Abstract
Objective: To establish a method for the determination of 4-methyl-2-pentanol in the air of workplace by gas chromatography. Methods: In January 2022, 4-methyl-2-pentanol in the air of workplace was collected by activated carbontube, eluted with dichloromethane-methanol (95∶5, V/V), separated by capillary column and determined by gas chromatogram. Results: The limit of detection for 4-methyl-2-pentanol was 0.04 μg/ml. The linear range of 4-methyl-2-pentanol was 0.16-1616.60 μg/ml, with the regression equation of y=1.94x-5.48, and the coefficient correlation was 0.99958, and the minimum detection concentration was 0.03 mg/m(3) (collected sample volume was 1.50 L). The within-run precisions were 1.08%-1.75% and the between-run precisions were 1.41%-2.52%. The desorption rates were 95.15%-99.91%. The samples could be stored at least 3 days at room temperature and 7 days at 4 ℃ without significant loss. Conclusion: The method has the advantages of good precision, high sensitivity and simple operation. It is suitable for the determination of 4-methyl-2-pentanol in the air of workplace.

Abstract
Aging, often considered a result of random cellular damage, can be accurately estimated using DNA methylation profiles, the foundation of pan-tissue epigenetic clocks. Here, we demonstrate the development of universal pan-mammalian clocks, using 11,754 methylation arrays from our Mammalian Methylation Consortium, which encompass 59 tissue types across 185 mammalian species. These predictive models estimate mammalian tissue age with high accuracy (r > 0.96). Age deviations correlate with human mortality risk, mouse somatotropic axis mutations and caloric restriction. We identified specific cytosines with methylation levels that change with age across numerous species. These sites, highly enriched in polycomb repressive complex 2-binding locations, are near genes implicated in mammalian development, cancer, obesity and longevity. Our findings offer new evidence suggesting that aging is evolutionarily conserved and intertwined with developmental processes across all mammals.

Abstract
Objective: To evaluate the efficacy and safety of intravenous iron supplementation in patients with recurrent iron deficiency anemia (IDA) . Methods: This retrospective analysis of 90 patients with recurrent IDA from May 2012 to December 2021 was conducted, comparing the efficacy and safety of the intravenous iron therapy group and the oral iron therapy group. Results: Among the 90 patients with recurrent IDA, 20 were males and 70 were females, with a median age of 40 (range: 14-85) years. A total of 60 patients received intravenous iron supplementation and 30 received oral iron supplementation. The hematologic response rates in the intravenous iron group were significantly higher than those in the oral iron group at 4 and 8 weeks after treatment [80.0% (48/60) vs 3.3% (1/30) and 96.7% (58/60) vs 46.7% (14/30), all P<0.001, respectively]. The median increase in hemoglobin levels was also significantly higher in the intravenous iron group than in the oral iron group [38 (4, 66) g/L vs 7 (1, 22) g/L at week 4 and 44.5 (18, 80) g/L vs 19 (3, 53) g/L at week 8, all P<0.001]. The intravenous iron group had a significantly higher proportion of patients who achieved normal hemoglobin levels than the oral iron group (55.0% vs 0 and 90% vs 43.3%, all P<0.001, respectively). Iron metabolism indicators were tested before and after 8 weeks of treatment in 26 and 7 patients in the intravenous and oral iron groups, respectively. The median increase in serum ferritin (SF) levels in the intravenous iron group 8 weeks after treatment was 113.7 (49.7, 413.5) μg/L, and 54% (14/26) of these patients had SF levels of ≥100 μg/L, which was significantly higher than the median increase in SF levels in the oral iron group [14.0 (5.8, 84.2) μg/L, t=4.760, P<0.001] and the proportion of patients with SF levels of ≥100 μg/L (P=0.013). The incidence of adverse reactions was 3.3% (2/60) in the intravenous iron group, which was significantly lower than that in the oral iron group [20.0% (6/30), P=0.015]. Conclusion: Intravenous iron supplementation is more effective for hematologic response, faster hemoglobin increase, and higher iron storage replenishment rates compared with oral iron supplementation in patients with recurrent IDA, and it is well tolerated by patients.

