Case report of scrub typhus complicated by hypokalemia and multiple organ dysfunction syndrome

ABSTRACT CONTEXT: Scrub typhus, caused by Orientia tsutsugamushi, has a wide range of clinical manifestations, including meningoencephalitis, acute renal failure, pneumonitis, myocarditis, and septic shock. However, there are no documented cases of scrub typhus with hypokalemia. In this report, we present a case of scrub typhus with hypokalemia and multiple organ failure syndrome, highlighting the importance of electrolyte imbalance in patients with scrub typhus. CASE REPORT: A 59-year-old woman presented to the emergency department with abdominal pain that had been present for 1 day. On admission, the physical examination and laboratory test results indicated that the patient had renal, liver, and circulatory failure, and hypokalemia. She developed meningitis and disseminated intravascular coagulation during hospitalization. She recovered with appropriate management, and was discharged on day 17. CONCLUSION: This report highlights the potential for atypical presentations of scrub typhus, including a previously undocumented association with hypokalemia. Although the contribution of hypokalemia to the patient's clinical course remains uncertain, this case underscores the importance of considering electrolyte imbalance in the management of patients with scrub typhus. Further research is warranted to better understand the relationship between scrub typhus and electrolyte imbalance.

Analysis of the current situation and trend of infectious disease public health emergencies in Hainan Province from 2013 to 2022 / 中国热带医学

@#Abstract：Objective To evaluate the basic development status of public health emergencies of infectious diseases in Hainan Province from 2013 to 2022, analyze the distribution and characteristics of these emergencies, as to provide important scientific basis for the study and formulation of economic health development planning policies, for the health security policies and infectious disease prevention and control strategies in Hainan Province. Methods The relevant statistical data of public health emergencies involving infectious diseases reported in Hainan Province from 2013 to 2022 were collected, and the status quo of these emergencies was analyzed by using descriptive data statistical analysis method. The ARIMA model was used to predict the number of public health emergencies reported by infectious diseases in Hainan Province from 2023 to 2025. Results From 2013 to 2022, a total of 482 public health emergencies were reported in Hainan Province, of which 426 were infectious disease public health emergencies, accounting for 88.38%, with a total of 8 876 cases, an incidence rate of 0.61%, and eight deaths, a case fatality rate of 0.09%. The major public health emergencies of infectious diseases were unclassified events and general events, accounting for 69.25% and 29.58%, respectively. The main diseases were novel coronavirus infection, chickenpox and hand, foot and mouth disease, accounting for 45.07%, 15.49% and 11.97%, respectively; in terms of time distribution, the number of reported incidents showed an upward trend over time, with a decline in 2021, and mainly had three peak periods, April, August and December, with a total of 220 cases reported; in terms of regional distribution, the major cities and counties reported were Haikou, Wanning and Wenchang, accounting for 27.46%, 19.25% and 9.86%, respectively; in terms of location distribution, the events mainly occurred in schools, accounting for 42.02% of the total number of incidents. The ARIMA(1, 1, 0) model was used to predict infectious disease public health emergencies, and the results showed that the forecast state would be stable from 2023 to 2025, with no obvious upward trend, that is, the fluctuation range of public health emergencies related to infectious diseases in Hainan Province would be stable in the next three years. Conclusion The number of infectious disease public health emergencies reported in Hainan Province from 2013 to 2022 has increased year by year, with a decline in 2021. Although the forecast shows that public health emergencies such as infectious diseases are relatively stable with no obvious upward trend, the prevention and control of the epidemic should not be taken lightly. Hainan Province should continue to increase the investment in monitoring public health emergencies, improve the information system of public disease prevention and control, and carry out real-time monitoring of public health emergencies of infectious diseases.

