The JAK/STAT pathway contributes to control gene expression,cell growth,proliferation,differentiation,apoptosis and immunoregulation.Recent studies have found that the JAK/STAT pathway was closely related to the occurrence and development of lymphoid neoplasms.The study of JAK/STAT pathway could lead to new treatment strategies for lymphoid neoplasm treatment.

Objective To investigate the effect of integrated traditional Chinese and western medicine in the treatment of postoperative pain in patients with anorectal diseases. Methods From November 2015 to October 2017, 70 patients with anorectal diseases underwent surgical treatment in the First People 's Hospital of Yongkang were selected. The simple western medicine treatment was performed in 35 patients with anorectal diseases in the control group,and 35 patients in the observation group were given combined Chinese and western medicine. The total effective rate of the two groups was observed and calculated. The pain score at 2 h,6 h,12 h and 24 h after operation,the incidence rate of postoperative complications were observed. Results The total effective rate of the control group (80. 00％ ) was lower than that of the observation group (97. 14％ ),the difference was statistically significant(χ2 =5. 080,P < 0. 05). The pain scores at postoperative 2h,6h,12h,24h in the control group were (2. 0 ± 0. 5) points, (3. 6 ± 1. 0)points,(4. 5 ± 1. 0)points,(5. 0 ± 1. 2)points,respectively,which in the observation group were (1. 4 ± 0. 2)points,(2. 0 ± 0. 6)points,(2. 4 ± 0. 5)points,(2. 3 ± 0. 4)points,respectively,the differences were statistically significant(t = 6. 591,8. 116,11. 112,8. 116,all P < 0. 05). The incidence rate of postoperative complications in the control group (17. 14％ ) was higher than that in the observation group (2. 86％ ),the difference was statistically significant(χ2 = 3. 968,P < 0. 05). The total satisfaction rate of the control group (74. 29％ ) was lower than that of the observation group (94. 29％ ),the difference was statistically significant(χ2 = 5. 285,P < 0. 05). Conclusion The combination of traditional Chinese and western medicine is effective in the treatment of postoperative pain in patients with anorectal diseases,which can increase the effective rate and improve the quality of life of the patients, and it is worthy of clinical application.

Objective To observe the level of serum hepcidin and the relationship of hepcidin with renal anemia and micro-inflammation state in peritoneal dialysis(PD) patients.Methods Serum hepcidin,interleukin-6(IL-6),soluble transferrin receptor (sTfR) and erythropoietin (EPO) were measured in 50 PD patients with anemia,30 PD patients without anemia and 40 cases of normal control by ELISA.The indexes of blood routine examination,biochemistry and iron metabolism were also detected at the same time.Results The level of hepcidin in PD patients was significantly higher than that in normal control[(103.65±43.6) μg/L vs (56.39±35.7) μg/L,P ＜ 0.05].Furthermore,the level of hepcidin in PD patients with anemia was higher than that in PD patients without anemia [(122.67±36.6) μg/L vs (83.65±26.4) μg/L,P ＜ 0.05].The results of correlation analysis showed that serum IL-6,sTfR,EPO and ferritin were positively correlated with hepcidin(R =0.821,0.742,0.711,0.531,all P ＜ 0.05),while creatinine clearance of residual kidney in 24 hours and hemoglobin were negatively correlated with hepcidin(R =-0.533,-0.685,all P ＜ 0.05).Conclusions The higher level of hepcidin in PD patients is related with the residual renal function and the micro-inflammatory state.The higher level of hepcidin may induce the iron metabolism imbalance,and then influence the state of renal anemia.The adjustment of hepcidin may provide clinical research value of improving renal anemia and micro-inflammatory state in PD patients.

