Male guinea pigs were placed on ordinary or high lipid diet for 30-36 weeks with various amounts of ascorbic acid (Vc) intake. The daily dose of low level intake was 0.7-1.2mg. The normal one was 2.5-5mg. The high dose was 30-45mg. The various amounts of Vc intake did not affect the cholesterol contents in serum and liver. The animals fed low level Vc were without "overt signs of deficiency, but morphological changes of aorta were developed in these animals either on ordinary or high lipid diet. On high lipid diet, the pathological changes of the vessels (aorta and arteriols in cardiac muscles) of animals fed low level of Vc were more severe than those of animals fed normal level, and those of animals fed high dose were the least severe.The result of this study suggested that the presence of a link between Vc and the integrity of the vessels. Prolonged low intake of YC may be regarded as being one of the causal factors in the development of arteriosclerosis. The requirements of Vc for subjects with high cholesterol level may be more than those of normal subjects.

Objective To discuss the etiology,clinical features,diagnosis and treatment of congenital pleural effusion in fetuses and neonates in order to improve the understanding of this disease. Methods Six neonate cases with congenital pleural effusion were retrospectively analyzed in neonates who were admitted to the Department of Neonatolo-gy of the First Affiliated Hospital of Zhengzhou University after birth and the etiology,clinical features,diagnosis and re-lated treatment were analyzed based on literature review. Results Among 6 patients with congenital pleural effusion, chylothorax was found in 3 cases,one of whom had chylothorax,chylous abdominal,21 trisomy syndrome and congenital hypothyroidism,and the etiology of the other 3 cases were unknown. Diagnosis mainly was depended on imaging and la-boratory tests. The number of nucleated cells of hydrothorax or ascites were(1 588 - 13 057)× 106 / L,mainly lympho-cytes. Protein qualitative was( + - + + + ),the chylothorax qualitative test was positive in 3 cases. The liver function showed that the total protein and albumin were decreased in varyig degrees. Conservative or surgical treatment was taken according to the situation of the patients. Among 6 patients,3 cases were cured after treatment,the others gave up treat-ment finally. Conclusions The etiology of congenital pleural effusion was different,and often associated with chromo-somal abnormalities or other malformations,ultrasonography was the main method to diagnose congenital pleural effusion and the patients should be dynamically observed or treated during the antepartum or intrapartum period. If the neonates are found to have pleural effusion in prenatal period early diagnosis and treatment is a best choice.

Abstract: Objective To evaluate the performance of QuantiFERON-TB Gold Plus (QFT-Plus) in screening the prison population for latent tuberculosis infection (LTBI), and analyze the related influencing factors of latent infection, so as to provide the basis for screening the prison population for latent tuberculosis infection. Methods The basic characteristics and screening results of the newly admitted prison population were collected, using QuantiFERON-TB Gold (QFT-GIT) assay as the gold standard. The kappa value and the area under the ROC curve were used to evaluate the detection performance of QFT-Plus. At the same time, Kruskal-Wallis test was used to compare the difference of IFN-γ production between tubes. A logistic regression model was established to analyze the influencing factors of latent tuberculosis infection in the prison population. Results A total of 100 valid subjects were included in this study, and 24 LTBI patients were screened. The median age of the participants was 38 years, with a median LTBI age of 44 years and a median healthy age of 37 years. In addition, the education level was mainly concentrated in college and above. Consistency checks of various screening methods revealed that the highest coincidence rate of QFT-Plus and QFT-GIT detection results was 0.917, with the largest area under the curve at 0.958. The K-W analysis showed that the amount of IFN-γ in QFT-Plus TB tube was significantly higher than that in QFT-GIT TB tube, and the variation range of IFN-γ in QFT-Plus tube was greater. In addition, multivariate analysis showed that increasing age (aOR: 1.046, 95%CI: 1.004-1.089) was a risk factor for LTBI in the prison population, while having an education level of college or above (aOR: 0.263, 95%CI: 0.071-0.972) was a protective factor. Conclusions QFT-Plus, as a newly developed method for detecting LTBI, showed basic consistency with QFT-GIT, and the consistency was higher than that of other skin test methods. However, due to the large variation of IFN-γ production in QFT-Plus, it is still necessary to further explore the diagnostic threshold. In the screening of LTBI in prisons, special attention should be given to the elderly population and the population with low education levels.

