Objective To explore the pathological characteristics, diagnosis and operative treatment of Mirizzi Syndrome(MS). Methods The clinical data of 95 cases of Mirizzi Syndrome admitted to our hospital in recent 12 years were reviewed retrospectively. Results All of the 95 cases underwent operative therapy. In the 95 patients, simple cholecystectomy was performed in 2 patients, cholecystectomy and choledochotomy with T tube drainage in 58 patients, cholecystectomy and choledoscopic bile duct examination via cystic duct in 15 patients, partial cholecystectomy plus repair of choledochal fistula in 18 patients, and cholecystectomy plus repair of the injured choledochus in 2 patients. 65 cases were folloned up for 1-5 years, and all of them have been in good health. Conclusions Mirizzi Syndrome consists of varied pathology. The selection of rational operation for different types of Mirizzi Syndrome can give satisfactory results.

PURPOSE: Chronic granulomatous disease(CGD) is a group of genetic disorders characterized by recurrent pyogenic infections of the respiratory tract, skin,and soft tissue. The aim of this study is to describe the radiological findings of CGD. MATERIALS AND METHODS: We retrospectively analyzed radiological findings of 11 patients of CGD, which were diagnosed by nitroblue tetrazolium test. We analyzed the pattern of pneumonia on chest radiograph in all infants. Three cases of chest CT and one case of digital subtraction angiography were performed. According to infant's symptom, abdominal ultrasonography(n=8), abdominal CT(n=5), simple bone radiography(n=2), and brain CT(n=I) were performed. RESULTS: Repeated infiltration(100%), mass-like consolidation(73%), hilar or mediastinal lymph node enlargement(64%), scattered nodules(55%), cavity formation(27%), and pleural effusion(27%) were found on the chest radiographs(n=11) and CT(n=3). On the abdominal imagings(n=8), there were hepatosplenomegaly(n=6), calcifications in the liver(n=2) and kidney(n=1), hepatic granuloma(n=1) and renal abscess(n=1). Two patients had osteomyelitis. There were findings of meningitis on brain CT(n=1). CONCLUSION: We believe that the combinations of these radiological findings may suggest the diagnosis of CGD in patients with history of reccurent infection.

With the deterioration of environment, and the excessive collection of wild resources, the wild populations of Myla- bris phalerata Pallas are less and less, almost extincted in many traditional distribution areas. It is necessary to breed M. phalerata artificially for sustainable utilization. Food preference of adult M. phalerata is the key to its provenance screening and domestication in the artificial breeding. In this paper, the food preference of 3 geographical populations of M. phalerata was studied. The results showed that the food preferences of adult M. phalerata in different geographical populations were different. The adult M. phalerata in Wuming preferred cucumber flowers, gourd flowers and melon flowers. The adult M. phalerata in Tianlin preferred cowpea flowers. And the adult M. phalerata in Guangzhou preferred cowpea flowers and gourd flowers. Gourd flowers were the most attractive food for the adult M. phalerata of 3 geographical populations of M. phalerata.

Objective To synthetically evaluate medical treatment outcomes of two operative methods on benign prostatic hyperplasia (BPH),and to provide evidence for therapeutic regimen selection.Methods Prospective cohort study was applied.BPH patients were treated by two operative methods randomly,follow-up observations were carried out at 3 months,6 months,and 48 months after the treatment.IPSS and BPHQLS were adopted to evaluate prostate and quality of life of patients at different time.The weight coefficients of IPSS score,quality of life score and general hospitalization expense in the comprehensive evaluation were defined by the Delphi Method.Results The synthetic score of both groups showed ascending trend,comprehend evaluation of scores got after treatment for 3 months (OP group was 7.6±0.7,TURP group was 7.4±0.8),6 months(OP group was 6.9 ± 0.9,TURP group was 6.9 ± 1.1) showed no significant differences between two groups(P＞0.05),curative effect of OP group was better than TURP group at 48 moths(OP group was 8.3±0.9 score,TURP group was 7.6± 0.8 score) (P＜0.05).Conclusions The curative effect of OP group was better than TURP group at 48 months.

