Toll-like receptor 4 (TLR4), the natural receptor of lipopolysaccharide(LPS), plays an important role in the regulation of acute inflammation, intracellular signal transduction and cell apoptosis. TLR4 over expresses in both acute inflammation and fibrotic tissues, which suggests that TLR4 may be essential in acute inflammation and subsequent fibrosis. Nowadays, some progress has been made in the exploration of TLR4 in pathogenesis and treatment of liver cirrhosis and pulmonary fibrosis. TLR4 may become a new target in the treatment of human fibrotic diseases including liver cirrhosis and pulmonary fibrosis. The research status of TLR4 in human fibrotic diseases and its future development are reviewed in this paper.

Objective To investigate the clinical effects and safety of combination of open and laparoscopic surgery in treatment of elderly patients with gallbladder stones combined with common bile duct stones. Methods 140 elderly patients with gallbladder stones combined with common bile duct stones from May 2014 to May 2015 were randomly divided into control group (65 patients) with traditional open surgery and observation group (65 pa﹣tients) with combination surgery; then compared the perioperative clinical indicators, the total removal rate of stone, the postoperative analgesic used rate and postoperative complications incidence of the two groups. Results The oper﹣ation time, intraoperative blood loss volume, the exhaust time for first time and hospital staying time of observation group was significantly better than control group (P< 0.05). There was no significant difference in the total removal rate of stone between the two groups (P> 0.05). The postoperative analgesic used rate of observation group was sig﹣nificantly lower than control group (P< 0.05). The postoperative complications incidence of observation group was significantly lower than control group (P< 0.05). Conclusion Compared with traditional open surgery, combination surgery in treatment of elderly patients with gallbladder stones combined with common bile duct stones can efficient﹣ly shorten the operation time, speed up the recovery process, reduce the degree of trauma and postoperative pain and helpful to prevent the postoperative complications.

The effect of recombinant human phospholipase D2(rhPLD2)in vivo was investigated on the secretion of serum glycosyl phosphatidylinositol-specific phospholipase D(GPI-PLD)in guinea pigs of chronic asthma．Ater treating the guinea pigs attacked by chronic asthma with rhPLD2,the GPI-PLD activity detection was canrried out by phase separation of human placental alkaline phosphatase in Triton X-114．Compared with the healthy guinea pigs(NS group),the serum GPI-PLD in the guinea pigs of chronic asthma are much higher than that of control groups,P≤0．01．Our results showed that rhPLD2 could significantly reduce the secretion of GPI-PLD when the guinea pigs were attacked by chronic asthma．

Objective Direct amplification of length polymorphism (DALP) as a new molecular marker was used to establish a set of stable DALP reaction system for the plants of Rhodiola L. Methods Some significant parameters of DALP reaction procedure were investigated and optimized by taking the DNA genome for the plants of Rhodiola L. as template. Results The reaction system was : 20 ?L reaction system containing 2. 5 mmol/L Mg2+ , 1. 25 mmol/L dNTPs, 60 ng DNA template, 1 ?L 5 pmol/L selective primer, 3 ?L 5 pmol/L reverse primer, selective primer: reverse primer is 1 : 3, and 2 U Taq DNA polymerase. Amplification program is 95℃ pre-denatured for 5 min, 94℃ denatured for 30 s, 50℃ annealed for 30 s, 72℃ extending for 1 min; after 30 cycles, and then 72℃ extending again for 10 min to the end of PCR reaction. Conclusion This DALP reaction system is efficient to identify the species and local populations for the plants of Rhodiola L. repeatedly with the stronger stability and reliability.

AIM:ToinvestigatetheeffectofIkarosisoformsontheproliferationofhumanovariancancerSK-OV3 cells.METHODS:Three isoforms of Ikaros, IK1, IK2 and IK6, were transfected into ovarian cancer SKOV3 cells. CCK-8 assay and cell counting were used to detect the effects of Ikaros isoforms on the proliferation of SKOV 3 cells.The cell cycle was analyzed by flow cytometry .The cell cycle-related proteins were detected by Western blot .RESULTS:IK1 and IK2 expression inhibited SKOV 3 cells proliferation .Flow cytometry analysis indicated that IK 1 and IK2 induced SK-OV3 cell cycle arrest at the G 1 phase.IK6 isoform exerted no obvious effect on the proliferation or cell cycle of SKOV 3 cells.Compared with control EV group , IK1 group and IK2 group showed a dramatic elevation in the expression of the cell cycle inhibitor p21, along with a substantial decrease in the expression of the cell cycle inducers cyclin D 1 and cyclin D2, which did not change in IK 6 group.CONCLUSION:IK1 and IK2 significantly inhibit the proliferation of ovarian cancer SKOV3 cells and induce cell cycle arrest at G 1 phase by regulation of cell cycle-related proteins cyclin D1, cyclin D2 and p21, while IK6 isoform exerts no obvious effect on the proliferation and cell cycle of SKOV 3 cells.

Objective To understand the mortality rate and cause of the injury in Hebei province in order to provide scientific theoretical basis for drawing up effective prevention measures.Methods The injury deaths data was collected from 18 surveillance spots in Hebei province during 2004—2005,and the injury was classified with ICD-10 and the corresponding mortality rates were calculated.Results The average injury mortality rate was 54.02/100 000(the age-adjusted rate was 51.62/100 000).It was the 5 th-ranked cause of death.The leading five causes of injury were traffic injury by motor vehicles, traffic injury by non-motor vehicles,suicide,poisoning and fall,which accounted for 23.96%,22.05%,13.10%,11.99%, 5.62%,respectively.The average injury mortality rate in rural(58.48/100 000)was higher than in urban(31.60/100 000)(?~2= 255.82,P

Objective To investigate the effects of Shen-fu injection on pulmonary contusion rabbits. Meth-ods Sixteen rabbits were randomly divided into 2 groups: the treatment group (Shen-fu group) and the control group. The animals were induced the pulmonary contusion models. After 60min, the animals in Shen-fu group re-ceived Shen-fu injection received 5 ml/kg, and those in control group 5 ml/kg LRS. The animals were killed six hours later, the right lung tissue wet-to-dry (W/D) ratio and myeloperoxidase (MPO) activity were obtained,the pro-tein expression of nuclear factor-kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) were also detec-ted. Results The lung tissue W/D, MPO, and the protein expression of NF-κB and ICAM-1 were decreased evi-dently in Shen-fu group (P<0. 01). The morphologic and ultrastructural damages in Shen-fu group were milder than in control group. Conclusion Shen-fu injection is effective on pulmonary contusion rabbits.

Objective To explore the effect of early stage of comprehensive lung rehabilitation on cervical spinal cord injury in patients with mechanical ventilation.Methods The patients with cervical spinal cord injury admitted from January to December 2015 were selected as the control group which was treated with routine nursing measures.The patients with cervical spinal cord injury admitted from January to December 2016 were selected as the treatment group,which received early stage lung rehabilitation measures.We compared two groups of patients in the using time of breathing machine,the total length of hospital stay and pulmonary infection rate.Results The duration of mechanical ventilation and hospitalization days in the control group were(13.98±11.11),(25.10±16.98)d,which were higher than those in treatment group[(7.23±4.94),(16.26±6.41)d](P<0.05).The infection rates of control group and treatment group were 76.19％and 52.38％respectively,and the difference was significant(P<0.05).Conclusion In the early stages comprehensive pulmonary rehabilitation measures for mechanical ventilation in patients with cervical spinal injury can shorten the breathing machine use time and the total hospitalization days,and reduce pulmonary infection rate.
