Abstract
To investigate the serological and genetic characteristics of para-Bombay patients in a hospital in Hunan Province. A retrospective analysis was conducted on the blood type results of 175 439 hospitalized patients born in Hunan Province from the Third Xiangya Hospital, Central South University from 2016 to 2021. Phenotypes of ABO blood group was analyzed by blood group serology, and molecular biological methods were used to analyze the genotype, including ABO genotyping by polymerase chain reaction-sequence specific primers (PCR-SSP) and fucosyltransferase 1 (FUT1) and fucosyltransferase 2 (FUT2) gene sequencing. The results showed that 3 cases of Ah and 1 case of Bh were detected. FUT1 sequencing showed that there were 2 cases of h3h3, 1 case of h1h1 and 1 case of h302h1, of which h302 (c.302C>T) was the first discovered mutation. FUT2 sequencing revealed that 4 cases were all Se357Se357. The pedigree study showed that the inheritance of para-Bombay blood group was consistent with autosomal dominant inheritance. In conclusion, the FUT1 gene mutations leading to para-Bombay blood group mainly include h3, h1 and h302, of which h3 mutation is the most common.

Abstract
Improved durability, enhanced interfacial stability, and room temperature applicability are desirable properties for all-solid-state lithium metal batteries (ASSLMBs), yet these desired properties are rarely achieved simultaneously. Here, in this work, it is noticed that the huge resistance at Li metal/electrolyte interface dominantly impeded the normal cycling of ASSLMBs especially at around room temperature (<30 °C). Accordingly, a supramolecular polymer ion conductor (SPC) with "weak solvation" of Li+ was prepared. Benefiting from the halogen-bonding interaction between the electron-deficient iodine atom (on 1,4-diiodotetrafluorobenzene) and electron-rich oxygen atoms (on ethylene oxide), the O-Li+ coordination was significantly weakened. Therefore, the SPC achieves rapid Li+ transport with high Li+ transference number, and importantly, derives a unique Li2 O-rich SEI with low interfacial resistance on lithium metal surface, therefore enabling stable cycling of ASSLMBs even down to 10 °C. This work is a new exploration of halogen-bonding chemistry in solid polymer electrolyte and highlights the importance of "weak solvation" of Li+ in the solid-state electrolyte for room temperature ASSLMBs.

Abstract
Objective: To explore the correlation between polycyclic aromatic hydrocarbons (PAHs) component phenanthrene and clinical indicators in patients on continuous ambulatory peritoneal dialysis (CAPD). Methods: A total of 22 patients who underwent peritoneal dialysis catheterization and regular dialysis in the First Affiliated Hospital of Zhengzhou University from June to August 2018 were selected. Meanwhile, 18 healthy adults who underwent physical examination were also selected as the control group. Fasting blood samples were taken to detect the concentration of PAHs components for comparison, and the correlation between PAHs components and clinical indicators was further analyzed. Results: There were 22 cases in CAPD group (13 males and 9 females), and aged (45±13) years, while there were 18 cases in control group (6 males and 12 females), and aged (41±13) years. The concentration of blood phenanthrene (PHE) was the highest in CAPD group [0.449 (0.254, 0.581) mg/L], and it was only lower than acenaphthene in the control group [0.081 (0.050, 0.444) mg/L], with a statistically significant difference between the two groups (P=0.008). The analysis of PHE and clinical indicators showed that the concentration of PHE in CAPD patients was negatively correlated with weekly urea clearance index (Kt/V), weekly creatinine clearance (Ccr) and leukocyte level, but positively correlated with triglyceride level (r=-0.743, -0.749, -0.655 and 0.610, respectively, all P<0.05). Simple linear regression analysis demonstrated that for every 0.1 mg/L increase in PHE concentration, weekly Kt/V, weekly Ccr and white blood cell count decreased by 0.226, 3.050 L/1.73 m2 and 0.512×109/L, respectively, but triglyceride level increased by 0.152 mmol/L (all P<0.05). Multiple linear regression analysis revealed that the blood PHE concentration of CAPD patients was negatively correlated with weekly Kt/V and Ccr levels (t=-2.402 and -2.368, respectively, both P<0.05). All CAPD patients were followed up for 3 years, during which 8 patients (36.4%) withdrew from peritoneal dialysis due to technical failure, and the baseline PHE concentration was higher than that of patients who did not quit peritoneal dialysis [0.572 (0.416, 0.662) vs 0.268 (0.120, 0.475) mg/L, P=0.003]. Eight patients (36.4%) had cardiovascular events, and the baseline blood PHE concentration was higher than that of patients without cardiovascular events [0.542 (0.389, 0.741) vs 0.373 (0.157, 0.545) mg/L, P=0.045]. Conclusion: PHE correlates with clinical indicators of CAPD patients, including Kt/v, Ccr, leukocyte and triglyceride.

