[Purpose] To investigate the relation between isotonic leg extension strength (ILES) and the prevalence of metabolic syndrome (MS) in Japanese male adults.[Methods] This cross-sectional study included 395 Japanese men. Metabolic syndrome was determined according to the criteria of International Diabetes Federation (IDF), Japan Society for the Study of Obesity (JASSO), or National Cholesterol Education Program's Adults Treatment Panel III (NCEP-ATPIII). Muscular strength was measured on a horizontal dynamometer. Subjects were divided into tertile levels according to ILES (watts/kg). Multiple logistic regression analysis was used to examine the relation between ILES levels and the prevalence of MS.[Results] The prevalence of MS were 14.4% (IDF), 17.0%(JASSO), and 20.0% (NCEP-ATPIII). After adjustment for confounding factors, the odd's ratios (95% confidence interval) of MS (IDF) compared with the lowest ILES level were 0.90 (0.48-1.68) and 0.31 (0.13-0.64) in the middle and high levels of ILES (p for trend=0.03). The association between the level of ILES and the prevalence of MS by JASSO and NCEP-ATPIIIcriteria were similar.[Conclusion] The prevalence of MS was associated with the level of ILES.

Objective To analyze the differential expression of D2 and D3 alternative splicing sites of human kinectin in human hepatocellular carcinoma (HCC) tissues, adjacent non-cancerous tissues and normal liver tissues, and to investigate a possible relationship between alternative splicing sites of kinectin and hepatocarcinogenesis. Methods The cDNA was obtained by RT-PCR in 45 coupled HCC cancerous and adjacent tissues, and 10 normal liver tissues. The difference in the expression of D2 and D3 alternative splicing sites in cDNA was examined by semi-quantitative PCR, and statistical analysis was performed. Results The ratio of D2L (long segment contains of the D2 region)/D2S (short segment that does not contain a D2 zone) in hepatocellular cancerous tissues was 2.709 ± 1.025, the ratio of D2L/D2S in adjacent non-cancerous tissues was 1.564 ± 0.357, and the ratio of D2L/D2S in normal liver tissues was 1.507 ± 0.499. The differences were statistically significant (F=29.698, P<0.05);the ratio of D2L/D2S in hepatocellular cancerous tissues was higher than that of adjacent non-cancerous tissues and normal liver tissues (P<0.05). The ratio of D3L (long segment contains of the D3 region)/D3S (short segment that does not contain a D3 zone) in hepatocellular cancerous tissues was 1.232 ± 0.041, the ratio of D3L/D3S in adjacent non-cancerous tissues was 1.156 ± 0.309, and the ratio of D3L/D3S in normal liver tissues was 1.282 ± 0.343. The ratio of D3L/D3S was not significantly different among hepatocellular cancerous tissues, adjacent non-cancerous tissues and normal liver tissues (F = 0.989, P > 0.05). Conclusion Variant containing D2 is over expressed in cancerous tissues and this alteration may be tumor associated.

Coffee administration has been shown to increase maximum voluntary contraction and muscular endurance. However, no study has addressed the association between daily consumption of coffee with muscular function. This cross sectional study aimed to investigate the association between frequency of coffee consumption (CC) in daily life and muscle strength among a population of working adult men. This cross sectional study included men (n = 516, mean age: 47.1) who participated in an annual health examination conducted in Sendai. The monthly frequency of coffee consumed was reported by a brief-type self-administered dietary history questionnaire. Leg extension power (LEP) was measured as an index of muscle strength. Subjects were divided into tertile levels according to CC. Analysis of covariance was used to examine the relation between the tertile levels of CC and LEP. After adjustment for potential confounders (including all lifestyle factors), the adjusted means (95% confidence interval) of LEP across the tertiles of CC were 17.4 (16.6 - 18.1) for the lowest tertile, 17.9 (17.4 - 18.5) for the mid tertile, and 18.9 (18.3 - 19.5) for the highest tertile (p for trend = 0.007). Higher frequency of monthly coffee consumption was associated with higher muscle strength.

In order to effectively manage the atrial fibrillation patients, West China Hospital has established an integrated general-specialty management model within medical consortium. This model takes the atrial fibrillation-stroke integrated management outpatient clinic as the platform, combines general practice and specialty to provide standardized care for atrial fibrillation patients. The model was characterized by primary diagnosis, two-way referral, up and down linkage, and differential management for acute and chronic conditions. This article, taking West China Hospital as an example, introduces the integrated team of cardiologists and general practitioners in the tertiary hospital with general practitioners in the community, and the preliminary accomplishment in the management of atrial fibrillation within the medical consortium. It would provide a reference for the long-range management of atrial fibrillation in other provinces and cities.

OBJECTIVE
To investigate the transfer and diffusion of berberine hydrochloride(BBH), the main active component of Coptis and Phellodenticum in the system of carboxymethyl chitosan(CMCS)-sodium alginate(SA).
METHODS
CMCS and SA were stirred in a certain proportion, and D-gluconolactone(GDL) was added to form polyelectrolyte hydrogel. Rheometer was used to study the rheological properties of CMCS-SA hydrogel, including the elastic modulus G′ and the viscous modulus G′′. A BBH diffusion model for CMCS-SA hydrogel was designed, and the relevant rules of BBH permeation through CMCS-SA polyelectrolyte hydrogel were observed by UV-VIS.
RESULTS
The elastic modulus G′ of the hydrogel was measured when the ratio of CMCS to SA was 3∶1, 2∶1, 1∶1, 1∶2, and 1∶3. When the ratio of CMCS to SA was 1∶1, G′ was the highest, and the crosslinking strength of the hydrogel was the highest. The cumulative amount of BBH transfer was measured by the BBH transfer model, and the diffusion of BBH in CMCS-SA hydrogel was fitted as the skeleton dissolution by Peppas equation, indicating that BBH dissociation and the transfer efficiency increased as the amino group of CMCS decreased or the carboxyl group of SA increased. The elastic modulus G′ of CMCS-SA hydrogel increased with the increase of GDL content. The reason was that the binding force between CMCS and SA molecules gradually increased with the decrease of pH, and the crosslinking degree of the hydrogel was enhanced. When ratio of fixed CMCS to SA was 1∶1 and the GDL content was 0.15 g·mL−1, the formability of CMCS-SA hydrogel was good. In addition, when BBH was transferred in hydrogel with different concentrations of GDL, the transfer efficiency increased with the increase of GDL content. When BBH was delivered in different thickness hydrogel, the delivery efficiency of CMCS-SA hydrogel increased with the decrease of thickness.
CONCLUSION
The CMCS-SA hydrogel system, as a potential drug carrier for traditional Chinese medicine extracts such as BBH, is expected to serve as a gel carrier for transdermal drug delivery.
