RESUMO
Objective:To analyze the distribution characteristics of traditional Chinese medicine (TCM) syndromes in patients with coronavirus disease 2019 (COVID-19) in plateau areas, and to provide theoretical basis for further clinical treatment of patients with COVID-19.Methods:From August 9 to August 24, 2022, patients with COVID-19 admitted to the Third People's Hospital of Tibet Autonomous Region (designated hospital for COVID-19) were included, and their baseline characteristics (age, gender, source), clinical classification and distribution of TCM syndrome types were collected and analyzed. Data analysis was performed using SPSS 26.0 statistical software.Results:A total of 161 COVID-19 patients were enrolled with ethnic distribution: 124 (77.02%) Tibetans, 35 (21.74%) Han, and 2 (1.24%) Hui, 68 males and 93 females. The male-to-female ratio was 0.73∶1. Aged 1 to 94 years, the average age was (39.06±23.64) years old, of which 4 patients were under 1 year old (excluded because the information was missing). A total of 157 patients were enrolled, and 124 patients (78.9%) were under 60 years old, including 120 cases of common type, 4 cases of severe type, 0 cases of critical type, 7 cases over 80 years old, 1 case over 90 years old, and 32 cases under 18 years old. The clinical manifestations of the patient are mainly cough, expectoration, fever, aversion to cold, dry throat, headache, fatigue, running nose, dry mouth, bitter mouth, etc. Most of the tongue is pale, red, and white greasy moss or thin white coating. In TCM, the most common syndrome was cold-dampness blocking lung syndrome (99 cases, 63.06%), followed by cold-dampness stagnant lung syndrome (22 cases, 14.01%), damp-heat accumulating lung syndrome (22 cases, 14.01%), and humidity stagnant lung syndrome (11 cases, 7.01%). Syndromes of epidemic (2 cases, 1.27%), epidemic toxins blocking the lung pattern (1 cases, 0.64%), toxins with dryness intense heat in both qi and ying phases pattern (0 cases) accounted for less than 2%, and the distribution of various syndrome types in COVID-19 patients was uneven ( χ2 = 0.48, P < 0.05). Conclusion:The most common TCM syndromes of COVID-19 patients in Lhasa are cold-dampness blocking lung syndrome, followed by cold-dampness stagnant lung syndrome, damp-heat accumulating lung syndrome, and humidity stagnant lung syndrome.
RESUMO
Objective:To observe the effect of serum of kidney Yang deficiency rats on the expression of β-catenin，osteoprotegerin(OPG) and nuclear transcription factor-κB receptor activator ligand (RANKL) in the co-culture system and regulatory of icariin on it， and to explore the possible mechanism of inducing osteoporosis.Method:The 16 male SD rats were randomly divided into blank group and model group， 8 rats in each group. 10 mL·kg-1 adenine was administrated to stomach to establish kidney yang deficiency model. Serum was separated and extracted after the model was established successfully. Isolation and culture of osteoblast（OB） and osteoclast（OC） in vitro， OB was observed and identified by alkaline phosphatase（ALP），alizarin red and Giemsa staining， OC was identified by tartrate resistant acid phosphatase（TRAP） staining， OB-OC co-culture system was established in transwell cell， icariin group（100 μmol·L-1）， blank group， icariin（100 μmol·L-1） + serum group， serum group and Dickkopf1（DKK-1） drug（100 μg·L-1） were set up in group ， 2 days after intervention of co-culture system， OC was counted， ALP and TRAP in supernatant were detected by microplate enzyme labeling， and the expression of OPG，β-catenin and RANKL in each group was detected by Western blot.Result:Compared with blank group， the ALP activity，β-catenin and OPG protein expression in serum group were significant reduction （P<0.05）， while the OC quantity， TRAP activity and RANKL protein expression were marked increase （P<0.05）. Compared with serum group， ALP activity of icariin group decreased significantly （P<0.01）， Compared with icariin group， ALP activity and OPG protein expression decreased （P<0.05）， trap activity and RANKL expression increased （P <0.05） in icariin + serum group.Conclusion:The serum of kidney Yang deficiency rats can induce the occurrence of osteoporosis， and the mechanism of action may be through inhibition of ALP activity， down regulating the expression of β-catenin and OPG protein， increasing the activity of TRAP and the expression of RANKL protein.
RESUMO
The whole concept and syndrome differentiation are the two major characteristics of traditional Chinese medicine (TCM).Metabonomics can reflect the characteristics of TCM syndromes and is an effective method to explore the relationship between the essence of TCM syndromes and the evolution of deficiency and excess of diseases.In this paper,the research progress of syndromes metabolism in TCM in recent years is summarized.
RESUMO
Objective To explore the Chinese medicine syndrome characteristics of mild cognitive impairment (MCI).Methods The papers of MCI syndrome research were reviewed and collected in China National Knowledge Infrastructure,Wan Fang Data and VIP Data from January of 1990 to December of 2014.Statistical analysis was made on the Chinese medicine syndrome types and syndrome factors.SPSS 17.0 software was adopted to make cluster analysis.Combined with experts' experience,related symptoms to the syndrome factors were carried out.Results Totally 32 papers were included.Mter terminology normalization,there were 24 syndrome types of MCI.Top 5 syndromes with high frequency were syndrome of orifices confused by phlegm,syndrome of deficiency of kidney essence,syndrome of deficiency of both Qi and blood,syndrome of internal exuberance of heat toxin and syndrome of blood stasis blocking brain.In syndrome factors of disease location type,kidney and brain covered the highest proportion,30.83％ and 30.00％.In syndrome factors of disease cause and character types,Qi deficiency covered the most,16.50％.According to results of cluster analysis,combined with experts' experience,15 syndrome factors were extracted,including 69 symptoms.Conclusion Chinese medicine syndrome types of MCI were mainly syndrome of orifices confused by phlegm and syndrome of deficiency of kidney essence.The disease locations were mainly kidney and brain.The disease character was Qi deficiency.
RESUMO
Objective To explore college students’ sleep and insomnia syndrome type of traditional Chinese medicine.Methods A questionnaire survey was conducted among 1 325 college students of independent colleges using the Pittsburgh sleep quality index and the standardization of TCM syndrome introduced by guiding principles of clinical research on treatment of insomnia with new drugs of traditional Chinese medicine (2002).The results underwent analysis.Results Of 1 325 college students in independent college,209 people had poor sleep quality,in which liver fire retarding type accounted for 129 people,hyperactivity of fire due to yin deficiency type accounted for 67 people,followed by the heart and spleen deficiency type two(3 people),phlegm heat disturbance type(4 people),Qi deficiency type (2 people),other type (4 people).Conclusions College students in sub-health state with insomnia showed two common types:liver depression transforming into fire,hyperactivity of fire due to yin deficiency type.We should give effective intervention based on dialectical theory of the Chinese medicine.
