Neoadjuvant radiohormonal therapy for oligo-metastatic prostate cancer: safety and efficacy outcomes from an open-label, dose-escalation, single-center, phase I/II clinical trial / 医学前沿

To evaluate the safety and efficacy of neoadjuvant radiohormonal therapy for oligometastatic prostate cancer (OMPC), we conducted a 3 + 3 dose escalation, prospective, phase I/II, single-arm clinical trial (CHiCTR1900025743), in which long-term neoadjuvant androgen deprivation was adopted 1 month before radiotherapy, comprising intensity modulated radiotherapy to the pelvis, and stereotactic body radiation therapy to all extra-pelvic bone metastases for 4-7 weeks, at 39.6, 45, 50.4, and 54 Gy. Robotic-assisted radical prostatectomy was performed after 5-14 weeks. The primary outcome was treatment-related toxicities and adverse events; secondary outcomes were radiological treatment response, positive surgical margin (pSM), postoperative prostate-specific antigen (PSA), pathological down-grading and tumor regression grade, and survival parameters. Twelve patients were recruited from March 2019 to February 2020, aging 66.2 years in average (range, 52-80). Median baseline PSA was 62.0 ng/mL. All underwent RARP successfully without open conversions. Ten patients recorded pathological tumor down-staging (83.3%), and 5 (41.7%) with cN1 recorded negative regional lymph nodes on final pathology. 66.7% (8/12) recorded tumor regression grading (TRG) -I and 25% (3/12) recorded TRG-II. Median follow-up was 16.5 months. Mean radiological progression-free survival (RPFS) was 21.3 months, with 2-year RPFS of 83.3%. In all, neoadjuvant radiohormonal therapy is well tolerated for oligometastatic prostate cancer.

Exploration and example interpretation of real-world herbal prescription classification based on similarity matching algorithm / 中国中药杂志

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

Clinical efficacy and long-term immunogenicity of an early triple dose regimen of SARS-CoV-2 mRNA vaccination in cancer patients

INTRODUCTION@#Three doses of SARS-CoV-2 mRNA vaccines have been recommended for cancer patients to reduce the risk of severe disease. Anti-neoplastic treatment, such as chemotherapy, may affect long-term vaccine immunogenicity.@*METHOD@#Patients with solid or haematological cancer were recruited from 2 hospitals between July 2021 and March 2022. Humoral response was evaluated using GenScript cPASS surrogate virus neutralisation assays. Clinical outcomes were obtained from medical records and national mandatory-reporting databases.@*RESULTS@#A total of 273 patients were recruited, with 40 having haematological malignancies and the rest solid tumours. Among the participants, 204 (74.7%) were receiving active cancer therapy, including 98 (35.9%) undergoing systemic chemotherapy and the rest targeted therapy or immunotherapy. All patients were seronegative at baseline. Seroconversion rates after receiving 1, 2 and 3 doses of SARS-CoV-2 mRNA vaccination were 35.2%, 79.4% and 92.4%, respectively. After 3 doses, patients on active treatment for haematological malignancies had lower antibodies (57.3%±46.2) when compared to patients on immunotherapy (94.1%±9.56, P<0.05) and chemotherapy (92.8%±18.1, P<0.05). SARS-CoV-2 infection was reported in 77 (28.2%) patients, of which 18 were severe. No patient receiving a third dose within 90 days of the second dose experienced severe infection.@*CONCLUSION@#This study demonstrates the benefit of early administration of the third dose among cancer patients.

