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.

BACKGROUND: Major psychological problems in patients with carcinoma of large intestine(CLI) were depression and anxiety. Are these bad moods correlated with the pathological stages, the pathological classification and the clinical manifestation of CLI?OBJECTIVE: This study was designed to investigate the relationship between the depression and anxiety state and the clinical manifestations in CLI patients.DESIGN: A comparative observation on patients was conducted in this study.SETTING: This study was conducted at the Department of General Surgery, General Hospital of Shenyang Military Area Command(MAC) of Chinese PLA and the Department of General Surgery, the 307 Hospital of the Chinese PLA. PARTICIPANTS: This study was conducted in the General Surgery Department of the General Hospital of Shenyang Military Area Command of Chinese PLA from February 2002 to February 2003. Totally 79 inpatients and outpatients were diagno sed as CLI by pathological examination. Their informed consents were obtained. Among them, 68 were accordant with the inclusion criteria, 51 males and 17 females; 21 with an age ≥55 years and 47 with an age ＜ 55 years; 39 with an average course of disease≥10 weeks and 29 with an average course of disease ＜10 weeks; 49 in Dukes A-C stages of CLI and 19 in Dukes D stage; 13 with a cancer of anal canal, 55 with a nonanal-canal cancer; 42 with a squamous cell carcinoma and 26 with a nonsquamous carcinoma; 40 with a serum level of carcinoembryonic antigen(CEA) ≥30 μg/L and 28 with it ＜30μg/L; 44 with a serum level of interleukin-8 (IL-8)≥90ng/L and 24 with it＜90 ng/L.METHODS: Sixty-eight patients with CLI received self-rating depression scale(SDS) and self-rating anxiety scale(SAS) testing made by Zung in one week before treatment. Statistical analysis of the scores was performed according to the classifications of age, sex, course of disease, pathological stages, types of carcinoma, and serum level of CEA and IL-8 respectively.MAIN OUTCOME MEASURES: ① The occurrence of depression and anxiety in CLI patients(standard scores of SDS and SAS were ≥50 ). ②The relationship between the standard scores of SDS and SAS and the various variables as age, sex, course of disease, pathological stages, types of carcinoma and serum level of CEA and IL-8.RESULTS: Totally 68 patients with CLI entered the statistical analysis procedure. ① The incidence of depression and anxiety(standard score ≥50) were 48% (33/68) and 43% (29/68) in patients with CLI. ② In patients with an age ＜55, male patients, and patients with a course of disease ≥10weeks, the standard scores of SDS(46.51 ±9.82, 47.74 ± 14.25, 48.38 ± 11.73) and SAS(44.28 ±11.24, 45.06±13.27, 45.78±12.59) were significantly higher than those in patients with an age ≥55,female, and with a course of disease ＜10 weeks(SDS: 43.27 ±10.06, 42.63±10.06, 42.19±14.34;SAS: 41.65±12.77, 41.22±10.89, 42.30±10.21) (t=2.192-2. 329, P ＜0.05). In patients in Dukes D stage of carcinoma, those with a cancer of anal canal and those with a nonsquamous carcinoma, the standard SDS scores(48.04±12.71, 47.23±9.85, 48.06±14.32) and SAS scores (44.96±10.13, 45.17±12.34, 45.28±14.38) were significantly higher than those in patients with Dukes A-C stages of carcinoma, with nonanal canal cancer, and with a squamous cell carcinoma(SDS: 43.42±11.97,44.05±12.14, 44.36±10.57; SAS: 42.23±13.04, 42.39±11.09,43.14±10.60) (t=2.136-2.298, P ＜0.05).In patients with serum level of CEA ≥30 μg/L and with IL-8 level ≥90 g/L,the standard scores of SDS(48.27±11.69, 49.04±12.24) and SAS(44.94±13.34,45.26±12.70) were significantly higher than those in patients with CEA ＜30μg/L and IL-8 ＜90 ng/L( SDS: 43.48±12.76, 44. 15±13.61;SAS: 41.47±10.58, 41.71±14.53) (t =2. 248-2. 314, P＜0.05).CONCLUSION: It is showed that those patients with these variables as a longer course of disease, an older age, male, a more advanced Dukes staging,and higher levels of CEA and IL-8 are prone to depression and anxiety.

Objective:To evaluate the effect of modified Tianma-Gouteng Decoction combined with conventional western medicine in the treatment of cerebral hemorrhage with syndrome of hyperactive liver yang causing wind. Methods:From May 2017 to December 2019, 120 patients of cerebral hemorrhage with syndrome of hyperactive liver yang causing wind were randomly divided into two groups, 60 in each group. The control group was treated with conventional western medicine treatment, and the observation group was with modified Tianma-Gouteng Decoction on the basis of the control group. Before and after treatment, the TCM symptom scores were evaluated. Serum norepinephrine (NE), epinephrine (E), dopamine (DA) were detected by ELISA. Serum MDA was detected by ELISA. Serum homocysteine (Hcy), endothelin (ET) were detected by fluorescence polarization immunoassay, the National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment, and Barthel index was used to assess activities of daily living. The rebleeding during the treatment was observed and recorded to evaluate the clinical efficacy. Results:The total effective rate was 90.0% (54/60) in the observation group and 70.0% (42/60) in the control group, with significant difference between the two groups ( χ2=7.500, P=0.006). After 3 and 6 weeks of treatment, the TCM syndrome score of the observation group were significantly lower than those in the control group ( t=10.670, 14.022, P<0.001). After treatment, NIHSS score of treatment group was significantly lower than that of control group ( t=5.736, P<0.01), Barthel index score of treatment group was significantly higher than that of control group ( t=10.559, P<0.01). After treatment, serum NE [(2 897.51 ± 241.65) pmol/L vs. (6 309.25±394.16) pmol/L, t=57.160], E [(1 352.45 ± 234.15) pmol/L vs. (4 131.20 ± 431.55) pmol/L, t=43.839] and DA [(623.59 ± 45.61) pmol/L vs. (950.61 ± 51.39) pmol/L, t=36.866] levels, serum SOD [(4.08 ± 1.05) C/μg·mgHb vs. (3.16 ± 1.02) C/μg·mgHb, t=4.868], MDA [(3.15 ± 1.41) μmol/L vs. (5.86 ± 1.31) μmol/L, t=10.907] levels, serum Hcy [(12.98 ± 2.41) μmol/L vs. (17.68 ± 2.26) μmol/L, t=11.019], ET [(51.36 ± 5.29) ng/L vs. (79.58±7.65) ng/L, t=23.502] in treatment group were significantly lower than those in the control group ( P<0.01); NO [(63.19 ± 3.87) μmol/L vs. (51.26 ± 3.59) μmol/L, t=17.506] in treatment group was significantly higher than that of the control group ( P<0.01). The incidence of rebleeding was 1.7% (1/60) in the observation group and 15.0% (9/60) in the control group, where the difference was statistically significant ( χ2=6.982, P=0.008). Conclusion:Modified Tianma-Gouteng Decoction combined with conventional western medicine therapy can protect the cerebral nerve function of patients with cerebral hemorrhage with syndrome of hyperactive liver yang causing wind, prevent the secondary ischemic brain injury after cerebral hemorrhage, and improve the clinical curative effect.

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.
