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.

Objective:To analyze the drug-resistance pattern and molecular epidemiological characteristics of Enterobacteriales carrying the blaNDM gene in Lishui, aiming to guide clinical anti-infection treatment. Methods:Non-duplicate blaNDM-carrying Enterobacteriales, isolated from Lishui Central Hospital, were collected and identified by VITEK MS. The minimal inhibitory concentrations (MICs) were detected by the broth microdilution method. The ST types of the strains were determined by multilocus sequence typing (MLST). Plasmid types were identified by transformation or conjugation experiments and replication initiator amplification experiments. The transposon structures were detected by PCR amplification. Finally, the epidemic regularity of blaNDM gene in Lishui was analyzed from three levels: clonal group, plasmid, and mobile genetic elements. Results:A total of 109 blaNDM-positive strains were collected. Among them, 60 strains carried the blaNDM-1 gene and 49 strains carried the blaNDM-5 gene. The 109 strains showed 100% resistance to ceftazidime and cefotaxime. The resistance rates to peracillin-tazobactam and imipenem were higher than 80%. Strains carrying the blaNDM-5 gene were more resistant to meropenem than those carrying blaNDM-1 gene( P<0.05). A total of 68 STs were detected from 109 strains, and IncX3, IncFⅡγ, IncA/C and IncT/R plasmids were detected, and 90.83% of the blaNDM genes were located in the IncX3 plasmid. Twelve types of blaNDM gene surrounding structures existed, and they all carried the highly conserved blaNDM- bleMBL- trpF gene sequence. Conclusions:The blaNDM gene has diverse transmission modes in Lishui. The IncX3 plasmid is the main factor mediating its transfer, and all strains carry highly conserved blaNDM- bleMBL- trpF gene sequence.

The integrated medical and elderly care is a major livelihood issue in China, and also an important measure to positively respond to the national strategy of population aging.In July 2024, the Aging Health Department of the National Health Commission issued the "Standard for the Elderly to Shift of Beds Between Elderly Care and Medical Zones Within the Integrated Area of Medical Treatment and Maintenance(WS/T845-2024)" . This standard takes comprehensive geriatric assessment as the main focus, determines the dynamic evaluation indicators for bed conversion between elderly care and medical zones, and establishes an evaluation standard, which is of great significance for standardizing the development of the integrated area of medical treatment and maintenance and meeting the health needs of the elderly in different periods.This article introduced the background and significance of the standard formulation, interpreted the content of the standard in detail, and summarized the overall thinking and usage methods when formulating the standard, which was helpful for relevant personnel to correctly understand the standard and promote its implementation.

Objective:Comparative study on the application value of bronchial ultrasound combined with different biopsy methods under thin-layer CT navigation in the diagnosis of malignant peripheral lung lesions.Methods:A retrospective analysis of patients with suspected malignant peripheral lung lesions identified by chest CT from January 2019 to September 2024 at the Cancer Hospital of the Chinese Academy of Medical Sciences and Peking Union Medical College, and Xianyang Central Hospital, who underwent routine bronchoscopy with negative results (209 cases). These patients were diagnosed using bronchial ultrasound under thin-layer CT navigation. The cases were divided into a cryobiopsy group (127 cases) and a conventional forceps biopsy group based on the biopsy method (82 cases). The diagnostic rates of the two groups were statistically analyzed, along with factors influencing the diagnostic rates. The tissue size obtained from both groups was compared, and the occurrence of complications was summarized.Results:This study included 209 cases with 216 peripheral lung lesions. A total of 209 cases with 210 lesions were successfully located through thin-slice CT guidance, resulting in a guiding success rate of 97.2% (210/216). Among the 130 lesions in the cryobiopsy group, 78 lesions were diagnosed as lung malignancies, with a diagnostic rate of 82.1% (64/78) for cryobiopsy in lung malignant lesions. In the forceps biopsy group, 46 of the 86 lesions were diagnosed as lung malignancies, with a diagnostic rate of 87.0% (40/46) for forceps biopsy in lung malignant lesions. There was no statistically significant difference between the two diagnostic rates ( P=0.473). The average longest diameter of tissue obtained by cryobiopsy was (6.11±0.23) mm, while the average longest diameter of tissue obtained by forceps biopsy was (1.58±0.43) mm. There was a statistically significant difference in tissue longest diameter between the two groups ( P＜0.001). When the distance from the bronchoscopic tip to the lesion was ≥3 cm and the most distal bronchus visible under bronchoscopy was ≤5th generation, the diagnostic rate of forceps biopsy was higher [83.3%(25/30) and 94.1%(32/34)] than that of cryobiopsy [79.3%(23/29) and 78.0%(46/59)], and the difference was statistically significant ( P＜0.05). Regarding complications, one case (1.3%, 1/78) of clinically significant complications occurred in the cryobiopsy group, while no complications occurred in the forceps biopsy group. Conclusions:Under thin-layer CT navigation, bronchial ultrasound combined with different biopsy methods demonstrates a high diagnostic rate for malignant peripheral lung lesions and is safe to operate. Cryobiopsy allows for the collection of larger tissue specimens.

