ABSTRACT
Objective:To explore the prescription and medication law of Traditional Chinese Medicine (TCM) compounds in the treatment of vascular dementia (VD) based on patent database.Methods:TCM compounds with patents about VD were retrieved from Chinese patent announcement website of the State Intellectual Property Office and CNKI. The retrieval time was from the establishment to the databases to 31 st, March 2022. The frequency, clusteringand association analysis were carried out with the help of TCM inheritance auxiliary platform (V2.5). The medication law was analyzed. Results:154 TCM compound patents for the treatment of vascular dementia were screened, involving 227 kinds of Chinese materia medica. Among them, Acori Tatarinowii Rhizoma (44 times, 28.57%) was used more frequently, and the common medicinal pair was Salviea Miltiorrhizae Radix et Rhizoma- Acori Tatarinowii Rhizoma (17 times, 11.03%). The medicinal property was mainly warm, the taste was mainly sweet, and the meridian was mainly liver meridian. Those with high confidence based on association rules were " Corni Fructus -Acori Tatarinowii Rhizoma" (0.90), " Corni Fructus -Rehmannize Radix et Praeparata" (0.90). Based on the complex network, it was concluded that the core drugs were 14 groups such as " Rehmannize Radix et Praeparata- Cistanches Herba- Corni Fructus". The new prescriptions extracted by entropy cluster analysis included 7 groups such as " Rehmannize Radix et Praeparata, Cistanches Herba, Corni Fructus and Asparagi Radix". Conclusion:The treatment of VD by TCM compounds with national patents is mainly based on tonifying deficiency, promoting blood circulation and removing blood stasis, eliminating phlegm and dampness, expelling wind and dredging collaterals, opening orifices and resuscitation, which can provide reference for clinical practice and new drug research and development.
ABSTRACT
Objective:To investigate the distribution law of TCM syndrome types and the differences in influencing factors among different syndrome types in unstable angina pectoris (UA), so as to provide an objective basis for TCM syndrome differentiation and treatment of UA.Methods:A retrospective study chose 1 684 inpatients in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Henan University of Chinese Medicine from August 2015 to April 2019. Epidata 3.0 software was used to input general information of patients [gender, age, length of hospital stay, BMI, systolic blood pressure (SBP), diastolic blood pressure (DBP)], laboratory indicators[TC, TG, HDL-C, LDL-C, fibrinogen (FIB), thrombin time (TT), D-dimer (D-dimer), HbA1c], TCM syndrome types (qi and yin deficiency syndrome, phlegm turbidity and obstruction syndrome, qi deficiency and blood stasis syndrome, heart blood stasis syndrome, qi stagnation and blood stasis syndrome, heart and kidney yang deficiency syndrome) and other information. A database was established to analyze the distribution of TCM syndrome types and the relationship with the general information of patients, blood lipids, blood sugar and coagulation indexes. Logistic regression was used to analyze the influencing factors of different syndrome types.Results:The distribution of syndrome types in 1 684 UA patients was as follows: qi and yin deficiency syndrome (44.7%), phlegm turbidity and obstruction syndrome (35.3%), qi deficiency and blood stasis syndrome (7.4%), heart blood stasis syndrome (5.3%), qi stagnation and blood stasis syndrome (4.6%), heart and kidney yang deficiency syndrome (2.6%); more men than women ( P<0.05); there were significant differences in the distribution of gender, age, BMI, TC, and HDL-C among the 6 syndrome types ( P<0.05); the age of patients with phlegm turbidity and obstruction syndrome was younger than that of qi and yin deficiency syndrome and heart blood stasis syndrome ( P<0.05); the age of patients with qi stagnation and blood stasis syndrome was younger than that of qi and yin deficiency syndrome, heart blood stasis syndrome, and heart kidney yang deficiency syndrome ( P<0.05); BMI of patients with phlegm turbidity and obstruction syndrome was higher than that of qi and yin deficiency syndrome and qi stagnation and blood stasis syndrome ( P<0.05); the level of TC in patients with phlegm turbidity and obstruction syndrome was lower than that of qi and yin deficiency syndrome and qi deficiency and blood stasis syndrome ( P<0.05); the level of HDL in patients with qi and yin deficiency syndrome was lower than that in qi deficiency and blood stasis syndrome and qi stagnation and blood stasis syndrome. Binary Logistic regression analysis found that TC [ OR(95% CI)=0.761(0.592, 0.978)] and HDL-C [ OR(95% CI)=2.131(1.145, 3.966)] were independent influencing factors for predicting qi deficiency and blood stasis syndrome ( P<0.05); age[ OR(95% CI)=1.017 (1.008, 1.026)], length of hospital stay [ OR(95% CI)=1.019 (1.001, 1.038)], DBP [ OR(95% CI)=0.984(0.975, 0.993)] and HDL-C [ OR(95% CI)=0.984(0.975, 0.993)] were independent influencing factors for predicting qi and yin deficiency syndrome ( P<0.05); age [ OR(95% CI)=0.965 (0.946, 0.985)], and HDL-C [ OR(95% CI)=2.329(1.206, 4.500)] were independent influencing factors for predicting qi stagnation and blood stasis syndrome ( P<0.05); age [ OR(95% CI)=0.982 (0.973, 0.991)], length of hospital stay [ OR(95% CI)= 0.978 (0.958, 0.997)], BMI [ OR(95% CI)=1.048 (1.015, 1.082)], DBP [ OR(95% CI)=1.014 (1.004, 1.024)] and HDL-C [ OR(95% CI)=0.505 (0.351, 0.726)] were independent influencing factors for predicting phlegm turbidity and obstruction syndrome ( P<0.05); age [ OR(95% CI)=1.031(1.003, 1.060)] and DBP [ OR(95% CI)=1.028(1.001, 1.056)] were independent influencing factors for predicting heart kidney yang deficiency syndrome ( P<0.05). Conclusion:The distribution of TCM syndrome types in UA shows a certain regularity, among which qi and yin deficiency syndrome and phlegm turbidity and obstruction syndrome are more common. Gender, age, BMI, TC, HDL-C are different among TCM syndrome types, which can provide some reference for UA TCM syndrome differentiation and treatment.

ABSTRACT
As the guiding theory for the diagnosis and treatment of encephalopathy in traditional Chinese medicine （TCM）， The marrow sea theory has important theoretical connotation and clinical value. This paper summarized the clinical research literature on the differentiation and treatment of common encephalopathy based on the marrow sea theory published in recent years， analyzed the treatment method and effects from eight aspects in terms of stroke， dizziness， insomnia， headache， constraint syndrome， dementia， tremor syndrome， and atrophy syndrome， and discussed the possible mechanism based on the relevant basic research. It is believed that marrow sea depletion is the common pathogenesis of encephalopathy in TCM. Guided by the method of supplementing essence and boosting marrow， the corresponding formulas and medicinals are recommended in accordance with differentiated syndromes， which can effectively improve the symptoms of the disease， delay the progression， increase the daily life ability of the patients， and improve the quality of life. Based on the marrow sea theory， the method of supplementing essence and boosting marrow， rectifying healthy qi and dispelling pathogen can be used to highlight the advantages of TCM and provide ideas for the diagnosis and treatment of encephalopathy in TCM.
ABSTRACT
ObjectiveTo discuss the thought of treatment of orifices in the Chinese herbal classics in the past dynasties based on the correspondence between drugs and symptoms to guide the clinical treatment based on syndrome differentiation. MethodAll the literature data of Chinese herbal classics were retrieved from the database of the Chinese Medical Dictionary， involving 76 works of Chinese herbal classics and covering representative works from the Han dynasty to the Ming and Qing dynasties. The information on Chines herbal drugs for the treatment of orifices was collected and sorted out. According to Chinese Materia Medica （11th Edition） and Pharmacopoeia of the People's Republic of China （2020 Edition）， the nature， flavor， and meridian tropism of the selected Chinese herbal drugs were statistically analyzed. The pathogenesis elements in the treatment of orifices were classified and counted， and the contents of syndrome differentiation and treatment in various Chinese herbal classics were extracted. ResultIn 76 Chinese herbal classics in the past dynasties， 93 Chinese herbal drugs for the treatment of orifices were selected. The nature of drugs was mainly warm， followed by cold and mild. The flavor was mainly pungent， followed by bitter and sweet. In terms of meridian tropism， drugs mainly acted on the lung meridian， followed by stomach， heart， liver， spleen， and kidney meridians. The pathogenesis elements of orifices could be divided into six categories， i.e.， wind invasion， turbid obstruction and Qi stagnation， water and dampness stagnation， blood stasis and collaterals blockage， heat and toxin damage， deficiency of vital Qi and cold coagulation. ConclusionOrifices are mainly treated with drugs effective in dispelling wind and pathogenic factors， resolving turbidity and removing stagnation， inducing diuresis and eliminating dampness， promoting blood circulation and dredging collaterals， clearing heat and purging fire， tonifying deficiency and dispelling cold， which are used in combination. Eliminating pathogenic factors and dredging， tonifying deficiency and purging excess are the main characteristics of treatment of orifices based on syndrome differentiation， which is in line with the physiological dysfunction state of orifices in losing the function， evil Qi blockage and healthy Qi deficiency.
