OBJECTIVE: Tonsillectomy is one of the most frequently applied operations in the ENT practice. This prospective study compared intraoperative records and postoperative clinical outcomes between adults and children patients following monopolar electrocautery tonsillectomy. METHOD: Forty adult patients and Forty children patients with histories of recurrent tonsillitis or hypertrophic tonsillitis were enrolled. Intraoperative parameters and postoperative outcomes were compared. RESULT: Children tonsillectomy with monopolar electrocautery was significantly faster to perform (P < 0.05), and produced significantly less intraoperative blood loss (P < 0.05), and faster to return to commencement of a regular diet (P < 0.05) than adults. Children tonsillectomy endured less postopera- tive pain within a week (P > 0.05) than adults, but there was no significant difference in pain on the 14th postoperative day in two groups. There was no obvious postoperative hemorrhage in two groups. There was no significant difference in postoperative tonsillar fossa healing and postoperative temperature between the groups. CONCLUSION Children and adults tonsillectomy with monopolar electrocautery had clinical characteristics respectively. Monopolar electrocautery tonsillectomy was safe and operated easily in both two groups.

This study examined the effect of astilbin on the proliferation of rat aortic smooth muscle cells (RASMCs) induced by angiotensin II (AngII) and explored the possible mechanisms. Cell proliferation model of RASMCs was induced by treatmente with AngII. Cells were randomly divided to 8 groups. Normally cultured VSMCs serves as blank control group; in AngII model group, cells were treated with AngII at 10(-7) mol/L; in three astilbin groups, cells were treated with 10, 15, 30 mg/L of astilbin; in three AngII+astilbin groups, cells were treated with AngII (at 10(-7) mol/L) and astilbin at 10, 15, 30 mg/L. Cell proliferation ability was detected by MTT method and the cell cycles and proliferation index were flow cytometrically determined. The expression of c-myc mRNA was assessed by using reverse transcription polymerase chain reaction (RT-PCR), and the expression of NF-κB in RASMCs was immunocytochemically observed. Our results showed that MTT metabolism in RASMCs in the basic and AngII stimulated situation was inhibited by astilbin, and the cells numbers of G(0)/G(1) phase were increased and that of G(2)/S phase were decreased markedly. Not only highly expression of c-myc gene stimulated by AngII could be inhibited by Astilbin significantly, but also the expression of NF-κB protein can be down regulated by Astilbin. We are led to conclude that astilbin astilbin can inhibit the AngII-mediated proliferation of RASMCs by blocking the transition of RASMCs from G(0)/G(1) phase to S phase and by down-regulating the expression of NF-κB, c-myc gene.

Objective:To investigate the expression of Survivin and it's relationship with the expression of Bcl-2 in sinonasal inverted papilloma (SNIP).Method:Immunohistochemical method was used to determine the expression of Survivin and Bcl-2 in 30 cases of SNIP,10 cases of sinonasal squamous cell carcinoma(SCC) and 10 cases of normal inferior concha tissues.Result:Survivin was expressed in 22 of 30(73.3%)cases of SNIP,8 of 10(80.0%)cases of SCC and not expressed in 10(0%)cases of normal inferior concha tissues.Expression of Survivin was significantly higher in SNIP and SCC than in normal tissues.Bcl-2 was expressed in 9 of 10(90.0%)cases of SCC and 2 of 10(20.0%)cases of normal inferior concha tissues.Expression of Bcl-2 was significantly higher in SCC than in normal tissues.Bcl-2 was expressed in 14 of 30(46.7%)cases of SNIP,higher than normal tissues.Expression of Bcl-2 was positively related to expression of Survivin.Conclusion:Survivin may play an important role in the pathway of progression of SNIP and SCC.It may be identified as a new therapeutic target.Bcl-2 may play a synergic role with Survivin in progression of SNIP.

