Systemic juvenile idiopathic arthritis (sJIA) is a systemic inflammatory disease characterized with arthritis in one or more joints,fever,rash and serositis.Due to the atypical symptoms and poor prognosis,it's a great challenge in the clinical diagnosis and treatment efficacy evaluation in sJIA.These challenges could be addressed by the identification of clinical biomarkers,aiming at evaluating the disease severity,predicting the activity and prognosis of sJIA.This review will be focus on genetics,serum and cellular markers in sJIA and summarize the relative application on diagnosis and treatment.

Objective To observe clinical effects of Sanqi wound tablets combing with Western medicine to conservative treatment of acute thalamic hemorrhage.Methods72 patients with acute thalamic hemorrhage from Department of Neurosurgery from December 2014-June 2016 were grouped two groups by random number table method.The control group was treated with Western medicine, and observation group was treated with Sanqi wound tablets combing with Western medicine.Relevant indicators were analyzed between two groups.ResultsEffective rate of observation group was 88.89%, higher than control group with 69.44%(P<0.05).NSE and hs-CRP level of observation group were (7.02±1.86)μg/L,(11.75±2.64)mg/L, lower than control group(13.98±2.01)g/L,(19.82±3.07)mg/L(all P<0.05).Fugl-Meyer and NIHSS of observation group were (93.07±4.25),(12.01±2.30)points, better than control group(81.16±4.10),(18.42±2.45)points(all P<0.05).Thalamic residual bleeding of observation group was (2.82±0.41)mL, lower than control group (3.97±0.57)mL(P<0.05).ConclusionOn the basis of Western medicine, Sanqi wound tablets can improve the therapeutic effect, reduce inflammation, improve the patient's motor function and nerve defect degree and accelerate the absorption of hematoma.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%～84% similarity, and yeast 80%～92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.

Programmed cell death 5(PDCD5)is a new kind of programmed cell death regulation and control gene. PDCD5′s expression is widespread,and evolution is conservative. PDCD5 has the effect of promo-ting a wide variety of tumor cells to apoptosis and inhibiting proliferation,such as lung cancer,liver cancer et al. Several laboratories′ discoveries show that PDCD5′s expression is significantly decreased when in some dis-ease cases,especially in tumor cases. PDCD5,which is related to the clinical relevance of the tumor,has a great clinical value of discovering,diagnosis and treatment of the tumor.

Objective To discuss the clinical efficacy of internal fixation assisted by thoracoscope in treatment of rib fractures.Methods The study enrolled 180 patients with rib fractures associated with thoracic deformity hospitalized from July 2010 to June 2013.Ninety out of the patients were operated on by thoracoscope-assisted internal fixation (operation group),and the remaining 90 fractures were treated non-operatively (non-operation group).Clinical markers recorded were duration of pain,time of ventilator use,hospital length of stay and complications.Patient mental health was measured with self esteem scale (SES).Patient mobility was evaluated at follow-up.Results Between operation and non-operation groups differences were observed in duration of pain [(3.1 ± 1.0)d vs (8.9 ± 1.2) d],time of ventilator use [(3.0 ± 1.0) d vs (4.8 ± 1.0) d] and hospital length of stay [(10.0 ± 1.1) d vs (15.8 ± 1.0) d] (P ＜ 0.01).SES in operation group was (28.3 ± 2.1) versus (24.4 ± 3.3) points in non-operation group (P ＜ 0.01).No major complications occurred in operation group,but there were 20 pleural effusion,15 severe thoracic collapse or deformity,14 lung infection,10 refractory chest pain and 2 upper limb dysfunction in non-operation group (P ＜0.01).Two patients presented mobility limitation in operation group,but 12 had evident loss of mobility in non-operation group (P ＜0.01).Conclusions Thoracoscope-assisted internal fixation is effective to accelerate the pace of recovery,relieve pains,reduce complications and thus can be a priority method for treatment of rib fractures.

