Expert consensus on diagnosis and treatment of ulcerative colitis with integrated traditional Chinese and Western medicine:A nursing perspective

Ulcerative colitis(UC)is a chronic nonspecific intestinal inflammatory disease of unclear etiology,characterized by continuous and diffuse inflammatory changes of colorectal mucosa.In recent years,the incidence rate of UC in China has increased year by year,but there is no effective cure method in Western medicine.Traditional Chinese medicine treatment based on syndrome differentiation has the unique advantages of simplicity,convenience,effectiveness,and low cost.Therefore,integration of Chinese and Western medicine has become an important strategy for UC diagnosis and treatment,and has made significant progress in UC.On the basis of learning from a number of consensuses at home and abroad,combined with Chinese research results and the actual clinical situation of traditional Chinese and Western medicine,the UC group of the Chinese Association of Integrative Medicine has formulated the expert consensus on the diagnosis and treatment of UC with integrated traditional Chinese and Western medicine.In this consensus,the pathogenesis,etiology and pathogenesis,diagnosis,integrated traditional Chinese and Western medicine treatment,and chronic disease management with integrated traditional Chinese and Western medicine for UC were recommended by experts.This article interprets the consensus from the perspective of nursing in order to provide reference basis for clinical nursing workers.

High biomass yields of Chlorella protinosa with efficient nitrogen removal from secondary effluent in a membrane photobioreactor

Further treatment of secondary effluents before their discharge into the receiving water bodies could alleviate water eutrophication.In this study,the Chlorella proteinosa was cultured in a membrane photobioreactor to further remove nitrogen from the secondary effluents.The effect of hydraulic retention time(HRT)on microalgae biomass yields and nutrient removal was studied.The results showed that soluble algal products concentration reduced in the suspension at low HRT,thereby alleviating microalgal growth inhibition.In addition,the lower HRT reduced the nitrogen limitation for Chlorella proteinosa’s growth through the phase-out of nitrogen-related functional bacteria.As a result,the productivity for Chlorella proteinosa increased from 6.12 mg/L/day at an HRT of 24 hr to 20.18 mg/L/day at an HRT of 8 hr.The highest removal rates of 19.7 mg/L/day,23.8 mg/L/day,and 105.4 mg/L/day were achieved at an HRT of 8 hr for total nitrogen(TN),ammonia,and chemical oxygen demand(COD),respectively.However,in terms of removal rate,TN and COD were the largest when HRT is 24 hr,which were 74.5%and 82.6%respectively.The maximum removal rate of ammonia nitrogen was 99.2%when HRT was 8 hr.
