AIM: To evaluate the changes of corneal high - order aberration (including Coma, Spab, RMSh) after laser in situ keratomileusis (LASIK) with femtosecond laser, sub- Bowman keratomileusis ( SBK ) and laser epithelial keratomileusis (LASEK). METHODS: Of 82 myopic patients ( 164 eyes ), 31 patients (62 eyes) were treated by FS-LASIK, 31 patients (62 eyes) were treated by SBK, 20 patients (40 eyes) were treated by LASEK. Sirius system was used for measuring the coma aberration, spherical aberration, and high order aberration at 1, 15d,1, 3mo after surgery. RESULTS: 1) Vision: The uncorrected visual acuity of the three groups had no differences (P>0. 05). 2) Corneal aberrations: Three kinds of surgical procedure for patients with corneal aberration had significant impact. The C7, C8, C12 and RMSh of three groups were increased significantly (P<0. 05). The C7, C8, C12 and RMSh were not recovered to preoperative levels after 3mo. But the increase of patients after FS- LASIK was smaller than the other two groups, with statistical significance (P<0. 05). CONCLUSION: Compared with SBK and LASEK, FS - LASIK has better visual acuity in the early postoperative and corneal higher-order aberrations increase is relatively small.

Objective To study the clinical correlated factors of renal damage in henoch-schonlein purpura (HSP).Methods One hundred cases with HSP were retrospectively studied. Accoding to the urinary route examination, the patients were devided into 2 groups, HSP with (49 cases) and without renal damaged (51 cases). In addition, the group of HSP with renal damaged was further diveded into 2 groups, HSP with urinary abnormality passingly (27 cases) and persistently (22 cases). Clinical indicators were statistical analysed.Results To be compared with HSP without renal damaged, age,apread of the purpura, abdominal pain,hemorrhage of digestive tract were higher in HSP with renal damaged (P

ObjectiveTo study the levels of Tau protein and β amyloid protein(Aβ) in cerebrospinal fluid(CSF) in patients with mild cognitive impairment(MCI) and their significance of diagnosis. MethodsSensitive enzyme linked immunosorbent assay were performed to detect the CSF levels of Tau protein and Aβ in 32 patients with MCI and 15 healthy controls. ResultsSignificant elevation of the level of Tau protein and decrease of the level of the Aβ were observed in patients with MCI compared with healthy controls.ConclusionThe assays of the CSF Tau and Aβprotein levels can provide valuable biological marker for the diagnoses and treatment of MCI.

Objective To study the micro-pore architecture and mechanical properties of porous titanium scaffolds with diamond molecule structure produced by 3D print technology, so as to guide the development of 3D-prinited porous titanium orthopedic implants. Methods Selective laser melting (SLM) and electron beam melting (EBM) were used to fabricate porous Ti6Al4V scaffolds with diamond molecule structure. The micro-pore architectures of those scaffolds were observed using optical microscope and scanning electron microscope (SEM), and universal material testing machine was used to conduct compressive test on the scaffolds. Results Both SLM and EBM techniques had machining error and half-melted metal particles were found on the strut surface. The relative error of strut size produced by SLM and EMB was 20.9%-35.8% and －9.1%-46.8%, respectively. The scaffold with strut width of 0.2 mm could not be produced by EBM. The compressive strength and elastic modulus of the scaffold fabricated by SLM was 99.7-192.6 MPa and 2.43-4.23 GPa, respectively. The compressive strength and elastic modulus of the scaffold fabricated by SLM was 39.5-96.9 MPa and 1.44-2.83 GPa, respectively. Conclusions The manufacturing precision of SLM is higher than that of EBM. Porosity is the main factor that affects the compressive strength and elastic modulus of the scaffolds. In the same process, with the increase of porosity, both the compressive strength and elastic modulus decrease. When the porosities are similar, the scaffolds fabricated by SLM possess higher compressive strength and elastic modulus than those by SLM.

