Connexin 43-modified bone marrow stromal cells reverse the imatinib resistance of K562 cells via Ca 2+ -dependent gap junction intercellular communication / 中华医学杂志(英文版)

BACKGROUND@#Imatinib mesylate (IM) resistance is an emerging problem for chronic myeloid leukemia (CML). Previous studies found that connexin 43 (Cx43) deficiency in the hematopoietic microenvironment (HM) protects minimal residual disease (MRD), but the mechanism remains unknown.@*METHODS@#Immunohistochemistry assays were employed to compare the expression of Cx43 and hypoxia-inducible factor 1α (HIF-1α) in bone marrow (BM) biopsies of CML patients and healthy donors. A coculture system of K562 cells and several Cx43-modified bone marrow stromal cells (BMSCs) was established under IM treatment. Proliferation, cell cycle, apoptosis, and other indicators of K562 cells in different groups were detected to investigate the function and possible mechanism of Cx43. We assessed the Ca 2+ -related pathway by Western blotting. Tumor-bearing models were also established to validate the causal role of Cx43 in reversing IM resistance.@*RESULTS@#Low levels of Cx43 in BMs were observed in CML patients, and Cx43 expression was negatively correlated with HIF-1α. We also observed that K562 cells cocultured with BMSCs transfected with adenovirus-short hairpin RNA of Cx43 (BMSCs-shCx43) had a lower apoptosis rate and that their cell cycle was blocked in G0/G1 phase, while the result was the opposite in the Cx43-overexpression setting. Cx43 mediates gap junction intercellular communication (GJIC) through direct contact, and Ca 2+ is the key factor mediating the downstream apoptotic pathway. In animal experiments, mice bearing K562, and BMSCs-Cx43 had the smallest tumor volume and spleen, which was consistent with the in vitro experiments.@*CONCLUSIONS@#Cx43 deficiency exists in CML patients, promoting the generation of MRD and inducing drug resistance. Enhancing Cx43 expression and GJIC function in the HM may be a novel strategy to reverse drug resistance and promote IM efficacy.

Efficacy of different enteral nutrition drugs for severe acute pancreatitis and their gastrointestinal tolerance / 中国药房

OBJECTIVE To compare the efficacy of different enteral nutrition （EN） drugs for severe acute pancreatitis （SAP） and their gastrointestinal tolerance. METHODS A total of 118 SAP patients admitted to the Pancreatic Center of Jiangsu Provincial People’s Hospital from January 1， 2022 to June 30， 2023 were collected and divided into short-peptide EN drugs （SP） group （41 cases）， dietary fiber-free intact protein EN drugs （TP-MCT） group （40 cases） and dietary fiber-containing intact protein EN drugs （TPF-DM） group （37 cases） according to the types of EN. All three groups of patients were given continuous pumps of EN drugs via nasal feeding for 24 hours， with a target energy dose of 25-30 kcal/kg. The blood nutritional indexes [albumin （ALB）， total protein （TP）， hemoglobin （Hb）， globulin （GLB）]， inflammation indexes [white blood cells （WBC）， percentage of neutrophils （N%）， procalcitonin （PCT）， C-reactive protein （CRP）， interleukin-6 （IL-6）]， clinical outcomes indexes [time of stay in the intensive care unit （ICU）， length of hospital stay， duration of resuming oral diet， the rate of cases without improvement， mortality rate] and the occurrence of gastrointestinal tolerance were collected from 3 groups before medication and 7 d after medication. RESULTS After treatment， ALB and TP in 3 groups were significantly higher than before treatment （P＜0.05）； CRP and N% of 3 groups， PCT of TP-MCT group and IL-6 of SP group were significantly lower than corresponding group before medication （P＜ 0.05）； PCT of TP-MCT group and IL-6 of SP group were significantly lower than those of other two groups at corresponding period （P＜0.05）. There were no statistical significances in ALB， TP， CRP or N% among the three groups after medication， and in Hb， GLB or WBC among the three groups before and after treatment （P＞0.05）. There was no significant difference in clinical outcome indexes among 3 groups （P＞0.05）. The incidence of gastrointestinal adverse reactions in the TP-MCT group was the lowest （32.50%）， and significantly lower than those in the SP group （46.34%） and TPF-DM group （48.65%） （P＜0.05）. CONCLUSIONS Different EN preparations can improve the nutritional status and reduce the inflammatory response in SAP patients to different extents， among which SP and TP-MCT are more effective， and TP-MCT shows the better gastrointestinal tolerance.

