Abstract： Objective　To analyze the changes of cytokine levels in patients with sensitive pulmonary tuberculosis and drug-resistant pulmonary tuberculosis before and after anti-tuberculosis treatment. Methods　The clinical data of 213 pulmonary tuberculosis patients admitted to the Eighth Affiliated Hospital of Xinjiang Medical University from August 2019 to October 2020 were collected, and divided into a sensitive pulmonary tuberculosis group and a drug-resistant pulmonary tuberculosis group, of which 141 were in the sensitive group and 72 in the drug-resistant group , and the pro-inflammatory factors tumor necrosis factor-α (TNF-α), IL-6, IL-17, interferon-γ (IFN-γ) and anti-inflammatory factors IL-10 and IL-4 in plasma before treatment, 3 months and 6 months after treatment were compared. Results　Compared with the healthy group, the levels of plasma IL-6 in the sensitive group and the resistant group were significantly increased, difference was statistically significant (P<0.01). The plasma levels of IFN-γ and IL-17 in the sensitive group were increased, and the difference was statistically significant (P<0.05). Compared with before treatment, the levels of IL-6 and IL-4 in the plasma of the sensitive group after 6 months of treatment were lower than those after 3 months of treatment, and the difference was statistically significant (P<0.05), and IFN-γ was significantly decreased (P<0.001). After 6 months of treatment, the IL-10 content was lower than that before treatment, and the difference was statistically significant (P<0.05), and the IFN-γ decreased significantly (P<0.000 1). The levels of IFN-γ at 3 months were higher than those in the resistant group, and the difference was statistically significant (P<0.01). After 6 months of treatment, there was no significant difference in the content of IFN-γ between the sensitive group and the resistant group. The effective rate of CT absorption was 70% in the sensitive group and only 43.33% in the resistant group at 3 months of treatment, and there was no significant difference in the effective rate between the two groups after 6 months of treatment. Conclusions　Detection of pro-inflammatory cytokines and anti-inflammatory cytokines in plasma can provide reference for host-directed therapy of pulmonary tuberculosis. Understanding this important feature of cytokines on pathogen-host interactions can provide new insights into the study of virulence mechanisms and may provide new approaches for immune intervention in pulmonary tuberculosis.

[Objective] To observe the effect of Leweiyin of traditional Chinese compounds prescription on gastrointestinal hormones and oxygen free radicals in IBS rabbits of spleen deficiency,and to explore the possible mechanism for the treatment of IBS with spleen deficiency.[Methods] 36 two-month-old rabbits with white feather and black eyes(WHBE rabbit),half male and half female,were randomly divided into 6 groups:normal group,model group,Xiangsha Liujun pill group,Lizhu Changle group,low-dose Leweiyin-treated group,high-dose Leweiyin-treated group.Except the normal group,others were made into IBS model of spleen deficiency which was induced by damp heat stress and gavage with Fanxieye as well as method of either hunger or gorge.The drug groups were administered preventively from the medium-term of the model reproduction to the end of modeling.The rabbits of each group were observed.NO,NOS,MDA,SOD in serum and SP in colonic membrane were detected.[Results] NO,NOS,MDA in serum and SP in colonic membrane significantly more increased than the normal group(P

AIM: Firstly to evaluate the changes of corneal sensation and its effect to dry eye syndrome after laser in situ keratomileusis (LASIK); secondly to evaluate the relation between the changes of corneal sensation and the laser ablation depth. ·METHODS: 30 patients (60 eyes) had bilateral LASIK with a superior-hinged flap. Every patient underwent preoperative and postoperative (after one week, one month and three months) evaluations, including corneal sensation, Schirmer's basic tear secretion test, tear breakup time (TBUT), corneal fluorescein stainting, and a questionnaire evaluating dry eye obtained from each patient.·RESULTS: Compared with preoperative level, after one week and one month, the difference of corneal sensation was very significant (P＜ 0.01); after three months, there was no statistical difference (P ＞ 0.05). After one week, there was no statistical difference (P ＞ 0.05) in the subjective dry eye symptoms, after one month, the difference was significant(P=0.025 ＜0.05) and after three months, the difference was very significant (P=0.001 ＜ 0.01). Compared with preoperative level, the basic tear secretion decreased significantly after one week and one month(P＜ 0.01), it did not return to the baseline level after three months (P ＜ 0.01). Tear breakup time decreased significantly after the surgery, and after three months, there was still statistical difference compared with preoperative level (P ＜ 0.01); with cornea fluorescence staining, we found corneal epithelial defect was most serious after one month after LASIK, and did not return to the baseline level after three months (P ＜ 0.01). Linear regression analysis and relevant were used to evaluate the relation between the changes of corneal sensation and the laser ablation depth (r=0.798, P ＜ 0.01). ·CONCLUSION: The central corneal sesation decreased noticeable after LASIK, and it recovered three months postoperatively, but the indicators of dry eye syndrome did not return to their preoperative levels following it. We have found that the decreasation of corneal sensation had positive correlation with the laser ablation depth.

