Expressions of survivin, p53 and human epidermal growth factor receptor 2 in breast cancer tissues and their prognostic value / 肿瘤研究与临床

Objective:To investigate the expressions of apoptosis-related factors survivin, p53 and human epidermal growth factor receptor 2 (HER2) in breast cancer tissues and their prognostic value.Methods:A total of 131 patients undergoing radical mastectomy for breast cancer who were admitted to Tangshan Maternal and Child Health Care Hospital from February 2015 to January 2019 were selected as the research subjects. During the operation, the cancer tissues and adjacent tissues (normal tissues >3 cm from the tumor margin) were collected from the patients. Expressions of survivin, p53 and HER2 in cancer tissues and adjacent tissues of patients were detected by using immunohistochemistry. The prognoses of patients were recorded after the follow-up for 3 years; the recurrence, metastasis and death treated as the poor prognosis, the rest prognoses of patients were treated as the good prognosis group. The difference of clinicopathological characteristics between the poor prognosis group and the good prognosis group was compared. Multivariate logistic regression was used to analyze risk factors for prognosis of breast cancer patients. The result of prognosis of breast cancer was taken as the golden standard. The receiver operating characteristic (ROC) curve was used to analyze the value of survivin pasitive, p53 pasitive, HER2 pasitive alone, the combination of both and the combination of the there in the judgement of poor prognosis of breast cancer.Results:The positive expression rates of survivin [49.6% (65/131) vs. 7.6% (10/131)], p53 [60.3% (79/131) vs. 13.0% (17/131)] and HER2 [79.4% (104/131) vs. 16.8% (22/131)] in cancer tissues were higher than those in adjacent tissues (all P<0.001). A total of 131 breast cancer patients were followed up for 3 years without any loss of follow-up, and the follow-up rate was 100%. Within the follow-up for 3 years, there were 15 (11.5%) cases of recurrence, 8 (6.1%) cases of metastasis, and 10 (7.6%) cases of death, the incidence of poor prognosis was 25.2% (33/131); and the remaining 98 cases had good prognosis. The proportions of patients with TNM stage Ⅲ, lymph node metastasis, poorly differentiated histology, tumor diameter ≥3 cm, survivin, p53, and HER2 positive expressions in the poor prognosis group were higher than those in the good prognosis group (all P<0.05). Multivariate logistic regression analysis showed that TNM stage Ⅲ [ OR = 5.323 (95% CI 2.190-12.936)], lymph node metastasis [ OR = 4.773 (95% CI 1.964-11.600)], tumor diameter ≥3 cm [ OR = 3.582(95% CI 1.474-8.706)], positive survivin [ OR = 2.740 (95% CI 1.127-6.659)], positive p53 [ OR = 3.271 (95% CI 1.346-7.949)], and positive HER2 [ OR = 3.873 (95% CI 1.594-9.412)] were independent risk factors for prognosis of breast cancer (all P<0.001). The ROC curve results showed that the area under the curve (AUC) values of survivin positive, p53 positive,HER2 positive, and the combination of any two were more than 0.80 (all P<0.001); the AUC of the combination of the three was 0.944 (95% CI 0.890-0.977) ( P<0.001). Conclusions:The expressions of survivin, p53, and HER2 are highly expressed in breast cancer tissues. The expressions of the three can be used to judge the prognosis of breast cancer patients, and the combination of the three has a higher judgement value.

