Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.

Objective To explore the CT features in CD_(117)-weak and CD_(117)-negative gastrointestinal stromal tumors(GIST).Methods The CD_(117)-weak and CD_(117)-negative Gist proved by pathologically and sur- gically in 13 cases were retrospectively analyzed.Results The tumor was located in the stomach in 6 cases, small intestine in 4 cases,colorectum in 2 cases,greater omentum in one case.The most common clinical manifestations were abdominal pain or discomfort in 6 cases,hematemesis or melena in 3 cases.Malignant tu- mors occurred in 8 cases.Benign tumors occurred in 5 cases.A soft tissue was identified in all 13 cases in CT examination.The CT examinations revealed cystic regions and bleeding in 5 cases.Calcification was not noted within the masses in all cases.The mean diameter of benign tumors was 3.4 cm?2.8 cm while that of malig- nant tumor was 7.5 cm?6.2 cm.All the cases underwent operation,the resection rate was 100%.After follow up from 6 months to 4 years in 10 cases,1 case died of tumor recurrence and metastasis,the others survived. Conclusion CD_(117)-weak and CD_(117)-negative Gist occurred more common in the stomach.CT is useful in lo- cation and differentiation of CD_(117)-weak and CD_(117)-negative gastric stromal tumors with regard to benign or malignant.Surgery is the main method for final diagnosis and treatment.

Buluo Buguan Decoction originates from ZHANG Xi-chun's book Yi Xue Zhong Zhong Can Xi Lu, with the functions of astringent, removing blood stasis, and vein relaxing. The original major functions of this decoction are to treat chronic hemoptysis and hematemesis. In long-term clinical practice, Professor SHAO found that the modified decoction showed significant positive outcome in the treatment of hematuria, nocturnal emission, spontaneous sweating, night sweats, and allergic purpura nephritis, with good efficacy.

Hedgehog signaling pathway is a conserved and important signaling pathway involved in proliferation and differentiation of many types of cells. Latest studies have found that Hedgehog signaling pathway may induce MSCs osteoblast differentiation by increasing the expression of the Runx2 and Osx and inhibit MSCs differentiate to adipocyte. Hedgehog signaling pathway may also promote osteoblast proliferation by regulating cyclin. This review summarizes the mechanism that Hedgehog signaling pathway regulates osteoblast differentiation and proliferation,and concludes that Hedgehog signaling pathway can regulate bone metabolism. It might provide new ideas for the treatment of osteoporosis.

Objective To explore the effects of forepaw sensorimotor deprivation in early life on hippocampus-dependent spatial reference learning and memory in rats. Methods Newborn SD rats were randomly assigned to experiment group (deprivation of forepaw sensorimotor function, n=53) and control group(n=55). Rats of postnatal day 13 (PN13) in experiment group were seleeted, and models of forepaw sensorimotor deprivation were established by microsurgical technique. Open field tests and Morris water maze tests were performed during the time periods of PN25(PN21-31), PN35 (PN31-39), PN45(PN41-50) and PN60(PN56-64) to evaluate the locomotor activity and spatial reference learning and memory, respectively. Results In open field tests, there was no significant difference in parameters of locomotor activity and exploratory behavior between the two groups (P>0.05). In Morris water maze tests, eontrol group performed significantly better than experiment group during training sessions and probe tests on PN25 and PN35 (P<0.05). While on PN45, although there was no significant difference between the two groups during training sessions, control group performed significantly better than experiment group during probe tests (P<0.05). Conclusion The deprivation of forepaw sensorimotor in early life has no signifieant effect on the locomotor activity and exploratory behavior of rats, but can impair the spatial reference learning and memory.

