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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To analyze the chemical constituents in the water extract of Bupleuri Radix and investigate the active ingredients of Bupleuri Radix for the treatment of depression.Methods The chemical constituents in the water extract of Bupleuri Radix were identified by Ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS).CORT-induced poorly differentiated PC12 depression cell model was launched,and PC12 cells were pretreated with monomeric compounds from Bupleuri Radix for 24 h.The cell viability and LDH release rate were measured by CCK-8 assy kit and LDH assay kit,respectively.Results A total of 53 compounds were identified in the water extract of Bupleuri Radix,mainly including type Ⅰ,type Ⅱ and type Ⅲsaikosaponins.Among them,saikosaponin A,saikosaponin B2,saikosaponin C,saikosaponin E,saikosaponin F and 6″-acetyl saikosaponin A contributed the most to the metabolite profile of Bupleuri Radix,and could improve the viability of CORT-induced PC12 cells(P<0.05,P<0.01).Furthermore,saikosaponin A,saikosaponin B2,saikosaponin C,saikosaponin E and saikosaponin F could decrease the LDH release rate of CORT-induced PC12 cells(P<0.05,P<0.01).Conclusion The major anti-depression active ingredients in Bupleuri Radix may be Saikosaponin A,saikosaponin B2,saikosaponin C,saikosaponin E and saikosaponin F,which lays a foundation for the research of the quality control and pharmacodynamic material basis of Bupleuri Radix.

OBJECTIVE: To analyze the long-term trends of the changes in the equity of China's health workforce allocation to provide a reference for the more balanced and orderly development of China's health system. METHODS: The Gini coefficient was used to evaluate the degree of equity in the allocation of health workforce between regions, and the Gini coefficients for the allocation of doctors and nurses based on population and regional gross domestic product (GDP) distribution were calculated respectively. RESULTS: In 2019, the number of licensed (assistant) physicians per 1 000 population in China was 2.77, and the number of registered nurses per 1 000 population was 3.18. The Gini coefficient for the distribution of licensed (assistant) physicians by population was 0.141 in 2002, decreasing to 0.081 by 2014 and then remained stable. The Gini coefficient for the distribution of registered nurses by population was 0.164 in 2002 and decreased to 0.066 in 2018. The Gini coefficient for the distribution of licensed (assistant) physicians by GDP was 0.236 in 2002, decreased to 0.169 in 2013, then increased to 0.183 and remained stable. The Gini coefficient for the distribution of registered nurses by GDP was 0.206 in 2002, decreased to 0.150 in 2013, and then increased each year to 0.180 in 2019. The equity of the allocation of registered nurses by population was worse than the equity of the allocation of licensed (assistant) physicians in 2002, and in 2016, for the first time, exceeded that of licensed (assistant) physicians. CONCLUSION Equity in the allocation of health workforce across China has improved, but the improvement in equity between regions has hit a bottleneck, with health workforce allocation in the western regions still relatively scarce. Although nursing workforce allocation equity caught up with licensed (assistant) physicians, the number of licensed (assistant) physicians is close to that of developed western countries, while there is a large gap in registered nurses. It is recommended that the relevant authorities make good long-term planning for health workforce, further increase the policy for the introduction of health workforce in the western region, and increase the supply of healthcare services in the western region with the help of digital transformation of healthcare and internet healthcare. At the same time, they should further increase investment in resources for higher nursing education and actively plan to cope with the ageing population.

