Objective To explore the origin of chronic subdural heamatoma.Methods Follow-up 92 patients of acute subdural haematoma(ASDH)and 207 patients of traumatic subdural effusion(TSE)S by CT or MRI.Results None of ASDHs developed into CSDHs directly,but ASDHs could become to CSDHs via TSEs;67 cases of TSE was proved becoming to CSDHs by CT scanning or operation.Conclusions Origin of CSDH is TSE.

Objective To summarize our experience in the management of calculous atrophic cholecystitis by laparoscopic choleycystectomy(LC). Methods 56 cases of calculous atrophic cholecystitis treated by LC from 1997 to 2000 were analyzed retrospectively. Results 52 cases treated by LC including antergrade resection in 39 ones, retrograde resection in 13 ones were successfully completed. 4 patients were converted to open cholecystectomy, 3 of whom underwent choledochotomy and T-tube drainage. There was abdominal cavity drainage in 8 cases. 56 patients were an cured. Bile leakage occurred in 2 cases, and the patients were cured by conservative treatment. Conclusions It's key point to perform LC successfully for patients with calculous atrophic cholecystitis by getting well known of the junction site of ampulla and cystic duct, selecting indications of LC strictly, converting to open operation as necessary and putting preventive drainage- tube.

Objective To investigate the effects of valsartan on the expression of acyl-coenzyme A: cholesterol acyltransferase-1(ACAT-1) and peroxisome proliferator activated receptor-gamma(PPAR-?) in atherosclerotic plaques on rabbit aortic wall.Methods Twenty-four male Japanese white rabbits were randomly assigned into three groups(8 each): control group,valsartan group and high cholesterol feeding group.All rabbits were fed according to the experimental protocol for 12 weeks.Blood samples were taken from vein for measurement of serum lipids.The ratio of intima/media thickness of the aorta was measured.ACAT-1 mRNA/protein and PPAR-? mRNA/protein were determined by reverse transcription polymerase chain reaction(RT-PCR) and Western blotting,respectively.Results After 12 weeks,the levels of serum total cholesterol(TC),triglyeride(TG) and low density lipoprotein-cholesterol(LDL-C) in valsartan group and cholesterol group were significantly higher than those in control group(P0.05).The intima thickness and the ratio of intima/media in carotid arteries in cholesterol group were significantly higher than those in control group and valsartan group(P

Objective To investigate differentially expressed genes in the liver of rats with idio-pathic hyperoxaluria by cDNA microarray. Methods Three male rats with idiopathic hyperoxaluria were set as study group, 3 normal ones as control. Total RNA was isolated by one-step protocol from the liver of rats in the 2 groups and mRNA was purified, reversely transcribed, labeled with Cy3 or Cy5 and hybridized to gene chip containing 26 962 target genes of rat. The differences in gene expres-sion profile between the 2 groups were analyzed by bioinformatics methods. Results Comparative a-nalysis revealed that the expression of 123 genes was up-regulated and 24 genes was down-regulated by two-fold in the liver. These genes were associated with cell receptor, immune, cell signal transduc-tion, amino acid metabolism, protein translation, cell proliferation and others. Conclusion cDNA microarray could be used effectively to screen differentially expressed genes in the liver of rats with idi-opathic hyperoxaluria in which many different kinds of genes were involved.

Objective To summarize the clinical features, diagnosis and treatment of Ménétrier disease in China. Methods A systematic review of Ménétrier disease in China was performed. Four electronic databases were searched from 1993 to 2008 including CNKI and Wanfang seeking studies about pathologically performed Ménétrier disease. Results Data of 95 patients with Ménétrier disease from 62 studies was included. There were 74 males and 21 females. The mean age of onset in adults was (47.4± 5.3) years . The process of the disease was longer in male individuals that in female individals (47.5 months vs. 13.7 months, P<0.05). The main symptoms included abdominal pain (76.8%), weight loss (42.1%), anorexia (40.0%) and edema of lower extremities (36.8%), etc.Hypoproteinemia was accounted for 71.6 % and most of the patients had hypochlorhydria. The typical giant hyperplastic gastric fold was found in 88.4 % of the patients under endoscopy. The diffuse type was in predominance and mainly involved the greater curve of the stomach (55.3 %). Whereas 5.3 patients were accompanied with gastric cancer. The misdiagnostic rate of the disease was 31. 6%,which accounted for 50% in surgically treated patients. Conclusions In China, the Ménétrier disease is predominant in middle-aged males, and the process is longer in males than in females. Misdiagnosis is related to existence of weight loss and hypoproteinemia. Most of the patients with Ménétrier disease have a good prognosis even the disease process is long.

