Abstract
Objective: To extract the differentially expressed key genes of primary biliary cholangitis (PBC) using bioinformatics methods, so as to provide information for further study into the mechanism. Methods: The GSE119600 dataset was downloaded from the GEO database to obtain differentially expressed genes. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed for differentially expressed genes. Protein-protein interaction (PPI) network reconstruction, Cytoscape software visualization, and core gene screening were performed. The area under the receiver operating characteristic curve (ROC AUC) was used to assess the diagnostic effectiveness of genes and plot the pROC software package. The x-Cell software was used to calculate the enrichment score of 34 immune cells in each sample. Finally, four key genes (PSMA4, PSMA1, PSMB1, and PSMA3) were selected. Blood samples were analyzed using the qPCR method. Results:: A total of 373 immune-related differentially expressed genes were identified. Eight genes (PSMC6, PSMB2, PSMB1, PSMA3, PSMA4, PSMA1, PSMD7, and PSMB5) were screened from the 178 nodes and 596 edges as hub genes of the PPI network, which were significantly related to amino acid metabolism, hematopoietic stem cell differentiation, cell cycle, and immune processes. PSMA4, PSMA1, PSMB1, and PSMA3 were defined as immunological biomarkers for PBC with an AUC value of the ROC curve > 0.7. Immunoinfiltrating cell analysis showed that the proportion of eosinophils was significantly higher in PBC patients compared to the control group, whereas the proportion of CD4+ memory T cells, plasma cells, Th2 cells, and cDC cells was significantly lower in PBC patients than the control group. Plasma cells were associated with all four immunological biomarkers. Seven PBC patients and seven healthy subjects were selected for peripheral blood qPCR validation, which demonstrates that PSMB1, PSMA3, PSMA1, and PSMA4 levels were significantly lower in PBC patients than healthy subjects, with a statistically significant difference. Conclusion:: Bioinformatics screened eight key genes, of which four were key immunological markers and may serve as a basis for clinical diagnosis and mechanism exploration.

Abstract
BACKGROUND In China, the identification rate and treatment rate of mental disorders are low, and there are few surveys on the prevalence of mental disorders among college students using diagnostic tools such as Mini-International Neuropsychiatric Interview (MINI), so the prevalence and treatment of mental disorders among college students are unclear.
AIM To estimate prevalence of mental disorders among medical students in Hebei Province, and provide guidance for improving their mental health.
METHODS This was a cross-sectional study based on an Internet-based survey. Three levels of medical students in Hebei Province were randomly selected (by cluster sampling) for screening. Using the information network assessment system, the subjects scanned the 2D code with their mobile phones, clicked to sign the informed consent, and answered a scale. A self-designed general status questionnaire was used to collect information about age, gender, ethnicity, grade, and origin of students. The MINI 5.0. was used to investigate mental disorders. Data analysis was performed with SPSS software. Statistically significant findings were determined using a two-tailed P value of 0.05.
RESULTS A total of 7117 subjects completed the survey between October 11 and November 7, 2021. The estimated prevalence of any mental disorders within 12 mo was 7.4%. Mood disorders were the most common category (4.3%), followed by anxiety disorders (3.9%); 15.0% had been to psychological counseling, while only 5.7% had been to a psychiatric consultation, and only 10% had received drug therapy in the past 12 mo.
CONCLUSION Although the estimated prevalence of mental disorders in medical students is lower than in the general population, the rate of adequate treatment is low. We determined that improving the mental health of medical students is an urgent matter.

Abstract
The past decade of studies showed that parenting behaviors (e.g., warmth, autonomy, and control) were associated with children’s executive functions (EF) in the early years. However, different measurement methods had been used across studies, making it hard to compare the effects of parenting on EF across studies. Therefore, the present study aimed to examine the effect of the measurement methods on the relationship between maternal parenting behaviors and children’s EF among a group of Chinese preschoolers. One hundred and twenty-six children (62 boys; Mage = 48.65 months) were assessed with direct measures on children’s EF (inhibition and working memory tasks), and parenting behaviors of their mothers during interaction with children were observed and coded. Mothers also reported their parenting practices and children’s difficulties in executive functions. The results of structural equation modeling showed that the latent performance-based EF was uniquely predicted by maternal positive control and negative control in mother–child interaction, while children’s EF difficulties reported by mothers were predicted by mother-reported warmth and support, and autonomy granting. Overall, the results suggest that the relationship between maternal parenting and children’s EF depends on the measurement methods of parenting and executive functions.

Abstract
OBJECTIVE This study aimed to investigate the long-term effects of early stress by Tangshan earthquake on symptoms of depression in adulthood. METHOD A total of 1534 volunteers born and raised in Tangshan were investigated; finally, 1328 subjects were enrolled in the study. They were divided into three groups according to their birth dates: infant exposure, prenatal exposure, and non-exposure. The questionnaires and psychological evaluation of all subjects were completed using a one-on-one psychological test. RESULTS The rate of depressive symptoms in the prenatal exposure group was the highest, and the lowest in the non-exposure group, with statistical differences among the three groups (P = 0.002). Moreover, the incidences of depressed mood, suicide ideation and work and loss of interest in the prenatal exposure group were significantly higher than those in the infant exposure group and the non-exposure group (P = 0.008, P = 0.001, P = 0.038, respectively). Multiple logistic regression analysis showed that male could be a protective factor for symptoms of depression in adulthood, and earthquake exposure was an important predictor of the incidence of depression symptoms. CONCLUSIONS Fetal or infancy exposure to earthquake might correlate to depression symptoms in adulthood.

