Objective To evaluate application of recombinant human luteinizing hormone (r-hLH)used in ovarian stimulation of assisted reproductive technique and impact on outcome of pregnancy. Methods From Apr. To Jul. 2009, 123 patients with low LH level ( < 1 U/L) at day 3 of menstruation and downregulation of pituitary function undergoing in vitro fertilization-embryo transfer (IVF-ET) in Reproductive Medical Center, Provincial Hospital Affiliated to Shandong University were enrolled in this study, whom were classified into 66 cases treated by r-hLH in r-hLH group and 57 cases without r-hLH treatment in non-r-hLH group. In the mean time, 145 patients with normal level of serum LH ( 1-2 U/L) not given by r-hLH treatment and undergoing IVF-ET were matched as control group. Total amount of gonadotropin, estradiol levels and LH levels on the administration of human chorionic gonadotropin ( hCG), number of oocytes retrieved, number of 2PN zygotes, rate of high quality embryos, the rates of implantation and clinical pregnancy were compared among these three groups. Results The level of serum LH on the day of hCG administration were ( 1.59 ± 0.77 ) U/L in r-hLH group, (0.54 ± 0.25 ) U/L in non-r-hLH group and (2.39 ± 1.01 ) U/L in control group, which reached tatistical difference between every two groups (P < 0.05). The rates of high quality embryo were 59.36％ in r-hLH group, 57.79％ in non-r-hLH group,which were significantly lower than 65.94％ in control group, respectively (P < 0. 05 ). The rates of 2PN were 67.62％ in r-hLH group and 68. 32％ in control group, which were significantly higher than 62. 84％ in non-r-hLH group, respectively ( P < 0.05 ). The rates of implantation of 29.77％ in r-hLH group were significantly higher than 18.26％ in non-r-hLH group ( P < 0.05 ). The total amount of gonadotropin,estradiol level on the day of hCG administration, the number of oocytes retrieved, and clinical pregnancy rate were not significantly different among those three groups ( P > 0.05 ). Conclusion The administration of recombinant human uteinizing hormone in patients who are profoundly suppressed after down-regulation with long protocol can get more quality embryos, the higher rates of 2PN and implantation.

Objective To investigate the impact of previous cystectomy for ovary benign cyst on ovarian reserve and pregnancy outcome in in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. Methods Totally 622 infertility patients were retrospectively investigated who underwent first IVF/ICSI-ET cycle in Reproductive Hospital Affiliated to Shandong University from January 2013 to June 2014. There were 153 cases who had been removed ovarian cyst by cystectomy surgeries recruited as study group, in which 44 cases of ovarian endometriosis cyst, 35 cases of benign ovarian teratomas, 67 cases of simple ovarian cyst and 7 cases of ovarian mucinous cystadenoma. In contrast, 469 infertility patients with tubal-factor infertility or male factor were included as control group. The age-matched women in the control group had no ovarian surgery previously. The indicators of ovarian reserve and pregnancy outcome were analyzed between two groups. The influence of different types of ovarian cysts on ovarian reserve and pregnancy outcome in IVF/ICSI-ET cycles were also studied, ovarian endometriosis cyst was studied as Group A, and Group B consisted of benign ovarian teratomas, simple ovarian cyst and mucinous cystadenoma. Results (1) The significantly lower serum antimullerian hormone (AMH) level (median: 1.92 versus 2.90 mg/L), antral follicle count (AFC; median: 12.0 versus 13.0), retrieved oocytes (12 ± 5 versus 13 ± 6) and the number of embryo cryopreserved (median:1.0 versus 3.0) were found in study group compared with control group (all P<0.05). There was no statistical difference between two group for the following parameters, such as basal FSH level, the total dosage of gonadotropin duration and the total dosage of gonadotropin (all P>0.05). A better clinical pregnancy rate was achieved in control group (61.6%, 241/391) than that in study group (61.4%, 81/132), but no significant difference was existed (P=0.96). (2) Compared to Group B, Group A had fewer AFC, lower serum AMH level, retrieved oocytes and the number of embryo cryopreserved (11±4 versus 13±5;1.65 versus 2.15 mg/L;9±4 versus 13±5;0 versus 2.0;all P<0.01). There was a lower clinical pregnancy rate in Group A than that in Group B [50.0% (19/38) versus 66.0%(62/94)], accompanying with higher abortion rate [3/19 versus 9.7%(6/62)], but no differences were observed (all P>0.05). Conclusions Ovarian reserve declines after the cystectomy for ovarian benign cysts and the cystectomy has a negative impact on IVF/ICSI-ET cycle, resulting in a decrease of the number of retrieved oocytes and the number of embryo cryopreserved, but do not influence clinical pregnancy outcome. Ovarian reserve is impaired more seriously by cystectomy for ovarian endometriosis cyst than other ovarian benign cyst.

