Kashin-Beck disease is a chronic, endemic and deformable osteoarthropathy that mainly occurs in children and adolescents in many areas of China, whose main pathological changes are multiple symmetrical degeneration, necrosis, and secondary degeneration of epiphyseal cartilage, epiphyseal plate cartilage and articular cartilage. Patients with Kashin-Beck disease mainly present with joint pain, thickening, deformation, restricted movement, and muscle atrophy. In severe cases, Kashin-Beck disease can cause short fingers, short limbs, and even short deformities. However, there is no specific treatment for Kashin-Beck disease currently. Common treatment methods include non-steroidal anti-inflammatory drugs, cartilage protecting drugs, traditional Chinese medicine, arthroscopy and arthroplasty. This article reviews the treatment methods and research progress of Kashin-Beck disease, aiming to provide a more comprehensive reference for the treatment of Kashin-Beck disease.

AIM:To investigate the effect of atorvastatin on myocardial apoptosis , ventricular remodeling and cardiac function after acute myocardial infarction (AMI) in diabetic rats, and to explore whether the effect is mediated by hepatocyte growth factor ( HGF)/c-Met signaling pathway .METHODS:Diabetes in 70 male SD rats was induced by in-traperitoneal injection of streptozotocin (STZ, 65 mg/kg).After 8 weeks, AMI was induced by the ligation of the left ante-rior descending coronary artery in the diabetic rats , and 32 surviving rats were divided into AMI group (n=16) and AMI+atorvastatin group ( n=16, 20 mg· kg -1 · d-1 ) at random.The similar surgical procedure was completed in sham group (n=11) without coronary ligation.Atorvastatin was given daily by gavage from the first day after AMI .Two weeks later, the cardiac function , pathological changes of myocardial tissues , myocardial apoptosis , and the expression of HGF and c-Met were compared among groups .RESULTS: AMI significantly reduced cardiac function , increased collagen volume fraction ( CVF) and myocardial apoptotic index , and up-regulated the expression of HGF and c-Met at mRNA and protein levels in AMI control group (P<0.05).The cardiac function was improved , and CVF and myocardial apoptotic index were reduced by the treatment with atorvastatin , which also up-regulated the expression of HGF and c-Met (P<0.05).CON-CLUSION:Atorvastatin significantly attenuates myocardial apoptosis and cardiac remodeling , and improves cardiac func-tion after AMI in diabetic rats by further enhancing the activation of HGF /c-Met pathway .

Background and purpose: Sorafenib hepatocellular carcinoma assessment randomized protocol (SHARP) and sorafenib in patients in Asia-Pacific region with hepatocellular carcinoma (ORIENTAL) had indicated that multi-kinase inhibitor sorafenib could prolong overall survival (OS) and time to progression (TTP) as well as improve progress free survival (PFS) in patients with advanced stage hepatocellular carcinoma. Drug-related adverse events in the course of treatment restricted its clinical application to a certain degree. This study was aimed to summerize the adverse events as well as the management of sorafenib in our clinic. Methods: Twenty-five cases clinically diagnosed as advanced hepatocellular carcinoma were enrolled from January 2008 to October 2009. All the patients who received sorafenib treatment met inclusion criteria as followed: (1) Progression of disease after trans-hepatic arterial chemoembolization therapy; (2) Extensive portal vein cancerous thrombus formation; (3) Portal zone or retroperitoneal lymph node metastasis or multiple remote metastasis, such as lung or bone; (4) Diffused poor blood supply to tumor; (5) Inform consent was obtained. All adverse events with different grade were observed during the beginning 12 weeks, and clinical treatment were carried out relatively. Results: Total of 25 cases were enrolled. Nine patients died of the disease, 3 of them died during the first 12 weeks, 3 patients abandoned sorafenib treatment, among them 2 died before the finish of 12 weeks treatment and 1 patient discontinued 5 months after the sorafenib treatment. Twenty cases finally assigned. Number of patients encountered drug-related adverse events were: HFSR (hand-foot-skin-reaction) 4(4/20), diarrhea 4(4/20), alopecia 5(5/20), rasb 4(4/20), fatigue 8(8/20), leukopenia and Thrombocytopenia 4(4/20), elevated blood pressure 1(1/20) and abdominal pain 1(1/20). After clinical management, 20 patients' sorafenib treatment were eventually not affected by adverse events. Conclusion: Sorafenib was well-tolerated and is a safe option of treatment for patients with advanced hepatocellular carcinoma.

