Abstract
Objective: To analyze the ultrasonic features of tonsillar lymphoma to improve the diagnostic accuracy. Methods: The clinical, pathological and ultrasonic data of nine patients with tonsillar lymphoma confirmed by pathology at Tianjin Medical University Cancer Institute and Hospital during June 2015 and June 2022 were analyzed retrospectively, and the characteristics of their ultrasonic images were summarized. Results: All 9 cases of tonsil lymphoma were unilateral tonsil disease, including 4 cases on the left side and 5 cases on the right side. The average maximum diameter of tonsil lymphoma in 9 cases was 4.32 cm. There were 3 cases with simultaneous involvement of tonsil and cervical lymph nodes, all of which were ipsilateral lymph nodes. Gray scale ultrasound showed that the lesions were hypoechoic, with clear boundaries in 7 cases and unclear boundaries in 2 cases. The shape was full and irregular in 5 cases and oval in 4 cases. The echo was uniform in 7 cases and uneven in 2 cases. Color Doppler ultrasonography showed abundant internal blood flow signal in 1 case, a little dotted linear internal blood flow signal in 5 cases, and no obvious internal blood flow signal in 3 cases. Conclusions: The ultrasonic features of tonsillar lymphoma include hypoechoic area, clear boundary, full shape, irregular and uniform internal echo, no or low linear signal of internal blood flow. Ultrasonography is of great value in the diagnosis of this disease and can help clinical decision-making.

Abstract
PURPOSE Papillary thyroid carcinoma (PTC) represents the most common subtype of thyroid cancer (TC). This study was set out to explore the potential effect of CHD1L on PTC and type 2 diabetes mellitus (T2DM). METHODS We searched for T2DM susceptibility genes through the GWAS database and obtained T2DM-related differentially expressed gene from the GEO database. The expression and clinical data of TC and normal samples were collated from the TCGA database. Receiver operating characteristic (ROC) curve analysis was subsequently applied to assess the sensitivity and specificity of the CHD1L for the diagnosis of PTC. The MCP-counter package in R language was then utilized to generate immune cell score to evaluate the relationship between CHD1L expression and immune cells. Then, we performed functional enrichment analysis of co-expressed genes and DEGs to determine significantly enriched GO terms and KEGG to predict the potential functions of CHD1L in PTC samples and T2DM adipose tissue. RESULTS From two genes (ABCB9, CHD1L) were identified to be DEGs (p < 1 * 10-5) that exerted effects on survival (HR > 1, p < 0.05) in PTC and served as T2DM susceptibility genes. The gene expression matrix-based scoring of immunocytes suggested that PTC samples with high and low CHD1L expression presented with significant differences in the tumor microenvironment (TME). The enrichment analysis of CHD1L co-expressed genes and DEGs suggested that CHD1L was involved in multiple pathways to regulate the development of PTC. Among them, Kaposi sarcoma-associated herpesvirus infection, salmonella infection and TNF signaling pathways were highlighted as the three most relevant pathways. GSEA analysis, employed to analyze the genome dataset of PTC samples and T2DM adipose tissue presenting with high and low expression groups of CHD1L, suggests that these differential genes are related to chemokine signaling pathway, leukocyte transendothelial migration and TCELL receptor signaling pathway. CONCLUSION CHD1L may potentially serve as an early diagnostic biomarker for PTC, and a target of immunotherapy for PTC and T2DM.

Abstract
Grain size is one of the essential components determining rice yield and is a target for both domestication and artificial breeding. Gibberellins (GAs) are diterpenoid phytohormones that influence diverse aspects of plant growth and development. Several quantitative trait loci (QTLs) have been identified that control grain size through phytohormone regulation. However, little is known about the role of GAs in the control of grain size. Here we report the cloning and characterization of a QTL, GW6 (GRAIN WIDTH 6), which encodes a GA-regulated GAST family protein and positively regulates grain width and weight. GW6 is highly expressed in the young panicle and increases grain width by promoting cell expansion in the spikelet hull. Knockout of GW6 exhibits reduced grain size and weight, whereas overexpression of GW6 results in increased grain size and weight. GW6 is induced by GA and its knockout downregulates the expression of GA biosynthesis genes and decreases GA content in the young panicle. We found that a natural variation in the cis element CAAT-box in the promoter of GW6 is associated with its expression level and grain width and weight. Furthermore, introduction of GW6 to Oryza indica variety HJX74 can lead to a 10.44% increase in rice grain yield, indicating that GW6 has great potential to improve grain yield in rice.

