BACKGROUND: TRIM proteins are important members of E3 ubiquitin ligases, and many studies have confirmed that TRIM family members play an important role in the development of various tumors. We found that TRIM59 expression level in non-small cell lung cancer (NSCLC) was significantly increased through second-generation sequencing. The purpose of this study was to investigate the expression of TRIM59 in NSCLC and its relationship with the clinicopathological parameters as well as the prognosis of patients. METHODS: The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets were excavated to analyze the expression of TRIM59 mRNA in NSCLC and its relationship with the prognosis of patients; The expression of TRIM59 protein in 90 tumor tissues and adjacent tissues was detected by immunohistochemical staining, and the relationship between the expression of TRIM59 protein and clinicopathological parameters and prognosis was analyzed. RESULTS: Overexpression of TRIM59 mRNA in tumor tissues predicted poor prognosis. The expression level of TRIM59 protein was significantly higher in tumor tissues than in adjacent tissues, and TRIM59 protein expression was correlated with tumor size (P=0.007), tumor differentiation (P=0.009), tumor-node-metastasis (TNM) stage (P=0.003) and lymph node metastasis (P=0.003). Multivariate Cox regression analyses showed that along with TNM stage, overexpression of TRIM59 could be considered an independent prognostic factor for NSCLC patients. CONCLUSIONS The expression of TRIM59 is closely related to the prognosis of NSCLC patients, and it is an independent risk factor for NSCLC patients.

Air pollution, climate change, and reduced biodiversity are major threats to human health with detrimental effects on a variety of chronic noncommunicable diseases in particular respiratory and cardiovascular diseases. The extent of air pollution both outdoor and indoor air pollution and climate change including global warming is increasing-to alarming proportions particularly in the developing world especially rapidly industrializing countries worldwide. In recent years, Asia has experienced rapid economic growth and a deteriorating environment and increase in allergic diseases to epidemic proportions. Air pollutant levels in many Asian countries especially in China and India are substantially higher than are those in developed countries. Moreover, industrial, traffic-related, and household biomass combustion, indoor pollutants from chemicals and tobacco are major sources of air pollutants, with increasing burden on respiratory allergies. Here we highlight the major components of outdoor and indoor air pollutants and their impacts on respiratory allergies associated with asthma and allergic rhinitis in the Asia-Pacific region. With Asia-Pacific comprising more than half of the world's population there is an urgent need to increase public awareness, highlight targets for interventions, public advocacy and a call to action to policy makers to implement policy changes towards reducing air pollution with interventions at a population-based level.

Objective: To evaluate the effects of standardized management of hypertension on blood pressure control of hypertension patients with diabetes mellitus in workplace population. Methods: Taking the type and size of workplace into consideration, 61 work sites were selected in different provinces by using epidemiological field trial method. In each selected province, 2-4 work sites with similar economic and medical conditions were chosen, among which 1-3 were designated as the intervention group and the other one as the control group. In total, 443 patients with hypertension and diabetes mellitus were included, with 347 patients in the intervention group and 96 patients in the control group. After training, doctors conducted standardized management for patients in the intervention group for a period of 24 months, following up with them regularly once a month, and recorded changes in blood pressure, risk factors, target organ damage, and treatment, while the control group had no special intervention, and relevant information was collected only at baseline and 24 months. Blood pressure, blood pressure control rate, and blood glucose changes were compared between the two groups. Results: After receiving standardized management of hypertension, the control rate of hypertension for patients with both hypertension and diabetes mellitus in the intervention group increased from 24.2% to 63.7% (P<0.05) and the participants’ blood pressure also significantly decreased, by 10.2 (11.9-8.4) mmHg (1 mmHg=0.133 kPa) for systolic blood pressure and 7.7 (8.8-6.6) mmHg for diastolic blood pressure (P<0.05); moreover, the blood glucose also decreased slightly (P<0.001). In addition, the control rate of blood pressure increased to 63.7% with the increase of management time. In the control group, the control rate of hypertension increased to 46.9% (P<0.05) and the systolic and diastolic blood pressure decreased by 5.6 (8.9-2.2) and 4.5 (6.6-2.4) mmHg (P<0.05). Conclusions The standardized management of hypertension in the workplace can effectively reduce overall blood pressure levels and improve the control rate of hypertension in the working population.