Abstract
BACKGROUND The critical diagnostic criteria for esophagogastric junction outflow obstruction (EGJOO) were published in the latest Chicago Classification version 4.0 (CCv4.0). In addition to the previous criterion [elevated integrated relaxation pressure (IRP) in supine position], manometric diagnosis of EGJOO requires meeting the criteria of elevated median-IRP during upright wet swallows and elevated intrabolus pressure. However, with the diagnostic criteria modification, the change in manometric features of EGJOO remained unclear.
AIM To evaluate the esophageal motility characteristics of patients with EGJOO and select valuable parameters for confirming the diagnosis of EGJOO.
METHODS We performed a retrospective analysis of 370 patients who underwent high-resolution manometry with 5 mL water swallows × 10 in supine, × 5 in upright position and the rapid drink challenge (RDC) with 200 mL water from November 2016 to November 2021 at Peking University First Hospital. Fifty-one patients with elevated integrated supine IRP and evidence of peristalsis were enrolled, with 24 patients meeting the updated manometric EGJOO diagnosis (CCv4.0) as the EGJOO group and 27 patients not meeting the updated EGJOO criteria as the isolated supine IRP elevated group (either normal median IRP in upright position or less than 20% of supine swallows with elevated IBP). Forty-six patients with normal manometric features were collected as the normal high-resolution manometry (HRM) group. Upper esophageal sphincter (UES), esophageal body, and lower esophageal sphincter (LES) parameters were compared between groups.
RESULTS Compared with the normal HRM group, patients with EGJOO (CCv4.0) had significantly lower proximal esophageal contractile integral (PECI) and proximal esophageal length (PEL), with elevated IRP on RDC (P < 0.05 for each comparison), while isolated supine IRP elevated patients had no such feature. Patients with EGJOO also had more significant abnormalities in the esophagogastric junction than isolated supine IRP elevated patients, including higher LES resting pressure (LESP), intrabolus pressure, median supine IRP, median upright IRP, and IRP on RDC (P < 0.05 for each comparison). Patients with dysphagia had significantly lower PECI and PEL than patients without dysphagia among the fifty-one with elevated supine IRP. Further multivariate analysis revealed that PEL, LESP, and IRP on RDC are factors associated with EGJOO. The receiver-operating characteristic analysis showed UES nadir pressure, PEL, PECI, LESP, and IRP on RDC are parameters supportive for confirming the diagnosis of EGJOO.
CONCLUSION Based on CCv4.0, patients with EGJOO have more severe esophagogastric junction dysfunction and are implicated in the proximal esophagus. Additionally, several parameters are supportive for confirming the diagnosis of EGJOO.

Abstract
Breast cancer is a complex cancer which includes many different subtypes. Identifying prognostic modules, i.e., functionally related gene networks that play crucial roles in cancer development is essential in breast cancer study. Different subtypes of breast cancer correspond to different treatment methods. The purpose of this study is to use a new method to divide breast cancer into different prognostic modules, so as to provide scientific basis for improving clinical management. The method is based on comparing similarities between modules detected from different weighted gene co-expression networks. The method was applied on genomic data of breast cancer from The Cancer Genome Atlas database and was applied to select differential modules between two groups of patients with significant differences in survival times. It was compared with a previously proposed module selection method. The result shows that our method outperforms the previously proposed one. Moreover, within the identified two differential modules, the first one is highly enriched with genes involved in hormone responds, the second one is highly related with biological process engaged in M-phase. The two modules were further validated by log-rank test in the validation dataset GSE3494. Both of the two modules show significantly different with p-values less than 0.02. The identified two modules confirmed previous findings including importance of biological networks in breast cancer involved in hormone response and M-phase. Out of the top twenty hub genes in the two modules, fifteen genes were previously shown to be prognostic markers for breast cancer.

Abstract
OBJECTIVE To systematically review the effects of moxibustion on serum cytokines in experimental animals with rheumatoid arthritis. METHODS PubMed, Embase, Web of Science, The Cochrane Library, CNKI, VIP, Wanfang Data, and CBM were searched for animal experiments on moxibustion intervention for rheumatoid arthritis. Related data were extracted, and RevMan 5.3 was used to perform a meta-analysis of outcome measures, including serum tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), interleukin-6 (IL-6), vascular endothelial growth factor (VEGF), interleukin-17 (IL-17), interleukin-2 (IL-2), interferon-γ (IFN-γ), receptor activator of nuclear factor-kappa B ligand (RANKL), transforming growth factor-β (TGF-β), and degree of swelling of diseased joint. RESULTS A total of 18 studies were included. The detection methods included radioimmunoassay and ELISA and the experimental animal species included rats and rabbits. The studies on serum TNF-α and degree of swelling of diseased joint had publication bias. Meta-analysis showed that the moxibustion group had significant reductions in the serum levels of TNF-α, IL-1, IL-2, IL-6, VEGF, IL-17, and RANKL, significant increases in the serum levels of TGF-β and IFN-γ, and a significant reduction in the degree of swelling of diseased joints in model animals. CONCLUSION Moxibustion can effectively regulate levels of the serum cytokines in experimental animals of rheumatoid arthritis and thus reduce inflammatory response and alleviate the swelling of diseased joints.

