Objective In order to explore the roles of TLR2 and TLR4 in the hepatocyte dam- age caused hy hepatitis B virus infection,and to find whether LPS can affect the damage of hepato- cytes pre-and pos-HBV infection,we detected the changes of TLR2 and TLR4 expressions in hu- man hepatocyte lines HepG2 cells and 2.2.15 cells.Methods HepG2 ceils are most similar to normal human hepatocytes and 2.2.15 ceils are HepG2 cells infected with HBV.We selected these two cell lines to study the differences of TLR2 and TLR4 expression between HepG2 cells before and after HBV infection.In this research,both HepG2 and 2.2.15 cells were stimulated with 0?g/ml, 1?g/ml,10?g/ml,100?g/ml,1 mg/ml and 10 mg/ml LPS.Then the expression of protein of TLR2 and TLR4 were examined by immuno-histochemistry(IHC).The cnRNA of HepG2 and 2.2.15 ceils stimulated with 0?g/ml and 10 mg/ml LPS were examined by reversal transcription-pol- ymerase chain reaction(RT-PCR).Thereafter,the apoptosis of HepG2 and HepG2.2.15 cells were examined by flow cytometry(FC),and the expressions of HBsAg and HBeAg of HepG2.2.15 cells tested with Abbott kits.Results IHC and RT-PCR analysis revealed that TLR2 and TLR4 expres- sions could he detected in both HepG2 and 2.2.15 cells.Moreover,without immune activation, TLR2 and TLR4 expressions were higher in the presence of higher concentrations of LPS.FC analy sis revealed that no apoptosis detected in HepG2 ceils stimulated with LPS in this research,but apop- tosis could be detected in 2.2.15 cells when treated with the same factors.Furthermore,the apoptosis ratios increased with the increase of LPS concentrations.When concentrations of LPS were 1?g/ml, 10?g/ml,100?g/ml,1 mg/ml and 10 mg/ml,the apoptosis ratios were 1.94%,3.03%,3.50%, 3.72%,5.30%,respectively.Abbott analysis revealed that expressions of HBsAg and HBeAg of 2.2.15 cells stimulated with LPS were lower than those not stimulated with LPS.Conclusion HBV can affect the expressions of TLR2 and TLR4 in HepG2 cell lines.LPS can lead 2.2.15 cells to apop- tosis but not HepG2 cells.Although LPS cannot damage normal hepatocytes,it might aggravate hep- atocytes damage when their microenvironment was changed by HBV infection.

OBJECTIVETo investigate surgical outcomes of strip nail internal fixation with bone graft in treating tibial plateau fracture.

METHODSFrom May 2012 to May 2014,36 patients with tibial plateau fracture were retrospectively analyzed, including 25 males and 11 females with an average age of 43.5 (ranged from 17 to 65) years old. The time from injury to operation ranged from 3 to 10 days with an average of 5.8 days. All patients were treated with L-shaped and T-shaped strip nail internal fixation with bone graft. It was evaluated by the Knee Functional therapy assessment method of the Special Surgical Hospital of American at final following-up. Varus angle, caster angle and femorotibial angle were recorded and compared at 3 days and 1 year.

RESULTSOperative time was (2.2 ± 0.6) h on average, blood loss was (310.5 ± 36.2) ml on average, hospital stay was (14.8 ± 2.7) days on average. Thirty-six patients were followed up from 12 to 30 months with an average of 18.2 months. Fracture healing time ranged from 4 to 8 months with an average of 6.2 months. The difference is not significant among varus angle, caster angle and femorotibial angle at 3 days and 1 year. According to the knee functional therapy assessment method of the Specialized Surgical Hospital of American, 18 cases got excellent results, 13 good, 4 moderate and 1 poor.

CONCLUSIONStrip nail internal fixation with bone graft for the treatment of tibial plateau fracture could effectively prevent the joint surface from secondary collapse, and achieve anatomic reduction, stable fixation and earlier functional exercise in further to get satisfied clinical effects.

Objective To investigate the changes of serum glycocholicacid(CG),hyaluronic acid(HA),procollagen type Ⅲ(PCⅢ) in neonatal diseases.Method The levels of serum CG,HA and PCⅢ were measured by radioimmunoassay in 46 neonates with different diseases and 20 healthy neonates.Results Serum CG and HA in patients group were significant higher than those in healthy control group(P

Objective To investigate the effect of acupuncture at Sanyinjiao with functional magnetic reso- nance imaging(fMRI),analyse the regulating effect of the acupoint Sanyinjiao on various brain areas,explore the mechanisms of Sanyinjiao(SP.6) acupuncture in treating diseases.Methods Eight right-handed healthy volun- teers were scanned at 1.5 Tesla magnetic resonance imaging scanner while they were aeupunctured at the right Sany- injiao acupoint.Image data were co-registered to correct head motion,spatial normalization and deconverlution analy- sis were conducted.Functional activation maps were generated.Results There observed certain activation in both sides of medial frontal gyrus,right middle frontal gyrus,left inferior frontal gyrus,both sides of paracentral lobule, precentral gyrus and postcentral gyrus,left inferior parietal lobule,both sides of preeuneus,right middle temporal gy- rus,right cingulated gyrus,posterior cingulated gyrus,both sides of superior temporal gyrus,transverse temporal gy- rus,insula and thalamus.Conclusion Acupuncturing the Sanyinjiao can lead to the functional changes in parietal lobe,frontal lobe,temporal lobe and insula,precuneus,cingulated gyrus,thalamus,which are closely related to the therapeutical effects of Sanyinjiao.The phenomenon that needling Sanyinjiao can activate certain brain areas proved the correlation between acupoint and corresponding brain cortices.

Objective To determine chromosomal localization of the primary gout susceptibility gene in a pedigree.Methods The clinical data and the peripheral blood samples were collected in the pedigree members and the genomic DNA was extracted from peripheral blood.A genome-wide screening was performed using 400 micro-satellite DNA markers in this family,and linkage analysis was used to determine the chromosomal location of the primary gout susceptibility gene.Results Linkage analysis showed that the maximum LOD score reached 1.50 at marker D4S1572 (at recombination fraction?=0.00).Conclusion Since D4S1572 is localized at 4q25,the primary gout susceptibility gene of this pedigree is localized at 4q25.

Objective To evaluate the efficacy and safety of ESHAP regimen,as a salvage regimen, in treating patients with relapsed or refractory aggressive NHL.Methods 38 patients with relapsed or refrac- tory aggressive NHL were selected to be treated by ESHAP regimen.Results The 38 patients received ES- HAP regimen with a range of 2～6 cycles. The total RR was 55.3 % with complete response(CR)rate of 26.3 %.The major toxicity was myelosuppression with infection,which was tolerable.Conclusion ESHAP regimen is one of safe and effective salvage regimens for the patients with relapsed or refractory aggressive NHL.
