Abstract
BACKGROUND Routine HIV testing accompanied with pre-exposure prophylaxis (PrEP) requires innovative support in a real-world setting. OBJECTIVE This study aimed to determine the usage of HIV self-testing (HIVST) kits and their secondary distribution to partners among men who have sex with men (MSM) in China, who use PrEP, in an observational study between 2018 and 2019. METHODS In 4 major cities in China, we prospectively followed-up MSM from the China Real-world oral PrEP demonstration study, which provides daily or on-demand PrEP for 12 months, to assess the usage and secondary distribution of HIVST on quarterly follow-ups. Half of the PrEP users were randomized to receive 2 HIVSTs per month in addition to quarterly facility-based HIV testing. We evaluated the feasibility of providing HIVST to PrEP users. RESULTS We recruited 939 MSM and randomized 471 to receive HIVST, among whom 235 (49.9%) were daily and 236 (50.1%) were on-demand PrEP users. At baseline, the median age was 29 years, 390 (82.0%) men had at least college-level education, and 119 (25.3%) had never undergone facility-based HIV testing before. Three months after PrEP initiation, 341 (74.5%) men had used the HIVST provided to them and found it very easy to use. Among them, 180 of 341 (52.8%) men had distributed the HIVST kits it to other MSM, and 132 (51.6%) among the 256 men who returned HIVST results reported that used it with their sexual partners at the onset of intercourse. Participants on daily PrEP were more likely to use HIVST (adjusted hazard ratio=1.3, 95% CI 1.0-1.6) and distribute HIVST kits (adjusted hazard ratio=1.3, 95% CI 1.1-1.7) than those using on-demand PrEP. CONCLUSIONS MSM who used PrEP had a high rate of usage and secondary distribution of HIVST kits, especially among those on daily PrEP, which suggested high feasibility and necessity for HIVST after PrEP initiation. Assuming that fourth-generation HIVST kits are available, HIVST may be able to replace facility-based HIV testing to a certain extent.

Abstract
Background Over half of men who have sex with men (MSM) use geosocial networking (GSN) apps to encounter sex partners. GSN apps’ users have become a unique large subpopulation among MSM for interventions concerning HIV prevention and control. Pre-exposure prophylaxis (PrEP) is a promising measure for HIV prevention, especially for MSM, but its effectiveness largely depends on medication adherence. However, little is known about PrEP adherence among GSN apps’ users, which is critical to addressing the overall optimization of PrEP compliance outside of clinical trials in the context of large-scale implementation. Objective The objective of this study is to understand the correlation between GSN apps’ use and medication adherence among MSM receiving PrEP, with the aim to increase their awareness about PrEP use in order to increase adherence. Methods This study based on the China Real-world Oral intake of PrEP (CROPrEP) project, a multicenter, real-world study of Chinese MSM on daily and event-driven PrEP. Eligible participants completed a detailed computer-assisted self-interview on sociodemographic, GSN apps’ use, and sexual behavior. Then participants were followed up for 12 months and assessed for various characteristics (eg, PrEP delivery, adherence assessment, PrEP coverage of sexual activities, and regimens switch). A generalized estimation equation was used to analyze the predictors of medication adherence and regimen conversion among GSN apps’ users and nonusers. Results At baseline, 756 of the 1023 eligible participants (73.90%) reported primarily using GSN apps to seek sexual partners, and GSN apps’ users are more likely to have high-risk behaviors such as multiple sex partners and condomless anal intercourse than other nonusers (all P<.05). During follow-up, GSN apps’ users had a significantly low level of pill-counting adherence than nonusers (adjusted odds ratio [aOR] 0.8, 95% CI 0.6-1.0, P=.038). In the event-driven group, GSN apps’ users had marginally lower levels of self-reported adherence (aOR 0.7, 95% CI 0.4-1.0, P=.060) and lower PrEP coverage of sexual practices (aOR 0.6, 95% CI 0.4-1.0, P=.038). Additionally, GSN apps’ users seemed more likely to switch from event-driven to daily regimen (aOR 1.8, 95% CI 0.9-3.3, P=.084). Conclusions GSN apps’ users are highly prevalent among MSM, despite their higher sexual risk and lower adherence levels, suggesting that eHealth needs to be introduced to the GSN platform to promote PrEP adherence.