Abstract
Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion: The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Abstract
BACKGROUND Leaf morphology and spikelet number are two important traits associated with grain yield. To understand how genes coordinating with sink and sources of cereal crops is important for grain yield improvement guidance. Although many researches focus on leaf morphology or grain number in rice, the regulating molecular mechanisms are still unclear. RESULTS In this study, we identified a prohibitin complex 2α subunit, NAL8, that contributes to multiple developmental process and is required for normal leaf width and spikelet number at the reproductive stage in rice. These results were consistent with the ubiquitous expression pattern of NAL8 gene. We used genetic complementation, CRISPR/Cas9 gene editing system, RNAi gene silenced system and overexpressing system to generate transgenic plants for confirming the fuctions of NAL8. Mutation of NAL8 causes a reduction in the number of plastoglobules and shrunken thylakoids in chloroplasts, resulting in reduced cell division. In addition, the auxin levels in nal8 mutants are higher than in TQ, while the cytokinin levels are lower than in TQ. Moreover, RNA-sequencing and proteomics analysis shows that NAL8 is involved in multiple hormone signaling pathways as well as photosynthesis in chloroplasts and respiration in mitochondria. CONCLUSIONS Our findings provide new insights into the way that NAL8 functions as a molecular chaperone in regulating plant leaf morphology and spikelet number through its effects on mitochondria and chloroplasts associated with cell division.

Abstract
As sessile organisms, plants have evolved numerous strategies to acclimate to changes in environmental temperature. However, the molecular basis of this acclimation remains largely unclear. In this study we identified a tRNAHis guanylyltransferase, AET1, which contributes to the modification of pre-tRNAHis and is required for normal growth under high-temperature conditions in rice. Interestingly, AET1 possibly interacts with both RACK1A and eIF3h in the endoplasmic reticulum. Notably, AET1 can directly bind to OsARF mRNAs including the uORFs of OsARF19 and OsARF23, indicating that AET1 is associated with translation regulation. Furthermore, polysome profiling assays suggest that the translational status remains unaffected in the aet1 mutant, but that the translational efficiency of OsARF19 and OsARF23 is reduced; moreover, OsARF23 protein levels are obviously decreased in the aet1 mutant under high temperature, implying that AET1 regulates auxin signaling in response to high temperature. Our findings provide new insights into the molecular mechanisms whereby AET1 regulates the environmental temperature response in rice by playing a dual role in tRNA modification and translational control.

Abstract
Objective: To compare the differences of risk factors and prognosis of pulmonary embolism (PE) between the Tibetans and the Hans. Methods: Patients over 18 years old with confirmed PE and complete clinical data from West China Hospital of Sichuan University from January 2010 to January 2016 were prospectively enrolled and divided into Tibetan group and Han group. Clinical data were collected to compare risk factors and short-term prognosis between Han group and Tibetan group. In addition, a 2-year follow-up was conducted among patients after discharge to investigate the long-term prognosis. Results: A total of 90 patients in Tibetan group and 626 patients in Han group were finally included in this study. Patients in Tibetan group were younger than Han group [(52.2±15.8) vs (59.8±16.6) years old, P<0.001], and the proportion of elderly patients (age ≥70 years) in Tibetan group was significantly lower than that of Han group (15.6% vs 33.7%, P=0.001). The hemoglobin, hematocrit, platelet counts and fibrinogen in Tibetan group were higher than those in Han group [(134.0±32.0) vs (122.2±25.7) g/L, (41.2±9.2)% vs (37.6±7.3)% and (222.2±97.5)×10(9)/L vs (187.5±87.2)×10(9)/L, 3.71(2.51, 4.89) vs 3.31(2.44, 4.42) g/L; P<0.001, <0.001 and P=0.001, 0.048, respectively]. Malignancy and chronic obstructive pulmonary disease were more common in Han group (P=0.011, 0.001), while prior venous thromboembolism history, pregnancy or a history delivery within 1 month were more common in Tibetan group (P=0.041, 0.001). Both short-term and long-term mortality in Tibetan group were significantly lower than that in Han group (2.2% vs 11.5%, 13.6% vs 24.9%; P=0.005, 0.020). Conclusions: Hypercoagulable state plays an important role in the pathogenesis of PE in Tibetan patients. Both short-term and long-term prognosis of PE in Tibetan patients are better than that in Han patients.

