 30 to 60 min,the weight of the resection prostate tissue was 12 to 37 g,blood loss was 80 to 150 ml,and catheterization time was 3 to 7 days.The overall incidence of complications was 1.7％.There were 2 cases with deep venous thrombosis,who recovered after anticoagulant therapy.There were no pulmonary infection,bleeding,TUR syndrome,and other complications.Conclusion Correct analysis and effective management of the perioperative risk factors in high-risk BPH patients treated with TURP can improve the safety of the operation and reduce the complications.
