Abstract
Objective: To establish reference values for carotid intima-media thickness (CIMT) of adult dwellers in Shenzhen City. Methods: The study was conducted based on the Shenzhen heart failure epidemiological survey from 2021 to 2022. In this survey, residents aged 18 years and above in Shenzhen were selected by using a multi-stage stratified random sampling method. General information, cardiovascular disease (CVD) related behavior and carotid ultrasound examination and etc. were collected from the participants. People with CVD factors, a history of atherosclerotic cardiovascular disease, carotid plaque or having no carotid ultrasound examination results were excluded. The parameter regression model based on fractional polynomial was used to establish the reference values of CIMT by age and sex. Results: A total of 2 163 healthy individuals were enrolled in the final analysis, including 576 males (26.6%) and 1 587 females (73.4%). The fractional polynomial regression of the CIMT mean and standard deviation was obtained. For men, the regression was meanCIMT=0.324 7+0.006 9×age and SDCIMT=0.076 9+0.001 2×age. For women, the regression was meanCIMT=0.354 9+0.005 4×age and SDCIMT=0.041 6+0.002 0×age. Conclusion: The age and sex reference values for CIMT of adult people in Shenzhen established in this study could provide the latest reference standards for early screening of subclinical CVD.

Abstract
Objective: To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE)-hepatic arterial infusion chemotherapy (HAIC)-targeted-immune quadruple therapy in patients with intermediate and advanced-stage hepatocellular carcinoma (HCC). Methods: 101 patients with intermediate and advanced stage HCC were enrolled according to the inclusion and exclusion criteria, and then they were divided into a combination group and a control group. Patients in the combination group was treated with TACE-HAIC-targeted-immune quadruple therapy, while the control group was only treated with TACE therapy. The overall survival (OS), progression-free survival (PFS), and treatment-related adverse reactions were statistically analyzed in the two groups of patients. Statistical analysis was carried out by t-test, χ2 test, rank sum test, Kaplan-Meier curve, log-rank test, Cox regression (or proportional hazards model) analysis according to different data. Results: The tumor objective response rate and disease control rate as evaluated by mRECIST 1.1 criteria in the combination group were 80% and 94%, respectively, which were significantly higher than those in the control group, 41.2% (P<0.001) and 74.5% (P=0.007). The OS and PFS of the combination group were 15.6 months [95%CI 11.3-NA ] and 8.8 months [95%CI 6.9-12.0], respectively, which were significantly better than the control group at 6.1 months [95%CI 5.3-6.6] (P<0.001) and 3.2 months [95%CI 3.0-3.6] (P<0.001). Gastric ulcer incidence was significantly higher in the combination group (9/50, 18%) than that in the control group (2/51, 3.9%) (P=0.023). Conclusion TACE-HAIC-targeted-immune quadruple therapy is a more effective treatment mode for intermediate and advanced-stage HCC than TACE alone, and attention should be paid to the monitoring of target immune-related adverse reactions.

Abstract
Objective:To investigate the expression of RhoA, Ezrin and CD44 proteins in laryngeal squamous cell carcinoma (LSCC), and analyze their roles and mutual relations in invasion and metastasis.Method:The expressions of RhoA, Ezrin and CD44 in 68 specimens of LSCC and 35 specimens of normal laryngeal mucosa tissues were detected by immunohistochemical SABC staining. The results were correlated with clinicopathological parameters.Result:The positive expression rates of RhoA, Ezrin and CD44 in LSCC were 80.9%,82,4% and 70.6%, and the positive expression rates of RhoA, Ezrin and CD44 in normal laryngeal mucosa tissues were 28.5%, 25.7% and 20%, respectively. The expressions of RhoA, Ezrin and CD44 were significantly correlated to depth of invasion (T), lymph node metastasis (N), clinical TNM stage, tumor grade respectively (P< 0.05), but not to age, gender, smoking, tumor location (P> 0.05). The expression of RhoA was positively correlated to that of Ezrin in LSCC, and the expression of Ezrin was positively correlated to that of CD44 in LSCC too (P< 0.05).Conclusion:Our findings suggested that high expressions of RhoA, Ezrin and CD44 might play an important role in the malignant progression of invasion and metastasis of LSCC, which indicated that they might have played synergistic effects in the process.

