Objective:To observe vox acoustics features of patients of lung Qi deficiency,understand the influence of different extents of lung Qi deficiency on phonation,and expound the relationship between lung Qi state and phonation. Methods:Apply computer vox analysis system to test the vox sustainable vowel signal(i) of 65 cases of lung Qi deficiency and 20 cases of healthy persons respectively,observe and analyse their acoustics parameters(basic frequency,micro bother of frequency,slight bother of swing and standard yawp energy) of natural sound lowest bourdon and comfort sound and natural sound most alt. Results:For lung Qi deficiency patients,the basic frequency of 3 different phonations is lower than healthy persons,whose lowering trend increases with degrees of lung Qi deficiency,among which,under lowest bourdon of natural sound,there's marked difference of basic frequency between middle and severe lung Qi deficiency and healthy adults(P

Objective: To study the effects of TNF ? on wound healing. Methods: The skin lesion and incisions were made on mice and rh TNF ? was applied in both skin lesion and incision. Tissue strips were evaluated for tensiometry and histologic features after healing. Results: It was found that rh TNF ? markedly improved wound healing both in skin lesion and incision wound model, it also markedly enhanced the breaking strength of treated incision and increased wound cellularity in rh TNF ? treated groups. Conclusion: The results suggest that TNF ? play an important role in regulating inflammatory reactions of local injured tissues and it may improve the functions of fibroblasts, mononuclear phagocytes and endothelial cells. rh TNF ? of suitable doses can promote wound healing. This shows that TNF ?, as a wound healing promoter, has the potentials for clinical application.

Objective: To study the relationship between interleukin(IL) 6, IL 8, tumor necrosis factor alpha (TNF ?) and wound healing. Methods: In lower jaw gunshot wound, the expression of IL 6, IL 8, TNF ? in local soft tissues was assayed by using immunohistochemistry methods. The current levels of IL 6, IL 8, TNF ? in wound tissues was analysed by using image assay. Results: High expressions of these cytokines were observed in local soft tissues of wounds during the first 3 d after the gunshot. The cytokines expressions were different between the area near the bullet path and that far from the path. There was only one peak of the cytokines concentration in the area far from the bullet path, while there were 2 peaks of the cytokines concentration in the area near the bullet path.Conclusion: These results suggest that IL 6, IL 8, TNF ? play an important role in regulating inflammatory reactions of local injured tissues. They may improve the functions of fibroblasts, mononuclear phagocytes and endothelial cells and stimulate wound cells to produce and release other cytokines.

Objective To establish a method to simultaneously determine contents of alantolactone and isoalantolactone in Sanwei Ganlusan. Methods Contents of alantolactone and isoalantolactone was determined by HPLC was used with PDAD detector;the column was CAPCELL PAK MG C18 (4.6 mm×250 mm, 5μm);the mobile phase consisted of acetonitrile-0.4%phosphoric (58∶42);the flow rate was 1.0 mL/min;the detection wavelength was set at 225 nm;the column temperature was maintained at 30 ℃. Results The linear range of alantolactone was 0.083-0.517 μg (r=0.999 9), and isoalantolactone was 0.108-0.672 μg (r=0.999 9). The mean recovery of alantolactone was 97.95%, RSD=1.31%. The mean recovery of isoalantolactone was 97.69%, RSD=1.24%. Conclusion The method is accurate and simple in operation, which can be used to simultaneously determine contents of alantolactone and isoalantolactone in Sanwei Ganlusan.

AIM: To extract the effective composition from Radix Arnebiae seu Lithospermi and make it into the vagina effervescent tablet. It would be convenient and effective to treat the disease for the patients. METHODS : To sift the technology of extracting the effective composition by experiment and find out the prescription of the vagina effervescent tablet,its time of disintegration and the quantity of producing foam can accord with the principle of the vagina effervescent tablet in Chinese pharmacopoeia. RESULTS : The technology of extracting the effective composition and the prescription of the vagina effervescent tablet by experiment are practical. CONCLUSION : It is convenience for patients to take vagina effervescent tablet of Radix Arnebiae to treat their diseases

OBJECTIVE:To investigate the effect of Xuebijing injection on coagulation function and prognosis in patients with sepsis. METHODS:50 patients with sepsis were randomly divided into control group and observation group according to the hospi-talization sequence,with 25 cases in each group. Control group received conventional treatment,and observation group was addi-tionally given Xuebijing injection(50 ml added into 5% Glucose solution or 0.9% Sodium chloride solution 250 ml intravenously, bid) on the basis of conventional treatment. Treatment course lasted for 7 d. The coagulation function,APACHE Ⅱscore after 7 days of treatment and 28 d mortality were compared between 2 groups. RESULTS:After 7 d treatment,the coagulation indexes were improved significantly in 2 groups compared with before treatment,and the APACHEⅡscores were decreased significantly in both groups;the observation group were significantly better than the control group,with statistical significance (P<0.05). After followed up for 28 d,the mortality rate of 2 groups were 16% and 28%,there was no statistical significance (P>0.05). CON-CLUSIONS:Xuebijing injection can inhibit blood clotting activation,correct the coagulation disorders,and improve the sepsis se-verity.

ObjectiveTo assess the clinical value of ultrasound-guided percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) combined with portal vein tumor thrombosis (PVTT).MethodsNinety HCC patients with different type PVTT underwent ultrasound-guided PEI once or twice a week.The follow-up lasted 12 to 60 months,and the 1-,2-,3-,4- and 5-year survival rates were calculated.ResultsThe median survival time of HCC combined with PVTT patients treated with PEI was 12 months,and the 1-,2-,3-,4- and 5-year survival rates was 52.22％,23.33％,15.56％,12.22％ and 10.00％,respectively.The survival rate correlated significantly to the type of PVTT.The lower the type of PVTT was,the longer the patients lived.ConclusionUltrasound-guided PEI is a safe and effective method for the treatment of HCC combined with PVTT,and can prolong the survival time of HCC patients with low type PVTT.

Objective To assess the reliability and validity of the Chinese version of Multidimensional fatigue symptom inventory-short form(MFSI-SF).Methods The reliability and validity of the Chinese version MFSI-SF were assessed in a sample of 203 cancer patients.Statistical software was used to perform the analysis.Results The results showed moderate correlation between items and the total scale,the content validity index was 0.82,and exploratory factor analysis indicated five dimensions of the scale,the cumulative variance contribution was 56.65％.Confirmatory factor analysis showed moderate model fitting:x2/df=l.73,GFI=0.83,AGFI=0.79,NNFI=0.94,RMSEA=0.06,criterion validity was 0.585,and the Cronbach α of the total scale was 0.896.Conclusions The results demonstrated good convergent validity,it is suitable to evaluate fatigue status in Chinese cancer patients.

Purpose To evaluate the diagnostic value of diffusion weighted imaging with high b value in acute cerebral microinfarcts.Materials and Methods Conventional MRI and diffusion weighted imaging with standard b value (b=1000 s/mm2) and high b value (b=3000 s/mm2) were performed in the 7 patients with acute cerebral infarction,and all the images were evaluated.The signal to noise ration (SNR) and contrast to noise ration (CNR) were measured.Results Five patients were detected much more microinfarcts in high b value as HB group than that in standard b value as SB group.The SNR and CNR were significantly higher in high b value group than that in standard b value group (P＜0.05),but the apparent diffusion coefficient value showed no significant difference between the two groups (P＞0.05).Conclusion DWI with high b value could sensitively detect acute cerebral microinfarcts with high clinical value.
