Renal thrombotic microangiopathy induced by targeted therapy combined with immunotherapy: a case report / 中华肾脏病杂志

Targeted therapy and immunotherapy have achieved great success in treating various solid and non-solid tumors, but the incidence of drugs-related adverse events is relatively high. The paper reports a case of renal thrombotic microangiopathy in an intrahepatic cholangiocarcinoma patient who underwent targeted therapy combined with immunotherapy. During the treatment, the tumor burden relieved continuously, but the patient developed proteinuria, edema and hypertension. The ADAMTS13 activity and inhibitors were normal, while the antiphospholipid antibody was positive. The patient was finally diagnosed as glomerular thrombotic microangiopathy with immune complex deposition by renal biopsy. After the cease of the antineoplastic agents and treatment with "cordyceps preparations" and "α-keto acids", the patient's blood pressure dropped to normal, her urine protein turnned to weakly positive, and her renal function remained stable.

Specification and grade of Saposhnikoviae Radix (Saposhnikovia divaricata) / 中草药·英文版

Objective: Saposhnikoviae Radix (Fangfeng in Chinese), the roots of Saposhnikovia divaricata, lacks commodity specification and grade standardization in the current market. This study investigated the existing specifications and grades of Saposhnikoviae Radix to provide a standardized scientific reference for its market use. Methods: Based on a textual research of Chinese herbal medicine from the Han Dynasty to the present, medicinal materials of different specifications and grades obtained from Saposhnikoviae Radix in the main producing areas of China were collected and the markets for these materials were investigated. Field investigations were performed in the major producing areas such as Northeast China, Hebei Province, and Inner Mongolia. Four major Chinese herbal medicine markets in China were investigated. Sensory indices were used to categorize the two specifications (wild and cultivated) according to the shape, color, texture, and cross-section. High-performance liquid chromatography was performed to determine the active components. Vernier calipers and measuring tape were used to measure the diameter and length, respectively, of 41 samples. Using Excel and the R Language software, cluster analysis and descriptive statistical analysis were performed to assist in the application of new specifications and grades based on physical characteristics, pharmacological activity, and chemical composition. Results: The two specifications (wild and cultivated) of Saposhnikoviae Radix were divided into three grades each based on the length and diameter. Prim-O-glucosylcimifugin, 5-O-methylvisamminoside, and the length of Saposhnikoviae Radix can be used as a basis for classifying the commodity specifications and grades. The specifications and grade standards of Saposhnikoviae Radix were established based on the following eight aspects: shape, surface characteristics, texture, cross section, taste, prim-O-glucosylcimifugin content, 5-O-methylvisamminoside content and length. Conclusion: The formulation of this standard stipulates the commodity specification level of Saposhnikoviae Radix. It is also suitable for the evaluation of commodity specifications in the process of production, circulation and use of Saposhnikoviae Radix.

Plant Pharmacophylogeny: Review and Future Directions / 中国结合医学杂志

Recently, the exploitation and utilisation of medicinal plant resources has increased significantly. The results of the studies have led to the identification of many active components, such as steroidal alkaloids, saponins, terpenoids, and glycosides, in various medicinal plants with different evolutionary levels. Moreover, research on the chemical classification, molecular phylogeny, and pharmacological activity of medicinal plants is increasing in popularity. Pharmacophylogeny is an interdisciplinary topic that studies the correlation between plant phylogeny, chemical composition, and curative effects (pharmacological activity and the traditional curative effect) of medicinal plants. In addition, it provides the basic tools to enable research and development of CM resources. This literature review, based on the genetic relationship between phytogroup and species, highlights the formation process, research content, applications, and future directions of pharmacophylogeny.

Effect of Heat-killed Lactobacillus casei DKGF7 on a Rat Model of Irritable Bowel Syndrome.

Non-viable bacteria, referred to as "paraprobiotics," have attracted attention as potentially safer alternatives to probiotics. The aim of this study was to investigate the efficacy of heat-killed Lactobacillus casei DKGF7 on the symptomatic improvement of irritable bowel syndrome (IBS) in a rat disease model and to elucidate the underlying mechanisms that contribute to the beneficial effects of heat-killed probiotics. Seven male Wistar rats were induced with IBS by restraint stress and administered heat-killed L. casei DKGF7 for four weeks and then compared with seven rats in the control group. Stool consistency measured four weeks after initial treatment was the primary outcome measure. To investigate the mechanism of action of the heat-killed bacteria on IBS, we measured serum corticosterone levels, inflammatory cytokines in colon tissue, and expression of tight junction proteins (TJPs) in the epithelium. The treatment group showed significantly better stool consistency scores than the control group at week 4, as well as at every measured time point (all p values < 0.05). The treatment group showed lower serum corticosterone levels, lower colonic inflammatory cytokine levels, and higher expression of TJPs compared with the control group. Paraprobiotics such as heat-killed L. casei DKGF7 can improve stool consistency in a rat IBS model, which may indicate a potential therapeutic strategy for IBS treatment.

