OBJECTIVE:To economically evaluate the therapeutic effects of papaverine of papaverine plus phentolamine on patients with impotence METHODS:100 patients with impotence were divided into two groups The patients in the first group were treated with papaverine alone The patients in the second group were treated with papaverine plus phentolamine RESU_LTS:The therapeutic rates were 94% and 96% in group Ⅰ and group Ⅱrespectively CONCLUSION:Both therapeutic schemes were effective in treating impotence,however,combined use was slightly better The single use of papaverine is simpler and cheaper

Objective To compare biomechanical performances of parallel plate fixation and vertical plate fixation for better clinical treatment of humeral intercondylar comminuted fractures (HICF).Methods Models of T-shaped fracture were created using an osteotome at the distal end of humerus in 6 specimens of upper limb in 3 human adult cadavers.The 2 fracture models of left and right humeri in the same cadaver were respectively fixated with parallel plating and vertical plating.On a biomaterial-testing machine,a vertical load was applied onto the fixated distal humerus at a speed of 5 N/s till it reached 2000 N.The loading was repeated 3 times.Vertical compression displacement,intercondylar separating displacement,deformation of medial and lateral condyles and vertical compression stiffness were documented for statistic analyses. Results Under the same load,parallel plating led to significantly less compression displacement,separating displacement and deformation of condyles( P ＜ 0.05) but significantly greater axial compression stiffness( P ＜ 0.05) than vertical plating. Conclusion In biomechanics,parallel plate fixation has better performance than vertical plate fixation for HICF.

Objective To investigate the therapeutic effect of acupuncture for restoring consciousness and inducing resuscitation in promoting revival of coma for the patient of diffuse axonal injury(DAI). Methods 60 cases of DAI (GCS≤ 8) were randomly recurited into a control group and a treatment group. The control group was treated by routine treatment, while the treatment group was treated with acupuncture on the basis of routine treatment .The improving rate of consciousness at the two months of treatment was compared between the two group, and the prognosis was evaluated according to GOS scores. Results The revival rate in the treatment group was 86.7%, higher than that of 60.0% in the control group (P<0.05). The revival time in the treatment group was shorter than the control group (X2=5.45、 t= 8.051, P<0.05 ) .Conclusion The integrated therapy of acupuncture for restoring consciousness and inducing resuscitation and western medicine can promote the effect of coma revival and improve life condition for the patient of DAI.

Objective To investigate the effects of recombinant human granulocyte colonystimulating factor(G-CSF) on murine thymic emigration and subsets reconstitution after a sublethal dose of irradiaton.Methods Female BALB/c mice were irradiated with a 6.0 Gy of γ-ray total-body irradiation and then randomly divided into GCSF group and control group.For mice in the GCSF group,recombinant human G-CSF 100 μg · kg-1 · d-1 was injected subcutaneously once daily for 14 continuous days and mice in the control group were given the same volume of phosphate buffered solution (PBS).At 7,14,21 and 28 days later,mice were killed and thymus mononuclear cell suspension were analyzed by flow cytometry for the percentage of the four stages of thymic CD4 -CD8 - double negative cells (DN1-4) and the CD4 + CD8 + double positive ( CD4 + CD8 + DP),CD4 + CD8 - single positive ( CD4 + SP),CD4 -CD8 + single positive cells (CD8 + SP).Real-time PCR was used for detection and quantitation of murine T cell receptor rearrangement excision circles(sjTRECs) of the thymic cells of 30 and 60 d after irradiation.Results The percentage of thymic DN1 cells in GCSF group was significantly higher than that of the control group 7 d after irradiation (t =9.59,P ＜ 0.05 ).21 d later,the proportion of thymic DN3 and DN4 cells were higher than those of the control group ( t =16.37,7.6,P ＜ 0.05 ).The percentage of thymic CD4 + CD8 + DP cells decreased 7 d after irradiation,increased at 14 d,decreased again at 21 days,and then got a permanent recover.The percentage of thymic CD4 + CD8 + DP cells in the GCSF group recovered to normal and was significantly higher than that of the control group 28 days after irradiation (t =12.22,P＜ 0.05).The percentage of thymic CD8 + SP cells of the GCSF group was significantly higher than that of the control group 21 d after irradiation ( t =3.77,P ＜ 0.05 ),while G-CSF had no obvious influence on the percentage of the thymic CD4 + SP cells.The sjTRECs copies in the GCSF group was significantly higher than that of the control group 30 d after irradiation ( t =5.95,P ＜ 0.01 ),which disappeared 60 d later.Conclusions G-CSF could promote the proliferation and differentiation of thymic DN and DP cells,enhance the recent thymic emigrants and accelerate central immunologic reconstitution after acute irradiation.

