Simiao Yong'an Decoction is derived from the New Compilation of Proved Prescriptions(Yan Fang Xin Bian). This formula has the effects of clearing heat and detoxifying as well as activating blood and relieving pain. It is mainly used to treat gangrene caused by excessive heat toxin and with the clinical manifestations including dark red and slightly swollen limbs, scorching skin, ulceration and odor, severe pain, occasional fever, thirst, red tongue, and rapid pulse. Nowadays, Simiao Yong'an Decoction is mostly used in the treatment of thromboangitis obliterans, ulcers in arteriosclerosis obliterans of lower limbs, stent restenosis after angioplasty of lower limbs, ecthyma, deep venous thrombosis, diabetic arteriosclerosis obliterans of lower limbs, diabetic foot ulcer, acute knee arthritis, varicose veins of lower limbs, coronary heart disease, post percutaneous coronary intervention(PCI), sepsis, gout, tumor, chronic tonsillitis in children, and other diseases. It has been identified that diabetic foot with infection, sepsis, arteriosclerosis obliterans, and thromboangitis obliterans belong to the category of gangrene in traditional Chinese medicine(TCM), and Simiao Yong'an Decoction is an ancient specialized prescription for treating this disease. The diseases that can be treated by Simiao Yong'an Decoction include arteriosclerosis obliterans, thromboangitis obliterans, diabetic foot, and ecthyma. The symptoms that can be treated by Simiao Yong'an Decoction include dark red, blackened, slightly swollen, burning, ulceration, and odor in the fingers and toes, and toes falling off, hands and feet decaying and collapsing, severe and unbearable pain in some cases. Furthermore, this formula is effective for skin ulceration spreading, pus dripping, swollen and proliferating lymph nodes. These symptoms are always accompanied by dry mouth, thirst, irritability, yellow urine, and dry stool. The TCM symptoms include red tongue, thin and white tongue coating, and wiry and rapid pulse. In the case with the complication of refractory hypotension, large dosage of Astragali Radix is used to replenish Qi, reinforce healthy Qi, and expressing toxin, which can often achieve blood pressure-elevating and anti-inflammatory effects. Simiao Yong'an Decoction is often combined with Simiao Pills and Guizhi Fuling Pills. High-dose medication is the key to the effectiveness of this formula. Integrated traditional Chinese and western medicine plays an important role in the treatment of diabetic foot with infection, sepsis, septic shock, arteriosclerosis obliterans, and thromboangitis obliterans.

Yuebi Plus Banxia Decoction is derived from the Synopsis of the Golden Chamber(Jin Gui Yao Lue) by ZHANG Zhong-jing. With the effects of ventilating lung, discharging heat, descending adverse Qi, and relieving cough and asthma, this prescription is mainly used to treat pulmonary distension caused by phlegm heat obstructing the lungs. Currently, it is commonly used in clinical practice for the treatment of acute exacerbation of chronic obstructive pulmonary disease, acute bronchitis, pneumonia, bronchial asthma, pulmonary heart disease, and pertussis. In the original text, lung distension refers to the inability of lung Qi to descend, including symptoms such as barrel chest, chest tightness, shortness of breath, coughing, and phlegm accumulation, and it is often seen in acute exacerbation of chronic obstructive pulmonary disease. The description of "the patient is panting and their eyes are likely to dislodge" indicates that Yuebi Plus Banxia Decoction is used to treat severe cases of pathogenic heat obstructing the lungs. The description of "the eyes are likely to dislodge" does not refer to hyperthyroidism with sunken orbits, but to the enlarged eye opening caused by severe coughing and asthma as well as chemosis caused by type Ⅱ respiratory failure. The disease indications of this prescription include acute exacerbation of chronic obstructive pulmonary disease, chronic obstructive pulmonary disease combined with type Ⅱ respiratory failure, severe pulmonary infection, pulmonary heart disease combined with infection, interstitial pneumonia, and bronchial asthma. The symptom and sign indications of this prescription include chest tightness, wheezing, cough, expectoration, yellow and sticky phlegm, difficult cough, dry mouth/thirst, desire for cold drinks, irritability, enlarged open of eyes, chemosis, dry stool, yellow urine, red tongue, thin white or yellow tongue coating, dry tongue coating, and floating and slippery powerful pulse. In terms of the disease nature, the indications of this prescription are mainly excess syndromes and rarely include deficiency syndromes. In terms of treatment course, one or two bags of Yuebi Plus Banxia Decoction can demonstrate effects of relieving dyspnea and coughing. In terms of prescription identification, Yuebi Plus Banxia Decoction needs to be distinguished from Yuebi Decoction and Yuebi Plus Atractylodes Macrocephala Decoction. In terms of pharmacological effects, Yuebi Plus Banxia Decoction demonstrates anti-inflammatory and antioxidant effects and can alleviate congestion and edema in the bronchial wall and surrounding interstitium.

