Objective To analyze the compliance of defecation function training of patients with ultra- low rectal cancer after intersphincteric resection and the influencing factors. And therefore to provide theoretical reference for the problems and nursing management of training. Methods The study was a reviewing trial. The enterostomal therapist educated patients with ultra-low rectal cancer after intersphincteric resection. Research used the basic information questionnaire, compliance evaluation of defecation function training, defecation diary and Fecal Incontinence Quality of Life Questionnaire as research instruments. And statistical analysis was used to acquired data. Results The score of the defecation function training compliance was (67.67 ± 5.28) points; Anal function and the fecal incontinence quality of life was in negative correlation with the compliance; At 9 and 12 months, anal function of patients who had good compliance were obviously improved (P < 0.05). Factors such as complications, internal sphincterotomy, operation, degree of education, pathologic stage, payment of medical expenses were related to the compliance (P < 0.05 or 0.01); The correlation analysis demonstrated that the compliance decreased with time. Conclusions The compliance of defecation function training of patients is related to anal function and the fecal incontinence quality of life. A effective training program and follow- up appointment is very important. Nurses should provide psychological counseling and health education for them to boost confidence improve quality of life.

Objective To investigate the influence of low tidal volume (VT ) combined with low level positive end-expiratory pressure(PEEP) on the respiratory function of elderly patients in general anesthesia .Methods 46 elderly patients scheduled for up-per abdominal surgery in our hospital were randomly divided into two groups ,23 cases in each group .The control group received the conventional tidal volume (VT ) ,while the observation group was given low VT combined with 3cm H2 O of PEEP ,both groups were given intermittent positive pressure ventilation (IPPV) .The arterial blood was collected for conducting the blood gas analysis before operation(T0 ) ,at 30 min after anesthetic intubation(T1 ) and 15 min after extubation(T2 ) .The changes of the indexes of PaO2 ,PaCO2 ,Ppeek and A-aDO2 at various time points were compared between the two groups .Results PaO2 at T2 in the observa-tion group was(83 .58 ± 2 .43) mmHg ,which was significantly higher than that in the control group ,while A-aDO2 in the observa-tion group was(21 .50 ± 2 .12) ,which was significantly lower than that in the control group(P<0 .05);Ppeek at T1 in the observa-tion group was(11 .27 ± 1 .22) cm H2O ,which was significantly lower than that in the control group(P<0 .05) .Conclusion The application of low VT combined with low PEEP in general anesthesia can effectively improve postoperative hypoxemia in elderly pa-tients and is conducive to the respiratory function recovery ,which has better clinical application value .

Objective To investigate the expression of human leucocyte antigen-G (HLA-G) in the endometrium of patients with endometriosis (EM). Methods The expression of HLA-G protein was detected in ovarian endometriosis (OEM) and adenomyosis (AM) using immunohistochemistry method, and the expression of HLA-G mRNA was detected using in situ hybridization technique (ISH), to compare with that in the endometrium of hysteromyoma as the control group. Results The rate of positive HLA-G expression in EM (including AM and OEM) was significantly higher than that in control group (P0.05). The expression of HLA-G protein showed no relation with different clinical phase or different endometrial cycle. Conclusion HLA-G is overexpressed in EM, which may play certain role in the pathogenesis of the disease.

Objective: To measure the glycemic index of foods contained low carbohydratesand discuss the relationship between glycemic index and the amount of fat, carbohydrate, protein and diet fiber from these foods. Methods: According to the method of Wolver,the GIs of these kinds of foods had been determined and caculated by using 25 gram carbohydrates as control because of the low percent(10%)of carbohydrates in foods. Results: The results of GI in 13 kinds of the foods were worked out and there was negative correlation between diet fiber and GI. Conclusions: The inference factors of GI are not the kinds of carbohydrate but the amount of diet fiber in these foods.

