Objective:To observe the clinical efficacy of gentle moxibustion at different temperatures in treating people with diarrhea-predominant bowel syndrome(IBS-D)due to spleen deficiency.Methods:A total of 108 IBS-D patients were divided into two groups using the random number table method,with 54 participants in each group.Moxibustion group 1 received gentle moxibustion at(43±1)℃at bilateral Tianshu(ST25)and Zusanli(ST36),lasting 30 min each session;moxibustion group 2 received gentle moxibustion at(37±1)℃at the same points.Both groups received the intervention 3 times weekly for a total of 18 sessions.Abdominal pain intensity,stool form,pattern-based efficacy,quality of life,and mental health assessments were performed at weeks 0,3,6,and 8.Results:The total effective rate for abdominal pain intensity was 87.8%in moxibustion group 1 versus 51.1%in moxibustion group 2,and the difference was statistically significant(P<0.05).When the treatment finished,abdominal pain intensity,the Bristol score,IBS-symptom severity scale(IBS-SSS)score,self-rating anxiety scale(SAS)score,and self-rating depression scale(SDS)score dropped significantly in both groups(P<0.05),and the IBS-quality of life(IBS-QOL)score increased markedly(P<0.05).Between-group comparisons demonstrated that abdominal pain intensity,the Bristol general score,IBS-SSS score,traditional Chinese medicine(TCM)pattern score,and SDS score were significantly lower in moxibustion group 1 than in moxibustion group 2 at treatment week 6(P<0.05),and the IBS-QOL score was notably higher in moxibustion group 1(P<0.05).Conclusion:Whether at 43℃or 37℃,gentle moxibustion at Tianshu(ST25)and Zusanli(ST36)can improve abdominal pain,stool form,and quality of life,reduce disease severity,and mitigate TCM pattern in IBS-D patients;43℃gentle moxibustion performs better than 37℃gentle moxibustion in improving abdominal pain,stool form,disease severity,TCM pattern,quality of life,anxiety,and depression in IBS-D.

[Purpose]To analyze the incidence and mortality of gastric cancer in Hefei City of Anhui Province in 2020 and the trend from 2013 to 2020.[Methods]The incidence and mortality data of gastric cancer in Hefei City from 2013 to 2020 were collected from sofeware CanReg4.The incidence(mortality)rate,age-standardized incidence(mortality)rate by Chinese standard popula-tion and world standard population(ASIRC/ASIRW,ASMRC/ASMRW),age-specific incidence(mortality)rate and average annual percentage change(AAPC)of the incidence(mortality)rate were calculated.[Results]In 2020,the crude incidence rate of gastric cancer in Hefei was 47.14/105,the ASIRC was 27.10/105,the ASIRW was 26.78/105,ranking the second in all cancer types.The crude mortality rate of gastric cancer was 41.12/105,the ASMRC was 21.64/105,the ASMRW was 21.25/105,ranking the second in all cancer types.The incidence rate and mortality rate of gastric cancer increased with age,and reached the peak in the age group of 80～84 years old.The incidence rate and mortality rate of men were higher than those of women,and rates in rural areas were higher than those in urban areas.The ASIRC and ASMRC of gastric cancer showed downward trends from 2013 to 2020 in Hefei(AAPC were-7.19％and-4.71％,both P＜0.05).[Conclusion]The ASIRC and ASMRC of gastric cancer show downward trends from 2013 to 2020 in Hefei,but are still higher than the average level in China,so the prevention and control work should be fur-ther strengthened.

With the continuous development of refractive surgery, people's focus has gradually shifted from improving vision to improving visual quality, and personalized laser-assisted in situ keratomileusis(LASIK)surgery has gradually become people's preferred choice. Femtosecond laser-assisted keratoplasty provides better advantages for personalized LASIK surgery. This article mainly introduces the commonly used femtosecond laser-assisted personalized LASIK surgery(FS-LASIK)in recent years, such as wavefront-optimized, wavefront-guided, topography-guided, Q value-guided(aspheric cutting), personalized surgery “Wavelight Plus” and personalized surgery when correcting patients with age-related inadequate accommodation. This article focuses on analyzing the advantages and disadvantages of different personalized FS-LASIK, as well as the research progress in recent years, and also focuses on comparing the differences between different personalized surgeries.

