ObjectiveTo study CT features of acute intracranial trauma and changes of hematoma in acute stage. MethodsCT findings of acute intracranial trauma of 152 cases were analyzed. ResultsIn 100 cases with intracranial hematoma, the hematoma enlarged obviously within 5-72 h after trauma in 25 cases; the hematoma enlarged markedly within 72 h-7d after trauma in 3 cases. In 76 cases of cerebral contusion, counter point trauma was found in 17 cases. In 61 cases of subarachnoid hemorrhage, high density in cerebral sulcus was shown in 49 cases. Skull fracture was found in 75 cases. Conclusions Intracranial hematoma may enlarge gradually within 7d after trauma. Cerebral contusion was partially due to counter point trauma. Hemorrhage in cerebral sulcus was demonstrated on CT as increased density in the cerebral sulcus, which is the most important sign of subarachnoid hemorrhage. Hemorrhage in interhemispheric fissure was demonstrated on CT as centipede-line increased density, which is an important sign for differentiating from subdural hematoma. Skull fracture was closely related with lntracranial trauma, which was complicated with adjacent extradural hematoma frequently.

Objective To investigate the characteristics of family environment in children with attention deficit hyperactivity disorder (ADHD) in clinics, and analyse the risk factors for ADHD. Methods Two thousand two hundred and ninety-six children with inattention, hyperactivity or unfavourable school performance were subjected to diagnosis with DSM-Ⅳ criteria in clinics. The characteristics of family environment were investigated by self-prepared questionnaires. The risk factors for ADHD were explored by univariate analysis and noneonditioned multivariate Logistic regression analysis. Results Seven hundred and twenty children were diagnosed with ADHD. There were significant differences in family environment between children with ADHD and those without(P<0.05 or P<0.01). The risk factors for ADHD included discord between parents, parental smoking and maternal depression during pregnancy and after delivery, while older age, female, paternal higher educational background were protective factors for ADHD. Conclusion Unfavourable family environment may be associated with the prevalence of ADHD, and special attention should be paid to the family environment in the treatment of ADHD.

Objective To comprehend the awareness rate and the implementation of risk factors related to Helicobacter pylori (HP) infection in families with children of Helicobacter pylori infection.To analyze the existing problems and formulate effective methods of health education.Methods Totally 558 families infected with HP were investigated with a self-designed structured questionnaire by call-back.Results 527 did not use separate eating tools,350 did not use independent tablewares,14 drank unboiled water,14 did not use bath appliances separately,7 used tooth glasses together,4 did not wash hands before eating and after toilet,no one had mouth-to-mouth feeding.248 children with HP sleeped with their family members and 246 family members used to have HP infections or stomach troubles.Conclusions The families with HP do not establish correct ways of separate eating,so the hospital need to develop multi-channel education.Most families with HP infected children have satisfactory health habits.Nearly half of the children with HP do not sleep in their own beds.Caregivers of children with HP infection should be the capital objects of health education.

Background As a new tonometer,it is necessary to assess the clinical value of Icare rebound tonometer.Objective This study was to compare the intraocular pressure(IOP)values measured by Icare with that measured by GAT,and discuss the clinical value of leare rebound tonometer. Methods IOP measurement was performed on 152 eyes of 78 subjects with suspicious glaucoma,glaucoma,refractive error and normal examinnee by Icare and GAT respectively.The Icare IOP was measured firstly and then the GAT IOP was carried out with the 3-or 5-minute interval.The IOP values were compared between Ieare and GAT.This study was approved by Ethic Committee of Wuhan General Hospital of Chinese PLA.Written informed consent was obtained from each subject prior to this study. Results The mean IOP values of Icare and GAT were(19.16±5.03)mmHg and(18.41±4.52)mmHg respectively.The differences between Icare IOP and CAT IOP were less than or equal to 1 mmHg in 96 of 105 eyes(63.2%).The positive correlation was found between the Icare IOP and GAT IOP(r=0.940,P<0.01).The Ieare IOP was lower than that of GAT when IOPIcare<16 mmHg,however,the IOP of Icare were higher when IOPIcare≥6 mmHg;the IOP of Icare were higher than that of GAT in the total CCT range.The correlation coefficients of IOP of Icare or CAT with CCT were 0.341(P<0.01)and 0.333(P<0.01),respectively. Conclusion Compared with GAT,Icare is more feasible in clinic because it is practicable and reliable.

