Acute appendicitis is the most common surgical or acute abdomen in childhood.Rapid and correct diagnosis is the premise of rational therapy,but there are still some problems in diagnosis and differential diagnosis.Sufficient comprehension about clinical features and differential diagnostic diseases,typical clinical symptoms,physical examination,laboratory examinations,ultrasonography or CT would make a definite diagnosis.Laparoscopy is also used to make a diagnosis if necessary.

Objective To investigate the intakes of dietary nutrients and the growth and development status among children with autism,to propose scientific basis for developing further interventions.Methods Dietary intakes of nutrients were obtained with the method of 24-hour dietary review for 3 days.Meanwhile,the height and weight were detected among the subjects;Z-score was also adopted to evaluate nutritional status.Results 1.About 31.5% of the 111 cases with autism were overweight or obesity and 8.1% of the children were acute or chronic malnutrition.2.The intakes of 11 nutrients were insufficient,especially VA,VC,VB6,folate,calcium and zinc,had a serious shortage that less than 60% of the recommended intakes.3.The crowd was widespread lack of nutrients,39.6% of the cases with nutritional deficiency in varying degrees,the incidences of calcium and zinc deficiency were reach up to 88%.Conclusions The nutritional deficiency and overnutrition were simultaneous among the children with autism,their dietary nutritional supplement were generally inadequate.More sufficient measures and rational diet are necessary to improve the nutritional status for the autistic children.

Objective To evaluate the effects of nursing intervention on the beliefs and behavior of early detection of breast cancer. Methods Four communities in Shanghai were selected by convenient sampling process. Then these four communities were randomly assigned to intervention group and control group. One hundred and eighty women who met the criteria of this study were selected from each group by convenient sampling process.Altogether 739 women were recruited. In intervention group,a one-year nursing intervention guided by health belief model was implemented,such as health education seminars,telephone follow in the third,sixth,and ninth months,and flyers of breast health care in the sixth month. Control group only received conventional education. Results After intervention women became aware of breast cancer (B=0.210,P＜0.01),perceived more benefits from attending early breast cancer detection (B=0.105,P＜0.01),and less difficulties in attending the activities of early detection of breast cancer (B=-0.086,P＜0.05). The number of women who performed breast self-examination once per month increased and more women received clinical breast examination (OR=3.0946) and mammogram after intervention (OR=2.746). Conclusion The nursing intervention,guided by health belief model,is helpful to improve women's beliefs and behaviors of breast cancer detection.

Objective To investigate clinical biologic characteristics and factors that impact prognosis of patients with follicular thyroid carcinoma(FTC).Method Clinical data of 105 FTC patients treated surgically in the Department of Head& Neck,Tianjin Cancer Hospital from 1970 to 1990 was analyzed retrospectively.Results The overall 5-year,10-year and 15-year survival rates of these patients were 85.3％,76.7％ and 72.9％ respectively.The overall 15-year survival rates of patients ≥45 years and those ＜ 45 years were 45.9％,89.8％ respectively.The overall 15-year survival rates of patients with unilateral and bilateral carcinoma was 50.0％,76.2％ respectively.The overall 15-year survival rates of patients with neck lymph node metastasis and without were 54.2％,79.2％ respectively.The overall 15-year survival rates of patients at stage Ⅰ,stage Ⅱ,stageⅢ and stageⅣ were 89.3％,70.0％,45.5％ and 35.3％respectively.During the follow-up period,11 patients were diagnosed with distant metastasis from 1 year to 33 years after surgical treatment and 9 died of cancer within 5 years after diagnosis.Seventeen patients had local recurrence from 3 months to 34 years after surgery and 10 of these patients died of local recurrence.Conclusions The factors influencing prognosis of patients with FTC were age,clinical stage,bilateral carcinoma and neck lymph node metastasis,therefore early treatment and close following-up are essential to improve the prognosis of patients with FTC.

