Objective:To evaluate the status quo and influencing factors of hyperlipidemia management in patients with contracted family doctor service in the community.Method:The baseline data and blood lipid testing results of 752 hyperlipidemia patients (334 males and 418 females) with contracted family doctor service in Yuetan Community Health Service Center from November?2019 to May 2020 were collected. The hyperlipidemic patients were managed by family doctors based on atherosclerotic cardiovascular diseases(ASCVD) riks assessment. The ASCVD risk levels and low-density lipoprotein cholesterol (LDL-C) compliance rate of patients with different general data were compared, and the influencing factors of LDL-C control failure were analyzed by logistic regression.Results:The ASCVD risk assessment showed that among 752 patients there were 172 cases of low risk(22.87%), 167 cases of moderate risk(22.21%),352 cases of high risk(46.81%) and 61 cases of extremely high risk(8.11%). A significant difference was detected in sex,rate of smoking,incidence of overweight or obesity among patients with different ASCVD risk levels ( P<0.05).The overall control rate of LDL-C was 48.8% (367/752), that for low, moderate, high and extremely high risk patients were 83.73% (144/172), 53.89% (90/167), 34.38% (121/352) and 19.67%(12/61), respectively. A significant difference was detected in sex(female: 52.87%, 221/418),age(aged over 80: 58.82%, 110/187), rate of smoking (non-smoking:52.40%, 327/624) and medication compliance (good compliance:52.87%,221/418) between LDL-C control and uncontrol groups (χ2=6.323,11.816,19.022,25.274; P<0.05). Multiple logistic regression analysis revealed that male gender ( OR=1.800,95% CI:1.325-2.419), smoking ( OR=2.630,95% CI:1.726-4.007) and poor medication compliance ( OR= 2.179, 95% CI: 1.581-3.003) were independent risk factors for uncontrolled LDL-C levels. Conclusion:Patients with hyperlipidemia have a relatively high risk of cardiovascular diseases, and their blood lipids are not well controlled. The management of blood lipid should be enhanced in patients with chronic diseases, particularly for male patients with smoking and poor medication compliance.

Objective To evaluate dynamic graciloplasty (DGP) for canine in situ anal reconstruction. Methods Seventeen dogs were randomly divided into experimental group and control group. In control group, on the stage 1, the gracilis muscle were dissected in situ, manometry performed intraoperatively; In experimental group, the gracilis muscle were dissected in situ and stimulated chronically starting 7 days postoperatively. On stage 2, abdominoperineal resection of anus and graciloplasty for anal reconstruction were performed in two groups. After 2 weeks recovery, manometry and muscular fatigue-resistant curve (MFRC) were observed while myostimulator is switched off and on. The muscle of neosphincter was biopsied. Results After chronic low frequency electrical stimulation (CLFS), the percentage of type Ⅰ fibers in the stimulation group was higher than the control group (P0.05), but functioning neosphincter pressure is different significantly (P

Objective To explore the effect of adenovirus carrying pigment epithelium-derived factor(ADV-PEDF)gene treatment on retinal neovascularization of mice with retinopathy of prematurity (ROP).Methods Sixty 7 d C57BL/6J mice were put into the environment with (750?5)mL/L oxygen for 5 days and returned to normal environment to establish animal models of ROP.The eyes in experimental group received an intravitreal injection of 1 ?L of ADV-PEDF,and the same volume of ADV-LacZ was injected into the eyes of mice in control group.The ADPase histochemical staining was used for retinal flatmount to observe changes of retinal vessels.The inhibitory effects of PEDF on retinal neovascularization were evaluated by counting the endotheliocyte nuclei of new vessels extending from retina to vitreous in the tissue-slice.The expression of PEDF in retina were detected by Western blotting.Results The vessels from optic disc were very thin and distorted in eyes of control group in retinal flatmount.There were avascular area around optic disc and neovascular trufts beside avascular area.Compared with control group,regular distributions and no conspicuous avascular area were found in eyes of experiment group in retinal flatmount.The number of the endotheliocyte nuclei of new vessels extending from retina to vitreous was less in the eyes of the experiment group than that in control group (P

