Abstract
BACKGROUND Cold atmospheric plasma (CAP) has been widely used in biomedical research, especially in vitro cancer therapy. Cutaneous squamous cell carcinoma (CSCC) is a malignant tumor originating from epidermal keratinocytes. However, the mechanism of CAP therapy on CSCC remains unclear. METHODS AND RESULTS The animal models of CSCC induced by 7,12-dimethylbenz(a) anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA) were constructed. For the CAP treatment group, after each TPA application, CAP was administered for 3 min twice weekly after drying. HE staining were used to detect the pathological status of tumor tissue in each group. The levels of PCNA, Bcl-2, Bax, MMP2 and MMP9 were evaluated by western blot and qPCR. TUNEL staining were used to detect apoptosis in tumor tissues. In vivo, serum samples were used for ELISA of total ROS. MTT assay was used to detect the viability of A431 cells. Western blot and qPCR were used to detect the levels of PCNA, Bcl-2, Bax, MMP2 and MMP9 in A431 cells. A431 cell proliferation was examined by colony formation assay. The proportions of apoptosis of A431 cells were detected by flow cytometry. Transwell assessed the ability of A431 cells migration and proliferation. We found that CAP could induce skin cancer cells apoptosis and inhibit the progress of skin cancer. Through experiments in vitro, reactive oxygen species (ROS) generated by N-acetylcysteine (NAC) and CAP inhibited the proliferation and migration of A431 skin cancer cells while promoting apoptosis. CONCLUSIONS These evidences suggest the protective effect of CAP in CSCC, and CAP has the potential clinical application of CSCC.

Abstract
OBJECTIVE To investigate the screening value and correlation of body measurement indicators for metabolic syndrome(MS) and to provide evidence for MS screening. METHODS Through a cross-sectional research approach, data from individuals aged 18 and above who participated in health examinations at the North Health Management Center of Sichuan Provincial People's Hospital from 2018 to 2020 were reviewed. Data including height, weight, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, smoking history, and alcohol consumption history were collected. Subsequently, a body shape index(ABSI), body roundness index(BRI), body adiposity index(BAI), abdominal volume index(AVI), relative fat mass index(RFM), and body mass index(BMI) were computed. The individuals were then divided into MS and non-MS groups. The value of body measurement indices in screening for MS in the population aged 18 and above was assessed using ROC curves. Regression analysis was employed to explore the correlation between body measurement indices and MS. RESULTS A total of 73 411 valid health examination data were obtained, including 44 426 males and 28 985 females. The MS group comprised 9181 males(21%) and 1668 females(6%). In the comparison between the MS and non-MS groups, there were statistically significant differences in ABSI((0.08±0.00) vs. (0.08±0.00)), BRI((4.95±0.67) vs. (4.17±0.68)), BAI((28.08±3.52) vs. (26.39±3.39)), AVI((17.51±2.77) vs. (12.85±2.91)), BMI((27.15±2.99) vs. (23.00±3.04)) and RFM((29.77±5.35) vs. (27.13±6.39))(P<0.05). Univariate Logistic regression analysis showed that ABSI(OR=2.303, 95%CI 1.190-4.457), BRI(OR=4.596, 95%CI 4.446-4.752), BAI(OR=1.144, 95%CI 1.137-1.151), AVI(OR=1.668, 95%CI 1.652-1.684), RFM(OR=1.067, 95%CI 1.064-1.071) and BMI(OR=1.516, 95%CI 1.503-1.528) were associated with MS(P<0.05). Multifactorial Logistic regression analysis corrected for sex, age, smoking and alcohol consumption showed that ABSI(OR=1.767, 95% CI 4.237-7.371), BRI(OR=5.441, 95% CI 5.228-5.663), BAI(OR=1.269, 95% CI 1.260-1.279), AVI(OR=1.648, 95% CI 1.631-1.665), RFM(OR=1.504, 95% CI 1.491-1.517) and BMI(OR=1.508, 95% CI 1.495-1.522) were associated with MS(P<0.05). The ROC curve analysis showed that in adults, the AVI had the highest screening value for MS in males(AUC=0.855, optimal cutoff value=16.18), followed by RFM(AUC=0.844, optimal cutoff value=25.71), BMI(AUC=0.811, optimal cutoff value=25.21), BRI(AUC=0.793, optimal cutoff value=4.39), BAI(AUC=0.709, optimal cutoff value=25.88), and ABSI(AUC=0.671, optimal cutoff value=0.08). In adult females, the RFM had the highest screening value for MS(AUC=0.918, optimal cutoff value=37.01), followed by AVI(AUC=0.911, optimal cutoff value=13.43), BRI(AUC=0.901, optimal cutoff value=4.71), BMI(AUC=0.860, optimal cutoff value=23.94), ABSI(AUC=0.804, optimal cutoff value=0.08), and BAI(AUC=0.797, optimal cutoff value=29.92). CONCLUSION ABSI, BRI, BAI, AVI, BMI and RFM are all capable of screening for MS. Among males, AVI has the highest screening value for MS, followed by RFM, BMI, BRI, BAI and ABSI. Among females, RFM has the highest screening value for MS, followed by AVI, BRI, BMI, ABSI and BAI. ABSI, BRI, BAI, AVI, RFM and BMI are positively correlated with MS.

