Abstract
Objective: To understand the knowledge, attitude and behavior of adult residents on influenza, pneumococcus, human papillomavirus (HPV), herpes zoster (HZ), COVID-19, hepatitis B and rabies vaccination in Shandong Province. Methods: From August to September 2022, a multi-stage stratified random sampling method was used to investigate community-dwelling residents aged 18 years old and above in 12 counties (cities and districts) of Shandong Province. A questionnaire survey was used to collect the basic information of the respondents, such as knowledge, attitude and vaccination behavior of influenza, pneumococcus, HPV, HZ, COVID-19, hepatitis B and rabies vaccine. Analysis of variance was used to compare the differences in the respondents' knowledge and attitude scores of different vaccines. The Chi-square test was conducted to compare the differences in vaccination reasons among different characteristics, and a logistic regression model was used to analyze the influencing factors of vaccination behavior. Results: The median age (Q1, Q3) of the 2 754 respondents was 39 (29, 57) years ranging from 18 to 94 years, with a number of 1 234 (44.81%) males. The average score of the respondents' understanding of various knowledge about adult vaccines was less than 4 points, with the highest score for understanding which diseases can be prevented by adult vaccines. The average score of consent and necessity for adult vaccines to prevent diseases was greater than 3.6 points. In terms of knowledge demand and trust in information channels, there was a high level of trust in the recommendations of vaccination outpatient staff and clinical doctors [with scores of (4.15±0.79) and (4.02±0.80), respectively]. The highest demand for information on vaccination safety knowledge was (4.18±0.84) points. In recent two years, 52.11% of the population had been vaccinated with other vaccines in addition to the COVID-19 vaccine and rabies vaccine, and 45.44% of the population felt it was necessary to be vaccinated through media publicity. Women, age growth, high education level, and high-income level were the promoting factors for adopting vaccination behavior. Conclusion: Adult residents in Shandong Province have a basic understanding and supportive attitude towards vaccination, but the vaccination behavior rate is still relatively low, with significant differences in sex, age, education level, and income level. It is necessary to further increase efforts in the breadth and depth of adult vaccination promotion and education, as well as promotion strategies targeting different populations.

Abstract
To reduce the harmful effects of nicosulfuron on sweet corn, the physiological regulation mechanism of sweet corn detoxification was studied. This study analyzed the effects of nicosulfuron stress on the glyoxalase system, hormone content, and key gene expression of nicosulfuron-tolerant "HK301" and nicosulfuron-sensitive "HK320" sweet corn seedling sister lines. After spraying nicosulfuron, the methylglyoxal (MG) content in HK301 increased first and then decreased. Glyoxalase I (GlyI) and glyoxalase II (GlyII) activities, non-enzymatic glutathione (GSH), and the glutathione redox state glutathione/(glutathione + glutathione disulfide) (GSH/(GSH + GSSG)) showed a similar trend as the MG content. Abscisic acid (ABA), gibberellin (GA), and zeatin nucleoside (ZR) also increased first and then decreased, whereas the auxin (IAA) increased continuously. In HK301, all indices after spraying nicosulfuron were significantly greater than those of the control. In HK320, MG accumulation continued to increase after nicosulfuron spraying and GlyI and GlyII activities, and GSH first increased and then decreased after 1 day of stress. The indicators above were significantly greater than the control. The GSH/(GSH + GSSG) ratio showed a decreasing trend and was significantly smaller than the control. Furthermore, ABA and IAA continued to increase, and the GA and ZR first increased and then decreased. Compared with HK320, HK301 significantly upregulated the transcription levels of GlyI and GlyII genes in roots, stems, and leaves. Comprehensive analysis showed that sweet maize seedlings improved their herbicide resistance by changing the glyoxalase system and regulating endogenous hormones. The results provide a theoretical basis for further understanding the response mechanism of the glyoxalase system and the regulation characteristics of endogenous hormones in maize under nicosulfuron stress.

