Taohong Siwu Decoction: a classical Chinese prescription for treatment of orthopedic diseases.

The pathogenesis of orthopedic diseases is intimately linked to blood stasis, frequently arising from damage to primary and secondary blood channels. This disruption can lead to "blood leaving the meridians" or Qi stagnation, resulting in blood stasis syndrome. Taohong Siwu Decoction (THSWD) is a renowned classical Chinese medicinal formula extensively used to promote blood circulation and mitigate blood stasis. Clinical studies have demonstrated its significant therapeutic effects on various orthopedic conditions, particularly its anti-inflammatory and analgesic properties, as well as its efficacy in preventing deep vein thrombosis post-surgery. Despite these findings, research on THSWD remains fragmented, and its interdisciplinary impact is limited. This review aims to provide a comprehensive evaluation of the efficacy and pharmacological mechanisms of THSWD in treating common orthopedic diseases. Additionally, we employ bibliometric analysis to explore research trends and hotspots related to THSWD. We hope this review will enhance the recognition and application of THSWD in orthopedic treatments and guide future research into its pharmacological mechanisms.

Development and validation of a scoring system to predict the mortality of hospitalized patients with SARS-CoV-2 Omicron: a nationwide, multicentre study.

BACKGROUND: The Omicron variant broke out in China at the end of 2022, causing a considerable number of severe cases and even deaths. The study aimed to identify risk factors for death in patients hospitalized with SARS-CoV-2 Omicron infection and to establish a scoring system for predicting mortality. METHODS: 1817 patients were enrolled at eight hospitals in China from December 2022 to May 2023, including 815 patients in the training group and 1002 patients in the validation group. Forty-six clinical and laboratory features were screened using LASSO regression and multivariable logistic regression. RESULTS: In the training set, 730 patients were discharged and 85 patients died. In the validation set, 918 patients were discharged and 84 patients died. LASSO regression identified age, levels of interleukin (IL) -6, blood urea nitrogen (BUN), lactate dehydrogenase (LDH), and D-dimer; neutrophil count, neutrophil-to-lymphocyte ratio (NLR) as associated with mortality. Multivariable logistic regression analysis showed that older age, IL-6, BUN, LDH and D-dimer were significant independent risk factors. Based on these variables, a scoring system was developed with a sensitivity of 83.6% and a specificity of 83.5% in the training group, and a sensitivity of 79.8% and a sensitivity of 83.0% in the validation group. CONCLUSIONS: A scoring system based on age, IL-6, BUN, LDH and D-dime can help clinicians identify patients with poor prognosis early.

A case of Elizabethkingia meningoseptica septicemia. / 脑膜脓毒性伊丽莎白金菌败血症一例.

A 82-year-old man was admitted to hospital with fever, unresponsiveness, elevated hypersensitive C-reactive protein and neutrophile granulocyte. Ceftriaxone was administrated by intravenous dripping in the emergency room, but the effect was not satisfactory. Following his admission to the ward, cefoperazone sulbactam were given. Elizabethkingia meningoseptica was identified by blood culture and further confirmed by 16S rRNA sequencing. The lumbar puncture showed that cerebrospinal fluid pressure was 80 mmH2O (1 mmH2O=0.0098 kPa) and biochemical results were normal. After 11 days of cefoperazone sulbactam treatment, the patient was discharged with negative blood culture. The hypersensitive C-reactive protein and neutrophile granulocyte had also declined. The patient received levofloxacin tablets for anti-infection treatment for 14 d after discharge. No signs of infection were observed in three months' following up.

Bloodstream infection, peritonitis, and pneumonia caused by Pasteurella multocida in a patient with liver cirrhosis despite no animal contact: case report and literature review.

