Abstract
Oxygen is one of the determinants of root microbiome formation. However, whether plants regulate rhizosphere oxygen levels to affect microbiota composition and the underlying molecular mechanisms remain elusive. The receptor-like kinase (RLK) family member FERONIA modulates the growth-defense tradeoff in Arabidopsis. Here, we established that rice FERONIA-like RLK 7 (FLR7) controls rhizosphere oxygen levels by methylene blue staining, oxygen flux, and potential measurements. The formation of oxygen-transporting aerenchyma in roots is negatively regulated by FLR7. We further characterized the root microbiota of 11 FLR mutants including flr7 and wild-type Nipponbare (Nip) grown in the field by 16S ribosomal RNA gene profiling and demonstrated that the 11 FLRs are involved in regulating rice root microbiome formation. The most abundant anaerobic-dependent genus Anaeromyxobacter in the Nip root microbiota was less abundant in the root microbiota of all these mutants, and this contributed the most to the community differences between most mutants and Nip. Metagenomic sequencing revealed that flr7 increases aerobic respiration and decreases anaerobic respiration in the root microbiome. Finally, we showed that a representative Anaeromyxobacter strain improved submergence tolerance in rice via FLR7. Collectively, our findings indicate that FLR7 mediates changes in rhizosphere oxygen levels and enriches the beneficial dominant genus Anaeromyxobacter and may provide insights for developing plant flood prevention strategies via the use of environment-specific functional soil microorganisms.

Abstract
Digital financing is an emerging source after COVID-19 to address novel problems of economies and different industries. With the growing concern about the sustainability of the global environment, developing countries are now moving toward unprecedented economic development. This research analyzes the impact of digital finance and economic growth on environmental sustainability in China from 1995 to 2020, focusing on natural resource management. To include asymmetric patterns and handle socioeconomic shocks during the last three decades, the research uses the cutting-edge ordinary least square (O.L.S.) methodology. The O.L.S. helps the research findings and illustrated patterns of ecological sustainability dependency across various data distributions. According to the empirical results, N.R., F.D.P., and G.D.P. all benefited from carbon emissions at higher and lower emissions quantiles. Green technology innovation, on the other hand, considerably reduces emissions across all quantiles. Notably, the effect of each repressor significantly changed for lower, medium, and higher emissions quantiles, showing a thorough understanding of China's resource scarcity and sustainable growth.

Abstract
Objective: This study aims to analyze the incidence, disease burden, and trend of intraocular foreign bodies in China from 1990 to 2019, and to analyze the trend of changes in age, period, and cohort of Chinese men. Methods: The data related to the incidence rate and disease burden of intraocular foreign bodies in China from 1990 to 2019 were obtained from the Global Burden of Disease Database (GBD database) on the website of the Institute for Health Indicators and Evaluation (IHME) of the University of Washington, United States, and the annual percentage rate change (AAPC) of intraocular foreign bodies in China was calculated using the Joinpoint software to describe the long-term trend of their incidence rate and disease burden over time. Using Stata17 software, an age period cohort model was constructed to analyze the age, period, and cohort factors affecting intraocular foreign bodies in men. Results: In 2019, the incidence rate of intraocular foreign bodies in China was 791.20/100 000, and the DALY rate was 10.32/100 000, with an average annual decline rate of 1.70% and 1.48% respectively. In 2019, the number of cases of intraocular foreign bodies in China was 11.253 6 million, and the DALY was 1 812.29 million person years. Among them, the incidence and disease burden of intraocular foreign bodies in men were more severe than those in women, and the incidence and disease burden risk of intraocular foreign bodies in men aged 30-35 and 45-50 were the highest. The incidence and disease burden risk of intraocular foreign bodies in elderly men gradually increased. Conclusions: As a common ophthalmic disease, the incidence of intraocular foreign bodies and the DALY rate are declining, but the disease burden is increasing. With the aging of the population, the incidence of intraocular foreign bodies in the elderly will further increase in the future, which should be considered by policy makers. The findings of this study can help governments and healthcare planners formulate practical and targeted policy responses.

Abstract
SO2, a gas signaling molecule, can be produced endogenously in mitochondria. Its hydrolysate, HSO3-, plays a key role in food preservation, cardiovascular relaxation, and other fields, suggesting that it is important to achieve its detection. Here, based on the Michael addition mechanism, four hemicyanine dye fluorescent probes (ETN, ETB, STB, and EIB) were designed and synthesized for responding to HSO3-. We evaluated the reaction ability of different probes with HSO3- and tried to explain the reasons for the significantly different response effects between probes and HSO3- according to the structure-activity relationship. The influence of different substituents of probes on the properties of mitochondria-targeting was also discussed. Finally, we screened out ETN as the optimal HSO3- probe due to its high sensitivity, rapid reactivity, and good mitochondria-targeting, and it could sensitively respond to HSO3- in living cells. The LODs of ETN for HSO3- were calculated by both absorption and fluorescence methods, respectively, which were 2.727 and 0.823 μM. Our work provided valuable references for designing strategies and potential tools for response to SO2 derivatives in biosystems.