Analysis of genotypes on 850 newborns with SLC26A4 single-allele mutation and the phenotypes of those with second variant / 中华耳鼻咽喉头颈外科杂志

Objective: To clarify the phenotypes of the newborns with SLC26A4 single-allele mutation in deafness genetic screening and second variant; to analyze the SLC26A4 genotype and hearing phenotype. Methods: 850 newborns born in Beijing from April 2015 to December 2019 were included and there were 468 males and 382 females. They received genetic deafness screening for 9 or 15 variants, with the result of SLC26A4 single-allele mutation. Firstly, three step deafness gene sequencing was adopted in this work, i.e., the first step was "SLC26A4 gene whole exons and splice sites" sequencing; the second step was "SLC26A4 gene promoter, FOXI1 gene and KCNJ10 gene whole exons" sequencing; and the third step was detection for "SLC26A4 gene copy number variation". Secondly, we collected the results of newborn hearing screening for all patients with the second mutation found in the three step test, and conducted audiological examinations, such as acoustic immittance, auditory brainstem response and auditory steady state response. Thirdly, for novel/VUS mutations, we searched the international deafness gene database or software, such as DVD, ClinVar and Mutation Taster, to predict the pathogenicity of mutations according to the ACMG guideline. Lastly, we analyzed the relationship between genotype and phenotype of newborns with SLC26A4 single allele mutation. Results: Among 850 cases, the median age of diagnosis was 4 months. In the first step, 850 cases were sequenced. A total of 32 cases (3.76%, 32/850) of a second variants were detected, including 18 cases (2.12%, 18/850) with identified pathogenic variants; 832 cases were sequenced and 8 cases of KCNJ10 gene missense variants were detected among the second step. No missense mutations in the FOXI1 gene and abnormal SLC26A4 gene promoter were detected; the third step sequencing results were all negative. Genotypes and hearing phenotypes included 18 cases combined with the second clear pathogenic variant, 16 cases (16/18) referred newborn hearing screening and 2 cases (2/18) passed in both ears; degree of hearing loss consisted of 18 profound ears (18/36), 13 severe ears (13/36) and 5 moderate ears (5/36); audiogram patterns comprised 17 high frequency drop ears (17/36), 14 flat ears (14/36), 3 undistinguished ears (3/36), and 2 U shaped ears (2/36); 11 cases underwent imaging examination, all of which were bilateral enlarged vestibular aqueduct. As for 22 cases of other genotypes, all passed neonatal hearing screening and the hearing diagnosis was normal, including 9 cases with VUS or possibly novel benign variants, 8 cases with KCNJ10 double gene heterozygous variants, and 5 cases with double heterozygous variants. Conclusions: The probability of individuals with SLC26A4 single-allele variant who merge with a second pathogenic variant is 2.12%, all of which are SNV, which can provide scientific basis for the genetic diagnosis and genetic counseling of SLC26A4 variants. Those who have merged with second pathogenic variant are all diagnosed with sensorineural hearing loss. Patients with KCNJ10 gene mutations do not manifest hearing loss during the infancy, suggesting the need for further follow-up.

Modified strict sperm morphology threshold aids in the clinical selection of conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) / 亚洲男科学杂志(英文版)

For infertility treatment, the selection of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is decided by multiplying indicators (including fallopian tube factors, semen count, and semen motility), except for sperm morphology. In this study, we conducted a retrospective analysis, from implantation to birth, over a period of 5 years. A total of 1873 couples with primary or secondary fallopian tube factors and an increased defective sperm morphology rate (DSMR) were divided into different groups to receive IVF or ICSI cycles. By comparing the outcomes, we found that the F1 group (DSMR <96%, IVF group 1) had higher cleavage rate, biochemical pregnancy rate, clinical pregnancy rate, and live birth rate than the F3 group (DSMR >98%, IVF group 3; P < 0.05). In contrast, there was no significant difference in the ICSI subgroups. Furthermore, a comparison of the outcomes between IVF and ICSI showed that the S3 group (DSMR >98%, ICSI group 3) had higher cleavage rate (P < 0.001), biochemical pregnancy rate (P < 0.05), clinical pregnancy rate (P < 0.05) and live birth rate (P < 0.05) than the F3 group. However, the ICSI subgroup had a lower two pronuclei fertilization rate than the IVF subgroup (P < 0.05). Our data suggest that the sperm morphology should also be considered when selecting IVF or ICSI combined with other semen parameters before the first assisted reproductive technologies (ART) cycle, especially for males with severe sperm defects.

