ObjectiveTo investigate and understand the cognitive level of occupational protection of staff in sterilization and supply center. Methods180 staff in sterilization and supply center were taken for a retrospective questionnaire investigation.The survey included:general information of the object,cognition about occupational protection,wearing of protective equipment,influence of occupational hazards,sharp instrument injury and the handling of injury cases. ResultsThe cognitive level of occupational protection in the sterilization and supply center was low.Some of the staff did not fully implement the wearing of protective equipment rules in the decontamination areas.In the occupational hazards,sharp instrument injuries accounted the highest incidence.The situation of taking blood tests after injury,injection of high titer globulin,report to the higher-ups and follow-up investigation were rare,and even some staff gave no handling of the wound. ConclusionsThe cognitive level of occupational protection in the sterilization and supply center is low.It not only needs professional training to improve cognitive level of occupational protection but also effective protective measures.The management department should establish a complete protection regulations of occupational safety and strict supervision in order to prevent the occurrence of occupational exposure,ensure staff safety,and at the same time,health records should be established in order to understand health status of staff.

FOXM1 (Forkhead box M1), one factor of the Forkhead family, has three subtypes (FOXM1a, FOXM1b, FOXM1c). The current study focuses on FOXM1b and FOXM1c. FOXM1 regulates transcription of prolifemtion-nssociated genes and plays a vital role in embryogenesis as well as reorgani-zation. Recent studies have shown that FOXM1 is closely related with tumor occurrence and development. Tumors with high expression of FOXM1 are often poorly differentiated, highly malignant, distantly metastat-ic, poorly predicted. FOXM1 has a influence on the tumor proliferation, invasion, metastasis and angiogene-sis through regulating its downstream tumor-related genes. At present, the synthesis and study of the anti-tumor chemicals targeting FOXM1 offer a possibility of the FOXM1 in clinical applications. More and more researchers attach importance to its tumor therapeutic value both at home and aboard. This paper will make a review about the lastest FOXM1 research in oncology.

BACKGROUND:How to preserve the fertility and ovarian function in patients with procreation needs has important significance and broad application prospects. OBJECTIVE:To summarize the recent studies about ovarian tissue cryopreservation, preservation and evaluation methods, and to explore the best solution for ovarian tissue freezing. METHODS:An online computer-based retrieval of PubMed database and Wanfang database between January 1994 and January 2014 was performed by the first author. The key words were ovarian tissue, ovarian tissue cryopreservation, freezing factors in English and Chinese. Final y 59 literatures on the ovarian tissue cryopreservation technique, influencing factor of cryopreservation, resuscitation, and human ovarian tissue transplantation were included. RESULTS AND CONCLUSION:Currently, laboratory methods of ovarian tissue cryopreservation are divided into slow-rate freezing, ultra-rapid cooling and vitrification technology. The freezing effect may vary in different patients, tissue sections, cryoprotectants species, penetration time and frozen carrier. After the recovery, the histological morphology of granulosa cells and fol icles was observed. The fol icles were counted to evaluate ovarian tissue. Freeze-thaw effects were evaluated by observing the changes of subcellular structures. The apoptotic signals were also detected. Immunohistochemical analysis was applied to detect the proliferation after recovery and apoptosis-related information. Variation in the in vitro culture reflected endocrine levels. Genetic level detection was also performed. In recent years, frozen ovarian tissue is clinical y applied for the transplantation, to restore reproductive endocrine function of the patients, or get mature germ cells, thereby preserving female fertility. However, there are stil some questions about cryopreservation of ovarian tissue, which need further study.

Objective To discuss the appropriate timing of providing enteral nutrition through nasojejunal tube for patients with severe craniocerebral injury.Methods 126 cases of patients were divided into 3 groups randomly,providing enteral nutrition through naso-jejunal tube for the first group,the second group and the third group within 12～24 hours,48 hours later and 72 hours later after injury respectively.The nutrition situation of 3 groups was recorded 6 hours later,48 hours later,on the 5th day and the 10th day,including indicators such as total serum protein,blood albumin,serum creatinine,etc and complication cases of diarrhea,hemorrhage of digestive tract,palirrhea,aspiration,inhalation pneumonia and so on within 2 weeks after injury.Results In terms of indicators of albumin,creatinine 48 hours after injury and total protein,albumin and creatinine on the 5th day and 10th day,the first group were better than the second and third group,there were statistic differences between the three groups.Complication comparison within 2 weeks after injury:the difference of palirrhea cases among the three groups was significant,the third group had a higher ratio than the first and second group.And there was no statistic difference in the other indicators like diarrhea,hemorrhage of digestive tract,aspiration and inhalation pneumonia.Conclusions It is high time that patients with simple severe craniocerebral injury are provided with enteral nutrition through naso-jejunal tube within 12 to 24 hours,which can improve patients nutrition situation without the increase of the complications.

