OBJECTIVE: To systematically evaluated clinical efficacy of Kirschner's needle and elastic intramedullary nail fixation in treating proximal humeral fractures in children by Meta-analysis. METHODS: Literature on the treatment of proximal humeral fractures in children with Kirschler needles and elastic intramedullary nails published on Wanfang, VIP, CNKI and China biology medicine (CBM), PubMed, Embase, and Web of Science databases were searched from the establishment of databases to October, 2023. Literature extraction, management and data entry were performed by Endnote X9 and Excel 2019, and Meta-analysis was conducted by RevMan 5.3 software. The operation time, hospital stay, fracture healing time, shoulder joint extension range of motion, disabilities of arm, shoulder and hand(DASH) questionnaire score, Neer score or Constant-Murley score and complications were compared between two groups. RESULTS: A total of 7 literatures were included, 1 was prospective study, 6 were retrospective cohort study. There were 521 children, 264 children in Kirschner wire group and 257 children in elastic intramedullary nail fixation group. The results of Meta analysis showed operation time[WMD=-12.61, 95%CI(-24.89, -0.33), P=0.04], fracture healing time[WMD=-0.26, 95%CI(-0.49, -0.02), P=0.03], total complication rate [OR=6.83, 95%CI(3.33, 14.01), P<0.001], nail tract infection rate[OR=6.77, 95%CI(1.72, 26.69), P=0.006] and displacement fracture rate[OR=3.57, 95%CI(1.35, 9.44), P=0.01] between two groups had statistically differences(P>0.05), while there were no statistically significant difference in comparison of hospital stay, shoulder joint extension range of motion, DASH, Neer score, Constant-Murley score, and incidence of skin irritation between two groups (P>0.05). CONCLUSION Kirschner's needle internal fixation has a short operation time and simple operation, but it has a higher incidence of complications compared with elastic nail internal fixation technique. In terms of efficacy and safety, elastic intramedullary nail fixation is one of the options for the treatment of proximal humeral fractures in children.

Objective: To explore the regulatory mechanism of NUDT5 in glioblastoma multiforme (GBM). Methods: GEPIA database was used to predict the expressions of NUDT5 and tripartite motif family proteins 47 (TRIM47) in GBM patients. RT-qPCR and Western blot analyses were performed to examine NUDT5 expression in GBM cells. LN-229 cell proliferation, migration as well as invasion were estimated by CCK- 8, colony formation, wound healing, and Transwell assays following interference with NUDT5. ECAR assay, L-lactic acid kit, glucose detection kit, and ATP detection kit were applied for the detection of glycolysis-related indexes. Co-immunoprecipitation experiment was carried out to verify the relationship between NUDT5 and TRIM47. Results: GEPIA database showed that NUDT5 expression was significantly increased in GBM patients. Inhibiting the expression of NUDT5 in GBM cells significantly suppressed the viability, proliferation, invasion, migration, and glycolysis of GBM cells. Moreover, TRIM47 was highly expressed in GBM cells and interacted with NUDT5. Overexpression of TRIM47 partially reversed the inhibitory effect of NUDT5 downregulation on the proliferation, metastasis, and glycolysis of GBM cells. Conclusions: NUDT5 promotes the growth, metastasis, and Warburg effect of GBM cells by upregulating TRIM47. Both NUDT5 and TRIM47 can be used as targets for GMB treatment.

OBJECTIVE: To explore the anti-inflammatory effects of ethyl lithospermate in lipopolysaccharide (LPS)-stimulated RAW 264.7 murine-derived macrophages and zebrafish, and its underlying mechanisms. METHODS: 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazoliumbromide (MTT) assays were performed to investigate the toxicity of ethyl lithospermate at different concentrations (12.5-100 µ mol/L) in RAW 264.7 cells. The cells were stimulated with LPS (100 ng/mL) for 12 h to establish an inflammation model in vitro, the production of pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor α (TNF-α) were assessed by enzyme linked immunosorbent assay (ELISA). Western blot was used to ascertain the protein expressions of signal transducer and activator of transcription 3 (STAT3), nuclear factor kappa B (NF-κB) p65, phospho-STAT3 (p-STAT3, Tyr705), inhibitor of NF-κB (IκB) α, and phospho-I κB α (p-IκB α, Ser32), and confocal imaging was used to identify the nuclear translocation of NF-κB p65 and p-STAT3 (Tyr705). Additionally, the yolk sacs of zebrafish (3 days post fertilization) were injected with 2 nL LPS (0.5 mg/mL) to induce an inflammation model in vivo. Survival analysis, hematoxylin-eosin (HE) staining, observation of neutrophil migration, and quantitative real-time polymerase chain reaction (qRT-PCR) were used to further study the anti-inflammatory effects of ethyl lithospermate and its probable mechanisms in vivo. RESULTS: The non-toxic concentrations of ethyl lithospermate have been found to range from 12.5 to 100 µ mol/L. Ethyl lithospermate inhibited the release of IL-6 and TNF-α(P<0.05 or P<0.01), decreased IκBα degradation and phosphorylation (P<0.05) as well as the nuclear translocation of NF-κB p65 and p-STAT3 (Tyr705) in LPS-induced RAW 264.7 cells (P<0.01). Ethyl lithospermate also decreased inflammatory cells infiltration and neutrophil migration while increasing the survival rate of LPS-stimulated zebrafish (P<0.05 or P<0.01). In addition, ethyl lithospermate also inhibited the mRNA expression levels of of IL-6, TNF-α, IκBα, STAT3, and NF-κB in LPS-stimulated zebrafish (P<0.01). CONCLUSION Ethyl lithospermate exerts anti-Inflammatory effected by inhibiting the NF-κB and STAT3 signal pathways in RAW 264.7 macrophages and zebrafish.

