Abstract
Objective: To investigate the relationship between serum lysophosphatidylcholine (LPC) level and the health index of the elderly. Methods: A total of 251 subjects were selected from the 2016 baseline survey of the Yongfu Longevity Cohort in Guangxi Province among whom 66, 63 and 122 were in the young and middle-aged group (≤59 years old), the young group (60-89 years old) and the longevity group (≥90 years old), respectively. Demographic data were collected and related indicators of height, weight, blood pressure and lipid metabolism were measured. The cognitive and physical functions of the elderly were assessed by the results of the simple mental state scale and the daily living activity scale to construct the health index of the elderly. The serum levels of LPC16∶0, LPC18∶0, LPC18∶1 and LPC18∶2 were determined by liquid chromatography-tandem mass spectrometry, and the differences among different ages and health status groups were compared. The logistic regression model was used to analyze the relationship between the serum LPC level and the health index of the elderly. Results: With the increase in age, the proportion of female subjects increased, and the rate of smoking and drinking decreased. BMI, TC, TG, LDL-C, diastolic blood pressure, and the four LPCs levels decreased with the increase of age, and systolic blood pressure levels increased with the increase of age (all P values<0.05). There was no significant difference in HDL-C levels among age groups (P>0.05). With the decline of health status in the elderly, serum levels of LPC16∶0, LPC18∶0, LPC18∶1 and LPC18∶2 showed a downward trend (all P values<0.001). After adjusting for age and gender, only LPC18∶0 was associated with the health status in old age [OR (95%CI): 0.48 (0.25-0.92)]. For every 1 standard deviation (16.87 nmol/L) increase in serum LPC18∶0 concentration, the risk of poor health status in old age decreased by 52%. Conclusion: Serum LPC18∶0 was associated with the health status in old age independent of age and sex.

Abstract
International research on healthy life expectancy (HALE) focuses on inequality of socioeconomic status and individual natural attributes. With the acceleration of population ageing and the increase in average life expectancy, the extension of unhealthy life expectancy and the increase of social and economic burden caused by diseases have gradually attracted the attention of countries around the world. Therefore, the evaluation of disease factors affecting HALE is a meaningful direction in the future. This study introduces the development process and commonly used measurement methods of HALE. According to the definition of health from the Global Burden of Disease Study and World Health Organization, physical and mental diseases such as cardiovascular and cerebrovascular diseases, chronic respiratory diseases, diabetes, malignant tumors and depression were selected to summarize the impact of these diseases and pre-disease states on HALE. It is expected to provide a theoretical basis for the formulation of relevant public health policies and the improvement of quality of life in China.

Abstract
The reconstruction of tactile function during the repair of skin damage caused by factors including burns is inseparable from the functional regeneration of tactile receptor Merkel cells. Merkel cells mainly exist in the basal layer of the epidermis and are closely connected with nerves to form Merkel cell-nerve complexes, which play an important role in biological organisms. A large number of studies have shown that Merkel cells conduct precise transmission of mechanical force stimuli through the mechanically gated ion channels PIEZO2, and perform the function of tactile receptors. In this paper, we discussed the characteristics of Merkel cells and analyzed the different subgroups that may possibly exist in this type of cells and their functions, at the same time, we investigated the animal model research of touch-related diseases and the clinical diseases related to touch, revealing the importance of Merkel cell function research.

