Objective: To prepare the monoclonal antibody against ankyrin repeat domain 22（ANKRD22）and to investigate its expression in colorectal cancer tissues. Methods : The recombinant human ANKRD22 was expressed through E. coli and pET-42a and then used to immunize Balb/c mice after purification. Anti-human ANKRD22 specific monoclonal antibodies were selected by Western blotting with 293T cell lysate highly expressing ANKRD22 as antigen. The expression of ANKRD22 in the tissue microarrays of 112 patients with colorectal cancer was detected by immunohistochemical staining. Results : Four specific monoclonal antibodies against human ANKRD22 were screened out of 93 hybridoma cells,which reacted well with natural human ANKRD22. ANKRD22 was mainly distributed in the cytoplasm of colorectal cancer cells. In 112 cases of colorectal cancer,94 cases were detected positive for ANKRD22 expression,with the positive rate of 83.93%. The expression of ANKRD22 was statistically correlated with the expression of p53 and β-catenin（P<0.05）,but not with age,sex,location of tumors,AJCC stage,Dukes stage,degree of differentiation,lymph node metastasis and mismatch repair gene expression（P>0.05）. Conclusion The expression level of ANKRD22 was high in colorectal cancer. ANKRD22 might be involved in the carcinogenesis of colorectal epithelium and be a potential diagnostic marker.

Objective:To explore the risk factors of diabetic nephropathy(DN).Methods:From January 2016 to September 2019, the clinical data of 403 patients with type 2 diabetes in the Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were analyzed retrospectively.Excluding other factors, they were divided into DM group (315 cases) and DN group(88 cases) according to whether or not they were complicated with DN.The age, course of disease, complications, monocyte to high-density lipoprotein cholesterol ratio(MHR) and other test data were included in the logistic regression model to analyze the independent risk factors of DN.Results:There were statistically significant differences in the course of ≥10 years[95 cases(30.16%) vs.37 cases(42.05%)], complicated with hypertension[141 cases(44.76%) vs.58 cases(65.91%)], insulin application[94 cases(29.84%) vs.39 cases(44.32%)], ACEI/ARB application[132 cases(41.90%) vs.62 cases(70.45%)], FBG[(7.38±2.45)mmol/L vs.(8.26±2.06)mmol/L], HbA1c≥7%[91 cases(28.89%) vs.36 cases(40.91%)], MHR[(10.30±4.38) vs.(17.10±7.18)] and HDL-C[(0.58±0.16)mmol/L vs.(0.52±0.17)mmol/L] between the two groups( t=4.41, 13.31, 6.52, 22.46, 3.08, 4.60, 11.02, 2.65, all P<0.05). Multivariate logistic regression analysis showed that hypertension( OR=2.06, 95% CI=1.36-2.76), HbA1c≥7%( OR=1.32, 95% CI=1.04-1.60), MHR≥11.78( OR=1.65, 95% CI=1.03-2.67) were independent risk factors for DN. Conclusion:Hypertension, HbA1c ≥7%, MHR ≥11.78 are independently correlated with DN, which provide a basis for clinical prognosis.

Objective:To explore the relationship between sex hormone binding globulin and glycolipid metabolism in patients with obese polycystic ovary syndrome.Methods:From April 2016 to April 2019, 114 patients with obese polycystic ovary syndrome in the Integrated Chinese and Western Medicine Hospital of Wenzhou were selected and divided into two groups according to the level of sex hormone binding globulin, including 66 cases in the low level group and 48 cases in the normal group.The blood glucose, blood lipid and sex hormone levels of the two groups were measured and the results were analyzed.Results:The levels of TC, TG, LDL-C and ApoB in the low level group[(2.32±0.97)mmol/L, (6.45±1.25)mmol/L, (3.57±1.01)mmol/L, (0.93±0.32)g/L] were significantly higher than those in the normal group[(1.87±0.89)mmol/L, (4.88±0.94)mmol/L, (3.12±0.88)mmol/L, (0.76±0.17)g/L]( t=2.477-7.322, all P<0.05). The level of ApoA in the low level group[(1.22±0.34)g/L] was significantly lower than that in the normal group[(1.58±0.47)g/L]( t=-4.748, P<0.05), while there was no statistically significant difference in HDL-C between the two groups[(1.45±0.31)mmol/L vs.(1.43±0.56)mmol/L, t=0.244, P>0.05]. The levels of FPG, HbA1C and FINS in the low level group[(5.53±1.45)mmol/L, (6.42±0.79)% and (18.71±5.46)mU/L] were significantly higher than those in the normal group[(5.09±0.76)mmol/L, (6.01±0.92)% and (15.49±4.98)mU/L]( t=2.136-3.225, all P<0.05), while there was no statistically significant difference in 2hPG between the two groups[(8.79±1.56)mmol/L vs.(8.32±1.84)mmol/L]( t=1.472, P>0.05). The incidence of insulin resistance in the low level group[54.55%(36/66)] was significantly higher than that in the normal group[35.42%(17/48)](χ 2=4.088, P<0.05). The level of T in the low level group[(61.45±21.44)ng/mL] was significantly higher than that in the normal group[(50.39±22.31)ng/mL]( t=2.673, P<0.05), while there were no statistically significant differences in FSH, LH, E 2 and PRL between the two groups( t=0.427-1.714, all P>0.05). Conclusion:The patients with low levels of sex hormone binding globulin are more likely to suffer from hyperglycemia and hyperlipidemia, and low levels of sex hormone binding globulin may be a risk factor for obese polycystic ovary syndrome.

