OBJECTIVETo explore protective effects of acupuncture at "Zusanli" (ST 36) on cerebral tissue in rats with sepsis.

METHODSCecal ligation and puncture (CLP) was applied to duplicate the rat model of sepsis. According to random number table, thirty SD rats were divided into a sepsis model group (group A), a sepsis model plus electroacupuncture (EA) group (group B), and a sepsis model plus non-acupoint EA group (group C), ten rats in each one. EA with the same frequency and intensity at "Zusanli" (ST 36) and non-acupoint (0.5 cm laterally to "Zusanli") for 30 min was applied in the group B and group C, respectively. No treatment was given in the goup A. 6 hours after CLP, blood was acquired from abdominal aorta to measure the levels of neuron specific enolase (NSE). Then the rats were sacrificed by abdominal aorta exsanguination to take their cerebral tissue for measuring the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6).

RESULTSSix hours after CLP, the level of NSE was (3.51 +/- 0.39) ng/mL in group B, which was significantly lower than (7.72 +/- 0.64) ng/mL in group A (P<0.05). The level of NSE was (8.02 +/- 0.72) ng/mL in the group C, which had no statistical significance with group A (P>0.05). The levels of TNF-alpha, IL-6 in cerebral tissue in group B were significantly lower than that of group A and C (all P>0.05).

CONCLUSIONEA at "Zusanli" (ST 36) has certain protective effect on septic rat's brain, which has some relationship with decreasing levels of cerebral tissue proinflammatory cytokine and plasma NSE. EA at non-acupoint has no the same action.

Objective To explore the clinical characteristics of Henoch-Sch(o)nlein purpura complicated with acute necrotizing acute pancreatitis,in order to provide information for the diagnosis and differentiation of Henoch-Scht(o)nlein purpura complicated with acute abdominal disease.Methods There was a case present with purpura,abdominal pain,massive ascites and poor spirit in Department of Pediatrics,the First Affiliated Hospital of Zhengzhou University.The clinical manifestations and physical examination results were summarized and discussed,some pediatric specialists from nephrology department,surgery department,digestive system department were invited to discuss the case.The treatment was adjusted according to result of discussion,the final diagnosis was tracked.Results The case was firstly diagnosed with Henoch-Sch(o)nlein purpura,acute diffuse peritonitis with cause in dispute.After the discussion,the intestinal necrosis,perforation could not be excluded,acute pancreatitis required further identification.Exploratory laparotomy was received because of the changing condition after discussion.The intraoperative diagnosis was acute necrotizing pancreatitis.The patient recovered well with medical treatment.Conclusion When children with Henoch-Sch(o)nlein purpura had an acute abdominal disease,acute necrotizing pancreatitis should be considered in addition to intestinal necrosis,perforation.

OBJECTIVE To analyze distribution and resistance of bacteria from lower respiratory tract infection in elderly patients,and provide reference for rationl use of agents in clinics.METHODS To collect phlegm specimens from lower respiratory tract infection in elderly patients from Jan 2003 to Jun 2005 in our hospital,to identify pathogens and drug sensitivity test,the results of examination were judged according to NCCLS standard.RESULTS Among 752 pathogens strains,Gram-negative bacteria and Gram-positive cocci were 70.9% and 17.6%,respectively;the most common pathogens of them were Klebsiella pneumoniae(ESBLs 27.7%)14.89%,Pseudomonas aeruginosa 14.36%,Escherichia coli(ESBLs 35.4%)12.77%,Staphylococcus aureus(MRSA 59.0%)11.70%,and fungi 11.57%.CONCLUSIONS The bacteria from lower respiratory tract infection in elderly patients are distributed extensively.In Gram-positive cocci,resistance to vancomycin is not found elsely.Gram-negative bacteria are especially sensitive to imipenem,but with some resistant strains.

An enhanced gold immunochromatographic assay ( GICA ) with simplicity, rapidity and high sensitivity was developed to detect imidaclothiz by using the high affinity between biotin and streptavidin. The 13-nm AuNPs were double-labeled with anti-imidaclothiz antibody and biotinylated DNA, and the 41-nm AuNPs were labeled with streptavidin to prepare an enhanced gold immunochromatographic test strip for imidaclothiz. The working conditions of the strip were systematically optimized, and the sensitivity, specificity, precision and accuracy were assessed by testing the cross-reactivity ( CR) , spiked recovery and validation with high performance liquid chromatography ( HPLC) . Under the optimal conditions, the detection could be completed in 10 min with visual result, and the limit of detection ( LOD ) was 25 ng/mL. The analysis showed no cross-reactivity with analogues of imidaclothiz except for imidacloprid. The detection results of GICA agreed with the spiked concentrations of imidaclothiz at spiked levels of 0 . 05 , 0 . 5 and 5 μg/g in river water, rice, cucumber, tomato, pear, cabbage and apple samples. The detection results of GICA for imidaclothiz in unknown concentration river water and pear samples were consistent with that of HPLC.