Abstract
Background Nitrite inhalant use is very common among men who have sex with men (MSM) in China. However, there is lack of national representative data on use among Chinese MSM, and the mechanism of how nitrite inhalant use impacts HIV infection in MSM is unclear. This meta-analysis aims to understand the characteristics of Chinese MSM nitrite inhalant users and to determine the associations between nitrite inhalant use and sexual behaviors, the prevalence of HIV, and the prevalence of syphilis. Methods We searched PubMed, Web of Science, Chinese National Knowledge Infrastructure, Chinese Wanfang Data, and VIP Chinese Journal Database for relevant literature published from January 1985 to December 2017. Results Fifteen eligible studies, with a total of 18,981 Chinese MSM participants, were included. Compared with nitrite inhalant nonusers, users were more likely to be younger, have a higher level of education, and seek sexual partners using the Internet. Nitrite inhalant users were more likely to engage in high-risk sexual behaviors, including condomless anal intercourse (odds ratio [OR] = 1.33), group sex (OR = 2.26), and commercial intercourse (OR = 1.50). Nitrite inhalants users had a higher prevalence of HIV (OR = 1.83), higher prevalence of syphilis (OR = 1.38) and had higher lifetime HIV testing rates (OR = 1.33) compared with nonusers (each p < 0.05). Conclusions Nitrite inhalant users have higher HIV and syphilis prevalence by increasing levels of high-risk sexual behaviors. China should expand HIV testing, treatment as prevention (TasP), and Pre-exposure prophylaxis (PrEP) among MSM, especially among nitrite inhalants using MSM, to reduce their risk of HIV infection and transmission.

Abstract
Background Pre-exposure prophylaxis (PrEP) is an effective biomedical strategy to prevent transmission of HIV infection, although medication adherence remains a challenge. We present the protocol for a multicentre randomised controlled trial to measure the effectiveness of a real-time monitoring and just-in-time intervention on medication adherence among PrEP users in China. Methods Study participants will include 1000 men who have sex with men (MSM) from four cites in China (Shenyang, Beijing, Chongqing and Shenzhen) attending a tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) PrEP project as part of a real-world, prospective multicentre cohort study (CROPrEP). Participants will be randomised into the intervention and control arms in a 1:1 ratio. Participants in the intervention arm will be provided with remote real-time monitoring equipment that triggers twice just-in-time SMS (Short Messaging Service) medication reminders to PrEP users every half an hour when a scheduled dosage is missed, and followed with just-in-time SMS medication reminders to clinicians half an hour when there is no supplement after the second just-in-time SMS reminder to PrEP users. Clinicians will initiate individualised telephone intervention as soon as possible upon receipt of the just-in-time SMS missed dose alert. Those in the control arm will only receive generic weekly SMS reminders. The study will last 6 months. Participants will be seen at follow-up visits at three and 6 months. Trial outcomes to be measured include self-reported adherence assessed via questionnaire and pill counts, as well as drug concentration test results. Discussion Medication adherence is critical to achieve optimal benefits from PrEP. This study will be the first individualised behaviour intervention using real-time technology to increase adherence among MSM PrEP users globally. If found effective, a real-time monitoring and just-in-time intervention system may be utilized for improving adherence and thus effectiveness of global PrEP application. Trial registration This study registered at ClinicalTrials.gov (ChiCTR1900025604) on September 2, 2019.

Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) reduces the risk of HIV infection among men who have sex with men by up to 99%. However, in real-world settings, PrEP users may exhibit risk compensation after uptake of PrEP, including more condomless anal intercourse (CAI) and increased sexually transmitted infection (STI) acquisition. HIV self-testing (HIVST) decreases CAI among men who have sex with men (MSM) by providing awareness of the HIV status of oneself and one's sexual partners. Here, we describe the rationale and design of a randomised waitlist-controlled trial to examine the impact of HIVST on risk compensation among PrEP users. METHODS AND ANALYSIS The study is a two-arm randomised waitlist-controlled trial with 1000 HIV-negative MSM in four major cities in China who will be taking oral PrEP (involving tenofovir disoproxil fumarate/emtricitabine) either daily (n=500) or in an event-driven regimen (n=500). The participants will be randomised (1:1) to either the immediate HIVST intervention arm (HIVST plus standard facility-based counselling and testing from 0 to 12 months) or the waitlist arm (standard facility-based counselling and testing from 0 to 6 months, then crossover to receive the HIVST intervention in months 7-12). Participants will provide blood samples to assess the incidence of syphilis and herpes simplex virus type 2 (HSV-2) during a follow-up. The primary outcomes will be the occurrence of CAI, number of sexual partners and incidence of syphilis and HSV-2 during a follow-up. The secondary outcomes will be the HIV and STI testing frequency and STI treatment adherence during a follow-up. The planned start and end dates for the study is 26 December 2018 and 31 December 2020. ETHICS AND DISSEMINATION The Medical Science Research Ethics Committee of The First Affiliated Hospital of China Medical University has approved the study (IRB(2018)273).

Abstract
Objective: To compare the efficacy and safety of mycophenolate mofetil versus cyclosporine A in treating children with primary refractory nephrotic syndrome. Methods: Conducted a prospective randomized controlled clinical trial in 62 pediatric patients (including 44 boys and 18 girls), age ranged from 2.1 to 17.0 years; 32 cases presented with frequently relapsing nephrotic syndrome (FRNS) and 30 cases presented with steroid-resistant nephrotic syndrome (SRNS), who were admitted to department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from October 2013 to October 2015. The patients received either mycophenolate mofetil (20-30)mg/(kg·d) or cyclosporine A (3-5)mg/(kg·d) randomly, on the basis of prednisone treatment. Follow-up interview was conducted regularly for at least one year. Efficacy rate, relapse rate, time required for induction of remission, relapse-free period and prednisone dosage were compared between the two groups. Results: (1) Renal histologic examination, which was available for 17 patients, revealed minimal change disease in 8 patients, mesangial proliferative glomerulonephritis (MsPGN) in five, membranous nephropathy in two, and focal segmental glomerulosclerosis (FSGS) in two. (2) Comparison of mycophenolate mofetil versus cyclosporine A in children with FRNS: There were 14 patients with FRNS in mycophenolate mofetil group and 18 patients with FRNS in cyclosporine A group respectively. The relapse rate (episodes/year) in cyclosporine A group was lower than that of mycophenolate mofetil group (1.0 (0.0, 1.0) vs. 1.0 (1.0, 3.0), Z=-2.405, P=0.016). The relapse-free period (months) in cyclosporine A group was longer than that of mycophenolate mofetil group (10.0 (5.7, 12.1) vs. 5.0 (1.0, 11.0), Z=-1.984, P=0.047). No significant difference in dosage of prednisone was found between cyclosporine A and mycophenolate mofetil groups when followed up for 1 year. (3) Comparison of mycophenolate mofetil versus cyclosporine A in children with SRNS: The efficacy rate was 6/14 in mycophenolate mofetil group and 13/16 in cyclosporine A group. The complete remission rate was 4/14 in mycophenolate mofetil group and 12/16 in cyclosporine A group (P<0.05). The time (months) required for induction of remission in cyclosporine A group was significantly shorter than that of mycophenolate mofetil group (1.0 (1.0, 2.0) vs. 3.0 (2.5, 4.0), Z=-2.529, P=0.011). No significant differences were found between the two groups with respect to relapse-free period and relapse rate. (4) Except that one patient developed hypertensive encephalopathy in cyclosporine A group, no other serious adverse events were recorded. There were no significant differences between two groups with respect to adverse events. Conclusion: Our results indicated that both mycophenolate mofetil and cyclosporine A were effective in the treatment of children with refractory nephrotic syndrome. Cyclosporine A was superior to mycophenolate mofetil in preventing relapses in patients with FRNS and inducing complete remission in patients with SRNS. Although most patients were able to tolerate mycophenolate mofetil and cyclosporine A, but the toxicity and safety of cyclosporine A should be monitored closely.

