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 explore the relationship between the -344T/C polymorphism of aldosterone synthase (CYP11B2) gene and essential hypertension in Chinese Mongolian population.

METHODSBy cluster-sampling method, a total of 1575 Mongolian people in Tongliao city of Inner Mongolia were included in this study. And 417 subjects were normotension, 596 subjects were prehypertension and 562 subjects were essential hypertension. A survey was conducted to collect data by personal interview using a standard questionnaire, meanwhile fasting blood samples were drawn. Height, weight, waist circumference, blood pressure, blood-fat indexes and fasting plasma glucose were measured. The variant genotypes of CYP11B2 were identified by PCR assays. The relationship between the -344T/C polymorphism of CYP11B2 gene and essential hypertension were analyzed by multinomial logistic regression model.

RESULTSCrude prevalence of prehypertension among Mongolian people was 37.84% (596/1575) and hypertension was 35.68% (562/1575). The age-standardized prevalence of prehypertension was 38.57% and hypertension was 31.53%. The frequency of the T and C allele was 0.66 (481/728) and 0.34 (247/728) for normotension group, 0.69 (696/1042) and 0.33 (346/1042) for prehypertension group, 0.71 (706/998) and 0.29 (292/998) for hypertension group. The multiple logistic models showed CYP11B2 variant genotypes were associated with prehypertension (TT/CC, OR = 1.33, 95%CI: 0.87 - 2.01; TC/CC, OR = 1.74, 95%CI: 1.13 - 2.67; TC + TT/CC, OR = 1.49, 95%CI: 1.01 - 2.22); CYP11B2 variant genotypes were associated with hypertension (TT/CC, OR = 1.70, 95%CI: 1.07 - 2.70; TC/CC, OR = 1.59, 95%CI: 0.98 - 2.50; TC + TT/CC, OR = 1.66, 95%CI: 1.06 - 2.58).

CONCLUSIONCYP11B2 gene -344T/C polymorphism were associated with essential hypertension in Chinese Mongolian population.

OBJECTIVETo find out the dominant diseases in the clinic of modern acupuncture.

METHODSBy means of bibliometrics, clinical acupuncture study literatures from 1978 to 2004, searched from CBM database, were sorted and counted to show the different clinical utilizing quantities and developing trends of different disease groups in the acupuncture clinic.

RESULTSObviously dominant type: nervous system diseases; mature type: motor system diseases; developing type: 3 kind of diseases including psychosis; premature type: diseases related with surgery; steady type: 3 kind of diseases including digestive system diseases (diseases of liver and gallbladder are not included); pre-developing diseases: 5 kind of diseases including otorhinolaryngologic diseases.

CONCLUSIONAmong all these types, obvious advantage type and mature type are the most distinguishing. Developing type has the most significant ascending trend. Premature type has relatively strong developing potentiality.

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.
