ABSTRACT
OBJECTIVE Cognitive deficit is a com-mon comorbidity in temporal lobe epilepsy(TLE)and that is not well controlled by current therapeutics.Currently,how epileptic seizure affects cognitive performance remains largely unclear.The subiculum is the major out-put of the hippocampus,which projects to entorhinal cor-tex and other more distinct brain regions.Physiologically,the subiculum codes spatial working memory and naviga-tion information including place,speed,and trajectory.Importantly,prior studies have noted the importance of the subiculum in the beginning,spreading,and generaliz-ing process of hippocampal seizure.How seizure-activated neurons in subiculum participate in cognitive impairment remains largely elusive.METHODS In this study,we sought to label the subicular seizure-activated c-fos+ neu-rons with a special promoter with enhanced synaptic activity-responsive element E-SARE in the subiculum,combined with chemogenetics and designer receptors exclusively activated by designer drugs(DREADDs),Ca2+ fiber photometry approaches,and behavioral tasks,to reveal the role of these neurons in cognitive impairment in epilepsy.RESULTS We found that chemogenetic inhibi-tion of subicular seizure-tagged c-fos+ neurons(mainly CaMK Ⅱ α+ glutamatergic neurons)alleviates seizure generalization and improves cognitive performance in the hippocampal CA3 kindling TLE model.While inhibition of seizure-labeled c-fos+ GABAergic interneuron shows no effect on seizure and cognition.As a comparison,che-mogenetic inhibition of the whole subicular CaMK Ⅱ α+ neuron impairs cognitive function in na?ve mice in basal condition.Notably,inhibition of subicular seizure-tagged c-fos+ neurons enhances the recruitment of cognition-responsive c-fos+ neurons via increasing neural excitability during cognition tasks.CONCLUSION Our results dem-onstrate that subicular seizure-activated c-fos+ neurons contribute to cognitive impairment in TLE,suggesting sei-zure-tagged c-fos+ neurons as the potential therapeutic target to alleviate cognitive impairment in TLE.
ABSTRACT
Numerous studies have reported that the resistance of biofilm bacteria to antibiotics can be up to 10-1 000 fold higher than that of planktonic bacteria. Bacterial biofilms are reported to be responsible for more than 80% of human microbial infection, posing great challenges to the healthcare sector. Many studies have reported that plant extracts and their active ingredients can inhibit the formation and development of bacterial biofilms, including reducing biofilm biomass and the number of viable bacteria in biofilms, as well as eradicating mature biofilms. This review summarized the plant extracts and their active ingredients that are inhibitory to bacterial biofilms, and analyzed the underpinning mechanisms. This review may serve as a reference for the development of plant drugs to prevent and treat biofilm infections.

ABSTRACT
Objective To investigate the effect of dezocine on emergence agitation (EA) during recovery from sevoflurane-based anesthesia in children.Methods Ninety ASA Ⅰ or Ⅱ children,aged 3-6 yr,weighing 14-31 kg,were randomized into 3 groups (n =30 each):fentanyl group (group F),dezocine group (group D)and control group (group C).Anesthesia was induced with inhalation of 8 ％ sevoflurane and iv injection of atracurium 0.5 mg/kg and remifentanil 1 μg/kg and maintained with inhalation of 2％-3 ％ sevoflurane and infusion of remifentanil at 0.1-1.0 μg· kg-1 · min-1.In groups F,D and C,fentanyl 2 μg/kg,dezocine 0.05 mg/kg and the equal volume of normal saline were injected intravenously 10 min before the end of surgery,respectively,and inhalation of sevoflurane was stopped at the end of operation.The extubation time and length of stay in the postanesthesia care unit (PACU) were recorded.Agitation and the duration were recorded when the children were in PACU.The degree of EA was assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale.Pain was evaluated using the Children' s Hospital of Eastern Ontario Pain Scale (CHEOPS) and sedation was measured with Ramsay score.The complications such as respiratory depression,postoperative nausea and vomiting were recorded within 24 h after operation.Results Compared with group C,the incidence of EA and PAED scores were significantly decreased and the duration of EA was shortened in groups F and D,CHEOPS scores were decreased at each time point after operation and Ramsay scores were increased at T1 in group F,and CHEOPS scores were decreased and Ramsay scores were increased at each time point after operation in group D (P ＜ 0.05).Compared with group F,the incidence of EA and PAED scores were significantly decreased,CHEOPS scores were decreased at each time point after operation,and Ramsay scores were increased at T2 (P ＜ 0.05),and no significant change was found in the duration of EA in group D (P ＞ 0.05).There was no significant difference in the extubation time and length of stay in the PACU between the three groups (P ＞ 0.05).Conclusion Dezocine 0.05 mg/kg can safely and effectively prevent EA during recovery from sevoflurane-based anesthesia in children and produces better efficacy than fentanyl.
