As a common clinical disease, fracture is often accompanied by pain, swelling, bleeding as well as other symptoms and has a high disability rate, even threatening life, seriously endangering patients' physical and psychological health and quality of life. Medical practitioners take many strategies for the treatment of fracture healing, including Traditional Chinese Medicine (TCM). In the early stage of fracture healing, the local fracture is often in a state of hypoxia, accompanied by the expression of hypoxia inducible factor-1α (HIF-1α), which is beneficial to wound healing. Through literature mining, we thought that hypoxia, HIF-1α and downstream factors affected the mechanism of fracture healing, as well as dominated this process. Therefore, we reviewed the local characteristics and related signaling pathways involved in the fracture healing process and summarized the intervention of TCM on these mechanisms, in order to inspirit the new strategy for fracture healing, as well as elaborate on the possible principles of TCM in treating fractures based on the HIF molecular mechanism.

ObjectiveTo observe the clinical efficacy and mechanism of Tongnao Yizhi Formula （通脑益智方， TYF） in treating vascular cognitive impairment no dementia （VCIND） with spleen and kidney depletion， phlegm and stasis obstructing collaterals syndrome. MethodsNinety-two VCIND patients with spleen and kidney depletion， phlegm and stasis obstructing collaterals syndrome were randomly divided into control group （42 cases） and treatment group （52 cases）. Both groups received routine basic treatment. The control group was given donapezil hydrochloride capsules orally， 5 mg each time， once at night， while the treatment group was given TYF orally， 1 dose per day. Both groups were treated continuously for 3 months. The scores of Mini-Mental State Examination （MMSE）， Vascular Dementia Assessment Scale-Cognitive Subscale （VaDAS-Cog）， Activity of Daily Living Scale （ADL）， and TCM syndrome scores （the primary symptoms such as sluggish thinking， forgetfulness， temperament changes， and language confusion， and secondary symptoms such as weakness of waist and knees， dizziness and headache， occasional tinnitus， fatigue， heaviness of limbs， insomnia and irritability， poor appetite and abdominal distension， numbness of face） were observed before and after treatment in both groups. The changes in gut microflora diversity and flora abundance structure as well as fecal short-chain fatty acids （SCFAs） levels including acetic acid， propionic acid， butyric acid， isobutyric acid， isovaleric acid， valeric acid， and caproic acid were compared between groups. The feces of 20 healthy subjects in the same period were included as reference. Safety was evaluated during the study. ResultsAfter treatment， both groups exhibited significant increases in MMSE scores and decreases in VaDAS-cog scores （P＜0.05 or P＜0.01）， and ADL scores in the treatment group significantly increased （P＜0.05）. Scores of symptoms including sluggish thinking， forgetfulness， temperament change， language confusion， heaviness of limbs， insomnia， irritability， poor appetite， abdominal distension， and facial numbness as well as the total score significantly decreased in both groups after treatment （P＜0.05 or P＜0.01）. When compared between groups， the treatment group showed substantial reductions in scores of weakness of waist and knees， tinnitus， fatigue， heaviness of limbs， insomnia， irritability， loss of appetite and abdominal distension （P＜0.05 or P＜0.01）. The gut microflora diversity analysis showed that the Shannon index of the treatment group significantly increased after treatment （P＜0.05）.PCoA analysis and ANOSIM test indicated significant differences between groups， suggesting changes in microflora species （P＜0.01）. After treatment， the relative abundance of Bacteroidetes and Fusobacteria in the treatment group increased， while the relative abundance of Actinobacteria， Verrucomicrobia and Cyanobacteria decreased （P＜0.05）； the relative abundance of Faecalibacterium prausnitzii， Bifidobacterium， Lactobacillus， and Ruminococcus increased significantly （P＜0.05）. Compared to the the gut microflora species diversity of the healthy people， it is indicated that the gut microflora structure in the treatment group was close to that of the healthy people， while there was no such trend in the control group. In the treatment group， acetic acid， propionic acid， and butyric acid in the treatment group were all higher after treatment （P＜0.05 or P＜0.01）. ConclusionsTYF can improve the cognitive ability and quality of life of VCIND patients with spleen and kidney depletion， phlegm and stasis obstructing collaterals syndrome， and this improvement may be related to regulating intestinal microecology.

