[Summary and analysis of safety warning on clinical application of anti-cold Chinese patent medicine preparations].

In China, many surveys have shown that most people do not have a correct understanding about cold and administration of anti-cold Chinese patent medicine preparations. The author conducted a systematic summary and analysis on the actual application of anti-cold Chinese patent medicine preparations as well as the warning on safe application of anti-cold Chinese patent medicine preparations in Clinical Medication Information of China Pharmacopoeia, in the expectation of reducing the blind application of anti-cold Chinese patent medicine preparations and providing traditional Chinese medicine pharmacists new ideas in monitoring the safe application of exterior syndrome-relieving Chinese patent medicine preparations.

[DNA extraction and sex determination for human teeth dated 3000 years ago unearthed in Xi'an].

OBJECTIVE: To extracted DNA from ancient human teeth dated 3000 years ago unearthed in Xi'an and determine the genders for the individuals. METHODS: Thirty five ancient human teeth were studied. A 'Reverse-root-canal' technique and a Chelex-100 solution were used to extract the DNA. Specific primers for Amelogenin gene were designed for PCR amplification. RESULTS: Genomic DNA was successfully extracted from 30 samples, for which 8 were determined to be males and 22 were females. CONCLUSION: The 'Reverse-root-canal' technique may be used for extracting DNA from ancient human teeth. Genetics method can supplement physical anthropology for determination of sex for ancient samples.

[Study on the correlation between the inflammatory factors in the serum and the induced sputum and the hypothalamic-pituitary-adrenal axis function in advanced lung adenocarcinoma of different syndromes].

OBJECTIVE: To study the correlation between the inflammatory factors in the serum and the induced sputum and the hypothalamic-pituitary-adrenal (HPA) axis function in advanced lung adenocarcinoma patients of different syndromes. METHODS: Totally 71 patients with advanced lung adenocarcinoma were assigned to three groups according to syndrome differentiation, i.e., Shen-yang deficiency (SYD) group (28 cases), Fei-qi deficiency (FQD) group (23 cases), and yin deficiency fire excess (YDFE) group (20 cases). Another 41 healthy subjects were enrolled as the normal control group. Sputum was induced and blood samples were collected for measurement of cytokines including tumor necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGF-beta), interleukin-6 (IL-6), and interferon gamma (INF-gamma). The cytokine assay was performed using Bio-Plex Pro multi assay technology. 24-h collection of urine was performed and salivary samples of the diurnal rhythm profiles [including urinary free cortisol (UFC), urinary 17-hydroxycorticosteroids (17-OH), urinary 17-ketosteroid (17-KS), and cortisol in the serum and saliva] were obtained for assessment of the HPA axis activity. RESULTS: A higher level of serum IL-6 and a lower level of 24-h UFC and 17-OH were found in the SYD group (P < 0.05). The urinary 17-KS was obviously lower in the SYD group than in the normal control group and the YDEE group (P < 0.05). Compared with the FQD group and the normal control group, a higher serum level of TNF-alpha and a lower level of IFN-gamma were found in the SYD group and the YDFE group (P < 0.05). The TNF-alpha and TGF-beta levels in the induced sputum obviously increased in the SYD group (P < 0.05). The IFN-gamma level in the induced sputum obviously decreased in the YDFE group (P < 0.05). The serum and salivary cortisol obviously decreased from 8: 00 am to 8:00 am the next morning in the SYD group (P < 0.05). The serum cortisol level was negatively correlated with serum TNF-alpha (r = -0.26, P = 0.03) and serum IL-6 (r = -0.25, P = 0.03). The salivary cortisol level was negatively correlated with IL-6 in the induced sputum (r = -0.29, P = 0.02). The serum IFN-gamma was positively correlated with urinary 17-OH (r = 0.21, P = 0.03). CONCLUSIONS: The inflammatory factors of advanced lung adenocarcinoma patients of SYD syndrome were up-regulated, with the most obvious decreased or disarranged HPA axis functions. The levels of IL-6, TNF-alpha, and IFN-gamma were closely correlated with the HPA axis functions. The transformation from qi deficiency, yin deficiency to Shen-yang deficiency existed in lung adenocarcinoma patients. The levels of IL-6, TNF-alpha, and IFN-gamma in the serum and the induced sputum, as well as the HPA axis functions are important indices for microscopic syndrome typing of lung adenocarcinoma.

