Objective To provide the practical basis for clinical diagnosis and treatment of patients who were admitted by green channel because of vomiting and abdominal pain. Method 268 cases with vomiting andabdominal pain ( from January 2007 to December 2008 ) who were admitted into the emergency observation unit through green channel were retrospectively analyzed, and various risk factors were considered with logistic regression model. Result Among 268 cases, 34 kinds of different diseases were found,while gastrointestinal diseases were the greatest proportion [60. 1% (161/268)] and gastroenteritis was most common reason 77.6%( 125/161 ). Between different age groups ( ≤ 3-year-old group and>3-yearold group), the overall incidence of various diseases and the profile of disease was different (P<0.05).The incidence of diseases in the digestive tract, infectious diseases and surgical between two groups was statistically different (P<0.05). Between inpatient admission and non-inpatient admission patients, single logistic regression showed that there was significantly different between the nine events (age, fever, shock,duration of symptoms, blood routine test( BRT), liver function, blood Na+, blood / urine amylase, electrocardiogram) ( P <0.05). In the regression model, all showed significant difference except BRT. Conclusion Most of patients with vomiting and abdominal pain were digestive system diseases. Patients ≤ 3years old had a higher incidence of infectious and surgical diseases. The patients who accompanied by fever,shock and laboratory tests such asliver function, blood Na +, blood / urine amylase, electrocardiogram were abnormal would have higher hospitalize rate.

Objective To explore the seed protein extraction method for Amomum villosum Lour., so as to lay the foundation for the study of differential proteomics of Amomum villosum Lour. during seed dormancy and germination. Methods We used the four kinds of commonly-used protein extraction methods for the experiment, including Tris-HCl extraction method, trichloroacetic acid (TCA) /acetone precipitation method, direct lysis buffer method and improved Tris-saturated phenol method. The obtained proteins were quantified, and then were analyzed by sodium dodecyl sulphate- polyacrylamide gel electrophoresis (SDS-PAGE) . Results The protein yield was the highest when using direct lysis buffer method, which was mainly composed of small molecule protein. The protein yield was the lowest using Tris/HCl method, characterized by the diffused stripes in SDS-PAGE spectra. The protein yield was moderate using TCA/acetone method and improved Tris-saturated phenol method, and the obtained protein by the TCA/acetone method had less stripes in SDS-PAGE spectra than that by Tris-saturated phenol method, and was characterized by macromolecular protein. Conclusion The combination of direct lysis buffer extraction method and improved Tris-saturated phenol method may provide reference for seed protein extraction method of two-dimensional electrophoresis for Amomum villosum Lour..

[ ABSTRACT] AIM:To screen out a suitable lead for monitoring the ambulatory electrocardiogram ( ECG) in un-restrained toad, and to investigate its practicability.METHODS:After subcutaneously implanting the electrodes in toads under anaesthesia, the ambulatory ECG of 5 leads were monitored with BL-420S data acquisition and analysis system, and the leads which could well express the waveform in ECG were screened out.The recovery process of the toads from the arti-ficial hibernation within 6 h, the day-to-day stability of the heart rate ( HR) and the heart rate variability ( HRV) in 5 suc-cessive days of hibernation, and the HR and HRV after freeze-thawing process were monitored to determine its practicabili-ty.RESULTS:Two out of 5 leads showed better ECG waveforms.Compared with 6 h post hibernation, lowered HR at 0 h and 1 h was observed, and the standard deviation of normal R-R intervals ( SDNN) was significantly increased ( P<0.05 or P<0.01), but the HR and SDNN from 2 to 5 h showed no significant difference, suggesting that the cardiac function reached the steady state after 2 h recovery.The HR at 2 h and 4 h on day 4 and day 5 decreased significantly compared with that on day 1 (P<0.05 or P<0.01), followed with a significant increase in SDNN (P<0.05 or P<0.01), sugges-ting that the ECG remained stable within 3 d.The HR increased, while SDNN decreased significantly at 1 h and 12 h post-thawing compared with that at pre-freeze (P<0.05), indicating the damaged cardiac function after freeze-thawing process. CONCLUSION:The method of subcutaneously implanting electrodes is suitable for effectively monitoring the ambulatory ECG in toads.

