Currently, the types of kidney stones before surgery are mainly identified by human beings, which directly leads to the problems of low classification accuracy and inconsistent diagnostic results due to the reliance on human knowledge. To address this issue, this paper proposes a framework for identifying types of kidney stones based on the combination of radiomics and deep learning, aiming to achieve automated preoperative classification of kidney stones with high accuracy. Firstly, radiomics methods are employed to extract radiomics features released from the shallow layers of a three-dimensional (3D) convolutional neural network, which are then fused with the deep features of the convolutional neural network. Subsequently, the fused features are subjected to regularization, least absolute shrinkage and selection operator (LASSO) processing. Finally, a light gradient boosting machine (LightGBM) is utilized for the identification of infectious and non-infectious kidney stones. The experimental results indicate that the proposed framework achieves an accuracy rate of 84.5% for preoperative identification of kidney stone types. This framework can effectively distinguish between infectious and non-infectious kidney stones, providing valuable assistance in the formulation of preoperative treatment plans and the rehabilitation of patients after surgery.

By reviewing ancient materia medica, medical books and modern literature, this paper conducted a systematic research on name, origin, scientific name evolution, producing area, quality, harvesting and processing methods of Alpiniae Officinarum Rhizoma. The results showed that Alpiniae Officinarum Rhizoma was first published in Mingyi Bielu, and its correct name was Gaoliangjiang. The mainstream origin of Alpiniae Officinarum Rhizoma used in the past dynasties is Alpinia officinarum, which is used to this day, while it used to be mixed with A. galanga because of the similar name and morphology. Alpiniae Officinarum Rhizoma produced in Danzhou and Leizhou was considered to be better in ancient times, and now it mainly produced in Guangdong, Guangxi and Hainan provinces. In addition, it has been concluded that Alpiniae Officinarum Rhizoma with reddish brown, sturdy and firm character, wrinkled skin, convex flesh, aromatic and spicy taste, and few branches is the best. In ancient times, Alpiniae Officinarum Rhizoma was commonly harvested in February and March, whereas it generally harvested in late summer or early autumn at present, and wild products are usually harvested before the rainy season in May. The main processing methods of Alpiniae Officinarum Rhizoma are cleansing and cutting, and some other methods are stir-frying or mixing with auxiliary materials. Based on the research results, it is suggested that the raw products of A. officinarum rhizomes or its processed products according to prescription requirements should be used in the development of famous classical formulas containing Alpiniae Officinarum Rhizoma.

Objective To investigate the value of interleukin-6 (IL-6) combined with Model for End-stage Liver Disease (MELD) score in predicting the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF). Methods A total of 86 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2018 were enrolled, and according to their survival status after follow-up for 90 days, they were divided into death group with 50 patients and survival group with 36 patients. ELISA was used to measure the serum level of IL-6, and a statistical analysis was performed for general information. The t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A Pearson correlation analysis was performed for IL-6 and other variables; a binary logistic regression analysis was used to investigate the independent risk factors for the prognosis of patients with HBV-ACLF; the receiver operating characteristic (ROC) curve was used to assess the value of IL-6 combined with MELD score in predicting the prognosis of HBV-ACLF. Results There were significant differences between the death group and the survival group in hematocrit ( t =2.413), platelet count ( t =6.584), total bilirubin (TBil) ( t =-8.070), prothrombin time (PT) ( U =77.500), international standardized ratio ( U =102.000), HBV DNA ( t =-2.767), IL-6 ( t =-16.543), and MELD score ( t =-8.192), and the death group had a significantly higher level of IL-6 than the survival group (27.13±12.18 pg/mL vs 9.72±5.56 pg/mL, P < 0.001). The Pearson correlation analysis showed that IL-6 was positively correlated with TBil and PT ( r =0.579 and 0.681, both P < 0.001). The binary logistic regression analysis showed that IL-6 (odds ratio[ OR ]=1.480, 95% confidence interval [ CI ]: 1.196~1.833, P =0.007) and MELD score ( OR =1.128, 95% CI : 1.033~1.231, P < 0.001) were independent risk factors for the death of HBV-ACLF patients within 90 days. IL-6 combined with MELD score had an area under the ROC curve (AUC) of 0.891 (95% CI : 0.778~0.999), with a higher AUC than IL-6 (AUC=0.838, 95% CI : 0.687~0.989) or MELD score (AUC=0.783, 95% CI : 0.634~0.933). IL-6 combined with MELD score had a significantly higher value than IL-6 alone in predicting the prognosis of patients with HBV-ACLF ( Z =-2.257, P =0.024). Conclusion IL-6 combined with MELD score can be used as a good model for predicting the short-term prognosis of patients with HBV-ACLF.

