The liver in the traditional Chinese medicine (TCM) theory of visceral manifestation has rich connotations. Thestructure and function of liver differed from that of liver in modern recognition. Research on TCM theory has partiallyexplained the liver theory. The function of controlling dispersion of liver was associated with neuro-endocrine-immunesystem, liver sinus endothelial function, and metallothionein, etc. While the activity of storing blood of liver related withblood coagulation factors, anticoagulant and so on. The functional interaction between Zang-organ and Fu-organ maycorrelate with the lung-liver axis and liver-intestine axis. The review summarized the modern explanation on liverfunction in TCM and its relationship with Fu-organs to help the development of TCM basic theory in liver function.

Objective:To explore the relationship between weight change and metabolic control of type 2 diabetic patients after 1 year treatment under the standardized metabolic disease management model.Methods:From November 2017 to November 2021, 950 patients with T2DM in the Standardized Metabolic Management Center of Suzhou Municipal Hospital were recruited in this research, who were divided into normal(BMI 18.5-23.9 kg/m 2), overweight(BMI 24.0-27.9 kg/m 2), and obese(BMI≥28 kg/m 2)groups according to baseline BMI. The metabolic indicators and control rates were compared. The overweight and obese 599 patients were divided into weight reduction(<-3 kg), maintenance(-3-1 kg) and gain(>1 kg)groups according to weight changes by one year, and metabolic indicators and control rates were compared to analyze the influence of weight change on metabolic control of overweight and obese patients. Results:(1) The overweight and obese groups had worse metabolic control at baseline and the obese group was younger. After 1 year, the metabolic indicators of three groups were significantly improved. (2) After 1 year, the metabolic control was better in weight reduction group and worse in weight gain group. The control rates were increased in weight reduction and maintenance groups. (3) For every 1 kg reduction in body weight of overweight and obese patients, blood glucose, blood lipids, blood pressure and comprehensive control rate increased by 1.206, 1.046, 1.069 and 1.107 times, respectively. There was a positive linear relationship between weight reduction and metabolic improvement.Conclusion:Standardized metabolic disease management model promotes metabolic control in type 2 diabetic patients, especially in overweight and obese patients who actively lose weight. In the future we should strengthen the management of overweight and obese patients, enhance self-management ability, and manage body weight scientifically and effectively.

Objective:To investigate the application value of auricular point pressing with beans combined with Chinese medicine for rehabilitation in older adults after total hip arthroplasty.Methods:This is a prospective case-control study. A total of 80 older adult patients with femoral neck fractures who underwent total hip arthroplasty at Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from September 2020 to January 2022 were included in this study. These patients were randomly divided into a control group and an observation group, with 40 patients per group. The control group underwent conventional interventions, while the observation group underwent auricular point pressing with beans combined with Chinese medicine. Clinical efficacy was compared between the two groups.Results:The overall response rate in the observation group was 85.00% (34/40), which was significantly higher than 65.0% (26/40) in the control group ( χ2 = 4.27, P = 0.036). Before surgery, there were no significant differences in various indicators between the two groups (all P > 0.05). At 2 weeks after surgery, the hemoglobin level and Harris scores in the observation group were higher than those in the control group ( t = -7.11, -5.81, both P < 0.05). At 1 and 3 days and 2 weeks after surgery, the D-dimer level, prothrombin time, activated partial thrombin time, thrombin time, Visual Analogue Scale score, and Pittsburgh Sleep Quality Index (PSQI) in the observation group were significantly lower than those in the control group (all P < 0.05). At 3 days and 2 weeks after surgery, C-reactive protein, thigh and calf circumference of the affected limb in the observation group were significantly lower than those in the control group ( t = 2.34, 6.85, 4.47, 3.89, 6.63, 4.35, all P < 0.05). After surgery, the time to get off the bed and the length of hospital stay in the observation group were (3.58 ± 2.43) days and (7.14 ± 2.18) days, respectively, which were significantly shorter than (5.47 ± 2.35) days and (9.13 ± 2.14) days in the control group ( t = 3.54, 4.12, both P < 0.001). The incidence of postoperative deep vein thrombosis in the observation group was 5.00% (2/40), which was significantly lower than 10.00% (4/40) in the control group ( χ2 = 0.72, P = 0.396). Conclusion:Auricular point pressing with beans combined with Chinese medicine can promote rapid rehabilitation of older adult patients with femoral neck fractures after total hip arthroplasty.

Objective To describe and analyze the disease burden and its changing trend of liver cancer caused by nonalcoholic steatohepatitis (NASH) in China from 1990 to 2019, and to provide reference for reducing the morbidity and mortality of liver cancer in China. Methods Based on data from the Global Burden of Disease (GBD2019) study, different gender and age groups were selected. The morbidity, mortality, and disability adjusted life year (DALY) rate were used to analyze the disease burden of liver cancer caused by NASH in China from 1990 to 2019. The time trend was analyzed by using the Joinpoint regression model, and the annual percent of change (APC) and annual average percentage change (AAPC) of morbidity, mortality and DALY rate were calculated. Results Compared with 1990, the incidence rate, mortality rate and DALY rate of liver cancer caused by NASH in 2019 decreased by 4.05%, 12% and 25.79%, respectively. Age-standardized morbidity, standardized mortality and standardized DALY rates decreased by 49.50%, 54.72% and 58.45%, respectively. In 2019, the incidence rate, mortality data and DALY rate of liver cancer caused by NASH increased with age, and the highest mortality rate was among people over 85 years old. The average annual change percentage (AAPC) of age-standardized incidence rate, standardized mortality rate and standardized DALY rate of liver cancer caused by NASH from 1990 to 2019 were -2.65% [95% CI(-3.09%,-2.21 %),P<0.001], -2.86%[95% CI(-3.34%,-2.38 %),P<0.001], and -2.91%[95% CI(-3.23%,-2.58%),P<0.001],respectively. The AAPC of all indexes in males was higher than that in females. Conclusion From 1990 to 2019, the disease burden of liver cancer caused by NASH in China showed an overall downward trend. The AAPC of all indexes in males is higher than that in females, and the elderly population is a high-risk group.