Abstract
Plastic deformation in crystalline materials occurs through dislocation slip and strengthening is achieved with obstacles that hinder the motion of dislocations. At relatively low temperatures, dislocations bypass the particles by Orowan looping, particle shearing, cross-slip or a combination of these mechanisms. At elevated temperatures, atomic diffusivity becomes appreciable, so that dislocations can bypass the particles by climb processes. Climb plays a crucial role in the long-term durability or creep resistance of many structural materials, particularly under extreme conditions of load, temperature and radiation. Here we systematically examine dislocation-particle interaction mechanisms. The analysis is based on three-dimensional discrete dislocation dynamics simulations incorporating impenetrable particles, elastic interactions, dislocation self-climb, cross-slip and glide. The core diffusion dominated dislocation self-climb process is modelled based on a variational principle for the evolution of microstructures, and is coupled with dislocation glide and cross-slip by an adaptive time-stepping scheme to bridge the time scale separation. The stress field caused by particles is implemented based on the particle-matrix mismatch. This model is helpful for understanding the fundamental particle bypass mechanisms and clarifying the effects of dislocation glide, climb and cross-slip on creep deformation.

According to original fracture displacement direction, patients were divided into extension fracture(Colles) group and flexion fracture (Smith) group. In Colles fracture group, there were 24 males and 44 females aged from 20 to 79 years old with an average of (59.0±13.4) years old;according to AO classification, 9 patients of type A2, 13 patients of type A3, 16 patientsof type C1, 17 patients of type C2 and 13 patients of type C3;the time from injury to operation ranged from 2 to 9 days with an average of (3.9±0.8) days. In Smith fracture group, there were 15 males and 20 females, aged from 27 to 87 years old with an average of (60.1±15.3) years old;according to AO classification, 4 patienst of A2, 7 patients of A3, 14 patients of C1, 5 patients of C2 and 5 patients of C3;the time from injury to operation ranged from 2 to 6 days with an average of (4.1±0.9) days. Operation time, fracture healing time and postoperative complications were recorded between two groups. Disabilities of arm, shoulder and hand (DASH) score at 6 and 8 weeks, 6 and 8 months were used to evaluate functional recovery of affected limbs during each follow up. Volar tilt, radial inclination and radius height were measured at 8 months after operation. Mayo score was measured at 8 months after operation to evaluate recovery of limb function. RESULTS All patients were followed up for 8 to 30 months with an average of (14.8±4.3) months, and no difference in follow up between two groups (P> 0.05). There were no statistical differences in operation time, fracture healing time and postoperative complications between two groups(P>0.05). DASH score at 6 and 12 weeks in Colles fracture group were (37.24±5.08) and (19.68±4.55), while in Smith fracture group were (39.05±4.79) and (23.44±4.21);Colles fracture group was better than that of Smith fracture group (P<0.001);while there were no differences in DASH score at 6 and 8 months between two groups (P>0.05). Volar tilt of Smith fracture group (11.1±3.1)° was better than that of Colles fracture group (8.6±4.1) °, and there were no significant difference in radial inclination and radius height between two groups(P>0.05). Also there was no significant difference in Mayo score between two group(P>0.05). CONCLUSION Patients with Colles fracture and Smith fracture could receive good reduction and fixation through volar locking plate. The radiographic parameters of both groups recovered satisfactorily after operation. Recovery of volar tilt of Smith fracture group is better than that of Colles fracture group, and early recovery function of Colles fracture group is better than that of Smith group, but there is no significant difference in long-term wrist joint function and incidence of postoperative complications between two groups.

