s:Objective Discuss the application of CTA for renal vascular control in laparoscopic renal transplantation of relative renal donors. Methods 83 cases of relative renal transplantation donors which are completed in our department during March 2007 to Junuary 2012 were divided into 3 Groups. There were 35 cases in group A ( laparoscopic nephrectomy with preoperative CTA examination) , 15 cases in group B ( laparoscopic nephrectomy without preoperative CTA examination) , and 33 cases group C ( conventional nephrectomy) . In group A, the location and quantity of renal arteries and veins were observed with preoperative CTA to make plan for vascular control. And the oper-ation time, amount of bleeding, vascular injury cases, the renal warm ischemia time in the graft, mean time of postoperative hospitalization were compared with those of group B and group C. Results 5 cases of renal vascular anomalies were observed in Group A, including 2 cases of single accessory renal artery, 2 cases of early branch of renal artery and 1 case of double renal veins. And all of them were intraoperatively comfirmed. 3 cases of renal vascular anomalies were observed in group B, including 1 case of renal arteriovenous ectopic, 1 case of injury in the accessory renal artery with diameter of 0. 6 cm, and it were given artery elongation with inferior epigastric artery postoperatively, and 1 case of renal vein injure during blocking lumbar vein with Hemolock which were repaired postoperatively. 5 cases of renal vascular anomalies were observed in group C, including 1 case of single accessory renal artery, 3 cases of early branch of renal artery, and 1 case of accessory renal artery with the diameter of 0. 1cm in the right renal was injured during surgery. The operation time, amount of bleeding, cases with vascular injury , renal warm ischemia time of donor , and the mean time of postoperative hospitalization in group A were superior to those in group B and group C. Conclusion CTA is a simple noninvasive imaging method, which can provide the details of the renal vascular preop-eratively to ensure the safety of patients during surgery and improve survival quality of donor renal, and it is of great advance in laparoscopic renal transplantation of living-related renal donors.

BACKGROUND:In order to avoid heterotopic ossification after total hip arthroplasty, nonsteroidal anti-inflammatory drugs are commonly used for prevention.
OBJECTIVE:To compare the effect of meloxicam and indomethacin in the prevention of heterotopic ossification after total hip arthroplasty.
METHODS:Fifty-one patients who treated in the Department of Orthopedics, the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine from 2010 to 2011 were col ected. Among the 51 patients, nine patients were treated with bilateral total hip arthroplasty, and al the patients had total hip arthroplasty with the posterior-lateral approach. The patients were divided into the control group and the experimental group according to the drugs used after replacement, and the patients in the two groups were administered with indomethacin sustained-release tablet 25 mg+omeprazole capsule 20 mg or meloxicam tablet 15 mg after replacement.
RESULTS AND CONCLUSION:There were no significant differences in the incidence of heterotopic ossification, pain, modified D’Aubigne and Postel scores after replacement between two groups (P>0.05). But, the gastrointestinal adverse reactions of the experimental group were less than those of the control group. The application of meloxicam only can effectively avoid the heterotopic ossification and release pain. Consequently, we recommend meloxicam as postoperative drug for the prevention of heterotopic ossification and pain remission fol owing total hip arthroplasty.

This article describes a novel Multifunctional and Transparent Urinary System Model (MTUSM), which can be applied to anatomy teaching, operational training of clinical skills as well as simulated experiments in vitro. This model covers kidneys, ureters, bladder, prostate, male and female urethra, bracket and pedestal, etc. Based on human anatomy structure and parameters, MTUSM consists of two transparent layers i. e. transparent organic glass external layer, which constraints the internal layer and maintains shape of the model, and transparent silica gel internal layer, which possesses perfect elasticity and deformability. It is obvious that this model is preferable in simulating the structure of human urinary system by applying hierarchical fabrication. Meanwhile, the transparent design, which makes the inner structure, internal operations and experiments visual, facilitates teaching instruction and understanding. With the advantages of simple making, high-findelity, unique structure and multiple functions, this model will have a broad application prospect and great practical value.

