RESUMO
@#Objective To analyze the clinical efficacy and survival outcome of totally thoracoscopic redo mitral valve replacement and evaluate its efficiency and safety. Methods The clinical data of patients with totally thoracoscopic redo mitral valve replacement in Guangdong Provincial People’s Hospital between 2013 and 2019 were retrospectively analyzed. Survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were used to determine the risk factors for postoperative death. Results There were 48 patients including 29 females and 19 males with a median age of 53 (44, 66) years. All the procedures were performed successfully with no conversion to median sternotomy. A total of 15, 10 and 23 patients received surgeries under non-beating heart, beating heart and ventricular fibrillation, respectively. The in-hospital mortality rate was 6.25% (3/48), and the incidence of early postoperative complications was 18.75% (9/48). Thirty-five (72.92%) patients had their tracheal intubation removed within 24 hours after the operation. The 1- and 6-year survival rates were 89.50% (95%CI 81.30%-98.70%) and 82.90%(95%CI 71.50%-96.20%), respectively. Age>65 years was an independent risk factor for postoperative death (P=0.04). Conclusion Totally thoracoscopic redo mitral valve replacement is safe and reliable, with advantages of rapid recovery, reducing blood transfusion rate, reducing postoperative complications and acceptable long-term survival rate. It is worthy of being widely popularized in the clinic.
RESUMO
@#Objective To evaluate the efficacy of hybrid ablation through compared with thoracoscopic epicardial ablation. Methods In this study, 108 patients with all long-standing persistent atrial fibrillation (LSPAF) received thoracoscopic epicardial ablation (TEA) after enrollment. There were 82 males and 26 females at age of 56.5±9.4 years. After blanking-period, patients off antiarrhythmic therapy with sinus rhythm were divided into a hybrid ablation (HA) group (50 patients) and a TEA group (58 patients). Only patients in the HA group received catheter ablation after randomization subsequently. In at least two-year observation period, cardiovascular risk factors were observed in all groups’ patients. Results The mean follow-up duration was 17.3-41.8 (26.9±6.1) months and there was no significant difference between two groups [8.2-40.6 (27.5±5.7) months in the HA group and 17.3-41.8 (26.4±6.7) months in the TEA group]. The off antiarrhythmic agents (AADs) sinus rhythm rate was significantly higher in the HA group than that in the TEA group at the time of postoperative 6, 12, 24 and 36 months [96.0%, 90.0%, 83.7%, 83.7% versus 79.3%, 75.9%, 67.3%, 63.1%, HR=0.415 (95%CI 0.206-0.923)]. Conclusion We can conclude that the efficacy of two-staged hybrid ablation for LSPAF is superior to thoracoscopic epicardial ablation alone. Patients can obtain benefit from a supplemental radiofrequency catheter ablation after blanking-period of surgical ablation, instead of those without a supplemental ablation.

Based on the differences in the sensitivity and specificity of different biomarkers, exploration of the value of diverse biomarkers in the diagnosis and prognosis assessment of liver cancer can provide an important reference for clinicians to scientific and rational application of distinct biomarkers.
RESUMO
Objective:To establish and internally validate a visualized model for predicting the severity of acute pancreatitis (AP).Methods:From September 1st 2017 to August 31st 2020, 600 patients with AP diagnosed in the First Affiliated Hospital of Kunming Medical University were enrolled. According to the Atlanta classification of AP, the 600 patients were divided into severe acute pancreatitis (SAP) group (128 cases) and non-severe acute pancreatitis (NSAP) group (472 cases). The general clinical data (age, gender, body mass index, etc), laboratory indicators (fasting blood glucose, urea nitrogen, creatinine, etc.), complicated with ascites or pleural effusion, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores and bedside index of severity in acute pancreatitis (BISAP) score between the two groups were compared. The potential predictors of SAP were screened with least absolute shrinkage and selection operator (LASSO). The screened predictors were included in the multivariate logistic regression analysis to establish the logistic regression model. The operation characteristic curves of the model, APACHE Ⅱ scores and BISAP were drawn, the discriminative capability of the model was evaluated by comparing the area under the curve (AUC). Calibration, Hosmer-Lemesshow test and decision curve analysis (DCA) were used to evaluate the accuracy and clinical practicability of the prediction model. Bootstrap was used for internally validation of the model. Independent sample t test, Wilcoxon test and chi-square test were used for statistical analysis. Results:The difference of gender composition ratio between SAP and NSAP group was statistically significant ( χ2=4.092, P<0.05). The fatality rate of SAP group was higher than that of NSAP group(21.1%, 27/128 vs. 0, 0/472); the length of hospital stay of SAP group was longer than that of NSAP group((20.33±16.21) d vs. (8.42±4.26) d); the hospitalization cost, fasting blood glucose level, urea nitrogen level, creatinine level, C-reactive protein(CRP) level, D-dimer level, fibrinogen level, white blood cell count, percentage of neutrophils, neutrophil-lymphocyte ratio, APACHEⅡ and BISAP scores, the incidence of complicated with pleural effusion or ascites and the constituent ratio of alcoholic etiology of SAP group were all higher than those of NASP group (44 837.58 yuan (23 017.73 yuan, 102 579.77 yuan) vs. 12 301.46 yuan (8 649.26 yuan, 18 823.88 yuan); (10.48±4.84) mmol/L vs. (8.45±4.80) mmol/L; (8.80±6.50) mmol/L vs. (4.90±2.33) mmol/L; (139.56±127.75) mmol/L vs. (80.05±38.54) mmol/L; (187.33±87.25) mg/L vs. (90.81±82.53) mg/L; 5.19 mg/L (2.96 mg/L, 8.52 mg/L) vs.1.29 mg/L (0.53 mg/L, 2.87 mg/L); 6.13 mg/L (4.64 mg/L, 7.31 mg/L) vs. 4.58 mg/L (3.50 mg/L, 5.98 mg/L); (14.87±5.82)×10 9/L vs. (11.79±4.86)×10 9/L; 0.84±0.12 vs.0.78±0.12; 13.16±7.57 vs. 8.77±7.28; 9.80±6.09 vs. 3.79±2.59; 2.12±0.89 vs. 1.04±0.78; 65.6%, 84/128 vs. 12.9%, 61/472; 70.3%, 90/128 vs. 20.3%, 96/472; 18.8%, 24/128 vs. 11.4%, 54/472); serum albumin level, blood calcium level, and hematocrit level of SAP group were all lower than those of NSAP group ((30.86±4.95) g/L vs. (37.14±5.44) g/L; (1.98±0.31) mmol/L vs. (2.16±0.20) mmol/L; (42.40±8.67)% vs.(44.30±6.45)%), and the differences were all statistically significant ( χ2=99.403, t=8.235, Z=-13.330, t=4.239, 10.759, 5.207 and 11.227, Z=-11.406 and -6.234, t=6.097, 4.829, 6.011, 10.899 and 12.395, χ2=152.604, 117.563 and 4.757, t=-11.788, -6.180 and -2.310, all P<0.05). LASSO regression analysis screened out four predictors of CRP, urea nitrogen, D-dimer and ascites. The results of multivariate logistic regression analysis showed that CRP (odds ratio ( OR)=1.009, 95% (confidence interval) CI 1.006 to 1.012), urea nitrogen( OR=1.185, 95% CI 1.097 to 1.280), D-dimer( OR=1.166 95% CI 1.082 to 1.256), ascites ( OR= 4.848, 95% CI 2.829 to 8.307) were the independent predictors of SAP (all P<0.01). The AUC of the model (0.895 , 95% CI 0.865 to 0.926) was higher than those of the APACHE Ⅱ(AUC=0.835, 95% CI 0.791 to 0.878)and BISAP score (AUC=0.803, 95% CI 0.760 to 0.846), and the differences were statistically significant ( Z=2.578 and 4.466, both P<0.05). The results predicted by the model in the calibration chart and the Hosmer-Lemesshow test were highly consistent with the results of actual clinical observation. When the probability of SAP in the model was 10% to 95%, the DCA curve of the model was higher than the two extreme lines, which had certain clinical practical value. After bootstrap internal validation, the model had a high discrimination ability (AUC=0.892), and its predicted AP severity curve was still in good agreement with the actual clinical AP severity curve. Conclusion:The prediction model established based on CRP, urea nitrogen, D-dimer and ascites can predict the severity of AP, and help doctors to make more scientific clinical decision.
