Objective To explore the clinical manifestations, electroencephalographic characteristics and therapeutic effect of drugs in children with Jeavons syndrome. Methods The clinical and electroencephalographic characteristics and thera-peutic effect of drugs were analyzed in 4 children with Jeavons syndrome. Results Among the four children there were 3 female and 1 male. The age at the onset of the disease was from 1 to 6 years. The typical clinical manifestations of this disease were brief, fast and repeated eyelid myoclonia (EM) with or without absence seizure. The typical electroencephalography (EEG) in two patients showed 3-6 Hz generalized spike and waves and polyspikes burst, and the eye closure and intermittent photic stimu-lation helped to induce discharges and clinical events. The typictal EEG in the other two patients showed 3.0-3.5 Hz generalizedδslow wave rhythm burst. The drugs of choice for treatment was sodium valproate monotherapy in two cases, levetiracetam in one case, sodium valproate combined with levetiracetam in one case. During the follow-up, seizures were controlled in one case, decreased in frequency in two cases and were still frequent in one case. Conclusions Jeavons syndrome is one of the idiopathic and generalized epileptic syndromes and characterized by EM with or without absence seizure. Video EEG monitoring plays an important role in the diagnosis of this disease. Sodium valproate and levetiracetam were effective for this disease.

ObjectiveTo analyze the technique and clinical effect of percutaneous nephrolithotomy combined with endoscopic balloon dilation in the treatment of upper ureterostenosis with recurrent renal calculi. MethodsFrom June 2008 to June 2011,18 ureteral stenosis patients with the history of ureteral open surgery,postoperative residual or recurrent kidney stones were treated.There were 8 males and 10 females with the age of 27 -48 years.Fourteen cases were with hydronephrosis of 2 -4 cm,3 cases were with hydronephrosis of 5 -6 cm and 1 case was with hydronephrosis ＞6 cm.Subsequent stone size ＜ 1 cm was found in 15 cases,1 -3 cm in 3 cases,＞3 cm in 1 case.All patients were treated with percutaneous nephrolithotomy ultrasonic lithotripsy combined with balloon dilatation.The stone clearance rate,hydronephrosis changes,complications and IVP situation before and after surgery were analyzed.ResultsAll the 18 cases were completed surgery successfully.There was 1 (6％) case with renal hemorrhage 3 days after the surgery and controlled with DSA hemostasis.There was 1 case accepted adjusting double-J tube by ureteroscopy.Sixteen (89％) patient's stones were completed removed.One case with residual calyceal stones size ＜5 mm was not further treated.There was 1 case treated with nephrectomy because of renal stone with infection.The patients were followed up for 6 to 36 months.Fourteen cases with hydmnephrosis improved significantly; 3 cases with no significant changes but improved following balloon dilation.All patients achieved significant improvement in imaging study comparing of preoperative and postoperative data.ConclusionThe use of percutaneous nephrolithotomy combined with endoscopic balloon dilation is a safe and efffective treatment option in the treatment of kidney stones with ureteral stenosis.

Objective To investigate the feasibility of urethral reconstruction with colonic mucosa graft in the treatment of complex long urethral stricture.Methods The clinical data of three cases with complex long urethral stricture were reported and analyzed.Patient ages were 71,64 and 48 yrs and the course of disease was three months,six months and six yrs,respectively.The length of urethral stricture was 13,18 and 12 cm.Removing the narrow urethral segment and intercepting the length from 12 to 18 cm sigmoid colon and stripping colonic mucosa were performed.Urethral reconstruction was done with a free graft of colonic mucosa.Follow-up included urethrography,uroflowmetry,and urethroscopy.Results The urethral reconstructions were completed successfully.The urinary peak flows of the patients were 16.7 ml/s,19.6 ml/s and 26.4 ml/s at six weeks post operation.Urethrography revealed the graft urethral lumens were bulky three months after the operation.In urethroscopy,the colonic mucosa was found to be of good color and the anastomotic site healed well.Patients were followed-up 28,16,and three months,respectively,and were all voiding well.Conclusions Colonic mucosa graft urethroplasty is a feasible procedure for the treatment of complex long urethral stricture.

