Translationally controlled tumor protein (TCTP) is widely expressed in most animal and plant cells and is involved in various physiological activities. Studies have shown that liver cancer tissue has significantly higher expression of TCTP than normal tissue. This article introduces the main biological functions of TCTP, such as promoting cell growth and development, regulating cell cycle, inhibiting cell apoptosis, reducing cell stress response, and regulating inflammatory response. Besides changing cell cycle and inhibiting cell apoptosis, TCTP can also induce mitotic defects and chromosomal instability, mediate inflammatory response and hepatic fibrosis, and thus promote the development and progression of hepatocellular carcinoma(HCC). It is pointed out that TCTP might be used as a potential marker for the early diagnosis of HCC, and targeted reduction of TCTP expression might be a new method for the treatment of HCC.

OBJECTIVETo explore the molecular biological mechanism of Arnebia Root oil (AO) in promoting the recovery of surface of wound by observing basic fibroblast growth factor (bFGF) mRNA expression in the wound tissue and healing rate of the wound.

METHODSPatients in the observed group with their wound treated by AO and those in the control group treated by petrolatum gauze. The wound surface healing rate was estimated and bFGF mRNA expression was observed by RT-PCR.

RESULTSEndogenous bFGF mRNA expression existed in the wound surface of both groups, but its level in the observed group at any time point was obviously higher than that in the control group respectively, with significant difference in comparison of the gray density between the two groups (P < 0.05). The wound surface healing rate kept abreast with bFGF mRNA expression in wound tissues, so it was significantly higher in the observed group than that in the control group (P < 0.05). GAPDH gene, which was taken as a parameter for internal reference, expressed with a certain amount unchanged in different periods of healing (P > 0.05 ).

CONCLUSIONAO shows obviously promotive action on bFGF, an important regulatory factor on wound healing, it might complete the recovery process by stimulating the increase of bFGF.

Objective To investigate the effect of the number of sentinel lymph node (SLN) dissection on prediction of non-sentinel lymph node (nSLN) metastasis in SLN biopsy in patients with early-stage breast cancer. Methods A retrospective analysis of clinical and pathological data of 82 patients with early-stage breast cancer who underwent SLN biopsy and axillary lymph node dissection in the Affiliated Cancer Hospital of Shanxi Medical University from January 2015 to December 2016 was conducted, and the univariate analysis and logistic multivariate regression analysis were performed to analyze the influencing factors of nSLN metastasis. Results Univariate analysis showed that nSLN metastasis was associated with histological grade (χ2 = 10.114, P= 0.006), vascular invasion (χ2 = 12.381, P< 0.01), and the number of positive SLN ≥2 (χ2=13.734, P<0.01), however, it was not related to patient's age, tumor size, SLN metastasis rate, molecular subtype and pathological type (all P>0.05). Multivariate analysis showed that the number of positive SLN≥2 was an independent influencing factor of nSLN metastasis (OR= 4.145, P= 0.015). Conclusions Surgeons need to ensure that the number of SLN dissection is > 2 when the SLN biopsy is performed in patients with breast cancer. When the number of positive SLN is≥2, the risk of nSLN metastasis increases.

PURPOSE: MicroRNAs (miRs) were recently recognized to be important for immune cell differentiation and immune regulation. However, whether miRs were involved in allergen-specific immunotherapy (SIT) remains largely unknown. This study sought to examine changes in miR-146a and T regulatory cells in children with persistent allergic rhinitis (AR) after 3 months of subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT). METHODS: Twenty-four HDM-sensitized children with persistent AR were enrolled and treated with SCIT (n=13) or SLIT (n=11) for 3 months. Relative miR-146a and Foxp3 mRNA expression, the TRAF6 protein level, and the ratio of post-treatment to baseline IL-10+CD4+ T cells between the SCIT and SLIT groups were examined in the peripheral blood mononuclear cells (PBMCs) of AR patients using quantitative reverse transcription polymerase chain reaction (qRT-PCR), flow cytometry, and Western blot analysis, respectively. Serum levels of IL-5 and IL-10 were determined using ELISA. RESULTS: After 3 months of SIT, both the TNSS and INSS scores were significantly decreased compared to the baseline value (P<0.01). The relative expression of miR-146a and Foxp3 mRNA was significantly increased after both SCIT and SLIT (P<0.01). The ratio of post-treatment to baseline IL-10+CD4+ T cells and the serum IL-10 level were significantly increased in both the SCIT and SLIT groups (P<0.01), whereas the TRAF6 protein level and serum IL-5 level were significantly decreased (P<0.01). No significant differences in these biomarkers were observed between the SCIT and SLIT groups. CONCLUSIONS: Our findings suggest that miR-146a and its related biomarkers may be comparably modulated after both SCIT and SLIT, highlighting miR-146a as a potential therapeutic target for the improved management of AR.

