OBJECTIVE: To assess the therapeutic effect and study the role of nasal mucosa epithelization after endoscopic surgery using the plasma radiofrequency ablation at low temperature in patients with nasal inverted papilloma. METHOD: The clinical data of 104 patients with nasal inverted papilloma underwent endoscopic surgery u sing the plasma radiofrequency ablation at low temperature from July, 2008 to July, 2012 were analyzed,and the recovery of mucosa was observed under nasal endoscope. RESULT: The mucosa recovery extent showed a decreasing trend from mucosa pattern degree I to III, where the difference was statistically significant by chi-square test between groups (P < 0.05). The average epithelialization time was 2.7 months. It showed a significantly decreasing trend among average epithelialization time of different degrees of mucosa (P < 0.05). The nasal mucosa of most patients completed epithelialization 2.9 months after surgery. CONCLUSION It is safe and effective to treat nasal inverted papilloma with plasma radiofrequency ablation at low temperature. The patients should be followed up with regular reexamination for at least three months after surgery.

OBJECTIVE: To investigate the sleep monitoring feature of the MSMS in elderly patients with OSAHS. METHOD: One hundred and ninety patients diagnosed with OSAHS were divided into elderly group and non elderly group according to age, then the results of MSMS were analyzed. RESULT: Majority elderly patients were with mild to moderate OSAHS. The nocturnal mean blood oxygen and the lowest oxygen were higher than non elderly group, coupled with higher percentage of the total oxygen saturation < 90% monitoring time (TS90). There was no significant difference in sleep structure between two groups, but the total sleep time of elderly group is lower than the non elderly group, the difference is statistically significant. CONCLUSION The elderly patients with OSAHS were less severe in nature, but the nocturnal hypoxia last longer in the elderly group. There is no significant difference in the sleep structure between the two groups. But the total sleep time decrease in elderly group. With smaller interference, the MSMS is closer to the natural sleep stustus of the subjects.

Objective To investigate the effect of metoprolol and metoprolol combined with moderate inten-sity aerobic exercise on the sympathetic vasoconstriction response of skeletal muscle, functional sympatholysis and the exercise capacity of hypertensive men. Methods Thirty men with mild ( stage 1) essential hypertension were divi-ded into a drug group and an observation group. The drug group received only metoprolol while the observation group took metoprolol and performed aerobic exercise (intensity 50-70％ of VO2max, 30-45 min/time, 3-5 times/week) for 12 weeks. Before and after the experiment, the subjects' maximum oxygen uptake (VO2max), peak power (PP) as well as a rating of perceived exertion ( RPE) curve during exercise were determined using the graded exercise test. Forearm vascular conductance ( FVC) induced by the cold pressor test was measured using Doppler ultrasound at rest and during a handgrip exercise. Sympathetic vasoconstriction response was manifested by the rate of change in the conductance (％FVC) before and after the cold pressor test. Functional sympatholysis ( the ability of muscle contrac-tions to inhibit sympathetic vasoconstrictor response) was quantified using the difference in the ％FVC values (△％FVC) between the handgrip exercise and at rest. Results After the treatment,％FVC during the handgrip exercise was lower than at rest in the observation group.△％FVC had increased significantly, as had VO2max and PP. The RPE curve during a graded exercise test shifted to the right in the observation group, but there was no significant change in the other observations. In the drug group, PP had decreased significantly and the RPE curve had shifted to the left. Conclusion Metoprolol can better improve functional sympatholysis and enhance exercise capacity when it is com-bined with moderate intensity aerobic exercise. That will alleviate any exercise intolerance in men with mild hyperten-sion caused by taking metoprolol alone.

Objective:To evaluate the influence of 25-hydroxyvitamin D[25(OH)D]on dyslipidemia in elderly female patients with type 2 diabetes(T2DM)mellitus aged 60 or over.Methods:We retrospectively reviewed the clinical records of 175 type 2 diabetic older women meeting the inclusion criteria, admitted to the Department of Endocrinology, Beijing Chuiyangliu Hospital, between January and December 2020, with an average age of 66(63, 70)years.According to the diagnostic criteria of dyslipidemia(cholesterol ≥6.2 mmol/L, high density lipoprotein cholesterol <1.0 mmol/L, low-density lipoprotein cholesterol ≥4.1 mmol/L or triglycerides ≥2.3 mmol/L), 110 participants(62.9%)were divided into a dyslipidemia group and 65 participants(37.1%)were assigned into a normal blood lipid group.Logistic regression was employed to investigate factors influencing dyslipidemia.Spearman correlation analysis was employed to analyze the correlation between serum 25(OH)D and blood lipid indexes.Results:The median serum 25(OH)D level of the 175 subjects was 10.92(8.1, 15.2)μg/L.For the dyslipidemia group, it was 9.1(5.8, 12.9)μg/L, lower than 11.9(8.4, 22.6)μg/L in the normal blood lipid group.The proportion of people with hypertension in the dyslipidemia group was higher than in the normal blood lipid group.The dyslipidemia group also had higher BMI, waist circumference and homocysteine levels( P<0.05). Results of multivariate logistic regression analysis demonstrated that hypertension, waist circumference, and homocysteine were significant risk factors for dyslipidemia in elderly women with T2DM, whereas serum 25(OH)D was a protective factor( P<0.05). Correlation analysis results identified that cholesterol and low density lipoprotein cholesterol were inversely correlated to 25(OH)D while high density lipoprotein cholesterol was positively correlated to it( P<0.05). Conclusions:There is a serious deficiency of serum 25(OH)D in older women with T2DM.25(OH)D is protective factor in elderly T2DM women against dyslipidemia.Clinicians should pay attention to vitamin D deficiency in patients during diagnosis and treatment and correct the deficiency.

