Epidemiological and Clinical Characteristics of Measles in Jinan, Shandong Province, China, from 1991 to 2022.

Objective: This study aimed to analyze the epidemiological and clinical characteristics of measles in Jinan, Shandong, China, over a 32-year stage to facilitate measles prevention in the future. Methods: Data on measles cases from 1991 to 2022 were obtained from the public health department and medical records of patients at Shandong Public Health Clinical Center. Retrospective analysis was conducted on the distribution of measles cases in different years, months, and age groups, and observation of the differences in clinical manifestations and complications among different age groups. Results: From January 1991 to December 2022, 7531 measles cases were recorded at Shandong Public Health Clinical Center. During the 32-year period, there were two outbreaks of measles in 2008 and 2016, respectively. During the COVID-19 pandemic period from 2020 to 2022, the number of cases reached the lowest point in the past 30 years. The number and percentage of cases in the 0-1y groups was significantly higher than in other age groups, and 97.75% patients in this group did not receive measles vaccine. Complications such as pneumonia and myocarditis appeared more frequent in patients under 12 years of age, but liver function damage is more common in adult patients. Conclusion: Although the measles epidemic has been greatly controlled since the use of measles vaccine, intermittent outbreaks still exist, so there is still a long way to go to eliminate measles. The proportion of infants under the age of 1 without measles vaccine and adults over 24 years old accounts for nearly 80% of the total. This group of people should be of concern, and feasible measures should be designated to protect these susceptible populations.

The regularity of nourishing-yin prescription for treating ascites due to hepatitis B cirrhosis based on data mining technology.

Background: Clinically, Chinese medicine is mostly used to treat ascites due to hepatitis B cirrhosis by nourishing-yin. We summarize the pattern of prescriptions for nourishing-yin inascites due to hepatitis B cirrhosis based on data mining to better use traditional Chinese medicine (TCM) to treat cirrhotic ascites in hepatitis B. Methods: Articles published from 2000 to 2020 on ascites due to hepatitis B cirrhosis were searched in the Chinese National Knowledge Infrastructure and Chinese Science and Technology Journal Database. The results of the search were screened and then treated as the data sources in turn. Based on the data sources, a prescription database of ascites due to hepatitis B cirrhosis was constructed. The data mining was conducted by statistical analysis of frequency and association. Core herbs, including the property and flavor, channel tropism, regularities of medicinal recipes, and core sets, among others, were examined. Results: Through combing 199 articles, a total of 201 prescriptions were selected, involving 138 kinds of herbs. The efficacy of cold herbs was slightly higher than that of warm herbs. The main flavors of herbs were sweet, bitter, and pungent. There were 30 herbs used ≥26 times in 201 prescriptions. The highest frequency of use was Poria cocos, followed by atractylodis macrocephalae, and radix astragali. Ninety-nine commonly used drug combinations were obtained according to the association rules, of which there were 60 associated drug groups with a frequency ≥34, of which the highest frequency was poria cocos-rhizoma atractylodis macrocephalae, poria cocos-oriental water plantain rhizome, poria cocos-radix astragali. Frequent medicinal recipes consisted largely of medicines for tonifying deficiency, including diuretics for eliminating dampness, medicines for promoting blood circulation and removing blood stasis, and supplements for clearing heat and regulating qi. Conclusions: Through data mining, it was found that when TCM treats ascites due to hepatitis B cirrhosis, it attaches importance to using methods of tonifying deficiency and invigorating spleen for diuresis based on nourishing-yin to improve the clinical efficacy, which can provide reference for TCM's clinical use of nourishing-yin to treat ascites due to hepatitis B cirrhosis.

Dynamic profiles of SARS-Cov-2 infection from five Chinese family clusters in the early stage of the COVID-19 pandemic.

Although several cases of family clusters with SARS-Cov-2 infection have been reported, there are still limited data preventing conclusions from being drawn regarding the characteristics and laboratory findings in the COVID-19 population within family clusters. In the present study, we retrospectively collected five family clusters with COVID-19 and summarized the dynamic profiles of the clinical characteristics, laboratory findings, immune markers, treatment and prognosis of this population. Furthermore, we also compared clinical and laboratory data between the SARS-Cov-2 infection with family cluster (n = 21) and those without family cluster (n = 16). We demonstrated that the duration of SARS-Cov-2 replication might be varied based on the different family clusters due to their different genetic backgrounds. The onset improved lung radiology might start at the end of the SARS-Cov-2 positive period. Furthermore, the obtained results demonstrated that similar basic characteristics and clinical findings seem to exist between the cases with SARS-Cov-2 and without family clusters. The serum level of ferritin might have a different biological function and be a new biomarker for the family cluster. Further studies with larger numbers of patients are required.

A Newly Established Severity Scoring System in Predicting the Prognosis of Patients with Severe Fever with Thrombocytopenia Syndrome.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by novel Bunyavirus. Due to the peculiarity of SFTS, accurate assessment is difficult to achieve with the current score systems. This study aimed to establish a new severity scoring system in predicting the prognosis of patients with SFTS. We included 123 patients with SFTS: 92 patients (45 males and 47 females), aged 59 ± 12 years, in survive group and 31 patients (17 males and 14 females), aged 61 ± 10 years, in death group. The lactate dehydrogenase (LDH), the activated partial thromboplastin time (APTT), the saturation of pulse oximeter oxygen (SpO2) and Glasgow Coma Scale (GCS) were measured. SFTS severity scoring system was set up based on the above four factors and compared with the Rapid Emergency Medicine Scores (REMS) and Acute Physiology and Chronic Health Evaluation (APACHE II) Scores. Four parameters in the death group were all significantly higher than survival group. The areas under the curves (AUC) of REMS, APACHE II scores and SFTS severity scores were 0.734, 0.746 and 0.780 respectively. The Youden index of the SFTS severity score was the highest among all the three scores (P < 0.01). If 15 was used as the cutoff value, the sensitivity and specificity of SFTS severity score in predicting the death risk for the patients were 74.2% and 76.1% respectively. The newly established SFTS severity scoring system is more efficient to predict the prognosis of patients with SFTS, compared with REMS and APACHE II.
