[Objective]To evaluate curative effects of Osteoset~ synthetic bone transplants and internel fixations on calcaneus fracture.[Method]Twenty-three patients with calcaneus fracture,who were treated by Osteoset~ synthetic bone transplants and internel fixation,were followed up by plain X-Rays and JOA functional questionnaires.Fracture patterns were based on Sanders methods.[Result]A series of 23 patients,7 of which were sanders Ⅱ,15 were sanders Ⅲ,3 were sanders Ⅳ,were treated with ORIF and Osteoset~ implants.The preoperative Blher's angle was 4.8 degrees(standard deviation 6.6 degrees).Blher's angle increased to a mean of 26.8 degrees(SD 8.6 degrees) postoperatively.In the first 3 months after surgery,a mean decrease in the Blher's angle of 0.4 degrees(SD 2.27 degrees) occurred.One month after surgery osteoset synthetic bone transplants,which was replaced by new bone,were gradually absorbed and degraded.JOA questionnaires suggested that the whole effective rate was 92 percent.[Conclusion]Osteoset synthetic bone transplants and internel fixations has good therapeutic effects on patients with comminuted calcaneus fracture.Osteoset~ synthetic bone has the same effects as autogenous bone.

The postnatal development of the efferent projections to the lumbosacral spinal cord from the brain stem of rats were studied with HRP retrograde transport method. Fifty per cent solution of HRP was slowly injected into the intumescentia lumbalis on its right side in 18 albino rats from postnatal 1-35 days. The HRP labelled cells were found in the following nuclei:1. Of the midbrain: the nucleus ruber, substantia nigra and nucleus raphe dorsalis.2. Of the pons: the nucleus reticularis pontis oralis, nucleus reticularis pontis caudalis, locus coeruleus, nucleus subcoeruleus, nucleus raphe magnus, nucleus vestibularis lateralis, and nucleus vestibularis medialis.3. Of the medulla oblongata: the nucleus raphe obscurus, nucleus raphe pallidus, nucleus reticularis ventralis, nucleus reticularis gigantocellularis, nucleus reticularis lateralis, nucleus tractus spinalis nervi trigemini, nucleus commissuralis (Cajal), nucleus prepositus hypoglossi, and nucleus gracilis.The number of the labelled cells in the above nuclei increased steadily with age. The results of present study showed that there was a postnatal developmental process in the efferent projections from the brain stem to the lumbosacral cord. The maturity of the projections from ruber nucleus and locus coeruleus were later than those of the vestibulospinal and reticulospinal tracts. The postnatal developmental process of the brain stem projections to the lumbosacral spinal cord were completed by one month after birth.

An intercostal nerve-spinal cord implantation and semitransection of the spinalcord at the point between the origin and insertion of the intercostal nerve was madeon ten adult dogs and two monkeys.One to two weeks after this operation,paraly-tic legs following semitransection of the spinal cord recoverded from the paralysis.The implanted nerves were cut during the different period from 124 to 366 days.The function of the legs of four animals which had recovered paralysed again aftersurgical section of implanted nerve.Histologically,the inserted nerves in the spinalcord were recognized in these animals.Many of the growing fibers extended fromdistal end of the inserted intercostal nerve into the gray and white matter ofthe distal segment of the spinal cord.It is considered that the efficacy of the inter-costal nerve-spinal cord implantation depends upon the choice of the symptomaticindications and the success of the implantation procedure.

AIM: To explore a new compute tomography (CT) for the localization of intraocular foreign bodies (IOFBs).METHODS: After CT ocular horizontal and ocular axial scan,the foreign bodies on the eyeball wall or retinal surface in 26eyes were localized by means of the combination of CT ocular axial scan and meridian plane reconstruction (new method),ocular horizontal scan and ocular axial scan (conventional method Ⅰ) as well as ocular horizontal scan right angle coordination (conventional method Ⅱ) separately. According to the criteria of indirect ophthalmoscope localization and direct observation during operation, the relative accuracies of corresponding points of the foreign bodies on sclera surface along meridian and latitude were measured.RESULTS: In the 26 cases, the mean relative accuracies of corresponding points of foreign bodies on sclera surface along meridian and latitude were 1.53mm、1.64mm (new method), 1.37mm、1.64mm (conventional method Ⅰ) and 2.02mm、2.55mm (conventional method Ⅱ) respectively.There was no statistical difference between the new method and the conventional method Ⅰ, whereas there was statistical difference between the new methods and the conventional method Ⅱ (along meridian: P＜0.05; along latitude:P＜0.01).CONCLUSION: Compared with the conventional methods,the new method is simpler, more visible and more potential in the clinic.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

Objective To investigate the relationship between platelet maximum aggregation rate(MAR),platelet thrombocyt-ocrit(PCT),platelet count(PLT),platelet distribution width(PDW)and mean platelet volume(MPV)with the course of acute cere-bral infarction(ACI)to provide the basis for its clinical early diagnosis and treatment.Methods 107 patients with ACI in our hospi-tal were selected and divided into the great infarction group(infarction size >10 cm3 ),middle infarction group(infarction size 4-10 cm3 )and small infarction group(infarction size<4 cm3 )according to the infarction lesion size by head CT or MRI and the infarction volume calculated by the Pullicino formula(length×width×layer number/2),40 healthy individuals were selected as the healthy control group.MAR,PLT,PDW,MPV and PCT were detected before and after the induction by PLR-06.Results (1 )Compared with the control group,PLT,PCT,PDW and MPV before the induction by PLR-06 in the great infarction group were obviously in-creased(P <0.01);PLT,PCT,PDW and MPV in the middle and small infarction groups were increased(P <0.05).(2)Compared with the control group,MAR after the induction by PLR-06 in each infarction group was increased(P <0.05);PLT had no statisti-cal difference among the groups(P >0.05 );PCT,PDW and MPV in the great and middle infarction groups were increased(P <0.05);PCT,PDW and MPV in the small infarction group had no statistical differences(P >0.05).Conclusion The change of the platelet aggregation rate,number and volume is closely related with the occurrence and development of ACI,monitoring their change has important clinical significance to prevention and treat ACI.

Objective To analyze the abnormal detectable rates of different kinds of blood test indexes before and after treatment in the patients with snake bite and to probe into the change condition of these indexes after different snake bite .Methods The inpa‐tients with clearly diagnosed what kind of snake bite in the past two years were selected as the research subjects .The multiple blood test indexes were determined before and after treatment in these patients .The abnormal detectable rates of these indexes were ana‐lyzed and compared among various snake bite patients .Results The different kinds of snake bite all could cause the different de‐grees of changes in some detection indexes among partial patients .Specially ,the detectable rates of WBC ,PT ,APTT ,TT ,D‐D ,CK , CK‐MB ,LDH ,Urea ,Cr and Cys‐C increase and PLT and Fbg decrease caused by viper bite were apparently higher than those caused by other kinds of snake bites (P<0 .05) .The detectable rates of CO2 increase and K+ decrease in the coral snake bite were apparently higher than those in trimeresurus gramineus ,cobra and viper bite (P<0 .05) .Conclusion Because the snake species and toxicities are different in the various snake bites ,so the caused changes and the abnormal detectable rates of blood test indexes also are different .
