Secondary metabolites isolated from Trichoderma hamatum b-3 and their fungicidal activity.

An undescribed trichodenone derivative (1), two new diketopiperazines (3 and 4) along with a bisabolane analog (2) were isolated from Trichoderma hamatum b-3. The structures of the new findings were established through comprehensive analyses of spectral evidences in HRESIMS, 1D and 2D NMR, Marfey's analysis as well as comparisons of ECD. The absolute configuration of 2 was unambiguously confirmed by NMR, ECD calculation and Mo2(AcO)4 induced circular dichroism. Compounds 1-4 were tested for their fungicidal effects against eight crop pathogenic fungi, among which 1 showed 51% inhibition against Sclerotinia sclerotiorum at a concentration of 50 µg/mL.

Salvianolic acid B ameliorates retinal deficits in an early-stage Alzheimer's disease mouse model through downregulating BACE1 and Aß generation.

Alzheimer's disease (AD) is a neurodegenerative disease with subtle onset, early diagnosis remains challenging. Accumulating evidence suggests that the emergence of retinal damage in AD precedes cognitive impairment, and may serve as a critical indicator for early diagnosis and disease progression. Salvianolic acid B (Sal B), a bioactive compound isolated from the traditional Chinese medicinal herb Salvia miltiorrhiza, has been shown promise in treating neurodegenerative diseases, such as AD and Parkinson's disease. In this study we investigated the therapeutic effects of Sal B on retinopathy in early-stage AD. One-month-old transgenic mice carrying five familial AD mutations (5×FAD) were treated with Sal B (20 mg·kg-1·d-1, i.g.) for 3 months. At the end of treatment, retinal function and structure were assessed, cognitive function was evaluated in Morris water maze test. We showed that 4-month-old 5×FAD mice displayed distinct structural and functional deficits in the retinas, which were significantly ameliorated by Sal B treatment. In contrast, untreated, 4-month-old 5×FAD mice did not exhibit cognitive impairment compared to wild-type mice. In SH-SY5Y-APP751 cells, we demonstrated that Sal B (10 µM) significantly decreased BACE1 expression and sorting into the Golgi apparatus, thereby reducing Aß generation by inhibiting the ß-cleavage of APP. Moreover, we found that Sal B effectively attenuated microglial activation and the associated inflammatory cytokine release induced by Aß plaque deposition in the retinas of 5×FAD mice. Taken together, our results demonstrate that functional impairments in the retina occur before cognitive decline, suggesting that the retina is a valuable reference for early diagnosis of AD. Sal B ameliorates retinal deficits by regulating APP processing and Aß generation in early AD, which is a potential therapeutic intervention for early AD treatment.

Transcriptomic and network pharmacology approaches revealed possible mechanisms underlying the 5-fluorouracil (5-FU)-sensitizing effect of Xuan-Fu-Hua decoction treatment on liver cancer cells.

Background: Xuan-Fu-Hua decoction is a traditional Chinese medicine formula widely used for the treatment of inflammation-related disease in the lung and liver. This study aimed to investigate the effect of Xuan-Fu-Hua decoction treatment on liver cancer cells and its mechanism of action. Methods: The impact of Xuan-Fu-Hua decoction treatment on the proliferation and apoptosis of SMMC-7721 liver cancer cells with or without 5-fluorouracil (5-FU) cotreatment was determined in both in vitro and in vivo settings. Alterations in gene expression patterns in SMMC-7721 cells induced by Xuan-Fu-Hua decoction treatment were explored by transcriptomic sequencing. Effective components of Xuan-Fu-Hua decoction and their target proteins were investigated using network pharmacology approaches. Results: Xuan-Fu-Hua decoction alone did not significantly influence SMMC-7721 liver cancer cell growth, but it significantly increased the 5-Fu-induced growth inhibition and apoptosis of SMMC-7721 liver cancer cells in vitro and in vivo. Most differentially expressed genes in SMMC-7721 liver cancer cells with or without Xuan-Fu-Hua decoction treatment were enriched in cell apoptosis-related pathways. Xuan-Fu-Hua decoction treatment significantly increased the transcription levels of DDIT3, PMAIP1, and ZMAT3 genes while decreasing that of WNT4, AXIN2, NFE2L2, TGFBR1, MITF, and IGFBP3 genes. An interaction network between the effective components and their possible target proteins was constructed by predicting compound-target protein and protein-protein interactions. Gene set enrichment analysis revealed the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway as well as Bcl-2 and Mcl-1 proteins as potential regulatory targets of Xuan-Fu-Hua decoction in sensitizing SMMC-7721 cells to the cytotoxicity of 5-FU treatment. Conclusions: Xuan-Fu-Hua decoction increased the sensitivity of liver cancer cells to the cytotoxicity of 5-FU treatment, possibly by potentiating cell apoptosis and inhibiting the prosurvival machinery.

