Both cathartic colon （CC） and cathartic-dependent constipation （CDC） are caused by the abuse of stimulant laxatives， while their concepts are not completely the same.Starting from the disease name of CC， this article traced the origin and evolution of the concept of CC， summarizes and compared the similarities and differences between CC， CDC， and slow transit constipation （STC）， and called for strict differentiation among the three.Furthermore， this article explored the specific contents of Western medicine clinical subtypes and traditional Chinese medicine （TCM） syndrome differentiation of CDC and delved into the TCM pathogenesis of CDC according to both literature and clinical practice.The relationship between clinical subtypes and TCM syndromes was established， and the syndrome characteristics of CDC of different clinical subtypes and TCM syndromes were summarized.The recommended prescriptions for corresponding syndromes were listed.A systematic CDC diagnosis and treatment approach of "clinical subtypes-syndrome differentiation-syndrome characteristics-recommended prescriptions" was thus formed.Additionally， the paper provides an overview of current research on CDC in both Western medicine and TCM contexts， identifies future research directions， and suggests research pathways for refining and advancing CDC studies.

Objective:To evaluate the efficacy and safety of transdermal delivery of compound glycyrrhizin injection as an adjunctive treatment for erythematotelangiectatic rosacea (ETR).Methods:This was a randomized controlled trial conducted from March to October 2024. At Sichuan Provincial People′s Hospital, 60 patients with newly diagnosed ETR were prospectively enrolled and randomized by a random number table into study group [ n=30; 6 male and 24 female; aged 18-60 (38.9±9.8) years] and control group [ n=30; 4 male and 26 female; aged 18-60 (35.7±10.1) years]. The study group received transdermal delivery of compound glycyrrhizin injection by a medium-frequency drug-delivery therapeutic apparatus together with oral azithromycin and hydroxychloroquine sulfate, whereas the control group received oral azithromycin and hydroxychloroquine sulfate. The efficacy evaluations were conducted at baseline and at weeks 2, 4, 6, and 8 post-treatment. Outcome measures included percentage of erythema area, stratum corneum hydration, transepidermal water loss (TEWL), clinician′s erythema assessment (CEA), erythema and telangiectasia scores, dermatology life quality index (DLQI), and efficacy rate. Adverse reactions during treatment were also recorded. Results:Compared with baseline, both groups exhibited significant reductions in percentage of erythema area, TEWL, CEA, erythema and telangiectasia score, and DLQI, and significant increases in stratum corneum hydration at each post-treatment time point (all P<0.05). After 2, 4, 6, and 8 weeks of treatment, the percentage of erythema area, erythema and telangiectasia scores in the study group were all lower than those in the control group, while the stratum corneum hydration level in the study group was higher than that in the control group (all P<0.05). After 4, 6, and 8 weeks of treatment, TEWL, CEA, and DLQI in the study group were all lower than those in the control group (all P<0.05). After 4 weeks of treatment, the efficacy rate in the study group was 56.7% (17/30), which was higher than that of the control group at 23.3% (7/30, P=0.046). After 6 weeks of treatment, the efficacy rate in the study group was 83.3% (25/30), higher than that of the control group at 50.0% (15/30, P=0.020). After 8 weeks of treatment, the efficacy rate in the study group was 86.7% (26/30), higher than that of the control group at 66.7% (20/30, P<0.001). No severe adverse reactions were observed in either group. Conclusion:Transdermal delivery of compound glycyrrhizin injection as an adjunctive treatment for ETR demonstrates favorable efficacy and good safety.

Objective:To analyze the composition and diversity characteristics of facial microbial communities in patients with moderate acne.Methods:This prospective study enrolled 30 patients with moderate acne [12 males, 18 females; aged 21-30 (25.4±2.5) years] from the Department of Dermatology, Sichuan Provincial People′s Hospital from March to July 2021. Thirty healthy controls [13 males, 17 females; aged 24-29 (25.2±1.4) years] were included during the same period. Facial skin swabs were collected from both groups. Total DNA was extracted, followed by PCR amplification, library preparation, and PE250 sequencing. After splicing, filtering, denoising, and chimera removal, amplicon sequence variants (ASV) feature tables and representative sequences were generated to compare microbial community differences between the two groups.Results:A total of 60 samples were sequenced, yielding 2 021 342 valid sequences. The 16S rRNA gene sequences were clustered into 8 379 ASV, with 589 ASV shared between the two groups, while 6 445 ASV were uniquely identified in healthy controls. At the phylum level, both groups showed similar dominant phyla: Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes. At the genus level, the acne group was predominantly colonized by Ralstonia (relative abundance 31.85%) and Staphylococcus (28.04%), while healthy controls exhibited more balanced distributions, primarily Staphylococcus (9.18%) and Enhydrobacter (7.37%). Alpha diversity analysis, Beta diversity analysis, and LefSe analysis revealed statistically significant differences in microbial communities between groups ( R2=0.157, P<0.001). The acne group showed lower microbial richness and evenness compared to healthy controls (both P<0.001). Conclusion:Patients with moderate acne exhibit microecological imbalance in facial microbial communities, characterized by reduced microbial richness and evenness.