OBJECTIVE: To evaluate the feasibility and effectiveness of the totally extraperitoneal renal autotransplantation with boari flap-pelvis anastomosis in the treatment of upper urinary tract urothelial carcinoma (UTUC), and to review the experience of renal autotransplantation for UTUC treatment. METHODS: One case of applying the totally extraperitoneal renal autotransplantation with boari flap-pelvis anastomosis to the UTUC treatment was reported, and related literature was reviewed. The patient was a sixty-four-year old man who received right radical nephroureterectomy for right ureteral carcinoma 1 year before and diagnosed as left ureteral carcinoma(G2, high grade) this time. In order to preserve his renal function and avoid the shortness of common kidney-sparing surgery, a totally extraperitoneal procedure, including retroperitoneoscopic nephrectomy, ureterectomy, renal autotransplantation and Boari flap-pelvis anastomosis, was performed to the patient. RESULTS: The operation was completed successfully without perioperative complications. The renal function recovered to preoperative level within 1 week. No deterioration of renal function during the follow-up and no tumor recurrence was observed under cystoscopy at the 3-month postoperative consult. CONCLUSION The totally extraperitoneal renal autotransplantation with Boari flap-pelvis anastomosis is a feasible and effective treatment for UTUC. The innovative procedure has several advantages compared to the former ones. The extraperitoneal procedure results in significantly less pain, shorter hospital stay, decreased overall time to recovery and lower bowel complications risk without warm ischemia time extension. Meanwhile, the Boari flap-pelvis anastomosis simplifies the follow -up protocols and creates an easy route for cystoscopy and topical therapy. From the systematic clinical analysis, as well as the related literature review, it's been concluded that the renal autotransplantation can be a reasonable option for the patients who have UTUC in solitary kidney or have bilateral UTUC. This type of treatment possesses advantages of preservation of renal function and total resection of malignant lesions. But long-term data and large cohort study on renal function or tumor recurrence are still absent which will be necessary to confirm the advantages of this approach.

AIM:To observe the effect of interleukin-27 (IL-27) on the pathological changes and the expres-sion and activation of NOD-like receptor protein 3 (NLRP3) inflammasome in the colonic tissues of the mice with dextran sodium sulfate (DSS)-induced experimental colitis. METHODS:Male C57BL/6 mice (n=48) were randomly divided into control group (given unrestricted diet), DSS group (drinking 3% DSS solution), IL-27 (500 ng) group and IL-27 (1 &mu;g) group (intraperitoneal injection of 500 ng and 1 &mu;g IL-27 on the basis of drinking DSS solution, respectively). After treatment for 12 d, intestinal inflammation in the mice was evaluated, the pathological changes of the colonic tissues were observed by HE staining, and the disease activity index ( DAI) score and histological index ( HI) score were calculated. The colonic tissues were collected for immunohistochemistry, qPCR and Western blot detections. The serum was prepared for ELISA. RESULTS:Compared with control group, the DAI score and HI score in model group indicated that the colo-nic inflammation was more obvious (P<0.05), the mRNA expression of NLRP3 and IL-1β was increased, the protein levels of NLRP3 and cleaved caspase-1 were elevated, and the releases of IL-1β and IL-18 in the serum were also increased (P<0.05). Compared with DSS group, the DAI score and HI score in IL-27 (1 &mu;g) group indicated that the colonic in-flammation was obviously attenuated, the mRNA expression of NLRP3 and IL-1β was decreased, the protein levels of NLRP3 and cleaved caspase-1 were suppressed, and the releases of IL-1β 和 IL-18 in the serum were also decreased (P<0.05). No difference of the above indexes between DSS group and IL-27 (500 ng) group was observed except the de-creases in the releases of IL-1β and IL-18 in the serum in IL-27 (500 ng) group. CONCLUSION:IL-27 alleviates the inflammation in DSS-induced colitis mice and inhibits the expression and activation of NLRP3 inflammasome.

