Objective:To analyze the mutation sites and characteristics of phospholipase CE1( PLCE1) gene in children with primary nephrotic syndrome(PNS) in Zhuang, Guangxi, China, so as to explore the expression status of PLCE1 protein in peripheral blood of PNS patients. Methods:(1)Blood samples of 154 Zhuang children with PNS and 98 healthy children of Zhuang nationality from July 2015 to September 2017 in Affiliated Hospital of Youjiang Medical College for Nationalities were collected to sequence PLCE1 gene with FastTarget target gene capture method in the combination with next generation sequencing.Based on the comparison between mutation results and information from the database, the pathogenicity, phenotype and distribution characteristics of these mutation sites were discovered and appraised.(2)The concentration of PLCE1 protein in serum samples were measured by enzyme-linked immuno sorbent assay, then the data of PNS group and healthy control group were compared and analyzed statistically with SPSS 25.0. Results:(1)A total of 18 low-frequency mutations of PLCE1 were observed, 5 of them(c.670C>T, c.578T>C, c.923G>T, c.4916C>T, and c. 5927_5929del) were found only in the PNS group, and 3 of them occurred in both PNS group and healthy control group: c.176C>T, c.389T>C, and c. 4304C>T.Five newly discovered mutations (c.923G>T, c.958T>A, c.1151C>T, c.2341A>G, and c. 3592G>C)were discovered and only c. 923 G>T is pathogenic mutation of PLCE1.(2)The concentration of PLCE1 protein in healthy control group was 414.65 (231.20, 729.81) ng/L and the level of PLCE1 in PNS group was 237.84 (116.14, 535.85) ng/L, ( Z=-3.212, P<0.001), and the value of PNS group was lower than that in the healthy control group. Conclusions:(1)As a new pathogenic mutation of PLCE1, c.923G>T was found.(2)The phenotype of PLCE1 gene mutation in Zhuang children with PNS was diverse, and they may differ by race and region.(3) PLCE1 protein of serum may act as a protective protein to guarantee various life activities of cells by participating in multiple signal transduction pathways.

OBJECTIVE:
To study the expression of BIRC6 in renal cancer tissues and investigate the effect of BIRC6 silencing on apoptosis and autophagy of 786-O cells.
METHODS:
Twenty surgical specimens of renal cancer tissues and adjacent renal tissues were collected from Meizhou People's Hospital between February, 2016 and December, 2018 for detection of BIRC6 protein expression using immunohistochemistry. Renal cancer 786-O cells were transfected with a control small interfering RNA (siRNA) or BIRC6 siRNA
RESULTS:
The expression of BIRC6 protein was significantly higher in renal cancer tissues than in the adjacent renal tissues. Western blotting showed that siRNA-mediated silencing of BIRC6 significantly lowered the expression of BIRC6 in 786-O cells. In the cells with BIRC6 silencing, treatment with 12.5, 25, 50, 100 and 200 μg/mL 5-FU resulted in significantly higher proliferation inhibition rates than in the cells transfected with the control siRNA (
CONCLUSIONS
Interference of BIRC6 mediated by siRNA can inhibit autophagy and promote 5-FU-induced apoptosis to enhance the sensitivity of 786-O cells to 5-FU.