Abstract
OBJECTIVE To retrospectively analyze the nutritional status and growth and development situation of the children with chronic kidney disease stage 3 to 5 when they were diagnosed at the first visit. METHOD After searching for the data of all the hospitalized cases during January 2007 to September 2015 in the Department of Nephrology of Children's Hospital Affiliated to the Capital Institute of Pediatrics from the medical record system, data of 37 cases with complete clinical data were collected; all these cases were diagnosed as chronic kidney disease stage 3 to 5 according to the diagnostic criteria.We recorded these children's age, height, weight, body mass index, albumin, blood lipids and acidosis situation when they were first diagnosed, and then, analyzed and summarized their nutritional status and growth and development situation. RESULT In these 37 cases, 24 cases were boys and 13 cases were girls; 23 cases (62%) were shorter than the third percentile of age-sex-specific height; 18 cases (49%) exhibited lower weight than the third percentile of age-sex-specific weight; 5 cases (13.5%) showed lower BMI than the third percentile of height-age BMI, and 5 cases (13.5%) had obesity. The level of albumin was (37.0±8.7) g/L, and no statistically significant difference was observed within each stage. In all of these cases, 10 cases were hypoalbuminemia (27%), and the difference of its frequency between stage 3-4 and stage 5 was not statistically significant. Triglyceride was (2.2±1.1) mmol/L. The mean level was higher than the normal range, but with no statistically significant difference within each stage; 21 cases (62%) were diagnosed as hypertriglyceridemia, which were more frequent compared with the occurrence of the hypercholesterolemia (32%), the high low density lipoprotein (26%) and the low high density lipoprotein(12%). And the occurrence of decompensated metabolic acidosis in stage 5 (69%) was significantly higher than that in stage 3-4 (38%) (P=0.036 6, <0.05). CONCLUSION Growth retardation is highly prevalent among the children with chronic kidney disease stage 3 to 5. It would become more frequent and more serious as the stage worsening. Both underweight and obesity could be observed in this kind of children. Low serum albumin level is not a sensitive indicator of malnutrition in these children. The mean value of triglyceride in the children with chronic kidney disease was higher than the normal range. And hypertriglyceridemia is the most common abnormal lipid metabolism in our study.

Abstract
Euroleon coreanus (Okamoto) is widely distributed in China, and the larval stage can be treated as traditional Chinese medicine. However, the host-bacterium relationship remains unexplored, as there is a lack of knowledge on the microbial community of ant lions. Hence, in the current study, we explored the microbial community of the larval ant lion E. coreanus using Illumina MiSeq sequencing. Results indicated that a total of 10 phyla, 126 genera, and 145 species were characterized from the second instars of E. coreanus, and most of the microbes were classified in the phylum Proteobacteria. Cronobacter muytjensii was the most abundant species characterized in the whole body and gut of E. coreanus, and the unclassified species in the genera Brevundimonas and Lactobacillus were relatively more abundant in the head and carcass. In addition, no Wolbachia-like bacteria were detected, whereas bacteria like Francisella tularensis subsp. Holarctica OSU18 and unclassified Rickettsiella were first identified in ant lion E. coreanus.

