With the development of modern society,children get more and more attention from their parents.However,this situation often leads to parents' overprotection during their child-raising,especially when they have a child with pediatric diseases.Parents' inappropriate parenting may even affect the prognosis and outcome of their children's disease.According to recent studies about parenting of pediatric disease children,the parents would inevitably take overprotection,which might affect children's physical and mental health.Therefore,It is recommended that parents should correctly understand the diseases and their children,and choose appropriate parenting.

Objective:To evaluate the clinical feasibility and image quality of three-dimensional breath-hold gradient and spin-echo (3D BH-GRASE) sequence in magnetic resonance cholangiopancreatography (MRCP).Methods:In this prospective study, 59 patients with clinically suspected pancreaticobiliary duct disease performed MRCP with both 3D BH-GRASE and 3D respiration-triggered turbo spin-echo (3D RT-TSE) sequences on 3.0 T scanner in the Affiliated Zhangjiagang Hospital of Soochow University from November 2017 to December 2018. The overall image quality was scored independently by 3 experienced radiologists based on the visibility of different anatomical features of the pancreaticobiliary duct. For comparing the 2 sequences, the statistical difference in scan time was assessed with a paired t test; while subjective scores, signal-to-noise ratios (SNR), contrast ratios (CR) and contrast noise ratios (CNR) were compared with Wilcoxon signed rank test. Results:The scan time of 3D BH-GRASE sequence was 16.4 s while that of 3D RT-TSE was (258.6±42.2) s. Their difference was statistically significant ( t=44.073, P<0.001), with the scan time for 3D BH-GRASE shortened by 94%. The overall quality scores of 3D BH-GRASE images were better than those of 3D RT-TSE ( Z=-6.595, P<0.001). There was no statistical difference ( P>0.05) in the scores regarding the visibility of the upper, middle and lower parts of common bile duct and the first and second branches of left and right hepatic ducts. For visualizing the bottom, body, neck and duct of gallbladder, the 3D BH-GRASE sequence received a higher score than the 3D RT-TSE sequence ( P<0.001). For displaying the proximal, middle and distal segments of main pancreatic duct, the 3D RT-TSE sequence was scored higher than the 3D BH-GRASE sequence ( P<0.05). There was no significant difference of SNR between the two sequences ( Z=0.403, P=0.687), whereas CR and CNR of 3D RT-TSE MRCP were better than those of 3D BH-GRASE MRCP ( Z=6.215, P<0.001 and Z=3.046, P=0.002, respectively). Conclusion:Under the prerequisite of ensuring image quality, a proper use of 3D BH-GRASE sequence can significantly shorten the scan time and thus greatly improve the working efficiency of MRCP examination.

Objective To investigate the association between the phosphodiesterase 4D(PDE4D) gene rs153031 polymorphism and the susceptibility of unstable angina pectoris(UAP) in Chinese Han population of Changwu region .Methods The PDE4D gene rs153031 polymorphism was genotyped by Taqman probe in 172 UAP patients(UAP group) ,as well as in gender-and-age-matched 220 subjects without coronary heart disease(CHD)(control group) .Results In this crowd ,there was PDE4D gene rs153031 poly-morphism in patients with UAP and in subjects without CHD .Compared with control group ,frequencies of GG ,GA ,AA genotypes and G allele of rs153031 in UAP group showed no statistical differences (P> 0 .05) .Conclusion In Chinese Han population of Changwu region ,PDE4D gene rs153031 polymorphism shows no association with the susceptibility of UAP .

