OBJECTIVE: To investigate the changes of neuropeptides content in a rat model of spleen-deficiency syndrome. METHODS: Rats were randomly divided into three groups: normal group, untreated group and treatment group. There were ten rats in each group. Spleen-deficiency syndrome was induced by intragastrically administration of rhubarb concentrate in rats of the untreated and treatment group. The rats in the treatment group were intragastrically administered with Sijunzi decoction, a traditional Chinese compound herbal medicine for strengthening spleen and supporting qi. Normal saline was intragastrically administered to the rats in the normal and untreated groups. The somatostatin (SS) and cholecystokinin-8 (CCK-8) content in hypothalamus and colons was detected by the method of radioimmunoassay and the D-xylose content in urine was also detected. RESULTS: The CCK-8 content in hypothalamus of the untreated group was higher than that of the normal group (P<0.05). SS and CCK-8 content in colons of the untreated group was higher than that of the normal group (P<0.05). The CCK-8 content in colons of the untreated group was lower than that of the treatment group (P<0.05). The excretion rate of D-xylose in the untreated group was lower than that of the normal group (P<0.05). CONCLUSION: The disorder of neuroendocrine regulation in rats with spleen-deficiency syndrome may be chiefly responsible for "spleen-deficency and dysfunction of spleen" in traditional Chinese medicine.

OBJECTIVE: To evaluate the effects of Jianpi Qinghua Recipe (JPQHR) on chronic renal failure with syndrome of dampness-heat due to spleen deficiency and its mechanism. METHODS: One hundred and six patients were randomly divided into two groups: control group (53 patients treated with routine therapy) and JPQHR-treated group (53 patients treated with routine therapy and JPQHR). RESULTS: Routine therapy combined with JPQHR could improve symptoms. The serum creatinine, blood urea nitrogen, triglyceride and low density lipoprotein decreased significantly in the JPQHR-treated group as compared with those in the control group (P<0.05), while the number of erythrocyte rosette-forming cells increased significantly in the JPQHR-treated group as compared with those in the control group (P<0.05). CONCLUSION: Routine therapy combined with JPQHR can significantly decrease blood lipid level and strengthen cellular immune system, so it can lower the urine protein in the early and middle stages of chronic renal failure and improve renal function.

OBJECTIVE: To observe the clinical efficacy of the combination of traditional Chinese medicine and western medicine in treating irritable bowel syndrome (IBS) and the result of intestinal flora regulation. Methods: Sixty IBS patients, 36 males and 24 females, were divided into two groups, with 30 patients in each group. Herbal formula of TongxieYaofang and clostridium butyricum (Cb) were used in the first group for four weeks, while only Cb was used for four weeks in the second group. We observed the changes of coliform group, enterococcus, lactobacillus, bifidobacterium after treatment. RESULTS: The effective rate of the Tongxie Yaofang and Cb treated group was significantly higher than that of the Cb treated group (P < 0.05). The numbers of bifidobacterium and lactobacillus increased, while the numbers of coliform group and enterococcus decreased after the treatment, and the changes of intestinal flora in the integrative medicine treated group were significantly greater than those in the Cb treated group. CONCLUSION: After treatment with the combination of traditional Chinese medicine and western medicine, the intestinal flora can be regulated to equilibrium state.

Objective To explore the effects of ingestion of purified drinking water from water treatment devices on health of rats. Methods Under the same feeding conditions, the Wistar rats were divided into different exposure groups exposed to different kinds of drinking water such as electrolytic ion water (alkaline water), reverse osmosis water, middle hollow fabric filtered water, copper-zinc ally (KDF) filtered water, municipal water and source water respectively. The changes of the indexes including organ coefficient, routine blood test, blood biochemistry and electrolyte were observed at the 3rd and the 6th month of the exposure. Results Higher levels of the count of white blood cells and neutrophil, and higher concentrations of seralbumin and total albumin in serum were observed in rats of tap water group compared with those in control group (P