Objective To find out the brain function characters of visual information integration and visual working memory with attention deficit hyperactivity disorder (ADHD) children. Methods 1∶ 1 case-control study was used on the study. 45 ADHD children who met DSM-IV criteria were recruited as case group,45 normal children from primary school were chosen as control group. Two groups children received the test of contour-integration,positional noise, temporal order memory, pattern memory. Results The ADHD double eyes' contour integration ( ( 1.62 ± 0. 81 ), ( 1.69 ± 0.87 ) ) were significantly lower than the control group' ( (2.02 ± 1.10), ( 1.98 ±0.81 )). There was no significant difference of double eyes' positional noise between case group( (1.98 ±0.89 ), ( 2.20 ± 1.10 ) ) and the control group ( ( 2.20 ± 0. 97 ), ( 2.30 ± 0. 83 ) ). The temporal order memory,pattern memory ( ( 1.89 ± 1.30), ( 1.18 ± 0.44) ) showed significantly lower in case group(P＜ 0.05 ) than that in control group ( ( 2.98 ± 1.25 ), ( 1. 44 ± 0. 66) ). Conclusion Results indicate that children with ADHD have deficiency in visual perception and the ability of visual information integration, and have significantly deficiency in visual working memory and executive-function.

Objective To explore the EEG characteristics and the correlation between EEG characteristics and visual attention function in attention deficit/hyperactivity disorder(ADHD).Methods 1:1 case-control study wag applied(37 ADHD children were compared with 37 healthy control groups).Participants aged from 6 to 14 years were involved in this study.All children were tested EEG characteristics and visual function,including the frequency,amplitude,relative power and counting missing features test.And the correlation was analyzed between relative power and visual function.Results The θ amplitude((20.48±14.99μV)in ADHD wag significantly higher than that in the control group((12.37±8.06)μV),(P<0.05);the β frequency((16.63±1.72)Hz) in ADHD was significantly lower than that in the control group((16.63±1.72)Hz,P<0.05);the relative power of β in ADHD(5.24±1.24)was significantly lower than that in the control group(6.30±1.19),(P<0.05);the θ/β ratio in ADHD(4.22±1.26)was significantly higher than that in the control group(3.41±0.52)(P<0.05);the double eyes'counting missing features mark(56.76±19.16),(49.73±23.39) in ADHD were significantly lower than that in the control group(72.43 ±17.23),(71.35±16.69).There wag significant negative correlation between the θ relative power and double eyes'counting missing features(r=-0.448 and-0.361);the θ/β ratio had significantly negative correlation with the fight eye's counting missing features(r=-0.352).Conclusion Compare to the normal control group,the ADHD group shows significant difference in EEG characteristics and visual attention function.The change of EEG power characteristics hag a significant affect on the allocation of attention.

Heart rate variability (HRV) is a reliable, innocuous and sensitive new index to measure cardiac autonomic nervous function. Anxiety disorder is often accompanied by autonomic nerve dysfunction and its main sign is abnormal HRV. Acupuncture can affect HRV indices, correct abnormal HRV and improve cardiac autonomic nerve dysfunction to relieve anxiety. This article sorts out and analyzes recent years’ studies on abnormal HRV in anxiety disorder, the effect of acupuncture on HRV and acupuncture regulation of abnormal HRV in anxiety disorder to provide a therapeutic basis for clinical acupuncture intervention in abnormal HRV in anxiety disorder.

Objective To investigate the effect of small interfering RNA (siRNA) suppressing discoidin domain receptor 1 (DDR1) gene on biological behaviour of Kupffer cells (KC) in acute hepatic injury. Methods Male BALB/c mice were randomly divided into control, hepatic injury model, non-silencing siRNA and DDRlsiRNA groups. Hepatic injury model induced by intravenous injection of Con-canavalinA (ConA) 15 mg/kg, with or without hydrodynamic tail intravenous injection of naked siRNA (50 μg,2.0-2.5 mg/kg)/mouse or 1.5 ml normal saline. The expression of DDRI was assayed by West-ern blot and pro-inflammatory cytokine expression analyzed by ELISA. In the meantime, alanine amin-otransferase (ALT) and Kupffer cells'clearance to carbon granules was detected. Results The expres-sion of DDR1 obviously increasod at 6 h after hepatic injury, roached peak at 24 h and began to decrease at 48 h. Pretreatment with DDRisiRNA could obviously inhibit the expression of DDR1 and abrogate the high levels of ALT, expressions of TNF-α and IL-1β as well as phagocytosis of Kupffer cells. Conclu-sions Inhibition of discoidin domain receptor 1 by in vivo delivery of siRNA attenuates ConA-induced hepatic injury. Possible mechanism is that the inhibition of activity of KC inhibits the expression of pro-in-flammatory cytokines and thus alleviates hepatic injury.