Pasteurella multocida is an opportunistic pathogen. Previously reported infections associated with P. multocida have often been linked to contact with cats, dogs, and other animals. Cases of systemic multiple-site infections following P. multocida infection are rare. This case study presents a 49-year-old middle-aged man with post-hepatitis B cirrhosis and no history of animal contact. The patient was admitted with symptoms of fever accompanied by diarrhea, abdominal distension, and cough. Blood tests showed elevated levels of CRP, PCT, and IL-6, and blood culture revealed the growth of P. multocida. CT scans revealed a large amount of abdominal effusion, a small amount of pleural effusion, and pulmonary infection foci. The patient's condition improved after successive administration of ceftriaxone and levofloxacin to fight the infection, and abdominal puncture and drainage. Multiple-site infections caused by P. multocida are rarely encountered in patients with liver cirrhosis but without animal contact, which could be regarded as serious conditions warranting careful attention in terms of clinical diagnosis and treatment.

An Individualized Nomogram for Predicting Mortality Risk of Septic Shock Patients During Hospitalization: A ten Years Retrospective Analysis.

Purpose: We intend to develop a nomogram for predicting the mortality risk of hospitalized septic shock patients. Patients and Methods: Data were collected from patients hospitalized with septic shock in Affiliated Dongyang Hospital of Wenzhou Medical University in China, over 10 years between January 2013 and January 2023. The eligible study participants were divided into modeling and validation groups. Factors independently related to the mortality in the modeling group were obtained by stepwise regression analysis. A logistic regression model and a nomogram were built. The model was evaluated based on the discrimination power (the area under the curve of the receiver operating characteristic, AUC), the calibration degree and decision curve analysis. In the validation group, the discrimination powers of the logistic regression model, the sequential organ failure assessment (SOFA) scoring model and machine learning model were compared. Results: A total of 1253 patients, including 878 patients in the modeling group and 375 patients in the validation group, were included in this study. Age, respiratory failure, serum cholinesterase, lactic acid, blood phosphorus, blood magnesium, total bilirubin, and pH were independent risk factors related to the mortality risk of septic shock. The AUCs of the prediction model for the modeling and validation groups were 0.881 and 0.868, respectively. The models had a good calibration degree and clinical applicability. The AUC of the SOFA model for the validation population was 0.799, significantly lower than that of our model. The AUCs of the random forest and ensemble models were 0.865 and 0.863, respectively, comparable to that of our logistical prediction model. Conclusion: The model established in this study can effectively predict the mortality risk in patients hospitalized with septic shock. Thus, the model could be used clinically to determine the best therapy or management for patients with septic shock.

Managing Comorbidities, Determinants and Disability at Start and End of TB Treatment under Routine Program Conditions in China.

Many patients with tuberculosis (TB) have comorbidities, risk determinants and disability that co-exist at diagnosis, during and after TB treatment. We conducted an observational cohort study in 11 health facilities in China to assess under routine program conditions (i) the burden of these problems at the start and end of TB treatment and (ii) whether referral mechanisms for further care were functional. There were 603 patients registered with drug-susceptible TB who started TB treatment: 84% were symptomatic, 14% had diabetes, 14% had high blood pressure, 19% smoked cigarettes, 10% drank excess alcohol and in 45% the 6 min walking test (6MWT) was abnormal. Five patients were identified with mental health disorders. There were 586 (97%) patients who successfully completed TB treatment six months later. Of these, 18% were still symptomatic, 12% had diabetes (the remainder with diabetes failed to complete treatment), 5% had high blood pressure, 5% smoked cigarettes, 1% drank excess alcohol and 25% had an abnormal 6MWT. Referral mechanisms for the care of comorbidities and determinants worked well except for mental health and pulmonary rehabilitation for disability. There is need for more programmatic-related studies in other countries to build the evidence base for care of TB-related conditions and disability.

Development of a Nomogram for Predicting Mortality Risk in Sepsis Patients During Hospitalization: A Retrospective Study.

