RESUMO
Objective To explore the effects of different acupoints,different target organs,and different interventions on acupoint efficacy based on ACU&MOX-DATA platform;To illustrate and visualize whether the above factors have the characteristics of"specific effect"or"common effect"of acupoint efficacy.Methods The multi-source heterogeneous data were integrated from the original omics data and public omics data.After standardization,differential gene analysis,disease pathology network analysis,and enrichment analysis were performed using Batch Search and Stimulation Mode modules in ACU&MOX-DATA platform under the conditions of different acupoints,different target organs,and different interventions.Results Under the same disease state and the same intervention,there were differences in effects among different acupoints;under the same disease state,the same acupoint and intervention,the responses produced by different target organs were not completely consistent;under the same disease state and acupoint,there were differences in effects among different intervention measures.Conclusion Based on the analysis of ACU&MOX-DATA platform,it is preliminary clear that acupoints,target organs,and interventions are the key factors affecting acupoint efficacy.Meanwhile,the above results have indicated that there are specific or common regulatory characteristics of acupoint efficacy.Applying ACU&MOX-DATA platform to analyze and visualize the critical scientific problems in the field of acupuncture and moxibustion can provide references for deepening acupoint cognition,guiding clinical acupoint selection,and improving clinical efficacy.
RESUMO
Objective:To analyze the in vitro inhibitory effects of resveratrol on rabies virus. Methods:The challenge virus standard (CVS)-11 strain of rabies virus and BHK-21 cells were used to establish the infection model. In vitro inhibitory effects of resveratrol on rabies virus were analyzed at different stages of infection by direct immunofluorescence and cell fluorescence focus unit assay. Results:Without affecting cell growth, resveratrol could block the adsorption of virus, interfere with the entry of virus into cells and inhibit virus proliferation in a concentration-dependent manner. The inhibition rate could reach up to about 95%. The results of co-incubation experiment showed that 40 μmol/L resveratrol could directly kill the virus.Conclusions:This study indicated that resveratrol inhibited the activity of rabies virus in a concentration-dependent manner.
RESUMO
Objective@#To investigate the inactivating effect of soap solution on rabies virus and to explore the concentration of soap solutions which could be effective in post-exposure prophylaxis (PEP) of rabies virus infection.@*Methods@#The BSR and N2a cells were respectively infected by the mixture of different concentrations of soap solution and rabies virus CVS-11. Based on the direct immunofluorescent method (DFA) and reverse transcription PCR (RT-PCR), the inactivating effects of soap solutions on rabies viruse in BSR and N2a cells were detected, respectively.@*Results@#This experiment established the BSR or N2a cells model in 24 well cell culture plates, and we found that the upper limit of soap solution concentration which BSR or N2a cells could tolerate was 1%. The inhibitory effect test of different soap solution on rabies virus showed that the 0.5% concentration of soap solution could completely inhibit the survival of CVS-11 strain in both the BSR and N2a cells, but the 0.1% concentration of soap solution could not inhibit the rabies viruses completely.@*Conclusions@#The 0.5%-1% concentration of soap solutions could inhibit the survival of CVS-11 strain in three minutes in vivo experiment.

@#Objective To investigate the effect of postnatal music exposure on fearful behavior of prenatal stressed rats in defensive withdrawal test and the expression of gastrin-releasing peptide receptor (GRPR) in the amygdala. Methods Wistar pregnant rats were divided in stress group (n=8) and control group (n=8). The stress group were immobilized and bright lighted 45 min, 3 times a day, when gestation 11-20 days, while the control group without any stress. The new born rats from the stress group were exposed in music (SM group) or white noise (SW group) for 45 min twice a day since 1 day after born, and the rats from the control (SC) group left undisturbed. They were tested with defensive withdrawal test 60 days after birth, and the GRPR levels in the amygdala were measured with immunofluorescence and real-time PCR. Results The latency was shorter and the frequence out of the chamber was the most in the SM group of the defensive withdrawal test (P<0.001), while GRPR-positive cells and GRPR mRNA increased in amygdala (P<0.001). Conclusion Postnatal music exposure can counteract the abnormal behavior response of prenatal stressed offspring and accompany with increased expression of GRPR in the amygdala.

