ABSTRACT

Hepatic ischemia-reperfusion injury (HIRI) is a very common complication of liver transplantation, liver resection, and shock. At present, many studies have been conducted on HIRI, but there is still a lack of drugs for radical treatment in clinical practice. Many factors, such as related cells, molecular mechanisms and signaling pathways, reactive oxygen species and oxidative stress response, nitric oxide, and mitochondria, mediate the development and progression of HIRI, which leads to the decline of patients' quality of life and even endangers their life safety. Based on the pathogenesis of HIRI and related articles, this article summarizes the research advances in the prevention and treatment of HIRI with traditional Chinese medicine components, so as to provide theoretical support for basic research and clinical research on HIRI.

ABSTRACT

Objective To investigate the risk factors for covert hepatic encephalopathy (CHE) in patients with liver cirrhosis and their influence on prognosis. Methods A total of 416 patients with liver cirrhosis who were hospitalized in a grade A tertiary hospital in Chongqing from September 2019 to June 2020 were enrolled in the study, and according to the presence or absence of CHE, they were divided into CHE group with 212 patients and non-CHE group with 204 patients. Clinical data and laboratory examination results were collected, and follow-up was performed for 6 months. The t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test, the continuous correction chi-square test, and the Mann-Whitney U test were used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to analyze the risk factors for CHE. Results The incidence rate of CHE was 51%. The univariate analysis showed that age, course of disease, the medical history of hepatic encephalopathy (HE), infection, ascites, electrolyte disturbance, hepatorenal syndrome, Child-Pugh class, prothrombin time, total bilirubin, creatinine, platelet, prothrombin activity, albumin, and Model for End-stage Liver Disease (MELD) score were the influencing factors for CHE (all P < 0.05). The multivariate logistic regression analysis showed that the medical history of HE ( OR =10.848, 95% CI : 4.971-23.674, P < 0.05), transjugular intrahepatic portosystemic shunt (TIPS) ( OR =4.334, 95% CI : 1.203-15.621, P < 0.05), Child-Pugh class ( OR =4.968, 95% CI : 1.299-18.992, P < 0.05), and MELD score ( OR =1.253, 95% CI : 1.161-1.352, P < 0.05) were independent predictive factors for CHE ( P < 0.05). The follow-up study showed that CHE had an effect on the short-or medium-term readmission, HE, and death of patients (all P < 0.05). Conclusion CHE has a relatively high incidence rate and greatly affects the prognosis of patients with liver cirrhosis. The development of CHE should be taken seriously in patients with a past history of HE, a history of TIPS, Child-Pugh class C liver function, and a high MELD score, and identification, screening, and intervention should be performed as early as possible to improve the prognosis of patients with liver cirrhosis.

ABSTRACT

Objective To analyze the characteristics, trend and influencing factors of occupational pneumoconiosis in Guizhou, and to provide reference for the prevention and treatment of occupational pneumoconiosis. Methods A total of 1 974 mining patients in Guizhou province were selected from 2019-2020 by stratified sampling survey method. According to whether they were accompanied by occupational pneumoconiosis, they were divided into control group (n=1218) and experimental group (n=756) to analyze the morbidity characteristics, changing trend and influencing factors of occupational pneumoconiosis. Results From 2019 to 2020, 756 (38.30%) of the 1974 mining people in Guizhou suffered from occupational pneumoconiosis, including 602 (79.63%) in stage I, 86 (11.38%) in Stage II, and 68 (8.99%) in stage III. The average age was (57.36±6.89) years, and the average length of service was (15.56±4.47) years. The onset age was mainly from 50 to 69 years, and the difference was statistically significant (χ2=8.214,P2=25.429,P2=8.797,P2=27.212,P<0.05). There were significant differences in age, sex, smoking ratio, length of exposure to dust and complications between the two groups (P<0.05). Logistic regression analysis showed that age, length of dust exposure and complications were independent risk factors for occupational pneumoconiosis (P<0.05). Conclusion The occupational pneumoconiosis in Guizhou area is mainly male, the high incidence age is 50-69 years old, the development is stable, while the incidence of silicosis is increasing in recent years, among which the dust exposure age, age and complications are the high risk factors of occupational pneumoconiosis.

