ABSTRACT

Objective:To investigate the risk factors of moderate to severe pain in patients with non-small cell lung cancer within 3 days after lobectomy.Methods:The clinical data of 297 patients with non-small cell lung cancer who underwent lobectomy in the Department of Thoracic Surgery, Sun Yat-sen University Cancer Center from December 2020 to June 2021 were retrospectively analyzed. A numerical rating scale was used to score the most severe pain within 3 days after surgery. Pain score ≥ 4 was defined as moderate to severe pain. The risk factors for moderate to severe pain were analyzed by binary Logistic regression. General linear model repeated measures and linear mixed models were used to analyze the trend of risk factors influencing postoperative pain with time.Results:The incidence of moderate to severe pain was 34.2% (102/297), 59.8% (178/297), 66.4% (198/297), and 28.2% (84/297) on days 0, 1, 2, and 3 after surgery respectively. The risk for moderate to severe pain was significantly higher in patients undergoing thoracotomy than patients undergoing thoracoscopic surgery on days 1 ( OR = 1.99, P = 0.009), 2 ( OR = 3.08, P < 0.001), and 3 ( OR = 3.88, P < 0.001) after surgery. However, the risk for moderate to severe pain in patients undergoing thoracotomy was slightly, but not significantly, higher than that in patients undergoing thoracoscopic surgery ( OR = 1.53, P = 0.087). The risk for moderate to severe pain was higher in female patients than male patients on day 2 ( OR = 1.62, P = 0.077), and in particular on day 3 after surgery ( OR = 2.39, P = 0.002). Prophylactic use of parecoxib significantly reduced the risk of moderate to severe pain on day 0 ( OR = 0.32, P = 0.004), 1 ( OR = 0.20, P < 0.001), 2 ( OR = 0.36, P < 0.001) and 3 ( OR = 0.56, P = 0.047). Conclusion:The incidence of moderate to severe pain on days 1 and 2 after lobectomy was relatively high in patients with non-small cell lung cancer. Patients undergoing thoracotomy have a higher risk of moderate to severe pain than those who underwent thoracoscopic surgery. Female patients have a higher risk for moderate to severe pain on days 2 and 3 after surgery than male patients. Prophylactic use of parecoxib can decrease the risk for moderate to severe pain in patients with non-small cell lung cancer.

ABSTRACT

ObjectiveTo explore the mechanism of Huangqisan (HQS) in regulating autophagy to alleviate hepatic steatosis and improve non-alcoholic fatty liver disease (NAFLD) based on adenosine 5'-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway. MethodThe main chemical components and targets of HQS and NAFLD-related targets were collected from database and the intersection targets were used for Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. The protein-protein interaction (PPI) network was constructed, and in vivo experimental verification was conducted. Sixty C57BL/6J male mice were randomly divided into normal control group (NCD), model group high-fat diet (HFD), metformin group (MET, 0.25 g·kg-1), low-dose Huangqisan group (HQS-L, 0.5 g·kg-1), and the high-dose Huangqisan group (HQS-H, 1 g·kg-1), with 12 mice in each group after a one-week acclimatization period. NAFLD model was induced by HFD, and intragastric administration was performed at the same time, once a day for 13 weeks. Random blood glucose, serum total cholesterol (TC), triglyceride (TG), non-esterified fatty acid (NEFA), low density lipoprotein-chdesterol (LDL-C) levels, and liver TG content were determined. The liver weight was weighed, and liver index was calculated. Hematoxylin-eosin (HE) staining, oil red O staining, transmission electron microscope (TEM), real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and Western blot were used to verify the effect and reveal the potential mechanism of C57BL/6J mice in vivo. ResultThrough network pharmacology analysis, combined with previous studies, it was predicted that HQS may improve NAFLD by regulating autophagy via the AMPK/mTOR signaling pathway. The result of in vivo experiment showed that, as compared with NCD group, random blood glucose, body weight, serum TC, LDL-C, NEFA, liver weight, liver index, and liver TG content of mice in the HFD groups were significantly increased (P<0.01). HE staining showed massive lipid droplets (LDs) vacuolated, oil red O staining showed lipid accumulation in liver cells, and no obvious autophagosomes and autolysosome were observed under TEM. The relative mRNA expression of LC3A、LC3B、AMPKα1 and protein expression of AMPK, phosphory phosphorylated(p)-AMPK, and p-AMPK/AMPK were significantly down-regulated (P<0.01), while the protein expression of microtubule-associated protein 1 light chain 3 (LC3)Ⅱ/Ⅰ and p-mTOR was significantly up-regulated (P<0.01). As compared with HFD groups, liver weight, serum TG, and NEFA levels in HQS-L and HQS-H groups were significantly deceased (P<0.05, P<0.01). HE staining and oil red O staining showed the improvement of liver pathological changes after HQS administration. Under TEM, a small amount of autophagosome and autolysosome were observed. Besides, liver index was significantly decreased in the HQS-L group (P<0.01), and random blood glucose, serum TC level and liver TG content were significantly decreased in the HQS-H group (P<0.05). The results of Western blot and Real-time PCR showed that the mRNA expression of LC3A and LC3B and the protein expression of LC3Ⅱ/Ⅰ, p-AMPK, and p-AMPK/AMPK were significantly up-regulated (P<0.01), while the mRNA expressions of p62 and protein expression of p62 and p-mTOR were significantly down-regulated (P<0.05, P<0.01). ConclusionHQS may promote autophagy and restore autophagy flux via the AMPK/mTOR signaling pathway to alleviate hepatic steatosis improving NAFLD.

