Objective To explore the application of the GPT-4 large language model in simplifying lung cancer radiology reports to enhance patient comprehension and doctor–patient communication efficiency. Methods A total of 362 radiology reports of non-small cell lung cancer (NSCLC) patients were collected from two hospitals between September and December 2024. Interpretive radiology reports (IRRs) were generated using GPT-4. Original reports (ORRs) and IRRs were compared through radiologist consistency evaluation and volunteer-based assessments of reading time, comprehension scores, and simulated communication duration. Results The average word count of ORRs was (459.83±55.76) words, compared with (625.42±41.59) words for IRRs (P<0.001). No significant differences were observed in expert consistency scores between ORRs and IRRs across dimensions of image interpretation accuracy, report detail completeness, explanatory depth and insight, and clinical practicality. Compared with reading ORRs, volunteers (simulated patient) read IRRs with shorter time [(346.88±29.15) s versus (409.01 ±102.40) s], with higher comprehension scores [(7.83±1.04) points versus (5.53±0.94) points] and shorter doctor-patient communication times [(317.31±57.81) s versus (714.20±56.67) s]. All differences were statistically significant (all P<0.001). Conclusion GPT-4 generated IRRs significantly improve patient comprehension and shorten communication time while maintaining medical accuracy. These findings suggest a new approach to optimizing radiology report management and enhancing healthcare service quality.

To compare the effect of three different surface zirconium oxide treatments on binding strength and fracture patterns between zirconia and veneering ceramics.
 Methods: A total of 40 zirconia specimens and 10 nickel-chromium alloy were divided into 5 groups (n=10 in each group): a treatment group by zirconium oxide sand-blaste (Group A), a zirconia bonded porcelain group (Group B), a hot-etching solution group (Group C), a non-treatment zirconia (Group D) and a non-treatment nickel-chromium alloy group (Group E). After all treatments, a veneering porcelain (4 mm×4 mm×2 mm) was formed onto the center of all substrate specimens by plastic coating method. Shear bond strength (SBS) test with a universal testing machine was used in each group. Scanning electron microscopy was used to observe the surface morphology of the damaged specimen interface, which was randomly selected from each group.
 Results: The SBS test showed that there was no significant difference in SBS results between the Group A, the Group B and the Group D (both P>0.05), and both of them were significant less than that in the group E (both P<0.05). The SBS results in the Group C were significantly higher than that in the Group D, the Group A, and the Group B (all P<0.05), but there were no significant difference compared with that in the Group E (P<0.05). 
 Conclusion: Sand-blaste and liner application on zirconia ceramic contribute no effect to binding strength between zirconia and veneering ceramics, but hot-etching solution can increase the binding strength between zirconia and veneering ceramics.

BACKGROUND: Recent literatures have showed that percutaneous kyphoplasty can effectively avoid nerve damage, pulmonary embolism, and insufficient vertebral height and other security risks when bone cement is infused into affected vertebrae in percutaneous vertebroplasty. OBJECTIVE: To compare the effect of percutaneous kyphoplasty and percutaneous vertebroplasty in repair of osteoporotic vertebral compression fractures. METHODS: A total of 106 patients with senile osteoporotic vertebral compression fractures were randomly divided into trial group and control group (n=53 per group). Patients in the trial group were treated with percutaneous kyphoplasty, and those in the control group treated with percutaneous vertebroplasty. Al patients were fol owed up for 6 months after repair. The vertebral compression deformation, bone cement distribution, midline vertebral bone cement condition, vertebral height restoration, bone cement leakage, vertebral kyphosis, progressive spinal col apse, nerve damage, as wel as visual analog scale scores and Oswestry disability index scores in these two groups were compared. RESULTS AND CONCLUSION: Compared with the control group, there was less bone cement leakage and vertebral compression deformation in the trial group. Moreouer, in the trial group, bone cement distributed uniformly, vertebral height restoration was good and effective, pain was obviously relieved, and the probability of vertebral kyphosis, progressive spine col apse and nerve damage was significantly reduced (al P < 0.05). These results suggest that percutaneous kyphoplasty can effectively relieve the pain of patients with osteoporotic vertebral compression fractures, restore vertebral body height and reduce the incidence of complications, which effectively guarantees the postoperative restoration of motor function.

The fibrosis can occur in many kinds of organs,and its sustained progress may lead to organ structural damage and functional decline,and even the organ failure,which threatens the human health and the life seriously.Adenosine is an endogenous purine nucleoside that can be generated in various tissues of the body and regulate a multitude of body functions via the combina-tion with four different kinds of G protein-coupled receptors.Re-cent studies have found that adenosine receptors play an impor-tant role in regeneration tissue and fibrosis process.To under-stand the processes may be helpful to the treatment of fibrosis diseases.This review makes a summary on latest research pro-gress of adenosine receptors in fibrosis diseases.

Aim To investigate the influence of down-regulating adenosine A1 receptor and adenosine A2 A receptor gene expression on proliferation and activation of acetaldehyde-induced hepatic stellate cell-T6 cells through siRNA. Methods Alcoholic liver fibrosis in vitro model was constructed by inducing HSC-T6 cells with acetaldehyde. siRNA targeting A1R and A2AR were designed and synthesized according to its mRNA. The siRNA was transfected into rat HSC-T6 cells by li-posome LipofectamineTM 2000. HSC cell proliferation was measured by MTT. The mRNA levels of A1R, A2AR, α-SMA, Collagen I in the supernatant of the cell culture were measured by Quantitative Real-Time PCR. The protein levels of A1R, A2AR, α-SMA, Collagen I were measured by Western blot. Results A1 R and A2 AR siRNA effectively inhibited the cell proliferation, and they also significantly decreased the levels of A1R, A2AR,α-SMA, Collagen I, suggesting that A1 R and A2 AR might be potential target genes in the alcoholic liver fibrosis. Conclusions Silencing A1 R or A2 AR by RNAi can significantly inhibit the HSC proliferation, A1R and A2AR may be potential therapeutic target genes for alcoholic liver fibrosis.

Objective To construct vector expressing soluble mPDL1-hIgGFc and study its effect on the proliferation and apeptosis of cells in vitro. Methods The extrncellular domain of mPDL1 gene was amplified from pmPDL1 vector by PCR and inserted into phIgGFc vector. The recombinant pmPDL1-hIgGFc was transfected into CHO cells by LipofectAMINETM2000, and the transfected cells were named as CHOp. The expression of mPDL1-hIgGFc in the culture supernatants of CHOp was assayed by ELISA and Western blot. The effects of CHOp culture supernatants on mixed lymphocyte culture(MLC) was analysed by Flowm-etry. Results The extracellular domain of mPDL1 gene were obtained from PCR. DNA sequencing and the identification of digestion by HindⅢ and KpnⅠ indicated the recombinant plasmid pmPDL1-hIgGFc was suc-cessfully constructed. ELISA and Western blot analysis proved that the CHOp could express mPDL1-hIgG-Fc. CHOp culture supernatants could inhibit lymphocyte proliferation and induce the apoptosis of the activa-ted T cells in MLC in vitro in a dose-dependent manner. Conclusion The mPDL1-hIgGFc protein could in-hibit lymphocyte proliferation and induce the apoptosis of the activated T cells.
