BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Hepatocellular carcinoma （HCC） is the sixth most common cancer in the world. In recent years， the clinical early diagnosis and treatment protocols of HCC have been improved， whereas the prognosis of patients is still not satisfactory， which is due to the fact that the mechanism of HCC development has not been fully elucidated. Therefore， it is of great significance to explore the molecular mechanisms and key regulatory links of hepatocellular carcinoma development to further improve the diagnosis and treatment of HCC in China. Epigenetics has become a research hotspot because of its reversibility and easy regulation. According to relevant studies， HCC involves the accumulation of multiple genetic and epigenetic changes during the initiation， promotion， and progression stages. HCC is categorized as infantile malnutrition with accumulation， hypochondriac pain， tympan ites， and abdominal mass in traditional Chinese medicine （TCM）. In the treatment of HCC， TCM with low toxicity， multi-targets， and multi-mechanisms can inhibit tumor growth， alleviate the clinical symptoms， and enhance the quality of life of the patients. Chinese medicines and their active ingredients exert anti-HCC effects through epigenetic regulation of DNA methylation， histone modification， and non-coding RNA. Abnormal gene expression due to epigenetic regulation disorders is involved in all stages of HCC development. There are few studies on epigenetic regulation in TCM treatment of HCC， and there is still much room for development in basic and clinical trials. This paper reviews the mechanism of epigenetic regulation in HCC and summarizes the experimental results of TCM research on the related mechanism， with a view to providing a theoretical basis for future research on the mechanism of HCC development and clinical diagnosis and treatment of hepatocellular carcinoma with TCM.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

BACKGROUND: Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment. METHODS: This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR. RESULTS: A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2 months by IRC and 13.4 months by investigator assessment; the median PFS was 18.6 months and 15.3 months, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities. CONCLUSION: Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.

OBJECTIVE: To investigate the correlation between degenerative lumbar scoliosis and osteoporosis in adults. METHODS: From March 2012 to June 2016, the clinical data of 53 patients with degenerative lumbar scoliosis were retrospectively analyzed for a correlation study between degenerative lumbar scoliosis and osteoporosis. Fifty-three patients with degenerative lumbar scoliosis were selected as observation group and another 53 inpatients without lumbar scoliosis as control group. There were 11 males and 42 females with an average age of 69 years (range 63 to 76 years) old in observation group. And in control group, there were 16 males and 37 females with an average age of 68.5 years (range 59 to 74 years) old, including lumbar disc herniation in 33 cases, lumbar spinal stenosis in 13 cases, spondylolisthesis in 7 cases. The 53 patients with degenerative lumbar scoliosis were confirmed by X-ray and MRI, their Cobb angle of lumbar scoliosis was measured. Dual energy X-ray absorptiometry was used to measure the bone mineral density, the T values of L₂-L₄ segments, femoral neck, Ward triangle and femoral trochanter were recorded. Linear regression analysis was used to analyze the correlation between osteoporosis and degenerative lumbar scoliosis. RESULTS: There were significant differences in the bone mineral density T values between two groups (<0.05). Bone mineral density T value in patients with lumbar scoliosis were significantly higher than that in the patients with no lumbar scoliosis (<0.05), (-2.56±0.65 vs -1.39±0.77). The T values of L₂-L₄ segments, femoral neck, Ward triangle and femoral trochanter had no remarkable correlation with Cobb's angles. CONCLUSIONS Osteoporosis is a risk factor for degenerative scoliosis, but the severity of osteoporosis and degree of scoliosis has no obvious correlation.

Objective To explore the genetic background and structure of Urumqi Mongolians, the previously developed 39-AIM-InDels panel for ancestry inference was utilized in the present study. Methods The blood samples of 145 unrelated healthy Urumqi Mongolian individuals were collected and genotyped. The compositions of ancestry information of Urumqi Mongolians were studied with 17 different populations from three continents （East Asia, Europe and Africa） as reference populations. Then, multiple population genetics and bioinformatics analysis methods were applied, the Fst and DA values between matched populations were compared and analyzed, PCA analysis was performed and a phylogenetic tree was constructed. The proportions of ancestry information components of Urumqi Mongolians were analyzed with Structure software, etc. Results The ancestry information components of Urumqi Mongolian group in different intercontinental populations accounted for 89%, 7%, and 3% of East Asian, European, and African populations, respectively. Compared with other intercontinental populations, Urumqi Mongolian group and East Asian populations have lower Fst and DA values, and they were in the same cluster in PCA analysis as well. In a phylogenetic tree, the Urumqi Mongolian group was in the same branch as East Asian populations. Conclusion Urumqi Mongolian group had relatively close genetic relationships with East Asian populations, and the proportion of its East Asian ancestry was about 89%.

