RESUMEN
OBJECTIVE: To evaluate the efficacy of Guanxin Danshen Dripping Pill (GXDSDP) in treating anxiety and depression in patients with coronary heart disease (CHD). METHODS: A total of 1,428 patients diagnosed with CHD screened for anxiety, depression, and quality of life (QOL) at baseline received 0.4 g of GXDSDP treatment 3 times per day and returned for monthly reassessment. Patients were recruited after stable treatment for CHD and received assessment of General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Seattle Angina Questionnaire (SAQ) for evaluating anxiety, depression, and QOL. Patients were followed up 3 times, once every 4 weeks, during outpatient visits for 12 weeks. RESULTS: At the third follow-up (F3), the anxiety symptom of 63.79% (673/1,055) of the patients improved to sub-clinical level, and the GAD-7 score improved significantly (8.11 vs. 3.87, P<0.01); 57.52% (585/1,017) patients' depressive symptoms improved to sub-clinical level, with a significant improvement in PHQ-9 score (8.69 vs. 4.41, P<0.01) at F3. All aspects of QOL significantly improved at the end of treatment compared to those at baseline (all P<0.01) as assessed by SAQ: physical limitation (31.17 vs. 34.14), anginal stability (2.74 vs. 4.14), anginal frequency (8.16 vs. 9.10), treatment satisfaction (13.43 vs. 16.29), and disease perception (8.69 vs. 11.02). CONCLUSIONS: A fixed dosage of GXDSDP may be a potential treatment option for CHD patients comorbid with anxiety or depression. (Registration No. ChiCTR2100051523).
RESUMEN
OBJECTIVE: To observe the effect of San-Ao Decoction (, SAD) on water metabolism of bronchial asthra model mice. METHODS: Forty-five female BALB/c mice were randomly divided into control, model and SAD groups by a random number table, 15 mice in each group. A composite method with ovalbumin (OVA) sensitization and challenge was developed to establish bronchial asthma model. Mice in the control group were intraperitoneally injected with distilled water without aerosol inhalation challenge. On day 15-22, 0.3 mL SAD was administered via gastric route in SAD group, one time per day, while an equivalent volume of normal saline was used for gastric administration in the control and model groups. Changes in airway resistance in the inspiratory phase (RI-R-Area) were detected using an AniRes2005 system, and 5-h urine output was collected by metabolic cages. Histopathological changes in lung and kidney were observed by hematoxylin-eosin staining. mRNA expressions of aquaporin (AQP) 1 and AQP2 in kidney were detected by reverse transcription-polymerase chain reaction, and the protein expressions of AQP1 and AQP2 in kidney were detected by immunohistochemistry. Enzyme-linked immune sorbent assay was used to detect the OVA-specific endothelium-1 (ET-1), antidiuretic hormone (ADH), atrial natriuretic peptide (ANP), prostaglandin E2 (PGE2), and angiotensin II (Ang II) levels in serum, lung and kidney tissues, respectively. The nitric oxide (NO) contents in serum, lung, and kidney tissues were tested by chemical method, respectively. RESULTS: Compared with the control group, the serum IgE level in model group increased (P<0.01). Following the pathologic changes in lung tissue, no significant change in kidney tissue was observed among 3 groups. Compared with the control group, the mice in the model group showed elevated airway resistance during inhalation phase, higher mRNA and protein expression levels on AQP1 and AQP2 in kidney tissue and higher ET-1 levels in serum, lung and kidney tissues, ADH and ANP in lung and serum, PGE2 in kidney, Ang II in lung and kidney tissues (P<0.05 or P<0.01), but decreased in 5-h urinary output as well as NO and PGE2 contents in serum and lung tissues (P<0.05 or P<0.01). Compared with the model group, the mice in the SAD group showed a weakened airway resistance in inspiratory phase, lower mRNA and protein expressions of AQP1 and AQP2 in kidney tissues, lower levels of ET-1, ADH, ANP in serum as well as ET-1, ANP, Ang II levels in kidney tissues (P<0.05 or P<0.01), whereas 5-h urinary output, NO content in kidney, ADH, ANP and PGE2 levels in lung and Ang II in serum increased (P<0.05 or P<0.01). CONCLUSION: San-Ao Decoction can regulate the urine volume through regulating AQP1 and AQP2 expression, and the expression of these in the kidneys might be regulated by ET-1, NO and Ang II.