Effect and Safety of Herbal Medicine Foot Baths in Patients with Diabetic Peripheral Neuropathy: A Multicenter Double-Blind Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect and safety of foot baths with Tangbi Waixi Decoction (TW) in treating patients with diabetic peripheral neuropathy (DPN). METHODS: It is a multicenter double-blinded randomized controlled trial. Participants with DPN were recruited between November 18, 2016 and May 30, 2018 from 8 hospitals in China. All patients received basic treatments for glycemic management. Patients received foot baths with TW herbal granules either 66.9 g (intervention group) or 6.69 g (control group) for 30 min once a day for 2 weeks and followed by a 2-week rest, as a therapeutic course. If the Toronto Clinical Scoring System total score (TCSS-TS) ⩾6 points, the patients received a total of 3 therapeutic courses (for 12 weeks) and were followed up for 12 weeks. The primary outcome was change in TCSS-TS score at 12 and 24 weeks. Secondary outcomes included changes in bilateral motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of the median and common peroneal nerve. Safety was also assessed. RESULTS: Totally 632 patients were enrolled, and 317 and 315 were randomized to the intervention and control groups, respectively. After the 12-week intervention, patients in both groups showed significant declines in TCSSTS scores, and significant increases in MNCV and SNCV of the median and common peroneal nerves compared with pre-treatment (P<0.05). The reduction of TCSS-TS score at 12 weeks and the increase of SNCV of median nerve at 24 weeks in the control group were greater than those in the intervention group (P<0.05). The number of adverse events did not differ significantly between groups (P>0.05), and no serious adverse event was related with treatment. CONCLUSION: Treatment of TW foot baths was safe and significantly benefitted patients with DPN. A low dose of TW appeared to be more effective than a high dose. (Registry No. ChiCTR-IOR-16009331).

Hyperthermia is a promising potential adjunct to treating sporotrichosis: A refractory case of HIV sporotrichosis and in vitro experiments on Sporothrix spp.

BACKGROUND: Hyperthermia is a common monotherapy for sporotrichosis, but only in patients with special conditions, such as pregnancy and nursing. However, hyperthermia has not been used more widely for sporotrichosis in clinical practice. PATIENTS/METHODS: An HIV-positive adult male with lymphocutaneous sporotrichosis caused by Sporothrix globosa that did not respond to conventional itraconazole therapy lasting >2 months received adjunctive therapy with local hyperthermia. To simulate the effects of heat exposure on the growth and morphology of Sporothrix spp. in vitro, S. globosa, S. schenckii and S. brasiliensis were exposed to intermittent heat (42°C) for 1 h a day for 7 or 28 days and observed under transmission electron microscopy. RESULTS: Itraconazole combined with local hyperthermia significantly improved the lesions, and the patient was successfully cured of sporotrichosis, with no recurrence after 2 years of follow-up. Cultures of Sporothrix spp. treated with 7 days of daily heat exposure in vitro showed obvious decreases in colony diameters, but not numbers, compared with untreated cultures (p < .001). After 28 days of heat exposure in vitro, Sporothrix spp. were unable to thrive (p < .001), and ultrastructural alterations, including loose cell wall structure, incomplete cell membrane, disrupted vacuoles and fragmented nuclei, were noticeable. CONCLUSIONS: Our case findings and in vitro experiments on Sporothrix spp., together with a literature review of previous sporotrichosis cases, suggest that hyperthermia has a clinical role as a treatment adjunct. Large-scale clinical trials are required to examine the utility of hyperthermia in various forms of cutaneous sporotrichosis.

Research progress on the molecular mechanism of electroacupuncture at "Zusanli" (ST36) for regulating gastrointestinal dysfunction. / 电针"足三里"è°ƒèŠ‚èƒƒè‚ åŠŸèƒ½å¼‚å¸¸çš„åˆ†å­æœºåˆ¶ç ”ç©¶è¿›å±•.

