Efficacy and Safety of Huachansu as an Adjuvant Therapy for Non-Small Cell Lung Cancer: An Overview of Systematic Reviews and Meta-Analyses.

OBJECTIVE: The purpose of this overview is to assess systematic reviews (SRs)/ meta-analyses (MAs) of Huachansu (HCS) combination chemotherapy for treating non-small cell lung cancer (NSCLC) and provide summarized evidence for clinical decision making. METHODS: From the creation of the database to JUNE 2023, 8 databases in English and Chinese were searched. SRs/MAs that met the inclusion and exclusion criteria were included. Two reviewers independently screened research, extracted data and assessed methodological quality, risk of bias, report quality and evidence quality by using relevant criteria from AMSTAR-2, ROBIS scale, PRISMA, and GRADE system. RESULTS: The short-term effect, long-term effect, quality of life improvement, safety and pain relief effect in 8 included SRs/MAs were assessed in this overview according to quantitative synthesis. Results assessed by AMSTAR-2, PRISMA, and ROBIS were generally unsatisfactory, with the results of the AMSTAR-2 assessment showing that all of them were of low or critically low quality; the number of items in the included research that were fully reported (compliance was 100%) by the PRISMA checklist was only 50%, while there were 38.10% of the research reporting less than 60% completeness; the ROBIS assessment showed a small number of systems to be low risk of bias. In addition, 26 items were rated as moderate quality, while 50.94% of items were rated as low or critically low quality by GRADE. CONCLUSION: HCS may be a promising adjuvant therapy for NSCLC. However, high-quality SRs/MAs and randomized control trials (RCTs) should be conducted to provide sufficient evidence so as to draw a definitive conclusion.

A Meta-Analysis of the Effects of Levosimendan on Cardiac Function and Outcomes in Patients with Sepsis.

Objective: To systematically evaluate the effect of levosimendan on cardiac function and outcomes in patients with sepsis. Method: We searched multiple databases including CNKI, VIP, WanFang Data, WOS, PubMed, EMbase, and The Cochrane Library up to February 2023. We targeted RCTs comparing levosimendan with dobutamine as a control for treating sepsis. After a rigorous screening and quality evaluation, 18 studies were selected for meta-analysis using Review Manager 5.4. Results: Out of 18 studies involving 980 sepsis patients, the meta-analysis revealed the following for the levosimendan group compared to dobutamine: (1) A significant reduction in mortality rate (OR = 0.63, 95% CI (0.42,0.95), P = .03). (2) Shortened ICU stay (MD = -2.55, 95% CI (-3.12, -1.98), P < .00001). (3) Increased left ventricular ejection fraction (LVEF) (MD = 6.05, 95%CI (5.28, 6.81), P < .00001) and cardiac index (CI) (MD = 0.47, 95%CI (0.35, 0.59), P < .00001). (4) Decreased blood lactate (Lac) (MD = -1.31, 95%CI (-1.73, -0.90), P < .00001) and troponin I (TnI) levels (MD = -0.43, 95%CI (-0.66, -0.21), P = .0002). (5) Reduced incidence of adverse events (OR = 0.43, 95% CI (0.23,0.81), P = .008). Conclusions: Compared to dobutamine, levosimendan substantially enhances cardiac function in sepsis patients, leading to improved outcomes and fewer adverse events.

Kaempferol promotes non-small cell lung cancer cell autophagy via restricting Met pathway.

BACKGROUND: Kaempferol is extracted from Hedyotis diffusa, exerting an obvious anti-cancer effect. Here in the present study, we explored the anti-cancer effects and mechanism of kaempferol in non-small cell lung cancer cell (NSCLC). PURPOSE: Our objective is to figure out the molecular mechanism by which kaempferol promotes autophagy in NSCLC cells. STUDY DESIGN: A549 and H1299 NSCLC cell lines were used for in vitro experiments. And BALB/c nude mice of NSCLC were used to perform in vivo experiments. METHODS: For in vitro experiments, CCK-8 and EdU assay was used to observe the effect of kaempferol on NSCLC cell proliferation. Confocal microscopy of mCherry-EGFR-LC3 assay and electron microscopy assay were used to detect NSCLC cell autophagy. Protein expression was determined using Western blot, and mRNA expression was determined using qRT-PCR. Flow cytometry was performed to detect the cell apoptosis. For in vivo experiments, a subcutaneously implanted tumor model in BALB/C nude mice was performed using human NSCLC cell line A549-Luc. The kaempferol effect on NSCLC mice model was detected by measuring the tumor weight and bioluminescence intensity. Immunohistochemistry was done to measure the key protein expression from mice tumor tissues. RESULTS: Our results confirmed that kaempferol inhibited NSCLC cell proliferation significantly. And it promoted NSCLC cell autophagy, leading to NSCLC cell death. Interestingly, Met-was greatly inhibited at both protein and mRNA levels. Meanwhile, PI3K/AKT/mTOR signaling pathway was inhibited accordingly. Furthermore, overexpressing Met-reversed the effect of kaempferol on NSCLC cell viability and cell autophagy with significance. Finally, the above effect and pathway were validated using the xenograft model. CONCLUSION: Kaempferol may exert its anti-NSCLC effect by promoting NSCLC cell autophagy. Mechanistically, Met-and its downstream PI3K/AKT/mTOR signaling pathway were involved in the process, which provides a novel mechanism how kaempferol functions in inhibiting NSCLC.

