Objective To provide a reasonable clinical evidence and testing index for acute myocardial infarction (AMI) early diagnosis by investigating the levels of serum ischemia-modified album(IMA),cardiac troponin I(cTnI) and high-sensitivity C-reactive protein (hs-CRP) in patients with AMI.Methods 66 cases with AMI were divided into two groups by the time of starting attack chest pain to clinic,the time of 0-4h as E group (39 cases),4-8h as F group (27 cases),another 59 healthy persons in the control group were detected.Then collected serum samples from each case to detect the concentration of the IMA,cTnI and hs-CRP.Results The levels of serum IMA,cTnI and hs-CRP in E group were significantly higher than those in the control group( P ＜ 0.05 or P ＜ 0.001 ),in addition to the IMA level was higher than normal,cTnI and hs-CRP levels were in the normal range.The levels of serum IMA,cTnI and hs-CRP in F group were significantly higher than the levels of control group( P ＜0.05 ) and also above the normal.Conclusion IMA,cTnI and hs-CRP not only can be used as the effective index for AMI early diagnosis,but also help for early diagnosis.The results provide a reliable basis for disease treatment and condition development.

Objective Investigate the clinicopathological characteristics of h?rthle cell tumors of the thyroid. Methods Sixteen cases of HCT were studied by the clinicopathological study and immunohistochemical and review of the literature. Results There were 13 cases of h?rthle cell adenomas, 5 h?rthle cell follicular carcinomas. Immunostains showed that almost all benign and malignant HCT expressed TG, vimentin, S-100 protein. Conclusions HCT is a potential malignant tumor with a defined pathologic feature. It should be follow up for a longer time to their biological behaviors. To distinguish between the benign and the malignant depends on traditional encapsulation, and whether there is a blood vessel invasion or metastasis.

Objective To assess the correlation between tenosynovitis or rupture of the flexor hallucis longus (FHL) and pes planus in patients with rheumatoid arthritis (RA).Methods The data of 47 RA patients (97 feet) with painful feet was retrospectively analyzed which was collected From February 2008 to June 2011.In accordance with the results of the FHL changes got by ultrasonography,the patients were divided into 3 groups.Group A consisted of those with normal FHL (27 feet).Group B consisted of those with FHL tenosynovitis (40 feet),and Group C eonsisted of those with FHL rupture (27 feet).Load bearing lateral radiographs were taken for all the patients.The correlation study was carried out based on the pes planus-related parameters,such as the measurement of heel pitch angle (HPA) and tarsal and 1st metatarsal angle (TM1).Factors like patients' age and course of disease were also taken into the consideration during the study.Results The mean age of those in group A was 49.9±9.2 years vs.56.2±9.2 years in group B and 54.7±8.0 years in group C.The mean duration was 4.7±2.6 years in Group A vs.16.2±7.4 years in Group B 5°±3.6° in Group C.The mean TM1 was 2.5°±2.2° in Group A vs.6.5°±3.2° in Group B and 11.2°±4.9° in Group C.Significant statistics difference were found among the three groups in these parameters.HPA＜ 20° was found among 6/27 feet in group A,31/40 in group B and 27/27 in group C.TM1 ＞4° was found among 5/27 feet in group A,30/40 in group B and 27/27 in group C.Conclusion FHL changes were common in RA patients and its severitv had positive correlation to pes planus.These changes were affected by age and duration,and could be evaluated effectively by ultrasound.

Enterovirus 71 (EV71) is a neurotropic pathogen that can induce hand, foot and mouth disease in children. There is an appreciable mortality rate after EV71 infections. The mechanism of action of EV71 replication is not known. Recent work has identified some of cell factors of the host that participate in the synthesis of the RNA and proteins of EV71 (e.g., hnRNP K, reticulon 3 (RTN 3)). In that work, researchers used a competitive assay to show that hnRNP K can interact with EV71 5' UTR, which is required for efficient synthesis of viral RNA. Using a yeast two-hybrid system, other researchers demonstrated that RTN 3 interacts with the N-terminal domain of EV71 2C, which is crucial for replication of viral RNA. Here, we discuss recent work focusing on the molecular mechanisms of hnRNP K and RTN 3 in the synthesis of the RNA and proteins of EV71.

