Abstract
OBJECTIVE Gestational diabetes mellitus (GDM) is a serious pregnancy complication, and women with undiagnosed diabetes mellitus can develop chronic hyperglycemia during pregnancy. The purpose of this study is to investigate the impact of information-based continuity of care on glucose levels, health awareness, and maternal and infant outcomes in pregnant women with GDM, thereby providing a basis for the clinical implementation of effective interventions for GDM to reduce or avoid adverse outcomes due to GDM. PATIENTS AND METHODS One hundred and sixty cases of pregnant women with GDM who underwent treatment in the obstetrics and gynecology department of our hospital from June 2019 to September 2021 were randomly selected as the study population and divided into the control group (n=80) and the study group (n=80). Women in the control group were received with conventional nursing intervention, and those in the study group were obtained with information-based continuity of care on the basis of the control group. Basic clinical data were collected. The levels of fasting blood glucose (FBG), 2h postprandial glucose (2hPG), knowledge of health education, treatment compliance scores, and changes in delivery outcomes were compared between the two groups. According to the maternal blood glucose control level, 160 pregnant women with GDM were divided into the better control group (143 cases) and the poor control group (17 cases). The risk factors affecting the level of maternal glycemic control in gestational diabetes were analyzed. RESULTS After the intervention, the levels of FBG and 2hPG were significantly lower in both groups than those before the intervention, while the levels of FBG and 2hPG in the study group were notably lower than those in the control group. The health education knowledge score and treatment compliance score after the intervention were significantly higher than those before the intervention, and the health education knowledge score and treatment compliance score in the study group were observably higher than those in the control group (p<0.01). The adverse pregnancy outcomes of pregnant women in the study group were significantly reduced compared with those in the control group (p<0.05). Logistic regression analysis showed that body mass index (BMI), dietary control, literacy, and information-based continuity of care were all influential factors for maternal glycemic control level (p<0.05). Among the influencing factors, dietary control and continuity of care had clinical value in predicting maternal glycemic control levels in gestational diabetes. CONCLUSIONS Continuous nursing based on informatization can effectively control the blood glucose level of pregnant women with GDM, improve the treatment compliance of pregnant women and the awareness rate of gestational diabetes knowledge so as to reduce the occurrence of adverse pregnancy outcomes and improve the health level. In addition, BMI and dietary control are independent risk factors that affect the blood glucose control level of pregnant women. Relevant intervention measures should be formulated according to the relevant influencing factors to effectively control the blood glucose level of pregnant women with GDM and improve maternal and infant outcomes.

Abstract
The two most commonly used airway management techniques during general anaesthesia are supraglottic airway devices and tracheal tubes. In older patients undergoing elective non-cardiothoracic surgery under general anaesthesia with positive pressure ventilation, we hypothesised that a composite measure of in-hospital postoperative pulmonary complications would be less frequent when a supraglottic airway device was used compared with a tracheal tube. We studied patients aged ≥ 70 years in 17 clinical centres. Patients were allocated randomly to airway management with a supraglottic airway device or a tracheal tube. Between August 2016 and April 2020, 2900 patients were studied, of whom 2751 were included in the primary analysis (1387 with supraglottic airway device and 1364 with a tracheal tube). Pre-operatively, 2431 (88.4%) patients were estimated to have a postoperative pulmonary complication risk index of 1-2. Postoperative pulmonary complications, mostly coughing, occurred in 270 of 1387 patients (19.5%) allocated to a supraglottic airway device and 342 of 1364 patients (25.1%) assigned to a tracheal tube (absolute difference -5.6% (95%CI -8.7 to -2.5), risk ratio 0.78 (95%CI 0.67-0.89); p < 0.001). Among otherwise healthy older patients undergoing elective surgery under general anaesthesia with intra-operative positive pressure ventilation of their lungs, there were fewer postoperative pulmonary complications when the airway was managed with a supraglottic airway device compared with a tracheal tube.

Abstract
Acute-on-chronic liver failure (ACLF) is a potentially reversible entity that occurs in patients with chronic liver disease accompanied with or without cirrhosis and is characterized by extrahepatic organ failure and high short-term mortality. Currently, the most effective treatment method for patients with ACLF is liver transplantation; therefore, admission timing and contraindications must be emphasized. The function of vital organs such as the heart, brain, lungs, and kidneys should be actively supported and protected during the liver transplantation perioperative period in patients with ACLF. Focusing on the anesthesia management level during anesthesia selection, intraoperative monitoring, three-stage management, prevention and treatment of post-perfusion syndrome, monitoring and management of coagulation function, volume monitoring and management, and body temperature monitoring management for liver transplantation should strengthen anesthesia management. Additionally, standard postoperative intensive care treatment should be recommended, and grafts and other vital organ functions should be monitored throughout the perioperative period to promote early postoperative recovery in patients with ACLF.

Abstract
Objective: To compare the value of the modified European Society of Urogenital Radiology (ESUR) score and Mehralivand grade based on biparametric MRI (bpMRI) in the assessment of extracapsular extension (ECE) in patients with prostate cancer (PCa). Methods: Data of 235 patients with postoperative pathology confirmed PCa, who underwent preoperative 3.0 T bpMRI examinations between March 2019 and March 2022 in the First Affiliated Hospital of Soochow University were retrospectively evaluated, including 107 ECE positive and 128 ECE negative cases, aged [M (Q1, Q3)] [71 (66, 75)] years. Reader 1 and 2 assessed the ECE using the modified ESUR score and Mehralivand grade, and the receiver operating characteristic curve and Delong test were used to evaluate the performance of the two scoring methods. Then, the statistically significant variables were included in multivariate binary logistics regression analysis to obtain the risk factors, which were combined with the scores of reader 1 to establish combined models. The assessment ability of the two combined models and the two scoring methods were compared subsequently. Results: The AUC of Mehralivand grade in reader 1 were higher than that of the modified ESUR score in reader 1 and 2 [0.746 (95%CI: 0.685-0.800) vs 0.696 (95%CI: 0.633-0.754) and 0.691 (95%CI: 0.627-0.749), both P<0.05]. The AUC of Mehralivand grade in reader 2 was higher than that of the modified ESUR score in reader 1 and 2 [0.753 (95%CI: 0.693-0.807) vs 0.696 (95%CI: 0.633-0.754) and 0.691 (95%CI: 0.627-0.749), both P<0.05]. The AUC of the combined model 1 based on the modified ESUR score and the combined model 2 based on Mehralivand grade were higher than that in the separate modified ESUR score [0.826 (95%CI: 0.773-0.879) and 0.841 (95%CI: 0.790-0.892) vs 0.696 (95%CI: 0.633-0.754), both P<0.001], and also higher than that in the separate Mehralivand grade [0.826 (95%CI: 0.773-0.879) and 0.841 (95%CI: 0.790-0.892) vs 0.746 (95%CI: 0.685-0.800), both P<0.05]. Conclusion: Based on bpMRI, the Mehralivand grade showed better diagnostic performance for assessing ECE preoperatively in patients with PCa than the modified ESUR score. The combination model of scoring methods and clinical variables can further enhance the diagnostic certainty in the assessment of ECE.

