BACKGROUND:Al ogenic bone is a clinical commonly used bone graft material, but the osteoinductive capacity is the biggest problem. OBJECTIVE:To evaluate the effect of al ogeneic bone combined with autologous bone marrow stem cells on the repair of bone defects after scraping or resection of benign bone tumors and tumor-like lesions. METHODS:Sixty-five cases of benign bone tumors (including patients with tumor-like lesions) were divided into two groups according to bone graft. There were 35 cases in the composite bone marrow stem cells for bone graft group, and 20-40 mL red bone marrow were extracted from anterosuperior iliac spine or iliac spine on both sides according to the expected amount of bone graft, then the bone marrow stem cells were isolated, purified, cultured and amplified for standby, and the bone marrow stromal stem cells and al ogeneic bone particles were ful y blended before bong graft. After tumor scraping or resection, the blended bone marrow stromal stem cells and al ogeneic bone particles were implanted into the bone defect region. In the bone graft group, the bone defect was implanted with al ogeneic bone soaked with saline for half an hour. X-ray examination was performed at 1, 3, 6 and 12 months after treatment to compare the fuzzy boundary and the time for disappear, and the postoperative complications were observed. RESULTS AND CONCLUSION:Al the 62 patients were fol owed-up for more than 12 months. The fuzzy boundary time and disappear time in the composite bone marrow stem cells for bone graft group were shorter than those in the bone graft group (P<0.05). In the composite bone marrow stem cells for bone graft group, one case appeared rejection and healed after treated with immunosuppressive agents for 2 weeks, and no complication observed in two groups. The results indicate that al ogeneic bone composite autologous bone marrow stem cells for bone graft can promote bone fusion and bone defect healing.

BACKGROUND:With the wide application and in-depth research of artificial hip joint, more secondary fractures around femoral prosthesis are reported. OBJECTIVE:To investigate the reasons, preventive measures, classification and treatment method of fractures around femoral prosthesis after artificial hip replacement. METHODS:The clinical data of the type classification, treatment method and clinical efficacy of fractures around femoral prosthesis after artificial hip replacement were retrospectively analyzed. The multi-level study was performed to investigate the trend of the relevant literatures. According to the Vancouver classification criteria, the various types of fractures and the results and complications of various treatment methods were analyzed, the treatment methods of different fractures were identified, and the effective and objective evaluation criteria were established to provide references for the clinical treatment. RESUTLS AND CONCLUSION:The fractures around femoral prosthesis after artificial hip replacement were closely related with the age of the patients, basic diseases, osteoporosis and selection of prosthesis type. The Vancouver classification criteria and treatment programs have guiding significance to the clinical efficacy. The fractures should be treated with different methods according to the different types in order to promote the fracture healing. The fractures around femoral prosthesis after artificial hip replacement were commonly treated with shape memory alloy embracing fixator, minimal y invasive fixation system, locking compression plate, al ograft cortical bone plates, carbon fiber, impaction bone grafting and renovation. In the practice application, various methods are often used in combination. For the patients with B2 and B3 type fractures, we should pay attention to the bone grafting around the fractures and the inner and outer medul ary cavity.

Background Accurate measurement of corneal thickness is very important during the pre-and post-operative management of corneal surgical procedures,especially laser-assisted in-situ keratomileusis (LASIK),which is the most popular approach to the correction of refractive errors currently.This may be particularly important for the patients who have undergone previous laser refractive surgery with suboptimal outcomes and are being considered for an enhancement procedure.Objective This study was to compare the measuring outcomes of corneal thickness by slit-scanning pachymetry,non-contact specular microscope,anterior segment optical coherence tomography (AS-OCT)and ultrasound pachymetry,with a focus on central and midperipheral (from the central 3.0 mm) region of cornea in post-LASIK eyes.Methods Sixty-four right eyes of 64 patients who received LASIK were collected in Henan Eye Institute,Henan Eye Hospital from March to June 2011 with the equivalent spherical diopter of (-4.75±2.38)D and horizontal corneal diameter of (11.36±0.32)mm.Central corneal thickness was measured on each eye by using non-contact specular microscope (Topcon SP-3000P),slit-scanning pachymetry (Orbscan Ⅱ),AS-OCT and A-type ultrasound pachymetry,respectively,and the paracentral corneal thickness including 12:00,2:00,6:00 and 10:00 meridian was measured using Orbscan Ⅱ,non-contact specular microscope and AS-OCT.The measuring values and the agreement from different instruments were compared and evaluated.Results The mean central corneal thickness was (467.12±31.10)tμm for AS-OCT,(466.67±30.99)μm for ultrasound pachymetry,(441.84 ± 33.65) μm for specular microscopy and (422.51 ± 44.09) μm for Orbsan Ⅱ,respectively,showing a significant difference among the four methods (F =23.730,P =0.000).The central thickness value of the A-type ultrasound pachymetry was significantly higher than that of Orbsan Ⅱ or non-contact specular microscope (q =6.940,6.720,both at P =0.000).Compared with Orbscan Ⅱ,the measuring values of non-contact specular microscope and AS-OCT were significantly higher (q =-5.54,6.940,both at P =0.000),and the measuring value of AS-OCT was significantly higher that of non-contact specular microscope (q =6.800,P =0.000).The lowest difference value (25.3 μm)and the best agreement was found between the ultrasound pachymetry and AS-OCT.The paracentral corneal thickness values in 12:00,2:00,10:00,6:00 meridians were highest for Orbsan Ⅱ and the next for AS-OCT,and non-contact specular microscope had the lowest values,with significantly differences among them (F =5.020,22.950,67.890,18.850,all at P ＜ 0.01).Conclusions The corneal thickness values vary with the different instruments.Orbsan Ⅱ underestimates the central corneal thickness and overestimates the midperipheral corneal thickness,and non-contact specular microscope underestimates both the central and midperipheral corneal thickness.The measuring outcome from AS-OCT has a good agreement with ultrasound pachymetry and therefore they can be used interchangeably.