Abstract
Objective: To investigate the effect of on-demand glucocorticoid strategy on the occurrence and outcome of porcine anti-lymphocyte globulin (p-ALG) -associated serum sickness in aplastic anemia (AA) . Methods: The data of AA patients who received in the Anemia Diagnosis and Treatment Center of Haematology Hospital, CAMS & PUMC from January 2019 to January 2022 were collected. Among them, 35 patients were enrolled in the on-demand group, with the glucocorticoid strategy adjusted based on the occurrence and severity of serum sickness; 105 patients were recruited in the usual group by matching the age and disease diagnosis according to 1∶3 ratio in patients who received a conventional glucocorticoid strategy in the same period. The incidences, clinical manifestations, treatment outcomes of serum sickness, and glucocorticoid dosage between the two groups were analyzed. Results: The incidences of serum sickness in the on-demand group and the usual group were 65.7% and 54.3% (P=0.237) , respectively. The median onset of serum sickness was the same [12 (9, 13) d vs the 12 (10, 13) d, P=0.552], and clinical symptoms and signs, primarily joint, and/or muscle pain, fever, and rash were similar. Severity grades were both dominated by Grades 1-2 (62.8% vs 51.4%) , with only a few Grade 3 (2.9% vs 2.9%) , and no Grades 4-5. No significant difference in the serum sickness distribution (P=0.530) . The median duration of serum sickness was the same [5 (3, 7) d vs 5 (3, 6) d, P=0.529], and all patients were completely cured after glucocorticoid therapy. In patients without serum sickness, the average dosage of prophylactic glucocorticoid per patient in the usual group was (469.48 ±193.57) mg (0 in the on-demand group) . When compared to the usual group, the average therapeutic glucocorticoid dosage per patient in the on-demand group was significantly lower [ (125.91±77.70) mg vs (653.90±285.56) mg, P<0.001]. Conclusions: In comparison to the usual glucocorticoid strategy, the on-demand treatment strategy could significantly reduce glucocorticoid dosage without increasing the incidence of serum sickness; in addition, the duration of serum sickness and the incidence of above Grade 2-serum sickness were similar.

Abstract
Objective: To investigate the effect of methylene blue tracing on the effect of surgical resection and the prognosis of gastric cancer patients in D2 radical surgery under laparoscope. Methods: In this retrospective cohort study, 160 patients with advanced gastric cancer who underwent surgical treatment in Xinxiang Central Hospital, the 4th Clinical College of Xinxiang Medical College from January 2016 to January 2019 were selected for retrospective analysis. Among them, 84 patients underwent laparoscopic D2 radical gastrectomy for gastric cancer combined with methylene blue labeling operation (labeling group), and the other 76 patients underwent only laparoscopic D2 radical gastrectomy for gastric cancer (control group). The difference of intraoperative and postoperative recovery, lymph node dissection, and postoperative 3-year cumulative survival rate between the two groups were analyzed. Results: The age of patients in the labeled group and the control group were (64.9±7.8) and (66.0±8.3) years old, respectively (P=0.389); And the male patients accounted for 61.9% (52 cases) and 55.3% (42 cases), respectively (P=0.394); The operation time in the labeled group was (218.5±19.6) min, which was shorter than that in the control group (230.1±17.4) min (P<0.001). There was no significant difference between the labeled group and the control group in the amount of bleeding during operation, the time of anal exhaust after operation, the time of eating after operation, the time of hospitalization after operation, and the average diameter of lymph nodes (P>0.05). The total number of dissected lymph nodes, D1 lymph nodes and D2 lymph nodes in the labeled group were significantly higher than those in the control group (all P values<0.05). The operative complication rate in the labeled group was 11.9% (10 cases), which was lower than that in the control group (25.0%, 19 cases) (P=0.032); There was no statistical significance in 3-year cumulative survival rates of patients between the labeled group (61.9%) and the control group (52.6%) (χ2=3.46,P=0.065). Conclusion: The use of methylene blue tracing in laparoscopic D2 radical surgery for gastric cancer is beneficial to reduce the operation time, improve the lymph node clearance rate, and reduce surgical complications.