Objective To study the protection and mechanism of co-administration of vitamin E with coenzyme Q10(CoQ10) to valproate-associated hepatotoxicity in infantal rats.Methods The rat models were established by oral administration of valproic acid(VPA) in ablactation(21 days) Wistar rats,at doses of 500 mg/(kg?d) during 30 days,other groups received the same amount of VPA with phemobarbitone(PB) and co-administration with vitamin E and CoQ10.The changes of liver cell morphology and the blood coagulation test,as well as the contents of succinic dehydrogenase(SDH),cytochrome oxidase(CCO),cytochrome,the levels of glutothione(GSH) and malondial dehyde(MDA) in rat liver mitochondria were detected by chromatometry,HPLC,Oil-Red-O staining and electron microscope,respectively.Results 1.Average content of cytochrome aa3 in liver mitochondria of infantal rats were reduced by 58.80% and(61.80%) because of administration of VPA and VPA added with PB.The protection against the loss of cytochrome aa3 by coadministration of VitE and CoQ10 was obvious.As for activities of SDH and CCO,which affected by VPA and VPA added with PB in rats,were significantly lowered compared with control group(P

Objective To evaluate sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia.Methods Seventy ASA Ⅰ children were randomly divided into two groups,35 children in every group.Children in group S were appliedsevoflurane inhalation[the minimum alveolar concentration(MAC)of sevoflurane was 1.0-1.5],children in group PK were applied ketamine inhalation and total venous anesthesia of propofol[80μg/(kg·min)]with ketamine[20μg/(kg·min)].Compared the time of anesthesia induction,tracheal catheter extubation,anesthesia recovery between the two groups.The mean arterial pressure(MAP),heart rate,pulse oxygen saturation(SpO_2)during anesthesia were compared.During 2 days after operation,the adverse effects such as nausea and vomit,lower grade of sleep quality were also compared.Results Compared with group PK,the time of anesthesia induction,tracheal catheter extubation and anesthesia recovery in group S were shorter (P<0.05),the incidence of emergence agitation in group S was higher(20.0%,7/35 vs 2.9%,1/35)(P<0.05).But nausea(17.1%,6/35),vomit(31.4%,11/35)and lower grade of sleep quality(54.3%,19/35)were higher in group PK than those in groups(all 2.9%,1/35)at 1 day after operation(P<0.05).The incidence of lower grade of sleep quality at2 days after operation in group PK(14.3%,5/35)was higher than that in group S(0)(P<0.05).Cardiovascular effects of children,such as MAP and heart rate during the period of tracheal catheter extubation in group S was higher than that in group PK.Conclusion Sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia still has some disadvantages,the anesthesia technology is selected by anesthesia method and medicine combination.

Objective It is the first time that co -word analysis method was used throughout this study,which was based on all the Chinese research papers on childhood epilepsy published during the last two years.This study aimed to understand the current research status and progress in this field in China,and try to formulate the foundations for further study.Methods All the papers in database of Chinese National Knowledge Infrastructure,VIP database, Wanfang as well as PubMed were retrieved by using childrenand epilepsyas keywords.Publication date range was set from January 201 4 to June 201 5 and qualified papers were included in the research.Excel,Ucinet 6.0 and Net-draw software were used to analyze of the relationship between different key words and to generate diagrammatic repre-sentation.Results A total of 698 articles were identified and 41 high -frequently used keywords were extracted. Within the network planning of co -word relationship of high -frequency keywords,pediatric epilepsy was in the core rank,antiepileptic drugs,electroencephalogram,infantile spasm and treatment were hot topic issues.Pediatric epilepsy and electroencephalogram kept close relationships,so were pediatric epilepsy and antiepileptic drugs.Research status of Chinese childhood epilepsy was successfully represented and the possible future research was predicted through co -word analysis of these high -frequently used keywords.Conclusions At present,studies on childhood epilepsy are mostly focused on electroencephalogram,drug therapy,cognitive function,refractory epilepsy,pathogenesis as well as in-fantile spasms,but further research is needed to investigate the rehabilitation,comorbidity and immunity.