ABSTRACT
ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods， i.e.， carrageenan （Ca）， Ca combined with dried yeast （Ca+Yeast）， and Ca combined with lipopolysaccharide （Ca+LPS）. MethodForty SPF male SD rats were randomly divided into normal group， Ca group， Ca+Yeast group， and Ca+LPS group， with 10 rats in each group. The Ca group， Ca+Yeast group， and Ca+LPS group received an intraperitoneal injection of Ca （10 mg·kg-1） on the first day. The Ca+LPS group received an intraperitoneal injection of LPS （50 μg·kg-1） on the second day， and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension （2 mg·kg-1） on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling， the macroscopic evaluation indexes， including tongue manifestation， pulse， and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay （ELISA） was used to detect the interleukin-6 （IL-6） level in the rat plasma. The myocardial tissue， brain tissue， and lung tissue of each group of rats were observed by hematoxylin-eosin （HE） staining. ResultCompared with the normal group， all three model groups showed varying degrees of black tail （P<0.05， P<0.01）， reduced blood flow perfusion at the tail end （P<0.05， P<0.01）， decreased R， G， and B values of tongue manifestation （P<0.05， P<0.01）， and increased maximum platelet aggregation rate （P<0.05， P<0.01）. The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group （P<0.05， P<0.01）. In addition， the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling （P<0.01）， and the low-， medium-， and high-shear whole blood viscosity and plasma viscosity increased （P<0.05， P<0.01） as compared with those in the normal group. Additionally， the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated （P<0.05）. Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes， with small foci of myocardial fiber dissolution， inflammatory cell infiltration， and fibroblast proliferation observed. In the hippocampal area， the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium， lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast. The systematic evaluation system of the model， which includes traditional Chinese medicine four diagnostic information， western medicine microscopic indicators， and tissue pathological morphology， is worthy of consideration and reference by researchers.
ABSTRACT
This paper summarized Professor ZHANG Yunling's experience in the treatment of amyotrophic lateral sclerosis （ALS） from emphasis on both spleen and kidney. It is considered that the characteristic of ALS manifested as overlap of atrophy-flaccidity disease and convulsive disease， and the core pathogenesis are the deficiency of spleen and kidney and the inner pathogenic qi. ZHANG advocated that ALS should be treated from tonifying both the spleen and kidney， as strong spleen and kidney led the latent pathogen at peace. Usually applied Huangqi （Astragalus mongholicus）， Baizhu （Atractylodes macrocephala） combined with Taizishen （Pseudostellaria heterophylla）， fried Yiyiren （Coix lacryma-jobi）， Doukou （Myristica fragrans） and Sharen （Wurfbainia villosa） to tonify the middle and replenish qi， ascend lucidity and descend turbidity to invigorate the spleen； Roucongrong （Cistanche deserticola）， Tusizi （Cuscuta chinensis） combined with Shanyao （Dioscorea oppositifolia）， Shanzhuyu （Cornus officinalis） and prepared Dihuang （Rehmannia glutinosa） are used to support the fire and nourish the water， so as to replenish the spleen. The empirical formula regarded invigorateing the spleen and replenishing the kidney as the core therapeutic principle throughout the treatment of the whole process， which aimed at extinguishing inner wind and pacifying latent pathogen when treating the root.

