With polyethylene glycol vitamin E succinate (TPGS) as the carrier materials, and berberine hydrochloride ( BER) as model drug, we formed berberine hydrochloride (BER) -loaded TPGS nanomicells (BER-PMs) using filming-rehydration method to improve its solubility and in vitro anti-tumor effect. The transmission electron microscope (TEM) was used to observe the particle appearance; particle detector was used to detect the diameter and Zeta potential; and ultracentrifugation was utilized to determine the encapsulation efficiency (EE) and drug-loading (DD); dynamic dialysis method was used to study the in vitro release behavior of BER-PMs, and the anti-tumor activity against MCF-7 cells was determined by MTT method. Results showed that the average particle size of BER-PMs was (12.45 ± 1.46) nm; particle size was uniform and spherical; drug loading and encapsulation efficiency were (5.7 ± 0.22)% and (95.67 ± 5.35)%, respectively. Zeta potential was (-1.12 ± 0.23) mV; release rate within 24 h was 37.20% and 41.14% respectively in pH 7.4 and pH 6.5 phosphate buffer in vitro; compared with BER, BER-PMs can significantly inhibit MCF-7 cell proliferation (P < 0.05), promote cell apoptosis and improve the anti-tumor activity of BER in vitro. Therefore, the formed berberine hydrochloride micelle can more effectively promote the apoptosis of MCF-7 cell, and improve the drug's in vitro anti-tumor effect.

Objective To evaluate the association between bradycardia and neurological sequel in patients with restoration of spontaneous circulation (ROSC) after cardiopulmonary resuscitation (CPR) during targeted body temperature management (TTM).Methods Forty-three unconscious patients with ROSC after CPR were treated with TTP.The patients were cooled with therapeutic hypothermia to body temperature target range (32-34°C) after cardiac arrest and divided into bradycardia and control groups depending on the lowest heart rate less than 50 beats/min and more than or equal to 50 beats/min respcetively at that time.The bispectral index (BIS) and the neuron-specific enolase (NSE) values were respectively recorded at the following intervals,0h (h0)、24h (h24)、48h (h48)、72h (h72) after ICU admission.Neurological outcome was defined according to the Pittsburgh cerebral performance category (CPC) at 3 months after ICU discharge.Results Compared with the control group,during TTM the bispectral index levels were significantly higher in the bradycardia group at h0,h48,h72 after admission,(h0 bradycardia group 73.0 ± 12.3;control group 58.0 ± 18.6,P ＜0.01)、(h48 bradycardia group 71.4 ± 21.2;control group 46.3 ± 18.9,P ＜ 0.01)、(h72 bradycardia group 78.6 ± 24.6;control group 51.8 ± 24.1,P =0.01).The neuron-specific enolase level in bradycardia group was significantly lower than that in control group on day3 (118.8 ± 118.8 ng/mL vs.248.3 ± 191.9 ng/mL,P =0.02).The level of CPC in the bradycardia group was significantly higher than that in the control group (P =0.046).Conclusions Patients with bradycardia during TTM had favorable neurological outcome,which could provide evidence for clinical treatment and prognostic evaluation of the patients.

Objective To explore clinical features and antimicrobial resistance of Klebsiella pneumoniae (K.pneumoniae) lower respiratory tract infection(LRTI) in children.Methods Clinical data of 107 children with K.pneumoniae LRTI confirmed by sputum culture from January to December 2015 were analyzed retrospectively.Results 62.62% of children with LRTI were aged less than 6 months and 64.49% episodes occurred in autumn and winter.All cases had cough and 39 had fever, the main complications were type I respiratory failure, type Ⅱ respiratory failure, cardiac insufficiency, and electrolyte disturbance, 39 cases(36.45%) had complications involving two systems, 5 cases(4.67%)had complications involving three systems,47 cases (43.93%) met the diagnostic criteria of severe pneumonia.43 cases (40.19%) had primary underlying diseases, the major were congenital heart disease, preterm and low birth weight, and malnutrition.Children with imipenem-resistant bacteria infection were more prone to develop extrapulmonary complications than those with non-resistant pathogenic infection.The resistance rate of K.pneumoniae to amikacin was the lowest(9.35%).90 cases were recovered and markedly effective, 11 cases were effective, 4 cases were not healed and voluntarily discharged from hospital, and 2 cases died.Conclusion Children aged less than 6 months and with underlying diseases are prone to develop LRTI, and complications are more.

Objective To observe the efficacy of cytokine induced killer (CIK) cells combined with radiofrequency ablmion (RFA) in treatment of liver metastases.Methods 23 patients were treated with CIK plus RFA, while 27 patients with RFA.Tumot markers and CD3+、CD4+、CD8+、CD4+/CD8+ were tested before and after treatment.Recurrence rate and Kamofsky score were also evaluated.Results The local recurrence rate in the study group was lower (13.04% vs.40.74%)(P<0.05),CD3+、CD4+、and CD4+/CD8+ were increased (P<0.01). The percentage of patients with decreased tumor markers and increased Kamofsky is higher (P<0.05);Conclusion The therapy of CIK combined with RFA has better efficacy on liver metastases,can enhance the cellular immune functions and improve the quality of life significantly.

Objective To suty the MRI manifestations of juvenile acute articular cartilage injury of the knee joint.Methods MRI findings of cartilage,subcartilage low signal line and subcarilage bone were analysed retrospectively in 53 juvenile patients (ranged in age from 4~27 years) with acute articular cartilage injury confirmed by arthroscopy.Results Sixty-nine cartilage injuries were showed by MRI in 53 patients,including patellas in 25,femoral lateral condyles in 22,femoral medial condyles in 11,trochlea of the femur in 2,and tibial plateau in 9.Acute articular cartilage injury appeared as pure cartilage fracture in 46, including complete split of the cartilage in 22 sites,partly split of the cartilage in 20 sites,and fissur-like fracture in 4 sites.Osteochondral fracture were observed in 23 sites,including avulsion fracture in 13 and osteochondral subsided in 10.Articular cartilage loose bodies and osteochondral loose bodies were found by MRI in 6 and 13,respectively.Conclusion MRI is the best non-invasive method for studying cartilage injury.

[Summary] A total of 352 pregnant women were selected in Affiliated Hospital of Qingdao University. Serum levels of TSH and FT4 were determined and pregnancy outcome were observed in all subjects. According to the standard of American Thyroid Association(ATA) published in 2011 and the Chinese Guideline of Gestation Thyroid Disease published in 2012, the subjects were grouped into control(0. 1≤TSH≤2. 5 mIU/ L), observation(2. 55. 17 mIU/ L)during first-trimester(T1)and control(0. 2≤TSH≤3. 0 mIU/ L), observation(3. 05. 22 mIU/ L) during second-trimester(T2). The results showed that the rupture of membranes, preterm labor, and total obstetrical adverse events in the observation group were significantly higher than those in control group during T1(all P<0. 05), no statistical significance between control group and treatment group. The rupture of membrances in the observation group was significantly higher compared with control group during T2 ( P < 0. 05), no significant difference in other adverse pregnancy outcomes between these two groups. Compared with control group during T1, the proportion of adverse pregnancy outcomes in observation group during T1 was significantly increased(P<0. 05). The elevated TSH is one of the risk factors for the increased incidence of adverse pregnancy outcomes at the first half of pregnancy, especially during T1. L-T4 treatment reduces the incidence of adverse pregnancy outcomes.
