Objective To quantitatively analyze the coronary artery ostia by three-dimensional trans-esophageal echocardiography (3D-TEE).Methods The full-volume images of aortic root and coronary artery ostia were acquired by 3D-TEE in 95 adult patients.The Philips QLab 3DQ measurement technology was employed to determine three mutually perpendicular planes:(1) The transverse plane cross the bottom of three coronary artery sinus.(2) The sagittal plane perpendicular to sino-tubular junction.(3) The coronal plane perpendicular to the aforementioned two planes .The following relevant parameters were measured and recorded:(1) Length, width, height and area of bilateral coronary artery ostia .(2) The angle between coronary arterial outflow tract and aortic root in sagittal plane .(3) The spatial distribution of coronary artery ostia, aortic root and coronary artert sinus .Results The shape of left coronary artery ostia were more regular (round or oval) than right coronary artery ostia ( teardrop-shape or oval ).Calcification was more frequent in right coronary artery ostia (81/95, 85.26%) than that in left coronary artery ostia. There were statistical differences between left and right coronary artery in the parameters of ostial wide , area and height (t =3.85, 3.86, -4.49, all P<0.01).Most left coronary artery ostia were located inside the sinus (76/95, 80.00%), mainly in the upper third segment (69/95, 72.63%); while more than half of the right coronary artery ostia were found outside the sinus ( 53/95, 55.79%).The difference was statistically significant( χ2 =25.91, P<0.01).Conclusion The quantitative analysis of aortic root and coronary artery ostia based on the full-volume images originated from real-time 3D-TEE is feasible, which is helpful for further clinical research .

Chinese Traditional and Herbal Drugs 2017;48(15):3104-3109
Objective: To evaluate the hepatotoxicity caused by water extract with alcohol precipitating of Toosendan Fructus (TF) and Toosendan Fructus + Corydalis Rhizoma (TF + CR) based on metabolic profiling of fatty acids in mice serum. Methods: A gas chromatography-mass spectrometry method was applied for simultaneous quantification of 15 fatty acids, including both non-esterified and esterified fatty acids, in the serum of control, TF-treated, and TF + CR-treated mice. Meanwhile, the change of fatty acid metabolic profile in liver injured mice was analyzed by principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA). Results: The result of PCA showed that the metabolic profile of serum fatty acids in TF-treated mice significantly deviated from the normal level, and CR with hepatoprotective effect could obviously reverse the deviation. More importantly, the result of PLS-DA illustrated that palmitoleic acid, vaccenic acid, and arachidonic acid had important contribution on the hepatotoxicity induced by TF. Therefore, the three fatty acids were identified as potential biomarkers. Conclusion: Hepatotoxicity caused by TF has a good correlation with the metabolic profiling of fatty acid. The project can provide foundation for further investigation on the evaluation and mechanism of TF-induced hepatotoxicity.

OBJECTIVETo study the effect of Tongluo Xingnao effervescent tablets on learning and memory capacity and expression of Na(+)-K(+)-ATPase in hippocampus of rats with chronic cerebral ischemia-induced learning and memory dysfunction model.
METHODThe 2-VO method was used to establish sd rat model learning and memory dysfunction induced by chronic cerebral ischemia. The 50 rats in the successfully established model were randomly divided into the model control group, the Dihydroergotoxine Mesylate tablets group (0.7 mg x kg(-1), Tongluo Xingnao effervescent tablets high dose (7.56 g x kg(-1)), middle dose (3.78 g x kg(-1)) and low dose (1.59 g x kg(-1)) groups and the sham operation group (n = 10) as the control group. The groups were orally given 10 ml x kg(-1) x d(-1) drugs for consecutively 90 days. On the 86th day, Morris water maze was adopted for them. On the 90th day, a leaning and memory capacity test was held. The brain tissues were fixed with 10% formaldehyde and observed for pathomorphism after routine slide preparation and staining. The expression of hippocampal Na(+)-K(+)-ATPase was detected with immunohistochemistry and image quantitative analysis.
RESULTCompared with the model group, all of Tongluo Xingnao effervescent tablets groups showed significant decrease in the escape latency at the 5th day in the Morris water maze, and notable increase in the frequency of the first quadrant dwell, the frequency passing the escape platform and the frequency entering effective area (p < 0.05). According to the pathomorphological detection, the control group showed a significantly higher pathological score than the sham operation group (p < 0.01), the middle dose group showed a significantly lower pathological score than the model group (p < 0.05). According to the immunohistochemistical detection, the model control group showed a remarkably lower mean OD value of Na(+)-K(+)-ATPase than the sham operation group (p < 0.05), high and middle dose groups showed a significantly higher mean od value than the model control group (p < 0.01).
CONCLUSIONTongluo Xingnao effervescent tablets can improve the learning and memory capacity, reduce pathological changes of hippocampal tissues of rats with chronic cerebral ischemia-induced learning and memory dysfunction model, and promote the expression of Na(+)-K(+)-ATPase in hippocampus.

OBJECTIVEFragile X syndrome (FXS) may be identified by many methods, such as PCR assay and Southern blot. However, each method has its limits or shortcomings. This study explored the reliability of the rapid, convenient and inexpensive hair root fragile X mental retardation protein (FMRP ) assay in the identification of FXS.
METHODSFMRP in hair roots was determined by immunohistochemistry assay in 80 healthy children, in 40 children with mental retardation of unknown etiology and in 12 family members in one pedigree of FXS. FXS was confirmed by 7-deza-dGTP PCR.
RESULTSThere was a high expression of FMRP in hair roots (> or =80%) in healthy children. Two children were confirmed with FXS by 7-deza-dGTP PCR in 40 children with mental retardation of unknown etiology. FMRP expression was 10% and zero respectively in the two children. The other 38 children had FMRP expression of more than 80%. FMRP was not expressed in the two cases of FXS from the pedigree of FXS.
CONCLUSIONSInexpensive, rapid and convenient hair root FMRP assay is reliable for the diagnosis of FXS and may be widely applied for screening and diagnosing FXS in children with mental retardation.

OBJECTIVETo investigate the clinical outcome of modified Blair ankle fusion for ankle arthritis.
METHODSBetween November 2009 and June 2012, 28 patients with ankle arthritis were treated, among whom 11 had obvious foot varus deformity, and 17 were almost normal in appearance. There were 13 males and 15 females with an average age of 49.4 years (range, 23-67 years). The main symptoms included swelling, pain, and a limited range of motion of the ankles. The ankle joints functions were assessed by American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analog scale (VAS) preoperatively and at 1 year follow-up.
RESULTSTwenty-eight patients were followed up for 19.8 months on average (range, 1-2 years). Superficial wound infection occurred in 3 cases, and was cured after debridement; the other incisions healed by first intention without complications. All ankles were fused at 1 year follow-up after operation. The symptom was relieved completely in all patients at last follow-up without complication of implant failure, or nonunion. The postoperative AOFAS ankle and hindfoot score was 83.13±3.76, showing significant difference when compared with the preoperative score (45.38±3.21, P<0.01). VAS was significantly decreased from 8.01±0.63 to 2.31±1.05 at 1 year follow-up (P<0.05).
CONCLUSIONModified Blair ankle fusion has the advantages of high feasiblity, less cost and rigid fixation. It shows high reliability in pain relief and may obtain a good clinical effectiveness.
