Objective To explore the correlation between serum homocysteine(Hcy) levels and behavioral and psychological symptoms dementia (BPSD) in patients with mild to moderate vascular dementia (VaD).Methods Two hundred and ninety-three patients with mild to moderate vascular dementia (aged 40 or over) admitted to the department of neurology of the First Affiliated Hospital of Liaoning Medical College from January 2012 to January 2015.Patients were diagnosed with dementia by NINDS-AIREN criteria,MMSE scores ≤26,Hachinski ischemic scale(≥4) and clinical dementia rating(1≤ C DR ≤ 2).VaD patients were divided into high Hcy(HHcy) group (Hcy≥ 15 μ,mol/L,n=188) and control group(Hcy＜15 μmol/L,n=105).The total scores and the scores of 12 functional domains of behavioral and psychological symptoms in NPI were analyzed by using comparative statistical methods.Results Prevalence of high homocysteine was 64.16％ (n=188) among mild to moderate VaD (n=293).The incidence of BPSD in HHcy group(80.9％) was significantly higher than that in the control group (57.1％),the difference was statistically significant (x2=18.932,P＜0.01).HHcy patients (27.95±5.04) had a significantly higher total score of NPI compared with control patients (16.87± 1.87),the difference was statistically significant (t=3.753,P＜0.01).In terms of scores in 12 functional domains in NPI,the scores in sleep disorders (2.99± 1.40),high (2.10±0.53),irritability/mood swings (2.64± 1.43),abnormal behavior (1.74±0.52),disinhibition (1.40±0.43),agitation (2.02±0.74) were higher than those in control groups (1.85±0.37,0.21±0.05,1.80 ±0.56,0.36±0.09,0.45±0.07,0.68±0.23),all the difference were significant(t=2.327,t=2.012,t=2.136,t=2.066,t=2.050,t=2.007,all P＜0.05).Binary logistic regression analysis showed that there were positive correlation between scores of NPI and plasma Hcy levels (OR=1.164,95％ CI:1.052-1.288,P=0.003).Compared with HHcy group and control group,there were no statistical significance in regard to infarcted brain focus including the frontal lobe,parietal lobe,temporal lobe,occipital lobe,basal ganglia,brain stem and cerebellum (x2=0.528,x2=0.043,x2=0.630,x2=0.166,x2=0.657,x2=1.010,x2=0.019,allP＞0.05).Conclusion High homocysteine levels are correlated with behavioral and psychological symptoms in patients with mild to moderate VaD,including performance of sleep disorders,high,irritability/mood swings,abnormal behavior,disinhibition and agitation.Moreover,the severity of BPSD is positively associated with homocysteine levels.The higher the homocysteine level,the more severe the BPSD.The serum homocysteine levels are no correlated with infarcted brain focus.

Objective To observe the expression level change of vascular endothelial growth factor (VEGF) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS), and to explore the relationships of VEGF expression with OSAHS, OSAHS related cardiovascular and cerebrovascular diseases. Methods Polysomnography (PSG) was used to conduct sleep apnea monitoring in 24 OSAHS patients from 6OSAHS popular families and 48 healthy controls with normal physical examination results. The expression of VEGF mRNA was examined by reverse transcriptionpolymerase chain reaction (RT-PCR) analysis, meanwhile, the level of VEGF in plasma was measured VEGF mRNA in PBMC were significantly higher in simple OSAHS group [plasma levels: (205.75±2.79) pg/ml; mRNA: 0. 61±0. 02] than in control group [(168.72±4.64) pg/ml; 0. 47±0. 02,cardiovascular and cerebrovascular diseases group [(288.74 ± 2.73) pg/ml, 1.16 ± 0. 03] than in simple OSAHS group [ ( 205.75 ± 2.79 ) pg/ml, 0. 61 ± 0.02, P ＜ 0. 01]. ( 2 ) There was a positive correlation of the levels of VEGF in plasma and mRNA with AHI as well as systolic and diastolic blood pressure in early morning. There was a negative correlation of the level of VEGF in plasma and VEGF mRNA with the lowest saturation of blood oxygen. There was a positive correlation of the level of VEGF mRNA with AHI as well as systolic and diastolic blood pressure in early morning.Conclusions The level of VEGF in OSAHS significantly increases, which may play a role in the pathophysiology of OSAHS and OSAHS related cardiovascular and cerebrovascular diseases.

