Abstract
BACKGROUND The influence of SARS-CoV-2 infection after embryo transfer on early pregnancy outcomes in in vitro fertilization or intracytoplasmic sperm injection-embryo transfer treatment remains inadequately understood. This knowledge gap endures despite an abundance of studies investigating the repercussions of preceding SARS-CoV-2 infection on early pregnancy outcomes in spontaneous pregnancies. OBJECTIVE This study aimed to investigate the association between SARS-CoV-2 infection within 10 weeks after embryo transfer and early pregnancy outcomes in patients undergoing in vitro fertilization/intracytoplasmic sperm injection treatment. STUDY DESIGN This prospective cohort study was conducted at a single public in vitro fertilization center in China. Female patients aged 20 to 39 years, with a body mass index ranging from 18 to 30 kg/m2, undergoing in vitro fertilization/intracytoplasmic sperm injection treatment, were enrolled between September 2022 and December 2022, with follow-up extended until March 2023. The study tracked SARS-CoV-2 infection time (≤14 days, ≤28 days, and ≤10 weeks after embryo transfer), symptoms, vaccination status, the interval between vaccination and embryo transfer, and early pregnancy outcomes, encompassing biochemical pregnancy rate, implantation rate, clinical pregnancy rate, and early miscarriage rate. The study used single-factor analysis and multivariate logistic regression to examine the association between SARS-CoV-2 infection status, along with other relevant factors, and the early pregnancy outcomes. RESULTS A total of 857 female patients undergoing in vitro fertilization/intracytoplasmic sperm injection treatment were analyzed. In the first stage, SARS-CoV-2 infection within 14 days after embryo transfer did not have a significant negative association with the biochemical pregnancy rate (adjusted odds ratio, 0.74; 95% confidence interval, 0.51-1.09). In the second stage, SARS-CoV-2 infection within 28 days after embryo transfer had no significant association with the implantation rate (36.6% in infected vs 44.0% in uninfected group; P=.181). No statistically significant association was found with the clinical pregnancy rate after adjusting for confounding factors (adjusted odds ratio, 0.69; 95% confidence interval, 0.56-1.09). In the third stage, SARS-CoV-2 infection within 10 weeks after embryo transfer had no significant association with the early miscarriage rate (adjusted odds ratio, 0.77; 95% confidence interval, 0.35-1.71). CONCLUSION Our study suggests that SARS-CoV-2 infection within 10 weeks after embryo transfer may not be negatively associated with the biochemical pregnancy rate, implantation rate, clinical pregnancy rate, and early miscarriage rate in patients undergoing in vitro fertilization/intracytoplasmic sperm injection treatment. It is important to note that these findings are specific to the target population of in vitro fertilization/intracytoplasmic sperm injection patients aged 20 to 39 years, without previous SARS-CoV-2 infection, and with a body mass index of 18 to 30 kg/m2. This information offers valuable insights, addressing current concerns and providing a clearer understanding of the actual risk associated with SARS-CoV-2 infection after embryo transfer.

Abstract
In this retrospective study conducted at Sichuan Jinxin Xinan Women and Children's Hospital spanning January 2015 to December 2021, our objective was to investigate the impact of embryo cryopreservation duration on outcomes in frozen embryo transfer. Participants, totaling 47,006 cycles, were classified into 3 groups based on cryopreservation duration: ≤1 year (Group 1), 1 to 6 years (Group 2), and ≥6 years (Group 3). Employing various statistical analyses, including 1-way ANOVA, Kruskal-Wallis test, chi-square test, and a generalized estimating equation model, we rigorously adjusted for confounding factors. Primary outcomes encompassed clinical pregnancy rate and Live Birth Rate (LBR), while secondary outcomes included biochemical pregnancy rate, multiple pregnancy rate, ectopic pregnancy rate, early and late miscarriage rates, preterm birth rate, neonatal birth weight, weeks at birth, and newborn sex. Patient distribution across cryopreservation duration groups was as follows: Group 1 (40,461 cycles), Group 2 (6337 cycles), and Group 3 (208 cycles). Postcontrolling for confounding factors, Group 1 exhibited a decreased likelihood of achieving biochemical pregnancy rate, clinical pregnancy rate, and LBR (OR < 1, aOR < 1, P < .05). Furthermore, an elevated incidence of ectopic pregnancy was observed (OR > 1, aOR > 1), notably significant after 6 years of freezing time [aOR = 4.141, 95% confidence intervals (1.013-16.921), P = .05]. Cryopreservation exceeding 1 year was associated with an increased risk of early miscarriage and preterm birth (OR > 1, aOR > 1). No statistically significant differences were observed in birth weight or sex between groups. However, male infant birth rates were consistently higher than those of female infants across all groups. In conclusion, favorable pregnancy outcomes align with embryo cryopreservation durations within 1 year, while freezing for more than 1 year may diminish clinical pregnancy and LBRs, concurrently elevating the risk of ectopic pregnancy and preterm birth.