Autophagy and Inflammation in Fish / 中国生物化学与分子生物学报

Autophagy and inflammation are the important physiological reactions, especially in innate immunity. Autophagy, as a conservative metabolic process, can degrade its own disorder components through lysosomes to maintain cell homeostasis. Autophagy plays a pivotal role in degrading damaged organelles, resisting pathogenic infection and regulating inflammatory response. In the past decades, the study of autophagy in yeast and mammals has greatly increased our understanding for autophagy and its relationship with the diseases. In human, the regulation on autophagy levels can be used to prevent or treat neurodegenerative diseases, inflammatory diseases, tumors and various pathogenic microbial infections. However, in fish, the researches on autophagy and application are limited. Inflammation is a highly complex biological process, which is a natural defense response under the stimulation of ultraviolet, pathogen infection, oxidative stress and mechanical damage. Fish, as a lower vertebrate, has an incomplete acquired immune system. Innate immunity plays an important role in defensing against pathogen infection. Compared with higher vertebrate animals, although the researches on autophagy in fish cells were carried out lately, the great progress has been made in recent years on autophagy phenomenon, expression regulation of autophagy-related genes, and mechanism caused by pathogenic infection. As an important part of innate immunity, autophagy is involved in a variety of fish pathogenic infections, and fish diseases are usually accompanied by inflammatory reaction. In this review, we summarized the update findings in recent references on the autophagy and inflammatory response caused by pathogenic infection in fish, and the correlation between them, in order to deeply understand the correlation relationship between autophagy and inflammatory response in fish. This review could provide the guidance for understanding the immune mechanism of fish, and supply the foundation for developing new strategy to prevent and control fish disease.

Effects of SIRT1 on morphine-induced conditioned place preference in rats through CREB/BDNF pathway / 中国药理学通报

Aim To investigate the effect of microinjection of EX527, a selective SIRT1 antagonist, into the ventrolateral orbital cortex (VLO) on morphine-induced conditioned place preference (CPP), and to explore the role of CREB/BDNF in it. Methods The cannulas were implanted bilaterally in the VLO of rats by brain stereotaxis surgery, and the model of morphine-induced CPP was established. The behavioral experiment consisted of four stages:habituation (d 1), pre-test (d 2-4), conditioning training (d 5-14) and test (d 15). At the stage of conditioning training, EX527 (1 μL, 5 g·L

Self-assembly of CXCR4 antagonist peptide-docetaxel conjugates for breast tumor multi-organ metastasis inhibition

As a representative chemotherapeutic drug, docetaxel (DTX) has been used for breast cancer treatment for decades. However, the poor solubility of DTX limits its efficacy, and the DTX based therapy increases the metastasis risk due to the upregulation of C-X-C chemokine receptor type 4 (CXCR4) expression during the treatment. Herein, we conjugated CXCR4 antagonist peptide (CTCE) with DTX (termed CTCE-DTX) as an anti-metastasis agent to treat breast cancer. CTCE-DTX could self-assemble to nanoparticles, targeting CXCR4-upregulated metastatic tumor cells and enhancing the DTX efficacy. Thus, the CTCE-DTX NPs achieved promising efficacy on inhibiting both bone-specific metastasis and lung metastasis of triple-negative breast cancer. Our work provided a rational strategy on designing peptide-drug conjugates with synergistic anti-tumor efficacy.

Significance of anti-Jo-1 antibody's clinical stratification in idiopathic inflammatory myopathy and disease spectrum / 北京大学学报(医学版)