Objective:To analyze the efficacy of phantom-less quantitative computer tomography (PL-QCT) for the diagnosis of osteoporosis in patients with lumbar degenerative diseases.Methods:From October 2021 to October 2023, a total of 1 248 patients with lumbar degenerative disease who did not receive anti-osteoporosis treatment in the Department of Spine Surgery, Tianjin Hospital were retrospectively analyzed. There were 520 males and 728 females, aged 62.31±9.37 years (range, 40-87 years), height 1.66±0.08 m (range, 1.43-1.89 m), weight 69.04±8.27 kg (range, 49-93 kg). The mean body mass index was 26.11±3.67 kg/m 2 (range, 14.40-37.11 kg/m 2). Dual-energy X-ray absorptiometry (DXA) and PL-QCT were used to diagnose osteoporosis, and the detection rates of the two diagnostic methods were compared. The receiver operating characteristic (ROC) curve of PL-QCT for the diagnosis of osteoporosis was drawn, the area under the curve (AUC) and 95% confidence interval (CI), sensitivity and specificity were calculated. Results:Among 1 248 patients with lumbar degenerative diseases, 626 (50.2%) were diagnosed as osteoporosis by PL-QCT, 423(33.9%) were diagnosed by spine DXA, 488(39.1%) were diagnosed by hip DXA and 539 patients(43.2%) were diagnosed by dual-site DXA. The detection rate of osteoporosis of PL-QCT was higher than that of spine DXA (χ 2=193.557, P<0.001), hip DXA (χ 2=322.201, P<0.001) and dual-site DXA (χ 2=94.683, P<0.001), and the difference was statistically significant. Taking the diagnostic results of spinal DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 79%, a specificity of 81%, and an AUC and 95% CI of 0.82(0.79, 0.85). Taking the diagnostic results of hip DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 85%, a specificity of 55%, and an AUC and 95% CI of 0.75(0.71, 0.78). Taking the diagnostic results of two-site DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 72%, a specificity of 75%, and an AUC and 95% CI of 0.81(0.78, 0.83). Conclusion:Compared with DXA, PL-QCT has a higher detection rate of osteoporosis in patients with degenerative lumbar spine disease and good diagnostic efficacy.

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.

Kidney transplantation is widely recognized as the optimal treatment for children with end-stage renal disease(ESRD),offering significant improvements in growth,development,and long-term quality of life compared with prolonged dialysis.However,kidney transplantation in low-age(＜5 years old)and low-weight(＜15 kg)children presents significant clinical challenges due to their delicate vas-cular structures,limited surgical space,and complex perioperative management.This report presents two cases of kidney transplantation in low-age,low-weight children performed at Peking University People's Hospital.Case 1:a 2-year-3-month-old boy(8.8 kg),presenting a preoperative serum creatinine of 248μmol/L post-dialysis and the estimated glomerular filtration rates(eGFR)of 35.17 mL/(min·1.73 m2).Case 2:a 3-year-8-month-old girl(11.25 kg),presenting a preoperative creatinine of 281 μmol/L post-dialysis and the eGFR of 22.63 mL/(min·1.73 m2).Both recipients underwent transplantation via the extraperitoneal approach,with end-to-side anastomosis of the donor renal artery and vein to the recipient's common iliac artery and vein,respectively.The ureters were anastomosed to the bladder using the tunnel technique,and double-J stents were placed intraoperatively.The surgeries were uneventful,and both pa-tients exhibited rapid recovery of renal function.Postoperatively,serum creatinine levels decreased to 26μmol/L(Case 1)and 39 μmol/L(Case 2)by the third day,with the eGFR reaching 245.23 mL/(min·1.73 m2)and 164.12 mL/(min·1.73 m2),respectively.No complications,such as vascular thrombosis,ureteral stenosis,or abdominal compartment syndrome were observed during follow-up.A comprehensive literature review was conducted to contextualize these cases within global advancements in pediatric renal transplantation.Current evidence highlights the growing adoption of kidney transplantation for low-age,low-weight children,though debates persist regarding optimal surgical strategies(specifical-ly,the intraperitoneal versus extraperitoneal approaches).This case report underscores the feasibility of the extraperitoneal approach in overcoming anatomical limitations of low-weight pediatric recipients,with distinct advantages including reduced gastrointestinal complications and enhanced accessibility for post-operative ultrasound monitoring.Furthermore,mean arterial pressure(MAP)and central venous pressure(C VP)were systematically monitored intraoperatively to ensure optimal renal blood perfusion and graft viability.Our single-center experience provides valuable insights into surgical strategy selection and peri-operative management for this high-risk population.Nevertheless,larger multicenter studies are warranted to validate long-term outcomes and refine standardized protocols.