Abstract
Objective: To explore accurate prenatal diagnosis, full-coverage graded counseling and follow-up for the fetus with cardiac birth defects (CBD). Methods: CBD fetus diagnosed prenatal by echocardiography from January 2018 to December 2020 in Guangdong Provincial People's Hospital were enrolled. Fetal CBD was graded (Ⅰ-Ⅵ) according to prognosis and possible operation time after birth, and the classification criteria and common diseases included were proposed. After the prenatal grading counseling, the outcome of the fetus was followed-up. The induced labor rate, live birth rate, prenatal and postnatal ultrasound diagnosis coincidence rate and other indicators were calculated. The disease composition ratio, prognosis of fetus with different grades and the outcome of integrated treatment were analyzed. Results: The detection rate of fetal CBD was up to 16.2% (1 971/12 188), 30 cases of which were excluded. A total of 1 941 cases were included in this study, including 196 cases (10.1%) of gradeⅠ, 433 cases (22.3%) of gradeⅡ, 615 cases (31.7%) of grade Ⅲ, 261 cases (13.4%) of grade Ⅳ, 388 cases (20.0%) of gradeⅤ, 48 cases (2.5%) of grade Ⅵ. Grade Ⅱ and gradeⅢ (the operation time was within 1 year after birth) accounted for 54.0% (1 048/1 941). The distribution of some diseases in different grades had obvious proportion advantage, which was representative. Among 1 747 CBD fetus, 736 cases (induced labor rate 42.1%) chose to terminate pregnancy due to CBD. Of the 1 010 live births, 975 cases (96.5%) had the same prenatal and postnatal diagnosis, 3 cases were missed diagnosis and 32 cases were misdiagnosed. The diagnostic accuracy of live births with severe and complex congenital heart disease was 383 out of 389 (98.5%). A total of 258 cases have received surgery or intervention. The age at the time of surgery or intervention was different among grades(χ²=47.3,P<0.001). With the improvement of prognosis from gradeⅠ to Ⅴ, the live birth rate increased and the induced labor rate decreased accordingly; the difference between grades was significant(χ²=623.6,P<0.001). Conclusions: Prenatal diagnosis and graded counseling is important in the integrated model. Fetal CBD grading could refine post-natal treatment strategies, guide delivery decisions and become an evaluation standard.

Abstract
Objective: To develop and validate a useful predictive model for large gestational age (LGA) in pregnancy using a machine learning (ML) algorithm and compare its performance with the traditional logistic regression model. Methods: Data were obtained from the National Free Preconception Health Examination Project in China, carried out in 220 counties of 31 provinces from 2010 to 2012, covering all rural couples with a planned pregnancy. This study included all teams of childbearing age who delivered newborns within 24-42 weeks of gestational age and their newborns. Ten different ML algorithms were used to establish LGA prediction models, and the prediction performance of these models was evaluated. Results: A total of 104 936 newborns were included, including 54 856 boys (52.3%) and 50 080 girls (47.7%). The incidence of LGA was 11.7% (12 279). The imbalance between the two groups was addressed by the under- sampling technique, after which the overall performance of the ML models was significantly improved. The CatBoost model achieved the highest area under the receiver-operating-characteristic curve (AUC) value of 0.932. The logistic regression model had the worst performance, with an AUC of 0.555. Conclusions: In predicting the risk for LGA in pregnancy, the ML algorithms outperform the traditional logistic regression method. Compared to other ML algorithms, CatBoost could improve the performance, and it deserves further investigation.

Abstract
Objective: To observe the adverse reactions of Diphtheria, Tetanus, Acellular Pertussis and Haemophilus Influenzae Type b Combined Vaccine conjugate vaccine at the anterolateral thigh muscle, upper arm deltoid muscle and upper gluteal region. Methods: A total of 12 241 infants who were voluntarily vaccinated DTaP-Hib from April 2015 to April 2019 in Beijing were selected for the study. DTaP-Hib vaccine is recommended for 3, 4, 5 months of age for basic immunization and 18 to 24 months of age to strengthen immunization. Subjects were divided into the groups of lateral thigh muscle, the upper arm deltoid and upper gluteal region according to the actual inoculation sites. Adverse reactions were collected within 30 minutes and 7 days after each does of vaccination at different sites and compared between three groups. The incidence of adverse reactions at the three different inoculation sites was compared by Chi-square test. Results: A total of 12 241 infants and toddlers received combined DTaP-Hib and 35 027 doses of DTaP-Hib were investigated. The number and of lateral thigh muscles, upper arm deltoids and gluteal muscles were 3 461 infants and 11 129 doses, 2 659 infants and 7 957 doses, 6 121 infants and 15 941 doses respectively. A total of 2 489 adverse reactions occurred. The incidence of adverse reactions was 7.11%. The incidence of adverse reactions in deltoid muscle of upper arm was 9.69%(771 doses), which was higher than that in gluteal muscle (7.58%, 1 211 doses) and anterolateral muscle of thigh (4.56%, 507 doses). The incidence of mild, moderate and severe adverse reactions in the upper arm deltoid group were higher than those in the other two groups. The incidence rates were 4.85% (386 doses), 3.77% (300 doses) and 1.07% (85 doses) respectively. The differences between groups were statistically significant(P<0.001). The total adverse reactions of the three doses of basic immunization and the fourth dose of enhanced immunization had the same trend in different parts. The incidence of adverse reactions was in the order of the upper arm deltoid injection, upper gluteal injection and lateral thigh muscle injection from high to low. The differences were statistically significant (P<0.001). Conclusion: The incidence of adverse reactions of DTaP-Hib vaccination in three different sites was low, which confirmed that the DTaP-Hib vaccination got expected safety regardless of the sites of inoculation. The lateral femoral muscle group had the lowest incidence of adverse reactions, hence it should be preferred as the inoculation site of DTaP-Hib vaccination.