Effects of infrasound with electroacupuncture on learning, memory and the CaMKⅡ-Tau protein signaling pathway / 中华物理医学与康复杂志

Objective:To observe the effect of electroacupuncture at the Baihui acupoint on learning and memory ability and on the calmodulin kinase (CaMK)Ⅱ-Tau protein signal pathway in rats exposed to infrasound, and to explore its mechanism.Methods:Forty-eight Sprague-Dawley rats were randomly divided into a blank group, an infrasound group, a Baihui group and a non-acupoint group, each of 12. The rats in the blank group were placed in an infrasound chamber without infrasound for 2 hours daily. Those in the other 3 groups were exposed to 8Hz, 130dB infrasound in the chamber for 2 hours daily for 7 consecutive days. The rats in the Baihui and non-acupoint groups were given electroacupuncture within 2 hours after the infrasound exposure at the Baihui acupoint or elsewhere respectively. The rats in the blank and infrasound groups were given the same grasping and fixation, but no electroacupuncture. On the 6th and 7th day of intervention, Morris water maze positioning and navigation experiments and spatial exploration experiments were used to quantify the rats′ spatial learning and memory ability. Nissl staining was used to observe any changes in the morphology of the neurons in the hippocampus of 6 rats in each group. The expression of phosphorylated calmodulin-dependent protein kinase II (P-CaMKⅡ) and phosphorylated Tau protein (P-Tau) in the hippocampus was also documented using western blotting.Results:After 6 or 7 days the average escape latency of the rats in the infrasound group was significantly longer than the blank group′s average. Platform quadrant time and distance ratios and the number of times crossing the platform area were also significantly lower. Compared with the infrasound group, the average escape latency of the Baihui group was significantly shorter, with the platform quadrant time and distance ratios and the number of times crossing the platform area significantly higher. After 7 days, the damage to hippocampal neurons among the rats in the infrasound group was significantly aggravated and the number of neurons was reduced significantly compared with the blank group. Compared with the infrasound group, significantly fewer neurons in the hippocampus were damaged in the Baihui group and the number of neurons had increased significantly. After the intervention the levels of P-CaMKⅡand P-Tau protein in the infrasound group had increased significantly compared with the blank group, but those levels in the Baihui group were significantly lower, on average.Conclusion:Electroacupuncture at the Baihui acupoint can improve the learning and memory ability of rats exposed to infrasound, and has some protective effect against infrasound brain damage. That may be due to its inhibiting Tau protein hyperphosphorylation in the hippocampus by reducing CaMKⅡ activity.

Isolation and identification of phosphatolytic bacteria in Paris polyphylla var. yunnanensis / 中国中药杂志

The wild resources of Paris polyphylla var. yunnanensis, a secondary endangered medicinal plant, are severely scarce. Introduction and cultivation can alleviate market demand. To screen phosphatolytic bacteria in the rhizosphere soil of P. polyphylla var. yunnanensis and provide data support for the development of high-efficiency microbial fertilizer, in this study, the dilution plate coating method was used to isolate and screen the phosphorus solubilizing bacteria with the ability of mineralizing organic phosphorus from the rhizosphere soil of wild and transplanted varieties of P. polyphylla var. yunnanensis in 10 different locations in Yunnan, Sichuan and Guizhou. After separation and purification, the phosphatolytic capacity was analyzed by qualitative and quantitative analysis. Combined with physiological and biochemical experiments, the strains were identified using 16 S rDNA sequencing analysis. Forty one strains were selected from the rhizosphere soil of P. polyphylla var. yunnanensis from 10 different habitats. Among them, 21 strains were obtained from the rhizosphere soil of the wild variety P. polyphylla var. yunnanensis and 20 strains were obtained from the rhizosphere soil of the transplanted variety. And significance analysis found that 41 organophosphate solubilizing strains had significant differences in their ability to solubilize phosphorus. The amount of phosphate solubilizing was 0.08-67.61 mg·L~(-1), the pH value was between 4.27 and 6.82. The phosphatolytic amount of strain Y3-5 was 67.61 mg·L~(-1), and the phosphorus increase amount was 57.57 mg·L~(-1). All 41 strains were identified as Gram-positive Bacillus. Combining physiological characteristic and phylogenetic trees, Bacillus mobilis Y3-5 was finally selected as the candidate rhizosphere phosphatolytic bacteria of P. polyphylla var. yunnanensis. The distribution of phosphorus solubilizing bacteria in the rhizosphere soil of P. polyphylla var. yunnanensis was different, and there were significant diffe-rences in phosphorus solubility. Organophosphate-dissolving strain Y3-5 is expected to be a candidate strain of P. polyphylla var. yunnanensis microbial fertilizer.

Effect of a Synbiotic Containing Lactobacillus paracasei and Opuntia humifusa on a Murine Model of Irritable Bowel Syndrome.

The administration of a combination of probiotics and prebiotics is expected to be a promising strategy for improving irritable bowel syndrome (IBS) symptoms. This study aimed to investigate the efficacy of a synbiotic containing Lactobacillus paracasei and Opuntia humifusa extract for symptomatic improvement of IBS in a murine model and to evaluate the mechanism underlying the beneficial effects of this synbiotic. A total of 20 male Wistar rats aged 8 weeks with IBS induced by restraint stress were assigned into four groups and administered L. paracasei as a probiotic and O. humifusa extract as a prebiotic for 4 weeks. The primary outcome was stool consistency at week 4. To evaluate the mechanism underlying the beneficial effects of the synbiotic, fecal microbial analysis was conducted, and the serum corticosterone levels, tumor necrosis factor-α (TNF-α) levels in the colon tissue, and expression of tight junction proteins were investigated. All three treatment groups showed significantly lower scores for stool consistency than the control group at week 4 (all p < 0.001). When compared with the control group, the synbiotic groups showed a significantly greater abundance of L. paracasei in fecal microbial analysis, lower serum corticosterone levels, lower TNF-α levels in the colon tissue, and higher expression of tight junction proteins. This novel synbiotic containing L. paracasei and O. humifusa extract can improve the stool consistency in a murine model of IBS. It may be a promising treatment option for IBS, and human studies are warranted.
