Objective To study the regulatory effect of interleukin-17 on the production of inflammation and bone erosion related factors of fibroblast-like synoviocytes (FLSs) from rheumatoid arthritis (RA) patients and to investigate whether signal transducer and activator of transcription 3 (STAT3) is implicated in this regulatory effect.Methods FLSs were acquired through primary culture from RA patients.Receptor activator for nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) expression in FLSs were determined using western blot analysis.The level of IL-6,granulocyte-mac rop hage colony stimulating fac tor (GM-CSF)and IL-8 were determined by enzyme linked immunosorbent assay (ELISA) assay.Statistical product and service solutions (SPSS) 17.0 statistical software was used for single factor analysis of variance and LSD-t comparison between each two groups.Results IL-17 stimulated FLSs and promoted the release of IL-6,GM-CSF and IL-8 (t=2.135,P＜0.01) and increased the production of RANKL (t=2.105,P＜0.01) and reduced the production of OPG (t=2.502,P＜0.01).However,targeted silencing of STAT3 could inhibit the effect of IL-17 on FLSs [control group:IL-6 (512±18) pg/ml;GM-CSF (591±25) pg/ml;IL-8 (473±10) pg/ml;RANKL (2.310±0.096);OPG (0.614±0.311);IL-17 group:IL-6 (1 630±39) pg/ml;GM-CSF (1 825±18) pg/ml;IL-8 (2 804±41) pg/ml;RANKL (4.010±0.256);OPG (0.131±0.101);STAT3 silent group:IL-6 (405±21) pg/ml;GM-CSF (451±12) pg/ml;IL-8 (370±9) pg/ml;RANKL (0.850±0.298);OPG (1.120±0.342)].Conclusion STAT3 pathway is critical to IL-17-induced regulatory effect on the release of inflammation and bone erosion related factors of FLSs.IL-17 can induce the inflammation and bone erosion of RA via STAT3.

OBJECTIVE:To improve the work quality in Pharmacy intravenous admixture service(PIVAS). METHODS:The major working links of PIVAS(labeling and drug admixture)were optimized,the work efficiency and error before and after optimi-zation were compared. RESULTS:The work efficiency was improved and error was decreased by adding logo and adjusting work range of personnel when labeling and improving distribution principles of drugs to be allocated in horizontal laminar flow table when drug admixture;compared with before,the labeling time for each bag decreased from(2.69±0.17)s to(2.19±0.08)s,to-tal time for admixture decreased from (104 ± 2) min to (83 ± 2) min,error rate of drug admixture decreased from 0.34% to 0.16%. CONCLUSIONS:The optimized work flow had improved the work quality of PIVAS.

Acute ischemic stroke has become one of the important causes of death and disability in human beings, especially in elderly patients. Intravenous thrombolysis with alteplase is an important treatment. However, there are many underlying diseases and poor overall conditions in elderly patients, which increase the risk of intracranial hemorrhage. Intracranial hemorrhage transformation makes the patient′s condition worse, which is the most serious complication of alteplase intravenous thrombolysis, and also one of the important reasons for the low treatment rate of alteplase intravenous thrombolysis in elderly patients. Therefore, we need to pay close attention to the occurrence mechanism and risk factors of intracranial hemorrhage transformation after alteplase intravenous thrombolysis in elderly patients, so as to reduce the risk of intracranial hemorrhage transformation, improve the prognosis and reduce the risk of morbidity and mortality.

Objective To investigate the clinical characteristics and therapeutic plan of Miller Fisher syn-drome( MFS) complicated with Guillain-Barrésyndrome( GBS) .Methods The clinical data of one patient of MFS complicated with GBS was reviewed retrospectively,and analysis combined with literature review was given.Results The patient had infectious history before the onset of MFS and GBS.Clinical manifestations included MFS triad,bulbar paralysis,bilateral facial paralysis,protein-cell dissociation of cerebrospinal fluid and neurogenic damages in electro-myography.Plasm exchange and adrenocortical hormones treatment were effective.Conclusion MFS complicated with GBS is an independent disease which is different from MFS or GBS.It has its distinct clinical features which should apply appropriate treatment.