ABSTRACT

Objective@#To investigate the relationship between 18F-FDG PET/CT semi-quantitative parameters and the International Association for the Study of Lung Cancer, American Thoracic Society/European Respiratory Society (IASLC/ATS/ERS) histopathologic classification, including histological subtypes, proliferation activity, and somatic mutations. @*Materials and Methods@#This retrospective study included 419 patients (150 males, 269 females; median age, 59.0 years;age range, 23.0–84.0 years) who had undergone surgical removal of stage IA–IIIA lung adenocarcinoma and had preoperative PET/CT data of lung tumors. The maximum standardized uptake values (SUVmax), background-subtracted volume (BSV), and background-subtracted lesion activity (BSL) derived from PET/CT were measured. The IASLC/ATS/ERS subtypes, Ki67 score, and epidermal growth factor/anaplastic lymphoma kinase (EGFR/ALK) mutation status were evaluated. The PET/CT semiquantitative parameters were compared between the tumor subtypes using the Mann–Whitney U test or the Kruskal–Wallis test. The optimum cutoff values of the PET/CT semi-quantitative parameters for distinguishing the IASLC/ATS/ERS subtypes were calculated using receiver operating characteristic curve analysis. The correlation between the PET/CT semi-quantitative parameters and pathological parameters was analyzed using Spearman’s correlation. Statistical significance was set at p < 0.05. @*Results@#SUVmax, BSV, and BSL values were significantly higher in invasive adenocarcinoma (IA) than in minimally IA (MIA), and the values were higher in MIA than in adenocarcinoma in situ (AIS) (all p < 0.05). Remarkably, an SUVmax of 0.90 and a BSL of 3.62 were shown to be the optimal cutoff values for differentiating MIA from AIS, manifesting as pure ground-glass nodules with 100% sensitivity and specificity. Metabolic-volumetric parameters (BSV and BSL) were better potential independent factors than metabolic parameters (SUVmax) in differentiating growth patterns. SUVmax and BSL, rather than BSV, were strongly or moderately correlated with Ki67 in most subtypes, except for the micropapillary and solid predominant groups. PET/CT parameters were not correlated with EGFR/ALK mutation status. @*Conclusion@#As noninvasive surrogates, preoperative PET/CT semi-quantitative parameters could imply IASLC/ATS/ERS subtypes and Ki67 index and thus may contribute to improved management of precise surgery and postoperative adjuvant therapy.

ABSTRACT

Hepatic ischemia-reperfusion injury (HIRI) is a common clinical problem after hepatectomy and liver transplantation and is the main cause of liver dysfunction and liver failure after transplantation. In recent years, autophagy-mediated pathways have become a research hotspot in alleviating HIRI. Autophagy refers to the process in which a large number of substrates such as cytoplasm and damaged organelles are transported into lysosomes for digestion and degradation, so as to constantly renew, reshape, and reuse cells. This article summarizes the research advances in the mechanism of targeting autophagy to alleviate HIRI from the aspects of gene, protein, signaling pathway, inflammatory response, oxidative stress, and mitochondrial and endoplasmic reticulum stress, as well as existing problems and prospects in research, in order to provide theoretical support for the future research on alleviating HIRI by targeting autophagy.