Abstract
INTRODUCTION Stillbirth remains a devastating health issue with 26,000 stillbirths occurring annually in the United States. Formalin-fixed, paraffin-embedded (FFPE) umbilical cord samples are available for many stillbirths. Our aim was to validate the use of these samples in identifying genetic variations in stillbirth through microarray analysis. METHODS This is a retrospective case-control study from a single institution of stillbirths ≥ 23 weeks gestational age and control liveborn infants. Fetal genomic DNA was extracted from FFPE umbilical cord samples of stillborn and control placentas, and genotyping was performed using the Illumina HumanOmniExpresss-12v1 Beadchip. Array results were verified with qPCR. RESULTS 31 case-specific CNVs (17 deletions and 14 amplifications) with an average size of 294 kb for amplifications and 74 kb for deletions were identified among 94 FFPE samples (86 cases; 8 controls). In total 38 (44%) of the stillbirth samples had a CNV detected. Validation of a subset of microarray findings with qPCR confirmed deletions on 1p (2 cases), 11q (4 cases) and amplifications on 18 (1 case). Placental underperfusion changes were seen in stillborns with deletions on 1p, a region containing complement regulatory genes which have been shown to play a role in preeclampsia. DISCUSSION This study validated the use of archived FFPE umbilical cord samples for genome-wide copy number profiling in stillbirths, and demonstrates specific CNV deletions and amplifications. Microarray analysis in an expanded cohort of stillbirth FFPE samples has the potential to identify biomarkers involved in stillbirth pathogenesis.

Abstract
Dental caries remains one of the most common infectious diseases of humankind, which develops slowly throughout life, affecting children, adolescents, and adults. A vaccine against caries is urgently needed. We previously developed recombinant flagellin as a mucosal adjuvant for anti-Streptococcus mutans vaccines by nasal immunization. Furthermore, we demonstrated a fusion protein strategy that combined flagellin and the target surface adhesion protein (PAc) in a single construct. This construct enhanced specific IgA responses in oral fluids and provided improved prophylactic protection against caries. In the present study, we observed prolonged progression of dental caries in rats after S. mutans Ingbritt challenge. In addition, we observed a therapeutic effect of the flagellin-PAc fusion protein (KF-rPAc) against dental caries as a mucosal vaccine with a new immunization protocol. The present study demonstrated that KF-rPAc by nasal immunization can promote PAc-specific systemic and mucosal antibody responses and inhibit dental caries progression efficiently after the implant of S. mutans into the oral cavity of the rats. The rats immunized with KF-rPAc exhibited 53.9% caries reduction compared with the sham-immunized rats. Our data support the concept of administration of KF-rPAc to humans after infection and even caries that has begun to alleviate caries progression. In conclusion, our study demonstrated that KF-rPAc could be used as an anticaries therapeutic mucosal vaccine.

Abstract
BACKGROUND Sleep fragmentation during late gestation (LG-SF) is one of the major perturbations associated with sleep apnea and other sleep disorders during pregnancy. We have previously shown that LG-SF induces metabolic dysfunction in offspring mice during adulthood. OBJECTIVES To investigate the effects of late LG-SF on metabolic homeostasis in offspring and to determine the effects of LG-SF on the epigenome of visceral white adipose tissue (VWAT) in the offspring. METHODS Time-pregnant mice were exposed to LG-SF or sleep control during LG (LG-SC) conditions during the last 6 days of gestation. At 24 weeks of age, lipid profiles and metabolic parameters were assessed in the offspring. We performed large-scale DNA methylation analyses using methylated DNA immunoprecipitation (MeDIP) coupled with microarrays (MeDIP-chip) in VWAT of 24-week-old LG-SF and LG-SC offspring (n=8 mice per group). Univariate multiple-testing adjusted statistical analyses were applied to identify differentially methylated regions (DMRs) between the groups. DMRs were mapped to their corresponding genes, and tested for potential overlaps with biological pathways and gene networks. RESULTS We detected significant increases in body weight (31.7 vs 28.8 g; P=0.001), visceral (642.1 vs 497.0 mg; P=0.002) and subcutaneous (293.1 vs 250.1 mg; P=0.001) fat mass, plasma cholesterol (110.6 vs 87.6 mg dl(-1); P=0.001), triglycerides (87.3 vs 84.1 mg dl(-1); P=0.003) and homeostatic model assessment-insulin resistance values (8.1 vs 6.1; P=0.007) in the LG-SF group. MeDIP analyses revealed that 2148 DMRs (LG-SF vs LG-SC; P<0.0001, model-based analysis of tilling-arrays algorithm). A large proportion of the DMR-associated genes have reported functions that are altered in obesity and metabolic syndrome, such as Cartpt, Akt2, Apoe, Insr1 and so on. Overrepresented pathways and gene networks were related to metabolic regulation and inflammatory response. CONCLUSIONS Our findings show a major role for epigenomic regulation of pathways associated with the metabolic processes and inflammatory responses in VWAT. LG-SF-induced epigenetic alterations may underlie increases in the susceptibility to obesity and metabolic syndrome in the offspring.