Objectives:To observe the relationship between 2 different ways of nasal tube nutrition supplement patterns and clinical patients'endurance and complication. Methods:Self contrast study was used in 8 cases of old patients supplied with nasal tube nutrition for 4 months(perfusion and dripping pattern 2 months each). Biochemical indices and enteric complications before and after nasal tube nutrition were observed. Results:Slowly dripping supplement pattern greatly decreased the incidence of inhalation pneumonia and other complications related with gastro enteric nutrition supplement,such as diarrhea,bloating,vomits and etc.The nutritional status was obviously improved when the continuous dripping supplement pattern was used. Conclusions:Continuous dripping supplement pattern is better than perfusion supplement pattern.

BACKGROUND: Following trauma caused by seawater, cells often exhibit special pathological changes because of the special physico-chemical properties of seawater.OBJECTIVE: To observe corneal histopathological changes and interleukin-6 level in aqueous humor of a rabbit model of penetrating corneal trauma combined with seawater immersion.METHODS: The rabbit eye models of penetrating corneal trauma caused by firecrackers were established in 16 adult healthy grey rabbits. A 3-mm whole-layer incision was made in the cornea. The right eyes served as experimental sides and the left eyes served as controls. Seawater was injected into the aqueous humor of the right eyes via the corneal incision. The eye surface was flushed with seawater for 30 minutes. Physiological saline was used for the left eyes. RESULTS AND CONCLUSION: Optical microscopy results showed that at 1, 2, 3 days after model establishment, corneal cells on the experimental side exhibited severe necrosis and abscission, obvious swelling of substantia propria layer complicated by cellular infiltration. At 1 and 2 days after model establishment, the pathological changes on the control side were the same as the experimental side, but they were mild, but at 3 and 5 days, they were obviously alleviated. At 1, 2, 3 days after model establishment, interleukin-6 level in aqueous humor was significantly higher on the experimental side than on the control side (P < 0.05). These findings suggest that the degree of injury on the experimental side was more severe than that on the control side, indicating that seawater may be an important causative factor of corneal injury.

Objective To investigate the pregnancy opportunity and outcome of patients with sysmetic lupus erythematosus (SLE).Methods We carried out a retrospective analysis of the clinical information of patients who suffered from SLE complicated with pregnancy and were hospitalized to People's Hospital of Peking University from December of 1992 to February of 2012.Chi-square test were used for statistical analysis.Results Forty-nine cases of patients with SLE complicated with pregnancy had 52 pregnancies in total.In 27 cases of planned pregnancies,24 cases(89％ )resulted in live births and 5 cases( 18％ ) had flares during pregnancy.Of the 24 live births,3 cases( 12％)were premature deliveries and 4 cases(17％) had low birth weight infants.In 25 cases of unplanned pregnancies,12 cases (48％) resulted in live births and 20 cases (80％) had flares during pregnancy.Of the 12 live births,6 cases(50％ ) were premature deliveries and 6 cases (50％) were low birth weight infants.The patients in the planned pregnancy group tended to have flares during pregnancy more frequently than those in the unplanned group (P＜0.01),the former were more likely to have live births than the latter (P＜0.01) and were less likely to have premature delivery (P＜0.05).Conclusion Patients with SLE should have planned pregnancy and need collaborative supervision of both rheumatology and immunology department and obstetric department to improve live birth rate,decrease premature delivery and the activity of SLE during pregnancy.

