Objective To evaluate parathyroidectomy combined with parathyroid tissue transplantation in forearm in the treatment of severe secondary hyperparathyroidism (SHP). Methods 9 cases treated with the procedure were reviewed.The diagnosis,operation indication and peri operative management were discussed. Results Thirty five hypertrophic parathyroids were resected from the 9 cases with SHP,and a left thyroidectomy was carried out for one case.Some parathyroid tissue has been grafted into the forearm for every patient.All of those grafts have survived.The symptoms va nished in all and the relevent laboratory tests recovered to normal after the surgery. Conclusions This surgical strategy is safe and effective for SHP not benefited from medical therapy.

Hydroxyapatite, as a biologically active material, has the same structure and ingredients as the inorganic of hard tissue in human body, moreover, its biocompatibility and biological activity of interface are better than other biological materials. Hydroxyapatite has been widely used in anophthalmus reconstruction, orbital reconstruction, artificial cornea transplant and drug carrier. Pure hydroxyapatite has some defects such as brittleness, low-bending strength, the strength of anti-fatigue and anti-sabotage in the physical environment are not high. In order to overcome or reduce these shortcomings, porous hydroxyapatite and composite hydroxyapatite are made to extent the clinical application of hydroxyapatite. With a variety optimization of performance, process and preparation of the composite materials, the hydroxyapatite/polymer tissue engineering materials in ophthalmology will be further developed.

Objective To investigate the incidence of prostatic utricle in hypospadias patients,and to assess the influence of enlarged prostatic utricle on ureteroplasty. Methods Physical examination,retrograde urethrography and urethrocystoscopy were performed for 52 in patients with hypospadias to investigate the incidence and degree of enlarged prostatic utricle and its relationship with the occurrence of fistula after urethroplasty. Results Prostatic utricle were demonstrated in 16 patients(31%).Of the 52 patients,the hypospadias was the glanstype in 5,peniletype in 8,peno scrotumtype in 20 and the perineumtype in 19.The incidence of enlarged prostatic utricle was 0/5,1/8,6/20 and 9/19 respectively.The occurrence of post operative fistula in simple hypospadias was 18.2%,and in the hypospadias complicated with enlarged prostatic utricle 46.7%. Conclusions The incidence and degree of enlarged prostatic utricle was increased according to the severity of hypospadias, and the occurrence of postoperative fistula was also increased as well.

Objective: To investigate the effect and mechanism of emodin (EMO) on human pancreatic cancer cell line BxPC-3 in vivo. Methods: After the pancreatic cancer model in nude mice was established, the mice were divided into four groups: control group (NS 0.2mL/d by i.p. injection), EMO group (EMO 40mg?kg-1?d-1 by i.p. injection), and Gemcitabine (GEM) group (GEM 80mg/kg, twice/week by i.p. injection) with 8 mice each group. After 2 weeks of administration, the mice were sacrificed, detected the body-weight change of nude nice before and after the experiment, and recorded the growth inhibition rate of tumor (TGI). Immunohistochemical (IHC) staining for ki-67 and terminal deoxynucleotidyl transferase-mediated nicked labeling assay (TUNEL) were undertaken to detect the cell proliferation and cell apoptosis in tumor tissue in xenograft nude mice. Results: The inter-group comparisons in body-weight of nude mice showed no significant difference in comparing group NS(27.0?1.64)g with group EMO(25.1?1.58)g and GEM(25.6? 1.47)g.The EMO group was 38.46%, the GEM group was 44.23%. The inter-group comparisons in immunohistochemical analysis of ki-67 showed significant difference in comparing group NS IOD(219.5?17.98) with group EMO IOD(146.6? 11.57)and GEM IOD(139.5?12.55), (P

Objective To develop a HPLC method for the determination of Lasiokaurin in the stems and leaves of Rabdosia nervosa.Methods HPLC was performed on a Kromsil C18 reversed-phase column(250mm?4.2mm,5?m).All of the reference substances and samples were separated with the mobile phase of methanol :water(55:45) under isocratic elution for 30min,flow rate was 1.0ml/min,the detection wavelength was 234nm,and the column temperature was 30℃.Results The content of Lasiokaurin was 0.005mg/g in the stems and 0.372mg/g in the leaves,the content in the stems were almost 1/75 times as much as that in the leaves.The average recovery of Lasiokaurin was 96.21%.Conclusion This developed method,which is simple and with good precision,high sensitivity and selectivity,can be used for quality evaluation of Lasiokaurin in Rabdosia nervosa.

