Ventral hernia is a very common surgical problem with its incidence gradually increasing due to aging population,and it has significantly threat to quality of life.Laparoscopic hernia repair is a kind of minimally invasive surgery based on tension-free hernia repair,which has become an effective way for treatment of ventral hernia after decades of development.Besides,the classic surgical approaches for adult inguinal hernia include intraperitoneal onlay mesh,transabdominal peritoneal and totally extraperitoneal repairs.However,some related complications including vascular injury and bleeding,postoperative pain,nerve damage,seroma,intestinal obstruction,infection and relapse have been increasingly reported with the extensive applications of laparoscopic ventral hernia repair.Surgeons still need to pay more attentions and take appropriate measures to prevent such events.Complications could be reduced by strictly following the indications of different laparoscopic hernia repair surgeries with a careful consideration of the advantages and disadvantages,understanding their pathogenesis,improving the laparoscopic operation techniques,getting familiar with the local anatomical structures and standardizing the surgical procedures.Establishing a correct and standard surgical training system will further shorten the learning curve of surgeons to promote the progression and development of hernia surgery in China.

This paper reports the optimized electro-transformation parameters of Bacillus thuringiensis plasmid-free mutant strain BMB171 by electroporation, and expressing effect of several cry genes introduced in this recipient. It showed that a highest electro-transformation frequency could be obtained, when SG solution was used as the buffer, and a 10.0V/cm of field strength, one time of pulse as well as a growth phase of recipient cells at the exponential phase (OD650nm value was 0.2~0.3) were selected. The highest of electro-transformation frequency with pHT3101 could reach at 8 ?107 hansformants/?g DNA. The transformation frequencies increased at linear velocity as the concentration increase of pHT3101 from 54.69pg/ml to 3.50?g/mL, then reached saturation afterwards. All plasmids introduced in BMB171 could produce characteristic insecticidal crystal proteins through expression of relevent cry genes carried by them. Meanwhile, these insecticidal crystal proteins could form parasporal crystals, which have characteristic geometric shapes.

BACKGROUND: Long-term radioactive ray accumulation leads to surrounding tissues fibrosis accompanied by limitation of mouth-opening, which seriously affects life quality of tumor patients. OBJECTIVE: To observe pathological change of soft tissues in rats with radiation masseter injury and the level of transforming growth factor β1 (TGF-β1) mRNA expression in vivo.METHODS: A total of 30 Wistar rats were randomly divided into control group (n=10) and radiated group (n=20). Radiated group were radiated with linear accelerator at a dose of 40 Gy. The pathological changes of vessels were observed under light microscope and electron microscope and expression of TGF-β1 was detected by RT-PCR. RESULTS AND CONCLUSION: The microvessel density of radiated group was obviously decreased than that of the control group (P < 0.01), but the mRNA expression of was higher than that in the control group (P < 0.01). It suggests that radiated injury can induce fibrosis to repair the radiated injury.

Objective To evaluate the effect of heme oxygenase-1 (HO-1) protein transduction on acute lung injury in septic rats.Methods Eighteen healthy male Sprague-Dawley rats,aged 7-9 weeks,weighing 210-260 g,were randomly allocated into 3 groups (n =6 each) using a random number table:sham operation group (group Sham),sepsis group (group Sep),and fusion protein PEP-1-HO-1 group (group HO).Sepsis was produced by cecal ligation and puncture (CLP).In group HO,PEP-1-HO-1 fusion protein 0.6 mg was injected via the left iliac vein at 1 h before CLP and 5 h after CLP.The equal volume of normal saline was given instead of PEP-1-HO-1 in Sham and Sep groups.At 12 h after CLP,blood samples were collected from the right common carotid artery for measurement of serum tumor necrosis factoralpha (TNF-α) and interleukin-6 (IL-6) concentrations.The rats were then sacrificed,and lungs were removed for microscopic examination and for determination of wet/dry lung weight ratio (W/D ratio) and malondialdehyde (MDA) content (by thiobarbituric acid colorimetric method).Results Compared with group Sham,the W/D ratio and MDA content were significantly increased,the serum TNF-α and IL-6 concentrations were significantly increased (P＜0.05),and the pathological changes were significantly aggravated in Sep and HO groups.Compared with group Sep,the W/D ratio and MDA content were significantly decreased,the serum TNF-α and IL-6 concentrations were significantly decreased (P＜0.05),and the pathological changes were significantly attenuated in group HO.Conclusion HO-1 protein transduction can attenuate acute lung injury in septic rats,and the mechanism is probably related to inhibition of lipid peroxidation in lung tissues and systemic inflammatory responses.
