Objective To investigate the effect of induced aborion on stage of labor and placental abnormality of primiparous women during parturition. Methods Birth process and abnormal placenta during labor for 74 women with a history of induced abortion (observation group) and 102 women without a history of induced abortion ( control group) in their first parities were collected and compared. Results The third stage of labor of the observation group was (10.75 ±2.64) min,longer than (8.12 ±3.26)min of the control group,the difference had statistical significance(P ＜0.05). The rate of placenta adhesion,placental remnants and low lying placenta of the observation group were 13.52%, 10.81% and 8.11% respectively, significantly higher than 2.95 %, 1.96% and 0.98% in the control group(P ＜0. 05). Conclusion It was demonstrated that induced aborion had obvious untoward effect on pregnancy such as prolonged third stage of labor and increased incidence of placental abnormalities. So, it was necessary to prevent induced aborion for primiparous women.

OBJECTIVE:To investigate the effects of aerosol inhalation of ambroxol combined with gentamicin on postopera-tive related indexes of esophageal cancer patients. METHODS:60 patients underwent esophageal cancer operation were retrospec-tive analyzed and divided into control group(30 cases)and observation group(30 cases)according to drug use. Three days before surgery,control group was given 5% Glucose injection 250 mL intravenously,twice a day;observation group was given Ambrox-ol hydrochloride injection 50 mL added into 5% Glucose injection 250 mL intravenously,twice a day. After operation,both groups were given anti-inflammatory and analgesic drugs. Control group was additionally given aerosol inhalation of Gentamicin sulfate in-jection 80000 units added into 0.9% Sodium chloride injection 20 mL,4 times a day. Observation group was additionally given aerosol inhalation of Ambroxol hydrochloride injection 10 mL added into 0.9% Sodium chloride injection 20 mL,4 times a day, on the basis of control group. Both groups were treated for 5 days. The occurrence of postoperative pulmonary complications were compared between 2 groups. The levels of CRP,TNF-α,PaO2,SaO2,oxygenation index (PaO2/FiO2),the occurrence of ADR were observed before and after operation. RESULTS:The total incidence of postoperative pulmonary complications in observation group was significantly lower than control group,with statistical significance(P<0.05). Before operation,there was no statistical significance in the levels of CRP,TNF-α,PaO2,SaO2 and PaO2/FiO2 between 2 groups(P>0.05). After operation,the levels of CRP and TNF-α in 2 groups were significantly lower than before operation;the observation group was significantly lower than the control group. PaO2,SaO2 and PaO2/FiO2 of 2 groups were sig-nificantly higher than before operation;the observation group was significantly higher than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2groups during medication. CONCLUSIONS:The aerosol inhalation of ambroxol combined with gentamicin can reduce postopera-tive inflammatory factors of esophageal cancer patients,and promotes the recovery of respiratory function without increasing the in-cidence of ADR.

Objective:To explore the effect of instant blood glucose monitoring system (FGM) in perioperative blood glucose management in patients with hip fracture complicated with diabetes mellitus, and to provide guidance for perioperative blood glucose management.Methods:A total of 100 patients with hip fracture complicated with diabetes mellitus treated in the Department of Orthopaedics, Gongli Hospital, Pudong New Area, Shanghai from July 2018 to July 2020 were selected as subjects.The patients were divided into experimental group and control group by random digits table method with 50 cases in each group. The patients in both groups adopted the mode of multidisciplinary cooperation.The experimental group was used to monitor blood glucose based on FGM, and traditional blood glucose monitoring was used in the control group. The waiting time before operation, the pain caused by blood glucose acupuncture, the satisfaction of patients and medical staff, the blood glucose level at different time points and the incidence of adverse reactions were compared between the two groups.Results:The waiting time before operation, the proportion of patients with moderate and severe pain after acupuncture and the incidence of hyperglycemia in the experimental group were (2.58 ± 1.30) d, 2% (1/50) and 30% (15/50), respectively, the control group were (3.67 ± 1.59) d, 22% (11/50) and 50% (25/50), respectively. The differences were statistically significant( t value was -2.087, χ2 values were 9.470, 4.170, P<0.05). The satisfaction of patients and medical staff in the experimental group were (46.43 ± 1.87), (46.58 ± 2.10) points, respectively, the control group were (40.67 ± 3.24), (43.84 ± 2.92) points, respectively.The differences were statistically significant( t values were 8.441, 8.087, P<0.05). There was no significant difference in fasting blood glucose, 2-hour postprandial blood glucose and pre-bedtime blood glucose between the two groups( P>0.05). Conclusions:The application of FGM can realize the continuous blood glucose monitoring and management of patients,making the blood glucose reach the standard more quickly and smoothly, meanwhile it may effectively shorten the waiting time before operation and reduce the acupuncture pain of blood glucose monitoring and recognize patients with concealed abnormal blood glucose. The application can improve the satisfaction of patients and medical staff, and promote the rapid recovery of patients as well.

