Objective To investigation the relationship between health management and prognosis of chronic prostatitis. Methods Three hundied and forty-six cases of chronic prostatitis were divided into two groups. The control group treatment was local washing and medicine for three months. The experiment group treatment was local washing, medicine, and health management for three months. NIH-CPSI was used for the results. Results There was no significant different between the experimental group(165 cases)and the control group(154 cases)before treatment in NIH-CPSI. The effective rate of the the experimental group was 88.5%, and that of the control group was 64.9% after treatment. It is effective for cure and the prognosis of the experiment was better than the control (P<0.05). Conclusion It is suggested that it is more effective for the prognosis of chronic prostatitis after the intervention of health management.

An inflatable liquid epidural balloon was used to simulate an intracranial space-occupying lesion.Two groups of dogs with 8 in each were employed.Under different conditions and time intervals,intracranial pressure(ICP)was continuously recorded,and pressure-volume index(PVI),volume-pressure response(VPR),and cerebrospinal fluid pulse pressure(CSFPP)were measured silmutaneously.It was found that PVI was in significant negative linear correlation with ICP,while VPR and CSFPP in significant positive linear correlation with IVP(P

Objective To introduce the wavelet zero -cross stimulation algorithm and based on which to design and implement the cochlear implants. Methods Through DSP and ICETEK-VC5416, the WZS speech coding strategy was simulated, and also the presented WZS strategy was compared to CIS strategy by hardware implementation and computer simulation. Results The processed audio signals, output from eight channels, were synthesized and played through loudhailer and could be heard with high fidelity. Conclusion The wavelet zero-cross stimulation(WZS) strategy, which generates stimulating pulsatile series at zero-cross points in the domain of wavelet transform, can keep the temporal correlation and coherence of speech remained in stimulating pulsatile series and reflects the characteristic of temporal coding for cochlea.

Objective:To study the effects of LeFort I osteotomy in the treatment of old maxillary fracture.Methods:30 patients with old maxillary fracture were treated with LeFort I osteotomy,the rehabilitation of occluding relation and masticatory function were observed after operation.Results:28 patients had well-pleasing occluding relation and masticatory function; 2 patients dissatisfied with their masticatory function, because of unbalance of nerve-muscle after their occlusal plane were rebuilt.Conclusion:LeFort I osteotomy can be a method in the treatment of old maxillary fracture.

BACKGROUND: Previous research has indicated that both insulin-like growth factor Ⅰ (IGF-Ⅰ) and basic fibroblast growth factor (bFGF) play an important role in cell proliferation and differentiation. However, the effect on biological characteristics of human dental papilla mesenchymal cells (hDPMCs) still remains unclear. OBJECTIVE: To research the effect of IGF-Ⅰ and bFGF on the proliferation and differentiation of hDPMCs.METHODS: hDPMCs were isolated and cultured in DMEM/F12 culture media containing 1% or 10% fetal bovine serum. The fourth-passaged hDPMCs were incubated in culture media containing 0, 0.1, 1, 10 and 100 μg/L bFGF and 0, 25, 50, 75 and 100 μg/L IGF-Ⅰ(0 μg/L as control group), respectively. At 96 hours after culture, proliferative activity was measured with MTT assay. The corresponding growth factor culture media were used in 10 μg/L bFGF group, 100 μg/L IGF-Ⅰgroup, bFGF + IGF-Ⅰ group, and control group, respectively. At days 1, 3, 5, and 7 after culture, the proliferative activity was detected using MTT assay, and alkaline phosphatase (ALP) activity was measured using modified enzyme kinetics method. RESULTS AND CONCLUSION: At the 0-100 μg/L mass concentration scope, both bFGF and IGF-Ⅰcould accelerate proliferation of hDPMCs, and the proliferation ability of bFGF was superior to that of IGF-Ⅰ; moreover, the combination of bFGF and IGF-Ⅰcaused a synergetic action to proliferation of hDPMCs. The maximal valid concentration of bFGF was 10 μg/L, and the maximal action concentration of IGF-Ⅰwas 100 μg/L. At 0-7 days, the effect of bFGF on the ALP activity of hDPMCs was not obvious, but the effect of IGF-Ⅰon ALP activity of hDPMCs became greater with the time passing; furthermore, the combination of bFGF and IGF-Ⅰcould generate a synergetic action on increasing the ALP activity.

To evaluate the influence of different brands of syringes on performance parameters and application quality of syringe pump, we carried out matching experiment of infusion/syringe pump analyzer Rigel Multi-Flo, made by ALK Co. in Sweden, for 3 different types of syringes to measure the flow rate, occlusion alarm pressure, occlusion time and bolus volume of 26 syringe pumps. Data of quality control were analyzed with statistical method. The results demonstrated that there were significant differences in the flow rate, occlusion alarm pressure, occlusion time and bolus volume (P<0. 01) between those of common syringes and original syringes. This study points out that the health care providers should select compatible syringes for syringe pumps, which provides evidence and guidance to assure the reasonable and safe application of syringe pumps in clinical practice.

Objective:To investigate the biological characteristics of dental epithelial cells derived from cervical-loop epithelium in rat lower incisor. Methods:The apical end of the lower incisor was dissected from two-day-old Sprague-Dawley rats by visual microscopy, and dental epithelial cells were obtained by culture of the apical end explants of the lower incisor. The biological characteristics of dental epithelial cells were determined by morphology and immunocytochemistry fluorescence. Results:Dental epithelial cells emigrated from the cervical loop of rat lower incisor, and epithelium-like morphologies with round-shape or square-shape was observed. Dental epithelial cells had a striking proliferation potential with a high level of BurdU labeling. As a marker of epithelium stem cells, P63 expression was observed in most early cultured cells. However, as cells were subcultured, dental epithelial cells,with the lower level of BurdU labeling,decreasing expression of P63 and increasing expression of alkaline phosphatase, were inclined to terminal differentiation.Conclusion:Stem cells or dental epithelial progenitor cells might reside in the cervical loop of the apical end of the rat lower incisor. The present study may provide an excellent cell source for study on the differentiation of dental epithelial cells and tooth regeneration.

Objective:To observe the effects of bone marrow stromal cells(BMSCs)/coral composite strengthened by titanium mesh in the repair of mandibular defects. Methods:The rabbits' BMSCs were cultured and induced in vitro, and then were combined with coral to form the BMSCs/coral composite, which were implanted into the left mandibular defect in the size of 15 mm?8 mm in 16 rabbits. Titanium mesh was used to strengthen and fix the composites. Coral implant was used as the control in the right mandibular defect.Six and twelve weeks after operation, X-ray observation and histological examination were employed to assess the status of bone formation. Results:In the experimental group, new bone formation was found by radiography and the histological examination 6 weeks after operation. 12 weeks after operation woven bone and lamellar bone were observed in the implanted area and the bone defects were repaired, coral was disappeared, titanium was integrated with surrounding bone tissue. In the control group 12 weeks after operation the bone defects were filled by fibrous tissue, coral was disappeared. Conclusion:Titanium /BMSCs/coral composites can repair mandibular defects effectively.

40), the values of BIS, electromyogram (EMG), signal quality index (SQI), mean arterial pressure(MAP), and heart rate(HR) were recorded every minute for 5min, then additional vecuronium (0.05mg/kg) was administered, and the values of the parameters above mentioned were registered for the next 10min. Results BIS value decreased significantly 3 min after the administration of the additional vecuronium (P0.05). Conclusion A misleading BIS value may be caused by the decline of muscle relaxant during the maintenance stage of propofol/fentanyl anesthesia, which greatly influence the accuracy of BIS monitoring.
