The electromyography of the superior and inferior heads of lateral pterygoid muscle of 15 human subjects were recorded. It has been observed that marked active potential occurred in the superior head of the ipsilateral pterygoid muscle and the inferior head of the contralateral muscle during a one-side molar bite. Marked active Potential appeared in the superior head of the lateral pterygoid muscle during the closing movement of the jaw, whereas it appeared in the inferior head during the opening movement.It has not been confirmed that the lateral pterygoid muscle is an important protractor of the mandible, as only relatively weak active potential was recorded in the two heads of the muscles on both sides during the protraction of the jaw. Very marked active potential has been observed in the ipsilateral prenygoid muscle during the lateral movement of the mandible, while in the contralatenal superior head it occurred only slightly. The. above finding does not correspond to the descriptions found in current text-books.The two heads of the lateral pterygoid can therefonose considered as two functionally and structurally distinct muscles.

Therefore this review aims to summarize the meaning, applications, status and influence factors, measurements and training of clinical situation awareness, to provide evidence for training and improving clinical situation awareness.

Objective To analyze the expression and clinical significance of tumor suppressor phosphatase -tension protein gene(PTEN)in differentiated thyroid carcinoma and the relationship with the V600E gene site muta-tion of murine sarcoma viral oncogene homolog B1(BRAF).Methods The expression of PTEN was assayed by im-munohistochemical staining in differentiated thyroid carcinoma and adjacent tissues.The differences were compared between clinical pathological features.The BRAF V600E gene mutation was detected by fluorescence quantitative pol-ymerase chain reaction(PCR)and to investigate the correlation between the expression of PTEN and BRAF V600E mutation.Results The negative rate of PTEN was 78.75%(63 /80)in differentiated thyroid carcinoma,13.75%(11 /80)in adjacent tissues(χ2 =27.236,P =0.000).There were significant differences in the expression of PTEN between I -II and III -IV in TNMstage,grade I and II,and lymph node metastasis(χ2 =10.395,6.948,9.263,P =0.000,0.006,0.000).The differences were not significant in the expression of PTEN between different gender,≤45 years and >45 years different pathological types and tumor diameter <2cm and ≥2cm(χ2 =1.113,0.941, 2.301,1.567,P =0.185,0.213,0.087,0.181).There was correlation between the expression of PTEN and BRAF V600E mutations(r =0.301,P =0.004).Conclusion The expression of PTEN is involved in the occurrence and development of differentiated thyroid cancer and is associated with BRAF V600E.The PTEN has the predictive value of prognosis in tumors.

Objective To assess the diagnostic value of anti-mutated citrullinated vimentin antibodies (anti-MCV) for rheumatoid arthritis (RA), and compare it with anti-cyclic citrullinated peptide antibodies (anti-CCP), rheumatoid factors (RF). Methods Commercially available enzyme-linked immunosorbent assay (ELISA) kit was used to detect anti-MCV antibodies in a group of 177 RA patients, 46 patients with other rheumatic diseases, and 48 healthy blood donors. At the same time, anti-CCP, RF were detected. T test and χ2 test were selected. Results The average concentration of anti-MCV was (523±376) U/ml in RA, (96± 55) U/ml in patients with other rheumatic diseases, (34±18) U/ml in healthy controls. Different threshold levels (20, 40, 60, 80, 100, 120, 140 U/ml) for positive results were calculated bythe areas under the ROC curve (the areas were 0.521, 0.706, 0.769, 0.791, 0.816, 0.826, 0.822), then the best diagnosis efficacy for RA was determined as more than 120 U/ml. At this level, the sensitivity and the specificity for anti-MCV were 80.1% and 80.9% for RA diagnosis. The positive and negative predictive value were 92% and 67.8%. Comparing with anti-CCP, anti-MCV showed comparable specificity but higher sensitivity. And it's also better than RF apparently. If all 3 antibodies were detected at the same time, or anti-MCV combine with one of them, the sensitivity would increase to 95.7%. In addition, Anti-MCV showed positive in 32 of 67(55.2%) patients with RA whose anti-CCP was negative, meanwhile 31 of 59 (52.5%) patients with RA whose RF was negative. Conclusion RF and anti-CCP are complementary in diagnosing RA. The combination detection of RF and anti-CCP could significantly improve the specificity for the diagnosis of RA.

