RESUMO

Objective: To evaluate the effect of clinic standardized blood pressure measurement model (SBPM) applying to first blood pressure measurement among community population aged 35 years old and above. Methods: SBPM was implemented in the community health service center of Dapuqiao street, Huangpu district of Shanghai from June 1, 2018, and the data between June 1 and December 31, 2018 was used as the SBPM data. The first-diagnosis blood pressure measurement data in this center between June 1 and December 31, 2017 was used as the conventional measurement (CM) model data. The detection rate of elevated blood pressure under SBPM was standardized according to the gender and age distribution of subjects in CM. The equilibrium of the value distribution of the end digit of blood pressure value in different pressure-measuring models and difference of elevated blood pressure rate of subjects with different characteristics and seasons were analyzed by using the χ(2) test, and the difference of standardized elevated blood pressure rate in different pressure-measuring models was analyzed by using the U test. Results: The SBPM included 1 548 subjects and 639 (41.28%) of them were males. The CM included 2 952 inpatients and 1 196 (40.51%) of them were males. The frequency of the end digit of blood pressure in SBPM ranged from 9.04% to 10.72%, and both systolic and diastolic blood pressure showed a balanced distribution of end digit (P values were 0.996 and 0.981 respectively). The frequency of blood pressure end digital in the CM ranged from 0.37% to 67.92%, and both systolic and diastolic blood pressure showed an unbalanced distribution (both P values <0.001). The crude rate and standardized elevated blood pressure rate in SBPM were 23.19% (359/1 548) and 23.05%, which were higher than that in CM, about 7.22% (213/2 952) (both P values <0.001). The elevated blood pressure rate in SBPM in summer, autumn and winter was 18.85% (141/748), 26.72% (152/591) and 31.58% (66/209), respectively, which was higher than that in CM, about 6.28% (91/1 450), 7.20% (82/1 139) and 11.02% (40/363), respectively (all P values <0.001). Conclusion: The quality of blood pressure data and the efficiency of hypertension screening of SBPM are better than those of CM when applying to first blood pressure measurement among community population aged 35 years old and above.

RESUMO

Objective: To analyze the effect of influenza vaccination intervention among key populations of chronic disease management in communities of Shanghai. Methods: A total of 50 787 patients aged ≥60 with diabetes, hypertension and chronic obstructive pulmonary disease (COPD) in Huangpu, Yangpu, Baoshan and Qingpu districts of Shanghai from January 2013 to August 2017 were selected as the intervention group, and 52 268 people from key populations with chronic disease management in Xuhui, Hongkou, Jiading and Fengxian districts were selected as the control group according to the geographical location and economic level. The intervention group accepted follow-up and health education of influenza vaccination via chronic disease outpatient based on information system. The implementation time of the intervention was from September 2017 to January 2018. The basic information and diagnosis information of two groups, and intervention completion of the intervention group were obtained from Shanghai chronic disease management information system and hospital record system. Results: The age of the intervention group and the control group were (76.76±8.33) and (77.97±8.51) years old, respectively (P<0.001); and there were statistical differences in gender, occupational and influenza vaccination rate between the two groups (P<0.001). A total of 28 644 (56.40%) subjects of the intervention group received intervention. There was no significant difference in age composition between finished and unfinished intervention groups (P=0.095), and there was significant difference in gender composition (P=0.044). Before the intervention, the vaccination rate of the intervention group was 0.75% (382 subjects) which was lower than that of the control group with 1.02% (533 subjects) (χ(2)=20.96, P<0.001). After the intervention, the vaccination rate of the intervention group was 1.73% (496 subjects) which was higher than that of the control group with 1.42% (744 subjects) (χ(2)=11.65, P=0.001). Subjects that were male, younger, uptake of influenza vaccine before the intervention, received intervention and professional and technical personnel were more likely to take influenza vaccine, with OR (95%CI) 1.29 (1.13-1.47), 0.97 (0.96-0.98), 260.30 (215.21-314.83), 1.85 (1.61-2.11) and 1.48 (1.10-1.99), respectively. Conclusion: Influenza vaccination intervetion raised the vaccination rate of key population of chronic disease management. Male, younger, those who had been vaccinated before the intervention, who received the intervention, and professional and technical personnel were more likely to be vaccinated.