BACKGROUND:Medial open wedge high tibial osteotomy is an effective procedure for preserving the knee joint in patients with medial compartmental osteoarthritis.Previous studies have demonstrated that the forgotten joint score provides a lower ceiling effect and consistency of medial open wedge high tibial osteotomy outcomes compared to traditional assessment tools. OBJECTIVE:To identify predictive factors associated with the occurrence of a forgotten joint after medial open wedge high tibial osteotomy. METHODS:117 patients with medial open wedge high tibial osteotomy who were treated at First Affiliated Hospital of Guangzhou University of Chinese Medicine were selected,including 35 males and 82 females,with an average age of 61 years.They were followed up for at least 2 years.Patients were divided into a forgotten joint group(n=28)and a non-forgotten joint group(n=89)by evaluating whether they achieved forgotten joint after surgery.Univariate and multivariate logistic regression analyses were performed with preoperative patient characteristics and surgery-related factors as potential predictors. RESULTS AND CONCLUSION:(1)There were significant differences in the proximal medial tibial angle between the two groups before surgery(P<0.05).There were significant differences in the forgotten joint score,Knee Injury and Osteoarthritis Outcome Score,knee society knee score,function score,and patients joint perception between the two groups after surgery(P<0.05).There was a significant difference between the hip-knee-ankle angle and the medial proximal tibial angle after operation(P<0.05).(2)Univariate Logistic regression analysis showed that the medial proximal tibial angle had a significant influence on the forgotten joint before operation[OR=0.755,95%CI(0.635-0.897),P<0.001].There were significant effects on the forgotten joint of hip-knee-ankle angle and medial proximal tibial angle[OR=1.546,95%CI(1.242-1.924),P<0.001;OR=0.815,95%CI(0.713-0.931),P=0.003].(3)Multivariate logistic regression analysis showed that preoperative K-L grade 1 was a favorable factor for obtaining forgotten joints.Preoperative medial proximal tibial angle and postoperative hip-knee-ankle angle were independent predictors of forgetting joints,and they had a curvilinear relationship with the probability of achieving forgetting joints.When preoperative medial proximal tibial angle increased by 1°,the probability of achieving a forgotten joint decreased by 27.7%[OR=0.723,95%CI(0.593-0.882),P<0.001].Conversely,when postoperative hip-knee-ankle angle increased by 1°,the probability of achieving a forgotten joint increased by 46.4%[OR=1.464,95%CI(1.153-1.860),P=0.002].(4)The results showed that patients with preoperative knee osteoarthritis K-L grade 1,small medial proximal tibial angle(<85.5°),and large postoperative hip-knee-ankle angle(>176.0°)were predictors of forgotten joint.

Objective: To analyze the prevalence and related factors of pediatric flexible flatfoot (PFF) among 7-8 year old children in Changzhou, so as to provide a feasible basis for the prevention and treatment of PFF. Methods: From December 2023 to February 2024, a total of 1 685 children aged 7-8 from 10 primary schools in Changzhou were selected by stratified cluster random sampling method, and screened for PFF by using a foot optical assessment recording device. Information including sex, body mass index (BMI), diet, exercise and shoe wearing habits were collected. The valgus angle of the hindfoot was measured on the body surface by using an orthopedic measuring ruler in the standing position. Pain levels were evaluated by using visual analogue score (VAS) for children with flatfoot syndrome. Multivariate Logistic analysis was used to analyze related factors of PFF. Results: The overall detection rate of PFF was 27.4%, and there was a significant difference in the detection rate of PFF between boys and girls, with 30.3% and 24.1% respectively ( χ 2=7.96, P < 0.01 ). Most cases of PFF were mild flatfoot (60.8%) and bilateral ( 60.4% ). Approximately 13.2% of children with PFF had flatfoot syndrome, with a mean VAS of (2.86±0.73). About 56.1% of children with PFF had a normal valgus angle of the hindfoot. Sex, high BMI and preference for shoe last with front upturned shoe shape were positively correlated with the detection of PFF ( OR= 1.74, 1.54, 1.13, P <0.05). After stratified by sex, regular exercise in boys and age in girls were negatively correlated with the detection of PFF ( OR=0.40, 0.64, P <0.05). Conclusions The detection rate of PFF in 7-8 year old children is high. Additionally, PFF combined with flatfoot syndrome or valgus hindfoot is relatively rare and is likely to be underestimated, which emphasizes the importance of early detection and intervention for PFF.