Mechanism of seahorse ameliorating depression-like behavioral and pathological changes caused by chronic stress in zebrafish / 中国药理学通报

Aim To investigate the effect of marine herbal seahorse on chronic unpredictable mild stress ( CUMS ) -induced depression-like model in zebrafish. Methods Adult zebrafish were divided into control, Stress,Stress + low dose (Stress +0.044% SH) and Stress + high dose (Stress +0. 22% SH) seahorse intervention groups, and depression-like behavior was identified by novel tank test (NTT), cortisol, interleukin ( IL )-6 and interferon (IFN )-γ levels were detected by ELISA. The levels of dopamine (DA) ,norepinephrine (NE), 5-hydroxytryptamine (5-HT) and 5-hydroxyin-doleacetic acid (5-HIAA) were determined by high performance liquid chromatography. The mRNA expression levels of tryptophan hydroxylase(TPH)-2 and 5-HT2A receptor were measured by real-time quantitative PCR. Results Compared with the control group, the Stress group showed significantly longer latency to reach the top in NTT, significantly reduced number of transfers to the top region and top residence time, significantly increased levels of cortisol and IL-6, IFN-γ protein, significantly reduced levels of DA and 5-HT in brain as well as increased metabolism rate of 5-HT, while 5-HT2A mRNA expression was up-regulated and TPH2 mRNA expression was down-regulated. In contrast, low-dose seahorse intervention effectively reduced anxiety, decreased cortisol and IL-6 and IFN-γ concentrations, increased monoamine neurotransmitter levels and reversed dysregulation of the 5-HT ergic system in CUMS zebrafish. Conclusion Seahorse may exert an-tidepressant effects through anti-inflammation and mod¬ulation of monoamine neurotransmitter levels.

Regulation of Yes associated protein in diabetic nephropathy mice by Yishen Huashi Granule / 中国药理学通报

Aim To explore the protective effect of Yishen Huashi Granule (YSHS) on streptozotocin (STZ) - indueed diabetes nephropathy (DN) in mice and its possible mechanism. Methods The STZ induced DN mice model was established, which was randomly divided into model group, YSHS group and YAP inhibitor Vertepofin group, and the eontrol group was also established. The intervention was started eight weeks after the successful modeling with the course of four weeks. Urine protein concentration before and after intervention in each group as well as serum creatinine (Scr) and blood urea nitrogen (Bun) levels after intervention were measured. After the treatment, the mice were sacrificed, and the pathological changes of glomeruli were observed by light microscope HE staining. The protein expression of YAP, p-YAP S127 and CTGF were detected by Western blot, and the mRNA expressions of YAP, CTGF and podocyte functional proteins nephrin, podophyxin and WT1 were detected by RT-PCR. Results The biochemical indexes of YSHS group were better than those of model group, and HE staining showed that the pathological injury of glomeruli was improved. In the model group the protein expression of YAP, p-YAP (S127) and CTGF as well as the mRNA expression of YAP and CTGF increased, while the mRNA expression of nephrin, podocalyxin and WT1 decreased. After YSHS treatment, the protein expression of YAP, p-YAP S127, CTGF and the mRNA expression of YAP and CTGF decreased, while the mRNA expression of nephrin, podocalyxin and WT1 increased. Conclusions YSHS can reduce urinary protein, protect renal function and alleviate glomerular pathological injury in DN mice. Its possible mechanism may be related to the down-regulation of YAP in renal tissue, the reduction of CTGF expression level and the up-regulation of podocyte protein mRNA expression.

Cardiovascular Protective Effect of Shenmai Injection： A Review / 中国实验方剂学杂志

With the improvement of people's living standards and the increasing aging population， the incidence of cardiovascular diseases has sharply risen， making it the leading cause of death and a major "killer" for humans. The prevention and treatment of cardiovascular diseases still face severe challenges. Shenmai injection （SMI）， a Chinese medicinal preparation， is widely used in the prevention and treatment of cardiovascular diseases because of its individualized advantages in syndrome differentiation and definite efficacy. Meanwhile， its pharmacological effects and related mechanism are becoming increasingly clear. Modern research shows that SMI can exert cardioprotective effects by reducing myocardial inflammatory response， alleviating oxidative stress， inhibiting myocardial cell apoptosis， improving microcirculatory dysfunction after myocardial ischemia-reperfusion， protecting mitochondrial structure and function， inhibiting ventricular remodeling， reducing drug-induced cardiotoxicity， and possessing antiviral properties. Additionally， it can produce cardiovascular protection by relaxing blood vessels， protecting endothelial cells， and promoting angiogenesis. Furthermore， SMI can lower blood viscosity and lipid levels， thus improving blood rheology. In the future， more clinical trials and basic research are needed to clarify its therapeutic efficacy and target mechanism to further confirm the effectiveness and safety of its clinical application.

