ABSTRACT
Mucormycosis is an opportunistic fungal infection driven by subphylum Mucormycotina. Cutaneous mucormycosis is the third most common presentation of mucormycosis, and its characterized presentation is an indurated plaque that rapidly evolves to necrosis. Trichophyton rubrum is one of the most common dermatophytes that mainly cause superficial infections and seldom induce deep infections. The present report presents a case of cutaneous fungal infection, in which two kinds of fungus were isolated, and the skin lesion mimicked pyoderma gangrenosum. Trichophyton rubrum was isolated from the crust and hyphae of subphylum Mucormycotina were found in dermal tissue. The irregular systemic and topical use of steroid therapy is the possible cause of the mixed fungal infection in this patient, suggesting the importance of regular steroid therapy.

BACKGROUND: The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which is critically involved in the pathogenesis of a variety of skin diseases. The aim of this study was to detect AhR and its downstream regulators including cytochrome P450 (CYP1A1), AhR nuclear translocation (ARNT), and aryl hydrocarbon receptor repressor (AhRR) in serum, peripheral blood mononuclear cells (PBMCs), and skin lesions in patients with atopic dermatitis (AD). METHODS: Twenty-nine AD patients defined according to the criteria of Hanifin and Rajka and Chinese criteria of AD were included. Subjects without allergic and chronic diseases were recruited as controls. Patients and controls were selected from the dermatology outpatient clinic of Peking University People's Hospital from August 1 to December 31 in 2018. Enzyme-linked immunosorbent assay was performed to detect serum AhR level. The mRNA of AhR, AhRR, ARNT, and CYP1A1 in PBMCs were measured by real-time quantitative polymerase chain reaction. AhR expression in skin lesions was measured by immunohistochemistry. RESULTS: AhR was significantly higher expressed in serum (41.26â±â4.52 vs. 33.73â±â2.49 pmol/L, tâ=â6.507, Pâ<â0.001) and skin lesions (0.191â±â0.041 vs. 0.087â±â0.017, tâ=â10.036, Pâ<â0.001) of AD patients compared with those of controls. The mRNA levels of AhR (1.572â±â0.392 vs. 1.000â±â0.173, tâ=â6.819, Pâ<â0.001), AhRR (2.402â±â1.716 vs. 1.000â±â0.788, tâ=â3.722, Pâ<â0.001), CYP1A1 (2.258â±â1.598 vs. 1.000â±â0.796, tâ=â3.400, Pâ=â0.002) in PBMCs of AD patients were higher compared with those of controls. The difference in mRNA levels of ARNT was not statistically significant between the patients and controls (1.383â±â0.842 vs. 1.000â±â0.586, tâ=â1.653, Pâ=â0.105). AhR mRNA levels in PBMCs positively correlated with eczema area and severity index score and serum interleukin-6 levels. CONCLUSION: AhR and its downstream regulators were highly expressed in serum, PBMCs, and skin of AD patients, which might contribute to the pathogenesis of AD.

ABSTRACT
Objective To explore the clinical factors that can be used to predict the early weight loss after laparoscopic sleeve gastrectomy(LSG).Methods The clinical data of 64 obese patients undergoing LSG in Peking Union Medical College Hospital from August 2015 to January 2018 were retrospectively analyzed.We analyzed the relationship between different clinical factors and early weight loss,determined the independent predictors based on models,and estimated their test power by using the receiver operating characteristic(ROC)curves.Results Correlation analysis indicated that preoperative body mass index(=0.000,=0.000,=0.000),waist circumference(WC)(=0.000,=0.000,=0.000),whole body fat volume(=0.000,=0.006,=0.003),homeostatic model assessment for insulin resistance(HOMA-IR)(=0.000,=0.000,=0.002),and hypersensitive C-reactive protein(hsCRP)(=0.004,=0.002,=0.025)were negatively correlated with excess weight loss percentage(EWL %) after 3,6 and 12 months.Also,hsCRP after 6 months showed negative correlation with EWL % after 1 year(=0.029).Binary Logistic regression analysis showed that WC was an independent predictor of early weight loss(=0.018).ROC analysis showed that when the optimal cutoff value is 142.5 cm for WC, index was highest,with a sensitivity of 80% and a specificity of 87%.Patients were further divided into low WC group and high WC group based on this optimal cutoff value.The low WC group had significantly higher EWL% than the high WC group 3 months(=6.677,=0.000),6 months(=6.157,=0.000),and 1 year(=4.006,=0.000)after surgery.The low WC group also had significantly lower hsCRP than high WC group 6 months after surgery(=-3.510,=0.000).HOMA-IR showed no significant difference between these two groups(=-0.821,=0.412).Conclusions WC is an independent predictor of weight loss early after LSG.The patients with low WC have better weight loss effectiveness.