Objective Head and neck cancer radiotherapy patients often appear a series of oral complications including mucositis, xerostomia, pain, dysphagia.The purpose of this study was to investigate whether personalization customized positioning oral stent was able to push normal tissue off the high dose target area and maintain accurate repeatable stable positions, thus protecting the normal tissue during radiotherapy of the nasopharyngeal carcinoma patients.Methods 15 newly diagnosed nasopharyngeal carcinoma patients were collected from March to August 2016 in Department of Radiation Oncology, Nanjing General Hospital of Nanjing Military Region and randomly divided into trial group and control group.Two groups of patients were treated with intensity modulated radiation therapy (IMRT).Trial group patients wear personalization customized oral positioning stents during radiotherapy while the control group did not wear.After radiotherapy, we compared the exposure doses of clinical target area(CTV) and normal oral tissue in two groups.ResultsThe left parotid gland radiotherapy doses of the trail group and the control group were 2223.557±294.549 cGy and 2900.563±374.660 cGy, the difference was statistically significant(t=3.847, P=0.002);the right parotid gland radiotherapy doses of the trail group and control group were 2284.957±256.673 cGy and 2994.670±339.264 cGy, the difference was statistically significant(t=4.512, P=0.001).The mean exposure doses of CTV in two groups were no statistically significant difference (6142.829±135.986 cGy vs 173.306±6221.825 cGy, t=0.971, P=0.349.Conclusion During the intensity modulated radiation therapy, patients with personalization customized oral positioning stents can keep the mandible in a precise repeatable stable position.And it can reduce the exposure dose of bilateral parotid without affect the radiotherapy effect of the clinical target area.

BACKGROUNDHalo nevus (HN) has been shown to be associated with vitiligo, but no standard signs are currently available to identify HN patients at risk of vitiligo, and the relevant data obtained in previous studies are somewhat conflicting. This study aimed to identify factors affecting the presence of vitiligo in HN patients.

METHODSWe performed a retrospective study on consecutive patients with HN at the First Affiliated Hospital of Sun Yat-sen University between January 2011 and December 2016. Detailed demographic and clinical data were collected to identify the factors associated with the presence of vitiligo in this cohort of patients using uni- and multi-variate logistic regression analyses.

RESULTSA total of 212 HN patients were included, 101 of whom had vitiligo-associated HN (HNV). Univariate analysis indicated that a personal history of thyroid diseases was positively associated with HNV (odds ratio [OR] = 10.761, P = 0.025), while the onset age of HN was negatively associated with HNV (OR = 0.537, P = 0.026). Multivariate analysis demonstrated that the Koebner phenomenon (KP; OR = 10.632, P < 0.0001), multiple HN (OR = 3.918, P < 0.0001), and a familial history of vitiligo (OR = 3.222, P = 0.014) were independent factors associated with HNV.

CONCLUSIONSHN without vitiligo has clinical features distinct from HN associated with vitiligo. HN patients with KP, multiple lesions, or familial history of vitiligo are more likely to develop vitiligo and therefore should be monitored for clinical signs of such accompanied conditions.

Objective To analyze the correlation between the condition of patients with spastic cerebral palsy, including age, sex, weight, number of the affected limb and gross motor function and their rehabilitation effect after selective posterior rhizotomy (SPR), and to explore the possible factors that contribute to the rehabilitation of motor function in patients with spastic cerebral palsy.Methods Totally 53 patients with spastic cerebral palsy admitted in the Departments of Orthopedics and Rehabilitation of Dongzhimen Hospital, Beijing University of Chinese Medicine were selected from October 2013 to October 2015. The patients received uniform and standard rehabilitation treatment after SPR, and their motor function was evaluated with the Gross Motor Function Measure (GMFM) before the surgery and six months after the surgery. Then the correlation between the patients' age, sex, weight, GMFM score before treatment and number of the affected limb and the difference in their motor function before and after treatment was analyzed.Results The patients' score in improved motor function was negatively correlated with their age (r=-0.30,P<0.01) and weight (r=-0.30, P<0.01), and not correlated with their sex (r=0.00,P=1.00), motor function before treatment (r=-0.20,P>0.05) or number of the affected limb (r=-0.20,P>0.05).Conclusions For patients aged between 3 and 25, the earlier they are treated, the better the effect is. The patients should control their weight properly so as not to affect the rehabilitation effect after surgery. The patients' sex, motor function before treatment and number of the affected limb cannot help to predict the recovery of their motor function after surgery. Researchers will continue to conduct large-sample and multi-factor studies in order to verify the current conclusions and analyze the influencing factors of SPR effect in a more comprehensive way.
