Objective To analyze the clinical characteristics and risk factors of extreme thrombocytosis caused by piperacillin sodium and tazobactam sodium injection, and provide reference for medical treatment and pharmaceutical care of such patients. Methods Extreme thrombocytosis of a patient treated with piperacillin sodium and tazobactam sodium injection was found by clinical pharmacists, who participated in clinical diagnosis and treatment by analyzing of the adverse drug reaction, optimization of the medical treatment and pharmaceutical care. Results After correlation analysis, the patient's extreme thrombocytosis was likely to be an adverse reaction caused by the piperacillin sodium and tazobactam sodium injection. The medication was immediately discontinued, and antiplatelet therapy with aspirin was administered. Two weeks later, the patient's platelet count had significantly decreased compared to before. Conclusion Clinical pharmacists participated in patients’ clinical diagnosis and treatment, carried out pharmaceutical care and assisted physicians in adjusting treatment plans, which ensured the safety and effectiveness of patients' clinical drug therapy.

Mass spectrometry imaging （MSI） is an emerging molecular imaging technique that combines high spatial resolution and the ability to acquire molecular information. This technology can directly obtain spatial distribution maps of metabolites, proteins, lipids and other molecules in tumor tissues, reveal the abnormal molecular changes during the occurrence and development of liver cancer, and make up for the deficiency of information at the molecular level in traditional imaging （such as CT, MRI）. In liver cancer research, MSI has demonstrated unique advantages and application potential in early diagnosis and screening, precise classification, tumor heterogeneity analysis, and exploration of molecular mechanisms. The principle characteristics of MSI technology and its latest progress in the early diagnosis, classification and molecular mechanism research of liver cancer were reviewed, and the current challenges and future development directions were discussed, which aimed to provide a new perspective and theoretical basis for an in-depth understanding of the pathological mechanism of liver cancer and promoted its precise diagnosis and treatment.

OBJECTIVE To evaluate the efficacy and safety of cadonilimab plus chemotherapy in patients with advanced gastric adenocarcinoma or adenocarcinoma of gastroesophageal junction （AEG） with intermediate， low， or no human epidermal growth factor receptor 2 （HER2） expression. METHODS Patients with advanced gastric adenocarcinoma or AEG with intermediate， low， or no HER2 expression who were treated at Liaoning Cancer Hospital between October 1， 2024 and June 30， 2025 were retrospectively included. According to the treatment regimen received， the patients were divided into group A [cadonilimab plus oxaliplatin and capecitabine （XELOX）， n ＝54 ] ， group B （sintilimab plus XELOX， n ＝68）， and group C （tislelizumab plus XELOX， n ＝49）. Short-term efficacy after 4 cycles of treatment， survival outcomes， and adverse events were compared among the three groups. Cox regression and Logistic regression analyses were further performed to evaluate the effects of the treatment regimen and baseline data on survival outcomes and the risk of grade 3-4 treatment related adverse events （TRAEs）. RESULTS No statistically significant differences in objective response rate or disease control rate were observed among the three groups （ P ＞0.05）. The median progression-free survival was 7.56 （5.62， 8.11） months in group A， 7.23 （5.33， 8.23） months in group B， and 7.33 （5.42， 8.19） months in group C， with no statistically significant difference among the three groups （ P ＞0.05）. The median overall survival （mOS） was 11.67 （8.82， 13.88） months in group A， 9.78 （6.82， 12.73） months in group B， and 9.69 （6.78， 12.66） months in group C. The mOS was significantly longer in group A than in group B and group C （ P ＜0.05）， whereas no statistically significant difference was observed between group B and group C （ P ＞0.05）. The correlation analysis indicated that treatment regimen， Eastern Cooperative Oncology Group performance status （ECOG PS）， number of metastatic organs， and peritoneal metastasis may be associated with overall survival （OS）. No significant association was observed between treatment regimen and the risk of grade 3-4 TRAEs. The incidences of grade 1-2 or grade 3-4 TRAEs did not differ significantly among the three groups （ P ＞0.05）. CONCLUSIONS In patients with advanced gastric adenocarcinoma or AEG with intermediate， low， or no HER2 expression， cadonilimab plus XELOX may provide a more significant OS benefit with a safety profile comparable to that of sintilimab or tislelizumab plus XELOX. Further studies with larger sample sizes are required to validate these findings.