The efficacy and safety of acupuncture assisted anesthesia (AAA) for postoperative pain of thoracoscopy: A protocol for systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Enhanced recovery after surgery suggests the use of multimodal analgesia to optimize the perioperative pain management scheme. At present, studies have shown that the application of acupuncture combined anesthesia in thoracoscopy has achieved good curative effect. However, there is no relevant systematic evaluation. Our study is the first meta-analysis of the effectiveness and safety of acupuncture combined anesthesia in pain management after thoracoscopy, in order to provide strong evidence for clinical support. METHODS: A comprehensive and systematic literature searching will mainly perform on 7 electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, and WanFang Data, Chinese Biomedical Database) from their inception up to November 30, 2021. We will also search for ongoing or unpublished studies from other websites (eg, PROSPERO, ClinicalTrials.gov, Chinese Clinical Trial Registry) and do manual retrieval for potential gray literature. Only the relevant randomized controlled trials published in English or Chinese were included. Two independent investigators will independently complete literature selection, assessment of risk bias, and data extraction, the disagreements will be discussed with the third party for final decisions. The primary outcome measures: visual analog scale, intraoperative anesthetic dosage, and the consumption of postoperative analgesics. The secondary outcome measures: Pittsburgh Sleep Quality Index, the total sleep time after operation, residence time in the anesthesia recovery room, the duration of hospitalization, and the incidence of adverse reactions and serious events. Assessment of bias risk will follow the Cochrane risk of bias tool. Data processing will be conducted by Stata 15.0 software. RESULTS: We will evaluate the efficacy and safety of acupuncture assisted anesthesia for postoperative pain after thoracoscopy based on randomized controlled trials. CONCLUSION: This study can provide more comprehensive and strong evidence whether acupuncture assisted anesthesia is efficacy and safe for postoperative pain in thoracoscopy. REGISTRATION: The research has been registered and approved on the INPLASY website. The registration number is INPLASY 2021120129.

Efficacy and Safety of Transcutaneous Electrical Acupoint Stimulation (TEAS) for Postoperative Pain in Laparoscopy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: This meta-analysis aimed to assess the efficacy and safety of transcutaneous acupoint electrical stimulation (TEAS) for postoperative pain in laparoscopy. The review has been registered on the "INPLASY" website and the registration number is INPLASY202150101. METHODS: Relevant randomized controlled trials are selected from seven electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, WanFang Data, and Chinese Biomedical Database) from their inception up to November 30, 2020. Twenty-eight studies were included in this meta-analysis, and the statistical analyses and the exploration of heterogeneity sources were conducted by Stata 15.0 software. Besides, the bias assessment of the included studies was evaluated using the Cochrane risk of bias tool. RESULTS: In total, 28 RCTs covering 2787 participants were included. The meta-analysis suggested that TEAS can effectively relieve pain in the short term after laparoscopy, reduce the postoperative consumption of rescue analgesics, improve the quality of life of patients, and shorten the length of hospitalization. And no serious adverse events are related to TEAS. Therefore, TEAS is relatively safe and efficacy for clinical application. The most used acupoints were Hegu (LI14), Neiguan (PC6), and Zusanli (ST36). CONCLUSIONS: TEAS can be recommended as a complementary and alternative therapy for the treatment of postoperative pain after laparoscopy. However, the included RCTs had some methodological limitations. Therefore, larger-size, more rigorous, and higher-quality RCTs are needed in the future to further explore the efficacy and safety of TEAS for postoperative pain after laparoscopy.