Gastrointestinal dysfunction is manifested as digestive symptoms. Clinically, Zusanli (ST36) is crucial in the acupoint prescriptions of acupuncture no matter which type of the disease is differentiated in traditional Chinese medicine, but the underlying mechanism remains to be explored. Aiming to summarize the current status of the researches in terms of ameliorating gastrointestinal mucosal damage and regulating gastrointestinal motility disorders, we systematically reviewed the basic researches on the intervention with electroacupuncture (EA) at "ST36" in treatment of the diseases related to gastrointestinal dysfunction in the past 5 years, after searching the articles from Chinese and English databases. The results suggest that EA at ST36 may regulate the local gastrointestinal inflammation, oxidative stress and immune microenvironment to relieve gastrointestinal mucosal damage and adjust gastrointestinal motility disorders by means of modulating the central and peripheral nerve signaling as well as the function of mast cells and Cajal interstitial cells.

Amorphous selenium inhibits oxidative stress injury of neurons in vascular dementia rats by activating NMDAR pathway.

Vascular dementia (VD) is one of the most common causes of dementia, taking account for about 20% of all cases. Although studies have found that selenium supplementation can improve the cognitive ability of Alzheimer's patients, there is currently no research on the cognitive impairment caused by VD. This study aimed to investigate the role and mechanism of Amorphous selenium nanodots (A SeNDs) in the prevention of VD. The bilateral common carotid artery occlusion (BCCAO) method was used to establish a VD model. The neuroprotective effect of A SeNDs was evaluated by Morris water maze, Transcranial Doppler TCD, hematoxylin-eosin (HE) staining, Neuron-specific nuclear protein (Neu N) staining and Golgi staining. Detect the expression levels of oxidative stress and Calcium-calmodulin dependent protein kinase II (CaMK II), N-methyl-D-aspartate receptor subunit NR2A, and postsynaptic dense protein 95 (PSD95). Finally, measure the concentration of calcium ions in neuronal cells. The results showed that A SeNDs could significantly improve the learning and memory ability of VD rats, restore the posterior arterial blood flow of the brain, improve the neuronal morphology and dendritic remodeling of pyramidal cells in hippocampal CA1 area, reduce the level of oxidative stress in VD rats, increase the expression of NR2A, PSD95, CaMK II proteins and reduce intracellular calcium ion concentration, but the addition of selective NR2A antagonist NVP-AAMO77 eliminated these benefits. It suggests that A SeNDs may improve cognitive dysfunction in vascular dementia rats by regulating the NMDAR pathway.

[Observation of the therapeutic effect on acute ankle sprain treated with surrounding needling and cold compression].

OBJECTIVE: To observe the difference in the therapeutic effect on acute ankle sprain treated with the combination of surrounding needling and cold compression in comparison of the conventional cold compression. METHODS: The patients with acute ankle sprain were randomly divided into control group (33 cases) and observation group (35 cases). In the first 3 days of treatment, the conventional cold compression was used in the control group, while the surrounding needling technique of acupuncture was combined with cold compression in the observation group. Separately, along the distal-lateral side of the leg, and the lateral sides of the heel and the dorsal part of the foot, 3 or 4 needles were inserted in each part，total 9 to 12 needles, toward the center of swelling and pain site, and distributed in a fan shape. The needles were retained for 30 min and the acupuncture therapy was delivered once daily. Since the 4th day of treatment, the hot compress and the static stretching exercise of the ankle joint were adopted in the two groups, once daily for 1 week. The visual analogue scale (VAS) score for ankle pain and ankle swelling degree were compared between the two groups before and after 3-day treatment, as well as the score of American orthopedic foot and ankle society (AOFAS) ankle-hindfoot scale was evaluated. RESULTS: After 3-day treatment, VAS score was decreased in both groups (P<0.01), and the score in the observation group was lower than that of the control group (P<0.01). Ankle swelling degree was relieved in both groups (P<0.01), and there was no significant difference between the two groups. After 1 week of treatment, the scores of AOFAS ankle-hindfoot scale were improved in both groups (P<0.01), and the score in the observation group was higher than the control group (P<0.05). CONCLUSION: Either the combined therapy of surrounding needling and cold compression or the conventional cold compression can effectively relieve pain and swelling induced by acute ankle sprain. The therapeutic effect of the combined therapy is superior to the conventional cold compression for the motor function improvement of ankle joint.

