1.THE BLOOD SUPPLY OF THE RAMUS SUPERFICIALIS OF THE RADIAL NERVE, AND NERVUS CUTANEOUS ANTEBRACHII LATERALIS
Acta Anatomica Sinica 1954;0(02):-
1. Fifty upper limbs of adult cadavers were dissected under an operating microscope.2. The ramus superficialis of the radial nerve is about 180 mm long, and springs from the radial nerve at a level about 16 mm below the medial epicondyle of the humerus. As the radial artery, it can be divided into superficial and deep parts by the overlapping of musculus brachioradialis. The junction between the two parts corresponds to a plane which divides the forearm into upper 2/3 and lower 1/3. The width of the ramus superficialis increases gradually as it runs downwards, and its cross section looks elliptical distally and somewhat circular proximally. Each of the two parts of the ramus superficialis receives 1~4 arteries from the lateral cutaneous arteries or muscular branches of the radial artery. Measurements were made to determine the position of the origin of these arteries.3. The nervus cutaneous antebrachii lateralis divides into two branches in the forearm, and receives 2~8 arteries mainly from the lateral cutaneous branches of the radial artery. It usually gives a branch communicating with the ramus superficialis of the radial nerve. The nervus cutaneous antebrachii lateralis can be found easily at the point just 5~6 mm lateral to the junction of the superficial and deep parts of the radial artery.4. The applied anatomy of the vascular pedicle nerve graft was discussed.

Objective To observe the characteristics of vertical cast-off bloodstain pattern by different hitting-tools. Methods The regular hitting tools, a kitchen knife, a dirk, a plane set-hammer and an iron pipe, were selected. At a distance of 30 cmaway fromthe wall, the hitting tool with 5 mL fresh chick-en blood made the cast-off bloodstain fromtop to bottom. Then the holistic distribution characteristics ( length , width and density ) of cast-off bloodstain and morphology characteristics ( length , width and contact angle) of first single cast-off bloodstain were analyzed. Results The distribution length of cast-off bloodstain formed by dirk was minimum( P<0 .05 ) . The distribution width of cast-off bloodstain formed by kitchen knife was minimum(P<0.05). Except the pair of kitchen knife and plane set-hammer, the distribution density between each two tools had statistical differences (P<0.05). The length of first single cast-off bloodstain formed by plane set-hammer was longest compared (P<0.05). The width of first single cast-off bloodstain had statistical differences between kitchen knife and plane set-hammer, and between dirk and plane set-hammer (P<0.05). Conclusion The type of hitting tool could be inferred by the specific characteristics of cast-off bloodstain pattern formed by every specific type of hitting tool in crime scene.

Objective To survey on the graduate students about their own requirements, the guid-ance of tutors and the compliance, and put the gists for the educators and administrators. Methods Using the comprehensive questionnaires including Eugenie Creativity Test and Motivation Scale, the investigation surveyed on 900 graduate students in a medical university about their requirements and tutors' concerned aspects in their opinions, which was whether influenced by Intelligence (creativity), the Non-Intelligence factors (motivation) or not. Epidata 3.1 was used to input data of the investigation, and SPSS 16.0 statistical software was used to analyze it. The items were set as multiple-choices, and the percent of responses was used. Results The students thought the tutors' concerned aspects were mainly creative thinking [61.1%(1129/1847)], research methods [58.2%(1075/1847), specialty knowledge [41.8%(772/1847)], scientific spirit
[35.4%(654/1847)], academic morality [24.3%(516/2124)] and book knowledge [5.4%(100/1847) ], while the graduate students paid more attention to its research methods [72.4%(1538/2124)], innovative thinking [64.0%(1359/2124), professional knowledge [60.0%(1274/2124)], the spirit of science [33.9%(720/2124)], academic morality [24.3%(516/2124)] and book knowledge [10.0%(212/2124)]. The percentages of research methods and specialty knowledge concerned by most of the students were higher than those tutors' con-cerned in the students' opinion. The percentages of specialty knowledge concerned by the students with high innovation and motivation were 56.2%(443/789) and 58%(345/595), which were higher than those concerned by the tutors 38.5%(255/662) and 29.4%(148/503). Conclusion In the students' opinion, tutors concerned more creative thinking, the students concerned more research methods, while they concerned similarly in the other aspects. For the students, the guidance of the tutors cannot still meet their study demands, espe-cially in research methods and specialty knowledge. Those with different motivations and innovations have different study requirements.