Lysine acetyltransferase 5 (KAT5), a member of the MYST family, can participate in cellular processes such as transcription, DNA repair, differentiation and signal transduction by acetylating different substrates. The role of KAT5 cannot be replaced by other MYST family members, and the knockout of KAT5 can directly lead to apoptosis, indicating that KAT5 may be located in the upstream of physiological signaling pathways in cells and play an extremely important and unique role. Therefore, the changes in KAT5 expression are very likely to lead to the occurrence and development of tumors. Previous studies have found that KAT5 is downregulated in breast cancer, melanoma, and lung cancer, and is considered a tumor suppressor in these tumors. However, in recent years, studies have found that KAT5 can be either highly or lowly expressed in breast cancer, liver cancer, melanoma, prostate cancer, lung cancer and other tumors. On the premise of high KAT5 expression, KAT5 can play a tumor-promoting role. While on the premise of low KAT5 expression, KAT5 can also play as a tumor suppressor. With further decrease of KAT5 expression, its tumor suppressive effect is weakened, which may lead to the occurrence and development of tumors. In addition, KAT5 has also been found to be differentially expressed in osteosarcoma, thyroid cancer, glioblastoma, colorectal cancer and other tumors, and the differential expression of KAT5 is closely related to the proliferation, metastasis, apoptosis, drug and radiotherapy resistance of tumor cells. Therefore, KAT5 is one of the potential tumor therapeutic targets. Here, we summarize the expression of KAT5 in tumors and the tumor-suppressing or tumor-promoting signaling pathways involved in the corresponding expression in recent years, hoping to provide new inspiration and reference for tumor treatment and prognosis monitoring.

Objective: To investigate the efficacy and safety of percutaneous closure of ventricular septal rupture (VSR) after acute myocardial infarction (AMI) and the risk factors of all-cause mortality at 30 days after operation. Methods: This is a retrospective case series study. A total of 69 patients with post-AMI VSR, underwent percutaneous closure of VSR from October 2013 to May 2020 in Department of Cardiology of Henan Provincial People's Hospital and Department of Cardiology of Central China Fuwai Hospital, were included. Patients were divided into survival group (53 cases) and non-survival group (16 cases) according to the status at 30 days after operation. Clinical data were collected and analyzed during hospitalization. Telephone follow-up was performed 30 days after operation. The primary safety endpoint was occlusion failure and all-cause mortality at 30 days post operation. The secondary safety endpoint was the operation related or non-operation related complications. Efficacy endpoint included NYHA classification of cardiac function, index measured by right heart catheterization and echocardiography. Multivariate logistic regression was performed to analyze the risk factors of all-cause mortality at 30 days after operation. Results: A total of 69 patients, aged 67 (64, 71) years, including 42 women (60.9%), were enrolled in this study. All-cause death occurred in 16 patients (23.2%), including 13 in-hospital death and 3 death during follow-up. There were 4 cases of closure failure (5.8%). Among the 65 patients with successful closure, 12 (18.5%) experienced operation-related complications, among which 8 (12.3%) experienced valve injury. The mortality was significantly higher in patients with operation-related complications than that in patients without operation-related complications (41.7% (5/12) vs. 13.2% (7/53), P = 0.022). One case received percutaneous closure of VSR and PCI, this patient experienced new-onset AMI immediately post procedure and died thereafter (1.5%). One case (1.5%) developed multiple organ failure and 2 cases (3.1%) developed gastrointestinal bleeding post operation. All of the 65 patients with successful occlusion completed postoperative echocardiography, 56 patients completed cardiac function assessment at discharge, and 53 patients who survived up to 30 days post discharge completed clinical follow up by telephone. The NYHA cardiac function at discharge and 30 days after operation were significantly improved as compared to that before operation (P<0.001), the ratio of NYHA Ⅰ and Ⅱ patients was significantly higher post operation at these two time points as compared to baseline level (76.8% (43/56) vs. 23.1% (15/65), P<0.001, 77.4% (41/53) vs. 23.1% (15/65), P<0.001). The pulmonary circulation/systemic circulation blood flow ratio (Qp/Qs), pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic diameter (LVDd) were decreased, aortic systolic pressure (ASP) and left ventricular ejection fraction (LVEF) were increased post operation (P<0.05). Multivariate logistic regression analysis showed that WBC>9.8×10⁹/L (OR=20.94, 95%CI 1.21-362.93, P=0.037) and NT-ProBNP>6 000 ng/L (OR=869.11, 95%CI 2.93-258 058.34, P=0.020) were the independent risk factors of mortality at 30 days. Conclusions: Percutaneous closure in VSR after AMI is safe and effective. The increase of WBC and NT-ProBNP are the independent risk factors of all-cause mortality at 30 days after operation.