Effects of different crosslinking treatments on the properties of decellularized small intestinal submucosa porous scaffolds / 北京大学学报(医学版)

OBJECTIVE@#To compare the effects of three different crosslinkers on the biocompatibility, physical and chemical properties of decellularized small intestinal submucosa (SIS) porous scaffolds.@*METHODS@#The SIS porous scaffolds were prepared by freeze-drying method and randomly divided into three groups, then crosslinked by glutaraldehyde (GA), 1-ethyl-3-(3-dimethylaminopropyl) carbodi-imide (EDC) and procyanidine (PA) respectively. To evaluate the physicochemical property of each sample in different groups, the following experiments were conducted. Macroscopic morphologies were observed and recorded. Microscopic morphologies of the scaffolds were observed using field emission scanning electron microscope (FESEM) and representative images were selected. Computer software (ImageJ) was used to calculate the pore size and porosity. The degree of crosslinking was determined by ninhydrin experiment. Collagenase degradation experiment was performed to assess the resistance of SIS scaffolds to enzyme degradation. To evaluate the mechanical properties, universal mechanical testing machine was used to determine the stress-strain curve and compression strength was calculated. Human bone marrow mesenchymal cells (hBMSCs) were cultured on the scaffolds after which cytotoxicity and cell proliferation were assessed.@*RESULTS@#All the scaffolds remained intact after different crosslinking treatments. The FESEM images showed uniformed interconnected micro structures of scaffolds in different groups. The pore size of EDC group[(161.90±13.44) μm] was significantly higher than GA group [(149.50±14.65) μm] and PA group[(140.10±12.06) μm] (P < 0.05). The porosity of PA group (79.62%±1.14%) was significantly lower than EDC group (85.11%±1.71%) and GA group (84.83%±1.89%) (P < 0.05). PA group showed the highest degree of crosslinking whereas the lowest swelling ratio. There was a significant difference in the swelling ratio of the three groups (P < 0.05). Regarding to the collagenase degradation experiment, the scaffolds in PA group showed a significantly lower weight loss rate than the other groups after 7 days degradation. The weight loss rates of GA group were significantly higher than those of the other groups on day 15, whereas the PA group had the lowest rate after 10 days and 15 days degradation. PA group showed better mechanical properties than the other two groups. More living cells could be seen in PA and EDC groups after live/dead cell staining. Additionally, the proliferation rate of hBMCSs was faster in PA and EDC groups than in GA group.@*CONCLUSION@#The scaffolds gained satisfying degree of crosslinking after three different crosslinking treatments. The samples after PA and EDC treatment had better physicochemical properties and biocompatibility compared with GA treatment. Crosslinking can be used as a promising and applicable method in the modification of SIS scaffolds.

Anti-tumor Mechanism of Active Ingredients of Glycyrrhizae Radix et Rhizoma and Its Combined Use in Anti-tumor Treatment： A Review / 中国实验方剂学杂志

