Objective To systematically evaluate the differences in clinicopathologic features and prog-nosis of colorectal cancer(CRC)between youth and middle-aged and elderly people.Methods The relevant literatures in Chinese and English databases before June 2024 were retrieved.The Stata 18 and RevMan5.3 softwares were used to perform the heterogeneity and sensitivity analyses as well as publication bias tests for the relevant outcome indicators.Results A total of 17 case-control studies were included,including a total of 6 817 patients with pathologically diagnosed CRC,among them 1 939 cases in the young group and 4 878 cases in the middle-aged and elderly group.The results of meta analysis showed that the proportion of family histo-ry in the young adult group(OR=3.09,95%CI:2.33-4.09),misdiagnosis rate(OR=4.40,95%CI:3.30-5.86),proportion of poorly differentiated carcinomas(OR=3.57,95%CI:2.73-4.67),proportion of mucin-ous adenocarcinomas and imprinted cell carcinomas(OR=3.41,95%CI:2.79-4.18),and proportion of TNM stage at diagnosis(stage Ⅲ-Ⅳ,OR=1.71,95%CI:1.44-2.02),incidence rate of lymph node metas-tasis(OR=1.92,95%CI:1.61-2.28),incidence rate of distant metastasis(OR=2.09,95%CI:1.53-2.86)were higher than those in the middle-aged and elderly group(all P<0.05);the CEA-positive rate at diagnosis(OR=0.68,95%CI:0.57-0.80)and 5-year survival rate(OR=0.24,95%CI:0.16-0.36)in the young group were lower than those in the middle-aged and elderly group(all P<0.05).The difference in the tumor diameter size(OR=1.32,95%CI:0.98-1.77)between the two groups was not statistically significant(P=0.07).Conclusion Compared with middle-aged and elderly CRC,young patients with CRC has a closer famil-ial correlation,may be more easily misdiagnosed clinically,its malignant degree would be higher,and the TNM stage in diagnosis is relatively late;in clinic the young population with CRC high risk could be appropriately relaxed in the age limit for screening.

Objective To analyze the prescription patterns of Professor Huang Feng,a nationally renowned traditional Chinese medicine(TCM)practitioner,in treating osteomyelitis using data mining methods.Methods Prescription data from effective medical records of osteomyelitis treated by Professor Huang Feng between January 2018 and December 2022 were collected and screened.Microsoft Excel,SPSS Modeler 18.0,and SPSS Statistics 25 were used to analyze the frequency and the distribution of properties,flavors,and meridian tropism of prescribed medications,along with association rule analysis and cluster analysis of high-frequency drugs.Results A total of 137 prescriptions involving 86 Chinese medicinals were included.Eighteen high-frequency medicinals(frequency＞30 times)were identified,namely Glycyrrhizae Radix et Rhizoma,Astragali Radix,Coicis Semen,Angelicae Sinensis Radix,Smilacis Glabrae Rhizoma,Achyranthis Bidentatae Radix,Bletillae Rhizoma,Rehmanniae Radix,Paeoniae Radix Alba,Dendrobii Caulis,Polygalae Radix,Lablab Semen Album,Corydalis Rhizoma,Angelicae Dahuricae Radix,Drynariae Rhizoma,Sanguisorbae Radix,Poria,and Mume Fructus.Most of the prescribed medicinals were neutral in nature,sweet,bitter,and pungent in flavor,and had the meridian tropism of liver,spleen,and lung meridians.Association rule analysis yielded 67 drug association rules,and the high-support combinations were the drug combinations of Astragali Radix respectively with Coicis Semen,Angelicae Sinensis Radix,Smilacis Glabrae Rhizoma and Achyranthis Bidentatae Radix,reflecting the compatibility principles of supplementing and invigorating qi-blood,activating blood circulation to resolve stasis,and draining dampness to remove toxins.Cluster analysis revealed three core clusters:Cluster 1 consisted of Glycyrrhizae Radix et Rhizoma,Astragali Radix,Coicis Semen,Smilacis Glabrae Rhizoma,Angelicae Sinensis Radix,Bletillae Rhizoma,Paeoniae Radix Alba,Angelicae Dahuricae Radix,Mume Fructus,Polygalae Radix and Sanguisorbae Radix;Cluster 2 consisted of Rehmanniae Radix and Dendrobii Caulis;Cluster 3 consisted of Achyranthis Bidentatae Radix,Lablab Semen Album,Corydalis Rhizoma and Poria.Conclusion For the treatment of osteomyelitis,Professor Huang Feng follows the principle of combining supporting healthy qi with eliminating pathogens,focuses on clearing damp-heat and pathogenic toxins accompanied by activating blood circulation to resolve stasis,and lays stress on adaptation to local condition and activating spleen-stomach to reinforce vital qi.