American ginseng with different processing methods ameliorate immunosuppression induced by cyclophosphamide in mice via the MAPK signaling pathways.

This study aimed to clarify the effects of two processed forms of American ginseng (Panax quinquefolius L.) on immunosuppression caused by cyclophosphamide (CTX) in mice. In the CTX-induced immunosuppressive model, mice were given either steamed American ginseng (American ginseng red, AGR) or raw American ginseng (American ginseng soft branch, AGS) by intragastric administration. Serum and spleen tissues were collected, and the pathological changes in mice spleens were observed by conventional HE staining. The expression levels of cytokines were detected by ELISA, and the apoptosis of splenic cells was determined by western blotting. The results showed that AGR and AGS could relieve CTX-induced immunosuppression through the enhanced immune organ index, improved cell-mediated immune response, increased serum levels of cytokines (TNF-α, IFN-γ, and IL-2) and immunoglobulins (IgG, IgA, and IgM), as well as macrophage activities including carbon clearance and phagocytic index. AGR and AGS downregulated the expression of BAX and elevated the expression of Bcl-2, p-P38, p-JNK, and p-ERK in the spleens of CTX-injected animals. Compared to AGS, AGR significantly improved the number of CD4+CD8-T lymphocytes, the spleen index, and serum levels of IgA, IgG, TNF-α, and IFN-γ. The expression of the ERK/MAPK pathway was markedly increased. These findings support the hypothesis that AGR and AGS are effective immunomodulatory agents capable of preventing immune system hypofunction. Future research may investigate the exact mechanism to rule out any unforeseen effects of AGR and AGS.

[Jianpi Peiyuan acupoint thread embedding therapy for perimenopausal obesity: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy and safety of Jianpi Peiyuan acupoint thread embedding therapy on perimenopausal obesity (PMO). METHODS: Ninety-six patients of PMO were randomly divided into an observation group (48 cases) and a control group (48 cases). The control group received health education and lifestyle intervention. On the basis of the treatment in the control group, the observation group was treated with acupoint thread embedding at the main acupoints of Shangwan (CV 13), Zhongwan (CV 12), Xiawan (CV 10), Yinlingquan (SP 9) and Fenglong (ST 40), etc. as well as the supplementary acupoints in accordance with the syndrome differentiation, once every 2 weeks for 8 weeks (4 times in total). The indexes of obesity (body mass index [BMI], waist circumference, hip circumference and body mass), modified Kupperman score, insomnia severity index (ISI) score, self-rating anxiety scale (SAS) score, and self-rating depression scale (SDS) score of the two groups were observed before and after treatment, and the safety was evaluated. RESULTS: After treatment, BMI, waist circumference, hip circumference and body mass in the two groups were lower than before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). After treatment, Kupperman, ISI and SAS scores in the observation group were lower than before treatment (P<0.05), and ISI score in the control group was lower than before treatment (P<0.05). Kupperman, ISI and SAS scores in the observation group were lower than those in the control group (P<0.05). There was no significant difference in SDS between the two groups or within groups (P>0.05). No serious adverse reactions occurred during the experiment. CONCLUSION: Jianpi Peiyuan acupoint thread embedding therapy can reduce the degree of obesity in PMO patients, and improve patients' the perimenopausal symptoms, insomnia and anxiety, with good safety.

[Effect of acupuncture at Weizhong (BL 40) on bladder urination function based on ultrasound].