Objective To construct the recombinant plasmid containing human filaggrin gene,purify and identify the immunoreactivity of the recombinant protein,and establish the indirect ELISA to detect AFA for diagnosis of RA.Methods The constructed plasmids were transformed into E. Coli Rosettagami(DE3).This fusion protein was purified by NAT chromatography.ELISA coated with the fusion protein Was established to detect the AFA in serum of patients,which included 114 cases of RA,56 cases of SLE,32 cases of OA and 40 cases of normal controls. The correlation between the results of AFA and anti-CCP in RA group were compared. Results 321 bp fragment of filaggrin gene was amplified and the recombinant expression vector pET-28a( + )-filaggrin was constructed. The sequence of filaggrin gene was the same as the sequence reported in the literatures. The Rosetta-gami (DE3) strains of E. Coli with recombinant vector showed high level of filaggrin protein after induction. The SDS-PAGE showed that the plasmid expressed the filaggrin fusion protein with molecule weight of 14 000 Da. The expression protein could be purified by Ni-NAT with activity. The absorbance value of AFA in RA group was 0.473 ±0. 248 while they were 0. 160 0. 088, 0. 121±0. 070, 0.050 0. ±018 in SLE, OA and normal groups respectively. There were significant differences of absorbance values of AFA between RA and SLE, OA, control group (t = 12.004, 14. 464, 18.078, P<0. 01, respectively). The positivities of anti-filaggrin in RA, SLE and OA were 48.2%, 5.4% and 3. 1% respectively. The positivities of AFA were significantly different between RA, OA and normal control groups (x~2 = 67. 088, P < 0. 01). There was positive correlation of results between AFA and anti-CCP antibody (r = 0.42, P < 0. 05 ) . The consistency rate of results between AFA and anti-CCP was 70. 1%. Anti-CCP was negative in 10 out of 114 patients with AFA positive. AFA can be used to diagnose RA with sensitivity of 48. 2% , specificity of 96.9% , positive predictive value of 93. 2% and negative predictive values of 67. 9% . Conclusions The purified human filaggrin fusion protein is successfully purified. The indirect ELISA method based on the recombinant protein shows good sensitivity and specificity. Joint detection with AFA and anti-CCP can improve the positive rate of detection.

s were 0.573±0.016, 0.707±0.008 and 0.711±0.013). Conclusions CXCL10 can express stablely in MCF-7 cell lines, which resulted in down-regulation of expression of VEGF and STAT3 gene. CXCL10 played an important role in anti-tumor effect.

AIM: To evaluate the implication of CXCL10-loop3-EGF fusion protein for the activities of targeting tumor and anti-angiopoiesis. METHODS: RT-PCR was preformed to amplify CXCL10 coding sequence from PBMC activated by IFN-γ. CXCL10-loop3-EGF fusion gene, which was conducted by Over-Lap Extention PCR, was hinged up with plasmid pTG19-T, transfected to E. coli DH5α and processed positive colony selection. After ligated with plasmid pET32a(+), recombinant CXCL10-loop3-EGF fusion gene was then transfected to E. coli Origami B (DE3) and induced to express its coding fusion protein his-CXCL10-loop3-EGF. The recombinant fusion protein CXCL10-loop3 -EGF was purified by His-bind affinity chromatograph, enterokinase cleavage, ultrafiltration and dislysis. The transwell chemotatic test and HUVEC angiopoiesis inhibition test were performed to determine the anti-tumor responses and anti-angiopoiesis activity of CXCL10-loop3-EGF fusion protein. RESULTS: CXCL10-loop3-EGF fusion protein was successfully constructed and confirmed by SDS-PAGE analysis and Western blotting. Significant PBMC chematatic activity and HUVEC anti-angiopoiesis activity were observed. CONCLUSION: CXCL10-loop3-EGF fusion protein, which has perfect anti-tumor activity, is successfully constructed.

AIM: To investigate the immunologic mechanism of CXC chemokine ligand 10(CXCL10) and its receptor CXC chemokine receptor 3 (CXCR3 ) involved in the process of endometriosis (EM). METHODS: Serum samples were collected from 3 groups; EM patients without operation (n = 76) , EM patients with operation (n = 10) and the normal control persons (n =76). CXCL10 and CA12S concentrations were detected by means of ELISA and chemilumino-metry. Cell surface antigens on the activated PBMC - CD3 and CXCR3, as well as CXCR3 subgene - CXCR3A and CX-CR3B were tested by flow cytometry (FC) and RT - PCR when PBMC was separated from women with EM ( n = 10) and without EM (n = 10), and then activated. RESULTS: Serum CXCL10 concentrations between three groups were signifi-canly different (P < 0.05). Compared to normal control group, although the supernatant CXCL10 concentration and CD3~+ /CXCR3~+ PBMC number in EM group has no significant difference (P >0.05) , highly expressed CXCR3B in EM group rather than CXCR3A was observed. CONCLUSION: CXCL10 in women with EM is low, indicating that it plays a vital role in the process of EM and immune system of the women with EM is defected and impaired. The immunoreactivity of PBMC from both EM patients and normal person is same to activated signal, but the productions are different: PBMC in EM group mainly express CXCR3B but PBMC in normal person mainly express CXCR3A after activation, which may be one of the immune mechanisms that EM escapes from immunological lethal effect of the infected host.

