The efficacy of radiotherapy based combined therapy for unresectable locally invasive bladder cancer and its associated factors analysis / 中华肿瘤杂志

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

Effect and mechanism investigation on improving kidney deficient in mice of Polygoni Multiflori Radix Praeparata based on plasma metabolomics / 药学学报

Plasma nontargeted metabolomics technology was developed for investigating the effect and mechanism of improving kidney deficient in mice of Polygoni Multiflori Radix Praeparata. Thirty-five ICR mice were randomly divided into the control group, the model group, the BB24 h (braising with black bean sauce for 24 hours) group, the BB32 h group, and the BB40 h group. Biochemical indices in blood plasma of mice were measured by collecting eye blood after modeling. Changes in plasma endogenous metabolites of mice from each group were determined by ultra-performance liquid chromatography-linear trap quadrupole-orbitrap XL (UPLC-LTQ-orbitrap XL), and differential metabolites were screened. The results of pharmacodynamic investigation showed that compared to the model group, the levels of estradiol increased obviously in the BB24 h (P < 0.05), and the levels of cortisol increased obviously in BB32 h (P < 0.05). The hormone level of mice with kidney deficiency was significantly improved after taking processed Polygonum multiflorum. A total of 70 differential endogenous metabolites in blood plasma of mice were identified from all treatment groups, which mainly involved glycerophospholipid meta-bolism, arachidonic acid metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and linoleic acid metabolism. The study indicated that Polygoni Multiflori Radix Praeparata may play the role of tonifying liver and kidney by improving the disorder of hypothalamic-pituitary-adrenal axis and regulating lipid metabolism in mice. Correlation analysis on differential metabolites in blood plasma and the chemical constituents showed that stilbene glycosides and saccharides may be the key pharmacodynamic material basis. The present study provides a new reference and theoretical foundation for revealing the potential pharmacodynamic material basis and mechanism investigation on tonifying liver and kidney of Polygoni Multiflori Radix Praeparata. This study was carried out following the ethical guidelines and regulations for the use of laboratory animals of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences and passed the animal experimental ethical review [No. SYXK (Jing) 2019-0003].

Activated PKB/GSK-3β synergizes with PKC-δ signaling in attenuating myocardial ischemia/reperfusion injury via potentiation of NRF2 activity: Therapeutic efficacy of dihydrotanshinone-I

@#Disrupted redox status primarily contributes to myocardial ischemia/reperfusion injury (MIRI). NRF2, the endogenous antioxidant regulator, might provide therapeutic benefits. Dihydrotanshinone-I (DT) is an active component in Salvia miltiorrhiza with NRF2 induction potency. This study seeks to validate functional links between NRF2 and cardioprotection of DT and to investigate the molecular mechanism particularly emphasizing on NRF2 cytoplasmic/nuclear translocation. DT potently induced NRF2 nuclear accumulation, ameliorating post-reperfusion injuries via redox alterations. Abrogated cardioprotection in NRF2-deficient mice and cardiomyocytes strongly supports NRF2-dependent cardioprotection of DT. Mechanistically, DT phosphorylated NRF2 at Ser40, rendering its nuclear-import by dissociating from KEAP1 and inhibiting degradation. Importantly, we identified PKC-δ-(Thr505) phosphorylation as primary upstream event triggering NRF2-(Ser40) phosphorylation. Knockdown of PKC-δ dramatically retained NRF2 in cytoplasm, convincing its pivotal role in mediating NRF2 nuclear-import. NRF2 activity was further enhanced by activated PKB/GSK-3β signaling via nuclear-export signal blockage independent of PKC-δ activation. By demonstrating independent modulation of PKC-δ and PKB/GSK-3β/Fyn signaling, we highlight the ability of DT to exploit both nuclear import and export regulation of NRF2 in treating reperfusion injury harboring redox homeostasis alterations. Coactivation of PKC and PKB phenocopied cardioprotection of DT in vitro and in vivo, further supporting the potential applicability of this rationale. Graphical abstract

Similar change laws of content of nine components in four processing methods of Polygoni Multiflori Radix Praeparata / 中国中药杂志

