A case-control study on gut microbiota diversity and species composition in obese/overweight children aged 2-6 years in Shanghai / 环境与职业医学

Background Multiple studies have shown a close relationship between changes in gut microbiota composition and obesity, and research results are influenced by factors such as race and geographical location, but there are few studies on children. Objective To analyze the diversity of gut microbiota related to obesity in a population of 2-6 years old, observe the distribution characteristics and species differences of gut microbiota between obese/overweight and normal weight groups, and explore the association betweenobese/overweight and gut microbiota diversity. Methods Fecal samples were collected from 74 children aged 2-6 years in Shanghai, including 18 obese/overweight individuals, 6 males and 12 females (male to female ratio of 1∶2), and 56 normal weight individuals, 18 males and 38 females (male to female ratio is nearly 1∶2). The 16S rDNA was extracted from bacteria in fecal samples, followed by PCR amplification, cDNA construction, and high-throughput sequencing. Naive Bayes algorithm was used to perform taxonomic analysis (phylum, class, order, family, genus, species) and community diversity analysis (Sobs index, Shannon index, Shannoneven index, Coverage index, PD index, and principal co-ordinates analysis) on representative sequences and abundance of amplicon sequence variants (ASV). Wilcoxon rank sum test, P-value multiple test correction, and analysis of similarities were used to test differences between the two groups to obtain information on the distribution characteristics and species differences of intestinal microbiota in children. Results Seventy-four fecal samples were sequenced, and the sequencing results were subjected to quality control and filtering. A total of 4905306 optimized sequences were obtained, resulting in 1860 ASVs. The diversity data analysis of ASVs generated 889 species annotation results at 8 taxonomic levels. The alpha diversity analysis showed that the richness (Sobs index), diversity (Shannon index), evenness (Shannoneven index), and phylogenetic diversity (PD index) of fecal community of the obese/overweight children were increased compared to those of the normal weight children, but there were no statistical differences between the two groups (P>0.05). The beta diversity analysis showed that there was little difference in the composition of microbial species between the two groups, and no significant clustering separation was observed. The results of species composition analysis at phylum, order, family, and genus levels of 74 samples showed a consistent core microbiota structure in the two groups of gut microbiota, but there were differences in microbiota composition. The differences in microbial community composition between the two groups were manifested at the taxonomic levels of order, family, and genus, among which phylum Firmicutes, order Erysipelotrichales, family Erysipelatocyclostridiaceae, genus Erysipelotrichaceae_ UCG-003 and genus Catenibacterium were significantly enriched in the obese/overweight group and contributed significantly to the phenotypic difference of obese/overweight [linear discriminant analysis (LDA)=3.72, P<0.01; LDA=3.29, P<0.05). Phylum Proteobacteria, order Enterobacterales, family Enterobacteriaceae, genus unclassified was significantly enriched in the normal weight group and contributed significantly to the phenotypic difference of normal body weight (LDA=3.93, P<0.05). Conclusion The richness and diversity of gut microbiota in obese/overweight children aged 2-6 years in Shanghai are increased, but there is no difference compared to normal weight children. There is a difference in the composition of gut microbiota between the obese/overweight group and the normal weight group.

Research Progress of Parallel Chart and Its Application in Traditional Chinese Medicine / 中国医学伦理学

With the rapid development of modern biomedicine, subjective factors such as human emotion and disease experience are diluted. Accurate data, programmed diagnosis and treatment process and other objective factors cut off the effective communication between doctors and patients, aggravating the already tense doctor-patient relationship and intensifying various conflicts in the clinic. In order to improve clinical humanistic care, medical and nursing workers have launched reflections and explorations. Narrative medicine is a new form of medical humanistic practice, while parallel chart, as an important way of its practice, records patients’ subjective experiences and painful feelings. It is of great theoretical significance and clinical value to sinicize narrative medicine and construct and promote parallel chart in Traditional Chinese Medicine (TCM) by studying the research progress of parallel chart in China and its application in TCM.