Tetanus consists of neonatal tetanus and non-neonatal tetanus. Non-neonatal tetanus remains a serious public health problem, although neonatal tetanus has been eliminated in China since 2012. Non-neonatal tetanus is a potential fatal disease. In the absence of medical intervention, the mortality rate of severe cases is almost 100%. Even with vigorous treatment, the mortality rate remains 30%-50% globally. These specifications aim to regulate non-neonatal tetanus diagnosis and treatment in China, in order to improve medical quality and safety. These specifications introduce the etiology, epidemiology, pathogenesis, clinical manifestations and laboratory tests, diagnosis, differential diagnosis, grading and treatment of non-neonatal tetanus.

Objective: To explore hematological and genotypic characteristics of patients with hemoglobin E (Hb E) disorders from Yunnan Province. Methods: One hundred individuals with Hb E disorders indicated by high performance liquid chromatography (HPLC) were subjected to genetic testing through multiple gap-PCR and reverse dot-blotting analysis. Results: All patients were found to harbor a mutation to the 26th codon of the β-globin chain (HBB: c. 79G>A). Ninety patients were heterozygotes, and 10 co-inherited c. 79G>A and an α-thalassemia mutation (7 αα/-α^3.7, 2 αα/--^SEA and 1 -α^3.7/-α^3.7). Hematological characteristics of the heterozygotes were: Hb A2 (26.02±3.64)%, Hb F(1.35±1.25)%, MCV(78.83±4.68) fl, MCH(26±1.54) pg, MCHC (329.65±10.73) g/L, HGB (141.08±16.53) g/L, while that of the co-inherited cases was decided by the type of α-thalassemia mutation. Conclusion Hb E can be effectively detected by HPLC. The type of α-thalassemia mutations will determine hematological features of co-inherited cases. Hb E disorders may be missed by relying only on routine blood test upon prenatal screening.

Objective: To identify the incidence of hypertension, overweight/obesity in middle-aged population in China, and explore their impact on cardiovascular events. Methods: From 2009 to 2010, 12 areas were sampled in China, and about 1 000 subjects aged 35 - 64 from each area were enrolled to collect the basic information, physical examination and blood tests were also performed. From 2016 to 2017, data from 8 835 subjects, who completed the 6 years follow-up, were analyzed.Blood pressure and body mass index(BMI) at both baseline and the follow-up, as well as incidence of hypertension, overweight and obesity, were calculated. Cox proportional hazard model was used to investigate the impacts of hypertension, overweight and obesity on cardiovascular events after adjusting confounders. Results: At the end of follow-up, both BMI and systolic and diastolic blood pressure increased significantly compared with the baseline levels (all P<0.001). The cumulative incidence of hypertension, overweight and obesity within 6 years was 39.3%(1 146/2 918), 11.5%(406/3 544) and 4.3%(302/7 025), respectively. Compared with subjects with both normal BMI and blood pressure, people with overweight, obesity, hypertension, overweight with hypertension, and obesity with hypertension faced significantly increased risk of cardiovascular disease (HRs (95%CIs) were 2.394(1.130-5.073), 3.341(1.454-7.674), 6.047(2.978-12.279), 5.808(2.924-11.539) and 8.716(4.391-17.302), respectively, all P<0.05), after adjusting for other confounders. Conclusions The incidence of overweight, obesity, and hypertension is high in middle-aged people in China. Overweight, obesity and hypertension are associated with significantly increased risk of cardiovascular events during the 6 years follow up.

Objective: To explore the clinical applications of second generation colon capsule endoscopy (CCE-2). Methods: From July 2017 to December 2018, at the First Affiliated Hospital, College of Medicine, Zhejiang University, 40 outpatients and hospitalized patients who underwent CCE-2 examination were enrolled. The examination results were analyzed by an expert gastroenterologist with rich experience in small intestinal and colon capsule endoscopy. The stomach, small bowel and colon transit time, the score of colon cleansing quality, the completion rate of colon capsule examination, lesion detection and adverse effects were observed. Chi-square test and Student′t test were used for statistical analysis. Results: The whole gastrointestinal tract examination was completed during the capsule running time in 65.0% (26/40) of the patients. The average stomach transit time was (0.92±0.74) h, the small bowel transit time was (3.93±1.51) h and the colon transit time was (4.89±0.61) h. The capsule running time of patients who completed the whole gastrointestinal tract examination was shorter than that of patients who did not complete the whole gastrointestinal tract examination ((9.44 ± 3.53) h vs. (15.47±2.09) h), and the difference was statistically significant (t=6.79, P<0.01). The qualified rate of colon preparation was 67.5% (27/40). There were no statistically significant differences in colon transit time or capsule excretion time between patients with qualified colon preparation and poor colon preparation ((4.43±3.33) h vs. (5.96 ± 2.44) h; and (9.06 ± 3.91) h vs. (10.29±2.47) h; t=1.17 and 0.81, both P>0.05). A total of 33 (82.5%) patients had gastrointestinal lesions detected by colon capsule, including three cases of esophageal lesions (inflammation and mass), 21 cases of gastric lesions (chronic gastritis, mucosal protrusion, polyp and ulcer), nine cases of small bowel lesions (polyp, ulcer and vascular malformation) and 19 cases of colonic lesions (diverticulum, polyp, rectitis, mucosal erosion, ulcer and vascular malformation, internal hemorrhoids). Among them, there were 11 patients with two or more lesions. No adverse events occurred during the examination and all the capsules were excreted within 48 hours. Conclusion CCE-2 with high safety and good tolerance can be used for whole gastrointestinal tract examination.

