Objective To investigate the ultrasound characteristics of prenatal fetus otocephaly . Methods Three prenatal fetus with otocephaly were examined with two -and three-dimensional ultrasoundand examined results were compared with the those of induced labor or autopsy ,and ultrasound characteristicsof prenatal fetus were analyzed and summarized .Results The ultrasound performance of three prenatal fetuswith otocephaly and the examination of the appearance after induced labor showed :(1) The most intuitiveinitial sonographic performance of otocephaly was manifested by the absence of stomach bubble andoverabundance of amniotic fluid.Among three fetus,one fetus had overabundance of amniotic fluid at the midstageof pregnancy,one fetus had normal amniotic fluid at the mid-stage of pregnancy and one fetus hadextremely high amount of amniotic fluid and absence of stomach bubble at late stage of pregnancy .(2) Allthree fetus showed agnathy and synotia (shifts of both ears to the midline) and microstomia deformity.(3) All three fetus had associated complications with deformity in other systems including two cases of patients withcleft lip and palat,both were the fracture unilateral cleft lip derived from small mouth .One fetus withdysmelia and one fetus with complicated cardiovascular deformity and situs inversus and .(4) The results ofexamination after induced labor or autopsy were consistent with those of the prenatal ultrasound examination . Conclusions Prenatal ultrasound examination is an effective and feasible means for the diagnoses ofotocephaly.When the symptoms of “absence of stomach bubble and extremely high amount of amniotic fluid ”occurred,the fetal ear and submaxilla should be examined to confirm stand -alone otocephaly prenatally.

Objective To explore the status of early postoperative social relationship quality and hope level in patients with breast cancer and analyze the correlation between them. Method A questionnaire survey was conducted among 100 patients with breast cancer using the social relationship quality scale and Herth hope scale. Results The total score and expected total score of early postoperative social relationship were (47.86±6.10)and (30.81±1.86), respectively. There was a positive correlation between the two groups (r=0.324,P<0.05). Conclusions The quality of social relations in the postoperative patients with breast cancer is positively correlated with the level of hope. Nursing staff should give breast cancer patients hope and strength at the same time, helping them understand and use social relations to improve the quality of life.

Objective To analyze and compare the clinical application values of procalcitonin (PCT),leukocyte count (WBC) and C-reactive protein(CRP) in elder patients with infection.Methods In patients(age≥ 65 yrs,axillary temperature ＞38.0℃)with infection or suspected infection,PCT,WBC,CRP and other bacteriological examination were performed.The electronic medical records from the HIS system of our hospital were analyzed retrospectively in combination with medical history.Results Of the enrolled 219 patients,65 ones were in control group,48 ones SIRS,51 ones sepsis and 55 ones MODS.There was a positive correlation between the level of serum PCT and the infection degree.The Spearman correlation coefficient was 0.706 (95％CI:0.616-0.797,P=0.000).Based on the highest Youden index (sensitivity+specificity-1),the best cutoff point of diagnosis for PCT was ＞0.341 μg/L (sensitivity 84.5％,specificity 55.8％),a analysis of receiver operating characteristic(ROC) curve about PCT,WBC and CRP was carried.Area under the curve (AUC) of PCT to controlled infection was 0.916 (95％CI:0.864-0.967,P=0.000).Based on the highest Youden index (sensitivity+ specificity-1),the judging threshold of PCT to infection controlled or not was 0.73 μg/L (sensitivity 84.6％,specificity 88.0％).PCT level after treatment ＞0.73 μg/L showed the uncontrolled infection,＜ 0.73 μg/L controlled.Conclusions PCT has a higher specificity for elder patients with infection.The variation of PCT level can guide the application of antibiotics,avoid abuse and decrease the occurrence of drug-resistant bacteria.

