Objective To explore molecular mechanism and the curative effect of Yisuishengxue powder and its function of the hepersensitive site 2 (HS2) in ?-globin gene cluster locus control region binding with nucleoprotein.Methods After 3 months treatment of Yisuishengxue powder, nucleoprotein was extracted from the morrow cell before and after treatment. The HS2 DNA probes was combined with nucleoproteins.Electrophoresis gel mobile lag was utilized for observing the mobile velocity of DNA segment.Observe the mobile velocity of DNA probes.Results The mobile velocity of probes combined with nucleoproteins before treatment was different form that of the controls, while it was very close to the controls after treatment.Conclusions It is suggested that this compounding medicine might affect the DNA segment of HS2 site in ?-LCR binding with nucleoprotein GATA-1, which may be one molecular mechanism of Chinese herb therapy.

Objective To explore the necessity of opening nephrostomy tube for patients with septic shock follow-ing the indwelling double-J stent of post-percutaneous nephrolithotomy (PCNL),and provide reference for the treatment of septic shock after PCNL.Methods 60 patients with septic shock after PCNL in a hospital from January 1,2015 to December 30,2016 were chosen,patients were randomly divided into clipping nephrostomy tube group (clipping group,n =30) and opening nephrostomy tube group (opening group,n =30),clinical data of two groups of patients were collected and analyzed.Results After 24-hour treatment,heart rate (HR),mean arterial pressure (MAP),oxygen saturation (SpO2),serum lactate (Lac),and hourly urine volume all improved in both groups of patient compared with pre-treatment(all P＜0.05);HR,MAP,SpO2,Lac,and hourly urine volume in opening group after 24-hour treatment were all significantly different from clipping group (all P＜0.05).Levels of serum procalcitonin (PCT) and C-reactive protein (CRP) in two groups after 3-day treatment decreased significantly compared with pre-treatment (both P＜0.05);PCT and CRP levels in opening group after 3-day treatment were both significantly lower than clipping group (both P＜0.05);cure rate of two groups were both 100.00％,hospitalization time and extubation time in opening group were both shorter than clipping group,and cost was less than clipping group,difference were all significant(all P＜0.05).Conclusion Opening nephrostomy tube on the basis of indwelling double-J stent is necessary for patients with septic shock after PCNL.

OBJECTIVETo explore the feasibility of evaluating complete ischemia-reperfusion injury (IRI) of the testis by contrast-enhanced ultrasonography with microbubbles (MB) targeted to P-selectin (MBp) in rabbits.

METHODSWe randomly divided 30 healthy adult rabbits into five groups of equal number (control, 0.5 h IRI, 1 h IRI, 2 h IRI, and 4 h IRI), prepared phospholipid MB and MBp, and performed contrast-enhanced ultrasonography of the bilateral testes with MB or MBp at an interval of 20 min at different times after IRI. When MB or MBp disappeared completely in the healthy testis at 4 to 5 min after intravenous injection, we recorded the power of the first frame (F-P) in the IRI testes followed by immunohistochemical staining of the testis tissue.

RESULTSCEU with MBp achieved a significantly higher F-P than that with MB in all the IRI groups (P < 0.05), which was (8.34 +/- 1.20) versus (1.87 +/- 0.25) 10(-5) AU at 2 hours, but there was no significant difference between MB and MBp in the control rabbits (0 AU, P > 0.05). Immunohistochemistry showed a significantly time-dependent increase in the expression of P-selectin in the vascular endothelial cells of the IRI testes, but not in those of the control.

CONCLUSIONContrast-enhanced ultrasonography with MBp can be used to evaluate the inflammatory reaction of testicular ischemia-reperfusion injury.

OBJECTIVETo investigate the mechanism of yisui shengxue granule (YSG) in children with betathalassemia.

METHODSThe changes of hemoglobin (Hb), red blood cells (RBC), reticulocyte (Ret) and fetal hemoglobin (HbF) of 20 children with beta-thalassemia were measured before and after treatment. The effect of YSG on gene expression in myelo-karyocytes in 3 selected children treated effectively by YSG was determined by using DDRT-PCR.

