We presented a new method for vessel segmentation and vascular structure recognition for coronary angiographic images. During vessel segmentation, a new vessel function was proposed to attain vessel feature map. Then the region growing algorithm was implemented with an automatic selection of seed point, extraction of main vessel branch, and vessel detail repairing. In the algorithm of vascular structure recognition, a fuzzy operator was used, which can detect the structures of vascular segments, bifurcations, crosses, and tips. The experimental results indicated that there was about 5 percent larger vessel region which was extracted by the proposed segmentation method than that by the simple region growing algorithm, and several thinner vessels were resumed from the lower gray region. The results also indicated that the fuzzy operator could correctly infer the simulative and real vessel structure with 100% and 90.59% correctness rate on the average, respectively.

OBJECTIVETo explore the therapeutic effect of auricular therapy combined with optimized Yinxieling Formula on psoriasis vulgaris.
METHODSA randomized controlled single-blind clinical trial on 84 outpatients with psoriasis vulgaris was conducted. The patients were randomized to a treatment group (43 cases treated by auricular therapy combined with optimized Yinxieling Formula) and a control group (41 cases treated by optimized Yinxieling Formula alone) according to a random number generated by SPSS 17.0 software. The treatment duration for both groups was 8 weeks. The therapeutic effect was comprehensively measured by the primary outcome measure [Psoriasis Area and Severity Index (PASI) reduction rate] and the secondary outcome measure [PASI, Visual Analogue Scale (VAS), Dermatology Life Quality Index (DLQI), Self-rating Depression Scale (SDS), and Self-rating Anxiety Scale (SAS)]. The outcomes of both groups were obtained and compared before and after the intervention.
RESULTSThe PASI reduction rate in the treatment group was 74.4% (32/43), which was higher than that in the control group (36.6%, 15/41, P<0.01). The PASI scores decreased in both groups after treatment and was lower in the treatment group compared with the control group P<0.01). With stratified analysis, there were significant differences between the PASI scores in the following subgroups: age 18-30, baseline PASI>10 and stable stage (P<0.05). DLQI decreased in both groups on some categories after treatment, but there were no significant differences between the two groups in SDS, SAS and VAS (P >0.05). No obvious adverse reactions were found in either group.
CONCLUSIONThe therapeutic effect of auricular therapy combined with Optimized Yinxieling Formula was superior to Optimized Yinxieling Formula alone with no obvious adverse reaction.

Since the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China, the public-facility-turned temporary hospital (PFTH) has played an important role in preventing the spread of the epidemic. Wuchang PFTH is the first one to put into clinical practice and the last one suspended in Wuhan. The National Emergency Medical Rescue Team of the Second Xiangya Hospital of Central South University, together with other 13 medical teams (841 medical staff in total), have fulfilled the task for the treatment of non-severe COVID-19 patients, without any medical staff infected. The first author of the article was the only pediatrician working in the Wuchang PFTH. The author describes and summarizes the features/functions, management/operations, and advantages/challenges of the PFTH, in order to provide reference for medical institutions and relevant departments to deal with public health emergencies.

OBJECTIVETo establish determination methods of eotaxin mRNA and TNF-alpha mRNA expression in the lung tissue of mice.
METHODSEotaxin mRNA and TNF-alpha mRNA expressions were determined by semi-quantitative RT-PCR. The functional implications of eotaxin mRNA and TNF-alpha mRNA expression were examined by detecting the numbers of total leucocytes and eosinophils in bronchoalveolar lavage fluid(BALF).
RESULTEotaxin mRNA and TNF-alpha mRNA expression in lung tissue total numbers of leucocyte and numbers of eosinophil in BALF increased in sensitized mice compared with those in normal mice. Dexamethasone significantly but did not inhibit eotaxin mRNA and TNF-alpha mRNA expressions, and eosinophil infiltration in the lungs of the sensitized mice. A compound preparation of traditional Chinese medicine inhibited eotaxin mRNA and eosinophil infiltration, influenced TNF-alpha mRNA expression.
CONCLUSIONIncreased eotaxin mRNA expression in lung tissue is associated with eosinophil infiltration in BALF, which indicates that the methods of semi-quantitative RT-PCR may be useful to the study of the mechanism of antiasthmatic medicine.

