Objective To investigate the effect of isokinetic training on stiff knees after fracture arrest. Methods 38 fracture patients were divided into observation group (n=19) and control group (n=19) by the medical number. Both 2 groups received the Chinese herbs fumigation and joint mobilization. Besides, the observation group received the isokinetic training, while the control group received the instrument training. The range of motion (ROM), maximum peak torque (PT), peak torque/body weight (PT/BW), average power (AP), and hamstrings/quadriceps (H/Q) were tested before and 16 weeks after training. Results The flexion, straightness and flexion radian became significantly better after training. The flexion and the increase of the flexion radian were significantly better in observation group than in control group after training. All indexes of the isokinetic test significantly improved after training (P<0.001) except H/Q (P>0.05). ROM、PT、PT/BW and AP of the knees joint were significantly better in the observation group than in the control group (P<0.001) after training, while there was no significant difference in H/Q between 2 groups (P>0.05) after training. Conclusion Isokinetic training can promote recovery of stiff knees of femur fracture.

Objective To investigate the difference of apparent diffusion coefficients (ADCs) changes in three major salivary glands after gustatory stimulation using two different stimuli. Methods Thirty healthy volunteers were examined with a 1.5 T MR unit. A diffusion-weighted MR imaging (MR DWI) sequence was performed once at rest and continuously repeated 13 times after gustatory stimulation using a commercially available lemon juice and vitamin C tablets in the same volunteer by using self-controlled method. The subsequence of two stimuli was random. In addition, the salivary flow rates at rest and after stimulation were measured. Characteristics and differences in ADCs curves of three salivary glands before and after stimulation between two stimuli were analyzed. Comparison of maximum ADCs, maximum ADCs increase rates (IRs) and times to maximum ADCs(Tmax) between two stimuli was performed by using independent-samples t test. Correlation analysis between rest salivary flow rates and rest ADCs, the maximum salivary flow rates and ADCs after stimulation, the maximum salivary flow IRs and ADC IRs after stimulation were performed by using Pearson correlation test. Results In lemon juice stimulation group, the mean ADCs mostly showed a steady increase to peak values during the first DW MRI scan after stimulation in all glands, followed by a gradually decrease fluctuating slightly around the baseline values. In vitamin C stimulation group, the mean ADCs were significantly increased in all glands during the first DW MRI scan after stimulation, followed by a gradual upward trend till peak values. In lemon juice stimulation group, the mean Tmax of submandibular and sublingual glands[(184±122)s, (345±232)s, respectively] were significantly earlier than those[(454 ± 301)s, (528 ± 297)s, respectively] in vitamin C stimulation group (t=-3.517 and-2.548 respectively, P<0.01 for all). The mean maximum ADCs of three glands in lemon juice stimulation group[(1.05 ± 0.12) × 10-3 mm2/s, (1.22 ± 0.10) × 10-3 mm2/s and (1.26 ± 0.21) × 10-3 mm2/s, respectively] were all lower than those in vitamin C stimulation group[(1.13±0.13) ×10-3 mm2/s, (1.32±0.25) × 10-3 mm2/s and (1.57 ± 0.36) × 10-3 mm2/s, respectively], and the differences in parotid and sublingual glands between two groups were significant(t=-2.894 and-3.681 respectively, P<0.01 for all). The mean maximum ADC IRs of three glands in lemon juice stimulation group[(11.35±4.07)%, (8.81±5.40)%, (34.08±21.66)%, respectively] were significantly lower than those[(17.80 ± 12.72)%, (18.16 ± 18.93)%, (67.49 ± 46.04)% , respectively] in vitamin C stimulation group (t=-2.252,-2.330 and-3.432 respectively, P<0.05 for all) . In two groups, the mean maximum ADC IRs of parotid and submandibular gland were all significantly lower than sublingual gland (t=-5.994 and-6.443 respectively, P<0.01 for all). No correlation was observed between ADCs and salivary flow rates, ADC IRs and salivary flow rate IRs in two groups (P>0.05). Conclusion MR DWI with transient stimulation using lemon juice is more stable for evaluating the physiologic changes of salivary glands in vivo.

