OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

OBJECTIVETo observe analgesic effect of electroacupuncture ( EA) on rats with chronic inflammatory pain and its regulatory mechanism on ispilateral dorsal root ganglion (DRG) and spinal dorsal horn (SDH) Mas-related G protein-coupled C receptor (MrgprC).

METHODSTotally 40 healthy male SD rats were divided into 4 groups according to random number table, i.e., the normal (N) group, the model (M) group, the acupuncture (Acu) group, the EA group, 10 rats in each group. The model of chronic inflammatory pain was established by subcutaneous injecting 0. 1 mL complete Freund's adjuvant (CFA) into right hind paw. Paw withdrawal thresholds (PWTs) were measured before modeling, at day 1, 3, 5, 7, and after CFA injection, respectively. Expression levels of MrgprC in ispilateral DRG and SDH were detected by Western blot. The content of bovine adrenal medulla 22 (BAM22) in SDH was detected by immunohistochemical assay.

RESULTSCompared with N group at each time point, PWTs significantly decreased in M group (P <0. 01). Compared with M group, PWTs significantly increased at day 5 of EA and after EA in EA group (P < 0.05, P < 0.01). Compared with Acu group at each time point, post-EA PWTs significantly increased in the EA group (P < 0.05). Compared with N group, expression of MrgprC in ispilateral DRG and ratio of BAM22 positive cells in ispilateral SDH increased in M group (P < 0.01). Compared with M group, expression of MrgprC in ispilateral DRG and ratio of BAM22 positive cells in ispilateral SDH increased in the EA group (P < 0.05).

CONCLUSIONEA had favorable analgesic effect on chronic inflammatory pain induced by CFA, and its mechanism might be possibly associated with up-regulating MrgprC expression in ispilateral DRG and BAM22 content in ispilateral SDH.

OBJECTIVE Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disease with a high morbidity around 1/1000-1/400, characterized by progressive enlargement of fluid-filled cysts derived from renal tubular epithelial cells. Massive cysts gradually compress renal parenchyma destroying normal renal structures and compromising renal functions. Unfortunately, it will cause end-stage renal disease in most of the patients but without effective therapy now, who have to live on hemodialysis or kidney transplantation. Based on this present situation, it is of great significance to find early intervention to inhibit renal cyst development. The projective of this study was to investigate whether Ganoderma triterpenes (GT) can inhibit renal cyst development and study the related mechanism. METHODS and RESULTS First, we used MDCK cyst model, cultivated MDCK cells in vitro to form fluid-filled cysts surrounded by monolayer cells. GT inhibited MDCK cyst formation significantly, and inhibited cyst enlargement dose-dependently proving GT cyst inhibition in vitro. Then we used an embryonic kidney cyst model, wile-type mice kidneys were taken out on embryonic day 13.5 to form renal cysts stimulated with 8-Br-cAMP. GT inhibited embryonic kidney cyst development significantly in a dose-dependent and reversible manner proving GT cyst inhibition at organ level. Furthermore, we used two ADPKD mouse models with severe cystic kidney disease phenotypes. GT dramatically inhibited renal cyst development, decreased ADPKD mouse kidney volume and the cyst index inside proving GT cyst inhibition in vivo. By Western blot, we proved GT down-regulated Ras/MAPK signal pathway without detectable effect on mTOR signal pathway both in MDCK cells and two ADPKD mouse kidneys. CONCLUSION GT retard renal cyst development both in vitro and in vivo significantly. The related mechanisms were involved in GT promoting renal tubular epithelial cell differentiation, down-regulating intracellular cAMP level and Ras/MAPK signal pathway.

The pH of gastric acid after treatment was significantly higer than that before treatment ( P <0.05 ) .The pH of gastric acid was significantly different 6 hours after treatment between the two groups ( P<0.05 ) .No obvious adverse drug reaction was observed in the two groups in the period of treatment .Conclusion Almagate combined with lansoprazole is effective and safe in the treatment of stress ulcer patients with heavy craniocerebral injury.

