Objective To detect CD_(36) expressions in polycystic ovary (PCO), and to explore its correlation with local androgen and insulin at transcription level. Methods From August 2002 to February 2003, 12 patients with asymmetric PCO, 15 primary or secondary infertile patients without endocrine disorders and 8 polycystic ovary syndrome (PCOS) with bilateral PCO were recruited. Extraction of follicular fluid and detection of testosterone(T), dehydroepiandrosterone sulfate (DHEAS), insulin (INS) and androstenedione (A_2) were performed. Relative CD_(36) mRNA expression level of human ovarian inner thecal cells was analyzed by auto image analysis system (IAS) after RT-PCR. Results The level of CD_(36) mRNA expression in thecal cells was 0.24?0.07 in polycystic ovary of PCO group and 0.21?0.05 in bilateral ovaries of PCOS group, respectively, which were significantly lower than 0.83?0.13 in normal ovaries (P

OBJECTIVE:
To explore the genetic mechanism underlying a case with para-Bombay phenotype.
METHODS:
The ABO and Lewis phenotype were identified with serological methods. The coding regions of exons 6 and 7 of the ABO and FUT1 genes were amplified with PCR and directly sequenced. Haploid sequence analysis was carried out on the variant sites of the FUT1 gene.
RESULTS:
Serological analysis confirmed that the proband has a rare para-Bombay phenotype. Direct sequencing revealed that he was a B.01/O.01.02 heterozygote for the ABO gene, and had heterozygous deletion for the 768 and 881-882 sites of the FUT1 gene. Further haploid analysis showed that the c.881_882delTT deletion has occurred in one haploid while c.768delC was present in the other haploid. The proband was therefore determined as a FUT1*01N.13/01N.20 heterozygote, which have resulted in frameshift in polypeptide chain p.Phe294Cysfs*40 and p.Val257Phefs*23, respectively.
CONCLUSION
A rare bi-allelic heterozygous deletion of para-Bombay phenotype has been identified in a blood donor. The c.881_882delTT and c.768delC deletions may decrease the activity of α-1,2-fucosyltransferase.

Objective:To understand the thyroid function of the physical examination population in Tangshan area, and analyze the effects of thyroid function on blood lipids, fasting blood glucose (FPG), and serum 25 hydroxyvitamin D [25(OH)D].Methods:A population from the Tangshan area who underwent physical examinations at the Kailuan General Hospital from June 2020 to June 2021 was selected as the study subjects and the levels of their thyroid serological indicators [thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (TT3), and thyroid hormone (TT4)] were tested. According to thyroid function, they were divided into normal group, hyperthyroidism group, hypothyroidism group, subclinical hyperthyroidism group, and subclinical hypothyroidism group. We compared the blood lipid indicators [triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)], FPG, and 25(OH)D levels in different subgroups, and the Pearson correlation analysis was used to investigate the correlation between TSH levels and blood lipids, FPG, and 25(OH)D levels.Results:In this study, 2 884 subjects were selected from the physical examination population in Tangshan area. The proportion of people with abnormal thyroid function was 12.03%(347/2 884), among which the proportion of subclinical thyroid function abnormal population in the total thyroid function abnormal population was 80.69%(280/347). As men age, the proportion of thyroid dysfunction in the age groups of 21-<30 years old, 30-<40 years old, 40-<50 years old, and ≥50 years old was 5.06%(4/79), 7.52%(33/439), 8.91%(53/595), and 9.95%(66/663), respectively. The proportion of thyroid dysfunction in the above age group of women was 14.02%(15/107), 15.06%(61/405), 15.47%(67/433), and 29.45%(48/163). The serum TG, TC, LDL-C, and 25(OH)D levels in the hyperthyroidism group were lower than those in the normal group, while HDL-C and FPG levels were higher than those in the normal group, with statistically significant differences (all P<0.05). The serum TG and TC in the hypothyroidism group were higher than those in the normal group, while FPG and 25(OH)D were lower than those in the normal group, with statistically significant differences (all P<0.05). TSH levels were positively correlated with TC and LDL-C, while negatively correlated with FPG and 25(OH)D (all P<0.05). Conclusions:Subclinical thyroid dysfunction is the main cause of thyroid dysfunction in the Tangshan area, and TSH levels are correlated with blood lipids, fasting blood glucose, and serum 25(OH)D levels.

