Objective To evaluate the effect of intraperitoneal water soluble lipopolymer (WSLP)/ N-methyl-D-aspartate receptor subunit 2B (NR2B) siRNA compound on the neuropathic pain (NP) in rats.Methods Eighty-four healthy male Sprague-Dawley rats,aged 6 weeks,weighing 180-220 g,were randomly divided into 7 groups (n =12 each) using a random number table:control group (group C),sham operation group (group S),NP group,WSLP/NR2B siRNA group (siWSLP group),WSLP/negative control siRNA group (ncWSLP group),PEI/NR2B siRNA group (PEI group) and WSLP group (WSLP group).NP was produced by ligation of the left L5 spinal nerve.In group S,the left L5 spinal nerve was only exposed,but not ligated.In group C,the rats underwent no treatment.Groups siWSLP,ncWSLP,PEI and WSLP received single intraperitoneal injection of WSLP/NR2B siRNA,WSLP/negative control siRNA,PEI/NR2B siRNA and WSLP compound 2 ml,respectively,at 10 days after NP.At 1 day before operation,7 days after operation,and 3,7,14 and 21 days after intraperitoneal injection,6 rats in each group were chosen randomly to measure mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL).At 3 days after intraperitoneal injection,the left 6 rats in each group were sacrificed and the spinal cord was removed for detection of NP2B mRNA expression (using PCR) and NR2B expression (by Western blot).Results Compared with group C,MWT was significantly decreased,and TWL was shortened on 7 days after operation and 3,7 and 21 days after intraperitoneal injection,and the expression of NR2B mRNA and protein was down-regulated on 3 days after administration in the other groups.Compared with group NP,MWT was significantly increased,and TWL was prolonged on day 3 and 7 after intraperitoneal injection,and the expression of NR2B mRNA and protein was down-regulated on day 3 after administration in siWSLP group.Conclusion Intraperitoneal WSLP/NR2B siRNA compound can effectively relieve the NP in rats.

Objective To determine the normal position of the fetal conus medullaris and assess its clinical significance.Methods A total of 550 singleton pregnant women who were examined by fetal ultrasonography in the Department of Ultrasound at the Second Hospital of Fujian Medical University from June 1, 2013 to September 31, 2014 were included.Inclusion criteria were pregnancies with regular menstruation cycle and known last menstrual period, gestational age (GA) confirmed by ultrasonographic examinations, and neonate abnormality excluded by pediatrician after born.Routine obstetric ultrasound examinations were performed to measure the biparietal diameter (BPD), femur length (FL), head circumference (HC) and abdominal circumference (AC).The conus distance (CD) was determined by measuring the distance between the distal end of the conus medullaris and the caudal end of the last vertebra.The average value was calculated for each group according to GA.Fifty normal fetuses were randomly selected for quality control.For inter-observer reliability assessment, the same data were collected and analyzed by two different operators.For intra-observer reliability assessment, the data were collected and analyzed twice by the same operator with an interval of half an hour.Linear regression correlation analysis was performed to analyze the relationship between CD and GA, BPD, FL, HC and AC.Intraclass correlation coefficient (ICC) and Bland-Altman analysis were used to analyze the repeatability of the analysis.Results In 518 (94.2％) of 550 fetuses, the CD was successfully measured.Positively correlations between the conus distance and the gestational age was observed.The CD was (10.0± 3.3) mm at ＞ 14-≤ 15 weeks (n=17), (27.7±3.8) mm at ＞ 20-≤ 21 weeks of gestation (n=18), (41.5±2.4) mm at ＞ 26-≤ 27 weeks (n=8), (54.7±3.0) mm at ＞ 32-≤ 33 weeks (n=17), and (71.9±2.7) mm at ＞ 41-≤ 42 weeks (n=6).Linear regression correlations between CD (mm) and FL, AC, HC, BPD and GA were:CD=1.04× FL (mm)-8.71, CD=0.23 × AC (mm)-10.11, CD=0.28× HC (mm)-18.10, CD=0.90× BPD (mm)-17.65, CD=2.34× GA (weeks)-20.94 (r=0.990, 0.985, 0.978, 0.974 and 0.973, respectively, all P ＜ 0.01).The measurement of the conus distance exhibited good reproducibility between different operators (ICC=0.984, 95％CI: 0.972-0.991) and for the same operator (ICC=0.992, 95％CI: 0.985-0.995) with the 95％ limits of agreement of-1.8 to 3.5 mm and-4.3 to 2.1 mm.Bland-Altman analysis showed that most of the measured values were within 95％ confidence interval suggesting good consistency.Conclusions The distance, between the end of the conus medullaris and the end of the last vertebral body under ultrasound scan, is positively correlated with FL and other ultrasonographic indicators, which implies that it could be used as a new index for position of fetal conus medullaris.