OBJECTIVE To systematically evaluate the efficacy and safety of compound danshen preparations combined with conventional chemical drug treatment for peptic ulcer （PU）， providing evidence-based guidance for clinical treatment of PU. METHODS Related clinical randomized controlled trials were collected from CNKI， VIP， Wangfang data， CBM， PubMed， Embase and Web of Science from their establishment date to September 30， 2023. The qualities of included literature were evaluated by Cochrane Systematically Evaluator Manual 5.1.0. Meta-analysis， sensitivity analysis and publication bias analysis were conducted with RevMan 5.3 software. RESULTS Totally 26 pieces of literature were included with total of 2 451 cases， including 1 243 cases in trial group （compound danshen preparations+conventional chemical drug treatment） and 1 208 cases in the control group （conventional chemical drug treatment）. In terms of effectiveness， trial group had significant advantages in ulcer healing rate [OR＝4.66， 95%CI （3.53， 6.15）， P＜0.000 01]， HP eradication rate [OR＝1.90， 95%CI （1.12， 3.22）， P＝0.02]，and pain relief rate [OR＝3.91， 95%CI （2.31， 6.61）， P＜0.000 01] than control group， while ulcer recurrence rate [OR＝0.22， 95%CI （0.15， 0.32）， P＜0.000 01] and serum levels of pepsinogen （PG）Ⅰ [SMD＝－1.92， 95%CI （－2.25， －1.58）， P＜0.000 01]， PGⅡ [SMD＝－3.88， 95%CI （－4.35， －3.41）， P＜0.000 01] and G-17 [SMD＝－3.44， 95%CI （－3.87， －3.00）， P＜0.000 01] were significantly lower than control group. In terms of safety， the main adverse reactions were abdominal discomfort， headache， dizziness， dry mouth， facial flushing， etc. There was no significant difference in the incidence of adverse reactionsbetween the two groups [OR＝1.08， 95%CI （0.75， 1.54）， P＝0.69]. Subgroup analysis of ulcer healing rate and HP eradication rate based on dosage form showed that HP eradication rate in the compound danshen pellet group was not significantly improved compared to the control group， with consistent results for the remaining outcomes. The sensitivity analysis showed that above results were stable. There was less possibility of publication bias in this study. CONCLUSIONS Compared with conventional chemical drug treatment alone， the combination of compound danshen preparations can effectively improve the clinical symptoms of PU patients with similar safety.

[Objective] To explore the clinical application of cutaneous ureterostomy-flap embedding in radical cystectomy plus urinary diversion. [Methods] The clinical data of 10 patients with bladder cancer treated with this method in our hospital during Feb.and May 2023 were involved.Cutaneous ureterostomy-flap embedding was used in urinary diversion.The stoma-free rate and stenosis rate of stomas within 1 year postoperatively, differences in renal function indicators 1 day before operation and 1 year after operation, urinary diversion-related complications within 6 months postoperatively, including hydronephrosis, urinary tract infections, renal stones were analyzed. [Results] All surgeries were successfully completed.At 1 year postoperatively, renal function indicators showed no significant difference compared to preoperative levels (P>0.05). At 6 months postoperatively, 1 patient developed renal stones, successfully treated with surgery; 2 had urinary tract infection, recovered after antibiotic treatment; 2 had mild unilateral hydronephrosis, alleviated with conservative management.At 1 year postoperatively, the catheter-free rate was 80%(8/10), with no worsening of hydronephrosis or occurrence of ureteral obstruction, and the stent placement duration ranged from 97 to 211 days, average (151.63±42.47) days.The ureteral stent was not removed in 2 patients within 1 year, so the stoma stenosis rate was 20%(2/10). [Conclusion] The application of flap embedding in urinary diversion following radical cystectomy is a simple and safe procedure, with few postoperative complications, high success rate of stent removal, and overall favorable outcomes.

