[Influence of Steam Killenzyme Torrefaction on Quality of Camellia nitidissima Based on Multi-index Evaluation].

OBJECTIVE: To explore the influence of steam killenzyme torrefaction on the quality of Camellia nitidissima. METHODS: Based on the quality evaluation index, Camellia nitidissima was processed by steam killenzyme torrefaction and sun-dried. The contents of functional ingredients such as flavonoids, saponins, tea polyphenols, polysaccharides, amino acids, tea extracts, catechin and epicatechin were determined by HPLC and UV. Meanwhile, the antioxidant activity was determined by ABTS method, DPPH x assay, pyrogallol method and phenanthroline. RESULTS: Compared with the sun-dried sample, the total flavonoids, saponins and epicatechin content were decreased in varying degrees, catechin was not detected. CONCLUSION: The water soluble components content of Camellia nitidissima is increased, and antioxidant capacity is enhanced by processed using steam killenzyme torrefaction. By contrast, the alcohol soluble components and antioxidant capacity are decreased.

Effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis on the expression of gastric mucosal heat shock protein 70 in chronic atrophic gastritis patients / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.</p><p><b>METHODS</b>A total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.</p><p><b>RESULTS</b>The total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).</p><p><b>CONCLUSION</b>CDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.</p>