OBJECTIVE: To observe the effect of acupuncture at Weizhong (BL 40) with deqi on bladder urination function. METHODS: A total of 60 healthy subjects were randomized into an observation group and a control group, 30 subjects in each group. Under the guidance of ultrasound, acupuncture was applied Weizhong (BL 40) on both sides. In the observation group, the needling depth was reached to the tibial nerve, and lifting-thrusting twirling method was used to induce deqi. In the control group, the needling depth was reached to the superficial fascia, and no manipulation was operated to induce deqi. The needles were retained for 10 min and acupuncture was given once in both groups. The bilateral ureteral ejection frequency and volume of the bladder were observed by ultrasound before and after acupuncture, and the score of clinical evaluation scale of deqi sensation was observed in both groups. RESULTS: After acupuncture, the frequency of bilateral ureteral ejection in the observation group and the bladder volume in the two groups were increased compared before acupuncture (P<0.05), and the frequency of bilateral ureteral ejection, bladder volume and score of clinical evaluation scale of deqi sensation in the observation group were higher than those in the control group (P<0.05, P<0.01). CONCLUSION: Acupuncture at Weizhong (BL 40) with deqi improves the bladder urination function. Ultrasound visualization improves the standardization and safety of acupuncture, intuitively evaluates the acupuncture effect, and provides an objective basis for the correlation between meridian points specificity and zang-fu organs.

Targeted modulation of gut microbiota by traditional Chinese medicine and natural products for liver disease therapy.

The gut microbiota not only constitutes intestinal microenvironment homeostasis and human health but also exerts indispensable roles in the occurrence and progression of multiple liver diseases, including alcohol-related liver disease, nonalcoholic fatty liver disease, autoimmune liver disease and liver cancer. Given the therapeutic status of these diseases, their prevention and early therapy are crucial, and the detailed mechanism of gut microbiota in liver disease urgently needs to be explored. Meanwhile, multiple studies have shown that various traditional Chinese medicines, such as Si Miao Formula, Jiangzhi Granules, Liushen Capsules, Chaihu-Shugan Power, Cassiae Semen and Gynostemma, as well as some natural products, including Costunolide, Coprinus comatus polysaccharide, Antarctic krill oil, Oridonin and Berberine, can repair liver injury, improve fatty liver, regulate liver immunity, and even inhibit liver cancer through multiple targets, links, and pathways. Intriguingly, the aforementioned effects demonstrated by these traditional Chinese medicines and natural products have been shown to be closely related to the gut microbiota, directly driving the strategy of traditional Chinese medicines and natural products to regulate the gut microbiota as one of the breakthroughs in the treatment of liver diseases. Based on this, this review comprehensively summarizes and discusses the characteristics, functions and potential mechanisms of these medicines targeting gut microbiota during liver disease treatment. Research on the potential effects on gut microbiota and the regulatory mechanisms of traditional Chinese medicine and natural products provides novel insights and significant references for developing liver disease treatment strategies. In parallel, such explorations will enhance the comprehension of traditional Chinese medicine and natural products modulating gut microbiota during disease treatment, thus facilitating their clinical investigation and application.

[Application and research progress of ultrasound in acupuncture treatment].

The operation standardization, quantitative standard and safety of acupuncture treatment are important links in the development of acupuncture modernization. In recent years, with the continuous development of ultrasonic imaging technology, ultrasonic medicine has the characteristics of visualization, quantitative analysis and real-time dynamics, which could play a unique role in acupuncture treatment. In this paper, the research progress of the combined application of ultrasonic medicine and acupuncture treatment is described from three aspects: ultrasound guidance helping to standardize acupuncture operation, ultrasound guidance helping to improve and evaluate the clinical efficacy of acupuncture, and ultrasound guidance helping to improve the safety of acupuncture, aiming to providing new ideas for the application of modern medicine in traditional medicine.

Natural borneol enhances the anti-cerebral ischaemia efficacy of formononetin in MCAO/R rats by promoting its delivery in the brain.

