BACKGROUND: Temperament plays an important role in psychological development of children. Generally speaking, temperament is genetically determined, but it is also influenced by some other factors. The influential factors studies of temperament are important to promote psychological development and reduce behavior problems of children.OBJECTIVE: To explore the correlation between breastfeeding and temperamental characteristics in children aged 4-5 years old.DESIGN: Random cluster sampling.SETTING: Affiliated Hospital of Medical College, Qingdao University, Zibo Central Hospital, and Research Institute of Pediatrics, Medical College of Qingdao University.PARTICIPANTS: 737 children (399 males, 338 females) aged 4-5 years old from 8 kindergartens of 4 districts in Zibo were selected from March to June 2005. All the subjects and their parents were informed about the experimental goal.METHODS: With stratified random cluster sampling, 737 children were investigated by NYLS 3-7 years old children temperament questionnaire and self-made inventory questionnaire. The association of 9 dimensions including adaptability, rhythmicity (regularity), activity level, persistence, quality of mood, approach and withdrawal, intension of reaction, distractibility and threshold of responsiveness with feeding type in the first 4 months after birth and duration of breastfeeding was analyzed; the multiple gradual regressive analysis was carried out with each dimension of temperament as the dependent variable and feeding type in the first 4 months after birth and duration of breastfeeding etc. as the independent variables.MAIN OUTCOME MEASURES: Temperamental dimension, feeding categories in the fist 4 months, and breastfeeding duration.RESULTS: All 737 children were involved in the result analysis. Correlation analysis indicated that temperamental adaptability was positively related with formula milk mainly in the first 4 months after birth (r =0.084, P =0.030);Rhythmicity and distractibility were negatively related with formula milk only (r =-0.087, -0.075, P =0.022, 0.047);Activity level were positively related with breast milk only and negatively with both breast milk and formula milk equally (r =0.084, -0.077, P =0.030, 0.045); Approach and withdrawal was negatively related with breast milk mainly (r =-0.097, P =0.012). Rhythmicity, quality of mood and activity level were negatively related with breastfeeding for 4-6 months (r =-0.082, -0.102, -0.153, P =0.036, 0.009, 0.001); Quality of mood and activity level were positively related with the duration of breastfeeding more than 9 months (r =0.089, 0.088, P =0.024,0.025). After rectifying the family structure, and educational level of parents, the influencing factor of adaptability was formula mainly; intensity of reaction was breastfeeding duration for 4-6 months and breast milk mainly;rhythmicity was breastfeeding duration for 7-9 months and formula only; activity level was both breast milk and formula milk equally and breastfeeding duration for 7-9 months; quality of mood was formula only and duration of breastfeeding for 7-9 months; approach-withdrawal was breast milk mainly and both breast milk and formula milk equally; distractibility was formula milk mainly.CONCLUSION: Temperamental development of children aged 4-5 years old is related to feeding type in the first 4 months after birth and duration of breastfeeding; therefore, it is essential to pay attention to breastfeeding during temperamental cultivation and intervention.

Objective To evaluate the damaging degree of hepatic cell in the patients with hepatocirrhosis. Methods 25 cases of hepatocirrhosis and 13 eases of normal controls were performed the dynamic imaging with 99mTc-EHIDA.By the three compartmental model configurations,the time-activity curers of the liver cell,and the function indexes liver cell extraction and excretion were calculated.Results The peak time and mean residence time in the hepatocirrhosis group were higher than those in the normal controls(P＜0.01).Compared to normal controls, the peak value,index of uptake,take slope,and excretion slope of the hepatocirrhosis were all lower(P＜0.01).Con- clusion Liver cell imaging is a better method for reflecting the change of liver cell function,and may be used to analyse the degree of hepatocirrhosis.

This retrospective study was designed to analyze the early therapeutic outcome of radioiodine therapy in patients with Graves'disease. According to the follow up result after one year treatment, patients were divided into two groups on the basis of whether there was signs of hypothyroidism. 46 patients with hypothyroidism, 60 patients without hypothyroidism were selected randomly. The SAS software was used to assess the outcome of early hypothyroidism and the thyroid weight, the peak of 131 I uptake, absorption value by per gram of thyroid tissue, thyroglobulin autoantibody (TGA), and thyroid microsome autoantibody (TMA) levels. Rank sum test, t test and ? 2 test were used to compare the variable parameters between the two groups. Thyroid weight ( P =0 0106) and the peak of 131 I uptake ( t =2 1725, P =0 0321) between two groups had significant difference. The absorption value of the thyroid tissue ( P =0 4420), thyroid autoantibody (? 2 =1 156, P =0 282) had no significant difference between two groups. Patients with smaller gland weight and lower 131 I uptake had an inclination to have early hypothyroidism. Absorption value by per gram of thyroid, TGA and TMA levels had no influence on the outcome of 131 I treatment