The application of arsenic trioxide in cancer: An umbrella review of meta-analyses based on randomized controlled trials.

ETHNOPHARMACOLOGICAL RELEVANCE: Processed from natural minerals, arsenic trioxide (ATO) as an ancient Chinese medicine has been used to treat diseases for over 2000 years. And it was applied to treat acute promyelocytic leukemia (APL) since the 1970s in China. Summarizing the clinical evidence of ATO in cancer is conducive to further understanding, development, and promotion of its pharmacological research. AIM OF THE STUDY: It is the first time to comprehensively assess and summarize the evidence of ATO in cancer treatment via umbrella review. MATERIALS AND METHODS: 8 databases in English or Chinese from their inception to February 21, 2023 were searched by two reviewers separately and suitable meta-analyses (MAs) were included in this umbrella review. Their methodological quality and risk of bias were evaluated and data of outcomes was extracted and pooled again. The evidence certainty of pooled results was classified. RESULTS: 17 MAs with 27 outcomes and seven comparisons in three cancers were included in this umbrella review. However, their methodological quality was unsatisfactory with 6 MAs as low quality and 12 MAs as critically low quality. Their shortcomings were mainly focused on protocol, literature selecting, bias risk, small sample study bias, and conflicts of interest or funding. And they were all assessed as high risk in bias. It was suggested that ATO had an advantage in enhancing complete remission rate, event-free survival, and recurrence free survival and decreasing recurrence rate, cutaneous toxicity, hyper leukocyte syndrome, tretinoin syndrome, edema and hepatotoxicity in different comparisons of APL with low or moderate certainty. Besides, compared with transcatheter arterial chemoembolization (TACE) alone, ATO plus TACE also could improve objective response rate, disease control rate, survival rate (0.5, 1, 2, and 3-year) and life quality and reduce the level of alpha fetoprotein in primarily hepatocellular carcinoma with low or moderate certainty. However, no significant results were found in MM. Finally, key findings were as followed. ATO has potential broad-spectrum anticancer effects but the clinical transformation is rarely achieved. Route of administration may affect the antitumor effects of ATO. ATO can act synergistically in combination with a variety of antitumor therapies. The safety and drug resistance of ATO should be paid more attention to. CONCLUSIONS: ATO may be a promising drug in anticancer treatment although earlier RCTs have dragged down the level of evidence. However, high-quality clinical trials are expected to explore its broad-spectrum anticancer effects, wide application, appropriate route of administration, and compound dosage form.

Fuzheng Kang-Ai inhibits NSCLC cell proliferation via regulating hsa_circ_0048091/hsa-miR-378g/ARRDC3 pathway.

