Background and Purpose:Kaposi's sarcoma(KS) cases occurring in renal allograph recipients was considered to be due to long-term immunosuppressive therapy.But the exact carcinogenetic process has not been elucidated so far.The lesions could not be distinguished from other KS types by histopathological study.Endemic KS cases seemed to be more common in Xinjiang,especially in the Uygur ethnic group,and their relation to other types of KS was investigated in three cases by histopathology and immunohistochemistry for the present study.Methods:Biopsy specimens from three cases of renal tronsplantation related KS,including two Uygur and one Han patients,were obtained from this hospital(No.474 hospital of PLA).Formalin-fixed and paraffin embedded blocks were cut for routine HE and immunohistochemical staining to study respectively.Monoantibodies of CD34,Ⅷ-factor,Vimentin,actin and FN were detected by S-P techniques for immunohistochemistry.Results:Histopathologically,the typical histology of traditional KS was found in almost all the specimens of the three patients.In the early stage of the disease,there are only a few vessel fissures with irregular dilation and clustering obese(epithelioid)cells.In the middle stage,the changes are wider in scope with proliferation of spindle cells,in the form of beams and weaves.The proliferating vessels are dilated and hyperemic around the lesion.In the late stage,the spindle cells proliferation are markedly atypical,and karyokinesis is increased.Immunohistochemistry showed CD34 to be more strongly positive,Ⅷ-Factor(+),Vimentin(+) showed a weak reation;while actin(-),FN(-) were negative.Conclusions:Renal transplantation related KS is not essentially different from other types of KS both in histopathohogy and immunohistochemical characters which may reflect that they have a similar etiopathogenetic procession.However,the distinctive distribution of morbidity among different ethnic groups or districts strongly suggested that the genetic background plays a critical role on KS carcinogenesis.

Objective To explore the effect of Jisuikang on neural functional recovery, and expression of brain-derived neurotrophic factor (BDNF) protein and mRNA level after spinal cord injury (SCI). Methods 144 female Sprague-Dawley rats, weighted 180 to 220 g, were used for experiment. 24 rats were randomly extracted into sham group (Group A), which had their vertebral plates and spines bitten away only.The others were randomly divided into model group (Group B), prednison group (Group C), and high, middle and low doses of Jisuikang group (Groups D to F) after SCI, 24 rats in each group. Group C was given 0.06 g/(kg ⋅ d) prednison, and Groups D to F were given 50, 25 and 12.5 g/(kg ⋅d) Jisuikang respectively, which were given 20 ml/(kg ⋅d) volume by intragastric administration. Groups A and B were given the same volume of normal saline (NS). The Basso-Beattie-Bresnahan (BBB) scores and oblique board test were applied to test the postoperative results 24 hours, 3, 7 and 14 days after SCI. The rats were executed and the spinal cord tissues were extracted 3, 7 and 14 days after SCI. Immunohistochemistry, Western blotting and RQ-PCR were applied to test the expression of protein and mRNA of BDNF. Results BBB scores and angle of oblique board test were significantly lower in Groups B to F than in Group A 24 hours after SCI (P<0.01). BBB scores were higher in both Groups C and E than in Group B 3 to 14 days after SCI (P<0.05), and was significantly higher in Group E than in the other groups 14 days after SCI (P<0.01). The results of immunohistochemistry and Western blotting showed that the protein expression of BDNF were significantly higher in Groups C and E than in Group B at different time points in the injured area after SCI (P<0.01), while there was no significant difference between Groups C and E (P>0.05). The results of RQ-PCR showed that prednisone and Jisuikang promoted the expression of BDNF mRNA. Group C (prednisone) had a most obvious effect at the beginning while Group E was better than Group C 14 days after SCI. Conclusion Jisuikang can promote the neural functional recovery and the expression of BDNF on both protein and mRNA level in SCI rats.