Abstract
Objective: To investigate the spontaneous nystagmus (SN) and the frequency characteristics of affected semicircular canals in patients with vestibular neuritis (VN). Methods: This is a cross-sectional study. A total of 61 patients with VN admitted to the Department of Neurology of Shanxi Bethune Hospital from June 2020 to October 2021, 39 were male and 22 were female, with a mean age of (46±13) years old and male to female ratio of 1.77∶1. According to SN characteristics, 61 patients were divided into non-nystagmus group(nSN), horizontal nystagmus group(hSN) and horizontal-torsional nystagmus group (htSN). Clinical data were collected, and SN, unilateral weakness (UW), directional preponderance (DP), and video head impulse test (vHIT) gain were used as observation indicators. Statistical analysis by SPSS23.0 software. Normal distributed quantitative data (age, semicircular canal gain, SN intensity) were expressed by x¯±s, non-normal distributed quantitative data (disease course, UW, DP) were expressed by M(Q1,Q3), qualitative data were expressed by rate and composition ratio, difference analysis by one-way ANOVA, rank sum test, Chi-square test or Fisher's exact probability method, considered by P value<0.05. Results: (1)The disease course of nSN, hSN and htSN was 7.0 (4.0, 12.5), 6.0 (3.5, 11.5), and 3.0 (2.0, 6.5) days respectively, and there were statistical differences (χ2=7.31,P=0.026).(2)The horizontal nystagmus intensity of htSN was (16.8±8.6)°/s, which was significantly higher than that of (9.8±4.7)°/s in hSN (t=3.71, P<0.001). There was no significant difference in the positive rate of UW between the three groups (P=0.690), and there was a significant difference in the positive rate of DP in the three groups (χ2=12.23, P=0.002). The horizontal nystagmor intensity in the htSN was positively correlated with the vertical nystagmus intensity (r=0.59, P=0.001).(3)The gain of the affected horizontal canal of the three groups was statistically different (F=8.28, P=0.001), and the gain of the horizontal canal of hSN and htSN was significantly lower than that of nSN (t=2.74, P=0.008; t=4.05, P<0.001); The gain of the affected anterior canal in the three groups was statistically different (F=5.32, P=0.008). The gain of the anterior canal in both nSN and hSN was significantly higher than that in htSN (t=3.09, P=0.003; t=2.15, P=0.036). The horizontal canal gain of htSN is positively correlated with the anterior canal gain (r=0.74, P<0.001).(4)The affected semicircular canals in the two groups with no-vertical-component nystagmus (nSN and hSN) and the htSN were counted. The composition ratio of the affected semicircular canals in the two groups was different (χ2=8.34, P=0.015). Conclusion: The occurrence of SN in patients with VN is related to many factors, such as the disease course, low and high frequencies, and the severity of the condition in the affected semicircular canal.

Abstract
Objective: To investigate the association between serum sex hormone-binding globulin (SHBG) and non-alcoholic steatohepatitis (NASH). Methods: In this cross-sectional study, a total of 371 middle-aged and young obese patients who were hospitalized and underwent liver puncture in Nanjing Drum Tower Hospital from January 2016 to April 2021 were included. The population was divided into control group (n=43) and non-alcoholic fatty liver disease (NAFLD) group (n=328) based on the non-alcoholic fatty liver disease activity score. Subjects in NAFLD group were further divided into non-alcoholic fatty liver (NAFL) (n=60), uncertain-NASH (n=172), and NASH (n=96). Serum SHBG was tested in patients with NAFLD who were divided into three subgroups according to tertiles. The liver pathological characteristics in different SHBG level subgroups were compared. The risk factors of NASH were analyzed by logistic regression. The prediction model of NASH noninvasive diagnosis was established by forward stepwise regression, and the diagnostic value of non-invasive model for NASH was evaluated by receiver operating characteristic (ROC) curve. Results: The median age in patients were (32±10) years old with a body mass index of (39.16±6.58) kg/m², including 236 females (63.6%). Serum SHBG level [M (Q1, Q3)] in NAFLD group was significantly lower than that in control group [16.90 (11.43, 23.00) vs. (23.45 (15.40, 31.22) mmol/L, P<0.05], and progressively diminished in NAFL, uncertain-NASH and NASH subgroups [(22.24±10.47), (20.57±19.58), (15.80±8.74) mmol; P for trend<0.05]. Compared with the high-leveled SHBG subgroup, the steatosis score (2.09±0.80 vs. 1.51±0.72, P<0.01) and lobular inflammation score (1.10±0.68 vs. 0.85±0.68, P<0.05) were significantly higher in the low-leveled SHBG group. Multivariate logistic regression analysis indicated that lower serum SHBG level was an independent risk factor for NASH (OR=2.527, 95%CI: 1.296 to 4.928, P<0.05). The area under ROC curve of SHBG combined with aspartate aminotransferase in predicting NASH in NAFLD patients was 0.752 (95%CI: 0.696 to 0.809). Conclusion: Low serum SHBG level is associated with NASH.

