To analyze the clinical characteristics and treatment status of atopic dermatitis (AD) in children in the outpatient department of a children's hospital in Beijing from 2015 to 2019. This study used a cross-sectional study method to retrospectively analyze the data of AD patients who visited the Dermatology outpatient department of Beijing Children's Hospital, Capital Medical University, from April 2015 to April 2019. A total of 1 926 AD patients aged 0-17.5 years old living in Beijing and its surrounding areas were included, and the general situation, severity and distribution of AD disease, clinical characteristics and severity of AD, relevant influencing factors of AD onset, AD disease prognosis and treatment status were recorded. SAS 9.4, SPSS19.0, and R software were used for data processing, and descriptive statistical analysis, Chi-square test, Analysis of Variance, and correspondence analysis were used for statistical analysis. The results showed that the male to female ratio of AD patients in children included in this study was 1.4∶1; 79.0% (1 522/1 926), 86.1%(1 658/1 926), 91.3%(1 758/1 926), and 97.3%(1 907/1 926) of AD onset at the age of 6 months, 1 year, 2 years, and 5 years, respectively; mild of AD patients accounted for 13.2% (255/1 926)(SCORAD score 0-24), moderate of AD patients accounted for 50.1%(965/1 926) (SCORAD score 25-50), and severe of AD patients accounted for 36.7% (706/1 926)(SCORAD score>50).The age of severe AD patients were younger than mild and moderate AD patients. The face, head, trunk, and lower limbs were common areas of onset for moderate to severe AD, while the hands, feet, and ears were common areas of onset for severe AD patients. Temperature changes, hot water factors, mental and emotional states, and spring and winter were the main aggravation factors of AD;35.2% (678/1 926) aggravated and 61.8% (1 191/1 926) persistent. The more frequent bathing, the less severity of AD disease (χ²=29.791,P<0.001); 28.0% (520/1 856) of AD patients have no moisturizing habits, which were correlated with the severity of AD disease (χ²=15.908, P<0.05); the proportion of combined treatment medications in children with moderate to severe AD was significantly higher than mild AD patients. In conclusion, the patients with AD who went to specialist clinics were mainly moderate to severe patients and developed disease before the age of 5 years from 2015 to 2019.The severity of AD were mainly moderate to severe, and most of these patients had poor disease control. Traditional treatment plans had limitations. Identifying the clinical characteristics and treatment status of childhood AD would help us to carry out more targeted prevention and management work.

AIM: To evaluate the effect of 0.02% mitomycin-C(MMC)on the corneal density after transepithelial photorefractive keratectomy(Trans-PRK). METHODS: Retrospective case analysis. Selected 28 patients with 56 eyes in moderate myopia who underwent Trans-PRK surgery from January 2021 to June 2021 in our hospital. They were divided into MMC group in 28 eyes with a combination of 0.02% MMC 20s during the surgery and the control group in 28 eyes was not use MMC during the surgery. The Pentacam anterior segment analyzer was used to measured the corneal density in different diameter ranges and different thickness layers before and after surgery at 14d, and after surgery at 1 and 3mo.RESULTS: The total corneal density value of MMC group was 16.60(15.70,17.10 )before the surgery, after the surgery at 14d was 16.63(15.90,17.50 ), at 1mo was 16.57(15.10,16.70 ), at 3mo was 16.04(14.60,16.60 ). The total corneal density value of control group was 16.30(15.50,17.30 )before the surgery, after the surgery at 14d was 16.20(15.20,17.10 ), at 1mo was 16.08(14.90,16.40 )and at 3mo was 15.60(14.60,16.40 ). In the zone of 0-2mm diameter was centered on the corneal vertex, the corneal density of the two groups at 14d after the surgery was higher than those before surgery(P<0.001 ). In the zone of 2-6mm diameter, the corneal density of the two groups at 1mo and 3mo after surgery was higher than those before the surgery(P<0.001). In the zone of 6-10mm, the corneal density of the two groups at 14d, 1 and 3mo after surgery was higher than those before the surgery(P<0.001). In the layer of anterior 120 μm, the corneal density of the two groups at 1mo and 3mo after the surgery was decreased than that before surgery(P<0.01). In the middle layer, the corneal density of the two groups at 1mo after the surgery was decreased than those before surgery(P<0.01).CONCLUSION:The use of 0.02% MMC during the operation can reduce the corneal density and increase the corneal light transmittance in the early postoperative period. The occurrence and prognosis of haze can be effectively quantified by observing the changes of corneal optical density in different ranges in different time periods after operation.

