Objective To analyze the causes and management of the late complications after transurethral resection of the prostate (TURP) for benign prostatic hyperplasia. Methods The clinical data of 102 patients who were hospitalized for the late complications after TURP were analyzed retrospectively. Results The causes of readmission were residual prostatic hyperplasia for 32 patients (31.37%),bladder neck restriction for 22 patients (21.57%),urethral stricture for 18 patients (17.65%),hematuria for 15 patients (14.71%),epididymitis for 6 patients (5.88%),urinary tract infection for 4 patients (3.92%),carcinoma of prostate for 3 patients (2.94%),and neuropathic bladder dysfunction for 2 patients (1.96%). All patients were satisfied with their therapeutic efficacy after different treatments. Conclusion The main complications after TURP include residual prostatic hyperplasia,bladder neck restriction,urethral stricture and hematuria. Best therapeutic approach should be chosen according to different causes of the late complications after TURP.

Objective To study the expression of VEGF-C and its receptor in breast carcinoma tissue and in peritumoral tissue,as well as their clinic significance.Methods Immunohistochemistry SP method was used to examine the expression of VEGF-C and VEGFR3 in 70 cases of breast cancer and in its peritu- moral tissue.Results In all 70 cases of breast cancer,the positive expression rate of VEGF-C in breast car- cinoma tissue was 78.6 %,and its rate in peritumoral tissue was 54.3 %.There was a significant stastistic dif- ference between the two groups(P

OBJECTIVETo observe the therapeutic effect of shengxuening (SXN) in treating iron-deficiency anemia (IDA) and to explore its molecular mechanism on iron metabolism balance regulation.

METHODSPatients with IDA were randomly divided into the treated group and the control group, 50 in each group. They were treated with SXN (0.1 g, three times per day) and ferrous gluconate (0.1 g, three times per day) respectively, for 30 days. Levels of serum iron (Fe), total iron binding capacity (TIBC), transferrin saturation (TS), serum ferritin (SF), transferrin (Tf), soluble transferrin receptor (sTfR) and blood routine test, as well as scoring of TCM qi-blood deficiency Syndrome were conducted before and after treatment.

RESULTSThe total effective rate in the treated group reached 92%, it was shown that SXN could improve the iron metabolism, increase levels of Fe, TS, SF and reduce levels of TIBC, Tf, sTfR, it has obvious effect in promoting erythrocyte generation and could promote formation of leucocytes and platelets. The total effective rate in the control group was 32%, which was significantly lower than that in the treated group (P < 0.01).

CONCLUSIONThe effect of SXN in treating IDA and qi-blood deficiency Syndrome is evident, it could improve the iron metabolism, increase levels of Fe, TS, SF and lower levels of TIBC, Tf, sTfR.

OBJECTIVEThe association of metabolic syndrome (MetS) with cardiovascular diseases (CVD) has not been adequately explored in middle-aged and elderly Chinese. This study aimed to investigate MetS' prevalence and its impact on the CVD incidence in this specific population group.

METHODSA data set of a community-based prospective cohort study was analyzed. A total of 2300 subjects aged 40-94 years were followed up for the CVD events. MetS defined according to the JCDCG criteria was assessed at baseline, and the middle-aged and elderly groups were classified by the WHO definition.

RESULTSAs compared with the middle-aged group, the prevalence of MetS increased by 0.6 times (34.6% vs. 21.3%) and the incidence density of CVD increased by 4.9 times in the elderly group (52.3/1000 person-year vs. 8.9/1000 person-year). Furthermore, the multivariate Cox regression revealed that the risk to CVD incidence was independently related to increased waist circumference in the middle-aged group (HR=2.23, P<0.01) and to elevated blood glucose in the elderly group (HR=1.39, P<0.01).

CONCLUSIONMetS was highly prevalent in middle-aged and elderly Chinese. MetS significantly increased the risk to CVD incidence in the elderly. All individuals with metabolic disorders should receive active clinical care to reduce the incidence of CVD.

OBJECTIVETo study the biological properties of human dental pulp cells (HDPC) by cloning and analysis of genes differentially expressed in HDPC in comparison with human gingival fibroblasts (HGF).

METHODSHDPC and HGF were cultured and identified by immunocytochemistry. HPDC and HGF subtractive cDNA library was established by PCR-based modified subtractive hybridization, genes differentially expressed by HPDC were cloned, sequenced and compared to find homogeneous sequence in GenBank by BLAST.

RESULTSCloning and sequencing analysis indicate 12 genes differentially expressed were obtained, in which two were unknown genes. Among the 10 known genes, 4 were related to signal transduction, 2 were related to trans-membrane transportation (both cell membrane and nuclear membrane), and 2 were related to RNA splicing mechanisms.

CONCLUSIONThe biological properties of HPDC are determined by the differential expression of some genes and the growth and differentiation of HPDC are associated to the dynamic protein synthesis and secretion activities of the cell.

OBJECTIVETo investigate the function of VEGF pathway in promoting angiogenesis with Xuefu Zhuyu Tang (XFZYT).

