Comparison of Effects of Liuzijue Exercise and Conventional Respiratory Training on Patients after Cardiac Surgery: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the feasibility and safety of Liuzijue exercise (LE) for the clinical effect in patients after cardiac surgery. METHODS: Totally 120 patients who underwent cardiac surgery and were admitted to the Cardiothoracic Intensive Care Unit of Nanjing Drum Tower Hospital between July and Oclober, 2022 were allocated to the LE group, the conventional respiratory training (CRT) group, and the control group by a random number table at a ratio of 1:1:1; 40 patients in each group. All patients received routine treatment and cardiac rehabilitation. LE group and CRT group respectively performed LE and CRT once a day for 30 min for 7 days. Control group did not receive specialized respiratory training. The forced vital capacity, forced expiratory volume in 1 s, peak inspiratory flow rate, peak expiratory flow rate, maximum inspiratory pressure, maximum expiratory pressure, modified Barthel index (MBI), and Hamilton Rating Scale for Anxiety (HAM-A) were evaluated before, after 3 and 7 days of intervention. In addition, the postoperative length of hospital stay (LOS) and the adverse events that occurred during the intervention period were compared. RESULTS: A total of 107 patients completed the study, 120 patients were included in the analysis. After 3 days of intervention, the pulmonary function, respiratory muscle strength, MBI and HAM-A of all 3 groups improved compared with that before the intervention (P<0.05 or P<0.01). Compared with the control group, pulmonary function and respiratory muscle strength were significantly improved in the CRT and LE groups (P<0.05 or P<0.01). MBI and HAM-A were significantly improved in the LE group compared with the control and CRT groups (P<0.05 or P<0.01). On the 7th day after intervention, the difference was still statistically significant (P<0.01), and was significantly different from that on the 3rd day (P<0.05 or P<0.01). In addition, on the 7th day of intervention, the pulmonary function and respiratory muscle strength in the LE group were significantly improved compared with those in the CRT group (P<0.01). MBI and HAM-A were significantly improved in the CRT group compared with the control group (P<0.01). There were no significant differences in postoperative LOS among the 3 groups (P>0.05). No training-related adverse events occurred during the intervention period. CONCLUSIONS: LE is safe and feasible for improving pulmonary function, respiratory muscle strength, the ability to complete activities of daily living and for relieving anxiety of patients after cardiac surgery (Registration No. ChiCTR2200062964).

Treatment Progress in Diminished Ovarian Reserve: Western and Chinese Medicine.

Diminished ovarian reserve (DOR), generally defined as a decreased number or quality of oocytes, has a significant impact on quality of life and fertility in women. In recent years, the incidence of DOR has been increasing and the ages of patients are younger. The search for an effective DOR treatment has emerged as one of the preeminent research topics in reproductive health. An effective DOR therapy would improve ovarian function, fertility, and quality of life in patients. In this review we evaluated DOR treatment progress both in Western medicine and Chinese medicine, and elucidated the characteristics of each treatment.

Evolution and significance of the psychosomatic model in gastroenterology.

The biomedical model, which limits itself to finding the attributions of organic disease, is challenged by gastrointestinal (GI) symptoms. Simultaneously, physicians' attribution of GI symptoms to underlying psychological issues is not readily accepted by patients and can negatively affect the clinical rapport between doctor and patient. In reality, psychosocial aspects are involved in many functional disorders and organic diseases, not just in mental disorders. Time is overdue for gastroenterologists to recognise the inadequacy and limitations of conventional gastroenterology and consider the role of psychological, social and biological variables throughout the entire clinical course of the illness, as is shown in George Engel's model. This review discusses the following: (1) the current challenges of using the conventional clinical model for both functional and organic GI illness, (2) the inadequacy and limitations of explaining GI symptoms simply as psychological disorders, (3) the exploration of the symptom-centred, stepped reattribution clinical model, (4) the clarification of psychosomatic medical concepts for use in gastroenterology, and (5) the significance of a systematic and interdisciplinary framework for a comprehensive psychosomatic model in gastroenterology.

Brown adipose tissue activation with ginsenoside compound K ameliorates polycystic ovary syndrome.