Objective: To compare the time of the recovery of neutrophils or leukocytes by pegylated recombinant human granulocyte stimulating factor (PEG-rhG-CSF) or common recombinant human granulocyte stimulating factor (rhG-CSF) in the myelosuppressive phase after induction chemotherapy in newly diagnosed acute myeloid leukemia (AML) patients. At the same time, the incidences of infection and hospitalization were compared. Methods: A prospective randomized controlled trial was conducted in patients with newly diagnosed AML who met the enrollment criteria from August 2014 to December 2017. The patients were randomly divided into two groups according to a 1:1 ratio: PEG-rhG-CSF group and rhG-CSF group. The time of neutrophil or leukocyte recovery, infection rate and hospitalization interval were compared between the two groups. Results: 60 patients with newly diagnosed AML were enrolled: 30 patients in the PEG-rhG-CSF group and 30 patients in the rhG-CSF group. There were no significant differences in age, chemotherapy regimen, pre-chemotherapy ANC, WBC, and induction efficacy between the two groups (P>0.05) . The median time (range) of ANC or WBC recovery in patients with PEG-rhG-CSF and rhG-CSF were 19 (14-35) d and 19 (15-26) d, respectively, with no statistical difference (P=0.566) . The incidences of infection in the PEG-rhG-CSF group and the rhG-CSF group were 90.0%and 93.3%, respectively, and there was no statistical difference (P=1.000) . The median days of hospitalization (range) was 20.5 (17-49) days and 21 (19-43) days, respectively, with no statistical difference (P=0.530) . Conclusions: In AML patients after induction therapy, there was no significant difference between the application of PEG-rhG-CSF and daily rhG-CSF in ANC or WBC recovery time, infection incidence and hospitalization time.

OBJECTIVETo explore the effect of postoperative initial neck stem angle on the treatment of proximal humeral fractures with locking plate.

METHODSFrom June 2014 to Septembetr 2016, 62 patients with proximal humeral fractures underwent internal fixation with locking plates were retrospectively analyzed, including 29 males and 33 females with an average age of(55.95±9.48) years old ranging from 34 to 74 years old. According to the difference of the initial neck stem angle, the patients were divided into three groups, 15 patients in the varus group had less than 127° postoperative initial neck-shaft angle, 36 patients in the normal group had 127° to 145° postoperative initial neck-shaft angle, 11 patients in the valgus group had more than 145° postoperative initial neck-shaft angle. The operating time, fracture healing time, complications, the visual analogue scale(VAS) and shoulder functional Neer scores among three groups were compared for analysis.

RESULTSAll 62 patients were followed up for 17.2 months(ranged 12 to 38 months). Operative time, fracture healing time and VAS were(2.37±0.59) hours, (3.99±0.48) months and(3.67±2.02) points in the varus group;(2.60±0.49) hours, (3.78±0.49) months and(3.22±2.06) points in the normal group;(2.75±0.39) hours, (3.82±0.42) months and (4.09±1.58) points in the valgus group. There was no statistical difference in operating time, fracture healing time and VAS among these groups(>0.05). The Neer score(87.14±6.48) in the normal group and(84.31±9.05) in the valgus group was significantly better than(75.93±9.77) in the varus group (<0.05). Among them, 4 cases occurred complications in the varus group;2 cases in the normal group;while no complication occurred in the valgus group.

CONCLUSIONSThe internal fixation with locking plates of the proximal humerus fractures with postoperative initial neck-shaft angle more than 127° can reduce complications, improve shoulder function and allow for better postoperative outcome.