Abstract
Immunocastration (vaccination against Gonadotropin-releasing hormone (GnRH)) has been regarded as a friendly substitution to physical castration in animals. To date, a few studies have reported the use of Improvac for immunocastration in boar and one study in broiler chickens; however, there is an apparent dearth of scientific evidence regarding the application of Improvac for immunocastration in birds. In the present study, we evaluated the effects of Improvac-based immunocastration on testosterone levels and spermatogenesis in broiler chickens and the effects of Improvac on the expression of genes related to testosterone biosynthesis and metabolism as well as spermatogenesis. The birds were randomly divided into 4 groups (n = 30 each): Control group (non-immunized), Early group (immunized with Improvac at week 3), Late group (immunized with Improvac at week 6), and Early + Late group (immunized with Improvac at weeks 3 and 6). Immunization with Improvac significantly improved the average daily gain compared to the Control group. Of note, following Improvac vaccination, the reproductive efficiency was significantly decreased in male broiler chickens. Furthermore, parameters such as the serum testosterone concentration, spermatogenesis, and the expression levels of genes related to testosterone metabolism (Cyp17A1, Cyp19, HSD3B1, and HSD17B3) and spermatogenesis (Cyclin A1 and Cyclin A2) were significantly reduced in the immunized groups compared to the Control group. Taken together, these findings reveal that immunization against GnRH can be achieved, at least partially, in male broiler chickens. The results of our study also support the hypothesis of using Improvac as an alternative solution to caponization, with considerably improved animal welfare.

Abstract
OBJECTIVE To investigate the expressions and effects of G250, B-cell lymphoma-2 associated X protein (Bax) and Bcl-2 in rats with renal clear cell carcinoma (RCCC). MATERIALS AND METHODS A total of 66 male Sprague-Dawley (SD) rats were selected, among which 56 were selected to establish RCCC rat model and the remaining 10 were selected as control group. Three weeks after modeling, 4 rats failed in the modeling. Expressions of G250 in RCCC rat model group and healthy rat model control group were detected by Reverse Transcription-Polymerase Chain Reaction (RT-PCR); expressions of Bcl-2 and Bax in each group were detected by Western blot and their effects were analyzed. RESULTS The positive expression rates of G250 in 52 RCCC rats in model group and 10 healthy rats in control group were 83.3% and 0%, respectively. The results showed that expression of G250 had a certain correlation with the pathological changes of RCCC (p < 0.01). Expressions of Bax and Bcl-2 were up-regulated in the RCCC group, while expressions were down-regulated in the healthy control group (p < 0.05). CONCLUSIONS G250, as a new specific marker of renal cell carcinoma, is involved in the pathological changes of renal cell carcinoma. Joint detection of Bax and Bcl-2 can be used as an important index for the diagnosis of RCCC.

Abstract
Objective: To explore the association between gestational weight gain (GWG) and adverse pregnancy outcomes. Methods: A prospective study was conducted among 1 220 healthy singleton pregnant women in the first trimester of pregnancy, from Chengdu city, Sichuan province. Pre-gestational body mass and other basic information were collected through a set of questionnaires. Weight at the last week before delivery was measured and GWG was classified by IOM criteria (2009). Related information on pregnancy outcomes was collected after delivery, through the hospital information system. Multiple non-conditional logistic regression models were used to test the association between GWG and adverse pregnancy outcomes. Results: In total, data on 1 045 pregnant women were analyzed. Compared with adequate GWG, excessive GWG was associated with the increased risks of cord entanglement and large for gestational age (OR=1.641, 95%CI: 1.197-2.252; OR=1.678, 95%CI: 0.132-2.488), respectively. Additionally, when compared with the adequate GWG, insufficient GWG was associated with the increased risk of preterm delivery (OR=3.189, 95%CI: 1.604-6.341). Conclusions: Both excessive and insufficient GWG appeared associated with the pregnancy outcomes. Weight monitoring should be strengthened for pregnant women to reduce related risks on adverse pregnancy outcomes.

Abstract
Objective: To study the relations between famine exposure and the risk of chronic diseases as diabetes mellitus, obesity, hypertension, coronary heart disease and stroke in the population of Harbin. Methods: Our data was collected from the baseline survey-the China Kadoorie Biobank project (CKB) in Harbin. Retrospective cohort study design was used. Related risks on chronic diseases including diabetes mellitus, obesity, hypertension, coronary heart disease and stroke, were compared among the famine exposed or non-exposed people, respectively by logistic analysis method. Results: After adjusted for factors as age, sex, physical activity, smoking, alcohol intake, diet, family history of diseases, it appeared that the factor 'famine exposure' had increased the risks of diseases as obesity (OR=1.204, 95%CI: 1.104-1.313, P<0.01), hypertension (OR=1.315, 95%CI: 1.210-1.429, P<0.01) and coronary heart disease (OR=1.495, 95%CI: 1.369-1.632, P<0.01). The lower the age of population being exposed to famine, the greater the risk of the development of all kinds of chronic diseases. Conclusions: Famine exposure appeared a risk factor for obesity, hypertension, and coronary heart disease. It is of great significance to ensure the life-long nutrition of the people, especially in the early and adolescent stages, to prevent obesity, hypertension, and coronary heart disease in their later lives.

