OBJECTIVE:To investigate the effects of pharmaceutical intervention after discharge on medication compliance and prognosis of patients with coronary artery disease after percutaneous coronary intervention(PCI) in primary hospital.METHODS:One hundred and eighty patients with coronary artery disease selected from our hospital after PCI during Jan.2012 to May 2015 were divided into test group and control group according to whether the patients received pharmaceutical intervention after discharge,with 90 cases in each group.Control group received conventional pharmaceutical care and discharge education.Test group additionally received pharmaceutical intervention (pharmaceutical service files,telephone follow-up,patient education,etc.) after discharge.Medication compliance and occurrence of cardiovascular events were compared between 2 groups in 1 year after discharge.RESULTS:Within 1 year after discharge,the proportion of patients showing good compliance in test group was higher than control group,the proportion of patients showing partial and non compliance in test group were lower than control group;the inci dence of heart failure and repeated revascularization,hospitalization mortality and total mortality of test group were significantly lower than control group,with statistical significance (P＜0.05).CONCLUSIONS:Pharmaceutical intervention after discharge can improve the medication compliance of coronary artery disease patients after PCI in primary hospital,reduce the occurrence of cardiovascular events and improve the clinical prognosis.

Objective To compare various CT signs of pancreatic carcinoma (PC) and inflammatory pancreatic mass (IPM), and to study the diagnostic value of these signs for distinguishing two diseases. Methods Eigty-five patients with PC and IPM were proved by surgery, fine needle aspiration or other comprehensive methods. These patients underwent non-enhanced and enhanced CT scans. CT findings were analyzed retrospectively. The occurrance rates of various CT signs in these two diseases were analyzed with Fisher test and were compared with the corresponding clinical and operational results as welL Results Among the 85 patients, 66 patients were proved to have PC, and 19 were proved to have IPM. In PC group,58 were corerectly diagnosed with CT, 3 (4. 5% ) were misdiagnosed, and 5 (7.6%) were omitted. In IPM group, 9 were correctly diagnosed with CT and 10 (52. 6% ) were misdiagnosed. The CT findings were as follows: (1) Pancreatic mass with liver metastases, lymph node metastases, encased celiac arteries, and cancer emboli in portal veins just occurred in PC group. (2) The occurrence rates of mass over 3 cm in diameter, clear boundary, low-density area within the mass, pseudocysts, peripancreatie infiltration, ascites, and slight and moderate pancreatic-bile duct dilation in PC group were 90. 91% (60/66), 15.15% ( 10/66), 54. 55% ( 36/66 ), 10. 61% ( 7/66 ), 4. 55% ( 3/66 ), 22. 73% ( 15/66 ), 24. 24% ( 16/66 ), 45.45% (30/66), and 27. 27% (18/66) respectively, the occurrence rates in IPM group were 94. 74% ( 18/19), 15.79% ( 3/19 ), 52. 63% ( 10/19 ), 15.79% ( 3/19 ), 15. 79% ( 3/19 ), 21.05% (4/19), 31.58% (6/19) ,21.05% (4/19), and 5.26% (1/19) respectively.

Objective To compare the differences between the schizophrenics with negative and positive symptoms on prefrontal lobe and thalamus by proton magnetic resonance spectroscopy ( 1 H-MRS). Methods 58 negative subtype and 51 positive subtype schizophrenics were examined at prefrontal lobe and thalamus by multivoxel 1H-MRS before antipsychotic treatment The N-acetylaspartate (NAA), choline-containing compounds ( Cho), and creatine compounds (Cr) were measured and the ratios of NAA/Cr, Cho/Cr were determined. Results On right thalamus,the NAA/Cr ratio in negative subtype patients ( 1.40 ± 0.29 ) demonstrated lower than that in positive subtype ( 1.62 ± 0.33 ), the same phenomenon were appeared on male, female, non-first-episode, with-medicine and without-medicine patients (P ＜ 0.05 or 0.01 ). The Cho/Cr ratio on right thalamus in negative subtype of female,non-first-episode,without-medicine schizophrenics were lower than those in positive subtype (P ＜ 0.05 ).On left prefrontal lobe,left thalamus and right thalamus, the NAA/Cr ratios both in negative subtype and positive subtype schizophrenics were significantly negatively related with age of onset(P＜0. 05 or 0.01 ). In negative subtype schizophrenics,the Cho/Cr ratio on right thalamus was positively related with age of onset ( r = 0. 25, P ＜0.05 ). In negative subtype schizophrenics of non-first-episode, without-medicine, the correlation was negative between the NAA/Cr ratio and the course of disease( r= -0.48, -0.46, P＜0.05 ) ,and was positive between Cho/Cr ratio and the course of disease on right thalamus( r= 0.58,0.56, P＜ 0.01 ). Conlusion Compared with positive subtype schizophrenics,negative subtype schizophrenics have greater impairments on 1 H-MRS on right thalamus. The course of disease has greater effects on 1 H-MRS in negative subtype schizophrenics.

