The development, application and revision of the clinical practice guideline (CPG) in traditional Chinese medicine (TCM) are a whole thing. However, the development and revision of TCM CPGs have been influenced due to lack of TCM CPGs reporting and feedback channel. Therefore, during the TCM standardization network establish-ment, we studied the application model of TCM CPGs with spontaneous reporting network, in order to provide the ba-sis for further TCM CPGs development and revision.

Objective To summarize the clinical characteristics, diagnosis and surgical management experiences of 51 cases of pulmonary fungal infections. Methods The clinical data of 51pulmonary fungal infection patients hospitalized in department of thoracic surgery of PLA General Hospital from 1981 to 2008 were retrospectively analyzed. Results The recruited cases included three cases of Candida albicans, 22 of Aspergillus, and 26 of Cryptococcus. The clinical symptoms included cough, hemoptysis, fever, chest tightness, chest pain and asthma. Twenty cases were identified through routine healthy examination. Of chest X-ray and computed tomograply scan, 29 cases presented with solid nodules in the lung, some of which had burrs and spikes; 13 presented with pulmonary cavity with even wall thickness and smooth inner wall including 7 with aspergillar glomera.Forty-eight cases underwent standard thoracotomy operations and 3 cases underwent thoracoscope or thoracoscopy-assisted minithoracotomy. Seventeen underwent pulmonary lobectomies, and 34 wedge resections. There was no operative mortality in the 51 patients. All diagnoses were confirmed by postoperative pathology. There was no relapse during 3- 10 years of follow-up. Conclusions Primary pulmonary fungal infections lack characteristic presentations in clinical manifestations and imaging examinations. Pathology is the evidence for definite diagnosis. Surgical intervention is an effective tool for diagnose and treatment of this disease.

Objective To investigate the early risk factors of the formation of pancreatic pseudocysts after severe acute pancreatitis. Methods One hundred patients with severe acute pancreatitis admitted from Jul. 2005 to Mar. 2007 were included. Clinical and laboratory data within 24 hours of admission and radiological tests of chest, abdominal dynamic contrast-enhanced computed tomography and abdominal ultrasound within 3 days after admission were analyzed and multiple stepwise logistic regression analysis was performed. Results 30 patients developed pancreatic pseudocysts and the incidence of pancreatic pseudocysts in the clinical course of severe acute pancreatitis was 30%. There were significant difference between group A (pancreatic pseudocyst group) and group B (non-pancreatic pseudocyst group) in serum albumin[(33.23±4.810g/L vs (36.07±4.92)g/L], CT severity index (CTSI) (3~6 vs 2~4 points) ,length of hospital stay[(26.83±19.760) day vs (14.51±7.71) days, (P<0.05)]. Meanwhile, there were no significant differences between the two groups in age, gender proportion, body temperature, heart rate, breath rate and mean arterial pressure in admission,urine volume within 24 hours, early defaecation within 24 hours after admission, blood routine, liver function, kidney function, electrolytes, blood cholesterol and triglycerol, PT, APTr, arterial blood gas analysis, blood amylase, C-reaction protein, APACHE Ⅱ, RANSON scoring, early ascites and pleural effusion. But multiple stepwise logistic regression analysis showed that the serum albumin and CTSI were associated with the formation of pancreatic pseudocysts after severe acute pancreatids. Conclusions The serum albumin and CTSI were the independent risk factors of the formation of pancreatic pseudocysts after severe acute pancreatitis.
