ObjectiveTo observe clinical effectiveness and safety of lumbar oscillatory manipulation in the treatment of patients with lumbar disc herniation. MethodsThis study recruited 90 lumbar disc herniation patients who were randomly divided into 45 cases each in the treatment group and the control group. The treatment group was given lumbar oscillatory manipulation， while the control group was given traditional lumbar obliquely pulling manipulation， and both groups were treated twice a week for 4 weeks. The Oswestry dysfunction index （ODI） score， lumbar spine mobility， and the absolute values of difference in hardness between the left and right sides of the lumbar erector spinae muscle were compared between groups of patients before treatment and after 2 and 4 weeks of treatment； the shear wave elastic modulus of multifidus muscle and abdominal muscle thickness were compared between groups before treatment and after 4 weeks of treatment； the clinical effectiveness of the treatment was compared， and the safety evaluation was carried out. ResultsCompared with the group before treatment， the ODI scores and the the absolute values of difference in hardness between the left and right sides of the lumbar erector spinae muscle decreased after 2 and 4 weeks treatment in both groups， and the mobility of the lumbar vertebrae in all directions of anterior flexion， posterior extension， left lateral flexion， and right lateral flexion increased； the shear wave elastic modulus of bilateral multifidus muscles of the fourth lumbar vertebral segments decreased， and the thickness of abdominal muscle increased after 4 weeks of treatment in both groups （P＜0.05）. Compared with the control group， the ODI score of the treatment group decreased after 2 weeks of treatment， and the shear wave elastic modulus value of bilateral multifidus muscle of the fourth lumbar vertebral segment decreased and the thickness of abdominal muscle increased after 4 weeks of treatment （P＜0.05）. The total effective rate was 90.48% （38/42） in the treatment group and 71.43% （30/42） in the control group， and the clinical effectiveness of the treatment group was better than that of the control group （P＜0.05）. No adverse events occurred in both groups during the study. ConclusionLumbar oscillatory manipulation is superior to traditional lumbar obliquely pulling manipulation in relieving symptoms of lumbar disc herniation and improving lumbar spine function， which may be related to its improvement in the elasticity of the multifidus muscle.

ObjectiveTo investigate the association between estimated glucose disposal rate （eGDR） and the severity of coronary heart disease. MethodsWe conducted a hospital-based cross-sectional study that included 1258 patients （mean age： 62（53-68） years） who underwent coronary angiography for suspected coronary artery disease （53.9% were male）. Insulin resistance level （IR） was calculated according to eGDR formula： eGDR = 21.158 - （0.09 × WC） - （3.407 × hypertension） - （0.551 × HbA1c） ［hypertension （yes = 1 / no = 0）， HbA1c = HbA1c （%）］. Subjects were grouped according to the eGDR quantile. CAD severity was determined by the number of narrowed vessels： no-obstructive CAD group （all coronary stenosis were<50%， n=704）， Single-vessel CAD group （only one involved major coronary artery stenosis≥50%， n=205）， Multi-vessel CAD group （two or more involved major coronary arteries stenosis≥50%， n=349）； Multivariate logistic regression model was used to analyze the association between eGDR and CAD severity. The linear relationship between eGDR and CAD in the whole range of eGDR was analyzed using restricted cubic spline. Subgroup analyses were used to assess the association between eGDR and CAD severity in different diabetic states. Receiver operating characteristic （ROC） curve analysis were used to evaluate the value of eGDR in improving CAD recognition. ResultsA decrease in the eGDR index was significantly associated with an increased risk of CAD severity （OR： 2.79； 95%CI： 1.72~4.55； P<0.001）. In multivariate logistic regression models， individuals with the lowest quantile of eGDR （T1） were 2.79 times more likely to develop multi-vessel CAD than those with the highest quantile of eGDR （T3） （OR： 2.79； 95%CI： 1.72~4.55； P<0.001）. Multivariate restricted cubic spline analysis showed that eGDR was negatively associated with CAD and multi-vessel CAD （P-nonlinear>0.05）. In non-diabetic patients， compared with the reference group （T3）， the T1 group had a significantly increased risk of CAD （OR： 1.42； 95% CI： 1.00~2.01； P<0.05） and multi-vessel CAD （OR： 1.86； 95%CI： 1.21~2.86； P<0.05）. No statistical association was found between eGDR and CAD in diabetic patients. In ROC curve analysis， when eGDR was added to traditional model for CAD， significant improvements were observed in the model's recognition of CAD and multi-vessel CAD. ConclusionOur study shows eGDR levels are inversely associated with CAD and CAD severity. eGDR， as a non-insulin measure to assess IR， could be a valuable indicator of CAD severity for population.

