Objective To study the inhibitory effects of circular dumbbell decoy oligodeoxynucleotides targeting NF-?B on TNF-? expression in cortical neurons under the oxygen glucose deprivation/reoxygenation(OGD/R).Methods The cultured neurons dissociated from the cortex of neonatal rats were observed on the 7th day after culture.To make the ischemia/reperfusion model in vitro,the neurons were exposed to OGD 4 h before cultured in normal culture media.The neurons were divided into 5 groups according to different processing methods 2 h before exposure to OGD,including normal group,OGD4 h/R6 h treated,NF-?B decoy ODNs treated,scrambled decoy ODNs treated and TransfastFastTM Transfection Reagent treated groups.The protein level of NF-?B P65 in primary neurons was detected by Western blotting.The protein and mRNA levels of TNF-? were detected by immunocytochemical method and RT-PCR,respectively.Results NF-?B decoy ODNs could effectively inhibit the expression levels of NF-?B P65 protein,TNF-? mRNA and protein in neurons(P

Objective To investigate the effect of electrical stimulation to cerebellar fastigial nucleus on expression of nuclear factor-kappa B (NF-кB) P50, tumor necrosis factor-α (TNF-α) and Bcl-xL mRNA in rats brain after cerebral ischemia-reperfusion. Methods Sprague-Dawley rats were randomly divided into normal control group (NC group), cerebral ischemia-reperfusion group (I/R group), fastigial nucleus stimulation (FNS) group, and fastigial nucleus lesion (FNL) group. A focal cerebral ischemia-reperfusion model was established with middle cerebral artery occlusion (MCAO). 7 and 14 days after operation, the infarct volume was measured, and the protein of NF-кB P50 in rats brain was detected with Western blotting; the expression of TNF-α and Bcl-xL mRNA was detected with RT-PCR. Results Compared with I/R group, the expression of NF-кB P50 protein increased in FNS group (P<0.05), with the decrease of expression of TNF-α mRNA (P<0.01) and increase of Bcl-xL mRNA (P<0.05), while the infarct size decreased (P<0.01). There was no significant difference between FNL group and I/R group for all the measurements (P>0.05). Conclusion FNS could induce the expression of P50 protein and Bcl-xL mRNA, and inhibit the expression of TNF-α mRNA, and reduce infarct size, which may associated with the neuroprotection of central nervous system from injury.

Objective To investigate the effect of pioglitazone (PIO) on the expression of peroxisome proliferators-activated receptor γ (PPARγ),nuclear factor-κB (NF-κB) c-Rel and anti-apoptosis factor Bcl-xL in cultured Wistar rat cortical neurons after oxygen-glucose deprivation/reoxygenation (OGD/R).Methods The rat cerebral cortical neurons were primarily cultured in vitro and a model of OGD/R was induced.The rats were divided into 7 groups:normal,OGD 4 h/R 6 h,OGD 4 h/R 12 h,OGD 4 h/R 6 h + PIO,OGD 4 h/R 6 h + PPARγ inhibitor T0070907 (TIO),OGD 4 h/R 12 h + PIO,and OGD 4 h/R 12 h + TIO groups.Western blot was used to detect the expression of PPARγ and NF-κB c-Rel protein in neurons.Reverse transcriptionpolymerase chain reaction assay was used to detect the expression of Bcl-xL mRNA in neurons.Results Western blot analysis showed that the expression levels of PPARγ and NF-κB c-Rel proteins after OGD/R were increased significantly compared to those of the normal group (P ＜0.01).After giving PIO,the expression levels of PPARγ and NF-κB c-Rel proteins were further increased,and they were significantly higher than those in the OGD 4 h/R 6 h and OGD 4 h/R 12 h groups (P ＜0.01),and after giving TIO,the expression levels of PPARγ and NF-κB c-Rel proteins were decreased,and they were significantly lower than those in the OGD/R group (P ＜0.05) and the corresponding PIO group (P ＜0.01).Reverse transcription-polymerase chain reaction analysis showed that the expression level of Bcl-xL mRNA in the OGD 4 h/R 6 h group was significantly higher than that in the normal group (P ＜0.01).The expression level of Bcl-xL mRNA in the PIO group was significantly higher than that in the OGD 4 h/R 6 h and OGD 4 h/R 12 h groups (P ＜0.01).After giving TIO,the expression of Bcl-xL mRNA was decreased.It was significantly lower than that in the OGD/R and corresponding PIO groups (P ＜ 0.05 and P ＜ 0.01).Conclusions PIO can upregulate the expression of PPARγ protein in cultured cortical neurons after OGD/R,and then increase the expression of anti-apoptotic factor Bcl-xL mRNA of NF-κB c-Rel regulation.This may be the part mechanism of PPARγ neuroprotective effect.

