Objective To analyze the serological detection results of hemolytic disease of newborns(HDN)in neonatal hyperbil-irubinemia and to explore the relationship between serological results and related factors.Methods The neonatal hemolytic three i-tems test were performed on blood specimens of 796 cases of neonatal hyperbilirubinemia.The relationship between the positive rate of HDN with the related factors such as blood type,specimens collecting time,hemoglobin level and serum total bilirubin value was analyzed.Results Among 796 cases of hyperbilirubinemia,184 cases were HDN(23.12%),in which 796 cases were ABO-HDN and 8 cases were Rh-HDN.The direct free antibody test,antibody release test and direct antiglobulin test were positive in 180 cases (22.61%),184 cases(23.12%)and 140 cases(17.59%)respectively.The HDN positive rate of the newborns with B blood type was higher than that of the newborns with A blood type,the difference between them had statistical significance(χ2 = 10.304,P <0.05).The HDN positive rate was closely related with the specimen collection time,moreover,the greater the day age,the higher the HDN positive rate,the difference showing statistical significance(P <0.05).The hemoglobin level and serum total bilirubin val-ue had statistically significant difference between newborns with HDN and those without HDN(P <0.05).Conclusion The posi-tive rate of HDN is high in newborns with hyperbilirubinemia.The hemolytic three items test should be performed as early as possi-ble.Combining with the hemoglobin level and serum total bilirubin value can increase the HDN detection rate.

Objective To explore the application of cancer pain standardized treatment in patients with lung cancer pain and clinical results.Methods 120 cases of lung cancer pain patients as the research object in Our hospital from April 2015 to June 2016,The patients were randomly divided into study group and control group,60 cases in each group,the patients in the control group were treated with routine therapy and nursing,and the patients in the study group were treated with normalized treatment and care of cancer pain,and then compared the two groups after treatment Pain status changes and adverse events and patient satisfaction statistics.Results There was no significant difference in pain status and VAS score between the two groups before treatment,but the pain status was relieved after treatment.The pain status of patients in the study group after standardized treatment of cancer pain changed significantly,the VAS score was lower than the control,the difference between the two groups was statistically significant(P<0.05).After treatment,the adverse events of the study group including non-on-time medication,syncope pressure sores and the incidence of self-mutilation or suicide were statistically significant And the difference was statistically significant(P<0.05).The satisfaction of the patients in the two groups showed that the satisfaction of the patients in the study group was significantly higher than that of the control group,The difference between groups was statistically significant(P<0.05).Conclusion The standardized treatment of cancer pain is effective in the treatment of patients with lung cancer pain.It can effectively relieve the pain and improve the quality of life and satisfaction of patients with lung cancer pain.It has broad clinical application and popularization value.

Objective To evaluate the treatment effects of middle and proximal phalangeal fractures with lateral fixation of mini-titanium plate.Methods From December 2011 to April 2015,56 patients (64 phalanges) suffered from closed middle and proximal phalangeal fractures were treated with lateral fixation of mini-titanium plate.There were 48 males and 8 females,aged from 17 to 65 years (average,36.3 years).Fractures included 25 cases of middle phalangeal fracture and 39 cases of proximal phalangeal fracture.According to site of fracture,12 cases were middle phalangeal condyle fractur,7 cases were middle phalangeal shaft fracture,6 cases were middle phalangeal base fracture,10 cases were proximal phalangeal condyle fracture,22 cases were proximal phalangeaal shaft fracture and 7 cases were proximal phalangeal base fracture.According to the type of fracture,13 cases were transverse,9 cases were short oblique,11 cases were long oblique,6 cases were spiral and 25 cases were comminuted fracture.All phalangeal fractures were exposed by lateral approach,in which the lateral band and oblique fibers of proximal phalanx were excised to fully expose proximal phalangeal fracture.After the reduction,the fractures were fixed with mini-titanium plate laterally.The Disabilities of the Arm,Shoulder and Hand (DASH)and the bilateral fingers total active motion (TAM) were employed to evaluate the functions.All patients took X ray during follow-up.Results All 56 patients were followed up from 9 to 47 months,average (14 ± 6) months.Phalangeal fractures were healed from 7 to 14 weeks,average (8.8 ± 2.4) weeks without loss of fixation or malunion.At final follow-up,DASH score were from 1.7 to 7.5,with an average of 4.8 ± 2.2.TAM of the fingers was excellent (＞ 90％ TAM of the contralateral side) in 33/64 (51.5％) cases,good (75％-90％ TAM of the contralateral side) in 30/64 (46.9％) cas es,fair (50％-75％ TAM of the contralateral side) 1/64 (1.6％) cases.Conclusion Lateral approach fully exposes middle and proximal phalangeal fractures and less interferes with the extensor mechanism.Lateral fixation with mini-titanium plate could provide stability and allow early motion.This technique may be an optional choice in clinical practice.

4,6-α-glucosyltransferases (4,6-α-GTs), which converts amylose into α(1-6) bonds-containing α-glucan, possesses great application potential in enzymatic synthesis of dietary fiber. Primers were designed according to the conserved motifs existing in the amino acid sequence of 4,6-α-GTs, and used to amplify a putative GTFB-Like 4,6-α-GTs gene (named as gtf16) from the genomic DNA of Lactobacillus. The gtf16 gene was cloned into the plasmid pET15b, expressed in Escherichia coli BL21(DE3), followed by purification and characterization. The optimum pH and the optimum temperature of the purified enzyme were 5.0 and 40 °C, respectively. The biotransformation product of this enzyme was systematically characterized by thin-layer chromatography, NMR spectroscopy, and hydrolysis reaction. The Gtf16-catalyzed product shows a similar structure to that of the isomalto/malto-polysaccharide (IMMP), which is the amylose-derived product catalyzed by GtfB from Lactobacillus reuteri 121. Moreover, The Gtf16-catalyzed product contains up to 75% of α(1-6) bonds and has an average molecular weight of 23 793 Da. Furthermore, the content of the anti-digestive components was 88.22% upon hydrolysis with digestive enzymes.

Objective To investigate the growth, development and health management of children with type 1 diabetes, and to provide guidance for the treatment of children with type 1 diabetes. Methods From June 2018 to June 2021, 86 children with type 1 diabetes diagnosed and treated in the Department of Endocrinology of our hospital from January 2000 to December 2002 were selected, including 41 males and 45 females, the onset age of 6-9 years old, all of whom were followed up by telephone. Height, weight, age of onset of youth, age of menarche, blood glucose control and complications were recorded and analyzed from onset to adulthood. Results The initial height of children were lower than those of children of the same age (P<0.05), and there was no difference in height between children of the same age and children of the same age when they reached lifetime height (P>0.05).The median age of initiation of puberty in boys was (12.10±1.50) years later than that in the general population (P<0.05), and the median age of initiation of puberty and menarche in girls were (11.20±1.40) years and (14.90±2.10) years later than that in the general population (P<0.05). 11.63% (10/86) of children HbAl-c <7.0%, 30.23% (26/86) in children with HbAl-c is 7.00% -8.00%, 58.14% (50/86) in children with HbAl-c > 8.0%. There were 1 (1.16%) cases of retinopathy and 4 (4.65%) cases of microalbuminuria. 84 cases (97.67%) were monitored for blood glucose or urine glucose, and only 2 cases were not monitored. Conclusion Due to poor self-control and growth, the blood glucose control of children with type 1 diabetes is often not ideal. Although complications are rare, most blood glucose control is not ideal and blood glucose detection is not enough. Therefore, It is necessary to strengthen the publicity and education of diabetes and regularly monitor blood glucose.