Abstract
BACKGROUND In mirror-image dextrocardia, the anterior-posterior position of the cardiac chambers and great vessels is maintained, but the left-right orientation of the abdominal organs is reversed. The abnormal anatomy of the heart poses surgical challenges and problems in dealing with surgical risk and monitoring complications. There are few reports on closure of the left atrial appendage (LAA) in dextrocardia and no reports on the application of enhanced recovery after surgery (ERAS) following LAA occlusion (LAAO) procedures.
CASE SUMMARY The objective for this case was to ensure perioperative safety and accelerate postoperative recovery from LAAO in a patient with mirror-image dextrocardia. ERAS was guided by the theory and practice of nursing care. Atrial fibrillation was diagnosed in a 77-year-old male patient, in whom LAAO was performed. The 2019 guidelines for perioperative care after cardiac surgery recommend that the clinical nursing procedures for patients with LAAO should be optimized to reduce the incidence of perioperative complications and ensure patient safety. Music therapy can be used throughout perioperative treatment and nursing to improve the anxiety symptoms of patients.
CONCLUSION The procedure was uneventful and proceeded without complications. Anxiety symptoms were improved.

Abstract
Nasopharyngeal carcinoma (NPC) is a common malignancy in Southern China and Southeast Asia. Radiotherapy is the main treatment option. However, radiotherapy does not benefit all patients because there is no known precise biomarker that can be used for screening radioresistant patients. Genetic predisposition is closely related to tumor development, therapeutic response, and prognosis. The relationship between regenerating gene IA (REGIA) and NPC is unclear. This study aimed to retrospectively analyze the association between REGIA expression and metastasis, radiosensitivity, and survival in patients with NPC as well as assess the effect of radiation on REGIA expression in vitro. Immunohistochemical staining was used to detect REGIA. The relationship between REGIA expression in radioresistant NPC and the prognosis of CNE1 NPC cells were analyzed using quantitative real-time polymerase chain reaction and Western blotting. We found that increased doses of radiation in CNE1 cells significantly decreased REGIA expression (P<0.05). The overall rate of REGIA-positive expression was 47.15% in NPC tissues and 45.00% and 61.02% in radiosensitive and radioresistant cases, respectively, showing significant differences (P<0.05). A REGIA-positive protein expression rate had a negative correlation with radiosensitivity in NPC (r= -0.109, P=0.047). Both REGIA-positive and REGIA-negative expression strongly predicted the overall survival rate and progression-free survival of NPC patients (P<0.01). A multivariate analysis indicated that REGIA was an inverse prognostic factor in NPC patients (REGIA-positive expression: hazard ratio (HR)=2.139, 95% confidence interval (CI)=1.56-2.94, P<0.001 and REGIA-negative expression: HR=1.958, 95% CI=1.42-2.69, P<0.001). In conclusion: Radiation can affect REGIA expression. The REGIA expression level correlated with radioresistance and a poor prognosis. In addition, REGIA expression might act as a potential therapeutic target and prognostic predictor in NPC patients.

Abstract
Objective Gene polymorphism is closely related to tumor development, therapeutic response and prognosis. The relationship between regenerating gene 1A (Reg1A) polymorphism and nasopharyngeal carcinoma (NPC) is unclear. This retrospective study aimed to analyze the association between Reg1a polymorphisms and metastasis, radiation sensitivity and survivals in patients with NPC. Methods A total of 308 patients who had received radiotherapy at the Affiliated Xinhua Hospital, Hainan Medical College, between January 2010 and December 2018 with NPC, were enrolled for assessment of Reg1a polymorphisms through direct DNA sequencing. Results In the polymorphism of gene REG1A, patients with rs10165462 20CC genotype had later T stages (OR = 4.051, 95% CI: 1.775–9.244, P = 0.001), whereas carriers with rs12072 2922CC genotype had earlier T stages (OR = 1.891, 95% CI: 1.018–3.514, P = 0.044) after adjustments for age and gender, respectively. Among rs10165462 20 C/T polymorphism, 20TT wild-type was associated with better radiation response (P = 0.0019), and multivariate analysis showed that it was the only genotype of polymorphism that was significantly associated with better radiation response (OR = 0.265, 95% CI: 0.096–0.727, P = 0.01). Patients with the 20TT wild-type had a better five-year overall survival (60.9%) rate and five-year progression-free survival (60.8%) than those with the 20CC genotype (41.8% and 39.4%, P = 0.01 and P = 0.004, respectively). Patients with variant alleles (CC + CT) had significantly poorer OS (45.2%) and PFS (41.8%) compared with wild-type (TT) carriers (60.9% and 60.8%; P = 0.037 and P = 0.015, respectively). As for rs12072, patients with variant alleles (TT + TC) had significantly adverse OS and PFS compared with wild-type (CC) carriers (62.5% vs 44.8% and 62.5% vs 42.9%; P = 0.024 and P = 0.027, respectively). Cox regression showed that rs10165462 20CT was the only prognostic factor for OS (HR = 1.642, 95% CI 1.038–2.598, P = 0.034) and PFS (HR = 1.705, 95% CI 1.080–2.692, P = 0.022). Conclusion Reg1a polymorphisms may be a predictor of radiation response, local invasion, OS and PFS in patients with NPC who undergo radiotherapy treatment.

