Objective To evaluate the application of M2A capsule endoscopies ( CE) in the diagnosis of digestive tract diseases. Methods Forty - five patients (26 males, 19 females) , suffered from gastrointestinal bleeding, abdominal pain or chronic diarrhea were referred to this study and underwent capsule endoscopies. Their average age was 47. 8 years old (a range of 15 - 78). Capsule endoscopies were performed with the Given M2A video capsule system. The conventional diagnostic procedures (including small bowel radiograph, gastroenteroscopy, colonoscopy, etc. ) were done in 31 patients before or after the CE, thus the results of both procedures were compared. Results Among 45 patients, 44 have completed CE successfully. Any complication never experienced. The quality of photos was excellent. The significant pathological findings were revealed in 37 patients, diagnostic yield was therefore 84. 1% . Patients with esophagogastric diseases, small bowel diseases and colon diseases were found in 5,29 and 3 cases respectively. Thirty -one patients received a conventional diagnostic procedure before or after CE. Twenty one of them suffered from GI bleeding, pathological changes were found in 17 patients by capsule endoscopies, only 4 patients by conventional procedure; five of them suffered from abdominal pain, pathological changes were found in 5 patients by CE, only 2 patients by conventional procedure; 4 of them suffered from chronic diarrhea, pathological changes were found in 4 patients by CE, only 1 patient by conventional procedure. The pathological sites located by CE were quite similar to those by conventional diagnostic work-up. Conclusion CE has the advantages of high safety, excellent visualization and precise localization. Its efficiency in diagnosis is much better than that of conventional procedure, and is indispensable in the diagnosis of digestive tract diseases.

OBJECTIVE: To investigate the bacteria distribution, drug bacterial sensitivity characteristics of the rural chronic rhinosinusitis (CRS). And to explore the effect of antibiotic on pathogenic bacteria culture. METHOD: Choose nasal sinus secretions from 115 CRS patients living in rural areas. Aerobic bacteria culture, anaerobic bacteria culture and drug sensitive test were procedured for each sample. At the same time the use of antibiotics nearly 2 months and nearly 2 weeks were collected. RESULT: Among one hundred and fifteen specimens, 17 kinds of germs were detected in 37 cases, the positive rate of aerobic bacteria was 32.17%. Staphylococcus aureus and epidermis staphylococcus aureus the most common type of aerobe in CRS patients at rural areas. There was negative result in the anaerobic bacteria culture of 17 maxillary sinus specimen. The cases of using antibiotics nearly 2 months was up to 90, accounting for 78.26%. Nearly 2 weeks, 73 cases, accounting for 63.48%. The chi-square analysis showed high bacterial culture rate, in chronic rhinosinusitis with nasal polyps (CRSwNP group), which revealed correlation between bacterial infection factors and nasal polyps formation. For CRS patients with positive result of bacterial culture, they were sensitive to ofloxacin, cefotaxime, organism, ciprofloxacin, magnitude cephalosporin, and were drug fast to penicillin G, ampicillin, erythromycin. CONCLUSION No specific differences was found in the bacteria distribution of rural CRS. antibiotics abusage in rural CRS patients and the anaerobic bacteria culture techniques is the main factor resulting in low culture rate. Rational use of antimicrobial agents should be established on the basis of the bacterial culture and drug sensitive test.

