Objective To investigate of the radiological manifestations in congenital cystic adenomatoid malformation (CCAM) of lung in adult and to improve the diagnostic accuracy of CCAM of lung in adult.Methods Five cases with pathologically proved CCAM of lung in adult were retrospectively analyzed.Chest X-ray was available in 5 cases and chest CT was performed in 2 cases.Results On plain chest radiography,thin wall air cystic lesions with air-fluid level were detected in 3 cases.Honeycomb like small cystic lesion was detected in 1 case.Multiple round cystic lesions were found in 1 case.CT scan of the chest demonstrated a round thin wall air cystic lesion in the lateral segment of right lung's middle lobe,and a thin wall air cystic lesion with the wall merged into the shadow of chest wall in the left apicoposterior segment in one case.Small cystic lesions just like honeycomb were found in bilateral basal segments of the inferior lobes,with a 0.8—1.0 cm sized round mass revealed in the right lung′s inferior lobe basal segment, and the mass was spiculated in another case.Conclusion The imaging signs of CCAM of lung in adult is cyst or cyst-solid and at the risk of developing carcinoma.

Objective To research the method and effect about the bronchoscopic lung volume reduction by ?-cyanoac- rylate in the therapy of chronic obstructive pulmonary disease (COPD).Methods The 14 patients had been examined bosoms by CT before the operation and determined the type of emphysema and the distributing of pneumatocele,had blood gas analyzed and pulmonary function checked.The operation was carried through trachea cannula and intravenous anesthe- sia.When the bronchoscope came to the goal bronchia,we infused the meglumine diatrizoate through the biopsy orifice and approved the location of pneumatocele forward。Then,we infused erythromycin and ?-cyanoacrylate in turn through the biopsy orifice by silica del tube.Results The 3 pneumothorax patients had been removed the drainage tube in 3 days af- ter the operation.8 cases had been counterchecked sternite in one week and the pneumatocele was just like before,among which,1 case developed exudation.1 case had shown pleural thickening in the right-up lung counterchecked sternite 9 months later.1 case been checked the pulmonary function,the FEV_1 enhanced from 24.7% pred before operation to 32. 9% pred after operation one week.3 cases felt polypnea improved greatly and 7 cases felt polypnea improved a little.Con- clusion The bronchoscopic lung volume reduction by ?-cyanoacrylate is a safe,effective and economical method in the therapy of COPD.

Objective To seauch the ideal management for gross hematuria in autosomal dominant polycystic kidney disease (ADPKD).Methods ADPKD patients who were ever hospitalized and followed up in our department since 1993 were enrolled in the study.Demographic and clinical data were colloected,such as gender,age of gross hematuria,level of renal function,causative factors,management strategies,duration of gross hematuria,blood platelet count,activated partial thromboplastin time,prothrombin time,international normalized ratio,size of kidney cyst and so on.ADPKD patients were divided into different groups according to causative factors or management.The clinical data were compared among groups.Results A total of 905 ADPKD patients were screened,among whom 279 patients ever had gross hematuria (male/female:150/129),One hundred and forty-six patients had integrated therapeutic process records,while only 101patients could provide relevant laboratory examination results.In these 101 patients,gross hematuria was found in any stage of chronic kidney disease (CKD); the average eGFR was (56.4±44.1) mml·min-1 ·(1.73 m2)-1; the duration of gross hematuria was (8.8±8.0) d; no significant difference between male and female in duration of gross hematuria existed [(8.2±7.3) d vs (9.5±8.8) d,P=0.426]; coagulation parameters were all normal.The platelet count was also normal in 91 patients.Duration of gross hematuria among groups divided according to different causative factors was significantly different (P＜0.05).The patients in bed rest group had significantly shorter duration of gross hematuria compared with other groups (P＜0.05).The platelet count,prothromhin time and international normalized ratio were all at similar level in different groups.Conclusions The causative factors in ADPKD patients with gross hematuria should be confirmed as the first step of management strategies.Bed rest is the key point in management.Antifibrinolytic agent is a proper choice in the cases receiving bemostatic drugs.It is unnecessary to use antibiotic agent for prevention.

OBJECTIVETo explore the expression of Ghrelin and high mobility group protein B1 (HMGB1) in the serum and the intestinal tissue of sepsis model rats, and to evaluate the effect of electro-acupuncture (EA) at Zusanli (ST36) on the expression of HMGB1 and Ghrelin.

