Objective To investigate the effect of ropivacaine and sufentanil alone or in combination with continuous subarachnoid block for labor analgesia.MethodsIn this experiment, 63 cases of spontaneous delivery of labor in First People's Hospital Jiande City from June 2015 to December 2016 were randomly divided into experimental group and control group according to the time of hospitalization.Each 21 cases.In the control group, 1 mg of ropivacaine was treated with 1 mg of ropivacaine (15 mg) and 5μL of sufentanil.The control group 1 was treated with 1% ropivacaine alone.The control group 2 was treated with 6μl of sufentanil.ResultsIn this experiment, the effect of subarachnoid analgesia was VAS score≤3 points, the experimental group was significantly faster than the control group 1, 2 (P<0.05), the first PCEA administration time is subarachnoid The effective duration of analgesia in the experimental group was statistically significant (P<0.05).In addition, VAS score was statistically significant.There was no significant difference between the three groups.In addition, the three groups of maternal active period, the second labor time difference was not statistically significant.ConclusionCompared with the original single use of agents, ropivacaine and sufentanil continuous subarachnoid analgesia for labor analgesia had better effects on maternal effects on labor.

Autogenous vein graft is one of the frequent methods to treat ischemia in Vascular Surgery.However, the patency rate of vein grafts is unhappy because of the injury, the difference structure between arteries and veins, and the change of hemedynamics after grafted. The restenosis of vein graft contains three syntrophic component elements-thrombosis, intima hyperplasia, and scleratheroma. In this article, we will discuss the relationship between the changed hemodynamics and the restenosis of the vein grafts.

Objective To investigate the incidence and influence factors of stress ulcer SU) in traffic injury patients. Methods Clinical data of 362 traffic injury patients were studied retrospectively.Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score was carried out for all the patients.All the patients had gastroscopy and a comparative analysis was done on the SU patients with or without bleeding and the patients without SU. Results The patients with extensive burn in traffic injury were more susceptible to SU as compared with other trauma patients,with statistical difference ( X2 =7.028,P ＜ 0.05 ).The incidence of SU or hemorrhage was increased with higher APACHE Ⅱ score.The incidence of SU hemorrhage in patients with diabetes or cardiopulmonary disease was significantly higher than that in patients without diabetes or cardiopulmonary disease ( P ＜ O.05 ). Conclusions Traffic injury patients should receive routine gastroscopy.APACHE Ⅱ score has some predictive value for SU or hemorrhage.The incidence of SU hemorrhage is also determined by combined factors of underlying diseases and treatment methods.

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood.Radiation therapy has been integrated into the primary treatment of most patients with rhabdomyosarcoma, but which in turn potentially induces severe acute and late toxicities.Proton therapy in recent years has been more and more used in the treatment of rhabdomyosarcoma, which is safe and effective, with no serious adverse events.Compared with conventional photon therapy, proton therapy has distinct physical advantages and enables greater precision in the delivery of tumoricidal radiation doses with reduced irradiation of normal tissues, and improves quality of life for patients.Additional follow-up and prospectively studies are needed to determine whether proton therapy truly reduces the incidence and severity of late effects in comparison to patients treated with modern photon techniques.

Objective To evaluate the value of non invasive examinations in the diagnosis of vascular disease of lower extremity. Methods Segmental systemic pressure (SEG), pulse volume recorder (PVR) and continuous wave (CW) were adopted to examination of 36 patients with arterosclerosis obliterans of lower limbs, and the foundings were compared with that of MRA and operation . Results In all 36 cases, non invasive examinations detected abdominal aorta and common iliac artery with femoral artery occlusion in 12 cases ,femoropoplitea artery occlusion in 28 cases, popliteal artery and the distal artery occlusion in 16 case; MRA together with operation confirmed abdominal aorta and common iliac artery with femoral artery occlusion in 11 cases, femoropopliteal artery occlusion in 32 cases and popliteal artery and the distal artery occlusion in 13 cases. The accurent diagnosis rate of non invasive examination was 85.7%. Conclusions Although PVR has not yet been used to replace the arteriography to directly observe the local situation of arterial lesions , it can preliminarily determine the obstruction sites and severe degree of the occluded arteries. PVR has convenient and reliability in the diagnosis,evaluation of the therapeutic effect and the postoperative follow up of blood vessel diseases,it is worthy to be widely applied in the clinical practice.

BACKGROUND: The study of isolation, purification, culture, cell labeling, inducing factors, effects of gene transfection on cytobiology, cell carrier construction, and time window for back transplantation of cell compound pertaining to marrow stromal cells (MSCs) is still in its infancy. OBJECTIVE: To search for an in vitro culture method that can be simply and effectively obtained. DESIGN, TIME AND SETTING: The present cytological in vitro experiment was performed at the Beijing Institute of Genome, Chinese Academy of Sciences between June 2006 and July 2007. MATERIALS: Eight specific pathogen-free New Zealand rabbits, aged 6 weeks, were provided by the Laboratory Animal Center, Institute of Genetics and Development, Chinese Academy of Sciences. METHODS: Under sterile condition, 1 mL rabbit bone marrow was taken and diluted with D-Hanks solution. Following centrifugation and subsequent supernatant removal, bone marrow was re-suspended using dulbecco's modified eagle's medium (DMEM) for single cell suspension. Next, single cell suspension was dropped onto the liquid surface of equal-volume lymphocyte separation medium (density: 1.077). Subsequent to centrifugation, cloudlike mononuclear cell layer was collected and re-suspended with DMEM containing 20% fetal bovine serum. The cells were inoculated at lxl0/cm2 and purified by adherent method. When 70%-80% of flask bottom was covered, cell digestion and passage was performed.MAIN OUTCOME MEASURES: Cell growth was observed with an operating microscope. Surviving cells were counted by Trypan blue viability test. Cell identification was performed by hematoxylin-eosin staining. Through the use of 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay, cell viability was detected to observe the cellular resuscitation of the cultured cells following cryopreservation. RESULTS: Twenty-four hours after inoculation, cells began to adhere to the wall, exhibiting short shuttle- or triangle-shaped appearance with different sizes of cellular processes. Three days later, adherent cells began to divide, and cell clusters could be found in some areas; One week later, most of cells exhibited scattered fibroblast-like growth; After passage, cells were evenly distributed with long shuttle-shaped appearance and arranged orderly. Following 3 passages, there wound be 5×106-1×107 adherent cells in 1 mL MSC suspension. Approximately 90% of MSCs survived and identified as mononuclear cells. Cells vigorously grew at days 1-6 after inoculation and reached a peak level at day 8, followed by a viability decline. After 56 days of resuscitation, frozen cells displayed a good and rapid growth. CONCLUSION: Highly purified MSCs can be acquired by gradient centrifugation of lymphocyte separation medium. Enough seeded cells can be obtained by in vitro culture and the cellular viability does not change after frozen preservation and resuscitation.
