The rule of law is the basic approach of realizing harmonic relationship between doctors and patients.Therefore,the law on medicine and health should be consolidated,and the rights and obligations of both parties should be specified.Meanwhile,the enforcement of law should be strict and civilized,while developing the legal awareness of the people to maintain their rights legally,and creating nice medical sequences and doctor-patient relationship in legal environment.

Seventeen trace elements, including twelve essential trace element, and three normal elements in serum of 417 healthy students aged 7 to 20 in Shanghai were analysed. Except Se which was determined by catalytic pulse polarography, Zn, Cu, Fe, Mn, Cr, Mo, Si, Sn, Ni, V, Co, Cd, Pb, Al, Ti, Sr, Ca, Mg and P in serum were measured by ICP-AES. The result showed that the distribution curve of normal elements and Zn, Cu in serum was more concentrated than the other trace elements. There were significant positive correlation between serum Zn, Fe, Mn, Sr and age, and negative correlation between Cu, Cr, Se, Pb and age, respectively. The elements of males were the same as that of females in total population, but the majority of the elements in serum had sex difference in different age-groups. The serum Cr, Si, Pb contents were higher, and Cu, Fe, Mn, Sr were lower in the urban than in the rural adolescents.

Aim To investigate the effect on antagonism of benthiactzine and atropine against the function of muscarinic acetylcholine receptors by desensitization of nicotinic acetylcholine receptors. Methods The whole cell recording configuration of patch-clamp technique was used and the cell model was rat SCG neurons. To identify antagonists' antimuscarinic effect, mAchRs mediated IM-inhibition was measured and nicotine and oxotremorine were used. Results After de sensitization of nAChRs,the antimuscarinic effect ofboth benthiactzine and atropine decreased compared to the normal condition. The decreased antimuscarinic effect of benthiactzine was weaker than that of atro-pine. The antimuscarinic effect of both benthiactzine and atropine recovered gradually with the recovery of nAChRs from desensitization. Conclusion Desensiti-zation of nAChRs weakens the antagonists' antimuscarinic effect.

Objective To observe the clinical efficacy of traditional Chinese medicine foot bath combined with Xueshuantong injection in the treatment of diabetic peripheral neuropathy.Methods Sixty patients with diabetic peripheral neuropathy(DPN)were randomly divided into two groups.According to the patients' condition,oral hypoglycemic drugs or insulin were used to control blood glucose.The control group was treated with Xueshuantong injection on routine nutrition nerve program.In the conventional nutrition nerve program based on the use of traditional Chinese medicine foot bath combined with Xueshuantong injection treatment,2 groups were treated after 10 days to evaluate the efficacy.Results The total effective rate of the observation group and the control group was 90％and 66.7％respectively.The sensory and motor function of the observation group were significantly improved after the treatment group,and the blood rheology and serum endothelin level were significantly decreased.Conclusion Chinese medicine foot bath combined with Xueshuantong injection for the treatment of diabetic peripheral neuropathy.

Objective To investigate the clinical efficacy of Lu’s warm needling in treating perimenopausal syndrome.Methods Sixty patients with perimenopausal syndrome were randomly allocated to treatment and control groups, 30 cases each. The treatment group received Lu’s warm needling and the control group, conventional acupuncture. The scores of Kupperman Index (KI), Pittsburgh Sleep Quality Index (PSQI) and Hamilton Depression Scale (HAMD), and serum estrogen (E2), follicle stimulating hormone (FSH) and luteal hormone (LH) were observed before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 80.0% in the treatment group and 53.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the KI score in the two groups (P<0.01). There was a statistically significant difference in pre-/post-treatment KI score difference value between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in serum LH, FSH and E2 contents in the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the Hamilton Depression Scale score and the Pittsburgh Sleep Quality Index score in the two groups (P<0.01, P<0.05). There was a statistically significant post-treatment difference in the Hamilton Depression Scale score between the treatment and control groups (P<0.05).Conclusion Lu’s warm needling is an effective way to treat perimenopausal syndrome.

Objective To investigate the morphologic characteristics of neuron-like cells induced from the rat mesenchymal stem cells(MSCs). Methods The rat MSCs from bone marrow were cultured by being adhered to the culture dish.The thirdgeneration of the MSCs were induced by the neonate rat brain homogenate supernatant for 48 hours.The morphological characteristics and the ultrastructures of both non-induced and induced MSCs were observed under the inverted microscope and the electron microscope.The property of the induced cells was identified by using immunocytochemical method. Results Under the inverted microscope MSCs showed spindle or polygon-shaped cell bodies and the nuclei with one or two nucleoli were located in the middle of the cells.After the inducement the cells appeared neuron-like with axonlike and dendrite-like processes.The neuron-like cells were neuron special endolase(NSE),neurofilament protein(NF) positive and glial filbrillary acidic protein(GFAP) negative by irnmunocytochemical staining.Under the electron microscope the MSCs had plentiful cytoplasm and organelles and had an obvious nuclei containing a nucleoli.There were a lot of microvilli on the surfaces of the MSCs.The neuron-like cells had plentiful cytoplasm and irregular nuclei with one to three nucleoli.There were also plenty of microvilli on the cell surfaces.Conclusion MSCs are one kind of multipotent stem cells and can differentiate neurons with matured organelles induced by the neonate rat brain homogenate supernatant.

Objective To explore the feasibility of clinical application of biodegradable polymer-coated drug-eluting stent. Methods Thirty each of the drug-eluting stent or bare-metal stents were implanted randomly into the anterior descending arteries, circumflex and right canine coronary arteries of thirty healthy pigs. The pathological examination was taken at 2 weeks to 6 months after coronary angiography to investigate the inflammation, thrombosis and endothelialization. Results Macroscopic observation of the stented arteries demonstrated complete incorporation of stent wires into the arterial wall and smooth vessel lumens. There were no significant differences existing between two kinds of the stents in terms of thrombosis, inflammation and endothelialization. The lumen loss in the biodegradable polymer-coated drug-eluting stent group is less than that in the bare-metal stent group. Conclusion The biodegradable polymer-coated drug-eluting stent is promising with good biocom-patibility, blood compatibility and phyaicochemical stability after being implanted into pig coronary arteries. The blood vessel transplanted with the drug-eluting stents maintains a high patency rate due to rapid endothelialization.

Aim To investigate the desensitization characteristics of neuronal ?4?2、?4?4 and ?7-nicotinic acetylcholine receptors heterologously expressed in the SH-EP1 cell line stimulated by prolonged of repetitive application of agonist.Methods The Whole cell recording configuration of patch-clamp technique was used to study the desensitization characteristics of ?4?2、?4?4 and ?7-nAChRs in cultured SH-EP1 cells three days after passage by rapid application of nicotine onto the soma of the cells.Results Inward currents were elicited by rapid application of agonist in all the three types of SH-EP1 cells in a concentration-dependent manner.?7-nAChRs desensitized the fastest and deepest in the three while ?4?4-nAChRs the slowest and lightest under prolonged stimulation.?4?2-nAChRs desensitized the fastest in the three under repetitive stimulation while ?4?4 and ?7-nAChRs didn't have obvious desensitization.Conclusion When stimulated by prolonged of repetitive application of agonist,neuronal ?4?2、?4?4 and ?7-nicotinic acetylcholine receptors had different desensitization characteristics,which is possibly associated with their roles in organophosphate poisoning inducing persistent stimulation of excessive accumulation of endogenous ACh and in nicotine addiction inducing repetitive stimulation of nicotine.