Abstract
Introduction Obesity has detrimental influences on women reproductive health. There is little experience in optimizing controlled ovarian hyperstimulation (COH) protocols to treat Chinese obese patients who are undergoing in vitro fertilization and embryo transfer (IVF-ET) therapy. Methods The clinical outcome differences were retrospectively analyzed among obese patients who received gonadotrophin-releasing hormone agonist (GnRH-a), GnRH antagonist (GnRH-ant), micro dose GnRH-a (mGnRH-a) and GnRH-a long protocol in IVF-ET cycle at Chengdu Jinjiang Hospital for Women's and Children's Health from January 2014 to December 2019. Results The transplantation rate of the GnRH-a long protocol group (59.1%) was higher than that of the GnRH-ant (25.9%) and mGnRH-a (36.7%) groups. The total live birth rate of the GnRH-a long protocol group (46.2%) was higher than that of the GnRH-a group (25.9%) and GnRH-ant group (40.3%). The total number of frozen embryos in the GnRH-ant group was higher than in the other groups (P < 0.05). After adjusting for confounding factors, the logistic regression analysis showed that the GnRH-a long protocol group had higher probabilities of biochemical pregnancy, clinical pregnancy, and live birth than the GnRH-a protocol group. The Gn dose in the mGnRH-a group was higher than the other three groups. Whether single or twin, there were similar neonatal outcomes among the four groups including premature birth rate, Apgar score, newborn weight, and length. Conclusion For young obese patients undergoing IVF-ET, the GnRH-a long protocol for COH gives better pregnancy outcomes.

Abstract
BACKGROUND The serum progesterone on human chorionic gonadotropin trigger day / metaphase II oocyte (P/MII) ratio might be a more predictable indicator of pregnancy and neonatal outcomes as compare to P/estradiol (E2) or P alone. Hence, we conducted a larger population study to compare the pregnancy and neonatal outcomes in the low and high P/MII ratio. METHODS A retrospective, single-center, larger population cohort study between January 2015 and August 2021. Calculate the threshold effect of P/MII ratio on clinical pregnancy rate according to the construct smooth curve fitting. Divide data into two groups by threshold for comparison. RESULTS 3566 fresh ICSI-ET cycles were included, in which 929 singleton delivery and 676 twin deliveries. Compare to P/MII ≤ 0.367 group, it indicated that the P/MII > 0.367 group had a lower clinical pregnancy rate and live birth rate, furthermore, a significantly higher rate of LBW and SGA were observed in the singleton and twin deliveries. No deleterious impact of high P/MII ratio on embryo quality and undesirable pregnancy outcomes was shown. CONCLUSIONS When P/MII is higher than 0.367, may have adverse impacts on pregnancy and neonatal outcomes for ICSI cycle.

Abstract
The management of patients with poor ovarian response (POR) remains a major challenge for fertility specialists in in vitro fertilization-embryo transfer (IVF-ET). In this retrospective cohort study, we aimed to evaluate the clinical effect of sequential transfer on pregnancy outcomes in patients with POR. A total of 3579 POR patients who underwent the first frozen embryo transfer (FET) cycle were enrolled from January 2018 to April 2021. The patients were divided into three groups according to the embryo transfer (ET) strategy adopted: a study group that included POR patients in whom a cleavage-stage embryo (day 3) and a blastocyst (day 5/6) were transferred (sequential transfer group), and two control groups in whom two cleavage-stage embryos (D3-dET group) or two blastocysts (D5/6-dET group) were transferred. The study group was matched with the control groups at a ratio of 1:4 by propensity score matching (PSM). The main pregnancy outcomes measured were the live birth rate and multiple pregnancy rate. After PSM, the live birth rate in the sequential transfer group was significantly higher than that in the D3-dET group (44.2% vs. 34.3%, P = 0.019), and was similar to that in the D5/6-dET group (44.2% vs. 45.3%; P = 0.90). In addition, there was no increase in the risk of multiple pregnancy among POR patients undergoing sequential transfer compared with both D3-dET (26.7% vs. 25.6%, P = 0.85) and D5/6-dET (26.7% vs. 28.4%, P = 0.97) groups. These findings imply that sequential transfer is an effective option for POR patients and could be utilized after careful consideration.

