Objective:To investigate the use of antibacterial drugs during the perioperative period of a cesarean section and observe the differences before and after antibacterial drug remediation. Methods:1 569 cesarean cases from 2010 to 2012 were investigated, and the use of antibacterial drugs, drug categories, drug combinations, medical expenses, and so on was statistically analyzed with the use of the statistical software SPSS13. 0. Results:The rate of antibacterial drug usage within the 1 569 cesarean cases was 100%;for pre-operative antibacterial drug remediation, azithromycin, cefathiamidine, and ornidazole were the top three, while the top three antibacterial drugs for post-oper-ative remediation were arecefathiamidine, cefuroxime, and clindamycin. There was no significant difference between the two groups of incision infections, and the rate for combined use of drugs dropped. The analysis of drug costs is of statistical significance. Conclusion:The analysis of antibacterial drug remediation is useful for the rational use of anti-bacterial drugs and a reduction of costs.

ObjectivePresent treatment in plastic surgery on giant congenital melanocytic nevus has always been a tough practice because it is difficult to achieve balance between effects and costs of treatment.This paper aimed to explore the concrete procedure of tangential excision and dermabrasion in treatment of adult giant congenital melanocytic nevus. Methods Taking into consideration pathological examination results before surgery,diseased regions,psychological expectancy and other factors,we used a humby knife or globe grinding head to remove giant congenital relanocytic nevus by wiping off the surface of it in 10 cases.After operation,the operated area of the skin underwent a process of healing in a moisturized state.In each case,surgical procedure was carried out by 1 2 sta ges,with the interval period ranges from 3 months to 6 months.ResultsOne to 3 years follow-ups showed that among those cases,5 cases obtained good results in which skin color of surgical area turned to normal and pathological examination showed that nevus cells disappeared,4 cases achieved improvement,and 1 case was relapsed.ConclusionsThe two alternative methods for treatment of giant congenital melanocytic nevus,either tangential excision or dermabrasion,with combination of pathological examination results,diseased regions,and psychological expectancy should be taken into consideration,which can remain a maximum balance between effects and costs of treatments.Tangential excision and dermabrasion are effective in some cases of giant congenital nevus where traditional methods do not work,or in order to reduce the cost of body appearance in treatment.Therefore,these two methods deserve to be adopted extensively in clinical therapy.But it still needs further accumulation of experience in practice and longer period of follow-up after operation.

Objective To explore independent risk factors of ventilator associated pneumonia (VAP) on severe craniocerebral injury patients, and propose nursing intervention measures to reduce occurrence of VAP. Methods A retrospective analysis was conducted on 73 severe craniocerebral injury patients with VAP postoperatively from January 2013 to June 2015, and 80 severe craniocerebral injury patients underwent mechanical ventilation without VAP postoperatively at the same time were selected as the control group. Through literature review, questionnaire was designed to collect potential impact factors of VAP in both two groups, the single factor analysis and Logistic regression analysis were applied to explore the VAP independent risk factors, and nursing intervention countermeasures were proposed to improve VAP clinical prevention. Results VAP incidence rate of severe craniocerebral injury patients postoperatively was 23.0%(73/317) , from which 81 strains were detected, the first three strains of strain spectrum were Klebsiella pneumonia (21.0% ), Bauman Acinetobacter (17.3% ) and pseudomonas aeruginosa bacteria (14.8% ). Single factor analysis showed there were significant differences on composition of two groups in age, preoperative Glasgow Coma Scale (GCS) score, operation times, artificial airway type, postoperative mechanical ventilation time, daily airway humidification frequency, daily sputum suction frequency compound injury, daily oral care times (χ2=1.809-11.936, P < 0.01 or 0.05). Logistic regression models showed duration of mechanical ventilation (OR≥7d=3.013; OR≥14d=3.695), secondary surgery (OR =3.111) , preoperative GCS score (OR =2.989), daily airway humidification frequence (OR =2.280), age (OR=2.237) had remarkable influence on occurrence of postoperative VAP (P<0.01 or 0.05). Conclusions The incidence rate of VAP in severe craniocerebral injury patients is higher, age, mechanical ventilation duration, preoperative GCS score, airway humidification degree, second surgery are the independent risk factors of VAP.

Objective To analyze the risk factors for traumatic cerebral venous sinus occlusion (CVSO)and to investigate the strategies of early diagnosis of traumatic CVSO. Methods The clinical data of 212 patients with moderate to severe closed traumatic brain injury from January 2012 to December 2015 were analyzed retrospectively. Logistic regression analysis was used to evaluate the risk factors for traumatic CVSO. Results Of the 212 patients with traumatic brain injury, 16.5%(35/212) patients had CVSO. Ten patients had CVSO of thrombotic type (typeⅠ), 16 patients had CVSO of compression type (typeⅡ), and 9 patients had CVSO of mixed type (typeⅢ). Logistic regression analysis showed that skull fracture (OR = 8.141; 95%CI: 3.224-20.840) and epidural hematoma of crossing venous sinus (OR = 3.179; 95%CI: 1.470-7.037) were the risk factors for CVSO, and the former was more significantly correlated with CVSO. Female gender was the risk factor for CVSO typeⅠ(OR =10.425; 95%CI: 1.831-30.053), epidural hematoma of crossing venous sinus was the risk factor for CVSO typeⅡ(OR = 5.766; 95%CI: 1.885-18.197), and skull fracture, epidural hematoma of crossing venous sinus, and the previous history of vein thrombosis was the risk factors for CVSO type Ⅲ(OR =18.005, 4.596, 11.394; 95%CI: 2.021-58.836, 1.144-19.525, 1.436-46.558). Conclusions In the early diagnosis of traumatic CVSO, the crossing venous sinus fracture line and epidural hematoma should be given attention. Attention should be paid to the history of venous thrombosis. MR venography and CT venography contributes to early diagnosis of CVSO.

