Patient one was a 19-year-old woman of periodic fever with urticaria during the first week of life.And there were typicalfacies,oligoarthritis and central nervous system involvement.She also exhibited a persistent elevation of acute phase reactants.The diagnosis of chronic infantile neurological cutaneous and articular syndrome was made.Short-term dosing of tumor necrosis factor-α receptor antagonist was administrated and was substituted by glucocorticoid and methotrexate.Another two males had an earlyonset of increased acute phase reactants during inflammation attacks.One of them had recurrent fever with urticaria-like rash,arthralgia and headache.Muckle-Wells syndrome was diagnosed on basis of NLRP3 gene mutation (c.92A ＞ T).And another had recurrent urticaria-like rash with conjunctivitis,oligoarthritis,hepatosplenomegaly and increased serum IgD.The clinical diagnosis was mevalonate-kinase deficiency.Autoinflammatory diseases should be suspected by physicians and diagnosed with a combination of phenotype and genotype.Biological agents,especially interleukin-1 antagonist,have broad prospects in the therapy of autoinflammatory diseases.

Objective To investigate whether ?OH radical species present in the acid oxidation-potential water (AOW). Methods Electron paramagnetic resonance spectroscopy (EPR) coupled with the spin trapping technique was used for determination of ?OH radicals. Results A seven-line spectrum characteristic of 5, 5-dimethyl-2-pyrrolidone-N-oxyl (DMPOX) was formed at first, at 60 min the spin adducted DMPO-OH with four-line spectrum characteristic and at 120 min, no spectrum was observed. Conclusion ?OH can be detected in AOW at 60 min and it may come from the interaction of active substance in the AOW.

Objective To stuey effects of coloprotectomy under colonoscopy combined with laparoscope on exfoliated tumor cells in abdominal cavity.Methods 42 cases of colorectal cancer proved by pathologic histology were devided into two groups randomly: Laparoscope Group(laparoscopic surgery) and Combined Group(colonoscopy combined with laparoscope surgery).Operation time,the positive rate of exfoliated tumor cells in abdominal cavity after and before operation,the positive rate of residual tumor cells in resection of operation specimen and postoperative complications between 2 groups were compared.Results Operation time of the Combined Group was shorter than that of the Laparoscope Group [(160.5?12.6) min vs.(201.2?18.4) min,t=-8.363,P=0.000].The positive rate of exfoliated cells in abdominal cavity before operation had no significant difference between the 2 groups[9.5%(2/21) vs.19.0%(4/21),?2=0.194,P=0.659],but the postoperative positive rate of exfoliated cells in the Combined Group was significantly lower than that in the Laparoscope Group[14.3%(3/21) vs.42.9%(9/21),?2=4.200,P=0.040].There were no residual tumor cells in resection of operation specimen of 2 groups.No infection of incisional wound and lung occurred.A follow-up for 6-24 months in the Laparoscope Group showed abdominal metastasis in 1 case.Conclusions Coloprotectomy for colorectal cancer under colonoscopy combined with laparoscope can decrease exfoliated tumor cells in abdominal cavity and shorten operation time.

Objective To investigate the dynamic changes in brain natriuretic peptide (BNP) and the outcome of patients with chronic congestive heart failure (CHF) after the treatment with metoprolol. Methods Sixty-five patients with CHF were admitted to the Forth Affiliated Hospital of Zhengzhou University during April 2004 to April 2007, and they fulfilled the diagnostic criteria of chronic CHF issued by New York Heart Association (NYHA). Of all the patients the left ventricular end-diastolic dimension (LVEDD) ≥65mm. All the patients were randomly assigned into metoprolol group (34 cases) and control group (31 cases), and received conventional therapies [rest, reduced sodium intake, administration of digitalis, diuretic, angiotensin-converting enzyme inhibitor (ACEI) and aldosterone antagonists, etc.]. The patients in metoprolol group were given metoprolol (6.25mg as initiative dose and dose was increased according to illness). NYHA functional classitication, cardiothoracic ratio on chest X-ray film, cardiac output (CO), cardiac index (CI), left ventricular ejection fraction (EF) and LVEDD in echocardiogram were observed, and the plasma BNP level was determined with an immunoradiometric assay (IRMA). Results After 5 months of treatment, the clinical symptoms of patients were improved obviously and p1asma BNP level was significantly lowered in both groups, while p1asma BNP level was significantly lower in metoprolol group compared with control group (200.6?12.1 vs 120.7?14.1, P

Objective To study the effect of multi drug combination therapy of children allergic purpura.Methods 80 cases of children with Henoch Schonlein purpura in our hospital from May 2014 to May 2016 were selected,these children were randomly divided into methylprednisolone,cimetidine and loratadine treatment group(treatment group)and methylprednisolone treatment group(control group),40 cases in each groups,the clinical curative effects,rash regression time,joint pain relief time,abdominal pain relief time,hematochezia disappeared time,urine recovery time,hospitalization time,incidences of adverse reaction and recurrences of the two groups were statistically analyzed.Results The total treatment efficiency of the treatment group was 95％(38/40),which was significantly higher than the control group 70％(28/40),the difference was statistically significant(P<0.05),the rash regression,joint pain relief time,abdominal pain relief time,hospitalization time of the treatment group were significantly shorter than the control group(P<0.05),but the differences the stool disappear time,urine recovery time,incidences of adverse reactions,recurrence rate between the two groups were not significant.Conclusion The effect of multi drug combination therapy of children with allergic purpura is better than single drug alone,can shorten the time of disappearance of symptoms of patients,reduce hospital stay.

Objective To study the level of serum high-sensitive C-reactive protein and HbA1c in diabetes patients with blood stasis syndrome,and to investigate the relationship among them.Methods 58 cases of diabetes patients with blood stasis syndrome and 65 cases without blood stasis syndrome were observed.The level of FPG,hsCRP,HbA1c,24 h UAER,TC,TG,HDL-C and LDL-C were estimated.Results The level of FPG,LDL-C,TG,HbA1c,hsCRP of diabetes with blood stasis syndrome were higher than the control group(P 0.05).In patients with blood stasis syndrome,the hsCRP was positively correlated to HbA1c,24 h UAER,BMI,LDL-C,TC,TG,but the multifactor regression analysis indicated that hsCRP was only correlated to the HbA1c independently.Conclusions The long-term hyperglycemia and inflammatory may be one of the reasons for the formation of blood stasis syndrome of diabetes patients,hsCRP and HbA1c may be new evidences for diagnosis of diabetes patients with blood stasis syndrome.

Objective To investigate the feasibility of laparoscopic repair for ingunal hernia after peritoneal dialysis. Methods Laparoscopic repair of inguinal hernia was conducted in 26 patients with chronic renal insufficiency who had received peritoneal dialysis for a long time. For indirect inguinal hernia, a piece of mesh was placed in the abdominal cavity and the internal ring was sutured and ligated under laparoscope. For direct inguinal hernia, the hernia sac was high suspended and then the mesh onlay was placed under laparoscope. Results The laparoscopy was successfully performed in all the 26 patients, without conversions to open surgery. No postoperative hematoma of scrotum or refractory neuralgia was observed. Follow-up examinations for 6~12 months (mean, 9 months) showed no recurrence. Conclusions Laparoscopic herniorrhaphy for inguinal hernia after peritoneal dialysis is feasible, effective, and safe.
