Objective To determine the monokine levels of serum and synovial fluid (SF) in patients with JSpAs and estimate the correlation between monokines and inflammatory indices.Methods Serum and SF monokines (IL 1?,IL 1?,IL 6,IL 8,IL 12 and TNF ?) were measured by sandwich ELISA in patients with JSpAs ( n =28) and healthy controls ( n =10).The correlation between serum monokines and inflammatory indeces and between both serum and SF monokine levels was analysed.Results Elevated serum level of IL 6 was found in patients with JSpAs as compared to healthy controls ( P

0.05). Removal of two thirds or the entire horizontal portion of the TFCC caused a statistically significant difference in the percentage of force transmitted through the ulna compared with the intact force data (t=3.4,P

Objective To investigate the dynamic variation of subsets of myeloid derived suppressor cells (MDSC) and their ratio in septic mice, and to discuss their role in the development of sepsis. Methods Male C57BL/6 mice were randomly divided into sepsis model group and sham group according to random number table. Polymicrobial sepsis was induced by using cecal ligation and puncture (CLP), while mice in sham group only underwent laparotomy and laparorrhaphy without CLP. Thirty mice in each group were used to observe living condition, and the 20-day survival rate was compared between the two groups. In addition, subsets of MDSC in peripheral blood, spleen and bone marrow were analyzed with flow cytometry for other 60 mice (12 mice at each time point, as 0, 3, 7, 12 and 20 days). Spleens were harvested at 7 days for weighing, and single cell suspension of spleen tissue was prepared for splenocyte counting. Histopathologic changes in spleen tissue and liver tissue were observed under light microscope after hematoxylin and eosin (HE) stain. Results ① No mice died in sham group within 20 days after the operation. On the other hand, 10 mice in model group died within 20 days, and the difference in survival rate between the two groups was statistically significant (100.0% vs. 66.7%, χ2 = 11.861, P = 0.001). ② The spleens in model group showed obvious enlargement and significantly outweighed as compared with those in sham group (mg: 413.33±41.63 vs. 111.67±17.56, t = 11.564, P = 0.000), and the total count of splenocytes was significantly higher than that in sham group (×109/L: 21.20±2.43 vs. 1.87±0.06, t = 13.578, P = 0.005). ③ Pathological sections with HE staining showed that the liver tissue and spleen tissue remained normal in sham group. In model group, the hepatic tissue showed acute inflammatory reaction, including tissue disruption, capillary congestion, infiltration of neutrophils, marked edema of hepatocytes and focal hepatocellular necrosis. Abnormalities were also found in the spleen tissue: the red pulp and white pulp were disordered, splenic sinus was congested with numerous red cells, the splenic capsule thickened, immature myeloid cells with circular nuclei proliferated in the subcapsular region and perivascular region, splenic cord and splenic sinus were infiltrated with a large number of hematopoietic cells. ④ No significant changes in the monocytic MDSC (M-MDSC) and granulocytic MDSC (G-MDSC), and their ratio were found in peripheral blood, spleen and bone marrow at every time point in sham group. On the other hand, in model group, the ratio of M-MDSC and G-MDSC was continuously increased in peripheral blood, spleen and bone marrow, and M-MDSC only slightly decreased at 20 days. On the other hand, the ratio of M-MDSC/G-MDSC rose at first followed by a decrease. The ratio of M-MDSC/G-MDSC in peripheral blood was higher than 1 from 3 days after the operation, reaching the peak at 12 days (compared with 0 day: 4.16±0.53 vs. 0.79±0.11, P < 0.05), while the ratio of M-MDSC/G-MDSC in spleen and bone marrow after CLP were lower than 1 at all time points, reaching the peak on 7 days after the operation (compared with 0 day: 0.70±0.06 vs. 0.25±0.02 in spleen, 0.39±0.06 vs. 0.11±0.01 in bone marrow, both P < 0.05), and then gradually decreased afterwards. Conclusion Subgroups of MDSCs were continuously aggregated in the peripheral blood, spleen and bone marrow, and their ratio rose first and decreased afterwards along with the development of sepsis, and the changes may reflect the change of immune status at different stages of sepsis.