ABSTRACT
Gastric cancer （GC） is one of the common malignant tumors， and the incidence and mortality of GC in China rank first in the world. At present， the pathogenesis of GC has not been fully clarified. Although surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy have achieved good results in the treatment of GC， there are still many complications， decreased sensitivity， and severe side effects. Banxia Xiexintang， derived from Treatise on Cold Damage and Miscellaneous Diseases（《伤寒杂病论》）， has been clinically used for more than 2000 years with the effects of combining cold and warm drugs， dissipating mass， and relieving stuffiness， and is a classic prescription for treating digestive tract diseases in later generations. Through clinical observation and experimental research， it is found that Banxia Xiexintang and its single drugs have good effect in preventing and treating GC. Chinese medicine has multi-component and multi-target characteristics and can treat GC through various mechanisms. Therefore， it is necessary to carry out systematic and in-depth research from the aspects of molecular biology and network pharmacology， and comprehensively reveal the mechanism of Banxia Xiexintang in preventing and treating GC. At present， the mechanism of Banxia Xiexintang in treating GC mainly focuses on inducing apoptosis of GC cells， inhibiting proliferation， migration， and invasion of GC cells， protecting peritoneal mesothelial cells， inhibiting peritoneal metastasis of GC cells， regulating GC microenvironment， and inhibiting the malignant transformation of bone marrow mesenchymal stem cells （BMSCs）. This research group is committed to the prevention and treatment of GC with Banxia Xiexintang， aiming to comprehensively reveal the mechanism of action and the pharmacodynamic material basis of Banxia Xiexintang in the prevention and treatment of GC， and provide an important scientific basis for further clinical application of Banxia Xiexintang. After searching CNKI， PubMed， Wanfang Data， VIP， and other databases， this paper summarized Banxia Xiexintang in the treatment of GC from the aspects of prescription basis， material basis， network pharmacology， clinical and experimental studies， etc.， so as to provide references for further research on pharmacological effect of Banxia Xiexintang and its application in the clinical treatment of GC.
ABSTRACT
ObjectiveTo observe the effect of Banxia Xiexintang （BXT）-containing intestinal absorption solution on the apoptosis of polymorphonuclear myeloid-derived suppressor cells （PMN-MDSCs） in gastric cancer microenvironment. MethodBXT-containing intestinal absorption solution was prepared， and gastric cancer cells and PMN-MDSCs were non-contact co-cultured in Transwell chamber to establish gastric cancer microenvironment. Cell counting kit-8 （CCK-8） assay was used to screen the optimal intervention concentration and time of 0-100% BXT-containing intestinal absorption solution prepared by 0.63 g·mL-1 reconstitution solution. Cells were classified into blank group， model group， oxaliplatin group （10 mg·L-1）， and BXT （26%， 18%， 10% BXT-containing intestinal absorption solution） group， and the apoptosis of PMN-MDSCs was detected by flow cytometry. The expression of apoptosis-related B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and cysteine-aspartic acid protease-3 （Caspase-3） in PMN-MDSCs was detected by Western blot. ResultAfter treatment for 24 h and 48 h， the PMN-MDSCs-inhibiting rate was increased by 5%， 50%， 75%， and 100% BXT-containing intestinal absorption solution compared with that in the blank group （P<0.05， P<0.01）. At 72 h， the PMN-MDSCs-inhibiting rate by 50% BXT-containing intestinal absorption solution was lower than that at 48 h （P<0.01）， and the PMN-MDSCs-inhibiting rate by 5%， 75%， and 100% BXT-containing intestinal absorption solution showed no significant difference from that at 48 h. Moreover， the half-maximal inhibitory concentration （IC50） at 48 h was 18.40%. Thus， 18% BXT-containing intestinal absorption solution and 48 h were the optimal intervention concentration and time. The survival rate of PMN-MDSCs in model group was higher than that in the blank group （P<0.05）， and the apoptosis rate was lower than that in the blank group （P<0.05）. Compared with model group， BXT containing intestinal absorption solution lowered the survival rate and raised apoptosis rate of PMN-MDSCs （P<0.05）， particularly the 26% BXT-containing intestinal absorption solution （P<0.05）. The expression of Bax and Caspase-3 in PMN-MDSCs was lower in the model group than in the blank group （P<0.05）， and the expression of Bcl-2 was higher in the model group than in the blank group （P<0.05）. The expression of Caspase-3 in PMN-MDSCs increased （P<0.05） and the expression of Bcl-2 decreased （P<0.05） in oxaliplatin group and BXT group compared with those in the model group. The expression of Bax rose in oxaliplatin group and BXT group （10% BXT-containing intestinal absorption solution） （P<0.05）. ConclusionBXT can induce the apoptosis of PMN-MDSCs by regulating the expression of apoptosis-related proteins Bax， Caspase-3， and Bcl-2 in gastric cancer microenvironment.
