XRCC1 Arg399Gln and Arg194Trp polymorphisms regulate XRCC1 expression and chemoresistance of non-small cell lung cancer cells

X-ray repair cross-complementing protein 1(XRCC1)could repair cisplatin-induced DNA damage.XRCC1 Arg399Gln and Arg194Trp variants alter XRCC1 expression and function,leading to changes in cancer sensitivity to cisplatin treatment.This study aimed to investigate the effects of XRCC1 Arg399Gln and Arg194Trp polymorphisms on cell viability,apoptosis and XRCC1 expression in cisplatin-sensitive A549 and cisplatin-resistant A549/DDP non-small cell lung cancer(NSCLC)cells.Plasmids carrying XRCC1 Arg399Gln and Arg194Trp were constructed and transfected into A549 and A549/DDP cells.RT-PCR,Western blot,MTT assay,and flow cytometry analysis were performed to assess cell viability,apoptosis,and XRCC1 expression.Compared to control cells,the viability of A549 and A549/DDP cells transfected with XRCC1 Arg399Gln and Arg194Trp was higher and the apoptosis rate was lower,and XRCC1 mRNA and protein expression levels were significantly higher.In conclusion,our results suggest that XRCC1 Arg399Gln and Arg194Trp polymorphisms change XRCC1 expression in NSCLC cells and alter the sensitivity of NSCLC to cisplatin-based chemotherapy.

Triple negative breast cancer: 5 years follow-up

Objective： The aim of the study was to investigate the long-term therapeutic effects of triple negative breast cancers （TNBCs） and find a standardized treatment. Methods： The clinical data and survival status of 69 patients with TNBC were collected, who were treated from 2003 to 2007 at Chongqing Cancer Institute, China. Results： Median observation for 61 months showed the local recurrence rate was 13.0% （9/69）, the overall survival （OS） rate was 76.8% （53/69） and the disease free survival （DFS） rate was 59.4% （41169）. Log-rank univariate survival analysis showed the OS and DFS rates of TNBCs with axillary lymph node metastasis were 38.1% and 23.8%, respectively, and the OS and DFS rates of triple negative breast cancer with axillary lymph node non-metastasis were 93.6% and 75.0%, respectively. There were significant differences comparing with two groups. Indictor analysis of age, menstruation status, tumor size, TNM stage, histological type, neoadjuvant chemotherapy and p53 did not show any prognostic influence. Conclusion： The axillary nodes metastasis is associated with DFS and OS in triple negative breast cancers. Cisplatin-based chemotherapy may be good choice for triple negative breast cancers with metastasis or local recurrence, who received Anthracycline and Taxane-based chemotherapy. Targeted therapies strategies such as EGFR-targeted therapy may be necessary.

Interpectoral Nodes Metastases in Breast Cancer

Objective： To study interpectoral nodes metastasis rate in breast cancer and its clinical significance. Methods： 171 female patients undergone surgery for breast cancer were reviewed, of whom the interpectoral nodes were subjected to pathological examination. Results： Interpectoral nodes were identified in 25.7% of the 171 female patients, and the interpectoral nodes metastasis rate was 9.9%. The patients with interpectoral nodes metastasis had larger tumor size, later TNM classification, higher axillary apical nodes metastasis rate and lower ER positive rate. Conclusion： Dissection of interpectoral nodes should be regard as routine clinical practice in modified radical mastectomy, and interpectoral nodes should be subjected to pathological examination.

Clinicopathological Characters of Triple Negative Breast Cancer

Objective： To study the clinicopathological characters Methods： A total of 629 patients with breast cancer of triple negative breast cancer （TNBC）. were reviewed, who were treated from 2003 to 2007 in Chongqing Cancer Institute. The comparison of clinicopathological features including TNM classification, histological type, tumor location, axillary lymphonodes status and neoadjuvant chemotherapy between TNBC and nontriple negative breast cancer （NTNBC） was performed. The overall response was evaluated by whether the patients achieve complete remission （CR） and partial remission （PR） after chemotherapy. Results： There were 69 TNBCs in the 629 patients with breast cancer. The premenopausal patients, which was found in 49/69 of TNBCs, was more than NTNBCs. The average diameter of tumor in TNBC group was 4.1 cm, lager than NTNBC group. TNBC with axillary nodes metastasis occurred in 21 cases, and the axillary nodes metastasis rate was lower than NTNBC. The positive expression rate of p53 in TNBC was 44.9%, and the overall response （CR＋PR） was 72.2%. No statistical differences were found regarding the positive expression rate of p53 and the overall response between TNBC and NTNBC. Conclusion： TNBC were a group of primary breast cancers with triple negative, tending to occur in premenopausal women, with larger tumors, lower axillary nodes metastasis rate. TNBC had worse clinical prognosis and currently lacked effective targeted therapies.

