Ophthalmic Syndrome Differentiation System and Digital Chinese Medicine

In traditional Chinese medicine(TCM),ophthalmic syndrome differentiation is an ophthalmology-specific method for identifying syndromes based on the“Five Orbiculi”theory.It was devised by Professor Qing-Hua PENG through an unprecedented combination of syndrome element differentiation and ophthalmic clinical practices,based on the Clinical Terminology of Chinese Medical Diagnosis and Treatment-Syndromes of the National Standards of the People's Republic of China.This approach integrates an ophthalmic syndrome differentiation system with digital Chinese medicine(DCM),and proposes the extraction of syndrome elements of ophthalmic diseases from research on DCM.These elements are then quantified and organized to form a model of digital diagnosis and treatment specific to ophthalmology,which should help to achieve synergistic development of the ophthalmic syndrome differentiation system and DCM.

Clinical distribution and molecular profiling on postoperative colorectal cancer patients with different traditional Chinese medicine syndromes

Background:Traditional Chinese medicine(TCM)syndrome,also named syndrome,are comprehensive and integral analyses of clinical information which helps to guide different individualized treatment prescriptions.Methods:Thirty healthy controls and 80 colorectal cancer(CRC)patients(including 33 Spleen Qi Deficiency syndrome,23 Dampness Heat syndrome,17 Blood Stasis syndrome and 7 other syndrome)were enrolled into this study.Human mRNAs were extracted from peripheral blood mononuclear cells.The gene expression for CRC patients with different TCM syndrome was determined by microarray and qRT-PCR.Results:Spleen Qi Deficiency,Dampness Heat and Blood Stasis were the most common syndromes in CRC patients.There is a significant difference was found in mRNA expression levels(especially for PIK3CA,STAT3,SOX9 and KDM5C)among Spleen Qi Deficiency,Dampness Heat and Blood Stasis syndrome groups.The higher mRNA levels of JNK1,TP53,MLH1,MSH6,PMS2,SOCS3,TCF7L2,FAM123B,PSAP,FBXW7,SALL4 and the lower expression of inflammatory cytokine IL-6 were found in Spleen Qi Deficiency group but not other syndrome types.The higher mRNA levels of KRAS,MUC16,EGFR,GRASP65,PIK3CA,MAPK7,CD24,STAT3,SLC11A1,Bcl-2,TXNDC17 and some inflammatory cytokines(IL-6,IL-23,TNF-a,CXCR4)were found in Dampness Heat group but not other syndrome types.Blood Stasis syndrome showed higher expression of SOX9,MLH1,MSH6,KDM5C,PCDH11X,PSAP and SALL4,and lower mRNA levels of PIK3CA,CD24,STAT3,CXCR4,TXNDC17 and TP53.The CRC patients with Dampness Heat syndrome might have a poor prognosis than other syndrome types.Conclusion:The identification of syndrome conditions had different impacts on CRC prognosis,and which might be related with different mRNA expression levels.Some oncogenes and pro-inflammatory cytokines were highly expressed in Dampness Heat group but not other syndrome types,suggesting that the CRC patients with Dampness Heat syndrome might have a poor prognosis.Our results prelimitarily uncovered the molecular basis of syndrome differences in CRC prognosis,a better understanding for TCM treatment of CRC.

Selecting An Appropriate Interestingness Measure to Evaluate the Correlation between Chinese Medicine Syndrome Elements and Symptoms

To select the best interestingness measure appropriate for evaluating the correlation between Chinese medicine （CM） syndrome elements and symptoms, 60 objective interestingness measures were selected from different subjects. Firstly, a hypothesis for a good measure was proposed. Based on the hypothesis, an experiment was designed to evaluate the measures. The experiment was based on the clinical record database of past dynasties including 51 186 clinical cases. The selected data set in this study had 44 600 records. Cold and heat were selected as the experimental CM syndrome elements. Three indicators calculated according to the distances between two CM syndrome elements were obtained in the experiment and combined into one indicator. The Z score, φ-coefficient, and Kappa were selected from 60 measures after the experiment. The Z score and φ-coefficient were selected according to subjective interestingness. Finally, the φ-coefficient was selected as the best measure for its low The method introduced in this paper may be used in other similar territories.

Effect of Chinese Medicine Treatment Based on Pattern Identification on Cellular Immunophenotype of Myelodysplastic Syndrome