ObjectiveTo evaluate the efficacy,safety and clinical value of anterior urethral fusion to treat diphallia.MethodsA 17-year-old male patient with complete penile diphallia was treated in March 2011.The physical examination showed two completely separated mature penis; urethrography,and urethroscope showed the two urethras were completely separated and entered the bladder respectively.Two anterior urethras were incised respectively at ventral sides ( from the meatus to bulbar urethra) and then two incised anterior urethras were splintered by a continuous suture with 4-0 polyglactin sutures in side and side.Two penises were splintered into one.The nocturnal penile tumescence test and the penis vibration thresholds were assessed before,and after surgery..ResultsThe patient was followed up for 12 months.There was no hematoma,urinary fistula,urinary incontinence and other complications postoperatively.The penis was recovered with normal appearance; urination and morning erection of penile were normal.6 months after surgery,there was no significant difference in the nocturnal penile tumescence and penis vibration thresholds detection ( P ＞ 0.05).ConclusionThe operation of anterior urethral fusion is a safe and efficient surgical treatment to treat partial complete penile diphallia with less complication and no worse effect on urination and erection of penile.

OBJECTIVETo explore the clinical and gene mutation characteristics of children with peroneal myoatrophy FGD4 mutations.

METHODThe clinical data of a patient with peroneal myoatrophy with novel FGD4 gene mutations were collected, the related literature was searched from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, National Center for Biotechnology Information and PubMed (up to December 2014) by using search terms"muscular disorders, atrophic"peripheral nervous system diseases"genes". The clinical features and treatment of the patients with FGD4 gene mutations were studied.

RESULTThe patient was a 10-years-old boy, he was presented to our clinic due to lower extremity weakness for 3 years, worsening for one year with normal family history and birth history. When he was 6 years old, his feet turned inward as he walked, at 7 years of age, his toes pointed toward the ground, the heel could not touch the ground, the right foot was more serious. During the recent year his symptoms were worsened, manifested as clubfoot, foot drop, arched feet, crane legs, difficult in squatting, walking with swaying gait, easy to fall. He was brought to a number of domestic general hospitals' neurology clinic, he was clearly diagnosed as peroneal myoatrophy, but failed to make typing. Electromyography (EMG) showed neurogenic damage (peripheral neuropathy - motor and sensory fibers are involved). Target gene sequencing showed that the child had FGD4 genes compound heterozygous mutation: c. 338A> G and c. 1730G> A, where the former was inherited from his father, the latter inherited from his mother, it was a new mutation unreported previously. Literature search retrieved six reports (all in English literature) with FGD4 10 cases with mutations, which were expressed as peroneal myoatrophy, but were homozygous mutation.

CONCLUSIONThis study found the FGD4 4th and the 14th exons' c. 338A> G and c. 1730G> A heterozygous mutations, and this mutations may lead to peroneal myoatrophy.

The clinical data of a case with late-onset isolated sulfite oxidase deficiency(ISOD)admitted in the Department of Neurology, Children′s Hospital, Zhejiang University School of Medicine in July 2021 were retrospectively analyzed.Fifteen previously published cases of late-onset ISOD were also reviewed.The patient was a girl, who was hospitalized because of " motor regression with mental retardation for 5 days" at 1 year old.The manifestations of the patient were extrapyramidal symptoms, regression of motor development and seizures.The level of urinary sulfites in the patient was increased.Magnetic resonance imaging (MRI) features were bilateral pallidus and substantia nigra.Gene sequencing suggested a pure missense mutation of the sulfite oxidase( SUOX) gene c. 650(exon5)G>A(p.Arg217Gln). In 16 cases of late-onset ISOD, the median age at onset and diagnosis was 10.5 months and 34.0 months, respectively.The common clinical manifestations were hypotonia (13 cases), seizures (10 cases), movement disorders (9 cases), and ectopia lentis (6 cases). The most common brain MRI feature was pallidus changes (11 cases), followed by lesions of substantia nigra (5 cases), and cerebral atrophy (4 cases). Fourteen cases of late-onset ISOD showed a positive urinary sulfite test.The missense mutation of the SUOX gene was found in 9 cases.It suggested that brain MRI involvement of bilateral pallidus, high excretion of urine sulfites and the missense mutation of the SUOX gene were important diagnostic clues for late-onset ISOD.
