Objectives To observe the clinical significance and application value of autologous blood transfusion in neurosurgery of primary hospital. Methods Four hundred and fourteen patients who underwent the neurosurgery operation and were subjected to intraoperative blood transfusion were selected, among whom 97 patients were subjected to autologous blood transfusion (observation group), and 317 patients were subjected to heterogenous blood transfusion (control group). The condition of intraoperative blood transfusion, changes of hemoglobin and hematocrit, blood transfusion related cost were compared between 2 groups. Results There were no statistical differences in operation time, infusion volume, rate of transfusion related complications and postoperation hemoglobin, hematocrit between observation group and control group (P>0.05). The patients in control group were infused with 189 000 ml, and the transfusion liquid volume proportion of total blood transfusion was 79.22%(189 000/238 580);13 patients in observation group were used the heterogenous blood transfusion with 5 400 ml, and the transfusion liquid volume proportion of total blood transfusion was 10.30%(5 400/52 430). Eighty-six patients (88.66%, 86/97) in observation group performed autologous blood collection and transfusion, the volume of autologous collection was 80 650 ml, and the volume of transfusion was 47 020 ml. Eleven patients in observation group did not perform autologous blood transfusion, among whom 6 patients was because of operational and mechanical reasons, and 5 patients performed collection but did not transfuse. The cost of heterogenous concentrated suspension red blood cell over 6 U was significantly higher than the cost of disposable material and injection of autologous blood:(2 287.06 ± 243.52) yuan vs. (1 595.08 ± 133.95) yuan, and there was statistical difference (P<0.05). The rate of heterogenous concentrated suspension red blood cell 6 U in control group was 14.83%(47/317), and the rate of over 6 U was 6.62%(21/317). Conclusions The autologous blood transfusion is safe and effective, and it is worth popularizing in neurosurgery of primary hospital. But in the process of its application, it is necessary to strengthen the user′s operating skills and ensure the quality of autologous blood transfusion.

Purpose To investigate the expression of FABP5 in oligodendroglioma and its clinic pathological significance.Methods Immunostaining of FABP5 and Ki-67 were performed in 87 oligodendrogliomas and 23 paracancerous brain tissues.The relationships between FABP5 expression and Ki-67 expression or clinic pathological parameters were statistically analyzed.Patients were followed up after operation.Results (1) The expression of FABP5 was significantly higher in oligodendroglioma [63.2％ (55/87)] than that in normal control [34.8％ (8/23)].(2)The expression of FABP5 was positively correlated with the histological grade (P =0.018,rs =0.254) and the Ki-67 expression (P =0.003,rs =0.318) in oligodendroglioma.(3) Univariate analysis showed that the expression of FABP5 protein,Ki-67 protein,age and chemotherapy were significant prognostic factors for oligodendroglioma patients.Conclusion FABP5 may play an important role in the pathogenesis and progression of oligodendroglioma,and could be used as a novel biological indicator of disease progress as well as prognosis for oligodendroglioma patients.

Objective:To evaluate the effect of post-conditioning in brain injury induced by myocardial I/R on inflammatory factor and GFAP.Methods:Male Sprague-Dawley rats were randomly allocated into 3 groups (n=8):group Sham,group IR,group IPost.Myocardial IR was induced by occlusion of the anterior descending branch of the left coronary artery for 30 min.group IPost received 3 cycles of 10 s reperfusion followed by 10 s ischemia at the end of myocardial ischemia.The rats were sacrificed at 120 rain of reperfusion and the brains were removed for microscopic examination,inflammatory factors and GFAP.Results:Compared with group Sham,IL-6,IL-8 were significantly increased,IL-10 was down-regulated in group IR(P＜0.01).Post-conditioning can decrease IL-6,IL-8 and up-regulated IL-10(P＜0.01).When compared with group Sham,the expression of GFAP was higher in group IR(P＜0.05),however,the GFAP in group IPost is the most among these three groups(P＜0.01).Conclusion:Post-conditioning could protect brain by decreasing inflammatory factors,increasing GFAP,which both from brain injury induced by myocardial ischemia reperfusion.

OBJECTIVE To investigate the productive rate of AmpC ?-lactamases and ESBLs produced by the Gram-negative bacilli from the nosocomial infection in our hospital. METHODS AmpC ?-lactamases and ESBLs were detected by the improved cefotaxime and ceftriaxone three-dimensional test. RESULTS The productive rate of AmpC ?-lactamases was 16.00%.Among them,the productive rate of AmpC ?-lactamases was only 8.84%.The Enterobacter cloacae,Serratia marcescens and Enterobacter aerogenes were easy to produce the enzymes(36.00%,31.25% and 28.00%).The productive rate of AmpC ?-lactamases and ESBLs at the same time was 7.16%. CONCLUSIONS The productive rate of the enzymes by the Gram-negative bacilli from the nosocomial infection is rather high.

