This article discusses the ethical problems which appear when medical laboratory technicians deal with all kinds of interpersonal relations in the field of medicine from the point of present medical service.It advocates that medical staff should possess professional morality and the sense of duty and calls for humane spirits to set up a brand-new mode of medical ethics.

Chronic kidney disease is closely related to inflammation. Chinese materia medica (CMM) or their extracts can intervene in some signal transduction paths such as nuclear factor-kappa B (NF-κB) path, mitogen activated protein kinase (MAPK) path, Toll-like receptor 4 (TLR4) path, and regulate cytokines, adhesion molecules, transcription factors, acceptor molecules, and enzyme molecules to resist inflammatory injury of renal tissue from multiple target points. Because of the interaction, network, and magnification of inflammatory injury factors, the action of CMM shows the characteristics, such as multi-point, pleiotropy, overlap, and so on. The target points of CMM on inflammatory injury are explored and their molecular mechanism plays an important role in the prevention and control of chronic kidney disease and study on new drug.

Objective To observe the value of the high frequency color Doppler uItrasonography in emergency operation of flexor tendon injuries in the hand.Methods Totally 21 patients of flexor tendon injuries in the hand underwent surgical exploration with high frequency probe.The extent of the tendon injuries,the retracted parts of the ruptured tendon and the blood supply were observed.Results The extent of the tendon injuries,the poison of broken ends were clearly distinguished with high frequency probe.The continuous tendon fibrous of layered high echo and sheath thin layer low echo complete broke and replaced with low or no echo.Conclusion Intraoperative uhrasonography of flexor tendon iniuries is important tO shorten operation time,reduce the injury of surrounding tissues,relieve local adhesion and ensure vascular recanalization after operation.

In this paper, we expatiate the advance of Tricholoma matsutake including distributing, environment, pure culture, domesticating cultivation and artificial forcing breeding in the area of Changbai Mountain of China.

Objective: To investigate the effects of taurine on blood glucose, number of platelets in plasma, pletelet aggregation and metabolism of oxygen free radicals in diabetic rats. Methods: Diabetes was induced by a single injection (ip) of streptozotocin (STZ,70 mg/kg body weight). The rats were maintained on drinking water with or without taurine (1.5 g/kg body weight per day). The concentration of blood glucose, maximal aggregation rate of platelets induced by adenosine 5 diphosphate(ADP) or thrombin(Thr) and the number of platelets in plasma were measured. Metabolism of oxygen free radicals in platelets was assessed as superoxide dismutase(SOD) activity and content of malondialdehyde(MDA) in platelets. [WT5FZ]Results: [WT5BZ]The concentration of blood glucose and maximal aggregation rate of platelets induced by ADP or Thr were significantly higher in diabetic rats than in non diabetic rats. The diabetic rats showed decreased platelet number and SOD activity with higher MDA level. In taurine treated diabetic rats concentration of blood glucose was obviously decreased, but no significant change was found in platelet number, SOD activity, MDA content and aggregation of platelets induced by ADP or Thr. [WT5FZ] Conclusion: [WT5BZ]There is a correlation between the increase in platelet aggregability and the abnormal metabolism of oxygen free radicals in platelets and taurine can decrease the blood glucose level but has no significant effect on platelet aggregability and metabolism of oxygen free radicals in diabetic rats.

OBJECTIVETo investigate the CT scan findings of primary pulmonary non-Hodgkin's lymphoma (PPNHL) and their relation to pathological features.

METHODSThe CT scan findings of 17 PPNHL cases confirmed pathologically from August 1992 to June 2007 were analyzed in relation to their pathological foundation.

RESULTIn 17 cases the CT findings showed: 1) Five were single mass or nodule, including 3 with air-bronchograms, 1 with straddling-lobe distribution and 3 with slight enhancement; 2) One was multi-nodules with air-bronchograms; 3) Six were consolidation with air bronchogram,including 3 with straddling-lobe distribution and 3 with slight enhancement; 4) Five were combined changes, including 5 with air-bronchograms, 2 with straddling-lobe distribution and 4 with slight enhancement. The CT features of PPNHL corresponded to their pathological process and pathological features.

CONCLUSIONPrimary pulmonary non-Hodgkin's lymphoma should be considered when CT scan shows variety of images found in one patient, middle lobe of right lung involved, air-bronchograms and straddling-lobe distribution in consolidation with slight enhancement.

Objective To observe the sensitivity of myocardium to ischemia/reperfusion (I/R) injury in mechanical trauma rats.Methods The mechanical trauma was established by Noble-Collip drum in the rats that were completely randomized into five groups:sham trauma group,trauma group,sham trauma and sham surgery group,sham trauma and I/R group,trauma and I/R group.The rats were subjected to 30 minutes of ischemia and one hour of reperfusion one week after trauma.The left ventricular systolic pressure (LVSP) and the left ventricular maximum rate of pressure rise and fall ( ± dp/dtmax ) were recorded with BL-410 biological signal recording and analysis system.The levels of serum creatine kinase isoenzyme MB (CK-MB) and cardiac troponinⅠ (cTnI) were detected by double antibody sandwich ABC-ELISA technique.At the end of reperfusion,the heart was excised and stained with Evan' s blue dye and triphenyltetrazolium chloride (TTC) to measure the infarct region with Image-Pro Plus 6.0 image analysis software.Results Compared with the sham traumatic I/R group,the cardiac function in vivo was significantly decreased in the traumatic I/R group ( P ＜ 0.01 ).While the serum CK-MB [ (4 960 ± 588 ) ng/ml:(2 925 ± 426) ng/ml,P ＜ 0.01 ],cTnI [ ( 18.10 ± 3.06 ) ng/ml:( 6.67 ±1.57 ) ng/ml,P ＜ 0.01 ] levels and myocardial infarct size [ ( 36.70 ± 7.42 ) ％:( 22.27 ± 4.54 ) ％,P＜0.01] were obviously higher in the traumatic I/R group compared with the sham traumatic I/R group.Conclusion Mechanical trauma increases the sensitivity of myocardium to I/R injury in rats.
