Source identification of human biological materials in crime scene plays an important role in reconstructing the crime process. Searching specific genetic markers to identify the source of different human biological materials is the emphasis and difficulty of the research work of legal medical experts in recent years. This paper reviews the genetic markers which are used for identifying the source of human biological materials and studied widely, such as DNA methylation, mRNA, microRNA, microflora and protein, etc. By comparing the principles and methods of source identification of human biological materials using different kinds of genetic markers, different source of human biological material owns suitable marker types and can be identified by detecting single genetic marker or combined multiple genetic markers. Though there is no uniform standard and method for identifying the source of human biological materials in forensic laboratories at present, the research and development of a series of mature and reliable methods for distinguishing different human biological materials play the role as forensic evi-dence which will be the future development direction.

Chlamydial infection in human urogenital tract induces inflammation and causes tissue damage and scarring. It is thought that cytokine production by the Chlamydia-infected cells plays a key role in chlamydial disease processes. Although many cytokines have been detected during chlamydial infection, little is known about the molecular mechanisms on how Chlamydia triggers and sustains the inflammatory cytokine cascades. In the current study, chlamydial infection of the human cervical epithelial cell line HeLa cells can induce the production of IL-8, IL-1α, IL-1β and IL-6. Using inhibitors for probing intracellular kinase signaling pathways required for the Chlamydia-induced cytokines, it was found that the Chlamydia-activated MAPK / P38 pathway is required for the chlamydial induction of IL-1α and IL-6 while both the Chlamydia-activated MAPK/ERK and MAPK/P38 pathways contribute to the production of IL-8.

Objective To evaluate the biomechanical effects of using a new injectable calcium phosphate cement to consolidate the fixation of osteoporotic intertrochanteric fracture.Method Five matchod pairs of human cadaver femora were used to produce the model of intertrochanteric fracture.All fractures were fixed with dynamic hip screws(DHS),and divided into two groups.In the CPC consolidation group of each pair,CPC was used to grout the hip screw and to fill the posteromedial defect.All femora were subjected to biomechanical test.Results Under the loading of 500 N,in the CPC consolidation group,the mean axial stiffness is(691.93±18.90)N/mm and the horizontal shear stiffness is(5553.84±27.47)N/mm.The mean lateral and medial strength is(5.15±0.35)MPa and(4.13±0.24)MPa.The torsion stiffness was 0.41 and the ultimate loading is(3580±286)N.In the control group,the mean axiak stiffness is(453.45±19.75)N/mm,the horizontal shear stiffness is(3848.87±22.63)N/mm,the mean lateral and medial strength is(3.12±0.37)MPa and(1.80±0.21)MPa,and,the torsion stiffness is 0.35 and the ultimate loading is(2512±189)N.Consolidation fixation with CPC increased each of the biomechanical efficiency(P＜0.05).Conclusions CPC consolidation of osteoprotic femoral head and the medial defect of intertrochanteric fracture can significantly improve the overall stability and decrease the rate of postoperative complication.

Objective:To determine whether chewing gum during the postoperative period facilitates the recovery of bowel function in patients after radical cystectomy with ileum urinary diversion.Methods:In the study,60 patients who underwent radical cystectomy followed by ileum urinary diversions during Nov.2014 and Nov.2015 in Department of Urology of Peking University First Hospital were randomized into three groups:gum chewing group,placebo group treated with the abdomen physical therapy machine and control group treated with ordinary method.Time to flatus,time to bowel movement,incidence of postoperative distension of the abdomen and abdominal pain,and gut related complications (such as ileus,intestinal fistula,and volrulus)of all the patients were recorded and analysed.Results:In gum chewing group,the median time to flatus was 57 hours (49 -72 hours),and the median time to bowel movement was 95 hours (88 -109 hours),which were significantly shortened compared with the other two groups of patients (82 hours,109 hours in placebo group and 81 hours,108 hours in control group, respectively).No significant difference of the median time to flatus and to bowel movement was observed between placebo group and control group.There were no significant differences in the incidence of post-operative distension of the abdomen and abdominal pain,and gut related complications among the three groups.Conclusion:Chewing gum had stimulatory effect on bowel function recovery after cystectomy fol-lowed by ileum urinary diversion.Chewing gum was safe and simple,and could be routinely used for postoperative treatment after cystectomy and ileum urinary diversion.

