Objective To assess the change of plasma adrenomedullin(ADM)and endothelin(ET)in patients with essential hypertensin. Methods Concentrations of plasma ADM and ET were measured in 18 healthy control subjects and 52 patients with essential hypertension, 36 patients of which had no target organ damage, while 16 patients of which were complicated with renal impair. Results The concentrations of ADM and ET were significantly higher in patients with renal impair than in patients without organ damage. Plasma concentrations of ADM and ET were strongly positively correlated with blood urea nitrogen levels and serum creatinine levels. A strong inverse correlation between GFR and plasma concentrations of ADM and ET was found. Conclusion The increase of plasma ET and ADM may have an intimate relation to the renal function. ADM and ET may play some important role in the pathophysiologic makeup of hypertension and hypertension with renal dysfunction. ADM may act against excessive vasoconstrictor ET increased in essential hypertension and may be part of a compensatory mechanism to offset further development of renal impair.

Objective To investigate the effect of vitamin D on pulmonary function in patients with chronic obstructive pulmona-ry disease,and to explore its possible mechanism.Methods Patients with chronic obstructive pulmonary disease admitted in the hospital were randomly divided into 2 groups,one group of patients were given regular COPD treatment (control group,30 cases), the other group of patients were given vitamin D on the basis of conventional therapy(experimental group,30 cases).Pulmonary function test and C reaction protein (CRP)determination in the 2 groups were performed,the contents of PaO2 ,PaCO2 were also determined.Results Compared with the control group,lung function improvement in experimental group were more obvious,and the the number of acute attack significantly reduced(P <0.05).The concentration of CRP in experimental group was significantly lower after treatment than before treatment(P <0.05),while the concentration of CRP in control group didn′t change significantly (P >0.05).Conclusion Vitamin D contributes to the improvement of pulmonary function in patients with COPD,and its mecha-nism might relate to the reduction of inflammatory reaction.

Laryngeal interarytenoid neurilemmomas (LIN) is a benign encapsulated tumor originating from the schwann cells lining nerve fibers. Even though LINs are extremely rare in incidence, they could present with potential threat to the airway and thus requiring prompt diagnosis and treatment. Here, we report two cases of LINs. Both patients underwent excision of the tumor via microlaryngeal endoscopic procedures and recovered well postoperatively without complications. No recurrence was observed postoperatively on routine follow-up after 14 months.

Objective To investigate the expression of adiponectin Mrna in adipose tissues of spontaneously hypertensive rats (SHR) and the effects of Fosinopril (Fos) and osartan (Los) on adiponectin Mrna.Methods Twenty 22 - week old male SHR rats were randomly divided into four groups:SHR group,Fos group,and Fus + Los group.Five 22 - week old male WKY rats were used as control.The body weigh,cuff-tail blood pressure,urinary microprotein and urinary N-acetyl-β-D-glucesaminidase were determined.RT-PCR were applied to determine the expression of adiponectin Mrna in adipose tissues.Results At the eighth week,systolic blood pressure of rats in SHR group was significantly higher than those in the other four groups (P＜0.05).The levels of urinary microprotein,urinary NAGase in the WKY group,Fos group,Los group and Fos + Los group were significantly lower than those in SHR group(P＜0.05).RT-PCR analysis revealed that the expression of adiponectin Mrna in SHR group was obviously decreased,compared with WKY goup.Adiponectin Mrna expression in Los group,Fos group and Fos + Los group were increased compared with SHR group(P＜0.05).Conclusions The expression of adiponeetin Mrna is down-regulated in adipose tissues of SHR.After intervention with Fusinopril and Losartan,the adiponectin Mrna expression was up-regulated in adipose tissues of SHR,the levels of urinary microprotein and urinary NAGase were obviously increased in SHR and the levels of urinary microprotein and urinary NAGase were obviously decreased.

