Hospital modernization is closely related to hospital information systems.The paper presents the notion of information flow and argues that the quality,speed,coverage,and efficiency of information flow in a hospital are the basic elements of its development.Hospital information systems provide systematic,primary and service support for various activities in the hospital and bring about changes in the essence of hospital culture.In their efforts to strengthen their information infrastructure,modernized hospitals should observe the principles of people first,cost-effectiveness balance and sustainable development and lay equal stress on cultivating specialized information personnel and improving the level of the entire staff in manipulating information and science and technology.

Objective To observe the clinical effects of ximingting plan in treatment of osteoporesis result in hypofunction of ovary.Methods Sixty women with osteoporesis result in hypofunefion of ovary were divided into two groups by random digits table with 30 cases each.The investigated group received ximingting pian,the controlled group received hormone replacement therapy(HRT).The changes of bone density,bone gla protein(BGP),estradiol,follicle-stimulating hormone(FSH),the thickness of endometrium,blood routine,urine routine,liver function and kidney function before and after 6 months treatment were measured.Results Bone density and BGP after treatment wag higher than that before treatment in two (6.78±3.97)g/L;in controlled group:(0.617±0.065)g/cm2 vs.(0.552±0.073)g/cm2 and(8.92 4±4.43)g/L vs.(6.83±4.29)g/L](P<0.05).The levels of estradiol and FSH had no marked changes in investigated group(P>0.05);but not this in controlled group(P<0.01).The total effective rate of curative effect and presenting symptom was 93.3%(28/30),93.3%(28/30)in investigated group and 90.0%(27/30),86.7%(26/30)in controlled group,there was no significant difference between two groups(P>0.05).There was no significant difference in blood routine,urine routine,liver function and kidney function before and after treatment in two groups(P>0.05).Conclusion Ximingting pian is efficacious and safe in the treatment of osteoporosis result in hypofunction of ovary.

[Objective]To investigate the expression and the mechanism of EGb after the spinal cord injury in SD rats.[Method]Spinal cord injury of the SD male rats was induced with Allen's way by a 5g?5 cm impact on the posterior T9 spinal cord in moderate degree. Rats were randomly divided into two groups. One group of rats were treated with normal saline solution, while another group were administrated EGb 0.75 ml/(kg?d). Rats were sacrificed at 1、3、5、7、14 d after the injury. The expression of iNOS was determined by immunohistochemistry.[Result]Positive expression of iNOS appeared in both groups and reached their peak on the 5th day after the injury. The expression of the EGb treated group were significantly lower than that of the control group (P

Objective To evaluate relations between lung cancer and the expressions of P53 protein together with proliferating cell nuclear antigen(PCNA) in specimens of lung lesions by needle biopsy.Methods CT-guidance percutaneous biopsy of lung lesions were performed in 66 patients with the determination of expressions of p53 protein and PCNA by flow cytometer (FCM). Results 1. The sensitivity of CT-guidance percutaneous biopsy was 94.3% in 53 cases of lung cancer with the diagnostic accuracy of 90.9% totally. The complication rate of pneumothorax was 4.6%. 2. The expression of P53 protein was (29.9?2.7)% in lung cancer (53 cases), while ( 17.9 ?2.8)% in benign lesions (13 cases) (t=2.0, P0.05).Conclusions FCM plays and valuable role in determining the expression of P53 protein and PCNA in the specimen of lung cancer by CT-guided percutaneous biopsy. The expression of p53 and PCNA may be useful in the diagnosis of lung cancer by providing the relation between imaging of lung cancer and the molecular mechanism, and furthermore revealing the characteristics of molecular biology of lung cancer at protein level.

We investigated whether platelet-activating factor (PAF) mediates endotoxin-induced changes of lipoperoxidation, lysosomal enzyme release and increased extravascular lung water content in dogs using a specific PAF receptor antagonist, SRI 63-441. Endotoxin infusion caused an increase in serum malonyldialdehyde (MDA) from baseline (100%) to 130.04?14.00% and 169.16?32.49% and ?-glucuronidase (?-g) activity to 191.05?86.71% and 242.54?49.09% at 3 and 6h, respectively. The bronchoalveolar lavage fluid (BALF) ?-g activity, lung MDA and extravascular lung water also significantly increased (P

Bi-polar,bi-pedicled separation delayed flaps were designed on the backs of New Zealand rabbits with the application of a medical silicon membrane as the separation material. Values of glucose and lactic acid, PtcO 2 were measured separately at proximal,middle and distal areas of the flaps after the distal pedice was cut at 0,1,4,7,14,21 days,respectively, after the formation of flaps. After flap delaying,PtcO 2 in separated flap was always lower than that of the mormal control,accompanied with glucose decrease and lactic acid increase, although there were significant differences in different areas of the flap. The survived area of the flap increased after 7 days. Furthermore,all the length of the flap survived after 21 days,although the level of glucose in the flap was still lower and lactic acid was still higher.The results suggested that by separation and delaying the flap may adapt gradually to hypoxia via lowered metabolism.For flap survival,the threshold value of glucose in flap is 0 01mmol/L , lactic acid is 0 47mmol/L,and PtcO 2 is 3mmHg .

