OBJECTIVE:To optimize the extraction technology of polysaccharides from Gossypium herbaceum L. by pectinase hydrolysis. METHODS:Polysaccharides were extracted from G. herbaceum L. by pectinase hydrolysis combined with traditional hot water extraction. With the extraction rate of polysaccharides as the evaluated index,single factor test and orthogonal design were applied to investigate the effects of 4 factors including enzymolysis temperature,enzymolysis time,the amount of enzyme and pH value on polysaccharides extraction rate,and verification tests were conducted. RESULTS:The optimal extraction technolo-gy was as follows as enzymolysis temperature of 40 ℃,enzymolysis time of 150 min,enzyme accounting for 2.0%,pH value for enzymolysis of 4.6. Under the above conditions,the average extraction rate of polysaccharides from G. herbaceum L. was 2.474%(RSD=3.34%,n=5). CONCLUSIONS:Pectinase hydrolysis is an effective method to extract polysaccharides from G. herbace-um L.. The optimal extraction technology is reasonable and feasible.

Objective To examine expression levels of autophagy gene pULK and PI3KC3 and to explore their correla?tion with non-small cell lung cancer (NSCLC). Methods A total of 77 samples of surgical resection from NSCLC speci? mens (including 31 cases of squamous cell carcinoma, 31 cases of adenocarcinoma and 15 cases of large cell undifferentiated carcinoma) and 21 samples of same normal lung tissue were randomly selected. Expressions of pULK and PI3KC3 in lung tissues were assessed by immunohistochemistry and Western blot. All dates were analyzed using SPSS13.0 statistical pack?age. Results Immunohistochemistry indicated that pULK and PI3KC3 localized into the cytoplasm. The expression levels of pULK and PI3KC3 are significantly lower in patient with NSCLC than those in peri-tumor tissue (35.1%vs 81.0%, 40.3%vs 76.2%respectively, P<0.01) . Immunohistochemistry and Western bolt analysis confirmed that pULK and PI3KC3 ex?pressions were significantly down-regulated (P<0.01) in patients with low grade cellular differentiation, metastasis of lymph node, or stageⅢandⅣ. And expression levels of pULK and PI3KC3 in NSCLC did not differ significantly with ages, gen?der, tumor size and pathological type. Correlation analysis showed that the expression of PI3KC3 was positively correlated with pULK. Conclusion pULK and PI3KC3 expressions were lower in NSCLC than those in normal lung tissue group. The expression levels of pULK and PI3KC3 in NSCLC were correlated with patient's clinical stage, differentiation grade, lymph node metastasis but were unrelated with age, gender, histological type and size.

Objective To evaluate the clinical efficacy of 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) in the treatment of condyloma acuminatum. Methods Thirty-six cases of condyloma acuminatum were treated with ALA-PDT. Results After the treatment, 33 (91.67%) patients were cured, 35 (97.22%) improved. Relapse occurred in 3 (8.33%) patients. Side effects were noted in 2 (5.56%) patients. Conclusions ALA-PDT is a relatively simple, effective and safe treatment with a lower recurrence rate for condyloma acuminatum, especially for small skin lesions or lesions at specific area. However, the high expense required for multiple treatments with ALA-PDT may restrict its application.