Abstract
Objective: To compare the efficacy and safety of venetoclax (VEN) combined with azacitidine (AZA) versus CAG regimen combined with decitabine (DAC) in elderly patients with relapsed acute myeloid leukemia (AML). Methods: From January 2018 to August 2020, the clinical data of forty-five elderly patients with relapse AML at the First Affiliated Hospital of Soochow University were retrospectively analyzed, including 31 males and 14 females. The median age was 66 (60-80) years old. Eighteen patients were administrated with VEN and AZA, while the other 27 were in CAG with DAC. The complete remission (CR) rate, partial remission (PR) rate, total remission rate (ORR), adverse events and overall survival (OS) were compared between the two groups. Results: At the end of the treatment, the ORR in VEN with AZA group was 77.8% (14/18); including 11 CR and 3 PR. In CAG with DAC group, the ORR was 37.0% (10/27); including 8 CR and 2 PR (P=0.007). Subgroup analysis suggested that VEN with AZA had a higher ORR in patients stratified as intermediate and poor-risk (P=0.013) or with DNA methylation mutations (P=0.007). Main adverse events in both groups were bone marrow suppression, infections, nausea and vomiting, anorexia and fatigue. Grade Ⅲ-Ⅳ cytopenia developed in lower incidence of VEN with AZA group, such as leukopenia (66.7% vs. 100%, P=0.002), anemia (50.0% vs. 92.6%, P=0.002), thrombocytopenia (72.2% vs. 96.3%, P=0.031) and neutropenia (61.1% vs. 92.6%, P=0.014). In addition, less grade Ⅲ-Ⅳ infections occurred in VEN with AZA group (66.7% vs. 33.3%, P=0.028), as well as grade Ⅲ-Ⅳ gastrointestinal events (40.7% vs. 11.1%, P=0.032), grade Ⅲ-Ⅳ fatigue (55.6% vs.11.1%, P=0.003) compared with CAG with DAC group. The 1-year OS in VEN with AZA group versus CAG with DAC group was 42.9% and 31.6% respectively (P=0.150). Conclusion: VEN combined with AZA proves favorable efficacy and tolerablity in elderly patients with relapsed AML.

Abstract
Phosphatase and tensin homolog (PTEN) is a well-known tumor suppressor in nonruminants and regulates various cellular processes including growth through dephosphorylation of phosphoinositide substrates. Although studies with bovine mammary tissue suggested a role for PTEN during lactation, its potential role in lipid metabolism remains unknown. Objectives of the present study were to determine PTEN abundance in goat mammary tissue at 2 stages of lactation (n = 6 Xinong Saanen dairy goats per stage), and to use gene-silencing and adenoviral transfections in vitro with isolated goat mammary epithelial cells (GMEC) to evaluate the role of PTEN abundance of lipid metabolism-related genes. Abundance of PTEN decreased by 51.5% at peak lactation compared with the dry period. The PTEN was overexpressed in isolated GMEC through adenoviral transfection using an adenovirus system with Ad-GFP (recombinant adenovirus of green fluorescent protein) as control, and silenced via targeted small interfering RNA (siRNA) transfection with a scrambled small interfering RNA as a negative control. Cell culture was performed for 48 h before RNA extraction, triacylglycerol (TAG) analysis, and fatty acid analysis. Overexpression of PTEN downregulated abundance of acetyl-coenzyme A carboxylase α (ACACA), fatty acid synthase (FASN), sterol regulatory element binding transcription factor1 (SREBF1), stearoyl-coenzyme A desaturase 1 (SCD1), diacylglycerol acytransferase 1 (DGAT1), 1-acylglycerol-3-phosphate O-acyltransferase 6 (AGPAT6) coupled with an increase in patatin-like-phospholipase domain containing 2 (PNPLA2), hormone-sensitive lipase (LIPE), and carnitine palmitoyltransferase 1 β (CPT1B). Furthermore, overexpressing PTEN in vitro resulted in a significant decrease in TAG concentration and concentration of C16:1. In contrast, interference of PTEN led to an opposite effect on lipid metabolism in GMEC. These changes suggested a shift from lipogenesis and esterification to lipolysis and fatty acid oxidation. Collectively, PTEN seems to play a role in monounsaturated fatty acids synthesis and lipid accumulation in GMEC.