Intestinal failure (IF) is defined as the critical reduction of functional intestines below the minimum needed to absorb nutrients and fluids, so that intravenous supplementation with parenteral nutrition (PN) is required to maintain health and/or growth. Although the benefits are evident, patients receiving PN can suffer from serious cholestasis due to lack of enteral feeding and small intestinal bacterial overgrowth (SIBO). One such complication that may arise is intestinal failure-associated liver disease (IFALD). Evidences from recent studies suggest that alterations in the intestinal microbiota, as well as intraluminal bile acid driven signaling, may play a critical role in both hepatic and intestinal injury. Since Marshall first proposed the concept of the gut-liver axis in 1998, the role of gut-liver axis disorders in the development of IFALD has received considerable attention. The conversation between gut and liver is the key to maintain liver metabolism and intestinal homeostasis, which influences each other and is reciprocal causation. However, as a "forgotten organ" , intestinal microbiota on the pathogenesis of IFALD has not been well reflected. As such, we propose, for the first time, the concept of gut-microbiota-liver axis to emphasize the importance of intestinal microbiota in the interaction of gut-liver axis. Analysis and research on gut-microbiota-liver axis will be of great significance for understanding the pathogenesis of IFALD and improving the prevention and treatment measures.

OBJECTIVES: To analyze the clinical characteristics of fecal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid-positive in patients with coronavirus dasease 2019 (COVID-19) and to provide a scientific basis for the prevention and control of this disease. METHODS: The clinical data of 16 patients with fecal SARS-CoV-2 nucleic acid positive, who hospitalized in the North Branch of the First Hospital of Changsha (Changsha Public Health Rescue Center) from January to February 2020, were retrospectively analyzed. Their clinical manifestations, laboratory data and imaging data were summarized. RESULTS: Among the 16 patients, there were 9 males (56.25%) and 7 females (43.75%), the ratio of males to females was 1∶1.29. The age of onset was (43.3±14.6) years. There were 15 patients with contact history of Wuhan, 1 patient with contact history of local patient.Twelve patients were common type (75%), and 4 patients were severe type (25%). Clinical symptoms included fever in 14 patients (87.5%), cough in 12 patients (75%), shortness of breath in 5 patients (31.25%), pharyngalgia in 10 patients (62.5%), fatigue in 7 patients (43.75%), and diarrhea in 4 patients (25%). There were 14 patients (87.5%) with normal or decreased white blood cell count, 11 patients (68.75%) with decreased lymphocyte count, 15 patients (93.75%) with increased erythrocyte sedimentation rate, 13 patients (81.25%) with increased hypersensitivity C-reactive protein, 5 patients (31.25%) with increased procalcitonin, and 8 patients (50%) with increased serum ferritin in peripheral blood, and stool routine was basically normal. Compared with the common type, there was significant difference in the white blood cell and lymphocyte counts in the severe type (<0.01); the infection indicators, such as hypersensitivity C-reactive protein and serum ferritin, were significantly increased, with significant difference (all <0.01); but the procalcitonin and erythrocyte sedimentation rate was not significantly different (both >0.05). Chest CT mainly showed patchy shadows and interstitial changes. According to imaging examination, 4 patients (25%) showed unilateral pneumonia and 12 patients (75%) showed bilateral pneumonia. CONCLUSIONS The patients have the clinical symptoms of COVID-19, but gastrointestinal symptoms (such as diarrhea) are more common, and the changes of white blood cell count, lymphocyte count, hypersensitivity C-reactive protein, ferritin are more obvious in severe patients.The positivity of fecal nucleic acid suggests the possibility of digestive tract transmission of SARS-CoV-2, and fecal nucleic acid testing can be used as a routine testing method in clinical practice.