Research on osteoporosis diagnosis has always been a critical isuue in the field of international academia and medicine. Recent progress in quantitative ultrasound (QUS) has suggested that ultrasound, due to its obvious advantages, be considered as an effective and noninvasive tool for assessment of bone status and diagnosis of osteoporosis. This paper presents the principle and recent development in the ultrasonic assessment of bone status and osteoporosis including assessment with through-transmission and backscattering measurement, and also introduces the latest progress in ultrasonic axial transmission technique.Limitations of current research are discussed and suggestions are proposed for future research.

Objective By comparing the physiological index and diosgenin content of rhizome between the artificial tetraploid and the wild type diploid of Dioscorea zingiberensis, it is aimed at revealing the potential utility of polyploid breeding in medicinal D. zingiberensis. Methods Three clones of the natural diploid and the artificially induced tetraploid of D. zingiberensis were used as materials in this study. The content of SOD, PPO, and soluble sugar of leaves was determined by spectrophotometry, CAT content was measured by using the method of KMnO_4 titration. And the diosgenin content in rhizome was analyzed by HPLC. Results The tetraploid plants showed higher level of SOD, PPO, CAT, soluble sugar content in leaves, and diosgenin content in rhizome than those of the diploid origins. The diosgenin content in the three clones of tetraploid plants increased to 27% as compared to wild type. Conclusion Artificially induced tetraploid presents high content of diosgenin and great potential in stress resistance, which would be available in good seed breeding for high yield of diosgenin.

Circulating DNA is cell-free DNA existing in plasma or serum. It has already been verified that circulating DNA of cancer patients is derived from tumor cells. Therefore, it is of great value to detect the changes in the quantity and quality of the circulating DNA in cancer patients for early diagnosis and prognosis. The advantages of the detection of circulating DNA such as micro-trauma, convenient access to samples, possibility of continuous and dynamic monitoring, make it a promising tumor mark. This review recapitulates the application of circulating DNA analysis in hepatocellular carcinoma patients for diagnosis and prognosis.

Aim Toinvestigatetheroleofbrain-de-rived neurotrophic factor(BDNF)-tyrosine receptor ki-nase B (trkB ) signaling pathway in the therapeutic effects of ketamine on diabetic neuropathic pain.Meth-ods Forty-eightWistarrats,aged3months,weighing 200~250 g,were equally randomized into 4 groups(n=12 ):control group (C group ), saline group (S group),ketamine group (K group)and ketamine +ANA-12 group (KA group ).Rats in S,K and KA groups were intraperitoneally injected with a single of streptozotocin(STZ)65 mg·kg-1 to construct diabetic neuropathic pain model.After twenty-eight days,rats in S,K and KA groups were intraperitoneally injected with saline, ketamine 10 mg·kg-1 and ketamine 10 mg·kg-1 +ANA-12 0. 5 mg·kg-1 for consecutive 7 days, respectively. On the 8th day, mechanical withdrawal threshold(MWT)of rats was measured.Af-ter that,the rats were immediately sacrificed,and dor-sal ganglion of lumbar spine and prefrontal cortex (PFC)were harvested for measuring BDNF,p-trkB/trkB,synaptophysin and spine density by Western blot andglogistaining.Results ComparedwithCgroup, rats in S group significantly decreased MWT,BDNF, p-trkB/trkB,synaptophysin and spine density in dorsal ganglion and PFC (P <0. 05 ).Compared with S group,rats in K group showed a significant increase of MWT,BDNF,p-trkB/trkB,synaptophysin and spine density in the all observed regions(P<0. 05 ).On the contrary,rats in KA group showed a significant de-crease of MWT and BDNF,p-trkB/trkB,synaptophys-in and spine density as compared with K group in all regions(P<0. 05 ).Furthermore,BDNF was positive-ly correlated with spine density in all regions (P <0.05).Conclusion BDNF-trkBsignalingpathway mediates ketamine-induced therapeutic effects in dia-betic neuropathic pain.