Abstract
Cold atmospheric plasma has been widely applied in medical treatment clinically, especially skin diseases. However, the mechanism of cold atmospheric plasma on the treatment of skin diseases is still undefined. In this study, dinitrofluorobenzene-induced atopic dermatitis mice model was constructed. Cold atmospheric plasma was able to decrease skin cells apoptosis, relieve skin inflammation, ER stress and oxidative stress caused by dinitrofluorobenzene stimulation, which was mediated by cold atmospheric plasma-induced MANF expression. In terms of mechanism, hypoxia-inducible factor-1α expression was increased intracellularly after cold atmospheric plasma treatment, which further bound to the promoter region of manf gene and enhanced MANF transcriptional expression. This study reveals that cold atmospheric plasma has a positive effect on atopic dermatitis treatment, also demonstrates the regulatory mechanism of cold atmospheric plasma on MANF expression via HIF-1α, which indicates the potential medical application of cold atmospheric plasma for atopic dermatitis treatment.

Objective
Previous studies have demonstrated that the levels of asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide (NO) synthesis, are strongly associated with hypertension, diabetes, and cardiovascular diseases. Profilin-1, an actin-binding protein, has been documented to be involved in endothelial injury and in the proliferation of vascular smooth muscle cells (VSMCs) resulting from hypertension. However, the role of profilin-1 in ADMA-induced vascular injury in hypertension remains largely unknown.
Methods
Forty healthy subjects and forty-two matched patients with essential hypertension were enrolled, and the related indexes of vascular injury in plasma were detected. Rat aortic smooth muscle cells (RASMCs) were treated with different concentrations of ADMA for different periods of time and transfected with profilin-1 shRNA to interrupt the expression of profilin-1. To determine the role of the Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway, RASMCs were pretreated with AG490 or rapamycin. The expression of profilin-1 was tested using real-time PCR and western blot analysis. Cell proliferation was measured by flow cytometry and MTT assays.
Results
Compared with healthy subjects, the levels of ADMA and profilin-1 were markedly elevated in hypertensive individuals, while the levels of NO were significantly decreased(P < 0.05). In vitro, studies showed ADMA induced profilin-1 expression in a concentration- and time-dependent manner in RASMCs (P < 0.05), concomitantly with promoting the proliferation of RASMCs. Furthermore, ADMA-mediated proliferation of RASMCs and up-regulation expression of profilin-1 were inhibited by blockade of the JAK2/STAT3 pathway or knockdown of profilin-1.
Conclusions
Profilin-1 implicated in the ADMA-mediated vascular lesions in hypertension. Abstract Figure 12 Abstract Figure 3

Abstract
This paper explores the complex nexus between the global oil prices and the food prices of the Middle East and North Africa (MENA) region during the period 2000-2020. Both linear and nonlinear models of the autoregressive distributed lag (ARDL) approach are adapted into panel data form to investigate the symmetrical and asymmetrical influence of oil prices on food prices. The key results are summarized: (i) the long-term effect of oil prices on food prices is significantly positive including both oil-exporting and oil-importing nations. The positive impact on oil exporters-due to higher oil revenues-is greater than importing nations, leading to an increased demand for food. Additionally, the effect on oil exporters is negative and significant in the short term but not significant for importers. (ii) The nonlinear ARDL panel analysis for the whole MENA sample confirms the presence of negative short-term asymmetric behaviour due to the heterogeneous response within the oil-importing and oil-exporting samples, while in the long term, the asymmetric effect is positive, indicating that food prices increase regardless of fluctuations in oil prices. (iii) The nonlinear ARDL results using time series affirm the absence of an asymmetric nexus among oil and food prices for some oil-exporting nations (including Kuwait, Saudi Arabia, United Arab Emirates) and Tunisia within the oil-importing group. However, the food prices of other countries are asymmetric to the oil price. This study provides recommendations that are useful to MENA countries to establish a stable mechanism for oil and food prices to ensure food security in the region.

