Objective To summarize and analyze the clinical experiences of treatment of complicated geriatric odontoptosis for the purpose of establishing a better technique to cope with such situation.Method The data of 542 outpatients with geriatric odontoptosis,from 1998 till the present treated in the Department of Outpatient,General Hospital of PLA,were summarized and analyzed according to the type and location of odontoptosis,with complications such as severe attrition,periodontitis,food impaction and detective occlusion.The special prosthetic designs on certain cases were also summarized.Some cases were followed-up.Results Removable partial dentares(RPD)with cast framework were prescribed to the geriatric odontoptosis patients.According to the site and type of odontoptosis,four special designed frameworks include casting fence-wall enforced artificial tooth prosthesis for lower clearance cases,metal strengthened plastic occlusive pad or metal occlusive pad for severe attrition cases,casting splint prosthesis for periodontal and food impaction with impaction preventive denture.36 cases were followed up for two years with satisfactory result in 31 cases,but in four cases the clasp was broken.In the cases with failure the dentures were redesigned and fabricated with cast framework,and better results were accomplished.Generally,the patients were accustomed to the new RPD quickly and revisit times were less frequent.The strength of prosthesis was enhanced.It was proved that custom designed framework could solve the clinical dilemma of severe dentition attrition,food impaction and periodontitis,and the odontoptosis was repaired.Conclusion The designed fence-wall prosthesis,metal strengthened plastic occlusal pad and metal occlusal pad,casting splint prosthesis and casting food impaction stop are effective prosthetic procedure for certain cases.

Objective To study clinical evaluation of xinqin granule combined with loratadine in treatment of allergic rhinitis and its effects on serum eosinophil(EOS),colony stimulating factor(CSF)and tumor necrosis factor(TNF)-α.Methods 90 patients of allergic rhinitis who received therapy from January 2014 to November 2016 in our hospital were selected.According to random number table,those patients were divided into the observation group(n=45)and the control group(n=45).The control group was treated with loratadine,while the observation group was combined with xinqin granule.Then the serum EOS,CSF and TNF-α,symptom score,clinical efficacy and adverse reactions were compared.Results After treatment,the serum levels of EOS,CSF and TNF-αin the observation group were significantly lower than that of the control group(P<0.05); the symptom score in the observation group was significantly lower than that of the control group(P<0.05); the total effective rate in the observation group was significantly higher than that of the control group[93.33％(42/45)vs.73.33％(33/45)](P<0.05); there was no significant difference in the incidence of adverse reactions between the two groups.Conclusion Xinqin granule combined with loratadine is well for allergic rhinitis,which can effectively reduce serum levels of EOS,CSF,TNF-α,relieve clinical symptoms,it's worthy of application and promotion.

Objective To explore the effect of ProSeal laryngeal mask airway and endotracheal tube on analepsia stage of general anesthesia in geriatric patients undergoing radical mastectomy.Methods Thirty geriatric females with breast cancer of American Standards Association (ASA)Ⅰ-Ⅱscheduled for selective radical mastectomy under general anesthesia were randomly allocated to two groups: ProSeal laryngeal mask airway group(PLMA group, n=15) and endotracheal tube group (ET group, n=15). The patients were put on PLMA or were intubated with ET under general anesthesia in the two groups, respectively. The heart rate (HR), systolic blood pressure(SBP)and diastolic blood pressure (DBP) were recorded at the time points of 5 min after entering operation room (T0), end of surgery (T1), opening eyes (T2), after extubation (PLMA) immediately (T3) and 3 min after extubation (PLMA) (T4). The numbers of patients who were given antihypertensive agent,showed bucking, agitation or sore throat, nausea and vomiting after extubation were recorded during the analepsia stage of general anesthesia. Results The blood pressure (BP) and HR were mildly.increased in PLMA group at T2, and there was no significant difference compared with T0(P＞0.05). But the BP and HR were significantly higher at T3 than at T0 (P＜0.05). In ET group, the BP and HR were both significantly elevated at T2 and T3 than at T0 (P＜0.05), and reached the peak at T3. The increased levels of BP and HR were significantly lower in PLMA group than in ET group at T2 and T3 (P＜0.05). The quantities of patients who were given antihypertensive agent, showed bucking and sore throat were less in PLMA group than in ET group(P＜0.05). No differences in incidence rate of agitation, nausea and vomiting after extubation between the two groups were observed(P＞0.05). Conclusions PLMA can obviously reduce the occurrence of complications in analepsia stage of general anesthesia in geriatric patients scheduled for selective radical mastectomy,and is beneficial to provide much safer anesthesia.

