Objective To discuss the effect of the modified structure of oxygen equipment on oxygen inhalation effect of patients receiving oxygen therapy.Methods The structure of oxygen equipment was modified.and 80 patients who required oxygen therapy were divided into the modified group and the non-modified group according to odd and even number of hospital admission sequence randomly with 40 patients in each group.The modified group used the modified oxygen equipment,the non-modified group used traditional one.The differences of respiration,heart rate and blood oxygen saturation rate between the two groups before oxygen inhalation,30 minutes and 2 hours after oxygen were compared.Results There was no significant difference in the respiration,heart rate and blood oxygen saturation rate between the two groups.Conclusions The modified oxygen equipment doesn't affect the oxygen therapy effect of patients,besides,it avoids the problems of pollution and the complicated disinfection procedure of the structure of the humidifier bottle,fluid and breathing vessel of the traditional equipment.

Objective To evaluate the effect of perioperative enteral immunotrition(IMPACT) on liver regeneration in cirrhotic rats with hepatectomy. Methods Forty-eight cirrhotic rats were randomly divided into two groups: Group A, perioperative standard enteral nutrition group(n=24), receiving standard enteral nutrient NUTRISON during hepatectomy. Group B, perioperative enteral immunonutrition group(n=24), receiving enteral immunonutrient IMPACT after hepatectomy. According to the different time of taking specimens, each group was separated into four subgroups, each subgroup had six rats. The rats in the two groups received equal daily nutritional supplement intragastrically, which was 690kJ/kg per day. Before the 68% hepatectomy, the rats were fed with enteral nutrient for 8 days, and after operation were fed until the day of taking specimens. On the day before hepatectomy and 1st, 4th and 8th postoperative day(POD), MI (mitotic index) of liver cell and PCNA (proliferating cell nuclear antigen) labeling index of hepatocyte were determined. Results MI increased significantly in both group on 4th and 8th postoperative day(P

Objective To study the effect of intracerebroventricular(icv) injectionon acetylcholine(ACh) on the elecric activities of pain-related neurons in the hippocampal CA1 area of rat.Methods Trains of the electric impulses applied to the right sciatic nerve were used as noxious stimuli.The discharges of neurons were led out by extracellular recording method with glass microelectrodes.Results Icv injection of ACh(20?g/10?l) caused an decrease of the evoked discharge frequency of pain-excited neurons(PEN) and a prolongation latency as well as an increase of the evoked discharge of pain-inhibited neurons(PIN) and a shortening of inhibitory duration.Conclusion The response of pain-related neurons in hippocampal CA1 area to the noxious stimulation is weakened by icv injection of ACh,exhibiting analgesic effect.

Objective To explore the feasibility of la pa roscopic total extraperitoneal hernia repair without the use of the balloon diss ector. Methods Laparoscopic total extraperitoneal hernia repai r using no balloon dissector was completed in 10 cases of groin hernia from Nove mber 2003 to April 2004, including 7 cases of indirect inguinal hernia, 1 case o f occult indirect hernia combined with direct inguinal hernia, and 3 cases of di rect inguinal hernia (1 of which was recurrent hernia). Results All the 10 operations were successful. The mean operation time was 69.5 min, t he mean blood loss was 11 ml, the mean postoperative hospital stay was 2.1 days , and the mean duration to normal activities, 5.2 days.Complications included 1 case of disassociated inferior epigastric artery, 1 case of operation in wrong anatomic layer, and 1 case of laceration of the peritoneum, respectively. Follow -up observations for 1~6 months found no recurrence and neuropathic pain. Conclusions Laparoscopic total extraperitoneal hernia repair without the use of the balloon dissector is feasible, safe and effective.

Objective To discuss the feasibility of laparoscopic closure of the internal ring and high ligation of the hernial sac in children with indirect inguinal hernia.Methods Laparoscopic closure of the internal ring and high ligation of the hernial sac was conducted in 21 children with indirect inguinal from January 2003 to December 2004 in this hospital.A 5-mm 30? laparoscope was introduced through the umbilicus.The internal ring and the posterior crus(PC) on the side of hernia were identified.A 3-mm dissection forceps was placed on the midline between the umbilicus and pubic symphysis.At the skin projection of the internal ring on the side of hernia,a round-tip needle with 3-0 Prolene suture grasped by a regular needle holder was passed directly into the abdominal cavity to suture the posterior crus and then penetrate out of the abdomen via the roof of the internal ring through the musculoaponeurotic arch of the transversus abdominis.Then the Prolene suture was cut off,and passed by using the Endoclose device into the extraperitoneal cavity at the skin projection of the internal ring.The dissection was continued from without outward around the sac to encircle the neck and an extracorporeal high circumferential ligation of the sac was finished.Results The operation was successfully completed in all the 21 cases.The operating time was 16~50 min(mean,32.9 min),the postoperative duration in hospital was 1~2 d,and the time to normal activity,1~4 d(mean,1.4 d),respectively.No postoperative bleeding,hematoma of scrotum,or incisional infection occurred.Follow-up checkups in the 21 cases for 1~24 months(mean,15 months) showed no recurrence.Conclusions Laparoscopic closure of the internal ring and high ligation of the hernial sac is a novel,feasible,reliable and effective herniorrhaphy for the treatment of pediatric indirect inguinal hernia.

Bone marrow stromal antigen 2 (BST-2) is a kind of host restriction factor. Since it was discovered to be responsible for the defect in virion release of HIV-1 mutants lacking the accessory gene vpu in 2008, it was thought to mainly restrict the viruses by directly tethering viral particles at the plasma membrane. Recent reports suggest that BST-2 also can inhibit the the release of HBV particles, which are budding in the intracellular vesicles, expanding the antiviral spectrum of BST-2. Futhermore, the machanism that BST-2 used to restrict HBV release in multivesicular bodies (MVBs) is similar to that used to restrict HIV at the plasma membrane. However, HBV have evolved strategies to antagonize the antiviral action of BST-2. There are two different opinions about the antagonist. One is HBV inactivated BST-2 by HBx requiring a hepatocyte-specific environment. Another thought envelope protein HBs counteract the antiviral action of BST-2. In this review, we focus on the current advances in the anti-HBV activity of BST-2.