ABSTRACT

Short-chain fatty acids (SCFAs), as the main energy source for colonic epithelial cells, are becoming one of the important nutritional agents in the treatment of E1 (proctitis) and E2 (left-sided) subtypes of ulcerative colitis. To date, the therapeutic effects of topical SCFAs as primary or adjuvant induction therapy have been studied. However, the specific mechanism of action for SCFAs in the pathogenesis and progression of ulcerative colitis needs further investigation. High-quality prospective studies are required to verify current opinions on the selection of SCFA mixtures and the choice of topical or systemic routes of administration. In addition, SCFA is considered as a promising agent to prevent the occurrence and progression of ulcerative colitis-related colorectal cancer. Therefore, the optimal timing to integrate SCFAs into the treatment of ulcerative colitis represents another future research direction.

ABSTRACT

Objective:To investigate the nutritional and metabolic risk factors associated with recurrence in patients with newly diagnosed ulcerative colitis (UC), so as to allow better clinical prediction of recurrence.Methods:A retrospective cohort study was conducted. Patients newly diagnosed with UC (mild and moderate) from the People's Hospital of Xinjiang Uygur Autonomous Region were screened based on prespecified inclusion and exclusion criteria from January 2016 to January 2019. Patients were followed up regularly for three years. Subgroups were determined according to the presence or absence of recurrence. The patients in the UC recurrence group were further stratified according to the time to recurrence into short-term (0-6 months), mid-term (6-12 months) and long-term (12-36 months) recurrence groups. The nutritional and metabolic risk factors related to recurrence were evaluated by univariate analysis and multifactorial logistic regression analysis, and the predictive value was evaluated via receiver operating characteristic curve. The risk factors were then compared across the 3 subgroups with recurrence.Results:A total of 210 patients newly diagnosed with UC (mild and moderate) were included, including 38 experiencing recurrence within 0-6 months, 27 within 6-12 months, 24 within 12-36 months, and 121 without recurrence. There were no statistically significant differences in gender, age, smoking history, and family history in the recurrence group compared with the non-recurrence group. Univariate analysis suggested significant differences in homocysteine, folate, total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), apolipoprotein A/B (ApoA/B), 25-hydroxy vitamin D 3, and body mass index (BMI) between recurrence and non-recurrence groups ( P < 0.05). Multifactorial binary logistic regression analysis suggested that homocysteine ( OR = 0.869, 95% CI: 0.782 to 0.965, P = 0.009), triglycerides ( OR = 0.176, 95% CI: 0.060 to 0.519, P = 0.002), LDL ( OR = 0.256, 95% CI: 0.089 to 0.733, P = 0.011), 25-hydroxy vitamin D 3 ( OR = 0.937, 95% CI: 0.895 to 0.0.982, P = 0.006), and BMI ( OR = 1.319, 95% CI: 1.162 to 1.498, P < 0.01) were independent risk factors for UC recurrence. The predictive efficiency of individual risk factors in descending order was as following: LDL (AUC = 0.762, Youden's index [YI] = 0.42, cut-off value = 2.345), triglycerides (AUC = 0.718, YI = 0.361, cut-off value = 1), homocysteine (AUC = 0.666, YI = 0.283, cut-off value = 13.265). There were no statistically significant differences in gender, age, smoking history, and family history across the short-term, mid-term and long-term recurrence groups. There were significant differences in HDL and ApoA/B levels between the short-term and the long-term recurrence groups ( P < 0.05). Conclusions:Recurrence of the disease in UC patients results from the combined effects of multiple factors. The changes in homocysteine, triglycerides, LDL, 25-hydroxy vitamin D 3, and BMI in UC patients should be proactively monitored to prevent recurrence.