Abstract
Objective: To investigate the effect of miR-369-3p targeting ACTN4 expression on proliferation and apoptosis of hepatocellular carcinoma cells. Methods: Real-time quantitative polymerase chain reaction (RT-qPCR) and western blot were used to detect the expression levels of miR-369-3p and ACTN4 in hepatocarcinoma tissues and adjacent tissues. MiR-369-3p mimics, miR-negative control (NC), si-ACTN4, and si-NC were transfected into hepatocellular carcinoma MHCC97H cells by liposome method. Cell proliferation was detected by 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-dipheny-ltetrazolium bromide (MTT) assay. Flow cytometry was used to detect cell cycle and apoptotic rates. The dual luciferase reporter assay was used to verify the targeted regulation of ACTN4 by miR-369-3p. Western blot was used to detect the expressions of cyclin D1, p21, Bcl-2 and Bax. Results: The expression level of miR-369-3p in liver cancer tissue was lower than that in adjacent tissues [(0.46±0.04) vs (1.00±0.08), P<0.001)], while the expression level of ACTN4 was higher than that in adjacent tissues [mRNA (3.12±0.29) vs (1.01±0.09); protein (0.61±0.06) vs (0.25±0.03), P<0.001]. Overexpression of miR-369-3p significantly decreased the cell viability[(0.71±0.06) vs (1.26±0.11), P<0.001)], increased cell apoptosis rate [(20.16±2.11)% vs (6.25±0.64)%, P<0.001], increased the proportion of cells in G(1) phase [(31.14±3.36)% vs (51.56±5.23)%, P<0.001], decreased the proportion of cells in S phase [(32.44±3.56)% vs (14.33) ±1.45)%, P<0.001], increased the levels of p21 and Bax protein (P<0.001), and decreased the levels of cyclin D1 and Bcl-2 protein (P<0.001). Inhibition of the expression of ACTN4 significantly reduced the cell viability [(0.78±0.07) vs (1.24±0.12), P<0.001], increased the apoptosis rate [(6.58±0.66)% vs (18.32±1.82)%, P<0.001], increased the proportion of cells in G(1) phase [(48.69±4.21)% vs (30.33±3.01)%, P<0.001], decreased the proportion of cells in S phase [(36.21±3.42)% vs (18.54±1.61)%, P<0.001], increased the protein levels of p21 and Bax (P<0.001), and decreased the levels of cyclin D1 and Bcl-2 protein (P<0.001). Compared with the miR-369-3p+ pcDNA group, overexpression of ACTN4 increased the proliferation ability of hepatocellular carcinoma MHCC97H cells at 72 hours of culture[(1.12±0.11) vs (0.68±0.06), P<0.001], significantly reduced the proportion of cells in G(1) stage [(38.81±3.24)% vs (51.80±4.57)%, P<0.001], significantly increased the proportion of S-phase cells [(31.65±3.11)% vs (15.69±1.44)%, P<0.001], decreased cell apoptosis rate [(13.86±1.37)% vs (22.69±2.24)%, P<0.001], increased protein expressions of cyclin D1 and Bcl-2 (P<0.001), decreased the protein expressions of p21 and Bax (P<0.001). Conclusion: MiR-369-3p can induce cell cycle arrest in G(1) phase, inhibit the proliferation and promote apoptosis of liver cancer cells by regulating the expression of ACTN4.

Abstract
Except for a few stick insects that are economically valuable, most species be considered to be forest pests, so it is extremely important to obtain plant host-use information of more stick insects. In this paper, the plant hosts of three species of stick insects were recorded for the first time. We also discovered these stick insects can feed upon the flowers or leaves of plants. Lopaphus unidentatus (Chen & He, 1995) (Phasmida: Lonchodidae) attacked Hypericum choisianum Wall. ex N. Robson, 1973 (Hypericaceae), Leurophasma dolichocercum Bi, 1995 (Phasmida: Aschiphasmatidae) attacked Antenoron filiforme (Thunb.) Roberty & Vautier, 1964 (Polygonaceae) and Megalophasma granulatum Bi, 1995 (Phasmida: Lonchodidae) attacked Debregeasia orientalis C. J. Chen, 1991 (Urticaceae). Finally, we were lucky enough to also obtain photographs of them mating and feeding.