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a major cause of chronic liver disease. The Chinese herbal medicine (CHM) Dachaihu decoction (DCHD) has been proved to treat NAFLD with good efficacy in previous studies. Based on the TCM principle of formula formation, we divided DCHD into soothing liver part, invigorating spleen part, and dredging intestine part. Marshall officially proposed the concept of "intestinal-hepatic axis", which systematically explains the interactions between the intestine and liver. We hypothesized that the effect of CHM on NAFLD is achieved by regulating the liver and intestine. Thus, we aimed to investigate the possible effect of a CHM formula on NAFLD in a rat model. AIM: To investigate the effects of a CHM formula (a decoction of Chinese thorowax root, scutellaria root, and white peony root) on NAFLD and its regulatory effect on the "intestinal-liver" axis. METHODS: Sixty rats were randomly divided into control, model, pioglitazone hydrochloride (PH), and CHM (a decoction of Chinese thorowax root, scutellaria root, and white peony root) groups. An NAFLD rat model was established using a high-fat high-fructose diet for 16 wk. From the 13th week, rats were administered with PH or a decoction of Chinese thorowax, scutellaria, and white peony root (CHM group) for 4 wk. Rats in the control group and model group were administered with an equal volume of distilled water. At the end of the study, blood was collected via the abdominal aorta. Liver tissues were harvested and any morphological changes were observed by hematoxylin-eosin (HE) staining, Oil red O staining, and Masson staining. In addition, blood lipids, liver function markers, and triglyceride (TG) in liver tissues were analyzed. The levels of transforming growth factor-ß1 (TGF-ß1), tumor necrosis factor-α (TNF-α), Toll-like receptor-4 (TLR4), and nuclear factor-kappa B (NF-кB) in liver tissues and secreted immunoglobulin A (sIgA) in intestinal tissues were analyzed by ELISA, and protein and mRNA expression of occludin and zonula occludens-1 (ZO-1) in the intestine were measured using Western blot and reverse transcription-quantitative polymerase chain reaction, respectively. The endotoxin level in plasma was detected by endpoint chromogenic assay. RESULTS: Compared to the normal control group, the liver coefficient, serum TG, total cholesterol (TC), low density lipoprotein (LDL), aspartate aminotransferase (AST), and alanine aminotransferase (ALT), blood glucose, plasma endotoxin, and the levels of TG, TNF-α, TGF-ß, NF-kB, and TLR4 in liver tissues increased significantly in the model group, while serum high density lipoprotein (HDL), intestinal sIgA, and protein and mRNA expression of occludin and ZO-1 decreased significantly in the model group (P < 0.01). PH and CHM attenuated the elevated liver coefficient, serum TG, TC, LDL, AST, and ALT, blood glucose, plasma endotoxin, and the levels of TG, TNF-α, TGF-ß, NF-kB, and TLR4 in liver tissues and increased serum HDL levels compared to the model group (P < 0.01). Intestinal sIgA and the protein and mRNA expression of intestinal occludin and ZO-1 were significantly increased in the PH group compared to the model and CHM groups (P < 0.01). CONCLUSION: The decoction of Chinese thorowax root, scutellaria root, and white peony root is beneficial in regulating lipid metabolism and liver function, which indicates that it has a good effect on the liver. To a certain extent, this CHM formula can affect both the liver and intestine, while its effect on the liver is superior to that on the intestine.

The 4 properties of Chinese materia medica refer to cold, hot, warm, and cool. In the present study, the effects of the Coptis, the prepared aconite root, and dried ginger rhizome were compared with regard to the rectal and skin temperature changes of the related body surface acupuncture points (Dazhui, Zhiyang, Mingmen, Zhongwan, and Shenque). The investigation aimed to explore the thermal sensitive points, which can reflect the cold and hot properties of the Chinese herbs. This study showed that the prepared aconite root and dried ginger rhizome exhibited a warming effect on the body temperature, whereas the warming sensitive points were Zhongwan, Shenque, Dazhui, and Zhiyang. Coptis exhibited both a warming and a cooling effect on the body temperature, and the cooling sensitive point was Dazhui. The concomitant effect of these three Chinese herbs on the regulation of the body temperature was reflected by Dazhui. However, there are still some limitations and one-sidedness. For instance, the cold and hot property of some herbs cannot be fully reflected through relevant acupoints on the conception and governor vessels. More detecting sites such as ears and internal organs will be selected for further exploration of Chinese herbs' cold and hot property.