Abstract
Sepsis is characterized as an uncontrolled inflammatory response. Spite et al. (Nature 461(7268):1287-1291, 2009) had demonstrated that resolvin D2, which is derived from docosahexaenoic acid (DHA), improves survival in cecal ligation and puncture (CLP)-initiated sepsis and enhances bacterial clearance without immune suppression. Resolvin D1, which is also derived from DHA and homologous with resolvin D2, is an endogenous anti-inflammatory and proresolving lipid molecule. We sought to investigate the effects of resolvin D1 on sepsis and to explore the mechanism of action. Six-to-eight-week-old male C57BL/6 mice were randomly divided into three groups: the sham group underwent the sham operation followed by tail vein injection of vehicle (0.1 % ethanol); the CLP group received vehicle (0.1 % ethanol) after CLP; the resolvin D1 group received resolvin D1 (100 ng) after CLP. Blood, peritoneal lavage fluid, and organs of mice were harvested 24 h after treatment for cytokine analysis, cell counts, bacterial cultures, histopathological studies, and apoptosis quantification. Compared with the vehicle control group, the survival rate and bacterial clearance of mice with sepsis induced by CLP were improved after resolvin D1 treatment, but the numbers of neutrophils in peritoneal lavage fluid, the inflammatory cytokines, the phosphorylation of the nuclear factor-κB (NF-κB) (P65) pathway, and the apoptosis rate of CD3(+) T lymphocytes of the thymus were suppressed. Resolvin D1 treatment improved survival in mice with sepsis induced by CLP, enhanced organism bacterial clearance, suppressed the increase of the numbers of neutrophils in peritoneal lavage fluid, reduced the release of inflammatory cytokines, and decreased the apoptosis rate of CD3(+) T lymphocytes of the thymus. These results suggest that resolvin D1 may attenuate the degree of inflammatory reaction in sepsis caused by CLP, without harming the host defense response.

Abstract
OBJECTIVE To examine the feasibility of allogeneic peripheral blood stem cell transplantation (Allo-PBSCT) for the hereditary haemolytic anemia (HHA). METHODS Allo-PBSCTs were performed on 3 patients with beta-thalassemia major and 1 patient with congenital idiopathic haemolytic anemia by the HLA-identical siblings' donors or 1 locus-mismatch parent. The harvested stem cell contained nucleated cells (4.7-14.4) X 10(8)/kg recipient weight, CD(34) (+) CD(38)(-) cells(4.8-32.9) X 10(6)/kg and colony-forming-unit-granulocyte-macrophages (CFU-GM)(3.22-9.8) X 10(5)/kg. The conditioning regimen consisted of busulfan, cyclophosphamide, melphalan, thiotepa, fludarabine and antithymocyte globulin (ATG). RESULTS All patients were engrafted and accomplished with the acute graft-versus-host disease (aGVHD). A patient had the controlled chronic GVHD. Three patients are survivals with ex-anemia; their Hb levels have been maintaining normality without transfusion. One died of the hepatic veno-occlusive disease. CONCLUSION Allo-PBSCT is an effective and a new way to treat beta-thalassemia major and congenital idiopathic haemolytic anemia.

