Objective To investigate the clinical characteristics and risk factors of bacterial liver abscess (BLA) complicated with septicemia.Methods Fifty two BLA patients complicated with septicemia admitted in our hospital from January 2011 to December 2015 were retrospectively reviewed;and 52 cases of BLA without septicemia admitted at the same period were randomly selected as control group.The clinical manifestations, laboratory and radiographic findings, clinical outcome of these patients were analyzed.Logistic regression analysis was used to study the clinical features and risk factors of BLA complicated with septicemia.Results Compared to the control group, the BLA with septicemia group had higher prevalence rates in diabetes mellitus, malignant tumors, jaundice, albumin <35 g/L, BUN≥8.2 mmol/L, hyperglycemia, multiple abscesses and abscesses size ≥10 cm(P<0.05 or <0.01).The blood culture showed that K.pneumoniae(63.3%) was the most commonly isolated pathogen, followed by E.coli(16.7%).Univariate analysis revealed that diabetes mellitus(OR=2.200,95%CI 1.042-4.646), malignant tumors (OR=3.667,95%CI 1.023-13.143), albumin <35 g/ L(OR=2.800,95%CI 1.009-7.774), BUN≥8.2 mmol/L(OR=3.167,95%CI 1.265-7.929), hyperglycemia(OR=3.400,95%CI 1.254-9.216), multiple abscesses(OR=2.667,95%CI 1.043-6.815), abscesses size≥10 cm (OR=5.000,95%CI 1.096-22.820) were positively associated with bacterial liver abscess complicated with septicemia.Multivariate Logistic regression showed that abscesses size≥10 cm (OR=14.016,95%CI 1.354-145.070) was an independent risk factor for complication of with septicemia.Conclusion septicemia is a common complication for bacterial liver abscess, clinically effective measures shauld be taken to prevent and control risk factors associated with septicemia.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.
METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.
RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.
CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

This research was to study the regulation of intravenous administration of human umbilical cord blood mesenchymal stem cells (HUCBMSCs) on secretion of neural specific protein in rats after traumatic brain injury (TBI), and to explore its mechanisms promoting the recovery of neurological function. The TBI models of rats were established. We then injected HUCBMSCs, labelled by Brdu (5-bromo-2-deoxyuridine), into the TBI rats via the tail vein using modified Feeney free-falling method. The levels of neural biochemical indicators (serum S100β protein, NSE, LDH, CK) of rats were detected in shamed group, injury group and HUCBMSCs-transplanted group. And the morphological changes of brain tissue of rats in the three groups were observed by using HE staining under light microscope. During the whole experiment no immunosuppressant was used for the four groups. From the research, transplant-related death of the rats was not found in transplantation group. In the injury group, rises were found in contents of serum S100β protein, NSE, LDH, CK in the early stage after the rats were injured, which were much higher than those in shamed group at correspondent time point (P < 0.01). In HUCBMSCs-transplanted group, although these biochemistry indexes were found rising for a short period in the early stage, along with the time, these indexes were obviously lower than in those injury group (P < 0.05). Under light microscopy pathological changes of rats in HUCBMSCs-transplanted group were much slighter than those in injury group. It was well concluded that in the situation of no immuno-suppressants, the intravenous-injected HUCBMSCs could reduce the secretion of serum S100β protein, NSE, LDH, CK, promote the repair of tissue injury effectively, and promote the functional recovery of neurons.