Objective To investigate the effects of urotensin Ⅱ/urotensin Ⅱreceptor ( UⅡ/UT) system on the expression of inflammatory signal molecules p 38 mitogen-activated protein kinase ( p38 MAPK) and nuclear factor-κB ( NF-κB ) in lipopolysaccharide ( LPS )-stimulated Kupffer cells ( KCs ) . Methods Rat KCs were isolated and purified by means of in situ perfusion and density gradient centrifuga-tion.The isolated cells were randomly divided into six treatment groups including group 1:UⅡ(-) urantide (-)LPS(-), group 2:UⅡ(+)urantide(-)LPS(-), group 3: UⅡ(-)urantide(+)LPS(-), group 4:UⅡ(-)urantide(-)LPS(+), group 5:UⅡ(+) urantide(-) LPS(+) and group 6:UⅡ(-)urantide(+) LPS(+) .Western blot assay was performed to detect p 38 MAPK/p-p38 MAPK protein and NF-κB p65 sub-unit.The DNA-binding activity of NF-κB was tested by electrophoretic mobility shift assay (EMSA).Re-sults There was no significant difference with the expression of p 38 MAPK protein in KCs among the six groups (P>0.05).The expression of p65 protein and p-p38 MAPK and the DNA-binding activity of NF-κB were significantly enhanced in LPS-stimulated KCs from groups 4, 5 and 6 in comparison with those in group 1 (P<0.01).No significant differences with the levels of p65 protein and phosphor-p38 MAPK and the DNA-binding activity of NF-κB were observed between UⅡ/urantide-treated cells ( group 2 or group 3) and untreated cells (group 1) (all P>0.05), but that were decreased in group 6 than those in group 4 (all P<0.01).Conclusion UⅡ/UT system participated in the activation of p38 MAPK and NF-κB signaling pathways in LPS-stimulated primary Kupffer cells .

Objective:To observe the efficacy of gentle moxibustion combined with Western medicine in treating rheumatoid arthritis(RA)due to damp heat affecting bones/joints to further certificate the scientific nature of the theory that"heat pattern can be treated by moxibustion therapy". Methods:A total of 78 patients with RA due to damp heat affecting bones/joints were divided into an observation group and a control group using the random number table method,with 39 cases in each group.The control group was treated with regular Western medicine,on the basic of which the observation group was treated with additional gentle moxibustion.Patients in the observation group received gentle moxibustion therapy once a day for 8 weeks with a one-day rest every 2 weeks.The wrist circumference,wrist pain degree,skin color and temperature of the wrist,and range of dorsiflexion motion of the wrist in the two groups of patients were compared before and after treatment under the condition of safety observed. Results:The total effective rate in the observation group was 94.9%,which was higher than the result of 79.5%in the control group(P<0.05).Among the quantitative indicators of syndrome differentiation,the wrist circumference,pain degree,skin temperature,and range of dorsiflexion motion in both groups were significantly improved(P<0.01),and the improvements were more significant in the observation group than in the control group(P<0.05).The skin color of the wrist joint was improved in both groups after treatment(P<0.05),and there was no statistical significance in comparing the improvement of skin color and the occurrence of adverse reactions between the two groups(P>0.05). Conclusion:Compared with Western medicine treatment alone,the combination of gentle moxibustion and Western medicine treatment has significantly better treatment efficacy and shares high safety,which helps to prove the scientific nature of the theory that"heat pattern can be treated by moxibustion therapy".

