OBJECTIVE: This study investigates the efficacy and mechanisms of Qingjie Fuzheng Granules (QFG) in inhibiting colitis-associated colorectal cancer (CAC) development via RNA sequencing (RNA-seq) and 16S ribosomal RNA (rRNA) correlation analysis. METHODS: CAC was induced in BALB/c mice using azoxymethane (AOM) and dextran sulfate sodium (DSS), and QFG was administered orally to the treatment group. The effects of QFG on CAC were evaluated using disease index, histology, and serum T-cell ratios. RNA-seq and 16S rRNA analysis assessed the transcriptome and microbiome change. Key pharmacodynamic pathways were identified by integrating these data and confirmed via Western blotting and immunofluorescence. The link between microbiota and CAC-related markers was explored using linear discriminant analysis effect size and Spearman correlation analysis. RESULTS: Long-term treatment with QFG prevented AOM/DSS-induced CAC formation, reduced levels of interleukin (IL)-1β, tumor necrosis factor-alpha (TNF-α), IL-6, and interferon γ (IFN-γ), and increased CD3⁺ and CD4⁺/CD8⁺ T cells ratio, without causing hepatic or renal toxicity. A 16S rRNA analysis revealed that QFG rebalanced the Firmicutes/Bacteroidetes ratio and mitigated AOM/DSS-induced microbiota disturbances. Transcriptomics and Western blotting analysis identified the nucleotide-binding oligomerization domain-containing protein 2 (NOD2)/nuclear factor kappa-B (NF-κB) pathway as key for QFG's treatment against CAC. Furthermore, QFG decreased the abundance of Bacilli, Bacillales, Staphylococcaceae, Staphylococcus, Lactobacillales, Aerococcus, Alloprevotella, and Akkermansia, while increasing Clostridiales, Lachnospiraceae, Lachnospiraceae_NK4A136_group, Ruminococcaceae, and Muribaculaceae, which were highly correlated with CAC-related markers or NOD2/NF-κB pathway. CONCLUSION By mapping the relationships between CAC, immune responses, microbiota, and key pathways, this study clarifies the mechanism of QFG in inhibiting CAC, highlighting its potential for clinical use as preventive therapy.

Pancytopenia is one of the serious complications of Graves disease, and its clinical treatment is quite challenging. Based on traditional Chinese medicine theory and combining with literature reports and clinical practice in China, we discuss the etiology, pathogenesis, and syndromes-based treatment of pancytopenia, hoping to open up new treatment approaches, guide clinical practice, and improve treatment effectiveness.

Objective:To investigate the effects of finasteride combined with tamsulosin hydrochloride administered during the perioperative period on glandular microvessel density in patients with benign prostatic hyperplasia.Methods:Ninety patients with benign prostatic hyperplasia who received treatment in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from August 2017 to August 2019 were included in this study. They were randomly assigned to receive either oral tamsulosin hydrochloride alone (control group, n = 45) or oral finasteride combined with tamsulosin hydrochloride (observation group, n = 45) during the perioperative period of transurethral resection of the prostate. All patients received 6 weeks of medication. Clinical efficacy, adverse reactions, and urodynamic indexes, glandular microvessel density, International Prostatism Symptom Score, bother score, and urine color/degree of haematuria score pre- and post-treatment were compared between the two groups. Results:The maximum urinary flow rate in each group significantly increased 6 weeks after treatment compared with before treatment. The detrusor pressure and residual urine volume in each group decreased 6 weeks after treatment compared with before treatment. After 6 weeks of treatment, the maximum urinary flow rate was significantly higher in the observation group than in the control group [(15.63 ± 2.26) mL/s vs. (13.14 ± 2.23) mL/s], and residual urine volume was significantly lower in the observation group than in the control group [(29.19 ± 4.81) mL vs. (32.25 ± 5.52) mL, t = 5.26, 2.80, both P < 0.05). International Prostatism Symptom Score measured 6 weeks after treatment and urine color/degree of haematuria score measured 1 week after treatment were (12.09 ± 2.17) points and (1.51 ± 0.27) points, respectively in the observation group, which were significantly lower than those in the control group [(14.28 ± 2.22) points, (2.03 ± 0.38) points, t = 4.73, 7.48, both P < 0.05]. Factor VIII related antigen- and CD34-positive glandular microvessel density values in the observation group were (14.74 ± 3.05) counts/visual field and (19.41 ± 3.07) counts/visual field, respectively, which were significantly lower than those in the control group [(18.08 ± 3.16) counts/visual field, (22.27 ± 3.16) counts/visual field, t = 5.10, 4.35, both P < 0.05]. The incidence of postoperative hematuria was significantly lower in the observation group than in the control group [15.56% (7/45) vs. 35.56% (16/45), χ2 = 4.73, P < 0.05]. Conclusion:Compared with tamsulosin hydrochloride alone, finasteride combined with tamsulosin hydrochloride administered during the perioperative stage can greatly improve the urodynamic indexes of patients with benign prostatic hyperplasia, reduce microvessel density value, International Prostatism Symptom Score, bother score, and decrease the incidence of hematuria. The combined therapy provides a novel idea for preventing perioperative bleeding in patients with benign prostatic hyperplasia.