ABSTRACT
OBJECTIVE@#To investigate the etiology and clinical features of epilepsia partialis continua (EPC) in children.@*METHODS@#A retrospective analysis was performed for the clinical features, diagnosis and treatment of six children with EPC, and the clinical and laboratory features and prognosis were compared between the children with different etiologies.@*RESULTS@#There were five girls and one boy, with an onset age ranging from one year and seven months to nine years. Two were diagnosed with Rasmussen encephalitis, one was diagnosed with focal cortical dysplasia, one was diagnosed with Alpers syndrome caused by POLG gene mutation, one was diagnosed with Angelman syndrome, and one was diagnosed with tuberculous meningitis. The latter two children had the predisposing factors for acute encephalopathy induced by status epilepticus and craniocerebral operation during the onset of EPC, while the other four children had natural progression of EPC. All the children had focal seizures except EPC, and symptoms included automatism, bilateral asymmetric tonic seizure, deflection, complex motor, and autonomic symptoms, with disturbance of consciousness in some children. EPC often lasted for several days or even several months. All children had abnormalities on head MRI, including local abnormal signal, cortex swelling, diffusive brain atrophy or brain atrophy at one side, local cortex thickening, and cortical necrosis. Head PET/CT scan was performed for three children and found local hypermetabolism or co-existence of hypermetabolism and hypometabolism. All the children had abnormalities on electroencephalography (EEG), with cerebral, hemispheric, or diffusive distribution of abnormal electrical activities, and during the onset of EPC, some EEG changes were recognizable and some were difficult to identify. All the children with EPC were not sensitive to antiepileptic drugs. EPC was relatively self-limiting in the child with Angelman syndrome. The child with focal cortical dysplasia underwent resection of epileptic foci and had good postoperative control, without neurological dysfunction. The child with Rasmussen encephalitis underwent functional hemispherectomy and had no attack after surgery, with neurological dysfunction. The child with Alpers syndrome had the worst prognosis.@*CONCLUSIONS@#EPC is a special type of epileptic seizures. Immune inflammation and metabolic etiologies are the main causes of EPC in children, and the selection of treatment regimens, treatment outcome, and prognosis depend on etiology.

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect. Medical records were reviewed for these data. RESULTS: Clinical evaluation and debridement findings of the abdomen revealed 4 patients with suspicious visceral damage. Laparotomy was performed in 4 cases, and revealed obvious lesion in 3 cases, including segmental necrosis of small intestine, partial necrosis of diaphragm, left liver and gastric wall, and greater omentum. Five patients underwent abdominal wall reconstruction using island retrograde latissimus dorsi myocutaneous flap or free/island composite anterolateral thigh myocutaneous flap. All flaps survived, abdominal bulging occurred in 3 cases after follow-up of 12 to 36 months. CONCLUSIONS: The clinical manifestations and wound features of abdomen collectively suggest a possible requirement of laparotomy for severe abdominal electrical burns. Retrograde latissimus dorsi myocutaneous flap or composite anterolateral thigh myocutaneous flap is an effective option for reconstruction of abdominal wall loss, the long-term complication of abdominal bulging, however, remains a significant clinical challenge.

