Chinese Journal of Urology 2000;0(05):-
Objective To approach the pathogenesis,diagnosis and treatment of cystitis glandularis. Methods A retrospective analysis of clinical data of 172 cases of cystitis glandularis was made and the experience on its diagnosis and treatment was summed up.Transurethral electroresection was performed in 132 cases.Of these cases,93 with lower urinary obstruction simultaneously underwent electroresection of pathological foci of lower urinary obstruction caused by bladder-neck contracture or hyperplasia of seminal colliculus,and 16 cases with complicated hymenal lesion at meatus urinarius received resection and plastic operation of hymenal lesion.Instillation of drug at bladder trigone was performed in 40 patients who refused surgical operation and in 16 patients whose symptoms still existed after electroresection. Results Seventy-eight of the 132 cases in which transurethral electroresection had been performed showed normal findings in cystoscopy during a follow-up study of 6~36 months;their symptoms disappeared,the cure rate being 58%.Thirty-two of the 56 cases for whom bladder trigone instillation had been performed had their symptoms subsided or remitted,the effective rate being 57%. Conclusions The lower urinary obstruction is the common cause of leading to cystitis glandularis.Transurethral electroresection or electrovaporization is the main method of treating cystitis glandularis.It can also simultaneously remove obstructive foci which causes cystitis glandularis.The bladder trigone instillation is an effective method of treating cystitis glandularis.

Objective To investigate the factors related with swallowing function after stroke. Methods Stroke patients with dysphagia were reviewed, 296 cases with pseudobulbar paralysis, and 82 cases with bulbar paralysis. Swallowing function was evaluated with videoflu-oroscopic swallowing study (VFSS). The variable of age, sex, Body Mass Index (BMI), scores of National Institutes of Health Stroke Scale (NIHSS), Simplified Fug-Meyer Assessment (FMA) and modified Barthel Index (MBI), intubation, aspiration, length of hospitalization (LOH), and initiation of rehabilitation intervention were analyzed with Logistic regression. Results Age, NIHSS score, intubation, aspira-tion, initiation of rehabilitation intervention were the risk factors for poor outcome of swallowing function in all the patients, while the score of MBI was the protective factor for the pseudobulbar paralysis ones. Conclusion The younger the patients, the less the NIHSS score, no in-tubation, no aspiration, and the earlier the rehabilitation intervened, the more independent the pseudobulbar paralysis patients, the better swallowing function recovered.

Objective To investigate the effect of intensive education among the families on nutritional status of the stroke patients with dysphagia. Methods 42 stroke patients with dysphagia diagnosed with Standard Swallowing Assessment were enrolled in the study. The patients and their families were randomly divided into intervention group (21 pairs) and control group (21 pairs). The families of the intervention group were given the intensive health education, 5~10 minutes each time, once a week for 1 month. The families of the control group were only given routine health education. The two groups of patients received conventional drug and swallowing function training. Hemoglobin (Hb), serum albumin (ALB), contralateral brachial triceps skin fold thickness (TSF) and arm muscle circumference (AMC) were measured 1 month latter. Results Hb, ALB, TSF and AMC in the intervention group were higher than in the control group (P<0.05). Conclusion Intensive education among the families may improve the nutritional status of stroke patients with dysphagia.

In order to enhance the antitumor efficacy of recombinant Newcastle disease virus, rNDV-IL15 was rescued in this study. Recombinant plasmid prNDV-IL15 was constructed, and BHK21 cells were transfected with the recombinant plasmid. Finally, the recombinant Newcastle disease virus rNDV-IL15 was successfully rescued. The growth curves of these two recombinant viruses were determined. Murine melanoma B16F10 cells were infected with rNDV-IL15 at MOI of 0.1, and the expression level of IL15 in the supernatant was detected by ELISA. The antitumor efficacy of rNDV-IL15 and rNDV was compared in vitro and in vivo. Results showed that prNDV-IL15 was constructed and recombinant virus rNDV-IL15 was successfully rescued. The growth curve of rNDV-IL15 showed that the growth of rNDV-IL15 had not been changed after insertion of IL15 gene. Results showed that there was high level of IL15 expression in the supernatant of rNDV-IL5-infected B16F10 cells (1 044.3 +/- 27.7 ng x mL(-1)). rNDV-IL15 and rNDV significantly inhibited the growth of B16F10 cells in vitro in a time-dependent manner. However, there was no significant difference between them. In animal experiments, rNDV-IL15 efficiently suppressed tumor growth in vivo when compared with rNDV, and the difference was statistically significant. The results suggested that rNDV-IL15 is a more effective antitumor agent.

Fear memories are temporarily suppressed after repeated retrieval, a phenomenon known as memory extinction.How to reduce or even eliminate fear memory is the key to the treatment of fear related diseases such as post-traumatic stress disorder(PTSD). A single extinction training based on Pavlov's fear regulation task could only inhibit the expression of conditioned fear memory traces, but it could not eliminate the acquired conditioned fear memory. However, according to the reconsolidation theory based on memory, the retrieval-extinction paradigm has a more lasting effect on the erasure and rewriting of fear memory, and can effectively prevent the return of fear memory. Studies have shown that extraction-regression is closely related to a variety of neurotransmitter receptors such as glutamate receptor(GluR), dopamine receptor(DAR), L-type voltage-gated calcium channels(LVGCs) and cannabinoid. Moreover, its effect is closely related with factors such as retrieval-extinction memory stage. At present, most of the researches on extracted boundary conditions only stay at the level of behavior, with little understanding and exploration on the level of molecular mechanism. From the perspective of molecular neurobiology, with different stages of memory and different types of receptors and molecular mechanisms, this research reviewed the mechanisms of retrieval-extinction in recent years.It provided valuable signaling pathways, molecular targets and research directions for the treatment of fear-related diseases such as PTSD.
