Epilepsy is one of the most common diseases in children.The diagnosis,classification and treatment of epilepsy are improving gradually and meet with the international standards.However,the understanding of the clinical significance of epilepsy combined with the mental and behavioral problems is not sufficient,which leads to the backlogging of the diagnosis and intervention of the co-morbidity,and further affects the long-term prognosis.The prevalence of epilepsy co-morbid with attention deficit hyperactivity disorder (ADHD) is high,which seriously affects the quality of the lives in children and their families.Timely diagnosis and standardized treatment is very important for the clinical workers to improve the long-term prognosis of these children.In this paper,the possible mechanism,the disease characteristics,the standardized diagnosis and treatment of epilepsy combined with ADHD,are briefly introduced.

Objective:To improve previous method of primary rat cortical neuron culture to get purer and more long-lasting cells for study.Methods:Timed-pregnant Wistar rats at a gestational age of 16 or 17 days(16-17 d) were used.Fetal brains were removed and the cerebral cortices were dissected out.Papain digestion and mechanical dissociation were combined to conduct mono-cell suspending media.Four to six hours(4-6 h) post-plating,all plating media were removed from cultures and replaced with Neurobasal medium supplemented with B27.On the third day,10 ?mol/L cytosine arabinoside(Ara-C) was added to the culture for 24 h to inhibit the outgrowth of glial cells.Half of the culture medium was changed every week.The morphological changes of neuron cells were observed by light microscope.Double immuno-staining of microtubule-associated protein 2(MAP2) and karyon were applied to assess the culture purity.Evaluation of synapse formation was processed by immunocytochemical analysis using antibodies against both pre-and postsynaptic protein markers.Results:The improved method could remarkably increase the cell number and reduce neuronal damnification.The primary culture was characte-rized by high uniformity,purity,normal synapse formation and longtime livability.Conclusion:This is a simple and reliable technique for the in vitro primary culture of rat cortical neurons.

Objective To study the clinical application of the complete audiologic evaluation battery consisting of ABR,ASSR and behavioral audiometry in sound field for the identification of sensorineural losses in children.Methods In the study 48 children were divided as group PTA of the children assessed by pure tone audiometry and ABR and ASSR test,and group BA of the children unable to perform on behavioral evaluations.Results The analysis of the audiometric results of group PTA showed significant correlation between the ASSR thresholds and pure tone thresholds(P＜0.01) at various frequencies.The correlation coefficients were 0.75,0.76,0.76,and 0.83 at different frequencies.The ASSR-PTA linear regression was utilized.The comparison of the ABR and ASSR results of group BA indicated that 23 ears responded in ASSR but without responses in ABR.Those without ASSR responses also had no ABR There were 116 tests in total four frequencies for the 29 ears.83 responses were obtained from ASSR,89 responses from behavior audiometry and 96 from the use of the both tests.Conclusion The comprehensive audiologic evaluation battery could be used to test younger children with severe heating loss children as compared to the pure tone audiometry alone.More detailed data can be obtained thus from children to assist in rehabilitation in a more effective mariner.

A questionnaire survey on chronic heart failure management was conducted in 110 physicians from Xindu,Supo,Jiajiang and Xinhua community hospital in Chengdu from January 2007 to June 2010.Results showed that 77.3％ (85/110) of community physicians lacked knowledge about prevention,diagnosis and treatment of chronic heart failure,and the diagnostic accuracy rate was only 51.3％ (40/78) in these community hospitals.There was lack of awareness of the guideline of chronic heart failure:the rate of β blockers use was 15.0％ (6/40) and only 5.0％ (2/40) used the target dose; the rate of angiotensin converting enzyme inhibitor use was 17.5％ (7/40) and only 7.50％ (3/40) used the target dose.In addition,90％ (99/110) of community doctors lacked the education and management for patients with heart failure.The survey suggests that the current situation of chronic heart failure management in community physicians in Chengdu is unsatisfactory.It is necessary to strengthen the training of community physicians.

AIM and METHOD: In terms of difference value between bleeding blood volume that caused hemorrhagic shouk (HS) and residual blood volume at 2 h after HS, showed that HS at 5.3 kPa level was compen- satory and at 4.0 kPa level was decompensatory. Comparing some blood changes between HS two levels and their changes while pretreated with captopril (Capt. ) to reduce the release of angiotensin Ⅱ (Ang-Ⅱ), so as to inveshgate the significance of Ang - Ⅱ during HS. RESULTS: The residual blood volume in 4.0 kPa HS + Capt. group are again from near "zero" value in simple 4.0 kPa HS group. In both two HS level groups found blood dilution and was not influenced by pretreating with Capt.; contents of K+ and aldosterone increased, but Na+ had no changes, in Capt. + HS group, the former two contents reduced and Na+ had no changes comparing with each HS group. In two HS groups, the bind lactate, lactic dehydrogenase (LDH), blood urea nitrogen (BUN) increased and had more increment in 4.0 kPa HS group. All these changes could be prevented by pretreating with Capt. The blood glucose in 5.3 kPa HS group increased markedly and Capt. had no influence on it, but decreased extremely in 4.0 kPa HS group and Capt. could make it re - increased. CONCLUSIONS: Artery blood pressure (ABP) at 5 .3 kPa level was compensatory HS and ABP at 4 .0 kPa level was decompensatory HS, some changes on decompensatory HS were more serious and severe than compensatory HS, Capt. has protective effects on some changes during HS and could prolong the survival time of decompensatory HS, all that indicated the increment of Aug - Ⅱ is an important pathogenetic factor during HS.