ABSTRACT

A resurging interest in targeted covalent inhibitors (TCIs) focus on compounds capable of irreversibly reacting with nucleophilic amino acids in a druggable target. p97 is an emerging protein target for cancer therapy, viral infections and neurodegenerative diseases. Extensive efforts were devoted to the development of p97 inhibitors. The most promising inhibitor of p97 was in phase 1 clinical trials, but failed due to the off-target-induced toxicity, suggesting the selective inhibitors of p97 are highly needed. We report herein a new type of TCIs (i.e., FL-18) that showed proteome-wide selectivity towards p97. Equipped with a Michael acceptor and a basic imidazole, FL-18 showed potent inhibition towards U87MG tumor cells, and in proteome-wide profiling, selectively modified endogenous p97 as confirmed by in situ fluorescence scanning, label-free quantitative proteomics and functional validations. FL-18 selectively modified cysteine residues located within the D2 ATP site of p97. This covalent labeling of cysteine residue in p97 was verified by LC‒MS/MS-based site-mapping and site-directed mutagenesis. Further structure-activity relationship (SAR) studies with FL-18 analogs were established. Collectively, FL-18 is the first known small-molecule TCI capable of covalent engagement of p97 with proteome-wide selectivity, thus providing a promising scaffold for cancer therapy.

ABSTRACT

The spread of antibiotic-resistant bacteria and exhausted drug leads render some infections untreatable now and in the future. To deal with these "new challenges", scientists tend to re-pick up "old antibiotics". Fusidane-type antibiotics have been known for nearly 80 years as potent antibacterial agents against gram-positive bacteria, especially Staphylococci, and represent the only triterpene-derived antibiotic class in clinical setting. These attractive characteristics have drawn renewed attention on fusidane-type antibiotics in recent decades. Isolation, characterization, biological evaluation, as well as chemical modifications of fusidane-type antibiotics are increasingly being reported. Combinatorial biosynthesis of this type of antibiotics has been successfully utilized not only for elucidating the biosynthetic pathways, but also for expanding their structural diversity. Some isolated and synthetic compounds exhibit comparable or even more potent biological activity than fusidic acid. This review provides an overview of progress on the studies of structure and biology of fusidane-type antibiotics from 1943 to April 2021. The informative structure-activity relationship is also highlighted.

ABSTRACT

OBJECTIVE@#This study aimed to examine the associations of daytime napping with incident risks of cardiovascular diseases (CVDs) and hypertension (HTN).@*METHODS@#Data for napping and CVD outcomes in 25 provinces were collected from baseline (2010) and three waves of follow-up (2012-2017) investigations of the China Family Panel Studies. Cox frailty models with random intercepts for the surveyed provinces were used to assess the longitudinal effects of daytime napping on CVD and HTN.@*RESULTS@#Compared with non-nappers, 30+ min nappers had higher risks of CVD and HTN, while no significant associations were observed among < 30 min nappers. Incident risks among 30- to < 60-min nappers increased by 22% [hazard ratio (HR) 1.22, 95% confidence interval ( CI) 1.08-1.39] for CVD and 21% (1.21, 1.04-1.41) for HTN, respectively, with corresponding HRs of CVD and HTN of 1.27 (1.09-1.47) and 1.38 (1.16-1.65) among ≥ 60 min nappers. Nap-associated CVD risks varied by subgroups, with stronger associations in participants with lower body mass index (< 24 kg/m 2), physically inactive persons, smokers, and participants with longer nighttime sleep (≥ 7 h/night). Significant effects of daytime napping were observed on rural and northern residents only, highlighting great regional variations in CVD risks associated with napping habits.@*CONCLUSIONS@#This cohort study revealed strong evidence that long daytime napping (≥ 30 min) is associated with an increased incidence of cardiovascular events.