Abstract
Atmospheric pressure cold plasma has shown multiple biological effects of anti-bacteria and anti-cancer. In this study, the effect of atmospheric pressure cold plasma on respiratory inflammation and oxidant stress is explored. Tunicamycin was used to stimulate human bronchial epithelial cells (HBECs) and A549 cells for inflammatory response and oxidative stress, followed by atmospheric pressure cold plasma treatment. For HBECs and A549 cells, atmospheric pressure cold plasma was able to alleviate tunicamycin-induced cell proliferation inhibition, inflammation and oxidant stress, and enhance nuclear factor-erythroid-2-related factor 2 (NRF2) pathway activation. Moreover, NRF2/ARE (anti-oxidant response elements) pathway was involved in the regulation of atmospheric pressure cold plasma on tunicamycin-induced oxidative stress. These results suggest the positive effect of atmospheric pressure cold plasma on inflammation and oxidant stress of respiratory system, indicating the therapeutic potential of atmospheric pressure cold plasma for respiratory diseases.

Abstract
Twisted two-dimensional van der Waals (vdW) heterostructures have unlocked a new means for manipulating the properties of quantum materials. The resulting mesoscopic moiré superlattices are accessible to a wide variety of scanning probes. To date, spatially-resolved techniques have prioritized electronic structure visualization, with lattice response experiments only in their infancy. Here, we therefore investigate lattice dynamics in twisted layers of hexagonal boron nitride (hBN), formed by a minute twist angle between two hBN monolayers assembled on a graphite substrate. Nano-infrared (nano-IR) spectroscopy reveals systematic variations of the in-plane optical phonon frequencies amongst the triangular domains and domain walls in the hBN moiré superlattices. Our first-principles calculations unveil a local and stacking-dependent interaction with the underlying graphite, prompting symmetry-breaking between the otherwise identical neighboring moiré domains of twisted hBN. Here, the authors investigate the lattice dynamics of twisted hexagonal boron nitride layers via nano-infrared spectroscopy, showing local and stacking-dependent variations of the optical phonon frequencies associated to the interaction with the graphite substrate.

Abstract
The time-resolved magneto-optical (MO) Voigt effect can be utilized to study the Néel order dynamics in antiferromagnetic (AFM) materials, but it has been limited for collinear AFM spin configuration. Here, we have demonstrated that in Mn3Sn with an inverse triangular spin structure, the quench of AFM order by ultrafast laser pulses can result in a large Voigt effect modulation. The modulated Voigt angle is significantly larger than the polarization rotation due to the crystal-structure related linear dichroism effect and the modulated MO Kerr angle arising from the ferroic ordering of cluster magnetic octupole. The AFM order quench time shows negligible change with increasing temperature approaching the Néel temperature (TN), in markedly contrast with the pronounced slowing-down demagnetization typically observed in conventional magnetic materials. This atypical behavior can be explained by the influence of weakened Dzyaloshinskii–Moriya interaction rather than the smaller exchange splitting on the diminished AFM order near TN. The temperature-insensitive ultrafast spin manipulation can pave the way for high-speed spintronic devices either working at a wide range of temperature or demanding spin switching near TN. Mn3Sn is an anti-ferromagnetic material which displays a large magneto-optical Kerr effect, despite lacking a ferromagnetic moment. Here, the authors show that likewise, Mn3Sn, also presents a particularly large magneto-optical Voigt signal, with a negligible change in the quench time over a wide temperature range.

Abstract
Background Numerous studies have shown that long noncoding RNA (lncRNA) is involved in gastric cancer (GC). A relevant microarray containing gastric cancer-related lncRNAs was downloaded from The Cancer Genome Atlas database. Methods qRT-PCR was used to analyze LINC00565 and AKT3 expression in tumor tissues and cell lines. Proliferative, colony formation and apoptotic abilities of GC cells after transfection of sh-LINC00565 were determined by CCK-8, colony formation assay and flow cytometry, respectively. RIP was enrolled to detect the interaction between LINC00565, AKT3 and miR-665. Dual luciferase assay was used to confirm the relation between miR-665 and LINC00565 and AKT3. Results Expression level of LINC00565 in GC tissue was highly expressed in GC, which was negatively correlated to prognosis of GC patients. The results showed that knockdown of LINC00565 decreased proliferative and colony formation abilities, and induced apoptosis of GC cells. Pearson analysis showed that LINC00565 was positively correlated with AKT3. Besides, AKT3 was significantly up-regulated in GC. In addition, knockdown of LINC00565 down-regulated AKT3. In order to explore the mechanism, we found that miR-665 could bind to LINC00565 by bioinformatics. Dual-luciferase reporter gene assay and RIP assay both verified the binding relationship between miR-665 and AKT3. Finally, rescue experiments were carried out to explore whether AKT3 could reverse the anti-cancer effect of low-level LINC00565 on GC development. Conclusion In summary, the expression of LINC00565 is upregulated in GC. LINC00565 can be used as the sponge of miR-665 to up-regulate the expression of AKT3, thus promoting the progression of GC.