Objective To analyze the ultrasonic features of interrupted inferior vena cava (IVC) and its relationship with related deformities so as to improve the prenatal diagnosis of isomerism.Methods Pregnant women who received prenatal care in Peking University People's Hospital or who were referred to our hospital for suspected malformation of fetus between January 2010 and December 2013 were enrolled in this study.Fetal echocardiography and abdominal transverse section were performed routinely.Spatio-temporal image correlation technology was used to further clarify interrupted IVC if azygos vein was broadened or IVC disappeared in the fetal abdominal transverse sections.Based on the presence of cardiac structural abnormalities,interrupted IVC was divided into isolated IVC interruption and complex IVC interruption.Neonatal echocardiography was performed in women with continued pregnancies.In women with terminated pregnancy,fetus was autopsied after induced labor.Results In total,12 cases of interrupted IVC were diagnosed,including 5 cases of isolated IVC interruption with full-term delivery and 7 cases of complex IVC interruption.Neonatal echocardiography,abdominal ultrasound were all normal in the 5 cases of isolated IVC interruption except for 3 cases complicated with sistus inversus viscerum.All the 7 cases of complex IVC interruption had induced labor because of some congenital cardiac abnormalities.Autopsy showed that 6 cases had left isomerism,and 1 case had right isomerism.Conclusions Interrupted IVC can be easily identified in prenatal diagnosis due to the typical ultrasonic features.Complication with some congenital cardiac abnormalities often indicates isomerism,especially left isomerism.

Objective:To explore the risk factors for esophageal stricture after endoscopic resection (ER) of large-area early esophageal cancer (≥3/4 circumferential mucosal defect).Methods:A total of 63 cases of large-area early esophageal cancer treated with ER in the Digestive Endoscopy Center of the First Medical Center of PLA General Hospital from May 2009 to April 2016 were included in the retrospective analysis. They were divided into stricture group (32 cases) and non-stricture group (31 cases) according to the occurrence of postoperative esophageal stenosis. T-test or Chi square test was conducted to compare the indicators between the two groups. Indicators of P<0.05 and potential indicators from the clinical perspective were included in multivariate logistic regression analysis. Results:Univariate analysis showed that the length of lesion, the degree of mucosal defect around the wound and the injury of muscularis propria were associated with esophageal stricture after ER ( P<0.05). The above 3 indicators were included in the multivariate logistic regression analysis, together with 3 other indicators, i. e. preventive measures for stenosis, pathological type, and en bloc resection. The results showed that more than 7/8 circumferential mucosal defect around the wound (VS 3/4-<7/8 circumferential: P=0.028, OR=0.317, 95% CI:0.114-0.884) and no preventive measures ( P=0.002, OR=0.153, 95% CI:0.046-0.512) were independent risk factors for esophageal stricture after ER of large-area early esophageal cancer. Conclusion:Circumferential mucosa defect≥7/8 is the main factor leading to esophagus stricture after large-area early esophagus carcinoma. And appropriate preventive measures can effectively reduce the incidence of postoperative stenosis after ER.

