Acteoside promotes autophagy and apoptosis of hepatoma cells by regulating JNK signaling pathway / 中国中药杂志

This study explored the molecular mechanism of acteoside against hepatoma 22(H22) tumor in mice through c-Jun N-terminal kinase(JNK) signaling pathway. H22 cells were subcutaneously inoculated in 50 male BALB/c mice, and then the model mice were classified into model group, low-dose, medium-dose, and high-dose acteoside groups, and cisplatin group. The administration lasted 2 weeks for each group(5 consecutive days/week). The general conditions of mice in each group, such as mental status, diet intake, water intake, activity, and fur were observed. The body weight, tumor volume, tumor weight, and tumor-inhibiting rate were compared before and after administration. Morphological changes of liver cancer tissues were observed based on hematoxylin and eosin(HE) staining, and the expression of phosphorylated(p)-JNK, JNK, B-cell lymphoma-2(Bcl-2), Beclin-1, and light chain 3(LC3) in each tissue was detected by immunohistochemistry and Western blot. qRT-PCR was performed to detect the mRNA expression of JNK, Bcl-2, Beclin-1, and LC3. The general conditions of mice in model and low-dose acteoside groups were poor, while the general conditions of mice in the remaining three groups were improved. The body weight of mice in medium-dose acteoside group, high-dose acteoside group, and cisplatin group was smaller than that in model group(P<0.01). The tumor volume in model group was insignificantly different from that in low-dose acteoside group, and the volume in cisplatin group showed no significant difference from that in high-dose acteoside group. Tumor volume and weight in medium-dose and high-dose acteoside groups and cisplatin group were lower than those in the model group(P<0.001). The tumor-inhibiting rates were 10.72%, 40.32%, 53.79%, and 56.44% in the low-dose, medium-dose, and high-dose acteoside groups and cisplatin group, respectively. HE staining showed gradual decrease in the count of hepatoma cells and increasing sign of cell necrosis in the acteoside and cisplatin groups, and the necrosis was particularly obvious in the high-dose acteoside group and cisplatin group. Immunohistochemical results suggested that the expression of Beclin-1, LC3, p-JNK, and JNK was up-regulated in acteoside and cisplatin groups(P<0.05). The results of immunohistochemistry, Western blot, and qRT-PCR indicated that the expression of Bcl-2 was down-regulated in the medium-dose and high-dose acteoside groups and cisplatin group(P<0.01). Western blot showed that the expression of Beclin-1, LC3, and p-JNK was up-regulated in acteoside and cisplatin groups(P<0.01), and there was no difference in the expression of JNK among groups. qRT-PCR results showed that the levels of Beclin-1 and LC3 mRNA were up-regulated in the acteoside and cisplatin groups(P<0.05), and the level of JNK mRNA was up-regulated in medium-dose and high-dose acteoside groups and cisplatin group(P<0.001). Acteoside promotes apoptosis and autophagy of H22 cells in mice hepatoma cells by up-regulating the JNK signaling pathway, thus inhibiting tumor growth.

ABSTRACT Introduction: Skeletal muscle satellite cells are considered the unique source of stem cells for myogenic differentiation of adult skeletal muscle cells. Upon stimulation, the skeletal muscle satellite cell can be activated through specific signaling pathways, proliferate and differentiate into a muscle cell. An analysis of the effects of key signaling pathways could provide the basis for an in-depth study of skeletal muscle formation in athletes and muscle development. Objective: This paper analyzes the effects of key signaling pathways on skeletal muscle satellite cell proliferation and differentiation. Methods: We divided 32 athletes into four groups: control, stretching, experimental, and mixed groups. The control group received no training at all, the stretching group and the experimental group received stretching training on the right gastrocnemius. The mixed group also got weight climbing training in the stretching training, initial load 30% of the athlete's weight, increasing 25% each week until 100% of body weight, at the frequency of 3 times a week. After training, gene expression of live satellite cells was measured by intramuscular signaling. Results: The FGM level of the antagonistic group (3.56±0.21) was higher than in the control group (3.25±0.18). The gene expression of HGF mRNA was higher in the mixed group (2.16±0.24) followed by the antagonistic group (2.02±0.15), the stretching group (1.81±0.25), and the control group (1.03±0.06). Conclusion: Both stretching and antagonistic training can increase gene expression in signaling pathways. Antagonistic training significantly increased the expression of HGF, MGF, and mRNA. This activity can promote muscle bulking and skeletal muscle enlargements. Evidence Level II; Therapeutic Studies - Investigating the result.