AIM:To investigate the influence and mechanisms of human pancreatic cancer tumor microenvironments on T-cell immunoglobulin mucin-3 (TIM-3) expression and function of dendritic cells (DCs).METHODS:Tumor-infiltrating dendritic cells (TIDC) and para-carcinoma tissue DCs were isolated by Ficoll-Hypaque density centrifugation from trypsinized pancreatic carcinoma tissues, and the peripheral blood mononuclear cells were isolated from pancre-atic cancer patients or healthy people.The expression of TIM-3 on DCs was detected by flow cytometry.DCs isolated from healthy people peripheral blood mononuclear cells were induced by rhGM-CSF and IL-4.The expression of TIM-3 in the DCs treated with the culture supernatants of Capan-2, SW1990 and Panc-1 pancreatic cancer cells or human skin fibroblast (Hs27) cells for 48 h, and in the DCs treated with supernatants of Capan-2 cells, anti-VEGF-R2, anti-IL-10 and EP2 re-ceptor blocking peptide were evaluated by flow cytometry.The releases of IFN-βand IL-12 in the culture supernatants of DCs pretreated with monoclonal antibody ( mAb) to TIM-3 or DNase+RNase, followed by stimulation with apoptotic Ca-pan-2 cells, were detected by ELISA.RESULTS:DCs in tumor microenvironments had higher expression of TIM-3 than the DCs from para-carcinoma tissues and pancreatic cancer patient or healthy people peripheral blood ( P<0.01 ) .TIM-3 expression in the DCs treated with the culture supernatants of Capan-2, SW1990 and Panc-1 pancreatic cancer cells for 48 h was much higher than that in Hs27 cells (P<0.05).Treatment with a combination of anti-VEGF-R2, anti-IL-10 and EP2 receptor blocking peptide largely diminished the upregulation of TIM-3 on the DCs mediated by Capan-2 cell superna-tants (P<0.05).The concentrations of IFN-βand IL-12 in the DCs with high expression level of TIM-3 were lower than those in the DCs with low TIM-3 expression level.Treatment with mAb to TIM-3 resulted in much more IFN-βand IL-12 releases (P<0.01), but DNase+RNase made this effect disappear.CONCLUSION:TIM-3 serves as a negative regula-tor of DCs innate immune responses in the pancreatic cancer microenvironments.The secretion of soluble factors to tumor microenvironment by pancreatic cancer cells, including IL-10, VEGF and PGE2 , may contribute to the regulation of TIM-3 expression.

Aim To study the protective effect of tetra-hydroxystilbeneglucoside ( TSG ) on cardiac injury and the mechanism involved in silent mating type informa-tion regulation 2 homolog 1 ( SIRT1 ) and adenosine monophosphate-activated protein kinase( AMPK) in the diabetic rats. Methods Type 2 diabetic rats were sac-rificed after administration with TSG for 8 weeks. Blood glucose, blood lipids, liverfunction,creatine ki-nase ( CK ) , lactate dehydrogenase ( LDH ) as well as myocardial nonesterified fatty acids( NEFA) were deter-mined by using biochemical test. The concentration of myocardial fatty acid transport proteins ( FATPs ) and-fatty acid β-oxidase ( FA-β-oxidase ) , and the levels of tumor necrosis factor alpha ( TNF-α) , interleukin -6 ( IL-6 ) , interleukin-1β( IL-1β) in serum were also measured by ELISA method and radio immunoassay re-spectively. The protein expressions of TNF-α, IL-6, IL-1β, SIRT1 and AMPK were detected by Western blot. Results Treatment of TSG reduced the contentof blood lipids, NEFA and collagen without affecting the content of blood glucose and insulin. The levels of TNF-α, IL-6 and IL-1βin serum as well as the protein expressions of TNF-α, IL-6 and IL-1β of cardia were also inhibited by administration with TSG. Treatment of TSG caused a significantly increased concentration of myocaidial FATPs and FA-β-oxidase, and dramatically restored the decreased protein expressions of SIRT1 and pAMPK in diabetic rats. Conclusion The protec-tive mechanisms of TSG against diabetic rats are in-volved in the alleviation of inflammatory mediator injury and improving energy metabolism.
