Objective: To observe the effect of superior technology using three dimension radiation treatment plans (3D-RTPS) in the reduction of postradiation xerostomia in patients with head and neck cancer. Methods: 3D-RTPS of conventional radiation and new superior technique were applied in the patients of 3 kinds of head and neck cancer (tumor in middle, lateral, between middle and lateral area of head and neck). Superior technology including superior ray entrance, multi fields, conformal irradiation and application of wedges. Analysis of 3D dose distributions and dose volume histograms (DVH) was used to evaluate the dose and volume in tumor, parotids and spinal cord in the patients. Tumor dose of 55.6～68.6 Gy (average 58.8 Gy) was given to the patients in conventional radiation group in 8 patients, 53.5～68.5 Gy (average 58.3 Gy) to new radiation technique group in 12 patients. Whole saliva flow rate and subjective xerostomia scores were assessed in patients during radiation course and follow-up. Results: The dose in contralateral parotids in patients with tumor in lateral area, between lateral and middle area in conventional radiation and new radiation technique groups were 51.8～64.3 Gy and 0.4～1.4 Gy, respectively. The dose in parotids in patients with tumor in middle area in conventional radiation and new radiation technique groups were 51.8 and 24.7 Gy respectively. The rate of xerostomia at the end of radiotherapy and in 4～6 months follow-up after radiotherapy in patients of new radiation technique group were 8.3 % (1/12) and 0 respectively. Those in patients in conventional radiation group were 87.5 % (7/8) and 50 % (4/8) respectively. Conclusion: Superior technology using 3D-RTPS can reduce the rate of postradiation xerostomia in patients with head and neck cancer.

Objective:To compare the effect of intraoral and extraoral approach for the sugical treatment of mandibular cysts in the angle and ramus. Methods:Cysts in the mandibular angle and ramus were treated by intraoral approach in 57 cases and extraoral in 18 cases. The following data were collected: operation time, peroperative blood loss, postoperative infection, mouth opening, recurrence rate, injury of the submandibular branch of the facial nerve and sensory function of the inferior alveolar nerve. The data of the two groups were compared statistically. Results:Average operation time (min) of intraoral and extraoral appoarch was 84.65?5.16 and 122.78?10.84(P0.05). Conclusion:Intraoral approach is effective in the treatment of cyst in mandibular angle and ramus.

0.2).The lymphocyte counts of the KD area grain group and the group of the KD area grain supplemented with Se were lower than that of the non-KD area grain group, and the CIC level and the hepatic Se content were much lower in the group of the KD area grain than in the other groups (p

Mandelic acid(MA). the hydrolysate of a compound extracted from the leaves of prunus Persica B, possesses a strong spermicidal effect in vitro. In this experiment. the International Planned Parenthood Federation screening method for spermicides was used. Dilutions of MA, between 0.8mg/ml and 3.3mg/ml, totally immobilized human spermatozoa in less than 1 min. When the lowest spermicidal concentrotions of MA and boric acid against human spermatozoa were compared, it was found that MA was 40 times more potent than boric acid.

Solid internal pressure is one of the important parameters in traffic bridge and defense field.However, the existing testing equipments have the defects of serious electromagnetic interference, poor reliability, and poor accuracy.To overcome the above problems, a fiber bragg grating (FBG) high pressure solid pressure sensor which used thin plates as elastic bearing diaphragm and applied the deflection under pressure to pull the pressure sensitive grating to realize pressure sensing axial displacement was designed.By calculating on the structure according to the measurement range and finite element simulation, its feasibility was confirmed.In the laboratory with constant temperature, the pressure calibration experiment was carried out, and the temperature compensation was performed by the temperature compensation grating in the same temperature field to correct the temperature drift of strain grating.Experimental results showed that the newly devised FBG pressure sensor could sense the pressure as high as 50 MPa, with a linearity of 99.2%.

OBJECTIVE:To study the effect and its mechanism of dexmedetomidine(Dex)on inflammatory response in septic mice. METHODS:Mice were randomly divided into normal control group,model group,miR-146a inhibitor (50 mg/kg)+Dex (50 μg/kg)group,Dex low-dose,medium-dose,high-dose groups(10,30,50 μg/kg),10 in each group. Except for normal con-trol group,other groups were intraperitoneally injected lipopolysaccharide to induce septic models,intraperitoneally injected rele-vant medicines after 0.5 h. After drug intervention for 6 h,miR-146a expression,IRAK1 and TRAF6 mRNA expressions in periph-eral blood mononuclear cells in each group were detected by real-time fluorescence quantitative polymerase chain reaction method. IRAK1,TRAF6 protein expressions in peripheral blood mononuclear cells in each group were detected by Western blot method. TNF-α,IL-6 levels in serum were detected by enzyme-linked immunosorbent method. RESULTS:Compared with normal control group,miR-146a expression,TNF-α and IL-6 levels,IRAK1,TRAF6 mRNA and protein expressions in peripheral blood mononu-clear cells in model group were increased(P<0.01). Compared with model group,miR-146a expression in peripheral blood mono-nuclear cells in Dex medium-dose,high-dose groups were increased;TNF-α and IL-6 levels,IRAK1,TRAF6 protein expressions were decreased (P<0.05 or P<0.01);while IRAK1,TRAF6 mRNA expressions changed less obviously (P>0.05). Compared with Dex high-dose group,miR-146a expression,in peripheral blood mononuclear cells in miR-146a inhibitor+Dex group was de-creased;TNF-α and IL-6 levels,IRAK1,TRAF6 protein expressions were increased (P<0.05 or P<0.01);while IRAK1, TRAF6 mRNA expressions changed less obviously(P>0.05). CONCLUSIONS:Dex can inhibit the inflammatory response in sep-tic mice. The mechanism may associate with inducing miR-146a expression and inhibiting the 2 important adaptor proteins IRAK1, TRAF6 expressions in Toll-like receptor 4/nuclear factor-κB pathway.
