Objective To analyze the diagnostic values of plasma albumin and total bilirubin, serum uric acid and inflammatory cytokines levels in patients with bipolar disorder.Methods A total of 48 cases of bipolar disorder patients were selected as research subjects ( study group) , and 45 cases of healthy people in the same period were chosen as control group.The plasma albumin, total bilirubin and serum IL-1β, IL-4, uric acid levels were compared and analyzed between two groups.Results The serum albumin, total bilirubin levels in study group were significantly lower than those in healthy control group, with significant difference (P<0.05).The serum IL-1β, IL-4 levels in study group were significantly higher than those in healthy control group, with a statistically significant difference (P<0.05).The serum uric acid levels in study group was significantly higher than that in healthy control group, with significant difference (P<0.05).Conclusion The serum albumin, total bilirubin and serum IL-1β, IL-4, uric acid levels can be used as a diagnostic reference index for bipolar disorder.

and adenovirns. The high rate of mixed viral infection brings clinical concern. ELISA combined with PCR improve the diagnostic sensitivity for norovirus, enteric adenovirns and astrovirus.

Objective To detect human metapneumovirus (hMPV)in respiratory intection rapidly and perform molecular analysis of hMPV.Methods Seven respiratory tract virus(11 subtypes)were assessed using multiplex PCR technology and flexible Multi-Analyte Profiling(suspension array).Human metapneumovirus was confirmed by using a real.Time reverse ranscriptase CR(RT-PCR)assay followed by sequencing.The cladogram analysis was performed further.Results The virus were detected in 40.2%(19/47)samples collected from clinicsl respiratory tract infections,including 8(42.1%)HRSV,7(36.8%)influenza virus,1(5.3%)parainfluenza virus,1(5.3%)rhinovirus,1(5.3%) coxsackievirus and 1(5.3%)human etapneumovirus infections.This is the first time that hMPV was deteced from clinical samples in Shenzhen.The sequencing of specific fragment of neucleoprotein of hMPV showed this hMPV shares over 98% homology with Beijing strain.Japan strain and Thailand strain.The cladogram analysis showed that they were in the same cluste.Conclusions Human etapneumovirus is a maior cause of children respiratory tract disease. Multiplex PCR technology and nexible Multi-Analyte Profiling were hish sensitive and high-throughput for detection of human metapneumovirus.They axe very robust and applicable in etiology analysis.

Objective To investigate the current status of coal-burning endemic fluorosis and the fluoride content in foods and drinking water in Hongya County,Sichuan Province.Methods Dental fluorosis and urinary fluoride were suveyed in children of 8～12 years old in two schools which repectively located in Gaomiao and Wawushan Town.The adults above 20 years old underwent clinical examination.At the same time,fifty adults above 20 years old in Garden Village were chosen to take forearm and calf X-ray films to find out the evidence of skeletal fluorosis.The content of fluoride in food such as bacon,corn,dry capsicum in Sanxing Village in Gaomiao Town and Futian Village in Wawushan Town as well as drinking water in five families in Sanxing Village were determined.Results The dental fluorosis rate of children was 40.76%(161/395),the dental fluorosis index was 0.86 in Gaomiao Town.The dental fluorosis rate of children was 14.36%(82/571),the dental fluorosis index was 0.31 in Wawushan Town.The medium value of the urine fluoride was 0.81 mg/L.ranged 0.16～3.89 mg/L.The positive rate oi the clinical examination of skeletal fluorosis was 5.27%(27/512),the X-rays detective rate was 4.00%(2/50).The medium value in bacon,corn,dry capsicum were 6.00,0.64,1.49 mg/kg.The averaged content of the fluoride in drinking water(0.14±0.06)mg/L of local household was within the eligible limitation.Conclusions It is currently a mild endemic disease in Hongya Country,its incidence is reduced apparently,pathogenetic environmental fluoride content is reduced.The main source of fluoride is from the preserved ham contaminated with fluoride,which is epidemiologically significant in endemic area of Hongya County.Defluoriding countermeasures should be taken in the endemic areas.