BACKGROUND:Studies have shown that Clematis chinensis Osbeck can promote articular chondrocyte proliferation, maintain and promote the synthesis of cartilage proteoglycan and type II col agen in chondrocytes. Low-intensity pulsed ultrasound can effectively improve the carticular chondrocyte proliferation, increase the cellmembrane permeability, and promote chemicals or genes delivery, so as to improve the biological effects of chemicals.
OBJECTIVE:To observe the effect of low-intensity pulsed ultrasound mediated Clematis chinensis Osbeck on the proliferation of cartilage cells and the expression of type II col agen and transforming growth factor (TGF)-β1 of rabbit knee articular chondrocytes cultured in vitro, and explore the effect and mechanism of Clematis chinensis Osbeck mediated by low-intensity pulsed ultrasound on cartilage damage.
METHODThe rabbit knee articular chondrocytes were isolated and cultured in vitro. cells of the second generation in logarithmic growth phase were randomly divided into four groupcontrol group, low-intensity pulsed ultrasound (LIPUS) group, Clematis chinensis Osbeck (CCO) group, and CCO+LIPUS group. After cells were cultured under different conditions for 3 days, cellproliferation was measured with cellCount Kit-8 assay. The secretion of type II col agen was detected by cytochemical staining method, and the expression of TGF-β1 was assayed by western blot analysis.
RESULTS AND CONCLUSION:The number of cells in the other three groups were significantly higher than that in control group at 3 days after culture (P<0.05), while the CCO+LIPUS group had the most cells. Cytochemical staining showed that the area and absorbance value of type II col agen in cartilage cells were significantly increased in CCO+LIPUS group, compared with control group (P<0.05), and the difference with control group was larger than the amount of that of LIPUS group and CCO group with control group. Western blot analysis showed that TGF-β1 was significantly expressed in CCO+LIPUS group, and the relative gray value was significantly higher than the other groups (P<0.05). Both low-intensity pulsed ultrasound and Clematis chinensis Osbeck can promote the proliferation of cartilage cells and expression of type II col agen and t-β1 of rabbit knee articular chondrocytes cultured in vitro. The combined method could produce synergistic effects.

ObjectiveTo investigate the changes of serum creatine kinase isoenzyme (CK-MB) and creatine kinase (CK) ratio(CK-MB/CK) and cardiac troponin I(cTnI) simultaneously in patients with acute organophosphorus pesticide poisoning (AOPP) and the clinical value in disease condition judgment.Methods Eight hundred and sixty-eight AOPP patients without disease history of heart,lung,brain,kidney,muscle and other connective tissue were extracted 4 ml of fasting venous blood to determine CK,CK-MB and cTnI simultaneously at 2,12,24,48,96 and 120 hours after poisoning,and the CK-MB/CK was calculated.There were 279 mild poisoning cases (mild poisoning group),289 moderate poisoning cases (moderate poisoning group) and 300 severe poisoning group (severe poisoning group) ; and 208 cases with intermediate myasthenia syndrome (IMS)(IMS group) and 660 cases without IMS (non-IMS group).The result was compared with 288 healthy people (control group) in the same period.Results ( 1 ) The CK,CK-MB and cTnI of mild,moderate and severe poisoning groups between 2 to 12 h,13 to 24 h,25 to 120 h after poisoning were significandy higher than those in control group,CK-MB/CK was obviously lower (P ＜ 0.01 ).The CK,CK-MB,cTnI and CK-MB/CK had significant differences between each two of mild,moderate and severe poisoning groups (P＜ 0.01 or ＜ 0.05).The CK,CK-MB and cTnI of IMS group in 2 to120 h after poisoning were significantly higher than those in non-IMS group,and CK-MB/CK was lower (P ＜ 0.05 or ＜ 0.01 ).In IMS group,the rates of sudden cardiac death (SCD) and multiple organ dysfunction syndrome (MODS) were 23.08％(48/208),37.50％(78/208) respectively,while 4.24％(28/660),9.85％(65/660) in non-IMS group.The incidence of SCD and MODS of two groups had statistical significance (P ＜ 0.01 ).(2) According to IMS and non-IMS group,discriminant equation with independent variables of cTnI (X1), CK (X2) and CK-MB/CK (X3) was established:Y =-0.0014X1 + 0.0225X2 + 65.2376X3,F=21.4911,P ＜ 0.01.The discriminant critical value(Y0) was 2.8124.If Y ＜ 2.8124 belonged to IMS group and Y ≥2.8124 was in non-IMS group,the contribution rates of X1,X2 and X3 were 34.5％,25.4％ and 40.1％ respectively.The coincident rate of return was 91.26％.ConclusionsCK-MB/CK change has negative correlation with poisoning degree of AOPP;cTnI level is positively correlated with AOPP poisoning degree.they may be used to assist the clinical classification,disease judgement and to guide the emergency,treatment and prognosis assessment of AOPP.The function equation with cTnI,CK and CK-MB/CK can be used as effective prediction indexes of IMS,MODS and SCD in early period.