Objective:To investigate the effect of intraoperative body temperature on prognosis of elderly patients with strangulated small bowel obstruction.Methods:The clinical data of 113 elderly patients with strangulated small intestinal obstruction and perform partial resection and anastomosis admitted to the Affiliated Hospital of Southwest Medical University from December 2017 to June 2022 were retrospectively analyzed. The ROC curve was used to analyze the relationship between the intraoperative body temperature(T) and the prognosis of patients, so as to obtain the optimal cutoff point (Ta). According to the relationship between T and Ta, all patients were divided into hypothermia group (33 cases) (T

AIM:To investigate the effects of saponin from Panax japonicus IVa(SPJ IVa)on acute lung inju-ry in rats and to explore its possible protective mechanism.METHODS:Sixty SD rats were randomly divided into four groups,15 rats in each group:the control group,model group,low-dose SPJ IVa group,and high-dose SPJ IVa group.A rat model of ALI was established via intratracheal instillation of lipopolysaccharide(LPS,2 mg/kg).Rats in the low-and high-dose SPJ IVa groups were intraperitoneally injected with 15 and 45 mg/kg SPJ IVa,respectively,30 min after model-ing.Serum,bronchoalveolar lavage fluid(BALF),and lungs were collected 24 h after modeling.Pathomorphological changes in lung tissues were assessed using HE staining.The wet weight/dry weight ratio of lung tissues was measured us-ing the weighing method,whereas ELISA was used to measure the levels of interleukin-1β(IL-1β),IL-6,and tumor ne-crosis factor-α(TNF-α)in the serum and BALF.The levels of malondialdehyde(MDA),superoxide dismutase(SOD),and glutathione(GSH)were assessed using the kit method.Cell apoptosis in lung tissues was evaluated by immunohisto-chemical staining of cleaved caspase-3 and TUNEL.Western blot was used to measure the expression of nuclear factor E2-related factor 2(Nrf2),heme oxygenase-1(HO-1),nuclear factor-κB(NF-κB)p65,and Toll-like receptor 4(TLR4)in lung tissues.RESULTS:Compared with control group,the lung tissues of the model group were significantly damaged,and the lung injury scores(0.21±0.22 vs 2.98±0.46)and lung wet/dry weight ratios(3.09±0.41 vs 6.36±0.61)were significantly increased(P<0.01).Compared with model group,the lung injury scores(1.80±0.31 and 1.05±0.25 vs 2.98±0.46)and lung wet/dry weight ratios(5.25±0.44 and 3.89±0.35 vs 6.36±0.61)in low-and high-dose SPJ IVa groups were significantly reduced(P<0.01).The administration of LPS resulted in elevated levels of pro-inflammatory cy-tokines(IL-1β,IL-6,and TNF-α)as well as the oxidative marker MDA in both serum and BALF(P<0.01).Additional-ly,it led to a decrease in antioxidant markers SOD and GSH(P<0.01).However,treatment with both low and high doses of SPJ IVa effectively attenuated the LPS-induced production of pro-inflammatory factors and oxidative markers MDA(P<0.01),while also increasing SOD and GSH levels(P<0.05 or P<0.01).In the model group,evident apoptosis was ob-served in lung tissues,whereas treatment with low and high doses of SPJ IVa significantly suppressed TUNEL-positive cells and the expression of cleaved caspase-3(P<0.01).The expression levels of Nrf2,HO-1,NF-κB p65,and TLR4 in lung tissues were significantly higher in the model group than in the control group(P<0.01);in turn,after treatment with low and high doses of SPJ IVa,Nrf2 and HO-1 were further upregulated(P<0.01),whereas NF-κB p65 and TLR4 were downregulated(P<0.01).CONCLUSION:The inhibitory effect of SPJ IVa on LPS-induced ALI in rats may be attribut-ed to its ability to suppress the TLR4/NF-κB-and Nrf2/HO-1-mediated inflammatory response and oxidative stress.