Objective To evaluate the efficacy of quadrates lumborum block for unilateral inguinal hernia repair in elderly patients. Methods Fifty-eight elderly patients with unilateral inguinal hernia of both sexes, aged 65-80 yr, with body mass index of 18-25 kg∕m2 , of American Society of Anesthesiolo-gists physical status Ⅱ or Ⅲ, scheduled for elective unilateral tension-free repair, were divided into 2 groups ( n=29 each) using a random number table method: iliohypogastric-ilioinguinal nerve block group (group T) and quadrates lumborum block group (group Q). Iliohypogastric-ilioinguinal nerve block with arteria circumflexa ilium profunda as a marker was carried out with 0. 33% ropivacaine 20 ml under ultra-sound guidance in group T. The anterior approach to quadratus lumborum block was performed with 0. 33%ropivacaine 20 ml under ultrasound guidance in group Q. Operation was started after the height of sensory block was assessed by pin-prick test at 30 min after block. When the blocking effect did not meet the opera-tion requirements, an increment of 1% lidocaine 2. 5 ml was given every time in the surgical field until op-eration requirements were met. Dexmedetomidine was intravenously infused at a rate of 0. 03-0. 07μg·kg-1 ·min-1 during surgery until the end of surgery to maintain Narcotrend index between 80 and 90. When postoperative visual analogue scale score >3, parecoxib sodium 40 mg was intravenously injected, and if marked pain relief was not found 10 min later, tramadol hydrochloride 50-100 mg was intravenously injected. The upper spread of sensory block and intraoperative requirement for additional local anesthetics were recorded at 30 min after nerve block. The requirement for parecoxib and tramadol was recorded within 48 h after operation. The development of inadvertent intravascular injection of local anesthetics, local anes-thetic intoxication and postoperative nausea and vomiting, nerve block of lower extremity and uroschesis was recorded. Results Skin pain disappeared at the plane of T11-L1 in group T and at the plane of T9-L1 in group Q. Compared with group T, the intraoperative requirement for and consumption of local anesthetics, postoperative requirement for parecoxib and tramadol, and postoperative incidence of nausea and vomiting were significantly decreased in group Q ( P<0. 05) . Conclusion Quadrates lumborum block provides bet-ter efficacy for unilateral inguinal hernia repair than iliohypogastric-ilioinguinal nerve block in elderly pa-tients.

Objective To investigate the semantic priming of boy with attention deficit hyperactivity disorder( ADHD) and explore whether the semantic priming deficits was associated with behavioral problems by event-related potential(ERP). Methods Thirty boy with and without ADHD aged from 7 to 13 years were asked to finish the semantic Semantic judgment task. The study took advantage of t-test ( independent-samples) to compare the amplitude and latency of the N400 in both groups,as well as behavioral data.Behav-ioral problems were assessed by the Achenbach child behavior checklist( CBCL) ,and Pearson correlation a-nalysis were used to explore the relationship between behavioral problems and semantic priming. Result-s Under the condition of semantic correlation,the hyperactive factor of CBCL in ADHA group was positively correlated with ERP N400 amplitude ( r=0.44,P<0.05) and negatively correlated with reaction accuracy ( r=-0.48,P<0.05).Under the semantic irrelevant condition,the latency of ERP N400 in ADHA group was pos-itively correlated with hyperactivity factor (r=0.53,P<0.05)and aggression factor of CBCL(r=0.62,P<0.05).The N400 amplitude of the ADHD group was significant higher than that in the control group under se-mantic related conditions((-11.36±4.77)μV vs (-7.66±5.24)μV,P=0.006),and the latency of the N400 in ADHD was more delay((369.6±44.09)ms vs (341.27±24.54)ms,P=0.004),and the reaction times (RT) was much longer((936.18±135.03)ms vs (857.78±103.45)ms,P=0.014).The latency of the N400 in ADHD was more delay than that in the control group under semantic irrelevant conditions ( ( 383. 93 ±29.66)ms vs (362.33±29.66)ms,P=0.012),and accuracies of ADHD group was lower than that of control group(0.43±0.39 vs 0.81±0.23,P<0.01).Conclusion The present result indicates that children with ADHD exhibit a deficit in the semantic priming mechanism,and the deficit is positively correlated with hy-peractivity and impulsiveness.

