The brain-gut axis is an important channel to realize the functional integration of the central nervous system and the enteric nervous system between the brain and the intestine. It is the medium for the occurrence and development of depression and plays an important role in the pathogenesis of depression. From the perspective of modern medicine and TCM, based on the theory of "brain-gut axis", this article discussed the operation method and mechanism of acupuncture at abdominal ring acupoint in the treatment of depression in Zhuang medicine, in order to provide new ideas for acupuncture treatment of depression.

Background: Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. Methods: Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. Results: Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. Conclusions IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.

Atherosclerosis (AS) is a lipid-driven chronic inflammatory disease occurring at the arterial subendothelial space. Macrophages play a critical role in the initiation and development of AS. Herein, targeted codelivery of anti-miR 155 and anti-inflammatory baicalein is exploited to polarize macrophages toward M2 phenotype, inhibit inflammation and treat AS. The codelivery system consists of a carrier-free strategy (drug-delivering-drug, DDD), fabricated by loading anti-miR155 on baicalein nanocrystals, named as baicalein nanorods (BNRs), followed by sialic acid coating to target macrophages. The codelivery system, with a diameter of 150 nm, enables efficient intracellular delivery of anti-miR155 and polarizes M1 to M2, while markedly lowers the level of inflammatory factors and . In particular, intracellular fate assay reveals that the codelivery system allows for sustained drug release over time after internalization. Moreover, due to prolonged blood circulation and improved accumulation at the AS plaque, the codelivery system significantly alleviates AS in animal model by increasing the artery lumen diameter, reducing blood pressure, promoting M2 polarization, inhibiting secretion of inflammatory factors and decreasing blood lipids. Taken together, the codelivery could potentially be used to treat vascular inflammation.

Purpose:To investigate the prognostic value of P-glycoprotein(Pgp), mutant P53 protein and epidermal growth factor receptor (EGFR) expression in primary superficial transitional cell carcinomas(TCCs) of bladder.Methods:Specimens from 46 patients with untreated superficial bladder TCCs were analyzed for the expression of Pgp,mutant P53 and EGFR respectively and their clinical data were obtained by follow-up for over 3 years.Results:Pgp, mutant P53 protein and EGFR were positive in 45.7%,58.7% and 52.2% respectively. A strongly inverse relationship between the expression of Pgp, mutant P53 and EGFR and disease free survival (DFS)could be demonstrated by Kaplan Meier survival analysis. Multivariate analysis(Cox regression)indicated that DFS or recurrence was associated with overexpression of Pgp and mutant P53 protein, no significant correlation between EGFR overexpression and recurrence was found.Conclusions:Overexpression of Pgp, mutant P53 can be used as the important prognostic factor of recurrence of superficial TCCs.