Abstract
Objective: To explore the clinical features and prognosis of gastric mucosa-associated lymphoid tissue lymphoma. Methods: The data of patients with gastric mucosa-associated lymphoid tissue lymphoma diagnosed and treated at Peking University Cancer Hospital from 2000 to 2019 were collected, and their clinical characteristics, treatment options and effects, and prognosis were retrospectively analyzed. Results: The median age of 68 patients was 56 years old, and the ratio of men to women was 0.6∶1.0. Early patients accounted for about 76% (52/68). The most commonly used treatment is Helicobacter pylori eradication, followed by radiotherapy and chemotherapy. The total effective rate is 94%, of which the complete remission rate is 72%. With a median follow-up of 44 months, the 5-year progression-free survival (PFS) rate was 73%, and the overall survival (OS) rate was 83%. Prognostic factor analysis showed that albumin level (P=0.011) and international prognostic index (IPI)(P=0.017) are independent prognostic indicators of PFS, The 5-year PFS rate of patients with normal and reduced albumin was 77% and 50%, respectively, and the 5-year PFS rate of patients with IPI score<2 points and IPI ≥ 2 points was 80% and 48%, respectively. Lactate dehydrogenase (LDH) (P=0.016) and albumin level (P=0.025) are independent prognostic indicators of OS, and the 5-year OS rates of patients with normal and elevated LDH were 87% and 67%, respectively. The 5-year OS rates of patients with normal albumin and reduced were 92% and 73%, respectively. Conclusions: Gastric mucosa-associated lymphoid tissue lymphoma is sensitive to treatment and has a good prognosis. The patient's albumin and lactate dehydrogenase levels are independent prognostic indicators.

Abstract
Objective To assess the changes in alignment of ipsilateral knee joint after total hip arthroplasty (THA) for patients with developmental dysplasia of the hip (DDH). Methods Thirty‐four patients with DDH (38 hips) who underwent THA between February and December 2008 were included in the study: 4 men and 30 women with a mean age of 56.2 years. According to Crowe classification, 11 patients were grade I, 12 were grade II, 9 were grade III, and 6 were grade IV. Computed tomography scans were performed from the anterior superior iliac spine to the tibial tubercle before surgery and at last follow‐up. Femoral anteversion angle, leg lengthening, and knee alignment, including patellar tilt angle, lateral patellar displacement, and tibiofemoral rotation angle, were measured on computed tomography scans, and their relationships were analyzed. Results The mean follow‐up period was 51.5 months (range, 39–70 months). There were no intraoperative fractures, and no infections occurred during the follow‐up period. One patient developed deep venous thrombosis and another suffered from femoral nerve palsy. The mean preoperative Harris Hip Score was 48.9 ± 7.5 and improved to 91.2 ± 8.3 by the last follow‐up (P < 0.001). There was no sign of prosthetic loosening in all hips. Postoperatively, mean leg lengthening was 26.08 ± 21.81 mm (P < 0.001), femoral anteversion decreased 9.03° ± 12.80° (P < 0.001), and patellar tilt, lateral patellar displacement, and tibiofemoral rotation increased by 3.58° ± 4.96° (P < 0.001), 1.78 ± 3.36 mm (P = 0.002), and 2.56° ± 3.37° (P < 0.001), respectively. Postoperative increase in patellar tilt and lateral patellar displacement had significant linear relationships with the decrease in femoral anteversion (r = 0.621, P < 0.001 and r = 0.437, P = 0.0037, respectively). These results revealed that patellofemoral alignment would change more with the decrease in femoral anteversion. Postoperative increase in external rotation of the tibia had significant positive linear relationships with leg lengthening (r = 0.34, P = 0.037) and the decrease in femoral anteversion (r = 0.693, P < 0.001). These results revealed that the external rotation of the proximal tibia would increase with the leg lengthening or the decrease of femoral anteversion. Postoperative changes in patellar tilt and lateral patellar displacement had no significant linear relationships with leg lengthening (P = 0.795 and P = 0.082, respectively). Conclusions Total hip arthroplasty for DDH could induce changes in alignment of ipsilateral patellofemoral and tibiofemoral joints, with increases in patellar tilt and displacement, and increases in external rotation of the tibia. These secondary alterations still existed at medium‐term follow‐up after surgery, which should be considered during THA for patients with DDH. Extended follow‐up is necessary to evaluate long‐term changes in the knee joint.

