BACKGROUND:Previous studies have applied long-bone mechanical separation method to obtain osteoclasts, which are terminal y differentiated cells and cannot further proliferate. Therefore a large number of osteoclasts can be harvested with bone marrow cells inducing culture method and RAW264.7 cells inducing culture method to meet clinical requirements.
OBJECTIVE:To investigate the optimal method of receptor activator of nuclear factor kappa-B ligand (RANKL) induced osteoclast precursors to differentiate into mature osteoclasts.
METHODS:After bone marrow cells were isolated from mouse, RANKL and macrophage colony stimulating factor were added into the medium together, or RAW264.7 cells were cultured with RANKL to induce osteoclasts. The osteoclast precursors were treated with different concentrations of RANKL to observe the number of generated osteoclasts and evaluate the dose-effect relationship between RANKL and osteoclastogenesis. Annexin V-FITC and propidium iodide staining were used for flow cytometry to analyze the mononuclear-macrophage apoptosis during osteoclastogenesis.
RESULTS AND CONCLUSION:When 10μg/L RANKL was used, the peak of osteoclastogenesis appeared at days 6-7;when the concentration of RANKL was up to 100μg/L, the peak appeared at days 4-5. The number of new osteoclasts was dose-dependent on the RANKL concentration. 50μg/L of RANKL was the turning point in the fitted curve from osteoclastogenesis and RANKL concentration. After the RANKL concentration was more than 150μg/L, the number of osteoclasts slowed down obviously. RANKL can induce monocyte-macrophage to form osteoclasts and promote monocyte-macrophage apoptosis. The highest number of osteoclasts would be obtained to each unit of RANKL when monocyte-macrophage cells were cultured with 30μg/L of RANKL in the same vaccination density (104/cm2). Experimental findings indicate that, RAW264.7 cells or bone marrow cells inducing culture methods are simple and feasible, the optimum cellseeding density was 104/cm2;the appropriate stimulation concentration of RANKL was 30-50μg/L.

OBJECTIVETo explore treatment effect of the locking plate percutaneous external fixation to tibial fractures.

METHODSFrom July 2010 to February 2013, 8 cases with pediatric tibial fractures were treated by using unilateral locking plate percutaneous external fixation,including 6 males and 2 females with an average age of 7 years old ranging from 4 to 10. Among them, 5 cases were open fractures involving 1 case of Gustilo-Anderson type II, 3 cases of type III A, 1 case of type III B; and the other 3 cases were closed fractures involving 2 cases of AO type A3, 1 cases of type B2. The postoperative bone healing and gait impact were observed and the function was evaluated by Johner-Wruhs scores.

RESULTSAll fractures healed successfully without infection. The fracture healing time was from 3 to 6 months with an average of 3.9 months. The locking plate removal time was from 4 to 7 months with an average of 4.3 months. Among them, 7 cases were visually normal after walking with stand, 1 case of anterior tibial tendon defect affected gait. The results of Johner-Wruhs assessment were excellent in 7 cases, good in 1 case. No rub contralateral medial calf skin wounds occurenced.

CONCLUSIONThe method is simple, stable and reliable. The fixation strength is suitable for children using locking plate percutaneous external fixation. The postoperative functional recovery was excellent and the walking gait was less affected. But the point of LCP pedicle screw should be carefully selected before installation with good skin coverage.

Objective To evaluate the role of 5-HT5A receptors (5-HT5A R) in activation of astroglia in the spinal dorsal horn in a rat model of neuropathic pain induced by vincristine. Methods Forty adult male SD rats weighing 180-200 g were randomly divided into 4 groups ( n = 10 each): control group (group C);neuropathic pain group (group P);Ad-X-HK group (group B) and Ad-5-HT5A-siRNA group (group S). Neuropathic pain was induced by repeated intraperitoneal (IP) injection of vincristine 0.1 mg/kg according to the method described by Weng et al in group P, B and S. On the 2nd day after the last IP injection, the animals received artificial cerebrospinal fluid, Ad-X-HK and Ad-5-HT5A-siRNA 25 μl administered intrathecally (IT) in group P, B and S respectively. Paw withdrawal threshold to mechanical stimulus was measured before and on the 7th day after IT administration. The animals were then sacrificed. The lumbar segment ( L4.5 ) of the spinal cord was removed for determination of 5-HT5A R and GFAP expression. Results Body weight and paw withdrawal threshold were significantly decreased after repeated IP vincristine administration in group P compared with group C. IT Ad-5-HT5A-siRNA reduced pain threshold further in group S compared with group P. Repeated IP vincristine significantly increased the expression of 5-HT5A R and GFAP in spinal dorsal horn, and IT Ad-5-HT5A-siRNA significantly decreased the expression of 5-HT5A R while increased the expression of GFAP in spinal dorsal horn in group S compared with group P. Conclusion 5-HT5AR is involved in the inhibition of astrocyte activation, resulting in reduction of vincristineinduced neuropathic pain.

