ABSTRACT
ObjectiveTo investigate the effect of Fuzheng Huayu prescription on hepatocyte extinction and regeneration in fibrotic liver and its mechanism of action in promoting hepatocyte regeneration. MethodsMice were given intraperitoneal injection of CCl4 for 6 weeks to establish a model of liver cirrhosis， and there were 10 mice in the model group， 10 in the sorafenib group， 10 in the Fuzheng Huayu prescription group， and 9 in the normal control group. Since week 4 of modeling， the mice in the Fuzheng Huayu prescription group and the sorafenib group were given the corresponding drug by gavage at a dose of 4.8 g/kg and 4 mg/kg， respectively， for three consecutive weeks， and those in the normal group and the model group were given an equal volume of sodium carboxymethyl cellulose. Serum liver function parameters were measured； the METAVIR scoring system was used to evaluate liver inflammation and fibrosis stage； Sirius Red staining and hydroxyproline （Hyp） content in liver tissue were used to evaluate collagen deposition； immunohistochemistry was used to measure the protein expression levels of type IV collagen， CD31， CD32b， Ki67， CyclinD1， glutamine synthetase， Wnt2， and HGF， and Western blot was used to measure the expression levels of Wnt2， LRP6， β-catenin， p-β-catenin， and CyclinD1 in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the model group， the Fuzheng Huayu prescription group and the sorafenib group showed the following changes： significant reductions in the serum levels of alanine aminotransferase and aspartate aminotransferase and the content of Hyp in liver tissue （all P<0.01）； a significant reduction in METAVIR score； significant reductions in the expression levels of type Ⅳ collagen and CD31 （all P<0.05） and a significant increase in the expression level of CD32b （P<0.01）； significant reductions in the number of parenchymal extinction lesions and significant increases in the expression levels of Ki67 and CyclinD1 in liver tissue （all P<0.01）； significant increases in the protein expression levels of Wnt2， LRP6， β-catenin， and CyclinD1 and a significant reduction in the protein expression level of p-β-catenin （all P<0.05）； significant increases in the number of cells stained positive for both CD32b and Wnt2. ConclusionFuzheng Huayu prescription can inhibit hepatic sinusoidal capillarization， improve the Wnt2 exocrine function of liver sinusoidal endothelial cells， activate the Wnt/β-catenin signaling pathway associated with hepatocyte regeneration， and finally reverse liver cirrhosis.

ABSTRACT
Objective:To investigate the quality of life in children with McCune-Albright syndrome (MAS) and its influencing factors, so as to provide scientific basis for improving their quality of life.Methods:The clinical data of 31 children with MAS diagnosed (MAS group) and followed up in Henan Children′s Hospital from June 2015 to December 2021 were retrospectively analyzed.During the same period, 37 healthy age and sex-matched children at a ratio of 1∶1 were recruited as healthy control group.The children′s Quality of Life Universal Core Scale (PedsQL?4.0) was used for the investigation and comparative analysis.Statistical analysis was performed using the independent sample t test, Chi- square test and multiple regression analysis. Results:Compared with the healthy control group, the physiological function ( t=2.092, P<0.05), emotional function ( t=2.373, P<0.05) and total score ( t=2.360, P<0.05) of MAS group significantly decreased.Multiple regression analysis showed that physiological function was negatively correlated with the annual number of vaginal bleeding ( t=-2.367, P<0.05) and the age of first fracture ( t=-2.606, P<0.05). Social function was negatively correlated with the number of fractures ( t=-2.481, P<0.05). Conclusions:The overall quality of life of MAS children is low, especially the quality of physiological function and emotional function.The annual number of vaginal bleedings, the age of the first fracture and the number of fractures are influencing factors for the reduction of the quality of life of children with MAS.