[Discussion on the theory of he-sea point in Neijing (Inner Canon of Yellow Emperor) and Nanjing (Yellow Emperor's Classic of Eighty-one Difficult Issues )].

By collecting and analyzing the explanation/conception, acupoint name, acupoint location, indications, acupuncture and moxibustion techniques and contraindications of he-sea point recorded in Neijing (Inner Canon of Yellow Emperor) and Nanjing (Yellow Emperor 's Classic of Eighty-one Difficult Issues), it is found that conception of he-sea point of five-shu points has been specifically formed, the names of he-sea points of eleven meridians, the locations and the ways to locate them were recorded. But, the summaries relevant to the indications of the many he-sea points have not been included in teaching materials, thus, it needs to be further analyzed. The acupuncture-moxibustion techniques at he-sea point are flexible and the attention should be paid to distinguish "needling he-sea point in autumn" from "needling he-sea point in winter". Besides, the consideration should be given on coma/fainting induced by arterial bleeding when needling he-sea point, as well as the joint motor impairment caused by over deep insertion in acupuncture.

The efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) for postoperative pain in laparoscopy: A protocol for systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: With the promotion of the concept of "minimally invasive" surgery, the advantages of laparoscopic surgery are increasingly manifested. However, the postoperative pain of laparoscopic surgery brings difficulties and challenges to patients' rehabilitation. Transcutaneous electrical acupoint stimulation (TEAS) is a non-invasive treatment, which can exert the dual efficacy of acupuncture and electrical stimulation. The efficacy and safety of TEAS for postoperative pain after laparoscopy based on randomized controlled trials (RCTs) need to further evaluate. METHODS: A comprehensive and systematic literature searching will mainly perform on 7 electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, WanFang Data, and Chinese Biomedical Database) from their inception up to November 30, 2020. We will also search for ongoing or unpublished studies from other websites (eg, PROSPERO, ClinicalTrials.gov, and Chinese Clinical Trial Registry) and do manual retrieval for potential gray literature. Only the relevant RCTs published in English or Chinese were included. Two independent investigators will independently complete literature selection, assessment of risk bias, and data extraction, the disagreements will be discussed with the third party for final decisions. The primary outcome measures: the pain intensity (eg, VAS) and the consumption of postoperative analgesics. The secondary outcome measures: the postoperative quality of life, the duration of hospitalization, and the incidence of adverse reactions and serious events. Assessment of bias risk will follow the Cochrane risk of bias tool. Data processing will be conducted by Stata 15.0 software. RESULTS: We will evaluate the efficacy and safety of TEAS for postoperative pain after laparoscopy based on RCTs. CONCLUSION: This study can provide more comprehensive and strong evidence of whether TEAS is efficacy and safe for postoperative pain in laparoscopic surgery.

Acupuncture for patients recovering from lacunar infarction: A protocol for systematic review and meta-analysis.

BACKGROUND: Lacunar infarction (LI) is the mild type in the classification of ischemic stroke, mostly occurs in the middle-aged and elderly, with mild hemiplegia and partial sensory disorder as the main manifestations. In the treatment of LI, acupuncture is often regarded as dominant therapy in the convalescence period. However, acupuncture for treatment of LI in the recovery period lacks high-quality reports and evidence-based medical evidence. Thus, we aim to evaluate the curative effect and safety of acupuncture for LI objectively. METHODS: Pubmed, Cochrane Library, Web of Science, EBSCO, Springer, China National Knowledge Infrastructure, Chinese Scientific and Technical Journals Database (VIP), Wan-fang Database, Chinese Biomedical Literature Database, Chinese Science Citation Database, and other electronic databases will be retrieved from the inception to May, 2021. Randomized controlled trials related to this subject will be searched. The inclusion criteria are established and a detailed literature search strategy is designed through discussion. Article retrieval, screening, excluding repetitive studies, assessment of quality, and data processing will be conducted by 2 reviewers independently using EndNote (X9) and Review Manager (5.3.5). The outcome measures include primary outcome measures (total effective rate, National Institute of Health Stroke Scale score, and Fugl-Meyer Assessment score), secondary outcome measures (blood pressure, plasma glucose, and blood lipid), and safety outcome measures. We will perform a meta-analysis, descriptive analysis, and subgroup analysis based on data conditions. RESULTS: The study of total effective rate, National Institute of Health Stroke Scale score, Fugl-Meyer Assessment score, blood pressure, plasma glucose, blood lipid, and adverse effects will provide evidenced outcome for high-quality synthesis and descriptive analysis. CONCLUSION: This systematic review will kindly provide evidence of whether acupuncture is an effective and safe intervention for LI in the recovery period.