Objective: To explore the blood-saving effect of autologous platelet-rich plasma (PRP) back-transfusion in patients with Stanford type A aortic dissection surgery. Methods: A total of 59 consecutive patients who received Stanford type A aortic dissection surgery in our hospital from 2013-01 to 2015-10 were studied. The patients were at the age of (50±6) years with mean body weighting at (80±12) kg and were randomly divided into 2 groups: Traditional (T) group,n=31 and Autologous PRP back-transfusion (P) group,n=28. Blood levels of Hb, platelet counts, PT, APTT were measured at pre-induction of anesthesia (T1), before CPB (T2), prior ifnishing of CPB (T3) and at 1 h (T4), 24 h (T5), 48 h (T6) after the operation. The in-operative, 48 h post-operative volumes of allogeneic blood transfusion and the volume of chest tube drainage at 48h after operation were recorded; the complication occurrence at peri-operative period was recorded. Results: In P group, whole blood processing volume was (1269±197) ml, PRP volume was (753±78) ml, PRP separation time was (35±9) min and the separated platelets were about (22±3)% of total platelet counts. Compared with T group, P group had decreased Hb at T2 (131.0±15.0) g/L vs (101.0±10.0) g/L, decreased platelet counts at T3 (115.0±51.0)×109 /L vs (83.0±23.0)×109/L, while increased platelet counts at T4 (103.0±25.0)×109/L vs (151.0±27.0)×109/L, T5 (105.0±25.0)×109 /L vs (147.0±39.0)×109/L and T6 (101.0±26.0) ×109/L vs (149.0±35.0)×109/L, allP<0.05; P group presented reduced PT at T4 (17.6±2.1) s vs (14.1±1.1) s and T5 (17.6±2.7) s vs (13.5±0.8) s, allP<0.05. The in-operative transfusions of platelet, plasma, cold precipitation and post-operative transfusions of red blood cells, platelets, plasma, cold precipitation and the volume of chest tube drainage at 48h after operation were less in P group,P<0.05. Compared with T group, P group had the lower rates of acute post-operative lung injury (32.1% vs 19.4%), shorter mechanical ventilation time (69.1±5.9) h vs (43.1±1.5) h and ICU staying time (8.1±2.8) d vs (5.3±1.1) d, allP<0.05. Conclusion: Autologous PRP back-transfusion could reduce the post-operative bleeding and allogeneic blood transfusion for Stanford A aortic dissection surgery, it has obvious blood-saving effect.

Objective To summarize the preliminary experience and early -stage follow -up results of simple transesophageal echocardiography(TEE)to guide right jugular internal vein for closure of atrial septal defect (ASD), and to investigate its feasibility.Methods A total of 24 ASD patients(12 male,12 female)treated by transcatheter ASD closure under solely guidance of TEE were summarized in Children Heart Center,People′s Hospital of Zhengzhou University from February 2015 to February 2016.Mean age,body weight and average diameter of the 24 cases of ASD were 5 -18 (12.4 ±5.6)years old,16 -60 (34.1 ±9.6)kg,5 -20 (11.0 ±2.5)mm,respectively.All patients were treated by right jugular internal vein transcatheter closure under solely guidance of TEE.The efficiency of imme-diate post -operation under TEE was estimated,and follow -ups were done at 24 hours,1 month,3,6 and 12 months after the procedures by transthoracic echocardiography,X -ray examination and electrocardiogram.Results A total of 23 patients were treated successfully under solely guidance of TEE.The diameter of devices was (14.5 ±3.6)mm.The procedural time was(20.5 ±7.2)min.One patient who had 2 ASD was treated by traditional thoracic surgery,because the small ASD had 5 mm residual shunt after the procedures.There were 3 cases with trivial residual shunt after the pro-cedures immediately.All patients could move at once after operation.The average follow -up time was(5.6 ±1.2) months.No patients suffered from residual shunt,occluder malposition,peripheral vascular injury,pericardial effusion or cardiac perforation during the follow -up.Conclusions For some selected patients,simple TEE guiding right jugular in-ternal vein for closure of ASD is applicable.The method not only prevents injury from radiation,but also shortens the in -bed time and avoid the lower limbs braking,with good early -stage follow -up results are desirable.

OBJECTIVE:To provide reference for the development and improvement of pharmaceutical care in our hospital. METHODS:By questionnaire investigation,habits and understarding situation and demand of knowledge of drug use among pa-tients in our hospital were randomly collected by face-to-face interview or network platform. A statistical analysis was carried out on obtained results. RESULTS:In this questionnaire investigation,289 questionnaires were sent out face-to-face,and 282 valid ques-tionnaires were returned with effective feedback rate of 97.58%. Totally 51 valid questionnaires were returned through network plat-form. A total of 333 valid questionnaires were returned through two ways. The results of questionnaire investigation showed that 44.14% of the surveyed patients would read the drug instructions before taking drugs;41.14% of the surveyed patients would pay more attention to ADR and cautions stated in drug instructions. More than 60% of the surveyed patients had various bad habits of drug use. When getting better,66.07% of the surveyed patients would stop using drugs or reduce the dosage. When having not im-proved,26.73% of them would change drugs or increase dosage.Consulting with the medical staff was the most common source(69.07%)of drug use knowledge,and it was also the most trusted source(84.08%). Among the knowledge of drug use, surveyed patients most expected to understand theADR and side effects(65.46%),and the selectionindication and main us-er,cautions,drug interaction in multiple useandusage and dosagewere also selected frequently,and the choices of some options were significantly affected by the characteristics of people,such as age and education degree(P<0.05). The most expected way to acquire drug use knowledge wasface-to-face consultation with medical staff (72.97%),followed bytelephone consulta-tionandnetwork consultation,and the choices of some options were significantly affected by the characteristics of people,such as age and education (P<0.05). CONCLUSIONS:Patients in our hospital haven't pay enough attention to drug instructions and their content,and bad habits of drug use still exist. Sources of drug use knowledge are diverse,but confidence of other sources is not enough except for source of medical staff. The demands for the knowledge of drug use are different,however,the present form and content of pharmaceutical care in our hospital cannot fully meet the needs of patients.