Abstract
Objective: To investigate the comprehensive nutritional status and diet behavior of middle aged and elderly women with osteoporosis, and thereby to explore the relationship between diet behavior and comprehensive nutritional status. Methods: 311 middle-aged and elderly women with osteoporosis in Chengdu were included in this study. Mini Nutritional Assessment (MNA) was applied to assess their comprehensive nutritional status. Information of social-demographic characteristics and diet behavior (about meals, snacks and water drinking, etc.) of the subjects was collected by questionnaire. Chi square test was used to assess the differences in nutritional status among patients who have different eating behaviors. Logistic regression analysis was performed to evaluate the relationship between diet behaviors and comprehensive nutritional status. Results: The mean MNA score of subjects was 25.8±2.5. 20.3% (63/311) of the subjets were at risk of potential malnutrition, but there was no malnourished subjects found. 46.9% (46/311) of the subjects were in good appetite. 95.2% (296/311) of them had a fixed food intake each meal. 65.8% (198/311) of them had snacks every day, and the most common choice was fruit (86.4% (248/287)). 54.8% (165/311) of them had initiative drinking water habits, and the most common choice was plain boiled water (79.9%, 246/308). 76.5% (238/311) of them had daily portable water less than 1 500 ml. After adjusting the effects of age, occupation and education level, bad appetite (OR=3.50, 95%CI: 1.18-10.62), unfixed food intake (OR=7.27, 95%CI: 1.40-35.83), and seldom or never intake of snack (OR=3.71, 95%CI: 1.42-9.72) were risk factors for malnutrition risk, while tea drinking was protective factor(OR=0.31, 95%CI: 0.11-0.93). Conclusion: Risk of potential malnutrition and unhealthy diet behavior among the middle aged and elderly women with osteoporosis should be paid more attention. Unhealtghy diet behavior has a negative effect on their comprehensive nutritional status.

Abstract
OBJECTIVE The aim of the present study was to clarify the expression pattern and prognostic role of RABEX-5 mRNA in colorectal cancer (CRC) patients. PATIENTS AND METHODS RABEX-5 mRNA levels in 187 CRC were examined by Real-time polymerase chain reaction. Then, the association of RABEX-5 mRNA levels with clinicopathological features was analyzed. Survival curves were plotted using the Kaplan-Meier method and differences in survival rates were analyzed using the log-rank test. The influence of each variable on survival was examined by the Cox multivariate regression analysis. RESULTS RABEX-5 mRNA expression was significantly upregulated in CRC tissues compared with the adjacent noncancerous tissues (p < 0.01). By statistical analyses, high RABEX-5 mRNA expression was observed to be closely correlated with histology/differentiation (p = 0.010), N classification (p = 0.004), and TNM stage (p = 0.004). Kaplan-Meier curves showed that patients with high RABEX-5 mRNA expression showed unfavorable overall survival (OS) than the low RABEX-5 mRNA expression group (p < 0.001). Finally, univariate and multivariate analyses showed that RABEX-5 mRNA expression was an independent predictor of overall survival (p < 0.05). CONCLUSIONS RABEX-5 mRNA may be a promising biomarker for the detection and prognosis evaluation of CRC.

Abstract
The prevention of chemotherapy‐induced nausea and vomiting was one of the most challenging supportive care issues in oncology, especially to highly emetogenic chemotherapy (HEC). A total of 645 patients were randomized into fosaprepitant group (fosaprepitant/placebo 150 mg d1 in combination with granisetron and dexamethasone) or aprepitant group (aprepitant/placebo 125 mg d1; 80 mg d2‐d3 plus granisetron and dexamethasone).The primary endpoint was the percentage of patients who had a complete response (CR) over the entire treatment course (0–120 hr, overall phase [OP]). It was assessed by using a non‐inferiority model, with a non‐inferiority margin of 10%. The difference of the CR rate was compared between two groups with chi‐square analysis. Six hundred and twenty‐six patients were included in the per protocol analysis. The percentage of patients with a CR in the fosaprepitant group was not inferior to that in the aprepitant group (90.85% versus 94.17%, p = .1302) during OP. Whether the cisplatin‐based chemotherapy or not, the CR rate of the fosaprepitant group was not inferior to that of the aprepitant group. Both regimens were well tolerated. The most common adverse event was constipation. Fosaprepitant provided effective and well‐tolerated control of nausea and vomiting associated with HEC in Chinese patients.

Abstract
Objective: To detect the alterations of telomerase activity and the expression for oxidative stress responsive genes related with senescence during cellular replicative senescence and hydrogen peroxide-induced premature senescence in human embryonic lung fibroblasts (HELFs) in vitro. Methods: The HELFs were divided into young cells (22 population doubling levels, 22PDL) , mid-aged cells (35PDL) and replicative senes-cent cells (49PDL) and premature senescent cells induced by H(2)O(2)(premature senescence, PS). The telomerase activity was detected by ELISA assay during cellular replicative and premature senescence. The mRNA level of oxidative stress responsive genes related with senescence for Foxo1, Foxo3, Pdx1, apoA-I and MMP1 was per-formed by RT-Q-PCR separately. Results: The mRNA level for Foxo1, Foxo3, apoA-I and Pdx1 was decreased separately during cellular replicative senescence compared to that in the young-stage cells with statistical signifi-cance (P<0.05). The expression of MMP1 was up-regulated 5.1-fold obviously (P<0.05). In premature senes-cence, the mRNA level was only decreased for Foxo1, Foxo3 and apoA-I, but up-regulated 2.3-fold and 6.2-fold for Pdx1 and MMP1 respcetively vs 22PDL significantly (P<0.05). The telomerase activity in young cells was not detected, and it increased in mid-aged cells and replicative senescence stages during cellular replicative se-nescence as compared to 22PDL with statistical significance (P<0.05). The telomerase activity in premature se-nescence was highly active. Conclusion: The expression for genes related with senescence has differences be-tween replicative and premature senescence and hydrogen peroxide modifies their expression levels. The telomer-ase activity has been going up with increased PDLs.

Abstract
Random amplified polymorphic DNA (RAPD) is a widely used molecular marker technique. As traditional RAPD has poor reproducibility and productivity, we previously developed an improved RAPD method (termed RAMP-PCR), which increased the reproducibility, number of bands, and efficiency of studies on polymorphism. To further develop the efficiency of this method, we used high-GC content primers for improved RAMP-PCR with DNA samples from Lonicera japonica. Comparison of amplification profiles obtained by standard RAPD primers with those obtained by regular PCR and RAMP-PCR, and high-GC primers with regular PCR and RAMP-PCR showed that the average number of bands and polymorphisms per primer gradually and significantly increased (from 6.4 to 15.0 and from 4.6 to 10.2, respectively). Cluster dendrograms showed similar results, indicating that this new method is consistent and reproducible. A total of 22 samples from different species, including plants, animals, and humans, were used for RAMP-PCR with high-GC primers. Multiple bands were successfully amplified from all samples, demonstrating that this method is a reliable technique with consistent results and may be of general interest in studies on different genera and species. We developed highly effective DNA markers, which can provide a more effective and potentially valuable approach than traditional RAPD for the genetic identification of various organisms, particularly of medicinal plants.

