OBJECTIVEThe purpose of this study was to detect the expression of GRHL2 in colorectal cancer (CRC) tissues, and to assess the relationship between GRHL2 expression and clinicopathological features.
METHODSImmunohistochemistry was used to examine GRHL2 in 75 CRC tissues. GRHL2 mRNA and protein levels in the CRC tissues were also analyzed by qRT-PCR and Western blot. The relationship between GRHL2 and clinicopathological features was assessed by Pearson's chi-square (χ(2)) test.
RESULTSPositive immunoreactivity for GRHL2 was detected in the nuclei of CRC cells. GRHL2 expression was increased in CRC tissues compared withthat in the paired non-tumor tissues (61.3% vs. 44.0%, P<0.01). Moreover, qRT-PCR results showed that the relative expression level of GRHL2 mRNA in the colorectal cancer tissue was (2.64±0.35), significantly higher than that of normal mucosa tissue (1.19±0.23, P<0.001). The expression level of GRHL2 mRNA was higher in stage III-IV patients (2.84±0.36) than that of stage I-II cases (2.31±0.32, P<0.05). Western blot results also showed that the expression level of GRHL2 protein in the colorectal carcinoma tissue was significantly higher than that in the normal mucosa (P<0.05). GRHL2 expression was positively correlated with tumor size, TNM stage and Ki-67 (P<0.05, respectively).
CONCLUSIONTaking together, our findings demonstrate that GRHL2 is overexpressed in CRC, and plays an important role in the progression of CRC.

Objective To analyze the epidemiological characteristics and spatial-temporal distribution of drug-resistant tuberculosis in Pudong New Area from 2016 to 2021 and to provide scientific basis for the prevention and control of drug-resistant tuberculosis. Methods The data of tuberculosis patients in Pudong New Area from 2016 to 2021 were collected through the Tuberculosis Information Management System of China Disease Prevention and Control Information System. The geographic information database was established by ArcGIS software and the vector map of Pudong New Area for trend surface analysis and spatial autocorrelation analysis . Results From 2016 to 2021, a total of 3916 patients with etiological positive tuberculosis were found to be drug resistant with the drug resistance rate of 13.13%. The drug resistance rate of each year showed a decreasing trend (χ2trend=14.917, P<0.001). The rates of drug resistance of male, retiree, age 50~<60 years old, 60~<70 years old and recurrent patient were higher. From 2016 to 2021, the incidence of drug-resistant TB showed no spatial aggregation.In the south - north direction, the north is higher than the south generally. In the east - west direction, the west is higher than the east generally. Conclusion Drug resistance screening should be strengthened for men, retirees, over 50 years old, and recurrent TB patients,. Prevention and control measures should be strengthened in street towns with dense population and large floating population.

Journal of Public Health and Preventive Medicine 2020;31(3):126-129
Objective To investigate the effect of comprehensive management mode intervention in elderly patients with moderate/severe chronic obstructive pulmonary disease at stable stage. Methods A total of 150 elderly patients with stable-stage COPD were randomly divided into two groups, 75 in each group. The control group received routine medication, while the observation group was given comprehensive management mode intervention, including health education,rational medication, pulmonary rehabilitation training and psychological guidance. Both groups were treated for 12 months. Differences in lung function parameters, modified Medical Research Council (mMRC) dyspnea scale, COPD assessment test (CAT), 6-minute walk test (6MWT), and frequency of acute exacerbation of COPD (AECOPD) were compared between the two groups. Results: After treatment, FEV1/FVC and FEV1%pred of observation group(57.65±11.62%、61.83±13.50%)were higher than control group(52.38±13.24%、53.42±13.93%)(P<0.05), the mMRC and CAT scores of the observation group were decreased (P<0.05), and the 6MWT was increased (P<0.05), but no significant differences in the control group (P>0.05). Within 12 months of treatment, the frequency of AECOPD in the observation group was less than that in the control group (P<0.05). Conclusions: In the treatment of elderly patients with moderate/severe chronic obstructive pulmonary disease, comprehensive management mode intervention can help delay the deterioration of lung function, correct the difficulty of breathing, improve the quality of life, and reduce the number of AECOPD.