Objective To observe the effect of Baduanjin exercise on depression,sleep quality and life quality of patients with breast cancer in the rehabilitation period.Methods A total of 76 breast can-cer patients in postoperative rehabilitation were randomly divided into an intervention group of 38 with 2 dropping out,and a control group of 38 with 3 dropouts.Both groups received routine nursing and rehabilitation after breast cancer surgery,while the intervention group additionally practised Baduanjin for 6 weeks.The Beck Depression Inventory-Ⅱ(BDI-Ⅱ-C),Pittsburgh Sleep Quality Index(PSQI)and Quality of Life Questionnaire Core 30(EORTC QLQ-C30)were used to evaluate both groups be-fore,as well as 3 and 6 weeks after intervention.Results After 3-week intervention,the average BDI-Ⅱ-C score,the total PSQI score and the scores of all dimensions except for the hypnotic drug dimen-sion of the intervention group was significantly lower than before treatment(P<0.05),and the control group at the same time point(P<0.05),while the scores of physical,emotional,cognitive,social and role function in EORTC QLQ-C30 were significantly higher than the latter(P<0.05).Three weeks lat-er,the average BDI-Ⅱ-C score,the total PSQI score and the scores of all dimensions except for the hypnotic drug dimension of the intervention group was significantly lower than before treatment(P<0.05),and the control group at the same time point(P<0.05),while the various scores of EORTC QLQ-C30 were significantly higher than the latter(P<0.05).Compared with after 3-week intervention,after 6-week intervention,the average BDI-Ⅱ-C score,the total PSQI score and the scores of its all dimensions except for the sleep disorder dimension of the intervention group decreased significantly,while all dimension scores of EORTC QLQ-C30 except the cognitive function dimension increased sig-nificantly(P<0.05 for all).Conclusion Baduanjin is feasible in improving the sleep and life quality of patients in the rehabilitation period after breast cancer surgery,and relieving their depression.

Objective To observe the correlation between apparent diffusion coefficient(ADC)of sacroiliac joint and spondyloarthritis research consortium of Canada(SPARCC)score in ankylosing spondylitis(AS)patients with different grade sacroiliac joint inflammation.Methods MR examinations of sacroiliac joint were prospectively performed in 35 AS patients(AS group)and 30 healthy controls(HC group).The grade of sacroiliac joint inflammation and SPARCC score in AS group were evaluated according to MRI findings,and the patients were then further divided into bone marrow oedema(BMO)subgroup(n=19)and non-BMO subgroup(n=16)according to whether BMO presented under articular surface or not,and ADC of sacroiliac joint(ADCsacroiliac)were measured.Receiver operating characteristic curve was drawn,the area under the curve(AUC)was calculated to evaluate the efficacy of ADCsacroiliac for assessing AS sacroiliac joint inflammation grade.Pearson correlation analysis was performed to analyze the correlation between ADCsacroiliac and SPARCC score in AS patients with different grade sacroiliac joint inflammation.Results ADCsacroiliac in BMO subgroup and non-BMO subgroup was(4.85±1.44)×10-4 and(4.30±0.64)×10-4 mm2/s,respectively,being not significantly different(P＞0.05)but both higher than that in HC group([3.32±1.36]×10-4 mm2/s,both P＜0.05).The sensitivity of ADCsacroiliac for assessing grade of sacroiliac joint inflammation in AS patients was 49.44％,51.94％,73.06％and 60.50％,with specificity of 75.00％,78.92％,83.33％and 66.67％,respectively,and AUC of 0.613,0.712,0.837 and 0.645,respectively.ADCsacroiliac was moderately-highly positively correlated with SPARCC score of AS patients with Ⅱ and Ⅲgrade sacroiliac joint inflammation(r=0.580,0.933,both P＜0.05),but no obvious correlation was detected between ADCsacroiliac and SPARCC score of AS patients with Ⅰ or Ⅳ grade sacroiliac joint inflammation(both P＞0.05).Conclusion ADCsacroiliac was positively correlated with SPARCC scores of AS patients with Ⅱ and Ⅲ grade sacroiliac joint inflammation,which could be regarded as a reliable quantitative parameter for monitoring sacroiliac joint BMO.