Abstract
Our study aimed to investigate the role of 2 ERCC5 promoter SNPs (rs2094258 and rs751402) in the development of gastric cancer in the Chinese population. The present hospital-based case-control study consisted of 155 patients with gastric cancer and 246 healthy controls recruited between March 2012 and December 2014. Genotyping for the rs2094258 and rs751402 polymorphic sites was carried out using polymerase chain reaction-restriction fragment length polymorphism. Statistical analyses were conducted using the SPASS version 16.0 software (SPSS, Inc., Chicago, IL, USA). As determined by the chi-square test, there was a significant difference in the genotype distributions of rs751402 between patients and controls (X2 = 6.74, P = 0.03). By unconditional logistic regression analysis, we observed that the TT genotype in rs751402 was significantly associated with increased risk to gastric cancer as compared with the CC genotype, and the adjusted OR (95%CI) was 2.17 (1.15-4.09). Moreover, subjects carrying the T allele in rs751402 had elevated risk of developing gastric cancer when compared with those carrying the C allele, with an adjusted OR value (95%CI) of 1.47 (1.09-1.99). In conclusion, we suggest that the ERCC5 rs751402 gene polymorphism may influence the susceptibility to gastric cancer in the Chinese population.

Abstract
Sequence-characterized amplified region (SCAR) markers were further developed from high-GC primer RAMP-PCR-amplified fragments from Lonicera japonica DNA by molecular cloning. The four DNA fragments from three high-GC primers (FY-27, FY-28, and FY-29) were successfully cloned into a pGM-T vector. The positive clones were sequenced; their names, sizes, and GenBank numbers were JYHGC1-1, 345 bp, KJ620024; YJHGC2-1, 388 bp, KJ620025; JYHGC7-2, 1036 bp, KJ620026; and JYHGC6-2, 715 bp, KJ620027, respectively. Four novel SCAR markers were developed by designing specific primers, optimizing conditions, and PCR validation. The developed SCAR markers were used for the genetic authentication of L. japonica from its substitutes. This technique provides another means of developing DNA markers for the characterization and authentication of various organisms including medicinal plants and their substitutes.

Abstract
The aim of this study was to investigate the effect of phosphatidylserine (PS) on memory of patients and rats with Alzheimer's disease (AD). In total, 57 AD patients were recruited from our hospital, and were divided into two groups: 25 in the control group and 32 in the observation group. Next, 300 mg/d of PS was given to the rats in the observation group for 12 continuous weeks based on the control group. AD rats were divided into three groups: control group, PS 30 mg/kg group, and PS 15 mg/kg group. Learning memory ability and free radical levels in the brain were detected after treatment. In AD patients, vocabulary and picture matching scores in the two treatment groups increased after treatment (P < 0.05). Moreover, the scores in the treated group were significantly greater than the control group (P < 0.05). In AD rats, PS treatment reduced the escape latent period of AD rats, increased SOD and OH(-), and decreased acetylcholinesterase levels (P < 0.05). Compared with PS 15 mg/kg, PS 30 mg/kg group was significantly more efficacious (P < 0.05). Compared with the AD model group, hippocampal cells showed normal arrangement, karyopyknosis decreased, and the pathological changes in the two PS groups were considerable. In conclusion, PS decreased cholinesterase, improved memory, and improved hippocampal inflammation injury in AD brains by increasing SOD and OH(-) levels.

Abstract
Trigeminal neuralgia is a sudden, severe condition characterized by stabbing and recurrent pain. Radiofrequency thermocoagulation (RFT) and pulsed radiofrequency (PRF) are common surgical interventions used to treat trigeminal neuralgia. This study aimed to investigate the therapeutic effects and associated complications of a combination of RFT and PRF in the treatment of trigeminal neuralgia. Computed tomography-guided percutaneous RFT of the Gasserian ganglion was performed on 80 patients with trigeminal neuralgia. Patients were randomly assigned to either group A (RFT at 70°C) or group B (RFT at 75°C). Patients in each group were divided into 2 subgroups, receiving percutaneous RFT (240 s) with or without PRF (42°C, 2 Hz, 240 s). Six months later, pain relief and complication status were evaluated. There was no significant difference in visual analogue scores among groups with RFT at 70° or 75°C, with or without PRF. Data showed that facial numbness and postoperative masticatory muscle weakness recovered more rapidly in patients receiving combined RFT and PRF treatment. Decreased corneal reflex was relieved to a significantly greater extent in groups receiving PRF than those without. Thus, compared to the use of RFT at 75°C alone, the combination of PRF and RFT helped eliminate postoperative complications, such as facial numbness, masticatory muscle weakness, and decreased corneal reflex, indicating that it could be useful for surgically treating trigeminal neuralgia.

Abstract
The sequence-characterized amplified region (SCAR) is a valuable molecular technique for the genetic identification of any species. This method is mainly derived from the molecular cloning of the amplified DNA fragments achieved from the random amplified polymorphic DNA (RAPD). In this study, we collected DNA from 10 species of Ganoderma mushroom and amplified the DNA using an improved RAPD technique. The amplified fragments were then cloned into a T-vector, and positive clones were screened, indentified, and sequenced for the development of SCAR markers. After designing PCR primers and optimizing PCR conditions, 4 SCAR markers, named LZ1-4, LZ2-2, LZ8-2, and LZ9-15, were developed, which were specific to Ganoderma gibbosum (LZ1-4 and LZ8-2), Ganoderma sinense (LZ2-2 and LZ8-2), Ganoderma tropicum (LZ8-2), and Ganoderma lucidum HG (LZ9-15). These 4 novel SCAR markers were deposited into GenBank with the accession Nos. KM391935, KM391936, KM391937, and KM391938, respectively. Thus, in this study we developed specific SCAR markers for the identification and authentication of different Ganoderma species.

