CY (Extract of Paeonia lactiflora Pall. ) was found to have significant therapeutic effect ou skin lesions of HSY-1 infection in guinea pigs at 5mg/ml concentration. Inhibition effet on the development of skin lesions was similar to ribavirin, with recoyery 4 days after treatment. At 10 or 2.5mg/ml recovcry was also achieved after 6 or 7 days respectively. The results showed that CY is an effective anti-HSV-1 drug.

Objective To explore the clinical value of combined detection of lysophosphatidic acid(LPA),tumor-specific growth factor(TSGF)and carbohydrate antigen 1 9-9(CA1 9-9)in the diagnosis of non-small cell lung cancer(NSCLC).Methods The ser-um levels of LPA,TSGF and CA1 9-9 in 97 cases of patients with NSCLC(NSCLC group),43 cases of patients with benign lung disease(benign lung disease group)and 50 cases of healthy individuals(healthy control group)were detected,and diagnostic value of combined detection of these three tumor makers in the diagnosis of NSCLC was analysed.Results Serum levels of LPA,TSGF and CA1 9-9 in the NSCLC group were significantly higher than those in the benign lung disease group and healthy control group,had statistically significant differences(P <0.05).The sensitivity and specificity of combined detection of LPA,TSGF and CA1 9-9 was 68.63% and 37.1 7% respectively,and the sensitivity was higher than that of single detection and combined detection of any two of the three indicators.Conclusion Combined detection of tumor markers can improve the sensitivity in the diagnosis of NSCLC, which could provide reliable laboratory references for diagnosing NSCLC.

Objective To detect the expressions of two protein factors hypoxia-inducible factor (HIF)-1α and Helicobacter pylori (Hp) in gastric cancer in Mongolian and Han two nationalities respectively,and to explore the relationship of HIF-1α and Hp in the development of gastric cancer.Methods A modified Warthin-Starry (W-S) silver staining method was used to detect Hp infection in 27 Mongolian patients with gastric cancer and 30 Han patients with gastric cancer.Immunohistochemical (S-P) method and reverse transcription polymerase chain reaction (RT-PCR) method were used to detect protein and mRNA expressions of HIF-1α in cancer tissue,paracancerous tissue and normal tissue samples.The relationship of HIF-1α protein and Hp expression was analyzed between gastric carcinoma tissue samples of Mongolian patient group and Han patient group.Results Hp infection rates were 81.5％ (22/27) and 66.7％ (20/30) in Mongolian and Han patients with gastric cancer.The difference in infection rate was not statistically significant between two groups of patients (~=1.608,P ＞ 0.05).The positive expression levels of HIF-1α protein were 62.96％ (17/27) and 70.00％ (21/30) in gastric cancer tissue samples of Mongolian and Han groups.The relative expression levels of HIF-1α mRNA were 0.891 4±0.075 0 and 0.907 4±0.065 5.There was no significant difference in the HIF-1 α mRNA expression between the two nationalities.No positive expressions of HIF-1α protein and mRNA were found in paracancerous tissue and normal tissue samples.There was a positive correlation in the positive expression of HIF-1α protein and Hp infection in gastric cancer tissue samples of Mongolian and Han patient groups (r,=0.424 and 0.617,P ＜ 0.05).Conclusion HIF-1α and Hp are pathogenic factors of gastric cancer.Hp and HIF-1α may promote the occurrence of gastric cancer together.The pathogenic mechanism of HIF-1α and Hp in gastric cancer may be the same for Mongolian and Han patients.

Fifteen patients with spasticity were treated by phenol blocks. The results are satisfactory.Phenol blocks has the advantages of high selectivity,few side-effects and low cost. The anthor recommends that phenol blocks could be used in clinical antispasticity treatment.

OBJECTIVE: To investigate the histopathologic changes of ethmoid bone and its correlation with clinical types of chronic rhinosinusitis (CRS). METHOD: All ethmoid bones and mucosa from 180 patients with CRS after endoscopic sinus surgery were collected for histopathologic detection with HE staining. The number and the rate of cases were counted according to different histopathologic types. To analyze the correlation between ethmoid bones and clinical types of CRS, mucosal pathologic change, the CT-scanning types of sinusitis, the course of disease as well as operational history. RESULT: The ethmoid bone of all patients had varying degrees of histopathologic changes. There were 5 cases (2.78%) in stage I, 38 cases (21.11%) in stage II, 71 cases (39.44%) in stage III, and 66 cases (36.67%) in stage NIV. The histopathologic changes of ethmoid bone varied in different clinical types. In type I, there were 5 cases (8.33%) in stage I, 33 cases (55.00%) in stage II, 15 cases (25.00%) in stage III, and 7 cases (11.67%) in stage NV. In type I, there were 5 cases (8.33%) in stage II, 37 cases (61.67%) in stage mI, and 18 cases (30.00%) in stage NV. In type III, there were 19 cases (31.67%) in stage III, and 41 cases (68.33%) in stage NV. All histopathologic changes of ethmoid bone were statistically correlated (P < 0.01) with clinical types of CRS, pathologic mucosal change, the CT-scanning types of sinusitis, the course of disease as well as operational history. CONCLUSION Almost all patients with CRS manifest different-degrees of histopathologic changes, which are correlated with the clinical types of CRS, pathologic mucosal change, the CT-scanning types, the course of disease as well as operational history.
