This article introduced the application ofHuanglian WendanDecoction on bile heat syndrome treatment, worthy of clinical reference.

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 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

Wingless type protein (Wnt protein) is a group of protein which plays an important role in the process of animal growth and hemopoiesis,the signaling pathway they conducted was called Wnt signaling pathway,and its abnormal activation can lead to many tumors,include lung caner.As a tumor suppressor gene,WIF-1 can restrain the activation of Wnt signaling pathway,which can avoid lung cancer.WIF-l's methylation can downregulate the expression of WIF-1,which can activate Wnt signaling pathway and cause lung cancer.So the detection of WIF-1's methylation may contribute to clinical diagnose of lung cancer,and therapy of WIF-1 's methylation may be one of the treatment metheds of lung cancer.

ObjectiveTo summarize the experiences for nursing esophageal cancer patients undergoing chest laparoscopic intrathoracic esophagus anastomosis.Method The clinical data of 67 esophageal cancer patients before and after chest laparoscopic intrathoracic esophagus anastomosis were retrospectively reviewed for summarizing nursing experience.Result All 67 patients were discharged successfully,including 2 contracting anastomotic leak symptoms but cured by conservative therapy,4 contracting lung infections but cured after antimicrobial therapy,and another 2 contracting acute renal failure and cured by way conservative therapy as well.Conclusion Comprehensive preoperative preparation,accurate surgical operation and effective pre- and post-operative nursing measures can accelerate the healing,improve the cure rate and reduce the occurrence of complications.

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.

Objective To summarize the clinical experience of laparoscopic cholecystectomy (LC) in the treatment of acute cholecystitis. Methods A total of 93 cases of acute cholecystitis treated by LC from May 2003 to May 2005 was retrospectively reviewed, including 15 cases of preoperative endoscopic retrograde cholangiopancreatography (ERCP) combined with endoscopic sphincterotomy (EST) for common bile duct stones and 6 cases of intraoperative cholangiography. The LC was performed within 48 hours after admission. Results The LC was successfully completed in 91 cases (97.8%), whereas a conversion to open surgery was required in 2 cases (2.2%). The operation time was 35~160 min (mean, 65 min). Postoperatively, biliary leakage occurred in 3 cases (3.2%) and residual stones in the common bile duct were found in 3 cases (3.2%), which were all cured by open surgery combined with ERCP, EST, and endoscopic nasobiliary drainage (ENBD). No iatrogenic injuries happened. Conclusions With proper selection of ERCP and EST, LC for the treatment of acute cholecystitis is feasible and safe. But the incidence of conversions and complications may be high.

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 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.
