Aim To investigate the expression levels of cytoplasmic FMR1-interacting protein-1(CYFIP1)in colorectal cancer and assess the impact of CYFIP1 interaction on the proliferation and apoptosis of colorec-tal cancer cell HT29,along with its potential mecha-nisms.Methods Immunohistochemistry was em-ployed to assess CYFIP1 expression in 32 colorectal cancer tissues and adjacent tissues.Coexpressed genes were identified using the GEPIA2 website to predict potential correlations and binding sites.Following the construction of a siRNA-CYFIP1,alterations in cell proliferation,apoptosis,and levels of apoptosis-related proteins were evaluated through CCK-8 assay,Hoechst 33342/PI double staining assay,and Western blot a-nalysis,respectively.Results The immunohisto-chemical findings revealed a significantly elevated level of CYFIP1 expression in colorectal cancer tissues com-pared to paracancer tissues(P＜0.05).The expres-sion of CYFIP1 did not show any correlation with age and gender,but exhibited associations with TNM stage and lymph node metastasis(P＜0.05).A conserved TP53 binding site was predicted in the 3kbps DNA re-gion upstream of the CYFIP1 gene using GEPIA2,JASPAR databases,and rVista 2.0 promoter prediction software.Following transfection of HT29 cells with siRNA-CYFIP1,the clonogenesis and proliferation of cells significantly decreased(P＜0.05).Additional-ly,the levels of cleaved caspase-3 were elevated,while the expression levels of caspase-3 and Bcl-2 were reduced after transfection with siRNA-CYFIP1(P＜0.05),which might be related to the interaction be-tween CYFIP1 and TP53.Conclusions The upregu-lation of CYFIP1 in colorectal cancer is associated with TNM stage and lymph node metastasis.Upon silen-cing,CYFIP1 demonstrates the ability to suppress pro-liferation in HT29 cells and modulate the expression of apoptotic proteins.

OBJECTIVE: To observe the efficacy of chimeric antigen receptor T cell (CAR-T) in the treatment of children with refractory/recurrent B acute lymphocytic leukemia (B-ALL). METHODS: Thirty-two patients with r/r B-ALL were treated by CAR-T, the recurrence and death respectively were the end point events to evaluate the efficacy and safety of CAR-T. RESULTS: The median age of the patients was 7.5 (2-17.5) years old; 40 times CAR-T were received in all patients and the median number of CAR-T was 0.9×107/kg; efficacy evaluation showed that 2 cases died before the first evaluation. Thirty patients showed that 3, 6, and 9-moth RFS was (96.3±3.6)%, (81.4±8.6)% and (65.3±12.5)%, respectively, while 3, 6, and 9-month OS was all 100%, and 12, 24-month OS was (94.7±5.1)% and (76±12.8)%. BM blasts≥36% before reinfusion and ferritin peak≥2 500 ng/ml within two weeks of CAR-T cell reinfusion were associated with recurrence. Adverse reactions mainly included cytokine release syndrome (CRS) and CART-cell-related encephalopathy syndrome (CRES), CRS appeared in 26 patients within a week of CAR-T cell reinfusion. CRES reaction was detected in 12 patients. Eighteen patients received intravenous drip of tocilizumab, among them, 12 combined with glucocorticoid. CRS and CRES reactions were relieved within one week after treatment. Hormone dosage was related to the duration of remission in patients, and the cumulative dose of methylprednisolone≥8 mg/kg showed a poor prognosis. CONCLUSION CAR-T is a safe and effective treatment for r/r B-ALL, most CRS and CRES reactions are reversible. BM blasts ≥36% before reinfusion and cumulative dose of methylprednisolone ≥8 mg/kg after reinfusion both affect the therapeutic effect. Ferritin≥2 500 ng/ml within two weeks after reinfusion is related to disease recurrence and is an independent prognostic risk factor.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