National Institute of Health Stroke Scale was associated with the immediate and long-term prognosis of patients with acute ischemic stroke treated with intravenous thrombolysis

OBJECTIVE: The objective of this study was to examine whether the National Institute of Health Stroke Scale was associated with the short- and long-term prognosis of patients with acute ischemic stroke treated with intravenous thrombolysis. METHODS: A total of 247 patients with acute ischemic stroke admitted to the hospital from April 2019 to October 2020 were retrospectively selected as study subjects, and the immediate and long-term prognosis after thrombolysis was assessed using the modified Rankin Scale and divided into good prognosis group (119 cases) and poor prognosis group (128 cases) based on the effect of thrombolysis. Both groups were treated with alteplase, the National Institute of Health Stroke Scale of the two groups was compared, and the factors affecting the prognosis of acute ischemic stroke were analyzed. RESULTS: After intravenous thrombolysis, 24 h, and 7 days of treatment, the National Institute of Health Stroke Scale in the poor prognosis group was higher than those of patients in the good prognosis group, and the differences were statistically significant (p<0.05). The results of the multivariate analysis suggested that National Institute of Health Stroke Scale before treatment was an independent factor associated with the 3-month (OR: 1.068, 95%CI 1.015-1.123, p=0.011) and long-term poor prognosis (OR: 1.064, 95%CI 1.012-1.119, p=0.015) in patients with acute ischemic stroke receiving intravenous thrombolysis after adjustment of age, gender, body mass index, smoking, alcohol consumer, onset-to-door time, door-to-needle time, and imaging score. CONCLUSION: The National Institute of Health Stroke Scale could be a promising indicator for the prognosis, and active intervention is needed to improve the quality of life in patients with acute ischemic stroke.

Sham acupuncture and placebo acupuncture in clinical trials / 中国针灸

The commonly used terms "sham acupuncture" and "placebo acupuncture" in clinical acupuncture research is compared and analyzed in this article. In terms of their respective characteristics, sham acupuncture has a wider scope, including various types of acupoints, needle insertion at non-acupoint or non-insertion at acupoints, while placebo acupuncture mainly focuses on non-insertion at acupoints. Sham acupuncture mainly emphasizes the appearance similarity to real acupuncture, while placebo acupuncture emphasizes both similarity in appearance and the absence of therapeutic effects. Properly distinguishing and applying sham acupuncture and placebo acupuncture can help standardize their usage in terminology. Considering the difficulty in setting up qualified placebo acupuncture, it is suggested that researchers use the term "sham acupuncture" to describe the acupuncture control methods used in clinical research.

Study on long-acting analgesic lappaconitine hydrobromide lyotropic liquid crystal injection / 药学学报

Long-acting analgesia is a common clinical treatment method after surgery. The slow-release injection with long-acting analgesia has the advantages of less medication frequency and stable effect. In this study, the analgesic drug lappaconitine hydrobromide lyotropic liquid crystal injection was prepared, and its sustained release mechanism, drug release and pharmacodynamic characteristics were evaluated. The results of polarizing microscope and freeze-transmission electron microscope showed that the lyotropic liquid crystal injection of the liquid crystal precursor preparation of lappaconitine hydrobromide could be obtained by the combination of glycerol monooleate (GMO) and soybean lecithin (SPC) in different proportions. The results of dissolution study in vitro showed that the drug release rate of different forms of liquid crystal preparations was layered liquid crystal > cubic liquid crystal > hexagonal liquid crystal. The mathematical model fitting results of the release data showed that the external release of layered liquid crystal, cubic liquid crystal and hexagonal liquid crystal conforms to the Ritger-Peppas model, and the release mechanism was Fick diffusion. The results of pharmacodynamics study in vivo showed that the analgesic effect of lappaconitine hydrobromide lyotropic liquid crystal injection lasted for 3 days, and there was no abnormality in the incision and local tissue, showing good safety and tolerance. The study on drug release and elimination process of the in vivo gel repository showed that lappaconitine hydrobromide could be completely released from the lyotropic liquid crystal 3 days after administration, and the sustained-release materials could be gradually eliminated locally. All animal experiments were approved by the Experimental Animal Ethics Committee of the Shanghai Institute of Materia Medica, Chinese Academy of Sciences (No. 2021-08-GY-61) and the experiments were conducted in accordance with the relevant guiding principles and regulations. The lyotropic liquid crystal injection of lappaconitine hydrobromide prepared in this study presented a solution state at room temperature, and underwent phase transition in contact with the body fluid at the administration site, formed a drug depot and exerted a slow drug release effect. This preparation can reduce systemic toxicity, prolong the duration of analgesia, reduce the number of administrations, improve the compliance of postoperative patients, and provide a reference for the design of long-term sustained release analgesic preparations.

