Analysis of HUANG Feng's Medication Rules for Low Back Pain Based on Data Mining / 广州中医药大学学报

Objective To analyze the medication rules of Professor HUANG Feng for the treatment of low back pain using data mining methods.Methods The information of prescriptions for the effective cases of outpatients with low back pain treated by Professor HUANG Feng were collected and screened.Microsoft Excel 2019 was used to analyze the frequency of medication and the distribution of properties,flavors and meridian tropism of the drugs in the included prescription.IBM SPSS Modeler 18.0 was used for association rule analysis,and IBM Statistics 26.0 was used for cluster analysis.Results A total of 239 prescriptions and 75 Chinese medicines were included.There were 23 high-frequency Chinese medicines with the medication frequency being or over 20 times,and the top 10 Chinese medicines were Glycyrrhizae Radix et Rhizoma,vinegar-processed Corydalis Rhizoma,Cibotii Rhizoma,Atractylodis Macrocephalae Rhizoma,Zanthoxyli Radix,salt-processed Achyranthis Bidentatae Radix,Rehmanniae Radix,Dipsaci Radix,Coicis Semen,and Salviae Miltiorrhizae Radix et Rhizoma.The medicines were mainly warm in nature,and were sweet,bitter and pungent in flavor.Most of the drugs had the meridian tropism of liver,stomach and spleen meridians.Among the drug combinations obtained from association rule analysis with the top 20 highest support,vinegar-processed Corydalis Rhizoma,Cibotii Rhizoma,Atractylodis Macrocephalae Rhizoma and Zanthoxyli Radix were the core drugs.Cluster analysis yielded 6 clustering combinations.Conclusion For the treatment of low back pain,Professor HUANG Feng follows the principle of"treatment adapting to the climate,individuality,and environment"and"treating the root cause of the disease",usually adopts the drugs for activating blood,moving qi and relieving pain,nourishing the liver and kidney,and also uses the medicines for replenishing qi and strengthening the spleen.The ideas of HUANG Feng for the treatment of low back pain can be used as a reference for the clinical treatment.

Clinical and prognostic significance of preoperative serum CA153, CEA and TPS levels in patients with primary breast cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the clinical and prognostic values of preoperative serum CA153, CEA and TPS levels in patients with primary breast cancer.</p><p><b>METHODS</b>A total of 386 hospitalized patients with stage I ∼ IV breast cancer from Nov 1998 to Feb 2009 were followed up, and their clinicopathological data were analyzed retrospectively to determine the factors affecting their prognosis.</p><p><b>RESULTS</b>First, preoperative serum CA153 expression level was significantly associated with the age of onset and tumor size (P < 0.05), the expression of serum CEA was correlated with tumor size (P < 0.05), and the expression of serum tissue polypeptide specific antigen (TPS) was correlated with tumor size and lymph node metastases (P < 0.05). Second, the overall survival was significantly shorter among patients with elevated serum CA153, CEA or TPS, respectively (P < 0.05 for overall). Finally, multivariate Cox regression analysis indicated that estrogen receptor status (ER) and elevated preoperative values of CA 153 are independent prognostic factors for overall survival (P < 0.05), and CA 153 is a risk factor but estrogen receptor status is a protective factor for overall survival.</p><p><b>CONCLUSIONS</b>Higher preoperative expression of serum CA153, CEA or TPS is closely correlated with clinicopathological characteristics and overall survival. The prognosis is poorer in primary breast cancer patients with higher CA15-3 expression level, and pre-treatment CA153 expression level can be used as an independent prognostic parameter in patients with primarily breast cancer.</p>

Clinical research of AFP variant with microcentrifugalcolumn method and crossed affinity immunoelectrophoresis autoradiography method / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To compare the clinical value of microcentrifugalcolumn method with crossed affinity immunoelectrophoresis autoradiography method for the measurement of alpha-fetoprotein variant (AFP-L3) in differentiation of benign and malignant liver.</p><p><b>METHODS</b>Serum AFP-L3 variants in 102 primary hepatocellular carcinoma patients and 41 chronic and cirrhosis patients were separated by microcentrifugalcolumn method and crossed affinity immunoelectrophoresis autoradiography method and the clinical value of both method were compared.</p><p><b>RESULTS</b>In 102 primary hepatocellular carcinoma patients, the sensitivity of AFP-L3 was 79.4% and 91.2% respectively, in 41 chronic and cirrhosis patients. The specificity of AFP-L3 was 70.7% and 29.3% respectively. The diagnostic accuracy was 76.9% and 73.4% respectively. The area in the ROC curve was 0.791 and 0.758 respectively. In the 4 primary hepatocellular carcinoma patients with lower AFP-L3, the AFP-L3 was positive by useing microcentrifugalcolumn method, but none of AFP-L3 were found by useing crossed affinity immunoelectrophoresis autoradiography method.</p><p><b>CONCLUSION</b>The micro centrifugalcolumn method is more simple and rapid, it may be more useful in differentiation of benign and malignant liver than traditional crossed affinity immunoelectrophoresis autoradiography method.</p>