The study aimed to determine the effects of methionine hydroxy analog chelate zinc on the tibia quality, mineral deposit, apparent retention of nutrients, and liver metallothionein (MT) expression level of aged laying hens. A total of 960 layers (Hy-Line Grey, 57 wk old) were randomly assigned into 4 groups, and each group had 8 replicates of 30 hens. During the first 2 wk, groups were fed a basal diet without extra zinc (Zn: 35.08 mg/kg). During the ensuing 14 wk, 4 levels of Zn (inorganic Zn: 80 mg/kg; organic Zn: 20, 40, 80 mg/kg) were added to the diet. The results indicated that both the Zn source and level did influence tibia strength and calcium (Ca) and Zn concentrations of tibia (P < 0.05), whereas there were no differences in the copper (Cu) and phosphorus (P) concentrations of the tibia and the tibia length (P > 0.05). Moreover, dietary supplementation with 40 or 80 mg/kg of organic Zn showed higher Zn and Ca concentrations in the tibia and higher tibia strength. The Cu concentration in the liver showed no difference among the 4 treatments, whereas the Zn concentration in the liver increased with the increasing Zn level. The apparent retention of P, iron (Fe), and manganese (Mn) was not affected by the Zn level or source (P > 0.05). However, the organic Zn group increased the apparent retention of Cu, Zn, Ca, crude protein (CP), and energy, and the group supplemented with 40 or 80 mg/kg of organic Zn obtained significant effects (P < 0.05). Moreover, dietary supplementation with 40 or 80 mg/kg organic Zn increased the MT mRNA expression of the liver at week 72, whereas 20 mg/kg of organic Zn decreased it (P < 0.05). In conclusion, this study suggested that an optimum dietary (40 mg/kg) organic Zn level plays a key role in promoting the apparent retention of minerals and nutrients, trace element deposit, and MT mRNA expression.

Abstract
Objective: To investigate whether the co-culture of Huh7.93 cells and peripheral blood mononucleated cells from chronic hepatitis B patients (cPBMCs) can simulate the replication features of hepatitis B virus (HBV) and immune function in chronic hepatitis B (CHB) patients, and to provide an in vitro cell co-culture system for the research on immune clearance in chronic HBV infection. Methods: Huh7.93 cells were cultured alone or co-cultured with peripheral blood mononucleated cells from healthy people who underwent physical examination (nPBMCs) or cPBMCs for 7 days. The CCK8 assay was performed to measure the proliferative activity of Huh7.93 cells, and quantitative real-time PCR and Southern blot were used to measure HBV replication in cPBMCs and co-cultured cells. The independent samples t-test was used for comparison between two groups. Results: When Huh7.93 cells were co-cultured with peripheral blood mononucleated cells (PBMCs) at a certain ratio, Huh7.93 cells had a high proliferative activity and good cell growth. HBV could not infect or replicate in cPBMCs. HBV DNA in the supernatant of Huh7.93 cells co-cultured with cPBMCs showed significant increases and significantly higher than that in the supernatant of Huh7.93 cells cultured alone on day 4 (6.01 ± 0.20 log10copies/ml vs 4.99 ± 0.08 log10copies/ml, P = 0.000) and day 7 (7.82 ± 0.24 log10copies/ml vs 6.96±0.09 log10copies/ml, P = 0.000). On day 7 of culture, the cell lysis buffer of Huh7.93 cells co-cultured with cPBMCs had a significant increase in the level of HBV replicative intermediate compared with that of Huh7.93 cells cultured alone. After HepG2.2.15 cells were co-cultured with cPBMCs, there was no significant increase in HBV replication. Conclusion: The co-culture of Huh7.93 cells and cPBMCs produces similar viral replication as human body infected with HBV and can well simulate the liver microenvironment and immune function in CHB patients, which provides a new method for the research on immune clearance in chronic HBV infection.