ABSTRACT

OBJECTIVE@#To compare the therapeutic effect between Fanzhen Jieci (warming acupuncture plus fast needling) combined with conventional acupuncture and simple conventional acupuncture on discogenic sciatica.@*METHODS@#A total of 76 patients with discogenic sciatica were randomized into a Fanzhen Jieci group and a conventional acupuncture group, 38 cases in each one. Conventional acupuncture was applied at Shenshu (BL 23), Dachangshu (BL 25), L1-L5 Jiaji (EX-B 2) and Huantiao (GB 30) on the affected side, etc. in the conventional acupuncture group. On the basis of the treatment in the conventional acupuncture group, Fanzhen Jieci was applied at L1-L5 Jiaji (EX-B 2) and Huantiao (GB 30) on the affected side in the Fanzhen Jieci group, i.e. warming acupuncture was applied at L1-L5 Jiaji (EX-B 2), and fast needling was applied at Huantiao (GB 30) on the affected side for a depth of 40-60 mm, so as to introduce a sensation of electric shock transmitting to lower limb, and then the needle was immediately withdrawn. The treatment was given once every other day, 3 times a week for 3 weeks in both groups. The visual analogue scale (VAS) score of leg and low back pain, the Oswestry disability index (ODI) score and the 36-item short form health survey (SF-36) score before and after treatment were compared between the two groups.@*RESULTS@#Compared before treatment, the VAS scores of leg and low back pain and the ODI scores after treatment were decreased in both groups (P<0.001), the changes of the VAS scores of leg and low back pain in the Fanzhen Jieci group were larger than those in the conventional acupuncture group (P<0.05). After treatment, except for the role emotional and health transition scores, the various scores of SF-36 were increased compared before treatment in the Fanzhen Jieci group (P<0.01); except for the role physical, role emotional and health transition scores, the various scores of SF-36 were increased compared before treatment in the conventional acupuncture group (P<0.01). After treatment, the physical functioning, role physical, bodily pain, mental health and general health scores of SF-36 in the Fanzhen Jieci group were higher than those in the conventional acupuncture group (P<0.05).@*CONCLUSION@#Fanzhen Jieci combined with conventional acupuncture can effectively relieve the pain and improve the mental state in patients with discogenic sciatica, its therapeutic effect is superior to simple conventional acupuncture.

ABSTRACT

Objective:To analyze the risk factors of systemic inflammatory response syndrome (SIRS) caused by wasp stings.Methods:A prospective case-control study was conducted to analyze the clinical data of 225 patients with wasp stings admitted to Taihe hospital of Shiyan City and Ankang Central Hospital from January 2014 to December 2018, including 131 males and 94 females, with the age of 49 (41, 60) years. The patients were divided into SIRS group ( n=62) and non-SIRS group ( n=163) according to the SIRS diagnostic criteria. The data were collected including gender, age, sting in the head, sting in waist and back, sting in the abdomen, sting in the limbs, number of stings, admission time, hospitalization day, and mortality. The plasma levels of interleukin(IL)-6 and IL-8 in peripheral blood of the patients were analyzed by ELISA method. The whole genome DNA was extracted from white blood cells, and the IL-6: -174G/C, -572G/C, -597G/A, -634C/G and IL-8: -251A/T, -738T/A, -845T/C, + 396T/G were selected for research. The PCR method was used to perform bidirectional sequencing and comparison after amplification, and record the genotyping and frequency. The risk factors of SIRS caused by wasp stings were investigated by univariate analysis and multivariate Logistics regression analysis. Results:(1) The two groups showed significant differences in sting in the limbs, sting in waist and back, sting in the abdomen, number of stings, hospitalization day and mortality ( P<0.01), while there were no significant differences in gender, age, sting in the head and admission time ( P>0.05). (2) ELISA test showed the plasma levels of IL-6 and IL-8 in SIRS group were higher than those in non-SIRS group ( P<0.01). (3) Three genotypes of CC, GC and GG were observed in IL-6-572G/C. There were significant differences in the frequencies of genotypes and alleles between SIRS group and non-SIRS group ( P<0.01). Three genotypes of AA, AT and TT were observed in IL-8 -251A/T. There were significant differences in the frequencies of genotypes and alleles between SIRS group and non-SIRS group ( P<0.01). (4)Univariate analysis showed sting in waist and back, sting in the abdomen, sting in the limbs, number of stings, IL-6-572G allele, IL-8-251T allele were related to SIRS caused by wasp stings ( P<0.01). (5)Multivariate Logistics regression analysis showed limb stings ( OR=2.15), number of stings ≥10 ( OR=11.10), IL-6-572G allele ( OR=3.91) and IL-8-251T allele ( OR=3.97) were significantly related to SIRS caused by wasp stings ( P<0.05 or 0.01). Conclusions:The plasma levels of IL-6 and IL-8 are increased in patients with SIRS after wasp stings. The limbs stings, number of stings ≥10, IL-6 -572G and IL-8 -251T are all independent risk factors for SIRS caused by wasp stings.

