OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92%) was higher than that of male patients (39.14%). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33%),skin and its appen-dants (411 cases,20.78%) and others (305 cases,15.42%). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46% of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.

Objective:To compare the clinical characteristics and prognosis of children with necrotizing pneumonia (NP) infected by bacteria and Mycoplasma pneumoniae (MP). Methods:The clinical data of 69 children with NP from January 2012 to June 2019 in Dalian Central Hospital Affiliated to Dalian Medical University were retrospectively analyzed. Among them, there were 27 cases of bacterial infection NP (bacterial infection group) and 42 cases of MP infection NP (MP group). The clinical symptoms and signs, extrapulmonary complications, laboratory examination, imaging examination, treatment, outcome and follow-up were compared between 2 groups.Results:There were no significant differences in the rale rate, respiratory tone reduction rate and total fever time between 2 groups ( P>0.05); the incidence of shortness of breath in bacterial infection group was significantly higher than that in MP group: 77.8% (21/27) vs. 14.3% (6/42), and there was statistical difference ( P<0.01). There were no significant differences in the incidence of extrapulmonary complications between 2 groups ( P>0.05). The white blood cell, C-reactive protein (CRP), procalcitonin (PCT) and interleukin (IL) -10 in bacterial infection group were significantly higher than those in MP group, the tumor necrosis factor (TNF)-α and interferon (IFN) -γ in bacterial infection group were significantly lower than those in the MP group, and there were statistical differences ( P<0.05). There were no significant differences in neutrophils, lactate dehydrogenase (LDH) and IL-6 between 2 groups ( P>0.05). The time of necrosis in bacterial infection group was significantly earlier than that in MP group: (14.5 ± 4.2) d vs. (21.7 ± 6.4) d, and there was statistical difference ( P<0.05); there was no significant difference in the incidence of pleural effusion between 2 groups ( P>0.05), but the incidence of pleural effusion separation in bacterial infection group was significantly higher than that in MP group: 70.4% (19/27) vs. 2.4% (1/42), and there was statistical difference ( P<0.01). There were no significant differences in antibiotic application time, CRP recovery time and hospital stay between 2 groups ( P>0.05); the oxygen uptake rate and closed thoracic drainage rate in bacterial infection group were significantly higher than those in MP group: 88.9% (24/27) vs. 35.7% (15/42) and 25.9% (7/27) vs. 11.9% (5/42), the recovery times of WBC and PCT in bacterial infection group were significantly longer than that in MP group: (12.8 ± 4.1) d vs. (9.2 ± 2.0) d and (10.5 ± 2.5) d vs. (7.6 ± 1.9) d, the bronchoalveolar lavage rate was significantly higher than that in MP group: 25.9% (7/27) vs. 76.2% (32/42), and there were statistical differences ( P<0.01 or <0.05). There was no significant difference in the absorption time of necrotic lesions between 2 groups ( P>0.05). Conclusions:Compared with MP infection, the clinical process of bacterial infection NP is serious, the necrosis time appears earlier, and the course of disease is longer. However, most of the children with NP can obtain a good prognosis after active symptomatic and antiinfective treatment.

OBJECTIVETo explore the effect of combined therapy of shenmai and compound danshen injection (SM-DS) on myocardial reperfusion injury after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).
METHODSThirty-eight AMI patients who received PCI were randomly divided into two groups, the 19 patients in the treated group were treated with SM-DS before and after PCI. Serum levels of malondialdehyde (MDA), superoxide dismutase (SOD), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) in patients' venous blood were measured at different time-points, and the integrated left ventricular ejection isometric index (Tei) was determined by echocardiogram.
RESULTSAs compared with before operation in the treated group, MDA was higher and SOD was lower at 2 hrs, 24 hrs after operation (P < 0.05); IL-6 and TNF-alpha were significantly lower at 24 hrs, 48 hrs and 1 week (P < 0.05, P < 0.01) and the Tei began to be improved at 24 hrs (P < 0.05) and significantly improved at 1 week after operation (P < 0.01). While in the control group, MDA was higher and SOD was obviously lower at 2 hrs and 24 hrs (P < 0.01); lowering of IL-6 and TNF-alpha appeared at 1 week (P < 0.05) and improving of Tei index revealed 1 week after operation respectively (P < 0.05). Comparison between the two groups showed significant difference in levels of MDA and SOD at 2 hrs and 24 hrs (P < 0.01); significant difference in levels of IL-6, TNF-alpha at 24 hrs, 48 hrs and 1 week; and in Tei index at 24 hrs and 1 week after operation (P <0.05).
CONCLUSIONSM-DS could reduce the myocardial reperfusion injury in patients with AMI after PCI.