Abstract
Garlic (Allium sativum L.) and its constituents have been shown to modify rumen fermentation and improve growth performance. Garlic skin, a by-product of garlic processing, contains similar bioactive components as garlic bulb. This study aimed to investigate the effects of garlic skin supplementation on growth performance, ruminal microbes, and metabolites in ruminants. Twelve Hu lambs were randomly assigned to receive a basal diet (CON) or a basal diet supplemented with 80 g/kg DM of garlic skin (GAS). The experiment lasted for 10 weeks, with the first 2 weeks serving as the adaptation period. The results revealed that the average daily gain and volatile fatty acid concentration were higher (P < 0.05) in lambs fed GAS than those in the CON group. Garlic skin supplementation did not significantly (P > 0.10) affect the α-diversity indices, including the Chao1 index, the abundance-based coverage estimator value, and the Shannon and Simpson indices. At the genus level, garlic skin supplementation altered the ruminal bacterial composition by increasing (P < 0.05) the relative abundances of Prevotella, Bulleidia, Howardella, and Methanosphaera and decreasing (P < 0.05) the abundance of Fretibacterium. Concentrations of 139 metabolites significantly differed (P < 0.05) between the GAS and the CON groups. Among them, substrates for rumen microbial protein synthesis were enriched in the GAS group. The pathways of pyrimidine metabolism, purine metabolism, and vitamin B6 metabolism were influenced (P < 0.05) by garlic skin supplementation. Integrated correlation analysis also provided a link between the significantly altered rumen microbiota and metabolites. Thus, supplementation of garlic skin improved the growth performance of lambs by modifying rumen fermentation through shifts in the rumen microbiome and metabolome.

Abstract
Objective: To explore the clinical characteristics of interrupted of the inferior vena cava with azygous continuation and the prognosis. Methods: Retrospective analysis of 21 fetuses diagnosed with interrupted inferior vena cava with azygous continuation among 28 567 pregnant women who underwent routine ultrasound scan. The clinical data, ultrasonographic features, genetic information and prognosis were collected. Results: Interrupted of the inferior vena cava with azygous continuation occurred in 21(0.07%, 21/28 567) of 28 567 patients. Three fetuses (14%, 3/21) complicated with heart and extracardiac malformations, including endocardiac cushion defect, single atrium and single ventricle, double superior vena cava, dextrocardia, asplenia syndrome, visceral heterotaxy, duodenal atresia; six fetuses (29%, 6/21) were associated with cardiac anomalies, such as hypoplastic left heart syndrome, double outlet right ventricle, pulmonary stenosis, ventricular septal defect, persistent left superior vena cava, endocardiac cushion defect and transposition of the great arteries; six cases (29%, 6/21) were only combined with extracardiac malformations, includingasplenia syndrome, visceral heterotaxy, duodenal atresia. Three fetuses (14%, 3/21) were nonorganic abnormalities included thickening of the right ventricle wall, fetal bradycardia, pericardial effusion, hydrops abdominis, increased peak systolic velocity/end diastolic velocity and single umbilical artery. Three fetuses (14%, 3/21) were isolated interrupted inferior vena cava with azygous continuation, but without other anomalies and 2 of them had normal fetal karyotype. Five cases (24%, 5/21) were successfully vaginal delivery, 1 case (5%, 1/21) had cesarean section. After 12-40 months follow-up, we didn't obeserve obviously abnormality, nor any chromosomal abnormality. Ten patients (48%, 10/21) opted for termination of the pregnancy and the autopsies were not done. Five cases (24%, 5/21) were lost to follow up. Conclusions: Interrupted inferior vena cava with azygous continuation are associated with cardiovascular and extracardiac anomalies, cardiac malformation and visceral heterotaxy are the most common anomalies. Visceral heterotaxy should be considered and fetal karyotype should be suggested. In the cases of isolated interrupted inferior vena cava with azygous continuation and normal karyotype, the outcome is favorable.

Abstract
BACKGROUND Recent studies indicated that insulin resistance may contribute to the pathogenesis of polycystic ovary syndrome (PCOS); however, the specific mechanism is still unclear. OBJECTIVE To investigate the effect of sodium aescinate (SA) on PCOS-IR rat models. METHODS Sixty rats were randomly divided into the five groups: un-treated rats (n = 12), PCOS-IR group (n = 12), PCOS-IR group plus 50 mg/kg SA (n = 12), PCOS-IR group plus 10 mg/kg SA (n = 12), PCOS-IR group plus 150 mg/kg metformin (n = 12). On day 21, rats were sacrificed, and H(and)E staining was performed for histopathologic examination of the ovaries; moreover, the serum level of follicle-stimulating hormone (FSH), testosterone, and luteotropic hormone (LH) were measured, and the expression as well as phosphorylation of PI3K, Akt and Gsk-3β were examined using western blot assay. RESULTS High dosage of SA treatment improved the morphological features of the ovaries in PCOS rats, and also induced significant decrease in serum expression of testosterone and LH/FSH ratio and significant decrease in the expression of p-PI3K, p-Akt and p-Gsk-3β. CONCLUSION Our results demonstrated that SA treatment could alleviate the symptom of PCOS in rat model through regulating the PI3K/Akt/GSK3-β pathway (Fig. 4, Ref. 22).