Abstract
1. Generating a robust egg albumen is one of the major factors contributing to interior egg quality owing to its nutritive value and superior appearance. However, the genetic factors regulating the proportion of thick albumen are poorly understood. 2. In this study, 1330 eggs were collected from 450 Rhode Island White layers, aged 40 weeks, to measure egg compositional traits for three successive days. The restricted maximum likelihood method was applied to estimate genetic parameters for the thick-to-thin albumen ratio and other egg compositional traits. A univariate animal model was fitted to calculate heritability for each trait. 3. The heritabilities of egg weight, yolk weight, albumen height, Haugh units, percentages of yolk, thick albumen, thin albumen and the thick-to-thin albumen ratio were 0.32, 0.34, 0.28, 0.47, 0.61, 0.39, 0.31, and 0.45, respectively. The percentage of thick albumen was negatively correlated genetically with all traits, and percentage of thin albumen was negatively correlated genetically with all traits except for Haugh units. The thick-to-thin albumen ratio was positively correlated genetically with egg weight, albumen height and Haugh units, with correlations ranging from 0.21 to 0.54. 4. The results indicated that the percentage of thick albumen and the thick-to-thin albumen ratio were found to be moderately to highly heritable, and selection for the thick-to-thin albumen ratio could be conducive to the improvement of egg albumen quality.

Abstract
Non-thermal plasma (NTP) treatment has been proposed as a potential approach for cancer therapy for killing cancer cells via generation of reactive oxygen species (ROS). As an antioxidant protein, Heme oxygenase-1 (HO-1) has been known to protect cells against oxidative stress. In this paper, we investigated the role of HO-1 activation in NTP-induced apoptosis in A549 cells. Distinctly increased ROS production and apoptosis were observed after NTP exposure. NTP exposure induced HO-1 expression in a dose- and time-dependent manner via activating the translocation of Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) from cytoplasm to nucleus. Furthermore, inhibiting HO-1 activation with its specific inhibitor, ZnPP, increased "killing" effect of NTP. Knocking down HO-1 or Nrf2 with the special siRNA also led to elevated ROS level and enhanced NTP-induced cell death. In addition, the c-JUN N-terminal kinase (JNK) signaling pathway was shown to be involved in NTP-induced HO-1 expression. Interestingly, a higher resistance to NTP exposure of A549 cell compared to H1299 and H322 cells was found to be linked to its higher basal level of HO-1 expression. These findings revealed that HO-1 could be considered as a potential target to improve the effect of NTP in cancer therapy.

Abstract
Cost-effective high-density (HD) genotypes of livestock species can be obtained by genotyping a proportion of the population using a HD panel and the remainder using a cheaper low-density panel, and then imputing the missing genotypes that are not directly assayed in the low-density panel. The efficacy of genotype imputation can largely be affected by the structure and history of the specific target population and it should be checked before incorporating imputation in routine genotyping practices. Here, we investigated the efficacy of imputation in crossbred dairy cattle populations of East Africa using 4 different commercial single nucleotide polymorphisms (SNP) panels, 3 reference populations, and 3 imputation algorithms. We found that Minimac and a reference population, which included a mixture of crossbred and ancestral purebred animals, provided the highest imputation accuracy compared with other scenarios of imputation. The accuracies of imputation, measured as the correlation between real and imputed genotypes averaged across SNP, were around 0.76 and 0.94 for 7K and 40K SNP, respectively, when imputed up to a 770K panel. We also presented a method to maximize the imputation accuracy of low-density panels, which relies on the pairwise (co)variances between SNP and the minor allele frequency of SNP. The performance of the developed method was tested in a 5-fold cross-validation process where various densities of SNP were selected using the (co)variance method and also by alternative SNP selection methods and then imputed up to the HD panel. The (co)variance method provided the highest imputation accuracies at almost all marker densities, with accuracies being up to 0.19 higher than the random selection of SNP. The accuracies of imputation from 7K and 40K panels selected using the (co)variance method were around 0.80 and 0.94, respectively. The presented method also achieved higher accuracy of genomic prediction at lower densities of selected SNP. The squared correlation between genomic breeding values estimated using imputed genotypes and those from the real 770K HD panel was 0.95 when the accuracy of imputation was 0.64. The presented method for SNP selection is straightforward in its application and can ensure high accuracies in genotype imputation of crossbred dairy populations in East Africa.