Objective To study the conditions and methods of hydrodynamics-based transgene into rat regenerating liver in vivo. Methods The solution with concentration 30mg/L gene-containing plasmid was injected into rat tail veins at a speed of 2ml/s, then partial hepatectomy (PH) was performed at different times before/after injection, finally the rat (g) and regenerating liver (g) were weighed, and the liver coefficient (Lc) was calculated. Out of 15 groups which are Lc±Lc*0%, *5%, *10%, *15%, *20%, *25%, *30%, *35%, the most suitable group was chosen as correction coefficient to calculate the most appropriate volume of plasmid solution which was injected into the regenerating liver at different recovery times, and at the same time, right lobe of liver was gathered to make frozen section, then observe and quantify the positive green fluorescent protein (GFP) rate at 488 nm excitation wavelength. Results Injection of either physiological saline or empty plasmid has no significant difference compared with control (only PH performance). The appropriate time of hydrodynamics-based transgene is more than 12 hours before PH or anytime after PH. The solution volume of hydrodynamics-based transgene into liver regenerating rat after PH is rat weight (g) ×9%×1/3×corresponding correction coefficient (Trc). Both vector and target gene have effect on the time and abundance of gene expression. Conclusion Hydrodynamics-based transgene can effectively be applied to gene transfection in rat regenerating liver.

Objective:To analyze the effects of espO gene knockout on the biological characteristics of enterhemorrhagic Escherichia coli (EHEC). Methods:Two-step methods mediated by the suicide plasmid pCVD442-Δ espO and plasmid pTrc99a were used to construct the espO gene-deleted strain (Δ espO) and the complemented mutant (CΔ espO), respectively. HeLa cells were infected with different EHEC strains to analyze the biological functions and lethal effects of espO gene during infection. Results:PCR, electrophoresis and gene sequencing showed that the Δ espO and CΔ espO mutants were successfully constructed. Compared with the wild-type strain, neither the Δ espO nor CΔ espO mutant showed significant difference in growth rate, indicating that the espO gene had no influence on the growth and replication of EHEC. Furthermore, EspO could activate the tumor necrosis factor receptor (TNF)-induced NF-κB signaling pathway, while the effector protein NleB could inhibit the process. EspO could not inhibit the death of HeLa cells induced by TNF or TNF-related apoptosis-inducing ligand (TRAIL) after EHEC infection. Conclusions:In this study, we successfully constructed the espO gene-deleted and complemented mutants of EHEC and preliminarily analyzed the interaction between espO gene and host cells and the effects of espO gene on cell apoptosis during infection, which provided reference for further research on the in vitro biochemical activity and in vivo pathogenic roles of EspO.