ObjectiveTo investigate the value of interleukin-32 (IL-32) combined with Model for End-Stage Liver Disease (MELD) in predicting the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF). MethodsA total of 92 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2018 were enrolled, and according to the follow-up results at 3 months after diagnosis, the patients were divided into survival group with 40 patients and death group with 52 patients. ELISA was used to measure the serum level of IL-32. Clinical data of the patients were collected, including age, sex, underlying diseases, major complications, white blood cell count (WBC), platelet count (PLT), hematocrit (HCT), total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (Alb), serum creatinine (SCr), prothrombin time (PT), international normalized ratio (INR), and HBV DNA. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; a Pearson correlation analysis was performed for IL-32 and other variables; a binary logistic regression analysis was performed to investigate the independent risk factors for the prognosis of patients with HBV-ACLF. The receiver operating characteristic(ROC) curve(AUC) was used to evaluate the value of IL-32 combined with MELD score in predicting the prognosis of patients with HBV-ACLF. The normal Z test was used for comparison of AUC. ResultsThere were significant differences between the two groups in HCT, PLT, TBil, SCr, PT, INR, HBV DNA, IL-32, and MELD score (all P<0.05). IL-32 was positively correlated with TBil (r=0.952, P<0.001) and MELD score (r=0850, P<0.001). IL-32 (odds ratio [OR]=1.137, 95% confidence interval [CI]: 1040-1243, P=0.005) and MELD score (OR=1.055, 95% CI: 1.001-1.109, P=0.025) were independent risk factors for the death of HBV-ACLF patients. IL-32 combined with MELD score had the highest value in predicting the prognosis of patients with HBV-ACLF (AUC=0.992, 95% CI: 0.981-1000), with a significantly higher AUC than IL-32 (0.992 vs 0.984, Z=2.265, P<0.05) and MELD score (0.992 vs 0877, Z=3182, P<0.05). ConclusionBoth IL-32 and MELD score can predict the prognosis of patients with HBV-ACLF, and the combination of these two indicators has a better predictive value.

ObjectiveTo investigate the role of coagulation function parameters and platelet indices in thrombotic events in patients with hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). MethodsA total of 56 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2019 were enrolled and divided into thrombotic complication (TC) group with 24 patients and non-thrombotic complication (NTC) group with 32 patients. A retrospective analysis was performed for their general clinical data on admission, and the patients were observed in terms of the changes in coagulation function, platelet count (PLT), and the platelet function-related index mean platelet volume (MPV) on days 1-7 after admission. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A repeated measures analysis of variance was used to compare coagulation markers within and between groups at different time points. ResultsOn admission, the TC group had a significantly younger age than the NTC group [31.5 (29.0-34.0) years vs 48.5 (36.0-50.7) years, Z=-2.637, P=0.008]. On the day of admission, there was no significant difference in MPV between the TC group and the NTC group (P >0.05), while on days 2-7 after admission, there was a significant difference in MPV between the two groups (t=-2.696、-2.742、-2.894、-4.174、-3.945、-4.716,all P <0.01). In the TC group, MPV reached the peak value on day 5 of admission, with a mean value of 13.90±1.12 fl, which was higher than the range of normal values. On admission, all patients had a mean prothrombin time (PT) of 28.8±7.2 s, a mean activated partial thromboplastin time (APTT) of 50.5±8.7 s, and a mean international normalized ratio (INR) of 2.6±0.7, which were higher than normal values; all patients had a mean fibrinogen (Fb) level of 1.16±0.3 g/L and a mean PLT of (107.7±26.5)×109/L, which were lower than normal values. There were no significant differences in PT, APTT, Fb, INR, and PLT between the TC group and the NTC group (all P >0.05). ConclusionCoagulation disorder in patients with liver failure is more of a low-equilibrium state, which is complex and heterogeneous and requires individualized treatment. For patients with HBV-ACLF, the development of thrombotic events may be more associated with platelet function than PLT or conventional coagulation markers.