Objective To explore the characteristics of white matter lesions(WMLs)causing cognitive function change in the patients with asymptomatic middle cerebral artery(MCA)stenosis,and to analyze the diagnostic efficiency of related indexes.Methods Thirty-nine patients diagnosed with asymptomatic MCA ste-nosis and presenting with WMLs in the department of neurology of the hospital from 2021 to 2022 were in-cluded as the observation group,and 34 healthy people were included as the control group.The two groups conducted the behavioral assessment of cognitive function,such as the Mini-Mental State Examination(MMSE),Montreal Cognitive Assessment(MoCA),Test of Connectivity Type A(TMT),Digit Symbol Test(SDMT),Digit Breadth Test(DST),Drawing the Clock Test(CDT),and Verbal Fluency Test(VFT).The receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficiency of related indica-tors.Results In the single cognitive function assessment scales,the scores of TMT in the observation group were significantly higher than those in the control group(P＜0.01),the scores of SDMT,DST,CDT and VFT in the observation group were significantly lower than those in the control group and the differences were sta-tistically significant(P＜0.01).In the comprehensive cognitive function assessment scales,the total scores of MMSE and MoCA in the observation group were significantly lower than those in the control group(P＜0.01).In the scores of each factor of the MMSE scale,the verbal ability in the observation group was signifi-cantly lower than that in the control group(P＜0.01),but the scores of orientation,memory,attention,calcu-lation and recall were had no statistically significant differences between the two groups(P＞0.05).In the scores of each factor of MoCA,the visuospatial and executive ability,delayed memory,attention and abstrac-tion ability in the observation group were significantly lower than those in the control group(P＜0.01),but the scores of naming ability,attention ability and orientation ability had no statistically difference(P＞0.05).The area under the ROC curve(AUC),sensitivity and specificity of MoCA and MMSE were 0.80,0.73,0.52,0.71,0.92 and 0.74 respectively.The efficiency of MoCA for diagnosing cognitive function disorders caused by asymptomatic MCA stenosis was higher.Conclusion Compared with single cognitive function assessment scale,the comprehensive cognitive function assessment scales could more comprehensively and accurately screen the cognitive function disorders caused by WMLs in the patients with asymptomatic MCA stenosis,in which the diagnostic efficiency of MoCA is the highest.

Objective Pertussis cases have increased markedly since 2018 in Guangxi.The aim of this study was to evaluate antibody levels and the infection status of pertussis in the resident population. Method A total of 10,215 serum samples from residents were collected from August-November 2018 and tested for anti-pertussis IgG and toxin IgG using the enzyme-linked immunosorbent assay(ELISA). Results Of the collected samples,1,833(17.94%)tested positive for anti-pertussis IgG,with the median concentration of 16.06 IU/mL.Antibody level<10 IU/mL accounted for more than 60%in children under 4 years of age,but declined with age,whereas the percentages of the other three levels(10-40,40-50,and≥50 IU/mL)increased almost with age(P<0.001).Moreover,7,924 samples were selected for anti-pertussis toxin IgG,of which 653(8.24%)tested positive(≥40 IU/mL)with the median concentration of 5.89 IU/mL,and 204 participants(2.56%)had recent pertussis infection(≥100 IU/mL).Among the different age groups,the highest rates of positivity and recent infection were observed at 11-20 years of age,the lowest positivity rate at 5 years of age,and the lowest recent infection rate at 4 years of age(P<0.001,P=0.005,respectively). Conclusion The survey results showed that all age groups in Guangxi lacked immunity against pertussis,which was one of the main factors contributing to the resurgence of pertussis in 2018.In addition,the prevalence of pertussis is relatively high in Guangxi,and its incidence is seriously underestimated,especially in adolescents and adults.

Ischemic stroke is a common neurological disorder that can lead to neuronal death and neurological dysfunction. Microglia is the main immune cells in the central nervous system, involved in post-stroke inflammation and tissue repair. Triggering receptor expressed on myeloid cells 2 (TREM2), a receptor expressed on the surface of microglia, plays a multifaceted role in neuronal survival and nerve repair after ischemic stroke, including promoting the phagocytosis of microglia, inhibiting excessive inflammatory response, maintaining the proliferation and survival of microglia, protecting neurons from damage, and promoting the recovery of nerve function. Therefore, elucidating the immunoregulatory mechanism of TREM2 on microglia after cerebral ischemia is of great significance for exploring new therapeutic directions for ischemic stroke.

