Objective To investigate the level of disaster nursing ability and cognitive status of nursing manager,explore the characteristics and influencing factors,in order to provide a basis for intervention in improving the capacity of disaster nursing care.Methods 113 nursing managers were recruited by convenience sampling from a first-class ternary hospitals in Anhui province.They were investigated by a self-designed demographic data questionnair and disaster nursing and cognitive scale.Results The score of the disaster nursing ability of the nursing managers was 114.12±18.21,the mean score was 2.65±0.42,both below the medium level.Regression analysis showed that the nursing age of nurse manager,whether accepted disaster nursing training after work were the influencing factors of the disaster nursing ability of the nursing managers and explained 33.5％ of the variance.Conclusions The capacity of disaster nursing care of nurse managers is not high.The nursing age of nurse manager,whether accepted disaster nursing training after work were the influencing factors of the disaster nursing ability of the nursing managers.

Objective To detect nuclear DNA degradation of bone marrows and brains in rat cadavers at different temperatures,and develop a new parameter for estimating early postmortem interval(PMI).Methods The brain and bone marrow were taken out for every 4h,during 0~40h after death at 10℃ and 20℃,respectively.And the single cell gel electrophoresis(SCGE) was carried out to detect the nuclear DNA degradation.Linear regression analysis was used to assay the relationship of the comet parameter HeadDNA%,Tail Length(TL) and Olive TailMoment(TM) with PMI.Results Different decline degrees of comet HeadDNA% were found in both brain cells and bone marrow cells after death,the decline of HeadDNA% in brain cells at 20℃ was faster.Compared with degradation in marrow cells,the linear relation between degradation of brain cells and PMI was better.Conclusion with that of comet parameters TL and TM,the perfect linear relationship between HeadDNA% and PMI was also observed.Conclusion Brain tissues are more suitable for PMI estimation by detecting degradation of DNA with SCGE.The HeadDNA% is more valuable for PMI estimation than TL and TM.

Objective To investigate the clinical effects of open decompression drainage on acute pulpitis.Methods Totally 180 acute pulpitis patients hospitalized during January 2012 to September 2014 in our department were selected and randomly divided into control group and observation group (n=80 each).The control group was treated with pulp inactivating agent and the observation group was given open decompression drainage.The clinical effects,analgesia efficiencies at 7d after treatment,treatment course and the complications were compared between the 2 groups.Results There was significant difference in the effective rate between control and observation groups after treatment [61.3％ (49/80 cases) vs.86.3％ (69/80 cases),P＜0.05].The analgesia efficiencies at 7d after treatment was 46.3％ (37/80 cases) in control group and 73.8％ (59/80 cases)in observation group (P＜0.05).There was no significant difference in treatment course between two groups [(7.7±1.4) times vvs.(6.1± 1.2) times,P＞0.05]].6 patients developed periapical periodontitis in control group,and only 4 cases in the observation group (P＞0.05).Conclusions Early open decompression drainage has good clinical effects and analgesia efficiencies in treatment of acute pulpitis,which is worthy of clinical application.

Objective To explore the feasibility and application value of combined C2 laminar screw fixation technique in treatment of cervical vertebral injury. Methods Dense axial CT scanning was done on C2 laminar of 32 specimens of cervical vertebra to measure the length and height of the axis, the thickness of upper, middle and lower parts of the axis as well as the angle between the axial ray and the sagittal plane. There were eight patients with cervical vertebral injury including two with type Ⅱ odon-told process fractures combined with backward dislocation of atlanto-axial joint, one with forward disloca-tion of atlanto-axial joint, one with nonunion of odontoid process fractures, two with type Ⅲ odontoid process fractures combined with atlanto-axial joint instability and transverse ligament rupture, one with type Ⅱ Hangman fracture combined with instability of C2～3 and one with forward dislocation of atlanto-axial joint combined with transverse ligament rupture. With accomplishment of traction reduction, combined fixation with axis laminar screws and posterior autogenous lilac graft fusion were done based on injury se-verity of the patients. Results The length and height of axis laminar was (26.2±1.2) mm and (12.8±1.6) mm, respectively. The thickness of upper, middle and lower parts of the C2 laminar was (3.0±1.4) mm, (6.0±1.6) mm and (5.6±1.2) mm, respectively. The mean angle between the axial ray and sagittal plane was 43.5°. All patients were followed up for 6-14 months ( mean 6 months), which showed that all patients obtained favourable bone union and all screws remained at sound position, without deflexion of the screws or any perioperative or postoperative complications. No screw loosening or breakage occurred. Conclusions C2 laminar screw fixation technique can prevent the risk of vertebral artery injury during screw insertion. In the meantime, such technique is simple to operate and free from limitation of the vertebral artery in the cervical foramen. Whole course of visualization during C2 laminar screw insertion may facilitate it as a supplementary method for conventional posterior C2 screw fixation.

Objective To study the clinical application of dynamic monitoring of mainstream endtidal carbon dioxide in neonatal respiratory distress syndrome.Methods All of 23 premature neonates diagnosed with NRDS and placed on mechanical ventilation were admitted in this study.Their PetCO_2 was continuously monitored and paired with PaCO_2 at 112 different time points.The correlation between PetCO_2and PaCO_2 was compared.Results This study showed that the average PaCO_2 measured for 112 times was(38.2±5.6)mm Hg(1 mm Hg=0.133kPa)and the corresponding PetCO_2 was,(32.4±4.9)mm Hg;it also showed that PetCO_2 was positively correlated with PaCO_2 and PetCO_2 was even more closely correlated with PaCO_2 in infants with second degree of NRDS than in patients with third and fourth degree of NRDS.Conclusions Dynamically monitoring mainstream PetCO_2 is applicable in mechanically ventilated premature infants with NRDS,it can accurately reflect the level of PaCO_2;Thereby reducing the blood gas analysis,thus reducing the suffering of nursing workload and children.But it has limited significance in cases of severe NRDS.