Objective:To investigate the effect of basket assisted retrograde ureteral soft lithotripsis retrograde intrarenal surgery (RIRS) in the treatment of subcalyceal calculi and its effect on stone clearance.Methods:A retrospective cohort study method was conducted on 120 patients with lower calyx stones treated at Jiaozhou Central Hospital of Qingdao City, from October 2021 to January 2024. There were 66 males and 54 females, aged (48.10±10.11) years old. The patients were divided into two groups based on their surgical methods: 60 patients who received only RIRS treatment were in the control group, while 60 patients who underwent RIRS with the assistance of a stone retrieval basket were in the observation group. The study compared various perioperative indicators (such as intraoperative blood loss, surgical duration, and hospital stay), as well as the stone clearance rates, inflammation levels, and postoperative complications at 3 days (short-term) and 30 days (long-term) after surgery. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and t-test was employed for inter-group comparisons. Chi-square test was used for inter-group comparisons of count data. Results:The operation time of the observation group was (78.26±10.54) min, and that of the control group was (70.65±8.67) min. The difference between the two groups was statistically significant ( P<0.05). There was no difference between the two groups in intraoperative bleeding, the first time to get out of bed after surgery and the postoperative hospital stay ( P>0.05). The stone expulsion time in the observation group was (16.38±4.22) d, while that in the control group was (18.96±5.10) d, the stone removal rates of the observation group at 3 days and 30 days after surgery were 88.33% and 95.00% respectively, while those of the control group were 73.33% and 83.33% respectively. There was a statistically significant difference between the two groups ( P<0.05). The stone expulsion time was shorter in the observation group compared to the control group, with a statistically significant difference ( P<0.05). There were no significant differences in postoperative inflammatory factors between the two groups( P>0.05). The incidence of postoperative complications in the observation group was 6.67%, and that in the control group was 20.00%. The difference between the two groups was statistically significant ( P<0.05). Conclusions:Stone basket removal combined with RIRS is safe and feasible, which can not only improve the stone clearance rate, but also reduce the incidence of postoperative complications without increasing the inflammatory reaction, and has a significant effect. However, the clinical application needs to strictly grasp the indications and avoid overtreatment in combination with the individual situation of the patients.

Objective : To investigate the expression and biological function of circular RNA(circRNA) hsa＿circ＿0002938 in gastric cancer. Methods : 45 pairs of tumor tissues and para-cancerous tissues from gastric cancer patients who underwent tumor reduction surgery at the hospital were collected. Human gastric cancer cells SGC-7901, BGC-823, HGC-27, MGC-803 and immortalized gastric mucosal epithelial cells GES-1 were routinely cultured. RT-qPCR was utilized to detect the expression of hsa＿circ＿0002938 in gastric cancer tissues and cells. Chi-square test was used to analyze its association with the clinicopathological characteristics of patients, and the Kaplan-Meier method was employed to assess the relationship between hsa＿circ＿0002938 expression levels and patient prognosis. The effects of hsa＿circ＿0002938 on the proliferation, migration and invasion abilities of gastric cancer cells were detected by CCK-8, scratch wound healing and Transwell assays. Bioinformatics was used to predict the miRNA and its downstream target genes that hsa＿circ＿0002938 might bind to. The competitive endogenous RNA regulatory network was constructed and the functions of the target genes were enriched. Results : The expression of hsa＿circ＿0002938 in gastric cancer tissues and cells was much higher than that in para-cancerous tissues and GES-1 cells(P<0.05). By contrast, patients in the high hsa＿circ＿0002938 expression group had significantly shorter 2-year progression-free survival than that in the low expression group after surgery(P<0.01). Moreover, knocking down the expression of hsa＿circ＿0002938 reduced the proliferative, migratory, and invasive abilities of gastric cancer cells(P<0.05). Bioinformatics predictive analysis showed that hsa＿circ＿0002938 could bind to hsa-miR-342-3p and hsa-miR-503-5p. The downstream target genes of miRNA were involved in several cancer-related pathways, like mitogen-activated protein kinase(MAPK), hippo and Wnt signaling pathway. Conclusion Hsa＿circ＿0002938, which is highly expressed in gastric cancer tissues and cells, is closely associated with poor patient prognosis. Knockdown of hsa＿circ＿0002938 inhibits the proliferation, migration, and invasion abilities of gastric cancer cells. The study reveals the potential role of hsa＿circ＿0002938 in the progression of gastric cancer, offering new insights into its prevention and treatment.

Transcatheter aortic valve replacement(TAVR)has become an important therapeutic approach for severe aortic stenosis.However,complications associated with TAVR cannot be overlooked,among which contrast agents induced acute kidney injury(AKI)is a common complication.To explore methods to reduce the occurrence of AKI,this article reports two cases of successful treatment of severe aortic stenosis by TAVR under pure echocardiographic guidance,both of whom were elderly women aged 75 and 69,respectively,and both were implanted with a Evolute Pro 26 mm valve.Postoperative echocardiography showed good valve positioning and function.
