Objective To investigate the clinical value of thyroid globulin antibody(TgAb)and thyroid peroxidase antibody(TPOAb)in the diagnosis and treatment of papillary thyroid microcarcinoma(PTMC).Methods A total of 346 patients with thyroid nodules who underwent surgical treatment in the hospital from August 2012 to October 2021 were selected as the research objects.According to the postoperative pathologi-cal results,the patients were divided into the benign nodule group,PTMC group and non-micro papillary thy-roid carcinoma(PTC)group.The general data of the patients and thyroid function indexes[free triiodothyro-nine(FT3),free tetraiodothyronine(FT4),thyroid stimulating hormone(TSH),TgAb and TPOAb]before and after operation were collected,the tumor recurrence or lymph node metastasis after operation were ob-served,and the relationship between serum TgAb and TPOAb and the risk and prognosis of PTMC was ana-lyzed.Results The positivity rate of TgAb in the PTMC and non-micro PTC groups was significantly higher than that in the benign nodule group(P<0.05).The TPOAb positivity rate was not significantly different among the three groups(P>0.05).Only the TSH level in the PTMC group was higher than that in the non-micro PTC group(P<0.05).Multivariate logistic analysis showed that younger age,higher TSH and positive TgAb were independent risk factors for PTMC and non-micro PTC(P<0.05).However,the risk of PTC didn't increase with increasing TgAb titres.The positivity rate of TgAb in the PTMC and non-micro PTC groups didn't change significantly within one month after operation,but decreased in one year after operation(P<0.05).The TPOAb positivity rate decreased after operation,but the difference was not statistically sig-nificant(P>0.05).In the PTMC group,four cases had tumor recurrence or lymph node metastasis,and the TgAb level increased by 88.4%,49.5%,5.7%and 84.0%respectively when the tumor recurred or metasta-sized.Among them,the TPOAb level increased by 51.6%,30.0%and 2.9%respectively in three cases and decreased by 53.9%in one case.In the PTMC group,there were 11 patients with cervical lymph node enlarge-ment,and there was no statistical difference in TgAb and TPOAb levels when the condition changed(P>0.05).Conclusion TgAb is a risk factor for PTMC,and can be followed up regularly during the diagnosis and treatment of PTMC.The specificity of TPOAb is not as good as that of TgAb,and appropriate follow-up can be chosen during the course of the disease.

Acute cerebral infarction(ACI)has the characteristics of onset nasty and high mortality,and thus the rapid determination of the occurrence and development of ACI plays a key role in the diagnosis,treatment and prognosis of ACI patients.It has shown that the serum level of human haptoglobin(Hp)is related to ACI.In this study,surface enhanced Raman scattering(SERS)combined with immune recognition was applied to establish a quantitative analysis method for serum Hp.Firstly,the SERS substrate of silver nanoparticles was prepared on silicon wafer,and 4-mercaptobenzoic Acid(MBA)was used as a Raman probe by forming Ag—S bond and connecting it on the surface of nanoparticles.The carboxyl group of MBA was linked to amino group of self-made high-affinity antibody through forming CO—NH structure thus forming a SERS self-assembled chip of Hp(Ag/MBA/anti-Hp).Hp in serum could be specifically captured by antibodies on SERS substrate,which caused the shift of SERS characteristic peak of MBA.The results showed that there was a good linear relationship between the logarithm of Hp concentration and the SERS characteristic peak shift of MBA.The detection range was 1-1000 ng/mL(R2=0.988).The Hp concentrations in serum of 90 ACI patients were determined by this method,and the results were consistent with those of ELISA method,which proved the practicability and accuracy of this method.This method was highly specific,simple and convenient,which could realize the specific recognition and quantitative analysis of serum Hp,so as to be an effective means for clinical detection of serum Hp,thus providing a reference for the treatment and prognosis of ACI.

