Acute gallstone pancreatitis (AGP) is a kind of acute pancreatitis caused by gallstones. The etiology of AGP is complex, and the anatomic basis and initiating factors have a synergistic effect on its pathogenesis, which needs to be studied jointly. The way of the confluence of pancreaticobiliary ducts, dilated main pancreatic duct, the relatively narrow opening of duodenal papilla and small stones or microlithiasis may be involved in the pathogenesis of AGP, in which small stones are the most important. Etiological diagnosis and clinical treatment of AGP should be carried out simultaneously. The timely selection of treatment methods for different causes can alleviate the patient's condition to the greatest extent and reduce the cost of treatment. At present, it is difficult to unify the prediction indexes of AGP. Meanwhile, the pathogenesis and related prophylaxis and treatment also need to be studied. In this paper, the anatomic basis, initiation factors, pathogenesis and self-defense of AGP were analyzed to provide a new perspective for its treatment.

Objective:To explore the value of amide proton transfer-weighted (APTw) imaging and intravoxel incoherent motion (IVIM) imaging for diagnosing and evaluating the pathological differentiation of cervix squamous cell carcinoma (CSCC).Methods:This study was a diagnostic trial. Totally 56 patients pathologically diagnosed with CSCC at the First Hospital of Lanzhou University from October 2021 to October 2022 were retrospectively collected, as the CSCC group. And 36 female healthy volunteers who underwent physical examinations at the First Hospital of Lanzhou University from October 2021 to October 2023 were recruited as the control group. CSCC patients were divided into well-moderately differentiated ( n=34) and poorly differentiated groups ( n=22). The region of interest was placed in the lesions of CSCC group and normal cervical stroma of control group, and the quantitative parameters for asymmetric magnetization transfer ratio (MTR asym) of APTw imaging and pure diffusion coefficient (D), false diffusion coefficient (D *) and perfusion fraction (f) for IVIM were obtained. The independent sample t test was used to compare the differences in quantitative parameters between the two groups, the logistic regression model was used to establish combined parameters for the quantitative parameters with statistical significance between the two groups. The receiver operator characteristic curve was used to evaluate the diagnostic efficacy of single quantitative parameters and combined parameters to distinguish the CSCC group from the control group, and the well-moderately differentiated group from the poorly differentiated group in CSCC patients. The area under the curve (AUC) was compared using the DeLong test. Results:There were significant differences in MTR asym, D and f between CSCC group and control group ( t=-9.79, 10.09, 11.35, P<0.001). Also, significant differences were found for MTR asym and D between the well-moderately differentiated and poorly differentiated group ( t=4.11, -3.76, P<0.001). There was no significant difference in other quantitative parameters ( P>0.05). When comparing the CSCC group and control group, the AUC (95% CI) of MTR asym, D, f and combined parameter (MTR asym+D+f) were 0.887 (0.804-0.944), 0.940 (0.871-0.979), 0.968 (0.909-0.993), 0.995 (0.950-1.000). The AUC of the combined parameter was higher than those of MTR asym and D, with statistical significance ( Z=3.07, 2.06, P=0.002, 0.040). When comparing the well-moderately differentiated and poorly differentiated group, the AUC (95% CI) of MTR asym, D, and combined parameter (MTR asym+D) were 0.789 (0.660-0.887), 0.775 (0.644-0.876), 0.852 (0.731-0.932). There was no significant difference between each two AUCs ( P>0.05). Conclusion:The quantitative parameters of APTw and IVIM imaging can be used to diagnose and preliminarily evaluate the pathological differentiation of CSCC. Joint parameters can improve the diagnostic efficiency of CSCC.