OBJECTIVE@#To investigate the significance of anti-histidyl tRNA synthetase (Jo-1) antibody in idiopathic inflammatory myopathies (IIM) and its diseases spectrum.@*METHODS@#We enrolled all the patients who were tested positive for anti-Jo-1 antibody by immunoblotting in Peking University People's Hospital between 2016 and 2022. And the patients diagnosed with anti-synthetase antibody syndrome (ASS) with negative serum anti-Jo-1 antibody were enrolled as controls. We analyzed the basic information, clinical characteristics, and various inflammatory and immunological indicators of the patients at the onset of illness.@*RESULTS@#A total of 165 patients with positive anti-Jo-1 antibody were enrolled in this study. Among them, 80.5% were diagnosed with connective tissue disease. And 57.6% (95/165) were diagnosed with IIM, including ASS (84/165, 50.9%), immune-mediated necrotizing myopathy (7/165, 4.2%) and dermatomyositis (4/165, 2.4%). There were 23.0% (38/165) diagnosed with other connective tissue disease, mainly including rheumatoid arthritis (11/165, 6.7%), undifferentiated connective tissue disease (5/165, 3.0%), interstitial pneumonia with autoimmune features (5/165, 3.0%), undifferentiated arthritis (4/165, 2.4%), Sjögren's syndrome (3/165, 1.8%), systemic lupus erythematosus (3/165, 1.8%), systemic vasculitis (3/165, 1.8%), and so on. Other cases included 3 (1.8%) malignant tumor patients, 4 (2.4%) infectious cases and so on. The diagnoses were not clear in 9.1% (15 /165) of the cohort. In the analysis of ASS subgroups, the group with positive serum anti-Jo-1 antibody had a younger age of onset than those with negative serum anti-Jo-1 antibody (49.9 years vs. 55.0 years, P=0.026). Clinical manifestations of arthritis (60.7% vs. 33.3%, P=0.002) and myalgia (47.1% vs. 22.2%, P=0.004) were more common in the ASS patients with positive anti-Jo-1 antibody. With the increase of anti-Jo-1 antibody titer, the incidence of the manifestations of arthritis, mechanic hands, Gottron sign and Raynaud phenomenon increased, and the proportion of abnormal creatine kinase and α-hydroxybutyric dehydrogenase index increased in the ASS patients. The incidence of myalgia and myasthenia were significantly more common in this cohort when anti-Jo-1 antibody-positive ASS patients were positive for one and more myositis specific antibodies/myositis associated autoantibodies (P < 0.05).@*CONCLUSION@#The disease spectrum in patients with positive serum anti-Jo-1 antibody includes a variety of diseases, mainly ASS. And anti-Jo-1 antibody can also be found in many connective tissue diseases, malignant tumor, infection and so on.

Mechanical effects of needle texture on acupoint tissue / 中西医结合学报

OBJECTIVE@#This study aims to clarify how the stimulation of acupuncture points is achieved by needles with different surface texture during acupuncture; it also seeks to lessen injury at the insertion site and increase the therapeutic efficacy of acupuncture, by simulating the mechanical effects of various needle surface patterns on Zusanli (ST36) without changing the radius of acupuncture needles.@*METHODS@#Five acupuncture needle models with different surface patterns, including the smooth needle, the lined needle, the ringed needle, the left-hand threaded needle and the right-hand threaded needle, and a layered model of the Zusanli acupoint were used to investigate how to reduce tissue damage and increase stimulation during acupuncture treatment. Puncturing of the skin as well as lifting-inserting and twisting needle manipulations were simulated using these models, and the degree of damage and force of stimulation caused by the acupuncture needles with different surface patterns during acupuncture were compared.@*RESULTS@#The smooth needle and the lined needle caused the least tissue damage during insertion, while the left-hand threaded and the right-hand threaded needles caused the most damage. The ringed needle, the left-hand threaded needle and the right-hand threaded needle stimulated the acupoint tissue more during lifting-inserting manipulations, while the lined needle and the smooth needle produced less stimulation. The stimulation of the lined needle on the acupoint tissue was the largest during twisting manipulation, whereas the left-hand threaded needle and the right-hand threaded needle had smaller effects. In lifting-inserting and twisting manipulations, both the left-hand threaded needle and right-hand threaded needle provided more stimulation, but the torsion direction in which they produced better stimulation was the opposite.@*CONCLUSION@#According to the simulation results, the ringed pattern enhances stimulation best in the lifting-inserting manipulation, whereas the lined pattern enhances stimulation best in the twisting manipulation. Both the right-hand and left-hand thread patterns have certain enhancing effects in these two operations. Taking the geometric properties of the pattern into account, the left-hand thread pattern and the right-hand thread pattern have the geometric characteristics of both the lined pattern and the ringed pattern. To conclude, a pattern perpendicular to the movement direction during the acupuncture manipulation creates more stimulation. These results have significance for future needle design.

