Objective: To investigate the mechanism of Mycobacterium tuberculosis invasion to mouse dendritic cells ( DC ) .Methods: Mycobacterium tuberculosis strain H37Rv was co-cultured with mouse DC2.4 cells.The mRNA expression of Toll-like receptor 2/4(TLR2/4) in DC2.4 cells was detected by fluorescent quantitative real-time PCR and the protein expression of nuclear factor κB ( NF-κB ) was assessed by Western blotting .The extracellular concentration of tumor necrosis factor α( TNF-α) was measured by ELISA methods during Mycobacterium Tuberculosis invasion .Indirect immunofluorescent staining and flow cytometry assay were used to detect the expression of CD80 and CD86 on DC2 .4 cells before and after invasion .Results:The invasion of Mycobacterium tuberculosis in DC2.4 cells was observed after 2 h of co-incubation.The rates of invasion were (37.9 ±5.6)%,(51.2 ±7.6)%,(57.2 ±8.9)%and(63.9 ± 6.8)% at 6,8,10 and 12 h after co-incubation,respectively.The mRNA expression level of TLR2 /4 was significantly increased at 6 h but decreased at 10 h after co-incubation.The expressions of NF-κB p65 and TNF-αwere higher in DC2.4 cells after being invaded by 6 , 8 , and 10 h and then gradually decreased .CD80 and CD86 expression were increased on DC 2 .4 at 6 h after co-incubation .Conclusion:Invasion of Mycobacterium tuberculosis strain H37 Rv to DC might enhance its antigen-presenting function through activation of TLR 2/4-NF-kB signaling pathway .

OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.

OBJECTIVETo investigate the effect of histone deacetylase inhibitor suberic bishydroxamate (SBHA) on human acute myeloid leukemia (AML) cell lines.

METHODSAML U937, KG-1 and Kasumi-1 cells were treated with SBHA. Cell growth was measured by MTT assay. Apoptosis was determined using flow cytometry. Activation of Caspase pathway and expression of apoptosis regulator proteins were detected by Western blot.

RESULTSSBHA significantly induced growth arrest and apoptosis in U937, KG-1 and Kasumi-1 cells. Enhanced apoptosis was observed in SHBA group evidenced by strong activation of Caspase-9, Caspase-8 and Caspase-3. SHBA treatment resulted in down-regulation of anti-apoptotic protein Bcl-2 and Bcl-xl expression; down-regulated expression of antiapoptotic proteins survivin, XIAP and cIAP was also detected after SBHA treatment.

CONCLUSIONSBHA can effectively kill AML cells by inhibiting cell growth and inducing apoptosis, which is associated with the activation of Caspase pathway and regulation of apoptotic related proteins.

To investigate and summarize the characteristics of mass media reports about medical disputs, and to analyze how the reports impact public perception and behaviors, and finally to propose some suggestions. A total of 385 people were conveniently randomizedly sampled to the survey, including 280 citizens in Beijing and 105 netizens. The results showed reporting modes by the mass media were diversified, and their truthfulness was various. Among them, 63.56% people thought the mass media reporting “medical disputs” almost supported the truthfulness, while 23.29% thought the mass media lacked truthfulness, because the format of the mass media reporting was fast speed rather than good quality. A total of 98.63% people thought the mass media has an impact on the public perception and behaviours, where 69.36% supported their positive aspects, while 30.64% showed negative. Based on the views above, it’s found that the mass media lacked right information of medicine. Therefore, in order to make a harmonious condition of doctor-patient relationship, it’s necessary to truly report the news with a scientific view, to build a platform for the information exchanges between hospitals and media, and to strengthen the social supervision and management.
