OBJECTIVETo study the relationship between ultrasonic bone mineral density (BMD) of calcaneus and age, height, and body weight, and to establish the normal reference value for stiffness index (SI) of healthy subjects in Guangxi autonomous region and provide scientific foundation for the diagnosis and prevention of osteoporosis.

METHODSSI of calcaneus in 1 816 healthy adults aged 11-90 years (775 men, 1 041 women) were measured with quantitative ultrasound. According to their ages, all the men and women were divided into 13 groups by 5-year age group.

RESULTSSI reached peak values in 21-25 year group in men (range: 111.45 +/- 21.19) and in 16-20 year group in women (range: 101.26 +/- 17.51). Then the SI value began to decline with aging. The SI featured by a typical dual-peak curve in women and the decrease rate of SI was faster in women than in men over 61 years. Multivariate linear regression analysis showed significantly negative correlation between SI and age (P < 0.001), positive correlation between SI and body weight (P < 0.05 for men; P < 0.01 for women), and positive correlation between SI and height in women (P < 0.01).

CONCLUSIONSI correlates with age, height, and weight. The acquired SI value may provide a reference for the diagnosis of osteoporosis.

BACKGROUND: The size of artificial disc is not exactly identical to cervical vertebral endplate. However, the effect of implant size on cervical disc replacement has not yet been clearly identified. OBJECTIVE: To evaluate the effect of Bryan disc size on cervical artificial disc replacement. METHODS: Totally 71 patients with cervical degenerative disease underwent single-level Bryan disc replacement from December 2003 to December 2007 were enrolled. The average age was (45.90±8.12) years old, and all patients were followed up for more than 10 years. The artificial disc size was measured using lateral X-ray films, and expressed as (Bryan artificial disc's footprint sagittal diameter×2) / (upper endplate sagittal diameter + lower endplate's sagittal diameter)×100%. X-ray films were photographed to measure motion range of the treated segment before surgery, 3 months after surgery, and during final follow-up. Clinical outcomes, including Japanese Orthopaedic Association score, Neck Disability Index and Odom's scores, were evaluated before and after operation. Observational indexes of different disc sizes (≥95% and <95% groups) were compared and analyzed. RESULTS AND CONCLUSION: (1) There were 49 patients in the ≥95% group and 22 patients in the <95% group. (2) At 3-month follow-up, range of motion was significantly smaller in the <95% group than in the ≥95% group (P < 0.01). At the final follow-up, range of motion was significantly smaller in the <95% group than in the ≥95% group (P < 0.05). (3) At final follow-up, improvement rate of Japanese Orthopaedic Association score was (70.65±32.58)% in the <95% group and (68.83±38.85)% in the ≥95% group, and no significant difference was detected between the two groups (P > 0.05). (4) At final follow-up, Neck Disability Index decreased by (10.82±7.50)% in the <95% group, and (12.61±8.51)% in the ≥95% group, and no significant difference was detected between the two groups (P > 0.05). (5) At final follow-up, Odem's score results showed excellent in 10 cases (45%), good in 9 cases (41%) and average in 3 cases (14%) in the <95% group; and excellent in 26 cases (53%), good in 20 cases (41%) and average in 3 cases (6%) in the ≥95% group, and no significant difference was detected between the two groups (P > 0.05). (6) Results suggest that different sizes of artificial disc replacement have obtained good functional recovery, but small artificial disc may impact the range of motion. We should try to avoid placing the artificial disc smaller than 95%.

OBJECTIVETo study the changes of serum total calcium (Ca) and inorganic phosphate (P) levels during children growth and related factors.

METHODSUsing a stratified-multi-steps-cluster sampling method, we selected 2,342 healthy children aged 10-18 years from urban and suburban areas of Beijing from September 2001 to December 2001 to test the levels of serum Ca and P. Their meal status was also surveyed to analyse the correlation of the leves of serum Ca and P with sex, age, height, weight, and diet on statistic basis.

RESULTSThe Ca levels of Beijing children were (2.39 +/- 0.12) mmol/L, which had a positive correlation with age, height, and weight (P < 0.01). The Ca levels of female children were somewhat higher than those of male [male, (2.38 +/- 0.12) mmol/L; female, (2.39 +/- 0.12) mmol/L; P < 0.05]. The Ca levels of urban children were significantly higher than those of suburban children [urban, (2.40 +/- 0.13) mmol/L; suburban, (2.37 +/- 0.10) mmol/L; P < 0.001]. The P levels of Beijing children were (1.39 +/- 0.18) mmol/L, which had a negative correlation with age, height, and weight (P < 0.01). The P levels of male children were significantly higher than those of female [male, (1.43 +/- 0.18) mmol/L; female, (1.36 +/- 0.17) mmol/L; P < 0.001]. The P levels of urban children were significant higher than those of suburban children [urban, (1.41 +/- 0.19) mmol/L; suburban, (1.38 +/- 0.16) mmol/L; P < 0.001]. The Ca levels of Beijing children had a negative correlation with P levels (r=-0.141, P < 0.01). [Ca] x [P] (mmol/L) of Beijing children were 3.32 +/- 0.44. The value of [Ca] x [P] reached peak by 3.45 +/- 0.46 when Beijing children were of 13-14 years old, and then the value declined with increasing age.

CONCLUSIONThe levels of serum Ca and P correlates with sex, age, growth, and diet. The level of serum Ca goes up while P goes down during the children growth.

