Objective:To investigate the role of TCF7L2 gene polymorphism and related mechanisms in postmenopausal women with type 2 diabetes mellitus (T2DM) who are at high risk for osteoporosis (OP) .Methods:148 postmenopausal women with T2DM from Jan. 2019 to Jun. 2020 were selected as study subjects. Among them, 86 patients combined with OP (T2DM+OP group) and 62 patients without OP (T2DM group) were included, and 100 healthy postmenopausal women who underwent physical examination in our hospital during the same period were included as the control group. Fasting venous blood was extracted to detect clinical and bone metabolism indicators. Two SNP sites of TCF7L2, rs7901695 (T>C) and rs290487 (C>T) , were genotyped by capillary electrophoresis and section analysis (SNaPshot) . The relative mRNA expression of TCF7L2 gene was determined by quantitative real-time fluorescence quantitative PCR assay. To investigate the effects of overexpression and silencing of TCF7L2 on proliferation of rat osteoblasts, lentiviral vectors were constructed.Results:For rs7901695, TT, TC and CC genotypes in T2DM+OP group, T2DM group and control group were significantly different ( χ2=12.545, P=0.014) , and the frequency distribution of T and C alleles was significantly different among the three groups ( χ2=17.089, P<0.001) . For RS290487, CC, CT and TT genotypes of T2DM+OP group, T2DM group and control group were significantly different ( χ2=10.500, P=0.033) , and the frequency distribution of C and T alleles was significantly different among the three groups ( χ2=14.665, P=0.001) . For rs7901695, FPG and TG levels in T2DM+OP patients with CC+TC genotype were significantly higher than those with wild-type TT genotype (FPG: t=2.559, P=0.014; TG: t=2.034, P=0.036) , while serum calcium and 25OHD3 levels were significantly lower than those with Wild-type TT genotype (calcium: t=3.889, P<0.001; 25OHD: t=4.112, P<0.001) . For rs290487 site, serum calcium, BGP and 25OHD3 levels in T2DM+OP patients with TT+CT genotype were significantly lower than those with wild-type CC genotype, and the difference was statistically significant (calcium: t=3.751, P<0.001; BGP: 2.731, P=0.007; 25OHD3: t=3.225, P=0.002) . The relative mRNA expression level of TCF7L2 gene in T2DM+OP patients was significantly lower than that in T2DM group and the control group ( F=5.735, P<0.05) . With the increase of Allele C at rs7901695, the relative mRNA expression level of TCF7L2 gene decreased gradually ( F=5.723, P<0.05) . In addition, the proliferation rate of rat osteoblasts overexpressed by TCF7L2 was significantly increased, while the proliferation level of TCF7L2 silenced osteoblasts was significantly decreased ( F=7.846, P<0.05) . Conclusion:In postmenopausal WOMEN with T2DM, the variation of TCF7L2 gene will lead to the decrease of gene expression level, and the suppression of osteoblasts proliferation, thus participate in the pathogenesis of OP.

ObjectiveTo explore the clinical value of ultrasonography in the detection of median nerve in diabetic peripheral neuropathy (DPN).MethodsMedian nerve was detected in 70 healthy adults (control group) and 43 patients with type 2 diabetes mellitus (diabetes mellitus group) by color Doppler ultrasonography.The type 2 diabetes mellitus patients were divided into two groups according to the duration of the disease:< 10 years group (26 cases) and ≥ 10 years group( 17 cases).And they were divided into two groups according to the random plasma glucose (RPG):RPG < 15 mmol/L group(28 cases) and RPG≥ 15mmol/L group ( 15 cases).The nerve cross section area (CSA) was taken at the level of the pisiform.Results The median nerve in diabetes mellitus group had decreased echogenicity and increased color in it.The CSA of the median nerve in diabetes mellitus group was significantly higher than that in control group [ ( 10.3 ± 2.1 )mm2 vs. (8.3:± 1.7) mm2 ] (P < 0.01 ).The C SA of the median nerve in ≥ 10 years group was significantly higher than that in <10 years group [ ( 12.3 ± 2.0) mm2 vs.( 10.2 ± 2.6) mm2] (P < 0.01 ).The CSA of the median nerve in RPG ≥ 15 mmol/L group was significantly higher than that in RPG < 15 mmol/L group [ ( 11.7 ± 1.8) mm2 vs.(9.6 ± 2.7 ) mm2 ] (P < 0.01 ).ConclusionColor Doppler ultrasonography examination may reveal morphology of median nerve and is useful for the diagnosis of DPN.