Carbon Nanoparticles for Identifying Lymph Nodes during Surgery in Colorectal Cancer: A Meta-Analysis

Aim: To investigative the efficacy of carbon nanoparticles (CNs) to identify the lymph nodes during radical surgery in colorectal cancer. Method: The MEDLINE, EMBASE and Cochrane Library databases were searched electronically to identify the studies that compared the use of CNs (CN group) with control group in patients undergoing colorectal cancer radical surgery (from January 2009 to November 2018). The primary outcome was the number of retrieved central lymph nodes. Results: This meta-analysis identified 2 randomized controlled trials and 5 non-randomized controlled trials. Compared with the control group, the CN group resulted in an average of 7.16 more lymph nodes removed per patient (WMD = 7.16, 95% CI = 3.76 to 10.57, p < 0.01), 7.26 minutes less required for retrieving lymph nodes (WMD = -7.26, 95% CI = -13.43 to -1.09, p = 0.02), and 15.1 ml less blood loss during operation (WMD = -15.11, 95% CI = -23.15 to -7.06, p < 0.01). Although there was no significant difference in the metastatic lymph nodes between the two groups (OR = 1.02, 95% CI = 0.79 to 1.31, p = 0.87), there was 1.45 times more metastatic lymph of the stained nodes in CN group than in the control group (OR = 1.45, 95% CI = 1.13 to 1.85, p < 0.01). In addition, lymph nodes less than 5 mm were detected significantly more in the CN group than in the control group (OR = 2.15, 95% CI = 1.77 to 2.63, p < 0.01). Conclusions: The technique of CNs labeled lymph node staining in curative colorectal carcinoma is easy and effective, which can improve the retrieved number of lymph nodes, especially for nodes < 5 mm. The black stained lymph node indicates higher risk of metastasis. Further high quality RCT is needed to verify these conclusions.

Assessment of the expression pattern of HER2 and its correlation with HER2-targeting antibody-drug conjugate therapy in urothelial cancer

Background:Human epidermal growth factor receptor 2(HER2)overexpression is related to anti-HER2 therapy in many tumors.RC48-antibody-drug conjugate(ADC)has shown promising efficacy in patients with HER2-positive locally advanced or metastatic urothelial carcinoma(UC).The characteristic expression and scoring systems of HER2 are nonexistent in UC.We aimed to explore HER2 status and its correlation with the efficacy of HER2-targeting ADC therapy in UC.Methods:A total of 137 and 43 patients were enrolled in cohort 1 and cohort 2,respectively,from March 2009 to December 2018.The patients in cohort 2 were enrolled in a phase II study of RC48-ADC.UC samples were tested for HER2 status using immunohistochemistry(IHC)and/or fluorescence in situ hybridization(FISH).The 2018 ASCO/CAP HER2 scoring system was adopted and modified to score HER2 expression in UC.Results:The HER2-positive(IHC 2+or 3+)rate was 24.1%(33/137).In HER2 IHC 2+or 3+patients,the HER2 gene amplification rate was 31%(13/42).The objective response rates(ORRs)in RC48-ADC-treated patients with IHC 3+,IHC 2+and FISH+,IHC 2+and FISH-were 58.8%,66.7%and 40%,respectively.The ORR showed a trend toward a better benefit for RC48-ADC therapy in patients with HER2 amplification than in those without amplification(61.5%vs.44.8%,P=0.059).The heterogeneity of HER2 expression in the primary tumor was 55.5%(15/27),and the ORR was not significantly different between patients with tumor heterogeneity and homogeneity.Conclusions:IHC testing should be performed to assess the HER2 status before the initiation of HER2-ADC therapy.There was a trend toward a better benefit for patients with HER2 amplification,and tumor heterogeneity did not influence the drug efficacy.