Relation between change of capillary pressure, survival length in bi pedicled separation delay flap was observed. Bi polar, bi pedicled separation delay flaps were designed on the backs of New Zealand rabbits. Medical silicon membrane was used as separative material. Values of capillary pressure were measured at proximal, middle and distal points. Survival length increased with delayed time, capillary pressure at middle was lower in the bi pedicled separation delay flap. It is concluded that capillary pressure is increased greatly by separation delay, and there is a linear relation between capillary pressure and survival length of flaps.

Objective To study the effects of long-term injection of corticosterone (CORT) on the hippocampal astrocytes and synaptic plasticity in mice.Methods Male C57BL/6N mice (n=40) were randomly divided into control group and model group.Mice in the model group were treated with subcutaneous injection of CORT for 4 weeks to generate chronic stress depression model.Chronic stress model was proved to be established by tail suspension test and sucrose preference test and serum level of CORT was determined by radioimmunoassay.Protein expression levels of hippocampal synaptophysin (SYP) and postsynaptic density-95 (PSD-95) were detected by Western blot.Somal volume and protrusion length of glial fibrillary acidic protein-positive astrocytes were assayed by immunocytochemistry and quantitative stereological techniques.Results Immobility time in model group ((137.95±6.22) s) was significantly extended in comparison with that in the control group ((114.05 ± 4.12) s) (P＜ 0.01).Sucrose preference in the model group (62.42 ± 6.75)％ was lower than that in the control group (86.52±5.08)％ (P＜0.01).CORT levels in model group ((11.48±0.62) ng/ml) was significantly increased compared with that in the control group ((1.11±0.05) ng/ml) (P＜0.01).Hippocampal SYP (0.54±0.04) and PSD-95 (0.57±0.07) expression levels in model group were lower than those in the control group (0.99±0.14),(1.03±0.10) (P＜0.01).Somal volume in the model group ((132.04±9.23) μm3) and protrusion length ((1.39± 0.05) × 107 μm) was lower than that in the control group ((168.49±9.01)μm3),(1.77±0.10) × 107 μm) (P＜0.05,P＜0.01).SYP and PSD-95 expression level was found to be positively correlated with the reduction of the protrusion length(r=0.660,P＜0.01;r=0.614,P＜0.01)in astrocytes.Conclusion The results suggest that depression-like behavior-in-duced by long-term CORT treatment is possibly caused by the alternation of the synaptic plasticity associated with the reduction of the reducing the protrusion length.

AIM:To study the effect of chronic corticosterone ( CORT) injection on the depression-like behav-iors and the brain glycogen level in mice.METHODS:Male C57BL/6N mice (n=40) were randomly divided into nor-mal control group and model group.The mice in model group were subcutaneously consecutively injected with CORT for 4 weeks.The mouse model of chronic stress depression was constructed.The forced swim test and open field experiment were conducted to prove chronic stress model.The serum level of CORT in the mice was measured by radioimmunoassay.The protein levels of hippocampal synaptophysin ( SYP) and brain-derived neurotrophic factor ( BDNF) were detected by West-ern blot.Hippocampus glycogen, glycogen synthase and glycogen phosphorylase were determined by indirect fluorescence measurement.RESULTS:Compared with normal control group, the immobility time of the forced swim test in model group was significantly lengthened (P<0.01), and the ability of spontaneous activity was reduced (P<0.01), indicating that chronic CORT injection induced depression-like behaviors in mice.The CORT level increased significantly (P<0.01) in model group.CORT injection decreased the protein expression of hippocampal SYP and BDNF (P<0.01), reduced hipp-ocampal glycogen level (P<0.05) and glycogen synthase activity (P<0.05), and increased glycogen phosphorylase ac-tivity (P<0.05).CONCLUSION:Chronic CORT injection causes hippocampal neuron damage and induces the depres-sion-like behaviors of mice, which may be associated with decreasing hippocampal glycogen level by CORT.

ObjectiveTo analyze the mental status of the patients with irritable bowel syndrome (IBS).MethodsSixty IBS patients were evaluated with Self Rating Anxiety Scale (SAS), Self Rating Depression Scale (SDS), Symptions Check List-90 (SCL-90) and self-edited scale.ResultsThe primary causes of mental disorder of IBS patients were the stress events and lacking knowledge for IBS; the average SAS scores of sixty IBS patients were 52.32±10.19, SDS scores were 54.90±11.70; the average scores of SAS and SDS in the groups of midlife and young people were significantly higher than that in the group of agedness ( P<0.05). The total scores of SAS and SDS were not significantly difference among the patients with different culture level and sex ( P>0.05); except the scores of crankiness and opposition, the average SCL-90 scores of the sixty IBS patients were significantly higher than the normal ( P<0.05).ConclusionIBS relates to mental status and stress, proper mental intervention can ease the symptom and improve the quality of the living.