Abstract
Objectives Resuscitation transfer of embryos after elective cryopreservation has been widely applied in in vitro fertilization-embryo transfer (IVF-ET) therapy for human infertility or sterility owing to higher embryo implantation rates. This method separates oocyte retrieval from embryo transfer. The optimal time for frozen embryo transfer (FET) remains unknown. Therefore, this study mainly compares the advantages and disadvantages of delayed FET and immediate FET through retrospective analysis. Methods We analyzed real world data of patients who underwent resuscitation transplantation between October 2019 and July 2021 at the Reproductive Center of Chengdu Jinjiang Hospital for Women's and Children's Health. Propensity score matching was applied to control potential confounding factors. A total of 5,549 patients who received at least one FET were analyzed. Patients undergoing transplantation within 60 days of oocyte retrieval were included in the immediate FET group (n = 1,265) and those undergoing transplantation > 60 days after retrieval were included in the delayed FET group (n = 4,284). Results Live birth rates between the two groups were comparable (45.25% vs. 45.76%, p = 0.757). Moreover, no difference was observed in the rates of biochemical pregnancy (64.50% vs. 66.80%), clinical pregnancy (55.24% vs. 56.83%), ectopic pregnancy (1.47% vs. 1.39%), early miscarriage (14.41% vs. 16.20%), late miscarriage (2.21% vs. 2.09%), singleton premature delivery (16.67% vs. 18.29%), and neonatal deformity (1.97% vs. 1.80%). After stratifying the patients based on the type of embryo transferred, number of embryos transferred, FET protocol, and good prognosis criteria, live birth rates remained comparable between the two groups (p > 0.05). Conclusion Pregnancy outcomes were comparable between the immediate and delayed FET groups.

Abstract
OBJECTIVE To compare the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle outcomes between patients with low and normal serum luteinizing hormone (LH) levels on the day after a gonadotropin-releasing hormone agonist (GnRH-a) single trigger. We further investigated the efficacy of human chorionic gonadotropin (hCG) retrigger on IVF cycle outcomes in patients with low LH levels after GnRH-a single trigger. METHODS We retrospectively analyzed 957 infertile patients (tubal factor, ovulation disorders, male sperm factor, or unexplained infertility) who were treated with IVF/ICSI at the Chengdu Xinan Gynecology Hospital from July 2017 to December 2020. Patients received sufficient GnRH-a single trigger were divided into two groups based on the serum LH levels on the next day of trigger: normal serum LH levels (≥ 10 mIU/mL) group (control group, n = 906) and low LH levels (< 10 mIU/mL) group (experimental group, n = 51). And the efficacy of hCG retrigger on IVF/ICSI cycle outcomes in 10 patients with low LH levels after GnRH-a single trigger. RESULTS There were no significant differences in IVF/ICSI cycle outcomes, including egg yield, two pronuclei fertilization rate, excellent embryo rate, or live birth rate of frozen-thawed embryos between patients with low and normal LH levels after GnRH-a trigger. It showed significantly higher risk of ovarian hyperstimulation syndrome in the group of low LH levels [ 0.7%(1/137) vs. 8.5%(4/47), P = 0.016] compared with the group of normal LH levels who received GnRH-a single trigger. The hCG retrigger had no obvious efficacy on cycle outcomes in patients with low LH levels, including oocytes retrieved, fertilization rate, embryo conditions, and live birth rate of frozen-thawed cycles. CONCLUSION The IVF/ICSI cycle outcomes of patients with low LH levels on the day after GnRH-a administration were similar to those of patients with normal LH levels. Blood LH test might not be required on the day following the trigger. The hCG retrigger did not have any effect on the cycle outcomes, suggesting that immediate retriggering with hCG was unnecessary.

Abstract
BACKGROUND In frozen embryo transfer (FET), there is limited consensus on the best means of endometrial preparation in terms of the reproductive outcomes in women with polycystic ovary syndrome (PCOS). The present study aimed to compare the pregnancy and neonatal outcomes following artificial cycle FET (AC-FET) with or without gonadotropin-releasing hormone agonist (GnRH-a) pretreatment among women with PCOS. METHODS A total of 4503 FET cycles that satisfied the inclusion criteria were enrolled in this retrospective cohort study between 2015 and 2020. The GnRH-a group received GnRH-a pretreatment while the AC-FET group did not. Propensity score matching (PSM) method and multivariate logistic regression analysis were performed to adjust for potential confounding factors. RESULTS After PSM, women in the GnRH-a group suffered a significantly lower miscarriage rate (11.2% vs. 17.1%, P = 0.033) and a higher live birth rate (LBR) compared with those in the AC-FET group (63.1% vs. 56.8%, P = 0.043). No differences were observed in the rates of biochemical pregnancy, clinical pregnancy and ectopic pregnancy between the two groups. A higher mean gestational age at birth was observed in the GnRH-a group than in the AC-FET group (39.80 ± 2.01 vs. 38.17 ± 2.13, P = 0.009). The incidence of neonatal preterm birth (PTB) in the GnRH-a group was lower than that in the AC-FET group (7.4% vs. 14.9%, P = 0.009). Singleton newborns conceived after GnRH-a group were more likely to be small for gestational age (SGA) than those born after AC-FET group (16.4% vs. 6.8%, P = 0.009). However, no significant differences were found between the two groups in terms of mean birthweight, apgar score, the rates of macrosomia, large for gestational age and low birth weight. CONCLUSION(S) In women with PCOS who underwent AC-FET, GnRH-a pretreatment was significantly associated with a higher live birth rate and a reduced risk of neonatal PTB. However, there was a concomitant increase in the risk of developing SGA babies.