Objective:To investigate the efficacy and safety of ixazomib-based therapy for multiple myeloma.Methods:The data of 32 patients with multiple myeloma treated with isazomib-based regimen in the Affiliated Hospital of Jining Medical University from December 2020 to December 2021 were retrospectively analyzed. Among 32 patients, 17 cases were relapsed/refractory, and the remaining 15 cases had initial treatment. The treatment regimens included ID (isazomib + dexamethasone), IRD (isazomib + lenalidomide + dexamethasone) and ICD (isazomib + cyclophosphamide + dexamethasone). The short-term curative effect and adverse reactions of relapsed/refractory patients and patients at initial onset were analyzed.Results:The overall response rate (ORR) of relapsed/refractory patients was 52.9% (9/17), of which 6 cases achieved complete remission (CR), 2 cases achieved very good partial remission (VGPR) and 1 case achieved partial remission (PR). The ORR of refractory patients receiving bortezomib therapy was 40.0% (4/10). The ORR of patients at initial onset who could be evaluated the curative effect was 100.0% (14/14), including 9 cases of CR, 2 cases of VGPR and 3 cases of PR. After treatment, 2 patients (6.2%) had grade Ⅲ-Ⅳ adverse events (1 case of herpes zoster and 1 case of thrombocytopenia), and none of the patients had grade Ⅲ-Ⅳ peripheral neuropathy.Conclusion:Isazomib is effective and safe in the treatment of initially treated and relapsed/refractory multiple myeloma.

OBJECTIVE: To carry out prenatal diagnosis for a fetus with normal ultrasonographic finding at 20 weeks' gestation but a copy number variant(CNV) of 13q indicated by non-invasive prenatal test (NIPT). METHODS: Karyotyping analysis and chromosomal CNV assay were carried out on the amniotic fluid sample. Parental peripheral blood sample was collected for chromosomal analysis. Detailed fetal ultrasound scan was carried out to rule out structural abnormalities of the fetus. RESULTS: The fetus was detected with a heterozygous 10.14 Mb deletion at 13q21.1q21.32, which has originated from the phenotypically normal mother. No apparent karyotypic abnormality was detected in the fetus and its parents. No ultrasonic abnormality was found in the fetus. CONCLUSION Both the fetus and its mother have carried a heterozygous 10.14 Mb deletion at 13q21.1q21.32 and presented normal phenotypes.Combined with literature review, the segmental deletion was judged to be a benign variant.

OBJECTIVE: To explore the genetic etiology of three pedigrees with a gestational history of fetal renal anomalies. METHODS: Peripheral venous blood or skin samples were derived from the probands of the three pedigrees. Copy number variation sequencing (CNV-seq) was applied to detect alterations of genome CNVs. RESULTS: The patient from pedigree 1 and the fetuses from pedigrees 2 and 3 all carried a heterozygous 17q12 deletion, with the size ranging from 1.4 Mb to 1.48 Mb encompassing the HNF1B gene. CONCLUSION The diagnosis of 17q12 microdeletion may be difficult during fetal period for its variable phenotypes. Alterations of chromosomal copy numbers need to be excluded in such patients.

OBJECTIVE: To carry out genetic analysis for a family with a fetus manifesting bilateral polycystic renal dysplasia and oligohydramnios at 16 gestational week and a previous history for fetal renal anomaly. METHODS: Ultrasound scan was carried out to detect the morphological changes. Following genetic counselling, the parents had decided to terminate the pregnancy. Fetal kidneys were subjected to histological examination. Target capture and next generation sequencing (NGS) was applied to the abortus to detect potential variants. The results were verified by Sanger sequencing. RESULTS: Histological examination of fetal kidneys revealed cystic changes without cortex, medulla or normal renal structure. NGS has identified a heterozygous c.100+1G>A variant and deletion of exon 3 of the INVS gene, which were respectively inherited from the mother and father. CONCLUSION Through NGS and Sanger sequencing, the fetus was diagnosed with type II nephronophthisis (NPHP2). Above result can provide guidance for further pregnancy and enforce understanding of clinical features and genetic etiologies for NPHP.

Objective: The phenotype and genetics of three patients with autosomal recessive polycystic kidney disease (ARPKD) at childhood, teenage and advanced age were analyzed. Methods: Next generation sequencing (NGS) was applied to all the probands. PCR and Sanger sequencing were used to verify the suspicious gene variants screened by NGS in the probands and their family members, and one of the family got prenatal diagnosis. Results: Through NGS, PCR and Sanger sequencing, the 5-yr proband in pedigree 1 was shown to carry compound heterozygous variants of c. 5935G>A(p.G1979R) and c. 5428G>T(p.E1810X) of PKHD1, originated from his parents; In pedigree 2, the 17-ys proband was detected with c. 5512T>C(p.Y1838H) and c. 5935G>A(p.G1979R) variants of PKHD1 orginated from her parents, and her mother also got prenatal diagnosis during the second trimester; In pedigree 3, the 70-ys female proband was found with variants c. 11314C>T (p.R3772X) and c. 3860T>G (p.V1287G) of PKHD1. Conclusion The three pedigrees were diagnosed as ARPKD caused by PKHD1 variants. Five types of variants were detected, c. 5935G>A and c. 11314C>T were the known pathogenic variants, while c. 5512T>C, c. 5428G>T and c. 3860T>G were not reported previously. Considering the complexity of the genetics and phenotypes of the cystic renal diseases, genetic diagnosis is crucial to give accurate etiological diagnosis, which may benefit the clinic management.