ABSTRACT
Objective To investigate the therapeutic effect of traditional Chinese medicine (TCM) on portal vein thrombosis (PVT) in patients with liver cirrhosis and its medication characteristics. Methods A retrospective analysis was performed for 89 patients with liver cirrhosis and PVT who were hospitalized and treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and according to whether TCM treatment was applied in combination, they were divided into TCM group with 59 patients and control group with 30 patients. Related data were collected for the two groups, including demographic data, laboratory examination, radiological examination, gastroscopy, history of surgery, portal hypertension-related complications, medication, and follow-up data. The independent samples 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 or the Fisher's exact test was used for comparison of categorical data between two groups. An ordinal polytomous Logistic regression analysis was used for multivariate analysis. TCM Inheritance Computing Platform (V3.0) was used to perform a drug effect cluster analysis of TCM prescriptions. Results The multivariate logistic regression analysis showed that esophageal and gastric varices (odds ratio [ OR ]=3.144, 95% confidence interval [ CI ]: 1.221-8.094), PVT involving the portal vein (PV) and the superior mesenteric vein (SMV) ( OR =51.667, 95% CI : 3.536-754.859), PVT involving PV+spleen vein (SV)+SMV ( OR =13.271, 95% CI : 2.290-76.928), cavernous transformation of the portal vein ( OR =11.896, 95% CI : 1.172-120.696), and TCM intervention ( OR =0.348, 95% CI : 0.129-0.938) were influencing factors for the outcome of PVT in liver cirrhosis. Follow-up results showed that compared with the control group, the TCM group had a significantly lower progression rate (16.95% vs 56.67%, P < 0.001) and a significantly lower incidence rate of variceal rupture and bleeding (8.47% vs 33.33%, P < 0.001). Effective TCM drugs with a relatively high frequency of use included deficiency-tonifying drugs (359 times, 34.6%), blood-activating and stasis-resolving drugs (202 times, 19.5%), and diuresis-inducing and dampness-draining drugs (180 times, 17.3%); the TCM drugs with a relatively high frequency of use included Astragalus membranaceus (57 times, 8.7%), Angelica sinensis (50 times, 7.6%), and leech (48 times, 7.3%); TCM drug combinations with a relatively high frequency of use included Astragalus membranaceus+Angelica sinensis, Astragalus membranaceus+leech, Angelica sinensis+leech, and Astragalus membranaceus+Angelica sinensis+leech. Conclusion Qi-tonifying, blood-activating, and stasis-breaking drugs, such as Astragalus membranaceus, Angelica sinensis, and leech, can promote the stabilization or recanalization of PVT in liver cirrhosis and reduce the incidence rate of bleeding events due to portal hypertension.
ABSTRACT
Autophagy plays a crucial role in maintaining normal structure and vascular function in vivo. When stress-relevant stimuli are involved, the increases of autophagy can protect vascular smooth muscle cells, promote cell survival, and phenotype transformation, as well as reduce calcification. On the contrary, the decrease of autophagy can accelerate cell senescence, resulting in structural changes and dysfunction of vasomotor and vasodilation. However, excessive activation of autophagy can induce the damage of the healthy protein and essential organelles, and even lead to autophagic cell death, accelerating the progression of vascular disease. Thus, the precise targeting of autophagy opens a novel way for treatment of vascular diseases.

ABSTRACT
Objective: To explore the impact of ticagrelor on platelet aggregation in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention(PCI). Methods: A total of 98 ACS patients received PCI in our hospital from 2015-01 to 2015-12 were enrolled. The patients were randomly divided into 2 groups: Clopidogrel group, the patients received oral clopidogrel 300mg at first time and then maintained by 75mg/qd, n=48 and Ticagrelor group, the patients received oral ticagrelor 180mg at first time and then maintained by 90mg/bid, n=50. All patients were treated for 12 months.The level of vasodilator stimulated phosphoprotein (VASP) phosphorylation and platelet reactivity index (PRI) at pre-medication and 24h, 7 days and 1 month after PCI were detected; major adverse cardiovascular events (MACE) and bleeding events were recorded within 1 month after PCI, the incidence of platelet aggregation, MACE and bleeding events were compared between 2 groups.Results: The baseline information and PCI condition were similar between 2 groups, P>0.05. The overall average PRI was different between 2 groups, P0.05. Conclusion: Ticagrelor was superior toclopidogrel for anti-platelet aggregation in ACS patients after PCI, it didn't increase bleeding events.
ABSTRACT
Objective To investigate the surgical methods and experience of laparoscopic radical cystectomy and orthotopic ileal neobladder for invasive bladder cancer. Methods The clinical data of 14 patients with invasive bladder cancer underwent laparoscopic radical cystectomy and orthotopic ileal neobladder were collected retrospectively during March 2011 and October 2014. Results The 13 patients with invasive bladder cancer were successfully completed laparoscopic radical cystectomy and orthotopic ileal neobladder. 1 case was treated with laparotomy because of unsatisfactory surgery ifeld caused by excessive tumor bleeding. Twelve cases of the urethra-neobaldder anastomosis were completed through the abdominal incision, while for the other 2 cases, the anastomosis was done under the laparoscope, 2 cases were performed neovesicourethral anastomosis using single-needle running sutures through laparoscopy. The median operative time was 444 minutes, the mean intraoperative blood loss was 490 ml. Postoperative pathologic results conifrmed that 12 cases were bladder transitional cell carcinoma (1 case with partial squamous cell carcinoma) and 2 cases with bladder adenocarcinoma. No severe complication occurred except for 2 cases of urinary leakage and 1 case of urinary incontinence. Patients were followed up for 6-56 months,within which 3 patients were died of distant metastasis, 1 case was detected with intracranial metastasis, 1 case was found with urethra-vesical anastomotic stenosis while cured after urethrotomy. Ten cases were well recovered and the mean volume of the neobladder was 300 ml. Conclusions Laparoscopic radical cystectomy and orthotopic ileal neobladder have the advantage of better therapeutic effects, safety, minimal invasion and rapid recovery, which are the preferred therapeutic methods for invasive bladder cancer.

