Ginger-partitioned moxibustion plus pediatric massage for treating infantile diarrhea due to spleen deficiency: a randomized controlled clinical trial / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of ginger-partitioned moxibustion plus pediatric massage (tuina) in treating infantile diarrhea due to spleen deficiency. Methods: Ninety infants were randomly divided into a massage plus moxibustion group, a massage group and a drug group by the random number table method, with 30 cases in each group. The intervention was conducted for two consecutive courses. The infants in the massage plus moxibustion group were treated with pediatric massage and ginger-partitioned moxibustion at Shenque (CV 8). The infants in the massage group were treated with pediatric massage alone, while those in the drug group were treated with smecta. The primary and secondary symptom scales were assessed before and after treatment and at the follow-ups, and the total effective rate was evaluated after treatment. Results: The total effective rate in the massage plus moxibustion group was significantly different from that in the massage group and drug group (both P<0.05). After treatment, the scores of primary and secondary symptoms decreased in all three groups, with statistically significant intra-group differences (all P<0.05); the scores of primary symptoms were significantly different between the massage plus moxibustion group and the drug group (P<0.05); the scores of secondary symptoms in the massage plus moxibustion group and the massage group were significantly different from that in the drug group (both P<0.05). The differences in the time to recover normal bowel movement frequency among the three groups were not statistically significant (P>0.05). Conclusion: Ginger-partitioned moxibustion plus pediatric massage compared with pediatric massage or smecta monotherapy shows superior clinical efficacy in treating infantile diarrhea due to spleen deficiency, and has the advantages of appetite improvement, physique strengthening and short course.

Objective:To explore the correlation between the efficacy of <italic>Usnea diffracta</italic> in treating atherosclerosis （AS） and the altered microbial flora in rat ileum based on the interior-exterior relationship between heart and small intestine in traditional Chinese medicine （TCM）. Method:Forty-eight SD rats were randomized into a normal group （<italic>n</italic>=8） and a modeling group （<italic>n</italic>=40）. The AS model was established with high-fat diet combined with intraperitoneal injection of vitamin D₃. The successfully modeled rats were further randomly divided into the model group， positive control （simvastatin， 4 mg·kg^-1） group， and low- （0.7 g·kg^-1）， medium- （1.4 g·kg^-1）， and high-dose （2.8 g·kg^-1） <italic>U. diffracta</italic> ethanol extract groups， with eight rats in each group. After four weeks of intervention， the blood， aorta， ileum， and ileum content of rats in each group were collected. The levels of serum lipopolysaccharide （LPS）， tumor necrosis factor-<italic>α </italic>（TNF-<italic>α</italic>） and interleukin 6 （IL-6） were measured by enzyme-linked immunosorbent assay （ELISA）， and the pathological changes in rat thoracic aorta was detected by hematoxylin-eosin （HE） staining. Western blot was conducted to determine the protein expression levels of tight junction protein zonula occluden （ZO-1） and Occludin in rat ileum， and the high-throughput 16S rRNA sequencing technology was employed to detect changes in microbial diversity and abundance in rat ileum of each group. Result:Compared with the normal group， the model group exhibited obvious aortic plaque deposition， increased LPS， TNF-<italic>α</italic>， and IL-6 levels （<italic>P</italic><0.01）， but decreased ZO-1 and Occludin protein expression （<italic>P</italic><0.01）. The comparison with the model group revealed that <italic>U. diffracta</italic> significantly ameliorated the aortic plaque deposition of model rats， lowered serum LPS， TNF-<italic>α</italic>， and IL-6 levels （<italic>P</italic><0.05， <italic>P</italic><0.01）， and up-regulated ZO-1 and Occludin protein expression （<italic>P</italic><0.05， <italic>P</italic><0.01）. The abundance of Proteobacteria and Bacteroidetes in the model group changed significantly in contrast to that in the normal group， and the Bacteroidetes/Firmicutes（B/F） value declined （<italic>P</italic><0.05）. Alpha and Beta diversity analysis indicated higher total number of intestinal flora species in the model group， but lower richness and uneven distribution （<italic>P</italic><0.05， <italic>P</italic><0.01）， with a large number of pathogenic bacteria enriched. The ethanol extract of <italic>U. diffracta</italic> significantly increased the B/F value， corrected the structural disorder of microbial flora in ileum， reduced pathogenic bacteria， and increased the relative abundance of probiotics. Conclusion:<italic>U. diffracta</italic> exerts the therapeutic effect against AS possibly by improving the intestinal microbial communities， strengthening the intestinal mucosal barrier function， and reducing the serum LPS and inflammatory factors.

