Objective: To analyze the direct economic burden caused by measles cases in Shanghai from 2017 to 2019 and its influencing factors. Methods: A total of 161 laboratory-confirmed measles cases reported from January 1, 2017, to December 31, 2019, in Shanghai were included in the study through the "Measles Surveillance Information Reporting and Management System" of the "China Disease Surveillance Information Reporting and Management System". Through telephone follow-up and consulting hospital data, the basic information of population, medical treatment situation, medical treatment costs and other information were collected, and the direct economic burden of cases was calculated, including registration fees, examination fees, hospitalization fees, medical fees and other disease treatment expenses, as well as transportation and other expenses of cases. The multiple linear regression model was used to analyze the main influencing factors of the direct economic burden. Results: The age of 161 measles cases M (Q1, Q3) was 28.21 (13.33, 37.00) years. Male cases (56.52%) were more than female cases (43.48%). The largest number of cases was≥18 years old (70.81%). The total direct economic burden of 161 measles cases was 540 851.14 yuan, and the per capita direct economic burden was 3 359.32 yuan. The direct economic burden M (Q1, Q3) was 873.00 (245.01, 4 014.79) yuan per person. The results of multiple linear regression model analysis showed that compared with other and unknown occupations, central areas and non-hospitalized cases, the direct economic burden of measles cases was higher in scattered children, childcare children, students, and cadre staff in the occupational distribution, suburban areas and hospitalized, with the coefficient of β (95%CI) values of 0.388 (0.150-0.627), 0.297 (0.025-0.569), 0.327 (0.148-0.506) and 1.031 (0.853-1.209), respectively (all P values<0.05). Conclusion: The direct economic burden of some measles cases in Shanghai is relatively high. Occupation, area of residence and hospitalization are the main factors influencing the direct economic burden of measles cases.

Clinical features of acute macular neuroretinopathy induced by Omicron / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the clinical features of acute macular neuroretinopathy(AMN)induced by Omicron.METHODS: A retrospective study. A total of 9 patients(18 eyes)diagnosed with AMN from December 2022 to January 2023 in the Hospital of Chengdu University of Traditional Chinese Medicine were included. Patients underwent spectral-domain optical coherence tomography(SD-OCT), fundus fluorescein angiography(FFA), fundus photography, autofluorescence(AF), infrared reflectance(IR), optical coherence tomography angiography(OCTA)and multicolor, etc. Furthermore, they were followed up for 1～3mo and observed the prognosis.RESULTS: The initial symptom of the Omicron-induced AMN was the sudden onset of central/paracentral scotoma in the eyes with or without impaired vision and metamorphopsia, and the scotoma could persist for at least 3mo. The image features of AMN are as follows. First, the SD-OCT examination showed the rupture of outer retinal layers, scattered hyperreflective lesions, and atrophy of outer retinal layers. In severe cases, hyperreflective lesions were seen in the inner nuclear layer(INL)or with microcystic cavities under the retinal pigment epithelium(RPE). Second, the OCTA examination demonstrated the decreased blood flow density of the deep capillary plexus(DCP)of the macula. Third, the IR examination showed the weak reflection of lesion areas. Fourth, the fundus photography demonstrated the localized brown wedge-shaped lesion.CONCLUSIONS: The Omicron-induced AMN is mostly found in young females, and the characteristic manifestation of fundus is damage to the outer retinal layers. The extent of fundus lesions is related to the systemic inflammatory response and ocular microcirculatory changes after infection. The multimodal fundus image examination and a history of Omicron infection are helpful to diagnose the Omicron-induced AMN.