ObjectiveTo determine the mechanism of Yitangkang in correcting excessive apoptosis of skeletal muscle cells to improve insulin resistance （IR） by inhibiting the advanced glycation end product （AGE）/receptor for the advanced glycation end product （RAGE） signaling pathway. Method① In vitro experiments. Yitangkang-medicated serum was prepared. C2C12 cells were divided into a blank group， a model group， high-， medium-， and low-dose Yitangkang-medicated serum groups （40， 20， and 10 g·kg^-1）， and a RAGE inhibitor group. The IR model was induced by palmitic acid in C2C12 cells except for those in the blank group. After the corresponding intervention methods were conducted，the cell viability and glucose consumption level of each group were determined. In addition，the apoptosis rate was determined using flow cytometry. The mRNA and protein expression levels of the important apoptotic proteins ［B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， p53， cysteinyl aspartate-specific protease-3 （Caspase-3）， and cysteinyl aspartate-specific protease-9 （Caspase-9）］ were determined using Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ② In vivo experiments. Ninety-six eligible Wistar rats were divided into a blank group， a model group， high-，medium-，and low-dose Yitangkang groups （40， 20， and 10 g·kg^-1）， and a western medicine group （pioglitazone hydrochloride，1.35 mg·kg^-1）. The IR model was induced using high-glucose and high-fat feed for diabetes combined with intraperitoneal injection of low-dose streptozotocin （STZ） in animals and verified by the hyperinsulinemic-euglycemic clamp （HEC） test. After the model was determined successfully， the rats in each group were given intragastric administration of drugs as required. Terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） assay was performed to determine the number of positive apoptotic cells in the skeletal muscle tissues of rats in each group，while Real-time polymerase chain reaction（Real-time PCR） and Western blot were performed to determine the mRNA and protein expression levels of the important apoptotic proteins Bcl-2， Bax， p53， Caspase-3， and Caspase-9. Result① In vitro experiments. compared with the blank group， the model groups showed increased apoptosis rate of C2C12 cells and decreased cell viability and glucose consumption （P<0.01）. Compared with the model group， the Yitangkang-medicated serum groups and the RAGE inhibitor group showed decreased apoptosis rate of C2C12 cells and increased cell viability and glucose consumption （P<0.01）. Compared with the blank group， the model group showed decreased expression levels of Bcl-2 mRNA and protein in C2C12 cells and increased mRNA and protein expression levels of Bax， p53， Caspase-3， and Caspase-9 （P<0.01）. Compared with the model group， the Yitangkang-medicated serum groups and the RAGE inhibitor group showed increased expression levels of Bcl-2 mRNA and protein in C2C12 cells （P<0.01） and decreased mRNA and protein expression levels of Bax， p53， Caspase-3， and Caspase-9 （P<0.05， P<0.01）. ② In vivo experiments. The number of positive apoptotic cells in the skeletal muscle tissues of rats in the model group significantly increased as compared with that in the blank group （P<0.01）. The number of positive apoptotic cells in the skeletal muscle tissues of rats in the Yitangkang groups and the western medicine group decreased as compared with that in the model group （P<0.01）. Compared with the blank group， the model group showed decreased expression levels of Bcl-2 mRNA and protein in skeletal muscle tissues of rats and increased mRNA and protein expression levels of Bax， p53， Caspase-3， and Caspase-9 （P<0.01）. Compared with the model group， the Yitangkang groups and the western medicine group showed increased expression levels of Bcl-2 mRNA and protein in skeletal muscle tissues of rats （P<0.01） and decreased mRNA and protein expression levels of Bax， p53， Caspase-3， and Caspase-9 （P<0.05， P<0.01）. The medium-dose Yitangkang showed a similar effect as RAGE inhibitor， and the effect was equivalent to that of pioglitazone hydrochloride. ConclusionYitangkang can inhibit skeletal muscle cell apoptosis by inhibiting the AGE/RAGE signaling pathway.

