[Post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy on post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation. METHODS: Sixty patients with post-stroke dysphagia were randomly divided into an observation group and a control group, with 30 cases in each group. The neuromuscular electrical stimulation was adopted in the control group. Besides the treatment as the control group, in the observation group, the four-step acupuncture therapy for opening orifices and benefiting throat was supplemented. Step 1: the three areas of scalp acupuncture on the affected side were stimulated. Step 2: pricking method was operated on the posterior pharyngeal wall. Step 3: bleeding technique was operated at Jinjin (EX-HN 12) and Yuye (EX-HN 13). Step 4: deep insertion of needle was operated at three-pharynx points. The needles were retained for 30 min at the three areas of scalp acupuncture and the three-pharynx points. The intervention of each group was delivered once daily, 6 times a week, at the interval of 1 day. One course of treatment was 1 week and 4 successive courses were required. The rating of Kubota water swallow test, the score of standardized swallowing assessment (SSA) and the rating of Rosenbek penetration- aspiration scale (PAS) were observed before and after treatment in patients of the two groups. The incidence of clinical complications and clinical efficacy were compared between the two groups. RESULTS: Compared with those before treatment, the rating of Kubota water swallow test, the scores of SSA and the rating of PAS of patients in the two groups were decreased after treatment (P<0.01), and the values of the observation group were lower than those of the control group after treatment (P<0.05). The incidence of clinical complications in the observation group was 13.3% (4/30), lower than 36.7% (11/30) in the control group (P<0.05). The total effective rate in the observation group was 93.3% (28/30), which was better than 70.0% (21/30) in the control group (P<0.05). CONCLUSION: The four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation can improve the swallowing function of patients with post-stroke dysphagia and reduce the incidence of clinical complications.

Berberine is a potential alternative for metformin with good regulatory effect on lipids in treating metabolic diseases.

Metformin (MTF) and berberine (BBR) share several therapeutic benefits in treating metabolic-related disorders. However, as the two agents have very different chemical structure and bioavailability in oral route, the goal of this study is to learn their characteristics in treating metabolic disorders. The therapeutic efficacy of BBR and MTF was systemically investigated in the high fat diet feeding hamsters and/or ApoE(-/-) mice; in parallel, gut microbiota related mechanisms were studied for both agents. We discovered that, although both two drugs had almost identical effects on reducing fatty liver, inflammation and atherosclerosis, BBR appeared to be superior over MTF in alleviating hyperlipidemia and obesity, but MTF was more effective than BBR for the control of blood glucose. Association analysis revealed that the modulation of intestinal microenvironment played a crucial role in the pharmacodynamics of both drugs, in which their respective superiority on the regulation of gut microbiota composition and intestinal bile acids might contribute to their own merits on lowering glucose or lipids. This study shows that BBR may be a good alternative for MTF in treating diabetic patients, especially for those complicated with dyslipidemia and obesity.

Liver-target nanotechnology facilitates berberine to ameliorate cardio-metabolic diseases.

Cardiovascular and metabolic disease (CMD) remains a main cause of premature death worldwide. Berberine (BBR), a lipid-lowering botanic compound with diversified potency against metabolic disorders, is a promising candidate for ameliorating CMD. The liver is the target of BBR so that liver-site accumulation could be important for fulfilling its therapeutic effect. In this study a rational designed micelle (CTA-Mic) consisting of α-tocopheryl hydrophobic core and on-site detachable polyethylene glycol-thiol shell is developed for effective liver deposition of BBR. The bio-distribution analysis proves that the accumulation of BBR in liver is increased by 248.8% assisted by micelles. Up-regulation of a range of energy-related genes is detectable in the HepG2 cells and in vivo. In the high fat diet-fed mice, BBR-CTA-Mic intervention remarkably improves metabolic profiles and reduces the formation of aortic arch plaque. Our results provide proof-of-concept for a liver-targeting strategy to ameliorate CMD using natural medicines facilitated by Nano-technology.

[Study of huchang qingfei pellets on immune function in rats infected with Mycoplasma pneumoniae].

OBJECTIVE: To study the effects and mechanism of Huchang Qingfei pellets on immune function in rats infected with mycoplasma pneumoniae. METHOD: A rat model of mycoplasmal pneumonia (MP) was developed in repeated intranasal infectious routes and then the humoral and cellular immunocompetences were detected by radioimmunoassay, immune-turbidimetry and flow cytometry. RESULT: The levels of serum IgG,IgM and IL-2, IL-6 were enhinced obviously, the complement C3 and TNF-alpha were decreased and the ratio of CD4+ /CD8+ was improved significantly in the Huchang groups as compared with MP model group. CONCLUSION: Huchang Qingfei pellets can reinforce immune function via preventing both cellular and humoral immunity from depression in the rats with MP.

[Effect of Huchang Qingfei concentrated pellets on E-cadherin expression in lung tissue of mice infected with Mycoplasma pneumoniae].

OBJECTIVE: To investigate the effects of Huchang Qingfei concentrated pellets on the expression of E-cadherin (E-cd) in the lung tissue from mice infected with Mycoplasma pneumoniae (MP). METHOD: A mice model of Mycoplasmal pneumonia (MPP) was developed by repeatedly intranasal infectious route. Transmission electronic microscope (TEM) and immunohistochemistry stain were performed to observe the pathological changes and expression of E-cd in lung tissues. RESULT: Under TEM it was found that the cellular membrane was ruptured, mitochondria was denatured, crista was broken in the pulmonary cells of the model group; the all above parameters in Huchang medicated group were improved obviously. The immunohistochemistry test showed that strong positive brown stain of E-cd expression was found in the pulmonary epithelial cell membrane and bronchial periphery in the model group, however, in the medicated group, the E-cd expression level in the cellular membrane was decreased and the expression ratio was dropped significantly as compared with the model controls. CONCLUSION: Huchang Qingfei concentrated pellets can inhibit the overexpression of E-cd in the lung tissue of mice with MP-infection, which may be helpful for prevention and treatment of pulmonary injury caused by MPP.