To standardize the processing technology of Polygoni Multiflori Radix Praeparata and stabilize its quality, the similar change laws of Polygoni Multiflori Radix Praeparata with different processing methods and time were analyzed. The processing time of Polygoni Multiflori Radix Praeparata was studied at 24, 32, 40, 48 h, and 4 different processing methods were studied, namely stewed with black bean sauce, steamed, steamed with black bean sauce, and steamed with black bean sauce and rice wine. The content of stilbene glycosides and anthraquinones were determined by HPLC-DAD method. UV method was used to determine the content of polysaccharides, and HPLC-ELSD method was used to determine the monosaccharides and oligosaccharides. The comparative chart of content determination, cluster analysis and entropy weight TOPSIS model was used to find the similar change laws and time interval of different processing methods of Polygoni Multiflori Radix Praeparata. The results demonstrated that around 32 h, the content of nine components in Polygoni Multiflori Radix Praeparata with different processing methods had similar change laws, and the decoction pieces had a high quality, indicating that the four processing methods of Polygoni Multiflori Radix Praeparata are likely to be used as one type of decoction piece with the same name.

The digestive tract is a target organ attacked by COVID-19. It is also the earliest affected organ other than the lung and must bear side effects from the anti-virus chemotherapy such as LPV/r. In this article, we aim to provide practical recommendations for a nutritional and metabolic management strategy for severe corona virus disease-19 (COVID-19) patients. These recommendations are based on the newest pathophysiological findings on the risk factors of malnutrition for COVID-19. We also systematically retrieve literatures on nutritional therapy for acute lung injuries from international and Chinese databases according to evidence-based principles. Our suggestions are: 1) Physicians should be mindful of gut injury when they focus on respiratory support, by monitoring and managing the nutritional status; 2) Periodical and dynamic nutritional risk evaluation is needed; 3) For severe patients, the feeding target of calorie and protein should be down-regulated; 4)The using of ω-3 fatty acids products should be in accordance with pharmacological indications; the forms and dosage should be determined individually.

Experimental Research Progress on Prevention and Treatment of Cognitive Dysfunction in Diabetes Mellitusby Traditional Chinese Medicine / 中国实验方剂学杂志

Cognitive dysfunction of diabetes mellitus is one of the complications of diabetes mellitus. Its clinical manifestations include decreased memory ability, learning ability, language expression and comprehension ability, and inattention. The pathogenesis is complex, which is related to various factors such as abnormal glucose metabolism, abnormal lipid metabolism, insulin resistance, abnormal phosphorylation of Tau protein, inflammatory reaction, oxidative stress, cholinergic system injury, neuronal cell apoptosis, et al. Although traditional hypoglycemic drugs such as metformin and glibenclamide have a little effect in controlling diabetic cognitive impairment, but there has no effective drugs for this disease which causes a heavy burden on families and society. The concepts of holism and preventing disease of traditional Chinese medicine(TCM)have obvious advantages in delaying the occurrence and development the complications.TCM believes that the basic pathogenesis of diabetic cognitive dysfunction is based on deficiency complicated with excess. The therapeutic principles includes tonifying the kidney essence, reinforcing Qi and nourishing Yin, dissipating phlegm for resuscitation, and promoting blood circulation to remove blood stasis.In recent years, there have been a lot of research achievements on the prevention and treatment of cognitive dysfunction in diabetes mellitus with TCM. Researchers of TCM do abundant researches, and find that TCM can improve cognitive dysfunction by lowering blood glucose,promoting intracellular cholesterol excretion, improving insulin resistance, lowering p-Tau, anti-oxidative stress, inhibiting inflammatory reactions, improving the function of cholinergic nerve, inhibiting neuronal apoptosis. The article reviews the experimental research on the prevention and treatment of cognitive dysfunction of diabetes mellitus by TCM and its extracts and reveals the target and mechanism, in order to provide sufficient scientific basis for TCM to prevent cognitive dysfunction of diabetes mellitus.

