Refractory nephrotic syndrome(RNS) is one of the main causes of end-stage renal disease (ESRD) in children,which is also a difficult issue in clinic.Several therapies,including immunosuppressive agents,have been shown to be effective and safe for RNS.It is proved,however,that a substantial number of children are still refractory to treatment despite these therapies.Recently,rituximab as a new immunosuppressant has achieved good results for RNS,and a number of case reports and clinical trials have suggested that rituximab may be effective for children with RNS.This review will analyse the scientific basis for the efficacy and safety of using rituximab in children with RNS.

Acute kidney injury (AKI)was a common problem in children in clinic.pRIFLE Criteria, AKIN Criteria, KDIGO Criteria are the main classification criteria of AKI.Though serum creatinine is still used as the most common biomarkers for diagnosis of AKI, the sensitivity and specificity is unsatisfactory.In recent years, many potential biomarkers of AKI have been studied in a variety of experimental and clinical settings.This review describes the novel biomarkers of AKI, including cystatin C, neutrophil gelatinase associated lipocalin, interleukin-18 ,kidney injury molecule-1 and liver-type fatty acid binding protein,, which have now made a progress in clinic.

The Wireless Body Area Network (WBAN) is a key part of the wearable monitoring technologies, which has many communication technologies to choose from, like Bluetooth, ZigBee, Ultra Wideband, and Wireless Human Body Communication (WHBC). As for the WHBC developed in recent years, it is worthy to be further studied. The WHBC has a strong momentum of growth and a natural advantage in the formation of WBAN. In this paper, we first briefly describe the technical background of WHBC, then introduce theoretical model of human-channel communication and digital transmission machine based on human channel. And finally we analyze various of the interference of the WHBC and show the AFH (Adaptive Frequency Hopping) technology which can effectively deal with the interference.

Subclinical hypothyroidism is common in children,but its clinical significance is widely debated.The pathogenesis is not very clear and etiology appears to be multifactorial,such as autoimmune thyroiditis,obesity,antiepileptic drugs and so on.Currently there is no broad consensus on the management of children with subclinical hypothyroidism.In this review,the available evidences regarding to investigation,risk factors,trreatments and outcomes for this disease are summarized.

Objective To study the treatment influences on immunity and tumor recurrence of oral canc -er patients with the combination therapy of hyperbaric oxygen treatment and postoperative adjuvant chemotherapy . Methods In the period from March 2011 to March 2014 ,84 patients were clearly diagnosed with oral cancer and randomly divided into hyperbaric oxygen treatment combined postoperative adjuvant chemotherapy group ( group A,n=42)and postoperative adjuvant chemotherapy group (group B,n=42).From day 1 prior to the last day of chemotherapy ,patients in group A were treated with hyperbaric oxygen ,and patients in group B were just accepted chemotherapy.After chemotherapy,we tested the levels of CD3 +,CD4 +,CD8 +and NK cells by flow cytometry, and the expression of IL -2,IL-4,IL-10 and INF-γby ELISA essay.All patients had been followed for two years.Results The levels of CD4 +and NK cells in group A were higher than group B (P<0.05),but the levels of CD3 +and CD8 +between the two groups were obviously different (P>0.05).Compared with group B,the ratio of CD4 +and CD8 +was increased in group A(P<0.05).The levels of cytokines involved IL -2,IL-4,IL-10 and INF-γin group A were higher than the levels of group B ( P<0 .05 ) .Follow-up results showed that pa-tients treated with hyperbaric oxygen combined postoperative adjuvant chemotherapy had less recurrence in 2 years(P<0.05).Conclusion Hyperbaric oxygen combined postoperative adjuvant chemotherapy can improve the patients′immune function ,and to be effective in preventing two years′recurrence .

Objective To evaluate the effect of probucol on endothelium-dependent vasodilatation(i,e.flow- mediated dilation,FMD) function of the old patients with isolated systolic hypertension.Methods In this single- blind study,a total of 64 old pariems with isolated systolic hypertension were randomized to receive conventional an- tihypertensive therapy and probucol (0.5g twice daily,group A,n=33) or receive conventional antihyperrensive therapy(group B,n=31) for 12 weeks.The levels of blood lipid were measured and vascular endothelial function was assessed in the brachial artery by high-resolution ultrasound technique in form of endothelium-dependent vasodi- latation before and after treatment.Results After 12-week treatment,the levels of TC,LDL-C and HDL-C in group A were significantly reduced compared with those before treatment(all P0.05).Flow-mediated dilatation parameters in both groups were obviously improved compared with those before treatment( P

[Objective]To evaluate the therapeutic effect of arthroscopic treatment for osteoarthritis of the knee,and explore the factors related to clinical outcome. [Methods]Three hundred and sixty-two patients with knee osteoarthritis were treated by arthroscopic surgery in the 88th hospital from May 2000 to November 2007. Of them,124 patients were followed-up completely. Quantified clinical data were input into computer and analyzed statistically by SPSS 16.0 software. Lysholm score was used to evaluate the therapeutic effect. Lysholm scores before surgery and at follow up were compared with paired t test. Patients were divided into different subgroups according to sex,locking,X -ray grade,arthroscopic grade and surgical methods. Lysholm scores at the final follow up of different subgroups were compared with variance analysis. The factors related to operation outcome were explored by using multiple stepwise linear regression analysis.[Results]One hundred and twenty-four patients were followed up from 7 to 96 months with an average of 39.6 months. Preoperative Lysholm score was (46.10?2.80),the score at follow up was (70.69+2.90),there was significant difference between preoperative score and at follow up (t=9.362,P0.05). The difference was significant between groups whether locking or not (F=10.654,P

[Objective]To explore the effects of joint synovial fluid on tendon-bone healing of reconstructed ligament. [Methods]Forty female New Zealand rabbits,aged 6 months,weight 2.5~3.5 kg,were divided into 4 groups randomly.Transfer of semitendinosus tendon to the bone tunnels was performed to make bone-tendon healing model,on the right knee the bone tunnel was not communicated to the joint cavity,in contrast,the bone tunnel on the left knee was connected with synovial fluid.Animals in one group were killed at 8 weeks after operation,bone-tendon healing samples were harvested for biomechanical test.Animals in other three groups were killed at 2,4 and 8 weeks after operation respectively to harvest the samples for histological observation.HE and Masson staining were conducted to examinant histological change.[Results]At 2 weeks after operation,there was no significant difference between non joint synovial fluid group and joint synovial fluid group in bone-tendon interface healing,which were filled with granulation tissue.At 4 weeks postoperatively,interface healing in non joint synovial fluid group was obvious better than that in joint synovial fluid group.Fibroblast cells and cartilage cells increased obviously,and collagen fibers synthesized.At 8 weeks after operation,tendon-bone interface in joint synovial fluid group was filled with connective tissue,the collagen fibers arranged disorderly.In contrast,more compact collagen fibers were seen in non joint synovial fluid group.Interface cell accounts in non joint synovial fluid group were superior to that in joint synovial fluid group at 2,4,8 weeks after operation (P
