OBJECTIVETo investigate the role of Src family kinases (Fgr, Hck, Lyn) and the major protein kinase C substrate SSeCKS in non-alcoholic steatohepatitis (NASH) and determine the possible mechanism regulating differential expression.

METHODSKupffer cells were stimulated with CCL4 and effect on SSeCKS, Hck, Fgr, and Lyn expression was detected by real-time reverse transcription-PCR. Male Sprague-Dawley rats were used to create a NASH model by feeing a high fat diet. The modeled rats were divided into a model group and a normal group. After sacrifice, the extent of hepatic steatosis and inflammation was assessed, and the expression levels of SSeCKS and Hck, Fgr, Lyn were detected by immunohistochemical staining.

RESULTSExpression of Lyn and Hck was decreased in the CCL4-stimulated Kupffer cells and the change in expression level was positively associated with levels of inflammatory stimuli (P < 0.01). The change in expression of SSeCKS in the CCL4-stimulated Kupffer cells was negatively correlated with inflammatory stimuli (P < 0.01). Fgr expression was very low in the unstimulated Kupffer cells and was not affected by the exposure to inflammatory stimuli. The number of inflammatory cells in the liver tissues of rars were negatively correlated with expression of Lyn, Hck and SSeCKS (P < 0.01), with low negative correlation for Lyn (r =-0.398, P < 0.01) and moderate negative correlation for Hck (r=-0.508, P < 0.01); the Lyn and Hck expression levels were highly positively correlated (r =0.942, P < 0.01).

CONCLUSIONSrc family kinases (Lyn, Hck and Fgr) and SSeCKS are involved in development and progression of NASH, and their differential expression patterns are associated to a certain extent. The factors may represent potential targets of therapy for NASH-related inflammation.

Objective To investigate the effects of CD4+CD25high regulatory T cells(Treg)and the imbalance of helper T lymphocyte subsets(Th1/Th2)on the immunological mechanism of IgA nephropathy(IgAN)patients. Methods The percentage of Treg and helper T cells subpopulation (Th1/Th2)in the peripheral blood of IgAN patients and healthy controls was examined by flow cytometry.The FOXP3 expression was detected through intracellular staining.The correlation of Treg or Th1/Th2 with clinical parameters of IgAN was analyzed by Spearman or Pearson rank correlation test. Results The percentages of Treg and Th2 cells were significantly higher in peripheral blood of IgAN patients compared to that of healthy controls[Treg (2.14±0.82)%vs[1.59±0.53)%,Th2(2.57±0.72)%vs(1.81±1.10)%,all P＜0.05].Th1/Th2 ratio was significantly reduced in IgAN patients(5.75±1.89 vs 12.73±9.79,P＜0.05).The percentage of circulating Treg cells was positively correlated with serunl IgA concentration(r=0.397,P＜0.05),and was negatively correlated with eGFR(r=-0.376,P＜0.05).The percentage of circulating Th2 cells was positively correlated with serum IgA(r=0.468,P＜0.05). Conclusions There is a disorder of T lymphocyte population in the peripheral blood of IgAN patients.The increased Treg and Th2 cells may play an important role in the pathogenesis of IgAN.

OBJECTIVETo study the correlation between clinically detected serum galectin-3 levels and prognosis of liver failure.

METHODSFifty-five patients diagnosed with liver failure were administered a combined modality therapy and followed up until death or for 6 months. Fifty-five patients with liver failure were administered a combined modality therapy and followed up until death or for 6 months. In addition, 30 patients with chronic hepatitis B (CHB) and 30 healthy volunteers were matched for use as controls. Serum galectin-3 levels were detected at baseline and last follow-up visit and compared between groups by statistical analysis.

RESULTSAt baseline, the CHB group had a significantly higher level of serum galectin-3 than the healthy control group (F=2.701, P less than 0.01). However, the galectin-3 level 5 of the liver failure group was significantly higher than that of both the CHB group (F=8.121, P less than 0.01) and the healthy control group (F=11.231, P less than 0.01). When patients within the liver failure group were divided by survival and death occurring during the 6-month follow-up period, the patients who died (n=28) were found to have a significantly higher level of serum galectin-3 than the surviving patients (n=27) (P less than 0.01). The area under the curve of ROC curve is 0.766, and cut off value is 0.246 5 ng/ml.

CONCLUSIONThe level of serum galectin-3 is positively correlated with risk of death in patients with liver failure. Up-regulation of galectin-3 may act as a protective factor in patients with severe liver injury.

Liver failure and intestinal barrier injury, especially intestinal microflora imbalance, interacts as both the cause and effect of each other. Intestinal barrier injury is observed during liver failure, including the injuries of chemical, mechanical, immune, and microbial barriers, and meanwhile, gut dysbiosis, increased bacterial endotoxins, and abnormal bile acid metabolism may affect hepatocyte regeneration, increase complications, and aggravate the conditions of liver failure. The maintenance of intestinal barrier function should be taken seriously in the treatment of liver failure, and the treatment targeting intestinal barrier injury, especially microecological disturbance, is a promising method.

ObjectiveTo investigate the quality of life and demands of family members of patients with mental disorders in hospice care， in order to create a better medical care environment for patients to meet their demands. MethodsA total of 205 family members of patients with mental disorders in hospice care were consecutively sampled from two special psychiatric hospitals in Deyang city with convenient sampling method. The Chinese version of WHO Quality of Life-BREF （WHOQOL-BREF） and Critical Care Family Needs Inventory （CCFNI） were used to assess the quality of life and demands of family members. ResultsAmong the patients' family members， WHOQOL-BREF scored （68.08±9.98） in the physiological field， （63.82±9.39） in the psychological field， （70.73±12.61） in the social relations field， and （64.24±11.87） in the environmental field. Compared with the domestic general population， there were significant differences in other fields except the physiological field （t=3.066， 9.845， 16.109， P<0.01）. In CCFNI， the score of condition assurance factor was （3.20±0.41）， information support was （2.86±0.50）， proximity to patients was （2.79±0.46）， self comfort was （2.35±0.47）， and medical staff support was （2.60±0.44）. ConclusionThe quality of life of the family members of patients with mental disorders in hospice care may be higher than that of the general population， and their demands mainly focus on the condition assurance and information support.

