AIM: To observe the changes of Ca-L current (ICa-L) and to investigate the mechanism of salvia miltiorrhizae (SM) for eliminating Ca~2+ overloaded in cells during acute hypoxia/reoxygenation. METHODS: The whole cell patch clamp technique was applied to study the changes of ICa-L. Different concentrations (32, 320, ~3 200 mg/L) of SM were added to the ventricular myocytes isolated from guinea pigs by enzyme digestion. RESULTS: SM (32, 320, ~3 200 mg/L) decreased the amplitude of ICa-L in a concentration-dependent manner regardless of these cells were under normoxia, hypoxia or reoxygenation. Furthermore, SM at low concentration (32 mg/L) was more effective to hypoxia or reoxygenation-treated cells than that to the cells under normoxia condition. CONCLUSION: These results indicate that SM effectively decreases the abnormal raised amplitude of ICa-L in ventricular myocytes under hypoxia or reoxygenation conditions, preventing Ca~2+ overloaded in the cells.

The present situation and the deficiencies of high-value medical consumables were analyzed. Two-dimensional barcode technology was suggested to be involved in the whole-course dynamic tracing of the high-value consumables to combine the high-value consumables information with the patient information. The course included the links of acquisi-tion, warehousing, barcode preparation, delivering and charging. Two-dimensional barcode technology may enhance the medical consumables management and decrease medical dispute, and thus contributes to the development of digital hospi-tal.

Objective To evaluate the the brow position and shape in young Chinese women using a photography measurement.Methods A total of 100 Chinese women aged 20 to 30 years were photographed to determine the distance between brow and eye.Measurements were made from a horizontal plane through the lateral canthus of right eye to three vertical points on the upper brow margin at the medial canthus,lateral limbus of the iris,and lateral canthus.Results The distance between brow and eye in young Chinese women was 2.12,2.52 and 2.46 cm at medial canthus,lateral limbus of the iris and lateral canthus,respectively.The distances were higher between the brows and eyes at lateral limbus of the iris and lateral canthus than that at medial canthus (P＜0.05).Conclusions The measurement used in this study is a simple and practical quantitative method.The results can be used to guide the surgical choice and help to evaluate the surgical techniques.

Objective The purpose of this study was to investigate the feasibility of short tandem repeat(STR) genotyping of cell free DNA in plasma for individual identification and paternity testing. Methods EDTA-Na2 DNA anti-coagulant blood samples were collected from 36 unrelated healthy volunteers,and both DNA in leukocytes and cell free DNA in plasma were extracted respectively using phenol-chloroform method. Target DNA in blood cells and plasma were amplified using regular STR typing and fluorescent multiplex STR assay separately,accordingly,the PCR products were analyzed by polyacrylamide gel electrophoresis and capillary electrophoresis. Results Using either normal PCR-STR or fluorescent multiplex STR assay,the consistent STR genotyping results were detected with similar efficiency for cell DNA and plasma DNA samples from the same individual. Conclusion Cell free DNA in plasma samples can be used as useful biological samples for STR genotyping,which can be applied to individual identification and paternity testing in forensic practice.

