Objective To evaluate the impact of hypertension self-management on self efficacy of community residents.Methods November 2011 to February 2012,twenty-eight medium-sized and better adherence to community was selected from fourteen districts and counties in Beijing.In this community-based randomized controlled trial,323 hypertensive patients were randomly assigned to the treatment group (n =159,receiving hypertension self-management) and the control group (n=164,receiving standard hypertension management).A questionary survey was completed at baseline and 6 weeks.Rank sum test or Chi-square test was used for data analysis.Results The average age of the treatment group or the control group was (61.9 ±9.1) vs (61.8 ±9.0) years old,respectively.No significant difference in mean age,gender and education level was found between the two groups (F =0.164,x2 values were 0.782 and 2.093,respectively ; all P ＞ 0.05).In the treatment group,the scores of fatigue,headache and shortness of breath were declined (when compared with the controlled females,Z =-5.198,-3.873,-2.781 ; P ＜ 0.05).Self-efficacy score of the treatment group was increased after the intervention.Women's symptom management self-efficacy and common disease management self-efficacy were significantly higher (Z=-2.958,-2.582; P ＜ 0.05).In comparison with the control group,before and after self-management,the added scores of communication ability with doctors were increased.But the difference was not statistically significant (P ＞ 0.05).Conclusion Six-week self-management program may improve self efficacy among hypertensive patients.

3T3-L1 adipocytes were cultured with various concentrations of high-density lipoprotein ( HDL, 0, 10, 50, and 100 μg/ml ) for 16 h and with lipopolysaccharide ( LPS, 100 ng/ml ) for another 6 h. Interleukin-8 in the medium was determined by ELISA, and PPAR-γ mRNA expression by reverse transacription polymerase chain reaction (RT-PCR). Interleukin-8 levels were increased in LPS-treated cells ( P＜0.05 ), but decreased in HDL-treated cells in the dose-dependent manner. PPARγ mRNA expressions were increased in HDL-treated groups than those treated only with LPS. These results suggested HDL may decrease interleukin-8 secretion via up-regulating PPARγ expression in adipocytes.

Objective To investigate surgical opportunity and suitable treatment approach in nodular Hashimoto's disease.Methods An analysis was performed in 388 pathologically confirmed cases with nodular Hashimoto's disease and other thyroid-related diseases.All the cases were involved with surgical treatment due to thyroid nodules from June,1995 to Dec,2005.Results Among the above-mentioned cases,64 cases (16.5%) were Hashimoto's disease with the presence of thyroid cancer,190 (48.9%) nodular thyroid tumor,94 (24.2%) thyroid adenoma,7 (1.8%) hyperthyroidism,the rest (8.5%) simple Hashimoto's disease.Prior to 2000, among 106 cases of Hashimoto's disease there were 15 cases accompanied by thyroid cancer.Since 2001,282 cases of Hashimoto's disease were dealt surgically,49 of which had thyroid cancer.Compared to the period from 1995 to 2000,the complication of Hashimoto's disease and thyroid cancer has been sharply increasing during the recent five years (P

OBJECTIVETo observe the effect of Pinggan Qianyang Recipe (PQR) on inhibiting angiotensin II (Ang II) induced proliferation and migration of vascular smooth muscle cells (VSMCs) and changes of DNA methylation.

METHODSVSMCs were cultured using tissue explant method, and PQR containing serum was prepared. Primarily cultured VSMCs were divided into four groups, the normal group, the model group, the folate group (folic acid intervention) , and the PQR group. The proliferation and migration of VSMCs was duplicated by Ang II. After 24-h Ang II induced culture, 40 microg/mL folic acid was added to the folate group for 48 h, while 5% PQR containing serum was added to the PQR group for 48 h. The cell growth curve of VSMCs was drawn by using Cell Counting Kit (CCK-8). The proliferative activity of VSMC was determined by MTT assay. The migration of VSMCs was measured by Millicell chamber. The general level of cytosine methylation in cell nucleus was detected via 5-mC antibodies immunofluorescence, and mRNA expression levels of DNA methyltransferase 1 (DNMT1) were measured by Real-time q-polymerase chain reaction (q-PCR).