BACKGROUND: Current treatments for lung cancer have their own deficiencies, such as severe adverse effect. Therefore, more safe and effective drugs are needed. PURPOSE: Fuzheng Kang-Ai (FZKA for short) has been applied as an adjuvant treatment in advanced Non-Small Cell Lung Cancer (NSCLC) patients for decades in China, showing a definitive effect with minimal toxicities. However, the underlying mechanism is yet to be identified. STUDY DESIGN: Both in vitro and in vivo experiments were performed in this study to identify the exact mechanism by which FZKA inhibits NSCLC cell proliferation. METHODS: MTT and CCK-8 assays were used to detect cell viability. Xenograft model was performed for in vivo experiments. CircRNA and miRNA sequencing were used to find the differentially expressed circRNAs and miRNAs, respectively. qRT-PCR was performed to check the expression levels of circRNA, miRNA and mRNA. BaseScope was carried out to observe the expression of circRNA in situ. Actinomycin D and RNase R experiments were done to show the stability of circRNA. Nuclear-cytoplasmic fractionation and FISH were used to identify the localization of circRNA and miRNA. Pull-down, RIP, and luciferase activity assays were performed to show the biding ability of circRNA, miRNA and target proteins. Flow cytometry was done to observe cell apoptosis. Western blot and IHC were done to detect the protein expression. TCGA database was used to analyze the survival rate. RESULTS: FZKA inhibits NSCLC cell proliferation both in vitro and in vivo. Hsa_circ_0048091 and hsa-miR-378g were the most differentially expressed circRNA and miRNA, respectively, after FZKA treatment. Silencing hsa_circ_0048091 and overexpressing hsa-miR-378g promoted cell proliferation and reversed the inhibition effect of FZKA on NSCLC, respectively. Hsa-miR-378g was sponged by hsa_circ_0048091, and the overexpression of miR-378g reversed the inhibition effect of hsa_ circ_0048091 on NSCLC. ARRDC3, as a target of hsa-miR-378g, was increased by FZKA treatment. Silencing ARRDC3 reversed both the inhibition effect of FZKA and miR-378g inhibitor on NSCLC. CONCLUSION: This study, for the first time, has established the function of hsa_circ_0048091, hsa- miR-378g, and ARRDC3 in lung cancer. It also shows that FZKA inhibits NSCLC cell proliferation through hsa_circ_0048091/hsa-miR-378g/ARRDC3 pathway, uncovering a novel mechanism by which FZKA controls human NSCLC cell growth.

Hovenianin A Alleviates Hepatic Fibrosis by Inhibiting the PI3K/AKT Pathway in TGF-ß1-Induced HSCs Based on Network Pharmacology and Transcriptomic Analysis.

Hepatic fibrosis is a global health problem, which currently has no FDA approved antifibrotic therapy yet. This study aimed to explore the mechanism of Hovenia genus in the treatment of hepatic fibrosis by an integrative strategy combining network pharmacology analysis, molecular docking, transcriptomics and experimental validation. The traditional Chinese medicine systems pharmacology (TCMSP) database and literatures were used to collect the components of Hovenia genus. Public databases including GeneCards, TTD, PharmGkb were used to acquire the putative targets. The GO and KEGG analysis were applied to explore the underlying mechanisms. Furthermore, The TGF-ß1 induced hepatic stellate cells (HSCs) model were performed to evaluate the anti-hepatic fibrosis activity of Hovenia genus. The RT-qPCR, Western blotting and flow cytometry experiments were used to validate the anti-hepatic fibrosis mechanisms of Hovenianin A. The KEGG analysis of network pharmacology and transcriptomics revealed that the core targets mainly enriched in PI3K-Akt signaling pathways. The cell screening results indicated flavonoids were the main active ingredients of Hovenia. Hovenianin A, a bioactive bisflavonol, was validated to promote the apoptosis of HSCs by inhibiting PI3K-Akt pathway. Molecular docking further corroborated the binding sites between Hovenianin A and AKT1. In summary, Hovenia may have therapeutic effects on liver fibrosis by modulating the PI3K-Akt apoptosis pathway. Our findings may facilitate the development of Hovenia genus, which could help to treat liver fibrosis in the future.

GPX4 Plays a Crucial Role in Fuzheng Kang'ai Decoction-Induced Non-Small Cell Lung Cancer Cell Ferroptosis.