Abstract
BACKGROUND Childhood asthma has substantial effects on children's health. It is important to identify influencing factors in early life in the development of childhood asthma. We aim to evaluate the effects of early-life factors and indoor environmental exposure on childhood asthma in Chongqing, China. METHOD We designed a case-control study to enrol children with asthma aged 3 to < 14 years old and controls in Chongqing, China. The "Children's Early Life and Indoor Environment Survey" was used to collect the early-life factors and indoor environmental exposure of foetuses in utero and of infants during the first 3 years of life. A multivariate logistic regression model was used to evaluate the association between independent variables and childhood asthma and the interaction of early-life factors and environmental exposure. RESULTS A total of 160 asthma cases and 247 controls were included in this study. The mean ages of the cases and controls were 5.53 ± 1.88 and 5.72 ± 2.34 years, respectively (P = 0.192). Early-life factors and indoor environmental exposure were independently associated with childhood asthma. Infectious diseases of the respiratory system in children under 3 years old [adjusted odds ratio (OR) = 5.76, 95% confidence interval (CI) 2.49-13.30], bedroom air conditioner use (adjusted OR = 4.61, 95% CI 1.45-14.64), and bedroom dampness/mould (adjusted OR = 2.98, 95% CI 1.54-5.75) ranked as the three most significant exposures associated with the risk of childhood asthma. Other factors associated with an increased risk of childhood asthma included second-hand smoke exposure in early life (adjusted OR = 1.93, 95% CI 1.24-3.00), neonatal pneumonia (adjusted OR = 1.90, 95% CI 1.05-3.42) and maternal allergic diseases during pregnancy (adjusted OR = 2.13, 95% CI 1.10-4.10). The interaction effects of child second-hand smoke exposure with other covariates were not found to be statistically significant. CONCLUSIONS Early-life factors and indoor environmental exposure are closely related to childhood asthma in Chongqing, China. Further interventions and management in the early life of children should be considered to prevent and control childhood asthma in Chongqing and similar cities.

Abstract
BACKGROUND The GnRH agonist long-acting protocol and GnRH antagonist protocol are widely used in ovarian stimulation. Which protocol eliciting higher live birth rate for IVF/ICSI patients with different ages, different ovarian reserves and different body mass index (BMI) has not been studied. However, among these protocols, the one that elicits higher live birth in IVF/ICSI patients with different ages, ovarian reserves and body mass indexes (BMI) has not been identified. METHODS This was a retrospective cohort study about 8579 women who underwent the first IVF-ET from January, 2018 to August, 2021. Propensity Score Matching (PSM) was used to improve the comparability between two protocols. RESULTS After PSM, significant higher live birth rates were found in the GnRH agonist long-acting protocol compared to GnRH antagonist protocol (44.04% vs. 38.32%) (p<0.001). Stratified analysis showed that for those with AMH levels between 3 ng/ml and 6 ng/ml, with BMI ≥ 24 kg/m2 and were aged ≥ 30 years old, and for those women with BMI < 24kg/m2 and were aged ≥30 years whose AMH levels were ≤ 3ng/ml, the GnRH agonist long-acting protocol was more likely to elicit live births [OR (95%CI), 2.13(1.19,3.80)], [OR (95%CI), 1.41(1.05,1.91)]. However, among women with BMI ≥ 24kg/m2 and were aged ≥30 years whose AMH levels were ≤ 3ng/ml, the GnRH agonist long-acting protocol had a lower possibility of eliciting live births [OR (95%CI), 0.54(0.32,0.90)]. Also, among women with AMH levels between 3 ng/ml and 6 ng/ml, with BMI ≥ 24 kg/m2 and with age < 30 years and for those with AMH levels between 3 ng/ml and 6 ng/ml, regardless of age, and with BMI<24kg/m2,, the possibility of live births was similar between the two protocols [OR (95%CI), 1.06(0.60,1.89)], [OR (95%CI), 1.38(0.97,1.97)], [OR (95%CI), 0.99(0.72,1.37)]. Among the women with AMH levels ≤ 3 ng/ml and with were aged < 30years, regardless of BMI, the possibility of live birth was similar between the two protocols [OR (95%CI), 1.02(0.68,1.54)], [OR (95%CI), 1.43(0.68,2.98)]. Moreover, among women with AMH levels ≥ 6ng/ml, the possibility of live birth was similar between the two protocols [OR (95%CI),1.42(0.75,2.69)], [OR (95%CI),1.02(0.19,5.35)], [OR (95%CI), 1.68(0.81,3.51)], [OR (95%CI), 0.51(0.10,2.55)]. CONCLUSIONS The suitability of the GnRH agonist long-acting protocol or GnRH antagonist protocol to infertility patients is dependent on specific biological characteristics of the patients.

