Septic shock is one of the leading causes of death in children，especially infants，both domestically and internationally.Research has found that patients with septic shock often have abnormal thyroid function，which affects their prognosis.This article reviewed the changes in thyroid hormone and thyroid-stimulating hormone levels，the reasons for these changes，and the mechanisms by which thyroid function affects the immune system in patients with septic shock,aiming to provide new ideas for clinical treatment.

Background Climate change has resulted in long-term impacts on human health. Implementing efficient adaptation strategies among primary healthcare facilities is well determined by whether staff of different genders recognize the health risks related to climate change and are willing to take active measures. Objective To investigate gender differences on perceptions of health risks and attitude towards adaptation strategies among primary healthcare workers in China, and provide relevant suggestions. Methods By adopting a multi-stage cluster sampling method, we selected 21 urban and 10 rural healthcare facilities in Guangdong Province to collect information with a questionnaire. Then chi-square test, Wilcoxon rank sum test, and logistic regression analysis were used to explore the gender differences in climate change-related health risk cognition, knowledge acquisition channels, attitudes towards adaptation strategies, main obstacles, and resource requirements among the healthcare workers. Results Of 733 participants, 38.47% (282 participants) were male and 61.53% (451 participants) were female. The percentages of male healthcare workers who agreed that climate change is happening and recognized the causes of climate change (70.21%, 60.99%) were higher than the percentages of female counterparts (59.87%, 49.00%) (both Ps＜0.05), but no obvious gender differences existed in recognizing health risks of heatwaves and infectious diseases as well as sensitive population identification (all Ps＞0.05). Most of the participants (92.50%) received climate change and health-related information from mass media like TV, radio, and newspapers. Meanwhile less men chose new media channels than women (OR=0.62, 95%CI∶ 0.41-0.94). Only 30.56% of the participants (33.69% of men and 28.60% of women) reported involvement of relevant training and lectures. Most of them (90.96%) agreed to take active measures to deal with the health threats associated with climate change without gender differences for various measures (all Ps＞0.05). The leading obstacles were hard to integrate health adaptation to climate change into main work of institutions (most female agreed, 72.28%) and the lack of funds (most male agreed, 77.66%). Increasing funding for primary health care was regarded as the most needed resource by male (86.88%) and female (89.14%). After controlling the influence of other social factors, more men agreed with the lack of funds than women (OR=1.57, 95%CI∶ 1.10-2.24). Conclusion There are some gender differences in the perceptions of health risks and adaptation strategies of climate change among primary healthcare workers: Male staff are more likely to agree with climate change and regard the lack of funds as the main obstacle, while women prefer to choose new media channels to obtain information. It’s suggested that the government and relevant institutions focus on the learning and training of climate change and health-related knowledge and expand diversified information access, and promote capacity building to cope with health threats at grass-root level, in the light of recognized gender differences among primary healthcare workers.

OBJECTIVE:To observe therapeutic efficacy and safety of cefoperazone sodium and sulbactam sodium combined with Shenmai injection in the treatment of elderly stroke associated pneumonia(SAP). METHODS:A total of 84 SAP patients in Dazhou Municipal Central Hospital during Mar. 2016-Mar. 2017 were divided into control group(42 cases)and observation group (42 cases)according to random number table. Based on routine treatment,control group was additionally given Cefoperazone sodium and sulbactam sodium for injection 3 g added into 5% Glucose injection 100 mL,intravenously,twice a day;suitable antibiotics were selected according to the results of pathogenic examination and drug sensitivity test. Observation group was additionally given Shenmai injection 100 mL added into 5% Glucose injection 250 mL intravenously,once a day,on the basis of control group. Both groups were treated for consecutive 2 weeks. Clinical efficacies of 2 groups were observed,and the levels of T-lymphocyte subsets(CD4+,CD8+,CD4+/CD8+)and inflammatory markers(TNF-α,hs-CRP,PCT),length of hospital stay before and after treatment. The ADR was recorded. RESULTS:The total response rate(95.24%)and marked response rate (47.62%)of observation group were significantly higher than those of control group(83.33%,23.81%);length of hospital stay in observation group [(15.24±3.53)d] was significantly shorter than control group [(18.43±4.21)d],with statistical significance (P<0.05).After treatment,the levels of CD4+and CD4+/CD8+in 2 groups were significantly higher than before treatment,and the observation group was significantly higher than the control group;the levels of CD8 +,TNF-α,hs-CRP and PCT in 2 groups were significantly lower than before treatment;the observation group was significantly lower than the control group,with statistical significance(P<0.05);there was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,cefoperazone sodium and sulbactam sodium combined with Shenmai injection treat SAP significantly,can effectively improve immune function, reduce inflammation level and shorten the length of hospital stay without increasing the occurrence of ADR.