Mutual Information Entropy Analysis of Compatibility of Traditional Chinese Patent Medicines Against Liver Diseases in Chinese Pharmacopoeia（2020 Edition） / 中国实验方剂学杂志

ObjectiveTo investigate the compatibility rule of traditional Chinese patent medicines （TCPMs） against liver diseases through network analysis. MethodWith “liver” as the search term， TCPMs against liver diseases were retrieved from volume Ⅰ of Chinese Pharmacopoeia （2020 edition）， and the basic information of them was collected. TCPMs with same Chinese medicinal materials （CMMs）， usage， and indications， but different dosage forms， were unified as one formula. Mutual information entropy （MIE） of CMM couples was calculated to quantify the relationship between them， and the top 25% CMM pairs in MIE were used to construct the compatibility network， with CMM as node and the relationship between CMM pairs as the edge. Key CMM and frequently used CMM combinations were identified based on node centrality and cluster analysis， respectively. The indications of TCPMs related to the CMMs in clusters were recorded. Cytoscape 3.6.1 was employed for visualization and topology analysis of the compatibility network. ResultA total of 179 TCPMs， involving 428 CMMs， were retrieved. Angelicae Sinensis Radix， Paeoniae Radix Alba， and Glycyrrhizae Radix et Rhizoma were identified as key CMMs with high frequency， and Cuscutae Semen-Lycii Fructus， Citri Reticulatae Pericarpium-Cyperi Rhizoma， and Ecliptae Herba-Ligustri Lucidi Fructus combinations had high MIE. Furthermore， the CMMs were clustered into ten groups corresponding to different diseases which， however， all belonged to digestive diseases. ConclusionThis study unveils potential CMM pairs and common CMM combinations against liver diseases， which can serve as a reference for revealing compatibility rules of CMMs and research and development of Chinese medicine.

The clinical application value of seven tumor-associated autoantibodies in the diagnosis of non-small cell lung cancer / 中华检验医学杂志

