Objective To compare the clinical values of impedance method,optical method and microscopy when used to detect platelet abnormal results.Methods Platelet re-examinations by optical method and microscopy were carried out in case of low confidence degree in platelet test with impedance method by XE-2100 automatic hematology analyzer,and then the results by the three methods were compared.Results Most of the low-confidence-degree results by impedance method could be corrected by re-examination by optical method,and the remained had to turn to microscopy due to unsatisfied requirements of the instrument.Conclusion Optical method has to be involved to correct the platelet abnormal results by XE2100 automatic hematology analyzer,and microscopy should be applied in case optical method doesn't work.The three methods gains advantages and disadvantages of themselves,and can be supplementaries for one another.

Objective:To investigate the effect of gold microneedle and subcutaneous apocrine excision in the treatment of bromidrosis and the occurrence of postoperative complications.Methods:From July 2019 to November 2020, 42 patients (13 males and 29 females; 16-47 years old, average 23 years old) were treated with plastic surgery in the First Affiliated Hospital of Xinjiang Medical University, 20 patients received gold microneedle treatment, and 22 patients received minimally invasive surgery (subcutaneous apocrine excision surgery). The patients were followed up for 3-6 months after operation, and the severity of preoperative bromidrosis, postoperative curative effect and occurrence of postoperative complications were compared between the two groups.Results:Eighteen cases were effective in the gold microneedle group, accounting for 90%; 22 cases were effective in the minimally invasive surgery group, accounting for 100%; the difference between the two groups was statistically significant ( P<0.05). There was a negative correlation between the grade of bromidrosis before operation and the curative effect after operation in the gold microneedle group, and the correlation coefficient was not statistically significant in the minimally invasive operation group ( P>0.05). Complications occurred in 4 cases in the gold microneedle group, accounting for 20.0%; 10 cases presented with complications in the minimally invasive surgery group, accounting for 45.5%; the difference was statistically significant ( P<0.05). Conclusions:The therapeutic effect of gold microneedle is lower than that of minimally invasive surgery, and the higher the degree of bromidrosis, the worse the curative effect. The postoperative complication rate of gold microneedle treatment for bromidrosis is lower than that of minimally invasive surgery.

Objective To investigate the associations between thyroid hormone sensitivity indices in euthyroid patients with hypertension and the risk of ischemic stroke,as well as gender difference in this association.Methods We selected 760 hypertensive patients admitted to the Geriatric Neurology Department and outpatient clinic in The Second Affiliated Hospital of Xi'an Jiaotong University between April 2021 and May 2022.We collected their basic characteristics,blood biochemical parameters,thyroid indices,and brain magnetic resonance imaging information.All the patients were divided into two groups based on the clinical manifestations and brain magnetic resonance imaging:hypertension combined with ischemic stroke(n=526)and control(n=234)groups.Independent sample t-tests or non-parametric tests were used to compare the differences in thyroid hormone sensitivity indicators between the two groups.Spearman correlation analysis was used to analyze the correlation between serum thyroid indices and ischemic stroke.Multivariate conditional Logistic regression analysis was made to estimate odds ratios(ORs)and 95％confidence intervals(CIs)for thyroid indices and ischemic stroke.Results There were statistically significant differences between the two groups in terms of age,gender,TC,LDL-c,HDL-c,systolic blood pressure,FT3/FT4,TFQI,and PTFQI(all P＜0.05).However,there was no statistically significant difference between the two groups in weight,smoking,drinking,history of diabetes,TG,FBG,diastolic blood pressure,TSHI,or TT4RI(all P＞0.05).The results of Spearman correlation analysis showed a negative correlation between FT3/FT4 and ischemic stroke(P＜0.05),but a positive correlation of TFQI and PTFQI with ischemic stroke(P＜0.05)in euthyroid patients with hypertension.Logistic regression analysis showed that FT3/FT4 was significantly associated with ischemic stroke in euthyroid patients with hypertension(P=0.001),with OR(95％CI)of 0.001(0.000,0.058).After stratifying by gender,Logistic regression analysis found that FT3/FT4,TFQI,and PTFQI were associated with an increased risk of ischemic stroke in female patients,with OR(95％CI)of 0.000(0.000,0.001),3.132(1.415,6.930),and 3.010(1.406,6.445),respectively.Conclusion Lower serum FT3/FT4 ratio is associated with an increased risk of ischemic stroke in euthyroid patients with hypertension,and the significant association of TFQI and PTFQI with the risk of ischemic stroke is found in females.

