Objective To screen for differentially expressed proteins in sera from patients with common types of psoriasis,and to identify plasma protein markers for psoriasis.Methods Serum samples were collected from 6 patients with progressive psoriasis vulgaris,5 patients with erythroderma psoriaticum,and 6 healthy human controls,and then pooled into 3 pools:psoriasis vulgaris pool,erythroderma psoriaticum pool and control pool.After removal of high-abundance albumin and IgG,the pooled samples were analyzed by two-dimensional electrophoresis (2-DE).An electrophoretic gel image analysis software was used to locate differentially expressed protein spots followed by peptide mass fingerprinting with matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS).The National Center for Biotechnology Information (NCBI) protein databases were then searched for the identification of differentially expressed proteins.Results All the three pooled serum samples were well seperated by 2-DE.As the gel image analysis software showed,there were 33 protein spots differentially expressed between the patients with psoriasis vulgaris and the healthy controls,17 between the patients with erythroderma psoriaticum and the healthy controls,and 26 between the patients with psoriasis vulgaris and those with erythroderma psoriaticum.Finally,14 proteins were identified as differentially expressed proteins.The patients with psoriasis vulgaris showed higher expression of complement component 3,interleukin-16,vitamin D-binding protein and α1-antitrypsin compared with the healthy controls; the patients with erythroderma psoriaticum showed increased expression of complement component 3,complement component H,α1-antitrypsin,hemopexin and haptoglobin,but decreased expression of serum amyloid protein compared with the healthy controls,as well as enhanced expression of α1-antitrypsin,complement component H,complement component 4 and haptoglobin compared with those with psoriasis vulgaris.Conclusion Differences exist in serum protein profiles between patients with psoriasis vulgaris and erythroderma psoriaticum,and healthy human controls.

BACKGROUND:Knee joint function limitation often occurs after internal fixation of complex femoral condyle fractures, but the mechanism and its influencing factors are also unclear.
OBJECTIVE:To screen and analyze the relevant factors of knee joint function limitation after internal fixation of complex femoral condyle fractures.
METHODS:We retrospectively summarized postoperative fol ow-up data of 6 and 12 months from 121 patients with complex femoral condyle fractures. Knee joint function recovery was evaluated according to Merchan criteria. A multiple stepwise regression analysis was carried out in terms of gender, age, causes, concomitant injuries, skin and soft tissue injury, fracture type, fixed method, operation time, postoperative plaster fixed situation, healing of postoperative incision, bone healing and postoperative functional exercises, to summarize the relevant influencing factors for knee joint function limitation.
RESULTS AND CONCLUSION:Whether the knee joint function after internal fixation was limited acted as the dependent variable Y, and factors with statistical significance of the single factor analysis served as the independent variable X. We used the multiple stepwise regression analysis for multiple factors analysis. Results showed that the gender of patients (X1), with or without concomitant injuries (X3), soft tissue damage (X4) and operation time (X6), a total of four factors, could not be introduced into the model, suggesting that these four factors had no significant correlation with postoperative knee joint function limitation. Another eight factors could be introduced into the factor analysis model, showing that the cause of injury (X2), fracture type (X5), the choice of internal fixation (X7), with or without bone graft (X8), with or without postoperative plaster cast (X9), postoperative knee joint functional exercise or not (X10) and postoperative wound healing (X11), the degree of postoperative bone healing (X12) are closely related to postoperative knee joint function limitation in complex femoral condyles fractures.

Background and purpose. Gastric stromal tumor (GST) is the most common mesenchymal tumor of the gastrointestinal tract and most often arises in the stomach. In the past, surgery was the only effective treatment. The diagnosis and treatment of GST has been revolutionized over the past, since expression of the receptor tyrosine kinase KIT (CD117) was shown to occur on these tumors, the outcome of GST treatment has dramatically been improved. This study focused on the therapeutic experience of GST and analyzed the pathological features and prognostic factors of GST in our center. Methods: All the 26 cases underwent surgical resection and three of them were treated over 6 months with imatinib 400 mg/d. The clinical pathological and follow-up data of 26 patients with GST admitted in our hospital between Jan. 2000 and Dec. 2008 were analyzed retrospectively. Results. All the cases underwent curative resections, including palliative liver resection in 3 patients with liver metastasis. Recurrence occured on 6 patients, including 1 case with low risk group, 1 case with intermediate risk group, 4 cases with high risk group. Tumor size ranged from 2 to 15 cm with the mean of 5.5 cm. The immunohistochemistry results revealed that the positive rates of CD117, CD34 and Vimentin were 92.3%, 80.8% and 96.2% respectively. After operation, three patients accepted imatinib mesylate therapy over 6 months. Two of them were alive, but one had liver metastasis. The follow-up period ranged from 4 to 36 months (median: 28 months). Four cases were lost. The 1-, 3-year overall survival rates of 26 cases were 96.2% and 84.6%. Conclusion: Tumor size, location, mitosis and immunohistochemical data are important variables to evaluate GST behavior and prognosis. Surgical resection is the main therapy for GST and targeted therapy will improve the prognosis.