Objective To analyze the technical essentials of single-microport assisted micro-uni-port thoracoscopic surgery, and to investigate its surgical efficacy and promotional value. Methods Clinical data of patients who consecutively underwent radical upper lobectomy in the Department of Thoracic Surgery of Xi'an International Medical Center Hospital from March 2023 to June 2024 were retrospectively analyzed. According to the surgical approach, patients were divided into two groups: the single-microport assisted group (underwent upper lobectomy via single-microport assisted micro-uni-port thoracoscopy) and the traditional uniportal group (underwent traditional uniportal thoracoscopic lobectomy). Clinical outcomes were compared between the two groups. Results A total of 62 patients were enrolled. There were 30 patients in the single-microport assisted group, with a mean age of (57.4±10.8) years, and 32 patients in the traditional uniportal thoracoscopic group, with a mean age of (57.6±8.7) years. The baseline data were comparable between the two groups. All patients in both groups successfully underwent minimally invasive surgery without conversion to thoracotomy. The operative time in the single-microport assisted group was significantly shorter than that in the traditional uniportal group [(146.03±30.79) min vs. (171.41±36.41) min, P=0.004]. However, there were no statistically significant differences between the two groups in intraoperative blood loss, number of dissected lymph nodes, duration of chest tube drainage, postoperative pain score, postoperative hospital stay, hospitalization cost, or incidence of postoperative complications (all P>0.05). Conclusion Single-microport assisted micro-uni-port thoracoscopic surgery for upper lobectomy can maximally integrate the advantages of three-port and uni-port VATS while effectively avoiding their disadvantages. It significantly shortens the operative time without increasing postoperative pain or complications, and represents a more minimally invasive, safer, and more convenient surgical approach.

Objective: To investigate the dynamic influence mechanism of the interaction between physical exercise and pre-sleep screen time on sleep quality among college students, so as to provide a theoretical basis for sleep health interventions in the population. Methods: From March to April 2025, a convenience sample of 2 075 students was recruited from eight universities in Jiangsu Province to participate in an online survey. Physical exercise was assessed using the Physical Activity Rating Scale-3 (PARS-3), sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI), and pre-sleep screen time behaviors were recorded using a self-designed structured questionnaire. Binary Logistic regression was used to examine the independent associations of physical activity level and pre-sleep screen time with sleep disorders. An interaction effect model was then applied to plot the dose-response relationship among the three variables. Results: The overall prevalence of sleep disorder among college students was 50.3%. Significant differences in the prevalence of sleep disorder were observed across groups of sex, academic discipline, grade, pre-sleep screen time, and physical exercise ( χ 2=42.45, 14.81, 18.99, 113.23, 40.61, all P <0.05). Binary Logistic regression showed that pre-sleep screen time was associated with the risk of sleep disorders (≤15 min: OR =1.70; 16- 30 min : OR =1.91; 31-60 min: OR =3.31; >60 min: OR =5.32), while both moderate ( OR =0.44) and high ( OR =0.57) physical exercise were associated with a reduced risk (all P <0.05). The interaction effect was statistically significant (Wald χ 2= 6.82 , P <0.01). The dose-response curves revealed that, in the low-exercise group, sleep quality deteriorated sharply with increasing screen time (the predicted mean dropped to 28% at the >60 min threshold, P <0.01); in the moderate exercise group, an inverted U-shaped trend was observed, with an optimal window of 16-30 min; and in the high exercise group, a significant buffering effect was found, with the predicted mean remaining at 43% even under >60 min screen exposure, representing a decrease of only 4% compared with the no-screen use group ( P >0.05). Conclusions High screen exposure combined with low physical exercise represents the primary behavioral pattern associated with a high prevalence of sleep disorders. Regular physical exercise can partially offset the negative effects of excessive screen time on sleep.

