ObjectiveTo analyze the epidemiological and clinical characteristics of surveillance cases in a sentinel hospital for pertussis in Jiangxi Province in 2019, and to provide corresponding references for the prevention and control of pertussis. MethodsCase investigation of pertussis was conducted among sentinel hospital surveillance cases, collecting their basic information, epidemiological characteristics, clinical characteristics, and other information. ResultsA total of 125 pertussis surveillance cases were investigated in 2019, including 73 clinically diagnosed cases (58.40%) and 52 confirmed cases (41.60%). The age of onset was mainly concentrated in children under 5 years old (108 cases, 86.40%), with the largest number of cases in infants aged less than 1-year-old (48 cases, 38.40%). Most cases had a history of receiving pertussis vaccine before onset (110 cases, 88.00%), and the intervals between the onset date and the date of last dose of pertussis vaccine in the 1‒2 doses group were significantly shorter than that in the 3‒4 doses group (U=-5.990, P<0.001). Probable household transmission of pertussis was found in 3 cases. All cases had cough symptoms, mainly manifested as whooping cough (77 cases, 61.60%), in addition to other main clinical manifestations, such as fever (76 cases, 60.80%), vomiting (30 cases, 24.00%), conjunctival congestion (27 cases, 21.60%), and inspiratory whoop (16 cases, 12.80%). A total of 73 cases (58.40%) experienced complications, including 1 death case. All the cases had multiple medical visit experiences before this visit, with an interval of 2 (0,3) days between the onset date and the first visit date. The misdiagnosis rate at the first medical visit was 88.00% (110/125), and the misdiagnosis rate of the first visit in secondary and primary hospitals was significantly higher than that in tertiary hospitals, exhibiting a statistically significant difference (χ²=21.582, P<0.001). ConclusionThe clinical symptoms of pertussis cases are often atypical, and the first diagnosis is prone to misdiagnosis, so it’s necessary to further strengthen the early diagnosis capabilities for pertussis cases in healthcare institutions, especially in the primary healthcare institutions.

Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Objective:To analyze the epidemic characteristics of mumps in people aged 0-14 years in Jiangxi Province and the vaccination situation of mumps-containing vaccines (including mumps vaccines) from 2015 to 2022 to provide a scientific basis for the prevention and control of mumps epidemic in Jiangxi Province.Methods:The mumps epidemic situation and mumps vaccination data in Jiangxi Province from 2015 to 2022 were obtained from Chinese Disease Prevention and Control Information System and Jiangxi Immunization Program Information System and were analyzed using descriptive epidemiological methods. The chi-square test, cluster analysis, and Cochran-Armitage trend test were used for statistical analysis.Results:From 2015 to 2022, a total of 40 734 cases of mumps were reported in people aged 0-14 in Jiangxi Province, with an annual average reported incidence rate of 53.69/100 000, and the peak of incidence occurred in aged 6-7 years group, and the reported incidence rate was 86.43/100 000. The high incidence seasons in 2015-2019 were summer and winter, and there was no significant high incidence season in 2020-2022. Mumps outbreaks mainly occurred in Shangrao, Ganzhou, and Ji'an, and the outbreak sites were mainly reported primary schools. From 2015 to 2019, the 1-year group was the primary age group for vaccination against mumps, while from 2020 to 2021, it was 0 and 1-year groups.Conclusions:From 2015 to 2022, the incidence of mumps in the population aged 0-14 in Jiangxi Province showed a downward trend, and the peak of incidence occurred in age group 6-7 years. It is suggested to continue to strengthen the coverage rate of 2 doses of mumps vaccination for school-age children and, simultaneously, strengthen the monitoring and prevention of mumps in key places to avoid outbreaks.