OBJECTIVETo evaluate the role of enhanced recovery after surgery in treating cervical spondylotic myelopathy.

METHODSThe clinical data of 55 patients with cervical spondylotic myelopathy underwent surgical treatment from January 2012 to December 2015 were retrospectively analyzed. There were 30 males and 25 females, age from 36 to 71 years old with an average of (45.2±3.2) years, course of disease was for 1 to 12 months with an average of (4.5±1.8) months. The concept of enhanced recovery after surgery and perioperative management were applied to surgical treatment in 35 patients (study group), and the same period, 20 patients without strategy of enhanced recovery after surgery (control group). Thirty-eight patients were treated by anterior cervical discectomy decompression and fixation(ACDF), 17 patients were treated by posterior single-open door laminoplasty decompression. The activity time out of bed, hospitalization days after surgery were compared between two groups. Japanese Orthopaedic Association (JOA) score and visual analogue score(VAS) before operation, after operation at 1, 7, 30 days and 6, 12 months was respectively used to evaluate the neurological function and pain.

RESULTSAll the patients were followed up for 12 to 18 months with an average of (14.3±1.5) months. There was no significant difference in age, gender, surgical methods, preoperative VAS, JOA score between two groups (>0.05). The activity time out of bed was 3 to 8 h with an average of (5.54±1.54) h, postoperative hospitalization time was 3 to12 d with an average of (5.62±1.59) d in study group, while in control group, the activity time out of bed was 24 to 48 h with an average of (18.80±4.78) h, and postoperative hospitalization time was 7 to 17 d with an average of (9.85±1.94) d; there was significant difference between two groups (<0.01). There was significant difference in VAS and JOA scores between two groups at 1, 7, 30 d after operation (<0.01), and there was no significant difference at 6, 12 months after operation(>0.05). There were no neurologic function deterioration, hematoma, wound infection, internal fixation loosening and other complications in study group during hospitalization and following-up;there were 2 cases of superficial wound infection in the control group, who healed by dressing change for 2 weeks;there was no significant difference between two groups(>0.05).

CONCLUSIONSThe strategy of enhanced recovery after surgery in treating cervical spondylotic myelopathy can promote the early recovery, shorten the length of stay and improve the patient's degree of satisfaction.

OBJECTIVETo determine whether additional Chinese medicine (CM) could prolong survival and improve the quality of life (QOL) in patients with advanced non-small cell lung cancer (NSCLC) compared with Western medicine (WM) alone.

METHODSThis was a multicenter, prospective cohort study. A total of 474 hospitalized patients with stage III-IV NSCLC were recruited and divided into 2 groups. Patients in the WM group received radiotherapy, chemotherapy, and optimal supportive therapy according to the National Comprehensive Cancer Network (NCCN) guidelines. In the integrative medicine (IM) group, individualized CM (Chinese patent medicines and injections) and WM were administered. The primary end point was overall survival, and the secondary end points were time to disease progression, adverse events, and QOL. Follow-up clinical examinations and chest radiography were performed every 2 months.

RESULTSThe median survival was 16.60 months in the IM group and 13.13 months in the WM group (P<0.01). The incidences of loss of appetite, nausea, and vomiting in the IM group were significantly lower than those in the WM group (P<0.05). The QOL based on Functional Assessment of Cancer Therapy-Lung in the IM group was markedly higher than that in the WM group at the fourth course (P<0.05).

CONCLUSIONSAdditional CM may prolong survival and improve the QOL patients with NSCLC. The adverse effects of radio- and chemotherapy may be attenuated as CM is used in combination with conventional treatments.

Although 5-aminolevulinic acid (5-ALA)-mediated photodynamic therapy (PDT) has been demonstrated to be a novel and effective therapeutic modality for some human malignancies, its effect and mechanism on glioma are still controversial. Previous studies have reported that 5-ALA-PDT induced necrosis of C6 rat glioma cells in vitro. The aim of this study was to further investigate the effect and mechanism of 5-ALA-PDT on C6 gliomas implanted in rats in vivo. Twenty-four rats bearing similar size of subcutaneously implanted C6 rat glioma were randomly divided into 3 groups: receiving 5-ALA-PDT (group A), laser irradiation (group B), and mock procedures but without any treatment (group C), respectively. The growth, histology, microvessel density (MVD), and apoptosis of the grafts in each group were determined after the treatments. As compared with groups B and C, the volume of tumor grafts was significantly reduced (P<0.05), MVD was significantly decreased (P<0.001), and the cellular necrosis was obviously increased in group A. There was no significant difference in apoptosis among the three groups. The in vivo studies confirmed that 5-ALA-PDT may be an effective treatment for gliomas by inhibiting the tumor growth. The mechanism underlying may involve increasing the cellular necrosis but not inducing the cellular apoptosis, which may result from the destruction of the tumor microvessels.