RESUMO
Objective:To observe the dynamic changes of thyroid hormone levels and thyroid autoimmune antibodies in pregnant women in Xinjiang Uygur Autonomous Region during pregnancy, and to investigate the significance of repeated screening of thyroid function in different gestational ages.Methods:A retrospective study was carried out of pregnant women who completed thyroid function screening in Clinic, People's Hospital of Xinjiang Uygur Autonomous Region from January 2015 to December 2017, and the test results of thyroid stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), thyroid peroxidase antibody (TPOAb), and anti-thyroglobulin antibody (TGAb) were collected and analyzed of their changes during pregnancy. Pregnant women were divided into 2 different gestational age groups by the age limit of 30, the changes of thyroid dysfunction rate with pregnancy were analyzed, and the clinical significance of repeated screening in different pregnancy stages was discussed. Results:Changes of thyroid-related indicators with pregnancy: first, second, and third trimesters were 404,725, and 767 cases, respectively; TSH level in the third trimester (2.76 mU/L) was significantly higher than those in the first and second trimesters (2.55, 2.36 mU/L, P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the FT 4 and FT 3 levels decreased gradually with pregnancy ( P < 0.05); the positive rate of TPOAb was significantly higher in the first and second trimesters than that in the third trimester ( P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the positive rate of TGAb decreased gradually with pregnancy ( P < 0.05). Comparison of abnormal rate of TSH in different gestational ages: the first, second, and third trimesters were 352, 664, 735 cases, respectively; the abnormal rate of TSH in the overall study was statistically significant at different stages of pregnancy (χ 2=31.627, P < 0.05), the first trimester was significantly higher those in the second and third trimesters ( P < 0.05). In pregnant women aged ≥30 years old, the abnormal rate of TSH in the first trimester was significantly higher than those in the second and third trimesters ( P < 0.05); in pregnant women aged < 30 years old, the abnormal rate of TSH in the first trimester was significantly higher than that in the third trimester ( P < 0.05). There were no significant differences in the abnormal rate of TSH in the first, second, and third trimesters between the < 30 years old group and ≥30 years old group ( P > 0.05). Comparison of abnormal rate of FT 4 in different gestational ages: there were no significant differences in the FT 4 abnormal rate among different pregnancy groups in the overall, < 30, ≥30 years old groups (P > 0.05). In early pregnancy, the abnormal rate of FT 4 in the ≥30 years old group was higher than that in the < 30 years old group ( P < 0.05); in second and third trimesters, there were no significant differences between the two age groups ( P > 0.05). Conclusions:Screening for thyroid function in the first trimester of pregnancy is important for women of different ages. Except for women with abnormal thyroid function who have not been treated during the first trimester, the rest may not need to be screened again. Pregnant women aged ≥30 years old may have a higher risk of thyroid dysfunction than those < 30 years old.
RESUMO
Objective To establish a reference range for specific thyroid function during pregnancy and to explore the influencing factors of hypothyroxinemia during pregnancy.Methods A retrospective analysis of 2 996 cases of thyroid function in the pregnant women who were with single pregnancy and without thyroid diseases and family history of those diseases.Results (1) Establish a unified reference range for specific thyroid function during pregnancy;the early,middle,and late trimesters thyrotropin (TSH) ranges were 0.02-6.39,0.16-6.23,0.64-6.59 mU/L,respectively,while free thyroxine (FT4) ranges were 11.32-23.00,9.39-18.92,8.54-16.73 pmol/L respectively.The specific reference ranges of Han and Uygur pregnant women were established separately.There was no difference in the detection rates of various thyroid diseases when using their respective reference ranges and the unified reference range of the hospital (P > 0.05).(2) The detection rate of various thyroid diseases (except subclinical hyperthyroidism) of our subjects with China guideline reference range was significantly higher than the reference range with the hospital (P<0.05).(3) The detection rates of hypothyroxinemia in all pregnant women with FT4 cut points of P2.5 and P5 were 4.3% and 7.4%,respectively,of which the Han population was 4.3% and 7.1%,respectively,and the Uygur population was 4.3% and 7.9%,respectively.(4) Comparing the mean age,gestational age,median urine iodine,and thyroid antibody positive rate between the hypothyroxinemia group and the control group,only the mean age and gestational age were different (P<0.05);Logistic binary regression analysis showed that age was the risk factor for hypothyroxinemia during pregnancy (OR =1.035,95% CI 1.006-1.066,P < 0.05).Conclusions The Han and Uygur pregnant women in this area both can use the thyroid reference range of our hospital during pregnancy.The establishment of thyroid reference range may avoid over-diagnosis of thyroid disease during pregnancy.Age is a possible influencing factor of hypothyroxinemia during pregnancy.
