Patients with hepatocellular carcinoma (HCC) and bone metastasis (BM) suffer from greatly reduced life quality and a dismal prognosis. However, BM in HCC has long been overlooked possibly due to its relatively low prevalence in previous decades. To date, no consensus or guidelines have been reached or formulated for the prevention and management of HCC BM. Our narrative review manifests the increasing incidence of HCC BM to sound the alarm for additional attention. The risk factors, diagnosis, prognosis, and therapeutic approaches of HCC BM are detailed to provide a panoramic view of this disease to clinicians and specialists. We further delineate an informative cancer bone metastatic cascade based on evidence from recent studies and point out the main factors responsible for the tumor-associated disruption of bone homeostasis and the formation of skeletal cancer lesions. We also present the advances in the pathological and molecular mechanisms of HCC BM to shed light on translational opportunities. Dilemmas and challenges in the treatment and investigation of HCC BM are outlined and discussed to encourage further endeavors in the exploration of underlying pathogenic and molecular mechanisms, as well as the development of novel effective therapies for HCC patients with BM.

Objective:To compare the clinical characteristics of critically ill pregnant women admitted to the intensive care unit (ICU) with different admission methods, in order to make more effective and rational use of ICU resources.Methods:A retrospective study was conducted. The clinical data of critically ill pregnant women admitted to ICU of Peking University Third Hospital from January 2006 to July 2019 were analyzed. According to the admission mode to ICU, the pregnant women were divided into emergency admission group (transferred to ICU on the same day or the next day due to critical illness) and planned admission group (transferred to ICU 2 days after admitting in obstetric ward). The clinical characteristics of ICU critical pregnant women, such as the incidence, causes of admission, severity of the disease, main treatment measures, mortality, and medical expenses were collected, and a comparative analysis between the two groups was performed.Results:During the nearly 14 years, a total of 576 critical pregnant women in ICU were enrolled, accounting for 0.8% (576/71 790) of the total number of obstetric inpatients and 4.6% (576/12 412) of the total number of ICU inpatients. Seven maternal deaths accounted for 1.2% of all critically pregnant women transferred to ICU, and the overall mortality of pregnant women was 10/100 thousand. Of the 576 critically pregnant women, there were 327 patients (56.8%) in the emergency admission group and 249 patients (43.2%) in the planned admission group. Compared with the planned admission group, the proportion of elective cesarean section in the emergency admission group was significantly lower (17.7% vs. 94.0%, P < 0.01), and the proportion of emergency cesarean section was significantly higher (65.1% vs. 2.4%, P < 0.01), the acute physiology and chronic health evaluation (APACHE Ⅱ, APACHE Ⅲ) scores, simplified acute physiology score Ⅱ (SAPS Ⅱ) and Marshall score were significantly higher [APACHE Ⅱ score: 6.0 (4.0, 9.8) vs. 4.0 (3.0, 7.0), APACHE Ⅲ score: 14.0 (11.0, 20.3) vs. 12.0 (9.0, 16.0), SAPS Ⅱ score: 8 (0, 12) vs. 3 (0, 8), Marshall score: 2 (1, 4) vs. 1 (1, 3), all P < 0.01]. The length of ICU stay in the emergency admission group was significantly longer than that in the planned admission group [days: 2 (1, 5) vs. 2 (1, 3), P < 0.01], and the total length of hospital stay was significantly shorter [days: 9 (7, 13) vs. 13 (10, 18), P < 0.01]. Both in the emergency admission group and the planned admission group, obstetric factors were the main reason for admission, 60.9% (199/327) and 70.3% (175/249), respectively. The proportion of postpartum hemorrhage was the highest [35.2% (115/327) and 57.0% (142/249)], followed by preeclampsia/eclampsia [7.0% (23/327) and 7.6% (19/249)]. Only 7 of the 19 critically pregnant women with puerperal infection were planned admission. All 21 patients with acute fatty liver of pregnancy (AFLP) during pregnancy were emergency admission. Among the emergency and planned admission patients, 73 patients (22.3%) and 42 patients (16.9%) required mechanical ventilation (duration of mechanical ventilation > 24 hours), 99 patients (30.3%) and 35 patients (14.1%) needed vasoactive agents, 67 patients (20.5%) and 20 patients (8.0%) received hemodynamic monitoring, and 123 patients (37.6%) and 154 patients (61.8%) were given anticoagulation therapy, respectively. In terms of severity score of critical pregnant women, there were significant differences in APACHE Ⅱ, APACHE Ⅲ, SAPS Ⅱ and Marshall scores of pregnant women with different diseases. Among them, the APACHE Ⅲ, SAPS Ⅱ and Marshall scores of AFLP were the highest [21.0 (15.0, 32.5), 12.0 (6.0, 16.5) and 6.0 (3.5, 8.0), respectively]. The APACHE Ⅱ and APACHE Ⅲ scores of postpartum hemorrhage were the lowest [4.0 (3.0, 7.0), 12.0 (10.0, 16.0)]. The SAPS Ⅱ score of pneumonia was the lowest [2.0 (0, 14.0)]. The Marshall score for puerperal infection was the lowest [1.0 (0, 3.0)]. In terms of the total medical expenses, the cost in the emergency admission group was significantly lower than that in the planned admission group [10 thousand Yuan: 3.1 (2.0, 4.7) vs. 4.1 (2.9, 5.8), P < 0.05]. Conclusions:Compared with the critically ill pregnant women who planned to be admitted to ICU, the patients emergency admitted to ICU were more complicated and urgent, and the severity of the condition was scored higher. At present, the severity scoring system commonly used in ICU can only partly evaluate the severity of critically ill pregnant women, therefore, it is necessary to design the specific severity scoring system for critically ill pregnant women to effectively and rationally use the precious ICU resources.