Objective:To describe the expression profiling of microRNAs of patients with non-small cell lung cancer. Methods:We reduced the scope of downregulated microRNAs in patients with non-small lung cancer by high throughput microarray based on quantitative real-time PCR (qRT-PCR). In this process, the downregulated microRNAs of non-small cell lung cancer tissues can be de-tected and compared with adjacent healthy lung tissues with relatively small samples. Different microRNA expression levels in non-small cell lung cancer and adjacent healthy lung tissues were verified in a large sample by RT-PCR. Results:A total of 20 types of microRNAs were significantly downregulated in non-small cell lung cancer tissues compared with adjacent healthy lung tissues. These microRNAs were listed as follows: hsa-miR-1; hsa-miR-22; hsa-miR-27a; hsa-miR-27b; hsa-miR-125a-5p; hsa-miR-125b;hsa-miR-142-5p;hsa-miR-143;hsa-miR-148a;hsa-miR-148b;hsa-miR-370;hsa-miR-373;hsa-miR-381;hsa-miR-489;hsa-miR-519a;hsa-miR-376c;hsa-miR-206;hsa-miR-380-5p;hsa-miR-223-5p;and hsa-miR-520c-3p. Among these microRNAs, 13 types were down-regulated in non-small cell lung cancer tissues as verified by RTPCR. These 13 types of microRNAs were listed as follows:hsa-miR-125a-5p; hsa-miR-143; hsa-miR-519a; hsa-miR-223-5p; hsa-miR-1; hsa-miR-520c-3p; hsa-miR-489; hsa-miR-27a;hsa-miR-373; hsa-miR-125b; hsa-miR-27b; hsa-miR-142-5p; and hsa-miR-206. Conclusion: In non-small lung cancer tissue, several kinds of microRNAs were significantly downregulated. Changes in microRNA expressions were significantly associated with tumori-genesis, progression, or other cancer cell functions in non-small cell lung cancer.

Objective To explore the effect of pre-filled catheter flushing device on the sealing of venous indwelling needle. Methods One hundred and sixteen patients with venous indwelling needle were assigned into observation group, in which pre-filled catheter flushing device was used to seal the needle tube and another 109 with venous indwelling needle as control group, in which the needle tube was sealed with 50U/mL heparin saline.The two groups were compared in terms of blockage of the tube, phlebitis, catheter-associated infection, indwelling time of the needle and time for nurses to seal it.Results The rates of blockage of catheter, phlebitis and catheter-associated infection of the observation group were all lower than those of the control group.The indwelling time of the needle was significantly longer than that in the control group.The time for nurses to seal the catheter was significantly shorter than that in the control group(all P<0.05). Conclusion Pre-filled catheter flushing device can reduce complication rate and improve working efficiency of nurses.

Ewing's sarcoma is a kind of bone and soft tissue tumor which is highly invasive and mainly occurres in children and adolescents.In recent years,combined chemotherapy,surgery and radiation therapy in treatment of Ewing's sarcoma,patients' prognosis and life quality have been significantly improved.However,over the past 20 years,the treatment of Ewing's sarcoma entered the platform period.The 5-year overall survival rate remained at 55％-75％.Multiple metastasis and recurrence are the main factors of poor prognosis and death.Chemotherapy,radiotherapy and molecular targeted therapy are still the main methods for the treatment of Ewing sarcoma.The side effects,drug resistance and the use of the combination regimen of antitumor drugs have been plaguing the clinical workers.In order to improve the efficacy of chemotherapy drugs and reduce the toxic side effects,Multi-disciplinary and multi-center clinical studies on Ewing's sarcoma patients who suffered from local control or recurrence have been launched by Domestic and European and American countries.As an important supplementary mean for the treatment of Ewing's sarcoma,patients often appear a series of complications after radiotherapy,including the risk of local damage or secondary tumors.Therefore,it is necessary to further clarify the indications of radiotherapy and the timing of preoperative and postoperative radiotherapy.The specific chromosome translocation and the expression of the fusion gene EWS/FLI 1 have been found in Ewing sarcoma.Nevertheless,the mechanisms that drive tumor relapse and metastasis remain unknown.Molecular targeted therapy can be used to inhibit tumorigenesis and progression by regulating the upstream or downstream target genes of EWS/ FLI1.In conclusion understanding of the current treatment status of Ewing's sarcoma,results of multi-center clinical trials and theory of genomics research will contribute to the design of new biological therapies so as to establish individualized treatment modalities.In this paper,we present a review on the progress of Ewing sarcoma chemotherapy,radiotherapy,molecular targeted therapy and immunotherapy.
