Objective:To evaluate the effect of self-management model of community diabetes patients under the guidance of general practitioners.Methods:A total of 22 communities in Hangzhou were selected as intervention pilot from 2016 to 2017, and 10-15 diabetic patients were recruited to form a self-management team in each community. Relying on the construction of medical alliance and there sources of contracted service of family doctors, intervention teams were set up to conduct regular, personalized and continuous self-management interventions on patients. Intervention continued for 4-6 months. Before, after and 6 months after the intervention, the basic information of patients, knowledge of diabetes, faith in managing disease, self-management behavior, self-management ability of patients, and quality of life were collected through questionnaire survey, body mass index (BMI), 2-hour postprandial blood glucose and glycosylated hemoglobin were detected uniformly, and statistical analysis was conducted.Results:A total of 292 patients were involved in the self-management group, the average age was (66.38±7.90) years old, most of them were female (64.73%). Six months after the intervention, the awareness rate of basic knowledge, risk factors and prevention and treatment knowledge about diabetes in patients (68.64%, 78.75%, 63.41%) were significantly higher than those before the intervention (28.08%, 48.29%, 39.38%), the proportion of patients with reasonable diet, moderate exercise, active problem-solving, management plan making and action according to the plan increased (from 65.41%, 28.76%, 39.04%, 31.85%, 27.74% to 86.76%, 60.28%, 65.16%, 78.05%, 73.17%)(all P<0.05).In terms of time effect, the scores of physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional and mental health in SF-36 after intervention and 6 months after intervention were all increased step by step (all P<0.05). Before the intervention, BMI, 2-hour postprandial blood glucose and glycosylated hemoglobin were (24.20±3.11) kg/m 2, (9.29±2.23) mmol/L, (6.81±1.01)% respectively. After the intervention, the three indexes all showed a downward trend, which were (22.89±2.98) kg/m 2, (8.81±1.61) mmol/L, (6.57±0.76)% respectively ( F=14.832, 6.828, 9.667; all P<0.05). Conclusion:Under the guidance of general practitioners, the self-management model of community diabetes patients can effectively improve the level of recognition, belief and behavior of patients, improve their self-management ability and quality of life, and improve BMI and blood glucose control level.

Objective:To analyze the mediating effects of emotional changes in self-management interventions on the relationship between behavioral management and quality of life in elderly patients with type 2 diabetes and therefore to provide a reference for improving the emotional status of elderly diabetes patients and future community-based self-management interventions.Methods:From 2016 to 2020, a total of 69 self-management groups were formed in Hangzhou, each consisting of 10-15 patients with type 2 diabetes.Based on the construction of a medical consortium and family doctors signing up to provide services, intervention teams were established to conduct a series of group self-management activities for each group.Surveys via questionnaires were conducted before and after the intervention, as well as 6 months after the intervention, to collect patient data on demographics, disease status, emotions, quality of life, and self-management behaviors.The intervention effects were evaluated, and the correlations between emotional changes, self-management behaviors, and changes in quality of life were analyzed.Bootstrap analysis was used to test the mediating effects.Results:A total of 707 elderly diabetes patients were included.There were statistically significant differences in the scores of the Self-Rating Anxiety Scale(SAS), the Self-Rating Depression Scale(SDS), physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, physical component summary, mental component summary, the dietary control dimension of the type 2 diabetes self-care scale(2-DSCS), regular exercise, medication adherence, blood glucose monitoring, foot care, the dimension of prevention and management of hyperglycemia and hypoglycemia, and the total score of 2-DSCS( P<0.05 for all).Compared with pre-intervention, changes in SAS, SDS, physical component summary and mental component summary scores were all correlated with each dimension of 2-DSCS right after intervention and 6 months after intervention( r=-0.336-0.333, P<0.05), with the exception of changes in the blood glucose monitoring dimension score and changes in the emotional status score.The direct effect of self-management behavior on the quality of life in elderly patients with type 2 diabetes was 0.159, and the indirect effect through emotions was 0.229, with the mediating effect accounting for 59.02% of the total effect. Conclusions:Community-based group self-management activities can effectively improve the emotions and management behaviors of elderly diabetes patients and enhance their quality of life, Emotional changes play a certain mediating role between self-management behaviors and improvement in quality of life.