Abstract
AIM To investigate the accuracy of ultrasonography in the diagnosis of persistent sciatic artery (PSA) compared to computed tomography angiography (CTA). MATERIALS AND METHODS From May 2002 to Dec 2018, 61 consecutive patients seen at Shandong Medical Imaging Research Institute with a clinical suspicion of PSA were included. Ultrasonography was used to assess the abdominal and lower-limb arteries. The main sonographic criteria for a positive diagnosis were the visualisation of PSA, the enlarged internal iliac artery, and abnormality of common femoral artery and superficial femoral artery. These data were compared with CTA findings. Kappa statistics was applied to determine the level of agreement. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of ultrasonography as a diagnostic method were assessed. RESULTS Ultrasonography findings were positive in 16 of 61 patients with a clinical suspicion of PSA. The diagnosis was confirmed by CTA in 17 patients. There was one false-positive result and two false-negative results at ultrasonography. The kappa value was 0.875. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of ultrasonography were 88.2%, 97.7%, 93.8%, 95.6%, 95.1% and 0.859, respectively. CONCLUSIONS Ultrasonography could be a reliable, accurate, and non-invasive diagnostic imaging method in the diagnosis of patients with suspected PSA.

Abstract
Many microRNAs (miRNAs) exhibit altered expression levels in cancers, and they may be considered as valuable prognostic biomarkers for cancers. Here we aimed to summarize the recent advances in miR-10b involvement in human breast cancer and analyze the predicting role of miR-10b for survival. We searched, Embase, and Wanfang databases to identify studies on the prognostic role of miR-10b expression in breast cancer. A total of 770 patients from 7 eligible studies were included in the analysis. Pooled risk ratios (RRs) with 95% confidence interval (95%CI) were calculated to estimate the effect. Our results showed that high miR-10b expression in patients with breast cancer was significantly associated with poor disease-free survival (DFS) (RR = 1.53; 95%CI = 1.06-2.21; P = 0.02). However, no significant association between miR-10b and overall survival was found in overall studies. Subgroup analysis indicated that high expression of miR-10b was significantly correlated with DFS in Asia (RR = 2.94; 95%CI = 1.71-5.05). The present meta-analysis demonstrated that high expression of miR-10b might predict poor survival in patients with breast cancer. Larger clinical studies are required to further evaluate the role of miR-10b in clinical practice.

Abstract
A new ovarian cell line, CSO, was established from half-smooth tongue sole Cynoglossus semilaevis. Primary culture of CSO cells was initiated from digestion of ovarian tissues pieces by trypsin solution and cultured at 24° C in Dulbecco's modified Eagle's medium-F12 medium (DMEM-F12, 1:1) (pH 7·0), supplemented with 20% foetal bovine serum, basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), insulin-like growth factor-I (IGF-I) and human chorionic gonadotropin (HCG). The cultured CSO cells, fibroblastic in morphology, proliferated to 100% confluency 3 days later and had been subcultured to passage 80. Chromosome analyses indicated that the CSO cells exhibited chromosomal aneuploidy with a modal chromosome number of 42 that displayed the normal diploid karyotype of C. semilaevis [2n = 42 t, fundamental number (NF ) = 42]. Reverse transcription polymerase chain reaction revealed that CSO cells could express ovarian somatic cell functional genes p450armo, foxl2 and sox9a but not ovary germ cell marker gene vasa and male-specific gene dmrt1. Transfection experiment demonstrated that CSO cells transfected with pEGFP-N3 plasmid could express green fluorescence protein (GFP) with higher transfection efficiency. The CSO cell line might serve as a valuable tool for studies on the mechanism of sex determination and oogenesis of ovary in flatfish.

Abstract
AC98-6446 is a novel semisynthetic cyclic glycopeptide antibiotic related to the natural product mannopeptimycin alpha (AC98-1). In the present study the activity of AC98-6446 was evaluated against a variety of recent clinical gram-positive pathogens including multiply resistant strains. AC98-6446 demonstrated similar potent activities against methicillin-susceptible and methicillin-resistant staphylococci and glycopeptide-intermediate staphylococcal isolates (MICs at which 90% of isolates are inhibited [MIC(90)s], 0.03 to 0.06 microg/ml). AC98-6446 also demonstrated good activities against both vancomycin-resistant and -susceptible strains of enterococci (MIC(90)s, 0.12 and 0.25 microg/ml, respectively) as well as against streptococcal strains (MIC(90)s, <or= 0.008 to 0.03 microg/ml). AC98-6446 demonstrated bactericidal activity in terms of the reduction in the viable counts (>3 log(10) CFU/ml) of staphylococcal and streptococcal isolates and a marked decrease in the viable counts of most enterococcal strains (from 0.2 to 2.5 log(10) CFU/ml). Unlike vancomycin, which demonstrates time-dependent killing, AC98-6446 demonstrated concentration-dependent killing. The potent activity, novel structure, and bactericidal activity demonstrated by AC98-6446 make it an attractive candidate for further development.

