OBJECTIVETo discuss the treatment strategy of acetabular fractures and unstable pelvic fracture of the hip and to evaluate its outcome.

METHODSRetrospective analysis of clinical data in 32 patients with unstable pelvic fracture and acetabular fractures from January 2007 to June 2013 were collected. There were 18 males and 14 females aged from 18 to 62 years old (means 38 years old). According to Tile classification of pelvic fracture, 11 cases were type B1, 8 were type B2.1, 7 were type B2.2, 3 were type C1.1, 2 were type C1.2, 1 was type C3. According to Judet-Letournel classification, anterior column fracture was in 1 case, transverse fracture in 8, transverse plus posterior wall fracture in 6, T-type fracture in 1, anterior column plus half transverse fractures in 5, double column fracture in 11. Other combined injuries were treated early, the surgical operation were performed after stable condition. The hip joint function and the fracture reduction were assessed during follow-up.

RESULTSThe operative time was from 1.8 to 6.5 hours (averaged 3 hours). Two fat patients' incision occurred in fat liquefaction and healed after dressing, no incision infection happened. Only 1 case was lost to follow-up, 31 patients were followed up with a mean time of 23 months (6 to 42 months). The healing time of pelvic fracture was from 8 to 18 weeks (averaged in 10.6 weeks). The hip function was evaluated according to the Matta and Tornetta standard postoperatively, the result was excellent in 15 cases, good in 14 cases, fair and poor in 1 case respectively. The Majeed score of the hip function was 83.65? 7.67, the result was excellent in 15 cases, good in 12 cases and fair in 4 cases. The healing time of acetabular fractures was from 8 to 16 weeks (averaged in 10.2 weeks). The fracture reduction was assessed by Matta standard, the result was excellent in 15 cases, good in 12 cases and fair in 4 cases. The heterotopic ossification was evaluated by Brooker standard, 4 cases were grade I, 1 case was grade II . There were no infection, nonunion and necrosis of the femoral head in all patients. The nerve damage symptoms in 5 patients disappeared during 4 to 6 months after operation.

CONCLUSIONPatients with unstable pelvic fractures and acetabulum fractures were in a critical condition early, using the concept of damage control to save lives in a timely manner. Grasp the operation time in the late treatment, acetabulum fractures reach anatomical reduction as far as possible, pelvic fractures are given priority to stable reconstruction. The operation order was fixed pelvic ring first, according to the condition to choose the appropriate surgical approach and fixed mode.

ObjectiveTo determine the cerebral protection effect and mechanism of propofol on global cerebral ischemia and reperfusion damage in rats.Methods19 adult male Wistar rats were randomly divided into 3 groups, ischemia group (n=7), propofol group (n=7), and sham injury group (n=5). Global cerebral ischemia and reperfusion model were made by means of Pulsinelli's method. Rats in propofol group were anesthesia with propofol at the dosage of 1.5 ml/h for 30 min at the beginning of reperfusion. Apoptosis and necrosis rate were detected by cytometry. In the same time, bcl-2, Bax and p53 protein expression in hippocampus neurons were detected. ResultsThe apoptosis and necrosis rate in propofol group were significantly decreased as compared with ischemia group ( P<0.05). Bax and p53 protein expression in hippocampus neurons were also significantly decreased as compared with ischemia group (P<0.05), however, no significant findings in bcl-2 protein expression (P>0.05).ConclusionPropofol can decrease apoptosis and necrosis rate in cerebral ischemia reperfusion injured neuron, and the mechanism maybe related to decreasing the expression of Bax, p53 protein.

Objective To understand the current situation of occupational exposure and occupational safety attitudes among nursing students in Kunming Medical University, and to find effective interventions to improve nurses' occupational safety,and to reduce occupational exposure.Methods 854 students in Kunming Medical University were investigated by a questionnaire survey, including Demographic characteristics, Occupational exposure conditions, Occupational safety attitude and Gathers, quit intention . The correlations between occupational safety attitudes and occupational exposure were analyzed with Simple Linear Correlation.Results There were 94.30%female respondents,and only 5.70%male respondents.The average age of respondents was 22.52±2.90 years. The Simple Linear Correlation analysis showed that correlation between Negative attitude and occupational exposure was positive correlated, the occupational exposure and Support from managers, and Optimistic were negative correlation ( <0.05) .Conclusions Occupational safety and attitude are related to occupational exposure. Nursing students should apply standardized operation to improve the professional quality and ability. Schools should strengthen the education of occupational protection for nursing students. Hospital management should regularly organize nurses to study occupational exposure protection knowledge,give full affirmation of the nurse's achievements in the work, and offer certain reward appropriately.

OBJECTIVE To investigate whether the KCNN4 gene and KPTN gene contribute to a Chinese non-syndromic hearing loss pedigree linked to DFNA4 with positional candidate approach. METHODS The complete coding region of the two genes were amplified with polymerase chain reaction (PCR), and bidirectional sequencing of the PCR products was subsequently applied in the 36 family members to identify the possible mutations or polymorphisms in the candidate genes. RESULTS Sequence analysis of coding regions and splice sites of the two candidate genes in 36 members including 12 hearing-impaired individuals in family Z002 failed to demonstrate any deafness-causing mutations of KCNN4 gene. There was one heterozygous mutation identified in exon10 coding sequence (942C/T) of KPTN gene, which did not result in amino acid change (P302P) as a repoerted synonymous SNP site (rs2293424). This SNP site did not cosegregate with the phenotype of family Z002. CONCLUSION Our study excluded the two candidates, KCNN4 and KPTN , as the causative genes involved in this Chinese DFNA4 pedigree.

