ABSTRACT

Objective:To investigate the diagnostic value of serum miRNA-9-5p (miR-9-5p), miRNA-21-5p (miR-21-5p) and miRNA-3923 (miR-3923) in patients with cervical cancer.Methods:The data of 100 cervical cancer patients in Shanxi Provincial Cancer Hospital from July 2016 to June 2018 (the experimental group) and 100 healthy subjects (the healthy control group) during the same period were collected. The real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) combined with probe hybridization was used to detect the expression levels of human papillomavirus (HPV) E6/E7 mRNA in paraffin-embedded tissues of patients with cervical cancer and in cervical exfoliated cells of the healthy control people. Ct value ≤ 40 cycles was considered as HPV E6/E7 positive. Serum samples from 3 patients with cervical cancer and 3 healthy people were taken out; microRNA (miRNA) Array was used to detect the expression level of 384 miRNA; the differential expression of miRNA was screened out and cluster analysis was performed, and then the screened miRNAs was verified by using qRT-PCR. Finally, the receiver operation characteristics (ROC) curves of screened miRNAs alone and HPV E6/E7 alone or the combination of three miRNAs and HPV E6/E7 in the diagnosis of cervical cancer were drawn to make comparison of diagnostic efficacy.Results:Among the paraffin-embedded tissues from 100 patients with cervical cancer, there were 65 cases (65%) HPV E6/E7 positive; in the healthy control group, HPV E6/E7 in cervical exfoliated cells of 100 people was negative. A total of 248 differentially expressed miRNAs were detected from the serum samples in 3 patients with cervical cancer and 3 healthy people. The cluster analysis finally identified 16 abnormally regulated miRNAs. qRT-PCR verification confirmed that differences in the expression levels of miR-9-5p, miR-21-5p and miR-3923 in the healthy control group and cervical cancer group were statistically significant (all P < 0.01), and then the three were selected to make diagnosis of cervical cancer. The expression levels of miR-9-5p, miR-21-5p and miR-3923 in HPV E6/E7 positive cervical cancer group were higher than those in the healthy control group (all P < 0.05), expression levels of miR-21-5p and miR-3923 in HPV E6/E7 negative cervical cancer group were increased ( P = 0.008, P = 0.038); expression levels of the three miRNAs in HPV E6/E7 positive group were higher than those in HPV E6/E7 negative group (all P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of miR-3923 was the biggest (0.843), the specificity was the highest (82%, the cut-off value was 2.88) and the sensitivity of miR-21-5p was the highest (85%, the cut-off value was 4.08) when miR-9-5p, miR-21-5p and miR-3923 were respectively applied to diagnose the cervical cancer; AUC (0.924), the sensitivity and the specificity (85%, 94%; the cut-off value was 4.04) of the combination of the three indicators were higher than those of the single indicator in the diagnosis of cervical cancer. AUC was 0.766 when HPV E6/E7 was kused alone to diagnose. The diagnostic efficacy of HPV E6/E7 combined with miR-9-5p, miR-21-5p, miR-3923 respectively was further improved, the corresponding AUC was 0.914, 0.848, 0.932, respectively; the diagnostic efficacy of the combination of the four indicators was the highest (AUC was 0.942). Conclusion:miR-9-5p, miR-21-5p and miR-3923 may be helpful in the diagnosis of cervical cancer.