Abstract
Objective: To study the effect of iron deficiency level for oral iron absorption in iron deficient patients. Methods: 37 non-pregnant female patients who were diagnosed with iron deficiency and 13 healthy females who completed their physical examination at the outpatient department of the Anemia Center of the Institute of Hematology & Blood Diseases Hospital from July 2018 to June 2020 were included. Hepcidin and C2-C0 of oral iron absorption test were analyzed in different iron deficiency and serum ferritin level. Results: The median of Hepcidin in IDA, ID/IDE and healthy control group were 4.9 (2.17-32.86) , 26.98 (11.02-49.71) and 69.89 (42.23-138.96) μg/L (P<0.001) , respectively. Hepcidin level of IDA group was lower than that of ID/IDE group (adjusted P=0.005) and healthy control (adjusted P<0.001) . Hepcidin level of ID/IDE group had no significant difference compared with healthy control (adjusted P=0.22) . The mean of C2-C0 in IDA, ID/IDE and healthy control group were (35.30±21.68) , (37.90±14.06) and (23.57±10.14) μmol/L (P=0.130) , respectively. Multilinear regression analysis showed C0, SF, sTFR and HGB were independent factors for Hepcidin in iron deficient patients, with an equation of Hepcidin=-31.842-0.642*C0+2.239*SF+1.778*sTFR+0.365*HGB-0.274*RET-HB. We didn't find independent factor of C2-C0. Conclusion: The degree of iron deficiency had an effect on oral iron absorption. Patients of ID/IDE group absorbed iron more slowly than patients of IDA group. Iron deficient patients with normal gastrointestinal function absorbed more iron by oral administration when they were in a more serious iron deficient stage. Hepcidin was a better parameter to distinguish iron absorption level among different iron deficient patients than C2-C0 of oral iron absorption test.

Abstract
Objective: To investigate the efficacy and safety of the recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein (rhTNFR: Fc, etanercept) for the treatment of occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) . Methods: In September 2011 to February 2016, 12 patients with OMLDT were treated with etanercept 25 mg, subcutaneous injection, twice per week, doubling of first dose. The course of treatment was 6 weeks. The drug eruption area and severity index (DASI) score, the proportion of patients achieving a 50%, 75% and 90% reduction in DASI (DASI50, DASI75, DASI90) and the serum level of TNF-α were used to assess the efficacy at different times. Adverse reactions were also recorded and evaluated. The results were statistically analyzed by nonparametric Friedman test and repetitive measurement ANOVA using the software SPSS19.0. Results: After 4 weeks treatment, the DASI score decreased form 56.33±7.02 to 0.50±0.91 (P<0.01) . The DASI50, DASI75 and DASI90 were all increased to 12 (100%) . The serum level of TNF-α decreased form (43.74±41.62) pg/ml to (3.03±0.47) pg/ml (P<0.01) . Statistically significant difference was observed from the above indexes. There were no adverse reactions in clinical application. Conclusion: Recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein may be a safe and effective drug in the treatment of OMLDT.

Abstract
OBJECTIVE To compare and analyze the clinical effects of arthroscopic therapy and drug therapy in treating anterior cruciate ligament (ACL) rupture with secondary osteoarthritis (OA). PATIENTS AND METHODS A total of 68 patients that were diagnosed as ACL rupture with secondary OA in our hospital from February 2014 to February 2015 were enrolled in our study. All of the patients were randomly divided into control group (n = 30) and observation group (n = 38) according to the order of admission. The patients in the control group were given analgesic, anti-inflammatory drugs + functional rehabilitation training whereas the patients in the observation group were given ACL reconstruction + OA debridement and functional rehabilitation training under arthroscopy. RESULTS The success rate of the observation group was 92.1%. After 3-month follow-up, the clinical total effective rate of the observation group was significantly higher than that of the control group, the prevalence of complications in the observation group was significantly lower than in the control group, and differences were statistically significant (p < 0.05). Lysholm scale scoring of observation group was significantly higher than of the control group, modified McGill pain scale score was significantly lower than that of the control group, and differences were statistically significant (p < 0.05). Quadriceps muscle peak torque, average power, and the optimal single work at 60°/s, 120°/s, and 180°/s were significantly higher than those of the control group, and differences were statistically significant (p < 0.05). CONCLUSIONS Arthroscopic operative therapy was safe and effective for the treatment of ACL with secondary OA. Compared with drug therapy, it can significantly improve the movement function of the knee joint, so it was worthy of clinical application.