Recurrent multisystem Langerhans cell histiocytosis involving the female genitalia: A case report

BACKGROUND Langerhans cell histiocytosis(LCH)is a histiocytic proliferative disease caused by clonal proliferation of Langerhans cells,which is currently defined as an inflam-matory myeloid tumor.It is rare in adults,with an incidence of 1–2 per million,and is highly heterogeneous in clinical presentation,with unpredictable disease progression and outcome.CASE SUMMARY A 52-year-old postmenopausal female patient presented to the gynecology department in July 2023 with bilateral vulvar masses.She was diagnosed with recurrent multisystem LCH.The patient had previously been diagnosed with a single-system and single-focal LCH in October 2021 due to a right maxillofacial mass,which resolved after surgical treatment.A chemotherapy regimen was developed after multidisciplinary consultation.Six cycles of chemotherapy resulted in partial remission,and maintenance chemotherapy is currently being administered.CONCLUSION Recurrent LCH involving the bilateral vulva has been poorly reported.Compre-hensive imaging and pathological evaluation is important for diagnosis.The model of joint multidisciplinary specialist diagnosis and treatment is worthy of clinical application.

Efficacy of Huangma Ding or autologous platelet-rich gel for the diabetic lower extremity arterial disease patients with foot ulcers

BACKGROUND Diabetes foot is one of the most serious complications of diabetes and an important cause of death and disability,traditional treatment has poor efficacy and there is an urgent need to develop a practical treatment method.AIM To investigate whether Huangma Ding or autologous platelet-rich gel(APG)treatment would benefit diabetic lower extremity arterial disease(LEAD)patients with foot ulcers.METHODS A total of 155 diabetic LEAD patients with foot ulcers were enrolled and divided into three groups:Group A(62 patients;basal treatment),Group B(38 patients;basal treatment and APG),and Group C(55 patients;basal treatment and Huangma Ding).All patients underwent routine follow-up visits for six months.After follow-up,we calculated the changes in all variables from baseline and determined the differences between groups and the relationships between parameters.RESULTS The infection status of the three groups before treatment was the same.Procalcitonin(PCT)improved after APG and Huangma Ding treatment more than after traditional treatment and was significantly greater in Group C than in Group B.Logistic regression analysis revealed that PCT was positively correlated with total amputation,primary amputation,and minor amputation rates.The ankle-brachial pressure and the transcutaneous oxygen pressure in Groups B and C were greater than those in Group A.The major amputation rate,minor amputation rate,and total amputation times in Groups B and C were lower than those in Group A.CONCLUSION Our research indicated that diabetic foot ulcers(DFUs)lead to major amputation,minor amputation,and total amputation through local infection and poor microcirculation and macrocirculation.Huangma Ding and APG were effective attreating DFUs.The clinical efficacy of Huangma Ding was better than that of autologous platelet gel,which may be related to the better control of local infection by Huangma Ding.This finding suggested that in patients with DFUs combined with coinfection,controlling infection is as important as improving circulation.

Inhibition of inflammatory mediator release from microglia can treat ischemic/hypoxic brain injury

Interleukin-1α and interleukin-1β aggravate neuronal injury by mediating the inf1αmmatory reaction following ischemic/hypoxic brain injury. It remains unclear whether interleukin-1α and interleukin-1β are released by microglia or astrocytes. This study prepared hippocampal slices that were subsequently subjected to oxygen and glucose deprivation. Hematoxylin-eosin staining verified that neurons exhibited hypoxic changes. Results of enzyme-linked immunosorbent assay found that interleukin-1α and interleukin-1β participated in this hypoxic process. Moreover, when hypoxic injury occurred in the hippocampus, the release of interleukin-1α and interleukin-1β was mediated by the P2X4 receptor and P2X7 receptor. Immunofluorescence staining revealed that during ischemia/hypoxia, the P2X4 receptor, P2X7 receptor, interleukin-1α and interleukin-1β expression was detectable in rat hippocampal microglia, but only P2X4 receptor and P2X7 receptor expression was detected in astrocytes. Results suggested that the P2X4 receptor and P2X7 receptor, respectively, mediated interleukin-1α and interleukin-1β released by microglia, resulting in hippocampal ischemic/hypoxic injury. Astrocytes were activated, but did not synthesize or release interleukin-1α and interleukin-1β.