Objective To compare the incidence of pancreatic fistula after hand and stapler suture in preventing pancreatic fistula after distal pancreatectomy.Methods The literatures published before December 2011 were retrieved from SinoMed and electronic database.Prospective controlled trials and retrospective reports were screened out for Meta analysis.The diagnostic criteria of pancreatic fistula were based on the criteria formulated by the International Study group of Pancreatic Fistula.The heterogeneity of the studies was analyzed using the Ⅰ2 test.The data were integrated using the fixed or random effect model.The results of the Meta analysis were presented with odds ratio (OR) and 95％ confidence interval (95％ CI).Results According to the selection criteria,lO literatures were selected which included 1 prospective randomized controlled study,3 prospective nonrandomized controlled studies and 6 retrospective studies.There were 1 441 cases in the hand suture group and 612 cases in the stapler suture group.There was no significant difference in the incidences of the pancreatic fistula between the hand suture group and the stapler suture group (OR =1.10,95％ CI:0.86-1.40,P ＞0.05).Six studies compared the incidences of severe pancreatic fistula (grade B or C) between the hand suture group and the stapler suture group.There were 1 182 cases in the hand suture group and 383 cases in the stapler suture group.There was no significant difference in the incidence of severe pancreatic fistula between the hand suture group and the stapler suture group (OR=1.33,95％CI:0.94-1.88,P＞0.05).Conclusion The efficacies of hand suture and stapler suture in preventing pancreatic fistula after distal pancreatectomy are comparable.Stapler suture provides an another option in distal pancreatectomy.

Objective To study the correlation between the genes of killer immunoglobulin (Ig)-like receptors (KIR) in natural killer cells and leukemia. MethodsPrimers of 16 KIR genes, including KIR2DL1-5, KIR3DL1-3, KIR2DS1-5, KIR3DS1 and 2 pseudogenes 2DP1 and 3DP1, were designed and synthesized. A polymerase chain reaction with sequence-specific primers (PCR-SSP) was developed to detect the mRNA expressions of the 16 genes. Totally 46 healthy individuals and 46 leukemic patients (15 cases of acute myelocytic leukemia, 13 cases of chronic myelocytic leukemia and 18 cases of acute lymphocytic leukemia) were detected and the frequencies of the KIR genes were analyzed. ResultsThe frequency of 2DL4, 3DL2, 3DL3 and 2DP1 in healthy and leukemic patients were 100%, and were detected in all patients and healthy individuals. The other KIR genes had similar frequencies except those of 2DL2 and 2DS2, which were 47.8% of the healthy individuals and 89.1% in leukemic patients. There was a significant difference between the 2 groups.ConclusionThere may be an association between pathogenesis of leukemia and 2DL2 and 2DS2 genes.

Conclusions Prenatal ultrasonography is signiifcant in detecting serious fetal malformations, such as hydrocephaly, heart abnormalities and characteristic ultrasound features such as intracranial calciifcations, echogenic bowel, placenta abnormal calciifcation complicated with TOX, RV, CMV and HSV infection, providing valuable information for further clinical treatment, such as induced labour.

