The problem that the medical information work is specific expression of hospital comprehensive efficiency is pointed out. By giving medical information personnel is the key of the information construction, the emphasizing important effect of it and aiming directly at "patient-centered" to produce the construction level on the function of information center and medical information personnel. The hospital development combines with reality of medical information to prefer culti- vation suggestion of the medical information personnel.

To investigate the methods of learning coaxial microincision phacoemulsification and assess the related complications.METHODS:The clinical data of 1 080 eyes of coaxial microincision phacoemulsification performed by beginners from October 2011 to December 2013 was retrospectively analyzed. ln order of surgery dates, the patients were equally divided into groups A, B, C and D, 270 eyes in each group. Comparisons were made among the four groups in operation time, cumulative dissipated energy (CDE), rate of intraoperative, and postoperative complications at 1d; and best corrected distance visual acuity (BCDVA) at 1mo postoperatively.RESULTS:No significant differences were found in age, sex, lens grading, BCDVA at 1mo postoperatively among the four groups ( P> 0. 05 ). The operation time was significantly longer in group A than in groups B, C and D (25. 15 ± 3. 11min vs 15. 20 ± 3. 40min, 14. 71 ± 3. 02min and 14. 41±2. 91min, P<0. 05). No significant differences were found in the operation time among the other three groups (P>0. 05). The CDE of grade ‖ and Ⅲ was significantly higher in group A than that in groups B, C and D (95. 9%, 97. 8% and 98. 5%) (P<0. 01). The number of continuous curvilinear capsulorhexis ( CCC ) were performed successfully was significantly less in group A ( 80. 7%) than the other three groups (95. 9%, 97. 8% and 98. 5%) (P<0. 01). The incidence of posterior capasular rupture of group A (7. 8%) was higher than that of group B (3. 7%), group C (1. 1%) and group D (0. 4%) (P<0. 05), but there was no significant difference between group C and group D (P>0. 05). There were no significant differences both in the number of corneal edema and BCDVA at 1d between group A and group B. (P=0. 66, P=0. 53).CONCLUSlON: With learning step by step, appropriate training program, careful case selection, and accurate managing complications, coxial microincision phacoemusification can be safe for a beginner.

One hundred and six patients with hip fracture admitted in hospital from 2011 to 2014 were randomly divided into two groups: 52 patients received celecoxib and parecoxib ( trial group ) and 54 patients received oxycodone hydrochloride and bucinnazine (control group).On d1 and d7 after the surgery, serum levels of C-reactive protein[(26.2 ±5.4) and (10.4 ±2.8) mg/L], tumor necrosis factor-α[(40.6 ±6.1) and (31.8 ±5.3)ng/L], interleukin-6 [(22.3 ±5.7) and (18.3 ±5.2) ng/L] and prostaglandin E2 [(181.1 ± 19.4) and (153.3 ±25.8) ng/L] in trial group were all significantly lower than those in control group [(46.1 ± 14.0) and (22.1 ±5.2)mg/L, (53.2 ±5.3) and (44.6 ±7.4) ng/L, (43.3 ±11.0) and (29.1 ±8.6)ng/L, (354.3 ±105.9) and (251.0 ±37.3)ng/L, all P<005].The length of hospital stay [(11.0 ±2.2) d], rate of lung infections (6/52) and neurological abnormality (3/52) in trial group were significantly lower than those in control group [(15.5 ±1.8) d, 15/54 and 11/54, all P <0.05].The expression of CD4 +CD45 + T cells [(34.9 ±3.7)% vs.(42.5 ±4.3)%] was reduced and CD4 +Foxp3 +T cells [(19.7 ±3.8)% vs.(6.9 ± 1.5)%] was increased at 24 h after surgery in trial group compared with control group( all P<0.05).The results indicates that calecoxib can reduce the inflammatory reaction by promoting CD4 + to Foxp3 + CD4+T cell differentiation and may improve the prognosis of elderly patients with hip fracture.

A UPLC method has been developed in the current investigation for simultaneous determination of nine chemical markers of Bletilla striata, 4-hydroxymethylphenyl beta-D-glucoside, blestroside, dactylorhin A, militarine, dihydrophenanthrene 5, gymnoside V, dihydrophenanthrene 1, benzylphenanthrene 3 and gymnosides IX. Separation was performed at 45 degrees C on an ACQUITY UPLC BEH C18 column (2.1 mm x 150 mm, 1.7 microm) with a gradient solvent system of acetonitrile-water as the mobile phase. The flow rate was 0.3 mL x min(-1), the detection wavelength was 280 nm. The results showed that the nine chemical markers could be well resolved and that in the selected linear range, all calibration curves of the nine chemical markers showed good linearity (r > or = 0.999 3). The recoveries (n = 6) were in the range of 98.15% - 102.2% and RSDs were between 2.1% - 3.6%. The data suggested that the developed UPLC-UV method had good reproducibility, robustness, and accuracy, which was suitable for the quality control of Bletilla striata. Applications of the method showed that the nine chemical markers had higher contents in the wild B. striata than in the cultivated ones.
