Objective To explore the needs of intensive care unit (ICU) patients in the intensive care unit from nurses' perspectives.Methods A descriptive qualitative study of data generated from individual in-depth interviews of eleven intensive care nurses was to learn about the needs of ICU dying patients.Colaizzi analysis was used to analysis the data.Result The ICU nurses' description for needs of ICU dying patients are described as:have no physical burden of pain,to maintain dignity,to be understood and to fulfill their wishes,and family members are able to calmly accept the fact that the patient is about to leave.Conclusion According to the needs of ICU dying patients,medical staff should further concern about the humane care for ICU dying patients,and provide quality nursing care to help them live peacefully through the final stages of life.

To study the cultural characteristics of mycelia of Ganoderma gibbosum, a medicinal fungus used in China. The growth rate and biomass of G. gibbosum mycelia were measured under different temperature, lightning carbon and nitrogen sources conditions. It showed that the optimal growth temperature for mycelia was 25 degrees C. Darkness was beneficial for mycelium growth. The initial pH 5.5 was suitable. The sucrose was the best carbon source and yeast extract the best nitrogen source, the optimal carbon-nitrogen ratio 60:2. These conclusions will offer references for further artificial cultivation and liquid fermentation.

OBJECTIVE: To discuss the feasibility of endoscopic frontal sinus surgery in the nasal septum median path. METHOD: (1) Sixty adult cadaveric heads fixed with formalin were CT scanned,and were three dimensional reconstruction. (2) Thirty adult cadaveric heads were sawn along the sagittal line close to the side of the nasal septum, then the important anatomic marks were observed and measured. (3) Combined with CT and anatomical data, thirty adult cadaveric heads were operated in different degree, and the damage of nasal septum and fila olfactoria were detected in the same time. RESULT: (1) The roots of middle nasal concha were simulated in the endoscopic frontal sinus surgery. The operation time, operative procedures, markers foundation, endoscopic back of posterior border of frontal sinus foundation and attached to the symphysis with cribriform plate and the top of ethmoidal sinus were recorded. (2) The intersection point formed by the level of middle nasal concha and the vertical of middle nasal concha corresponded with the nasal septum was called the M point. The distance from the M point to the horizon of the nasal bone was (20.07 +/- 6.21) mm, the distance from the M point to the first fila olfactoria was (24.38 +/- 7.68) mm, the distance from the first fila olfactoria to the posterior edge of frontal sinus was (9.57 +/- 2.73) mm, the distance from the root of the middle nasal concha to posterior edge of frontal sinus was (5.38 +/- 1.23) mm, the anteroposterior diameter of frontal sinus fundus was (7.62 +/- 2.45) mm, the transverse diameter of frontal sinus fundus was (9.41 +/- 3.37) mm, the seesaw diameter of frontal sinus partition was (16.97 +/- 3.23) mm, the anteroposterior diameter of frontal sinus partition was (12.34 +/- 2.23) mm. (3) The operation time through the nasal septum path was 105 minutes which combined with CT and anatomical measurements. 0 degrees endoscopy could be used to observe the frontal part of the lateral, posterior and top wall, while nasal septum remove should be finished with 30 degree endoscopy. The bottom of frontal sinus can be exposed and removed with 0 degree endoscopy. 3 cases of cadaveric frontal sinus lateral wall can not be observed with 70 degree endoscopy. 30 cases of cadaveric frontal sinus,some of the top and the lateral wall, anterior and posterior wall could be observed with 70 degree endoscopy, nasal septum damage range was about 2.23 cm x 2.59 cm, and no fila olfactoria damage was found. CONCLUSION Endoscopic frontal sinus surgery in the nasal septum median path is a good way to find frontal sinus.

Objective: To analyze the clinical features and the pathogenetic law of traumatic optic neuropathy through epidemiologic study. Methods: 265 cases (275 eyes) with TON treated in Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University from April 1999 to August 2015 were retrospectively analyzed. Multiple Logistic regression analyses were used to evaluate potential prognostic factors on visual acuity. Results: TON occured mostly in young (194/265, 73.21%) man (235/265, 88.68%), the majority of patients came from villages and towns (209/265, 78.87%). Traffic accident (197/265, 74.34%) remained the main etiology, with strike (36/265, 13.58%) and fall (17/265, 6.42%) as the common etiology. Most patients had head injuries. The effective rate of vision improvement was 53.45%(147/275). Multiple logistic regression analyses identified that initial visual acuity with light perception or better vision, optic canal fracture and orbital wall fracture were visual acuity key factors of TON (χ² value was 24.674, 19.755, 9.175, respectively, all P<0.01), initial visual acuity with light perception or better vision was the protective factor on visual acuity recovery (OR=5.008, P<0.001), the presence of optic canal fracture and orbital wall fracture were the risk factors on visual acuity recovery (OR value was 0.110, 0.329, respectively, all P<0.01). Conclusions Ton occurs mostly in young man because of traffic accident. Visual impairment of TON is severe. The suitable preventive measures should be carried out according to its epidemiological features.
