Objective To explore the status quo of intensive statin therapy in hospitalized patients with acute myocardial infarction (AMI) from 2001 to 2011 and analyze its influence factors.Methods We obtained in-formation of AMI patients in 2001,2006,and 2011 from their medical record. Intensive statin therapy was defined as statin regiments with expected LDL-C lowering of at least 40%.Results Among 767 patientswith definite dosage of statin,the use frequencyof intensive statin increased from 0%in 2001 to 60.77% in 2006,and 88.71% in 2011 (P<0.0001).Morefemalesreceived intensive statin therapy than males(P=0.015)and the use frequency of intensive statin therapy in smoking patients was obviously more frequent than that in hypertension ,diabetes mellitus and hy-perlipidemia patients (P=0.0081).The use frequency of intensive statin therapy in patients with ischemic stroke was significantly lower than that in those with AMI or coronary artery disease(P=0.0437). AMI patients with STele-vatedwere much less likely received intensive statin therapy than those with non-ST elevated(P<0.0001). Chest pain,cardiac shock or cardiac arrest and the base level of LDL-C exerted no influence on the use of intensive statin therapy(P>0.05). Conclusions The use frequency of intensive stain therapy among AMI patientsincreasesyear by year and it is affected by sex,risk factors,history of disease and type of infarction.

Methods The data of 27 AIP death cases were retrospectively analyzed. The data included the population characteristics, toxicology, pathology and causes of death. Results All 27 patients had clinical symptoms including fever, cough and chest tightness, 25 patiens of them were treated as upper respiratory tract infection in local hospital, and finally died of deteriorating condition. The forensic diagnosis after autopsy showed the 27 cases were died of respiratory failure caused by AIP. Conclusion AIP is a disease with rapid progression and often leads to medical disputes,the patient's families often have different opinion on the death cause of patients with the hospital,so forensic identification of the cause of death is conducive to resolve the disputes.

Abstract: Objective To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) in Ankang City from 2011 to 2021, so as to provide a scientific basis for the formulation of PTB prevention and control strategy. Methods Descriptive statistics were used to analyze the epidemiological characteristics of PTB in Ankang City from 2011 to 2021, and a time series model was established to quantitatively predict the incidence of pulmonary tuberculosis in 2023. Results The incidence rate in Ankang City showed a significant upward trend from 2011 to 2017, and a more obvious downward trend in 2017-2021 (P<0.05), and the decrease rate in 2021 was 40.36% compared with that in 2017. The proportion of etiological positivity increased from 12.5% in 2014 to over 50.00% after 2019. The incidence season was mainly concentrated in the first quarter, accounting for 28.39% of the annual incidence. High incidence areas were concentrated in the south of Ankang: Langao County, Ziyang County and Zhenping County, with 128.32/100 000, 117.07/100 000 and 110.44/100 000, respectively. Low incidence areas were located in the north of Ankang: Ningshan County, with 60.62/100 000. Farmers and students were the high incidence groups, accounting for 81.80% and 4.97% of the total cases respectively. The incidence of young children was relatively low, but cases were reported every year. The incidence rate of male was 2.39 times that of female. The age of onset increased significantly from 15 years old, and the peak incidence was in the age group of 60-<80 years old, followed by the age group of 45-<60 years old, the average annual incidence was 136.44/100 000 and 104.47/100 000, respectively. The model ARIMA(0,1,1)(0,1,1)12 predicted that the incidence of the disease generally increased from October 2022 to March 2023, then steadily decreased, and increased again in December. Conclusions The incidence of tuberculosis varies in different areas of Ankang City, and males, farmers, students and the elderly are all factors of high incidence of tuberculosis. Therefore, different prevention and control strategies should be adopted according to the characteristics of population in different areas. The number of cases in Ankang City in 2023 showed an overall downward trend, which can provide a reference for the prevention and control of PTB.

Objective To compare the clinical efficacies of vasiculation moxibustion with pastes prepared in different ways and at different acupoint groups in treating allergic rhinitis due to deficient cold of lung qi. Method Eighty subjects were randomized into 4 groups, 20 in each group. Raw Bai Jie Zi (Semen Brassicae) was used in the vesiculation paste for group 1 and 2;stir-baked Bai Jie Zi (Semen Brassicae) was used for group 3 and 4. In group 1 and group 3, bilateral Feishu (BL 13), Fengmen (BL12), and Gaohuang (BL 43) were selected; in group 2 and group 4, bilateral Dazhu (BL11), Geshu (BL17), and Shenshu (BL23) were selected. The symptom and sign scores were compared before and after intervention. Result There were significant differences in comparing the symptoms and signs among the four groups (P＜0.05), and paired comparisons showed that the therapeutic efficacies of group 1 and group 3 were significantly higher than that of group 2 and group 4 (P＜0.05), while the differences in the therapeutic efficacy between group 1 and group 3, group 2 and group 4 were statistically insignificant (P>0.05). Conclusion Vesiculation moxibustion at the point group of Fengmen (BL12), Feishu (BL13), and Gaohuang (BL43) can markedly improve the symptoms and signs of allergic rhinitis due to deficient cold of lung qi;raw and stir-baked Bai Jie Zi (Semen Brassicae) can work equally in vesiculation paste for allergic rhinitis.

Kidney injury and decreased chemosensitivity of tumor cells are obstacles with cisplatin (CDDP) chemotherapy. Down-regulation of the organic cation transporter 2 (OCT2) and multidrug resistance-associated protein 2 (MRP2) is a key means to alleviate CDDP-induced kidney injury and increase chemosensitivity. Astragaloside IV (AS IV) is obtained from the well-known traditional Chinese herb Astragalus membranaceus. This study explored the role of AS IV in preventing kidney injury and enhancing the antitumor effect of CDDP by suppressing OCT2 expression in kidney and MRP2 in tumors. This project was reviewed and approved by the Animal Ethics Committee of the First Hospital of Jilin University. The effects of AS IV on CDDP inhibition of tumor growth and promotion of apoptosis were assessed in Lewis lung tumor (LLC)-bearing mice by H&E and TUNEL staining. Kidney injury was assessed by serum biochemical parameters and H&E staining. We used Western blotting and immunohistochemistry assays to detect OCT2 and MRP2 expression in kidney and tumor. The concentration of CDDP in kidney and tumor was measured by HPLC-MS/MS. AS IV enhanced CDDP chemosensitivity by increasing tumor cell apoptosis and slowing tumor growth, and decreased kidney injury as evidenced by lower blood creatinine (Cr) and blood urea nitrogen (BUN). Co-administration of AS IV suppressed MRP2 overexpression induced by CDDP in tumor tissues and may be an important mechanism for enhancing CDDP chemosensitivity. Moreover, AS IV reduced CDDP-induced kidney injury in mice along with suppression of OCT2 expression in kidney. The concentration of CDDP was increased in tumor but decreased in kidney. In total, AS IV not only enhanced the antitumor effect of CDDP by suppressing MRP2 expression in tumor cells, but also decreased kidney injury induced by CDDP. The results provide new insight into the combined use of a chemotherapy drug and natural ingredients to treat cancer.