Abstract
Ujumqin sheep are susceptible to infection by the gastrointestinal nematode Haemonchus contortus, which reduces productivity and total meat yield in sheep. Thus, the effects of green tea polyphenol (GTP) supplements (0, 2, 4, or 6g of GTP/kg feed) on dietary nutrient digestibility and meat quality in lambs infected with H. contortus were examined; control lambs were not infected. H. contortus infections did not affect digestion but the apparent digestibilities of nutrients were decreased by dietary 2g of GTP/kg feed supplementation. There was an interaction between treatment and sampling time on plasma total protein, urea nitrogen, and amino acid concentrations. The antioxidant activity and meat color of INFGTP0 lambs decreased. In conclusion, H. contortus infections in lambs decreased meat quality, but appropriate levels of dietary GTP supplementation diminished these negative effects though lower dose of GTP supplement showed negative effects on digestion.

Abstract
To explore the effects of straw mulching on soil moisture and yield of watermelon, corn straw was used as mulching materials, and three straw mulch treatments were performed, i. e., whole mulch (WM), rows mulch (SM) and root domain mulch (RM), and non-mulching as control. The results indicated that WM and RM treatments increased significantly soil water storage in 0-120 cm of soil layer under root domain and rows compared with the control during watermelon growth period, and soil water storage of RM was higher than that of SM after growing tendril. Effects of all straw mulch treatments on soil moisture were most obvious from watermelon post-growing tendril to pre-swelling and maturity. With the growth and development of watermelon, the three straw mulch treatments improved soil moisture around root domain, resulting in increased watermelon yields. Compared with the CK, the WM, SM and RM treatments significantly improved the yield and the water use efficiency of watermelon by 24.8%, 11.5% and 15.1%, and 42.7%, 24.3% and 29.4%. The WM with 13500 kg x hm(-2) straw was recommended for watermelon production in arid areas due to its favorable effect on soil storage moisture, yield and water use efficiency.

Abstract
Direct inhibitory effects of tannic acid on Haemonchus contortus viability were studied in vitro using the larval migration inhibition (LMI) assay. Sheep white blood cells (WBC) were preincubated with 5 and 50 lg/mL tannic acid or not followed by whole H. contortus antigen (WHA). Cells were harvested at 24 h post-incubation to test host immune responses. Concentrations of 50, 100, 500, 1000, 3000 and 5000 lg/mL tannic acid inhibited larvae migration by 19.8, 42.4, 46.3, 92.0, 93.7 and 100%, respectively, within 96 h post-incubation (P < 0.001). The relative mRNA levels of interferon (IFN)-c, interleukin (IL)-2, IL-4 and IL-10 were increased by WHA stimulation without tannic acid. However, the increased effects on IFN-c and IL-2 were inhibited by tannic acid preincubation (P < 0.001), while the increases in IL-4 and IL-10 were greatly enhanced by tannic acid preincubation (P < 0.001). Changes in protein levels of all cytokines essentially paralleled the changes in their corresponding mRNA levels. In conclusion, tannic acid is directly harmful to larvae in a dose- and time-dependent manner and modulates immune responses of sheep WBC stimulated by H. contortus antigen by inhibiting Th1 cytokines and increasing Th2 cytokine expression in vitro.

