It has become a common consensus that resource conservation and intensive recycling for improving resource utilization efficiency is an important way to achieve carbon peak and carbon neutrality(dual carbon). Traditonal Chinese medicine(TCM)resources as national strategic resources are the material basis and fundamental guarantee for the development of TCM industry and health services. However, the rapid growth of China's TCM industry and the continuous expansion and extension of the industrial chain have exposed the low efficiency of TCM resources. Resource waste and environmental pollution caused by the treatment and discharge of TCM waste have emerged as major problems faced by the development of the industry, which has aroused wide concern. Considering the dual carbon goals, this paper expounds the role and potential of TCM resource recycling and circular economy industry development. Taking the typical model of TCM resource recycling as the case of circular economy industry in reducing carbon source and increasing carbon sink, this paper puts forward the suggestions for the TCM circular economy industry serving the double carbon goals. The suggestions mainly include strengthening the policy and strategic leading role of the double carbon goals, building an objective evaluation system of low-carbon emission reduction in the whole industrial chain of TCM resources, building an industrial demonstration park for the recycling of TCM resources, and promoting the establishment of a circular economy system of the whole industrial chain of TCM resources. These measures are expected to guide the green transformation of TCM resource industry from linear economic model to circular economy model, provide support for improving the utilization efficiency and sustainable development of TCM resources, and facilitate the low-carbon and efficient development of TCM resource industry and the achievement of the double carbon goals.

Under the precondition of ensuring safety and effectiveness, whether to reuse reprocessed medical devices to reduce the medical expenses has become the focus of the relevant regulatory authorities in our country. In this paper, we studied the regulatory policy for reprocessed medical devices in major international economies, such as United States, Japan, European Union and so on. From the regulatory and technical level, we thought about the risks of supervising reprocessed medical devices, and analyzed the ideas and risk concerns of supervising reprocessed medical devices to provide reference for regulation of such devices in our country.

BACKGROUND/AIMS: The prevalence of hepatitis C virus (HCV) infection in Busan, Gyeongnam, and Jeonnam Provinces in Korea is more than twice the national average. This study aimed to examine whether demographic and lifestyle characteristics are associated with HCV infection in these areas. METHODS: A case control study was performed at three study hospitals. HCV cases were matched with two controls for sex and age. Patient controls were selected from non-HCV patients at the same hospital. Healthy controls were subjects participating in medical checkups. Conditional logistic regression models were used. RESULTS: A total of 234 matched-case and patient- and healthy-control pairs were analyzed. The significant risk factors for both controls were sharing razors (adjusted odds ratio [aOR], 2.39 and 3.29, respectively) and having more than four lifetime sexual partners (aOR, 2.15 and 6.89, respectively). Contact dockworkers (aOR, 1.91) and tattoos (aOR, 2.20) were significant risk factors for the patient controls. Transfusion (aOR, 5.38), a bloody operation (aOR, 5.02), acupuncture (aOR, 2.08), and piercing (aOR, 5.95) were significant risk factors for the healthy controls. Needle stick injuries and intravenous drug abuse were significant in the univariate analysis. CONCLUSIONS: More education concerning the dangers of sharing razors, tattoos and piercings is required to prevent HCV infection. More attention should be paid to needle stick injuries in hospitals and the community.

This is a research project aimed at investigating the clinical efficiency of W-F168-B, a dialyzer reprocessing machine made by Weilisheng Biological Material Company in Chengdu, evaluating its effects on total cell volume (TCV) and dialysis sufficiency, and assessing its disinfection efficacy. All subjects were randomly divided into two groups, whose dialyzers were reprocessed by W-F168-B (made in Chengdu) and RENATRON II (made by MINNTECH Company in the United States) respectively. We detected TCV of the dialyzer before and after reusing and calculated their diversity. We also calculated all subjects' Kt/V. The values of TCV diversities of two groups were 5.5 +/- 4.15 (experimental group) and 4.5 +/- 2.56 (control group) respectively, P > 0.05. The levels of Kt/V of experimental group and control group were 1.25 +/- 0.26 and 1.24 +/- 0.19, P > 0.05. T-test showed that there was no statistically significance difference between the two groups. The result of every hemoculture is negative. In conclusion, these two dialyzer reprocessing machines are similar in the effect of the dialyzer's performance and the subject's dialysis sufficiency. The reused dialyzers reprocessed by these two machines are safe for use.

The aim of this study was to systemically analyze the proteins that adsorbed on the surface of hemodialysis membrane. The Fresenius F6 reused polysulfone dialyzers were selected as the research objects. The methodology we used encompassed the digestion of protein in rinsed solution and the separation of peptide mixture in virtue of RP-HPLC followed by ESI-MS/MS identification in orde to get their adsorption behavior, species and characteristics. The results illustrated that, after being rinsed by reverse osmosis (RO) water, 179 species of the protein adsorbed on the hemodialysis membrane, most of which were acidulous and middle or small weight protein molecules. The data from counting the numbers of peptides showed there were 5 species of high-abundant proteins (the contents being above 5% each), namely Ficolin-2 precursor, Complement C3 precursor (Fragment), Mannan-binding lectin serine protease 1 isoform 2 precursor, Complement-activating component of Ra-reactive factor precursor, and Mannan-binding lectin serine protease 1 isoform 3. These proteins are in close relationship with human immune system; moreover, they are of great significance to the clinical mechanism for cleaning reuse hemodialyzers and to the development of new hemodialysis materials.

Selecting reused polysulfone membrane (PSM) dialyzers as research objects, we mainly analyzed quantitatively the adhesion ingredients which obstructed the passage through the membrane, and we investigated the differences of residual contaminants on the surface of PSM in the cases of various reuse times. The results illustrated that after the completion of dialysis, the dialyzer was first cleaned by reverse osmosis (RO) water to remove the protein adsorpted. Then we used 2% sodium hypochlorite (NaClO) solution to soak it, and the glucose, cholesterol and triglyceride adsorpted were dissolved off. Meanwhile, the quantity of most of adsorption gradually increased with the increase of reuse times.

OBJECTIVETo explore the feasibility of replacement of ordinary syringes by auto-disposal syringes (AD) in China.
METHODSSampling survey was conducted in Hebei province to collect data on the direct medical spending of hepatitis B and their Disability Adjusted Life Year (DALY) losses. The financial burden on hepatitis B was calculated based on the result of field survey as well as through data-base of the Second National Health Services Survey of MOH in 1998. The cost-benefit analysis was employed, in which the saving of the financial burden on hepatitis B patients attributing to unsafe injections was taken as the benefit of intervention and the increased expenditures of AD syringes as the costs.
RESULTSThe total financial disease burden of Hepatitis B in China in 2001 was between RMB 16.19 and 20.17 billion Yuan and the financial disease burden per patient was between RMB 1755.38 and 1409.64 Yuan. Study on the cost-benefit analysis in the replacement intervention program showed high financial feasibility. The Benefit-Cost Ratio (BCR) of the measure was between 32.46 and 97.39, which was bigger in rural areas than that in cities. The direct BCR was less than one when the price gap between ordinary syringe and AD exceeded RMB 0.24 Yuan.
CONCLUSIONThe intervention of safe injection practice through universal usage of AD to replace ordinary syringe seemed to be applicable due to its high potential economic benefits.
