The informed consent is the principle of medical ethics with which all the doctors in hospital should consistently comply in their medical therapy. Particularly in operation therapy, it is so important for doctors to insist on this medical ethics principle which embodies the specific principle for patients' dectisions for themselves. This accords with the general norm of medical ethics that patients are respected by the hospital. This principle is the morality requirement for operation therapy, and also one of the important measures for effectively reducing and avoiding medical disputes.

Objective To assess the role of various factors in the sterilization effect of ozone in water and provide the basic data for the correct use of ozone generator. Methods E.coli 8099 was employed as the indicative bacteria. The effect of killing E.coli 8099 by ozone in water was detected under various conditions,such as temperature,pH value,flux. Results The inactivated rates of indicative bacteria were 99.99%～100% by ozone in five minutes under the basic condition of 20 ℃,pH=7.0 and ozone flow of 1 L/min. The bactericidal effect was relatively better at low temperature and low pH value,the high flow of ozone led low sterilization effect of ozone. Conclusion High temperature,higher pH value,higher flow is not conducive for ozone to be dissolved in water,thereby will affect the bactericidal effects of ozone.

ObjectiveTo assess the effect of modified minimally-invasive transverse-vertical epicanthoplasty in double-eyelid plastic with three points at the same period.Methods87 cases with mild or moderate epicanthus and oriental eyelid were involved in our research.Epicanthoplasty was performed based on the principle of transversevertical plasty.The curvilinear incision of epicanthoplasty was made between the desired point of the new medial canthus and the lower lacrimal point,the malpositioned orbicularis oculi muscle excised after skin undermining,the superficial head of the medial canthal tendon plicated or anchored to the lateral nasal aponeurosis and the incision closed after skin redraping.Double-eyelid plastic with three points was performed as usual,however,the incision of eyelid plastic was connected with the incision of epicanthoplasty by skin tunnel in which a strip of orbicularis oculi muscle was excised.Results87 cases were followed-up for 3 to 24 months.The cosmetic results of the new medial canthi were satisfactory with new figure and inconspicuous scar.The contours of the double eyelids were natural.No incisional scar presented between the medial canthi and the upper eyelids.No recurrence of epicanthus was observed.ConclusionThe modified mini-incisional transverse-vertical epicanthoplasty together with double-eyelid plastic with three points is a simple and effective feasible surgical approach for correction of epicanthus and oriental eyelid.

ObjectiveTo observe the effect of mycophenolate mofetil(MMF) on systolic pulmonary arterial pressure (SPAP), right ventricle index (RVI), cytokines, receptors of pulmonary artery hypertension (PAH) rat models. MethodsThe rat models of monocrotaline (MCT)-PAH were developed. Thinty-two Sprague-Dawley male rats were divided randomly into four groups: the control group, the MCT, the MCT +low-dose MMF (20 mg·kg-1·d-1, MMF 20) and the MCT + high-dose MMF(40 mg·kg-1·d-1, MMF 40).There were eight rats in each group. SPAP, RVI, cytokines and receptor in the serum and lung tissue were measured in all rats. Comparisons between multiple groups were performed with q test and rank sum test.Results① Low-dose and high-dose MMF group were compared with the MCT group, SPAP[(40±13),(53±10) vs (68±10) mm Hg]and RVI(0.36±0.06, 0.38±0.03 vs 0.44±0.05) were reduced and showed statistically significant difference respectively(P＜0.05). (②) Compared with the MCT group, basic fibroblast growth factor(bFGF) of serum in both low-dose and high-dose MMF group were reduced and showed statistical difference respectively[(2.3±1.9), (2.7:t±1.3) vs (6.9±5.4) pg/ml, P＜0.05]. ③ Low-dose and high-dose MMF group were compared with the MCT group and showed that MA was decreased and the musculization of arterial wall was improved. ConclusionMMF can reduce SASP, RVI, number of MA. The inhibitory effect of MMF in PAH is possibly by inhibiting cytokines and receptors.

Objective The aim of this study was to detect the serum 25-hydroxyvitamin D (25-OH-D)and anti-vitamin D levels in new cases of systemic lupus erythematosus (SLE),and to investigate their clinical significance.Methods Fifty patients who fulfilled the ACR criteria for the classification of SLE and 36 healthy donors were included.Enzyme-linked immunosorbent assay was performed for serum 25 [OH] D and anti-vitamin D level measurement.Statistical methods used were t-test and Pearson's correalation analysis.Results The serum 25-OH-D level in SLE was (13±6) ng/ml,and the level in healthy donors wase (17±8)ng/ml,P =0.007); the difference was statistically significant.A significant negative correlation was demonstrated between the serum level of vitamin D and the 24 h urinary protein excretion (r=-0.314,P＜0.01),and the level of serum creatinine (r=-0.322,P＜0.01).Anti-vitamin D antibody was detected in 6 of 50 patients with SLE,in 10 of 36 sera from healthy donors.There was no difference of 25-OH-D level between the anti-vitamin D antibody positive group and anti-vitamin D antibodu negative group [(13±6) and (14±6) ng/ml in the SLE group; (17±6) and (18±9) ng/ml in the healthy control group].Conclusion The serum 25-OH-D level in SLE is low; however,it is not correlated with Anti-vitamin D antibody,but is correlated with renal lesions.So the serum 25-OH-D level may be important in the pathogenesis of SLE.