Reshaping the Cortical Connectivity Gradient by Long-Term Cognitive Training During Development / 神经科学通报·英文版

The organization of the brain follows a topological hierarchy that changes dynamically during development. However, it remains unknown whether and how cognitive training administered over multiple years during development can modify this hierarchical topology. By measuring the brain and behavior of school children who had carried out abacus-based mental calculation (AMC) training for five years (starting from 7 years to 12 years old) in pre-training and post-training, we revealed the reshaping effect of long-term AMC intervention during development on the brain hierarchical topology. We observed the development-induced emergence of the default network, AMC training-promoted shifting, and regional changes in cortical gradients. Moreover, the training-induced gradient changes were located in visual and somatomotor areas in association with the visuospatial/motor-imagery strategy. We found that gradient-based features can predict the math ability within groups. Our findings provide novel insights into the dynamic nature of network recruitment impacted by long-term cognitive training during development.

OBJECTIVE To establish a UPLC-MS/MS method for the determination of plasma concentration of three carbapenem antibiotics， i.e. ertapenem （ETP）， imipenem （IPM） and meropenem （MEM）. METHODS After protein precipitation with methanol， the plasma samples were separated by ACQUITY UPLC BEH C18 column （2.1 mm×50 mm， 1.7 μm） using stable isotopes of three antibiotics （ETP-D4， IPM-D4， MEM-D6） as the internal standard. The mobile phases were 98% acetonitrile +2% water +0.1% formic acid and 98% water +2% acetonitrile +0.1% formic acid， by gradient elution. The flow rate was 0.3 mL/min and the column temperature was 40 ℃. Scanning analysis was performed in the positive ion and multiple reaction monitoring mode. RESULTS The method had good specificity， good linearity （r2≥0.993） in the range of 0.2-200， 0.1-100 and 0.1-100 μg/mL of ETP， IPM and MEM， and good intra-batch and inter-batch precision and accuracy （all RE≤5.14%， all RSD≤11.15%）， the matrix effect and extraction recovery were consistent （RSD≤12.99%）. CONCLUSIONS This study establishes the UPLC-MS/MS method to simultaneously quantify the plasma concentration of ETP， IPM and MEM. The method has the advantages of simple pretreatment， short detection time and small sample quantity to meet clinical requirement.

Establishment of a rat model with aortic dissection induced by β-aminopropionitrile combined with angiotensin Ⅱ / 中国胸心血管外科临床杂志

@#Objective    To investigate the optimal administration combination of β-aminopropionitrile (BAPN) and Angiotensin Ⅱ (Ang-Ⅱ) in the establishment of SD rat aortic dissection (AD) model and the related complications. Methods    Forty-two three-week-old male SD rats were randomly divided into 7 groups: a group A (0.25% BAPN), a group B (0.40% BAPN), a group C (0.80% BAPN), a group D [1 g/(kg·d) BAPN], a group E [1 g/(kg·d) BAPN+ 1 μg/(kg·min) saline], a group F [1 g/(kg·d) BAPN+1 μg/(kg·min) Ang-Ⅱ] and a group G (control group). There were 6 rats in each group. The intervention period was 4 weeks (groups E and F were 4 weeks+5 days). Rats were dissected immediately if they died during the experiment. After the intervention, the surviving rats were sacrificed by pentobarbital sodium, and the whole aorta was separated and retained. Hematoxylin-eosin staining was used to observe the changes of aorta from the pathological morphology. Results    There was no statistical difference in the survival rate among the groups after 4 weeks of BAPN intervention (P>0.05). After 5 days of mini-osmotic pumps implantation, the survival rate of rats was higher in the group E than that in the group F (P=0.008), and the incidence of AD in the group E was lower than that in the group F (P=0.001). BAPN could affect the food and water intake of rats. After BAPN intervention for 4 weeks, the body weight of rats in the group G was higher than those in the intervention groups (P<0.05). BAPN combined with Ang-Ⅱ could make the aortic intima thick, elastic fiber breakage, arrangement disorder, and inflammatory cell infiltration in rats, which conformed to the pathological and morphological changes of AD. BAPN could also affect mental state and gastrointestinal tract. Conclusion    The combination of BAPN [1 g/(kg·d)] and Ang-Ⅱ [1 μg/(kg·min)] can stably establish AD model in rats, which will provide a stable carrier for further study of the pathogenesis and therapeutic targets of AD. However, the complications in this process are an unstable factor. How to balance the influence of BAPN on other tissues and organs in the process of AD model establishment remains to be further studied.

