Objective: To observe the clinical efficacy of intradermal needle therapy for urinary retention after cervical cancer surgery. Methods: A total of 100 patients with urinary retention after cervical cancer surgery were randomized into a control group and an observation group, with 50 cases in each group. The control group was treated with basic nursing only, and the observation group was treated with additional intradermal needle therapy. Both groups were treated for 2 courses of treatment. The main symptom scores and residual urine volume of the two groups were observed before and after treatment, and the inpatient time, catheter indwelling time and the clinical efficacy were compared between the two groups. Results: The total effective rate was 96.0％ in the observation group and 88.0％ in the control group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the main symptom scores and residual urine volume in both groups decreased significantly (all P<0.05), and the scores and residual urine volume in the observation group were significantly lower than those in the control group (all P<0.05). The inpatient time and catheter indwelling time in the observation group were significantly shorter than those in the control group (both P<0.05). Conclusion: Intradermal needle therapy has an obvious effect in improving symptoms of urinary retention after cervical cancer surgery, and the effect is significantly more persistent than that of simple basic nursing.

BACKGROUND: The marginal division, a new sub-region in rat brain striatum discovered in recent decades, has been found to closely relate to learning and memory function of the brain. The immediate-early genes such as c-fos and c-jun participate in the signal transduction of learning and memory in the marginal division. But what other intermediate events are initiated in the marginal division in the process of learning and memory?Cyclic adenosine monophosphate (cAMP) response element-binding protein (CREBP) is an molecule essential for the formation of long-term memory,and investigation of the expression and distribution of phosphorylated CREBP in the striatum may help understand the signal transduction mechanism in the striatum during learning and memory at the molecular level.OBJECTIVE: To investigate the expression of phosphorylated CREBP in rat brain stratum during learning and memory process.DESIGN: Completely randomized controlled study.SETTING: Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA.MATERIALS: This experiment was conducted in the Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA between April and August 2003. Totally 48 normal male adult SD rats were provided from the Experimental Animal Center of First Military Medical University, and after two Y-maze tests, 40 rats were selected for this study (MG-2 type, Sanshengxing electricity company).METHODS: The 40 SD rats were randomized into 4 equal groups. The rats in the first group were subjected to training to acquire dark avoidance reflex in a Y maze, those in the second group underwent sham training with only light stimulation in the Y maze without electricity on the floor.The rats in the third group were trained in the Y maze with electricity on the floor but not light stimulations, with the rest 10 rats serving as the control group subjected to sham training in the Y maze without either electric or light stimulations. After the training in the Y maze, the rats were sacrificed immunohistochemical detection of phosphorylated CREBP expression in the brain striatum.MAIN OUTCOME MEASURES: Expression of phosphorylated CREBPin rat brain striatum.RESULTS: All the 40 rats enrolled in this study were examined for phosphorylated CREBP expression. Positive expression of phosphorylated CREBP was observed in the medial marginal division of the brain striatum after the rats were trained in the Y maze with electric stimulation, but no obvious expression was seen in rats in the sham training or control groups.Massive expression of phosphorylated CREBP could be observed, typically,in the hippocampus, front prefrontal lobe cortex and cingulate gyrus of the rat brain.CONCLUSION: The transcriptional factor phosphorylated CREBP in the marginal division of the striatum participates in the signal transduction for learning and memory in rats receiving Y maze training to acquire dark avoidance reflex.

ISG15, the first ubiquitin-like molecule identified two decades ago, is encoded by interferon stimulated gene 15 ( ISG 15), where its robust expression can be induced by viral infections or interferon treatments. ISG 15 conjugate to other proteins as the ubiquitin and was found to be involved in innate immune response. However, the functions of ISG15 modification remained unclear. We cloned bovine ISG15(bisg15) into a prokaryotic expression vector pET28a( + ) with a His-tag to generate a soluble form of bISG15 fusion protein, and purified with Ni-NTA Sepharose chromatography. The purified protein was concentrated and used to immune Balb/c mice to raise the antiserum, which could specifically recognize bISG15 expressed in eukaryotic cells by Western blot analysis. The concentrated bISG15 protein and its antiserum were then used to establish an in vitro bISG15 modification system. Our studies have demonstrated that cellular proteins could be conjugated to bISG15 with this system.