RESULTSVSMCs were promoted by Ang II at 10(-6) mol/L for 24 h. Compared with the normal group, the proliferative activity and migration quantity of VSMCs obviously increased, and DNA methylation level obviously decreased (P < 0.05, P < 0.01). Compared with the model group, the cell growth, proliferative activity and migration quantity of VSMCs obviously decreased and the general DNA methylation level increased in the folate group and the PQR group (P < 0.05, P < 0.01). Compared with the normal group, the mRNA expression of DNMT1 decreased in the model group (P < 0.01). Compared with the model group, mRNA expression of DNMT1 in Ang II induced VSMCs was obviously enhanced in the folate group and the PQR group (P < 0.01).

CONCLUSIONSPQR could inhibit Ang II induced proliferation and migration of VSMCs, and cause high genomic DNA methylation level. Changes of DNA methylation might be associated with DNMT1 expression.

Objective To investigate the characteristics and clinicopathologic significance of microlymphatic vessel in breast cancer.Methods The microlymphatic density(MLD)and lymphatic vessel invasion(LVI)in 102 cases of breast cancer tissue were evaluated by immunohistochemical staining,using monoclonal antibody for podo- planin.The characteristic of microlymphatic vessel and the relationship between MLD,LVI and clinicopathological parameters were evaluated.And blood vessels were also detected with CD34 by double-labeling immunohistochemis- try for confirming the specificity of podoplanin for microlymphatic vascular.Results Podoplanin antibody was spe- cific for lymphatic vessel without intersection with blood vessel.The density and morphology of microlymphatic ves- sel in breast cancer had significant heterogeneity.The MLD in breast cancer tissues was significantly higher than that in normal breast tissues.The microlymphatic vessel that in breast cancer tissues indicated by a more irregular shape and a larger open lumen,and some cancer embolus entering the open microlymphatic vessel could be seen. MLD was significantly correlated with LVI(P

Ischemic stroke is a primary cause of death and long-term disability all over the world. This disease is resulted from ischemia and hypoxia in brain tissues because of insufficient blood supply and causes a series of physiochemical metabolism disorders and physiological dysfunction. Its high disability ratio has bright huge burdens to society, governments and families. However, there is not efficacious medicine to treat it. In this study, a right middle cerebral artery occlusion was established in rats to observe the multi-path and multi-aspect intervention effects of Tibetan patent medicine Ruyi Zhenbao pills in reducing injuries to Nissl bodies, cerebral edema and inflammatory reactions and preventing cellular apoptosis, in order to lay a foundation for defining its therapeutic mechanism in acute ischemic stroke.

OBJECTIVETo screen for the differential protein peaks of renal cell carcinoma (RCC) using magnetic beads-based matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).

METHODSSerum proteins were profiled by magnetic beads (WCX) from 62 RCC patients and 37 patients with benign renal space-occupying lesions. Protein peaks were identified by MALDI-TOF-MS. Data were analyzed with Biomarker Wizard 3.1 and Biomarker Patterns Software 5.0. Diagnostic model for RCC was constructed based on 47 RCC cases and 26 patients with benign renal space-occupying lesions. The remaining 26 cases were evaluated with blind method.

RESULTSSeven differential protein peaks related to RCC were identified (Pβ0.05). The diagnostic model for RCC constructed by the differential protein peaks (m/z 2945.35, 15340.8, 6984.51, and 5819.23) generated excellent separation between the RCC and control groups, with a sensitivity of 83.0% and the specificity of 84.6%. As validated by blind method, the model had a sensitivity of 80.0% and a specificity of 81.8%.

CONCLUSIONDifferential protein peaks for RCC can be identified in serum by magnetic beads-based MALDI-TOF-MS, which is also valuable for the establishment of a RCC diagnostic model with a high sensitivity and specificity.

OBJECTIVETo investigate the method for creation of auriculocephalic sulcus.

METHODSThe reconstruction was performed 4-12 months after the first surgery. Skin incision was made 5mm posterior to the outer margin of the auricle. The ear framework was elevated with a thick fascia at the deep surface. The costal cartilage banked at the first operation was shaved and transplanted to the deep surface of the concha with sutures. The position and angle of the ear framework was adjusted to be familiar to the healthy ear. The auriculocephalic angle was slightly larger than that in the contralateral ear. Two flaps were designed at the upper and lower area of reconstructed ear and rotated to cover the cartilage. The wound at the donor site was closed with skin graft.