Objective To explore the impact of prolonged sitting on lumbar disc degeneration using MRI T1ρ and T2 mapping.Methods A total of 25 taxi drivers(prolonged sitting group)and 24 age-matched non-prolonged sitting volunteers(control group)underwent routine lumbar MRI,T1ρ,and T2 mapping.The differences of T1ρ and T2 values for different Pfirrmann grades of anterior annulus fibrosus(AAF),nucleus pulposus(NP),and posterior annulus fibrosus(PAF)were analyzed using Variance analysis,Spearman correlation test,and receiver operating characteristic(ROC)curve was drawn,with independent t-tests was used for between-group com-parisons.Results Statistically significant differences were observed in T1ρ and T2 values for all Pfirrmann Ⅰ-Ⅱ grades NP and Pfirrmann Ⅱ-Ⅳgrades AAF,NP,and PAF in both groups(P＜0.05).Both T1ρ and T2 values were negatively correlated with Pfirrmann grades.The area under the curve(AUC)of T1ρ values for NP at each Pfirrmann grade were 0.928,0.987,and 0.968,respectively,while the AUC of T2 values for NP were 0.777,0.966,and 0.975,respectively.The T1ρ and T2 values of L4/L5 NP and L5/S1 AAF,NP,and PAF were lower in the prolonged sitting group compared to the control group(P＜0.05).Conclusion T1ρ is superior to T2 mapping in detecting lumbar disc degeneration.Prolonged sitting is more likely to cause degeneration of L4/L5 and L5/S1 inter-vertebral discs.

AIM:To investigate the effects and mechanism of Xin-Tong-Tai granule on oxidized low-density li-poprotein(ox-LDL),intercellular adhesion molecule-1(ICAM-1)and vascular cell adhesion molecule-1(VCAM-1)in ApoE-/-mice with atherosclerosis(AS).METHODS:A total of 72 SPF-grade healthy male ApoE-/-mice aged 6～8 weeks were fed with high-fat diet for 12 weeks to replicate AS models,and 12 SPF-grade healthy male C57BL/6J wild mice were fed with ordinary diet as the control group.After the corresponding drugs were administered for 8 weeks,the body weight and general condition of mice in each group were observed.The serum levels of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)were detected by biochemi-cal kits.The pathological structures of aorta were observed by HE and oil red O staining.The levels of serum ox-LDL and aortic ICAM-1 and VCAM-1 were detected by ELISA.The protein levels of NADPH oxidase 4(NOX4),NOX subunit p22phox,inhibitor of κB kinase-α(IKK-α),IKK-β and nuclear factor-κB(NF-κB)in aorta were detected by Western blot.RESULTS:Compared with control group,the mice in model group showed increased body weight(P<0.05),dull and lo-cal shedding hair,slow grasping response,increased serum TC,TG and LDL-C levels,decreased serum HDL-C level(P<0.05),increased the levels of serum ox-LDL and aortic ICAM-1 and VCAM-1(P<0.05),and increased protein expres-sions of NOX4,p22phox,IKK-α,IKK-β and NF-κB in aorta(P<0.05).Compared with model group,the body weight of mice in each treatment group decreased(P<0.05),the hair loss and the response flexibility were also improved.The se-rum levels of TC,TG and LDL-C decreased and HDL-C increased(P<0.05).The levels of serum ox-LDL and aortic ICAM-1(except the low-dose Xin-Tong-Tai granule group)and VCAM-1 decreased(P<0.05).The protein levels of NOX4,p22phox,IKK-α,IKK-β and NF-κB in aorta decreased(P<0.05).HE and oil red O staining showed that typical AS plaques could be seen in blood vessels of the model group,and the red-stained areas were widely distributed.The above lesions were alleviated to different degrees in each treatment group compared with model group.CONCLUSION:Xin-Tong-Tai granule reduces the atherosclerotic plaque area of ApoE-/-mice induced by high-fat diet,decreased serum TC,TG and LDL-C levels,increased HDL-C level,decreased the levels of serum ox-LDL and aorta ICAM-1 and VCAM-1,and inhibited protein expression of NOX4,p22phox,IKK-α and IKK-β in the aorta,thereby attenuating AS.