Objective To explore the joints and tendons characteristic features of high frequency ultrasound in asymptomatic hyperuricemia(AH) and to assess its value in AH diagnosis.Methods One hundred asymptomatic individuals with hyperuricemia (AH group) and 75 normouricemic subjects (control group) were examined by high frequency and color Doppler ultrasound.The joints,tendons and soft tissue of the knees,ankles and first metatarsal-phalangeal joints in two groups were examined.The correlations of serum urate(SU) level with double contour sign,bone erosion and articular cavity effusion were analysed.Results Hyperechoic deposition on the sulface of the articular hyaline cartilage (double contour sign) were found in the knees (35),ankles (17) and the first metatarsophalangeal joints (MTPJs,48) from the asymptomatic individuals with hyperuricemia,in contrast to none in the control group (P ＜0.05).Similar results were found in two groups of the bone erosion (30,25,20 vs 4,6,3,P ＜0.05),the effusion (28,36,41 vs 6,8,9,P ＜0.05) and the hyperechoic spots (19,18,22 vs 0,0,0,P ＜0.05).Patellar enthesopathy (4.5％ vs 0.6％,P ＜0.05) as well as achilles enthesopathy(8％ vs 0,P ＜0.05) and achilles tophi (6％ vs 0.6％,P ＜ 0.05) were more frequent in asymptomatic hyperuricemic than that of normouricemic individuals.No correlations between SU concentration and the presence of the double contour sign,the bone erosion and effusion were found (P ＞0.05).Conclusions There were some similar specific sonographic findings of gouty arthritis in the asymptomatic individuals with hyperuricemia.Also,these findings support high frequency ultrasound as a useful tool to detect anatomical damage in the joints,synovial tissue and tendons of asymptomatic individuals with hyperuricemia.

Radiofrequency thermocoagulation (RFT) of the gasserian ganglion is a routine and effective technique for the treatment of classical trigeminal neuralgia (CTN). In this study we compared its efficacy in patients with CTN and atypically symptomatic or mixed trigeminal neuralgia (MTN). Fifty-seven patients were treated with RFT for trigeminal neuralgia from June 2006 to February 2009. Thirty patients had CTN, and 27 had MTN. Outcomes were measured by using the visual analog pain scale (VAS) and patients' reports of quality of life (QOL), medication usage, and complications over a follow-up period of up to 3 years. Our results showed that the patients with MTN were younger, tended to have bilaterial involvement of the first division, and were unresponsive to treatment. All surgeries were completed smoothly. About 86.7% CTN patients and 48.1% MTN patients responded immediately to RFT. The VAS scores were significantly higher in the CTN group than in MTN group (P<0.05). Kaplan-Meier curves showed that 1-year, 2-year, and 3-year pain relief rates were 76.7%, 73.3%, and 73.3% in the CTN group and 46.6%, 41.4%, and 41.4% in the MTN group, respectively. The rates of pain relief for both groups leveled off at 2 years. Complications included numbness, dysesthesia, and anesthesia dolorosa. RFT did not cause any deaths and complications were low. The treatment was very effective for CTN and, to some degrees, effective for MTN. If numbness, dysesthesia, and anesthesia dolorosa are limited to the trigger area, QOL will be greatly improved.