Abstract
BACKGROUND Mental health disorders are highly prevalent in polycystic ovary syndrome (PCOS) cases. The etiology for anxiety/depression in women with PCOS still remains unclear, due to conflicting results. AIM To examine whether an association exists between the mental health of Chinese women with PCOS and various indicators such as their disease characteristics, biochemistry results and sleep status. METHODS During July 2018 and January 2020, our study included a total of 433 women diagnosed with PCOS at Chongqing Hospital of Traditional Chinese Medicine. Sleep-related variables were evaluated by the Pittsburgh Sleep Quality Index (PSQI), anxiety and depression values were quantified by the Hospital Anxiety and Depression Scale (HADS), and biochemistry results were collected from the medical records of the patients. RESULTS 26.6% patients resulted as positive anxiety and 23.6% as positive depression. We found significant associations between anxiety/depression status and sleep conditions of PCOS patients. More specifically, anxiety significantly associated with sleep quality OR (95%CI) = 1.611 (1.147-2.261), sleep disturbance 2.326 (1.468-3.685) and daytime dysfunction 1.457 (1.122-1.891). Similarly, depression significantly associated with sleep quality 1.467 (1.043-2.063), sleep disturbance 1.624 (1.030-2.561) and daytime dysfunction 1.406 (1.077-1.836). There was no association detected between mental health and disease characteristics, as well as reproductive and metabolic indicators in PCOS. LIMITATION Cross-sectional nature of the data prevents causal associations, selection bias of a hospital-based population. CONCLUSIONS Sleep-related disorders might be involved in the etiology and development of the anxiety/depression observed in PCOS cases. We propose that management of sleep disorders should be an integral part of the disease management of women with PCOS.

Abstract
When face-centered cubic (FCC) metals and alloys with low stacking fault energy (SFE) are irradiated by high-energy particles or deformed at high speed, stacking fault tetrahedra (SFTs), which are a type of vacancy cluster defect, are often formed. Therefore, SFTs were expected to form in the CoCrFeMnNi equiatomic high-entropy alloy (HEA). However, no SFT was observed in the CoCrFeMnNi HEA with high-speed plastic deformation even after annealing at 873 K. To elucidate this mechanism, the binding energy of vacancy clusters in the CoCrFeMnNi HEA was calculated based on first principles. The binding energy of the di-vacancy cluster was positive (average of 0.25 eV), while that of the tri-vacancy cluster was negative (average of - 0.44 eV), suggesting that the possibility of formation of a tri-vacancy cluster was low. The inability to form a cluster containing three vacancies is attributed to the excellent irradiation resistance of the CoCrFeMnNi HEA. However, if an extra vacancy is added to a tri-vacancy cluster (with negative binding energy), the binding energy of the subsequent tetra-vacancy cluster may become positive. This suggests that it is possible to form vacancy clusters in the CoCrFeMnNi HEA when high-energy ion or neutron irradiation causes cascade damage.

Abstract
Abstract
Anti-androgenic endocrine-disrupting chemicals (EDCs) can cross the placenta to modify early offspring sexual dimorphic markers. These changes are linked to anogenital distance (AGD), which is an androgen-sensitive anthropometric parameter used as a biomarker of perineal growth and caudal migration of the genital tubercle. This review aimed to summarize strength of evidence for associations of in utero exposure to EDCs with AGD and to identify gaps and limitations in the literature so as to inform future research. We performed an electronic search of English literature in September 2019 in medical literature analysis and retrieval system online (MEDLINE), Web of Science and Toxline. We included epidemiological studies that examined in utero exposure to persistent and nonpersistent EDCs and considered AGD in offspring as an outcome. Our review contained 16 investigations examining exposure to persistent EDCs (nine studies) and nonpersistent EDCs (seven studies). Some individual studies reported an inverse association between exposure to bisphenol A (BPA), dioxins, perfluoroalkyl substances, and organochlorides and AGD in both male and female offspring. Meta-analysis of three studies found a small reduction of AGD in female offspring exposed to BPA. The number of studies per chemical is small, and number of subjects examined is limited; so, replication of these results is needed. To achieve more specificity and better replication of results, future studies should establish the association of nonpersistent EDCs using multiple urine samples, evaluate the cumulative impact of exposure to a mixture of anti-androgenic chemicals, and offer adequate consideration of more maternal- and children-related confounding factors.

Abstract
Bladder cancer has a high recurrence rate and requires adjuvant intravesical management after surgery. The use of traditional agents for bladder cancer therapy is constrained by their toxicity and limited efficacy. This emphasizes the need for the development of safer, more effective compounds such as instillation agents. Curcumin is the major component of turmeric, the powdered root of Curcuma longa, which is known for its anti-inflammatory, anti-oxidant and anticancer properties. First, a microarray profiling and qPCR analysis were conducted in the T24 and SV-HUC-1 cell lines. Then, we examined the potential tumorigenicity of miR-7641 in the T24 and SV-HUC-1 cell lines with or without curcumin. Western blot analysis showed that p16 is a target of miR-7641 in T24 cells. We found that, for the first time, curcumin directly downregulates a tumor-promoting microRNA (miRNA), miR-7641, in bladder cancer, which has tumor-promoting characteristics. Curcumin induces the downregulation of miR-7641 and subsequent upregulation of p16 which is a target of miR-7641 at the post-transcriptional level, which leads to the decreased invasion and increased apoptosis of bladder cancer cells. This is the first report to show a direct effect of curcumin on inducing changes in a miRNA suppressor with direct anticancer consequences in bladder cancer. Our study shows that curcumin may be a candidate agent for the clinical management of non-muscle-invasive bladder cancer.

