Proinflammatory cytokines induced by peripheral immune challenge can activate the inflammatory reflex, which results in negative-feedback control of inflammation .Some recent studies revealed that it is the splanchnic nerve , not the vagus nerve , to constitute the efferent arm of the inflammatory reflex .Further researches are needed to iden-tify the neural construction and regulatory mechanism of the inflammatory reflex , which might be harnessed for the treatment of inflammation and the development of anti-inflammatory drugs .

Objective To evaluate the levels of neutrophil gelatinase associated lipocalin (NGAL) in prediction of acute kidney injury (AKI) in children with burn. Methods Forty seven children with burn were selected in this study and thirty healthy children were enrolled as a control group. Levels of blood routine, urine routine, serum creatinine (Scr), serum NGAL (SNGAL), urine NGAL (UNGAL), blood urea nitrogen (BUN) and C-reactive protein (CRP) were measured. Receiver operating characteristic (ROC) curve were used to estimate the AKI diagnostic value of serum NGAL, urine NGAL and Scr. Results On the day of admission, serum NGAL and urine NGAL were significantly increased in patients with AKI , while Scr did not change significantly as compared with those in non-AKI patients and the healthy controls. In AKI group, serum NGAL and urine NGAL were positively correlated with WBC and CRP on the day of admission , and positively related with Scr on the seventh day. ROC analysis showed the AUC of serum NGAL, urine NGAL and Scr on admission were 0.737(95%CI: 0.653 ~ 0.779, P < 0.05), 0.772(95%CI: 0.632 ~ 0.793, P < 0.05), and 0.508(95%CI: 0.454~0.618, P < 0.05) respectively. The cut-off value of serum NGAL and urine NGAL were 318 μg/L (sensitivity of 72.8% and specificity of 81.6%) and 105 μg/L (sensitivity of 75.6% and specificity of 83.7%). Conclusions Elevation in levels of serum NGAL and urine NGAL occurs earlier than that in Scr level in children with burn. Both serum and urine NGAL level can be used as a biomarker for early prediction of AKI.

Objective To explore the efficacy of treatment for locally recurrent rectal cancer after radical surgery. Methods In this study,the management of 107 patients with postoperative locally recurrence of rectal carcinoma admitted from August 1993 to February 2002 was retrospectively analyzed.Results Thirty-two cases were treated by reoperation combined with adjuvant therapy(group A),37 cases underwent ressction alone(group B),38 patients received adjuvant therapy alone(group C).The age of these patients was 49.3±20.7,44.4±25.4,and 52.9±29.1 respectively.The median survival time after treatment was 27.8,14.6,and 13.7 months,respectively.The five year's survival of patients in group A was better than that in group B and group C significantly(P＜0.05).Conclusions The aggressive surgery combined with adjuvant therapy improves the survival of the patients with locally recurrent rectal cancer after radical surgery.

Acute promyelocytic leukemia (APL) is a special subtype of acute myeloid leukemia, characterized by the reciprocal chromosomal translocation of t (15;17)(q22;q21), which generates PML-RARαfusion protein. All-trans-retinoic acid (ATRA) and As2O3 could induce APL cells to differentiation and apoptosis, respectively, making APL become the first curable leukemia. Autophagy is one of metabolic mechanisms to maintain cell homeostasis. Recent studies have showed that autophagy plays an important role in the differentiation of APL cells induced by ATRA/As2O3. Meanwhile, autophagy may affect the sensitivity of APL cells to the pro-apoptotic effect of drugs. Therefore, targeting and regulating autophagy might be a new therapeutic approach of APL and even other leukemia in the future. This article will briefly review the advance of autophagy in APL in recent years.