METHODSForty-eight male Wistar rats were randomly divided into four groups, i.e., the sham-operation (sham), the cecal ligation and puncture group (CLP), the CLP + EA at Zusanli (ST36) group (EA), and the CLP + Ghrelin receptor blocking agent + EA group (GHSRA), 12 in each group. A sepsis rat model was prepared by CLP. The incision of the abdominal wall was immediately sutured along the ventral midline for rats in the Sham group. In the EA group EA at Zusanli (ST36) was performed 20 min after CLP surgery with the constant voltage (2 - 100 Hz, 2 mA) for 30 min. In the GHSRA group, Ghrelin receptor blocking agent, [D-Arg1, D-Phe5, D-Trp79, Leu11]-substance P (700 nmol/kg), was administered through intravenous injection immediately after CLP, and 20 min later, EA at Zusanli (ST36) was performed in the same way as for rats in the EA group. Blood samples were withdrawn 12 h after CLP. The serum levels of Ghrelin and HMGB1 were detected using ELISA. Ghrelin expressions and the number of Ghrelin immunopositive cell in the jejunum were determined by immunohistochemistry. HMGB1 contents of the jejunum tissue were detected by Western blotting.

RESULTSCompared with the Sham group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased and levels of Ghrelin and the expression rate of immunopositive cells significantly decreased in the CLP group (P < 0.05). Compared with the CLP group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly decreased, but levels of Ghrelin and the expression rate of immunopositive cells significantly increased in the EA group (P < 0.05). Compared with the EA group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased in the GHSRA group (P < 0.05), but there was no statistical difference in levels of Ghrelin between the two groups (P > 0.05). The serum level of HMGB1 was negatively correlated with Ghrelin in the Sham group, the CLP group, and the EA group (r = -0. 528, P < 0.01).

CONCLUSIONSEA at Zusanli (ST36) could inhibit the expression of HMGB1 in the jejunum of septic rats, and promote the expression of Ghrelin. The expression of HMGB1 was inhibited by Ghrelin receptor blocking agent, which suggested that the anti-inflammation of EA at Zusanli (ST36) might be associated with Ghrelin.

Objective: To assess the level of serum 25(OH)D in patients infected with chronic hepatitis B virus (HBV) at different stages so as to explore their clinical significance. Methods: We quantified the levels of serum 25(OH)D from 246 chronic HBV-infected patients (chronic hepatitis B, n=90; compensated liver cirrhosis, n=70; and decompensated liver cirrhosis, n=86) in the study. Serum 25(OH)D level, liver function, coagulation index, and HBV markers were tested in all the patients. Child-Pugh grade and FIB-4 score of liver fibrosis were calculated in patients with liver cirrhosis. Results: ① The mean serum level of vitamin D in chronic HBV infection patients was significantly lower than that in healthy controls [(14.37±7.18)ng/mL vs. (23.60±6.20)ng/mL, P<0.05]. Serum 25(OH)D level in patients with decompensated cirrhosis was obviously lower than that in patients with chronic hepatitis B [(15.22±6.84)ng/mL, P<0.001] and compensated cirrhosis [(17.16±7.55)ng/mL, P<0.001]. ② Serum 25(OH)D had a positive correlation with ALB level, but a negative correlation with PT level. Serum 25(OH)D level in liver cirrhosis patients was significant negatively correlated with FIB-4 scores. ③ Of the liver cirrhosis patients, 91.9% patients in Child-Pugh C group, 81.6% patients in Child-Pugh B group, and 67.1% patients in Child-Pugh A group had serum 25(OH)D level deficiency. Univariate and multivariate logistic regression analysis showed that CHB patients with FIB-4 score≥1.45 were more likely to develop compensated liver cirrhosis. Compensated liver cirrhosis patients with serum 25(OH) D level <20 ng/mL had the high possibility of decompensation cirrhosis and more severe hepatic injury. Conclusion: Vitamin D deficiency is prevalent in chronic HBV-infected patients, especially in those with decompensated cirrhosis. Vitamin D level can be used as an indicator to assess the severity of chronic HBV infection.

Objective：To study the clinical and pathologic features of patients with lupus nephritis (LN) whose myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive. Methods：The clinical and pathological features were analyzed in 18 patients with LN whose MPO-ANCA were positive. And the data of patients with different clinical outcomes were compared. Results：（1）The hematological abnormalities, hypertension and serositis in these patients were more common than general ones with LN. （2）Proteinuria and hematuria were common, the morbidities of gross hematuria and renal failure in these patients were higher than general ones with LN.（3）Various autoantibodies were positive in these patients.（4）Segmental necrosis crescentic nephritis accompanied by density of immunocomplex in glomeruli and vasculitis in intestitium were common.（5）The morbidity of ESRF and mortality of these patients were similar to general ones with LN. The morbidity of tubular atrophy in those with poor prognosis was significantly higher than those survived. Conclusion：The patients with LN whose MPO-ANCA are positive have some difference from those with negative MPO-ANCA, but positive MPO-ANCA is not directly related to the prognosis.
