Infantile spasms is a type of refractory epilepsy syndrome.This epilepsy syndrome is characterized by special tonic spasms,a peculiar set of electroencephalographic findings termed hypsarrhythmia,and arrest of psychomotor development in most patients.The etiology is not clearly understood.Recently,mutations of the arista less related homeobox gene(ARX),cyclin-dependent kinase-like 5(CDKL5)/se-rine/threonine kinase 9 gene(STK9),membrane associated guanylate kinase 2 gene(MAGI2),et al,and abnormal chromosome had been found to be responsible for infantile spasms.In this review,progress of infantile spasms in molecular genetics are discussed.

Objective To investigate the effects of recombinant vaccine Bifidobacterium bifidum (Bb) pGEX-Sj14-3-3 on splenocyte apoptosis in BALB/c mice.Methods Ninety-six BALB/c mice were randomly divided into two groups according to their body mass:per os group (PO) and intranasal immunization group (IN),with 48 mice in each group.All mice were orally and intranasally immunized with recombinant vaccine Bb(pGEX-Sj14-3-3).Four mice in each group were sacrificed on weeks 0,2,4,6,8,10,12,14,16,18,20 and 22,respectively,after immunization,and splenocytes were separated and cultured with or without ConA stimulation.The apoptotic rates of splenocytes were detected by flow cytometry.Results It showed that apoptotic level of splenocytes in both groups remarkably increased after 2-4 weeks without ConA stimulation (PO:0.069 ± 0.005,0.076 ± 0.010; IN:0.037 ± 0.002,0.075 ± 0.002),and the value reached the peak on the 4th week,and the differences were statistically significant compared with that of week 0(all P ＜ 0.05).Apoptotic level of splenocytes in both groups with ConA stimulation increased after 2-6 weeks(PO:0.089± 0.006,0.098 ± 0.010,0.060±0.007; IN:0.054 ± 0.001,0.093 ± 0.003,0.058 ± 0.012),and the value also reached the peak after 4 week,respectively.The differences were statistically significant compared with that of week 0 (all P ＜ 0.05).Apoptotic level of splenocytes in each group with ConA stimulation was significantly higher than that without ConA stimulation.Conclusion It is suspected that the recombinant vaccine Bb(pGEX-Sj14-3-3) may inhibit apoptosis of splenocytes in mice immunized orally or intranasally.

ObjectiveTo study the dynamic changes of IgG,IgG subclasses,IgE and IgA in sera of BALB/c mice immunized with recombinant Bifidobacterium bifidum (Bb) pGEX-Sj14-3-3 vaccine of Schistosoma japonicum.MethodsNinty six BALB/c mice were randomly divided into two groups:oral immunization group and intranasal immunization group,48 mice in each group.Mice were orally and intranasally immunized with recombinant Bb(pGEX-Sj14-3-3) vaccine,respectively.Four mice from each group were sacrificed,respectively,on weeks 0,2,4,6,8,10,12,14,16,18,20 and 22 after immunization and their sera from the eyeballs were collected.The levels of IgG,IgG subclasses,IgE and IgA were assayed with routine Enzyme-linked immunosorbent assay(ELISA).ResultsThe titers of IgG,IgG1,IgG2a,IgG2b,IgG3,IgE and IgA in both groups increased during the 2 - 22th,2 - 14th,2 - 22th,2 - 22th,2 - 20th,2 - 22th,2 - 22th weeks,respectively.The values reached the highest level on weeks 8,6,6,4,8,10 and 6,respectively,in the oral group,and the values were (0.065 ±0.001,0.021 ± 0.002,0.011 ± 0.001,0.015 ± 0.003,0.014 ± 0.002,0.011 ± 0.001,0.013 ± 0.002),respectively,as compared with the values on week 0(0.032 ± 0.001,0.015 ± 0.002,0.005 ± 0.002,0.005 ± 0.001,0.006 ± 0.001,0.006 ± 0.001,0.005 ± 0.001 ),the differences were statistically significant(P ＜ 0.05 or ＜ 0.01 ) except that of IgG1 and IgG2b.In the intranasal group these values reached the highest levels on weeks 4,6,4,4,8,10 and 8,respectively,and the values were (0.064± 0.003,0.022 ± 0.002,0.012 ± 0.003,0.019 ± 0.001,0.013 ± 0.001,0.015 ± 0.001,0.014 ± 0.003),respectively,as compared with the value on week 0,the differences were statistically significant(P ＜ 0.05 or ＜ 0.01 ) except that of IgG1 and IgA.ConclusionsTypes Th1 and Th2 mixed type immune responses can be induced in mice by immunization with the recombinant Bb(pGEX-Sj14-3-3) vaccine by early period of immunization (2th - 10th week).