[Abst ract] Objective To explore the relationship between expression of S100B in hippocampus of depression model rats induced by chronic stress and its depression like behavior,and the antidepressant effect of fluoxetine.Methods 40 rats were put into control group,fluoxetine group,CUS group and CUS plus fluoxetine group,using random number table.Rats in each groups received corresponding treatment.Chronic unpredictable stresses (CUS) were performed on rats for 42 days.Fluoxetine (5 mg/(kg · d)) were delivered to rats by intragastric administration from day 22 to day 42.Then,S100B protein were marked and observed by immunohistochemical method.Open-field test,sucrose consumption and body weight were used to evaluate behavioral changes.Results Scores in behavioral test were reduced significantly by 42 days of stress (main effects of stress,P＜0.05).Effects of stress on behavioral scores were reversed by 21 days fluoxetine treatment (interactions,P＜0.05).CUS resulted in elevated expression of S100B in CA1,CA3 and DG sub-regions in experimental rats (OD values,CUS,0.331 ±0.01,0.353 ± 0.01,0.381 ± 0.007 ; control,0.238 ± 0.007,0.237 ± 0.010,0.228 ± 0.006.Simple effects of stress,P=0.000; P=0.000; P=0.000).Fluoxetine treatment reversed the elevated expression of S100B in CA1,CA3 and DG sub-regions in model rats (OD values:CUS plus fluoxetine,0.233 ± 0.015,0.240 ± 0.005,0.254± 0.015; fluoxetine,0.241±0.007,0.233±0.013,0.227±0.017; Interactions between fluoxetine and CUS,P=0.000; P=0.000; P=0.000).Conclusion Sub-regional over expression of S 100B in hippocampus is associated with depression like behavior of rats.Reversed S100B expression in these sub-regions is an indicator of effective antidepressant treatment but not a mechanism for it.

Objective:To study the association of air pollution with health service demand of the elderly and middle-age patients with cardiovascular and cerebrovascular diseases,and to provide a scientific ba-sis for development of environmental protection policy and health service policy of the Chinese govern-ment.Methods:This study included survey data on self-evaluated health,outpatient service demand and inpatient service demand of the patients with hypertension,heart disease and stroke in 62 cities of 1 7 provinces from China Health and Retirement Longitudinal Study(CHARLS)in 201 1 and 201 3,and com-bined it with the data on the annual concentrations of inhalable particulate matter(PM1 0 ),sulfur dioxide (SO2 )and nitrogen dioxide(NO2 )of those provinces and cities.Conditional Logistic regression was car-ried out to assess the possible effects of air pollutants on self-evaluated health and health service utiliza-tion.Results:The results showed that turning points existed in the effects of concentrations of NO2 and SO2 on the health service demand of the patients with hypertension,heart disease and stroke.The inpa-tient service demand of the hypertension patients increased with NO2 concentration when it was lower than 35.1 μg/m3 and decreased with NO2 concentration for higher value.Self-evaluated health of the patients with heart disease and stroke decreased with SO2 concentration when it was lower than 63.8 μg/m3 and increased with SO2 concentration for higher value.In addition,no evidence was found for the association between PM1 0 and health service demand.Conclusion:Air pollution may have effects on health service demand of the patients with hypertension,cardiovascular and cerebrovascular diseases,and different air pollutants at high or low concentration may have different health effects.

Objective:To explore the effect of humanistic care in patients with hematopoietic stem cell transplantation.Methods:Totally 51 patients with hematopoietic stem cell transplantation were recruited from the First Affiliated Hospital of Xi'an Jiaotong University,between September 2014 and July 2016,and were randomly divided into two groups.Patients in the intervention group (n =25) received humanistic care,while those in the control group (n =26) received routine nursing.The incidence of adverse psychological status and nursing satisfaction were compared between the two groups.Results:The incidence rate of adverse psychological state in the intervention group (16％) was significantly lower than that in the control group (53％),while the nursing satisfaction in the interventiongroup (92％) was significantly higher than that in the control group (69％),P ＜0.05.Conclusion:Application of humanistic care in the patients with hematopoietic stem cell transplantation can significantly improve nursing satisfaction and reduce the incidence of adverse psychological state,which will improve the confidence of the patients and the quality of nursing satisfaction.Consequently,it will promote the relationship between the nurses and patients.
