Objective To investigate the dietary structure,nutrition and health status of elderly military cadres.Methods Questionnaire,dietary investigation and physical examination were performed in elderly cadres in Hangzhou Sanitarium in 1992,2002 and 2008(520,720 and 643 cases,respectively).The dietary structure,nutrition and health status were analyzed systematically.Results The intake of cereals dropped,and also the dried legumes.The intake of meats and aquatic products was significantly increased,and the intake of all the vegetables,fruits,dairy products,nuts and vegetable oils was rapidly increased too.The intake of pickles was decreased.The intake of salt and soy sauce showed a insignificant tendency of change.The intake of food supplying energy and protein had exceeded the recommended nutrient intake(RNI).The intake of niacin,vitamin E and Fe was increased gradually and reached the standard of RNI.Vitamin B1 intake also reached that of RNI.Vitamin C intake was increased rapidly,and reached 176.0?23.5mg/d in 2008.Zinc intake was not enough in 1992,while reached the standard of RNI in 2002 and 2008.Selenium intake reached RNI in 2008.With the increasing of milk consumption,calcium intake had greatly improved.There was also an increase in the proportion of energy from fat,which reached 37% in 2008.The health status of military old cadres had greatly improved.The prevalence of digestive diseases and hyperosteogeny decreased significantly by years,while the cardiovascular and cerebrovascular diseases increased.Conclusions The nutrition status and the quality of average diet in military elderly cadres have improved obviously,while the intake of fat,cholesterol and sodium is excessive.As a result,overweight,obesity and hypertension are prevalent.Propagation of nutrition knowledge and nutrition intervention should be emphasized.

Objective To investigate the changes to eotaxin,tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in plasma from patients with chronic urticaria treated with the combination of polysaccharide nucleic acid fraction of bacillus Calmette-Guerin (BCG-PSN) and cetirizine.Methods Totally,123 patients with chronic urticaria were enrolled into this study,and classified into two groups:the combination therapy group (n =60) treated with intramuscular BCG-PSN 2 ml every other day and oral cetirizine 10 mg once daily,and the monotherapy group (n =63) treated with oral cetirizine 10 mg once daily alone.The treatment lasted 54 days.Clinical efficacy was evaluated.Venous blood samples were collected from the patients before and after the treatment,as well as from 56 healthy controls.Enzyme-linked immunosorbent assay was performed to quantify the plasma levels of eotaxin,TNF-α and IFN-γ.Results At the end of the treatment,the total response rate was significantly higher in the combination therapy group than in the monotherapy group (88.3％ vs.63.4％,P ＜ 0.05).Before the treatment,no significant differences were observed in the plasma levels of eotaxin,TNF-α or IFN-γ between the two treatment groups,whereas the patients showed higher plasma levels of eotaxin and TNF-α but lower plasma level of IFN-γ compared with the healthy controls (all P ＜ 0.5).Both the combination therapy and monotherapy resulted in a statistical decrease in plasma eotaxin and TNF-α but an increase in plasma IFN-γ (all P ＞ 0.05),and the absolute values of changes in the three parameters were significantly higher in the combination therapy group than in the monotherapy group (eotaxin:(13.27 ± 4.11) μg/L vs.(8.12 ± 2.58) μg/L,t =8.3654,P ＜ 0.05; TNF-α:(12.38 ± 3.95) ng/L vs.(10.32 ± 3.41) ng/L,t =3.1005,P ＜ 0.05; IFN-γ:(17.06 ± 5.24) μg/L vs.(12.54 ± 4.07) μg/L,t =5.3573,P ＜ 0.05).Further more,the differences between the patients and healthy controls in the three parameters disappeared at the end of the treatment (all P ＞ 0.05).Conclusion BCG-PSN combined with cetirizine seems superior to cetirizine alone for the treatment of chronic urticaria.

Objective To study the effect of active respiratory circulation combined with incremental resistance exercise on exercise endurance in elderly patients with rheumatic heart disease.Methods A total of 120 elderly patients with rheumatic heart disease hospitalized in the cardiac rehabilitation department of this hospital from October 2021 to October 2022 were selected as the study subjects and divided into the observa-tion group and control group by the random number table method,60 cases in each group.The patients in the control group were treated with the conventional treatment and rehabilitation nursing,and the observation group adopted the active respiratory circulation technique combined with incremental resistance exercise on the basis of the former.The 30 s arm flexion,2 min step test,6 min walking distance,cardiac function and nursing satisfaction on 1 d before training and 30 d after training were compared between the two groups.Re-sults The number of 30 s arm flexions and 2 min steps on 30 d after training in the observation group was higher than that in the control group[32.23(12.88,52.33)times vs.23.46(1.77,44.48)times,(9.62±0.48)times vs.(9.03±0.35)times],the 6-min walking distance was longer than that in the control group[(427.59±20.36)m vs.(394.89±17.95)m],the levels of LVEF and BNP were higher than those in the con-trol group[(56.32±3.60)％vs.(52.23±3.13)％,(645.00±9.12)pg/mL vs.(637.00±9.16)pg/mL],and the proportion of very satisfaction was higher than that in the control group(78.33％vs.21.66％),the differ-ences were statistically significant(P＜0.05).Conclusion Active respiration and circulation technology com-bined with incremental resistance exercise could effectively improve the flexion mobility ability of both upper limbs,the flexibility and exercise ability of both lower limbs,and improve the muscle strength of the limbs and cardiac function in elderly patients with rheumatic heart disease.