Objective·To analyze the clinical and genetic characteristics of Chinese pediatric patients with Barth syndrome(BTHS)and provide data to support the prevention and treatment of BTHS.Methods·Eighteen pediatric patients diagnosed with BTHS at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,from January 2010 to November 2023,were included.Clinical data(age,birth weight,family history,electrocardiogram,echocardiogram,urine tandem mass spectrometry,complete blood count,blood biochemistry,and genetic test results)were collected to analyze the clinical characteristics,genetic findings,and prognoses of the patients.Results·The study included 18 male patients with BTHS(including 2 monozygotic twins),consisting of one Yi ethnic and 17 Han Chinese patients.The median age at diagnosis was 3.0(1.0,5.6)months.Fifteen patients experienced decreased cardiac function at disease onset,with a left ventricular ejection fraction(LVEF)below 50%.Dilated cardiomyopathy(DCM)was observed in 15 patients,left ventricular non-compaction(LVNC)in 12 patients,and myocardial hypertrophy in 9 patients.During the diagnosis and follow-up,QTc interval prolongation occurred in 9 patients,ventricular arrhythmias in 2 patients,neutropenia in 9 patients,and monocytosis in 10 patients.Urine tandem mass spectrometry revealed 3-methylglutaconic aciduria(3-MGCA)in 8 of 13 tested patients.Fifteen types of TAZ gene mutation were identified in the 18 patients,including 5 novel mutations.Genetic testing of the parents of 16 patients indicated maternal inheritance in 15 cases.The median follow-up period was 8.5(2.6,29.3)months,during which 12 patients died.The median age at death was 7.5(6.0,12.8)months.Causes of death included heart failure(7 cases,with 4 concurrent infections),sudden death(3 cases),ventricular fibrillation(1 case),and accidental death(1 case).Conclusion·BTHS is a rare genetic disorder with multisystem involvement.Its primary clinical manifestations include cardiomyopathy and neutropenia.The condition typically presents early in life,with severe progression and poor prognosis.Prompt recognition,accurate diagnosis,and early intervention are essential for managing this disease.

Objective:To analyze and verify the distribution characteristics of radiation dose on the body surface of surgeons in cardiovascular interventional treatment,so as to provide theoretical basis for studying the characteristics of radiation dose and implementing radiation protection correctly.Methods:During cardiovascular interventional surgery,three pieces of lead protective clothing(designated as lead protective clothing A,B,and C)were provided in the room of digital subtraction angiography(DSA)equipment.Each piece of these protective clothing included one lead scarf,one lead vest and one lead apron,and the lead equivalents of them were all 0.5 mmPb.A thermoluminescence dosimeter was placed on the outer surface of the lead protective clothing that was worn by surgeon,and the radiation dose values of the front and back,vertical and horizontal surfaces of the three pieces of lead protective clothing were compared.Results:The measured average values of the front dosimeter of the three pieces of lead protective clothing were respectively(296.2±31.9)mSv,(196.3±20.2)mSv and(299.4±33.0)mSv,which were significantly higher than those of the back of the lead protective clothing,and the differences were statistically significant(Z=-5.522,-5.115,-4.817,Z=-5.522,-5.115,-4.817,P<0.05).The values of abdominal radiation doses on the vertical plane of the three pieces of lead protective clothing were the highest,which were respectively(356.7±58.2)mSv,(217.7±31.8)mSv and(387.4±46.3)mSv.The measured values of the dosimeter on the left side of the horizontal plane of the A,B of lead protective clothing were respectively(341.6±58.5)mSv and(229.1±32.4)mSv,which were all higher than that on the right side,with statistical significances(Z=5.890,9.068,P<0.05).The measured value of the left side of lead protective clothing was respectively higher than that of the middle side and the right side,and the differences were statistically significant(Z=5.846,9.766,P<0.05).Conclusion:The radiation dose of the front of the body surface of surgeon who undergo DSA intervention is significantly higher than that in the back of that,and the radiation dose of the abdomen on the vertical plane of the body is the highest,and the radiation dose of horizontal plane appears a decreasing trend from left to right.The detected dose data and distribution characteristics of radiation can provide research basis for radiation protection.

Objective:To investigate the value of soluble interleukin-6 (IL-6) receptor (sIL-6R) level in predicting ultrafiltration insufficiency in peritoneal dialysis (PD) patients.Methods:It was a prospective cohort study. The patients who received continuous ambulatory PD and regular follow-up between November 2016 and July 2018 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled. Enzyme-linked immunosorbent assay was used to determine dialysate sIL-6R and its appearance rate (AR) was calculated. Patients were divided into high sIL-6R AR group and low sIL-6R AR group according to median value of sIL-6R AR and prospectively followed up until death, PD cessation, or the end of the study (December 31, 2022). Multiple linear regression was used to analyze the related factors of sIL-6R AR. Kaplan-Meier method and log-rank test were used to compare the survival rate difference of ultrafiltration insufficiency between high sIL-6R AR group and low sIL-6R AR group. Multivariate Cox regression and multivariate competing risk models were used to assess the risk factors associated with occurrence of ultrafiltration insufficiency.Results:A total of 198 PD patients were enrolled, including 115 (58.1%) males, with age of (54.9±13.7) years old and PD duration of 22.5 (6.6, 65.0) months. The sIL-6R AR of the cohort was 2 094.7 (1 672.4, 2 920.9) pg/min. Compared with low sIL-6R AR（<2 094.7 pg/min）group, high sIL-6R AR（>2 094.7 pg/min）group had older age ( t=-3.269, P=0.001), higher body mass index ( t=-3.248, P=0.001), proportion of combined diabetes mellitus ( χ2=8.890, P=0.003), 24 h glucose exposure ( Z=-2.257, P=0.024), 24 h ultrafiltration capacity ( Z=-2.515, P=0.012), 4 h dialysate creatinine to serum creatinine ratio ( t=-2.609, P=0.010), mass transfer area coefficient of creatinine ( Z=-2.308, P=0.021), IL-6 AR ( Z=-3.533, P<0.001) and solute glycoprotein 130 AR ( Z=-8.670, P<0.001), and lower serum albumin ( t=2.595, P=0.010) and residual renal function ( t=2.133, P=0.033). Multiple linear regression analysis showed that body mass index ( β=0.194, P=0.005), serum albumin ( β=-0.215, P=0.002) and dialysate lg[IL-6 AR] ( β=0.197, P=0.011) were independently correlated with sIL-6R AR. By the end of the study, 57 (28.8%) patients developed ultrafiltration insufficiency. Kaplan-Meier analysis showed that high sIL-6R AR group had a significantly inferior ultrafiltration insufficiency-free survival rate than that in low sIL-6R AR group (log-rank χ 2=5.375, P=0.020). Multivariate Cox regression analysis and multivariate competing risk models showed that high dialysate sIL-6R AR (>2 094.7 pg/min) was an independent influencing factor of ultrafiltration insufficiency ( HR=2.286 , 95% CI 1.254-4.165 , P=0.007 ; SHR=2.074, 95% CI 1.124-3.828, P=0.020) in PD patients. Conclusions:Dialysate sIL-6R level was associated with body mass index, serum albumin and dialysate IL-6 level. Dialysate sIL-6R may be a predictive factor of ultrafiltration insufficiency in PD patients.