Objective To construct human surfactant protein B (SP-B) gene promoter luciferase reporter plasmids and detect their transcriptional activities in H441 cells.Methods (1)The fragment of SP-B promoter (-218/+ 435 bp) was acquired from human genome DNA by polymerase chain reaction (PCR) amplification and then was inserted into pGM-T vector by the T4 DNA ligase.The vector was transfected into TOP10 E.coli.The positive clone was identified by DNA sequencing.The identified target SP-B promoter sequence was cloned into pGL3-basic vector to construct the recombinant vector pGL3-basic-SP-B-promoter and was identified by enzyme digestion and sequencing; (2)The pGL3-basic-SP-B-promoter vector was converted into pGL4.17-SP-B-promoter vector through enzyme digestion.The identified recombinant vectors and control plasmid pRL-TK were transfected into H441 cells by lipofectamine 2000,and luciferase assays was performed using the dual-luciferase reporter assay system.Results The sequences of SP-B promoter in the recombinant luciferase reporter plasmids were consistent with the one published on Genebank.The firefly/renilla luciferase activity ratio of pGL3-basic/pGL4.17-SP-B-promoter vector (2.8 ± 1.1,66.5±3.8) was significantly higher than pGL3-Basic,pGL4.17 control vector (0.2 ±0.1,4.3 ±0.4) with statistical significance (t =4.182,27.419,P =0.000),respectively.The SP-B promoter activity of pGL4.17-SP-B-promoter vector was significantly higher than pGL3-basic-SP-B-promoter vector (t =27.712,P =0.000).Conclusions The pGL3-basic/pGL4.17-SP-B-promoter vectors are successfully constructed with SP-B promoter activity in H441 cells and pGL4.17-SP-B-promoter vector is the better choice for further study with higher luciferase activity.

Objective To observe the effects of different antithrombotic interventions on the changes of plasma lysophosphatidic acid (LPA) level in patients with nonvalvular atrial fibrillation (NVAF) and to provide the basis for clinical antithrombotic therapy. Methods A total of 235 patients with NVAF who did not receive antithrombotic therapy diagnosed by clinical and auxiliary examinations were randomly allocated to receive aspirin (100 mg/d) plus dipyridamole (100 mg/d) (n =76), aspirin (100 mg/d) plus fixed-dose warfarin (1.25 mg/d) (n =79), and dose-adjusted warfarin (international normalized ratio (INR) range of 1.5 to 2. 1) (n =80). They gore redivided into <60, 60-75, and ≥76 year-old groups according to their age. The plasma LPA levels were measured and compared before treatment and 2 and 6 weeks after treatment. Results 1he plasma LPA levels were decreased more significantly in the aspirin plus fixed-dose group than those in the aspirin plus dipyridamole and dose-adjusted warfarin groups (all P < 0.01). Two and 6 weeks after treatment with aspirin plus dipyridamole in the < 60 year-old group, the plasma LPA levels were significantly lower than those before treatment (all P<0. 01). Two and6 weeks after treatment with aspirin plus fixed-dose warfarin in the < 60 year-old group, the plasma LPA levels were significantly lower than those before treatment (all P <0. 01). Two and 6 weeks after treatment with aspirin plus fixed-dose warfarin in the 60-75 year-old group, the plasma LPA levels were significantly lover than those before treatment (all P <0.01). Two and 6 weeks after the treatment with dose-adjusted warfarin (INR 1.5-2. 1) in patients in each age group, the plasma LPA levels were significantly lower than those before treatment. Conclusions 1he different antithromhotic therapeutic modalities have different effects on platelet activation in patients with NVAF in different age groups. The patients in the < 60 year-old group can receive aspirin plus dipyridamole, the patients in the < 75 year-old group can receive aspirin plus fix-dose warfarin, and the patients > 75 year-old, dose-adjusted warfarin (INR 1. 5-2. 1) should he recommend.

Objective To investigate the changes of plasma lysephosphatidic acid (LPA) or acidic phospholipids (AP) levels in patients with nonvalvular atrial fibrillation(NVAF) or NVAF associated with silent brain infarction (SBI) and to provide biochemistry evidence to antithrombotic therapy. Methods Plasma LPA/AP levels was examined in blood freshly sampled in 235 cases of NVAF who were not receiving any antithrombotic therapy, 116 cases SBI who were not with NVAF and 120 cases healthy volunteers as control enrolled in the LPA and stroke prevention study. Plasma LPA was assayed by measuring its inorganic phosphorus after separation by chromatograph. Meanwhile, the platelet activation in NVAF or (and) SBI were observed. Results SBI was found in 31.5% of the participants with NVAF, and in 37.6% of the elderly NVAF subjects (age60 years old). LPA/AP levels were significantly increased in NVAF with SBI group((3.78±0.61) μmol/L) compared with controls ((2.66±0.49) μmol/L, 95% CI 3.47-4.21,P = 0.000), NVAF without SBI group ((3.29±0.57) μmol/L, 95 % CI 3.01-3.76, P = 0.008), SBI without NVAF group((3.17±0.54) μmol/L, P=0.004). The platelet activation was significantly higherin NVAF with SBI group, the odds ratio (95% CI) was 21.39(10.17 to 45.02),than those in NVAF without SBI group (P<0.01). Conclusion The plasma LPA/AP levels were significantly elevated in NVAF or NVAF with SBI, NVAF contributes to the risk of SBI. Platelet activation may play an important role in the pathogenesis of thromboembolism in NVAF and the measurement of LPA reflects activation of platelets in vivo and may be a useful marker for the diagnosis of thrombosis or prothrombotic states.Consideration of the role of antiplatelet therapy should be given when choosing antithrombotic therapy to NVAF-associated ischemic stroke.
