Objective: To investigate the effective of Sanhua decotion(三化汤) on early brain water content,penetration of blood brain-barrier and the expression of aquaporin4(AQP4) in rats with acute cerebral ischemia/reperfusion(I/R).Methods: The string inserting method was employed to reproduce the rat model of focal cerebral I/R SD rats were randomly divided into sham operation group,model group and Sanhua decotion group.After I/R,each group was then divided into 6 hours,12 hours,24 hours,48 hours and 72 hours five subgroups.The brain water content was detected by the ratio of wet/dry weight to evaluate cerebral edema and the blood-brain barrier(BBB) damage was observed by Evan′s blue(EB) staining.The AQP4 mRNA and protein expressions were measured by reverse transcription-polymerase chain reaction(RTPCR) and immunohistochemistry respectively.Results: Compared with sham operation group,the brain water content,EB content,AQP4 protein and AQP4 mRNA expressions were increased at every time point after I/R in the model group(P

AIM: To investigate the mechanism of berberine’s inhibiting growth and metastasis of tumor by observing the effects of berberine on proliferation and apoptosis of human umbilical vein endothelial cells (HUVECs). METHODS: Cultured HUVECs were incubated with berberine. MTT assay and quantitative immunocytochemistry were used to detect cell proliferation and the expression of proliferation cell nuclear antigen (PCNA). Morphologic changes of apoptosis were observed by fluorescent staining, and Rhodamin123 was used to determinate mitochondrial membrane potential under the laser confocal microscopy. RESULTS: HUVEC proliferation was inhibited by co-incubating with berberine (20 mg/L) for 24 h and berberine (10 mg/L, 20 mg/L) for 48 h (P

This study performed phylogenic analysis on a dengue strain isolated from an outbreak of dengue fever in 2009 at Yiwu City of Zhejiang Province,China,and further to analyze the immunogenicity of E protein of this viral isolate.Firstly,the viral genome was amplified by RT-PCR and phylogenetic trees were constructed by MEGA 4 based on both nucleotide and amino acid sequences of E and NS1 proteins.The phylogenetic analysis showed that the similarity of Yiwu strain with the Guangzhou GZ1D3 strain and the India GWL-25 strain was over 99％.Secondly,the expression plasmid of E protein was constructed and transfected into 293T cells.The secreted E protein were then purified by sucrose density gradient centrifugation and used to inoculate BALB/c mice.The humoral immunity was evaluated by ELISA and neutralizing antibody analysis.Resuits showed that the E protein of Yiwu strain could induce dengue specific IgG antibodies and neutralizing antibodies.Therefore,the study found that the Yiwu strain was classified into the subtype Ⅲ of dengue virus type 3 (DENV-3),and the E protein of this strain had strong immunogenicity

Objective: To summarize the experience of endoscopic endonasal approach in the treatment of anterior skull base with intra-extracranial extension meningioma, and to analyze the perioperative quality of life of patients, and to discuss the safety and efficacy of the treatment. Methods: A total of 83 cases of anterior skull base with intra-extracranial extension meningioma admitted to Xuanwu Hospital, Capital Medical University from October 2007 to October 2019, who underwent endoscopic endonasal approach tumor resection, were retrospectively analyzed. The quality of life of the patients were evaluated by Anterior Skull Base Questionnaire (ASBQ) before and after surgery. The surgical techniques, extent of tumor resection, postoperative complications and the changes of patients' quality of life were summarized and analyzed. SPSS 23.0 software was used for statistical analysis. Results: A total of 57 anterior skull base with intra-extracranial extension meningioma patients were enrolled according to the inclusion and exclusion criteria, including 23 males and 34 females, aging (48.6±16.6) years. Fifty cases (87.7%) reached or exceeded Simpson gradeⅠ resection, and 7 cases underwent subtotal resection. Symptoms relief was as follows: headache relief in 45/50 (90%), vision improvement in 18/19 (94.7%), olfaction improvement in 6/45 (13.3%), mental symptoms improvement in 3/9 (33.3%), and seizure relief in 5/7 (71.4%). Postoperative complication included mental symptoms in 5 cases, cerebrospinal fluid leakage in 2 cases, epilepsy in 2 cases, frontal lobe hemorrhage in 1 case, and intracranial infection in 1 case. The follow-up period was 38 to 144 months. There were two cases recurring and no death. ASBQ assessment showed significant improvement in general condition, physical function, role function, mood disorder, pain, vision impairment, and sleep disturbance at 1 month postoperatively, with continued improvement thereafter, and reached stable at 6 months postoperatively. Conclusion: Endoscopic endonasal approach surgery is able to achieve safe and effective tumor resection for anterior skull base intra-extracranial extension meningioma, and the quality of life of patients can be improved steadily.
