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.

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.

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.

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 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

Objective To investigate the surgery outcomes between patients with different recovery states measured by visual analog scores (VAS),explore the relationships among surgery outcomes,bone cement,and degrees of pain relief,and to find out the best combination of cement volume and cement distribution for Percutaneous kyphoplasty (PKP).Methods There were 220 patients with 220 vertebra,from January 2012 to January 2014,who received PKP in our hospital.Patients were divided into two groups,on the basis of different VAS.The epidemiological data,operative effect,and surgical complications were compared between two groups.Characteristic curve (ROC) was used to analyze the effect of bone cement dosage and distribution on the diagnosis of patients with different recovery state.The correlation was analyzed between the dose and distribution of bone cement and surgery outcomes.Moreover,logistic regression analysis was used to assess the safety of cement implantation.Results A total of 77 recuperators and 143 non-recuperators were included in the study.Two groups of patients in epidemiological data showed no significant difference.The surgery duration,bone cement injection dose,cement distribution,vertebral height restoration rate and improvement of kyphotic angle in the recuperator group were all significantly higher than those in the non-recuperator group.Whether small dose and large dose of bone cement volume and expanded the bone cement distribution area could significantly improve the patient of operation after the recovery rate and bone cement dose with extensive bone cement distribution area and large bone cement dose with limited bone cement distribution area had the same operation after the recovery effect (x2 =2.880,P =0.090).When the cement volume was constant,cement distribution was positively correlated with the restoration rate of vertebral height and improvement of the kyphotic angle (r2 =0.207,P ＜ 0.01;r2 =0.159,P =0.02).Conclusions The value of cement distribution is better than cement volume in relieving patient pain for diagnostic.For PKP,cement distribution above 0.49 with small cement should be suggested.

Objective To improve the clinical use of donor kidneys having abnormal blood vessels.Methods The kidneys with abnormal blood vessels were transplanted after vessel reconstruction was made. Various techniques were used for different types of abnormal arteries and veins.Results Of 78 donor kidneys with abnormal arteries (23 kidneys also have abnormal veins) been transplanted, 77 grafts excreted urine immediately and the recipients' blood creatinine level were normal was weeks after transplantation. During a period of one-year follow-up, no vascular complication was observed. One kidney was resected because of uncontrolled bleeding secondary to poor venous return. Conclusion Donor kidneys with vascular abnormalities can function well after proper reconstruction.

0.1). Conclusion This method is simple, rapid and accurate for determining formaldehyde in indoor air.
