Objective To statistically summarize the adverse reactions of anti-TB drugs treatment,to analyze the influencing factors of leucopenia and to compare the effect of Qijiao Shengbai Capsule and Leucogen Tablet in the treatment of leucopenia.Methods The adverse reactions in 840 TB patients diagnosed from September 2014 to November 2015 were statistically analyzed.The influencing factors of leucopenia were analyzed.Finally,the effect of Qijiao Shengbai Capsule(n=480) and Leucogen Tablets (n=360) for treating leucopenia.Results Clinicians paid less attention to routine blood monitoring (39.4 ％).Among adverse reactions,the damage of liver function had the highest incidence rate(abnormal liver enzymes 27.0％,increased bile acid 8.2％),followed by leukopenia [25.4％,mainly degree Ⅰ (16.9％)];female patients(P=0.000) and complicating liver damage(P=0.010) might be the risk factors of leukopenia.After treatment by two kinds of drug,white blood cells count was increased,the difference was statistically significant(P=0.000).Conclusion The occurrence rate of leucopenia is higher,females and liver function damage are easier to appear,so more attention should be paid to monitoring the blood routine in return visit.The two kinds of drug for treating leucopenia induced by anti-TB drugs have definite effect and could be used in clinic.

Objective To investigate the effect and significance of AIS-ISS in assessing injury severity and prognosis of aged trauma patients.Methods A retrospective study was done on data of 2 599 patients hospitalized over 24 hours from October 2009 to September 2012.There were 597 patients aged 60 years or over (aged group) and 2 002 patients aged below 60 years (non-aged group).Injury causes,ISS,complication incidence,emergency operation rate,and ICU treatment were compared between the two groups.Results Similar in causes of injury,the two groups were mainly injured from traffic accidents and falls on the ground or from height.ISS was (10.7 ± 7.8) points in aged group and (10.4 ± 8.3) points in non-aged group,with no significant difference (t =0.653,P ＞ 0.05).Incidence of major complications was higher in aged group than in non-aged group (P ＜ 0.01).Top three complications were pulmonary infection or atelectasis (4.36％),shock (4.19％),and urinary infection (3.52％).Lower emergency operation rate (21.44％ vs 30.57％,P ＜ 0.01),higher ICU treatment (75.71％ vs 36.26％,P ＜ 0.05),and higher mortality (3.85 ％ vs 2.25％,P ＜ 0.05) were observed in aged group when compared to non-aged group.Conclusions AIS-ISS should be carefully selected to evaluate injury severity and prognosis of the aged trauma patients.Early total care should be performed for the aged trauma patients even if AIS-ISS is relatively low.

Objective To provide better emergency and patient services in well-equipped comprehensive hospitals, the organization and wisdom therapeutic strategy are of great importance for the recovery of injured patients from the earthquake zone. Method From 12 May 2008, following the 8.0 Magnitude earthquake in Wenchuan county of Sichuan Province, six Chongqing hospitals with third class in grade A were involved in the rescue of the injured patients with great effort. A total of 533 patients were retreated and followed up from quake zone. All the patients were scored with ISS and AIS system. The profiles of the patients examined, operated and clinical infection investigation were documented. Results Of 533 patients, the number of the patients whose ISS is below 16 is 456 (83.6%), the number between 16 and 25 is 65 (12.2%), and the humor above 25 is 12 (2.3%). The patients were classfled based on their fracture parts as follows: head and neck (n = 42), face (n = 7), chest (n = 114), abdominal and cavitas pelvis (n =81), limb and pelvis (n =314), body surface (n =205), with 180 single fracture site, 139 of them being two combined fracture sites, and 114 of them being above three combined fracture sites. Thirty-two of the patients were suffered from amputation. The number of patients suffered from crushing syndrome reached 21, with 281 surgical operations in hospitals. Seventy-nine patients were suffered from infections including 87.3% of pre-hespital infections. The results from bacteria culture and antibiotic susceptibility showed that the infected bacteria mainly involved in Escherichia coli, Staphylococcus anreus, Staphylococcus haemolyticns, Klebsiella pneumoniae, Baumanii, Aerobacter cloacae, Pseudomonas aeruginosa, C type chain coccus, Bacillus aerogenes capsulatus. The antibiotic susceptibility to diverse bacteria has no obvious changes and exists partial overlapping, and infected patients should be given the treatment of cephalosporin, macrolide antibiotic and so on. Conclusions For the emergency conditions after the catastrophe, the comprehensive hospitals must be prepared to meet large quantities of severe trauma and infection therapy. The scientific selection of antibiotics in the combinative therapy is of great importance to the enhancement of early specific treatment, prevention of severe trauma complications and rehabilitation of patients.

