Objective To investigate the new epidemiology and clinical manifestation of measles in children in recent years. Methods One hundred and twenty-eight cases of children′s measles were collected,and their epidemiological and clinical characteristics of age distribution,endemic distribution,vaccination,clinical manifestation,complication and misdiagnosis were discussed. Results Among the patients living in urban,90% cases were single dose vaccination,35% cases were between 3-8 years old,27% cases were less than 8 months old,59% cases were mild measles,27% cases were atypical measles,40% cases were misdiagnosed at first visit,and 67% cases of measles less than 8 months old were babies of vaccine immunized mother.Among the patients living in rural,68% cases had no vaccination,86% cases were at age of typical onset,61% cases were typical measles,7% cases were severe measles,and 28% cases were mild measles.Among all cases of measles,mild measles and atypical measles were as high as 41% and 16%,but typical measles were only 37%.In all patients,56% cases had typical measles rash,82% cases had Koplik′s spots,77% cases had typical onset of eruption,100% cases had higher fever in eruption stage,89% cases had typical downward sequence of eruption,93% cases had skin pigmentation,and 81% cases had desquamation. Conclusions Less than 8 months infants and single dose vaccinated pre-school children are newly susceptible group of measles.Mild measles and atypical measles markedly increased,with atypical clinical symptoms,variable rash and variant onset,but the character of aggravated fever in eruption stage scarcely changes.Infants of vaccine immunized mother and pre-school children are advised to vaccinate ahead of schedule.

Objective To investigate the effects of ketogenic amino acid ( KAA) replacement diet on insulin resistance in mice fed with high fat diet(HFD) and to analyze the possible mechanism. Methods C57BL mice were fed with a control diet, HFD, and KAA-fortified HFD(HFDKAAR)from the age of 8 weeks, and 8 weeks after HFD initiation, the HFD-fed mice were divided into two groups:one group of mice were fed the same HFD, the other group were fed HFDKAAR ( HFD→HFDKAAR ) . The metabolic evaluations were performed at the end of 16 weeks. Blood glucose levels were measured at 0, 15, 30, 60, 90, and 120 min after the injection of glucose ( 1 g/kg BW intraperitoneal glucose tolerance test, ipGTT) . The insulin,β-hydroxybutyrate, and acetoacetate levels in the plasma were measured via ELISA. The insulin resistance index ( IRI) and area under curve ( AUC) were calculated. The expression of hepatic LKB1 ( liver kinase B1 ) , AMP-activated protein kinase ( AMPK ) , and mTOR ( Mammalian target of rapamycin ) protein, and mcp-1 mRNA were measured by western blot and real-time PCR respectively. Results HFD-fed group of mice displayed significantly heavier body weight,heavier intra-abdominal fat weight, and significant deterioration of glucose tolerance at the end of 16 weeks in addition to higher insulin levels( all P<0. 05), HFDKAAR-fed mice exhibited significantly ameliorated high fat diet-induced obesity and glucose intolerance compared to the HFD-fed mice, which was associated with decreased insulin levels, IRI, AUC, and mcp-1 mRNA expression (all P<0. 05). HFD suppressed hepatic LKB1 and AMPK phosphorylation expression, and increased mTOR phosphorylation levels compared to the control diet-fed mice(all P<0. 05). In contrast, treatment with the HFDKAAR diet increased LKB1and p-AMPK expression, which was associated with suppressed p-mTOR levels compared to the HFD-fed mice(all P<0. 05). Conclusion KAA may ameliorate high fat diet-induced obesity, glucose intolerance, via normalizing the hepatic LKB1-AMPK-mTOR nutritional signal passageway. KAA replacement diet seems to be a potential nutritional intervention for the treatment for patients with metabolic defects, such as obesity, glucose intolerance, as well as metabolic syndrome.