RESULTSA total of 72 patients were treated. All the flaps survived completely. 51 patients were followed up for 3-24 months with satisfactory results. The auriculocephalic sulcus maintained at about 20-30 degree.

CONCLUSIONSIt is a simple, safe and reliable method to create a auriculocephalic sulcus with two random skin flaps from mastoid area combined with skin graft.

OBJECTIVETo study the possible role of hTERT and c-myc in endometrial carcinogenesis.

METHODSThe expression of hTERT and c-myc mRNA was examined by in situ hybridization of endometrial samples from 14 cases with simple hyperplasia, 10 with complex hyperplasia, 8 with atypical hyperplasia and 42 with endometrioid carcinoma.

RESULTSExpression of hTERT was demonstrated in samples with simple hyperplasia, complex hyperplasia, atypical hyperplasia and carcinoma at frequencies of 2/14, 4/8, 8/10 and 39/42 (92.9%), respectively. The prevalence and intensity of the hTERT signal was greater in the carcinomas and lesions with atypical hyperplasia than those with simple or complex hyperplasia (P < 0.05). The expression of c-myc was demonstrated in samples with simple hyperplasia, complex hyperplasia, atypical hyperplasia and carcinoma at frequencies of 3/14, 1/8, 5/10 and 23/42 (54.8%), respectively. The frequency of c-myc expression was higher in carcinomas and hyperplastic lesions with atypia than those in lesions with simple or complex hyperplasia without atypia (P < 0.05). The expression of hTERT was shown to be correlated with the level of differentiation (P < 0.05), while the c-myc expression appeared to be associated with the depth of myometrial invasion (P < 0.05). The expression levels of hTERT and c-myc were not found to be correlated with each other in the tissues examined (P > 0.05).

CONCLUSIONSThe expression of hTERT and c-myc may be involved in the progression from the endometrial aypical hyperplasia to invasive carcinoma. The correlation between hTERT and c-myc in endometrial hyperplasia and carcinoma are not found.

Objective:To evaluate the clinical efficacy of Guizhi Mahuang Geban Decoction combined with conventional western medicine in the treatment of post infections cough (PIC), and to explore the mechanism.Methods:A total of 100 PIC patients in our hospital from January 2020 to July 2021 who met the inclusion criteria were divided into 2 groups according to the random number table method, with 50 in each group. The control group was treated with conventional western medicine, and the study group was treated with Guizhi Mahuang Geban Decoction and the treatment of the control group. Both groups were treated for 10 days. TCM symptom scores were performed before and after treatment. The levels of neurokinin A (NKA), substance P (SP), neurokinin B (NKB) and calcitonin gene related peptide (CGRP) were detected by ELISA. Adverse events were recorded and clinical effects were evaluated.Results:The total clinical effective rate was 90.0% (45/50) in the study group and 68.0% (34/50) in the control group, and there was significant difference between the two groups ( χ2=7.29, P=0.007). The scores of cough, expectoration, pharyngeal itch and total score in the study group were significantly lower than those in the control group ( t values were 8.04, 6.30, 9.03, 9.71, all Ps<0.01). After treatment, NKA [(86.08±18.21) ng/L vs. (137.68±28.29) ng/L, t=10.85], SP [(54.23±11.28) ng/L vs. (71.75±15.34) ng/L, t=6.51], NKB [(96.15±20.19) ng/L vs. (149.84±30.22) ng/L, t=10.45], CGRP [(62.93±18.35) ng/L vs. (89.59±23.25) ng/L, t=6.37] levels in the study group were significantly lower than those in the control group ( P<0.01). The incidence of adverse events was 8.0% (4/50) in the control group and 10.0% (5/50) in the study group, and there was no significant difference between the two groups ( χ2=0.13, P=0.727). Conclusions:Compared with western medicine alone, Guizhi Mahuang Geban Decoction combined with western medicine can rapidly improve patients' symptoms, improve curative effect and have better safety for PIC. Its mechanism may be related to the regulation of NKA, SP, NKB and CGRP levels.