Cumulative scores based on plasma D-dimer and serum albumin levels predict survival in esophageal squamous cell carcinoma patients treated with transthoracic esophagectomy

Background:Recently,studies have shown that plasma D-dimer and serum albumin are prognostic markers for esophageal cancer.The purpose of this study was to evaluate a novel prognostic scoring system—DA score(combination of preoperative plasma D-dimer and serum albumin levels)—and analyze the association between survival of patients with esophageal squamous cell carcinoma(ESCC) and their Glasgow prognostic score.Methods:In this retrospective study,preoperative biochemical markers and clinicopathologic factors in 260 ESCC patients treated with transthoracic esophagectomy were reviewed.According to receiver operating characteristic analysis,the cutoff values of D-dimer and albumin were defined as 0.5 μg/mL and 43.8 g/L,respectively.Patients with high D-dimer levels(>0.5 μg/mL) and low albumin levels(<43.8 g/L) were assigned a score of 2,those with only one of the two abnormalities were assigned a score of 1,and those with neither of the two abnormalities were assigned a score of 0.Results:ESCC patients with a DA score of 0,l,and 2 numbered 55,116,and 89,respectively.Survival analysis showed that patients with a DA score of 2 had lower overall survival(OS) rates than those with DA scores of 1 and 0(37.1%vs.52.6%and 76.4%,P < 0.001);similar findings were observed for disease-free survival(DFS) rates(32.6%vs.44.8%and67.3%,P < 0.001).In addition,the predictive value of the DA score was also significant in patients with stages l-IIA and stages IIB-IV ESCC.Multivariate Cox regression analyses indicated that hazard ratios(HRs) for predicting OS of patients with DA scores 1 and 2 were 2.25 {P — 0.010) and 3.14(P< 0.001),respectively,compared with those with a DA score of 0,and HRs for predicting DFS of patients with DA scores of 1 and 2 were 1.86(P = 0.023) and 2.68(P < 0.001),respectively,compared with those with a DA scores of 0.Conclusions:Our study suggests that preoperative DA scores are notably associated with postoperative survival of ESCC patients.

IL-37b suppresses epithelial mesenchymal transition in hepatocellular carcinoma by inhibiting IL-6/STAT3 signaling

Background: Interleukin-37 b(IL-37 b), a vital negative regulator of the innate immune system, has been reported to be a tumor inhibitor in different type of cancers. However, little is known about the relationship between IL-37 b and hepatocellular carcinoma(HCC). The present study aimed to investigate the potential roles of IL-37 b in HCC progression. Methods: Subjects( n = 237) were recruited, and serum IL-37 b was measured using ELISA. The tumorsuppressive capacity and underlying mechanisms of IL-37 b in HCC were investigated in vitro and in vivo. Results: Compared to healthy controls, serum IL-37 b levels were elevated in chronic hepatitis B(CHB) patients but decreased significantly in HBV-HCC patients, especially for those with portal venous tumor thrombus. Low level serum IL-37 b in HBV-HCC patients correlated with high HCC stage and poor overall survival and disease-free survival. In vitro and in vivo, recombinant human IL-37 b inhibited proliferation and metastasis in HCC cells. Furthermore, IL-37 b inhibited epithelial mesenchymal transition in HCC cells in vitro by downregulating IL-6, pSTAT3(Y705), N-cadherin, and vimentin expression and by upregulating E-cadherin expression. These effects were partially reversed by transfection of adenovirus encoding human IL-6. Conclusions: IL-37 b inhibits HCC growth, metastasis and epithelial mesenchymal transition by regulating IL-6/STAT3 signaling. Serum IL-37 b may be a biomarker for HBV-HCC and its staging.

