China Pharmacy 2017;28(6):766-769
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.
3.Surgical treatment for 70 cases chronic lymphocytic thyroiditis
Journal of Endocrine Surgery 2010;04(6):394-395,408
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.

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.

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.

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.