Abstract
AIM: To observe the change in biliary motility in rats with severe acute pancreatitis and study its effect.
METHODS: Severe acute pancreatitis was induced in 28 male Sprague-Dawley rats by injection of sodium taurocholate into the pancreatobiliary duct. These rats were randomly divided into an experiment group (n = 14) and a control group (n = 14). Another 14 male SD rats injected with saline served as a sham operation group (SO group, n = 14). The experiment group was pretreated by intraperitoneal injection of anisodamine at 20 mg/kg. The control group was pretreated with saline. Twenty-four hours after operation, quantitative 99mTc-EHIDA hepatobiliary dynamic imaging was performed in each group. Plasma levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and endotoxin (ET) were detected, and the levels of cholecystokinin 8 (CCK8) in plasma, gallbladder and duodenal tissues were also measured. Abdominal viscera bacterial translocation rates were compared among these groups.
RESULTS: In comparison with the SO group and experiment group, a significant delay in duodenal appearance time (DAT) was noted in the control group (56.73 s ± 12.34 s vs 48.44 s ± 11.12 s, 29.52 s ± 11.83 s). A lower level of CCK8 in duodenal tissue was found in the control group than in the SO group and experiment group (5.24 pg/mL ± 0.56 pg/mL vs 5.81 pg/mL ± 0.45 pg/mL, 6.25 pg/mL ± 0.53 pg/mL). The levels of TNF-α, IL-1β, and ET were significantly higher in the control group and experiment group at 24 h after operation than in the SO group (P < 0.05 for all). The levels of TNF-α and ET were significantly lower in the experiment group than in the control group (ET: 0.148 EU/mL ± 0.032 EU/mL vs 0.320 EU/mL ± 0026 EU/mL, P = 0.040; TNF-α: 89.24 pg/mL ± 34.45 pg/mL vs 123.18 pg/mL ± 41.24 pg/mL, P = 0.049). The abdominal viscera bacterial translocation rate was significantly higher in the control group than in the other two groups (0.714% vs 0.573%, 0.143%, P < 0.05).
CONCLUSION: The inhibition of biliary motility was observed in rats with acute pancreatitis, and the change in biliary motility may promote viscera bacterial translocation.

Abstract
AIM: To observe the effects of anisodamine and gabexate mesilate on biliary dynamics in patients after biliary operation.
METHODS: Sixty-five patients after choledochotomy were randomly divided into control group (n = 20), anisodamine treatment group (n = 22) and gabexate mesilate treatment group (n = 23). Plasma endotoxin level and bile duct pressure were measured on days 1, 2, 3, 4, 5 and 7 after operation, respectively. Hepatobiliary function was evaluated using quantitative 99mTc- EHIDA hepatobiliary scintigraphy on days 3 and 7 after operation.
RESULTS: The bile duct pressure in patients in the gabexate mesilate treatment group was lower than that in the control group on days 1, 2 and 3 after operation (1.76 ± 0.20 kPa vs 1.84 ± 0.28 kPa, 1.60 ± 0.221 kPa vs 1.86 ± 0.20 kPa, and 1.56 ± 0.22 kPa vs 1.74 ± 0.24 kPa, respectively; all P < 0.05). Plasma endotoxin levels in patients in the two treatment groups were lower than those in the control group on days 3 and 4 after operation (all P < 0.05). On day 3, the rates of duodenal appearance over 30 min in the two treatment groups were significant higher than that in the control group (P = 0.026 and 0.018, respectively). However, no significant differences were noted in the time to peak activity (Tmax) and the half-time of excretion (T1/2) of the liver and common bile duct among the three groups.
CONCLUSION: Anisodamine and gabexate mesilate can promote bile excretion and reduce plasma endotoxin level in the early period after choledochotomy perhaps through improving the function of sphincter of oddi.

Abstract
OBJECTIVE Antigene therapy targeting only one oncogene has made much progress although it still has some limitations. To explore the potential for antigene therapy in uterine endometrial cancer, we examined the in vitro inhibitory effects of liposmal anti-sense phosphorothioate oligonucleotides targeting c-erbB-2 in the human uterine endometrial cancer HEC-1A cell line. METHODS 1) To detect c-erbB-2 protein expression on HEC-1A cell membranes by immunohisto- chemistry. 2) To assay cellular growth inhibition by MTT after transfecting 0.1-0.6 microM ASODN. 3) To observe cellular and ultra-structural changes under transmission electron microscope and to assay the cellular apoptotic rate by flow cytometry and c-erbB-2 mRNA, and protein expression by RT-PCR and Western blot after transfecting 0.3 microM ASODN. RESULTS 1) c-erbB-2 protein expression was positive on HEC-1A cell membranes. 2) With the increase of the transfecting ASODN concentration from 0.1-0.6 microM, HEC-1A cellular growth inhibition was also enhanced. The results of MTT showed that when the transfecting concentration of ASODN was 0.3 microM, the HEC-1A cellular growth inhibition rate was 50% while when the transfecting concentration of ASODN was 0.6 microM, the HEC-1A cell growth inhibition rate was 75%. 3) When the concentration of transfecting ASODNs was 0.3 microM, there were obvious vacuolar degenerations in the plasma of HEC-1A cells, disappearance of organelle and nuclear structure and obvious shrinkage of nuclei under transmission electron microscope. The cellular apoptotic rate was 62.80%, while c-erbB-2 mRNA and protein expression were 47.18% and 33.60%, respectively, compared with those of the normal control cells. CONCLUSION Transfecting c-erbB-2 ASODNs can obviously suppress the mRNA and protein expression in HEC-1A cells, cause cellular apoptosis and inhibit cell growth. It may be a more useful gene therapy for endometrial cancer.

