Macrophages play an important role in the pathogenesis of rheumatoid arthritis (RA). Previously, studies have shown that changes in the metabolism of glucose, choline, amino acids and lipids in macrophages of patients with RA can lead to the accumulation of metabolic intermediates which can act as inflammatory signaling molecules to aggravate the inflammation and cause complications. Therefore, a full understanding of the metabolic process of macrophages in RA patients will lay the foundation for macrophage-targeted therapy of RA. In this review, not only the role of macrophage abnormal metabolism in the pathogenesis of RA but also the research progress on macrophage-targeted drugs in RA treatment will be discussed.

Objective To observe the level of serum IFN-2? in patients with severe acute respiratory syndrome(SARS). Methods The level of serum IFN-2? in 66 patients with SARS were measured by RIA, and healthy subjects served as control. Results The results showed that level of serum IFN-2? in patients with SARS in active period were significantly higher than that in control, and level of serum IFN-2? in severe type of patients with SARS either rose or fell. Conclusions The change of serum IFN-2? level indicated that cellular immunity participated in immunoreaction to SARS virus. The change of IFN-2? level in severe type of patients with SARS reflected the difference of immunoreaction in the patients.

T polymorphism of TGF-?1 gene related with the degree of L_(4?5) and L_5S_1 disc degeneration.

Objective To observe the effect of human β-defensins-2(HBD-2) for chorioamnionitis(HCA) pregnant women before term premature rupture of fetal membrane(PROM) process,and explore toll-like receptor 4 / nuclear factor-κ B (TLR4 / NF-κB) predominate role in the process of signal transduction pathway in the mechanism.Methods Fifty five women with PROM were enrolled in the study.According to the Results of pathological diagnosis of membranes,pregnant women with PROM divided into histological chorioamnionitis,HCA and non-HCA.The same sample without PROM pregnancies matching the same gestational ages were recruited as control group.We examined the messenger RNA(mRNA) of TLR4,NF-κB p65 and HBD-2 in placenta and fetal membrane real-time reverse transcription polymerase chain reactions by dsDNA-binding dyes of SYBR Green.Results (1)In the placenta,the level of TLR-4(17.15±4.52),NF-κB p65(47.11±14.23),HBD-2mRNA(27.35±2.67) in PROM group were significantly higher than the level of TLR-4(7.21±3.25),NF-κB p65(30.51±13.05),HBD-2mRNA(13.55±0.8) in control group(t=-1.966,-1.474,-1.754,P<0.05).In the fetal membrane,the level of TLR-4(18.54±3.35),NF-κB p65(49.29±16.18),HBD-2mRNA(25.19±3.39) in PROM group were significantly higher than the level of TLR-4(6.88±2.75),NF-κB p65(32.41±11.45),HBD-2mRNA(13.80±2.21) in control group(t=-2.378,-1.487,-1.847,P<0.05).In the placenta,the level of TLR-4(19.35±4.12),NF-κB p65(49.3±13.36),HBD-2mRNA(31.54±2.43) in HCA group were significantly higher than the level of TLR-4(6.71±2.25),NF-κB p65(32±12.25),HBD-2mRNA(7.41±0.45) in non-HCA group(t=-3.456,-1.547,-5.324,P<0.05).The level of TLR-4(7.78±2.65),NF-κB p65(8.48±1.01),HBD-2mRNA(30.45±11.42) in HCA group were significantly higher than the level of TLR-4(7.78±2.65),NF-κB p65(30.45±11.42),HBD-2mRNA(8.48±1.01) in non-HCA group(t=-3.654,-1.654,-6.352,P<0.0).(3)HCA group women:there were positive correlations between TLR4mRNA and NF-κB p65 mRNA,TLR4mRNAand HBD2 mRNA,TLR4mRNA and HBD2 mRNA(r=0.334,0.427,0.432,0.562,0.471,0.392,P<0.01)(4;)Non-HCA group women:there were positive correlations between HBD-2 and NF-κB p56(r=0.492,0.298,P<0.01),there had no correlation betweenTLR4mRNA and NF-κB p65mRNA,TLR4mRNAand HBD2 mRNA(P>0.05).Conclusion Linear positive correlation of TLR4,NF-κB and HBD2 indicated that TLR4/NF-κB/HBD2 signal transduction pathway may be involved in the development of preterm premature rupture of membrane associated with histologic chorioamnionitis.