Objective:To explore the evaluation effect of ultrasonography and Pirani score on tarsal deformity, treatment effect and pseudo-correction of congenital clubfoot in infants and young children, and the correlation between the two methods.Methods:This is a retrospective case series study. The clinical data of 26 children (40 feet) with congenital clubfoot who were evaluated by ultrasonography in the Third Affiliated Hospital of Zhengzhou University from January 2020 to January 2023 were retrospectively collected. There were 16 males and 10 females. The age at the first ultrasound examination was ( M(IQR)) 9.0 (18.0) days (range: 1 to 46 days). All patients were treated with Ponseti method by the same physician. The Pirani scores before and after treatment and at the last examination, and the talonavicular angle, calcaneocuboid angle and tibiocalcaneal angle measured by ultrasound were collected, and the treatment and follow-up were recorded. Paired sample t test, repeated measures analysis of variance or Kruskal-Wallis test were used for data comparison, and Spearman correlation analysis was used for correlation analysis. The receiver operating characteristic curve was used to calculate the efficacy of ultrasound in evaluating different Pirani scores. Results:The number of plaster fixation in 26 children was 4.0 (1.0) times (range: 2 to 8 times). The medial talonavicular angle and posterior tibiocalcaneal angle were significantly improved after treatment and at the last follow-up compared with those before treatment, and the differences were statistically significant (all P<0.01). There was no difference in lateral calcaneocuboid angle before and after treatment and at the last follow-up ( F=1.971, P>0.05). Pseudo-correction occurred in 2 cases (2 feet) during the treatment, with an incidence of 5%. Correlation analysis showed that there was a moderate positive correlation between talonavicular angle and Pirani midfoot score ( r=0.480, P<0.01). There was no correlation between calcaneocuboid angle and Pirani midfoot score ( r=0.114, P=0.105). There was a moderate negative correlation between tibial heel angle and Pirani hindfoot score ( r=-0.566, P<0.01). The cut-off point of Pirani midfoot score of 1.5 was 38.78°, the sensitivity was 0.90, the specificity was 0.56, and the area under the curve was 0.75. The cut-off value of angle was 27.51 °, the sensitivity was 0.16, the specificity was 0.92, and the area under the curve was 0.44.The cut-off points of Pirani midfoot score of 3.0 were 45.08°and 9.96°, the sensitivity was 0.94 and 0.91, the specificity was 0.37 and 0.42, and the area under the curve was 0.59 and 0.62, respectively. The cut-off values of Pirani hindfoot score of 2.0 and 3.0 were 167.46° and 160.15°, respectively. The sensitivity was 0.75 and 0.67, the specificity was 0.81 and 0.83, and the area under the curve was 0.78 and 0.71, respectively. Conclusion:Ultrasound can complement with Pirani score, visually and dynamically observe the morphology and position changes of talonavicular joint, calcaneocuboid joint and tibiotalocalcaneal joint, monitor the recovery and pseudo-correction of tarsal bones, and better evaluate the therapeutic effect.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Health system performance and its influencing factors are measured from a subjective perspective in the context of high-quality development.Using data from the Chinese Social Survey from 2015 to 2021,this study constructed a health system performance index from the perspective of the sense of acquisition of the population and analyzed the change trends and influencing factors of China's health system performance through a multilayer regression model.The results showed that the comprehensive index of health system performance in China increased by 12.47%(β=6.143,P<0.01)from 41.732 in 2015 to 46.935 in 2021,of which the process index increased by 4.57%(β=2.391,P<0.01)from 43.961 to 45.968,and the outcome index increased from 48.501 to 58.009,an increase of 19.60%(β=11.504,P<0.01).Meanwhile,the sense of access to health system performance showed obvious heterogeneity,with factors such as gender,age,education,marital status,employment status,economic status,type of health insurance and type of area of residence significantly affecting the sense of access to health system performance of residents.The health system performance in China in the context of high-quality development has significantly improved,and the sense of access of residents has significantly increased.However,the improvement in the process dimension of the health system is relatively limited,and"difficult and expensive to see a doctor"remains serious.It's necessary to strength the health system performance of vulnerable groups,as well as rural areas.

