ABSTRACT
Objective:To investigate the correlation between food-specific IgG (sIgG) antibodies and phenotypes of chronic spontaneous urticaria (CSU) .Methods:Serum samples were collected from outpatients with active CSU, symptomatic dermographism (SD) , or acute urticaria (AU) , and healthy controls from 5 third-grade class-A hospitals such as the First Hospital of China Medical University between April 2014 and March 2015. Enzyme-linked immunosorbent assay was conducted to detect serum levels of 90 food-sIgG antibodies and total IgE, Western blot analysis to detect levels of 20 allergen-specific IgE antibodies, and chemiluminescent microparticle immunoassay to detect levels of anti-thyroid peroxidase IgG antibodies and anti-thyroglobulin IgG antibodies. Comparisons of normally distributed quantitative data between two groups and among several groups were performed by t test and one-way analysis of variance, respectively; comparisons of non-normally distributed quantitative data between two groups were performed by Mann-Whitney U test; for comparisons of proportions, chi-square test and Fisher′s exact test were used. Results:A total of 248 patients with CSU, 22 with SD, 15 with AU and 13 healthy controls were recruited. The cut-off level for sIgG positivity was 100 U/ml (at least 2+) , and the positive rate of food-sIgG antibodies was slightly higher in the patients with CSU (176/248, 70.97%) , SD (15/22, 68.18%) and AU (11/15) than in the healthy controls (7/13; χ2 = 1.80, P = 0.615) . Among the 248 CSU patients, the proportion of patients with family history of allergic diseases was significantly higher in the sIgG-positive group (71/176, 40.34%) than in the sIgG-negative group (19/72, 26.39%; χ2 = 4.30, P = 0.042) , while no significant difference was observed in the 1-day urticaria activity score (UASday) between the two groups ( Z = 0.18, P = 0.859) . Totally, 177 CSU patients completed 12- to 40-week treatment; their condition could be completely controlled by second-generation H1-antihistamines, and there was no significant difference in the required dosage of second-generation H1-antihistamines between the sIgG-positive group (128 cases) and sIgG-negative group (49 cases; Z = -1.06, P = 0.298) . Conclusions:The prevalence of family history of allergic diseases was relatively high in food-sIgG-positive patients with CSU. However, food-sIgG could not be used as an indicator to reflect the disease activity of CSU and treatment response.
ABSTRACT
Objective:To investigate the efficacy of drug combined moisturizerand sunscreen with Prinsepia utilis oil and purslane in the treatment of chronic actinic dermatitis.Methods:From May 2017 to August 2018, 216 cases of chronic actinic dermatitis admitted to the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University were divided into 4 groups. The 54 cases of control group was treated by oral administration of ebaxtin discontinued and hydroxychloroquine sulfate tablets for 4 weeks. The external use of desonide cream for 2 weeks. On this basis, the 56 cases of first treatment group used topical moisturizer twice a day, and topical sunscreen once a day; only topical moisturizer was used in 54 cases of second treatment group, twice a day; the 52 cases of third treatment group only used topical sunscreen once a day. Patients were followed up at 2, 4 and 6 weeks after treatment, respectively. The eczema area and severity index were detected to evaluate curative effect, and skin lesions water, trans epidermal water loss and content of lipid in the four groups of patients; reflective confocal microscope was used to observe the inflammatory reaction, blood vessels in skin lesions and so on.Results:After 6 weeks treatment, the efficacy rate of 54 cases in the first treatment group (85.2%) was significantly higher than that of 56 cases in the second treatment group (62.5%), 54 cases in the third treatment group (64.8%), 52 cases in the control group (50.0%), and the difference was statistically significant ( P<0.05). Non-invasive skin test results showed that the transepidermal water loss of the three groups was 16.42±8.64, 21.59±12.34 and 19.79±11.79, respectively, which was significantly lower than that before treatment (38.76±12.59, 38.37±14.48, 39.2±13.93). and the skin water content (42.15±10.25, 35.5±12.91, 33.42±12.83) and lipid content (37.96±11.16, 31.5±8.31, 34.09±12.51), compared with the pre-treatment skin water content (21.30±11.04, 16.86±10.88, 14.73±12.00) and lipid content (13.64±10.10, 15.67±12.60, 9.42±7.75) significantly increased, the difference was statistically significant ( P<0.05). The improvement of spongiosis (0.97±0.68), disruption of honycomb pattern and (0.82±0.77) and vascular dilatation (1.03±0.73) under reflective confocal microscope was better in first treatment than that in the second treatment (1.51±0.56, 1.0±0.77, 1.31±0.68). and the third treatment (1.35±0.85, 1.35±0.85, 0.97±0.80), and the control group (1.85±0.74, 1.85±0.74, 1.53±0.61). The difference was statistically significant ( P<0.05). Compared with the second treatment, the third treatment and control group, transepidermal water loss in the first treatment was significantly decreased, and epidermal water content and lipid content were significantly increased, with statistically significant difference ( P<0.05). Conclusions:The efficacy of drugs combined with moisturizer and sunscreen in the treatment of chronic actinic dermatitis is significantly better than that of simple drug therapy and drugs with topical moisturizer or sunscreen. It suggests that in the treatment of chronic actinic dermatitis, it is not only necessary to be anti-inflammatory, anti-photosensitive treatment, but also need to pay attention to moisturize and sun protection.

ABSTRACT
<p><b>BACKGROUND</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>

Objective To evaluate the efficacy and safety of hydroxychloroquine combined with butyli flufenamatum ointment and other drugs for the treatment of polymorphous light eruption (PLE).Methods A total of 48 patients with PLE were randomly and equally classified into group 1 and group 2.Both groups took hydroxychloroquine 200 mg twice a day and loratadine 10 mg per day for the initial 4 weeks,then took hydroxychloroquine 100 mg twice a day alone for another 4 weeks.Group 1 also topically applied butyli flufenamatum ointment twice a day during the 8 weeks,while group 2 applied mometasone furoate cream twice a day for the first 2 weeks followed by butyli flufenamatum ointment twice a day for another 6 weeks.Each treatment cycle lasted 2 weeks,and both groups received 4 cycles of treatment.Patients were evaluated for the response rate at the end of each cycle,and for the total symptom score and erythema score before and after the 8-week treatment.Statistical analysis was carried out using t test,chi-square test,Fisher's exact test and repeated-measures analysis of variance with the SPSS17.0 software.Results On day 14,28,42 and 56,the total score improved in 0,3,12 and 19 patients in group 1 respectively,and in 1,4,12 and 20 patients in group 2 respectively;the erythema score improved in 1,5,13 and 18 patients in group 1 respectively,and in 0,5,11 and 17 patients in group 2 respectively.No significant difference was observed between the two groups in response rates at any of the above four time points (P ＞ 0.05).Both the total score and erythema score significantly decreased after the 8-week treatment in both groups compared with the pretreatment scores (both P ＜ 0.05).No serious adverse reaction was observed in either of the two groups.Conclusions Hydroxychloroquine combined with loratadine and butyli flufenamatum ointment shows high efficacy and safety for the treatment of PLE.Topical butyli flufenamatum ointment is highly effective for the treatment of PLE,especially for PLE cases mainly presenting with erythema.
ABSTRACT
Taenia pisiformis is one of the most important parasites of canines and rabbits. T. pisiformis cysticercus (the larval stage) causes severe damage to rabbit breeding, which results in huge economic losses. In this study, the genetic variation of T. pisiformis was determined in Sichuan Province, China. Fragments of the mitochondrial cytochrome b (cytb) (922 bp) gene were amplified in 53 isolates from 8 regions of T. pisiformis. Overall, 12 haplotypes were found in these 53 cytb sequences. Molecular genetic variations showed 98.4% genetic variation derived from intra-region. F(ST) and Nm values suggested that 53 isolates were not genetically differentiated and had low levels of genetic diversity. Neutrality indices of the cytb sequences showed the evolution of T. pisiformis followed a neutral mode. Phylogenetic analysis revealed no correlation between phylogeny and geographic distribution. These findings indicate that 53 isolates of T. pisiformis keep a low genetic variation, which provide useful knowledge for monitoring changes in parasite populations for future control strategies.