Pressed biscuits were fortified with gelatin encapsulated VA powder, VC phosphate Mg and VB2 tetrabutyrate. The biological effects of these vita-rains were examined by human experiments. In 7 days of the experimental period, the subjects of the 1st group (10 male adults) took the fortified biscuit freely which contained 7500 IU VA powder, 5.16 mg B2 tetrabutyrate ( = 3mg VB2) and 308mg VC phosphate ( = 140 mgVC) in 750 g. The 2nd group took 250 g biscuit freely containing the same amount of vitamin and unfortified pressed biscuit. The 3rd group took only the unfortified ones freely. 5 days before or after fhe experimental period the subjects ate vitamin restricted diets. The nutritional status of VB2 was estimated by 24 hrs. urinary VB2 values, that of VC by urinary and fasting plasma VC levels, and that of VA by fasting plasma VA values.The urinary levels of VB2, VC and plasma values of VC of group 1 and 2 at the end of the experimental period were significantly higher than those of the pre-experimental period. They were also higher than those of group 3. On the 5th day of the post-experimental period, the status of VB2 and VC of group 1 and 2 was still better than that of group 3. Because the subjects were not in VA deficiency, the plasma levels of VA were kept steady.The stabilities of these vitamins in the fortified pressed biscuit were compared with those of ordinary vitamins. Stored in 85% RH 32℃ for 20 months, encapsulated VA powder retained 76%, VC phosphate 84%, but the ordinary VA only 14%, VC 29%. Stored in room temp. 75% RH for 2 years, the VA encapsulated powder retained 73%, VC phosphate 96%, but ordinary VA only 8%, VC 22.3%. In room temp. for 2 years, encapsulated VA powder retained 87%, VC phosphate almost did not lost, but ordinary VA retained 8%, VC retained 25% only. The stability of the VB2 tetrabutyrate was almost the same as that of VB2. It was shown by the guinea pig growth experiment that VC phosphate in pressed biscuit stored 20 months possessed the same biological effect as VC crystal.

ObjectiveTo explore the risk factors of obstructive hydrocephalus secondary to intracranial hemorrhage in premature infants.MethodsA total of 304 premature infants were selected who were diagnosed as sever intracranial hemor-rhage (grade III and IV) by cranial bedside ultrasound admitted to our hospital from Jun. 2013 to Sep. 2014. According to wheth-er the obstructive hydrocephalus was followed, all infants were divided into hydrocephalus group (n=59) and non-hydrocephalus group (n=185). The risk factors of obstructive hydrocephalus secondary to intracranial hemorrhage were analyzed and the lateral ventricle size was measured dynamically.ResultsThe univariate analysis showed the factors related with obstructive hydro-cephalus were as follows: gestational age≤32 weeks, birth weight< 1500g, severe asphyxia, cesarean section, RDS, neonatal infection, heart failure, PDA, acidosis, thrombocytopenia, coagulation abnormalities, and intracranial hemorrhage (gradeⅢ orⅣ) (allP<0.05). Multivariate logistic regression analysis showed that acidosis, thrombocytopenia, coagulation abnormalities, gesta-tional age≤ 32 weeks, severe asphyxia, intracranial hemorrhage (gradeⅢ orⅣ) were independent risk factors for obstructive hydrocephalus (OR: 1.76~20.46, allP<0.05). At each time point after birth, the ratio of posterior horn of lateral ventricle was signiifcantly higher in hydrocephalus group than that in non-hydrocephalus group (P<0.05). There were signiifcant differences in the changes of the posterior horn ratio of left or right lateral ventricle with time in hydrocephalus group (P=0.000), increasing at 14 days and reaching the peak at 28 days after birth.ConclusionsThe risk factors for obstructive hydrocephalus secondary to intracranial hemorrhage in neonates are important. Regular and dynamical monitoring of ventricle size by cranial ultrasound is needed in infants with sever intracranial hemorrhage.

Objective To examine the impact on impulsivity trait by monoamine oxidase A variable nucleotide tan?dem repeat (MAOA-VNTR) genotype and children’s abuse experience. Methods The self-reported questionnaire of Bar?ratt Impulsiveness Scale (BIS), Childhood Trauma Questionnaire (CTQ) were conducted in 403 normal Han female adoles?cents from north-west of China. The DNA were extracted from their venous blood sample and were genotyped for the MAOA-VNTR polymorphism. A linear regression model was used to investigate the main effects of MAOA-VNTR and children's abuse, and their interaction effect on impulsivity. Results The main effect of Children’s maltreatment experi?ence on trait impulsivity was significant (P<0.01). The main effect of MAOA-VNTR gene and the interaction between MAOA-VNTR genotype and children's maltreatment experience were insignificant (P>0.05). Conclusion The MAOA-VNTR genotype may not be involved in the female adolescents’impulsivity traits related to childhood maltreat?ment.