Objective: To analyze the correlation between ABO blood group compatibility and the risk of early complications after liver transplantation, and to identify risk factors for clinical intervention. Methods: Clinical data of 404 liver transplant recipients and donors were collected. Based on donor-recipient ABO matching, patients were divided into three groups: ABO-Identical (ABO-Id, n=313), ABO-compatible (ABO-c, n=68), ABO-incompatible (ABO-i, n=23). Clinical data, early complications, and associated risk factors were compared. Results: Compared with the ABO-Id, ABO-c and ABO-i recipients were younger, had a higher proportion of primary biliary atresia, and more frequently received living-donor transplantation from relatives (P<0.05). Overall complication rates were: ABO-c 47.1% (32/68), ABO-i 43.5% (10/23), ABO-Id 39.3% (123/313), with no significant intergroup difference (P>0.05). Infection was the most common complication [ABO-c 30.9% (21/68), ABO-i 21.7% (5/23), ABO-Id 17.9% (56/313)]. No significant differences were found in infection, vascular/biliary or acute kidney injury/renal failure among the three groups (P>0.05). However, ABO-c group had significantly higher rates of ascites/abscess (20.6% vs 8.9%, P<0.05) and pleural effusion (14.7% vs 7.0%, P<0.05) than ABO-Id group. There was no significant difference in the incidence of complications and ABO blood group between ABO non-Identical (ABO-c and ABO-i) and Identical groups. Logistic regression analysis showed that the risk of ascites/abscess in ABO non-Identical was higher than that in ABO-Id liver transplantation (P<0.05), and the risk of ascites/abscess after ABO-c liver transplantation was 2.246 times higher than that of ABO-Id liver transplantation. The primary biliary atresia were a risk factor for postoperative ascites/abscess. Conclusion: Enhanced postoperative management is critical for ABO-nonidentical (especially ABO-compatible) recipients, and those with biliary atresia to reduce complication risks.

Objective: To systematically evaluate the association between maternal adverse childhood experiences (ACEs) and offspring social behavior, so as to provide a theoretical basis for further research on intergenerational social behavioral development. Methods: Relevant research literature about maternal ACEs and the development of children s maladaptive social behaviors were collected, from China National Knowledge Infrastructure (CNKI), VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, Embase and SpringLink databases, covering the period from the inception of each database to May 2025. The Chinese database matched and searched through three groups of keywords: "Pregnant women" "Mothers" and "Women"; "Bad childhood experience" "Bad early experience" and "Bad adolescent experience"; "Children" "Teenagers" "Children s behavior" "Children s development" "Teenagers behavior" "Internalized behavior" and "Externalized behavior". The English database was searched by three groups of keywords: "Female" "Pregnant women" "Mothers"; "Adverse childhood experiences" "Adverse early childhood experiences" "Adverse experiences of adolescent"; "Child behavior" "Child development" "Adolescent behavior" "Internalized behaviors" "Externalized behaviors". The selected literature was evaluated for quality and data extraction, with OR and 95% CI as effect indicators. Stata 16.0 software was used for heterogeneity testing, subgroup analysis, and publication bias analysis. Results: A total of 14 studies involving 64 302 mother-child pairs were included. The Meta analysis results showed a significant correlation between maternal ACEs and both offspring maladaptive internalized behaviors ( OR=1.75, 95%CI=1.42-2.15, P <0.01) and externalized behaviors ( OR=1.82, 95%CI=1.51-2.20, P <0.01). The results of subgroup analyses showed that in different regions[internalized behaviors:domestic, foreign OR (95% CI )=2.03(1.49-2.76), 1.55(1.19-2.03); externalized behaviors: domestic, foreign OR (95% CI )=2.41(1.52-3.82), 1.65(1.36-2.01)], study type[internalized behaviors: cohort study, cross sectional study OR (95% CI )=1.64(1.34-2.00), 1.85(1.30-2.65); externalized behaviors: cohort study, cross sectional study OR (95% CI )=1.76(1.46-2.12), 2.12(1.40-3.20)], sample size [internalized behaviors: ≥4 000, <4 000 pairs OR (95% CI )=1.69(1.13-2.55), 1.77( 1.41 -2.24); externalized behaviors: ≥3 000, <3 000 pairs OR (95% CI )=1.72(1.37-2.17), 2.13(1.44-3.15)], there were significant and positive association between mothers ACEs and children s internalizing and externalizing behaviors (all P <0.05). Conclusion A substantial positive association exists between maternal ACEs and the development of offspring maladaptive internalized and externalized behaviors, but the result needs to be continued to be validated by more research.