Objectives Due to its high morbidity, high mortality, and high disability, stroke has been the first cause of death and the major cause of adult disability in China. Natural borneol has been widely utilized in Traditional Chinese Medicine to promote drug absorption. Formononetin is a natural isoflavonoid with potent neuroprotective activity but poor brain delivery. Methods This study aimed to screen the optimum proportion that natural borneol promotes formononetin entry into the brain, evaluate the anti-cerebral ischaemia efficacy of formononetin/natural borneol combination in middle cerebral artery occlusion/reperfusion model rats, and clarify the possible mechanism for natural borneol's promoting formononetin delivery in the brain. Key findings Our studies exhibited that natural borneol remarkably promoted formononetin entry into the brain when combined with formononetin in a 1 : 1 molar ratio and notably improved neuro-behavioural scores and reduced the infarct of middle cerebral artery occlusion/reperfusion model rats. This study further discovered that the enhanced anti-cerebral ischaemia effect resulted from natural borneol increasing the permeability of the blood-brain barrier to elevate formononetin concentration in the brain rather than the pharmacodynamic synergy or addition between formononetin and natural borneol. Conclusions The study provides a good strategy to screen drug combinations for the treatment of brain disease by combining natural borneol with other drugs.

Clinical efficacy analysis of 110 cases of childhood vitiligo with non-surgical combined therapy.

BACKGROUND: Vitiligo has a negative effect on children's physical and psychological health. Few studies have examined long-term treatment efficacy for childhood vitiligo. Therefore, we evaluated the long-term effectiveness of non-surgical combination therapy in pediatric patients with vitiligo and analyzed factors that affect its efficacy. METHODS: Pediatric patients (⩽12 years) with vitiligo who were treated with topical corticosteroids/topical calcineurin inhibitors and phototherapy for 12 months were retrospectively studied. Short-term systemic corticosteroids were administered according to individual clinical conditions. All lesions were photographed to assess repigmentation at 3-month intervals. Clinical data, the treatment effectiveness, and factors affecting the therapeutic effect were analyzed. RESULTS: Overall, 110 children (51 [53.6%] girls; mean [SD] age, 7.1 ± 3.0 years; 104 [94.5%] with activity status) were treated for a mean period of 23.13 ± 14.03 months (range, 5-86 months). The overall >50% repigmentation rate was 64.5%. A longer duration of treatment was associated with a higher repigmentation rate (X2 trend = 36.229, P < .001). The vitiligo disease activity score at the first visit was positively correlated with the overall repigmentation rate (rs = 0.301, P = .001). CONCLUSIONS: Treatment lasting longer than 1 year is recommended in children with vitiligo. The best repigmentation effect can be achieved by combination therapy in the rapid progression stage.

Panax quinquefolius Polysaccharides Ameliorate Antibiotic-Associated Diarrhoea Induced by Lincomycin Hydrochloride in Rats via the MAPK Signaling Pathways.

American ginseng (Panax quinquefolius L.) is an herbal medicine with polysaccharides as its important active ingredient. The purpose of this research was to identify the effects of the polysaccharides of P. quinquefolius (WQP) on rats with antibiotic-associated diarrhoea (AAD) induced by lincomycin hydrochloride. WQP was primarily composed of galacturonic acid, glucose, galactose, and arabinose. The yield, total sugar content, uronic acid content, and protein content were 6.71%, 85.2%, 31.9%, and 2.1%, respectively. WQP reduced the infiltration of inflammatory cells into the ileum and colon, reduced the IL-1ß, IL-6, IL-17A, and TNF-α levels, increased the levels of IL-4 and IL-10 in colon tissues, improved the production of acetate and propionate, regulated the gut microbiota diversity and composition, improved the relative richness of Lactobacillus and Bacteroides, and reduced the relative richness of Blautia and Coprococcus. The results indicated that WQP can enhance the recovery of the intestinal structure in rats, reduce inflammatory cytokine levels, improve short-chain fatty acid (SCFA) levels, promote recovery of the gut microbiota and intestinal mucosal barrier, and alleviate antibiotic-related side effects such as diarrhoea and microbiota dysbiosis caused by lincomycin hydrochloride. We found that WQP can protect the intestinal barrier by increasing Occludin and Claudin-1 expression. In addition, WQP inhibited the MAPK inflammatory signaling pathway to improve the inflammatory status. This study provides a foundation for the treatment of natural polysaccharides to reduce antibiotic-related side effects.

