Surface topography of the Anisakis type I 3rd stage larva (L3), the main pathogen of anisakiasis, was observed by scanning electron microscope under magnifications of 400 to 14000X. The head bears a trapezoid undivided lip mass, with 2 mammillary elevations at the middle of the two lateral sides and a cuticular boring tooth on its ventral side. The mouth leading into the esophagus is situated in the centre of the centrally located cuticular elevation of the lip mass. The excretory pore opens ventrally just behind the boring tooth. The surface of the lip mass shows fine striations, but looks smooth elsewhere. Neither flat papillae nor minute "teeth" or "hairs" described hither to have been observed. The cuticle of the body surface shows shallow and irregular annular grooves and folds and numerous fine longitudinal micro-furrows and cristae. These surface markings appear uniformly from head to tail and to the utmost end of the pagoda like mucrones at the tip of the tail. The ventrally located crescent anus is situated about 90?m from the base of the mucron.

Objective To investigate the clinical features and drug resistance of neonatal purulent meningitis caused by Escherichia coli. Methods The clinical data of 46 neonates diagnosed with purulent meningitis caused by Escherichia coli were retrospectively analyzed from June 2004 to June 2014. The neonates were divided into community acquired infection group and nosocomial infection group, or early group (from June 2004 to May 2009) and late group (from 2009 June to June 2014). Result Fever, hypothermia, lethargy, poor feeding, tachypnea, and tachycardia were common clinical manifestations in all neonates. The detection rate of ESBLs was signiifcantly higher in nosocomial infection group than that in community acquired infection group (P?0.05), and also was signiifcantly higher in the late group than that in the early group (P?0.05). The rates of resistance to commonly used cephalosporins were signiifcantly higher in nosocomial infection group than those in community acquired infection group. The rates of resistance to commonly used penicillin and cephalosporin were signiifcantly higher in the late group than those in the early group (P?0.05). Conclusions The clinical manifestations of neonatal purulent meningitis caused by Escherichia coli are not typical. The drug resistance rates of ESBLs to penicilins and cephalosporins are increasing recently. Nosocomial infection is the risk factor for ESBLs.

Objective To study the properties of K~ +-ion channel of rat parietal cells, and to approach its effects on physiological and pathological process. Method Parietal cells were isolated. Electrophysiological records of K~ +-ion channels were made through whole cell's patch clamp technique, and the properties of the channels were analyzed. Results 10mM tetraethylammonium chloride may partially block the outwardly depolarized K~ +-ion channel current. While 10mM tetraethylammonium acetate, 10mM barium chloride or 10mM barium acetate may increases the outwardly depolarized K~ +-ion channel current. Conclusion The whole cell K~ +-ion channel current of rat parietal cells showed voltage sensitive. The current-voltage relations of whole cell potassium channels of rat parietal cells are both outwardly and inwardly rectified.

To explore whether the imprinting status of IGF-2 in the malignant epithelial ovarian tumors is different from that in benign tumors, the target sequences (DNA and RNA) which contain a polymorphism site for ApaI restriction endonuclease digestion were amplified with PCR and RT-PCR methods. Then the PCR/RT-PCR products were digested by ApaI. The IGF-2 transcriptional pattern came out from the results of endonucleases digestion. Among the 36 cases of benign epithelial ovarian tumors, 20 were heterozygous for ApaI locus and all showed genomic imprinting. While in the malignant group, 22 were heterozygous for ApaI locus but six were found to lose imprinting. Significant differences existed between the two groups (P < 0.05). Loss of imprinting of IGF-2 may serve as a marker for differentiating the malignant ovarian cancers from the benign ones. In a new field of molecular genetics, our research provides an experimental basis for genetic diagnosis and treatment of the ovarian cancers.

OBJECTIVE To analyze the high risk factors and etiology character of ventilator-associated pneumonia(VAP) and provide the guidance for preventing VAP. METHODS Eighty three cases given mechanic ventilation over 48 hours in ICU of our hospital from Jan to Oct 2005 were observed.Thirty seven cases met the diagnosis criteria of VAP,while 46 cases without VAP were taken as control. RESULTS Airway secretion was cultivated and Gram-negative germ was the majority(58.0%).The first three pathogens were Pseudomonas aeruginosa(32.0%),Acinetobacter,and Staphylococcus epidermidis,22.0% cases had mixed infection with fungi.Except antiacid treatment,the following factors,such as long time for mechanical ventilation,trachea incision,corticosteroids treatment and coma state had significant relationship with the occurrence of VAP. CONCLUSIONS The occurrence of VAP is related with multiple clinical factors.Clinicians should reduce high risk factors to lower the occurrence of VAP.
