RESUMEN
This article summarized Professor GUAN Guo-Hua's clinical experience in treating central serous chorioretinopathy(CSC)in Lingnan area.Based on the theory of"macula due to the spleen dysfunction",and by taking the geographical and climatic characteristics of Lingnan area as well as the body constitutional features of Lingnan residents into account,Professor GUAN Guo-Hua proposed that spleen deficiency leading to damp encumbrance was the fundamental pathogenesis of CSC in Lingnan area,and liver and kidney were gradually affected in the middle and late stages of CSC,which finally resulted into blood stasis and water retention.For the treatment of initial attack of CSC,the focus was on treating the spleen,and Erchen Decoction was adopted as the basic prescription for modified application to strengthen the spleen and drain dampness;for the treatment of CSC in the middle and late stages,the emphasis was on simultaneous treatment of the liver,spleen and kidney as well as blood and water,and Zhujing Pills and Wuling Powder were adopted as the basic prescriptions for nourishing the liver and kidney and for strengthening the spleen,activating blood and promoting urination.The treatment of the spleen is advocated throughout the whole treatment process,and the medication of drugs should be modified based on syndrome differentiation and according to the specific conditions,thus to achieve significant results.
RESUMEN
Objective To summarize the prescription and medication rules for the treatment of diabetes mellitus by contemporary Lingnan famous Chinese medical practitioners through data mining analysis.Methods The literature on treating diabetes mellitus by contemporary Lingnan famous Chinese medical practitioners were retrieved from the databases of CNKI,Wanfang and VIP,and the collections of clinical experience and medical cases of contemporary Lingnan famous practitioners were also reviewed to screen the relevant medical records of diabetes mellitus treated by Lingnan famous practitioners.The information of Chinese medicine prescriptions for diabetes mellitus in the medical records was input to Excel to establish a database,and then the frequency analysis was performed in terms of the nature,flavors and meridian tropism,therapeutic-action classification of the Chinese herbal medicines and traditional Chinese medicine(TCM)syndrome types.Moreover,the association rule analysis and cluster analysis were carried out using IBM SPSS Modeler 18.0 and SPSS Statistics 26.0.Results A total of 62 medical records of diabetes mellitus treated by the 24 contemporary Lingnan famous Chinese medical practitioners such as DENG Tie-Tao,LIU Shi-Chang,XIONG Man-Qi,LI Sai-Mei,ZHU Zhang-Zhi,LIU Min,and FAN Guan-Ji were screened out for the analysis.And a total of 101 prescriptions involving 210 Chinese herbal medicines were included.There were 29 commonly-used Chinese medicines with a frequency being or more than 15 times,and they were Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Astragali Radix,Bupleuri Radix,Puerariae Lobatae Radix,Poria,Atractylodis Macrocephalae Rhizoma,Codonopsis Radix,Scutellariae Radix,etc.According to the therapeutic action,the Chinese medicines were mainly classified into the categories of drugs for supplementing the deficiency,drugs for clearing heat,and drugs for dispelling wind-damp.The primary syndrome types were syndrome of deficiency of both spleen and kidney and syndrome of liver stagnation and spleen deficiency,and the syndromes were usually complicated with the syndrome elements of qi deficiency,yin deficiency,yang deficiency,cold-damp,phlegm-damp,and damp-heat.The association rule analysis yielded 28 core drug combinations consisting of 2-4 herbs,and the cluster analysis yielded 5 new candidate prescriptions,which were mainly derived from the modification of classical formulas such as Xiao Chaihu Decoction,Fuzi Lizhong Decoction,Yuquan Pills plus Zengye Decoction,and Zuogui Pills.Conclusion For the treatment of diabetes mellitus,contemporary Lingnan famous Chinese medical practitioners primarily adopt the methods of invigorating spleen and warming kidney,and soothing liver,draining dampness and resolving turbidity,which has more distinctive regional characteristics of Lingnan and can provide a reference for syndrome differentiation and treatment of diabetes mellitus in the Lingnan area.
RESUMEN
The climate in the Lingnan area south China is characterized by high temperature and rainy days， and in terms of the eating habits， the local people are more addicted to raw， cold and savory food， all of which make Lingnan people prone to a constitution of upper heat and lower cold， and pathological manifestations of upper heat and lower cold. It is believed that the main pathogenesis of hyperthyroidism in Lingnan area is the upper heat and the lower cold， manifested as spleen yang deficiency and stomach fire excess， or kidney water depletion and heart fire hyperactivity， leading to upper heat and lower cold syndrome caused by disharmony of yin and yang and abnormal ascending and descending. Therefore， spleen cold and stomach heat and disharmony between the heart and the kidney are the main syndromes of hyperthyroidism in Lingnan area. Modified Huanglian Decoction （黄连汤） is commonly used. Additionally， for spleen cold and stomach heat syndrome， Fushen （Sclerotium Poriae Pararadicis） and Baizhu （Rhizoma Atractylodis Macrocephalae） can be added to supplement spleen and stomach， thereby treating both the root and the branch. In terms of the disharmony between the heart and the kidney syndrome， Muli （Concha Ostreae） is usually added to subdue yang and supplement yin， together with Wuweizi （Fructus Schisandrae Chinensis） to supplement kidney and calm heart and Shashen （Radix Adenophorae seu Glehniae） to nourish yin and engender liquid， thereby enriching kidney-water and moistening heart-yin. Modification of the formulas is suggested in accordance with the syndromes to achieve a better effect.

RESUMEN
Objective To investigate the awareness of osteoporosis and its influential factors in middle-aged and older people. Methods By using self-designed questionnaire, 354 middle-aged and old people were investigated as to their awarness of osteoporosis in Chajiao street community in Guangzhou. Among them, 58 people were measured the bone density in the calcaneal bone by Ultrasound. Results The average score of the questionnaire was 9.46 ± 5.13, and the accuracy was 39.4%. In the diagnosis and treatment, the accuracy was just 17.8%. The diet (the accuracy in 54%) and sport (the accuracy in 50.3%) were good. The statistical analyses showed the linear relationship between the T value of bone density and the age (P = 0.021), between the T value and the score (P = 0.047). Wilcoxon rank sum test found that the T value between female and male was significantly different (Z = -3.749, P < 0.000). With multiple linear regression analysis, the T value had a linear correlation with the score (F = 4.224, P = 0.045) positively. Conclusions Currently, the awareness of osteoporosis in the middle-aged and old people was inadequate. To better prevent osteoporosis, the propogation of knowledge and guidance provided by clinicians in osteoporosis should be improved necessarily and emergently.