Isoflurane-induced neuronal apoptosis in developing hippocampal neurons

We hypothesized that the P2X7 receptor may be the target of isoflurane, so we investigated the roles of the P2X7 receptor and inositol triphosphate receptor in calcium overload and neuronal apoptosis induced by isoflurane in cultured embryonic rat hippocampal neurons. Results showed that isoflurane induced widespread neuronal apoptosis and significantly increased cytoplasmic Ca^2＋ Blockade of P2X7 receptors or removal of extracellular Ca^2＋ combined with blockade of inositol triphosphate receptors completely inhibited apoptosis or increase in cytoplasmic Ca^2＋. Removal of extracellular Ca^2＋ or blockade of inositol triphosphate receptor alone could partly inhibit these effects of isoflurane. Isoflurane could directly activate P2X7-gated channels and induce inward currents, but did not affect the expression of P2X7 receptor protein in neurons. These findings indicate that the mechanism by which isoflurane induced neuronal apoptosis in rat developing brain was mediated by intracellular calcium overload, which was caused by P2X7 receptor mediated calcium influx and inositol triphosphate receptor mediated calcium release.

Role of Immune Microenvironmental Factors for Improving the IPI-related Risk Stratification of Aggressive B Cell Lymphoma

Objective To investigate the risk stratification of aggressive B cell lymphoma using the immune microenvironment and clinical factors. Methods A total of 127 patients with aggressive B cell lymphoma between 2014 and 2015 were enrolled in this study. CD4, Foxp3, CDS, CD68, CD163, PD-1, and PD-L1 expression levels were evaluated in paraffin-embedded lymphoma tissues to identify their roles in the risk stratification. Eleven factors were identified for further evaluation using analysis of variance, chi-square, and multinomial logistic regression analysis. Results Significant differences in 11 factors （age, Ann Arbor stage, B symptom, ECOG performance status, infiltrating CD8＋ T cells, PD-L1 expression, absolute blood monocyte count, serum lactate dehydrogenase, serum iron, serum albumin, and serum l^2-microglobulin） were observed among patient groups stratified by at least two risk stratification methods [International Prognostic Index （IPI）, revised IPI, and NCCN-IPI models] （P 〈 0.05）. Concordance rates were high （81.4%-100.0%） when these factors were used for the risk stratification. No difference in the risk stratification results was observed with or without the Ann Arbor stage data. Conclusion We developed a convenient and inexpensive tool for use in risk stratification of aggressive B cell lymphomas, although further studies on the role of immune microenvironmental factors are needed.

Everolimus in de novo liver transplant recipients: a systematic review

BACKGROUND： Everolimus has no nephrotoxicity and is used to treat patients with post-liver transplant chronic renal insufficiency. The present systematic review was to evaluate the efficacy and safety of everolimus in de novo liver transplant patients.DATA SOURCES： Randomized controlled trials comparing everolimus for de novo liver transplant in Pub Med, the Cochrane Library, and Science Direct published up to March 31, 2014 were searched by two independent reviewers. Mean differences and 95% confidence interval（95% CI） for renal function, relative risk（RR） and 95% CI for treated biopsy-proven acute rejection（t BPAR）, graft loss, death, neoplasms/tumor recurrence, and adverse events were collected. Meta-analyses were performed with Rev Man version 5.10.RESULTS： A total of four randomized controlled trials covering 1119 cases were included. The meta-analyses revealed that compared with standard exposure of calcineurin inhibitors（CNIs）, everolimus combined with reduced CNIs improved creatinine clearance（calculated with the Cockcroft-Gault formula） by 5.13 m L/min at one year（95% CI： 0.42-9.84; P=0.03）, and decreased t BPAR（RR： 0.56; 95% CI： 0.35-0.90; P=0.02）. Everolimus initiation with CNIs elimination improved glomerular filtration rate（GFR, measured with the modification of diet in renal disease formula） of 10.42 m L/min/1.73 m2（95% CI： 3.44-17.41; P〈0.01） one year after treatment, but in-creased t BPAR（RR： 1.71; 95% CI： 1.15-2.53; P〈0.01）. Everolimus decreased the risk of neoplasms/tumor recurrence after liver transplant（RR： 0.60; 95% CI： 0.34-1.03; P=0.06）, but was associated with greater risk of adverse events which resulted in drug discontinuation（RR： 1.98; 95% CI： 1.49-2.64; P〈0.01）. CONCLUSIONS： Early introduction of everolimus combined with low-dose or no CNI in de novo liver transplant significantly improves renal function one year post treatment. Everolimus combined with low-dose CNI decreases the risk of t BPAR one year after liver transplant, but everolimus administered without CNIs increases t BPAR.