ABSTRACT
Objective To investigate the long-term programming effects on pubertal reproductive function by immunological challenge in early life. Methods Female Sprague-Dawley rats were administered by endotoxin (lipopolysaccharide, LPS) at a dosage of 50 μg/kg and saline intraperitoneally on postnatal day 3 and 5. Body weight was measured weekly. Puberty onset ( vaginal opening) and oestrous cyclicity were monitored from postnatal day 30. At the age of 6 weeks, bilateral ovariectomy was performed. The histological and morphological change of the ovaries (the thickness of the theca interna and the number of different kinds of follicles) were observed and the immunoreactivity of the ovarian sympathetic nerve markers (low affinity receptor of nerve growth factor, p75NGFR) was evaluated by immune staining. Results Immunological challenge (exposed to LPS) in early life delayed vaginal opening significantly [LPS-treated (40.6 ±0.7) days versus controls ( 38. 6 ± 0. 5 ) days, P ＜ 0. 05], decreased the percentage of normal oestrous cyclicity ( LPS-treated 26. 1% versus controls 66. 8% , P＜ 0. 05 ) , decreased the total number of different types of follicles (primordial follicles: LPS-treated 610 ±47 versus controls 1181 ±57, P ＜ 0. 05; primary follicles: LPS-treated 624 ±41 versus controls 960 ± 30, P ＜ 0. 05 ; preantral follicles: LPS-treated 183 ± 16 versus controls 260 ± 14, P ＜ 0. 05; antral follicles: LPS-treated 32 ± 4 versus controls 79 ± 7, P ＜ 0. 05) and increased the thickness of the theca interna [LPS-treated ( 15. 8 ±0. 4) μm versus controls (11.4 ±0. 3) μm, P ＜ 0. 05]. The immunostaining of p75NGFR was obviously enhanced in the LPS-treated ovaries when compared with that of controls ( P ＜ 0. 05 ) . Conclusions Immunological stress during early critical developmental windows could have long dysfunctional effects on the pubertal reproductive function. It delayed puberty onset, reduced the percentage of the normal oestrous cycles, decreased follicles reserve and increased the thickness of the theca interna which might involve the up-regulation of the local ovarian sympathetic nerve activity.
ABSTRACT
Objective To study the therapeutic effects of Bizhi pills in mycobacterium tuberculosis infection.Methods KunMing mice were infected by intratail-vein injection with mycobacterium tuberculosis H37Rv, then treated with saline(A)or Rifampin(B) or Bizhi pills(C).The lungs,hvers and spleens were taken to observe their pathological changes,weighted and performed mycobacterial culture after 4 months of treatment.Results After 4 months of treatment, indexes of the lung in group C were markedly lower than that in group A (P＜0.05),but higher than that in group B,although the differences were not significant.The lesion of lung in group C were similar as that in group B,and were lessen than that in group A.No obvious lesion of lung was observed in 8 mice of group B and C,but the differences were not significant.Swell of spleen was observed in 9 mice in group A,2 mice in group B and5 mice in group C,the differences were significant(P＜0.01).The numbers of bacteria in the lung and spleen of the female mice of C group were remarkably less than that in group A, and decreased 4 times and 10 times respectively compared with group A(P＜0.01),the numbers of bacteria in the lung and spleen of the male mice of C group were less than that in group A, and decreased 3 times and 2 times respectively.However,the numbers of bacteria in the lung and spleen of the male mice of B group was decreased 14 times and 7 times respectively(P＜0.01).Conclusions The therapeutic efficacy of Bizhi pills in mice with mycobacterium tuberculosis infection is significant, but it is not as good as Rifampin.The therapeutic efficacy of Bizhi pills in female mice of mycobacterium tuberculosis infection is better than that in male mice.
ABSTRACT
Objective: To investigate the expression of peroxisome proliferator actived receptor ? (PPAR ?)and the inducement of apoptosis by PPAR ? ligand in renal cell carcinoma(RCC) derived cell lines.Methods:RT-PCR and Western blot analysis were performed to determined the expression of PPAR ? mRNA and protein in two RCC derived cell lines(786 O and A498) and two normal kidney(NK) derived cell lines(HK 2 and HMCC). Two RCC cell lines were treated with 50 ?mol/L troglitazoned for and evaluated for the effects of antidiabetic thiazolidinediones (TZDs) on the cells apoptosis by fluorescence microscopy and DNA ladder assay.The mutative expressions of Bcl 2 and Bax before and after TZDs treatment were also performed by western blot analysis. Results: The expression of PPAR ? was observed to be stronger in 786 O and A498 cells than in HK 2 and HMCC cells by RT-PCR and Western blot analysis. Treated with 50 ?mol/L troglitazone (for 48 h) it induced typical apoatosis in 786 O and A498 cells. After treatment, a decrease in Bcl 2 expression in RCC cells was observed by Western blot analysis,and the expression of Bax,however,was up regulated.Conclusion: The results reveal that troglitazone has the tumor suppressive effect on RCC cells. High affinity PPAR ? ligands (TZDs) may be the candidates for a novel approach to the treatment of this refractory neoplasm.
ABSTRACT
Objective To set up a novel clinical method for storage of oocytes by slowly freezing and successful pregnancy by intracytoplasmic sperm injection (ICSI). Methods The frozen oocytes (n=33) in metaphase Ⅱ (28),which were normal in morphology,were denuded of their cumulus-corona complex.The protective freezing solution contained 1,2-propanediol (1.5 mol/L) and sucrose (0.35 mol/L) and the process was slow for freezing and rapid for thawing.The recipients of these oocytes received hormone replacement therapy (HRT). Results A high survival rate of oocytes (32/33) was obtained when the sucrose concentration was 0.35 mol/L.ICSI induced a higher fertility rate (23/28),a good embryo cleavage rate (21/23) and a satisfactory embryo morphology for thawed oocytes.Embryo transfers were performed in 6 cycles/6 cases. Four cases got clinical pregnancy by demonstration of four gestation sacs on B ultrasonic examination 7 weeks after ICSI,1 fetal was first trimester spontaneous abortion,another 3 survival fetal were ongoing pregnancy and the first case gestation week is 17 weeks. Conclusions This study is the first successful application of human oocyte cryopreservation in China and this method can increase the survival rate of freezing oocytes.It’s easy to carry out,low in cost and high in the recovery rate of oocytes after thawing.
