Objective: To study the interaction anxiousness status of new recruits in Chinese People's Armed Police Force.Methods: 981 recruits were assessed with Interaction Anxiousness Scale(IAS).Results: The average score of IAS of recruits was 42.93?7.35.There was higher social anxiety level in the recruits who graduated from junior middle school than those who graduated from senior high school.There were respectively 37.5% and 39.3% of recruits feeling uneasy when they were in contacting with strangers and talking with supervisors.There were 85.5% of recruits lacking confidence.Conclusion: The level of interaction anxiousness of new recruits was relatively high,it embodied contacting with strangers,talking with supervisors and lacking confidence.

OBJECTIVE: To investigate the synergistic cytotoxicity of TRAIL and paclitaxel on nasopharyngeal cell lines CNE-1 and CNE-2. METHOD: CCK-8 assays the growth inhibition rate of CNE-1 and CNE-2 which was treated with TRAIL or paclitaxel or combination of both. Flow cytometry tests the apoptosis rate of CNE-1 and CNE-2 which was treated with TRAIL or paclitaxel or combination of each other. RESULT: In certain range of time and concentration,TRAIL and paclitaxel inhibited the growth of the cell lines of CNE-1 and CNE-2 in a time-dose dependent manner (P < 0.05). The rate of growth inhibition and apoptosis in TRAIL and paclitaxel combinative group was more significant than that in the TRAIL and paclitaxel singular group (P < 0.05). CONCLUSION TRAIL and paclitaxel had a synergistic killing effect on NPC cell lines and showed better affection than singular group, which provides a novel and prospective strategy for NPC chemotherapy.

In order to improve the success rate of supraclavicular deep venous catheterization and reduce mechanical complications, we present an auxillary maneuver in regard to supraclavicular subclavian catheterization basing on the relatively fixed anatomy of subclavian vein and its adjacent surroundings, furthermore, we revised the standardized procedure of supraclavicular subclavian catheterization. The maneuver is summarized in the shape of verses (verses: thumb navigation is well designed according to anatomy. Needle penetrated into vein should be parallel to coronal plane. Fine needle in position should be immobilized. Is it difficult for parallel puncture? Pressure determination is required when needle is in place. It is critical to distinguish which vessel has been inserted. Guidewire is advanced smoothly. Check blood return after expansion of skin and catheterization.). For teaching convenience, verses are considered to be more concise and memorable, as well as applicable to clinical practice, in order to provide some help for clinical teaching.

To improve the effectiveness of bedside localization of nasointestinal tube(NIT)and facilitate the placement of nasointestinal tube into jejunum,we established a procedure and composed a teaching verse for bedside placement of nasointestinal tube based on relevant classical literature and our own practices.Verse content:enteral nutrition means a successful strategy to improve the outcome in critically ill patient management,never hesitate to place nasointestinal tubes when necessary.There are several methods to deal with it,but popularizing it remains a long way off.Half-sitting and swallowing into the esophagus,freely withdrawing signifies the stomach cavity.Passing through the pylorus using light tension on the tube in the right lateral decubitus position.Arriving at the jejunum with low resistance in the left lateral decubitus position.What are the signs of intragastric coiling?Tube return out of nose is the initial observation,Failure of air insufflation indicates tube coiling.Dyeing location surpasses imaging.Vacuum test is the most sensitive,Sequential change from acid to base is specific.Methylene blue test is dramatical for localization.Combining three methods is enough to navigate.Abdominal plain film is the goldan standard and can still be used in ultrasonic era.3-D image establishes overall view.CT reveals the tube route exactly.The teaching verse has become a powerful tool for clinical teaching of manual nasointestinal tube placement in a concise and easy-to-remember form.