A new method for manufacturing three-dimensional gel film-coated chips was described in this paper and its advantages were evaluated by its application. A patch of polyacrylamide gel (15mm x 15mm x 20 microm) was fixed on the glass surface with Bind-Silane treatment, then activated by glutaraldehyde. The aldehyde groups in gel provided reactive sites that allowed covalent immobilization of molecules containing amino groups. Oligonucleotides were mechanically spotted by GMS 417 Arrayer. After hybridization with Cy-3 labeled probes, fluorescence signals of perfect binding can be discriminated from mismatched ones. Compared with two-dimensional glass chip, the capacity of oligonucleotides immobilized on gel film-coated chip is over 100 times. And the gel film-coated chip have lower background and shorter hybridization time. Monoclonal antibodys of cytokine IL-4, IL-5, IL-6, IL-7, ANG, I-309 and VEGF were also immobilized on the gel film-coated chips to make protein microarrays. After incubation with serum of breast cancer patients or normal persons, the microarray reacted with biotin-labeled second antibodys of cytokines and Cy-3-labeled streptavidin sequentially. Results show IL-4, IL-5, I-309 and VEGF of patients have higher expression level than normal persons. This kind of protein microarrays can be potentially helpful to clinical diagnosis. Furthermore different oligonucleotides or proteins can be performed in parallel in a single reaction with minimal amount of binding reagents. Such gel film-coated chips can be used widely in the fabrication of oligonucleotides and proteins microarrays.

OBJECTIVETo investigate cyclooxygenase-2 (COX-2) expression and its relationship with mismatch repair (MMR) protein expression and microsatellite instability (MSI) in hereditary nonpolyposis colorectal cancer (HNPCC).

METHODSA total of 28 cases of colorectal adenoma and 14 cases of colorectal carcinoma were collected between July 2003 and July 2007 from 33 HNPCC families. Sporadic colorectal adenoma (n=32) and carcinoma patients (n=24) served as controls. With samples of tumor tissues and normal colonic mucosa collected from the patients, the protein expressions of COX-2 and MMR (hMLH1, hMSH2, and hMSH6) were examined with immunohistochemical assay. Frequency of MSI in five standard MSI loci BAT25, BAT26, D2S123, D5S346, and D17S250 were analyzed by means of polymerase chain reaction.

RESULTSThe rate of COX-2 high-expression was 53.6% (15/28) and 42.9% (6/14) in HNPCC adenoma and carcinoma; 62.5% (20/32) and 91.7% (22/24) in sporadic adenoma and carcinoma, respectively. That rate was lower in HNPCC carcinoma than in sporadic carcinoma (Pü0.05). MMR-deletion rate and percentage of high-frequency MSI (MSI-H) in HNPCC carcinoma were higher than those in sporadic colorectal carcinoma [both 71.4% (10/14) vs. 12.5% (3/24), both Pü0.01]. Among the 10 MMR-deficient HNPCC carcinoma patients, COX-2 low-expression was observed in 8 cases (80.0%), while COX-2 high-expression was observed in all of the 4 MMR-positive HNPCC carcinoma cases (Pü0.05). In comparison to MMR positive HNPCC carcinoma, HNPCC adenoma, and sporadic carcinoma, COX-2 expression was significantly lower in corresponding MMR-deficient cases (all Pü0.05). The rates of COX-2 low-expression in HNPCC adenoma, HNPCC carcinoma, and sporadic carcinoma with MSI-H were significantly higher than those in the cases with microsatellite stability (all Pü0.05).

