OBJECTIVE To investigate the mechanism of Cichorium glandulosum in the treatment of liver fibrosis by using network pharmacology and experimental validation. METHODS A "component-target-pathway" network was constructed with the help of TCMSP, Pubchem, SwissTargetPrediction and Genecards databases, and the STRING database was used to predict the targets of Cichorium glandulosum against liver fibrosis. KEGG and GO enrichment analysis was performed in the DAVID database, and molecular docking of active ingredients and key targets was docked in AUTODOCK. PDGF-BB was used to induce activation of cells and verify the effects of six compounds, including quercetin, quercetin, chicoric acid, caffeic acid, chlorogenic acid, and isochlorogenic acid, on the proliferation, apoptosis, and liver fibrosis indicators of HSC-T6 cells. Western blotting was used to detect the expression of Ras, ERK1, ERK2, C-fos, and JNK proteins in HSC-T6 cells. RESULTS Network pharmacology screened 239 common targets between the components and liver fibrosis, PPI analysis showed that SRC, STAT3, HSP90AA1 and other targets were key targets, KEGG analysis showed that the pathways affected by Cichorium glandulosum included cancer pathways, metabolic pathways, etc. GO analysis predicted that Cichorium glandulosum mainly affected processes such as signal transduction. The molecular docking results showed that the target that could bind well with the components MAPK1, and the components that could bind well with the target aesculetin, caffeic acid and chlorogenic acid. Compared with the model group, the inhibition effect of the six compounds on PDGF-BB-induced HSC-T6 cell activation was stronger, and all 6 compounds had the effects to reverse the index of liver fibrosis, in which aesculetin had the strongest activity(P<0.01). The expression of Ras, ERK1, ERK2, C-fos, and JNK in HSC-T6 cells decreased after the interventions of 6 compounds. CONCLUSION Each component of Cichorium glandulosum has different anti liver fibrosis effects, which are related to the inhibition of ERK/RAS pathway activation.

Objective:To analyze the influence of E-Coaching self-management model on health behavior change in perimenopausal women.Methods:In this randomized controlled trial, 230 perimenopausal women who participated in health management prograam in the Health Management Center of Hangzhou Wuyunshan Hospital from January 2020 to October 2021 were selected as study objects by convenience sampling method. The subjects were divided into the experimental group and the control group with random number table (115 cases in each group). The experimental group was managed by health coaches with E-Coaching self-management model, and the control group was routinely managed by health managers. The intervention lasted for 6 months. Finally, 29 cases were lost to follow-up due to the failure of the subjects to comply with protocol requirements or voluntary withdrawal. So, a total of 201 subjects were included in the analysis (107 cases in the experimental group and 94 cases in the control group). χ2 test and t test were used to analyze the differences in modified Kupperman symptom score, perimenopausal knowledge and belief, regular exercise and dietary healthy behavior stage between the two groups. And the influence of E-Coaching self-management model on health behavior change in perimenopausal women was analyzed too. Results:After the intervention, the total score of modified Kupperman scale and the scores of insomnia, anxiety and fatigue in the experimental group were all lower than those in the control group [(7.36±2.91) vs (10.01±2.78) points, (0.49±1.13) vs (1.27±1.20) points, (0.80±0.99) vs (1.68±1.39) points, (0.67±0.55) vs (0.93±0.64) points]( t=6.553, 4.785, 5.219, 3.013, all P<0.05); and the total score of knowledge and belief questionnaire and the score of knowledge or belief dimension in the experimental group were significantly higher than those in control group [(25.15±1.55) vs (21.05±1.64) points, (9.61±0.56) vs (9.03±0.68) points, (15.54±1.53) vs (12.02±1.28) points] ( t=-18.238, -6.570, -17.801, all P<0.05). After the intervention, the proportions of the experimental group in the precontemplation and contemplation stage of exercise and diet were both significantly lower than those before intervention ( χ2=116.616, 139.964, both P<0.001), and were lower than those in the control group (the proportion of precontemplation stage of exercise was 7.5% vs 38.3%, and the contemplation stage of exercise was 26.2% vs 34.0%, χ2=38.330; the proportion of precontemplation stage of diet was 3.7% vs 23.4%, and the contemplation stage of diet was 18.7% vs 29.8%, χ2=25.399; all P<0.001). After the intervention, the proportion of the subjects in the preparation stage and action stage the experimental group were significantly higher than those before intervention ( χ2=116.616, 139.964, both P<0.001), and were higher than those in the control group (the proportion in preparation stage of exercise 18.7% vs 8.5%, and the action stage of exercise 47.7% vs 19.1%, χ2=38.330; the proportion in preparation stage of diet 20.6% vs 14.9%, and the action stage of diet 57.0% vs 31.9%, χ2=25.399; all P<0.001). Conclusion:E-Coaching self-management model can improve women′s perimenopausal symptoms in certain degrees, it improves their understanding of perimenopausal knowledge, enhances self-management beliefs and promotes healthy behavior changes.

