Objective To explore the clinical efficacy of motor imagery therapy in treating neurogenic bladder dysfunction after traumatic spinal cord injury (SCI).Methods Seventy patients with neurogenic bladder control problems after SCI were randomly divided into an experimental group and a control group using a random number table.All patients of the two groups were given general bladder function intervention,including intermittent catheterization,inducing voiding by reflex detrusor contraction,Credé's maneuver urination,etc.Additionally,the patients in the experimental group were given supplemental motor imagery therapy.The times of urinary incontinence,average bladder capacity,maximum voided volume and residual urine volume of the two groups were measured before treatment and at 2 months after treatment.The two groups' outcomes were quantified using a quality of life (QOL) score.Results Incidents of urinary incontinence,average bladder capacity,residual urine volume,voided volume and the QOL score showed significant improvements in both groups,but the experimental group showed better improvements than the control group.The differences were statistically significant.Conclusion The combination of general bladder function intervention with motor imagery therapy can improve the voiding function of patients with neurogenic bladder disorders after SCI more significantly and enhance their QOL.

ObjectiveTo explore the value of differential diagnosis between pigmented villonodular synovitis (PVNS) and rheumatoid arthritis (RA) in active stage with clinic and ultrasound. MethodsWe analyzed retrospectively the characters of clinic and ultrasound of sixteen patients with PVNS and sixteen patients with rheumatoid arthritis inactive stage.ResultsIn aspects of patient’s age (T=185), pain scores (T=136) history of trauma (P=0.029), functionally uncompensated conditions (P=0.001) type (P=0.000) and sum (P=0.000) of involved joints、bright spot-echoes in hydrops (P=0.001) tendons nearby involved (P=0.001) and the Adler’s grade of Doppler ultrasound blood flow (P=0.009), the differences between PVNS and RA in active stage had statistical significance (P<0.05). Clinic characters: patients with PVNS were younger, often had a history of trauma. But patients with RA in active stage had a higher pain score and functionally uncompensated condition. Ultrasound characters: big and single joints were often involved in patients with PVNS, and tiny bright spot echoes could be detected in hydrops. Instead, big and small, multiple joints, tendons nearby were often involved in patients with RA, who had a higher ratio of gradeⅢ Doppler ultrasound blood flow. And in aspects of sex, the presence of hydrops and synovium thickness, the differences between the two had no statistical significance (P>0.05).ConclusionThe clinical characters including Patient’s age, pain scores, history of trauma, functionally uncompensated conditions, and the characters of ultrasound including type and sum of involved joints, bright spot echoes in hydrops, tendons nearby involved and the Adler’s grade of Doppler ultrasound blood flow, are helpful for the differential diagnosis of PVNS and RA in active stage.

Objective Glycodelin-A is one of glycoproteins secreted from endometrial epithelial cells , and it plays an im-portant role in embryo implantation , inhibition of reject reaction and pregnancy maintenance .Glycodelin-A will become an important potential marker in evaluating the endometrial receptivity and predicting the pregnancy outcome .The aim of this study was to investigate the correlation of glycodelin-A detected on the day of HCG and endometrial receptivity and the effects of glycodelin -A on the pregnancy outcome in the intrauterine insemination (IUI) period. Methods One hundred and seven woman patients with bilateral unobstruct-ed tubes and without endometrial lesions , endometrial polyps or intrauterine adhesions from Oct 2012 to Feb 2014 in our hospital were recruited in this study .Serum glycodelin-A in women receiving IUI on the day of HCG was measured by ELISA .Serum estradiol (E2), progesterone (P), and corpus luteum (LH) levels were measured by immunochemiluminometric assays .The condition of the endometrium was examined by transvaginalultrasonography . Results The serum glycodelin-A level on the day of HCG was higher in pregnant group [(1.47 ±0.38)ng/mL] than that in nonpregnant group ([0.62 ±0.13]ng/mL).The serum glycodelin-A level on the day of HCG was higher in endometrial thickness ≥7 mm group ([1.53 ±0.49]ng/mL) than endometrial thickness <7 mm group ([0.51 ±0.17]ng/mL). Conclusion The serum glycodelin-A level on the day of HCG may reflect endometrial receptivity to a cer-tain extent , which might have prognosis value for pregnancy following IUI .

The protein production system using a baculovirus Antheraea pernyi nucleopolyhedrovirus (AnpeNPV) as a gene expression vector and its host insect as a natural bioreactor was successful established and its excellent performance in the protein production has been demonstrated. In this paper, the system is used to produce recombinant human epidermal growth factor (rhEGF), which have been widely used in medical and cosmetic treatment. A recombinant AnpehEGF virus has been constructed by replacing the viral polyhedrin gene with the rhEGF gene, and then injected it to Samia cynthia ricini pupae. Amplification and expression of rhEGF gene in the pupae was clearly detected by PCR, Western blot and ELISA analyses. These analyses have also revealed that rhEGF in the pupae was significantly increased at 6 days post-infection, and reached maximum level at the 12th day. The concentrations of rhEGF were 19.77, 24.90, 618.59 and 1 952.46 ng/g pupae at 3, 6, 9 and 12 days post-infection, respectively. However, the rhEGF concentration reduced at later stage (days 15). The rhEGF in the pupae could be purified using ammonium sulfate precipitation and Ni-NTA agrose affinity chromatography. Results demonstrate that Samia cynthia ricini pupae can be used as a bioreactor to produce rhEGF and, if successfully improved, will be a novel method of rhEGF production with lower cost and more efficient.

OBJECTIVEThis study aims to investigate the gene mutational characteristics of cathepsin C (CTSC) gene in a Chinese patient with Papillon-Lefèvre syndrome (PLS), then further confirm the genetic basis for the phenotype of PLS, and obtain genetic information that can be used as guide in the diagnosis and treatment of PLS.

METHODSWith their consent, peripheral blood samples were obtained from the proband and his family members (his parents and older sister) for genomic DNA extraction. The coding region and exon/intron boundaries of the CTSC gene were amplified and sequenced using poly-merase chain reaction and direct sequencing of DNA.

RESULTSCompound heterozygous mutations of CTSC gene were iden-tified in the patient. The proband carries one heterozygous nonsense mutation c.754C>T in exon 5 and one heterozygous missense mutation c.1040A>G in exon 7. Both parents were heterozygous carriers without the clinical symptoms of PLS. None of the mutations were detected in the proband's sister.

CONCLUSIONSThe study proves that mutations of CTSC gene are responsible for the phenotype of Papillon-Lefèvre syndrome.