Objective:To investigate the risk factors, severity of symptoms, acute exacerbations, and pulmonary function in women with chronic obstructive pulmonary disease (COPD).Methods:A total of 4 204 COPD patients, including 533 female COPD patients and 3 671 male COPD patients, were investigated from January 2017 to December 2019 in Second Xiangya Hospital of Central South University, Hunan Prevention and Treatment Institute for Occupational Disease, affiliated Hospital of Guilin Medical College and Guilin Second People's hospital. The risk factors, severity of symptoms, risk of acute exacerbation and clinical characteristics of pulmonary function in patients with COPD were comprehensively analyzed.Results:There was no statistical difference in age between male and female COPD patients ( P>0.05). There were statistically significant differences in smoking history, occupational exposure history and biofuel exposure history ( P<0.001), among which smoking history and occupational exposure history were significantly higher in males than in females ( P<0.001), and exposure history of biofuels was significantly higher in females than in males ( P<0.001). The COPD assessment test (CAT) score of male and female patients was statistically different ( P<0.05), and the mean CAT score of female patients was higher than that of male patients. The modified medical research council dyspnea scale (mMRC) grading results of male and female patients were statistically different ( P<0.05), and the mMRC grading of female patients was higher than that of male patients. There was no statistical difference in the risk of acute exacerbation between male and female patients ( P>0.05). There were statistically significant differences between male and female patients in first second exertional volume as a percentage of predicted value (FEV 1%) and forced expiratory volume in one second/forced vital capacity (FEV 1/FVC) mean value ( P<0.001), and FEV 1% predicted value and FEV 1/FVC of female patients were better than that of male patients. Conclusions:The risk factors, symptom severity and pulmonary function of female patients with COPD are different from those of male patients, providing reference for the individualized treatment of female patients with COPD.

A middle aged male presented with darkened skin and edema of lower extremities was reported. He was diagnosed as primary adrenocortical insufficiency ( Addison' s disease ) accompanied with hypergonadotropic hypogonadism, hypoparathyroidism, and subclinical hypothyroidism after endocrinological workup. In addition, the patient also had thickened skin, hirsutism, and polyserositis. The diagnosis of POEMS syndrome was confirmed by elevated M protein and VEGF level. The image of CT showed normal adrenals. Besides the autoimmune polyglandular syndrome ( APS), the possibility of POEMS syndrome in an adult patient with multiple endocrine dysfunction should be considered.

Objective To compare the production of farnesol between Candida albicans (C.albicans) biofilms formed by resistant and standard strains in different media,and to investigate the changing trend of farnesol production in different phases of biofilm formation and the features of farnesol production by resistant C.albicans.Methods Fluconazole-resistant C.albicans strains were induced in vitro.Standard strains and fluconazole-resistant strains of C.albicans were separately inoculated onto different media,including RPMI 1640 medium,yeast extract peptone dextrose (YPD) medium,yeast nitrogen base (YNB) + 0.5％ glucose medium,RPMI 1640 + 10％ fetal calf serum (FCS),so as to form C.albicans biofilms.Morphological changes of C.albicans biofilms at 24 hours were observed under an inverted microscope,and gas chromatography-mass spectrometry (GC/MS)was performed to detect the level of farnesol at 1.5,3,6,12,24,36 and 48 hours.Results There were no obvious differences in the morphology of C.albicans biofilms between the resistant and standard strains when they were cultured in the same medium,while the morphology of C.albicans biofilms markedly differed between the 2 kinds of strains in the different media.Three-factor analysis of variance showed that the production of farnesol in the C.albicans biofilms changed over time (F =70.628,P ＜ 0.001).Concretely speaking,during the formation of resistant and standard C.albicans biofilms,the production of farnesol gradually increased in the RPMI 1640,YPD and YNB + 0.5％ glucose media until the biofilms matured,then showed a decreasing trend.However,the time to peak levels of farnesol was different between the 2 kinds of strains in these media.Moreover,the levels of farnesol in the 2 kinds of strains both slowly increased in the RPMI 1640 + 10％ FCS medium within 12-48 hours.Culture media also significantly affected the production of farnesol (F =176.665,P ＜ 0.001),and the levels of farnesol in the resistant and standard C.albicans biofilms were both higher in the YNB + 0.5％ glucose medium.When resistant and standard strains were separately cultured in the RPMI 1640 media and the YPD media,the level of farnesol was significantly higher in the resistant strains than in the standard stains (RPMI 1640 media at 36 hours:1.157 ± 0.064 vs.0.250 ± 0.075,P ＜ 0.05;YPD media at 6 hours:0.262 ± 0.036 vs.0.055 ± 0.062,P ＜ 0.05;YPD media at 12 hours:0.730 ± 0.030 vs.0.482 ± 0.024,P ＜ 0.05).However,when they were separately cultured in the YNB + 0.5％ glucose media,the farnesol level was significantly higher in the standard stains than in the resistant strains (36 hours:2.950 ± 0.677 vs.0.523 ± 0.266,P =0.020).Conclusion The media markedly affect the production of farnesol in the C.albicans biofilms,and there is a certain difference in the production of farnesol between resistant and standard C.albicans strains.