Highly sensitive H2O2-scavenging nano-bionic system for precise treatment of atherosclerosis

In atherosclerosis, chronic inflammatory processes in local diseased areas may lead to the accumulation of reactive oxygen species (ROS). In this study, we devised a highly sensitive H2O2-scavenging nano-bionic system loaded with probucol (RPP-PU), to treat atherosclerosis more effectively. The RPP material had high sensitivity to H2O2, and the response sensitivity could be reduced from 40 to 10 μmol/L which was close to the lowest concentration of H2O2 levels of the pathological environment. RPP-PU delayed the release and prolonged the duration of PU in vivo. In Apolipoprotein E deficient (ApoE‒/‒) mice, RPP-PU effectively eliminated pathological ROS, reduced the level of lipids and related metabolic enzymes, and significantly decreased the area of vascular plaques and fibers. Our study demonstrated that the H2O2-scavenging nano-bionic system could scavenge the abundant ROS in the atherosclerosis lesion, thereby reducing the oxidative stress for treating atherosclerosis and thus achieve the therapeutic goals with atherosclerosis more desirably.

AIM: To observe the therapeutic effect of the diquafosol sodium combined with intense pulsed light(IPL)on meibomian gland dysfunction(MGD)dry eye after refractive surgery.METHODS:A total of 64 patients(128 eyes)with MGD dry eye diagnosed within 6mo after laser corneal refractive surgery in our hospital from March 2021 to December 2021 were selected. They were randomly divided into control group and experimental group. A total of 33 patients(66 eyes)in the control group were treated with sodium hyaluronate combined with IPL, and 31 patients(62 eyes)in the experimental group were treated with diquafosol sodium combined with IPL. Ocular symptom scores were performed before each IPL treatment in both groups to examine non-invasive tear breakup time(NIBUT), tear meniscus height, lipid layer grade of tear film, meibomian gland deletion rate and uncorrected visual acuity.RESULTS:After IPL treatment, ocular symptom scores and meibomian gland deletion rate score of two groups were decreased continuously. NIBUT, tear meniscus height and lipid layer grade of tear film were increased continuously, and there was no significant change in uncorrected visual acuity. NIBUT of patients in the experimental group was better than that in the control group before the third IPL treatment(6.24±0.27s vs. 5.51±0.24s, P=0.046).CONCLUSIONS:Both diquafosol sodium and sodium hyaluronate combined with IPL showed good therapeutic effect on MGD dry eye, but there was no significant difference in the short-term efficacy between the two groups.

The status of medication review in addressing drug-related problems of elderly patients in the community / 中国药房

With the increasing aging of our population， the incidence of drug-related problems among elderly patients in the community is gradually increasing. Drug-related problems can lead to an increased incidence of adverse health outcomes such as falls and frailty in elderly patients in the community. Medication review is one of the effective means of addressing drug-related problems. The medication review models in Europe and the United States have been developed for decades to address drug-related problems； medication review model in the United Kingdom focuses on the management of drug therapy for elderly patients in aged care facilities， while the medication review models in the United States and Australia have a broader scope（covering all elderly patients in the community）， and the frequency of medication reviews in the United States and Australia are clearer and more standardized. Compared with the above countries， China’s medication review model has a late start. Our country can learn from the advanced experience of the United Kingdom， the United States， Australia and other countries， actively explore and build a drug review model suitable for China’s national conditions， so as to improve the health level of elderly patients in the community and save social public medical resources.