In addition to the common complications involving hepatic artery, hepatic vein and biliary tract, which have already been mentioned and discussed in the preceding parts of this article, there are some uncommon complications which have been reported in the medical literature as the case report or as the case- series analysis. This paper sums up these uncommon complications. Part of these uncommon complications can be treated with interventional therapy. It is very important for interventional radiologists to make a further understanding of the different etiology of these uncommon complications occurred after liver transplantation so as to get a comprehensive knowledge about the complications after liver transplantation.

Objectives To investigate the associations of serum superoxide dismutase ( SOD) , malondialdehyde (MDA), and uric acid (UA) with blood pressure and the prevalence of hypertension in a Chinese population. Methods We measured serum superoxide dismutase (SOD), malondialdehyde (MDA) and uric acid (UA) in 506 randomly selected participants. For database management and statistical analysis, we used the SAS 9.13 Software. Results Compared with normotensive participants, hypertensive patients had significantly lower serum levels of superoxide dismutase activity ( =0.0002), and higher serum levels of malondialdehyde and uric acid ( <0.05) .Univariate analysis indicated that serum superoxide dismutase activity was negatively associated with blood pressure, and serum levels of uric acid (P 0.0001);while serum levels of malondialdehyde was positively associated with blood pressure, and serum levels of uric acid (P 0.05) . There was significant difference in systolic (Ptrend=0.02) and diastolic blood pressure (Ptrend=0.04) between three groups defined by tertiles of serum levels of superoxide dismutase, with a lower blood pressure in the highest tertile than in the lowest tertile. Furthermore, the systolic (Ptrend=0.01) and diastolic blood pressure (Ptrend=0.003) in the highest tertile, which defied by the serum levels of malondialdehyde, were significantly higher than those in the lowest tertile. Conclusions Hypertensive patients have a disturbed oxidative and anti-oxidative balance. Oxidative stress may play a role in the pathogenesis of hypertension in Chinese.

Objective To detect the expression of CRF and CRF receptors in colonic mucosa of DSS induced colitis in mice model and to study the effect of CRF and CRF receptors on the development.Methods Six to eight weeks healthy female BALB/c mice were divided into control group and DSS group.Setting up DSS colitis model and colitis was evaluated by the disease activity index(DAI) and histological score.The immunofluorescence technique was used to assay the CRF1 and CRF2 receptors expression in colonic mucosa.The expression of CRF and CRF receptors protein were analyzed by western blotting.Results DSS colitis was set up successfully with significant inflammation in colonic mucosa by the disease activity index (DAI) and histological score.Immunofluorescenee staining evidenced that expression of CRF1 receptor in DSS colitis group has no significant deviation compared to control group(P ＞ 0.05),while the expression of CRF2 receptor was elevated in DSS colitis group compared to control group (P ＜ 0.05).CRF2 receptor was localized in epithelial cells and mononuclear cells in the lamina propria.The levels of CRF and CRF2 receptor protein by western blotting were higher in in DSS colitis group compared to control group (P ＜ 0.05).The level of CRF1 receptor protein in DSS colitis group had no significant deviation compared to control group(P ＞ 0.05).Conclusion The higher expression of CRF and CRF2 in colonic mucosa of DSS colitis may participate in the development of colitis.

Objective To investigate the retinal toxicity and verify the safe dose of intravitreal injection of nonsteroid anti inflamatory drug, diclofenac sodium. Methods Twenty eight healthy adult white rabbits were divided at random into 7 groups and received in every right eye the intravitreal injection of a single dose of diclofenac sodium solution ranging from 0.4～1.0 mg/0.1ml respectively,the left eyes were regarded as control ones. Before injection and on the 1st, 3rd, 7th, 14th, 21st, and 28th day after injection the electroretinography on both eyes was examined. On the 28th day after injection the retinas of two rabbits of every group were examined by using light microscopy. On the 10th and 30th day after injection the retinal tissues around the optic nerve disk of two eyes from every group at random were tested by using transmission electron microscopy. Results The ratio of amplitude of b wave of electroretinography in 0.4 mg and 0 5 mg groups had no significant difference from groups before injection,the retinal tissues showed no structural changes in light and electron microscopy examination. The ratio of amplitude of b wave of photoptic electroretinography in 0.6 mg groups in the early stage after injection was markedly reduced ( P
