Objective To evaluate the intra-and inter-rater reliability of MyotonPRO for Achilles tendon properties measured. Methods Twenty healthy subjects were recruited to measure Achilles tendon properties using a novel hand-held Myoton-PRO device by two testers, one of the testers re-tested five days later. The reliability was assessed using in-tra-class correlation coefficient (ICC) and Bland-Altman analysis, and minimum detectable changes (MDC) was calculated. The Achilles tendon properties of the dominant or non-dominant leg was compared. The correlation between body mass and Achilles tendon properties was examined. Results The intra-rater reliabilities of Achilles tendon properties were ICCleft=0.884 and ICCright=0.904; the inter-rater reli-abilities were ICCleft=0.883 and ICCright=0.945. The MDC was 36.64 N/m. Bland-Altman plots showed good agreement. There was no significant difference in Achilles tendon properties between dominant and non-domi-nant legs (t<1.236, P>0.05). The body mass positively correlated with Achilles tendon properties (r>0.477, P<0.05). Conclusion The intra-and inter-rater reliabilities of MyotonPRO were good in measuring Achilles tendon properties in healthy subjects. No significant difference was found between dominant and non-dominant legs. The body mass positively correlated with Achilles tendon properties in healthy subjects.

BACKGROUNDThe relationship between monosymptomatic resting tremor (mRT) and Parkinson's disease (PD) remains controversial. In this study, we aimed to assess the function of presynaptic dopaminergic neurons in patients with mRT by dopamine transporter positron emission tomography (DAT-PET) and to evaluate the utility of clinical features or electrophysiological studies in differential diagnosis.

METHODSThirty-three consecutive patients with mRT were enrolled prospectively. The Unified Parkinson's Disease Rating Scale and electromyography were tested before DAT-PET. Striatal asymmetry index (SAI) was calculated, and a normal DAT-PET was defined as a SAI of <15%. Scans without evidence of dopaminergic deficits (SWEDDs) were diagnosed in patients with a subsequent normal DAT-PET and structural magnetic resonance imaging.

RESULTSTwenty-eight mRT patients with a significant reduction in uptake of DAT binding in the striatum were diagnosed with PD, while the remained 5 with a normal DAT-PET scan were SWEDDs. As for UPRDS, the dressing and hygiene score, walking in motor experiences of daily living (Part II) and motor examination (Part III) were significant different between two groups (P < 0.05 and P < 0.01, respectively). Bilateral tremor was more frequent in the SWEDDs group (P < 0.05). The frequency of resting tremor and the amplitude of postural tremor tend to be higher in the SWEDDs group (P = 0.08 and P = 0.05, respectively).

CONCLUSIONSmRT is heterogeneous in presynaptic nigrostriatal dopaminergic degeneration, which can be determined by DAT-PET brain imaging. Clinical and electrophysiological features may provide clues to distinguish PD from SWEDDs.

OBJECTIVETo evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program.

METHODSClinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out.

RESULTSThe 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05).

CONCLUSIONThe prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.

Objective To investigate the current conditions of water iodine,childrens'iodine nutrition and residents'edible circumstance of iodized salt in the villages with high iodine in drinking water and the adjacent three villages in Xiamen city of Fujian province.Methods Four natural villages of Qianbian,Donglian,Dazhong and Dongshan of Xiangan county were chosen as survey spots in 2008.In each village,one running water sample and all well water samples were collected to obtain the benchmark for each location.All children aged 7-13 year in the four villages underwent thyroid palpation and were selected to measure the urine iodine and the salt iodine.The water iodine and urine iodine were determined by As3+-Ce4+ catalytic spectrophotometry digestion,salt iodine was determined by direct titration.Results In four investigated villages,iodine of four running water samples were all 1.5μg/L.The range of 237 well water iodine samples was from 0.1 μg/L to 506.0 μg/L.There were 18.6% (44/237)specimens in which the well water iodine less than 10 μg/L,73.4%(174/237)between 10 μg/L and 150 μg/L and 8%(19/237)more than 150μg/L.The median of urinary iodine was 153.3 μg/L in 79 urine samples,which was 114%(9/79)more than 200μg/L and less than 300μg/L,12.7%(10/79)equal or more than 300 μg/L and less than 500μg/L,7.6%(6/79)equal or more than 500μg/L and less than 800 μg/L in all samples.Seventy-nine students were examined by palpation and the total goiter rate of children measured was 11.4% (9/79).Seventy-one samples of iodine salt were detected and the coverage rate of iodized salt was 77.5%(55/71).Conclusions The well water iodine contents have a wide distribution in the investigated villages.We should enhance the community awareness by educating them on the damage of iodine excess and iodine deficiency.

UNLABELLED: Abstract: OBJECTIVE: To investigate the bacterial succession on rat carcasses and to evaluate the use of bacterial succession for postmortem interval (PMI) estimation. METHODS: Adult female SD rat remains were placed in carton boxes. The bacterial colonization of circumocular skin, mouth and vagina was collected to be identified using culture-dependent biochemical methods. The changes in community composition were regularly documented. RESULTS: The bacterial succession in three habitats showed that Staphylococcus and Neisseria were predominated in early PMI, especially Staphylococcus aureus and Neisseria lactamica in 6 hours after death. Lactobacillus casei developed on the 3-4 days regularly, and kept stable at a certain level in late PMI. CONCLUSION The involvement of normal and putrefactive bacteria in three body habitats of rat remains can be used for PMI estimation.