Objective To compare the effects of rat proinsulin gene therapy via intraportal infusion and intramuscular injection blood glucose level in streptozotocin-induced diabetic rots. Methods (1) Recombinant eukaryotic cell expression plasmid of rat proinsulin gene pCMV/proiusulin was transferred into streptozotocin-induced diabetic rats by intraportal infusion and intramuscular injection to observe the effect of rat proiusulin gene therapy in diabetic rats. The treatment group by intraportal infusion (group A) and the group by intramuscular injection (group C) were given pCMV/proinsulin naked plasmid DNA 100 μg, while the control groups by intraportal infusion (group B) or by intramuscular injection (group D) were treated with similar amount of pCMV DNA. Normal group and diabetes mellitus group were also observed at the same time. (2) Blood glucose level was tested and serum insulin was determined by radioimmunoassay. RT-PCR and immunohistochemistry were used to detemine proinsulin mRNA and protein expressions in liver and skeletal muscle and protein. Results (1) The blood glucose levels in two treated groups were both decreased. In group A, levels of blood sugar decreased about 7 mmol/L and glycemie control was maintained for 3-4 weeks. Serum insulin levels step up significantly after pCMV/proinsulin gene therapy. The blood glucose level in group A was significantly lower than those of group B and DM group (P<0.05), while the serum insulin level was higher than those of two groups (P<0.05). In group C, blood glucose levels decreased about 4 mmol/L and glycemic control was maintained for 1-2 weeks. Meanwhile, the concentrations of insulin increased markedly after gene therapy. The blood glucose in group C was significantly lower than those of group D and DM group (P<0.05), while the serum insulin level was higher than those of two groups (P<0.05). (2) Proinsulin mRNA and protein expressions could be detected in either hepatic cell of group A or skeletal muscle cell of group C, not in group B and group D. Conclusion Proiusulin genetherapy via intraportal infusion or intramuscular injection lowers significantly blood glucose in diabetic rats, and thus offers a potential approach to treatment of diabetes.

OBJECTIVES: This study aims to determine the effects of low-level laser (LLL) on the expression of interleukin-6 (IL-6), tumor necrosis factor (TNF)-α, osteoprotegerin (OPG), and receptor activator of nuclear factor-κB ligand (RANKL) in human periodontal ligament cells (HPDLCs) stimulated by high glucose; and identify the molecular mechanism of LLL therapy in the regulation of periodontal inflammation and bone remodeling during orthodontic treatment in diabetic patients. METHODS: HPDLCs were cultured in vitro to simulate orthodontic after loading and irradiated with LLL therapy. The cultured cells were randomly divided into four groups: low glucose Dulbecco's modification of Eagle's medium (DMEM)+stress stimulation (group A), high glucose DMEM+stress stimulation (group B), hypoglycemic DMEM+LLL therapy+stress stimulation (group C), and hyperglycemic DMEM+LLL therapy+stress stimulation (group D). Groups C and D were further divided into C1 and D1 (energy density: 3.75 J/cm²) and C2 and D2 (energy density: 5.625 J/cm²). Cells in groups A, B, C, and D were irradiated by LLL before irradiation. At 0, 12, 24, 48, and 72 h, the supernatants of the cell cultures were extracted at regular intervals, and the protein expression levels of IL-6, TNF-α, OPG, and RANKL were detected by enzyme-linked immunosorbent assay. RESULTS: 1) The levels of IL-6 and TNF-α secreted by HPDLCs increased gradually with time under static pressure stimulation. After 12 h, the levels of IL-6 and TNF-α secreted by HPDLCs in group A were significantly higher than those in groups B, C1, and C2 (P<0.05), which in group B were significantly higher than those in groups D1, and D2 (P<0.01). 2) The OPG protein concentration showed an upward trend before 24 h and a downward trend thereafter. The RANKL protein concentration increased, whereas the OPG/RANKL ratio decreased with time. Significant differen-ces in OPG, RANKL, and OPG/RANKL ratio were found among group A and groups B, C1, C2 as well as group B and groups D1, D2 (P<0.05). CONCLUSIONS 1) In the high glucose+stress stimulation environment, the concentrations of IL-6 and TNF-α secreted by HPDLCs increased with time, the expression of OPG decreased, the expression of RANKL increased, and the ratio of OPG/RANKL decreased. As such, high glucose environment can promote bone resorption. After LLL therapy, the levels of IL-6 and TNF-α decreased, indicating that LLL therapy could antagonize the increase in the levels of inflammatory factors induced by high glucose environment and upregulate the expression of OPG in human HPDLCs, downregulation of RANKL expression in HPDLCs resulted in the upregulation of the ratio of OPG/RANKL and reversed the imbalance of bone metabolism induced by high glucose levels. 2) The decrease in inflammatory factors and the regulation of bone metabolism in HPDLCs were enhanced with increasing laser energy density within 3.75-5.625 J/cm². Hence, the ability of LLL therapy to modulate bone remodeling increases with increasing dose.