Objective To evaluate the development of early hypothyroidism of patients with hyperthyroidism after radioiodine131 therapy, its outcome and predisposing factors. Methods Sixty-one patients manifesting early hypothyroidism after treatment with 131 I were followed-up for over one year, and they were divided into two groups: temporary hypothroidism group (including those who had attained normal thyroid function and those with recurrent hyperthyroidism), and permanent hypothyroidism. The duration between treatment and appearance of hypothyroidism, gender, thyroglobulin antibody (TGA) and thyroid microsome auto-antibody (TMA) levels, thyroid weight, total dosage of 131 I, and peak of 131 I intake were compared between two groups. Results Over one half of the 61 patients manifested temporary hypothyroidism (3.3% with recurrent hyperthyroidism, 50.4% of them attained normal thyroid function). Based on the length of the interval between the beginning of the treatment and onset of hypothyroidism, they could be categorized into ≤3 month, 4～6 months became permanent hypothyroidic. The above indises determined during the treatment did not show relationship with the outcome. Conclusion It was therefore concluded that the time of appearance of hypothyroidism was the main factor which determined the outcome of 131 I therapy so far as hypothyroidism was concerned.

Objective To investigate the clinical manifestation and diagnosis of Hashimoto thyroiditis (HT). Methods 45 HT patients diagnosed by fine needle aspiration cytology (FNAC) were enrolled in this study. Their medical history, clinical parameters, data of laboratory examination, colour doppler ultrasonic image and FNAC were analyzed. Results This disease was more common in women than in men, and most of cases occurred during 35～50 years old. Almost all cases had the symptoms of thyromegaly and laryngopharynx malaise. The patients had normal thyroid function, hypothyroidism or hyperthyroidism. The levels of both antithyroid globulin antibody and antithyroid microsome antibody increased in 39 cases. The ultrasonic imaging features of thyroid were such as following: diffusive nonhomogenous hypoecho pattern in 19 cases, numerous hypoecho micronodes in 15 cases, hyperecho micronodes in 3 cases, and hyperecho bandlike echo pattern with swelling of neck lymph nodes in 8 cases. Conclusion Diagnosis of HD should put emphasis on a complete medical history, physical examination and necessary laboratory tests. Antithyroid auto-antibody assay and thyroid ultrasonic examination were very important for diagnosis of HD, and FNAC may be indispensable in suspected cases.

Methods The pregnant Japan long ear white rabbits were divided randomly into cocaine group( N =12) and normal control( N =12). Pregnant rabbits were treated with cocaine hydrochloride 5 mg/kg or normal saline 1 ml/kg intravenously, one time daily from day 15 of pregnancy until day 30 respectively. Serum aspartate aminotransferase(AST), albumin(ALB), total bilirubin(T BIL), hepatic glutathione(GSH) were examined. Results (1)The levels of serum AST, T-BIL were significantly higher in the cocaine group than that in the control group( P

ObjectiveTo observe the effect of the treatment of neodymium-yttrium aluminum garne (Nd:YAG) vitreolysis for the anterior vitreous opacity after implantation of intraocular lens.MethodsForty-nine eyes of 47 patients with the anterior vitreous opacity after implantation of intraocular lens received the slit lamp examination, optical coherence tomography (OCT), and B-scan. The anterior vitreolysis and posterior capsulotomy were performed simultaneously with Nd:YAG laser. The outcomes of visual acuitiy changes and complications were studied. ResultsIn 49 eyes, 46 had anterior vitreous opacity associated with posterior capsule opacification, and the other 3 without obvious posterior capsule opacification. In all patients, the visual acuity improved significantly without any complications after the laser procedure (t=32.50, P=0.007). After Nd:YAG laser treatmen, transparent area was found in anterior opaque vitreous in 21 eyes (42.86%) within 15 minutes, and in 47 eyes (95.92%) within 24 hours. No complication occured in or after the operation. ConclusionsIn the patients with visual deterioration after implantation of intraocular lens, the prescence of anterior vitreous opacity should be concerned. Opening the opaque anterior vitreous with Nd:YAG vitreolysis is effective for the patients with the anterior vitreous opacity after implantation of intraocular lens.

Clinical records of a patient with olfactory neuroblastoma presented with hyponatremia as initial symptoms were analyzed and the literatures were reviewed. At initial onset, the patient presented with hyponatremia. After pathological examination, the diagnosis was olfactory neuroblastoma. The blood sodium has been normal after operation and radiotherapy. The incidence rate of olfactory neuroblastoma is low, and it is easily misdiagnosed. Its diagnosis relies on pathological examination. We should pay more attention to the unspecific symptoms of patients with hyponatremia, which can help to improve early diagnosis and the prognosis.
