ABSTRACT
Objective To study the population's iodine nutritional status of Yanping area of Nanping City,Fujian Province,and to provide scientific basis for prevention and control of iodine deficiency disorders (IDD).Methods According to 2014 Key Population Iodine Nutrition in Fujian Province and the Related Health Monitoring Programme,five subareas were selected according to the five directions as east,west,south,north and centre in Yanping area,and one township was selected in each subarea.In addition,one subdistrict administrative office was chosen in urban area,and one neighborhood committee was selected as a monitoring site.Water iodine detection:two water samples from centralized water supply pipe were collected in selected townships and subdistrict administrative office,and arsenic cerium catalytic spectrophotometry was used to detect the level of water iodine.Salt iodine detection:four administrative villages were selected in each monitoring township,15 households were selected in each village,and a total of 300 households were selected;and 31 households were selected in urban area.The General Test Method for Determination of Iodine in Salt Industry (GB/T 13025.7-1999) was used to detect the level of edible salt iodine.Urinary iodine detection:①children aged 8-10 years old:one primary school was chosen in each monitoring township,30 children aged 8 to 10 were selected in each primary school,and a total of 150 children (half males and half females) were selected;one primary school was chosen in monitoring urban area,and 100 children (half males and half females) aged 8 to 10 were selected;②pregnant women and nursing mothers:20 pregnant women in each monitoring village were selected,and a total of 100 pregnant women were selected;50 pregnant women and 50 nursing mothers were selected in urban area;③adults aged 18 to 45 years old:50 adults (half males and half females) were selected in urban area.Urine samples at random times during the day were collected,and Arsenic Cerium Catalytic Spectrophotometry for Test of Urinary Iodine (WS/T 107-2006) was used to detect the level of urinary iodine.Goiter examination of children aged 8 to 10:palpation was used to examine goiter of all children.Results A total of 12 drinking water samples were collected,the levels of water iodine were all ＜ 3.5 μg/L.A total of 331 edible salt samples were collected,the median of salt iodine was 23.3 mg/kg,iodized salt coverage rate was 100.0％ (331/331),and qualified iodized salt consumption rate was 93.1％ (308/331).A total of 250 children were examined by the thyroid palpation,the rate of goiter was 0.8％ (2/250);the median of urinary iodine was 174.0 μg/L;the medians of children in rural and urban areas were 192.3 and 155.7 μg/L,respectively,the difference was statistically significant (Z =-3.582,P ＜ 0.01),and urinary iodine level of rural children was higher than that of urban children.Totally 150 pregnant women urine samples,50 nursing mothers urine samples,52 adults urine samples were collected,respectively,the medians were 143.7,116.2 and 115.6 μg/L,respectively,urinary iodine of pregnant women was lower than national standard (≥ 150 μg/L).Conclusions The population's iodine nutrition level is appropriate.At the same time,there are special people (pregnant women) at risk of iodine deficiency.
ABSTRACT
Objective To investigate the pathogenic bacteria distribution, antibiotics resistance, and clinical features of childhood bacterial meningitis (BM). Methods Clinical data from BM children with positive cerebrospinal lfuid culture were retrospectively analyzed from March 2004 to March 2015. According to age, the BM children were divided into neonates group (0-28 days), infants group (—1 year), and children group (≥1 year). According to the onset time, the BM children were divided into the early group (March 2004 to March 2010) and the late group (April 2010 to March 2015). According to the clinical situation, the BM children were divided into the trauma and surgery secondary infection group and the control group. Results A total of 100 BM children were recruited. One hundred and two strains of pathogens were detected, 62 (60.8%) strains of Gram positive bacteria and 40 (39.2%) strains of Gram negative bacteria. The main pathogens were Streptococcus pneumoniae (33 strains), Escherichia coli (22 strains), and Streptococcus agalactiae (10 strains). The proportion of Streptococcus agalactiae was higher in the late group (18.8%(9 cases)) than that in the early group (1.9%(1 case)) (χ2=6.406, P=0.011). The proportion of coagulase-negative staphylococci was higher in the trauma and surgery secondary infection group than that in the control group (χ2=6.631, P=0.010). Drug sensitivity analysis found that 60.0%of Escherichia coli produced extended-spectrumβ-lactamases (ESBLs) in the control group, while the only one strain of Escherichia coli in the trauma and surgery secondary infection group was ESBLs negative. Streptococcus pneumoniae were sensitive to vancomycin and linezolid. Streptococcus agalactiae were all found in the control group, which were all sensitive to penicillin and linezolid. The sensitive rate to vancomycin was only 70%. The incidence of complications in neonates group, infants group, and children group was 55.0%(22/40), 78.6%(33/42), and 33.3%(6/18), respectively. The difference was statistically signiifcant (χ2=11.848, P<0.05). The most common complications in these three age groups were ventricular dilatation (40.9%), subdural effusion (45.5%), and hydrocephalus (40.0%), respectively. Thirty-ifve children were cured, 41 children were improved and discharged, 22 children were not cured and left the hospital, and 2 children died. Conclusions Streptococcus pneumoniae, Escherichia coli, and Streptococcus agalactiae were the predominant pathogens in childhood BM. The Streptococcus agalactiae infection is increased in the late group. The complications is varied in different age groups..
ABSTRACT
Objective To assess the value of multi-slice spiral CT in the diagnosis of hepatic venous outflow obstruction (HVO) after liver transplantation. Methods Five patients with HVO were confirmed with digital subtraction angiography and epigastric tri-phase contrast-enhanced CT scans within 4-102 days after liver transplantation, and the CT dynamic enhancement features were retrospectively evaluated. Results Among 5 patients, 2 had middle hepatic vein obstruction, 1 had left hepatic vein obstruction, 1 had right hepatic vein obstruction, and 1 had middle hepatic vein and inferior caval vein obstruction. Contrast-enhanced CT showed typical liver congestion in all 5 patients. The liver parenchyma drained by obstructed hepatic vein was low-density on CT plain scans (1 patient showed mix-density caused by liver parenchyma hemorrhage), while no enhancement on artery phase, moderate enhancement on venous phase and high enhancement on delay phase were observed. During the venous phase, peripheral portal branches were invariably enhanced in the congested area of liver parenchyma. During the delay phase, opacification of the obstructed hepatic vein could be seen. After all patients had treated with interventional therapy, their clinical symptoms were improved, and 2 patients received contrast-enhanced CT scans after interventional therapy, which showed liver congestion relieved and obstructed hepatic vein opacificated well in venous phase. Conclusion Multi-slice spiral dynamic enhancement CT scans can accurately display the location of HVO and the extent of liver congestion.
ABSTRACT
Objectivestudy the influence of nursing intervention on the anxiety among patients with hyperplasia of mammary glands. Methods Divided 200 patients with hyperplasia of mammary glands into the experimental group and the control group, there were 100 cases in the each group. The nursing intervention was used in the experimental group before the examination and the routine nursing cares were used in the control group. Using the HAMA scale to evaluated the anxiety of the two groups. Results The anxiety in the experimental group was significant better than that of in the control group,P
ABSTRACT
Objective To investigate a kind of new operation style aiming directly at middle and late stage cardic cancer. Methods To use the routine resection and retrograde resection simultaneusly as surgical treatment for those difficult to be exercised. Results This is no exploration case in this group. There is no case perioperation death. This method has improved the patient's epitite and quality of life (QOL)obviously. Conclusion This operation style provided a new kind of effective method for the treatment of middle and late stage cardic cancer. It set a solid foundation for improving the patient's QOL and combined treatment after the operation.
