Clinical study on improving the function of female bladder in controlling urine by acupuncture Zhibian (BL54) under ultrasound guidance.

OBJECTIVE: To observe the effect of acupuncture Zhibian (BL54) on the function of the bladder in controlling urine in women under ultrasound. METHOD: 74 healthy subjects were randomly divided into deep acupuncture group of 37 cases and shallow acupuncture group of 37 cases. Under the guidance of ultrasound, the two groups of subjects were acupunctured at bilateral BL54. The deep acupuncture group was acupunctured to the pudendal nerve, and the shallow acupuncture group was acupunctured to the superficial fascia. Ultrasound was used to observe the peak systolic velocity (PSV), time average maximum velocity (TAMX), end diastolic velocity (EDV), pulsation index (PI), resistance index (RI) of the pudendal arteries, and bladder volume of two groups of subjects before and after acupuncture. The anatomical hierarchical structure of bilateral BL54 and score of Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) of all subjects was measured. RESULT: After acupuncture, the PSV, TMAX of the pudendal artery, bladder volume, and the Score of C-MASS Scale in the deep acupuncture group were higher than in the shallow acupuncture group (P < 0.05). The RI of the pudendal arteries in the shallow acupuncture group decreased compared to before acupuncture (P < 0.05). CONCLUSION: Acupuncture at the BL54 can increase the blood flow velocity of the pudendal artery, improve the function of the bladder in controlling urine in women, and different depths of acupuncture will have different therapeutic effects.

Efficacy of Warm Acupuncture Therapy Combined with Kegel Exercise on Postpartum Pelvic Floor Dysfunction in Women.

INTRODUCTION AND HYPOTHESIS: The objective was to observe the clinical efficacy of warm acupuncture combined with Kegel exercise in treating postpartum pelvic floor dysfunction in women. METHODS: A total of 70 primiparous women with postpartum pelvic floor muscle (PFM) injury were randomly divided into a combination group (n = 35, receiving warm acupuncture at Zhibian (BL54) acupoint and Kegel exercise) and a sham control group (n = 35, receiving sham warm acupuncture and Kegel exercise). Both groups were treated three times a week for 4 consecutive weeks. The recovery of PFM strength and changes in Urethral Rotation Angle (URA), Bladder Neck Descent (BND), and Retrovesical Angle (RVA) in pelvic floor ultrasound reports, the scores of pelvic floor dysfunction-related questionnaires, and the efficacy of urinary incontinence treatment of the two groups were compared before and after treatment. RESULTS: After treatment, the recovery rates of type I and II PFM strength, pelvic floor ultrasound parameters, pelvic floor dysfunction-related scale scores, and urinary incontinence treatment efficacy in the combination group were significantly better than those in the sham control group (p < 0.05). CONCLUSION: Warm acupuncture combined with Kegel exercise can significantly improve PFM strength and promote the recovery of postpartum pelvic floor function in women.

Tauroursodeoxycholic acid protects Schwann cells from high glucose-induced cytotoxicity by targeting NLRP3 to regulate cell migration and pyroptosis.

Diabetic peripheral neuropathy (DPN) is the most prevalent complication of type 2 diabetes mellitus (T2DM), and it seriously affects the quality of life of patients. Tauroursodeoxycholic acid (TUDCA) is a bile acid that plays a protective role against various diseases. However, the function of TUDCA in DPN progression needs to be elucidated. Hence, this study clarified the action of TUDCA on DPN development and explored its mechanism of action. Fecal samples were collected from 50 patients with T2DM or DPN. Schwann cells induced by high levels were constructed to simulate an uncontrolled diabetic state. Cell viability and migration were measured using the CCK-8 and wound-healing assays, respectively. Reactive oxygen species and pyroptosis were detected using flow cytometry. Parabacteroides goldsteinii and Parabacteroides distasonis levels were decreased in the feces of patients with DPN. TUDCA enhanced the viability and migration ability of high glucose-stimulated Schwann cells. In addition, Schwann cell pyroptosis stimulated by high glucose levels was inhibited by TUDCA. Furthermore, the protective roles of TUDCA in cell viability, migration ability, and pyroptosis of Schwann cells stimulated by high glucose were suppressed by the overexpression of NLRP3. TUDCA enhanced cell viability and migration and suppressed pyroptosis in Schwann cells stimulated by high glucose levels by modulating NLRP3 expression. Thus, TUDCA may be a promising drug for DPN therapy.

Cu(II)-Catalyzed ortho-Selective Aminomethylation of Phenols.

A Cu(II)-catalyzed ortho-selective functionalization of free phenols with trifluoroborates to afford Csp2-Csp3 coupling products under mild conditions has been developed. A variety of functional groups on the phenol and the potassium aminomethyltrifluoroborate substrates were found compatible, furnishing the corresponding products in moderate to excellent yields. A single-electron transfer radical coupling mechanism involving a six-membered transition state is proposed to rationalize the high levels of ortho-selectivity in the reaction. This protocol provides straightforward access to ortho-aminomethyl-substituted phenols, unnatural amino acids and other bioactive small molecules.

Encapsulation enhanced dimerization of a series of 4-aryl-N-methylpyridinium derivatives in water: new building blocks for self-assembly in aqueous media.

The construction of supramolecular systems in aqueous media is still a great challenge owing to the limited sources of building blocks. In this study, a series of 4-aryl-N-methylpyridinium derivatives have been synthesized. They formed very stable host-guest (1:2) complexes with CB[8] in water (binding constants up to 10(14) M(-2)) with the two guest molecules arranged in a head-to-tail manner and the complexes showed high thermostability, which was revealed by (1) H NMR and UV/Vis spectroscopic studies, ITC, and crystallographic analysis.
