Objective To observe the therapeutic effects of comprehensive rehabilitation treatment in patients with chronic renal failure (CRF). Methods Fifty patients with CRF were randomly and equally divided into a rehabilitation group and a control group. Those in the rehabilitation group were intervened with comprehensive rehabilitation protocol including regular counseling, health education and adequate aerobic exercise in addition to routine medications, while those in the control group with the routine medications only. The therapeutic effects were evaluated by means of Symptom Check List- 90(SCL- 90) and the questionnaire about quality of life (QOL) for patients with CRF, as well as such biochemical parameters as SCr, BUN, Ccr, DBP and SBP before and after treatment. Results Compared with those in the control group, the physiological capability and other relevant parameters of QOL in the rehabilitation group were significantly improved after one year of comprehensive rehabilitation, while SBP and DBP significantly decreased. There was no statistically significant changes of the concentrations of Scr, Bun, and Ccr. Conclusion Comprehensive rehabilitation intervention is superior to routine drug therapy in terms of improving the physiological capability, decreasing the BP and improving the QOL of the CRF patients.

Objective To investigate the clinical outcomes of alprostadil in prevention of portal vein thrombosis after splenectomy and devascularization.Methods 113 patients with PHT who were treated with prophylactic alprostadil after splenectomy and devascularization procedures from May 2009 to Apr 2013 were included into the treatment group.112 conservative patients with PHT who were treated with traditional prophylactic anticoagulants after the same operations before May 2009 were included as the control group.The postoperative complication rates,mortality,postoperative drainage volume from the abdominal cavity,blood platelet counts,prothrombin time,liver function,Child-Pugh's scores and portal vein thrombosis rates between the two groups were compared.Results When compared with the control group,the postoperative complication rate and mortality in the alprostadil group were not increased,while the postoperative drainage volume from the abdominal cavity was significantly reduced.The increase in blood platelet counts and prothrombin time were similar in the 2 groups.Furthermore,the extent of hepatic dysfunction on the 3rd and 7th after operation was significantly decreased.On short term follow-up,color droppler ultrasonography showed the portal vein thrombosis rate of the treatment group was significantly lower than the control group,with less extensive degree of thrombosis in the treatment group.Conclusion Alprostadil is a safe and effective anticoagulant which provided better prevention of portal vein thrombosis after splenectomy combined with devascularization.

Pancreatic sinistral portal hypertension is a localized kind of portal hypertension that usually occurs as a result of the splenic vein obstruction caused by pancreatic diseases.Furthermore,it is also an important cause of upper gastrointestinal hemorrhage.Management in clinical practice should be directed at the sinistral portal hypertension and primary pancreatic diseases.

Objective To explore the diagnostic value of ultrasound-guided aspiration biopsy in patients with unexplained refractory ascites.Methods The data of 25 cases of unexplained refractory ascites were retrospectively analyzed.For all the cases the diagnosis was based on the examination of contrast enhanced CT or ultrasound.Ultrasound-guided aspiration biopsy of locally thickened peritoneum or ti- ny masses in ascites was performed.Reults Ultrosonographic image of all cases was as follows.10 cases,with locally thickened peritone- um,were isoechoic or hypoechioc.In 2 of 10 cases contrast enhanced ultrasound examination was done,and the images were characterized by an obvious enhancement in arterial phase and quick wash-out in veinous phase.In 7 cases there was irregularly thickened peritoneum, accompanied by adhesion and caking of the omentum.Cystic formation in ascites or in peritoneum was found in 5 cases.Solid mass in asci- tes was found in 2 cases,and splenomegaly and enlarged pancreas were found in 1 case.Ultrasound-gnided aspiration biopsy was perfomed in all the patients.Among them 4 patients were operated on later.Histopathologic examination showed malignency in 20 patients.Among them,malignant peritoneal mesothelioma accoumted for 6 cases,pancreatic cystoadenoma in 2,mestastic adenocarcinoma in 9,malignant schwannoma in 1,lymphoma in 1,and histiocytoma in 1 patient.In the other 5 cases the lesion was benign,and it was verified by follow- up for about 6 months.Among them there were 3 cases of tuberculosis,1 case of inflammatory disease and 1 case of retroperitonesl fibro- sis.Conclusion Ultrasound-guided aspiration biopsy is valuable in the diagnosis of locally thickened peritoneum and tiny mass in ascitic fluid,and is valuable for diagnosis of unexplained refractory ascites.