Objective To study the relationship between microalbuminuria and inflammation media of C-reactive protein(CRP) and interleukin-6(IL-6) in type 2 diabetes mellitus,and to explore the clinical significance.(Methods)Ninety-six patients with type 2 diabetes mellitus were divided into 3 groups according to the urine albumin excretion rate(UAER): normal albuminuria group(NA),microalbuminuria group(MA) and clinical proteinuria group(CP).The serum levels of CRP,IL-6,fasting plasma glucose,creatinine and fasting insulin were measured in all the cases. Results The levels of CRP and IL-6 in MA group were significantly higher than those in NA group(P

Objective:To study the incidence rates of cancer in the urban area of Shijiazhuang city, China in 2012 based on the data of 2,374,827 registered residents. Methods: The incidence of diagnosed cancer cases in 2012 was obtained from the hospital reimbursement database of the medical insurance center of the city by retrieving the records on first-time reimbursement applications for the hospitalization of tumor patients from January 1 to December 31 in 2012. Population census data was obtained from the Population Department of the Shijiazhuang Public Security Bureau. The site-specific and sex-specific age-adjusted incidence rates were calculated. Results:The overall incidence rate, the age-adjusted rate of the Chinese population (ASRC), and the age-adjusted rate of the world population (ASRW) for both men and women were 237.53, 129.86, and 167.71 per 100,000 individuals, respectively. The incidence rate increased with age and peaked in the 75-79 years age groups of men and women at 1,729.42 and 867.35 per 100,000 individuals, respectively. The top ten most frequently diagnosed cancers in males were lung, stomach, colorectal, liver, esophagus, kidney, prostate, leukemia, bladder, as well as lymphoma, whereas those in females were the breast, lung, colorectal, stomach, cervical, uterine body, ovary, lymphoma, esophageal, and liver cancers. The incidence rate and ASRW of all cancers combined in men were 269.05 and 187.52 per 100,000 individuals, whereas those for women were 207.57 and 150.44 per 100 000 individuals, respectively. Compared with the average incidence rates of 31 Chinese cities in 2009, the ASRW of lung, stomach, and colorectal cancers in males from Shijiazhuang was nearly equal to the national level;however, the ASRW of breast cancer in females from Shijiazhuang was higher than the national level. When the incidence rates of Shijiazhuang in 2012 were compared with those of Beijing in 2009, the ASRW of stomach and esophageal cancers in men of Shijiazhuang was twice that of the same cancers in Beijing. However, the same parameters for the pancreatic and prostate cancers in men, as well as the thyroid and uterine body cancers in women of Beijing, were twice the values for Shijiazhuang. Conclusion: The ASRWs of the major types of cancer, such as the lung, stomach, colorectal, and breast cancers, in urban Shijiazhuang in 2012 were identical to those of the 31 Chinese cities in 2009. Compared with Beijing, the incidence rates of pancreatic, prostate, and thyroid cancers were significantly higher in Shijiazhuang, whereas those of esophageal and stomach cancers were significantly lower.

ObjectiveTo study the MRI features of children with cerebral palsy(CP) resulting from anoxia.Methods The clinical and MRI findings in 83 premature or mature children affected by cerebral palsy resulting from PVL were reviewed retrospectively to search for the MRI features and the data were analyzed by statistic. Results1. MRI features of CP children resulting from anoxia were clearly demonstrated:1) MRI features of PVL: reduction of white matter ;T2W signal hyperintensity in white matter; ventricle enlarged or irregular appearance; lateral fissure;deepened or widened Sulci;and abnormal corpus callossum; 2) other abnormal MRI features: basal ganglion damaged; cerebral cortex atrophy or malacia. 2.Differences in MRI features between premature and mature CP children: there are significant differences between premature and mature children at malacia and cyst of deep white matter; enlargement and irregularity of the lateral ventricles. ConclusionsMRI examination can clearly display the level and scope of focus of PVL,and the differences in MRI features between premature and mature children.The level and degree of premature children are deeper and more extensive than those of mature children.Cyst and malacia in deep white matter,enlargement and irregularity of the lateral ventricles occur more frequantly in premature children.