OBJECTIVE To analyze the significance of serum infectious markers in different sources and investigate the prevetion strategy of nosocomial infection in clinical laboratory. METHODS The serum infectious markers(HBsAg,anti-HCV,anti-HIV and syphilis antibody) were detected in outpatient,inpatient and physical check-up people from Jun 2007 to Jun 2008. RESULTS The total percentage of HBsAg,anti-HCV,anti-HIV or syphilis antibody positive in outpatient,inpatient and physical check-up people was 43.30%,13.56% and 7.26%,respectively.The positive rate of HBeAg in outpatient,inpatient and physical check-up people was 12.29%,1.78% and 0.71%,respectively.The average infection rate of syphilis was 1.75% in inpatients,but in inpatients above 60 years old it could be 3.75%.Twenty-one cases were reconfirmed of HIV positive by the reconfirmation laboratory of CDC in Human Province. CONCLUSIONS The positive rates of four serum infectious markers in outpatient or inpatient are markedly higher than that in physical check-up people(? 2=10 117.6,P

OBJECTIVETo compare the clinical efficacy differences between acupuncture combined with moxi-bustion plaster and electroacupuncture (EA) for nerve-root type cervical spondylosis.

METHODSA total of 60 casesof nerve-root type cervical spondylosis were randomly divided into a plaster group and an EA group, 30 cases ineach one. Patients in the plaster group were treated with regular acupuncture at Jiaji(EX-B 2) points and ashipoints, combined with moxibustion plaster at Gaohuang (BL 43); patients in the EA group were treated with EAat identical acupoints as plaster group. The treatment was given once a day, and 5 days were taken as one course;there was an interval of 2 days between courses and totally 2 courses were performed. The pain questionnaires andquantitative score of signs and symptoms were observed before and after treatment in the two groups. The clinicalefficacy of the two groups was compared.

Objective To analyze blood-CSF barrier and cerebrospinal intrathecal IgG synthesis in patients of multiple sclerosis, and explore the Protis software, IgG index and IgG synthesis rate in the and evaluation for cerebrospinal intrathecal IgG synthesis and blood-CSF barrier dysfunction. Methods 134 patients with neurological diseases were divided into threes groups, including multiple sclerosis group (34 cases), disease control group(80 cases) and control group(20 cases). IgG and ALB concentration of CSF and blood was detected by BN-Ⅱ. The oligoclonal IgG was detected by immunofixation electrophoresis. The relationship between Protis software results and IgG index or IgG synthesis rate was calculated and analyzed. Results The function of blood-brain barrier was almost normal in multiple sclerosis group,QALB was 4.5×10-3[(3.1-7.6)×10-3], there was no significance compared with control group (D=5.25, P>0.05). there were 31 patients with oligaclonal bands in cerebrospinal fluids in multiple sclerosis group (34 patients) with the positive rate of 91.2%. In multiple sclerosis group the intrethecal IgGIF, IgG index and IgG synthesis rate of 24 hours were 31.25% (11.65%-71.45 %), 0.93% (0.80%-1.04%), 24.25 mg/24 h(15.25-46.15 mg/24 h) ,the results were all higher than that in control group (D=175.5, 112.5,103.4,P<0.05). And in multiple sclerosis group there was no significant difference among the intrethecal IgGIF, IgG index and IgG synthesis rate of 24 hours, the positive rate of oligaclonal bands (P>0.05). In disease control group(80 patients) QALB Was 35.2×10-3[(18.5-55.5)×10-3] ,the result was significantly higher than control group (D=102.7, P<0.05), the oligaclonal bands were all negative, IgG index and IgG synthesis rate of 24 hours were 0.75(0.69-0.82) ,44.29 mg/24 h(20.35-65.98 mg/24 h) were both higher than control group(D=85.6,98.5,P<0.05). In disease control group the positive rate of intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours were 0 (0/80), 40.0% (32/80), 72.5% (58/80) respectively, IgG index and its positive rate both increased alone with the lesion degree of blood-brain barrier increasing (P<0.05). And there was similar trend in the IgG synthesis rate of 24 hours. There were significant correlations among intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours in multiple sclerosis group (r=0.788, 0.695 ,P<0.05). However there was no correlation among intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours in disease control group (r=0.000,P>0.05). Conclusions The Protis software can be used to analyze the intrathecal IgGIF and reflect the actual status of intrathecal IgG synthesis more accurately. Protis software has great application value for clinical diagnosis for nervous system disease.