OBJECTIVES: To analyze the clinical characteristics in patients of coronavirus disease 2019 (COVID-19) complicated with liver injury, to explore the relationship between COVID-19 clinical classification and liver injury, and to elucidate whether COVID-19 complicated with hepatitis B virus can aggravate liver injury. METHODS: The abnormal liver function in 110 patients in the First Hospital of Changsha, who were confirmed COVID-19 and admitted to the designated hospital from January 17, 2020 to February 20, 2020, wereretrospectively analyzed. The detection indexes included serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBIL). RESULTS: A total of 49.1% of the COVID-19 patients had liver injury. There were significant difference in the ALT, AST, ALB (all <0.05), but there was no significant difference in the TBIL (>0.05) between the severe (critical) patients and the general (light) patients. There was also no significant difference in the liver function injury between the HBsAg-positive COVID-19 patients and HBsAg-negative COVID-19 patients (>0.05). Acute liver injury was not found to be a direct cause of death in the patients. CONCLUSIONS In the COVID-19 patients, the incidence of liver injury is high with the increase of ALT and AST and the decrease of ALB. Severe and critical patients have obvious liver injury, and those patients complicated with hepatitis B virus infection don't show aggravated liver injury.

OBJECTIVES: To investigate the clinical characteristics and risk factors for severe events of coronavirus disease 2019 (COVID-19) in elderly patients. METHODS: Retrospective analysis was performed on the clinical data of all elderly COVID- 19 patients treated in Changsha Public Health Treatment Center from January 17, 2020 to March 15, 2020, which included basic diseases, symptoms, test results, and other clinical characteristics, and prognostic indicators such as severity of illness, length of hospital stay, virus shedding time and mortality rate. The differences in clinical characteristics and prognostic indicators between elderly, middle-aged, and young COVID-19 patients were also analyzed. Logistic regression model was used to conduct univariate and multivariate analysis of risk factors for developing severe events in elderly COVID-19 patients; receiver operating characteristic (ROC) curve analysis was used to evaluate the prediction efficacy. RESULTS: Of the 230 COVID-19 adult patients, 34 were young patients (14.8%), 136 were middle-aged patients (59.1%), and 60 were elderly (26.1%). Among the 60 elderly patients, 23 were male (38.3%) and 37 were female (61.7%), with a medium age of 66 years old. Common symptoms were fever (66.7%), cough (50.0%), and fatigue (41.7%). C reactive protein (CRP) was increased significantly. The proportion of severe cases was 31.7%, and mortality was 1.7%. The median length of hospitalization and median virus shedding time were 18.5 days and 21 days, respectively. Compared with the young and the middle-aged patients, the elderly had a higher proportion of hypertension, diabetes, and cardiovascular diseases, more common shortness of breath, higher proportions of pneumonia and severe cases (all <0.05), and the decreased lymphocyte count and lymphocyte percentage (both <0.05), as well as higher CRP and erythrocyte sedimentation rate (ESR) levels (both <0.05). Compared with non-severe cases, severe elderly patients demonstrated higher CRP and aspartate aminotransferase (AST) levels (all <0.05), the reduced lymphocyte count (<0.05), and the prolonged length of hospitalization and virus shedding duration (both <0.05). Univariate logistic regression analysis indicated that the lymphocytes proportion, CRP and AST levels were significantly correlated with the risk for developing severe events in elderly COVID-19 patients (all <0.05). Multivariate logistic regression found that severe events in elderly patients with COVID-19 were significantly correlated with CRP level (OR=1.041, =0.013). ROC curve analysis revealed that the area under the curve (AUC) for CRP to diagnose severe events in elderly COVID 19 patients was 0.851. CONCLUSIONS The proportion of severe cases in elderly COVID-19 patients is higher than that in young and middle-aged patients. CRP level has a good predictive value for the possibility of severe events in elderly COVID-19 patients.