Zhuye Shigaotang， first recorded in ZHANG Zhongjing's Synopsis of the Golden Chamber （《金匮要略》）， is a commonly used prescription for treating heat syndrome in modern times. However， physicians of the past dynasties have different opinions on the mechanism of Zhuye Shigaotang in disease treatment. Based on HUANG Yuanyu's theory of Qi circulation， this paper holds that the root cause of the diseases treated by Zhuye Shigaotang is the deficiency of spleen and stomach in the middle energizer and the dysfunction of ascending and descending. The failure of Yin ascending leads to the failure of Yang transformation， and the failure of Yang descending causes the failure of Yin generation. As a result， heat and fire become predominant in the heart， lung， and stomach， which causes Qi counterflow and fluid consumption. Based on this pathogenesis， Zhuye Shigaotang is mainly composed of pungent， warm， sweet， and cold herbs. The combination of these herbs can protect the spleen and stomach and recover the Qi movement in the middle energizer， thereby clearing heat and fire， descending Qi， and promoting the generation of Qi and fluid. In clinical practice， this prescription can be applied to treating the syndromes of deficiency in spleen and stomach， dysfunction of middle energizer in transportation， dysfunction of ascending and descending， excessive heat and fire， and Qi counterflow and fluid consumption. The interpretation of Zhuye Shigaotang from the theory of Qi circulation can provide a new idea for differentiating syndromes， seeking causes， and developing prescriptions， which broadens the scope of clinical application of this prescription and provides a reference for interpreting ZHANG Zhongjing's method of compatibility.

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.

Pituitary abscess is a rare but potentially life-threatening disease. Headache, visual disturbance, and hypopituitarism are the most common presenting symptoms of pituitary abscess. On magnetic resonance imaging(MRI), pituitary abscess may present as a round sellar cystic lesion, hypo- or isointense on T1 imaging and hyper- or isointense on T2 imaging with peripheral gadolinium enhancement. Diagnosis usually is made during surgical exploration when pus is found in a cystic lesion. The mainstay of treatment is transsphenoidal surgical resection in combination with antibiotic therapy, although a craniotomy approach is warranted in select conditions. Here we report 3 cases of pituitary abscess in our hospital and review the literatures.

