Methods To adopt phenomenology method of qualitative research, collecting data by the direct participation, observation, half structural formula thorough interview and other methods. To establish coding and refine theme. Results Four themes of the rectal cancer patients experience of perioperative therapeutic communication were generalized: emotional adaptation, actively coping with surgery, intraoperative cooperation, postoperative rehabilitation and self-care. Conclusions Application of therapeutic communication system can effectively interfere with patients cognitive behavior, improve communication ability of nurses and extended the nursing service connotation.

Objective To understand the dietary intake of pregnant women, and try to give a reasonable sug-gestion to promote fetal development. Methods 400 pregnant women in Fushan city were enrolled in this study and their dietary intake were investigated, then the software of Analysis of pregnancy nutrition guidance system was used to make nutrition analysis. Results The ratio of the energy in each pregnancy provided by dietary protein, carbohy-drate and fat were relatively appropriate. But the intake of dietary calcium, ferrum, zinc, vitamin B1 and vitamin B2 in early pregnancy were very low, the intake were respectively 764.51 mg, 26.94 mg, 15.71 mg, 1.12 g, 1.13 g. Each pregnancy the ratio of high-quallty protein in total protein intake were more than 50%, an average protein RNI% was 48.50%. Conclusion The dietary style of pregnant women is relatively reasonable. But they should strengthened nutritional guide to intake more calciuro,ferrum, zinc,vitamin B1 and vitamin B2.

Re-sults There were significant differences between the two groups about all the indexes which had indicated the delivery. Conclusions Correct psychoanalysis and proper nursing intervention and effective release the pains for parturient women, and then decrease the incidence rate of medical negligence.

Objective To explore the diagnostic value of plasma fetal DNA level in preeclampsia.Methods Thirty cases of pregnant women with preeclampsia(at 33 weeks and 3 days) and 30 cases of normal pregnant women(at 34 weeks and 3 days) were selected.All the pregnant women carried a male fetus by B-ultrasound,and were sampled at gestational 20 weeks,third trimester and at 1 hour,3 hours,6 hours after delivery.SRY levels in maternal blood were quantitated by polymerase chain reaction(QF-PCR).The endotheliotoxin(ET) level was measured with RIA.Results (1) Mean fetal DNA level of patients with preeclampsia at 20 weeks of gestation was(316?61)copy/ml.They were(266?79)copy/ml,(396?91)copy/ml,(165?43) copy/ml for light and severe preeclampsia women and normal pregnant women,respectively.Maternal blood fetal DNA levels in pregnant women with preeclampsia at 20-weeks of gestation were significantly higher than those normal pregnant women(P

Objective To investigate the effects of Jiawei Wuzi Yanzong Pill and its components on central cholinergic system in the model mice with learning and memory disorders induced by scopolamine. Methods Mice were treated by Jiawei Wuzi Yanzong Pill and its components for 15 days and induced by ip scopolamine. After the experiment in Morris water maze, the content of acetylcholine and the activity of acetylcholinesterase from brains of mice were determined by colorimetry. Results Significant differences were observed between model group and naked group that the content of acetylcholine and the activity of acetylcholinesterase from brains of model mice were decreased (P 0.05). Conclusion Jiawei Wuzi Yanzong Pill and its components could improve the function of central cholinergic system by increasing the content of acetylcholine and the activity of acetylcholinesterase and possesses a certain preventive effects on mice with learning and memory disorders induced by scopolamine.

Objective To investigate the protective effects of melatonin and possible mechanisms on rats with alco-holic fatty liver (AFL). Methods All rats were randomly divided into 4 groups: normal group (n = 10), model group (n = 12) and melatonin groups (10 mg / kg, 20 mg / kg; n = 10, respectively). The model of rats’ alcoholic fatty liver was induced by intragastric influsion of ethanol for 8 weeks. The melatonin groups’ rats received melato-nin by intraperitoneal injection after intragastric infusion of ethanol. Histopathological changes were evaluated by hematoxylin and eosin staining. The expressions of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected by immunohistochemical methods. The detection of aspartate aminotransferase (AST) levels and alanine transarninase (ALT) levels and the total bilirubin ( TBIL) levels in serum were provided by routine laboratory methods using an autoanalyzer. The levels of malondialdehyde ( MDA) and activities of glutathione peroxidase ( GPx) were measured by spectrophotometry. Results Compared with the normal group, the liver cells of the mod-el group showed obvious steatosis and significant swelling. However, less degree and less extensive of steatosis and swelling were observed in the melatonin groups. Compared with the normal group, the levels of ALT, AST and TBIL in serum and the levels of MDA in liver homogenates were significantly increased in the model group (P <0. 01), and the activities of GPx were distinctly decreased in the model group(P < 0. 01). But in the melatonin groups, the levels of ALT, AST and TBIL in serum and the levels of MDA in liver homogenates were decreased (P< 0. 01), and the activities of GPx were increased (P < 0. 01). Additionally, melatonin lessened the expression of TNF-α and IL-6 in liver obviously (P < 0. 01). Conclusion Melatonin may inhibit the development of alcoholic fatty liver and its possible mechanism is the ability to resist oxidative stress and lessen the expression of TNF-α and IL-6 and other relevant factors in liver.