Objective To explore the residual level of FPMs in indoor dust samples in Shenzhen from 2020 and 2021, and to analyze its temporal distribution characteristics. Methods In the present study, indoor dust samples (n=193) from residential buildings in Shenzhen. were collected to analyze the temporal variation characteristics of FPMs. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was applied to determine the concentrations of FP and its four major metabolites (fipronil-sulfone, fipronil-sulfide, fipronil-desulfinyl, and fipronil-amide; abbreviated as FP-SFO, FP-SFI, FP-DES, and FP-AM) in the samples. The sum of the concentrations of FP and its four metabolites was represented as additive mass concentration (ΣFPMs). Additionaly, Wilcoxon test was performed to determine the temporal distribution differences of FPMs’ concentrations. Results From 2020 to 2021, the concentration of ΣFPMs for the in door dust samples in Shenzhen ranged from 0.51 to 4 415 ng/g (median: 18.8ng/g). FP, FP-SFO AND FP-SFI were the major target analytes in the sample with detection rates of 90.60%，86.20% and 75.40%, respectively. The detection rates of other metabolites were low (≤ 44.3%). Analysis of the temporal variation trend of FPMs’ concentrations showed that there was no significant difference in the levels of ΣFPMs between warm season（spring and summer）and cold season（autumn and winter）in the indoor dust samples from 2020 to 2021(2.38 vs 2.84ng/g , P > 0.05). However , the concentrations of FP-SFI and ΣFPMs in the indoor dust samples collected from 2021 showed an significantly increasing trend compared with 2020（1.02 vs 1.89 , 17.80vs. 20.10 ng/g , P < 0.05). Conclusion From 2020 to 2021 , the detection level of FPMs in indoor dust in Shenzhen is relatively high and shows an upward trend , with no obvious seasonal difference. However, whether the residual level of FPMs in indoor dust poses a risk to human health needs further study.

Objective:To explore the application value of ultrasonic measurement of the pubic symphysis distance in predicting pubic symphysis diastasis(PSD) during delivery.Methods:A total of 262 pregnant women from June 2021 to July 2022 who delivered at Suzhou Wuzhong People′s Hospital and Jiangyin People′s Hospital were retrospectively analyzed. The patients were divided into PSD group of 26 cases and normal pregnant women group (control group) of 234 cases according to whether or not PSD was confirmed during postpartum follow-up. Relevant data of the two groups were collected, including the biparietal diameter and femoral length of the fetus within 7 days before delivery, the pubic symphysis distance of pregnant women when the cervix was not dilated, pubic symphysis distance when the cervix dilated to 5 cm during the first stage of delivery, and the pubic symphysis distance after delivery, the age of the pregnant woman, the gestational week, the number of pregnancies, and the birth weight of the fetus. The differences of the above relevant data between the two groups were compared.Spearman correlation analysis was used to analyze the correlation between various parameters. The occurrence of postpartum PSD, and Logistic regression was used to analyze the predictive value of various parameters on the occurrence of postpartum PSD. ROC curve was used to analyze the diagnostic efficacy of each parameters to predict PSD.Results:The fetal birth weight, number of pregnancies, pubic symphysis distance in three time points in the PSD group were significantly higher than those in the control group (all P<0.05). The age of the pregnant women was negatively correlated with the occurrence of postpartum PSD ( rs=-0.152, P=0.014). The fetal birth weight, the number of pregnancies, the pubic symphysis distance in the cervix no-dilated and the first stage of labor were positively correlated with the occurrence of postpartum PSD( rs=0.160, 0.166, 0.678, 0.581, all P<0.05). Logistic regression analysis showed that the increase of pubic symphysis distance before labor would increase the risk of postpartum PSD, and the difference was statistically significant ( OR=2 506.028, 95% CI=14.293-439 402.630, P=0.003). The increase of pubic symphysis distance at the first stage of labor increased the risk of postpartum PSD, with a statistically significant difference ( OR=10 704.027, 95% CI=33.830-3 386 803.429, P=0.002). The ROC curve analysis showed that the area under the curve of the pubic symphysis distance in the cervix no-dilated and the first stage of labor for the diagnosis of PSD were 0.896 and 0.917 respectively, the sensitivity were 0.731 and 0.885, the specificity were 0.940 and 0.829, and the corresponding critical values were 0.87 cm and 1.06 cm respectively. The area under the curve of the combination of the two parameters for the diagnosis of PSD was 0.930, the sensitivity was 0.885, and the specificity was 0.876. Conclusions:Ultrasonic measurement of pubic symphysis distance during delivery can predict the occurrence of postpartum PSD in pregnant women and can provide a basis for the occurrence and treatment of postpartum pubic symphysis separation in pregnant women.
