Febrile seizure is one of the most common convulsive disease in childhood.Its pathogenesis is not yet clear.Sometimes the patients with febrile seizures may have fever after seizure and some epilepsy syndrome is characterized by febrile convulsions in the early stage, which makes the differential diagnosis particularly important.Studies have shown that cytokines and genes are involved in the pathogenesis of febrile convulsions.There are differences in the levels of interleukin-6 and interleukin-10 between febrile seizure and other diseases, and the underlying mechanism varies.This article discusses the research update on the expression of IL-6 and IL-10 in related fields from serum levels, cerebrospinal fluid levels, gene and therapeutic drug innovation, in order to provide ideas for clinical diagnosis, treatment and prevention.

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.

Objective To investigate and analyze the epidemiological characteristics of an epidemic situation of human brucellosis epidemic in Xinchang County Zhejiang Province,and provide experience for prevention and treatment of brucellosis.Methods Retrospective analysis was performed to collect the data of epidemic situation,field case investigation,serum test and hospital diagnosis and treatment,and the situation of epidemic situation in 2018 of Xinchang County and field investigation were summarized and analyzed.Results A total of 3 confirmed cases were reported in this outbreak,one of them was a laboratory diagnosed case of brucellosis,2 cases were closely contacted with sick animals,and those 2 cases were confirmed by serological tests (n =30).The source of infection was the purchase and slaughter of unquarantined goats.A total of 10 goats blood samples were collected in the inter-animal investigation,4 of them were positive.Conclusion Unprotected contact with infected goats is a major exposure factor,raising awareness and promoting publicity about the path of infection with brucellosis is the key to preventing brucellosis.

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.

Objective To evaluate the effect of weak laser on treating hypertension,hyperglycemia,and hyperlipidemia.Methods A questionnaire-based survey was carrried out nationwide among the users of wrist-band weak laser irradiation.Changes in blood pressure,blood lipids,and blood glucose were analyzed before and after treatment.The influencial factors of antihypertensive effect of weak laser irradiation were analyzed by univariate and multivariate linear regression method.Results Questionnaire forms were returned from 5801 users,among whom 1335 patients with hypertension,180 patients with hyperglycemia,and 129 patients with hyperlipidemia entered the final analysis.After treatment,systolic blood pressure (SBP) (t =53.16,P ＜0.001),diastolic blood pressure (DBP) (t =34.17,P ＜ 0.001),triglycerides (TG) (t =7.87,P ＜0.001),total cholesterol (TC) (t =8.78,P ＜ 0.001),and fasting blood glucose (FBG) (t =11.64,P ＜0.001) were significantly decreased (compared with pre-treatment levels).Compared with the baseline,SBP,DBP,TG,TC and FBG fell by 23.3 mmHg (14.50％) (1 mmHg =0.133 kPa),10.6 mmHg (11.40％),0.86mmol/L (28.70％),1.11 mmol/L (18.00％),and 3.64 mmol/L (34.40％).The decrease of DBP in patients without insomnia was significantly higher than that in insomnia patients (F =9.54,P =0.00),and the decrease of DBP in non-drinkers was significantly higher than that in drinkers (F =5.08,P =0.02).The decrease of TG was significantly higher in males than in females (Z =2.48,P =0.01),in patients with mental stress than in those without stress (Z =-2.16,P =0.03),and in smokers than non-smokers (Z =-2.17,P =0.03).The median irradation time was 616 d (1-5479d).According to the irradiation time,the patients were further divided into four group:＜ 272d,272-698d,699-1435d,and ＞ 1437d.The SBP declined by (-22.25±16.22),(-21.59±15.24),(-24.96±16.82),and (-24.66±15.88) mmHg,respectively,in these four groups (F =3.55,P =0.01).Multivariate linear regression analysis showed that the influencial factors of SBP variation included gender (β =-0.08,P =0.0178) and irradiation time (β =-0.09,P =0.0016).The factors influencing the change of DBP were gender (β =-0.10,P =0.0039),insomnia (β =0.09,P =0.0015),and alcohol consumption (β =0.10,P =0.0033).Conclusion Long-time weak laser external irradiation has certain effectiveness in treating hypertension,hyperglycemia,and hyperlipidemia.

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.

BACKGROUND:Previous studies have found that estrogen deficiency causes a reduction in the activity of bone marrow mesenchymal stem cel s (BMSCs). OBJECTIVE:To explore the effect of endothelial progenitor cel s (EPCs) on the BMSCs proliferation and apoptosis ability of osteoporosis rats. METHODS:Healthy female Sprague-Dawley rats, 6 weeks old, were enrol ed and subjected to bilateral ovariectomy to make osteoporosis models. BMSCs and EPCs were isolated using density gradient centrifugation combined with adhesion method, and identified with surface markers, cel proliferation and immunocytochemistry in vitro. We used Transwel inserts to establish EPCs and OVX-BMSCs indirect co-culture system. Control groups were OVX-BMSCs group and sham-BMSCs group in which rats were only subjected to remove the equal amount of fat tissues around the ovary. Flow cytometry was applied to detect BMSCs proliferation and apoptosis ability. RESULTS AND CONCLUSION:Compared with the control groups, the results of flow cytometry test showed that the proportion of OVX-BMSCs at S phase was significantly increased at 3 days of indirect co-culture with EPCs and the apoptosis rate was significanty reduced at 10 days of indirect co-culture with EPCs (both P<0.05). These results suggest that EPCs can promote the proliferation but inhibit the apoptosis of OVX-BMSCs.

[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 .