Abstract
OBJECTIVE To evaluate the efficacy of allo-UCBT in thalassemia children. METHODS Five patients with beta-thalassemia major (genotypes were homozygote of beta41-42, beta654 and double heterozygosities of beta41-42/beta654, beta41-42/-28, beta654/-28, respectively) were treated by allo-UCBT. The median age was 3 year and ten month old (31/2 - 7 2/12). Four donor-recipient pairs were HLA-identical and one 1 locus mismatch. The patients received a median UCB nucleated cells (NC) of 5.5 x 10(7)/kg body weight [range (4.7 - 7.7) x 10(7)/kg] and CD(34)(+)CD(38)(-) cells 2.8 x 10(5)/kg [range (0.6 - 4.5) x 10(5)/kg] and CFU-GM 1.09 x 10(5)/kg [range (0.24 - 230.00) x 10(5)/kg]. The conditioning regimen consisted ofbusalphan 16 - 20 mg/kg, cyclophosphamide 180 - 200 mg/kg, horse antithymocyte globulin (ATG) 90 mg/kg or rabbit anti-lymphocyte globulin (ALG) 25 mg/kg and melphalan of 90 mg/m(2) was added to four cases. Cyclosporine A (CsA) alone was administered in 3 cases, and a combination of CsA and methotrexate in the other 2 cases. RESULTS Four cases were engrafted, but one rejected and recurred thalassemia state at day 60 past UCBT. One case had autologous reconstitution. The reconstitutions were found in all patients with neutrophils 0.5 x 10(9)/L at day 19 (14 - 22), platelets > 20 x 10(9)/L at day 37 (21 - 63). Two cases developed grade I and II acute GVHD respectively. None developed chronic GVHD. Three patients survived disease-freely (survival with ex-thalassemia state). The median follow-up was 18 months, the probability of survival was 100%. CONCLUSION Allo-UCBT could reconstitute hematopoiesis with low frequency and mild grade of GVHD. It is an effective treatment for thalassemia.

Abstract
We have isolated 462 bp of sequence termed ovarian-specific promoter 1 (OSP-1) that is part of a retrovirus-like element specifically expressed in the rat ovary. We have evaluated the ability of OSP-1 to activate gene expression in normal and neoplastic cell lines derived from the ovaries of rats and women. We have found that there was marked specificity in the ability of OSP-1 to drive reporter gene expression in an ovarian epithelial cell lineage manner. The expression of herpes simplex virus thymidine kinase (HSV-TK) under OSP-1 control was sufficiently ovarian cancer cell line specific to render ganciclovir approximately 50-fold more toxic in the A2780 human ovarian cancer cell line compared with clones of the HCT-116 and HT-29 colon cancer cell lines. Furthermore, ganciclovir had marked antitumor efficacy in vivo in severe combined immunodeficient mice bearing A2780OSP-1-HSV-TK as a s.c. xenograft. We suggest that these data support the use of OSP-1 as a tool to provide specificity to the gene therapy of ovarian cancer and to drive ovarian-specific oncogene expression for the creation of transgenic mouse models of ovarian cancer.