Objective:To analyze the influencing factors of image quality of high-frequency ultrasound at the level of the glottis in healthy adults.Methods:A cross-sectional study was conducted on 433 healthy voluteers who underwent routine neck ultrasound examination at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2023 to April 2024 and met the inclusion criteria. General data of the subjects were collected，and the image quality was graded. Gender，age，height，weight，body mass index，body surface area，thyroid cartilage calcification ratio，thickness of anterior cervical subcutaneous soft tissue and thickness of anterior cervical muscle group were analyzed by using multivariable Logistic regression for the influencing factors of image quality.Results:The display rates of the vocal cord epithelial layer and lamina propria，vocal cord muscle layer and paraglottic space structures in the para-thyroid cartilage section were superior to those in the anterior median section，with statistically significant differences（all P<0.05）. There were statistically significant differences in image quality grading among different age groups（all P<0.05），and image quality deteriorated as age increased. Logistic multivariate analysis indicated that gender，age and thyroid cartilage calcification ratio were independent factors affecting image quality（all P<0.05）. With age increased，thyroid cartilage calcification at the glottic level could be concentrated in the anterior，middle and posterior parts，respectively，and subsequently，calcification in the anterior and middle or middle and posterior parts gradually fused until complete calcification occurred. Conclusions:High-frequency ultrasound can clearly display the structures of most normal adult larynges at the glottis level，with the lateral section of the thyroid cartilage being superior to the median anterior neck section. As age increases，the degree of thyroid cartilage calcification increases，and image quality worsens.

Objective:To construct a VP8-mRNA vaccine using human rotavirus spike protein VP8 domain as the immunogen and analyze its immunogenicity in mice.Methods:The VP8-mRNA sequence was designed, optimized, and synthesized. The VP8 gene of rotavirus G1P[8] type was used to construct the plasmid pUC57-VP8-Kan-SapⅠ, which was then sequenced. The plasmid confirmed by sequencing was subjected to large-scale amplification and extraction, followed by linearization, in vitro transcription, and capping. The purified capped products were encapsulated with lipid nanoparticles using a microfluidic control apparatus. The encapsulated VP8-mRNA vaccine was administered intramuscularly to mice at 10, 15, and 20 μg. Serum samples were collected for antibody detection by ELISA. Cellular immune responses were detected by flow cytometry and ELISPOT. Statistical analysis was performed using one-way or two-way analysis of variance and Tukey-Kramer test. Results:The encapsulated VP8-mRNA vaccine was rounded and spherical, with a particle size of about 100 nm, a polymer dispersion index of 0.088, and an encapsulation rate of 92.3%. Two doses of VP8-mRNA vaccine immunization could induce a good immune response in mice. The level of IgG antibody induced after immunization in the 15 μg group was comparable to that of the 20 μg group, and there was no statistical difference ( P>0.05), but the antibody levels in the two groups were significantly higher than that in the 10 μg group ( P<0.000 1). VP8-mRNA vaccine could induce neutralizing antibodies against rotavirus G1 and G9 types. The highest level of neutralizing antibodies against rotavirus type G1 was observed in the 15 μg group, which was significantly higher than that in the 10 μg group ( P<0.05). All immunization groups exhibited good neutralizing ability against rotavirus G9 type. The results of ELISPOT showed that lymphocytes from mice in each vaccine group were able to secrete IFN-γ when stimulated with VP8 peptide. Flow cytometry showed that the proportions of CD8 + T cell subsets in the vaccine groups were higher than that in the control group. Conclusion:The VP8-mRNA vaccine has good immunogenicity in mice and can induce good humoral and T-cell immune responses.

