Xiaoji Yinzi is one of the classic prescriptions for treating urinary diseases， originated from the Yan's Prescriptions to Aid the Living （Yan Shi Ji Sheng Fang） written by YAN Yonghe in the Song dynasty. Xiaoji Yinzi is composed of Rehmanniae Radix， Cirsii Herba， Talcum， Akebiae Caulis， Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， Angelicae Sinensis Radix， Gardeniae Fructus， and Glycyrrhizae Radix et Rhizoma and has the effects of cooling blood and stopping bleeding， draining water and relieving stranguria. The medical experts of later generations have inherited the original prescription recorded in the Yan's Prescriptions to Aid the Living， while dispute has emerged during the inheritance of this prescription. In this study， the method of bibliometrics was employed to review and analyze the ancient documents and modern clinical studies involving Xiaoji Yinzi. The results showed that Xiaoji Yinzi has two dosage forms： powder and decoction. According to the measurement system in the Song Dynasty， the modern doses of hers in Xiaoji Yinzi were transformed. In the prepration of Xiaoji Yinzi powder， 149.2 g of Rehmanniae Radix and 20.65 g each of Cirsii Herba， Talcum， Akebiae Caulis， stir-fried Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， wine-processed Angelicae Sinensis Radix， stir-fried Gardeniae Fructus， and stir-fried Glycyrrhizae Radix et Rhizoma are grounded into fine powder with the particle size of 4-10 meshes and a decocted with 450 mL water to reach a volume of 240 mL. After removal of the residue， the decoction was taken warm before meals， 3 times a day （i.e.， 7.77 g Rehmanniae Radix and 0.97 g each of the other herbs each time）. In the preparation of Xiaoji Yinzi decoction， 20.65 g each of the above 10 herbs are used， with stir-fried Typhae Pollen， wine-processed Angelica Sinensis Radix， stir-fired Gardeniae Fructus， stir-fired Glycyrrhizae Radix et Rhizoma， and raw materials of other herbs. Xiaoji Yinzi is specialized in treating hematuresis and blood stranguria due to heat accumulation in lower energizer， which causes injury of the blood collaterals of gallbladder and dysfunction of Qi transformation. In modern clinical practice， Xiaoji Yinzi is specifically used for treating urinary diseases and can be expanded to treat diseases of the cardiovascular system and other systems according to pathogenesis. The comprehensive research on the key information could provide a scientific reference for the future development of Xiaoji Yinzi.

OBJECTIVES: To explore the risk factors for malnutrition in patients with ulcerative colitis complicated with pyoderma gangrenosum and establish a nutritional risk prediction model for these patients. METHODS: A total of 277 patients with ulcerative colitis complicated with pyoderma gangrenosum treated from 2019 to 2024 were divided into malnutrition group (n=185) and normal nutrition group (n=92) according to whether malnutrition occurred. The data of 25 potential related factors pertaining to general demography, living and eating habits, and disease-related data were compared between the two groups. Lasso regression was used to screen the risk factors, and a nomogram model was established based on the screened factors and its prediction performance was assessed. RESULTS: The patients in the malnutrition group and normal nutrition group showed significant differences in 21 factors including gender, age, education level, BMI, place of residence, course of disease, and SAS language score (P<0.05). Lasso regression analysis identified 6 factors associated with malnutrition in these patients, namely the duration of ulcerative colitis, activity of ulcerative colitis, duration of pyoderma gangrenosum, number of chronic diseases, SAS score, and sleep quality. The nomogram prediction model established based on these 6 factors had an AUC of 0.992 (95% CI: 0.984-1.000) for predicting malnutrition in these patients, and its application in 14 clinical cases achieved an accuracy rate of 100%. CONCLUSIONS The duration of ulcerative colitis, activity of colitis, duration of pyoderma gangrenosum, number of chronic diseases, anxiety, and sleep quality are closely related with malnutrition in patients with ulcerative colitis complicated by pyoderma gangrenosum, and the nomogram prediction model based on these factors can provide assistance for predicting malnutrition in these patients.

