Orthopedic Journal of China 2006;0(04):-
[Objective]To compare the expression of calcitonin gene-related peptide(CGRP) receptor in rat bone marrow mesenchymal stem cells(rBMSCs) and the induced osteoblasts.[Method]The rBMSCs were isolated using whole bone marrow adherence method,and classified into osteoblast-induced group and non-induced group.In the different periods of culturing(1,2,and 3 weeks),identification of osteoblasts was performed by immunohistochemistry and reverse transcriptase-polymerase chain reaction(RT-PCR),and expression of the CGRP receptor was detected by Western Blot and RT-PCR.[Result]RT-PCR test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point,expression of CGRP receptor was increased in a time-dependent manner in the osteoblast-induced groups.Western Blot test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point.Expression of CGRP receptor was increased in a time-dependent manner in osteoblast-induced groups.[Conclusion]According to the mRNA test and protein test,it is suggested that CGRP receptor exists in the rBMSCs.CGRP receptor expression increased in the progress of osteogenic differentiation.

Epstein-Barr virus (EBV)infection is highly prevalent in general population,serum EBV antibody can be detected in about 90% of the adults.Forty years of researches have demonstrated that EBV infection is closely related to a variety of hematological diseases,such as infectious mononucleosis, EBV-related lymphoproliferative disorders,lymphoma and hemophagocytic syndrome.This paper reviews EBV-associated hematological diseases and its pathogenic mechanism.

Objective To summarize the experience of nursing patients with mandibular fractures treated by micro rigid internal fixation.Method The following nursing methods including psychological interventions,pain intervention,dietary intervention, rehabilitation,intervention and prevention of complications were applied in the nursing care to 56 patients with mandibular fractures treated by micro rigid internal fixation.Results The surgical procedures of micro rigid internal fixation were successful,and all of them were cured and discharged.One case contracted gingivitis and another one oral ulcers,both cured by rinse with mouthwash. Conclusion Nursing intervention can improve the rehabilitative effect on patients with titanium mandibular fracture fixation,reduce the complications and improve clinical outcomes.

Objective To assess the value of MRI imaging in diagnosis of the medial collateral ligament(MCL) injury of the knee joint.Methods MR findings of 20 cases of clinically suspected MCL injury of the knee joint were retrospectively reviewed and compared with operative findings of the knee joint.Results In 20 cases of MCL injury,there were 2 cases of gradeⅠinjury,9 gradeⅡand 9 grade Ⅲ.Taking the results of operation as standard,the accuracy of diagnosis of grade Ⅱand Ⅲ injury of the MCL was 88.9% and 100% respectively.Conclusion MRI can accurately display the MCL injury of the knee joint,it is important for the preoperative treatment planning.

The number of root canals varies most in the areas of mandibular anterior teeth, maxillary and mandibular premolars, and premolars. Generally, The mandibular anterior teeth have one root canal, but data suggest that the anatomical morphology of the root canals of mandibular incisors varies greatly, which easily leads to the neglect of root canals in endodontic treatment. This report described the case of a mother and a daughter whose mandibular anterior teeth have two symmetrical root canals.

Objective To compare the effects of sevoflurane and propofol anesthesia on inflammatory response and pulmonary function during perioperative period in patients undergoing lung cancer resection.MethodsThirty ASA Ⅰ or Ⅱ patients(23 male,7 female) aged 41-64 yr having a body weisht index of 22-30 kg/m2 undegoing elective left lower lobe resection were randomlydivided into 2 groups(n=15 each):sevoflurane group (group S) and propofol group(group P).Anesthesia was induced with 6%-8% sevoflurane or propofol 2 mg/kg and fentanyl 4-6 μg/kg.Intubation with double lumen catheter was facilitated with vecuroniunl 0.1 mg/kg. Anesthesia was maintained with 1%-3% sevoflurane/propofol infusion(6-10 mg·kg-1·h-1)and intermittent iv boluses of fentanyl and vecuronium.Radial artery was cannulated.Swan-Ganz catheter was placed via right internal jugular vein.The patients were mechanically ventilated.During one lung ventilation(OLV)I:E and VT were adjusted to maintain airway pressure <30 cm H2O.Arlerial and mixed venous blood samples were collected for blood gas analysis before induction of anesthesia(T0),before OLV(T1),at the end of OLV(T2),when the chest was closed(T3) and at 24 h after operation (T4).PA-aO2,Qs/Qt and respiratory index(RI,PA-aO2/PaO2) were calculated. Serum matrix metallo-proteinase-9 (MMP-9) and MDA were measured at T0, T3 and T4. Dynamic lung compliance (Cd) was calculated at T1-3 .Results PA-aO2, RI and Qs/Qt at T1-3 and serum MMP-9 and MDA concentrations at T3 were significantly increased as compared with the baseline values at T0 in both groups. In group S, Cd was significantly lower at T3 than at T1.PA-AO2, and serum MMP-9 and MDA concentrations at T3, RI at T2,3 and Qs/Qt at T1-3 were significantly higher in group S than in group P. Conclusion The inflammatory response is lower and the injury to pulmonary function is lighter during propofol anesthesia than sevoflurane anesthesia in patients undergoing lung cancer resection.

ObjectiveTo analyze the distribution and density of Langerhans cells and dermal CD68 positive histiocytes in lesions of secondary keloid.MethodsTissue specimens were resected from the lesions of 30 patients with secondary keloid and normal skin of 14 human controls.Immunohistochemistry was performed to observe the expressions of CD68 and CD1a in these specimens.A micrometer was used to count the number of positively stained cells per unit area.The Student's t test was conducted for data analysis by using the SPSS software.ResultsThe density of CD1a+ Langerhans cells was (61 ± 49) cells/mm2 in the epidermis of secondary keloid lesions, (258 ± 61 ) cells/mm2 in the control epidermis,and(40 ± 65) cells/mm2 in the dermis of keloid lesions.CD68+ cells were absent in the epidermis of keloid lesions.Significant differences were observed in the density of CD1a+ Langerhans cells between the lesional and normal control epidermis(t =9.88,P < 0.001 ) and in the percentage of CD68+ cells in nucleated cells between the superficial dermis of lesions and control skin(62% ± 12% vs.70% ± 14%,t =2.66,P < 0.05).The density of dermal CD68+ histiocytes was similar between the lesions and control skin ((287 ± 73) cells/mm2 vs.(290 ± 22) cell/mm2,t =0.02,P > 0.05).Conclusions In keloid lesions,Langerhans cells decrease in the epidermis but increase in the dermis,CD68+ histiocytes are absent in the epidermis,and reduced in the dermis with a declined percentage in nucleated cells.
