Objective:To define the expression levels of MDM2 gene in nasopharyngeal carcinoma (NPC)and its relationship with p53 protein expression and EB virus latent infection. Method :MDM2 gene expression atmRNA and protein levels,p53 protein and EB virus DNA were detected by nonradioactive in situ hybridization(ISH) ,immunohistochemistry(IHC) and polymerase chain reaction (PCR) separately in 46 cases of NPC tissuesand 12 cases of chronic inflammation of nasopharyngeal epithelium (CINE). Result: Fourteen cases of NPCshowed MDM2 mRNA and protein overexpression, 38 cases were p53 protein positive,and 43 cases were EBV-DNA positive. Neither MDM2 nor p53 protein was expressed in any case of CINE. MDM2 expression was signifi-cantly related to p53 protein expression ( P <0. 05), but not to EB virus latent infection in NPC. Conclusion:MDM2 gene may play an important role in the pathogenesis of NPC through interacting with p53 protein.

Objective To study the relationship between a CAG repeat polymorphism of the androgen receptor (AR) gene and postmenopausal osteoporosis (PMO). Methods Genotypes for the AR polymorphisrn were determined by gene scan and DNA sequence methods in a case-control study,including 78 cases of PMO at femoral neck and 73 cases as controls, and 108 cases of PMO at lumbar spine (L2-4) and 60 cases as controls. Bone mineral density for the proximal femur and L2-4 was measured by NORLAND XR-46 dual-energy X-ray absorptiometry. The relationship between the CAG repeat polymorphism and PMO was investigated. Results Eleven different allelic variants,containing 18, 20, 21, 23, 24, 25, 26, 27, 28, 29, and 30 CAG repeats were detected, 16 genotypes were present in the subjects. There were no significant differences in the genotype and allele distributions of (CAG) n polymorphism between PMO group (SS : 25.6 %, SL : 39.7%, LL : 34.6 % ;S:45.5%,L:54.5%) and control group (SS: 23.3%,SL=45.2% ,LL:31.5%;S:45.9%,L:54.1%) at the femoral neck site (all P>0.05). The risk of PMO at femoral neck in females with the genotypes of SL (0R:0.798,95%CI:0.335~1.797), the LL (0R:0.998,95%CI:0.425~2.341), and the combined SL and LL (OR:0.880, 95% CI: 0.419~1.852) were not significantly increased in comparison with those of females with the SS genotype (all P>0.05). There were no significant differences in the genotype and allele distributions of (CAG)n polymorphism between PMO group(SS: 18.5%, SL: 49.1%, LL: 32.4%;S:43.1%, L: 56.9%) and control group (SS: 21.7%, SL:45.0% ,LL:33.3% ;S:44.2% ,L:55.8%) at the L2-4 site (P>0. 05). The risk of PMO at L2-4 in females with the genotypes of SL (OR:1. 276,95%CI:0. 552~2. 950), the LL (OR:1. 137,95%CI:0.468~2.766), and the combined SL and LL (OR: 1. 217,95% CI: 0. 556 ~2. 663 ) were not significantly increased in comparison with those of females with the SS genotype (all P>0.05). After adjustments for age, postmenopausal period, menopausal age, and body mass index, the logistic regression analyses revealed the (CAG)n polymorphism was not significantly associated with PMO at the femoral neck and L2-4 site (all P>0.05). Conclusions The CAG repeat polymorphism in the AR gene may not be associated with PMO at the femoral neck and L2-4 site.

Objective To compare the efficacy between bronchial artery infusion (BAI) chemotherapy plus radiation therapy and systemic chemotherapy plus radiation for locally advanced non-small cell lung cancer (NSCLC). Methods One hundred and twenty-one patients with stage III NSCLC were randomized into treatment group(58 cases) and control group (63 cases). In the treatment group, all patients were administered with BAI for 2-3 sessions, followed by irradiation 4-7 days after BAI. In the control group, altogether 4-6 cycles of standard systemic chemotherapy were given. Radiation was delivered alternately between the cycles of chemotherapy. Results The short-term, long-term survival, median response duration and median survival time were similar between the two groups, except patients with stage Ⅲb who had a higher distant metastasis rate in the treatment group. The major side effects of chemotherapy and radiotherapy were hematological, gastrointestinal toxicities, pneumonitis, mediastinitis, and esophagitis, respectively. The side effects were milder, better tolerated and did not influence the regimen schedule in the treatment group, as compared with the control group. Seven patients withdrew from the control group, and in 28 patients, the scheduled chemotherapy and radiation was delayed or canceled. Conclusions Bronchial artery infusion plus radiation is more advantageous over systemic chemotherapy plus radiation in less toxicities, better compliance, shorter treatment courses and more cost-effectiveness.