Abstract
Dimocarpus longan Lour. is an edible and traditional herb in China, commonly referred to as longon. An improved randomly amplified polymorphic DNA (RAPD) protocol was here developed in order to determine the geographical origins of D. longan samples collected from 5 provinces in the southern and southwestern areas of China, including Sichuan, Hainan, Fujian, Guangdong, and Guangxi. Generally, the improved RAPD method generated good fingerprinting of the 5 samples using the selected 17 primers. In particular, primers SBS-A5, SBS-A13, SBS-I9, SBS-I20, SBS-M1, and SBS-Q12 produced distinguishable bands that clearly separated all 5 cultivars, suggesting that there are variations in RAPD genetic sites among the samples. The similarity index ranged from 0.69 to 0.76. The Sichuan and Hainan clades clustered together with a 0.73 similarity index. The Guangxi and Fujian clades clustered together with a 0.76 similarity index, and they formed the sister clade to the Sichuan/Hainan clade with a 0.71 similarity index. The Guangdong clade was in a basal polytomy with a 0.70 similarity index. Based on the abundant DNA polymorphisms, these longan accessions are distinguishable using our improved RAPD technique. Therefore, RAPD analysis is an effective technique in distinguishing the geographical origins of D. longan. Moreover, the improved method could also be employed for a variety of applications including genetic diversity and fingerprinting analyses.

Abstract
Ketamine is a dissociative anesthetic agent that has been widely used in surgery and for relieving pain in chronic cancer patients. We applied ketamine to breast cancer cell line MDA-MB-231 to detect the effect of treatment and molecular mechanisms involved. We found that ketamine can upregulate the level of anti-apoptosis protein Bcl-2, which promotes breast cancer cell invasion and proliferation. Knockdown of Bcl-2 could inhibit the increase of Bcl-2 and reduce the invasion and proliferation caused by ketamine in human breast cancer cells. Our findings provide new insight into the effects of ketamine in cancer treatment; we suggest that ketamine, which has been widely used in cancer operations and for relieving pain in chronic cancer patients, may be not the best choice because it can worsen the cancer through promotion of anti-apoptosis.

Abstract
Sludge with low organic content always results in an unsatisfactory performance, even failure of anaerobic digestion. The alkaline pretreatment effect on anaerobic digestion of sludge with low organic content has seldom been studied although it gives many benefits for sludge with high organic content. In this study the influence of alkaline pretreatment (pH 10, an effective alkaline pH) on the solubilization and methane production from waste activated sludge (WAS) with low organic content was investigated. Results from biochemical methane potential (BMP) experiments showed that anaerobic biodegradability of WAS was greatly improved by alkaline pretreatment at pH 10. Methane production from the current WAS under conditions of pretreatment time 4 h and digestion time 15 d was 139.6 mL/g VS (volatile solids), much higher than that from the unpretreated WAS with digestion time of 20 d (75.2 mL/g VS). Also, the solubilization of WAS was significantly accelerated by alkaline pretreatment. Mechanism exploration indicated that the general activities of anaerobic microorganisms, specific activities of key enzymes and the amounts of methanogens were enhanced by alkaline pretreatment at pH 10, showing good agreement with methane production.

Abstract
BACKGROUND To compare isoflurane anesthesia in patients with or without hyperbilirubinemia undergoing hepatobiliary surgery. METHODS Forty-two patients with obstructive jaundice and 40 control patients with normal liver function scheduled for hepatobiliary surgery under isoflurane anesthesia were studied. Anesthesia was induced with propofol (1.5-2 mg/kg) and remifentanil (2 microg/kg). After tracheal intubation, anesthesia was titrated using isoflurane in oxygen-enriched air, adjusted to maintain a bispectral index (BIS) value of 46-54. Ephedrine, atropine and remifentanil were used to maintain hemodynamic parameters within 30% of the baseline. The mean arterial blood pressure (MAP), heart rate (HR), drug doses and the time taken to recover from anesthesia were recorded. RESULTS Demographic data, duration and BIS values were similar in both groups. Anesthesia induction and maintenance were associated with more hemodynamic instability in the patients with jaundice and they received more ephedrine and atropine and less remifentanil and isoflurane (51.1+/-24.2 vs. 84.6+/-20.3 mg/min; P for all <0.05) than control patients. Despite less anesthetic use, the time to recovery and extubation was significantly longer than that in control. CONCLUSION Patients with obstructive jaundice have an increased sensitivity to isoflurane, more hypotension and bradycardia during anesthesia induction and maintenance and a prolonged recovery time compared with controls.

Abstract
BACKGROUND In this study, we compared liver function tests after hepatectomy with inflow occlusion as a function of propofol versus sevoflurane anesthesia. METHODS One hundred patients undergoing elective liver resection with inflow occlusion were randomized into a sevoflurane group or a propofol group. General anesthesia was induced with 3 μg/kg fentanyl, 0.2 mg/kg cisatracurium, and target-controlled infusion of propofol, set at a plasma target concentration of 4 to 6 μg/mL, or sevoflurane initially started at 8%. Anesthesia was maintained with target-controlled infusion of propofol (2-4 μg/mL) or sevoflurane (1.5%-2.5%). The primary end point was postoperative liver injury assessed by peak values of liver transaminases. RESULTS Transaminase levels peaked between the first and the third postoperative day. Peak alanine aminotransferase was 504 and 571 U/L in the sevoflurane group and the propofol group, respectively. Peak aspartate aminotransferase was 435 U/L after sevoflurane and 581 U/L in the propofol group. There were no significant differences in peak alanine aminotransferase or peak aspartate aminotransferase between groups. Other liver function tests including bilirubin and alkaline phosphatase, and peak values of white blood cell counts and creatinine, were also not different between groups. CONCLUSIONS Sevoflurane and propofol anesthetics resulted in similar patterns of liver function tests after hepatectomy with inflow occlusion. These data suggest that the 2 anesthetics are equivalent in this clinical context.

