Objective To compare the clinical efficacy of low temperature-controlled plasma radio frequency ablation by nasal endoscopy with traditional way in treatment of nasal vestibular cyst. Methods 68 patients with nasal vestibular cyst from January 2010 to January 2016 were selected and randomly divided into control group and observation group, with 34 cases in each group. The control group received traditional way (labiogingival groove approach), while the observation group received low temperature-controlled plasma radio frequency ablation by nasal endoscopy. The operating time, introoperative blood loss, postoperative incision pain, wound healing time and complications were compared between the two groups. Results The operating time, introoperative blood loss, postoperative incision pain,wound healing time of observation group were significantly lower than that in control group (P < 0.05). The complication in observation group was lower than that in control group (P < 0.05). Conclusions The low temperature-controlled plasma radio frequency ablation by nasal endoscopy holds many advantages: less pain, good efficacy, simple manipulation and lower complications. Therefore, it is worthy of promoting clinical application.

Objective To investigate the clinical efficacy of microlaryngoscopy radiofrequency in treatment of patients with tongue base cysts. Methods 42 patients with tongue base cysts from January 2013 to December 2014 were randomly divided into treatment group and control group, the treatment group underwent microlaryngoscopy radiofrequency treatment, the control group underwent direct laryngoscopy under the tongue cystectomy, then the operation time, blood loss and postoperative recurrence rate were observed and recorded, and self-evaluation method using visual analog (VAS) to evaluate the effect of surgery. Results The operative time of treatment group was significantly shorter, and the blood loss was significantly less than the control group, the difference between the two groups was statistically significant (P < 0.01); for 1-year follow-up, six-month recurrence rate in control group was 9.52%, the treatment group had no recurrence cases, the difference was not statistically significant (P > 0.05); 12 months, the recurrence rate was 28.57% in the control group, the treatment group, the recurrence rate was 4.76%, the difference between the two groups was statistically significant (P < 0.05); Preoperative VAS score of the two groups have no significant difference, while after surgery, the VAS scores' difference was statistically significant, even treatment group compared with the control group VAS scores after surgery was statistically significant (P < 0.01). Conclusion Microlaryngoscopy radiofrequency in treatment of tongue base cysts have advantages of significant efficacy, safe and reliable, It's worthy of clinical promoting.

0.05) between two groups.Conclusion Two surgicel porcedures offer smilar results in the surgical treatment of primary spontaneous pneumothorax.Both techniques are equally safe,small traumatic,pain controllable,and there are little postoprerative complications and the relapse rate is very low.

Objective To investigate the preventive effect of fibroblast growth factor on infection after tooth extraction among type 2 diabetes mellitus patients. Methods 76 patients with infection prevention were treated with basic fibroblast growth factor, and 90 patients in the control group(n= 324). The intervention group was treated with basic fibroblast growth factor and treated with recombinant bovine basic fibroblast growth factor gel. The routine treatment group was treated with routine rinsing liquid for disinfection to prevent infection. Follow-up observation of infection after 1 week. Results In the group of basic fibroblast growth factor, the infectious rate was 2.63%, which was not significantly lower than that of the control group. The level of white blood cells in the group treated with basic fibroblast factor was (6.67±1.08)×109/L, which was significantly lower than that of the control group. The CRP level was (90.33±12.95) mg/L, which was significantly lower than that of the control group Group level (P<0.05). The incidence of fibroblast infection was 2.7% in men and 6.38% in control group. Although there was no significant difference between the two groups, the difference in the total WBC count and CRP level between the two groups was significant different (P<0.05). The group which use of basic fibroblast growth factor, the total white blood cell count and CRP level of the infection prevention intervention group were significantly lower than the control group (P<0.05). Similar results were found in women. Conclusion Fibroblast growth factor can be used to prevent postoperative infection, and achieve satisfactory results.

OBJECTIVETo confirm the inhibitory effect of Chinese herbs of acid taste on melanin synthesis.

