OBJECTIVETo investigate the inhibitory effects of bcl-xl antisense oligodeoxynucleotides (ASODN) on growth and gene expression of human nasopharyngeal carcinoma (NPC) in nude mice.

METHODSCNE-2Z cell line was implanted subcutaneously into nude mice. Twenty four h after implantation, bcl-xl ASODN and mismatch control oligonucleotides (SCODN) were injected subcutaneously into nude mice, respectively. The tumor volume and weight were measured twice weekly. The histopathological changes of the tumors were observed by HE staining. RT-PCR and Western-blot were performed for bcl-xl gene expression.

RESULTSGrowth of NPC was significantly inhibited in the ASODN therapy group as compared with that in the control group (P < 0.01). The growth inhibitory rate was 41.7% in the ASODN group and 19.0% in the SCODN group. The expression level of bcl-xl mRNA and protein was decreased in the ASODN group, whereas in the SCODN group there was no significant difference in contrast with saline-treated control group.

CONCLUSIONOur findings suggest that bcl-xl antisense oligodeoxynucleotides results in marked inhibition of NPC growth in nude mice. It may be a novel treatment approach for human nasopharyngeal carcinoma.

Argininemia is a rare, autosomal recessive, metabolic disorder caused by an hereditary deficiency of hepatocytes arginase due to ARG1 gene defect. Arginase is the final enzyme in the urea cycle, catalyzing the hydrolysis of arginine to ornithine and urea. Research advances in the clinical manifestations, diagnosis, treatment, prenatal diagnosis and genetics of argininemia were reviewed in this paper. The clinical manifestations of patients with argininemia are complicated and nonspecific so that clinical diagnosis is usually difficult and delayed. Progressive spastic tetraplegia, seizures and cerebella atrophy are common clinical features of the disease. Blood amino acids analysis, arginase assay and ARG1 gene analysis are important to the diagnosis of argininemia. Early diagnosis and a protein-restricted diet with citrulline and benzoate supplements can contribute a lot to improve patient prognosis. With the application of liquid chromatography-tandem mass spectrometry in selective screening and newborn screening for inborn errors of metabolism, an ever-increasing number of patients with argininemia are detected at the asymptomatic or early stages.

OBJECTIVETo compare therapeutic effects of auricular point sticking combined with Tongshiji treatment and simple Tongshiji treatment on child ametropic amblyopia.

METHODSThree hundred children of ametropic amblyopia were classified as mild, moderate and severe groups, 100 cases in each group. The each group was again randomly divided into a simple Tongshiji treatment (control group) and a auricular point sticking combined with Tongshiji treatment group (observation group). Their therapeutic effects were compared.

RESULTSThe total effective rate in the observation group were 100.0%, 79.8% and 71.0%, and in the control group were 100.0%, 54.3% and 48.2% respectivety for mild, moderate and severe groups. For the mild amblyopia children, there was no significant difference between the two groups in the therapeutic effect; for the moderate and severe ametropic amblyopia children, the therapeutic effect in the observation group was better than that in the control group (P<0.05).

CONCLUSIONAuricular point sticking combined with Tongshiji treatment for child ametropic amblyopia is of characteristics of convenient manipulation, obvious and rapid therapeutic effect.

Construction of mutant strain is an essential method in pathogenesis researches. The conventional method for Brucella unmarked deletion mutant construction is based on suicide plasmid, but the efficiency is very low. In the present study, we first optimized the electroporation parameters, and then, the cloning plasmid pEX18Gm containing sacB was successfully used to construct unmarked deletion mutant of the type IV secretion system. This indicated that by using conventional cloning plasmid as suicide plasmid in Brucella, unmarked deletion mutants can be constructed with high efficiency.

Mitochondrial respiratory chain deficiency is a common cause of mitochondrial disease in children. This study aimed to review the clinical, enzymatic and genetic characteristics of a Chinese boy with progressive intrahepatic cholestasis due to mitochondrial respiratory chain complex I deficiency. The boy developed diarrhea from the age of 13 months, followed by progressive body weight loss, jaundice and weakness. His urine organic acids, blood amino acids and acylcarnitines profiles were normal. Mitochondrial respiratory chain complexes I to V activities in peripheral leukocytes were measured using spectrophotometric assay. Complex I activity was reduced. 5821G>A mutation was indentified by gene sequencing on tRNA-cys of mitochondrial gene in the patient and his mother. Vitamin supplements, liver protection, antibiotics and plasma infusion were not effective in the patient. Unfortunately, the boy died at the age of 17 months. Mitochondrial respiratory chain complex I deficiency is the most common mitochondrial respiratory chain disorder. This was the first case of intrahepatic cholestasis due to complex I deficiency confirmed by mitochondrial respiratory chain enzyme activity assay and gene analysis in China. It was concluded that mitochondrial hepatopathy is one of major causes of metabolic hepatopathy. Biochemical assay, mitochondrial respiratory chain complex activities assay and genetic analysis are crucial for the etiological diagnosis of metabolic hepatopathy.
