Physiology is one of the most important elementary subjects for medical students.Associated with physiological teaching practice,some experience is shared here to further improve teaching effect.

Through the comparative analysis of traditional medical dispute handling methods and the concept of the third party mediation in medical dispute,this paper discussed that the third party mediation method in medical dispute obtain the recognition of both doctor and patient with its advantages such as neutrality,impartiality,convenience,and it had good running effect in the practice from place to place.But there still remain Some Problems,in cluding the intervention lacks initiative;the amount of indemnity lacks scientificity;the conciliation agreementlacks coercive enforcement;the privacy lacks protection;the institution development is limited.So we must improve the third party mediation work mechanism,identification process,operation mechanism and the relevant insurance system.

Hereditary disease, especially monogenic disease is one of the major causes for malformation and disability of children. Most hereditary diseases have no effective therapy besides clinical symptomatic treatment. Biological techniques targeting casual genes or related signaling genes, such as transgenic, RNA interfere, genome editing, have been successfully applied in treating some hereditary diseases. However, most biological, treatments were carried out in animals, further confirmation of the effectiveness and safety of these therapies, and development of more therapeutic approaches based on mechanisms are needed before clinical trials.

Objective To research the precise location algorithm of onset and end of one wave for QRS in ECG. Methods During monitoring the ambulatory electrocardiograph (AECG),it was necessary to design new automatic analysis algorithms. The windows formed by filtering and integrating process could be considered as the fiducially mark. From the window,the apex of Q wave and S wave could be recognized. Results Introducing an auxiliary line from the apex,we could judge the boundary of the Q and S wave with the distance from ECG curve to the line. Conclusion Many cases studies inelicate that the algorithm is of low level locating error,about one sample point,and the accuracy of judgement of S wave boundary is raised obviously compared with the same kind of software in the world.

Objective To investigate risk factors for hepatic steatosis in patients with chronic hepatitis B (CHB). Methods One hundred and eighty patients with biopsy-proven chronic hepatitis B were included in the study. Those with liver steatosis (61 from 93 cases) and those without it (61 from 87 cases)were matched on gender and age ( ± 3 years). Results Body mass index (BM I) was significantly higher in case group (24 ±3) than that in controls (22 ±3) (P ＜0.01 ). No significant difference was found in fasting plasma glucose, total cholesterol, triglycerides, urine acid, alanine aminotransferase, glutamyl transpeptidase and hepatitis B virus ( HBV ) DNA between the cases and controls ( all P ＞ 0. 05 ).Conditional logistic regression analysis with proportional hazard regression model statement by SPSS software showed that BMI was the only independent correlate to liver steatosis in patient with CHB ( OR = 1. 488, P ＜0. 01 ). Conclusions Liver steatosis in patients with CHB associates with BMI of the hosts, but does not correlate to their HBV DNA level.

Objective To investigate the dynamic changes of osteopontin (OPN) in the guinea pig model of cholesterol gallstone disease.Methods Forty-four guinea pigs were randomly assigned to cholesterol gallstone group and control group.The animals were sequentially killed on Day 7,14,28,42,56 and 70 after operation.The expressions of OPN mRNA in gallbladder and liver tissues were detected by real-time PCR.The changes of OPN,mucin,α1-acid glycoprotein (AAP) and apolipoprotein A1 (APOA1) in bile and blood plasma were detected by ELISA kits.Results The expression of OPN mRNA in gallbladder and liver tissues increased gradually and reached the peak in the 6th week,and then decreased.The increased expression of OPN in bile in the gallstone group started from the 1st week and reached the peak in the 6th week (P ＜ 0.05),which gradually decreased to the baseline in the 10th week (P ＞ 0.05).The expressions of OPN in bile and blood demonstrated similar trends,while the peak time in blood samples was much earlier (4th week).The changes of APOA1 in bile and blood were similar to OPN,although there was no advanced peak value in blood.The levels of mucin and AAP in bile and blood increased after operation,and were kept at high level throughout the study.Conclusions OPN is involved in the whole process of cholesterol gallstone formation,which may be associated with other nucleation-active factors.

Objective To investigate the effect of electroacupuncture at Shenting (DU24) and Baihui (DU20) on learning and memory ability, as well as the nerve cell and the expression of mRNA of Bcl-2 and Bax in the hippocampus of rats with cerebral ischemia/reperfusion (I/R) injury. Methods 45 male Sprague-Dawley rats were randomly diveded into sham group (n=15), control group (n=15) and electroacupuncture group (n=15). The latter 2 groups were modeled with middle cerebral artery occlusion for 2 h and reperfusion. The electroacupuncture group received electroacupuncture at Shenting and Baihui for 7 days. They were tested with Morris water maze, and then, their hippocampus was observed under Nissl staining and the level of Bcl-2 and Bax mRNA were determined with RT-PCR. Results The escape latency decreased (P<0.001) and the frequence the platform was crossed increased (P=0.001) in the electroacupuncture group compared with the model group, with less damage of the nerve cell and the expression of Bax mRNA, and more of Bcl-2 mRNA (P<0.05). Conclusion Electroacupuncture can prevent learning and memory ability from cerebral ischemia/reperfusion injury in rats, which may associate with adjustment of expression of apoptosis-related gene to inhibit apoptosis of nerve cell.

Objective To compare the differences of salivary alpha(α) amylase (sAA) activity and its activity ratio from the sali‐va before and after citric acid stimulation and approach the correlations among sAA activity determined by the methods of iodine‐starch ,Bernfeld and EPS‐G7 velocity respectively .Methods Ten saliva samples were collected from five healthy volunteers before and after citric acid stimulation .Their activities were determined three times by the three methods ,and the variation coefficient (CV) of sAA activity and activity ratio were calculated .Moreover ,correlation among sAA activities determined by the three meth‐ods were analyzed .Results The significant differences (P< 0 .05) were found in sAA activity and total CV from three determined methods ,and sAA activity and total CV by the method of EPS‐G7 velocity were minimum .There were no significant differences (P> 0 .05) in sAA activities ratio and its CV ;Significant correlation was found between sAA activity determined by random two of three methods(P < 0 .05) ,and their correlation coefficients were above 0 .96 .Conclusion The sAA activity data determined by three methods could be transformed each other by regression equation ,and determined precision by the method of EPS‐G7 velocity is highest ,and data processing method of sAA activity ratio could decrease differences among CV from three methods .

Objective:To assess the association between preoperative neutrophil–lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and red cell distribution width (RDW) and the tumor pathological features in gastric cancer (GC) patients. Methods: We re-viewed the records of 434 patients from 2012 to 2014 in Fujian Cancer Hospital. All patients were admitted to the hospital for the first time, and no patients received any cancer-specific pretreatment. For comparison, 309 age-and gender-matched healthy individuals who underwent annual physical examination at the hospital and 342 patients with chronic atrophic gastritis were enrolled. Results:GC patients had higher NLR, PLR, and RDW than the controls (P<0.000 1). Elevated NLR, PLR, and RDW were associated with the develop-ment of tumor stages as indicated by the Kruskal-Wallis analysis. However, no similar association was observed between the tumor dif-ferentiation grade and location and those three markers. Multivariate regression analysis further revealed that both NLR and PLR were independent predicting factors for either the tumor TNM or T stage (P<0.000 1). ROC curve analysis showed that NLR and PLR had a certain diagnostic effect on the preoperative T staging of GC. Conclusion:The preoperative NLR and PLR levels are closely correlated with the tumor TNM stages in GC patients. Both these parameters have potential values as markers to assist either in early diagnosis or preoperative tumor stage evaluation in GC.
