Improvement of China's legal system for public health emergency management from the perspective of lifecycle management / 中华流行病学杂志

A crucial lesson gained through the pandemic preparedness and response to COVID-19 is that all measures for epidemic control must be law-based. The legal system is related not only to public health emergency management per se but also to all aspects of the institutional supporting system throughout the lifecycle. Based on the lifecycle emergency management model, this article analyses the problems of the current legal system and the potential solutions. It is suggested that the lifecycle emergency management model shall be followed to establish a more comprehensive public health legal system and to gather the intelligence and consensus of experts with different expertise, including epidemiologists, sociologists, economists, jurist and others, which will collaboratively promote the science-based legislation in the field of epidemic preparedness and response for the establishment of a comprehensive legal system for public health emergency management and with Chinese characteristics.

[Effects of enrofloxacin and Cu combined pollution on the activities of digestive enzymes of earthworm in soil.] / æ©è¯ºæ²™æ˜Ÿå’Œé“œå¤åˆæ±¡æŸ“å¯¹èš¯èš“æ¶ˆåŒ–é ¶æ´»æ€§çš„å½±å“.

The effects of single and combined pollution of enrofloxacin and Cu on the digestive enzymes of earthworms were studied, based on the actual pollution of caused by the application of livestock feces in farmland soil. Results showed that single enrofloxacin (0.1-4 mg·kg-1, 28 d) did not affect protease, but inhibited cellulase and alkaline phosphatase, with an induced effect on acid phosphatase. Single Cu pollution (20-200 mg·kg-1, 28 d) had inhibitory effects on the four digestive enzymes in earthworms. The effects of combined exposures on the digestive enzymes were mainly negative, showing a synergistic increasing character of toxicity in cellulase and acid phosphatase activities. The response dynamics of digestive enzymes to exposure duration was regulatory response (3 d)-intense response (7 d)-reaction recovery (14 d)-chronic exposure (28 d). Chronic exposure results showed that the combined treatments containing high-dose pollutant (200 mg·kg-1 Cu or 4 mg·kg-1 ENR) had more ecological risk.

Efficacy observation on navel-warming therapy combined with western medication for yang-deficiency tympanites / 中国针灸

<p><b>OBJECTIVE</b>To observe the effects of navel-warming therapy on clinical efficacy in patients with yang-deficiency tympanites based on regular treatment of western medication.</p><p><b>METHODS</b>One hundred and twenty cases of yang-deficiency tympanites were randomly divided into a navel-warming therapy group and a western medication group, sixty cases in each one. The regular treatment of western medicine was applied in the western medication group, including oral administration of antiviral drug and diuretics as well as intravenous drip of hepatic protector. Based on western medicine treatment, the navel-warming therapy was applied in the navel-warming group. A medical cake was laid on Shenque (CV 8), and then a medical cylinder was placed above the medical cake and ignited. The treatment was given once daily. One month was considered as a treatment session in both groups and totally one session was required. The TCM symptom score, B-ultrasound ascites and temporary use of diuretics before and after treatment were observed in both groups; also the efficacy was evaluated.</p><p><b>RESULTS</b>The total effective rate was 81.7% (49/60) in the navel-warming therapy group, which was superior to 56.7% (34/60) in the western medication group (P < 0.05). After the treatment, the TCM symptom score and ascites were improved in both groups (all P < 0.05), which was more significant in the navel-warming therapy group (all P < 0.05). The temporary use of diuretics was statistically different between the two groups (P < 0.05), indicating the navel-warming therapy group could obviously reduce or stop the use of diuretics.</p><p><b>CONCLUSION</b>Based on regular treatment of western medication, the navel-warming therapy could significantly improve therapeutic efficacy, effectively relieve clinical symptoms and ease ascites.</p>
