Objective To explore the characteristics of diagnosis a nd treatment of testicular trauma. Methods A retrospective study was done on 30 cases of testicular trauma. The treatment effects of non -operation and operation on different types of injuries were observed and com pared. Results Follow-up time ranged from two months to tw o years. There were three cases with testicular atrophy, one with chronic pain l asting for one year and eight with non-operation. All of 22 cases treated with surgical operation were good except for one with sperm disorder due to bilateral testicular trauma. Conclusions Testicular trauma is a speci al type of trauma. Ultrasound is an important diagnostic method for testicular trauma. Surgical exploration should be performed as soon as possible so as to a void testicular atrophy and sperm disorder.

BACKGROUND:Deluxe-PS knee prosthesis is designed based on the anatomical characteristics of the Chinese peoples’ knee joint, especial y the morphological features of femoral condyle. The distance between median and lateral knee prosthesis femoral condyle is less than that of the imported prosthesis for 3.5 mm.
OBJECTIVE:To explore the short-term efficacy of Deluxe-ps knee prosthesis in simultaneous bilateral total knee arthroplasty.
METHODS:Fifteen knee osteoarthritis patients (30 knees) were included as the experimental group, and treated with simultaneous bilateral knee arthroplasty by Deluxe-ps knee prosthesis. Twenty patients (40 knees) in the control group were treated with simultaneous bilateral knee arthroplasty by PFCSigma knee prosthesis. The knee society score, hospital for special surgery knee score and knee joint range of motion were compared between two groups;the operation time and the intraoperative blood loss were compared between two groups.
RESULTS AND CONCLUSION:The patients in both groups were fol owed-up for 12 to 24 months, with an average of 16 months. Postoperative knee pain was relieved, and the joint function was recovered satisfactorily. The knee society score, hospital for special surgery knee score and knee joint range of motion in two groups were improved significantly after treatment (P<0.05). There were no significant differences in postoperative knee society score, hospital for special surgery knee score and knee joint range of motion between two groups (P>0.05), and there was no significant difference in intraoperative blood loss between two groups (P>0.05), while there was significant difference in operation time between two groups (P<0.05). The results showed that the short-term effect of Deluxe-ps knee prosthesis in simultaneous bilateral total knee arthroplasty was satisfied.

Objective To investigate the imaging manifestations of congenital intestinal malrotation. Methods The clinical data of 92 infants with congenital intestinal malrotation admitted from January 1993 to December 2012 were studied retrospectively. All the 92 cases enrolled in this study were diagnosed based on imaging examinations and confirmed surgically. The imaging features of four examinations including plain abdominal radiography, upper gastrointestinal radiography, lower gastrointestinal angiography and ultrasound examination were analyzed. Results The percentage of the infants who presented with the initial clinical symptoms of vomit, blood stool and abdominal dilatation was 87.0%(80/92), 3.3%(3/92) and 1.1%(1/92), respectively, and eight cases [8.7%(8/92)] received prenatal ultrasound, which showed intestinal malrotation. Clinical examination showed no abdominal abnormalities in 68 (73.9%) cases. Seventy-seven cases underwent plain abdominal radiography, revealing intestinal obstruction in 31 cases. Thirty-six cases underwent upper gastrointestinal radiography, which revealed malrotation in 14 cases, and duodenal complete/incomplete obstruction or stenosis in 19 cases. Twenty-two cases underwent lower gastrointestinal angiography, and all of them were diagnosed as malrotation. Seventy-nine cases were examined with abdominal ultrasonography, and 58 cases were diagnosed as malrotation. Conclusions Rational selection of imaging examinations can improve the preoperative diagnosis. When congenital intestinal malrotation is suspected, abdominal ultrasound should be done as the first optional examination. At the same time, plain abdominal radiography should be selected accordingly. When intestinal malrotation with or without midgut volvulus is suggested, surgery should be performed as early as possible. When the diagnosis is not clear, upper or lower gastrointestinal radiography should be done.

Objective To explore the optimal combination of parameters for the maximum spatial cluster size and maximum temporal cluster size of scan statistics. Methods The daily incidence data of hand-foot-and-mouth disease (HFMD) in Jingzhou in 2016 was collected as data source. The maximum spatial cluster sizes were set to 50%, 40%, 30%, 20%, and 10% of the population at risk. The maximum temporal cluster sizes were set to 7d, 14d, 30d, and 60d. A total of 20 parameter setting schemes were formed and spatial-temporal scanning was conducted one by one. The areas where the number of towns covered by the scanning area was less than 25 were selected, and the clustered epidemic of hand-foot-mouth disease can be detected at the same time in Xiejiaping Town of Songzi City and Sanzhou Town of Jianli County. The combination of large LLR and RR values was the optimal parameter setting. Results When the spatial windows were set to 20% of the population at risk, and the temporal windows were set to 30d, a total of 6 aggregation areas were detected. The number of covered townships was less than 25, and the clustered epidemic of Xiejiaping Township and Sanzhou Town were successfully detected. The LLR and RR values of the detected aggregation area were relatively large. This combination was the optimal parameter setting. Conclusion The combination of different parameters has a significant impact on the results of spatial-temporal scan statistics. It is recommended that parameters be optimized before applying this method.
