OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.

RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).

CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.

Objective To establish a mouse model of circulating tumor cells (CTCs) by applying mouse hepatoma Hapa 1-6 cells.Methods 108 healthy male C57BL/6 mice were randomly divided into 3 groups according to their body weights.Hepa 1-6 cell suspension was intravenously injected to each mouse in the three groups at a concentration of 1×106,5×106 and 1×107/mL,0.2 mL per mouse,respectively.Blood samples were collected from the mice on the 1st,5th,9th,13th,17th and 21st days after tumor cell injection.The number,ratio and relative inhibition rate of CTCs were calculated in 20,000 nucleated cells.The mortality of mice was recorded.②80 male C57BL/6 mice were averaged into 2 groups according to their body weight: control and sorafenib tosylate groups.0.2 mL of Hepa 1-6 single cell suspension was injected to each mouse through the caudal vein at a concentration of 5×106/mL.The mice were gavaged with sorafenib tosylate (50 mg/kg) for 21 days and blood samples were collected at the 3rd,8th,15th,and 21st days for CTC assessment.Results For the 1×106/mL group,the CTC inhibition rate was 25.1%,18.1%,8.9%,4.4%,2.9% and 0.3% on the 1st,5th,9th,13th,17th and 21st days,respectively,and all the mice were alive.For the 5×106/mL group,the CTC inhibition rate was 40.4%,35.4%,15.4%,9.0%,6.6% and 4.1% on the 1st,5th,9th,13th,17th and 21st days,respectively,and all the mice were alive.For the 1×107/mL group,the CTC inhibition rate was 39.1% and 33.5% on the 1st and 5th days,respectively.Some mice died immediately after intravenous injection and all mice died within 7 days.②The relative clearance of CTCs was-7.5%,4.6%,55.3% and-94.5% on the 3rd,8th,15th and 21st days of sorafenib tosylate administration.Compared with the control group,there were significant differences among the three groups (P<0.05 or P<0.01).Conclusions A mouse model of circulating hepatoma cells has been established by intravenous injection of 0.2 mL of 5×106/mL mouse Hepa 1-6 cell suspension.This mouse model can be used for screening and evaluation of drugs for circulating tumor cell inhibition.

Objective To study the clinical data of patients with locally advanced cervical cancer(LACC)treated with preoperative radiotherapy plus chemotherapy combined with surgery. Methods Seventy patients with LACC(stage ⅠB2,ⅡA2 andⅡB)who were treated in our hospital from January 2012 to December 2016 were selected in this study.All the cases were randomly divided into two groups.The observation group(n=35)was treated with three-dimensional intracavitary brachytherapy plus chemotherapy combined with surgery, while the control group (n=35) was treated with radical radiotherapy.Patients of the two groups were followed up after the treatment.The recent and long term complications were recorded and observed in the two groups.Meanwhile,the survival curves were drawn by Kaplan-Meier,and the difference of total survival rate was compared with the Log-rank method between the two groups. Results The incidence of rectal reaction was less in the observation group than that in the control group(14.3% vs.37.1%,χ 2=4.786,P<0.05).There were no significant differences in bone marrow suppression,gastrointestinal reaction and bladder reaction between the two groups (P>0.05). The incidence rates of radioactive bladder injury (8.6% vs. 31.4%) and radionuclide injury (11.4% vs. 34.2%) were less in the observation group than those in the control group(χ2=5.714 and 5.185 respectively,P<0.05).The survival analysis showed that there was no significant difference in the total survival rate between the two groups of stageⅠB2+ⅡA2 and stageⅡB patients(Log rank χ2=0.081 and 0.376,P>0.05).Conclusion For patients with locally advanced cervical cancer, preoperative radiotherapy plus chemotherapy combined with surgery can reduce the incidence of related complications, meanwhile, there is no significant difference in the total survival rate and the mean survival time after the treatment of the two methods.

OBJECTIVEThe present study was designed to explore the practical application of the rapid etiological diagnosis by detecting specific IgM antibody against common respiratory viruses in children with acute lower respiratory infections (ALRI).

METHODClinical specimens including nasopharyngeal aspirates and serum of acute phase from hospitalized children were collected from 207 infants and children with acute lower respiratory infections from March 2009 to September 2010. Seven common respiratory virus antigens were identified from the collected nasopharyngeal aspirates by direct immunofluorescence assay (DFA). ELISA was used to detect specific IgM antibody against RSV, ADV, IFVA, IFVB and PIV, while indirect immunofluorescence assay (IFA) was used to detect specific IgM antibody against RSV, ADV, IFVA, IFVB, PIV1, PIV2 and PIV3 in collected acute phase serum.

RESULTThe overall positive rates to detect viral antigen by using DFA, ELISA and IFA was 67.6%, 57.5% and 39.6%, respectively. The consistent rate of ELISA and IFA versus accepted DFA were 21.7% and 31.4%, respectively. The average days from onset of the symptoms to blood sample collection for those with the consistent results by ELISA and DFA were 12.0 d for ADV, 9.6 d for PIV2, 9.5 d for IFV, and 5.3 d for RSV, respectively, and by IFA and DFA were 15.0 d for PIV3, 9.2 d for ADV, and 7.4 d for RSV, respectively. Among all age groups, the consistent rate of serum viral IgM and antigen detections was highest in children younger than 3 years old.

CONCLUSIONAlthough there were differences between serum IgM antibody and viral antigen detections, specific IgM antibody detection was of value in early and rapid etiological diagnosis of pediatric ALRI, especially for young children. It could provide serologic evidence of respiratory virus infection. The diagnostic rate of pathogen could be improved if it was used in combination with viral antigen diagnostic methods.

OBJECTIVETo explore the association between Alzheimer's disease (AD) and nitric oxide synthase (NOS) III in Chinese Han population.

METHODSSeventy-five AD and 68 normal controls were genotyped for NOS III G894T polymorphism. Genotyping was carried out by PCR-RFLP methods.

RESULTSThere were two genotypes of NOS III, GG and GT, in either AD patients or normal controls. The frequencies of these two genotypes were 78.7% and 21.3% in AD patients and 82.4% and 17.6% in normal controls, respectively. No association was found between AD and NOS III genotype (P > 0.05). There were two alleles, G and T, in AD patients and normal controls. The frequencies of these two alleles were 89.3% and 10.7% in AD patients and 91.2% and 8.8% in normal controls, respectively, indicating that there was no association between AD and NOS III allels (P > 0.05).

CONCLUSIONSThere was no association between AD and NOS III G894T polymorphism in Chinese Han population.

OBJECTIVETo observe the therapeutic effect of Zhenggan Recipe (ZGR) in treating liver cirrhosis with abnormal Alpha-fetoprotein (AFP), and to explore its mechanism.

METHODSSixty-four patients of liver cirrhosis with abnormal AFP were randomly divided into the treated group and the control group. All the patients received conventional combined Western medicinal treatment. Besides, additional ZGR was given to the patients in the treated group, one dose every day for orally taken in two times, 6 months as a therapeutic course. Changes in liver function (ALT, GGT, TBIL and ALB), AFP, T-lymphocyte subsets (CD4, CD4/CD8) and iconological examination were observed in the two groups before and after treatment to compared the efficacy.

RESULTSZGR could effectively lower the AFP level (P < 0.01), and improve the levels of CD4 and CD4/CD8 (P < 0.01 or P < 0.05).

CONCLUSIONZGR can effectively lower the level of AFP, its mechanism might be related to the improving of cellular immune function of the patients.