Curcumin regulates the homeostasis of Th17/Treg and improves the composition of gut microbiota in type 2 diabetic mice with colitis.

Diabetes mellitus (DM) is one of the most common complications in patients with ulcerative colitis (UC). Curcumin has a wide range of bioactive and pharmacological properties and is commonly used as an adjunct to the treatment of UC and DM. However, the role of curcumin in UC complicated by DM has not been elucidated. Therefore, this study was conducted to construct a model of UC complicating diabetes by inducing UC in DB mice (spontaneously diabetic) with dextran sodium sulfate. In this study, curcumin (100 mg/kg/day) significantly improved the symptoms of diabetes complicated by UC, with a lower insulin level, heavier weight, longer and lighter colons, fewer mucosal ulcers and less inflammatory cell infiltration. Moreover, compared to untreated DB mice with colitis, curcumin-treated mice showed weaker Th17 responses and stronger Treg responses. In addition, curcumin regulated the diversity and relative abundance of intestinal microbiota in mice with UC complicated by DM at the phylum, class, order, family and genus levels. Collectively, curcumin effectively alleviated colitis in mice with type 2 diabetes mellitus by restoring the homeostasis of Th17/Treg and improving the composition of the intestinal microbiota.

Sediment formation and analysis of the main chemical components of aqueous extracts from different parts of ginseng roots.

Sediment is a key issue in the production and marketing of plant beverages, as is ginseng beverages. The formation of sediment in ginseng beverages is a gradual process. This work describes the formation of sediment from different parts of ginseng and describes the color and clarity of the liquid and the amount and morphology of the sediment. The results showed there are significant differences in the sediment formation speed, morphology and transmittance for the aqueous extracts prepared from different parts of ginseng. The amounts of sediment generated from the different parts of ginseng is as follows: main root > rhizome > fibrous root. Free amino acids, Ba, Ca, Ni, and Sr concentrations are significantly and positively correlated with the transmittance. The total saponins, Al, Fe, and Mn concentrations are significantly and negatively correlated with the transmittance. There are obvious crystals and more Ca in the fibrous root sediment. We analyzed and compared the chemical components in the sediment and extract. The results show that the main components of the sediment are carbohydrates and protein. According to the partition coefficient the contents of protein, ginsenosides (Rb1, Rb2, Rb3, Rf) and some ions (Al, Fe, Ca, and Na) contribute more to the formation of the sediment than the other investigated components.

Efficacy of different nutrients in age-related macular degeneration: A systematic review and network meta-analysis.

AIM: Age-related macular degeneration (AMD) has become a predominant global health concern. The visual function of individuals with AMD seems to improve with dietary antioxidants. We assessed the efficacy of different antioxidants (carotenoids, zinc, vitamin E, and multivitamin) on visual function and the incidence of developing late AMD. METHODS: We searched PubMed, EMBASE, and Cochrane Central Register of Controlled Trials for related published studies. We considered randomized controlled trials (RCTs) comparing different nutrients. The main outcomes measurements included changes in visual acuity (VA), and the rate of developing late AMD. The network meta-analysis was registered on PROSPERO (CRD42020171288). RESULTS: We identified 13 studies, including 85321 individuals randomly assigned to different nutrients or placebo groups. In the network meta-analysis, we found that there was more risk of progression to late AMD in the multivitamin group than carotenoids and vitamin E groups (RR 0.45, 95% CI 0.32 to 0.65; RR 0.56, 95% CI 0.40 to 0.79; RR 0.42, 95% CI 0.26 to 0.67). The nutrients of zinc and carotenoids (Lutein/Zeaxanthin) ranked first and second and showed better improvement in VA. The efficacy of carotenoids (ß-carotene) ranked first for delaying the progress of AMD among all of the four treatments. CONCLUSION: Taking multivitamin supplementation may not prevent the development of late AMD. The nutrient of zinc and carotenoids (lutein/zeaxanthin) supplementation were associated with better improvement in VA. Carotenoids (ß-carotene) were the most likely to prevent the progression of late AMD.

