1.Stathmin: a potential tumor biomarker
Tumor 2010;(1):73-76
Stathmin, a ubiquitously expressed cytosolic protein(Mr=19×10~3), is also called oncogene protein 18 (Op18). Stathmin is involved in the assembly of microtubule (MT) and spindle by binding the tubulin protein. It plays a key role in cell proliferation, differentiation, regeneration, and migration and has regulatory effects on the signal transduction. Recently, it is reported that stathmin is overexpressed in a variety of human malignancies. It induces tumor cell migration and invasion by regulating MT depolymeri-zation. Its post-translational modification influences the interaction with p53 protein and is involved in the initiation and progression of malignant tumor. Stathmin alone or in combination with chemotherapeutics has been used for tumor therapy. The internal association of stathmin with cancer etiology is still unknown. So, further studies are needed to determine the role of stathmin as potential tumor biomarker and a drug target in tumor therapy.

4.Research advancement on measuring scale and influential factor of quality of life in patients with nasopharyngeal carcinoma
Journal of International Oncology 2006;0(11):-
The quality of life(QOL) in patients with nasopharyngeal carcinoma ( NPC ) has attracted people' s attention increasingly. Most of the studies focus on measuring scale and influential factor. Both the disease itself and many non-somatic factors can affect the patients' quality of life. In this review, we summarize these research advancements on measuring scales and influential factors, considering that it need more studies regard to quality of life in NPC patients, and it is very urgent and important to work out the special measuring scale of NPCQOL that suits Chinese culture and value system.

Objective: To compare the cognition of cancer patients and their relatives,so as to provide references for cognitive intervention.Methods: Cognition questionnaire consists 19 questions to which most patients and their relatives concern.Sixty new cases of cancer patients and their relatives were included in this study.Results: Answers to the 5 following questions from the patients and their relatives were different with statistical significance: do you know the diagnosis(83% patients know,97% relatives know,?2=5.93,P=0.015);whether to inform patients of diagnosis or not(87% patients chose yes,65% relatives chose yes,?2=7.69,P=0.006);is it necessary to tell patient intimate therapeutic regimen(77% patients thought it is necessary,62% relatives thought it is necessary,?2=8.71,P=0.013);who decide the method(s) of treatment(7% patients and 17% relatives' answer is the patients,?2=7.19,P=0.028);if the treatment is unable to cure your disease,what would be your option(80% patients and 97% relatives chose treatment,?2=8.09,P=0.004).Different educational background(?2=5.63,P=0.018) and occupation(?2=4.10,P=0.043) affected their cognition on being informed of the intimate therapeutic regimen.Conclusion:Patients` and relatives` cognition of being informed of the diagnosis and therapy are diverse from each other.In communication with them,doctors must treat them respectively.

OBJECTIVE:To improve the safety and effectiveness of total parenteral nutrition(TPN),and to provide reference for clinical rational use. METHODS:1400 TPN prescriptions in PIVAS from Jan. to Jun. 2013 were analyzed statistically in re-spects of rationality and stability. RESULTS:Among 1400 TPN prescriptions,there were 433 prescriptions of unreasonable glu-cose-lipid ratio(30.93%),782 prescriptions of unreasonable hot-nitrogen ratio(55.86%),443 prescriptions of unreasonable liquid amount(31.64%),1 261 prescriptions of unreasonable total calorie(90.07%)and 383 prescriptions of unreasonable treatment du-ration (27.36%). CONCLUSIONS:TPN prescription design is reasonable,but there are still some problems as low calorie,too high or too low hot nitrogen ratio,improper electrolyte dosage,improper duration of nutrition support. Clinicians should accurately assess the nutritional status of patients to design the prescriptions rationally and improve clinical safety and effectiveness of TPN. Pharmacists should further ensure the reasonableness of the prescription by prescription checking.

BACKGROUND:Traditional studies on foot and ankle biomechanics have limitation. Ankle joint was complicated and had big range of motion, so it is difficult to establish finite element models and to analyze the type of fracture.
OBJECTIVE: To construct the finite element models of distal tibial fractures and analyze the stability.
METHODS: CT data of ankle were colected from a normal male volunteer and the three-dimensional reconstruction of volunteer was made by Mimics software, and the effectiveness was verified. The ratio of different joint involvement and height of fracture block were assumed with Solidwork software, and finite element models of distal tibial fractures were established. Fracture stability was analyzed by ANSYS software using finite element method.
RESULTS AND CONCLUSION:The distal tibia fracture model was consistent with the relevant literature data, and finite element analysis could be further conducted. The ratio of articular surface involved was positively associated with fragment height and fracture displacement, and negatively associated with fracture stability. These results indicate that the three-dimensional finite element models of distal tibial fractures were successfuly established. Fracture stability was associated with the ratio of articular surface involved and fragment height.
10.Screw fixation of minimally invasive percutaneous and paraspinal muscle space approach for the treatment of thoracolumbar fractures
Journal of Regional Anatomy and Operative Surgery 2017;26(8):612-616
Objective To compare the clinical efficacy of minimally invasive percutaneous pedicle screw fixation and posterior paraspinal muscle space approach pedicle screw fixation for the treatment of thoracolumbar fractures.Methods Retrospectively analyzed the clinical data of 29 patients treated via minimally invasive percutaneous pedicle screw fixation(minimally invasive group) and 28 patients treated via posterior paraspinal muscle space approach pedicle screw fixation(paraspinal muscle approach group) from March 2013 to October 2015.The anterior vertebral height ratio,sagittal Cobb angle,surgical incision,operation time,number of fluoroscopy,intraoperative blood loss and ODI and VAS scores were compared between the two groups.Results All patients were followed up for an average period of 12.6 months (ranged from 6 to 18 months).At the end of 3 days,3 months and 12 months after operation,vertebral sagittal index and Cobb angle of the two groups were significantly recovered compared with the preoperative data(P<0.05),and the ODI and VAS scores were significantly lower than those before the operation,but the above indicators had no significant difference between the two groups(P>0.05).The surgical trauma and intraoperative blood loss of patients in the minimally invasive group were significantly lower than those of the paraspinal muscle approach group,while the operation time and fluoroscopy times were significantly higher than those of the paraspinal muscle approach group,and the differences were statistically significant(P<0.05).Conclusion Minimally invasive percutaneous and paraspinal muscle approach pedicle screw fixation are both effective,safe and reliable.Paraspinal muscle approach pedicle screw fixation has shorter operation time and easier operation,while minimally invasive percutaneous pedicle screw fixation has less trauma,less bleeding and faster postoperative recovery.
