ABSTRACT
Objective:To compare the efficacy between acupuncture and acupuncture with infrared thermography-guided Chinese massage (Tuina) in treatment of children with Bell′s palsy (BP).Methods:Seventy two children with BP admitted to the Rehabilitation Department of Beijing Children′s Hospital from October 2019 to April 2020 were randomly assigned into two groups: 35 cases were treated with acupuncture alone (acupuncture group) and 37 cases received acupuncture combined with Tuina for treatment (combination group). In combination group, the temperature of forehead, cheek and mandible areas was examined by infrared thermography before each course. Compared healthy side if the temperature on the affected side was lower, higher or the same, rubbing method, tapping method and one-finger meditation push method of Tuina was applied, afterwards the acupuncture treatment was given as in the acupuncture group. Patients in both groups were treated once a day with 5 days for a course and a total of 3 courses. The patients were assessed with House-Brackmann (H-B) facial nerve function evaluation scale and Portmann simple score scale before and after each course of treatment.Results:The H-B classification of the two groups of children at the end of the third course of treatment was significantly better than that before treatment (χ2=31.01, 56.41; P<0.01). There was no significant difference in H-B grading between the two groups before treatment, after the first and second course (χ2=0.58, 8.49, 6.79; P>0.05). After the third course of treatment, the H-B grading assessment of the combination group was significant better than that of the acupuncture group (χ2=10.03, P<0.05). The Portmann scores of the two groups were improved after each course of treatment ( F=9.68, 22.54; P<0.01); however, the facial nerve function of combination group was improved more significantly than that of acupuncture group [(13.97±4.58) vs.(10.97±5.40), t=2.55, P=0.01]. The total effective rate of combination group was higher than that of acupuncture group [51.35% (19/37) vs. 20.00% (7/35), χ2=6.79, P<0.05]. There was a significant difference in the application frequency of three Tuina methods among the forehead, cheek and mandibular areas in the first course and the third course (χ2=21.23, 13.33; P<0.05). In the same area (forehead, cheek and mandible) there was a significant difference in the application frequency of three massage techniques among the three courses of treatment (χ2=31.26, 21.35, P<0.01). Conclusion:With the guidance of infrared thermal imaging, individualized Chinese massage (Tuina) combined with acupuncture treatment is more effective in treatment of children with Bell′s palsy than using acupuncture alone.
ABSTRACT
Objective To find the rational selection of specimens for the detection of Epstein-Barr virus ( EBV ) DNA.Methods A total of 117 patients were diagnosed with EBV infection at Beijing Friendship Hospital from January to June 2017, including 44 patients with infectious mononucleosis (IM), 36 patients with EBV-associated hemophagocyticlymphohistiocytosis ( HLH ) and 37 patients with post-transplant lymphoproliferative disorders (PTLD).Patients were aged from 6 months to 28 years.EBV DNA loads (median and quartile) in peripheral blood mononuclear cells (PBMC) and plasmawere detected by real-time quantitative PCR.The viral loads of different specimen types were compared by nonparametric rank sum test ( Mann-Whitney test, M-W test) .Spearman correlation analysis was performed for correlation analysis.Results TheEBV DNA loads in PBMC of IM and PTLD were 53600 (7875,626500) copies/ml and 114000 (3396,590500) copies/ml, which were significantly higher than those in plasma [4500 (675, 8600)copies/ml and 0(0, 0)copies/ml, respectively].The M-W values were 372.5 and 30.5 respectively (both P<0.001), which indicated statistically significant differences .However, the EBV DNA loads in PBMC and plasma of HLH were 5100 (1425, 170000) copies/ml and 13500 (1303, 152500) copies/ml.The M-W value was 646.5 (P=0.991), which indicated no statistically significant difference . Spearman correlation analysis showed good correlations of EBV DNA loads between PBMC and plasmain IM and HLH, and the r values were 0.548 and 0.400, respectively (both P<0.05), while the correlation of EBV DNA loads between PBMC and plasma in PTLD was poor , and the r value was 0.308 ( P>0.05 ) . Conclusions For the diagnosis and monitoring of EBV infection , the types of specimens recommended by different diseases are different .Plasma or serum specimens are recommended for quantitative detection of EBV DNA in IM and HLH, while PBMC and plasma specimens are recommended in PTLD .Clinically, the type of specimen should be chosen reasonably according to the type of disease .

ABSTRACT
Objective To examine the interleukin-27 (IL-27) levels in the serum of the patients with neuromyelitis optica (NMO) and healthy controls (HCs) and explore the correlation of the serum IL-27 level with disease severity.Methods Serum concentrations of IL-27 from 39 patients with NMO and 39 HCs were measured by using enzyme-linked immunosorbent assay (ELISA).Mann-Whitney U test was performed to analyze the difference in the IL-27 levels between the NMO group and the HCs.Spearman's rank correlation analysis was used to analyze the correlations of serum IL-27 levels with clinical parameters (EDSS,spinal cord lesion length,annual relapse rate and antibody titers of AQP-4) of NMO.Results The serum IL-27 levels were significantly lower in NMO group than in HCs (P＜0.001).Serum IL-27 levels were negatively correlated with EDSS,total length of spinal cord lesion identified by MRI at the sampling,and the average relapse rate during two-year follow-up (r=-0.439,P=0.010;r=-0.434,P=0.006;r=-0.451,P=0.031).There was no significant correlation between IL-27 levels and antibody titers of AQP-4 (r=-0.027,P=0.871).Multivariate regression analysis showed that serum IL-27 levels were negatively correlated with EDSS (B=-0.025,P=0.023).Conclusion IL-27 may participate in the pathogenic process of NMO and might be a prognosis marker of the disease.

