Objective To investigate the effects of compound lidocaine cream applied to tracheal tube on the recovery of tonsil with adenoidectomy in general anesthesia. Methods 120 patients undergoing elective tonsillectomy with adenoidectomy were randomly divided into the experimental group and the control group. In the experimental group, the surface of the tracheal tube was uniformly coated with compound lidocaine cream before anesthesia. In the control group, paraffin oil was given evenly to the surface of the tracheal tube. The changes of hemodynamics and the incidence of complications in the two groups were observed and recorded. Results The indexes of hemodynamics in the experimental group were more stable than those in the control group, and the control group had poor tube resistance, and the incidence of complications such as cough, irritability and sore throat was increased (P<0.05). Conclusion Application of compound lidocaine cream on tracheal tube surface can effectively reduce the cough and other stress response during the general anesthesia recovery period, decrease postoperative irritability and improve the safety of children after surgery.

All patients were followed up for their symptoms, life quality and surviving times, and were regularly examined by endoscopies and esophageal barium radiography.Results The dysphagia in short term was completely released in 96 4% (187 of 194 patients). The average diameter of stoma was extended significantly from 0 44 cm to 2 36 cm after the therapy ( P

OBJECTIVE The aim of our study was to evaluate the significance of the frequency of microsatellite instability (MSI) and its relationship to mismatch repair gene (MMR) in laryngeal squamous cell carcinoma.METHODS We investigated the expression frequency and clinical significance of MSI and MMR in 50 laryngeal squamous cell carcinoma (LSCC) patients from Beijing Tongren Hospital. The status of MSI was evaluated using microdissection - polymerase chain reaction (PCR) - single strand length polymorphism (SSLP) - silver staining.Five markers on chromosomes 1p, 3p, 5q, 9p, 17p, which were adjacent to BCAR3 (breast cancer anti-estrogen resistance 3), FHIT, APC, CDKN2A (p16), TP53 respectively, were used. Two of the six components of MMR -hMLH1 and hMSH2- were investigated by an immunohistochemical approach because of the high frequency of their downregulation in head and neck tumors. RESULTS The informative case number of the five markers (D17S796, D3S3544, D5S656, D1S375, D9S162) were 44, 42, 45, 44 and 40 respectively. The incidence of MSI was lower than the frequency of loss of heterozygosity (LOH). The incidence of MSI on D17S796 (TP53)was 20.5% (9/44),on D3S3544 (FHIT) was 14.3 % (6/42), on D5S656 (APC) was 31.1% (14/45), on D1S375 (BCAR3) was 20.5 % (9/44), and on D9S162 (CDKN2A) was 15.0 % (6/40). Though there was no relationship between MSI status and age, gender, smoke history, tumor location, tumor differentiation and T stage (P＞0.05),there was a strong correlation between MSI and relapse condition (P＜0.01). Also, MSI status correlated with MMR expression to some degree (P＜0.01), but it was common for negative and positive staining of MMR to coexist on the same slide. CONCLUSION Microsatellite instability and abnormal mismatch repair may contribute to the carcinogenesis of a subset of laryngeal squamous cell carcinoma. Microsatellite instability may be a characteristic signal of tumor recurrence.

0.05).⑥ The incidence of MSI at D3S1234,D3S4103,D3S1300 in recurring cases was 83.33 %,but the ratio of MSI inprimary cases was 30.77 %,the former was remarkablyhigher than the latter(P=0.004).CONCLUSION ①Microsatellite analysis showed that both LOH andMSI of FHIT gene existed in laryngeal carcinoma andhypopharyngeal carcinoma,the former was morecommon.② FHIT gene participates the developmenof laryngeal carcinoma and hypopharyngeal carcinoma and may be one of the candidate tumor suppressor genes.③ MSI of FHIT gene may be correlated with recurrence of laryngeal and hypopharyngeal carcinoma.

Objective:To investigate the effect of MT01 on the differentiation of osteoblasts under infected condition through determining the expression level of collagen Ⅰ (Col Ⅰ )mRNA in MG63 cells treated with Porphyromonas gingivalis (Pg).Methods:The cultured MG63 cells were divided into blank control,MT01,Pg, and MT01+Pg groups.MT01 at a concentration of 1 mg·L-1 was added into the MG63 cells,and the cells were incubated for 3 h.The cells treated with PBS (1 mg·L-1 )were used as control group.Then Pg (MOI=100∶1) was added.Real-time PCR was used to detect the expression levels of ColⅠ mRNA in MG63 cells at 2,4,6,8, 12 and 24 h after incubation.Results:Compared with blank control group,the levles of ColⅠ mRNA in the MG63 cells in MT01 and MT01 + Pg groups had no significant changes at 2 and 4 h (P > 0.05);the Col Ⅰ mRNA expression levels in MT01 group at 8,12 and 24 h were increased (P < 0.05 or P < 0.01).Compared with Pg group,the expression levels of ColⅠ mRNA in MT01+ Pg at 2 and 4 h were decreased,but the expression levels of ColⅠ mRNA were increased at 6,8,12 and 24 h (P <0.05 or P <0.01).Conclusion:MT01 can up-regulate the expression level of Col Ⅰ mRNA in the infected MG63 cells; MT01 could promot the differentiation of osteoblasts under infected condition.

Objective To investigate the infection status of HIV/AIDS patients complicated with pneumocystis Carinii Poneumonia(PCP),and the role of CD4+ T lymphocyte in PCP.Methods PC was detected by Giemsa's staining and CD4+ T lymphocyte was counted by flow cytometry.Meanwhile,this text calculated and compared a series of indexes about PC infection,such as the total positive rate,the average annual positive rate,the average monthly positive rate,the positive rate between female and male,the positive rate between sputum and BALF specimens,and the relationship between the positive rate and CD4+ T lymphocyte count.Results The total positive rate about PC infection of the 1 806 eases of sputum specimens was 46.8％,and the incidence mainly from April to July during a year,and the positive rates were 46.3％ and 50.2％ for males and females respectively.The results showed that there were no significant differences when compared with the average annual positive rate ( P ＞ 0.05 ),but there were significant differences when compared with the average monthly positive rate ( P ＜ 0.05 ),the positive rate between female and male(P＞0.05),and among 3 formerly defined ranges of CD4+count(P ＜0.05).Conclusion Giemsa's staining showed the total positive rate was 46.8％ of the HIV/AIDS patients infected by PC with sputum specimens,which represented a seasonal fluctuation tendency.The positive rate of BALF was higher than that in sputum,and it increased with CD4+ count decreasing.Giemsa's staining was an efficient,simple and feasible way for PC detection and easy for generalization.Meanwhile,it is strongly relied on the operator's experience and skill.