wareness and knowledge of oral cancer among 1 483 residents in Beijing / 北京大学学报(医学版)

OBJECTIVE@#To investigate the oral cancer awareness, its related knowledge among residents in Beijing.@*METHODS@#A questionnaire survey was conducted among Beijing residents (non-medical related personnel) on the knowledge of oral cancer and its prevention and treatment.@*RESULTS@#A total of 1 483 questionnaires were completed, including 663 males (44.6%) and 820 females (55.3%), ranging from 15 to 91 years. Lung cancer was the most mentioned as heard of (94.3%), followed by liver cancer (92.5%) and gastric cancer (92.4%), while oral cancer was the least heard of (47.7%). Family account (P=0.015), residence (P=0.028), income (P=0.024), frequency of brushing teeth (P<0.001), frequency of mouth self-examination (P<0.001) and chew betel nut chewing (P=0.015) were significantly associated with oral cancer awareness. Most respondents learned about oral cancer from TV programs (24.3%), phone news (22.0%), WeChat (11.3%) and chatting with friends or people around (14.6%). Only 34.9% knew that smoking was a risk factor of oral cancer, and this knowledge was associated with age (P=0.011), education level (P=0.007), frequency of brushing teeth (P<0.001), and frequency of mouth self-examination (P=0.002). Only 23.5% knew that drinking was a risk factor of oral cancer, and this knowledge was associated with education level (P=0.002), residence (P=0.022), frequency of brushing teeth (P=0.009), and frequency of mouth self-examination (P=0.005). Only 35.1% knew that betel nut chewing was a risk factor for oral cancer, and this knowledge was associated with age (P=0.040), education level (P=0.002), family account (P=0.002), income (P=0.005), frequency of brushing teeth (P=0.001), frequency of mouth self-examination (P<0.001), and betel nut chewing (P=0.002). Only 35.7%, 21.6% and 16.9%, respectively, knew that long-term unhealed ulcers, white plaques and red plaques in the mouth were the early signs of oral cancer.@*CONCLUSION@#This survey demonstrates a general lack of public awareness and knowledge about signs and symptoms of oral cancer, and its risk factors and treatment. Some residents have not formed good oral hygiene habits. Specific measures should be taken to improve the public awareness of oral cancer and related knowledge about prevention and treatment, such as the use of various new media for the public to promote their oral health knowledge, in order to reduce the incidence of oral cancer, improve early attendance rates and the patients' survival rates.

Warm needling moxibustion versus electroacupuncture for simple obesity due to yang deficiency of the spleen and kidney: a controlled clinical trial / 针灸推拿医学（英文版）

Objective: To compare the therapeutic efficacy between warm needling moxibustion and electroacupuncture (EA) in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Methods: Seventy patients with simple obesity due to yang deficiency of the spleen and kidney were randomly divided into a warm needling moxibustion group and an EA group, with 35 subjects in each group. Same major acupoints were selected for the two groups, including Shuifen (CV 9), Guanyuan (CV 4), Daheng (SP 15), Shuidao (ST 28), Shousanli (LI 10), Zusanli (ST 36), Sanyinjiao (SP 6) and Taixi (KI 3). The warm needling moxibustion group received warm needling moxibustion, while the EA group received EA treatment. The interventions were performed once every other day, with 15 treatments as one course. The therapeutic efficacy, body weight and body mass index (BMI) were then observed and compared. Results: The total effective rate in the warm needling moxibustion group was 85.7％ versus 77.1％ in the EA group, and the between-group difference was statistically significant (P<0.05). The warm needling moxibustion was remarkably superior to the EA in weight loss and lowering BMI, both with statistical significance (P<0.05, P<0.01). At the three-month follow-up, the body weight and BMI further decreased in the warm needling moxibustion group (both P<0.05), and the levels were lower than those in the EA group (P<0.05, P<0.01). Conclusion: Warm needling moxibustion can produce reliable and consistent efficacy in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Compared with EA, warm needling moxibustion shows advantage in both short-term and long-term efficacies, and thus is worth promotion in clinical practice.

