Periodontal health and quality of life in patients with chronic obstructive pulmonary disease.

Objective: To evaluate the association of periodontal health and parameters of quality of life assessed in 306 Chinese patients with chronic obstructive pulmonary disease (COPD).

Methods: Periodontal status and respiratory function in 306 COPD patients were clinically evaluated and their quality of life was assessed using the standardized St George's Respiratory Questionnaire (SGRQ).

Results: The SGRQ scores were all significantly correlated with major lung function parameters (r(2) = -0.

[The relationship between gastroesophageal reflux disease and idiopathic pulmonary interstitial fibrosis].

Objective: To determine the prevalence of gastroesophageal reflux disease (GERD) in patients with idiopathic pulmonary interstitial fibrosis (IPIF).

Methods: From December 2006 to January 2008, 24 consecutive patients with IPIF admitted to Beijing Chaoyang Hospital underwent 24-hour esophageal pH monitoring and esophageal manometry. Meanwhile, 23 patients with diffuse parenchymal lung disease (DPLD) (excluding IPIF) admitted to the hospital in the same period served as a control group.

[Causes of respiratory failure complicating interstitial lung disease and application value of mechanical ventilation].

Objective: To investigate the potential causes of respiratory failure in patients with interstitial lung disease (ILD) and evaluate the application value of mechanical ventilation (MV) in its treatment.

Methods: This study included the clinical data of 47 ILD patients (29 males and 18 females) complicating respiratory failure and admitted to respiratory care unit (RICU) for receiving MV at Beijing Chaoyang Hospital from January 1, 1998 to June 30, 2008. The median age was 67 years old.

[Association between the erythrocyte sedimentation rate, serum C-reactive protein and risk of lung cancer].

Objective: To explore the association between the erythrocyte sedimentation rate, serum C-reactive protein (CRP) and the risk of lung cancer.

Methods: One hundred and three patients with newly diagnosed lung cancer and 85 homochronous hospitalized patients with chronic respiratory diseases (including chronic obstructive pulmonary disease, asthma, bronchiectasis and pulmonary fibrosis) were included in this study. ESR, serum levels of CRP, CEA, CA19-9 and CA125 were analyzed in the two groups before the initiation of any therapy after hospitalization.

[Airway inflammation and peripheral airway function in asthmatic patients with different control levels].

Objective: To observe the airway inflammation and peripheral airway function in asthmatic patients with different control levels, and to investigate whether the airway inflammation profile detected by induced sputum reflects the peripheral airway dysfunction.

Methods: The recruited asthmatic subjects (n = 66) were divided into 3 groups: asthma controlled (8 male and 13 female), asthma partly controlled (12 male and 16 female), asthma uncontrolled (6 male and 11 female). Twenty healthy subjects served as the control group (9 male and 11 female).

[Testis necrosis following repeated misdiagnosis of testicular torsion: a case report and literature review].

Objective: To improve clinicians' ability of diagnosing testicular torsion.

Methods: We reviewed the data of a case of testicular torsion that resulted in necrosis because of delayed presentation and repeated misdiagnosis, and analyzed its anatomic features, clinical manifestations, ultrasound results, the causes of misdiagnosis and relevant literature.

Results: The patient presented 5 hours after the onset of symptoms, complaining of severe paroxysmal pain in the lower left abdomen, accompanied with nausea and vomiting, and was twice misdiagnosed as having enterospasm or ureteral calculus at two different hospitals.

The effects and mechanisms of mycophenolate mofetil on pulmonary arterial hypertension in rats.

Pulmonary arterial hypertension (PAH) is a severe clinical and pathophysiologic syndrome with no effective treatment at present. Mycophenolate mofetil (MMF), a prodrug of mycophenolic acid (MPA), has been applied widely to the treatment of connective tissue diseases with the effect of immunosuppressant. Its anti-proliferation has been found recently.

Giant hepatobiliary cystadenoma in a male with obvious convex papillate.

Hepatobiliary cystadenoma is an uncommon lesion that is most often found in middle-aged women and difficult to diagnose preoperatively. Here, we report a case of giant hepatobiliary cystadenoma in a male patient with obvious convex papillate. On the basis of imaging examinations, the patient was diagnosed as hepatobiliary cystadenoma prior to operation.

Prophylactic effect of glyceryl trinitrate on post-endoscopic retrograde cholangiopancreatography pancreatitis: a randomized placebo-controlled trial.

Aim: To examine the prophylactic effect of glyceryl trinitrate on post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and hyperamylasemia.

Methods: Patients scheduled for ERCP were randomly divided into study group and placebo group. Patients in study group and placebo group were treated with 5 mg glyceryl trinitrate and 100 mg vitamin C, respectively, 5 min before endoscopic maneuvers.

[Diagnosis and management of transplant renal artery stenosis caused by early stage acute allograft rejection].

Objective: To investigate the diagnosis and management of transplant renal artery stenosis (TRAS) caused by early stage acute allograft rejection.

Method: A retrospective study was conducted in 3 cases with diagnoses of TRAS and early stage acute allograft rejection confirmed by color Doppler ultrasonography, renal artery angiography, and renal graft biopsy.

Results: Antirejection therapy was carried on subsequently rather than percutaneous transluminal angioplasty or percutaneous transluminal angioplasty and stenting.

Laparoscopic cystogastrostomy for the treatment of pancreatic pseudocysts: a case report.

Pancreatic pseudocysts (PPs) are collections of pancreatic secretions that are lined by fibrous tissues and may contain necrotic debris or blood. The interventions including percutaneous, endoscopic or surgical approaches are based on the size, location, symptoms and complications of a pseudocyst. With the availability of advanced imaging systems and cameras, better hemostatic equipments and excellent laparoscopic techniques, most pseudocysts can be found and managed by laparoscopy.

[Influence of overexpressed coagulant and fibrolytic components in tumor tissues on the prognosis of non-small cell lung cancer].

Objective: To evaluate the expression of tissue factor (TF), urokinase-type plasminogen activator (uPA), and urokinase-type plasminogen activator receptor (uPAR) in non-small cell lung cancer (NSCLC) tissues and to find their roles in lymph node metastasis, vascular involvement and prognosis.

Methods: Immunohistochemistry was used to examine the expression of TF, uPA, and uPAR in the tumor tissues of 97 NSCLC patients obtained during operation and 40 samples of normal lung tissues at least 5 cm away from the tumor tissues. The correlations of expression of TF, uPA, and uPAR with the clinicopathologic parameters were analyzed by chi2 test.
