ABSTRACT

Neoadjuvant chemotherapy (NAC) has shown promising results in patients with locally advanced penile cancer. However, no consensus exists on its applications for locally advanced penile cancer. Thus, it is unclear which kind of chemotherapy regimen is the best choice. Consequently, a systematic search of PubMed, Web of Science, and EMBASE was performed in March 2021 to assess the efficacy and safety of NAC for the treatment of patients with locally advanced penile cancer. The Newcastle-Ottawa Scale was used to assess the risk of bias in each study. This study synthesized 14 published studies. The study revealed that patients who achieved an objective response to NAC obtained a better survival outcome compared with those who did not achieve an objective response. In addition, the objective response rates (ORRs) and pathological complete response (pCR) rates were 0.57 and 0.11, respectively. The incidence of grade ≥3 toxicity was 0.36. Subgroup analysis found that the ORR and pCR of the taxane-platinum (TP) regimen group performed better than those of the nontaxane-platinum (NTP) regimen group (0.57 vs 0.54 and 0.14 vs 0.07, respectively). Moreover, the TP regimen group had more frequent toxicity than the NTP regimen group (0.41 vs 0.26). However, further studies were warranted to confirm the findings.

ABSTRACT

To reduce treatment-related side effects in low-risk prostate cancer (PCa), both focal therapy and deferred treatments, including active surveillance (AS) and watchful waiting (WW), are worth considering over radical prostatectomy (RP). Therefore, this study aimed to compare long-term survival outcomes between focal therapy and AS/WW. Data were obtained and analyzed from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with low-risk PCa who received focal therapy or AS/WW from 2010 to 2016 were included. Focal therapy included cryotherapy and laser ablation. Multivariate Cox proportional hazards models were used to compare overall mortality (OM) and cancer-specific mortality (CSM) between AS/WW and focal therapy, and propensity score matching (PSM) was performed to reduce the influence of bias and unmeasured confounders. A total of 19 292 patients with low-risk PCa were included in this study. In multivariate Cox proportional hazards model analysis, the risk of OM was higher in patients receiving focal therapy than those receiving AS/WW (hazard ratio [HR] = 1.35, 95% confidence interval [CI]: 1.02-1.79, P = 0.037), whereas no significant difference was found in CSM (HR = 0.98, 95% CI: 0.23-4.11, P = 0.977). After PSM, the OM and CSM of focal therapy and AS/WW showed no significant differences (HR = 1.26, 95% CI: 0.92-1.74, P = 0.149; and HR = 1.26, 95% CI: 0.24-6.51, P = 0.782, respectively). For patients with low-risk PCa, focal therapy was no match for AS/WW in decreasing OM, suggesting that AS/WW could bring more overall survival benefits.

ABSTRACT

The research on the processing mechanism of Chinese medicine is the key and core foundation to improve processing technologies of Chinese medicine, formulate the quality standards of Chinese medicinal pieces, enhance the clinical efficacy of Chinese medicine, enrich Chinese medicine processing theories, and promote the development of Chinese medicine processing. Many researc-hers have conducted in-depth exploration on the processing mechanism of Chinese medicine in the 20 years in the 21 st century. Significant progress has been made in the transformation of chemical components during the processing, the change of active components in the body, the law of toxicity attenuation in the processing of toxic Chinese medicine, the mechanism of efficacy enhancement and toxicity attenuation of processing with auxiliary materials, and the application of new biomedical technologies. At present, the processing mechanism of multiple Chinese medicines has been preliminarily clarified, which has greatly promoted the development of Chinese me-dicine processing. The development of the processing mechanism of Chinese medicine reveals that the in vitro transformation of chemical components is combined with the in vivo absorption, transport, and metabolism, and the macroscopic biological effects of the organism are combined with the cells, molecules, targets, and pathways in the study of the processing mechanism of Chinese medicine. More attention has been paid to exploring the processing mechanism from the overall level, and a modern systematic research system on the processing mechanism of Chinese medicine has been initially formed. To further promote the scientific development of Chinese me-dicine processing, the present study proposed that the research on the processing mechanism of Chinese medicine should take Chinese medicine properties into account, focus on the influence of disease condition on the mode of action and effect strength of the drugs, comply with the characteristics of clinical compound compatibility of Chinese medicine, use the holistic view research strategies of systems bio-logy, and deeply explore the processing mechanism of Chinese medicine from traditional Chinese medicine theories and the characteristics of clinical medication of Chinese medicine.