BACKGROUND AND PURPOSE: Polycystic ovary syndrome (PCOS) is a common metabolic and endocrine disease affecting women of reproductive age. Due to its complex aetiology, there is no currently effective cure for PCOS. Brown adipose tissue (BAT) activity is significantly decreased in PCOS patients, and BAT activation has beneficial effects in animal models of PCOS. Here, we investigated the effect of ginsenoside compound K (CK) in an animal model of PCOS and its mechanism of BAT activation. EXPERIMENTAL APPROACH: Primary brown adipocytes, Db/Db mice and dehydroepiandrosterone (DHEA)-induced PCOS rats were used. The core body temperature, oxygen consumption, energy metabolism related gene and protein expression were assessed to identify the effect of CK on overall energy metabolism. Oestrous cycle, serum sex hormone, ovarian steroidogenic enzyme gene expression and ovarian morphology were also evaluated following CK treatment. KEY RESULTS: Our results indicated that CK treatment could significantly protect against body weight gain in Db/Db mice via BAT activation. Furthermore, we found that CK treatment could normalize hyperandrogenism, oestrous cyclicity, normalize steroidogenic enzyme expression and decrease the number of cystic follicles in PCOS rats. Interestingly, as a potential endocrine intermediate, C-X-C motif chemokine ligand-14 protein (CXCL14) was significantly up-regulated following CK administration. In addition, exogenous CXC14 supplementation was found to reverse DHEA-induced PCOS in a phenotypically similar manner to CK treatment. CONCLUSION AND IMPLICATIONS: In summary, CK treatment significantly activates BAT, increases CXCL14 expression and ameliorates PCOS. These findings suggest that CK might be a potential drug candidate for PCOS treatment.

To analyze the research status of acupuncture and moxibustion for cancer at home and abroad in the past 45 years by using bibliometric and scientific knowledge map methods，and explore the development trends in future. The literature of acupuncture and moxibustion for cancer was retrieved from CNKI and Web of Science (WOS) till December 31, 2020 since the database establishment, and CiteSpace and VOSviewer software were used to perform visual map analysis through cooperation network, keyword co-occurrence, keyword timeline, keyword emergence and other methods. Totally, 1 585 literature in CNKI and 1 564 literature in WOS were included, and the annual publication amount showed a fluctuating upward trend. Cooperation between countries was centered on China and the United States, and there was relatively little cooperation among different institutions. The analysis of keyword and cited literature showed that researches focused on the control of acupuncture and moxibustion therapy on cancer complications and adverse reactions of western medicine. The main research types in WOS were systematic review and randomized controlled trial (RCT), while in CNKI was review, depth studies on mechanism of acupuncture and moxibustion for cancer were rare. The concern about the quality of life of cancer patients may become research emphasis in the field of acupuncture and moxibustion for cancer in future, and the research scope tends to integrative and holistic oncology.

[Discussion on registry study of acupuncture-moxibustion for malignant pleural effusion].

Malignant pleural effusion (MPE) is one of the common complications of tumor. Acupuncture-moxibustion therapy has several advantages for treatment of MPE. Acupuncture is regarded as a complex individualized intervention, and its characteristics of TCM is difficult to be reflected by strict randomized controlled trials. The registry study provides more possibilities for the data collection of individualized diagnosis and treatment under the guidance of the overall concept and syndrome differentiation, and is more suitable for data management and collection of large samples and multi-center trials in the real-world study. It has become an opportunity to carry out real-world study of acupuncture for MPE. There are many challenges in the registry study of acupuncture for MPE. However, it is of great significance to collect real-world data of acupuncture for MPE to improve the clinical effect of MPE and provide a new clinical research method for acupuncture in tumors and related complications.

[Adjuvant therapy of moxibustion combined with Wenyang Lishui formula for peritoneal effusion of ovarian malignant tumors].