Objective : To investigate the fertility level of registered population in Baoshan District, Shanghai Municipality and the incidence of adverse birth outcomes of live births from 2013 to 2022, so as to provide the evidence for improving maternal and child health care strategies. Methods: The data pertaining to live births registered in Baoshan District from 2013 to 2022 were collected through the Shanghai Birth Medical Information System, including the basic information of live births and maternal fertility. The indicators such as fertility level, parity, birth age and incidence of adverse birth outcomes of live births were descriptively analyzed. The trend of crude birth rate and total fertility rate was analyzed by annual percent change (APC). Results: A total of 56 719 live births were registered in Baoshan District from 2013 to 2022. The crude birth rate was 6.54‰, the total fertility rate was 31.78‰, and the sex ratio at birth was 105.61. The crude birth rate showed a downward trend from 2016 to 2022 (APC=-11.054%, P<0.05), and the total fertility rate showed a downward trend from 2017 to 2022 (APC=-10.377%, P<0.05). The proportion of second parity and above showed an increasing trend from 2013 to 2017 (P<0.05) and a decreasing trend from 2017 to 2022 (P<0.05). The maternal childbearing age showed an increasing trend from 2013 to 2022 (P<0.05), the incidence of premature infants and low birth weight infants showed an increasing trend (both P<0.05). The incidence of premature infants and low birth weight infants increased with the rising childbearing age (both P<0.05). Conclusions The fertility level in Baoshan District was relatively low from 2013 to 2022. The proportion of second parity and above showed an upward trend followed by a downward trend. The incidence of premature infants and low birth weight infants increased with the rising childbearing age.

Objective: To analyze the results of colorectal cancer screening among residents in Baoshan District, Shanghai Municipality from 2013 to 2021, so as to provide the basis for promoting colorectal cancer screening and prevention. Methods: Permanent residents aged 50 to 74 years in Baoshan District from 2013 to 2021 were selected as the screening population. The initial screening was conducted using a risk assessment form and fecal occult blood test. Positive results on either the risk assessment form or fecal occult blood test were considered positive for the initial screening. Participants with positive initial screening results were invited to undergo colonoscopy. The positive rate of the initial screening, colonoscopy compliance rate, and colonoscopy results were analyzed. Results: A total of 264 907 individuals underwent the initial colorectal cancer screening in Baoshan District from 2013 to 2021, with 65 333 individuals (24.66%) testing positive. Among them, the positive rate of the risk assessment form was 12.16%, and the positive rate of fecal occult blood test was 14.64%. A total of 14 473 individuals completed colonoscopy, with a compliance rate of 22.15%. A total of 1 284 precancerous lesions were detected, with a detection rate of 8.87%, and 386 cases of colorectal cancer were identified, with a detection rate of 2.67%. The positive rate of the initial screening, colonoscopy compliance rate, precancerous lesion detection rate, and colorectal cancer detection rate were higher in males than in females (25.55% vs. 24.06%, 23.12% vs. 21.45%, 11.60% vs. 6.74%, 3.62% vs. 1.93%, all P<0.05). With increasing age, the positive rate of the initial screening increased, the colonoscopy compliance rate decreased, the precancerous lesion detection rate and colorectal cancer detection rate increased (all P<0.05). From 2013 to 2021, the positive rate of the initial screening among residents showed a downward trend, while the colonoscopy compliance rate showed an upward trend (both P<0.05). Conclusions The detection rate of precancerous lesions in colorectal cancer was 8.87%, and the detection rate of colorectal cancer was 2.67% in Baoshan District from 2013 to 2021. Male and older individuals were the key populations for screening, and the colonoscopy compliance among residents needs to be improved.