ABSTRACT

Objective:To investigate the changes in peripheral blood and liver-infiltrating natural killer-like B (NKB) cells in patients with primary hepatocellular carcinoma (HCC), and to assess the influence of IL-18 on NKB cells in vitro and the underlying mechanism. Methods:Forty-three HCC patients and 21 normal controls (NC) were enrolled in the study. Peripheral blood samples were collected to isolate plasma and peripheral blood mononuclear cells (PBMC). Intrahepatic lymphocytes (IHL) were isolated from tumor tissues and para-tumor tissues obtained from 16 HCC patients who received surgery. IL-12, IL-18 and IL-18 binding protein (IL-18BP) levels in plasma were measured by enzyme linked immunosorbent assay. The percentages of CD3 -NKp46 + CD19 + NKB cells and IL-18 + NKB cells in PBMC and IHL were analyzed by flow cytometry. Changes in the percentages of NKB cells and IL-18 + NKB cells were measured after stimulating PBMC and IHL with recombinant human IL-18 (1 ng/ml and 10 ng/ml). Changes in IL-18BP levels in the culture supernatants and phosphorylated nuclear factor-κB (NF-κB) in NKB cells were also assessed. Student′s t test, one-way analysis of variance or LSD-t test was used for statistical analysis. Results:There was no significant difference in plasma IL-12 level between HCC patients and NC ( P=0.245). Compared with NC, HCC patients had decreased IL-18 level in plasma [(224.3±58.89) pg/ml vs (327.0±52.27) pg/ml, P<0.000 1], but increased IL-18BP level [(4.421±0.97) ng/ml vs (0.92±0.18) ng/ml, P<0.000 1]. The percentages of peripheral blood NKB cells and IL-18 + NKB cells were lower in HCC patients than in NC [(2.68±1.23)% vs (8.88±2.95)% and (54.42±12.60)% vs (69.74±12.65)%, both P<0.000 1]. The percentage of NKB cells in IHL was reduced in tumor tissues as compared with that in para-tumor tissues [(2.89±0.86)% vs (4.66±1.17)%, P<0.000 1]. Moreover, the percentage of IL-18 + NKB cell was also down-regulated in tumor tissues as compared with that in para-tumor tissues [(51.50±13.18)% vs (62.13±9.24)%, P=0.013]. Recombinant human IL-18 stimulation reduced the IL-18BP level in the culture supernatants ( P<0.05). IL-18 stimulation at 1 ng/ml did not affect NKB cell percentage, IL-18 + NKB cell percentage or NF-κB phosphorylation in NKB cells from PBMC or IHL ( P>0.05), while 10 ng/ml of IL-18 not only elevated NKB cell percentage and IL-18+ NKB cell percentage, but also promoted NF-κB phosphorylation in NKB cells ( P<0.01). Conclusions:In vitro stimulation with high concentration of IL-18 might promote NF-κB phosphorylation by inhibition of IL-18BP expression. This process might play a positive feedback role to induce the activation of NKB cells and IL-18 secretion.

ABSTRACT

Objective:To investigate the impacts of electron streaming effect (ESE) on out-of-field dose distribution in 1.5 T MRI-guided radiotherapy.Methods:Firstly, the Monaco v5.40.1 (Elekta AB, Stockholm, Sweden) treatment planning system (TPS) was implemented to investigate the ESE in a square field (5 cm × 5 cm) at the entry and exit sides of a special homogeneous water phantom. Afterward, a retrospective investigation was conducted into one laryngeal cancer case and one breast cancer case who had been treated on a conventional linear particle accelerator (linac). Then doses were recalculated in the Monaco system using a Unity machine model. Meanwhile, the out-of-field skin dose enhancement induced by ESE was investigated.Results:ESE-induced dose variations were observed at both the entry and exit sides of the phantom surface in the presence of a magnetic field, with the ESE on the exit side notably stronger than that on the entry side. For the laryngeal cancer case, the ESE was not notable and had insignificant impacts on the out-of-field skin dose. In contrast, ESE-induced in-air high-dose region outside the body stretched to the chin area for the breast cancer case. This led to the skin dose escalation of the chin at D1 cm 3 454.6 cGy. After the application of 1 cm bolus, the corresponding skin dose of the chin D1 cm 3 reduced to as low as 113.6 cGy, which is almost equivalent to that in the absence of a magnetic field ( D1 cm 3=92.5 cGy). Conclusions:The ESE in a magnetic field can alter out-of-field dose and lead to local dose enhancement along the electron path. Although the ESE had insignificant impacts on the out-of-field dose of the laryngeal cancer case, it reached the chin area of the breast cancer case. ESE can be effectively shielded by adding protective bolus.