Abstract
Background Visceral adipose tissue is more metabolically active than other fat depots and is more closely associated with obesity-related diseases, such as cardiovascular disease and type 2 diabetes, than indicators of obesity, such as body mass index. Across various strategies to promote weight loss, including energy-reduced diet and exercise, variable effects on VAT compared to loss of total body fat have been reported. Methods To examine the effect of a behavioral weight loss intervention using portion-controlled prepackaged entrées on VAT, we examined data and measurements from overweight/obese men and women (N=183) who were assigned to a weight loss intervention and prescribed a reduced-energy diet with either portion-controlled prepackaged entrées or self-selected meals in a randomized clinical trial. VAT was estimated with dual-energy X-ray absorptiometry at baseline and study end (12 weeks). Results VAT loss was greater for the prepackaged entrees group (p=0.02), with an average loss of 29% compared to an average loss of 19% among participants consuming self-selected meals. VAT (mean [SEM]) was 1651 (71) g and 1546 (157) g at baseline and 1234 (59) g and 1278 (118) g at study end in the prepackaged entrees and self-selected meal groups, respectively. Greater VAT loss was associated with higher baseline weight and VAT, and greater weight loss, but not associated with age or physical activity. Conclusion Prescribing portion-controlled prepackaged entrees in a behavioral weight loss intervention promotes a reduction in VAT, which should promote improved metabolic profile and reduced cardiovascular disease risk.

Abstract
Tarantula venoms provide a model system for studying toxin selectivity, structure-activity relationships and molecular evolution of peptide toxins. Previous studies have identified a large number of peptide toxins in the venom of the Chinese bird spider Haplopelma hainanum, generally regarded as a highly venomous spider. However, the lack of available RNA-seq transcriptomic and genomic data is an obstacle to understanding its venom at the molecular level. In this study, we investigated the venom gland transcriptome of H. hainanum by RNA-seq, in the absence of an available genomic sequence. We identified 201 potential toxins among 57 181 de novo assembled transcripts, including knottins, Kunitz-type toxins, enzymes and other proteins. We systematically identified most of the knottins and Kunitz-type toxins, some of which showed strongly biased expression in the venom gland, including members of the huwentoxin-1, huwentoxin-2 and magi-1 families. We also discovered several novel potential toxins. These data demonstrate the high molecular and structural diversity in the venom toxins of H. hainanum. This study offers a useful strategy for exploring the complex components of spider venoms.

Abstract
Background: The properties of subchondral bone influence the integrity of articular cartilage in the pathogenesis of osteoarthritis (OA). However, the characteristics of subchondral bone alterations remain unresolved. The present study aimed to observe the dynamic alterations in the microarchitecture, mineralization, and mechanical properties of subchondral bone during the progression of OA. Methods: A medial meniscal tear (MMT) operation was performed in 128 adult Sprague Dawley rats to induce OA. At 2, 4, 8, and 12 weeks following the MMT operation, cartilage degeneration was evaluated using toluidine blue O staining, whereas changes in the microarchitecture indices and tissue mineral density (TMD), mineral-to-collagen ratio, and intrinsic mechanical properties of subchondral bone plates (BPs) and trabecular bones (Tbs) were measured using micro-computed tomography scanning, confocal Raman microspectroscopy and nanoindentation testing, respectively. Results: Cartilage degeneration occurred and worsened progressively from 2 to 12 weeks after OA induction. Microarchitecture analysis revealed that the subchondral bone shifted from bone resorption early (reduced trabecular BV/TV, trabecular number, connectivity density and trabecular thickness [Tb.Th], and increased trabecular spacing (Tb.Sp) at 2 and 4 weeks) to bone accretion late (increased BV/TV, Tb.Th and thickness of subchondral bone plate, and reduced Tb.Sp at 8 and 12 weeks). The TMD of both the BP and Tb displayed no significant changes at 2 and 4 weeks but decreased at 8 and 12 weeks. The mineral-to-collagen ratio showed a significant decrease from 4 weeks for the Tb and from 8 weeks for the BP after OA induction. Both the elastic modulus and hardness of the Tb showed a significant decrease from 4 weeks after OA induction. The BP showed a significant decrease in its elastic modulus from 8 weeks and its hardness from 4 weeks. Conclusion: The microarchitecture, mineralization and mechanical properties of subchondral bone changed in a time-dependent manner as OA progressed.