Objective:To explore the value of pressure-strain loop (PSL) for non-invasive quantitative assessment of left ventricular myocardial work index (GWI), global work efficiency (GWE), global constructive work (GCW), global wasted work (GWW) in the evaluation of left ventricular myocardial work in patients with hypertrophic cardiomyopathy (HCM).Methods:Thirty-one HCM patients (HCM group) and 36 healthy volunteers (control group) from December 2018 to September 2019 in Henan Provincial People′s Hospital were selected. Relevant clinical data were collected, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), left ventricular end systolic diameter (LVEDs), left atrial diameter (LAD), the maximum wall thickness (MWT), left ventricular mass index (LVMI), the global longitudinal strain (GLS), the peak strain dispersion(PSD) and GWI, GWE, GCW and GWW between the two groups were compared.Results:Compared with the control group, MWT, LAD, E/e′, LVMI in HCM group were significantly increased (all P<0.05); left ventricular myocardial functional parameters of GLS, GWI, GWE, GCW were significantly decreased, and GWW and PSD were significantly increased (all P<0.05). Left ventricular GLS, PSD and GWI, GCW, GWW, GWE have better repeatability within the observer and between observers. ICC within the observer were 0.852, 0.707, 0.917, 0.955, 0.675, 0.618, respectively. And their ICC between observers were 0.837, 0.631, 0.927, 0.944, 0.555, 0.670, respectively. Correlation analysis showed that GLS was positively correlated with GWI, GWE, and GCW ( r=0.765, 0.737, 0.815; all P<0.001), and negatively correlated with GWW and PSD ( r=-0.517, -0.606; all P<0.001). Conclusions:The left ventricular GWI, GWE and GCW decreased in HCM patients, while the GWW increased. PSL can evaluate the damage of left ventricular myocardial work in HCM patients.

Objective: To investigate the effects of clustered warming intervention on spontaneous hypothermia and coagulation function in patients with emergency trauma. Methods: A total of 118 cases of emergency trauma patients admitted from January 2017 to December 2018 in Changzhou Second People′s Hospital were selected as subjects. According to the time of admission, there were 62 cases in the control group from January 2017 to December 2017 and 56 cases in the treatment group from January 2018 to December 2018. The control group used routine emergency nursing intervention and warming measures, and the treatment group combined with clustered warming intervention. The changes of body temperature, coagulation function, spontaneous hypothermia and prognosis were compared between the two groups. Results: When entering the Emergency Department and entering the Emergency Department for 60 minutes, the body temperature of the emergency trauma patients in the treatment group were (36.41±0.75) and (36.74±0.65)℃, and the control group were (35.42±0.80) and (35.54±0.76)℃. The difference between the two groups was statistically significant (t value was 6.914, 9.168, P<0.01). After entering the Emergency Department for 60 minutes, the activated partial thromboplastin time, prothrombin time, and thrombin time in the treatment group were (35.24±2.25), (13.56±1.02), (17.45±1.52) s, and the control group was (39.45±3.42), (15.12±1.34), (19.20±1.23) s. The difference between the two groups was statistically significant (t value was 7.802, 7.058, 6093, P<0.01). The incidence of spontaneous hypothermia and duration of hypothermia in the treatment group were 16.07%(9/56), (7.32±1.14) h, and that in the control group was 41.94%(26/62) and (18.42±3.20) h. The difference between the two groups was statistically significant (χ² value was 9.432, t value was 24.579, P<0.01). The incidence of chills, infection and death in the observation group was 16.07%(9/56), 7.14%(4/56), and 5.36%(3/56), and that in the control group was 51.61%(32/62), 24.19%(15/62), and 17.74%(11/62). The difference between the two groups was statistically significant (χ² value was 16.393, 6.322, 4.316, P< 0.05 or 0.01). Conclusions Clustered warming intervention can help prevent the risk of spontaneous hypothermia in emergency trauma patients, antagonize coagulation dysfunction and improve patient prognosis.

