To knock out β-lactoglobulin (BLG) gene and insert human lactoferrin (hLF) coding sequence at BLG locus of goat, the transcription activator-like effector nucleases (TALEN) mediated recombination was used to edit the BLG gene of goat fetal fibroblast, then as donor cells for somatic cell nuclear transfer. We designed a pair of specific plasmid TALEN-3-L/R for goat BLG exon III recognition sites, and BLC14-TK vector containing a negative selection gene HSV-TK, was used for the knock in of hLF gene. TALENs plasmids were transfected into the goat fetal fibroblast cells, and the cells were screened three days by 2 μg/mL puromycin. DNA cleavage activities of cells were verified by PCR amplification and DNA production sequencing. Then, targeting vector BLC14-TK and plasmids TALEN-3-L/R were co-transfected into goat fetal fibroblasts, both 700 μg/mL G418 and 2 μg/mL GCV were simultaneously used to screen G418-resistant cells. Detections of integration and recombination were implemented to obtain cells with hLF gene site-specific integration. We chose targeting cells as donor cells for somatic cell nuclear transfer. The mutagenicity of TALEN-3-L/R was between 25% and 30%. A total of 335 reconstructed embryos with 6 BLG-/hLF+ targeting cell lines were transferred into 16 recipient goats. There were 9 pregnancies confirmed by ultrasound on day 30 to 35 (pregnancy rate of 39.1%), and one of 50-day-old fetus with BLG-/hLF+ was achieved. These results provide the basis for hLF gene knock-in at BLG locus of goat and cultivating transgenic goat of low allergens and rich hLF in the milk.

Objective To study epidemiology, clinical findings, diagnosis and treatment of sepsis caused by Vibrio vulnificus. Method Patientss with Vibrio vulnificus sepsis were collected from 1995 to 2008. The medical records including epidemiological and clinical data were analyzed. Results The male-to-female ratio of 34cases was 4.7:1 and 76. 5% of these patients suffered from chronic liver disease. Most patients occurred from April to October with signs of abrupt fever, characteristic cutaneous lesions, hypotension and progressive multiple organ disfunction syndrome (MODS). The mortality was over 47.1% . The criteria proposed for early diagnosis of Vibrio vulnificus sepsis were abrupt onset with fever during the period from April to November, characteristic cutaneous lesions, such as the most commonly occurred haemorrhagic bullae on the extremities or even extensive necrosis of skin and muscular tissue, progressive hypotension or shock accompanied by MODS, pre-existing liver disease or chronic abuse of alcohol, and consumption of raw seafood or exposure to seawater within 12 week. Early administration of the third-generation cephalosporins with the quinolones in full dosage, aggressive wound debridement,appropriate dermoplasty and supportive care contribute to a better outcome. Conclusions Vibrio vulnificus sepsis progresses rapidly with high mortality. Early diagnosis, rapid treatment with prompt antibiotics and aggressive surgery treatment are very important to improve the outcome.

Objective To study the factors influenceing patients' family members to make own relative fac-tors patients' families making decision on refusal of cardiopulmonary resuscitation (CPR) to the critical patients. Method Data were registered based on Utstein Style of 522 patients aged over 15 years, who subjected to in-hos-pital cardiac arrest(CA) in Department of Emergency of The First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2008. A total of 157 patients' family made refusal decision among the 522 pa-tients, who belonged to the refusal group, and others belonged to the attempt resuscitation group. The associated factors included age, sex, marriage, household register, cause of CA, underlying diseases, capability of activity before CA, life supported with mechanical ventilation, and administration of pressor agents. The refusal decisions were evaluated by using univariate Logistical regression analysis, and then the statistical significant variables were analyzed by using muhivanate Logistical regression analysis. Results Age, household register, cause of CA(car-diac or traumatic),stroke, sudden death, cancer, capability of activity before CA, life supported with mechanical ventilation,and administration of pressor agents were the important factors of making refusal decision (P < 0.01), but sexes or marriage was insignificant related to the refusal decision (P > 0. O5). The independent risk factors re-lated to refusal decision were age (P = 0.034),cancer (P = 0.006),stroke (P = 0.003), and life supported with mechanical ventilation (P = 0.000) in multivariate Logistical regression analysis, but the protective factors were sudden death (P =0.000),cardiac CA (P =0.020) and traumatic CA(P =0.000). Conclusions Age over 60 years, cancer, stroke, and life suppoted with assisted ventilation before CA were factors associated with re-fusal decision making, yet sudden death, cardiac CA and traumatic CA were factors of accepting CPR.

Objective To survey cervical myoelectric signals during craniocervical flexion, neutral and extension postures, and to explore the evidence that proper head position can alleviate cervical muscle fatigue in a lateral recumbent position. Methods Surface electromyography (sEMG) signals were detected from the sternocleidomastoid, upper trapezius and erector spinae muscles of 30 young subjects bilaterally during craniocervical flexion,neutral and extension postures in the left lateral recumbent position. The integrated trace area (IEMG) and median frequency (MF) were estimated. Results The average IEMG of the sternocleidomastoid muscles was significantly lower in flexion than in extension bilaterally. The average IEMG of the erector spinae muscles was lower in extension than in flexion bilaterally, and the difference was again significant. The IEMGs of the upper trapezius muscle showed no significant difference on average in the three postures bilaterally. There was no significant MF difference in any of the muscles. Conclusions The muscles in the cervical back were less activated during craniocervical extension in a lateral recumbent position. A little cranicocervical extension is optimal while resting in a lateral recumbent position.