Abstract
BACKGROUND End-stage renal disease (ESRD) is fatal if untreated. In the absence of transplant, approximately 50 % of dialysis patients die within 5 years. Although more frequent and/or longer haemodialysis (high-dose HD) improves survival, this regimen may add to the burden on dialysis services and healthcare costs. This systematic review summarised the cost effectiveness of high-dose HD compared with conventional HD. METHODS English language publications reporting the cost-utility/effectiveness of high-dose HD in adults with ESRD were identified via a search of MEDLINE, Embase, and the Cochrane Library. Publications comparing any form of high-dose HD with conventional HD were reviewed. RESULTS Seven publications (published between 2003 and 2014) reporting cost-utility analyses from the public healthcare payer perspective were identified. High-dose HD in-centre was compared with in-centre conventional HD in one US model; all other analyses (UK, Canada) compared high-dose HD at home with in-centre conventional HD (n = 5) or in-centre/home conventional HD (n = 1). The time horizon varied from one year to lifetime. Similar survival for high-dose HD and conventional HD was assumed, with the impact of higher survival only assessed in the sensitivity analyses of three models. High-dose HD at home was found to be cost effective compared with conventional HD in all six analyses. The analysis comparing high-dose HD in-centre with conventional in-centre HD produced an incremental cost-effectiveness ratio generally acceptable for the USA, but not for Europe, Canada or Australia. CONCLUSION High-dose HD can be cost effective when performed at home. Future analyses assuming survival benefits for high-dose HD compared with conventional HD are needed.

Abstract
OBJECTIVES Parenteral nutrition (PN) is critical in neonatal and pediatric care for patients unable to tolerate enteral feeding. This study assessed the total costs of compounding PN therapy for neonates, infants and children. METHODS Face-to-face and telephone interviews were conducted in 12 hospitals across four European countries (Belgium, France, Germany and UK) to collect information on resources utilized to compound PN, including nutrients, staff time, equipment cost and supplies. A bottom-up cost model was constructed to assess total costs of PN therapy by assigning monetary values to the resource utilization using published list prices and interview data. RESULTS A total of 49,922 PN bags per year were used to treat 4295 neonatal and pediatric patients among these hospitals. The daily total costs of one compounded PN bag for neonates in the 12 hospitals across the four countries equalled euro 55.16 (Belgium euro 53.26, France euro 46.23, Germany euro 64.05, UK Ł 37.43/\[euro]42.86). Overall, nutrients accounted for 25% of total costs, supplies 18%, wages 54% and equipment 3%. Average costs per bag for infants <2 year were euro 84.52 (euro 74.65 in Belgium, euro 83.84 in France, euro 92.70 in Germany and Ł 52.63/euro 60.26 in the UK), and for children 2-18 years euro 118.02 (euro 93.85 in Belgium, euro 121.35 in France, euro 124.54 in Germany and Ł 69.49/euro 79.56 in the UK), of which 63% is attributable to nutrients and 28% to wages. CONCLUSION The data indicated that PN costs differ among countries and a major proportion was due to staff time (Ł 1=euro 1.144959).

Abstract
Zearalenone (ZEA), an estrogenic mycotoxin, is produced mainly by Fusarium fungi. Previous studies indicated that acute ZEA exposure induced oxidative stress and damage in multiple organs. Therefore, the present study was designed to investigate the adverse effects of dietary ZEA (1.1 to 3.2 mg/kg of diet) on oxidative stress and organ damage in postweaning gilts. A total of 20 gilts (Landrace × Yorkshire × Duroc) weaned at d 21 with an average BW of 10.36 ± 1.21 kg was used in the study. Gilts were housed in a temperature-controlled room, divided into 4 treatments, and fed a basal diet only (control) or basal diet supplemented with purified ZEA at a dietary concentration of 1 (ZEA1), 2 (ZEA2), or 3 (ZEA3) mg/kg of diet for 18 d ad libitum. The actual ZEA contents (analyzed) were 0, 1.1 ± 0.02, 2.0 ± 0.01, and 3.2 ± 0.02 mg/kg for control, ZEA1, ZEA2, and ZEA3, respectively. Gilts fed different amounts of dietary ZEA grew similarly with no difference (P > 0.05) in feed intake. Vulva size increased linearly over the 18 d of feeding in gilts fed diets containing 1.1 mg of ZEA/kg or greater (P < 0.001). Relative weight of genital organs, liver, and kidney increased linearly (P < 0.05) in a ZEA-dose-dependent manner. Serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamate transferase, urea, and creatinine (P < 0.05), and malondialdehyde concentrations in both serum and liver (P < 0.001) were also increased linearly in a ZEA-dose-dependent manner. However, spleen relative weight (P = 0.002) and activities of total superoxide dismutase and glutathione peroxidase (in both serum and liver (P < 0.05) were decreased linearly as dietary ZEA increased. Results showed that besides genital organs, the liver, kidney, and spleen may also be target tissues in young gilts fed diets containing 1.1 to 3.2 mg of ZEA/kg for 18 d. Increased key liver enzymes in the serum suggest progressive liver damage caused by feeding ZEA, and an increase in oxidative stress in gilts is another potential impact of ZEA toxicity in pigs.