Progress of neoadjuvant therapy for high-risk prostate cancer in the era of novel hormonal therapy / 现代泌尿外科杂志

In the past, the use of neoadjuvant androgen deprivation therapy (ADT) for prostate cancer did not exhibit survival benefits and was not recommended by the practicing guidelines. In recent years, with the emergence of novel hormonal therapeutics such as Abiraterone, Enzalutamide, Apalutamide and Darolutamide, the interest for neoadjuvant therapy has been reignited. Here, we summarize the four categories of neoadjuvant therapy with new hormonal agents, and discuss how to evaluate the efficacy and explore the molecular mechanism after neoadjuvant therapy.

Construction of a Spink5 conditional knockout mouse model and analysis of its phenotype / 中华皮肤科杂志

Objective:To construct a serine protease inhibitor Kazal type-5 (Spink5) conditional knockout mouse model, and to identify its phenotype.Methods:B cell-specific Spink5 conditional knockout mice of genotype Mb1 cre/+Spink5 floxp/floxp were constructed by using clustered regularly interspaced short palindromic repeats (CRISPR) /CRISPR-associated protein 9 (Cas9) technology, and served as the knockout group. Mice of genotype Mb1 +/+Spink5 floxp/floxp served as the control group. The mice of genotype Mb1 cre/+Spink5 floxp/floxp or Mb1 +/+Spink5 floxp/floxp were sacrificed when they were 4 to 6 weeks old, splenic mononuclear cells were isolated, and B lymphocytes and non-B lymphocytes were sorted by flow cytometry and fluorescence-activated cell sorting. Genotype identification was performed by PCR, and protein expression of lymphoepithelial Kazal-type-related inhibitor (LEKTI) was determined by Western blot analysis. Skin tissues were resected from the mice, and subjected to hematoxylin-eosin staining for measuring the epidermal thickness. Immunofluorescence staining was performed to determine fluorescence intensity of LEKTI protein in the mouse skin tissues. Paired t test or two-independent-sample t test was used for comparisons between groups. Results:Genotype identification results demonstrated that the stable B lymphocyte-specific Spink5 conditional knockout mouse model was successfully constructed. Western blot analysis revealed that the relative protein expression of LEKTI in the B lymphocytes in the knockout group was 0.01 ± 0.02, which was significantly lower than that in the non-B lymphocytes in the knockout group (0.66 ± 0.11, t = 9.99, P < 0.001) , and that in the B lymphocytes in the control group (1.08 ± 0.13, t = 13.78, P < 0.001) . Among 39 mice in the knockout group, 4 presented with dry skin and scattered scaly hypertrophic maculopapules. The epidermal thickness of the lesional skin tissues in the knockout group was 90.42 ± 21.31 μm, significantly higher than that of the non-lesional skin tissues in the knockout group (29.71 ± 3.63 μm, t = 5.05, P = 0.002) and that of normal skin tissues in the control group (12.42 ± 2.21 μm, t = 6.74, P < 0.001) . Immunofluorescence staining showed no significant difference in the fluorescence intensity of LEKTI protein among the lesional skin tissues (46.21 ± 1.21) , non-lesional skin tissues (46.62 ± 2.13) in the knockout group and normal skin tissues in the control group (47.69 ± 1.71, P > 0.05) . Conclusion:The B lymphocyte-specific Spink5 conditional knockout mouse model was successfully constructed, which provides a basis for further exploring mechanisms underlying skin barrier defects and immune dysfunction in Netherton syndrome.