Digoxin inhibits migration and invasion of human gastric carcinoma MKN45 cells through down-regulation of AEG-1 / 生理学报

This study was designed to investigate the effect of digoxin on migration and invasion of human gastric carcinoma MKN45 cells and its possible mechanism. MKN45 cells were treated with different concentrations of digoxin for 24 h. The shRNA-AEG-1 plasmid was transfected into MKN45 cells via lipofectamine to block the expression of astrocyte elevated gene-1 (AEG-1). Western blot was used to analyze the protein levels of matrix metalloproteinase-9 (MMP-9), E-cadherin and AEG-1. The result showed that digoxin reduced the abilities of migration and invasion (P < 0.05), up-regulated the protein level of E-cadherin (P < 0.05), and down-regulated the protein levels of MMP-9 and AEG-1 (P < 0.05) in MKN45 cells in a dose-dependent manner. Compared with shControl group, shAGE-1 group showed inhibited cellular migration and invasion, higher expression level of E-cadherin, and lower expression levels of MMP-9 and AEG-1. These results suggest that digoxin suppresses the migration and invasion of human gastric carcinoma MKN45 cells in a dose-dependent manner through inhibiting the expression of AEG-1, and then resulting in the up-regulation of the protein expression of E-cadherin and the down-regulation of the protein expression of MMP-9.

Baicalin attenuates Aβ25-35 induced learning and memory disorders in mice and its possible mechanism / 中国药理学与毒理学杂志

OBJECTIVE To observe the effect of baicalin on Aβ25-35 induced learning and memory deficits and changes in autophagy-related genes in mice so as to explore the related mechanisms of Alzheimer disease (AD) treatment . METHODS C57 mice were administered with 3μL Aβ25-35 3 mmol·L-1 by intracerebroventricular injection to establish an AD model. Baicalin was given by intracerebroventricular injection at the dose of 25, 50 and 100 mg · kg-1 for 15 d, respectively. The total distance and the central grid residence time were measured in the open-field test. The escape latency and the time to reach the platform were monitored in the Morris water maze trial. The autophagic vacuoles in the hippocampus of the mice were observed by transmission electron microscopy before the protein expressions of microtu?bule-associated protein 1 light chain 3 (LC3) and Beclin1 in brain tissue were analyzed by Western blot?ting assay. RESULTS Intracerebroventricular injection of Aβ25-35 could reduce the total distance from (3984±321)cm to (2790±306)cm and extend central grid residence time from (3.6±1.2)s to (8.8±2.9)s in the open-field test. The escape latency of water maze also increased from (22.0 ± 1.9)s to (38.8 ± 2.2)s. Autophagic vacuoles or late autophagic vacuoles and increased Beclin1 and LC3 and protein level were observed in the hippocampus after Aβ25-35 injection. Intraperitoneal injection of Baicalin 50 and 100 mg · kg-1 for fifteen consecutive days extended the total distance in open-field test to (3705 ± 337)cm and (3968 ± 448)cm, respectively, while the central grid residence time was reduced to (5.6 ± 1.8)s and (3.9±1.5)s, respectively. The total time taken to reach the platform in water maze test was reduced to (28.6± 1.9)s, (22.9 ± 1.7)s. Mitochondrial swelling, vacuolar membrane structure or autophagic vacuoles were visible in the hippocampus. LC3 and Beclin1 protein expression was significantly up-regulated(P<0.01). CONCLUSION Baicalin shows protective effect against Aβ25-35 induced learning and memory deficits, and this effect may be related to the activation of autophagy in the mouse hippocampus.