Objective To investigate the clinical effects of laparoscopic sleeve gastrectomy with duodenaljejunal bypass (LSG + DJB) for the treatment of type 2 diabetes mellitus.Methods The clinical data of 17 patients with type 2 diabetes mellitus who underwent LSG + DJB at the Xijing Hospital of the Fourth Military Medical University from March 2013 to February 2014 were retrospectively analyzed.The fasting blood glucose,postprandial 2-hour blood glucose,glycosylated hemoglobin (HbA1c) and body mass index (BMI) in 17 patients before operation were (9.2 ± 0.6) mmol/L,(14.4 ± 2.2) mmol/L,8.3％ ± 1.2％ and (29.4 ± 2.2) kg/m2,respectively.All the patients received LSG + DJB and were followed up by outpatient examination up to March 2015.The pre-and post-operative 12-month fasting blood glucose,postprandial 2-hour blood glucose,HbA1 c and BMI in 17 patients were compared.Measurement data with normal distribution were presented as-x ± s and analyzed by the t test.Results All the 17 patients received successful laparoscopic LSG + DJB without conversion to open surgery.The operation time,volume of intraoperative blood loss and recovery time of postoperative gastrointestinal function were (141 ±53)minutes,40 mL and 2.5 days.Of 3 patients with postoperative complications,1 patient with anastomotic leakage at postoperative day 5 received reoperation by laparoscopic Roux-en-Y gastric bypass,1 patient with digestive tract obstruction at postoperative day 10 released obstruction by reoperation and 1 patient with left subphrenic abscess and leakage at the upper of the stomach at postoperative week 2 was cured by the symptomatic treatment.The duration of hospital stay was 5.2 days.All the patients were followed up for a median time of 16 months (range,13-24 months).The postoperative 12-month fasting blood glucose,postprandial 2-hour blood glucose,HbA1c and BMI in 17 patients were (5.5 ± 0.7)mmol/L,(8.8 ± 1.7)mmol/L,5.1％ ± 0.7％ and (24.7 ± 2.3)kg/m2,which were significantly different from preoperative indicators (t =19.96,10.52,12.06,31.99,P ＜ 0.05).During the follow-up,no anastomotic ulcer and stenosis,dumping syndrome and severe malnutrition were occurred.Conclusion LSG + DJB is safe and feasible for the treatment of type 2 diabetes mellitus,with a good short-term hypoglycemic effect.

According to the theory of microscopic system reform in higher education, a total of 927 college students of different majors from Beijing University of Chinese Medicine were investigated by using SIMPP method. It indicated that through promoting the study of self-prepared, learning state and learning effect, students can enhance their learning ability of the admission acceptance. From the perspective of teachers, the students' self-study ability can be fully mobilized using individual person-alized teaching method. Then, the initiative of university education in the teaching and learning can be improved. Ultimately, the efficiency of student learning can be improved.

Interest in learning can not only stimulate students' enthusiasm for learning, but also directly affect the quality of higher education. In this paper, the questionnaire of the related factors of college students' interest was designed to carry out micro-system engineering research. The factors as-sociated with college students' interest in learning and their complex relationships were investigated by using methods of systems science and systems engineering. The results shows that the students who can actively participate in after-school learning discussions , feel good in lectures and have clear learning objectives, are interested in learning. And at the same time, the teacher's influence and his active guidance in classroom teaching will raise students' interest in learning. This study provides a more comprehensive basis and clues to improve students' interest in learning and education reform.

This study was aimed to compare the difference of parameters of texture feature in the transverse section images of the same and different Chinese herbal medicine. A total of 26 parameters of herbal medicines were ex-tracted by gray-level co-occurrence matrix and grayscale gradient matrix. The graph of mutative curve was drawn. And differences of 26 parameters of texture feature in the same and different Chinese herbal medicine were com-pared. The results showed that parameters of texture feature extracted by gray-level co-occurrence matrix and grayscale gradient matrix had similarities and differences in the same and different Chinese herbal medicine. It was concluded that the method can show the texture feature scientifically and quantitatively. It also laid a foundation for the establishment of an automatic identification model, but the parameters still had instability. All these remind us to find some parameters which can show the details of texture feature preferably, thus perfect the extracted method of texture features in Chinese herbal medicine.

This study was aimed to explore the impact of integrality of Chinese herbal medicine on parameters of tex-ture feature in transverse section images. Three Chinese herbal medicine of Semen Arecae, Radix et Rhizoma Rhei and Radix A tractylodis Macrocephalae with different texture features were taken as research materials. Parts of Chi-nese herbal medicine were cut off from the whole by equal proportions. The 26 parameters were extracted by gray-level co-occurrence matrix and grayscale gradient matrix. The similarities and differences of 26 parameters of texture feature in the parts and whole, rectangular and fan-shaped Chinese herbal medicine were compared. The results showed that parameters of Semen A recae and Radix et Rhizoma Rhei with radial or annular texture had better con-sistency in whole and fan-shaped parts. Parameters of Radix A tractylodis Macrocephalae with irregular texture fea-ture were approximately the same in the whole and rectangular parts. It was concluded that whether parameters of texture features in parts Chinese herbal medicine can present the whole were related to its texture feature and the shape of the parts. This study provided the basis for collection of Chinese herbal medicine when sampling images. It also laid a foundation for the extraction of accurate parameter of texture feature.