Study on pharmaceutical care model for drug-related problems in elderly patients based on comprehensive medication management review / 中国药房

OBJECTIVE To explore the pharmaceutical care model for elderly patients with drug-related problems （DRPs） based on the comprehensive medication management review （CMMR）， and to observe the effect of pharmaceutical care under the model. METHODS The pharmaceutical care new model for elderly patients was established by concerning CMMR guidelines in Australia. In other words， clinical pharmacists receive medical care through referral by health practitioners and active consultation by patients or their caregivers. Visits were made by a combination of face-to-face and telephone interviews. Follow-up was carried out in the form of outpatient follow-up， telephone follow-up， appointment， and home guidance to know about the treatment of DRPs by healthcare practitioners or patients.Under this model， the occurrence status and classification of DRPs in elderly patients were studied through cross-sectional investigation. The effect of pharmaceutical care was evaluated from the aspects of hospitalization rate， adverse drug reaction （ADR） incidence，medication compliance， the number of medications， blood lipid level， etc.， through self-before-after comparison. RESULTS In this study， a patient-centered， evaluation-intervention-reevaluation closed-loop pharmaceutical care model was formed. Among 317 study subjects， the average number of DRPs was 1.03 （0-7） cases. Compared before and after the intervention， the number of drug types increased from 2.00（0.00，3.00） to 2.00（1.00，3.00）， but the level of low-density lipoprotein cholesterin in patients decreased from 3.48 （2.58， 4.29） mmol/L to 3.11 （2.29，3.81） mmol/L （P＜0.05）. There was no statistical significance in hospitalization rate， ADR incidence within or medication compliance. CONCLUSIONS CMMR-based pharmaceutical care model can effectively identify and manage the patients’ DRPs and reduce the level of blood lipid.

Thoughts of treatment of tumor diseases based on toxic pathogen theory / 中国中药杂志

The toxic pathogen theory, an important part of the theories of traditional Chinese medicine(TCM), began in the Qin and Han dynasties, formed in the Jin, Sui, Tang, and Song dynasties, developed rapidly in the Ming and Qing dynasties, and conti-nued to develop in contemporary times based on the achievements of its predecessors. The continuous exploration, practice, and inheri-tance of many medical practitioners over the generations have facilitated the enrichment of its connotation. The toxic pathogen is violent, fierce, dangerous, prolonged, rapid in transmission, easy to hurt the internal organs, hidden, and latent, with many changes, and it is closely related to the development of tumor diseases. TCM has a history of thousands of years in the prevention and treatment of tumor diseases. It is gradually realized that the etiology of tumor is mainly attributed to the deficiency of healthy Qi and excess of to-xic pathogen, and the struggle between healthy Qi and toxic pathogen runs through the whole course of tumor, with the deficiency of healthy Qi as the prerequisite and the invasion of toxic pathogen as the root of the occurrence. The toxic pathogen has a strong carcinogenic effect and is involved in the whole process of tumor development, which is closely related to the malignant behaviors of tumors, including proliferation, invasion, and metastasis. This study discussed the historical origin and modern interpretation of the toxic pathogen theory in the prevention and treatment of tumors, with aims of sorting out the theoretical system based on the toxic pathogen theory in the treatment of tumor diseases, and illustrating the importance of the toxic pathogen theory in the treatment of tumors in the context of modern research on pharmacological mechanisms and the development and marketing of relevant anti-tumor Chinese medicinal preparations.

Maxent modeling for predicting the global potential distribution of talaromycosis marneffei / 中国热带医学

@#Abstract: Objective　To predict the potential distribution of talaromycosis marneffei (TSM) and analyze its driving factors, so as to provide evidence for the surveillance and prevention of this disease. Methods　The data of all laboratory-confirmed, non-duplicating TSM published in the English and Chinese literature from the first case in January 1964 to December 2018 was collected. A Maxent ecology model using environmental variables, Rhizomys distribution and HIV/AIDS epidemic was developed to forecast ecological niche of TSM worldwide, as well as identify the driving factors. Results　A total of 705 articles (477 in Chinese and 228 in English) were obtained during the study period. After excluding imported cases, a total of 100 foci information were included in the model. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was 0.997 for the training set and 0.991 for the test set. Maxent model revealed that Rhizomys distribution, mean temperature of warmest quarter, precipitation of wettest month, HIV/AIDS epidemic and mean temperature of driest quarter were the top 5 important variables affecting TSM distribution. In addition to identifying traditional TSM endemic areas (South of the Yangtze River in China, Southeast Asian, North and Northeast India), other potential endemic areas were also identified, including parts of the North of the Yangtze River, Central America, West Coast of Africa, East Coast of South America, the Korean Peninsula and Japan. Conclusion　Our finding has discovered hidden high-risk areas and provided insights about driving factors of TSM distribution, which will help inform surveillance strategies and improve the effectiveness of public health interventions against TM infections.

