OBJECTIVE:To establish a method for the rapid identification of Sanjiu weitai granule and quantitative analysis of moisture. METHODS:Near-infrared (NIR) spectroscopy was adopted. 38 batches of Sanjiu weitai granule were collected,NIR spectrum was determined by integrating sphere diffuse-reflectance. Conformity test model was performed by comparing consistency index(CI)value and CI limit,and quantitative model of moisture was established using partial least squares(PLS)algorithm. RE-SULTS:When CI value was less than 6,the established model can accurately distinguish Sanjiu weitai granule,the model was proven feasible;the correlation coefficient (r2) of quantitative model was 97.44,the root mean square error of cross validation (RMSECV) was 0.453,the root mean square error of prediction (RMSEP) was 0.748. CONCLUSIONS:The method is simple and rapid without destroying,which can be applied to fast screening of Sanjiu weitai granule in site and fast determination of mois-ture content.

OBJECTIVE:To establish a method of quick identification of Fufang yuxingcao tablel(manufactured by A). METH-ODS:NIRDRS was adopted,the near-infrared diffuse reflectance spectrum were recorded by a fiber optic probe,and the conformi-ty test model was established through the consistency index (CI) value and the CI limit comparison method. The spectral range of 9 002-7 497.8 cm-1 ,6 903.8-5 596.4 cm-1 and 5 002.4-4 246.4 cm-1 was selected as the characteristic spectral band ,the spectra were preprocessed by first derivation and vector normalization with 17 smoothing points , and 7.0 was set as the CI value;the characteristic spectrum correlation coefficient model was established through the correlation coefficient method ,the spectral range of 6 200-5 500 cm-1,5 000-4 700 cm-1 was selected as the characteristic spectral band,the spectra were preprocessed by first deri-vation with 17 smoothing points,and 97% was set as the threshold. RESULTS:The above established models can rapidly identify and accurately distinguish Fufang yuxingcao tablet(manufactured by A)from similar products of other manufacturers,the CI value of the validation samples was beyond 7.0,the correlation coefficient(r)were less than 97% compared with the reference sample. CONCLUSIONS:The method is simple and rapid,and can be used for fast screening of Fufang yuxingcao tablet.

This article retrospectively analyzed the clinical data of 8 patients with vesicovaginal fistula after radiotherapy for cervical cancer admitted in our hospital from January 2015 to October 2021. All of them underwent cystostomy under local anesthesia. A single J tube of bilateral ureters was retained under cystoscope, and the single J tube was introduced into the fistula bag through the cystostomy opening. All patients wore diapers for a long time before operation, and used urine pads 0-2 pieces/day after operation. QOL score was 5.3±0.5 points before operation, and 2.5±0.5 points after operation. The patient's body odor basically disappeared. The vesicovaginal fistula can be repaired by surgery, but for patients who cannot be operated or failed repeatedly due to various reasons, a single J tube of bilateral ureters can be drawn out through the cystostomy opening, which can improve the quality of life of patients through minor trauma.

