[Research progress in signaling pathways related to treatment of functional dyspepsia with traditional Chinese medicine].

Functional dyspepsia(FD) is a prevalent functional gastrointestinal disease characterized by recurrent and long-lasting symptoms that significantly impact the quality of life of patients. Currently, western medicine treatment has not made breakthrough progress and mainly relies on symptomatic therapies such as gastrointestinal motility agents, acid suppressants, antidepressants/anxiolytics, and psychotherapy. However, these treatments have limitations in terms of insufficient effectiveness and safety. Traditional Chinese medicine(TCM) possesses unique advantages in the treatment of FD. Through literature search in China and abroad, it has been found that the mechanisms of TCM in treating FD is associated with various signaling pathways, and research on these signaling pathways and molecular mechanisms has gradually become a focus. The main signaling pathways include the SCF/c-Kit signaling pathway, 5-HT signaling pathway, CRF signaling pathway, AMPK signaling pathway, TRPV1 signaling pathway, NF-κB signaling pathway, and RhoA/ROCK2/MYPT1 signaling pathway. This series of signaling pathways can promote gastrointestinal motility, alleviate anxiety, accelerate gastric emptying, reduce visceral hypersensitivity, and improve duodenal micro-inflammation in the treatment of FD. This article reviewed the research on TCM's regulation of relevant signaling pathways in the treatment of FD, offering references and support for further targeted TCM research in the treatment of FD.

[Neuroendocrine differentiated prostate adenocarcinoma: Report of 23 cases and review of the literature].

OBJECTIVE: To study the clinical features and prognosis of neuroendocrine differentiated prostate adenocarcinoma (NED/AdPC). METHODS: We retrospectively analyzed the clinical data on 23 cases of NED/AdPC treated between 2005 and 2018, among which, 18 had lower urinary tract symptoms (LUTS). RESULTS: All the 23 patients were diagnosed with NED/AdPC, including 2 cases of AdPC initially diagnosed and confirmed with neuroendocrine differentiation in a second pathological diagnosis after androgen deprivation therapy (ADT). In addition to hormonal therapy for all the cases, 3 of the patients were treated by radical prostatectomy combined with adjuvant chemo- and radiotherapy, 13 by palliative transurethral bipolar plasmakinetic resection of the prostate (pTU-PKRP), of whom 2 underwent a second pTU-PKRP and chemotherapy for castration resistance, 2 with chronic renal insufficiency by percutaneous nephrostomy because of extensive pelvic metastasis, and the other 5 by ADT alone or in combination with radiotherapy. During the follow-up of 7 to 60 months, 2 of the patients died of cancer progression and 1 of pulmonary infection, while the others survived with effective control of the tumor. CONCLUSIONS: Long-term ADT may induce neuroendocrine differentiation in AdPC patients. For early-stage NED/AdPC, radical prostatectomy combined with adjuvant therapy is a main therapeutic option, while for advanced NED/AdPC, pTU-PKRP in combination with ADT may relieve LUTS and improve the patients' quality of life.

The effect of immediate surgical bipolar plasmakinetic transurethral resection of the prostate on prostatic hyperplasia with acute urinary retention.

In the present study, we evaluated the safety and efficacy of immediate surgical bipolar plasmakinetic transurethral resection of the prostate (PK-TURP) for patients with benign prostatic hyperplasia (BPH) with acute urinary retention (AUR). We conducted a retrospective analysis of clinical data of BPH patients who received PK-TURP. A total of 1126 BPH patients were divided into AUR (n = 348) and non-AUR groups (n = 778). After the urethral catheters were removed, the urine white blood cell (WBC) count in the AUR group significantly increased compared with the non-AUR group (P < 0.01). However, there was no significant difference in international prostate symptom score, painful urination, and maximal urinary flow rate. The duration of hospitalization of the AUR group was longer than that of the non-AUR group (P < 0.001). A total of 87.1% (303/348) patients in the AUR group and 84.1% (654/778) patients in the non-AUR group completed all of the postoperative follow-up visits. The incidence of urinary tract infection in the AUR group within 3 months after surgery was significantly higher than that in the non-AUR group (P < 0.01). The incidence of temporary urinary incontinence in the AUR group did not exhibit significant difference. During 3-12 months after surgery, there were no significant differences in major complications between the two groups. Multivariate regression analyses showed that age, postvoid residual, maximal urinary flow rate, diabetes, and hypertension, but not the presence of AUR, were independent predictors of IPSS post-PK-TURP. In conclusion, immediate PK-TURP surgery on patients accompanied by AUR was safe and effective.