Mechanisms of brain damage caused by inorganic fluoride using proteomics-based techniques / 环境与职业医学

Background Chronic excessive exposure to fluoride can cause damage to the central nervous system and a certain degree of learning and memory impairment. However, the associated mechanism is not yet clear and further exploration is needed. Objective Using 4D unlabelled quantitative proteomics techniques to explore differentially expressed proteins and their potential mechanisms of action in chronic excessive fluoride exposure induced brain injury. Methods Twenty-four SPF-grade adult SD rats, half male and half male, were selected and divided into a control group and a fluoride group by random number table method, with 12 rats in each group. Among them, the control group drank tap water (fluorine content<1 mg·L−1), the fluoride group drank sodium fluoride solution (fluorine content 10 mg·L−1), and both groups were fed with ordinary mouse feed (fluoride content<0.6 mg·kg−1). After 180 d of feeding, the SD rats were weighed, and then part of the brain tissue was sampled for pathological examination by hematoxylin-eosin (HE) staining and Nissl staining. The rest of the brain tissue was frozen and stored at −80 ℃. Three brain tissue samples from each group were randomly selected for proteomics detection. Differentially expressed proteins were screened and subcellular localization analysis was performed, followed by Gene Ontology (GO) function analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, cluster analysis, and protein-protein interaction analysis. Finally, Western blotting was used to detect the expression levels of key proteins extracted from the brain tissue samples. Results After 180 d of feeding, the average weight of the rats in the fluoride group was significantly lower than that in the control group (P<0.05). The brain tissue stained with HE showed no significant morphological changes in the cerebral cortex of the fluoride treated rats, and neuron loss, irregular arrangement of neurons, eosinophilic changes, and cell body pyknosis were observed in the hippocampus. The Nissl staining results showed that the staining of neurons in the cerebral cortex and hippocampus of rats exposed to fluoride decreased (Nissl bodies decreased). The proteomics results showed that a total of 6927 proteins were identified. After screening, 206 differentially expressed proteins were obtained between the control group and the fluoride group, including 96 up-regulated proteins and 110 down-regulated proteins. The differential proteins were mainly located in cytoplasm (30.6%), nucleus (27.2%), mitochondria (13.6%), plasma membrane (13.6%), and extracellular domain (11.7%). The GO analysis results showed that differentially expressed proteins mainly participated in biological processes such as iron ion transport, regulation of dopamine neuron differentiation, and negative regulation of respiratory burst in inflammatory response, exercised molecular functions such as ferrous binding, iron oxidase activity, and cytokine activity, and were located in the smooth endoplasmic reticulum membrane, fixed components of the membrane, chloride channel complexes, and other cellular components. The KEGG significantly enriched pathways included biosynthesis of secondary metabolites, carbon metabolism, and microbial metabolism in diverse environments. The results of differential protein-protein interaction analysis showed that the highest connectivity was found in glucose-6-phosphate isomerase (Gpi). The expression level of Gpi in the brain tissue of the rats in the fluoride group was lower than that in the control group by Western blotting (P<0.05). Conclusion Multiple differentially expressed proteins are present in the brain tissue of rats with chronic fluorosis, and their functions are related to biosynthesis of secondary metabolites, carbon metabolism, and microbial metabolism in diverse environments; Gpi may be involved in cerebral neurological damage caused by chronic overdose fluoride exposure.

