Objective To study the periodontal status and risk factors for periodontitis in periodontitis patients at different ages in wuhan. Methods From January 2007 to March 2008, the cross-sectional survey on periodontal conditions of 493 physical examinees in Wuhan city was carried out with random cluster sampling method. 458 cases of them were in accordance with the inclusive criteria and were stratified into two groups: young and middle-aged adults (aged 30-59 years) and old adults (aged 60 years and over). A case-control study was carried out in the periodontitis cases group (n=280) and the control group (n=178). Database was created by SQSERVER2000 and SPSS11.0 was used for statistical analysis. The relationship of periodontitis with age, gender, nation, educational background, diabetes mellitus, smoking, drinking, mental pressure and oral hygiene habits were analyzed by univariate and multivariate logistic regression analysis. Results The prevalence of periodontitis was 61.1% (280/458). Univariate analysis revealed that age, educational background, diabetes mellitus, smoking and oral hygiene habits were related factors for periodontitis (OR:0.44, 2.27, 3.44, 1.75, 9.82, P<0.05 or P<0.01). Meanwhile, multivariate analysis showed that suffering from diabetes mellitu and low educational background were the independent risk factors for periodontitis (OR=2.66, 1.95, all P<0.05). After stratification by age, multivariate logistic regression analysis showed that there was no correlation between diabetes mellitus and periodontitis prevalence in young and middle-aged adults and diabetes mellitus was a risk factor for periodontitis in old adults(OR=6.91, 95%CI: 1.27～37.42). Conclusions There are many risk factors for periodontitis and diabetes plays a major role in the development of periodontitis in old adults.

Objective:To investigate the effect of multiple-modality exercise on symptom clusters and nutritional status of nasopharyngeal carcinoma patients with radiotherapy.Methods:A total of 92 nasopharyngeal carcinoma patients who received radiotherapy in the Panzhihua Center hospital were randomly divided into research group and control group, each group contained 46 cases. The control group received routine nursing and the research group received 4-week multiple-modality exercise. The scores of M.D. Anderson symptom inventory-head & neck module (MDASI-H&N), patient-generated subjective global assessment (PG-SGA) and other biochemical nutrition index were compared before and after intervention between two groups.Results:After intervention, the scores of fatigue, poor appetite, dry mouth, mouth/throat mucus, dysgeusia were 3.77±1.30, 3.48±1.22, 3.81±1.48, 4.24±0.83, 4.94±1.63 in the research group and 4.36±1.09, 4.52±1.25, 4.39±1.24, 4.24±0.83, 6.03±2.00 in the control group, respectively. Those scores were significantly decreased in the research group compared to the control group ( t value was 1.996-3.993, P<0.05). After 4 weeks of intervention, the PG-SGA total socres, body mass index, prealbumin, hemoglobin were 2.78±0.60, (22.08±2.61) kg/m 2, (199.60±27.16) mg/L, (105.59±17.62) g/L, those indexes were 4.14±1.08, (20.63±2.63) kg/m 2, (193.42±25.57) mg/L, (102.77±18.57) g/L, the total scores of PG-SGA were significantly decreased in the research group compared to the control group ( t value was 7.356, P<0.01). Conclusions:Multiple-modality exercise can alleviate symptom burden and promote nutritional status of nasopharyngeal carcinoma patients with radiotherapy.

Objective: To observe clinical effect of thunder-fire moxibustion with meridian point, including lumbar spinal cordacupoints of bladder meridian and abdominal acupoints of Ren channel, which treating on deficiency of kidney and spleen and blood stasis in chronic kidney diseases (CKD) stage 3. Methods: Totally 60 patients were randomly divided into treatment and control group. 30 patients in control were treated with blood pressure and lipid adjustment, Chinese medicine and nutritional therapy. 30 patients in treatment group were treated with thunder-fire moxibustion with meridian point based on control. A moxibustion-treated course has 2 weeks, patients were treated every other day. Observe blood urea nitrogen (Bun) , creatinine (Scr) , glomerular filtration rate (eGFR) , Chinese medicine syndrome and quantitative score, as well as clinical efficacy. Results: After 4 weeks of intervention, the TCM syndrome score [8 (4,10)] in the treatment group was significantly lower than that in the control group [12 (10,14)], with a statistically significant difference (Z=-3.706, P = 0.000); in the quantitative score of symptom classification, the patients in the treatment group were significantly lower than those in the control group [2 (0,2)], chills [2 (2,2)], fatigue [2 (2,4)], the difference was statistically significant (Z=-2.625, -3.593, -4.609, P < 0.01). The frequency of nocturia in the treatment group was significantly higher than that in the control group (Z=-1.989, P < 0.05), while that in the treatment group was not significantly better than that in the control group (P > 0.05). In terms of clinical efficacy, the total effective rate of the treatment group was 93.3% (28/30), which was better than73.3% (22/30) of the control group (χ²= 38.19, P = 0.000). Conclusion Thunder-fire moxibustion with meridian point improve deficiency of kidney and spleen and blood stasis of patients in CKD stage3, such as weak waist, cold chills, poor appetite, weakness and nocturia, as well as ameliorate renal function.

Objective:To explore the diagnostic accuracy and application value of 3.0 T non-contrast coronary magnetic resonance angiography (CMRA) in evaluating coronary artery in children with Kawasaki disease (KD).Methods:From May 2019 to January 2022, 75 children diagnosed with KD in our hospital were enrolled. All the patients underwent CMRA and transthoracic echocardiography (TTE) in one week, twenty-six of whom underwent coronary CT angiography (CCTA) or invasive coronary angiography (ICA) within two weeks. The diagnostic performance of CMRA and TTE was evaluated with CCTA/ICA as reference standard by per-patient basis, per-vessel basis, per-segment basis. Sensitivity and specificity of CMRA and TTE was compared by paired chi square test.The distribution of coronary artery aneurysm (CAA), thrombosis and other pathological changes of coronary artery were recorded and compared between two methods. The patients′ height and weight were collected to calculate the Z value. Z value>2.5 was defined as CAA.Results:All patients successfully completed CMRA examinations. Among the 26 patients, the sensitivity of CMRA was significantly higher than that of TTE by per coronary artery[97.7%(43/44)vs.84.1%(37/44), χ2=4.17, P<0.05]. CMRA showed a higher sensitivity than that of TTE both by proximal segments and middle/distal segments [97.7%(43/44)vs. 84.1%(37/44), 100%(21/21) vs. 52.4%(11/21), χ2=10.08, 7.11, both P<0.05). A total of 115 CAAs was found by CMRA, while only 87 (75.7%) CAAs were observed by TTE. Of the 28 (24.3%) CAAs missed by TTE, 16 (57.1%) were located in right coronary artery (RCA), 2(7.1%) in left main coronary artery, 7(25.0%) in left anterior ascending coronary artery (LAD) and 3(10.7%) in left circumflex coronary artery (LCX). Eleven (39.3%) missed CAAs by TTE were located in the proximal segment of RCA, LMCA, LAD and LCX, and 17 (60.7%) missed CAAs were located in the middle and distal segments. TTE missed coronary thrombosis in 5 patients compared with CMRA. Conclusions:3.0 T non-contrast CMRA is non-invasive and non-radiation, and the image quality can meet the needs of diagnosis, especially for detection of CAAs in RCA or in middle and distal segments of coronary artery in KD patients.