Abstract
Objective: To clarify the research status of economic burden of stomach cancer in China from 1996 to 2015. Methods: Based on three electronic literature databases (China Knowledge Resource Integrated Database, Wanfang Database and PubMed), a total of 2 873, 1 244 and 84 articles published during 1996 to 2015 were found, respectively, using keywords of"cancer","neoplasms","malignant tumor","tumor","economic burden","health expenditure","cost","cost of illness", and"China". According to the inclusion and exclusion criteria, 30 literatures were included in the final analysis. Then the basic information and study subjects, indicators and main results of economic burden were abstracted and analyzed. All the expenditure data were discounted to the values in 2013 by using China's percapita consumer price index. Results: Totally, 30 articles were included, covering 14 provinces and of which 16 were published during 2011-2015. One article was based on population-level and the remaining studies were all based on individual-level. The number of individual-level articles that reported direct medical, non-medical and indirectly economic burden was 29, 1 and 2, respectively. The main indicators of direct medical expenditure were expenditure per patient (22), per clinical visit (9) and per diem (11), respectively. The median expenditure per patient was 7 387-28 743 RMB (CNY), with average annual growth rate (AAGR) of 1.7% (1996-2013). The median expenditure per clinical visit was 18 504-41 871 RMB (2003-2013), with AAGR of 5.5%. The median expenditure per diem was 313-1 445 RMB (1996-2012), with AAGR of 3.7%. Difference was found among provinces. Conclusions: The evidence for economic burden of stomach cancer was still limited over the past two decades and mainly focused on individual and regional levels. An increase and differences in provinces were observed in direct medical expenditure. Evaluation on direct non-medical and indirect medical expenditure needs to be addressed.

Abstract
Grain number and size are interactive agronomic traits that determine grain yield. However, the molecular mechanisms responsible for coordinating the trade-off between these traits remain elusive. Here, we characterized the rice (Oryza sativa) grain size and number1 (gsn1) mutant, which has larger grains but sparser panicles than the wild type due to disordered localized cell differentiation and proliferation. GSN1 encodes the mitogen-activated protein kinase phosphatase OsMKP1, a dual-specificity phosphatase of unknown function. Reduced expression of GSN1 resulted in larger and fewer grains, whereas increased expression resulted in more grains but reduced grain size. GSN1 directly interacts with and inactivates the mitogen-activated protein kinase OsMPK6 via dephosphorylation. Consistent with this finding, the suppression of mitogen-activated protein kinase genes OsMPK6, OsMKK4, and OsMKKK10 separately resulted in denser panicles and smaller grains, which rescued the mutant gsn1 phenotypes. Therefore, OsMKKK10-OsMKK4-OsMPK6 participates in panicle morphogenesis and acts on a common pathway in rice. We confirmed that GSN1 is a negative regulator of the OsMKKK10-OsMKK4-OsMPK6 cascade that determines panicle architecture. The GSN1-MAPK module coordinates the trade-off between grain number and grain size by integrating localized cell differentiation and proliferation. These findings provide important insights into the developmental plasticity of the panicle and a potential means to improve crop yields.

Abstract
Objective: To explore the current status of research on economic burden of cancer in China from 1996 to 2014. Methods: The key words including cancer, economic burden, expenditure, cost were used to retrieve the literatures published in CNKI and Wanfang (the two most commonly used databases for literature in Chinese) and PubMed during 1996-2014. A total of 91 studies were included after several exclusionary procedures. Information on subjects and data source, methodology, main results were structurally abstracted. All the expenditure data were discounted to year of 2013 value using China's health care consumer price indices. Results: More than half of the included studies were published over the past 5 years, 32 of the studies were about lung cancer. Among the 83 individual-based surveys, 77 were hospital-based and obtained data via individually medical record abstraction, and most of which only considered the direct medical expenditure. Expenditure per cancer patient and expenditure per diem were the most commonly used outcome indicators. Majority of the findings on expenditure per cancer patient ranged from 10 thousands to 30 thousands Chinese Yuan (CNY), with larger disparity in lung and breast cancer (ranged from 10 thousands to 90 thousands CNY), narrower difference in esophageal and stomach cancer (ranged from 10 thousands to 50 thousands CNY), and most stable trend in cervical cancer (almost all the values less than 20 thousands CNY). Without exception, the expenditures per diem for all the common cancers were increasing over the period from 1996 to 2014 (3-7 fold increase). Only 8 population-level economic burden studies were included and the reported expenditure of cancer at national level ranged from 32.6 billions to 100.7 billions CNY. Conclusions: Evidence on economic burden of cancer in China from 1996 to 2014 are limited and weakly comparable, particularly at a population level, and the reported expenditure per patient may be underestimated.

