The obese children are increasing at a surprisingly high annual rate of 9.1 percent in China.Meanwhile children are lack of health consciousness and self-protection,thus obese children are more vulnerable towards obesity.Since parents are responsible for their children's daily lives and behaviors,the health education of obesity should be started with those parents with obese children.This paper calls to carry out health education aimed at parents of obese children through multiple means such as community health services,taking advantage of public media and establishing specific clubs,in order to effectively control the increase of obese children.

SUMMARY Delayed postoperative spinal epidural hematoma(DPSEH) is a rare and potentially devastating complication of laminoplasty, and cervical nerve root palsy occurs more frequently than DPSEH, especially with C5 nerve root palsy. The authors describe a case of DPSEH with C5 nerve root palsy that developed in a patient 3 days after he underwent laminoplasty. In this case, a 78-year-old man with a history that having taken Aspirin without the doctor’s instruction for 5-6 years,he underwent cervical laminoplasty for mild myelopathy. On the 3rd postoperative day, he complained of weakness of his left upper extremity and could not raise his left arm. The symptom aggravated in the next few days. On the 9th postoperative day, there was an obvious motor deficit of both upper and lower extremities. Magnetic resonance imaging demonstrated abnormal signal characteristics consistent with a hematoma at levels C3-C4, compressing spinal cord. The clot was evacuated during emergency revision surgery, and the postoperative course after the operation was uneventful and the muscle strength was improved five days later. Therefore, the symptoms of DPSEH are not so typical that its possibility should be kept in mind. Sometimes a differential diagnosis should be made with C5 nerve root palsy which may only represent weakness of upper extremities. The authors recommend that magnetic resonance imaging is helpful for the diagnosis of DPSEH and a revision surgery should be taken as soon as possible once the hematoma causing the neurologic deterioration was confirmed.

OBJECTIVETo record the electrical activities of Antirior cingulate cortex (ACC) neurons by in vivo multi-channel recording methods using the model of complete freund's adjuvant (CFA) induced conditioned place avoidance (C-CPA), which has been set up in our previous studies.

METHODSThe electrode was self-made and the CPA responses were recorded by in vivo multi-channel recording method.

RESULTS(1) The electrical activities of ACC neurons could be successfully recorded by the self-made electrode. (2) Before or after the injection of CFA, rats were respectively conditioned to the different place. The firing rates of ACC neurons in the CFA-paired place vs that in the non-CFA-paired place was (0.853 ± 1.377) imp/s vs (0.221 ± 0.971) imp/s (P < 0.05, n = 26). (3) The CPA responses in the CFA-paired place vs that in the non-CFA-paired place were (303.55 ± 61.77)s vs (140.32 ± 33.52)s(P < 0.05, n = 6).

CONCLUSIONThe firing rates of rACC (rostral Anterior Cingulate Cortex) neurons were involved in the occurrence of the affective pain.

Ashi point (tonsil) in combination of the pricking and bleeding technique on Shaoshang (LU 11 )and Shangyang (LI 1) were used to treat 58 outpatients of acute tonsillitis. The results showed cure in 38 cases,remarkable effect in 17 cases and failure in 3 cases by one treatment, and the total effective rate in 95%.

OBJECTIVE To find the cause of lower respiratory tract infection as soon as possible and take measures to control the infection.METHODS The records of hospitalized patients in the intensive care unit(ICU) form Nov 28 to Dec 6 in 2006 were analyzed;and the disinfection efficiency,sterilization effect and the environment were monitored.RESULTS The incidence rate of lower respiratory tract infection was 54.55%.The qualified rate of disinfection and sterilization monitoring was 35.71%.The respiratory tubing,bed handle,bottle openner,computer mouse,the surface of the file cabinet and air vents were heavily infected.The Staphylococcus aureus was isolated from the quilt cover and the surface of the file cabinet.CONCLUSIONS We should put more emphasis on the management of the infective disease in the ICU,on hand washing and the cleanliness and maintenance of the devices.Disinfection and isolation guidelines should be strictly followed to reduce the incident rate of infection in the ICU.

Objective To investigate the effects of advanced glycation end products(AGEs) on expression of peroxisome proliferator-activated receptor-?(PPAR?) mRNA in rat renal cortex.Methods Normal rats were given tail vein injection with either AGE-modified rat serum protein(AGEs)or AGE-RSP followed by intraperitoneal injection of AG(AGEs+AG)or native rat serum protein(native RSP).Normal rats without any treatment were as controls(Control).PPAR-? mRNA expression was analysed by reverse transcriptase-polymerase chain reaction(RT-PCR).Results PPAR-? mRNA expressed in all rat kidney cortex.There was a decrease for PPAR-? in mRNA levels in the renal cortex of AGEs-treated rats(P

Objective To explore the effect of boiled fenugreek seeds on renal matrix metalloproteinase-2(MMP-2) activity in diabetic rats.Methods The model of diabetes was built with STZ in rats.The model rats were randomly divided into diabetes control groups (DM ) (n=10) and fenugreek seeds groups(FN) (n=10,and while normal control group (N) (n=10)rats was used.Diabetic rats were treated with fenugreek seeds for 12 weeks,the renal morphology and MMP-2 activity were observed in three groups .Results After diabetic rats were treated with fenugreek seeds for 12 weeks,optical microscopic examination indicated that the glomerular structure in N group was normal,the glomerular lesions in rats of DM groups were seriously and the pathologic changes of glomerular in rats of FN groups were alleviated significantly.Immunohistochemical results showed that the Col Ⅳ expression in glomerular ECM was increased in DM group compared with N group,and was decreased in FN group.The activity of MMP-2 was increased in FN group (1.41?0.18) compared with DM group (1.05?0.19) (P

Objective To investigate the effect of oxcarbazepine(OXC) and sodium valproate(VPA) on electroencephalogram(EEG) and peripheral blood levels of homocysteine(Hcy) and asymmetric dimethylarginine(ADMA) in adult patients with partial epilepsy.Methods From May.2014 to May.2015,a total of 100 patients with partial epilepsy were enrolled and randomly divided into treatment group(treated with OXC) and control group(treated with VPA),with 50 cases in each group.After treatment,changes of EEG indices,Hcy,ADMA,cognitive function and adverse reaction were analyzed.Results Before treatment,there was no significant difference of EEG indices between the two groups(P>0.05).After treatment,the incidence rates of α wave decreasing more than 0.5 Hz,increasing of θ wave and increasing of δ wave were significantly different(P< 0.05).Before treatment,there was no significant difference of serum Hcy and ADMA levels between the two groups(P>0.05).After treatment,serum Hcy and ADMA levels were both significantly increased(P<0.05).Before treatment,Mini-mental State Examination(MMSE) scores of the two groups were without significant difference(P>0.05).After treatment,MMSE score of treatment group was higher than that of control group(P<0.05).In treatment group,there were 1 case of skin rash and 2 cases of gastrointestinal discomfort,which were self-improved.In control group,there were 3 cases of dizziness,5 cases of skin rash and 1 case of gastrointestinal discomfort,which were self-improved.Conclusion The effects of OXC and VAP on peripheral blood levels of Hcy and ADMA could be similar,and compared with VAP,OXC could significantly improve cognitive function in patients with epilepsy.
