Objective:To observe the efficacy of Yuebi Jia Banxiatang on old patients with community acquired pneumonia （CAP） combined with syndrome of phlegm heat damming lung， and observe effect on inflammatory markers and prognosis. Method:A total of 120 patients with CAP were randomly divided into control group （60 cases） and observation group （60 cases） by random number table. In control group， 55 patients finished the therapy （3 patients fell off or were lost to follow-up， 2 were eliminated）， 55 patients in observation group completed the therapy （5 patients fell off or were lost to follow-up）. Both groups' patients got anti-infection and other comprehensive therapies. Patients in control group got Feilike mixture， 20 mL/time， 3 times/day. Patients in observation group obtained Yuebi Jia Banxiatang， 1 dose/day. The course of treatment for the two groups continued for 10 days. Antipyretic time and antipyretic rate at the 5th day after treatment， relief time of cough， expectoration and lung rale were recorded. And clinical pulmonary infection score （CPSI）， time （CPSI<6） and time to stop antibiotics were recorded. Before and after treatment， syndrome of phlegm heat damming lung was scored， and failure of initial treatment was also recorded. Levels of procalcitonin （PCT）， red blood cell volume distribution wid （RDW）， D-dimer （D-D） and synpeptin， high sensitivity C-reactive protein （hs-CRP）， tumor necrosis factor-α （TNF-α）， interleukin （IL-1β） and IL-6 were measured. Recurrence rate of chest radiograph was recorded， and safety was evaluated. Result:Relief time of antipyretic， cough， expectoration and lung rale in observation group were less than those in control group （P<0.01）. Antipyretic rate at the 5th day after treatment， antibiotic discontinuation rate， recurrence rate of chest radiograph were 85.45% （47/55）， 94.55% （52/55） and 90.91% （50/55）， which were higher than 65.45% （36/55）， 81.82% （45/55） and 74.55% （45/55） in control group. And initial treatment failure rate was 5.54% （3/55）， which was lower than 20.00% （11/55） in control group （P<0.05）. Scores of CPSI and syndrome of phlegm heat damming lung were less than those in control group （P<0.01）. And levels of PCT， RDW， D-D， peptide， hs-CRP， TNF-α， IL-1β and IL-6 were all below the level in control group （P<0.01）. Total effective rate of traditional Chinese medicine （TCM） syndrome was 96.36% （53/55）， which was higher than 83.64% （46/55） in control group （χ2=4.949， P<0.05）. And there was no adverse reactions relating to traditional Chinese medicine. Conclusion:In addition to anti-infection and other comprehensive therapies， Yuebi Jia Banxiatang can control the clinical symptoms， reduce the degree of pulmonary infection and disease， control the inflammatory reaction， shorten the course of disease and improve the prognosis， with a significant effect and safety in clinical use.

Objective To investigate the role of SDF-1/CXCR4 axis on the apoptosis of human degenerative nucleus pulposus cells (NPCs) and its potential molecular mechanism .Methods The intervertebral disces tissues from clinical discectomy were divided into normal group and intervertebral disc degeneration ( IVD) group according to Pfirrmann classification.The different expression of SDF 1 and CXCR4 in human IVDs was tested by immunohistochemistry, quantify polymerase chain reaction (q-PCR) and Western blot.The primary degenerative NPCs were primary cultured.The generation Ⅲ~Ⅴ NPCs was treated with 10 ng/mL SDF-1, in the presence of or in the absence of CXCR4 siRNA transfection and 20 μmol/L NF-κB inhibitor (pyrrolidine dithiocar bamate,PDTC).The transfection efficiency and target protein of signal pathway were verified by Western blot , the apoptosis of NPCs were tested by Annexin V /PI, the nucleus transferlocation of P65 from NF-κB were tested by immunofluorescent method.Results SDF-1and CXCR4 were both expressed in all donor tissues, however, there was a significantly increased in the degenerative IVDs .The apoptosis of degenerative NPCs was expedited by SDF -1 stimulation,which was significantly suppressed by CXCR 4 silencing by siRNA (P<0.05).Furthermore, with SDF-1 stimulation,the expressions of phosphorylated P 65 was significantly increased and the P65 perssad transferred to the nucleuses,which could be suppressed by the NF-κB inhibitor, PDTC(P<0.05).Conclusions The expression levels of SDF-1 and CXCR4 are increased in degenerative NP tissue.The SDF-1/CXCR4 axis is considered to induce apoptotic of human degenerative NPCs via the NF-κB signaling pathway.