As a traditional Chinese medicinal material， Glycyrrhizae Radix et Rhizoma has been extensively used in various formulae. According to modern pharmacological research， it has anti-tumor， anti-inflammatory， anti-viral， liver-protecting， anti-heart failure， immunoregulatory， and anti-fibrosis effects. Caused by the interaction of various factors， cancer features complex pathogenesis. It is a global challenge and one of the main causes of death in China. Statistics show that the morbidity and mortality of malignant tumors have been on the rise， particularly for the young， which threaten the health of human beings. At the moment， radiotherapy and chemotherapy are the main countermeasures. Most clinical anti-tumor drugs demonstrate non-selective toxicity. To be specific， they damage normal cells while killing tumor cells， thus injuring vital organs. In addition， long-term medication will reduce the sensitivity of tumor cells. However， traditional Chinese medicine， which is characterized by treatment based on syndrome differentiation， multiple components， and multiple targets， is superior in the treatment of tumor. Studies have shown that the combination of anti-tumor drugs with Chinese medicine can not only enhance the anti-tumor effect but also alleviate toxicity. Therefore， it has been a research hotspot to develop anti-tumor drugs based on traditional Chinese medicine. In recent years， major headway has been made in the research on active ingreddients of Glycyrrhizae Radix et Rhizoma in anti-liver cancer， anti-breast cancer， anti-lung cancer， and anti-colon cancer and the combination with other drugs for anti-tumor. On this basis， we summarized the mechanisms of active ingredients of Glycyrrhizae Radix et Rhizoma in inducing apoptosis， interfering with cell cycle， inducing autophagy， inhibiting glycolysis， regulating immunity， and modulating miRNA and signaling pathways， as well as the combination with other drugs in anti-tumor efficiency， toxicity reduction， and sensitivity enhancement， hoping to lay a theoretical basis for the further development and clinical application of active ingredients of Glycyrrhizae Radix et Rhizoma.

Preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and influencing factors for follow-up compliance: a multicenter investigation / 中国当代儿科杂志

OBJECTIVES@#To investigate the preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and the influencing factors for follow-up compliance.@*METHODS@#A multicenter retrospective case-control study was performed for the cases from the multicenter clinical database of 12 units in the Quality Improvement Clinical Research Cooperative Group of Neonatal Severe Hyperbilirubinemia in Jiangsu Province of China from January 2019 to April 2021. According to whether the follow-up of neonatal jaundice was conducted on time after discharge from the department of obstetrics, the neonates were divided into two groups: good follow-up compliance and poor follow-up compliance. The multivariate logistic regression model was used to identify the influencing factors for follow-up compliance of the neonates before admission.@*RESULTS@#A total of 545 neonates with severe hyperbilirubinemia were included in the study, with 156 neonates (28.6%) in the good follow-up compliance group and 389 (71.4%) in the poor follow-up compliance group. The multivariate logistic regression analysis showed that low gestational age at birth, ≥10% reduction in body weight on admission compared with birth weight, history of phototherapy of siblings, history of exchange transfusion of siblings, Rh(-) blood type of the mother, a higher educational level of the mother, the use of WeChat official account by medical staff to remind of follow-up before discharge from the department of obstetrics, and the method of telephone notification to remind of follow-up after discharge were associated with the increase in follow-up compliance (P<0.05).@*CONCLUSIONS@#Poor follow-up compliance is observed for the neonates with severe hyperbilirubinemia after discharge from the department of obstetrics, which suggests that it is necessary to further strengthen the education of jaundice to parents before discharge and improve the awareness of jaundice follow-up. It is recommended to remind parents to follow up on time by phone or WeChat official account.

A comparative study of artificial intelligence nasal polyp classification based on whole-slide imaging and JESREC diagnostic criteria / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the types and clinical characteristics of chronic rhinosinusitis with nasal polyps (CRSwNP) based on artificial intelligence and whole-slide imaging (WSI), and to explore the consistency of the diagnostic criteria of the Japanese epidemiological survey of refractory eosinophilic chronic rhinosinusitis (JESREC) in Chinese CRSwNP patients. Methods: The data of 136 patients with CRSwNP (101 males and 35 females, aging 14 to 70 years) who underwent endoscopic sinus surgery from 2018 to 2019 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analysed retrospectively. The preoperative clinical characteristics of patients were collected, such as visual analogue scale (VAS) of nasal symptoms, peripheral blood inflammatory cell count, total immunoglobulin E (IgE), Lund-Kennedy score and Lund-Mackay score. The proportion of inflammatory cells such as eosinophils, lymphocytes, plasma cells and neutrophils were calculated on the WSI of each patient through artificial intelligence chronic rhinosinusitis evaluation platform 2.0 (AICEP 2.0), and the specific type of nasal polyps was then obtained as eosinophilic CRSwNP (eCRSwNP) or non-eosinophilic CRSwNP (non-eCRSwNP). In addition, the JESREC diagnostic criteria was used to classify the nasal polyps, and the classification results were compared with the current gold standard for nasal polyps diagnosis (pathological diagnosis based on WSI). The accuracy, sensitivity and specificity of the diagnostic criteria of JESREC were evaluated. The data were expressed in M (Q1, Q3) and statistically analyzed by SPSS 17.0. Results: There was no significant difference between eCRSwNP and non-eCRSwNP in age distribution, gender, time of onset, total VAS score, Lund-Kennedy score or Lund-Mackay score. However, there was a significant difference in the ratio of nasal polyp inflammatory cells (eosinophils 40.5% (22.8%, 54.7%) vs 2.5% (1.0%, 5.3%), neutrophils 0.3% (0.1%, 0.7%) vs 1.3% (0.5%, 3.6%), lymphocytes 49.9% (39.3%, 65.9%) vs 82.0% (72.8%, 87.5%), plasma cells 5.1% (3.6%, 10.5%) vs 13.0% (7.4%, 16.3%), χ2 value was 9.91, 4.66, 8.28, 5.06, respectively, all P<0.05). In addition, eCRSwNP had a significantly higher level of proportion of allergic symptoms (nasal itching and sneezing), asthma, peripheral blood eosinophil and total IgE (all P<0.05). The overall accuracy, sensitivity and specificity of the JESREC diagnostic criteria was 74.3%, 81.3% and 64.3%, respectively. Conclusions: The eCRSwNP based on artificial intelligence and WSI has significant high level of allergic symptoms, asthma, peripheral blood eosinophils and total IgE, and the percentages of inflammatory cells in nasal polyps are different from that of non-eCRSwNP. The JESREC diagnostic criteria has good consistency in our research.