To evaluate the efficacy and safety of Chinese patent medicines in the treatment of insomnia by frequency network Meta-analysis. Randomized controlled trials of Chinese patent medicines for insomnia were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library databases from the time of database establishment to October 2020. The quality of the included RCTs was evaluated according to the Cochrane bias risk standard, and the data was analyzed by RevMan 5.3 and Stata/MP 15.1. A total of 11 kinds of Chinese patent medicines in 27 RCTs were included. According to Meta-analysis, in term of the effective rate, Tianmeng Liquid, Zaoren Anshen Capsules, Shumian Capsules, Shensong Yangxin Capsules, Shenqi Wuweizi Tablets, Shugan Jieyu Capsules, Anshen Bunao Liquid and Qiye Anshen Tablets combined with nonbenzodiazepine drugs(NBZDs) were superior to NBZDs alone. In term of the improvement of Pittsburg sleeping quality index(PSQI) score, Tianmeng Liquid, Shumian Capsules, Shensong Yangxin Capsules, Bailemian Capsules, Shenqi Wuweizi Tablets, Shugan Jieyu Capsules, Yangxue Qingnao Granules and Yindan Xinnaotong Capsules combined with NBZDs were superior to NBZDs alone. In terms of the safety, Shumian Capsules, Shensong Yangxin Capsules, Shenqi Wuweizi Tablets and Qiye Anshen Tablets combined with NBZDs were superior to NBZDs alone. In terms of the avoidance of dizziness and headache, Qiye Anshen Tablets combined with NBZDs were superior to NBZDs alone. The results of Network Meta-analysis indicated that in term of the effective rate, top three optimal medication regimens were NBZDs combined with Shugan Jieyu Capsules, combined with Zaoren Anshen Capsules and combined with Shensong Yangxin Capsules in the order from high to low. With the respect of improvement of PSQI score, top three optimal medication regimens were NBZDs combined with Yangxue Qingnao Granules, combined with Tianmeng Liquid and combined with Yindan Xinnaotong Capsules in the order from high to low. In terms of the safety, top three optimal medication regimens were NBZDs combined with Qiye Anshen Tablets, combined with Shensong Yangxin Capsules and combined with Shenqi Wuweizi Tablets in the order from high to low. In terms of the avoidance of dizziness and headache, top three optimal medication regimens were NBZDs combined with Qiye Anshen Tablets, combined with Zaoren Anshen Capsules and combined with Shumian Capsules in the order from high to low. In terms of the avoidance of fatigue, top three optimal medication regimens were NBZDs combined with Shensong Yangxin Capsules, combined with Shumian Capsules and combined with Qiye Anshen Tablets in the order from high to low. In conclusion, Chinese patent medicines combined with NBZDs can effectively alleviate the symptoms of insomnia with a high safety. However, the conclusion of this study needs to be verified by more high-quality studies because of the low methodological quality of the included studies.

Targeting the Wnt/ß-Catenin Signaling Pathway as a Potential Therapeutic Strategy in Renal Tubulointerstitial Fibrosis.

The Wnt/ß-catenin signaling pathway plays important roles in embryonic development and tissue homeostasis. Wnt signaling is induced, and ß-catenin is activated, associated with the development and progression of renal fibrosis. Wnt/ß-catenin controls the expression of various downstream mediators such as snail1, twist, matrix metalloproteinase-7, plasminogen activator inhibitor-1, transient receptor potential canonical 6, and renin-angiotensin system components in epithelial cells, fibroblast, and macrophages. In addition, Wnt/ß-catenin is usually intertwined with other signaling pathways to promote renal interstitial fibrosis. Actually, given the crucial of Wnt/ß-catenin signaling in renal fibrogenesis, blocking this signaling may benefit renal interstitial fibrosis. There are several antagonists of Wnt signaling that negatively control Wnt activation, and these include soluble Fzd-related proteins, the family of Dickkopf 1 proteins, Klotho and Wnt inhibitory factor-1. Furthermore, numerous emerging small-molecule ß-catenin inhibitors cannot be ignored to prevent and treat renal fibrosis. Moreover, we reviewed the knowledge focusing on anti-fibrotic effects of natural products commonly used in kidney disease by inhibiting the Wnt/ß-catenin signaling pathway. Therefore, in this review, we summarize recent advances in the regulation, downstream targets, role, and mechanisms of Wnt/ß-catenin signaling in renal fibrosis pathogenesis. We also discuss the therapeutic potential of targeting this pathway to treat renal fibrosis; this may shed new insights into effective treatment strategies to prevent and treat renal fibrosis.