Clinical application of modified electroconvulsive therapy in psychiatric inpatients / 新乡医学院学报

Objective To investigate the clinical application of modified electroconvulsive therapy (MECT),and provide the references for more standardized and rational use of MECT.Methods A retrospective study was performed by stratified random sampling method.The clinical data of 1 330 psychiatric inpatients from January 2006 to December 2015 in Henan Psychiatric Hospital were analyzed retrospectively,and the clinical application of MECT was investigated,including the proportion of psychiatric inpatients receiving MECT,the situation of combined use of MECT and antipsychotic drugs,and the routine examination results before and after MECT.Results The proportion of receiving MECT in schizophrenic patients was the highest,it is 11.36％ (81/713),the second was depressive episode (5.61％,12/214),followed by dissociative conversion disorder (5.56％,2/36),bipolar disorder (5.34％,7/131),organic mental disorder (3.23 ％,1/31) and other mental disorders (2.93％,6/205).There were significant differences in the distribution of various mental disorders between the non electroshock group and the electroshock group (x2 =21.728,P ＜ 0.05).The proportion of the patients without electric shock and the patients with single drug,two drugs,triple therapy or quadruple therapy was 0.92％,17.43 ％,56.88％,21.10％ and 3.67％,respectively.The proportion of the patients with two or more antipsychotic drugs was 81.65％ in the electroshock group.The antipsychotics were olanzapine (28.44％),clozapine (27.52％),quetiapine (26.61％) and risperidone (24.77 ％) according to the drugs used frequently in the electroshock group.The results of routine blood test were compared among the time points of before treatment,the 1st,2nd,3 rd week of MECT and 1 week after MECT in the shock group,which showed that there was significant difference in white blood cell count (F =2.570,P ＜ 0.05);but there was no significant difference in the levels of platelet,hemoglobin and red blood cell (P ＞ 0.05);the level of white blood cell returned to normal within two weeks in 93.33％ patients with increased white blood count.The myocardial enzymes and liver function tests were not perfect during the treatment of MECT and after treatment.There was no long-term systematic evaluation of cognitive function and quality of life in patients with electroconvulsive shock.Conclusions The probability of using MECT in the patients with schizophrenia is more than that in the patients with depression.MECT is used in combination with two or more antipsychotic drugs.MECT may cause a short increase in white blood cells,but the white blood cell level in most patients can recover to normal levels after symptomatic treatment.The clinical data for treatment and prognosis in patients with MECT are inadequate,so it is necessary to improve the medical record.

Upregulation of cystathionine β-synthetase in the arcuate nucleus produces pain hypersensitivity via PKC upregulation and GluN2B phosphorylation in rats with chronic pancreatitis / 生理学报

Hydrogen sulfide (HS) contributes to visceral hyperalgesia in primary sensory neurons, but its role in central nervous system remains largely unknown. This study was to investigate the roles and underlying mechanisms of HS and its endogenous synthesis enzymes in the arcuate nucleus (ARC) in rat pancreatic hyperalgesia. Chronic pancreatitis (CP) was induced in male adult Sprague-Dawley rats by intra-pancreatic ductal injection of trinitrobenzene sulfonic acid (TNBS). Abdominal hyperalgesia was assessed by referred somatic behaviors to mechanical stimulation of rat abdomen. Western blot analysis was performed to detect protein expression in the ARC. CP markedly upregulated cystathionine β-synthetase (CBS) expression but did not alter cystathionine-γ-lyase level in the ARC at 4 weeks after TNBS injection. Although the expression of total GluN2B was not altered, CP greatly enhanced the phosphorylation level of GluN2B in the ARC when compared with age- and sex-matched control rats. CP also significantly increased expression of protein kinase Cγ (PKCγ) in the ARC. Arcuate microinjection of O-(Carboxymethyl) hydroxylamine hemihydrochloride (AOAA, an inhibitor of CBS) significantly attenuated abdominal pain in CP rats in a dose-dependent manner and reversed the CP-induced upregulation of p-GluN2B and PKCγ in the ARC. Furthermore, the GluN2B inhibitor or specific PKC inhibitor chelerythrine significantly attenuated abdominal hyperalgesia in CP rats. The p-GluN2B expression was also suppressed by PKC inhibitor. Taken together, our results suggest that the upregulation of CBS in the ARC leads to an activation of GluN2B via PKCγ, which may play an important role in generation of pain hypersensitivity of CP.

Extraction, purification and identification of type II collagen from Agkistrodon acutus / 中国中药杂志

The object of the research was to extract, purify and identify the type II collagen of Agkistrodon acutus. Type II collagen of A. acutus was extracted by enzyme decomposition method, and purified by ion exchange column chromatography. It was characterized by SDS-PAGE gel electrophoresis, ultraviolet spectrophotometry, infrared absorption spectroscopy and mass spectroscopy. The results showed that the size of C II was about 130 kDa. It absorbed at 223 nm. IR spectrum obtained showed that the triple helical domains of amino-acid sequences were characterized by the repetition of triplets Gly-X-Y. The MS spectrum graphically stated that C II extracted from cow and A. acutus have the similar peptides. The C II of A. acutus was obtained by extraction and purification. Appraisal analysis by SDS-PAGE, UV, IR and MS, C II of A. acutus was consistent with the standard C II of cow. It was proved that the extracted protein was C II.

