OBJECTIVE To investigate rate,cause,psychology and prevention of needle-stick injuries among nursing staff.METHODS A retrospective questionnaire was distributed to a convenience sample of 426 clinical nurses in a hospital.RESULTS Totally 379 nurses(88.97%) suffered from needle-stick injuries with an average of 4.75 times per person annually.The nurses with needle-stick more than 10 times accounted for 6.10%.The main reasons of needle-stick included pulling needles,adding medication,separating needle and so on.CONCLUSIONS Nurse should consolidate them self-protective consciousness.Therefore,it is a very important task of occupational prevention to improve the education of concept of universal precautions,prevent needle stab and reduce the occurrence of blood born diseases.

Objective: to investigate the effect of Radix Astragali(黄芪) Injection and moxibustion on white blood cell amount and cellular immunity in patients with post-chemotherapy leukopenia. Methods: eighty-six cases of post-chemotherpy leucopenia were allocated into group of acupoint injection with Radix Astragali(黄芪) plus mild moxibustion with moxa stick(treatment group) and group of westerm medicine orally took(control group), and the clinical symptoms, white blood cell amount, and the change of CD+3、CD+4and CD+8 before and after the treatment were observed. Results: acupoint injection with Radix Astragali(黄芪) plus mild moxibustion with moxa stick could enhance the white blood cell amount more markedly than western medicine. The former could increase the contents of CD+3 and CD+4, and promote the ratio of CD+4/CD+8 of the patients with tumor, meanwhile, improve the general weak, and there is a significant different between the two groups(P<0.01).

Objective To find out households consumption of iodized salt in Xinjian county, and to provide scientific basis for prevention and treatment of iodine deficiency disorders(IDD). Methods From 2006 - 2010 in Jiangxi province, according to the direction of east, west, south, and north, nine townships(streets) were selected,in each township (street), 4 administrative villages (committees) were selected, in each administrative village(committee) 8 households were selected to collect their edible salt each year, direct titration method was adopted to detect salt iodine. Results From 2006 - 2010 a total of 1440 salt samples were collected, of which 1379 were qualified iodized salt, 34 unqualified, 27 non-iodized salt; iodized salt coverage rate, qualified iodized salt and iodized salt consumption rates were 98.13% (1413/1440), 97.59% (1379/1413) and 95.76% (1379/1440),respectively, and the rate of non-iodized salt was 1.88% (27/1440). Conclusions The intake rate of qualified iodized salt in Xinjian county have reached the standards of eliminating IDD. The quality of iodized salt should be improved in few counties. In the future, we should also increase the use of various forms advocacy of IDD prevention and treatment, and educate the masses to enhance self-protection awareness, so that they can consciously resist the salt smuggling, and refuse to buy non-iodized salt.

〔Abstract〕 Based on elaborating the problems existed in traditional programming course, taking Beijing University of Chinese Medi-cine as an example, the paper puts forward interest teaching method, carries out comprehensive teaching reform from preparing lessons, classes, after-school three aspects, points out the key problems in implementation.Practice shows that this mode could stimulate students′learning interest and initiative and achieve good results.

〔Abstract〕 Taking Beijing University of Chinese Medicine as an example , the paper analyzes problems existing in teaching computer basic courses .It proposes to combine the teaching concept of flipped classroom with the case -based teaching method , reform the teach-ing contents, methods, processes and modes of computer basic courses in medical colleges and cultivate students ′abilities to analyze and solve problems , and analyzes the feasibility .

Objective To explore the effect of different method in preventing broncho-pulmonary dysplasia(BPD) in very low birth weight infants(VLBWI) during mechanical ventilation.Methods The gestational age of 71 infants with VLBWI was (30?2) weeks and the average weight was (1235.2?160.6)g.The infants were randomly divided into three groups,they received different therapeutic regimens during mechanical ventilation:32 cases were treated with permissive hypercapnia(PHC) ventilation in group Ⅰ;20 cases were treated by intratracheal instillation of pulmonary surfactant(PS) in group Ⅱ;19 cases were treated by inhalation of becotide(beclomethasone dipropionate,BDP) in group Ⅲ.The ventilator settings,blood gas analysis,clinical symptoms and therapeutic effect were statistically analyzed and compared.Results The peak inspiratory pressure(PIP) and ventilation rate(VR) of ventilator parameter were (18.3?1.6)cmH_2O and (35?5)bpm in group Ⅰ,there was significantly lower than that in group Ⅱ and group Ⅲ(P0.05).The incidence of BPD was 16%(5/32) in group Ⅰ,5%(1/20) in group Ⅱ and 5%(1/19) in group Ⅲ;The mortality rate of PHC group(group Ⅰ) was 6%(2/32) and 5%(1/20) in group Ⅱ.Conclusion The application of permissive hypercapnia,intracheal instillation of pumlonary surfactant and inhalation of becotide all can prevent effectively the occurrence of severe broncho-pulmonary dysplasia in VLBWI during mechanical ventilation.

Objective To evaluate the efficacy of port catheter system(PCS)placement in pulmonary artery via percutaneous subclavicle vein treatment for multiple metastatic tumor in the two lungs and discuss the PCS technique.Methods Fifteen multiple metastatic tumor patients(13 hepatocellular carcinomas,one mandible grand adenocarcinoma,one oral bottom squamous carcinoma)were carried out with pulmonary artery PCS placement by way of percutaneous subclavicle vein.FPA/FPM/GP chemotherapy scheme were introduced every 4～6 weeks.Results The success rate of PCS placement technique was 93.3%(14/15).One case failed.Percutaneous subclavicle veins were performed 14 cases in right side and 1 in left one.Following up 2～43 months,2～7 chemotherapy cycles(mean 5 cycles)were accomplished,and the clinical CR and PR were achieved in 1 and 3 cases respectively with clinical efficacy rate 28.6%(4/14).Major side reaction was late wound healing in 1 case.Conclusion PCS placement in pulmonary artery treatment for multiple metastatic tumor in the two lungs is effective,and mastering operation technique is the key for increasing operation suc- cess rate.
