Efficient removal of U(VI) from aqueous solution by CNN/UiO-66 under simulated sunlight irradiation: the synergy of adsorption and photocatalysis.

The reduction of soluble U(VI) to insoluble and less toxic U(IV) by photocatalysis is an effective method to control uranium contamination. The graphitic carbon nitride nanosheet (CNN)/UiO-66 composites (CNNU) were prepared by thermal polymerization and solvothermal methods for the removal of U(VI). The morphology, crystal structure and optical properties of composites were analyzed by SEM, XRD, BET, UV-DRS, PL and EIS. The results showed the introduction of UiO-66 increased the specific surface of CNN from 9.07 m2/g to 46.24 m2/g, and effectively suppressed the recombination of photogenerated electrons and holes and improved the photocatalytic activity. The U(VI) removal capacity by adsorption and photocatalysis of CNNU was reached 779.47 mg/g, which significantly higher than that of adsorption (478.38 mg/g). The adsorption process was found to conform to the pseudo-second-order kinetic model and the Langmuir isothermal model. Meanwhile, U(VI) adsorbed on the CNNU was reduced to U(IV) via e- and ·O2- generated in the photocatalytic process. Therefore, this outstanding performance of CNNU in U(VI) removal is attributed to the synergistic effect of adsorption and photocatalytic reduction.

Effect of manual lymphatic drainage combined with targeted rehabilitation therapies on the recovery of upper limb function in patients with modified radical mastectomy: A randomized controlled trial.

Objectives: This study aimed to evaluate the effect of manual lymphatic drainage (MLD) combined with targeted rehabilitation therapies on the recovery of upper limb function in patients with breast cancer after modified radical mastectomy. Patients and methods: In the randomized controlled study conducted between October 2019 and June 2020, 104 eligible breast cancer patients who underwent modified radical mastectomy were randomly divided into two groups. The routine functional exercise group (Group RF) received regular functional exercise guidance. In addition, the MLD combined with targeted rehabilitation therapies group (Group MLDT) received MLD, targeted rehabilitation therapies, and regular functional exercise guidance. The primary endpoints were shoulder range of motion, arm circumference and the incidence of axillary web syndrome (AWS). The secondary endpoints included the duration of axillary drainage, the duration of chest wall drainage, and complications. Results: One hundred participants (mean age: 51.9±8.0 years; range, 28 to 72 years) were included in the final analysis as four patients could not complete the study. A significant improvement in shoulder range of motion was observed in Group MLDT compared to Group RF (p<0.05). Additionally, in Group MLDT, the duration of chest wall drainage was reduced (p=0.037). The frequency of AWS in Group RF was twice that in Group MLDT (p=0.061), but there was no significant difference in arm circumference (p>0.05) or the duration of axillary drainage (p=0.519). Regarding complications, there was one case of necrosis in the MLDT group and four cases in the RF group, including wound infection and seroma. Conclusion: Manual lymphatic drainage combined with targeted rehabilitation therapies is an effective strategy to improve shoulder function, shorten the duration of chest wall drainage, reduce complications, and partly lower the incidence of AWS.

Comparative efficacy of mind-body exercise for depression in breast cancer survivors: A systematic review and network meta-analysis.

BACKGROUND: As pharmacotherapy often leads to adverse reactions, mind-body exercise (MBE) treatments have become a more popular option for treating depression in people living with breast cancer (BC). However, the most effective type of MBE treatment for this population remains unclear. AIMS: The aim of this systematic review and network meta-analysis (NMA) was to compare the efficacy of the different MBE modes for depression in people with BC. METHODS: A systematic search for randomized controlled trials (RCTs) from inception to March 25, 2023, was conducted in the following database: EMBASE, PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine, OpenGrey, and ClinicalTrials.gov. A traditional meta-analysis was conducted using the random-effects model to directly assess the effectiveness of various MBE interventions. Stata 16.0 software was used for performing the NMA. RESULTS: The NMA was performed in 32 eligible RCTs including 2361 participants. The efficacy of MBE treatments on depression was ranked as the following: Liuzijue (surface under the cumulative ranking curve [SUCRA] = 95.4%) > Tai chi (SUCRA = 76.9%) > yoga (SUCRA = 55.0%) > Baduanjin (SUCRA = 53.9%) > Pilates (SUCRA = 38.6%) > dance (SUCRA = 30.2%) > Qigong (SUCRA = 28.1%) > control (SUCRA = 21.9%). LINKING EVIDENCE TO ACTION: Our research showed that Liuzijue and Tai chi might be the most significantly effective MBE intervention for mitigating depression among BC survivors. Healthcare professionals could consider recommending Liuzijue and Tai Chi as a complementary therapy for BC survivors who experience depression.