Objective:
To investigate the difference of clinical characteristics of recurrent spontaneous abortion (RSA) in patients with losses after spontaneous gestation and after in vitro fertilization and embryo transfer ( IVFET) .
Methods :
237 patients diagnosed with RSA were divided into spontaneous gestation group ( n = 185) and IVF group (n = 52) according to their previous modes of fertilization.The clinical characteristics of the two groups were analyzed.
Results:
Compared with the spontaneous gestation group,the age of the first pregnancy and the age at the time of RSA in the IVF group were statistically greater than those in the natural pregnancy group ( P < 0. 05 ) .The number of biochemical pregnancies in IVF group was statistically higher than that in spontaneous gestation group,and the number of spontaneous abortions in IVF group was statistically lower than that in spontaneous gestation group (P<0. 001) .The proportion of patients with irregular menstruation in IVF group was statistically higher than that in spontaneous gestation group ( P < 0. 05 ) . The serum activated partial prothrombin time (APTT) ,R , K,high density lipoprotein cholesterol (HDL-C) ,thyrotropin (TSH) and homocysteine ( HCY) in IVF group were statistically lower than those in spontaneous gestation group,and the Angel,Ma,low density lipoprotein cholesterol (LDL-C) and body mass index (BMI) in IVF group were statistically higher than those in spontaneous gestation group (P<0. 05) .In the comparison of etiological composition between the two groups,the proportion of anatomical factors in IVF group was statistically higher than that in spontaneous gestation group (P < 0. 05) .
Conclusion
The abortion risk factors in RSA patients after IVF-ET is more serious than that in RSA patients after natural pregnancy.It is suggested to further improve and implement the pre-pregnancy examination and education of infertile patients during IVF-ET treatment,so as to reduce the risk of RSA and obtain a better pregnancy outcome.

Objective :
To analyze the metabolism of blood glucose,blood lipid and insulin in patients with recur- rent pregnancy loss (RPL) ,and to compare the predictive efficacy of triglyceride glycemic index (TyG) ,triglycer- ide glycemic body mass index (TyG-BMI) and homeostatic model assessment of insulin resistance( HOMA-IR) for RPL.
Methods :
A total of 573 patients with RPL were selected as the RPL group,and 652 women who received as- sisted reproductive technology for male infertility were selected as the control group.The general data of the two groups were retrospectively analyzed.The levels of body mass index(BMI) ,fasting blood glucose (FPG) ,fasting triglyceride (FTG) ,fasting insulin ( FINS) ,TyG index,TyG-BMI index and HOMA-IR were compared between the two groups.Spearman correlation analysis was used to verify the correlation between TyG index,TyG-BMI in- dex and HOMA-IR. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of TyG index,TyG-BMI index and HOMA-IR for RPL occurrence,and the optimal predictive cut-off point was calculated.
Results :
The BMI,FPG,FTG,TyG index,TyG-BMI index and HOMA-IR in the RPL group were significantly higher than those in the control group (P<0. 05) .TyG index and TyG-BMI index were positively correlated with HOMA-IR , and the correlation coefficients were 0. 442 and 0. 505,respectively (P<0. 001) . ROC curve a- nalysis showed that the area under the curve of TyG-BMI index predicting RPL was 0. 579 (95% CI : 0. 551 - 0. 607,P<0. 001) ,which was greater than that of TyG index of 0. 557 (95% CI : 0. 529-0. 585,P<0. 001) and HOMA-IR of 0. 535 (95% CI : 0. 507 -0. 563,P <0. 05) ,among which the difference between TyG-BMI index and HOMA-IR index area under the curve was statistically significant (P <0. 05 ) .The optimal cut-off points of TyG-BMI index ,TyG index and HOMA-IR for predicting RPL were 172. 3 ( sensitivity 75. 7% ,specificity 37. 06% ) ,8. 32 ( sensitivity 59. 44% , specificity 51. 61% ) and 3. 58 ( sensitivity 25. 87% , specificity 81. 62% ) ,respectively.
Conclusion
The incidence of overweight,abnormal blood glucose,lipid and insulin me- tabolism in RPL patients is higher than that in normal women.TyG index and TyG-BMI index can be used as indi- cators of insulin metabolic status in RPL population besides HOMA-IR , and TyG-BMI index has a higher efficacy in predicting the occurrence of RPL compared to HOMA-IR.