Objective To explore the feasibility of nasolabial sulcus flap transfer with autologous free skin graft to repair the alar defects after malignant tumor resection.Methods From January 2012 to January 2015,9 patients with malignant tumor were treated in the hospital.After complete tumor removal,the defect area being reconstructed was 1.5 cm × 1.3 cm to 2.5 cm × 2.5 cm.The defects of 9 patients were all restored with nasolabial sulcus flap combined with autologous free skin graft.Results The 9 patients were followed up for 6-18 months postoperatively.The nasolabial sulcus flap and autologous free skin graft were survived completely in all cases.Symmetrical alae were noted with slight edema within nasal cavity but without difficult ventilation.Scar was repaired in phase-two surgery.Conclusions Nasolabial sulcus flap combined with autologous free skin graft is an optional way in alar defects restoration.Further with secondary morphologic plasty,satisfactory surgical outcome can be achieved.

Objective To explore whether 5 to -7-day of folic acid supplementation prior to pemetrexed therapy is needed. Methods We retrospectively evaluate the outcomes of non-small cell lung cancer patients received less than the advised folic acid premedication. Seventy patients with Ⅲ-Ⅳ NSCLC were randomly divided into two groups: patients who initiated vitamin supplementation on 7 days before the first dose of pemetrexed (group A) and patients who initiated vitamin supplementation on the day of the first dose of pemetrexed (group B). Results In group A and group B, CR 0 and 0, PR 10 and 8, the response rates of 28.6% and 22.9% were observed, respectively. There was no statistically significant differences between these two groups. No significant differences were observed in the incidence of hematologic and non-hematologic toxicities. Conclusions The initiation of pemetrexed-based chemotherapy does not need to accommodate a vitamin supplementation schedule.

Objective To investigate the changes of pathogens distribution and antimicrobial resistance in children with urinary tract infection (UTI) in 10 years. Methods The results of urine culture and drug sensitivity in children with UTI from January 2001 to December 2003, and from January 2011 to December 2013 were retrospectively analyzed.Results In recent 10 years, there was no obvious change in the ratio of gram-negative bacteria to gram-positive bacteria. Escherichia coli was still the main bacteria causing UTI in children. The detection rate of enterococcus was signiifcantly increased from 18.3%in 2011-2013 to 7.5%in 2001-2003 (P<0.05) and it had become the second pathogenic bacteria. The isolation rate of ESBLs producing strains was signiifcantly higher in 2011-2013 than in 2001-2003 (P<0.05). The rate of Escherichia coli sensitive to imipenem re-mained at 100%and it is also sensitive to enzyme inhibitors antibiotics and nitrofuranto. Sensitivities to antibiotics were changed in different species of enterococcus. Conclusions The distribution of pathogens and antimicrobial resistance in children with UTI are constantly changing. The clinician should pay close attention to changes of epidemiology in the region and hospital and rational use of antimicrobial drugs.

Objective To restore the incisal angle defect of anterior upper teeth with partial cov-erage porcelain veneer, and evaluate the clinical performance of the restoration. Methods A total of 12 patients were included, and 14 anterior upper teeth with small incisal angle defect were involved in this study, after tooth reduction of 2 mm wider than the defect of every teeth, 14 partial coverage IPS-Empress Ⅱ veneers were made and binded with Variolink Ⅱ adhesive system. During the observation period of 36-48 months after insertion, prosthodontic results were evaluated, using the CDA quality e-valuation system, and marginal integrity, anatomic form, surface and color of the veneers, and sec-ondary caries were examined. Results During the period of 36-48 observation, all of the 14 restora-tions were rated satisfactory. Conclusions With strict control of indications, the partial coverage porcelain veneer could function satisfactorily as an alternative restoration for small incisal defect of an-terior upper teeth.