ObjectiveTo observe the effects of Yuejuwan in the treatment of psychological and heart diseases （PHD） and explore its mechanism. MethodThirty 6-week-old healthy male SPF AopE^-/- mice and 10 homologous C57BL/6J mice were selected for the experiment. The 30 AopE^-/- mice were divided into a model group， low-dose （7.58 g·kg^-1·d^-1） and high-dose （30.32 g·kg^-1·d^-1） Yuejuwan groups， with 10 mice in each group， and 10 C57BL/6J mice were assigned to the blank control group. Intragastrical administration lasted 12 weeks. During feeding， the PHD model was induced by chronic unpredictable mild stress （CUMS） combined with high-fat diet in mice. After intragastric administration， the behavioral results ［open field test （OFT） and sucrose preference test （SPT）］ of mice in each group， the content of aspartic transaminase （AST）， alanine aminotransferase （ALT）， 5-hydroxytryptamine （5-HT）， noradrenaline （NE）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， total cholesterol （TC）， and triglyceride （TG） in serum of mice detected by the automatic biochemical analyzer， the oil red O staining and HE staining of aorta and liver and Masson staining of myocardial tissues were used for model evaluation. Finally， liver TMT-labeled quantitative proteomics was used to explore the mechanism of action. ResultThe model mice showed obvious manifestations of depression， anxiety， loss of interest， and despair， manifest lipid deposition in the aorta and liver by pathological observation， and increased myocardial fibrosis in myocardial tissues. After intragastric administration of Yuejuwan， the above symptoms and indexes of the PHD model mice were improved. Compared with the blank control group， the model group showed decreased standing times， cumulative time in the central area， total moving distance， moving speed， and sucrose preference at week 12 （P<0.01）. Compared with the model group， the Yuejuwan groups showed decreased indexes mentioned above （P<0.01）. After sample collection， AST， ALT， and TG levels in the model group were higher （P<0.01） and the levels of 5-HT， NE， and HDL-C were lower than those in the blank control group （P<0.01）. The results of liver TMT labeled quantitative proteomics suggested that the PHD model mainly caused the changes in protein expression levels such as ApoE， UGT1A5， and FASN in mice，involving acetyl CoA metabolism，response to bacteria，cellular amino acid catabolism， and other processes，which were related to the abnormal metabolic function of the liver. The efficacy of Yuejuwan against PHD was achieved mainly through the regulation of high mobility group nucleosomal-binding domain 2 （HMGN2）， CALD1， and Mup7 protein expression levels and correcting the biological processes and abnormal pathways related to the pathogenesis of PHD，including muscle contraction，tight junction pathway，myocardial contraction pathway，and focal adhesion pathway. ConclusionCUMS combined with high-fat diet is reasonable in the induction of the PHD model in AopE^-/- mice. Yuejuwan can correct the depression and anxiety conditions of PHD model mice，reduce the aortic plaque， and recover the abnormal blood lipid and liver function levels. Furthermore， Yuejuwan can correct abnormal biological processes and pathways of PHD model mice. The differential proteins screened throughout the experiment and the involved physiological and pathological changes are the focus of the next experiment.

【Objective】 To analyze the results, characteristics and clinical value of video urodynamic study (VUD) of lower urinary tract symptoms (LUTS) in young male. 【Methods】 A total of 106 young male LUTS patients (18-45 years old) who received VUD in our hospital during Jan.2016 and Sep.2021 were collected to analyze the clinical and imaging urodynamic characteristics. 【Results】 Of the 106 patients, 55 (52.44%) had neurogenic lower urinary tract dysfunction (NLUTD)with clear neurological etiology, and 51 (48%) had non-neurogenic lower urinary tract dysfunction (NNLUTD). In NLUTD patients, dysuria was the most common symptom (76.74%); lumbosacral lesions were the main cause (76.36%); imaging urodynamics indicated weakening of detrusor muscle in different degrees. In NNLUTD patients,the main symptoms were frequent urination (48.72%) and dysuria (48.72%); about 58.97% of patients had two or more LUTS, and the main diagnosis was detrusor underactivity (DU)(35.90%). 【Conclusion】 NLUTD in young male is characterized by varying degrees of detrusor muscle weakness, detrusor sphincter dyscoordination, and decreased bladder compliance. NNLUTD is mostly caused by detrusor overactivity (DO) and DU.