Abstract
In this study, iron reduction and concomitant biomineralization of a deep-sea iron reducing bacterium (IRB), Shewanella piezotolerans WP3, were systematically examined at different hydrostatic pressures (0.1, 5, 20, and 50 MPa). Our results indicate that bacterial iron reduction and induced biomineralization are influenced by hydrostatic pressure. Specifically, the iron reduction rate and extent consistently decreases with the increase in hydrostatic pressure. By extrapolation, the iron reduction rate should drop to zero by ~68 MPa, which suggests a possible shut-off of enzymatic iron reduction of WP3 at this pressure. Nano-sized superparamagnetic magnetite minerals are formed under all the experimental pressures; nevertheless, even as magnetite production decreases, the crystallinity and grain size of magnetite minerals increase at higher pressure. These results imply that IRB may play an important role in iron reduction, biomineralization, and biogeochemical cycling in deep-sea environments.

Abstract
BACKGROUND no systematic studies on the prevalence of coeliac disease (CD) have been reported from China. In western populations CD is more common in patients with insulin dependent diabetes mellitus (IDDM) and in diarrhoea-predominant irritable bowel syndrome (D-IBS). We have screened patients with these conditions presenting to the outpatient department of a large hospital of "Traditional Chinese Medicine" (TCM) in Nanjing, Jiangsu province, P.R. China. METHODS we tested sera of 78 unrelated Han Chinese patients (5 IDDM and 73 D-IBS), using ELISA serological tests for IgG anti-gliadin antibodies (IgG-AGA) and IgA anti-tissue transglutaminase antibodies (IgA-tTG). RESULTS six out of 78 patients (7.7%) were positive for IgG-AGA (two men and four women) and two (2.6%) were positive for IgA-tTGs. One of the latter patients was negative for IgG-AGA. Besides, one patient had a dubious IgA-tTG antibody and a positive IgG-AGA. None of the six patients agreed to undergo duodenal biopsy. Two out of these six patients followed a gluten-free diet for one year. In one patient the diarrhoea ceased and his body weight increased. Another stopped losing weight. CONCLUSIONS this study previously published as a letter in GUT (Wu J, Xia B, von Blomberg BME, Zhao C, Yang XW, Crusius JBA, Peña AS. Coeliac disease: emerging in China? Gut 2010; 59(3): 418-9) demonstrated that CD may exist in the Jiangsu province of P.R. China. The present article draws attention to the difficulties of following a standard protocol in China such as established in western countries and highlights important factors less well known in the west in relation to the development of CD in China. Wheat production became significant in China between 1600 and 1300 B.C. After the Han dynasty (500-200 B.C.), wheat was one of the main cereals in China. One the major wheat fields in China is located in the Jiangsu province where the research for this article was performed. A review of Chinese literature shows that the predominant HLA-DQ CD risk alleles and haplotypes are present in the Jiangsu province. Genetic background, food consumption, and the results of our study suggest that CD should actively be investigated in P.R. China.

Abstract
Huntington's disease (HD) is a neurodegenerative disorder caused by a polyglutamine repeat expansion in huntingtin. A newly developed bacterial artificial chromosome transgenic mouse model (BACHD) reproduces phenotypic features of HD including predominantly neuropil-associated protein aggregation and progressive motor dysfunction with selective neurodegenerative pathology. Motor dysfunction has been shown to precede neuropathology in BACHD mice. We therefore investigated the progression of synaptic pathology in pyramidal cells and interneurons of the superficial motor cortex of BACHD mice. Whole-cell patch clamp recordings were performed on layer 2/3 primary motor cortical pyramidal cells and parvalbumin interneurons from BACHD mice at 3 months, when the mice begin to demonstrate mild motor dysfunction, and at 6 months, when the motor dysfunction is more severe. Changes in synaptic variances were detectable at 3 months, and at 6 months BACHD mice display progressive synaptic pathology in the form of reduced cortical excitation and loss of inhibition onto pyramidal cells. These results suggest that progressive alterations of the superficial cortical circuitry may contribute to the decline of motor function in BACHD mice. The synaptic pathology occurs prior to neuronal degeneration and may therefore prove useful as a target for future therapeutic design.