Background: Fuzheng Kang'ai decoction (FZKA) has been widely used to treat Non-Small Cell Lung Cancer (NSCLC) patients in China for decades, showing definitively curative effects in clinic. Recently, we found that FZKA could induce NSCLC cell ferroptosis, another type of programmed cell death (PCD), which is totally different from cell apoptosis. Therefore, in the present study, we aim to discover the exact mechanism by which FZKA induces NSCLC cell ferroptosis, which is rarely studied in Traditional Chinese Medicine (TCM). Methods: Cell proliferation assay were performed to detect the cell viability. Cell ferroptosis triggered by FZKA was observed by performing lipid peroxidation assay, Fe2+ Ions assay, and mitochondrial ultrastructure by transmission electron microscopy. Ferroptosis inhibitors including liproxstatin-1 and UAMC 3203 were used to block ferroptosis. The ratio of GSH/GSSG was done to measure the alteration of oxidative stress. Western blot and qRT-PCR were carried out to detect the expression of solute carrier family 7 member 11 (SLC7A11), solute carrier family 3 member 2 (SLC3A2) and glutathione peroxidase 4 (GPX4) at protein and mRNA levels, respectively. Lentivirus transfection was performed to overexpress GPX4 stably. Animal model was done to verify the effect of FZKA-induced ferroptosis in NSCLC in vivo and immunohistochemistry was done to detect the expression of SLC7A11, SLC3A2 and GPX4 at protein level. Results: First of all, in vitro experiments confirmed the inhibition effect of FZKA on NSCLC cell growth. We then, for the first time, found that FZKA induced NSCLC cell ferroptosis by increasing lipid peroxidation and cellular Fe2+ Ions. Moreover, characteristic morphological changes of NSCLC cell ferroptosis was observed under transmission electron microscopy. Mechanistically, GPX4, as a key inhibitor of lipid peroxidation, was greatly suppressed by FZKA treatment both at protein and mRNA levels. Furthermore, system xc- (SLC7A11 and SLC3A2) were found to be suppressed and a decreased GSH/GSSG ratio was observed at the same time when treated with FZKA. Notably, overexpressing GPX4 reversed the effect of FZKA-induced NSCLC cell ferroptosis significantly. Finally, the above effect was validated using animal model in vivo. Conclusion: Our findings conclude that GPX4 plays a crucial role in FZKA-induced NSCLC cell ferroptosis, providing a novel molecular mechanism by which FZKA treats NSCLC.

Efficacy and safety of Brucea javanica oil emulsion injection as adjuvant therapy for cancer: An overview of systematic reviews and meta-analyses.

BACKGROUND: In China, Brucea javanica oil emulsion injection (BJOEI) has been used as adjuvant therapy to treat cancer for many years. Many systematic reviews (SRs) or meta-analyses (MAs) were published to evaluate its efficacy and safety. Nevertheless, uneven quality made it difficult to reach a consensus and there has been no specific review to integrate the evidence of BJOEI for cancer at present. Therefore, a comprehensive evidence map is needed to guide clinicians. PURPOSE: We, for the first time, conducted an overview to assess the SRs/MAs of BJOEI, and provided a comprehensive evidence map to guide clinicians. Besides, this study provided a promising direction for future research to promote the generation of advanced evidence. STUDY DESIGN: An overview of SRs or MAs. METHODS: The pre-defined search strategies were applied to 8 databases. Suitable SRs/MAs were included according to the inclusion and exclusion criteria. Methodological quality, reporting quality, and risk of bias were assessed. An evidence map was conducted to show the situation of clinical evidence. RESULTS: 27 SRs/MAs in 7 cancer types were included in this overview. The main problems of SRs/MAs were concentrated on the following aspects: without registration or protocol, lacking gray literature retrieval and a list of excluded studies, incomplete description in the literature retrieval strategy or the methods of merging results, the bias of each synthetic result, less exploration in heterogeneity or publication bias, deficiencies in assessing evidence quality and less description in conflict, funding or access to relevant information. Based on the rules of GRADE, the evidence quality of 154 items in 27 SRs/MAs was defined as moderate quality (103 items), low-quality (44 items), and very low-quality (7 items). Especially, risk of bias (154 items), imprecision (27 items), inconsistency (20 items), and publication bias (9 items) were the main downgrading factors. CONCLUSION: BJOEI may be a promising adjuvant therapy for treating cancer, especially in the digestive system. However, high-quality SRs/MAs are expected to be carried out to improve the reliability of the above conclusion in the future.

Efficacy and Safety of Huaier Granule as an Adjuvant Therapy for Cancer: An Overview of Systematic Reviews and Meta-Analyses.

INTRODUCTION: In China, Huaier granule (HG) is widely applied to tumor adjuvant therapy. However, systematic reviews (SRs) or meta-analyses (MAs) published continuously failed to reach a consensus, without convincing evidence. An overview should be conducted to summarize the evidence-based progress and try to provide some value references for relative research and clinical practice in the future. METHODS: From inception to October 2021, 8 databases in English and Chinese were searched. SRs/MAs meeting the inclusion and exclusion criteria were included. Relevant criteria were used to evaluate SRs/MAs including methodological quality, reporting quality, risk of bias, and evidence quality of effect and safety. RESULTS: The short-term effect, long-term effect, and safety in 6 included SRs/MAs were assessed in this overview according to quantitative synthesis. Results assessed by AMSTAR-2, PRISMA, and ROBIS were generally unsatisfactory with the main problems on registration or protocol, a search of grey literature, a list of excluded studies, bias of each synthetic result, and inadequate report of search strategy and synthesis methods. Additionally, 28 items were assessed as moderate quality while 12 items were low-quality and 6 items were very low-quality in GRADE. Risk of bias was the main downgrading factor. CONCLUSION: HG may be a promising adjuvant therapy for cancer. However, high-quality SRs/MAs and RCTs should be conducted to provide sufficient evidence so as to draw a definitive conclusion.