Objective:To analyze the value of serum related cytokines in predicting intestinal mucosal injury in patients with severe acute pancreatitis (SAP) and its correlation with intestinal mucosal injury.Methods:A total of 92 patients with SAP admitted to the First Hospital of Qinhuangdao from January 2020 to December 2021 were included in the study. According to the presence or absence of intestinal mucosal barrier dysfunction, the patients were divided into intestinal mucosal barrier dysfunction group (33 cases) and non-intestinal mucosal barrier dysfunction group (59 cases). Another 100 healthy subjects were selected as the control group. Clinical data of the subjects were collected. Serum levels of procalcitonin (PCT), D-lactic acid (D-L), endotoxin, diamine oxidase (DAO), citrulline and intestinal fatty acid binding protein (I-FABP) of the three groups were compared, and the correlation between the above indexes was analyzed by Pearson correlation analysis. Receiver operating characteristic (ROC) curve was used to analyze the value of each indicator in predicting intestinal mucosal barrier dysfunction in SAP patients.Results:The levels of serum PCT, D-L, endotoxin, DAO and I-FABP in intestinal mucosal barrier dysfunction group, non-intestinal mucosal barrier dysfunction group and control group showed a downward trend, while the level of serum citrulline showed an upward trend, with statistically significant difference (all P<0.05). Pearson correlation analysis showed that serum citrulline was negatively correlated with serum PCT, D-L, and endotoxin levels ( r=-0.740, -0.629, -0.310, all P<0.05); There was a positive correlation between serum DAO and serum PCT, D-L and endotoxin levels ( r=0.482, 0.779, 0.338, all P<0.05); There was a positive correlation between serum I-FABP and serum PCT, D-L and endotoxin levels ( r=0.613, 0.421, 0.341, all P<0.05). The ROC curve results showed that the area under the curve (AUC) of serum PCT, D-L, endotoxin, DAO, citrulline, and I-FABP predicting intestinal mucosal injury in SAP patients were 0.816, 0.789, 0.732, 0.801, 0.812, and 0.857, respectively. The AUC of the combination of the above indicators predicting intestinal mucosal barrier dysfunction in SAP patients was 0.909, significantly higher than that predicted by each index alone (all P<0.05). Conclusions:The occurrence of intestinal mucosal barrier dysfunction in SAP patients may be related to the increase of serum PCT, D-L, endotoxin, DAO, I-FABP levels and the decrease of citrulline levels. It may be considered to predict the risk of intestinal mucosal injury by detecting the levels of various indicators in patients′ serum.

ObjectiveTo evaluate the clinical efficacy of Huayu Tongluo Formula （化瘀通络方， HTF） in patients with mid-stage diabetic kidney disease of blood stasis syndrome and explore its potential mechanisms. MethodsA multi-center， randomized， double-blind， placebo-controlled clinical trial was conducted. Ninety patients of mid-stage diabetic kidney disease of blood stasis syndrome were divided into a control group of 46 cases and a treatment group of 44 cases. Both groups received conventional western medicine treatment， the treatment group additionally taking HTF， while the control group taking a placebo of the formula. The treatment was administered once daily for 24 weeks. The primary outcomes included 24-hour urine total protein （24 h-UTP）， serum albumin （Alb）， glycated hemoglobin （HbA1c）， and serum creatinine （Scr）.The secondary outcomes included changes in levels of endothelin-1 （ET-1）， nitric oxide （NO）， vascular endothelial growth factor （VEGF）， and traditional Chinese medicine （TCM） syndrome scores before and after treatment. Clinical efficacy was evaluated based on TCM syndrome scores and overall disease outcomes. Adverse reactions and endpoint events were recorded. ResultsIn the treatment group after treatment， 24 h-UTP， ET-1， and VEGF levels significantly decreased （P＜0.05）， Alb and NO levels significantly increased （P＜0.05）； while the TCM syndrome scores for edema， lumbar pain， numbness of limbs， dark purple lips， dark purple tongue or purpura， and thin， rough pulse all significantly decreased （P＜0.05）. In the control group， no significant changes were observed in any of the indicators after treatment （P＞0.05）.Compared with the control group， the treatment group showed significant reductions in 24 h-UTP， ET-1， and VEGF levels， and increases in Alb and NO levels （P＜0.05）. The TCM syndrome scores for edema， lumbar pain， dark purple tongue or purpura， and thin， rough pulse were all lower in the treatment group than in the control group （P＜0.05）. The total effective rate of TCM syndrome in the treatment group was 59.09% （26/44）， and the overall clinical effective rate was 45.45% （20/44）. In the control group， these rates were 15.22% （7/46） and 8.7% （4/46）， respectively， with the treatment group showing significantly better outcomes （P＜0.05）. A total of 7 adverse events occurred across both groups， with no significant difference （P＞0.05）. No endpoint events occurred during the study. ConclusionOn the basis of conventional treatment of Western medicine， HTF can further reduce urinary protein levels and improve clinical symptoms in patients with mid-stage diabetic kidney disease of blood stasis syndrome. The mechanism may be related to its effects on endothelial function.