Accelerated screening of arsenic and selenium fractions and bioavailability in fly ash by microwave assistance.

Huge amounts of fly ash (FA) can be annually produced in power plants. Fly ash always contains high levels of arsenic (As) and selenium (Se) due to the preconcentration of these two elements during coal combustion process. It would be much concerned to screen their fractions and potential environmental behaviors in fly ash for beneficial use and treatment. Fast and practical methods for this purpose are urgently needed. Two fast and effective microwave-assisted sequential extraction schemes (MASE) were developed for fast screening As and Se fractions in fly ash for the first time. The extraction parameters including microwave irradiation time, temperature and power energy were optimized by comparing the results from MASE and the conventional scheme (Wenzel method). The results indicate that the extraction efficiency of As and Se in various fractions can be significantly accelerated by microwave irradiation. The whole procedure operation time can be significantly reduced from 24.5 h to 44 min by microwave assistance compared with the conventional shaking schemes. The recoveries of As and Se in the various extracted fractions were all above 80% with relative standard deviations (RSDs) below 8%. The developed methods were further confirmed by the validation of the certified reference material GBW08401 and fly ash samples from six power plants. The developed MASE methods are practical and effective for fast screening arsenic and selenium fractions in fly ash samples.

Manual Acupuncture or Combination with Vitamin B to Treat Diabetic Peripheral Neuropathy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

METHODS: Randomized controlled trials on manual acupuncture treatment of DPN were retrieved from the Medline, Web of Science, PubMed, Cochrane Library, EMBASE, CNKI, WanFang, and VIP databases. Extracted research data were summarized in the tables, and methodological assessment was performed using the risk-of-bias assessment tool of Cochrane. Meta-analysis was performed by Revman 5.3, Stata 14.0, and TSA 0.9.5.10 Beta software. RESULTS: A total of 18 randomized clinical trials (RCTs) were recruited: (1) 11 RCTs were acupuncture alone compared with vitamin B; (2) 7 RCTs were acupuncture combined with vitamin B compared with vitamin B, involving 1200 participants. Acupuncture alone improved clinical efficacy (P < 0.05) and nerve conduction velocity of the four peripheral nerves: peroneal nerve, tibial nerve, median nerve, and ulnar nerve (P < 0.05), but there was no significant difference between the group of acupuncture alone and the group of vitamin B (P = 0.36 > 0.05) in improving median nerve SCV (sensory nerve conduction velocity). Acupuncture combined with vitamin B improved clinical efficacy and nerve conduction velocity of the three peripheral nerves, peroneal nerve, tibial nerve, and median nerve (P < 0.05), and decreased the scores of the Toronto clinical scoring system (TCSS) (P < 0.05). CONCLUSION: Acupuncture alone and vitamin B combined with acupuncture are more effective in treating DPN compared to vitamin B. However, more high-quality RCTs on vitamin B combined with acupuncture are required to confirm our results.

Co-Delivery of Curcumin and Paclitaxel by "Core-Shell" Targeting Amphiphilic Copolymer to Reverse Resistance in the Treatment of Ovarian Cancer.

