ABSTRACT
<p><b>BACKGROUND</b>Currently, treatment of symptomatic polycystic liver disease (PLD) is still a challenging problem, especially for these patients who are not feasible for surgery. Minimally invasive options such as laparoscopic fenestration and percutaneous cyst aspiration with sclerotherapy demonstrated disappointing results due to multiple lesions. Because the cysts in PLD are mostly supplied from hepatic arteries but not from portal veins, transcatheter arterial embolization (TAE) of the hepatic artery branches that supply the major hepatic cysts can lead to shrinkage of the cyst and liver size, relieve symptoms, and improve nutritional status. This study aimed to evaluate the effectiveness of TAE with a mixture of N-butyl-2-cyanoacrylate (NBCA) and iodized oil for patients with severe symptomatic PLD during a more than 2-year follow-up.</p><p><b>METHODS</b>Institutional review board had approved this study. Written informed consent was obtained from all patients. From February 2007 to December 2014, twenty-three patients (20 women and 3 men; mean age, 49.0 ± 14.5 years) infeasible for surgical treatments underwent TAE. Changes in the abdominal circumferences, volumes of intrahepatic cysts, hepatic parenchyma volume, and whole liver, clinical symptoms, laboratory data, and complications were evaluated after TAE.</p><p><b>RESULTS</b>Technical success was achieved in all cases. No procedure-related major complications occurred. The median follow-up period after TAE was 48.5 months (interquartile range, 30.0-72.0 months). PLD-related severe symptoms were improved remarkably in 86% of the treated patients; TAE failed to benefit in four patients (four patients did not benefit from TAE). The mean maximum abdominal circumference decreased significantly from 106.0 ± 8.0 cm to 87.0 ± 15.0 cm (P = 0.021). The mean intrahepatic cystic volume reduction rates compared with pre-TAE were 36% at 12 months, 37% at 24 months, and 38% at 36 months after TAE (P < 0.05). The mean liver volume reduction rates were 32% at 12 months, 31% at 24 months, and 33% at 36 months (P < 0.05).</p><p><b>CONCLUSIONS</b>TAE with the mixture of NBCA and iodized oil appears to be a safe and effective treatment method for patients with symptomatic PLD, especially for those who are not good candidates for surgical treatments, to improve both hepatic volume and hepatic cysts volume.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To explore the crew and passengers' comfort on the Shijiazhuang-Taiyuan passenger dedicated line and physical factors, such as air pressure, noise, wind speed.</p><p><b>METHODS</b>Comfort investigation of all the crew (n = 244) and passengers (n = 377) on the Shijiazhuang-Taiyuan passenger dedicated line at speed of 250 km/h and 200 km/h and the detection of the air pressure, noise and wind speed were performed in 2011.</p><p><b>RESULTS</b>Significantly higher ratio of comfortable feeling, lower ratio of seriously discomfortable feeling were observed in crew and passengers at 200 km/h compared with those at 250 km/h (P < 0.05), as well as rapid disappearance of discomfortable feeling in crew (P < 0.05) and significantly higher ratio of lightly discomfortable feeling and lower ratios of tinnitus and eardrum discomfort induced by air pressure and noise in passengers at 200 km/h. No significant difference was observed in ear discomfort induced by air pressure and noise among crew, and the duration of disappearance of discomfortable feeling among passengers between 200 km/h and 250 km/h. The noise in carriages exceeded the related standard when the high-speed train passing through the tunnels.</p><p><b>CONCLUSION</b>The individuals feel more comfortable at 200 km/h than 250 km/h in this line., which may be related with rapid variation of wind speed and noise when the train passes through the tunnels with high speed.</p>

<p><b>BACKGROUND</b>On the afternoon of May 12, 2008, a 8.0-magnitude earthquake hit Sichuan Province, a mountainous region in Western China, killing about 70 000 people and leaving over 18 000 missing. What about the survivors motor functions and activities of daily living (ADL) capacity, especially for fractures? We need the data to guide the rehabilitation for the seismic wounded and it's important to collect the data for the future. We study the survivors to understand the motor functions and ADL capacity of patients with fractures sustained in the Wenchuan earthquake, to provide a basis for rehabilitation and treatment.</p><p><b>METHODS</b>We used the Manual Muscle Testing method to evaluate muscle strength, the joint angle scale to measure joint range of motion (ROM), and the Barthel index to evaluate the activities of daily living status. SPSS 13.0 software was used to analyze the data and the results were tested using one-way analysis of variance (ANOVA).</p><p><b>RESULTS</b>The number of seismic wounded amounted to 487; 81.1% of patients had fractures. Most of the injured had fractures in multiple regions (53.9% of all fracture patients), followed by fractures of the upper limb (34.0% of patients); cranial fractures were rare (2.3%). Totally 82.0% had restricted range of motion, 23.5% had decreased muscle force, and 72.2% of the patients had restricted activities of daily living capacities. With time the activities of daily living capacity of female increased (P < 0.05), compared with the male fracture patients who did not show any relative improvement (P > 0.05). The difference between the patients' ages and ADL capacities did not reach statistical significance (P > 0.05), nor was there a significant difference between their ages and the numbers of days in hospital (P > 0.05).</p><p><b>CONCLUSIONS</b>Fractures were the main issue in the seismic wounded, many of them had reductions in the ROM, muscle force and ADL capacities. The physicians involved in rehabilitation should pay greater attention to muscle force exercises, joint mobilization, and occupational therapy during the early phases post disaster.</p>

<p><b>OBJECTIVE</b>To evaluate the efficacy and potential renal impairment of one-year combination therapy de novo of adefovir dipivoxil (ADV) and lamivudine (LMV) for decompensated cirrhosis related to HBV.</p><p><b>METHODS</b>A total of 36 patients with decompensated cirrhosis related to HBV, nobody had nucleos(t)ide analogs (NAs) treatment history, were recruited and were divided into two group (control group and observation group) randomly. A monotherapy of LMV (100 mg per day) was selected to individuals in control group (n = 18), in contrast, a combination therapy de novo of ADV (10 mg per day) and LMV (100 mg per day) was applied to those in observation group (n = 18). Basic approaches including liver protection, symptom-driven intervention, and supporting therapy, were given to all of the individuals. A course of one year was applied to all. Liver function, Child-Pugh score, serum creatinine (sCr) level, virological response (VR) rate, and virological breakthrough rate were observed pro- and post- treatment, differences between the two populations were analysed statistically.</p><p><b>RESULTS</b>(1) The averages of gender, age, HBeAg status, HBV viral load, sCr level, and Child-Pugh score were all compatible in the two groups at baseline (P > 0.05 for all). (2) At the endpoint of treatment, none of deaths was reported. Comparing with the status before treatment in each group itself, liver function, Child-Pugh score, and viral load were improved statistically (P < 0.01 for all), especially in observed group (P < 0.01 for all variables, vs control group), as for VR rate, result is significant superior to that of control group too (88.89% vs 66.67% , P < 0.05). (3) Virological breakthrough occurred to none in observed group and three cases (16.67%) in control group, all of them were confirmed to be rtM204V variant in the following detection of direct sequencing. (4) Elevated level of sCr didn't arised at the end of treatment in two groups.</p><p><b>CONCLUSION</b>Present study reveals that in populations with decompensated cirrhosis related to HBV, one-year combination therapy de novo of ADV and LMV is superior to monotherapy of LMV, and the renal safety is favorable within one year.</p>
