Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.

Objective To evaluate the effect of health education on endemic diseases in Henan province in 2010.Methods According to the requirements of The Education Program for Endemic Diseases Control in 2009 Henan Province,50 counties (districts) of 18 cities with endemic diseases were selected.Referring to the health education questionnaire in the program,knowledge of endemic diseases were asked of pupils and housewives.Intervention effects were evaluated two months after teaching pupils and housewives in counties,towns,villages and schools with the knowledge of endemic diseases and the questionnaire was used.Results Among 50 counties investigated,5523 pupils and 3206 housewives were surveyed in the baseline according to the requirement,and 5417 pupils and 2891 housewives were surveyed for outcome evaluation.The results showed that after this education,pupils' knowledge about endemic diseases increased from 66.31％(10 987/16 569) in the baseline survey to 93.84％(15 250/16 251),the difference have statistical significant(x2 =3877.78,P ＜ 0.01) ; housewives from 67.56％(6133/9078)to 92.67％(8037/8673),the difference have statistical significant(x2 =1736.33,P ＜ 0.01).After the education,the pupils' knowledge about the iodine deficiency disorders,drinking-water-borne fluorosis and arsenic poisning,coal-burning-borne fluorosis increased from 70.15％ (6263/8928),62.29％(4423/7101),42.96％ (185/270),68.52％ (116/270) to 94.19％ (8344/8859),93.05％ (6376/6852),99.63％ (261/270),96.67％ (269/270),the difference have statistical significant (x2 =1749.85,1939.26,211.83,74.43,all P ＜ 0.01),housewives' knowledge about the iodine shortage diseases,drinking-water-borne fluorosis,the endemic fluorine,the arsenic poisoning increased from 73.27％ (3330/4545),62.79％ (2677/4263,30.37％ (85/135),62.96％(41/135) to 93.96％(4228/4500),91.08％(3555/3903),97.04％(123/135),91.11％(131/135),the difference have statistical significant (x2 =751.03,924.65,129.75,30.23,all P ＜ 0.01).Conclusions Health education intervention has a marked effect in increasing the peoples' knowledge of endemic diseases.Therefore health education should be enhanced in the future.

Objective To investigate the safety and feasibility of reoperatively laparoscopic technique in treatment for locally recurrent rectal cancer.Methods The study enrolled 17 patients with locally recurrent rectal cancer between February 2004 and September 2009 from Shanghai Minimally Invasive Surgery Center.The patients were divided into two groups according to their pelvic recurrence types:central recurrence group (n =14) and anterior recurrence group (n =3).Demographic,surgical data and survival outcomes between two groups were compared.Results The outcomes of demographic data between two groups were not different(P＞ 0.05 ).Compared with central recurrence group,anterior recurrence group had longer operating time (P =0.028).However,the differences of operative blood loss,complications,postoperative rehabilitative outcomes and ratio of R0 resction between groups were not significant ( P ＞ 0.05 ).The overall 5- year survival rate of all the patients was 36％.And the median survival time was 42 months without significant difference between two groups (x2 =1.641,P =0.200).Conclusions Reoperatively laparoscopic technique in treatment for locally recurrent rectal cancer is safe and feasible.Selected patients,specialist operation and higer ratio of R0 resection are the key factors conducive to better short-and long-term outcomes.

Objective: To investigate the applied feasibility of scaffold with modified PLA (Polymer of lactic acid) in tissue engineering. Methods:First, we adopted salting-in method to prepare porous foam scaffold. Then, we reconstructed tissue engineering skin by epidermal cells and fibroblasts combined with modified PLA. On the 14th day of cell culturing in vitro, we was a control. Results:The arfificial skin is composed of epidermis and dermis and similar to natural skin in appearance. The skin consists of fibroblasts and keratinocytes, which are in various proliferation and differentiation stages. Fibroblasts and keratinocytes distribute on the surface of polymer of lactic acid (PLA) and the number of fibroblast and keratinocyte increase. Conclusion:Dialdehyde starches (DAS) not only improve the function of PLA but also have good effects on cells. Moreover, it does not affect the growth and the metabolism of the cells. So it is feasible to use modified scaffold to construct tissue engineering skin.

OBJECTIVETo study the surgical reconstruction of unilateral Craniofacial Atrophy and Hypoplasia.

METHODSAccording to the etiological factors and severity of the facial deformities, different methods are employed, including bone framework reconstruction, soft tissue transplantation, orthognathic surgery.

RESULTSFrom September 1998 to August 2004, 42 cases were treated, Include: Hemifacial Microsomia 22 cases, Hemifacial Atrophy 16 cases, unilateral facial hypoplasia due to radiation 4 cases. Miniplate and transplants extrusion occurred on 2 post radiation patients due to poor soft tissue coverage, infection occurred on 1 patient after mandibular ramus reconstruction using autogenous rib and contralateral mandibular outer cortex. The leaving patients recovered well and the facial asymmetry were improved greatly.