ABSTRACT

Estrogen receptor (esr) mediates the effects of estrogen on the expression of related genes, thereby regulating the growth and reproduction of mammals. To investigate the effect of retrotransposon insertion polymorphism (RIP) of the porcine esr gene on porcine growth performance, retrotransposon insertion polymorphism of the esr gene were predicted by comparative genomics and bioinformatics, and PCR was used to verify the insertion polymorphisms in different porcine breeds. Finally, the correlation analysis between the genotypes and performance of Large White pigs was conducted. The results showed that four retrotransposon polymorphic sites were identified in the esr1 and esr2 genes, which are esr1-SINE- RIP1 located in intron 2 of the esr1 gene, esr1-LINE-RIP2 and RIP3-esr1- SINE located in intron 5 of the gene, and esr2-LINE-RIP located in intron 1 of the esr2 gene, respectively. Among them, insertion of a 287 bp of SINE into intron 2 of the esr1 gene significantly affected (P<0.05) the live back fat thickness and 100 kg body weight back fat thickness of Large White pigs. Moreover, the live back fat thickness and back fat thickness at 100 kg body weight of homozygous with insertion (SINE+/+) was significantly greater than that of heterozygous with insertion (SINE+/-) and homozygous without insertion (SINE-/-). Therefore, esr1-SINE-RIP1 could be used as a molecular marker to assist the selection of deposition traits in Large White pigs.

ABSTRACT

Objective:In this study, the clinical data of biliary atresia(BA) and infant intrahepatic cholestasis(IHC) was reviewed, and the utility of gamma-glutamyl transpeptidase(GGT) and liver Young′s modulus in the differential diagnosis of BA and IHC in infants was discussed.Methods:Based on the clinical data of 120 infants with cholestasis treated in the Children′s Hospital Affiliated to Xi′an Jiaotong University, from September 2017 to December 2019, the infants were divided into two groups according to the results of intraoperative cholangiography and follow-up: BA group( n=50); IHC group( n=70). The age, clinical manifestations, laboratory examination results, gallbladder contraction rate, hepatobiliary scintigraphy, liver Young′s modulus, and medical treatment effects were compared between the two groups.The utility of GGT and liver Young′s modulus in the differential diagnosis of BA and IHC was analyzed. Results:The age, alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bile acid, fasting blood glucose, blood ammonia and splenomegaly between the two groups were compared and the results showed no statistical significance( P>0.05). In contrast, there were statistically significant differences( P<0.001) in stool color, liver size, total bilirubin(TB), direct bilirubin(DB), GGT, liver Young′s modulus, positive hepatobiliary scintigraphy, gallbladder contraction rate at 1 hour after meal, and medical treatment effect between the two groups.TB, DB, GGT, liver Young′s modulus and GGT combined with liver Young′s modulus were analyzed using ROC curves, and the area under the curve(AUC) were 0.820, 0.809, 0.906, 0.876 and 0.926, respectively.When GGT exceeded the cut-off value of 198.85 U/L, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of BA were 82.0%, 84.3%, 78.8%, 86.8% and 83.3%, respectively.When liver Young′s modulus exceeded the cut-off value of 8.6 kPa, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of BA were 88.0%, 80.0%, 75.9%, 90.3% and 83.3%, respectively.The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of GGT combined with liver Young′s modulus in diagnosing BA were 98.0%, 68.6%, 69.0%, 98.0% and 80.8%, respectively.Multivariate logistic regression analysis found that DB>115.55 μmol/L, GGT>198.85 U/L, and liver Young′s modulus>8.6 kPa were risk factors for BA( OR=9.510, P=0.001; OR=24.634, P<0.001; OR=21.469, P<0.001). Conclusion:GGT and liver Young′s modulus are useful in the differential diagnosis of BA and IHC.If GGT and liver Young′s modulu sexceed the threshold values of 198.85 U/L and 8.6 kPa respectively, it can effectively indicate that the child is BA.