OBJECTIVES: Since the outbreak of coronavirus disease 2019 (COVID-19), it has spread rapidly in China and many other countries. The rapid increase in the number of cases has caused widespread panic among people and has become the main public health problem in the world. Severe patients often have difficult breathing and/or hypoxemia after 1 week of onset. A few critically ill patients may not only rapidly develop into acute respiratory distress syndrome, but also may cause coagulopathy, as well as multiple organs failure (such as heart, liver and kidney) or even death. This article is to analyze the predictive role of clinical features in patients with COVID-19 for severe disease, so as to help doctor monitor the severity-related features, restrain the disease progress, and provide a reference for improvement of medical treatment. METHODS: The clinical data of 208 patients with COVID-19 who were isolated and treated in Changsha Public Health Treatment Center from January 17, 2020 to March 14, 2020 were collected. All patients were the mild and ordinary adult patients on admission, including 105 males and 103 females from 19 to 84 (median age 44) years old. According to the "Program for the diagnosis and treatment of novel coronavirus (COVID-19) infected pneumonia (Trial version 7)" issued by the General Office of National Health Committee and Office of State Administration of Traditional Chinese Medicine as the diagnostic and typing criteria. According to progression from mild to severe disease during hospitalization, the patients were divided into a mild group (=183) and a severe transformation group (=25). The clinical features such as age, underlying disease, blood routine, coagulation function, blood biochemistry, oxygenation index, and so on were analyzed. Among them, laboratory tests included white blood cell (WBC), lymphocytes (LYM), neutrophil (NEU), hemoglobin (Hb), platelet (PLT), prothrombin time (PT), plasma fibrinogen (Fib), activated partial prothrombin time (APTT), thrombin time (TT), -dimer, total bilirubin (TBIL), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), serum creatinine (Cr), creatine kinase (CK), creatine kinase isoenzyme-MB (CK-MB), lactate dehydrogenase (LDH), C-reactive protein (CRP), and oxygen partial pressure in arterial blood. Partial pressure of oxygen in arterial blood/fractional concentration of inspiratory oxygen (PaO/FiO) was calculated. The variables with statistical significance were analyzed by logistic regression analysis. RESULTS: Patients in the severe transformation group had more combined underlying diseases than those in the mild group (<0.05). From the perspective of disease distribution, patients in the severe transformation group had more combined hypertension (<0.05). In the severe transformation group, PT was significantly longer, the levels of Fib, ALT, AST, CK, LDH, and CRP were significantly higher than those in the mild group (<0.05 or <0.001), while LYM, ALB, and PaO/FiO were significantly lower than those in the mild group (<0.05 or <0.001). Logistic regression analysis was performed on clinical features with statistically significant differences. Combined with hypertension, LYM, PT, Fib, ALB, ALT, AST, CK, LDH, and CRP as independent variables, and having severe disease or not was the dependent variable. The results show that combined hypertension, decreased LYM, longer PT, and increased CK level were independent risk factors that affected the severity of COVID-19 (<0.05). CONCLUSIONS The patients with mild COVID-19 who are apt to develop severe diseases may be related to combined hypertension, decreased LYM, and longer PT, and increased CK level. For the mild patients with these clinical features, early intervention may effectively prevent the progression to severe diseases.

