Objective To census the preoperative prevalence rate of deep venous thrombosis (DVT) and to evaluate the risk factors of DVT in senile osteoporotic hip fractured patients.Methods The object of study were patients aged 60 and above, and osteoporotic hip fracture by low energy injury in 2013.Based on medical records, all the patients with osteoporotic hip fracture were evaluated the signs and symptoms of DVT in 24 h, D-dimer test and underwent Doppler ultrasound screening of bilateral venous system in lower extremity after admission, and all the patients received preoperative prophylactic anticoagulation.Patients with popliteal and proximal level thrombus or floating thrombus underwent inferior vena cava (IVC) filter insertion.Outcome measures: age, gender, fracture type, D-dimer value in 24 h preoperatively, occurrence time of DVT and region, grade of preoperative American Society of Anesthesiologists, preoperative medical diseases.Results 702 of 946 hip fracture inpatients were comprised in this retrospective study.All were not founded any symptom or signs of DVT.All patients were took preoperative Doppler ultrasound screening and the results as follows: 36 of 302 patients (11.9％) with femoral neck fracture were proved preoperative thrombosis(13 male, 23 female), the average age was 72.7 year-old(range from 62-90 year-old), on the same side as the fractured hip in 31 patients, bilateral thrombosis in 5 patients.74 of 400 patients (18.5％) with intertrochanteric fracture were proved preoperative thrombosis(38 male, 36 female), the average age was 76 year-old (range from 60-95 year-old), on the same side as the fractured hip in 68 patients, bilateral thrombosis in 6 patients.The most prevalence rate of DVT were in the first day after osteoporotic hip fracture, 15 patients (41.7％) with femoral neck fracture and 38 patients (51.40％) with intertrochanteric fracture.There were more proximal level and multiple level involment thrombosis over 5 days after injury.The most thrombosis were proven at calf and popliteal vein.Conclusion The prophylaxis of DVT should be started even in the emergency department in senile patient with osteoporotic hip fracture.To avoid the risk factors, early surgery and early postoperative mobilization will be effective.

OBJECTIVETo investigate the correlations of 24 biochemical markers in the seminal plasma with routine semen parameters.

METHODSAccording to the WHO5 standards, we analyzed the routine semen parameters of 66 subfertile men, including the semen volume, sperm concentration, total sperm count, sperm motility, and the percentage of progressively motile sperm (PR). Based on the calibration and quality control measures and using an automatic biochemistry analyzer or electrolyte analyzer, we detected 24 biochemical markers in the seminal plasma of the patients, including total protein (TP), albumin (Alb), globulin (Glb), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), γ-glutamyltransferase (GGT), lactate dehydrogenase (LDH), creatine kinase (CK), alpha hydroxybutyrate dehydrogenase (αHBDH), adenosine deaminase (ADA), glucose (Glu), triglyeride (TG), total cholesterol (TC), urea nitrogen (UN), creatinine (Cr), high-sensitive C-reactive protein (hsCRP), K+, Na+, Cl- , Ca, Mg, and phosphorus (P). Then we analyzed the correlations of the 24 biochemical markers with routine semen parameters.

RESULTSThe levels of the TP, Alb, and Glb proteins in the seminal plasma were positively correlated with sperm concentration, so was that of Alb with the total sperm count, and the AST and LDH activities with sperm concentration and total sperm count. The AKP activity in the seminal plasma was correlated negatively with the semen volume, but positively with sperm motility. The αHBDH activity exhibited a positive correlation with both sperm concentration and total sperm count, with a coefficient of correlation (r) above 0.7. The UN level was correlated negatively with the semen volume, so was the Cr level with the semen volume, sperm concentration, and total sperm count, and the Glu level with sperm concentration and total sperm count. The TG level was correlated positively with the semen volume, but negatively with sperm motility. The levels of seminal plasma ALT, GGT, ADA, UA, TC, CK, and hsCRP showed no correlation with the above-mentioned semen parameters. None of the seminal plasma K+, Na+, Ca, Mg, and P levels was found correlated with semen parameters except the Cl- level, which was negatively correlated with the semen volume.

CONCLUSIONMany biochemical markers in the seminal plasma are closely related to routine semen parameters, indicating that these biochemical components may play roles in spermatogenesis, sperm maturation, and physiological metabolism.

OBJECTIVETo investigate the changes of the mRNA expressions of myocardial cytoskeletal proteins in endotoxemic rats.

METHODSThirty-seven Wistar rats were randomized into two groups with injection of 10 mg/kg lipopolysaccharide (LPS) or normal saline through the femoral vein. The cardiac function of the rats was monitored continuously for 24 h, and the morphological changes of the cardiac myocytes were observed with HE staining and electron microscope. The mRNA levels of myocardial cytoskeletal proteins including actin, tubulin and desmin were determined by RT-PCR.

RESULTSNo significant difference was found in the number of CD3(+)T lymphocytes in the TILs between different groups. After the immunotherapy, the peLPS injection resulted in significant impairment of the cardiac function and myocardial microstructure of the rats with reduced heart rate and left ventricular systolic pressure (LVSP). The mRNA expression of actin in the cardiac myocytes measured by fluorescence optical density was reduced significantly 8 h after LPS injection, and that of tubulin was decreased significantly 24 h after LPS treatment; desmin mRNA expression showed no significant variation after LPS injection.

CONCLUSIONLPS can significantly impair the cardiac function of the rats possibly by inducing damages of the myocardial cytoarchitecture and causing changes in the mRNA expressions of such cytoskeletal proteins as actin and tubulin.

