Objective To investigate the clinical value of knee joint infection indexes of white blood cell (WBC),C reactive protein (CRP),erythrocyte sedimentation rate (ESR) and procalcitonin (PCT),interleukin-6 (IL-6) and absolute value of neutrophil (GR).Methods One hundred and twelve cases of preoperative knee joint infection in our hospital from June 2010 to March 2015 were selected as the research group and contemporaneous 112 cases of no preoperative and postoperative knee joint infection were selected as the control group.The venous blood was collected for observing the changes of the above indexes before operation and at postoperative 1,3,5,7,14 d.Results The levels of WBC,CRP,ESR,PCT,IL-6 and GR before operation and at postoperative 1d in the study group were significantly higher than those in the control group (P<0.05);the levels of WBC,CRP,PCT and IL-6 at postoperative 3 d in the study group were significantly higher than those in the control group (P<0.05);the levels of WBC,CRP,ESR and IL-6 at postoperative 5 d in the study group were significantly higher than those in the control group (P<0.05);the difference at the other time points between the two groups was not statistically significant (P>0.05);in the Logistic regression analysis,the six indicators of WBC,CRP,ESR,PCT,IL-6 and GR6 all could predict knee joint infection (P=0.005,0.004,0.000,0.002,0.003,0.007).Conclusion WBC,CRP,ESR,PCT,IL-6 and GR have certain value for early diagnosis and prevention of infection,and further study on expanded sample size cn carry on.

Objective To discuss the diagnostic and therapeutic value of duodenoscopy for chronic pancreatitis. Methods A total of 67 patients with chronic pancreatitis were treated with duodenoscopy in our hospital from January 2000 to December 2006. Among the patients, 19 patients who had duodenal papilla stenosis without obvious dilation of the pancreatic duct were treated with EST; 48 patients who had dilation of the pancreatic duct underwent EST combined with EPS. ERBD was performed on 21 patients who had stenosis of the inferior segment of the common bile duct, among which 12 received insertions of two stents into the biliary pancreatic duct. In 27 patients with stones in the pancreatic duct, the stenotic segment of the pancreatic duct was dilated after EPS, and then the stones were removed using basket or balloon. Afterwards, ERPD was performed if necessary. These patients were followed up with ERCP every 3 months, stents were used if necessary. Results Duodenoscopy was completed in 62 of the 67 patients with a success rate of 92.5% (62/67). Abdominal pain disappeared or markedly relieved in 60 cases after the treatment showing an effective rate of 96.8% (60/62). The operation was ineffective in 2 patient, who had no relief of their abdominal pain. The failure of stent insertion was due to the multiple stenosis of the pancreatic duct. Abdominal pain was markedly relieved in 21 patients who received ERBD and 38 patients who underwent ERPD. During a 39.5-month follow-up (5-70 months), no recurrence of the symptom was found. In the 27 patients with stones in the pancreatic duct, the stones were removed in 19 patients. After the treatment, 15 patients developed transient hyperamylasemia, 5 had acute pancreatitis, 3 had hemorrhage. No perforation, conversion to an open surgery, or death occurred in this series. Conclusions Duodenoscopy, which is safe, effective, and minimally invasive, is the first choice for chronic pancreatitis. The treatment outcomes can be improved by combining duodenoscopy with other therapies.

Objective To study the clinical and pathologic features,and endoscopic diagnosis as well as therapy and prognosis of the primary gastrointrestinal lymphoma(PGIL), and to improve its diagnosis and therapy efficiency. Methods The clinical data in 29 cases of PGIL were retrospectively reviewed. Results In these cases, the tumor was mainly located at stomach (n=21), colon(n=6) and small intestine(n=2). The type of pathology was mucosa associated lymphoid tissue lymphoma(n=8), diffuse large B-cell lymphoma(n=18), T-cell lymphoma(n=3). The commom manifestation include abdominal pain, anaemia, abdominal distention, melena or hemafecia, loss of weigh etc. The tumor appeared infilitrative in 11 cases, ulcerative in 10 cases, protruding in 6 cases, 9 cases were diagnosed by firstly routine biopsy endoscopiccally. 10 cases were treated by operation and chemotherapy, 19 cases were treated by chemotherapy. Up to now, 6 cases survival in operation group, 13 cases survival in chemotherapy group, the difference was not statistically significant . Conclusions PGIL was mainly located at stomach, which was not specific clinical manifestation; The type of pathology was mainly diffuse large B-cell lymphoma; the diagnositic rate of routine endoscopic biopsy was low. chemotherapy was the first treatment of PGIL.