ObjectiveTo investigate the application of rapid immunohistochemical staining technique in intraoperative frozen section diagnosis of thyroid neoplasm.Methods MaxVision one-step rapid immunohistochemical staining technique was used to detect the expression of CK19,HBME-1,and Gal-3 in frozen section of papillary thyroid carcinoma(PTC)andthyroid benign lesions.MaxVision conventional immunohistochemistry of frozen remaining tissue was served as control.ResultsMaxVision one-step rapid immunohistochemical staining technique could be completed in 20 minutes.The positive localizations of three markers detected by rapid immunohistochemistry were similar to conventional immunohistochemistry, in general.The expression of CK19 was located in cytoplasm and cellular membrane.Gal-3 and HBME-1 were mainly detected in follicular luminal border and/or surface of papilla. The staining intensity in rapid immunohistochemistry was stronger than that in conventional immunohistochemistry. The positive rates of CK19,HBME-1,and Gal-3 by rapid immunohistochemistry in frozen sections were: 0 (0/28),10.7 ％ (3/28),0 (0/28),respectively,for benign lesions (nodular goiter,Hashimoto thyroiditis,thyroid adenoma); and 94.9 ％(37/39),92.3 ％ (36/39),92.3 ％ (36/39),respectively,for PTC.The expression of three markers between thyroid benign lesions and PTC had a significant difference (x2 =59.326,55.861,44.605,all P ＜ 0.001).In benign lesions,the rate of same case with two and more positive markers was 0,while in PTC it was 100 ％ and significantly different (x2 =67.000,P ＜ 0.05).ConclusionMaxVision one-step rapid immunohistochemical staining technique could be applied in intraoperative frozen section diagnosis.Detecting CK19,HBME-1,and Gal-3 expression in intraoperative frozen section has an auxiliary value for diagnosis of PTC.

Objective To explore the clinical manifestations of ultrasonography(US),99mTc-methoxyisobutylisonitrile(99mTc-MIBI),and 131I whole body scan(131I-WBS)of patients with differentiated thyroid carcinoma(DTC)and cervical lymph node metastasis.Methods A total of 117 cases received examinations of US and 99mTc-MIBI before uses of 131I and received 131I-WBS after 6 d of 131I treatment.Combined with serum thyroglobulin(Tg),131I-SPECT/CT,lymph node biopsy and clinical follow-up of patients,cervical lymph node metastases were identified.Results In 117 patients,the sensitivity of US,99mTc-MIBI and 131I-WBS were 76.5%,67.1% and 83.5%(P

AlM: To describe the expression of hypoxia-inducible factor-1α ( HlF-1α) and erythropoietin ( EPO ) in rats' corneal and evaluate its potential effect on corneal neovascularization ( CNV) growth.
METHODS:The young SD rats (3mo) was chosen and randomly divided into 2 groups, which were experimental group and normal control group. CNV model was established by alkali burn, and the length and area of CNV was observed everyday after operation by slit lamp. After that, the expression of HlF-1α and EPO was measured by SABC and RT-PCR methods at 1, 3, 5, 7, and 14d after alkali burn. The data was analyzed by SPSS 20. 0.
RESULTS:The area of CNV was increasing at 1, 3, 5, 7, and 14d after alkali burn, and the peak point appear at 7d. The growth speed was decreased after 14d. SABC method told us that no HlF-1αand very tiny amount EPO was detected at normal rats' corneal. The expression of the two factors increased at 1d after alkali burn in corneal epithelium and endoderm. The results of RT - PCR showed that a few amounts of HlF-1α and EPO mRNA were detected at normal group. The expression of the two factors was increased at 3d after alkali burn, and the peak value was found at 7d, however, it was decreased at 14d. Statistical difference was found at different time (P<0. 05).
CONCLUSlON: HlF- 1α and EPO is closely related to CNV.

?AIM: To discuss the effect of laser exposure on visual acuity and macula.?METHODS: Retrospective and consecutive case series. A retrospective analysis of 11 patients (11 eyes) with laser retinal injury was carried out from January 2014 to June 2015 in Ophthalmology Department of No. 474 Hospital of Chinese PLA. All individuals underwent visual acuity, best corrected visual acuity ( BCVA ) , and spectral-domain optical coherence tomography ( SD-OCT) for macular at first visit, and fundus fluorescein angiography ( FFA ) , visual field, and multifocal electroretinogram ( mf ERG ) were perform if necessary. Symptomatic therapies, supportive therapies and pars plana vitrectomy ( PPV ) were performed depended on the patient’s condition. The patients were followed-up at 1, 3 and 6mo after the first visit, and patients were undertaken visual acuity, BCVA, macular SD-OCT and so on.?RESULTS: Eight patients ( 73%) were under 18 years old and all patients were young males, who were injured by laser pointers when playing. Three patients ( 27%) over 18 years old were injured accidentally at work. Ten (91%) patients’ BCVA were ≤0. 3, while one ( 9%) patient’s BCVA was higher ≥0. 3. Full-thickness macular holes ( the diameter 224-519 μm ) were detected in 10 patients (91%), while sub-foveal RPE changes and IS/OS injury in 1 patient ( 9%) . Macular hole with traction or cystoid edema in 6 eyes (55%) were received PPV, while the other 5 eyes ( 4 eyes with stable macular hole and 1 eyes with RPE injury ) received conservative treatment. Macular hole closed successfully in 1 eye ( 17%) after PPV, while macular hole in the other 5 eyes ( 83%) were stable after PPV of which the cystoid edema faded. The 4 patients with macular hole and 1 patient with RPE injury were stable during follow-up period. However, the BCVA in all patients had no significant improvement at end.?CONCLUSION: Exposure to laser devices could lead to severe macula injury that could reduce central vision, which is permanent.