RESUMO
<p><b>BACKGROUND</b>The causes and mechanisms of chronic diarrhea are complex. This study aimed to explore the relationship between chronic diarrhea with normal colonoscopy findings and terminal ileum lesions.</p><p><b>METHODS</b>All cases were collected from January 2009 to June 2010. The 40 patients in the patient group had chronic diarrhea with normal colonoscopy findings. Those who had hyperthyroidism, diabetes, chronic pancreatitis, cirrhosis, atrophic gastritis, short bowel syndrome and connective tissue diseases had been excluded. The control group contained 40 healthy individuals without diarrhea. Endoscopy of the terminal ileum was applied in both groups, with the endoscope inserted into terminal ileum for more than 20 cm. The patients diagnosed of chronic diarrhea with terminal ileum lesions were treated with metronidazole and probiotics for 10-14 days.</p><p><b>RESULTS</b>Before treatment there were significant differences in endoscopy findings of the terminal ileum between the two groups (P < 0.05). In the patient group, endoscopy showed congestion, edema, erosion and ulcers in 29 cases, hyperplasia and enlargement of lymphoid follicles in 10 cases with a maximal diameter of 7-8 mm, and 1 case showed normal endoscopy results. After treatment, 35 patients recovered from diarrhea, and terminal ileum lesions disappeared in 30 cases as determined by endoscopy. In the control group, endoscopy showed scattered hyperplasia of lymphoid follicles in 5 cases, and the follicles were small with the maximal diameter being 3 mm. There was no hyperemia, edema, erosion or ulcers.</p><p><b>CONCLUSIONS</b>Chronic diarrhea patients with normal colonoscopy findings may have lesions in the terminal ileum that can be detected by endoscopy; including hyperemia, erosion, ulcers and lymphoid follicle hyperplasia. Therapeutic effect is good with metronidazole and probiotics.</p>

First, a cDNA library from Gloydius shedaoensis shedaoensis venom gland (GSSG) was constructed using SMART technique. The total RNA in a pair of GSSGs was separated and the mRNA was further isolated from it. The first-strand cDNA was synthesized through PowerScript(™) reverse transcriptase by a CDS III/3' PCR primer. A SMART IV(™) -oligonucleotide was used as the template for the synthesis of double-strand cDNA and amplified by long-distance polymerase chain reaction (LD-PCR). LD-PCR product was purified, digested, fractionated, and finally ligated to pDNR-LIB vector. The recombinant DNA was transformed into Escherichia coli DH10B. The titer of this library was 8 × 10(7) cfu/mL. Most inserts were > 1,000 bp with great recombination efficacy. 216 GSSG-cDNAs were randomly analyzed and obtained 211 expressed sequence tags (ESTs) in high quality. A total of 84 ESTs were known functional genes showing significant similarities to known function proteins, 29 ESTs were unknown functional genes showing significant similarities to unknown function proteins, and 98 ESTs were novel genes with no match in any database, which account for 39.8%, 13.7%, and 46.5% of obtained ESTs. We successfully constructed a cDNA library and characterized partial ESTs of GSSG, which provides a solid base for cloning and expressing target genes and studying the biological functions of target proteins from GSS.

Loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification method performed under isothermal conditions and has a high specificity and efficiency. We developed a LAMP assay targeting the 16S rRNA gene for rapid detection of Haemophilus parasuis. The results obtained from testing 31 H. parasuis strains and 28 other bacterial species strains showed that LAMP was as specific as, and more sensitive than, nested PCR. Fifty-five lung samples were collected from 55 healthy pigs. All the samples were negative for H. parasuis by bacterial isolation, nested PCR and LAMP, respectively. In addition, 122 lung samples were collected from 122 pigs with apparent respiratory problems. Sixty-five were positive by bacterial isolation. All the samples that were positive by bacterial isolation were also positive by nested PCR and LAMP. The LAMP assay demonstrated higher sensitivity than nested PCR, picking up 16 additional cases. The LAMP assay also gave a same result compared with the nested PCR when the two assays were used, respectively, to detect H. parasuis from samples obtained from experimentally infected pigs. We concluded that LAMP is a highly sensitive and reliable method for detection of H. parasuis infection.

Objective To study the effect of operative timing on clinical outcomes in elderly hip fracture. Methods Two hundred sixty-seven patients with hip fracture were treated from July 2006 to May 2008. The patients who had an operation within two days (the early surgery group) were compared with the outcome for those who had an operation more than two days (the later surgery group). Outcomes measured were mortality, post-operative complications, operative details, the comorbidity and the activities of daily living of patients. Results One hundred and sixteen patients were included in the study. There were 45 cases in the early surgery group, including 13 males and 32 females. The patients ranged from sixty-five to eightyeight years old, with an average age of 78.76 years. While there were 71 patients in the late surgery group,including 24 males and 47 females. The patients ranged from sixty-six to one hundred and three years old,with an average age of 80.00 years. The demographic data of patients show no significant difference in two groups. There was no difference in intraoperative conditions such as anesthesia, amount of bleeding, type of fixation between two groups. Patients in early surgery group experienced shorter length of hospital stay, and fewer pulmonary complications. The mortality of early surgery group do not show a significant increase at discharge, 6 month, 12 month postoperatively compared to that of the later surgery group. However patients in the early surgery group show a significant increase of ADL scores at discharge, 6 month postoperatively,but not at 12 month. Conclusion The timing of surgery has an impact on clinical outcome in elderly hip fracture. Early surgery was associated with improved function in the first 6 month postoperatively, but not 12months, but it was not associated with mortality.
RESUMO
Objective:To study the effect of combined acupuncture and rehabilitation training on early-stage Barthel index of ischemic stroke cases.Method:Fifty ischemic stroke cases were randomized into a treatment group of 24 cases and control group of 26 cases.In addition to routine internal treatment methods,rehabilitation training was applied to cases in the control group,and combined acupuncture and rehabilitation training were applied to cases in the treatment group.Warming and reinforcing manipulations were applied to Jianyu (LI 15),Quchi (LI 11),Hegu (LI 4),Yanglingquan (GB 34),Yinlingquan (SP 9),Zusanli (ST 36),and Sanyinjiao (SP 6),20 min of needle retaining for each point in one treatment.Then the scores of clinical neurological impairment and Barthel index of stroke cases were evaluated before the treatment and 3 weeks after respectively.Results:The significant progress and progress cases in the treatment group were 14 and 12 respectively,whereas that in the control group were 6 and 11 respectively,coupled with 7 cases of no progress.The therapeutic effect in the treatment is substantially better than the control group (P<0.05).There was no significant difference (P>0.05) in neurological impairment and scores of Barthel index of the two groups before the treatment,whereas significant difference (P<0.05) after the treatment.The scores of neurological impairment in the treatment group were significantly reduced after the treatment (P<0.05),and the scores of Barthel index were significantly increased (P<0.05).Conclusion:Combined acupuncture and rehabilitation training can produce significantly better effect on early neurological impairment and Barthel index of stroke cases than rehabilitation training alone.