Nano Ultrasound Contrast Agent for Synergistic Chemo-photothermal Therapy and Enhanced Immunotherapy Against Liver Cancer and Metastasis.

Advanced liver cancer is the most fatal malignant cancer, and the clinical outcomes of treatment are not very satisfactory due to the complexity and heterogeneity of the tumor. Combination therapy can efficiently enhance tumor treatment by stimulating multiple pathways and regulating the tumor immune microenvironment. Nanodrug delivery systems have become attractive candidates for combined strategies for liver cancer treatment. This study reports a nano ultrasound contrast agent (arsenic trioxide (ATO)/PFH NPs@Au-cRGD) to integrate diagnosis and treatment for efficient ultrasound imaging and liver cancer therapy. This nanodrug delivery system promotes tumor-associated antigens release through ATO-induced ferroptosis and photothermal-induced immunogenic cell death, enhancing the synergistic effects of ATO and photothermal therapy in human Huh7 and mouse Hepa1-6 cells. This drug delivery system successfully activates the antitumor immune response and promotes macrophage M1 polarization in tumor microenvironment with low side effects in subcutaneous and orthotopic liver cancer. Furthermore, tumor metastasis is inhibited and long-term immunological memory is also established in orthotopic liver cancer when the nanodrug delivery system is combined with anti-programmed death-ligand 1 (PD-L1) immunotherapy. This safe nanodrug delivery system can enhance antitumor therapy, inhibit lung metastasis, and achieve visual assessment of therapeutic efficacy, providing substantial potential in clinic applications for liver cancer.

Targeting MFAP5 in cancer-associated fibroblasts sensitizes pancreatic cancer to PD-L1-based immunochemotherapy via remodeling the matrix.

Highly desmoplastic and immunosuppressive tumor microenvironment (TME) in pancreatic ductal adenocarcinoma (PDAC) contributes to tumor progression and resistance to current therapies. Clues targeting the notorious stromal environment have offered hope for improving therapeutic response whereas the underlying mechanism remains unclear. Here, we find that prognostic microfibril associated protein 5 (MFAP5) is involved in activation of cancer-associated fibroblasts (CAFs). Inhibition of MFAP5highCAFs shows synergistic effect with gemcitabine-based chemotherapy and PD-L1-based immunotherapy. Mechanistically, MFAP5 deficiency in CAFs downregulates HAS2 and CXCL10 via MFAP5/RCN2/ERK/STAT1 axis, leading to angiogenesis, hyaluronic acid (HA) and collagens deposition reduction, cytotoxic T cells infiltration, and tumor cells apoptosis. Additionally, in vivo blockade of CXCL10 with AMG487 could partially reverse the pro-tumor effect from MFAP5 overexpression in CAFs and synergize with anti-PD-L1 antibody to enhance the immunotherapeutic effect. Therefore, targeting MFAP5highCAFs might be a potential adjuvant therapy to enhance the immunochemotherapy effect in PDAC via remodeling the desmoplastic and immunosuppressive microenvironment.

Six undescribed derivatives of stilbene isolated from Lindera reflexa Hemsl. and their anti-tumor and anti-inflammatory activities.

Six undescribed stilbene derivatives Reflexanbene DH (1-4, 6) and Reflexanbene J (5), as well as one known stilbene 3,5-dimethoxystilbene (7), were isolated from the dried roots of Lindera reflexa Hemsl. Their structures and absolute configurations were elucidated using spectroscopy and electronic circular dichroism (ECD) analysis. In cytotoxic assays, moderately inhibitory activities of Reflexanbene F (3) against MGC80-3 and A549 cell lines were observed, with IC50 values of 15.42 and 5.09 µM, respectively. The IC50 value of Reflexanbene E (2) on A549 cell lines was 19.78 µM. The isolated compounds were also tested for their inhibitory effect against LPS-induced NO and IL-6 production in RAW 264.7 cells. In particular, Reflexanbene J (5) and Reflexanbene H (6) showed significant inhibition of NO production in LPS-stimulated macrophage RAW 264.7 cells at the concentration of 20 µM. Furthermore, the expression of IL-6 protein in the LPS-induced RAW 264.7 cells can also be significantly inhibited by different concentrations (5, 10 and 20 µM, p < 0.05 or p < 0.01) of compounds 1-7.

