Obesity has become a social problem.Study shows that fat is closely related with chronic diseases.and the effect of body fat on body metabolism varies with its distribution.The discovery of fat as an endocrine organ provides a broad research areas for the relationship between body fat and chronic diseases.The difierense in fat distribution between different sexes suggests that gonadal hormone has obvious effects on body fat metabolism.As a result,hormone replacement therapy has become the optimal method for releasing climacteric symptom.With the development of people's living standards,the attention paid to the menopausal problem,the research on body fat changes and its relationship with chronic diseases,and the study on the effect of hormone replacement therapy on the body fat are of great importance.

OBJECTIVE The aim of this study was to evaluate the outcomes of rehabilitation after cochlear implantation in children with malformed inner ear and compare them with a group of congenitally deaf children implantees with a normal inner ear.METHODS 21 children with inner ear malformation were retrospectively studied. The postoperative outcomes of these 21 cases were compared with that of 21 cases with normal inner ear structure. The assessment of all the children included the hearing levels, language ability , categories of auditory performance (CAP) and speech intelligibility rating (SIR) respectively before cochlear implantation, 6 months and 1 year after surgery. The data was analyzed using SPSS 17.0. RESULTS The results of rehabilitation in 9 children with Large Vestibular Aqueduct Syndrome and 6 cases with Mondini abnormality had no significant difference comparing with the control cases. The outcomes of 1case with severe Mondini abnormality and 5 cases with common cavity indicated significant worse than the control cases. CONCLUSION The effect of rehabilitation had no difference between the children with large vestibular aqueduct syndrome and the cases with normal inner structure after cochlear implantation, but was poorer in children with severe Mondini abnormality and common cavity. It was necessary to evaluate the degree of malformation of inner ear structure before cochlear implantation. The hearing abilities have improved quickly 6 months after cochlear implantation. The language abilities will need at least one year to get improved while the SIR need even more time. The development of language functions requires individualized rehabilitation guidance and integrated education.

Objective To detect the expression of vascular endothelial growth factor(VEGF)-C and VEGF-D in normal gastric tissue and gastric carcinoma tissue,and further investigate the relationship between VEGF-C,VEGF-D and lymph vessel density (LVD),lymph node metastasis.Methods The expression of VEGF-C and VEGF-D in gastric carcinoma tissues were examined by using SP immunohistochemical method in 30 normal gastric tissue and 75 gastric carcinoma tissue respectively.The lymph vessel were marked by LYVE-1 and calculated LVD.Results The rate of positive expression of VEGF-C and VEGF-D in gastric carcinoma tissue was significantly higher than that in normal gastric tissue,there was significant difference [73.3 ％ (55/75) vs.33.3 ％ (10/30),66.7 ％ (50/75) vs.30.0 ％ (9/30),P ＜0.01].The level of LVD in gastric carcinoma tissue with lymph node metastasis (40 cases) was significantly higher than that in without lymph node metastasis (35 cases)[(8.85 ± 1.24)/HP vs.(4.75 ± 1.04)/HP](P =0.000).The level of LVD increased when the expression level of VEGF-C and VEGF-D gradually went up.Conclusions The level of LVD increases in gastric carcinoma tissue.VEGF-C and VEGF-D are two significant factors for LVD and lymph node metastasis.

Objective To discuss the relationship between bone mineral salt metabolism index change and bone density in different stage of chronic kidney disease (CKD).Methods Three hundred and forty-five non-dialysis patients with CKD were enrolled in this study.According to the serum creatinine (SCr),glomerular filtration rate (GFR),they were divided into stage 1-5.CKD 1 had 75 cases,CKD 2 had 65 cases,CKD 3 had 65 cases,CKD 4 had 65 casès,CKD 5 had 75 cases.The level of blood calcium (Ca),phosphorus (P) and SCr were detected by ion selective electrode method.The level of urea nitrogen (BUN) was detected by picric acid method.The level of intact parathyroid hormone (iPTH) and 1,25 (OH)2VitD3 were detected by chemiluminescence.Results With the decline of renal function,the level of iPTH and blood P increased gradually,especially in stage CKD 4 and CKD 5,and compared with stage CKD 1,there were significantly differences [(289.6578 + 187.7945),(482.0667 + 232.2065) μ g/L vs.(77.8431 + 52.9760) μ g/L and (1.6938 + 0.1960),(2.6034 ± 0.5986) mmol/L vs.(1.3833 ± 0.4068) mmol/L,P ＜ 0.05].The level of blood Ca and 1,25 (OH)2VitD3 decreased gradually,especially in stage CKD 4 and CKD 5,and compared with stage CKD 1,there were significantly differences [(1.9185 +0.4633),(1.8293 ± 0.3075) mmol/L vs.(2.0893 + 0.2245) mmoi/L and (10.0892 + 0.2638),(7.6058 +0.4356) ng/L vs.(18.0036 + 0.3218) ng/L,P ＜ 0.05].With the decline of renal function,the proportion of osteoporosis also gradually increased,especially in stage CKDS,and compared with stage CKD 1 and CKD 2,there was significantly difference [60.00％ (45/75) vs.20.00％ (15/75),23.08％ (15/65),P ＜ 0.05].Conclusion With the decline of renal function,the level of blood P and iPTH increase,and blood Ca,1,25(OH)2VitD3,bone density decrease,especially in stage CKD 4 and CKD 5 patients.