BACKGROUND: Graft-versus-host disease (GVHD) is a common complication of hematopoietic stem cell transplantation. Skin barrier disruption could induce thymic stromal lymphopoietin (TSLP) expression, and the expression of TSLP was increased in lesions of atopic dermatitis (AD)-like GVHD and lichen planus (LP)-like GVHD. This study attempted to investigate the skin barrier function of AD-like GVHD and LP-like GVHD and possible mechanisms. METHODS: Eighteen AD-like GVHD patients, 12 LP-like GVHD patients, and 14 healthy volunteers were enrolled in this study. Skin biopsy was done in five AD-like GVHD patients, eight LP-like GVHD patients, and eight healthy volunteers. The intensity of pruritus was assessed by visual analog scale itch score and detailed pruritus score. Transepidermal water loss (TEWL) was measured using Tewameter® TM 300. Immunohistochemistry was used to observe the expression of loricrin, involucrin, LL37, and human ß-defensins 2 (hBD2) in skin lesions. Western blot analysis was used for analyzing the protein levels of loricrin and involucrin in skin lesions. Real-time polymerase chain reaction was performed to assess the mRNA levels of LL37 and hBD2 in skin lesions. RESULTS: Pruritus score was higher in patients with AD-like GVHD (11.33 ± 5.35) than that of patients with LP-like GVHD (2.58 ± 3.09, P< 0.001). Compared with healthy controls (HCs, 4.52 ± 1.24 g·m-2·h-1), TEWL was increased in AD-like GVHD (26.72 ± 9.02 g·m-2·h-1, P < 0.001) and LP-like GVHD patients (18.78 ± 4.57 g·m-2·h-1, P< 0.001), and expressions of loricrin and involucrin were also increased in skin lesions of AD-like GVHD and LP-like GVHD patients (all P< 0.05). LL37 mRNA expression was decreased in lesions of AD-like GVHD and LP-like GVHD patients (P = 0.005 and P = 0.008, vs. HCs, respectively). hBD2 mRNA expression was increased in skin lesions of AD-like GVHD and LP-like GVHD patients (P = 0.002 and P< 0.001, vs. HCs, respectively). CONCLUSIONS: Skin barrier dysfunction is present in AD-like GVHD and LP-like GVHD. The immunoreactions, but not the congenital defect, are considered to be the primary cause of skin barrier impairment in AD-like GVHD and LP-like GVHD.