RESUMO
OBJECTIVE@#To study the effects of myo-inositol and luteolin on human lung cancer A549 cells and explore the possible mechanisms.@*METHODS@#A549 cells were treated with different concentrations of myo-inositol and luteolin, either alone or in combination, and the cell viability was examined using MTT assay. A549 cells and human bronchial epithelial Beas-2B cells were treated for 48 h with 10 mmol/L myo-inositol and 20 μmol/L luteolin, alone or in combination, and the cell proliferation was detected using MTT assay; the colony formation and migration of the cells were examined with colony formation assay and wound healing assay, respectively. The protein expression levels in A549 cells were detected using Western blotting.@*RESULTS@#Both myo-inositol and luteolin could dose-dependently inhibit the viability of A549 cells. Treatments with 10 mmol/L myo-inositol, 20 μmol/L luteolin, and both for 48 h caused significant reduction in the cell viability (92%, 83% and 70% of the control level, respectively) and colony number (79%, 73% and 43%, respectively), and significantly lowered the wound closure rate (24.61%, 13.08% and 8.65%, respectively, as compared with 29.99% in the control group). Similar treatments with myoinositol and luteolin alone or in combination produced no significant inhibitory effect on the growth, colony formation or migration of Beas-2B cells. The expressions of p-PDK1 and p-Akt in myo-inositol-treated A549 cells and the expression of pPDK1 in luteolin-treated cells were significantly decreased ( < 0.05), and the decrements were more obvious in the combined treatment group ( < 0.05).@*CONCLUSIONS@#Luteolin combined with myo-inositol can selectively inhibit the proliferation and migration of A549 cells, and these effects are probably mediated, at least in part, by suppressing the activation of PDK1 and Akt.

Basic clinical data, serum TSH, thyroid peroxidase autoantibody (TPOAb), and urine iodine levels were retrospectively analyzed. Results (1) General results:The median urine iodine level was 162.6μg/L(53.4-539.3μg/L), and the distribution of urine iodine classification was iodine deficiency 42.9%(672/1568), iodine appropriate 36.7%(576/1568), iodine slightly high 17.1%(268/1568)and iodine excess 3.3%(52/1568)respectively.(2)The median urine iodine levels of Han and Uygur pregnant women were 169.1μg/L(54.6-583.4μg/L)and 156.3μg/L (53.1-539.3μg/L)respectively, and the difference was statistically significant(P<0.05).The distribution of urine iodine status in pregnancy between Han and Uygur was significantly different, which were 40.9%(391/956)vs. 45.9%(281/612)in iodine deficiency, 35.4%(338/956)vs. 38.9%(238/612)in iodine appropriate, 20.2%(193/956) vs. 12.3%(75/612) in iodine slightly high and 3.6%(34/956) vs. 2.9%(18/612)in iodine excess.(3)High serum TSH level proportion was significantly higher in Uygur ethnic group, early pregnancy, thyroid peroxidase antibody positive and anti-thyroglobulin antibody positive group when compared with Han, late pregnancy, thyroid peroxidase antibody negative and anti-thyroglobulin antibody negative groups (all P<0.05). There were no significant differences in different age groups and iodine nutrition groups(P>0.05).(4)There was no correlation between urinary iodine and TSH levels in all pregnant women(P>0.05),neither in Han or Uygur group. When further stratified by gestational age, age, and antibody level, there was a positive correlation between urine iodine and serum TSH level in Han pregnant women>30 years old(P<0.05), and there was a negative correlation in the third trimester in Uygur (P<0.05). When serum antibody level, gestational week and age were controlled. There was no correlation between urine iodine and serum TSH level in neither group. Conclusions (1)In Han and Uygur pregnant women, the median urine iodine level and the distribution of urine iodine classification between two ethnic groups are significantly different.(2)The correlation between urine iodine and serum TSH is not identified in Han or Uygur pregnant women.
RESUMO
Objective To explore the potential correlation between fluoride levels of urine and influencing factors in water-high-fluoride areas.Methods In 2010,based on plain area,mountainous area and mixed area (altitudes were 898,2 200,1 460 m,respectively),3 villages of water-high-fluoride areas were selected by purpose sampling;pupils' family members were selected as survey population by cluster sampling.Questionnaire was conducted to collect general information;fluoride contents in urine and drinking water were measured using ionselective electrode.A linear multiple regression was used to examine which factors affected urinary fluoride.Results Totally there were 968 people distributed in plain area (444),mixed area (368) and mountainous area (156),medians of urinary fluoride level were 0.71,1.59 and 1.67 mg/L,respectively,the difference was significant (F =203.90,P <0.01);medians of water fluoride level in the three different habitats were 0.50,1.00 and 3.50 mg/L,respectively,the difference was significant (F =331.98,P < 0.01).Age,gender,fluoride contents in drinking waters and habitat explained 33.1% of urinary fluoride variation.Male had higher urine fluoride than female,older age and higher level fluoride in drinking water contributed to higher fluoride level in urine,higher altitude contributed to higher urinary fluoride.Conclusion Once fluoride content in urine is used to estimate fluoride exposure level among people in high fluoride area,gender and age must be taken in consideration.
