Objective To investigate the relationship between the polymorphisms of collagen type Ⅰ alpha 1 (COLIA1) gene and bone mineral density of postmenopausal women in Shanghai. Methods The polymorphisms of Sp1 binding site in COLIA1 gene were observed in 205 postmenopausal women by PCR, digested with MscⅠ restriction endonuclease and separated by 12% polyacrylamide gel electrophoresis. The capital letter S represents for the absence of the restriction endonuclease site, while the small letter s for the presence of the restriction endonuclease site. Bone mineral density at lumbar spine and femoral neck, etc. were measured by DEXA. Results Neither Ss nor ss genotypes of COLIA1 gene was found in our sample, all were SS genotype. Conclusion The contribution of Sp1 site variation of COLIA1 gene to bone mass might have a strong ethnic difference. The restriction fragment length polymorphisms of COLIA1 gene do not show relationship with the bone mass of postmenopausal women in Shanghai. The significance of this genetic marker of osteoporosis needs to be further explored in larger samples and in different areas.

20?10 9/L on day 16 (range 9~35).Over grade Ⅱ acute GVHD occurred in three patients(25%) and chronic GVHD occurred in five patients, including three patients with localized chronic GVHD and two with extensive chronic GVHD . The incidence of acute GVHD in allo-PBSCT is similar to allo-BMT, while care should be taken for the occurrence of chronic GVHD.

Myocardial ischemia/reperfusion(MI/R) injury refers to restoring blood perfusion after myocardial ischemia for a relatively long time, but the tissue appears more obvious and severe myocardial damage and dysfunction than before reperfusion, this phenomenon mainly relates to inflammation, oxidative stress, cell apoptosis, cell autophagy and so on.NF-κB is a nuclear transcription factor involved in regulating a variety of pathophysiological processes, which also plays an important role in all aspects of MI/R injury.The in-depth study of NF-κB in MI/R injury and clinical application of related research will provide new ideas and methods for treating MI/R injury.

Objective To investigate the effect of valsartan and amlodipine on urinary microalbumin in elderly hypertensive patients. Methods 100 elderly patients with hypertension treated in our hospital from May 2015 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group received oral valsartan, and the patients in the experimental group were treated with valsartan and amlodipine. The treatment time of the experimental group and the control group was 12 weeks. The clinical indexes of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the experimental group and the control group did not have obvious adverse reactions. There were 2 cases of headache in the experimental group, 1 cases of vertigo, and 2 cases of vertigo in the control group. However, there was no significant difference in the incidence of adverse reactions between the experimental group and the control group, and there was no statistical significance. The antihypertensive effect of the experimental group was significantly higher than that of the control group, with statistical significance (P<0.05). After treatment, the urinary microalbumin in the experimental group and the control group was significantly lower than that in the treatment group, and the level of microalbuminuria in the experimental group was lower than that in the control group, with statistical significance (P<0.05). Conclusion The clinical effect of treatment of elderly patients with hypertension better combined with valsartan and amlodipine, antihypertensive effect is stronger, can significantly improve the patient's urinary albumin, with further clinical promotion and application significance.

Objective To study the protective effect of the hypothermic brain-protection apparatus on hemorrhagic shock rabbits. Methods Applying the modified Wigger's shock animal model, we observed the effects of a self-developed brain-protecting apparatus on the survival time and vital signs of rabbits. Results Hypothermic brain protection could considerably reduce 60% lipid hyperoxide in brain tissues as compared with that in the control group. It could also decrease heart rate and respiration and hence reduce tissue oxygen consumption. Conclusion Hypothermic brain protection can attenuate the brain lesion and obviously prolong the survival time of hemorrhagic shock animals.

To analyze the outcome of allogeneic peripheral blood stem cell transplantation(allo PBSCT) for hematological malignancies and prevention of complications, forty one patients with hematological malignancies were treated with allo PBSCT. One regimen of prophylaxis for acute graft versus host disease(GVHD) was the combination of cyclosporine(CsA)and methotrexate(MTX),another mycophenolate mofetil(MMF) with cyclosporine and methotrexate .The results showed that all patients were successfully engrafted .The incidence of over grade Ⅱ acute GVHD after HLA matched transplantation was 21 05%(8/38). Chronic GVHD occurred in 19/25(76%) patients. Three of thirty four patients with acute leukemia(CR 1 ) and CML(CP) after HLA matched transplantation relapsed(8 82%). The disease free survival was 71 43%(10/14) after follow up for more than 2 years. The results suggest that the incidence of acute GVHD in allo PBSCT appears to be similar to allo BMT, but the incidence of chronic GVHD in allo PBSCT is higher than that in allo BMT. Infection and interstitial pneumonitis are the main cause of death.

Objective To explore the relationship between the expression of LIGHT/HVEM in patients after allo-HSCT and the development of GVHD. Methods The expression of LIGHT and HVEM in T lymphocytes was detected by FACS Calibur. Results All patients achieved engraftment and hematopoiesis reconstitution, aGVHD occurred in 9 of 26 patients (34.6%) with grade Ⅲ-Ⅳ aGVHD in 3 cases. Seven cases developed cGVHD (26.9%). LIGHT was not expressed in T lymphocytes from healthy donors and patients without GVHD, while constitutive expression of HVEM was detected. When aGVHD occurred, the expression levels of LIGHT in T lymphocytes were significantly increased, while those of HVEM decreased. After GVHD was controlled, the expression levels of those co-stimulators went back to normal On the day 15 after transplantation, the expression of LIGHT in T lymphocytes of patients with aGVHD later was significantly higher, while that of HVEM lower than in those without aGVHD. The patients with aGVHD of grades Ⅲ-Ⅳ demonstrated higher LIGHT expression than in those with aGVHD of grades Ⅰ-Ⅱ. Conclusion The expression of LIGHT and HVEM might be involved in the development of GVHD after allo-HSCT and could be used as one of the useful indicators in predicting aGVHD.