Objective To determine the icariin content in Qianlie Shule Granules (QSG). Methods After proper pre-treatment,HPLC method was performed on a C18 column. The mobile phase consisted of acetonitrile-water (29 ∶71) and the UV d etective wavelength was set at 270 nm. Results The peak of icariin was separated completely. The calibration curve of icariin was linear within 0.16~1.2 mg?mL -1,Y=0.028 7X-0.009 62 (r=0.999 9). Conclusion This method is accurate and su itable for the determination of icariin content.

Objective To study the association of MIF-173 locus polymorphism and the risk of prostate cancer (PCa) in China. Methods A case control study including 259 PCa patients and 301 age-matched controls was conducted. The polymorphisms of MIF-173 locus were analyzed by poly-merase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique using genomic DNA isolated from peripheral blood lymphocytes. The correlations between the susceptibility to PCa and different genotypes were compared. The effect of age, smoking method and family history of canc-er were also analyzed. Results The rate of the MIF-173 * C variant allele of the PCa patients(n=259) was significantly higher than that of the controls (n=301) (36.0% vs 15.0%). The MIF-173 *C variant allele could significantly increase the risk of PCa (OR=2.96,95%CI: 1.92-4.57). Peo-ple with older age (age>70) or family history of cancer, who carried MIF-173 * C allele demonstra-ted a significantly increased risk in comparison with those carrying wild genotype of G/G(OR=3.66, 95%CI=2.02-6.62;OR=3.26, 95%CI=1.24-8.55). Conclusion These results suggested that polymorphisms of MIF-173 locus appear to influence the risk of PCa and may have synergistic effect with age and family history of cancer.

Objective To observe the solo-allied expression of Survivin, Smad4/dpc4 and APC gene, and study the relationship between the three genes and biological behavior of colorectal cancer. Methods The expressions of Survivin, Smad4/dpc4 and APC gene were detected by SP immunohistochem-istry among the cases from 40 eu-intestine ,80 large intestinal adenoma and 80 CRC. Results The positive rate of survivin protein in the eu-intestine, the large intestinal adenoma and CRC was 0,35.0% ,75.0% , respectively. The positive rate of Smad4/dpc4 protein was 100% , 95. 0% , 78. 8% , and the positive rate of APC protein was 100% ,80.0% ,45.0% , respectively. In the eu-intestine, APC + Smad4/dpc4 Z- expressed in 40 cases, with the incidence of 100%. In the large intestinal adenoma, APC + Smad4 expressed in 38 patients, with the incidence of 47. 5% , and the three genes expressed in 29 patients with the incidence of 23. 8%. In the CRC, two genes expressed in 57 patients, with the incidence of 71. 3% , and three genes expressed in 28 patients, with the incidence of 35.0%. Conclusion The detection of survivin was a new indicator in early diagnosis of CRC. It was significant in the diagnosis of CRC that energetic search for the positive rate level realm of survivin. The catastrophe or absence of Smad4/dpc4 gene not only induced the genesis of CRC but also encouraged its growth. Smad4/dpc4 was ant- carcinomatous gene intimately correlated to the CRC. Detection of APC gene had very important significance, it could be helpful to conduct the research of tumorous aetiology, nosogenesis and early diagnosis. The allied detection of Survivin, Smad4/dpc4, APC gene played a very important role in early diagnosing and healing the CRC.
