Objective To observe the effect of cupping plus Chinese medicinal fumigation on expectoration in patients with chronic obstructive pulmonary disease (COPD) due to phlegm-heat obstructing the lung. Method Eighty-two patients with COPD due to phlegm-heat obstructing the lung were randomized into a treatment group and a control group, 41 cases in each group. The control group was given regular Western medications, while the treatment group was intervened by cupping plus Chinese medicinal fumigation in addition to the treatment given to the control group, once a day, 5 d as a treatment course. The therapeutic efficacies were observed after 2 treatment courses. Result The clinical effective rate of the treatment group was higher than that of the control group, with a statistical significance (P<0.05). Conclusion Cupping plus Chinese medicinal fumigation can enhance the expectoration in patients with COPD due to phlegm-heat obstructing the lung.

Objective: To evaluate the therapeutic effects of Tuina and hyperbaric oxygen on prolapse of lumbar intervertebral disc. Methods: The included 160 cases of prolapse of lumbar intervertebral disc were allocated into a treatment group and a control group. The 100 cases in the treatment group were treated with tuina manipulation and hyperbaric oxygen. The 60 cases in the control group were treated with tuina manipulation. The total effect and scores of symptoms and signs were compared before and after treatment. Results: The total effective rate in the treatment group was 100.0%, and 83.0% in the control group. Conclusion: Tuina and hyperbaric oxygen had excellent effects on the prolapse of lumbar intervertebral disc, by improving the clinical symptoms and signs of ache and movement restriction of lower back and leg, and recovering the ability of work and daily life.

Depression is a devastating mental disorder and major depressive disorder (MDD) that afflicts 16％ of the global population at some point in their lives. Currently available classical antide-pressants (SSRIs, SNRIs, TCAs and MOIs), require a minimum of 2–4 weeks of continuous treat-ment to elicit therapeutic relief in depressed patients and are associated with high rates of non-respon-siveness, and limited duration of efficacy. Therefore, faster-acting antidepressant therapies are need-ed,particularly for patients at risk for suicide for current therapies for depression.Although the molecu-lar mechanisms underlying the pathogenesis of depression are still largely unclear, previous studies have suggested that modulators of mammalian target of rapamycin complex 1 (mTORC1) signaling may have beneficial neuroprotective and antidepressant effects. Here, we review recent advances in understanding mTORC1 signaling in depression and potential therapeutic strategies resulting from modulation of the mTORC1 signaling network. We also highlight recent studies considered to support mTORC1 signaling modulation as a rapid-acting antidepressant therapy (e.g. ketamine, scopolamine, GLYX-13, (2R,6R)-HNK, Ro-256891 etc.) and discuss future research directions. Studies on prospec-tive next-generation rapid-acting antidepressant therapies should focus on developing more selective glutamate receptors(e.g.α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors(AMPARs) agonists or activators)that activate the mTORC1 signaling pathway free of ketamine's adverse effects.

Objective To investigate the feasibility of pig lung cancer model induced by bronchial perfusion of 3,4-benzopyrene. Methods 24 experimental pig were randomly divided into model group and control group, each containing 12 cases. Experimental pigs were under the anaesthetic state, pigs in the model group were given endobronchial infusion of 3,4 - benzopyrene - corn oil mixture, pigs in control group were injected with equal capacity of corn oil.Perfusion 1 times a week for 16 weeks.In week 16,32 and 48,all experimental pig were given lung CT scans, then the lung lesions were observed.After 48 weeks, the pig lung, esophagus, and gastrointestinal tract, liver and brain and other organs were dissected, the presence of tumor formation was observed, and the mass, and experimental pig lung biopsy were given hematoxylin and eosin staining analysis. Results Lung cancers were not found in control group by both CT lung cancers and anatomy. In the model group, pulmonary CT showed space-occupying lesions with different location and size in lungs of 8 pigs, and the space-occupying lesions were confirmed as malignant tumors by pathology, including 3 cases of moderately differentiated adenocarcinoma, 2 cases of highly differentiated squamous cell carcinoma, 1 case of alveolar cell carcinoma,2 cases of adenosquamous carcinoma. Three other pigs and pigs in the control group were not found with tumor by both lung CT and anatomy. Pigs in model group were induced successfully to malignant tumor in 1 year , the total tumor formation rate was 75%,lung tumor formation rate was 66.66%. Conclusion The trachea bronchial perfusion of 3,4- benzopyrene is a simple,safe and reliable way to construct animal models of lung cancer.