OBJECTIVE：To investigate the correlation of storage life and effective composition content with color value of Carthamus tinctorius ，and to provide reference for the quality evaluation of C. tinctorius with different years of storage. METHODS：Using 24 batches of C. tinctorius from same place of production with different years of storage （0，1，2 years，8 batches each type ）as samples ，the contents of hydroxysafflor yellow A （HSYA）and kaempferol were determined by HPLC. Color value [lightness value （L*），red-green value （a*），yellow-blue value （b*）] were determined by spectrophotometer. SPSS 19.0 statistical software was used to analyze the correlation of storage life and effective composition content with color value. RESULTS：Kaempferol content was still high after 1 year or 2 years of storage （0.161％，0.061％，respectively）. However ，the content of HSYA decreased with the prolongation of the storage life （the average content of HSYA were 2.46％，1.58％，and 1.51％ after storage 0，1 and 2 years，respectively），and the color of the drug became darker （a* value decreased ）. Results of correlation analysis showed that the content of HSYA was positively associated with color value L*，a*（r＝0.430，0.781，P＜0.05 or P＜0.01）；the content of HSAY was negatively associated with storage life （r＝－0.777，P＜0.01）. There was no correlation between the remaining variables （P＞0.05）. CONCLUSIONS ：The longer the storage life ，the darker the color and the lower the content of HSYA ，so it is not suitable for over year and multiyear preservation.

Objective To explore the roles of glycogen synthase kinase-3β (GSK-3β) in cognitive dysfunction and emotional alterations after rat's chronic cerebral ischemia.Methods 51 SD rats were randomly divided into sham group (sham group,n=17),chronic cerebral ischemia group (2VO group,n=17),chronic cerebral ischemia group + LiCl group (2VO + LiCl group,n=17),according to the table of random number.All groups were intraperitoneally injected with LiCl or saline on 3rd,7th,14th,21 st and 28th day,and then produced the chronic cerebral ischemia models.On the 28th day after model,the spatial learning and memory,fear memory,and anxiety emotion were detected.Results The Morris water maze test showed that 2VO group spent longer latent time searching and finding the platform than sham group (4th day P＜0.01,3rd,5th,6th,7th day P＜0.05).2VO+LiCl group spent shorter latent time than 2VO group (4th day P＜0.01,5th,6th,7th day P＜0.05).After removing the platform,2VO group spent longer time arriving the former location than sham group (P＜0.05).And 2VO+LiCl group spent dramatically different time compared to 2VO group (P＜0.01).Step-down test showed 2VO group spent shorter latent time than sham group (2VO group:(41.00±1.87)s,sham group:(44.55±2.77)s) (P＜0.05).2VO+ LiCl group spent dramatically longer latent time compared to 2VO group (2VO +LiCl group:(43.40± 1.35)s) (P＜ 0.05).2VO group made much more mistakes times than sham group (P＜0.05).2VO+LiCl group made dramatically less mistakes times compared to 2VO group (P＜0.05).The elevated plus maze test showed 2VO group had much less ratio of retention time in open arms (among total arms retention time) than sham group (2VO group:(0.23± 0.01),sham group:(0.25± 0.01)) (P＜ 0.01).2VO + LiCl group had much larger ratio than 2VO group (2VO + LiCl group:(0.24±0.01),P＜0.05).2VO group had much less ratio of entry times in open arms (among total arms entry times) than sham group (P＜0.01).2VO+LiC1 group had much larger ratio than 2VO group(P＜0.05).Conclusion Chronic cerebral ischemia can lead to deterioration of learning and memory,and anxiety emotion for rats.However,inhibition of GSK-3β can ameliorate these alterations.

Objective To explore the correlationship between Cystatin C and the cognitive dysfunction, encephalatrophy and the cerebral perfusion in Alzheimer's disease ( AD ) patients, and to analyze the probable mechanisms of the Cystatin C level alterations. Methods For the 61 male and 55 female AD patients,the levels of Cystatin C,Urea,Cr andβ2?microglobulin were detected by biochemistry analysis.The hypocampus volume and Ev?ans index were measured by MRI imaging. The cerebral perfusion was evaluated by magnetic resonance perfusion imaging of arterial spin labeling technique and image processing. The cognitive level of AD patients was done by MMSE scale and MoCA scale. Results The Cystatin C levels in serum of male AD patients were dramatically dif?ferent from female AD patients(male:(0.95±0.20)mg/L,female:(1.32±0.41)mg/L)(P=0.04). For male AD patients,age and Cystatin C had a correlationship among the hypocampus volume((6157.14±355.58)mm3),Evans index(0.33±0.02),MMSE score(21.66±7.97),and MoCA score(21.96±6.19)(age:P=0.040,0.049,0.035, 0.039;Cystatin C:P=0.035,0.038,0.037,0.035),but for female only age((79.52±8.82)years) had a correla?tionship with the hypocampus volume((6319.53±377.74)mm3),Evans index(0.31±0.02),MMSE score(22.93± 6.22),and MoCA score(23.41±8.20)(P=0.044,0.045,0.047,0.046). For male AD patients,the marked correla?tionship was showed between Cystatin C and the index of cerebral perfusion(P=0.034),but for female patients, there's no correlationship(P=0.086) . Conclusion The Cystatin C level is distinctly different in male and female AD patients. The Cystatin C level in male AD patients maybe be an index to predict the degree of the cognitive dys?function and the level of cerebral perfusion.