Abstract
The ternary solid complexes RE(Et2dtc)3 (phen) (RE=La, Pr, Nd, Sm-Er) were synthesized with sodium diethyldithiocarbamate (NaEt2 dtc x 3H2O), 1,10-phenanthroline (o-phen x H2O) and hydrated lanthanide chlorides in absolute ethanol by improved reported method. IR results revealed that RE3+ coordinated with sulfur atoms of NaEt2 dtc and nitrogen atoms of o-phen. As for UV spectrum of the complexes, energy transfer between o-phen and RE3+ was the primary process, and the main absorption peaks showed a slight red shift compared to that of o-phen; FS spectrum, as a comparison, showed that the complexes Sm (Et2 dtc)3 (phen) and Eu(Et2dtc)3 (phen) have a higher efficiency of intermolecular energy transfer and a stronger fluorescence character.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) such as acetylsalicylic acid (ASA, aspirin) are well known chemotherapeutic agents of cancers; however, the signalling molecules involved remain unclear. The aim of this study was to investigate the possible existence of a putative p53-dependent pathway underlying the ASA-induced apoptosis in OC2 cells, a human oral cancer cell line. MATERIALS AND METHODS The methyl tetrazolium (MTT) assay was employed to quantify differences in cell viability. DNA ladder formation on agarose electrophoresis was used as apoptosis assay. The expression levels of several master regulatory molecules controlling various signal pathways were monitored using the immunoblotting techniques. Flow cytometry was used to confirm the effect of ASA on cell cycle. Patterns of changes in expression were scanned and analyzed using the NIH image 1.56 software (NIH, Bethesda, MD, USA). All the data were analyzed by ANOVA. RESULTS Acetylsalicylic acid reduced cell viability and presence of internucleosomal DNA fragmentation. In the meanwhile, phosphorylation of p53 at serine 15, accumulation of p53 and increased the expression of its downstream target genes, p21 and Bax induced by ASA. The expression of cyclooxygenase-2 was suppressed. Disruption of p53-murine double minute-2 (MDM2) complex formation resulted in increasing the expression of MDM2 60-kDa cleavage fragment. Inhibited the activation of p42/p44 mitogen-activated protein kinase (MAPK) by PD98059, a specific inhibitor of extracellular regulatory kinase (ERK), significantly decreased cell viability and enhanced the expression of p53 induced by ASA. The result of the cell-cycle analysis showed that ASA and PD98059 induced the cell cycle arrested at the G0/G1 phase and resulted in apoptosis. CONCLUSION Nonsteroidal anti-inflammatory drug-inhibited cyclooxygenase is not the only or even the most important mechanism of inhibition. Our study presents evidences that activation of p53 signalling involved in apoptosis induced by ASA. Furthermore, the apoptotic effect was enhanced by blocking the activation of p42/p44 MAPK in response to treatment with ASA, thus indicating a negative role for p42/p44 MAPK.

Abstract
Modification of bacterial artificial chromosomes (BACs) has been a useful method to produce genomic DNA fragments for studying gene expression and function in vitro and in vivo. The original technique involved restrictions for BAC modification and required multiple cloning steps to target sequences into the shuttle vector. Selection and screening of BAC recombinants was accomplished by drug resistance and Southern blotting. We have developed a PCR-based method for producing the modified shuttle vectors and for screening for BACs carrying homologous integrants. The combination of these techniques allows for rapid and easy targeted BAC sequence deletion or insertion.

