BACKGROUND:Platelet-derived growth factor has the ability of wound repair, and relevant studies mainly focus on bone tissue repair. However, there are less studies about the effect of platelet-derived growth factors in skin wound healing. OBJECTIVE:To investigate the role of platelet-derived growth factor to promote wound healing by the regulation of bone marrow mesenchymal stem cels to the wound. METHODS:Bone marrow mesenchymal stem cels from rats were cultured. Immunofluorescence method was conducted to detect cel surface markers of CD34 and CD44 in bone marrow mesenchymal stem cels. Thirty healthy male SD rats were divided into five groups at random. Bone marrow mesenchymal stem cels labeled with PKH-26 were injected into the rat caudal vein in each group. The rats were anesthetized 1 week after injection. On the center of rat back, a 3-cm incision was made to establish a wound healing model. Different concentrations of platelet-derived growth factor were injectedvia multi-points on the skin wound after modeling, and the control group was treated with the same volume of normal saline. Skin wound tissues were taken for relevant parameter measurement at 14 days after injection. RESULTS AND CONCLUSION: Under the fluorescence microscope, platelet-derived growth factor could induce the migration and accumulation of bone marrow mesenchymal stem cels to the trauma in a dose-dependent manner and promote the wound healing. Masson staining showed that, with the concentration increase, platelet-derived growth factors could reduce inflammatory cel infiltration and increase the number of colagen fibers. Results from western blot assay showed that platelet-derived growth factor could inhibit the expression of matrix metaloproteinase-1, promote the expression of tissue inhibitor of matrix metaloproteinase 1 in the wound, and inhibit the colagen degradation, thereby promoting skin wound healing indirectly.

Methods 8 cases of small intestinal autopsy specimens of normal adults, 6 cases of lymphoma specimen of bowel comfirmed by pathology were studied by angiography,pathological diagnosis and quantitative analysis with CMIAS 007 system. Results The lymphoma of bowel was poor in vascularity (P < 0.05) There were significannt difference in the blood vessels such as disorder, tortuous, interruption sign,contrast medium puddle and dyeing of mensentery compared with normal . Conclusion The study on vascular morphology of lymphoma is help for interventional radology and HCT diagnosis.

Objective To observe the effects of mild hypothermia hemofiltration on cerebral blood flow (CBF) and intracranial pressures (ICP) in patients with severe brain injury. Methods 65 patients with severe brain injuries were divided into control group (n=30) and observation group (n=35). The control group accepted the routine treatment only while the observation group accepted mild hypothermia hemofiltration additionally. CBF was detected by Transcranial Doppler (TCD) and ICP was monitored by ICP monitor. Glasgow Coma Scale (GCS) was assessed every day. Results 5 d after treatment, the scores of GCS were higher in the observation group than in the control group (P<0.05) as well as the CBF (P<0.05), but the ICP was in the observation group significantly lower than in the control group (P<0.01). Conclusion Compared with the traditional mild hypothermia, mild hypothermia hemofiltration can improve hemodynamic changes caused by severe brain injury, reduce ICP and improve the outcomes.

ObjectiveTo compare the outcomes of total hip replacement (THR) and minimally invasive dynamic hip screw (MIDHS) in treating osteoporotic femoral intertrochanteric fractures so as to discuss the differences of the two treatment methods.Methods A retrospective study was done on 48 elderly patients with femoral intertrochanteric fractures.All the patients were randomly treated with THR (THR group) and MIDHS internal fixation ( MIDHS group).After a follow-up of over six months,the two groups were compared concerning the operation time,intraoperative blood loss,postoperative drainage,postoperative hip function,and postoperative complications.ResultsTHR group had longer operation time,larger volume of intraoperative bleeding and postoperative drainage as compared with the MIDHS group.The incidence of internal fixation loosening varied significantly with different degree of osteoporosis in the MIDHS group,but not in the THR group.The loosening rate of the implants in the MIDHS and THR groups was 33.3％ and 4.1％ respectively,with significant difference.Functional evaluation of hip showed no significant differences between the two groups six months postoperatively.ConclusionFor achieving earlier and better functional recovery and less postoperative complications in the management of osteoporotic femoral intertrochanteric fractures,MIDHS can be considerel for the elderly patients with low degree of osteoporosis and THR for younger patients with high degree of osteoporosis.