Objective:To investigate the expression of CD56 antigen in leukemia cells of the patients with acute myeloid leukemia (AML)and its relationship with the prognosis of AML, and to clarify the role of CD5 6 antigen expression in predicting the prognosis of the AML patients.Methods:171 AML (non-M3)patients aged from 14 to 60 years old,who received a IA Regimen as the first time inducing chemotherapy were chosen.Flow cytometric analysis was used to evaluate the CD56 expression in leukemia cells.COX proportional regression analysis was used to select the prognostic factors,and bivariable analysis was used to study the relationship between the positive rate of CD56 and overall survival (OS).The CD56+ group (n=52),including CD56≥50% expression group (n=39) and CD56<50% expression group (n=13),and CD56- group (n=119)were identified by the expression of CD56 antigen.The complete remission rate (CRR), the relapse rate, the median OS, the median disease-free survival (DFS)and the survival rate of patients were compared.Results:The medium OS of the patients in CD56+ group (14.2 months)was shorter than that in CD56- group (39.4 months)(P<0.05).Moreover,the medium OS in CD56≥50% group was shorter than that in CD56<50% group (11.7 months vs 20.3 months,P<0.05).The 1-year and 2-year survival rates of the patients in CD56+ group (61.5%,46.2%)were lower than those in CD56-group (75.6%,63.9%)(P<0.05).The 1-year survival rate had no significant difference between CD56≥50%group and CD56<50% group (53.8%vs 84.6%,P>0.05),while the 2-year survival rate in CD56≥50% group was lower than that in CD56<50% group (41.0%vs 61.5%,P<0.05).There were no significant differences of the CRR between CD56+ group (76.9%)and CD56- group (68.9%)as well as CD56≥50% group (58.9%)and CD56<50% group (63.5%)(P>0.05).The relapse rate and first year relapse rate of patients in CD56+ group (64.3% and 37.5%)were significantly higher than those in CD56- group (34.3% and 17.9% )(P<0.05). However,there were no significant differences of the relapse rate and first year relapse rate between CD56≥50%group (75.0% and 42.9%)and CD56<50% group (37.5% and 16.7%)(P>0.05).The DFS in CD56+ group was shorter than that in CD56- group (P<0.05).The same DFS result was also found between CD56≥50%group and CD56<50% group (P<0.05).Conclusion:The expression of CD56 antigen in leukemia cells predicts a bad prognosis in the AML patients,and the higher expression of CD56 indicates the worse prognosis.