Objective To evaluate the feasibility of using comprehensive geriatric assessment (CGA) in estimating if standard dose treatment is fit for the elderly patients with diffuse large B cell lymphoma.Methods.Comprehensive geriatric assessments including three assessments of activity of daily living,instrumental activity of daily living and comorbidity scoring according to Cumulative Illness Rating Score for Geriatrics were adopted to assess if standard dose treatment is fit for the elderly patients in our prospective study.Thirty seven patients with diffuse large B cell lymphoma,aged ＞70 years were enrolled in the study,and grouped into fit,unfit and frail groups according to comprehensive geriatric assessment scoring and their age.The treatment protocolswere not determined by comprehensive geriatric assessment scores,but by clinical judgments made by clinicians based on their clinical experience and disease features.The clinically effective response and overall survival (OS) were analyzed in the three groups.Results According to CGA scores,patients were grouped into fit [21 cases (56.8％)],unfit [7 (18.9％)] and frail [9 (24.3％)].37 cases received 213 courses of treatment at average 5.76 courses per case.The overall response (complete / partial remission) rates were [85.7％(18/21) vs.28.6％ (2/7) vs.44.4％ (4/9),x2=9.69,P=0.008] and median survival times were (44 months vs.10 months vs.9 months;x2 =7.03,P=0.03) among fit,unfit and frail groups with statistically significant differences.Total effective rate (achieving all clinical targets) in fit group of 21 cases were 100 ％ (12/12)with receiving standard dose therapy,and 66.7％ of(6/9)with low dose therapy(P=0.06).Overall response rate(total/partial remission) [85.7％(18/21) vs.28.6％(2/7) vs.44.4％(4/9),x2=9.69,P=0.008] and median survival (44 months vs.10 months vs.9 months;x2 =7.03,P=0.03) amongfit,unfit and frail groups.In fit group,the two-year overall survival was higher in patients receiving standard dose treatment than receivingpalliativetreatment,with statistical significance [83.3 ％ (10/12) vs.33.3 ％ (3/9),P =0.032],without significant hematologic toxicity observed between the subgroups.Conclusions Comprehensive geriatric assessment can identify if elderly patients diffuse large B cell lymphoma can acquire a satisfactory curative effect from a standard dose treatment ofimmunochemotherapy.

Objective To evaluate the value of 18F-FDG PET/CT in early in vivo monitoring of tumor response to cisplatin,and analyze the relationship between 18F-FDG uptake in tumor and the corresponding pathological changes.Methods Thirty VX2 rabbits were divided into 5 groups by random number table with 6 in each group,including 4 treatment groups and 1 control group.18F-FDG PET/CT were performed before and after (6,12,24 and 36 h post-injection respectively) intravenous administration of cisplatin (7 mg/kg) in the treatment groups,respectively.The control group was injected with physiological saline followed by 18F-FDG PET/CT.The ROI was drawn and the SUVmax and T/NT ratio were calculated.The tumor necrosis rate and apoptosis index were observed by histopathologic examination.Paired t test,GamesHowell test and arcuation correlation analysis were used to analyze the data.Results Significant differences were found in SUVmax and T/NT of the control group before and after injection of physiological saline (6.58±1.67 vs 9.77±2.45,52.93±3.90 vs 29.34±3.31;t=-5.480,17.593,both P＜0.05).18F-FDG uptake decreased after 6 h post-injection of cisplatin,with the mean SUVmax decrease rate of (11.83±8.89) ％ and the mean T/NT decrease rate of (59.00±8.22)％.In the 24 h treatment group,18F-FDG uptake decreased most,and the mean SUVmax decrease rate was (42.33±33.80)％,the mean T/NT decrease rate was (83.50± 7.69) ％.The SUVmax and T/NT of those 2 groups were significantly different from those of the control group,and no difference was found between the 2 treatment groups(all P＜0.05).The changes of SUVmax and T/NT were positively correlated with apoptosis index and tumor necrosis rate (r=0.750,0.794,0.804,0.874,all P＜0.05).Conclusion 18F-FDG PET/CT is a sensitive method for monitoring early response to tumor chemotherapy in VX2 tumor-bearing rabbits at 24 h after treatment.