Abstract
Ophiocordyceps sinensis, one of the most important income sources of rural Tibetan families, is an entomopathogenic fungus that parasitizes the ghost moth Thitarodes larvae, which live in alpine meadows on the Tibetan Plateau and in the Himalayas. The annual yield of O. sinensis has gradually declined in recent years. However, there is no effective method to sustain or increase the yield of O. sinensis artificially because the life cycle of the O. sinensis anamorph remains unclear. Here we detected O. sinensis in alpine plant roots by nested-touchdown polymerase chain reaction (PCR). Forty-two alpine plant species were screened. The roots from 23 alpine plant species (54.76%) tested positive including 13 families and 18 genera. The detection results indicate that O. sinensis is present in the plant roots during the anamorph life cycle, to deal with harsh conditions in alpine habitats and have an increased opportunity to infect the larvae. The finding provides new information regarding the biology and ecology of O. sinensis that may be used to sustain this valuable resource.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried succulent stem of Cistanche tubulosa (Schenk) R. Wight is one component of traditional Chinese medicine prescriptions for diabetes. However, there have been no modern scientific reports to confirm this traditional claim for the Cistanche species until now. Thus, we investigated the effects of Cistanche tubulosa on glucose homeostasis and serum lipids in male BKS.Cg-Dock7(m) +/+ Lepr(db)/J (db/db) mice, a model of type 2 diabetes. MATERIALS AND METHODS The verbascoside and echinacoside contents of Cistanche tubulosa powder were evaluated using HPLC. The total phenolic content, polysaccharide content and antioxidant activity of Cistanche tubulosa powder were also evaluated. Then, different doses of Cistanche tubulosa (equivalent to 120.9, 72.6 or 24.2mg verbascoside/kg) were administered orally once daily for 45 days to male db/db mice. Age matched db/+ mice were used as normal controls. Body weight, fasting blood glucose, postprandial blood glucose and insulin tolerance test were measured during the experiment. At the time of sacrifice, blood was collected for measurement of insulin level, the homeostatic model assessment of insulin resistance (HOMA-IR), and total cholesterol, triglyceride, HDL-c, LDL-c and VLDL-c levels; liver and muscle were harvested for measurement of glycogen levels. RESULTS Cistanche tubulosa significantly suppressed the elevated fasting blood glucose and postprandial blood glucose levels, improved insulin resistance and dyslipidemia, and suppressed body weight loss in db/db mice. However, Cistanche tubulosa did not significantly affect serum insulin levels or hepatic and muscle glycogen levels. CONCLUSION This study provides scientific evidence for the traditional use of Cistanche tubulosa to treat diabetes, suggesting that Cistanche tubulosa has the potential for development into a functional food ingredient or drug to prevent hyperglycemia and treat hyperlipidemia.

Abstract
This study aimed to evaluate testicular toxicity induced by hydroxyurea (HU) and the possible counteracting effect of an aqueous extract of Cistanche deserticola (CD). HU is an antineoplastic drug that has potential reproductive toxicity, and Herba Cistanche has been used as a tonic for the reproductive system for thousands of years. Sixty mice were randomly divided into five groups. Except mice in normal group, the rest received HU (400 mg kg(-1) body weight) intragastrically. Meanwhile, mice in normal and HU control groups received purified water, and the rest received intragastrically three doses of CD decoctions (1.5, 3.0 and 6.0 g crude drug kg(-1) body weight, respectively) daily for 4 weeks. Severe testes lesions were observed, testes weight (P<0.01) and serum luteinising hormone levels (P<0.01) were also decreased significantly, in the HU groups. Three doses of CD decoctions alleviated the spermatogenetic cell degeneration induced by HU and modulated the serum sex hormones levels to some extent.

Abstract
UNLABELLED The use of bisphosphonates and the risk of esophageal cancer have recently received increasing concern and related studies have yielded controversial results. The present meta-analysis of observational studies shows that no clear association between bisphosphonate treatment and risk of esophageal cancer was observed. INTRODUCTION Epidemiological evidence suggests that bisphosphonate treatment can increase the risk of esophageal cancer. However, data on this issue are unstable and controversial. We conducted a meta-analysis to provide a quantitative assessment of the association between use of bisphosphonates and risk of esophageal cancer. METHODS We searched the Medline and Embase databases up to May 2012 to identify studies related to bisphosphonates and esophageal cancer. Summary effect estimates with 95 % confidence intervals (CI) were derived using a fixed or random effects model, depending on the heterogeneity of the included studies. RESULTS Seven epidemiologic studies that consisted of four cohort studies and three case-control studies were included in this meta-analysis. In our primary analysis, bisphosphonate treatment was not associated with risk of esophageal cancer in both cohort studies [pooled relative risk (RR) 1.23, 95 % CI 0.79-1.92] and case-control studies [pooled odds ratio (OR) 1.24, 95 % CI 0.98-1.57]. Evidence for the presence of significant heterogeneity was found in cohort studies (p = 0.009, I (2) = 74 %) but not in case-control studies (p = 0.338, I (2) = 7.8 %). In our secondary analysis, no significant increased risk of esophageal cancer was found in alendronate users (pooled RR 1.08, 95 % CI 0.67-1.75 in cohort studies; pooled OR 1.16, 95 % CI 0.82-1.63 in case-control studies). CONCLUSIONS Based on current evidences, bisphosphonate treatment was not significantly associated with excess risk of esophageal cancer.

Abstract
The G-quadruplex ligands database (G4LDB, http://www.g4ldb.org) provides a unique collection of reported G-quadruplex ligands to streamline ligand/drug discovery targeting G-quadruplexes. G-quadruplexes are guanine-rich nucleic acid sequences in human telomeres and gene promoter regions. There is a growing recognition for their profound roles in a wide spectrum of diseases, such as cancer, diabetes and cardiovascular disease. Ligands that affect the structure and activity of G-quadruplexes can shed light on the search for G-quadruplex-targeting drugs. Therefore, we built the G4LDB to (i) compile a data set covering various physical properties and 3D structure of G-quadruplex ligands; (ii) provide Web-based tools for G-quadruplex ligand design; and (iii) to facilitate the discovery of novel therapeutic and diagnostic agents targeting G-quadruplexes. G4LDB currently contains >800 G-quadruplex ligands with ∼4000 activity records, which, to our knowledge, is the most extensive collection of its kind. It offers a user friendly interface that can meet a variety of data inquiries from researchers. For example, ligands can be searched for by name, molecular properties, structures, ligand activities and so on. Building on the reported data, the database also provides an online ligand design module that can predict ligand binding affinity in real time.