Objective To quantify sjTREC using a modified method in patients who underwent allogeneic hematopoietic stem transplantation (all-HSCT),and determine the level of thymic output function and analyse the influencing factors in post-allo-HSCT patients.Methods Real time quantitative PCR was used to detect sjTREC levels from the peripheral blood DNA of pre-transplantation,14 d,28 d,3 m,6 m,9 m,1 y,1.5 y,2 y,2.5 y,and above 2.5 y after HSCT,and analyse thymic output function and related factors after HSCT.sjTREC levels in 24 normal individuals were also determined to use as the normal range.Results The mean of Log (sjTREC copies/ml) in normal individuals was 3.74±0.26.Negative correlation existed between thte Log sjTREC and the age (r =-0.65,P ＜ 0.01).There was no clear association between the TREC and the gender.Log sjTREC in pre-transplantation patients was 3.09±0.52,and the levels of sjTREC in 14 d,28 d,6 m,1 y after HSCT were 1.18±0.22,2.16±0.31,1.31±0.2,1.83±0.31,respectively.There was no significant difference between normal individuals and patients 1.5 years after HSCT.The post-transplantation level of sjTREC was not related to the age,but was negatively correlated to the acute graft versus host disease (aGVHD) 1 year after HSCT.There was no difference between patients with or without aGVHD 1.5 years post-HSCT.Conclusion The modified method for detecting sjTREC is applicable to allo-HSCT.The recovery of thymic output function after allo-HSCT is slow,in which aGVHD may have a negative effect.

Objective To evaluate the efficacy and safety of different bismuth-based quadruple therapies for Helicobacter pylori (H.pylori) eradication.Methods From December 2012 to October 2013,240 patients with H.pylori infection were collected and evenly divided into clarithromycin group,levofloxacin group,furanzolidone group and metronidazole group.Each group received bismuth potassium citrate 220 mg,esomeprazole 20 mg and amoxicillin 1 000 mg twice daily.In addition,each group received clarithromycin 500 mg,levofloxacin 200 mg,furanzolidone 100 mg,and metronidazole 400 mg,respectively.The course of treatment was 10 days.At least four weeks after the end of therapy and withdrawal the medicine,patients underwent fasting 13C-urea breath test or 14C-urea breath test.The negative result indicated as successful H.pylori eradication.The adverse effects were observed and recorded during treatment.The rate of H.pylori eradication was analyzed by the intention to treat (ITT) analysis and per protocol (PP) analysis.Chi-square test was performed for eradication rate comparison among groups.Results According to ITT analysis,the eradication rate of clarithromycin group,levofloxacin group,furanzolidone group and metronidazole group was 81.67％ (49/60),88.33％ (53/60),93.33％ (56/60) and 73.33％ (44/60),respectively,and according to PP analysis which was 85.96％ (49/57),89.83％ (53/59),94.92％ (56/59) and 75.86％ (44/58),respectively.The differences among four groups were statistically significant (x2 ＝10.13 and 9.89,both P＜0.05).The differences between furanzolidone group and metronidazole group were statistically significant (x2 =8.64 and 8.55,both P＜0.01).There were no statisticaly significant differences in adverse effects among the four groups (x2 =0.47,P＞0.05).Conclusion The H.pylori eradication rate is high in furanzolidone contained bismuth based quadruple therapy and with good safety,which could be the first line treatment for H.pylori eradication.

Objective To investigate the effects of penehyclidine hydrochloride (PHC) on acute lung injury induced by blunt chest trauma-hemorrhagic shock and resuscitation in rats.Methods Forty male SpragueDawley rats,aged 8 weeks,weighing 250-300 g,were randomly assigned into 4 equal groups (n =10 each) using a random number table:sham operation group (S group),blunt chest trauma combined with hemorrhagic shock and resuscitation group (group THSR),PHC for prevention group (group P1)and PHC for treatment group (group P2).ALI was induced by dropping a 300 g weight onto a precordial protective shield to direct the impact force away from the heart and toward the lungs in anesthetized rats in THSR,P1 and P2 groups.Blood was withdrawn via the femoral artery 5 min later until MAP was decreased to 35-45 mmHg within 15 min and maintained at this level for 60 min,followed by resuscitation.In P1 group,PHC 2 mg/kg was injected intravenously at 30 min before blunt chest trauma.In P2 group,PHC 2 mg/kg was injected intravenously at 60 min after hemorrhagic shock.At 6 h after the model was established,arterial blood samples were obtained for blood gas analysis and for measurement of concentrations of interleukin-6 (IL-6) and interleukin-1β (IL-1β) in serum by ELISA.Oxygenation index (OI) was calculated.The animals were sacrificed and bronchoalveolar lavage fluid (BALF) was collected for determination of white blood cell count and protein concentrations.Lungs were removed for examination of pathological changes and ultrastructure and for determination of Toll-like receptor (TLR4) and phosphor-p38 mitogen activated protein kinase (p-p38MAPK) expression (by Western blot).Results Compared with group S,PaO2 and OI were significantly decreased,PaCO2,protein concentrations in BALF,white blood cell count,and IL-6 and IL-1β concentrations in serum were increased,and TLR4 and p-p38MAPK expression was up-regulated in THSR,P1 and P2 groups.Compared with group THSR,PaO2 and OI were significantly increased,PaCO2,protein concentrations in BALF,white blood cell count,and IL-6 and IL-lβ concentrations in serum were decreased,TLR4 and p-p38MAPK expression was down-regulated in P1 and P2 groups.No significant differences were found in the parameters mentioned above between P1 and P2 groups.Conclusion PHC can mitigate acute lung injury induced by blunt chest trauma-hemorrhagic shock and resuscitation in rats,and inhibited activation of TLR4/ p38MAPK signaling pathway and attenuated inflammatory responses are involved in the mechanism.