Objective@#This study was designed to evaluate the clinical value of seven combinedtumor-associated autoantibodies (7-TAAB) in the diagnosis of non-small cell lung cancer (NSCLC).@*Methods@#This is a cross-sectional study. The 81 newly diagnosed patients with NSCLC were enrolled. 46 patients with benign pulmonary diseases (BLD) and 55 healthy subjects were selected as the BLD group and the healthy control (HC) group, respectively. ELISA was used to detect the concentration of seven TAABs of p53, PGP9.5, SOX2, GAGE7, GBU4-5, MAGE A1 and CAGE in the serum of the NSCLC and the other two groups. The levels of lung cancer tumor markers CEA, NSE, SCC and CYFRA21-1 in serum were also detected in all enrolled subjects. Kruskal-wallis test was used for comparison among the three groups, Mann-Whitney test was used to evaluate the differences between the two groups, and positivity rates were analyzed by using standard χ2 tests and Fisher exact tests. The receiver operating characteristic (ROC) analyses were performed to evaluate the diagnostic efficacy of 7-TAAB or combination of 7-TAAB and traditional tumor markers.@*Results@#The serological levels of six TAABs (p53, SOX2, GAGE7, GBU4-5, MAGE A1, and CAGE) in the NSCLC group were higher than that in the BLD group (p53: Z=-4.370, P=0.000; SOX2: Z=-4.412, P=0.000; GAGE7: Z=-4.250, P=0.001; GBU4-5: Z=-2.678, P=0.025; MAGE A1: Z=-4.504, P=0.002; CAGE: Z=-4.646, P=0.001) and the HC group (p53: Z=-3.543, P=0.000; SOX2: Z=-3.383, P=0.002; GAGE7: Z=-4.893, P=0.001; GBU4-5: Z=-3.381, P=0.025; MAGE A1: Z=-3.369, P=0.001; CAGE: Z=-2.981, P=0.002),respectively. The differences were statistically significant. The comparison of PGP9.5 in NSCLC group with that in the BLD group was statistically significant (Z=-2.871, P=0.044), with that in the HC group was no difference (Z=-2.280, P=0.05). None of the seven TAABs showed a significant difference between the BLD group and the HC group (p53: Z=-1.917, P=0.917; PGP9.5: Z=-1.228, P=0.966; SOX2: Z=-1.789, P=0.325; GAGE7: Z=-0.563, P=1.000; GBU4-5: Z=-0.315, P=0.985; MAGE A1: Z=-2.310, P=0.857; CAGE: Z=-2.822, P=0.703). According to the criteria of cut-off value, the detection value of individual TAAB was judged as negative or positive. The specificity of every single TAAB to NSCLC was ≥89%, but the sensitivity was ≤39.5%. Positive in any of the single TAAB was considered as a positive result of 7-TAAB, the positive rate of 7-TAAB in NSCLC subgroups with early stages (stageⅠand stageⅡ) was considered higher than that of traditional biomarkers (7-TAAB:52.94%, CEA: 23.53%, NSE: 8.82%, CYFRA21-1∶20.59%, SCC:14.71%), and 7-TAAB was more sensitive to NSCLC patients with poor prognosis, such as advanced stages (stageⅢand stageⅣ) and moderately-poorly differentiation. The AUC of 7-TAAB was 0.734, with a sensitivity of 66.67% and a specificity of 80.20%. In coordination with 7-TAAB, CEA, NSE, CYFRA21-1 and SCC, the AUC was 0.917, with a sensitivity of 87.70% and a specificity of 81.20%.@*Conclusions@#7-TAAB, regarded as a panel of serological markers, is helpful in NSCLC diagnosis and shows broad application prospect. The detection rate of 7-TAAB in patients with early NSCLC is superior to that of traditional serum tumor markers, and the combination of 7-TAAB with CEA, NSE CYFRA21-1 and SCC could improve the diagnosis sensitivity of patients with NSCLC.

