Uveitis is an important autoimmune disease.Human leukocyte antigen (HLA)-B27-associated anterior uveitis is the most common form of anterior uveitis.HLA-B27-associated anterior uveitis has distinct ocular,systemic,and genetic features.It attacks young subjects and leads to the damage of visual function due to the recurrence and complications.However,the pathologic mechanism of HLA-B27-associated anterior uveitis is still not thoroughly understood,and effective therapy is still unavailable.There are currently many experimental researches which attamp to study the etiology and develop an effective therapy for HLA-B27 acute anterior uveitis.Thus,various animal models of acute anterior uveitis such as endotoxin-induced uveitis and HLA-B27 transgenic animals including rat and mouse are established.Different therapy regimens have been designed both in clinical trial and experimental study and aquired promising achievements.Epidemiology,pathologic mechanism,different animal models and potential new therapies such as anti-TNFα,oral associated peptides tolerance and gene therapy are overviewed.

Objective To evaluate application value of plasma tumor type M2 pyruvate kinase (TU M2-PK) in the treatment effect monitoring in breast cancer. Methods TU M2-PK was determined by ELISA in breast cancer patients (n = 63 ), benign breast disease patients (n = 22 ) and health controls (n = 40).The receiver operation characteristic (ROC) analysis was performed as compared with CA15-3 and CEA. Results ROC analysis showed the cut-off was set at 14. 1 U/ml for TU M2-PK ( sensitivity 46. 0% ;specificity 86. 0% ), and the diagnosis efficacy of TU M2-PK was higher than CA15-3 and CEA. The level of TU M2-PK was significantly higher in breast cancer patients (13. 3 U/ml) than that in health controls (7. 2 U/ml, U = 408. 5, P < 0. 05 ) and in benign breast disease patients ( 11.1 U/ml, U = 509.0,P < 0. 05 ). With the progression of breast carcinoma, the level of TU M2-PK as well as the positivity was increased. TU M2-PK concentration was higher in patients with lymph node metastasis (23. 3 U/ml ) than those without metastasis ( 10. 9 U/ml, U = 237. 0, P < 0. 01 ). The level of TU M2-PK correlated with therapy response. An elevated level of TU M2-PK was found preclinically in recurrent disease patients, and the levels decreased in the patients, which showed sensitive to chemotherapy. The TU M2-PK level was kept at baseline in patients with stable disease. Conclusion TU M2-PK is helpful in the diagnosis of breast cancer, and it is a valuable tumor marker for disease monitoring, therapy control and prognosis evaluation in breast cancer.

Objective To determine the aberrant methylation status of TFPI-2,FOXE1 and NPTX2 gene promoter region in bile from cholangiocarcinoma patients and the diagnostic value for cholangiocarcinoma. Methods Methylation—specific PCR(MSP)was used to detect the promoter methylation status of TFPI-2, FOXE1 and NPTX2 genes in bile from 29 patients with cholangiocarcinoma and 27 patients with choledocholi-thiasis.The sensitivity and specificity of combined methylation of 3 promotors and brush cytology were analyzed. Results There was significant difference between the methylation rate of NPTX2,FOXE1 in choledocholithiasis group and cholangiocarcinoma group(75. 86% VS 25. 93%,χ2 = 13. 964,P<0. 05;44. 82%VS 14. 81%,χ2 = 4. 622,P<0. 05).There was no significant difference between the methylation rate of TFPI-2 in choledocholithiasis group and cholangiocarcinoma group(17. 24%VS 18. 52%,χ2 = 0. 016,P>0. 05).Positive rate was 34. 48% with endoscopic retrograde brush cytolog,and 86. 20% with promoter methylation of FOXE1 combined with NPTX2 genes,and there was significance difference in the positive rates between the two methods(χ2 = 14. 122,P< 0. 05). Conclusion The methylation rates of NPTX2,FOXE1 were significantly higher in choledocholithiasis group than those in the cholangiocarcinoma group. Detection of comethylation rate of the FOXE1 and NPTX2 genes could improve diagnostic sensitivity of cholangiocarcinoma.

