Objective To research patients with ophthalmologic perioperative information systems, strengthening the information management of nursing work, achieving consensus and sharing of health care information resources, and then to explore the clinical application effects of this ophthalmologic peri- opera-tive information systems. Methods The convenient sampling method was used in the study. The control group was consisted of 1 740 patients in our hospital from January to March 2013 (before the application of ophthalmologic perioperative information systems). The observation group included 2 078 patients of the same hospital (after the application of ophthalmologic perioperative information systems). The control group adopted routine pre- operative information acquisition method, the observation group applied ophthalmologic perioperative information systems, which included input function, reading function and statistical function. The incidence rate of canceled operation and satisfaction were compared between two groups. Results Ophthalmologic peri- operative information systems provided patients with information gathering, query and analysis in different periods. The rate of the canceled operation reduced in the observation group from 3.74% (65/1 740) to 2.69% (56/2 078) in the control group, χ2=3.91, P<0.05. The satisfaction degree increased from 91.84 % (1 598/1 740) in the observation group to 96.78% (2 011/2 078) in the control group, χ2=44.60, P<0.05, the difference was statistically different. The hospitalization days from April to September in 2013 shortened compared with those of the same period in 2012. Conclusions Ophthalmologic peri- operative information systems promotes the scientific and informatization of nursing information, which is worthy of wide clinic application.

Objective To investigate the value of bone turnover markers(BTMs) in forecasting the variance of bone mineral density (BMD) by studying the relationships between BTMs and BMD in persons aged 80 and above.Methods A sample of 1 509 subjects aged 80 and above was recruited.All subjects underwent BMD measurement by dual energy X-ray absorptiometry,and BTMs (C-telopeptide of type 1 collagen,N-terminal propeptide of type 1 procolagen,osteocalcin) measurements.The relationships among all the BTMs,and between BMD and BTMs were analysed.Results In subjects aged 80 and above,the relationships among BTMs were moderately positive(all P＜0.05).In men aged 80 and above,BMDs were inversely associated with BTMs(all P＜0.05),and in women,BMDs were inversely associated with osteocalcin (P＜ 0.05).Conclusions The clinical significance of BTMs in persons aged 80 and above indicates bone resorption when BTMs are raised.In men aged 80 and above any of BTMs may be selected to evaluate bone metabolism ; while in women,osteocalcin should be selected.

Objective To study the influences of ginsenoside Re on learning and memory abilities of natural apolexis rats and to probe its preliminary mechanism.Method Water maze test for old rats was used to observe the effect of ginsenoside Re on learning and memory,and electrophysiological technique to record the long-term potentiation(LTP)in basic synaptic transmission of the dentate gyrus in anesthetized rats.Results Ginsenoside Re can markedly counteract memory acquisition impairment in natural apolexis rats,and enhance the synaptic transmission in the dentate gyrus and form the LTP consequence.Conclusion Ginsenoside Re can improve the learning and memory obstacle in rats,the mechanism may correlate with its enhancing the basic synaptic transmission and promoting the magnitude of LTP of the dentate gyrus.