Results The serological levels of six TAABs (p53, SOX2, GAGE7, GBU4-5, MAGE A1, and CAGE) in the NSCLC group were higher than that in the BLD group (p53: Z=-4.370, P=0.000;SOX2:Z=-4.412, P=0.000;GAGE7:Z=-4.250, P=0.001;GBU4-5:Z=-2.678, P=0.025;MAGE A1:Z=-4.504, P=0.002;CAGE:Z=-4.646, P=0.001) and the HC group (p53:Z=-3.543, P=0.000;SOX2:Z=-3.383, P=0.002;GAGE7:Z=-4.893, P=0.001;GBU4-5:Z=-3.381, P=0.025;MAGE A1:Z=-3.369, P=0.001;CAGE:Z=-2.981, P=0.002),respectively. The differences were statistically significant. The comparison of PGP9.5 in NSCLC group with that in the BLD group was statistically significant (Z=-2.871, P=0.044), with that in the HC group was no difference (Z=-2.280, P=0.05). None of the seven TAABs showed a significant difference between the BLD group and the HC group (p53: Z=-1.917, P=0.917; PGP9.5: Z=-1.228, P=0.966;SOX2:Z=-1.789, P=0.325;GAGE7:Z=-0.563, P=1.000;GBU4-5:Z=-0.315, P=0.985;MAGE A1:Z=-2.310, P=0.857;CAGE:Z=-2.822, P=0.703). According to the criteria of cut-off value, the detection value of individual TAAB was judged as negative or positive. The specificity of every single TAAB to NSCLC was≥89％, but the sensitivity was≤39.5％. Positive in any of the single TAAB was considered as a positive result of 7-TAAB, the positive rate of 7-TAAB in NSCLC subgroups with early stages (stageⅠand stageⅡ) was considered higher than that of traditional biomarkers (7-TAAB:52.94％, CEA:23.53％, NSE:8.82％, CYFRA21-1:20.59％, SCC:14.71％), and 7-TAAB was more sensitive to NSCLC patients with poor prognosis, such as advanced stages (stageⅢand stageⅣ) and moderately-poorly differentiation. The AUC of 7-TAAB was 0.734, with a sensitivity of 66.67％and a specificity of 80.20％. In coordination with 7-TAAB, CEA, NSE, CYFRA21-1 and SCC, the AUC was 0.917, with a sensitivity of 87.70％ and a specificity of 81.20％.Conclusions 7-TAAB, regarded as a panel of serological markers, is helpful in NSCLC diagnosis and shows broad application prospect. The detection rate of 7-TAAB in patients with early NSCLC is superior to that of traditional serum tumor markers, and the combination of 7-TAAB with CEA, NSE CYFRA21-1 and SCC could improve the diagnosis sensitivity of patients with NSCLC.

Application of VATS in Diagnosis and Treatment of Lung Cancer Complicated with Pneumothorax / Aplicação do VATS no Diagnóstico e Tratamento do Câncer de Pulmão Complicado com Pneumotórax

The paper aims to explore clinical symptoms and complication characteristic of lung cancer complicated with pneumothorax, analyze clinical diagnostic value of VATS, and elaborate on specific clinical programs and significance. To investigate diagnosis and therapeutic value of VATS for lung cancer complicated with pneumothorax, 1900 cases of patients with lung cancer complicated with pneumothorax were randomly selected as research objects to be treated with VATS, and then analysis of their clinical data was done. The clinical data showed that many patients were not clearly diagnosed before operation. In VATS operation, lung tumor tissue was removed and then immediately frozen and sliced. Appropriate surgical approach was chosen based on specific circumstances of patients. As can be known from the results, 1000 cases were treated with wedge resection of lung tumor under thoracoscopy, 900 cases were treated with assisted small incision surgery under thoracoscopy. 1400 cases of lung metastasis were treated with pleural friction fixation. All the operations were successful, with pathology being clearly diagnosed. After surgery, 8 patients had mild air leakage, which could be heal without special treatment. There was no perioperative death. The above analysis shows that VATS can clearly diagnose peripheral lung tumor, and fundamentally cure pneumothorax and lung cancer, which is thus recommended in clinic.

o artigo pretende explorar sintomas clínicos e complicações características do câncer de pulmão complicado com pneumotórax, analisar o valor do diagnóstico clínico do VATS e elaborar programas e significados clínicos específicos. Para investigar o diagnóstico e valor terapêutico do VATS para câncer de pulmão complicado com pneumotórax, 1900 casos de pacientes com câncer de pulmão complicado com pneumotórax foram selecionados aleatoriamente como objetos de pesquisa para serem tratados com VATS e, em seguida, foi feita a análise de seus dados clínicos. Os dados clínicos mostraram que muitos pacientes não foram corretamente diagnosticados antes da operação. Na operação VATS, o tecido do tumor pulmonar foi removido e imediatamente congelado e cortado em fatias. A abordagem cirúrgica apropriada foi escolhida com base em circunstâncias específicas dos pacientes. Como pode ser conhecido a partir dos resultados, 1000 casos foram tratados com ressecção em cunha do tumor pulmonar sob toracoscopia, 900 casos foram tratados com cirurgia de incisão pequena assistida sob toracoscopia. 1400 casos de metástases pulmonares foram tratados com fixação de fricção pleural. Todas as operações foram bem-sucedidas, sendo a patologia claramente diagnosticada. Após a cirurgia, 8 pacientes apresentaram vazamento de ar leve, que pode ser curado sem tratamento especial. Não houve morte perioperatória. A análise acima mostra que a VATS pode diagnosticar claramente o tumor pulmonar periférico, e fundamentalmente curar pneumotórax e câncer de pulmão, o que é recomendado na clínica.