Abstract
AIM: To assay the content differences of hemorphins between hepatocellular carcinoma (HCC) and normal liver tissues, and to explore the role of hemorphins in HCC.
METHODS: The tissue samples were obtained from 12 patients with HCC, and peptides were isolated by mild acid elution from the surfaces of hepatocarcinoma and normal hepatic cells. The mixtures of peptides were analyzed by high performance liquid chromatography (HPLC) and mass spectrometer (MS). A differential comparison was made on the fractions of peptides between HCC and normal liver cells to screen some tumor-specific peptides. Finally, human hepatocarcinoma cell line HLE was treated with different concentrations of the obtained peptides (0, 10-7, 10-8, 10-9, 10-10, 10-11, 10-12 mol/L), and the growth and apoptosis of HLE cells were detected by MTT assay and flow cytometry (FCM), respectively.
RESULTS: An opioid peptide Leu-Val-Val (LVV)-hemorphin-6 with Mr1160.76 was identified on the surfaces of HCC cells in 7 patients. LVV-hemorphin-6 inhibited the growth of HLE cells at different concentrations, especially at 10-7 and 10-8 mol/L (24 h: 10-7vs 10-8: P = 0.044, 10-8vs 10-9: P = 0.047; 48 h: 10-7vs 10-8: P = 0.031, 10-8vs 10-9: P = 0.040). Meanwhile, LVV-hemorphin-6 induced apoptosis of HLE cells and the apoptosis rates were 0.38% ± 0.09%, 20.23% ± 1.25%, 12.64% ± 2.15%, 1.65% ± 0.34%, when 0, 10-7, 10-8, 10-9 mol/L LVV-hemorphin-6 were used, respectively. However, naloxone could inhibit the above effect and the apoptosis rates were 0.41% ± 0.11%, 1.23% ± 0.45%, 0.98% ± 0.55%, 1.34% ± 0.43%, when the corresponding concentrations were used. The apoptosis rates were significantly different between the two groups (P < 0.05) as 10-7 and 10-8 mol/L LVV-hemorphin-6 were used.
CONCLUSION: LVV-hemorphin-6 may be a product in the pathophysiological process of hepatocellular carcinoma, and it has suppressive effects on HCC cells by activating opiate receptors.

Abstract
AIM: To detect the naturally processed antigenic peptides of melanoma antigen gene (MAGE) in tissues of hepatocellular carcinoma (HCC) by the technology of mass spectrometry (MS) and the strategy of differential analysis.
METHODS: Epitope prediction was performed to select HLA-A2-restricted protein sequence of MAGE-1 and MAGE-3 (theoretic peptides) to serve as the targets for MS screening. Peptides were isolated by mild acid elution from the surfaces of HCC cells and non-neoplastic liver cells, which were obtained from the same patient with HCC. Then the mixtures of peptides were fractionated by HPLC and a differential comparison was made between the two kinds of cells. Finally, the fractions contained tumor-specific peptides were analyzed by MS.
RESULTS: Eighty target peptides were selected after epitope prediction. Two naturally processed peptides of MAGE antigen were detected from HCC samples: FLWGPRALV (MAGE-3271-279) and FPSLREAAL (MAGE-1294-302). They were from peak 45.246 and 34.801, and the m/z was 1 058.49 and 1 003.62 respectively.
CONCLUSION: It is the first evidence that naturally presented peptides of MAGE antigen can be isolated and identified from the tumor tissues. MS-based approach can determine naturally processed peptides of tumor antigen rapidly and precisely, which is important in epitope identification and vaccine designation.