Objective To investigate the relationship between the serum level of vancomycin and its clinical efficacy as well as adverse reactions in adult patient so as to provide recommendations for clinical management. Methods An open observational research was performed from 1st July 2013 to 31st December 2017 in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, which recruited the adult patients who were infected with Gram positive (G+) bacteria and treated with vancomycin. The initial dose was decided by the patient's creatinine clearance rate, and the treating dose was directed by the serum drug concentration and the patient's clinical response. By recording the associated clinical information (pathogen eradication, blood test results, adverse reactions, etc.), the clinical outcome and adverse reactions for vancomycin to treat G+bacterial infections were analyzed. Results Eighty-nine cases who meet research standards were finally recruited, with 67.42% of male patients, and an average age of (50.5±17.9) years. The most common type of infection was bloodstream infection (61.80%), followed by low respiratory infection (17.98%). Infections caused by Staphylococcus aureus accounted for 39.33%. The bacterial eradication rate was 89.89% (80/89) and the total effective rate was 77.53% (69/89). The effective rate was 80.30% (53/66) with minimum inhibitory concentration (MIC) < 2 mg/L vs. 69.57% (16/23) with MIC ≥ 2 mg/L, the difference was not statistically significant (χ2= 1.129, P = 0.288). The effective rate was 72.92% (35/48) with trough levels <10 mg/L vs. 82.93% (34/41) with trough levels ≥ 10 mg/L, the difference was not statistically significant (χ2= 1.272, P = 0.259). There were 4 cases of vancomycin associated nephrotoxicity, the incidence of nephrotoxicity was 4.49%, and the vancomycin serum trough levels were 17.22-28.53 mg/L. There were 33 cases of liver dysfunction, and elevated γ-glutamine transferase, alkaline phosphatase and aspartate aminotransferase were most common. There were 2 cases of neutropenia and 2 patients appeared rash during vancomycin period. Conclusions Treatment outcomes were similar regardless of vancomycin MIC and serum trough level. The incidence of vancomycin associated nephrotoxicity rises apparently when serum trough level is over 15 mg/L. Clinical Trial Registry Chinese Clinical Trail Registry, ChiCTR-OPC-16007920.

OBJECTIVE:To study induction effect of euphornin on the apoptosis of cervical cancer Hela cells and its mechanism. METHODS:The cervical cancer Hela cells were divided into blank control group,cisplatin group(positive control, 10 mg/L) and euphornin low-dose,medium-dose and high-dose groups (50,100,200 mg/L). They were treated with relevant medicine. The inhibitory effect of Hela cells proliferation was tested by MTT assay after 24,48,72 h of medicine treatment. The apoptotic rate of Hela cells was measured by flow cytometry after 48 h of medicine treatment. Morphology of nucleus was detected by Hoechst 33258 staining. The protein expression of Cyt-C,Bcl-2,Bax,Caspase-3,Caspase-8,Caspase-9 and Caspase-10 were detected by Western blot assay. RESULTS:Compared with blank control group,inhibitory rate of cell proliferation and cell apoptosis rate were increased significantly in cisplatin group and euphornin groups(P＜0.05 or P＜0.01),and obvious staining, deformation,shrinking,fragmentation or apoptotic bodies was found in nucleus. Compared with blank control group,the protein expression levels of Cyt-C,Caspase-8 and Caspase-9 in euphornin low-dose,medium-dose and high-dose groups were increased significantly,while the protein expression level of Bcl-2 and Bcl-2/Bax ratio were decreased significantly(P＜0.05 or P＜0.01);the protein expression levels of Bax,Caspase-3 and Caspase-10 in euphornin medium-dose and high-dose groups were increased significantly(P＜0.05 or P＜0.01). CONCLUSIONS:Euphornin can significantly inhibit the proliferation of Hela cell and promote cell apoptosis,the effect of which will be achieved by activating the Caspase-dependent mitochondrion apoptosis pathway.