Abstract
The objective of the current study was to determine whether exposure to earthquake stress during pregnancy and infancy impacted on the risk of chronic adult health problems. All subjects were divided into three groups: the infant exposure group, the fetus exposure group, and the non-exposure group. All subjects completed a standardized interview that included questions on demographic information, traumatic experiences during the earthquake, Anthropomorphic parameters such as body height, weight, and blood pressure were measured. Traumatic events in childhood and adulthood were assessed by the Childhood Trauma Questionnaire (CTQ) and Life Event Scale (LES), respectively. Totally1325 subjects were included; 399 subjects experienced the earthquake as fetuses, 374 subjects who experienced the earthquake as infants and 552 subjects did not experience the earthquake. The three groups were comparable in sociodemographic and baseline characteristics except age (Infant exposure vs Prenatal exposure vs No exposure = 39.5 ± 0.6 vs 38.5 ± 0.8 vs 37.5 ± 0.9, p < .001). Fetal and infant exposure to earthquakes was associated with elevated systolic blood pressure (both were + 3 mm Hg, p < .001). After adjustment for covariates, earthquake exposure in infants (odds ratio [OR] = 2.010, 95% confidence interval [CI] = 1.216 ~ 3.322) and fetuses (OR = 1.509, 95% CI = 1.014 ~ 2.248) was a significant and independent risk factor for hypertension. Earthquake expose in fetuses was a significant and independent risk factor for diabetes (OR = 2.307, 95% CI = 1.136 ~ 4.686). Earthquake exposure in infants and fetuses is a significant and independent risk factor for hypertension. Earthquake exposure in fetuses is significant and independent risk factor for diabetes.

Abstract
Low expression levels of CREB-binding protein (CREBBP) have been demonstrated to be associated with high minimal residual disease at the end of induction therapy and adverse long-term outcomes in pediatric patients with acute lymphoblastic leukemia (ALL). However, the effect of low CREBBP expression on the prognosis of ALL has not yet been investigated. In the present study, CREBBP was downregulated and overexpressed in ALL cell lines (Jurkat and Reh). Sensitivity to chemotherapy and cell proliferation activity was determined via a Cell Counting Kit-8 assay. Cell cycle analysis was performed using flow cytometry. Immunofluorescence confocal microscopy and co-immunoprecipitation (Co-IP) assays were performed to determine the interaction between CREBBP and E2F transcription factor 3a (E2F3a). The binding of CREBBP to downstream gene caspase 8 associated protein 2 (CASP8AP2) promoters was assessed using a chromatin immunoprecipitation assay, and mRNA expression levels were detected via reverse transcription-quantitative PCR. Western blot analysis was performed to detect protein expression of CREBBP, E2F3a and CASP8AP2. Downregulation of CREBBP increased the IC50 value of daunorubicin; however, no significant affects were observed on the IC50 values of vincristine and L-asparaginase. Furthermore, downregulation of CREBBP notably inhibited leukemia cell proliferation, accumulated cells in the G0/G1 phase and decreased cell proportions in the S and G2/M phases. Co-IP analysis demonstrated that CREBBP interacted with E2F3a, a transcription factor involved in G1/S transition. Immunofluorescence confocal microscopy indicated co-localization of CREBBP and E2F3a at the cell nucleus. Furthermore, E2F3a protein expression decreased in CREBBP RNA interference treated Jurkat and Reh cells. CASP8AP2, a target gene of E2F3a, was also identified to be a downstream gene of CREBBP. In addition, decreased IC50 value and cell proportions in the G0/G1 phase, accelerated cell proliferation and upregulated E2F3a and CASP8AP2 expression were exhibited in CREBBP overexpressed cells. Taken together, the results of the present study suggested that CREBBP downregulation affects proliferation and cell cycle progression in leukemia cells, potentially via the interaction and regulation of E2F3a, resulting in chemotherapy resistance. Thus, targeting CREBBP may be a therapeutic strategy for treating pediatric patients with ALL.

