15 paired tendons of the flexor digitorum sublimis and profundus, 5 pairs of tendons of both the flexor pollicis longus and the flexor hallucis longus were studied.The results were outlined as follows:(1) The morphological modification of the segment of the tendon of the flexor digitorum profundus in the tunnel formed by the splitting of the sublimis tendon fit well the varying shape of the tunnel.(2) The arrangement of the fiber bundles in the tendon of the flexor digitorum profundus appears to be in a spiral twist.(3) The fiber bundles of the tendons of the flexor pollicis (hallucis) longus are arranged similarly to those of the flexor digitorum profundus. It is further suggested that both muscles are homologous in evolution. (4) Morphological changes of the tendon are due to the change of the direction of its fiber bundles inside.(5) It is suggested that the twists and the intertextures of the fiber bundles of the tendon may increase the strength of the tendon and may be related to the transmission of the muscle contraction.(6) On each side of the tendon of the flexor pollicis longus and flexor hallucis longus, a definite lateral fascicle was found.

The muscle arrangements of esophago-gastric junction were observed in 30 human specimens. Muscles of the esophago-gastric junction consist of two layers-an outer longitudinal oblique layer and an inner circular oblique layer. At the top of esophageal vestibule 2 superficial muscle bundles may be identified. They are continuous with longitudinal muscle fibers of the tubular esophagus and runs to the stomach. The deep circular layer of the tubulovestibular junction is thicker than that of the tubular esophagus. It looks like a sphincter which lies 27.06 2.11mm above the cardiac incisure. At the middle segment of the esophageal vestibule some of the circular muscle fibers turn into spiral or loop forms. At the terminal portion of the vestibule two semicircular muscles separately localized towards the fundus and the lesser curvature of the stomach. They overlap at the back or at the front of the stomach. A small bundle opposite the gastric sling fiber demarcates the right margin of the esophago-gastric junction.

The amount of ~3H-TdR incorporation into D?A of FRTL5 cells was expressed as CPM/?gD?A. THe responsibity of FRTL5 cells to stimulators such as TSH was expressed as % against thJ control CPM/?gDNA of the experimental group divided by that of the control. The responsibilities of FRTL5 cells which were recovered after being fr-o zen under-180℃ for a long time, to TSH 200?g/ml were 2741% and 3028% respectively, and the responsibilities of cells cultured in TSH media continuously for a long time, to TSH 200?u/ml and 2000?u/ml were 736% and 719% respectively. There was statistically significant differences between the two groups of the cells mentioned above. This showed that freezing FRTL5 Cells for a long time Such as 2 months was able to recover the decreased responsibility of the Cells due to a long continuous TSH culture.

The diaphragm of 36 specimens (34 fetuses and 2 adults) of both sexes were studied anatomically. The central tendon of the diaphragm are trilaminar. The aponeurotic fiber bundles of the diaphragm are always split into two in a V-shape. Most of the aponeurotic fibers of the anterior leaf of the central tendon continue across the midline with the corresponding aponeurotic fibers of the opposite side to form the superficial and deep layers of the lateral leaf. The diaphragm with its central tendon has a structure similar to the digastric muscles (between the anterior and posterior, the left and right). The central tendon may be considered as a common area of decussation of intermediateaponeurosis rather than an insertion of the peripheral fleshy fibers.The present study shows that the splitting of the aponeurotic bundles of the central tendon and trilaminar arrangement of each lobe of the central tendon are formed early in the fetal period. It is suggested that the arrangement of the aponeuroses of the central tendon may give the diaphragm more elasticity and tenacity, which is advantageous for respiration.

Forty human fetuses ranging from C-R length 72 mm (which corresponds to a developmental stage of the second week in the third month of the embryo) to fullterm were used to investigate the nutrient arteries of the femora using the dissection method and roentgenography. In comparison with adults, there are apparently more (P

This paper reports a study of three components of stature for a sample of 605 healthy children aged 8-15. Suprapelvic height, pelvic height, and subischeal height are obtained by calculation on the basis of standing height, sitting height, total lower limb length, ankle height and bi-iliac width. By statistical analysis, sexual dimorphism is revealed in both suprapelvic height and pelvic height. The increase in pelvic height is greater in girls than boys, and occurs before the appearance of secondary sexual charateristics. The relationships between suprapelvic height and idiopathic scoliosis, and between pelvic height and low back pain are discussed.