Depression is one of the diseases with the highest disability rate in the world. A large number of studies have shown that the intake of unsaturated fatty acids can deal with depression while chronic overconsumption of saturated fatty acids is a risk factor for depression. It was suggested that the mechanism of saturated fatty acids inducing depression is related to the following four aspects: regulating the function which links to depression in whole brain and specific brain regions, including the hippocampus, the hypothalamic-pituitary-adrenal axis, the striatum, and the prefrontal cortex; stimulating the secretion of inflammatory factors; affecting the balance and function of metabolic regulatory hormones, including leptin, adiponectin, glucocorticoid, and insulin; inducing the disturbance of intestinal flora. This article reviews the relationship between dietary fatty acids and depression, and the possible mechanisms by which saturated fatty acids induce depression from the four aspects mentioned above.

Adjuvant and neoadjuvant therapy are the important therapeutic methods for rectal cancer.Neoadjuvant concurrent chemoradiotherapy and postoperative adjuvant chemotherapy play a crutial role in rectal cancer treatment.New chemotherapy drugs and targeted therapy drugs could further improve the therapeutic effect of rectal cancer.

ObjectiveTo evaluate the changes of hepatic blood perfusion in cirrhotic patients undergoing pericardial devascularization (PCDV).MethodsHepatic artery and portal vein perfusion of 22 pre- and post- PCDV cirrhotic patients were evaluated with rheohepatogram(RHG) and ultrasonography (USG).ResultsCompared with normal control, the hepatic artery, portal vein effective perfusion and total hepatic perfusion decreased on RHG 〔(0.053?0.011) vs. (0.031?0.009),(0.033?0.011) vs. (0.018?0.008),〔(7.7?3.0) vs. (3.5?1.7), all P

ObjectiveTo observe the effects of free fatty aids (FFAs) on the apoptosis and migration of human breast cancer cells ( MDA-MB-231 ).MethodsBreast cancer cells were exposed to oleic acid (OA) and palmitic acid (PA) with different concentrations (50,200,and 500 umol/L).Quantity RT-PCR was conducted to detect mRNA expression of PTEN,and Western blot to detect protein expression of PTEN and Bcl-2.Cell apoptosis was measured with TUNEL method,and migration measured with transwell method.ResultsThe mRNA and protein expressions of PTEN in MDA-MB-231 cells were down-regulated after OA stimulation,but up-regulated after PA stimulation ( all P ＜ 0.05 ).The protein expression of Bcl-2 increased after OA stimulation and decreased after PA stimulation ( both P ＜ 0.05 ).PA increased the apoptosis,and both OA and PA enhanced the invasion of MDA-MB-231 cells.ConclusionsPA may promote apoptosis of MDA-MB-231 cells through changing the expression of the tumor suppressor PTEN,but also increases the invasion of the cancer cells.The invasion of cancer cells could be enhanced by OA stimulation as well.

Background and purpose:Pancreatic cancer is one of the most deadly human malignant neoplasms. Resistance to chemotherapeutic drugs is a major reason responsible for poor prognosis in the treatment of pancreatic cancer patients. MicroRNA (miRNA, miR) is a family of small non-coding RNA molecules, dysregulated miRNA is associated with various tumor biological function. miR-33a has been widely reported as a metabolism-related miRNA, while its relationship with drug resistance has little understand. This study was focused on the effect of miR-33a on gemcitabine chemoresistance in pancreatic cancer to bring the novel theoretical basis to chemotherapy for pancreatic cancer.Methods:In situ hybridization and Real-time PCR were used to analyze the miR-33a expressions in pancreatic cancer tissue sample and cell lines, respectively. Cell counting kit 8 (CCK-8) assay was used to calculate the IC50 value of different pancreatic cancer cells.Results:miR-33a was down-regulated in pancreatic cancer tissue and cell lines compared with para-cancerous tissues and normal HEK293T cells. Moreover, miR-33a over expression not only could enhance the chemosensitivity to gemcitabine in pancreatic cancer cells, but also rescue the gemcitabine resistance in pancreatic cancer cells.Conclusion:Down regulation of miR-33a in pancreatic cancer decreases the chemosensitivity to gemcitabine, resulting in development of acquired gemcitabine chemoresistance. It provides the theoretical basis to develop a new molecular targeted drug to combine with chemotherapy for pancreatic cancer.