Abstract
A field experiment was conducted to study the effects of full period and growth period straw mulching with an amount of 3000, 6000, and 9000 kg x hm(-2) on the soil aggregates in a no-tillage dryland wheat field in Weibei Loess Pleateau of Shaanxi Province, taking no full period straw mulching as the control. In the 0-40 cm soil layer, the content of > 5 mm aggregates increased with depth, while that of <5 mm aggregates was in adverse. Under straw mulching, the total contents of > 0.25 mm mechanical stable aggregates (DR0.25) and of > 0.25 mm water stable aggregates (WR0.25) were significantly higher than the control, with an increase of 13.0%-26.4% and 18.6%-45.6%, respectively and the largest increment in the treatment 6000 kg x hm(-2) of straw mulching. Straw mulching increased the soil organic matter content, and the latter had a significant positive correlation with the WR0.25 content. All the straw mulching treatments decreased the soil unstable aggregate index (E(LT)) which was the lowest in treatment 6000 kg x hm(-2) of straw mulching. This study showed that straw mulching could increase the >0.25 mm aggregates and organic matter contents in 0-40 cm soil layer and improve the soil structural stability, and mulching with an amount of 6000 kg x hm(-2) had the best effect, being a reasonable straw mulching mode to be applied in the agricultural production in Weibei Loess Plateau.

Abstract
Calixaromatics have attracted much attention on molecular recognition owing to their flexible conformations, cavity structures, versatile recognition properties, and functions. However, conformational control of calixaromatics is still a challenging topic in the field of calixaromatics. Therefore, we explore the possibility to control the chirality of achiral calixaromatics, methylazacalix[6]pyridine (abbreviated as MACP6), by templating of DNA. We have found that MACP6 with opposite chirality can be achieved by controlling the secondary structure of bcl-2 2345 DNA. Furthermore, MACP6 with different chirality has been used to recognize fullerene derivatives in aqueous solution. Our results have provided a possible approach to construct chiral calixaromatics.

Abstract
A pair of primers with BamH I restriction site were designed to amplify the complete genome of goose circovirus. Two copies of the genome were ligated in tandem and cloned into pGEM-T Easy vector to construct an infectious clone named as pGEMT-2GoCV. The pGEMT-2GoCV linearized with EcoR I was transfected to negative embryos and gosling with Lipfectamine. PCR detection verified the proliferation of GoCV in geese. Some sera of the embryo transfected group were detected to be positive at 2 and 4 weeks after hatching and one bursa was detected to be positive at 4 weeks. Some sera of the gosling transfected group were also detected to be positive at 2 weeks after transfection. Furthermore, the mark in the PCR products were identified by BamH I digestion and the GoCV in positive tissue and sera were quantitated by Real-time PCR. The results showed that the virus load in positive bursa was 1.57 x 10(6) copies/mg, the virus load in positive sera were 3.52 x 10(4)-5.92 x 10(5) copies/microL. In conclusion, the infectious DNA clone constructed with two copies of full-length GoCV genome in tandem can transfect embryo and gosling and propagate the marked goose circovirus.

Abstract
By exposing Spodoptera litura Fabricius larvae to nickel (Ni) in artificial diets for successive three generations, we investigated the impacts of the dietary Ni on growth and immune response of the fifth and sixth instar larvae at 24 h intervals. The time of newly moulted fifth instar larvae was labelled as 0 h. After exposure to 5 mg/kg Ni for two generations, Ni exposure significantly improved larval phenoloxidase activity and encapsulation grade in fifth instar larvae when compared to controls, except for encapsulation grade at 72-120 h in the second generation. However, higher concentrations of Ni (≥10 mg/kg) only significantly reduced encapsulation grade at 72-120 h. In the third generation, insects given higher dietary levels of Ni (≥10 mg/kg) showed lower immune responses and retarded relative growth rate (RGR) compared to controls, but those exposed to lower Ni levels (≤5 mg/kg) had a significantly improved encapsulation grade at 24-72 h. Larvae at lower Ni level (≤5 mg/kg) treatments had significantly higher RGR in comparison with that in controls. There was no significant difference in food relative consumption rate (RCR) and RGR among any treatment of the fifth instar larvae in three successive generations. These results indicated that the type and extent of effects on growth and immune responses of S. litura varied with the Ni concentrations and exposure periods.

