Adult-onset Still′s disease (AOSD) is a type of systemic inflammatory disease of unknown etiology, with diverse clinical manifestations, and there are some difficulties in its diagnosis and treatment. In recent years, it has been found that some new markers, such as heme oxygenase 1, calreticulin, inflammatory cytokines and advanced glycation end products, can be used for a comprehensive assessment of the activity and severity of AOSD. Moreover, new biological agents, such as tumor necrosis factor inhibitors, interleukin-1 (IL-1) inhibitors, IL-6 inhibitors and recombinant IL-18 binding proteins, bring new hope for the treatment of AOSD. This review mainly summarizes progress in the diagnosis and treatment of AOSD.

In 2019, a lot of new progress was made in the pathogenesis, diagnosis and evaluation, and treatment of SLE in China and other countries, and this review summarizes main representative advances.

Objective To examine the effects of Shenqi Bufei Tang decoction on the expression of histone deacetylase-2 ( HDAC2) and nuclear factor-κB p65 ( NF-κB p65) in the airway smooth muscle tissues of COPD rats with lung-qi deficiency syndrome. Methods A total of 40 male rats were randomly divided into normal control group,model control group,Shenqi Bufei Tang decoction group,and aminophylline group.The COPD rat model with lung-qi deficiency syndrome was established by intra-tracheal instillation of lipopolysaccharide (LPS) and passive smoking for 28 days.Pathological changes of lung tissues were ob-served under the light microscope and the thickness of the small airway wall and airway smooth muscle ( ASM) layer analyzed by the image analysis.Immunohistochemistry,real-time PCR and Western blotting were used to detect the expressions of NF-κB p65 and HDAC2 in ASM. Results The thickness of the airway wall and ASM,and the expression levels of NF-κB p65 mRNA and protein were significantly increased in the model control group when compared with those in the normal control group ( P<0.05) . They were significantly reduced and the expression levels of HDAC2 mRNA and protein were markedly increased in Shenqi Bufei Tang decoction group and aminophylline group,which were compared with those in the model group (P<0.05).There were no sig-nificant differences in these indices between Shenqi Bufei Tang decoction group and aminophylline group (P>0.05). Conclu-sion Shenqi Bufei Tang decoction can inhibit the proliferation of ASM in COPD rats with lung-qi deficiency syndrome,which may be associated with the increased expression of HDAC2 and decreased expression of NF-κB p65.

Objective:To explore the clinical features of Sweet′s syndrome and analyze its histopathological features and treatment.Methods:The general data, clinical manifestations, laboratory examination, histopathological examination and treatment of 36 patients with Sweet′s syndrome who admitted our hospital from 2013 to 2019 were retrospectively analyzed.Results:The male to female ratio is 1∶1, with the highest incidence in the 50-60 years old range (27.8%). Skin lesions were more common in head and neck (30.6%), limbs (27.8%), upper limbs (19.4%) and whole body (22.2%). Accompanying symptoms were observed in 20 patients (55.6%) and most common are fever (47.2%) and joint pain (19.4%). Malignant tumors were associated with 5 patients (13.9%), chronic inflammation or infection with 17 patients (47.2%), diabetes mellitus with 4 patients (11.1%) and pregnancy with 3 patients (8.3%). It is most easily misdiagnosed as erythema polyforms (11.1%) and allergic dermatitis dermatitis (11.1%). Histopathologic features ware dermal papillary edema, dermal neutrophilic infiltration and nuclear dust. All patients relieved after glucocorticoid therapy.Conclusions:The proportion of male and female in Sweet syndrome is close to the same. Chronic infection and malignant tumor are the most common causes, which are easy to be misdiagnosed in clinic. Comprehensive evaluation of patients′ systemic diseases and accurate histopathological analysis are helpful for early identification and diagnosis of Sweet syndrome.