【Objective】 To investigate the association between remnant cholesterol (RC) and triglyceride and glucose (TyG) index in young and middle-aged patients with ischemic stroke. 【Methods】 A total of 268 patients were divided into two groups, namely low TyG index group (n=134) and high TyG index group (n=134). Characteristics of the study population and metabolism risk factors (TC, TG, HDL-C, LDL-C, UA) were collected from biochemical test results. Spearman correlation analysis was used to analyze the correlation between metabolism risk factors and TyG index. Multivariate conditional logistic regression analyses were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for RC and TyG index. 【Results】 Compared with the low TyG index group, significant differences were observed for BMI, history of diabetes, history of hypertension, SBP, DBP, FBG, TC, TG, LDL-C, RC, UA, and TyG index in high TyG index group. No significant differences were observed in age, gender, smoking status, or drinking status, HDL-C between the two groups. Spearman correlation analysis indicated that significant linear associations were observed between BMI, SBP, DBP, FBG, TC, TG, HDL-C, LDL-C, RC, UA and TyG index. Logistic regression analysis revealed that the RC, BMI, hypertension, diabetes, TC, LDL-C, and UA were significantly associated with the risk of increased level of TyG index. After adjusted analysis by RC, BMI, hypertension, diabetes, TC, LDL-C, and UA, only RC was significantly associated with an increased risk of increased level of TyG index. 【Conclusion】 Remnant cholesterol was associated with an increased risk of elevated TyG index level in young and middle-aged patients with ischemic stroke.

【Objective】 To investigate the association of thyroid indices with the prevalence of ischemic stroke in young and middle-aged euthyroid population. 【Methods】 For this retrospective study, 620 euthyroid patients aged from 18 to 65 years were divided into ischemic stroke group (n=308) and non-ischemic stroke group (n=312). The characteristics of the study population; serum thyroid indices, i.e., free triiodothyronine (FT3), free thyroxine (FT4) and thyroid-stimulating hormone (TSH), were collected from biochemical test results. Multivariate conditional logistic regression analyses were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for thyroid indices and ischemic stroke. 【Results】 Compared with non-ischemic stroke group, significant differences were observed in age, gender, weight, smoking status, drinking status, history of hypertension and diabetes, SBP, DBP, FBG, TC, HDL-C, LDL-C, FT3, FT4, FT3/FT4, TFQI, and PTFQI in ischemic stroke patients (all P<0.05). No significant differences were observed for TG, TSH, TSHI, or TT4RI between the two groups (all P>0.05). Logistic regression analysis revealed that lower FT3 [OR (95% CI) =0.722 (0.547~0.955) , P=0.022] and FT3/FT4 ratio [OR (95% CI) =0.723 (0.600~0.870) , P=0.001] , FT4 [OR (95% CI) =1.099 (1.011~1.194) , P=0.026] were significantly associated with an increased risk of ischemic stroke. After stratified analysis by hypertension, FT4 [OR (95% CI) =1.133 (1.021~1.257) , P=0.019] , lower FT3/FT4 ratio [OR (95% CI) =0.723 (0.600~0.870) , P=0.003] , TFQI [ OR (95% CI) =1.854 (1.026~3.350) , P=0.041] , and PTFQI [OR (95% CI) =1.871 (1.065~3.288) , P=0.029] were significantly associated with an increased risk of ischemic stroke in patients combined with hypertension, while after stratified analysis by diabetes, we only found that lower FT3/FT4 ratio [OR (95% CI) =0.730 (0.559~0.953) , 0.704 (0.536~0.944) , P=0.021] and FT4 [OR (95% CI) =1.170 (1.025~1.335) , P=0.026] were significantly associated with an increased risk of ischemic stroke in patients combined with diabetes. 【Conclusion】 FT3, FT4, and FT3/FT4 ratio are associated with an increased risk for ischemic stroke in young and middle-aged euthyroid population; TFQI and PTFQ are associated with an increased risk for ischemic stroke in patients combined with hypertension.