This study was aimed to investigate whether the extracts of Celastrus orbiculatus enhanced the invasion function of maspin tumor inhibitor gene through the construction of maspin overexpression human gastric carcinoma MGC803 cell line. Maspin was cloned into plasmid GV208-EGFP eukaryotic expression vector. And then, the recombinant plasmid GV208-maspin-EGFP was transfected into human gastric carcinoma MGC803 cells. After the maspin overexpression MGC803 cell were treated with Celastrus orbiculatus extracts in different concentrations (10, 20, 40 μg·mL-1), the invasion effects were detected by Transwell chamber assay. The results showed that after the successful construction of maspin overexpression cell line, the number of cells invading through Matrigel was obviously decreased in the Transwell chamber assay. It also showed drug concentration dependency. It was concluded that maspin gene can inhibit invasion of gastric carcinoma MGC803 cells. Simultaneously, the extracts of Celastrus orbiculatus can enhance the function of maspin gene.

Objective To evaluate the safety and efficacy of transplantation of purified CD34 + cells (PCCs) in treatment of critical limb ischemia (CLI) caused by thromboangiitis obliterans (TAO).Methods From May 2009 to June 2015,34 TAO-induced-CLI cases underwent PCCs transplantation.None of these patients were eligible for surgical or endovascular revascularization.G-CSF was subcutaneously injected for 5 days before peripheral CD34 + cells were isolated,purified and intramuscularly injected in the limbs.Patients were regularly follow-up.Results Technical success was achieved in all cases.The mean number of transplanted cells was (7.5 ± 2.4) × 105/kg.The follow-up was accomplished in 32 cases,ranging from 6 to 79 months (mean 45 ±24 months),and two patients were lost.Wong-Baker FACES pain rating scale score significantly decreased from 8.0 ±2.0(4-10)to 2.2 ±3.1 (P ＜0.05) at 1 month.The Peak pain-free walking time improved from (4.0 ± 2.0) min to (13.5 ± 5.3) min (P ＜ 0.05) at 3 months and (19.0 ± 3.1) min (P ＜ 0.05) at 6 months.The ankle-brachial index increased from 0.42 ± 0.20 to 0.50 ± 0.10 (P ＜ 0.05) at 3 months and 0.52 ± 0.11 (P ＜ 0.05) at 6 months,respectively.Transcutaneous partial oxygen pressure rose from (25 ± 11) mmHg to (48 ± 11) mmHg(P ＜ 0.05) at 3 months and (58 ± 10) mmHg (P ＜ 0.001) at 6 months,respectively.Ulcers healed in 21 out of 22 patients at (5 ± 4) months.The overall amputation-free survival rate was 94.1％ at 6 months and 91.2％ at 48 months.No major adverse events were observed perioperatively or postoperatively.Conclusions Transplantation of PCCs could yield safe,satisfactory and durable treatment outcomes in patients with TAO-induced-CLI.

OBJECTIVETo evaluate the therapeutic effects of combination administration of hydrochlorothiazide and nitrendipine at low dosage in the treatment of rural hypertension patients.

METHODSBy the method of cluster random sampling, 5292 primary hypertension patients from Fuxin, Liaoning Province were divided into health education group (control group) and drug intervention group in June 2006. The drug intervention group were treated with hydrochlorothiazide, nitrendipine and captopril by stepwise approach and we observe the antihypertensive effect of drug and the effect on the onset of stroke.