OBJECTIVETo determine the levels of CC chemokine ligand 5 (CCL5) in serum and synovial fluid (SF) from patients with rheumatoid arthritis (RA) and their relations with disease activity and medication.
METHODSCCL5 in serum and SF was quantified by enzyme-linked immunosorbent assay (ELISA) in 28 RA patients and 21 osteoarthritis (OA) patients. In RA patients, the correlations of CCL5 levels in serum and SF with disease activity were analyzed. Meanwhile, the serum CCL5 levels among RA patients treated with disease-modifying antirheumatic drugs (DMARDs), Tripterygium Glucosides, and other Chinese herbs without disease-modifying effects were also compared.
RESULTSCCL5 levels in both serum and SF of RA patients were significantly higher than those of OA patients (P < 0.05). Moreover, the level of CCL5 was higher in SF than that in serum of RA patients (P < 0.01). Serum CCL5 level was correlated significantly with the number of swollen joints (r = 0.3329, P < 0.05), erythrocyte sedimentation rate (r = 0.4001, P < 0.05), and C reactive protein (r = 0.3735, P < 0.01). In addition, the level of CCL5 had a trend of lower in patients treated with DMARDs or Tripterygium Glucosides than those treated with other Chinese herbs, although the difference was not significant among those patients due to the small number of patients in each group.
CONCLUSIONSIn RA patients, the expression of CCL5 increases and correlates with some clinical and laboratory parameters of RA, which indicate that CCL5 plays an important role in RA and may serve as a useful marker of disease activity. DMARDs and Tripterygium Glucosides might exert their clinical effects through reducing CCL5 production in RA.

Objective To investigate the presentationand significance of circulating autoantibodies to erythropoietin receptor (EPOR) in sera from patients with systemic lupus erythematosus (SLE). Methods One hundred and twenty-four consecutive patients with SLE, seven with autoimmune hemolytic anemia (AIHA), 19 patients with iron deficiency anemia (IDA) and 45 normal individuals were involved in this study. In all patients with SLE, the disease activity was evaluated using the European consensus Lupus Activity Measurement scale. Antibodies to EPOR were detected by enzyme-linked immunosorbent assay (ELISA). All data were tested with Chi-squared or Student's t tests by SPSS software. Results A higher frequency of antibodies to EPOR were detected in SLE patients than healthy controls (20.2% vs 2.2%, P=0.004), however, they could not be detected in AIHA and IDA patients. Moreover, anti-EPOR antibodies were detected in 17 (33.3%) of 51 SLE patients with anemia, compared with that in 8 (11.0%, P=0.002) of 73 patients without anemia. Furthermore, patients with antibodies to EPOR had more severe anemia and often presented as microcytic anemia (P =0.005) than those without anti-EPOR antibodies. Finally, anti-EPOR antibodies seemed to be more likely to occur in patients with skin rash (P=0.014), low levels of C3 component of complement (P=0.01), positive anti-dsDNA antibodies (P=0.000) and higher disease activity scores (P= 0.024). Conclusion The higher incidence of antibodies to EPOR in SLE patients with anemia suggest that anti-EPOR antibodies might play a vital role in the development of anemia in SLE patients. Thus, detecting anti-EPOR antibodies in SLE patients with anemia may be helpful.

OBJECTIVETo examine the expression of FLICE-inhibitory protein (FLIP) in juvenile idiopathic arthritis (JIA) and analyze its correlation with synovial inflammation.
METHODSThe expression of FLIP was assessed in 11 JIA and 3 normal synovial tissue samples by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. The cell types expressing FLIP were further characterized, and the correlation of FLIP expression with the degree of synovial inflammation, as well as the activity of caspase 8 was then analyzed.
RESULTSRT-PCR revealed the expression of FLIP mRNA in all 11 JIA samples, but not in 3 normal synovial tissues. In JIA, FLIP expression could be found in both the lining and sublining layers, mainly in the macrophage-like cells. Moreover, the expression of FLIP in JIA synovial tissues was positively correlated with the degree of synovial inflammation (r = 0.563, P < 0.05).
CONCLUSIONThe expression of antiapoptotic FLIP in JIA synovial tissue and its correlation to accumulation of inflammatory cells in synovial tissue suggests that FLIP potentially extends the lifespan of synovial cells and thus contributes to the progression of joint destruction.