Abstract
On-line concentration of neutral species of s-triazine herbicides in micellar electrokinetic chromatography using tetradecylammonium bromide (TTAB) as a cationic surfactant was investigated. Factors affecting the stacking of analytes were examined. The results indicate that the stacking efficiency is markedly improved with addition of phosphate buffer in the sample matrix. It was found that, depending on the nature of the analytes, the most effective stacking of these analytes occurs when the ratio of the conductivity of buffer electrolyte to that of sample matrix is in the range 1.4-1.2, with sample matrix containing phosphate buffer. Micelle concentration in the separation buffer is also a crucial factor to enhance the stacking efficiency and detection sensitivity of analytes. Moreover, the stacking efficiency of each individual analyte depends on its binding constant to TTAB micelles. The concentration effect is primarily based on sweeping mechanism which is operated in a normal stacking mode with reversed electrode polarity in the presence of reversed electroosmotic flow. As a result of concentration enhancement, the detection limits of these herbicides can reach about 9-15 ng/ml with UV detection.

Abstract
Chloro-s-triazines are difficult to separate by capillary zone electrophoresis (CZE), due to their low pKa values. However, these analytes can be effectively separated by CZE in the presence of cationic surfactant monomers, such as tetradecylammonium bromide (TTAB) and dodecyltrimethylammonium bromide (DTAB). The separation mechanism based on a 1:1 binding of analytes to cationic surfactant monomers is proposed. The binding constants of chloro-s-triazines to cationic surfactant monomers are estimated. The results show that the strength of the interactions of these analytes with TTAB monomers is considerably strong, whereas that of the corresponding analyte with DTAB monomers is about 12- to 14-fold weaker. A linear correlation of binding constants with log P(ow) (the logarithm of the partition coefficient of analytes between 1-octanol and aqueous phases) indicates that the migration order of these chloro-s-triazines depends primarily on their hydrophobicity. Moreover, the skewed peaks of chloro-s-triazines observed may reveal the occurrence of adsolubilization of these analytes in the adsorbed cationic surfactant layer on the capillary surface.

Abstract
The thermogenesis curves of the germination of different rice and tree seeds were determined and studied by using a newly constructed microcalorimeter. The thermogenesis curves of the germination of the seeds demonstrate the existence of physiological triphasic patterns, which include imbibition, activation and growth stages in the germination process. The thermodynamics and thermokinetics of the main growth phase of the growth stage in the germination process have been studied. The growth heat effect (deltaH), the growth rate constant (k), the growth inhibitory factor (s) and deceleration rate constant (beta) have been determined and calculated, In addition, the experimental thermokinetic equations of the growth stage in the seed germination process have been established.

Abstract
Two distinct calcitonin (CT) receptor (CTR)-encoding cDNAs (designated GC-2 and GC-10) were cloned and characterized from giant cell tumor of bone (GCT). Both GC-2 and GC-10 differ structurally from the human ovarian cell CTR (o-hCTR) that we cloned previously, but differ from each other only by the presence (GC-10) or absence (GC-2) of a predicted 16-amino acid insert in the putative first intracellular domain. Expression of all three CTR isoforms in COS cells demonstrated that GC-2 has a lower binding affinity for salmon (s) CT (Kd approximately 15 nM) than GC-10 or o-hCTR (Kd approximately 1.5 nM). Maximal stimulatory concentrations of CT resulted in a mean accumulation of cAMP in GC-2 transfected cells that was greater than eight times higher than in cells transfected with GC-10 after normalizing for the number of receptor-expressing cells. The marked difference in maximal cAMP response was also apparent after normalizing for receptor number. GC-2 also demonstrated a more potent ligand-mediated cAMP response compared with GC-10 for both human (h) and sCT (the EC50 values for GC-2 were approximately 0.2 nM for sCT and approximately 2 nM for hCT; EC50 values for GC-10 were approximately 6 nM for sCT and approximately 25 nM for hCT). Reverse transcriptase PCR of GCT RNA indicated that GC-2 transcripts are more abundant than those encoding for GC-10. In situ hybridization on GCT tissue sections demonstrated CTR mRNA expression in osteoclast-like cells. We localized the human CTR gene to chromosome 7 in band q22. The distinct functional characteristics of GC-2 and GC-10, which differ in structure only in the first intracellular domain, indicate that the first intracellular domain of the CTR plays a previously unidentified role in modulating ligand binding and signal transduction via the G protein/adenylate cyclase system.

