Objective To study the effect of oxygen therapy combined with recombinant epidermal growth factor on cervical cancer radioactive dermatitis. Methods From October 2013 to October 2015 in Guangxi tumor hospital, 70 stage IIIB cervical cancer patients with radioactive dermatitis from intensity modulated radiation therapy (IMRT) were enrolled in the study, 35 cases with dermatitis occurring on odd date as the study group and another 35 with dermatitis occurring on even date as the control group. The former were treated with oxygen therapy combined with epidermal growth factor and the latter with recombinant epidermal growth factor alone. The two groups were compared in terms of curative effect, wound healing time and pain. Results The total effective rate of the research group was significantly higher than that of the control group (P<0.01). The healing time of the research group was significantly shorter than that of the control group (P < 0.001). Conclusion The oxygen therapy combined with recombinant epidermal growth factor is more effective in improving the cure rate, shorten healing time of dermatitis, reduce the pains from radiotherapy and help them through the radiotherapy process.

[Objective] To observe the effect of biological fertilizers on the yield and quality of Amomum villosum (AV). [Methods] Field experiment method was used to observe the effect of different kinds and different amount of biological fertilizers on AV. Biological fertilizers were: A (mainly composed of fermented chicken manure), B (mainly composed of fermented filter of sugarcane) and C (mixed with fertilizer A and biological fertilizer at certain proportion). The fertilizer amount was 150, 112 and 75 g****m-2 per time. Content of bornyl acetate in AV was detected by gas chromatography. [Results] The three kinds of biological fertilizers increased the yield of AV but had no obvious effect on its quality; high- and moderate-amount fertilizer increased the yield of AV, in particular fertilizer A (112 g?m-2 per time). The three kinds of fertilizers had no effect on the content of bornyl acetate in AV. [Conclusion] Reasonable application of fertilizers is one of the important ways to raise the yield of AV.

Objective To investigate rational management for pregnant women with intermediate risk of Down syndrome (DS) through a retrospective analysis of second trimester maternal screening results for DS.Methods Second-trimester triple maternal serum screening for DS was performed.High risk ( ≥ 1/270) pregnant women received prenatal diagnosis.Intermediate (1/1000 to 1/270) and low (＜1/1000) risk pregnant women received routine obstetric examination.Data of ultrasound diagnosis,karyotype analysis of amniotic fluid and postpartum follow-up were collected.Outcomes of pregnant women were retrospectively analyzed.The incidences of DS among three groups were compared.Data of different groups were compared with Fisher exact or Chi-square test.Results Eighty-six thousand eight hundred and seventy-four pregnant women accepted maternal serum screening and outcomes of 86 126 cases were followed up,among which 4342 cases were DS high risk,8196 intermediate and 73 588 low risk.The incidence of DS was 6.22‰(27/4342) for high risk,0.73 ‰ (6/8196) for intermediate risk and 0.04 ‰ (3/73 588) for low risk group.The incidence of DS was higher in high risk group than in intermediate risk group (Fisher exact probability,P=0.000),and was higher in intermediate risk group than in low risk group (Fisher exact probability,P=0.000).Comparison among the three subgroups within intermediate risk group showed no significant differences (x2 =0.047,P =0.977).Conclusions Pregnant women with intermediate risk of DS should be paid more attention.Reasonable management such as ultrasound diagnosis and prenatal consultation should be provided.

Objective To analysis and summary the chromosome abnormal existing in old pregnant women from 2002 to 2013,and to provide basis for clinicians intervene the fetus with chromosome disorders.Methods The 4 539 pregnant women in Ningbo city from 2002 August to 2013 October accepted the fetal karyo type detection,were retrospective analyzed,the frequency of abnormal chromosomal karyotypes was calculated according to different age groups,and the pregnancy outcomes of the old pregnant women were followed up.Thechi-square testswere performed on the frequency dateof the abnormal chromosome karyotype,polymorphism,and serum screening of high risk for fetal chromosome detection of less than 35-years-old pregnant women.Results The total of advanced maternal age pregnancyduring the past 11 years in Ningbo City is 32 080,and the follow-up rate was 99.90％,there are 10 infants borned with chromosomal abnormalities,the 1 290 caseswere detected withadverse pregnancy.A total of 4 539 advanced maternal age pregnancyaccepted amniocentesis,in those we found 107 cases of chromosome abnormality fetus,116 cases of polymorphism.A total of 5 232 high-risk pregnant women accepted the serum screening in the same period (less than 35 years old),finding 135 cases of fetal chromosome abnormal and 69 cases of polymorphism.Conclusion To strengthen the prenatal diagnosis,especially for puerperae above the age of 39,will lower the birth rate of infants with chromosome disease and will be conducive to the high quality of population in Ningbo.

