A method of typing of EsD-PCM_1-CLOI on the same gel electrophoresis has been devel- oped by improving and mixing the individual tests of typing EsD, PGM_1and GLOI. The method supplies a reliable, economical and practical means for more wide-spread use of EsD, PGM_1 and GLOI in the forensic medicine field.

Objective To study the effect of electroacupuncture(EA) combined with transcranial magnetic stimulation(TMS) on the angiogenesis in rats with cerebral ischemia. Methods Fifty-five male Wistar rats were randomly divided into five groups: a normal group, a model group, an EA group, a TMS group and an EA plus TMS group. After the establishment of acute middle cerebral artery occlusion (MCAO), the rats in various groups were accordingly treated with EA, TMS or EA plus TMS, respectively. Then the expression of VEGF164 mRNA and CD31 was observed. Results The expression of VEGF164 mRNA and CD31 around the infarction locus of the three treatment groups increased, especially in the EA plus TMS group. Conclusion EA plus TMS can increase the expression of VEGF164 mRNA and CD31 around the infarction locus and promote the non-molecular angiogenesis in rats with cerebral ischemia.

Objective To analyse clinical and imaging characteristics of congenital airway abnormalities,and to guide the clinical diagnosis and reduce rate of missed diagnosis and misdiagnosis.Methods Clinical and imaging characteristics in children who had been diagnosed congenital airway abnormalities in Shengjing Hospital of China Medical University from 2005 to 2011 were reviewed and analysed retrospectively.Results Of 23 children,12 cases were male,11 cases were female,the age was from 1 month to 10 years,the average age was 32 months.The disease course was from 3 days to 3 months,an average was 18 days.Clinical manifestations were repeated coughing,wheezing,dyspnea and recurrent respiratory infection.Through the spiral CT and three dimensional reconstruction,enhanced CT examination,6 cases of tracheobronchial stenosis,3 cases of trachea and bronchus,1 case of dysplasia of the left pulmonary artery and vein,3 cases of pulmonary sequestration,4 cases of pulmonary cyst and 6 cases of pulmonary hypoplasia were found.Conclusion Missed diagnosis and misdiagnosis of congenital airway malformations often occurs.When the following features were observed,congenital airway malformations may be taken into account:persistent cough; repeated or persistent wheezing,treated ineffectively with anti-inflammatory agent and bronchodilators ; recurrent or persistent stridor; repeated pulmonary infections,dyspnea; repeated or persistent pneumonia in the same part and unexplainedly mediastinal shift in X ray chest radiography.Spiral CT three dimensional reconstruction and enhancement is of great value in diagnosis of airway malformation.

Post-infectious bronchiolitis obliterans(PIBO) is a rare serious chronic lung disease characterized by irreversible small airway fibrosis.Lower respiratory infections are the most common causes in children.Its major clinical characteristics are recurrent or persistent cough, wheezing, shortness of breath, hypoxia, crackles, and persistent for above 6 weeks.Clinical diagnosis mainly depends on clinical manifestations, lung function and high-resolution CT examination.At present, there is no unified standard of treatment, mainly empirical treatment.Most of the children have a poor prognosis, and a small number of children can achieve good results through early diagnosis and intervention.

Objective To study the role of glutamate receptor subtypes in nucleus tractus solitarius(NTS)in cardiac-somatic motor reflex (CMR)induced by intrapericardial administration of capsaicin,and to clarify the modulation mechanism of NTS to cardiac nociceptoion.Methods 60 SD rats were randomly divided into ibotenic (IBO)group, glutamate group, MK-801 group, MCGP group, MK-801 + MCPG group and DNQX group. The NTS microinjected with 130 mmol·L-1 IBO 100 nL,100,200,500 mmol·L-1 L-glutamate 100 nL,NMDA receptor antagonist 40 and 60 mmol · L-1 MK-801 100 nL, metabotropic glutamate receptors antagonist 25 and 50 mmol·L-1 MCPG 100 nL,25 mmol· L-1 MCPG 50 nL plus 40 mmol· L-1 MK-801 50 nL,non-NMDA receptor antagonist 20 and 50 mmol·L-1 DNQX 100 nL,respectively.The changes of CMR of the rats in various groups were observed.Results Compared with control group,the CMR of the rats in IBO group was decreased (P<0.05);the CMR was increased as the concentration increased in glutamate group(P<0.05);the CMR in MK-801 and MCPG groups were decreased (P<0.05);the CMR in MK-801+MCPG group was decreased (P<0.05);the CMR in DXQX group had no changes (P>0.05).Conclusion NTS play an facilictory role in cardiac nociception,and the NMDA receptors and mGluRs receptors mediate this facilitory modulation.