ABSTRACT

Objective:To investigate the value of BRAF V600E mutation combined with 2015 American Thyroid Association (ATA) Guidelines ultrasound (US) pattern in fine-needle aspiration (FNA) cytology of thyroid nodules with atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS).Methods:This study retrospectively enrolled 96 consecutive patients with 101 AUS/FLUS thyroid nodules who underwent preoperative US, FNA, and BRAF V600E mutation analysis. All AUS/FLUS nodules were classified based on US pattern-based risk stratification of 2015 ATA Guidelines. With postoperative pathology as the gold standard, the diagnostic value of BRAF V600E mutation, US pattern and the combination of two methods were compared.Results:Postoperative pathology confirmed 33 benign nodules and 68 malignant nodules. The mutation rates of BRAF V600E in AUS/FLUS nodules was 51.5%. The sensitivity, specificity, and accuracy of BRAF V600E in the diagnosis AUS/FLUS nodules were 72.1%, 90.9% and 78.2%, respectively. The ROC curve demonstrated that the best cut-off of US pattern was high suspicion. The sensitivity, specificity, and accuracy of US pattern in the diagnosis of AUS/FLUS nodules were 63.2%, 81.8% and 69.3%, respectively. The accuracy of US pattern in determining AUS/FLUS nodules without BRAF V600E mutation was 70.6%. The sensitivity, specificity, and accuracy of the combination of two methods in the differential diagnosis of AUS/FLUS nodules were 89.7%, 75.8%, and 85.1%, respectively. The combination had the highest sensitivity ( P<0.05). Conclusions:BRAF V600E mutation has a good diagnostic value for differentiating benign and malignant AUS/FLUS nodules. Combined with US pattern, the differential diagnostic value for AUS/FLUS nodules without BRAF V600E mutation can be improved, and the sensitivity can be raised.

ABSTRACT

Apoptosis is proved responsible for renal damage during ischemia/reperfusion. The regulation for renal apoptosis induced by ischemia/reperfusion injury (IRI) has still been unclearly characterized to date. In the present study, we investigated the regulation of histone acetylation on IRI-induced renal apoptosis and the molecular mechanisms in rats with the application of curcumin possessing a variety of biological activities involving inhibition of apoptosis. Sprague–Dawley rats were randomized into four experimental groups (SHAM, IRI, curcumin, SP600125). Results showed that curcumin significantly decreased renal apoptosis and caspase-3/-9 expression and enhanced renal function in IRI rats. Treatment with curcumin in IRI rats also led to the decrease in expression of p300/cyclic AMP response element-binding protein (CBP) and activity of histone acetyltransferases (HATs). Reduced histone H3 lysine 9 (H3K9) acetylation was found near the promoter region of caspase-3/-9 after curcumin treatment. In a similar way, SP600125, an inhibitor of c-Jun N-terminal kinase (JNK), also attenuated renal apoptosis and enhanced renal function in IRI rats. In addition, SP600125 suppressed the binding level of p300/CBP and H3K9 acetylation near the promoter region of caspase-3/-9, and curcumin could inhibit JNK phosphorylation like SP600125. These results indicate that curcumin could attenuate renal IRI via JNK/p300/CBP-mediated anti-apoptosis signaling.

ABSTRACT

COVID-19 pandemic caused by SARS-CoV-2 infection severely threatens global health and economic development. No effective antiviral drug is currently available to treat COVID-19 and any other human coronavirus infections. We report herein that a macrolide antibiotic, carrimycin, potently inhibited the cytopathic effects (CPE) and reduced the levels of viral protein and RNA in multiple cell types infected by human coronavirus 229E, OC43, and SARS-CoV-2. Time-of-addition and pseudotype virus infection studies indicated that carrimycin inhibited one or multiple post-entry replication events of human coronavirus infection. In support of this notion, metabolic labelling studies showed that carrimycin significantly inhibited the synthesis of viral RNA. Our studies thus strongly suggest that carrimycin is an antiviral agent against a broad-spectrum of human coronaviruses and its therapeutic efficacy to COVID-19 is currently under clinical investigation.