Objective Measuring job satisfaction level of community health workers,providing on the evidences for the design of the relevant policy and the evaluation of job effect.Methods 57 Community Health Service centers and 54 stations were randomly selected in 12 cities in Anhui province,and all staff on the job were investigated.The questionnaires were delivered to the working staff and anonymously filled in by them.Results The total job satisfaction average score of the staff is 110.84± 18.18.The average score of pay(10.05±2.99),welfare(10.35±3.17)and promotion(10.85±3.00)are rather low.The average score of coworkers(14.78±2.11),nature of work(14.60±2.69)and supervision (13.90±3.00)are quite high.Logistic regression analysis shows the staff's duration and title are the main factors affecting their overall job satisfaction.Conclusion The overall job satisfaction level of community health workers is not high.Establishing the reasonable system of pay,welfare mechanism and the predictable promotion space are feasible choices to promote job satisfaction of community health workers

BACKGROUND:How to control the orderly formation of colage in skin repair and scarring process is worthy of attention. OBJECTIVE: To investigate the effect of basic fibroblast growth factor (bFGF) combined with insulin-like growth factor 1 (IGF-1) on the proliferation and colagen synthesis of rat bone marrow mesenchymal stem celsin vitro. METHODS:Rat bone marrow mesenchymal stem cels were isolated and cultured to induce adipogenic differentiation assessed by oil red O staining and osteogenic differentiation identified by alizarin red stainingin vitro. Passage 3 cels were cultured in the medium containing bFGF, IGF-1, combination of them or the control fluid, respectively. MTT assay was used to detect cel proliferation at 12, 24, 48, 72 and 96 hours of culture. The expression of type I colagen and type III colagen were detected by RT-PCR and western blot after 10 days of incubation. RESULTS AND CONCLUSION:Compared with the control group, bFGF or IGF-1 alone significantly promoted the proliferation of bone marrow mesenchymal stem cels, and inhibited the expression of type I colagen and type III colagen. After combined use of bFGF and IGF-1, the proliferation of bone marrow mesenchymal stem cels was improved more significantly, and the expression of type I colagen and type III colagen returned to normal levels. These findings indicate that the combination of IGF-1 and bFGF can promote proliferation of bone marrow mesenchymal stem cels and restrain the expression of type I colagen and type III colagen, which may be helpful for control and repair of scar formation during wound healing.

Objective: To assess the renal cortical perfusion parameters by the imaging of computed tomography (CT) in patients of essential hypertension (EH) with target organ damage.
Methods: A total of 90 subjects with the entire information including 59 EH patients were studied. The EH patients were divided into 2 groups: EH + target organ damage group,n=30 and EH without target organ damage group,n=29. In addition, there was a Control group,n=31 healthy volunteers. All subjects received 128-slice dual-source CT renal perfusion scanning, the quantitative perfusion of renal cortex blood lfow (BF), blood volume (BV), time to peak (TTP) and the mean transit time (MTT) were examined and compared among different groups.
Results: There were 90/97 (92.8%) participants eligible for perfusion analysis. Compared to Control group, EH without target organ damage group had the similar parameters of BF, BV, MTT and TTP,P>0.05. While EH + target organ damage group had decreased BF (214.6 ± 36.1) ml/(min?100 ml ) than Control group (262.1 ± 26.6) ml/(min?100 ml ),P<0.01, and BV, TTP, MTT were similar to Control group,P>0.05. Compared to EH without target organ damage group, the EH + target organ damage group presented decreased BF (214.6 ±3 6.1) ml/(min?100 ml ) vs (268.9 ± 33.1) ml/(min?100 ml ), P<0.01 and prolonged MTT, TTP,P< 0.05.
Conclusion: CT imaging may evaluate the renal cortical perfusion changes, and especially BF which can relfect the renal perfusion more sensitively than other parameters in EH + target organ damage patients.