Abstract
BACKGROUND Some studies suggest that certain clinical symptoms of cholestasis, such as fatigue and pruritus, result from altered neurotransmission. Patients with obstructive jaundice also have labile blood pressure and heart rate. In the present study, the authors investigated whether obstructive jaundice affects a patient's sensitivity to hypnotics and the haemodynamic profile of propofol. METHODS Thirty-six ASA physical status I/II/III patients with serum total bilirubin (TBL) from 7.8 to 362.7 micromol/l scheduled for bile duct surgery were recruited. A computer-controlled propofol infusion programmed for effect site target was used to rapidly attain and maintain sequential increase of the compartment concentration (from 1 to 3 microg/ml). Each target-controlled concentration was maintained for about 12 min, and arterial blood samples were drawn for propofol concentration determination. The bispectral index (BIS) and mean arterial pressures (MAP) were used as indices of the propofol effect. The relation between the concentration and the effects was described by the Hill equation. The pharmacodynamic parameters were optimized using a nonlinear mixed-effect model. RESULTS TBL was not a significant covariate of EC(50) for the pharmacodynamic model. For BIS and MAP, the parameters of the pharmacodynamic model were E(max)=75.77%, EC(50)=2.34 microg/ml, and gamma=1.82, and E(max)=47.83%, EC(50)=1.49 microg/ml, and gamma=1.88, respectively. CONCLUSIONS We demonstrated that obstructive jaundice with serum TBL from 7.8 to 362.7 micromol/l had no effect on propofol pharmacodynamics observed by BIS and MAP.

Abstract
Since an outbreak of severe acute respiratory syndrome (SARS) was averted in 2004, many novel coronaviruses have been recognized from different species, including humans. Bats have provided the most diverse assemblages of coronaviruses, suggesting that they may be the natural reservoir. Continued virological surveillance has proven to be the best way to avert this infectious disease at the source. Here we provide the first description of a previously unidentified coronavirus lineage detected from wild Asian leopard cats (Prionailurus bengalensis) and Chinese ferret badgers (Melogale moschata) during virological surveillance in southern China. Partial genome analysis revealed a typical coronavirus genome but with a unique putative accessory gene organization. Phylogenetic analyses revealed that the envelope, membrane, and nucleoprotein structural proteins and the two conserved replicase domains, putative RNA-dependent RNA polymerase and RNA helicase, of these novel coronaviruses were most closely related to those of group 3 coronaviruses identified from birds, while the spike protein gene was most closely related to that of group 1 coronaviruses from mammals. However, these viruses always fell into an outgroup phylogenetic relationship with respect to other coronaviruses and had low amino acid similarity to all known coronavirus groups, indicating that they diverged early in the evolutionary history of coronaviruses. These results suggest that these viruses may represent a previously unrecognized evolutionary pathway, or possibly an unidentified coronavirus group. This study demonstrates the importance of systematic virological surveillance in market animals for understanding the evolution and emergence of viruses with infectious potential.

Abstract
OBJECTIVE The clinical differentiation between early Parkinson's disease (PD) and essential tremor (ET) could be difficult, therefore, the aim of this study was to investigate 99mTc-TRODAT-1 SPECT as an applicable tool in this field. METHODS 99mTc-TRODAT-1 single photon emission computed tomography (SPECT) was performed in 10 healthy volunteers, 27 patients with idiopathic PD (Hoehn and Yahr 1-1.5) and 12 patients with ET. The ratio of striatal (99m)Tc-TRODAT-1 binding was calculated as the index of (striatum - occipital cortex)/occipital cortex. RESULTS Compared with the striatal 99mTc-TRODAT-1 uptake in the ET group (0.49 +/- 0.07) or healthy controls (0.54 +/- 0.18), there was a significant decrease in the bilateral striatums of early PD, with a greater reduction in the contralateral striatum (0.27 +/- 0.08) than ipsilateral one (0.36 +/- 0.10, P < 0.01). Its sensitivity and specificity of differentiating early PD from ET was 96.4% and 91.7% respectively. CONCLUSION 99mTc-TRODAT-1 SPECT can detect the dysfunction of nigrostriatal system in patients with early PD and provided a feasible tool to help differentiate early PD from ET.

Abstract
Vanadyl sulfate (VOSO(4)) was given orally to 16 subjects with type 2 diabetes mellitus for 6 weeks at a dose of 25, 50, or 100 mg vanadium (V) daily [Goldfine et al., Metabolism 49 (2000) 1-12]. Elemental V was determined by graphite furnace atomic absorption spectrometry (GFAAS). There was no correlation of V in serum with clinical response, determined by reduction of mean fasting blood glucose or increased insulin sensitivity during euglycemic clamp. To investigate the effect of administering a coordinated V, plasma glucose levels were determined in streptozotocin (STZ)-induced diabetic rats treated with the salt (VOSO(4)) or the coordinated V compound bis(maltolato)oxovandium(IV) (abbreviated as VO(malto)(2)) administered by intraperitoneal (i.p.) injection. There was no relationship of blood V concentration with plasma glucose levels in the animals treated with VOSO(4), similar to our human diabetic patients. However, with VO(malto)(2) treatment, animals with low plasma glucose tended to have high blood V. To determine if V binding to serum proteins could diminish biologically active serum V, binding of both VOSO(4) and VO(malto)(2) to human serum albumin (HSA), human apoTransferrin (apoHTf) and pig immunoglobulin (IgG) was studied with EPR spectroscopy. Both VOSO(4) and VO(malto)(2) bound to HSA and apoHTf forming different V-protein complexes, while neither V compound bound to the IgG. VOSO(4) and VO(malto)(2) showed differences when levels of plasma glucose and blood V in diabetic rodents were compared, and in the formation of V-protein complexes with abundant serum proteins. These data suggest that binding of V compounds to ligands in blood, such as proteins, may affect the available pool of V for biological effects.

Abstract
The treatment of coking residual ammonia water has been a big difficult problem at home and abroad, and there is no breakthrough research achievement in the past. The invention patent "The method of treating all coking wastewater or treating coking residual ammonia water by flue gas" has been successfully used in Huaian Steel Works for high concentration and organic industry wastewater treatment. Not only can it realize the wastewater zero discharge, but also the wastewater treatment has an effect of de-sulfur and de-nitrogen for flue gas. So that the flue gas exhaust can meet the requirement of emission standard. The mass transfer and heat transfer, fly ash absorption and coagulation, acid and alkali neutralization reaction, catalysis oxidation and reduction reaction in flue gas would be the major factors.