Abstract
We present finite element (FE) modeling approaches of ear mechanics including 3-dimensional (3D) reconstruction of the human middle and inner ear. Specifically, we demonstrate a semi-automatic methodology for the 3D reconstruction of the inner ear structures, a FE harmonic response model of the middle ear to predict the stapes footplate frequency response, a 2D FE slice model of the cochlea for the coupled response at the micromechanical level for either acoustic or electrical excitation and a coupled FE middle ear model with a simplified cochlea box model to simulate the basilar membrane velocity in response to acoustic excitation. The proposed methodologies are validated against experimental and literature data and the results are in good agreement.

Abstract
BACKGROUND Circulating miRNAs are potential biomarkers of the pathogenesis of certain diseases and in monitoring therapeutic responses. We hypothesized that serum miR-29 can determine risk of acute cardiac allograft rejection. METHODS Peripheral vein blood was collected from 50 healthy volunteers and 506 patients during post-transplant surveillance. Serum cardiac troponin I (cTnI) and miR-29 was detected by ELISA and qRT-PCR assay respectively. Rejection risk was defined as International Society of Heart and Lung Transplant score from leukocyte infiltration of an endomyocardial biopsy. No evidence of rejection was defined as grade R0, mild as R1, moderate as 2R and severe as 3R. Specificity and sensitivity of miR-29 to discriminate rejection was determined by the area under the curve (AUC) of receiver operating characteristic curve analysis. Correlations between miR29 and rejection grade were compared. RESULTS Serum miR-29 was 100.8 ± 42.4 copies/μl in R0 groups (P = 0.164 versus controls), 537.5 ± 84.3 copies/μl in R1 groups (P = 0.024) and 1478.4 ± 198.7 copies/μl in the joint R2/R3 groups (P = 0.001). MiR-29 was 1963.5 ± 214.7 six months after transplantation, 1242.5 ± 103.8 after a year, 825.6 ± 58.2 after 2 years, 413.8 ± 61.9 after 3 years and 270.6 ± 34.6 ng/mL after 4 years (P < 0.001). The level of miR-29 correlated positively with cTnI, NT-proBNP, white blood cell counts, and negatively with lymphocyte counts (all P < 0.001). The AUC values (95% CI) for discriminating R0 and R1 was 0.81 (0.75-0.89), and was 0.79 (0.72-0.86) for R0 and R2/R3 (both P < 0.01). CONCLUSION miR-29 is a promising predictor of the risk of heart transplant rejection.

Abstract
Selection decisions in genomic selection schemes are made based on genomic breeding values (GBV) of candidates. Thus, the accuracy of GBV is a relevant parameter, as it reflects the stability of prediction and the possibility that the GBV might change when more information becomes available. Accuracy of genomic prediction defined as the correlation between GBV and true breeding values (TBV), however, is difficult to assess, considering TBV of the candidates are not available in reality. In previous studies, several methods were proposed to assess the accuracy of GBV including methods using population parameters or parameters inferred from mixed-model equations. In practice, most approaches tended to overestimate the accuracy of genomic prediction. We thus tested approaches used in previous studies in order to assess the magnitude of bias. Analyses were performed based on simulated data under a variety of scenarios mimicking different livestock breeding programmes. Furthermore, we proposed a novel method and tested it both with simulated data and in a real Holstein data set. The new method provided a better prediction for the accuracy of GBV in the simulated scenarios.

Abstract
The excess sludge from Up-flow anaerobic sludge bed (UASB) reactor operated on source separated toilet wastewater is a potential source of nutrients and organic matter. It can be further stabilized and dried by composting and applied as a soil amendment. Presence of pathogens, heavy metals and micropollutants in the compost derived from anaerobic sludge is thus undesirable. This paper focuses on removal of micropollutants, typically present in domestic wastewater, via composting of UASB sludge with waste wood. Estrone, diclofenac, ibuprofen, metoprolol, carbamazepine, galaxolide and triclosan were spiked to a mixture of UASB sludge and waste wood. Their concentrations were monitored during 92 days of composting at controlled temperature conditions. All studied micropollutants were removed at various rates with overall removal ranging from 99.9% for ibuprofen, diclofenac and estrone to 87.8% for carbamazepine. Accumulation of methyltriclosan as by-product of triclosan degradation was observed. The prospects and limitations of the integration of a composting process into Source Separated Sanitation concepts are discussed.