Objectives: To evaluate the effect and safety of 14-day continuous subcutaneous insulin infusion (CSII) in type 2 diabetes patients with heart diseases.
Methods: A total of 22 consecutive type 2 diabetes patients (history ≤ 5 years) with heart diseases treated in our hospital from 2011-03 to 2013-08 were studied. There were 20 male, and the with the mean age of patieuts (48.15 ± 9.80) years, all patients without standard hypoglycemic treatment before admission. The patients received 14-day CSII for enhanced treatment and the blood glucose level, insulin function and insulin sensitivity were compared before and after the treatment.
Results: After CSII treatment, the blood glucose level was obviously decreased, fasting blood glucose (FBG) and postprandial blood glucose at 30, 60 and 120 min were improved, all P<0.001. The C peptide level was higher at 60 and 120 min alter treatweut as 2.73 (1.05-7.05)ng/ml vs 3.84 (1.22-63.39)ng/ml, P=0.004 and 3.34 (1.42-9.61)ng/ml vs 6.27 (0.93-47.39)ng/ml, P=0.004. The insulin sensitivity was improved as -1.89 ± 0.29 vs -1.70±0.31, P=0.008. With CSII treatment, there were 22.73% patients (5/22) at remission by controlling the diet and excise and 77.27% (17/22) with continuing medication. The patients were followed-up for (12.4 ± 8.5) months, there were 4/5 patients with euglycemia, 1/5 with increase blood sugar and received medication at 2 months after discharge, the rest 17 patients remained oral hypoglycemic medication.
Conclusion: CSII may quickly relieve glucotoxicity and improve insulin sensitivity in type 2 diabetes patients with heart diseases. Some patients may alleviate drug burden in clinical practice.

OBJECTIVEThe effect of the gene polymorphism for the key enzyme's folacin metabolism pathway on plasmatic homocysteine (Hcy) levels in fertile woman was observed.

METHODSThe subjects were from Shaoxing City, Jiangsu province in 2012, the selection criteria for the women of childbearing age were between 20-45 years old, with an average age of 28.2 (95%CI:27.8-28.6) years old. Sample collection continued uninterrupted lasted seven days, a total of 535 samples were collected, venous blood with EDTA addition or sodium citrate to anticoagulant. After separation, the blood cells and blood plasma were cryopreserved. DNA was extracted using spin column method. All the samples were selected for the gene polymorphism testing of the key enzyme's on folate metabolism and monitoring of plasmatic Hcy level.

RESULTSEight single nucleotide polymorphism (SNP) sites of methylenetetrahydrofolate reductase gene (MTHFR) , methionine synthase gene (MS) , synthetic methionine reductase gene (MSR) and cystathionine β synthase gene (CBS) were detected. It was found the genotype AA of the SNP sites-rs1801131 would result higher plasmatic Hcy levels (8.99 µmol/L) than the genotypes CC (7.81 µmol/L) and CA(8.38 µmol/L) (P < 0.01) . Similarly, the genotype TT of the SNP sites-rs1801133 was significantly responded to the increasing of Hcy levels (11.10 µmol/L) than the genotype CC (8.15 µmol/L) and CT (8.45 µmol/L), (P < 0.01) . The two sites of genotype combination of AA-TT could also result in the significant increase of Hcy levels (11.02 µmol/L) than other combined genotypes (genotypes CC-CC, CA-CC, CA-CT, AA-CC, AA-CT), especially the genotype CC-CC. And the risk factor was 1.41 (95CI:1.20-1.66) times over the genotype CC-CC.

CONCLUSIONThe gene mutations of two SNP sites rs1801131 and rs1801133 in MTHFR would increase Hcy levels.