Positive Role of Chinese Herbal Medicine in Cancer Immune Regulation.

Complementary and alternative medicine (CAM) plays a critical role in treating cancer patients. Traditional Chinese Medicine (TCM) is the main component of CAM. TCM, especially Chinese Herbal Medicine (CHM), has been increasingly used in China, some other Asian countries and European countries. It has been proven to enhance the efficacy of chemotherapy, radiotherapy, targeted-therapy, and immunotherapy. It lessens the damage caused by these therapies. CHM functions on cancer by inhibiting tumor progression and improving an organism's immune system. Increasing evidence has shown that many CHM exert favorable effects on the immune regulation. We will summarize the role of CHM on patient's immune system when treating cancer patients. Our evidence reveals that single herbs, including their extracts, compound formulations, and preparations, will provide current advances on CHM study, especially from the perspective of immune regulation and novel insights for CHM application in clinic. The main herbs used to treat cancer patients are health-strengthening (Fu-Zheng) herbs and pathogen eliminating (Qu-Xie) herbs. The key mechanism is regulating the immune system of cancer patients. Firstly, health-strengthening herbs are mainly functioned as immune regulatory effectors on cancer. Secondly, some of the compound formulations mainly strengthen the health of patients by regulating the immune system of cancer patients. Lastly, some Chinese medicine preparations are widely used to treat cancer for their properties of spiriting vital energy and anti-cancer effects, mainly by improving immunity. CHM plays a positive role in regulating patients' immune system, which helps cancer patients to fight against cancer itself and finally improves patients' life quality.

Effectiveness and safety of traditional Chinese medical therapy for cancer-related fatigue: a systematic review and Meta-analysis of randomized controlled trials.

OBJECTIVE: To assess the effectiveness and safety of traditional Chinese medical therapy for cancer-related fatigue. METHODS: We systematically searched eight electronic databases up to June 2017 for randomized clinical trials of traditional Chinese medical therapy for cancer-related fatigue. Two authors independently extracted data and assessed the risk bias of the included trials using the Cochrane Handbook. Data were analyzed by RevMan 5.2 software. RESULTS: A total of 23 trials involving 1832 participants identified with cancer-related fatigue were included. Twenty trials reported a beneficial effect of traditional Chinese medical therapy on cancer-related fatigue. On pooling the data from Chinese herbal medicine therapy and acupuncture or moxibustion therapy, respectively, significant differences were found between experimental groups and control groups. Fatigue improvement rates showed significant differences between traditional Chinese medical therapy and control groups [odds ratio (OR), 7.62; 95% confidence interval (CI), 3.75-15.49; P < 0.000 01; and OR, 3.78; 95% CI, 2.29-6.23; P < 0.000 01). Fatigue change scores also showed significant differences between the two groups (mean difference, -0.91; 95% CI, -0.16 to -0.65; P < 0.000 01). Eleven trials demonstrated that traditional Chinese medical therapy improved the quality of life of cancer patients. No severe adverse effects occurred in traditional Chinese medical therapy groups. CONCLUSION: Meta-analysis showed that Chinese medical therapy seems to be effective and safe in the treatment of cancer-related fatigue.

Effect of Jian-Pi-Zhi-Dong Decoction on the Amino Acid Neurotransmitters in a Rat Model of Tourette Syndrome and Comorbid Anxiety Disorder.