Objective： To observe the influence of treatment based on Chinese medicine pattem identification on cellular immunophenotype of the myelodysplastic syndrome （MDS）. Methods： Sixty patients with MDS were randomly and equally assigned to the treatment group and the control group using a randomized digital table. Thirty patients in each group included 3 risk levels （low, moderate and high risks） with each level 10 patients according to the international prognostic scoring system. The control group was given conventional therapy which was also used in the treatment group. While the treatment group was given Zuogui Pill （左归丸） and Yougui Pill （右归丸） for low risk patients; Qingwen Baidu Decoction （清瘟败毒饮） and Bazhen Decoction （八珍汤） for moderate risk patients; Gexia Zhuyu Decoction （膈下逐瘀汤） and Qinghao Biejia Decoction （青蒿鳖甲汤） combined with Shiquan Dabu Decoction （十全大补汤 ） for high risk patients. After the treatment, the differences of overatl response rate and immunophenotype （CD13, CD14, CD15, CD33 and CD34） of each group were analyzed. Results： The overall response rate of the treatment group was significantly higher than the control group in low risk and moderate risk patients （P=0.029）, there was no statistical differences of overall response rate between the treatment group and the control group in high risk patients （P=0.089）. The expressions of CD13, CD14, CD33 and CD34 in all three risk levels of the treatment group were obviously decreased after the treatment, while CD15 in all three risk levels of the treatment group was obviously increased after the treatment （P〈0.05 or P〈0.01）. Meanwhile, the difference values of CD13 and CD33 in low risk level of the treatment group, CD33 and CD34 in moderate risk level of the treatment group as well as CD34 and CD15 in high risk level of the treatment group, were all greater than the control groups and they were statistically significant （P〈0.05 or P〈0.01）. Conclusions： It shows a better therapeutic effect if the MDS patients treated with Chinese medicine pattern identification in addition to conventional therapy. Since the treatment may inhibit the malignant clones and improve the dysmaturity of granulocyte differentiation, it is a feasible option in clinical practice.

A data-driven method for syndrome type identification and classification in traditional Chinese medicine

The efficacy of traditional Chinese medicine （TCM） treatments for Western medicine （WM） diseases relies heavily on the proper classification of patients into TCM syndrome types. The authors developed a data-driven method for solving the classification problem, where syndrome types were identified and quantified based on statistical patterns detected in unlabeled symptom survey data. The new method is a generalization of latent class analysis （LCA）, which has been widely applied in WM research to solve a similar problem, i.e., to identify subtypes of a patient population in the absence of a gold standard. A well-known weakness of LCA is that it makes an unrealistically strong independence assumption. The authors relaxed the assumption by first detecting symptom co-occurrence patterns from survey data and used those statistical patterns instead of the symptoms as features for LCA. This new method consists of six steps： data collection, symptom co-occurrence pattern discovery, statistical pattern interpretation, syndrome identification, syndrome type identification and syndrome type classification. A software package called Lantern has been developed to support the application of the method. The method was illustrated using a data set on vascular mild cognitive impairment.

Potential of Renal Pathology on Refining Syndrome Typing of Chinese Medicine in IgA Nephropathy

Objective： To investigate the potential of renal pathological index as a differential diagnosis factor for Chinese medicine （CM） syndromes typing in IgA nephropathy （IgAN）. Methods： A total of 1,016 patients with IgAN was recruited from November 2001 to November 2004. All the signs and symptoms including picture of the tongue and pulse tracings were collected. All patients were typed according to the CM syndrome typing scheme for chronic primary glomerulopathy. The severity of glomerulus and tubulointerstitial lesions （mild, moderate- severe） were evaluated using lee＇s grading system and the Katafuchi score system. Results： The syndrome types transform in turn by deficiency of both the Spleen （Pi） and Lung （Fei） qi, deficiency of both qi and yin, deficiency of Liver （Gan） and Kidney （Shen） yin and deficiency of Spleen-Kidney （Shen） yang, with the aggravation of pathogenetic condition and that the manifestation of deficiency of qi clinically showed proliferative lesion of glomerular mesangium, while the glomerular sclerosis pathologically showed the manifestation of yin deficiency. Conclusion： Renal pathological findings may be a candidate of objective factors to refine CM syndrome typing process.

Biologic basis of TCM syndromes and the standardization of syndrome classification

Traditional Chinese medicine(TCM)syndrome is an integral and essential component of TCM theory,and goes beyond philosophic concepts.This article reviews the concept of TCM syndromes and summarizes research findings on the biologic foundation of syndromes.In addition,insight is provided into the promotion of standardization of syndrome classification by enforcing uniformity of TCM terminology,applying standardized diagnostic criteria and operating procedures to minimize subjective effects.Also incorporating interdisciplinary approaches such as data mining and structure modeling,as well as integrating findings on biomarker research are discussed.Consideration is made of the fundamental TCM aspects of syndrome elements,symptoms,phenotypic features,as well as diseases,to form an integral process in the diagnostic path.We believe that better understanding of the biologic basis of the TCM syndrome and standardization of syndrome classification will improve diagnosis,which in turn will enhance therapeutic efficacy and disease prognosis.

Acupuncture treatment of empty nose syndrome:A case report

Background:Empty nose syndrome(ENS)is an iatrogenic disorder that most commonly presents with paradoxical nasal obstruction.Diagnosis of ENS is based mainly on symptomatology and surgical history.Symptomatic or surgical treatment is typically offered to patients.Case presentation:A 17-year-old Chinese male presented with ENS following inferior turbinate resection.His main symptoms were dizziness and nasal congestion.He was diagnosed with a traditional Chinese medicine syndrome pattern of liver yang ascending.Acupuncture treatment involved needling ST 36(Zusanli)GB 20(Fengchi),PC 6(Neiguan),LI 4(Hegu),LR 3(Taichong),LR 2(Xingjian),GB 43(Xiaxi),DU 20(Baihui),EX-HN3(Yintang),ST 2(Sibai),and LI 20(Yingxiang).Near complete resolution of dizziness and nasal congestion were achieved after 2 treatments.Conclusion:Acupuncture may be used to resolve symptoms of ENS.Acupoint selection and needle manipulation should be based on TCM pattern diagnosis.

