MethodA syndrome questionnaire was developed to collect the general data and four diagnosis information on 296 patients with urolithiasis who were treated from September 2021 to September 2022. Tongue images, pulse images, symptoms, and signs were statistically analyzed, and the characteristics of syndrome were explored by association rule analysis, factor analysis, and cluster analysis. Result① In the distribution of tongue images, the single tongue images with a frequency of more than 20% were white fur, red tongue, thick fur, greasy fur, and yellow fur. In the distribution pf pulse images, the single pulse with the frequency of more than 20% was fine pulse, string pulse, slippery pulse, and sinking pulse. There were 27 symptoms and signs with a frequency of more than 10%. The characteristic symptoms of acute onset such as lumbar and abdominal pain and nausea, frequent urination, hematuria, and poor urination were relatively common, and other symptoms were chill and fever, defecation, and digestion. ② Among the 14 strong association rules, 5 were yang-deficiency and cold-dampness syndromes, 4 were yin-deficiency and heat syndromes, 1 was kidney-deficiency syndrome, and 3 were renal colic with accompanying symptoms. ③ Sixteen common factors were extracted by factor analysis, and the main elements of the disease location were represented by spleen and kidney. The main elements of disease natures were Yin deficiency, Yang deficiency, dampness, and heat, and often mixed with deficiency-excess in complexity. Six syndromes were obtained by cluster analysis, and the represented syndromes were mainly kidney deficiency and dampness and stasis, Qi stagnation and heat accumulation, Yin deficiency and dampness heat, spleen-kidney Yang deficiency, spleen deficiency and dampness, and dampness-heat accumulation. ConclusionThe syndrome manifestations of urolithiasis are chill and fever, defecation, sweating, and digestive tract symptoms. The deficiency syndromes are mainly Yin deficiency, Yang deficiency, kidney deficiency, and spleen deficiency. The excess syndromes are mainly wet and heat. The deficiency and excess syndromes often exist simultaneously. The spleen deficiency is the important pathogenesis of urolithiasis besides the kidney deficiency.

Degradation of sulfonamides in aquaculture wastewater by laccase-syringaldehyde mediator system: Response surface optimization, degradation kinetics, and degradation pathway.

As a new type of environmental pollutant, environmental antibiotic residues have attracted widespread attention, and the degradation and removal of antibiotics has become an engaging topic for scholars. In this paper, Novozym 51003 industrialized laccase and syringaldehyde were combined to degrade sulfonamides in aquaculture wastewater. Design Expert10 software was used for multiple regression analysis, and a response surface regression model was established to obtain the optimal degradation parameters. In the actual application, the degradation system could maintain a stable performance within 9 h, and timely supplement of the mediator could achieve a better continuous degradation effect. Low concentrations of heavy metals and organic matter would not significantly affect the degradation performance of the laccase-mediator system, making the degradation system suitable for a wide range of water quality. Enzymatic reaction kinetics demonstrated a strong affinity of sulfadiazine to the substrate. Ten degradation products were speculated using high-resolution mass spectrum based on the mass/charge ratios and the publication results. Four types of possible degradation pathways of sulfadiazine were deduced. This work provides a practical method for the degradation and removal of sulfonamide antibiotics in actual sewage.

The effect of Moutan cortex carbonisata nano-components on the blood-cooling and hemostatic / 药学学报

At present, the research of Moutan cortex carbonisata (MCC) mainly focuses on the changes of chemical composition before and after charcoal production, and there is a lack of material basic research directly related to the efficacy at home and abroad. In this study, Moutan cortex, as a precursor, and was calcined to MCC at high temperature. The Moutan cortex carbonisata nano-components (MCC-NCs) were extracted and separated from MCC to explore its cooling-blood and hemostatic effects. In the experiment, the MCC was calcined at a high temperature in a muffle furnace (350 ℃, 1 h), and then MCC-NCs were extracted for MCC, and characterized by transmission electron microscopy and UV-vis absorption spectroscopy, fluorescence spectroscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. In addition, the study evaluated the blood-cooling and hemostatic effects of MCC-NCs. The results showed that MCC-NCs have a size distribution of 0.80-2.8 nm, a lattice spacing of 0.26 nm. MCC-NCs are mainly composed of C, O and N elements and have abundant surface functional groups such as OH, C=O, C-N and C=C. The fluorescence yield of MCC-NCs was 7.18%. The experiments complied with the Animal Ethics Committee of Beijing University of Chinese Medicine. The result indicated that pretreatment MCC-NCs can significantly (P < 0.05) reduce the high, medium, and low viscosity of whole blood and plasma viscosity, and reduce hematocrit, red blood cell distribution width, hemoglobin and red blood cell level. In addition, MCC-NCs significantly reduced the levels of activated partial thromboplastin time, thrombin time and fibrinogen (P < 0.05). The pathological examination results showed that MCC-NCs can significantly reduce lung tissue damage, reduce bleeding and inflammatory cell infiltration. At the same time, it can also significantly reduce the symptoms of gastric mucosal bleeding. In conclusion, the results indicated that MCC-NCs has significantly the effect of blood cooling and hemostasis, and its hemostatic effect is mainly related to the activation of endogenous coagulation pathway or fibrinogen system, which provided a novel strategy for exploring the material basis of traditional Chinese medicine for hemostasis.

Treatment status and meditation of benign gallbladder diseases / 中华消化外科杂志

Benign gallbladder diseases are common diseases in general surgery, including gallstones, polypoid lesions, cholecystitis, etc. In China, the treatment of benign gallbladder diseases is still not standardized, which mainly shows in following aspects: (1)the tendency of cholecystectomy to all gallbladder diseases may result in the incidence of abdominal pain, distension, diarrhea and bile duct injury after surgery; (2)the attitude of "no-surgery" in which the standard cholecystectomy fails to implement in time for the benign gallbladder diseases with potential high-risk factors for gallbladder cancer, as a result, patients develop occurrence of gallbladder cancer. Especially, gallbladder sparing surgery is an unscientific surgery for benign gallbladder diseases, the gallbladder may become a high-risk factor for cancer after the operation. Implementation of standard cholecystectomy in time for benign gallbladder diseases with potential high risk gallbladder cancer can not only significantly reduce the incidence of gallbladder cancer, but also significantly improve the early diagnosis and the prognosis. Based on current literatures, the authors analyze the treatment status of benign gallbladder diseases, and investigate the disputes and problems in surgical indications, operation time and the selection of treatments of benign gallbladder diseases.