The present study aimed to investigate the effects of interleukin-1β (IL-1β) at different doses on collagen synthesis and decomposition in cultured cardiac fibroblasts from neonatal Sprague-Dawley rat. Cardiac fibroblasts were treated with IL-1β (0.01, 0.1, 1, 10, 100 ng/mL) for 24 h. Cell DNA synthesis was measured by (3)H-thymidine ((3)H-TdR) incorporation and collagen synthesis was measured by (3)H-proline ((3)H-Pro) incorporation. Matrix metalloproteinase (MMP) activity was measured by gelatinase zymography. MMP-2, MMP-9 protein expressions were measured by Western blot. mRNA expressions of MMP-2 and MMP-9 were detected by reverse transcription-polymerase chain reaction (RT-PCR). Compared with that in the control group, the incorporation of (3)H-TdR and (3)H-Pro decreased in high-dose IL-1β groups (≥0.1 ng/mL) but not in low-dose IL-1β group (0.01 ng/mL). IL-1β significantly increased MMP-2 and MMP-9 activities. IL-1β (0.01-100 ng/mL) also dose-dependently increased the protein and mRNA expressions of MMP-2 and MMP-9 (P<0.05, P<0.01), respectively. These results suggest that IL-1β decreases collagen synthesis and MMP activities through transcriptional and posttranslational processes via degrading collagen in a dose-dependent way. Elevation of IL-1β is possibly involved in the process of ventricular remodeling after myocardial infarction, and the concentration of IL-1β is possibly a major factor which affects the extent of ventricular remodeling.

OBJECTIVETo observe the effects of acupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) on distribution taxis of paclitaxel in mice with lung cancer to discuss targeted relationship between acupoints and corresponding viscera.

METHODSAccording to randomized digital table, 315 SPF-grade BALB/C female mice were divided into 7 groups: blank group (group A), model group (group B), medication group (group C), acupuncture at non-acupoint group (group D), acupuncture at Feishu group (group E), acupuncture at Lingtai group (group F) and acupuncture at Feishu and Lingtai group (group G), 45 mice in each one. Except the blank group, the remaining groups were treated with N-nitroso-tris-chloroethyl urea (NTCU) to establish the model of squamous-cell carcinoma. After model establishment, group A, group B and group C were not treated with acupuncture; group A and group B were treated with intraperitoneal injection of 0.9% sodium chlorvde solution by 6 mL/kg while group C was treated with intraperitoneal injection of paclitaxel by 6 mL/kg. The group D, group E, group F and group G were treated with acupuncture at non-acupoint, "Feishu" (BL 13), "Lingtai" (GV 10) and "Feishu" (BL 13) plus "Lingtai" (GV 10), respectively, then were intraperitoneally injected with paclitaxel by 6 mL/kg. The treatment was all given once a day for continuous 10 days. 15 min, 30 min, 1 h, 2 h, 8 h, 12 h and 24 h after the treatments, 6 mice in each group were randomly selected and sacrificed to collect samples of lung, liver, spleen, kidney and heart, etc. High performance liquid chromatography was applied to measure the concentration of paclitaxel in each organ (lung, liver, spleen, kidney and heart) at different time points.

RESULTS(1) The content of paclitaxel in lung, kidney and heart reached the peak at 2 h, then decreased significantly in group C, group D, group E, group F and group G; the content of paclitaxel in spleen showed downtrend at each time point. The content of paclitaxel in liver reached the peak at 2 h in group C and group D; the content of paclitaxel reached the peak at 8 h in group E, group F and group G. (2) The content of paclitaxel in lung in group E and group G was higher than that in group C and group D at each time point (all P < 0.01); the content of paclitaxel in lung in group F was higher than that in group C (P < 0.01) and group D (P < 0.01) only at time point of 2 h. The content of paclitaxel in lung in group G was higher than that in group F at each time point (all P < 0.05). There was no statistical difference between group G and group E (all P > 0.05).

CONCLUSIONAcupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) could influ- ence the metabolism of paclitaxel in lung-cancer mice, leading to distribution change in each organ. As a result, it could cause targeting effects, which is more significant at "Feishu" (BL 13) and "Lingtai" (GV 10).

This study was aimed to establish a stable animal model of left ventricular hypertrophy (LVH) to provide theoretical and experimental basis for understanding the development of LVH. The abdominal aorta of male Wistar rats (80-100 g) was constricted to a diameter of 0.55 mm between the branches of the celiac and anterior mesenteric arteries. Echocardiography using a linear phased array probe was performed as well as pathological examination and plasma B-type natriuretic peptide (BNP) measurement at 3, 4 and 6 weeks after abdominal aortic constriction (AAC). The results showed that the acute mortality rate (within 24 h) of this modified rat model was 8%. Animals who underwent AAC demonstrated significantly increased interventricular septal (IVS), LV posterior wall (LVPWd), LV mass index (LVMI), cross-sectional area (CSA) of myocytes, and perivascular fibrosis; the ejection fraction (EF), fractional shortening (FS), and cardiac output (CO) were consistently lower at each time point after AAC. Notably, differences in these parameters between AAC group and sham group were significant by 3 weeks and reached peaks at 4th week. Following AAC, the plasma BNP was gradually elevated compared with the sham group at 3rd and 6th week. It was concluded that this modified AAC model can develop LVH, both stably and safely, by week four post-surgery; echocardiography is able to assess changes in chamber dimensions and systolic properties accurately in rats with LVH.

Objective To explore the relationship between social participation and needs for rehabilitation of the disabled in Guangdong Province and to make a proposal for developing the rehabilitation strategies. Meth-ods The data of the Second National Sample Survey of Disabled Persons in Guangdong Province was used in this study. Ranked data analysis was made with the sub-items of the social participation assessment and the main needs of the disabled individuals. Results Significantly statistical differences were revealed with regard to the constitu-ent ratio of needs for rehabilitation services among people with different degrees of difficulties in social participation caused by hearing and visual impairments as well as physical and mental disabilities. No significant difference was found in terms of the constituent ratio of rehabilitation needs among those with difficulties in speech and those with psychiatric diseases. The major rehabilitation needs focused on medical service, assistive apparatus support and functional trainings. Conclusions The rehabilitation needs were different among different categories of disabled persons. Rehabilitation services should be provided accordingly.

Increasing evidence suggests that epigenetic dysfunction may influence the stability of normal pregnancy.The ten-eleven translocation (TET) family and 5-hydroxymethylcytosine (5-hmC) were found to be linked with epigenetic reprogramming.The present study aimed to examine the expression of the TET family and 5-hmC in the villi of human embryos and compared their expression between normal pregnancy and early pregnancy loss (EPL).Embryonic villi were collected from normal pregnant women (control) experiencing medical abortion and from EPL patients at gestation ages of 6,7 and 8 weeks.The mRNAs of TET family were analysed using quantitative polymerase chain reaction (qPCR),and TET proteins using Western blotting and immunohistochemical analysis.The MethylFlashTM Kit was used to quantify the absolute amount of 5-methylcytosine (5-mC) and 5-hmC.Our results showed that the expression of the TETs and 5-hmC in the normal villus decreased with increasing gestational age.Immunohistochemistry revealed that the TET proteins were expressed in the cytoplasm of trophoblasts and their expression was the highest in the 6-week tissue samples,which was consistent with the qPCR and Western blot results.The expression of TET1,TET2,and TET3 was lower in the villi in EPL group than in normal pregnancy group (P＜0.05 for all).It was concluded that the TET family and 5-hmC are critical in epigenetic reprogramming of human embryo.The findings also suggest that a deficiency of TETs in the villus might be associated with human EPL.