Abstract
Objective: To investigate the feasibility of assessing cognitive function of the elderly by serum metabolites of brain-gut axis. Methods: Convenience sampling was used to select 100 and 60 participants from the healthy population cohort and microecological balance cohort of the longevity population in Guangxi, to constitute subset of healthy population and longevity population, respectively. A questionnaire was used to investigate the demographic characteristics of the subjects, 2-5 ml of fasting venous blood was collected from the subjects, and the serum untargeted metabolomics was determined by liquid chromatography tandem mass spectrometry. The biomarkers related to the brain-gut axis were collected through literature retrieval, and the results were intersected with the untargeted metabolites and annotated. Spearman correlation analysis was used to screen serum metabolites of brain-gut axis associated with aging, and multiple linear regression method was used to construct biological age model. The mini mental status examination was used to evaluate the cognitive function of longevity population subsets. The differences of biological age and chronological age of longevity population subsets with different cognitive function were compared. Results: The M (Q1, Q3) of subset of healthy population and longevity population were 64 (38, 72) and 97 (95, 99) years old, respectively, and there were 50 (50.0%) and 44 (73.3%) females, respectively. Nine serum metabolites of brain-gut axis were obtained by initial screening, which were propionic acid, glutamic acid, γ-aminobutyric acid (GABA), lactic acid, 5-hydroxytryptamine (5-HT), tryptophan, trimethylamine oxide, dopamine and canine urea. Spearman correlation analysis showed that glutamic acid and dopamine were positively correlated with aging (r values were 0.208 and 0.524, respectively, all P values<0.05), and tryptophan, 5-HT and GABA were negatively correlated with aging (r values were -0.308, -0.533 and -0.213, respectively, all P values<0.05). The biological age model was constructed as: y=49.81-1.18×10-5× GABA-1.82×10-4×5-HT+1.99×10-3×dopamine+1.65×10-6×glutamic acid -2.04×10-6×tryptophan+2.36×gender, where y was the biological age (years), the items on the right were the intercept item, the relative concentration of each metabolite, and gender (male=1, female=2). The coefficient of determination of model was 0.50 (P<0.001). The M (Q1, Q3) of the chronological age of the subset of longevity population with poor, moderate and good cognitive function were 97 (94, 100), 97 (93, 101) and 96 (94, 101) years old, respectively, and there was no statistical significance in pairwise comparison (all P values>0.05). The M (Q1, Q3) of the biological age of the subjects with better cognitive function was 51 (38, 54) years old, which was lower than that of the subjects with poor cognitive function [57 (47, 61)] (P=0.040). Conclusion: The biological age model can be constructed based on serum metabolites of brain-gut axis and used to evaluate the cognitive function of the elderly.

Abstract
Objective: To construct an epigenetic clock model for assessing and calibrating human biological age. Methods: Convenience sampling was used to select 186 subjects from the longevity cohort of Guangxi Zhuang Antonornous Region from July 1 to November 30, 2019, and 124 subjects from the physical examination population of the Seventh Medical Center of the PLA General Hospital from October 1 to December 31, 2020. Self-designed questionnaire was applied to collect demographic characteristics and family history of disease. Physical examination was applied to determine heart rate and blood pressure. Fasting peripheral venous blood was drawn for determination of fasting plasma glucose, plasma total cholesterol, triglyceride, plasma high-density lipoprotein cholesterol, plasma low-density lipoprotein cholesterol and telomere length. Methylation levels of EDARADD cg09809672, IPO8 cg19722847, NHLRC1 cg22736354, P2RX6 cg05442902 and SCGN cg06493994 were detected by targeted methylation site sequencing. A total of 54 subjects with unqualified quality control of DNA methylation and telomere length were excluded, and 256 subjects' data were finally analyzed. Trend test was used for the change of methylation level among different ages groups, multiple linear regression method was used to build prediction models of biological age. Kendal rank correlation analysis was used to evaluate the correlation of age gap (Gregorian calendar age minus biological age) with telomere length. Independent sample t-test was used to compare the health-related indicators between subjects with different age gap within different age groups. Results: The M(Q1, Q3)of age of subjects were 67 (51, 91) years old, including 166 females (64.84%). With increase of age, the methylation levels of gene loci were decreased (EDARADD cg09809672, IPO8 cg19722847 and P2RX6 cg05442902) and increased (NHLRC1 cg22736354 and SCGN cg06493994) (all P values<0.05). The established biological age prediction model was as follows: Y=-53.121×EDARADD cg09809672-137.564×IPO8 cg19722847+141.040×NHLRC1 cg22736354-67.893×P2RX6 cg05442902+149.547×SCGNcg06493994+4.592×sex+64.185 (R2=0.86, P<0.001), where Y was the biological age, and the items in the equation were methylation level, sex (male =1, female =2) and intercept in sequence. The Kendall rank correlation coefficient between age gap and telomere length was 0.731 (P<0.001). Compared with the subjects whose age gaP<0, the subjects with age gaP≥0 had higher systolic blood pressure in adolescence [(88.50±8.89) and (109.83±9.48) mmHg, respectively, 1 mmHg=0.133 kPa]; lower TC [(5.48±0.23) and (3.98±0.54) mmol/L, respectively, ] and TG [(3.51±0.32) and (3.41±0.20) mmol/L] in young adults; lower fasting blood glucose in middle age [(6.17±0.67) and (5.37±0.79) mmol/L, respectively, ] and higher diastolic blood pressure in nonagenarian age [(76.99±6.78) and (83.97±9.36) mmHg, respectively, ] (all P values<0.05). Conclusion: The constructed epigenetic clock model can be used to evaluate and calibrate human biological age.