RESULTSThe average follow-up time was 15 months. At last, 308 patients were lost to follow-up (the lost follow-up rate was 5.8 percent). The 4984 in cohort, including 2530 of intervention group and 2454 of control group, had examination of all indicators. Through health education and drug intervention, the average blood pressure in drug intervention group decreased by 16.1/9.4 mm Hg (1 mm Hg = 0.133 kPa) while the average blood pressure in control group decreased by 6.7/3.5 mm Hg. The control rate of blood pressure in drug intervention group was higher than control group (33.1% vs. 15.1%, P < 0.001). Through drug intervention, the morbidity risk of nonfatal stroke in drug intervention group decreased by 57.3% compared to control group, the total morbidity risk of stroke decreased by 59.4%. The results had significant statistical difference. And, the morbidity of severe hypopotassaemia (K(+) < 3.0 mmol/L) and diabetes mellitus had no significant statistical difference between two groups.

CONCLUSIONSThe low-cost antihypertensive program based on thiazide had good antihypertensive effect, high safety and good cost-effect ratio. The program could be used in rural areas of China.

OBJECTIVETo optimize the animal model of liver injury that can properly represent the pathological characteristics of dampness-heat jaundice syndrome of traditional Chinese medicine.

METHODSThe liver injury in the model rat was induced by alpha-naphthylisothiocyanate (ANIT) and carbon tetrachloride (CCl(4) ) respectively, and the effects of Yinchenhao Decoction (, YCHD), a proved effective Chinese medical formula for treating the dampness-heat jaundice syndrome in clinic, on the two liver injury models were evaluated by analyzing the serum level of alanine aminotransferase (ALT), asparate aminotransferase (AST), alkaline phosphatase (ALP), malondialchehyche (MDA), total bilirubin (T-BIL), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) as well as the ratio of liver weight to body weight. The experimental data were analyzed by principal component analytical method of pattern recognition.

RESULTSThe ratio of liver weight to body weight was significantly elevated in the ANIT and CCl(4) groups when compared with that in the normal control (P<0.01). The contents of ALT and T-BIL were significantly higher in the ANIT group than in the normal control (P<0.05,P<0.01), and the levels of AST, ALT and ALP were significantly elevated in CCl(4) group relative to those in the normal control P<0.01). In the YCHD group, the increase in AST, ALT and ALP levels was significantly reduced (P<0.05, P<0.01), but with no significant increase in serum T-BIL. In the CCl(4) intoxicated group, the MDA content was significantly increased and SOD, GSH-PX activities decreased significantly compared with those in the normal control group, respectively (P<0.01). The increase in MDA induced by CCl(4) was significantly reduced by YCHD P<0.05).

CONCLUSIONYCHD showed significant effects on preventing liver injury progression induced by CCl(4), and the closest or most suitable animal model for damp-heat jaundice syndrome may be the one induced by CCl(4).

Objective To probe into the pre-operative design and the operative approach dealing with anastomotic vein and superior sagittal sinus in patients with large meningiomas in the sagittal sinus and falx cerebri. Methods Thirty-five patients with large meningiomas in the sagittal sinus and falx cerebri, admitted to our hospital from January 2001 to December 2010, were chosen; their clinical data were analyzed retrospectively. The resection of the tumors by microsurgery (total or subtotal resection) was performed and intraoperative effective management of the sagittal sinus and falx cerebri was done. Results Resection was performed in these 35 patients, including Simpson grade Ⅰ in 21(60.0％), grade Ⅱ in 12 (34.2％), and grade Ⅲ in 2 (5.7％). Skull defect was noted in 5 patients. Unilateral　paralysis of limbs (muscle strength grade Ⅰ-Ⅳ) in 5; paralysis of both lower extremities (muscle strength grade Ⅰ-Ⅱ) in 1; good results were achieved after 1-6 months of hyperbaric oxygen, acupuncture and physiotherapy. During the follow-up period for 6 to 24 months, the tumor recurred in 2 with Simpson Ⅲstage resection (5.7％). Conclusion Designing a detailed pre-operative design according to the MRI,MRA, DSA and CTA, application of microsurgical techniques, avoidance of damage to the cerebral cortex and veins of central suleus and protection of the sagittal sinus are important factors that increase the success rate of surgical resection, reduce complications, prevent the tumor recurrence and improve the survival outcome in patients with parasagittal meningiomas.