Abstract
OBJECTIVES A limitation to preclinical evaluation of possible anticancer therapy is the objective assessment of efficacy, especially in the presence of small tumor burden or inaccessible disease. This study is designed to test whether human secreted alkaline phosphatase (SEAP) could be used as a soluble marker for in vivo tumor burden. METHODS A SEAP expression construct under control of the CMV promoter was created. The SEAP activity in the conditioned medium was evaluated at 24 h and 48 h after the A2780 cell line was transiently transfected with the SEAP vector using Superfect reagent. Stable transfection of A2780 was accomplished by selection of transfectants in G418. SEAP activity of the stable transfectant was determined in conditioned medium and its relationship to tumor cell number was examined. A highly expressing stable transfectant was implanted into immunocompromised mice (2 x 10(6) subcutaneously and 5 x 10(6) intraperitoneally) and peripheral blood was obtained by orbital puncture every 5 days. The relationship between blood SEAP activity and tumor burden was studied. The usefulness of this marker in preclinical assessment of anticancer drug efficacy was evaluated by studying the plasma SEAP activity in xenografted mice treated or not treated with paclitaxel. RESULTS After transient transfection of the A2780 cell line (5 x 10(5)) with the plasmid, SEAP activity was found in the medium at 24 h (482.0 +/- 2.0 ng/ml) and 48 h (1296.0 +/- 1.0 ng/ml). The in vitro study using a stable transfectant demonstrated that SEAP activity was linearly related to cell numbers (r = 0.99). The in vivo study demonstrated that SEAP was detectable in plasma one day postinjection, long before measurable tumor or detectable intraperitoneal tumor was present. Once detectable SC tumor was present, the SEAP activity correlated well with tumor volume (r = 0. 94-0.97). The plasma SEAP level was reduced after xenografted mice were treated with paclitaxel (20 mg/kg, weekly x5) compared with untreated mice in both SC and IP tumor models (P = 0.05, P = 0.025, respectively). CONCLUSION These data suggest that the plasma SEAP activity can be used as an alternative to survival or tumor measurement in evaluating anticancer agents for efficacy, especially in the case of minimal or inaccessible disease.

Abstract
We previously reported cloning the rLot1 gene, and its human homolog (hLOT1), through analysis of differential gene expression in normal and malignant rat ovarian surface epithelial cells. Both human and rat ovarian carcinoma cell lines exhibited lost or decreased expression of this gene. Interestingly, the LOT1 gene localized at band q25 of human chromosome 6 which is a frequent site for LOH in many solid tumors including ovarian cancer. In this report we have further characterized the potential role of LOT1 in malignant transformation and developed evidence that the gene is a novel target of growth factor signaling pathway. Assays using transient transfections showed that LOT1 is a nuclear protein and may act as a transcription factor. In vitro and in vivo studies involving ovarian cancer cell lines revealed that expression of LOT1 is directly associated with inhibition of cellular proliferation and induction of morphological transformations. Additionally, we show that in normal rat ovarian surface epithelial cells Lot1 gene expression is responsive to growth factor stimulation. Its mRNA is strongly down-regulated by epidermal growth factor receptor (EGFR) ligands, namely EGF and TGF-alpha. Blocking the ligand-activated EGFR signal transduction pathway by the specific EGF receptor inhibitor, tyrphostin AG1478, and the MEK inhibitor, PD098059, restores the normal level of Lot1 gene expression. It appears that the regulation of Lot1 gene is unique to these ligands, as well as the growth promoting agent TPA, since other factors either did not affect Lot1 expression, or the effect was modest and transient. Altogether, the results suggest that Lot1 expression is primarily mediated via EGF receptor or a related pathway and it may regulate the growth promoting signals as a zinc-finger motif containing nuclear transcription factor.

Abstract
The value of magnetic resonance imaging (MRI) in the diagnosis and staging of endometrial carcinoma was studied in 43 cases of clinically suspected endometrial carcinoma and 7 normal women. All of the 43 cases showed abnormal endometria measured by MRI, among which were pathologically proven 40 cases of endometrial carcinoma, 2 cases of endometrial polyps and 1 case of adenomyosis. This suggested that MRI showed a high susceptibility in the diagnosis of endometrial carcinoma, and a lack of specificity. MRI could predict myometrial invasion, its accuracy being verified by surgico-pathological findings in 11 of 13 cases. MRI staging was correct in 10 of the 13 primarily operated cases, and only half of the clinical staging was in conformity with surgical staging. The results suggest that MRI is useful in the staging of endometrial carcinoma and therefore is of value in the choice of treatment planning, although it is not yet an ideal diagnostic aid to detect small metastatic pelvic lesions.
