Objective To investigate the feasibility of DNA sequencing analysis in molecular diagnosis for spinal muscular atrophy (SMA). Methods Two pairs of primers were utilized to amplify the region including 5 different bases in SMA-causative gene SMN1 and its homologue copy SMN2 by polymerase chain reaction (PCR). The first primer amplified a fragment 501 bp long spanning from SMN intron 6 to intron 7 targeting four different bases (g.31957, 32006, 32154 and 32269). The second primer reversely amplified a 189 bp long fragment within SMN exon 8 including one base-pair differ-ence (g.32734). PCR procedure was followed by Sanger sequencing technique to identify the 5 different bases. SMA patients caused by SMN1 homozygous deletion were distinguished from carriers or normal controls by absence of SMN1 specific bas-es in sequence chromatograms. This assay was performed in 7 SMA suspected patients and their parents. The specimens were also detected by PCR- restriction fragment length polymorphism (RFLP) method. Results It was found that 6 of 7 SMA suspected patients showed only SMN2 specific bases at the 5 different base positions among the region from intron 6 to exon 8, which meant the patient displaying only SMN2-specific nucleotide a, T, g, g and A at g.31957, 32006, 32154, 32269 and 32734, while their parents (carriers) showed a/g, T/C, g/a, g/a and A/G at the same sites. SMN1 gene was deleted in the patient, and the deletion region was inferred from intron 6 to exon 8. Because carriers had both SMN1 and SMN2 genes, they can be discriminated from the SMN1 deleted patient. One of 7 patients yield an unique sequence chromatogram of a, T, g, g and A/G, indicating that exon 8 of SMN1 was not deleted in this patient. Conclusion DNA sequencing analysis is an alter-native simple method for detecting SMA caused by homozygous deletion of SMN1. We recommend to replace the widely used PCR-RFLP method with DNA sequencing assay.

Objective To sum up the characteristics of hemorrhagic fever with renal syndrome(HFRS)and acute pancreatitis,to improve the understanding of the cases of atypical HFRS,reduce the misdiagnosis rate and improve the cure rate.Methods 3 cases of HFRS complicated with acute pancreatitis in our hospital from 2011 to 2015 were retrospectively analyzed.Results 3 cases were middle -aged men,with an average age of 46.6,of which two cases occurred in Huangling county in the city,the remaining 1 case occurred in Yichuan county of the city. Occupation was the railway workers,drivers,farmers.Respectively occurred in February,July,December.3 cases of blood routine,urine routine,blood coagulation performance were consistent performance for RBC,WBC,PLT decrease;hematuria,proteinuria;3 cases of plasma amylase were higher than that of more than 3 times the normal value,the serum lipase was higher than the more than 3 times the normal value;hemorrhagic fever antibodies were positive;treatment of 2 cases with hemodialysis treatment,1 case underwent intestinal dialysis treatment,successful treatment of all.Conclusion HFRS with acute pancreatitis patients were less,easy to be misdiagnosed or ignored,easy illness of incur loss through delay and once with acute pancreatitis will add to the original condition,treatment more difficult tend to have higher mortality rate.It should be according to the clinical manifestations,early blood and urine amylase, abdominal B ultrasound and CT examinations of the abdomen as soon as possible,to improve the accuracy of diagnosis, take appropriate treatment measures,especially blood dialysis treatment,can reduce the mortality rate.

Placenta implantation is a rare but dangerous postpartum complication. In this study, 17 cases of placenta implantation were allocated to two groups. The treatment group?(9?cases)was treated with modified Xuefu Zhuyu Decoction on the basis of intravenous drip of methotrexate. The control group(8?cases)was treated with intravenous drip of methotrexate combined with oxytocin and antibiotic. The results showed that all of the cases in the treatment group were cured and no one case received uterine curettage or uterectomy.But in the control group,5 received uterine curettage and 1 total uterectomy. It is indicated that Chinese herbal medicine combined with western medicine is a better therapy for placenta implantation.

Objective To investigate the clinical characteristics, pathological features and surgical indications of polypoid lesions of the gallbladder (PLG). Methods The clinical data of 267 patients with PLG confirmed by pathological examination were analyzed retrospectively. Results PLG was found more frequently in young and middle-aged people. Of the 267 patients, 166 were male and 101female. There were 241 cases with cholesterol polyps(CPs) (90. 3%). CPs were the most common PLG, but they presented no special clinical features. Conclusion CPs are dominant in PLG. Patients older than 60 years with a single polyp lesion or gallbladder stone complications should resort to surgical treatment. Patients with no symptoms and PLG of less than 10mm should be followed up periodically. Cholecystectomy for PLG should be performed based on strict indications of PLG.