Abstract
In the absence of efficient systemic chemotherapy, immunotherapy is considered a hopeful treatment for controlling recurrence of hepatocellular carcinoma (HCC). The identification of proper antigenic peptides presented by MHC class I molecules is a critical step for the development of therapeutic vaccines against tumors. Currently, the "reverse immunology" approach is the most commonly used technique in the identification of the tumor-associated T cell epitopes. However, it is based on T cell dependent approach and cannot fully reflect the actual presentation of epitope in tumor in vivo. In the present study, we managed to identify the naturally presented MAGE epitopes of HCC directly by epitope prediction, HPLC differential analysis and MS detection. We successfully detected a naturally processed peptide FLWGPRALV (MAGE-3(271-279), HLA-A2-restricted) with an estimated number of 38-39 copies/cell in HCC. To our knowledge, this is the first evidence that the naturally processed MAGE-3(271-279) can be isolated and identified from the tumor tissue of HCC patient. Furthermore, specific CD8(+) T cell responses to this epitope were also found after tumor relapse by IFN-gamma release Cytospot and tetramer assay indicating that MAGE-3(271-279) was indeed presented by HCC cells in vivo. In addition, another new antigen peptide was found, which may be derived from MAGE-1. Our findings demonstrate the potential of the direct approach for identification of tumor-associated epitopes. This approach may become a useful tool for the development of vaccine against cancer in the future.

Abstract
AIM/HYPOTHESIS The characteristics of insulin binding to its receptors have been extensively studied by the radioligand binding assay. We used fluorescence correlation spectroscopy to determine the distribution of diffusion times and further novel data on the kinetics of insulin's binding to its receptor. METHODS Cultured human renal tubular cells (HRTC) were incubated with tetramethyl rhodamine labelled insulin (Rh-Ins) for 60 min. Fluorescence intensity fluctuations and autocorrelation functions for Rh-Ins, free in the incubation medium and bound to the cell membrane, were studied at single-molecule detection sensitivity in a 0.2 fL confocal volume. RESULTS Measurements at the cell membrane revealed Rh-Ins binding with at least two diffusion components (diffusion times tauD1 = 0.8 ms, tauD2 = 20 ms) and corresponding weight fractions of y1 = 0.43 and y2 = 0.42. Specificity of the binding was shown by the dislocation of bound Rh-Ins when excess unlabelled insulin was added. Scatchard analysis showed a nonlinear plot, revealing two binding processes with different affinities (Kass approximately 2 x 10(10) M(-1) and approximately 1 x 10(9) M(-1), respectively). CONCLUSION/INTERPRETATION The fluorescence correlation spectroscopy results show two classes of binding sites with different affinities for insulin, or interactions between receptor sites consistent with negative cooperativity. This conclusion is in agreement with studies of insulin binding using radioligand binding assays. Because of its high sensitivity (single molecule detection), FCS, provides additional data allowing a more precise evaluation of the kinetics of ligand-receptor interactions at low expression levels in living cells.

Abstract
Canine adenovirus type 1 (CAV-1) and type 2 (CAV-2) can be categorized in the laboratory by haemagglutination and neutralization tests, but they are difficult to differentiate from each other in specimens, especially when infection occurs in the digestive tract. The object of this study was to develop a simple method of detecting and differentiating them. One pair of common primers was designed and synthesized according to the sequences of the E3 and flanking regions and a polymerase chain reaction (PCR) assay was established using these two primers to amplify the virus-specific DNA fragment from clinical specimens as well as from cell cultures. After elecctrophoresis, under the same amplification conditions, 508 bp and 1030 bp PCR products were observed for CAV-1 and CAV-2, respectively. These were further shown to be adenovirus specific by dot hybridization and sequencing. As only one pair of primers was involved in the PCR procedure, it was faster and easier to perform than any of the other assays used for detecting canine adenovirus, making it applicable in the rapid confirmation of diagnosis and differentiation of the two types of canine adenoviruses.

Abstract
OBJECTIVES To study the impact of the CYP2D6*10 allele on the disposition of nortriptyline in Chinese subjects. METHODS A single dose of 25 mg nortriptyline was given orally to 15 healthy Chinese volunteers who were classified as extensive metabolizers after phenotyping with debrisoquin (INN, debrisoquine) and who were genotyped by allele-specific polymerase chain reaction. Five subjects were homozygous for CYP2D6*1, 5 subjects were homozygous for CYP2D6*10, and 5 subjects were heterozygous for these 2 alleles. Plasma concentrations of nortriptyline and its main metabolite 10-hydroxynortriptyline were measured by liquid chromatography-mass spectrometry, and the pharmacokinetics were studied during 168 hours after the dose. RESULTS Subjects who were homozygous for CYP2D6*10 had significantly higher total areas under the plasma concentration-time curve (AUC), lower apparent oral clearances, and longer mean plasma half-life of nortriptyline than subjects in the CYP2D6*1/*1 and the heterozygous groups. For 10-hydroxynortriptyline, the AUC was lower and the plasma half-life was longer in subjects who were homozygous for CYP2D6*10 than in subjects in the other 2 groups. CONCLUSION The CYP2D6*10 allele in Chinese subjects was associated with significantly higher plasma levels of nortriptyline compared with the CYP2D6*1 allele because of an impaired metabolism of nortriptyline to 10-hydroxynortriptyline, particularly in the subjects with the CYP2D6*10/*10 genotype. The results suggest that genotyping of CYP2D6 may be a useful tool in predicting the pharmacokinetics of nortriptyline.
