[ABSTRACT]AIM:Tostudytheeffectsofbaicalin(BC)onglialfibrillaryacidicprotein(GFAP)andnuclear factor-κB ( NF-κB) expression and neuronal apoptosis in juvenile rat hippocampus after status convulsion ( SC) .METH-ODS:One hundred and ninety five juvenile male Sprague-Dawley rats were randomly divided into 3 groups:normal saline pretreatment group (NS group), SC group and SC with BC pretreatment group (BC group).Each of these 3 groups would be subdivided into 5 subgroups sacrificed at 4 h, 12 h, 24 h, 48 h and 72 h after SC.The rat SC model was prepared by lithium-pilocarpine chemical method .The protein expression of GFAP and NF-κB was detected by the method of immuno-histochemistry .The mRNA expression of GFAP was detected by RT-PCR.The neuronal apoptosis was observed by TdT-mediated dUTP nick end labeling ( TUNEL ) .RESULTS: Compared with NS group , the GFAP positive cells was in-creased in SC group (P<0.05).Compared with SC group, the expression of GFAP was significantly reduced in BC group (P<0.05).Compared with NS group, the NF-κB positive cells was increased in SC group (P<0.05).Compared with SC group, the expression of NF-κB was significantly reduced in BC group .RT-PCR showed that the expression trend of GFAP mRNA was similar to that of the protein .Compared with NS group , the TUNEL positive cells in the hippocampus CA1 area in SC group increased significantly 12 h after SC (P<0.01), and reached a peak at 48 h.After the intervention with BC, the TUNEL positive cells decreased significantly between 12~48 h after SC (P<0.05 or P<0.01), but the number of TUNEL positive cells remained significantly greater than that in NS group (P<0.05).CONCLUSION: The expression of GFAP and NF-κB in the hippocampus increased after SC in rats .Baicalin decreases the expression of GFAP and NF-κB in hippocampus of rats with pilocarpine-induced seizures , and reduces the number of neuronal apoptosis , sug-gesting that baicalin may protect against the brain damage caused by status convulsion .

The association rules in data of traditional Chinese medicine prescriptions were analyzed using SQL Server 2008,which showed that 17 core compatible drug pairs were in line with the association rules.For example,platycodon grandiflorum combined with liquorice,known as Liquorice and Platycodon Decoction,can treat the principal and secondary aspects of a disease by ventilating the lungs and resolving the phlegm,removing the toxic substances and relieving the sore throat.Mining compatible drug pairs by analyzing their association rules can provide evidence for their clinical application.

Cartoons were used in teaching of medical decision-making analysis course to analyze and reveal the connotations in different decision-making models according the difficulties of students in understanding the teaching decision-making models.The cartoons could effectively improve the understanding of abstract analysis model and the meaning of teaching analysis model in students because they could directly show the iterative and optimizing computation process in decision-making analysis, thus laying a solid foundation for the accurate analysis and ra-tional explanation of the results.Teachers should make full use of the visual cognition potential of students, and fo-cus their attention on the knowledge transmission and information exchange between teachers and students when they design the cartoons in order to improve the classroom teaching effect of teaching decision-making model.

Objective:To study the changes and clinical significance of Th1/Th2 cytokines in peripheral blood of children with mycoplasma pneumoniae pneumonia(MPP).Methods:The clinical data of 60 MPP children who were treated in the hospital from January 2016 to February 2020 were retrospectively analyzed.According to disease progression, MPP children were divided into acute period group( n=29) and recovery period group( n=31). Another 50 healthy children who underwent physical examination in the hospital during the same period were enrolled as healthy control group.The levels of interleukin 4(IL-4) and γ-interferon(IFN-γ) were detected by double sandwich antibody ELISA. Results:The levels of IFN-γ and IL-4 in the acute period group[(1 235.24±254.64)ng/L, (781.13±113.09)ng/L] were significantly higher than those in the recovery period group[(545.38±58.57)ng/L, (331.27±64.18)ng/L]( t=14.683, 19.108, P<0.001, <0.001) and the control group[(477.96±46.61)ng/L, (241.86±39.07)ng/L]( t=20.534, 30.813, P<0.001, <0.001), while Th1/Th2 level(1.65±0.37) in the acute period group was significantly lower than that in the recovery period group(1.97±0.42)( t=3.123, P=0.003) and the control group(2.28±0.56)( t=5.405, P<0.001). The levels of IFN-γ and IL-4 in the recovery period group were higher than those in the control group( t=5.729, 7.805, P=0.003, <0.001), while Th1/Th2 level in the recovery period group was lower than that in the control group( t=2.652, P=0.010). Conclusion:There are immune disorders of Th2 advantages in MPP children.