Objective To explore the change characteristics of physiological indexes between infants and children during living-donor liver transplantation and discuss methods of regulation and control.Method In this study,42 patients were selected and assigned into two groups according to age:infants group (＜1 year,n =25),and children group (1-16 years,n =17).The preoperative and peri-operative characteristics,intra-operative operation conditions,internal environment changes before and after re-perfusion,postoperative mechanical ventilation time,ICU time,hospital time,infection rate,additional surgery,complications and survival were analyzed.Result PELD (MELD) score,historical surgery rate and hematokrit were lower in children group than in infants group (P＜ 0.05).Serum creatinine and lactate concentrations increased significantly in children group as compared with infants group (P＜0.05).Intra-operative an-hepatic phase and cold ischemia time were shortened significantly (P ＜ 0.05),and incidence rate of re-perfusion syndrome was reduced in children group as compared with infants group (P＜0.05).As compared with pre-re-perfusion,blood lactate concentrations were significantly raised only in infants group and glucose concentrations significantly raised only in children group (P＜0.05).The blood levels of K + were decreased after reperfusion in both two groups,and those in infants group were lower than in children group (P＜ 0.05).Postoperative intensive care unit time was longer in children group than in infants group (P＜ 0.05),and there was no significant difference in survival rate between two groups.Conclusion There are many differences and change characteristics to physiological indexes between infants and children during the operation of living-donor liver transplantation.Timely management and regulation are critical for the success of surgery according to the differences.

OBJECTIVE:To discuss the effect of performance management in medication consultation service in hospital,and to improve the service quality in medication consultation center. METHODS:The performance management mode of medication consultation center was implemented in our hospital through formulating consultation pharmacist performance evaluation content and accounting rules from four dimensions of business skills,cultural literacy,work attitude,workload,conducting daily evaluation and check,developing training,setting development plan,etc. The effects of the mode were evaluated. RESULTS:In performance evaluation,business skills,cultural literacy,work attitude and workload took up 20,15,15 and 50 points,respectively;they were subdivided into 16 specific items and extra point items. After the implementation of above performance management,average weekly clients increased from 104 persons to 247 persons (increasing by 138%);the proportion of patient medication education mainly provided by clinical pharmacists increased from 18.30% to 46.34%(increasing by 153%);the complex and professional problems of medication consultation such as drug interaction rose from 0.96% to 5.28%;the problem of drug usage and dosage in-creased from 6.73% to 23.17%. The performance management mode not only improved the service consciousness and the enthusi-asm of consultation pharmacists,but also improved the level of pharmaceutical care. CONCLUSIONS:Reasonable and effective performance management mode can promote the service quality and ability of medication consultation center,and play more impor-tant role in hospital pharmaceutical care.

[ABSTRACT]OBJECTIVETo evaluate the accuracy of the watch peripheral arterial tone (Watch-PAT) in the diagnosis of obstructive sleep apnea hypopnea syndrome (OSAHS).METHODSA total of 51 outpatients who had chief complaint of sleep snoring were carried out Watch-PAT test and polysomnography (PSG) simultaneously, and the results were statistically compared.RESULTSFifty one patients, consisted of 44 males and 7 females, had the mean age of (45.7±12.0) years (±s) and the mean body mass index of (28.8±3.6) kg/m2.The mean PSG apnea hypopnea index (AHI) was (45.69±12.02) events per hour, and mean Watch-PAT AHI was (35.49±24.49) events per hour. Significant correlation has been detected between Watch-PAT AHI and PSG AHI (r=0.878,P<0.001). The sensitivity and specificity of Watch-PAT were 97.73% and 85.71%, when PSG-AHI≥5/h events per hour was setting as the threshold value to diagnose OSAHS. The diagnostic efficiency of Watch-PAT has been tested by ROC curve, and the area under the curve approached to 0.997.CONCLUSIONThe Watch-PAT was proved as a portable and reliable device of screening patients who were suspected OSAHS.

Objective To analyze and discuss the possible reasons of the bone resorption beneath the prostheses after chin augmentation.Methods Twelve patients were admitted to our department for further correction after chin augmentation with materials.The bone resorption was observed through the clinical research and X-ray examination.Results All the patients were underwent the removal of the materials,genioplasty was performed in 8 patients,and two patients were treated by chin augmentation with polyethylene.All the patients were satisfied with their facial contouring.Mild bone resorption was found in seven patients (depth of bone resorption ≤2 mm),in which five patients were used with silicone materials,two patients were performed with expanded polytetrafluoroethylene implants.Moderate bone resorption was seen in three cases.All of them were used with silicone implants (2 mm ＜ depth of bone resorption ≤4 mm).Severe bone resorption happened in two patients (depth of bone resorption ＞4 mm).One was used with silicone implant,and the other one was carried out with expanded polytetrafluoroethylene implant.Conclusions The imbalance among mentalis muscle,materials and underlying bone might be one of the key reasons.Thus for mild and moderate microgenia cases,chin augmentation with material is suitable,while long-term fellow-up study is necessary.But for the cases of severe mirogenia or microgenia and micrognathia with dentofacial deformity or mentalis muscle hyperactivity,genioplasty might be performed as well to correct their deformities.
