Objective To explore the relationship between MTHFR gene polymorphism and ~diabetic cardiovascular disease. Methods The MTHFR C677T and MTHFR A1298C gene polymorphisms were detectd by PCR-RFLP to compare MTHFR C677T and MTHFR A1298C genotype distribution and allele frequencies among three groups. Enrolled were 84 healthy individuals (NC) and 158 T2DM subjects who were classified into two groups, i.e. non-diabetes complications (NDC) and ~diabetic cardiovascular disease (DC). Results Patients with diabetic cardiovascular disease had higher frequencies of MTHFR C677T mutation genotype and T allele than control and non-diabetes complications subjects, and had lower folate levels (P<0.001). There were no significant differences in MTHFR A1298C genotype distribution and allele frequencies among three groups (P>0.05). A logistic regression analysis demonstrated that MTHFR C677T and age were the independent predictors of DC. Conclution There is a strong correlation between the polymorphism of MTHFR C677T and diabetic cardiovascular disease.

Objective To investigate the expression of radiation-induced IER5 protein and screen its potential interaction proteins that may participate in DNA repair process.Methods HeLa cells were irradiated with 4 Gy ionizing radiation.IER5 protein expression in whole cell lysate and in nuclear fraction were detected by Western blot at different timepoints after irradiation.3 × Flag-IER5 pCMV plasmid was constrcuted and the Flag tagged-IER5 expression was verified by Western blot.293T cells were transfected with 3 × Flag-IER5 pCMV plasmid.After irradiation the cells were collected and proteins were extracted.The IER5 interaction proteins were purified using immunoprecipitation and separated by 12％ SDS-polyacrylamide gel electrophoresis.Then the binding proteins were cut from the gel and analyzed by Mass spectrometry.Results The expression of IER5 protein began to increase 4 hour post-irradiation and its peak level was observed at 12 hour post-irradiation,and it lasted until 48 hour after irradiation.The expression level of IER5 protein in whole cell lysate and nuclear fraction were both increased.With the mass spectrometry analysis,a total of 347 proteins and 256 proteins were identified in irradiated and nonirradiated groups,respectively.Fourty one differential proteins were obtained,where 10 proteins were associated with DNA metabolic process and DNA rapair in the irradiated group and the poly(ADP-ribose) polymerase 1 (PARP1) protein was further confirmed by Western blot.Conclusions IER5 protein is an DNA damage related protein,and it may participate in DNA repair process.

Objective To seak a available way of evaluating morphology of filtering blebs after trabeculectomy is very important for forecasting the successful rate of surgery.At the present time,filtering blebs were commonly evaluated by using the slim lamp microscope,but it did not to exactly reflect the filtering passage.This study aimed to evaluate the morphology of filtering blebs after trabeculectomy with anterior segment optical coherence tomography (AS-OCT).MethodsThis was a prospective study.Sixty-nine eyes of 53 patients who had previously undergone trabeculectomy were selected in this study,including 25 eyes with open-angle glaucoma,38 eyes with close-angle glaucoma and 6 eyes with secondary glaucoma.These filtering blebs were classified into functional type (typeⅠandⅡ) and nonfunction type (type Ⅲ and Ⅳ) under the slit lamp microscope based on the van Buskirk grading scales.Intra-bleb morphology and structure were characterized as diffuse-like,cystic-like,encapsulating-like and flatten-like by AS-OCT in reference to the Leung method.The consistency between the two methods was evaluated by the Chi-Square test.Written informed consent was obtained from all the patients before surgery.ResultsThe average follow-up time was 10.78±11.0 months.All the patients finished the examination during the follow-up duration.The average intraocular pressure was(14.9±4.5)mmHg during the observation period.There were 38/69 (55.1%) functioning blebs and 31/69 (44.9%) non-function blebs under the slim lamp microscope.AS-OCT imaging showed diffuse-like blebs in 26 eyes (15.9%),cystic-like blebs in 11 eyes (27.5%),encapsulating-like blebs in 19 eyes (18.8%) and flatten-like in 13 eyes with the intraocular pressure of(13.16±3.77)mmHg,(15.36±2.92)mmHg,(15.77±5.07)mmHg and (16.62±5.33)mmHg,respectively,showing a significant difference among them (F=3.32,P＜0.05).These patterns of different OCT presented a good consistency with the clinical outcome (χ~2=0.03,P=0.86).ConclusionAS-OCT allows the observation of filtering blebs after glaucoma surgery.It is probably to visualize the internal structure of filtering bleb and deep sclerectomy.Functional and dysfunctional filtering blebs delivery gives different OCT patterns.This could be a new way to assess the postoperative healing process.

Objective To assess the risk factors for the occurrence of hypokalemia in patients with hepatic cancer after transcatheter arterial chemoembolizaion (TACE) therapy,and to discuss the corresponding nursing countermeasures.Methods The clinical data of 214 patients with hepatic cancer,who received TACE during the period from August 2014 to February 2015,were retrospectively analyzed.The risk factors causing hypokalemia were analyzed.Results Among the 214 patients,post-TACE hypokalemia occurred in 23 (10.7％).The main risk factors that could cause hypokalemia included anorexia,hydration,vomiting,ascites drainage,sweating.After actively symptomatic treatment,the serum potassium level returned to normal in 22 patients.One patient developed hepatic encephalopathy coma complicated by hepatorenal syndrome,the patient's family members gave up treatment and,according to family members' will the patient left hospital.Conclusion anorexia,vomiting,hydration,ascites drainage,sweating are the risk factors that can cause hypokalemia in patients with hepatic cancer after TACE therapy.The use of low potassium risk scale is helpful for the formulation of nursing countermeasures.