Amino acid neurotransmitters have been shown to correlate with Tourette syndrome (TS) and its comorbidities. In this study, we investigated the effects of Jian-Pi-Zhi-Dong Decoction (JPZDD), a formula containing 10 different Chinese medical herbs, on amino acid neurotransmitters in rats. We established a rat model of Tourette syndrome and comorbid anxiety with an iminodipropionitrile injection plus uncertain empty water bottle stimulation for 3 weeks. Then the rats were randomly divided into four groups: control group and model group were gavaged with saline, while the remaining two treatment groups were gavaged with fluoxetine hydrochloride or JPZDD for four consecutive weeks. We recorded the behaviors of the rats with TS and comorbid anxiety by stereotypy recording, open field test, and elevated plus maze. We observed mitochondrial changes with transmission electron microscopy. We measured the content of glutamate (GLU) and γ-aminobutyric acid (GABA) both in the serum and striatum and the expression of their receptors by Western blot and real-time polymerase chain reaction. The study revealed that JPZDD was effective in alleviating the behavioral symptoms of both tic and anxiety in the rat model groups. These results might be associated with the increase in GABA levels and decrease in GLU levels in the serum, as well as an increase in striatal GABA level by the activation of GABA receptors Type A (GABAAR). JPZDD treatment also reversed the mitochondrial dysfunction both in the striatum and cortex in affected animals.

Fuzheng Kang-Ai decoction enhances the effect of Gefitinib-induced cell apoptosis in lung cancer through mitochondrial pathway.

BACKGROUND: Our previous clinical study has shown that Chinese herbal medicine (CHM) Fuzheng Kang-Ai (FZKA) decoction is effective in treating advanced lung cancer patients through prolonging the drug resistance to Gefitinib (GFTN). Our basic study found that FZKA decoction could enhance the inhibition effect of GFTN in lung cancer by inactivating PI3K/Akt pathway. Moreover, our recent work showed that FZKA induced lung cancer cell apoptosis via STAT3/Bcl-2/Caspase-3 pathway. Thus in this study, we aim to elucidate how FZKA enhances the effect of GFTN in lung cancer from the perspective of cell apoptosis. METHODS: Cell proliferation and colony formation assay were performed to detect the cell growth inhibition. Flow cytometry and TUNEL assay were carried out to test the cell apoptosis. Mitochondrial membrane potential (MMP) assay was done to measure the alteration of MMP. Caspase-3/-9 activity assay was used to test the activity of caspase-3/-9. Western blot and qRT-PCR were done to detect the expression of STAT3 and Bcl-2 family as well as Caspase-3/-9 and Cyt-C at protein and mRNA levels, respectively. Transient transfection was performed to silence STAT3 using siSTAT3. Animal model was done to validate the molecular mechanisms in vivo and immunohistochemistry was done to detect the expression of Bax and Caspase-3. RESULTS: Firstly, our results showed that FZKA enhanced the inhibition effect of GFTN in lung cancer both in vitro and in vivo. Secondly, cell apoptosis was enhanced when treating lung cancer cells with both FZKA and GFTN, a process involving the mitochondria and the Bcl-2 family. And Bcl-2 family was involved in this process. Interestingly, STAT3 plays a critical role on mediating the above process. Last but not the least, the enhanced effect of cell apoptosis induction of GFTN by FZKA was validated in animal model. CONCLUSION: Our findings conclude that Fuzheng Kang-Ai decoction enhances the effect of GFTN-induced cell apoptosis in lung cancer through the mitochondrial pathway, providing a novel molecular mechanism by which FZKA sensitizes to GFTN by delaying drug resistance in treating lung cancer patients.

Thalamic Deep Brain Stimulation for Essential Tremor: Relation of the Dentatorubrothalamic Tract with Stimulation Parameters.

BACKGROUND: In deep brain stimulation (DBS) for essential tremor, the primary target ventrointermedius (VIM) nucleus cannot be clearly visualized with structural imaging. As such, there has been much interest in the dentatorubrothalamic tract (DRTT) for target localization, but evidence for the DRTT as a putative stimulation target in tremor suppression is lacking. We evaluated proximity of the DRTT in relation to DBS stimulation parameters. METHODS: This is a retrospective analysis of 26 consecutive patients who underwent DBS with microelectrode recordings (46 leads). Fiber tracking was performed with a published deterministic technique. Clinically optimized stimulation parameters were obtained in all patients at the time of most recent follow-up (6.2 months). Volume of tissue activated (VTA) around contacts was calculated from a published model. RESULTS: Tremor severity was reduced in all treated hemispheres, with 70% improvement in the treated hand score of the Clinical Rating Scale for Tremor. At the level of the active contact (2.9 ± 2.0 mm superior to the commissural plane), the center of the DRTT was lateral to the contacts (5.1 ± 2.1 mm). The nearest fibers of the DRTT were 2.4 ± 1.7 mm from the contacts, whereas the radius of the VTA was 2.9 ± 0.7 mm. The VTA overlapped with the DRTT in 77% of active contacts. The distance from active contact to the DRTT was positively correlated with stimulation voltage requirements (Kendall τ = 0.33, P = 0.006), whereas distance to the atlas-based VIM coordinates was not. CONCLUSIONS: Active contacts in proximity to the DRTT had lower voltage requirements. Data from a large cohort provide support for the DRTT as an effective stimulation target for tremor control.

