Objective To explore the operative cooperation and nursing points of holmium laser lithotripsy under percutaneous nephroscope. Methods A retrospective study was carried out to investi-gate the operative cooperation and nursing of 38 patients receiving holmium laser lithotripsy under percuta-neous nephroscope in our hospital from March 2006 to August 2007. Results Stones were completely cleared in 31 patients at first holmium laser lithotripsy,in 5 patients at second holmium laser lithotripsy,in 2 patients at third holmium laser lithotripsy. One patient complicated with water intoxication and septicemia. Operation time ranged from 50 to 190 minutes,blood loss volume reached 50 to 200 ml with a average of 100 ml.No blood transfusion was needed during the operations and no secondary hemorrhage was seen postoperation. Double J catheter was inserted and indwelled for 30 to 60 days with a average of 38 days. Postoperative follow-up was satisfying. Conclusions Holmium laser lithotripsy under pereutaneous nephroscope possesses the advantages of little trauma,hemorrhage and complication and quick recovery.It is the best choice for treatment of calculus in urinary system.

Objective To discuss diagnosis and surgical treatment for chronic lymphocytic thyroiditis (CLT). Methods Records of 70 patients who were diagnosed as CLT from 2005 to 2009 were retrospectively reviewed. They were divided into two groups according to pathological results. Results There were 6 patients of CLT accompanying with papillary carcinoma. The rest 64 patients were diagnosed as CLT accompanying with benign nodules. All cases were confirmed by pathology and treated with operation. Conclusions Coexistence of nodules which can not be excluded from carcinoma is the main reason for surgical treatment in case of CLT. CLT patients especially for those associated with single nodule and/or microcalcification inside nodules should be given surgical treatment. The operative method depends on pathological results during operation.

OBJECTIVE:To observe the efficacy and safety of rebamipide triple therapy in the treatment of gastric ulcer with bleeding. METHODS:130 patients with gastric ulcer with bleeding were randomly divided into control group(65 cases)and obser-vation group(65 cases). Control group received Omeprazole enteric-coated capsule 20 mg,orally,twice a day+Aluminum magne-sium carbonate tablet 500 mg,orally,once a day;observation group was additionally received Rebamipide tablet 0.1 g,orally,3 times a day. They were treated for 12 weeks. Clinical efficacy,remission time of belching,abdominal pain,bloating,hematemesis/hematochezia,clinical symptom score before and after treatment,rebleeding and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,remission time of symptoms and signs were significantly shorter than control group,the incidence of rebleeding was significantly lower than con-trol group,with statistical significances (P<0.05). Before treatment,there was no significant difference in the clinical symptom score (P>0.05). After treatment,the clinical symptom scores in 2 groups were significantly lower than before,and observation group was lower than control group,with statistical significances (P<0.05). And there was no significant difference in the inci-dence of adverse reactions (P>0.05). CONCLUSIONS:Rebamipide triple therapy shows obvious short-term efficacy in the treat-ment of gastric ulcer with bleeding,which can effectively improve patients'gastrointestinal symptoms,reduce rebleeding risk,and does not increase the incidence of adverse reactions.

Good patient care requires accurate and comparable laboratory test results. To achieve standardization, a reference system consisting of a hierarchal framework of validated and reliable analytical methods linked by reference materials must be in place. Supported by national and municipal research programs, construction of reference systems has been pursued and progress been made. Candidate reference methods have been set up or developed for some important tests, and the methods have been used in the calibration or evaluation of routine methods, study of commutability of control materials and characterization of reference materials. Phenomenal roles of reference systems are expected in diagnostic reagent manufacturing, internal quality assurance and external quality assessments.

Objective To probe the feasibility, indications and efficacy of damage control orthopedics (DCO) in treating severe multiple injuries combined with fractures. Methods A retrospective analysis was done on the clinical data of 31 patients with severe multiple injuries combined with fractures treated by DCO from 1998 to 2008. Results Of all patients, 18 patients were combined with pelvic fractures and hemorrhage. Bilateralis hypogastric artery ligation was performed early in 17 patients and nonage pelvis external fixation was performed in 12. Eleven multiple trauma patients combined with femoral fractures received primary debridement and temporal external fixation for further definitive internal fixation. Two patients with spinal fractures combined with spinal cord compression received primary simple decompression. All patients received resuscitation in ICU for average 4.3 days (1-11 days). There was one death due to hemorrhagic shock. Conclusions DCO well conforms to pathophysiological character of the wounded. Early DCO and later integrated treatment are key to enhancement of the survival rate of the multiple trauma patients.

The major immunogenic proteins (Ems,E2 and NS3) of classical swine fever virus (CSFV) (Shimen strain) were expressed in E.coli and purified by affinity chromatography.The recombinant antigens were applied to develop multiple enzyme-linked immunosorbent assays (ELISAs) for the detection of specific antibodies in pig sera.Optimum cut-off values were determined by receiver operating characteristic (ROC) analysis after testing 201 sera of vaccinated pigs and 64 negative sera of unvaccinated piglets.The multiple ELISAs were validated with 265 pig sera yielding high sensitivity and specificity in comparison with the virus neutralization results.The results demonstrated that multiple ELISAs can be a valuable tool for the detection of CSFV infection and serological surveys in CSFV-free countries or for the evaluation of the antibody responses in pigs induced by a live attenuated C-strain vaccination.

Roles of reference method in clinical biochemistry were introduced.Reference method is an important component of the reference system.Reference methods are primarily used for the establishment and assurance of the traceability of measurement results through calibrating and evaluating routine methods and assigning values to reference materials.Calibration biases and non-specificities of routine methods and the commutability of reference materials are the major issues in the standardization of clinical biochemistry.Standardization also requires availability of commutable reference materials.Reference methods are irreplaceable tools to identify the issues and to characterize reference materials.

Objective To evaluate the prognostic value of combining postprocedural fibrinogen with high-sensitivity C-reactive protein (hs-CRP) in first time ST elevated myocardial infarction (STEMI) patients who had underwent successful primary percutaneous coronary intervention (PCI).Methods A total of 183 consecutive patients who had their first acute STEMI attack and underwent successful primary PCI were enrolled. Fibrinogen and hs-CRP levels were measured within 12 hours after PCI. All patients were followed up for 2 years. The primary end point was death of any cause. The secondary end point was a combined end point of death, non-fatal MI, heart failure (NYHA Ⅲ~Ⅳ),myocardial ischemia confirmed by stress test and revascularization. Results Postprocedural fibrinogen level correlated with hs-CRP level linearly (r=0.452, P

Objective To study the clinical application of ureteral grasping forceps in ureteroscopic operations.