Objective To investigate w hether the iterative reconstruction (iDose 4 ) technique improves imaging quality of the low-radiation-dose w hole brain CT perfusion (CTP). Methods Thirty-five consecutive patients w ith clinical y suspected ischemic stroke w ere col ected. Bril iance 256 iCT w as used to perform low-radiation-dose w hole brain CTP, and the filtered back projection (FBP) and iDose 4 algorithm w ere used to conduct image reconstruction. The noise and signal to noise ratio of the 2 kinds of reconstruction algorithms, as w el as the imaging quality of each parameter map w ere compared. Results The effective dose of the w hole brain CTP w as 2.2 mSv. Compared w ith FBP, the noise of each region of interest in the iDose4 Tmax map was decreased significantly ( P<0.05) and the signal to noise ratio was increased significantly (P<0.05). The imaging quality scores (median, interquartile range) reconstructed by FPB group w ere significantly low er than by iDose 4 for cerebral blood flow (CBF) map ( 5.00 [3.00-6.00]vs. 6.00 [5.00-6.00]; Z= -2.784, P=0.005), cerebral blood volume (CBV) map ( 6.00 [5.00-6.00] vs. 6.00 [6.00-7.00]; Z= -3.674, P<0.001), and mean transit time (MTT) map (4.00 [3.00-5.00] vs. 5.00 [4.00-6.00]; Z=3.394, P=0.001). The proportions of the poor quality in CBF map ( 34.3%vs. 11.4%;χ2 =7.036, P=0.030), CBV map (11.4%vs.2.9%; χ2 =7.485, P=0.024 ) and MTT map (28.6%vs.11.4%;χ2 =5.318, P=0.070) reconstructed by FBP w ere significantly higher than by iDose 4 . Conclusions The iDose4 technique may improve imaging quality of low er-radiation-dose CTP.

Objective:To examine the clinical value of combining indocyanine green (ICG) fluorescence navigation with blue dye in sen-tinel lymph node biopsy (SLNB) for patients with breast cancer. Methods:A total of 89 patients with early-stage breast cancer who met the inclusion criteria were admitted at Shantou Central Hospital, Guangdong from May 2013 to April 2014. In phase one, ICG and blue dye were applied in all 53 patients, and then SLNB and axillary lymph node dissection (ALND) were performed based on fluores-cence signal or visual sense of the lymph nodes. In phase two, 36 patients with early-stage breast cancer were included. ALND was omitted when sentinel lymph nodes were frozen showing negative result. Rates of detection, accuracy, and false-negative were calcu-lated. Results:A total of 89 patients were monitored, of which the total rate of SLNB detection was 96.6%(86/89). In the validation pe-riod, the rates of detection, accuracy, and false-negative were 94.3%(50/53) 98.0%(49/50), and 2.6%(1/38), respectively. In the alter-ative period, the rates of detection reached 100%. Of the 196 sentinel lymph nodes, 179 showed fluorescence signal, 142 exhibited blue dying, 54 only demonstrated fluorescence signals, and 45 demonstrated metastasis with five signaling fluorescence. About 24.7%of patients were diagnosed with SLN metastasis (22/89), where SLNB in two patients showed fluorescence signal but without blue dye. No ipsilateral lymph node relapsed were observed during a median follow up of 25 months. Conclusion:Combination of ICG fluores-cence navigation with blue dye in SLNB is safe for patients with breast cancer.

AIM:Tostudywhe ther theangiotens in-(1-7)[Ang-(1-7)]/Mas receptor axis protects cardio-myocytes against high glucose (HG)-induced injury by inhibiting nuclear factor-κB (NF-κB) pathway.METHODS:The cell viability was measured by CCK-8 assay.The intracellular levels of reactive oxygen species ( ROS) were detected by DCFH-DA staining .The number of apoptotic cells was tested by Hoechst 33258 nuclear staining .Mitochondrial membrane potential ( MMP) was examined by JC-1 staining.The levels of NF-κB p65 subunit and cleaved caspase-3 protein were de-termined by Western blotting.RESULTS: Treatment of H9c2 cardiac cells with 35 mmol/L glucose (HG) for 30, 60, 90, 120 and 150 min significantly enhanced the levels of phosphorated ( p) NF-κB p65, peaking at 60 min.Co-treatment of the cells with 1 μmol/L Ang-(1-7) and HG for 60 min attenuated the up-regulation of p-NF-κB p65 induced by HG. Co-treatment of the cells with Ang-(1-7) at concentrations of 0.1~30μmol/L and HG for 24 h inhibited HG-induced cy-totoxicity, evidenced by an increase in cell viability .On the other hand, 1 μmol/L Ang-(1-7) ameliorated HG-induced apoptosis, oxidative stress and mitochondrial damage , indicated by decreases in the number of apoptotic cells , cleaved caspase-3 level, ROS generation and MMP loss .However, the above cardioprotective effects of Ang-(1-7) were markedly blocked by A-779, an antagonist of Ang-(1-7) receptor (Mas receptor).Similarly, co-treatment of H9c2 cardiac cells with 100 μmol/L PDTC ( an inhibitor of NF-κB) and HG for 24 h also obviously reduced the above injuries induced by HG.CONCLUSION:Ang-(1-7)/Mas receptor axis prevents the cardiomyocytes from the HG-induced injury by inhibiting NF-κB pathway .