In vitro chemokine (C-C motif) receptor 6-dependent non-inflammatory chemotaxis during spermatogenesis

BACKGROUND: Chemokine (C-C motif) receptor 6 (CCR6) is present in sperm and plays a significant role in sperm motility and chemotaxis acting in the reproductive tracts. However, the expression and functional significance of CCR6 in testis are still poorly understood, especially in the process of spermatogenesis. METHODS AND RESULTS: CCR6 was expressed in spermatogenic cell lines and its expression was shown in an age-dependent upregulation manner from puberty to adulthood in mouse testis. Immunostaining results confirmed the localization of CCR 6 in testis. Further chemotaxis assays demonstrated that spermatogenic cells GC-1 and -2 exhibited a directional movement toward CCR6-specific ligand such as CCL20 or Sertoli cells in vitro. CONCLUSIONS: The present findings indicate that CCR6 is involved in the chemotaxis of spermatogenic cells in vitro and promotes chemotaxis under non-inflammatory conditions during normal spermatogenesis.

Comparison of Oncoplastic Breast-Conserving Surgery and Breast-Conserving Surgery Alone: A Meta-Analysis / 한국유방암학회지

PURPOSE: The use of oncoplastic reconstruction for breast-conserving surgery (BCS) extends benefits beyond merely minimizing poor cosmetic results. However, the feasibility and oncological safety of oncoplastic surgery (OPS) are controversial. METHODS: This meta-analysis aimed to compare the short-term and long-term oncological outcomes of BCS alone and BCS plus OPS. Relevant studies published before July 2017 in the Embase, the Cochrane Library, PubMed, and Web of Science databases were screened and collected. The meta-analysis was performed using STATA software (Stata Corp.). RESULTS: A total of 3,789 patients from 11 studies were included, with 2,691 patients in the BCS-alone group and 1,098 patients in the BCS plus OPS group. The demographics were similar between both groups, and no significant difference was observed in pathological T and N stages between the two groups. Re-excision was less common (relative risk [RR], 0.66; p=0.009) and the positive-margin rate was lower, but not significantly (RR, 0.83; p=0.191), in the BCS plus OPS group than in the BCS-alone group. The local and distal recurrence rates were similar in both groups. Both disease-free survival (hazard ratio [HR], 1.19; 95% confidence interval [CI], 0.96–1.49; p=0.112) and overall survival (HR, 1.14; 95% CI, 0.76–1.69; p=0.527) did not differ between the two groups. CONCLUSION: A combination of BCS and OPS is preferred over BCS alone for decreasing re-excisions and provides similar long-term survival as BCS alone in patients with breast cancer.

Neuropsychological Functioning after Adenotonsillectomy in Children with Obstructive Sleep Apnea: A Meta-analysis / 华中科技大学学报（医学）（英德文版）