Overview on diagnosis and treatment of oral diseases in the Qing Royal Court / 中华口腔医学杂志

The remained documents and archives show that the history of diagnosis and treatment of oral diseases in royal court of the Qing Dynasty was over 200 years. The departmental system of medical care in the Qing Royal Court was inherited from former Ming Dynasty. Although the departments in the system changed over reigns, the Department of Dentistry exist all the time. In a set of historical records of 38 medical cases opened to the public, the documented symptoms and diseases, in the sense of modern medical science, included periodontitis, oral mucosal diseases, dental caries, parotiditis, etc., and the patients involved various ranks in the court, showing that oral diseases were common in the Qing Royal Court. The royal doctors ranked variedly and the medication they used was diverse. Medical fuming or steaming and medical heating were some distinctive methods among the treatments. In 1600s, the western modern medical science started to be introduced into China. In the reign of Kangxi Emperor (1700s), many western doctors were employed by the royal court and they engaged in the treatment of oral diseases. The late Qing Dynasty appeared the second peak that western doctors came into China. In 1898, Dr. Jingrong Chen, a dentist who possessed knowledge of modern dentistry in Beijing city, set up a dental clinic in the royal court and gave treatment to patients in the royal members and high-ranking officials.

Enlightment of routine vaccination under the prevention and control of COVID-19 based on the circulating event of type Ⅲ vaccine-derived poliovirus in Shanghai / 中华预防医学杂志

Since the Global Polio Eradication Initiative was launched by the World Health Assembly in 1988, significant progress has been made in global polio prevention and control. But the occurrence of vaccine-associated paralytic poliomyelitis cases and vaccine-derived poliovirus related cases have become a major challenge during the post-polio era. While coronavirus disease 2019(COVID-19) has brought serious disease burden and economic burden to all countries in the world, prevention and control of vaccine-preventable infectious diseases such as polio should not be neglected under the background of the global common fight against COVID-19. Taking the type Ⅲ VDPV cycle event in Shanghai as an example, the paper discussed how to do a good job of routine inoculation under the prevention and control of COVID-19 to strictly prevent the outbreak of vaccine-preventable infectious diseases.

Mechanism of Huangqi Guizhi Wuwu Decoction in treatment of rheumatoid arthritis based on UPLC-LTQ-Orbitrap-MS, network pharmacology, and cell experiment / 中国中药杂志

In this study, ultra-high performance liquid chromatography-linear ion trap/electrostatic field orbit trap combined-type mass spectrometry(UPLC-LTQ-Orbitrap-MS) was used to analyze the main active components of Huangqi Guizhi Wuwu Decoction(HQGZ). A total of 50 active components were identified from HQGZ and 108 potential targets of the components related to the treatment of rheumatoid arthritis were retrieved based on network pharmacology, including 87 key targets, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the targets. The result indicated that HQGZ may exert therapeutic effects mainly through the sphingolipid signaling pathway, tumor necrosis factor(TNF) signaling pathway, as well as the positive regulation of ribonucleic acid(RNA) polymerase Ⅱ promoter transcription, inflammatory response and other biological processes. At the same time, cell experiment was performed to verify the key proteins in the TNF signaling pathway. The results demonstrated that HQGZ significantly reduced the expression of caspase-3(CASP3), TNF, relaxed(RELA) protein, and IkappaB kinase beta(IKBKB) in fibroblast-like synoviocytes induced by TNF-α. The results of UPLC-LTQ-Orbitrap-MS, network pharmacology and cell experiment showed that the active components in HQGZ may inhibit inflammatory response and regulate immune function and cell apoptosis by modulating key proteins in TNF signaling pathway to treat rheumatoid arthritis.

Comparison of the effects of different growth standards on infants in Urban Shanghai: a cluster-randomized controlled trial / 中华医学杂志(英文版)

