Objective To analyze the mid- and long-term results after coronary artery bypass graft surgery (CABG), to evaluate the accuracy of multi-detector CT coronary angiography (MDCT) on the graft patency status and to compare the patency for different grafts. Methods One hundred and one cases underwent CABG from June 1992 to March 2008 were followed up by searching the database of MDCT (42 cases) and selective coronary angiography (SCA, 59 cases). The mean following up period was (66.79 ±44.27) months. Three hundreds and 10 grafts including 115 arterial and 195 venous were analyzed.A comparison of the patency rate between the arterial and venous grafts was also carried out. At the mean time, 2 groups were divided according to the paft lesions( patency of not). Uunivariate analysis and Logistic regression analysis were made for statistics. Results At the follow-up of (53.93 ± 36.80) months, the patent rate of LIMA, RA, SV and CV examined by MDCT was 94.7%, 92.0%, 85.9% and 60.0%, respectively. The patent rate for MDCT patients with angina was 83.5%, and 95.2% for angina-free group ( P = 0.046). At the follow-up of (75.95 ±47.09) months, the patent rate of LIMA, RA, SV and CV examined by SCA was 87.1%, 81.0%, 53.6% and 57. 1%, respectively. In SCA patients the patent rate was 62.0% for angina group and 100% for angina-free group ( P = 0.025 ). According to logistic regression analysis, only the postoperative period was statistically related to the graft lesion. Conclusion MDCT could find out the occlusions and obvious stenoses of the grafts after CABG. It might be served as a noninvasive method to evaluate the grafts patency postoperatively. The mid- and long-term patency of arterial grafts is better than venous grafts. Graft lesion is an important factor leading to postoperative recurrent angina pectoris. The severity of the graft lesion has a close relation to the lenth of postoperative period.

Cryptotanshinone (CPT), a lipid soluble active compound in Salvia miltiorrhiza, has a significant inhibitory effect on multiple malignant tumors, e. g. chronic myeloid leukemia (CML) cells and can effectively enhance imatinib's chemotherapeutic effect. However, its functional molecular mechanism remained unclear. In this experiment, the authors conducted a systematic study on the effect of CPT on the imatinib sensitivity and P-glycoprotein (P-gp) expression in CML cells by using CML cells K562 and imatinib persister K562-R. The MTT assays were performed to determine CPT's impact on the inhibitory effect of imatinib. Annexin V-FITC/PI staining analysis was used to detect the changes in the cell apoptosis rate. The active changes in apoptosis regulatory proteins Caspase-3, Caspase-9 and PARP were determined by Western blot. After the cells were pretreated with the gradient concentration of CPT, the expression of P-gp was analyzed by Western blot and flow cytometry. The changes in intracellular concentrations of imatinib were determined by HPLC analysis. The results indicated that the pretreatment with CPT significantly increased the proliferation inhibiting and apoptosis inducing effects of imatinib on K562 and K562-R cells as well as the degradation product expression of pro-apoptotic proteins Caspase-3, Caspase-9 and PARP, with a significant difference with the control group (P < 0.01). However, CPT showed no impact on the P-gp expression in CML cells and the intracellular concentrations of imatinib. In summary, the findings suggested that CPT enhanced the sensitivity of CML cells to imatinib. Its mechanism is not dependent on the inhibition in P-gp expression and the increase in intracellular drug concentration.

Objective:To investigate the clinical feature, diagnosis and treatment of autoimmune pancreatitis(AIP).Methods:Clinical data of 20 AIP patients admitted to the First Affiliated Hospital of University of Science and Technology of China from Jan 2014 to Dec 2019 were retrospectively analyzed.Results:Nineteen patients were diagnosed with type 1 AIP and 1 patient was with type 2 AIP. Fifteen patients were diagnosed by imaging, serology and other organ involvement, and 5 patients were confirmed by postoperative histopathology. Thirteen patients received glucocorticoid therapy. Five patients have not received glucocorticoid therapy after surgery.One patient refused treatment, and 1 patient is currently under clinical observation. Seventeen of the 20 patients were followed up, 11 patients were on glucocorticoid therapy with related clinical symptoms being gradually improved, serum IgG4 decreased and imaging findings improved. Five patients did not relapse after drug withdrawal. Three patients had recurrence of jaundice after drug withdrawal. One patient had recurrence of pancreatic lesions after drug withdrawal. Two patients had recurrence of high serum IgG4 after tapering the doses, these 6 patients were treated with steroid maintenance therapy. One patient died of repeated gastrointestinal bleeding 2 months later, and another 4 surgical patients and 1 patient under clinical observation are in good condition.Conclusions:AIP should be diagnosed in combination with clinical manifestations, serological examination, imaging examination and histopathology, especially focal lesions should be differentiated from pancreatic cancer, so as to avoid missed diagnosis and unnecessary surgical intervention.

BACKGROUND:The main component of cartilage, type Ⅱ col agen gene expression in chondrocyte is positively correlated with SOX9 concentration in a dose-dependent manner.
OBJECTIVE:To observe the variation of SOX9 and type Ⅱ col agen mRNA content at different periods in the differentiation process (osteogenic, chondrogenic, adipogenic induction) of mesenchymal stem cel s, and to explore the correlation of SOX9 expression and type Ⅱ col agen.
METHODS:Bone marrow mesenchymal stem cel s were isolated from 4-week-old Kunming mice, and cultured in vitro to passage 3. The cel phenotype was identified with flow cytometry. Cel s were divided into three groups and subjected to three kinds of induction conditions favorable for adipogenic, chondrogenic and osteogenic differentiation, and each group was observed at three time points. In addition, the non-induced cel s were used as a control group. The total RNA of cel s was extracted at 3, 7, 14 days after induction, and SOX9 and type Ⅱ col agen mRNA was quantified with reverse transcription-polymerase chain reaction. The induced cel s were stained by immunofluorescence to observe the differentiation and perform statistical analysis.
RESULTS AND CONCLUSION:Passage 3 bone marrow mesenchymal stem cel s grew wel , and cel phenotype was confirmed as stem cel s by flow cytometry. The staining results showed that, the cel s differentiated into chondrocytes, adipocytes and osteoblasts. The SOX9 mRNA levels in the induced cel s were the highest in chondrogenic differentiation group, then in osteogenic differentiation group, and the lowest in adipogenic differentiation group. Type Ⅱ col agen mRNA levels in the induced cel s were the highest in chondrogenic differentiation group, then in adipogenic differentiation group, and the lowest in osteogenic differentiation group. SOX9 expression in chondrogenic differentiation group increased at 3 and 7 days, and then decreased at 14 days. While type Ⅱ col agen expression increased at 3, 7, 14 days. SOX9 mRNA levels increased as the osteogenic differentiation, while type Ⅱ col agen expression gradual y decreased. There was no significant difference in the SOX9 mRNA expression between adipogenic differentiation group and control group (P>0.05), while type Ⅱ col agen expression was not regularly changed. Experimental findings suggest that, critical effect of SOX9 in chondrogenic differentiation is better than that in osteogenic and adipogenic differentiation. SOX9 is associated with type Ⅱcol agen, which may alter along with the SOX9 in the early chondrogenic differentiation;SOX9 may play a fine-tuning role in the process of chondrogenic and osteogenic differentiation.