The present study aimed to investigate the efficacy of adenotonsillectomy (AT) for children with obstructive sleep apnea syndrome (OSAS) and the improvement of their cognitive function.Studies on cognitive performance of OSAS children treated with or without AT were identified by searching the Pubmed,EMBASE and Cochrane library.A meta-analysis was conducted to analyze the literature.The random-effects model was used to evaluate 11 eligible studies using an inverse-variance method.The neuropsychological test results of 4 cognitive domains (general intelligence,memory,attention-executive function and verbal ability) were obtained and analyzed.By comparison of cognitive function between OSAS children and healthy controls,the effect sizes of each domain were achieved as follows:general intelligence,-0.5 (P＜0.0001);memory,-0.18 (P=0.02);attention-executive function,-0.21 (P=0.002);and verbal ability,-0.48 (P=0.0006).The effect sizes of general intelligence,memory,attention-executive function,and verbal ability after AT compared to baseline level were-0.37 (P=0.008),-0.36 (P=0.0005),-0.02 (P=0.88),and-0.45 (P=0.009),respectively.Comparing the cognitive ability between OSAS children after AT and healthy controls showed that the effect sizes were-0.54 (P=0.0009),-0.24 (P=0.12),-0.17 (P=0.35),and-0.45 (P=0.009) in general intelligence,memory,attention-executive function,and verbal ability,respectively.Our results confirmed that OSAS children performed worse than healthy children in terms of the 4 cognitive domains investigated.After 6-12 months of observation,significant improvement in attention-executive function and verbal ability were found in OSAS children treated with AT compared to their baseline level;restoration of attention-executive function and memory were observed in OSAS children after AT in comparison to healthy controls.Further rigorous randomized controlled trials should be conducted to obtain definitive conclusions.

Effect of Recurrent Severe Hypoglycemia on Cognitive Performance in Adult Patients with Diabetes: A Meta-analysis / 华中科技大学学报（医学）（英德文版）

The purpose of this study was to investigate the existence and extent of cognitive impairment in adult diabetes mellitus (DM) patients with episodes of recurrent severe hypoglycemia,by using meta-analysis to synthesize data across studies.PubMed,EMBASE and Cochrane library search engines were used to identify studies on cognitive performance in DM patients with recurrent severe hypoglycemia.Random-effects meta-analysis was performed on seven eligible studies using an inverse-variance method.Effect sizes,which are the standardized differences between the experimental group and the control group,were calculated.Of the 853 studies,7 studies met the inclusion criteria.Compared with control subjects,the adult DM patients with episodes of recurrent severe hypoglycemia demonstrated a significantly lowered performance on memory in both types of DM patients,and poor performance of processing speed in type 2 DM patients.There was no significant difference between adult DM patients with and those without severe hypoglycemia in other cognitive domains such as general intelligence,executive function,processing speed and psychomotor efficiency.Our results seem to confirm the hypothesis that cognitive dysfunction is characterized by worse memory and processing speed in adult DM patients with a history of recurrent severe hypoglycemia,whereas general intelligence,executive function,and psychomotor efficiency are spared.

Health human resource development cooperation in China's foreign aid: Situation analysis and improvement strategies / 中国卫生政策研究

Health Human Resource Development Cooperation(HHRDC) is a critical component in Chinese foreign aid,which had cultivated thousands of health workers for Asian and Arican developing countries by on-job training,degree education,short-term exchange activities for more than 60 years.This paper systematically reviewed the management mechanism,mode and features of HHRDC via literature review,stakeholders interviews and field investigations,and it is found that the main mode of HHRDC is short-term on-job training,but its effect for capacity building is limited;although degree education account for a small proportion of HHRDC,it plays an important role for elite cultivation;the impact for medical team teaching and technical cooperation have become more obvious;the "going out" training have less invest,short period,but bigger social impact.The main challenges of HHRDC includes the deficiency of specific strategies and action plans;the lack of understanding on recipient countries' health human resource situation,characteristics and needs;the alignment with other aid programs;the lack of timely evalu ation towards current cooperation projects.According to the need analysis of undeveloped countries,it is suggested that a cooperation plan for HHDRC is required;the implementation of HHRDC should integrate into other aid programs;the follow-up mechanism and evaluation system need improved;the Chinese degree certification and qualification in local institutions need promoted;the aid to medical educational institutions should added,thereby strengthening developing countries' capacity and realizing common development.