Objective To investigate the effects of growth-discordant twin pregnancies on neonatal thyroid stimulating hormone (TSH) level and congenital hypothyroidism (CH).Methods A total of 3 444 live-birth twin neonates born between January 1,2012 and December 30,2014 in Ningbo City were enrolled.Blood samples via heel puncture were collected and tested.Incidence of CH in singleton and twin neonates was compared.Deviation of birth weight larger than 25％ in twin neonates was set as the criteria for discordant growth.TSH and 17 α-hydroxylase levels in CH twins and normal twins,with or without discordant growth,were compared.Chi-square and non-parametric statistics were performed for data analysis.Results The incidence of CH in twin neonates was 0.56％ (19/3 444),higher than that in singleton neonates [0.09％ (203/225 712),x2=76.225,P＜0.01].Among nineteen CH twins,CH occurred in both twins in eight cases (four twins) and in one of the twins in eleven cases.The gestational age at birth in the eight CH twins were less than 37 weeks,with four males and four females;five were low birth weight infants;one twin were dichorionic,and three twins were monochorionic.In the eleven cases of CH occurring in one of the twins,the gestational age was less than 37 weeks in nine cases,eight were low birth weight infants,six were male and five female;seven were monochorionic and four were dichoronic twins.Five cases of temporary hypothyroidism were all low birth weight infants among the growth-discordant twins.CH cases in growth-discordant group had lower birth weight than their normal twins [M(P25-P75),2 100 (1 800-2 600) vs 2 770 (2 530-2 960) g,Z=4.369],and a higher TSH level [15.4 (11.8-18.5) vs 6.4 (4.8-7.9) mU/L,Z=6.339] (both P＜0.05).In normal twins with or without discordant growth,the neonates with a lower birth weight had a higher TSH level [3.6(2.5-4.7) vs 2.4(1.8-2.9) mU/L,Z=0.962] in weight consistent group,compared with 6.0(4.4-7.8) vs 3.4(1.9-4.1) mU/L in weight inconsistent group (Z=4.369),both P＜0.05.Conclusions In the growth-discordant twins,neonates with a lower birth weight have a higher TSH level and a higher risk of temporary hypothyroidism.

OBJECTIVE: To explore the clinical features and genomic abnorm ality of a fetus enlarged multicystic dysplastic kidneys with oligohydramnios caused by NPHP3 gene mutation. METHODS: The fetuse was found to have multicystic dysplastic kidneys with oligohydramnios upon ultrasonography during the second trimester. Following induced abortion, fetal tissue was collected for the extraction of DNA, chromosomal microarray analysis (CMA) and whole exome sequencing (WES). Sanger sequencing was used to verify the suspected variants in the family. RESULTS: Antenatal ultrasound examination at 19 weeks showed "polycystic" kidneys with Oligohydramnios. Delivery was by induced labour because of the critically low amniotic fluid volume. Testing of CMA was normal. WES showed a compound heterozygous mutation of c.1817G>A, p.W606X; c.432dupA, p.E145Rfs*18 mutations are novel mutations in this study. CONCLUSION The research may further expand the NPHP3 gene mutation spectrum. Enlarged multicystic dysplastic kidneys with oligohydramnios caused by NPHP3 gene mutation at least include one or two splice site mutation, frameshift mutation or nonsense mutation foetal poor prognosis.

OBJECTIVE: To establish a newborn screening system for Duchenne muscular dystrophy (DMD) through assessment of MM isoenzyme of creatine kinase (CK-MM) activity. METHODS: The CK-MM level was detected using dry blood spot filter paper from 10 252 male newborns. The results were grouped based on their gestational age, sampling time and intervals between the experiments. The threshold value for CK-MM necessitating genetic testing was determined. Next-generation sequencing (NGS) was carried out for those with a CK-MM value over the threshold, and the result was verified by multiplex ligation-dependent probe amplification (MLPA). RESULTS: Based on the result of non-parametric rank sum test, the median CK-MM concentration has increased with the gestational age, and was inversely correlated with the age of the newborns among unaffected specimens. CK-MM on dry blood spot filter paper can be stable for 14 days at 2-8℃. Statistical analysis of CK-MM value of the 10 252 neonates suggested that the threshold may be set as 700 ng/mL. Exonic deletions were found in 2 confirmed cases, whose CK-MM level was greater than 2000 ng/mL. CONCLUSION Detection of CK-MM in dry blood spot filter paper has provided an effective method for newborn screening of DMD. This simple and inexpensive method can be used for large-scale screening, which is of great value to the early intervention and treatment of the disease.

OBJECTIVE: To explore the clinical phenotype and genetic basis for a fetus suspected for Coffin-Siris syndrome. METHODS: Chromosomal microarray analysis (CMA) and whole exome sequencing (WES) were carried out for the fetus. Candidate variant was verified by Sanger sequencing. RESULTS: Prenatal ultrasound at 23rd gestational week has revealed fetal ventriculomegaly. No abnormality was found by CMA, while WES revealed that the fetus has harbored a de novo heterozygous c.2851G>A (p.G951R) variant of the SMARCA4 gene, which was predicted to be pathogenic. CONCLUSION Genetic testing should be considered for fetuses featuring progressive widening of lateral cerebral ventricles.