Objective To study the effects ofautologous bone marrow mononuclear cells (BMMCs)transplantation during coronary artery bypass gafting (CABG) on myocardial infarct size. Methods Forty myocardial infarction patients diagnosed by coronary angiography (CAG) and SPECT and confirmed at surgery were enrolled and randomly assigned CABG alone (group Ⅰ) or CABG with intramyocardial or intracoronary injection of autologous BMMCs (group Ⅱ), 20 cases in each group. Baseline and followed up evaluations included SPECT and NYHA-FC before and after 6 months operation, recorded the major adverse cardiac events (MACE) at the same time. The number of autologous BMMCs injected was (6.84 ± 2.88) ×107 in group Ⅱ. Results There was no procedure-related complication during 6 months followed up in all patients. After 6 months operation,left ventricular ejection fraction in group Ⅱ was significantly higher than that in group Ⅰ [(57.40 ±5.21)% vs. (50.75 ±5.88)%,t =3.79,P＜0.05],NYHA-FC in group Ⅱ was significantly improved than that in group Ⅰ [(1.30 ± 0.47) grades vs. (1.85 ± 0.59) grades, t = 3.27, P ＜0.05],SPECT showed myocardial infarct size in group Ⅱ was significantly lower than that in group Ⅰ[(14.57 ±5.20)% vs. (20.45 ±5.18)% ,P ＜0.05]. Conclusion Autologous BMMCs transplantation during CABG is safe and feasible, which can reduce the myocardial infarct size in patients with myocardial infarction.

Objective To investigate the effect of ischemia and ischemia/reperfusion(I/R)in rat heart on matrix metalloproteinase-1(MMP-1).Methods The I/R animal models were established by shutting down and reopening the anterior interventricular branch with a silver clamp,then the distribution and amount of MMP-1 of the normal and I/R rat hearts were observed by immunohistochemical staining and Western blotting and analyzed by computer image analysis.Results 1.Immunohistochemical staining showed MMP-1 existed mainly in the cardiac matrix.There were strong positive reactions in fibrocytes,smooth muscle cells of the blood vessel and endotheliaI cells of capillaries.MMP-1 didn't show distinct changes 30 minutes after ischemia,while its concentration increased dramatically 60 minutes after ischemia.The positive reaction of MMP-1 increased 30 minutes after I/R,and 60 minutes after I/R there was large fusion areas in MMP-1 existing reglons.2.Quantitative analysis showed no dramatic changes of MMP-1 after ischemia for 30 minutes(P＞0.05),while dramatic changes were seen 60 minutes after ischemia(P＜0.05).MMP-1 changed dramatically 30 minutes and 60 minutes after I/R.3.Western blotting showed that there were no distinct naked-eye-observable changes.The bands of MMP-1 became widened 30 minutes after I/R,and became obviously widened 60 minutes after I/R.Conclusion 1.MMP-1 is secreted by fibrocytes,smooth muscle cells and endothelial cells of cardiac tissue under physiological conditions,and cardiomyocytes has the potential to secrete MMP-1 under ischemia or I/R.2.The longer time the heart ischemia lasts,the greater MMP-1 concentration will increase.Reperfusion can increase MMP-1 concentration to an even higher level,which may be the main cause of the collagen destruction after heart I/R.

Objective To study the mutation of STK11 gene in a Chinese family and a sporadic patient with Peutz-Jeghers syndrome (PJS),and to provide a basis for genetic diagnosis and counseling.Methods One sporadic patient and two patients from a family with PJS were collected,all of whom had typical mucosal pigmentation and gastrointestinal polyposis.Blood samples were obtained from the two patients and six unaffected relatives in this family,the sporadic patient,and 100 healthy controls.DNA was extracted,and PCR was performed to amplify nine exons and their adjacent introns in the STK11 gene followed by direct sequencing.The sequencing results were aligned to the published sequence of STK11 gene from Genbank.Results No mutation was found in the STK11 gene of any of the patients,unaffected relatives,or healthy controls.Conclusions Genetic heterogeneity exists in Peutz-Jeghers syndrome,hinting that there may be other causative genes or sites for this entity.