Objective To characterize the species of invasive Pomacea snails that were discovered for the first time in Shandong Province. Methods Pomacea snails samples were collected in the field of Jining City, Shandong Province on October 2021 for morphological identification. Pomacea snails were randomly sampled and genomic DNA was extracted from foot muscle tissues of Pomacea snails for multiplex PCR amplification. The PCR amplification product was sequenced. Then, the sequence was aligned and a phylogenetic tree was created using the software MegAlign 7.1.0. In addition, Angiostongylus cantonensis infection was detected in Pomacea snails with the lung microscopy. Results A total of 104 living Pomacea snails were collected, and all were characterized as Pomacea spp. based on morphological features. Of 12 randomly selected adult Pomacea snails, multiplex PCR assay and sequencing identified eleven snails as P. canaliculata and one as P. maculata. No A. cantonensis infection was detected in 104 Pomacea snails. Conclusion This is the first report of invasive Pomacea snails in Shandong Province, where P. canaliculata and P. maculata are found.

BACKGROUND: Scoliosis secondary to neurofibromatosis type 1 (NF1) in children aged <10 years is an important etiology of early-onset scoliosis (EOS). This study was performed to investigate the curve evolution of patients with EOS secondary to NF1 undergoing bracing treatment and to analyze high-risk indicators of rapid curve progression. METHODS: Children with EOS due to NF1 who underwent bracing treatment from 2010 to 2017 were retrospectively reviewed. The angle velocity (AV) at each visit was calculated, and patients with rapid curve progression (AV of >10°/year) were identified. The age at modulation and the AV before and after modulation were obtained. Patients with (n = 18) and without rapid curve progression (n = 10) were statistically compared. RESULTS: Twenty-eight patients with a mean age of 6.5 ± 1.9 years at the initial visit were reviewed. The mean Cobb angle of the main curve was 41.7° ± 2.4° at the initial visit and increased to 67.1° ± 8.6° during a mean follow-up of 44.1 ± 8.5 months. The overall AV was 6.6° ± 2.4°/year for all patients. At the last follow-up, all patients presented curve progression of >5°, and 20 (71%) patients had progressed by >20°. Rapid curve progression was observed in 18 (64%) patients and was associated with younger age at the initial visit and a higher incidence of modulation change during follow-up (t = 2.868, P = 0.008 and <0.001, respectively). The mean AV was 4.4° ± 1.2°/year before modulation and 11.8° ± 2.7°/year after modulation (t = 11.477, P < 0.010). CONCLUSIONS Curve progression of >10°/year is associated with younger age at the initial visit, and modulation change indicated the occurrence of the rapid curve progression phase.

Objective:To observe the effect of extracorporeal shock wave therapy on tendon adhesion in late period after hand tendon repair. Methods:From July, 2017 to December, 2018, 40 patients with tendon adhesion after hand tendon repair more than three months were collected. They were randomly divided into control group (n = 20) and experimental group (n = 20). Two groups received routine therapy, and the experimental group added extracorporeal shock wave therapy. Before and two months after treatment, the total active movement (TAM) of the fingers and the grip strength were messured. Results:There was no significant difference in TAM of the fingers and the grip strength before treatment (P > 0.05). After treatment, TAM of the fingers and the grip strength significantly increased (|t| > 10.284,P < 0.001), and were higher in the experimental group than in the control group (t > 0.386,P < 0.001). Conclusion:Extracorporeal shock wave therapy could facilitate to improve the tendon slippage and hand function in patients with tendon adhesion after hand tendon repair.

