Objective:To solve the problem of treating trauma limbs according to the requirement of therapy and care with the most effective method and the least cost, while the method should be clinical facilitated. Methods:The major part is a long squared mask made of light material with two gabs in each tips, one is smaller, the other is bigger, which just suit with the trauma limbs and hold them(legs or arms). We designed a window at the top of the mask, and some slots around the window. And the appendix boxes in the slots can be added or changed according to clinical therapy. Results:Simple isolated therapeutic mask for limbs can be used only as a simple facility for trauma limbs isolation, and also can be used as a facility of warming, heating, irradiation and sterilization. Conclusion:Simple isolated therapeutic mask for limbs has been admitted as a patent of utility model by State Intellectual Property Office (SIPO) (patent number:ZL200620073372.8). The mask features simple manufacture, low cost, easy to use and reliable effects, can be used not only in every kinds of hospital, but also at home.

【Objective】 To assay the naringenin content in different medicinal materials of Exocarpium Citri Grandis (ECG). 【Methods】 High performance liquid chromatography (HPLC) was applied to determine the naringenin content in different medicinal materials of ECG. The chromatographic conditions were: gradient elution being performed with methanol as mobile phase A and water - acetic acid (61: 4) as mobile phase B, flowing rate being 1.0 mL/min; detecting wavelength at 283 nm. 【Results】 In the rage of 0.088～0.880 ?g, naringenin showed a good linearity with the chromatographic peak area, r=0.9999, average recovery rate was 95.49% and RSD=2.00% (n=5). The naringenin content in 23 different samples of ECG was in the range of 0.1～1.0 mg?g~(-1). 【Conclusion】 It is the first time to establish the HPLC method for the determination of naringenin content in ECG and the method is accurate and reproducible. Naringenin content in varieties of ECG is stable and the difference of naringenin content between Citrus grandis Osbeck. Var. tomentosa Hort. and Citrus grandis (L.) Osbeck is not significant.

Objective To discuss the techniques and efficacy of Ho:YAG laser incision by using uteroscopy for ureterostenosis.Methods From July 2004 to April 2007,52 patients with ureterostenosis received ureteral incision by using Ho:YAG laser under a endoscope.Two double pigtail stents(F5 or F6) were placed in the ureters after the operation and left indwelling for 8 to 12 weeks.Ultrasonography and excretion urography were performed 3 to 6 months after extubation.Results Follow-up was available for 3 to 24 months(mean,17 months) in 46 patients,of which 40(87%) were cured after the treatment.In the cured patients,hydronephrosis,ureteral dilation,and ureterostenosis were improved,and the pain in the kidney region was relieved;none of them showed signs of infection.In the other 6 patients,4 were improved after the treatment(no deterioration of the symptoms of hydronephrosis,ureteral dilation,and pain in the kidney region,and no infection);and 2 failed(the symptoms of hydronephrosis and ureteral dilation deteriorated,and pain in the kidney region and infection were developed).Conclusion Endoscopic ureteral excision using holmium laser combined with indwelling of two double pigtail stents is effective and safe for ureterostenosis.

With the development of techniques and methods of medical researches, the ethic review of clinical research has become essential for healthy development of medical research. This article analyseds the practice of ethic reviews of research projects involving human subjects in our hospital and the difficulties in the process are discussed.

Objective To report the clinical observation and nursing points for recurrent or refractory and aggressive non-Hodgkin's lymphoma treated with MINE regimen. Methods Patients (46 cases) with recurrent or refractory and aggressive non-Hodgkin's lymphoma were given mental nursing,preparation and evaluation of the condition of patients before chemotherapy. Complications especially extravasation of infusion fluid should be prevented during chemotherapy and myelosuppression and long-term complications should be prevented after treatment. Results No patient died after treatment but several complications such as infection(14 cases), nausea and vomiting (grade Ⅰ～Ⅱ, 22 cases, grade Ⅲ,2 cases), alopecia (grade Ⅰ～Ⅱ, 27 cases), mucositis (grade Ⅰ～Ⅱ, 4 cases), liver function lesion (grade Ⅱ, 1 case) were found and improved after proper treatment. No nephrotoxicity and hemorrhagic cystitis were found. Conclusions Selective mental nursing,proper chemotherapy preparation,evaluation of patients' condidtion and positively prevention of chemotherapy-related complications could increase the chemotherapy effect of patients with recurrent or refractory and aggressive non-Hodgkin's lymphoma.

OBJECTIVE:To establish the quality standards of processed Sophora japonica.METHODS:Different batches of processed S. japonica products were detected in respect of property,microstructure,TLC,moisture,total ash,acid insoluble ash,extract inspection,content of total flavonoids and rutin. RESULTS:The limit value of test term for S. japonica,stir-baked S. japonica,S. japonica carbon were confirmed. CONCLUSION:Established standard is applicable for the quality control of processed S. japonica.

AIM: To explore the effect of L-arginine (L-Arg) on the arrhythmia induced by ischemia/reperfusion (IR) of the right coronary artery in rabbits. METHODS: 48 healthy adult rabbits were divided into 4 groups (n=12 of each) randomly: IRa group (120 min reperfusion after 30 min ischemia), IRb group (120 min reperfusion after 120 min ischemia), IRa+L-Arg group and IRb+L-Arg group. I/R model was established by occluding and loosening the root of the right coronary artery in rabbits. The changes of ECG and arrhythmia were recorded and graded. RESULTS: ① The longer time of IR was, the higher the score of the arrhythmia was found. The incidence of atrial-ventricular block (AVB), sinus-atrial block (SAB), even sinus arrest were detected and aggravated gradually. ② The incidence of AVB was decreased and from Ⅲ?→Ⅱ?→Ⅰ? markedly, some of sinus and atrial arrhythmia were transformed into sinus rhythm gradually, and all of the arrhythmia scores in IRa group were decreased significantly as compared with the same time phases of IRb group (P

0.05). In the group of pirenzepine, the RBF, velocity and volume significantly increased at 0.5 h and 1 h after injection compared with that before injection (P0.05). Conclusion These results suggest that pirenzepine could increase RBF and oxygen in blood with the peak time at 0.5 h and 1 h after intravitreous injection.

Objective To investigate the significance of detection of blood coagulation and fibrinolytic indexes before and after delivery.Methods 212 cases in the postpartum hemorrhage group(bleeding amount ≥500 mL)and 235 cases in the normal deliver-y group were retrospectively analyzed.The prothrombin time(PT),international normalized ratio(PT-INR),activated partial throm-boplastin time(APTT),thrombin time(TT),fibrinogen(FIB),D-dimer(DD),blood platelets(PLT)and hemoglobin(HB)were de-tected before delivery and at 72 h after delivery.85 women with the physical examination were selected as the healthy group.Results Before delivery,PT/PT-INR,APTT,TT,PLT and HB in the normal delivery group were lower than those in the healthy group, while FIB and DD were higher than those in the healthy group;PT/PT-INR,APTT,TT and DD in the postpartum hemorrhage group were higher than those in the normal delivery group,while FIB and PLT were lower than those in the normal delivery group. At 72 h after delivery,there was no statistically significant differences in PT/PT-INR,APTT,TT and DD between the normal de-livery group and the healthy group(P >0.05),but FIB was higher than that in the healthy group;PT/PT-INR,APTT,TT and DD in the postpartum hemorrhage group were higher than those in the normal delivery group,while FIB,PLT and HB were lower than those in the normal delivery group.Conclusion Dynamically monitoring the change of the blood coagulation and fibrinolysis indexes before and after delivery has important significance in preventing postpartum hemorrhage and thrombosis.