Effect of brain-derived neurotropic factor released from hypoxic astrocytes on gamma-aminobutyric acid type A receptor function in normal hippocampal neurons

Astrocytes can release increased levels of brain-derived neurotrophic factor during cerebral ischemia, but it is unclear whether brain-derived neurotrophic factor affects y-aminobutyric acid type A receptor function in normal neurons. Results from this study demonstrated that y-aminobutyric acid at 100 pmol/L concentration raised the intracellular calcium level in neurons treated with medium from cultured hypoxic astrocytes, and the rise in calcium level could be inhibited by y-aminobutyric acid type A receptor antagonist bicuculline or brain-derived neurotrophic factor receptor antagonist k252a, y-aminobutyric acid type A-gated current induced by 100 IJmol/L y-aminobutyric acid was in an inward direction in physiological conditions, but shifted to the outward direction in neurons when treated with the medium from cultured hypoxic astrocytes, and this effect could be inhibited by k252a. The reverse potential was shifted leftward to -93 mV, which could be inhibited by k252a and Na＋-K＋-CI cotransporter inhibitor bumetanide. Brain-derived neurotrophic factor was released from hypoxic astrocytes at a high level. It shifted the reverse potential of y-aminobutyric acid type A-gated currents leftward in normal neurons by enhancing the function of Na＋-K＋-CI- cotransporter, and caused y-aminobutyric acid to exert an excitatory effect by activating y-aminobutyric acid type A receptor.

Adherence-A concept analysis in the context of cardiac rehabilitation

Objective： To explore and identify the concept of adherence in the context of cardiac rehabilitation. This conceptanalysis will provide a framework for clinical decision-making and intervention to improve patients’ adherence tocardiac rehabilitation programme. Method： Walker and Avant’s framework was used to analysis the concept ofadherence. Results： Adherence is defined as patients collaboration with health care provider, active involvement in thetreatment regimen, and persistence in practice characterized by self-efficacy and relapse-prevention. Defining Attributesof adherence include collaboration relationship; self-efficacy promotion and relapse-prevention. Antecedents ofadherence include health care provider’s prescription, illness perceptions, social-economic and environmental factors.Patients adherence to cardiac rehabilitation programme can improve clinical outcomes. However, there is no standardinstrument to measure adherence. Conclusion： Based on the concept analysis, in order to improve patients’ adherence tocardiac rehabilitation, health care provider should invite patients active involvement in making rehabilitation plan andpromote patients’ self-efficacy and prevention relapse.

Comparative efficacy of oral glucose solution versus non-nutritive sucking for pain relief in neonates during nociceptive procedures： a systematic review

Background and aims： The comparative efficacy of glucose solution （GS） versus non-nutritive sucking （NNS） for pain re- lief in neonate remains controversial. This systematic review was consequently performed to objectively investigate the analgesic effect of Oral GS related to NNS in newborns during nociceptive procedures. Methods： All potential records were searched in PubMed, Web of Science, EMBASE, and the Cochrane Library to capture the randomized controlled trials comparing GS with NNS in terms of pain scores in neonates through January 2017. Two independent investigators screened the identified articles, extracted the data, and assessed the methodological quality of the included studies. All statistical analyses were completed by using Review Manager （RevMan） version 5.3.0. Results： Four studies, involving 248 neonates, were incorporated into these statistical analyses. For reducing pain scores, no statistical difference was detected when GS compared to NNS （4 trials; mean difference [MD], 0.75; 95% confidence interval [CI], -0.77 to 2.27; P = 0.33）. Conclusion： Both the GS and NNS reduced the pain scores in neonates who undergoing Hepatitis B vaccination and venipuncture, but the NNS is more convenience than GS to some extent. Considered the limited evidences, more randomized controlled trials with high-quality, large-scale and appropriate measures time are warranted to further establish the comparative efficacy of these two options.