BACKGROUND: Hippocampal structure in brain is the division related to learning and memory, generally it is closely relevant to spatial cognitive activity. Marginal division of striatum is a latest discovered subdivision related to learning and memory function of brain, whether is its learning and memory function different from that in hippocampus?OBJECTIVE: To compare the difference, function and importance in learning and memory function between marginal division of striatum and hippocampus in brain and observe the difference in escape learning and memory between marginal division of striatum and hippocampus.DESIGN: Completely randomized controlled experiment.SETTING: Institute of Neuroscience in Zhujiang Hospital Affiliated to First Military Medical University of Chinese PLA.MATERIALS: The experiment was performed in Institute of Neuroscience in Zhujiang Hospital Affiliated to First Military Medical University of Chinese PLA from March 2002 to July 2003. Totally 109 normal male adult SD rats were employed and 75 rats of them were screened as the qualified animals by twice Y-maze test. Randomly, 25 rats were divided into damaged marginal division of striatum group (DMD group), 10 rats were into bilateral fimbria-fornix transection group (FFT group), 30 rats were into the control of marginal division of striatum (MD control) and 10 rats were into the control of bilateral fimbria-fornix group (FF control). After 24 hours training in Y-maze,In DMD group, 10 g/L kainic acid 0.1 to 0.2 μL was used to damage bilateral marginal division of striatum of rats. In MD control, physiological saline of minim dose was injected in bilateral marginal division of striatum of rats. In FFT group, bilateral fimbria-fornix was transectioned. In FF control, the cortical tissue of the superficial layer of bilateral fimbria-fornix was transectioned. The operation was done on the second day after the 2nd screening. The behavior of rats in learning and memory was observed in Y-maze on the 5th day after operation (during 30 times of maze test, if success frequency ≥ 15,normal capacity of learning and memory was identified.).MAIN OUTCOME MEASURES: Success frequency of rats in different groups in Y-maze learning before and after operation.RESULTS: Of 109 normal male adult SD rats, 75 rats were screened to be qualified after twice Y-maze test. During the experiment, 3 rats were died and other 32 rats fell into disuse for the drug or physiological saline was not injected accurately to the marginal division of striatum. Terminally, 40 rats entered the analysis in total, of which, 11 rats were in DMD group, 9 rats in MD quency in Y-maze learning of rats in DMD group after operation was lower than MD control, FFT group and FF control [(9.27±4.29) times, (22.56±4.25)frequency in Y-maze learning of rats in DMD group after operation was also significantly lower than that before operation [(9.27±4.29) time, (18.27±3.07)FFT group was basically same as FF control and MD control (P=0.660 and P=0.489) and it was basically same to the success frequency in Y-maze learning before operation (P=0.700).CONCLUSION: The learning of Y-maze in rats with damaged marginal division of striatum was remarkably reduced and there was no obvious change in learning and memory between the rats with fimbria-fornix transaction and without transaction. It is verified that marginal division of striatum can reflex complex learning and memory behavior in electric Y-maze test, which cannot be achieved in hippocampus. It is further explained the difference of the two divisions in controlling learning and memory in cerebrum, the marginal division of striatum is able to control hippocampus in learning and memory function.

OBJECTIVETo investigate the effects of oral cancer-associated fibroblasts (CAFs) on lymphangiogenesis in oral squamous cell carcinoma (OSCC).

METHODSCAFs and normal fibroblasts (NFs) were obtained from the tissues of patients with OSCC who did not receive radio-chemotherapy before operation. And the CAFs and NFs were isolated by method of tissue block and identified by immunohistochemical staining. The effects of CAFs (group A) and NFs (group B) to human lymphatic endothelial cells (HLEC) were detected by using a 24-multiwell transwell cell culture chamber. DMEM sugar medium was as blank control group. The number of proliferative, migratory, invasive and tubes of HLEC were counted under inverted phase contrast microscope.

RESULTSThe proliferative number of HLEC of group A for 96, 144, 196 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01). The migratory and invasive number of HLEC of group A for 96 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01). The number of tube formation of HLEC of group A for 24 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01).

CONCLUSIONCAFs promote HLEC's proliferation, migration, invasion, tube formation, and these effects are stronger than NFs.

Background and purpose:Neuroendocrine neoplasm is one kind of infrequent neoplasms from neuroendocrine cell and peptidergic neurons. This study aimed to investigate the epidemiology and clinicopathological characteristics of neuroendocrine neoplasms (NEN) in Dalian. Methods: We retrospectively analyzed all neuroendocrine neoplasms patients in First Afifliated Hospital of Dalian Medical University from 2000 to 2013. The epidemiology characteristics, pathogenic sites and pathological types were reviewed, and the differences between gender and age were also analyzed. The statistics analysis such as independent-samples t test and one-way ANOVA and chi-square test were performed. Results:There were 279 NEN cases, including 166 male and 113 female patients (male:female=1.14:1), detection rate was 0.258%. The mean age of all cases was 59.4±17.1 (20-83), for male 58.9±19.4 (20-81) and female 61.7±15.0 (29-83). There was no statistical signiifcance of detection rate and mean age between male and female patients. Digestive system was the most common occurred site of NEN (71.68%), then was the respiratory system (20.79%). There was no statistical significance of pathogenic sites between male and female.In all case, 132 with neuroendocrine tumor (47.31%), 140 with neuroendocrine cancer (50.18%), 7 with mixed adenoneuroendocrine carcinoma (2.51%). There was no statistical signiifcance of pathological types between male and female (P>0.05).Conclusion:Recently, the detection rate of neuroendocrine neoplasms was raised in Dalian, but there was no signiifcance differences in detection rate,pathogenic sites and pathological types between male and female.