OBJECTIVE: To observe the therapeutic effects of different waves of electroacupuncture (EA) on knee osteoarthritis (KOA), and to explore the mechanism of different waves of EA on promoting cartilage repair. METHODS: Ninety- seven patients with KOA were randomly divided into a dilatational wave group (32 cases, 2 cases dropped off), a continuous wave group (32 cases, 2 cases dropped off) and a discontinuous wave group (33 cases, 3 cases dropped off). The same acupoints of Xuehai (SP 10), Liangqiu (ST 34), Dubi (ST 35) and Neixiyan (EX-LE 4) were selected in the three groups. The dilatational wave (frequency of 2 Hz/10 Hz) was used in the dilatational wave group, the continuous wave (frequency of 10 Hz) was used in the continuous wave group, and the discontinuous wave (frequency of 10 Hz) was used in the discontinuous wave group. All the needles were retained for 30 min. All the treatment was given 3 times a week (on Monday, Wednesday and Friday) for 4 weeks. Lysholm knees scoring scale (LKSS) was used to evaluate the knee joint function before and after treatment, and the content of transforming growth factor-β1 (TGF-β1) in the joint effusion before and after treatment was determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: Compared before treatment, the total score and each score of LKSS were increased after treatment in the three groups (all <0.05). The improvements of total score, pain score, instability score, swelling score of LKSS in the continuous wave group and the dilatational wave group were superior to those in the discontinuous wave group (all <0.05). The content of TGF-β1 in the joint effusion in each group was increased after treatment (<0.05), and the improvement in dilatational wave group was superior to thoes in the continuous wave group and the discontinuous wave group (all <0.05). CONCLUSION The three different waves of EA could all improve the clinical symptoms of KOA, which may promote cartilage repair by increasing TGF-β1 content. The dilatational wave had the best overall effect, which can be used as a clinical optimal treatment.

Objective To investigate the effect of 1 800 MHz electromagnetic radiation on activity of SOD and GSH－Px in the skin tissues of SD rats.Methods A total of 98 healthy SD rats with SPF level,aged 4 weeks, were randomly divided into radiation group and control group.The radiation group was totally exposed under 1 800 MHz electromagnetic wave with seven different power density of radiation of 0.1 mW/cm2,0.3 mW/cm2,0.5 mW/cm2 , 0.7 mW/cm2, 0.9 mW/cm2, 1.0 mW/cm2and 1.2 mW/cm2respectively.It lasted 21 days and for a period of 12 hours a day. After radiation,the activity of SOD and GSH－Px in the skin tissues were detected by enzyme marker. Results In radiation group,the activity of SOD and GSH－Px in the skin tissues of SD rats were decreased under 0.3 mW/cm2and 0.5 mW/cm21 800 MHz electromagnetic wave. Compared with the control group, there was a significantly difference in radiation group (P＜0.05) .While under other four 1 800 MHz electromagnetic waves, the activity of GSH－Px and SOD in the skin tissues showed no statistical difference between the two groups (P＞0.05) . Under 1 mW/cm21 800 MHz electromagnetic wave, the activity of GSH－Px showed no statistical difference between two groups (P＞0.05) . Conclusion The power density of 0.3 mW/cm2and 0.5 mW/cm21 800 MHz electromagnetic wave can reduce the activity of GSH－Px and SOD in the skin tissues of rats.