ObjectiveTo explore whether the biocompatibility of phosphorylcholine (PC) modified alginate-chitosan microcapsules could be improved. MethodsPC modified alginate-chitosan microcapsules were obtained by high-voltage electrostatic system.Bradford method was adopted to determine the adsorption amounts of bovine serum albumin by chitosan alone and PC modified chitosan.Alginate-chitosan-PC microcapsules (experimental group) and alginate-chitosan microcapsules ( control group) were respectively implanted into the peritoneal cavity of mice and retrieved 4 weeks after transplantation.Fibrosis of the capsules was evaluated by HE staining.Glucose stimulated insulin secretion (GSIS) assay was used to assess the insulin secretion response of encapsulated and nonencapsulated rat islets. Results The adsorption amount of protein was 189.4 μg/mg and 90.5 μg/mg respectively by chitosan alone and PC modified chitosan.The difference had statistical significance ( t =5.549, P ＜ 0.05 ).In contrast to the control group, the cellular reaction on the surface of the modified microcapsules was weaker, with no obvious fibrosis found.The insulin secreted by encapsulated islets and nonencapsulated islets was( 3.298 ± 1.680 ) μIU/ml VS (4.299 ± 1.159 ) μIU/ml ( t =1.096, P ＞ 0.05 ) in response to low-glucose stimulus and( 11.783 ± 4.175 ) μIU/ml VS ( 12.875 ± 2.268 ) μIU/ml ( t =0.514, P ＞ 0.05 ) in response to high-glucose stimulus.Conclusions PC can improve the biocompatibility of alginate-chitosan microcapsules, with no effect on the biological function of encapsulated islets.It may be more appropriate to use modified microcapsules encapsulating islets for transplantation.

Objective To investigate the relationship between the echinoderm microtubule associated protein like 4-anaplastic lymphoma kinase (EML4-ALK) and epithelial growth factor receptor (EGFR) mutation status and overall survival (OS) in Uygur patients with stageⅣnon-small cell lung cancer (NSCLC) who did not accept tyrosine kinase inhibitor treat-ment. Methods Totally 97 tissue samples were collected from Uygur patients with stageⅣNSCLC who did not accept tyro-sine kinase inhibitor treatment. EML4-ALK fusion gene and EGFR mutation status were detected by using FISH and ARMS methods. The survival rates were analysed. Results In 97 tissue samples, EML4-ALK fusion genes were found in 6 (6.2%) samples, EGFR mutations were found in 26 (26.8%) samples. The survival analysis showed that there was no significant dif-ference in OS between EML4-ALK fusion gene group and no EML4-ALK fusion gene group (P=0.941). There was no signifi-cant difference in OS between EGFR mutation group and wild-type EGFR group (P=0.607). The values of median OS were 17.7 months, 17.3 months and 16.2 months for EGFR mutant group, EML4-ALK positive group and EML4-ALK negative+EGFR wild-type group, and thre was no significant difference between them (P=0.915). Conclusion Excluding the thera-peutic influence in TKIs, EML4-ALK fusion gene and EGFR mutation status of tumor tissue can not be used as an indepen-dent factor in assessing the prognosis in Uygur patients with stageⅣNSCLC.

Objective To prepare monoclonal antibody against Prostate Stem Cell Antigen(PSCA) and explore the inhibitory effects of Anti-PSCA mAb in treatments of human prostate cancer xenografts in mice. Methods Balb/c mice were immunized by PC-3 cell line. After fusing and screening, the anti-PSCA McAb’s characterizations were determined. Solid tumors in mice were produced by subcutaneous injection with PC-3 cells in the flanks of the mice.We picked out 10 mice bearing human prostate cancer xenografts.They were divided into a treatment group (n_1=5) and a control group (n_2=5).200 ?g Anti-PSCA mAb was injected into abdominal cavity of each mouse of the treatment group and PBS for them of the control group.Anti-PSCA mAb and PBS were administered once every three days for consecutive three times.The mice survival conditions of two groups were recorded during 5 weeks.The serum PSA, the tumor weights and dimensions of survived mice were measured.The tumor volume inhibition rate was calculated. T-test was performed to compare differences of PSA in serum,tumor weights and volumes between the treatment and control groups.Routine pathological slides of tumor tissue were observed under light microscope to evaluate the range of tumor tissues damaged by Anti-PSCA mAb. Ultrastructure was observed with transmission electron microscope. Results A marine McAb was produced, which raised against PSCA,belonged to IgG1 subclass. The average PSA serum level of the two groups were(3.28?0.55)ng/ml and(7.26?0.43)ng/ml.The weights of tumors of the two groups were(0.95?0.17)g and(3.08?0.18)g.The volumes of them were(164.59?14.08)mm3 and(548.49?19.79)mm3.There are remarkable differences between the treatment group and the control group(P

The factors influencing cost accounting fall into such three categories as drivers and incentives,factors affecting authenticity and accuracy,and factors affecting application and selection.DRG payment,as it is getting more popular than before,is pushing forward cost accounting at an unprecedented pace.Thanks to the current payment system reform and the transition of public hospital reimbursement regime,such needs as exact payment,j ust compensation and cost/performance management of such hospitals are challenging the present cost accounting system,calling for the birth of a cost accounting system for these hospitals.To build such a system,micro-and macro-level goals need to be considered simultaneously,while needs of different levels should be designed,integrated and interacted with each other.Only in this way,goals can be reached for such a system.