Objective To explore the prevalence and related risk factors of thyroid nodule in elderly patients(age ≥ 60 years old) with type 2 diabetes mellitus(T2DM)) in Xinjiang region.Methods Two hundreds and two elderly patients with T2DM were selected,including 91 cases of thyroid nodule(thyroid nodule group) and111 cases of non-thyroid nodule (control group).The disease history,body mass index(BMI),fasting blood-glucose (FBG),2-h postprandial blood glucose(2 h PBG),glycosylated hemoglobin(HbA1c),triglyceride(TG),cholesterol(TC),high-density lipoprotein(HDL-C) and low density lipoprotein(LDL-C) were collected for statistical analysis.Results The age,gender,BMI,TC and HbA1c had statistical difference between the two groups (P<0.05);the disease course,pulse pressure,systolic pressure,abdominal perimeter,smoking history,HDL,TG,FBG and 2 h PBG had no statistical differences netween the thyroid nodule group and non-thyroid nodule group (P>0.05).The multivariable Logistic regression analysis showed that the age,gender,TC,HbA1c and BMI were the risk factors of thyroid nodule occurrence.Conclusion Conducting the thyroid nodule related imaging examination has an important clinical significance for diabetic elderly women patients with obesity and cholesterol increase.

To observe the morphological changes in photoreceptor after experimental retinal detachment in cats. Twenty eight cats were divided into experimental group and control group. Retinal detachment was produced by injecting 0 25% solution of Healon into the subretinal space with the aid of a micropipette. Histologic sections of retina were processed for light and electron microscopy at detachment intervals ranging from 0 5 days to 3 months. At 24 hours postdetachment, the outer segments were distended and disrupted, but the inner segments and photoreceptor cell bodies were only slightly affected. 3-14 days after detachment, the inner segments were affected at multiple sites, albeit to varying degrees. Some of them were vacuolizated at the tip, with mitochondria swollen and cristae fragmented. At the same time, the photoreceptor cell bodies often showed a distension of endoplasmic reticulum, deterioration of mitochondria, and the presence of multivesicular bodies. 1-3 months after detachment, large empty spaces in the outer nuclear layer and a progressive loss of cytoplasmic ground substance and organelles appeared in some photoreceptors as detachment duration lengthened. Necrosis of the inner segments and cell bodies were more marked in the more serious detachment than those in shallow ones. Degenerative changes occured in the photoreceptor very soon after experimental retinal detachment, and these changes were correlated with both the depth and duration of retinal detachment.

Objective To investigate the causes, diagnosis and treatment of infants with secondary methylmalonic aciduria due to maternal vitamin B 12 deficiency. Methods The clinical, laboratory data and treatment of 7 children with secondary methylmalonic aciduria and their mothers′ health and nutrition were retrospectively reviewed. Results All children were presented to the hospital with vomiting, seizures or mental retardation during 1 to 13 months after birth. Varied degrees of anemia was found in 6 infants and 5 with metabolic acidosis and liver dysfunction. Methylmalonic aciduria was found in all subjects. Four of the mothers had chronic gastritis, one with gallstones in liver and gallbladder and one was a vegetarian. Decreased serum level of vitamin B 12 and folic acid and elevated homocystine concentrations were found in all mothers. After vitamin B 12 and folic acid supplementation, significant improvement was observed in all patients. Six infants showed normal development and one had mild mental retardation. Conclusions Chronic gastritis, liver/gall bladder diseases or being a vegetarian might lead to maternal vitamin B 12 deficiency and then infantile secondary methylmalonic aciduria. Early diagnosis and vitamin B 12 and folic acid supplement are crucial in improving the prognosis.