Objective To investigate neuroprotective mechanisms of vinpocetine by observing the effects of vinpocetine injection on the expressions of peroxisome proliferators-activated receptor γ(PPARγ),nuclear factor (NF)-κB p65,cyclooxygenase-2 (COX-2) in the ischemic cortex,and infarct volume after focal cerebral ischemia-reperfusion in rats.Methods A focal cerebral ischemia-reperfusion injury model was induced by suture method.The rats were randomly divided into a normal control,a cerebral ischemiareperfusion and a vinpocetine groups.They were also divided into either a day 7 subgroup or a day 14 subgroup (n =6 in each subgroup) according to the reperfusion time.Western blot was used to detect the expression levels of PPARγand NF-κB P65 in the ischemic cortex.Triphenyl tetrazolium staining was used to detect the volume of cerebral infarction.Results Western blot showed that at day 7 and 14 after cerebral ischemia-reperfusion,expression levels of PPARκ (all P＜0.001) and NF-κB p65 (all P＜0.001) in the cerebral ischemia-reperfusion group were significantly higher than those in the sham operation group,the expression levels of PPARκ (all P ＜0.05) in the vinpocetine group were significantly higher than those in the cerebral ischemia-reperfusion group,but the expression levels of NF-κB p65 (all P ＜0.05) were significantly lower than those in the cerebral ischemia-reperfusion group.Reverse transcription polymerase chain reaction showed that COX-2 mRNA expression levels were upregulated significantly at day 7 and 14 after cerebral ischemia-reperfusion compared with the sham operation group (all P ＜ 0.001),the expression levels of COX-2 mRNA in the vinpocetine group were significantly downregulated compared with the cerebral ischemia-reperfusion group (all P＜ 0.05).The infarct volumes at day 7 (134.308± 9.954 mm3vs.185.543 ± 9.100 mm3;q=10.659,P＜0.001) and at day 14 (137.865 ± 9.094 mm3vs.183.210±4.368 mm3;q=11.166,P＜0.001) in the vinpocetine group were significantly less than those in the cerebral ischemia-reperfusion group.Conclusions Vimpocetine significantly reduces infarct vohme after focal cerebral ischemia-reperfusion,its mechanism may be associated with upreguhtion of PPARγexpression and downreguhtion of the expressions of NF-κB p65 and COX-2.

The prevalence of various types of mental illness has reached 17.5％, and the current treatment of mental illness generally includes western medicine, psychotherapy and physical therapy. Due to the high disability rate, low cure rate and easy recurrence, mental illness has become a major public health problem that seriously affects human health and social stability. And it has attracted the attention of the government and society. At present, the typical western medicine for treating mental illness has serious side effects, while new types of medicine for treating mental illness has a slow efficacy. Physical therapy has an unstable effect, and the side effects of drugs for treating mental illness lack effective method. These problems are expected to be successfully solved through traditional Chinese medicine, acupuncture and acupoint stimulation. This paper puts forward the integrated traditional Chinese and western medicine for the treatment of mental illness, and strives to build a technical system for the treatment of mental illness with integrated Chinese and Western medicine through the organic combination of multidisciplinary and multi-technology.Meanwhile, it lists some classic cases of treatment in order to provide reference for those who are keen on the integrated Chinese and western medicine in the treatment of mental disease.

