Objective To investigate the histological changes and collagen phenotype of a semitendinosus autograft after reconstruction of posterior cruciate ligament(PCL) in rabbits. Methods Twenty skeletally mature New Zealand white rabbits were divided into two groups. In group 1, the PCL of the right knees of 18 mature New Zealand white rabbits were resected and immediaterly reconstructed with double-band semitendinosus antograft. Then the rabbits were respectively killed at 3, 6, 12, 26 and 52 weeks after the operation, to obtain the the semitendinosus autografts. Group 2 consisting of the other 2 rabbits was served as control group, and semitendinosus tendons and PCL were obtained. All specimens were staining with hematoxylin and eosin, toluidine blue and immunohistochemical methods of type Ⅰ, Ⅲ collagens to analyze the histological changes and collagen phenotype of a semitendinosus autograft, and compare those with normal semitendinosus tendons and PCL. Results Histological results demonstrated that there was obvious difference at the cell formation between normal semitendinosus tendon and PCL. After postoperative 52 weeks the graft was similar to the normal PCL, while the alignment of graft was still different from that of normal PCL through necrosis, cell growing in, collagen formation and remolding. Immunohistochemistry result demonstrated: the staining of type Ⅰ collagen in graft was low at first, then increased gradually; the staining of type Ⅲ collagen was low at first, increased quickly, then decreased, at 52 weeks it was present in local areas. But positive reactions for type Ⅰ collagen were localized in collagen fibers, and those for type Ⅲ collagen were localized in synovium in normal PCL. Conclusion The study showed the semitendinosus autograft was still different in cell formation from normal PCL at 52 weeks after PCL reconstruction with semitendinosus.

Objective:The purpose of this paper is to illustrate different diseases that cause this crazy-paving pattern and to correlate the thin-section CT findings with the histopathological findings. Methods: A retrospective review of the medical records of our radiological computed tomography database was performed from January 2010 until December 2012,searching for patients reported to have a crazy-paving pattern on a thin-section CT of the chest. In total, 83 patients with a crazy-paving pattern were retained and reviewed. Results:The crazy-paving pattern consists of interlobular septal and intralobular interstitial thickening superimposed on an area of ground-glass attenuation on thin-section CT scans. We identified 83 cases that presented with the crazy-paving pattern, inclould infection(bacterial infection n=6,viral infection n=16,fungal infection n=1,and mixed infection n=12); ARDS n=4; acute pulmonary oedema n=3; interstitial lung disease (UIP, NSIP) n=18; adenocarcinomas n=3; lymphangitis carcinomatosis n=3;lymphoma pulmonary infiltration n=2;radiation pneumonitis n=5;sarcoidosis n=1;alveolar proteinosis n=4;alveolar hemorrhage n=4; lipid pneumonia n=1. Conclusion: The crazy-paving pattern on thin-section CT is a non-specific signs, can be seen in infections, tumor, as well as some cryptogenetic diseases. Nevertheless, familiar with these common diseases, allows us to narrow the differential diagnosis, even prompted the diagnosis of certain diseases in the appropriate clinical setting.

Objective To study the injury mechanism, diagnosis and therapy of traumatic dislocation of the peroneal tendons. Methods 18 cases with traumatic dislocation of the peroneal tendons were operated in our institute from 1986 to 2000. The mechanism of injury and clinical findings were investigated. 2 cases with acute dislocation were operated by suturing the peroneal retinaculum directly. 16 cases with recurrent dislocation were treated with Watson-Jones operation. Results 10 cases with recurrent dislocation were follow-up from 1 year to 15 years with an average of 6.2 years. Only one recurrence due to ankle sprain was found and the other 9 cases had no more dislocation and returned to sports without symptom.Conclusion Traumatic dislocation of the peroneal tendons can be caused by the injury of ankle joint in three positions:dorsiflexsion and eversion, dorsiflexsion and inversion, plantflexsion and inversion. Anti-resistant test of dorsiflexsion and eversion may help diagnosis. Watson-Jones operation has the advantages of simple to apply, minor trauma and sound clinical outcome.

Objective To explore the expressions of endoplasmic reticulum stress (ERs) related factors including inositol requiring enzyme-1α(IRE1αα),p-IRE1 α,c-jun N-terminal Kinase(JNK),and p-JNK in rats with non-alcoholic fatty liver disease,and to investigate the effect of intervention with glucagon-like peptide 1 (GLP-1) analogue.Methods Forty male Sprague-Dawley rats were divided into normal chow group(n =15) and high-fat diet group(n=25).After 12 weeks,5 rats of each group were used to assess the establishment of rat models with non-alcoholic fatty liver disease.Then the high-fat diet group rats were divided into high-fat diet group (HF,n =10) and GLP-1 group(HG,n=10) and treated with normal saline and GLP-1 analogue for4 weeks respectively.Body weight and biochemical markers in rats were measured.The expressions of IRE1α,p-IRE1α,JNK,and p-JNK were measured by Western blot.Results Compared with the NC group,the levels of body weight,plasma triglyceride (TG),total cholesterol (TC),low density lipoprotein-cholesterol (LDL-C),alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in HF group were significantly higher (all P ＜ 0.01),high density lipoprotein-cholesterol(HDL-C) was decreased(P＜0.01),and p-IRE1 α/IRE1 α and p-JNK/JNK were increased(P＜0.05 and P＜0.01).After GLP-1 treatment,body weight,plasma TG,TC,LDL-C,AST,ALT in HF group were significantly lowered(P＜0.05 or P＜0.01),HDL-C was increased(P＜0.01),p-IRE1 α/IRE1 α and p-JNK/JNK were decreased (P＜0.05 and P＜0.01).Conclusion GLP-1 analogue may improve hepatic steatosis via regulating ERs related IRE1 α-JNK signaling pathway.

OBJECTIVETo investigate the clinical efficacy of Panlongqi tablet (Chinese characters) combined with lumbar facet joint release for lumbar spinal stenosis of type Fengshi Bizu (Chinese characters).

METHODSSince February 2012 to February 2013, 120 patients with lumbar spinal stenosis of Fengshi Bizu (Chinese characters) syndrome were retrospectively studied. According to different treatment methods, 120 patients with lumbar spinal stenosis were divided into Panlongqi tablet (Chinese characters)group and control groups, respectively. In Panlongqi tablet (Chinese characters)group, 60 patients were treated by Panlongqi tablet (Chinese characters) combined with lumbar facet joints release solution including 26 males and 34 females with an average age of (60.40±3.36) years old ranging from 46 to 65 ; the course of the disease was 2 to 15 years (averaged 7.6 years). In control group the other 60 patients were treated with lumbar facet joint release including 24 males and 36 females with an average age of (61.20±2.47) years old ranging from 48 to 63; the course was 3 to 14 years (averaged 6.9 years). The clinical effect of patients were evaluated by JOA and ODI score before treatment, at 4 weeks and 3 months after treatment.

RESULTSAll patients were followed up for 4 to 7 months (means 5.6 months). After 3 months,7 cases in control group recurrenced symptoms,only 1 case in Panlongqi tablet (Chinese characters) group recurrenced. At 4 weeks and 3 months of follow-up, ODI score and JOA score of Panlongqi tablet group were much better than those of the control group.
