Based on the study of solid cancer incidence in survivors of the atomic bomb disaster (atomic bomb survivors) from 1958 to 1998, the Radiation Effects Research Foundation (RERF) performed an additional 11-year follow-up (1999—2009) to further investigate the 50-year solid cancer incidence of atomic bomb survivors from 1958 to 2009. Considering influencing factors such as gender, smoking, drinking, body mass index, and medical exposure, we updated the radiation risk estimate for solid cancer and found a new problem of the relationship between gender-specific dose response, exposure age and cancer incidence during the study, which provides guidance for future research.

Objective:To explore the clinical application value of extended detection method for Y chromosome azoospermia factor (AZF) microdeletion in hereditary infertility and sexual development disorders.Methods:Multiplex polymerase chain reaction(PCR) combined with agarose gel electrophoresis method, combined fluorescence multiplex PCR capillary electrophoresis DNA fragment analysis technique and chromosome karyotype analysis technique were used to detect an infertility patient who visited the Reproductive Center of Henan Provincial People's Hospital in March 2020 (patient 1) and a child with sexual dysplasia who visited the Endocrinology Department of Henan Provincial People's Hospital in June 2020 (patient 2).Results:We found no AZF microdeletions on the Y-chromosome of the two patients to detect 15 sequence tagged site (STS) sequences. To detect the 27 genetic markers, it was found that in patient 1 the amplification peak of the STS locus on the long arm of the X chromosome was nearly three times as much as the amplification peak of the short arm of the X chromosome (Xqp), the STR quality control loci on the long arm of the X chromosome had two peaks, and the ratio was about 2∶1 (GATA31E08 and DXS6809), and the ratio of the amplification peak of the long arm of the X chromosome to that of the autosome at the TAF9b locus was about 3∶2. Patient 1 might have an abnormal copy number of long arm of X chromosome. In patient 2, the ratio of the amplification peak of C03Yp, TAF9b, C01Yq and C11Xp on the X chromosome or Y chromosome to the amplification peak of autosomes was about 1∶1, and the amplification peak of the STR quality control site on the X chromosome was two peaks, and the ratio was about 1∶1 (GATA31E08 and DXS6795). Patient 2 might have abnormal X and Y chromosome copy numbers. The results of karyotype analysis showed that the karyotype of patient 1 was 47, XY, i(X)(q10); the karyotype of patient 2 was 48, XXYY, which was consistent with the results of AZF microdeletion extension test.Conclusion:Compared with the traditional AZF detection method, this extended detection method can not only meet the needs of AZF detection, but also indicate abnormal copy number of sex chromosomes. Compared with the karyotype analysis technology, it has the characteristics of simple operation and can reduce the cost and workload of clinical testing.

Background: An in vitro study on rapid culturing method of human gingival fibroblast cells (HGFCs) was established to investigate the potential use of the leukocyte-platelet rich fibrin (L-PRF) in tissue engineering technology, different medical fields, including periodontology and implantology. Methods: Eight biopsies were obtained from eight different donors and a modified culturing technique was developed to obtain HGFCs. The modified 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay was used to compare the cell viability when the modified culturing method was used in comparison to the standard method. Blood samples were collected from the same patients and L-PRF was isolated using a standard protocol. The releases of platelet-derived growth factor-AA and transforming growth factor-beta1 at various time intervals were observed using enzyme-linked immunosorbent assay (ELISA) kit. The proliferative effect of L-PRF on HGFCs was assessed by the cell counting kit—8 assay. Results: A simple and rapid modified method for in vitro HGFC culture yielded a cellular monolayer within three to nine days after cell culture. L-PRF with three-dimensional polymer fibers released growth factors that peaked during the first three hours and continued to produce up to 10 days. The L-PRF presented a dose-dependent effect on HGFCs proliferation where HGFCs proliferation increased with an increase in L-PRF concentration. Conclusion The modified technique for the culture of HGFCs might be useful for the development of future experimental and clinical studies, besides L-PRF has great therapeutic potential in oral surgery fields.