Abstract
Glaucoma is the world's leading cause of irreversible blindness. As a chronic disease, it requires lifelong follow-up and management. In the long-term follow-up of glaucoma patients, a diagnosis and treatment management system is helpful. Despite the availability of various means of informationalized record management, there remain problems and challenges, like a lack of unified file management standards, data incompatibility, and barriers to inter-hospital data sharing, which lead to the failure to establish a comprehensive and standardized glaucoma record for patients. It is necessary to form a standardized management system so as to improve the efficiency and accuracy of the diagnosis and treatment of glaucoma, better maintain the visual function of patients and reduce the burden on society and family.

Abstract
Glaucoma is a serious irreversible blinding disease. The pathogenesis is still unknown, and the diagnosis and treatment effect is not good. An effective early diagnosis method is urgently needed. In recent years, a number of glaucoma-related biomarkers have been discovered. In order to promote clinical application of these biomarkers, a series of studies are actively carried out to clarify specificity and sensitivity of these molecules, to verify the criteria by clinical randomized controlled trials, and to provide large sample data by multi-center clinical trials. However, the samples of these biomarkers are provided by patients who have been diagnosed with glaucoma by clinical examinations. The differences may represent the molecular features of middle-stage and advanced glaucoma. Whether they are helpful for early diagnosis and the exploration of pathological mechanisms should be further investigated. This article describes the potential molecular targets that can help in diagnosis of glaucoma from the aspects of DNA, RNA and protein, and discusses further research pathways and clinical application prospects. It is hoped to explore the effective molecular marker for early diagnosis of glaucoma. (Chin J Ophthalmol, 2021, 57: 707-711).

Abstract
Objective: To explore the epidemiologic characteristics of long-lived population and influencing factors in Shanglin county of Guangxi and provide scientific basis for the study of health and longevity in Guangxi. Methods: We collected and analyzed the general demographic cross-sectional data of the long-lived individuals (≥90 years old) in 11 villages and towns by multi-source registration and face-to-face interview. The age group control design was adopted to conduct a comparison among the longevity group (90-100 years old), centenarian group (≥100 years old), the longevity plus centenarian group and control group (local population aged 40-85 years), and identify the factors related to longevity. Results: Among the 496 007 people registered in Shanglin, 1 533 were aged ≥90 years, including 1 453 in the longevity group, with an average age of (92.84±2.46) years, and 80 in the centenarian group, with an average age of (102.67±2.60) years. The spatial distribution of long-lived individuals and centenarians was mainly in the north and central areas, and sparse in southwest area. Analysis on factors related to health and longevity indicated that old people with Zhuang ethnic (OR=1.551,95%CI:1.308-1.838), married (OR=55.507,95%CI:36.087-85.377) and moderately high waist-to-hip ratio (OR=258.056,95%CI:27.775-2 397.569), and SBP (OR=1.019,95%CI:1.013-1.026) tended to live longer. Conclusions: We found that the rate of longevity in Shanglin was higher than the average level in Guangxi and China. Longevity in Shanglin country had unique spatial and population distribution characterics of female longevity more than male longevity, mainly Zhuang ethnic and so on. Being women, married, family history of longevity, appropriate high waist-to-hip ratio, SBP and blood sugar level might be positive factors for longevity in Shanglin, but the impacts of other factors on longevity need further study.