Objective:To investigate the prevalence and related factors of dental caries in 3-year-old children in the Development District in Dalian.Methods:A multi-stage,randomized,cluster sampling method was used in the cross-sectional study.All 3-year-old children in the selected 15 kindergartens were invited to take part in the oral health examination conducted by 3 calibrated examiners.The WHO recommended caries diagnosis criteria were used.The structured questionnaire including the information of children's oral hygiene habits,dietary habits,parents' oral health knowledge and socioeconomic status was completed by the parents.Results:1 220 3-year-old children completed the clinical oral examination and 964 children's parents(79.0％) finished the questionnaire.The caries prevalence in 3-year-old children was 62.8％,and the mean dmft and dmfs scores were 3.40 and 7.34,respectively.No differences in the prevalence of caries,mean dmft and dmfs scores were found between boys and girls(P ＞0.05).Logistic regression analysis showed that the frequency of sweets and sugar-containing beverages consumption(P＜0.05),parents'education level(P＜0.05) were significantly related to the caries prevalence.Conclusion:The prevalence and severity of dental caries in 3-year-old children in Dalian Development District were high and the frequency of consumption sugar-containing foods and beverages,parents'education level were related to the decay prevalence.

Objective To assess the therapeutic effect of music- regulated laser therapy on mild and moderate primary hypertension (PH) so as to provide clinical evidence for the development of an effective non-drug therapy for hypertension. Methods One hundred mild and moderate PH patients were divided into obser-vation ( n = 50 ) and control groups ( n = 50 ) according to their stage of hypertension. There were two phases of treatment with 6 weeks in each phase for a total of 12 weeks. In the first phase, patients in the observation group received music-regulated laser therapy while the control group received drug therapy. In the second phase, the treatments were reversed, with the observation group receiving the drugs. The blood pressure and quality of life (QOL) of all the patients was evaluated after each phase. Results Before therapy there were no significant differences in average blood pressure or QOL between the groups. After the first phase, systolic blood pressure (SBP) and diastolic blood pressure (DBP) had been reduced significantly in both groups, but the decrease was significantly greater in the control group. The score on each item of the QOL evaluation was not significantly different between the two groups. After the second phase, blood pressure had decreased further in the observation group, but no significant change was observed in the control group, and there was no significant difference in blood pressure between two groups. The scores on each item of the QOL evaluation were not significantly different between the two groups, but average somatic symptoms, healthy and pleasant feelings, task perform-ance and life satisfaction were significantly ameliorated in both groups. Conclusions Music-regulated laser therapy can lower the blood pressure of mild and moderate PH patients effectively. Compared with antihyperten-sion drugs, music-regulated laser therapy provides a weaker effect in lowering blood pressure, but plays an e-quivalent role in improving the QOL of patients.

Objective To investigate the effect of Shanzha Xiaozhi capslue on intima-media thickness(IMT) and plaques score of carotid artery in patients with non-acute phase coronary heart disease and traditional Chinese medicine(TCM)syndrome of phlegm and blood stasis. Methods A prospective study was conducted to carry out a research on 102 patients with non-acute phase coronary heart disease and TCM syndrome of phlegm and blood stasis. They were randomly divided into two groups:a control group(50 cases)treated with conventional western medicine alone and a observation group(52 cases)which was treated by both conventional western medicine and Shanzha Xiaozhi capslue(the main TCM ingredients:Shanzha,Dahuang)0.7 g,3 times a day,the therapeutic course being 6 months in both groups. The cardiocerebral vascular incidences of the two groups were observed,in the mean time,the carotid artery IMT and plagues score were registered,the scores of phlegm stagnation syndrome and blood-stasis syndrome were measured,adverse reaction was observed and compared in both groups before and after treatment. Results After treatment,the occurrence of major adverse acute cardiovascular and cerebrovascular events in observation group were reduced significantly compared with those in the control group(5.77%vs. 20.00%,P<0.05). The IMT and plaques score of carotid artery and the scores of phlegm stagnation syndrome and blood-stasis syndrome were all decreased obviously compared to those before treatment,and the effect was more remarkable in the treatment group〔IMT of carotid artery(mm):0.80±0.13 vs. 0.95±0.12,the plaques score:1.35±0.65 vs. 1.75±0.88, phlegm syndrome score:20.98±6.42 vs. 35.55±9.22,blood-stasis syndrome score:23.23±5.12 vs. 28.95±6.38, P<0.05 or P<0.01〕. Abdominal pain appeared in 2 patients of observation group without other adverse reactions. Conclusion Shanzha Xiaozhi capsule can stabilize atherosclerotic plaque and reduce the occurrence of acute adverse cardiocerebral vascular events in patients with non-acute phase coronary heart disease and phlegm and blood stasis syndrome possibly by removing phlegm and blood stasis to decrease the IMT and plaques score of carotid artery.
