Objective:To investigate the effect and potential mechanism of circular RNA-centrosome and spindle pole-associated protein 1 (circ-CSPP1) on the malignant biological behavior of hepatoma cells.Methods:Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the expressions of circ-CSPP1 and microRNA-582-5p (miR-582-5p) in hepatoma cells, and Western blotting was used to detect the expression of karyopherins α2 (KPNA2). HepG2 cells were divided into the circ-CSPP1 overexpression group, the circ-CSPP1 overexpression control group, the si-CSPP1 group, the si-NC group, the si-CSPP1+ miR-582-5p inhibition group, and the si-CSPP1+ miR-582-5p inhibition control group. circ-CSPP1 overexpression plasmid, CSPP1 interfering small RNA, CSPP1 interfering small RNA, miR-582-5p inhibition sequence and negative control were transfected respectively in these groups. Cell proliferation in each group was detected by 5-acetylene-2'-deoxyuridine (Edu), invasion ability was detected by Transwell assay, and the binding of circ-CSPP1 and KPNA2 to miR-582-5p was verified by dual-luciferase assay. In the si-CSPP1 group, HepG2 cells transfected with si-CSPP1 lentivirus were subcutaneously injected into the back of nude mice ( n=12), and in the si-NC group, HepG2 cells transfected with negative control lentivirus ( n=12) were injected. The tumor mass, volume, circ-CSPP1 and KPNA2 were detected. Results:In the circ-CSPP1 overexpression group, the relative expression of circ-CSPP1 was (1.68±0.17), the expression of KPNA2 was (1.52±0.16), and the number of invasive cells in the 100-fold field of view was (128.4±13.5), which were all higher than those in the circ-CSPP1 overexpression control group [(1.25±0.16), (1.24±0.15), (128.4±13.5)], while the expression of miR-552-5p was lower than that in the circ-CSPP1 overexpression control group [(0.96±0.11) vs (1.31±0.15)]; The relative expression of circ-CSPP1 in the si-CSPP1 group was (1.02±0.13), KPNA2 was (0.74±0.09), and the number of invasive cells was (53.5±6.7), which were lower than those in the si-NC group [(1.28±0.14), (1.22±0.13), (74.6±8.3)], while the expression of miR-582-5p was higher than that in the si-NC group [(1.71±0.18) vs (1.32±0.14)]; The expression of circ-CSPP1 and KPNA2 and the number of invasion cells in the si-CSPP1+ miR-582-5p inhibition group was higher than that in the si-CSPP1+ miR-582-5p inhibition control group, and the differences were statistically significant (all P<0.05). The results of cell proliferation were consistent with those of invasion. The dual-luciferase gene report showed that, compared with the miR-NC group, the relative luciferase activity in HepG2 cells co-transfected with circ-CSPP1-WT or KPNA2-WT wild-type reporter vectors in the miR-882-5p mimic group decreased [(0.46±0.05) vs (1.03±0.11), (0.42±0.03) vs (1.01±0.09)]. The differences were all statistically significant (both P<0.05). However, there was no statistically significant difference in the relative luciferase activity in HepG2 cells co-transfected with the circ-CSPP1-MUT or KPNA2-MUT mutant reporter vectors (both P>0.05). The tumor weight, volume and circ-CSPP1 and KPNA2 expressions in tumor tissue of nude mice in the si-CSPP1 group were all lower than those in the si-NC group, and the expression of miR-582-5p was higher than that in the si-NC group. The differences were statistically significant (all P<0.05). Conclusion:Inhibition of circ-CSPP1 suppressed the malignant biological behavior of hepatoma cells and tumor growth by upregulating miR-582-5p and downregulating KPNA2.