OBJECTIVE To construct the “school-enterprise-community” linkage community pharmaceutical care mode based on the WeChat mini program， upgrade the content and mode of community pharmaceutical care， and improve the quality of healthy life of the residents. METHODS Focusing on the pharmaceutical care needs of community residents， by integrating school， enterprise and community pharmaceutical resources， the WeChat mini program of “drug enjoying health” was created and the “online+offline” community pharmaceutical care mode was built. Using classified random sampling， mini program users were randomly selected as the observation group， and offline pair-assisted community residents as the control group. The intervention effects of the two groups were compared around the three aspects of medication health knowledge mastery， medication compliance and medication behavior. RESULTS The “drug enjoying health” mini program consisted of four modules：“ drug for health”，“ drug for warmth”，“ drug for safety”， and “personal information”. The “school-enterprise-community” linkage community pharmaceutical care mode based on the “drug enjoying health” mini program began to be applied in July 2022， with 6 185 users， 2 732 recovery records of expired drugs， 941 times of pharmaceutical care， and 3 354 consultation orders. After the intervention， the qualified rate of medication health knowledge mastery， complete compliance rate， and the correct rate of medication behavior in the observation group increased from 33.53% to 76.87%， 20.23% to 46.26%， and 49.71% to 89.80%， respectively； the proportion of the increase after the intervention was higher than that of the control group （P＜0.05）. CONCLUSIONS This mode has effectively improved the quality of community pharmaceutical care， improves the health awareness of community residents in drug use， and promotes the standardization， rationalization and safety of residents’ drug use.

The Effect of Modified Shugan Dingji Decoction （疏肝定悸汤） on the Occurrence of Endpoint Events in Patients with Paroxysmal Atrial Fibrillation of Liver Constraint and Qi Stagnation： A Retrospective Cohort Study / 中医杂志

ObjectiveTo retrospectively analyze the effect of modified Shugan Dingji Decoction （疏肝定悸汤） on the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation. MethodsA retrospective cohort study was conducted using the electronic medical record database of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine to screen and include patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation from January 1st， 2018， to December 31th， 2021. The included patients were divided into an exposure group and a non-exposure group， each consisting of 100 cases， based on whether they received modified Shugan Dingji Decoction. General information of the patients including age， gender， body mass index， duration of illness and comorbidities， medication history， cardiac structure and function indicators such as left atrial diameter， left ventricular end-diastolic diameter， stroke volume and ejection fraction， and the occurrence of endpoint events assessed through 24-hour dynamic electrocardiography or electrocardiogram to determine the recurrence of paroxysmal atrial fibrillation were collected. Kaplan-Meier （K-M） curves and Log-Rank tests were used to conduct survival analysis on the occurrence of endpoint events in the two groups of patients. Univariate and multivariate Cox regression analyses were used to analyze the impact of various factors on entry into endpoint events. Additionally， a safety assessment was performed by comparing liver and kidney function indicators before and after treatment. ResultsIn the non-exposure group， a total of 49 cases （49.0%） experienced endpoint events， while in the exposure group， there were 26 cases （26.0%）. The Log-rank test indicated significant difference between the two groups （χ2=11.211， P=0.001）. Univariate Cox regression analysis showed that age， duration of illness， hypertension， diabetes， chronic heart failure， left atrial diameter， stroke volume， and the use of modified Shugan Dingji Decoction may be the influencing factors for the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation （P＜0.05 or P＜0.01）. Multivariate Cox regression analysis showed that the risk of endpoint events in the exposure group was significantly lower than that in the non-exposure group （P＜0.01）. Patients with a duration of illness ＞12 months had a significantly higher risk of endpoint events compared to those with a duration of illness ≤12 months （P＜0.01）. Patients without concomitant hypertension had a lower risk of endpoint events compared to those with hypertension （P＜0.05）. Patients with left atrial diameter ＞40 mm had significantly higher risk of endpoint events than those with left atrial diameter ≤40 mm （P＜0.01）. There was no statistically significant difference in liver and kidney function indicators between the two groups before and after treatment （P＞0.05）. ConclusionThe use of modified Shugan Dingji Decoction is a protective factor for patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation， which can help to reduce the recurrence and progression of atrial fibrillation. Long duration of illness， concomitant hypertension， and enlarged left atrial diameter are risk factors for patients to experience endpoint events.