Abstract
Genetic analysis in mice has most commonly employed two general strategies: phenotypic screens for spontaneous or induced mutations and genotypic analysis using homologous recombination or gene trapping to produce deletion or insertion mutants. Here we use bacterial artificial chromosome (BAC)-mediated gene-dosage analysis in transgenic mice to reveal novel genetic functions that are not evident from conventional loss-of-function mutations. We demonstrate a role for the zinc-finger transcription factor Zipro1 (formerly Ru49 and Zfp38) in the proliferation of granule cell precursors in the developing cerebellum, and document the contribution of this process to the final stages of cerebellar morphogenesis. We also show that Zipro1 is expressed in skin, and increased Zipro1 dosage results in a hair-loss phenotype associated with increased epithelial cell proliferation and abnormal hair follicle development.

Abstract
Escherichia coli-based artificial chromosomes have become important tools for physical mapping and sequencing in various genome projects. The lack of a general method to modify these large bacterial clones, however, has limited their utility in functional studies. We developed a simple method to modify bacterial artificial chromosomes directly in the recombination-deficient E. coli host strain by homologous recombination for in vivo studies. The IRES-LacZ marker gene was introduced into a 131 kb BAC containing the murine zinc finger gene, RU49. No rearrangements or deletions were detected in the modified BACs. Furthermore, transgenic mice were generated by pronuclear injection of the modified BAC, and germline transmission of the intact BAC has been obtained. Proper expression of the lacZ transgene in the brain has been observed, which could not be obtained with conventional transgenic constructs.

Abstract
The creation of specific neuronal cell types within the developing brain is a critical and unsolved biological problem. Precedent from invertebrate development, and from vertebrate myogenesis and lymphogenesis, has established that cell specification often involves transcription factors that are expressed throughout the differentiation of a given cell type. In this study, we have identified in Zn2+ finger transcription factor RU49 as a definitive marker for the cerebellar granule neuron lineage. Thus, RU49 is expressed in the earliest granule cell progenitors at the rhombic lip as they separate from the ventricular zone of the neural tube to generate a secondary proliferative matrix, and it continues to be expressed in differentiating and mature granule neurons. Proliferating granule cell progenitors isolated from the rhombic lip at E14 or from the external germinal layer at P6 continue to express RU49 in vitro. Both the olfactory bulb and dentate gyrus granule cell lineages also express this factor as they are generated with the developing brain. RU49 binds a novel bipartite DNA-binding element in a manner consistent with chemical rules governing the DNA-binding specificity of this class of transcription factor. The novel biochemical properties of RU49 and its restricted expression within the three lineages of CNS granule neurons suggest that RU49 may play a critical role in their specification. Furthermore, these results raise the interesting possibility that the generation of these three neuronal populations to form displaced germinative zones within the developing brain may reflect their use of a common developmental mechanism involving RU49.

Abstract
AIM To study the photosensitization of dicoumarol (Dic) on tumor cells and any effect by sodium diethyldithiocarbamate (DDC). RESULTS Dic, 40, 80, 120 mumol.L-1 concentration-dependently inhibited the DNA synthesis (81%-93%) and increased the mortality (50%-70.4%) of ascitic hepatoma (Hep A) cells exposed in light. These 2 indices were changed slightly by Dic alone even in non-illuminating group. DDC enhanced the photosensitization of Dic group. CONCLUSION Photosensitization of Dic showed strong antitumor activities against Hep A cells. The mortality of Hep A and inhibition of the DNA synthesis in Dic-DDC-light group significantly stronger than in Dic-light group. Photosensitization of Dic was not due to 1O2 and OH., but closely related to O2.- and H2O2.

Abstract
10 patients who received sagittal split ramus osteotomy for advance the mandible were examined clinically and radiographically to assess condylar position preoperatively and six months postoperatively. The results showed after surgery maximal interincisal opening was significantly reduced; anterior, upper, posterior space of temporomandibular joint were changed; 14/20 condyles were relatively retropositioned; and 6/20 condyles were relatively forward positioned. Alteration in condylar position may undergo adjustment and remodeling in order to adapt the new position in most patients. In some patients symptoms and signs of the joint disappear following changing of condylar position.

