Plastic Bronchitis (PB) is a condition characterized by formation of plugs or casts in the tracheobronchial tree, which can induce partial or complete airway obstruction and ventilatory dysfunction.The clinical manifestations are nonspecific, usually including cough, progressive dyspnea and refractory hypoxemia.However, dyspnea and hypoxemia can be quickly improved by removing branching casts with bronchoscopy.Now, the the clinical features and differential diagnosis of PB are described in this article, in order to improve the diagnosis of the disease.

Objective\ The adrenal gland is a linkage between nervous system and endocrine system.Its cortex results from mesoderm,and medulla derives from neuroectoderm.Searching its double characteristic of nervous and endocrine tissue is our aim. Methods\ Histochemical and immunohistochemical staining techniques were used,and immunostained sections were observed under a light microscopy. Results\ NPY positive neuron and nerve fiber,CGRP positive nerve fiber existed in adrenal cortex.NADPH d positive neuron and nerve fiber, c fos positive neuron and nerve fiber,CGRP positive nerve fiber,SP positive nerve fiber were detected in adrenal medulla.NADPH d positive cell,NPY positive cell,CGRP positive cell,SP positive cell were found among the adrenal chromaffin cells.The zona glomerulosa,zone fasciculata and zona reticularis were stained strongly by NADPH d in cortex. Conclusion\ The adrenal gland was innervated by NO ergic,NPY ergic,CGRP ergic,SP ergic, c fos ergic nerves.The adrenal parenchyma,especially chromaffin cells can produce NO,NPY,CGRP,SP which regulate adrenal endocrine by itself.The nervous control of adrenal function and neuroendocrine function of adrenal gland is more complex than hitherto believed.\;

Objective Our purpose is to explore the occurrence and distribution of glutamate and metabotropic glutamate receptor in earthworm, P. aspergillum and to analyze their function significance. Methods By employing immunocytochemistry tchnique, the positive cells of glutamate and metabotropic glutamate receptor, mGluR1, mGluR2/3, mGluR4 in earthworm, P. aspergillum were investigated under a light microscope. Results It was found that glutamate positive cells existed in cerebroganglion, subpharyngeal ganglion, ventral ganglion, neurons between muscle cells,intestinal epithelium and epidermis, that thin and dense glutamate positive fibers distributed in pharyngeal nerve cycle, subpharyngeal ganglion, ventral neurochain, that mGluR1 or mGluR4 positive neurons were detected in cerebroganglion and mGluR2/3 positive neurons weren't observed in earthworm. Conclusion During glutamate positive neurons, some possess remarkable processes and matured appearance from which glutamate positive fibers in pharyngeal nerve cycle, subpharyngeal ganglion, ventral neurochain derive, another have few branches, unmatured appearance in which glutamate doesn't serve as neurotransmitter acting to mGluR1 or mGluR4 of neurons in earthworm cerebroganglion.

The field of rehabilitation medicine physical therapist (PT) training and education has been relatively weak links in China, how to build a rehabilitation therapist team, we constantly explore and get a greater progress. However, most of the time is still confined to empty the contents of most theoretical level, and some basic steps and the specific contents are lacked. How to stabilize therapists team? How to position therapists? It deserves to pay more attentions.

Gemcitabine is a new active drug in the treatment of advanced non small cell lung cancer (NSCLC). It is validated that the response rate of the single agent gemcitabine was consistently above 20%, median survival was 34 weeks and it could improve the disease related symptoms with well toleranced toxicities by many clinical studies. This report reviews the clinical studies of gemcitabine in the patients with advanced NSCLC.

Objective To evaluate the key role of development of medical and biological techniques correlating with medical protection against New Concept Weapons(NCWs) and put forward a development strategy in medical protection against NCWs. Methods Data on the present medical techniques protecting against NCWs were obtained by tracing references. On the basis of analyzing and studying the obtained data, an evaluation was made by consulting experts, system analysis, scientific selection, clustering analysis and policy analysis. Results The correlation coefficients correlation, indexes and scores in the present progress of 36 techniques were determined. Furthermore, the evaluation was made. Conclusion Different developing strategy should be taken in accordance with the important and the present research on medical and biological techniques correlating with medical protection against NCWs. This study will give us some advice on protecting against NCWs in medicine.

Objective The levels of endothelin-1(ET-1) and calcitonin gene-related peptide(CGRP) in the plasma and cerebrospinal fluid(CSF)after acute cervical spinal cord injury. Method ET-1 and CGRP were determined by RIA in order to observe the effects of naloxone on levels of ET-1 and CGRP and neuronal death of cervical spinal cord. Result Levels of ET-1 in the plasma and cerebrospinal fluid(CSF)after acute cerical spinal cord injury increased significantly; but the levels of CGRP in the plasma and cerebrospinal fluid(CSF) decreased markedly. The levels of ET-1 in the plasma and cerebropinal fluid(CSF)decreased markedly after the threapy of naloxone; but levels of CGRP in the plama and cerebrospinal fluid(CSF)increased sinificantly. Conclusion These deta suggest that the lessening of CGRP and increasing of ET-1 may be some important reson causing death of neuron after acute cervical spinal cord injury, and naloxone can protecet cervical spinal cord neuron by increasing levels of CGRP and decreasing levels of ET-1.

ObjectiveIn order to enhance the curative resectability rate of pancreatic carcinoma. MethodsSixteen consecutive patients received an extended resection, which is referred to systemic dissection of regional lymph nodes and combined resection of the diseased PV/SMV based on traditional Whipple operation or the distal pancreatectomy. ResultsMean operation time was 8.5 hours. Mean intraoperative blood infusion was 1250mL. The procedure was considered curative in 11 (68.8 % ) and palliative in the other five. Postoperative complications occurred in 7 (43.8% ). Perioperative death occurred in one patient(6.25% ). Median length of hospital stay was 35 days. In nine patients undergoing curative resection,two cases survived for 1/2～1 year, six patients survived for 1～2 year and another patient has survived for more than 32 months without evidence of recurrence. ConclusionExtended resection for pancreatic cancer is technically feasible and two- third of pancreatic carcinoma invading PV/SMV alone can be expected to obtain curative resecetion.

Chi-pulse diagnosis is a kind of pulse diagnosis by only feeling Chi part of pulse.This method focuses on inborn Yin-yang,fire-water,and growth and decline of kidney essence,emphasizes on the physiological and pathological changes of eight extra meridians and extra viscera,clarifies and expands the content of narrow sense of yin-yang method.Chi-pulse diagnosis is prone to guided by the spot pulse feeling,do not limited by regular pulse name,and has special pulse diagnose experience and fixed knowledge of formula prescription.