Objective:To explore the application value of the "Dual-Wing" traction technique in the medial & head lateral laparoscopic left hemicolectomy with radical resection.Methods:The "Dual-Wing " traction technique is based on the theory of mesenteric anatomy. The assistant lifts the proper mesentery of the digestive tract to be resected or the adjacent mesenteric tissue connected to it,thereby elevating the target organ and its mesentery as a whole away from the mesenteric bed. By utilizing the tension transmission between the proper mesenteries of adjacent organs to create counter-tension,the surgeon's operative actions are always maintained along the line of maximum counter-tension.After incising the mesenteric fusion line,this technique assists the surgeon in entering the fusion plane. A descriptive case series study method was adopted to retrospectively analyze the clinical and pathological data of 37 colorectal cancer patients who underwent laparoscopic left hemicolectomy with the "Dual-Wing" traction technique via a medial and cephalad approach, performed by the Department of Gastrointestinal Surgery at Dongjie Campus of the First Hospital of Quanzhou, Fujian Medical University, from May 2023 to November 2023.Results:All patients successfully underwent laparoscopic left hemicolectomy via the medial & head lateral approach using the "Dual-Wing" traction technique.The surgery adhered to the principles of total mesocolic excision and safely mobilized the left colon and its mesentery from the correct anatomical plane. In the entire group of patients,there were 14 males and 23 females; the mean operative time was 94.1±18.3 minutes; the mean intraoperative blood loss was 9.8±5.4 ml; the mean number of lymph nodes dissected was 18.1±3.9; the mean number of positive lymph nodes was 1.4±1.6; the pathological specimen resection margin grading was Grade A in 29 cases, Grade B in 8 cases, and no Grade C cases; the tumor TNM staging was Stage I in 3 cases, Stage IIA in 7 cases, Stage IIB in 6 cases, Stage IIIA in 2 cases, Stage IIIB in 15 cases, and Stage IIIC in 4 cases; the mean time to first flatus postoperatively was 35.7±7.5 hours; the mean length of hospital stay was 9.1±1.7 days. There were no intraoperative injuries to the pancreas or spleen. Postoperative complications occurred in 3 cases. No anastomotic leakage was observed in the entire group, and there were no deaths following the surgery.Conclusion:The application of the "Dual-Wing" traction technique to establish a stable surgical scenario can significantly reduce the demands on the assistant. It is conducive to maintaining mesenteric tension and fully exposing the surgical field. It also allows for the rapid identification and maintenance of the correct anatomical plane. For colorectal cancer patients, the surgery is safe and feasible, with satisfactory short-term therapeutic effects.

OBJECTIVE To investigate the efficacy and safety of tirofiban for early neurological deterioration in patients with acute ischemic stroke. METHODS A total of 126 patients with early neurological deterioration of acute ischemic stroke who were admitted to the Department of Neurology， Heji Hospital Affiliated to Changzhi Medical College from January 2022 to December 2023 were selected and divided into observation group and control group according to random number table method， with 63 cases in each group. All patients received standardized treatment such as lipid-lowering and blood pressure-lowering therapy. Based on the standard treatment， patients in the control group additionally took Aspirin enteric-coated tablets 100 mg+Clopidogrel bisulfate tablets 75 mg orally （once a day， for 14 consecutive days）. The patients in the observation group received Tirofiban hydrochloride and sodium chloride injection based on the standardized treatment [first intravenous infusion of 0.40 μg/（kg·min） for 30 min， and then continuous intravenous infusion of 0.10 μg/（kg·min） for 47.5 h]； subsequently， patients were given Aspirin enteric-coated tablets （100 mg） and Clopidogrel bisulfate tablets （75 mg） once a day for 14 consecutive days. The clinical efficacy， the National Institutes of Health Stroke Scale （NIHSS） score， modified Rankin Scale （mRS） score， and hemorheological indexes before and after treatment were compared between the two groups， and the adverse reactions were recorded. RESULTS The total effective rate （87.30%） of the observation group was significantly higher than that of the control group （71.43%） （P＜0.05）. NIHSS scores of the two groups at 1st， 7th and 14th day after treatment， the mRS score at 90th day after treatment， and the platelet aggregation rate， whole blood viscosity， plasma viscosity and fibrinogen at 14th day after treatment were significantly lower than those before treatment in the same group， and the observation group was significantly lower than the control group at the same period （P＜0.05）. The total incidences of adverse reactions such as nausea， headache， fever， gastrointestinal bleeding， oral and nasal mucosal bleeding and thrombocytopenia in both groups of patients were 28.57% respectively， with no statistically significant difference （P＞0.05）. CONCLUSIONS For patients with early neurological deterioration in acute ischemic stroke， the addition of tirofiban can accelerate the recovery of neurological function， improve blood hyperviscosity and platelet aggregation， and improve the prognosis of patients with good safety.