Furthermore, hiPSCs co-cultured with corneal stromal cells exhibited LSCs markers ABCG5 and corneal epithelial cell precursor markers CK15 were positive; however, corneal epithelial cell markers CK3 and CK12 were negative. With the addition of BMP4 and SB431542, hiPSCs showed positive expression of CK3, and the CK3 expression increased over the time.CONCLUSION: With the addition of SB431542 and BMP4, hiPSCs cultured in simulated LSCs microenvironment could differentiate into corneal epithelial cells.

Hsa_circ_0013561 promotes progression of nasopharyngeal carcinoma by activating JAK2/STAT3 signaling pathway

Abstract Objective Nasopharyngeal Carcinoma (NPC) is a malignancy of epithelium of epithelium of the nasopharynx, with the highest incidence of otolaryngeal malignancies. A growing number of studies confirm that Circular RNA (circRNA) plays an important role in tumor development, including Hsa_circ_0013561. This study aims to elucidate the process and mechanism of NPC regulation hsa_circ_0013561. Methods In this study, circRNA expression nodes and subcellular localization in NPC tissues were analyzed by fluorescence in situ hybridization. The expression of hsa_circ_0013561 in NPC cells was further clarified by RT-qPCR. At the same time, the lentivirus vector interfered by hsa_circ_0013561 was constructed and transfected. The cell proliferation was detected by CCK-8 method, EdU assay and plate cloning assay. The cell cycle and apoptosis were detected by flow cytometry, and the cell migration ability was detected by wound healing assay and Transwell assay. Western blotting examined the expression of apoptosis, Epithelial-Mesenchymal Transition (EMT)-associated proteins, and Janus Kinase/Signal Transductor and Activator of Transcription (JAK/STAT) signaling pathway-related proteins. Results The results showed that the expression of hsa_circ_0013561 in NPC samples was significantly upregulated and hsa_circ_0013561 localized in the cytoplasm. After down-regulating hsa_circ_0013561 expression, it significantly inhibited the proliferation and metastasis ability of NPC, inhibited EMT progression, and promoted apoptosis. Further studies showed that interference hsa_circ_0013561 significantly inhibited JAK2/STAT3 signaling pathway activation and induced the expression of apoptosis-related proteins. Conclusion In summary, we found that hsa_circ_0013561 is a pro-tumor circRNA in NPC, which can reduce the activation of JAK2/STAT3 pathway by knocking down hsa_circ_0013561, thereby slowing down the malignant progression of NPC.

Mechanism of Zhibai Dihuang decotion in treating postmenopausal osteoporosis / 药学学报

In this study, the ovarian surgery (ovariectomy, OVX) was used to establish the osteoporosis mice model of primary menstruation, in order to evaluate the protective effects and mechanisms of Zhibai Dihuang decotion on postmenopausal osteoporosis (PMOP). The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Jinan University (number: 20210315-03), in compliance with the Institutional Animal Care Guidelines. C57BL/6 mice were divided into five groups, including Sham group, OVX group, low (32 g·kg-1·day-1) and high dose (64 g·kg-1·day-1) of Zhibai Dihuang decotion groups, positive drug group (alendronate, 9.9 mg·kg-1·q3d). After modeling, mice were given medication intervention for 8 weeks, and then femoral and tibial tissues were taken to detect indicators such as bone microstructure, bone resorption, and oxidative stress. The experimental results showed that after Zhibai Dihuang decotion administration, the bone microstructure damage caused by OVX surgery was alleviated, and the relevant parameters bone mineral density (BMD), bone volume/total volume (BV/TV), trabecular number (Tb. N) and connectivity density (Conn. D) both significantly increased. At the same time, the number of TRAP positive osteoclasts decreased significantly, and the levels of proteins and genes related to osteoclast differentiation decreased, indicating that Zhibai Dihuang decoction could inhibit the increased activity of osteoclast caused by OVX. Afterwards, network pharmacology was used to construct the active compound action target network of Zhibai Dihuang decotion, and it was found that the target genes of its active ingredients were closely related to the oxidative stress pathway. Finally, the detection results of oxidative stress levels in bone tissues showed that after treatment with Zhibai Dihuang decotion, the levels of oxidative stress products 4-hydroxynonenal (4-HNE) and malondialdehyde (MDA) in bone tissues of mice significantly decreased, while the levels of antioxidant stress substance L-glutathione (GSH) increased. These above results indicated that Zhibai Dihuang decotion can regulate the level of oxidative stress in the body and inhibit osteoclast activity, which played a therapeutic role in PMOP, as well as provided theoretical basis for the prevention and treatment of PMOP with traditional Chinese medicine.