Objective To investigate the role and action mechanism of chemokine (C-X-C motif)receptor 3 (CXCR3)in hepatic ische-mia-reperfusion injury (IRI).Methods Forty-eight mice were divided into operation group and sham-operation group.The operation group was treated to establish a mouse model of IRI.Liver tissues were obtained at 3,6,12,and 24 h after IRI,with 6 mice at each time point.The expression of chemokine (C-X-C motif)ligand 9-1 1 (CXCL9-1 1 )and their receptor CXCR3 were measured by real-time PCR and Western blot.The effect of CXCR3 was blocked by its specific antagonist C6.Hepatic injury was estimated based on the activity of hepatic transaminase and morphological indices.The distribution of subsets of infiltrating T cells was analyzed by flow cytometry.All data were expressed as mean ±standard deviation.Comparison between groups was made by one-way analysis of variance.Results Compared with the sham-operation group,the operation group had significantly upregulated expression of CXCL9-1 1 and CXCR3 at all time points after IRI (P<0.05).Blocking CXCR3 significantly protected liver function and morphology (P<0.05).Antagonist C6 significantly re-duced Th1 cell infiltration (P<0.01),but significantly increased Treg infiltration (P<0.01).Conclusion CXCR3 is an ideal therapeu-tic target in IRI treatment due to its relationship with immunoregulation.

Objective To investigate the subthreshold depression for long-term survivors after breast cancer surgery and its effect on their quality of life (QOL). Methods The self-made general questionnaire, Centre for Epidemiological Studies Depression Scale (CES- D), Hamihon Rating Scale for Depression and Functional Assessment of Cancer Therapy- Breast were used to investigate the subthreshold depression and its effect on their QOL for 210 long-term survivors after breast cancer surgery. The difference in general conditions and score of QOL between the subthreshold depression and non-subthreshold depression groups was also compared. Results The subthreshold depression with incidence rate of 46.67%(98/210) was observed for the log-term survivors after breast cancer surgery in this study. The results indicated that the age (≤50) (OR=5.627, 2.662,P<0.01), marriage (unmarried, divorced or widowed) (OR=5.087, P<0.01), employment (unemployed, sick leave or retired) (OR=2.077,P<0.05) and low income (<3000 RMB/month) (OR=3.375,P<0.01) were the key factors that led to the occurrence of subthreshold depression. The score of QOL for the subthreshold depression group were lower than those of the non-subthreshold depression group (t=-6.653--2.926,P<0.01), and had a significantly negative correlation with score of depression and QOL (β=-0.362--0.132). Conclusions A high incidence rate of subthreshold depression for long-term survivors after breast cancer surgery was observed. The incidence rate of subthreshold depression increased for the patients with younger age, low income,unmarried or unemployment. Due to their low QOL, attentions should be paid to the early detection and early prevention for the long-term survivors with subthreshold depression after breast cancer surgery.

Objective To observe the effects of hyperbaric oxygen (HBO) exposure on the expression of aquaporin-1 (AQP1) and aquaporin-5 (AQP5) in rats with simulated high-altitude pulmonary edema (HAPE).Methods Fifty-six rats were randomly divided into five groups:control (normal),HAPE (high altitude pulmonary edema model),1 HBOT (HAPE model and HBO therapy for 1 time),2 HBOT (HAPE model and HBO therapy twice) and NOT (normal pressure oxygen therapy) groups,and was intervened accordingly.Western blotting and real-time PCR techniques were used to analyze the expression of AQP1 and AQP5 in their lungs.The wet-todry (W/D) weight ratio and morphology of the lungs was also examined.Results The protein and gene expression of AQP1 and AQP5 in the HAPE group decreased significantly compared with the control group.There were obvious differences in the protein and mRNA expression of AQP1 and AQP5 between the 2 HBOT group and the HAPE group and between the 2 HBOT group and the 1 HBOT group.Compared with the control group and the 1 HBOT group,marked lung injury could be seen in the HAPE group.Compared with the NOT group and the 1 HBOT group,lung injury in the 2 HBOT group was relieved significantly.Conclusions HAPE in rats is associated with down-regulation of the expression of AQP1 and AQP5 in the lungs.This down-regulation can be attenuated and lung injury can be alleviated by HBOT.Two sessions of HBOT could be more helpful than one for promoting this improvement.

Appendiceal mucinous adenocarcinoma is a rare disease.The preoperative diagnosis is almostly impossible due to the lack of typical symptoms and inexperienced surgeons.One patient with appendiceal mucinous adenocarcinoma was diagnosed successfully at the 210th Hospital of Chinese PLA,who was misdiagnosed as with periappendiceal abscess by other hospitals.The result of intraoperative frozen pathological section confirmed appendiceal mucinous adenocarcinoma.And then the patient received extended resection and effective recovery.