Aim To primarily discuss the mechanism of Rhizoma Alismatis decoction on prevention and treatment of hyperlipemia,through investigating hepat-ic expressions of peroxisome proliferator activated re-ceptor-α(PPARα)and acyl CoA oxidase (ACO)in rats with hyperlipemia. Methods Fifty male Sprague-Dawley rats(160 ~ 180 g)were randomly divided into five groups:control group,model group,high-dose of Rhizoma Alismatis decoction group (H-RAD),low-dose of Rhizoma Alismatis decoction group(L-RAD), and Xue-Zhi-Kang group(XZK). Rats in control group were fed with ordinary forage,and the others were with high-fat forage,which lasted for four weeks. At the same time,high and low-dose of Rhizoma Alismatis decoction,as well as Xuezhikang capsule,was admin-istered in respectively designed groups. Then,the TC, TG,HDL and LDL of serum were detected,the mor-phology of liver tissues was observed with HE,and the expressions of PPARα and ACO were detected with RT-PCR and Western blot after four weeks. Results Rhizoma Alismatis decoction could significantly reduce serum concentration of TC,TG and LDL(P < 0. 01), while increasing the concentration of HDL(P < 0. 01) and strengthening the expressions of PPARα and ACO (P < 0. 01). Conclusion Strengthening the expres-sions of PPARα and ACO can be viewed as mecha-nisms of Rhizoma Alismatis decoction in prevention and treatment of hyperlipemia.
ABSTRACT
BACKGROUND: Tetracycline (TET) has been found to have both antibiotic and anti-inflammatory properties. The anti-inflammatory effect of topical TET on atopic dermatitis (AD) has not been reported. The purpose of this study was to explore the potential role of topical TET and its anti-inflammatory effects in a mouse model of AD. METHODS: The 2% TET was applied topically to ears of MC903-induced AD-like BALB/c mice once a day. AD-like symptoms and severity were evaluated by assessing skin scoring of dermatitis, ear thickness, and frequency of scratching. Serum IgE and thymic stromal lymphopoietin (TSLP) levels were measured by enzyme-linked immunosorbent assay. Western blot was used for analyzing the expressions of TSLP, protease-activated receptor 2 (PAR2), and nuclear factor-kappa B (NF-κB) in skin lesions. Real-time polymerase chain reaction was performed to assess the mRNA levels of TSLP and inflammatory cytokines including interleukin (IL)-4, IL-13, tumor necrosis factor (TNF)-α, and IL-1ß in skin lesions. RESULTS: Scoring of dermatitis (9.00 ± 0.63 vs. 6.67 ± 1.03, P = 0.001), ear thickness (0.44 ± 0.02 mm vs. 0.40 ± 0.03 mm, P = 0.018), and serum IgE level (421.06 ± 212.13 pg/ml vs. 244.15 ± 121.39 pg/ml, P = 0.047) were all improved in the 2% TET treatment group compared with AD group. Topical TET significantly reduced the serum level of TSLP (119.04 ± 38.92 pg/ml vs. 65.95 ± 54.61 pg/ml, P = 0.011) and both mRNA and protein expressions of TSLP in skin lesions compared with AD group (P = 0.003 and 0.011, respectively), and NF-κB and PAR2 expression in skin lesions were also suppressed (P = 0.016 and 0.040, respectively). Furthermore, expressions of inflammatory cytokines IL-4, IL-13, and TNF-α in skin lesions were down-regulated in 2% TET group compared with AD group (P = 0.035, 0.008, and 0.044, respectively). CONCLUSIONS: Topical TET exerted anti-inflammatory effects through suppression of TSLP and inflammatory cytokines in AD mouse model, suggesting TET as a potential agent for the topical treatment of AD in the future.

BACKGROUND: Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD. METHODS: A hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software. RESULTS: A total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients. CONCLUSION: Late-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.

BACKGROUND: Antimicrobial peptides, including cathelicidin LL-37, human beta defensin (HBD)-2, and HBD-3, are important elements of the innate immune response and involved in modulation of the adaptive immunity, and they also play an important role in cutaneous defense against Mycobacterium tuberculosis. METHODS: The fresh skin tissues and paraffin-embedded biopsy samples from three cutaneous tuberculosis, two tuberculids, and ten healthy individuals were collected. The expressions of LL-37, HBD-2, and HBD-3 mRNA in the lesions of three cutaneous tuberculosis and two tuberculids were detected by quantitative real-time polymerase chain reaction; the protein expressions were detected by immunohistochemistry and Western blotting methods. RESULTS: The expressions of LL-37 mRNA and protein in the lesions of cutaneous tuberculosis and tuberculids were similar to that of normal skin. The expression of HBD-2 mRNA had an increasing trend in the lesions of cutaneous tuberculosis and tuberculids compared with that of normal skin; however, the expression of HBD-2 protein in the lesions of cutaneous tuberculosis had a decreasing trend compared with that of normal skin, and the expression of HBD-2 protein in the lesions of tuberculids was similar to that of normal skin. The expressions of HBD-3 mRNA and protein in lesions of cutaneous tuberculosis and tuberculids were similar to that of normal skin. CONCLUSIONS: Our study indicated that the expression of HBD-2 and HBD-3 mRNA and protein in lesions of cutaneous tuberculosis may be not consistent with that of tuberculids. However, an inherent limitation of the present study was that the sample size was small, and the roles and regulation mechanisms of LL-37, HBD-2, and HBD-3 in cutaneous tuberculosis and tuberculids need to be further investigated.

