Objective To study the relationship between the (C 106T) single nucleotide polymorphsim of promoter region of aldose reductase gene and type 2 diabetes mellitus with nephropathy in Chinese Han from Chongqing. Methods The (C 106T) allele and genotype of 192 patients of type 2 diabetes were examined by polymerase chain reaction agarose gel electrophoresis and restriction enzyme Bfa Ⅰ. Results The frequencies of both allele C and genotype CC were significantly higher in type 2 diabetes patients with albuminuria than in those without albuminuria. Logistic regression analysis showed that allele C and genotype CC were associated with diabetic nephropathy in type 2 diabetes mellitus patients( P =0.032 and 0.046, respectively). Conclusion This finding suggests that (C 106T) single nucleotide polymorphism in the aldose reductase gene promoter region may be associated with diabetic nephropathy of Chinese Han type 2 diabetes. It may be a functional polymorphism and can serve as an inherited marker for susceptibility of diabetic nephropathy.

Objective To investigate the effect of the extracts of Centella asiatica(L.) Urban (ECA) on the depressive-like behavior alteration in rats and mice. Method 60 Wistar rats were randomly divided into 6 groups (10 rats each), the normal group, model group, Fluoxetine group, ECA high dose group (component 10.08 mg+component 24.48 mg/kg), ECA middle dose group (component 1 0.04 mg+component 2 2.24 mg/kg) and ECA low dose group component 1 0.02 mg+component 2 1.12 mg/kg. Chronic unpredictable mild stress (CUMS) induced depression in rats and sugar consumption to detect the antidepressant effect of ECU. 60 Kunming mice were randomly divided into six groups as above. Locomotor activity, forced swim, tail suspension test were used to detect the effect of ECA on the behavioral alteration in mice. Results Compared with model group, sugar consumption in ECA groups was significant increased (P<0.01). ECA treatments also decreased duration of immobility in the tail suspension test and forced swim. Conclusion ECA could improve the depressive-like behavior in rats and mice.

Objective:To study the adhesive strength between fiber posts and four different composite resin core materials.Methods:Four resin core materials (Multicore Heavy Body、LuxaCore、 LIGHT-CORE and Z100) were placed around the fiber posts. The adhesive strengths of the samples were tested by the universal electrical testing machine. The interface between fiber post and resin core was observed by SEM. Results:Different resin core materials exhibited significant different influences on adhesive strengths(P<0.05). The LuxaCore reached the maximum of (314.31±15.36) N and the Z100 was the minimum of (267.39±10.54) N.Conclusion:Resin core material exhibits a significant influence on adhesive strength. The dual-curing composite core material with low viscosity has the highest bond strength in all groups.

Objective To improve the diagnosis and treatment of adenocarcinoma of bladder. Methods The data of 20 cases of adenocarcinoma of bladder from 1986 to 2004 were retrospectively analyzed. All patients underwent operation and the diagnosis was proven by histopathologic examination. Results Eighteen cases were primary adenocarcinoma of bladder,8 cases applied to radical cystectomy and 10 cases partial cystectomy. Two cases were urachal adenocarcinoma,and received extended partial cystectomy.Seventeen patients were followed up for 3 months to 5 years. The one-year survival rate was 52.9% (9/17),two-year survival rate 41.2% (7/17),and five-year survival rate 29.4% (5/17). Conclusion Radical total cystectomy is the best choice for primary adenocarcinoma of bladder and extended partial cystectomy for urachal adenocarcinoma. Radiotherapy and chemotherapy after operation can improve the treatment effect.

Objective To study the effect and mechanism of tetrandrine (Tet) treatment of severe acute pancreatitis (SAP). Methods 45 SD rats were randomly divided into 3 groups: control group, severe acute pancreatitis group (SAP group) and tetrandrine group (Tet group). 5 rats were randomly taken from each group 3, 6, and 12 h after operation, and then underwent laparotomy for testing. Detection targets included calciumion concentration, pancreatic acinar calcium fluorescence intensity and pancreas pathological evaluation. Results In terms of the value of all detection targets, there was no statistical difference for the control group between different time points (P ＞0.05 )while there was statistical difference for SAP group and TET group in different time points (P＜0.05). Conclusion The experiment confirms that Tet, as a calcium blocker, can inhibit calcium to penetrate into pancreatic acinar cells, thus effectively reduce the pathological damage to pancreas of the experimental rats. Calcium overload plays an important role in SAP development.