Objective:To evaluate the mid-term clinical efficacy of drug-coated balloons (DCB)in the treatment of femoro-popliteal artery TASC Ⅱ C/D de novo stenosis and in-stent restenosis.Methods:A total of 126 patients with TASC Ⅱ C/D femoro-popliteal artery stenosis treated with DCB in Renji Hospital and Pudong New Area People's Hospital from December 2016 to August 2020 were retrospectively enrolled, including 74 cases of de novo stenosis (de novo group) and 52 cases of in-stent restenosis (ISR group). The clinical data and lesion characteristics were analyzed; the primary patency rate, primary-assisted patency rate, secondary patency rate, and the freedom from target lesion revascularization (f-TLR)rate were evaluated; the perioperative complications, mortality and amputation rate were compared between two groups. Kaplan-Meier method was used to evaluate the patency rate of target vessel lesions, and Cox regression analysis was used to evaluate the relative risk factors.Results:There were 6 patients died in each group during the followup period. The lesion length of the de novo and ISR groups were (21.25±12.64) cm and (34.71±12.02) cm, respectively( t=33.74, P<0.001). The popliteal artery involvement was 33.8% (25/74) in the de novo group and 15.4% (8/52) in the ISR group (χ 2=5.35, P=0.021). The operational success rate was 100.0% in both groups, and the perioperative complication rate was 6.8% (5/74) in the de novo group and 1.9% (1/52) in ISR group. The median follow-up time was 22 month and 17 months; the mean follow-up time were(19.78 ± 11.02) months and (20.02 ± 11.32) months in the de novo group and ISR group, respectively. The primary patency rates at 6, 12 and 24 months after intervention were 89.1%, 73.4%, 50.8% in the Denovo group, and 87.8%, 68.8%, 42.0% in the ISR group, respectively; the primary assisted patency rate was 90.7%, 78.4%, 62.8% in the de novo group, and 89.3%,77.1%, 62.8% in the ISR group, respectively; the secondary patency rate was 95.1%,95.1%, 88.7% in de novo group, and 94.9%, 88.9%, 84.3% in ISR group, respectively; the f-TLR rate was 97.3%, 88.6%, 79.2% in de novo group, and 90.0%, 77.7%, 74.7% in ISR group, respectively (all P>0.05). Cox regression analysis showed that P2 and P3 segment involvement of the popliteal artery were independent factors affecting the patency rate of target lesion. Conclusions:The mid-term clinical efficacy of DCB in the treatment of TASC Ⅱ C/D femoro-popliteal artery de novo stenosis and in-stent restenosis is satisfactory.

Objective to observe the influence of Candida albicans infection on t cell subsets in mice with spleen deficiency,so as to explore the immune mechanism. Methods totally 150 healthy SPF mice were randomly divided into four groups:control group(N1 group,n = 30);Candida albicans infection group(N2,n = 40),spleen deficiency model group(M1,n = 40),spleen deficiency model combined with Candida albicans in-fection group(M2,n = 40). N2 and M1 mice were infected by Candida albicans at a concentration of 2×108 CFU/mL. ten mice were randomly se-lected from each group at 7,14,and 21 days after infection respectively,and the index was detected. Flow cytometry was used to detect the percent-age of CD4+/CD8+t cells in intestinal mucosa of mice,and the expression level of IL-4 and IFN-γ mRNA was detected by Rt-PCR assay. the levels of IFN-γ and IL-4 were detected by Western blot assay. Results Compared with N1 group,the proportion of CD4+t cells in the lamina of the natu-ral layer of the small intestine was decreased(P < 0.01),the proportion of CD8+t cells was increased(P < 0.01),the ratio of the two was significant-ly decreased(P < 0.01),and the expression levels of IL-4,mRNA IFN-γ and protein in the small intestine tissues were increased in other groups (P < 0.01). In addition,the expression level of IFN-γ was significantly increased in M2 group,while the expression of IL-4 was significantly in-creased in N2 group. Conclusion the susceptibility of Candida albicans infection was increased in spleen deficiency mice,which may be closely related to the regulation of th1/th2 balance.