Abstract
Objective: To explore existing evidence of economic burden of esophageal cancer in China over the past 20 years. Methods: Based on PubMed, CNKI and Wanfang, literatures published from 1996 to 2015 were retrieved with the key words such as " economic burden" , "cost of illness" and so on. Then the information excerpted from those literatures were analyzed after several exclusionary procedures for non-esophageal cancer related literatures. The information about subjects and data source, methodology, main results were structurally abstracted and then analyzed. Quality assessments were conducted independently by two investigators using an 11-item instrument recommended by the Agency for Healthcare Research and Quality (AHRQ) for cross-sectional studies. All the expenditure data were calculated according to year-specific personal health care consumer price index (CPI) of China, the annual growth rate was calculated according to the average speed of growth. Results: A total of 23 studies (21 individual surveys and 2 population-based surveys) were included in the analysis, in which 12 were published over the past 5 years. Among the 21 individual surveys, 17 were hospital-based and the data were obtained through medical record review, and most of which only considered the direct medical economic burden (including the average overall expenditure per patient, per time and per diem). The median expenditure per patient during 1996-2011 ranged from 7 463 to 37 647 yuan (RMB) and the average growth rate was 7.68%. The median medical expenditure per clinical visit during 1996-2013 ranged from 6 851 to 57 554 yuan (RMB) and the average growth rate was 11.89%. The median medical expenditure per diem during 1996-2010 ranged from 225 to 1 319 yuan (RMB) and the average growth rate was 12.53%. The direct medical expenditure per clinical visit varied greatly with area, which were much higher in Beijing, Shanxi and Hubei. In both individual survey and population-based survey, less data about the direct non-medical expenditure and the influence of indirect expenditure on the economic burden were reported. Conclusion: Less data are available on economic burden of esophageal cancer in China over the past 20 years and the data's comparability are poor, especially in terms of population level or indirect burden. Direct medical expenditure is on the rise, and regional differences.

Abstract
In mouse islet grafts under the kidney capsule, the potentiating responsiveness to acetylcholine was markedly attenuated after a few weeks. The question arose as to whether transplanted islets show an decreased responsiveness to potentiators in general. The effect of caffeine on glucose-induced insulin secretion was, therefore, examined. Intrastrain transplantation was performed in NMRI and BALB/c mice, and islet grafts were removed and perifused in vitro after 3 and 12 wk. In grafts from both NMRI and BALB/c mice, 16.7 mmol/L glucose induced a biphasic insulin release. When 1 or 5 mmol/L caffeine was included in the perifusion medium, there was a marked potentiation of the glucose-induced insulin release that was at least as responsiveness as fresh untransplanted islets. In the absence of caffeine, 3-wk-old BALB/c grafts reacted less strongly to acetylcholine than did untransplanted islets. The addition of 1 mmol/L caffeine did not enhance the potentiating effect of acetylcholine, whether in untransplanted or transplanted islets. Rather, the interaction between caffeine and acetylcholine appeared negative. We concluded that the glucose-induced insulin secretion exhibits a diminished potentiatory responsiveness to acetylcholine but not to caffeine. The displacement and denervation of transplanted islets is likely to affect either the cholinergic receptors or their mediated influence on intracellular calcium.