Objective To analyze the effect of the changes of hospital diagnosis and treatment mode on the treatment time in patients with acute ischemic stroke before and after the establishment of Cerebrovascular Disease Center. Methods A total of 103 consecutive patients with acute ischemic stroke admitted to the Department of Neurology,Changhai Hospital,the Second Military Medical University between June 2008 and December 2012 were enrolled retrospectively. Thirty-one of them were excluded because of incomplete medical records. Finally,72 patients were enrolled as a control group and received series diagnosis and treatment mode. A total of 210 consecutive patients with acute ischemic stroke admitted to the Cerebrovascular Disease Center,Changhai Hospital,the Second Military Medical University from September 2013 to February 2015 were enrolled retrospectively. Thirteen patients were excluded (4 patients with recurrent transient ischemic attack were treated with recombinant tissue-type plasminogen activator,9 without complete data were treated with intravenous thrombolysis),197 were enrolled as an observation group finally,and they were received series diagnosis and treatment mode. The patients of both groups were visited within 4. 5 h after onset and received rt-PA treatment. The time-consuming changes of each time period from onset-to-door,door-to-imaging,imaging-to-needle,door-to-needle,and onset-to-needle time between the control group and the observation group were compared and analyzed. Results Compared with the control group,the door-to-imaging,imaging-to-needle,door-to-needle and onset-to-needle time were significantly shorter in the observation group. There were significant difference between the 2 groups (24 ± 12 min vs. 60 ± 20 min,27 ± 12 min vs. 62 ± 31 min,51 ± 17 min vs. 122 ± 52 min,and 153 ± 69 min vs. 230 ± 81 min,all P < 0. 01). There was no significant difference for onset-to-door time between the observation group and the control group (P > 0. 05). Conclusion The establishment of cerebral vascular disease center and the improvement of the processes have shortened the treatment time in patients with acute ischemic stroke within time window. The time from onset-to-door is still longer,and the propaganda and education of stroke should be strengthened.

Objective To study the effect of pioglitazone on the differentiation and function of rat osteoclast-like cells (OLC), and to probe the relationship between activated PPARγ2 and osteoclasts. Methods On day 1 of OLC formation from nonadherent bone marrow ceils (BMC) obtained from rats induced by M-CSF and receptor activator of NF-кB ligand (RANKL), 1, 5 and 10μmol/L pioglitazone hydrochloride was added. RT- PCR was performed to determine the mRNA expressions of PPARγ2 and receptor activator of NF-кB (RANK) on day 3, 5 and 7 during incubation, the number of tartrate-resistant acid phosphatase (TRAP)-positive cells,the number of bone resorption pits and the ratio of its area on dentin slice were counted, the activity of TRAP and the mean fluorescence intensity of integrin β3 (CD61) of OLC were also measured. Results (1) The effect on the differentiation of OLC: The addition of pioglitazone at the start of the culture period induced a dose-dependent decrease in TRAP-positive OLC and the activity of TRAP (P < 0.01 or P < 0.05) ; the mRNA expression of PPARγ2 was up-regulated by 5 and 10 μmol/L pioglitazone in the early stage of incubation and attenuated with thematuration of OLC on the contrary, however, the expression of RANK was down-regulated by 5 and 10 μmol/L piolitazone in every stage of incubation (P < 0.05 or P < 0.01), combined with decrease in TRAP-positive OLC from day 3 by 10 μmol/L pioglitazone. (2) The effect on the function of OLC: the number of bone resorption pits and the ratio of its area on dentin slice were decreased in groups of 5 and 10 μmol/L pioglitazone (P < 0.01 orP < 0.05), no obvious change was noted in the group with 1 μmol/L pioglitazone compared with the control group; the mean fluorescence intensity of CD61 were down-regulated in groups of 5 and 10 μmol/L pioglitazone (P < 0.05 or P <0.01). Conclusion Activation of PPARγ2 pathway by pioglitazone could partially inhibit differentiation and function of OLC derived from rat BMC.

OBJECTIVETo detect potential mutations for probands from families affected with Duchenne/Becker muscular dystrophy (DMD/BMD), and to carry out prenatal diagnosis through identification of female carriers.
METHODSA total of 43 DMD/BMD families were recruited. Multiplex PCR was used to analyze 18 exons within hotspots for DMD gene deletions. Multiplex ligation-dependent probe amplification (MLPA) was used to detect potential deletions and duplications of DMD gene for 43 patients and 36 females from 32 families. Prenatal diagnosis was performed for 27 families.
RESULTSDeletional mutations were detected in 26 patients with multiplex PCR. In addition, MLPA has detected 3 deletions and 6 duplicational mutations, and the ranges of mutations were all determined. Among 36 female members, 18 were determined as carriers of deletional mutations, 10 were excluded as mutation carriers. The status of remaining 8 could not be determined. For prenatal diagnosis, 3 out of 18 male fetuses were diagnosed as patients and 1 female fetus was identified as carrier.
CONCLUSIONMLPA is an accurate and reliable method for detecting deletional/duplicational mutations of DMD gene as well as for prenatal diagnosis and detection of female carriers.