Objective:To learn about the status of iodine deficiency disorders in children and pregnant women in coastal areas of Guangxi Zhuang Autonomous Region (Guangxi for short).Methods:From January 2017 to December 2020, 12 counties (cities, districts) in Beihai City, Qinzhou City and Fangchenggang City in coastal areas of Guangxi were selected as the survey sites to carry out iodine deficiency disorders monitoring. Each county (city, district) was divided into five areas according to administrative regions: East, West, South, North and Middle. One township (town) was selected from each area, and 40 non-boarding children aged 8 to 10 (age balanced, half male and half female) and 20 pregnant women were selected from each township (town) as the survey subjects. Edible salt samples and urine samples were collected from children and pregnant women to detect salt iodine and urinary iodine levels; thyroid volume of children was determined and the rate of goiter was calculated.Results:From 2017 to 2020, a total of 8 905 children were monitored, and the median salt iodine of children was 23.4 mg/kg, and the medians salt iodine in each year were 23.7, 22.8, 23.5, 23.6 mg/kg, respectively; the median urinary iodine of children was 164.7 μg/L, and the medians urinary iodine in each year were 161.2, 169.7, 156.0, 171.1 μg/L, respectively; 30 of them had goiter, the rate of goiter of children was 0.34% (30/8 905). A total of 6 626 pregnant women were monitored, and the median salt iodine of pregnant women was 23.5 mg/kg, and the medians salt iodine in each year were 23.7, 22.5, 24.3, 23.8 mg/kg, respectively; the median urinary iodine of pregnant women was 139.6 μg/L, and the medians urinary iodine in each year were 129.6, 131.6, 134.4, 175.0 μg/L, respectively.Conclusions:The iodine nutrition of children in coastal areas of Guangxi is at an appropriate level (100 - 199 μg/L), and the rate of goiter has reached the national iodine deficiency disorders elimination standard (< 5%). But pregnant women are at risk of iodine deficiency (urinary iodine < 150 μg/L).

【Objective】 To explore the application value of different language assessment tools in the assessment of language development of 12-month-old high-risk infants, and to screen out simple and valid language assessment tools. 【Methods】 A total of 217 11- to 13-month-old high-risk infants who were followed up at the outpatient service for high-risk infants at the child health clinic of Guiyang Maternal and Child Health Hospital from March 2022 to May 2023 were selected as the study subjects. Their language was evaluated by Early Language Milestone Scale (ELMS), Putonghua Communicative Development Inventory (PCDI) and Ages and Stages Questionnaire-Third Edition (ASQ-3). With Gesell as the gold standard for the assessment of language, the area under receiver operating characteristic curve (AUC), sensitivity, specificity, accuracy, positive predictive value, negative predictive value, Youden index and Kappa value of the three tools were calculated. Spearman correlation analysis was used to analyze the correlation between the different language assessment scales. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was used to evaluate the three tools. 【Results】 1)Among 217 high-risk infants, 78 preterm infants was the most (35.94%). The rate of delayed language development detected by Gesell, ELMS, PCDI-comprehension, PCDI-expression, ASQ-3 were 5.5%, 7.8%, 36.4%, 30.0% and 11.5%, respectively. 2)ASQ-3 had the strongest correlation with Gesell language region (rs=0.607, P<0.01) and it had the most AUC (AUC=0.812, P<0.05). The consistency between ASQ-3 and Gesell was moderate (Kappa=0.56, P<0.01). ASQ-3 had the highest sensitivity(91.7%), accuracy(93.1%), negative predictive value(99.5%) and Youden index(0.85), and ELMS had the highest specificity(94.6%). 3) Comprehensive evaluation of three tools by the TOPSIS indicated that ASQ-3 was the best, followed by ELMS and PCDI-comprehension was the worse. 【Conclusion】 Among the three assessment tools, ASQ-3 has the highest value in assessing the language development of 11- to 13-month-old high risk infants, and it may be necessary to expand the age range and establish a national norm of ELMS and PCDI in the future.
