A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

Severe pneumonia is one of the most common and critical respiratory diseases in clinical practice. It is characterized by rapid progression， difficult treatment， high mortality， and many complications， posing a significant threat to the life and health of patients. The pathogenesis of severe pneumonia is highly complex， and studies have shown that its occurrence and development are closely related to multiple signaling pathways. Currently， the treatment of severe pneumonia mainly focuses on anti-infection， mechanical ventilation， and glucocorticoids， but clinical outcomes are often not ideal. Therefore， finding safe and effective alternative therapies is particularly important. In recent years， with the deepening of research into traditional Chinese medicine （TCM）， it has gained widespread attention in the treatment of severe pneumonia. This paper reviewed the relationship between severe pneumonia and relevant signaling pathways in recent years and how TCM regulated these pathways in the treatment of severe pneumonia. It was found that TCM could regulate the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， NOD-like receptor protein 3 （NLRP3）， and nuclear factor E₂-related factor 2 （Nrf2） signaling pathways， playing a role in reducing the inflammatory response， inhibiting cell apoptosis and pyroptosis， improving oxidative stress， and other effects in the treatment of severe pneumonia. Among these pathways， it was found that all of them regulated inflammation to treat severe pneumonia. Therefore， reducing inflammation is the core mechanism by which Chinese medicine treats severe pneumonia. This review provides direction for the clinical treatment of severe pneumonia and offers a scientific basis for the research and development of new drugs.

Lung cancer is one of the most common and deadliest cancers globally, with its incidence and mortality rates rising each year. Therefore, finding new, safe, and effective alternative therapies poses a significant research challenge in this field. Programmed cell death refers to the process by which cells actively self-destruct in response to specific stimuli, regulated by genetic mechanisms. Modern research indicates that dysregulation of programmed cell death is widespread in the occurrence and progression of lung cancer, allowing cancer cells to evade death while continuing to proliferate and metastasize. Thus, inducing the death of lung cancer cells can be considered a novel therapeutic strategy for treating the disease. In recent years, research on traditional Chinese medicine(TCM) in the field of oncology has gained widespread attention, becoming a focal point. An increasing number of studies have demonstrated that TCM can inhibit the progression of lung cancer and exert anti-cancer effects by inducing apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis. This paper provided a comprehensive review of the molecular mechanisms of programmed cell death in lung cancer, along with the potential mechanisms and research advancements related to the regulation of these processes by TCM, so as to establish a theoretical foundation and direction for future basic and clinical research on lung cancer.

Objective:To evaluate the application of mind mapping in combination with scenario simulation teaching based on symptom management theory (SMT) in geriatric symptom nursing education, and to provide a basis for improving the quality of geriatric symptom nursing education.Methods:A total of 80 nursing students who interned in the Department of Geriatric Medicine of Peking Union Medical College Hospital from August 2022 to April 2023 were included in the study. They were divided into control group and experimental group according to the order of enrollment, with 40 students in each group. The control group employed traditional teaching methods, while the experimental group implemented a method of mind mapping in combination with scenario simulation teaching based on SMT. The general data, training assessment results, and teaching quality satisfaction were compared and analyzed between the two groups. SPSS 22.0 statistical software was used for t-test and chi-square test. Results:There were no significant differences between the two groups in general data such as age, gender, educational background, academic performance, and school of study. The experimental group showed higher scores in geriatric symptom nursing theory assessment [(86.57±8.41) vs. (80.83±9.16), P=0.018] and comprehensive skill assessment [(91.26±7.29) vs. (81.92±8.64), P<0.001], as compared with the control group. The experimental group also showed higher scores in teaching process [(24.52±1.56) vs. (20.18±0.98), P<0.001], teaching methods [(24.49±1.72) vs. (20.65±1.02), P<0.001], teaching effectiveness [(24.35±1.19) vs. (20.01±0.86), P<0.001], teaching content [(24.31±1.83) vs. (20.27±1.21), P<0.001], and overall satisfaction [(97.67±2.80) vs. (81.11±2.53), P<0.001]. Conclusions:The method of mind mapping in combination with scenario simulation teaching based on SMT has a significant positive effect on geriatric symptom nursing education. This method can improve the theoretical and comprehensive skill levels as well as the teaching quality satisfaction of nursing interns.