Objective:To investigate the clinical efficacy of lumbar lateral interbody fusion (LLIF) versus posterior lumbar interbody fusion (PLIF) in the treatment of severe lumbar spinal stenosis.Methods:The data of patients with severe lumbar spinal stenosis who underwent LLIF or PLIF from February 2019 to December 2023 were retrospectively analyzed. There were 30 patients in the LLIF group, 10 males and 20 females, aged 62.7±5.6 years (range, 53-74 years), including 21 cases of single segment and 9 cases of double segment. There were 46 patients in the PLIF group, including 20 males and 26 females, aged 63.2±8.4 years (range, 43-75 years), 40 cases of single segment and 6 cases of double segment. The visual analogue scale (VAS), Oswestry disability index (ODI), intervertebral space height, intervertebral foramen height and postoperative complications were compared between the two groups.Results:All patients were followed up for an average of 21.3±6.4 months (range, 12-32 months). The intraoperative blood loss in the LLIF group was 112.2±76.9 ml, which was significantly lower than 193.9±88.2 ml in the PLIF group ( P<0.05). The VAS scores of back pain and leg pain after operation were significantly lower than those before operation in the two groups ( P<0.05). There was no statistically significant difference between groups in back pain VAS scores at preoperative, 6 months postoperative, and final follow-up ( P>0.05); the back pain VAS score at 1 month postoperatively in the LLIF group was 1.6±1.2, which was less than 2.8±0.7 in the PLIF group ( P<0.05). There was no statistically significant difference between groups in leg pain VAS scores at preoperative, 1 month postoperative, and 6 months postoperative ( P>0.05); the leg pain VAS score at the final follow-up in the LLIF group was 1.2±1.5, which was smaller than 1.8±1.0 in the PLIF group ( P<0.05). The postoperative ODI was smaller than the preoperative one in both groups, and the difference was statistically significant ( P<0.05); the preoperative, 1-month postoperative, 6-month postoperative, and final follow-up ODIs in the LLIF group were 45.7%±16.0%, 17.9%±12.0%, 16.2%±11.6%, and 15.7%±11.7%, and those in the PLIF group were 47.9%±15.4%, 20.1%±9.3%, 16.9%±10.6%, and 14.6%±11.0% in the PLIF group, and the difference between the groups was not statistically significant ( P>0.05). The preoperative intervertebral space height in the LLIF group was 10.6±2.0 mm, which was smaller than that in the PLIF group 11.8±2.2 mm ( P<0.05). The intervertebral space heights in the immediate postoperative period and at the final follow-up were 13.3±2.3 mm and 12.3±2.2 mm in the LLIF group and 13.7±1.7 mm and 13.0±1.9 mm in the PLIF group ( P>0.05). The preoperative intervertebral foraminal height in the LLIF group was 18.0±3.2 mm, which was smaller than that of 19.7±2.4 mm in the PLIF group ( P<0.05); the intervertebral foraminal heights in the immediate postoperative period and at the final follow-up were 21.4±2.5 mm and 20.2±2.4 mm in the LLIF group, and in the PLIF group were 20.7±2.4 mm and 19.7±2.6 mm in the PLIF group ( P>0.05). In the LLIF group, 2 cases had femoral nerve injury and 2 cases had transient back pain after operation. There were 2 cases of cerebrospinal fluid leakage, 1 case of screw loosening, and 2 cases of deep vein thrombosis in the PLIF group. In the PLIF group, 2 patients underwent revision, including 1 case due to cage displacement and 1 case due to screw malposition. The fusion settling rate was 21% (8/39) in the LLIF group and 12% (6/52) in the PLIF group ( P>0.05). Conclusion:Both LLIF and PLIF can effectively restore the intervertebral height, improve the lumbar function and the symptoms of back and leg pain in the treatment of severe lumbar spinal stenosis.

Postoperative pain is a common clinical phenomenon,and patient-controlled analgesia(PCA)is currently the most widely used and optimal analgesic method.Postoperative follow-up can guide pa-tients in the correct use of PCA,thereby effectively alleviating postoperative pain.To date,there has been no expert consensus or guideline to standardize clinical practices in this regard.To address this gap,Peking Union Medical College Hospital,Chinese Academy of Medical Sciences&Peking Union Medical College,China-Japan Friendship Hospital,and the Clinical Anesthesia Quality Management Group of the Chinese Society of Anesthesiology jointly initiated and organized a panel of clinicians and nurses specializing in postoperative pain management and research to develop the Expert Consensus on Postoperative Patient-controlled Analgesia Follow-up in Adults(2025).Based on the latest evidence-based data and expert clinical experience,this consensus provides preliminary recommendations in three key areas:the composition of the Patient-controlled Analgesia follow-up team,suitable patient populations,and follow-up and nursing care.It aims to offer valuable guidance for the standardized management of PCA in postoperative patients.