ObjectiveTo investigated the effects of Rhodiola Compound on improving the intellective function in mice and provide the basis for clinical application.MethodsMice were divided to different groups of three doses of rhodiola compound (0.3 g/kg,0.6 g/kg,1.2 g/kg) and swimming abilities were tested.Other mice were administrated single dose of compound rhodiola( 1.2 g/kg) and training by Morris water maze.Drug's improving intelligence function was assessed using memory acquisition impaired models made by scopolamine or alcohol.When the Morris water maze test was finished,mice were killed and brains were removed immediately to measure SOD and NO levels.ResultsGroups of three doses of compound rhodiola could significantly prolong the swimming time(P ＜ 0.05,P ＜ 0.01 ).Compound Rhodiola group can significantly reduce the swimming distance than the untreated group( ethanol model group:(26 906.6 ± 2769.7 ) mm,RCE treated group:( 19 586.1 ± 6826.7 ) mm ; P ＜0.05 ).Swimming distance and time of cross-platform quadrant was significantly increased,comparing with model group (P ＜ 0.05 ).Compound Rhodiola significantly enhanced the activity of mouse brain's SOD ( Scopolamine model group:( 150.3 ± 17.7 ) U/ml,RCE treated group:( 197.9 ± 16.8 ) U/ml ; P ＜ 0.05 ) and NO levels ( Scopolamine model group:( 44.7 ± 16.7 ) μmol/gprot,RCE treated group:( 65.4 ± 14.5 ) μmol/gprot ; P ＜ 0.05 ) significantly.ConclusionCompound Rhodiola could promote mice learning and memory function,SOD and NO in brain maybe play a important role in this effect.

Twenty-four adult rabbits(body weight 1500—2000 gm),under light urethane ana- thesia(1 gm/kg),were subjected to craniotomy.The symmetrical areas of the parietal cortex were exposed and each side was covered by a filter paper which had been soaked with any one of the following drugs:(1)2% Strychnine(Sulphate),(2) 1‰ Stry- chnine,(3)20% KCI,(4)2% KCl.The normal saline was used for the controls. Thirty minutes later,all animals were killed by decapitation.The cortical areas were rapidly removed within one minute and stained with the following method:(1)Gomori's method for acid phosphatase(ACP),(2)Unna's method for ribonucleic acid(RNA), and(3)Toluidine blue stain for Nissl bodies.The cevical cord(C3-4)was also re- moved in some animals and stained for RNA.In five animals,the EEG records were obtained from the cortical surface with the silver-silver chloride nonpolarized electrodes. The EEG results confirmed the established experiments that when 20% KCl was placed locally,the amplitudes of the EEG waves became markedly decreased,while 2% Stry- chnine was applied,the typical 'Strychnine Spikes'appeared consistently. The local application of 20% KCl did not produce any significant effect on the RNA contents of the horizontal cells(Cajal's cells)in the lst layer.But the pyramidal cells of the 2nd,3rd layers exhibited a typical central chromatolysis,i.e.,RNA decreased or disappeared,nucleus became eccentric,Nissl bodies underwent dissolution.The granu- lar cells of the fourth layer also showed central chomatolysis,but less marked.The ganglion cells and polymorphic cells in 5th,6th layers did not differ apparently from that of the normal saline controls.2% KCl produced the similar effect although the de- generative changes were not so severe as compared with that of the 20% KCl. Local application of 2% Strychnine did not alter the RNA levels of the Cajal cells. The RNA content of pyramidal cells in 2nd—3rd layers decreased to a considerable de- gree,but the typical chromotalytical changes were absent.The RNA of the large pyramidal cells in the 5th layer appeared as clusters of large granules.The RNA levels of 4th,6th layer showed no considerable changes as compared with that of the normal saline controls,1‰ Strychnine had no significant effect on the RNA content of the cere- bral cortex. The RNA of the anterior horn cells of the cevical cord was the same as the control animals no matter what drugs had been applied. 20% KCl enhanced the ACP reaction of the whole cortex,especially the 2nd—3rd layers.2% KCl produced the same effect but to a lesser degree.1% Strychnine also increased the ACP activities of the 2nd—4th layers.But 1‰ Strychnine had no signifi- cant effect. Based on the mentioned results,the significance of RNA and ACP for the functions and the functional relations of nerve cells between cortical neurons were discussed.