Objective:It is yet to be clarified whether pylorus-preserving gastrectomy (PPG) for early gastric cancer will bring the risk of radical tumor resection, whether it will increase the incidence of postoperative complications, and how much is the benefit of the quality of life for patients after surgery, these issues are not clear. This meta-analysis aims to evaluate the efficacy and safety of pylorus-preserving gastrectomy (PPG) for early middle gastric cancer.Methods:The Chinese and English literatures about PPG and distal gastrectomy (DG) for early gastric cancer were searched from PubMed, Embase, The Cochrane Library, Web of Science, CNKI net and Wanfang database. Literature inclusion criteria: (1) Prospective or retrospective cohort study of PPG and DG for early middle-third gastric cancer published publicly; (2) Patients with early middle-third gastric cancer; (3) The enrolled literatures include at least one of the following outcome indicators: the efficacy indicators include gallstone, residual gastritis, bile reflux, delayed gastric emptying, dumping syndrome, reflux esophagitis and overall complication; the long-term prognostic indicators include 5-year survival rate and 5-year tumor recurrence. Literature exclusion criteria: (1) Reviews, case reports, conference summaries and other non-control studies; (2) Repeated published studies, incomplete studies and unextractable studies; (3) The depth of tumor invasion exceeding submucosa. The search time ended in July 2020. The basic information and evaluation indicators included in the article were extracted. The retrospective study was evaluated using Newcastle-Ottawa literature quality evaluation scale. The prospective randomized controlled study was evaluated using Jadad modified scale. Meta-analysis was performed using Review Manager 5.3. Publication bias was assessed using funnel map. Publication bias was tested using Egger tools.Results:A total of 717 literatures were retrieved, and 17 literatures were enrolled finally, including 2 randomized controlled trials and 15 retrospective studies. A total of 2427 patients were enrolled, including 948 in PPG group and 1479 in DG group. The meta-analysis of the efficacy indicators showed that there were significant differences in gallstones incidence (OR=0.42, 95% CI: 0.28-0.65, P<0.001), residual gastritis incidence (OR=0.50, 95% CI: 0.32-0.77, P=0.002), bile reflux incidence (OR=0.30, 95% CI: 0.20-0.45, P<0.001), delayed gastric emptying incidence (OR=2.40, 95% CI:1.67-3.45, P<0.001), and postoperative dumping syndrome incidence (OR=0.28, 95% CI: 0.15-0.51, P<0.001), while there were no significant differences in postoperative overall complications (OR=0.97, 95% CI: 0.69-1.35, P=0.840), reflux esophagitis incidence (OR=0.79, 95% CI: 0.39-1.61, P=0.520) between the two groups. The meta-analysis of the long-term prognostic indicators showed that no significant differences of 5-year survival (OR=1.02, 95% CI: 0.61-1.71, P=0.940) or 5-year tumor recurrence (OR=0.77, 95% CI: 0.36-1.68, P=0.520) were observed between the two groups. Conclusion:The incidences of gallstone, residual gastritis, dumping syndrome, bile reflux are lower after PPG in early gastric cancer, while the postoperative overall complications and long-term survival are comparable between PPG and DG, indicating that PPG is quite safe and feasible.

The inhibitory effect of NACOS on dyslipidemia and potential molecular mechanisms by in vitro and in vivo experiments were investigated. For in vitro study, four experimental groups were designed by using HepG2 cells, including the control group, palmitic acid (PA) treatment alone group, NACOS treatment alone group and NACOS + PA treatment group. For in vivo study, male C57BL/6 mice were divided into four groups (n=5) at random including the normal control group (NCD), high fat diet (HFD) group, NACOS treatment alone group, NACOS+HFD group, which were treated for 20 weeks. The used methods in this study were as follows: the observation of lipid droplet deposition in HepG2 cells by oil red O staining, the detection of mRNA levels of lipid metabolism-related regulators and inflammatory cytokine by RT-PCR method, the monitoring of MAPKs and PI3K/Akt pathway activation by Western blotting method. The in vitro study shows that, NACOS had no toxicity on the viability of HepG2 cells at 25-100 μg/mL and significantly reduced the deposition of lipid droplet. Also, based on both in vitro and in vivo investigation, NACOS evidently down-regulated the expression of lipid metabolism-related regulators (PGC1α, Cox5b, Mcad) and inflammatory cytokine (IL-1β) at mRNA level (P<0.05 or 0.01), and suppressed the activation of p38, ERK1/2 and Akt in HepG2 cells and lever tissues from HFD-fed mice (P<0.05 or 0.01). Based on the above, NACOS may inhibit the oxidation of liver mitochondrial fatty acid and the lipid biosynthesis, block the inflammatory responses and prevent the HepG2 cells and C57BL/6 mice from lipidemia.