ABSTRACT
ObjectiveTo observe the effect of Banxia Xiexintang containing intestinal absorption solution （BXCIAS） on migration and invasion of polymorphonuclear myeloid-derived suppressor cells （PMN-MDSCs） in gastric cancer microenvironment. MethodThe complex solution （containing 0.63 g·mL-1 crude drug） was prepared. Gastric cancer cells were subjected to non-contact co-culture with PMN-MDSCs in Transwell chamber to create gastric cancer microenvironment. Cell counting kit-8 （CCK-8） assay was used to screen the optimal intervention concentration and time of BXCIAS on PMN-MDSCs for subsequent experiment. The blank group， model group， FAK inhibitor group， and BXCIAS groups （26%， 18%， and 10%） were designed. Scratch assay and Transwell assay were employed to detect the migration and invasion ability of PMN-MDSCs， and enzyme-linked immunosorbent assay （ELISA） to measure the expression of vascular endothelial cell growth factor （VEGF） and matrix metalloproteinase-9 （MMP-9） in tumor microenvironment. The expression levels of PMN-MDSCs pathway-related proteins FAK， phosphorylated （p）-FAK， protein tyrosine kinase （Src）， and p-Src were detected by Western blot. ResultThe inhibition rates of PMN-MDSCs by 5%， 50%， 75%， and 100% BXCIAS at 48 h were higher than those at 24 h （P<0.05， P<0.01）. The inhibition rate of PMN-MDSCs by 50% BXCIAS at 72 h was lower than that at 48 h （P<0.01）， and the inhibition rates by 5% and 100% BXCIAS at 72 h were higher than those at 48 h （P<0.05， P<0.01）. There was no significant difference in the inhibition rate by other concentration levels at 48 h. The half-maximal inhibitory concentration （IC50） at 48 h was 18.09%， indicating that 18% BXCIAS and 48 h were the optimal concentration and time， respectively. The migration distance of PMN-MDSCs was large （P<0.01）， and the number of migrating and invading cells increased （P<0.01） in the mode group compared with those in the blank group. Compared with model group， FAK inhibitor and BXCIAS at different concentration decreased the migration distance of PMN-MDSCs （P<0.01）， and the number of migrating and invading cells （P<0.01）， especially the 26% BXCIAS （P<0.01）. The expression of PMN-MDSCs pathway-related proteins FAK， p-FAK， Src and p-Src （P<0.01） and the expression of VEGF and MMP-9 （P<0.01） were higher in the model group than in the blank group. Compared with model group， FAK inhibitor and BXCIAS （26%， 18%， 10%） decreased the expression of FAK， p-FAK， and Src （P<0.01）， and FAK inhibitor and 18% BXCIAS reduced the expression of p-Src （P<0.01）， and the expression of VEGF and MMP-9 （P<0.01）. ConclusionBXCIAS can inhibit the migration and invasion of PMN-MDSCs by down-regulating the expression of FAK， p-FAK， Src， and p-Src proteins in the FAK signaling pathway of PMN-MDSCs in gastric cancer microenvironment.
ABSTRACT
Objective:To investigate the expression of adenosine 5'-monophosphate-activated protein kinase (AMPK) phosphorylation in corneal epithelial cells and the effects of fungus on AMPK phosphorylation and interleukin-6 (IL-6) production in corneal epithelial cells.Methods:The human immortalized corneal epithelial cell line was selected.The safe concentration range of AMPK agonist 5-aminoimidazole-4-carboxamide 1-β-D-ribofuranoside (AICAR) (100, 300, 500, 1 000 μmol/L) and inhibitor Compound C (10.0, 12.5, 15.0, 17.5, 20.0 μmol/L) on corneal epithelial cells was screened by multi-function real-time unlabeled cell analyzer.Corneal epithelial cells without any treatment were used as the normal control group, and those co-cultured with spores were used as the spore control group.Corneal epithelial cells co-cultured with spores were treated with AICAR and Compound C for 4 hours in the AICAR group and Compound C group, respectively.The expression of phosphorylated AMPK (p-AMPK) and AMPK in corneal epithelial cells was detected by Western blot, and the concentration of IL-6 in the culture supernatant was determined by enzyme-linked immunosorbent assay (ELISA).Results:After treatment with different concentrations of AICAR for different periods, there was no statistical significance in the cell index of corneal epithelial cells (all at P>0.05). The cell index of corneal epithelial cells was increased with 10.0 μmol/L and 12.5 μmol/L Compound C treatment compared with that of the normal control group.The expression levels of p-AMPK were 0.67±0.15, 2.57±0.12, 3.67±0.58 and 1.50±0.50, respectively, in the normal control group, spore control group, AICAR group and Compound C group, showing a statistically significant difference among them ( F=32.820, P<0.001). The expression level of p-AMPK was significantly higher in the spore control group compared with the normal control group ( P<0.001). The expression level of p-AMPK in the AICAR group was higher than that in the spore control group, and the expression level of p-AMPK in the Compound C group was lower than that in the spore control group, and the differences were