Objective To investigate the value of combined detection of multi-tumor markers in the diagnosis of primary hepatocellular carcinoma (HCC) and to establish the discriminant equation. Methods Using a protein chip, 12 tumor markers in the serum from 98 patients with HCC and 67 patients with benign liver diseasewho had been admitted to Daping Hospital from November 2003 to April 2006, and 46 healthy individuals during he same period were analyzed. A discriminant equation was established to discriminate primary HCC from benign liver diseases. All the data were processed by variance analysis and chi-square test. Results The positive rates of the tumor markers were 89% (87/98) in patients with primary HCC, 19% (13/67) in patients with benign liver disease and 4% (2/46) in healthy individuals. There was statistical difference in the serum level of alpha-fetoprotein (AFP), eareinoembryonic antigen (CEA), ferritin (FER), CA19-9 and CA125 among the 3 groups (F =59.530, 40.472, 31.708, 75. 897, 153.066, P <0.05). Combined detection of AFP, CEA, FER, CA19-9 and CA125 improved the diagnostic accordance rate to 89%, which was significandy higher than the diagnostic accordance rate (64%) when only AFP was detected (X2 = 16.362, P <0.05). The accuracy of the discriminant equation was 90%. Conclusions Combined detection of multi-tumor markers is superior to AFP detection. Combined detection of multi-tumor markers can be used in screening of the HCC patients in HCC high risk population and in the early diagnosis of primary HCC.

BACKGROUND:Human umbilical cord mesenchymal stem cells (hUC-MSCs) can secrete a variety of cytokines and growth factors to support hematopoiesis.They can change the hematopoietic microenvironment,and furthermore,regulate and improve the immune function of the organism.OBJECTIVE:To investigate the effect of hUC-MSCs on immune reconstitution and prognosis in children with acute lymphoblastic leukemia (ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).METHODS:Sixty-four ALL children who had undergo allo-HSCT were enrolled and randomized into non-blood donor allo-HSCT group (n=32) and non-blood donor allo-HSCT+hUC-MSCs group (n=32).The therapeutic effect and complication were observed in the two groups.The changes of immunoglobulins and lymphocyte subpopulations in the two groups were compared before and 1,3 and 6 months after transplantation.RESULTS AND CONCLUSION:Compared with the allo-HSCT group,the time of granulocyte implantation was shorter (P ＜ 0.05),and the incidence of chronic graft versus host disease and cytomegalovirus was lower in the allo-HSCT+ hUC-MSCs group.There were no significant differences in hematopoietic stem cell implantation rate,platelet remodeling rate,cumulative recurrence rate and 1-year survival rate between the two groups (P ＞ 0.05).The levels of serum immunoglobulins IgA,IgG,IgM,IgE and the levels of T lymphocytes (CD4+,CD3+CD4+,CD4+CD8+) and B cells in the peripheral blood of allo-HSCT+hUC-MSCs group were significantly higher than those in the allo-HSCT group at 1,3 and 6 months after transplantation (P ＜ 0.05).In conclusion,the combined use of hUC-MSCs infusion and allo-HSCT can effectively reduce the incidence of chronic graft-versus-host disease,and contribute to granulocyte hematopoietic reconstitution and immune function reconstruction.

BACKGROUND: Acute graft-versus-host disease (aGVHD) is an inflammatory disease mediated by regulatory T cells. It is of certain significance to prevent and treat aGVHD by improving the levels of CD4+CD5+regulatory T cells (CD4+CD5+Treg)and related inflammatory factors in the body. OBJECTIVE: To investigate the effect of granulocyte colony stimulating factor (G-CSF) on CD4+CD5+regulatory T cells (CD4+CD5+Treg) and cytokines in children with hematological malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Seventy children with hematological malignancies undergoing allo-HSCT were enrolled. G-CSF was mobilized in the 45 cases (G-CSF group) before allo-HSCT transplantation. The other 25 cases were assigned to non-G-CSF group. Peripheral blood samples were collected at 4 weeks after allo-HSCT. Another 60 healthy children were selected as control group. The levels of T cells, serum interleukin-35 (IL-35) and interferon-γ (INF-γ) were measured by flow cytometry and ELISA, respectively. According to whether aGVHD occurred after allo-HSCT, the 70 cases were divided into aGVHD positive group and aGVHD negative group. The relationship between the changes of T cells and cytokines with aGVHD was analyzed. RESULTS AND CONCLUSION: (1) The percentage of CD4+CD5+Treg in CD4+T and CD4+FoxP3+T cells as well as serum IL-35 level in children with hematological diseases were lower than those in the control group (P < 0.05), while the levels of INF-γ were significantly higher than that in the control group (P < 0.05). (2) The percentage of CD4+CD5+Treg in CD4+T cells and CD4+FoxP3+T cells as well as serum IL-35 level in the G-CSF group were lower than those in the non-G-CSF group (P < 0.05), while the levels of INF-γ was higher than that in the non-G-CSF group (P < 0.05). (3) There were 7 cases (16%) of aGVHD in the G-CSF group and 10 cases (40%) of aGVHD in the non-G-CSF group at 4 weeks after allo-HSCT, and the incidence of aGVHD was significantly different between the G-CSF and non-G-CSF groups (P=0.022). (4) The percentage of CD4+CD5+Treg in CD4+T and CD4+FoxP3+T cells as well as serum IL-35 level in the aGVHD negative group were higher than those in the aGVHD positive group (P < 0.05), while the levels of INF-γ were significantly lower than that in the aGVHD positive group (P < 0.05). (5) CD4+CD5+Treg and CD4+FoxP3+T cells were positively correlated with the IL-35 level, but negatively correlated with the INF-γ level by Pearson single factor analysis. To conclude, G-CSF mobilization can significantly improve CD4+CD5+Treg cells and its transcription factor Foxp3 after allo-HSCT, which may be useful for improving the therapeutic effect of allo-HSCT and preventing aGVHD in patients with malignant hematological diseases.