Objective To predict the secondary structure and the B cell epitopes of human heparanase protein, and to identify its immunogenicity. Methods The flexible regions of secondary structure and the B cell epitopes of human heparanase amino acid sequence were predicted by DNAStar and Bcepred software. The multiple antigenic peptides (MAP) of the epitopes were synthesized in 8-branch form. Rabbits were immunized with the 8-branch MAPs mixed with a universal T-helper epitope human IL-1β peptide (VQGEESNDK, amino acid 163-171 ). The immunogenicity of the synthesized peptides was evaluated by ELISA, Western blot and immunohistochemistry. Results Amino acid 1 -15 ( MAP1), 279-293 (MAP2) and 175-189(MAP3) of large-subunit of human heparanase protein was predicted as the most potential epitopes of human heparanase protein. All the three synthesized MAPs induced high titer of antibodies. ELISA, Western blot and immunohistochemistry analysis showed all the three MAPs could produce high titer serum antibodies, antibodies induced by MAP1 and MAP2 had high specific binding activity , and MAP2 antibody showed the strongest binding activity with liver cancer tissues. Conclusion The large-subunit No. 1-15, 279-293 amino acid of human heparanase protein may be the B cell preponderant epitopes and the strongest immunogenicity may be No. 279-293 peptide, which provided a theoretic basis for the antibody and vaccine development of heparanase subunit peptide.

Objective To measure the reconstructed cranial CT images,and to clarify the safety range of unilateral nasal transsphenoidal approach for pituitary surgery.Methods 100 normal pituitary cranial CT images were randomly selected,and the three-dimensional reconstruction was performed by using the CT images of perpendicular and parallel to the edge of the two eyes as base line, and the distance and angle in unilateral nasal transsphenoidal approach for pituitary surgery from the sagittal plane in the middle of the nasal meatus and the plane through the tip of the nose and both ends of dorsum sellae were measured,respectively. The angles and distances were compared when grouped the data by gender and age. Results Angle A1 (the angle between the tip of the nose and the tuberculum sellae and saddle back root line in the sagittal plane)in the sagittal plane of the middle nasal meatus was (11.22±1.35)°,95% confidence interval was 8.92°-13.76°degrees;the distance D1(the distance on the line between tuberculum sellae and saddle back root, and the line was formed by the plate contained the angle A1 and sellar floor)was (16.71 ± 2.07)mm,95% confidence interval was 13.11-19.93 mm.Angle A2 (the angle between the tip of the nose and the saddle back ends)which was in the plane through the tip of the nose and both ends of dorsum sellae was (8.91±1.19)°,95% confidence interval was 7.12°-10.72°;the distance D2(the distance on the line between the saddle back ends,and the line was formed by the plate contained the angle A2 and sellar floor)was (14.23±2.09)mm,95% confidence interval was 10.81-17.92 mm. The four parameter data was normally distributed,and there was no significantly statistic difference between different gender and ages (P>0.05).Conclusion The angle of the movement for unilateral nasal transsphenoidal approach for pituitary surgery operation in the sagittal plane in the middle of the nasal meatus should be less than (11.22 ± 1.35)°,and the distance of the movement should be less than (16.71±2.07)mm. The angle of the movement in the plane through the tip of the nose and both ends of dorsum sellae should be less than (8.9 1 ± 1.1 9 )°, and the distance of the movement should be less than (14.23±2.09)mm.