ABSTRACT

Anaplastic lymphoma kinase (ALK) fusion gene, as a tumor driver gene, was crucial for the occurrence and development of non-small cell lung cancer (NSCLC). Recently, targeted ALK fusion gene has become the main treatment method for ALK-positive NSCLC. The first and second generation ALK inhibitors (ALKi), such as crizotinib, ceritinib, alectinib and ensartinib have been approved in China. However, there was no guidance for the management of ALKi adverse reactions. Therefore, this "Recommendations from experts in the management of adverse reactions to ALK inhibitors (2021 version)" has been summarized, led by Lung Cancer Professional Committee of Sichuan Cancer Society and Sichuan Medical Quality Control Center for Tumor Diseases, to provide practical and feasible strategies for clinical ALKi management specification of adverse reactions.

ABSTRACT

OBJECTIVE@#To describe and assess the repair technique and perioperative management for cerebrospinal fluid (CSF) leak resulting from extensive anterior skull base fracture via extradural anterior skull base approach.@*METHODS@#This was a retrospective review conducted at the Department of Neurosurgery of the Shanghai Tenth People's Hospital from January 2015 to April 2020. Patients with traumatic CSF rhinorrhea resulting from extensive anterior skull base fracture treated surgically via extended extradural anterior skull base approach were included in this study. The data of medical and radiological records, surgical approaches, repair techniques, peritoperative management, surgical outcome and postoperative follow-up were analyzed. Surgical repair techniques were tailored to the condition of associated injuries of the scalp, bony and dura injuries and associated intracranial lesions. Patients were followed up for the outcome of CSF leak and surgical complications. Data were presented as frequency and percent.@*RESULTS@#Thirty-five patients were included in this series. The patients' mean age was 33 years (range 11-71 years). Eight patients were treated surgically within 2 weeks; while the other 27 patients, with prolonged or recurrent CSF rhinorrhea, received the repair surgery at 17 days to 10 years after the initial trauma. The mean overall length of follow-up was 23 months (range 3-65 months). All the patients suffered from frontobasal multiple fractures. The basic repair tenet was to achieve watertight seal of the dura. The frontal pericranial flap alone was used in 20 patients, combined with temporalis muscle and/or its facia in 10 patients. Free fascia lata graft was used instead in the rest 5 patients. No CSF leak was found in all the patients at discharge. There was no surgical mortality in this series. Bilateral anosmia was the most common complication. At follow-up, no recurrent CSF leak or meningitis occurred. No patients developed mucoceles, epidural abscess or osteomyelitis. One patient ultimately required ventriculoperitoneal shunt because of progressive hydrocephalus.@*CONCLUSION@#Traumatic CSF rhinorrhea associated with extensive anterior skull base fractures often requires aggressive treatment via extended intracranial extradural approach. Vascularized tissue flaps are ideal grafts for cranial base reconstruction, either alone or in combination with temporalis muscle and its fascia---fascia lata sometimes can be opted as free autologous graft. The approach is usually reserved for patients with traumatic CSF rhinorrhea in complex frontobasal injuries.

