OBJECTIVETo observe preventive and therapeutic effect of Yifei Jianpi Recipe (YJR) on chronic obstructive pulmonary disease (COPD) model rats and to explore its mechanism from the way of airway inflammation and airway mucus hypersecretion.

METHODSThe COPD rat model was established by using cigarette smoking combined with intratracheal injection of lipopolysaccharide (LPS). Male SD rats were randomly divided into the blank control group (control group), the model group, the YJR group, 6 in each group. Forced vital capacity (FVC), forced expiratory volume in 0. 1 second (FEV0. 1), FEVO. 1/FVC, peak expiratory flow (PEF) was tested by lung function device. Pathological changes of bronchi and lung tissues were observed by HE staining. Airway Goblet cells were observed using AB-PAS staining. Contents of IL-8, IL-17, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), nuclear factor KB (NF-KB), mucin 5AC (Muc5AC), and Toll-like receptor 4 (TLR4) in rat airway were detected by immunohistochemical assay. mRNA expressions of TLR4 and Muc5AC in bronchi and lung tissues were detected by real-time quantitative PCR (RT qPCR).

RESULTSChanges of bronchi and lung tissues in the model group rats were consistent with typical pathological manifestations of COPD. Compared with the model group, the degree of lung injury was significantly alleviated in the YJR group. Compared with the control group, FVC, FEV0. 1, FEVO. I/FVC, and PEF were decreased (P <0. 01), contents of IL-8, IL-17, and TNF-α in BALF were significantly increased (P <0. 01), protein expressions of ICAM-1, NF-KB, Muc5AC, and TLR4, mRNA expression levels of Muc5AC and TLR4 in bronchi and lung tissues were also significantly increased in the model group (P <0. 01). Compared with the model group, FVC, FEV0. 1, FEV0. 1/FVC, and PEF were significantly increased in the YJR group (P <0. 01, P <0. 05), but the rest indices were significantly lowered (P <0. 01, P <0. 05).

CONCLUSIONYJR could decrease contents of IL-8, IL-17, and TNF-α in BALF of COPD model rats, inhibit protein expression levels of ICAM-1, NF-κB, Muc5AC, and TLR4.in airway and lung tissues, thus playing preventive and therapeutic roles by reducing airway inflammation and airway mucus hypersecretion.

OBJECTIVETo explore the therapeutic effect of qi benefiting blood activating method (QB-BAM) on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with blood stasis syndrome (BSS) by observing its effect on plasma fibrinogen (Fg) and D-dimer (D-D) levels.

METHODSSixty AECOPD patients with BSS were randomly assigned to the treated group and the control group, 30 in each group. All patients received conventional therapy for AECOPD. Those in the treated group were additionally injected with Shengmai Injection and Tanshinone IIA Injection. Clinical efficacy and indices including levels of Fg, D-D, PaO2, and PaCO2 were measured and compared before and after treatment.

RESULTSThe effective rate was 93.3% (28/30 cases) in the treated group, higher than that of the control group [73.3% (22/30 cases) , P < 0.05]. There was no significant difference in all indices between the treated group and the control group before treatment (P >0.05). After treatment all indices were significantly improved in the two groups (P < 0.01). But in the treated group levels of Fg and D-D decreased more and levels of PaO2 increased more (P < 0.01). Plasma levels of Fg and D-D levels were negatively correlated with PaO2 (r = -0.493, r = -0.438, P < 0.01) before treatment, and also negatively correlated with PaO2 (r = -0.452, r = -0.325, P < 0.01, P < 0.05) after treatment, but they were not significantly correlated with PaCO2 before and after treatment (P >0.05).

CONCLUSIONSQBBAM could play a therapeutic role in improving prethrombotic states of AECOPD patients with BSS. Plasma levels of Fg and D-D were related to the severity of AECOPD.

