Sudden infant death syndrome(SIDS) has become a highlighted topic in forensic medicine and pediatrics since it was firstly defined in 1969.As some great improvements were preceded in many aspects,people know more about its features,summarization,classification and related genes.There are many reports from developed areas such as North America,Europe,Australia,Japan etc.,but few from China.This review introduces SIDS's development history,new scientific findings and discusses the feasibility of further SIDS studies and the key points in forensic practice under the influence of San Diego definition of SIDS.

Objective To observe the effect and safety of Ginkgo biloba extract (EGb) in patients with chronic allograft nephropathy (CAN),and to study the clinical protective mechanism of EGb.Method A prospective,non-randomized,controlled study was conducted on 103 cases of CAN from March 2013 to March 2015.All patients were divided into experimental group (group A,53 cases) and control group (group B,50 cases).The group A was treated with EGb.Patients were followed up for at least 6 months.Before and after treatment,the changes in renal hemodynamic parameters were observed.The biochemical parameters were also observed,including 24-h urinary protein,urinary albumin,serum creatinine (Scr),triglyceride (TG),total cholesterol (TC),estimated glomerular filtration rate (eGFR),platelet count (PLT),fibrinogen (FIB),D-dimer (DD),activated partial thromboplastin time (APTT).The clinical efficacy and safety were analyzed.Result (1) Therewere no significant differences in clinical and biochemical parameters between the two groups before treatment (P＞0.05).(2) After treatment,the systolic peak flow velocity (Vmax) of segmental artery and arcuate artery in the experimental group was significantly higher than in the control group,and the resistance index (RI) in the experimental group was significantly lower than that in the control group,P＜0.05.(3) In both two groups,the 24-h urinary protein,urinaryalbumin,TG,TC and Scr were decreased after treatment (P＜0.05),and eGFR was elevated (P＜0.05).Moreover,the changes in 24-h urinary protein and urinary albumin in the experimental group were more significant than the control group after treatment (P＜0.05).(3) PLT,FIB and DD in experimental group were significantly decreased after treatment,and APTT was increased significantly (P＜0.05).PLT,FIB,DD and APTT had significant change after treatment in the experimental group as compared with control group.(4) There were no significant differences in adverse reactions between two groups (x2 =0.047,P =0.828).Conclusion The therapy of EGb in patients with CAN could reduce urinary protein and improve hypercoagulable state,and had few adverse reaction with good security.

Objective In recent years , SIT has gradually become the main way for the treatment of allergic rhinitis .To con-trast the clinical efficacy of specific immune therapy for one year and two years of allergic rhinitis and discuss the appropriate mainte -nance treatment time of subcutaneous immunotherapy with Dermatophagoides pteronyssinus . Methods Ninety-eight patients with al-lergic rhinitis to Dermatophagoides pteronyssinus were allocated to receive either treatment for one year (A group, n=46) or treatment for two years(B group, n=52).Nasal symptoms and medication scores of two groups were assessed to evaluate the clinical efficacy af -ter treatment respectively , and evaluate the quality of life of patients . Results There was no statistical significance in nasal symptom and medication scores between the two groups after one year treatment (7.00 ±1.08 vs 6.63 ±0.79, 1.50 ±0.51 vs 0.41 ±0.42, P>0.05).The quality of life in patients with decreased , but lack of statistical significance (345.00 ±31.89 vs 344.42 ±32.26, P>0.05).It presented statistical significance in nasal symptom and medication scores between the two groups after two years treatment (6.20 ±0.78 vs 4.29 ±0.64, 0.53 ±0.43 vs 0.21 ±0.34, P<0.05).The quality of life between patients also presented statistical significance (P<0.05). Conclusion Compared with A group, B group can significantly alleviate the symptoms of allergic rhinitis , so we think the optimal maintenance treatment time of specific immunotherapy for allergic rhinitis should be at least 2 years.

Parkinson's disease (PD) is a common neurodegenerative disorder associated with aging. Great progresses have been made toward understanding the pathogenesis over the past decades. It seems that both genetic factors and environmental factors contribute to PD, while the precise pathogenesis still remains unknown. Recently, increasing evidence has suggested that autophagy dysregulation is closely related to PD. Dysregulation of the autophagic pathways has been observed in the brains of PD patients or in animal models of PD, and a number of PD-associated proteins, such as a-synuclein, Parkin and PINK1, were found to involve in autophagy, suggesting a link between autophagy and pathogenesis of PD. In this review, we summarized the role of PD-associated proteins in autophagy pathways. In addition, we described the efficacy of autophagy-modulating compounds in PD models and discussed promising strategies for PD therapy.

Objective To investigate the immunological activity and the effect of an anti－ keratin monoclonal antibody 5G5 on the proliferation of serum－ free cultured keratinocytes. Methods The reactivity of 5G5 with cultured keratinocytes was observed by immunohistohemistry technique. The keratins extracted from the cultured keratinocytes was identified by SDS－ PAGE and their reactivities with 5G5 were assessed by immunoblot analysis. MTT was used to study the influences of 5G5 on the proliferation of cultured keratinocytes. Results 5G5 recognized the band of keratin with molecular weight of 50 000 only. Positive staining of 5G5 was found in the cytoplasm of cultured keratinocytes. The strong potential of 5G5 to inhibit the proliferation of cultured keratinocytes was shown by MTT assay with dose－ dependent manner. Conclusions The antibody which specifically recognizes the keratin with molecular weight of 50 000 may be the effective component to inhibit the proliferation of cultured keratinocytes.

Objective To investigate the clinical characteristics, diagnosis and treatment of acute intestinal perforation in the patients with colorectal carcinoma. Methods The clinical data of 38 colorectal carcinomas complicated with acute intestinal perforation treated in our hospital during 19 years were analyzed retrospectively. Results Acute intestinal perforation was common in old patients with colorectal carcinoma (mean age 62 years).The primary lesions were mostly located in left-side colon and superior rectum(27/38,71.1%). The perforation in the proximal colon of tumor and cecum accounted for 81.6%(31/38), and in tumor site accounted for 18.4%(7/38). The correct rate of preoperative diagnosis was only 15.8%(6/38). The postoperative complications were common and severe. The perioperative mortality was 42.1%(16/38). All the causes of death were multiple organ function deficiency. There were close relations between perioperative mortality and operation time. The postoperative recurrent rate was 41.2%(7/17). Five-year survival rate was 23.5%(4/17). Conclusion Early diagnosis, early operation and active prevention and treatment of multiple organ function deficiency were key to decrease the mortality of the colorectal carcinoma patients with acute intestinal perforation.

Objective To observe the effect of mivacurium,succinylcholine and atracurium in modified electric convulsive therapy (MECT).Methods Sixty ASA Ⅰ or Ⅱ patients with schizo-phrenia aged from 18 to 60 years old were randomly divided into 3 groups :mivacurium group (group A,n=20),succinylcholine group (group B,n=20),atracurium group (group C,n=20).The on-set time of muscle relaxation,the recovery time of spontaneous breathing after MECT,the awake time,as well as the changes of 5 min MAP,HR and SpO2 before and after MECT were observed re-spectively.Results The onset time of muscle relaxation and the recovery time of spontaneous breath-ing in group B were shorter than those in groups A and C (P <0.05).The onset time of muscle re-laxation and the recovery time of spontaneous breathing in group A were shorter than those in group C (P <0.05).Conclusion Mivacurium is a better alternative medicine in MECT in the situation of no succinylcholine or succnylcholine contraindication.