BACKGROUND: Ovarian cancer is a common malignancy in the female reproductive system with a high mortality rate. The most important reason is multidrug resistance (MDR) of cancer chemotherapy. To reduce side effects, reverse resistance and improve efficacy for the treatment of ovarian cancer, a "core-shell" polymeric nanoparticle-mediated curcumin and paclitaxel co-delivery platform was designed. METHODS: Nuclear magnetic resonance confirmed the successful grafting of polyethylenimine (PEI) and stearic acid (SA) (PEI-SA), which is designed as a mother core for transport carrier. Then, PEI-SA was modified with hyaluronic acid (HA) and physicochemical properties were examined. To understand the regulatory mechanism of resistance and measure the anti-tumor efficacy of the treatments, cytotoxicity assay, cellular uptake, P-glycoprotein (P-gp) expression and migration experiment of ovarian cancer cells were performed. In addition, adverse reactions of nanoformulation to the reproductive system were examined. RESULTS: HA-modified drug-loaded PEI-SA had a narrow size of about 189 nm in diameters, and the particle size was suitable for endocytosis. The nanocarrier could target specifically to CD44 receptor on the ovarian cancer cell membrane. Co-delivery of curcumin and paclitaxel by the nanocarriers exerts synergistic anti-ovarian cancer effects on chemosensitive human ovarian cancer cells (SKOV3) and multi-drug resistant variant (SKOV3-TR30) in vitro, and it also shows a good anti-tumor effect in ovarian tumor-bearing nude mice. The mechanism of reversing drug resistance may be that the nanoparticles inhibit the efflux of P-gp, inhibit the migration of tumor cells, and curcumin synergistically reverses the resistance of PTX to increase antitumor activity. It is worth noting that the treatment did not cause significant toxicity to the uterus and ovaries with the observation of macroscopic and microscopic. CONCLUSION: This special structure of targeting nanoparticles co-delivery with the curcumin and paclitaxel can increase the anti-tumor efficacy without increasing the adverse reactions as a promising strategy for therapy ovarian cancer.

[Observation on time-effect for the stimulating at Zusanli (ST 36) with minimally invasive embedding with PGLA in the healthy person].

OBJECTIVE: To explore the objectivity and time-effect of stimulating effect at acupoint with PGLA in the healthy person, and to provide a basis for the rational interval of minimally invasive embedding of PGLA. METHODS: Before embedding, 8 h, 3rd, 7th, 10th, 14th day after embedding, medical imaging magnetic resonance imaging (MRI) scanning technique was used to collect local T2WI pressure-lowering and T2-Mapping 8 echoes sequence image of left Zusanli (ST 36) in 8 cases of healthy person. The T2-Mapping 8 echoes sequence image was generated by the relevant software to the T2-Mapping image and the local T2 value was measured. The characteristics of local T2WI pressure-fat image signal intensity and the change of T2 value at left Zusanli (ST 36) with minimally invasive embedding with PGLA were observed and analyzed. RESULTS: ①There was no abnormal signal on the T2WI pressure-fat image on the left Zusanli (ST 36) point before the embedding. The high-signal was seen on the local T2WI pressure-fat image at each time point after embedding, there was no significant difference in local signal intensity between 8 h, 3rd and 7th day after embedding. The local signal intensity decreased on the 10th day after embedding, and the local signal intensity decreased significantly on the 14th day after embedding.②The T2 value at each time point after embedding increased significantly compared with that before embedding (all P<0.01); there was no significant difference in T2 value among the 8 h, 3rd and 7th day after embedding (all P>0.05); there was no significant difference between the T2 value on the 7th and the 10th day after embedding (P>0.05)，the T2 value on the 14th day after embedding was significantly lower than that on the 7th day after embedding (P<0.01). CONCLUSION: It has a stimulating effect on the local acupoints with minimally invasive embedding with PGLA in the healthy person, and the stimulating effect has certain time-effect. The effective stimulation time is about 2 weeks. The rational interval period for the minimally invasive embedding with the PGLA of the same specification type should be about 2 weeks.

[The including and recommendation of acupuncture in NGC and NICE].

The diseases recommended to be treated by acupuncture and the recommendation in the National Guideline Clearinghouse (NGC) and the National Institute for Health and Care Excellence (NICE) were summarized, and the diseases recommended were analyzed. The guidelines which mentioned acupuncture in NICE and NGC were searched and classified according to the types of diseases and intensity of recommendations. As a result, 45 guidelines in NGC were included, involving 59 recommendations; 29 guidelines in the NICE, involving 29 recommendations. The diseases recommended by NICE and NGC were mainly pain-related diseases, and the diseases recommended by NGC were wider. However, both needed to further describe the specific operation methods of acupuncture.