Abstract
This study explored an integrated framework to assess the effectiveness of adaptation measures on the water productivity (WP) of the agricultural water management (AWM) system in the Huai river basin of China considering climate change impact. The adaptation measures include optimization of cropping pattern (OCP) and upgradation of irrigation techniques (UIT). The delta change method was used to downscale the climate variables from RCP4.5 and RCP8.5 of general circulation models (GCMs) during 2021-2050, the water footprint theory was used to estimate the spatial distribution of blue water to calculate the WP, and the nonlinear optimization model was used to seek optimal cropping pattern aiming at maximizing the system's WP. The changes in WP due to climate change and adaptation measures (e.g. combinations of OCP and UIT) were compared. Results indicated that WP under RCP4.5 and RCP8.5 would be 4.56% and 6.51% lower than those under the benchmark scenario, respectively. The mitigation rates to the negative impact of climate change on WP under RCP4.5 and RCP8.5 would be (1) 3.05% and 3.37% for the combination of spay irrigation technique and OCP, and (2) 4.34% and 4.59% for the combination of drip irrigation technique and OCP, respectively. It was revealed that the combination of drip irrigation and cropping pattern optimization could largely offset the adverse effect from climate change on WP under RCP4.5. Under such a scenario, the total plant areas of wheat and maize would reduce over the basin and so would the net export of crops in the basin; this would lead to a decrease in the crop trade benefit of 7.07 × 109 $ and a relief of 7.50 × 109 m3 of blue water loss. This study results could offer strategic decision support for long-term sustainable AWM of Huai river basin in a changing environment.

Abstract
The extended line defect of graphene is an extraordinary candidate in valleytronics while the high valley polarization can only occur for electrons with high incidence angles which brings about tremendous challenges to experimental realization. In this paper, we propose a novel quantum mechanism to filter one conical valley state in the line defect of graphene by applying a local magnetic field. It is found that due to the movement of the Dirac points, the transmission profiles of the two valleys are shifted along the injection-angle axis at the same pace, resulting in the peak transmission of one valley state being reduced drastically while remaining unaffected for the other valley state, which induces nearly perfect valley polarization. The valley polarization effect can occur for all the incident angle and plays a key role in graphene valleytronics.

Abstract
Obesity is a growing chronic health problem worldwide. Studies about acupuncture for obesity treatment are many. But there are some doubts about the effectiveness of acupuncture versus sham acupuncture in treating obesity due to its lack of medical evidence. Therefore, the aim of this study is to assess the efficacy of acupuncture for obesity treatment and provide clinic evidence. Four English databases (PubMed, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials) and four Chinese databases (China National Knowledge Infrastructure, Chinese BioMedical Database, Chinese Scientific Journal Database and Wan-Fang Data) were searched from their receptions to August 2019. Randomized controlled trials (RCTs) using the comparison between acupuncture and sham acupuncture to treat simple obesity were included. The primary outcome of body mass index (BMI) would be used to measure the effect of acupuncture on obesity. According to the trial data extraction form based on the Cochrane Handbook, two reviewers separately extracted the data. Risk of bias of the RCTs was assessed by the Cochrane Risk of Bias Tool. The study included 8 RCTs with 403 patients. When compared with sham acupuncture, acupuncture showed obviously effect in BMI reduction (MD=1.0kg/m2, 95% CI=0.6 to 1.4, P<0.001). There was also significant reduction in body weight (MD=1.85kg, 95%CI=0.82 to 2.88, p<0.001), WC (MD=0.97cm, 95%CI=0.24 to 1.71, p=0.01) and body fat mass percentage (MD=1.01, 95%CI=0.25 to 1.77, p<0.05). However, WHR (MD=0.01, 95%CI=0 to 0.03, p>0.05) was not statistically and significantly different between the acupuncture and control groups. Adverse effects were reported in 3 studies. The review suggests that acupuncture is an effective therapy for simple obesity rather than a placebo effect. This potential benefit needs to be further evaluated by longer-term and more rigorous RCTs.

Abstract
AIM To investigate the clinical value of supplemental parenteral nutrition (SPN) in critically ill patients.
METHODS The clinical data of 108 critically ill patients hospitalized at our hospital from June 2014 to June 2016 were analyzed retrospectively. According to the method of nutrition used, the patients were divided into an enteral nutrition (EN) group (control group) and an EN combined with SPN group (observation group). The clinical effects were compared between the two groups.
RESULTS After 1 wk of SPN, serum albumin, prealbumin and hemoglobin were significantly higher in the observation group than in the control group (P < 0.05). The upper arm circumference between the two groups had no significant differences (P > 0.05). The incidence of infection and hospitalization time in the observation group were significantly lower than those of the control group (P < 0.05). The mortality of two groups was not statistically different (P > 0.05).
CONCLUSION SPN can effectively improve the nutritional status of critically ill patients, reduce the incidence of infection, and shorten the length of hospital stay.