[Effects of bushen huoxue recipe on urinary levels of albumin, IL-6, TGF-beta1 and MCP-1 in chronic nephritis patients of shen-deficiency blood-stasis syndrome].

OBJECTIVE: To observe the effect of Bushen Huoxue Recipe (BSHXR, a Chinese medicine recipe for Shen reinforcing and blood circulation activating) on the levels of urinary albumin, interleukin-6 (IL-6), transforming growth factor-beta1 (TGF-beta1), and monocyte chemotactic protein-1 (MCP-1) in chronic nephritis patients of Shen-deficiency blood-stasis syndrome. METHODS: Forty-five patients were blocking assigned randomly to two groups, fifteen patients in the control group and thirty in the treatment group. All orally took Monopril 10 mg, once daily. But BSHXR was given additionally to patients in the treatment group after decocting,one dose per day (taken in two times). The treatment course for both groups was eight weeks. Besides, a normal control group consisting of six healthy subjects from health examination of Shuguang Hospital was set up. The 24-h urinary albumin and contents of TGF-beta1, IL-6 and MCP-1 in urine of all subjects were observed. RESULTS: Compared with before treatment the 24-h urinary albumin was obviously reduced in the treatment group, showing significant difference (P<0.01). The urinary 24-h albumin decreased in the control group, with statistical significance (P<0.05). Statistical difference existed between the treatment group and the control group after treatment (P<0.01). Compared with before treatment, urinary levels of IL-6, TGF-beta1, and MCP-1 were all down-regulated in the treatment group and the control group after treatment (P<0.01), and the decreasing of IL-6 and TGF-beta1, levels was more significant in the treatment group statistically (P<0.05). CONCLUSIONS: BSHXR could attenuate the albuminuria in patients of chronic nephritis. Its mechanism might be possibly correlated with its down-regulation of IL-6, TGF-beta1, and MCP-1 levels.

[Effect of Bushen Huoxue recipe on the state of extracellular matrix in glomerulosclerosis rats model].

OBJECTIVE: To investigate the effect and acting mechanism of Bushen Huoxue Recipe (BHR) on the state of extracellular matrix in glomerulosclerosis (GS) rats model. METHODS: GS rat model was established by unilateral nephrectomy and adriamycin injection. Model rats were randomly divided into 4 groups: the normal control group, the model group, the test group treated by BHR, and the positive control group treated with fosinopril sodium, with 11 rats in each group. The 24 h urinary protein and renal function of rats were observed, the contents of matrix metalloproteinase 1 (MMP-1), tissue inhibitor of metalloproteinase 1 (TIMP-1) in renal tissue and transforming growth factor-beta1 (TGF-beta1) in blood plasma, and renal tissue were detected. RESULTS: Compared with those in the normal control group, 24 h urinary protein was increased and renal function was deprived in the model group; TIMP-1 expression increased, MMP1 expression decreased in renal tissue of rats in the model group, showing statistical difference between groups (P < 0.05). As compared with the model group, the abnormal changes of TIMP-1 and MMP1 expressions were ameliorated in the two groups treated either by BHR or fosinopril (P < 0.05). The content of TGF-beta1 in the model group, either in blood or in renal tissue, was significantly higher than those in the normal control group respectively (P < 0.01), showing no significant change after BHR treatment. CONCLUSION: The protective effect of BHR on renal function in rats with GS is possibly by way of influencing expressions of TGF-beta1, TIMP-1 and MMP1 to regulate the state of extracellular matrix and lessen the matrix aggregation.