Objective To analyze the CT and MRI features of giant cell tumors of the skull. Methods 8 cases of giant cell tumors of the skull proven surgically and pathologically were analyzed retrospectively. CT and MRI(6 cases with post contrast CT and 5 cases with post contrast MRI scans)were performed in all cases. All tumors were excised surgically. Two weeks later,all patients undertook postoperative radiotherapy with the dosage of 4 500-6 000 cGy for five to six weeks. Results CT scan showed bone destruction and calcification. Most of the tumours were well defined with low signal intensities on T1 WI images, T2 WI images showed ununiformity signal. The low signal on T1 WI was still low signal intensity on T2 WI which suggested calcification. All patients had no distinctive change within the follow up period. Conclusion CT is able to clearly show bone destruction and calcification. MRI is superior to CT in demonstrating the outlines of the tumours. CT and MRI are effective methods in the diagnosis of the giant cell tumors. Surgery and postoperative radiotherapy are effective methods in the treatment of the giant cell tumors.

Quantitative analysis and developmental observations on the planum temporale of 157 fetus and infantal brains have been made. The results are as follows: 1) left planum temporale of 82％ of the fetal brains and 76％ of the infantal brains are larger than the right. 2) Average area values of the left planum temporale are signifcantly larger than the right. 3) The earliest appearance of the planum temporale is in the sixth gestational month. 4) Rate of appearance of the left planum tempo-rale in fetuses is higher than that of the right. 5) Right/left ratio of planum temporale increases with the development of the embryo. These findings indicate that the asymmetry of the left and right planum temporale is present since the appearance of the planum temporale, and changes as the fetus develops.

Objective To explore the technique and the clinical value of Neuroform stents in combination with Guglielmi detachable coil(GDC) to treat wide-necked basilar artery aneurysms.Methods 30 cases with wide-necked basilar artery aneurysms were treated with Neuroform stent combined with GDC.Of 30 wide-necked basilar artery aneurysms,the location of lesions was at basilar tip in 16,basilar trunk in 9 and the beginning of the basilar in 5.Results In 30 cases,total occlusion was achieved in 25 and partial occlusion in 5 patients.The thrombosis within stent occurred in 2 patinets,and remainder of patients recovered well.There were no thromboembolic events in 20 cases followed up for 3~6 months.Twenty-two patients were angiographically followed up for 3 months after the procedure,among them,the aneurysms visualized and the arteriae burdened aneurysms were passed free in densely packed and 3 aneurysms with neck remnant.Conclusion The Neuroform stent is a easy and safe intracranial stent for embo1ization of wide-necked intracranial aneurysms,especially suitable for wide-necked basilar artery aneurysms with severely tortuous intracranial artery.

In order to explore the expression of PI-3K in T lymphocytes of asthmatic rats and the relationship between PI-3K and activation of T lymphocytes, 24 Wistar rats were randomly divided into 4 groups: normal control group, asthmatic one-week group, asthmatic two-week group and asthmatic four-week group. T cells were purified from blood of each rat and the expression of PI-3K was observed by immunocytochemical fluorescence staining, the semiquantitative fluorescence intensity was measured by HPIAS-2000 analytic software, and the expression of IL-4 in supernatants was detected by ELISA. The results showed that the fluorescence intensity of T lymphocytes in asthmatic groups was significantly higher than that in normal control (P<0.001), indicating that the expression of PI-3K in T lymphocytes of asthmatic rats was significantly higher than that in those of normal controls, and the difference between acute and chronic stage asthmatic groups was significant (P<0.05). The expression levels of IL-4 protein in supernatants of asthmatic T lymphocytes were significantly higher than those in the normal controls (P<0.05). There was a significant positive correlation between the expression of PI-3K in T lymphocytes and the IL-4 protein expression in supernatants (r=0.583, P<0.01). It was suggested that PI-3K signal pathway may participate in the processes of activation and other cytological effects of asthmatic T lymphocytes, thus may play an important roles in the pathogenesis of asthma.