ABSTRACT

The neurotoxin β-amyloid (Aβ) is the main hallmark of Alzheimer′s disease (AD). Recent evidence suggests that, in common sporadic or late-onset forms of AD, elevated brain Aβ levels are caused by impaired clearance rather than overproduction. The cell surface receptor′s low-density lipoprotein receptor-related protein-1 (LRP1) has been reported to not only play a role in Aβ endocytosis, but also exist in the blood-brain barrier system, peripheral blood, liver, kidney and other tissues and organs, and transport Aβ to the cerebrospinal fluid or blood system by passing through the blood-brain barrier or the blood-cerebrospinal fluid barrier effectively, and finally clear it out of the body through peripheral tissues and organs. In this review, the role of LRP1 in the peripheral transport and clearance of Aβ is described, and it may be a safe and effective way to reduce Aβ in the brain and even improve cognitive dysfunction.

ABSTRACT

Objective:The aims of this study were to compare the efficacy between salvage liver transplantation (sLT) and rehepatectomy (RR) basing on the propensity score matching (PSM), and to explore the prognositc factors of patients with recurrent hepatocellular carcinoma (HCC).Methods:124 patients with intrahepatic recurrence after hepatectomy in our center from January 2012 to August 2018 were divided into sLT group( n=46) and RR group( n=78). 34 patients were selected for data analysis base on 1∶1 propensity score matching (PSM). The advantages and disadvantages of the two surgical methods and the prognostic factors of the patients were discussed by comparing the basic clinical data, OS and DFS of the two groups before and after matching. Results:Before matching, the pre-operative serum total bilirubin, the occurrence of multiple tumors, the proportion of preoperative TACE and the proportion of patients within Milan criteria of the sLT group were higher than those of the RR group, and the maximum tumor diameter of the sLT group was shorter than that of the RR group ( P<0.05); the time of operation, the amount of intra-operative blood loss, the positive of MVI and the proportion of postoperative Clavien grade Ⅲ and above of RR group were higher than those of RR group ( P<0.05). After matching, the operation time, intra-operative blood loss and the proportion of postoperative complications of sLT group were higher than those of RR group; there was nosignificant difference between 1-, 3- and 5- years OS of sLT group and RR group( P>0.05), the 1-, 3- and 5-years DFS of sLT group were better than those of RR group( P<0.05); AFP≥100 μg/L was the independent risk factor of OS, and the type of operation and AFP≥100 μg/L were independent risk factors of DFS. Conclusions:The pre-operative condition of sLT group was more severe, and the operation time, intra-operative blood loss and post-operative severe complication rate of sLT group were higher than those of RR group, and the DFS time of sLT group was longer than that of RR group, but there was no significant difference in OS between the two groups.

ABSTRACT

Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.

ABSTRACT

Objective:To evaluate the positive rate of the bronchodilation test (BDT) in asthmatic children with normal forced expiratory volume in 1 second (FEV 1), forced vital capacity (FVC) and FEV 1/FVC, so as to improve the recognition of the importance of the BDT test in asthmatic children with normal FEV 1, FVC and FEV 1/FVC. Methods:Children aged 5-14 who were diagnosed with asthma in the outpatient clinic of Shandong Provincial Hospital Affiliated to Shandong University from September 2018 to August 2019 and willing to receive pulmonary function and BDT examinations were enrolled.Data of pulmonary function of children with normal FEV 1, FVC and FEV 1/FVC were collected to analyze the rate of positive BDT results and the status of small airway function. Results:A total of 1 631 asthmatic children with normal FEV 1, FVC and FEV 1/FVC were enrolled in this study, including 1 414 children with normal pulmonary function and 217 children with small airway dysfunction.Fifteen minutes after the bronchodilator was inhaled, 127 children (87 males and 40 females) showed positive BDT results, accounting for 7.8%.Among these children, 62 cases (28.6%) with co-existing small airway dysfunction showed positive BDT results.The improvement rate of FEV 1 was 8.0% to 11.9% in 132 cases (8.1%). The FEV 1 before bronchodilator inhalation accounted for (98.5±10.3)% of the predicted value.Fifteen minutes after terbutaline sulfate inhalation, the improvement rate was 13.5% (12.5%, 16.2%). The improvement rates of forced expiratory flow at 50% of FVC exhaled (FEF 50, r=-0.339, P<0.01), forced expiratory flow at 75% of forced vital capacity exhaled (FEF 75, r=-0.400, P<0.01), maximum mid-expiratory flow(MMEF, r=-0.375, P<0.01) were negatively correlated with their baseline values.The improvement rate of FEV 1 was not associated with its baseline value ( r=-0.128, P=0.153), but negatively correlated with the baseline value of MMEF ( r=-0.231, P<0.01). Conclusions:BDT results are positive in some asthmatic children with normal FEV 1, FVC and FEV 1/FVC.It is recommended that BDT testing should be conducted as much as possible in the diagnosis and follow-up of children with typical or atypical asthma.In this way, the diagnosis can be confirmed and the current optimal results can be obtained.Meanwhile, small airway function testing is helpful for comprehensive assessment of asthma and its control level.