Objective To explore the prevalence of age-related eye diseases (AREDs) among people aged 70 years or above in Hangzhou and evaluate the impact of AREDs on visual function (VF) and visual-related quality of life (QOL) in elders.Methods This study involved a total 2 111 elderly people (≥70 years).All participants received visual acuity and comprehensive eye examinations and complete VF and QoL questionnaires.Results The main cause of visual impairment was AREDs.And the causes were age-related cataract (79.82％),AMD (45.64％),glaucoma (10.95％) and diabetic retinopathy (DR,7.30％).VF and QoL scores declined gradually with age.And the scores declined more rapidly with declined visual acuity among the elders.VF and QoL scores in patients with age-related cataract,AMD,glaucoma and DR were successively lower.After adjusting for age,gender and visual acuity,the elders with AREDs had lower scores across all domains of VF and QoL.Scores for subscales of VF and QoL domains were significantly lower among those with DR and glaucoma compared with those with age-related cataract and AMD.Conclusion Age,presenting vision and AREDs are associated with VF and QoL in this elderly population.And senile people with glaucoma and DR have severe declines in VF and QoL,independent of presenting visual acuity.

Objective:To study the effect of early nursing intervention to prevent lymphedema of upper limb after breast cancer surgery and its effect on postoperative quality of life.Methods:Between July 2018 and March 2020, one hundred and seventeen cases of breast cancer, all female, admitted to department of thyroid and breast surgery, the affiliated Zhongshan hospital of Dalian University, were underwent modified radical mastectomy with axillary lymph node dissection. Fifty-eight cases were included in the control group whereas fifty-nine cases were in the intervention group. The control group received conventional nursing, the intervention group added early care intervention measures on the basis of conventional nursing. Follow-ups were carried out monthly in a period of 9 months post-surgery. The incidence and grade of lymphedema were compared between the two groups.Results:The incidences of lymphedema at 1,3,9 months after surgery were 8.5% (5/59), 8.5% (5/59), 10.2% (6/59) in the intervention group, which were lower than 31.0% (18/58), 36.2% (21/58), 43.1% (25/58) in the control group. Statistics showed significant difference between the two groups ( χ2 value was 9.425, 13.041, 16.289, P<0.05). The incidence of mild, moderate, and severe lymphedema were statistically different between the two groups ( χ2 value was 10.350, 12.078, 17.422, P<0.05). Follow-up for the quality of life was assessed using a 5-dimension evaluation method, including physical status, social/family status, emotional status, functional status and additional attention. One month follow-up showed 20.36±1.80, 20.03±1.68, 34.63±3.52, 15.86±1.96, 19.81±1.04 in the intervention group, all higher than the control group 17.03±1.36, 17.10±1.46, 19.38±1.51, 10.91±1.22, 18.36±1.21. Three-month follow-up showed 23.56±2.72, 23.73±2.20, 39.93±4.17, 20.31±3.04, 26.37±2.23 in the intervention group, higher than those of the control group 20.90±2.14, 19.12±2.63, 25.79±3.59, 13.97±2.67, 21.02±2.50. Nine month follow-up showed 27.44±2.01, 25.80±1.85, 40.88±3.72, 21.02±2.78, 27.02±2.45 in the intervention group, which were high than the control group 19.93±1.66, 20.67±1.46, 19.38±2.29, 16.33±2.65, 22.29±2.52. The difference between the two groups were statistically significant ( t value was 8.691-34.383, P<0.05).

Objective To investigate the regulation of protein kinase C(PKC) to the expression of β-1,4-galactusyhransferase- Ⅰ ( β-1,4-GalT- Ⅰ ) and the influence on cytoskeleton and adherence ability of human umbilical vein endothelial cells(HUVECs) when stimulated by lipopolysaccharide (LPS). Methods Cultured HUVECs were pretreated by various PKC inhibitors or phorbol 12-myristate 13-acctate( PMA), an excitomotor of PKC respectively for 30 min, then stimulated by LPS for 4 h. β-1,4-GalT-Ⅰ expression were detected by RT-PCR and Western blot, expression of β-1,4-galactosylated carbohydrate chains and cytoskeleton were assayed by immumofluorescence, and adherence ability of HUVECs was observed by endothelialmonocyte cell adherence test. Results Up-regulated expression of β-1,4-GalT- Ⅰ and β-1,4-galactosylated carbohydrate chains in HUVECs stimulated by LPS were suppressed by PKC inhibitors and increased by PMA. F-actin and β-1,4-GalT- Ⅰ were partly co-localized in HUVECs. PKC inhibitor inhibited the effect of LPS on the distribution of F-actin and β-1,4-GalT- Ⅰ. Adherence ability of HUVECs enhanced by LPS was significantly suppressed by PKC inhibitor. Conclusion PKC signal transduction pathway may participate in regulating β-1,4-GalT-Ⅰ expression in endothelial cells stimulated by LPS. Furthermore, polytypes of PKC may participate in this regulating process; PKC might regulate cytoskeleton reorganization and adherence ability of EC through β-1,4-GalT-Ⅰ during inflammation.