ABSTRACT

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but severe diseases. This study aimed to validate the predictive ability of risk models in patients with SJS/TEN and propose possible refinement in China. Patients in the Department of Dermatology of Huashan Hospital from January 2008 to January 2019 were included. Results showed that the severity-of-illness score for TEN (SCORTEN) had a good discrimination (area under the receiver operating characteristic curve (AUC), 0.78), and it was superior to auxiliary score (AS) and ABCD-10, which indicates age, bicarbonate level, cancer, dialysis, and 10% involved body surface area (AUC, 0.69 and 0.68, respectively). The calibration of SCORTEN (Hosmer-Lemeshow goodness-of-fit test, P = 0.69) was also better than that of AS (P = 0.25) and ABCD-10 (P = 0.55). SCORTEN and ABCD-10 were similar (Brier score (BS), 0.04 and 0.04) in terms of accuracy of predictions. In addition, the imaging appearance of pulmonary consolidation on computed tomography was associated with high mortality. Refined models were formed using the variables and this imaging appearance. The refined AS and ABCD-10 models were similar in discrimination compared with the original SCORTEN (0.74 vs. 0.78, P = 0.23; 0.74 vs. 0.78, P = 0.30, respectively). Therefore, SCORTEN showed good discrimination performance, calibration, and accuracy, and refined AS or ABCD-10 model may be an option when SCORTEN variables are not available.

ABSTRACT

Delayed-or non-healing wounds caused by trauma, surgical procedures, acute diseases, or chronic diseases, and proli-ferating scar have a serious impact on patients' quality of life and increase the economic and psychological burden on their families. Therefore, how to accelerate wound healing and obtain satisfactory aesthetic results is of great concern to researchers and is an urgent clinical problem to be solved. In recent years, the mechanisms of Chinese medicinal materials in accelerating wound healing and inhi-biting scar formation by regulating cytokines have been clarified, which provides a scientific basis for revealing the efficacy of Chinese medicinal materials against clinical trauma. This review focuses on the therapeutic effects of active ingredients, extracts, and topical preparations of Chinese medicinal materials through regulating cytokines in the inflammation, proliferation, and remodeling phases of wound healing. It is expected to provide evidence for the application of Chinese medicinal materials in wound therapy.

ABSTRACT

@#AIM: To explore the clinical effects of Glucocorticoids, Cyclophosphamide and Octreotide in the treatment of Graves' ophthalmopathy(GO). <p>METHODS: A retrospective study was conducted. Totally 102 patients(152 eyes)with GO admitted to the hospital between June 2018 and October 2019 were divided into glucocorticoid group(33 cases, 51 eyes), cyclophosphamide group(38 cases, 59 eyes), and octreotide group(31 cases, 42 eyes)according to the treatment method. All groups received 12wk of treatment. The treatment results were comparatively analyzed. Changes in proptosis degree, diplopia, intraocular pressure and visual acuity before and after treatment were measured. Clinical activity scoring(CAS)of thyroid associated eye movements was performed. Changes in ocular axes, eyeball transverse diameter, ocular apex distance, retrobulbar perimeter, area and volume were measured by eye ultrasound. Changes in thyrotropin receptor antibody(TRAb), thyroid peroxidase antibody(TPOAb)and thyroid volume before and after treatment were determined. The incidence of adverse reactions was counted. <p>RESULTS: Compared with octreotide group, grades of curative effect of glucocorticoid group and cyclophosphamide group were better(<i>P</i><0.05), but there was no statistically significant difference between glucocorticoid group and cyclophosphamide group(<i>P</i>>0.05). After 12wk of treatment, the proptosis degree and CAS scores of the three groups were decreased(<i>P</i><0.05), visual acuity and conscious diplopia were improved, ocular apex distance, retrobulbar perimeter, area and volume, TRAb, TPOAb and thyroid volume were decreased(<i>P</i><0.05). The proptosis degree, CAS scores, ocular apex distance, retrobulbar perimeter, area and volume, TRAb, TPOAb and thyroid volume of glucocorticoid group and cyclophosphamide group were smaller than those of octreotide group(<i>P</i><0.05), without statistically significant differences between glucocorticoid group and cyclophosphamide group(<i>P</i>>0.05). During treatment, the incidences of weight gain and the total incidence of adverse reactions were higher in glucocorticoid group than in cyclophosphamide group and octreotide group(<i>P</i><0.0167), but there were no statistically significant differences between cyclophosphamide group and octreotide group(<i>P</i>>0.0167). <p>CONCLUSION:Glucocorticoids and cyclophosphamide are better than octreotide in the treatment of GO, which can better improve ocular signs and thyroid-related lesions. Additionally, the incidence of adverse reactions caused by cyclophosphamide is lower than glucocorticoids, and its safety is higher. Therefore, cyclophosphamide is the first choice for treating GO.