ConclusionThe mirror therapy with augmented reality could effectively improve attention of stroke patients in the short term.

Progress of researches on the role and mechanisms of non - coding RNA in Angiostrongylus cantonensis infection / 中国血吸虫病防治杂志

Angiostrongylus cantonensis is a food-borne zoonotic parasite, and human infection may cause eosinophilic meningitis. Non-coding RNAs (ncRNAs) may regulate physiological and pathological processes at multiple biological levels; however, there are few studies pertaining to the regulatory role of ncRNAs in A. cantonensis infection. Based on publications retrieved from PubMed, Wanfang Data and CNKI, the regulatory role of ncRNAs in A. cantonensis infections mainly includes immune responses, cell apoptosis and signaling transduction, and ncRNAs may serve as biomarkers for diagnosis of angiostrongyliasis. This review summarizes the main roles of ncRNAs in A. cantonensis infections and the underlying mechanisms, so as to provide insights into diagnosis and treatment of angiostrongyliasis.

Analysis of influencing factors for complications during percutaneous radiofrequency ablation of pulmonary tumor / 中国胸心血管外科临床杂志

@# Objective    To explore and analyze the related influencing factors for common intraoperative complications during CT-guided percutaneous radiofrequency ablation of pulmonary tumor. Methods    We retrospectively analyzed the clinical data of the patients who underwent CT-guided percutaneous radiofrequency ablation of pulmonary tumor in our hospital from December 2018 to December 2019, and analyzed the influencing factors for complications. Results    A total of 106 patients were enrolled. There were 58 (54.7%) males and 48 (45.3%) females aged 46-81 (68.05±8.05) years. All patients successfully completed the operation. The operation time was 47.67±16.47 min, and the hospital stay time was 2.45±1.35 d. The main intraoperative complications were pneumothorax (16.0%, 17/106) and intrapulmonary hemorrhage (22.6%, 24/106). Univariate analysis showed that the number of pleural punctures had an impact on the occurrence of pneumothorax (P=0.00). The length of the puncture path (P=0.00), ablation range (P=0.03) and ablation time (P=0.00) had an impact on the occurrence of intrapulmonary hemorrhage. Multivariate logistic regression analysis showed that the size of the lesion (OR=17.85, 95%CI 3.41-93.28, P=0.00) and the number of pleural punctures (OR=0.02, 95%CI 0.00-0.11, P=0.00) were independent influencing factors for the occurrence of pneumothorax. The length of the puncture path (OR=15.76, 95%CI 5.34-46.57, P=0.00) was the independent influencing factor for the occurrence of intrapulmonary hemorrhage. Conclusion    Percutaneous radiofrequency ablation of pulmonary tumor is safe and with a high success rate, but intraoperative complications are affected by many factors, so the surgeons should be proficient in operating skills to avoid complications.