Abstract
Objective: To investigate the epidemiological characteristics and relevant factors among individuals characterized by their longevity in multiple regions of Guangxi Zhuang Autonomous Region, and provide a valuable scientific perspective for the research in health and longevity of the elderly in Guangxi. Methods: Registration and face-to-face questionnaire on a door-to-door basis were adopted to collect the demographic characteristics of the long-lived individuals (≥90 years old) in Bama of Hechi city, Yongfu of Guilin city, Dongxing of Fangchenggang city, Guangxi. Then, among the local general population, individuals within the age group between 40 and 85 years old were selected randomly as controls. Correlations were then analyzed between the relative health and longevity of the subjects and their gender, ethnicity, family history, disease history, marital status, the number of family generations, the number of children, smoking, drinking, outdoor activities, sleep and other health-related factors, then the result was subject to further analysis by comparing the long-lived population and the control population respectively. Results: Among 691 500 of the permanent residents of Bama, Yongfu and Dongxing city, 1 005 cases were 90 years old and over with a ratio of 145.34 out of 100 000 persons; within the 1 005 cases, 944 were aged between 90 and 100 (longevity rate: 136.51/100 000) with an average age of (93.28±2.57); 61 cases were aged 100 or over, arriving at a centenarian rate of 8.82/100 000 with an average age of (102.00±3.05) years. Significant differences were found just among three particular factors - regional distribution (P=0.014), history of disease (P=0.002), four generations of family (P=0.008) between nonagenarians and centenarians (P<0.05), while the other 15 indicators did not show anything noteworthy. The result indicated that longevity and centenarians might be the same group and then we combined both groups into one. By cross-comparison between the longevity-plus- centenarians and the control group in the region, factors listed below exhibited significant correlation with health and longevity: marital status (OR=26.469, 95%CI: 13.208-53.045), number of generations within the family (OR=5.419, 95%CI: 3.418-8.592), number of male offspring (OR=2.013, 95%CI: 1.555-2.607), number of female offspring (OR=1.380, 95%CI: 1.122-1.696), and the frequency of outdoor activities (OR=10.226, 95%CI: 3.164-33.045). Conclusions: The longevity rate is higher in the general natural population in Bama, Yongfu and Dongxing of Guangxi. The phenomenon may owe to favorable family structure, atmosphere within or out of the family or other elements related with social surrounding. Among them all, mentality, inclination to physical exercise and regular rhythm of life may all exert tremendous contributory influence here.

Abstract
Objective: To analyze the clinical characteristics of early organ injury in elderly patients with severe burns and the effects on the prognosis of patients. Methods: From January 2010 to August 2018, 62 patients with severe burns (43 men and 19 women, aged from 60 to 89 years at the time of admission) who were hospitalized in the Institute of Burn Research of the First Affiliated Hospital of Army Medical University (the Third Military Medical University, hereinafter referred to as the author's affiliation), meeting the inclusion criteria, were included in elderly (E) group, and 124 patients with severe burns (86 men and 38 women, aged from 18 to 59 years at the time of admission) at the same term were included in young and middle-aged (YM) group. Treatment of patients in the 2 groups followed the conventional procedures of the author's affiliation. The following data of patients in the 2 groups were retrospectively analyzed. (1) Fluid replacement volume and urine volume within the first and second post injury hour (PIH) 24 were recorded. The levels of hemoglobin, haematocrit, and blood lactic acid at admission, PIH 24 and 48 were recorded. (2) The creatine kinase isozyme-MB (CK-MB), total bilirubin, blood creatinine, oxygenation index, and blood platelet count at admission, at shock stage, and on post injury day (PID) 3 to 7 were collected. (3) The days of seriously or critically ill and deaths were recorded. Data were processed with chi-square test, group t test, Mann-Whitney U test, analysis of variance for repeated measurement, and Bonferroni correction. Results: (1) There were no statistically significant differences in fluid replacement volume within the first and second PIH 24, and urine volume within the second PIH 24 between patients in the 2 groups (t=0.351, 1.307, 1.110, P>0.05). The urine volume of patients in group E within the first PIH 24 was significantly less than that in group YM (t=5.628, P<0.05). There were no statistically significant differences in levels of hemoglobin (t=0.011, 1.075, 0.239), haematocrit (t=0, 0.033, 0.199), and blood lactic acid (t=0.017, 1.002, 0.739) at admission, PIH 24 and 48 between patients in the 2 groups (P>0.05). (2) There were no statistically significant differences in levels of CK-MB at admission and on PID 3 to 7 between patients in the 2 groups (t=0.069, 0.001, P>0.05). The level of CK-MB of patients in group E at shock stage was significantly higher than that in group YM (t=4.017, P<0.05). There were no statistically significant differences in levels of total bilirubin at admission and on PID 3 to 7 between patients in the 2 groups (t=0.227, 0.002, P>0.05). However, the level of total bilirubin of patients in group E at shock stage was significantly higher than that in group YM (t=6.485, P<0.05). The levels of blood creatinine of patients in group E at admission and shock stage were significantly higher than those in group YM (t=4.226, 12.299, P<0.05 or P<0.01), while there was no statistically significant difference between them on PID 3 to 7 (t=0.693, P>0.05). The oxygenation indexes of patients in group E at admission and shock stage and on PID 3 to 7 [(371±16), (263±16), and (228±18) mmHg (1 mmHg=0.133 kPa)] were lower than (420±13), (327±13), and (281±17) mmHg of patients in group YM, respectively (t=5.650, 9.782, 4.856, P<0.05 or P<0.01). There were no statistically significant differences in levels of blood platelet count at admission and shock stage between patients in the 2 groups (t=0.038, 0.588, P>0.05), while the level of blood platelet count of patients in group E on PID 3 to 7 was significantly lower than that in group YM (t=6.636, P<0.05). (3) The days of seriously or critically ill and death rate of patients in group E were respectively longer or higher than those in group YM (Z=-2.303, χ(2)=13.676, P<0.05 or P<0.01). Conclusions: In the case of the same tissue perfusion at shock stage, injuries in heart, liver, kidney, lung, and coagulation system in elderly patients with severe burns are more obvious than those in young and middle-aged patients, with more severe illness and higher mortality.

