Efficacy of Baishao Luoshi decoction on synaptic plasticity in rats with post stroke spasticity.

OBJECTIVE: To evaluate the efficacy of Baishao Luoshi decoction (, BD) on synaptic plasticity in rats with post stroke spasticity (PSS), and to study the mechanism behind the action. METHODS: The PSS model of rat was established by middle cerebral artery occlusion (MCAO). The neurological deficit symptoms were evaluated by modified neurological deficit score (mNSS). Muscle tension were evaluated by Modified Ashworth score (MAS). Transmission electron microscopy (TEM) was used to observe the synaptic ultrastructure. The expression of synaptic plasticity-related protein brain derived neurotrophic factor (BDNF), growth associated protein-43 (GAP43), synaptophysin (p38) and microtubule-associated protein 2 (MAP2) in the brain tissue around the infarct were detected by Western blotting. RESULTS: We found that mNSS were significantly improved and limb spasticity was ameliorated treated by BD. The thickness of postsynaptic density and the synaptic curvature increased significantly. The expression of synaptic plasticity-related protein BDNF, GAP43, p38, MAP2 in the brain tissue around the infarct were raised remarkably after treated by BD. CONCLUSIONS: Alleviating PSS by BD may be related to rescuing the synaptic plasticity, which provides a probable new therapeutic method for PSS.

Characteristics, origin, and processing of Poria in Qing Dynasty Palace:evidence of both historical relics and documents / 中国中药杂志

Poria(Fu Ling) is a bulk traditional Chinese medicine(TCM)with a long history and complex varieties. The royal medical records of the Qing Dynasty include multiple medicinal materials of Fu Ling, such as Bai Fu Ling(white Poria), Chi Fu Ling(rubra Poria), and Zhu Fu Ling(Poria processed with cinnabaris). The Palace Museum preserves 6 kinds of specimens including Fu Ling Ge(dried Poria), Bai Fu Ling, Chi Fu Ling, Zhu Fu Ling, Bai Fu Shen(white Poria cum Radix Pini), and Fu Shen Mu(Poria cum Radix Pini). After trait identification and textual research, we found that Fu Ling Ge was an intact sclerotium, which was processed into Fu Ling Pi(Poriae Cutis), Bai Fu Ling and other medicinal materials in the Palace. The Fu Ling in the Qing Dynasty Pa-lace was mainly from the tribute paid of the officials in Yunnan-Guizhou region. The tribute situation was stable in the whole Qing Dynasty, and changed in the late Qing Dynasty. The cultural relics of Fu Ling in the Qing Dynasty Palace confirm with the archival documents such as the royal medical records and herbal medicine books, providing precious historical materials for understanding Fu Ling in the Qing Dynasty and a basis for the restoration of the processing of the Fu Ling in the Qing Dynasty Palace.

Effects of Buyang Huanwu Decoction on Intestinal Barrier, Intestinal Flora, and Trimethylamine Oxide in Rats with Heart Failure / 中国结合医学杂志

OBJECTIVE@#To explore the mechanisms of Buyang Huanwu Decoction (BYHWD) modulating the gut microbiome and trimethylamine oxide (TAMO) to exert cardioprotective effects.@*METHODS@#Ligation of the left anterior descending coronary artery was performed in rats to induce heart failure (HF). Except for the sham-operation group (n=10), 36 operation-induced models were randomized into 3 groups using a random number table (n=12 in each group): the model group, the BYHWD group (15.02 g/kg BYHWD), and the positive group (4.99 g/kg metoprolol succinate). After 4-week treatment (once daily by gavage), echocardiography was applied to evaluate the cardiac function and the Tei index (the ratio of ventricular isovolumic contraction time (IVCT) and isovolumic diastolic time (IVRT) to ejection time (ET)) was calculated; hematoxylin-eosin (HE) staining was observed to characterize the pathology of the myocardium and small intestinal villi. D-lactic acid was detected by an enzyme-linked immunosorbent assay (ELISA). Expressions of occludin, claudin-1, and zonula occludens (ZO-1) were detected by Western blot. 16S ribosomal ribonucleic acid (16S rRNA) sequencing was used to explore the changes in the intestinal flora. TMAO was detected via liquid chromatography-tandem mass spectrometry (LC-MS/MS).@*RESULTS@#In the echocardiography, the Tei index was considerably lower in the positive and BYHWD groups compared with the model group (P<0.05). Besides, BYHWD improved the pathology of myocardium and small intestine of HF rats and lowered the D-lactic acid content in the serum, when compared with the model group (P<0.05). BYHWD also improved the expression of occludin and claudin-1 (P<0.05); in the gut microbiota analysis, BYHWD slowed down modifications in the structure distribution of gut microbiota and regulated the diversity of intestinal flora in HF rats. The content of TMAO in the serum was significantly lowered by BYWHT compared with the model group (P<0.05).@*CONCLUSION@#BYHWD may delay progression of HF by enhancing the intestinal barrier structure, and regulating intestinal flora and TAMO.

Activation of vitamin D receptor inhibits Tau phosphorylation is associated with reduction of iron accumulation in APP/PS1 transgenic mice.