There were 80 males and 26 females,with age range of 25-57 years[(48.6 ± 11.9)years]. Segments of injury were located at T 11 in 18 patients,at T 12 in 26,at L 1 in 21,at L 2 in 25 and at L 3 in 16. All patients were treated with thoracolumbar posterior screw fixation under general anesthesia. Of all,51 patients received conventional postural nursing from June 2018 to May 2019(control group),and 55 patients received prone position nursing scheme for general anesthesia on the basis of conventional postural nursing from June 2019 to May 2020(verification group). The incidence of postoperative complications including stress injury,brachial plexus injury,ulnar nerve injury and ocular discomfort as well as length of hospital stay and patients’ satisfaction were compared between the two groups. Visual analogue scale(VAS)and Oswestry disability index(ODI)were also used to measures outcome at postoperative 3 months. Results:All patients were followed up for 8-12 months[(10.5±0.9)months]. Verification group and control group showed significant differences in the incidence of stress injury(4%∶29%),brachial plexus injury(4%∶16%)and ocular discomfort consisiting of tears(2%∶12%),foreign body sensation(0%∶4%)and dryness(4%∶16%)( P < 0.05),not in ulnar nerve injury and blurred vision. Length of hospitalization in verification group was(7.0±1.3)days,significantly shorter than that in control group[(9.9±1.9)days]( P < 0.05). Satisfaction of patients in verification group and control group was 85%(47/55)and 69%(35/51),respectively( P < 0.05). At 3 months postoperatively,VAS in verification group[(1.9 ± 0.8)points]was significantly lower than that in control group[(3.5±1.1)points]( P < 0.05),and ODI was similar between the two groups( P > 0.05). Conclusions For patients with thoracolumbar fracture treated by posterior surgery with general anaesthesia under prone position,nursing checklist helps reduce occurrence of the related complication,shorten length of hospital stay,improve patient satisfaction,reduce postoperative pain and promote rehabilitation.

ABSTRACT

Recently, the integrated medical curriculum with main line of organ system and with core of disease has played an important role in medical educational reform. During the teaching reform of ultrasonic imaging in the First Affiliated Hospital of Chongqing Medical University, there existed some main problems: simply considering the "integration" as "combination"; unreasonable arrangement of ultrasonic courses; different emphasis on teaching goals between the traditional and integrated teaching; deficient ultrasonic knowledge of clinical teachers, etc.. To solve those problems, teachers participated in the reform must take some measures: firstly, totally understand the spirit of integrated medical reform, and the goal of reform which is improving the clinical ability and quality of medical students but not the pure teaching of medical knowledge; secondly , adjust the curriculum establishment and content of ultrasonic imaging;thirdly, fully utilize the Picture Archiving and Communication System (PACS) system to complement the problem of deficient ultrasonic knowledge of clinical teachers.

ABSTRACT

Objective@#To investigate the urinary metabolic spectrum and pathways in very low birth weight (VLBW) premature infants.@*Method@#A prospective case-control study was conducted to collect and compare the data of VLBW premature infants and full term infants from the Sixth Affiliated Hospital of Sun Yet-Sen University in 2014. Within 24 hours after birth, urine specimens in each group were collected. Metabolites of urine samples including amino acid, fatty acid and organic acid were detected using the urease pre-processing and gas chromatography mass spectrometry (GC-MS) technology. Using the orthogonal partial least squares discriminant analysis (OPLS-DA), the biomarkers and differences between the two groups were found. The online metabolic pathway website was explored and multivariable analysis was conducted to investigate the valuable pathways and biomarkers related to the prematurity.@*Result@#A total of 20 VLBW premature infants were enrolled, among whom 11 were male, 9 were female; and 20 full term infants were enrolled, among whom 9 were male, 11 were female. The urinary metabolites were established and compared between the VLBW premature and term infants. The investigation showed that the following nine pathways were enriched: amino-acyl-tRNA biosynthesis(P=0.000), lysine degradation(P=0.007), fatty acid biosynthesis(P=0.008), pyrimidine metabolism(P=0.014), pantothenate and CoA biosynthesis(P=0.022), valine, leucine and isoleucine biosynthesis(P=0.022), lysine biosynthesis(P=0.031), glycerolipid metabolism(P=0.046), and valine, leucine and isoleucine degradation(P=0.031). Almost all the metabolites decreased except for the glyceric acid exhibiting a higher content in the VLBW premature infant. 12 potential biomarkers were explored with the most significant covariance and correlation, within which stearic acid, palmiticacid, myristic acid, β-amino-isobutyric acid, and uric acid were lower, while myo-inositol, mannitol, glycine, glucose1, glucose2, glyceric acid and N-acetyl-tyrosine were higher in the VLBW premature group compared with the control group.@*Conclusion@#There is a significant difference between the VLBW premature infants and full-term infants in the metabolic state and pathways. The urease pre-processing and GC-MS technology followed by the OPLS-DA and multivariable analysis to investigate VLBW premature infants′ urinary metabolites is a valuable method to evaluate the patients′ metabolism.