BACKGROUND: At present, treatment of diabetes mellitus with western medicine starts from the angle of stimulating injured β cell of islet to strength insulin secreting. Treatment with traditional Chinese medicine is very important in protecting injured β cells.OBJECTIVE: To observe the protective effect of lycium barbarum polysaccharide and nourishing yin and activating blood compound recipe on pancreatic islet function in rats with streptozotocin-induced diabetes mellitus.DESIGN: A randomized and controlled animal experiments.SETTING: First Affiliated Hospital and Medical College of Henan University of Science and Technology.MATERIALS: Totally 70 male Wistar rats, aged 6 weeks, with body mass of 200 g, were used in this experiment.METHODS: This experiment was carried out at the Animal Room of Henan University of Science and Technology from October 2001 to April 2002. Totally 70 rats were divided into two groups: normal control group (n=10) and modeling group (n=60). Totally 30 successful model rats were randomly subdivided into 3 groups: streptozotocin model group, compound recipe treated group and lycium barbarum polysaccharide-treated group,with 10 rats in each group ;Intragastric administration of 60 g/kg Chinese herb compound recipe for nourishing yin and activating blood was performed on the rats in the compound recipe treated group at 9:00 every day (huangqi, shanyao, gegen respectively 30 g, gouqizi, danshen, huafen,digupi respectively 15 g, danggui, zhimu respectively 12 g, danpi, wuweizi respectively 10 g, shuizhi 5 g, shanyurou 20 g, etc, provided by drug store of First Hospital Affiliated to Henan University of Science and Technology,were decocted and condensed to be equivalent crude drug 3.0 kg/L with routine method). Intragastric administration of 0.5 g/kg lycium barbarum polysaccharide was given in the lyciun barbarum polysaccharide treated group (lycium barbarum polysaccharide was isolated and purified from ningxia barbary wolfberry fruit). Intragastric administration of comparative volume of normal saline was performed in the streptozotocin model group and normal control group, totally 3 weeks. The levels of fasting blood glucose (FBG) and insulin were measured at 3 weeks before and after experiment, and function index of β cell of islet was calculated; Pancreas was taken out to detect SOD activity, NOS activity and concentrations of NO and MDA were also detected.RESULTS: Ten rats in normal control group and 30 successful model rats in model group entered the stage of result analysis. ① In the initial stage of experiment, FBG level in each modeling group was significantly increased (t=16.51 to 10.07,P ＜ 0.01), while fasting insulin level and function index of β cell were significantly decreased (t=13.64 to 100.99 ,P ＜ 0.01 ) in comparison with normal control group. ② At 3 weeks after experiment, levels of FBG, NO , MDA , NOS activity were significantly decreased in the compound recipe treated group and lycium barbarum polysaccharide group compared with streptozotocin model group (t=8.08 to 72.68 ,P ＜ 0.01 ), while level of fasting insulin and function index of β cell, SOD activity were significantly increased in the compound recipe treated group and lycium barbarum polysaccharide group compared with streptozotocin model group (t=4.39 to 17.87,P ＜ 0.05-0.01 ). ③ Levels of FBG and MDA , NOS activity and concentration of NO were significantly decreased in the compound recipe treated group, and fasting insulin and function index of βcells were significantly increased in comparison with lycium barbarum polysaccharide group(P ＜ 0.01 ).CONCLUSION: Lycium barbarum polysaccharide and nourishing yin and activating blood compound recipe increase the level of fasting insulin and function index of βcell of rats with streptozotocin induced diabetes mellitus, decrease the level of blood glucose, improve the function of βcell of islet, which might be related to the increase of pancreatic islet SOD activity and decrease NOS activity.

Objective To explore the diagnostic value of ultrasonography of fetal congenital cystic adenomatoid malformation of the lung (CCAM), and to predict the prognosis according to ultrasonographic findings. Methods The chest of 19 fetus with CCAM was multi-sectionally scanned with two-dimensional ultrasonography. The position, appearance and size of mass were observed, and complications were continuously followed. Results CCAM was pathologically confirmed in 13 fetus after induced abortion. One neonatal died, while CCAM in other 5 fetus disappeared before 36 weeks. The mass of typeⅠCCAM became smaller and smaller, and eventually disappeared. The echo-free spaces in typeⅡbecame smaller and fewer, and the strong echo weakened to the same level as normal lung. For type Ⅲ, the echo of solid mass weakened to the same level as normal lung, or transformed to typeⅡ gradually, and finally recovered to normal echo of lung as the gestational age increased. During follow up, there were 10 fetus (10/19, 52.63%) that lung adenoma cyst increased with the gestational age increased, and the heart, mediastinal shifted, pleural effusion, and (or) fetal edema were observed. Conclusion Ultrasound examination is a reliable method for the diagnosis of CCAM, and enable to predict the prognosis of the affected fetuses. If heart and mediustinum displacement, pleural effusion, hydrops fetal or other abnormalities exist, it's necessary to terminate the pregnancy.