Background: Right upper lobectomy (RUL) for lung cancer with different dissecting orders involves the most vari-able anatomical structures, but no studies have analyzed its effects on postoperative recovery. This study compared the conventional surgical approach, VAB (dissecting pulmonary vessels first, followed by the bronchus), and the alter-native surgical approach, aBVA (dissecting the posterior ascending arterial branch first, followed by the bronchus and vessels) on improving surgical feasibility and postoperative recovery for lung cancer patients. Methods: According to the surgical approach, consecutive lung cancer patients undergoing RUL were grouped into aBVA and VAB cohorts. Their clinical, pathologic, and perioperative characteristics were collected to compare periop-erative outcomes. Results: Three hundred one patients were selected (109 in the aBVA cohort and 192 in the VAB cohort). The mean operation time was shorter in the aBVA cohort than in the VAB cohort (164 vs. 221 min, P < 0.001), and less blood loss occurred in the aBVA cohort (92 vs. 141 mL, P < 0.001). The rate of conversion to thoracotomy was lower in the aBVA cohort than in the VAB cohort (0% vs. 11.5%, P < 0.001). The mean duration of postoperative chest drainage was shorter in the aBVA cohort than in the VAB cohort (3.6 vs. 4.5 days, P = 0.001). The rates of postoperative complica-tions were comparable (P = 0.629). The median overall survival was not arrived in both cohorts (P > 0.05). The median disease-free survival was comparable for all patients in the two cohorts (not arrived vs. 41.97 months) and for patients with disease recurrences (13.25 vs. 9.44 months) (both P > 0.05). The recurrence models in two cohorts were also comparable for patients with local recurrences (6.4% vs. 7.8%), distant metastases (10.1% vs. 8.3%), and both (1.8% vs. 1.6%) (all P > 0.05). Conclusions: Dissecting the right upper bronchus before turning over the lobe repeatedly and dissecting veins via the aBVA approach during RUL would promote surgical feasibility and achieve comparable postoperative recovery for lung cancer patients.

Objective To evaluate the association of cervical cancer and the G/C single nucleotide polymorphism at codon 72 in p53 gene exon -4 in Chinese population.Methods Literatures were searched in CNKI,VIP,CBM, PubMed,EMBase,the Cochrane Library (Issue 1,2015),WanFang Data Database (1980—2015)with computer. Results Thirteen studies involving 1 780 cervical cancer patients and 1 5 17 healthy volunteers were included.According to the situation of the HPV infection in research object,thirteen studies were divided into two subgroups.The results of meta-analyses in the subgroup of non-HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.980,95%CI:0.558 -1.723).The allele G showed no increased relative risk compared to the allele C (OR=1.070,95%CI:0.789-1.449)The results of meta-analyses in the subgroup of HPV infection showed that the Chinese women having the genotype G/G presented no increased relative risk compared to that with the genotype C/C(OR=0.891,95%CI:0.213 -3.722).The allele G showed no increased relative risk compared to the allele C (OR =0.981,95%CI:0.493 -1.951 ).Conclusion This meta -analysis demonstrates that G/C single nucleotide polymorphism at codon 72 in p53 gene exon-4 were not associated with cervical cancer in Chinese women.

OBJECTIVETo investigate the effect of enteral nutrition(EN) on liver function and inflammatory response after abdominal operation in patients with liver dysfunction.

METHODSA prospective multicenter study was conducted. Patients requiring EN for at least 5 days after abdominal surgery with at least 1 abnormal liver function index were included. After operations, EN suspensions(TPF-FOS) were administered for 5 days after the return of bowel function with targeted content of 125.52 kJ(30 kcal)·kg(-1)·d(-1) maintained for a minimum of 3 days. Levels of serum pre-albumin, C-reaction protein(CRP), and liver function index were measured and the incidence of systemic inflammatory response syndrome(SIRS) was recorded before operation and 6 days after EN. Occurrence of gastrointestinal discomfort was monitored during the treatment.

RESULTSNo statistically significant difference was found in pre-albumin between preoperative level and post-EN level[(175.94±71.79) mg/L vs.(192.22±91.26) mg/L, P=0.162]. Patients with abnormal level of γ-glutamyl transpeptidase were less after EN compared to the preoperative period(30 vs. 40, P=0.041), as was total bilirubin (3 vs. 9, P=0.034). No significant differences in other indices of liver function were found. Total bilirubin and direct bilirubin decreased after EN support(P=0.000 and P=0.015, respectively). CRP was notably reduced after EN support [(48.74±65.16) mg/L vs.(25.79±23.63) mg/L, P=0.009] and the incidence of SIRS largely declined after EN support(19.0% vs. 10.3%, P=0.059). The incidence of gastrointestinal discomfort was 22.4% on postoperative day 1 and declined to 19.0% on postoperative day 5.

CONCLUSIONFor patients with liver dysfunction, enteral nutrition support with TPF-FOS after abdominal operation can reduce inflammatory response, improve liver function, and maintain serum protein level.