ABSTRACT

Inhibition of immune checkpoints is at the forefront of immunotherapy for lung cancer. However, a high percentage of lung cancer patients do not respond to these immunotherpy or their responses are transient, indicating the existence of immune resistance. Emerging evidence suggested that the interactions between cancer cells and immune system were continuous and dynamic. Here, we review how a range of cancer-cell-autonomous characteristics, tumor-microenvironment factors, and host-related influences account for heterogenous responses. Furthermore, with the identification of new targets of immunotherapy and development of immune-based combination therapy, we elucidate the methods might useful to overcome resistance.

ABSTRACT

OBJECTIVE@#To investigate the expression of WTAP gene in acute myeloid leukemia (AML) and its clinical significance.@*METHODS@#74 acute myeloid leukemia patients with non-M3 type and 19 normal donors were selected, and real-time quantitative polymerase chain reaction was used to detect the mRNA expression level of WTAP gene in their bone marrow cells. The relationship between the mRNA expression level of WTAP gene and the clinical characteristics was analyzed.@*RESULTS@#The relative mRNA expression of WTAP gene in the non-M3 AML group was significantly higher than that in the healthy control group, and the difference showed statistically significant (P0.05) according to the classification of FAB. The mRNA expression level of WTAP gene in FLT3-ITD mutated AML patients was higher than that in FLT3-ITD unmutated group (P=0.016), and the mRNA expression level of WTAP gene in AML patients with CEBPα mutation was lower than that in CEBPα unmutated group (P=0.016). The expression level of WTAP mRNA was positively correlated with WT1 expression (r=0.6866, P0.05). The expression level of WTAP mRNA showed no obvious effect on the complete remission of patients after first treatment. The different expression level of WTAP gene at initial diagnosis showed also no effect on the overall survival time of patients.@*CONCLUSION@#The expression level of WTAP gene is increasing in new diagnosed non-M3 acute myeloid leukemia. There is a positive correlation between the expression level of WTAP gene and the expression level of WT1 fusion gene. WTAP mRNA always shows higher expression in patients with FLT3-ITD mutation than that in patients without FLT3-ITD mutation, and shows lower expression in patients with CEBPα mutation than that in unmutated group.

ABSTRACT

This study aimed to analyze the methodological quality of systematic reviews of Shuxuening Injection and evaluate the efficacy and adverse reactions of Shuxuening Injection in the treatment of different diseases,in order to provide supportive evidence for clinical practice. Three Chinese databases and three English databases were retrieved to identify systematic reviews and Meta-analysis on the efficacy and safety of Shuxuening Injection in the treatment of diseases. The AMSTAR 2( a measurement tool to assess systematic reviews 2) tool was used to evaluate the methodological quality of the included systematic reviews,and tables were created to present the results of Meta-analyses. Twenty-four systematic reviews were included,all with very low methodological quality. Among the 16 AMSTAR-2 items,only 5 items had a compliance rate greater than 60. 0%,and 8 items had a compliance rate less than 50. 0%. For patients with cerebral infarction,Shuxuening Injection combined with conventional treatment was more effective than conventional treatment alone in terms of clinical efficiency and neurological deficit improvement. For patients with angina pectoris,Shuxuening Injection was superior to Danshen/Compound Danshen Injection in terms of the total effective rate of angina pectoris and total effective rate of ECG. The efficacy of Shuxuening Injection combined with conventional treatment is significantly better than conventional treatment.Shuxuening Injection( alone or combined with conventional treatments) was better than conventional treatments for cerebral hemorrhage,ischemic cerebrovascular disease,chronic pulmonary heart disease,vertigo and sudden deafness. Shuxuening Injection had better efficacy and lower incidence of adverse reactions,but the methodological quality of included systematic reviews was low. The results of this study still need to be verified by high-quality systematic reviews.