OBJECTIVE To systematically evaluate the safety and effectiveness of intravenous human immunoglobulin （IVIG） combined with cyclophosphamide in the treatment of systemic lupus erythematosus （SLE）， and to provide an evidence-based basis for clinical medication. METHODS Retrieved from PubMed， Embase， Cochrane Library， CBM， CNKI and Wanfang database， randomized controlled trials （RCTs） about IVIG combined with cyclophosphamide versus cyclophosphamide alone based on glucocorticoids were collected. The quality of the included literature was evaluated with Cochrane 5.1.0 risk of bias assessment tool after literature screening and data extraction， and meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 13 RCTs were included， involving 842 patients. Meta-analysis showed that compared with cyclophosphamide alone， IVIG combined with cyclophosphamide improved the overall response rate of systemic lupus erythematosus [RR＝1.23， 95%CI（1.15， 1.32）， P＜0.000 01]， lowered the systemic lupus erythematosus disease activity index [MD＝－2.05， 95%CI（－2.51， －1.60）， P＜0.000 01]， relieved 24 h proteinuria [MD＝－1.29， 95%CI（－1.57， －1.01）， P＜0.000 01]， reduced the inflammatory factor MCP-4 [MD＝－28.04， 95%CI（－32.72， －23.37， P＜0.000 01）]， IL-4 [MD＝－1.66， 95%CI（－1.96， －1.36）， P＜0.000 01]， and boosted immune complement C3 [SMD＝0.74，95%CI（0.34，1.14）， P＝0.000 3] and complement C4 [SMD＝0.99，95%CI （0.31，1.67）， P＝0.004]； it had similar incidence of adverse drug reactions to cyclophosphamide therapy alone [RR＝0.81， 95%CI （0.57， 1.17）， P＝0.26]. CONCLUSIONS Compared with cyclophosphamide alone， IVIG combined with cyclophosphamide has a positive role in improving the overall response rate of treating SLE， improving clinical symptoms， reducing inflammatory factors， improving immune function， but the results should be interpreted with caution.

Progress of epidermal growth factor receptor-tyrosine kinase inhibitors in treatment of operable non-small cell lung cancer / 肿瘤研究与临床

Patients with operable non-small cell lung cancer (NSCLC) receiving neoadjuvant or adjuvant chemotherapy have a very limited improvement in 5-year survival rate. Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) have made a breakthrough in the treatment of EGFR-mutant advanced NSCLC, which shed light for the exploration of perioperative targeted therapy in NSCLC patients. Significant progress has been made in the research of targeted therapy of the first and third generation EGFR-TKI in perioperative patients. The availability of novel potent and less toxic targeted therapy has brought new treatments for the operable NSCLC. This article reviews the progress and existing problems of adjuvant and neoadjuvant targeted therapy in NSCLC harboring EGFR mutation.

The photos before and after treatment were compared and the mMASI of the patients' facial chloasma was compared. The scores were analyzed statistically, and the melasma were improved to varying degrees. Before treatment, the mMASI score was 5.4±3.22; 90 days later, the mMASI was 3.22±2.16, and the score decreased significantly ( t=5.9, P<0.05); after 120 days, mMASI score was 1.6±0.68, and the score decreased significantly ( t=7.55, P<0.05). Pigmentation occurred in one patient after treatment, and hypopigmentation after repair treatment; none of the patients had adverse reactions such as hypopigmentation. All the 80 patients had different degrees of improvement in pores and skin texture. Conclusions:The combination of micro-needling with lumin OX and brightline in the treatment of chloasma has a definite effect without obvious side effects. It provides a new method for the treatment of chloasma.

Application of scenario simulation teaching model of multimorbidity co-treatment in standardized training for general practice residents / 中华全科医师杂志

From February 1 to April 30, 2021, 48 general practice resident physicians in the First Affiliated Hospital of Naval Medical University were randomly divided into study group and control group with 24 in each group. The common comorbidities of the community-dwelling elderly, namely diabetes, diabetic retinopathy and osteoporosis were selected as teaching cases. The residents in control group received conventional teaching, while the scenario simulation teaching model of multicomorbity co-treatment was applied for the study group. The teaching effect, satisfaction and self-efficacy scores were compared between two groups. After training, the knowledge levels, the mastery of referral indicators and the performance of fundus ophthalmoscopy in the study group were significantly better than those in the control group ( t=2.27, 6.34, 4.09; P<0.05). They were (80.96±11.27) vs. (73.96±10.09), (10.33±2.41) vs. (6.38±1.88), (70.27±10.44) vs. (63.50±7.98), and students′ satisfaction and self-efficacy evaluation were higher than those of the observation group (all P<0.05). It is suggested that the simulation teaching of multi-disease co-treatment scenario is more beneficial than the traditional teaching to improve the comprehensive care ability of standardized training physicians in general practice for patients with chronic disease.