CONCLUSIONSFacial asymmetry due to unilateral Craniofacial Atrophy or Hypoplasia is a common and complex condition for surgical management, The surgical plan should be delicated made individually according to the severity of the soft tissue and the underlying bone framework.

OBJECTIVETo investigate the significance of prostate specific antigen (PSA) examination in seminal plasma of infertile patients.

METHODSEighty-five infertile patients were collected randomly. The level of PSA in seminal plasma was detected by ELISA method. The correlations between PSA and several seminal parameters including sperm density, motility and acid phosphatase (ACP) were analyzed.

RESULTSThe PSA, ACP concentrations and sperm motility in 65 cases of abnormal liquefaction patients were obviously lower than those in normal liquefaction patients(P < 0.01). But there were no significant differences in sperm density among the three groups(P > 0.05). PSA levels were significantly correlated with ACP and sperm motility(P < 0.01).

CONCLUSIONSThe seminal PSA in infertile patients is markedly correlated with semen liquefaction. The abnormal quality and quantity of PSA can result in a depression of sperm motility and subinfertility.

OBJECTIVETo investigate the incidence and risk factors of acute kidney injury (AKI) within the first postoperative week after off-pump or on-pump coronary artery bypass (OPCAB or CCAB) surgery.

METHODSConsecutive patients underwent CABG between January 1990 and August 2006 in our institution and had normal serum creatinine (Scr) and estimated creatinine clearance (Ccr) values before operation were retrospectively analyzed. Multivariate logistic regression analysis was performed to identify risk factors for the development of AKI defined as Scr 130 - 199 micromol/L or Ccr 30 - 60 mlxmin(-1)x1.73 m(-2).

RESULTSIncidence of AKI was significantly higher in patients underwent CCAB compared to those underwent OPCAB (63/331 vs. 61/518, P < 0.01). Peak Scr value was seen at 12th hour post OPCAB and 24th hour post CCAB, respectively. The rapid recovering of Scr occurred between 24th hour to 48th hour in patients underwent OPCAB and 48th hour to 72th hour in patients underwent CCAB surgery. Multivariate forward stepwise logistic regression analysis showed that LVEF < 30%, pulse pressure >/= 60 mm Hg (1 mm Hg = 0.133 kPa), peripheral vascular disease, diabetes, emergent procedure, triple-vessel disease, higher body mass index (kg/m(2)), intraoperative and postoperative IABP, NYHA class III or IV and cardiopulmonary bypass were risk factors for the development of postoperative AKI following CABG, while LVEF > 50% and intraoperative and postoperative IABP were associated with lower incidence of AKI (OR < 1).

CONCLUSIONAKI is not a rare complication post OPCAB or CCAB surgery, especially in patients with reduced LVEF, increased pulse pressure, peripheral vascular disease, diabetes, emergent procedure, triple-vessel disease, higher body mass index, intraoperative and postoperative IABP.

BACKGROUNDVoltage-gated K+ channel (Kv) plays a critical role in the modulation of detrusor contraction. This study was conducted to investigate the expressions of Kv2.1 and Kv2.2 in rat bladder with detrusor hyperreflexia (DH).

METHODSThirty adult female Sprague-Dawley rats (200-220 g) were randomly divided into the control group and the experimental group. The experimental group was subjected to spinal cord injury (SCI). In the controls, the surgical procedure was identical with the exception that dura and spinal cord were transected. Four weeks after SCI, in vivo cystometry and mechanical pulling tests of isolated detrusor strips were performed. mRNA was extracted from the detrusors of normal and DH rats for the detection of expression of Kv2.1 and Kv2.2 by RT-PCR. Differences in expression between normal and overactive detrusors were identified by gel imaging.

RESULTSFourteen rats in the experimental group exhibited uninhibited bladder contraction (>8 cmH2O) before voiding after SCI. One rat died from infection. The frequency of DH in the experimental group was significantly different from that in the control group with or without treatment with 4-aminopyridine (4-AP) (P < 0.05), while the amplitude of DH did not change markedly. The rates of variation of the automatic contractile frequency and amplitude were (66.8 +/- 12.4)% and (42.6 +/- 12.6)% respectively in the control group, and (38.4 +/- 9.8)% and (28.0 +/- 4.6)% respectively in the DH group. 4-AP increased the automatic contractile frequency apart from the automatic contractile amplitude in both the control and DH groups (P < 0.05). 4-AP increased the rate of variation of the automatic contractile frequency more markedly in the control group than in the DH group (P < 0.05). Significant expression of Kv2.2 was not detected in bladders in the control group. Compared to the mRNA levels of beta-actin, the mRNA level of Kv2.1 was 1.26 +/- 0.12 in the control group and 0.66 +/- 0.08 in the DH group. SCI significantly reduced the mRNA level of Kv2.1 in rat bladders with DH (P < 0.05).

CONCLUSIONSOur study showed that the mRNA level of Kv2.1 decreased significantly in rat bladder with DH, which was one of the important pathogenetic mechanisms for DH, and suggested that Kv2.1 might be one of the therapeutic targets for bladder overactivity.