Objective To identify the metabolite levels in prefrontal lobe and thalamus in patients of schizophrenia with proton magnetic resonance spectroscopy (1H-MRS). Methods Twenty-six schizophrenics with medicine-free for at least 7 d and 28 normal controls were assessed in this study. All subjects underwent examination of multi-voxel 1H-MRS on prefrontal lobe and thalamus within 24 h. The NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho+Cr) were determined. Results Compared with the controls, the NAA/Cr ratio of schizophrenics was significantly lower in left prefrontal lobe and bilateral thalamus (all P＜0.05). No statistical difference of NAA/(Cho+Cr) ratio and the Cho/Cr ratio was found between two groups. Conclusion Abnormalities in neuronal function and/or integrity are present at left prefrontal lobe and bilateral thalamus simultaneously in schizophrenics.

Objective:To explore the clinical efficacy of Gemcitabine in combination with radiotherapy for elderly patients with cervical cancer .Methods:From December 2016 to August 2018, 84 elderly patients with advanced cervical cancer receiving treatment in our hospital were enrolled.As a randomized controlled study, patients were divided into the radiotherapy-alone group and the combined therapy group.Patients in the combined therapy group was given radiotherapy and Gemcitabine.The short- and long-term efficacy, and the rate of adverse reactions were evaluated for the two groups.Results:Tumors in both groups were effectively controlled after treatment.The overall rate of effectiveness in the radiotherapy-alone group was significantly lower than that in the combined therapy group(67.6% vs.87.2%, χ2=4.756, P=0.029). The combined therapy group was associated with a significantly higher survival rate(89.4% vs.59.5%, χ2=10.204, P=0.001), a local recurrence-free rate(83.0% vs.54.1%, χ2=8.286, P=0.004), and a distant metastasis-free survival rate(83.0% vs.56.8%, χ2=6.975, P=0.008), compared with the radiotherapy-alone group.Additionally, the incidence of leukopenia was higher in the combined therapy group than in the radiotherapy-alone group(38.3% vs.13.5%, χ2=8.396, P=0.011). Conclusion:The combination of radiotherapy with Gemcitabine for the treatment of advanced cervical cancer in elderly patients can effectively enhance control on cancerous tissues, improve the long-term survival rate, and reduce the risk of local recurrence.

Objective To study the dynamic changes of blood carnitine and acylcarnitine levels in preterm infants during parenteral and enteral nutritional support,and the relationship between carnitine status and nutritional patterns,gestational age (GA) and weight gain.Method From January 2017 to December 2017,preterm infants admitted to the neonatal intensive care unit (NICU) within 24 hours after birth and received parenteral nutrition support were enrolled.They were assigned into 4 groups according to their GA:ultra-premature infants (＜ 28 weeks),very premature infants (28 ～ 31 weeks),mid premature infants (32 ～ 33 weeks) and late premature infants (34 ～ 36 weeks).They were assigned into 2 groups according to their average daily weight gain:＜ 15 g/(kg · d) group and ≥15 g/(kg · d) group.Blood samples were collected and examined as dried-blood spot specimens on filter paper for four times:after born,given total parenteral nutrition,given enteral combined parenteral nutrition,and given total parenteral nutrition.The concentrations of free carnitine and acylcarnitine were detected using liquid chromatographytandem mass spectrometry (LC-MS/MS).SPSS 21.0 statistical software was used for statistical analysis.Result A total of 124 preterm infants and 410 samples were collected.As the infants experienced gradual transition from parenteral nutrition to enteral nutrition,the free carnitine and most acylcarnitines levels were decreasing (C3,C4,C10DC,C12,C12∶1,C12DC,C14,C16,C16∶ 1,C16-OH and C18,P＜0.05).Preterm infants with small GA showed higher levels of C4-OH (P =0.001) and C5 (P =0.001).Preterm infants with lower velocity of weight gain showed lower concentration of C5-OH (P =0.006) in the early postnatal period.Conclusion Free carnitine and acylcarnitine in preterm infants during the early postnatal period are decreasing with the transition from parenteral nutrition to enteral nutrition,indicating that the exogenous nutrition is relatively insufficient.C4-OH and C5 levels are negatively correlated with GA.In addition,lower level of C5-OH may indicate slow weight gain during the early postnatal period.