Incorporating Pattern Identification of Chinese Medicine into Precision Medicine:An Integrative Model for Individualized Medicine

On 20 January, 2015, U.S. President Obama announced an ambitious plan called ＂Precision Medicine （PM） Initiative＂, aiming to deliver genetics- based medical treatments. PM has shown a promising prospect by tailoring disease treatments and preventions to individuals. However, a predominantly genetics-based method restricts its benefit and applicability in most chronic and complex diseases. Pattern identification （PI） is one of the representative characteristics of Chinese medicine implying the concept of holism and individualized treatment. It is another classification method taking environmental, psychosocial and other individual factors into account. Integrating PI with disease diagnosis of Western medicine will provide a strong complement to genetics-based PM, thus establish an integrative model for individualized medicine. PI provides new perspectives for PM, not only in clinical practice, but also in new drug development and clinical trial design. It is for sure that the integrative approach will ultimately lead to a safer, more convenient and effective patient-centered healthcare and most patients will benefit in the era of PM.

Traditional Chinese Medicine Pattern Classification and Herbal Medicine for COVID-19: A Comparative Study of Data from Different Sources

Background: Traditional Chinese medicine(TCM) plays a crucial role in the prevention and control of coronavirus disease 2019(COVID-19). Objective: The study aimed to reveal the distribution characteristics of COVID-19 TCM syndrome types and syndrome elements and the law of TCM treatment and medication. Methods: The TCM diagnosis and treatment protocol for COVID-19 and clinical research data were obtained through network retrieval, and Revman 5.3 and SPSS 23.0 were employed to analyze the composition of TCM syndromes and the situation of TCMs in meta and frequency. Results: The top three TCM syndromes of COVID-19 included damp-heat accumulation in the lung pattern, damp abundance due to spleen deficiency, and epidemic toxin invading the lung pattern, while the syndrome elements were dampness, heat, and toxin. Gypsum fibrosum, Pogostemonis herba, and Armeniacae semen were identified as the commonly used drugs. Different syndrome elements were identified at lung disease location: Forsythiae fructus, Glycyrrhizae radix, and Armeniacae semen can be used for “wind;” Glycyrrhizae radix, Armeniacae semen, and Scutellariae radix can be used for “Heat;” Armeniacae semen, Sheng Gypsum fibrosum, and Ephedrae herba can be used for “Toxin;” Ephedrae herba, Armeniacae semen, and Atractylodis rhizome can be used for “Damp;” Magnoliae officinalis Cortex, Ephedrae herba, and Zingiberis Rhizoma recens can be used for “cold;” and Armeniacae semen, Gypsum fibrosum, Ephedrae herba, and Lepidii/Descurainiae semen can be used for “epidemic.” Conclusion: The establishment of a treatment scheme based on the classification of disease syndrome elements should be considered for sudden infectious diseases, such as COVID-19. Pogostemonis herba, Armeniacae semen, Gypsum fibrosum, and Glycyrrhizae radix should be considered as effective drugs from TCM for the treatment of COVID-19.

Appraisal of the Quality and Contents of Clinical Practice Guidelines for Hypertension Management in Chinese Medicine: A Systematic Review

Objective： To evaluate the quality and consistency of recommendations in the clinical practice guidelines（CPGs） for hypertension in Chinese medicine（CM）. Methods： CM CPGs were identified from 5 electronic databases and hand searches through related handbooks published from January 1990 to December 2013. Three reviewers independently appraised the CPGs based on the Appraisal of Guidelines for Research and Evaluation（AGREE Ⅱ） instrument, and compared the CPGs＇ recommendations on CM syndrome pattern classification and treatment. Results： Five CM CPGs for hypertension were included. The quality score of the evidence-based（EB） guideline was higher than those of the consensus-based with no explicit consideration of evidence-based（CB-EB） and the consensus-based（CB） guidelines. Three out of five patterns in the CPGs were recommended by the EB guideline. Tianma Gouteng Formula（天麻钩藤复方） in the EB guideline was recommended mostly for hypertension patients with pattern of ascendant hyperactivity of Gan（Liver）-yang and pattern of yin deficiency with yang hyperactivity in the CPGs. Acupuncture and massage were recommended for Grade Ⅰ and Grade Ⅱ hypertension with severe symptoms weakening the quality of life in the EB guideline. For Grade Ⅰ and Grade Ⅱ hypertension, CM could be used alone, while for Grade Ⅲ hypertension, they should be used in combination with Western medicines. Conclusion： The quality of EB guideline was higher than those of CB and CB-EB CPGs in CM for hypertension and CM should be prescribed alone or combined with Western medicines based on the grade of hypertension.