Objective To analyze the results of survival and local regional control of early-stage breast cancer patients treated with breast-conserving surgery and whole breast radiation therapy, and to explore the factors influencing local control. Methods From October 1995 to September 2005,335 patients with early-stage breast cancer were treated with breast conservative therapy, including 25 with post-operative radiotherapy alone( group A), 194 with sequential chemo-radiotherapy( group B) ,80 with concurrent chemoradiotherapy( group C), and 36 with chemo-radio-chemotherapy (group D). Axillary dissection was performed in 312 patients and sentinel node biopsy in 2. Adjuvant chemotherapy was given to 310 patients. Radiation of 50 Gy in 25 fractions was delivered to the whole breast in 256 patients,and to the breast and regional nodes in 79. Another 10 Gy in 5 fractions was boosted to the tumor bed. The proportion of patients with surgery-radiation interval of less than 4 weeks,4-8 weeks,8-20 weeks and over 20 weeks was 16.4%, 23.6% ,37.3% and 22.7% ,respectively. Concurrent chemo-radiation and" sandwich" modality were delivered in 80 and 36 patients,respectively. Results The median follow-up was 48(25.3-146.7) months. The 5-year local-regional control and ipsilateral breast control rates were 94.5% and 95.6%, respectively. The 5-year disease-free survival,metastasis-free survival and overall survival rates were 88.6% ,93.2% and 98.8% ,respectively. Lymph-vascular invasion and neural invasion were significant factors influencing local control in univariate analysis. No significant differences were found in local control rates among different surgery-radiation intervals or different sequencing of radiotherapy and chemotherapy. Multivariate analysis showed that lymph-vascular invasion and reexcision for positive or unknown margin were independent prognostic factors influencing local control. In group A + B, C and D, the frequency of grade Ⅲ skin toxicity was4.5%.80.0%.and 77.0%,respectively(χ2=226.00,P=0.000).Conclusiom Breast conservative therapy for early-stage breast eancer results in good local-regional control and overall survival.Lymph-vascular invasion and reexcision are independent prognostic factors for local control.Surgery-radiation interval and sequencing of radiotherapy and chemotherapy have no impact on local contr01.Grade Ⅲ skin toxicity of the concurTent radio.chemotherapy and the chemo.radio.chemotherapy group is significantly higher than that of the sequential chemotherapy-radiotherapy plus radiotherapy alone group.

Objective To compare the expression of nitric oxide synthase (NOS ) in patients with gastroesophageal reflex disease (GERD)and healthy controls.Methods The distribution and relative protein amount of two NOS subtypes (nNOS and iNOS)were determined with immunohistological method,and their mRNA levels were measured with real-time PCR method.Results The nNOS and iNOS were mostly distributed in the cytoplasm in epithelia of esophageal mucosa.The nNOS and iNOS in reflux esophagitis (RE)were significantly higher than in non-erosive reflux disease (NERD)patients and healthy controls (P <0.05 ).The mRNA levels of nNOS and iNOS were also significantly higher in RE patients than in NERD patients and healthy controls (P <0.05).Conclusion The expressions of nNOS and iNOS were increased in the esophagus of RE patients,which may be related to the effects of NO on the onset of GERD.

Objective To investigate the feasibility of quantitative measurement of fat concentration by CT spectral imaging in a mice model of fatty liver.Methods Twenty-four mice with different degrees of fatty liver underwent CT spectral imaging.CT values of liver parenchyma under mixed X-ray energy and 65 keV,fat concentration based on various basic material pairs (fat/water,fat/io-dine,fat/calcium)and spectral curves were obtained.Liver specimens were obtained to measure the concentration of triglyceride , and HE staining was performed.Correlations between various CT indexes and triglyceride concentration were analyzed.Results Correlation between fat concentration (fat/water pair)and triglyceride (r =0.91 5 )was better than that between CT values on 65 keV and triglyceride (r=-0.858),as well as polychromatic CT values (r=-0.81 6).All the P values were<0.001.Correlations between fat concentrations based on fat/iodine or fat/calcium pairs and triglyceride were relatively low (r=-0.726,-0.660).CT indexes on 1.25 mm slice thickness performed better than those on 2.5 mm.With fatty liver degree increased,the shape of spectral curve changed gradually.Conclusion Liver fat concentration can be measured by CT spectral imaging noninvasively,accurately and quantitatively in a mice model of fatty liver.

Objective To investigate the feasibility and clinical effect of cannulated screws plus separate vertical wirings technique for acute fracture of the inferior pole of the patella.Methods From May 2012 to September 2013,14 patients with fresh closed unilateral fracture of the inferior pole of the patella were treated with the cannulated screws plus separate vertical wirings.Eight patients were injured in traffic collisions and 6 in fall accidents.Fracture AO classification was type 34A1 in 8 patients and type 34A2 in 6 patients.Time from injury to operation was 1-7 days (mean,2.5 days).Number of tie wires was determined according to the degree of fracture comminution.Fracture healing,fixed position and patellar length were evaluated by radiographic examination postoperatively.Knee mobility and Bostman evaluation system were investigated to analyze the clinical effect.Results All the patients obtained average 15-month follow-up (range,12 to 29 months).At postoperative 2 months,the fracture healed with good alignment of the broken bone and proper place of the internal fixation device noted on the X-ray films.At postoperative 6 and 12 months,X-ray films revealed fracture bony healing,good location of the wire internal fixation,and no apparent shortening of the patella.At the 12 months,range of knee motion was (126.0 ± 4.5) ° for flexion and (2.0 ± 1.7) ° for extension.Bostman functional score for patella fracture was (28.1 ± 1.9) points.And 12 patients were rated as excellent and 2 good,with excellence rate of 100％.Conclusion Cannulated screw fixation plus separate vertical wiring is effective to stabilize patella inferior pole fracture and has good results,indicating a recommended surgical method.
