Two famous historical events which lead to the establishment of the medical ethics committee are presented in this article. We discuss the significance of the medical ethics committee and put forward 5 propositions to enhance the developing of the committee. Firstly, overcome the scruple and accelerate the construction of the medical ethics committee. Secondly, seek for the ethics spirit from the traditional culture, and establish the principles and the conception correspondingly. Thirdly, be creative and try to adapt to the promotion of medicine and society. Fourthly, strengthen the training of bioethics. Finally, promote the communication between ethics review committees.

Objective: To improve the understanding of the clinical feature and early diagnosis of relapsing polychondritis(RP). Method: Eleven patients with RP were analyzed retrospectively and the reported literatures were reviewed. Result: Nine cases had initial involvement of auricular cartilage while two polyarthritis. The treatment of 2RP patients with respiralory tract involvement was invalid and 1 patient died. Nine cases were initially misdiagnosed, with a misdiagnosis rate of 81.82%. Conclusion: RP involves cartilage and connective tissue. The prognosis with respiralory tract involvement is poor. RP is a sort of paroxysmal and progressive inflammation involving cartilages all over the body with a variety of clinical manifestations. Early diagnosis of RP is based on full understanding of its clinical features.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

Objective To explore the risk factors of urolithiasis incidence of migrant workers in Zhongshan,in order to provide the scientific evidence for preventing urolithiasis.Methods 1 630 workshop migrant workers and 1630 office white collar workers were selected as the subjects of this study.The questionnaire was conducted according to the age,gender,genetic factors,occupation,past illness factors,living environment,work environment factors,diet habit,the habit of drinking water survey,B ultrasound examination,the detection of blood uric acid.Results The incidence rate of urolithiasis was 6.53％,the incidence rate of workshop migrant workers was 8.28％,which was significantly higher than that of white collar 4.72％ (x2 =16.972,P ＜0.01).Conclusion Work environment,eating habits,drinking habits,smoking and sweating are related risk factors of urolithiasis.

OBJECTIVE: To explore a method for locating the area of lacrimal sac in dacryocystorhinostomy under endoscopy. METHOD: Sixty-eight patients were performed dacryocystorhinostomy under endoscopy. Take light spot of ocular optic fiber as the lacrimal sac projection to the lateral wall of the nasal cavity position. RESULT: With the guiding of ocular optic fiber, lacrimal sac can be located accurately. The operating time of dacryocystorhinostomy under endoscopy was shortened significantly, and the operation procedure was simplified. All patients were followed up for 2 years, only 2 recurrent cases were found. The success rate reach to 97.06% (66/68). CONCLUSION Ocular optical fiber used in locating the lacrimal sac in dacryocystorhinostomy under endoscopy is simple and feasible, and can be widely used.

Objective :To explore influence of acupuncture combined butylphthalide soft capsule on cognitive function and head MRI imaging in patients with vascular dementia (VD).Methods : A total of 94 VD patients treated in our hospital were randomly and equally divided into butylphthalide group (received butylphthalide soft capsules ) and combined treatment group (received acupuncture pericardial acupoint treatment based on butylphthalide group ) ,both groups received controls of blood pressure and blood lipids ,anti—infection intervention ,and continuously treated for eight weeks .Mini—mental state ex—amination (MMSE) and clinical dementia rating scale (CDR) were used to assess cognitive function ,related head MRI in—dexes ,plasma levels of somatostatin (SS) and arginine vasopressin (AVP ) were measured.Results : Compared with bu—tylphthalide group after treatment ,there was significant rise in total effective rate (78.72% vs.93.62%) , P＝0.036 ;sig—nificant rise in MMSE score [ (19.18 ± 3.24) scores vs.(21.15 ± 4.11) scores] and significant reduction in CDR score [ (1.51 ± 0.26) scores vs.(1.37 ± 0.28) scores] , P＜0.05 both ;MRI indexes :significant reduction in width of three brain ventricles [(1.12 ± 0.13) cm vs.(1.03 ± 0.19) cm] ,and significant rise in anterior angle index [ (3.08 ± 0.96) vs. (3.54 ± 0.85)] and lateral brain ventricle body width index [ (3.19 ± 0.18) vs.(3.32 ± 0.21)] ,P＜0.05 or ＜0.01 ;sig—nificant rise in plasma levels of SS [ (133.59 ± 10.11) pg／ml vs.(139.14 ± 10.56) pg／ml] and AVP [ (35.37 ± 9.12) pg／ml vs.(40.25 ± 8.08) pg／ml] in combined treatment group , P＜0.05 or ＜0.01. There were no severe adverse reactions in either group .Conclusion : Acupuncture combined butylphthalide soft capsule can significantly improve cognitive function , plasma SS and AVP levels ,inhibit brain ventricle dilation ,promote brain function recovery in patients with vascular de—mentia ,and safety is high .

ABSTRACT:Objective To investigate the effect of PDCA nursing model in children with mycoplasma pneumonia.Methods 120 children with mycoplasma pneumonia treated with Tanre-qing combined with azithromycin were randomly divided into the observation group (PDCA nursing model)and the control group (usual care)with 60 cases in each group.Clinical compliance,effica-cy,clinical symptoms,hospitalization time and adverse reactions were compared in two groups.Re-sults The clinical compliance in the observation group was higher than that in the control group(P<0.05).The effective rate in the observation group was 98.33%,which was significantly higher than that in the control group(88.33%)(P <0.05).Cooling time observation group,cough time, rales disappeared time,tonsils congestion disappear time and length of hospital stay in the observa-tion group were significantly less than those in the control group (P <0.05).Incidence of adverse reactions in the observation group was 15.00%,which was significantly lower than that in the con-trol group(31.67%)(P <0.05).Conclusion PDCA nursing model significantly improves compli-ance and clinical efficacy in children with mycoplasma pneumonia,and shortens the time of clinical symptoms and hospitalization and reduces adverse side effects.