Objective To explore the characteristics of sleep disturbance and its related factors in patients with rheumatoid arthritis (RA).Methods A total of 71 patients with RA in Department of Rheumatology Huaxi Hospital have completed the following questionnaires, including Pittsburgh sleeping quality index (PSQI), visual analogue scale (VAS), disease activity score in 28 joints (DAS28), health assessment questionnaire (HAQ), hospital anxiety and depression scale (HADS), fatigue severity scale (FSS) and a self-designed general status questionnaire.Results The prevalence of sleep disturbance was 42.3％ (30/71) in rheumatoid arthritis patients (68.4％).The scores of DAS28, VAS, PSQI, HAQ, FSS and HADS in patients with sleep disturbance were significantly higher than those in patients with good sleep, which were respectively 3.90 ± 1.12 vs 2.92 ± 1.92, (5.03 ± 2.63) scores vs (2.41 ± 1.84) scores, (10.87 ± 2.42) scores vs (4.29 ± 1.85) scores, 3.0 (0.0, 7.0) scores vs 2.0 (0.5,4.0) scores, (39.17 ±14.02) scores vs (29.63 ± 16.12) scores, (14.50 ±7.77) scores vs (9.49 ±6.57) scores (P ＜ 0.05 in all scales).According to the results of Pearson correlation analysis, PSQI had significantly positive correlation with DAS28 (r =0.462, P ＜ 0.01), VAS (r =0.556, P ＜ 0.01), HAQ (r =0.360, P ＜ 0.01), FSS(r =0.420, P ＜ 0.01) and HADS (r =0.447, P ＜ 0.01) respectively.The logistic regression analysis indicated that VAS was a predictor for poor sleep quality (P ＜ 0.01).The patients receiving biological agents had significantly (P ＜ 0.05) lower scores of DAS28 (2.86±1.39 vs 3.52 ± 1.1 0), PSQI [(5.90 ± 4.24) scores vs (8.53 ± 3.78) scores], VAS(2.15 ± 2.30 vs 4.05 ± 2.46), HAQ [0.0 (0.0, 2.0) scores vs 3.0(0.0,6.0) scores] compared to those taking oral drugs.Conclusion High prevalence of sleep disturbance in patients with RA is noted, which indirectly influences the activity of disease, quality of life, depression, fatigue and other physical and mental health.Biological agents can partly improve the sleep disturbance and functional status.

Objective To explore the effect of online health education by family physician using the wearable devices, and provide the basis in theory and practice to improve the level of primary health care in community. Methods A total of 132 community residents (78 for male and 36 for female, all of them are WeChat user) with hypertension in one residential area who had regularly participated in the activity of volunteer blood pressure measurement organized by community health service center in wujiaochang street from November 2015 to February were chosen as the participants. The residents who wore the wearable device given by the community hospital uniformly were set as the study group (60 people), while the remaining 72 residents were set as the control group. Both groups received the daily online health education provided by the family physicians through their smartphone. We compared the diversity of health cognition, controlling behavior and controlling results to blood pressure of both groups before and after the studyrelatively, then we comprehensively analyzed the effect of use of wearable devices in family physicians ' online health education. SPSS 18.0 was used for data analysis. The categorical data of two groups were compared with chi-square test and the comparison of continuous data was performed with t test. Results Totally 114 community residents were qualified in the study, and the initial backgrounds of study group and control group had no significant difference. After receiving the online health education information for three months, both groups achieved improvement on the cognition and related self-control behavior of hypertension except for several items, and the study group did better than control group in most items. The physical examination showed that the systolic blood pressure of the study group after the intervention [(131.46 ± 12.89) mmHg] (1 mmHg=0.133 kPa) was lower than before [(137.24 ± 12.27) mmHg] and the difference was significant (t=9.2, P<0.01); the diastolic blood pressure of the study group after the intervention [(78.29±8.91) mmHg] was lower than that of before intervention [(80.75±10.25) mmHg] and the difference was significant (t=2.3, P<0.05). Meanwhile, after intervention the systolic blood pressure of study group [(131.46 ± 12.89) mmHg] was lower than that of control group [(133.27 ± 12.7) mmHg] and the intervention was significant (t=2.1, P<0.05). Conclusion Long-term use of wearable devices help family physicians improve the effect of health education, consequently the community hospitals are responsible to enhance the input and management of the informatization of family physicians' service, and assist them to broaden the form and content of health education.

Objective To study the protein expression levels of matrix metalloproteinases (MMPs)and their inhibitors in bone tissues of rat femoral head and to explore the relationship between necrosis of femoral head and glucocorticoid.Methods Twenty healthy adult SD rats were randomly divided into glucocorticoid group and control group,with 10 rats in each.Glucocorticoid group was treated with intramuscular injection of hydrocortisone twice a week.The control group received normal saline of the same volume.Four weeks later,bone tissues of left femoral head were collected from each group of rats for HE determination of femoral head necrosis.The expressions of matrix metalloproteinase-1 (MMP-1 ), matrix metalloproteinase-2 (MMP-2 ), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1 ),and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2 )at mRNA and protein levels were detected by RT-PCR and Western blot techniques,respectively.Results The expressions of MMP-1 and MMP-2 at mRNA and protein levels were higher in glucocorticoid group than those in the control group. However,TIMP-1 and TIMP-2 gene and protein expression levels were lower in glucocorticoid group (all P<0.05). Conclusion The expressions of MMPs in bone tissues of rat femoral head in early necrosis were increased,but their inhibitors had decreased expressions. We can draw the conclusion that glucocorticoid-induced necrosis of femoral head may be related to its regulation of the expression levels of MMPs and their related inhibitors.