The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.

Research Advance in Mechanism of Cisplatin Toxic Injury and Its Prevention and Treatment by Traditional Chinese Medicine / 中国实验方剂学杂志

Cisplatin， as one of the commonly used broad-spectrum anti-tumor drugs in clinical practice， is used to treat testicular cancer， ovarian cancer， head and neck cancer， bladder cancer， lung cancer， cervical cancer and other solid cancers. It has obvious curative effect but strong toxic and side effect， and is easy to cause great damage to the body. The toxic reaction may involve serious toxic damages to different organs， and induce nephrotoxicity， hepatotoxicity， ototoxicity， cardiotoxicity， neurotoxicity and other toxicity. Animal experiments have shown that the toxic damage induced by cisplatin is the result of many factors in a time-and dose-dependent manner. In the course of clinical use， the therapeutic dose of cisplatin is also greatly limited due to toxic damage， which seriously affects the quality of life in patients. Therefore， it is the main research direction to find a suitable treatment plan or to use drugs in combination with cisplatin to reduce toxicity and increase efficiency. With the increasing clinical participation of traditional Chinese medicine（TCM）， TCM has shown its unique advantages in treating diseases， and can effectively reduce the cisplatin chemotherapy-induced toxic reaction by improving the oxidative stress state of the body， inhibiting normal apoptosis and inflammatory injury， activating autophagy， regulating the abnormal expression of drug transporters， etc. In this paper， the mechanism of cisplatin-induced toxic damage to various organs and the mechanism of TCM in prevention and treatment of cisplatin-induced toxic damage were summarized in detail， including the dose and mechanism of cisplatin-induced toxic damage to different organs， the effective treatment dose， combined medication mode and prevention and treatment mechanism of combined application of TCM and cisplatin， in order to provide a basis for rational application and clinical medication of TCM combined with chemotherapy drugs such as cisplatin.

Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m@*MAIN OUTCOME MEASURES@#The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment.@*RESULTS@#A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group.@*CONCLUSION@#SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.@*TRIAL REGISTRATION NUMBER@#NCT02063100 on ClinicalTrials.gov.

