Objective To observe the therapeutic effect of abdominal kneading massage in treating chronic superficial gastritis. Methods Forty-six cases of chronic superficial gastritis were randomly divided into test group and control group, 23 cases in each group. The patients of the test group were treated by the abdominal kneading massage, once a day, 7 times for a course of treatment, and the treatment lasted 2 courses. The patients of the control group took the western medicine Domperidone tablets orally, 10 mg each time, 3 times a day, for 2 continuous weeks. After treatment, we compared the clinical efficacy on syndromes and gastroscopy detection results in both groups. Results ( 1) After treatment, the scores of syndromes were decreased in both groups ( P<0.01 compared with those before treatment) , and the decrease was more obvious in the test group ( P<0.05 compared with the control group). ( 2) The total efficiency of test group was 91.30%, and that of the control group was 60.87%, the difference being significant ( P<0.01). ( 3) The results of gastroscopy showed that the relief of the gastritis lesions of the test group was significantly better than that in the control group, and the difference was significant ( P < 0.01). Conclusion Abdominal kneading massage can effectively relieve the symptom and gastric mucosa inflammatory manifestations of the chronic superficial gastritis patients, and this treatment can be recommended in clinical application.

BACKGROUND:Chinese medicine therapy is effective for patients with mild-to-moderate lumbar spinal stenosis and also has a better long-term effect than surgical patients, which can enhance perioperative efficacy and prevent spinal restenosis. OBJECTIVE:To evaluate the clinical efficacy of “Tongmai songjin yigu” massage therapy on lumbar spinal stenosis. METHODS:Eighty-four patients with degenerative lumbar spinal stenosis were randomly and equaly divided into treatment group and control group. Treatment group were treated with “Tongmai songjin yigu” massage therapy; patients in the control group were treated according to the guidelines for diagnosis and treatment of common disease in orthopedics and traumatology promulgated by China Association of Chinese Medicine, once a day, continuous for 2 weeks. RESULTS AND CONCLUSION:After treatment, the visual analog scale score in the treatment group was improved significantly (P < 0.05), and there was a significant difference in the Japanese Orthopaedic Association Scores on subjective symptom and daily life between the treatment and control groups (P < 0.05). The effective rate of the treatment group was higher than that of the control group (P< 0.05). These findings indicate that “Tongmai songjin yigu” massage therapy is better than traditional massage, but clinical large-sample studies are required.

Objective:To observe the structural and functional changes of each nucleus group in generalized anxiety disorder(GAD) rat models before and after the massage therapy, and to explore the central regulating mechanism of the massage therapy in GAD.Methods:60 Wistar male rats were randomly divided into blank group, model group and abdominal rubbing group, 20 rats for each group. GAD rat models were established by chronic emotional stress, and the models were evaluated by the elevated cross maze experiment. In the abdominal rubbing group, the GAD rats were treated with abdominal rubbing once a day for 10 min for 14 days. In the control group, the GAD rats were only bound to the experimental platform once a day for 10 min for 14 days. Horseradish peroxidase (HRP) retrograde tracking marker method was used to detect the changes of the structure of each nuclear cluster in the affective loop of the GAD rats in each group. The liquid-mass spectrometry quantitative analysis was used to determine the relative concentrations of N-acetyl aspartate (NAA), glutamic acid, choline and creatine in nuclear cluster of the GAD rats in each group.Results:Compared with the blank group, the HRP labeled cells in the rats of model group were less expressed and the activity of the emotional circuit in the brain was weak. The NAA/creatine ratio in the left hippocampal tissue of the rats in the model group was significantly increased than that of the blank group(0.94±0.08 vs 0.79±0.10, P<0.05), the glutamic acid/creatine ratio in the right hippocampal tissue was significantly decreased (0.95±0.10 vs 1.12±0.13, P<0.01), and the NAA/creatine andglutamic and acid/creatineratios in the left cortical tissue were all significantly decreased (1.04±0.05 vs 1.41±0.23, and 1.21±0.04 vs 1.57±0.11, all P<0.01). Compared with the model group, the hippocampal tissues of the GAD rats in the abdominal rubbing group had a large number of HRP aggregation and spread to the surrounding tissues, the NAA/creatine and glutamic acid/creatine ratios in the left hippocampal tissue of the abdominal rubbing group were significantly decreased (0.74±0.21 vs 0.94±0.09 and 0.92±0.20 vs 1.21±0.12, all P<0.01). The differences between the model group and the abdominal rubbing group in the ratio of glutamic acid/creatine in the right hippocampal tissue (1.01±0.23 vs 0.95±0.10), the ratio of NAA/creatine in the left cortical tissue (1.12±0.09 vs 1.04±0.05), and the ratio of glutamic acid/creatine in the left cortical tissue (1.22±0.12 vs 1.21±0.04) were not statistically significant ( P>0.05). Conclusions:Abdominal rubbing can effectively enhance the activity of affective loop and improve the relative concentration of neuron metabolites in hippocampal and cortical tissues in the affective loop, suggesting that the mechanism of GAD treatment by abdominal rubbing may be closely related to the structure and function of regulating affective loop.