Objective To investigate the characteristics of pathogenesis and therapeutics of myelodysplastic syndrome(MDS)and aplastic anemia(AA)combined with autoimmune disease(AID).Methods Retrospective analysis and follow-up visit of 111 patients with MDS and 56 patients with AA in our hospital were studied.Results There were 9(8.1%)of 111 patients with MDS and 2 (3.6%)of 55 patients with AA coexistent with AID.Autoimmune hemolytic anemia(36.4%)and Behcet Disease(18.2%)were common among those combined with AID.5 patients had AID proceeding to the occurrence of MDS/AA.4 patients had simultaneous occurrence of AID and MDS/AA.2 patients developed AID three years later after the diagnosis of MDS.Conclusion There was a certain intrinsic relationship between MDS/AA and AID.

BACKGROUND: The most dangerous consequence of thoracolumbar burst fracture is its neurological deficits(caused by primary and/or secondary injury) . It is reported that posterior spinal decompression combined with internal fixation are viable in reduction of fracture and indirect decompression of obstructed spinal canal.OBJECTIVE: To evaluate the effect of anterior decompression combined with STRYKER thoracoluambar anterior internal fixation system in improving spinal canal stenosis and spinal mechanical axis in thoracolumbar burst fracture.DESIGN:It is a case report.SETTING:An orthopedic department of a municipal hospital.PARTICIPANTS:In this study, five patients (four male, one female, aged 17 - 34 years) were recruited who suffered from thoracolumbar burst fracture and spinal cord dysfunction and were treated in the Orthopaedic Departnent of Dongguan Taiping People' s Hospital from September 2001 to February 2002.METHODS: All patients received anterior decompression and intervertebral grafting with iliac or rib bone flap combined with reduction and internal fixation by STRYKER system. X-rays of thoracolumbar vertebrae were taken in the 1st, 3rd, 5th and 9th post-operative months for observation of fusion of injured segments, improvement of narrowed spinal canal and kyphosis angle. And Frankel scale was adopted for evaluation of the patients during follow-up(A for bad and E for excellent).narrowed spinal canal.RESULTS: All of the 5 patients entered analytic stage and follow-up lasted grade B in one patient, all the others got Frankel grade E and could walk gical operation was 68.9% and after operation there was no spinal canal tion to 0° - 6° afterward.CONCLUSION: Anterior spinal decompression can directly and completely provide satisfactory environment for the recovery of neurological of deficits spinal cord. STRYKER thoracoluambar anterior internal fixation system applied in patients with thoracolumbar burst fracture and paraplegia can effectively restore normal spinal curve with the advantages of simple procedure and stable fixation as well as the characteristics of biological internal fixation such as satisfactory reduction and stable fixation.

Objective To improve the recognition for infantile spinal muscular atrophy (SMA-Ⅰ) and the level of early diagnosis,intervention and treatment for SMA-Ⅰ.Methods The clinical data of 39 patients with SMA-Ⅰ were analyzed retrospectively, including the clinical manifestations, neural electrophysiological characteristics, geno-type, diagnosis,treatment and prognosis of SMA-Ⅰ.Results Of the 39 cases with SMA-Ⅰ , 37 cases (94.9％) had onset in 6 months after birth.The paralyses of the limbs were symmetrical and flaccid.The lower was more severe than the upper , and the proximal was more severe than the distal, hypotonia and tendinous reflex disappears.Thirty-two cases (82.1％) had normal serum creatine kinase, and 7 cases (17.9％) increased slightly.Nerve electrophysiological examination showed that 169 (96.0％) had spontaneous potentials in 176 muscles.Of 160 limb muscles,35 (21.8％) released few motor unit potential (MUP) ,117 (73.1％) extended the duration of MUP and 104 (65.0％) increased the amplitude of M UP.Of 167 peripheral motor nerves, 160 (95.8％)decreased the amplitude of the compound muscle action potential and 162 (97.0％) had normal motor conduction velocity.Of 93 peripheral sensory nerves, 93 (100.0％) had normal range of the conduction.The gene detection showed that 38 cases had homozygous deletion of exon 7,8, and 1 case had homozygous deletion of exon 7 and heterozygous deletion of exon 8.In the effective follow-up of 30 cases,6 cases died in the 2-3 months after birth,4 cases died in 10 months after birth, 12 cases died in 12-18 months after birth.Six cases survived to 2 years old,2 cases survived to 3 years old,and all of them died of pulmonary infection.Conclusions There are typical clinical and nerve electrophysiological characteristics for SMA-I.Nerve electrophysiological examination can be used as an important method for diagnosis and differential diagnosis for SMA-I.Genetic testing can be used to identify the disease and make prenatal diagnosis.Through comprehensive intervention the quality of life can be improved in SMA-Ⅰ children.
