We report the management and maternal and neonatal outcomes of four cases of delayed interval delivery after cervical cerclage in twin pregnancies, who hospitalized in Shanghai First Maternity and Infant Hospital from year 2017 to 2018. Four patients with dichorionic diamniotic twin pregnancies all presented with gradually weakened uterine contractions after spontaneous vaginal delivery of twin 1. After informed consent, the patients received cervical cerclage at 2 to 3 days after delivery when the maternal and fetal conditions were stable, to delay delivery of twin 2. The gestational weeks at delivery of twin 1 were 25 +4, 23 +1, 27 +1, and 23 weeks, which were noted for 30 +1, 32 +6, 31 +4, and 24 weeks for twin 2, respectively. Delayed delivery intervals were 32, 69, 31 and 7 d. Three of the four twin 2 survived, with Apgar score ≥ 8 at 1 minute and birth weight of 1 390, 2 290 and 1 620 g. During a 2-year follow-up, no developmental abnormalities were observed in the children, and no serious maternal complications were found, including severe infection, bleeding or cervical laceration.

Objective To investigate the influence of arsenic trioxide (AS2 O3 )in the vasculogenic mimicry (VM ) of HepG2 cells, and to preliminary clarify the possible mechanism of inhibition of AS2 O3 on the VM. Methods Themean inhibitory concentration (IC50 )of AS2 O3 72 h after treatment of HepG2 cells was calculated by CCK-8 assay.The HepG2 cells were cultured on 3-D Matrigel and randomly divided into control group, 1/2 IC50 AS2 O3 group and IC50 AS2 O3 group.IPP software was used to calculate the number,length and area of VM,and the expression levels of VM-related proteins VE-cadherin and MMP-2, apoptotic-related protein caspase-3 and proliferation-related protein PCNA were detected by Western blotting method.Results The IC50 of AS2 O3 was 10μmol·L-1 72 h after treatment of HepG2 cells.The number,length and area of VM in 1/2 IC50 and IC50 AS2 O3 groups were significantly lower than those in control group (P<0.01);the number,length and area of VM in IC50 AS2 O3 group were also lower than those in 1/2 IC50 AS2 O3 group (P<0.05).Compared with control group,the expression levels of VE-cadherin and MMP-2 in 1/2 IC50 and IC50 AS2 O3 groups were decreased (P<0.05),and the expression levels of caspase-3 and PCNA had no significant change (P>0.05).Conclusion AS2 O3 can inhibit the forming of VM of HepG2 cells,which indicated that its mechanism may be related to inhibiting the expressions of VE-cadherin and MMP-2 .

Objective To describe and analyze the distribution of medical expenditure of Liaoning province in 2014 in terms of population beneficiary based on the System of Health Accounts 2011(SHA 2011).Methods By means of multistage and stratified sampling, a total of 252 medical institutions were selected from four cities in Liaoning province according to their economic status and geographical distribution.Macro data including the outpatient income and hospitalization income were taken into account, to calculate the beneficiary population of the province in 2014 according to SHA2011.Results GBD classification found that the highest medical expenditure category was non-communicable diseases, accounting for 63.02% in total medical expenditure.ICD classification found that respiratory disease as consuming the highest medical expenses (43.76%).The average medical expenditure of the elderly population was the highest per person, up to 3 041.70 yuan per person.Conclusions Medical expenses of non-communicable diseases, respiratory disease and elderly population were still high.Thus we need to emphasize disease prevention, and take efficient measures against such key diseases to curb the medical expenses.The elderly population calls for specific and effective measures to reduce their medical expenses.

Objective:To investigate the association of muscle mass loss with atherosclerosis in elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 322 patients with T2DM aged≥60 years old were divided into muscle mass loss group( n=152) and non-muscle mass loss group( n=170) according to their appendicular skeletal muscle mass index(ASMI). All participants underwent physical examination, dual-energy X-ray absorptiometry check, carotid and lower extremity ultrasound, as well as laboratory tests. Results:Among 322 patients, 49(15.22%) patients were suffered from sarcopenia and 152(47.2%) patients with reduced muscle mass. The carotid and lower extremity atherosclerosis grades in the muscle mass loss group were significantly higher than those in the non-muscle mass loss group( P<0.05), with lower body mass index(BMI), T-score, ASMI, uric acid, and homeostasis model assessment of insulin resistance index( P<0.05). Multivariate logistic regression analysis showed that carotid atherosclerosis and lower extremity atherosclerosis were risk factors for muscle mass loss while BMI and 25-(OH)D 3 were protective factors for muscle mass loss. There existed a consistency in carotid atherosclerosis grade and lower extremity atherosclerosis grade of elderly patients with T2DM( P<0.01). Conclusion:Atherosclerosis has a predictive value for early sarcopenia in elderly patients with T2DM.

