Objective To evaluate the effects of preventing and treating delayed gastric emptying (DGE)in the patients with pylorus preserving pancreaticoduodenostomy(PPPD).Methods The clinical data about PPPD from 1992～2000 were analyzed retrospectively.Results The incidence rate of DGE was 50%,among which gastrostomy was performed in 2/2 cases and not performed in four tenths.Comparing gastric decompression through noses with gastrostomy,the function of gastric wriggle recovered ahead of seven to fifteen days in the former group.Conclusion The incidence rate of DGE in the patients with PPPD is very high.Preventive jejunostomy should routinely be taken and the application of the thin silicon rubber tube through nose is very effective to gastric decompression,combining the traditional Chinese medicine with western medicine.

To get specific scFv (Single-chain fragment variable) antibody against soluble Abeta1-42(Amyloid-beta) oligomers, we constructed a human single-chain Fv (scFv) antibody library by phage display technology. Using RT-PCR, we amplified the variable heavy (VH) and variable light (VL) genes from peripheral blood lymphocytes (PBL). Then we obtained the scFv fragments through SOE-PCR, and the scFv fragments were cloned into the vector pCANTAB5E and electroporated into competent Escherichia coli TG1 cells. Consequently, a scFv phage display library containing 2.5 x 10(9) clones was constructed. The recombinant phagemids were rescued by reinfection of helper phage M13K07. Recombinant phages specific for Abeta1-42 oligomers were enriched after four rounds of biopanning and the antigen-positive clones were selected from the enriched clones by phage ELISA. Positive clone B19 was used to infect E. coli HB2151 to express soluble scFv antibody. SDS-PAGE and Western blotting analysis showed that the soluble scFv B19 antibody was expressed successfully and could bind specifically to Abeta1-42 trimer and protofiber. The specific scFv against Abeta1-42 oligomers can be used in the therapeutic research on Alzheimer's disease.

Carpal tunnel syndrome(CTS)is one of the most common peripheral nerve entrapment disorders,the elevated pressure in the carpal tunnel,high-intensity activities and obesity are the main causes,and the patients with mild to moderate CTS are more prevalent.The main pathogenesis of CTS involves the increasing of carpal tunnel pressure and impaired local blood oxygen supply leading to reduced nerve conduction.Currently,the clinical treatment methods for mild to moderate CTS mainly include surgical and nonsurgical treatments.Nonsurgical treatment is the preferable choice for the patients with mild to moderate CTS.The western medical treatment primarily rely on oral medications,but their long-term use is limited due to the certain adverse effects;the local blockade and extracorporeal shock wave therapies show better efficacy for the patients with frequent activities and severe symptoms;the traditional Chinese medicine treatment also becomes a choice for some CTS patients due to their advantages of less pain,lower medical costs,and significant effectiveness.This study reviews the recent advancements in the pathogenesis and treatment of mild to moderate CTS,in order to design the personalized treatment methods for the mild to moderate CTS patients based on their specific conditions in clinical settings and provide the references for precise treatment of the mild to moderate CTS patients.

OBJECTIVE To generate hemophilia A (HA) patient-specific inducible pluripotent stem cells (iPSCs) and induce endothelial differentiation. METHODS Tubular epithelial cells were isolated and cultured from the urine of HA patients. The iPSCs were generated by forced expression of Yamanaka factors (Oct4, Sox2, c-Myc and Klf4) using retroviruses and characterized by cell morphology, pluripotent marker staining and in vivo differentiation through teratoma formation. Induced endothelial differentiation of the iPSCs was achieved with the OP9 cell co-culture method. RESULTS Patient-specific iPSCs were generated from urine cells of the HA patients, which could be identified by cell morphology, pluripotent stem cell surface marker staining and in vivo differentiation of three germ layers. The teratoma experiment has confirmed that such cells could differentiate into endothelial cells expressing the endothelial-specific markers CD144, CD31 and vWF. CONCLUSION HA patient-specific iPSCs could be generated from urine cells and can differentiate into endothelial cells. This has provided a new HA disease modeling approach and may serve as an applicable autologous cell source for gene correction and cell therapy studies for HA.

The acupoint effect of Sanyinjiao (SP 6) and Xuanzhong (GB 39) as well as the internal relation of Sanyinjiao (SP 6)-Xuanzhong (GB 39) were analyzed in this paper to explore the relationship between opposite acupoints and acupoint effect. It was found both Sanyinjiao (SP 6) and Xuanzhong (GB 39) had acupoint effects, and the two acupoints had close relationship in acupoint effects (specificity along meridian and specificity of acupoints), acupoint-meridian relationship (anatomical locations, meridians and organs, indications). It is indicated the opposite acupoint of Sanyinjiao (SP 6)-Xuanzhong (GB 39) had related aspects in acupoint effects, which is related with acupoint effect through specificity and relationship of acupoint-meridian.