Values of applying white blood cell counts in the prognostic evaluation of resectable colorectal cancer.

The count and classification of white blood cells (WBCs) may be used as prognostic markers in certain types of cancer. The present study investigated the prognostic potential of the counts of WBCs, including lymphocytes (LYs), monocytes (MOs), neutrophils (NEs), eosinophils (EOs) and basophils (BAs), in the prognosis of resectable colorectal cancer. The present study recruited 153 resectable colorectal cancer cases retrospectively, which were pathologically confirmed. All patients were divided into two groups, according to the median value of LY (low LY, ≤1.632x109/l or high LY, >1.632x109/l), MO (low MO, ≤0.330x109/l or high MO, >0.330x109/l), NE (low NE, ≤3.600x109/l or high NE, >3.600x109/l), EO (low EO, ≤0.085x109/l or high EO, >0.085x109/l), BA (low BA, ≤0.010x109/l or high BA, >0.010x109/l), or WBC (low WBC, ≤5.780x109/l or high WBC, >5.780x109/l). To evaluate the alterations in WBC counts following surgery and adjuvant chemotherapy; all samples received oxiplatin and capecitabine (XELOX) for 6­8 cycles or 5­fluorouracil, leucovorin and oxaliplatin (mFOLFOX6) for 10­12 cycles. XELOX included oxaliplatin administered intravenously at a dose of 130 mg/m2 on day 1 and 850­1,250 mg/m2 capecitabine twice daily for days 1­14, repeated every 3 weeks. mFOLFOX6 included oxaliplatin administered intravenously at a dose of 85 mg/m2, 400 mg/m2 leucovorin and 400 mg/m2 5­FU on day 1 followed by 1,200 mg/m2/days continuous infusion for 2 days (in total, 2,400 mg/m2 over 46­48 h), repeated every 2 weeks. The present study investigated the post/pre­treatment of LY, MO, NE, EO, BA and WBC ratios (≤1 indicated that LY, MO, NE, EO, BA and WBC counts were not increased following therapy; whereas, >1 suggested increased counts). Kaplan­Meier curves were constructed to demonstrate overall survival (OS). A multivariate and univariate logistic regression analyses model was employed to identify the independent risk factors. Low pre­treatment BA counts were associated with larger tumor size (>5 cm); pre­treatment BA levels were positively associated with OS. Surgery significantly decreased the count of BAs and increased the count of EOs; whereas, no effect was observed on LYs, MOs, NEs or WBCs. Adjuvant chemotherapy markedly decreased the counts of LY, NE and WBC; whereas, no notable effects on MOs, EOs or BAs were observed. Whole course treatment (surgery combined with adjuvant chemotherapy) significantly decreased the values of LY, NE and WBC; however, increased the value of EO; no effects on the MO or BA counts were observed. An increased post­/pre­treatment NE ratio suggested poorer prognosis. Multivariate Cox regression analysis revealed that sex, tumor size, pre­treatment BA count and the post­/pre­treatment NE ratio were independent prognostic factors affecting OS. The results of the present study suggested that the pre­treatment BA count and post­/pre­treatment NE ratio may be potential prognostic factors for resectable colorectal cancer.

Combined Treatment with Autologous CIK Cells, Radiotherapy and Chemotherapy in Advanced Cervical Cancer.

To investigate the clinical efficacy of autologous cytokine induced killer (CIK) cells transfusion combined with radiochemotherapy in the treatment of advanced cervical cancer. A total of 89 hospitalized patients with advanced cervical cancer were admitted and divided into the treatment group (44 cases, autologous CIK cells transfusion combined with radiochemotherapy) and the control group (45 cases, radiochemotherapy) by a randomized non-blind method. Comparisons of therapeutic efficacies, immune functions, life qualities and survival rates were analyzed between the two groups. The short-term therapeutic efficacy of the treatment group was significantly higher than that of the control group. There was no significant difference in 1, 2 and 3 year survival rates between the two groups. Compared with pre-treatment, levels of CD3+, CD4+/CD8+ in peripheral blood were increased in the CIK group, which were reduced in the control group. In the CIK group,only the feeling was depressed on the 25th day post-treatment (T25) compared with the day before treatment (B1). However in the control group, the function of body, role, social and holistic health was obvious disordered on day T25 compared with day B1. On day T25, there were significant differences in function of body, social and holistic health between two groups. Autologous CIK cells transfusion combined with radiochemotherapy shows better short-term efficacy than radiochemotherapy alone in the treatment of advanced cervical cancer, which obviously improves immune function and life quality of patients with low side effects.