Total saponins of Aralia elata(Miq)Seem protect tumor necrosis factor-α-induced human umbilical vein endothelial cells via PI3K/Akt and NF-κB signal pathways / 中国药理学与毒理学杂志

It is now thought that atherosclerosis,although due to enhanced lipid deposition,is mainly the result of a series inflammatory process.Total saponins of Aralia elata (Miq)Seem(TASAES)from the Chinese traditional herb Longya Araliachinensis L.,a folk medicine used for treating various diseases, increasing energy and improving the body′s ability to prevent hypoxia in Asian countries has attracted widespread attention. However, the ability of TASAES on inflammation-triggered vascular endothelial cell injury, a key early event in the pathogenesis of atherosclerosis, and its potential mechanisms of this protection have never been demonstrated. The present study determined the anti-inflammatory and anti-apoptoticactivities and protective mechanisms of the total aralosides of Araliaelata(Miq)Seem (TASAES) ameliorate tumor necrosis factor-α (TNF-α)-induced human umbilical vein endothelial cells (HUVECs) injury. Our results indicate that TASAES pretreatment provided cytoprotective effects by suppressing TNF-α-induced HUVECs apoptosis, mitochondrial membrane depolarization, caspase-3 activation, and modulation of inflammatory factors (IL-6, MCP-1 and VCAM-1), meanwhile inhibiting NF- κB transcription. Furthermore, the effect was correlated with the activation of the PI3K/Akt signal pathway. Blocking Akt activation with the PI3K inhibitor LY294002 effectively reversed the protective effect of TASAES against TNF-α-induced cell apoptosis.Moreover,the PI3K inhibitor partially blocked the effects of TASAES on the increasing of Bcl-2 and Bcl-xl protein expression,and inactivation of Bax protein expression. In conclusion, the results showed that TASAES decreased the inflammation and apoptosis of HUVECs caused by TNF-α treatment,and PI3K played a crucial role in enhancing cell sur-vival during this process.

Clinical practice guidelines for the treatment of primary liver cancer with integrative traditional Chinese and Western medicine / 中西医结合学报

Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

Effects of Inner Heating Dry Needle Therapy on Nonspecific Chronic Neck Pain: A Ultrasound Elastography Study / 中国康复理论与实践

@#Objective To explore the clinical effect of inner heating dry needle therapy on nonspecific chronic neck pain (NCNP). Methods From October, 2017 to March, 2018, 60 patients with NCNP were randomly divided into needle group (n=30) and magner group (n=30). The needle group received inner heating dry needle therapy, and the magner group received hot magner therapy. They were measured the strain ratio (SR) of bilateral trapezius muscles, scalp clamp muscles, cephalospinal muscles, semispinalis muscles and multifidus muscles with ultrasound elastography before, and one week and one month after treatment, respectively, while they were assessed with Visual Analogue Scale (VAS) of pain and Neck Disability Index (NDI). Results The scores of VAS and NDI decreased in both groups one week and one month after treatment (t>2.693, P<0.05), and decreased more in the needle group than in the magner group (F>8.048, P<0.001). SR of all the muscles decreased in the needle group one week and one month after treatment (F>6.22, P<0.01), and only decreased in the right cephalospinal muscles in the magner group (F=4.35, P<0.05).Conclusion Inner heating dry needle therapy could recover the neck muscle elasticity to relieve pain and improve ceivical function in patients with NCNP.

Anti-inflammatory effect of external use of escin on cutaneous inflammation: possible involvement of glucocorticoids receptor / 中国天然药物

Escin, as an internally applied anti-inflammatory agent, has been widely used in the treatment of inflammation and edema resulting from trauma or operation in the clinic. However, the effect of its external use on cutaneous inflammation and edema remains unexplored. In the present study, the anti-inflammatory and anti-edematous effects of external use of escin were studied in carrageenan-induced paw edema and histamine-induced capillary permeability in rats, paraxylene-induced ear swelling in mice, and cotton pellet-induced granuloma in rats. Effects of external use of escin gel on prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) were determined by ELISA. The anti-inflammatory mechanism was explored by detecting the expression of glucocorticoid receptor (GR) with Western blotting and Real-time PCR analyses, with further exploration of nuclear factor-κB (NF-κB), p38 mitogen-activated protein kinase (P38MAPK) and activator protein-1 (AP-1) expressions. We demonstrated that external use of escin showed significant anti-inflammatory effects on acute and chronic inflammation in different animal models and its anti-inflammatory effects might be related to down-regulation of PGE2, TNF-α, and IL-1β. The results also showed that escin exerted its anti-inflammatory effects by promoting the expression of GR, with the possible mechanism being inhibition of the expressions of GR-related signaling molecules such as NF-κB and AP-1.