Objective:To explore the efficacy and safety of the ballistic-ultrasound-negative pressure three-in-one energy platform (Trilogy) for micro-channel percutaneous nephrolithotomy (mini-PCNL).Methods:A retrospective analysis was conducted on the clinical data of 140 patients with upper urinary tract stones treated at Tianjin Medical University Second Hospital from February to October 2024. All patients underwent mini-PCNL and were divided into the holmium laser group and the Trilogy group based on the stone fragmentation equipment used during the procedure. There were 69 patients in the holmium laser group and 71 in the Trilogy group. The two groups had similar mean ages (55.1±10.2 years vs. 53.4±10.8 years), male patient proportions (50 cases, 72.5% vs. 50 cases, 70.4%), body mass indices (25.2±3.6 kg/m 2 vs. 25.3±4.0 kg/m 2), incidence rates of hypertension (29 cases, 42.0% vs. 31 cases, 43.7%), diabetes (15 cases, 21.7% vs. 12 cases, 16.9%), mean cumulative stone lengths (39.2±12.6 mm vs. 35.9±14.8 mm), total stone volumes preoperatively (6 184.3±3 653.5 mm 3 vs. 5 644.9±4 173.8 mm 3), mean CT values for stones (1 138.2±264.3 HU vs. 1 151.3±208.0 HU), stone locations (ureter 14 cases, 20.3% vs. 22 cases, 31.0%; kidney 48 cases, 69.6% vs. 39 cases, 54.9%; both ureter and kidney 7 cases, 10.1% vs. 10 cases, 14.1%), preoperative mean urinary white blood cell counts [9.6(3.6, 31.2) cells/HPF vs. 11.9(3.8, 34.5) cells/HPF], proportions of patients with preoperative urinary white blood cells (+ + + ; 23 cases, 33.3% vs. 25 cases, 35.2%), nitrite positivity rates (4 cases, 5.8% vs. 3 cases, 4.2%), and urine culture positivity rates (12 cases, 17.4% vs. 18 cases, 25.4%) showed no statistically significant differences. The proportion of patients with moderate or higher hydronephrosis in the holmium laser group was lower than that in the Trilogy group (32 cases, 46.4% vs. 47 cases, 66.2%, P=0.018). The holmium laser group utilized holmium laser lithotripsy, where stone fragments were either flushed out with a vortex or retrieved with a stone basket. The Trilogy group employed a three-in-one energy platform to break the stones. This device incorporated pneumatic ballistic, ultrasound, and negative pressure suction capabilities within the same metallic probe, allowing the stone to be fragmented into small pieces while simultaneously performing ultrasonic negative pressure stone clearance. The parameters for the three-in-one energy platform were adjusted based on intraoperative conditions, typically setting negative pressure at 30%-50%, ultrasound power at 80%-100%, ballistic power at 80%, and frequency at 8 Hz. During the stone fragmentation process, the ballistic device fragmented the stones while ultrasound further reduced larger fragments and removed them. Some fragments that were difficult to break could also be flushed out or retrieved with a stone basket. The efficiency of stone clearance (volume of stones cleared per unit time) was compared between the two groups, as well as the stone-free rates on postoperative day 1 and day 30. Stone clearance time was defined as the duration from the start of fragmentation to the placement of the nephrostomy tube. Changes in postoperative white blood cells, hemoglobin, and albumin levels compared to preoperative levels, as well as the incidence of Clavien-Dindo complications, were compared between the two groups. Equipment failure incidents were recorded (fiber fracture in the holmium laser group indicating it could not be used; probe fracture in the Trilogy group). Patients were sub-grouped based on stone CT values into CT ≥ 1 000 HU and CT < 1 000 HU categories to compare stone clearance efficiency between the two devices within each sub-group. In the CT≥1 000 HU sub-group, there were 51 cases in the holmium laser group and 54 in the Trilogy group, there were no significant differences in preoperative total stone volume (6 785.0±3 902.3 mm 3 vs. 5 678.1±4 297.7 mm 3). In the CT < 1 000 HU sub-group, there were 18 cases in the holmium laser group and 17 in the Trilogy group. There were no significant differences between the groups in preoperative total stone volume (4 482.2±2 110.6 mm 3 vs. 5 530.9±3 845.3 mm 3). Results:The overall stone clearance efficiency in the Trilogy group was higher than that in the holmium laser group (87.9±35.7 mm 3/min vs. 77.1±24.3 mm 3/min, P=0.038). There were no significant differences in residual stone volume before discharge [5.5(0, 84.0) mm 3 vs. 5.3(0, 175.0) mm 3], stone clearance time (79.4±43.2 min vs. 66.6±49.7 min), or the proportion of patients using stone baskets during the procedure (33 cases, 47.8% vs. 36 cases, 50.7%). Postoperative changes in white blood cells, hemoglobin, and albumin compared to preoperative levels were not significantly different [(4.1±2.9)×10 9/L vs. (3.3±2.2)×10 9/L; (-2.9±10.5) g/L vs. (-1.6±9.3) g/L; (-2.5±3.6) g/L vs. (-1.8±5.0) g/L] Furthermore, there were no statistically significant differences in equipment failure rates (1 case, 1.4% vs. 4 cases, 5.6%), stone-free rates (postoperative day 1: 43 cases, 62.3% vs. 47 cases, 66.2%; postoperative day 30: 50 cases, 72.5% vs. 53 cases, 74.6%), or Clavien-Dindo complication rates (grade Ⅰ: 11 cases, 15.9% vs. 8 cases, 11.3%; grade Ⅱ: 2 cases, 2.8% vs. 0 cases; grade Ⅲ: 1 case, 1.4% vs. 0 cases). In the CT ≥ 1 000 HU sub-group, the clearance time for the holmium laser was longer than that for Trilogy (93.3±41.0 min vs. 74.6±51.9 min, P=0.044), there were no significant differences in residual stone volume before discharge [6.3(1.6, 173.8) mm 3 vs. 4.5(0, 69.0) mm 3] between the two groups. In the CT < 1 000 HU sub-group, the overall stone clearance efficiency of the Trilogy group exceeded that of the holmium laser group (134.2±38.0 mm 3/min vs. 105.5 ± 7.1 mm 3/min, P=0.004), there were no significant differences between the groups in residual stone volume before discharge [0(0, 51.1) mm 3 vs. 16.3(0, 957.2) mm 3], or stone clearance time (40.2±18.1 min vs. 39.1±27.5 min). Conclusions:In mini-PCNL surgery, the stone fragmentation efficiency of the three-in-one lithotripsy energy platform is superior to that of the holmium laser, while the overall complication rate is comparable to that of the holmium laser.