Purpose: The purpose of this study was to explore the experiences of caregivers in long-term care facilities as they implement palliative care. Although palliative care has been available in Taiwan for more than 30 years, it is often provided in hospitals, few models in the long-term care facilities. Methods: Semi-structured interviews using grounded theory methodology and purposive sampling. Two small long-term care facilities that had performed well in palliative care were selected from eastern Taiwan. A total of 12 caregivers participated in in-depth semi-structured face-to-face interviews. Results: Four major stages in the implementation of palliative care were identified: (1) feeling insecure, (2) clarifying challenges, (3) adapting to and overcoming the challenges, and (4) comprehending the meaning of palliative care. The core category of these caregivers as “the guardians at the end of life” reflects the spirit of palliative care. Conclusion This study demonstrates that successful palliative care implementation would benefit from three conditions. First, the institution requires a manager who is enthusiastic about nursing care and who sincerely promotes a palliative care model. Second, the institution should own caregivers who possess personality traits reflective of enthusiasm for excellence, unusual ambition, and a true sense of mission. Third, early in the implementation phase of the hospice program, the institution must have the consistent support of a high-quality hospice team.

BACKGROUND:Previous studies concerning neuromechanism of acupuncture for regulating gastric function mainly focused on peripheral nerve, involving in central nervous system. In particular, there are few studies addressing higher central nervous system.
OBJECTIVE:To explore the effects of acupuncture at Neiguan (PC6) and Zusanli (ST36) on gastric-related neurons in the hypothalamic paraventricular nucleus.
METHODS:Using microelectrode extracellular recording technique, gastric related neurons in the paraventricular nucleus were found in gastric distension rats. Stimulation was conducted for 30 seconds by hand acupuncture at Neiguan and Zusanli. The effects of acupuncture on gastric-related neurons in the paraventricular nucleus were observed.
RESULTS AND CONCLUSION:The discharge of 109 neurons in the hypothalamic paraventricular nucleus of 60 rats was recorded. A total of 56 gastric-related neurons of the 109 neurons were observed. The number of neurons response to acupunctures at Zusanli, Neiguan, Pishu (BL20) and Weishu (BL21) were respectively 44, 47, 29, and 33, with the reaction proportion of 78.57%, 83.47%, 51.79%and 58.93%. Results suggested that there exist gastric distension stimulation and acupuncture stimulations from neurons soma to visceral reaction in the hypothalamic paraventricular nucleus, which simultaneously participates in the regulation of acupuncture on the gastric function.

BACKGROUND:Preliminary studies of our research group mainly focus on the role of nucleus of solitary tract in gastric noxious stimulation and acupuncture point, while dorsal nucleus of vagus nerve, nucleus of solitary tract and area postrema are the necessary component for vagus nerve complex, and dorsal nucleus of vagus nerve plays a crucial role in the regulation of gastric functions. OBJECTIVE:To observe the effect of acupuncture at Zusanli, Neiguan, Pishu and Shenshu acupoints on the gastric-related neurons in dorsal motor nucleus of the vagus nerve. METHODS:The gastric related neurons in dorsal motor nucleus of the vagus nerve of gastric distension rats were identified using extracellular recording technique, according to neuroelectrophysiology method. Acupuncture stimulation was given to Zusanli, Neiguan, Pishu and Shenshu for 15 seconds. The effect of body stimulation on the gastric distension related neurons in dorsal motor nucleus of the vagus nerve of rats was recorded. RESULTS AND CONCLUSION:Among the involved 24 rats, 90 neurons at paraventricular hypothalamic necleus exhibited discharge. Among the discharged neurons, 54 neurons were related to gastric distension. After acupuncture stimulation at Zusanli, Neiguan, Pishu and Shenshu, there were 44, 39, 38, 27 neurons giving a response, the reaction rate was 82%, 72%, 70%and 50%, respectively. Acupunture at different nerve segment acupoints can activate the dorsal motor nucleus of the vagus nerve to different degrees, which is involved in the regulation of gastric motility.
