Objective To understand and analyze the situation of orthopedic nursing manpower resources in grade- Ⅲ general hospital in Shanghai and provide empirical evidence for appropriate allocation and exploitation of nursing manpower resources. Methods Data were collected by questionnaire and then underwent analysis. Results In 2009,the number of authorized beds was 1866,the actual number of open beds was 2007.The number of nurses was 595 (2 male).The ratio of ward bed and nurse were 1:0.319 and 1:0.296, calculated by the authorized beds and authorized beds, respectively.The average age of head nurses was (37.53±6.11 ) years old, average working life span was (17.87 ± 6.16) years; college degree or above accounted for 95.56%; middle professional titles accounted for 62.22%. College degree or above accounted for 75.13% in nurses, junior professional titles accounted for 92.1%; age group is mostly concentrated in the 20 to 29 years of age, accounted for 67.06%; working life span concentrated within 10 years, accounted foi 73.11%. The education level mainly is primary school in the care workers (carer), accounted for 45.83%; concentrated in the 40 to 49 years of age, accounted for 60.42%; working life span concentrated in more than 6 years, accounted for 55.21%. Conclusions There are shortage of orthopedic nursing manpower resources, unreasonable allocated structure, lack of male nurses in grade- Ⅲ general hospital in Shanghai. The management of the care workers should be standardized.

We describe the case of a 79-year-old male presented with sudden onset of abdominal pain and mild breathlessness, and complicated acute progressive anemia with haemoglobin which declined from 120 g/L to 70 g/L within five days. An urgent computed tomography an-giography showed acute thoracic aortic dissection, DeBakey type IIIb, a dissecting aneurysm in the proximal descending thoracic aorta start-ing immediately after the origin of the left subclavian artery and extending distally below the renal arteries with evidence of rupture into the right pleural cavity for massive pleural effusion. Plasma D-dimer, brain natriuretic peptide and C reactive protein level were elevated. Our case showed that D-dimer can be used as a‘rule-out’ test in patients with suspected aortic dissection. A raised BNP may exert a protective role through anti-inflammatory endothelial actions in the systemic circulation.

Objective To investigate the endoscopic prevalence of erosive esophagitis (EE) among 13 hospitals in Guangdong province of China. Methods Retrospectively reviewed all the cases (63459 cases) that received oesophagogastrodeuodenoscopy in 13 main hospitals in Guangdong province of China in 2003. Los Angeles criteria for classification of erosive esophagitis were employed as the basis of analysis. Results One thousand two hundreds and sixty-three patients (age range 3-90yr, mean 50. 2 ?17. 1 ) were found to have EE. The overall prevalence of EE was 1. 99% (1263/63459). The prevalence of EE in A, B, C, and D grade were 0. 94% , 0. 69% , 0. 21% and 0. 14% respectively. Age correlated positively on endoscopic grading of EE (F=22. 932, P

Poly (hydroxyethyl methacrylate) (PHEMA) hydrogel for intraocular lens (IOL) materials was synthesized by solution polymerization using 2-hydroxyethyl methacrylate (HEMA) as raw material, ammonium persulfate and sodium pyrosulfite (KPS/SMBS) as catalyst, and trietyleneglycole dimethacrylate (TEGDMA) as cross-linking additive. Effects of reaction time, temperature, dosage of catalyst and cross-linking additive on mechanical strength and the equilibrium water content (EWC) of the PHEMA hydrogel were systematically investigated and their structure and optical property were also characterized. The experimental results showed that the optimum conditions for preparing PHEMA hydrogel are: catalyst 0.5 wt%, cross-linking additive 1.0 wt%, reaction temperature 40 degrees C, reaction time 36 h. Under the optimum conditions, the tensile strength of PHEMA hydrogel prepared is as high as 0.57 MPa, hardness of Shore A is 23.0, EWC is over 40%, and light transmittance is over 97%.