Abstract
OBJECTIVE To explore the risk factors of venous thromboembolism (VTE) recurrence and the predictive value of simplified pulmonary embolism severity index (sPESI) in medical inpatients. METHODS A total of 149 consecutive patients with first diagnosed VTE from the medical departments of West China Hospital of Sichuan University from January 2011 and December 2012 were enrolled and followed-up for 24 months. The VTE recurrence rate was calculated and univariate and multivariate cox proportional hazards regression analysis were performed to identify the risk factors associated with VTE recurrence. All the patients were evaluated by sPESI, and survival analysis was used to explore its value in predicting VTE recurrence in these medical patients. RESULTS Out of the included 149 patients, 23(15.4%) patients had VTE recurrence during the 2 years' follow-up and median recurrence time was 167 days. The univariate analysis showed bed rest, severe lung disease, nephrotic syndrome, inappropriate anticoagulant therapy, smoking, diabetes, and malignant neoplasm might be associated with VTE recurrence (P=0.043, 0.006, 0.009, 0.032, 0.098, 0.048, 0.021). Among these risk factors, the multivariate analysis revealed severe lung disease, nephrotic syndrome, and malignant neoplasm were the independent risk factors (HR=3.45, 5.67, 3.60; P=0.020, 0.020, 0.047); while for inappropriate anticoagulant therapy, the P value was marginal (HR=3.94, 95% CI: 0.99-15.63, P=0.051). The median sPESI scores of the patients with VTE recurrence was higher than that of the patients without VTE recurrence[1(1, 2) vs 0(0, 1), P=0.001], and patients with sPESI≥1 were associated with 5.57-fold increased risk of VTE recurrence compared with patients with sPESI=0 (95%CI: 1.79-17.30, P=0.001). Survival analysis also showed that the 2-year cumulative VTE recurrence rate of patients with sPESI≥1 was significant higher than that of patients with sPESI=0 (38.4% vs 5.7%, P=0.001). CONCLUSIONS The medical VTE patients have high VTE recurrence risk, and severe lung disease, nephrotic syndrome, malignant neoplasm and inappropriate anticoagulant therapy are important risk factors of VTE recurrence. The sPESI has predictive value for VTE recurrence in medical patients.

Abstract
Objective: To improve the awareness of bloodborne pathogen exposure protection knowledge, reduce the contact incidence (including sharp injuries, contacting with the broken skin and mucous mem-brane contact) , and increase the self-report incidence of bloodborne pathogen exposure in the healthcare work-ers of the investigated hospital after the intervention. To summarize effective prevention and intervention mea-sures of occupational exposure to bloodborne pathogen. Methods: The project was on the basis of previous inves-tigations in a general hospital, after comparing the personnel structure and departments distribution of 727 HC-Ws before the intervention and 614 HCWs after the intervention, we selected several departments in which the healthcare workers with a higher risk of occupational exposure to bloodborne pathogens. We promoted the hospi-tal to set up occupational health prevention and control system, improved related files, supplemented by knowl-edge training, discussion and field guidance, such a comprehensive intervention in the hospital. After the inter-vention, we conducted an cross-sectional investigation, and compared the rate of protection knowledge aware-ness, self-reporting rate after exposure, occupational exposure to bloodborne pathogens (including sharp inju-ries, contacting with the broken skin and mucous membrane contact) incidence before and after the intervention. Results: Before and after the intervention, the total score of the investigated population of 14 knowledge points that we focused on in training showed a significant difference (P<0.05) , total contact incidence of bloodborne pathogen exposure reduced from 81.57 persons/100 persons per year to 43.81 persons/100 persons per year, the RR of bloodborne pathogen exposure in the former investigation was 1.86 times of that in the latter investigation, the self-reported incidence increased form 2.06 persons/100persons per year to 9.45 persons/100 persons per year, self-reporting rate after exposure increased form 0.47% to 9.65%. Conclusion: The interventions signifi-cantly improved the awareness of bloodborne pathogen exposure protection knowledge, effectively reduced the contact incidence of bloodborne pathogen exposure, and increased the self-reported incidence in the healthcare workers of the investigated hospital.

Abstract
This study sought to investigate the correlations of V-raf murine sarcoma viral oncogene homolog B1 (BRAF) gene mutations with the clinicopathologic features of papillary thyroid carcinoma and central lymph node metastasis. We retrospectively analyzed the 2-year medical records of patients who underwent surgery for papillary thyroid carcinoma. After screening, the records of 126 patients who met the study requirements were used to assess the characteristics associated with the BRAF V600E gene mutation. The BRAF mutation incidence rate among patients with papillary thyroid carcinoma was 69.0% (87/126). Univariate analysis revealed that the BRAF mutation status was correlated significantly with both tumor size and lymph node metastasis (P < 0.05). Multivariate analysis revealed a significant correlation between lymph node metastasis and BRAF mutation status (P < 0.05). When the tumor diameter was ≤10 mm, the BRAF mutation status had no effect on lymph node metastasis (P > 0.05). When the tumor diameter was >10 mm, the incidence of lymph node metastasis was significantly higher among BRAF mutation-positive patients than among BRAF mutation-negative patients (P < 0.05). BRAF gene mutations independently predicted central lymph node metastasis in patients with papillary thyroid carcinoma. For patients preoperatively diagnosed to be BRAF mutation-positive, the importance of central lymph node dissection should be emphasized because the tumor diameter increases; regional lymphatic and adipose tissue dissection should be routinely conducted. However, in mutation-negative patients with tumor diameters of ≤5 mm, the need for central lymph node dissection should be re-examined.

