  • This study was performed to determine whether postprandial hypertriglyceridemia can affect the endothelial function. Endothelial function was assessed by flow-mediated endothelium-dependent brachial artery vasodilation (FMD) which was defined as percentile changes of diameter. Thirty one patients were enrolled in this study. The serum lipid profiles and FMD were measured at fasting, and after low fat and high fat meals. The serum triglycerides at 2 hours after a high fat meal were significantly increased compared to those measured at 2 hours after a low-fat meal and at fasting state (P<0.05). The FMD was transiently decreased (P<0.0001) from $11.4{\pm}3.2\%$ at fasting state to $6.5{\pm}2.5\%$ after a high-fat meal. The FMD was inversely related with postprandial hypertriglyceridemia (P<0.05). In conclusion, this study may suggest that postprandial hypertriglyceridemia causes endothelial dysfunction.

  • Let $\{(X_{ni}|1{\leq}i{\leq}n,\;n{\geq}1)\}$ be an array of rowwise negatively associated random variables. In this paper we discuss $n^{{\alpha}p-2}h(n)max_{1{\leq}k{\leq}n}|{\sum}_{i=1}^kX_{ni}|/n^{\alpha}{\rightarrow}0$ completely as $n{\rightarrow}{\infty}$ under not necessarily identically distributed with suitable conditions for ${\alpha}$>1/2, 0${\alpha}p{\geq}1$ and a slowly varying function h(x)>0 as $x{\rightarrow}{\infty}$. In addition, we obtain the complete convergence of moving average process based on negative association random variables which extends the result of Zhang (1996).

  • Purpose: This study was performed to identify and investigate the therapeutic effects of low-level laser (LLL) combined with a light-emitting diode (LED) on post-operative wound healing and functional recovery after hand orthopedic surgery. Methods: The study subjects were twenty patients who had passed the acute inflammatory phase after hand orthopedic surgery and were assigned equally to an experimental or a control group. Phototherapy was administered three times weekly for two weeks. Changes in wound length, edema, pain, and hand function were measured. Results: Significant differences in wound length, edema, pain, and hand function were observed between the experimental and control groups (p<0.05). However, no significant intergroup difference was observed (p>0.05). Nonetheless, a comparison of results showed changes in the experiment group over the two-week study period were significantly greater than in the control group (p<0.05). Conclusion: These findings show that combined LLL plus LED phototherapy positively influences post-operative hand rehabilitation.

  • Purpose: This study was conducted to identify the effects of home exercise programs and manual therapy on shoulder function and quality of life in patients with adhesive capsulitis. Methods: A total of 31 patients were enrolled in the study. All subjects were randomly assigned to a home exercise group (n=15) or a manual therapy group (n=16). Both groups performed each intervention program three times a week for four weeks. After four weeks, both groups performed a home exercise program continuously until week 12. Shoulder function was evaluated using the Korean Shoulder Scoring (KSS) system, while quality of life was evaluated using the WHO Quality of Life-BREF (WHOQOL-BREF) before and 4, 8, and 12 weeks after the intervention. Data were analyzed using two-way repeated measures analysis of variance (ANOVA). Results: There were significant differences in KSS before intervention and 4, 8, and 12 weeks after intervention for both the home exercise group and manual therapy group (p<0.001). There was also a significant difference in KSS at 4, 8, and 12 weeks when compared to the home exercise group and manual therapy group (p<0.001). Moreover, there was a significant difference in WHOQOL-BREF before and 4, 8, and 12 weeks after intervention in the home exercise group and manual therapy group (p<0.001). Conclusion: Home exercise and manual therapy improved shoulder function, but manual therapy led to a greater improvement in shoulder function better than home exercise. Home exercise and manual therapy improved quality of life, but there was no significant difference between groups.

  • Objective : Major complaints of carpal tunnel syndrome (CTS) are sensory components. However, motor deficit also impedes functional status of hand. Contrary to evaluation of sensory function, the objective, quantitative evaluation of median nerve motor function is not easy. The motor function of median was evaluated quantitatively using load cell and its correlation with findings of electrodiagnostic study (EDS) was evaluated. Methods : Objective motor function of median nerve was evaluated by load cell and personal computer-based measurement system. All of the measurement was done in patients diagnosed as having idiopathic CTS by clinical features and EDS findings. The strength of thumb abduction and index finger flexion was measured in each hand three times, and the average value was used to calculate thumb index ratio (TIR). The correlation of TIR with clinical, EDS, and ultrasonographic findings were evaluated. Results : The TIR was evaluated in 67 patients (119 hands). There were 14 males and 53 females, mean age were 57.6 years (range 28 to 81). The higher preoperative nerve conductive studies grade of the patients, the lower TIR was observed [p<0.001, analysis of variance (ANOVA)]. TIR of cases with thenar atrophy were significantly lower than those without (p<0.001, t-test). TIR were significantly lower in patients with severe median nerve swelling in ultrasonography (p=0.042, ANOVA). Conclusion : Measurements of median nerve motor function using load cell is a valuable evaluation tool in CTS. It might be helpful in detecting subclinical motor dysfunction before muscle atrophy develops.

