Objective To describe an alternative procedure of arthroscopic double-bundle posterior cruciate ligament (PCL)reconstruction using deep-frozen fresh allogenic achilles tendon and evaluate the follow-up outcome in early stage. Methods The ruptured PCL was reconstructed under arthroscopy using deep frozen fresh allogenic achilles tendon preparing in Y-shaped allografts, one bundle was used for anterolateral bundle, the other for posteromedial bundle. Absorbable screw was used to fix the soft tendon graft and metal screw was used to fix the bone graft. Results From March 2003 to August 2004, the procedure of arthroscopic double-bundle PCL reconstruction using allogenic achilles tendon was applied in 10 cases. The average follow-up period was 13.2 months(6~24 months, among them 6 cases were more than 12 months ). 2 cases with anterior cruciate ligament (ACL) injury were also reconstructed with hamstring tendons (semitendinosus and gracilis). 3 cases with rupture of postolateral horn of knee joint were anatomically reconstructed with hamstring tendons. Clinical results were carefully compared using the Lysholm score system before and after the operation, the average score was 50.3 preoperatively, and 91.2 postoperatively. The objective examination showed that the tibia post-migrating sign, posterior drawer test and Lachman test were positive in all the 10 cases preoperatively; whereas the posterior drawer test and Lachman test were negative postoperatively; the tibia post-migrating sign were weak positive in 3 cases with longer clinical histories(more than 1 year); the flexion range of the knee were slightly restricted (5?~20?) in the 2 cases with simultaneous ACL injury. Conclusions Allogenic achilles tendon is an ideal material for arthroscopic double-bundle PCL reconstruction. Arthroscopic double-bundle reconstructed PCL is in accordance with the anatomy and physiology of natural PCL. The injury and complications caused by the autograft can be alleviated. The allograft can be prepared in advance and the soft end of the implant can pass through the bone tunnel easily, and thus the operaton time under arthroscopy can be saved and the trauma caused by arthroscopy is abated. Arthroscopic double-bundle PCL reconstruction is sample, safe and effective.

Objective To introduce the method of two bundle anatomical reconstruction of the posterolateral corner(PLC) of the knee using auto-harmstring,and to evaluate the short-term clinical outcomes.Methods Using auto-harmstring,23 knees of 21 cases with acute or chronic posterolateral complex injuries were anatomically reconstructed from March 2003 to November 2005.There were 20 male and 1 female patients(mean age:32.3 years,ranging from 17 to 47 years)in this study with follow-up of at least 12 months(average:26.7 months,ranging from 12 to 31 months.Tow cases had isolated PLC injuries,21 knees had multiligamentous injuries,and 5 cases associated with meniscus injuries.The technique used includes:(1)an autogenous semitendinosus placed through trastibial bone tunnel from posterior to anterior and then turned to transfibulur bone tunnel to reconstruct the popliteus and popliteofibular ligament;(2)an autogenous gracilis tendon placed through transfibulur bone tunnel to reconstruct the fibulocolateral ligament(FCL).The transplanted grafts were secured to the femoral insertion of the popliteus and FCL respectively with metal or bioabsorbable interference screw.All patients were followed-up prospectively with clinical examinations and Lysholm knee scores.Results There was no varus knee instability in full extension,and one-grade varus instability with firm endpoint was found in 2 cases at 30? flexion.There was no increased external rotation in all of the 23 knees at 30? flexions(in prone position).Mean Lysholm knee scores were 89.2(range from 88 to 100).Conclusions Two bundle anatomical reconstruction of the PLC of the knee using auto-harmstring yields a stable knee with excellent function,mini-trauma,and reliable fixation of grafts,this technique is an ideal method for the treatment of PLC injuries.

Three antibodies were used for immunohistochemical study of 15 cases of adenoid cystic carcinoma(6 cases contained normal salivary gland tissue). The results indicated that myoepithelial cell of the normal salivary glands revealed positive reaction of S-100 protein; The basal cells of the straited ducts and excretary ducts revcaled strong positive reaction of keratin. In adenoid cystic carcinoma positive reaction of S-100 prctein and vimentin were found in luminal cells of cribriform pseudocyts and peripheral cells of tumor nests, and the outer layers'cells of tubular stucture and the border cells of trabucula. But the positive reaction of keratin was found in inner cells of tubular and central cells of trabecular patten. It indicated that adenoid cystic carcinoma probably stems from the basic cells of the striated ducts and excretary ducts of normal salivary glands.

[Objective]To explore LIU Wansu's methods in treating fire and heat disease from depression of yang qi.[Methods]To analyse LIU Wansu's understanding of fire and heat disease and highlight its treatment from depression of yang qi through reading his works like Exploration to Pathogenesis in Plain Questions,Yellow Emperor's Plain Questions on Xuanminglun Formulae and so on.[Results]LIU Wansu had profound medical knowledge,rich clinical experience and initiative spirit.Under the guidance of nineteen items of pathogenesis from Huangdi's Canon of Medicine,he expanded fire and heat disease and put up six exogenous pathogenic factors can transfer to fire theory.To be specific,excessive wind,cold,dampness and dryness would block Xuan Fu and depress yang qi,causing fire and heat disease.He regardeddepression of yang qi as a key link in six exogenous pathogenic factors' transferring to fire and put up cooling combined with ventilating method to dissipate depressed yang qi,including relieving exterior syndrome with pungent-cool drugs,clearing depressed heat,relieving exterior and interior syndrome,eliminating dampness and relieving depression as well as combination of cold and warm drugs.[Conclusion]LIU Wansu treated fire and heat disease from depression of yang qi,providing new methods in treating fire and heat disease for later generations as well as guiding significance in current clinical work.

At present the most common colorimetry for the activity determination of the peroxidase ( POD) is based on the detection of the absorbance of product at 470 nm in a reaction system of the H2 O2/POD/guaiacol ( GA) , but the shortcoming of the method is that the formed product is not stable and there is the serious adsorption phenomenon on the cell. To solve this problem, a new method was established for accurate determination of POD activity based on the fluorescent feature of GA. By using standard solutions of horseradish peroxidase as the test samples and under these optimum conditions such as 0. 5 mmol/L of GA, 0. 5 mmol/L of H2 O2 , pH 6, 0. 05 mol/L of phosphate buffer solution and the reaction temperature of 20℃, the sample volume was only consumed 20 microlitre at a time, the linear response range was 500-60000 U/L ( r=0 . 9993 ) , the detection limit was 385 U/L and relative standard deviation was ≤2 . 4% ( n=11 ) . The comparisons for the determination results of the POD activity in the white radish’s extraction solutions were conducted among our method (9714±132 U/L) and the colorimetric method (9926±352 U/L) as well as the recirculating-catalytic flow analysis ( 9608±456 U/L ) . The results showed that the mutual consistency is better.

[ Abstract] Vitamin D is a steroid derivative. It has the effect of regulating calcium -phosphorus metabolism. With the development of medicine, the effects of vitamin D in other respects, such as regulation of blood pressure, blood glucose, nerve protection, and immunity have received more and more attention. A lot of research show s that the level of vitamin D is closely associated w ith the onset and outcome of ischemic stroke. In addition, some researchers explored the relationship betw een vitamin D and stroke from the genetic perspective. How ever, the existing research results are not consistent. The link betw een vitamin D and ischemic stroke is not clear. This article review s the correlation studies of the relationship among vitamin D and vitamin D receptor gene polymorphism, the onset of ischemic stroke, outcomes and risk factors in recent years.
