OBJECTIVEThis study is performed to investigate the cell topographies and biomechanical properties of two different types of temporomandibular joint (TMJ) discs from goats by using JPK Nano Wizard 3 biological atomic force microscopy (AFM). This process provides a guideline for selecting seed cells for TMJ disc tissue engineering.

METHODSTMJ disc cells from primary goats were cultured by monolayer culture method. AFM was used to contact scan the topographies of the two types of TMJ disc cells under physiological environment. Approximately 20 chondrocyte-like and fibroblast-like cells were selected randomly to plot the force-versus-distance curves of the cytoplasm and nucleus. Young's modulus and adhesion were analyzed by JPK Data Processing.

RESULTSThe triangle-shapednucleus of the chondrocyte-like cell occupied a large portion of the cell. Cytoskeleton was arranged dendritically on the surface. Pseudopodia were extended from cell edges. The spindle-shaped nucleus of the fibroblast-like cell occupied a significantly larger region compared with the cytoplasmic region. Cytoskeleton was arranged regularly. Cell edges were smooth with less pseudopodia extended. No difference was found in the surface roughness between the two types of cells. According to the force-versus-distance curves, the Young's moduli of the two types of cells were not statistically different (P>0.05), but differences were found in the cytoplasmic regions (P=0.047). No statistical difference was found in the adhesions between the two types of cells (P>0.05).

CONCLUSIONThe AFM topography and curves were compared and analyzed. The two types of TMJ disc cells exhibited significantly different topographies, but only slight difference in their mechanical abilities.

Objective To explore the value of serum microRNA-155-5p and -133a-3p (miR-155-5p and miR-133a-3p) expression for the diagnosis and prognosis evaluation of sepsis. Methods A prospective observational study was conducted. 105 sepsis patients admitted to emergency intensive care unit (EICU) of the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2016 were enrolled. They were divided into three groups according to the severity: 35 patients with sepsis, 35 with severe sepsis, and 35 with septic shock. At the same time, 35 healthy persons were selected as the control group. According to the prognosis, the patients were divided into improved group (n = 70) and in-hospital death group (n = 35). The clinical data of all the subjects were collected. The mRNA expressions of miR-155-5p and miR-133a-3p were determined by reverse transcription-polymerase chain reaction (RT-PCR). The receiver-operating characteristic curve (ROC) was plotted to evaluate their clinical value for the diagnosis and prognosis of sepsis. The binary logistic regression was used to analyze the risk factors affecting the prognosis of sepsis patients. Results ① The mRNA expressions of serum miR-155-5p and miR-133a-3p were gradually increased with the aggravation of sepsis. The mRNA expression of miR-155-5p (2-ΔCt) in sepsis, severe sepsis, sepsis shock groups was 1.89±0.48, 2.21±0.41, 2.79±0.73 (F = 23.737, P = 0.000), and the mRNA expression of miR-133a-3p (2-ΔCt) was 1.38±0.31, 1.74±0.65, 2.08±0.47, respectively (F = 27.710, P = 0.000). It was shown by ROC curve analysis that the area under the ROC curve (AUC) of serum miR-155-5p and miR-133a-3p for the diagnosis of sepsis was 0.855 [95% confidence interval (95%CI) = 0.761-0.949] and 0.769 (95%CI = 0.666-0.872) respectively. The cut-off value of miR-155-5p for the diagnosis of sepsis was 1.64, the sensitivity was 85.3%, and specificity was 80.6%. While the cut-off value of miR-133a-3p was 0.82, the sensitivity and specificity were 97.9% and 54.8% respectively. ② Compared with improved group, the patients of in-hospital death group were more serious, and procalcitonin (PCT), C-reactive protein (CRP), D-dimer, lactic acid (Lac), sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, and the mRNA expressions of miR-155-5p and miR-133a-3p were significantly increased (all P < 0.05). While there was no statistically significant difference in gender, age, white blood cells (WBC), serum creatinine (SCr) between the two groups (all P > 0.05). It was shown by binary logistic regression analysis that Lac [odds ratio (OR) = 0.514, 95%CI = 0.260-0.893, P = 0.024], sepsis severity (OR = 0.039, 95%CI = 0.023-2.955, P = 0.016), SOFA score (OR = 0.668, 95%CI = 0.474-0.825, P = 0.001), serum miR-155-5p expression (OR = 0.117, 95%CI = 0.020-0.530, P = 0.007) were the risk factors affecting the prognosis of patients with sepsis. Conclusions The expression of serum miR-155-5p and miR-133a-3p may be used as specific indicators for the diagnosis of sepsis. And the expression of miR-155-5p can be used as independent impact factor for the estimation of sepsis prognosis.

Aim To investigate the protective effect of cinnamic aldehyde ( CA ) on hormone-induced osteo-clasts proliferation and bone resorption in vitro and its molecular mechanisms. Methods RAW264. 7 cells induced into osteoclast were treated with RANKL and M-CSF and then were divided into control group, dexa-methasone ( DEX ) group and different doses of CA (11. 6, 23. 2, 46. 4 μg·L-1 ) groups. OCs were ob-served after tartrate resistant acid phosphatase( TRAP) staining. The cell proliferation was determined by MTT assay at different time points. The expression levels of TRACP5 b in cell cultured supernatants were measured by ELISA. RT-PCR technique was applied to examine the transcriptional levels of RANK and NFATc1 . Re-sults In MTT assay, the proliferation of osteoclasts stimulated by dexamethasone was promoted seriously compared with negative control group ( P < 0. 05 ) . Meanwhile, DEX could strengthen the content of TRACP5 b and up-regulate the expressions of RANK and NFATc1 mRNA. After administration of CA, the proliferation was inhibited, while the enhanced expres-sion of TRAP5b was reversed,and the over-expressions of RANK and NFATc1 mRNA were obviously down-regulated in a time-and-dose-dependent manner ( P <0. 05 ) . Conclusion The results suggest that CA in-hibits proliferation and bone resorption of osteoclast in-duced by DEX, which may be mediated by down-regu-lation of RANK and NFATc1 mRNA.

Steam distillation was used to extract essential oil in the Rhizome Atractylodes. Infrared spectroscopy and gas chromatography were used in the qualitative and quantitative analysis on constituents of essential oil of processing products of Rhizome Atractylodes. Thermogravimetric analysis was used in the comparison of pyrolysis characteristics between Rhizome Atractylodes and its excipients. The results showed that the content of essential oil was declined after processing. However, after being processed, the content of atractylodin was increased at different degrees compared to crude product. The change of atractylodin showed differ-ent tendency in different processing drugs. The atractylodin content from high to low was in the order of products stir-baked to yellowish, products roasted by bran, products prepared with rice water, crude drug. At the temperature of more than 220oC, excipients had major impact for the pyrolysis characteristics of Rhizome Atractylodes. It was concluded that the essential oil declined, but atractylodin increased after Rhizome Atractylodes being processed. It also provided experimental basis for further research on processing technology, ormulation of quality standard and improvement of processing mechanism.
