Objective To investigate neutrophil lymphocyte ratio (NLR) in early-stage diabetic nephropathy and its clinic significance. Methods The 145 subjects were divided into two groups:the healthy control group (n=54) and early stage diabetic nephropathy group (n=91). The numbers of neutrophils (N) and lymphocytes (L) as well as the NLR values of peripheral blood and other biochemistry index were examined. Factors of early stage diabetic nephropathy were calculated us?ing variance and logistic regression analysis. Results Creatinine(Cr), total cholesterol(TC), triglyceride(TG), LDL-C, neu?trophils number and CRP in DN group were significantly higher than those of the control group and lymphocytes numbers of DN group were significantly lower than that of the control group (P<0.05 respectively);NLR values were significantly higher in diabetic nephropathy group compared with those of healthy control group(2.52±0.57 vs 1.82±0.60,t=6.997, P<0.01). Lo?gistic regression analysis showed that the risk factors of DN include NLR, TG and total cholesterol. NLR ( P <0.001, OR=8.951, OR 95%CI:3.595-22.287) was significantly associated with DN. Conclusion High NLR values may be a predic?tive and reliable marker ofearly-stage DN.

PURPOSE: The microRNA-34 (miR-34) family is important in tumor regulation. This study aimed to investigate the association of circulating miR-34 family proteins with clinicopathological features and their prognostic value in triple-negative breast cancer (TNBC) patients. MATERIALS AND METHODS: In this cohort study, 173 TNBC patients admitted to First People's Hospital of Shunde from May 1, 2009 to April 30, 2013 were enrolled. Meanwhile, 75 age-matched healthy women volunteers were identified as healthy controls (HCs). We examined the expression of miR-34 family (miR-34a/b/c) proteins in plasma collected from TNBC patients before any treatment was performed and from age-matched HCs using qPCR methods. RESULTS: The expressions of miR-34a/34b/34c were significantly lower in TNBC patients than in HC (p<0.001, p=0.027, p<0.001, respectively). miR-34a was correlated with tumor grade (p=0.038), lymph node positive (p=0.027), distant metastasis (p=0.004), and surgery (p=0.023); miR-34b was correlated with lymph node positivity (p=0.027); and miR-34c was correlated with tumor grade (p=0.017) and distant metastasis (p<0.001). Kaplan-Meier curve analysis displayed low expression of miR-34a as associated with worse overall survival (OS) (p=0.011), as well as miR-34c low expression (p=0.002). In addition, univariate and multivariate Cox proportional hazards regression was performed, and low expression of miR-34c (p=0.011) was found to be an independent risk factor for OS, as well as tumor grade (p=0.013), lymph node positive (p=0.050), and distant metastasis (p=0.021). CONCLUSION: In conclusion, this study demonstrated reduced miR-34a/c expression is highly associated with tumor progression and indicated worse prognosis. Also, miR-34c was an independent risk factor for OS in TNBC patients.

[Objectives]To investigate the protective effects of recombinant Trichinella spiralis excretory-secretory 53ku pro-tein(rTsP53)on acute lung injuries in mice.[Methods]Thirty Balb/c mice were randomly divided into normal group. ALI group and rTsP53 group(n=10,respectively). Macrophages were harvested by bronchoalveolar lavage. Mortality in 72 hours was counted and compared. Pathological damage of lung tissues was observed by HE staining and graded by Smith score. Wet/dry ratio was measured. The bronchoalveolar lavage fluid concertration of IL-6 and IL-4 was measured by ELISA. The mRNA expression of TNF-α,iNOS, IL-10 and Arg-1 in alveolar lavage macrophages was detected by RT-PCR.[Results]72 h mortality of ALI mice was 70%,which was reduced to 30% in mice received rTsP53 treatment. Compared with ALI mice,the pathological damage of in rTsP53 treated-mice was improved and Smith score was declined ,combined with descending W/D ratio. IL-6 level of alveolar lavage fluid was elevated in ALI mice compared with normal group. And alveolar lavage macrophage was polarized to M2 sub-type,appeared as higher mRNA expression of TNF-α and iNOS and lower level of IL-10 and Arg-1. Bronchoalveolar lavage fluid concentration of IL-6 was declined and IL-4 was elevated in rTsP53-treated mice compared with ALI group. The macrophages of alveolar wash had higher mRNA expression of IL-10 and Arg-1,while lower level of TNF-α and iNOS,manifesting M2 polarization characteristics.[Conclusion]Recombinant T.spiralis P53 protein could protect mice from acute lung injuries induced by LPS via modulating M2 macrophage polarization,which play a role in depression of inflammatory reaction and tissue repairment.

Objective To evaluate the impacts of air temperature on years of life lost(YLL) among the residents in Guangzhou and Zhuhai,Guangdong province. Methods Daily mortality and meteorology data in Guangzhou and Zhuhai were collected,and distributed lag non-linear model (DLNM)was used to evaluate the cumulative and delayed effects of daily air temperature on YLL of total non-accident mortality. The accumulative effect of air temperature on mortality under the extreme high temperature(0-1 days)and extreme low temperature(0-13 days)situation in Guangzhou and Zhuhai were analyzed respectively. Results The average YLL was 1 928.0 in Guangzhou and 202.5 in Zhuhai. The exposure-response functions seemed to be non-linear. The hot effect seemed to be acute and reached the peak at the same day,while the cold effect reached the peak at 5th days and lasted for about two weeks. Low temperature had stronger gross effect than high temperature had. The cold effect among males was greater than that among females in Guangzhou. The hot/cold effect on YLL was greater in people aged ≥65 years than in people aged <65 years and in people suffering from respiratory disease than in people suffering from cardiovascular disease in both Guangzhou and Zhuhai. Conclusion The effects of high and low temperatures on YLL were obvious,and the impact of low temperature was greater. The elderly and people suffering from respiratory disease or cardiovascular disease are the vulnerable populations.