OBJECTIVES: To explore the significance of coagulation and immune function indicators in clinical diagnosis and treatment of coronavirus disease 2019 (COVID-19). METHODS: All patients with COVID-19 diagnosed and treated in First People's Hospital of Yueyang from January to March 2020 were enrolled. The general data of patients were collected. The patients were assigned into a light group (=20), an ordinary group (=33), a severe group (=23), and a critically severe group (=7) according to the severity of the disease. Coagulation and immune function indicators of each group were compared, and the relevance of coagulation and immune function indicators was analyzed. RESULTS: The age of COVID-19 patients in Yueyang City was mainly between 45 and 65 years old. There was a significant difference in the coagulation function and immune-related indicators in each group of patients (all <0.05). CONCLUSIONS There are some abnormalities in coagulation and immune function in patients with COVID-19, which possess significance for clinical diagnosis and treatment of the disease.

OBJECTIVES: To analyze the clinical characteristics of 71 patients with coronavirus disease 2019 (COVID-19). METHODS: The general data, epidemiological data, laboratory tests, imaging examinations, and treatment of 71 patients with COVID-19 admitted to the Sixth People's Hospital of Zhengzhou from January 19, 2020 to March 3, 2020 were retrospectively analyzed. RESULTS: Of the 71 COVID-19 patients, the ages were 4-84 (41.29±15.21) years, 38 (53.5%) patients were male, 33 (46.5%) were female, and 52 (73.2%) were in 22 clusters. The main clinical manifestations were fever (78.9%), cough (64.8%), and sputum (38.0%). The fever was mainly low and moderate, with 49 patients (69.0%) at 37.3-39.0 ℃. Most of the leukocytes, neutrophils, and lymphocytes were normal, accounting for 47 (66.2%), 51 (71.8%), and 51 (71.8%) patients, respectively; a few of them were decreased, accounting for 21 (29.6%), 16 (22.5%), and 20 (28.2%) patients, respectively. There were 38 (53.5%) and 31 (43.7%) patients with the decreased CD4 and CD8 T cell counts, respectively. There were 41 (57.7%), 38 (53.5%), 32 (45.1%), 26(36.6%), 22 (31.0%), 20 (28.2%), 14 (19.7%), 14 (19.7%), and 9 (12.7%) patients with the increased levels of C-reactive protein, erythrocyte sedimentation rate, procalcitonin, fibrinogen,interleukin 6, lactate dehydrogenase,-dimer,alanine aminotransferase, and aspartate aminotransferase, respectively. Of the 71 patients, the lung was involved in 60 (84.5%) patients, the double lung was involved in 47 (66.2%) patients, and the single lung was involved in 13 (18.3%) patients. The course of the disease was long, and the time from symptom onset to the second severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid negative transformation was (17.22±6.34) days.There were no significant differences in the incubation period (=-0.453, >0.05), the complicates (χ=0.042, >0.05), and the time from symptom onset to diagnosis (=-1.330, >0.05) in patients between the non-severe group and the severe group. The onset age, gender, SARS-CoV-2 nucleic acid negative time, lymphocyte count, -dimer, C-reactive protein, total bilirubin, direct bilirubin, lactate dehydrogenase, calcium ion, CD4 T cell count, CD8 T cell count, calcitonin, procalcitonin, and troponin were significantly different between the severe group and the non-severe group (all <0.05). Among the 71 patients, 4 (5.6%) patients were mild, 59 (83.1%) were normal, and 8 (11.3%) were severe or critical. CONCLUSIONS The aggregation phenomenon of COVID-19 is obvious. Fever and cough are the main clinical manifestations. White blood cells, neutrophils, and lymphocytes in the most patients in the early onset are normal. Most COVID-19 patients are light and ordinary type, with good prognosis.