Objective To investigate the vessel structure changes of carotid artery with age in normal adults with a newly-developed 3-dimensional ultrasound imaging modality.Methods One hundred and twenty-five normal adult volunteers were divided into five groups:group A,20-29 years old,25 cases;group B,30-39 years old,27 cases;group C,40-49 years old,28 cases;group D,50-59 years old,23 cases;group E,older than 60 years old,22 cases.The straight sections of common carotid arteries were scanned by full-volume three-dimensional ultrasound probe.With a vessel plaque quantification software (VPQ),the following parameters were obtained:intima-media thickness (IMT),vessel total area (VTA),vessel lumen area (VLA),vessel wall area (VWA),and normalized wall index (NWI).Results IMT,VTA,VWA,VLA and NWI were all positively correlated with age (r =0.79,0.48,0.77,0.27 and 0.67 respectively,P =0.00),and there was significant difference among age groups (P <0.01).IMT,VTA,VWA increased with age gradually whereas VLA increased only in group E and NWI showed no significant difference between group E and D.VWA and VTA of males were significantly greater than those of females in group A,B and C,and VLA of males was significantly greater than females in group A and B.There was no significant difference in IMT and NWI between gender groups.Conclusions Age is an important factor to carotid remodeling,and IMT,VTA and VWA increase with age,but VLA keeps constant in people under 60-year-old while NWI becomes stable in people over 50-year-old.It is essential to consider the physiological changes of carotid with age when pathophysiological process of atherosclerosis is involved.

ABSTRACT

Objective To evaluate the effect of dexmedetomidine on spinal p38 mitogen?activated protein kinase ( p38MAPK) expression during remifentanil?induced hyperalgesia in rats with incisional pain. Methods Forty?eight healthy male Sprague?Dawley rats, aged 6 weeks, weighing 220-250 g, were ran?domly divided into 4 groups ( n= 12 each) using a random number table: control group ( group C) , inci?sion pain group ( group IP ) , incision pain + remifentanil group ( group IP+R ) , and incision pain +remifentanil + dexmedetomidine group ( group IP+R+D) . After successful establishment of the model of in?cisionsal pian, remifentanil 1?0μg∕kg was infused for 4 h via the tail vein in group IP+R; remifentanil 1?0μg∕kg was infused for 4 h via the tail vein, and dexmedetomidine 10μg∕kg was simultaneously infused for 4 h via the jugular vein in group IP+R+D; the equal volume of normal saline was infused for 4 h via the tail and jugular veins in C and IP groups. The mechanical paw withdrawal threshold ( MWT) was measured at 24 h before operation ( T0 ) , and at 4, 6, 24 and 48 h after the end of drug infusion ( T1?4 ) . After meas?urement of MWT at T4 , the expression of p38MAPK was determined using immuno?histochemistry. Results was up?regulated at T4 in IP and IP+R groups ( P0?05). Compared with group IP, the MWT was signifi?cantly decreased at T1?4, and the expression of p38MAPK was up?regulated at T4 in group P+R, and the MWT was significantly increased at T1?4, and the expression of p38MAPK was down?regulated at T4 in group IP+R+D (P<0?05). Compared with group IP+R, the MWT was significantly increased at T1?4, and the expression of p38MAPK was down?regulated at T4 in group IP+R+D ( P<0?05) . Conclusion The mecha?nism by which dexmedetomidine reduces hyperalgesia induced by remifentanil is related to down?regulation of spinal p38MAPK expression in the rats with incisional pain.

ABSTRACT

Objective To discuss the effectiveness of community-based intensified health management on type Ⅱ diabetes patients.Metbods From June 2010 to December 2011,1 024 type Ⅱ diabetes patients in Mishi Lane community were enrolled and assigned to the intervention group (n=501,obtaining intensive health management) and the control group (n=523,obtaining routine community health management).Fastingbloodglucose (FBG),2-hour postprandial blood glucose (PBG2h),HbA1c,blood pressure (BP),triglyceride (TG) and body mass index (BMI) were tested and recorded before and after the intervention.Student's t test or Chi-square test were used for data analysis.Results Differences of age (t=0.124,P>0.05) and gender (x2=2.0,P>0.05) were not statistically significant (both P>0.05).Following the intensive health management,the control rates of HbA1c,BP,TG and BMI were increased to 75.4%,30.4%,85.6% and 49.0%,respectively (x2 values were 4.54,4.71,6.54 and 3.67; all P<0.05).TG,FBG and PBG2h of the intervention group were (1.5 ± 0.9),(6.2 ± 1.3) and (8.3 ± 2.4) mmol/L,respectively,which were significantly lower than those of the control group (all P<0.05).Conclusion Community-based intensive health management could be effective for diabetes patients.