ABSTRACT
Objective:To investigate whether the mindfulness training can reduce the aggression level and im-prove the sleeping quality among incarcerated people.Methods:Fifty-four male criminals were recruited into the study.They were divided into mindfulness training group (n =25)and control group (n =29).The training group took mindfulness exercise once a week for 6 weeks.While the participants in waiting list control group waited for 6 weeks without intervention.After 6-week mindfulness training for training group and post-assessment for all partici-pants,the waiting list control group went into 6-week mindfulness training.The Five Facet Mindfulness Question-naire (FFMQ),Aggression Questionnaire (AQ)and Pittsburgh Sleep Quality Index (PSQI)were assessed before and after the intervention.Results:There were 19 valid data in training group,and 21 in control group.After 6-week training,the score difference between pre-and post-assessment of FFMQ (P <0.01 )was higher in the training group than in the control group,and the difference of AQ (P <0.01)and PSQI (P <0.01)was lower in training group than in the control group.Conclusion:The results suggest that 6-week mindfulness training could effectively reduce the aggression level and improve the sleep quality in the long-term incarcerated males.
ABSTRACT
Objective To detect the expression of the transcription factor CCAAT/enhancer-binding protein alpha (C/EBP-α) in the epidermis of psoriasis vulgaris lesions,and to investigate its correlation with abnormal keratinocyte proliferation and disease severity.Methods Biopsy specimens were obtained from the lesions of 30 patients with psoriasis vulgaris and normal skin of 30 healthy human controls.A two-step immunohistochemical procedure was performed to detect the expressions of C/EBP-αt and Ki-67 in these specimens,and Western blot to quantify the expression of C/EBP-α.The proliferation index of keratinocytes was calculated according to the expression intensity of Ki-67.Statistical analysis was carried out by using the SPSS 17.0 software,and Pearson correlation analysis was conducted to assess the relationship of C/EBP-α expression level with proliferation index of keratinocytes and psoriasis area and severity index (PASI) score.Results C/EBP-α was predominantly expressed in the cytoplasm of keratinocytes,while Ki-67 in the nuclei of keratinocytes.Compared with the normal skin,the psoriatic lesions showed a significantly lower expression of Ki-67 (t =7.82,P ＜ 0.05),but higher proliferation index of keratinocytes (t =4.54,P ＜ 0.05).The expression level of C/EBP-α was negatively correlated with the proliferation index of keratinocytes and PASI score in the patients (both P ＜ 0.05).Western blot also showed an obvious decrease in the expression of C/EBP-α in psoriatic lesions.Conclusions The expression of C/EBP-α is decreased in lesions of psoriasis vulgaris,which might be involved in the pathogenesis of psoriasis vulgaris.
ABSTRACT
Activation of the innate immune system requires recognition of pathogen-associated molecular patterns, such as NOD-like receptors. The NOD-like receptor protein 3 (NLRP3) inflammasome is involved in induction of the pro-inflammatory cytokine, IL-1beta, and subsequent inflammatory responses. NLRP3 inflammasome plays important roles in the inflammatory and innate immune responses associated with autoimmune/inflammatory syndrome. However, analysis of the tissue distribution and expression profiles in BALB/c mice is still incomplete. In this study, we investigated the tissue distribution and expression pattern of NLRP3 in BALB/c mice to further elucidate its function in innate immunity in this commonly used laboratory animal model. NLRP3 mRNA expression levels and tissue distribution of the protein were investigated by real-time quantitative PCR and immunohistochemical analyses, respectively. NLRP3 mRNA expression was higher in the kidney and inguinal lymph nodes than in other tissues. Cytoplasmic expression of NLRP3 was detected in the epithelial reticular cells of the spleen and thymus, lymphocytes in the inguinal lymph nodes, cardiac muscle cells, cerebral cortex neurons, alveolar macrophages, renal tubule cells and liver sinusoidal endothelial cells. The results of this study will assist investigators in interpreting site-specific functions and roles of NLRP3 in inflammatory responses.

<p><b>OBJECTIVE</b>To explore the clinical effects of delayed open reduction and locking compressing plate (LCP) plus bone-grafting in medullary cavity for the distal comminuted fractures of tibia.</p><p><b>METHODS</b>Twenty-nine patients with the distal comminuted fractures of tibia were treated between March 2006 and September 2008, including 19 males and 10 females, ranging in age from 27 to 58 years with an average of 42.5 years. From wounded to hospital, the time was from 2 to 4 hours. According to AO classification, type 43-A1 were in 3 cases, type A5 in 12 cases, type A3 in 9 cases and type 43-C1 in 5 cases. Among them, there were 11 cases with open fracture (type Gustilo I in 5 cases, type Gustilo II in 6 cases) and 18 cases with closed fracture. Calcaneal traction was done in earlier stage (plaster external fixation in 5 cases), keeping the nagative liquid balance and electrolyte balance and improving the microcirculation. After the swolen limbs relieved markedly in 8 to 12 days,operating was done by open reduction and LCP internal fixation plus bone-grafting with own ilium in medullary cavity. Functional exercise was undergone in earlier stage and the wounded limbs loading weight on 10 to12 weeks after operation when the X-ray revealed the callus formed markedly.</p><p><b>RESULTS</b>The incision healed well without severe complication. All patients were followed up for from 6 to 14 months with an average of 12 months. All cases obtained bone union. According to the Mazur's evaluation standard, the results were excellent in 25 cases, good in 3 cases, and fair in 1 case.</p><p><b>CONCLUSION</b>The above treatment can reduce the damage of periosteum and medullary cavity, shorten the time of bone healing and decrease the rate of bone nounion markedly. The internal fixation was reliable and less complacation after surgery, but it is very important for the right preoperation assessment to soft tissue injuries and the good operation timing choice.</p>