Objective To compare the prevention and control effects of binocular myopia after wearing orthokeratology lenses or glasses for correction in adolescents with low-to-moderate unilateral myopia.Methods The clinical data of 46 adolescents with unilateral myopia treated in First Affiliated Hospital of Army Medical University were retrospectively analyzed,the patients were divided into the orthokeratology lenses group and spectacles group according to the correction methods,with 23 cases in each group.The axial length(AL),changes in spherical diopter(SD)and anisometropia between the myopic eye and the control eye with orthokeratology lenses spectacles for unilateral myopia correction,and orthokeratology lenses for unilateral and binocular myopia were compared.Results There was no significant difference in baseline AL,SD or anisometropia between the two groups(P>0.05).One year after unilateral myopia correction,the increase of SD for the myopic eye in the orthokeratology lenses group was less than that in the spectacles group(P<0.05),and there was no significant difference in the AL elongation of myopic eyes between the two groups(P>0.05);the elongation of AL for the control eyes in the orthokeratology lenses group was more than that in the spectacles group;the increase of SD for the myopic eyes in the orthokeratology lens group was lower than that in the spectacles group(P<0.05),and there was no significant difference in the increase of SD for the control eyes between the two groups(P>0.05);the anisometropia of patients in the orthokeratology lenses group was less than that in the spectacles group(P<0.05).The biological parameters of the eyes before and after wearing orthokeratology lenses in the patients with monocular and binocular myopia in the orthokeratology lens group were compared,the elongation of AL for the myopic eyes with lens in one eye was less than that with lenses in both eyes(P<0.05),and the elongation of AL for the control eye was more than that with lenses in both eyes(P<0.05),the increases of SD in both myopic eyes and control eyes were more than those with lenses in both eyes(P<0.05),and the anisotropia was more than that with lenses in both eyes(P<0.05).Conclusion Orthokeratology lenses is better than spectacles in controlling the increase of myopia in low-to-moderate unilateral myopia,which can reduce anisometropia between eyes.However,the AL of the emmetropic eye increases rapidly during unilateral myopia correction by orthokeratology lenses,and the progression of binocular myopia can be significantly delayed after wearing orthokeratology lenses.

Objective To investigate the association of 13 single nucleotide polymorphism(SNP)sites in 6 phalange-bone development related genes[fibroblast growth factor receptor 2(FGFR2),indian hedgehog signaling molecule(IHH),Msh homeobox 1(MSX1),Runx family transcription factor 2(RUNX2),SRY-box transcription factor 9(SOX9),Wnt family member 5A(WNT5A)]with human index-ring finger length ratio(2D∶4D).Methods Digital cameras were used to take frontal photographs of the hands of 731 college students(358 males and 373 females)in Ningxia,and image analysis software was used to mark anatomical points and measure finger lengths of index(2th)and ring(4th);genotyping of 13 SNP sites(rs1047057,rs755793,rs41258305,rs3731881,rs3100776,rs12532,rs3821949,rs45585135,rs3749863,rs1042667,rs12601701,rs1829556,rs3732750)for 6 genes by multiplex PCR;One-Way ANOVA or independent sample t-test indirectly assessed the association between 2D∶4D and 13 SNP sites.Results Both left and right hand 2D∶4D were significantly higher in females than males in Ningxia college students(all P<0.01);no statistically significant differences in genotype and allele frequencies of the 13 SNP sites among different sexes(all P>0.05);among different sexes,male left hand 2D∶4D was significantly associated with the genotype of SOX9 gene rs12601701 site(P<0.05)and right hand 2D∶4D was significantly associated with the genotype of WNT5A gene rs1829556 site(P<0.05);the female right hand 2D∶4D was significantly associated with the MSX1 gene rs12532(P<0.01)and rs3821949(P<0.05)sites genotypes.Conclusion SOX9(rs12601701),WNT5A(rs1829556)and MSX1(rs12532 and rs3821949)gene polymorphisms may be associated with the formation of 2D∶4D in Ningxia population.