METHODSActive ingredients of 22 kinds Chinese herbs of acid tastes were extracted by alkali extraction and acid precipitation, alcohol extraction, and water extraction, respectively, which was then dispensed into 25.00, 12.50, and 6.25 g/L suspension. Their effects on activities of tyrosinase were detected using mushroom-tyrosinase-DOPA speed oxidation. Their inhibition rates on activities of tyrosinase were respectively compared with inhibition rates of 1.0, 0.5, and 0.1 mmol/L arbutin.

RESULTSThe 22 kinds Chinese herbs of acid taste included Cornus Officinalis, Crataegus pinnatifida, dark plum fruit, Schisandra Chinensis, Chaenomeles sinensis Koehne, Reynoutria japonica Houtt, Achyranthes Bidentata, Sanguisorba officinalis L., Semen Ziziphi Spinosae, Herba Ecliptae, blueberry, immature bitter orange, submature bitter orange, Prunus mume Var, Hovenia acerba Lindl., Fructus Mori, Pomegranate Rind, white paeony root, Rosa laevigata Michx., Portulaca oleracea L, Terminalia chebula Retz, Rhus chinensis Mill. Their alkaline extractions showed inhibition to activities of tyrosinase to different degrees except Herba Ecliptae. Of them, the highest inhibition rate (88.49% ± 9.98%) was got by dark plum fruit at 25 g/L, while the lowest inhibition rate (11.22% ± 3.36%) was got by immature bitter orange at 6.25 g/L. Their alcohol extractions showed inhibition to activities of tyrosinase to different degrees except Herba Ecliptae. Of them, the highest inhibition rate (75.92% ± 5.57%) was got by Hovenia acerba Lindl. at 25 g/L, while the lowest inhibition rate (9.60% ± 1.15%) was got by submature bitter orange at 6.25 g/L. Their water extractions all had inhibition on activities of tyrosinase. Of them, the highest inhibition rate (54.23% ± 3.56%) was got by Fructus Mori at 25 g/L, while the lowest inhibition rate (10.25% ± 1.83%) was got by Semen Ziziphi Spinosae at 6.25 g/L. Compared with 1 mmol/L arbutin water solution, alkaline extractions of dark plum fruit, Schisandra Chinensis, Rhus chinensis Mill., Rosa laevigata Michx., blueberry, Chaenomeles sinensis Koehne, Portulaca oleracea L, Fructus Mori, Achyranthes Bidentata, Pomegranate Rind; alcohol extractions of dark plum fruit, Rhus chinensis Mill., Pomegranate Rind, Hovenia acerba Lindl., Crataegus pinnatifida, Achyranthes Bidentata; water extractions of Chaenomeles sinensis Koehne, blueberry, and Fructus Mori at 25 g/L got obviously higher inhibition rates (P < 0.05, P < 0.01). Compared with 0.5 mmol/L arbutin water solution, alcohol extraction of Chaenomeles sinensis Koehne and alcohol extraction of dark plum fruit at 12.5 g/L got obviously higher inhibition rates (P < 0.05, P < 0.01).

CONCLUSIONChinese herbs of acid taste could inhibit melanin synthesis, and its mechanism was related to inhibiting activities of tyrosinase.

Objective To study the impact of QseBC on the motility of Salmonella enterica serovar Typhi ( S.Typhi ) . Methods The motility of wild-type ( WT) and null mutants (ΔqseB and ΔqseC) at mid-log phase was investigated by swimming assay.Quantitative RT-PCR was carried out to calculate the transcriptional variation of flhD and qseB among WT,ΔqseB andΔqseC.QseB overexpressing strain was constructed to compare its motility and flhD expression with the wild-type control.Results The result of motility assay showed that the motility of ΔqseB was similar to that of the WT strain , while the motility of ΔqseC was much lower than that of WT .qRT-PCR revealed that compared with WT , the expression of flhD was significantly decreased in ΔqseC while the expression of qseB was increased considerably .The motility of QseB overex-pressing strain was lower .Conclusion The expression of flhD may be regulated by QseBC which has an effect on the motil-ity of S.typhi, and the overexpression of QseB may inhibit the motility .