RESULTSThe hematologic parameters were significantly enhanced and the ferritin gene expression declined after treatment respectively, as compared with those before treatment, the difference were significant (P < 0.01 or P < 0.05).

CONCLUSIONYSG could improve the clinical symptoms of children with beta-thalassemia. One of its therapeutic mechanisms may be its action in decreasing ferritin gene expression so as to effectively relieve the accumulation of iron in body.

PURPOSEThis study aims to explore the biomechanical mechanism of lower limb injuries to the driver by establishing a finite element (FE) simulation model of collisions.

METHODSFirst a minibus FE model was integrated with a seat belt system. Then it was used to rebuild two collisions together with the total human model for safety (THUMS) provided by Toyota Motor Corporation: a rear-end collision between a minibus and a truck and a head-on collision of a minibus to a rigid wall. The impact velocities of both collisions were set at 56 km/h. The vehicle dynamic response, vehicle deceleration, and dashboard intrusion in the two collisions were compared.

RESULTSIn the minibus rear-end truck collision, the peak values of the von Mises equivalent stress at the tibia and the femur were 133 MPa and 126 MPa respectively; while in the minibus head-on rigid wall collision, the data were 139 MPa and 99 MPa. Compared with the minibus head-on rigid wall collision, the vehicle deceleration was smaller and the dashboard intrusion was larger in the minibus rear-end truck collision.

CONCLUSIONThe results illustrate that a longer dashboard incursion distance corresponds to a higher von Mises equivalent stress at the femur. The simulation results are consistent with the driver's autopsy report on lower limbs injuries. These findings verify that FE simulation method is reliable and useful to analyze the mechanisms of lower limb injuries to the driver in minibus frontal collisions.

OBJECTIVETo study the clinical effect and security of Yisui Shengxue Granule (YSG) in treating beta-thalassemia.

METHODSOne hundred and fifty-five patients with beta-thalassemia from high-incidence area in Guangxi Zhuang Autonomous Region were treated with YSG for 3 months. Clinical symptoms and levels of hemoglobin (Hb), red blood cell (RBC), reticulocyte (Ret) and hemoglobin F (HbF) were observed before and after treatment, and the adverse reaction occurred in the therapeutic course was observed as well. A 3-6 months follow-up study was performed after withdrawal of YSG.

RESULTSLevels of Hb, RBC, Ret and HbF obviously elevated, and clinical symptoms markedly improved in patients after treatment since the 1st month to the 3rd month (all P < 0.01). Dynamical observation showed that the improvement of symptoms was in accordance with the elevation of hemorrheological indexes. The treatment was effective in 145 patients and ineffective in 11, and the total effective rate being 92.9%, without any adverse reaction occurred. Follow-up study showed the therapeutic effect could be sustained for 3 to 4 months.

CONCLUSIONYSG has evident effect on alpha-thalassemia without obvious adverse reaction, which provides a definite basis for treatment of beta-thalassemia with TCM.

OBJECTIVE: To evaluate the relationship between serum levels of soluble Fas(sFas), soluble Fas li gand(sFasL), soluble IL-2 receptor(sIL-2R) and coronary heart disease (CHD). METHODS: With enzyme-linked immunosorbent assay (ELISA) tests, sFas, sFasL and sIL-2R were measured in the sera from 30 patients with CHD and 26 subjects without CHD as controls. RESTULTS: Mean level of sFas was significantly higher in patients with CHD than in controls [(1 583.41+/-174.46)ng/L compared with (1 374.55+/-142.42)ng/L, P<0.01]. Compared with the controls, the mean level of sIL-2R was significantly higher in patients with CHD [(944.50+/-395.59)ng/L compared with (652.45+/-163.36)ng/L P<0.01]. Moreover, in patients with CHD sFas and sIL-2R were positively correlated (r=0.418 P<0.05). Whereas no such difference was found between both groups in sFasL (P<0.05). CONCLUSION: High levels of serum sFas and sIL-2R were associated with CHD, and elevation of sFas may inhibit apoptosis in activated T cells, leading to coronary events.