Lignin degradation products are toxic to microorganisms, which is one of the bottlenecks for fuel ethanol production. We studied the effects of phenolic ketones (4-hydroxyacetophenone, 4-hydroxy-3-methoxy-acetophenone and 4-hydroxy-3,5-dimethoxy-acetophenone) derived from lignin degradation on ethanol fermentation of xylose and cellular lipid composition of Pichia stipitis NLP31. Ethanol and the cellular fatty acid of yeast were analyzed by high performance liquid chromatography (HPLC) and gas chromatography/mass spectrometry (GC/MS). Results indicate that phenolic ketones negatively affected ethanol fermentation of yeast and the lower molecular weight phenolic ketone compound was more toxic. When the concentration of 4-hydroxyacetophenone was 1.5 g/L, at fermentation of 24 h, the xylose utilization ratio, ethanol yield and ethanol concentration decreased by 42.47%, 5.30% and 9.76 g/L, respectively, compared to the control. When phenolic ketones were in the medium, the ratio of unsaturated fatty acids to saturated fatty acids (UFA/SFA) of yeast cells was improved. When 1.5 g/L of three aforementioned phenolic ketones was added to the fermentation medium, the UFA/SFA ratio of yeast cells increased to 3.03, 3.06 and 3.61, respectively, compared to 2.58 of the control, which increased cell membrane fluidity and instability. Therefore, phenolic ketones can reduce the yeast growth, increase the UFA/SFA ratio of yeast and lower ethanol productivity. Effectively reduce or remove the content of lignin degradation products is the key to improve lignocellulose biorefinery.

Medically unexplained physical symptoms in patients are abbreviated to MUPS. At present, they are treated as psychological disorders. Beginning with the definition of MUPS and the influence to medical diagnosis and treatment, this article discusses on the countermeasure, patient management, medical practice and medical ed-ucation on the basis of etiology analysis and systematic assessment.

Objective To investigate the immediate effects of lower limb with open chain weight-adding on joint position sense and gait symmetry in stroke patients. Methods From January, 2016 to January, 2017, 39 stroke patients were included. Their joint position sense and gait symmetry were compared before and after weight-adding. The joint position senses of active reproduction of active positioning (ARAP) and passive reproduction of passive positioning (PRPP) were assessed during lower limb straight leg raise. The gait symmetry was also as-sessed and three indexes were recorded including the symmetry of foot rotation angle, step length and percentage of single leg support phase. Results After weight-adding, the position sense of PRPP did not improve (t=0.832, P=0.832), nor of the symmetry of foot rotation an-gle (t=-0.704, P=0.483) and percentage of single leg support phase (t=0.381, P=0.702);the position sense of ARAP improved (t=3.158, P=0.011), as well as the symmetry of step length (t=2.022, P=0.041). Conclusion The lower limb with open chain weight-adding could im-prove the active joint position sense and symmetry of step length.

Objective:To study the relation ship between the branch patterns of inferior mesenteric artery (IMA) and imaging pelvic measurement parameters for anastomotic leakage (AL) after anterior resection (AR) of rectal cancer.Methods:Five hundred thirty-four patient were enrolled from Jan 2008 to Dec 2018 at the General Surgery Department of Guizhou Provincial People's Hospital. The AL related imaging risk factors were analyzed by chi-square test or Fisher's exact test.Results:AL was found in 36 (6.7%) patients. AL related mortality rate was 11.1% (4/36) compared to 0.4% (2/498) in those without the complications of no AL cases ( P<0.001). Seven pelvic imaging measurement results were attained in 412 patients including anteroposterior diameter of the inlet of the pelvis, anteroposterior diameter of the outlet of the pelvis, upper edge of the symphysis pubis to the tip of the coccyx, sacrococcygeal distance angle from the lower edge of the pubis to the upper edge of the pubis to the sacral promontory, distance between the ischial spines and that of ischial tuberosity. Univariate analysis showed that there was no significant relationship between the above 7 pelvic measurement parameters and the occurrence of AL (all P>0.05). There was no significant relationship between branch patterns of IMA and AL after rectal cancer surgery ( P=0.712). Conclusion:AL as a severe postoperative complication in rectal cancer patients undergoing AR procedure were caused by multiple factors. Neither IMA branch patters nor pelvic imaging measurement seem to be related to the occurrence of AL after AR for rectal cancer.