A network pharmacology-based exploration of the active compounds and potential drug targets of Si-Jun-Zi decoction in the treatment of cutaneous squamous cell carcinoma.

Background: Cutaneous squamous cell carcinoma (cSCC), a kind of skin cancer with high rates of morbidity and mortality, occurs frequently in the clinic. Although early surgical treatment can achieve good results, there is no effective prevention and treatment for the recurrence and metastasis of cSCC. As a useful resource to protect humans from disease, traditional Chinese medicine (TCM) has been adopted by clinicians for thousands of years. Methods: In this study, we collected a Chinese medicine formula and then employed a data mining method to analyze drug combinations of Si-Jun-Zi (SJZ) decoction. Multiple databases were used in this study to predict various ingredients, compounds, and their targets in the decoction. The potential targets of cSCC were also obtained from the database in the same way. In addition, as bioinformatics analysis methods, Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were used in our research as supplementary means to network pharmacology. Finally, we used ultra-performance liquid chromatography (UPLC) fingerprinting to analyze the effective components of the TCM decoction. Results: We detected 559 active compounds from Ginseng, Largehead Atractylodes, India Bread, and Glycyrrhiza Inflata, and selected 136 molecules under specific conditions. The mechanisms of the TCM formula were illustrated by the network pharmacology, such as compounds-herb network, compounds-target network, disease-target network, and target-target interaction network, as well as characteristics of the TCM. Then, GO analysis and KEGG analysis were performed on the compounds in the network using multiple methods of data mining and bioinformatics, and 10 candidate targets were identified. In addition, the UPLC fingerprinting method was used to analyze the components of SJZ decoction. Conclusions: Network pharmacology was performed to investigate the characteristics and mechanism of SJZ decoction, and a bioinformatics method was used to analyze the relationship between the effective compounds of the SJZ TCM decoction and cSCC-related specific targets and pathways, to find a variety of candidate compounds with multi-target activity.

Secondary Metabolites of Osmanthus fragrans: Metabolism and Medicinal Value.

Osmanthus fragrans (scientific name: Osmanthus fragrans (Thunb.) Lour.) is a species of the Osmanthus genus in the family Oleaceae, and it has a long history of cultivation in China. O. fragrans is edible and is well known for conferring a natural fragrance to desserts. This flowering plant has long been cultivated for ornamental purposes. Most contemporary literature related to O. fragrans focuses on its edible value and new species discovery, but the functional use of O. fragrans is often neglected. O, fragrans has many properties that are beneficial to human health, and its roots, stems, leaves, flowers and fruits have medicinal value. These characteristics are recorded in the classics of traditional Chinese medicine. Studies on the metabolites and medicinal value of O. fragrans published in recent years were used in this study to evaluate the medicinal value of O. fragrans. Using keywords such as metabolites and Osmanthus fragrans, a systematic and nonexhaustive search of articles, papers and books related to the medicinal use of Osmanthus fragrans metabolites was conducted. Fifteen metabolites were identified through this literature search and classified into three categories according to their properties and structure: flavonoids, terpenes and phenolic acids. It was found that the pharmacological activities of these secondary metabolites mainly include antioxidant, anticancer, anti-inflammatory and antibacterial activities and that these metabolites can be used to treat many human diseases, such as cancer, skin diseases, cardiovascular diseases, and neurological diseases. Most of the reports that are currently available and concern the secondary metabolites of Osmanthus fragrans have limitations. Some reports introduce only the general classification of compounds in Osmanthus fragrans, and some reports introduce only a single compound. In contrast, the introduction section of this paper includes both the category and the functional value of each compound. While reviewing the data for this study, the authors found that the specific action sites of these compounds and their mechanisms of action in plants are relatively weak, and in the future, additional research should be conducted to investigate this topic further.

