ObjectiveTo observe the efficacy and safety of inhaled tiotropium capsule on adult bronchial asthma.MethodsThirty-four adult asthma patients were randomized into two groups.We evaluated the addition of tiotropium bromide to an inhaled glucocorticoid in the treatment group( n =17 ),as compared with the addition of the LABA Formoterol in the control group ( n =17 ).Serial measurements of lung function,symptom control and quality of life were performed.ResultsAfter 8 weeks of treatment,peak expiratory flow (PEF) in the addition of tiotropium bromide group[ ( 359 ± 12 ) L/min vs.( 275 ± 5 ) L/min,P ＜ 0.05 ] and the addition of the LABA Formoterol group [ ( 346 ± 11 ) L/min vs.( 275 ± 9 ) L/min,P ＜ 0.05 ] were significantly higher than those before treatment.The forced expiratory volumes in one second ( FEV1 )were also significantly elevated in both groups [ Tiotropium bromide group:( 2.80 ± 0.28 ) L vs.( 2.30 ± 0.28 ) L,P ＜ 0.05 ; LABA Formoterol group:( 2.69 ± 0.34 ) L vs.( 2.25 ± 0.34 ),P ＜ 0.05 ] compared with pre-treatment.Average dose of emergent drug ( ventolin ) usage were decreased in both groups after treatment [ Tiotropium bromide group:(0.96 ± 0.34 ) puff/d vs.(4.11 ± 1.03 ) puff/d,t =3.05,P ＜ 0.05 ; LABA Formoterol group:( 0.88 ± 0.44 )puff/day vs.( 4.43 ± 0.87 ) puff/day,t =3.23,P ＜ 0.05 ].Meanwhile,significantly improved quality of life scores and alleviation of asthma symptom were found in both groups as compared with baseline ( P ＜ 0.05).However,no significant differences in the above variables after treatment were found between two groups( P ＞0.05 ).ConclusionWhen added to an inhaled glucocorticoid,tiotropium improved symptoms and lung function in patients with inadequately controlled asthma.Its effects appeared to be equivalent to the addition of Formoterol.

Objective To analyze incidence of thyroid carcinoma and to explore and conclude the principle of its diagnosis and treatment.Methods One hundred and forty six patients of thyroid carcinoma in our hospital were analyzed and discussed with literature.Results 101 cases were diagnosed as thyroid carcinoma by pathological diagnosis of fast frozen sections,the positive ratio is approximately 93.5%.totle resection of affected lobe and isthmus was performed on 35 cases,total resection of affected lobe and isthmus and majority of opposite lobe was done on 37 cases.The lymph node metastasis was found by postoperative pathological diagnosis with a rate of 32.5%.Conclusions Preoperative diagnose of thyroid carcinoma is rarely available,diagnosis of thyroid carcinoma by fast frozen sections is optimal.total resection of affected lobe and isthmus or total resection of affected lobe and isthmus and majority of opposite lobe are the main operation patterns.

Objective To investigate effects of bone marrow mesenchymal stem cells (MSC) on severe acute pancreatitis (SAP) in rats.Methods A total of 60 rats were randomly divided into normal group (n =10),the model of SAP group (n =10),the transplantation of the MSC group (n =20),the combination of the MSC and the granulocyte colony-stimulating factor (G-CSF) group (n =20).The conversion rate of MSC was detected by using immunofluorescence methods,and the level of amylase in serum was assayed by using biochemical methods.Simultaneously,the level of interleukin-6 (IL-6) in serum was determined by using enzyme linked immunosorbent assay (ELISA).Results The conversion rates of the MSC increased,and consequently,the levels of amylases and interleukin-6 in serum were reduced (P ＜ 0.05).When a small amount of the G-CSF was added to MSC,the therapeutic effects of the two different kinds of cells were synergistically strengthened.In the contrary,when a large number of the G-CSF was added to MSC,the antagonism resulted between these two different kinds of cells gives rise to harmful effects on SAP.Conclusions The bone marrow mesenchymal stem cells have therapeutic effects on SAP.When the number of the bone marrow mesenchymal stem cells increases,the protective effects are enhanced.