Objective:To investigate the prevalence of volatile sulfur compounds ( VSC ) in oral cavity of preschool children, and to analyze related factors, thus to provide scientific basis for the prediction and treatment of halitosis. Methods:The VSC content ( hydrogen sulfide, methyl mercaptan, dimethyl sul-fide) of 170 preschool children (4 to 6 years old) was detected by a portable gas chromatograph Oral-ChromaTM . The status of the oral health was evaluated. The living habits and other aspects were obtained through questionnaires from the children' s parents. A soft package for social statistics version 13. 0 ( SPSS 13 . 0 ) was used in which univariate analysis and multivariate analysis were utilized to analyze the related factors of halitosis in children. Results:In the study, 34. 4% of the total subjects had excessive VSC. Hydrogen sulfide (H2S) [(1. 59 ± 2. 41) ng/10 mL] and total VSC concentration [(2. 14 ± 4. 42) ng/10 mL] in the girls were significantly higher (P<0. 05) than those in the boys. The tongue coating score had a significant positive correlation with H2S [tongue coating area (1. 68 ± 2. 48) ng/10 mL,tongue coating thickness (2. 18 ± 2. 69) ng/10 mL] and total VSC concentration [ tongue coating area, (2. 26 ± 4. 31) ng/10 mL,tongue coating thickness (2. 41 ± 3. 02) ng/10 mL , P<0. 01]. The site number of DI-S≥2 had a significant positive correlation with methyl mercaptan ( CH3 SH) and dime-thyl sulfide [(CH3)2S] concentration (P<0. 01). The concentration of H2S [(1. 19 ± 1. 62) ng/10 mL] in children, whose mother had a higher degree of education, was statistically lower (P<0. 01).The children who took dessert or sweat drinks more frequently had lower H2S [(1. 04 ± 1. 55) ng/10 mL, P<0. 05] concentration, while CH3SH and (CH3)2S concentration [(0. 29 ± 1. 92) ng/10 mL, (0. 37 ± 2. 06) ng/10 mL, P<0. 05) were higher in the children with mouth -breath habit. Conclu-sion:A high prevalence of halitosis was noted in preschool children. Gender, tongue coating index, deb-ris index-simplified, status of the mother' s education, frequency of eating dessert or sweat drinks and dry mouth breath were related with halitosis of preschool children. The different related factors resulted in changes of each VSC concentration.

AIM:To assess the protective role of melatonin(MEL)in a rat model of oleic-induced acute lung injury.METHODS:Twenty-four rats were randomly allocated to three groups as follows:saline(NS)injection group,oleic acid(OA)injection group and MEL plus OA injection group,the lavage protein,lung wet-to-dry weight ratio,malondialdehyde(MDA)content,superoxide dismutase(SOD)activity and lung histopathology were examined.RESULTS:(1)Injection 0.15 mL/kg of OA led to a severe acute lung injury(ALI),characterized by significantly increasing in lavage protein,lung coefficient(P＜0.01),and by histopathological alterations which presented hemorrhage,edema.thickened alveolar septum and the existence of inflammatory cells in alveolar spaces;(2)Infusion of MEL(20 mg/kg,intraperitoneally for 60 min before the oleic acid)markedly alleviated above-mentioned symptom induced by OA,consistent with decrease of MDA level(P＜0.01) and the increase of SOD activty(P＜0.01).CONCLUSION:Pre-treatment with MEL can attenuate the OA -induced ALI in rats via cleaning and preventing the formation of free radicals and further lessening the increase of alveolocapillary membrane permeability,these data suggest that MEL may be effective in the prevention of ALI.

Objective To have a knowledge of the mutagenicity of contaminates in drinking water in a certain city. Methods Mutagenic activity of organic extracts of source water chloridized water in water plant and tap water from the city were detected with single cell gel-electrophoresis mouse primary hepatocytes in culture were used and Ames test. Results For Ames test the organic extract in 3 liters chloridized water in water plant and tap water samples produced positive result and that in 6 liters source water sample still gave a negative result. For single cell gel-electrophoresis test the organic extract in 0.1 liter chloridized water in water plant tap water and 0.5 liter source water produced positive result. Conclusion The sensitivity of single cell gel-electrophoresis with primary hepatocytes in detection of genotoxicity of cloridized water and source water is much higher than Ames test.