statistically significant (both at P=0.010). There was no significant difference in the relative expression level of AMPK among the four groups ( F=0.120, P=0.950). The expression levels of IL-6 concentration in the normal control group, spore control group, AICAR group and Compound C group were (107.81±17.15), (156.32±9.94), (167.96±14.16) and (127.42±19.75)pg/ml, respectively, showing a statistically significant difference among them ( F=15.210, P<0.001). The IL-6 concentration of the spore control group was higher than that of the normal control group, and the difference was statistically significant ( P<0.001). The IL-6 concentration of the AICAR group was higher than that of the spore control group, but the difference was not statistically significant ( P=0.260). The IL-6 concentration of the Compound C group was lower than that of the spore control group, and the difference was statistically significant ( P=0.010). Conclusions:In corneal epithelial cells, AMPK phosphorylation is found, which is enhanced after fungal spores stimulation, and the secretion of IL-6 increases.
ABSTRACT
Objectives:To explore the value of heparin-binding protein (HBP) in the diagnosis and prognosis of patients with respiratory viral infections.Methods:The patients who were admitted to Emergency Department of Nanjing Hospital Affiliated to Nanjing Medical University from November 2018 to November 2020 were selected as the viral infection group, and the non-infected patients admitted in the same period as the non-viral infection group. Data of all patients’ general clinical information, peripheral white blood cell count (WBC), neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), and HBP in 24 h were collected. The differences in various indicators were compared between the two groups of patients, the receiver operating characteristic (ROC) curves were drawn, and the diagnostic value of each indicator for patients with respiratory virus infection were evaluated. The prognostic indicators such as sequential organ failure assessment (SOFA) score, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score within 24 h were recorded, and duration of ICU stay, antiviral treatment, ventilator and vasoactive agents to total length of hospital stay of patients in the viral infection group were calculated. The Spearman correlation analysis of HBP and the above indicators was performed to determine the prognostic value of HBP in patients with respiratory virus infections.Results:A total of 106 patients were included in the viral infection group, and 107 in the non-viral infection group. There were no significant differences in sex, age, and body mass index (BMI) between the two groups of patients (P>0.05). Compared with the non-viral infection group, the serum CRP and HBP of the viral infection group were significantly higher (P<0.05), while the WBC and NLR levels were significantly lower (P<0.05). There was no statistical difference in PCT between the two groups (P>0.05). HBP had the best diagnosis efficiency for respiratory viral infections, the areas under the ROC was 0.895, the optimal cut-off point was 13.625 μg/L, the sensitivity was 92.50% and the specificity was 76.60%. Correlation analysis showed that serum HBP levels within 24 h in the viral infection group were positively correlated with SOFA score and APACHEⅡ score in 24 h after admission (r = 0.756, P<0.05; r = 0.747, P<0.05). In the viral infection group, duration of ICU stay, antiviral treatment, and ventilator and vasoactive agents to total length of hospital stay were also positively correlated with serum HBP level (r = 0.873, 0.748, 0.830, and 0.794, P<0.05).Conclusions:HBP can be used as a favorable diagnostic indicator for patients with respiratory virus infections and has a good evaluation value for the prognosis.
ABSTRACT
Malaysia is a multi-ethnic and multi-cultural constitutional monarchy and federal system located in Southeast Asia. The top three diseases that cause deaths are ischemic heart disease, lower respiratory tract infections and stroke. Lower respiratory tract infections, colorectal cancer and Alzheimer’s disease have been the fastest growing diseases in recent years. The health insurance system complements public and private health care system. Traditional medicine in Malaysia includes Malaysian Medicine, Traditional Chinese Medicine (TCM), Indian Medicine, Islamic Medicine and homeopathy. Although TCM, such as acupuncture, has not been covered by health insurance, it is widely used under the impetus of the local Chinese people. At present, in Malaysia, the TCM public acceptance and education need promotion, and scientific researches need to be improved. It is hoped that in the future, the development of TCM in Malaysia will be better developed and disseminated by promoting TCM relevant legislation, increasing public awareness, focusing on education and training, and carrying out international scientific research cooperation.