OBJECTIVETo analyze two fetuses with multiple malformations revealed by ultrasonography using single nucleotide polymorphism array (SNP array), and to explore the strategy for the prenatal diagnosis of 1p36 deletion syndrome.

METHODSAmniocentesis was performed on the two pregnant women. Amnion fluid cells were cultured, and karyotypes of the fetuses were determined through G-banding analysis. Whole genome SNP array was used to detect genomic anomalies of the two fetuses. The karyotypes of their parents were determined through G-banding analysis of peripheral venous blood samples.

RESULTSG-banding analysis showed a 46,XY,add(1p36)? and a 46,XX,add(1p36)? karyotype for fetuses 1 and 2, respectively. SNP array analysis showed that the fetus 1 had arr[19]1p36.33p36.32 (752 566 - 3 393 462)×1 and 7q35q36.3 (144 480 549 - 159 119 486)×3, and fetus 2 had arr[19]1p36.33p36.23 (752 566 - 8 362 754)×1, 6p25.3p22.3 (204 909 - 20 182 185)×3. The mother of fetus 1 had a 46,XX,t(1;7)(p36;q35) karyotype, and the mother of fetus 2 had a 46,XX,t(1;6)(p36;p22) karyotype. The karyotypes of both fathers appeared to be normal.

CONCLUSIONSNP array has the advantages such as high sensitivity and high accuracy for prenatal diagnosis, and can provide more detailed information for genetic counseling of 1p36 deletion syndrome.

OBJECTIVETo explore the value of multiplex ligation-dependent probe amplification (MLPA) for rapid detection of aneuploidies and structural chromosomal abnormalities during prenatal diagnosis.

METHODSTwo hundred and eight six amniotic fluid samples were analyzed with both MLPA and conventional karyotyping. Structural abnormalities were verified with array comparative genomic hybridization.

RESULTSTen cases of trisomy 21, 2 cases of trisomy 18, 1 case of trisomy 13, 1 case of mosaic trisomy 21, 1 case of 45,X, 1 case of large deletion of Xp, 1 case of trisomy 18p and 1 case of large deletion of 18p and 18q were identified. The same results were derived by both MLPA and conventional karyotyping. Structural abnormalities were verified by array comparative genomic hybridization (aCGH) with 100% accuracy.

CONCLUSIONIn addition to aneuploidies, MLPA can rapidly identify large deletions and duplications of chromosomes 21, 18, 13, X and Y. MLPA is supplementary to conventional karyotyping for identification of such chromosomal abnormalities prenatal diagnosis.

