ObjectiveTo explore the clinical and pathological features of Hainan patients with thyroid carcinoma treated in Hainan Provincial People' s Hospital.Methods A total of 239 clinical cases of Hainan patients with thyroid carcinoma treated in Hainan Provincial People' s Hospital from 2006 to 2010 were retrospectively analyzed.Results The number of thyroid carcinoma cases between 2006 to 2008 was stable.But the cases in 2009 were 72.97％ higher than that in 2008.Female' s peak of onset age was 25 to 55 years and male was 20 to 55 years.The cases of Hant were 231 (96.65％) and the national minority were 8(3.35％ ).So ethnic composition ratio between cases and local population has a very significant difference (x2 =21.376,P ＜0.01 ).The eastern and western regions had 175 cases and 64 cases respectively,138 (78.86％) and 34(46.88％ ) cases from city respectively.Urban and rural ratio between eastern and western areas had a significant difference (x2 =4.420,P ＜ 0.05 ).The 239 cases were composed of 228 cases (95.4％) of papilarry thyroid carcinoma,7 cases (2.92％) of medullary thyroid carcinoma,both 2 cases (0.84％) of follicular thyroid carcinoma and anaplastic thyroid carcinoma.Conclusions The incidence of Hainan nationality patients with thyroid carcinoma treated in Hainan Provincial People' s Hospital has increased from 2006 to 2010,with younger trend and regional difference.Thyroid carcinoma has a difference in race and region.The rank of the rate of pathological type is papillary thyroid carcinoma,medullary thyroid carcinoma,follicular thyroid carcinoma,undifferentated thyroid carcinoma in order.

Objectives To investigate the expression and differential diagnosis value of Galectin-3 and Cyclin D1 in benign and malignant thyroid mass.Methods The expression of Galectin-3 and Cyclin D1 protein in 31 cases of nodular goiter(group A),65 cases of papillary thyroid carcinoma(PTC,group B) and 10 cases of normal thyroid tissues(group C,the control group)was detected by SP immunohistochemical method.The clinical data were analyzed.Results The expression level of Galectin-3 in group B was 83.03％ (54/65),significantly higher than that in group A(19.35％,6/31) and group C(0％).The difference of group A and group B in terms of the expression level of Galectin-3 protein had statistical significance(x2 =36.360,P ＜0.05).The expression level of Cyclin D1 protein in group B was 72.30％ (47/65),significantly higher than that in group A(12.90％,4/31)and group C(0％).The difference of group A and group B in terms of the expression level of Cyclin D1 protein had statistical significance(x2 =29.740,P ＜ 0.05).The combination detection of the positive expression of Galectin-3 and Cyclin D1 in benign and malignant thyroid mass showed that the difference between group A and group B had statistical significance(P ＜ 0.01).The expression of Galectin-3 and Cyclin D1 was positively correlated in group B(R =0.509,P ＜0.05).The positive expression rate of Cyclin D1 protein was 90％ (18/20) and 64.44％ (29/45)respectively in PTC patients with lymph node metastasis and without lymph node metastasis.The difference had statistical significance (P ＜ 0.05).Conclusions The expression of Galectin-3 and Cyclin D1 is positively correlated in PTC and the expression of the 2 proteins in PTC is higher than that in nodular goiter and normal thyroid tissues,indicating that the 2 proteins can be used as valuable markers for patients with thyroid carcinoma.Combined detection of Cyclin D1 and Galectin-3 protein in thyroid tissues is useful for the diagnosis of thyroid cancer.

