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.

PURPOSETraumatic diaphragmatic rupture (TDR) needs early diagnosis and operation. However, the early diagnosis is usually difficult, especially in the patients without diaphragmatic hernia. The objective of this study was to explore the early diagnosis and treatment of TDR.

METHODSData of 256 patients with TDR treated in our department between 1994 and 2013 were analyzed retrospectively regarding to the diagnostic methods, percentage of preoperative judgment, incidence of diaphragmatic hernia, surgical procedures and outcome, etc. Two groups were set up according to the mechanism of injury (blunt or penetrating).

RESULTSOf 256 patients with a mean age of 32.4 years (9-84), 218 were male. The average ISS was 26.9 (13-66); and shock rate was 62.9%. There were 104 blunt injuries and 152 penetrating injuries. Preoperatively diagnostic rate was 90.4% in blunt injuries and 80.3% in penetrating, respectively, P < 0.05. The incidence of diaphragmatic hernia was 94.2% in blunt and 15.1% in penetrating respectively, P < 0.005. Thoracotomy was performed in 62 cases, laparotomy in 153, thoracotomy plus laparotomy in 29, and combined thoraco-laparotomy in 12. Overall mortality rate was 12.5% with the average ISS of 41.8; and it was 21.2% in blunt injuries and 6.6% in penetrating, respectively, P < 0.005. The main causes of death were hemorrhage and sepsis.

CONCLUSIONSDiagnosis of blunt TDR can be easily obtained by radiograph or helical CT scan signs of diaphragmatic hernia. For penetrating TDR without hernia, "offside sign" is helpful as initial assessment. CT scan with coronal/sagittal reconstruction is an accurate technique for diagnosis. All TDR require operation. Penetrating injury has a relatively better prognosis.

OBJECTIVETo discuss the causes, sites, management strategies and curative effects of accidental facial nerve paralysis in the middle ear surgery.

METHODSForty two cases with peripheral facial nerve paralysis following middle ear surgery who underwent surgical exploration and reanimation were analyzed. Facial nerve decompression, primary end-to-end anastomosis, interpositional nerve grafts with the great auricular nerve and nerve substitution of facial-hypoglossal anastomosis were applied to restoration of the facial nerve function. The facial nerve function was graded according to House-Brackmann (HB) Grade.

RESULTSThe most common operation complicating iatrogenic facial nerve injury was mastoidectomy, and the common sites of the injured facial nerve were the tympanic segment and pyramid segment. The facial nerve exploration showed facial nerve edema in nine cases (21.4%), injury of the facial nerve sheath was observed in 10 cases (23.8%), partial nerve fibers transection was found in four cases (9.5%), total nerve fibers transection was detected in 17 cases (40.5%) and two cases (4.8%) with facial nerve anatomical integrity. Facial nerve re-animation methods include facial nerve decompression in 24 cases (57.1%), end-to-end anastomosis in two cases (4.8%), end-to-end anastomosis after nerve transfer in two cases (4.8%), interpositional nerve grafts with the great auricular nerve in 10 cases (23.8%) and facial-hypoglossal nerve anastomosis in four cases (9.5%). The facial nerve function was graded according to House-Brackmann Grade before and after surgery. Twenty eight patients were followed up more than one year. For the 17 cases who received facial nerve decompression, four cases recovered to House-Brackmann Grade I, 11 cases recovered to House-Brackmann Grade II, two cases recovered to House-Brackmann Grade III. For the five cases who underwent the great auricular nerve grafting, three cases recovered to House-Brackmann Grade II, two cases recovered to House-Brackmann Grade III. For the four cases who received facial-hypoglossal nerve anastomosis recovered to House-Brackmann Grade III. For the two cases who underwent the end-to-end anastomosis recovered to House-Brackmann Grade II.

CONCLUSIONSThe tympanic segment and pyramid segment are more vulnerable to be injured during mastoid surgery. The injured facial nerve should be explored and repaired. The methods include facial nerve decompression, end-to-end anastomosis, end-to-end anastomosis after nerve transfer, interpositional nerve grafts with the great auricular nerve and facial-hypoglossal nerve anastomosis.