Application practice of drug clinical comprehensive evaluation thinking in management of temporary drug purchase in hospital / 中国药房

OBJECTIVE To explore the construction of a new scientific management model for temporary drug purchase，and to provide a reference for hospitals to improve the level of rational drug use. METHODS Guided by clinical diagnosis and treatment needs and patient medication safety， our hospital carried out the whole process management practice of temporarily purchased drugs by optimizing the review process， creating a review team， formulating pre-audit and post follow-up evaluation standards based on comprehensive drug evaluation， and evaluated the practice effect through the number of temporary purchase applications， implementation rate， drug structure optimization and other indicators. RESULTS Since January 2021， our hospital had implemented a new mode of temporary drug purchase management. By December 2022， clinical pharmacists had reviewed 111 temporary drug procurement applications， effectively intercepted 13 irrational drug use applications （11.71%）， reduced the overall implementation rate of temporary drug procurement by 8.36%，and proposed five batches of drug structure optimization suggestions； 24 drugs were successively introduced such as camrelizumab，sorafenib，busulfan. After optimizing the management mode，the number of temporary drug procurement applications decreased by more than half from 133 in 2019 and 138 in 2020 to 66 in 2021 and 45 in 2022. CONCLUSIONS The model is helpful to optimize the hospital drug catalog， strengthen rational drug use，ensure the safety of patients’ drug use， and fully reflects the professional value of clinical pharmacists in hospital pharmacy management and rational drug use.

Transcriptional analysis on biomarkers of liver injury induced by anti-tuberculosis drugs / 上海预防医学

ObjectiveThe study utilized human transcriptome microarray to explore biomarkers for diagnosing drug-induced liver injury （DILI） caused by anti-tuberculosis drugs. MethodsA 6-month follow-up study was conducted on 152 patients treated with anti-tuberculosis drugs in designated hospitals in Shanghai. The blood samples were collected at the 0， 2， 4， 8， 12 and 24 weeks after treatment. According to the clinical biochemical indicators， the research subjects were divided into DILI cases （34 cases） and Control cases （118 cases）. Single factor analysis was conducted on the influencing factors between the two groups. In a 1∶1 matched DILI-control study， RNA samples of 13 pairs of cases were sequenced by the whole transcript expression mRNA array. Differentially expressed genes （DEGs） were screened by Hotelling's T2 value sequencing and the expression trend analysis of genes by STEM （short-time series expression miner）， and the functional enrichment and pathway analysis of DEGs were carried out. ResultsIn total 152 clinical cases， weight of patients was a risk factor for the occurrence of hepatotoxicity caused by anti-tuberculous drugs. Based on the analysis results of mRNA array， 513 DEGs were screened by Hotelling's T2 value sequencing method， which were enriched in 32 annotations of GO （Gene Ontology） analysis and 10 pathways of KEGG （Kyoto encyclopedia of genes and genomes） analysis. One differential expression pattern was screened by STEM， which was enriched in 2 biological process notes of GO. Among them， the key genes AIM2， CD86， CXCL10 and non-coding RNAs SCARNA10， SNHG10 and SNORD105 are potential biomarkers of DILI caused by anti-tuberculosis drugs. ConclusionIn this research for biomarkers conducted on cases with liver injury caused by anti-tuberculosis drugs， biological pathways associated with hepatotoxicity are identified and a series of key genes related with drug-induced liver injury are found， which provides the basis for mechanism study and searching for earlier and more sensitive biomarkers.