BACKGROUND:There are several reports about the application of fresh bone marrow aspirate being injected directly to repair partial ligament injury, but the application about fresh bone marrow aspirate directly being planted on scaffolds to build tissue-engineered ligament is rarely mentioned.
OBJECTIVE:To evaluate the feasibility of applying fresh bone marrow aspirate planted directly on scaffolds to construct tissue-engineered ligament
METHODS:We constructed fibroin fiber/smal intestinal submucosa composite scaffold, then planting fresh bone marrow directly to built bone marrow seeding group and planting seed cel s (bone marrow mesenchymal stem cel s) on the scaffold to built cel seeding group. The control group had no treatment. After that, we detected the density of cel adhesion, cel proliferation ability and extracel ular matrix secretion. Then, the composite in the bone marrow seeding group was implanted into the broken anterior cruciate ligament in rabbits, and material biocompatibility in vivo was evaluated after 12 weeks.
RESULTS AND CONCLUSION:After 4 hours of incubation, bone marrow seeding group was significantly higher than the cel seeding group in cel adhesion density and proliferation rate (P<0.05). Bone marrow seeding group and cel seeding group showed higher type I, III col agen secretion compared with the control group (P<0.05), but the col agen secretion of bone marrow seeding group and cel seeding group showed no significant difference. Composite cel scaffold implantation in vivo did not cause fatal immune rejection and severe inflammatory reaction, and no significant ligament regeneration and vascularization occurred. These findings indicate that fresh bone marrow aspirate can be seeded directly on scaffolds to construct tissue-engineered ligament, and the short-term biocompatibility in vivo is good.

Objective To investigate the predictive value of left ventricular diastolic function on mechanical ventilation weaning in patients with left ventricular ejection fraction (LVEF) > 0.50.Methods A retrospective case control study was conducted. Sixty-five patients with LVEF > 0.50 undergoing mechanical ventilation for more than 48 hours admitted to surgery intensive care unit (ICU) of China-Japan Friendship Hospital from June 2014 to December 2016 were enrolled. The clinical data and parameters of echocardiography before spontaneous breathing trial (SBT) were collected. The possible relationship between left ventricular diastolic function and the results of weaning was analyzed according to analysis of blood flow filling parameters of mitral valve orifice. According to the grading standard of left ventricular diastolic function, the patients were divided into normal, mild (level 1) and moderate to severe (level 2-3) groups, and the outcomes of weaning were compared among the groups. Then patients were also divided into two groups of weaning successfully and weaning failure, and the clinical data and left ventricular diastolic function parameters of patients were compared between the two groups. The predictive value of left ventricular diastolic function on results of weaning was evaluated with receiver operating characteristic curve (ROC).Results Sixty-five patients were enrolled and 28 patients (43.1%) failed weaning, 22 patients failed the first SBT and 6 required reintubation within 48 hours, 31 of the patients presented normal left ventricular diastolic function, 9 of patients presented mild diastolic dysfunction, and 25 of them presented moderate to severe diastolic dysfunction. So with the gradual increase of the severity of diastolic dysfunction, the rate of weaning failure was gradually increased, which was 16.1%, 44.6% and 76.0% respectively (χ2 = 20.240,P = 0.001). Patients who failed weaning presented evidence of increased left ventricular filling pressures at pre-SBT, by demonstrating decreased deceleration time of E (DTE, s: 180.4±5.1vs. 196.8±4.0,t = 2.567,P = 0.013), increased left ventricular mitral valve diastolic early and late filling velocity ratio (E/A: 1.47±0.08 vs. 1.14±0.05, t = 3.827,P = 0.000), increased lateral, septal and averaged left ventricular mitral valve diastolic early velocity and maximal velocity of mitral annulus in early diastolic velocity ratio (E/Em: 10.26±0.52 vs. 7.28±0.41,t = 4.535, P = 0.000; 10.08±0.58 vs. 8.16±0.40,t = 2.797,P = 0.007; 10.17±0.48比7.72±0.35,t = 4.231,P = 0.000), and the rapid shallow breathing index (RSBI) was also increased significantly (61.7±3.6 vs. 50.6±2.7,t = 2.507, P = 0.015). It was shown by ROC curve analysis that the basic left ventricular diastolic function at pre-SBT had the diagnostic performance in predicting the outcome of weaning from mechanical ventilation, especially E/A and lateral E/Em. Pre-SBT values of E/A greater than 1.2 and lateral E/Em greater than 7.9 predicted weaning failure with an area under the ROC curve (AUC), sensitivity, and specificity of 0.81±0.06 and 0.85±0.06, 82.6% and 91.3%, 81.4% and 80.7%, respectively, and the AUC was higher than RSBI (0.70±0.07). The AUC of combination of E/A > 1.2 and lateral E/Em > 7.9predicting weaning failure was 0.86±0.05 with a sensitivity of 78.3% and a specificity of 93.6%.Conclusions The results suggest that left ventricular diastolic dysfunction is significantly associated with weaning outcome in critical patients with LVEF > 0.50. The combination of E/A ratio greater than 1.2 and E/Em ratio greater than 7.9 may identify patients at high risk of weaning failure.