Effect of Fufang Shelong Capsules on Rats with Membranous Nephropathy Based on p38 MAPK Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the nephroprotective and anti-inflammatory effects of Fufang Shelong capsules （FFSL） in rats with membranous nephropathy （MN）， and the role of the p38 mitogen-activated protein kinase （MAPK） signaling pathway. MethodMale SD rats of SPF grade were divided into a normal group and an experimental group. The MN model was induced by tail vein injection of cationized bovine serum albumin in the experimental group. After screening， the eligible model rats were included and divided into a positive control group （tripterygium glycosides tablets） and low-， medium-， and high-dose FFSL groups （0.375， 0.75， 1.5g·kg-1）. The rats were treated correspondingly for eight weeks， and urine protein was detected during drug intervention. Renal function and inflammation-related indicators were detected after drug intervention. The changes in 24-hour urine total protein （24 h UP）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， tumor necrosis factor-α （TNF-α）， creatinine （Cr）， blood urea nitrogen （BUN）， total protein （TP）， albumin （Alb）， and total cholesterol （TC） were detected. Flow cytometry was used to detect CD4+/CD8+ changes. Kidney tissues were collected to observe pathological changes under a light microscope and an electron microscope. The protein expression of p38 MAPK and phosphorylated p38 MAPK （p-p38 MAPK） in kidney tissues was detected by Western blot. ResultCompared with the normal group， the model group showed increased 24 h UP （P<0.01）， elevated serum Cr， BUN， TC， IL-6， IL-8， and TNF-α （P<0.05，P<0.01）， decreased serum Alb and TP levels （P<0.05，P<0.01）， increased CD4+/CD8+ in the peripheral blood （P<0.01）， and up-regulated protein expression of p38 MAPK and p-p38 MAPK in kidney tissues （P<0.05）. Additionally， in the model group， immune complex deposition and foot process fusion， accompanied by infiltration of inflammatory cells， were observed on the epithelial side of the basement membrane in the pathological kidney tissues. Compared with the model group， the groups with drug intervention showed declining 24 h UP levels at six weeks （P<0.05，P<0.01）， decreased serum Cr， BUN， TC， IL-6， IL-8， and TNF-α （P<0.05，P<0.01）， increased serum Alb and TP levels （P<0.05，P<0.01）， reduced CD4+/CD8+ in the peripheral blood （P<0.01）， improved renal pathological damage， and down-regulated p38 MAPK and p-p38 MAPK in kidney tissues （P<0.05，P<0.01）. ConclusionFFSL can decrease the expression of inflammatory factors， reduce proteinuria， delay kidney damage， and protect kidney function by inhibiting the expression of the p38 MAPK signaling pathway.

Objective: To investigate the sonographic features of primary thyroid lymphoma (PTL) and to evaluate the clinical significance of ultrasound-guided core needle biopsy (US-CNB) in PTL. Methods: A total of 24 patients with suspected PTL in Sir Run Run Shaw Hospital from January 2013 to June 2018 were analyzed retrospectively. All cases were confirmed by pathology, of them 23 patients received US-CNB and 1 patient chose operation without US-CNB, including 5 males and 19 females, aged from 39 to 75 years old. The effectiveness and safety of 23 patients with US-CNB were evaluated, and the sonographic features of 20 patients with PTL diagnosed by pathology were analyzed. Descriptive statistical methods were used in the study. Results: In the 23 patients with suspected PTL underwent US-CNB, 18 patients were diagnosed as PTL, 4 patients were respectively diagnosed as subacute thyroiditis, anaplastic carcinoma, Hashimoto's thyroiditis, and fibro thyroiditis, and the another patient was hard to diagnose by US-CNB and then was diagnosed as PTL by surgical biopsy. The success rate of US-CNB for diagnosis of PTL was 18/19, and no severe complications occurred in the patients with US-CNB. The other case was diagnosed as PTL by surgical biopsy without US-CNB. Sonographic features of 20 cases with PTL (18 cases diagnosed by US-CNB and 2 cases by surgery or surgery biopsy) were as follows: (1) Most nodules had irregular shapes and unsmooth margins; (2) Hypoechoic or markedly hypoechoic nodules with honeycombed or cord structures were observed in most cases; (3) Calcification was rare; (4) Multiple lesions were common; (5) Abundant intralesional vascularization was commonly observed; (6) Most cases had intensification of posterior acoustic enhancement; (7) Thyroid gland enlargement or with irregular shape; and (8) PTL often accompanied with lymph nodes enlargement in lateral neck or central region. Conclusion: PTL has certain sonographic features, with assistance of US-CNB, more accurate diagnosis of PTL can be obtained.

