Objective To assess the public health service quality objectively in Shenzhen,and promote the equity of basic public health services.Methods The criterion and method of the assessment were established by municipal health administrative department,the assessment of institutions and regions were conducted by experts selected by municipal professional institutions.Regional assessment was the comprehensive evaluation of public health service qualities of professional public health institutions,medical institutions and the community health centers.The assessment of the degree of public health service quality satisfaction was accomplished by a third-party institution.Results The accomplishment ratio of indicators for public health service quality was 93.2％.This ratio has witnessed a high increase with mental health institutions,occupational disease prevention and control institutions and health education institutions on one hand.On the other,it has dropped with institutions of disease control,chronic disease control and medical institutions within the region.On the whole,this ratio has increased with all the districts to different extents.Despite the overall improvement of public health capabilities citywide,imbalances are found among districts and institutions as well.Conclusion It is imperative to further improve the public health service system and equity while carrying out specific tasks in this respect.

Overall enhancement of the public health system ranks a key task and goal for the ongoing health reform.This paper described the public health development in Shenzhen amid the ongoing health reform.Shenzhen has achieved the following objectives as required in the reform:better public service by public health institutions,availability of major and primary public health services as required by the state and city,overall elevation of public health service capabilities,and significant drop of disease morbidity and mortality.Challenges ahead include room of improvement in public health service network,incentive mechanism of public health service providers,and that of public health service delivery capability.

Objective:To investigate the epidemiological characteristics and late diagnosis of suspected occupational diseases in Guangzhou from 2006 to 2018.Methods:The cases of suspected occupational diseases reported in Guangzhou from January 1, 2006 to December 31, 2018 were collected and followed up to the end of 2018. The cases of suspected occupational diseases were analyzed statistically.Results:A total of 1502 suspected occupational cases were reported in Guangzhou from 2006 to 2018, including suspected occupational otorhinolaryngological and oral diseases (58.59%, 880/1502) , suspected occupational chronic poisoning (25.03%, 376/1502) and suspected occupational pneumoconiosis (11.72%, 176/1502) . The key reporting areas were Huangpu District (27.50%, 413/1502) and Panyu District (20.91%, 314/1502) . The key reporting industries were manufacturing industry (80.36%, 1207/1502) , among which railway, ship, aerospace and other transportation equipment manufacturing industry (13.26%, 160/1207) , automobile manufacturing industry (12.51%, 151/1207) and general equipment manufacturing industry (10.19%, 123/1207) were the main industries. The main type of reported economy was private economy (39.95%, 600/1502) . The scale of the key reporting enterprises was medium and small-sized enterprises (31.09%, 467/1502 and 34.62%, 520/1502) . As of December 31, 2018, 263 cases were diagnosed with occupational diseases, and the diagnosis rate was 17.51%.Conclusion:The number of suspected occupational diseases reported in Guangzhou from 2006 to 2018 is large, and the overall diagnosis rate of suspected occupational diseases is low. It is necessary to strengthen the supervision and management of key diseases, key regions, and key industries of suspected occupational diseases. It is suggested that the reporting system of suspected occupational diseases should be standardized as soon as possible.

Objective To study the clinicopathologic features of pediatric vascular anomalies and application of ISSVA classification. Methods The clinical features, histopathologic findings and immunohistochemical results were analyzed in 117 cases of pediatric vascular anomalies encountered during the period from May 2014 to May 2015.Results A total of 117 cases of vascular anomalies were studied. The age of patients ranged from 18 hours after birth to 11 years ( mean age =34 months and median age =27 months) .There were 73 male patients and 44 female patients, with the male-to-female ratio being 1.7∶1.0.Congenital skin lesions were found in 37 cases ( 31.6%) .The common sites of involvement included head and neck region (46 cases, 39.3%), trunk (28 cases, 23.9%), extremities (14 cases, 12.0%) and internal viscera (31 cases, 26.5%).According to the new ISSVA classification, there were 74 cases of vascular malformations and 43 cases of vascular neoplasms ( ratio=1.7∶1.0 ) .The commonest vascular tumor encountered was infantile hemangioma ( 21 cases, 48.8%) , including 17 cases in proliferative phase and 4 cases in involutive phase.Thirteen cases (23.3%) of congenital hemangioma were found, with 8 cases of rapidly involuting congenital hemangioma and 5 cases of non-involutive congenital hemangioma.Three of the congenital hemangioma occurred in liver. There were 5 cases ( 11.6%) of pyogenic granuloma, 3 cases ( 7.0%) of tufted angioma and 1 case ( 2.3%) of Kaposiform hemangioendothelioma.Amongst the 74 cases of vascular malformations encountered, lymphatic malformation was found in 47 cases ( 63.5%) , venous malformation in 15 cases ( 20.2%) , lymphatic-venous malformation in 11 cases (14.9%) and arteriovenous malformation in 1 case (1.4%).All cases of vascular anomalies were all positive for CD31 on immunostaining.Glut1 and CD15 were positive both in proliferative and involutive phases of the 21 cases of infantile hemangioma, while other vascular tumors and vascular malformations were negative.Forty-seven cases of lymphatic malformation and 11 cases of lymphatic-venous malformation showed D2-40 expression.Focal positivity for D2-40 was demonstrated in 3 cases of tufted angioma and 1 case of Kaposiform hemangioendothelioma.Conclusions Vascular anomalies affecting infants and children include tumors and malformations. Accurate histopathologic diagnosis and ISSVA classification of the various types of vascular anomalies play an important role in clinical management.

BACKGROUNDThe prevalence of thyroid nodules (TN) is increasing rapidly. This study analyzed the epidemiological and clinical characteristics of TN in surgically treated patients and identified the risk factors for malignant nodules (MN) to provide more understanding of the differential diagnosis of TN.

METHODSA total of 6 304 TN cases who underwent thyroid surgery were included in this retrospective study. The clinical data were collected to evaluate the clinical and epidemiological characteristics and related risk factors for MN. The nature of TN (benign nodules (BN) or MN), medical records, laboratory data, and imaging data were analyzed. The risk factors for MN were screened using Spearman's rank correlation analysis and nonconditional binary Logistic regression analysis.

RESULTSThe number of surgically treated TN cases increased yearly. A total of 34.33% of cases were MN and 65.67% were BN. Up to 56.74% of these cases underwent unnecessary surgery. Among the MN cases, papillary thyroid carcinoma accounted for 94%, in which 46.71% coexisted with benign thyroid disease and 32.28% with multiple foci. Single-related factor analysis showed that age, employment, disease duration, history of breast nodules and/or hypertension, the levels of serum thyroid-stimulating hormone (TSH), thyroglobulin antibody (TgAb), and thyroid peroxidase antibody (TPoAb), and ultrasound features of TN were related to MN. Stepwise nonconditional binary Logistic regression analysis showed that 13 factors may be the independent risk factors for MN, including <40 years old, previous history of breast nodules and/or hypertension, disease duration <1 month, employment, hypoechoic nodule, irregular nodules, nodule calcification, solid echo nodule, fuzzy boundary, rich blood flow within nodules, abnormal lymph nodes around the neck, nodule diameter <1 cm, and abnormally high TgAb.

CONCLUSIONSOur results demonstrate a rapid increase in surgically treated TN cases and ratio of MN and indicate unnecessary surgeries in some cases. This study also suggest that age, duration of thyroid disease, history of breast disease and/or hypertension, the levels of serum TSH, TgAb, and TPoAb, and ultrasound features of TN are related to MN, and some of these factors may be the risk factors for MN.