Objective To study the changes of Th17 cell, regulatory T cell (Treg) and interleukin (IL)-6 in the peripheral blood of patients with systemic lupus erythematosus (SLE) and their relationship with disease activity. Methods Percentage of Th17 and Treg in the peripheral blood of 103 patients with SLE and 28 healthy volunteers were detected by flow cytometry. The concentration of IL-6 in SLE patients and healthy volunteers was detected by cytometric bead array (CBA). The disease activity of SLE was measured by SLEDAI. SLE patients were divided into two groups: stable SLE (SLEDAI≤ 9, n=37) and active SLE (SLEDAI＞9, n= 66). The change of Th17, Treg, IL -6 and their relationship with disease activity were analyzed. Nonparamentric tests, t -test and spearman correlation were used for statistical analysis. Results The percentage of Th17 cells and the concentration of IL-6 in the peripheral blood in patients with SLE was higher than that in normal controls [respectively for (1.2±1.1)%, (35±92) pg/ml and (0.6±0.4)%, (6±3) pg/ml, P＜0.05]. However, the percentage of Treg in patients with SLE was lower than that in normal controls [respectively for (1.6±1.2)%,(2.6±1.8)%, P＜0.05]. The percentage of Th17, Th17/Treg IL-6 level in active SLE patients was higher than those in inactive SLE and those in normal controls (P＜0.05). However, the percentage of Treg in active SLE was lower than that in stable SLE patients and that in normal controls (P＜ 0.05). The percentage of Th17, Th17/Treg and concentration of IL-6 was positively correlated to disease activity(P＜0.05). But the percentage of Treg had negative correlation with the percentage of Th17 and disease activity (P＜0.05). Conclusion Th17, Treg and serum IL-6 in SLE patients are abnormal and they maybe contribute to the pathogenesis of SLE.

BACKGROUND: Revascularization is a challenge for the tissue-engineered bone carrying cells after implanted into human body. Previous studies have found that tanshinol can improve the functions of endothelial progenitor cells and exert vascular protective effects.OBJECTIVE: To prepare the β-calcium phosphate (β-TCP) scaffold with tanshinol coating, and to observe its cytocompatibility.METHODS: The β-TCP scaffolds coated with 10-7, 10-6 and 10-5 mol of tanshinol were constructed by negative pressure absorption method. The distribution of tanshinol coating on the scaffold was observed using scanning electron microscopy,and the inner ingredients were analyzed by infrared spectrum. Human endothelial progenitor cells (hEPCs) were cultured in the extracts of β-TCP and β-TCP scaffolds with 10-7, 10-6, 10-5 mol of tanshinol coatings, respectively. The cell proliferation was detected at 2, 4, 6, 8 and 10 days of culture; the levels of nitric oxide and vascular endothelial growth factor in the supernatants were detected at 1, 7 and 14 days of culture; the lumen formation on the matrigel was observed after 14-day culture. hEPCs were respectively seeded onto the β-TCP and β-TCP scaffolds with different dosages of tanshinol coating,and then the cell growth was observed under scanning electron microscope at 7 days.RESULTS AND CONCLUSION: The tanshinol coating evenly distributed on the inner surface of the pores, and its crystalline structure became dense with dosage increasing. Infrared spectrum analysis revealed no changes in the characteristic absorption peak of tanshinol and TCP in the scaffold. The β-TCP scaffolds with tanshinol coating could promote the proliferation of hEPCs, especially the scaffolds with 10-6 and 10-5 mol tanshinol coating. Compared with the β-TCP scaffold, the scaffolds with 10-6 and 10-5 mol tanshinol coating significantly upregulated the nitric oxide level at 14 days of culture, and significantly increased the level of vascular endothelial growth factor at 7 and 14 days of culture (P <0.05). Although it could be found in all β-TCP scaffolds with tanshinol coating, the lumen formation was the maturest in the scaffold with 10-5 mol tanshinol coating. These results suggest the β-TCP scaffolds with tanshinol coating can promote the proliferation and endothelial differentiation of hEPCs, and hold a good cytocompatibility.