RESUMO

OBJECTIVE: The aim of this study was to investigate the expression of micro ribonucleic acid-411-5P (miR-411-5p) in non-small cell lung cancer (NSCLC), and to explore the effect of miR-411-5p on the biological behavior of NSCLC cells as well as the underlying molecular mechanism. PATIENTS AND METHODS: Quantitative Real Time- Polymerase Chain Reaction (qRT-PCR) was used to detect the expression level of miR-411-5p in NSCLC tissues and cells. MiR-411-5p mimics and relevant controls were transfected into NSCLC cells according to the instructions of Lipidosome 2000. Transfected cells were divided into the experimental group and the control group. The transfection efficiency of each group was detected by qRT-PCR. After miR-411-5p overexpression, methyl thiazolyl tetrazolium (MTT) assay, flow cytometry, and transwell assay were used to detect the biological changes of cells in each group. Bioinformatics predicted that pumilio homolog 1 (PUM1) was the target gene of miR-411-5p. Subsequently, the mRNA and protein expression level of PUM1 in each group was detected by qRT-PCR and Western blotting, respectively. Dual-luciferase reporter assay was used to validate the target regulatory relationship between miR-411-5p and PUM1. RESULTS: The results of qRT-PCR showed that miR-411-5p was relatively lowly expressed in NSCLC tissues and cells. After miR-411-5p overexpression, MTT results revealed that the proliferation of NSCLC cells was decreased. Flow cytometry results indicated that the apoptosis rate of NSCLC cells was increased, and cell cycle was arrested in the G0-G1 phase. Meanwhile, the transwell assay demonstrated that the migration and invasion abilities of NSCLC cells were decreased. Bioinformatics predicted that PUM1 was the target gene of miR-411-5p. After miR-411-4p was overexpressed in NSCLC cells, qRT-PCR and Western blotting showed that both the mRNA and protein expression levels of PUM1 were up-regulated. Moreover, dual-luciferase reporter assay demonstrated that miR-411-5p could significantly inhibit the luciferase activity of wild-type PUM1-3'-untranslated region (3'-UTR). However, it exhibited no effect on the luciferase activity of cells transfected with mutant plasmids. CONCLUSIONS: MiR-411-5p may be involved in regulating the biological function of NSCLC cells via targeting PUM1. In addition, miR-411-5p may serve as a potential target for the molecular therapy of NSCLC.

RESUMO

OBJECTIVE: With the help of new technologies like 64-slice spiral CT, including latest AW4.4, 2D nodule comparing and analyzing technology, MPR and 3D technology, MIP technology and the technology of analyzing pulmonary vascular density by the method of perfusion scanning, we performed characteristic analysis of ground-glass opacities (GGO) for the early diagnosis of lung cancer. PATIENTS AND METHODS: We selected 62 patients suspected of lung cancer, whose conventional CT showed that they were patients with GGO. With the help of the new technologies of 64-slice spiral CT provided by GE Company, prospective scans were made and 2 to 4 times of review were arranged. After that, the patients were treated with surgery or needle biopsy to get lesion's pathological results. After several scans, the results including lesion's form, density, blood supply, peripheral sign, doubling time and tissue perfusion were drawn to make a comparison. Based on the results, comparative analysis on GGO's characteristics was made from morphological and functional perspectives. RESULTS: 41 patients (66.1%) were pathologically diagnosed with cancer, 10 were diagnosed with inflammation, 7 with fibrosis, and 4 with edema, hemorrhage and other lesions. The comparisons were made between the tumor groups' clinical manifestations (sex, age, symptoms including smoking, coughing, and expectoration), and the difference had no statistical significance (p>0.05). Conventional CT scan showed that the shape of GGO was irregular and it showed spiculated sign and pleural indentation. The proportion of the patients with vessel convergence in the tumor group was significantly higher than that of the non-tumor group (p<0.05). However, the comparisons between lesions' number, location (superior lobe of the right lung), diameter, edge (blur) and lobulation were made to get a difference ratio (p>0.05) which had no statistical significance. Tumor group's doubling time was significantly short, and its perfusion parameters including BF, BV, MTT, and PS were increased significantly (p<0.05). CONCLUSIONS: The new 64-slice CT technology has great value in the diagnosis of the tumorous GGO.