ObjectiveTo explore the effects of body weight and waist circumference on static and dynamic balance function in overweight and obese adults. MethodsParticipants （n=103） were selected by cluster random sampling from the Hypoglycemic Weight Loss Clinic of the Endocrinology Department of the Third Affiliated Hospital of Sun Yat-sen University. All participants were assessed for basic data collection， biochemical test， body weight， waist circumference and height measurement， static balance function assessed by balance error scoring system （BESS） and dynamic balance function assessed by functional reach test （FRT）. The BESS score and FRT distance of all participants were compared among groups according to different BMI grades and WC grades. Multivariate linear regression was used to analyze the influencing factors of participants' dynamic and static balance functions. Results① With the increase of BMI grading， the BESS score showed an upward trend， and the difference between groups was statistically significant （P = 0.004）. The BESS score of normal WC patients was lower than that of central obesity patients （P < 0.001）， which indicated that compared with normal BMI， overweight and obese people had poor dynamic and static balance ability； ② With the BMI grading， the FRT distance increased， showing a downward trend （P < 0.001）. The FRT distance in normal WC patients was significantly higher than that in central obesity patients （P < 0.001）， which indicated that the static and dynamic balance ability of central obesity patients was worse than that of normal WC patients； ③ In BMI overweight group， the FRT distance decreased significantly with the increase of WC （P = 0.02）. The results showed that under the condition of no difference in BMI， Compared with normal WC， the dynamic and static balance ability of central obese patients was worse； ④ The influence of BESS score on BMI（B=4.12，P =0.027， 95% CI=0.48-7.75）and WC（B = 3.47，P = 0.046， 95% CI = 0.07 - 6.88）was significant. The influence of FRT distance on BMI（B = -5.68，P = 0.001， 95% CI = -8.95 - 2.41）and WC（B = -4.71，P = 0.003， 95% CI = -7.83 to -1.61）was significant， which indicated that the static and dynamic balance ability of obese people was worse with the increase of BMI， and the ability of dynamic and static balance of central obesity was worse than that of normal WC. ConclusionWaist circumference is an independent factor affecting the dynamic and static balance function of overweight and obese people. Under similar BMI， the dynamic balance function of central obese people is worse than that of people with normal waist circumference， leading to higher risk of falling.

【Objective】 To investigate the detection of pathogenic microorganisms in umbilical cord blood and maternal blood from 2012 to 2021, so as to improve the collection of umbilical cord blood and guarantee the safety of umbilical cord blood hematopoietic stem cells (HSC) . 【Methods】 Detection results of pathogenic microorganisms of umbilical cord blood and maternal blood among 64 077 cases from Tianjin Cord Blood Bank from 2012 to 2021 were retrospectively analyzed. 【Results】 A total of, 2 072 cases (3.23%) were detected positive, among which, 184 cases (0.29%) were positive for aerobic bacteria culture, 1 504 cases (2.34%) were positive for anaerobic bacteria culture, and 384 cases (0.60%) were positive for both aerobic and anaerobic bacteria culture. From 2012 to 2021,the overall positive rate showed a downward trend, with a difference in the positive rate between each year (P<0.05). The positive rate of anaerobic bacteria was higher than that of aerobic bacteria and that of anaerobic and aerobic bacteria (P<0.05). After Gram staining, the microscopic detection rate of bacterial positive samples was highest in G^- bacilli, followed by G⁺ bacilli, G⁺ cocci, G^- cocci and others. Among the 64 077 cases, 169 cases (0.26%) showed reactivity in cord blood tests and 1 231 cases (1.92%) showed reactivity in maternal blood tests. Umbilical cord blood and maternal blood HIV-Ag/Ab tests showed reactivity after initial screening. After confirmation by Western blotting, there was 1 case of uncertain maternal blood, while the rest were negative. The reactive rates of anti-TP (0.12%) and anti- HCV (0.11%) in umbilical cord blood were higher than those of HBsAg (0.03%) and CMV-IgM (1/64 077).There was a difference in the reactive rate of anti-TP detection in umbilical cord blood between different years (P<0.05),while there was no statistically significant difference in that of HBsAg, anti-HCV and CMV-IgM (P> 0.05).The reactive rate of HBsAg in maternal blood (1.38%) was higher than that of CMV-IgM(0.29%) , anti-TP(0.13%) and anti-HCV (0.12%) . There were differences in the reactive rates of HBsAg, anti-HCV ,and anti-TP in maternal blood among different years (P<0.05),and that of HBsAg showed a decreasing trend, while the reactive rate of CMV-IgM was not statistically significant (P>0.05). The reactive rates of HBsAg and CMV-IgM detected in maternal blood were significantly higher than those in umbilical cord blood (P<0.05) . The reactive rates of anti-HCV and anti-TP in maternal blood were consistent with those in umbilical cord blood (P>0.05). 【Conclusion】 The reactive rates of anti-HIV and CMV-IgM in cord blood, and that of anti-HIV in maternal blood are low, but those of anti-TP and anti-HCV in cord blood are relatively high. The reactive rate of HBsAg is high in maternal blood,but with a downward trend,but low in umbilical cord blood due to maternal-infantile transmission blocking. The detection of transfusion transmitted pathogens and bacteria plays a critical role on the safety of umbilical cord blood HSCs. Effective detection of transfusion transmitted pathogens and culture of bacteria are the key to ensure the quality of umbilical cord blood, which can improve the safety of umbilical cord blood HSCs transplantation.