Purpose: We attempted to establish a model for predicting the mortality risk of sepsis patients during hospitalization. Patients and Methods: Data on patients with sepsis were collected from a clinical record mining database, who were hospitalized at the Affiliated Dongyang Hospital of Wenzhou Medical University between January 2013 and August 2022. These included patients were divided into modeling and validation groups. In the modeling group, the independent risk factors of death during hospitalization were determined using univariate and multi-variate regression analyses. After stepwise regression analysis (both directions), a nomogram was drawn. The discrimination ability of the model was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve, and the GiViTI calibration chart assessed the model calibration. The Decline Curve Analysis (DCA) was performed to evaluate the clinical effectiveness of the prediction model. Among the validation group, the logistic regression model was compared to the models established by the SOFA scoring system, random forest method, and stacking method. Results: A total of 1740 subjects were included in this study, 1218 in the modeling population and 522 in the validation population. The results revealed that serum cholinesterase, total bilirubin, respiratory failure, lactic acid, creatinine, and pro-brain natriuretic peptide were the independent risk factors of death. The AUC values in the modeling group and validation group were 0.847 and 0.826. The P values of calibration charts in the two population sets were 0.838 and 0.771. The DCA curves were above the two extreme curves. Moreover, the AUC values of the models established by the SOFA scoring system, random forest method, and stacking method in the validation group were 0.777, 0.827, and 0.832, respectively. Conclusion: The nomogram model established by combining multiple risk factors could effectively predict the mortality risk of sepsis patients during hospitalization.

First case of bloodstream infection caused by NDM-positive Escherichia hermannii.

BACKGROUND: Escherichia hermannii (E. hermanni) is always accompanied by other bacterial infections in humans. In previous reports, most E. hermannii-related infections were caused by sensitive strains. Here, for the first time, we report the case of a patient with New Delhi metallo-ß-lactamase (NDM)-positive E. hermannii bloodstream infection. CASE PRESENTATION: The patient was a 70-year-old male admitted to our hospital due to a 4-day fever, with a history of malignant tumor, liver cirrhosis, and chronic obstructive pulmonary disease. After admission, his blood culture tested positive for E. hermannii. The drug resistance analysis showed positive for NDM resistance, with susceptibility to aztreonam, levofloxacin, and amikacin. The blood culture turned negative after 8 days of aztreonam treatment. The patient's symptoms improved, and he was discharged after 14 days of hospitalization. CONCLUSIONS: This is the first report of a bloodstream infection caused by an NDM-positive E. hermannii strain. The anti-infection regimen used in this case provides a new reference regimen for clinical practice.

Randomized control study of the use of faropenem for treating patients with pulmonary tuberculosis.

OBJECTIVES: Faropenem has antituberculosis activity in vitro but its utility in treating patients with tuberculosis (TB) is unclear. METHODS: We conducted an open-label, randomized trial in China, involving newly diagnosed, drug-susceptible pulmonary TB. The control group was treated with the standard 6-month regimen. The experimental group replaced ethambutol with faropenem for 2 months. The primary outcome was the treatment success rate after 6 months of treatment. Noninferiority was confirmed if the lower limit of a 95% one-sided confidence interval (CI) of the difference was greater than -10%. RESULTS: A total of 227 patients eligible for the study were enrolled in the trial group and the control group in a ratio of 1:1. Baseline characteristics of participants were similar in both groups. In the modified intention-to-treat population, 88.18% of patients in the faropenem group achieved treatment success, and 85.98% of those in the control group were successfully treated, with a difference of 2.2% (95% CI, -6.73-11.13). In the per-protocol population, treatment success was 96.04% in the faropenem group and 95.83% in the control group, with a difference of 2.1% (95% CI, -5.31-5.72). The faropenem group showed noninferiority to the control group in the 6-month treatment success rates. The faropenem group had significantly fewer adverse events (P <0.01). CONCLUSIONS: Our study proved that oral faropenem regimen can be used for the treatment of TB, with fewer adverse events. (Chinese Clinical Trial Registry, ChiCTR1800015959).

A case of severe leptospirosis with Jarisch-Herxheimer reaction presenting as respiratory failure.

Background: Leptospirosis is a widespread zoonotic disease caused by pathogenic Leptospira spp. The treatment of penicillin or tetracycline can cause a Jarisch-Herxheimer reaction (JHR), which can lead to acute respiratory distress syndrome (ARDS) and multi-organ failure in severe cases. The overall course of evolution and imaging features of a JHR exacerbation of leptospirosis have rarely been reported. Case presentation: We present a case of leptospirosis complicated by pulmonary alveolar hemorrhage and a Jarisch-Herxheimer reaction (JHR) that required respiratory and vasopressor support. This case demonstrates a well-defined course of evolution of JHR and the imaging features. Conclusions: Leptospirosis is easily misdiagnosed in some sporadic areas, and JHR complicates its management. Early diagnosis and appropriate treatment can reduce the mortality of severe leptospirosis with JHR.

