[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

Objective: Blue dye was one of the methods for sentinel lymph node biopsy in breast cancer, but the success rate was affected by multiple factors. This study was to determine the related factors contributing to the success of sentinel lymph node biopsy in breast cancer using blue dye method. Method:From Jan. 2007 to Aug.2008, sentinel lymph node biopsy was performed by periareolarly injecting 1% methylene blue in 141 breast cancer patients followed by axillary clearance. Pathological diagnosis was performed for all of the lymph nodes by conventional HE staining. Unconditional logistic regression was applied to make both univariate and multiva-riate analysis. Results:Sentinel lymph node was successfully detected in 126 patients. But the biopsy was failed in the 15 patients. The success rate was 89.4% and the false negative rate was 6.82%. Univariate analysis showed that success rate of biopsy was in association with patients' age, body mass index (BMI), tumor size, preoperative axillary node's status, pathological grade as well as ≥4 positive axillary lymph nodes involved. Multivariate analysis indicated that the patients'age (OR=4.587, P=0.024), BMI (OR=4.882, P=0.011) as well as 4 or more of the axillary nodes involved (OR=3.143, P=0.013) were independent predicting factors for the success of sentinel lymph node biopsy. Conclusions:Methylene blue dyeing is a reliable method for sentinel lymph node biopsy. The rate of success is associated with patients' age, BMI as well as the number of metastases in axillary lymph nodes.

Four strains of aerobic denitrifying bacteria were isolated from biomembrane of the laboratory biofilter by selective medium. The denitrifying rates of these four strains were found more than 80% under aerobic condition for 40 hours. The denitrifying rate of A1 was highest, which was 99.05%. When measuring the course of nitrogen element changing, it is found that they accumulated nitrite expect the strain A1. The strain A1 was gram positive and spherical. It is identified as Pseudomonas putida based on its biochemical and morphological characters and phylogenetic analysis of 16S rDNA sequences(genbank accession NO.DQ836052.1). For the strain A1, the optimum beginning pH was 7.0 around, and the optimum tempera- ture was 30 ℃ around, The change of DO did not influence the effect of denitrification when it was more than 2.0 mg/L.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.
