In drought years, most residents fail to improve water use efficiency due to residential water supply normally being prioritized in many regions, which makes other low-priority industrial water users suffer more from water shortage. This paper proposes a Pricing Strategy for Residential Water (PSRW), a water tariff that changes on annual time scale, based on the scarcity value of water resources, aiming to promote residential water conservation and reallocate water resources across the residential and industrial sectors during droughts. An optimization model to maximize the total benefit of residents and industrial sectors is introduced based on marginal benefit and price elasticity. The water shortage of industrial sectors is used to reflect the scarcity of water resources, and the lowest water supply standard for households and the maximum proportion of household water fee expenditure (HWFE) to household disposable income (HDI) are used to ensure the residents’ acceptability to price raising. It shows an “S-type” relationship between the optimal price raising coefficient and industrial water shortage, and two turning points are found in the curve, which are the starting and stopping points of price raising. The appearance of starting point depends on the non-negative net benefit, and the stopping point is affected by the factors that represent the residents’ acceptability to price raising. The application to Tianjin, a city in northern China with the rapid growth of population and economy but scarce water resources, shows PSRW is a potential means to improve water efficiency and optimize water resource allocation in water scarcity situations.
In recent years, with the progress and development of the times, our eating habits and lifestyle changes have led to an increase in gouty arthritis annually, with the main use of nonsteroidal anti-inflammatory drugs and other drugs. These drugs are highly dependent, resulting in an unresponsive state, which is easy to recur. Therefore, more and more patients choose traditional Chinese medicine (TCM) to treat them. After years of continuous exploration and rich clinical experience accumulation, Academician TongXiaolin put forward the dialectical strategy of “combination of state and target” in TCM. He believed that the deficiency of liver and kidney is transformed into a state, with uric acid as the target. Through the target prescription Simiao decoction to clever heat and moisture, replenishing liver and kidney, the target medicine Bixie (Dioscorea Tokoro Makino) to rheumatism, Shujin;Tufuling (Rhizoma Smilacis Glabrae) for detoxification, dehydration gas, Weilingxian (Radix et Rhizoma Clematidis) to rheumatism, pass meridians, and the combination of the condition and target achieves a good clinical effect.
Objective To investigate the incidence and characteristics of scoliosis among middle school students and adolescents in Haicheng City, Liaoning Province, to enrich the epidemiological data of the disease in our city and provide theoretical basis for clinical prevention and treatment.
Methods From October 10, 2019 to December 12, 2019, under the organization of the Haicheng Education Bureau of Liaoning Province, students from 37 schools in the city’s junior and senior high schools were screened, and all the subjects were tested in turn. Screening methods, namely the
first inspection visual method, Adam bending test, second inspection scoliosis measurement rulers, third inspection standing position spine full length anterolateral X-ray examination. X-ray examination found that Cobb’s angle ≥10° The patient was diagnosed with scoliosis. Results
the number of students screened in this screening were 29,314, and the number of confirmed cases was 289 (0.99%). Among the confirmed numbers were 115 males (39.79%) and 174 females (60.21%). The prevalence of females was higher than that of males (X2=27.789). P=0.0000). Among the confirmed
cases, 245 cases had Cobb’s angle ≤19°, 28 cases had Cobb’s angle 20°−29°, 10 cases had Cobb’s angle 30° − 39°, and 6 cases had Cobb’s angle ≥40°. Conclusion The incidence of scoliosis among middle school students in Haicheng
City, Liaoning Province is higher in the junior high school group than in the high school group. The incidence of female students is higher than that of male students, which should be taken seriouslt.
