Abstract
BACKGROUND Acute respiratory distress syndrome (ARDS) is injury of alveolar epithelial cells and capillary endothelial cells caused by various factors, including endogenous and exogenous lung factors, leading to diffuse pulmonary interstitial and alveolar edema, and acute respiratory failure. ARDS involves alveolar epithelial cells and pulmonary interstitial capillary endothelial cells. Circulating endothelial cells (CECs) are the only marker that directly reflects vascular endothelial injury in vivo. There have been few studies on the correlation between peripheral blood CECs and ARDS at home and abroad. The lungs are the organs with the highest capillary density and the most endothelial cells, thus, it is speculated that when ARDS occurs, CECs are stimulated and damaged, and released into the circulatory system.
AIM To explore the correlation between CEC level and severity of ARDS in patients postoperatively.
METHODS Blood samples were collected from all patients on day 2 (d2) and day 5 (d5) after surgery. The control group comprised 32 healthy volunteers. Number of CECs was measured by flow cytometry, and operation time was recorded. Changes in various indexes of patients were monitored, and diagnosis of ARDS was determined based on ARDS Berlin definition. We comprised d2 CECs in different groups, correlation between operation time and d2 CECs, ARDS of different severity by d2 CECs, and predictive value of d2 CECs for ARDS in postoperative patients.
RESULTS The number of d2 CECs in the ARDS group was significantly higher than that in the healthy control group (P < 0.001). The number of d2 CECs in the ARDS group was significantly higher than that in the non-ARDS group (P < 0.001). The number of d2 CECs in the non-ARDS group was significantly higher than that in the healthy control group (P < 0.001). Operation time was positively correlated with number of CECs on d2 (rs = 0.302, P = 0.001). The number of d2 CECs in the deceased group was significantly higher than that in the improved group (P < 0.001). There was no significant difference in number of d2 CECs between patients with mild and moderate ARDS. The number of d2 CECs in patients with severe ARDS was significantly higher than that in patients with mild and moderate ARDS (P = 0.041, P = 0.037). There was no significant difference in number of d5 and d2 CECs in the non-ARDS group after admission to intensive care. The number of d5 CECs was higher than the number of d2 CECs in the ARDS improved group (P < 0.001). The number of d5 CECs was higher than the number of d2 CECs in the ARDS deceased group (P = 0.002). If the number of CECs was > 1351/mL, sensitivity and specificity of predicting ARDS were 80.8% and 78.1%, respectively.
CONCLUSION Changes in number of CECs might predict occurrence and adverse outcome of ARDS after surgery, and higher numbers of CECs indicate worse prognosis of ARDS.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

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.
