Objective To evaluate the effects of Baihe Gujin Decoction on long-term survival in patients with non-small cell lung cancer(NSCLC)receiving radiotherapy(RT)in the real world.Methods Retrospective data from patients with NSCLC receiving RT in the Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine(TCM)and data from patients in the Surveillance,Epidemiology and End Results(SEER)database were collected and grouped as the TCM+conventional Western medicine(CWM)cohort and CWM cohort,respectively.Propensity score matching(PSM)was used to balance confounders between groups.Kaplan-Meier curve and Cox regression model were used to estimate the effects of Baihe Gujin Decoction on survival outcomes of patients receiving RT.Results Totally 190 samples with a balance between groups were obtained using PSM.Overall survival(OS)analysis showed that the TCM+CWM cohort had significantly longer OS than the CWM cohort(P=0.004).Subgroup analysis showed that the Baihe Gujin Decoction was more advantageous in the characteristic population of age≥65 years(P=0.027),male(P=0.010),T3-T4 stage(P<0.001),N2-N3 stage(P=0.026),M1 stage(P<0.001),not receiving chemotherapy(P<0.001),and not undergoing surgery(P<0.001).Multivariate Cox regression confirmed that treatment group(P=0.003),T(P=0.003)and M stages(P=0.002)may be the independent prognostic factors for OS of NSCLC patients treated with RT.Conclusion Baihe Gujin Decoction probably can improve the long-term prognosis in NSCLC patients treatment with RT.

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To identify the clinical characteristics and adverse events of patients with giant cell arteritis (GCA).Methods:Patients who were hospitalized and diagnosed with GCA in Zhongshan Hospital, Fudan University, from December 2009 to November 2020 were enrolled into a retrospective study analysis. Baseline data and follow-up data were collected. Adverse events were defined as one of the following events: relapses, ischemic complications and death. Patients with adverse events were analyzed in clinical features and risk factors by univariate and multivariate analysis. Associations with adverse events were assessed using ROC curve and survival curves.Results:A total of 69 patients with GCA were included in this study, with the male: female ratio of 1∶1.03. Fatigue and headache were common symptoms. Finally, 61 patients were followed up at the end of May in 2021. Over the mean follow-up time of (35±20) months, adverse events occurred in 16 cases (26.2%). Patients with adverse events had significantly lower levels of platelet and globulin at baseline than those without adverse events [(325±142)×10 9/L vs (238±112)×10 9/L, t=2.22, P=0.030]; [(31±6) g/L vs (26±6) g/L, t=2.74, P=0.008]. Red cell volume distribution width-coefficient of variation (RDW-CV) was considered an independent risk factor for adverse events [ OR (95% CI)=0.32 (0.14,0.74), P=0.008]. Further, patients especially with RDW-CV<14.75% were prone to have adverse events, which occurred in 2.6%, 20.5%, 25.6%, 33.3%, 41.00% in 1, 2, 3, 5, 10 years. Its risk increased significantly after 2 years ( P=0.042, P=0.021, P=0.002, P=0.001). The incidence of adverse events was much higher in patients with RDW-CV<14.75%(95% CI=0.002). Conclusion:Adverse events are common in patients with GCA. RDW-CV is an independent risk factor for having adverse events. Low level of RDW-CV predicts an increased risk of adverse events by the following years.

Objective To investigate the potential risk factors for mild cognitive impairment (MCI) in the elderly population in the community, and to provide a basis for the primary prevention of MCI. Methods A cross-sectional study of elderly population in communities of Shanghai, China was conducted. A total of 368 subjects including both males and females, aged 65-80 years old, were selected to complete the mini-mental state examination (MMSE), basic information questionnaires, and physical examinations. Logistic regression analysis was used to analyze the potential risk factors of MCI. Results Of the 368 subjects participating in the study, 53 were found to have MCI and the prevalence rate was 14.4%. Univariate analysis found that older age, low education, no folic acid supplementation, stroke, osteoporosis and hyperlipidemia were risk factors of MCI. Multiple logistic regression analysis showed that advanced age [OR=1.146 (95%CI: 1.052-1.249)] and osteoporosis [OR=2.371 (95%CI: 1.042-5.396)] were the independent risk factors for MCI, while higher education [OR=0.073 (95%CI: 0.011-0.478)] was a protective factor. Age influenced all the aspects of MMSE scores (all P values <0.05). In addition, the analysis of the results suggested that subjects with regular folic acid supplementation got higher MMSE scores, especially in the aspect of language and praxis (P=0.002). On the contrary, patients with osteoporosis had lower attention and computing power scores (P=0.022). Conclusion The prevalence of MCI increased with age. Low education and osteoporosis may be the independent risk factors for MCI in the elderly population. Although no association was observed between folic acid supplementation and MCI, folic acid supplementation could improve the performance of language and praxis.