Objective:To investigate the relationship between polymorphisms and haplotypes of cyclin-dependent kinase inhibitor 2B antisense RNA 1 ( CDKN2 B- AS1) gene and the risk of ulcerative colitis (UC). Methods:From January 2012 to January 2021, a total of 534 UC patients diagnosed at the Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University (Yuying Children′s Hospital) and during the same period 560 gender- and age-matched healthy controls were selected. Genotypes of CDKN2 B- AS1 (rs1063192, rs10757274, rs10757278, rs1333048, rs2383207) in venous blood were determined by matrix assisted laser desorption ionization time-of-flight mass spectrometry technique. Unconditional logistic regression was used to analyze the difference in the distribution of CDKN2 B- AS1 gene polymorphisms between UC patients and healthy controls, as well as the influence on the clinicopathologic characteristics of UC patients. Software Haploview 4.2 was used to analyze the linkage disequilibrium and haplotype. Chi-square test was used for statistical analysis. Results:The frequencies of variant genotype (AG+ GG) and variant allele (G) of rs1063192 in UC patients were higher than those in healthy controls (32.4%, 173/534 vs. 24.8%, 139/560; 18.1%, 193/1 068 vs. 13.7%, 153/1 120), and the differences were statistically significant ( OR=1.45 and 1.40, 95% confidence interval(95% CI) 1.12 to 1.89 and 1.11 to 1.77, P=0.006 and 0.004, corrected P=0.030 and 0.020). The frequency of variant allele (G) of rs10757274 in UC patients was lower than that in healthy controls (34.7%, 371/1 068 vs. 39.5%, 442/1 120), and the difference was statistically significant ( OR=0.82, 95% CI 0.69 to 0.98, P=0.025). However, the difference was not significant after Bonferroni correction (corrected P>0.05). According to the Montreal classification, the frequency of homozygous variant genotype (GG) of rs1063192 in the patients with extensive colitis was higher than that in patients with proctitis plus left-sided colitis (6.6%, 14/211 vs. 1.9%, 6/323), and the difference was statistically significant ( OR=3.92, 95% CI 1.47 to 10.42, P=0.006, corrected P=0.030). There was linkage disequilibrium among rs10757274, rs2383207, rs10757278 and rs1333048 of CDKN2 B- AS1 gene. The frequency of haplotype GGGC in UC patients was lower than that in healthy controls (33.3%, 355.5/1 068 vs. 37.8%, 423.4/1 120), and the frequency of haplotype AGGC in UC patients was higher than that in healthy controls (6.7%, 71.7/1 068 vs. 3.6%, 40.3/1 120), and the differences were statistically significant ( χ2=4.81 and 11.16, P=0.028 and<0.001). Conclusions:The variation of rs1063192 in CDKN2 B- AS1 gene may increase the risk of UC. The risk of extensive colitis in patients carrying homozygous variant genotype (GG) of rs1063192 may rise. Among the haplotypes composed of rs10757274, rs2383207, rs10757278 and rs1333048, the risk of UC may decrease in the individuals carrying haplotype GGGC. However, the risk of UC may increase in the individuals carrying haplotype AGGC. The correlation between the variation of 10757274 and the risk of UC still needs to be further verified by expanding the sample size.

Objective:To retrospectively analyze the effects of vitamin D3 supplementation on clinical remission of patients with Crohn′s disease (CD) in the treatment of infliximab (IFX).Methods:From January 2014 to January 2020, 73 patients with initial moderate to severe CD (50 patients with vitamin D deficiency (the level of serum 25-hydroxyvitamin D (25(OH)D)<50 nmol/L)) receiving IFX treatment at Department of Gastroenterology were screened from the clinical database of the Second Affiliated Hospital of Wenzhou Medical University. Harvey-Bradshaw index (HBI) was applied to evaluate the disease activity of CD patients. All the patients underwent IFX treatment (5 mg/kg) for at least 54 weeks. According to whether vitamin D3 (125 U/d) was supplemented during IFX treatment, the patients were divided into supplemented group ( n=37) and non-supplemented group ( n=36). In supplemented group, the level of 25(OH) D of patients at the 54th week was compared with that before IFX treatment. At the 54th week, the clinical remission rate and decline range of HBI were compared between supplemented group and non-supplemented group. And the influencing factors of clinical remission rate were analyzed in CD patients. Paired t test, independent sample t test, chi-square test and multivariable logistic regression were used for statistical analysis. Results:In supplemented group, the level of serum 25(OH)D at the 54th week was higher than that before IFX treatment ((50.83±15.45) nmol/L vs. (37.68±16.75) nmol/L), and the difference was statistically significant ( t=-4.55, P<0.001). At the 54th week, the clinical remission rate of supplemented group was higher than that of non-supplemented group (83.8%, 31/37 vs. 61.1%, 22/36), the decline range of HBI was larger than that of non-supplemented group (7.41±3.00 vs. 6.28±2.75), and the differences were statistically significant ( χ2=4.71, t=2.41; P=0.030 and 0.023). The results of multivariable logistic regression analysis showed that vitamin D3 supplementation was an independent factor affecting the clinical remission rate in CD patients ( n=73) and the patients with vitamin D deficiency ( n=50) ( b= -1.67 and -1.92 , P=0.015 and 0.019). Conclusions:Vitamin D3 supplementation can significantly improve the clinical remission rate in CD patients with IFX treatment, especially in CD patients with vitamin D deficiency.