Vitamin D deficiency and iron accumulation are prevalent in the brains of Alzheimer's disease (AD) patients, however, whether Vitamin D has a role in the regulations of iron metabolism in the condition of AD remains unknown. Our previous studies revealed that vitamin D deficiency promotes ß-amyloid (Aß) deposition in the APP/PS1 mouse brains, while supplemented with a specific agonist of vitamin D receptor (VDR), paricalcitol (PAL), significantly reduced Aß production via promoting the lysosomal degradation of ß-site APP cleavage enzyme 1 (BACE1). In this study, our data suggested that activation of VDR by PAL significantly reduced the iron accumulation in the cortex and hippocampus of APP/PS1 mice through downregulation of Transferrin receptor (TFR) by reducing iron-regulatory protein 2 (IRP2) expression. Furthermore, activation of VDR effectively reduced the phosphorylations of Tau at Ser396 and Thr181 sites via inhibiting the GSK3ß phosphorylation (Tyr216). Taken together, our data suggest that activation of VDR could inhibit the phosphorylations of Tau possibly by repressing the iron accumulation-induced upregulation of GSK3ß activity in the brains of APP/PS1 mice. Thus, activation of VDR may be an effective strategy for treating AD.

Risk factors of acute renal impairment after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Acute renal impairment (ARI) is a major complication after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for cancer patients with peritoneal metastases. This study aimed to investigate the incidence and identify the risk factors of post-HIPEC creatinine increased. METHODS: From April 2015 to December 2019, demographic and perioperative data of 169 patients undergoing CRS/HIPEC with a preoperative creatinine level <1.5 mg/dL were retrospectively reviewed. Renal impairment was defined according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. The risk factors of creatinine increased were analyzed using univariate and multiple logistic regression analyses. RESULTS: Among the 169 enrolled patients, 21 (12.4%) had postoperative creatinine increased (ARI group) and 148 (87.6%) did not (non-ARI group). Significantly more of the ARI group received a cisplatin HIPEC regimen than the non-ARI group (71.4 vs. 37.8%, p = 0.004). Multiple logistic regression analysis revealed that the patients who received a cisplatin HIPEC regimen (adjusted odds ratio [AOR] = 11.38, p < 0.001) and peritoneal dialysis solution as HIPEC perfusate (AOR = 7.07, p = 0.002) were more likely to develop post-HIPEC creatinine increased. CONCLUSIONS: Identifying the risk factors of post-HIPEC creatinine increased can help to improve patient selection, a dose of HIPEC regimens modification and perioperative care. We also identified the detrimental renal effect of peritoneal dialysis solution as HIPEC perfusate. More prospective studies are warranted to confirm these findings.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for peritoneal malignancy: preliminary results of a multi-disciplinary teamwork model in Asia.

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an emerging surgical procedure for peritoneal carcinomatosis (PC). CRS/HIPEC is a complicated treatment that requires multi-disciplinary teamwork (MDT), which may be lacking when establishing a CRS/HIPEC programme. Herein, we report our preliminary treatment outcomes with the early implementation of an MDT model for CRS/HIPEC. METHODS: From April 2015 to December 2016, 45 patients with a diagnosis of PC who received CRS/HIPEC were reviewed retrospectively in a single institution in Taiwan. RESULTS: Among the 45 patients, CRS was mainly performed by laparotomy (n = 42), and only three patients with limited PC underwent laparoscopic CRS. The first 13 patients received treatment before the MDT had been established (group 1), and the other 32 patients were treated after the MDT had been established (group 2). The highest peri-HIPEC body temperature in group 2 was significantly lower than that in group 1 (36.8 °C vs. 37.5 °C, p < 0.001). Overall, eight patients experienced major complications. The trend of a lower major complication rate was observed after the MDT model had been implemented (30.7% in group 1 vs. 12.4% in group 2, p = 0.202). Pre-CRS/HIPEC abdominal pain significantly increased the risk of post-operative major complications (p = 0.017). CONCLUSIONS: Our experience suggests that the early implementation of an MDT model when establishing a CRS/HIPEC programme at a single institution may result in a higher complete cytoreduction rate and lower major complication rate, and also shorten the learning curve of this complicated procedure.

Acupuncture therapy results in immediate bronchodilating effect in asthma patients.

BACKGROUND: According to previous data on asthma in the English literature, there are some results that show encouraging effects of acupuncture improving pulmonary function in asthma patients. We designed a prospective randomized crossover controlled study to determine the efficacy of acupuncture in asthma patients. METHODS: Eighteen asthma patients with bronchodilator response >20% improvement of forced expiratory volume in 1 second (FEV1) were initially randomly assigned to receive 1 performance of real acupuncture (RA) or sham acupuncture (SA) in a blinded manner. After a washout period, the patients were crossed over. Spirometry was done and recorded before and after acupuncture. RESULTS: Sixteen of 18 patients completed the study. The mean (+/-SD) FEV1 values before and after RA were 1.52 +/- 0.45L and 1.67 +/- 0.40L, respectively (p < 0.001). The mean (+/-SD) FEV1 values before and after SA were 1.49 +/- 0.40L and 1.49 +/- 0.41L, respectively (p = 0.838, not significant). The percentage change in FEV1 values after RA was better than after SA (RA, 11.57 +/- 8.11%; SA, 0.32 +/- 7.76%; p = 0.003), while the bronchodilator response of FEV1 from simple inhalation bronchodilator was better than that for RA (p < 0.001). CONCLUSION: In asthma patients, acupuncture treatment may result in immediate improvement of FEV1, but the degree of improvement is less than that from inhalation bronchodilator.