Objective: To investigate the epidemiological characteristics of human brucellosis in Jiaxing City from 2010 to 2021, so as to provide insights into the development of the brucellosis control strategy. Methods: The epidemiological and clinical data of brucellosis patients and epidemiological data of brucellosis outbreaks in Jiaxing City from 2010 to 2021 were collected from Chinese Disease Control and Prevention Information System, and the epidemiological features and outbreaks of brucellosis were analyzed descriptively. Results: Totally 160 brucellosis patients were reported in Jiaxing City from 2010 to 2021, and the incidence of brucellosis appeared a tendency towards a rise (χ2trend=28.564, P=0.002), with annual mean incidence of 0.29/105. No deaths due to brucellosis occurred in Jiaxing City from 2010 to 2021. Brucellosis cases were reported each month, which were concentrated in the first and second quarters, and the greatest number was seen in May (27 cases, 16.88%). The brucellosis cases were predominantly reported in Tongxiang City (114 cases, 71.25%), and 75.00% were male (120 cases) and 70.63% were occupational populations (113 cases). The patients had a median (interquartile range) age of 57 (12) years at onset, and the median duration (interquartile range) from onset to definitive diagnosis was 18 (28) days. The clinical manifestations mainly included fever and weakness, and a total of 18 Brucella melitensis isolates and one B. bovis isolate were cultured. Conclusions The incidence of brucellosis was rising in Jiaxing City from 2010 to 2021. The brucellosis patients were predominantly reported in Tongxiang City in the first and second quarters, and young, middle-aged men and occupational populations were at a high risk of brucellosis.

BACKGROUND: The effect of intra-operative chemotherapy (IOC) on the long-term survival of patients with colorectal cancer (CRC) remains unclear. In this study, we evaluated the independent effect of intra-operative infusion of 5-fluorouracil in combination with calcium folinate on the survival of CRC patients following radical resection. METHODS: 1820 patients were recruited, and 1263 received IOC and 557 did not. Clinical and demographic data were collected, including overall survival (OS), clinicopathological features, and treatment strategies. Risk factors for IOC-related deaths were identified using multivariate Cox proportional hazards models. A regression model was developed to analyze the independent effects of IOC. RESULTS: Proportional hazard regression analysis showed that IOC (hazard ratio [HR]=0.53, 95% confidence intervals [CI] [0.43, 0.65], P  < 0.001) was a protective factor for the survival of patients. The mean overall survival time in IOC group was 82.50 (95% CI [80.52, 84.49]) months, and 71.21 (95% CI [67.92, 74.50]) months in non-IOC group. The OS in IOC-treated patients were significantly higher than non-IOC-treated patients ( P  < 0.001, log-rank test). Further analysis revealed that IOC decreased the risk of death in patients with CRC in a non-adjusted model (HR=0.53, 95% CI [0.43, 0.65], P  < 0.001), model 2 (adjusted for age and gender, HR=0.52, 95% CI [0.43, 0.64], P  < 0.001), and model 3 (adjusted for all factors, 95% CI 0.71 [0.55, 0.90], P  = 0.006). The subgroup analysis showed that the HR for the effect of IOC on survival was lower in patients with stage II (HR = 0.46, 95% CI [0.31, 0.67]) or III disease (HR=0.59, 95% CI [0.45, 0.76]), regardless of pre-operative radiotherapy (HR=0.55, 95% CI [0.45, 0.68]) or pre-operative chemotherapy (HR=0.54, 95% CI [0.44, 0.66]). CONCLUSIONS: IOC is an independent factor that influences the survival of CRC patients. It improved the OS of patients with stages II and III CRC after radical surgery.