ObjectiveTo investigate the protective effect of fecal microbiota transplantation (FMT) on mice with acute-on-chronic liver failure (ACLF) and its effect on intestinal flora. MethodsA total of 40 mice were randomly divided into control group (CON group), model group (MOD group), FMT group (feces of the mice in the CON group were used as fecal microbiota donor), and FMT model group (ANFMT group, with feces of the mice in the MOD group as fecal microbiota donor), with 10 mice in each group. All mice were observed in terms of body weight, death, liver histopathology, and changes in aspartate aminotransferase (AST), alanine aminotransferase (ALT), and intestinal flora. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the SNK-q test was used for further comparison between two groups. ResultsCompared with the CON group, the MOD group had a significant reduction in body weight and significant increases in AST and ALT (all P<0.05), as well as large patchy necrosis of hepatocytes, significant increases in Verrucomicrobia, Akkermansia, and Erysipelatoclostridium, and significant reductions in Dubosiella and Duncaniella (all P<0.05). Compared with the CON group, the ANFMT group had a significant increase in AST (P<0.05), hepatocyte swelling and mild ballooning degeneration, significant increases in Unclassified and Faecalibaculum, and significant reductions in Patescibacteria, Deferribacteres, Muribaculum, Candidatus_Saccharimonas, Rikenella, Odoribacter, Mucispirillum, and Lachnospiraceae_unclassified (all P<0.05). Compared with the MOD group, the FMT group had significant reductions in AST and ALT (both P<0.05), mild hepatocellular necrosis and marked ballooning degeneration, significant increases in Paramuribaculum and Bilophila, and significant reductions in Firmicutes, Rikenella, and Absiella (all P<0.05). ConclusionIntestinal flora disturbance is observed in ACLF mice, and dysbacteriosis may lead to liver injury. FMT can alleviate liver inflammation in ACLF mice and thus exert a protective effect.

Objective To investigate the serum γ-glutamyl transferase(γ-GT)level and its clinical significances in hepatitis B virus(HBV)-liver failure(LF)patients.Methods γ-GT levels were detected in 89 LF patients,30 cases with cirrhosis and 30 healthy controls.Difference of serum γ-GT between survival group and death group in LF patients and dynamics of γ-GT after hospitalization were studied. Survival rate between γ-GT increase group and decrease group were compared.The associations of γ-GT with model for end stage live disease(MELD)and prealbumin were calculated.Results At baseline,the γ-GT levels in LF,cirrhosis and healthy control groups were(149.61 ± 69.86),(123.96 ± 59.52)and (48.28 ± 10.25)U/L,respectively,the difference among groups was significant(F= 178.150,P<0.05).The survival group in LF patients showed significant increase of γ-GT one week after hospitalization compared with death group([75.27 ± 10.34]vs[29.47 ± 5.05],t=5.40,P<0.05). The γ-GT increase group showed higher survival rate than γ-GT decrease group[76.19%(48/63)vs 23.08%[6/26],χ2=21.76,P<0.05].Serum γ-GT level in LF patients was positively correlated with both MELD score and prealbumin(r=0.709 and -0.627,respectively,both P<0.05).Conclusions The rise of γ-GT may indicate a better prognosis in LF patients.Serum γ-GT positively correlates with prealbumin and both could reflect the regeneration of hepatocytes.
