Attention deficit hyperactivity disorder is a common neurodevelopmental disorder characterized by persistent attention deficit, hyperactivity, and impulsive behaviors that are not consistent with developmental age.Academic and vocational difficulties, social exclusion, and delinquent behaviors are manifested in daily life.It is also commonly accompanied by psychiatric problems.At the same time, mental problems are common, and the overall quality of life is greatly affected, placing a heavy burden on society as well as the family.International attention deficit hyperactivity disorder experts have developed a common and comprehensive International Classification of Functioning, Disability and Health core set of classifications for assessing individual functioning in attention deficit hyperactivity disorder.

Objective:To analyze the epidemiological characteristics of Mycoplasma pneumoniae (MP) infection and its genotyping in children with community-acquired pneumonia (CAP), as well as macrolide resistance and gene mutation genotyping, in order to provide evidence for the prevention and treatment of Mycoplasma pneumoniae pneumonia (MPP) in children.Methods:MP positive cases in 620 hospitalized children at Maternal and Child Health Hospital of Sanshui District, Foshan City with CAP were detected.P1-RFLP genotyping was performed for the MP positive cases.The distribution of the MP positive, type Ⅰ and type Ⅱ in different years and different genders, ages as well as seasons were analyzed.The mutations of macrolide resistance genes in MP were detected.The differences of A2063G and A2064G mutations of the drug-resistant mutant gene in each year, gender, age and season were analyzed.Results:Among 620 children with CAP, 198 were MP positive, and the infection rate was 31.94%.There was little difference among the years.The infection rate was higher in female than that in male.The infection rate gradually increased with the increase of age, and the highest infection rates were found in pre-school age and school age.The infection rates in summer and autumn were significantly higher than those in spring and winter.Among 198 children, P1-RFLP classification showed that 157 (79.29%) cases were P1-Ⅰ and 41 (20.71%) cases were P1-Ⅱ.There was no significant difference in the distribution of type Ⅰ and type Ⅱ in each year, gender, age as well as season.A total of 143 cases were tested for mutation of macrolide resistance gene, in 125 of them, MP gene mutation resulted in drug resistance, and the overall drug resistance rate was 87.41%.MP gene mutation led to drug resistance in 125 children, 66 (52.80%) cases had A2063G mutation and 53 (42.40%) cases had A2064G mutation.There was no significant difference between two types in each year, gender, age and season.Conclusion:MP infection rate of CAP among children in our hospital is 31.94%, and is more common in femal, and the infection rates are highest in pre-school age and school age, with summer and autumn as the season of high incidence.The P1-RFLP typing showes no significant differences among the years, genders, ages and seasons.The drug resistance gene mutation among children is high.Time, gender, age and season does not affect drug resistance gene mutation.

Objective:To explore the changes of bone turnover markers and geometric parameters of hip bone in overweight postmenopausal women with metabolic syndrome(MS), as well as the influence of MS components. To analyze the association of these factors with the risk of fracture.Methods:A total of 505 overweight postmenopausal female patients who underwent health check-up in Lianhu Community Service Center, Danyang City, Jiangsu Province from January to December 2017 were selected. According to the MS diagnostic criteria of the International Diabetes Federation(2009), the patients were divided into MS group( n=331)and non-MS group( n=174). Blood samples were collected to determine the level of procollagen type 1 N-terminal propeptide(P1NP)and carboxy-terminal cross-linked telopeptide of type 1 collagen(CTX). Bone mineral density and hip bone geometry parameters were tested with dual-energy X-ray absorptiometry and hip structural analysis software. Results:The incidence of osteoporotic fracture and hip fracture in MS group was significantly higher than that in non-MS group(21.1% vs 13.8%, 4.8% vs 1. 1%, P<0.05). However, the bone mineral density of lumbar vertebra 1-4, femoral neck, and total hip in MS group was significantly higher than that in non-MS group, which remained after adjusting for age( P<0.05), but the difference disappeared after further adjustment for body mass index( P>0.05). The P1NP, CTX, femur strength index(FSI), section modulus(SM), and cross-sectional area(CSA)of MS group were significantly lower than those of non-MS group, the buckling ration(BR)was significantly higher than that in non-MS group, and the differences were still statistically significant after adjusting for age and body mass index( P<0.05). There was no significant difference in bone mineral density of lumbar vertebra 1-4, femoral neck, total hip, P1NP, and CTX between fracture group and non-fracture group in patients with MS. But FSI, SM, cross-sectional moment of inertia(CSMI), and CSA were significantly lower, BR was significantly higher( P<0.05) and femur strength decreased in patients with fracture. Regression analysis showed that high BR was an independent risk factor for fracture risk, while high FSI, SM, CSMI, and CSA were protective factors. Multivariate linear regression analysis showed that wasit circumference, diastolic blood pressure, and fasting plasma glucose were the main MS components affecting bone mineral density, bone turnover indexes, and hip bone geometry parameters. Conclusions:Overweight postmenopausal MS patients had decreased bone turnover rate, femoral strength, and relatively poor bone quality. Hip bone geometry parameters can be used as one of the methods to assess fracture risk in MS patients. Waist circumference, diastolic blood pressure, and fasting blood glucose are the important MS components affecting bone mass and bone quality.