  • Purpose: This study examined whether breathing exercises might increase the chest expansion and pulmonary function of stroke patients. Methods: Twenty four patients with stroke were assigned randomly into two groups: a combination of diaphragmatic resistive breathing and pursed-lip breathing exercise (CB) group (n=10) and control group (n=14). The CB group completed a 4-week program of diaphragmatic resistive breathing and pursed-lip breathing exercise. The subjects were assessed using the pre-test and post-test measurements of the chest expansion (length for resting, deep inspiration, deep expiration, deep expiration-inspiration) and pulmonary function (forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), vital capacity (VC), tidal volume (TV), expiratory reserve volume (ERV), inspiratory reserve volume (IRV)). Results: A comparison of the chest expansion between the pre and post tests revealed similar rest, deep inspiration, deep expiration, and deep expiration-inspiration lengths in the CB and control groups (p>0.05). A comparison of the pulmonary function between pre and post tests, revealed significant improvements in the FVC, FEV, PEF, VC, IRV, and ERV in the CB group (p<0.05). There was a significant difference in the FVC, FEV1, PEF, VC and IRV between the 2 groups (p<0.05). Conclusion: These findings suggest that breathing exercise should help improve the pulmonary function, such as the volume and capacity. This suggests that the pulmonary functions of stroke patients might be improved further by a continued respiratory exercise program.

  • Background: Reduced deformability of red blood cells (RBCs) may play an important role on the pathogenesis of chronic vascular complications of diabetes mellitus. However, available techniques for measuring RBC deformability often require washing process after each measurement, which is not optimal for day­to-day clinical use at point of care. The objectives of the present study are to develop a device and to delineate the correlation of impaired RBC deformability with diabetic nephropathy. Methods: We developed a disposable ektacytometry to measure RBC deformability, which adopted a laser diffraction technique and slit rheometry. The essential features of this design are its simplicity (ease of operation and no moving parts) and a disposable element which is in contact with the blood sample. We studied adult diabetic patients divided into three groups according to diabetic complications. Group I comprised 57 diabetic patients with normal renal function. Group II comprised 26 diabetic patients with chronic renal failure (CRF). Group III consisted of 30 diabetic subjects with end-stage renal disease (ESRD) on hemo-dialysis. According to the renal function for the diabetic groups, matched non-diabetic groups were served as control. Results: We found substantially impaired red blood cell deformability in those with normal renal function (group I) compared to non-diabetic control (P = 0.0005). As renal function decreases, an increased impairment in RBC deformability was found. Diabetic patients with chronic renal failure (group II) when compared to non-diabetic controls (CRF) had an apparently greater impairment in RBC deformability (P = 0.07). The non-diabetic cohort (CRF), on the other hand, manifested significant impairment in red blood cell deformability compared to healthy: control (P = 0.0001). Conclusions: The newly developed slit ektacytometer can measure the RBC deformability with ease and accuracy. In addition, progressive impairment in cell deformability is associated with renal function loss in all patients regardless of the presence or absence of diabetes. In diabetic patients, early impairment in RBC deformability appears in patients with normal renal function.

  • Purpose: To investigate the masticatory function of patients with different temporomandibular disorders (TMD) phenotypes, and to explore the risk factors for the masticatory function of TMD patients among multiple biopsychosocial variables using patient-reported outcomes (PROs). Methods: Clinical features and TMD diagnoses of 250 cases were investigated by reviewing medical records. Psychosocial factors were evaluated using four questionnaires representing pain severity and pain interference (Brief Pain Inventory), pain catastrophizing (Pain Catastrophizing Scale, PCS), psychological distress (Symptom Check List-90-Revised, SCL-90R) and kinesiophobia (Tampa Scale for Kinesiophobia for Temporomandibular Disorders, TSK-TMD). Masticatory function, as a dependent variable, was determined using the Jaw Functional Limitation Scale (JFLS). Kruskal-Wallis test and Spearman's rank correlation were used for analyses. Results: A total of 145 cases were included and classified into four subgroups including group 1: TMD with internal derangement without pain (n=14), group 2: TMD with muscle pain (n=32), group 3: TMD with joint pain (n=60) and group 4: TMD with muscle-joint combined pain (n=39). Pain severity (p=0.001) and interference (p=0.022) were the highest in group 2, but the mean global score of JFLS was the highest in group 3, followed by group 4, group 2, and group 1 (p=0.013). Pain severity, pain interference, the mean global score of PCS and the mean global score of TSK-TMD showed significant and moderate correlation with the mean global score of JFLS. All subdimensions and the global severity index of SCL-90R had significant, but weak correlations with all scores of JFLS. Conclusions: The results suggest that masticatory functional limitation depends on the TMD phenotypes. Among the various PROs, pain perception, pain catastrophizing and kinesiophobia seem to be more influential risk factors on jaw function than psychological distress, such as depression and anxiety.