Abstract
Hydrated molybdenum bronzes have been prepared by reduction reaction of MoO3 with NaBH4 in ethanol and DMSO. The reduction reactions in both solvents occur smoothly; thus, the layered structure of MoO3 is maintained in the product. Divalent cation Ca2+ has been intercalated between the MoO3 layers, which leads to highly reduced molybdenum bronze (Mo5.26+). Solvated molybdenum bronze catalyzes the reduction reaction of DMSO by NaBH4, producing CH3SCH3. The structure model of hydrated sodium molybdenum bronze has also been reinvestigated by using the Rietveld analysis. The hydrated molybdenum bronze crystallizes in an orthorhombic structure, in which the structure of Mo octahedron layers is closely related to that in MoO3. However, the structure refinement reveals that the Mo octahedron in the MoO3 layers is axially distorted, which is different from that in MoO3 but similar to an isoelectron compound H0.33MoO3.

Abstract
OBJECTIVE To investigate the effect of soft tissue repairing at different times on the union of type III b tibial fracture. METHODS From January 1987 to January 1999, seventy-six type III b tibial fractures were divided into 3 groups: early group(0 to 7 days), subacute group(8 to 30 days), late group(more than 30 days) according to the time of soft tissue repairing. The morbidity rates of complications such as infection, nonunion as well as the time to union were compared respectively. RESULTS Followed up for 10 to 36 months (averaged 24 months), the infection and nonunion rates of early group were lower than that of subacute and late groups(P < 0.01), the average time of fracture union of early group was less than that of subacute and late groups. CONCLUSION Early soft tissue repairing can decrease the complications and the time to union of Type III b tibial fracture obviously. The time of "early" should be limited in one week and as soon as possible.

Abstract
This is the first inn vitro study on the activity of 20 kinds of crude extracts of traditional Chinese medicine (TCM) on the intestinal parasite, Blastocystis hominis using the criteria of living cell count (LCC) and living cell rate (LCR). LCC and LCR were applied as observation indicators, the former as a fixed-quantity and the latter as a fixed-quality method. LCR calculated percentage rate of living cells using eosin-brilliant cresyl blue staining which could differentiate between living cells and dying or dead cells. There were five extracts with no inhibitory activity, thirteen with moderate inhibition and two with high inhibition. The crude extracts of Coptis chinensis (CC) and Brucea javanica (BJ) were found to be most active against B. hominis. The active concentration of CC was 100 micrograms/ml. The active concentration of BJ was 500 micrograms/ml. The active concentration of metronidazole (MD) was 10 micrograms/ml and this was taken as an active standard drug for B. hominis.

Abstract
We have developed a cell model for loss of differentiated gene expression in cellular aging. Over long periods in culture, bovine adrenocortical cells lose expression of a specialized gene, steroid 17 alpha-hydroxylase. The decline in expression of 17 alpha-hydroxylase in mass cultures and clones of bovine adrenocortical cells is the result of a phenotypic switching process which yields a mixture of cells that can express 17 alpha-hydroxylase after induction with cyclic AMP and cells that are incapable of expression of 17 alpha-hydroxylase. In the experimental portion of the work, bovine adrenocortical cells were grown in culture in colonies, stimulated with cyclic AMP to induce 17 alpha-hydroxylase, then fixed and hybridized in situ with labeled 17 alpha-hydroxylase cDNA. Separate images of Giemsa-stained cell colonies and of their hybridization patterns were digitized and combined as stylized representations of the colonies for comparison with those produced by a computer simulation. A program for the simulation of growth of colonies of bovine adrenocortical cells in senescence with phenotypic switching of 17 alpha-hydroxylase is presented. Comparison between simulated colonies and real colonies shows that the model accurately simulates colony growth and phenotypic switching. It suggests that the probability of phenotypic switching per cell generation is in the range of 0.03 to 0.06. The major variable among colonies is division probability, consistent with observations in this and other cell culture systems that clones differ widely in replicative potential. Thus, phenotypic switching of 17 alpha-hydroxylase in adrenocortical cells may be modelled using simple assumptions.

Abstract
Recent experiments in cultured bovine adrenocortical cells show that the previously observed phenotypic switching of CYP17 (steroid 17 alpha-hydroxylase) expression is preceded at a much earlier time by changes in methylation in the CYP17 5' flanking region. Two CpG sites that are methylated in the adrenal cortex in vivo were observed to undergo rapid demethylation when adrenocortical cells were placed in culture. Two adjacent CpG sites that are also methylated in vivo did not demethylate; these two sites are completely nonmethylated in fibroblasts. All CpG sites downstream, in the promoter or coding region, are always methylated in all tissues and in bovine adrenocortical cells even after many population doublings in culture. In contrast to the specific and rapid demethylation of sites in CYP17, satellite I shows a slower and apparently random loss of methylation that extends over the entire replicative life span. These changes in methylation provide examples of genetic instability in cells that undergo senescence in culture. Future experiments will focus on the relationship of these events to the phenotypic switching process.

Abstract
In bovine adrenocortical cells senescing in culture, the decline in expression of cyclic AMP-inducible 17 alpha-hydroxylase in mass cultures and clones of bovine adrenocortical cells results from a decrease in the number of cells in the population capable of expressing this gene. As the population of cells decreases in proliferative potential, the fraction of the population that expresses 17 alpha-hydroxylase after induction with cyclic AMP decreases, until the population comprises entirely nonexpressing cells. We used in situ hybridization to study the relationship between the loss of the ability to replicate and the loss of expression of this differentiated function gene. Colonies of cells from early passage cultures comprised complex mosaics of expressing and nonexpressing cells, indicating a high-frequency switching event. At an individual cell level, there was a complete independence of replicative senescence and loss of 17 alpha-hydroxylase expression. Groups of cells with a morphology characteristic of replicative senescence, occurring frequently in early-passage cultures, comprised both expressing and nonexpressing cells, as did cells that appeared to be in rapid growth. This was confirmed by prior incubation of cells with bromodeoxyuridine to label cycling cells; both cycling and noncycling populations comprised mixtures of expressing and nonexpressing cells. In contrast, replication was required for the loss of 17 alpha-hydroxylase expression, since cells rendered incapable of division by treatment with mitomycin C maintained 17 alpha-hydroxylase expression over long time periods. Thus, the process that results stochastically in replicative senescence and the process that results in loss of 17 alpha-hydroxylase expression are independent, but they have similar time-courses and both require replication for phenotypic switching to take place.