OBJECTIVE: To observe the clinical efficacy of adjuvant therapy of moxibustion combined with Wenyang Lishui formula for peritoneal effusion of ovarian malignant tumors. METHODS: Sixty patients with peritoneal effusion of ovarian malignant tumors were randomly divided into an observation group and a control group, 30 cases in each group. The patients in the control group were treated with intravenous infusion of paclitaxel liposome at the first day and cisplatin at the 2nd to 4th day, 21 days as a course of treatment, and 4 courses were given. Based on the treatment of the control group, the patients in the observation group were treated by moxibustion combined with Wenyang Lishui formula. Moxibustion was applied at Mingmen (GV 4), Pishu (BL 20), Shenshu (BL 23), Shenque (CV 8), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Zhongji (CV 3), each acupoint for 30 min, once a day for 12 weeks. Wenyang Lishui formula was taken twice orally, one dose a day, 2 weeks as a course of treatment, and 6 courses were given. The levels of , , and / in peripheral blood were measured before and after 12-week treatment in the two groups. The changes of peritoneal effusion volume and Karnofsky performance status scale (KPS) score before and after treatment were compared between the two groups, and the clinical efficacy of the two groups was evaluated. RESULTS: The symptom improvement rate was 96.7% (29/30) and overall effective rate was 86.7% (26/30) in the observation group, which were significantly superior to those in the control group [80.0% (24/30) and 56.7% (17/30), P<0.05]. After treatment, the levels of , and / in peripheral blood were significantly increased in the observation group (P<0.01), there was no significant difference in the control group before and after treatment (P>0.05), and the increase in the observation group was significantly higher than that in the control group (P<0.05). After treatment, the volume of peritoneal effusion in the two groups was decreased (P<0.01), and the reduced volume in the observation group was higher than that in the control group (P<0.05). After treatment, KPS scores were increased significantly in both two groups (P<0.01), and the increase in the observation group was higher than that in the control group (P<0.05). The incidence rate of adverse reactions in the observation group was lower than that in the control group [23.3% (7/30) vs 53.3% (16/30), P<0.05]. CONCLUSION: Moxibustion combined with Wenyang Lishui formula could effectively improve the immune function, reduce the volume of peritoneal effusion, improve the symptom improvement rate, overall effective rate and the quality of life, and reduce the incidence of adverse reactions in chemotherapy of patients with peritoneal effusion of ovarian malignant tumors.

Inhibition of Triple-Negative Breast Cancer Tumor Growth by Electroacupuncture with Encircled Needling and Its Mechanisms in a Mice Xenograft Model.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer without effective targeted drugs. While breast cancer patients often use acupuncture for the relief of cancer-induced pain or the side effects of chemo- or radiation therapy, little information is known regarding the direct effects of electroacupuncture on TNBC tumor and its potential mechanisms. Here, we created a mice model of TNBC and electroacupuncture with encircled needling around the tumors was given to the animals daily for 3 weeks at 15-20 Hz (3 min, each time). For sham electroacupuncture control, the skin was punctured to a depth of 5 mm and then the needle was quickly withdrawn without electrical stimulation or manual needle manipulation. We found that electroacupuncture significantly inhibited TNBC tumor growth and the inhibitory rate increased gradually overtime. Mechanistic analysis showed that electroacupuncture inhibited tumor angiogenesis by reducing the expression of vascular endothelial growth factor A (VEGF-A), its receptor VEGF-R and neuropilin 1 (NRP-1). Electroacupuncture also led to a significant decrease of matrix metalloproteinase-2 (MMP-2) expression and an increase of tissue inhibitor of MMP (TIMP-2) expression. Additionally, the expression of semaphorin 3A (Sema3A) and nerve growth factor receptor (NGFR) p75 in TNBC tissue was significantly upregulated in response to electroacupuncture. Furthermore, tumor necrosis factor (TNF)-alpha level in the serum was dramatically reduced after electroacupuncture. These results showed that electroacupuncture could directly inhibit TNBC tumor growth through the inhibition of proteins related to tumor angiogenesis and extracellular matrix, the suppression of TNBC-induced inflammation and the upregulation of nerve growth factor receptors.

Utilising network pharmacology to explore the underlying mechanism of Wumei Pill in treating pancreatic neoplasms.

