ObjectiveTo investigate the early screening; treatment and care methods of the retinopathy (ROP) of preterm children. Methods210 premature children born in our hospital were selected to conduct eye screening,treatment and care from January to December 2009.The nursing key points were summarized. ResultsAmong 210 preterm children,15 cases occurred ROP,the rate was 7.1％.Lesions appeared to be the threshold for laser treatment in 8 patients(16 eyes),accounting for 3.8％.The ROP morbidity rate was higher in birth weight ≤ 1000 g group than that in birth weight ＞ 1000 g group,higher in gestational age ≤32-week group than that in gestational age＞ 32 weeks,higher in the inhalation oxygen concentration ≤ 96％ group than in inhalation oxygen concentration ＞ 96％ group.Significant difference existed in ROP and non-ROP preterm children. ConclusionsThe incidence of retinopathy of premature children was closely related with low gestational age,low birth weight and prolonged and high-concentration oxygen inhalation,timely screening and early intervention care should be given to them.

OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.

METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.

RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.

CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

AIM: To investigate whether the Acrysof Natural has the protective function for retina from blue light in morphology.METHODS: Fresh porcine eye cups were formed in vitro. Blue light beam between 420-450nm spectrum eradiated the porcine retina and cultured RPE cells in 30J/cm2 and 40J/cm2, respectively. The adjacent region in 3mm diameter was eradiated in various ways: exposed directly to light, through AcrySof one piece IOL, PMMA IOL,AcrySof Natural IOL, and without light. Then the eye cups were cultured for 48h. Lastly, tissue and cell structure were observed with light microscope and transmission electron microscope (TEM).RESULTS: In the retinal region without light, the structure of every layer was clear, cells in neuroepithelial layer arrayed in rule, some bubble presented in external granular layer and internal granular layer, RPE cells were compact, and the color of pigment article was coincident. In the region with direct blue light and that with 30J/cm2+Acrysof one-piece/ pMMlA, cells on photoreceptor and external granular layer were lost partially, bubble increased, RPE cells were with different sizes, and cell edema, cell lost and pigment article cluster could be seen.. In region with 30J/cm2+Natural, a little disorganization could be seen comparing to that without light, but more normal than those with Acrysof and direct eradia tion. When the power was 40J/cm2, the situation was similar to that with 30J/cm2 but more severe.CONCLUSION: ① the blue light intensity in 30J/cm2 and 40J/cm2 could both induce the acute retinal light injury, ② AcrySof one piece IOL and other PMMA IOLhave no obvious effect no retina comparing to direct eradiation, ③AcrySof Natural can weaken the injury of blue light to some extent.

Objective To investigate the safety and therapeutic effect of intra-carotid infusion with cold sa line in rats with acute focal cerebral ischemia-reperfusion injury.Methods 60 rats were randomly divided into six groups:sham operated group,normal infusion group,stroke group,local hypothermic group,local normothermic group,and systemic infusion group.Brain infarct volume and cerebral water content were analyzed 48 h after ischemia.Neurological deficits were assessed using the mNSS 24 h and 48 h after infarction.Results In the local hypothermic group,brain temperature was reduced to 33 to 34 ℃ within 5 to 10 minutes,and this significantly low temperature maintained to nearly 60 minutes after infusion continued.Physiological variables were not significantly different among each time point (P ＞ 0.05).No significant morphological abnormality was found in brain sections stained with TTC and HE.Animals receiving local cold infusion significantly decreased infarct volume and brain water content compared to stroke group (P ＜ 0.05).Both 24 h and 48 h mNSS in local hypothermic group was significantly lower than those in other groups (P ＜ 0.05).Conclusions Intra-carotid infusion with cold saline can quickly and effectively reduce brain temperature and is a relatively safe cooling method.Local hypothermia significantly reduced brain infarct volume,decreased brain water content and improved neurological functional outcomes after brain ischemia.

OBJECTIVE To assess the clinical characters,diagnosis and treatment of invasive pulmonary(aspergillosis) in hemopathy patients.METHODS The hospitalized patients with hemopathy from Jul 2004 to Jun 2005 was retrospectivly analyzed.RESULTS Among 155 hemopathy cases,3 cases developed invasive pulmonary(aspergillosis),from them 2 died and 1 cured.CONCLUSIONS Overimmnosuppression is one of the main risk factors for invasive pulmonary aspergillosis.Amphotericin B is still the best choice for the treatment of aspergillosis and its gradual,low concentration administration can ease the side effects.

Objective To determine alkylglycerol (AKG) contents and variation in breast-milk of lactating women. Methods Five cases of healthy lactating women with term delivery were selected from June 2011 to June 2012. Breast-milk samples were collected at 1, 2, 3, 4, 8, 12, 16, 20 and 24 weeks postpartum. Breast milk samples were extracted, saponificated and derivatized. AKGs composition in breast-milk was quantitatively analyzed by GC chromatography. Results Mean 16C:0 AKG content in breast-milk decreased from(17.31 ± 3.59)× 10-3g/L to(11.14 ± 1.83)× 10-3g/L. Mean 18C:0 AKG content de-creased from(14.95±6.00)×10-3g/L to(9.68±2.51)×10-3g/L. Mean 18C:1 AKG content fluctuated between(4.64±0.91)×10-3g/L and(3.95±0.68)×10-3g/L. Conclusions 16C:0, 18C:0 and 18C:1 AKG contents exist in Chinese breast-milk through determina-tion by GC chromatography, and the concentrations vary among different stages of lactation.