ObjectiveTo evaluate the efficacy and safety of domestic taerolimus in the manage-ment of acute rejection in renal transplantation reeipienta.MethodsA multieeneter, open and com-parative study for domestic Taerolimua and Prograf was performed. Eighty reeipienta of first allogenie renal transplantation were randomized into 2 groups: ①Experimental group (accepting Fumeixin ad-ministration, n=58) included 23 males and 35 females with the mean age of(39.1±9.6)years. ②Control group(accepting Prograf administration, n=22) included 12 males and 10 females with the mean age of(41.34±8.5)years. There was no significant difference in the volume, warm and cold is-chemia time of donor renal, age and sex of donor. All of the 80 cases accepted tacrolimus (domestic or foreign made, at the dose of 0. 10～0. 15 mg·kg-1·d-1 , q 12 h) treatment that combined with MMF and prednisone posttransplantation. Tacrolimus CO was aimed to 8-12 ng/ml in the first 60 days and 5-10 ng/ml later. The dose of MMF was according to the rule of each transplantation center based on the following recommendation: 1.5-2.0 g/d for the weight above 70 kg, 1.5 g/d for the weight 50-69 kg, and 1.0 g/d for the weight below 49 kg, in two divided doses. Prednisone was ad- ministrated as per ruler of each center. ResultsObservation termination was 3 months. Morbility of actue rejection was 3.40% (2/58)and 13.6% (3/22) in experimental and control group(P>0.05). Ad-verse events including hypertension, hyperlipemia, hyperglycemia and slight abnormality of liver func-tion occurred in 36. 2%(21/58) and 36. 4% (8/22) cases of experimental and control group(P> 0. 05). The survival rate in the 2 groups was 100%. The dose of tacrolimus in experimental group was significantly lower than that in the control group at 8 and 12 weeks posttransplant, while drug valley concentration in serum was proximal in 2 groups during the whole observation period.Conclusion Domestic tacrolimus capsules can be used effectively and safely in the management of acute rejection in renal transplantation.

Objective To assess the efficiency and safety of mycophenolate mofetil (MMF) in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO). Methods Twenty-seven patients with MS or NMO were selected, and the patients were divided into 2 groups:MMF group (MMF combined with glucocorticoid treatment group, 10 cases) and glucocorticoid group (only glucocorticoid treatment group, 17 cases). There were 5 cases with MS and 5 cases with NMO in MMF group. There were 13 cases with MS and 4 cases with NMO in glucocorticoid group. The therapeutic efficacy 6 months after treatment, expanded disability status scale (EDSS) before treatment and 6 months after treatment, and annualized relapse rate (ARR) were compared; and the safety was observed. Results There was no statistical difference in efficacy rate 6 months after treatment between MMF group and glucocorticoid group: 9/10 vs. 11/17, P>0.05. The EDSS scores 6 months after treatment in MMF group and glucocorticoid group were significantly lower than those before treatment: (2.41 ± 2.05) scores vs. (3.40 ± 2.05) scores and (1.17 ± 0.92) scores vs. (2.38 ± 1.28) scores, and there were statistical differences (P<0.05), particularly for the patients with MS. The ARR 6 months after treatment in MMF group was significantly lower than that before treatment: 0 time/year vs. 0.75 times/year, and there was statistical difference (P<0.05). The difference of ARR before and after treatment in MMF group was significantly higher than that in glucocorticoid group: 0.75 times/year vs.- 0.46 times/year, and there was statistical difference (P<0.01), particularly for the patients with MS. Only 1 female patient had myalgia when taking higher dosage of MMF, and the symptom tended to relieve after the dosage was reduced. Conclusions MMF is effective in the treatment of MS and NMO. MS can improve the neurological function and reduce the recurrence of the disease;and the safety is high.

A set of primers amplified the VP1 gene of foot-and-mouth disease vims (FMDV) was designed and synthesized. A reverse transcription-polymerase chain reaction (RT-PCR) technique detected the RNA of FMDV was established after selecting the best purification method, reagents and reaction conditions. Samples of fresh milk, lymph node, spinal cord, vesicular skin, milk powder, cotton swab, mouse and meat in daughter-house were detected by RT-PCR, positive rates were41.4% (24/58), 13.33% (2/15), 20% (1/5), 100% (1/1), 100% (1/1), 37.5% (12/32), 100% (2/2) and 10% - 70%, respectively. However, positive rate of cockroach detected by RT-PCR was 0. The results showed that the established FMDV RT-PCR technique provided a more sensitive, specific and reliable method for diagnosis and epizootic study of the foot-and-mouth disease.

Cold injury is very damaging. This article summarizes the mechanism, types, and rehabilitation of cold injury, focusing on the degree and clinical treatment of frostbite. Frostbite can mainly cause damage of microcirculation and capillary structure, while burn injury can mainly cause damage of cutaneous tissues. Based on this, the key point of management of frostbite is to improve microcirculation and appropriate rewarming, while that of burn injury is wound repair. Up to date, the rate of amputation caused by frostbite is still high, and the rehabilitation for sequela caused by frostbite remains a big challenge in modern medicine. It is worth paying more attention to.