Objective To investigate the risk factors for ligamentum flavum hypertrophy(LFH)and its correlation with clinical symptoms in patients with degenerative lumbar spinal stenosis(DLSS).Methods The clinical and imaging data of 79 patients with DLSS were collected.Patients were divided into four groups based on LFH severity.Quantitative parameters,including lumbar lordosis(LL),sacral slope(SS),facet tropism,facet joint effusion,intervertebral height index,dural sac cross-sectional area(CSA),epidural fat area,and fat infiltration rate(FIR)of the paraspinal muscle were measured on imaging.One-way analysis of variance was used to compare the differences in these parameters among groups.Multiple linear regression analysis was performed to identify the risk fac-tors for LFH,and the correlation between LFH severity and clinical manifestations was analyzed.Results The results of one-way analy-sis of variance showed that there were statistically significant differences among the four groups of patients in terms of sex,body mass index(BMI),LL,epidural fat area and FIR of the multifidus(MF).Multiple linear regression analysis identified that BMI,LL,and epidural fat area as independent risk factors for LFH.Correlation analysis indicated a weak positive association between LFH and dis-ease duration(r=-0.231,P=0.041).Conclusion In DLSS patients,LFH is weakly correlated with disease duration,while BMI,LL,and epidural fat area are risk factors for LFH.

Objective:To evaluate the clinical efficacy and impact on quality of life of the biofeedback (BF) therapy combined with the Wenyang Yiqi Prescription and self-efficacy interventions in patients with functional defecation disorders (FDD).Methods:A prospective, randomized controlled trial design was employed. A total of 128 FDD patients were selected from the Pelvic Floor Center of the Department of Proctology, Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine, between January 2021 and April 2023. These patients were randomly divided into two groups, with 64 cases in each group. Additionally, 41 historical control patients, who had received conventional BF training between June 2015 and January 2018 at the same center, were included for comparison. The historical control group received conventional BF therapy, the intervention group 1 combined BF therapy with self-efficacy interventions, and the intervention group 2 added the Wenyang Yiqi Prescription based on intervention group 1's treatment. All three groups underwent two treatment courses. Constipation symptom scores before and after treatment were performed; self-efficacy was assessed via the Self-Rated Abilities for Health Practices scale (SRAHP); health behaviors were evaluated using the Health-Promoting Lifestyle Profile (HPLP); anxiety and depression were evaluated through Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS); quality of life was measured through SF-36. Clinical efficacy was evaluated based on constipation symptom scores.Results:During the treatment period, seven patients dropped out due to personal reasons, leaving 61 patients in intervention group 1 and 60 patients in intervention group 2 for efficacy analysis.　The total effective rates were 80.32% (49/61) in intervention group 1, 83.33% (50/60) in intervention group 2, and 56.10% (23/41) in the historical control group. The total effective rates of both intervention groups were significantly higher than those in the historical control group ( χ2=7.06, 9.15; P=0.029, 0.010, respectively). After treatment, intervention group 2 showed significantly lower constipation-related straining scores [1 (1, 2) vs. 2 (1, 2), Z=-4.51] compared to intervention group 1 ( P<0.05). Additionally, intervention group 2 had lower scores for straining [1 (1, 2) vs. 2 (1, 2), Z=-3.15] and defecation time [1 (0, 1) vs. 1 (1, 2), Z=-3.13] compared to the historical control group ( P<0.05). Psychological comfort efficacy (19.13 ± 2.51 vs. 16.98 ± 1.86, t=5.36), health responsibility efficacy (23.63 ± 4.69 vs. 22.59 ± 3.05, t=2.06), and overall SRAHP scores (75.98 ± 4.44 vs. 72.33 ± 5.16, t=4.17) were higher in intervention group 2 compared to intervention group 1 ( P<0.05). The HPLP scores (79.33 ± 11.13 vs. 72.80 ± 9.20, t=3.10) of intervention group 2 were higher than those of the historical control group ( P<0.05). Emotional functioning scores (75.98 ± 18.45 vs. 68.92 ± 20.58 and 68.55 ± 18.21, F=20.91) in intervention group 2 were higher than in both intervention group 1 and the historical control group ( P<0.05). Conclusion:The combination of the Wenyang Yiqi Prescription with BF therapy and self-efficacy interventions effectively improves the clinical symptoms and quality of life in FDD patients.
