OBJECTIVE:To provide reference for promoting the management of antibiotics in the hospitals. METHODS:Each 3 hospitals from county second grade class A general hospitals,municipal third grade class A general hospitals and provincial third grade hospitals(including 2 third grade class A general hospitals and one third grade special hospital)in Anhui province were select-ed and respectively included into group A,B,and C. By on-site survey mode,questionnaires were used to investigate and score the situation of antibiotics management in hospitals of 3 groups,and then analyzed statistically. RESULTS:Scoring rate (SR) of overall situation on antibiotics management were 65.33%,89.34% and 86.67% in group A,B and C respectively;group A was statistically significantly lower than group B and C (P<0.001). SR of basic situation indicator on antibiotics management were 90.46%,95.25% and 95.25% in group A,B and C,respectively and there was no statistically significant difference among 3 groups (P>0.05). SR of development indicator of antibiotics management were 58.33%,88.90% and 86.10%,respectively in group A,B and C;group A was significantly lower than group B and C (P<0.001). SR of information construction indicator of antibiotics management were 50.00%,83.33% and 77.79% respectively in group A,B and C;group A was significantly lower than group B and C (P≤0.001). SR of information construction indicator of antibiotics management in 3 groups were all signifi-cantly lower than SR of basic situation indicator(P<0.05). SR of development indicator of antibiotics management in group A and C were all significantly lower than SR of basic situation indicator(P<0.05). CONCLUSIONS:The antibiotics management of mu-nicipal third grade class A general hospital is equal to that of provincial third grade hospital,and that of county second grade class A general hospital is in relatively low level. Different levels of hospitals should further strengthen the related antibiotics manage-ment work and information construction,especially for county second grade class A general hospitals.

Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae. Among amino acids detected, natural amino acids accounted for a larger proportion, and those natural amino acids showed bitterness, slight bitterness, sourness (freshness), sweetness, slight sweetness, sourness (slight freshness).

OBJECTIVETo study TCM syndrome distribution laws in patients with coronary heart diseases (CHD) by epidemiological investigation.

METHODSA clinical survey was carried out in 319 inpatients with CHD, whose diagnosis was confirmed by coronary arteriography, in the authors' hospital from January 2004 to December 2004. The TCM syndrome distribution laws were analyzed, and the relationship of coronary arteriographic picture with TCM syndrome elements, common symptoms, pulse and tongue figures, as well as the correlation between syndrome typing and blood-lipid levels were analyzed, too.

RESULTSQi deficiency was the most popular syndrome in patients with CHD (87.1%), blood stasis syndrome and phlegm retention syndrome took the second place, accounting for 79.9% and 78.7% respectively. No significant difference was shown in comparison of tongue and pulse figures with the affected branches of coronary artery, the dark-pale tongue with white greasy fur and taut-slippery pulse being the dominance in patients. The blood-lipid levels in patients with various TCM syndrome types were similar, showing insignificant difference.

CONCLUSIONThe TCM pathogenesis of CHD takes qi deficiency as the core, blood stasis and phlegm retention as the important pathologic products.

Background and purpose:In recent years, epigenetics research has become a new direction of cancer research. A large number of results have shown that the abnormal changes of epigenetic modifications have close connection with cancer. Genome-wide epigenetic modifications have become new markers for cancer. This study aimed to investigate the methylation of the promoter ofDBC1 gene in cervical cancer tissues of Uyghur women in Xinjiang, to explore the correlation between the gene methylation and the infection of HPV, and to evaluate whether it can be used as a tool with high sensitivity and specificity for cervical cancer screening.Methods:This study detected the infection of HPV16, 18 in 43 normal cervical tissues, 35 cervical intraepithelial neoplasia tissues and 54 cervical cancer tissues using the polymerase chain reaction (PCR) method. The methylation of the promoter ofDBC1 gene in above-mentioned tissues was detected by the methylation-specific PCR method. The expression ofDBC1 at mRNA level was measured by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) in 10 methylation-negative normal cervical tissues and 10 methylation-positive cervical cancer tissues.Results:In normal cervical tissues, CIN tissues and cervical cancer tissues, the infection ratios of HPV16 were 18.6%, 34.3% and 68.5%, respectively; the infection ratios of HPV18 were 2.3%, 8.6% and 16.7%, respectively; and the methylation ratios ofDBC1 gene were 23.3%, 40.0%, 87.0%, respectively. In 79 high-grade squamous intraepithelial lesions (CINⅡ and Ⅲ) and cervical cancer tissues, 50 of 79 were infected with HPV16/18, while 29 of 79 were negative. The methylation ratio ofDBC1 gene was 88.0% in HPV16/18 infection positive group while the methylation ratio was 55.2% in negative group (P<0.05). The expression ofDBC1 gene at mRNA level in 10 methy- lation-positive cervical cancer tissues was significantly lower than that in the 10 methylation-negative normal cervical tissues (P<0.05).Conclusion:The methylation ofDBC1 gene may become a molecular marker to detect cervical cancer of Uyghur women in Xinjiang.DBC1 gene methylation combined with HPV16/18 infection test can be used to aid diagnosis of cervical cancer.

OBJECTIVETo explore anti-cancer effect and mechanism of green tea extract (GTE) in three human oral squamous carcinoma cell lines (CAL-27, SCC-25 and KB).

METHODSThe cell lines were in vitro cultured and its growth inhibition was detected by MTT. After screening most sensitive cell line, effect of GTE on CAL-27 cell cycle was analyzed by flow cytometry. The protein expression of GTE on CAL-27 cell strain was determined by protein chip technique. The protein expression of CDK4, CDK6, and p-PDK1 was verified by using Western blot.

RESULTSCompared with the control group, the inhibition rate on CAL-27 increased significantly after treated by 50, 100, 200, and 400 μg/mL GTE; the inhibition rate on KB increased after treated by 100, 200, and 400 μg/mL GTE; the inhibition rate on SCC-25 increased after treated by 25, 50, 100, 200, and 400 μg/mL GTE, all with statistical difference and in dose dependant manner (P < 0.01). Flow cytometric analysis showed that, when compared with the control group, 50 μg/mL GTE arrested CAL-27 cells in the G2/M phase (P < 0.05), and 100 μg/mL GTE arrested CAL-27 cells in the G2/M phase with concurrent decreased cells in the G0/G1 phase (P < 0.01). Totally 107 proteins were analyzed by protein chip technique. After treated by GTE, a total of 13 proteins significantly changed in CAL-27 cell line. Western blot showed that 25, 50, and 100 μg/mL GTE inhibited the expression of phopho-phosphoinositide-dependent protein kinase 1 (p-PDK1), cyclin-dependent kinase 4 (CDK4), and CDK6 of CAL-27 cell line with statistical difference (P < 0.05). The higher the drug concentration, the higher the inhibition rate (P < 0.05).

CONCLUSIONSGTE could inhibit the proliferation of different human oral squamous carcinoma cell lines. CAL-27 is a sensitive cell line. GTE significantly affected EGFR and Notch signal network, and influenced changes of cell cycle related protein expression levels through the aforesaid channels, resulting in cell cycle arrest in S and G2/M phases.