Application and reflection on pilot study in acupuncture clinical research / 中国针灸

Pilot study is essential prerequisite for large-scale research. Acupuncture is a complex intervention measure. The factors of its clinical effect and effect mechanism are complicated. Hence, the resource waste is easily induced in research if the large-scale clinical research is rashly carried out before scientific verification. Currently, there is still a lack of high-quality evidence of clinical research, which affects the promotion and application of the curative effect of acupuncture. The pilot study of acupuncture can evaluate the feasibility and the process coordination of trial, optimize program and process and provide the basis of sample size calculation prior to launching a full-scale trial. Thereby, the methodological quality of acupuncture research and the reliability of trial results can be improved. In the paper, the arguments focus on the definition, design and report of pilot study so as to provide the approaches and references for the design and implementation of pilot study of clinical research of acupuncture.

Clinical Recommendations for Perioperative Immunotherapy-induced Adverse Events in Patients with Non-small Cell Lung Cancer / 中国肺癌杂志

BACKGROUND@#Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE).@*METHODS@#This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE.@*RESULTS@#This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively.@*CONCLUSIONS@#Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Some patients had dental anomalies, ametropia and allergy, and a few were combined with immune impairment, but without overt signs of immunodeficiency. Only one patient had multisystem anomalies and profound immune deficiency.@*Conclusions@#BCL11B is essential for development of the nervous and the immune system. In this study, the de novo mutation of BCL11B gene resulted in neurodevelopmental and immunological disorders.

Urodynamic assessment of bladder storage function after radical hysterectomy for cervical cancer / 中华医学杂志(英文版)

BACKGROUND@#After radical hysterectomy for cervical cancer, the most common complication is lower urinary tract symptoms. Post-operatively, bladder capacity can alter bladder function for a prolonged period. This study aimed to identify factors affecting bladder storage function.@*METHODS@#A multicenter, retrospective cohort study was conducted. Information of patients with stages IA2 to IIB cervical cancer with urodynamic study results were retrospectively collected from nine hospitals between June 2013 and June 2018 according to the inclusion criteria. Demographic, surgical, and oncological data were collected. The univariate and multivariate logistic regression was used to identify clinical factors associated with bladder storage function.@*RESULTS@#Two hundred and three patients with cervical cancer had urodynamic testing post-operatively. Ninety-five (46.8%) patients were diagnosed with stress urinary incontinence (SUI). The incidence of low bladder compliance (LBC) was 23.2%. Twenty-seven (13.3%) patients showed detrusor overactivity (DO). Fifty-seven patients (28.1%) presented with a decreased maximum cystometric capacity (DMCC). The probability of composite bladder storage dysfunction was 68.0%. Multivariate analysis confirmed that laparoscopy represents a protective factor for SUI with an odds ratio of 0.498 (P = 0.034). Patients who underwent a nerve-sparing procedure were less odds to experience SUI (P = 0.014). A significant positive correlation between LBC and DO was observed (P < 0.001). A greater length of the resected vagina and chemoradiotherapy were common risk factors for LBC and DO, while radiotherapy exerted a stronger effect than chemotherapy. Additionally, patients who received chemoradiotherapy frequently developed a DMCC. The follow-up time was not correlated with bladder storage function.@*CONCLUSION@#A nerve-sparing procedure without longer resected vagina is recommended for protecting the bladder storage function.