Glucose was transported by the large number of hexose transporters in yeast cells. There were 18 hexose transporter genes had been identified in Saccharomyces cerevisiae. However,as an excellent expression system,there was no information of these genes had been reported in Pichia pastoris. Based on high homologous recombination efficiency in yeast,we chose G418 resistance for screening,200 bp were cloned from the up and down sequences of HXT1 ORF respectively,then ligated to the 5′ and 3′ end of G418 resis-tance gene for recombination. After electroporation of GS115 spheroplast and screened through different G418 concentration plates,finally we obtained one HXT1 gene deletion mutant named GS115?HXT1. The growth rate and glucose consumption of this mutant were both lower than the wide type.

Objective To assess the effectiveness of prevention program on iodine deficiency disorders and iodine nutritional status of residents in Guangdong Province.Methods Probability proportionate to size sampling(PPS) was employed in surveillance of iodine deficiency disorders.Thirty counties(cities,districts) were selected in Guangdong Province.In each county(city,district) one township(street) was selected; in each township (street) one primary school was selected and in each primary school 40 children aged 8-10 were chosen to examine their thyroid and to collect salt samples at their home for determination of salt iodine.Out of the 40 children,12 children were chosen to collect urine samples for determination of urinary iodine.From the primary schools chosen,40 grade 5 students were selected for intelligence quotient(IQ) test.In the nearby of the primary schools,3 townships(towns,street) were selected and in each township(town,street) 5 pregnant and 5 lactating women were selected to collect their urine samples for determination of urinary iodine.Type-B ultrasonic was used in measuring the thyroid volume.The iodine content of urine samples was measured by the method of arsenic and cerium catalysis spectrophotometry.The iodine content of salt was determined quantitatively with the titration method.IQ was tested by Chinese combined Raven's test.According to geographical location and the implementation of iodized salt,the effects of iodized salt on iodine deficiency disorders were analyzed in the plains and the Pearl River Delta Coastal region with mild iodine deficiency(iodized salt implementation region,referred to as the plains and the PRD),historical iodine deficiency areas (iodized implementation region) and the eastern and the western coastal areas of Guangdong(areas with non-iodized salt problem,referred to as the eastern and the western Guangdong).Results A total of 1200 children aged 8 to 10 were examined by type-B ultrasonic test,and goiter rate was 3.5％ (42/1200).The differences of goiter rate between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant (x2 =6.6,P ＜ 0.05).The goiter rate (6.1％) in the eastern and the western Guangdong was significantly higher than that of the plains and the PRD and the historical iodine deficiency areas (3.3％,2.0％,x2 =5.6,7.1,all P ＜ 0.05).A total of 1200 salt samples were examined.The median and coefficient of variation of iodine in the salt were 31.0 mg/kg and 23.2％,respectively.Coverage of iodized salt was 97.5％(1170/1200) while 96.1％(1153/1200) of consumed iodized salt was qualified.The median urinary iodine of 1200 children aged 8-10 was 186.5 μg/L,and the differences of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant(x2 =5.9,P ＜ 0.05).The median urinary iodine of the eastern and the western Guangdong(162.4 μg/L) was significantly lower than that of the plains and the PRD(207.5 μg/L,x2 =8.7,P ＜ 0.01).The difference of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong was statistically significant(x2 =58.9,P＜ 0.01).The median urinary iodine of the eastern and the western Guangdong(109.6 μg/L) was significantly lower than that of the historical iodine deficiency areas and the plains and the PRD(152.9,155.2 μg/L,x2 =18.3,20.6,all P ＜ 0.05).The mean IQ of the 1208 grade 5 students was 102.8 ± 14.3.The IQ of the plains and the PRD(104.3 ± 13.9) and the historical iodine deficiency areas(102.7 ± 14.3) was significantly higher than that of the eastern and the western Guangdong(100.3 ± 14.7,t =3.8,2.1,P＜ 0.01 orP＜ 0.05).Conclusions The goal of iodine deficiency disorders elimination is achieved as scheduled in Guangdong Province.The health level of general population has been improved significantly.Iodine nutrition is in the appropriate range (100-199 μg/L) in general population but low in pregnant women.The selling of non-iodized salt in the eastern and the western Guangdong Province should be followed closely.