OBJECTIVE：To evaluate the dissolution behavior consistency between the generic drugs and original drugs of Oxcarbazepine scored tablets ，and to compare the appearance ，the friability of the split portions ，loss of mass of the split portions as well as crystal form and morphology of raw material from different enterprises. METHODS ：HPLC method was adopted. The paddle method （rotation speed of 60 r/min，the temperature of 37.0℃）was adopted to determine accumulative dissolution rate of generic and original drugs in 4 mediums [ 0.6％ SDS hydrochloric acid solution （pH＝1.2），0.6％ SDS acetate buffer solution （pH＝4.5），0.6％ SDS phosphate buffer solution （pH＝6.8）and 0.6％ SDS water solution]. The similarity factor method was used to evaluate the similarity of dissolution curves as well as intra-batch uniformity of the split portions and whole tablets. The friability tester and electronic balance were used to determine the friability and the loss of mass of the split portions. X-ray diffractometer and scanning electron microscope were used to observe the crystal form and crystal morpho logy of the raw materials of different enterprises. RESULTS ：The linear range of oxcarbazepine was LOD was 0.04 μg/mL；RSDs of precision ，stability，reprodu- cibility and durability tests were lower than 2.0％；the reco- veries were 99.80％-101.63％（RSD＝0.37％-0.91％，n＝3）. The average cumulati ve dissolution rate of generic drug A ， generic drug B and original drug in 4 different dissolution media at 90 min were 92％，87％，90％ [0.6％ SDS hydrochloric acid solution（pH＝1.2）]；94％，94％，90％ [0.6％ SDS acetate buffer solution （pH＝4.5）]；95％，95％，91％ [0.6％ SDS phosphate buffer solution （pH 6.8）]；97％，98％，95％（0.6％ SDS water solution ）. The similarity factors of generic drug A ，generic drug B and original drug in 4 kinds of different dissolution media were 66 and 81，71 and 69，71 and 61，59 and 39. In the first 15 min，the difference of dissolution rate of split portions and whole tablets were －3％-13％，－2％-24％ and －3％-7％ for generic drug A ， generic drug B and original drug ，respectively. RSDs of accumulative dissolution rate of split portions and whole tablets were 6％-14％ and 2％-9％ for generic drug A （n＝12），4％-10％ and 1％-8％ for generic drug B （n＝12）and 2％-7％ and 2％-8％ for original drug. The appearance of the original drug was fusiform ，and the notch was deep ；the shape of the generic drug was different from each other ，and the notch of the generic drug was significantly shallower than that of original drug. The friability ， the loss of mass of the split portions for generic drug A and generic drug B ，original drug were 0.62％and 0.67％，0.12％ and 0.11％，0.08％ and 0.05％. The domestic raw materials possessed irregular lumps and debris ，while the raw materials produced by original drug enterprises possessed regular flat cuboids and regular strips with little debris ；but X-ray diffraction peaks of them were basically the same. CONCLUSIONS ：The dissolution behavior of generic drug A in 4 medium is consistent with that of the original drug；dissolution behavior of generic drug B in water containing 0.6％SDS is different from that of the original drug ；there is no significant change in the homogeneity of the original drug before and after splitting ，but the homogeneity of the generic drug A and B after splitting is lower than that of the whole tablet ；the fragility of generic drugs and loss of mass of split portions are higher than those of the original drugs ；two kinds of raw material have the same crystal form but different crystal morphology.

Understanding Taiwanese Women's Decisional Experiences Regarding Prenatal Screening Procedures And Diagnostics: A Phenomenological Study