Objective To explore the roles and related mechanisms of Protein Phosphatase 2A(PP2A) in cognitive dysfunction after the chronic cerebral ischemia.Methods 70 male Sprague Dawley rats in clean degree were divided into sham group,chronic cerebral ischemia group (Bilateral carotid arteries occlusion,2VO),and chronic cerebral ischemia group with PP2A activation group(2VO+aPP2A).The rats were injected intraperitoneally with 1.88 μmol/ml sodium selenate(15 μmol · kg-1 · d-1) or equal volume of saline for 4 weeks.After one month,the chronic cerebral ischemia models were reproduced by the occlusion of bilateral common caroid artery.Then the abilities of learning and memory were tested by Morris water maze,electrophysiological indices were recorded to analyze the LTP changes,and destribution of synaptic vesicles was observed by electron microscope.Results Morris water maze test showed that the 2VO group had significantly longer latent time than sham group in searching platform(P＜0.05),and the 2VO+aPP2A group had dramatically shorter latent time (P＜0.01) than that of 2VO group.Then removing platform to test the rats memory,the data showed that 2VO group spent markedly longer time than sham group to reach the location of the former platform (sham group:(14.50±1.98)s ; 2VO group:(17.30±2.11) s) (P＜0.01),and the 2VO+aPP2A group((15.09± 1.45) s) spent dramatically shorter latent time(P＜0.05) than that of 2VO group.The electrophysiological data showed that 2VO group had the noticeably smaller field excitable postsynaptic potential slope (fEPSP) slope ratio between pre and post of the high frequency stimulations (Long-term potential,LTP) than sham group(sham group:1.69±0.27; 2VO group:2.02±0.137) (P＜0.01),and the 2VO+aPP2A group(1.86±0.19) had strikingly higher ratio than that of 2VO group(P＜0.01).The electromicroscope observation showed that presynaptic vesicles density of 2VO was remarkably lower than that of sham group (sham group:(4.51±0.29) /μm2 ; 2VO group:(2.02±0.14) /μm2) (P＜0.01),and presynaptic vesicles density of 2VO+aPP2A group((3.58±0.50) /μm2) was noticeably higher than that of 2VO group(P＜0.01).Conclusion Activating PP2A can prevent the cognitive dysfunction after chronic cerebral ischemia through regulating LTP and synaptic vesicle density.And PP2A is probably a potential target for preventing and treating the cognitive dysfunction after chronic cerebral ischemia.

Objective To discuss the causes leading to dissatisfying result after operation therapy for BPH.Methods 42 patients who had not acquired satisfying result after operation therapy for BPH were underwent the urodynamic examination.Results 42 patients were classified into two groups according to their different symptoms:difficuhy to void,32 case8,including 8 cases with low contractifity of detrusor,and 24 cases with Madder outflow obstruction(BOO);incontinence,10 eases,including 6 cases of urgency incontinence and 4 cases of stress incontinence.Condusion We can see that the causes leading to dissatisfying resuh after operation for BPH are mainly the dysfunction of detmsor and BOO,and the result of urodynamic examine can guide us the causes and the next therapy.

Objective To evaluate the morbidity of the post-prostatectomy incontinence of supra-pubic transvesical prostatectomy(SPP) and transurethral resection of prostate(TURP). Methods One hundred and thirtyfive patients were divided into two groups. 82 patients underwent SPP and 53 patients underwent TURP. We ob-served the morbidity and the time lasting of post-prostatectomy incontinence, the severity of post-prostatectomy in-continence as evaluated by Stamey incontinence grading system,patients who had more than one week postoperativeincontinence were received urodynamic tests,then we got the information of their incontinence types. Results We found that patients who underwent SPP had higher morbidity, severity and time lasting than those who underwent TURP. SPP group had much more morbidity of stress incontinence than TURP group, but the same morbidity of ur-gent incontinence after operation as the later. Conclusion TURP may be better than SPP in consideration of the post-prostateetomy incontinence. SPP group has more stress incontinence and it may be caused by complete resection of prostate and damnifieation of the mucous membrane of membranous urethra.