BACKGROUND: Wumei Pill (WMP), a famous herbal formula, has been widely used to treat digestive system diseases in clinical practice in China for centuries. We have found a correlation between the indications of WMP and the typical symptoms of pancreatic neoplasms. However, the pharmacological mechanisms of WMP still remain unknown. METHODS: In the present work, we used a network pharmacological method to predict its underlying complex mechanism of treating pancreatic neoplasms. Firstly, we obtained relative compounds of WMP based on TCMSP database, TCM database@Taiwan and TCMID database and collected potential targets of these compounds by target fishing. Then we built the pancreatic neoplasms target database by CTD, TTD, PharmGKB. Based on the matching results between WMP potential targets and pancreatic neoplasms targets, we built a PPI network to analyze the interactions among these targets and screen the hub targets by topology. Furthermore, DAVID bioinformatics resources were utilized for the enrichment analysis on GO_BP and KEGG. RESULTS: A total of 80 active ingredients and 77 targets of WMP were picked out. The results of DAVID enrichment analysis indicated that 58 cellular biological processes (FDR < 0.01) and 17 pathways (FDR < 0.01) of WMP mostly participated in the complex treating effects associated with proliferation, apoptosis, inflammatory response and angiogenesis. Moreover, 17 hub nodes of WMP (PTGS2, BCL2, TP53, IL6, MAPK1, EGFR, EGF, CASP3, JUN, MAPK8, MMP9, VEGFA, TNF, MYC, AKT1, FOS and TGFB1) were recognized as potential targets of treatments, implying the underlying mechanisms of WMP acting on pancreatic neoplasms. CONCLUSION: WMP could alleviate the symptoms of pancreatic neoplasms through the molecular mechanisms predicted by network pharmacology. This study proposes a strategy to elucidate the mechanisms of Traditional Chinese Medicine (TCM) at the level of network pharmacology.

Chlorinated-Methylsiloxanes in Shengli Oilfield: Their Generation in Oil-Production Wastewater Treatment Plant and Presence in the Surrounding Soils.

In two oil-wastewater treatment stations of Shengli Oilfield, cyclic volatile methylsiloxanes (cVMS, D4-D6) in the wastewater stream were found to undergo chlorination during electro-oxidation process for wastewater containing chlorine ions (16.1-42.0 g/L). Their converted fractions were 4.71-28.0% for monochlorinated D4-D6 and 0.22-7.96% for dichlorinated D4, which were ∼2 orders of magnitude higher than those for hydroxylated products. Furthermore, portions of chlorinated methylsiloxanes retained in excess sludge were released to the surrounding soils. In soil samples ( n = 500), chlorinated methylsiloxanes concentrations (

Sources and Fate of Cyclic Phenylmethylsiloxanes in One Municipal Wastewater Treatment Plant and Biosolids-Amended Soil.

cis-/ trans-2,4,6-Triphenyl-2,4,6-trimethylcyclotrisiloxanes ( cis-P3 and trans-P3) and cis-/ trans-2,4,6,8-tetraphenyl-2,4,6,8-tetramethylcyclotetrasiloxanes ( cis-P4 and trans-P4a,b,c) were detected in personal care products [

Plant phenolics are detoxified by prophenoloxidase in the insect gut.

Plant phenolics are a group of important secondary metabolites that are toxic to many animals and insects if ingested at high concentrations. Because most insects consume plant phenolics daily, they have likely evolved the capacity to detoxify these compounds. Here, we used Drosophila melanogaster, Bombyx mori and Helicoverpa armigera as models to study the metabolism of plant phenolics by prophenoloxidases. We found that insect foreguts release prophenoloxidases into the lumen, and that the survival of prophenoloxidase-deletion mutants was impaired when fed several plant phenolics and tea extracts. Using l-DOPA as a model substrate, biochemical assays in large Lepidopteran insects demonstrated that low levels of l-DOPA are rapidly metabolized into intermediates by phenoloxidases. Feeding with excess l-DOPA showed that the metabolic intermediate 5,6-dihydroxyindole reached the hindgut either by passing directly through the midgut, or by transport through the hemolymph. In the hindgut, 5,6-dihydroxyindole was further oxidized by prophenoloxidases. Intermediates exerted no toxicity in the hemocoel or midgut. These results show that plant phenolics are not toxic to insects unless prophenoloxidase genes are lost or the levels of phenolics exceed the catalytic activity of the gut prophenoloxidases.

Enhancement of radiosensitivity of lung adenocarcinoma using a decoction from the Fuzhengzengxiao formula.

