Objective To investigate the therapeutic efficacy and side effect of combination of intra-articular injection of hyaluronate and extracorporeal shock wave therapy(ESWT) on patients with knee osteoarthritis.Methods50 patients with knee osteoarthritis were treated by combination of intra-articular injection of hyaluronate and ESWT(study group, n=22) or combination of intra-articular injection of hyaluronate and pain-point injection of betamethasone(control group, n=28). The parameters included pain intensity (Numeric Rating Score, NRS) at rest and at exercise, pain relief rate, the time when pain disappeared and times of betamethasone administration or ESWT. The side effects were also evaluated.ResultsNRS decreased in the two groups after treatment, while NRS was not different between the two groups(P>0.05) except 1 week after the treatment(P<0.01).ConclusionThe combination of intra-articular injection of hyaluronate and extracorporeal shock wave is a safe and effective treatment for knee osteoarthritis.

Nowadays,cerebrovascular disease is one of the main causes of human death.Activation and aggregation of the platelet play core roles in the development of cerebrovascular diseases.A lot of clinical applications have showed that there are great interindividual differences in the response to antiplatelet drugs,and many patients have developed drug resistances.Pharmacogenetic studies have revealed that genetics is one of the key factors resulting in the interindividual differences of the response to antiplatelet drugs.In this overview,the newest advancement in pharmacogenetics is summarized with respect to the antiplatelet drugs.

Objective To investigate the changes of serum and urinary adiponectin (ADPN) levels and insulin resis-tance (IR) states in patients with chronic kidney disease (CKD), and to explore their relationship thereof. Methods A total of 487 patients with CKD stages 2-5 were enrolled in this study, and 30 healthy subjects were served as control group. The se-rum ADPN levels in urine samples were examined by ELISA. The level of fasting insulin (FINS) was detected by radioimmu-noassay. Blood routine test, liver and kidney functions, blood glucose, serum lipids, 24 h urinary protein excretion and endoge-nous creatinine clearance rate (Ccr) and body mass index (BMI) were observed and calculated. The differences of ADPN lev-els in serum and urine samples and homeostasis model assessment for insulin resistance (Homa-IR) were compared between groups. Results The serum and urine ADPN levels and Homa-IR were higher in CKD patients than those of controls (P＜0.05). With the decline in renal function, the ADPN and Homa-IR levels were increased gradually (P＜0.05). The value of se-rum ADPN was significantly higher in patients with CKD stages 3-5 and high Homa-IR. The ADPN levels and Homa-IR were positively related to lipid parameters and 24 h urinary protein, and negatively correlated with hemoglobin and serum al-bumin in patients with CKD (P ＜ 0.05). Conclusion CKD patients had higher ADPN level and more significant IR. The ADPN and IR were correlated with serum lipids, hemoglobin, albumin and urinary protein. Dynamic monitor of ADPN level may have clinical significance in judging metabolic disorders in CKD patients.

Objective:To investigate the clinical features of patients with ankylosing spondylitis ( AS) and malignancies. Methods: In the study, 31 AS patients with malignancies in Peking University First Hospital from January 2006 to July 2014 were enrolled, and their clinical features were compared with AS patients without malignancies at the same time in the hospital. Then their general characteristics, clinical and imaging findings of AS, characteristics of malignancies and prognosis were retrospectively analyzed. Results:The 31 cases of AS with malignacies accounted for 11 . 8% of all AS patients admitted to the hos-pital in the same period. They comprised of 27 males (87%) and 4 females (13%) . Their mean ages at diagnosis of AS were 43 ± 17 years ( range:16-76 years) , and their mean ages at diagnosis of malig-nancy were 60 ± 12 years ( range:31-87 years) respectively. Malignancy was diagnosed after the estab-lishment of AS in 27 of our patients. Furthermore, imaging changes typical of AS were found in all the 31 patients at the diagnosis of AS, but the majority of them had never received any proper treatment for AS. The malignancies of 31 AS patients included bladder cancer (7 cases) , hematological malignancy (6 ca-ses), lung cancer (5 cases), renal cancer (5 cases), prostate cancer (2 cases), carcinoma of renal pelvis (2 cases) , breast cancer (2 cases) , gastric carcinoma (2 cases) , rectal cancer (2 cases) , neu-roendocrine carcinoma (2 cases) , colon carcinoma (1 case) , and esophagus cancer (1 case) . Conclu-sion:There is risk of malignancy in AS. Malignancy is not rare in patients with AS. Bladder cancer is the most common one followed by hematological malignancy. In consequence, close attention should be paied to the conditon of AS with malignancy in clinical practice.

[Objective]To evaluate the clinical treatment results for diastematomyelia treated by operation. [Method]Data from patients with diastematomyelia admitted to our hospital from May 1978 to January 2006 were reviewed. According to the classification, there were single-tube in 25 and double-tube in 96 patients. One hundred and two patients with diastematomyelia were treated by operation and ninteen by conservative treatment. The clinical results were retrospectively analyzed according to scoring neural function and monitoring the peak P40 of posterior trivial nerve cortical somatosensory evoked potential (PTNCSEP) before and after treatment.[Result]The total operative effective rate of double-tube diastematomyelia amounted to 86% during a follow-up period of 6 months to 15 years,more significant in patients with pain.The scores of neural function and PTNCSEP were significantly improved. But patients with single-tube diastematomyelia had no obvious change after operation.[Conclusion]The spinal cord is damaged severely in double-tube diastematomyelia and gradually aggravated.Operation can get symptomatic relief in many patients and terminate spinal cord lesion. So operation should be performed as soon as the diagnosis is made. The spinal cord is damaged slightly in single-tube diastematomyelia and surgery is not indicated.

