In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

Phytochemical investigation of the roots of Scrophularia buergeriana Miq. (Scrophulariaceae), resulted in the isolation of a new iridoid derivative named as buergerinin (1). Its structure was elucidated as rel-(1R, 5R, 6R)-(2-oxa-bicyclo[3.3.0]oct-7-en-6, 7-diyl)dimethoxypropane based mainly on MS and 1D and 2D NMR spectroscopic analyses.

This dissertation is to determine the biopotency of hemostat which processed in different places by establishing a bioassay method of Bletillae Rhizoma based on the thrombin time. Contrast test is the main methodology. Specifically, the reference substance of Bletillae Rhizoma is determined by comparing with the control substance of vitamin K1 using thrombin time, which is calibrated the Bletillae Rhizoma. The hemostatic biopotency is calculated by using the method of "parallel line assay method based on quantitative responses" (3.3) from different processed products. It indicates that there is a strong linear correlation between Bletillae Rhizoma and control drugs (Y = 66.332-23.913X, R2 = 0.995 3). The hemostatic biopotency of Bletillae Rhizoma from different processed products ranged between 821.93-1 187.53 U x g(-1) shown in the paper, and all of them can meet the requirements of the test. The methodology has an appropriate instrument precision (RSD 3.8%), intermediate precision (RSD 4.6%), repeatability (RSD 3.2%) and stability (RSD 3.7%). Therefore, it can be turned out that the methodology which established in the dissertation is good at determinating the hemostatic biopotency of Bletillae Rhizoma and it is reliable, simple and repeatable.

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.

RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).

CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

OBJECTIVETo search for an effective therapy for infantile nasal obstruction.

METHODSOne hundred and twenty-five cases were randomly divided into an observation group of 62 cases and a control group of 63 cases. The observation group were treated with bilateral Yongquan (KI 1) application with Biyankang Tablet, once each night and the control group with dropping of 0.5% Ephedrine naristillae into the nose, one drop each nose each time, tid. The score for nasal obstruction were recorded before treatment and the third and the fifth days after treatment, and their therapeutic effects were assessed.

RESULTSAfter treatment, the symptom of nasal obstruction was significantly improved in the two groups (P < 0.01), with no significant difference between the two groups (P > 0.05). After treatment for 5 days, the effective rate was 76.8% in the observation group and 79.7% in the control group, their therapeutic effect being similar (P > 0.05).

CONCLUSIONYongquan (KI 1) acupoint sticking therapy is a safe and effective method for infantile nasal obstruction.

A 77-year-old man was admitted to our hospital at July 5th,2010 with an unexplained massive pericardial effusion for 10 years.With dyspnea for one month and normal vital signs without pulsus paradoxus,other physical examination included a small amount of moist rale,normal heart sounds,jugular vein engorgement,positive hepatojugular reflux,hepatosplenomegaly and pitting edema of the extremities.The patient had a complex past history with lymph node tuberculosis,primary artertial hypertension,polycythernia vera,chronic renal insufficiency and hypothyroidism (Hashimoto's thyroiditis),and moreover,received a high dose radiation of 31p in 1967. Family history is negative.The patient had no cardiac tamponade or pericardial constriction during 10 years,he received pericardiocentesis twice,and pericardial effusion was exudative with a high proportion of monocyte.There was no evidences of tuberculosis infection,hypothyroidism,malignant tumor,severe heart failure,uremia,trauma,severe bacterial or fungus infection,chronic myeloid leukemia or bone marrow fibrosis during the admission. The patient refused anti tuberculosis,indwelling catheter drainage or surgical therapy.In this rare case,the aetiology of chronic massive pericardial effusion is most probably chronic idiopathic recurrent pericarditis.

Morphological characteristics of hyphal interaction between Grifola umbellata (Pers. Ex Fr.) Pilat and its companion fungus which related to sclerotia formation from hyphae were investigated by external observations, light microscopy and transmission electron microscopy (TEM). External observations showed that a dense antagonism line was formed by both G. umbellata and companion fungus after their hyphae contacted each other in dual culture. Many hyphal strands emerged on the colony of G. umbellata and differentiated to sclerotia from where hyphal strands crossed. Light microscope observations revealed the process of antagonism line formation. Mature antagonism with structural differentiation, was composed of three main layers: the rind, the rind underlayer and the hypha layer. TEM observations showed that after colonies hyphal contact, a series of reactions always occurred in both G. umbellata and companion fungus. Cells in the center of antagonism line were dead. Cells of G. umbellata adjacent to the antagonism line were usually large and hollow, with unilateral thickened wall, whereas those of companion fungus were empty, with thin or thick wall. Both hyphal interaction at the antagonism line may be one of the main reasons for sclerotia of G. umbellata differentiation from hypha.