Abstract
The present experiment is undertaken to study the mechanism of the inhibitory effect of 2-pyridylethylamine (PEA, i.c.v.) on the gastric acid secretion. Gastric acid was continuously washed out with 37 degrees C saline by means of a perfusion pump in Wistar rats weighing 200-300 g. Drugs were injected into the third ventricle to examine the effect on pentagastrin-induced (160 micrograms/kg, s.c.) gastric acid secretion. The results were as follows: (1) Pretreatment with naloxone (2.5 micrograms, i.c.v.) blocked the inhibitory effect of PEA (10 micrograms, i.c.v.) on gastric acid secretion. (2) The inhibitory effect of PEA (5-20 micrograms, i.c.v.) was turned into an excitatory effect after subdiaphragmatic vagotomy in a dose-dependent manner, but not changed by bilateral adrenalectomy. (3) In vagotomized rats, pretreatment with CRF-antiserum (1:20,000, 2.5 microliters, i.c.v.) or bilateral adrenalectomy abolished the excitatory effect of PEA (10 micrograms, i.c.v.). (4) PEA (10 micrograms, i.c.v.) did not change the basal gastric acid secretion in vagotomized rats. These results suggest that histamine H1-receptor in brain may be involved in both the inhibitory and excitatory regulation of gastric acid secretion mediated by vagus nerve and the hypothalamus-pituitary-adrenal axis.

Abstract
During 1986 and 1991, we had diagnosed 12 cases with genetic leukodystrophy including 9 cases with metachromatic leukodystrophy (MLD), 1 case with globoid cell leukodystrophy (GLD, Krabbe's disease), 1 case with neonatal adrenoleukodystrophy (NALD), and the other with probable Pelizaeus-Merzbacher disease (P-M disease). The clinical, biochemical, neurophysiological and neuroradiological features were reported. The diagnosis of MLD, GLD, NALD was confirmed by means of the measurement of serum arylsulfatase A activity, leukocyte galactocerebrosidase activity and serum very long chain fatty acids, respectively. The P-M disease was highly suspected according to clinical picture and evoked potential findings. All the brainstem auditary evoked potentials (BAEPs) and the scalp somatosensory evoked potentials (scalp SEPs) studies in 6 patients with MLD, 1 patient with GLD and 1 patient with NALD were abnormal. In patients with MLD or GLD, the nerve conduction velocity (NCV) studies showed moderate to severe slowing suggesting peripheral demyelinating neuropathy. Brain CT in patients with MLD or NALD demonstrated marked lucency in the white matter. Brain CTs in the patient with GLD showed progressive brain atrophy. In conclusion, though final diagnosis of genetic leukodystrophy should be established throughout biochemical studies, the neurophysiological and neuroimaging studies are of value as an aid to early diagnosis, prediction of clinical course and evaluation of prognosis for genetic leukodystrophy.

Abstract
Tu-er-feng is one of famous Chinese folk medicines in Sichuan prov. for common cold with cough, rheumatism, etc. Its sources are said to be either whole plants of some Gerbera or Ainsliaea species of family Compositae. In the recent markets, two types of Tu-er-feng are surely available. In this paper, Tu-er-feng derived from Gerbera species are studied to clarify the botanical origin; comparing mainly with the internal morphologies of the leaves and roots of G. piloselloides, G. delavayi, G. nivea, G. anandria (= Leibnitzia anandria) and G. jamesonii. As the result, G. piloselloides is determined as the botanical origin of Tu-er-feng obtained from the recent 16 markets.
