ObjectiveTo explore the scientific connotation of fried charcoal survivability of Lonicerae Japonicae Flos(LJF) by analyzing the correlation between the color change and the intrinsic components during the processing of LJF Carbonisata(LJFC), and taking pH, charcoal adsorption and microscopic characteristics as indexes. MethodLJFC samples with different degrees of processing were prepared according to the stir-frying time of 0.0, 1.5, 3.0, 4.5, 6.0, 7.5, 9.0, 10.5 min(numbered S1-S8), and the contents of gallic acid, chlorogenic acid, cryptochlorogenic acid, rutin, luteoloside, isochlorogenic acid A and isochlorogenic acid C were determined by high performance liquid chromatography(HPLC), and the L*(brightness), a*(red-greenness) and b*(yellow-blueness) of LJFC samples with different degrees of processing were determined by spectrophotometer, and the correlation analysis and principal component analysis(PCA) between the contents of seven representative components and the color of the samples were carried out by SPSS 26. 0 and SIMCA-P 14.1. Then pH, adsorption force and characteristic structure of different samples of LJFC were detected and the processing pattern of LJFC was analyzed. ResultThe results of quantitative analysis revealed that the contents of luteoloside, rutin, chlorogenic acid and isochlorogenic acid A gradually decreased, and the contents of cryptochlorogenic acid, isochlorogenic acid C and gallic acid firstly increased and then decreased. The L* and b* of the sample powders decreased, and a* showed a trend of increasing and then decreasing. The L* and b* were positively correlated with the contents of chlorogenic acid, rutin, luteoloside, isochlorogenic acid A, b* was positively correlated with the content of gallic acid, and a* was positively correlated with the contents of cryptochlorogenic acid and isochlorogenic acid C. PCA revealed that samples could be clearly divided into 3 groups, S1-S2 as one group, S3-S5 as one group, and S6-S8 as one group, with S3 having the highest score. The results of regression analysis showed that only isochlorogenic acid C could be used to predict the contents of components by colorimetric values combined with regression equations. Physicochemical analysis showed that pH of LJFC increased with the increase of degree of charcoal stir-frying, while adsorption force showed a tendency of increasing and then decreasing, with the highest adsorption force in the S5 sample, and the non-glandular hairs, calcium oxalate clusters and pollen grains had a varying degree of decreasing with the deepening of processing degree, and the microstructures of S6-S8 samples were obviously charred with pollen grains almost invisible. ConclusionThe changes in chemical composition and color characteristics of LJFC during the processing have certain correlations, combined with the changes in physicochemical properties, S5 sample is found to be the optimal processed products, which can provide a reference for the processing standardization and quality evaluation of LJFC, and enrich the scientific connotation of fried charcoal survivability of LJF.

Aim To investigate the therapeutic effect of the MW-9 on ulcerative colitis(UC)and reveal the underlying mechanism, so as to provide a scientific guidance for the MW-9 treatment of UC. Methods The model of lipopolysaccharide(LPS)-stimulated RAW264.7 macrophage cells was established. The effect of MW-9 on RAW264.7 cells viability was detected by MTT assay. The levels of nitric oxide(NO)in RAW264.7 macrophages were measured by Griess assay. Cell supernatants and serum levels of inflammatory cytokines containing IL-6, TNF-α and IL-1β were determined by ELISA kits. Dextran sulfate sodium(DSS)-induced UC model in mice was established and body weight of mice in each group was measured. The histopathological damage degree of colonic tissue was assessed by HE staining. The protein expression of p-p38, p-ERK1/2 and p-JNK was detected by Western blot. Results MW-9 intervention significantly inhibited NO release in RAW264.7 macrophages with IC50 of 20.47 mg·L-1 and decreased the overproduction of inflammatory factors IL-6, IL-1β and TNF-α(P<0.05). MW-9 had no cytotoxicity at the concentrations below 6 mg·L-1. After MW-9 treatment, mouse body weight was gradually reduced, and the serum IL-6, IL-1β and TNF-α levels were significantly down-regulated. Compared with the model group, MW-9 significantly decreased the expression of p-p38 and p-ERK1/2 protein. Conclusions MW-9 has significant anti-inflammatory activities both in vitro and in vivo, and its underlying mechanism for the treatment of UC may be associated with the inhibition of MAPK signaling pathway.