Antibiotic-resistant bacteria and antibiotic resistance genes in uranium mine: Distribution and influencing factors.

Both heavy metals and radiation could affect the proliferation and dissemination of emerging antibiotic resistance pollutants. As an environmental medium rich in radioactive metals, the profile of antibiotic resistance in uranium mine remains largely unknown. A uranium mine in Guangdong province, China was selected to investigate the distribution and influencing factors of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) including intracellular ARGs (iARGs), adsorbed-extracellular ARGs (aeARGs), and free extracellular ARGs (feARGs). The result indicated that sulfonamide and tetracycline ARB could be generally detected in mining area with the absolute concentrations of 7.70 × 102-5.18 × 105 colony forming unit/g. The abundances of aeARGs in mine soil were significantly higher than those of iARGs (p < 0.05), highlighting the critical contribution of aeARGs to ARGs spread. The feARGs in mine drainage and its receiving river were abundant (3.38 × 104-1.86 × 107 copies/mL). ARB, aeARGs, and iARGs may correlate with nitrogen species and heavy metals (e.g., U and Mn), and feARGs presented a significant correlation with chemical oxygen demand (p < 0.05). These findings demonstrate the occurrence of ARB and ARGs in uranium mine for the first time, thereby contributing to the assessment and control of the ecological risk of antibiotic resistance in radioactive environments.

[Roles of processing and compatibility in antidepression of Sini Powder:a metabonomics study].

The antidepressant mechanism of Sini Powder was investigated by metabonomics based on UHPLC-Q-TOF-MS, and the roles of processing and compatibility in the antidepression of Sini Powder were discussed in the present study. The chronic unpredictable mild stress(CUMS) model of depression was induced in the model group, the Bupleuri Radix group, the Paeoniae Radix Alba group, the herb-pair group(Bupleuri Radix-Paeoniae Radix Alba), the Sini Powder group, and the vinegar-processed Sini Powder group(Bupleuri Radix and Paeoniae Radix Alba were vinegar-processed). After the establishment of the model, the rats in each group were continuously administered with corresponding drugs(ig) at a dose of 9.6 g·kg~(-1) for eight days [the rats in the model group and the normal group(without model induction) received the same volume of normal saline at the same time]. Following the last administration, the differential metabolites were identified to analyze metabolic pathways based on the rat plasma samples collected from each group. A total of sixteen potential biomarkers were identified. The metabolites with significant changes were involved in many biological metabolic pathways, such as amino acid metabolism, pentose phosphate pathway, glycerol phospholipid metabolism, sphingolipid metabolism, and purine metabolism. After drug intervention, some biomarkers returned to normal levels. Further comparisons of processing and compatibility revealed that the vinegar-processed Sini Powder group had the most total metabolic pathways where differential metabolites were returned to normal. Compared with the individual herbs, the herb-pair significantly improved the recovery of differential metabolites in the pentose phosphate and purine metabolic pathways. Compared with the Sini Powder, the vinegar-processed Sini Powder facilitated the recovery of differential metabolites in the arginine biosynthesis, and pyrimidine and pentose phosphate metabolic pathways. As indicated by the results, Sini Powder may interfere with depression by regulating lipid and nucleotide metabolisms. The processing and compatibility of Chinese herbal medicines can potentiate the intervention on depression by regulating nucleotide, energy, and amino acid metabolisms to a certain extent.

[Potential geographical distribution and changes of Artemisia ordosica in China under future climate change]. / 未来气候变化下黑沙蒿在中国的潜在地理分布及变迁.

Artemisia ordosica is a forerunner species of wind-break and sand-fixation in desert steppe in China, which plays an important role in ecosystem restoration and reconstruction. How-ever, it could influence human health. Based on 89 valid data of current distribution of A. ordosica in China and 19 typical climatic factors, the MaxEnt model was used to simulate the potential distribution of A. ordosica in China under current and two scenarios (RCP 4.5 and RCP 8.5; 2050s and 2070s). The SDM toolbox of ArcGIS software was used to analyze the potential distribution range of A. ordosica and its changes in China. The importance of key climatic factors was evaluated by comprehensive contribution rate, Jackknife method, and response curve of environmental variables. The accuracy of model was tested and evaluated by area under the curve (AUC) of the test subject working characteristic (ROC). The results showed that the MaxEnt model worked well (AUC=0.980). which predicted that A. ordosica was mainly concentrated in and around Mu Us Sandy Land, consistent with the current actual distribution range. The distribution area of A. ordosica of potential high fitness under the future two scenarios decreased by 5.2%-26.8%, which was negatively affected by future climate change. Seasonal variation of temperature, mean precipitation in the coldest season, and mean annual temperature had the greatest impact. The core area of future potential distribution of A. ordosica in China was located in Mu Us Sandy Land, with a tendency for spreading to northeast (Jilin, Heilongjiang, Liaoning and some parts of Hebei).

