OBJECTIVE:To probe into the status quo and tendency of the utilization of anticoagulant drugs in our hospital. METHODS:The utilization of anticoagulant drugs in our hospital from 2004 to 2007 were analyzed statistically with regard to drug varieties,consumption quantity and consumption sum as well as DDDs. RESULTS:The consumption sum of anticoagulant drugs in our hospital increased year by year. Of all the anticoagulant drugs,leading the list in terms of consumption sum were ozagrel,low molecular heparin calcium and clopidogrel. CONCLUSION:The utilization of anticoagulant drugs in our hospital is basically in line with the current medication principle of anticoagulant drugs and the general medication trend both at home and abroad.

Objective To investigate the effects of recombinant human connective tissue growth factor (rCTGF) on the expression of osteoprotegerin (OPG) and RANKL ( receptor activator of NF-κB ligand ) in human osteoblasts, as well as the mechanisms involved. Methods Human osteoblasts were treated with rCTGF. The expressions of OPG and RANKL were assessed by Western blotting. The expressions of focal adhesion kinase ( FAK), mitogen-activated protein kinase (MAPK) were also observed. Results rCTGF inhibited RANKL protein expression in a dose-and time-depentent manner in human osteoblasts, while the expression of OPG kept unchanged. rCTGF induced activation of p38MAPK and dephosphorylation of FAK in human osteoblasts, but had no effect on ERK and JNK phosphorylation. p38MAPK inhibitor SB23058 abrogated the inhibitory effect of rCTGF on RANKL in human osteoblasts. Conclusion rCTGF inhibits the expression of RANKL in human osteoblasts via activation of p38MAPK and dephosphorylation of FAK.

Human osteoblast was treated with recombinant human connective tissue growth factor (rCTGF). This experiment showed that rCTGF increased membrane type-1 matrix metalloproteinase and matrix metalloproteinase-2 protein expression in a dose- and time-depentent manner in human osteoblasts. rCTGF induced activation of p38 MAPK in human osteoblasts. p38 MAPK inhibitor SB23058 abrogated the effect of rCTGF on the expressions of membrane type-1 matrix metalloproteinase and matrix metalloproteinase-2 in human osteoblasts.

An HPLC-DAD-MS/MS method was developed for rapid analysis and identification of degradation products of buagafuran. Buagafuran and degradation products were separated on a Zorbax C8 column (5 microm, 4.6 mm x 150 mm) using acetonitrile-water (78 : 22) as mobile phase. The elutes were detected with diode array detector and tandem mass spectrometer via electrospray ionization source in positive ion mode. According to analysis of the retention time, UV spectra and MS, MS/MS data, combined with the possible degradation reaction of buagafuran, the structures of main degradation products were inferred. The results showed that six main degradation products were oxidation or peroxidation productions of buagafuran. Degradation product A was a double bond epoxidation product of buagafuran, degradation products B, C, D and E were the further oxidation products of degradation product A, degradation product F was a peroxidation product of buagafuran. The results indicated that the established method was effective in the rapid identification of the degradation products of buagafuran.

Objective To investigate the effects of recombinant human connective tissue growth factor (rCTGF) on the proliferation, differentiation and apoptosis in human osteoblasts. Methods Human osteoblasts were treated with rCTGF, cell proliferation was measured by [3 H] -thymidine ([3 H] -TdR) incorporation method,the activity of alkaline phosphatase (ALP) was determined using α-nitrophenyl phosphate as a substrate, the expression of type Ⅰ collagen was determined by Western blotting, osteocalcin in conditioned media was measured by radioimmune assay, and cell apoptosis was assayed by flow cytometry. Results rCTGF promoted proliferation and differentiation of human osteoblasts in a dose-depentent manner, rCTGF increased ALP activity, osteocalcin and type I collagen secretion in a dose-depentent manner, rCTGF inhibited human osteoblastic apoptosis induced by serum deprivation. Conclusion rCTGF can promote osteoblastic proliferation, and differentiation and protect osteoblast against apoptosis, suggesting that CTGF plays an essential role in bone metabolism.

Objective To study the influence of different time of lavipeditum with traditional Chinese medicine on recovery of gastrointestinal function right after cesarean section, to find the best lavipeditum time and improve the therapeutic effect of lavipeditum with traditional Chinese medicine. Methods 388 cases parturents after cesarean section were selected and were randomly divided into the observation group(200 cases)and the control group(188 cases)according to their bed number. The observation group began lavipeditum with Chinese medicine 6 hours after operation, and was scheduled 7:00-8:00 in the morning, 21:00-22:00 in the evening, lasted 20 minutes every time for consecutive 3 to 5 days. the control group started lavipeditum with Chinese medicine one day after operation, and continued lavipeditum any time they wanted. lasted 20 minutes every time for consecutive 3 to 5 days. Recovery of intestinal function were com-pared between the two groups. Results Postoperative recovery time of bowel sounds, anal exhaust time for the first time, the first defecation time, appetite and sleep quality three days after operation in the observation group were beuer compared with the control group. Conclusions Timing of lavipeditum with Chinese medicine is more effective for recovery of gastrointestinal function after cesarean section, it embodies the importance of time medicine and reach best aims.

Two hundred women with singleton pregnancy at full term undergoing cesarean section with combined spinal-epidural anesthesia were randomly assigned into 2 groups (n=100 in each group). During anesthesia the polyvinyl chloride epidural catheter was used in control group and the wire-reinforced epidural catheter was used in study group.The results showed that the number of patients in whom blood or blood-tinted fluid was withdrawn from epidural catheter was significantly lower in study group than that in control group.The domestic wire-reinforced epidural catheter can reduce the incidence of blood vessel injury induced by insertion of epidural catheter.

In order to improve the quality of teaching in medical genetics,we adopted a lot of measures in medical genetics teaching program according to the requirements of basic course and the characteristics of lower grade undergraduates.Firstly,cultivating students' awareness of genetic diseases; Secondly,integrating related courses and selecting teaching contents seriously; Thirdly,guiding the class by introducing cases of illness.The results showed that these methods can promote the understanding of medical genetics and improve the quality of study in lower grade undergraduates.

Objective To investigate the preventive effect of self-made water bag combined with massage with Sanyrene on post-stroke pressure sores? Method A total of 60 post-stroke patients lying in bed were randomly divided into the control group and the observation group,30 cases in each? The control group received routine preventive nursing and the observation group were managed with self-made water bag and massage with sanyrene to prevention pressure sores? The two groups were compared in terms of sensation of humid skin and incidence of pressure sores? Result The sensation of humid skin was significantly better and the incidence of pressures sores was significantly lower than those is the control group(all P < 0?05)? Conclusion The self-made bag with massage with Sandrine may be effective in preventing post-stroke pressure sores in bedridden patients and is worthy of clinical application?

Objective To explore the effect of nursing procedure on pressure sore in patients with brain tumor.Methods The nursing procedures were used in the nursing of 86 brain tumor patients.The procedures included assessment of pressure ulcer risk factors and regulations of nursing objective and the measures for preventing pressure ulcer.Result None of the patients contracted pressure ulcer during operation.Conclusion The nursing procedures for brain tumor patients can enable the nurses to plan nursing activities for specific purpose,avoid the occurrence of pressure sore and thus improve the quality of nursing.
