[Study on the relationship between adenoid and tonsil hypertrophy and obesity in children]

Objective: To study the relationship between adenoid hypertrophy, tonsillar hypertrophy and overweight or even obesity in children. Methods: A total of 799 children aged 2 to 12 years with tonsillar and adenoid hypertrophy from January 2015 to December 2019 in the Department of Otolaryngology Head Neck Surgery, the Sixth Medical Center of Chinese PLA General Hospital were selected. The body mass index (BMI) was calculated according to the height and weight measured routinely at the time of admission. The difference of BMI between children and normal children of the same age, and the correlation between adenoid, tonsil hypertrophy and obesity were compared. Chi-square test was used to compare the surgical children's BMI of different genders with normal children of the same age, and Spearman rank correlation was used to analyze the correlation between BMI and adenoid and tonsil hypertrophy. Results: The Spearman correlation coefficient between tonsil hypertrophy and BMI was 0.078, P=0.077, the Spearman correlation coefficient between adenoid hypertrophy and BMI was -0.058(P=0.100). χ(2) test showed that the proportion of overweight and obesity in school-age children (7~12 years old) was significantly higher than that in preschool children (2~6 years old), and the difference was statistically significant (χ(2)(male)=22.386, P(male)<0.001, χ(2)(female)=4.478, P(female)<0.001). Conclusion: There is no obvious correlation between adenoid hypertrophy, tonsil hypertrophy and overweight or obesity in children, but the probability of children overweight or obesity increases with age, and the proportion of obesity in children aged 7-12 years is higher.

[Demographic characteristics and canalith repositioning efficacy in 907 patients with typical benign paroxysmal positional vertigo]

AbstractObjective:To review the demographic characteristics and canalith repositioning efficacy in 907 patients with typical benign paroxysmal positional vertigo(BPPV). Method: The demographic characteristics of 907 patients with typical BPPV were statistically analyzed. According to the type of BPPV, patients were treated with the appropriate repositioning maneuver, and the clinical efficacy of repositioning maneuver was analyzed and summarized. Result: Nine hundred and seven patients of BPPV with typical nystagmus were elected in this study. 585 out of 907 were female and 322 out of were male, and the mean age was 53.10±14.25(13 to 89) years. The lesion located to the posterior semiCIrcular canal was 489 patients(53.9%), horizontal semiCIrcular canal was 312 patients(34.4%), anterior semiCIrcular was 63 patients(6.9%), and multiple semiCIrcular was 43 patients(4.8%). According to Kaplan-Meier survival analysis curve, the median cure time for the modified Semont and Epley repositioning maneuver in PC-BPPV groups was 3 days, and there was no significant difference in survival curves between the two repositioning maneuver. Meanwhile, the median cure time for Barbecue and Li horizontal canal quick repositioning maneuver groups was 3 days, and 1 day for Gufoni repositioning maneuver group in HC-BPPV groups. And there was no significant difference in survival curves among the three repositioning maneuver. In the AC-BPPV, 7 cases, 31 cases, 57 cases, 58 cases were cured with the Li anterior canal quick repositioning maneuver in the 1st day, the 3rd day, 1 week later, and 1 month later, and 5 cases lost to be follow-up. According to Kaplan-Meier survival analysis curve, the median cure time for the Li anterior canal quick repositioning maneuver in AC-BPPV groups was 3 days. Conclusion:Repositioning maneuver represents a simple, safe, rapid and effective approach to the treatment of BPPV. Therefore, repositioning maneuver should be choice for the BPPV treatment.

[A randomized controlled trial on short-term efficacy of the modified Semont maneuver for the treatment of posterior canal benign paroxysmal positional vertigo]

Objective:To observe the short-term efficacy of modified Semont maneuver for posterior canal benign paroxysmal positional vertigo (PC-BPPV)Method:This was a prospective randomized controlled trial on 130 PC-BPPV patients. Subjects were randomized divided into two groups: modified Semont (65 patients),and Epley(65 patients).Each maneuver was repeated twice,and the presence of sequelae,nystagmus and vertigo on positional testing were evaluated 3rd day and 1 week after treatment.Result:Five patients were lost to follow up (all five in the modified Semont group),and three patients failed to complete treatment (all three in the Epley group). The sequelae at the 3rd day and one week after modified Semont maneuver were 27 and 9,while 41 and 15 in Epley group. The efficacy rates at the 3rd day and one week after modified Semont maneuver were 91.7% and 98.3%,and 91.9% and 96.8% in Epley group retrospectively. The sequelae and short-term effective rate of patients in modified Semont group was no difference when compared with that in Epley group (P>0.05).Conclusion:Modified Semont maneuver represents a simple rapid and effective approach to the treatment of posterior canal benign paroxysmal positional vertigo.

Far upstream element-binding protein 1(FUBP1) expression differs between human colorectal cancer and non-cancerous tissue

Presented study aimed to detect the expression of far upstream element-binding protein 1 (FUBP1) in clinical samples of colorectal carcinoma (CRC) and explore the correlations of their expression with the clinicopathological characteristics of CRC.The streptavidin-perosidase (SP) method of immunohistochemistry was used to detect the expression of FUBP1 in 34 cases of colorectal cancer and their surrounding surrounding normal tissue, 30 cases of adenoma tissue. Using fluorescent quantitative reverse transcription polymerase chain reaction (qPCR), the expression of FUBP1 mRNA was measured in colorectal cancer and its surrounding normal tissue from 32 patients. FUBP1 protein expression level was detected by the Western blot method in 32 pairs of colorectal cancer tissue and surrounding normal tissue, and 30 cases of adenoma tissue.The positive rate of FUBP1 was detected through histochemistry in colorectal carcinomas (82.3%) which was higher than that in colorectal adenomas (46.7%) and surrounding normal tissues (20.5%). The relative amount of FUBP1 mRNA by qPCR method in colorectal carcinoma tissues (0.2703±0.1118) was higher than that of surrounding normal tissues (0.1898±0.0635; P<0.05). The Western blot showed that FUBP1 was mainly expressed in colorectal carcinoma tissues (0.6499±0.1473),which barely expressed in adenoma tissues (0.3756±0.1377; P<0.05) and surrounding normal tissues (0.1675±0.0613; P < 0.05).FUBP1 expression differs among colorectal tissues, which is overexpressed in colorectal carcinoma tissue. Further studies are needed to explore the role of FUBP1 in the pathogenesis of colorectal carcinoma.

[Expression of cyclin dependent kinase inhibitor p27 during proliferation in vascular smooth muscle cell]

This study was to investigate cell cycle distribution of the vascular smooth muscle cells (VSMCs) and negative regulator of cell proliferation p27 expression caused by platelet derived growth factor BB (PDGF-BB), angiotensin II (Ang II) and arginine vasopressin (AVP). Deprived of fotal calf serum for 48 h, cultured VSMCs in quiescent condition were collected at different times after stimulation of Ang II, AVP and PDGF-BB. Cell cycle distribution and p27 expression were determined with a flow cytometer. The results showed that the protein content of VSMCs was significantly increased (43.6%) by Ang II as a result of hypertrophy, but Ang II did not lead to downregulation of p27. AVP could downregulate p27 slightly. PDGF could inhibit p27 expression significantly and cause VSMCs hyperplasia. These results suggest that the progression of VSMCs through G1 to S phase might be brought out by the inhibition of p27 during proliferation.