CONCLUSIONCOX-2 is expressed at a low level in HNPCC carcinoma, different from the high COX-2 expression in sporadic carcinoma.

OBJECTIVETo observe whether adenosine Al receptor (Al R) mediated neuroprotection of Shenmai Injection (SI) on rat cerebral ischemia/reperfusion (I/R) injury.

METHODSThe focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO). Totally 60 successfully modeled rats was divided into 5 groups according to randomized block principle, i.e., the model group, the SI group, the SI + AlR antagonist (1,3-dipropyl-8-cyclopentylxanthine, DPCPX) group, the AlR antagonist control group, and the dimethyl sulfoxide (DMSO) control group, 12 in each group. Besides, a sham-operation group was set up (n =12). SI at 15 mL/kg was peritoneally injected to mice in the SI group immediately after cerebral I/R. Equal volume of normal saline was injected to mice in the model group and the sham-operation group. DPCPX at 1 mg/mL was peritoneally injected to mice in the Al R antagonist control group 30 min before peritoneal injecting SI. DPCPX at 1 mg/kg and DMSO at 1 mL/kg were peritoneally injected to mice in the AlR antagonist control group and the DMSO control group 30 min immediately before cerebral I/R. Rats' neurobehavioral scores were assessed after 24 h reperfusion. The volume of cerebral infarction and Bcl-2 protein expression of cerebral infarction penumbra were also detected. Results Compared with the sham-operation group, neurobehavioral scores, the volume of cerebral infarction, and Bcl-2 protein expression increased (all P <0. 05). Compared with the model group, neurobehavioral scores and the volume of cerebral infarction obviously decreased, but Bcl-2 protein expression increased in the SI group (all P <0. 05). Compared with the SI group, neurobehavioral scores increased, the volume of cerebral infarction was obviously enlarged, and Bcl-2 protein expression was obviously reduced in the A1R antagonist control group (all P <0. 05).

CONCLUSIONSSI's neurobehavioral scores could be partially reversed in the Al R antagonist control group, the volume of cerebral infarction and Bcl-2 protein expression improved. AlR might possibly meditate neuroprotection of SI on MACO mire

OBJECTIVETo understand the sero-prevalence of hepatitis E virus (HEV) infection among different populations and animals in Fujian province.

METHODSOne thousand one hundred and fifty-one serum samples were collected from 5 species of animals including swine, dog, cow, sheep and rat. A total of 2209 and 1722 serum samples from the general population and from the exposed population were collected. Anti-HEV IgG was detected by ELISA. The general population was composed of healthy blood donors and the individuals who had attended physical examination including farmers, handlers, veterinarians, cooks who worked with pigs or chickens while the poultry wholesale suppliers made up the exposure population.

RESULTSThe infection rates of HEV in animals were different between species (chi2 = 406.25, P < 0.01) with the highest seen in the pig group. With pigs being kept at home, the rates were between 70.00% and 94.12% but the rate was 39.77% for those families that keeping the pigs at farms. The infection rate of HEV was 23.3% in the general population and 33.3% in the exposed populations, respectively. A significantly higher infection rate for anti-HEV was found in the exposed population when comparing with general population. The positive rate of anti-HEV IgG was significantly higher in the exposed population that closely having had contact with chickens than those who had contact with pigs. The increasing trend of HEV infection rate with age had been found but there was no significant difference between males and females in the general population. In the exposed population, the infection rate in males was significantly higher than that in females.

CONCLUSIONThe infection ratse of HEV in pigs and in the exposure population were much higher, especially for those persons in close contact with chickens or pigs, suggesting that the sub-clinical infection for HEV might exist. These data further supported the hypothesis that HEV might have been an zoonotic disease.
