AIM To explore the role of nitric oxide (NO) mediators in seizure behavior and the related expression of interlukin 6(IL 6). METHODS The IL 6 immunoreactivity (IL 6 ir) and behaviour were observed in kainic acid (KA) induced seizure following pretreatment with L nitroarginine( L NNA), a inhibitor of nitric oxide synthase(NOS), or the same number of moles of L arginine( L Arg). RESULTS The results showed that time dependent seizures were induced on animals after administration of KA (10 mg?kg -1 ), accompanied by the immediate enhancement of IL 6 ir in hippocampal structure, piriform area and cortex. The behaviors of rats were not markedly altered by chronic pretreatment with L NNA (50 mg?kg -1 ) or L Arg (40 mg?kg -1 ). However, after the administration of KA, the seizure behaviors were obviously different in the group of L NNA and L Arg respectively. Seizure was agrevated in the animals with L NNA pretreatment and many rats died at KA 3 hours, whereas seizure was alleviated after KA in the group of L Arg. IL 6 expression was apparently up regulated in some brain areas such as hippocampus in the group of KA pretreated with L NNA, but opposite effects appeared in the group pretreated with L Arg before KA injection. CONCLUSION These results indicate that endogenous NO mediators may alleviate the seizure behaviors and may down regulated the early expression of IL 6 in KA challenged seizure, but it the mechanism of the early expression of IL 6 with the homeostasis of endogenous NO mediator merits further study.nismoftheearlyexpressionofIL 6withthehome

AIM To observe the expression of inducible nitric ox ide synthase (iNOS) in the rats' hippocampus of kainic acid (KA) induced-seizur es and the effect of L-arginine(L-Arg) or L-nitroarginine(L- NNA) chronic intervention before KA. METHODS The expression of iN OS mRNA by RT-PCR and behaviour were observed after administration of convulsan t dose of KA (10 mg?kg -1 ) and pretreatment with NO predecessor (L-Ar g, 40 mg?kg -1 ) or a inhibitor of NOS(L-NNA, 50 mg?kg -1 ) befo re KA. RESULTS The time-dependent seizures were induced on rats after giving KA, and were improved and serious in the animals with L-NNA pr etreatment, but they were alleviated by L-Arg pretreatment before KA. Compa red with control, iNOS mRNA expression was feebly at KA 3 h, continuative improv ement accompanying KA time prolonged, and it was markedly enhanced at KA 24 h. I t couldn't be examined at KA 2 d or 3 d, and was obviously improved at KA 7 d a gain. iNOS mRNA appeared weak in the rats hippocampus with L-Arg pretreatme nt after KA 1 h, whereas it wasn't found in L-NNA pretreatment animals. CONCLUSION iNOS mRNA expression appeared in the hippocampus of seizu re rats at a few time after KA, and L-Arg chronic intervention before KA ha s a little effect on it.

Objective To investigate the effects of down-regulation of Beclin 1, which is an autophagy regulatory molecule, expression induced by RNA interference on the proliferation and apoptosis in skin fibroblasts of naked mole rat. Methods The expression levels of Beclin 1 were detected after starvation or H2 O2 treatment.The fibroblasts were transi-ently transfected with specific siRNA targeting Beclin 1 and then screened by real-time PCR and Western blot.Cell prolifer-ation and apoptosis were determined using CCK-8 detection kit and flow cytometry ( FCM ) .The expressions of related genes were detected by Western blot.Results The expression of Beclin 1 gene at mRNA and protein levels was signifi-cantly lower in fibroblasts of the naked mole rat.Starvation and H2 O2 treatment induced changes of the Beclin 1 expression. Inhibition of Beclin 1 gene expression can inhibit cell proliferation and induce early and late apoptosis.The protein levels of p53, BAX, Bcl2, LC3B, p-AKT and mTOR were reduced after transient transfection with Beclin 1-siRNA.Conclusions The expression of Beclin 1 in fibroblasts of naked mole rat are changed in response to starvation or H2 O2 stimulation.Inhi-bition of Beclin 1 gene expression can inhibit cell proliferation and induce apoptosis.Therefore, Beclin1 gene may play a regulatory role in autophagy, proliferation and apoptosis in the skin fibroblasts of naked mole rat.