There was no significant difference in the serum FSH peak value between the EP-RPP group and the RPP group( P>0.05). (2)The serum IGF-1 levels of the healthy control group, EP-SPP group, EP-RPP group, CPP group and RPP group were 166.00(126.50-188.00) μg/L, 199.00(170.50-262.50) μg/L, 252.00(233.00-291.50) μg/L, 288.00(252.00-376.00) μg/L and 382.00(264.0-499.50) μg/L, respectively.The serum IGF-1 levels of the EP-SPP group, EP-RPP group, CPP group and RPP group were all significantly higher than those in the healthy control group (all P<0.05). The serum IGF-1 levels in the EP-RPP group were higher than those in the EP-SPP group( P<0.01). As the puberty rapidly progressed, the serum IGF-1 levels gradually increased.The RPP group had the highest IGF-1 levels, and the difference in IGF-1 levels between the RPP group and EP-RPP group was statistically significant( P<0.01). (3)The serum DHEAS levels were 41.65(14.80-59.88) μg/L in the healthy control group, 42.50(30.15-79.83) μg/L in the EP-SPP group, 52.32(43.08-98.54) μg/L in the CPP group, 63.30(34.00-81.55) μg/L in the EP-RPP group and 70.89(51.85-100.02) μg/L in the RPP group.The DHEAS levels of the healthy control group, EP-RPP group and RPP group gradually increased.The RPP group had the highest DHEAS levels.There was significant difference in DHEAS levels among the healthy control group, EP-RPP group and RPP group ( P<0.05). There was no significant difference in DHEAS levels among the EP-SPP group, CPP group and EP-RPP group( P>0.05). (4)The serum AMH and BMP-6 levels in the EP-RPP group, EP-SPP group, RPP group, CPP group and healthy control group were not significantly different( P>0.05). (5)The area under the ROC curve of serum IGF-1 levels was 0.765, the cut-off value was 232.5 μg/L, the specificity for the cut-off value was 83.30%, and the sensitivity was 75.00%.The combined area under the ROC curve of the serum FSH peak value and the ratio of serum FSH/LH peak values was 0.795. Conclusions:Serum IGF-1 levels and the combination of the serum FSH peak value and the ratio of serum FSH/LH peak values can be used as effective indicators of slowly and rapidly progressive puberty in early adolescent girls.Serum DHEAS cannot be used as an early warning index of RPP, but it plays a critical role in the regulation of puberty initiation and process.Serum DHEAS levels may be related to the Tanner stage.

Objective:To investigate the clinical and genetic characteristics of a boy with Ulnar-Mammary syndrome(UMS), and to review the literature.Methods:The clinical and genetic data of a boy with UMS, who was admitted to the Department of Endocrinology, Genetics and Metabolism, Children′s Hospital of Soochow University in May 2018 were analyzed. Original papers on UMS published up to July 2019 were retrieved.Results:A male patient at the age of 12 years and 8 months visited us for growth retardation. He presented with high forehead, epicanthic folds, broad nasal tip, anteverted nostrils, high palate, dental crowding, mammary gland hypoplasia, and absence of axillary hairs, with height 148.9 cm(<-1 SD). Growth hormone stimulation test indicated growth hormone deficiency(growth hormone peak <5 ng/ml). After one year of treatment with recombinant human growth hormone, his height was improved. Gene sequencing identified a de novo heterozygous mutation of TBX3 c. 711DelC(p.N238Mfs* 4). According to ACMG guidelines in 2015, the mutation is pathogenic and has not been reported in the above databases.However, this mutation was not detected in his parents.Conclusion:UMS should be considered in dwarfism with special face, dysplasia of external genitalia, sweat glands, and mammary glands, and TBX3 is a pathogenic gene.

