Comparison of the efficacy and long-term stability of tunnel technique and coronally advanced flap in the treatment of gingival recession: a Meta-analysis / 华西口腔医学杂志

OBJECTIVES@#This study aimed to evaluate the efficacy and long-term stability of tunnel technique (TUN) and coronally advanced flap (CAF) combined with connective tissue graft (CTG) in treating gingival recession.@*METHODS@#Databases including PubMed, Web of Science, Embase, and CNKI were electronically searched to collect randomized controlled trial (RCT) of CAF+CTG compared to TUN+CTG in the treatment of Miller class Ⅰ or Ⅱ gingival recession on September 1, 2022.@*RESULTS@#There were 8 RCTs with 305 patients (454 recession sites) participating. The results of the Meta-analysis revealed that, in terms of mean root coverage (MRC) of main indicators, no significant difference was found between the CAF group and the TUN group in both short- and long-term results, which were [MD: 1.45%, 95%CI (-2.93%, 5.82%), P=0.52] and [MD: -0.70%, 95%CI (-6.41%, 5.00%), P=0.81]. However, the CAF group outperformed the TUN group in the long term [MD: 5.69%, 95%CI (0.87%, 10.50%), P=0.02], and the results of complete root coverage (CRC) analysis were similar to those of MRC. In the short term, the TUN group grew keratinized gingiva significantly faster than the CAF group [MD: -0.38 mm, 95%CI (-0.67 mm, -0.10 mm), P=0.008]. Long-term findings revealed no significant difference between the two groups [MD: -0.26 mm, 95%CI (-0.94 mm, 0.43 mm), P=0.46]. The TUN group's secondary index root coverage esthetic score (RES) was statistically significantly higher than the CAF group's [MD: 0.62, 95%CI (0.28, 0.96), P=0.000 3]. Given that there were few results included in the literature and the heterogeneity was too great, no significant difference was observed in the postoperative VAS pain index score [MD: 0.53, 95%CI (-1.96, 3.03), P=0.68].@*CONCLUSIONS@#This study discovered that both CAF+CTG and TUN+CTG can achieve good root coverage in treating gingival recession, with CAF outperforming TUN and both groups achie-ving good long-term stability. After the operation, the TUN group had a higher RES than the CAF group. Given the limitations of this study, more high-quality studies are needed in the future to demonstrate the efficacy of TUN in gingival retraction surgery.

Advances in molecular targeted therapy of thyroid carcinoma / 临床耳鼻咽喉头颈外科杂志

Thyroid carcinoma is the most common endocrine maligancy, and the worldwide incidence has been rising in recent years. Differentiated thyroid carcinoma is the most common thyroid malignancy, which include thyroid papillary carcinoma and follicular thyroid carcinoma, accounting for about 90 percent of thyroid carcinoma incidence. Currently, surgical treatment, iodine radiotherapy and TSH suppressive therapy are the commonly accepted effective treatments for differentiated thyroid carcinoma, and most patients can be cured. But there are still some patients not sensitive to the general treatments, who have lost the treatment of opportunity. Molecular targeted therapy is an agonistic or suppressive treatment for molecular biology targets of malignant tumor, and currently is a frontier research in the field of malignancy treatment. By retrieving and analyzing the related literature of molecular targeted therapy of thyroid carcinoma through PUBMED in the past 5 years, the article introduced the current status of molecular targeted therapy of thyroid carcinoma.

A survey on AIDS knowledge rate and sexual behavior among men who have sex with men population at sexually transmitted disease clinic / 中南大学学报(医学版)

OBJECTIVE@#To survey on men who have sex with men (MSM) population's sexual behaviors, condom-service condition, HIV related knowledge and other issues among MSM population at sexually transmitted disease (STD) clinics to understand the characteristics of behaviors and offer suggestions for effective health education and behavior intervention.@*METHODS@#From January to December, 2009, we used anonymous questionnaires which involved in their mastery of demographic characteristics, sexual behavior, condom-service condition, HIV related knowledge, and so one, to investigate 200 MSM at 3 STD clinics of comprehensive hospital.@*RESULTS@#The average age of informant was (26.7+/- 8.9) years and 121 individuals (62.6%) had confirmed with STD in recent one year. In the recent 6 months, the average number of homosexual partners was 9.2+/- 4.8 and 102 (52.8%) had heterosexual partners. In the sexual intercourse with homosexual, 123 individuals had anal intercourse (63.7 %) and 117 had oral intercourse (60.6%). In the sexual intercourse with heterosexual, 92 (90.2%) individuals had vaginal intercourse, 37 (36.2%) had anal intercourse, and 59 (57.8%) had oral sex behavior.There were a statistical difference between heterosexual and homosexual sex behaviors (P<0.01). The condom-using frequency had statistic difference in different sexual behaviors(χ²=188.396, P<0.001). There was no linear correlation between HIV related knowledge and condom-using condition in sexual behaviors except the heterosexual anal intercourse.@*CONCLUSION@#High AIDS knowledge mastery rate is found in our survey. The respondents get HIV/AIDS knowledge through various ways actively. There is no obvious relation between the mastery of HIV related knowledge and condom-using frequency. The ratio of non-protected sexual behaviors is high in heterosexuals. How to adopt effective methods for behavior intervention to MSM at STD clinic needs to be further studied.

phVEGF165 gene transfer for prevention of stent restenosis after TIPSS / 中华消化杂志

Objective To test the hypothesis that locally direct gene transfer of human vascular endothelial growth factor(phVEGF) 165 could passivate hepatic venous metallic stents by accelerating endothelialization and augmenting biocompatibility of endovascular stent. Methods The complexes of pAdTrackCMV and lipofectamine was smeared homogeneously to the surface of stent coating with poly-1-lysine. Bare stainless steel stents were used as controls. All stents were implanted into the hepatic right vein by the procedure of transjugular intrahepatic venous stent deployment. Results At the end of 1 week after implantation, the site -specific expression of phVEGF was detected by RT-PCR. Green fluorescence and the expression of phVEGF gene were detected in the transfered stented vessel of the treatment group. These phenomena were not observed in the control group. Scanning electron microscopy revealed that the endothelialization of stent was more pronounced in the treatment group than that in control group. At the end of 8 weeks after implantation, quantitative angiography analysis showed the degree of internal diameter stenosis was less severe in the treatment group compared with the control group. Mean neointima thickness, mean neointima areas and percent cross-sectional area narrowing in treatment group was significantly fewer than that in the control group, respectively. Immunohistochemistry analysis revealed that the proliferation of vascular smooth muscle cells was more active in control group than that in the treatment group. Conclusions Local gene transfer of phVEGF165 can passivate endovascular stents by accelerating stents endothelization and enhancing their biocompatibility in hepatic vein, resulting in reducing thrombus formation and attenuating intimal hyperplasia.