Abstract
Objective: o investigate the features of pathogenic bacteria for community-acquired bloodstream infection due to Gram-negative bacilli in patients with liver cirrhosis and optimal therapeutic strategy. Methods: A retrospective analysis was performed for the clinical data of patients with liver cirrhosis who were admitted to 302 Hospital of PLA due to community-acquired bloodstream infection from January 2010 to December 2015, and a statistical analysis was performed for their clinical features, pathogenic bacteria, and results of drug sensitivity test. The Pearson chi-square test was used for comparison of rates, and the Wilcoxon rank sum test was used for comparison of ranked data. Results: A total of 240 patients (including 178 male patients) with liver cirrhosis caused by various reasons were enrolled, with a mean age of 51.7 ± 11.1 years, an overall clinical remission rate of 80.42%, and an ineffective/mortality rate of 19.58%. The patients who used sensitive antibiotics within 12 hours after the onset of community-acquired bloodstream infection achieved a significantly higher improvement rate than those who used such drugs at more than 12 hours after onset (88.2% vs 58.1%, P < 0.001). The improvement rate achieved by the application of sensitive antibiotics at more than 12 hours after onset decreased with the increase in the Child-Pugh grade (P < 0.05). A total of 245 strains of Gram-negative bacilli were isolated, among which the six most common ones were 135 strains of Escherichia coli (55.1%), 62 strains of Klebsiella pneumoniae (25.3%), 16 strains of Aeromonas (6.5%), 4 strains of non-typhoidal Salmonella (1.6%), 3 strains of Enterobacter cloacae (1.2%), and 2 strains of Acinetobacter baumannii (0.8%). These Gram-negative bacilli had the highest sensitivity to meropenem (98.5%), followed by imipenem (97.9%), amikacin (97.5%), piperacillin/tazobactam (94.7%), cefmetazole (93.7%), and cefoperazone/sulbactam (93%). Different bacteria had different sensitivities to antibiotics. Conclusion: Once community-acquired bloodstream infection occurs in patients with liver cirrhosis, highly sensitive antibiotics should be used as early as possible. Cefoperazone/sulbactam, piperacillin/tazobactam, imipenem, and meropenem can be used as first-line empirical antibiotics, and drug combination should be considered when necessary.

Abstract
This study aimed to disclose the potential causality of low bilirubin in patients with nephrotic syndrome (NS). Correlation analysis was carried out on total bilirubin (TBIL) to serum albumin (ALB), urine protein (Upr), and urinary microalbumin/creatinine (Umalb/cr) for three groups in a case-control study. P < 0.001 was observed for TBIL, ALB, Umalb/cr, and Upr between the NS and chronic nephritis (CN) groups, and P values of 0.0001, 1.000, 0.0001, and 0.0001 were observed for TBIL, ALB, Umalb/cr, and Upr, respectively, between the postoperative gastroparesis (PGS) and CN groups. The values of r and P in correlation to TBIL were 0.549 and 0.000 for ALB, -0.405 and 0.000 for Umalb/cr, and -0.448 and 0.000 for Upr in the NS group; -0.007 and 0.959 for ALB, 0.213 and 0.091 for Umalb/cr, and -0.082 and 0.519 for Upr in the PGS group; and 0.509 and 0.000 for ALB, -0.431 and 0.000 for Umalb/cr, and -0.362 and 0.002 for Upr in the CN group. A probable causality is implied between the low level of blood bilirubin and its loss in urine in NS patients. This conclusion may provide a theoretical basis for the feasibility of therapies against oxidative stress in NS patients.

Abstract
To establish a proteomic reference map of Musa acuminate Colla (banana) leaf, we separated and identified leaf proteins using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry (MS). Tryptic digests of 44 spots were subjected to peptide mass fingerprinting (PMF) by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) MS. Three spots that were not identified by MALDI-TOF MS analysis were identified by searching against the NCBInr, SwissProt, and expressed sequence tag (EST) databases. We identified 41 unique proteins. The majority of the identified leaf proteins were found to be involved in energy metabolism. The results indicate that 2D-PAGE is a sensitive and powerful technique for the separation and identification of Musa leaf proteins. A summary of the identified proteins and their putative functions is discussed.

Abstract
The problem of localized bulging in inflated membrane tubes shares the same features with a variety of other localization problems such as formation of kink bands in fibre-reinforced composites and layered structures. This type of localization is known to be very sensitive to imperfections, but the precise nature of such sensitivity has not so far been quantified. In this paper, we study effects of localized wall thinning/thickening on the onset of localized bulging in inflated membrane tubes as a prototypical example. It is shown that localized wall thinning may reduce the critical pressure or circumferential stretch by an amount of the order of the square root of maximum wall thickness reduction. As a typical example, a 10 per cent maximum wall thinning may reduce the critical circumferential stretch by 19 per cent. This square root law complements the well-known Koiter's two-thirds power law for subcritical periodic bifurcations. The relevance of our results to mathematical modelling of aneurysm formation in human arteries is also discussed.