Case Report: The First Case of Bloodstream Infection Complicated with Psoas Abscess and Pulmonary Infection Caused by Aggregatibacter aphrophilus in China.

Aggregatibacter aphrophilus is part of the normal flora in the oropharynx and upper respiratory tract, which causes invasive bacteremia in rare cases. However, the culture and identification of Aggregatibacter aphrophilus are challenging, hence easily misdiagnosed or undetected in clinical practice. In this case, a 73-year-old male patient was admitted to the hospital with a fever and right hip pain. Routine blood and C-reactive protein tests showed abnormal inflammatory markers. Positive blood culture revealed the presence of Aggregatibacter aphrophilus through mass spectrometry. The computed tomography examination further revealed the presence of psoas abscess, pulmonary infection, and pleural effusion, which was relieved by ceftriaxone combined with levofloxacin therapy, the drainage of psoas abscess and pleural effusion. Therefore, since multiple anatomic sites infection, including bloodstream, psoas abscess and pulmonary infection caused by Aggregatibacter aphrophilus, is rare, sufficient attention should be paid to its clinical diagnosis and treatment.

Aortic Involvement in Disseminated Tuberculosis - Challenges Beyond the Diagnosis.

Tuberculous aortitis (TA) is a rare disease with a high mortality rate. Aortic pseudoaneurysm is the most common vascular pattern of TA, and isolated arterial wall thickening and arterial stenosis can also be seen in TA. We report two cases of disseminated tuberculosis involving the aorta with clinical improvement after treatment. One patient who had an aortic ulcer and intermural hematoma received anti-tuberculosis along with steroids therapy. The other patient, who developed a tubercular abdominal aortic pseudoaneurysm during anti-tuberculosis therapy, successfully received endovascular stent implantation. Clinicians should be aware that TA should be considered in patients with aortitis and active tuberculosis.

Tofacitinib for the treatment of rheumatoid arthritis: a real-world study in China.

Tofacitinib has only been available in China for 2 years to treat rheumatoid arthritis (RA). Our purpose was to compare real-world effectiveness of tofacitinib with that of disease-modifying anti-rheumatic drugs (DMARDs) in Chinese patients with RA. The records of patients with RA treated at Guangdong Provincial People's Hospital between July 2017 and September 2019 were retrospectively reviewed. Patients were divided into those treated with tofacitinib, biological DMARDs (bDMARDs), and conventional synthetic DMARDs (csDMARDs). Clinical disease activity index (CDAI), simplified disease activity index (SDAI), health assessment questionnaire-disability index (HAQ-DI), visual analog scale (VAS) pain score, patient global assessment of disease activity (PtGA), physician global assessment of disease activity (PhGA), and swollen joint and tender joint count were compared among the groups up to 12 months of treatment. A total of 150 patients were included: 63 were treated with tofacitinib, 48 with bDMARDs, and 39 with csDMARDs. Tofacitinib was first-line treatment in 26.98% of patients, second-line treatment in 49.21%, and third-line treatment in 26.98%. Patients in the tofacitinib group had significantly higher disease duration (6.11 ± 6.97 years) than those in the other groups. All disease indices in the three groups decreased with time, indicating improvement of symptoms, with no differences among the groups at 12 months. Tofacitinib appeared to improve symptoms more rapidly than other treatments; however, differences in disease indices were not significant. This real-world study suggests that tofacitinib is rapidly effective and that the effects are sustained after 12 months in Chinese patients with RA.

Study on the Chemical Constituents and Anti-Migraine Activity of Supercritical CO2 Extracts of Zanthoxylum schinifolium.

