OBJECTIVE To investigate and analyze the hospital infection in 32 hospitals throughout the county,in order to reduce hospital infection. METHODS According to new Hospital infection administration regulations and medical service hospital infection control quality evaluation requirements,we had investigated and analyzed and guidanced to improve the hospital infection management in 32 hospitals of the county for a two-years. RESULTS The monitoring,surveillance and management of hospital infection in grass-roots hospitals as a quality evaluation index of hospital medical service still had many problems,After two years,it had been more improved the quality in the field of administration management,sterilization and disinfection,surveillance and sevage treatment. CONCLUSIONS According to Hospital infection administration regultions it is important to strengthen the hospital infection management for guaranteeing the grass-roots hospital medical service quality and medical care safety.

The stress resistance of Saccharomyces cerevisiae industrial strains for molasses to high-concentration ethanol,high temperature,high osmotic pressure,furfural toxicity,phenol toxicity,acetic acid toxicity and G418 toxicity were analyzed by the spot dilution growth assays in this paper. The results showed that the stress resistances among these industrial strains were obviously different. The strains AS2.1189 and AS2.1190 are more resistant to the tested stress factors than any others .The strain 396 is the most resistant to the acetic acid toxicity and G418 toxicity,and the strain 2610 is the most resistant to the high temperature.

Objective To explore the causes and treatment of gastrointestinal complications after anterior approach for thoracolumbar fracture and dislocation.Methods A retrospective analysis was carried out in 153 cases with thoracolumbar fracture and dislocation undergone anterior approach from Jan- uary 1999 to October 2003.Postoperative gastrointestinal complication was seen in 15 cases including sev- en with dynamic intestinal obstructions,three with stress ulcer,three with intestinal bacteria imbalance, one with tuberculosis peritonitis resulted from dissemination of primary tuberculosis,and one with acute relapse of chronic appendicitis.Results All patients were effectively cured by using corresponding methods in regard of different causes.Conclusions(1)Gastrointestinal complications following ante- rior approach for thoracolumbar fracture and dislocation are mainly resulted from following causes,ie,se- rious primary trauma,primary gastrointestinal vegetative nerve injury or that caused by surgical operation, intraoperative contusions of abdominal viscera,postoperative retroperitoneal hematoma,acute lesion of gastric mucous membrane as well as imbalance of intestinal flora.(2)Correct treatment of primary trau- ma,meticulous operation,reasonable utility of antibiotics and appropriate management can effectively prevent and control gastrointestinal complications.

Objective To explore the accuracy of double modality fusion between CT and MRI for human head, based on pair anatomical points registration. Methods CT and MRI were approached in 4 patients, digital imaging and communications in medicine (DICOM) files were loaded on 3D Slicer (version 4. 8. 1), the surface and brain were reconstructed automatically with volume rendering as reconstructed models, 10 surface characters were tested with localization error and would be used as fiducial points, 8 of the points would be chosen as pair-points for registration according the localizing error after 5 localizations, 5 registration groups based on 4, 5, 6, 7, 8 fiducial points were divided. Singular value decomposition (SVD) was employed for registration as a basic algorithm, and fiducial registration error (FRE) was used to evaluate the registration error. Results FRE values of double modality fusion were 2. 68-6. 54 mm. FRE values of 4, 5, 6, 7, 8 fiducial points were (5. 14± 0.97) mm, (4. 71 ±0. 64) mm, (4. 45±0. 59) mm, (4. 13± 0. 55)mm, (3. 54±0. 72) mm respectively. There was no statistical difference between neighbor groups, while in 4 and 8 points groups, the FRE values were different statistically. Conclusion Surface anatomic characters can be used for double modality fusion between CT and MRI; FRE values after CT-MRI double modality fusion are reduced with the increase of points.

Objective　To investigate the validity of the Chinese version of the Symptom Check-List-90 (the SCL-90) in Chinese population. Methods　A total of 624 normal person and 268 out patients were examined with the SCL-90. Results　（1）The internal consistency of the original subscales was found to be good and Cronbach's coefficient alpha ranged from 0.78 to 0.90; （2）Discrimination function analysis based on the 9 original subscales showed that the power of the SCL-90 in discriminating the patients and the community was good with a corrective rate of 80.6%; （3）Factor analysis on the items of the questionnaire yielded a very strong un-rotated first factor which could represent other factors; （4）High inter-correlations were found between the 9 original subscales of the SCL-90 with a correlation coefficient ranging from 0.39 to 0.79. Conclusion　(1) The SCL-90 is acceptable as a research setting and psychiatric screening inventory; (2) The SCL-90 does not have potential as an inventory to distinguish different diagnostic groups; (3) The SCL-90 is not a multidimensional inventory.

Surgical resection of liver diseases such as liver cancer,traumatic hepatic rupture,it was often faced with ischemia-reperfusion injury of the residual liver,which significantly increased the risk of surgical treatment and impact the postoperative recovery of patients.Autophagy was a way of programmed cell death after hepatic ischemia reperfusion.When researching hepatic ischemia-reperfusion injury simulated by animal experiments,it ofen detected the level change of autophagy marker molecular LC3-Ⅱ representing the activity of cell autophagy.Now the authors write the research progress of LC3-Ⅱ in hepatic ischemia-reperfusion injury.

AIM: To analyze the associated factors of poor vision after phacoemulsification operation.
METHODS:Clinical data of cases with poor vision after cataract phacoemulsification combined with IOL implantation from 341 patients(418 eyes) during Jan. 2015 to Jan. 2016 in our hospital were collected and logistic correlation analyzed.
RESULTS: The incidences of postoperative low vision were 10. 3% for one month after operation. Forty-three eyes were reported low vision, and 41 of 43 the patients with postoperative low vision had fundus oculi disease before operation, which included 20 eyes ( 48. 8%) with age-related macular degeneration, 16 eyes(39. 0%) with diabetic retinopathy, 3 eyes ( 7. 3%) with glaucomatous optic neuropathy, 1 eye(2. 4%) with pathologic myopia of retinopathy and 1 eye ( 2. 4%) with branch retinal vein occlusion.
CONCLUSION: The associated factors of poor vision after phacoemulsification operation are preoperative eye diseases and the nuclear hardness, and preoperative eye diseases may be the main causes of postoperative low vision. Comprehensive examination should be attached importance to, and be careful in the operation to decrease the harm for visual performance.

Human genne myo-inositol monophosphatase 2(IMPA2) was recently a novel and promising gen that was associated with disease,especially in mental and neuro diseases.Its locus is in chromosome 18p11 2,about 15 kb.It encodes IMPA2 enzyme.IMPA2 enzyme as a mainly and catalytic inositol plays an important role in cell signaling system.The mechanism of action of IMPA2 gene is still unclear.But in basic research on genetic structure and IMPA2 product,the biochemical functions and crystal structure have gradually been recognized;In the clinical application,the association with disease has been detected in manic depression,schizophrenia and febrile seizuers.IMPA2 even has been a susceptible gene to certain diseases.IMPA2 has increasingly been the hotspot in gene research.