Objective To investigate the effects of aquaporin 3 (AQP3) and phospholipase D2 (PLD2) on the proliferation and apoptosis of a human cutaneous squamous cell carcinoma cell line A431.Methods Three small interfering RNAs (siRNAs) were constructed targeting the AQP3 and PLD2 genes separately,and transfected into A431 cells using liposomes.Then,fluorescence quantitative PCR was performed to find the most efficient siRNAs.Western blot was conducted to detect the protein expression levels of AQP3 and PLD2 in A431 cells after transfection with the selected AQP3-siRNA and PLD2-siRNA.Some A431 cells were divided into five groups:normal control group without any treatment,transfection reagent group treated with the oligofectamine reagent only,negative control group transfected with the negative control siRNA,AQP3-siRNA group transfected with the selected AQP3-siRNA,PLD2-siRNA group transfected with the selected PLD2-siRNA.After additional culture,cell counting kit-8 assay was performed to evaluate the proliferation of A431 cells,flow cytometry to detect the apoptosis of A431 cells after annexin V-fluorescein isocyanate/propidium iodide double-staining.Statistical analysis was carried out by the paired t test.Results The transfection with AQP3-siRNA and PLD2-siRNA induced a significant decrease in the mRNA and protein expressions of AQP3 and PLD2 respectively in A431 cells when compared with the untransfected cells.Compared with the negative control group,the proliferation of A431 cells was significantly decelerated at 24,48 and 72 hours after transfection in the AQP3-siRNA group (t =24.10,11.00,9.54,respectively,all P ＜ 0.01) and PLD2-siRNA group (t =30.47,7.02,8.73,respectively,all P ＜ 0.01).A significant increase was observed in the apoptosis of A431 cells at 48 and 72 hours after transfection with AQP3-siRNA (t =11.36,20.91,respectively,both P ＜ 0.01),and at 72 hours after transfection with PLD2-siRNA (t =4.86,P ＜ 0.05) compared with the negative control group.Conclusion The down-regulation of AQP3 and PLD2 expressions by siRNA can inhibit the proliferation,but induce the apoptosis,of A431 cells.

Background and purpose: Docetaxel plus prednisone chemotherapy can improve the patients' survival for castrate-resistant prostate cancer. Angiogenesis inhibitors can also inhibit the growth of tumor. The curative effect of combined treatment is still not clear. This study aimed to evaluate the efficacy of docetaxel plus prednisone combined with thalidomide in treating castrate-resistant prostate cancer (CRPC) patients with bone metastasis. Methods:A total number of 78 CRPC patients were selected in Fuzhou General Hospital from Dec. 2008 to Jun. 2015. Seventy-eight patients were divided into two groups: 40 patients in chemotherapy group (docetaxel plus prednisone) and 38 patients in combined treatment group (docetaxel plus prednisone combined with thalidomide). A total number of 78 subjects were evaluated by the effective rate, the remission rate of bone pain, the prostate specific antigen (PSA) progression-free surviv-al, the overall survival and adverse effect. Results: The response rate (65.79%) and the remission rate of bone pain (86.84%) in combined treatment group were both higher than those in chemotherapy group (40.00% and 60.00%, P<0.05). The PSA progression-free survival (4.13 months), progression-free survival (4.25 months) and the overall survival (18.06 months) in combined treatment group were all longer than those in chemotherapy group (3.54, 3.75 and 16.26 months). The PSA pro-gression-free survival was significantly longer in combined treatment group (P<0.05). There was no significant difference in the overall survival between two groups (P>0.05). The rates of adverse effects including peripheral neuritis and lethargy in combined treatment group (26.32% and 55.26%) were higher than those in chemotherapy group (5.00% and 17.50%, P<0.05). Conclusion: Thalidomide combined with docetaxel plus prednisone in CRPC patients with bone metastasis can prolong the PSA progression-free survival and overall survival. The adverse effects are mild. It may become a new choice of treatment for CRPC.

Objective To summarise the imaging features of rare mastitis and explore the diagnostic value of ultrasound, mammography and MRI for rare mastitis. Methods The record of 24 patients diagnosed as rare mastitis in our hospital from Jan. 2000 to Jun. 2009 was reviewed, including clinical manifestations, pathological results, imaging diagnosis and diagnostic accurate rate. Results Of the 24 patients, 14 patients were ductal ectasia with chronic mastitis, 3 granulomatous mastitis, 6 chronic abscess and 1 mammary tuberculosis. 13 patients underwent ultrasonic scan, 12 patients underwent mammography and 3 patients underwent MRI, with the diagnostic accurate rate 77%, 25% and 100% respectively. Conclusions There are no special imaging manifestations for most rare mastitis, however, some differential characteristics still exist. MRI has a higher accuracy compared to ultrasound and mammography. The combination of multiple imaging methods can improve diagnostic accuracy.