Objective To explore the role of glucose-regulated protein 78 (GRP78),p38 mitogen-activated protein kinase(p38MAPK) signal pathway in seizure-reduced brain injures and the regulatory effect of Nimodipine on it.Methods Sprague-Dawley(SD) rats were randomly divided into status convulsion group (SC group),Nimodipine group(NM group),and a normal control group(NC group).The expressions of GRP78/Bip and p38MAPK mRNA and protein were detected by reverse transcription(RT)-PCR and immunohistochemistry.The expression of apoptosis cells was observed by TdT-mediated dUTP nick end labeling (TUNEL).Results (1) Immunohistochemistry:at 4 h after induction of status convulsion,the expression of GRP78 protein in the hippocampus CA1 domain began increasing slightly,and reached a maximum at 24 h,and then began decreasing slowly ; at 4 h after induction of status convulsion,the expression of p38MAPK protein in the hippocampus CA1 domain began increasing,and reached a maximum at 24 h,and decreased remarkably at 48 h.(2) RT-PCR:at 4 h after induction of status convulsion,the expression of GRP78 protein in the hippocampus CA1 domain began increasing slightly,and reached a maximum at 24 h,and then began decreasing slowly.The NM group was much higher than the SC group and the NC group(all P ＜ 0.05) ; at 4 h after induction of status convulsion,the expression of p38MAPK protein in the hippocampus CA1 domain began increasing,and reached a maximum at 24 h,and decreased remarkably at 48 h;the NM group was much lower than the SC group,and higher than the NC group (all P ＜ 0.05).(3) TUNEL:at 4 h after induction of status convulsion,the expression of the TUNEL positive cells in the hippocampus CA1 domain began increasing slightly,and reached a maximum at 48 h,and then began decreasing,and there was no difference between SC group and NC group;the NM group was much lower than the SC group(all P ＜ 0.05).Conclusions The correlation of the increased expression of p38MAPK and neuronal apoptosis indicates that GRP78 signal pathway may be mediated to cell apoptosis through p38MAPK.Nimodipine can affect the expression of GRP78/Bip and p38MAPK,and relieve endoplasmic reticulum stress,and lessen the pathologic damage to the hippocampus.

Shuangdan oral liquid (SDO) containing radix Salviae miltiorrhizae (Chinese name Danshen) and cortex moutan (Chinese name Mudanpi) is a traditional Chinese medicine using for treating vascular diseases. Danshensu (DSS) is a main effective monomer composition derived from radix Salviae miltiorrhizae and paeonol (Pae) from cortex moutan. Although the two herbs are widely used in traditional Chinese medicine, the pharmacological functions of their active compositions were not reported. Therefore, the research of DSS and Pae in mechanisms and pharmacodynamics interaction can provide scientific evidence to support clinical application. The diabetic nephropathy (DN) rats which were induced by streptozotocin (STZ) were treated with SDO, DSS, Pae, and DSS+Pae for eight weeks. The positive effects on DN animal models were investigated by detection of physiological and biochemical indexes and oxidative stress markers, within five treatments: SDO, DSS, Pae, DSS+Pae and insulin group. Compared with the model group, the DSS+Pae group improved the renal function, blood lipid metabolism and blood viscosity, increased the vitality of T-SOD or T-AOC and decreased the level of MDA or NO after the treatment. The study was successfully showed that the DSS+Pae group could delay the process of DN, especially in the renal injury part of histopathology changes. Our results suggest that the co-administration of DSS and Pae significantly may play a protective role in DN rats through decreasing the oxidative stress and improving the blood lipid metabolism mechanisms.

OBJECTIVE: To assess the value of copy number variation analysis based on next generation sequencing (CNV-seq) in prenatal diagnosis for women at advanced maternal age. METHODS: A prospective analysis was carried out for women who underwent amniocentesis at 18~36 weeks of gestation for fetal CNV-seq for advanced maternal age. RESULTS: For 1461 unrelated Chinese women with a singleton pregnancy, CNV-seq was performed for all samples successfully. The proportion of chromosomal abnormalities was 2.3% (34/1461), of which 44.12% were submicroscopic copy number variations (<5 Mb). CONCLUSION Pregnant women at an advanced maternal age should be informed for not only common trisomies but all pathogenic chromosomal aberrations. NGS was a sensitive and accurate approach for detecting CNVs.

Pediatric cough is a heterogeneous condition in terms of symptoms and the underlying disease mechanisms. Symptom phenotypes hold complicated interactions between each other to form an intricate network structure. This study aims to investigate whether the network structure of pediatric cough symptoms is associated with the prognosis and outcome of patients. A total of 384 cases were derived from the electronic medical records of a highly experienced traditional Chinese medicine (TCM) physician. The data were divided into two groups according to the therapeutic effect, namely, an invalid group (group A with 40 cases of poor efficacy) and a valid group (group B with 344 cases of good efficacy). Several well-established analysis methods, namely, statistical test, correlation analysis, and complex network analysis, were used to analyze the data. This study reports that symptom networks of patients with pediatric cough are related to the effectiveness of treatment: a dense network of symptoms is associated with great difficulty in treatment. Interventions with the most different symptoms in the symptom network may have improved therapeutic effects.