Abstract
Recent studies have revealed that the prevalence of Wolbachia in arthropods is attributable not only to its vertical transmission, but also to its horizontal transfer. In order to assess the horizontal transmission of Wolbachia between predator and prey, arthropods belonging to 11 spider families and six insect families were collected in the same field of rice. The distribution of Wolbachia in these arthropods was detected by diagnostic PCR amplification of the wsp (Wolbachia outer surface protein gene) and 16S rDNA genes. Nurscia albofasciata Strand (Araneae: Titanoecidae), Propylea japonica Thunberg (Coleoptera: Coccinellidae), Paederus fuscipes Curtis (Coleoptera: Staphylinidae), and Nilaparvata lugens Stal (Homoptera: Delphacidae) were infected with Wolbachia. This is the first report of infection of N. albofasciata and P. fuscipes by Wolbachia. No direct evidence indicated the existence of horizontal transmission of Wolbachia between predator and prey.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix astragali, Radix codonopis, Herba epimedii and Radix glycyrrizae are 4 plants commonly used in Chinese traditional medicine or veterinary medicine to improve immune functions against chronic diseases in humans and animals. AIM OF THE STUDY We compared immunological enhancement by 4 herbal extracts in clinical healthy chickens or immunosuppressed chickens singly and in combination. MATERIALS AND METHODS Water extracts of 4 herbs individually and in different combinations were supplemented in drinking water. Hemagglutination inhibition (HI) antibody titers against Newcastle disease virus (NDV) and H5 avian influenza virus (H5-AIV) after vaccination were measured as indicators to evaluate immunological stimulation across groups supplemented with different herbal extracts. The experiments were conducted in both clinically healthy chickens and chickens with immunosuppression induced by reticuloendotheliosis virus (REV) infection. RESULTS In clinically healthy chickens HI antibody titers against NDV and H5-AIV after vaccination were not influenced by supplementation with the herbal extracts of Radix astragali, Radix codonopis, Herba epimedii and Radix glycyrrizae in drinking water. In chicks with REV-induced immunosuppression, however, supplementation of some herbal extracts significantly increased HI antibody titers to NDV and H5-AIV when compared to the immunosuppressed control group (P<0.01), but the titers were still lower than those in chicks not infected by REV. The 4 herbal mixtures produced the best enhancement among various combinations. The components of the herbal extract were water soluble and treatment by ether had no influence on immunological enhancement. The molecular weights of the active components of the herbal extracts were in the range of 10,000-100,000 Da. CONCLUSION Our results show that the herbal extract supplementation in drinking water can induce an immune stimulation response in immunosuppressed chickens. It suggests that chickens with REV infection-induced immunosuppression could be used as an experiment model for determination of immunological enhancement effects of some herbal components.

Abstract
OBJECTIVE To clarify the clinicopathologic significance of immunohistochemistry for proliferative activity and oncoprotein expression in astrocytic tumors. STUDY DESIGN Ninety-seven cases of brain astrocytic tumors with histologic grading and follow-up data were investigated with immunohistochemistry and image analyzer to detect the expression of proliferating cell nuclear antigen (PCNA), silver-binding nucleolar organizer regions (AgNORs) and several oncoproteins. RESULTS PCNA was significantly related to AgNORs, grading and prognosis of astrocytomas. The frequency of mutant p53 protein expression was higher in grade 2-4 astrocytomas than in grade 1. Epidermal growth factor (EGF) (37.1%), EGF receptor (83.5%) and p21ras (42.3%) expression levels were related to neither the grade nor prognosis of the tumors. The positive ratios of p53 antibodies were higher in grades 2-4 than in grade 1, and the intensities correlated with PCNA but not with prognosis. CONCLUSION Aberrations of c-erbB-2, p21ras, EGF and EGF receptor might be early events in the initiation and progression of astrocytomas, whereas p53 overexpression is involved in all the stages. Immunohistochemical detection had no prognostic value. PCNA could be important to the evaluation of astrocytoma malignancy.