Objective To evaluate the therapeutic effect of endoscopy for patients with anastomotic or nonanastomotic biliary strictures after liver transplantation.Methods Clinical and follow-up data of 56 patients,38 (67.9％) with anastomotic strictures (AS),and 18 (32.1％) with nonanastomotic strictures (NAS) after liver transplantation,who underwent endoscopic therapy were collected and analyzed.Results Compared to AS patients,NAS patients showed shorter time from liver transplantation to initial presentation (4.45 ± 1.47 vs.8.00 ±2.31 months,P =0.000),underwent more ERCP procedures (6.20 ±1.28 vs.4.11 ± 1.51,P =0.000) and received more stents (10.20 ±3.59 vs.7.53 ±2.12,P =0.001).Although the success rate was not statistically different,patients with NAS needed longer treatment duration and had higher recurrence rate (50.0％ vs.18.2％,P =0.033) as well as shorter duration from treatment to recurrence.Among patients with AS,the treatment failure group had longer stricture length (13.00 ±3.61 vs.6.63 ±2.09,P =0.000) than the success group and the patients who experienced recurrence had longer stricture length (10.48 ± 1.07 vs.5.86 ± 1.55,P =0.000) and narrower stricture diameter (1.52 ± 0.38 vs.1.94 ± 0.32,P =0.001).Among NAS patients,the multiple biliary strictures group had lower success rate and higher recurrence rate,but with no statistical significance (62.5％ vs.90.0％,P =0.275 and 66.7％ vs.37.5％,P =0.592,recpectively).Conclusion NAS patients have lower response to endoscopic treatment than AS patients.The length and diameter of biliary stricture in AS as well as the number of stricture in NAS may influent the effect of endoscopic treatment.

ObjectiveTo investigate the relationship between intramural gallstones and intraluminal gallstones. MethodsIn this present study, the control study was applied to analysis on the gallstones from 116 cholecystolithiasis patients with intramural gallstones as well as intraluminal gallstones. All the patients were from the general surgery department and accepted gallbladder-preserving cholecystolithotomy during 2009.02-2009.08. Meanwhile, 171 patients with intraluminal gallstones were investigated the clinical traits; and gallstones from them were analyzed with FT-IR and microsopic examination. ResultsThe results showed the coincidence rate of stone type was 97.4％, and it was mainly pigment gallstones and mixed gallstones in 116 cases; the coincident detection rate of clonorchis sinensis eggs was 98.3 ％, and it was much higher in the pigment gallstones and mixed gallstones than that in the cholesterol gallstones. The ratio of pigment gallstones from the 116 patients group was higher than the 171 patients group, and the detection rate of C. sinensis eggs of the two groups had no statistical difference (P＞0.05). ConclusionsThe stone type of intramural gallstones was mainly pigment gallstones and mixed gallstones. Intramural gallstones and intraluminal gallstones were homologous.

Objective To investigate the changes of serum gastrin level in patients with colon cancer and the relationship between serum gastrin level and colon cancer occurrence and development.Methods Data of 35 patients underwent colon cancer surgery from January 2010 to January 2012 in our hospital were collected,at the same time data of 28 patients with colonic polyps and 30 cases of normal were collected as normal control.Serum gastrin levels were tested by radioimmunoassay in patients with colon cancer before surgery,1,3,7 d after surgery and they were analyzed.Results The serum gastrin level of patients with colon cancer was significantly increased compared with colon polyps and healthy controls((92.45 ± 12.98) ng/L vs (49.66 ±10.34) ng/L vs (30.12 ±6.39) ng/L;F =9.455,P ＜0.001)).Serum gastrin level in patients with obstructive colon cancer was significantly higher than that in non-obstructive cancer((129.84 ± 15.32) ng/L vs (75.34 ±11.45) ng/L,t =12.181,P ＜0.001) ;Serum gastrin levels in patients who cut off colon tumor was signifcanfly lower than before surgery((43.02 ±8.34) ng/L,(40.74 ±6.78) rig/L,(38.12 ±7.09) ng/L vs (89.45 ±12.98) ng/L;P ＜0.05).But no significant change of serum gastrin levels in patients with the colon tumor compared with the preoperative((97.34 +8.30) ng/L vs (95.82 ±7.20) ng/L vs (94.44 ±7.74) ng/L vs (100.23 ± 10.82) ng/L; P ＞ 0.05).But there was significant difference on serum gastrin levels between patients who cut off colon tumor and patients with the colon tumor(within groups:F =8.341,P =0.012 ;between groups:F =7.871,P =0.024).Conchusion Serum gastrin levels in patients with colon cancer were significantly higher than that of patients with colon polyps and normal controls.There was also a significant reduction of serum gastrin in tumor resection,and therefore gastrin may be involved in the development of colon cancer.