PURPOSE: Little is known about combination of the circulating Epstein-Barr viral (EBV) DNA and tumor volume in prognosis of stage II nasopharyngeal carcinoma (NPC) patients in the intensity modulated radiotherapy (IMRT) era. We conducted this cohort study to evaluate the prognostic values of combining these two factors. MATERIALS AND METHODS: By Kaplan-Meier, we compare the differences of survival curves between 385 patients with different EBV DNA or tumor volume levels, or with the combination of two biomarkers mentioned above. RESULTS: Gross tumor volume of cervical lymph nodes (GTVnd, p < 0.001) and total tumor volume (GTVtotal, p < 0.001) were both closely related to pretreatment EBV DNA, while gross tumor volume of nasopharynx (GTVnx, p=0.047) was weakly related to EBV DNA. EBV DNA was significantly correlated with progress-free survival (PFS, p=0.005), locoregional-free survival (LRFS, p=0.039), and distant metastasis-free survival (DMFS, p=0.017), while GTVtotal, regardless of GTVnx and GTVnd, had a significant correlation with PFS and LRFS. The p-values of GTVtotal for PFS and LRFS were 0.008 and 0.001, respectively. According to GTVtotal and pretreatment EBV DNA level, patients were divided into a low-risk group (EBV DNA 0 copy/mL, GTVtotal < 30 cm³; EBV DNA 0 copy/mL, GTVtotal ≥ 30 cm³; or EBV DNA > 0 copy/mL, GTVtotal < 30 cm³) and a high-risk group (EBV DNA > 0 copy/mL, GTVtotal ≥ 30 cm³). When patients in the low-risk group were compared with those in the high-risk group, 3-year PFS (p=0.003), LRFS (p=0.010), and DMFS (p=0.031) rates were statistically significant. CONCLUSION: Pretreatment plasma EBV DNA and tumor volume were both closely correlated with prognosis of stage II NPC patients in the IMRT era. Combination of EBV DNA and tumor volume can refine prognosis and indicate for clinical therapy.

To establish a genetic susceptibility assessment model of lung cancer risk potentially associated with polycyclic aromatic hydrocarbon (PAH) inhalation exposure among non-smokers in China, a total of 143 patients with lung adenocarcinoma and 143 cancer-free individuals were recruited. Sixty-eight genetic polymorphisms in 10 pathways related to PAH metabolism and tumorigenesis were selected and examined. It was observed that 3 genetic polymorphisms, along with 10 additional genetic polymorphisms via gene-gene interactions, significantly influenced lung cancer risk potentially associated with PAH inhalation exposure. Most polymorphisms were associated with PAH metabolism. According to the established genetic susceptibility score (GSS), lung cancer risk increased with a rise in the GSS level, thereby indicating a positive dose-response relationship.

Objective To provide reference for cervical cancer control by compare the HPV infection rate and distribution Xianyang and Baoji area.Methods Analysed HPV subtypes results of 1 356 cases in Baoji area and 7 708 cases in Xianyang area,and compared the age distribution,subtypes and positive rate of HPV infection in the women of the two areas.Results The HPV positive rate was 35.91% in Baoji area,and 32.14% in Xianyang area respectively.The most popular single subtype was HPV16,58,52 in the two areas.The dual-infection was most popular was HPV multiple infection in the two ar-eas.The HPV81 and HPV73 were not detected out in Baoji area,and all 23 HPV subtypes were detected out in Xianyang ar-ea.Conclusion The HPV infection rate in Baoji was higher than Xianyang(P<0.01).The high-risk HPV subtypes were same in the two areas.The HPV positive rate was high in all age groups.

