Objective To investigate the effect of prophylaxis against respiratory and circulation depression caused by propofol during painless colonoscopy by intravenous doxpram with small dose.Methods 80 patients undergoing painless colonoscopy were randomly divided into the control group(A group) and the doxpram group(B group).All patients used propofol,and then used propofol after induction.In group B,doxpram was injected before anesthesia.The degree and incidence rate of respiratory and circulotion depression,the dose of propofol,the awake time,the examination time,the complication during anesthesia and awake were monitored.Results The SBP,DBP,SpO2,RR during anesthesia were obviously lower in group A than in group B(P

This experimental study was aimed to find the effect of different package and storage conditions on the content of effective components of A stragalus pieces. A stragalus pieces were stored under different storage conditions by using different packaging materials and packaging methods. Every three months, the contents of Calycosin-7-glu-coside and astragaloside were determined according to the 2010 version of Chinese Pharmacopoeia. With the extend-edstorage time, the contents of two effective components were significantly decreased. After six-monthstorage, the contents were not consistent with the standard of the pharmacopoeia standards. Room temperature had relatively big influence on the loss of content. The plastic and aluminum paperpackagingwere better than kraft paper packaging. The content ofastragaloside using non vacuum packaging method was relatively higher than the vacuum packaging. Contentunder the conditions of cool storehouse and nonvacuum plastic bags was higher than other packagingmethod. And the changes of both contents were relatively stable. It was concluded that the A stragaluspieces should be packed with non vacuum plastic bags, and stored in a cool and dry place.

Vocal fatigue（VF） is the common clinical symptom of voice diseases. It can also be a separate symptom and is considered to be a signal for the body to rest and to avoid pathological damage to the vocal cords. Therefore, the early identification and evaluation of vocal fatigue is of great value to the early prevention and treatment of vocal diseases. In recent years, there are many researches on the evaluation methods of vocalization fatigue. We searched the relevant literature and summarized the application status of vocal fatigue assessment methods, in order to provide reference for the selection and development of vocal fatigue assessment tools in clinical practice.

Objective:To evaluate the safety and efficacy of 27G micro-incision vitrectomy surgery (MIVS) combined with intravitreal injection of ranibizumab (IVR) in the treatment of retinopathy of prematurity (ROP) with early intervention failure.Methods:Retrospective case series was performed. Fourteen eyes (11 infants) with ROP who underwent 27G MIVS combined with IVR were included from March 2016 to January 2018 in Shenzhen Eye Hospital. Among them, there were 5 males with 7 eyes, 6 females with 7 eyes. The average gestational age of the infants was 28.12±0.90 weeks; the average birth weight was 1 023.64±200.96 g. Before the early clinical intervention, 1 infant (2 eyes) had ROP in zone Ⅰ stage 3 with plus disease, 8 infants (10 eyes) had ROP in zone Ⅱ stage 3 with plus disease, and 2 infants had ROP in aggressive posterior ROP. Six eyes underwent laser photocoagulation, while 8 eyes received laser therapy combined with IVR. Six eyes of stage 4A ROP and 8 eyes in stage 4B. Retinal detachment was detected with a mean of 10.44±9.21 weeks. At the time of surgery, the average post-conceptional age was 48.02±8.09 weeks. All the affected eyes were treated with standard sclera with three incisions 27G MIVS. During the operation, only local vitrectomy was performed to release and clear fibroascular proliferation in the optic disc, anterior macular area and pericristal area. After surgery, 10 mg/ml of ranibizumab 0.03 ml was injected into the vitreous cavity. The average follow-up time was 23.36±8.34 months. The primary objectives were the condition of retinal reset, ROP progression control and complications.Results:All patients had uneventful surgeries with an average duration of 32.86±9.35 mins. Of the 14 eyes, 12 eyes (85.71%) were controlled, 8 eyes (57.14%) had a good rearrangement of macular structure, while 4 eyes with macular traction. Two eyes had ROP progression, recurrence of retinal detachment, posterior synechia. Complicated cataract was in 1 eye. Proliferative vitreoretinopathy and retinal detachment was in 1 eye after 7 months the operation.Conclusion:27G MIVS combined with IVR is a safe and effective treatment for ROP with early clinical intervention failure.

OBJECTIVE：To establish the eva luation criteria for the rationality of tumor nutritional standardized treatment ，and to provide reference for nutritional standardized treatment in tumer patients . METHODS ：Based on domestic and foreign guidelines or expert consensus ，the rationality evaluation standard of tumor nutritional standardized treatmentwas formulated in our hospital （Bozhou Municipal People ’s Hospital ）. 50 nutritional treatment medical records in our hospital from Jan. to Jun. 2019 were evaluated by weighted TOPSIS ；according to the evaluation results ，nutritional intervention was carried out ，and 50 nutritional treatment medical records （group B ）from Aug. to Dec. 2019 were re-evaluated by the same method after intervention. RESULTS ： The established evaluation criteria for the rationality of tumor nutritional standardized treatment in our hospital included 18 indicators，such as malnutrition diagnosis ，description of the nature of malnutrition ，nutrition screening and evaluation ，etc. After analysis ，the rational rate of nutritional treatment was only 18％ in group A （Ci of ideal solution with 9 medical records≥0.6），and 78％ in group B （Ci of ideal solution with59 medical records ≥0.6）. There was statistical significance in the rationality of nutritional treatment before and after nutritional intervention （Ci≥0.6）（P＜0.05）. CONCLUSIONS ：The established rational evaluation method of tumor nutritional standardized treatment is feasible ，and the evaluation results are intuitive and reasonable. Nutrition intervention is helpful to reduce the irrational rate of nutritional treatment.