Objective:To explore the risk of hip fracture, changes of composite indices of femoral neck strength and its influential factors in non-low-weight postmenopausal women with type 2 diabetes mellitus(T2DM).Methods:A total of 626 non-low-weight postmenopausal women were selected and divided into type 2 diabetes group, pre-diabetic group, and non-diabetic group according to the diagnostic criteria of the American Diabetes Association in 2010. Each participant completed the questionnaire, physical examination, laboratory examination, and Dual-energy X-ray absorptiometry(DXA) examination.Results:Hip fracture rate in T2DM group was significantly higher than that in non-diabetic group(3.4% vs 0.7%, P<0.05), while no significant difference was observed between pre-diabetic group and non-diabetic group(1.1% vs 0.7%, P>0.05). Bone mineral density(BMD) of lumbar spine 1-4, femoral neck, and total hip was comparable between T2DM group and non-diabetic group or pre-diabetic group and non-diabetic group, respectively( P>0.05). The composite indices of femoral neck strength in T2DM group was significantly lower than that in non-diabetic group( P<0.05), but there was no significant difference between pre-diabetic group and non-diabetic group( P>0.05). Regression analysis showed that age and body mass index were the main influential factors of the femoral neck bone mineral density and the composite indices of femoral neck strength( P<0.05). Conclusion:The composite indices of femoral neck strength could be used as one of the markers to evaluate the risk of hip fracture in type 2 diabetic patients.

Objective:To investigate the types of non-tumor diseases in patients with cancer, and to explore the effects of those dis-eases on the diagnosis and treatment of cancer patients. Methods:We collected the medical records of cancer patients from January 2013 to December 2017 in Peking University Cancer Hospital, and screened for non-tumor diseases. The clinical records of the patients in this group were analyzed retrospectively, and the effects of those diseases on the diagnosis and treatment of tumors were dis-cussed. Results:Of the 1,323 cases of inter-hospital consultation, 1,153 cases of non-tumor disease (87.2％) were selected. There were 773 men (67.0％) and 380 women (33.0％) included. The median age was 62 (14-90) years. The primary tumor types included lung can-cer, gastric cancer, lymphoma, colorectal cancer, esophageal cancer, breast cancer, malignant melanoma, liver cancer, cholangiocarci-noma/gallbladder cancer, pancreatic cancer, and other tumors. Non-neoplastic diseases included cardiovascular disease in 356 cases (30.9％), respiratory system disease (17.0％) in 196 cases, digestive system disease in 107 cases (9.3％), skin and venereal diseases in 81 cases (7.0％), nervous system lesions (6.4％) in 74 cases, urinary system disease in 72 cases (6.2％), blood disease in 70 cases (6.1％), en-docrine and metabolic diseases in 47 cases (4.1％), autoimmune disease in 23 cases (2.0％), and other diseases (11.0％) in 127 cases. Impact on tumor diagnosis and treatment was as follows:direct, 771 cases (66.9％);no influence, 313 cases (27.1％);and uncertain, 69 cases (6.0％). Conclusions:Cardiovascular disease is a major non-tumor disease associated with cancer. Non-neoplastic diseases are important factors affecting the diagnosis and treatment plans of cancer.

Background and objective Radiotherapy combined with chemotherapy or molecular targeted therapy remains the standard of treatment for brain metastases from non-small cell lung cancer (NSCLC). hTe aim of this study is to determine if the deferral of brain radiotherapy impacts patient outcomes.Methods Between May 2003 and December 2015, a total of 198 patients with brain metastases from NSCLC who received both brain radiotherapy and systemic therapy (chemo-therapy or targeted therapy) were identiifed. hTe rate of grade 3-4 adverse reactions related to chemotherapy and radiotherapy had no signiifcant difference between two groups. 127 patients received concurrent brain radiotherapy and systemic therapy, and 71 patients received deferred brain radiotherapy after at least two cycles of chemotherapy or targeted therapy. Disease speciifc-graded prognostic assessment was similar in early radiotherapy group and deferred radiotherapy group.Results Me-dian overall survival (OS) was longer in early radiotherapy group compared to deferred radiotherapy group (17.9 monthsvs 12.6 months;P=0.038). Progression free survival (PFS) was also improved in patients receiving early radiotherapy compared to those receiving deferred radiotherapy (4.0 monthsvs 3.0 months;P<0.01). Receiving tyrosine kinase inhibitor (TKI) therapy atfer the diagnosis of brain metastases as any line therapy improved the OS (20.0 monthsvs 10.7 months;P<0.01), whereas receiving TKI as ifrst line therapy did not (17.9 monthsvs 15.2 months;P=0.289).Conclusion Our study suggests that the use of deferred brain radiotherapy may resulted in inferior OS in patients with NSCLC who develop brain metastases. A prospec-tive multi-central randomized study is imminently needed.

Pulmonary asthenia is one of the chronic consumptive lung diseases because of the weakness of pulmonary lobe. It would be the outcome of many chronic lung diseases with poor prognosis. In recent years, preventing and treating pulmonary asthenia by traditional Chinese medicine (TCM) has been one of the research focuses and some fruits have been received. This paper summarized pulmonary asthenia from the aspects of etiology and pathogenesis, syndrome differentiation, TCM treatment so as to provide theoretical basis and proofs for treatment of pulmonary asthenia by TCM.