Objective: To investigate the efficacy and safety of ketogenic diet (KD) and antiepileptic drugs(AEDs) in the children with drug refractory Dravet syndrome (DS). Methods: Thirty-two cases of drug refractory DS were enrolled into the Department of Neurology, Shenzhen Children′s Hospital Affiliated to Shantou University Medical School from July 2016 to December 2017, and they were divided into 2 groups: KD group and AEDs group (16 cases for each group), respectively.KD was added to as an additional therapy for KD group, and oral AEDs were administered only in AEDs group.In KD group, oral AEDs were not adjusted for the first 3 months.AEDs could be adjusted within a limited range in 2 groups after 3 months.The clinical efficacy, improvement of cognitive function, retention rate and side effects were observed and compared after 3, 6, 12 months of treatment.The average monthly seizure frequency within 3 months before enrollment was recorded as the baseline.The clinical efficacy was assessed by comparing the seizure frequency of each observation period with the baseline. Results: In KD group, after 3, 6, 12 months′ follow-up, KD the-rapy was maintained in 15, 14, 12 patients.The number of patients whose seizure reduction over 50% was 10, 12, 11 cases, respectively.The number of patients whose seizure reduction over 90% was 7, 9, 10 cases, respectively.The number of patients who were seizure free was 3, 6, 8 cases, respectively.In AEDs group, after 3, 6, 12 months′ therapy, the number of patients whose seizure reduction over 50% was 6, 7, 8 cases, respectively, the number of patients whose seizure reduction over 90% was 3, 3, 4 cases, respectively.The number of patients who were seizure-free was 2, 1, 2 cases, respectively.There was a significant difference in the seizure reduction between 2 groups after 6, 12 months (P<0.05). Furthermore, the incidence of status epilepticus (SE) was significantly reduced in KD group, and non-fever related status epilepticus (NFSE) was preferentially improved.There was a significant difference in the incidence of SE between before and after treatment in the KD group (P<0.05). After 12 months, there was a significant difference in the incidence of SE between 2 groups (P<0.05). After 6, 12 months of treatment, the patients in KD group had significant improvements in adaption, gross motor and language quotients by Gesell Developmental Scale compared to the AEDs group (all P<0.05). Eleven of 12 children who adhered to the therapy for 1 year in KD group had improvement of developmental quotient ≥ 1 grade, however, 7 cases of 16 children in AEDs group had this improvement.The incidence of adverse effect in the KD group and the AEDs group was 37.5%(6/16 cases) and 56.3%(9/16 cases), respectively, and the difference was not significant (P>0.05). Conclusions KD can not only reduce seizure frequency and relieve SE, but also improve the cognitive function of drug refractory DS.The adverse reaction ratio of KD does not increase significantly compared to AEDs.Therefore, KD is effective and safe therapy for children with drug-resistant DS.

Objective To explore the applicable conditions for using urine plutonium monitoring data to assess personal internal doses,in order to provide references for the occupational health management and the urine plutonium monitoring in nuclear sector.Methods Using some plutonium mixtures from DOE nuclear facilities,as an example,the urine plutonium levels were estimated through simulation calculation at 1 mSv effective dose arising from either acute or chronic inhalation of plutonium compounds,respectively.The results were compared with the typical detection limit of radiochemical separation and α-spectrometry.The feasibility of urine plutonium monitoring for dose assessment of internal radiation exposure was discussed.Results Only for type M plutonium compunds,1 mSv detection limit can be achieved using radiochemical separation and α-spectrometry within 10 d after inhalation.Conclusions Before the monitoring plan of urine plutonium is made,detection limits of monitoring method should be considered.Internal dose could be accessed using workplace air monitoring and working hours when necessary.

OBJECTIVETo use combined G-banding and array-comparative genomic hybridization (aCGH) for the prenatal diagnosis of a fetus with 5q35 deletion syndrome.

METHODSChromosomal karotypes of the fetus and parents were analyzed with G-banding analysis. aCGH was performed to detect minor chromosomal structural abnormalities.

RESULTSThe karyotype of the fetus was ascertained as 46, XY, t(5;10)(q35;p13), and the karyotypes of the parents were normal. aCGH has identified a de novo 1.68 Mb deletion at 5q35.2q35.3 and a 1.44 Mb duplication at 10p14p13.

CONCLUSIONaCGH has a higher resolution and greater accuracy for mapping chromosomal aberrations and is a useful supplement for G banding karyptyping analysis.