AIM: To investigate the changes of the L-type calcium channel subunit expression and calcium currents (I_~Ca -L) in cultured rat ventricular myocytes infected by coxsackie virus B_3 (CVB_3). METHODS: Primary cultured neonatal rat ventricular myocytes were infected with CVB_3. The changes of L-type calcium channel subunits mRNA in normal and infected myocytes were measured by semi-quantitative reverse transcription-polymerase chain reaction. I_~Ca -L was recorded in two groups respectively using whole cell patch-clamp techniques. RESULTS: The expression of ?_1 and ? subunits of L-type calcium channel mRNA increased in the infected group compared with the normal one (4.00?0.07 vs 2.21?0.41, P0.05). The average current density of I_~Ca -L significantly increased by CVB_3 infection [(-8.66?0.99) pA/pF vs (-6.97?1.75) pA/pF, P

Objective To observe the MRI imaging manifestations of the ligaments and soft tissues around the atlanto-axial joint in children with atlanto-axial rotation instability.Methods Assigned into observation group were 50 children with atlantoaxial rotatory displacement who had been treated in our hospital from January 2013 to March 2014.Another 50 healthy children were chosen as a control group who underwent health check-ups during the same period in our hospital.Both groups received MRI examinations of the ligaments and soft tissues around the atlantoaxial joint using the same equipment and methods.MRI manifestations and characteristics of the ligaments and soft tissues around the atlantoaxial joint were analyzed and compared between the 2 groups.Results In the observation group,odontoid gap asymmetry appeared on both sides,with left shift in 32 cases and right shift in 18 cases.The MRI imaging PDWI sequence showed a significant better diagnostic sensitivity than the other sequences (T1WI,T2WI and SPAIR) (P ＜ 0.05).The MRI examinations on all the children with different sequences found 50 cases of degree Ⅰ lesion in the observation group and 4 cases of degree Ⅰ lesion in the control group,and 12 cases of degree Ⅱ lesion in the observation group and none degree Ⅱ lesion in the control group,showing a significant difference between the 2 groups regarding the diagnostic sensitivity of lesions of degrees Ⅰ and Ⅱ (P ＜ 0.05).Conclusions MRI can clearly show the rotation displacement of atlanto-axial joint associated with transverse ligament,alar ligament and lesions of the surrounding soft tissues.MRI has a dcfinite diagnostic value for atlanto-axial rotation displacements in children,especially those caused by transverse ligament tear after trauma.

Objective To investigate the CT imaging features and its diagnostic value in patients with epibulbar dermoid and dermolipoma. Methods Twelve cases with epibulbar dermoids and dermolipomas were retrospectively analyzed. There were 5 dermoids and 7 dermolipomas, and a distinct female predominance (11/12). The lesions located at the external canthus, and were almost always uniocular and single (right=9, left=3). Transverse plain CT scan was performed in all patients, contrast enhanced CT scan in 5 cases. The clinical aspects, pathological features, and CT findings were then described. Results Crescent-shaped hypodensity lesion attached to the epibulbar was detected in all cases on CT scan. The diameter ranged from 8 mm?5 mm to 25 mm?15 mm. The lesion had a thin wall (1- 3 mm) under the conjunctiva lateral, and could have middle enhancement. Conclusion CT can show the lesion′s range and characteristics, as well as the relationship with the adjacent structures. CT has great directive value for operating on these tumors, and reducing the complications.