RESUMEN
OBJECTIVE: To investigate whether emodin exerts protective effects on mouse with allergic asthma. METHODS: A mouse model of allergic airway inflflammation was employed. The C57BL/6 mice sensitized and challenged with ovalbumin (OVA) were intraperitoneally administered 10 or 20 mg/kg emodin for 3 days during OVA challenge. Animals were sacrificed 48 h after the last challenge. Inflammatory cell count in the bronchoalveolar lavage fluid (BALF) was measured. The levels of interleukin (IL)-4, IL-5, IL-13 and eotaxin in BALF and level of immunoglobulin E (IgE) in serum were measured with enzyme-linked immuno sorbent assay kits. The mRNA expressions of IL-4, IL-5, heme oxygenase (HO)-1 and matrix metalloproteinase-9 (MMP-9) were determined by real-time quantitative polymerase chain reaction. RESULTS: Emodin induced significant suppression of the number of OVA-induced total inflammatory cells in BALF. Treatment with emodin led to significant decreases in the levels of IL-4, IL-5, IL-13 and eotaxin in BALF and total IgE level in serum. Histological examination of lung tissue revealed marked attenuation of allergen-induced lung eosinophilic inflammation. Additionally, emodin suppressed IL-4, IL-5 and MMP-9 mRNA expressions and induced HO-1 mRNA expression. CONCLUSION: Emodin exhibits anti-inflammatory activity in the airway inflammation mouse model, supporting its therapeutic potential for the treatment of allergic bronchial asthma.

Background. To investigate the specific link between lung and large intestine. Methods. Rat COPD-like model was prepared. Mirabilite or Chinese rhubarb was administrated intragastrically to stimulate the large intestine. Histological analysis of lung inflammation was assessed. The tissues levels of SP, VIP, NK1R, VIPR1, and VIPR2 were measured by using ELISA kits. In addition, mouse model of allergic asthma was prepared. Mirabilite was administrated intragastrically to stimulate the large intestine. Airway responsiveness and lung inflammation were assessed. The tissues levels of SP, VIP, NKA, NKB, NK1R, VIPR1, and VIPR2 were measured by using ELISA kits. Results. Stimulating the intestine with Mangxiao or Dahuang, SP, NK-1R, VIP, VIPR1, and VIPR2 were significantly increased in intestine tissues of rats with COPD and mice with asthma. Meanwhile, the SP and NK1R were significantly decreased, while VIP, VIPR1, and VIPR2 were significantly increased in lung tissues. An abnormal secretion of SP and VIP can be observed in other tissues; however, no marked changes were found in the receptors. The NKA and NKB levels were similar in lung tissues of mice with asthma among groups. Conclusions. Stimulating intestine with Mangxiao or Dahuang can specifically regulate the secretion of SP, VIP, and the receptors in lung tissues.
RESUMEN
Zheng classification study based on infrared thermal imaging technology has not been reported before. To detect the relative temperature of viscera and bowels of different syndromes patients with pulmonary disease and to summarize the characteristics of different Zheng classifications, the infrared thermal imaging technology was used in the clinical trial. The results showed that the infrared thermal images characteristics of different Zheng classifications of pulmonary disease were distinctly different. The influence on viscera and bowels was deeper in phlegm-heat obstructing lung syndrome group than in cold-phlegm obstructing lung syndrome group. It is helpful to diagnose Zheng classification and to improve the diagnosis rate by analyzing the infrared thermal images of patients. The application of infrared thermal imaging technology provided objective measures for medical diagnosis and treatment in the field of Zheng studies and provided a new methodology for Zheng classification.