Objective The neuronal ceroid lipofuscinosis (CLN are a group of severe lysosomal storage diseases.The patients present with clinically and genetically heterogeneous neurodegenerative disorders.This study aims to investigate the clinical characteristics and the gene mutations of a rare Chinese family with 3 siblings affected by CLN7.Methods The proband,a 5-year-old girl,visited us because of intermittently seizures and mental retardation for 2 years and a half in December,2015.Clinical investigation,brain magnetic resonance imaging(MRI),biochemical and the gene analysis were performed for the etiological study.Results The proband had seizures at the age of 2 and a half years,with the progressive motor deterioration,speech disturbance,mental regression and vision loss.Her brain MRI showed diffusive cerebral atrophy.The blood aminoacids,acylcarnitine and urine organic acid profiles were normal.Lysosomal palmitoyl protein thioesterase and tripeptidyl peptidase activities of peripheral leukocytes were normal.A compound heterozygous mutation of c.1351-1G ＞ A and c.300T ＞ G was detected on her MFSD8 gene,supporting the diagnosis of CLN7.Both of the 2 mutations were novel.Each of her parents carried one of the mutations.Two brothers of the proband had similar clinical process.Her elder brother died at the age of 7 due to severe encephalopathy of unknown etiology.The younger brother showed dyskinesia from the age of 2 years and seizures from the age of 4 years.A compound heterozygous mutation on MFSD8 gene,c.1351-1G ＞ A and c.300T ＞ G,was found from the younger brother,as same as the proband.Conclusions CLN7 is a rare disorder of CLN.In this study,the diagnosis of the 3 siblings with similar clinical process were much delayed.Gene analysis was key for the diagnosis.Two novel mutations were found on MFSD8 of the family.There is still no effective treatment for neurol ceroid lipofuscinosis.The prognosis is poor.Based on the mutation diagnosis,prenatal diagnosis for the next sibling is possible to the prevention of the disease.

Two-dimensional polyacryiamide gel electrophoresis (2D-PAGE) and matrixassisted laser desorption/ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF-MS), incorporated with online database searching, were performed to investigate differential proteins of breast cancer and adjacent normal breast tissues. Considering that serum albumin is abundantly presented in normal control samples, 15 differential spots detected in 11 out of 12 (91.7%) breast cancer samples were identified by online SIENA-2DPAGE database searching and MALDI-TOF/TOF-MS analysis. The results indicate that pathological changes of breast cancer are concerned with augmentation of substance metabolism, promotion of proteolytic activity, decline of activity of some inhibitors of enzymes, and so on. Some important proteins involved in the pathological process of breast cancer with changed expression may be useful biomarkers, such as alpha-1-antitrypsin, EF1-beta, cathepsin D, TCTP, SMT3A, RPS12, and PSMA1, among which SMT3A,RPS12, and PSMA1 were first reported for breast cancer in this study.

OBJECTIVETo summarize lessons learned from an outbreak of severe acute respiratory syndrome (SARS) in China during the spring of 2004.

METHODSData of SARS cases were officially reported by Beijing Municipal Center for Disease Control and Prevention (BCDC) and Anhui Provincial Center for Disease Control and Prevention (APCDC) and results of epidemiological investigations were collected and analyzed.

RESULTSThree generations of 11 cases of SARS were identified during the outbreak. Initial two cases were most likely to be infected in Diarrhea Virus Laboratory of National Institute of Virology, China Centers for Disease Control and Prevention and main mode of transmission was direct contact with SARS patients. Delay in detecting initial case resulted in spread of the illness at hospitals and communities with two generations of secondary cases.

CONCLUSIONSSARS outbreak in 2004 has yielded following lessons for public health globally. (1) Lab bio-safety programs should be made and should be strictly abided by. Studies in highly pathogenic viruses such as SARS coronavirus should be utmost cautious. (2) Management systems of occupational exposure to virus and disease surveillance need to be strengthened to take all risk factors into account so as to detect potential patients with infectious disease as early as possible.

AIMTo investigate the protective effect of monosialoganglioside (GM1) on injury induced by oxygen glucose deprivation/reperfusion (OGD/Rep) in rat hippocampal slices.

METHODSThe protective effects of GM1 on hippocampal slices after OGD/Rep were observed by detecting the light transmittance (LT) changes of rat hippocampal slices and 2, 3, 5-triphenyltetrazolium chloride (TTC) staining of rat hippocampal slices.

RESULTS(1) In four groups treated with 0 (control), 0.1, 1.0, 10 micromol/L GM1, the peak of light transmittance (LT) in the slices treated with 1.0 micromol/L GM1 was significantly lower than that of the control and the group treated with 0.10 micromol/L GM1 (P < 0.01, ANOVA), while the peak of LT in the slices treated with 10.0 micromol/L GM1 was significantly lower than that of the other groups (P < 0.01, ANOVA). The time to reach the peak of LT in four groups was significantly different from each other (P < 0.05, Kruskal-Wallis test). The time to reach the peak of LT in the group treated with 1 micromol/L GM1 was the significantly longer than that in the control (P < 0.01, Mann-Whitney U test). (2) There was characteristic dose-response relationship between GM1 and TTC staining of rat hippocampal slices. In the five groups, treated with 0 (control), 0.01, 0.1, 1.0, 10 micromol/L GM1 respectively, TTC staining in the group treated with 1 micromol/L GM1 was the deepest (P < 0.05 vs. control, 0.01 and 0.1 micromol/L GM1 group, ANOVA), and the next was in the group treated with 10 micromol/L GM1 (P < 0.05 vs. control and 0.01 micromol/L GM1 group, ANOVA).

CONCLUSIONGM1 could protect injury induced by OGD/Rep in rat hippocampal slices effectively in vitro.