Abstract
OBJECTIVE To investigate the feasibility of temporary ectopic implantation of amputated fingers and dorsalis pedis flaps for thumb reconstruction and skin defect repair of the hand. METHODS Between February 2006 and February 2012, 9 patients with thumb amputation having no replanted condition were treated. There were 7 males and 2 females with an average age of 35 years (range, 20-45 years). The injury causes included explosive injury in 1 case, puncher injury in 1 case, stiring machine injury in 1 case, gear injury in 3 cases, and heavy pound injury in 3 cases. At 2-5 hours after injury, one-stage temporary ectopic implantation of amputated finger to foot was performed. After debridement, thumb defect was rated as degree III in 1 case, as degree IV in 3 cases, and as degree V in 5 cases. When amputated fingers survived completely after 1-4 months, the amputated finger was replanted to its anatomic position, skin defect was repaired with dorsalis pedis flap. The area of skin defect ranged from 5 cm x 4 cm to 7 cm x 6 cm. The area of flaps ranged from 6 cm x 5 cm to 8 cm x 7 cm. The donor site was repaired by the skin grafting. RESULTS Arterial crisis occurred in 1 case after 1 day of one-stage operation, and was cured after vascular exploration, and the amputated fingers survived in the others. The reconstructed thumbs and flaps survived after two-stage operation, and the skin graft at donor site survived. The patients were followed up 1-4 years (mean, 2.8 years). The reconstructed thumbs had good appearance and satisfactory opposition and finger-to-finger functions. According to the standard functional evaluation issued by Hand Surgery Association of Chinese Medical Association, the scores of survival fingers were 73-91 (mean, 84); the results were excellent in 7 cases and good in 2 cases with an excellent and good rate of 100%. CONCLUSION Temporary ectopic implantation of amputated finger to foot combined with dorsalis pedis flap can be used to reconstruct thumb and repair skin defect of the hand.

Abstract
A series of Co/Alq₃ granular films were deposited on silicon substrates using co-evaporation technique. Under the nonuniform illumination of a laser beam, lateral photovoltaic effect (LPE) was observed in the samples, with the optimal open-circuit position sensitivity of 34.7 mV/mm. The insertion of oxide layer results in the decrease of lateral photovoltage (LPV) and the irreversible LPE. The dependence of lateral photovoltaic effect on substrates was also briefly investigated. The possible mechanism was discussed.

Abstract
Due to the toxicity of dioxins, furans and heavy metals, there is a growing environmental concern on municipal solid waste incinerator (MSWI) fly ash in China. The purpose of this study is directed towards the volume-reduction of fly ash without any additive by thermal plasma and recycling of vitrified slag. This process uses extremely high-temperature in an oxygen-starved environment to completely decompose complex waste into very simple molecules. For developing the proper plasma processes to treat MSWI fly ash, a new crucible-type plasma furnace was built. The melting process metamorphosed fly ash to granulated slag that was less than 1/3 of the volume of the fly ash, and about 64% of the weight of the fly ash. The safety of the vitrified slag was tested. The properties of the slag were affected by the differences in the cooling methods. Water-cooled and composite-cooled slag showed more excellent resistance against the leaching of heavy metals and can be utilized as building material without toxicity problems.

Abstract
PURPOSE Axitinib, a potent and selective inhibitor of vascular endothelial growth factor receptors 1, 2, 3, is metabolized by cytochrome P450 3A4 and glucuronidation. This study evaluated the effect of rifampin, a potent inducer of drug-metabolizing enzymes, on axitinib plasma pharmacokinetics. Equal numbers of Japanese and Caucasian subjects were enrolled to assess the potential differences in axitinib pharmacokinetics between the two ethnicities. METHODS Forty healthy volunteers were randomized to receive 5 mg axitinib alone and with 600 mg rifampin. RESULTS Rifampin expectedly decreased AUCinf and Cmax of axitinib (geometric mean reduced by 79 and 71%, respectively). However, differences in axitinib pharmacokinetics were not observed between Japanese and Caucasian subjects (geometric mean ratios for axitinib treatment alone for AUCinf and Cmax were 103 and 96%). CONCLUSIONS The results support a common axitinib starting dose in both populations. Potent inducers of drug-metabolizing enzymes reduce axitinib exposure and dose adjustments may be needed for optimal efficacy.