Abstract
Intraocular pressure is the most important and most easily controlled clinical parameters of glaucoma. It has a fluctuation and circadian rhythm. The 24 hours intraocular pressure measurement can better reflect the changes of intraocular pressure. It is clear that peak IOP is an independent risk factor for the progression of glaucoma, but the effect of IOP on glaucoma progression is worth exploring. This article focuses on whether IOP fluctuation is an independent risk factor for glaucoma progression, how to obtain the 24-hour intraocular pressure curve, the future direction of 24-hour intraocular pressure monitoring and other issues in order to cause clinical concern.

Abstract
BACKGROUND The best therapy to prevent esophageal variceal (EV) rebleeding in cirrhotic patients who are non-responsive to pharmacological therapy have not been determined. AIMS To evaluate efficacy of a strategy to assign different treatments according to hepatic vein pressure gradient (HVPG) values to prevent EV rebleeding in non-responders. METHODS This study is a non-randomized controlled prospective study. 109 cirrhotic patients with EV bleeding who were non-responders based on two HVPG measurements were enrolled and divided two groups: 55 patients (EVL+β-blocker group) were treated with endoscopic variceal ligation (EVL) and nonselective β-blocker; 54 patients (HVPG-guided group) were treated with EVL and nonselective β-blocker if HVPG ≤ 16 mmHg (low-HVPG), with percutaneous transhepatic variceal embolization (PTVE) if HVPG > 16 mmHg and ≤ 20 mmHg (medium-HVPG), or with transjugular intrahepatic portosystemic shunt (TIPS) if HVPG > 20 mmHg (high-HVPG). Patients were followed up for rebleeding and mortality. RESULTS The mean follow-up period was 17.0 months; rebleeding was higher in the EVL+β-blocker group than HVPG-guided group (25.5%, 9.3%, P = 0.026); 3-year probability of rebleeding in the EVL+Beta-blocker group increased with elevated levels of HVPG (12.5% vs 46.4% vs 64.9%, χ(2) = 11.551, P = 0.003), and 3-year probability of survival was no difference (96.6% vs 85.7% vs 90.9%, χ(2) = 2.638, P = 0.267). Rebleeding rate in PTVE group (7.7%) was lower than that in EVL+β-blockergroup with medium-HVPG (35.7%), but there was no difference. Rebleeding rate in TIPS group (7.7%) was lower than that in EVL+β-blockergroup with high-HVPG (45.5%), but there was no difference. CONCLUSIONS HVPG measurement was useful for making decisions to select EVL and Beta-blocker, PTVE or TIPS in secondary prophylaxis. HVPG-guided treatment is feasible and effective in preventing esophageal varices rebleeding.