BACKGROUND@#The Shanghai growth standards are higher than World Health Organization (WHO) growth standards, which may influence the feeding practices of the caregivers and increase the risk of overweight in these infants. This study aimed to compare the effects of different growth standards on childhood obesity in Shanghai metropolitan area.@*METHODS@#This was a cluster-randomized controlled trial conducted in 2 downtown areas with 19 community health service centers in Shanghai from November 2013 to December 2015. Randomization was done at the level of the community. Infants (health newborns) were assessed and monitored by the Shanghai growth standards (S-group) and the 2006 WHO growth standards (W-group), respectively. Measurements were taken at 1.0, 2.0, 4.0, 6.0, 9.0 and 12.0 months of age during follow-up period. Based on the values of length and weight measurements, according to the group's growth standards, doctors provided the caregivers with corresponding clinical consultation. Changes in weight-for-age z-score (WAZ), length-for-age z-score (LAZ), and weight-for length z-score (WLZ) between 2 groups were assessed using mixed regression models. Overweight was compared between 2 group at all follow-up measurements.@*RESULTS@#A total of 6509 infants (52.1% were boys) were in the W-group, and 8510 infants (51.4% were boys) were in the S-group. The overweight ratios between two groups were distinct at 9 months of age (3.4% in W-group and 4.3% in S-group) and 12 months of age (2.2% in W-group and 3.8% in S-group), and the differences were statistically significant (P = 0.020 and P < 0.001, respectively). Compared to W-group, the increase in WAZ (coefficient = 0.04, P = 0.004) and WLZ (coefficient = 0.09, P < 0.001) were significantly greater, and the LAZ was lower (coefficient = -0.04, P = 0.047) in S-group (W-group values were used as reference in mixed regression models).@*CONCLUSION@#Compared to the Shanghai growth standards, the adoption of WHO 2006 growth standards would reduce the risk of infant overweight in Shanghai metropolitan area up to 1 year of age.@*TRIAL REGISTRATION NUMBER@#ChiCTR1800015371, http://www.chictr.org.cn/ Chinese Clinical Trial Registry.

Characteristics of mandible and mandibular dentition according to vertical facial skeletal features of adolescents / 华西口腔医学杂志

OBJECTIVE@#We aim to examine teenagers with varying vertical facial skeletal types with near-normal occlusion. We further aim to identify and study mandibular morphology and dentition characteristics to establish normal ranges and variations for future clinical reference.@*METHODS@#According to the results of the case studies, 42 adolescents with near-normal occlusion were divided into three groups, namely, low- (7 cases), average- (23 cases) and high-angle (12 cases) groups. We used Invivo 5 software for Digital Imaging and Communications in Medicine (DICOM) data to calculate the cant of occlusal plane, axis corner of L6, ∠L1/MP, ∠L6/MP, Balkwill angle and Bonwill triangle of each group.@*RESULTS@#Markedly, the finding shows that the cant of occlusal plane and axis corner of L6 in the low-angle group were smaller than those of the other two groups. In the average-angle group, ∠L1/MP was larger than that of the high-angle group. Lastly, in the high-angle group, ∠L6/MP was smaller than those of the two other groups. On the one hand, these differences were considered statistically significant (P0.05).@*CONCLUSIONS@#In the low-angle group, the parallelisation of the occlusal plane tends to be more obvious compared with the two other groups. In the coronal section of the low-angle group, the axis of the mandibular first molar is up-right, whereas it is distally tilted in the sagittal section of the high-angle group. Furthermore, a number of differences are noted in the adult groups. Factors, such as aging and development in the craniofacial region, lead to changes in functional occlusion.

Objective@#To evaluate the efficacy and safety of drug-coated balloons (DCB) for de novo large coronary vessels.@*Methods@#One hundred and two patients were retrospectively enrolled in this study, there were 104 lesions with the reference lumen diameter of target vessel more than 2.8 mm and patients were treated with DCB in de novo lesions during May 2015 and July 2017 in our center. Coronary artery angiography and quantitative coronary angiography were performed in 82 (80.4%) patients at follow up period ((8.1±1.7) months post procedure). The endpoints were late lumen loss (LLL) at follow up,and major adverse cardiac events (MACE) including cardiac death, myocardial infarction (MI), target lesion revascularization (TLR) and stent or target lesion thrombosis at 12 months post procedure.@*Results@#Ninety-eight lesions were treated with DCB only, 6 (5.9%) bailout drug-eluting stent (DES) were used because of severe coronary dissection, 2 patients (2.0%) received revascularization driven by acute ischemic events during hospitalization. Cutting balloons and NSE balloons were used in 65.4% (68/104) and 26.0% (27/104) lesions. The lesion length was (12.57±3.58) mm and the DCB length was (19.87±4.55) mm. The late lumen loss was (0.01±0.52) mm during angiographic follow up. The TLR rate and overall MACE rate was 3.9% (4/102) and 3.9% (4/102) and there was no death,MI and target lesion thrombosis at 12 months follow up.@*Conclusion@#DCB treatment for de novo large coronary vessels is effective and safe.