Purpose@#This study sought to understand Taiwanese women’s decisional experiences regarding prenatal screening procedures and diagnostics. @*Methods@#A hermeneutic phenomenological design guided semistructured interviews with 33 women who were 36 weeks pregnant. Data were collected between February and October 2016. Verbatim transcripts were analyzed following hermeneutic circle to cocreate an understanding of Taiwanese women’s decision-making in prenatal screening and diagnostics. @*Results@#Women’s existential experiences were derived from their decision-making process on prenatal screening procedures and diagnostics for chromosomal aneuploidy. These decisional experiences were captured by four theme clusters and eight themes, which were inductively derived from 16 meaning units: (1) accessing health information; (2) considering what was best for my baby; (3) considering family finance; and (4) feeling anxiety posttest. @*Conclusion@#Participants made informed choices on several prenatal screening procedures, ostensibly, based on their personal values and considerations. During the decision-making process, often-cited benefits of genetic screenings were emphasized, but test limitations were often unheeded. A fundamental need for supportive information in decision making was further identified with recommended strategies. Hence, a revision of traditional genetic counseling approaches is recommended. As genomics technologies are increasingly available during antenatal services, women should be sufficiently educated about them to support decision making.

Genome cloning and genetic diversity of Apple chlorotic leaf spot virus

Apple chlorotic leaf spot virus (ACLSV) with a wide distribution and variability is great threat to apple yield and quality. The systematic research on the occurrence, genetic structure and evolutionary mechanism is important for the prevention of ACLSV. In this study, 360 apple leaf samples were collected from Shanxi province and tested by RT-PCR, and the result showed that the incidence of ACLSV in Shanxi was ranged from 43.59% in Linfen to 68.18% in Wanrong. One new ACLSV isolate (shanxi14-MK368727) was collected from the positive samples, of which the genome (including the 5' and 3' ends) was 7507 bp and encoded 2536 amino acids. Compared with online database, the highest nd identity was between shanxi14 and KJ522693.1, and the lowest was shanxi14 and M58152.1. Phylogenetic analyzed based on genome showed that 25 isolated of ACLSV were divided two groups (Group I and II), which showed that was no significant correlation with geographic location. The selection pressures of POL, MP and CP were tested, the result proved the three genes were under negative selection pressure. The knowledge presented in this study will be useful in for the design of long-term, sustainable management strategies for controlling these viruses.

@#AIM: To investigate the effects of intravitreal injection of conbercept-assisted vitrectomy(PPV)on proliferative diabetic retinopathy(PDR)and inflammatory factors and angiopoietin-like protein 4(ANGPTL4)in the vitreous. <p>METHODS: Totally 90 patients with PDR(99 eyes)who underwent PPV treatment in our hospital from January to February 2018 were selected as subjects, and were divided into PPV group and IVC/PPV group according to whether intravitreal injection of conbercept(IVC).The surgical indexes of the two groups, the best corrected visual acuity(BCVA, LogMAR)and the incidence of postoperative vitreous hemorrhage(POVCH)were observed within 3mo after surgery were observed. The levels of interleukin-6(IL-6), interleukin-10(IL-10), C-reactive protein(CRP)and other inflammatory factors and ANGPTL4 in the vitreous of the two groups were measured.<p>RESULTS: In the IVC-assisted PPV group, the operation time, intraoperative severe hemorrhage(bleeding with electrocoagulation pen), iatrogenic retinal tears and postoperative silicone oil filling rate were significantly better than those in the PPV group(<i>P</i><0.05). There was no significant difference in BVCA between the two groups(<i>P</i>>0.05). There was no significant difference in BVCA between the two groups(<i>P</i>>0.05). At 1 and 3mo after operation, BCVA decreased significantly in both groups. Visual acuity improved significantly. The BCVA(LogMAR)of the IVC combined with the PPV group was significantly lower than that of the group. Simple PPV group(<i>P</i><0.05). The occurrence of POVCH The rate was significantly decreased(<i>P</i><0.05), the contents of IL-6, IL-10 and CRP in the vitreous were significantly decreased(<i>P</i><0.05), and the content of ANGPTL4 was significantly increased(<i>P</i><0.05).<p>CONCLUSION: Preoperative vitreous injection of conbercept in the treatment of PDR can reduce the occurrence of intraoperative and postoperative complications, promote the recovery of visual acuity, reduce the inflammatory response in the vitreous and increase the content of ANGPTL4.
