Study on discrimination mode of cold and hot properties of traditional Chinese medicines based on biological effects / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the effect of cold or hot properties of traditional Chinese medicines (TCM) on biological effect indexes, and analyze the contribution of variables on cold or hot properties, in order to preliminarily establish the discrimination mode for the biological effects of cold or hot properties.</p><p><b>METHOD</b>Rats were randomly divided into the blank control group, cold TCM groups (Coptidis Rhizoma, Scutellariae Radix, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix and Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex and Evodiae Fructus), and orally administered with 10 mL x kg(-1) of corresponding TCM water decoctions for 30 d, twice a day. Altogether 53 biological effect indexes correlated to cold or hot properties of traditional Chinese medicines were founded by searching literatures. The data warehouse were established by using data-mining software Clementine12.0. Data of the blank control group, cold TCM groups (Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix, Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex) were selected into a training set. C5.0 algorithm and C&R classification and regression algorithm were adopted to define the importance of variable, create the decision trees, and test hot or cold properties of Evodiae Fructus and Scutellariae Radix.</p><p><b>RESULT</b>According to C&R classification and regression algorithm, SDH activity of livers was the most important hot or cold property, with the significance closed to 30%. It was followed by triglyceride, liver Na' -K' -ATPase enzyme, muscle glycogen and platelet distribution width, with the accuracy up to 97.39% in models. C5.0 algorithm showed that liver SDH activity was the most important hot or cold property, with the significance closed to 40%. It was followed by triglyceride, GOT, muscle glycogen and liver Na(+)-K(+)-ATPase enzyme, with the accuracy up to 98.26% in models. The possibilities that Evodiae Fructus is in hot property and Scutellariae Radix is in cold property were 100. 00% and 77.78% by using both C&R classification and regression algorithm and C5.0 algorithm.</p><p><b>CONCLUSION</b>The SDH activity of liver is the most important biological effect index to distinguish cold and hot properties of TCMs. The discrimination pathway or mode of cold and hot properties is closely related to energy metabolism.</p>

Clinical efficacy and safety of sublingual immunotherapy using standardized Dermatophagoides farinae extract for children with combined allergic rhinitis and asthma syndrome / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To study the clinical efficacy of sublingual immunotherapy using standardized Dermatophagoides farinae extract for children with combined allergic rhinitis and asthma syndrome.</p><p><b>METHODS</b>Fifty-two children, from 4 to 14 years of age, with mite-sensitive combined allergic rhinitis and asthma syndrome were treated sublingually with standardized Dermatophagoides farinae extract. The clinical efficacy was evaluated by monthly follow-up visits. After treatment for 1 or 2 years using the standardized Dermatophagoides farinae extract, the asthma and rhinitis symptom scores, medication scores and adverse reactions before and after treatment were evaluated. SPSS 17.0 software was used to analyze the data.</p><p><b>RESULTS</b>The allergic asthma symptom scores before treatment during the day were 3.22 ± 0.66 and at night 2.05 ± 0.57. After 1 year of treatment, the day and night scores (1.68 ± 0.61, 0.94 ± 0.32) respectively, were decreased significantly (q values were 15.25 and 13.78 respectively, all P < 0.01). After 2 years of treatment, the scores (0.61 ± 0.28, 0.43 ± 0.13) were also decreased significantly (q values were 10.29 and 6.07 respectively, all P < 0.01). The allergic rhinitis symptom scores and medication scores were 2.34 ± 0.59 and 3.09 ± 1.01 respectively before treatment and 1.21 ± 0.46 and 1.89 ± 0.64 after 1 year of treatment. The differences were significant (q values were 15.48 and 18.61 respectively, all P < 0.01). The allergic rhinitis symptom scores and medication scores were 1.02 ± 0.37 and 1.49 ± 0.38 after 2 years of treatment. There was no significant difference between 2 years of treatment and 1 year of treatment (q values were 2.53 and 2.78 respectively, all P > 0.05). There were no severe adverse events during the treatment, except for mild mouth cavity discomfort.</p><p><b>CONCLUSIONS</b>Sublingual immunotherapy using standardized Dermatophagoides farinae extract is safe and effective in the treatment of children with combined allergic rhinitis and asthma syndrome.</p>

Microneurosurgical resection of third ventricle tumors involving the lateral ventricle through the transcallosal interforniceal approach / 中华神经医学杂志

Obiective To evaluate the clinical efficacy of microsurgical resection of third ventricle tumors involving the lateral ventricle through the transcallosal interfomiceai approach. Methods From October 2005 to April 2009, 12 patients with third ventricle tumors involving the lateral ventricle received microsurgical resection of the tumors through the transcollasal interfomiceal approach. Results The tumors were totally removed in 4 cases, subtotally in 3 cases and partially in 5 cases without any fatal consequences. Conclusion This approach is safe and effective for removing third ventricle tumors involving the lateral ventricle by accessing the tumor through the anatomical space in the brain, and allows clear exposure of the operative field and causes minimal invasiveness of the surrounding structure with reduced complications.