ABSTRACT

Objective:To investigate the expression and clinical significance of long non-coding RNA (lncRNA) H19 and lncRNA maternally expressed gene 3 (MEG3) in the serum of patients with gastric cancer (GC).Methods:A total of 87 GC patients admitted to the First People′s Hospital of Suqian (July 2017 to August 2018) were selected as the GC group, 51 patients with benign tumors as the benign tumor group, and 40 healthy people with physical examination as the healthy control group. The expression levels of lncRNA H19 and lncRNA MEG3 in serum were measured; the relationship between the expression levels of the two and clinicopathological features and prognosis of patients with GC was analyzed.Results:The levels of serum lncRNA H19 in healthy control group, benign tumor group and GC group were gradually increased, and lncRNA MEG3 level was gradually decreased ( P<0.05); the serum lncRNA H19 level in GC group was related to tumor invasion depth, tumor node metastasis (TNM) stage and lymph node metastasis. The level of lncRNA MEG3 was related to the degree of differentiation, TNM stage and lymph node metastasis ( P<0.05). Among the 87 GC patients , 63 patients were followed up for 13-32 months with an average of (23.54±4.18)months. Kaplan Meier survival curve showed that the overall survival rate of high serum lncRNA H19 group and low serum lncRNA MEG3 level group was significantly lower than that of low serum lncRNA H19 level group and high serum lncRNA H19 level group. Multivariate Cox regression analysis showed that lncRNA H19 ( HR=3.442, 95% CI=0.089-23.421) was an independent prognostic factor for GC patients, and lncRNA MEG3 ( HR=4.386, 95% CI=0.934-20.596) was a protective factor ( P<0.05); receiver operating characteristic (ROC) curve showed that the sensitivity, specificity and accuracy of serum lncRNA H19+ lncRNA MEG3 [area under curve (AUC)=0.922, 95% CI=0.861-0.962] were higher than those of serum lncRNA H19 (AUC=0.840, 95% CI=0.771-0.904) and lncRNA MEG3 (AUC=0.830, 95% CI=0.753-0.890). Conclusions:The level of serum lncRNA H19 in GC patients is significantly increased, and the level of lncRNA MEG3 is significantly reduced, which is closely related to tumor occurrence, development and prognosis. Combined detection of the two can enhance the diagnostic value of GC.

ABSTRACT

Objective:To investigate the clinical effect of ethinylestradiol cycloproterone combined with metformin in the treatment of polycystic ovary syndrome (PCOS) with insulin resistance.Methods:Ninety PCOS patients with insulin resistance admitted to the First People's Hospital of Taizhou from May 2017 to May 2019 were selected in the study.According to the random number table method, the patients were divided into control group and treatment group, with 45 cases in each group.The control group was treated with ethinylestradiol and cycloprogesterone, while the observation group was treated with ethinylestradiol and cycloprogesterone combined with metformin.The clinical effects of two groups were compared, including estradiol (E 2), testosterone (T), luteinizing hormone (LH), follicle stimulating estrogen (FSH), insulin resistance index (HOMA-IR), fasting plasma glucose (FPG) before and after treatment.Body mass index (BMI) and fasting insulin (FINS) levels were measured.The ovulation, pregnancy, menstrual recovery and adverse reactions of the two groups were analyzed. Results:The total effective rate of the treatment group (97.77%) was significantly higher than that of the control group (77.77%), the difference was statistically significant (χ 2=8.389, P=0.003). Before treatment, there were no statistically significant differences in E 2, T, LH, FSH between the treatment group and the control group (all P>0.05). After treatment, the levels of E 2[(112.90±18.90)pmol/L], T[(1.30±0.78)nmol/L], LH[(8.00±1.50)U/L]and FSH[(1.20±0.39)U/L] in the treatment group were significantly lower than those in the control group[E 2(128.90±19.95) pmol/L, T(2.19±1.00) nmol/L, LH(11.65±1.60)U/L and FSH(1.89±0.50)U/L], the differences were statistically significant( t=3.905, 4.707, 10.871, 7.299, all P<0.05). Before treatment, the levels of HOMA-IR, FPG, BMI and FINS between the two groups had no statistically significant differences(all P>0.05). After treatment, the levels of HOMA-IR (2.19±0.50), FPG[(4.30±1.19)mmol/L], BMI[(22.40±1.89)kg/m 2], FINS[(15.98±5.00)mU/L] in the treatment group were significantly lower than those in the control group[HOMA-IR(3.90±0.58), FPG (6.09±1.20) mmol/L, BMI (24.69±4.60)kg/m 2, FINS (19.00±6.89)mU/L], the differences were statistically significant( t=14.979, 7.105, 3.089, 2.379, all P<0.05). The ovulation, pregnancy and menstrual recovery in the treatment group were significantly higher than those in the control group (χ 2=4.121, 4.285, 10.000, all P<0.05). The incidence of adverse reactions in the treatment group (13.33%) was significantly lower than that in the control group (37.77%), the difference was statistically significant between the two groups (χ 2=7.066, P=0.007). Conclusion:Ethinylestradiol cycloproterone combined with metformin in the treatment of PCOS with insulin resistance has significant clinical efficacy, can alleviate the endocrine metabolic disorders and insulin resistance, it is worthy of clinical application and promotion.

