Objective To evaluate the efficacy of greenlight photoselective vaporization of the prostate(PVP) for benign prostatic hyperplasia(BPH) in aged patients.Methods A total of 90 aged patients with BPH underwent PVP with an 80 W KTP laser(Laserscope Company) under sacral or peridural anesthesia.Results The operative time was(42.5?18.4)min;the postoperative urinary catheter time was(2.5?0.8)d.Qmax increased significantly from(4.8?1.2)ml/s preoperatively to(18.6?1.4)ml/s postoperatively(t=22.566,P=0.000).International prostate symptom score decreased from(25.5?2.4)points preoperatively to(13.2?1.9)points postoperatively(t=12.286,P=0.000).Residual urine decreased from(76.3?9.4)ml preoperatively to(16.5?2.4)ml postoperatively(t=21.901,P=0.000).Transient dysuria occurred in 4 cases and postoperative delayed hemorrhage in 2 cases.No urinary incontinence occurred.Conclusions PVP for BPH is a safe and effective procedure,and suitable for aged and high-risk patients with BPH.

Objective To improve the pipeline which is the second grade of oxygen pressure reducer in order to reduce the oxygen resistance. Methods This device accesses oxygen storage devices in the original pipeline which absorbs oxygen in the atmospheric with the second grade pressure reducer. Results Accessing oxygen storage devices almost can eliminate the additional resistance which is produced by the second pressure reducer. Conclusion The accessing device fully meets the demand of the people with weak breathing, who accesses oxygen for oxygen therapy via the second grade pressure reducer. Meantime, the device expands the scope of services and efficacy of the medical equipment.

A method based on HPLC-ICP-MS was established to separate the reaction products of ( ethylenediamine) palladium(Ⅱ) chloride([Pd ( en ) Cl2])and 5’-deoxyguanylic acid ( 5’-dGMP). Two reaction products were detected at pH 8. 0 with 25 mmol/L phosphate buffer solution as chromatography eluent. One was the main product with HPLC retention time of 2. 8 min, the other product’s retention time was 3.2 min. According to ESI-MS(MS/MS) study, m/z=510, 511, 512, 514, 516[M+1]+ parent ions ( abundances same to palladium isotopes) were detected. Further analysis showed that the main product was[Pd( en) ( N1-5’-dGMP) ]. However the other product was hardly to be detected by ESI-MS. By using HPLC-DAD and HPLC-ICP-MS, we found that the two reaction products had the same UV absorption spectra and palladium percentage content. Combined with other groups’research, the other reaction product was deduced as dimmer, trimer or tetramer form of[Pd( en) ( N1-5’-dGMP) ]. Further study revealed that[Pd( en) ( N1-5’-dGMP) ] was easily formed in acid solution while its polymer form was generated in alkaline solution. At pH 6. 0, [Pd(en)(N1-5’-dGMP)] was formed within 12 hours with good stability. Research also revealed that the total amount of two reaction products declined as reaction pH climbed.

Objective To study the etiology,pathogenesis,diagnosis and treatment of non-traumatic splenic rupture.Method The clinical data of patients with atraumatic splenic rupture from our hospital were retrospectively analyzed,and the liferatures were reviewed.Results Most cases were male.The average age was high.The etiological factors were diverse,and the most common being blood diseases,virus infection,local inflammation and neoplasm.The pathogenesis is related to splenomegaly,increase in splenic fragility,altered haemostatic mechanisms,malposition of the spleen,and violent contraction of the diaphragm.It is more difficult to arrive at a diagnosis when compared with traumatic splenic rupture.Most patients required splenectomy,especially when the etiological factors were malignant blood diseases or splenic tumors.Some patients received non-operative treatment.The prognosis was related to the etiological factors and age.Conclusions The etiological factors of non-traumatic splenic rupture were diverse,and pathological splenic rupture was most common.A preoperative diagnosis was difficult,and splenectomy was the most common treatment.

Objective To discuss the protective effect of carbon nanoparticles lymphatic tracer on parathyroid glands in the operation of thyroid carcinoma. Methods Retrospectively analyzed the clinical data of 65 thyroid carcinoma patients from January 2014 to October 2014, and they were divided into 2 groups according to whether injected with carbon nanoparticles. The experimental group (30 cases) were injected with carbon nanoparticles in thyroidglands before major procedure, while the control group (35 cases) were not injected. In the experimental group, there were 22 cases accepted total thyroidectomy of the affected side gland + isthmus thyroidectomy + subtotal thyroidectomy of the offside gland, and 8 cases of total thyroidectomy. In the control group, there were 25 cases accepted total thyroidectomy of the affected side gland + isthmus thyroidectomy + subtotal thyroidectomy of the offside gland,and 10 cases of total thyroidectomy. And all the 65 cases ac-cepted centrallymph nodes dissection. Results After carbon nanoparticles injection, central lymph nodes became black while parathyroid glands did not become black. The experimental group showed (2. 6 ± 0. 8) parathyroids each patient, and no parathyroid was cut by mis-take;the control group showed (1. 9 ± 0. 7) parathyroids each patient, and 3 parathyroids were cut by mistake. and the difference between the two groups was statistical meaningful (P<0. 05). There was no permanent hypoparathyroidism in the two groups. There was 1 cases of temporary hypoparathyroidism occured in the experimental group, and 3 cases occured in the control group, and there was no statistical sig-nificance difference between the two groups. Conclusion Carbon nanoparticles is benefit to the identification of parathyroid in surgery, and it can reduce the incidence of inadvertent parathyroidectomy, but it cann’ t reduce the incidence of hypoparathyroidism after procedure.
