Conflicts may occur between patients' independent decision right,family members' interference right,and medical interference right.This article clarifies the applicable premise of medical interference right and explores its realistic predicaments from the ethical and legal perspectives.Reasonable system construction is a good solution to medical disputes,promoting a harmonious development of physician-patient relationship.

The choledocho-pancreatico-duodenal junc-tion is located at the central part of choledocho-pancreatico-duodenal region. During early embryogenetic stage, the primary duodenum develops from the end of foregut and the beginning part of the midgut. The dorsal pancreas, hepatic diverticulum and the ventral pancreas which arises from the basic part of hepatic diverticulum are growing and rotating following the duodenum. During the course, the formations of the choledocho-pancreatico-duodenal region and the central part of choledocho-pancreatico-duodenal junction are complete. The injuries in cho-ledocho-pancreatico-duedenal junction may be caused by metal probe or lithotomy forceps for exploring, dilatating the distal bile duct or taking out the stones from the bile duct. Even if the injuries of choledocho-pancreatico-duodenal junction are deve-loped in a limited scope of several centimeters, several adjacent organs may be involved. Injuries in choledocho-pancreatico-duo-denal junction are hard to be identified during operation and may develop into serious pathological procedures.

Objective To invetigate clinical characteristics,pathogenesis and its risk factors of neuropsychi-atric lupus erythematosus(NPLE).Methods 160 cases of SLE patients,including 30 cases of diagnosed NPLE,were analyzed retrospectively.The relationship between the appearance of NPLE and common autoantibodies,other organ involvement and SLE disease activity score(SLEDAI)were analyzed.Results Such antibody positive rates of anti nuclear antibody(ANA),anti Sm antibody,anti -RNP antibody,anti SSA antibody,anti ds -DNA antibody had no significant difference between NPLE and non NPLE,the value of χ2 was 0.947,0.013,1.194,0.023,0.745 respectively,the value of P was 0.194,0.910,0.274,0.879,0.388 respectively.Renal involvement,raynaud phenomenon,interstitial pneumonia,pulmonary thromboembolism,oral ulcer,arthritis,facial erythema,pleuritis,pericarditis,fever,pulmonary hypertension,photo -allergy and alopecia in the two groups had no difference,the value of χ2 was respectively 0.419,1.383,0.721,0.201,1.368,1.194,0.055,0.946,0.262,2.503,0.628,2.898 and 0.075,the value of P was 0.517,0.324,0.396,1.000,0.242,0.274,0.815,0.331,0.609,0.114,0.428,0.089 and 0.785 respectively.But the occurrence of hand and foot vasculitis in NPLE was significantly higher(χ2 =3.996,P =0.046).SLEDAI of NPLE was higher than non NPLE(t =8.446,P =0.000).Conclusion There was no correlation with the occurrence of NPLE and common autoantibodies,other organ involvements.Hand and foot vasculitis and higher SLEDAI(more than 15 points)were the risk factors of NPLE.Encephalopathy may be the initial manifestation to some of SLE cases. Early diagnosis and methylprednisolone pulse treatment combined with immunosuppressive therapy can effectively improve the remission of the disease,reduce mortality and improve prognosis.

Objective To evaluate the effect of exogenous epidermal growth factor (EGF) on promoting nerve regeneration after terminolateral neurorrhaphy (TLN). Methods Thirty-two adult Wistar rats were randomly divided into 2 groups. In the EGF group,the left peroneal nerve was transected,then an 1mm epineural window was created on the neighbouring tibial nerve. The distal end of peroneal nerve was sutured to the windowed tibial nerve by means of end-to-side attachment. in the control group,nerve TLN was performed as In the EGF group. Injection of EGF/normal saline (20?g/10?l) and normal saline (10?l) was done at the distal site of peroneal nerve transected in the EGF group and control group for two weeks respectively. Histological,morphological and electrophysiological examinations were performed in 4 and 8 weeks after the operation. Results The cross area of the regenerated myelinated nerve fibres,axon numbers,motor nerve conduction velocity were significantly better in the EGF group than in the control group ( P

Objective To analyze suicide scene, damage morphology and case investigation of mountain type scenic spot for giving the references to determine the nature of cliff suicide cases. Methods The suicide cases collected from 2002 to 2012 in scenic spot of Mount Huangshan. The age, gender, native place, case location, damage inspection and behavior were analyzed. Results In the 52 suicide cases, the suicide rate of male was higher than that of female. The numbers from other provinces were higher than that of local province. The age was mainly range from 19 to 50. The time of suicide cases mostly happened between 16:00 to 24:00. The major damage was compound injury with varying degrees of traumatic brain injury, organic injury of pleuroperitoneal cavity and surface bruise and scratch. Conclu-sion In order to determine the nature of cliff suicide cases, it needs to work synthetically in the investi-gation of crime scene and interview.

Objective To study the feature extraction methods for the event related potential (ERP) evoked by mental arithmetical tasks through the sample entropy, in order to enhance the features of electroencephalograph (EEG) signals for brain computer interface (BCI).Methods Three types of mental arithmetic tasks including a simple counting, a random number and a stroke of Chinese character counting were proposed and 16 channel EEG signals were recorded from eight healthy subjects.The sample entropy method was then applied in characteristic signal complexity analysis.The characteristic and difference of signal complexity of ERP evoked by three types of mental arithmetical tasks were explored.Results The entropy value for EEG signal evoked by non-target stimulus was higher than that by the target stimulus with the significant difference (P＜0.01).The entropy of the mental arithmetic based on the Chinese characters counting task was significandy higher than that of the other two tasks (P＜0.05).EEG signals evoked by target/non-target were fundamentally signals under the state of attention or non-attention.Conclusions For the Chinese characters counting task, more complex information have been processed by the brain and the non-linear connection between nerve cells are much more complicated and a higher entropy value is achieved.In summary, the mental arithmetic task can effectively activate the relevant brain regions and the sample entropy can distinguish signals evoked by target or non-target stimuli.

Objective To find out the microalgae species in the spring water and the pollution route in the production process of drinking spring water. Methods 42 samples were collected from the workshop, the spring source, the product line and the repeated barrels in a water plant. The microalgae were examined by microscope, CCD imaging system and scanning electron microscope. Results 18 microalgae species were detected from the 42 samples including 4 species in Cyanophyta, 9 in Chlorophyta, 4 in Bacillariophyta and 1 in Euglenophyta. The dominant species occurred in samples of the floor around the workshop and the floor beside the wellspring bump were Achnanthes biasolettiana and Cymbella affinis, in the spring source were Chlamydomonas sp. and Ulothrix tenerrima, in the spring water barrel was Scenedesmus obliquus. Chlorella vulgaris was detected in all processes before the super-filter,and after filtered, no microalgae was detected, but in the product water, Chlorella vulgaris was still detected after enriched culture. Conclusion Usually, the microalgae polluted drinking spring water products is mainly Chlorella vulgaris and the pollution route is reusing of barrels.