ObjectiveTo investigate and evaluate the depression in patients with type 2 diabetes.Methods62 patients with type 2 diabetes (30 having complications, 32 not having complications) and 20 normal controls were assessed by Hamilton Depression Rating Scale (HRSD) of Peking University PES Mental State Application System.ResultsThe HRSD total scores of diabetics were higher than that of normal controls, and scores of diabetics with complications were higher than that without complications (P<0.05). The scores of anxiety/somatization and cognitive disturbance of diabetics were all higher than that of normal control (P<0.05).The scores of sluggish, dyssomnia of diabetics with complications were higher than that of normal controls (P<0.05), but there was no difference between diabetics without complications and normal controls (P>0.05). The scores of changing at day and night, weight, and the despair feel of diabetics were not obviously different with that of normal controls (P>0.05).ConclusionThe diabetics are often companioned with depression, and more severe when having complications.

BACKGROUND: We can investigate mechanism of endogenous neuroprotection in rat cerebral hypoxic tolerance trial. OBJECTIVE: To observe the characteristics of cerebral hypoxic tolerance in rat models with cerebral hypoxic preconditioning. DESIGN: Randomized controlled observation. SETTING: Department of Neurology, China-Japanese Friendship Hospital, Jilin University. MATERIALS: The experiment was performed in the Basic Animal Experimental Center, China-Japan Friendship Hospital, Jilin University from April 2003 to April 2004. Inbred line healthy Wistar rats, of either sex, with the body mass of 200-300 g, were randomly assigned into normal control group (n=6), sham operation group (n=6), ischemic control group (n=20), hypoxic preconditioning (3 hours, 8% O2 and 92% N2) plus ischemic group (n=60) (according to different hypoxic phases, there were 5 time phases: 30 minutes, 1, 3, 5 and 6 hours with 12 rats in each time phase), hypoxic preconditioning group (n=18) [according to different hypoxic phases, there were 3 time phases: 1, 3 and 5 hours with 6 rats in each time phase, 3 rats received TTC staining and 3 rats received hematoxylin and eosin (HE) staining]. METHODS: ①Hypoxic preconditioning: Firstly, natrica calx was put into closed glass container to absorb CO2 and O2, secondly, mixed gas of 8% O2 and 92% N2 was input, and then animals were put into the container, 3 rats each time. Temperature and humidity were kept steadily. ②Permanent ischemic middle cerebral artery rat models were established. ③The models were determined with a series in procedures: neurological score, infarcted volume evaluation, pathological sample preparation, immunohistochemical staining, imaging analysis and so on. ④The data were compared in groups with variance analysis.MAIN OUTCOME MEASURES: Changes in cerebral infarcted volume, neurological score and pathological morphology in rats of experimental group and control group. RESULTS: Neurological score in the hypoxic preconditioning (8% O2, at hours 1, 3 and 5) plus ischemic group was lower than in the ischemic control group(P＜0.01). Neurological score at minute 30 and hour 6 after hypoxia (8% O2) had insignificant difference in the ischemic control group. Mean cerebral infarcted volume ratio in the hypoxic preconditioning (8% O2, at hours 1, 3 and 5) plus ischemic group was lower than in the ischemic control group(P＜0.01). Mean cerebral infarcted volume ratio after hypoxia (8% O2, at minute 30 and hour 6) had insignificant difference with ischemic control group (P＞0.05). CONCLUSION: Hypoxic preconditioning in rats can effectively release nerve injury induced by focal cerebral ischemia, suggesting that it has protective effect on brain. The procedure of establishing cerebral ischemic tolerance models with hypoxic preconditioning, which is simple and stable, with little injury on experimental animals, is a useful tool for studying cerebral ischemic tolerance.

A rarely reported postoperative complication following biliary surgery,and to discuss its possible mechanism.This article summarizes I reported HSB case that developed after laparoscopic cholecystectomy in our department and 9 other cases reported in literature.HSB occurred most frequently after simple cholecystectomy in addition to post operative bile duct exploration with cholecystectomy or endoscopic retrograde cholangiopancreatography.The main clinical presentation of HSB was paroxysmal colic in the upper abdomen early in the postoperative period,which could be induced after a meal.Imaging revealed subcapsular hepatic fluid collection,and successful treatment involved placement of a percutaneous drain in the biloma.The mechanism of HSB still needs to be clarified even though it is a rarely reported postoperative complication following biliary surgery.We hypothesize,after analyzing these 10 cases,that sphincter of Oddi dysfunction after biliary surgery and the subsequent persistence of high biliary system pressure may be the root cause of HSB formation.More awareness should be paid to the changes of the sphincter's motility after biliary surgery and its related complications (biliary colic,HSB etc.).