Objective To explore the influence factors of hidden blood loss during the treatment of femoral intertrochanteric fractures with percutaneous compression plate( PCCP) in elder patient. Methods The data of 136 patients with intertrochanteric fracture in our hos-pital from March 2009 to March 2012 treated with percutaneous compression plate were retrospectively analyzed,the effect of age,fracture type,preoperative aspirin,internal diseases on perioperative hidden blood loss, and different haemoglobin ( HGB) levels in patients with dif-ferent distribution were analyzed. Results The mean hidden blood loss volume was 499 mL,which accounted for 92. 54% of the total blood loss. The mean HGB decline was 11 g/L. The rate of on admisson haemoglobin level lower than 80 g/L was 6. 62% in AO type A2. 3 and A3 groups,and the rate of postoperative haemoglobin level lower than 80 g/L was 14. 70%. The average hidden blood loss for AO type A2. 3 (862 mL) and A3 (698 mL) were higher than those for AO types A1 (430 mL),A2. 1 (450 mL) and A2. 2 (415 mL) (P<0. 05). Multi-variate linear regression analysis showed that comminuted fracture and preoperative aspirin treatment were independently associated with in-creased perioperative hidden blood loss. Conclusion It indicated that the overt blood loss was fewer for PCCP operation. Intertrochanteric fracture was the main reason for substantial perioperative hidden blood loss. Types A2. 3 and A3 intertrochanteric fracture were early predic-tive factors of postoperative haemoglobin level lower than 80 g/L in elderly patients.

Objective To investigate the efficacy of endoscopic intranasal structure reconstruction surgery for rhinogenous headache. Methods 82 cases of rhinogenous headache were given endoscopic intranasal structure reconstruction. Compared VAS scores before and 6 months after treatment, counted the effective rate. Results Among the 82 patients, 69 patients(84. 1%) were cured, 8 cases (9. 8%) were of obvious effect, 5 cases (6. 1%) were invalid, and the total efficiency was 93. 9%. VAS scores of the mucosal contact headache group before treatment were greater than that of the sinus headache group (P<0. 05). Compared with VAS scores before treatment, both of the two groups had lower VAS scores after treatment (P<0. 05), but there was no significant difference between the two groups after treat-ment (P>0. 05). Conclusion Endoscopic surgical operation can remove the extrusion of the nasal cavity and paranasal sinuses and factors of nasal congestion, and then reconstruct normal anatomical structure of nasal cavity, thus restoring normal function of paranasal sinuses. It has good therapeutic effect on rhinogenic headache.

Objective To compare the difference in cardiac injuries between asphyxia and ventricular fibrillation modes in different periods after cardiac arrest (CA).Methods The model was established in Cardiopulmonary Resuscitation Lab,Sun Yat-sen University.A total of 35 male SD rats were used to produce the asphyxia or ventricular fibrillation (VF) cardiac arrest models randomly.Both of the two modes were induced 8 minutes cardiac arrest.The myocardial HE stains,mitochondrial respiratory control ratio (RCR),and echocardiography were observed at 4 h,24 h and 72 h after ROSC (restoration of spontaneous circulation).The results were expressed as (-x ± s),t test was performed to compare between two groups,and one way analysis of variance was used to compare multiple groups.P ＜ 0.05 was considered as significant difference.Results HE stains showed damages were more serious in the VF mode than in asphyxia mode at 4 h,and both of them had a disorderly-arranged myocardium at 72 h.RCR in VF mode became worse at 4 h,and RCR resumed at 24 h in both modes without significant difference compared with the sham operated rats.The echocardiography showed VF mode had a lower left ventricular ejection fraction (LVEF) than asphyxia mode at 4 h (29.68％ vs.42.16％,P =0.03),and there was no difference in LVEF between VF mode and the sham operated rats at 24 h,however no difference in LVEF between the asphyxia and sham operated rats at 72 h.Both of them had a thicker left ventricular anterior wall than the sham operated rats at 72 h (2.41 mm vs.1.72 mm,P=0.013; 2.61 mmvs.1.72 mm,P=0.007),and there was no significant difference between them.Conclusions The ventricular fibrillation mode has a more severe injuries in early period,but it recovers sooner than asphyxia one.Both of two groups get compensatory left ventricular hypertrophy in later period of ROSC.