OBJECTIVETo examine the effect of body fat mass and fat distribution on pulmonary ventilatory function among the adult females.

METHODSBased on the multistage cluster sampling principal, we selected 935 healthy adult females with ages of 19-81 years old in Heilongjiang province to conduct the study. Every 10-years old as a age group. Firstly obtain the basic situation through the questionnaire survey, and then measure the height, body weight, waistline, hip circumference, body composition and lung function. FVC, FEV1, PEF, FEF25%, FEF 50%, FEF 75% and MMEF were determined. This study also examined the relationships between percentage body fat (PBF), waist-hip ratio (WHR) and FVC, FEV1, PEF, FEF25%, FEF 50%, FEF 75%, MMEF.

RESULTSPBF of subjects with ages of 19 - 29 years old and over 60 years old were (16.89 ± 5.34)% and (24.39 ± 6.83)%, WHR were 0.77 ± 0.05 and 0.88 ± 0.06, respectively. PBF and WHR tended to increase with age (F = 50.11, P value < 0.01). PBF obesity rates of subjects with ages of 19 - 29 years old and over 60 years old were 3.23% (7/217) and 43.75% (28/64), WHR obesity rates were 19.35% (42/217) and 85.94% (55/64) respectively. PBF obesity rate and WHR obesity rate tended to increase with age (χ(2) = 161.66, P value < 0.01; χ(2) = 159.61, P value < 0.01). PBF obesity groups compared with the normal groups, the former pulmonary ventilation function reduced significantly, of which FEF 50%, FEF 75% and MMEF decreased 2.61%, 19.44%, 10.28%, respectively. WHR obesity groups compared with the normal groups, the former pulmonary ventilation function reduced significantly, of which FEF 50%, FEF 75% and MMEF decreased 7.61%, 23.15%, 12.04%. After adjustment of age, height and body mass index (BMI), PBF was negatively correlated with FVC, FEV1, PEF and FEF25% (r values were -0.14, -0.14, -0.07, -0.07, respectively, all P value s < 0.05); WHR was negatively correlated with FEV1 (r value was -0.07, P value < 0.05) after adjustment of age, height and BMI.

CONCLUSIONPBF augmentation and abdominal obesity among adult females may be the risk factors of pulmonary function impairment.

OBJECTIVETo assess objectively the efficacy of migraine without aura treated by comprehensive auricular acupuncture.

METHODSNinty patients of migraine without aura from three centers were selected as the observation subjects. Thirty cases from each center were treated with the comprehensive auricular acupuncture. This therapy included the retroauricular venous bleeding on the ears, the autologous blood injection at Fengchi (GB 20) and Yanglingquan (GB 34) and bleeding at the Nie (temporal), Zhen (occiput), Yidan (pancreas), Shenmen, Pizhixia (subcortex) and Neifenmi (endocrine) of auricular point. The therapy was applied once every 7-10 days. The continuous 3 treatments made one session.

RESULTSAt the end of one session for the patients in three centers, the headache scores were reduced apparently as compared with those before treatment (all P< 0.05). There was no statistically significant difference in comparison among three centers (all P>0.05). The clinical total effective rates were 93.3% (28/30), 90.0% (27/30) and 93.3% (28/30) in three centers separately. There was no obvious difference in the efficacy in comparison among three centers (P>0.05).

CONCLUSIONThe comprehensive auricular acupuncture reduces apparently the headache score for migraine without aura and relieves the clinical symptoms of migraine. It is the simple and effective therapy for migraine without aura.

Aliquots of venous blood from healthy donor were collected in plastic blood storage bags with ACD, GMA or antioxidant solution (superoxide dismutase, SOD), respectively, and stored at 4 degrees C. After storage for varying periods, the parameters of the blood were detected in the blood samples. Results showed that the parameters of the blood stored at 4 degrees C for 75 days in SOD group were following: the recovery of RBC-Hb was 87.2%, plasma-Hb (mg/L) was 193.2, P50 (mmHg) was 34.0 (normal value was 33.1); deformability (DImax) was 0.2413 (74.3% of normal value). There was no evident hemolysis, color change, air bubble and clots. It was concluded that human RBC stored at 4 degrees C for 75 days with SOD solution, recovery of levels of RBC-Hb and plasma-Hb were accorded with the requirements of "Basic Demands of Blood Station" in China.

AIMTo investigate the mechanism of protective effect of SOD (superoxide dismutase) on damage of RBCs stored at 4 degrees C, the studies of erythrocyte glucose and energy metabolism were performed.

METHODSwhole blood collected from healthy donors and stored at 4 degrees C in ACD, GMA and SOD solutions. Before and post storage, some parameters were assayed. Standard methods were used for the in vitro tests. The 24-hour in vivo recoveries were measured by FTTC (Fluorescein 5-isothiocyanate) from SIGMA Company.

RESULTSAll parameters of red blood cell glucolysis rate without oxygen condition, ATP, PK (pyruvic kinase) and 24 h recoveries level were 86.2%, 56.4%, 64.3% and 86.2% of normal respectively stored in SOD solution at 4 degrees C for 75 days, distinctly more than in ACD and GMA groups at 75 days stored. The 24 h recovery at 75d in group SOD was near the recovery at 42d in group GMA.

CONCLUSIONWhole blood in SOD solution can be stored satisfactorily for 75 days at 4 degrees C, and furnished theoretical evidence for RBCs survival.