Objective To investigate the clinical features and mechanism and feasibility of plasma exchange (PE) in treating systemic lupus erythematosus (SLE) complicated with acute pancreatitis (AP). Methods A retrospective analysis of SLE associated with AP was done based on the HIS in Tongji Hospital. Totally 24 SLEAP patients were admitted to Tongji hospital from March 2006 to May 2014. Patientsˊ serum amylase, lipase and interleukin (IL)-6 concentration were measured before and after plasma exchange. According to different therapy strategy, patients were divided into two groups. Fifteen patients treated with plasma exchange combination with glucocorticosteroid (GC) were classified as Group A, the other 9 patients who were treated with GC only were classified as group B. At baseline and after treatment, the serum lipid concentration, average daily glucocorticosteroid dosage between group A and B were compared with ANOVA and serum IL-6 concentration between roup A and B were compared with Wilcoxon rank test. Results SLEDAI score in group A patients at baseline (16 ±5) was no statistically different from that in group B (18 ±4) (t=1.31, P=0.320). Average daily GC dosage in group A 31.0 (20.50, 30.08)mg/d was significantly less than that in group B 47.85 (45.58, 59.23) mg/d (Z=35.50, P= 0.002). Serum IL-6 levels in group A and B at baseline was not significantly different 13.14 (11.12,16.57) mg/L vs 14.63 (11.37, 16.37) mg/L (Z=12.20, P=0.300), after 2 weeks treatment, IL-6 level, which was 9.16 (7.93, 10.75) mg/L, decreased significantly in group A while it didnˊt show tendency of decrease in group B, which was 13.62(9.29, 17.63) mg/L (Z=28.50, P=0.039). Serum lipid concentration after 2 weeks therapy in Group A [TC=(5.02 ±0.53) mmol/L, TG=(1.46 ±0.44) mmol/L] decreased significantly compared to baseline [TC=(6.11±0.50) mmol/L, TG=(2.14±0.65) mmol/L] (F=4.46, P=0.010; F=6.09, P=0.002), while similar tendency wasnˊt observed in group B (F=1.57, P>0.05). Conclusion PE combined with GC could lower serum IL-6 levels, reduce the amount of GC and lower serum lipid to improve prognosis. Therefore it might be a safe and effective way and is worthy of continuing to explore its feasibility.

Objective To evaluate the three-dimensional reconstruction and significance of arterial cast on chronic venous insufficiency of low extremity. Methods A set of specimen on chronic venous insufficiency of left lower extremity amputation residues was infused with epoxy resin-lead oxide through the femoral artery,and then casted. The CT data of the cast specimen was used to reconstruct 3D modal of ar-tery on chronic venous insufficiency of left lower extremity,using the volume rendering(VR) and maximum intensity projection(MIP). Re-sults The cast specimen and 3D reconstruction of chronic venous insufficiency of left lower extremity amputation residues could clearly dis-play distribution and run of lower extremity arteries,blood supply of lesion and local region embolism of small artery ( arteriole) . Conclusion The 3D modal of artery on chronic venous insufficiency of left lower extremity should provide morphological basis of exact etiology and perfect pathogenesis,also has a certain guiding significance of clinical diagnosis and treatment.

ObjectiveTo examine the clinical features of fractures and related risk factors in patients with rheumatoid arthritis(RA) in China.MethodsSix hundred and eighty-one RA patients were randomly selected from department of rheumatology of 18 hospitals of China.Data were obtained from the questionnaire,including age,sex,disease duration,the involvement of joints,treatment regimen,features of fractures etc.The possible risk factors of fracture in patients with RA were analyzed with a multi-variate Logistic regression analysis.Results① In 681 RA patients of the survey,48 patients had 54 fractures,and the incidence of fractures was about 8％.② Fractures occurred at various sites.Foot/ankle,femur,spine and wrist were the mostfrequent sites.③ The Logistic regression analysis showed that several factors increased the risk of fracture in RA patients,including long disease duration (OR:1.245,95％CI:0.987-1.570,P=0.065),male gender(OR:0.433,95％CI:0.199-0.942,P=0.035),more deformed joints(OR:1.042,95％CI:1.006-1.079,P=0.023),family history of RA (OR:2.201,95％CI:0.984-4.923,P=0.055),and high scores of SF-36(OR:1.017,95％CI:1.002-1.033,P=0.028).④ According to the degree of correlation from strong to weak,the risk factors of fracture were disease duration,SF-36,sex,number of deformed joints and family history of rheumatoid arthritis.ConclusionThe incidence of fracture is high in patients with rheumatoid arthritis.Several factors could increase the risk of fractures in RA patients,including long disease duration,male gender,more deformed joints,and family history of RA.In order to prevent the occurrence of fractures,cautions should be taken to prevent the development of fractures and treat the disease aggressively to suppress the disease activity of RA.

