Application prospect of new technology and new equipment in production of Chinese patent medicine / 中国中药杂志

At present,the production equipment and process of Chinese patent medicines still have many problems including high energy consumption,low efficiency,high pollution,and low intelligence,which seriously hinder the transformation,upgrading and modernized development of traditional Chinese medicine industry. With the emergence of various new pharmaceutical technologies and the application of technologies of other fields in traditional Chinese medicine industry,the development of Chinese patent medicine has ushered in new opportunities. The processes such as pulverization,mixing,extraction,separation,concentration,drying and sterilization are unique for the production of Chinese patent medicine. These main features can be distinguished from the manufacturing process of chemical drugs,determining the characteristics of the production process and equipment of Chinese patent medicine. In this paper,each operation unit was mentioned to summarize and analyze the new equipment and new technologies with advantages and characteristics in recent years from the perspectives of definition,principle,classification and application. Among them,the automatic spray device of the mixer,the extraction and separation equipment of volatile oil,and the crane basket-type circulation extraction technology,composite multi-layer spiral vibration countercurrent drying,and vibration sterilization equipment all have rapid development in recent years,with great prospects in the production of Chinese patent medicines. In this paper,we also analyzed some problems existing in the production equipment and technology of Chinese patent medicine and the key factors restricting the development of Chinese patent medicine,discussed the transformation of Chinese patent medicine production from traditional to modern and from semi-automatic to intelligent,and put forward three suggestions to help Chinese patent medicine achieve the goal of improving quality,efficiency and green manufacturing in production.

Impact of intensive insulin therapy on surgical critically ill patients / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluating the effect of different levels of blood glucose control on inflammatory response and prognosis of the patients in surgical intensive care unit (SICU).</p><p><b>METHODS</b>One hundred and eighty-eight patients admitted to SICU were randomly divided into three groups, blood glucose were controlled by insulin infusion. Group A (75 cases): the mean blood glucose (MBG) was maintained at the level of 4.4 - 6.1 mmol/L. Group B (75 cases): MBG was maintained at the level of 6.7 - 8.3 mmol/L. Group C (38 cases): MBG was maintained at the level of 10.0 - 11.1 mmol/L. Blood glucose control was achieved with an effected computerized protocol. The outcome was evaluated by days in ICU, days to wean mechanical ventilation, infection, amount of red blood cell transfusion, hospital mortality and ICU cost.</p><p><b>RESULTS</b>Compared with other groups, hypoglycemia (< 3.3 mmol/L) in Group A was significantly increased (P < 0.05). Compared with Group C, red blood cell transfusion and infection were significantly reduced in Group A and Group B (P < 0.05). Compared with Group C, days of mechanical ventilation and days in ICU in Group A were significantly reduced (P < 0.05). Hospital mortality and ICU cost were reduced in Group A compared with the other groups (P > 0.05).</p><p><b>CONCLUSIONS</b>To maintain blood glucose in normal range with intensive insulin therapy has potential positive impact on SICU patients' outcome and can reduce days in ICU and ICU cost. Further correlation research is needed to determine the best levels of blood glucose in ICU patients.</p>