Background: Zanthoxylum schinifolium is a common herbal medicine in Southwest China. It is also a condiment commonly used in many families. In Chinese folk medicine, Z. schinifolium is considered to have the effect of relieving migraine, but there is no modern evidence on its anti-migraine mechanism. Objective: The aim of this study was to investigate the chemical constituents of the supercritical carbon dioxide extracts of Z. schinifolium (CO2-ZSE) and its effects on migraine animals. Materials and Methods: Supercritical CO2 extraction technology was applied to extract the dried fruit of Z. schinifolium, and the chemical components were determined by gas chromatography-mass spectrometry (GC-MS). Two migraine animal models were established by subcutaneous injection of nitroglycerin (NTG) and reserpine, respectively, to further evaluate the therapeutic effect of CO2-ZSE and explore its mechanism. On the basis of the experimental results, the therapeutic effects of linalool in different dosages and different ways of administration on NTG-induced migraine rats have been further investigated. Results: About 125 peaks were detected in CO2-ZSE, and the relative content of linalool was 74.16%. CO2-ZSE decreased the number of head-scratching significantly and the levels of serum nitric oxide (NO), endothelin-1 (ET-1), calcitonin gene-related peptide (CGRP), interleukin-1ß (IL-1ß), nuclear factor kappa B (NF-κB) p65, and inhibitor of kappa B alpha (IκBα), and increased the level of 5-hydroxytryptamine (5-HT). Linalool has the potential to reduce the frequency of scratching the head and the expressions of NO, ET-1, and CGRP in NTG-induced migraine rats. Conclusion: CO2-ZSE has a definite therapeutic effect on migraine by affecting the expression of vasomotor factors and the inflammatory pathway. Linalool has been proven to be the main effective substance against migraine. These findings provide scientific basis for the development of effective and simple migraine therapy.

The Application of Whole-Exome Sequencing in Patients With FUO.

BACKGROUND: Fever of unknown origin (FUO) is still a challenge for clinicians. Next-generation sequencing technologies, such as whole exome sequencing (WES), can be used to identify genetic defects in patients and assist in diagnosis. In this study, we investigated the application of WES in individuals with FUO. METHODS: We performed whole-exome sequencing on 15 FUO patients. Clinical information was extracted from the hospital information system. RESULTS: In 7/15 samples, we found positive results, including potentially causative mutations across eight different genes: CFTR, CD209, IRF2BP2, ADGRV 1, TYK2, MEFV, THBD and GATA2. CONCLUSIONS: Our results show that whole-exome sequencing can promote the genetic diagnosis and treatment of patients with FUO.

Nanoparticle-based Drug Delivery Systems for Targeted Epigenetics Cancer Therapy.

This review summarizes the epigenetic mechanisms of deoxyribonucleic acid (DNA) methylation, histone modifications in cancer and the epigenetic modifications in cancer therapy. Due to their undesired side effects, the use of epigenetic drugs as chemo-drugs in cancer therapies is limited. The drug delivery system opens a door for minimizing these side effects and achieving greater therapeutic benefits. The limitations of current epigenetic therapies in clinical cancer treatment and the advantages of using drug delivery systems for epigenetic agents are also discussed. Combining drug delivery systems with epigenetic therapy is a promising approach to reaching a high therapeutic index and minimizing the side effects.

Retrospective analysis of patients with non-tuberculous mycobacteria from a primary hospital in Southeast China.

To achieve a comprehensive understanding of the characteristics of patients with non-tuberculous mycobacteria (NTM), patients with NTM between January 2016 and June 2019 were recruited from a primary hospital. NTM were identified based on the MBP64 protein assay. The clinical records and laboratory assay results were retrospectively reviewed. A total of 204 patients with NTM were included in the final analysis. The patients with multiple isolations were more likely accompanied with chronic obstructive pulmonary disease (COPD) (p = 0.029) and arthritis (p = 0.049), but showed a lower percentage of positive T-spot results (p = 0.022). In addition, patients with multiple isolations showed a higher rate of positive acid-fast staining results and their symptom duration was more likely longer than 30 days (p = 0.019). Patients with a positive response in T-spot assay showed a higher proportion of nodular manifestation on computed tomography (CT) than those with a negative response. Compared with male patients with NTM, female patients showed lower rates of positive acid-fast staining results (p = 0.03), but were more likely accompanied with COPD (p < 0.0001). The positive acid-fast staining results were closely associated with pulmonary cavities and tuberculosis antibody. Patients with different NTM isolation frequencies were closely associated with coexisting diseases and examination results.