OBJECTIVE: To investigate the feasibility of the treatment of otosclerosis using laser stapedotomy with mini incision in the external auditory meatus. METHOD: Thirteen patients(15 ears) with otosclerosis evidence on clinic history. They were all operated using the laser assisted stapedotomy by mini incision in external auditory meatus because of the wide straight canal. Laser resection the tendo musculistapedius and anterior and postrior arch, breaking the articulatioincudostapedia, removing the stapes superstructure, making a hole of 6mm diameter in the rear of stapes footplate by laser drilling, implanting the corresponding length Piston artificial ossicle. RESULT: All the surgeries were successful and the operation time was about one hour. There was only one patient manifested vertigo and nausea after the operation. But the symptoms improved three days later after the expectant treatment. All the incisions were healed in the externals. There was significant difference between the preoperative and postoperative PTA. The air conduct improved in every frequent and the bone conduct improved in 1 kHz, 2 kHz and 4 kHz. CONCLUSION Laser assisted stapedotomy by mini incision in the external auditory meatus in patients having wide straight canal with otosclerosis can shorten the operation time, minimize the tissue damage, fasten the healing of the incision and reduce the complications postoperatively.

BACKGROUND:Bone marrow mesenchymal stem cel transplantation is considered as a promising therapy for spinal cord injury. How to more effectively promote the survival of bone marrow mesenchymal stem cel s in the area of spinal cord injury and to accelerate the recovery of motor function after spinal cord injury is a current study focus. Previous studies have found that low-frequency electromagnetic fields can promote bone marrow mesenchymal stem cel proliferation and differentiation, but whether the low-frequency electromagnetic fields can be applied to bone marrow mesenchymal stem cel transplantation for treatment of spinal cord injury requires further studies. OBJECTIVE:To discuss the effects of low-frequency electromagnetic fields on motor function of spinal cord injury rats after transplantation of bone mesenchymal stem cel s. METHODS:Sixty-four rat models of incomplete spinal cord injury at T 10 were established by compression method and then randomized into control group, transplantation group (bone mesenchymal stem cel transplantation), electromagnetic field group and combination group (electromagnetic field+bone mesenchymal stem cel transplantation). After successful modeling, bone mesenchymal stem cel s labeled with 5-bromo-2'-deoxyuridine were injected into the original injured site in the transplantation group and combination group, which were isolated and purified with the fast adherence method;while alpha-minimum essential medium was injected into the electromagnetic field group and control group for instead. At 24 hours post-operation, the electromagnetic field group and combination group were explored to low-frequency electromagnetic fields (frequency 50 Hz, magnetic indaction intensity 5 mT) for 60 minutes per day. RESULTS AND CONCLUSION:After cel transplantation for 21 days, the Basso, Beattie, and Bresnahan scores in the combination group was higher than the other groups (P<0.05). 5-Bromo-2'-deoxyuridine positive cel s grew wel , and integrated into the normal spine;syringomyelia was reduced, and the number of spinal neural cel s was increased in the combination group. In addition, glial fibril ary acidic protein expression was decreased in the combination group, while matrix metal oproteinase 2 expression was increased. It indicates that low-frequency electromagnetic fields could promote recovery of motor function in the spinal cord injury rats transplanted with bone mesenchymal stem cel s, which could be associated that low-frequency electromagnetic fields facilitate the survival of transplanted bone mesenchymal stem cel s, up-regulate the expression of matrix metal oproteinase 2, and reduce glial scar formation in the spinal cord injured site.

Objective:To evaluate the performance of RapidArc technique on cervical cancer patients with various filling status of the bladder. Methods: Conventional fixed field intensity modulation radiated therapy (IMRT) is used as the benchmark. In 10 fe-males suffering from cervical cancer, two CT scans were performed for treatment planning:one with an empty bladder and the other with filled bladder. The prescribed dose was 50 Gy. The images of that with an evacuated bladder and that with filled bladder were planned in the dual-arc RapidArc and the 7-field IMRT, respectively. The implementor of the plan was the Varian TrueBeam linear ac-celerator. Dose-volume histogram was used to evaluate the data from each plan. Results:When the bladder was filled, IMRT and Rapi-dArc homogeneity were 1.05 and 1.04 (P>0.05), respectively. When the bladder was emptied, the homogeneity was 1.04 for both plans (P>0.05). With or without bladder filling, the conformity index was 0.71 and 0.73 for IMRT and RapidArc (P>0.05), respectively. The effect of V30 and V40 (volume for receiving doses of 30 and 40 Gy) on the intestine and the bladder was more favorable in a full than in an empty bladder. No significant difference between the two plans was observed. IMRT exhibited improved V30 on the rectum and on the bladder. RapidArc was much better in terms of monitor unit (MU) and deliver time. Conclusion:No significant differences in the homogeneity and conformity index between dual-arc RapidArc and 7-field IMRT were observed. Filled bladder is better than empty bladder in intestine and bladder protection in both RapidArc and IMRT. IMRT is better on V30 of the rectum and the bladder, whereas RapidArc improved MU and deliver time.