Abstract
CP-690 550 inhibits Janus kinase 3 with nanomolar potency. In this dose-escalation study, we assessed the safety, tolerability, effects on lymphocyte subsets, and pharmacokinetics of CP-690 550 when coadministered with mycophenolate mofetil in stable renal allograft recipients for 28 days. Twenty-eight patients were enrolled. Six patients received CP-690 550 5 mg twice daily (BID), 6 patients received 15 mg BID, 10 patients received 30 mg BID, and 6 patients received placebo. The most frequent adverse events were infections and gastrointestinal (abdominal pain, diarrhea, dyspepsia, and vomiting). CP-690 550 15 mg BID and 30 mg BID were associated with a mean decrease in hemoglobin from baseline of 11% and a mean decrease in absolute natural killer cell counts of 50%. CP-690 550 30 mg BID was also associated with a mean increase in absolute CD19(+) B-lymphocytes of 130%. There were no changes in the number of neutrophils, total lymphocytes, platelets, or CD4(+) or CD8(+) T cells; clinical chemistry; vital signs; or electrocardiograms from the pretreatment baseline. Administration of CP-690 550 without a concomitant calcineurin inhibitor resulted in CP-690 550 exposures consistent with previous studies in nontransplant subjects. Additional dose-ranging studies are warranted to evaluate the safety and efficacy of CP-690 550 in renal transplant recipients over longer treatment duration.

Abstract
OBJECTIVE To study the relationship between human leukocyte antigen (HLA)-DRB1 and DQ alleles and the genetic susceptibility of type 1 diabetes in North Chinese children. METHODS Polymerase chain reaction (PCR) techniques were used to amplify the second exon of DRB1 and DQ alleles, after which sequence specific olignucleotide probe (SSOP) dot blot hybridization techniques were used to analyze the amplified products. RESULTS DRB1 * 0301, DQA1 * 0301, DQB1 * 0201 alleles and DRB1 * 0301-DQA1 * 0501-DQB1 * 0201 haplotype were significantly increased in patients, while DQA1 * 0103 and DQB1 * 0601 alleles were significantly increased in controls. The distribution of DR4 and DR9 haplotypes in patients and controls were not significantly different, but DR3/DR4 and DR4/DR9 heterozygotes were significantly increased in patients. CONCLUSIONS DRB1 * 0301, DQA1 * 0301 and DQB1 * 0201 confer susceptibility while DQA1 * 0103 and DQB1 * 0601 confer protection to type 1 diabetes. DRB1 * 0301-DQA1 * 0501-DQB1 * 0201 haplotype offers a predisposition to type 1 diabetes in North Chinese. Although the distribution of DR4 and DR9 in patients and controls had no significant difference, DR3/DR4 and DR3/DR9 heterozygotes were significantly increased in patients, showing that the susceptive effects of DR3 and DR4 or DR4 and DR9 haplotypes could be added up.

Abstract
The aim of this study was to evaluate the effect of immobilization on the mechanical properties of rabbit patellar tendon(PT). IN this study, the rabbit knee was immobilized in extension for 6 weeks, then the mechanical properteis of PT were investigated. The results showed that the stress-strain relationship of PT could be expressed with exponential functions, and there were significant differeces between the normal group and the immobilized group in their theoretical curves of stress-strain relationship and two material constants of PT. Also, significant differences were found in tensile strength and tangent modulus between the two groups, but the maximum load of PT in the immobilized group did not decrease significantly. On the basis of the findings listed above, it is believed that PT would remodel and change its mechanical properties in response to the changes of mechanical stress exerted on it when the knee is immobilized.

Abstract
OBJECTIVE To evaluate changes of auditory brainstem response (ABR) and its role in monitoring auditory functions during the brainstem surgery. METHODS The data of 400 ABRs from 5 operations for removal of astrocytic glioma, cavernomas or dermoid from the brainstem were analyzed. The changes in latencies, amplitudes and wavefroms were dynamically observed and statistically analyzed with t test and Factor analysis. RESULTS Surgical manipulations, such as stretching, separation and extrusion, induced the prolongation of ABR peaks and interpeak latencies of waves I, III, V. The amplitudes of waves decreased. Three out of 5 cases presented reversible changes in latencies and wave forms. The dynamical analysis showed: The maximal variable range of latency(LMVD) was more than 11.30%, the maximal reversible degree of latency(LMRD) was more than 53.85%, the time of convalescent half-value latency(LCHT) was around 8-40 min, AMVD was more than 40%, the AMRD was more than 200%, and the ACHT was around 5-40 min. In 2 out of the 5 patients the postoperative ABR latencies kept prolonged, some postoperative waves were malformed and difficult to be identified, One case died, another lost consciousness, their LMRDs were less than 33.33%. These findings suggested that surgical intervention had significant effects on the ABR latency (P < 0.01). CONCLUSION ABR offers a promise for sensitive detection of the brainstem function. Its latency, amplitude and waveform show us dynamic changes of the brainstem status and can be used as an index during the operation on the brainstem and its adjacent region.