Study on intervention effect of Jieduquyuziyin prescription systemic lupus erythematosus by HPLC-Q-TOF/MS / 中国中药杂志

To establish a metabonomic method based on high performance liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-Q-TOF/MS), in order to study the changes in serum metabolites of systemic lupus erythematosus (SLE) mice after treatment of Jieduquyuziyin prescription, the pathogenesis of SLE and mechanism of drug action. The orthogonal partial least squares (OPLS) was applied for the pattern recognition of experimental data, finding a significant difference in the control group, the SLE model group, the Jieduquyuziyin prescription-treated group and the prednisone acetate-treated group. According to the OPLS load diagram, 12 differential metabolites, including traumatic acid, PAF, 12 (S)-HEPE, 15(S)-HETrE and Hepoxilin B3 were identified by using accurate mass combined with MS/MS data After treatment with Jieduquyuziyin prescription, the relative contents of PAF, 12 (S)-HETE were close to the level of the control group. According to the analysis on metabolic pathway, SLE could cause significant changes in unsaturated fatty acid and amino acid metabolism pathway, while Jieduquyuziyin prescription has a effect in regulating disorder of unsaturated fatty acid metabolism pathway.

Effect of prescriptions replenishing vital essence, tonifying Qi and activating blood on TNF-alpha, IL-1beta expressions in serum and submaxillary gland of NOD mice with Sjogren's syndrome / 中国中药杂志

<p><b>OBJECTIVE</b>To observe effect of prescriptions replenishing vital essence, tonifying Qi and activating blood on expression of tumor necrosis factor-alpha (TNF-alpha) and interleukin-IP (IL-1beta) in serum and submaxillary gland of non-obese diabetic (NOD) mice with Sjogren's syndrome.</p><p><b>METHOD</b>Thirty-two NOD mice were divided into four groups at random: the model group, the traditional Chinese medicine (TCM) group, the hydroxychloroquine group, the TCM and western medicine (WM) group, with 8 mice in each group. Eight Balb/C mice were taken as the normal normal control group. The TCM group was orally administered with 0.4 mL decoction replenishing vital essence, tonifying Qi and activating blood (100 g x kg(-1)) everyday; the hydroxychloroquine group were given 0.4 mL hydroxychloroquine (60 mg x kg(-1)) everyday; the TCM WM group were given 0.4 mL decoction, replenishing vital essence tonifying Qi and activating blood (50 g x kg(-1)) and hydroxychloroquine (60 mg x kg(-1)) everyday. Mice were sacrificed after eight weeks, and their arterial blood and tissues of submaxillary gland were collected. The levels of TNF-alpha, IL-1beta in serum were detected by ELISA. Expressions of TNF-alpha, IL-1beta protein in submaxillary gland were detected by immunohisto-chemistry.</p><p><b>RESULT</b>Compared with other groups, TNF-alpha, IL-1beta in serum and submaxillary gland in the model group were higher (P < 0.05). The normal group showed lower serum TNF-alpha level than other groups (P < 0.05), but without statistical significance compared with the TCM group. IL-1beta in serum in the TCM group and the TCM WM group were lower than that of the hydroxychloroquine group (P < 0.05), but without statistical significance compared with the normal group. TNF-alpha protein expression in the TCM group and the TCM WM group showed no significant difference compared with the normal group, whereas the TCM WM group were notably lower than that of the hydroxychloroquine group (P < 0.05). IL-1beta expression in the TCM WM group showed no significant difference compared with the normal group.</p><p><b>CONCLUSION</b>The decoction replenishing vital essence, tonifying Qi and activating blood can decrease the levels of TNF-alpha, IL-1beta in serum and submaxillary gland of NOD mice with Sjogren's syndrome. It may improve pathological damage of submaxillary gland by regulating Th1/Th2 cell factors, in order to achieve the therapeutic effect on SS.</p>