Objective:To discuss the promotive effect of nerve growth factor(NGF),which is highly expressed in the adipose-derived stem cell(ADSC)-induced Schwann-like cells(SCLCs),on the growth of dorsal root ganglion(DRG)cell processes in the rats,and to clarify its mechanism.Methods:The ADSCs were extracted from the epididymal adipose tissue of the SD rats,and their multidirectional differentiation potential was identified through osteogenic,adipogenic,and chondrogenic induction.The ADSCs were induced to differentiate into the SCLCs,and the expression levels of glial fibrillary acidic protein(GFAP)and S100 calcium-binding protein β(S100β)protein in the ADSCs and SCLCs were detected by immunofluorescence staining and Western blotting methods.The DRG cells were isolated and cultured,and immunofluorescence staining was used to detect the βⅢ-tubulin expression in the DRG cells for identification.The SCLCs were co-cultured with the DRG cells(co-culture group),the single-culture DRG cells were regared as DRG group and toluidine blue staining was used to observe and measure the length of DRG cell processes under the optical microscope in co-culture group and DRG group.Small interfering RNA(siRNA)transfection was used to knock down NGF,and plasmid transfection was used to over-express NGF.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the NGF mRNA expression levels in the cells in various groups;enzyme-linked immunosorbent assay(ELISA)method was used to detect the NGF protein levels in the cell supernatants.The transfected SCLCs were co-cultured with DRG cells and divided into control group,siNC/vector group,NGF knockdown group(si-NGF group),and NGF over-expression group(oe-NGF group).The lengths of DRG cell processes in various groups were observed.Results:The primary ADSCs adhered within 24 h after seeding,with a small number of lipid droplets remaining.After 3 d of culture,the cells were mostly short spindle-shaped,fusiform,or polygonal,growing rapidly in a vortex pattern.After passaging,the cells exhibited a uniform morphology,appearing as long spindles arranged in a fish-school pattern.After 14 d of adipogenic induction,the cell morphology changed from spindle-shaped to flat-round,with translucent lipid droplets forming in the cytoplasm,which were stained red by Oil Red O.After 28 d of osteogenic induction,the cells appeared sand-like with blurred morphology,and calcified nodules were observed,which were stained red by Alizarin Red and deposited in the extracellular matrix.After 28 d of chondrogenic induction in a 3D culture system,millet-sized chondrogenic spheres formed.Frozen sections of the spheres were stained with Alcian Blue,and acidic mucopolysaccharides in the cartilage tissue were stained blue under the microscope.Under the fluorescence microscope,the third-passage purified ADSCs showed positive expression of CD29[fluorescein isothiocy anate(FITC)-labeled green fluorescence]and CD44(Cy3-labeled red fluorescence).The immunofluorescence staining results showed that GFAP was labeled with FITC(green fluorescence),and S100β was labeled with Cy3(red fluorescence).The Western blotting results showed that compared with ADSCs,the expression levels of S100β and GFAP proteins in the SCLCs were increased(P<0.05).The primary DRG cells began to adhere 6 h after conventional culture,and after 3 d,the cell bodies appeared round and bright,with two linear processes extending from them.Under fluorescence microscope,the cells positively expressed the neuron-specific marker βⅢ-tubulin,confirming that the isolated cells were DRG cells.Compared with the ADSCs,the NGF protein expression level in the SCLCs was increased(P<0.05).Compared with DRG group,the length of DRG cell processes in co-culture group was the highest when DRG cells and SCLCs were co-cultured at a 1∶2 ratio(P<0.05).The RT-qPCR results showed that compared with si-NC group,the expression levels of NGF mRNA in the cell supernatant in si-NGF-1,si-NGF-2,and si-NGF-3 groups were significantly decreased(P<0.05),with si-NGF-1 showing the highest knockdown efficiency,which was selected for subsequent experiments.The ELISA results showed that compared with si-NC group,the NGF levels in the cell supernatant of si-NGF-1,si-NGF-2,and si-NGF-3 groups were decreased(P<0.05).Compared with Vector group,the expression level of NGF mRNA and NGF protein level in the supernatant in oe-NGF group were increased(P<0.05).Compared with control group and siNC/vector group,the length of DRG cell processes in si-NGF group was decreased(P<0.05),while the length of DRG cell processes in oe-NGF group was increased(P<0.05).Conclusion:ADSCs can be directionally differentiated into SCLCs,and the differentiated cells highly express NGF.Knockdown or overexpression of NGF can affect the growth of DRG cell processes.
