OBJECTIVETo research the distribution characteristics of Chinese medicine (CM) syndrome and syndrome elements of chronic fatigue syndrome (CFS) by analyzing literature in recent 20 years.
METHODSRelevant literature on treating CFS by syndrome differentiation of CM at home were retrieved by computer and manual ways. Database were established by using EpiData 3.1 to conduct frequency analysis of syndrome and syndrome elements.
RESULTSThe most common clinical syndromes were Xin-Pi deficiency syndrome, Gan stagnation Pi deficiency syndrome, Gan-Shen yin deficiency syndrome, Gan qi stagnation syndrome, and Pi-Wei qi deficiency syndrome. Disease locations were sequenced as Pi, Gan, Shen, and Xin. The clinical pathogenesis of CFS was characterized by deficiency of vital energy, complicated with intermingled excess and deficiency. Asthenia of healthy energy was mainly manifested as qi deficiency, blood deficiency, and yin deficiency, while excess of sthenia was mainly manifested as qi stagnation, phlegm dampness, and static blood.
CONCLUSIONSResearch of CM syndrome starting from syndrome elements can better unify and standardize clinical syndrome differentiation. Results of literature analysis can provide reference for further studies.

OBJECTIVES: The purpose of this study was to compare the oral antimicrobial effects of seven different mouthwashes available in Korea. METHODS: To examine the antimicrobial effects of the seven mouthwashes, their minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) were determined using broth microdilution methods. Streptococcus mutans ATCC 25175, Lactobacillus acidophilus ATCC 4355, Candida albicans KCTC 7270, and Porphyromonas gingivalis ATCC 33277 were used in this experiment. S. mutans and P. gingivalis were examined using a scanning electron microscope (SEM), after treatment with the mouthwashes containing cetylpyridinium chloride (CPC). RESULTS: Mouthwashes containing CPC had lower MIC and MBC values against the four microorganisms. Their bactericidal effects were concentration-dependent. S. mutans and C. albicans were highly sensitive to the concentration of CPC in the mouthwashes. According to the SEM observation, the treatment of bacteria with mouthwashes containing CPC, changed the cell surface texture of S. mutans and P. gingivalis. CONCLUSIONS: Mouthwashes containing CPC showed relatively lower MIC and MBC values under the same conditions against the four microorganisms used in this study.

OBJECTIVES: The purpose of this study was to provide photodynamic bactericidal effect against Enterococcus faecalis by erythrosine concentrations and LED irradiation times. METHODS: Erythrosine was used as a photosensitizer and green LED (3 Watt, 520-530 nm) was used as light source. E. faecalis ATCC 1943 and E. faecalis ATCC 29212 were used in this study. Approximately 10(5) CFU of bacteria were added in wells of a 96-well microtitration plate. For examining the effects of concentrations of erythrosine, 0, 0.625, 1.25, 2.5, 5, and 10 microM of erythrosine were added in wells containing bacteria. The irradiation time with LED was 30 sec. In another set of experiment, the effect of irradiation time for killing of bacteria was investigated by increasing irradiation time from 0 to 30 s with 10 microM of erythrosine final concentration. After irradiation, each sample was serially diluted with PBS and 50 microl of diluents was spread on duplicate blood agar plates. The plates were incubated for 72 h at 37degrees C under aerobic conditions and the number of CFU was determined. The experiments were repeated four times. The results were analyzed using one-way ANOVA, and Tukey's multiple comparison at a significance level of 0.05. RESULTS: When the erythrosine concentrations were more than 2.5 microM, E. faecalis ATCC 29212 was significantly decreased (P<0.05). The more erythrosine concentrations increased, the more E. faecalis ATCC 1943 decreased statistically significantly (P<0.05). In another set of experiment, when LED irradiation time was more than 20 s, E. faecalis ATCC 1943 decreased significantly (P<0.05), and if the irradiation times was more than 5 s, E. faecalis ATCC 29212 decreased significantly (P<0.05). CONCLUSIONS: PDT using erythrosine and green LED was found to be an effective method in killing E. faecalis.

OBJECTIVETo investigate the protective action of Epimedium against chemotherapy-induced damage to rat epididymides.
METHODSFifty 60-day-old male rats were divided into a control, a model and a treatment group. Procarbazine was injected into the abdominal cavity of the model rats at the dose of 30 mg/(kg x d). In addition to procarbazine, Epimedium was given intragastrically to the treatment group. The changes in the ultrastructure of the epididymis were observed after 10 and 20 days.
RESULTSElectron microscopy showed that the chemotherapy-induced damages to the epididymal epithelia mainly included cell swelling, local cavitation of mitochondria, tumor-like change in nucleoli, agglutination of marginal translocation of heterochromatin and cell apoptosis. The damage to the epithelial ultrastructure was slight in the treatment group as compared with the model rats. Chemotherapy significantly affected sperm concentration, sperm viability and sialic acid (SA), which were (15.59 +/- 4.01) x 10(6)/ml, (76.71 +/- 10.11)% and (19.38 +/- 9.34) g/mg prot in the model group in comparison with (10.63 +/- 3.82) x 10(6)/ml (P < 0.01), (60.03 +/- 7.54)% (P < 0.01) and (13.62 +/- 7.81) g/g prot (P < 0.05) in the control. Epimedium significantly increased sperm viability in the treatment group (60.03 +/- 7.54)% as compared with the model rats (69.90 +/- 12.58)% (P < 0.05).
CONCLUSIONEpimedium can lessen chemotherapy-induced damage to the epididymis and protect the reproductive function of rats.

The aim of this study was to evaluate the therapeutic effects and adverse reactions of fludarabine-based regimen for patients with chronic lymphocytic leukemia(CLL).18 patients with CLL were treated with F regimen [fludarabine 30 mg/(m(2)·d) intravenously for 3 d, repeatedly every 28 days]. 22 patients were treated with FC regimen [fludarabine 25 mg/(m(2)·d) plus cyclophosphamide 250 mg/(m(2)·d) intravenously for 3 d, repeatedly every 28 days]. The results showed that the rate of complete remission (CR), partial remission (PR) and overall remission (OR) reached 16.7%, 61.1% and 77.8% in the F regimen groups and 59.1%, 40.9% and 100% in the FC regimen groups (P < 0.05, P > 0.05 and P > 0.05), respectively. FC regimen resulted in significantly higher CR rate than that in single-agent fludarabine regimen. The main adverse reactions were myelosuppression and immunosuppression. No significant differences were found between the two regimens. FC regimen did not increase the rate of severe infections. It is concluded that FC regimen can give higher CR rate as compared with F regimen, fludarabine-based regimens is effective and safe first-line regimen for patients with CLL.
