Objective To observe the therapeutic efficacy of low-frequency electrical stimulation (LFES) plus acupuncture in treating deglutition disorders after cerebral stroke. Method Seventy-six patients were randomized into two groups. The treatment group (38 cases) was intervened by LFES plus acupuncture;the control group (38 cases) was by LFES. Result The water drinking test scores were significantly changed after the treatment in both groups (P<0.05); after the intervention, there were significant differences in comparing the water drinking test score, improvement score, and therapeutic efficacy grading between the two groups (P<0.05). Conclusion LFES and acupuncture are both effective in treating deglutition disorders after cerebral stroke, and the combination of the two methods can enhance the clinical efficacy.

Objective To investigate the association between HLA-DRB1 alleles and pemphigus vulgaris (PV) in a Han population in Sichuan.Methods Polymerase chain reaction with sequencespecific primer (PCR-SSP) method was used for low-resolution and high-resolution typing of HLA-DRB1 alleles in 19 patients of Han nationality with PV and 25 healthy controls in Sichuan.Allele frequencies were calculated,and differences in the allele frequency between the above two groups were compared by using chisquare test.Results Totally,9 kinds of DRB 1 low-resolution alleles and 19 kinds of DRB 1 high-resolution alleles were identified in the PV patients and healthy controls.Frequencies of the DRB1* 14 allele (39.47％[15/38] vs.8.00％[4/50],x2 =17.43,P ＜ 0.05) and DRB1*1405 allele (15.79％[6/38] vs.2.00％[1/50],x2 =4.25,P ＜ 0.05) were significantly higher in the PV patients than in the healthy controls.Conclusion The HLA-DRB1*14 allele may be a common susceptibility gene for PV in the Han population in Sichuan,and the HLA-DRB1* 1405 allele may be most closely associated with PV.

Objective:To observe the clinical effect of mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus for deglutition disorder of stroke patients in convalescence stage.Methods:A total of 136 patients conforming to the inclusion criteria were randomized into three groups by the random number table,including group A of 46 cases,group B of 44 cases and group C of 46 cases.Patients in group A received swallowing disorder therapeutic apparatus treatment,patients in group B received mind-refreshing and orifice-opening needling method treatment,and patients in group C received mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus treatment.The treatment was given once a day for 10 d as a course,the whole treatment lasted for 4 courses.Therapeutic evaluation items including water-swallowing test (WST),standardized swallowing assessment (SSA) and modified Barthel index (MBI) were measured before treatment,after treatment and at follow-up visit (2 months after treatment).Results:After treatment,scores of WST and MBI in all three groups increased significantly (all P＜0.05),while the SSA score dropped significantly (all P＜0.05).After treatment and during follow-up visit period,score of WST in group C was significantly higher than that in group A and group B (both P＜0.05),while the difference between group A and group B showed no statistical significance (P＞0.05);the SSA score in group C was substantially lower than that in group A and group B (all P＜0.05),the difference between group A and group B showed no statistical significance (P＞0.05);the MBI scores in group B and group C were substantially higher than that in group A (all P＜0.05),the difference between group B and group C showed no statistical significance (P＞0.05).After treatment and during follow-up visit period,the differences in overall therapeutic effect between group A and group B showed no statistical significance (P＞0.05),while the overall therapeutic effect in group C was substantially better than that in group A and group B (all P＜0.05).Conclusion:Both mind-refreshing and orifice-opening needling method and swallowing disorder therapeutic apparatus can alleviate symptoms of deglutition disorder of stroke patients respectively,and the combination of two methods can improve the therapeutic effect.

Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

Objective To investigate the potential clinical factors associated with the prognosis and relapse of adult onset Still's disease(AOSD).Methods The factors possibly influencing the prognosis and relapse of AOSD were analyzed by logistic regression and COX regression in the cohort study.Ninety-six con- secutive inpatients of AOSD diagnosed based on Yamaguchi criteria in the hospital from March 1996 to September 2004 were included in the study.Results Nine cases(9.4%)were lost during the follow-up. Eleven patients(12.6%)were diagnosed as other diseases(5 with other rheumatic diseases,4 with tumor and 2 with infections)in the 87 follow-up cases.In 76 cases,3 patients(3.9%)died and 33 patients(43.4%) got remission over one year after treatment.Splenomegaly(OR=3.14,95%CI=1.01～9.74)and treated with methotrexate(OR=0.22,95%CI=0.07～0.67)were associated with the prognosis from the logistic regression analysis of the 76 cases.The serum ferritin(RR=I.05,95%CI=1.01～1.08)and treated with methotrexate (RR=0.13,95%CI=0.02～0.76)were associated with relapse from the COX regression analysis of the 61 remis- sion cases.Conclusion We need to be very cautious in the follow-up of AOSD patients because some of them may change to other diseases.Methotrexate may be an importent therapy of AOSD not only in improve- ment the prognosis but also in reduction of relapse.

OBJECTIVETo study the effect of omega-3 polyunsaturated fatty acids (omega-3 PUFA) on inflammation in lung tissue of rats with severe scald and its mechanism.

METHODSSeventy-two adult SD rats were divided into sham scald group (SS, n = 8), treatment group 1 (T1, n = 32), treatment group 2 (T2, n = 32) according to the random number table. Rats in T1 group and T2 group were inflicted with 30% TBSA full-thickness scald, and then they were respectively injected with 100 g/L omega-3 PUFA (1 mL/kg) and 200 g/L long-chain fatty acid (2 mL/kg) via tail vein within 5 minutes after burn. The above two fatty acids with equivalent calories were continuously injected for 10 days (once a day). On post burn day (PBD) 1, 4, 7, and 10, serum level of TNF-alpha and level of macrophage inflammatory protein 1alpha (MIP-lalpha) in lung homogenate of T1 and T2 groups were detected, the levels of NF-kappaBp65 and macrophage migration inhibitory factor (MIF) in lung tissue of T1 and T2 groups were observed with immunohistochemical staining (recorded as score). Above-mentioned parameters were also determined in SS group. Data were processed with t test.

RESULTSThe levels of 4 parameters in T1 and T2 groups on PBD 1, 4, 7, 10 were higher than those in SS group (with t values from 3.411 to 8.782, P values all below 0.01), and those in T1 group on PBD 4, 7, 10 were lower than those in T2 group (with t values from 2. 321 to 2.785, P values all below 0.05). The serum level of TNF-alpha and levels of MIP-1alpha, NF-kappaBp65, and MIF in lung tissue in SS group was respectively (0.96 +/- 0.32) ng/mL, (76 +/- 16) pg/mL, 0.24 +/- 0.03, 1.31 +/- 0.03, and those in T1 and T2 groups all peaked on PBD 7 [(2.43 +/- 0.32) ng/mL, (210 +/- 56) pg/mL, 4.23 +/- 2.15, 4.69 +/- 1.83; (3.15 +/- 0.54) ng/mL, (274 +/- 64) pg/mL, 5.15 +/- 2.31, 5.37 +/- 2.16].

CONCLUSIONSOmega-3 PUFA can effectively reduce serum level of TNF-alpha and levels of MIP-1alpha, NF-kappaBp65, and MIF in lung tissue of rats with severe scald, showing that it has a protective effect against injury of lung tissue.