Obesity is a risk factor for allergic rhinitis in children of Wuhan (China)

BACKGROUND: The relationship between obesity and allergic diseases in children of China is unclear. OBJECTIVE: To analysis the relationship between obesity and overweight and the prevalence of allergic diseases and the impact of gender. METHODS: Questionnaire based on those used in National Study of Asthma and Allergies in Childhood in China. The study included 3,327 participants (23.7% aged 2–6 years, 65.8% aged 7–12 years, 10.5% aged 13–14 years) in Wuhan City. Allergic diseases were determined by physicians. RESULTS: Overweight was found in 35.68% of participants (8.96% of 2–6 years old, 32.83% of 7–12 years old, and 48.57% of 13–14 years old), obesity in 12.53% (4.18%, 12.01%, and 4.29%, respectively). Obesity (odds ratio [OR], 1.33) increased the prevalence of allergic rhinitis and atopic dermatitis. Obesity (OR, 1.48) affected the incidence of allergic rhinitis in girls. There was no relationship between body mass index (BMI) and asthma in child from Wuhan City. Obesity and overweight did not affect the frequency of asthma, food allergy, and drug allergy. CONCLUSION: Obesity increased the prevalence of allergic rhinitis and atopic dermatitis in child. Higher BMI was no relationship with the prevalence of asthma, food allergy, and drug allergy.

Research on non-contacting ECG measurement and filtering method / 生物医学工程学杂志

Non-contact measurement is an effective method of long time measurement of human electrocardiograph (ECG) signal. Because the relative position between measuring electrode and human body is not fixed, this method could result in constant changes of ECG signal collection. It often appears ECG signal distorting and weakened in filtering. This paper, using the principal component analysis (PCA) basic theory, proposes a fast adaptive PCA denoising algorithm which can automatically adjust the parameters according to the changes of ECG signal. The experiment proved that PCA denoising could be barely impacted by signal changes and can disposably remove interference signal on the premise of keeping the main features of ECG signal and can prevent ECG signal from being weakened in filtering at the same time.

Age and gender difference of clinical and non-clinical depressive symptoms in children / 临床儿科杂志

Objectives To study the age and gender distribution of clinical and non-clinical depressive symptoms in chil-dren, and the potential link between non-clinical and clinical depressive symptoms. Methods 4520 children aged 8-15 years old were screened for mental disorders by Strength and Dififculties Questionnaire (SDQ) and the Development and Well Being Assessment (DAWBA), and further assessed by the Depression Self-Rating Scale for Children (DSSC). Fifty-three children diagnosed as depressive disorder were included in clinical group and 1504 children without depression disorders whose DSSC scores≥14 were included in non-clinical group. The relationship between gender, age and DSSC scores was analyzed. Results Interaction effect on DSSC scores between gender and age was found in clinical group (F=4.40, P=0.049), but not found in non-clinical group (F=1.04, P=0.409). DSSC scores of girls were higher than that of boys in clinical group (t=2.16, P=0.048). There was no statistically signiifcant main effect of gender in non-clinical group (F=0.21, P=0.646). No signiifcant difference in DSSC scores existed among different age groups in clinical group (F=0.82, P=0.573). There was signiifcant main effect of age in non-clinical group (F=1.96, P=0.048). Conclusions There were different age and gender distribution of clinical and non-clinical depressive symptoms in children.

Relationship between domestic child abuse and mental health in children aged 10-13 / 中华行为医学与脑科学杂志

Objective To investigate domestic child abuse within one year before the survey being conducted in Grades 4-6 preliminary school students and explore the relationship between domestic child abuse and mental health problems including prevalence of mental disorders,anxiety,depression as well as children's selfawareness in this sample.Methods Screen Questionnaire of Child Abuse was used to screen all the students participated in the survey.For those students whose screen results were positive,further face to face interview was needed to verify the abuse history.Once a child was identified as abused one,a student without abuse history would be matched by sex and the same age.Both groups with abused history and without abuse history over past year were evaluated by the two child psychiatrists with diagnostic an statistical manual of mental disorder (DSM-Ⅳ) and mental health scales.Results 1500 10-13 year-old children received child abuse screening.23.73％ students surveyed over the past year suffered child abuse in the family.The proportion of boys who were victims of domestic child abuse was 30.44％ while 17.44％ to girls (x2 =5.95,P ＜ 0.01).The proportion of male students who were victims of domestic abuse was two times that of female students.For all participants,14.6％ had been suffered one-way abuse,5％ for two-way abuse,and 3％ for three-way abuse.Prevalence of anxiety disorder in abused students was higher than in non-abused ones (9.26％ vs 3.45％,x2 =3.19,P=0.0015).Similarly,the rate of disruptive behavior disorder in abused students was higher than in non-abused ones(18.53％vs 9.22％ x2 =3.61,P=0.0001).The total scores of The Screen for Child Anxiety Related Emotional Disorder was higher in abused students group than in non-abused students group while the total scores of Piers-Harris Children's self-concept Scale was lower in abused student group than in non-abused student group.Conclusion Domestic child abuse in 10-13 old-age students is a widespread phenomenon and abuse history over last year is associated with current mental health level.