Objective To explore the influence of social support on compliance of respiratory function exercise and rehabilitation in patients with coronary artery bypass graft surgery. Methods A total of 102 patients with coronary artery bypass graft surgery were evaluated by General Data Survey Scale,Social Support Questionnaire and Compliance of Respiratory Function Exercise Scale.According to the situation of patients′social support, patients were divided into high score group,medium score group and low score group, then compliance of respiratory function exercise,postoperative ICU stay time, postoperative ventilation time, postoperative hospital stay, 6-min walking test (6MWD) and left ventricular ejection fraction (LVEF) were compared among three groups. Results The social support of patients with coronary artery bypass graft surgery in medium level,the score was (34.70 ±7.46) points. The postoperative ventilation time, postoperative ICU stay time in high score group were less than those in medium score group and low score group:(17.79±5.30) h vs. (42.41±14.18), (80.00±11.15) h, (24.29±6.00) h vs. (55.66±16.31), (92.46±10.21) h, and there were significant differences, F=47.340,110.252,P<0.01. The compliance of respiratory function exercise,6MWD and LVEF in high score group were better than those in medium score group and low score group:(38.93±24.37) points vs.(30.26±4.79), (19.85±4.45) points, (376.07±55.92) m vs. (328.83±59.27), (302.04±60.24) m, (60±4)%vs. (53±9)%, (51±10)%, and there were significant differences, F=286.040, 55.228, 20.159,P < 0.01. Conclusions Social support can improve the patients′adherence to treatment, and enhance the patients′ability to cope with stressful events,then accelerate the process of postoperative rehabilitation of patients effectively,and improve quality of life.

Objective To assess the efficacy and safety of target-controlled infusion of propofol and remifentanil in geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation. Methods Thirty geriatric patients with primary hepatocellular carcinoma of ASA Ⅱ-Ⅲ scheduled for percutaneous radiofrequency ablation under monitored anesthesia care (MAC) were randomly allocated to two groups: target-controlled infusion of propofol and remifentanil group (PR group, n= 15) and intravenous injection of midazolam and fentanyl group (MF group. n= 15). The mean arterial blood pressure (MAP), heart rate (HR) and pulse oxygen saturation (SpO2) of patients were recorded during the treatment. The Ramsay Score, Patient Cooperation Score, VAS Score and postoperative Patient Satisfaction Score were recorded as well. Results The Ramsay Score, Patient Cooperation Score, VAS Score and Patient Satisfaction Score were all higher in PR group than in MF group (all P<0.05). The maximum values of MAP and HR [( 108.7± 8.6) mm Hg, (83.8±7.1) times/min] were significantly higher than the baseline values [( 99.3 ± 8.5) mm Hg, (76.3±7.1) times/min] in MF group, and the degree of increment of MAP and HR were significantly greater in MF group than in PR group (both P<0.05). The minimum values of MAP and HR [(84.5±6.5) mm Hg, (66.6 ± 6.6) times/min] were significantly lower than the baseline values [(97.7±6.5) mm Hg, (75.4±7.3) times/min] in PR group, and the degree of decrement of MAP and HR were significantly greater in PR group than in MF group (both P<0.05). SpO2 of both groups decreased significantly (the minimum values of PR and MF groups were 95.1±2.0 and 95.5± 2.2, respectively), but there was no statistical difference between two groups (P>0.05) . Conclusions MAC with target-controlled infusion of propofol and remifentanil is more suitable for geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation, as it can provide ideal analgesia and sedation, but the respiration and the change of hemodynamics of patients must be observed seriously.