Objective To guide bracing treatment for adolescent idiopathic scoliosis (AIS). Methods A total of 68 AIS patients with apex vertebrae (AV) under T6 had received the improved Cheneau bracing treatment between March 2008 and June 2010. All patients were divided into two groups. There were 16males and 35 females, with a mean age of 13.6 years (range, 10.6-17.2) in the intervention group. The mean Cobb angle was 29.5° (range, 20°-38°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the group;while there were 6 males and 11 females, with a mean of 13.2 years (range, 10.8-16.8) in the control group.The mean Cobb angle was 28.7° (range, 20°-37°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the control group. All patients in control group were informed standardized bracing treatment method. But we gave patients in intervention group two copies of "The Form of Guiding Bracing Treatment" treatment of patients with AIS, and informed that they carried out the bracing treatment according requirement of the form.Cobb angle was measured before the treatment and at 6th, 12th, 18th month after treatment. Results Sixtyfive cases were followed up for 18-27 months. However, one female in control group and two females in intervention group were lost during follow-up. Coefficient and intraclass correlation coefficient of form were both over 0.60. The acceptance rate of the table was 97.54%(199/204), qualified rate was 100.00%( 199/199), and with good content validity. The mean Cobb angle decreased gradually from 28.71° to 25.76° in control group and from 29.47° to 21.59° in intervention group. Four cases in control group and 34 cases in intervention group had reduced more than 5° at 18 months after treatment. There was significant difference regarding Cobb angle between two group. Conclusion The form of guiding bracing treatment has good reliability and validity and can guide bracing treatment of AIS correctly and effectively.

Objective To discuss the types of ICC and characteristics of spontaneous Ca2+ waves of different types of ICC in the bladder of guinea pig. Methods Frozen-sections were made from the bladder of guinea pig and ICC were cultured in vitro. Cells were stained by indirect immunofluorescent method and detected by Laser scanning confocal microscope. The ICC cultured in vitro were divided randomly into 4 group: dimmer ICC,monomer ICC,dimmer ICC treated with 2-APB group and monomer ICC treated with 2-APB group according to the cell morphology and disrupted with 2-APB.The calcium concentration of ICC cultured in vitro were marked with Fluo-4 AM and disrupted by 2-aminoethoxydipheylbrate (2-APB, 100 μmol/L) in dimmer ICC treated with 2-APB group and monomer ICC treated with 2-APB group. The calcium oscillation function of ICC was observed under Laser scanning confocal microscope. Results For the monomer ICC and dimmer ICC in frozen sections and cultured in vitro,there were increased frequency (P＜0.01) and amplitude (P＜0.05) of spontaneous Ca2+ waves in dimmer ICC compared with the monomer monomer ICC. But after the cells disrupted by 2-APB after 15 min,There were decreased frequency (P＜0.01) and amplitude (P＜0.01) of spontaneous Ca2+ waves in the dimmer ICC treated with 2-ABP group compared with the dimmer ICC. The changes(P＞0.05) of spontaneous Ca2+ waves was not statistical significance in monomer ICC treated with 2-ABP group compared with monomer ICC group. Conclusions The bladder of guinea pig may exist 2 different types of ICC, dimmer ICC and monomer ICC. The excitability of spontaneous Ca2+ waves of dimmer ICC could be higher than in monomer ICC. The special structure of dimmer ICC may contribute to the formation of high spontaneous Ca2+ waves.

AIM: To determine the expression of c-kit mRNA and protein in the bladders in guinea pigs with diabetic cystopathy (DCP) and to explore the correlation and mechanisms between c-kit expression and DCP. METHODS: Sixty guinea pigs were divided randomly into control group (n=20) and experimental group (n=40). The guinea pigs in experimental group were injected with streptozotocin (STZ) to induce diabetes mellitus. After fed for 10 weeks, the animals in both groups were tested with urodynamics, and the guinea pigs in experimental group were divided into the subgroups of DCP and the diabetic no-cystopathy (NDCP) group according to the results of urodynamics. mRNA expression of c-kit was detected by reverse transcription polymerase chain reaction (RT-PCR) and protein expression of c-kit was tested and analyzed by laser scanning confocal microscope. RESULTS: Decreased expression of c-kit mRNA was observed in DCP group compared to control and the NDCP group. The ratio of c-kit mRNA and GAPDH was 5.66±0.54 in controls (P<0.05), 5.54±1.28 in NDCP group (P<0.05) and 4.65 ±0.47 in DCP group. c-kit protein expression significantly declined in DCP group. The mean value of fluorescence intensity was 856.52± 53.03 in control group, 844.67± 59.24 in NDCP group and 548.69± 48.51 in DCP (P<0.01).CONCLUSION: The declined expression of c-kit) gene at transcription and translation levels destroys the SCF/c-kit signal pathway, leading to the dysfunction of Cajal-like) cells in DCP guinea pig, so the abnormal expression of c-kit gene is involved in the pathogenesis of DCP.

Objective:To observe the therapeutic effects of lung protective ventilation on acute lung injury caused by chest trauma and seawater.Methods: Acute lung injury was induced in 18 healthy dogs by open pneumothorax and seawater and the dogs were then randomly divided into 3 groups: non-treatment group(received no treatment),common treatment group(nasal ventilation,thoracic drianage and intravenous 5% glucose solution) and lung protective ventilation group(mechanical ventilation,thoracic drianage and intravenous 5% glucose solution).Blood samples were taken at different time points to observe the changes of blood gas(PaO_(2),PaCO_(2)and PaO_(2)/FiO_(2)),hemodynamic parameters(heart rate,mean blood pressure,cardiac output) and cytokines(TNF-?,IL-4 and IL-8).Results: After injury,PaO_(2) declined significantly in the dogs,PaO_(2)/FiO_(2) was lower than 300 and the levels of TNF-?,IL-6 and IL-8 were increased obviously.PaO_(2),PaO_(2)/FiO_(2) and TNF-? level were significantly higher in lung protective ventilation group than those in common treatment group(P
