Chinese Journal of Clinical Infectious Diseases 2014;7(3):271-276
Hepatitis C virus (HCV)-related thyroid dysfunction is a common complication in patients with chronic hepatitis C,including Graves' disease,Hashimoto thyroiditis,destructive subacute thyroiditis,hyperparathyroidism or hypothyroidism,with or without abnormal autoantibodies or thyroidrelated antibodies.The possible pathogenesis of HCV-related thyroid dysfunction includes bystander activation,molecular mimicry,effects of interferon and susceptibility associated with genetic polymorphism on particular locus.By now,there is still no criteria for diagnosis and treatment of HCV-related thyroid dysfunction.For patients with mild HCV-related thyroid dysfunction,observation may be appropriate; and for those with serious symptoms,anti-thyroid drug,levothyrocine,surgery or symptomatic treatment may be applied according to clinical symptoms.This paper gives an overview of the prevalence,clinical characteristics and possible pathogenesis of HCV-related thyroid dysfunction.

Objective:To study the promotion effect of recombinant human acidic fibroblast growth factor ( rh-aFGF) on wound healing in children with surgery or accident injury. Methods: Totally 206 cases of injured children were randomly divided into two groups, the treatment group was given rh-aFGF, and the control group was treated with basic fibroblast growth factor (bFGF). The ob-servation of wound healing, infection and fat liquefaction in the children was recorded in 7 days,and the modification of scar, pigmenta-tion and adverse reactions were observed in 6 months after the treatment. Results:After the 7-day treatment by rh-aFGF and bFGF, the healing rate respectively was 88. 4% and 74. 2%, and the residual wound area was (2. 2 ± 1. 1) cm2 and (3. 9 ± 2. 4) cm2,respec-tively. Six months after the treatment, the scar incidence rate of the treatment group and the control group was 27. 2% and 67. 5%, and the incidence of pigmentation was 30. 1% and 69. 9%, respectively. Conclusion:Rh-aFGF is more effective than bFGF in pro-moting wound healing in children with surgery or accident injury. It can effectively promote wound healing, shorten the healing time, and diminish the area of scar and pigmentation.

OBJECTIVE:To clarify the bio-transformation form of apigenin in rats,and to speculate its possible metabolic path-way. METHODS:Rats were divided into blank group and medication group(apigenin 200 mg/kg,i.g.)with 6 rats in each group. Urine and feces samples were collected from 2 groups within 24 h after medication. After corresponding treatment,urine and feces samples were analyzed and detected by HPLC-IT-TOF-MSn under cation mode and anion mode. RESULTS:9 metabolites were iden-tified in urine sample of rats from medication group,i.e. 2,3-double bond reduction of apigenin (U1,U7,U8,U9),bonded to glucuronic acid(U2,U3,U4),bonded to sulphate(U5,U6,U7,U8,U9)and bonded to glucose(U2). 4 metabolites were iden-tified in feces sample of rats from medication group,i.e. 2,3-double bond reduction of apigenin(F3),bonded to glucuronic acid (F2)and bonded to glucose(F1). CONCLUSIONS:Apigenin mainly exists in form of prototype drug in rats. The reduction hap-pens on 2,3-double bond by the intestinal bacteria,and the product of apigenin boned to glucuronic acid or glucose can be formed when excreting in intestinal tract and rats in vivo,while the product of apigenin boned to sulphate can be formed only when excret-ing in rats in vivo.

Objective:To investigate the clinical and genetic mutation characteristics of a pedigree with familial exudative vitreoretinopathy (FEVR) associated with a LRP5 gene mutation. Methods:A pedigree investigation was performed in a two-generation Chinese Han family with FEVR, which was diagnosed in The First Affiliated Hospital of Xi'an Jiaotong University.Three family members, the proband and his parents, underwent ophthalmic examination, including visual acuity, intraocular pressure, slit-lamp microscopy, fundoscopy and wild-field fundus fluorescein angiography (FFA), to clinically characterize the FEVR phenotype.Peripheral blood of the families were collected for high-throughput sequencing and bioinformatics analysis to identify the pathogenic gene.Sanger sequencing verification was conducted for the detected mutation.The pathogenicity of identified mutations was analyzed according to the guidelines of the American Association of Medical Genetics (ACMG) with software such as Mutation Taster, Polyphen-2, PROVEN and REVEL.This study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of The First Affiliated Hospital of Xi'an Jiaotong University (No.2017-740). Written informed consent was obtained from each subject.Results:The proband was a 27-year-old male.Uncorrected visual acuity (UCVA) was 1.0 for his right eye and 1.2 for his left eye.Fundoscopy showed vascular tortuosity and vasodilation in the temporal peripheral retina of both eyes.FFA indicated that hairbrush-like vasculature and non-perfusion lesion in peripheral retina.The best-corrected visual acuity (BCVA) of the proband's mother, a 51-year old female, was 1.0 for the both eyes.Temporal retinal vascular tortuosity in her left eye was found with fluorescein leakage detected by FFA.The BCVA of the proband's father, a 56-year-old male, was 1.0 for both eyes.Leopard fundus and optic disc atrophy were visible.FFA result was normal.The result of genetic test showed that there were two novel gene mutations in the family with LRP5 gene c. 4110T>G(p.Cys1370Trp) and FSCN2 gene c. 1495G>A(p.Gly499Ser). According to guidelines of ACMG, LPR5 c. 4110T>G was a mutation with uncertain significance.Multiple software, such as MutationTaster, Polyphen-2, PROVEN and REVEL predicted that LRP5 c. 4110T>G mutation might cause detrimental effects on genes or gene products.REVEL scale was 0.93, which indicated that it might be a pathogenic variant. Conclusions:LRP5 gene c. 4110T>G(p.Cys1370Trp) may be a novel mutation for FEVR, which enriches the mutation spectrum of LRP5 gene.