Focused Ultrasound Thalamotomy for Essential Tremor in the Setting of a Ventricular Shunt: Technical Report.

BACKGROUND: A recent randomized controlled trial of magnetic resonance imaging (MRI)-guided focused ultrasound (FUS) for essential tremor (ET) demonstrated safety and efficacy. Patients with ventricular shunts may be good candidates for FUS to minimize hardware-associated infections. OBJECTIVE: To demonstrate feasibility of FUS in this subset of patients. METHODS: A 74-yr-old male with medically refractory ET, and a right-sided ventricular shunt for normal pressure hydrocephalus, underwent FUS to the right ventro-intermedius (VIM) nucleus. The VIM nucleus was directly targeted using deterministic tractography. Clinical outcomes were measured using the Clinical Rating Scale for Tremor. RESULTS: Shunt components required 6% of the total ultrasound transducer elements to be shut off. Eight therapeutic sonications were delivered (maximum temperature, 64°), leading to a 90% improvement in hand tremor and a 100% improvement in functional disability at the 3-mo follow-up. No complications were noted. CONCLUSION: This is the first case of FUS thalamotomy in a patient with a shunt. Direct VIM targeting and achievement of therapeutic temperatures with acoustic energy is feasible in this subset of patients.

Decoction of Chinese Herbal Medicine Fuzheng Kang-Ai Induces Lung Cancer Cell Apoptosis via STAT3/Bcl-2/Caspase-3 Pathway.

Decoction of Chinese herbal medicine (CHM) Fuzheng Kang-Ai (FZKA for short) has been applied as adjuvant treatment strategy in advanced lung cancer patients for decades. We previously showed that FZKA decoction inhibited proliferation of non-small cell lung cancer (NSCLC) cells through activation of AMP-activated protein kinase alpha (AMPKα) signaling pathway, followed by inducing insulin-like growth factor (IGF) binding protein 1 (IGFBP1) and forkhead homeobox type O3a (FOXO3a) proteins, and enhanced the inhibition effect of gefitinib in lung cancer cell growth via inactivating PI3-K/Akt-mediated suppressing of cell surface-associated mucin-1 (MUC1) expression. In this study, we investigated the molecular mechanism by which FZKA decoction affected cell apoptosis in lung cancer cells. Our results show that FZKA induced apoptosis in lung cancer cells. Mechanistically, FZKA activated the caspase-3, PARP, and caspase-9 activities. Both antiapoptotic and proapoptotic proteins from Bcl-2 family were deregulated by FZKA exposure in lung cancer cells. In addition, FZKA reduced protein expressions of signal transducer and activator of transcription 3 (STAT3) and Jun activation domain-binding protein 1 (Jab1), while it concomitantly increased p21 protein. Moreover, the inhibitor of caspase-3 resisted the effect of FZKA on induction of apoptosis. Finally, exogenous overexpression of STAT3 overcame FZKA-inhibited protein expressions of Bcl-2 and myeloid cell leukemia-1 (Mcl-1) as well as Bax and blocked FZKA-induced activities of caspase-3 and caspase-9. Our results show that FZKA decoction promotes lung cancer cell apoptosis through STAT3/Bcl-2/caspase-3 signaling pathways. This study unveils potential novel molecular mechanism by which FZKA controls growth of human lung cancer cells.

Application of Traditional Chinese Medicines as Personalized Therapy in Human Cancers.

Although lots of great achievements have been gained in the battle against cancer during the past decades, cancer is still the leading cause of death in the world including in developing countries such as China. Traditional Chinese medicine (TCM) is popular in Chinese and East Asian societies as well as some other Western countries and plays an active role in the modern healthcare system including patients with cancer, which may act as a potential effective strategy in treating human cancers. In this review, we aimed to introduce the mechanisms of TCM compound, as an option of individualized therapy, in treating cancer patients from the perspective of both Chinese and Western medicine. In the view of traditional Chinese medicine theory, individualized treatment for human cancers based on syndrome type benefits the cancer patients with personalized conditions. Balancing Qi, Xue, Yin and Yang, eliminating phlegm and removing dampness is how TCM compound functions on cancer patients. While in the view of Western medicine, inhibiting cancer cell growth and metastasis as well as improving immune status is how herbal compounds act on cancer patients. We also summarized the applications of TCM compound in human cancers, which will shed light on the clinical application of TCM compound on patients with cancer. TCM compound could be used as a complementary and alternative medicine (CAM) in human cancers. It could be applied in cancer patients with cancer-related fatigue (CRF). In addition, it is a good method for alleviating the side effects of both radiotherapy and chemotherapy. Therefore, TCM compound plays a critical role in treating patients with cancer, which has a promising strategy in the field of cancer management.