Objective To investigate the prevalence of low T3 syndrome in patients with acute myocardial infarction(AMI) and explore the effect of low T3 syndrome on outcome of AMI.MethodsThree hundred and thirty-eight patients with AMI admitted to cardiac care unit(CCU) underwent examinations of thyroid function and cardial ultrasound,and were further categorized according to thyroid hormone profile.The records of noninvasive bi-level positive airway pressure(BiPAP)ventilation utilization,length of hospital stay,mortality during hospitalization were evaluated,and the related factors were analysed.ResultsOne hundred and thirty-nine of the 338 patients(41.12%) with AMI complicated with low T3 syndrome.Free triiodothyronine(FT3) was the independent influential factor for length of hospital stay.Low FT3 was significantly correlated with noninvasive BiPAP ventilation utilization and mortality during hospitalization.The average time of follow-up was(21.4?8.1) months.It was revealed by multivariate Cox regression analysis that FT3 was the chief predictor for cumulative death(risk ratio,4.25;95% confidential interval,2.30-7.87),followed by age and left ventricular ejection fraction.ConclusionThe recognition of AMI complicated with low T3 syndrome plays an important role in predicting the disease severity and outcome.

Objective To summarize the experience of multidisciplinary consultation for prenatal fetal deformity, and to explore the mode suitable for China. Methods The Obstetrics and Gynecology Hospital of Fudan University and Children's Hospital of Fudan University established a joint multidisciplinary consultation center, including obstetrics, pediatrics, pediatric surgery, ultrasound and other departments. A total of 3 378 pregnant women visited the consultation center from July 31, 2003 to August 1, 2013. After consultation, treatment was divided into three classes:pregnancy termination, pregnancy continuation and perinatal treatment. Follow-up was made through correspondence and telephone communication. Retrospective analysis on reasons for consultation, fetal structural abnormalities of the classification system, chronological order of abnormalities, gestational weeks of diagnosis, maternal-related factors, treatment and prognosis was performed. Results (1) Reasons for consultation:Among 3 378 women undertaking prenatal multidisciplinary consultation, 3 243 (96.00%) were due to fetal factors, and 135 (4.00%) were due to maternal factors. (2) Classification of fetal structural abnormalities:Among the 3 243 cases undertaking consultation with fetal factors, fetal abnormality was found in 80.85%(2 622/3 243). The most common were neurological abnormalities(23.19%, 608/2 622), followed by urinary tract malformation (20.25%, 531/2 622) and cardiovascular malformation (15.48%, 406/2 622). These were followed by digestive system malformation, limb deformities and space-occupying lesions. There were 156 cases of multiple malformations. (3) Average gestational weeks for diagnosis of fetal deformity:The 2 622 cases of fetal deformity were diagnosed at a mean (26.7± 2.1) of gestational weeks (21.1–30.4 weeks). Urinary tract malformations were detected at (24.0±0.7) weeks, whereas digestive system malformations were detected at (28.3±2.6) weeks. (4) Induced labor:Induced labor cases accounted for 35.66% (935/2 622), among which, 92 cases were fetal intrauterine death and 843 cases were active choice. The several highest induced labor rates resulted from multiple malformations (75.64%, 118/156), abdominal wall defects (62.22%, 28/45), diaphragmatic hernia (61.54%, 24/39), cleft lip and palate (55.32%, 26/47) and cardiovascular malformations (49.51%, 201/406). For nervous system (27.80%, 169/608), urinary tract (25.80%, 137/531) and digestive system malformations (26.94%, 66/245), induced labor rates were <30%. For abdominal lesions (14.04%, 25/178) and sacrococcygeal teratoma (13.64%, 3/22), induced labor rates were<15%. (5) Continuation of pregnancy in 1 687 cases:Cesarean section was conducted in 1 046(61.94%). Neonatal death occurred in 117(6.94%).(6) Perinatal treatment:Twenty-one cases were treated during pregnancy, including thirteen cases with fetal ascites and hydrothorax treated by drainage, five cases with fetal anemia treated by intrauterine transfusion and three cases with fetal tachycardia treated by digoxin. Ten cases were treated by ex-utero intrapartum treatment. After birth, 297 newborns immediately underwent neonatal surgery. Among these, 259 cases underwent radical surgery, eleven palliative surgery, and sixteen elective surgery after follow-up. Conclusions Prenatal multidisciplinary consultation can make comprehensive multidisciplinary assessment of fetal prognosis and improve the diagnosis and treatment of structural malformations.