Objective To explore the role of metabotropic glutamate receptors (mGluRs)group Ⅲ and its subtypes mGluR7 and mGluR8 in nucleus tractus solitarius(NTS)in cardiac-somatic motor reflex (CMR),and to clarify the modulation role of mGluR Ⅲ and its subtypes in NTS in cardiac nociceptoion.Methods 40 SD rats were randomly divided into L-AP4 group,microinjection of mGluRs Ⅲ agonist L-AP4 0.1,1.0,10.0 or 20.0 nmol in NTS;AMN082 group,microinjection of mGluR7 agonist AMN082 1,2 or 4 nmol;DCPG group,microinjection of mGluR8 agonist DCPG 4, 6 or 8 nmol;MSOP group, microinjection of mGluR Ⅲ antagonist MSOP 20 or 100 nmol,20 nmol MSOP+410 nmol L-AP,20 nmol MSOP+2 nmol AMN082,20 nmol MSOP+6 nmol DCPG. The changes of CMR of the rats in various groups were observed.Results Compared with control,the CMR in L-AP4 and AMN082 groups was decreased (P<0.05);the CMR in DCPG group was increased (P<0.05);the CMR in MSOP group after injection of 20 nmol MSOP had no change (P>0.05);the CMR in MSOP group after injection of 100 nmol MSOP was increased (P<0.05);the CMR in MSOP group after injection of 20 nmol MSOP followed L-AP4 or AMNO82 had no change (P>0.05).Conclusion The group Ⅲ mGluRs in the NTS play an inhibitory role in cardiac nociception, and mGluR7 has anti-nociceptive effects while mGluR8 has pro-nociceptive effects.

Tachycardia-induced cardiomyopathy (TIC) is defined as a kind of cardiomyopathy with cardiac dilatation and dysfunction secondary to sustained or recurrent tachyarrhythmia.Myocardial dysfunction can wholly or partially recover after control of the responsible tachyarrhythmia.TIC,a reversible acquired cardiomyopathy with generally benign prognosis,can occur at any age;however,it often proves to be unrecognized by most of pediatricians in clinical practices.Now,the clinical criteria,pathogenesis,characteristics,therapy and prognosis of pediatric TIC were summarized,so as to provide a clinical basis for early recognition and prompt therapy.

Objective To investigate the clinical features of X-linked agammaglobulinemia (XLA)in children,and to improve the early diagnostic rate.Methods The medical records of 11 children with XLA between Dec 2003 and Nov 2011 were reviewed.Results The smallest age of 11 cases with XLA presenting the first symptoms was 0.4 years old and the oldest age was 4 years old with a mean of 2.4 years old.The first diagnosis time was at the age of 3.5 to 13 years old,with a mean of 7 years old.The age at first diagnosis in 63.6％ ( 7/11 ) of patients was more than 7 years old.Two patients ( 18.2％ ) had the family history of the similar disease.Two patients were died from the infection and 1 patient was missed.The other 8 patients were survived.Respiratory infections occurred in 100％ of the 11 patients.54.5％ (6/11 )of the patients were suffered with otitis media and digestive infections were seen in 36.4％ (4/11 ) of the patients.The levels of lgA,IgM and IgG in the serum of the pauents were all decreased.The levels of IgG in the serum of 9 patients were less than 2 g/L and in the serum of the other 2 patients were less than 2.4 g/L.The levels of CD19 in the serum were all less than 1％ and an inversed ratio of CD4/CD8 was observed in 9 patients.Eight patients were diagnosed as XLA by gene detection.Conclusion The age presenting first symptoms in children with XLA in this study is earlier than the reported data and the age at first diagnosis is later.Respiratory infection is the most common manifestation.High prevalence of otitis media and digestive infections are common.The patients with XLA rarely have the family history.The early diagosis and long-term treatment with the intravenous immunoglobulin may improve the prognosis of XLA.

Objective To observe the clinical effect of modified B-lynch suture in the treatment of patients with pernicious placenta pre-via.Methods A total of 46 patients with pernicious placenta previa in our hospital were randomly divided into the modified B-lynch suture treatment group(modified group)and the conventional therapy group(convention group),with 23 cases in each group.The operation time, menstrual recovery time and lochia sanguinea time,postpartum hemorrhage,intraoperative blood soss,abnormal temperature time,placenta ac-creta,hysterectomy and neonatal asphyxia between the two groups were compared.Results The intraoperative blood soss and postpartum hemorrhage of modified group was less than those of convention group,the menstrual recovery time was shorter than that of convention group and the rate of resection of uterine was lower than that of conventional group,with significant difference (P <0.05).There was no statistically significant difference in operation time,abnormal temperature time,lochia sanguinea time,placenta accreta and neonatal asphyxia between two groups (P >0.05).Conclusion The clinical effect of modified B-lynch suture in the treatment of dangerous placenta previa is significant.