METHODSerum pharmacology technique was adopted to treat endothelial cells ECV304 with XFZYD containing serum and blank serum with concentrations of 1.25%, 2.5% and 5%. Methyl thiazolyl tetrazolium (MTT) assay, boyden chamber migration assay and in vitro vessel formation assay were used to test endothelial cell proliferation, migration and angiogenesis capacities. ELISA, immunohistochemistry and RT-PCR were used to detect secretion and expression of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor-2 (VEGFR2).

RESULTXFZYT-CS with a concentration of 1.25% only affected angiogenesis capacity in vitro. XFZYT-CS with a concentration of 2. 5% promoted cell proliferation, migration and angiogenesis capacities and significantly increased VEGF level and VEGF/VEGFR2 expressions. XFZYT-CS with a concentration of 5% only up-regulated intracellular VEGF expression and thereby improving endothelial cell proliferation, migration and angiogenesis.

CONCLUSIONXFZYT can induce endothelial cell proliferation, migration and angiogenesis by up-regulating VEGF-VEGFR2 pathway, which partially proves its angiogenesis effects.

Objective To compare the effectiveness of ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy in treatment of bladder calculi. Methods Clinical data of 76 cases of bladder calculi patients were collected from January 2013 to December 2015. All the patients were randomly divided into two groups: Group A was performed by ureteroscopic lithotripsy via urethral Peel-away sheath (n = 45). Group B was transurethral ureteroscopic lithotripsy (n = 31). Results 76 cases of bladder calculi were successfully treated by one-time lithotripsy. Lithotripsy time: group A was (17.8 ± 5.9) min, group B was (22.7 ± 8.3) min (t = 2.96, P = 0.004); stone clearance time: group A (12.6 ± 4.9) min, group B (24.5 ± 5.3) min (t = 9.90, P = 0.000);Intraoperative urethral mucosa injury : group A (1.0 ± 0.5), group B (2.1 ± 0.4) (t = 9.47, P = 0.000); VAS score:group A (1.9 ± 0.6), group B (2.6 ± 0.6) points (t = 4.72, P = 0.000); indwelling catheter time: group A (1.0 ± 0.2) d, B group (1.4 ± 0.9) d (t = 2.59, P = 0.012); There was no significant difference in hospitalization expense, group A was (7437.4 ± 356.7), group B was (7296.8 ± 333.8) (t = -1.73, P = 0.087). There were no complications such as hemorrhage, perforation and rupture of the 2 groups, without convertion to open surgery either. After the treatment of oral antibiotic, 1 case of postoperative urinary tract infection was cured in group B. In our study, case of postoperative urinary retention was 1 in group A, versus 5 in group B, with statistical difference (χ2 = 6.43, P = 0.011). Follow up: 13 patients were lost to follow-up, the other patients were followed up for 6 ~ 12 months. There was 1 case of elderly male patient with urinary retention due to BPH in each of the 2 groups, the other patients had no recurrence of calculus. By analyzing the statistical results, it was found that the experimental group had obvious advantages over the control group in the lithotripsy time, stone clearance time, urethral mucosa injury, postoperative pain and postoperative indwelling catheter time. Conclusion There is no significant difference in efficacy of the treatment of bladder calculi between ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy. However, our study shows the Peel-away ureteroscopy has the advantages of shorter lithotripsy time, shorter time of stone clearance and less injury of urethra mucosa menbrane, there was no significant difference in operation cost between two groups. Therefore, Ureteroscopic via urethral Peel-away sheath is an effective method for endoscopic bladder lithotripsy.

Objective To compare the lung volume before and after the operation for the treatment of chronic empyema with CT 3-dimensional imaging,and to evaluate its role in the assessment of pulmonary function. Methods A total of 78 patients with chronic empyema from 2000 to 2016 in our hospital were enrolled in this study.The patients were divided into two groups according to the operational styles,with 47 cases in the decortication group and 31 cases in the catheter drainage group respectively.Reformation of the chest CT data was used to determine the lung volumes and the routine pulmonary function tests(PFT)were performed before and after the operation. The lung volumes and the PFT results before and after the operation were compared between the two groups with t test. Then multiple linear regression analysis was applied to test the relationship between the lung volumes and the values of PFT after the operation. Results The mean lung volume of catheter drainage group was(1 548±467)cm3,while it was(1 418±802) cm3for the decortication group preoperatively(t=1.665,P=0.07).After the operation,the mean lung volume of decortication group was(2 677±815)cm3,while it was(2 169±185)cm3for the catheter drainage group. There was statistically significant difference for the increase of lung volume between the two groups after operation(t=2.371,P<0.05).There was no significant difference between the two groups before the operation for the values of the PFT(t=1.467 to 1.874,P>0.05). After the operation, the values of the PFT in the decortication group were higher than those in the catheter drainage group(t=1.990 to 2.799, P<0.05). The changes of postoperative lung volume were positively correlated with the values of the PFT(β=0.312 to 0.701,P<0.05). Conclusions Decortication has a better effect on the lung volume and the pulmonary function for patients suffered from chronic empyema. CT modeling (3-dimensional-imaging) is an effective method for evaluating the pulmonary function of postoperative lung according to the lung volume measurement.