Objective To establish an automatic review plan for coagulation tests with image recognition function,and evaluate the correctness and effectiveness of the plan.Methods Artificial intelligence software and hardware were combined to establish an image recognition system that could automatically determine the characteristics of specimens,blood volume and hematocrit.The correctness of the determination results of specimen character was compared with the visual method,the correctness of the determination results of blood volume was compared with the manual measurement method,and the correctness of hematocrit was compared with the hematology analyzer.According to the flow chart,reference interval,medical decision level,critical value range,relevant literature,work experience and historical data,the autoverification rules of coagulation tests were formulated.The autoverification rules were manually verified,and the autoverification pass rate,true positive rate,true negative rate,false positive rate,and false negative rate were calculated.The change of turnaround time in the laboratory after the implementation of the autoverification scheme was evaluated.Re-sults The accuracy rate of sample trait determination in the image recognition system was 96.72％,and the false negative rate of judging hemolytic,jaundice,and lipoid blood samples as normal samples was 0.04％.The image recognition system was compared with the blood volume data of two groups of specimens measured manually,P=0.4881.The image recognition method was not inferior to the manual measurement method.Comparing the two sets of hematocrit data from the image recognition system and the blood cell analyzer,P=0.1130,the image recognition system was not inferior to the blood cell analyzer.A total of 61 automatic re-view rules for coagulation tests had been established,including numerical abnormalities,logical abnormalities,Delta Check,sample quality abnormalities,reaction curve abnormalities,etc.The automatic review pass rate was 76.19％,true positive rate was 23.77％,true negative rate was 76.19％,false positive rate was 0.04％,and false negative rate was 0.00％.After implementing the automatic audit plan,the turnaround time of sam-ples in each quantile was shortened,with an average shortening time of 13.66 min.Conclusion The applica-tion of image recognition technology in the automatic review of coagulation tests makes the automatic review function more automated and scientific,standardizes specimen quality judgment,improves the accuracy of test results,effectively improves work efficiency and saves manpower.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

Irritable bowel syndrome （IBS） is a functional gastrointestinal disease， but it often causes extreme gastrointestinal discomfort and prolonged illness， which seriously affects the quality of life of patients. The global incidence rate is increasing year by year. Clinically， western medicine mainly uses oral antispasmodics， secretagogues， and antidepressants， but there are many disadvantages such as adverse reactions and poor long-term efficacy. Therefore， finding an efficient and safe treatment method is an urgent problem to be solved. A large number of studies have shown that traditional Chinese medicine has definite curative and long-lasting effects on the treatment of IBS， which has become a hot research direction in recent years. By searching Chinese and foreign literature， it is found that electroacupuncture， moxibustion， Chinese medicine monomers， and compound decoctions are the main methods in the mechanism research of traditional Chinese medicine in the treatment of IBS-related pathways， and their signaling pathways involve nuclear transcription factor kappa B （NF-κB）， transient receptor potential vanillin subfamily 1 （TRPV1）， 5-hydroxytryptamine （5-HT）， mitogen-activated protein kinase （MAPK）， and so on. Traditional Chinese medicine can repair intestinal inflammation， reduce visceral sensitivity， enhance intestinal mucosal barrier， and regulate intestinal motility by regulating this series of signaling pathways， thereby playing an important role in the treatment of IBS with multi-level， multi-link and multi-target characteristics. Based on the cell signaling pathways， this paper reviewed the research progress on the mechanism of traditional Chinese medicine in the treatment of IBS， hoping to provide theoretical support and diagnosis and treatment ideas for the clinical treatment of IBS with traditional Chinese medicine.

Periodontitis is a complex chronic inflammatory disease. The invasion of pathogens induces the inflammatory microenvironment in periodontitis. Cell behavior changes in response to changes in the microenvironment, which in turn alters the local inflammatory microenvironment of the periodontium through factors secreted by cells. It has been confirmed that periodontal ligament stem cells (PDLSCs) are vital in the development of periodontal disease. Moreover, PDLSCs are the most effective cell type to be used for periodontium regeneration. This review focuses on changes in PDLSCs, their basic biological behavior, osteogenic differentiation, and drug effects caused by the inflammatory microenvironment, to provide a better understanding of the influence of these factors on periodontal tissue homeostasis. In addition, we discuss the underlying mechanism in detail behind the reciprocal responses of PDLSCs that affect the microenvironment.

IL-22 is a member of IL-10 cytokine family. In recent years, increasing evidence has shown that IL-22 is closely related to the immunity in female reproductive tract, and its role in disease development is two-sided. It can not only maintain the balance of microbiota, enhance the resistance to pathogens and reduce the tissue damage caused by infection, but also promote the development and progression of malignant diseases via various signaling pathways. More studies on the biological characteristics and functions of IL-22 are needed for clarifying the pathogenic mechanism and providing new insight into the diagnosis and treatment of female reproductive tract diseases.

Obesity is a well-known high-risk factor for many kinds of neoplasms. Adipokines secreted by adipose tissue play an important role in the process of obesity promoting tumorigenesis and development, and different adipokines play a role in promoting or suppressing cancer via different signaling pathways. Currently, lifestyle modification to control weight and targeted therapy of adipokines and their receptors are major research directions of cancer treatment, but most of the studies are still in the stage of basic and pre-clinical research. Therefore, the molecular mechanisms of adipokines in promoting or suppressing cancer should be further explored, and the dual inhibitors as well as combined therapy are the key research strategies for adipokines in cancer treatment in the future.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.