Objective: To explore the relationship between fetal nuchal translucency (NT) in the first trimester and pregnancy outcome. Methods: A prospective cohort study was conducted in Nanjjing Drum Tower Hospital from December 2015 to December 2018, 4 958 singleton pregnant women were enrolled to screen fetal ultrasound structure and serology in the first trimester, ultrasound in the second trimester and neonatus physical examination 28 days after birth. According to the results of NT, 167 cases of fetus with increased NT (≥3.0 mm) and 4 791 cases of normal NT were divided, moreover, 86 cases with isolate increased NT and 81 cases of increased NT combined with structural abnormality. The prognosis of fetuses with different NT thickness was analyzed, and the pregnancy outcome of fetuses with isolate increased NT or combined with structural abnormality were analyzed. In the first trimester, if the fetal structure was abnormal or the serological screening result was high risk, the chromosomal microarray analysis (CMA) would be performed by chorionic villus sampling to determine the prenatal diagnosis. Results: (1) The pregnancy outcome for fetus of normal NT: there were 4 791 cases with normal NT. Totally, 4 726 cases with normal NT and no structural abnormalities were screened out in the firsttrimester. In this group, 5 cases of aneuploidies were diagnosed based on high risk of maternal serum biomarkers and 83 cases of structural abnormalities were screened out in the subsequent ultrasound scan and the neonatal examination. Another 65 cases with normal NT present complicated with structural anomalies were screened out in the first trimester and 4 cases were diagnosed as aneuploidies. (2) The pregnancy outcome for fetus of isolate increased NT: 66 (76.7%, 66/86) cases of isolated increased NT were performed CMA, 3 cases were diagnosed as trisomy 21 and terminated pregnancy. Another 4 cases were terminated pregnancy privately without cytogenetic diagnosis. No further anomalies were found in 79 cases till 6 to 21 months postnatally. (3) The pregnancy outcome for fetus of increased NT with structural anomalies: increased NT present with structural anomalies were screened out by detailed anomaly scan in the first trimester and 32 of them were confirmed as aneuploidies. In this group, 70 cases terminated pregnancy, 2 cases had spontaneous miscarriages and 9 cases had liveborns (1 newborn was found ventricular septal defect). (4) The pregnancy outcome for fetus of increased NT with or without structural anomalies: the percentage of aneuploidies in fetuses with isolated increased NT (3.5%, 3/86) was significantly lower than those with structural abnormalities (39.5%,32/81). The healthy survival rate in fetuses with isolated increased NT (91.9%,79/86) was significantly higher than those with structural abnormalities (9.9%, 8/81). Conclusions A detailed first-trimester anomaly scan could improve prenatal screening efficiency of birth defects. Compared to the fetuses with increased NT combined with structural abnormalities, the healthy survival rate of fetuses with isolated increased NT based on detailed first-trimester anomaly scan is higher and the percentage of fetal aneuploidies is lower.

At the end of December 2019, acute respiratory infectious diseases caused by a new type of coronavirus were prevalent in Wuhan and other cities of China. Different from radiology examinations, the protocols of nuclear medical imaging examinations are complicated, in which more workplaces and staff are needed, resulting more complex management of patients and higher protection requirements. Combined with the characteristics of SPECT and PET imaging procedures, this paper puts forward some suggestions on the protective process of imaging examinations for patients with confirmed or suspected novel coronavirus infection. The main purpose is to protect medical staff from virus infection, effectively reduce the risk of virus transmission during the examination process, and ensure the medical quality and safety.