Epidemiological investigation of allergic rhinitis in central cities and countrysides of Inner Mongolia region / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the prevalence of allergic rhinitis (AR) in 3 central cities (Chifeng, Hohhot, Ordos) and the surrounding rural areas of Inner Mongolia region, and to look for possible risk factors related to the disease. Methods: From March to October of 2019, a multi-stage stratified random sampling epidemiological survey was conducted in Chifeng, Hohhot, Ordos and rural areas. The AR-related factors of the population were obtained in the form of face-to-face questionnaire survey, and the skin prick test (SPT) was taken for the participants. AR disease was diagnosed according to the "Guidelines for the Diagnosis and Treatment of Allergic Rhinitis (2015, Tianjin)". The daily airborne pollen situation in the three regions was monitored during the same period. SPSS 23.0 was used to analyze all survey results. Results: A total of 6 818 questionnaires were recovered, with 6 393 valid questionnaires. The self-reported prevalence of AR was 27.72% (1 772/6 393) and the confirmed prevalence of AR was 17.10% (1 093/6 393). The prevalence of perennial AR was 1.83% (117/6 393) while the prevalence of seasonal AR was 15.27% (976/6 393). The prevalence of AR diagnosed in females was higher than that in males (19.19% vs 15.34%, χ²=16.594, P<0.001) and the prevalence of females in the two age groups of 36-45 years and 46-55 years was significantly higher than that of males (18.17% vs 9.73%, 14.13% vs 7.25%, χ2 value was 23.848, 18.772, respectively, all P<0.001). The prevalence of confirmed diagnoses in ethnic minorities was higher than that of Han nationality, and the prevalence of confirmed diagnoses in urban areas was higher than that in rural areas (23.13% vs 16.20%, 27.27% vs 9.71%, χ2 value was 24.516, 336.024, respectively, all P<0.001). The main nasal symptoms of AR patients were sneezing (91.31%), nasal congestion (85.91%) and nasal itching (85.00%). The most common concomitant disease of AR was allergic conjunctivitis (73.99%). Asthma (OR=6.629), food allergy (OR=3.236), drug allergy (OR=1.786), application of antibiotics (OR=1.553), recent home decoration (OR=2.307), and smoking (OR=1.322) were the AR related risk factors. The highest proportion of SPT positive reactions was Artemisia annua (80.15%). The peak period of clinical symptoms of AR patients in Inner Mongolia region was July to September, which was consistent with the second peak period of airborne pollen monitoring. Conclusions: The prevalence of AR in central cities and the surrounding rural areas of Inner Mongolia region is 17.10%, and Artemisia species is the most important pollen allergen in this area. History of asthma, food allergy, drug allergy, antibiotic use, home decoration and smoking history are the related risk factors for AR.

Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants.@*RESULTS@#A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25@*CONCLUSIONS@#The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.

Impact of thymosin α1 as an immunomodulatory therapy on long-term survival of non-small cell lung cancer patients after R0 resection: a propensity score-matched analysis / 中华医学杂志(英文版)

BACKGROUND@#There is limited information about thymosin α1 (Tα1) as adjuvant immunomodulatory therapy, either used alone or combined with other treatments, in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the effect of adjuvant Tα1 treatment on long-term survival in margin-free (R0)-resected stage IA-IIIA NSCLC patients.@*METHODS@#A total of 5746 patients with pathologic stage IA-IIIA NSCLC who underwent R0 resection were included. The patients were divided into the Tα1 group and the control group according to whether they received Tα1 or not. A propensity score matching (PSM) analysis was performed to reduce bias, resulting in 1027 pairs of patients.@*RESULTS@#After PSM, the baseline clinicopathological characteristics were similar between the two groups. The 5-year disease-free survival (DFS) and overall survival (OS) rates were significantly higher in the Tα1 group compared with the control group. The multivariable analysis showed that Tα1 treatment was independently associated with an improved prognosis. A longer duration of Tα1 treatment was associated with improved OS and DFS. The subgroup analyses showed that Tα1 therapy could improve the DFS and/or OS in all subgroups of age, sex, Charlson Comorbidity Index (CCI), smoking status, and pathological tumor-node-metastasis (TNM) stage, especially for patients with non-squamous cell NSCLC and without targeted therapy.@*CONCLUSION@#Tα1 as adjuvant immunomodulatory therapy can significantly improve DFS and OS in patients with NSCLC after R0 resection, except for patients with squamous cell carcinoma and those receiving targeted therapy. The duration of Tα1 treatment is recommended to be >24 months.

Advance in Role of Mitochondria in Remote Ischemic Postconditioning for Cerebral Ischemia-reperfusion Injury (review) / 中国康复理论与实践

Mitochondria, as the key passway of neuronal apoptosis after ischemia, is closely related to cerebral ischemia-reperfusion injury. Remote ischemic post-conditioning can alleviate cerebral ischemia-reperfusion injury, and its mechanism is related to alleviating mitochondrial injury and improving its dysfunction. In this paper, cytochrome C/caspase, mitophagy, mitochondrial ATP-sensitive K+ channel and mitochondrial permeability transitionpore were reviewed.