Objective To investigate the pathogens spectrum and epidemiological characteristics of rash and fever illness (RFIs) from January 2010 to December 2017 in Pudong New Area, in order to provide scientific evidence for the prevention and control ofRFIs.Methods Enzyme-linked immunosorbent assay and real-time fluorescence quantitative polymerase chain reaction were used to detect the pathogens of enterovirus, measles virus, rubella virus and others from 2 831 clinical samples, and statistical analysis was performed.Results Pathogens were found in 1 633 samples in total, accounting for 68.59%. The top 4 viruses in the pathogen spectrum were enterovirus (52.54%), measles virus (28.54%), rubella virus (13.04%), and varicella-zoster virus (3.37%). There was significnat difference in the detection rate of rubella pathogens among patients of different genders(P=0.026). In the pathogen spectrum of infections of different age groups, the detection rate of enteroviruses at the age of 3-6 years was higher than that of other age groups. The detection rate of varicella-zoster virus at the age of 6-18 years old was higher than that of other age groups. The detection rate of virus including measles virus, rubella virus, dengue virus and small DNA virus in age of 18 and older was higher than that of other age groups. There was significant difference in the detection rate of pathogens in different age groups (all P<0.05).The incidence of RFIs was the highest in spring (41.52%) and the lowest in winter (15.00%). There was a statistical difference in the detection rate of enterovirus, measles, rubella and dengue virus in different seasons (P<0.05).Conclusions Enteroviruses and measles viruses are the main pathogens leading to RFIs in Pudong New Area, and the activity level of RFIs pathogens should be monitored for a long time.

ObjectiveTo investigate the current status of first aid knowledge among middle-aged and elderly residents aged 50 and above in a community in Shanghai, in order to provide reference for improving the self-rescue and mutual aid capabilities of middle-aged and elderly residents. MethodsA multi-stage stratified random sampling method was used to conduct a survey on 335 residents aged 50 and above in a community in Shanghai using a self-made survey questionnaire. The current situation and related factors of emergency knowledge level of residents aged 50 and above in the community were comprehensively analyzed. ResultsFirst aid knowledge level of 335 residents aged 50 and above was low, and the rate of high cognitive level was only 24.18%. Univariate analysis showed that male residents had a higher awareness rate than female residents (P=0.044), while residents aged 70 and above and 60‒ had lower awareness rates than residents aged 50‒ (P<0.05). Residents with chronic diseases had a higher awareness rate than those who did not (P=0.031). Residents with family members suffering from chronic diseases had a higher awareness rate than those without (P<0.001). Experience of first aid training affected residents’ awareness of first aid (P=0.003). ConclusionThe level of first aid knowledge among middle-aged and elderly residents aged 50 and above in the community is low. Age, the presence of chronic diseases in family members, and emergency training are independent and relevant factors that affect the awareness of first aid knowledge among middle-aged and elderly residents. The government and relevant institutions should explore the establishment of a standardized emergency response training system, implement classification and grading for middle-aged and elderly groups with different characteristics, and provide targeted emergency training to strengthen their self-rescue and mutual aid capabilities and improve the success rate of pre-hospital emergency care.

Objective: To investigate the epidemiological characteristics of Yersinia enterocolitica in patients with diarrhea in Pudong New Area, Shanghai. Methods: Active surveillance of diarrhea was conducted in 14 sentinel hospitals (three tertiary-level hospitals, nine secondary-level hospitals, and two primary-level hospitals) from January 2013 to December 2019 in Pudong New Area of Shanghai, China base on their location, catchment area, and patient volume. Cold enrichment method was used to isolate Y. enterocolitica and further detection of bioserotype, virulence genes and antimicrobial susceptibility of the isolates were conducted. The difference of rates was determined using chi-square test or Fisher's exact test. Results: A total of 12 941 diarrhea cases were included, and 0.7% (88/12 941) cases were confirmed with Yersinia enterocolitica infection. 67.0% (59/88) cases were single infection, 33.0% (29/88) cases were mixed infections. Detection rates of Y. enterocolitica increased annually (0.3%-1.2%) and were highest in children<5 years of age (1.1%, 37/3 218) and in spring (1.1%, 32/2 998) (χ2 were 18.64 and 9.76, respectively, P<0.05). 58.0% (51/88) cases had watery diarrhea, 15.9% (14/88) had fever and 14.8% (13/88) had vomiting. The predominant bioserotypes were 3/O:3 (53.4%, 47/88), followed by 1A/O:8 (15.9%, 14/88) and 1A/O:5(6.8%, 6/88), respectively. Bioserotype 3/O:3 counted for the highest proportions (89.2%, 33/37) in children <5 years of age. All the strains of bioserotype 3/O:3 harbored ail, ystA, yadA and virF genes, which encoded pathogenic Y. enterocolitica. 11/14 strain of 1A/O:8 and 4/6 strains of 1A/O:5 harbored ystB gene. Most strains were resistant to ampicillin (80.7%,71/88) and amoxicillin/clavulanic acid (71.6%,63/88), and 63.8% (56/88) strains were multidrug resistance (MDR). The difference of antimicrobial resistance rates between 3/O:3 and non 3/O:3 was statistically significant in ampicillin, cefoxitin, nalidixic acid, tetracycline and ampicillin/sulbactam (χ2 was 14.68, 43.80, 41.86, 30.54 and 5.07, respectively, P<0.05). Conclusion: The detection rate of Yersinia enterocolitica was higher in children than in adults in Pudong New Area , Shanghai. The predominant bioserotype was pathogenic 3/O:3 with multidrug resistance.

