OBJECTIVE To investigate the methods of promoting nosocomial infection administration in laminar airflow(LAF) operation department,based on the theory of air microbe and object surface microbe. METHODS To begin with the construction standard of LAF operation department,to discuss difficult,complicating,professional and legal characteristics of nosocomial infection administration of LAF operating room. RESULTS It was a solid base of promoting nosocomial infection administrition to specify strictly the standard for the LAF operation department built;it was a vital link of promoting nosocomial infection administrition to take part in inspecting the engineering quality of LAF operation department;it is an effective means of LAF nosocomial infection administrition to carry out the supervision and control to the LAF operation department daily;it was the essense of promoting nosocomial infection administrition to make efforts to innovate the modern administration pattern in LAF operation department. CONCLUSIONS The management of hospital infection in the LAF operation department must emphasize the comprehensive measure of the all-directional germ control,make standard of decontamination of air conditioning guarantee system and carry out the whole process supervision.

Objective To summarize the nursing experience of 1 case of very low birth weight infant decannulation difficult in PICC. Methods The nursing key points included: full assessment analysis decannulation difficult reason, consult the PICC catheter outpatient health nurses, give magnesium sulfate hydropathic compress, mucopolysaccharide polysulfate cream local besmear outside, sanyrene outside, at the same time give low-molecular-weight heparin calcium injection subcutaneous injection such as anticoagulant active treatment and nursing. Results After 7 days ,the infant left axillary mass dispel, PICC pull out smoothly. Conclusions Decannulation difficult of very low birth weight infant requires full evaluation, multidisciplinary cooperation and specialist consultation, can give targeted personalized nursing safety smooth tube drawing, is worthy of reference for clinic.

Chinese materia medica(CMM) industry is one of the most national identity in China′s industries.According to the development situation in recent years,putting forward some reasonable ideas will promote better and faster development of the CMM industry.In this paper,through the literature review combined with CMM industry development status,the current structure of CMM industry was analyzed.And based on the concept of the industrial chain,the CMM industry chain structure was analyzed and described.The proposal of building a harmonious CMM industry chain was put forward clearly,which will conform to the requirements of the CMM industry development.Above all,this article has provided some constructive ideas for future development of CMM industry.

To investigate the current status of the postpartum weight retention (PPWR) in Kaifu District of Changsha, and explore the influential factors with PPWR based on the generalized estimating equation model.
 Methods: A cluster sampling method was applied to select women who gave birth at the health service centers of 3 street communities in Kaifu District of Changsha during 2015. According to the inclusion and exclusion criteria, 783 cases were finally included in the study. Data on PPWR were collected prospectively by using the self-made questionnaire at 1, 3, 6 and 8 months after childbirth. Analysis were performed to investigate the associations between PPWR and its potential factors with generalized estimation equation model.
 Results: The mean PPWR of women was gradually decreased with the increase of postpartum time, and 34.6% of them have returned to the pre-pregnancy weight in the 8 months postpartum. Our findings revealed that gestation weight gain (GWG), pre-pregnancy body mass index, feeding patterns, and delivery mode were significantly associated with maternal PPWR (P<0.05). In contrast, maternal age, educational level, per capita income of family, parity and postpartum depression were not contributed to PPWR (P>0.05).
 Conclusion: GWG is one of the most important predictors for PPWR. The key to reducing PPWR is to control GWG systematically. Early targeted interventions and health education should be taken to prevent women from excessive PPWR at the first-year postpartum, in particular to the women who underwent cesarean deliveries and breastfed their infants. It is conducive to reduce the risks of overweight or obesity caused by PPWR.
