RESUMO
OBJECTIVE@#This study explored whether thyroglobulin and thyroid disease prevalence rates were higher in pregnant Chinese women with a median urinary iodine concentration of 100-149 µg/L, compared with those with a median urinary iodine concentration of 150-249 μg/L maintained through sustainable universal salt iodization.@*METHODS@#This was a cross-sectional study in which 812 healthy pregnant women were enrolled to collect samples of their household edible salt, urine, and blood during their routine antenatal care in the 18 counties in Fujian Province, China. The levels of salt iodine concentration, urinary iodine concentration (UIC), free triiodothyronine (FT3), free thyroid hormone (FT4), thyroid-stimulating hormone (TSH), thyroglobulin (Tg), thyroid peroxidase antibody and thyroglobulin antibody were assessed during the routine antenatal care visits.@*RESULTS@#The median UIC (mUIC) in pregnant women was 130.8 μg/L (interquartile range = 91.5-198.1 μg/L) in the counties with an mUIC of 100-149 μg/L (Group I), and 172.0 μg/L (interquartile range = 123.5-244.4 μg/L) in the counties with an mUIC of 150-249 μg/L (Group II). Goiter prevalence and thyroid nodule detection rates showed no difference between Group I and Group II ( P > 0.05). Except for FT4 values, the TSH, FT4, FT3, Tg and Tg values > 40 (μg/L) and the thyroid diseases prevalence rate (TDR) showed no significant differences between Group I and Group II ( P > 0.05), whether or not iodine supplementation measures were taken.@*CONCLUSION@#Compared with an mUIC of 150-249 μg/L, not only there was no difference in thyroid morphology, but also the Tg value, rate of Tg values > 40 µg/L, and TDR were not higher in pregnant women in the counties with an mUIC of 100-149 μg/L achieved through sustainable universal salt iodization in Fujian Province, China.

Animal survival necessitates adaptive behaviors in volatile environmental contexts. Virtual reality (VR) technology is instrumental to study the neural mechanisms underlying behaviors modulated by environmental context by simulating the real world with maximized control of contextual elements. Yet current VR tools for rodents have limited flexibility and performance (e.g., frame rate) for context-dependent cognitive research. Here, we describe a high-performance VR platform with which to study contextual behaviors immersed in editable virtual contexts. This platform was assembled from modular hardware and custom-written software with flexibility and upgradability. Using this platform, we trained mice to perform context-dependent cognitive tasks with rules ranging from discrimination to delayed-sample-to-match while recording from thousands of hippocampal place cells. By precise manipulations of context elements, we found that the context recognition was intact with partial context elements, but impaired by exchanges of context elements. Collectively, our work establishes a configurable VR platform with which to investigate context-dependent cognition with large-scale neural recording.

Objective:To explore the clinical efficacy of single-center infant kidney donor adult dual kidney transplantation to explore the difference of different operation methods and the operation options of different donor kidney conditions so as to improve the success rate of children kidney donor adult dual kidney transplantation and reduce complications.Methods:A total of 42 cases of infant and adult dual kidney transplantations at Department of Kidney Transplantation in The Second Xiangya Hospital of Central South University from December 2012 to May 2019 were divided into two groups according to whether or not donor kidney fulfilled the criteria of three " 5" . According to different surgical approaches, they were divided into three groups of A (classical En-Bloc operation), B (separated dual kidney transplantation) and C (modified operation). The clinical data and prognoses were analyzed.Results:The median follow-up period was 55(11-92) months. The estimated glomerular filtration rate was 123.4(92.2-156.6) ml/min for operation A, 97.2(81.3-116.6) ml/min for operation B and 133.9(133.9-133.9) ml/min for operation C. In donor group not fulfilling the " 5" principle, no thrombotic event occurred for operation A/C and 3 cases of transplantation for operation B. There were single renal embolism ( n=2) and dual renal embolism ( n=1)(3/5, 60%)( P<0.05). Urinary protein was positive in the last follow-up: operation A (1/2, 50%) and operation B (3/5, 60%) ( P<0.05). The estimated glomerular filtration rate at the last follow-up was 82.4(80.9-83.9) ml/min for operation A, 71.8(46.1-114.2) ml/min for operation B and 122(83.3-142.4) ml/min for operation C. The 1-year graft survival rate was 100% and 89.5% in three " 5" donor group and 3-year graft survival rate was 100% and 84.2% respectively. Conclusions:Satisfactory outcomes might be obtained during dual kidney transplantation for infants and adults. The incidence of thrombosis, urine leakage and urinary protein is lower in improved kidney transplantation group than that in previously operated group. The problem of graft hyperperfusion injury is well solved. And the long-term follow-up outcome is excellent.