ObjectiveTo analyze the epidemic characteristics of measles and rubella in Pudong New Area of Shanghai from 2013 to 2022, and to provide data support for the elimination of measles and rubella. MethodsEnzyme linked immunosorbent assay was used to detect IgM antibodies in serum samples. The sequence of 630 nucleotides at the C-terminal of N gene of measles virus was amplified by reverse transcription-polymerase chain reaction and the phylogenic tree was constructed. ResultsA total of 1 529 suspected cases of measles were detected from 2013 to 2022, among which the positive rate of measles IgM antibody was 33.55% (513/1 529). The highest positive rate (20.73%) was from March to May , and the positive rate of rubella IgM antibody was 6.80% (104/1 529). The positive rate of both IgM was higher in males than that in females (P<0.05). The IgM against measles was mainly detected in 0‒ years old (63.16%, 96/152) and 20‒ years old (45.61%, 161/353). The IgM against rubella was mainly detected in 10‒20 years old (27.27%, 18/66). The IgM antibody could be detected more easily from 4 to 28 days after eruption, and the IgM antibody positive rate of measles/rubella from 2020 to 2022 was significantly lower than previous years (2013‒2019). There were 2 D8 genotype strains, and the rest were H1a gene subtypes. ConclusionThe positive rate of IgM antibodies against measles/rubella in Pudong New Area of Shanghai decreased significantly. People aged 0‒ years and 20‒ years old are more susceptible to measles, and rubella is concentrated in 10‒ years old. It is necessary to strengthen the vaccination of school-age children, in order to achieve the goal of eliminating measles. The age group with high risk of exposure should be checked for vaccination status to ensure the enhanced immunization, and the surveillance of imported measles cases should be strengthened.

Background Papillary thyroid cancer is the result of a variety of pathogenic factors. The prevalence of papillary thyroid cancer varies greatly in different regions, and the disease is more harmful to women. Objective This study aims to explore the relationship between reproductive factors and papillary thyroid cancer, and to provide basic data for prevention and control of the disease. Methods A 1∶1 age (±3 years) matched case-control study was conducted in 331 pairs of newly confirmed papillary thyroid cancer cases and controls from two hospitals in Shanghai from November 2012 to December 2013. Comparisons were made in the history of menstruation, pregnancy, gynecological and breast diseases, and other variables between the two groups. Results The results of univariate analysis indicated that the proportions of education below bachelor degree, married, and mainly manual workers in the case group were significantly higher than those in the control group (P<0.05); the proportion of those with a family history of thyroid diseases in the case group was significantly higher than that in the control group (P<0.05); the proportions of the cases with irregular menstruation (77.34%), a history of using oral contraceptive or hormone drugs (24.77%), a history of benign gynecological diseases (31.72%), and a history of gynecological surgery (9.67%) were significantly higher than the proportions in the control group (P<0.05). After adjusting potential confounding factors such as history of CT examination, age, kinds of family salt, total iodine intake every day, education level, occupation, marital status, body mass index, and family history of thyroid diseases, the results of multiple logistic regression analysis showed that irregular menstruation (OR=1.767, 95%CI: 1.122-2.782; P=0.014), surgical menopause (OR=12.787, 95%CI: 3.202-51.057; P<0.001), pregnancy >1 time (OR =2.490, 95%CI: 1.196-5.184; P=0.015), and the history of using oral contraceptive or hormone drugs (OR=2.389, 95%CI: 1.338-4.268; P=0.003) were the risk factors of papillary thyroid cancer. Conclusion Irregular menstruation, surgical menopause, history of pregnancy, and history of using oral contraceptive or hormone drugs might be the risk factors of papillary thyroid cancer. To reduce the incidence of papillary thyroid cancer, strengthened health education and rational use of contraceptives are recommended.
