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 explore the genetic etiology for a pedigree affected with progressive familial intrahepatic cholestasis (PFIC). METHODS: Target sequence capture and next generation sequencing (NGS) were applied for the proband. PCR and Sanger sequencing were used to verify the suspected mutation in his sister with similar symptoms and his parents. RESULTS: The proband and his sister manifested after birth with symptoms including jaundice, pruritus and developmental retardation. NGS has identified compound heterozygous mutations of ABCB11 gene, which encodes bile salt export pump protein (BSEP), namely c.2494C>T (p.Arg832Cys) and c.3223C>T (p.Gln1075*), in the proband, which were inherited from his father and mother respectively. His sister carried the same compound mutations. CONCLUSION Based on the phenotype and genetic testing, the patients were diagnosed as PFIC2 caused by mutation of the ABCB11 gene. The c.3223C>T is a novel nonsense mutation which may cause premature termination of translation. Above results have enriched the spectrum of ABCB11 mutations and provided new evidence for the molecular basis of PFIC, which also facilitated genetic counseling for this pedigree.

Objective: To figure out the clinical application value of indocyanine green (ICG) lymphangiography in supermicrosurgical lymphaticovenular anastomosis. Methods: A total of 6 supermicrosurgical lymphaticovenular anastomosis with intraoperative ICG lymphangiography were performed during April 2015 to May 2017 and were analyzed retrospectively. All the cases are female (range from 30 to 54 years old, median of 46.5 years old), including 3 cases for prevention and 3 cases for treatment of lymphedema. Results: A total 6 supermicrosurgical lymphaticovenular anastomosis were performed with intraoperative ICG lymphangiography to make sure the influx of lymph fluid to the vein. During the median of 23 months follow-up (range from 7 to 32 months), the 3 preventive cases did not show upper limb lymphedema and the 3 theraputic cases were relieved at different levels. Conclusions Intraoperative ICG lymphangiography can provide real-time information to locate suitable lymph vessels and ascertain the anastomotic patency in supermicrosurgical lymphaticovenular anastomosis, thus improve the operation effectiveness.

Microsurgery techniques have allowed the development of many new therapeutic methods in plastic surgery, but are difficult to master without hard training. It is very important to set up a standardized microsurgery curriculum and training system for broadening surgical skills training and investigating the plastic surgery specialist training strategy. In our experiences, a series of training models are needed, like non-animal models, non- living animal models, live animal models and so on. This paper shows the training strategy for the primary stage of microsurgery training, non-animal model and non-living animal model training.