ABSTRACT
The medical insurance is provided by the Unified Health System (SUS) covering most of Brazilians and alsocombined with private insurance, and every Brazilan could get access to basic health services. The major diseaseas leading to death in Brazil are ischemic heart disease, stroke and lower respiratory infection. The incidence of AD, chronic kidney disease and diabetes are increasing in recent years. Traditional Chinese Medicine (TCM), which was represented by acupuncture, was introduced to Brazil in the early 19th. At present, acupuncture has been widely accepted and used, which was included in SUS. A number of universities have acupuncture courses. However, the specialities and advantages of TCM needs to be strengthened, the local practioners lack the understanding of TCM theory, the appropriate use of herbal medicine, and there lacks TCM education standards, all these limit the development of TCM. Thus, in order to promote the development and dissemination of TCM in Brazil, it is suggested to give full play of the characteristics of TCM in preventing disease, increase the research and development input of herbal medicine, standardize the education stystem of TCM, etc.
ABSTRACT
Serbia is a parliamentary republic country in Southeast Europe. It implements a health security system with social insurance as the mainstay and social assistance as a supplement. Ischemic heart disease, stroke and Alzheimer’s disease are the major causes of death, and the mortality rates of cardiomyopathy and chronic kidney disease are increasing. Serbia has relevant legislation on traditional medicine. Acupuncture, as the main form of Traditional Chinese Medicine (TCM), has been introduced to Serbia in an early stage. Acupuncture was recognized as a legal medical method in 2005, and then the corresponding educational institutions of TCM were established soon. However, the limitation of acupuncture treatment application, difficulty in access to Chinese medicine, and undeveloped of TCM education system, all of them restrict the development of TCM in Serbia. It is recommended to improve the development and dissemination of Chinese medicine in Serbia, like to increase the promotion of acupuncture, pay attention to the Chinese medicine for preventive health care, and strengthen TCM education.
ABSTRACT
The Algerian medical health system provides free medical care. The incidence of non-communicable diseases, such as ischemic heart disease, stroke and Alzheimer’s disease, are high. Acupuncture has become a popular treatment recognized by the public with certain influence. However, some problems restrict the development of Traditional Chinese Medicine (TCM) in Algeria, like insufficient training of TCM talents; lack of TCM related knowledge, and medical insurance policy uncoving TCM. Based on the status quo of TCM, we suggested promotion and dissemination of TCM development in Algeria, including breaking through education limitation to expand the talent team, carrying out targeted publicity to expand the influence of TCM, promoting the inclusion of TCM in medical insurance and government legislative protection. Only in these ways, could we increase and expand the strength and scope of TCM influence, and promote the development of TCM in Algeria.
ABSTRACT
Egypt’s medical insurance is mainly covered by government and commercial insurance. The low coverage of commercial insurance and the quality of medical services needs more improvement in Egypt. Recently, the incidence rate of diabetes, chronic kidney disease, hypertensive heart disease, COPD and liver cancer is rising. Traditional Egyptian medicine is similar to Traditional Chinese Medicine (TCM), and its modern traditional medicine is mainly Arabian medicine. Acupuncture, as the main form of TCM, was introduced into Egypt in the 1970s, but it has not been covered by the medical insurance system. The development of TCM in Egypt needs improvement. It is suggested that further explorated fields should be focused on the acupuncture therapy, TCM education and TCM treatment of keeping health in Egypt.
ABSTRACT
Iraq is a multi-ethnic, multi-religious federal country located in southwest Asia and northeast of the Arabian Peninsula. Medical insurance is based on the primary health care model, supplemented by private medical care. Traditional medicine in Iraq is dominated by Islamic medicine. With the support of the Chinese government, the first Traditional Chinese Medicine (TCM) center was established in 2000. However, due to safety issues, the management of the center had problems such as insufficient staff, limited medical experience, and non-persistentsupport. At present, TCM has not been included in the Iraqi medical insurance system, which has affected the people’s medical choice and hindered the development of TCM. It is recommended to strengthen the construction of existing TCM centers, improve the accessibility of TCM education, and strengthen the cooperation and exchanges of traditional medicine between the two countries to promote the spread and development of TCM in Iraq.