Objective To assess the diagnostic value and safety of push enteroscopy in intestinal diseases. Methods From March.1998 to December 2006,345 patients were examined by push enteroscopy.Results The enteroscope bypassed the Treize ligament in 318 cases, The average examination spend 30 minutes. 144 patients were diagnosed intestinal diseases, the detection rate was 41.74%. 28 patients underwent endoscopic haemostasis treatment, 13 patients received endoscopic polypectomy. No complication of perforate, hemorrhage, abdominal pain occurred. Conclusions Push enteroscopy is an efective and safe method for diagnosing intestinal diseases, and could undertook corresponding therapy.

Objective To investigate the prevalence of H.Pylori infection and antibiotic resistance in patients with peptic ulcer.Methods A retrospective analysis of 429 endoscopy and H.Pylori culture results in the First People's Hospital of Hangzhou from 2012 to 2013 was conducted.The rate of H.Pylori infection in patients with peptic ulcer, and the resistance rates of H.Pylori to metronidazole, levofloxacin, clarithromycin,amoxicillin, gentamicin, furazolidone were analysed.Results The positive rate of H.Pylori in people with peptic ulcer was 53.1％ (228/429).The resistance rates to metronidazole, levofloxacin, clarithromycin,amoxicillin, gentamicin and furazolidone were 94.7％ (216/228), 18.9％ (43/228), 18.9％ (43/228), 0, 0 and 0.Double antibacterial resistant rates of metronidazole and clarithromycin, metronidazole and levofloxacin were 18.0％ (41/228) and 17.1％ (39/228).Triple antibacterial resistant percentage of levofloxacin + metronidazole + clarithromycin was 8.3％ (19/228).The resistance rate of clarithromycin in 43 patients who were also resistant to levofloxacin was 46.5％ (20/43), while the resistance rate of clarithromycin in 185 patients who were also sensitive to levofloxacin was 12.4％ (23/185)with significant difference(x2 =26.480,P =0.000).A positive association between the resistance to levofloxacin and to clarithromycin was found.Conclusion The H.Pylori infection is closely related to the occurrence of peptic ulcer.Without the basis of culture results in patients with H.Pylori positive, amoxicillin, gentamicin and furazolidone could be the first choices in clinical,because of their low resistance rates.Clarithromycin can be used as an alternative.

Objective Experiment the effective method to improve cell injury of cerebral ischemia.MethodMake Mongolirn-Gerbil acute full cerebral ischemia model with ligation of double main carotid arteries,observe the influence of intervening abdomen injection of western medicine Nimodipin and TCM Xingnaojing on MDA and SOD in cerebral tissue of Mongolirn-Gerbil in acute period of ischemia reperfusion.ResultIt finds that Nimodipin and Xingnaojing both can markedly increase SOD activity and decrease MDA content,there’s no obvious difference between them,while there’s difference among different dosages of Xingnaojing,the effect is rising with dosage increased.ConclusionAs a Chinese drug of anti-free radical injury,Xingnaojing has similiar effect with Nimodipin.

Objective To explore the effects of Xiefuzhuyu decoction on myocardial cellar apoptosis and expression of ICAM-1 gene protein in rats of experimental acute ischemic myocardium. Methods The left anterior descending coronary artery was ligated to make a model of acute ischemic myocardium. The changes in myocardial cellar apoptosis and the ICAM-1 gene expression were detected. Results The number of myocardium cellar apoptosis in Xiefuzhuyu group and Diaoxinxiekang group were significantly less than those of ischemic model group respectively. The number of myocyte necrotic cell increased in ischemic group. At the same time, the expression of ICAM-1 supported this condition. Conclusion Xiefuzhuyu decoction and Diaoxinxiekang can protect ischemic myocardium.

Objective To establish the quality standard of Fengsui Pills.