Serum and Fecal Oxylipins in Patients with Alcohol-Related Liver Disease.

BACKGROUND: Alcohol-related liver disease is one of the most prevalent chronic liver diseases worldwide. Mechanisms involved in the pathogenesis of alcohol-related liver disease are not well understood. Oxylipins play a crucial role in numerous biological processes and pathological conditions. Nevertheless, oxylipins are not well studied in alcohol-related liver disease. AIMS: (1) To characterize the patterns of bioactive ω-3 and ω-6 polyunsaturated fatty acid metabolites in alcohol use disorder and alcoholic hepatitis patients and (2) to identify associations of serum oxylipins with clinical parameters in patients with alcohol-related liver disease. METHODS: We performed a comprehensive liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis of serum and fecal oxylipins derived from ω-6 arachidonic acid, ω-3 eicosapentaenoic acid, and docosahexaenoic acid in a patient cohort with alcohol-related liver disease. RESULTS: Our results show profound alterations in the serum oxylipin profile of patients with alcohol use disorder and alcoholic hepatitis compared to nonalcoholic controls. Spearman correlation of the oxylipins with clinical parameters shows a link between different serum oxylipins and intestinal permeability, aspartate aminotransferase, bilirubin, albumin, international normalized ratio, platelet count, steatosis, fibrosis and model for end-stage liver disease score. Especially, higher level of serum 20-HETE was significantly associated with decreased albumin, increased hepatic steatosis, polymorphonuclear infiltration, and 90-day mortality. CONCLUSIONS: Patients with alcohol-related liver disease have different oxylipin profiles. Future studies are required to confirm oxylipins as disease biomarker or to connect oxylipins to disease pathogenesis.

[Randomized controlled trial of internal heat-type acupuncture needle therapy in the treatment of post-stroke shoulder pain].

OBJECTIVE: To evaluate the effectiveness and safety of internal heat-type acupuncture needle (IHTAN) the-rapy in the treatment of post-stroke shoulder pain in apopletic patients. METHODS: According to the random number table, 96 patients with post-stroke shoulder pain were divided into IHTAN group and warm needle moxibustion group (n＝48 in each one). Jianyu (LI15), Jianliao (TE14), Jianzhen (SI9), Binao (LI14) and Ashi points (Extra) on the affected side were selected in the two groups. For patients of the IHTAN group, internal warmth controllable acupuncture needles were inserted into the above-mentioned acupoints, and then connected to an internal heat acupuncture apparatus for stimulating the acupoints at 42 ℃， 20 min every time, once a week, for 4 weeks. For patients of the warm needle moxibustion group, the above mentioned acupoints were stimulated with filiform needles attached with an ignited moxa-stick, once every other day, for 4 weeks. If the shoulder pain disappeared or basically disappeared, it was considered to be healed, if the pain was relieved, it was considered to be effective, ot-herwise, it was considered to be ineffective. The incidence of local skin injury including burn, empyrosis, silt blue, hematoma and infection, the heart rate, respiration, blood pressure, oxyhemoglobin saturation, blood routine (hemoglobin level, white blood cell [WBC] count, platelet count), creatase and dipolymer levels were recorded or detected. Additionally, the patients' satisfaction rate about the treatment environment was recorded. RESULTS: Following the treatment, of the 45 and 47 cases in the warm needle moxibustion and IHTAN groups, 5 (11.11%) and 20 (42.55%) were cured, 26(57.78%) and 21(44.68%) experienced marked improvement, and 14 (31.11%) and 6 (12.77%) had no apparent changes in their shoulder pain severity, with the total effective rates being 68.89% and 87.23%, respectively. The curative rate and total effective rate of the IHTAN group were significantly higher than those of the warm needle moxibustion group (P<0.01，P<0.05). The incidence of skin injury of the IHTAN group was evidently lower than that of the warm needle moxibustion group (P<0.01), and the patients' therapeutic environment satisfaction rate was remarkably higher in the IHTNA group than in the warm needle moxibustion group (P<0.05). No significant differences were found between the two groups and between pre- and post-treatment in each group in the heart rate, respiration frequency, systolic and diastolic pressures, oxyhemoglobin saturation, hemoglobin content, WBC count, platelet count, and plasma dipolymer, creatine kinase, lactic dehydrogenase, and beta-hydroxybutyrate dehydrogenase levels (P>0.05). CONCLUSION: The IHTAN therapy is effective, safe and reliable in the treatment of post-stroke shoulder pain. In terms of the incidence of skin injury and the satisfaction degree of therapeutic environment, the internal heat-type acupuncture needle therapy is obviously superior to the warm needle moxibustion therapy.