Abstract
Biomass yield is one of the most important traits for wheat (Triticum aestivum L.)-breeding programs. Increasing the yield of the aerial parts of wheat varieties will be an integral component of future wheat improvement; however, little is known regarding the genetic control of aerial part yield. A doubled haploid population, comprising 168 lines derived from a cross between two winter wheat cultivars, 'Huapei 3' (HP3) and 'Yumai 57' (YM57), was investigated. Quantitative trait loci (QTL) for total biomass yield, grain yield, and straw yield were determined for additive effects and additive x additive epistatic interactions using the QTLNetwork 2.0 software based on the mixed-linear model. Thirteen QTL were determined to have significant additive effects for the three yield traits, of which six also exhibited epistatic effects. Eleven significant additive x additive interactions were detected, of which seven occurred between QTL showing epistatic effects only, two occurred between QTL showing epistatic effects and additive effects, and two occurred between QTL with additive effects. These QTL explained 1.20 to 10.87% of the total phenotypic variation. The QTL with an allele originating from YM57 on chromosome 4B and another QTL contributed by HP3 alleles on chromosome 4D were simultaneously detected on the same or adjacent chromosome intervals for the three traits in two environments. Most of the repeatedly detected QTL across environments were not significant (P > 0.05). These results have implications for selection strategies in wheat biomass yield and for increasing the yield of the aerial part of wheat.

Abstract
Mouse islets cultured for 1 or 4 days with or without 10 nM vasoactive intestinal polypeptide (VIP) were stained for tyrosine hydroxylase (TH) and examined for insulin secretion during culture and in a postculture perifusion system. Exposure to exogenous VIP for 4 days increased the frequency of islet cells expressing TH-like immunoreactivity. Regardless of the culturing conditions, the islets exhibited significant insulin secretory responses to 16.7 mM glucose, the effect being potentiated by 10 nM VIP in the perifusion medium. The insulin-releasing action of glucose and the potentiating effect of VIP were less pronounced in islets cultured for 1 day with VIP than in islets cultured without this neuropeptide. The following conclusions are suggested: (a) VIP stimulates the expression of TH in mouse islet cells; (b) the latency of the VIP-induced TH is a postreceptor phenomenon; (c) islet cultures exposed to VIP represent a new instance of the association between increased functional demands on beta cells and enhanced expression of TH and a new instance of VIP having trophic effects.

Abstract
Limitations in success of clinical islet transplantation may be coupled to a long-term decline in the secretory capacity of the grafted human islet tissue. To address this issue human or mouse islets were transplanted to the subcapsular space of the kidney of nude mice. After 4 or 12 weeks, the grafts were removed and tested for insulin secretory dynamics in a perifusion system. Insulin secretion of non-transplanted human islets was examined as well. Insulin extracted from 12-week human islet grafts was significantly lower than that from 4-week grafts. Quite in contrast, 12-week mouse islet grafts contained as much insulin as the 4-week grafts. When stimulated with high glucose, insulin secretion was increased by about 6-fold in non-transplanted human islets and 3-fold in 4-week-grafts. The 12-week-grafts were just marginally stimulated by the high glucose stimulation. The mouse islets maintained a 2- to 3-fold insulin response at both time points when challenged high glucose. In non-transplanted human islets glucose-induced insulin secretion was inhibited by noradrenaline, while there was no such effect in the human islet grafts. Addition of acetylcholine potentiated glucose-induced insulin secretion 1-4 fold in both non-transplanted and grafted human islets. When human islet grafts were stimulated by both glucose and caffeine or arginine, insulin secretion was increased severalfold in comparison to glucose stimulation alone. The present results indicate that human islets, in contrast to mouse islets, progressively diminish their insulin content, as well as the capacity to secrete insulin in response to glucose after transplantation into nude mice. Moreover, grafted human islets also lose their responsiveness to the neurotransmittor noradrenaline. These findings may partly explain why clinical islet transplantation so far has met with limited success.