ABSTRACT
Objective To evaluate the protective effect of polysaccharide nucleic acid fraction of bacillus Calmette-Guerin (BCG-PSN) against atopic dermatitis (AD) in Nc/Nga mice,and to explore its possible mechanism.Methods Sixteen Nc/Nga mice were classified into normal control group (n =4),low-concentration BCG-PSN group (n=5) and high-concentration BCG-PSN group (n =7) to be subcutaneously injected with sodium chloride physiological solution,BCG-PSN of 0.1 mg/kg and 0.5 mg/kg respectively,at 1,8,15 and 22 days of age.Dinitrochlorobenzene (DNCB) was repeatedly and topically applied to these Nc/Nga mice to induce AD-like lesions at 49 days of age.The preventive effect of BCG-PSN against AD was evaluated by dermatitis scores,scratching frequency,histopathological manifestations and immunological parameters (including IgE,i nterleukin (IL)-4 and-12,and interferon (IFN)-γ).Results Repeated injection of BCG-PSN within 4 weeks after birth significantly decreased the severity of DNCB-induced AD-like lesions,dermatitis scores and scratching behavior in Nc/Nga mice.There was no statistical difference in scratching frequency between the high-and low-concentration BCG-PSN groups.BCG-PSN treatment reduced the plasma level of IgE in Nc/Nga mice in a dose-dependent manner.BCG-PSN at 0.5 mg/kg increased the number of cells secreting IFN-γ in skin lesions of mice.Both doses of BCG-PSN down-regulated IL-4 level,but up-regulated IL-12 level in the culture supernatant of spleen mononuclear cells from mice.Conclusion Early injection of BCG-PSN could protect Nc/Nga mice against dermatitis by promoting the proliferation of IFN-γ-secreting cells,increasing the synthesis of IL-12,and reducing the levels of IL-4 and IgE.
ABSTRACT
ObjectiveTo investigate the expression of miR-21 in diffuse large B cell lymphoma (DLBCL)and normal lymph tissues and its potential relevance with clinicopathological characteristics.MethodsThe expression levels of miR-21 in 50 primary DLBCL and 12 normal lymph node tissue specimens were examined by TaqMan real-time polymerase chain reaction.The expression of bcl-2 and p53 was detected by immunohistochemistry staining. ResultsThe expression of miR-21 was significantly higher in tumor tissues than that in normal tissues, in GCB subtypes higher than in non-GCB subtypes. And it was negatively correlated with bcl-2(P=0.020),while positively correlated with p53(P=0.022). Up-regulated miR-21 expression was low in three years of survival rate. ConclusionMiR-21 may indicate a more aggressive phenotype and serve as a molecular prognostic marker in DLBCL. High-expression of miR-21 is a key feature that is correlated with cell proliferation in DLBCL.miR-21 may have some guiding significance in prognosis.bcl-2,p53 is possibly one of the targets of miR-21 in DLBCL.
ABSTRACT
Objective To determine the effect of bacille Calmette-Guerin-polysaccharide nucleic acid (BCG/PSN)on 2,4-dinitrochlorobenzene(DNCB)-induced atopic dermatitis-like skin lesions in Nc/Nga mice.Methods Fifteen mice were randomly and equally classified into 3 groups,i.e.,control group receiving topical acetone on foot pad and abdomen and intraperitoneal injection of physiological saline,model group receiving topical 5% DNCB solution and intraperitoneal injection of physiological saline,treatment group receiving 5% DNCB solution and intraperitoneal iniection of BCG/PSN,and all drugs were used every other day for 7 weeks.Further more,0.1% DNCB was topically applied on the ear and neck of Nc/Nga mice once a week from week 2 to week 7.The effects of BCG/PSN were evaluated by ear thickness,skin histopathology and immunological parameters.Results Repeated application of DNCB caused the development of eczematous dermatitis in mice.Mice in model group chnieally manifested skin dryness,erythema,edema and erosion with histopathological changes including dermal and epidermal thickening,hyperkeratosis,and inflammatory infiltration.The serum levels of IL-4 and IrE in model group were significantly higher than those in control group[(174.72±12.64)μg/L vs (17.32±3.56)μg/L,(91.49±6.32)ng/L vs (83.95±6.63)ng/L,both P<0.05].Increased serum IL-12 and IFN-γ and decreased serum IgE were observed in treatment group compared with the model group[(122.10±4.64)ng/L vs (20.14±6.15)ng/L(73.89±2.39)ng/L vs (51.53±3.45)ng/L, (84.27±9.35)μg/L vs (174.72±12.64)μg/L, all P<0.05].Conclusion BCG/PSN might be beneficial for the treatment of atopie dermatitis-like skin lesions in Nc/Nga mice by enhancing the secretion of IL-12 and IFN-γ and suppressing the synthesis of IgE.