Objective:To investigate the clinical value immature granulocyte percentage(IG％)and other inflammatory indicators in the severity of acute appendicitis.Methods:A total of 201 pediatric patients undergoing appendicitis surgery admitted to Zhoukou Central Hospital from June 2022 to August 2023 were included.Patients with pathologically confirmed actue appendici-tis were divided two subgroups:actue simple appendicitis(ASA)group and actue complicated ap-pendicitis(ACA)group,The variables that included IG％,white blood cell(WBC)count,absolute neutrophil count(ANC),absolute lymphocyte count(ALC),neutrophil to lymphocyte ratio(NLR),pro-calcitonin(PCT),C-reactive protein(CRP),platelet to lymphocyte(PLR)and other indexes were ana-lyzed between ASA and ACA group.The logistic regression model for diagnosis of ACA was es-tablished,and the diagostic value of this model and other inflammtory indicators for ACA was evaluated by receiver operating characteristic(ROC)curve analysis.Results:The levels of IG％,WBC,ANC,ALC,NLR,PCT and PLR were higher and the level of ALC was lower in ACA group than those in ASA group(all P＜0.05).Logistic regression analysis showed that IG％,NLR and CRP were three diagnostic determinants of ACA(all P＜0.05).The AUC of the established logistic model and IG％,NLR,CRP were 0.868,0.821,0.691 and 0.790(all P＜0.001).The logistic model was vali-dated by independent cohorts,and the AUC was 0.872,the sensitivity was 90.0％and the speci-ficity was 75.6％.Conlusions:The IG％value can early indicator for pediatric ACA,and the es-tablished logistic regression model based on biomarkers including IG％,NLR and CRP has clinical value in diagnosing ACA in children.

Objective:To evaluate the intervention effectiveness of acceptance and commitment therapy(ACT)for patients with depressive disorders.Methods:A computer search of the Web of Science Core Collection,Pubmed,EMBASE,Cochrane Library,PsycINFO,CNKI,WanFang and WeiPu full-text databases(until October 23,2023)was used to collect randomized controlled studies that used acceptance and commitment therapy for trea-ting patients with depressive disorders.Using Stata 17 software,meta-analysis was performed on the literature data that met the inclusion criteria.Results:After screening,11 studies remained for data extraction.The results of a ran-dom effects model indicated that ACT could significantly reduce depression levels in patients with depressive disor-ders(SMD=-1.22,95％CI:-2.05--0.40,P＜0.01),and had a certain maintenance effect(SMD=3.59,95％CI:1.57-5.62,P＜0.01).Conclusion:Acceptance and commitment therapymay could improve the level of depression in patients.

Objective:To evaluate the effect of dexmedetomidine-based anesthesia on cerebral oxygen saturation in the patients undergoing total laparoscopic hysterectomy.Methods:Fifty American Society of Anesthesiologists Physical Status classificationⅠorⅡpatients, aged 20-64 yr, undergoing elective total laparoscopic hysterectomy, were divided into 2 groups ( n=25 each) using a random number table method: conventional group (C group) and dexmedetomidine group (D group). Bilateral regoinal oxygen saturation (rSO 2) was monitored using a cerebral oxygen saturation monitor. In D group, dexmedetomidine was intravenously infused as a bolus of 0.5 μg/kg before anesthesia induction, and 10 min later dexmedetomidine was then given by an infusion of 0.5 μg·kg -1·h -1 until 30 min before the end of operation. The equal volume of normal saline was given instead in C group. The remaining anesthesia regimen was the same in two groups. The maximum (LrSO 2max, RrSO 2max) and minimum (LrSO 2min, RrSO 2min) of bilateral rSO 2 were recorded from entry to 2 min after induction (D 1), from >2 min after induction to completion of tracheal intubation (D 2), from completion of tracheal intubation to the end of skin incision (D 3), from skin incision to completion of pneumoperitoneum (D 4), from pneumoperitoneum to completion of Trendelenburg position (D 5), within 20 min of Trendelenburg position (D 6), >20-40 min of Trendelenburg position (D 7), >40-60 min of Trendelenburg position (D 8), and from >60 min of Trendelenburg position to 10 min after return to supine position (D 9). The occurrence of 60% baseline value 0.05). Compared with C group, the LrSO 2min, LrSO 2max, RrSO 2min, and RrSO 2max were significantly increased in D 4-D 8 periods in D group ( P<0.05). No bilateral rSO 2 <75% baseline value was found in group D. Conclusions:Dexmetomidine-based anesthesia can elevate intraoperative rSO 2 in the patients undergoing total laparoscopic hysterectomy.