Total mesorectal excision (TME) is the standard treatment for advanced mid- and low-rectal cancer. However, the associated surgical complications and subsequent impairment of organ function limit its application. In recent years, with advancements in neoadjuvant chemoradiotherapy and the implementation of immunotherapy, the pathological complete response (pCR) rate following neoadjuvant therapy for rectal cancer has significantly increased. This has raised questions about the necessity of performing TME in patients who achieve pCR. So as to, the clinical exploration of organ preservation strategies without radical surgery has been used in clinic. Current limited studies indicated that approaches such as watch & wait (W&W) or local excision have shown promising results in terms of long-term survival, and reduced surgical complications and functional impairment in some patients. However, challenges remain, including the difficulty in accurately assessing clinical complete response and the high rate of local recurrence, which could potentially compromise long-term survival. Further research into organ preservation strategies is needed, and careful consideration should be given to individual cases to prevent these strategies from becoming more of a “trap” than a “tart”.

Objective:To identify the clinical and pathological characteristics of adrenocortical carcinoma(ACC) with hypercortisolism and analyze the prognostic factors.Methods:Clinical data of ACC patients between January 2003 and December 2022 from Nanjing Drum Tower Hospital were collected retrospectively. Clinical and pathological characteristics were compared between ACC patients with hypercortisolism and nonfunctional ACCs. Kaplan-Meier method was used for survival analyses and Cox regression models were performed to analyze prognostic factors for ACC patients.Results:In 61 cases of ACC patients, the average age was (49.33±16.32) years. After a median follow-up of 77 months(95% CI 47.49-106.51 months), median overall survival and progression-free survival were 50 months(95% CI 20.44-79.56 months) and 29 months(95% CI 22.87-35.13 months), respectively. Among 36 patients with complete endocrinologic evaluations, 19(52.77%) were diagnosed with hypercortisolism. Compared with nonfunctional ACC, patients with hypercortisolism had more hypokalemia(42.11% vs 6.25%, P=0.022), capsular invasion(68.42% vs 25.00%, P=0.018), and distant metastases(73.68% vs 25.00%, P=0.007). Median overall survival and progression-free survival were significantly shorter than nonfunctional ACC(overall survival: 39 months vs 67 months, P=0.009; progression-free survival: 30 months vs 51 months, P=0.040) as well. Multivariate Cox regression analyses indicated that Ki67 index( HR=1.078, P=0.024) was an independent risk factor for overall survival. Hypercortisolism( HR=71.112, P=0.006), Ki67 index( HR=1.345, P=0.003), adjuvant therapy( HR=176.652, P=0.012), and operation( HR=0.020, P=0.003), were associated with disease progression. Conclusion:ACC accompanied by hypercortisolism is more prone to invasion and distant metastasis, resulting in shorter survival. Hypercortisolism is an independent prognostic factor for ACC patients.