RESUMO

Objective:To analyze the complications of adenotonsilectomy assisted with coblation in children. Method:Complications of 2 089 cases of children with adenoid and tonsil surgery assisted with coblation, in our hospital nearly 10 years, were analyzed by epidemiological methods through the method of retrospective analysis. Result:①the sex ratio of male to female was 2.08:1, average age (5.87±3.12) years old, and most of 2 089 cases 76.35% (1 595/2 089) were 3-7 years old; ②all cases underwent adenoidectomy. Different surgery methods of tonsil consisted of three groups as partial resection associated with ablation was 69.17% (1 445/2 089), ablation (channeling) alone was 22.26% (465/2 089) and total resection was 8.57% (179/208). The amount of bleeding in operation was (8.52±3.18)ml, average operation time was (30.15±8.26) minutes, the postoperative pain score was (3.77±1.61); ③The incidence of postoperative complications: postoperative bleeding (all were secondary bleeding cases) rate was 0.24% (5/2 089), recurrence rate was 0.14% (3/2 089), prevertebral lymphadenitis was 0.96% (20/2 089), the other was 0.29% (torus hyperplasia in 2 cases, dyspnea in 2 cases, 1 cases of angle of mouth burned, nasopharyngeal adhesion in 1 cases). Postoperative fever rate was 9.81% (205/2 089). Conclusion:coblation technique is a good method for the treatment of children's adenoids and tonsil diseases with high efficiency and low complications. But improving the operation procedure proficiency level and skills of operation is an important link to reduce complications.

RESUMO

BACKGROUND: The Epstein-Barr virus (EBV) is thought to be involved in the pathogenesis of some Hodgkin disease (HD) cases. EBV may be associated particularly with childhood HD, a disease rare in the West compared with developing countries. In this study, a large series of Chinese pediatric HD cases has been examined to determine the age-specific prevalence of EBV. METHODS: Paraffin sections from 104 pediatric and 52 adult Chinese HD cases were examined for EBV-RNA (EBERs) and EBV latent membrane protein-1. RESULTS: Most pediatric cases arose in boys and showed an histology of mixed cellularity. Prominent interfollicular involvement was seen frequently in the childhood cases. EBV was identified in tumor cells in 113 of 156 (72%) HD cases but was more frequent in pediatric cases (93 of 104; 89%) compared with adult cases (20 of 52; 38%) (P < 0.01; chi-square test). EBV was found in 86 out of 91 (95%) cases in children aged 3-10 years and in 7 out of 13 (54%) cases in children aged 11-14 years (P < 0.01; chi-square test). The virus was less frequent in cases in young adults than in old adults, although this trend was not significant (P > 0.05; chi-square test). Pediatric HD was associated with EBV irrespective of histologic subtype. In adults, EBV was associated more frequently with mixed cellularity than with other subtypes. CONCLUSION: To the authors' knowledge, this is to date the largest series of pediatric HD cases studied for EBV. Study findings provided further evidence that HD is etiologically heterogeneous. The authors believe that pediatric HD now should be regarded as a distinctive EBV-related lymphoma.

RESUMO

Epstein--Barr virus (EBV) is associated with several malignancies. Specific EBV gene variants, e.g. the BamHI f configuration, a C-terminal region 30 bp deletion in the latent membrane protein-1 (LMP1) gene (del-LMP) and the loss of an XhoI site in LMP1 (XhoI-loss), are found in Chinese cases of nasopharyngeal carcinoma (NPC), suggesting that EBV sequence variation may be involved in oncogenesis. In order to understand better the epidemiology of these EBV variants, they were studied in virus isolates from EBV-positive Chinese cases of Hodgkin's disease (HD; n=71) and donor throat washings from healthy CHINESE: Sequencing was performed of 15 representative EBV isolates, including the first analysis of the LMP1 promoter in Asian wild-type EBV isolates. The following observations were made. (i) Three EBV LMP1 variants were identified, designated Chinese groups (CG) 1--3. In both EBV-associated HD and in healthy Chinese, CG1-like viruses showing del-LMP1 and XhoI-loss were predominant. (ii) CG1viruses were distinct from European and African variants, suggesting that this profile is useful for epidemiological studies. (iii) Specific patterns of mutations were present in the LMP1 promoter in both CG1 and CG2. (iv) The BamHI f variant was not found in Chinese HD, in contrast to Chinese NPC and European HD. This study confirms that EBV isolates in Chinese HD and other tumours differ from those reported in Western cases. However, this reflects the predominant virus strain present in the healthy Chinese population, suggesting that these are geographically restricted polymorphisms rather than tumour-specific strains.

RESUMO

To investigate the relationship between IUD-induced menorrhagia and spiral arteriolar function, we examined the endometrium under light and electron microscope on samples obtained within 24 hours after the onset of premenstrual spotting. These samples included an IUD bleeding group (20 cases), an IUD non-bleeding group (20 cases) and an IUD non-user group (10 cases) as controls. Compared with the IUD non-user group the degenerative changes of spiral arteriolar wall were more severe and dilation of the spiral arteriolar lumen was more obvious, especially in the spongeous layer. In the IUD non-user group these changes were mild, suggesting that IUD-induced menorrhagia might be correlated with poor contractility of spiral arterioles in the spongeous layer.