Objective To evaluate the influence of nuclear factor (NF)-κB activation in peripheral blood mononuclear cells (PBMCs) on vascular inflammation in elderly patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods The 40 elderly subjects (≥65years old) were classed into control, mild, moderate and severe groups (n = 10, respectively)according to polysomnography (PSG). After PSG, the samples of peripheral venous blood were collected, and PBMCs were isolated. Nuclear protein was extracted and NF-κB was measured by Western blotting. ELISA was applied to measure the levels of TNF-α and IL-6 in serum. Blood samples from 10 cases (moderate 5 and severe 5) were measured again after four weeks of continuous positive airway pressure (CPAP) treatment. Results The expression of NF-κB in PBMCs and the concentration of TNF-α in serum were significantly increased in severe and moderate OSAHS patients compared with controls (P＜0. 05). The NF-κB expression was positively correlated with AHI (r=0. 617, P＜ 0. 001) and TNF-α concentration (r = 0. 498, P＜ 0. 001 ), negatively correlated with LSaO2 (r= -0. 548, P＜0. 001), and not correlated with IL-6 concentration (r=0. 365, P=0. 201).The CPAP treatment could significantly inhibit NF-κB activation in PBMCs and reduce TNF-αexcretion (P＜0.05, respectively). Conclusions PBMCs may play an important role in vascular endothelial injury through NF-κB expression and TNF-α excretion in elderly OSAHS patients, which is closely associated with the severity of the syndrome and night hypoxemia. CPAP treatment can inhibit the pathophysiologic process effectively.

OBJECTIVE To study the isolation and resistance tendency of Acinetobacter calcoaceticus-baumannii to antimicrobial agents from 1998 to 2004 to provide valuable data for infection prevention and therapy. METHODS We reviewed the isolation rates,distribution in clinical specimens and wards,and the resistance rates of(A.calcoaceticus-baumannii)to 14 kinds of antimicrobial agents from 1998 to 2004. RESULTS There was an increasing tendency of isolation rates of A.calcoaceticus-baumannii every year,which was 0.18% in 1998 but 1.48% in 2004.In the seven years,there was the highest isolation rate of 70.58% in specimens from respiratory tract,the next was from the urine(9.42%),and blood(4.63%).Concerning the wards distribution,ICU had the highest rate of 47.28%.In 1998,A.calcoaceticus-baumannii had resistance rates more than 50% only to one kind of antimicrobial agents(aztreonam),but in 2004,it had increased to thirteen kinds(except cefoperazone/sulbactam).About the fourteen kinds of antimicrobial agents we inspected,that were increased in their resistance rate.The highest increasing of resistance rate was ceftazidime from 11.1% in 1998 to 88.9% in 2004,the imipenem was second for 0.0% to 64.8%,and the third was sulfamethoxazole/trimethoprim form 0.0% to 64.0%,while there still was an increasing resistance tendency to them. CONCLUSIONS The clinical isolation rate of A.calcoaceticus-baumannii is increasing,and it has higher resistance rates to many antimicrobial agents as well as an increasing resistance tendency to relatively susceptive antimicrobial agents every year.So physicians should prescribe on the basis of antimicrobial agents susceptibility tests in vitro.

AIMIn order to seek the marks of the genes, the relation between the influence of endurance training on aerobic ability and ACE Gene I/D Polymorphisms were studied.

METHODS102 army recruits of Han nationality from North China for an 18 week en durance training of 5000m distance. Their VO2(max), VT and the left ventricular structure and function were measured before and after the training. We also tested their ACE Gene I/D Polymorphisms with PCR-AFLP method.

RESULTSThe compliance of VO2(max), VT and left ventricular structure and function had improved after the training; the deltaVO2(max) of ID and II type was obviously higher than that of DD type (P < 0.05); there was obviously diference of deltaVO2(VT) in different ACE genotype (P < 0.05), the deltaVO2(VT) of type II was obviously higher than that of DD type (P < 0.05).

CONCLUSIONI allele has obviously hereditary advantage on the sensitivity to aerobic training in VO2(max) and VT, and type II has relation on the sensitivity to aerobic training in VT; there is no relation between I/D polymorphism and the sensitivity to aerobic training on the structure and function of left ventricle.