Thermal-sensitive lipid nanoparticles potentiate anti-PD therapy through enhancing drug penetration and T lymphocytes infiltration in metastatic tumor.

The response rate of anti-PD therapy in most cancer patients remains low. Therapeutic drug and tumor-infiltrating lymphocytes (TILs) are usually obstructed by the stromal region within tumor microenvironment (TME) rather than distributed around tumor cells, thus unable to induce the immune response of cytotoxic T cells. Here, we constructed the cationic thermosensitive lipid nanoparticles IR780/DPPC/BMS by introducing cationic NIR photosensitizer IR-780 iodide (IR780) modified lipid components, thermosensitive lipid DPPC and PD-1/PD-L1 inhibitor BMS202 (BMS). Upon laser irradiation, IR780/DPPC/BMS penetrated into deep tumor, and reduced cancer-associated fibroblasts (CAFs) around tumor cells to remodel the spatial distribution of TILs in TME. Interestingly, the cationic IR780/DPPC/BMS could capture released tumor-associated antigens (TAAs), thereby enhancing the antigen-presenting ability of DCs to activate cytotoxic T lymphocytes. Moreover, IR780/DPPC/BMS initiated gel-liquid crystal phase transition under laser irradiation, accelerating the disintegration of lipid bilayer structure and leading to the responsive release of BMS, which would reverse the tumor immunosuppression state by blocking PD-1/PD-L1 pathway for a long term. This combination treatment can synergistically exert the antitumor immune response and inhibit the tumor growth and metastasis.

[Toosendanin induces apoptosis of human gastric cancer MGC-803 cells and its mechanism].

Objective: To explore the apoptosis of human gastric cancer MGC-803 cells induced by toosendanin(TSN) and its mechanism. Methods: The human gastric cancer MGC-803 cells were divided into 5 groups, each group was set with 3 replicate. Fluorouracil (5-FU) and 0 nmol/L toosendanin (TSN) were used as positive control and negative control, respectively. The other three groups were treated with toosendanin at the final concentrations of 30, 50, and 70 nmol/L, respectively. After 48 h of treatment with toosendanin, the morphology of the cells were observed under laser confocal microscopy. Flow cytometry was used to detect the mitochondrial membrane potential, and enzyme-labeled assays were used to detect the activities of Caspase-3 and Caspase-9. The mRNA and protein levels of Bcl-2, Bax, Cyt c and APAF-1 were measured by qRT-PCR and Western blot. Results: Compared with the 0 nmol/L TSN group, after the human gastric cancer MGC-803 cells were treated with toosendanin at the concentrations of 30, 50, and 70 nmol/L for 48 h, the cell volume shrinkage, nucleus cleavage and chromatin morphological changes were observed under the microscope. The activities of Caspase-3 and Caspase-9 were increased significantly (P＜0.05), while the mitochondrial membrane potential was decreased significantly (P＜0.05). In addition, the mRNA and protein expression levels of Bax, Cyt c and APAF-1 were increased significantly (P＜0.05), while the mRNA and protein expression levels of Bcl-2 were decreased significantly (P＜0.05). Conclusion: Toosendanin up-regulates the expressions of Bax, Cyt c and APAF-1, down-regulates the expression of Bcl-2 gene, enhances the activities of caspase-3 and caspase-9, and induces the apoptosis of human gastric cancer MGC-803 cells.