Objective To compare the effects of application of clavicular hook plate combined with wire anchors anatomical coracoclavicular ligament reconstruction and application of clavicular hook plate in the treatment of NeerII distal clavicle fracture and Tossy Ⅲtype~V acromioclavicular joint dislocation. Methods A retrospective analysis of the clinical data from June 2006 to June 2013. Total 73 cases patients suffered with Neer Ⅱtype distal clavicle fractures and Tossy Ⅲtype~V acromioclavicular joint dislocation. Of which , 41 cases were subjected to treatment with clavicular hook plate , 32 patients subjected to treatment of using clavicular hook plate combined with anchors .The incision length, operative time, postoperative complications, length of hospital stay and postoperative 1 month, 6 month shoulder VAS score of two groups were analyzed; the shoulder function of both groups after 1 month, 6 months were assessed by using Constant shoulder function assessment method. Results Surgical incision length and operational time between the two groups were statistically significant (P<0.05), while the amount of bleeding was not statistically significant. All patients were followed up . The two groups did not occur any complications such as loosening, decoupling, acromioclavicular joint dislocation and wound infections. Hospitalization time was 5~14 d (averaged 10d), no significant difference between two groups. 4 the shoulder Constant score and VAS scores showed no significant difference 1 months postoperation; 6 months after hook plate removed, VAS score and Constant shoulder score improved significantly in anchors hook plate group (P<0.05). Conclusion Anatomical coracoclavicular ligament reconstruction by application of hook plate combined with anchors is a good biomechanical model characterized with simple surgery , less trauma and good clinical outcomes , worthy of clinical application.

BACKGROUND:Vertebroplasty with bone cement injection can achieve a correction of kyphosis, enhancement of vertebral strength, and elimination of vertebral lesions during reduction of the fracture. OBJECTIVE: To analyze the efficacy of vertebroplasty with bone cement injection on osteoporotic vertebral compression fracture. METHODS:Totaly 84 patients with osteoporotic thoracolumbar vertebral compression fractures (T6-L4), 37 males and 47 females, aged 58-80 years, were randomized into two groups: study group undergoing vertebroplasty with bone cement injection and control group subject to bed rest and conservative treatment (functional exercise of the back muscle). Visual analog scale score, Oswestry disability index and vertebral height were detected and compared between the two groups before and after treatment. RESULTS AND CONCLUSION:There was no difference in vertebral height, visual analog scale score and Oswestry disability index between the two groups before treatment. At 3 months after treatment, the vertebral height was (1.653±0.168) cm in the study group and (1.521±0.200) cm in the control group, with a significant difference (P< 0.05). The visual analog scale scores and Oswestry disability index scores in the study group were both lower than those in the control group at 3 months after treatment and at the last folow-up (P < 0.05). After treatment, there were two cases of pressure sores, three cases of deep venous thrombosis, one case of pneumonia and two cases of urinary tract infections in the control group; while only 4 cases developed bone cement leakage in the study group, but with no obvious clinical symptoms. No difference in re-fracture rate occurred between the control group (n=3) and study group (n=4;P > 0.05). These findings suggest that the bone cement injection as vertebral augmentation therapy can rapidly relieve pain, improve patients' quality of life within a short term and restore the vertebral height in patients with osteoporotic vertebral compression fractures.

Objective To compare the quality of life ( QOL) in different family life cycle residents and analyze its influencing factors. Methods Based on the stratified cluster sampling,517 married residents from three communities of Dongguan city were chosen to be investigated by a questionnaire on the general status and the MOS health survey (SF-36).The One-Way ANOVA and Multiple Regression Analysis were used to analyze the data. Result There were significant differences on the seven domains of the SF-36 ex-cept of physical pain in different family life cycle residents (P<0.05) . The scores of different domains at the retirement or senior years were the lowest ( ranging from 37.10-59.81) ,and the scores of different domains at the child-bearing period were highest (ranging from 37.10-59.81). The results of Multiple Linear Stepwise Regression showed that the QOL of different family life cycle residents were influenced by some factors. The influencing factors on PCS at the child-bearing period were income (β=1.51) and life events (β=-6.13), while that at the period of families with adolescents were economic income (β=1.81) and age (β=-0.65);that at the period of empty nest were economic income (β=-3.64) and age (β=-0.65);and that at the re-tirement or senior years were unhealthy living habit (β=-15.06),age (β=-0.56) and income (β=3.06). The influencing factors on MCS at the child-bearing period was medical insurance (β=5.86),while that at the period of families with adolescents were medical insurance (β=6.28),education (β=2.32),life events (β=-4.68) and occupation (β=-5.53);that at the period of the empty nest were age (β=-0.61) ,gender (β=-10.35) and chronic disease (β=-8.35);that at the retirement or senior years were age (β=-0.27) , economic income (β=2.55) and unhealthy living habit (β=-6.95) . Conclusion The influencing factors of QOL for different family cycle residents are not conformity with each other. It suggested that in order to im-prove the QOL of residents, the community health service including health education and health promotion should be based on different family life cycle.