Abstract
In mouse islet grafts under the kidney capsule, the potentiating responsiveness to acetylcholine was markedly attenuated after a few weeks. The question arose as to whether transplanted islets show an decreased responsiveness to potentiators in general. The effect of caffeine on glucose-induced insulin secretion was, therefore, examined. Intrastrain transplantation was performed in NMRI and BALB/c mice, and islet grafts were removed and perifused in vitro after 3 and 12 wk. In grafts from both NMRI and BALB/c mice, 16.7 nmol/L glucose induced a biphasic insulin release. When 1 or 5 mmol/L caffeine was included in the perifusion medium, there was a marked potentiation of the glucose-induced insulin release that was at least as responsiveness as fresh untransplanted islets. In the absence of caffeine, 3-wk-old BALB/c grafts reacted less strongly to acetylcholine than did untransplanted islets. The addition of 1 mmol/L caffeine did not enhance the potentiating effect of acetylcholine, whether in untransplanted or transplanted islets. Rather, the interaction between caffeine and acetylcholine appeared negative. We concluded that the glucose-induced insulin secretion exhibits a diminished potentiatory responsiveness to acetylcholine but not to caffeine. The displacement and denervation of transplanted islets is likely to affect either the cholinergic receptors or their mediated influence on intracellular calcium.

Abstract
To elucidate the adrenergic responsiveness of transplanted pancreatic islets, normal BALB/c mice received 150 syngeneic islets under the left kidney capsule. After 12-40 weeks, the grafts were removed and compared with untransplanted islets by an in vitro perifusion technique. Noradrenaline (NA), 3 mumol/l, completely inhibited glucose-stimulated insulin release from untransplanted islets but not from grafts, whether or not the beta adrenergic blocker, L-propranolol, was present. UK-14,304, an alpha 2-specific adrenergic agonist, inhibited glucose-induced insulin secretion from untransplanted islets by 80-92% at 0.1 or 1 mumol/l, and by 35-56% at 5-10 nmol/l. Insulin secretion from islet grafts was also markedly inhibited by 0.1 or 1 mumol/l, but not by 5 or 10 nmol/l, UK-14,304. It is suggested that the diminished adrenergic inhibition of insulin release from islet grafts reflects an altered function of the alpha 2 adrenoceptors on the beta-cells.

Abstract
Mouse pancreatic islet grafts under the kidney capsule of syngeneic hosts were removed and perifused in vitro 1-40 weeks after the transplantation. In comparison with fresh islets, 12- to 40-week-old grafts exhibited an attenuated first phase of glucose-stimulated insulin release. In grafts 1, 12, 28, or 40 weeks old, but not in fresh islets, the mean secretory rate during the initial 10 min of stimulation was significantly lower than that during the subsequent 15 min. When expressed in relation to insulin content, the insulin output in response to 11 mmol/L glucose was no less from grafts than from fresh islets; in grafts 12 or 40 weeks old at 16.7 mmol/L glucose, the fractional output above baseline was significantly diminished during the initial 10 min, but not subsequently. Immediately on switching from basal to stimulatory glucose concentration, there was a transient drop in insulin secretion from the grafts, especially after more than 12 weeks of transplantation and in response to 16.7, as compared with 11, mmol/L glucose. When glucose was switched back from stimulatory to basal concentration, grafts also frequently exhibited a transient increase in the insulin secretory rate. Neither initial drops nor "off responses" were seen in untransplanted islets. The modifications of the secretory dynamics in islet grafts suggest that transplantation influences the balance between the stimulatory and inhibitory influences of glucose on the beta-cell's secretory machinery.

Abstract
Insulin release is inhibited by adrenergic alpha-2 agonism in normal beta-cells. To test whether the inhibitory response to noradrenaline is modified by transplantation, we studied insulin release from freshly isolated islets and from syngeneic islets transplanted under the kidney capsule of non-diabetic C57BL/6 mice. When perifused in vitro, fresh islets, as well as grafts harvested 1 or 3 weeks after transplantation, reacted to 2.5 mumol/l noradrenaline with a complete inhibition of insulin release induced by 16.7 mmol/l D-glucose. In contrast, islet grafts harvested after 6, 12, or 21 weeks exhibited a conspicuous insulin secretory response to 16.7 mmol/l glucose in the presence of 2.5 mumol/l noradrenaline. Also a concentration of 0.25 mumol/l, noradrenaline inhibited the glucose-induced insulin release from fresh islets but not from 6-week-old islet grafts. It is concluded that transplantation under the kidney capsule induces a decreased inhibitory responsiveness to noradrenaline in islet grafts.