Abstract
OBJECTIVE To investigate the correlation of angiogenic factor expression levels with the degrees of malignancy and vascularity and their clinicopathologic significance in astrocytomas. STUDY DESIGN Factor VIII-related antigen (FVIII-RAg) was used as the marker of endothelia and basic fibroblast growth factor (bFGF); FGF receptor (FGFR)-1 and vascular endothelial growth factor (VEGF) were qualitatively and quantitatively detected with immunohistochemistry and image analysis in 61 brain astrocytomas. The correlation with tumor grades, angiogenesis and prognosis was studied. RESULTS Measurement of FVIIIRAg expression could describe endothelial proliferation and vascularity, which were related to grade of tumor and prognosis. bFGF and VEGF expression levels in neoplastic astrocytes and endothelia were significantly different in various grades of astrocytoma. These angiogenic factors affected the positive reaction areas and integral optical densities of FVIII-RAg as well as survival time. In contrast, the expression of FGFR-1 was related to neither bFGF nor FVIIIRAg and had no significant effect on tumor malignancy. CONCLUSION Positive regulation by bFGF and autocrine/paracrine VEGF contributes to the growth and angiogenesis of astrocytomas. Measurement of endothelial cell proliferation with FVIIIRAg in tumor stroma and quantitative detection of angiogenic factor levels in neoplastic cells had prognostic value in brain astrocytomas. The results also indicate that inhibiting bFGF and VEGF expression and/or blocking their effects could be a very useful therapeutic strategy for malignant gliomas.

Abstract
Nuclear DNA content was measured by microspectrophotometry in 40 biopsy specimens from patients with large bowel polyps (10 juvenile polyps and inflammatory polyps, 25 adenoma subdivided into 3 groups with 10 Grade I, 10 Grade II and 5 Grade III, 5 cancerous degeneration), and 5 normal epithelium of large intestine. The mean DNA value increased steadily as follows: normal epithelium of intestine (13.54 +/- 1.76 Au); juvenile polyps and inflammatory polyps (14.89 +/- 0.40 Au); adenoma Grade III (21.96 +/- 0.92 Au); cancerous degeneration (24.47 +/- 1.48 Au). The difference in DNA value in these groups was statistically significant (P less than 0.05-0.01). These results suggest that measurement of nuclear DNA content may serve as an objective quantitative parameter for diagnosis of large bowel carcinomatous change of polyps and classification of polypoid adenomas.

Abstract
The method which combines the removable appliance with a headgear attached to the maxillary dentition is widely used in treatment of the maxillary protrusion of growing children. The initial reaction of maxillary complex caused by the removable appliance retraction was studied by the holographic interferometry. In this paper, the results indicate that when the pull applied along the occlusal plane the maxilla was moved downward, whereas when the pall applied along the occlusal plane at 15 the maxilla was moved upward and backward. The advantage of this method and model of the experimentation was discussed in the paper.

Abstract
Nuclear DNA content was measured by microspectrophotometry in 15 biopsy specimens from patients with G-I smooth muscle tumors (3 leiomyomas and 12 leiomyosarcomas subdivided into 3 groups with 4 cases to each). The mean DNA value increased steadily as follows: leiomyomas (14.39 +/- 0.62 Au); leiomyosarcoma Grade I (19.78 +/- 2.39 Au); Leiomyosarcoma Grade II (26.39 +/- 1.60 Au); leiomyosarcoma Grade III (30.66 +/- 2.39 Au). The difference of DNA value in the 4 groups had statistical significance (P less than 0.05-0.01). These results suggest that microspectrophotometric measurement of nuclear DNA content may serve as an objective quantitative method for diagnosis of G-I tract smooth muscle tumors and classification of leiomyosarcoma.