Objective:To explore the feasibility of joint screening of the two primary immunodeficiency diseases [severe combined immunodeficiency (SCID) and X-linked agammaglobulinemia(XLA)] and spinal muscular atrophy(SMA) in newborns by multiplex real-time quantitative PCR technology, and to provide evidence for early screening, diagnosis and treatment of children.Methods:Cross-sectional study. From July 2021 to January 2023, a total of 103 240 dry blood spots samples of newborns were collected which were delivered to Neonatal Disease Screening Center of Zhejiang by cold chain transportation. The concentrations of the T cell receptor excision ring (TREC), Kappa deletion of the recombinant excision loop (KREC), and exon 7 deletion of Survival Motor Neuron 1 (SMN1) gene in dry blood spots were simultaneously detected by multiplex real-time fluorescence quantitative PCR, taken ribonuclease P/MRP 30 000 subunits (RPP30) as an internal reference gene. The positive newborns were further diagnosed by other laboratory tests and gene sequencing was taken as gold standard. Children samples from 1 case of SCID, 3 cases of XLA and 2 cases of SMA were used for positive verification. The correlation between detected concentration of TREC/KREC and basic information in newborns were analyzed. The differences among groups for each factor were analyzed.Results:One case of SCID, 2 cases of XLA, 9 cases of SMA and 7 cases of other genetic diseases (4 cases of DiGeorge syndrome, 1 case of trisomy 21 syndrome, 1 case of Noonan syndrome and 1 case of super male syndrome) were identified by multiplex real-time fluorescence quantitative PCR. The positive predictive values of screening neonatal SCID, XLA and SMA were 2.44% (1/41), 2.78% (2/72) and 9/9 respectively. Taking the samples from clinically diagnosed 1 case of SCID, 3 cases of XLA and 2 cases of SMA as positive validation samples, which were all identified. The detected results of TREC/KREC correlated with time of blood collection, sex, weight, gestational age and delivery mode of newborns, whose r values were 0.162/0.187, 0.066/0.032, 0.045/0.042, ?0.015/?0.088 and 0.014/0.068 respectively (all P<0.05). Conclusions:Relying on current neonatal screening platform in Zhejiang, it is feasible to screen jointly two kinds of primary immunodeficiency diseases and spinal muscular atrophy in newborns by multiple real-time fluorescence quantitative PCR technology.

Fluorine, as one of the important trace elements, has multiple physiological functions and participates in body metabolism. Moderate intake of fluoride is beneficial for human health, while excessive fluoride can lead to dental fluorosis, skeletal fluorosis, and multi-organ damage. Typical symptoms of skeletal fluorosis include bone sclerosis, osteomalacia, osteoporosis, and degenerative changes in articular cartilage. The pathological basis for skeletal changes in fluorosis involves enhanced osteogenesis and accelerated bone turnover, which are comprehensively regulated by multiple signaling pathways. Although the etiology of skeletal fluorosis has been determined, its pathogenic mechanisms remain inconclusive. In recent years, researchers have extensively investigated the signaling pathways involved in skeletal fluorosis development, including Notch, phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR), Wnt/β-catenin, Hedgehog, nuclear factor κB (NF-κB), parathyroid hormone (PTH), and insulin signaling pathways, as well as their interactive networks. This article summarizes and reviews the recent research findings, aiming to provide a theoretical foundation for comprehensively understanding the pathogenic mechanisms of skeletal fluorosis and offer insights for scientific prevention of skeletal fluorosis.