Abstract
Commercial banana varieties are highly susceptible to fungal pathogens, as well as bacterial pathogens, nematodes, viruses, and insect pests. The largest known family of plant resistance genes encodes proteins with nucleotide-binding site (NBS) and C-terminal leucine-rich repeat (LRR) domains. Conserved motifs in such genes in diverse plant species offer a means for the isolation of candidate genes in banana that may be involved in plant defense. Six degenerate PCR primers were designed to target NBS and additional domains were tested on commercial banana species Musa acuminata subsp malaccensis and the Musa AAB Group propagated in vitro and plants maintained in a greenhouse. Total DNA was isolated by a modified CTAB extraction technique. Four resistance gene analogs were amplified and deposited in GenBank and assigned numbers HQ199833-HQ199836. The predicted amino acid sequences compared to the amino acid sequences of known resistance genes (MRGL1, MRGL2, MRGL3, and MRGL4) revealed significant sequence similarity. The presence of consensus domains, namely kinase-1a, kinase-2 and hydrophobic domain, provided evidence that the cloned sequences belong to the typical non-Toll/interleukin-1 receptor-like domain NBS-LRR gene family.

Abstract
Restriction maps of rDNA repeats of five species of Colobinae and three outgroup taxa, Hylobates leucogenys, Macaca mulatta, and Macaca irus, were constructed using 15 restriction endonucleases and cloned 18S and 28S rRNA gene probes. The site variation between Rhinopithecus roxellana and Rhinopithecus bieti is comparable to that between Presbytis françoisi and Preshytis phayrei, implying that R. bieti is a valid species rather than a subspecies of R. roxellana. Phylogenetic analysis on the 47 informative sites supports the case for Rhinopithecus being an independent genus and closely related to Presbytis. Furthermore, branch lengths of the tree seem to support the hypothesis that the leaf monkeys share some ancestral traits as well as some automorphic characters.

Abstract
We constructed a plasmid that contains a small piece of DNA with two vaccinia promoters running in opposite directions--a promoter from a late gene encoding an 11 K polypeptide (P11) and a promoter from an early gene encoding 25K (P25). These promoters were isolated from the Tian Tan strain of vaccinia virus and were flanked by the thymidine kinase (TK) sequence of the same virus. Genes encoding the hepatitis B virus surface antigen (HBsAg) and the Escherichia coli beta-galactosidase (LacZ) were inserted downstream of the 11 K and 25 K promoters respectively so that coexpression plasmids were constructed. Recombinant vaccinia viruses were selected directly by picking blue plaques formed under overlaying agarose medium containing X-gal. HBsAg was expressed to high level by these recombinant viruses. These recombinant viruses showed reduced virulence on rabbit skin and induced anti-HBs after intradermal inoculation of rabbits.

Abstract
Brief periods of cerebral ischemia result in prolonged inhibition of protein synthesis. In CA1 sector of hippocampus inhibition is irreversible, leading to delayed death of pyramidal neurons. In order to study the possible role of gene transcription in this process, expression of four individual RNAs was investigated in the gerbil brain after 5 min of global cerebral ischemia by in situ hybridization with the following nucleic acid probes: plasmid pMr100 (ribosomal RNA sequences), plasma pAG82 (cytochrome c oxidase sequences), plasmid p629 (amyloid A4 precursor protein of Alzheimer's disease, pre-A4 protein), and plasmid pHF beta A-1 (beta-actin sequences). Cytochrome c oxidase mRNA and ribosomal RNA did not show any changes in expression up to 48 hr after ischemia. After longer recirculation times they gradually declined in the CA1 sector of hippocampus in parallel with the morphological manifestation of delayed neuronal death. The pre-A4 mRNA transiently decreased after 8 hr of recirculation of the CA1 sector but then recovered before it finally disappeared in parallel with delayed neuronal death. The beta-actin mRNA transiently appeared to increase after 8 hr of recirculation in the stratum radiatum of hippocampus but then also declined and disappeared when CA1 neurons began to disintegrate. The possible significance of these changes in the pathogenesis of ischemic neuronal damage is discussed.
