BACKGROUND: Apolipoprotein(a) [Apo(a)] plays some role in promoting the formation of atherosclerotic plaque, and contains pentanucleotide repeats(PNR), which has a key value in genic research and in forecast on the increased risk of early atherosclerosis cerebral infarction (ACI). But the relationship between ACI and Apo(a) PNR in different races needs to be further investigated.OBJECTIVE: To investigate the relationship between the Apo(a) PNR polymorphism and ACI.DESIGN: A case-control study based on the ACI patients and normal people of Han nationality in Hubei.SETTING: Department of Laboratory in a hospital of a university.PARTICIPANTS: From February 1998 to March 1999, 82 ACI patients (ACI group) and 153 healthy controls(control group) were selected from the Department of Neurology, Central South Hospital and Yatai Hospital of Wuhan University. All patients were Han nationality in Hubei without any relatives.METHODS: Serum lipoprotein(a) [Lp(a) ], total cholesterol(TC), high density lipoprotein cholesterol(HDL-c), low density lipoprotein cholesterol (LDL-c), triglyceride (TG), apolipoprotein A Ⅰ (ApoA Ⅰ) and apolipoprotein B (Apo B) were tested respectively. Meanwhile, the PNR in the 5' control region of the Apo(a) was detected with polymerase chain reaction(PCR) and high voltage polyacrylamide gels electrophoresis. The results were analyzed with controlled analysis.RESULTS: The levels of serum Lp(a) [ (239.9 ±225.4) mg/L], TC [(4.76±0.74) nmol/L], TG[(1.74±0.60) mmol/L] and LDL-C [ (2.84 ± 0. 63) mmol/L] were remarkably higher in ACI group than those in control group, which were(133.5 ±97.7) mg/L in serum Lp(a), (4. 29±0.72) mmol/L in TC, (1.05±0.52) mmol/L in TG and(2.84±0.63) mmol/L in LDL-C, however, the level of HDL-C[ (0.88± 0.17) mmol/L] was remarkably lower in ACI group than that in control group [ ( 1.03 ± 0. 35 ) mmol/L], the differences were all significant( t = 3.65to9.18, P < 0.01) . The levels of ApoA Ⅰ [(1.13±0.15) mmol/L,(1.25±0.19) mmol/L] and ApoB[(0.93±0.12) mmol/L, (0.89± 0. 15 ) mmol/L] were no significant difference compared with those in control group. The duplicated frequency of the allele(TTTTA) 5(0. 098) in the ACI was remarkably higher than that in control(0. 026) (x2 = 5.62, P< 0. 05), The frequency of the allele(TTTTA) 9 in the ACI(0. 073) was remarkably lower than that in control (0. 213 ) (x2 = 7.83, P < 0.01 ), The frequency of the allele(TTTTA) 5 was also associated with low TC and high Lp(a) levels.CONCLUSION: It is suggested that the Apo(a) PNR polymorphism are associated with the susceptibility to ACI, and involved in the development of ACI.

OBJECTIVE:
Analyze the ABR testing results of local infants who failed the hearing screening and summarize its characteristics.
METHOD:
Carry on the first ABR test to 140 infants who failed the newborns' hearing screening when they are about 3-month age, the unusualities carry on the second ABR test at about 6-month age, and carry on the statistical analysis.
RESULT:
One hundred and forty infants with the first ABR diagnosis, 65 infants are normal, accounting for 46.43%; 75 infants have single or binaural ear hearing disorder, accounting for 53.57%, single ear 17.14%, binaural ear 36.43%, of which mild hearing disorder takes most, accounting for 27.14%, the profound hearing loss is also not extremely rare, accounting for 14.29%. Between male and female hearing disorder disease incidence rate difference is not remarkable statistics significance (P > 0.05). Between the number of high-risk in the hearing injury and non-high-risk after the comparison difference is not remarkable statistical significance (P > 0.05). With the population of above severe loss in hearing high-risk has the remarkable statistical significance with the non-high-risk comparison difference (P < 0.05). The second ABR subsequently visit 38 infants, 8 infants normal, total normal rate 52.14% (73/140), 16 infants mild hearing disorder 10 infants transfer normal either the change for the better, 6 infants do not have the change or the aggravation, 3 infants moderate hearing disorder 1 infant changes for the better, 2 infants do not have the change, 9 infants severe hearing disorder 3 infants have the change for the better, 3 infants do not have the change, 3 infants aggravate, 10 infants profound hearing disorder 9 infants do not have the change or the aggravation extremely, 1 example brain paralysis profound hearing disorder extension converges normally extremely. The non-high-risk whose hearing changes for the better is obviously higher than high-risk (P < 0.05).
CONCLUSION
Should develop newborns' hearing screening comprehensively with key attention to high-risk loss of hearing. The severe hearing disorder has the variability, and so on exceptional child hearing situation appraisal should be prudent to the brain paralysis; should establish perfect tracing, revisiting and managing system as soon as possible.

There is are large number of patients with chronic hepatitis B virus (HBV) infection. HBV not only damages the liver, but also involves the kidney. Hepatitis B virus-associated glomerulonephritis (HBV-GN) is secondary glomerulonephritis caused by HBV infection, and it is one of the most common extrahepatic complications of HBV infection. HBV-GN is mainly observed in children and young and middle-aged adults, with varying degrees of proteinuria as the main clinical manifestation, and it may be accompanied by hematuria and hypertension. Membranous nephropathy is the most common pathological type, followed by membrano-proliferative glomerulonephritis and IgA nephropathy. HBV-GN has an insidious onset and lacks characteristic symptoms and pathological manifestations, and thus it may be easily confused with various types of glomerulonephritis, which may lead to missed diagnosis and misdiagnosis. HBV-GN has a complex pathogenesis involving various links such as immune disorders, direct viral damage, and genetics, among which the theory of immune complex deposition has been widely recognized. In recent years, some important advances have been made in the research on the pathogenesis, diagnosis, and treatment of HBV-GN. This article summarizes the above issues, so as to provide a reference for clinical diagnosis and treatment.