Tyrosinase is a key enzyme related to skin pigmentation disorders of elderly people, while self-aggregation of the amyloid-beta peptide, Abeta42, has been considered as a key event in the pathogenesis of Alzheimer's disease (AD). The present study was undertaken to investigate the inhibitory effects of 20 samples from Rhodiola species on tyrosinase and Abeta42 aggregation, and to isolate their corresponding bioactive components. The results demonstrated that the oligomeric proanthocyanidins (OPCs) commonly found in Rhodiola species were the major bioactive components corresponding to their anti-tyrosinase and anti-Abeta42 aggregation bioactivities. Salidroside, a representative compound of Rhodiola plants, proved not to be active in the present studies.

Objective To investigate the clinical characteristics and the causative mechanism of acetabular fracture and dislocation of hip complicated with sciatic nerve injuries. Methods A retrospective analysis was done for 155 cases (159 sides) of acetabular fracture, dislocation of hip, or acetabular fracture combined with hip dislocation, 35 of which were complicated with sciatic nerve injuries. The epidemiological features of acetabular fracture and hip dislocation, the incidence, and relationship between sciatic nerve injury and classifications of acetabular fracture and dislocation of hip were analyzed. Results 81.3%of the patients were male. The ages of 86.5%of the patients ranged from 20 to 50 years old. 83.9%of the cases were injured in traffic accidents. The incidence of sciatic nerve injury was 22.01%in all the patients, 17.19%in patients with acetabular fracture, 12.90%in patients with posterior wall, and 36.36%in patients with acetabular fracture combined with posterior dislocation of hip. Conclusions A road traffic accident is the major causative factor for acetabular fracture and dislocation of hip. Most victims are male. Sciatic nerve injuries largely happen in cases of acetabular posterior wall fracture and posterior column fractures combined with posterior dislocation of hip. Peroneal nerve injuries are the most common type of sciatic nerve injury.

Angiogenesis is of great importance to a variety of normal physiological processes and pathological disorders.It is tightly regulated by many mechanisms, among which vascular endothelial growth factor(VEGF) is one of the most potent promoters.VEGF binds and activates its specific receptor tyrosine kinases, especially vascular endothelial growth factor receptor-2(VEGFR-2).VEGFR-2 mediates the key functional and biochemical effects of VEGF in endothelial cells including proliferation, migration, survival, and permeability.Following its binding to VEGF, VEGFR-2 dimerizes and undergoes autophosphorylation on tyrosine residues within its cytoplasmic portion.This creates docking sites for adapter molecules to be recruited through their Src homology domain-2(SH2).These adapter molecules can then initiate the activation of downstream signaling cascades.Further down-stream effector molecules are activated, and regulate the biological effects of endothelial cells.It is also foound that VEGF/VEGFR-2 signaling pathway may negatively regulate the function of human monocyte-derived mature dendritic cells(DCs) as well as the maturation of immature-DCs.Advances in the understanding of the VEGF/VEGFR-2 signaling pathway may contribute to the discovery of kinds of pharmaceutical agents.

Objective To study the difference on knowledge-attitude-practice about rational drug use in tumor patients between urban and rural in Shanxi province, and to provide evidence for further development on health education of rational drug use. Methods A questionnaire investigation was conducted among tumor inpatients in Shanxi Cancer Hospital from May 22 in 2014 to May 30 in 2014. Results A total of 990 tumor patients were involved, including 499 urban patients accounting for 50.4 % and 491 rural patients accounting for 49.6 %. The tumor patients′awareness rates of 'the purchase of antibiotics needs a prescription' in urban and rural areas were the highest, 74.9 % (374/499) and 67.0 % (329/491), respectively, and the awareness rates of 'the meaning of OTC on the medicine package' were the lowest, 22.0 % (110/499) and 18.1 % (89/491), respectively. 96.2%(480/499) urban and 92.7%(455/491) rural tumor patients had developed a correct attitude towards 'irrational drug use will affect health and even life-threatening' which ranked the highest, and the rates of correct attitude towards 'adverse drug reaction is the medical accident' were the lowest, 55.5 %(277/499) and 48.1 % (236/491), respectively. The correct behavior rates of 'read the drug instructions' in urban and rural tumor patients were the highest, 97.8% (488/499) and 95.1 % (467/491), respectively, and the correct behavior rates of 'the expired drug recovery to nearby regular pharmacy' were the lowest, 9.2 %(46/499) and 7.5 % (37/491), respectively. Conclusions The knowledge-attitude-practice about rational drug among urban and rural tumor patients in Shanxi province is not optimistic. It should be provided that individual health education in daily work in order to promote rational drug use, prolong survival time and improve the quality of life for tumor patients.