A retrospective analysis was performed for clinical features, treatment process, duration of viral nucleic acid shedding, and prognosis.</p><p><b>RESULTS</b>The most common symptoms in these children were fever (89/90, 99%), cough (89/90, 99%), running nose (69/90, 77%), shortness of breath (26/90, 29%), and myalgia (23/90, 26%). The mean duration of viral nucleic acid shedding in 90 children was 9.4±2.9 days. The simple influenza A group had a significantly shorter duration of viral nucleic acid shedding than the influenza A-pneumonia, influenza A-nervous system damage, and influenza A-underlying disease groups (p<0.05), while there were no significant differences between the influenza A-pneumonia, influenza A-nervous system damage, and influenza A-underlying disease groups (p>0.05). The children who received antiviral therapy within 48 hours after disease onset had significantly shorter duration of viral nucleic acid shedding and time to body temperature recovery than those who received antiviral therapy more than 48 hours after disease onset (p<0.05). Of all the children with body temperature recovery, 83% still tested positive for viral nucleic acid.</p><p><b>CONCLUSIONS</b>Complications, underlying diseases, and timing of antiviral therapy are influencing factors for the duration of influenza A virus nucleic acid shedding, and whether body temperature returns to normal cannot be used to decide whether to continue antiviral therapy.</p>

Menopausal metabolic syndrome (MMS) is a series of syndrome caused by ovarian function decline and hormone insufficiency, and is a high risk factor for cardiovascular diseases (CVD) and type II diabetes mellitus (T2DM). Erzhiwan (EZW), composed of Herba Ecliptae and Fructus Ligustri Lucidi, is a traditional Chinese herbal formula that has been used to treat menopausal syndrome for many years. We added Herba Epimedii, Radix Rehmanniae, and Fructus Corni into EZW, to prepare a new formula, termed Jiawei Erzhiwan (JE). The present study was designed to determine the anti-MMS effects of JE using ovariectomized (OVX) adult female rats that were treated with JE for 4 weeks, and β-tc-6 cells and INS cells were used to detected the protect effectiveness of JE. Our results showed JE could increase insulin sensitivity and ameliorated hyperlipidemia. Metabolomics analysis showed that the serum levels of branched and aromatic amino acids were down-regulated in serum by JE administration. Moreover, JE enhanced the function of islet β cells INS-1 and β-tc-6, through increasing the glucose stimulated insulin secretion (GSIS), which was abolished by estrogen receptor (ER) antagonist, indicating that JE functions were mediated by ER signaling. Additionally, JE did not induce tumorigenesis in rat mammary tissue or promoted proliferation of MCF-7 and Hela cells. In conclusion, our work demonstrated that JE ameliorated OVX-induced glucose and lipid metabolism disorder through activating estrogen receptor pathway and promoting GSIS in islet β cells, thus indicating that JE could be a safe and effective medication for MMS therapy.

Objective To investigate the correlation between large platelet ratio (P-LCR) and stroke in patients with atrial fibrillation. Methods 152 consecutive patients with atrial fibrillation were selected and divided into two groups according to whether accompanying stoke or not. Clinical features of patients and blood test indicator P-LCR were analyzed by Logistic regression analysis. Results In total, 152 subjects, including 47 patients with stoke and 105 patients without stoke,were included in the study. Univariate analysis showed that the difference in age, diabetes, hypertension, lipid-lowering therapy and P-LCR between two groups was statistically significant (P < 0.05). Logistic regression analysis showed that age, diabetes and P-LCR were independent risk factors of stroke in patients with atrial fibrillation. Conclusions Age, diabetes and P-LCR are independent risk factors of stroke in patients with atrial fibrillation.