MethodA total of 150 senile patients with slow transit constipation were randomized into control group （75 cases） and observation group （75 cases） with the random number table method. The observation group was given modified Jichuanjian （oral， 1 dose/day， 4 weeks）， and the control group was treated with Biantong Capsules （oral， 3 capsules/time， twice/day， 4 weeks）. Data before and after treatment were recorded， including the score of major constipation symptoms， score of Patient Assessment of Constipation Quality of Life （PAC-QOL）， TCM syndrome score， spontaneous complete bowel movements （SCBM）， colonic transit test， serum 5-hydroxytryptamine （5-HT）， 5-HT 4 receptor （5-HT₄R）， somatostatin （SS）， and vasoactive intestinal peptide （VIP）， and recurrence. ResultThe total effective rate of the observation group was 93.06% （67/72）， as compared with the 74.65% （53/71） in the control group （χ²=8.974 6， P<0.01）. After treatment， the scores of major constipation symptoms， scores of four dimensions of PAC-QOL， total score of PAC-QOL， and TCM syndrome score were lower than those before treatment in the two groups （P<0.01）， and lower in the observation group than in the control group （P<0.01）. The SCBM in the observation group were more than those in the control group at the 2^nd， 3^rd， 4^th weeks after treatment （P<0.01）. The proportions of residual markers at 24， 48， 72 h after treatment were smaller than those before treatment in the two groups （P<0.01）， and smaller in the observation group than in the control group （P<0.01）. After treatment， the levels of serum 5-HT and 5-HT₄R were higher （P<0.01） and the levels of serum SS and VIP were lower （P<0.01） than those before treatment in the two groups. In addition， the levels of serum 5-HT and 5-HT₄R in the observation group were higher （P<0.01） and the levels of serum SS and VIP were lower （P<0.01） in the observation group than in the control group. The recurrence in the observation group was 29.85% （20/67） in comparison with the 58.49% （31/53） in the control group （χ²=9.932 4， P<0.01）. ConclusionModified Jichuanjian is effective for senile patients with slow transit constipation of spleen-kidney yang deficiency syndrome， which can alleviate clinical symptoms， improve quality of life， regulate the level of serum brain-gut peptide， improve the colonic transit function， increase SCBM， and reduce the recurrence.

Objective To develop a convolution neural network (CNN) model to classify multi?sequence MR images of the prostate. Methods ResNet18 convolution neural network (CNN) model was developed to classify multi?sequence MR images of the prostate. A deep residual network was used to improve training accuracy and test accuracy. The dataset used in this experiment included 19 146 7?sequence prostate MR images (transverse T1WI, transverse T2WI, coronal T2WI, sagittal T2WI, transverse DWI, transverse ADC, transverse PWI), from which a total of 2 800 7?sequence MR images was selected as a training set. Three hundred and eighty eight 7?sequence MR images were selected as test sets. Accuracy was used to evaluate the effectiveness of ResNet18 CNN model. Results The classification accuracy of the model for transverse DWI, sagittal T2WI, transverse ADC, transverse T1WI, and transverse T2WI was as high as 100.0% (44/44,52/52), and the accuracy for transverse PWI was also as high as 96.7% (116/120). The accuracy for coronal T2WI was 77.5% (31/40). 0.8% (1/120) of transverse PWI was incorrectly assigned to transverse T2WI, and 2.5% (3/120) incorrectly assigned to sagittal T2WI. 15.0% (6/40) of coronal T2WI was incorrectly assigned to transverse T2WI, and 7.5% (3/40) to sagittal T2WI. Conclusion The experimental results show the effectiveness of our deep learning method regarding accuracy in the prostate multi?sequence MR images detection.

OBJECTIVE: To discuss the diagnostic value of pneumoperitoneum helico-CT imaging (PHCT) in cases of post-operative peritoneal adhesion (POPA). METHODS: We retrospectively analyzed the PHCT scan pictures from 32 consecutive patients with chronic abdominal pain or recurrent mechanical intestinal obstruction after abdominal operation. RESULTS: In a normal peritoneal cavity without adhesion, an air distended dome-like space would be demonstrated with the abdominal organs arranged smoothly on the bottom of the shadow. Any additional shadow appearing in the dome-space would suggest adhesion or something abnormal. Positive findings of peritoneal adhesion were found in 30 of the 32 patients (93.75%). A spot adhesion at the abdominal wall making a kinking of intestine usually showed a cuneiform bulging shadow pointed to the roof of the dome-space. Organs involved in the adhesion may be single or multiple, including the liver, stomach, small intestine, colon, uterus, and omentum. In all the 32 patients, PHCT diagnosis was confirmed by the subsequent laparoscopy treatment. CONCLUSION PHCT imaging is valuable in making a definite diagnosis of POPA, particularly before a blind laparoscopic exploration. It is a replacement for laparoscopy but much simpler, and may offer a valuable help in dealing with the difficult cases of suspected POPA. A negative imaging is sometimes very important to an undetermined postoperative chronic abdominal pain.