Objective To investigate serum lipid profiles in newly diagnosed patients with polycystic ovary syndrome (PCOS) using lipidomics and correlate these features with hyperinsulinemia and hyperandrogenism associated with PCOS and obesity. Methods 32 newly-diagnosed PCOS women and 34 controls were enrolled and divided into obese and lean subgroups according to the body mass index (BMI). Anthropometric, biochemical, and hormonal parameters were collected. Serum lipid profiles including phospholipids, free fatty acids (FFAs), and bioactive lipids were analyzed using GC-MS and LC-MS. Results PCOS patients, in particular, the obese ones with fatty liver, have abnormal phosphatidylcholine (PC)/lysophospholipid (LPC) metabolism. PC was increased (16∶0, 18∶0, 18∶1, 18∶2, and 20∶4), while LPC was decreased (16∶0, 18∶0, and 18∶1; all P<0.05). Serum polyunsaturated fatty acids (PUFAs), were decreased significantly, and the long chain saturated fatty acid was increased. We also found that insulin stimulated the metabolism of PUFAs, but the androgen inhibits the metabolism of PUFAs by measuring their metabolites. Conclusion PCOS patients have metabolic disorders of phospholipids and PUFAs. Insulin stimulated while androgen inhibited PUFAs metabolism.

Human height, a complex trait with over 80% heritability, is determined by genetic and environment factors. Currently, a certain amount of specific variants about human height have been found, especially with the widely used of genome-wide association studies (GWAS) in genetics research, making it a great progress for the discovering of height associated genes. However, single nucleotide polymorphisms (SNPs) found by GWAS can only explain a minority of the heritable. This article reviews the progress of GWAS about height associated genes and missing heritability domestic and overseas.

Objective To investigate and characterize the serum metabolite profile of patients with rheumatoid arthritis (RA),a common autoimmune disease,which will be of help for early diagnosis in clinic.Methods Serum specimens from 26 patients with RA and 19 age-matched healthy volunteers were collected from the First Affiliated Hospital of Hunan University of Chinese Medicine from January through April 2015.Samples were detected on the gas chromatography-mass spectrometry (GC-MS),and serum metabolites were identified by the chemometric methods.Discriminative model of RA and healthy volunteers was established using partial least squares-linear discriminant analysis (PLS-LDA),and furthermore the established model was evaluated with double cross validation (DCV) for predicting ability.Finally,differential metabolites with clinical diagnostic potential were screened out by using subwindow permutation analysis (SPA).Results The established PLS-LDA discriminative model identified 48 metabolites.The total accuracy of the model approached 97.73％,in which the accuracy of the model for predicting RA and healthy volunteers was 96.15％ and 100％,respectively.Our studies screened out 3-hydroxy butyric acid,phosphoric acid,isoleucine,mannose and hexadecanoic acid with clinical diagnostic potential based on the SPA.Conclusions Metabolomics with the application of GC-MS combined with the PLS-LDA method can distinguish patients with RA and healthy volunteers,and can aid in potential early diagnosis of RA.

Objective To analyze the perioperative risk factors of postoperative complications after posterior lumbar fusion operation.Methods The clinical data of 654 patients with posterior lumbar fusion during 2010 and 2014 were retrospectively analyzed.Using x2 test and one-way ANOVA,the predicted risk factors were screened for further Logistic regression.Results The total complication rate was 11.6％ among all 654 patients.The major complications included cardiac infarction,deep infection,sepsis,neurological impairment,and secondary operation.And the minor complications included wound dehiscence,urinary tract infection,pulmonary infection,gastrointestinal bleeding,CSF leakage and others.According to x2 test and one-way ANOVA,renal function insufficiency,preoperative neurological injury,ASA higher than Ⅲ level,intraoperative blood loss,long operation length,and usage of autogenous bone were screened as risk factors of complications.Renal function insufficiency,preoperative neurological injury,intraoperative blood loss,and long operation length were screened as risk factors of minor complications.And male,renal function insufficiency,preoperative neurological injury,intervertebral fusion,and posteriolateral fusion were screened as risk factors of major complications.However,according to Logistic regression,the independent risk factor of complications were preoperative neurological injury and long operation length;independent risk factors of minor complications were renal function insufficiency,preoperative neurological injury and long operation length;and independent risk factor of major complications was preoperative neurological injury.Conclusion Preoperative neurological injury,renal function insufficiency and long operation length are proved to be the risk factors of postoperative complication in lumbar fusion surgery.

Objective To observe the morphological changes of carotid artery wall by ultrasonography in patients with Takayasu arteritis,and to evaluate the diagnostic value of contrast-enhanced ultrasonography for active Takayasu arteritis.Methods High-frequency ultrasound technique was used to analyze the morphological changes of the carotid artery in 40 patients.NIH score was used as the gold standard and the complete clinical data and acute phase reactors were recorded.T test,Chi-square test,sensitivity and specificity were calculated for statistical analysis.Results The thickness of carotid artery wall in active group was much more thickened than the non-active group [(2.2±0.6) mm vs (1.8±0.5) mm,t=-2.142,P＜0.05].The CDD [(0.89±0.06) in active group vs (0.95±0.03) in non-active group,t=3.683,P＜0.01] and RDD [(0.17±0.06 in active group vs (0.09±0.05) in non-active group,t=-4.020,P＜0.01] were significantly different between the two groups.The distribution of neovascularization in the carotid artery wall of the active group was more diffuse in the central part of the wall.The sensitivity and specificity of contrast-enhanced ultrasonography to diagnose the active of Takayasu arteritis were 72.7％ and 87.5％ respectively,and the positive predictive value and the negative predictive value were 80.0％ and 82.4％ respectively.Conclusion Contrast-enhanced ultrasonography can be used as an effective way to assess the disease activity of TA patients.