Objective:To analyze the supervision mode and problems of intensive countywide medical communities and explore the methods and strategies to improve their supervision system.Methods:From March 2022 to May 2022, a stratified random sampling method was used and the intensive countywide medical communities in the province were selected for field study. In-depth interviews were made with the staff of the healthcare administration departments and health insurance agencies affiliated with intensive countywide medical communities, directors of general hospitals, directors of township hospitals, and heads of functional departments. These interviews mainly covered the principal entities of countywide medical community supervision, supervision measures and contents, supervision effects, supervision weaknesses, and how to improve internal and external supervision mechanisms. The interviews results were analyzed using thematic framework analysis and the data were subject to a descriptive analysis.Results:23 persons of five intensive countywide medical communities were selected for key person interview. The finalized framework of regulatory elements of intensive countywide medical communities consists of such five general themes as regulatory subjects, regulatory content, regulatory measures, regulatory effectiveness and existing problems, comprising 14 level-1 indicators and 52 level-2 indicators. The main regulatory bodies were mainly government departments (15 times), the regulatory content was focused on medical resources (10 times), the regulatory measures cover specific regulations (4 times), specific activities (4 times) and assessment and evaluation (4 times). And the regulatory effectiveness demonstrated a currently strong regulation strength of medical communities (5 times), and the existing problems were insufficient government supervision (12 times), difficulties encountered by social forces in their supervision (11 times) and internal governance (5 times).Conclusions:The supervision system of intensive countywide medical communities should be optimized by improving the governmental supervision mechanism, inviting supervision of social forces and building an effective internal governance.

Objective:To analyze the expression level of minichromosome maintenance protein 6 (MCM6) in colon cancer tissues, the correlation between the expression level of MCM6 and the clinicopathological characteristics of colon cancer patients, and the correlation between MCM6 and PCNA expression.Methods:The expression levels of MCM6 in different tumor tissues were analyzed based on the Human Protein Atlas (HPA) database. The expression levels and correlations of MCM6 and PCNA in colon cancer tissues were analyzed based on The Cancer Genome Atlas (TCGA) database and immunohistochemical experiments. The correlation between MCM6 expression level and clinical characteristics of colon cancer patients was analyzed. The correlation between MCM6 and PCNA expression in colon cancer was analyzed based on TCGA database and Gene Expression Profile Interaction Analysis (GEPIA) database.Results:Bioinformatics analysis and immunohistochemical results confirmed that MCM6 was highly expressed in colon cancer tissues, and its expression level was correlated with the tumor stage of patients ( P=0.01). In colon cancer, the expression of MCM6 and PCNA was correlated with statistical significance ( P<0.05). Conclusions:MCM6 is highly expressed in colon cancer tissue and is related to the clinical characteristics of patients, suggesting that MCM6 can be used as a potential marker of colon cancer.

To examine the efficacy and safety for metformin in treating antipsychotic-induced dyslipidemia.
 Methods: Two randomized placebo-controlled trials were included in the analysis. A total of 201 schizophrenia patients with dyslipidemia after treatment with an antipsychotic were collected, and the patients were divided into two groups: a 1 000 mg/d metformin group (n=103) and a placebo group (n=98). The clinical symptoms and metabolic indicators such as body weight, blood glucose, and blood lipids were assessed at baseline, the 12th week and the 24th week after treatment respectively.
 Results: After metformin treatment, the mean difference in the low-density lipoprotein cholesterol (LDL-C) value between the metformin group and the placebo group was from 0.16 mmol/L at baseline to -0.86 mmol/L at the end of the 24th week, which was decreased by 1.02 mmol/L 
(P<0.01). At the 24th week, the LDL-C was more than 3.37 mmol/L in 25.3% patients in the metformin group, which was significantly lower than that in the placebo group (64.8%) (P<0.01). Compared with the placebo group, there were significant changes in the weight, body mass index (BMI), insulin, insulin resistance index, total cholesterol and triglyceride, and high-density lipoprotein cholesterol (HDL-C) in the metformin group (all P<0.05). The treatment effects on weight and insulin resistance appeared at the 12th week and further improved at the 24th week, but the effects on improving dyslipidemia only significantly occurred at the end of the 24th week.
 Conclusion: The metformin treatment is effective in improving antipsychotic-induced dyslipidemia and insulin resistance, and the effect to reduce the antipsychotic-induced insulin resistance appears earlier than the effect to improve dyslipidemia.