OBJECTIVE: To study the effects of a decoction of Fuzhengzengxiao formula on lung adenocarcinoma regarding the inflammatory protein S100A9 known to enhance cancer cell sensitivity. METHODS: A nude mouse model of human lung adenocarcinoma was established. The mice were randomly divided into four groups using the random number table method: Group I, control; Group II, treatment with a decoction of the Fuzhengzengxiao formula alone; Group III, treatment with radiotherapy alone; and Group IV, treatment with radiotherapy plus a decoction of Fuzhengzengxiao formula. When the tumor body was 1 cm3 in diameter, the tumor bearing mice in Groups III and IV were irradiated at a single dose of 10 Gy and the tumor inhibition rate was evaluated. The expression of S100A9 was determined using Western blotting and q-PCR (Real-time Quantitative PCR Detecting System). The sensitivity of cells containing RNAi S100A9 to radiotherapy was evaluated using the Click multiple target model,and the cell cycle was analyzed using flow cytometry. RESULTS: Relative to the control group, the expression of S100A9 in the tumors in each treatment group was decreased, especially in Group IV. The sensitizing enhancement ratio (SER) Dq was > 1 after RNAi S100A9; it decreased the surviving fraction after a 2 Gy dose exposure,and also the D0 and Dq of the tumor cells; in addition, the radiosensitivity of G2/M cells was significantly increased. CONCLUSION: The decoction of the Fuzhengzengxiao formula downregulated the expression of S100A9 in lung adenocarcinoma cells.

[Expression of AMPA receptors and related protein in immobilization stressed rats and effect of Xiaoyaosan].

AIM: To observe protein expression changes of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor and related regulatory protein in the hippocampus and amygdala in chronic immobilization stressed rat and Xiaoyaosan's regulatory effect. METHODS: Rats were tied 3 h per day to establish immobilization stress condition and treatment with Xiaoyaosan. After 7 days and 21 days stress, the protein expression of AMPA receptor subunit (GluR2/3), N-ethylmaleimide sensitive factor (NSF) and protein interacting with C-kinase 1 (PICK1) in hippocampus and amygdala were detected by using Western blot techniques. RESULTS: The expression of GluR2/3, NSF in dentate gyrus (DG) and amygdala were markedly attenuated (P < 0.05) and PICK1 in CA1 region were significantly increased (P < 0.05) in 7 d immobilization stressed rats while 7 days xiaoyaosan treatment showed an effective regulatory result to PICK1's changes. Under 21 days immobilization stressed condition, the expression of GluR2/3, NSF in CA1 region showed an increasing trend, and GluR2/3 showed a markedly increase (P < 0.01), but showed an significantly decreased trend in amygdala, Xiaoyaosan showed an effective result to such changes above (P < 0.05). The expression of PICK1 showed increasing trend in amygdala and xiaoyaosan could lower its expression (P < 0.05). CONCLUSION: There are different trends of the expression of AMPA receptor in repeat short-term stress versus chronic immobilization stress, and in hippocampal CA1 region versus amygdala. Xiaoyaosan has better regulation effect on the expression of AMPA receptors in the condition of chronic immobilization stress than those of repeat shortterm stress.

[Changes of central AMPA receptor subunits and related protein mRNA expression in immobilization stressed rats and effect of Xiaoyaosan on them].

OBJECTIVE: To observe the changes of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit and related regulatory protein mRNA expression in the hippocampus and amygdala in immobilization stressed rats and effect of Xiaoyaosan (XYS) on them. METHODS: Immobilization model rats were established by binding for 3 h per day and intervened with XYS, the expression of AMPA receptor subunit (GluR1-4), N-ethylmaleimide sensitive factor (NSF) and protein interacting with C-kinase 1 (PICK1) mRNA expression in model rats' CA1 and CA3 regions of hippocampus, dentate gyrus and amygdala were detected on day 7 and day 21 after modeling. RESULTS: On day 7, expression of GluR1 mRNA was significantly decreased in CA1 region (P < 0.05) and increased in CA3 region and amygdala (all P < 0.05); expression of GluR2 and GluR3 mRNA in amygdala (all P < 0.05) and GluR4 mRNA in CA1 region (P < 0.01) significantly increased, but the expression of NSF and PICK1 mRNA in amygdala only showed an increasing trend. XYS showed effective regulation on GluR4 mRNA in CA1 region (P < 0.01) and GluR1-3 mRNA expression (P < 0.05, P < 0.01) in amygdala. On day 21, the expression of GluR4 mRNA in CA1 region (P < 0.05) and GluR2 mRNA in dentate gyrus (P < 0.05) markedly lowered and expression of GluR1 mRNA in amygdala increased (P < 0.01); XYS significantly regulated the expression of GluR1 and GluR4 mRNA in CA1 region (all P < 0.05). CONCLUSION: Repeated stress in a short time shows effect on expression of AMPA receptor subunit mRNA stronger than chronic stress. The regulation of XYS to AMPA receptor subunit mRNA expression were obvious in hippocampal CA1 region and amygdala.