Objective:Hepatic fibrosis is a common pathological basis for many chronic liver diseases and can progress to cirrhosis,a leading cause of mortality in liver diseases.Early identification and reversal of hepatic fibrosis are key in the treatment of chronic liver disease.This study aims to compare the expression levels of serum core fucosylated low molecular weight kininogen(LMWK-Fc)and alpha-galactosylated(α-Gal)antibodies in patients with hepatic fibrosis at different stages,and to evaluate their diagnostic efficacy for hepatic fibrosis. Methods:A retrospective analysis was conducted on 275 patients with chronic liver disease who visited the Department of Infectious Diseases at the Second Xiangya Hospital of Central South University between June 2022 and March 2023.Among these,115 patients underwent liver biopsy.Based on the extent of collagen deposition and its impact on liver structure and microcirculation,patients were staged from 0 to 4:S0(no significant collagen deposition in liver tissues;liver structure and microcirculation are normal),S1(mild collagen deposition in liver tissues,with partial disruption of lobule structure,but microcirculation remains largely normal),S2(moderate collagen deposition in liver tissues,with partial disruption of lobule structure and microcirculation),S3(extensive collagen deposition in liver tissues,with substantial disruption of lobule structure and microcirculation),and S4(development of cirrhosis,with heavy collagen deposition,complete disruption of lobule structure,and severe impairment of microcirculation).Patients were grouped as no fibrosis(S0),fibrosis(S1-S2),and significant fibrosis(S3-S4).For the 160 patients without liver biopsy,they were categorized based on liver stiffness measurement(LSM)value:no fibrosis(F0:LSM＜7.3 kPa),fibrosis(F1-F2:LSM 7.3-12.4 kPa),and significant fibrosis(F3-F4:LSM＞12.4 kPa).Demographic data(age,gender)and laboratory indicators(alanine transaminase,aspartate transaminase,gamma-glutamyl transferase,alkaline phosphatase,alpha-fetoprotein,platelet count)were collected to calculate the fibrosis-4 index(FIB-4)and aspartate aminotransferase-to-platelet ratio index(APRI).Serum LMWK-Fc and α-Gal antibodies were measured and compared across the groups,and their correlation with fibrosis severity was analyzed.The receiver operating characteristic(ROC)curve was used to assess the predictive value of serum LMWK-Fc and α-Gal antibody levels for hepatic fibrosis. Results:Among the 160 patients without complete liver biopsy,serum α-Gal antibody and LMWK-Fc levels increased progressively from the no fibrosis group to the significant fibrosis group,with statistically significant differences(P＜0.05).Among the 115 patients with liver biopsy,serum LMWK-Fc levels were significantly higher in the fibrosis group and the significant fibrosis groups compared with the no fibrosis group,and α-Gal antibody levels were significantly higher in the significant fibrosis group compared with the no fibrosis group and the fibrosis group(P＜0.001,P=0.032,respectively).Univariate and multivariate linear regression analyses showed that hepatic fibrosis was correlated with gender and LMWK-Fc levels(both P＜0.05),but not with age,α-Gal antibody levels,FIB-4,or APRI(all P＞0.05). Conclusion:The expression levels of serum LMWK-Fc and α-Gal antibodies vary across different stages of hepatic fibrosis,suggesting a potential association with fibrosis progression.LMWK-Fc levels have a certain predictive value for the diagnosis of hepatic fibrosis.

Objective: To compare the clinical outcomes and biomechanical characteristics of 1-, 2-, and 3-level pedicle subtraction osteotomy (PSO), and establish selection criteria based on preoperative radiographic parameters. Methods: Patients undergone PSO to treat ankylosing spondylitis from February 2009 to May 2019 in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were enrolled. According to the quantity of osteotomy performed, the participants were divided into group A (1-level PSO, n = 24), group B (2-level PSO, n = 19), and group C (3-level PSO, n = 11). Clinical outcomes were assessed before surgery and at the final follow-up. Comparisons of the radiographic parameters and quality-of-life indicators were performed among and within these groups, and the selection criteria were established by regression. Finite element analysis was conducted to compare the biomechanical characteristics of the spine treated with different quantity of osteotomies under different working conditions. Results: Three-level PSO improved the sagittal parameters more significantly, but resulted in longer operative time and greater blood loss (p < 0.05). Greater stress was found in the proximal screws and proximal junction area of the vertebra in the model simulating 1-level PSO. Larger stress of screws and vertebra was observed at the distal end in the model simulating 3-level PSO. Conclusion Multilevel PSO works better for larger deformity correction than single-level PSO by allowing greater sagittal parameter correction and obtaining a better distribution of stress in the hardware construct, although with longer operation time and greater blood loss. Three-level osteotomy is recommended for the patients with preoperative of global kyphosis > 85.95°, T1 pelvic angle > 62.3°, sagittal vertical alignment > 299.55 mm, and pelvic tilt+ chin-brow vertical angle > 109.6°.