Objective To study the pathogenesis of nonalcoholic steatohepatitis(NASH) in rat model. Methods Male SD rats were fed with a high fat diet for 12 weeks. Non alcoholic ateatohepatitis serum lipid, aminotransferase values and free fatty acid (FFA) levels were tested, the malondialdehyde (MDA) and superoxide dismutase (SOD) activity of hepatic tissue were also detected. Hepatic cytochrome P450ⅡE 1 (CYPⅡE 1) were detected in liver section by immunohistochemistry using CYPⅡE 1 specific antibodies and also with an immunohistochemical procedure for detecting the number of Kupffer cells. Results FFA concentrations of the serum and hepatic tissue were markedly increased, which was accompanied by an increase of MDA in hepatic tissue, whereas SOD activity of hepatic tissue was decreased. CYPⅡE 1 immunostaining was markedly increased, especially in the perivenous region. The number of Kupffer cells in NASH was significantly increased compared with control livers. Correlation analysis revealed that the increases in the levels of FFA correlated positively with the hepatic CYPⅡE 1 expression, the lipid peroxidation, and the pathological scores in the liver of NASH rats. Conclusion The increased FFA, highly expressed CYPⅡE 1, activated kupffer cells and increased lipid oxidate were all contributed to NASH.

Objective:To evaluate the clinical efficacy of benazepril in combination with valsartan in treating chronic kidney patients with proteinuria and hypertension.Method:75 chronic kidney patients were divided into benazepril group(n=28)and valsartan group(n=26)and combination treatment group(n=21).The changes of 24 hours urinary protein excretion and blood pressure and serum BUN and SCr were observed before the treatment and 4 and 8 weeks after it. Result:The 24 hours urinary protein excretion and blood pressure in all the groups showed significant decreases after the treatment(P0.05),but the levels of SUA were significantly lower in the valsartan group and combination treatment group than those in the benazepril group(P

Objective To investigate the distribution and antibiotic resistance of Mycoplasma isolates from male genitourinary tract infection for rational use of antibiotics to treat Mycoplasma infections.Methods Isolates were detected using Mycoplasma IES Test Kit supplied by Yeoman Biotech (Zhuhai) Co.Ltd.Results A total of 698 strains (30.5%) of Mycoplasma was de- tected from 2 287 samples, 563 (80.7%) of which were Ureaplasma urealyticum, 26(3.7%)were Mycoplasma hominis. Both U.urea lyticum and M.hominis were identified in 109 (15.6%) specimens.U.urealyticum isolates were most suscepti- ble to josamycin, while all M.hominis isolates were susceptible to doxycyeline and minocycline, but resistant to erythromycin, roxithromycin and clarithromycin.Conclusions The best choice to treat Mycoplasma infections is josamycin, doxycycline and minocycline.The different strains of mycoplasrna may have variable susceptibility to the same kind of antibiotic.Active cul- ture, identification, and susceptibility testing of mycoplasma can provide useful data for rational use of antibiotics.

Objective To evaluate the current situation and problems of the application of modified Rankin scale (mRS) in the outcome assessment in Chinese stroke trials. Methods Randomised and quasi-randomised controlled tri?als on stroke therapy published before September 2013 in 3 Chinese databases were included. All clinical trials applied mRS as the method of outcome assessment. Subarachnoid hemorrhage and transient cerebral ischemia were excluded. Types of stroke, statistical methods used for data analysis, duration of follow up, blinding of outcome assessment, types of intervention and the significance of the results were evaluated. Results Two hundred and ninety-eight trials were includ?ed in this analysis. 71.14%was for ischemic stroke, 21.48%for hemorrhagic stroke, 7.38%for both ischemic and hemor?rhagic stroke and 91.28%was for acute stroke(onset time<14d). Regarding to statistical methods used for data analysis, 50.00%of the trials used t-test or variance analysis which treated the mRS score as continuous data, while 22.15%used rank sum test or Chi-square test which regarded the mRS score as ranked data or multiply variable data. Dichotomous data was applied in statistical analysis accounts for 25.50%of trials. 12.42%trials applied mRS with other scales as the methods of outcome assessment. Duration of follow up ranged from 10d to 2 years (median 90 d, interquartile range 30-90 d). Only 5.03%assessed outcome blindly. 60.07%of the trials were drug therapy, 7.72%was rehabilitation thera?py, 10.40%were surgical treatment, 14.43%were combined therapy, 2.35%were management mode, 0.67%were nurs?ing, and 4.36%other therapy. Results in 86.91%of the trials were favorable to the tested interventions. Conclusions In aspects of, there is large difference between domestic and foreign clinical stroke trials in methodology of mRS including duration of follow up, blinding of outcome assessment and statistical methods used for data analysis.