RESUMO

Forty-two cases of Chinese T-cell lymphoma were studied for expression of Epstein-Barr virus (EBV) encoded RNA (EBER-1) and EBV latent membrane protein-1 (LMP-1) using in situ hybridization and immunohistochemistry, respectively. EBV was detected in tumour cells in 24/39 peripheral T-cell lymphomas (62%), comprising 18/27 pleomorphic, medium and large cell lymphomas (67%), 4/6 angioimmunoblastic lymphadenopathy-like lymphomas (67%), 2/2 Lennert's lymphomas, 0/2 anaplastic large cell lymphomas, and 0/2 T-zone lymphomas. EBV was not found in three T-lymphoblastic lymphomas. EBV was associated with 12/24 nodal (50%) compared with 12/15 extranodal (80%) peripheral T-cell lymphomas. In EBV positive nodal lymphomas, 9/12 cases (75%) contained less than 10% EBER positive tumour cells. In EBV positive extranodal lymphomas, 9/11 cases (82%) showed EBV gene expression in more than 50% of the tumour cells, and in five of these almost all tumour cells were positive. Lymphomas of the nasopharynx (mainly midline granuloma-type) showed EBER-1 expression in nearly all tumour cells. LMP-1 was detected in 19/23 EBER positive peripheral T-cell lymphomas (83%). Our results show that EBV is strongly associated with peripheral T-cell lymphomas in Chinese. An important role for the virus is suggested in lymphomas of the nasopharynx. The significance of EBV in T-cell lymphomas that contain only a minor population of virally infected tumour cells is currently unclear.

RESUMO

In this study, 6 patients were randomly divided into three groups, receiving different intestinal preparations. Colonic mucosa were biopsied for S-520 scanning electron microscopy. Of them, only a tiny minority of bacteria were found in the specimen of the first group. Bacteria weren't discovered in the other two groups. Therefore, three conventional enteric preparations are equally effective and efficient in eliminating intestinal flora. The causes of postoperative incisional infection are many and varied.

RESUMO

Epstein-Barr virus (EBV) can be detected in Hodgkin and Reed-Sternberg (HRS) cells in about one-half of cases of Hodgkin's disease (HD) in Western countries. To determine whether EBV is also associated with HD in a developing country such as China, we studied paraffin sections from 28 Chinese cases of HD for expression of latent membrane protein-I (LMP-I) and EBV-encoded small RNA (EBER-I), using immuno-histology and RNA/RNA in situ hybridization respectively. The cases were selected from a large series of Chinese lymphomas following histological and immunophenotypical revision. EBV gene expression was found in HRS cells in 17/28 cases, and was related to histological sub-type, being present in 10/11 of mixed cellularity, 6/14 nodular sclerosis, 0/1 lymphocytic predominance, 0/1 lymphocytic depletion, and 1/1 unclassified HD. The 2 methods for detecting EBV gene expression gave similar results, except in one case of nodular sclerosis, in which HRS cells were negative for EBER-I, but weakly positive for LMP-I. In 5/12 cases with EBER-negative HRS cells, rare small or medium-sized lymphocytes expressed EBER-I but not LMP-I. These results suggest that (i) Chinese HD is frequently associated with EBV; (ii) the proportional frequency and sub-type distribution of EBV-positive HD are similar in China and in the West; (iii) both LMP-I immunohistology and EBER in situ hybridization reliably detect EBV in HRS cells in routine biopsies, but the former is simpler and less resource-consuming to perform.

RESUMO

Hematopathologists sometimes rely upon the "monoclonality" of immunoglobulin light chains of B-cells as an indicator of malignancy in lymph node biopsies. The validity of using the ratio of kappa to lambda light chains for defining monoclonality has not been statistically established, however. We examined with flow cytometry 57 unequivocal B-cell lymphomas and 49 benign lymphoid hyperplasias. Our purpose was to define and study the optimal numerical criteria for discriminating between B-cell lymphomas and benign hyperplasia on the basis of the kappa:lambda ratio. The data indicate that ratios less than .7 or greater than 5.5 are the optimum for discriminating between lymphoma and benign hyperplasia, but they have a false negative rate of approximately 27% and a 6% false positive rate. The reasons for the relatively low sensitivity are discussed. We conclude that kappa:lambda ratios are a fairly specific but insensitive parameter for distinguishing between B-cell lymphoma and benign lymphoid hyperplasia.