Objective To comparatively analyze the clinical characteristics of thyrotropin-secreting pituitary adenomas (TSH-omas).Methods The clinical features, laboratory variables, imaging and pathological Results were retrospectively compared and analyzed of 26 cases with TSH-omas admitted in Chinese PLA General Hospital from Feb. 2006 to Oct. 2016 and 20 cases with TSH-omas admitted in Shanghai Huashan Hospital from Apr. 2006 to Apr. 2013.Results The female ratio was slightly higher in patients of Chinese PLA General Hospital than in Huashan Hospital [(57.7%(15/26)vs. 45.0%(9/20)], while the mean age was similar [39.5±14.1(18-67 years)vs. 40.0±14.5(17-74 years)]. The most common chief complaint was thyrotoxicosis [73.1%(19/26)vs. 55.0%(11/20)], and mild-to-moderate goiter was the most common symptom. The mean serum TSH levels in Chinese PLA General Hospital and in Huashan Hospital were 5.06(2.97-6.27)mU/L and 6.16(3.76-10.91)mU/L respectively, and patients with normal serum TSH levels were more common in Chinese PLA General Hospital than in Huashan Hospital [57.7%(15/26)vs. 40.0%(8/20)]. Microadenoma was more common in Chinese PLA General Hospital than in Huashan Hospital [34.62%(9/26)vs. 20.0%(4/20)], while macroadenoma was more common in Huashan Hospital than in Chinese PLA General Hospital [20.0%(4/20)vs. 7.7%(2/26)]. Microadenoma was more common in female patients of the both groups [66.7%(6/9)vs. 75.0%(3/4)], while macroadenoma was all found in male patients. Tumor invasion of surrounding tissue and structure was often found in macroadenoma. In terms of octreotide inhibition test, the range of 24h TSH inhibition rate was roughly the same in the two groups (37.4%-91.8% and 46.5%-94.1%, respectively). Mixed adenoma was rare among all the pathologically confirmed cases. In Chinese PLA General Hospitals, TSH immunoreactive negative neoplastic cells were found in 3 of 8 cases, and octreotide scanning showed negative in 2 of 12 cases.Conclusions Patients with TSH-omas in the two hospitals show similarities but also some significant differences in the clinical features. Overall, the domestic patients with TSH-omas are diagnosed without gender difference according to the reports in China. The mean age at diagnosis is significantly younger than that in foreign data. Microadenoma is more common in females, while macroadenoma is more common in males. Serum TSH levels can be normal in patients with TSH-omas. Immunostaining and/or octreotide scanning for TSH can be negative.

Objective To analyze the relationship between the brain functional alterations of patients with Cushing's disease (CD) and patients' mental symptom by applying the Evaluating Emotional Scales and task functional magnetic resonance imaging (Task fMRI).Methods Task fMRI was performed on 8 patients with diagnosed CD admitted in the Department of Endocrinology of Chinese PLA General Hospital from Nov. 2015 to Nov. 2016 and 21 healthy people with matched age, gender and education level as control. Meanwhile, Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Positive and Negative Affective Scale (PANAS) and Cushing Quality of Life Scale (Cushing QOL) were obtained to assess the brain functions.Results Significant depression and anxiety were observed in patients with CD, and their positive affective score was substantially lower while the negative affective score was relatively higher compared with that in the controls. Task fMRI revealed that, when watching the positive pictures, the activation degree of left cerebellum and right postcentral gyrus weakened in CD patients than in the controls, and the positive correlations existed between the activation degree of left cerebellum and the 16 o'clock adrenocorticotrophic hormone (ACTH) level, and between the activation degree of right postcentral gyrus and the urinary free cortisol (UFC) level in CD patients. In contrast, when watching the negative pictures, the activation degree of left cerebellum, bilateral parahippocampal gyrus and left inferior frontal gyrus was weakened in CD patients than in the controls, and the activation degree of left cerebellum was negatively correlated to the 0 o'clock cortisol level and SAS score, but is positively correlated to the UFC level. When watching the neutral pictures, the activation degree of left cerebellum and left parahippocampal gyrus was weakened in CD patients than in the controls.Conclusions CD patients may have impaired brain function with depression and anxiety mental symptoms. By Task fMRI, it can be found that the weakened activation degree of left inferior frontal gyrus, right postcentral gyrus, bilateral parahippocampal gyrus and left cerebellum may be related to CD patients' mental symptoms.