Corona virus disease 2019 (COVID-19) patients with trauma are at high risk of venous thromboembolism (VTE), which must be taken seriously in the therapeutic processes. Hypercoagulable state is induced by 2019 novel coronavirus (2019-nCoV) in many ways, such as increasing the level of inflammatory factors and fibrinogen, and inducing endothelial cell injury. The venous wall injuries from trauma and operation directly or indirectly trigger off the exogenous coagulation pathway and the microcirculation can be damaged at the same time, which may initiate the exogenous pathway of VTE. Immobilization of limbs and forced bed rest during the treatment of traumatic patients will slow venous blood flow. Chronic non-communicable diseases such as diabetes in the elderly were independent risk factors for VTE. Furthermore, the persistent fever, severe lung disease, respiratory failure, sepsis and invasive technology application add the risk of VTE and the difficulty of treatment. In order to help effective prevention VTE of for COVID-19 patients with trauma, the authors put forward relevant technical suggestions for prevention and nursing of VTE to provide basis for nursing work during pandemic of COVID-19.

OBJECTIVETo explore the efficacy and safety of deferasirox in aplastic anemia (AA)patients with iron overload.

METHODSA single arm, multi- center, prospective, open- label study was conducted to evaluate absolute change in serum ferritin (SF)from baseline to 12 months of deferasirox administration, initially at a dose of 20 mg·kg(-1)·d(-1), and the safety in 64 AA patients with iron overload.

RESULTSAll patients started their deferasirox treatment with a daily dose of 20 mg · kg(-1) ·d(-1). The mean actual dose was (18.6±3.60) mg · kg(-1)·d(-1). The median SF decreased from 4 924 (2 718- 6 765)μg/L at baseline (n=64) to 3 036 (1 474- 5 551)μg/L at 12 months (n=23) with the percentage change from baseline as 38%. A median SF decrease of 651 (126-2 125)μg/L was observed at the end of study in 23 patients who completed 12 months' treatment, the median SF level decreased by 1 167(580-4 806)μg/L [5 271(3 420-8 278)μg/L at baseline; 3 036(1 474-5 551)μg/L after 12 months' treatment; the percentage change from baseline as 42% ] after 12 months of deferasirox treatment. The most common adverse events (AEs) were increased serum creatinine levels (40.98%), gastrointestinal discomfort (40.98%), elevated liver transaminase (ALT: 21.31%; AST: 13.11%)and proteinuria (24.59%). The increased serum creatinine levels were reversible and non-progressive. Of 38 patients with concomitant cyclosporine use, 12(31.8%)patients had two consecutive values >ULN, 10(26.3%)patients had two consecutive values >1.33 baseline values, but only 1(2.6%)patient's serum creatinine increased more than 1.33 baseline values and exceeded ULN. For both AST and ALT, no patients experienced two post- baseline values >5 ×ULN or >10 × ULN during the whole study. In AA patients with low baseline PLT count (less than 50 × 10(9)/L), there was no decrease for median PLT level during 12 months' treatment period.

CONCLUSIONSAA patients with iron overload could achieve satisfactory efficacy of iron chelation by deferasirox treatment. The drug was well tolerated with a clinically manageable safety profile and no major adverse events.

ObjectiveTo investigate the clinical features and outcomes of critically ill pregnant and parturient women with chronic hepatitis B virus （HBV） infection， and to provide clinical experience for the rescue of critically ill pregnant and parturient women and the prevention and treatment of the severe exacerbation of liver disease. MethodsA total of 41 pregnant and parturient women with chronic HBV infection who were admitted to Department of Critical Care Medicine， Nanjing Second Hospital， from March 2013 to March 2023 were enrolled in this study， and their clinical data were collected through the electronic medical record system of hospital to summarize the main causes of transfer to the intensive care unit （ICU）， the causes of death， and treatment. The independent-samples 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. ResultsAmong the 41 patients， 13 （31.71%） did not receive regular antenatal examination and 8 （19.51%） with a high viral load （HBV DNA ≥2×10⁵ IU/mL） did not receive antiviral therapy. Cesarean section was the main mode of delivery in 32 patients （78.05%）； 23 patients （56.10%） had premature delivery， and 5 patients died （12.20%）. The top three causes of transfer to the ICU were liver failure， postpartum hemorrhage， and hypertensive disorders of pregnancy. Liver failure mainly occurred in late pregnancy， with hepatic encephalopathy as the most common complication （28.57%） and intrahepatic cholestasis of pregnancy as the most common comorbidity （21.43%）； among the 14 patients with liver failure， 6 （42.86%） received regular antenatal examination， and 13 （92.86%） did not receive antiviral therapy before admission. The mean length of ICU stay was 3.31±1.65 days for the patients with postpartum hemorrhage， among whom the patients with severe liver disease had coagulation disorders before delivery， which were difficult to correct after 48 hours of treatment. ConclusionPregnant and parturient women with chronic HBV infection tend to have complex conditions and a relatively high mortality rate. For pregnant and parturient women with chronic HBV infection， assessment of liver status， regular antenatal examination， and timely antiviral therapy are of vital importance to reduce severe exacerbation and mortality rate.
