Objective:To explore the relationship between false increase of white blood cell count and fragility of erythrocyte membrane in automatic whole blood count. Methods: The osmosis and incubation osmosis fragility of erythrocyte membrane in controls 1 (Group 1, n =30)and white blood cell count false increase (Group 2, n =30) were detected by the operation rule of the group of clinical examination. Results: Compared with the results of Group 1 frogility of erythrocy to membrane in infectious hepatitis,livercirrhosis and liver cancer were reduced( P

Objective To detect the double DNA of trisomy 21 syndrome patients by denaturing high-performance liquid chro-matography(DHPLC) in order to rapidly diagnose trisomy 21 syndrome .Methods To amplify DNA fragments of three short tan-dem repeats of D21S111 ,D21S1411 and D21S1412 using corresponding primers .Then DHPLC was introduced to analyze the DNA fragments in the temperature of 50 ℃ .Results DHPLC elution profiles of D21S111 ,D21S1411 and D21S1412 of normal control showed one peak or two peaks with the same altitude .However DHPLC elution profiles of 21 trisomy syndrome patients showed two peaks of different altitudes ,which one′s altitude was twice than another .Conclusion DHPLC is a sensitive ,convenient ,auto-matic and highly-efficient method to diagnose trisomy 21 syndrome and can be widely used in the clinic diagnosis .

Objective Traditional nasolacrimal duct stenting possesses some shortcoming including difficulty of pulling ball head guide wire from the nasal cavity with turbinate hypertrophy and nasal septal deviation. The new method of nose-oral tube track establishment can overcome the forementioned and increase the successful rate. Methods 5 F catheter and arterial sheath were modified to be nasolacrimal duct stent delivery device respectively. Antegrade dacryocystography was taken firstly to display the obstructed site and followed by the modified protocol of inserting the guide wire through nasolacrimal duct and nasal cavity, and establishing the stent delivery track for retrograde stent placement. Results 5 epiphora patients with failure implantation by traditional method were all succeeded through the modified stenting(100%). During 6-mouth follow-up, no serious complications and reocclusion occurred. Conclusion The establishment of eye-nose-mouth-nose of external nasal guide wire track can improve the successful rate of nasolacrimal duct stenting.

Objective To investigate the nursing points of the mechanical ventilated patients after percutaneous endoscopic gatrostomy (PEG). Methods The nursing approaches of 28 mechanical ventilated patients after percutaneous endoscopic gatrostomy in our department was analyzed retrospectively. Results The nutritional status of the 28 patients was improved to different degree after enteral nutrition (EN) support by PEG. Thereby, the nutritional requirement of the mechanical ventilated patients was ensured effectively. Among these patients, 4 patients could take food by mouth after taking off ventilator and extubation and stoma tube was pulled out, 15 patients were discharged carrying with stoma tube and convalescent care was continued, 3 patients died of primary diseases. Conclusions The PEG is a simple,safe and cost-effective approach of nutritional support for EN of mechanical ventilated patients. The key point of insuring EN of severe patients is intensive nursing and to prevent and reduce the complication of PEG.

Salinity is the main limitation factor for plant growth and crop production.Many approaches to enhance plant resistance to salinity by genetic engineering have been developed.Over-expressions of salt-tolerance related genes encoding proteins involved in signal transduction pathways,ion channels and compatible solutes synthesis for the stabilization of biological structures under salinity stress are the most often used strategies.The recent progresses in genetic engineering to improve salt tolerance in plants and the possible problems in researches was reviewed.