RESUMO
OBJECTIVE: To study the miR-184 level in the seminal plasma exosome of male infertility patients and its clinical significance. METHODS: Between 2015 and 2019, we collected 285 seminal plasma samples from 97 azoospermia (AS) and 96 asthenospermia (AZS) patients and 92 age-matched normal fertile controls in Jiangsu Provincial Hospital of Traditional Chinese Medicine, General Hospital of Eastern Theater Command and the First Hospital Affiliated to Wenzhou Medical University, identified the isolated seminal plasma exosomes by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM) and Western blot, and detected the miR-184 level in the seminal plasma exosomes by quantitative real-time PCR (qRT-PCR). We determined the clinical value of the miR-184 level and its correlation with semen parameters by multiple statistics, predicted the target genes and involved pathways of miR-184 by bioinformatic algorithms, and analyzed their relationship with male infertility. RESULTS: NTA, TEM and Western blot exhibited plenty of exosomes in the seminal plasma of the patients. The results of qRT-PCR showed that the miR-184 level in the seminal plasma exosome was dramatically decreased in the AS patients compared with that in the normal fertile controls (0.227 ï¼»0.092, 0.790ï¼½ vs 0.650 ï¼»0.408, 1.061ï¼½, P < 0.01), but increased in AZS males in comparison with that in the control group (1.176 ï¼»0.661, 1.946ï¼½ vs 0.650 ï¼»0.408, 1.061ï¼½, P < 0.01). The areas under the ROC curve (AUC) for differentiating the AS and AZS patients from the controls were 0.866 (95% CI: 0.815ï¼0.916) and 0.724 (95% CI: 0.653ï¼0.795), respectively, and that for differentiating the AS from the AZS group was 0.964 (95% CI: 0.943ï¼0.985). The miR-184 level in the seminal plasma exosome of the AZS patients was correlated positively with the sperm count (r = 0.243, P = 0.017) but negatively with the percentage of progressively motile sperm (r = ï¼0.407, P = 0.006). Bioinformatics analysis indicated that the downstream target genes of miR-184 were significantly enriched in the protein regulatory pathways closely related to male reproduction and spermatogenesis. CONCLUSIONS: The miR-184 level in the seminal plasma exosome of infertility patients is significantly different from that of normal fertile males, which may serve as a potential auxiliary marker for the diagnosis of and participate in the development and progression of male infertility.

RESUMO
This study aimed to evaluate the clinical performance of p16/Ki-67 dual staining for triage high risk HPV (HR-HPV) infected women. Target objects were women who infected HR-HPV and received colposcopy examination between April and December of 2016 at the Second Affiliated Hospital of Zhengzhou University. Gynecologists collected the cervical exfoliated cells from eligible women for p16/Ki-67 dual staining, LBC testing and HPV DNA testing. Histology diagnosis were used as gold standard. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs) of p16/Ki-67 dual staining, LBC testing and HPV16/18 testing for triage of HR-HPV positive population were calculated and compared. A total of 295 HR-HPV infected women were selected, and the mean age was (44.29±11.48) years old. Positive rates of p16/Ki-67 dual staining, HPV16/18 testing and LBC testing were 70.17% (207), 56.95% (168) and 85.76% (253), respectively. When CIN2+as the endpoint, among the three triage methods, sensitivity of p16/Ki-67 dual staining was 90.00% (95: 85.06%-93.43%), higher than the value of HPV 16/18 testing, but lower than the value of LBC testing. Specificity, PPV and NPV of p16/Ki-67 dual staining were the highest [71.58% (95: 61.81%-79.67%), 86.96% (95:81.69%-90.88%) and 77.27% (95: 67.49%-84.78%)]. When detection for CIN3+, sensitivity of p16/Ki-67 dual staining was 92.90% (95: 87.74%-95.99%), lower than the value of LBC testing, but higher than the value of HPV16/18 testing. Specificity of p16/Ki-67 dual staining was 55.00% (95: 46.74%-63.00%), lower than the value of HPV16/18 testing, but higher than the value of LBC testing. PPV of p16/Ki-67 dual staining was 69.57% (95: 62.99%-75.43%), lower than the value of HPV 16/18 testing, but higher than the value of LBC testing. NPV of p16/Ki-67 dual staining was 87.50% (95: 78.99%-92.87%), higher than value of HPV 16/18 testing, but lower than the value of LBC testing. p16/Ki-67 dual staining has better clinical effects than HPV 16/18 testing and LBC testing for triage women with HR-HPV infection.
RESUMO
OBJECTIVE: To evaluate the effect of malaria vector control measures so as to provide the evidence for consolidating the control effectiveness of malaria and carrying out the vector surveillance in Suizhou City. METHODS: The distributions of Anopheles sinensis and An. anthropophagus were investigated by the combination of retrospective review and field survey. The changes of density and population of mosquito vectors were investigated and compared among various years. RESULTS: From 1985 to 1996, both An. sinensis and An. anthropophagus were found in 18 towns, and An. anthropophagus mosquitoes accounted for 52.3% of the total Anopheles mosquitoes. Only An. sinensis mosquitoes were found in other 26 towns. In 2003 and 2004, An. anthropophagus mosquitoes were found in the original 18 towns, and they accounted for 47.0% and 38.1% respectively, but in 2005, An. anthropophagus mosquitoes were not found in this city. However, the density of An. sinensis presented an upward trend. CONCLUSIONS: An. anthropophagus population has gradually disappeared in Suizhou City, and currently, An. sinensis is the main Anopheles population, which might be the malaria vector in suitable conditions. Therefore, the surveillance and control of Anophe les vector should be strengthened in order to consolidate the achievements of malaria elimination.

