[Objective]To explore the operating methods and key points of bysteel-wire guiding fixative steel-wire repearing tibial intercondylar eminence avulsion fractures under arthroscope.[Method]From February 2006 to August 2006,14 patients with tibial intercondylar eminence avulsion fractures were treated in bysteel-wire guiding fixative steel-wire method.Among them,there are 9 males and 5 females with an average age of 32.6 years,aged from 5 to 40 years.Injury cause:7 of road accident,5 of falling down while moving and 2 of falling from height.The results of preoperative x-Ray and Artoscan of all patients suggested the avulsion fracture of anterior cruciate ligament from the tibial spine.In the operation,firstly,fixative steel-wire cross the avulsion fracture tendon-bone joint zone.Then,make each side of avulsion fracture a bone tunnel on the tibial plateau.Finally,guide fixative steel-wire out of these two bone tunnels and then fix this steel-wire with the help of guiding steel-wires.After operation,fix the knee joint with plaster slab bended at 20? in three or four weeks.Remove the plaster slab and do functional exercise after 4 weeks.And move with walking stick 8 weeks later.[Result]All 14 patients were available at follow up with mean duration of 10.5 months.The X-Ray suggested bone healed at about 5.5 months after operation.We got the excellent in 8 cases,good in 4 and fair in 2 according to the advanced Lyshdm's classification at the last follow up.The excellent and good rate was 85.1%.[Conclusion]The technique needn't traditional cut,and has many advantages,such as micro injury,rapid recovery and few complications.And it is good to master the main points of this technique for applying it.

The imaging of X-ray, CT and MRI of 25 cases of limb bone contusion were analyzed retrospectively. Twenty five cases of limb bone confusion were diagnosed by MRI imaging, including 18 cases(72% ) in knee joint,4 cases(16%) in anklebone,2 cases(8%) in wrist and 1 case(4%) in elbow joint. But only 3 cases (12%)presented partial positive results in CT imaging and there was no bone contusion diagnosed. No abnormal manifestation in X-ray imaging for all 25 cases. The results suggest that MRI examination is valuable for diagnose of limb bone contusion.

Objective: To well understand the mental health status and its affecting factors of the residents aged 15 and above of Weihai city. Methods:The sample was randomly chosen by using cluster-based sampling method and was interviewed by using both self-made questionnaire and Kessler 10 rating scale. SPSS was used to analyze the field data.Results:11652 individuals were interviewed, the score distribution in total was 13.3?5.6 and about 22% of them were likely to have a mild or medium or high mental disorder. The factors affecting mental health status were various, not only including general factors such as age, sex, but also other factors such as physical condition.Conclusion:The factors affecting mental health are multiple, about one in five residents are in poor mental status.

Objective To summarize the experience of HIV/AIDS preventive interventions among out-of-school teenagers and provide scientific evidence for the development of large-scale interventions in the future. Method Using both non-random snowball and cluster sampling approach,a total of 5,000 participants were selected from 7 provinces (9 provincial sites ) and a cross-sectional survey was conducted by employing a semi-open-ended self-administrative interview schedule to evaluate their behavioral change before and after the interventions. Results The rate of HIV related knowledge and condom use increased significantly among the participants. For instance,the rate of condom use when having sex at the last time increased by 34.86%,i.e. from 27.67% at the baseline to 59.88% after the intervention (?2=34,86,P

The changes of the hemorheology, plasma cholesterol and albumin and clinicaleffects in 36 children with refractory nephrosis after treatment with polysaccharide sulfate (PSS) were observed. The results showed that the indices of hemorheology and the plasma cholesterol decreased obviously and the albumin increased obviously than the control group ( P

Objective: To investigate the impulsivity of SHR (spontaneous hypertensive rat, the animal model of attention deficit/hyperactivity disorder), and compare it with the WKY (Wistar Kyoto Rats).Method:The experiment was carried on in the standard Campden instrument operant chambers, the animals were 22h deprived of water. A long Variable Interval Schedule was used and the stable documents of the last ten days were analyzed.Result:There was no significant difference of the reinforcement between SHR and WKY rats. The short inter-response times (IRTs) of SHR were much higher than that of WKY rats. There was no significant difference of short IRTs of the two groups among the three same segments of the experiment.Conclusion:The impulsivity of SHR is more obvious than WKY rats. It will be helpful for the biological research of ADHD.

Objective To extract the flavomids from orange peel and determine the content of total flavmoids in orange peel. Methods The total flavonoids in orange peel were determined by using hesperidine as standard sample and edible alcohol as extraction solvent. Results The total content of flavonids is 19.44 g/kg. Conclusion The method is simple and reproducible. It provides a scientific basis for using orange peel.