[Short-term and long-term therapeutic effects of internal heat-type acupuncture needle therapy combined with acupoint injection of O3 for post-stroke shoulder pain].

OBJECTIVE: To observe the short-term and long-term therapeutic effects of internal heat-type acupuncture needle (IHTAN) therapy combined with acupoint injection of O3for post-stroke shoulder pain in apopletic patients. METHODS: Patients with post-stroke shoulder pain were divided into warm needle moxibustion ＋ acupoint injection group (29 cases), acupoint injection group (30 cases) and IHTAN＋acupoint injection group (29 cases) according to the random number table. For acupoint injection, O3 solution (3 mL, 30 µg/mL) was injected into Jianyu (LI15), Jianliao (SJ14), Jianzhen (LI9), Binao (LI14) and Ashi points (4-6 acupoints every time) on the affected side, once every other day for 4 weeks. For warm needle moxibustion, the above mentioned acupoints were stimulated with filiform needles attached with an ignited moxa-stick, once every other day for 4 weeks. For IHTAN, the internal warmth controllable acupuncture needles were inserted into the above mentioned acupoints on the affected side, and then connected to an internal heat acupuncture apparatus for stimulating the acupoints at 42 ℃， 20 min every time, once a week, for 4 weeks. The severity of shoulder pain was assessed by using visual analogue scale (VAS, 0-10 points), the upper limb joint motion function evaluated using Fugl-Meyer assessment scale (FMA, 0－66 points), and the ability of daily living activities (ADL) evaluated using Barthel index (0－100 points) at the ends of the 2nd and 4th week as well as the 6th month after the treatment. If the shoulder pain disappeared or basically disappeared, it was considered to be healed. If the pain was relieved, it was considered to be effective. Otherwise, it was considered to be ineffective. RESULTS: At the ends of the 2nd and 4th week as well as the 6th month after the treatment, the VAS scores of the IHTAN＋acupoint injection group were significantly lower than those of the warm needle moxibustion＋acupoint injection and acupoint injection groups (P<0.05), and the FMA and ADL scores were significantly higher in the IHTAN＋acupoint injection group than in the other two groups (P<0.05). No significant differences were found between the warm needle moxibustion＋acupoint injection and the acupoint injection groups in the scores of VAS, FMA and ADL (P>0.05). Of the 29, 30 and 29 cases in the warm needle moxibustion＋acupoint injection, acupoint injection and IHTNA＋acupoint injection groups, 1, 0 and 7 cases at the 2nd week, 3, 2 and 12 cases at the 4th week, 4, 2 and 15 cases at the 6th month were cured; 15, 14 and 16 cases at the 2nd week, 17, 17 and 13 cases at the 4th week, and 18, 18 and 12 cases at the 6th month experienced marked improvement; 13, 16 and 6 cases at the 2nd week, 9, 11 and 4 cases at the 4th week, 7, 10 and 2 cases at the 6th month had no apparent changes in their shoulder pain severity, with the total effective rates at the 4th week and 6th month being 68.97% and 75.86%, 63.33% and 66.60%, and 86.21% and 93.10%, respectively. CONCLUSION: The internal heat-type acupuncture needle therapy combined with O3 acupoint injection has obvious short-term and long-term therapeutic effects for post-stroke shoulder pain and is obviously superior to warm needle moxibustion＋ acupoint injection and simple acupoint injection in relieving shoulder pain and improving upper limb motion function.

