2.The core value of internal responsibility for medical scientists
Chinese Medical Ethics 1994;0(05):-
The core values of internal responsibility for medical scientists include honesty?scepticism?fairness?collegiality and openess,et al.It's very important to discuss these guildelines,because they can regulate the behaviors of medical scientists and can also maintain the reputation of medical science.

Chinese Medical Ethics 2001;(2):6-7
Medication should follow the ethical principles of safety,efficiency,economy and individual.According to the principles and connection with current clinical practice,it has requirements for medical worker to be familiar with toxicity and side effect,(of) drug to observe the reaction srictly after patient taking drug and also to decrease the quantity and kind of drug in the whole way,rationally to carry out medicine compatibility and moreover to select rational way of drug taken and alleviate injury for patients etc.

OBJECTIVE: To investigate ultrastructurally into traumatic avascular necrosis of femoral head. METHODS: Femoral heads were procured during endoprosthetic replacement for 8 cases of intracapsular fracture of femoral neck, which had been subjected to internal fixation and developed Stage II avascular necrosis. The specimens were processed and studied under transmission electron microscope. RESULTS: In the normal bone tissues of the avascular necrotic femoral heads, the collagen fibrils constituting the collagen bundles of the bone matrix were of uniform diameter, and were regularly arrayed with orientation. In the necrotic bone tissues of the avascular femoral heads, the collagen fibrils were of unequal diameter, and were haphazardly arrayed without orientation. From the trabeculae of the avascular femoral heads emerged three different conditions of osteocytes: (1) In the trabeculae of normal bone tissues, the osteocytes belonged to both degenerative phase and formative phase osteocytes with the latter showing signs of degeneration; (2) In the necrotic trabeculae, the osteocytes perished leaving behind empty lacunae; (3) Over the trabeculae of the interface region could be discerned many active osteogenic cells, which were on their way of transformation into osteoblasts. In the trabeculae here, the osteocytes belonged to both formative phase and degenerative phase osteocytes. CONCLUSIONS: These results suggest that in the femoral heads with traumatic avascular necrosis, there is active osteogenetic activity around the necrotic bone tissues, amply implying a local reparative response following partial bone necrosis.

OBJECTIVE: To investigate further into the osteogenic potential of rabbit dermal fibroblasts with scanning electron microscope. METHODS: Split-thickness rabbit skin was processed into small chips that were cultured in vitro and then subjected to scanning electron microscopic study. RESULTS: The fibroblasts swam out from the skin chips and they increased in number rapidly and became confluent. The cells exhibited squamous configuration, possessing arboreal bifurcation and forming multi-layer structure. The fibroblasts then excreted numerous minute granules, heaping up on and around the cells. Thenceforth emerged on the cell surface fine needle-like crystals, that agglomerated with the granules to form nodules. The fibroblasts orientated themselves in a radiating pattern around the large nodules. Neighboring nodules could be linked up into trabecular structures. CONCLUSIONS: Sequence of events of new bone formation by rabbit dermal fibroblasts cultured in vitro is fully depicted and confirmed.

Objective: To establish a RP HPLC method to determine the content of adenosin in safflower Injection. Methods: The sample was determined by RP HPLC with a Diamonsil TM C 18 column, UV detection wavelength was at 270nm. adenosin used as an external standard and CH 3OH 1% HAC as a mobile phase. Results: The average recovery was 101.86%, RSD was 1.34%. Conclusion: The method is simple and accurate. It can be used to control the quality of Honghua Injection.

Objective To understand the status of soil?transmitted nematode infections in Xiding Township,Menghai Coun?ty,Yunnan Province,so as to provide the reference for formulating the strategy of soil?transmitted nematodosis control. Meth?ods Soil?transmitted nematode eggs in feces were detected by the Kato?Katz method,and the eggs of Enterobius vermicularis were detected by the cellophane tape method in children. The soil samples were collected from vegetable ,fruit and other crop fields of 15 residents randomly to detect hookworm. Results The stool samples from 1 002 residents were examined and the soil?transmitted nematode infection rate was 20.06%(201/1 002). The infection rates of hookworm,Ascaris lumbricoides and Trichu?ris trichura were 18.96%(190 cases),1.70%(17 cases)and 0.90%(9 cases)respectively. The percentages of people with light infection of hookworm,A. lumbricoides and T. trichura were 97.37%(185/190),88.24%(15/17)and 100%(9/9)respec?tively. No infection of E. vermicularis was found. Fifteen soil samples were tested,and no hookworm was found in the soil. Con?clusion The infection rate of soil?transmitted nematode in Xiding Township,Menghai County is high,but the infectiosity is light. The control and monitoring of soil?transmitted nematodosis should be strengthened in this area.

Objective To assess whether propofol call induce stable psychic dependence in the rats by self-administration experiment. Methods Twenty-four male SD rats 14 weeks old weighing 240一270 mg were studied. Anesthesia was performed with intraperitoneal injection of 3%sodium pentoharbitsl 40 ms/kg and atropine 03 mg/kg.A catheter wag inserted into the right external jugular vein. Penicillin(100 000 U)0.2 ml wag injected through the external jugular vein for anti-infection and heparin sodium(50U/ml)0.1 ml for anticoagulation. The self-administration experiment of 14 days was started after the 7 days of recovery. All the rats were randomly divided into 4 groups(n=6 each):contontrol group(C),propofol 0.56 mg/kg/l group(P1),propofol 1.00 mg/kg group(P2)and pmpofol 1.70 ms/kg group(P3).The experimental events were controlled by a computer with 50 times of the maximum injection per day.The times ofactive and inactive nose-poke response and times of drug iniection were recorded per day.Results Compared with group C and P1,the times of active nosepoke response and injections were significantly increased in group P2 and P3(P<0.01).The times of active nosepoke response and injections per day were significantly increased in group P3 than in group P2(P(0.01).There was no significant difference in the times of active nose-poke response and injections between group C and P1.There was no significant difference in inactive nose-poke resporme between the 4 groups.And the total daily doses of propofol injected in the last 3 days were significantly increased in a dose-dependent manner.Conclusion Propefol can induce the development of psychological dependence in rata and it is related to the dosage.

Objective To explore the association between serum amyloid A (SAA) and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitus(T2DM).Methods A total of 148 diabetic subjects were divided into three groups according to C1MT:normal IMT group,IMT incrassation group and arteriosclerosis group.Levels of SAA,25-hydroxyvitamin D [25 (OH) D],brachial-ankle artery pulse wave velocity (baPWV),high density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1 c),triglyceride (TG),total cholesterol (TC),body mass index (BMI) and blood presure were measured in all groups.The relationship between SAA,CIMT,25 (OH)D,baPWV and other factors was also analyzed.Results Compared to the normal IMT group,levels of FPG,HbA1 c,TC,BMI,SAA and ba-PWV were significantly higher in IMT incrassation group and arteriosclerosis group,while HDL-C and 25 (OH)D were lower.In arteriosclerosis group,levels of BMI,FPG,HbA1 c,SAA and ba-PWV were higher than those in IMT incrassation group,while 25 (OH) D was lower.Pearson correlation analysis showed that the level of SAA was positively correlated with baPWV,BMI,TC,course of disease and IMT,while it was negatively correlated with HDL-C and 25 (OH)D.Logistic regression analysis of IMT showed that smoking,obesity,high levels of HbAlc,FPG,TC,SAA,low levels of HDL-C and 25 (OH)D may contribute to higher levels of IMT.Conclusions SAA was closely related to carotid atherosclerosis.Further prospective studies will be helpful to explore the influence of SAA on diabetic macroangiopathy.
