Objective To investigate the angioarchitecture and the efficacy of endovascular embolization of uterine fibroids. Methods Bilateral internal iliac and uterine arteriography were performed to domonstrate the angioarchitecture in uterine fibroids with Seldinger technique. The feeding arteries of uterine fibroids were super-selectively embolized. Results The uterine arteries of 30 patients all originated from the iliac arteries of the ipsilateral side. The feeding arteries of uterine fibroids showed bilateral dominance in 16 cases (53%), unilateral dominance in 11 (37%) and unilateral feeding in only 3(10%). All symptoms disappeared after embolization. The fibroids masses decreased averagely by 40% in size at 3-month with ultrasound follow-up, by 55% at 6 months and by 60% at 12 months with a total clinical efficacy of 100%. Conclusions The key to efficacy and prevention of relapse is to understand the angioarchitecture in order to occlude all the pathological vessels in uterine fibroids.

Objective To explore the clinical significance of plasma fibrinogen(FIB)and plasma D-dimer (D-D)changes involved in lung cancer patients before and after interventional therapy.Methods 23 patients with lung cancer,27 cases of normal control group collected at the same time,to compared the difference of plasma FIB between patients with lung cancer and the normal control group.All enrolled patients were treated with bronchial artery infusion chemotherapy.Plasma FIB and D-D of all patients were meas-ured before the first and the third interventional therapy.Results Plasma FIB value of patients before interventional therapy was sig-nificantly higher than that of the normal control group and the group after interventional therapy.The difference between the group after interventional therapy and the normal control group was no significant;Plasma D-D value of patients before and after interven-tional therapy was significant.Conclusion Changes of plasma FIB and D-D before and after interventional therapy in patients with lung cancer are significantly correlated with the severity of the disease and interventional therapy efficacy,which can be used as a ver-y meaningful indicator of interventional therapy.

Objective To explore the correlation between the change of CT value of osteolytic bone metastasis after the treatment of zoledronic acid and bone metabolism before treatment in breast cancer patients.Methods Twenty breast cancer patients with osteolytic bone metastases were diagnosed by 99m Tc-MDP bone scintigraphy and 99m Tc-MDP SPECT/CT ( contain 16-slice spiral CT) for the first time entered this study.After treatment of zoledronic acid for 3-12 months with the same method, 99m Tc-MDP bone scintigraphy and 99mTc-MDP SPECT/CT were peformed in the 20 breast cancer patients again with the same CT scan parameters(voltages:120kV, tube currents:80mA, pitches:3.75mm).With using regions of interesting (ROI)technique, the T/NT value of osteolytic bone metastases in the first 99m Tc-MDP bone scintigraphy were measured.The CT value of same ROI before and after zoledronic acid therapy were measured (CT1 and CT2), and the change of CT value (△CT,△CT=CT2-CT1) were calculated.The correlation between them were analyzed. SPSS 16.0 was applied for variance and linear correlation analyses.Results (1)A total of 30 lesions of osteolytic bone metastases were detected in the 20 breast cancer patients by the first 99m Tc-MDP bone scintigraphy and 99m Tc-MDP SPECT/CT.The CT value before therapy was significantly higher than that after therapy(425 ±152HU vs 120 ±73HU, t=9.95, P<0.01).(2)The change of CT value after therapy was positively correlated with and the T/NT value of osteolytic bone metastasis(r=0.907, P<0.01).(3)The change of CT value of positive lesions after therapy was significantly higher than that of negative lesions by 99mTc-MDP bone scan(W=15,P=0.001). Conclusion 99m Tc-MDP bone scintigraphy provides an effective method to predict the efficacy of zoledronic acid for breast cancer pa-tients with osteolytic bone metastases.The breast cancer patients with high bone metabolism should be recommended zoledronic acid thera-py, conversely should not be recommended.

The root canals of 95 maxillary second primary molars were explored by 10#file combined with 17%EDTA.The canal orifice was observed and orientated by endoscope.Hand instruments were used for root canal preparation and screw conveyor was used to fill the ca-nal with Vitapex paste.MB2 was found in 14 of the 95 molars(14.7%).MB2 orifice was usually located mesially along MB-P.

