Objective To investigate the clinical efficacy of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery for patients at the early stage of traumatic brain injury (TBI). Methods 72 patients with TBI hospitalized from January, 2013 to October, 2014 and 30 healthy controls matched gender, age and educational background were assessed with the Chinese version of LOTCA battery and Mini-Mental State Examination (MMSE) respectively. Results The score of MMSE and LOTCA were correlated (r=0.56, P<0.01). Compared with the controls, the scores of all the subtests of LOTCA decreased (P<0.01) in the patients, especially the orientation, visuomo-tor organization and thinking operation;with the more incidence of medium and serious dysfunction of all the subtests of LOTCA except perception (P<0.01), in which thinking operation was the most and attention was the least. The area under the receiver operating curve (ROC) was (0.84±0.04) in LOTCA, less than that of (0.91±0.03) in MMSE (P<0.05). Conclusion Cognition is widely impaired in patients after TBI, most involved thinking operation. LOTCA is less effective to identify cognitive dysfunction than MMSE, and can be used as an al-ternation or a supplement.

OBJECTIVE To investigate the factors influencing the effects of disinfection of HBV on dental hand piece. METHODS After polluted with HBV positive serum,the dental hand piece was disinfected with sterilizer at the condition of 134℃ for 5 minutes according different treatment procedures.The samples were then taken and detected HBsAg by the automatic enzyme immune analyzer using the third generation EIA agent.The efficacy of disinfection of HBV was presented by the reaction of HBsAg detection. RESULTS If the dental hand piece was sterilized directly not cleansed using clean water after pollution and dried in room temperature,there were 96.87% of the samples being HBsAg positive,and the polluted but dried hand piece,even cleansed there were 87.5% of positive result, even if prolonged the time of sterilization and the frequencies of vacuumization,the HBsAg positive rate of the sample was still up to 56.25%.But if the hand piece was irrigated and cleansed immediately after pollution and sterilized,all samples were HBsAg negative. CONCLUSIONS Whether or not cleansed immediately is the most important factor influencing the efficacy of hand piece sterilization after pollution.

Objective To test the reliability and validity of the Chinese version of the John Hopkins Adapted Cognitive Exam ( ACE) in NICU patients. Methods The English ACE was translated and adapted into the Chinese version . Cognitive functions of 40 critically ill patients in NICU were assessed with the Chi?nese version of ACE and MMSE battery.The scores of ACE and MMSE were analyzed to test the content va?lidity,construct validity,concurrent validity,internal consistency,inter?rater reliability and test?retest reliabil?ity.Result The correlation coefficient between each factor and the total score ranged from 0.617 to 0.938, and the content validity was good.The ACE was significantly correlated with MMSE( r=0.822, P<0.05). Five factors were extracted by main principle analysis, the cumulative contribution was 85. 90%, the factor loading of each item was all over 0.5,the scale had good construct validity.There existed a good internal con?sistency ( Cronbach’ α=0.756 ) as well as a good inter?rater reliability ( ICC>0.95) and test?retest reliabil?ity (ICC=0.652?0.979) of the Chinese version of ACE.Conclusions The Chinese version of ACE has been proved to be a reliable and valid screening tool for cognitive impairment in NICU patients.

OBJECTIVE: To explore the forensic application value of detection of matrix metalloproteinase-11 (MMP-11) in menstrual blood by enhanced chemiluminescence method. METHODS: Menstrual blood, vaginal swab, peripheral blood, saliva stain, urine stain and semen stain were collected to detect whether or not there were MMP-11 using enhanced chemiluminescence method. The specificity and reliability of the MMP-11 assay along with its sensitivity were evaluated. RESULTS: The positive detection rate of MMP-11 in menstrual blood was 89.47%, whereas no MMP-11 was found in vaginal swab, peripheral blood, saliva stain, urine stain and semen stain. When 25 microL sample was added, the mass concentration of protein was 1.329 microg/microL, then MMP-11 could be detected. A positive detection rate of 89.58% was observed in MMP-11 positive menstrual blood samples after stored at 4 degrees C for 20 months. CONCLUSION Enhanced chemiluminescence method is sensitive and specific for detecting MMP-11, and can be applied to distinguish menstrual blood from common stain such as peripheral blood, vaginal fluid.

OBJECTIVE: To prove the feasibility of detecting menstrual blood as well as its cellular localization with rabbit-anti-human matrix metalloproteinase-11 (MMP-11) polyclonal antibody. METHODS: MMP-11 in menstrual blood, peripheral blood, vaginal liquid, aged menstrual bloodstain, and endometrium sections were assayed with SAP immunohistochemistry. RESULTS: MMP-11 was found only in menstrual samples within stroma and epithelium cells. CONCLUSION MMP-11 polyclonal antibody may be applied in the distinction between menstrual blood and venous blood.

OBJECTIVETo investigate the effect of short hairpin RNA (shRNA) targeting N-acetylglucosaminyltransferase V (GnT-V) on the proliferation of prostate cancer PC-3 cells.

METHODSLipofectamine 2000 was used to transfect the recombinant plasmids carrying the shRNA targeting GnT-V gene into PC-3 cells. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to measure the mRNA expression of GnT-V, and CCK-8 assay was used to measure the cell proliferation after the transfection.

RESULTSThe recombinant plasmids were successfully transfected into PC-3 cells, resulting in a reduction of GnT-V mRNA expression by 73%. The proliferation of PC-3 cells was significantly inhibited after the transfection.

CONCLUSIONThe shRNA targeting GnT-V gene can reduce the expression of GnT-V mRNA and inhibit the proliferation of PC-3 cells in vitro.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.
