OBJECTIVE To study the phenomenon of hepatitis B surface antigen(HBsAg) and antibody(HBsAb) both positive in blood samples.METHODS Using electro-chemo-luminescence immune system E170 to detect HBsAg and HBsAb in clinical samples and retest the both positive cases by another two reagents for HBsAg and another three reagents for HBsAb.RESULTS All 7332 samples showed 140 both HBsAg and HBsAb positive(1.9%) and 73 of them were retested for HBsAb by another three reagents which gave altogether 24 positive results,which was not related to each other.Those gave higher HBsAb value by E170 showed higher positive rate by Abbott reagent.CONCLUSIONS HBsAg and HBsAb both positive results are not rare.It may be due to the interactions between the patient and the infected hepatitis B virus.Besides,the quality of reagents and correct lab operating procedures may also affect the test results.

Objective To study the effects of the Chinese herbal compound (Erzhiwan, Shixiaosan and combined formula) on cholestasis-induced liver fibrosis rat’s uPA. Methods Bile duct ligation method was used to make the model of cholestasis-induced liver fibrosis. One week after the operation, the rats were randomly divided into five group (model group, UDCA group, Erzhiwan group, Shixiaosan group and hefang group). Each medicine intervention group was given corresponding medicine by intragastric administration. Sham and model group were given sodium chloride with equal dosage. At the end of 4th week, all rats were sacrificed and sampled. General state of health, hepatic function (ALT, AST, ALP, TBil) and pathological histology of hepatic tissue were recorded and measured. Results Compared with the sham group, the level of ALT, AST, ALP, TBil and the degree of liver fibrosis in model group were advanced significantly. Compared with model group, three Chinese herbal compound decreased serum level of ALP, ALT and AST (P

An international symposium on the standard surgical treatment of morbid obesity and type 2 diabetes mellitus was held in Florida, USA in March 2011. An expert panel from all over the world attended the meeting. The expert panelists discussed and established International Sleeve Gastroectomy Expert Panel Consensus Statement : best practice guidelines based on experience of more than 12,000 cases, which made a very commendable attempt in standardized surgical pathway of sleeve gastroectomy. Based on clinical experience over 10 years and the understanding of the consensus , this paper discusses the learning curve, preoperative preparation, indications/contraindications, surgical technique, management and prevention of complications, and post operative management.

Glaucoma is the first leading cause of irreversible blindness and the second leading cause of blindness worldwide. Numerous studies have shown that elevated intraocular pressure ( IOP ) is one of the major risk factors for the development and progression of glaucomatous optic nerve damage. However, there have been 50% of primary open-angle glaucoma ( POAG ) patients with typical glaucomatous optic neuropathy in whom the IOP measurements have always been in the normal range, and some patients develop typical glaucomatous optic neuropathy with the well controlled IOP. These phenomena cannot be explained by the theory of high intraocular pressure. The pathogenesis of glaucomatous optic nerve damage in these patients with normal IOP needs to be further discussed. Numerous studies at home and abroad have shown that: 1. the surrounding anatomy of the optic nerve including the IOP, the anatomy and biomechanics of the lamina cribrosa and retrobulbar orbital cerebrospinal fluid pressure may be of importance for the pathogenesis of the POAG;2. patients with normal tension glaucoma had significantly lower cerebrospinal fluid pressure and a higher trans - lamina cribrosa pressure difference compared with normal subjects; 3. patients with ocular hypertension had significantly higher cerebrospinal fluid pressure, however, there is no difference in trans -lamina cribrosa pressure compared with normal subjects. Based on the above research, now we make a review about the research advance of the relation between intracranial pressure and glaucoma optic nerve damage and the available measurements about noninvasive intracranial pressure in clinical in this paper.

Objective Application of Case-based teaching method (CTM) in the class of Experimental Animal Quality Control aims to break the traditional teacher-centered and textbookcentered teaching model,to invoke students' interest and creativity by integrating practice and theory,and to cultivate their capacity in identifying,analyzing and solving problems.Methods According to different requirements of teaching contents,students were organized to discuss practical cases about quality control of experimental animals through problem-centered learning style.Results Students' capacity was enhanced in terms of problem solving with acquired knowledge,and the ability to pursue new knowledge,the intriguing and vivid cases stimulated students' interest,activated classroom atmosphere,and helped improve teaching efficiency.Conclusion Experimental animal quality control is a complicated system; Case-based teaching method leads to higher efficacy of the course of Experimental Animal Quality Control.