Hormonal receptor positive human epidermal receptor 2 negative (HR⁺/HER2^-) is the commonest molecular subtype of breast cancer (BC). Patients with HR⁺/HER2^- BC may manifest clinically a late recurrence whose BC metastasizes 10-15 years post-operatively. We report one case who presented with pulmonary mass in upper lobe of lung and Horner syndrome 16 years after BC surgery. FDG PET/CT suggested pulmonary malignancy but could not differentiate between primary or metastatic cancer when invasive biopsy was quite risky. Novel ¹⁸F-FES PET/CT facilitated the non-invasive functional diagnosis of estrogen-receptor positive (ER+) pulmonary metastasis of BC, and the patient experienced partial response (PR) after CDK4/6 inhibitor and aromatase inhibitor as endocrine therapy. This article reviews the diagnosis and treatment process of this case, to provide guidance for non-invasive global evaluation of ER status among metastatic HR⁺/HER2^- BC patients with ¹⁸F-FES PET/CT.

Objective To investigate the efficacy of methylprednisolone in preventing postoperative pulmonary infections in locally advanced esophageal cancer patients undergoing neoadjuvant chemotherapy combined with immunotherapy.Methods A total of 89 patients with locally advanced esophageal cancer treated at the First Affiliated Hospital of Xinxiang Medical University from January 2022 to December 2023 were selected as the research subjects.All patients underwent thoracolaparoscopic radical esophagectomy for esophageal cancer.The patients were randomly divided into an observation group(n=45)and a control group(n=44)using a random number table method.In the observation group,one patient with intraoperative thoracotomy,two patients with extensive pleural adhesion,and one patient with preoperative upper respiratory tract infection were excluded.In the control group,one patient with extensive pleural adhesion and one patient with preoperative upper respiratory tract infection were excluded.As a result,a total of 83 patients were included in the study,with 41 in the observation group and 42 in the control group.Preoperatively,a neoadjuvant treatment regimen of paclitaxel(albumin-bound)+nedaplatin in combination with camrelizumab was given to patients in both groups for 2 cycles.Patients in the control group received conven-tional anti-infection treatment after surgery,while patients in the observation group were intravenously injected with methylpred-nisolone at a dose of 1 mg·kg-1 daily from the first to the third day after surgery.Postoperative inflammatory markers,incidence of postoperative pulmonary infections,incidence of anastomotic fistula,postoperative hospital stay,and total hospitalization costs were compared between the two groups.Results There were no statistically significant differences in leukocyte count,neutrophil ratio,procalcitonin(PCT),high-sensitivity C-reactive protein(hs-CRP),and interleukin-6(IL-6)levels of patients between the two groups before treatment(P＞0.05).On day 1 and 4 after treatment,patients in the observation group had significantly higher leu-kocyte count,neutrophil ratio,PCT,hs-CRP,and IL-6 levels compared to those before treatment(P＜0.05).On postoperative day 4,the leukocyte count,neutrophil ratio,PCT,hs-CRP,and IL-6 levels were significantly lower than those on day 1 postopera-tively(P＜0.05).On postoperative days 1 and 4,the leukocyte count,neutrophil ratio,PCT,hs-CRP and IL-6 levels of patients in the control group were significantly higher than those in the preoperative period(P＜0.05),and the leukocyte count,neutro-phil ratio and hs-CRP level were significantly lower on day 4 after surgery than on day 1 after surgery(P＜0.05);the differe-nces in PCT and IL-6 level of patients between day 4 after surgery and day 1 after surgery were not statistically significant(P＞0.05).On postoperative day 1,there were no statistically significant differences in leukocyte count,neutrophil ratio,PCT,hs-CRP,and IL-6 levels between patients in the observation group and the control group(P＞0.05).On postoperative day 4,the leukocyte count,neutrophil ratio,PCT,hs-CRP,and IL-6 levels of patients in the observation group were significantly lower than those in the control group(P＜0.05).The incidence of pulmonary infections in patients in the control group and the ob-servation group was 30.9％(13/42)and 12.2％(5/41),respectively;the incidence of pulmonary infections in patients in the observation group was significantly lower than that in the control group(x2=4.298,P＜0.05).The incidence of anasto-motic fistula in patients in the observation group and the control group was 9.76％(4/42)and 21.43％(9/42),respectively;there was no statistically significant difference between the two groups(x2=2.140,P＞0.05).The postoperative hospital stay was significantly longer in the control group than in the observation group(P＜0.05),and the total hospitalization costs were significantly higher in the control group than in the observation group(P＜0.05).Conclusion Methylprednisolone can effec-tively reduce the levels of inflammatory markers and the incidence of postoperative pulmonary infections in esophageal cancer patients undergoing neoadjuvant chemotherapy combined with immunotherapy before surgery.It is a highly safe treatment thera-py without increasing the incidence of anastomotic fistula.
