BACKGROUND:Studies have shown that the physical development potential is often associates with certain combinations of hand print features.
OBJECTIVE:To analyze the body shape and structure characteristics of national women’s handbal team athletes.
METHODS:Fifty national women’s handbal team athletes were col ected from Shanghai, Beijing, Tianjin and Anhui provinces and PLA. The body shapes of the athletes were measured by the Research Institute of National Sports Council, and the hand prints were col ected. The common factors of body shape and structure characteristics were analyzed with factor analysis method, including height, weight, forearm length, wrist circumference, hand length, hand width and index finger length and large-handedness index.
RESULTS AND CONCLUSION:The body shape and structure characteristics of national women’s handbal team athletes could be divided into four types:long trunk lean type indicator, hand skeleton and muscle fiber development level index, flexible quality indicators as wel as the alertness and mental level indicators. The long trunk lean type indicator was the main factor to affect body shape and structure characteristics of national women’s handbal team athletes.

A L-arginine-producing mutant UN100-12(SG~(r),AE~(r)) was derived from Corynebacterium glutamicum ATCC138761 by combination treatment with ultraviolet(UV) and N-methyl-N-nitro-N-nitrosoguanidine(NTG). It could accumulate 16.6g/L L-arginine in the medium containing glucose as carbon source and ammonium sulfate as nitrogen source, when it was culrured at 30℃ for 4 days. And also this mutant has good stability of descendiblity of L-arginine.

BACKGROUND: The development of hip joint in children with developmental dislocation of the hip (DDH) has been evaluated by X-ray plain film, which mainly presents Shen Tong's line continuity and epiphyseal nucleus position. There is still a lack of quantitative and objective evaluation methods. OBJECTIVE: To evaluate the rotation center and dislocation degree in DDH children by using three-dimensional (3D) computed tomography (CT).METHODS: Preoperative 3D CT was performed for 16 unilateral DDH from December 2010 to December 2014 in Tongji Hospital of Huazhong University of Science and Technology, with 4 males and 12 females, at the mean age of (4.42±2.59) years. There were 10 cases on the left side and 6 cases on the right side. 3D digital models were constructed by analysis. The 3D coordinate system was established with reverse engineering software. In 3D coordinatesystem, using inverse solution method of sphere fitting engineering, the rotation center of the acetabulum, the rotationalcenter of the femoral head, and the radius of ossification were constructed. Ossific radius ratio and dislocation lengthwere calculated. RESULTS AND CONCLUSION: (1) The acetabulum has the same point as the rotation center with the head of femur,and no significant difference in X, Y, and Z coordinates was detected (Px > 0.05, Py > 0.05, Pz > 0.05). However, it is notthe same condition in ipsilateral acetabular rotation center and femoral head rotation center, showing significant differences (Px=0.052, Py < 0.05, Pz < 0.05). (2) There were no significant differences in ossific radius between the healthy and affected sides (P > 0.05). The ossific radius was (21.37±4.42) mm and (20.14±3.14) mm on the healthy and affected sides of the femoral head (P < 0.05). (3) There was no significant difference in ossific radius ratio between healthy and affected sides (0.544±0.069 and 0.522±0.088; P > 0.05). (4) The dislocation length was 8.64-35.28 mm, mean (19.47±7.84) mm. (5) These findings suggest that 3D CT reconstruction can construct 3D digital models of DDHchildren. Thus, the accurate rotation center of the hip can be identified so as to precisely measure the dislocation length.

Objective: To investigate the neuroendocrine properties of adrenalcortical tumors. Methods: We retrospectively reviewed the clinical data of 99 adrenalcortical tumor patients, who were treated in Changzheng Hospital form June 1999 to June 2005. Expression of neuron specific enolase (NSE), chromogranin A (CgA) and synaptophysin (Syn) proteins were examined by immunohistochemistry (S-P method) using monoclonal antibodies. The general data of patients, including the age, symptoms, laboratory findings, and pathological types, were collected and subjected to statistical analysis with SAS v6. 12 software. Results: The expression of all the above 3 proteins was found in adrenalcortical adenoma tissues, with the positive rate of NSE being 80%, the positive rate of CgA being 48.9%, and the positive rate of Syn being 75.6%; the positive rates in the adrenalcortical carcinoma tissues were 77.8%, 22.2%, and 77.8%, respectively; and those in the normal adrenal tissues was 20%, 0%, and 10%, respectively. The positive rates of 3 proteins in adrenalcortical tumors was significantly higher than those in the normal adrenal tissues (P

As one of the most serious hereditary neuromuscular disease, spinal muscular atrophy (SMA) is caused by the loss or mutation of survival motor neuron 1 (SMN1) gene. It leads to a decrease in the level of SMN protein and a consequent loss of alpha neurons and progressive muscle atrophy resulting in the progressive muscle weakness, the significant disability and the shortened lifespan. Up till now, only three drugs have been approved for SMA, including the gene therapy drug onasemnogene abeparvovec. The antisense oligonucleotide drug nusinersen and and the small molecule chemical drug risdiplam were briefly introduced. Some representative samples of the small molecule chemical drugs and antisense oligonucleotide drugs targeting SMN2 in the clinical trial or preclinical research phases were also reviewed.

Objective To study the effect of HAI and/or PVI after radical resection of hepatocellular carcinoma (HCC) for preventing recurrence.Methods From Jun. 1995 to Apr. 2000, 49 patients with HCC were undergone radical tumor resection. They were divided into 4 group: the treatment combined with HAI and PVI was given in group I(12 cases), HAV alone in group II (8 cases); PVI alone in group III (15 cases); nothing in group IV (14 cases). All patients were followed up for 6 months to 5 years. Results Recurrence rate at one year didn't show significantly lower in group I, II and III than that in grou IV. Survival rate in one year showed no significant difference in 4 groups. Recurrence rate in three years was significantly lower in group I and II than that in group IV. Survival rate in three years was significantly higher in group I and II than that in group IV. Recurrence rate and survival rate in five years showed no significante difference in four groups. Conclusions The treatment of radical resection of HCC combined with HAI and/or PVI is simple and safe. It is an useful method for preventing tumor recurrence.

[Objective]To review the therapeutic effect of TSRH in correction of coronal plane,sagittal plane and horizontal plane malformation of the idiopathic scoliosis,and to evaluate the result of screw-rod and screw-crook-rod system.[Method]A total of 79 idiopathic scoliosis patients who were corrected with TSRH were analyzed.There were 48 males and 31 females with an average age of 15.5 years.Only pedicle screws system was used in 56 cases,pedicle crook or vertebral plate crook in thoracic vertebra,pedicle screws system in lumbar vertebrae were used in 23 cases,then the results of two groups were compared.[Result]Cobb's angel in coronal plane was corrected from 18 to 31 after operation,the correction rate was from 56 percent to 87 percent,with an average of 68 percent;while Cobb's angel in sagittal plane was corrected from 21 to 33 after operation,with an average of 25.Rotation was corrected by I degree,heights were increased by 3 cm in average.The mean followed-up duration of 63 cases was two years and a half year.There was significant difference between the two groups in correction rate in coronal plane and sagittal plane,also in loss of correction in coronal plane.[Conclusion]TSRH could make satisfying results in correction of idiopathic scoliosis,and the result would be better if pedicle screws system is used.