RESUMEN
OBJECTIVE: To investigate the synergistic anti-inflammatory effect of Radix Platycodon in combination with herbs for cleaning-heat and detoxification and its mechanism for Fel-targeting. METHODS: Forty Wistar rats were randomly divided into five groups (8 per group): the sham-operated group, model group, Radix Platycodon group, Flos Lonicera and Fructus Forsythia (LF) group, and Radix Platycodon, Flos Lonicera and Fructus Forsythia combination (PLF) group, using a random number table. A rat chronic obstructive pulmonary disease (COPD) model was established by passive smoking and intratracheal instillation of lipopolysaccharide (LPS). The treatments started from the 15th day of passive smoking for a total duration of 14 days. At the end of the treatment, changes in the following measurements were determined: lung histopathology, inflammatory cytokines including tumor necrosis factor α (TNF-α), transforming growth factor ß (TGF-ß) and interleukin IL-1ß (IL-1ß) in bronchoalveolar lavage fluid (BALF), and mRNA expression of endogenous active substance intestinal trefoil factor 3 (TFF3) in the lung tissue. RESULTS: Light microscopy showed that compared with the sham-operated group, rats in the COPD model group had disrupted alveolar structure, collapsed local alveoli, significantly widened or even fused alveolar septa, and massive infiltration of inflammatory cells in the alveolar wall and interstitium. In addition, significant bronchial epithelium hyperplasia, partially shed epithelia, and marked inflammatory cell infiltration in the bronchial wall and its surrounding tissues were noticed. Electron microscopy showed that rats in the model group had degeneration of alveolar type II epithelial cell; reduction, breakage or even loss of cell surface microvilli; swollen mitochondria with disappearing cristae and vacuole-like structure; and, increased secondary lysosomes in alveolar macrophages. The TNF-α, TGF-ß and IL-1ß levels and white blood cell (WBC) count in BALF were significantly increased (P < 0.01 or P < 0.05) and TFF3 mRNA expression in the lung tissue was significantly reduced (P < 0.01). After treatment, the pathological morphology of lung injury was less severe in all three treatment groups. In addition, TGF-ß and IL-1ß and WBC count in BALF were decreased (P < 0.01 or P < 0.05), and TFF3 mRNA expression in the lung tissue was significantly increased in the PLF group (P < 0.01). Compared with the LF group, the IL-1ß in BALF was significantly decreased P < 0.05), and TFF3 mRNA expression was significantly increased (P < 0.05) in the PLF group. CONCLUSIONS: Radix Platycodon synergizes with herbs for cleaning-heat and detoxification in reducing inflammatory injury in a rat model of COPD. The synergistic anti-inflammatory effect is reflected in the improvement in pathological changes and in the reduction of IL-1ß levels in BALF. The mechanism of such synergistic action may be related to its effect on maintaining the TFF3 mRNA expression and Fel-targeting function.

OBJECTIVE: To examine the abilities of theanine and houpu extracts (HE) to reverse behavioral indexes (separation vocalization, stress-induced analgesia and activity). METHOD: 7-day-old chicks received IP injection of theanine and HE 30 min before being tested in the presence of three social companions or in isolation for 3-min observation period. Dependent measures were: a) Chicks were placed into an infrared ray device to calculate their spontaneous activities by a computer program b) record the separation vocalizations for every chick. c) In the experiment of stress-induced analgesia, 50 uL of formalin (0.1%) was injected into the plantar of the animal foot to index stress-induced analgesia (i. e. foot-lift frequency, foot-lift duration and peck frequency). RESULT: In the experiments, isolated chicks exhibited more vocalizations (P < 0.01) and fewer pain-related behaviors than non-isolated chicks (P < 0.01). Theanine (12.5, 25, 50 mg x kg(-1)) and HE (25 mg x kg(-1)) decrease separately the tendency (dB) of the principal frequency (P < 0.05, P < 0.01); The stress induced analgesia can be reversed by theanine in 25, 50 mg x kg(-1). Both of the materials do not affect the spontaneous activities in this chick model without causing sedation. CONCLUSION: These results suggest that theanine and HE in the dosages may be useful in modulating anxiety states. They are seems no synergism in the chick model.