Abstract
Pancreatic islets from BALB/c mice were transplanted to the kidney of syngenic hosts. After 1-40 weeks, the grafts were removed, perifused in vitro, and extracted. Fresh islets were similarly examined. The graft insulin content fell by 70% in 1 week and remained low throughout the observation period. In contrast, rates of basal or glucose-stimulated insulin release were not much, if at all, decreased. In fresh islets and grafts removed after 3 or 28 weeks, 2 consecutive pulses of glucose stimulation, 20-25 min long and separated by 20 min at basal glucose concentration (2 or 2.8 mmol/L), elicited the same insulin secretory response. When 10 mumol/L acetylcholine and 10 mumol/L eserine were present during the second pulse, the glucose-stimulated insulin release from fresh islets was potentiated as much as 11-fold. This potentiation was reduced by one half during the first week of transplantation, and subsequently by 80-90%. It is concluded that vagal deprivation rapidly induces a state of persistent cholinergic refractoriness in transplanted beta-cells, despite morphological signs of autonomic reinnervation of the grafts.

Abstract
To test whether the transplantation of pancreatic islets affects their basic functions, collagenase-isolated mouse islets were inserted under the left renal capsule of recipient animals. After various periods of time, grafts were removed from the kidney and examined for insulin content and secretory dynamics in a perifusion system. During syngeneic (C57BL/6, BALB/c) or subsyngeneic (NMRI) intrastrain transplantation, the graft insulin content fell drastically during the first week and stayed low for at least 6 weeks; first-phase secretion in general appeared suppressed. Immunosuppression by cyclosporin A had little effect on (sub)syngeneic grafts but markedly improved the performance of allotransplants. Daily injections of the calcium antagonist, verapamil, enhanced the insulin secretory responses of isolated grafts, whether (sub)syngeneic or allogeneic. In syngeneic and subsyngeneic grafts, the potentiating effect of acetylcholine on glucose-induced insulin release was markedly diminished, whereas that of caffeine was not. Transplanted islets also exhibited a subnormal responsiveness to the inhibiting action of noradrenaline. It is concluded that chronic denervation and transplantation of pancreatic islets may cause fundamental changes in the beta-cell responses to physiological regulators of insulin release.

Abstract
Islets from normal NMRI mice were transplanted under the kidney capsule of syngeneic recipients. The graft-bearing mice were divided into 4 groups treated daily with cremophor alone (control), cyclosporine (25 mg/kg body wt), CsA in combination with the calcium antagonist verapamil (0.4 mg/kg), or verapamil alone. After 3 weeks the grafts were removed, analyzed for insulin secretory dynamics in a perifusion system, and extracted for their contents of insulin. The graft insulin content was significantly decreased by CsA, an effect counteracted by verapamil. As compared with controls, all treatments increased the basal insulin at 2.8 mmol/L glucose. CsA together with verapamil enhanced the biphasic secretory response to 16.7 mmol/L glucose, whether expressed per graft or per unit of insulin content. The glucose-stimulated insulin release per graft was greater after combining CsA with verapamil than after CsA alone. It is concluded that CsA has adverse effects on islets transplanted to the kidney, and that these effects can be ameliorated by combining the immunosuppressant with verapamil.

Abstract
Treatment of NMRI mice with cyclosporin A (25 mg/kg body wt) for 11 days caused a marked fall in pancreas insulin content, although plasma glucose and plasma insulin were unchanged. When islets from untreated mice were exposed to cyclosporin A (2 mg/l) in vitro, no effect was seen in the first hour. After 24 h, cyclosporin A had significantly decreased the islet content of insulin. Post-culture microperifusion showed that cyclosporin A for 24 or 72 h inhibited the insulin secretory responsiveness. Verapamil in vivo (0.4 mg/kg body wt per day) or in vitro (37.5 micrograms/l) did not modify these effects. Verapamil at 25 mg/l suppressed the release of insulin but afforded no obvious protection against cyclosporin A during culture. The beneficial action of verapamil on islets transplanted to the kidney may reflect renal events rather than a primary interaction of drugs in the islets.
