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.

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.

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.

This study was designed to summarize the clinical experience of harvesting the lung of a brain-death donor by international standardized methods so as to establish a set of standards and regulations that are applicable for harvesting the lung of brain-death donors in China. The patient was strictly determined according to international standardized method by two or more advanced neurologists, neurocranial surgeon, anesthetists, and ICU specialists using brain death diagnostic standards and brain death diagnostic technological specification. The family members signed a informed consent of abandoning treatment for brain death and he was a volunteer organ donor. The operation was performed on 1 brain-death donor who had endured 50 hours of mechanical ventilation to evaluate brain death and organ function. The donor was assessed by donor lung function test and international brain death standard. Then the organ was ready for lung transplantation.

Objective To analyze the CT features of hepatic echinococcosis rupture into the biliary tract, and to assess the value of CT study in the diagnosis of such cases. Methods CT findings in 15 cases proved surgically and pathologically were studied and analyzed retrospectively. Results 15 patients had 20 hepatic echinococcosis, including simple echinococcosis with single cyst (9 lesions), simple hydatid cyst with multiple cysts (6 lesions), and multivesicular echinococcosis with multiple cysts (5 lesions). 2 lesions had calcifications on the cyst wall. The rupture of hepatic echinococcosis into the intrahepatic ducts was found in all 15 cases. Meanwhile, 12 of them had rupture into the common bile duct, and 2 into the gallbladder. The main CT findings were hepatic echinococcosis incorporated with the dilatation of the biliary tract. Conclusion Signs of rupture of hepatic echinococcosis into the biliary tract are characteristic in CT studies, providing a reliable evidence for preoperative diagnosis.