Objective To summarize the types and imaging features of periosteal anomaly in osteosarcoma.Further to seek the feature of genesis and advancement of periosteal anomaly and its clinical significance.Methods One hundred and twenty-eight patients with osteosarcoma were enrolled in this study,which consisted of 76 males and 52 females aging from 5 to 66 years old with an average of 19 years.Both x-ray plain film and MR images were obtained in all patients.and DWI were done in 23 patients.CT scanning was conducted in 48 patients.which included post-contrast scanning done in 36.The pathological gross specimen,macrosection and point-to-point microsection were obtained in each of 14 cases to correlate the imaging findings of periosteal anomaly to the pathological outcome.Results The imaging and pathological finding:(1)Periosteodema,occurring in 96 patients.The sign was merely demonstratable on MR image and presented as loosened periosteal structure with no tumoral infiltration pathologically.(2)Periosteal lift and thickening,demonstratable on both CT and MR image,including 13 noted on CT and 42 on MR image.Pathologically,non-tumoral infiltration was noted in the thickened periosteum.(3)Periosteal destruction,occurring in 48 patients.Periosteal destruction was merely demonstratable on MR image and presented as localized or generalized tumoral infiltration of the periosteum.(4)Linear periosteal neo-bone formation,demonstrated in 42 cases on plain films,13 cases on CT and 22 on MR images,respectively.The linear periosteal neo-bone formation was pathologically regularly arranged periosteal neo-bone.(5)Laminar periosteal neo-bone fomarion,demonstrated in 21 cases on plain films,6 cases on CT and 21 on MR images,respectively.Pathologically,it appeared as multi-layer arrangement.(6)Radiated and spiculate periosteal neo-bone formation,demonstrated in 13 cases on plain films,7 cases on CT and 14 on MR images,respectively.On both plain film and CT,the closer to the center of the tumor,the longer and denser the spicule was.The interspiculate structure was tumoral tissue pathologically.(7)Periosteal neo-bone formation of mixed type,demonstrated in 7 cases on plain films,4 cases on CT and 8 on MR images,respectively.It was composed of 2 types or more of periosteal neo-bone.Conclusions (1)Multiform periosteal anomaly can be induced by osteosarcoma,and difierent periosteal anomaly possesses different imaging findings and different pathological basis.(2)The pathologically-based classification of periosteal anomaly generalizes the 3-modality imaging findings of various periosteal pathological alterations.(3)MR imaging enables to demonstrate periosteal anomaly more early,and periosteodema and periosteal destruction without neo-bone formation can only be demonstrated by MR imaging.MR imaging is more sensitive than CT in displaying periosteal thickening.

Objective To study radiological characteristics of hand-foot-mouth disease(HFMD) in children. Methods The chest X-ray films of 1295 children patients of HFMD were analyzed,for the general X-ray manifestations and the evolution. Results A total of 1427 films was obtained from all patients, in which 1203 cases were normal and 224 cases were abnormal. The interstitial changes characterized the abnormal group, mainly as increased and vague lung markings, increased hilar shadows (137 cases).The parenchyma changes appeared as patchy exudative shadows(49 cases). Short-term dynamic observation was applied in 62 cases, 38 cases pulmonary disease progression manifested as normal and the interstitial type changing into the parenchyma type and the mixed type, the localized type changing into the diffuse type. Conclusions Most children patients of HFMD showed normal chest films, while the abnormal patients were characterized by interstitial and parenchyma pulmonary edema. Serial chest X-ray examination and short-term dynamic observation were important to identify the severe cases and assess patients' condition.

Objective To probe the imaging diagnostic characteristics of skull base-type pituitary adenoma (SBPA). Methods CT, conventional MRI, dynamic MRI, and pathological data of 16 patients with SBPA were analyzed. The manifestations of both CT and conventional MRI, the dynamic time-signal curve, time of peak enhancement, and average enhancement rate were compared between SBPA in the 16 patients and chordoma of the skull base (CSB) in another 9 patients. Results The CT appearances of both tumors were quite similar, offering no differential value. Both tumors were slightly hypointense on T 1 weighted images, but SBPA was mildly hyperintense and CSB was markedly hyperintense on T 2 weighted images. The T 2 weighted signal intensity between both tumors differed significantly (P5 min, (40?5) /min for CSB, respectively (P

Objective To introduce the technical key points and clinical efficacy of dual plane breast augmentation under endoscope through a transaxillary incision.Methods By analyzing the 89 surgical cases,we have summarized the key points of the pre-operative design,surgical skills and postoperative management.Results All patients had no uncontrolled bleeding during operation and loss of nipple and areola sensation.71 patients got 6-12 months follow-up,showing that only one case presented with unilateral capsular contraction,and the others had satisfied results.Conclusions Blunt dissection can reduce the risks of uncontrolled bleeding on the inner side of the pocket and the damage of the nerves on the lateral side of the dissecting pocket.The lower inner part,lower part and lower lateral part are the areas that could be sharply dissected by electrocautery under endoscope to achieve the dual plane Ⅰ.The drainage and bandage are necessary after the operation.
