ABSTRACT
The traditional-immunological strategies for clinical laboratories often rely on large and expensive instruments and skilled operators, and the measurement time is also long. However, the sensitivity of these strategies is still unsatisfactory. It is urgent to research and develop the point-of-care testing (POCT) featured as a highly sensitive, accurate, and rapid/POCT diagnosis. The Microfluidic chips have multi-advantages that are suitable for the clinical POCT diagnosis: high sensitivity, throughput, and automation. Recently, the Microfluidic-immune chips developed based on the microfluidic technology combined with immune detection have considered not only hotspots in the related research but also benefit to the tumor marker detection, antigen and antibody detection of infectious diseases, autoantibody detection, hormone detection, and other fields. However, there are still many challenges to be overcome during the application of chips, such as more effective microfluidic manipulation, more sensitive collection, and analysis of reaction signals.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