OBJECTIVE@#To investigate the action mechanisms of electroacupuncture (EA) on postoperative immunosuppression.@*METHODS@#Male C57BL/6 mice (5`-7 weeks old) were randomly divided into: the sham injury group, the surgical trauma stressed group, the EA group [surgery + 2/100 Hz EA at Neiguan (PC 6)], and the EA+ Nal (surgery + EA + intraperitoneal injection of naloxone). Abdominal surgical trauma stress mice model was established. EA was performed on bilateral PC 6 acupoints by an EA apparatus (2/100 Hz) for 20 min once a day for 3 days. The mRNA expressions of MOR, DOR, and KOR in thymus and L3`-L5 dorsal root ganglions (DRG) were determined by quantitative real-time polymerase chain reaction (qRT-PCR) and the protein expressions of MOR, DOR, and KOR in thymus were measured by Western blot. Flow cytometry assay was used to detect the levels of T lymphocyte subtypes in the peripheral blood.@*RESULTS@#Surgical trauma induced decreased the mRNA expression level of MOR in both thymus (P0.05). Furthermore, T lymphocyte population of CD3@*CONCLUSION@#EA may improve postoperative immunosuppression through the peripheral opioid system.

ABSTRACT

Laparoscopic radical resection of left hemicolon cancer is difficult in lymph node dissection, splenic flexure dissociation and digestive tract reconstruction. The high resolution recognition ability of 4K laparoscopic system can help complete mesocolic excision and neuroprotec-tion of the left colon. The authors discuss the key points of 4K totally laparoscopic radical resection of left hemicolon cancer and intraperitoneal overlap digestive reconstruction through surgical examples.

ABSTRACT

Objective:To summarize and evaluate the domestic and foreign evidence on the intervention and management of neuropathic pain in patients with spinal cord injury, so as to provide evidence-based basis for clinical nursing staff.Methods:According to "6S" evidence model of evidence pyramid, computer evidence retrieval was carried out. Expert consensus and evidence summary quality assessment used the corresponding evaluation criteria of JBI evidence-based Health Care Centers (2016), while evidence-based guidelines quality used AGREE Ⅱinstrument, and high quality evidence was extracted.Results:A total of 6 articles, including 5 guidelines and 1 expert consensus, were included in this study. A total of 22 pieces of evidence were extracted, including the assessment, intervention measures, feedback, education and nursing model of neuropathic pain in patients with spinal cord injury.Conclusion:This study summarizes the evidence for the intervention and management of pathologic pain in spinal cord injury, which can provide scientific basis for clinical nursing staff. As the evidence summarized in this study comes from many countries, sufficient evaluation of clinical environment and other related factors should be conducted before application to promote the quality of nursing.