Berberine-Promoted CXCR4 Expression Accelerates Endothelial Repair Capacity of Early Endothelial Progenitor Cells in Persons with Prehypertension.

OBJECTIVE: To evaluate whether the berberine treatment can improve endothelial repair capacity of early endothelial progenitor cells (EPCs) from prehypertensive subjects through increasing CXC chemokine receptor 4 (CXCR4) signaling. METHODS: EPCs were isolated from prehypertensive and healthy subjects and cultured. In vivo reendothelialization capacity of EPCs from prehypertensive patients with or without in vitro berberine treatment was examined in a nude mouse model of carotid artery injury. The protein expressions of CXCR4/Janus kinase-2 (JAK-2) signaling of in vitro EPCs were detected by Western blot analysis. RESULTS: CXCR4 signaling and alteration in migration and adhesion functions of EPCs were evaluated. Basal CXCR4 expression was significantly reduced in EPCs from prehypertensive patients compared with normal subjects (P<0.01). Also, the phosphorylation of JAK-2 of EPCs, a CXCR4 downstream signaling, was significantly decreased (P<0.01). Berberine promoted CXCR4/JAK-2 signaling expression of in vitro EPCs (P<0.01). Transplantation of EPCs pretreated with berberine markedly accelerated in vivo reendothelialization (P<0.01). The increased in vitro function and in vivo reendothelialization capacity of EPCs were inhibited by CXCR4 neutralizing antibody or pretreatment with JAK-2 inhibitor AG490, respectively (P<0.01). CONCLUSION: Berberinemodified EPCs via up-regulation of CXCR4 signaling contributes to enhanced endothelial repair capacity in prehypertension, indicating that berberine may be used as a novel potential primary prevention means against prehypertension-related atherosclerotic cardiovascular disease.

Antioxidant Protection of Nobiletin, 5-Demethylnobiletin, Tangeretin, and 5-Demethyltangeretin from Citrus Peel in Saccharomyces cerevisiae.

Aging and oxidative-related events are closely associated with the oxidative damages induced by excess reactive oxygen species (ROS). The phytochemicals nobiletin (NBT) and tangeretin (TAN) and their 5-demethylated derivatives 5-demethylnobiletin (5-DN) and 5-demethyltangeretin (5-DT) are the representative polymethoxyflavone (PMF) compounds found in aged citrus peels. Although the health benefits from PMFs due to their antioxidant activities have been well documented, a systematic assessment regarding the antioxidation process of PMFs is still lacking attention. Herein, we investigated the effects of the four PMFs subjected to oxidative stress including hydrogen peroxide, carbon tetrachloride, and cadmium sulfate using an emerging model organism Saccharomyces cerevisiae. As expected, all four of the PMFs exhibited improved cellular tolerance with decreasing lipid peroxidation and ROS. Furthermore, by using the mutant strains deficient in catalase, superoxide dismutase, or glutathione synthase, NBT, 5-DN, and TAN appear to contribute to the increased tolerance by activating cytosolic catalase under CCl4, while the antioxidant protection conferred by 5-DT against H2O2 and CdSO4 seems to require cytosolic catalase and glutathione, respectively. However, the involvement of Ctt1 and Sod1 is achieved neither by decreasing lipid peroxidation nor by scavenging intracellular ROS according to our results. In addition, a comparison of antioxidant capability of the four PMFs was conducted in this study. In general, this research tries to explore the antioxidant mechanism of PMFs in Saccharomyces cerevisiae, hoping to provide an example for developing more efficacious dietary antioxidants to battle against oxidative- or age-related illness.