Differentially expressed genes of HepG2 cells treated with gecko polypeptide mixture.

Gecko (Gekko japonicus) extracts have been used in traditional Chinese medicine for many years. It has been proven that the gecko polypeptide mixture (GPM) extracted from gecko can inhibit the growth of multiple types of tumor cells. In order to investigate the possible anti-tumor molecular mechanisms of GPM, we used RNA-seq technology to identify the differentially expressed genes (DEGs) of human hepatocellular carcinoma (HCC) HepG2 cells treated with or without GPM. MTT assay was used to detect the viability of HepG2 cells. DAPI fluorescence staining was performed to observe morphological changes in the nuclei of HepG2 cells. Western blot analysis was applied to observe the expressions of apoptosis-related and endoplasmic reticulum stress (ERS)-related proteins in HepG2 cells. Flow cytometry assay was performed to detect the apoptosis and reactive oxygen species (ROS) in HepG2 cells. Our results showed that GPM inhibited HepG2 cells proliferation and induced the apoptosis of HepG2 cells. RNA-seq analysis suggested that the ER-nucleus signaling pathway involved in the anti-cancer molecular mechanism of GPM. Therefore, GPM may induce apoptosis in HepG2 cells via the ERs pathway.

Perception of Non-surgical Periodontal Treatment in Individuals Receiving or Not Receiving Local Anaesthesia.

PURPOSE: Patients might refuse the offer of local anaesthesia (LA) administration prior to dental treatment. This study investigates subjective discomfort perception during non-surgical mechanical periodontal therapy delivered with or without LA. MATERIALS AND METHODS: Sixty patients with mild to moderate chronic periodontitis and prior periodontal debridement experience were randomly enrolled in nonsurgical therapy of a quadrant with or without LA administration. Patients were free to comply or not with the allocated LA arrangement. Visual analogue scales (VAS) of discomfort perception at various stages of the treatment as well as overall satisfaction were recorded. Demographic, psychosocial and periodontal parameters were recorded. RESULTS: Thirty-one patients undergoing nonsurgical periodontal therapy not receiving (LA-) and 29 participants receiving LA (LA+) were studied. Compared to LA- patients, LA+ individuals perceived less discomfort during treatment and reported less dental anxiety (p<0.05). Lower overall treatment satisfaction was associated with prior unpleasant periodontal experience (p=0.047). Overall, debridement discomfort was associated with not receiving LA, noncompliance with the pain control regimen allocated, longer treatment duration, greater gingival inflammation and a higher percentage sites with probing pocket depths≥5 mm (p<0.05). CONCLUSION: Clinicians should be aware that patients who refuse LA can experience higher dental anxiety and therefore may require various pain control strategies for comfort during nonsurgical periodontal therapy, which, if not employed, can lead to less periodontal treatment satisfaction.

[Mining rules on determination of four properties based on traditional Chinese medicine functional combination].

OBJECTIVE: It laid the foundation of the large sample data mining for a comprehensive summary concerning four properties theory of traditional Chinese medicine (TCM), and also provided theory clues on determination of four properties for the new resource development of TCM and the clinical use of Chinese medicine. METHOD: Four properties data of 8 980 Chinese medicines from "Chinese herbal medicine (CHM)" and associated function index data were chose as data sets. Then, the IBM SPSS Clementine 14.1 data mining platform and Apriori model were adopted to mining classification-association rules, setting the minimum support threshold of rule antecedent and the minimum confidence threshold as 0.5% and 60%. RESULT: 11 classification-association rules involved in warm, cold and mild natures were found. CONCLUSION: It was discovered that the TCM with functions of "dispelling wind-cold, warming the middle, stopping pain and expelling wind-removing dampness, tonifying kidney yang, unblocking meridians and expelling wind-removing dampness, dispelling cold to stop pain, strengthening sinews-bones and expelling wind-removing dampness" was likely warm-natured, with functions of "tonifying the lung" was likely mild-natured, and with functions of " clearing heat and drying dampness, clearing heat and purging fire, eliminating restlessness" was likely cold-natured.