Abstract
AIM Functional dyspepsia (FD) is a clinical syndrome with chronic gastroduodenal symptoms without noticeable organic or systemic diseases. According to the Rome III consensus, FD can be subdivided into PDS (postprandial distress syndrome) and EPS (epigastric pain syndrome). Neurotransmitters are involved in the development and pathology of FD. However, the expression profiles of neurotransmitters in FD patients are not clear. This study aimed to investigate the expression profile of neurotransmitters in the duodenal mucosa of FD patients. METHODS A total of 48 FD patients treated at our hospital were included in this study: 23 patients with PDS and 25 patients with EPS. Another 21 healthy volunteers served as normal controls. The duodenal mucosa was biopsied with gastroscopy and examined with immunohistochemical staining against serotonin, substance P, inducible nitric oxide synthase (iNOS), and vasoactive intestinal peptide (VIP). Mast cells were identified with toluidine blue staining. RESULTS The duodenal iNOS levels were significantly higher in PDS patients than the normal controls (P<0.05). The expression of serotonin, substance P, and VIP did not differ significantly among the groups. Mast cell counts and the percentage of mast cells with degranulation were significantly higher in PDS and EPS patients than normal controls (P<0.001) In addition, iNOS expression levels were positively correlated with percentage of degranulating mast cells (r=0.321, P=0.008). CONCLUSIONS In conclusion, duodenal iNOS may be involved in the pathogenesis of PDS.

Abstract
An increase in interleukin (IL)-17A-producing cells, particularly at sites of tissue inflammation, is observed frequently, yet the mechanism is not fully understood. This study aims to dissect the role of IL-17 in autoimmunity-mediated neuroinflammation. The cytokine milieu containing elevated IL-17, which often appears in active states of autoimmunity, was mimicked in vitro by a supernatant obtained from rat peripheral blood monocytes stimulated with phorbol mystistate acetate (PMA)/ionomycin. The application of such inflammatory media on only primary cultured cerebellar granule neurones resulted in significant apoptosis, but the presence of astrocytes largely prevented the effect. The supernatants of the stimulated astrocytes, especially those that contained the highest level of IL-17, achieved the best protection, and this effect could be blocked by anti-IL-17 antibodies. Protein IL-17 inhibited intracellular calcium increase and protected the neurones under inflammatory attack from apoptosis. IL-17, but not interferon (IFN)-γ, in the inflammatory media contributed to astrocyte secretion of IL-17, which depended on the Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway activation. The astrocytes that were treated with IL-17 alone or with prolonged treatment of the inflammatory media failed to produce sufficient levels of IL-17. Moreover, confirmatory data were obtained in vivo in a monophasic experimental autoimmune uveitis (EAU) in Lewis rats; in this preparation, the high-level IL-17-containing the cytokine milieu was demonstrated, along with IL-17 secretion by the resident neural cells. The antagonism of IL-17 at a late stage disturbed the disease resolution and resulted in significant neural apoptosis. Our data show a dynamic role of IL-17 in the maintenance of homeostasis and neuroprotection in active neuroinflammation.

Abstract
A follow-up study questionaires on the quality of life of 130 cases with carcinoma of the esophagus who survived over 10 years postoperatively in our hospital, was conducted from January 1993 to December 1994. Results showed that 82.3% of the patients were able to eat ordinary food, 85.4% of them could carry on regular work and do physical labor, 86.2% of them had high spirits with a sense of well-being. A total number of 88.5% of the patients were very satisfied with their quality of life and 76.9% of them felt excellant. The authors reckoned that both the occurrance of complications in digestive tract and the postoperative mental status play important roles in affecting the quality of life.

Abstract
The level of malondialdehyde (MDA) increased and the activity of superoxide dismutase (SOD) decreased significantly in the aqueous humor 4, 24, and 72 hours after alkali burn in the anterior segment of the rabbit eye. The level of MDA decreased and the activity of SOD increased significantly after subconjunctival injection of exogenous SOD, and the two were negatively correlated. The results suggest that alkali burn causes disturbances in reaction to free radicals, which may be controlled by an early supply of exogenous SOD.

Abstract
Pirprofen was well absorbed by man, rhesus monkey, rat, and mouse after oral administration of a solution of 14C-labeled compound. The major route of elimination of radioactivity in all four species was renal, mostly in the form of metabolites. Twelve metabolites of pirprofen, accounting for 80% or more of the urinary radioactivity, were identified in the urine of the four species. The metabolic pathways of pirprofen involved oxidation to the pyrrole analogue, and oxidation of the pyrroline double bond to an epoxide, followed by opening of the oxirane ring to a trans-diol derivative. Scission of the pyrroline or pyrrole ring was also observed, leading to the corresponding aniline-type metabolite, part of which underwent subsequent acetylation. Conjugation of the propionic acid functionality with glucuronic acid was found to be extensive in the mouse, rhesus monkey, and man, but not in the rat. Conjugation with taurine was also observed in the rat and mouse.