Significance of Sonoclot analysis for severity monitoring and evaluating perioperative liver transplantation recipients / 中华器官移植杂志

Objective:To explore the significance of coagulation and platelet function analysis (Sonoclot) in monitoring coagulation function, severity evaluation and blood transfusion indication of perioperative liver transplant (LT) recipients.Methods:A total of 95 perioperative LT recipients received Sonoclot, thromboelastography (TEG), routine coagulation panel, liver function panel, blood routine, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scoring and model for end-stage liver disease (MELD) scoring between January 2021 and October 2022.The correlation analysis of the above parameters was performed.According to the scores of APACHE Ⅱ and MELD, they were assigned into three groups of low-risk, medium-risk and high-risk.The levels of Sonoclot parameters in each group were compared.They were divided into two groups of transfusion (n=31) and non-transfusion (n=64) according to the necessity or non-necessity of transfusion..The risk factors for blood transfusion were examined by Logistic regression and receiver operating characteristic (ROC) curve.Results:Pearson's correlation analysis indicated that activated clotting time (ACT) value was correlated positively with the levels of prothrombin time (PT), prothrombin time ratio (PTR), international standard ratio (INR), R/K value, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactic dehydrogenase (LDH)( r=0.279 1, P=0.006 2; r=0.280 2, P=0.006 5; r=0.3, P=0.003 5; r=0.642 8, P<0.000 1; r=0.452 8, P<0.000 1; r=0.377 6, P=0.002; r=0.349 6, P=0.000 6; r=0.271 4, P=0.018 3) and yet negatively with the levels of platelet (PLT), MA, CI and α ( r=-0.339 1, P=0.000 8; r=-0.573 3, P<0.000 1; r=-0.656 3, P<0.000 1; r=-0.632 6, P<0.000 1); CR value was correlated positively with the levels of maximal amplitude (MA), coagulation index (CI), α and ALT ( r=0.466 8, P=0.000 6; r=0.482 7, P=0.000 4; r=0.514 8, P=0.000 1; r=0.229 2, P=0.027 1) and yet negatively with the level of R/K value ( r=-0.366 9, P=0.010 3; r=-0.356 9, P=0.011 0); platelet function (PF) value was correlated positively with the levels of PLT, MA, CI, α and alkaline phosphatase (ALP)( r=0.481 9, P<0.000 1; r=0.630 7, P<0.000 1; r=0.623 5, P<0.000 1; r=0.593 0, P<0.000 1; r=0.223 1, P=0.032 5) and yet negatively with the level of R/K value ( r=-0.421 5, P=0.002 8; r=-0.530 7, P<0.000 1). CR value was correlated negatively with APACHE Ⅱ score ( r=-0.212 3, P=0.038 9) while ACT value was correlated positively with MELD score ( r=0.244, P=0.04). ACT values spiked in low, middle and high-risk groups of APACHE Ⅱ and MELD scores while PF value declined gradually by grouping these recipients based upon scoring systems.CR values decreased merely in MELD score.Logistic regression analysis indicated that ACT was a risk factor for necessity of blood transfusion in perioperative LT recipients ( OR=1.010, 95% CI 1.000-1.019, P<0.05). The maximal area under the curve of ROC curve analysis plus ACT, hemoglobin (Hb) and hematocrit (Hct) was 0.896. Conclusions:Sonoclot parameters of perioperative LT recipients have some certain correlation with thromboelastographic and conventional coagulation parameters.Both may serve as a supplementary means.Associated with liver function parameters and liver scores, Sonoclot parameters are significant for early clinical evaluations.Sonoclot parameters plus Hb/Hct detection have some guiding significance for perioperative LT recipients with necessity for blood transfusion and blood products.