Abstract
OBJECTIVE To explore the effects of TBLR1-RARα on the differentiation induction of leukemia cell line K562 cells into erythroid lineage and to investigate its related mechanisms. METHODS Tet-Off inducible system was used to construct the conditional expression vector of TBLR1-RARα fusion gene by cloning the TBLR1-RARα fragment into lentivirus vector pLVX-Tight-Puro, the expression of TBLR1-RARα fusion gene was induced by doxycycline (Dox). Then, K562 cells were transfected with lentivirus pLVX-Tight-Puro-TBLR1-RARα-flag, and the expression of fusion proteins was verified by Western blot. After treatment of K562 with all-trans retinoid acid (ATRA), real time RT-PCR was performed to test the expression of erythroid differentiation-related CD71 and α, ε, γ-globins gene. Flow cytometry was used also to analyze the expression of erythroid differentiation markers CD71 and CD235a. Benzidine staining was used to detect the production of hemoglobin in K562 cells. RESULTS qRT-RCR showed that ATRA could increase the expression level of CD71 and α, ε, γ-globin genes when TBLR1-RARα was expressed. After treatment of ATRA, the proportion of CD71(+) cells detected by the flow cytometry also increased. Benzidine staining showed that ATRA could induce hemoglobin production in K562 cells with TBLR1-RARα fusion gene expression. CONCLUSION The expression of TBLR1-RARα fusion gene contribute to ATRA-inducing differentiation of K562 cells into erythroid lineage.

Abstract
MicroRNAs (miRNAs) control gene expression through both translational repression and degradation of target messenger RNAs (mRNAs). However, the interplay between these processes and the precise molecular mechanisms involved remain unclear. Here, we show that translational inhibition is the primary event required for mRNA degradation. Translational inhibition depends on miRNAs impairing the function of the eIF4F initiation complex. We define the RNA helicase eIF4A2 as the key factor of eIF4F through which miRNAs function. We uncover a correlation between the presence of miRNA target sites in the 3' untranslated region (3'UTR) of mRNAs and secondary structure in the 5'UTR and show that mRNAs with unstructured 5'UTRs are refractory to miRNA repression. These data support a linear model for miRNA-mediated gene regulation in which translational repression via eIF4A2 is required first, followed by mRNA destabilization.

Abstract
We demonstrate experimentally negative refraction by a photonic crystal prism and imaging of a point source by a photonic crystal slab at 1.5 microm wavelength. The photonic crystal structures were nanofabricated in a InGaAsP/InP heterostructure platform, and optical characterization was performed using a near-field scanning optical microscope. By designing a suitable lens surface termination, an image spot size of 0.12lambda2 was achieved, demonstrating superlens imaging with subwavelength resolution well below Abbe's diffraction limit (0.5lambda2).

Abstract
Refraction at a smooth interface is accompanied by momentum transfer normal to the interface. We show that corrugating an initially smooth, totally reflecting, non-metallic interface provides a momentum kick parallel to the surface, which can be used to refract light negatively or positively. This new mechanism of negative refraction is demonstrated by visible light and microwave experiments on grisms (grating-prisms). Single-beam all-angle-negative-refraction is achieved by incorporating a surface grating on a flat multilayered material. This negative refraction mechanism is used to create a new optical device, a grating lens. A planoconcave grating lens is demonstrated to focus plane microwaves to a point image. These results show that customized surface engineering can be used to achieve negative refraction even though the bulk material has positive refractive index. The surface periodicity provides a tunable parameter to control beam propagation leading to novel optical and microwave devices.

Abstract
We establish a duality between the quantum wave vector spectrum and the eigenmodes of the classical Liouvillian dynamics for integrable billiards. Signatures of the classical eigenmodes appear as peaks in the correlation function of the quantum wave vector spectrum. A semiclassical derivation and numerical calculations are presented in support of the results. These classical eigenmodes can be observed in physical experiments through the autocorrelation of the transmission coefficient of waves in quantum billiards. Exact classical trace formulas of the resolvent are derived for the rectangle, equilateral triangle, and circle billiards. We also establish a correspondence between the classical periodic orbit length spectrum and the quantum spectrum for integrable polygonal billiards.

Abstract
An Ising model on the kagome lattice with super-exchange interactions is solved exactly under the presence of a nonzero external magnetic field. The model generalizes the super-exchange model introduced by Fisher in 1960 and is analyzed in light of a free-fermion model. We deduce the critical condition and present detailed analyses of its thermodynamic and magnetic properties. The system is found to exhibit a second-order transition with logarithmic singularities at criticality.

Abstract
We demonstrate the negative refraction of microwaves in a metallic photonic crystal prism. The spectral response of the photonic crystal prism, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical simulations. The validity of Snell's law with a negative refractive index is confirmed experimentally and theoretically. The negative refraction observed corresponds to left-handed electromagnetism that arises due to the dispersion characteristics of waves in a periodic medium. This mechanism for negative refraction is different from that in metamaterials.

Abstract
We present a conjecture relating the density of quantum resonances for an open chaotic system to the fractal dimension of the associated classical repeller. Mathematical arguments justifying this conjecture are discussed. Numerical evidence based on computation of resonances of systems of n disks on a plane are presented supporting this conjecture. The result generalizes the Weyl law for the density of states of a closed system to chaotic open systems.

