As the products of modern science,the effects of video games on children and adolescents drew the attention of psychologists.Anderson and Bushman proposed the General Aggressive Model,which could explain both the development of aggressive behavior and the difference of individual vulnerability to the effects of violent video games,and they advocated the effects,including short-term effects and long-term effects.Many researches about the relation of violent video games and aggression reported five consistent results:exposure to violent video games increased aggressive behavior,cognition,affect and physiological arousal,and decreased helping behavior.The positive intervention of parents can decrease negative effects of video games.

The technique of nipple-areola complex (NAC)-sparing mastectomy (NSM) facilitates the breast reconstruction due to preserving the skin and NAC of breast in the treatment of breast cancer. Key issues still remain controversial in NSM, in terms of the role of radiotherapy combined with NSM and sequence of radiotherapy and NSM, which arise from the consideration of the oncology safety. Some investigations addressed that post-NSM external beam irradiation and intra-operative radiotherapy (IORT) combined with NSM could reduce the local recurrence rate. Based on the appropriate patient selection and good quality of surgery, radiotherapy would be applied in different strategies of combination with NSM according to the risk of local recurrence of the cancer.

OBJECTIVE:To facilitate Chinese pharmaceutical industry's understanding and application of the new "Patent Law".METHODS:The amendment of the "Patent Law" related to 3 aspects of medicine,i.e.specifying regulations on the information disclosure in the utilization of genetic resources,adding the clause of forced permission for the patent drugs for the purpose of public health,and introducing the Bolar exception clause was analyzed using law hermeneutic.RESULTS & CONCLUSIONS:The medicine-related amendment of the new "Patent Law" generally reflects an international tendency of restricting pharmaceutical patents so as to maintain public interests,which is in line with the status quo of low technological level of pharmaceutical industry in China.

Objective To know the influence factors of untimely inoculation of measles vaccine among children of Enping, so as to provide scientific evidence for infectious diseases control. Method Cluster sampling was used and children from 2 towns of Enping were surveyed for their status of measles immunization and other information related to the immunization. Results The results indicated that the coverage rate of measles vaccine (MV) was 92.03%, and the untimely coverage rate was 36.20%. There were no statistical difference between local children and migrant children , urban children and rural children , as well as male children and female children. The results of multi-variate Logistic analysis suggested that the main factors that could decrease the untimely coverage rate of MV were inoculation appointment (OR = 0.415), vaccination health education (OR=0.385), guardians′ education (OR = 0.393) and guardians′ EPI knowledge (OR=0.472). The main factors that could increase the untimely coverage rate of MV were children′s suffering from diseases (OR=2.376) and egg allergy (OR=2.476). Conclusion Greater attention should be paid on measles immunization among children of Enping, which should be noticed and dealt with by proper authorities.

Liu Tea (Sibiraea angustata) at doses of 8.5 and 15.0g/kg ig coild redice TG, ?-LP, TC and elevate HDL-C levels of normal of normal or hyperlipoidemia rat. In vitro experiments indcated that S.angustata may promote the eatabolism of FFA. The contents of FFA in rat serum showed significant elevation in S. angustata treated groups as compared with the control. In addition, fat cells were smaller in S. angustat treated rats and mucoid changes could be seen under microscope. These results suggested that S. angustat could iegulate the metabolism of lipoid.

Objective To investigate the effect of hydroxyl starch (HES 200/0 5) infusion on blood rheology during operation Methods Forty adult ASA Ⅰ Ⅱ patients (male 28, female 12) scheduled for elective operation on spine (26 patients) and lower extremities (14 patients) were enrolled in this study The age ranged from 18 56 yr and weight from 40 85kg Preoperative heart, lung, liver and kidney function tests, blood routine exam, bleeding and coagulation time were all normal No patients had any history of abnormal bleeding The patients were randomly divided into two equal groups: control group(C) receiving lactated Ringer solution 1 000ml during operation and HES group receiving 6% HES 1 000ml No patient received any plasma or whole blood during operation The patients were premedicated with intramuscular atropine 0 5mg and sodium luminal 0 1g The operations were all performed under continuous epidural block (1 6% lidocaine with adrenaline 1:200 000) BP,ECG,and SpO 2 were continuously monitored during operation Blood pressure was maintained with range and SpO 2 above 97% Venuos blood samples were taken before anesthesia , 30min and 4h after the fluid had been infused and 24h after operation for determination of blood viscosity, plasma viscosity, hematocrit(HCT) index of red blood cell (RBC) aggregation and deformation and index of fibrinogen Results Blood viscosity, Hct, index of RBC aggregation and fibrinogen decreased significantly (P

Sentinel lymph node biopsy has been the standard axillary intervention for breast cancer patients with clinical negative axillary lymph nodes.Complete axillary dissection could be omitted for patients with negative sentinel lymph nodes.While, the optimal axillary intervention for patients with 1-2 positive sentinel lymph nodes remained controversial.This review introduced the latest research results of the axillary management for early stage breast cancer patients with 1-2 positive sentinel lymph nodes.

Bone remains the predominant site of metastasis in advanced breast cancer. Bone metastases dramatically decrease the quality of life. Moreover, pathologic fractures and other skeletal-related events (SREs) caused by bone metastases could result in higher mortality risk in patients with breast cancer. Palliative radiotherapy is a crucial element in bone metastases treatment. The present review discusses the emerging evidence in bone metastases of breast cancer, focusing on optimized radiotherapy strategies and multidisciplinary management.

OBJECTIVE To investigate the clinical manifestation and the reasons of misdiagnosis of allergic rhinitis patients with postnasal drip. METHODS The clinical data of 3 patients with allergic rhinitis who had the symptom of postnasal dr ip and were mi sdiagnosed were s tudied. RESULTS The three patients to be misdiagnosed as chronic sinusitis treated by antibiotics drugs, post cold cough syndrome without any treatment, and chronic rhinitis treated with partial inferior turbinectomy. The 3 patients were diagnosed allergic rhinitis and cured with budesonide nasal spray. CONCLUSION The reasons of misdiagnosis are listed as follows. 1. The clinic doctors don't listen to the patient's complaint comprehensively and get incorrect information. 2. The symptoms of allergic rhinitis are not typical. 3. Postnasal drip is the main complaint and cause irritable cough, pharyngeal itching, globus. 4. The symptoms of allergic rhinitis are covered by other simultaneous diseases.

Objective To study the prevention of gentamicin ototoxicity by resveratrol(Res) in guinea pigs.Methods Auditory brainstem response and cochlear preparation transmission electron microscope were used to evaluate the effects of hair cell on hearing threshold and morphology of hair cell. Serum levels of GM were also tested. It was comprised of five groups,each group had eight animals.GM and Res were tested alone and in combination,besides control group.Results GM group developed a progressive threshold shift. Injury in high frequency was significantly more severe than that in low frequency (P