<p><b>OBJECTIVE</b>To investigate the effect of phenylhexyl isothiocyanate (PHI) on histone acetylation and apoptosis in hepatocellular carcinoma cell line (SMMC-7721) in vitro.</p><p><b>METHODS</b>The viability of SMMC-7721 cells was determined by trypan blue exclusion. Apoptotic cells were assessed by TUNEL assay. The proteins of Bcl-2, Procaspase-9, Procaspase-8, Procaspase-3, caspase-9, caspase-3, histone acetylated H3 and H4 were detected by Western blot.</p><p><b>RESULTS</b>Compared with the vehicle control, PHI at 5, 10, 20, 40 and 80 µmol/L reduced the cell viability of SMMC-7721 cells in a concentration-dependent manner. PHI induced apoptosis in SMMC-7721 cells. An increased amount of apoptotic cells was detected after 7 hours exposure to PHI at 10, 20, and 40 µmol/L, 6.9% ± 2.4%, 17.5% ± 4.2% and 54.5% ± 5.4%, respectively, while that of the vehicle control was 4.5% ± 2.3% (P < 0.05). Along with the prolongation of time and increase of dose, the expressions of bcl-2, procaspase-9, procaspase-3 were decreased, that of caspase-9 and caspase-3 was increased. In contrast, alteration of procaspase-8 was not significant at those concentrations. PHI accumulated acetylated histone H3 and H4. After 3 hours exposure to PHI at 10, 20 and 40 µmol/L, the level of histone acetylated H3 was 1.87-, 2.43-, 3.67-fold increased and histone acetylated H4 was 1.29-, 1.45-, and 2.25-fold increased, compared with that of the vehicle control. The protein of histone acetylated H3 and H4 was significantly accumulated after 7 hours exposure.</p><p><b>CONCLUSION</b>PHI is a new histone deacetylation inhibitor. It may induce accumulation of histone acetylation H3 and H4, inhibit cell growth and induce apoptosis in SMMC-7721 cells via the mitochondrial pathway.</p>

<p><b>OBJECTIVES</b>To investigate the changes in intrahepatic portal systemic shunt flow (IHSF) and their relationship with microspheres induced acute portal hypertension.</p><p><b>METHODS</b>Following acute intrahepatic presinusoidal obstruction by intraportal injection of 15 microm diameter microspheres in male Wistar rats, functional hepatic blood flow (FHBF) and IHSF were determined by hepatic sorbitol uptake methods. The percentage of large shunts of diameter > 15 microm were estimated by intraportal injection of 51Cr labeled 15 mum diameter microspheres.</p><p><b>RESULTS</b>In normal control rats, hepatic sorbitol uptake was 97.9%+/-0.5% and IHSF was negligible, with FHBF equaling total hepatic blood flow [(2.52 +/- 0.23) ml/min x 100 g body weight-1]. Microsphere injection decreased sorbitol uptake to 12.8% +/- 4.3% and further to 4.1% +/- 0.7% when followed by hepatic arterial ligation. In the latter two groups, IHSF (1.46 +/- 0.15 and 1.16 +/- 0.19 ml/min x 100 g body weight-1, respectively) was not significantly different from portal venous flow [(1.36 +/- 0.20) and (1.20 +/- 0.20) ml/min x 100 g body weight-1, respectively; t = 2.013 and t = 2.116]. Portal venous flow remained at 70% of basal values and portal venous pressure only increased by 50% from baseline. 51Cr labeled microsphere shunt fraction through large shunts (> 15 microm) was less than 1.0%.</p><p><b>CONCLUSION</b>Intrahepatic portasystemic shunts in the normal rat liver predominantly have diameters less than 15 microm and, when activated by intraportal injection of microspheres, they divert up to 70% of portal venous blood flow away from hepatic sinusoids and thereby they reduce acute increases in portal venous pressure.</p>
