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.

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.

Objective To analyze the implementation effects of peer-assisted learning on critical thinking ability of undergraduate nursing students. Methods A total of 411 college nursing students were selected with 203 students of Class One, Class Three, and Class Five from Grade 2012 majoring in nursing were taken as the control group, 208 students of Class Two, Class Four, and Class Six as the experimental group. In the course of basic nursing practice, the control group was trained by the traditional practice, and the experimental group was trained by the way of peer mutual aid. Critical thinking disposition inventory Chinese version (CTDI-CV) was adopted to evaluate the level of critical thinking ability of the nursing students of both groups. SPSS 17.0 was used and the data of the two groups were compared by t test. Results The score of experimental group students' critical thinking ability and the score of 7 dimensions including their seeking truth, analysis ability, self-confidence, inquisitiveness, cognitive maturity, open mind and systematic ability were higher than those before the experiment (P<0.05). The total score of the experimental group students' critical thinking ability and the score of 5 dimensions including seeking truth , analysis ability, self-confidence, curiosity and cognitive maturity were higher than those of the control group (P<0.05). Conclusion Peer-assisted learning is beneficial to the improvement of critical thinking ability of nursing undergraduate students.

Objective:To examine the effects of acute or chronic administration of 7-nitro indazole (7-NI) on the MAC of sevoflurane and cerebellar cGMP levels in mice. Method:In acute experiment,sevoflurane MAC was determined in mice after 7-NI 120mg/kg, 180mg/kg or 120mg/kg plus L-arginine 600mg/kg was given intraperitoneally. During chronic experiment, MAC was measured on 1st, 4th and 7th day during week-long gavage feeding of 7-NI. The levels of cerebellar cGMP also were measured after acute and chronic administration of 7-NI. Result:Acute administration of 7-NI 120mg/kg decreased sevoflurane MAC by about 20% and cerebellar cGMP level by 96%. 7-NI 180mg/kg did decrease MAC not more than 7-NI 120mg/kg. No significant reduction of MAC was observed in mice treated by intraperitoneal 7-NI 120mg/kg+L-arginine 600mg/kg. In chronic experiment,sevoflurane MAC and cerebellar cGMP were decreased significantly on 1st 4th and 7th day to the similar extend, with 15%-20% reduction in MAC and 46%-60% in cGMP levels. Conclusion:Acute and chronic selective inhibition of nNOS decreases sevoflurane MAC and cerebellar cGMP levels in mice. The maximal reduction (only about 20%) of MAC can be obtained when cGMP levesl are decreased about 50% and further inhibition of generation of cGMP does not produce more enhancement to the potency of sevoflurane anesthesia. No compensatory mechanism for the inhibition of L-Arg-NO-cGMP pathway appears during week-long treatment with 7-NI.

Objective To compare the analgesic and side effects of tramadol, buprenorphine and morphine in equipotent dosage in patient-controlled intravenous analgesia (PCIA). Methods 53 patients (ASA I-II) scheduled for upper abdominal surgery were randomly allocated to receive 10mg/ml tramadol (group T) or 0.03mg/ml buprenorphine (group B) or 1mg/ml morphine (group M) plus 0.1mg/ml droperidol. Baxter APII PCA pump was used to administer the different analgesic according to the model of LCP, with the amount of loading dose, continuous infusion and bolus of 2.5ml, 0.5ml/h, 1ml respectively. At 4, 8, 16 and 24h postoperatively, pain scores in VAS, comfort scale in BCS, sedation scores with Ramsay score, and the incidences of nausea, vomiting, pruritus, respiratory depression were assessed. Drug consumption in the first 24h and the D/D ratio (demand/deliver) were also recorded. Results VAS and BCS scores showed no significant difference among the 3 groups, but drug consumption within the first 24h and the D/D ratio in group T were higher than those in other 2 groups (P0.05). 8 patients in group T, 5 in group B and 4 in group M suffered from nausea; 1 patient in group T, 2 in group B and 3 in group M complained of pruritus. No respiratory depression was observed in all cases. Conclusion Tramadol and buprenorphine can be safely used as PCIA in patients undergoing upper abdominal surgery, but they are not superior to morphine.