Objective To study the relationship between the rheumatoid arthritis (RA) flatfoot and flexor pollicis longus tendon (FHL) lesion.Methods A total of 120 rheumatoid arthritis flatfoot patients (120 feet) was admitted to our hospital,and were examined by uhrasonography.Foot flexor hallucis longus tendon lesions were analyzed.Theses patients were divided into intact tendon group (group A) with 48 cases,tendon inflammation group (group B) with 45 cases,and tendon rupture group (C group) with 27 cases according to the ultrasound flexor hallucis longus tendon lesions degree.Foot bearing radiographs of all patients were measured,and hallux valgus angle between the first and second metatarsal bones were measured,and the relationship between the flexor pollicis longus tendon lesion degree and hallux valgus angle were analyzed.Results There were 48 cases (40％)with normal FHL,45 cases(37.5％)with FHlL inflammation,and 21 cases(22.5％) with FHL fractures.It revealed that HVA was positively correlated with IMA in group A and B (P ＜ 0.05).But there was no correlation between HVA and IMA in group C (P ＞ 0.05).Conclusion FHL is a common RA flatfoot disease,but FHL is not the initial cause of RA hallux valgus,but is positively correlated with the degree of hallux valgus.

Objective To evaluate the general level of asthma management in urban areas of China and further promote the national asthma management plan. Methods A multi-center, cross-sectional survey was carried out in 30 provinces of China (except for Tibet) during Oct 2015 to May 2016. It's a questionnaire-based face-to-face survey which included asthma management using peak flow meter (PFM) and pulmonary function test,medication choice of maintenance therapy and asthma education.Results A total of 3 875 asthmatic outpatients were recruited including 2 347(60.6%)females and 1 528(39.4%)males. The mean age was(50.7±16.7)years ranging from 14 to 99.Only 10.1%(388/3 837)patients used PFM as monitoring, whereas 62.1%(2 405/3 874) patients underwent pulmonary function test during the past year. There were 57.4%(2 226/3 875) patients treated with inhaled cortical steroid plus long-acting β2-agonist combinations (ICS+LABA) as daily medication. 43.3%(1 661/3 836) patients were followed up by physicians. Among this population, 1 362 asthmatic outpatients were recruited, who also took part in the asthma control survey in 2007-2008 in 10 cities.In this subgroup,17.9%(244/1 360)were tested by PFM and 66.6%(907/1 362)by pulmonary function test during last year.As to the medication,63.1%(860/1 362) selected ICS+LABA for daily control. There were 50.4%(685/1 359) patients in the follow-up cohort by physicians.Compared to the similar survey conducted in 2007-2008,the proportion of patients with ICS+LABA regimen and follow-up by physicians were markedly higher,while the rate of PFM use did not have significant improvement. Conclusion Although the present level of asthma management in China is still far from ideal, asthma management has improved compared to 8 years ago. Yet the use of PFM does not significantly improve.Asthma action plan and application of PFM should be further promoted to improve the level of asthma management.

Objective: To investigate the epidemiological characteristics of cluster vomiting diarrhea outbreaks caused by Sapovirus infection in Baoshan District, Shanghai, and to provide reference for the standardized management of cluster vomiting diarrhea events in schools. Methods: The cluster of vomiting and diarrhea outbreaks in Baoshan District from 2017 to 2019 were collected, and the basic information and scene of each cluster were summarized. Sample results were collected and descriptive epidemiological methods were used to analyze the epidemiological characteristics of the outbreak. Results: From 2017 to 2019, a total of 100 cluster vomiting and diarrhea events were reported in Baoshan District, including 9 cases caused by Sapovirus, 120 cases of cluster vomiting diarrhea caused by Sapovirus, with an average incidence rate of 2.37%, including 39 laboratory confirmed cases, the epidemic epidemic time was mainly concentrated in September to November, the places were distributed in 4 primary schools and 5 kindergartens, the main clinical manifestations were vomiting (112/120, 93.33%), abdominal pain (27/120, 22.50%), diarrhea (26/120, 21.67%), compared with Norovirus events, the positive rate, vomiting and fever ratios of Zarovirus were lower than those of Norovirus( χ 2=8.32, 4.52, 14.20, P <0.05). Conclusion In school cluster vomiting and diarrhea events, the positive detection rate of Sapovirus is second enteric vinus behind Norovirus, and it s recommended to formulate a prevention and control plan for Sapovirus infection diarrhea to provide a basis for the on site treatment of school cluster vomiting diarrhea events.
