Occupational Therapist Registered (OTR) Exam is established and managed under the national certification body for occupa-tional therapy professionals-National Board for Certification in Occupational Therapy (NBCOT). The OTR Exam is designed based on reg-ular practical analysis on the entry-level front-line occupational therapists in the United States, conducted by the Certification Examination Development Committee (CEDC). The panel will follow four steps, including drafting the exam blueprint, designing the questions, rounds of discussion and validation and finally putting the questions into confidential question bank for random selection by computer during exam. The OTR Exam is featured by its close relevance and update with clinical status of the States, high-standard professional requirement based on broadest public consensus within the profession as well as its evidence-based and scientific procedure throughout the designing process, which may benefit the development and standardization of Occupational Therapy Profession in China.

Objective To explore diagnosis,treatment and prognosis of intestinal atresia(IA) in neonates,so as to increase the healing rate.Methods Surgical treatment was given to 29 cases of congenital IA from Apr.2004 to Nov.2008.Comprehensive analysis was carried out on clinical manifestations and flat X-ray.All cases were with vomiting,15 cases were with normal fetal faeces.Stomach and intestinal atresia were observed in the upper abdomen in 19 cases,fluid levels in generous stomach and expended intestines were seen in 21 cases by X-ray.All children underwent operation,including ileum atresia(16 cases),duodenal atresia(7 cases),and jejunal atresia(6 cases).The types of atresia were type Ⅰ(9 cases),type Ⅱ(9 cases),type Ⅲa(9 cases),type Ⅲb(1 case) and type Ⅳ(1 case).Nine cases were treated with septum resection and then anastomosed longitudinally,3 cases underwent end-to-end anastomose and 17 underwent end-to-back anastomose.All cases were served in intravenous hyperalimentation.Results All cases lived postoperatively,and 1 child gave up for postoperatively treatment.Twenty-eight cases were cured.There was 1 case of obstruction of anastomatic,and was cured by non-operatively treatment.There was no anastomatic leakage and wound disruption.Twenty-six cases were followed up for 3 months and up to 4 years.These symptoms had no relapse.Conclusion Early diagnosis,appropriate surgical procedure and surrounding operation management are crucial for improving the cure rate.

AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

Objective To investigate the changes in the expression of keratin genes in renal tissues during renal ischemia-reperfusion (I/R) injury in mice.Methods Six wild type male C57/B6 mice,aged 50 days,weighing 20-30 g,were divided into 2 groups (n=3 each) using a random number table:sham operation group (Sham group) and I/R group.Right renal arteries and veins were clamped for 1 h followed by reperfusion,and the left kidneys were removed to establish the model of renal I/R injury.At 24 h of reperfusion,blood samples were collected from the left ventricle for determination of serum creatinine and urea nitrogen concentrations by colorimetric method.The right kidney specimens were obtained for pathologic examination and for determination of the expression of kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin mRNA (by quantitative real-time polymerase chain reaction [qRT-PCR]) and keratin genes (by Affemetrixc DNA microarray).The differentially expressed genes identified were further confirmed by qRT-PCR.Results Compared with Sham group,the serum creatinine and urea nitrogen concentrations were significantly increased,the expression of kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin mRNA was up-regulated (P＜0.05),and the damage to the renal tubules was aggravated in I/R group.The results of microarray analysis showed that only keratin 20 gene (the expresion was up-regulated) was the differentially expressed gene (P＜0.05),and the results measured by qRT-PCR were consistent with those measured by Affemetrixc DNA microarray.Conclusion Keratin 20 gene expression in renal tissues is up-regulated during renal I/R injury in mice,and the change may be involved in the endogenous protective mechanism during renal I/R injury.

This study descriptively illustrated the definition of certified hand therapist, eligibility requirement and accreditation system based on the official guidelines from American Society of Hand Therapists (ASHT), Hand Therapy Certification Commission (HTCC) and Handbook of Certified Hand Therapy Examination. Besides, this exam was compared with National Physical Therapy Examination (NPTE) and Occupational Therapist Registered Examination (OTR Exam). The testing domains and contents may help the domestic teaching faculty to standardize the course syllabi, promote divided development of physical therapy and occupational therapy in a specialized manner, and ex-erted positive impact for promoting establishment of the hand specialists and accreditation system of China itself.

Biosurfactants (BSs) are highlighted owing to their multiple advantages in diverse applications. To screen a superior strain that producing a blend-biosurfactant of lipopeptide and glycolipid, the hemolytic activity assay on blood agar plates, the modified oil-red spreading test and MALDI-TOF Mass Spectrometry identification of the purified products was carried out. Bacillus subtilis THY-7 was selected and its principal products were surfactin and dirhamnolipid. The medium component and culture conditions of THY-7 were optimized by both single factor and orthogonal experiments. After 48 h optimal batch culture in flask, the cell density (OD600) was 37.0 and the product titer was 2.4 g/L, which was 3.4 folds and 3.1 folds of that under original condition, respectively. A fed-batch culture in a 5 L fermentor was further performed coupling with in situ recovery of foam, in which the titer of blend-BS increased to 4.5 g/L at 25 h. Quantification by HPLC and anthrone colorimetry revealed that surfactin and dirhamnolipid accounted for 74% and 22% of the blend-BS, respectively.

OBJECTIVETo investigate the association of male reproductive tract infection (RTI) with semen parameters and sperm DNA damage.

METHODSWe classified 1 084 males attending the infertility clinic into an RTI group (n = 300) and a non-RTI control group (n = 784). According to the WHO standards, we obtained routine semen parameters, detected sperm morphology, and determined the sperm DNA fragmentation index (DFI) by sperm chromatin structure assay.

RESULTSThere were statistically significant differences between the RTI and control groups in the semen volume ( [2.58 ± 1.20] vs [3.00 ± 2.10] ml), grade a + b sperm ([50.6 ± 17.2] vs [53.2 ± 15.8]%), grade d sperm ( [39. 8 ± 17.8] vs [36.5 ± 16.2]%), and total sperm count ([218.5 ± 185.0 ] vs [278.5 ± 375.5 ] x 10(6)/ejaculate) (all P < 0.05), but not in the males' age, sperm concentration or pH value (P > 0.05). The percentage of morphologically normal sperm was significantly lower ([3.46 ± 2.90] vs [4.61 ± 3.60%, P < 0.05) but the DFI was markedly higher in the RTI group than in the control ([19.4 ± 11.4] vs [15.2 ± 8.8]% , P < 0.01). The percentage of the cases with DFI > 30% was remarkably higher (13.0 vs 5.74% ) while that of the cases with DFI < 10% dramatically lower in the former than in the latter (16.0 vs 28.0%). The level of seminal plasma elastase was correlated negatively to sperm concentration, sperm count, and the percentage of morphologically normal sperm (P < 0.05) but positively to DFI and grade d sperm (P < 0.05 or P < 0.01).

CONCLUSIONMale reproductive tract infection not only affects semen parameters and sperm morphology but also causes serious sperm DNA damage.