Gynecological diseases are one of the important factors that threaten women's reproductive health.Endoplasmic reticulum(ER)stress is a stress response induced by the accumulation of unfolded or misfolded proteins in ER cavity when the female body is in a disease state,and the effects of different stress levels on the female reproductive system and the increase in the risk of female disease will vary greatly.Studies have shown that ER stress is closely related to the occurrence and development of gynecological diseases.Based on the relevant research reports at home and abroad in recent years,this paper summarizes the role of ER stress in several common gynecological diseases to provide new research ideas for preventing,diagnosing,and treating gynecological diseases.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

AIM:The objective of this study is to examine the expression of profilin 1(PFN1)in mice with di-abetic nephropathy and determine its association with immune cell infiltration.METHODS:This study presents an analy-sis of PFN1 expression and immune cell infiltration in patients with diabetic nephropathy,utilizing transcriptome expres-sion data from kidney tissue microarray.Additionally,the findings were validated in a diabetic nephropathy mouse model.Sixteen C57BL/6 mice were randomly assigned into two groups,namely the normal group and the model group,in an equal manner.The model group underwent the establishment of the diabetic nephropathy model through intraperitoneal injection of streptozotocin.Subsequently,the expression levels of CD11b,F4/80,CC chemokine receptor 4(CCR4),interleukin-1 receptor type I(IL-1R1),B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax)and caspase-3 in kidney tissue were assessed upon successful establishment of the diabetic nephropathy model.Furthermore,the overexpression of PFN1 was observed in a cellular model of diabetic nephropathy,and the protein expression levels of monocyte chemotactic pro-tein-1(MCP-1)and caspase-3 were assessed.RESULTS:The expression of PFN1 was found to be significantly in-creased in the GSE30122 dataset of transcriptome expression in kidney tissues affected by diabetic nephropathy(P＜0.01).This increase in PFN1 expression was found to be correlated with the presence of macrophages and T cells.Fur-thermore,the renal tissue of the diabetic nephropathy model group exhibited significant pathological changes.In this mod-el group,the expression levels of PFN1,CD11b,F4/80,CCR4,IL-1R1,Bax,Bcl-2,and caspase-3 were all significant-ly increased(P＜0.01).Overexpression of PFN1 could enhance the expression of MCP-1 and caspase-3 proteins.CON-CLUSION:Macrophages and Th17 cells were identified within the renal tissue of mice with diabetic nephropathy,con-comitant with an up-regulation in the expression of PFN1.This up-regulation was observed to facilitate the induction of apoptosis in the context of diabetic nephropathy.