Objective To compare the differences of the development of mathematical cognitive characteristics between ADHD children and normal children aged from 7 to 12 years old with event?related potentials ( ERP ) in the mathematical tasks, and to explore the neural mechanisms and characteristics. Methods ERP and behavioral data of 72 ADHD children and 88 normal children in three groups( 7?8 years old,9?10 years old,11?12 years old) were recorded,and analyzed N1,P2 and N2 components'amplitude and latency of Fz by judging the answers to simple calculation within 20. Results ( 1) Vertical comparative a?nalysis( the three age groups were compared):the differences of N1,P2 and N2 amplitudes in normal groups were considered to be statistically significant (right answer:N1(-3.8±2.1)μV,(-4.3±3.4)μV,(-2.2± 2.4)μV;P2(10.6±4.3)μV,(12.6±5.1)μV,(8.5±2.4)μV;N2(-6.5±3.1)μV,(-10.2±4.2)μV,(-6.8± 3.4)μV;error answer:N1(-2.8±2.7)μV,(-4.5±3.0)μV,(-2.9±2.5)μV;P2(9.3±5.9)μV,(12.1±5.0)μV,(8.2±3.6)μV;N2(-7.4±3.7)μV,(-11.4±5.5)μV,(-7.7±3.7)μV;all P<0.05),while was not sig?nificant in ADHD group(all P>0.05). (2)Horizontal comparative analysis(ADHD group and normal group were compared):N1 amplitude of ADHD group aged from 7 to 8 years old was higher than normal group’ s while judging the right answer((-5.3±2.4)μV,(-3.8±2.1)μV, P<0.05).P2 and N2 components’ ampli?tude of ADHD group aged from 9 to 10 years old were lower than of that normal group.(right answer:P2(9.6 ±4.4)μV,(12.6±5.1)μV;N2(-8.0±4.3)μV,(-10.2±4.2)μV;error answer:P2(9.6±4.4)μV,(12.1± 5.0)μV;N2(-7.9±4.6)μV,(-11.4±5.5)μV;all P<0.05).(3)Comparison of different tasks(the judge?ment of right and wrong answer):There was no statistically significant difference between ADHD and normal group in amplitude( P>0.05) . The latent period of the wrong answers was longer than that of the right ones among normal groups aged from 11?12 while the difference of ADHD group had no statistical significance ((312.9±42.3)ms,(292.2±21.2)ms, P<0.05). Conclusion The development trend of mathematical ERP component in ADHD children is different from normal ones,and it is closely related to the maldevelopment of frontal lobe.The characteristics of cognitive deficit differ from ages.ADHD children in low and intermediate level were damaged primarily with inhibition function,while the senior were damaged mainly in collision de?tection function.

Objective To explore the developmental characteristics of semantic processing of chil-dren with attention deficit hyperactivity disorder( ADHD) by comparing the event related potential in normal children and ADHD children ( ages 7-11 years old) .Methods 83 ADHD children and 93 normal children ranging from 7 to 11-year were divided into 5 groups to analyze the difference of the amplitude and latency of ERP N400 in three conditions:the related,unrelated and pesudoword after the Chinese character word visual stimulus task.Results (1) The related condition:the amplitude of the 7 years old normal children group was higher than 11 years old((-10.67±4.39)μV,(-4.62±3.55)μV;P=0.005);and the amplitude was highest in 8 years old group in children with ADHD( (-10.77±6.66) ms, F=2.54, P=0.046) .The latency in normal children was shorter at 8 years old((311.7±33.1) ms, P<0.05),but was shorter at 9 years old in ADHD group.( 2) The unrelated condition:the amplitude of normal children aged 10 years was higher than that of other age groups.( 3) The pesudoword condition:the amplitude of 9 years old normal children was higher than other age groups.The amplitude of ADHD in children aged 9 years was higher than that in other age groups( (-16.08±7.14)μV, P<0.05) .Conclusion In the semantic related conditions,the amplitude of the N400 in ADHD children at the age of 8 and the latency at the age of 9 are significantly developed,and in the false words conditions,it is at the age of 11.This suggests that the ability of 7-11 years old ADHD chil-dren's orthographic semantic processing and cognitive development are slower than normal.N400 can better reflect the children's early language cognitive ability,and it is valuable for the early diagnosis of children with ADHD.