Objective:To evaluate the relationship between intestinal mucosal mast cells and intestinal flora during intestinal ischemia-reperfusion(I/R) in mice.Methods:Forty-eight healthy male C57BL/6 mice, aged 9-12 weeks, weighing 20-25 g, were divided into 4 groups ( n=12 each) using a random number table method: sham operation group (group Sham), sham operation plus mast cell membrane stabilizer cromolyn sodium (CS) group (group Sham+ CS), I/R group and I/R+ CS group.The intestinal I/R injury was induced by clamping the superior mesenteric artery for 45 min followed by 4 h of reperfusion in I/R and I/R+ CS groups.The superior mesenteric artery was only exposed but not occluded in Sham and Sham+ CS groups.CS 50 mg/kg was intraperitoneally injected once a day for two weeks before surgery in Sham+ CS and I/R+ CS groups.The equal volume of normal saline was intraperitoneally injected once a day for two weeks before surgery in Sham and I/R groups.Mice were then sacrificed and intestinal tissues were harvested for examination of the pathological changes of intestinal mucosa with a light microscope after HE staining, and the damage to intestinal tissues was assessed and scored according to Chiu.The expression of mast cell tryptase was detected using the immunohistochemical SP staining method, and the mast cells were counted.The intestinal contents were collected, the total amount of bacteria in intestinal flora was detected by 1% agarose gel electrophoresis, and the diversity (Chao1 index and Shannon index) and relative abundance of intestinal microbial bacteria were detected by 16S rDNA sequencing method. Results:Compared with Sham group, the Chiu′s score and mast cell count were significantly increased, the expression of mast cell tryptase was up-regulated, the total amount of intestinal flora bacteria was increased, Chao1 index and Shannon index were decreased, the relative abundance of Bacteroidetes, Proteobacteria, Bacteroides and Enterobacteriaceae were increased, and the relative abundance of Firmicutes, Lactobacillus and Bifidobacteria was reduced in I/R group ( P<0.05 or 0.01), and no significant change was found in the parameters mentioned above in Sham+ CS group ( P>0.05). Compared with I/R group, the Chiu′s score and mast cell count were significantly decreased, the expression of mast cell tryptase was down-regulated, the total amount of intestinal flora bacteria was decreased, Chao1 index and Shannon index were increased, the relative abundance of Bacteroidetes, Proteobacteria, Bacteroides and Enterobacteriaceae were reduced, and the relative abundance of Firmicutes, Lactobacillus and Bifidobacteria was increased in I/R+ CS group ( P<0.05 or 0.01). Conclusion:The activation of intestinal mucosal mast cell can lead to imbalance of intestinal flora, decrease the number of probiotics and increase the number of potential pathogenic bacteria, and thus be involved in the pathophysiological mechanism of intestinal I/R injury in mice.

Objective To investigate the effects of cefoprazone/sulbactam(CPZ/Sul)and dexamethasone(DXM) on serum IL-8,IL-10 in SD rats with severe pneumonia due to Klebsiella pneumoniae.Methods A rat model of severe pneumonia was induced by intratra- cheal instillation of Klebsiella pneumoniae with a dose of 3.6×108CFU(0.3ml).60 male SD rats were random divided into control group,model group,cefoprazone/sulbactam(CF-L/Sul)group and cefoprazone/sulbactam plus dexamethasone(DXM+CPZ/Sul)group.15 rats in each group were then divided into three subgroups and 5rats in each subgroup were examined at the 6th,8th and 10th day,respectively.Arterial gas analysis.total WBC and PMN cell counts in BALF were examined.ELISA method was used to detect the level of IL-8 and IL-10 in serum.RESULTSIn model group,PaO2 were progressively decreased while total WBC and PMN cell counts in BALF were markedly increased.In CPZ/Sul group,all parameters were alleviated,but there were no significant difference of serum IL-8 and IL-10 between model group and CPZ/Sul group.In DXM+CPZ/SUl group,all parameters were significantly alleviated including serum IL-8 and IL-10.Conclu sions Severe pneumonia of rat due to Klebsiella pneumoniae was characterized by significant elevation of serum IL-8 and IL-10,which suggested the imbalance of inflammatory/anti-inflammatory mediators during the course of severe pneumonia.DXM codd markedly decrease the production of inflammatory mediators and slightly decrease the production of anti-inflammatory mediators,which could restore the balance and contribute to the relief of severe pneumonia.