Objective To explore the efficacy of various retreatment for locally recurrent rectal cancer after radical surgery. Methods Totally 107 patients of locally recurrent rectal cancer, who were admitted from August, 1993 to February, 2002 and retreated, were retrospectively analyzed. Results Thirty-two patients were treated by resection combined with adjuvant therapy (group A), 37 patients underwent resection alone (group B), and 38 patients received adjuvant therapy alone (group C). The medium age of these three groups was 49.3?20.7, 44.4?25.4, 52.9?29.1, respectively. The median survival time of groups A, B, C was 27.8, 14.6, 13.7 months, respectively. The five-year survival rate of group A was significantly higher than that of groups B and C (P

Purpose:To set up a new method to screen hMSH2 gene mutations, to detect hMSH2 gene mutations in gynecologic tumor population and to find molecular biomarkers of tumor. Methods:The basic data and blood samples from 42 gynecologic tumor patients werre collected. The genetic mutations of the sixth exon and seventh exon of hMSH2 gene were investigated by multiple polymerase chain reaction single strand conformation polymorphism (PCR SSCP),followed by DNA sequencing. Results:The successes in setting up the multiple PCR SSCP method made it possible to detect hMSH2 gene mutations more quickly and more economically. Two samples of the seventh exon mutation was detected in the tumor population. The mutation is Leu→Phe missense mutation. No mutation of the sixth exon was detected by SSCP.Conclusions:The multiple PCR SSCP method is effective in detecting genetic mutations. There is a mutation site in the seventh exon of hMSH2 gene. It is probably a biomarker of gynecologic tumor. This discovery might offer the basis for further investigation of mutations in large amount population and studies of the function of the mutation.

Objective To observe the outcome of patients with ocular cicatricial pemphigoid (OCP) after amniotic membrane grafting or penetrating keratoplasty.Design Retrospective,noncomparative case series.Participants 3 consecutive OCP patients (4 eyes),were included.Methods For 3 patients (4 eyes) in this study,preoperative visual acuity was from HM/5 cm to HM/10 cm.The symblepharon (gradeⅢ) of 2 patients (3 eyes) were detached and amniotic membrane was transplanted,and bandage contact lens were used till 2 months after operations.The other patient (1 eye) was undergone penetrating keratoplasty with glycerol-cryopreserved cornea because of corneal ulcer and perforation.Main Outcome Measures Visual acuity,recovering of conjunctiva and cornea.Results Am- niotic membrane dissolved about 1 month after operation in 2 patients (3 eyes).Symblepharon changed from gradeⅢto gradeⅡ,visual acuity increased to 0.04-0.05,central corneal epithelium was regenerated significantly,and a little new vessel appeared at corneal lim- bus in 2 patients (2 eyes).The graft deliquesced in the patient with penetrating keratoplasty at 20 days after operation and undergone penetrating keratoplasty again after 1 month.In this patient,the graft molten induced the ocular contents run-off and became eyeball at- rophy eventually.Conclusion Our small sample study shows that the symblepharon detachment and amniotic membrane transplantation is effective for improving visual acuity in OCP with ocular surface dysfunction.However,because of various factors,penetrating kerato- plasty is ineffective for OCP with perforating corneal ulcer.

The controversial results of several studies suggest that certain everyday-use chemicals may be linked to breast cancer. ln recent years, extensive researches have been carried out to under-stand breast carcinogenesis and the hedgehog(Hh) signaling pathway has emerged as a critical determi-nant of human breast cancer. Aberrant Hh signaling in adults results in carcinogenesis, angiogenesis, and metastasis. This review is focused on the Hh signaling pathway and chemicals in the regulation of breast cancer development and provide an updated survey of pre-clinical and clinical trials of novel strategies to target them.

Objective To estimate the prevalence of iron deficiency and its influencing factors in 6 to 12-month-old infants,then more effective community nursing intervention of prevention against iron deficiency can be made.Methods Three hundred and thirty-one 6 to 12-month-old infants had been enrolled by convenience sampling method to complete the investigation.Variables associated with iron deficiency in bivariate analysis were evaluated in Logistic regression models.Results The prevalence rates of iron deficiency in 6 to 12-month-old infants was 34.74％.Anemia,age,feeding patterns and zinc deficiency were independently associated with increased risk for iron deficiency.Conclusions Iron deficiency was common and associated with anemia,low age,feeding patterns and zinc deficiency in a certain community in Tianjin.So effective nursing measures must be made to reduce the prevalence rates of iron deficiency in 6 to 12-month-old infants.