Abstract
To study the effectiveness of a lipoxygenase inhibitor, nordihydroguaiaretic acid (NDGA), in the reduction of primary nonfunction, an insufficient number of syngeneic islets were transplanted underneath the renal capsule with NDGA administered daily for 4 weeks. After transplantation of the 150 islets, the decrement of blood glucose levels was significantly faster in the mice that had received NDGA than in the mice that had received no drug at all or dimethyl sulfoxide (DMSO) (p < 0.005, p < 0.05). The mean duration of temporary posttransplant hyperglycemia was 22.3 +/- 3.2 (n = 10), 35.9 +/- 2.3 (n = 14), and 33.7 +/- 4.1 (n = 6) days for the respective groups. The diabetic mice that received 300 islets had their blood glucose levels decrease faster than those that received 150 islets (19.7 +/- 1.6 vs. 35.9 +/- 2.3 days, n = 14. p < 0.0001). There was no significant difference in the blood glucose reducing effect between the mice that received 150 islets with NDGA and the mice that received 300 islets [22.3 +/- 3.2 (n = 10) vs. 19.7 +/- 1.6 (n = 14) days, p > 0.05]. The insulin content of the graft from the mice treated with 150 islets and NDGA (3.02 +/- 0.24 microg, n = 4) was higher than that from the mice that received 150 islets but no treatment (1.10 +/- 0.26 microg, n = 15, p < 0.005) or that had been treated with DMSO (1.21 +/- 0.30 microg, n = 4, p <0.05). The insulin content of the pancreas remnant had no significant differences among the three groups. The net glucose-stimulated insulin secretion was 0.82 +/- 0.14 vs. 0.20 +/- 0.10 microIU/islet x 60 min (n = 8, p < 0.005) and 0.59 +/- 0.08 vs. 0.04 +/- 0.02 microIU/islet x 60 min (n = 8, p < 0.0001) for islets cultured without NDGA vs. with NDGA at 1 and 2 weeks, respectively. However, the insulin content of the cultured islets was similar between the two groups for up to 2 weeks of incubation (at 1 week: 0.71 +/- 0.01 vs. 0.67 +/- 0.04 ng/islet, n = 8, p > 0.05; at 2 weeks: 0.71 +/- 0.02 vs. 0.80 +/- 0.07 ng/islet, n = 8, p > 0.05). Serum leukotriene B4 (LTB4) concentrations before and between the fifth and seventh days after transplantation were determined. For diabetic mice that received 150 islets, serum LTB4 levels were 25,835 +/- 3,335 and 27,631 +/- 3,136 pg/ml (n = 4, p > 0.05). For diabetic mice that received 150 islets and NDGA, the corresponding figures were 22,401 +/- 2,706 pg/ml and 27,530 +/- 2,190 pg/ml (n = 8, p > 0.05). The graft histology revealed viable islet cells and networks of close vascular structures around the islets and did not reveal microscopic differences among the samples of all four groups. In conclusion, our data revealed that daily administration of NDGA for 4 weeks enhanced isoislet engraftment and preserved three times more mass of the islet beta cells in the isografts. This result indicates that NDGA reduces primary nonfunction of islet syngeneic grafts in diabetic mice.

Abstract
Closed-form expressions are obtained for the partition function of the Ising model on an MxN simple-quartic lattice embedded on a Möbius strip and a Klein bottle. The solutions all lead to the same bulk free energy, but for finite M and N the expressions are different depending on whether the strip width M is odd or even. Finite-size corrections at criticality are analyzed and compared with those under cylindrical and toroidal boundary conditions. Our results are consistent with the conformal field prediction of a central charge c=1/2, provided that the twisted Möbius boundary condition is regarded as a free or fixed boundary.

Abstract
BACKGROUND Familial hypercholesterolemia is associated with a very high risk of premature coronary heart disease. In order to identify cases of familial hypercholesterolemia in Taiwan, we screened the hyperlipidemic patients in our metabolic clinics. METHODS Hyperlipidemic patients were screened in the metabolic outpatient department and the cases which fulfilled the clinical criteria of definitive or possible familial hypercholesterolemia were further analyzed. Their clinical characteristics, including age, gender, physical findings, past history of coronary heart disease or cerebrovascular accident (CVA), family history, and lipid profiles before and after medical treatment, were reviewed. RESULTS Eight women and 3 men fulfilled the diagnostic criteria. The mean age at diagnosis was 51.1 +/- 11.9 years old. Tendon xanthomas were found in 5 patients with definitive familial hypercholesterolemia. Coronary heart disease was confirmed in one patient and old CVA was noted in another 2 patients. The mean total cholesterol level was 390.3 +/- 88.9 mg/dl and the mean low density lipoprotein-cholesterol (LDL-cholesterol) level was 309.6 +/- 89.9 mg/dl before treatment. After a mean treatment duration of 45.2 months, the mean total cholesterol level and LDL-cholesterol level were 326.8 +/- 87.8 mg/dl and 249.1 +/- 91.1 mg/dl, respectively. CONCLUSION Clinically diagnosed familial hypercholesterolemia indeed exists in Taiwan. As compared to other reports, the mean age at diagnosis in our series was older and the majority of patients were women. Most patients were not vigorously treated and the family members were not thoroughly screened. Adequate treatment of patients with familial hypercholesterolemia in clinical practice and screening their family members are crucial in preventing new or recurrent coronary heart disease.