Objective:To establish an HPLC method for determining the content of aspirin and sodium salicylat in A-Liu spirits and study the stability of the two components under different storage conditions. Methods:The analytical column was Agilent Eclipse XDB-C18(150 mm ×4.6 mm, 5 μm) ,0.01 mol·L-1 potassium dihydrogen phosphate (adjusting pH to 2.3 with potassium acid) -acetonitrile-methanol(55∶15∶30) was used as the mobile phase at the flow rate of 1. 0ml·min-1 , the detection wavelength was 280 nm and the column temperature was 30℃. The contents of aspirin and sodium salicylat were regularly determined under such storage conditions as ambient temperature, constant temperature and humidity(30℃ ± 2℃,65% ± 5%) and refrigeration (4℃ ± 2℃). Re-sults:The average recovery and RSD were 100. 06% and 0. 80%(n=9) for aspirin, and 100. 53% and 0. 82%(n=9) for sodium salicylat. Aspirin and sodium salicylat showed good linear relationship within the range of 31.0-310.0 μg·ml-1(r=0.999 9)and 30. 5-305. 0 μg·ml-1(r=0. 999 5), respectively. Under the three storage conditions, the content of aspirin was decreased, while that of sodium salicylat was increased, suggesting the temperature could significantly affect the hydrolysis rate and content of aspirin Conclusion:The method is promising with good resolution, reproducibility and sensitivity. It is recommended that the method be used to determine the content of aspirin and sodium salicylat in A-Liu spirits, and aspirin isn't stable under different storage conditions.

Background and purpose:Oxaliplatin is a new cytotoxic platinum compound widely used in antineoplastic treatments.Peripheral neuropathy characterized by allodynia remains the most common way to limit the usage of oxaliplatin.Oxaliplatin-associated neuropathic pain is often resistant to standard analgesics.The effects of antidepressant agents such as desipramine and fluoxetine on chemotherapy-induced neuropathic pain were investigated so as to provide experimental evidence for clinical treatment.Methods:A single injection of oxaliplatin(30 mg/kg)intraperitoneal was injected into a test subject,a mouse that had chronic neuropathic pain.Using the von Frey filament as a touch stimulator,the mechanical withdrawal threshold(MWT)was measured when observing allodynia.The MWT was measured before and 1 h after the administration of desipramin and fluoxetine.Results:Desipramine and fluoxetine both have the potential to increase the MWT in mice with oxaliplatin-induced neuropathic pain.Pretreatment with antagonists such as an opioid receptor like naloxone could deepen their effects.Furthermore,when desipramine is combined with an opioid analgesic as buprenorphine,it causes an augmentation in the MWT.Conclusion:Antidepressants desipramine and fluoxetine antagonize oxaliplatin-induced neuropathic pain by inhibiting allodynia.Furthermore,the tricyclic antidepressing agent desipramine could enhance the effects of buprenorphine in subjects with oxaliplatin-induced pain,suggesting a synergistic effect for opioid analgesic.

Objective To explore the reasons and preventive measures of early dislocation after total hip arthroplasty in elder patients. Method A retrospective study was done to analyze dislocation time, reason and time of 168 elderly patients with early anti-dislocation after total hip arthroplasty in joint surgery. Results Only 7 patients (4.1%) had type I joint dislocation, including 2 male and 5 female patients aged 65~89 years. The dislocation happened in 4~5 weeks postoperatively, mainly resulting from hip joint over flexion when urinating in bed, sleep-turning, loaded-moving, walking and stoop and diachoresis. Conclusions For the elderly patients after total hip replacement, it is type I dislocation which happened 4 ~ 5 weeks after operation, more femal than male, reasons including over-exercrse. Effective prevention measures includes regular rehabilitation training, early precautions enhanced mental support and safety nursing.