Objective To construct and identify recombinant vaccine Bifwlobacterium bifidum(Bb)pGEX-Sj14-3-3 of Schistosoma japonicum(Sj). Methods Total RNA was extracted from adult Sj, antigen encoding gene Sj14-3-3 was amplified by RT-PCR and cloned into Escherichia coli (E. coli)-Bb shuttle expression vector pGEX-1λT to construct recombinant plasmid pGEX-Sj14-3-3. The recombinant plasmid was transformed into E. coli BL21 (DE3).The plasmid was extracted and identified by using BamH I and EcoR I. Then pGEX-Sjl4-3-3 was electroporated into Bb to construct recombinant Bb (pGEX-Sj14-3-3) vaccine. The extracted plasmid of the recombinant Bb (pGEX-Sj14-3-3) vaccine was identified by PCR, and the size of the products was compared with Sj14-3-3 gene of adult worms.Results Sj14-3-3 of 399 bp in length was amplified by RT-PCR. The products were digested by BamH I and EcoR I , and the fragments length of plasmid pGEX-Sj14-3-3 vector was 4947 bp, and of Sj 14-3-3 gene was 399 bp.The product of 399 bp Sj14-3-3 gene was also amplified by PCR from template of the extracted plasmid of the recombinant Bb(pGEX-Sj14-3-3 ) vaccine. The size of the product obtained was just the same as expected.Conclusion The recombinant Bb(pGEX-Sj14-3-3) vaccine of Sj is successfully constructed.

Objective To study the interactive debridement methods in treatment and nursing of the wound in patients with abdominal surgical incision infection.Methods In May 2010 to December 2013 in West China hospital of Sichuan University,54 patients with postoperative incision infection accompanied with tissue necrosis after gastrointestinal surgery were divided into two groups,23 cases who accepted interactive debridement treatment were set as the observation group,31 cases with traditional dressing hypertonic saline gauze debridement were named as the control group.The wound debridement completion time,wound healing velocity,wound healing time,dressing change frequency and cost were compared between two groups of patients.Results Compared with those of the control group,in the observation group,the wound debridement completion time was shorter,wound healing velocity was faster,dressing change frequency was longer.Although single dressing change cost was higher in the observation group,but the total dressing change cost was lower compared with the control group.Conclusions The interactive debridement methods used in treatment and nursing of patients with abdominal surgical incision infection showed good effect and safety,which is worthy of wide clinical application.

Objective To assess the clinical efficiency and side effects of topical mometasone furoate aqueous nasal spray for patients with naphazoline-induced rebound rhinitis. Methods A prospective, non-randomized and self-controlled study was applied. A total of 22 patients with naphazoline-induced rhinitis received two spray-puffs of 50 μg mometason furoate twice daily to each nostril in the morning for one week, followed by two spray-puffs of 50 μg mometason furoate once daily to each nostril every morning for another three weeks after withdrawn of naphazoline therapy. Nasal congestion was evaluated by visual an-alogue scale (VAS) recorded before and after treatment. Side effects like nose bleeding and perforation of the nasal septum was detected with rhinoscope. Results The statistical difference of VAS before and after treatment was significant. No adverse reac-tions as nose bleeding and perforation of the nasal septum were observed by the end of treatment. Conclusion It is safe and effective to use mometasone furoate aqueous nasal spray for treating rebound rhinitis induced by misuse of naphazoline nasal drop.

Objective To evaluate the use of flexible cystoscope in the surgical management of complex renal calculi. Methods Flexible cystoscope and a set of stone baskets were used to help the surgical of complex renal calculi via the renal pelvis incision or the dilated ureter during operation.A pyelostomy with the use of a Foley's catheter was carried out if necessary and the residual stones could be removed via the pyelostomy tract later on. Results 31 cases of complex renal stones have been surgically treated.Flexible cystostomy was used intraoperatively in 11,postoperatively for the removal of residual stones in 16 and being used both intra and postoperatively in 4.A total of 106 stones have been removed.26 patients ( 83.9 %) have been free from any stone.2(6.4%) have undergone ESWL followed by flexible cystoscopy to remove the residual stones.3 patients (9.7%),however,still had residual stones in spite of the above procedure. Conclusions Flexible cystoscopy as an adjuvant procedure is an effective means in the surgical treatment of complex renal calculi especially for the removal of residual stones.The procedure is simple,safe and less expansive.