Abstract
Radioactive iodine (131I) has been found to be more sensitive and more specific than thallium-201 for the detection of distant metastases and thyroid remnants in the neck in cases of well-differentiated thyroid carcinoma. 201Tl has been deemed particularly useful in localizing metastases or recurrence in patients with a negative 131I scan and abnormal levels of serum thyroglobulin (Tg). This study aimed to: (1) determine the value of 201Tl imaging in localizing metastases or recurrence in patients with well-differentiated thyroid carcinoma, and (2) evaluate the false-positive and false-negative results of 131I and 201Tl scintigraphy. Sixty-two thyroid remnant ablated patients who underwent simultaneous postoperative 201Tl and 131I scans and and serum Tg determinations were evaluated. Fifty patients had papillary thyroid carcinomas and 12 had follicular thyroid carcinomas. 201Tl imaging was performed before the 131I studies. Of the 62 patients who underwent 201Tl imaging studies, 24 were found to have positive results, with local recurrence or distant metastases. Patients with positive results in the 201Tl imaging studies tended to be older, were mor often male, had higher Tg levels and had a higher recurrence rate. Of these 24 patients, ten had negative diagnostic or therapeutic 131I scans. Concurrently, serum Tg levels were less than 5 ng/ml in five of these ten patients. Three patients were deemed false positive by 201Tl scans; one had a parotid tumour, one a periodontal abscess and one lung metastasis. Among the 38 patients with negative 201Tl scans, 11 had positive findings on 131I scans. Three had distant metastases: two with lung metastases and one with bone metastases. Patients with false-positive results on 131I scans included those with biliary tract stones, ovarian cysts, and breast secretion. Of the 27 patients with negative 201Tl and 131I scans, 15 had elevated serum Tg levels. Among these, local recurrence followed by lung metastases was manifested in a 49-year-old male with papillary thyroid carcinoma. In conclusion, both 131I and 201Tl scans are useful in the detection of recurrence or distant metastasis of well differentiated thyroid cancers. 201Tl scan could in particular be used in patients with a negative 131I scan in conjunction with an elevated Tg level.

Abstract
Anaplastic thyroid carcinoma is one of the most lethal neoplasms, with poor prognosis being reported by most authors. The benefits of surgery for most cases of advanced disease remain controversial. In this study we asked the following question: Does surgical intervention alter outcomes for patients with advanced anaplastic thyroid carcinoma? Forty-six patients with advanced anaplastic thyroid carcinoma were analyzed. There were 20 patients with advanced localized disease (group 1), 15 of whom received surgery. Of the other 26 patients with evidence of distant metastases (group 2), 13 received surgery. For group 1 patients, the mean survival was 12.8 months versus 8.6 months in the surgical and nonsurgical subgroups (p = 0.46). For group 2 patients, the mean survival was 3.5 months versus 2.8 months in the surgical and nonsurgical subgroups (p = 0.72). These data suggest that surgery does not improve survival for patients with advanced anaplastic thyroid carcinoma. In conclusion, the mean survival showed no significant differences between surgical and nonsurgical patients (p = 0.43). This study suggests that surgical resection does not improve the survival of patients with advanced anaplastic thyroid carcinoma.

Abstract
We retrospectively assessed the factors that may contribute to fecal soiling after surgery for Hirschsprung's disease. Fifty-eight patients underwent surgery for Hirschsprung's disease and returned for follow up. The patients were divided into two groups based on the presence or absence of fecal soiling. The postoperative period, level of bowel pulled through, stool frequency, stool character, presence or absence of anorectal surgical complications, and manometric findings of the two groups were compared. Forty-three patients (40 boys, 3 girls, mean age 9.5 yr) had soiling and 15 (10 boys, 5 girls, mean age 10.2 yr) did not. Patients with soiling had significantly higher rates of anorectal surgical complications (60% vs 7%), abnormal stool character (75% vs 7%), stool frequency greater than three times per day (63% vs 20%), absence of rectoanal inhibitory reflex (33% vs 2%), and narrow anorectal pressure gradient (60% vs 13%) than those without. The results of manometric study suggested that a damaged internal sphincter or irritable neorectum might have contributed to fecal soiling. In conclusion, although anorectal surgical complications might result in both irritable neorectum and damaged internal sphincter, their effect on the neorectum (significantly increased rate of high resting rectal pressure) seemed to outweigh that on the internal sphincter. A competent anal sphincter and a less irritable neorectum after operation may therefore lower the likelihood of fecal soiling.