Objective To investigate the effects of component combination in Siwu Decoction (CCSWD) on the proliferation of human bone marrow stromal cell lines HFCL and hematopoiesis-related gene expression and to probe into the mechanism of the stimulative effects of SWD and CCSWD on the proliferation of HFCL cells. Methods MTT and FCM were used for assaying the proliferation potency and cell cycle of HFCL cells, respectively. A human hematopoiesis-related cytokine oligonuleotide microarray was prepared to investigate the diversity of gene expression of HFCL cells in SWD and CCSWD groups. Results The energy metabolism and proliferation potency of HFCL cells treated with CCSWD were more prompted than that of the control group. Meanwhile, the percentage of HFCL cells in G 0/G 1 phase treated with CCSWD was significantly lower, while the proliferation index (PI) was higher than that of the control group. Compared to the control group, expressions of IL 2-R?, NF-?B, and TPO were up-regulated in CCSWD group.Conclusion The proliferation of HFCL cells could be facilitated by CCSWD with up-regulating the expressions of IL 2-R?, NF-?B, and TPO.

Traditional Chinese medicine (TCM) has an important role in the prevention and treatment of this disease. Through clinical epidemiological survey, a deeper understanding of TCM etiology and syndrome characteristics in CAD would further improve clinical efficacy in the treatment of this disease.

Objective To evaluate the PDCA cycle on the rehabilitation of postoperative patients with anal fistula, aiming at improving the recovery of patients and preventing recurrence. Methods 144 postoperative patients of anal fistula were randomly divided into the observation group and the control group with 72 cases in each group. The observation group received intervention based upon the PDCA cy-cle, and the control group was given the traditional oral propaganda. The recovery time, recurrence rate, mastering of education content and self-control ability were compared in the two groups using t test and χ2 test. Results The mastering level of education content and the self-management skills in the observation group were superior to those of the control group. After 3 to 24 months of follow-up, the observation group showed shorter recovery time and less recurrence rate than that of the control group. Conclusions Nurs-ing intervention based upon PDCA cycle can strengthen the patients' mastering of related knowledge, pro-mote the recovery, reduce recurrence rate and improve the patients' quality of life.

Objective To investigate the mechanisms of astrocytes modulating neurons in rat supraoptic nucleus induced by hypotonic stimulation and the effect of 6-aminomethyl-3-methyl-4H-1,2,4-benzothiadiazine-1,1dioxide HCl(TAG,a antagonist for taurine) or carbenoxolone(CBX,a gap junction blocker)on the responses of astrocytes and neurons in SON.Methods Adult male Sprague-Dawley rats were divided into four groups: the control group was injected with 5.5ml/kg 0.9% NaCl solution into the caudal vein;the hypotonic group was injected with 5.5 ml/kg hypo-saline(0.83% glucose plus 0.3% NaCl);TAG + hypotonic and CBX + hypotonic groups were injected with TAG(100?mol/L) or CBX(10g/L) into the lateral ventricle respectively,and were injected 2 hours later with hypotonic saline into the caudal vein.With anti-Fos,anti-vasopressin(VP),anti-glycine receptor(GlyR),anti-glial fibrillary acidic protein(GFAP) and anti-connexin43(Cx43) immunofluorescent staining methods,the responses of neurons and astrocytes in SON were studied.Results In control rats,Fos-,VP-,and GlyR-expression in the neurons and GFAP-or Cx43-expression in the astrocytes were lower.In hypotonic rats,GFAP-,Cx43-and GlyR signals were more than those in control rats,while Fos-and VP-signals were less.Compared with those in hypotonic rats in TAG + hypotonic or CBX + hypotonic rats,GFAP-and Cx43-signals in the astrocytes were the same,GlyR-signals in the neurons decreased,and Fos-and VP-signals increased.Conclusion Hypotonic stimulation activates SON astrocytes,which then release taurine through gap junction signaling to the neurons and inhibit the release of VP from the neurons.
