After operation connected intravenous infusion pump analgesia. Results Group S postoperative analgesia was obviously better than the group F,48h abnormal sweating and nausea and vomiting incidence was less than the group F( all P ＜ 0.05). Conclusion The effect of sufentanil combined lornoxicam for hip arthroplasty after intravenous analgesia was better than that of fentanyl combined lornoxicam group and had fewer side effects.

Enforcing microbiology teaching and helping students gain comprehensive knowledge on microbiology have always been the goal for the teachers concerned,since microbiology plays an important role both in theory and in practical life.In microbiology teaching,how to stim- ulate students' interest is crucial to the teaching aim.This article mainly argues four items such as encouraging students participate in teach- ing,employing multimedia,optimizing contents of the textbook and integrating theory,and practice in that teaching.

Objective To observe the effect of postoperative analgesia of flurbiprofen for percutaneous vertebral angioplasty in preemptive analgesia. Methods 40 paifients with ASA Ⅰ - Ⅱ level elective through skin vertebral angioplasty resection patients were seleted and randomly divided into 40 cases, flurbiprofen preemptive analgesia group(group A), and flurbiprofen postoperative analgesia group (group B). Group A was administrated with 50mg flurbiprofen before operation through intravenous, and Group B was administrated with it in the end of operation. By visual analog scale(VAS) ,the score of postoperative 0,1,4,8 and 12h level of pain and postoperative analgesia 24h overall evaluation was assessed. And the additional analgesics and deelop aderse reactions of patients were recorded.Results After operation 24h overall VAS score of group B (1.8 + 0.6) points was above that of group A (3.2 +0. 8) points (P ＜ 0.05). Both groups had no obvious adverse reactions. Conclusion Postoperative analgesia of flurbiprofen for pereutaneous vertebral angioplasty in preemptive analgesia had exact effect,convenience and less adverse reactions.

Objective To improve the current method of spermatogonial cells transplantation, and make the new method become more operative and easy to carry out. Methods The spermatogonial cells in rC57BL6/tg14 (act-EGFO-Osb Y01) mice that expresse GFP protein were collected as the donor cells, and by using a modified syringe, and then were injected into the seminiferous tubules of pretreated wild type GFP-null mice through testicular efferent duct. The transplantation outcome was evaluated by trypan blue stainting and fluorescent microscopic examination and pathohistological analysis of transplanted testis. Results The transplanted testis of recipient mice showed green fluorescence signal, and the signal of seminiferous tubules was found significantly higher than that of the surrounding tissues. The transplanted GFP-positive cells generated colonies and spermatogenesis but pretreated wild type GFP-null mice were not found. Conclusion The expressed GFP protein spermatogonial cells in rC57BL6/tg14 mice were successfully transplanted in the wild type GFP-null recipient mice, fourthermore the improved transplantation method simplified the triditional one and achieved the same transplantation results.

Objective To study the influence on T-lymphocyte subsets in herpes zoster with adjuvant treatment of compound glycyrrhizin.Methods 93 patients with herpes zoster were randomly divided into two groups:control group(46 cases,treated with antiviral drugs) and 1 treatment group(47 cases,treated with compound glycyrrhizin and antiviral drugs).The expression of T-lymphocyte subsets on the T cell surface in patients and control group were determined by flow cytometry.Results The expression of CD3,CD4,CD8,CD4/CD8 ratio was significantly different in the treatment group and control group.Conclusion Compound glycyrrhizic adjuvant therapy could not only shorten check blister,acetanilide,scar tissue and recovery time,reduce the sequela of neuralgia,but also affect the expression state of T lymphocyte subsets with herpes zoster,improve the cellular immune function with herpes zoster.

ObjectiveTo explore the efficacy of large trauma craniotomy with bilateral frontal coronal incision in treating contusion and laceration of bilateral frontal lobes.MethodsThe clinical data of 68 patients with contusion and laceration of bilateral frontal lobes who were treated with bilateral decompressive craniectomy were analyzed retrospectively.There were 36 cases(observation group) treated with large trauma craniotomy with bilateral frontal coronal incision and 32 cases (control group) given bilateral decompressive craniectomy by stages.The prognosis of two groups were observed and compared.The prognosis was evaluated at 6 months after surgery by Glasgow outcome scale (GOS) score.ResultsThere were 23 cases (63.89％,23/36) who got good recovery,8 cases(22.22％,8/36) with poor prognosis and 5 dead cases (13.89％,5/36) in observation group.There were 11 cases (34.38％,11/32) who got good recovery,9 cases (28.12％,9/32) with poor prognosis and 12 dead cases (37.50％,12/32) in control group.The rate of good recovery and mortality between two groups had significant differences (P ＜ 0.05).ConclusionsThe large trauma craniotomy with bilateral frontal coronal incision can significantly relieve or ease intracranial hypertension of patients with contusion and laceration of bilateral frontal lobes.And it can improve the prognosis and decrease the mortality.

Objective To compare the biocompatible and osteconduetian behavior of the high-density porous polyethylene and hydroxyapatite/ultra-high molecular weight polyethylene. Methods Osteoectomy of the upper orbital rim was performed on 60 adult Japan rabbits. The animals were randomly divided into 3 groups with 20 of each. The hydroxyapatite/ultra-high molecular weight polyethylene, high-density porous polyethylene was implanted to the upper orbital defect of the animals in respective group. Animals were sacrificed at the 1st, 2nd, 4th and 8th weeks. Alkaline phosphatase (ALP) and Osteocalcin (OC)in the HDPE and hydroxyapatite/ultra-high molecular weight polyethylene was also detected. Result During the experimental period of 8 weeks, there was no implants extrusion or displacement. Fibrous tissue and new vessels grew into HDPE were obviously elder than those grew into hydroxyapatite/ultra high molecular weight polyethy-lene. Alkaline phosphatase and osteocalcin contents has great difference, HDPE group is the best, followed by HA combination artificial group (P<0.05). Conclusions High-density porous polyethylene and hydroxyapatite/ultra-high molecular weight polyethylene are both good orbital reconstruction materials, they all have good biocompatiblity and osteoconductian, but high-density porous polyethylene is better than hydroxyapatite/ultra-high molecular weight polyethylene in osteoconductian.

Objective To investigate the levels of inflammatory cytokines in children with low absolute lymphocyte count (ALC).Methods 56 patients with low ALC as the patients group and 20 children with healthy physical examination as the control group were enrolled.Several inflammatory cytokines,namely IL-1,IL-6,IL-8 and TNF-βwere measured with enzyme linked immu-nosorbent assay(ELISA)kits.High sensitive C reactive protein(Hs-CRP)was measured by the immunoturbidimetry(ITM)kit with the automatic biochemical analyzer.Results The concentrations of IL-1,IL-6,IL-8 and TNF-βin the patients were(0.096±0.012) ng/mL,(0.118±0.026)ng/mL,(0.388 ±0.069)ng/mL and(1.256 ±0.245 )ng/mL respectively,which had no statistical differ-ences as compared with the control group(P >0.05);the concentration of HsCRP in the patients group was(5.7±2.8)mg/L,while which in the control group was(4.8±2.6)mg/L,showing no statistically significant difference between them(P >0.05).Conclusion The levels of the cytokines in low ALC patients are not increased,which may be related with the other factors.Actively using tra-ditional Chinese medicine treatment is beneficial to the recovery of disease.