Objective:To compare the feasibility and safety of a new portable endoscopic system and the conventional endoscopic system for the detection and emergency treatment of abdominal trauma in animal models.Methods:Three healthy Bama pigs, which were fasted and water deprivation for 8 h before surgery and then underwent induction anesthesia. A layer-by-layer incision was made into the abdominal cavity of Bama pigs. An artificial pneumoperitoneum was established using a laparoscopic pneumoperitoneum machine. A bullet model was inserted into the abdominal cavity to build the bullet wound model. After the bullet model was removed, a shrapnel model was inserted into the mid-abdomen to build the shrapnel wound model. The two types of endoscopic system were used to detect, remove bullet model or shrapnel model of the three Bama pigs respectively. The procedure order of the two systems was assigned according to the random number table method. The surgical success, operation time, endoscopy pipeline patency, endoscopic operation satisfaction, adverse events and equipment defects were recorded.Results:Three surgeries were performed using the new portable endoscopic system and three other surgeries using the conventional endoscopic system, all of which were successful. The time of the new portable endoscopic system to find and remove the bullet model, and the shrapnel model were 232.33±11.68 s, 300.33±57.70 s, 170.00±44.44 s and 52.67±2.52 s, respectively. The corresponding time of the conventional endoscopic system were 232.67±21.20 s ( t=-0.054, P=0.962), 256.67±67.00 s ( t=0.880, P=0.472), 176.00±52.42 s ( t=-0.111, P=0.922), 58.67±14.84 s ( t=-0.832, P=0.493), respectively. There was no significant difference between the two systems ( P>0.05). The endoscopy tubes of the two endoscopic systems were both smooth. The operator was satisfied with the endoscopic procedures of both endoscopic systems, and no adverse event or device defect occurred. Conclusion:The portable endoscopic system proves to be safe and feasible for the diagnosis and treatment of abdominal trauma in animal models.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for circular superficial esophageal cancer.Methods:A retrospective analysis was conducted on 74 consecutive cases of circular superficial esophageal squamous cell carcinoma treated with ESD at Nanjing Drum Tower Hospital from January 2015 to December 2019. The success rate of ESD, curative resection rate, incidence of complications, and additional treatment were mainly observed.Results:One case was transferred to surgery, and the remaining 73 cases successfully completed ESD treatment. The success rate of ESD was 98.6%. Postoperative pathology of ESD revealed that 39 cases achieved curative resection, with a curative resection rate of 53.4% (39/73). Intraoperative muscle layer injury occurred in 15 cases (20.5%), and intraoperative perforation occurred in 1 case (1.4%). Two cases (2.7%) experienced delayed bleeding, and one case (1.4%) experienced delayed perforation. Eleven cases were lost to follow-up, and the remaining 62 cases received follow-up for 36.4±19.0 months. Among the follow-up cases, 12 underwent additional surgery and 5 cases additional chemotherapy and radiotherapy. Among the 57 patients with follow-up data who did not underwent surgery, 49 developed esophageal stenosis after ESD, with an incidence rate of 86.0%.Conclusion:ESD for circular superficial esophageal cancer is generally safe, but it is prone to muscle layer injury during the operation, with a low curative resection rate, a high incidence of postoperative esophageal stenosis, and a high proportion of additional surgical procedures.

ObjectiveTo investigate the therapeutic effects and difference in the effects of Arisaematis Rhizoma (AR) before and after processing (i.e., Arisaematis Rhizoma Preparatum, ARP) with Zingiberis Rhizoma Recens-Alumen on allergic asthma in rats and to provide a basis for the theory of processing improving the efficacy. MethodA rat model of allergic asthma was established in 70 SD rats by intraperitoneal injection of ovalbumin (OVA)-aluminum hydroxide. The rats were administrated with the aqueous extracts of AR (1.2, 0.3 g∙kg-1) and ARP (1.2, 0.3 g∙kg-1) aqueous extracts by gavage, and montelukast sodium (0.001 g∙kg-1) was used as the positive drug. The T helper cell type 1/type 2 (Th1/Th2) ratio in the serum and bronchoalveolar lavage fluid (BALF) and percentages of inflammatory cells in BALF were determined. Polymerase chain reaction (PCR) was employed to determine the mRNA level of mucin 5AC (MUC5AC) in the lung tissue. The pathological changes in the lung tissue were observed by hematoxylin-eosin (HE) staining and PAS staining. Immunohistochemical assay was employed to measure the expression of c-Jun amino-terminal kinase (JNK), extracellular signal regulated protein kinase (ERK), and p38 mitogen-activated protein kinase (p38 MAPK) in rat lung tissue. Western blot was employed to determine the protein levels of ERK, p-ERK, JNK, p-JNK, p38, p-p38 in the lung tissue. The effects of AR and ARP were compared based on overall desirability. ResultCompared with the blank group, the levels of interleukin-12 (IL-12) and γ interferon (IFN-γ) in serum and BALF of rats in the model group were significantly lower (P<0.05, P<0.01), and the levels of interleukin-4 (IL-4), interleukin-5 (IL-5) and interleukin-13 (IL-13) were significantly higher (P<0.05, P<0.01). Compared with the model group, the serum and BALF contents of IL-12 and IFN-γ in rats in the montelukast sodium group, high-dose AR group and high-dose ARP group were significantly higher (P<0.05, P<0.01), and the contents of IL-4, IL-5 and IL-13 were significantly lower (P<0.05, P<0.01), and the serum contents of IFN-γ in rats in the low-dose AR group and low-dose ARP group were in BALF was significantly higher (P<0.05) and IL-4 and IL-13 were significantly lower (P<0.05, P<0.01), the percentages of macrophages, lymphocytes, neutrophils, and eosinophils were reduced in BALF, and the expression of JNK/ERK/p38 MAPK signaling pathway and MUC5AC protein was inhibited in lung tissues. Overall assessment of the normalized analysis revealed that the ARP group was slightly more potent than the AR group after administration of the same dose. ConclusionAR and ARP can effectively treat allergic asthma by inhibiting JNK/ERK/p38 MAPK signaling pathway, and the effect is better after concoction, which can provide data support for its "concoction efficiency".