Objective] To summarize the clinical key points of acupoint sticking therapy in the application of treating disease before its onset. [Method] From the treatment timing, treatment principle, acupoint selection to expound the academic perspective and clinical experience of our department in the application of acupoint sticking therapy by consulting the ancient literature and summarizing clinical practice. [Result] Through the correct selection of treatment timing for acupoint sticking therapy, which is mainly used in summer, secondly used in winter, and focusing on tonifying Yang-qi, and point selection by pattern identification, paying attention to the accumulation of curative effect, this therapy has good curative effect in the treating disease before its onset.[Conclusion] Nowadays, there are more and more sub-health people. Since acupoint sticking therapy has advantages of“easy, convenient, cheap, uesful”and safe, it is a good therapy to apply for treating disease before its onset.

Objective To investigate the clinical significance of kynurenine (KYN) and uric acid (UA) levels in chronic myeloid leukemia patients (CML).Methods 30 CML patients (CML group) and 25 healthy controls (Control group) were enrolled in the hospital from Mar 2014 to Dec 2015.Serum KYN and tryptophan (TRP) of all subjects were determined by high performance liquid chromatography,and KYN/TRP ratio (KTI) were calculated.Leukocytes were counted by automat ic blood cell analyzer.Serum UA were detected by enzyme method.Correlation between UA and KTI,leukocytes were analyzed by Pearson correlation.Results The serum KTI of the CML group (49.76±19.06) before treatment was significantly higher than that of the control group (27.87-±-5.06,t=4.470,P=0.001).KTI cutoff value was 40 by ROC analysis.There had correlation between KTI and leukocytes (r=0.743,P=0.001) and no correlation between KTI and ages (r=0.205,P =0.276).KTI (64.7±17.8) and the leukocytes [(96.7±64.1) × 109/L] of 10 cases of KTI≥40 of CML patients before treatment was significantly higher than that of KTI (27.0± 10.9,t=7.102,P =0.001) and the leukocytes[(10.1 ± 5.2) × 109/L,t=4.285,P=0.002] after treatment.The serum UA in KTI<40 CML patients (n=15,354.98±103.9 μmol/L) was significantly lower than that of KTI≥40 CML group CML (n=15,484.98±132.1 μmol/L,t=1.432,P=0.045).The UA in CML group was associated with KTI (r=0.573,P=0.001) and leukocytes (r=0.537,P=0.002).Conclusion The increase of KTI in CML patients suggested that an increased activity of indoleamine-2,3-dioxygenase (IDO).IDO activity may associated with CML morbidity and therapy effect.The detection of KTI may contribute to the diagnosis of CML and assessing therapy effect of CML.

Obstructive sleep disordered breathing (USDB) is a common diseases which caused by upper airway(UA) occlusion, muscle tone problems and collapse of upper airway etc. The article introduces how to select surgical treatment protocol. First, it is necessary of PSG and upper airway evaluation. Then, it is key to master surgical indications. For the children with hypertrophy of tonsillectomy or adenoidectomy, it may first step of tonsillectomy or adenoidectomy, they needed followed up by orthodontic doctor or orthognathic surgeon for tooth and maxillomandibular malformation. For the adult OSDB patients, there are two method, soft tissue reduction/mass excision around UA or maxillomandibular advancement(MMA), and MMA is recommended to the patients such as failure from UPPP and other surgical treatment, but for severe obesity patients, bariatric surgery is commended, it is very effective for soft tissue reduction around UA and weigh loss. For the OSDB patients with craniaomaxillomandibular deformities, such as craniosynostosis syndrome/micrognathia. Finally, it is important of the UA management for the surgical patients around perioperative period. All in all, it is necessary of the multidisciplinary cooperation for the OSDB patients, surgical treatment is useful method but it is not commend to all OSDB patients.