Abstract
OBJECTIVE To investigate the sensitivity of Hep-2 cell lines in larynx squamous cell carcinoma to the taxol in vitro and to provide experimental basis for clinical therapy. METHOD Techniques of cell culture and randomized blank-contrast design were used. The degree and dose-dependency of taxol which induced growth inhibition in Hep-2 cell lines were observed and the alteration of cell cycle was analysed by flow cytomethy. RESULT All cells died at the concentration of taxol 1 x 10(-8) M; growth inhibition was observed clearly at the concentration of 5 x 10(-9) M and 2.5 x 10(-9) M. Flow cytometric data showed a G0/G1 arrest and apoptosis (28.96%) in two cell lines after exposure to taxol for 48 h at low and medium concentrations. CONCLUSION There is a high sensitivity of Hep-2 cell to taxol in vitro. The cells show G0/G1 arrest and apoptosis. This results may provide reliable guidance for treating largnx carcinoma.

Abstract
Dietary patterns were assessed in a prospective study of cardiovascular disease (CVD) risk factors in four Chinese populations: Beijing urban (BJ-U) and rural (BJ-R), Guangzhou urban (GZ-U) and rural (GZ-R). A total of 10,076 men and women 35-54 years old were surveyed in 1983-84 and resurveyed in 1987-88. Dietary data were obtained in a subsample of about 10% (n=169 BJ-U, 178 BJ-R, 198 GZ-U, 230 GZ-R). Three 24-hr recalls were collected on each participant in each survey. Comparison of mean intakes in the two periods showed increases in meat, poultry, fish (except GZ-R), eggs (rural only), milk (except BJ-R) and alcoholic beverages. The largest shifts were in meat intake (29%-39%), alcoholic beverages (71%-104%) and fats in the urban samples (33%-35%). These changes are reflected in increased mean intakes of animal protein, fat, saturated fatty acids (SFA) and higher Keys scores. Mean total fat intake now exceeds the PRC recommended range of 20-25% of energy in three of the four samples. During this period BMI increased in all samples especially among men (3% - 6%). These surveys, conducted during a period of rapid economic development in China, show that such changes promote shifts in dietary patterns and energy balance towards increased risk of cardiovascular disease.

Abstract
As part of the PRC-USA collaborative research project on the epidemiology of cardiovascular disease, baseline surveys were conducted in four random urban and rural samples in Guangzhou, Guangdong Province in southern China on 334 men and women aged 35-54 in the fall of 1983-84 with the aim of studying the correlation between dietary intakes and serum lipids. Methods standardized by the US Centers for Disease Control were used for measuring different parameters, and quality control was emphasized to assure comparability between workers and farmers. Three 24-hour recalls were collected from each participant in each survey. Mean values of daily intakes of nutrients per capita for the four groups were as follows: 59-69% kcal carbohydrate; 10-12% kcal protein; 22-26% kcal fat. Dietary total fat, saturated fatty acid (SFA), polyunsaturated fatty acid (PUFA) and cholesterol were higher in the urban than the rural areas. Mean levels of serum total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were 4.6 mmol/l, 1.1 mmol/l, 1.3 mmol/l and 2.8 mmol/l respectively. The TC, TG and LDL-C and HDL-C were significantly higher in the urban than the rural areas. Analyses of correlation showed that the Keys 'dietary lipid score' was positively associated with TC, LDL-C and HDL-C; specifically, dietary cholesterol was positively associated with serum TC. Saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) were positively correlated with HDL-C. It seems that the traditional dietary pattern of Guangzhou favours serum lipids being at an optimal level.

Abstract
The distribution of recombinant human interleukin-2 (rhIL-2) after intravenous administration of 125I- or U-14C-labeled rhIL-2 is reported in the major organs of the rat. Five minutes after the administration of U-14C-labeled rhIL-2, the radioactivity had been rapidly cleared from the plasma, while 38% of the dose was found in the kidneys, confirming that the major site of clearance for rhIL-2 is the kidney. After 1 h, a large fraction of the radioactivity had disappeared from the kidney and was found in the carcass. When the same experiments were carried out with 125I-labeled rhIL-2, comparable distribution results were obtained: Preferential accumulation of 125I radioactivity (37.4%) was found in the kidney at 5 min after iv administration of 125I-labeled rhIL-2. One hour after dosing 125I label was predominantly present in the carcass (46%) and skin (15%). Similar percentages of the dose of 125I or 14C radioactivity were present in other organs or tissues. The present study indicates a similar distribution of the radiolabel in selected tissue and organs regardless of whether 14C or 125I was employed.