ObjectiveTo evaluate the clinical and radiological efficacy of TNFR Ⅱ -Fc combined with methotrexate( MTX ) in treatment of patients with moderate and severe rheumatoid arthritis.MethodsThree hundred and ninty-six RA patients were randomized into the combined treatment group,the TNFR Ⅱ -Fc only group and MTX only group.All patients were treated for 24 weeks.ACR-N,ACR20,ACR50,ACR70,DAS28-ESR and Sharp score of both hands were measured for efficacy,and the side-effects were analyzed by one-way ANOVA.Results After 24-week therapy,the ACR-N of the combined treatment group [( 12.79±9.24)％-year] was significantly improved than that of the TNFR Ⅱ-Fc only group [(9.56±11.16)％-year,P＜0.05] and that of the MTX only group[(5.08±11.10)％-year,P＜0.05],and the TNFR Ⅱ-Fc group was significantly improved than that of the MTX group(P＜0.05).The ACR20 response rate of the combined group(80.4％) was significantly higher than that of the TNFR Ⅱ -Fc group(71.1％,P＜0.05) and the MTX group(56.7％,P＜0.01 ).The ACRS0 response rate of the combined group(53.6％) was significantly higher than that of the MTX group(30.8％,P＜0.01 ).The ACR70 response rate of the combined group was 27.7％,which was significantly different from that of the TNFR Ⅱ -Fc group (15.8％) and MTX group (7.7％,P＜0.05or P＜0.01 ).DAS28-ESR in the combination group was significantly reduced than those of the TNFR Ⅱ -Fc group and MTX group,and the DAS28-ESR of the TNFR Ⅱ -Fc group was significantly reduced than MTX group.The average total Sharp score of both hands,which demonstrated the radiographic changes,was significantly reduced in the combination group than the MTX group(P=0.03).The total adverse events in the combined group(40.9％) was significantly high than that of the MTX group(28.8％,P＜0.05).Conclusion TNFR Ⅱ -Fc combined with MTX can effectively control the activity of RA and radiological progress.

Objective To describe the distribution of medication costs of rheumatoid arthritis patients, and to analyze the factors that may affect the costs. Methods Data were obtained from a 12-month retrospective investigation of patients with rheumatoid arthritis (RA) across China. Department of Rheuma-tology of 18 hospitals were randomly selected. The data about their social conditions, clinical conditions, medications associated with RA such as disease-modifying antirheumatic drugs (DMARDs), non -steroidal anti -inflammtory drugs (NSAIDs), steroids, biologic agents were collected, and the costs of drugs were calculated. A non-parameter test and multivariate logistic regression analysis were performed. Results Six hundred and forty six patients were enrolled into the study, 435 completed data were chosen for analysis. The results demonstrated that the average costs per patient for medications in the past year was 8018 . The total medication costs were further subdivided into the following parts: DMARDs, (represented 20% of the total costs), biologic drugs (49%), NSAIDs (4%), herbal drugs (22%), steroids (1%). Data analysis showed that patients with higher education and higher incomes, with medical insurance,better health function status and outpatients paid more on DMARDs. Extra-articular manifestations increased the odds of the high-cost group (OR: 2.180, 95%CI: 1.335～3.558, P=0.002), while poor health function status increased the probability of paying high costs (OR: 1.373, 95%CI: 1.012～1.863, P=0.041). Conclusion High medication costs in RA do exist in RA patients. The costs of medication is associated with health function status and the presence of extra-articular manifestations.

Objective To establish the animal model of damp-heat syndrome(DHS) and explore the expression of aquaporin(AQP) 3,4 gene in gastric mucosa.Methods Thirty SD rats were randomized into 3 groups and observed for 20 days.Group A(normal group,NG) was fed with routine method.Group B(Pi deficiency syndrome group,PDS) was fed alternatively with routine method and aqua of cassia angustifolia Vahl.Group C(DHS) was fed with fat,honey liquid and treated with damp-heat environment.The expression of AQP 3,4 gene in the 3 groups were determined by fluorescence quantitative polymerase chain reaction(FQ-PCR).Results The symptoms and signs in Group C were simiar to the clinical DHS.Expression of AQP3 gene in DHS was statistically significant higher than that in PDS and NG(P