Objective To investigate the kinetics of PML-RARα fusion gene in acute promyelocytic leukemia(APL)to monitor minimal residual disease(MRD). Methods In induction therapy,consolidation and maintenance therapy courses, PML-RARα fusion gene was performed by RT-PCR. Results The long-term follow-up of 18 cases achieved complete remission (CR),two cases experienced molecular relapse. One case relapsed at 4 months after CR1 and achieved CR2 after induction therapy. However, molecular and hematology relapsed again at 2 months after CR2 and re-achieved CR3. The other case relapsed at 74 months after CR1 and achieved CR2 after induction treatment, who had survived for 106 months until the end of follow-up. Conclusion RT-PCR assay for detection of PML-RARα should be performed regularly during CR period so as to find molecular relapse eady. Hematological relapse could potentially be averted through treatment modification according to molecular monitoring results of PML-RARα.

Objective To study the effect of new barrel theory in improving evaluation of hospitalized patients. Methods Eight hundred hospitalized patients from September 2012 to August 2013 were randomized equally into the control group and the observation group.The last one or two items affecting patient satisfaction from the control group were used as objectives to be improved.Causal effect analysis was done pertinent to the items and the worksheet was bettered and improved and then enforced.The two groups were compared after intervention with new barrel theory in terms of satisfaction of patients during admission and discharge. Result The satisfaction of patients in the observation group during admission and discharge was significantly better than that in the control group(P<0.05).Conclusion The new barrel theory used to detect the flaws in nursing service and improve the workflow can improve assessment from the patients so that the management quality can be enhanced.

Objective To evaluate the efficacy and toxicity of hyperthermia combined with chemoradiotherapy for local advanced cervical cancer. Methods Sixty-eight patients with local advanced cervical cancer were treated. Each patient was given cisplatin at the dose of 20 mg ivgtt dl -2 and 5 -fluorouracil 0.75 ivgtt dl -2, repeating every week, total 3 weeks. Thirty -eight patients received chemoradiotherapy alone. Thirty patients received hyperthermia with deeply focus technology, the temperature was increased and maintained 42.5 ℃ for 30 min at least, within 2 hours following irridiation. Hyperthermia was given twice per week with 7 or 12 sessions, as the same chemoradiation methods as the reference group.After 40 Gy therapy to estimate by cervical examination and ultrasonography, the patients with down stage were for operation, and the others continued to irridiation and additional brachytherapy with californium 252until radical dose. Results All patients were tolerated, fifteen patients of hyperthermia combined group were operated and ten patients of the reference group were operated, the difference was significance (50.0 % vs.26.3 %, P <0.05). The response rate of the combined group was 90.0 %, and the reference group was 84.2 %.The incidence of radiotherapy toxicity of the combined group was not higher than the reference group.Conclusion Hyperthermia combined with chemoradiotherapy can elevate the resection rate and the local control rate, not increase the radiotherapy toxicity and increase quality of life for cervical cancer patients.

Objective To compare the hemodynamics and respiratory mechanics between flexible reinforced laryngeal mask airway (FRLMA) and tracheal intubation (TI) in functional endoscopic sinus surgery. Methods Forty-six patients (ASA) scheduled for selective functional endoscopic sinus surgery under general anesthesia were allocated randomly to either flexible reinforced laryngeal mask airway group (FRLMA, n=23) or tracheal intubation group (TI, n=23) with mechanical ventilation. MAP and HR were recorded before anesthesia induction, before intubation, after intubation immediately, before extubation and after extubation immediately. Parameters for respiratory mechanics included peak inspiratory pressure (PIP), plateau airway pressure (P_(plateau)), mean airway pressure (P_(mean)), positive end expiratory pressure (PEEP), peak inspiratory flow (FI_(max)), peak expiratory flow (FE_(max)), and end tidal CO_2 (P_(Et)CO_2). All of the above indicators were recorded 5, 10 and 15 minutes after intubation. Meanwhile, arterial gas analysis was examined. Complications such as aspiration, coughing, pharyngeal pain, hoarseness, muscular soreness and unseal of FRLMA were followed up 24 hours after extubation. Results MAP and HR were significantly higher in group TI than those in group FRLMA after intubation and extubation (P<0.05). PIP, P_(plateau), P_(mean) and VD/VT were significantly higher in group TI than those in group FRLMA (P<0.05). Complications such as coughing, pharyngeal pain and muscular soreness were significantly lower in FRLMA group than that in TI group (P<0.05). Conclusions The application of FRLMA on functional endoscopic sinus surgery is a simply handling method, with minor laryngeal stimulation during intubation and extubation, more stable hemodynamics, reliable respiratory mechanics and low incidence of postoperative upper airway complications.