Objective: To investigate the enhancive effect of TNF-α on transfection efficiency of adenovi-rus in mononuclear cells of mouse and the enhancive capability of protection of bone marrow by MDR1. Meth-ods: Before the mononuclear cells of mouse were infected by recombinant adenovirus encoding human MDR1 gene, they had been pretreated by TNF-α. Transfection efficiency of adenovirus was monitored by fluo-rescence microscopy, immunohistochemistry and flow cytometry (FCM). mRNA and protein levels of MDR1 in the mononuclear cells of mouse were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot before and after treatment of TNF-α. Results: After treatment of TNF-α, tansfection rates of adenovirus were obviously increased in the treated group (26.26%) compared with the untreated group (11.96%). mRNA levels and protein levels of MDR1 were obviously increased in the treated group compared with the untreated group. Conclusion: TNF-α could enhance transfection efficiency of adenovirus in mononu-clear cells of mouse and enhance capability of protection of bone marrow by MDR1.

Objective To study effects of exectin hydrochloride and intensity modulated radiotherapy in treatment of patients with advanced lung cancer and its effect on levels of carcinoembryonic antigen (CEA), neuron-specific enolase (NSE) and serum glycoprotein antigen 199 (CA199). Methods 88 patients with advanced lung cancer were selected from June 2014 to June 2016 in our hospital were selected and randomly divided into observation group and control group, 44 cases in each group.In the control group, the patients were treated with IMRT, and the observation group was treated with exectin hydrochloride on the basis of control group.The clinical efficacy and adverse reaction were compared between the two groups.The levels of CEA, NSE and CA199 before and after treatment were analyzed.Results After treatment, the total effective rate in the observation group 84.09% was significantly higher than the control group 52.27%, the difference was statistically significant (P<0.05).Before treatment, the levels of CEA, NSE and CA199 of the two groups had no significantly different, after treatment, the levels of CEA, NSE and CA199 of the two groups were significantly lower than before treatment, the difference was statistically significant (P<0.05).CEA, NSE, CA199 levels in the observation group were significantly lower than the control group, the difference was statistically significant (P<0.05).There was no significant difference in adverse reaction rate of I-II, III-IV liver function, gastrointestinal reaction, bone marrow suppression and acute radiation pneumonitis in observation group and control group.Conclusion Ectectin hydrochloride combined with intensity modulated radiotherapy can effectively reduce the levels of CEA, NSE and CA199 in patients with advanced lung cancer, and the clinical efficacy is good, and will not increase the adverse reaction rate.

AIM: To investigate the chemotaxis mechanisms of polymerphonuclear leukocytes (PMNs) under the stimulation of LPS and its regulation by polydatin (PD). METHODS: Chemotactic chamber assay was used to investigate the regulatory role of formyl peptide receptor like-1 (FPRL1) in the chemotaxis of PMNs in response to LPS and PD. RESULTS: LPS increased the secretion of PMN chemotactic factor and up-regulated the function of formyl peptide receptor like-1. PD did not obviously affect the chemotactic factor secretion in normal PMN and the function of formyl peptide receptor like-1, but it significantly reduced the rise of chemotactic factor excretion in PMNs caused by LPS stimulation and PMNs transfected with formyl peptide receptor like-1. CONCLUSION: FPRL1 may mediate LPS-induced PMN chemotaxis, and PD regulates PMN chemotaxis by down-regulating the secretion of chemokine and the function of FPRL1 and may play a crucial role in the treatment of inflammation.
