Objective To assess the image findings of femoroacetabular impingement (FAI).Methods Image findings of 9 patients with surgically proved femoroacetabular impingement were retrospectively reviewed for characteristic image findings of FAL All 9 patients underwent X-ray examinations and MRI of affected hip, and 1 patient underwent MR arthrography (MRA) additionally. Results X-ray examinations of all 9 patients showed bump at femoral head-neck junction or overcoverage of the acetabula.MRI showed various degrees of injury of anterosuperior labrum in all 9 patients. The injuries were stage Ⅰ A in2 cases, stage Ⅰ B in3, stage ⅡA in2, and stage ⅡB in 2. MRA of the case showed tears of anterosuperior labrum, with contrast media entering into the teared labrum. There were sclerosis and cystic degeneration of subchondral bone of femoral head in 2 cases, and these findings were confirmed as cartilage delamination by surgery. Conclusions MRI can display the injures of labrum and articular cartilage, which is helpful to the early diagnosis of FAI.

Thyroid emergency is a rare but potent ially life-threatening condition if not recognized early and managed properly. It is usually due to a severe exacerbation of a preexisting thyrotoxicosis, which later leads to decompensation in different organ systems. The treatment of thyroid emergency remains challenging even with the armamentarium of modern intensive care technologies, especially in patients with cardiac failure and major organ dysfunction.[1–3] Herein, the authors described a case of thyroid emergency with cardiac arrest (CA) supported by extracorporeal membrane oxygenation (ECMO).

Objective To investigate the cognitive function and psychological mental state of patients with juvenile myoclonic epilepsy (JME), and the related risk factors. Methods From September, 2011 to Febrary, 2014, 21 patients with JME and 18 healthy controls matched with age, sex and educational level were assessed with Montreal Cognitive Assessment (MoCA), and Revised Chinese Wechsler Adult Intel-ligence Scale (WAIS-RC) and Symptom Checklist-90 (SCL-90). The risk factors were analyzed with Logistic regression analysis. Results There was no significant difference in the score of MoCA between two groups (t=―1.544, P=0.131). The scores of verbal intelligence quo-tient (VIQ), performance intelligence quotient (PIQ) and full intelligence quotient (FIQ) in WAIS-RC were significantly lower in the patient group than in the control group (t>4.119, P<0.001). The scores of interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, par-anoid ideation and psychoticism in SCL-90 were significantly higher in the patient group than in the control group (t>2.480, P<0.05). Logis-tic regression analysis showed that VIQ significantly decreased in patients taking valproic acid (B=―3.064, OR=0.047, 95% CI=0.002~0.920, P=0.044). Conclusion VIQ, PIQ and FIQ decreased in patients with JME. Furthermore, different levels of dysfunction were found in interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism. Taking valproic acid was the risk factor of cognitive decline.

Untargeted metabolomics analysis of rhubarb and stewed rhubarb samples shows that the determined samples clearly clustered in to two groups, indicating that the processing procedures caused changes in the composition and/or content of components in rhubarb. Ten components were identified by UHPLC-Q-TOF-MS/MS and references, which intensity declined in rhubarb after processing. Targeted metabolomics analysis of rhubarb and stewed rhubarb samples indicated that aloe-emodin, rhein, emodin and physcion were detected with lower intensity in stewed rhubarb samples than in rhubarb samples. Metabolomics analysis of rhubarb and stewed rhubarb indicated the various components of rhubarb changed after processing.

Objective To investigate the effect of a decoction to nourish qi and invigorate the spleen on mitochondrial respiratory chain enzyme complex activity in cardiomyocytes of rats with spleen qi deficiency syndrome. Methods Rats were randomly divided into normal,model,and treatment groups. The model and treatment groups were treated by diet intervention combined with the limit swim method. The general condition and spleen qi deficiency syndrome were assessed on day 15. After the success of the model,the normal and model groups were treated with a con?ventional feeding method combined with normal saline ,and the treatment group was treated by diet intervention combined with a decoction to nour?ish qi and invigorate the spleen for 9 weeks. The activity of two mitochondrial respiratory chain enzyme complexes was observed. Results The ac?tivity of mitochondrial respiratory chain enzyme complexⅡand complexⅣin the model group was significantly lower than the activity in the nor?mal and treatment groups(P<0.05). The activity levels of complexⅡand complexⅣwere significantly different between the model group and the treatment group(P<0.05). Conclusion Spleen qi deficiency can cause decreased activity of mitochondrial respiratory chain enzyme com?plexes in myocardial cells. The decoction to nourish qi and invigorate the spleen can modulate the activity of myocardial mitochondrial respiratory chain enzyme complexesⅡandⅣ.

Objective: To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA. Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system. Results:The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (allP<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05). Conclusion: Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.

Objective: To investigate the cell growth inhibitory effect and molecular mechanism of bakuchiol against human breast cancer MCF-7 cells. Methods: The growth inhibitory effect of bakuchiol on MCF-7 cells was tested by MTT assay. Flow cytometry was used to investigate the distribution of cell cycle and ROS generation. Fluorescence microscope was used to observe the change of cell nucleus. Western blotting was used to detect the expression of the protein related to cell cycle and MAPK family. The ROS scavenger and inhibitors of MAPK family were introduced to investigate the effect on the growth inhibitory rate and the levels of cell cycle related protein by bakuchiol. Results: Bakuchiol inhibited the cell growth on the MCF-7 cells in dose- and time-dependent manner, which showed stronger effect than that of 5-fluorouracil. Furthermore, bakuchiol induced S-phase arrest in MCF-7 cells via ROS generation. The production of ROS up-regulated p-p53 and p21 expression, and then decreased CDK2 and CyclinA2. The changes of bakuchiol on these proteins could be reversed by the ROS scavenger Trion, indicating that ROS was associated with bakuchiol-induced S-phase arrest. In addition, pretreatment with p38MAPK inhibitor SB203580 decreased bakuchiol-caused ROS generation, suggesting that the production of ROS was dependent on p38MAPK pathway. Conclusion: The proliferation inhibitory effect of bakuchiol on MCF-7 cells is related with S-phase cell cycle arrest, and ROS plays a role in the bakuchiol-induced S-phase arrest.

OBJECTIVETo investigate the genetic polymorphisms of DXS7132, DXS6854, DXS6797, DXS9898, DXS8378 and GATA31E08 short tandem repeats (STRs) loci in Chinese Korean ethnic group of Yanbian, Jilin, and to construct a preliminary database.

METHODSThe allele frequencies of the six STRs loci in Chinese Korean ethnic individuals were analyzed by multiplex polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis (PAGE).

Although gene therapy was regarded as a promising approach for glioma treatment, its therapeutic efficacy was often disappointing because of the lack of efficient drug delivery systems. Mesenchymal stem cells(MSCs) have been reported to have a tropism for brain tumors and thus could be used as delivery vehicles for glioma therapy. Therefore, in this study, we attempted to treat glioma by using MSCs as a vehicle for delivering replication-competent adenovirus. We firstly compared the infectivity of type 3, type 5, and type 35 fiber-modified adenoviruses in MSCs. We also determined suitable adenovirus titer in vitro and then used this titer to analyze the ability of MSCs to deliver replication-competent adenovirus into glioma in vivo. Our results indicated that type 35 fiber-modified adenovirus showed higher infectivity than did naked type 3 or type 5 fiber-modified adenovirus. MSCs carrying replication-competent adenovirus significantly inhibited tumor growth in vivo compared with other control groups. In conclusion, MSCs are an effective vehicle that can successfully transport replication-competent adenovirus into glioma, making it a potential therapeutic strategy for treating malignant glioma.