RESUMO
Objective To study the relationship between viral infection and chronic obstructive pulmonary disease (COPD),and the effect of viral infections on the changes of Th1/Th2 in COPD patients. Methods The se-ra from 81 patients with acute exacerbations of COPD,25 patients with stable COPD and 22 healthy subjects were tested for specific IgM of respiratary syncytial virus(RSV) ,herpes simplex virus type 1 (HSV-1), parainfluenza vi-rus (PIV), adenovirus (ADV) and cytomegalovirus (CMV) by indirect enzyme-linked immunosorbent assay (ELISA). Supernatant INF-γ and IL-4 cultured with PHA were determined. Results The positive rates of IgM in patients with acute exacerbations of COPD compared with those in patients with stable COPD and healthy subjects were significantly different(P <0.001 ). The level of INF-γ, and IL-4 in patients with acute exacerbations of COPD and stable COPD compared with normal control group;the level of INF-γ (242±43) and the of IL-4(42±9) in pa-tients with acute exacerbations of COPD was not significantly different as compared with the level of INF-γ( 198±32) and the level of IL-4(56±11 ) in patients with stable COPD (P<0.05), but the level of INF-γ was increased (90±18)and IL-4 was decreased (141±24) in control group (P<0.05). Compared with those in IgM negative group, the levels of INF-γ were significantly higher and the levels of IL-4 were significantly lowerIL-4 in lgM positive group( P<0.01 ). Conclusion Virus infection is a rather important factor in acute exacerbations of COPD, and COPD is characterized by a predominance of Th1-type response,and there is more significant Th1 response predomi-nance in COPD with virus infection.
RESUMO
Objective To evaluate the value of admission test of fetal heart rate and artificial rup-ture of membrane in predicting fetal distress in labor. Methods 658 pregnant women who had been pregnant for 33+5 to 43 weeks and delivered spontaneously in 24 hours were divided into low risk group(598 cases) and hign risk group(60 cases) according to their admission test. The admission test, result of deliv-ery, amniotic fluid contamination and Apgar scores of newborns were analyzed. Results 515 cases were reactive type(78.27%), 72 cases were equivocal type(10.94%) and 71 cases were ominous type(10.79%). Total incidence of neonatal asphyxia were 6.53%,and it was 1.94% and 33.08% in reactive type subjects and ominous type subjects, respectively. The rates of anmiotic fluid contamination were 20. 97% and 67.61% in reactive type subjects and ominous type subjects (P<0.01). The incidence of reactive type and equivocal type of amniotic fluid contamination and neonatal asphyxia were significantly lower in the low risk group than those in the high-risk group (P<0.05). Conclusions Reactive type of admission test can ensure safety of fetus during the subsequent four to five hours. Admission test of fetal heart rate and artifi-cial rupture of membrane can be used to predict fetal outcome in labor.

RESUMO
Objective To explore a reasonable treatment for intertrochanteric hip fractures in the aged patients by comparing the fixation effects of cannulated compression screws and intramedullary fixation nails. Methods From January 1998 to December 2004, in our department 123 old patients with intertrochanteric hip fracture were fixed with cannulated compression screws or intramedullary nails. They were followed up and their complete clinic data kept. According to the Evans classification, of the 51 patients who received treatment with cannulated compression screws for their anterograde intertrochanteric hip fracture, 14 were type Ⅰ , 24 type Ⅱ , 10 type Ⅲ and three type Ⅳ , while of the 72 patients who received treatment with intramedullary nailing, 10 were type Ⅰ , 12 type Ⅱ , 28 type Ⅲ , 14 type Ⅵ , and eight retrograde intertrochanteric hip fractures. A retrospective comparison was made between the old patients treated with the two different fixation devices in terms of operative time, blood loss, transfusion, average hospitalization time, intraoperative and postoperative complications, functional recovery one year postoperatively and treatment expenses. Results The differences between the two groups in operative time, blood loss, transfusion, treatment expenses were of statistical significance (P0.05). Conclusions Cannulated compression screws should be chosen for old patients with anterograde intertrochanteric hip fractures of Evans types Ⅰ & Ⅱ or of Evans types Ⅲ & Ⅳ who are at a high risk, in a poor health or severely osteoporotic state. For patients with unstable Evans types Ⅲ & Ⅳ or with retrograde intertrochanteric hip fractures, intramedullary nails are suitable.