Objective:To observe the effect of abdominal mechanical stimulation on rats with irritable bowel syndrome-Diarrehea (IBS-D), and to explore the possible mechanism of abdominal massage mechanical stimulation to improve IBS-D.Method:60 newborn Wistar rats were randomly divided into blank group, model group and abdominal massage group, 20 rats for each group. The IBS-D rat model was established by separating the mother rats and newborn rats. In the abdominal massage group, the IBS-D rats were treated with abdominal rubbing once a day for 14 days. In the model group, the IBS-D rats were only bound to the experimental platform once a day for 5 min for 14 days. The rats in blank group were not made model and with no intervention. The intestinal motility and visceral sensitivity of rats were measured by the time of glass bulb expulsion and the abdominal lift volume threshold. The pathological changes of rat colon tissue were observed by hematoxylin-eosin staining. The changes of mast cells in colon tissue were observed by toluidine blue staining. The ultramicrostructure of intestinal glial cells was observed by transmission electron microscope. The content of proinflammatory factors IL-6 and IL-1β in rat plasma was determined by ELISA.Results:Compared with the model group, mechanical stimulation of the abdominal massage can significantly prolong the discharge time of the glass beads [(2.5±0.2) min vs (1.6±0.2) min], increase the abdominal lift volume threshold of rats [(0.5±0.1) ml vs (0.4±0.1) ml], improve the pathological state of the colon tissue, and reduce the number of mast cells [(2.64±0.22) per field vs (5.61±0.12) per field], reduce the number of mitochondria in the intestinal glial cells and increase the density of heterochromatin, and can also reduce the secretion of proinflammatory factors IL-6 [(189.4±4.7) pg/ml vs (224.8±8.6) pg/ml] and IL-1β [(178.4±7.1) pg/ml vs (191.4±8.4) pg/ml], and the differences were statistically significant (all P<0.05). Conclusions:Mechanical stimulation of abdominal massage can increase the visceral sensitivity of IBS-D rats, regulate intestinal glial cells and reduce the secretion of proinflammatory factors. The mechanism may be related to the intestinal-brain axis.

ObjectiveTo study the potential quality marker （Q-marker） of Tinosporae Radix associated with efficacy of "relieving sore throat" based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS）， multivariate statistical analysis （MSA）， and network pharmacology. MethodUPLC-Q-TOF-MS was used to identify the main chemical components in 18 batches of Tinosporae Radix. On this basis， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were employed to screen out the main marker components that caused differences between groups. Moreover， network pharmacology technology was applied to predict the potential "sore throat-relieving" components， and the molecular docking between the common components resulting from MSA and network pharmacology and the core targets was carried out to verify the marker components. ResultA total of 17 compounds， including alkaloids， diterpenoid lactones， and sterols， were identified by UPLC-Q-TOF-MS. Five main differential components were found by MSA： Columbamine， jatrorrhizine， palmatine， menisperine， and columbin. Network pharmacology analysis yielded six compounds： tetrahydropalmatine， palmatine， menisperine， fibleucin， neoechinulin A， and columbin which were selected as potential "sore throat-relieving" components of Tinosporae Radix. They may relieve sore throat by acting on interleukin-6， epidermal growth factor receptor， prostaglandin G/H synthase 2， matrix metalloproteinase-9， proto-oncogene tyrosine-protein kinase Src and other targets， and regulating Hepatitis B， influenza A， human T-cell virus infection， human cytomegalovirus infection， coronavirus disease-2019， and other signaling pathways. The common active components in Tinosporae Radix resulting from MSA and network pharmacology analysis were palmatine， menisperine， and columbin， which had high binding affinity with six core targets and can be used as the Q-marker components of Tinosporae Radix in "relieving sore throat". ConclusionThis study predicts the "sore throat-relieving" Q-marker of Tinosporae Radix， which lays a basis for developing the quality standard of Tinosporae Radix based on the efficacy and improving the quality evaluation system of the medicinal.