Abstract
Fifty-eight patients with anorectal malformations were closely followed up for postoperative anorectal function. Constipation was noted shortly after anorectoplasty in 10 of 28 low anomalies (35.7%) treated with limited sagittal anorectoplasty (LSARP), in 18 of 25 high or intermediate anomalies (72.0%) treated with posterior sagittal anorectoplasty (PSARP), but in none of 5 high or intermediate anomalies treated with Rehbein's mucosa-stripping endorectal pull-through and anterior sagittal perineal anorectoplasty (R-ASAP). The constipation resolved mostly within 1-2 years after repair under conservative management, but persisted beyond 2 years after repair in 3/25 children with LSARP and 10/25 with PSARP. Anal soiling was noted in 1/23 (4.3%) LSARP and 6/22 (27.3%) PSARP patients, but normal anorectal function was attained in 20/23 LSARP (86.9%) and 11/12 PSARP patients (50.0%) by the time of toilet training. Manometric studies disclosed that the resting rectal pressure (RRP) was lower and the anorectal pressure gradient (ARPG) higher in the constipated than the non-constipated children, while the RRP was higher and the ARPG lower in the soiled than the non-soiled patients. The ARPG after R-ASPA was close to that of non-constipated and in between that of the constipated and soiled patients. The rectoanal sphincter inhibitory reflex was not related to defecation status or surgical procedures, but showed a tendency toward positive conversion with time or after exclusion of esctatic terminal bowel in the severely constipated. It is concluded that anorectal function in patients with repaired imperforate anus seems to be more affected by the extent of endopelvic dissection than by preservation of the terminal bowel or sphincter muscles.

Abstract
A 9-year-old girl was discovered to have had a huge retroperitoneal mass causing moderate hydronephrosis and anterior displacement of the right kidney and which was found on a renal ultrasonographic examination. A series of examinations including (1)IVP, (2) abdominal computed tomography, (3) MRI and(4) incisional biopsy revealed a giant dumb-bell shaped retroperitoneal ganglioneuroma with intraspinal involvement. Secondary scoliosis was also noticed. We successfully resected the huge ganglioneuroma of the right retroperitoneum in a two stage procedure: her postoperative course was uneventful.

Abstract
BACKGROUND Heavy alcohol intake (> 45 g daily) might be a cause of diabetes. The short-term risks of heavy alcohol intake include ketoacidosis, glucose intolerance and pancreatitis. Alcoholic ketoacidosis (AKA) in combination with hyperglycemia mimics diabetic ketoacidosis (DKA). We described the characteristics of heavy drinkers with ketoacidosis and hyperglycemia but without a prior history of diabetes. METHODS Twelve habitually heavy drinkers who had not been previously diagnosed as diabetes were identified by reviewing the records of diabetic patients admitted to Chang Gung Memorial Hospital from 1989 to 1992. All of them met DKA criteria. RESULTS Elevated glycohemoglobulin (HbAlc) level is an indicator for the diagnosis of diabetes. Among these 12 patients, 10 had elevated levels of HbAlc and 2 had normal HbAlc levels. Of these 2 patients, 1 had an elevated level of HbAlc 6 months later; the other who was a female who after observation, had normal levels of HbAlc and glucose for the follow-up of two years. CONCLUSION We found that most heavy drinkers with both ketoacidosis and hyperglycemia also had diabetes as indicated by high levels of HbAlc. The only female patient had normal HbAlc and was diagnosed as AKA rather than DKA.

Abstract
Splenic cysts were found, incidentally, in eight children during the past nine years (1987-1995) in Taipei Municipal Women's and Children's Hospital. Five of the children were boys and three were girls. The age at diagnosis ranged from 8 to 15 years. Evidence of possible splenic cyst development was found initially by ultrasonography; six patients received further evaluation with computerized tomography (CT); one patient received radionuclide scanning. The cysts ranged from 2 cm to 14 cm in diameter. Four of the patients received surgical treatment (three partial splenectomy and one total splenectomy) because of huge splenic cysts (diameter > 10 cm). Subsequent pathological examination revealed that all cysts had epithelial cell lining in the cyst wall, meaning they were all congenital in origin. The remaining four cases were followed up at the Out-patient Clinic here. All cases had a benign clinical course.

Abstract
Lymphangioma confined exclusively to the mediastinum occurs rarely in patients under 2 years of age. A 17-month-old girl presented with recurrent respiratory symptoms and signs. Chest radiographs taken at 9 and 17 months of age showed a large mediastinal mass, which had increased in size during the interval. Sonography revealed the mass to be cystic and multiloculated. Magnetic resonance imaging demonstrated a heterogeneous mass lying in the anterior and superior mediastinum and enveloping the great vessels. The child underwent a left thoracotomy and the tumor was almost completely removed. The pathologic diagnosis was cavernous lymphangioma. The postoperative course was uneventful. Lymphangioma, though rare, should be considered in the differential list of mediastinal tumors and cysts in infants.

Abstract
A seven-year-old boy with a retrovesical diverticulum and ipsilateral renal dysplasia is reported. He had had a history of frequent urination and dysuria for four years. According to sonography, the volume of bladder diverticulum obviously changed during urination. The diverticulum presented as a temporary large reservoir of the bladder. In this case, serial ultrasonic changes assisted understanding of the role of the diverticulum during urination.

Abstract
A girl with unilateral renal hypoplasia, ipsilateral Gartner's duct cyst and ipsilateral imperforate hemivagina is reported. She had a history of urinary drib-bling since early childhood. Recently, a foul bloody vaginal discharge was noted. Diagnosis was highly suspected on pelvic sonography, computerized tomography and magnetic resonance imaging, and was confirmed by punctures in the genitourinary tract with contrast study during surgery. This anomaly is extremely rare. Although three patients with similar conditions have been previously reported, different clinical presentations were noted in this patient.