RESUMO
Objective To investigate health literacy and its influencing factors about the cancer prevention and control among urban residents in Guangxi. Methods Guangxi urban residents were selected by using multi-stage hierarchical cluster random sampling. Health Literacy resident cancer prevention and health literacy questionnaire, which was provided by National Urban Cancer Early Diagnosis and Treatment Project, were used for the face-to-face interview among participants. Results Among all the residents included in this study, 7.5 % had health literacy. Univariate analysis showed that gender, age, education, occupation, family income were influencing factors of health literacy(all P<0.05). The level of health literacy of female was higher than that of male. People aged 40-59 years old had the highest health literacy levels, while people aged 60 years old and above had the lowest health literacy levels. Business personnel and civil servant had higher health literacy levels than other professional staffs. The level of health literacy of residents with annual household income more than 8 ten thousand yuan was higher than that of other residents. Those with higher educational levels had better health literacy levels. Cancer prevention awareness and early detection, early diagnosis, early treatment awareness, two dimensions of cancer prevention and health literacy, was 57.2% and 17%, respectively. Logistic regression analysis indicated that gender, household income and occupation were independent factors influencing cancer prevention and health literacy in Guangxi urban residents. Conclusion The cancer prevention and health literacy levels of Guangxi urban residents are low and the development of cancer prevention awareness and early detection, early diagnosis, early treatment awareness is unbalanced. Gender, household income and profession are three independent factors influencing cancer prevention and health literacy.

RESUMO
BACKGROUND: In the clinic, 25%-35% heel pain is mostly caused by plantar fasciitis. Previous studies mainly focused on plantar fasciitis with heel pain caused by flat foot and the growth of calcaneus bone spur. There are no reports on other reasons for plantar fasciitis in large-sample studies. OBJECTIVE: Using the real-time shear wave elastography, CT scan and X-ray, the anatomic site and thickness of normal two-dimensional ultrasound standard flat plantar aponeurosis were identified to analyze the relationship between plantar elastic characteristics and plantar arch angle from non-weight-bearing to weight-bearing position so as to explore the correlation of plantar fasciitis with plantar elastics and plantar arch angle. METHODS: Fifty healthy volunteers (feet) were selected as the healthy control group. 100 cases of plantar fasciitis (one foot) were selected as the case group. Plantar arch angle from non-weight-bearing to weight-bearing position was obtained using X-ray and CT scan to identify anatomic site of plantar aponeurosis in both groups. Two-dimensional ultrasound and real-time shear wave elastography were utilized to obtain thickness and elastic modulus of plantar aponeurosis. RESULTS AND CONCLUSION: (1) From non-weight-bearing to weight-bearing, arch angle change value was (16.4±4.5)° in the healthy control group and (10.5±3.5)° in the case group. Significant differences in arch angle change were detected between the two groups (P <0.01). (2) Thickness of plantar fascia was obviously smaller in the healthy control group (2.4±0.3) mm than in the case group (3.5±0.9) mm. Elastic modulus of plantar fascia was obviously larger in the healthy control group (30.1±1.3) kPa than in the case group (9.1±1.2) kPa. Thickness of plantar fascia and elastic modulus of plantar fascia were significantly different between the two groups (P < 0.01). (3) In summary, real-time shear wave elastography combined with CT and X-ray images can investigate the morphological and elastic characteristics of the plantar aponeurosis from many aspects. Arch angle change is strongly associated with elastic modulus of plantar fascia. The decreased elastic modulus of plantar fascia is possibly one of the reasons for arch angle change from non-weight-bearing to weight-bearing conditions, and is probably one of reasons for plantar fasciitis with heel pain.