ABSTRACT

Objective:To explore the status quo of alexithymia, ruminant thinking and depression in infertility patients and their relationship.Methods:A cross-sectional survey was conducted among infertile patients who visited the reproductive center of the First Affiliated Hospital of Nanjing Medical University from September to December 2018. The data were analyzed by descriptive analysis, t-test, variance analysis and path analysis. Results:There was a moderate positive correlation between depression score (13.17 ±8.66), alexithymia score (51.62±10.91) and ruminant thinking score (18.28±10.65) in infertile patients ( r values were 0.442, 0.551, 0.569, all P < 0.05). Alexithymia played a mediating role between ruminant thinking and depression in infertile patients, and its indirect effect was 0.026 4, accounting for the total effect 24.81%. Conclusions:The depression status of infertility patients is not optimistic. Ruminant thinking has a great impact on infertility patients through alexithymia. The inner feelings of infertility patients can not be effectively expressed. It is easy to form negative emotional stress, which leads to depression. Medical staff and family members should pay attention to the ruminant thinking of patients' inner thoughts and timely dumping. Hearing and counseling can promote the physical and mental recovery of patients.

ABSTRACT

Objective:To investigate the cause of missed diagnosis by transthoracic echocardiography (TTE) based on the characteristics of partial anomalous pulmonary venous connection (PAPVC), and to improve the ultrasonic diagnostic accuracy of PAPVC in children.Methods:The TTE results of 252 children under 12 years old who were confirmed with PAPVC at Guangdong Provincial People′s Hospital from January 2011 to June 2019 were reviewed retrospectively.The types of PAPVC and the associated atrial septal defects (ASD) as well as the confirmed and missed cases by TTE were analyzed.Results:PAPVC was right-sided in 238 patients (94.4%), left-sided in 8 patients (3.2%), and bilateral in 6 patients (2.4%). There were 177 cases (70.2%) whose pulmonary veins were abnorma-lly connected to the right atrium(RA), 37 cases (14.7%) to the junction of the RA and the superior vena cava (SVC), 27 cases (10.7%) to the distal SVC, and 6 cases (2.4%) to the inferior vena cava.Besides, pulmonary veins of 5 cases (2.0%) flew back to the RA through the coronary sinus.One hundred and ninety PAPVC cases were combined with sinus venous defects (SVD) and 53 cases combined with secondum ASD.Two hundred and twenty-one cases were accurately diagnosed while 31 cases were underestimated by TTE.The omission diagnostic rates of right superior pulmonary veins connecting to the distal SVC, 1 or 2 right pulmonary veins connecting to the RA or the junction of the RA and SVC, and left-sided PAPVC were 8 out of 18 (44.4%), 22 out of 215 (10.2%) and 1 out of 8 (12.5%), respectively.Among 54 cases with right superior pulmonary veins anomalously connected to the RA or the junction of the RA and SVC, 88.9% of them (48/54 cases) were combined with superior SVD.Among 161 cases with the right inferior pulmonary veins or 2 right pulmonary veins connected to the RA, 78.2% of them (126/161 cases) were combined with inferior SVD.There were statistically significant differences in ASD types between the 2 right-sided PAPVC groups.Conclusions:SVD is often associated with 1 or 2 right pulmonary veins connected to the RA or the junction of the RA and SVC.The cases with right superior pulmonary veins connected to the distal SVC are prone to be underestimated by TTE.Whether there is abnormal blood flowing into SVC should be noticed during superior sternal fossa examinations.Each pulmonary vein should be examined in detail in the TTE test and accurate diagnosis of PAPVC can be made in most cases.