Objective To understand the psychology and inter-adaptation of patients with in vitro fertilization-embryo transfer (IVF-ET) and their spouses. Methods From August to November 2017, this study selected 13 females with IVF-ET and 13 spouses in Reproduction Center of a Class Ⅲ Grade A hospital in Anhui Province as subjects by purposive sampling. In-depth semi-structured and individualized interview was carried out for those subjects with the phenomenology study of qualitative research. Colaizzi 7-step analysis was used to sort out and analyze interview data. Results Psychological pressure was common in patients with IVF-ET and their spouses and interacted with each other. Totals of four themes were extracted separately, in patients: (1)being worried about IVF-ET and marital status; (2)bearing stress from family, social and themselves; (3)changes of life style and relationship between husband and wife; (4)coping with stress and adjustment mode solely; in spouses: (1)being worried about IVF-ET and physical condition of their wives;(2)bearing stress from family, work and economy;(3)changes of life style and relationship between husband and wife, (4)lack of coping with stress and adjustment mode. Conclusions We should pay attention to psychological pressure and interaction of IVF-ET patients and their spouses, influence of spouse support and coping style on psychology of IVF-ET patients. Take professional measures to improve the pregnancy outcome by providing targeted health guide and psychological intervention for couples.

OBJECTIVEThe effect of triptolide on the DNA methylation level of MMP-9 gene and the mRNA expression of tissue inhibitors of met-alloproteinases (TIMPs) were examined in human fibrosarcoma HT-1080 cells to explore the molecular mechanisms involved in the anticancer activity of triptolide.

METHODHT-1080 cells were cultured in MEM containing 10% newborn calf serum and 1% penicillin-streptomycin. Triptolide was dissolved in dimethyl sulfoxide (DMSO) at a concentration of 1 goL-1 and stored at -20 degrees C. Triptolide was freshly diluted with culture medium perior to use and directly added to cell cultures at the indicated concentration, and incubated for 72 hours at 37 degrees C in a humidified atmosphere with 5% CO2, with changes of reagents every 24 hours. Methylation specific PCR (MSP)was applied to assess the methylation status of MMP-9 gene promoter, and semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was employed to measure the mRNA expression of tissue inhibitors of metalloproteinases (TIMPs) in human fibrosarcoma HT-1080 cells after 72 hours of treatment with 6 nmol x L(-1), 12 nmol x L(-1) or 18 nmol x L(-1) triptolide, respectively.

RESULTSThe methylation index of MMP-9 gene promoter was statistically elevated in HT-1080 cells after 72 hours of treatment with 18 nmol L(-1) triptolide, compared with those in controls (0.61 +/- 0.10 vs 0.39 +/- 0.10, P < 0.05), while no significant difference was noted between 6 nmol x L(-1) or 12 nmol x L(-1) triptolide treated HT-1080 cells and controls (0.40 +/- 0.15 vs 0.39 +/- 0.10, 0.46 +/- 0.20 vs 0.39 +/- 0.10, respectively, both P > 0.05). The mRNA expression of TIMP-1, -2, -3 or -4 was not significantly changed in HT-1080 cells after 72 hours of treatment with the indicated concentrations of triptolide, respectively compared with those in controls (all P > 0.05).

CONCLUSIONThe results demonstrated that triptolide upregulates the methylation level of MMP-9 gene in HT-1080 cells in vitro.

The dynamic changes of cognitive function has been paid more and more attention by foreign scholars.Dynamic assessment based on ecological momentary assessment(EMA)can capture subtle changes in cognitive function and provide more comprehensive information for early identification and timely intervention of people with cognitive impairment, which is an effective supplement to traditional cognitive assessment.This paper reviewed the concept of ecological momentary assessment, its advantages in cognitive assessment, its feasibility and effectiveness, and its application status in the evaluation of cognitive function in the elderly, so as to provide a reference for making ecological assessment of the cognitive function for older adults that is in line with China's national conditions.

A 24-year-old female patient presented with recurrent itchy annular erythema and scales on the trunk and extremities for 9 years. Histopathological study revealed hyperkeratosis with focal parakeratosis, neutrophil aggregation in the stratum corneum, blisters below the stratum corneum, and perivascular infiltration with lymphocytes, a small number of eosinophils and neutrophils in the superficial and middle dermis. Direct immunofluorescence assay showed negative staining for IgG, IgM, IgA and C3. Whole-exome sequencing of the SPINK5 gene showed a missense mutation c.2423C>T (p.T808I) in exon 25, and a splicing site mutation c.2965-1G>A in exon 31. The compound heterozygosity for the two mutations may be the cause of Netherton syndrome in the patient. Based on the clinical manifestations and genetic testing results, the patient was diagnosed with Netherton syndrome.