Abstract
The SNPs in partial coding sequence of MC3R and MC4R genes were identified by polymerase chain reaction followed by single strand conformation polymorphism (PCR-SSCP) analysis and DNA sequencing in shack-Kee and Columba domestica from Harbin area. Correlation analysis between MC3R and MC4R polymorphism and growth and body composition traits was carried by the least square analysis. The genotypes of T91G mutation in MC3R gene and A903G mutation in MC4R gene proved to have significant association with body weight, carcass weight, and holo-carcass weight in shack-Kee (P<0.05). The interaction of MC3R-T91G and MC4R-A903G was discussed through combination genotype analysis. The least square analysis showed that the combined genotype had significant association with holo-carcass weight (P<0.05). Multiple comparisons revealed that BBAA genotype birds had a higher holo-carcass weight than AABB genotype birds and BBAA genotype was the beneficial genotype for the growth of body weight.

Abstract
AIM: To identify the susceptible gene (s) for type 2 diabetes in the prevousely mapped region, 1p36.33-p36.23, in Han population of North China using single nucleotide polymorphisms (SNPs) and to analyze the haplotypes of the gene (s) related to type 2 diabetes.
METHODS: Twenty three SNPs located in 10 candidate genes in the mapped region were chosen from public SNP domains with bioinformatic methods, and the single base extension (SBE) method was used to genotype the loci for 192 sporadic type 2 diabetes patients and 172 normal individuals, all with Han ethical origin, to perform this case-control study. The haplotypes with significant difference in the gene (s) were further analyzed.
RESULTS: Among the 23 SNPs, 8 were found to be common in Chinese Han population. Allele frequency of one SNP, rs436045 in the protein kinase C/ζgene (PRKCZ) was statistically different between the case and control groups (P < 0.05). Furthermore, haplotypes at five SNP sites of PRKCZ gene were identified.
CONCLUSION: PRKCZ gene may be associated with type 2 diabetes in Han population in North China. The haplotypes at five SNP sites in this gene may be responsible for this association.

Abstract
OBJECTIVE To investigate the distribution of single nucleotide polymorphisms (SNPs) in CAPN10 gene in Chinese population and their relation with type 2 diabetes mellitus in Han people of Northern China. METHODS CAPN10 gene was sequenced to detect SNPs in different nationalities of China. Five SNPs were chosen to perform case-control study and haplotype analysis in 156 normal Han people of Northern China and 173 type 2 diabetes. One SNP was also analyzed with transmission-disequilibrium test (TDT) and sib transmission-disequilibrium test (STDT) in 68 type 2 diabetes pedigrees (377 people). RESULTS A total of 40 SNPs were identified in length of 8,936 bp, with an average of 1 in every 223 bp. The SNPs in CAPN10 gene did not distribute evenly and the SNPs in Chinese were different from those reported in Mexican American. There was no significantly statistical difference in the allele frequency of the 5 SNPs between case and control, and the haplotype frequencies in the two groups were not significantly different. No positive results was found in TDT and STDT analysis. CONCLUSIONS The SNP distribution of CAPN10 gene differs in different nationalities. The studied SNPs in CAPN10 gene may not be the major susceptibility ones of type 2 diabetes mellitus in Han people of Northern China.

Abstract
The present paper deals with an application of cluster analysis to the chemical identification of the drugs from fruits of Zingiberaceae. Thirty numerical characters were obtained from thin layer chromatograms of volatile oils and flavonoids. The coefficient of Seuclid was used to show quantitative index of similarities among the samples. By methods of systematic cluster, 4 dendrograms from each method were created respectively. The results show that the fruit drugs from Amomum are similar to each other, but different from those from Alpinia; the results from median method are in accordance with the classification of fruit drugs from Zingiberaceae by their traditional effects. This paper may be helpful in seeking new resources as well as in identifying the fruit drugs from Zingiberaceae.

Abstract
From May 1987 to January 1993, 233 patients with achalasia admitted to our hospital had been treated using a self-invented soft (fibrous) esophageal dilator, including 16 patients who failed in Heller's myotomy. 228 (97.85%) patients were dilated by way of mouth, 3 (1.29%) by way of stomach and 2 (0.86%) had had a transthoracic operation because of the rupture of the esophagus due to dilation. 19 (8.15%) came back to have the second dilation and 2 the third dilation. 73 (31.33%) cases were dilated in the out-patient department. In 97.85% of the patients, excellent and good results were obtained, through once, twice or thrice of dilation by way of mouth. No esophageal reflux or any sequela was seen after dilation.

Abstract
The cluster analysis shows that the phytochemical constituents in genera Ophiopogon and Liriope are obviously different from each other and even different species of the same genus are not quite similar. Being consistent with the result of the traditional morphological classification, the cluster analysis may provide a chemical evidence for the phytochemical taxonomy and identification of medicinal material Maidong.

Abstract
We report here the sialographic appearances of the submandibular gland in both primary and secondary Sjögren's syndrome (SS). In order to compare these with those of the parotid gland, we defined new criteria for the staging for SS based on the degree of depiction of the peripheral ducts. In 24 out of 74 cases the submandibular sialogram showed more advanced, destructive disease compared with the parotid. This study suggests that although SS involves the parotid gland first, it progresses in the submandibular gland more rapidly.