Objective The purpose of this paper is to screen inborn errors of meta bolism (IEM) by analyzing urinary components, so as to provide laboratory guide for their diagnosis and therapy.Methods Urine samples of patients suspected to have IEM were collec- ted.Urea was de compo sed with urease and n-heptadecanoic acid was added as internal standard.Protein was denatured with ethanol and precipitate was removed by centrifugation,dried b y evaporation, the residue was trimethylsilylly derivatized with BSTFA/TMCS,and then analyzed with GC-MS for quantification of organic acids, amino acids,suga rs, polyols, purines and pyrimidines, simultaneously. This procedure is denom inated as urease pretreatment-gas chromatography-mass spectrometry (UP-GC-MS) internationally.Results Urinary samples of 327 patients from 6 provinces, cities and autonomous regions were analyzed,and 16 kinds of 27 cases of IEM were screened out with a positiv e rate of 8.26%,among which there were 3 cases of hyperphenylalaninemia,3 cases of glyceroluria,3 cases of Leigh syndrome, 2 cases of propionic acidemia, 2 case s of methylmalonic aciduria, 2 cases of von Gierke′s disease, 2 cases of fructo se-1,6-diphosphatase deficiency, 2 cases of fructosuria, 1 cases of multiple car boxylase deficiency, 1 cases of glutaric acidemia typeⅠ, 1 cases of maple sy rup urine disease, 1 cases of hyperglycinemia, 1 cases of 3-aminoisobutyric acid uria,1 cases of adult-onset typeⅡcitrullinemia,1 cases of galactosemia and 1 ca ses of Fanconi′s syndrome.Several IEM patients above had died,but satisfactory therapeutic effects had been achieved in some diseases,in cluding multiple carboxylase deficiency,methylmalonic aciduria and galactosemia. Other patients′ condition remained to be followed up.Conclusion Analysis of urinary components by UP-GC-MS provides a valuable tool for screenin g of IEM and the results will help to provide effective diagnostic and therapeut ic guide for the patients.

OBJECTIVETo investigate the anti-proliferation effect of tyrosine protein kinase inhibitor, Genistein, on human salivary adenoid cystic carcinoma cell line SACC-83, and its effect on Survivin expression.

METHODSSACC-83 cells were treated with different concentration Genistein for different time, cell survival rate was calculated with MTT assay, apoptosis was detected with flow cytometry, the expression of Survivin was quantitatively analyzed by Western blotting and FluorChem V2.0 software.

RESULTSWhen treated with Genistein of certain concentration for certain time, SACC-83 cell growth was significantly inhibited. With the increase of concentration and elongation of acting time, the inhibitory effects increase. Treated with 220 micromol/L Genistein for 72 hours, SACC-83 cell growth was significantly inhibited, cell apoptosis was induced (P < 0.01), and the expression of Survivin decreased.

CONCLUSIONGenistein inhibits the growth of human salivary adenoid cystic carcinoma cell line SACC-83, and induces cell apoptosis; the decrease of Survivin expression may be one of the mechanisms of Genistein inducing apoptosis.

Objective To investigate the effect of depression symptoms on surgical outcome of posterior decompression among cervical spondylotic myelopathy (CSM) patients. Methods Between October 2006 and October 2011 in our hospital, lami?nectomy or laminoplasty was performed in 396 cases that were enrolled in the study. There were 132 males and 264 females with an average age of 60.2 years(ranged,39-84 years). All patients were divided into depression group and non?depressed group by the 21?item Beck Depression Inventory (BDI). There were no statistically significant differences between groups in age, sex, smok?ing status, duration of symptoms, and employment status (whether in the current working). The Japanese Orthopedic Association (JOA) scores, Neck disability index (NDI) and visual analogue scale (VAS) were compared after 1.5 months postoperatively. Re?sults All of 396 cases were followed up. The mean follow up duration was 32 months (range,24-50 months). There were no statistically significant differences in the CCI decline (7.1%±2.1% versus 6.8%±1.5%), expansion degree[(130.9±7.0) mm2 versus (150.8 ± 5.2) mm2] and the drift?back distance of the spinal cord [(5.7 ± 1.2) mm versus (6.2 ± 0.8) mm]. However, pa?tients with continuous depression showed poorer improvement than non?depressed patients in the surgery outcome: JOA im?proved (1.42±0.56 versus 6.76±3.12); NDI declined (7.31±2.18 versus 21.11±11.36); and VAS lightened (16.08±19.76 versus 23.85±20.79). Conclusion Depression contributed a dissatisfied surgery outcome after posterior decompression on functional re?covery, disability index and pain scores among patients of the cervical spondylotic myelopathy.