Abstract
Export to the cytoplasm of U3 RNA transcribed from a rat U3 gene injected into the nucleus of Xenopus oocytes indicates that the biogenesis of U3 RNA, like that of the previously studied Sm-precipitable nucleoplasmic snRNAs (U1, U2, U4, and U5), includes a cytoplasmic phase. The regulation of import of the U3 snRNA into the nucleus has been analyzed by injection of synthetic human U3 transcripts into the cytoplasm of Xenopus oocytes. Binding of the major autoantigenic protein of the U3 snRNP, fibrillarin, and cap trimethylation can occur in the cytoplasm, but neither are required for import. The 3'-terminal 13 nucleotides are required for optimal import and cap trimethylation and participate in a phylogenetically conserved U3 structural element, a short 3'-terminal stem. An artificial construct containing the 3'-terminal 13 nucleotides, including the 3'-terminal stem, but only 56 nucleotides of the 217 nucleotides in U3, appears to be sufficient for import. The presence of the 3'-terminal stem in all snRNAs known to be imported suggests that it might be a universal element required for nuclear import.

Abstract
Three-days successive p.o. administration of an EtOH extract of the stems of Kadsura heteroclita (Schizandraceae) or its major constituent, kadsurin, resulted in significant decreases of CCl4-induced lipid-peroxidation products, such as thiobarbituric acid reactive substances (TBA-RS), conjugated dienes and fluorescent products in the liver of mice. In contrast, a significant restoration of superoxide dismutase (SOD) activity reduced by CCl4-intoxication was observed in the administered groups, suggesting that the subchronic treatment of mice with the EtOH extract or kadsurin induce enzymes capable of scavenging oxygen radical species in the liver, though the extract and kadsurin themselves may have an anti-oxidant property.

Abstract
From the ether extract of the underground part of Notopterygium forbesii, two new coumarin glycosides, bergaptol-O-beta-D-glucopyranoside and 6'-O-trans-feruloylnodakenin, were isolated along with known compounds including seven furanocoumarins, two dihydrofuranocoumarins, a sterol glucoside and two phenolic compounds. Analysis of their contents by high-performance liquid chromatography (HPLC) revealed that the underground part of N. forbesii contained large amounts of p-hydroxphenethyl anisate (0.7%), bergaptol glucoside (0.2%), nodakenin (2%) and 6'-O-trans-feruloylnodakenin (0.7%) and a lesser amount of notopterol (0.08%), while that of N. incisum contained a large amount of notopterol (1.2%) and less amounts of the others. The characteristic difference in chemical composition between the two species enabled us to identify the respective botanical sources of a Chinese crude drug, Qiang-huo derived from N. incisum and N. forbesii by HPLC.

Abstract
Analytical and experimental methods are provided for estimating synaptic connectivities from simultaneous recordings of multiple neurons. The results are based on detailed, yet flexible neuron models in which spike trains are modeled as general doubly stochastic point processes. The expressions derived can be used with nonstationary or stationary records, and can be readily extended from pairwise to multineuron estimates. Furthermore, we show analytically how the estimates are improved as more neurons are sampled, and derive the appropriate normalizations to eliminate stimulus-related correlations. Finally, we illustrate the use and interpretation of the analytical expressions on simulated spike trains and neural networks, and give explicit confidence measures on the estimates.

Abstract
The results of determination of serum alpha-L-fucosidase (AFU) in healthy individuals, in patients with various liver diseases and non-liver malignant diseases were reported. In primary hepatic carcinoma the level of serum AFU was significantly higher than that in various other diseases and healthy persons (P less than 0.001). The serum AFU level was independent of AFP level (x = 1.24, P greater than 0.25). These data suggest that AFU may be a useful marker for the diagnosis of primary hepato cellular carcinoam with negative AFP.

Abstract
The red cell C3b receptor activity of 52 patients with esophageal cancer, 19 patients with cancer of gastric cardia and 31 age-matched normal persons was studied by the ability of forming ZC3b-rosette (rosette formation with zymosan particles treated by guinea pig complement) and IC-Z rosette (rosette formation with zymosan particles). The results showed that the ZC3b-rosette formation rate was significantly lower in cancer patients than that of the normal subjects (P less than 0.01), but the IC-Z rosette formation rate was significantly higher in the cancer patients (P less than 0.01). This suggests that the esophageal cancer and cancer of gastric cardia be associated with surface changes in the erythrocytes, especially those of the receptors which are responsible for immune adherence reaction. The methods of detecting the red cell C3b receptor are also described.