Objective To investigate the prevalence of HIV infection/STD and related factors in Vietnamese female sex workers (FSWs).Methods Consecutive cross-sectional surveys were conducted in June 2014,December 2014,May 2015 and November 2015 in Hekou,a county bordering Vietnam in Yunnan province.Convenience sampling were adopted to select 1 058 Vietnamese FSWs aged ＞16 years.Questionnaire interview were used to collect the information about their demographics,sexual behaviors and drug use.Serum and urine samples were collected for HIV infection/STD detection and drug use test.Trend x2 test was applied for HIV infection/STD and drug use trend analysis.Multivariate logistic regression model was used to identify the related factors.Results The consecutive cross sectional surveys indicated that the prevalence of HIV infection in Vietnamese FSWs were 3.20％(7/219),2.04％(5/245),1.89％(5/265) and 1.82％(6/329) respectively;the HSV-2 positive rates were 57.08％(125/219),58.37％(143/245),38.11％(101/265) and 51.06％ (168/329) respectively.In addition,the prevalence of syphilis were 0.91％,1.51％,0.75％ and 1.22％ respectively.HSV-2 infection prevalence showed a downward trend (x2=4.823,P=0.028).By logistic regression analysis,the related factors for HIV infection in Vietnamese FSWs were being amphetamine type stimulants (ATS) positive (OR=10.18,95％ CI:4.33-23.92) and being HSV-2 positive (OR=2.89,95％CI:1.09-7.88);Age (OR=1.88,95％CI:1.32-2.61),no-paid sexual partner (OR=1.59,95％CI:1.26-2.01) and being ATS positive (OR=2.48,95％CI:1.10-5.57) were related factors for HSV-2 infection.Conclusions Compared with the results of previous studies,the HIV infection prevalence declined in Vietnamese FSWs,but the HSV-2 infection prevalence was still high.The association between ATS use and HIV infection/STD suggested the necessity of strengthening AIDS intervention in Vietnamese FSWs,including the control of new type drug and sexual transmission.

Objective:To analyze mobility limitation condition and its relationship with cognitive function in community-dwelling elderly.Methods:In this cross-sectional study, a total of 1 935 older adults aged≥60 years were recruited from May to September 2023 in Beijing Baizhifang Community Health Service Center and its five subordinate health service stations (Baizhifang Hutong health service station, Nancaiyuan community health service station, Youanmen community health service station, Younei West Street health service station and Shuanghuaili community health service station). The Short Physical Performance Battery (SPPB) was used to assess the mobility capacity of the elderly, and the elderly were divided into two groups with SPPB, the elderly with a SPPB≤9 points were grouped into mobility limitation group (645 cases), and the ones with a SPPB≥10 points were considered with normal mobility capacity (1 290 cases). The cognitive function of the older adults was assessed with the mini-mental state examination; and the gender, age, calf circumference, history of chronic disease, frailty status, cognitive function, nutritional status, depression status, hearing and vision condition of the two groups were compared with χ2 test or Mann-Whitney U non-parametric test. Multiple logistic regression analysis was used to analyze the mobility limitation and its relationship with cognitive function in the older adults. Results:Mobility limitation was found in 33.33% (645/1 935) of community-dwelling older adults. The proportions of advanced age, female, hypertension, diabetes, coronary heart disease, stroke, chronic obstructive pulmonary disease, frailty, depression, cognitive impairment, hearing decline, and vision decline in the mobility limitation group were all significantly higher than those in the normal mobility capacity group (31.32% vs 13.41%, 69.92% vs 59.61%, 65.27% vs 54.03%, 33.80% vs 28.60%, 27.91% vs 19.53%, 17.83% vs 11.47%, 10.54% vs 7.36%, 13.18% vs 2.02%, 18.45% vs 6.59%, 14.73% vs 7.75%, 30.54% vs 20.31%, 45.58% vs 30.39%) (all P<0.05). Advanced age ( OR=2.542, 95% CI: 1.977-3.269), female ( OR=1.736, 95% CI: 1.390-2.167), stroke ( OR=1.426, 95% CI: 1.065-1.911), depression ( OR=2.292, 95% CI: 1.656-3.174), cognitive impairment ( OR=1.601, 95% CI: 1.154-2.220), frailty ( OR=5.199, 95% CI: 3.219-8.397) and vision decline ( OR=1.405, 95% CI: 1.124-1.756) were all positively correlated with the mobility limitation in the community-dwelling older adults (all P<0.05). Conclusion:The older adults in the community have a higher risk of mobility limitation, mobility limitation is a positive correlation factor of cognitive impairment.

Currently, there is still no effective curative treatment for the development of late-stage liver fibrosis. Here, we have illustrated that TB001, a dual glucagon-like peptide-1 receptor/glucagon receptor (GLP-1R/GCGR) agonist with higher affinity towards GCGR, could retard the progression of liver fibrosis in various rodent models, with remarkable potency, selectivity, extended half-life and low toxicity. Four types of liver fibrosis animal models which were induced by CCl₄, α-naphthyl-isothiocyanate (ANIT), bile duct ligation (BDL) and Schistosoma japonicum were used in our study. We found that TB001 treatment dose-dependently significantly attenuated liver injury and collagen accumulation in these animal models. In addition to decreased levels of extracellular matrix (ECM) accumulation during hepatic injury, activation of hepatic stellate cells was also inhibited via suppression of TGF-β expression as well as downstream Smad signaling pathways particularly in CCl₄-and S. japonicum-induced liver fibrosis. Moreover, TB001 attenuated liver fibrosis through blocking downstream activation of pro-inflammatory nuclear factor kappa B/NF-kappa-B inhibitor alpha (NFκB/IKBα) pathways as well as c-Jun N-terminal kinase (JNK)-dependent induction of hepatocyte apoptosis. Furthermore, GLP-1R and/or GCGR knock-down results represented GCGR played an important role in ameliorating CCl₄-induced hepatic fibrosis. Therefore, TB001 can be used as a promising therapeutic candidate for the treatment of multiple causes of hepatic fibrosis demonstrated by our extensive pre-clinical evaluation of TB001.

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.