OBJECTIVETo evaluate the relationship between levels of soluble Fas (sFas) and soluble Fas ligand (sFasL) in serum and peritoneal fluid of endometriosis-associated infertility.
METHODSThe soluble Fas ligand and soluble Fas levels in serum and peritoneal fluid of 20 infertile patients with endometriosis were assessed with enzyme-linked immunosorbent assay, and were compared with 14 infertile patients due to chronic pelvic infectious disease and 16 fertile controls.
RESULTSThe sFasL levels were significantly higher in infertile patients with endometriosis (175.09 +/- 80.55 pg/mL in serum and 284.50 +/- 152.38 pg/mL in peritoneal fluid) than those of infertile controls (88.47 +/- 43.55 pg/mL in serum and 17.30 +/- 9.62 pg/mL in peritoneal fluid) and fertile controls (16.13 +/- 11.75 pg/mL in serum and 8.84 +/- 2.31 pg/mL in peritoneal fluid). In contrast, as for the sFas levels, infertile patients with endometriosis (828.60 +/- 429.65 pg/mL in serum and 349.61 +/- 288.89 pg/mL in peritoneal fluid) did not show any significant difference compared with those in infertile patients resulting from pelvic infectious disease (868.75 +/- 570.48 pg/mL in serum and 181.76 +/- 157.78 pg/mL in peritoneal fluid) and fertile control (822.26 +/- 129.12 pg/mL in serum and 318.42 +/- 145.16 pg/mL in peritoneal fluid).
CONCLUSIONSBased upon these results, high level of sFasL in serum and peritoneal fluid and thus apoptosis mediated by it may be implicated in the mechanism involved in endometriosis-related infertility.

OBJECTIVE:
To explore the pathogenesis and genetic characteristics of a fetus with a der(X)t(X;Y)(p22.3;q11.2) karyotype.
METHODS:
G-banding karyotyping analysis, BoBs (BACs-on-Beads) assay, and single nucleotide polymorphism array (SNP-array) were used to delineate the structural chromosomal aberration of the fetus. The parents of the fetus were also subjected to karyotyping analysis.
RESULTS:
The fetus and its mother were both found to have a karyotype of 46,X,add(X)(p22), while the father was normal. BoBs assay indicated that there was a lack of Xp22 but a gain of Yq11 signal. SNP-array confirmed that the fetus and its mother both had a 7.13 Mb deletion at Xp22.33p22.31 (608 021-7 736 547) and gain of a 12.52 Mb fragment at Yq11.221q11.23 (16 271 151-28 788 643).
CONCLUSION
The fetus was determined to have a karyotype of 46,X,der(X)t(X;Y)(p22.3;q11.2)mat. The combined use of various methods has facilitated delineation of the fetal chromosomal aberration and prediction of the risk prediction for subsequent pregnancy.

OBJECTIVETo analyze the results of nine-round environmental specimen surveillance programs in five live poultry markets pre-, during and post the 'closing days' and to evaluate the effects of 'closing days' on live poultry markets regarding the control against avian influenza pollution.
METHODSIn January 2014, control measures including culling poultry, completely cleaning and disinfecting and a 'three-day-closing' measure were conducted in five live poultry markets which were found positive for H7N9 nucleic acid in the 1(st) round environmental specimen surveillance program. Second surveillance program was conducted after a thorough disinfection campaign was launched. Several times surveillance were conducted in one week, after the markets were reopened. RT-PCR was used to test the nucleic acid of HA, H5, H7 and H9 viruses.
RESULTS654 specimens from the environment were collected and tested. During the first round surveillance program, positive rates for influenza A and H5/H7/H9 nucleic acid of poultry stalls appeared to be 94.44% and 61.11% respectively. The positive rates of poultry stalls reduced to 0 after the disinfection campaign but increased again after the markets reopened. The positive rate for influenza A of poultry stalls slightly increased from 50.00% in the third surveillance to 72.22% in the ninth surveillance (P > 0.05). The positive rate for H5/H7/H9 of poultry stalls showed a significantly increasing trend, from 0 in the third surveillance to 44.44% in the ninth surveillance (P < 0.01). The positive rates for influenza A and H5/H7/H9 nucleic acid of specimens were 28.89% and 17.78% respectively. The positive rate of specimens reduced to 0 after disinfection while increased again after reopening of the markets. The positive rate for influenza A of specimens slightly increased from 19.67% in the third surveillance to 27.54% in the ninth surveillance programs (P > 0.05). The positive rate for H5/H7/H9 of specimen showed a significant increasing trend, from 0 in the third surveillance to 8.70% in the ninth-round surveillance programs (P < 0.01). The positive rate for influenza A was the highest for slaughter- related specimens of 22.4% (35/156). The positive rates for influenza A from sewage and drinking water being collected on the later stage after the markets reopened (25.9%, 12.4%)were higher than those on the early stage (8.3%, 8.6%) (P > 0.05). The positive rate for influenza A of poultry stalls with overnight poultry storage (91.7%) was significant higher than that of poultry stalls without the overnight storage (33.3%). The positive rate for influenza A of poultry stalls in which simultaneously selling different kinds of poultry (85.7%) was significant higher than that of poultry stalls in which selling only one kind of poultry at one time (25.0%) (P < 0.05).
CONCLUSIONSlaughter in live poultry markets posed a large risk of pollution diffusion. Sewage and drinking water showed an accumulation effect for avian influenza virus. Overnight poultry storage and selling different kinds of poultry at one time at the poultry stalls seemed the risk factors for avian influenza virus transmission. Complete cleaning, disinfecting and several 'closing days' for live poultry markets seemed effective in eliminating avian influenza virus. Once the markets were reopened, they seemed to be soon polluted again.