OBJECTIVE: To investigate the clinical presentation, diagnosis and therapy of syphilis with sensorineural deafness. METHOD: Three patients of syphilis with sensorineural deafness were analyzed including the clinical manifestation, serum and therapy response. RESULT: Three patients of syphilis with sensorineural deafness: 2 cases with rapid plasma reagin (RPR) and treponema pallidum particle agglutination (TPPA) positive, 1 case with RPR negative and TPPA positive; 2 cases had been diagnosed with syphilis and treated once; 2 cases with sudden sensorineural deafness and tinnitus, 1 case with tinnitus and high-frequency hearing loss. All cases hadn't another identified cause of the hearing loss or tinnitus. Their hearing loss level weren't improved after therapy. CONCLUSION Sudden hearing loss or nervous tinnitus may be the clinical manifestations of syphilis with sensorineural deafness. It is easy to miss diagnosis in clinical work. Some lab examinations were necessary to diagnose the cases with the etiology unknown of hearing loss, tinnitus or nystagmic.

OBJECTIVE To study the extraction and enrichment technology of chrysosplenides A （CA） and I （CI） in Tibetan medicine Chrysosplenium axillare. METHODS HPLC method was used to determine the contents of CA and CI. The orthogonal experiment was used to optimize the extraction technology of CA and CI in C. axillare using total transfer rate of CA and CI as evaluation indexes， with volume fraction of ethanol， extraction temperature， extraction times and solid-liquid ratio as factors. The validation test was also performed. The enrichment technology of CA and CI in C. axillare was optimized using D101 macroporous adsorption resin as adsorbent， total contents of CA and CI as evaluation indexes， with the volume fraction and dosage of eluent for impurities and target components. The validation test was also performed. RESULTS The optimum extraction conditions of CA and CI from C. axillare were as follows： the medicinal powder of C. axillare was extracted by ultrasound at room temperature for 45 min at one time with 8 times of 50% ethanol. Results of validation tests showed that total transfer rate of CA and CI in C. axillare was 95.43% in average （RSD＝1.02%， n＝3）. The optimal enrichment technology was as follows： the sample solution was added into D101 macroporous adsorption resin column and stood for 1 hour； the impurities were eluted with 20% ethanol 4 BV （column volume）， and CA and CI were eluted with 50% ethanol 4 BV. The results of validation tests showed that total content of CA and CI was 322.7 mg/g in average （RSD＝1.05%， n＝3）， with average enrichment multiple of 11.61 times. CONCLUSIONS The study has successfully optimized the extraction and enrichment technology of CA and CI from C. axillare， and can provide reference for the development and utilization of CA and CI.

Objective: To examine the association of pre-pregnancy body mass and weight gain during pregnancy with macrosomia. Methods: From January 2015 to December 2015, a total of 20 477 pregnant women were recruited by probabilistic proportional scale sampling with simple randomization in Sichuan, Yunnan and Guizhou Provinces. Basic information of pregnant women, weight gain during pregnancy and weight of newborn were collected. A multiple logistic regression model was used to assess the association between the pre-pregnancy body mass and gestational weight gain indicators with macrosomia. Results: 20 321 mother-infant were included in the final analysis. 20 321 pregnant women were (30.09±4.10) years old and delivered at (39.20±1.29) weeks, among which 12 341 (60.73%) cases were cesarean delivery. The birth weight of 20 321 infants were (3 292.26±431.67) grams, and 970 (4.77%) were macrosomia. The multiple logistic regression model showed that after adjusting for the age of women, compared to the normal weight group in the pre-pregnancy, the overweight and obesity group elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.69−2.35) and 4.05 (95%CI: 3.05−5.39), respectively. After adjusting for the age, the pre-pregnancy BMI, delivery weeks, delivery mode and infant′s gender, compared to the weight-gain appropriate group, higher weight gain rate in the mid-pregnancy and excessive total gestational weight gain elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.66−2.39) and 1.80 (95%CI: 1.55−2.08), respectively. Conclusion The overweight before pregnancy, obesity before pregnancy, the rate of weight gain in the second trimester and the high total weight gain during pregnancy could increase the risk of macrosomia.