Traditional Chinese medicine, Fuzheng Kang­Ai decoction, inhibits metastasis of lung cancer cells through the STAT3/MMP9 pathway.

Lung cancer is a leading cause of cancer­associated mortality worldwide, including in developing countries such as China. Traditional Chinese medicine may provide a novel insight for the treatment of patients with lung cancer. The present study aimed to uncover the mechanism by which the Chinese herbal medicine, Fuzheng Kang­Ai (FZKA), functions on lung cancer cell metastasis. The results demonstrated that treatment with FZKA markedly inhibited cell viability, migration and invasion of lung cancer cells, as determined by cell viability and Transwell assays. Notably, the activity and expression of matrix metalloproteinase 9 (MMP9) was significantly inhibited by FZKA treatment on lung cancer cells, as determined by an MMP9 activity assay and western blot analysis. Furthermore, FZKA markedly inhibited epithelial­mesenchymal transition (EMT) of lung cancer cells by inhibiting the expression of the mesenchymal markers N­cadherin and vimentin. In addition, activation of the oncoprotein signal transducer and activator of transcription 3 (STAT3) was suppressed following treatment with FZKA. Conversely, overexpression of STAT3 was able to rescue MMP9 activity following FZKA treatment. The present study indicated that FZKA may inhibit lung cancer metastasis via the STAT3/MMP9 pathway and EMT, suggesting that FZKA may serve as a novel promising therapeutic strategy for the treatment of patients with late stage lung cancer.

Chinese herbal medicine Fuzheng Kang-Ai decoction sensitized the effect of gefitinib on inhibition of human lung cancer cells through inactivating PI3-K/Akt -mediated suppressing MUC1 expression.

ETHNOPHARMACOLOGICAL RELEVANCE: Chinese herbal medicine (CHM) Fuzheng Kang-Ai (FZKA for short) decoction has been used as adjuvant treatment strategies in lung cancer patients for decades. However, the molecular mechanism underlying the therapeutic potential especially in sensitizing the effect of EGFR-TKI gefitinib has not been well elucidated. MATERIALS AND METHODS: Cell viability was detected by MTT assay. Cell cycle distribution was detected by flow cytometry. Western blot were used to examine phosphorylation and protein levels of Akt, p65, p50 and MUC1. The mRNA level of MUC1 was measured by qRT-PCR. Transient transfection experiments were used to overexpression of Akt, p65 and MUC1. Tumor xenograft and bioluminescent imaging experiments were carried out to confirm the in vitro findings. RESULTS: Cell viability was inhibited by FZKA treatment and showed more significant when treated with FZKA and gefitinib in combine in lung cancer cells. FZKA induced the cell arrest at G0/G1 phase. Mechanistically, we showed that the phosphorylation of Akt, protein expressions of p65 and MUC1 were suppressed by FZKA and even more responses were observed in the FZKA and gefitinib combining. Overexpressed Akt overcame the effect of FZKA on p65 protein, and exogenously expressed p65 resisted the inhibitory effect of MUC1 protein expression by FZKA. On the contrary, while overexpressed MUC1 had no effect on p65 expression, it feedback increased phosphorylation of Akt, and more importantly, reversed the cell growth inhibition affected by FZKA. In line with the above, our results confirmed the synergistic effects of FZKA and gefitinib combination on tumor growth, the phosphorylation of Akt, and protein expression of p65 and MUC1 in vivo. CONCLUSION: This study shows that FZKA decoction inhibits the growth of NSCLC cells through Akt-mediated inhibition of p65, followed by reducing the expression of MUC1. More importantly, there is a synergistic effect of FZKA decoction and gefitinib combination with greater suppression. The positive feedback regulatory loop of MUC1 to Akt signaling pathway further added the important role of MUC1 in mediating the overall responses of FZKA decoction in this process. The in vitro and in vivo study provides an additional and a novel mechanism by which the FZKA decoction enhances the growth inhibition of gefitinib in gefitinib-resistant NSCLC cells.