Objective To study donor liver repair in modified piggyback liver transplantation and its ~relationship to postoperative complications. Methods The relationship between donor liver repair and ~development of complications of 14 cases of modified piggyback liver transplantation,which among 17 cases of orthotopic piggyback liver allotransplantation performed in our hospital,were analyzed retrospectively.In the 14 cases,abnormal hepatic artery was repaired in 2 cases,portal vein interposition shunt was done in 1 case;~repaired ligaments were sutured in 10 of 14 cases,and not sutured in 4 cases.Results None of the 14 ~patients died in the perioperative period. The success rate of the operation was 100%. 3 patients had ~intra-abdominal bleeding,postoperatively,and in 2 cases the bleeding was related to donor liver repair. ~Postoperatively ,there was no thrombosis of hepatic artery or portal vein, and no bile duct necrosis, no hepatic outflow tract occlusion. Conclusions Donor liver repair is an important procedure in liver tramsplantation.The quality of donor liver repair is directly related to the difficulty of operative technique during liver ~transplantation ,and to the development of postoperative complications.In donor liver repair during piggyback liver transplantation,reconstruction of the retrohepatic vera cava is very important.The constructed stoma must be compatible with the donor hepatic vein outflow stoma and be able to effectively prevent the formation of eddy blood flow,ensure patency of the outflow tract and effectively prevent thrombus formation.

OBJECTIVE: To provide reference for patients with type I incisions about rational use of antibiotics.METHODS: Between Oct.2007 and Mar.2008,a total of 1 024 medical records of patients with type I incisions from orthopaedics,common surgery,department of gynecology in 12 hospitals of Xining area were sampled for analysis of prophylactic use of antibiotics.RESULTS: 100.0% of the type I incision patients received prophylactic antibiotics;28.4% used antibiotics without indication;16.9% used antibiotics at 0.5～2 h before operation;33.4% used antibiotics at more than 2 h before operation;and 49.7% received antibiotics postoperatively rather than preoperatively.The irrational and nonstandard use of antibiotics manifested as improper in the choice of drug variety,nonstandard in drug combination,irrational in dosage and administration,prolonged use of antibiotics,lacking basis for the change of drug variety etc.CONCLUSION: The prophylactic use of antibiotics in patients with type I incisions from 12 hospitals of Xining area is far from perfect,therefore,it is urgent to strengthen the standard management on the use of antibiotics.

BACKGROUND:The occurrence and severity of denture stomatitis are closely related to denture cleaning methods and wearing time. Therefore, it is of great significance to explore the effects of denture cleansers on denture surface roughness and color stability.OBJECTIVE:To investigate the effects of four different denture cleansers on the surface roughness and color stability of heat-curing denture base resins and elastic denture base materials by means of soaking test.METHODS: Samples of heat-curing denture base resins (n=25) and elastic denture base materials (n=25) were polished and soaked in NaClO, Efferdent, Polident partial, Polident overnight and water, respectively. The soak process was repeated 90 times. Then the color aberration and surface roughness were tested using color meter and roughmeter before soaking and after 30, 60, 90 times of soaking.RESULTS AND CONCLUSION:These four kinds of denture cleansers have greater influence on the elastic denture base materials than on the heat-curing denture base resins. With the increasing of soaking time, the color aberration and surface roughness of the two kinds of denture materials were increased gradualy after treatment with different denture cleansers, and the values were ranked as follows: NaClO > Efferdent > Polident overnight > Polident partial and water. To conclude, denture cleansers can induce the changes in denture surface roughness and color stability of heat-curing denture base resins and elastic denture base materials. NaClO exerts the strongest effect, followed by Efferdent and Polident overnight, and Polident partial exhibits the weakest effect.

Ecologic studies are widely used in all fields of public health on account of accesibility of data. However, two problems related to these studies have been brought up. The first is ecological fallacy occurred in the course of interpreting the ecologic level of exposure-disease associations into individual level. The second is exposure isclassification which leads to serious bias. Nevertheless there is few methodologic study dealing joint effects of the two problems in ecologic study. This study was conducted to suggest an ecologic model not having an ecologic fallacy due to model linkage failure and a methodology for correcting the misclassification bias due to exposure-confounder misclassification. Finally, we suggest a criteria for the ecologic model selection. Main results are as follows: 1. A linear ecologic regression model has a serious ecological fallacy due to model linkage failure and the misclassification bias due to the exposure-confounder misclassification. 2. An interaction ecologic regression model has no ecological fallacy due to model linkage failure, but it is affected seriously by the exposure misclassification. However misclassification bias could be removed mathematically if the information related to the misclassification was known. 3. A log-linear ecologic regression model has an ecological fallacy due to model linkage failure. It is seriously biased as the individual risk ratio are increased, but relatively less affected by the exposure misclassification than interaction ecologic regression model. 4. One of the two ecologic regression model-interaction ecologic regression model and log-linear ecologic regression model- would be selected according to the information of individual risk ratio and exposure misclassification. But using a linear ecologic regression model should be avoided in any circumstance. The above results are only valid in case that there is no other source of ecological fallacy except model linkage failure. Also exposure and confounder are independent each other, measured binary, and having nondifferential misclassification. Since the above assumptions are somewhat strong in considering the real situations of ecologic studies, it is necessary to extend the scope of this study.
