猫颈部食管的交感神经支配—HRP法

用5只猫于左侧颈部食管壁内注入 HRP 溶液,通过 HRP 逆行追踪法研究颈部食管的交感神经支配,结果表明:1.长轴突型交感节前神经元直接分布到食管壁内,其标记细胞位于双侧脊髓的胸1～3节段,以胸2节段最多(占标记细胞总数的66.45％),注射侧占优势。标记细胞主要位于中间带外侧核(约占95.02%),其次为侧索、中介核、前角腹后外侧核。其细胞形态不一,以中小型细胞为主(占标记细胞总数的90.4％)。2.支配颈部食管的交感节后神经元主要位于星状神经节(约占61.99％),余者位于双侧颈前、中和2～5胸交感节内、以小细胞最多。     

Barotrauma in guinea pigs--stimulated tests of diving

For a systematic understanding of the effect of diving on hearing ability and middle and inner ear morphology, we have carried out simulated tests on 65 healthy guinea pigs, under water 60 meters deep, and then decompress rapidly. The tests proved that hearing ability changed most significantly 7 days after diving. After diving, all tympanogram curves, except those in 3 ears, changed to type B. Thirty-nine (37.85%) middle ears had been damaged, 4 (3.88%) had inner ears injured, as seen under light microscope. During decompression, three animals had nystagmus. Screen electronmicroscopy showed hair cell destruction and hair derangement. Transmission electronmicroscopy showed mitochondria damage. The results showed that damages in middle and inner ears were mainly mechanical, sometimes metabolic.

Intrathecal morphine for post-thoracotomy pain

We wished to investigate possible differences in the duration of postoperative analgesia and the incidence of respiratory depression after the intrathecal injection in the lumbar area of 10 micrograms/kg morphine in hypobaric and hyperbaric solution for relief of post-thoracotomy pain. Twenty-nine patients received morphine plus dextrose (hyperbaric) and 21 received morphine in preservative-free normal saline. The duration of analgesia was longer with the morphine in the normal saline group than in the hyperbaric group (P less than 0.04). One patient developed delayed respiratory depression. Our data support the use of morphine in normal saline mixtures for greater duration of analgesia after thoracic operations.

Kindergarten children's representation and understanding of written number symbols

Two samples of kindergarten children's representation and understanding of written number symbols were examined in two time points in one academic year. About 85% of Chinese five year olds (mean = 5 years 10 months) were able to use conventional number symbols to represent the quantity of 30 or larger. At the end of the kindergarten year, 94% of Chinese six year olds (mean = 6 years 4 months) were able to use conventional number symbols to represent the quantity of 100 or larger. Some Chinese six year olds had problems in representing written addition and subtraction tasks. Children's ability to represent written number symbols, ability to represent written addition and subtraction formula and their performance on written addition and subtraction were closely related. The performance of children in a university-affiliated childcare center was better than that of the center serving working-class families in Time 1, but the performance reversed at the end of the kindergarten year.     

甲基苯丙胺抗体、疫苗以及检测试纸研究进展

苯丙胺类兴奋剂(amphetamine-type stimulants,ATS)是21世纪主要流行滥用的药物之一,目前社会上流行的"冰毒","摇头丸"等属于此类毒品,主要有甲基苯丙胺(methamphetamine,METH),亚甲基二氧基甲基苯丙胺(MDMA)等.在我国,此类毒品无论是在舞厅、迪吧或其它公共娱乐场所和地下色情场所等都很容易获得,导致滥用人群日益扩大[1],影响社会治安和社会稳定.虽然世界各国在药物滥用防治工作中投入了大量的人力、物力、财力,但收效甚微,对ATS依赖者目前治疗多采用强制戒毒、对症治疗和辅以心理治疗等方法,但治疗时间长,复吸率高[1-4],对于高危人群目前还没有一种有效的预防手段.检测ATS多用高效液相色谱(HPLC)、气相色谱-质谱联用(GC-MS)、薄层色谱(TLC)等[2]方法,其设备昂贵,难以开展现场检测,应用范围受限,并不适合于现场快速便捷检测,因而探索对ATS更有效的预防、治疗方法和更便捷的现场检测方法,极具现实意义.     

Acute pancreatitis combined with acute Budd-Chiari syndrome as the initial manifestation of small cell lung cancer.

Tumor metastasis to the pancreas is a rare but recognized cause of acute pancreatitis. Autopsy series have reported a 24-40% of pancreatic involvement in small cell lung cancer. However, only a very few cases of tumor-induced acute pancreatitis have been described. Budd-Chiari syndrome complicating lung cancer is a rarely reported condition. We report a 68-year-old woman with extensive small cell lung cancer with the unusual initial presentation of both acute pancreatitis and acute Budd-Chiari syndrome. This patient suffered from progressive epigastralgia for 3 weeks. Severe epigastralgia with radiation to back and progressive jaundice developed 2 days prior to admission. After admission, the liver enlarged rapidly and the ascites increased markedly. Chest roentgenogram showed a mass lesion over the left lower lung field. Poorly differentiated carcinoma cells were found in ascites and bone marrow. The patient died on the ninth day of hospitalization before chemotherapy was initiated. Prompt diagnosis of extensive-stage small cell lung cancer may allow early chemotherapy treatment which favorably influences recovery when the pancreatitis is mild. Although prolonged survival might have been expected had this patient recovered from pancreatitis and received chemotherapy, diagnosis was delayed due to difficulty in immunohistochemical diagnosis of the tumor and the unusual clinical presentation. The use of stains employing antibodies against neurofilament and neuron-specific enolase cell antigens is important for early diagnosis of poorly differentiated metastatic tumor cells.
