Objective To investigate the influences in perioperative variations in serum levels of hepatitis B virus (HBV) DNA in patients with HBV-related hepatocellular carcinoma (HCC),and to observe the differences in postoperative recovery of liver function between the antiviral treatment group and the non-antiviral treatment group of patients.Methods From Feb.2012 to Nov.2012,55 patients whose preoperative serum levels of HBV DNA were below the recommended level of antiviral treatment were included into the study.The serum levels of HBV DNA,IL-6,IL-10 and IL-27 preoperatively and on postoperative day 3 were measured.Using the postoperative serum levels of HBV DNA,the patients were divided into 2 groups:the high level group and low level group.Patients in the high level group received antiviral treatment,but the low level group did not.The changes in preoperative and postoperative liver function and other data of the patients were recorded and analyzed by the SPSS 13.0 software.Results (1) The reactivation rate of serum HBV DNA in the HBsAg-positive HCC patients was 45％ (25/55).In patients with a preoperative HBV DNA level ＜ 1 × 104 IU/ml the postoperative HBV reactivation rate was up to 76％ (19/25).(2) Logistic regression analysis showed tumor diameter (P=0.037,0.006) and injecting anhydrous alcohol into the resection margin (P=0.004) were independent risk factors of postoperative HBV reactivation.(3) Postoperative serum IL-10 elevation was associated with HBV reactivation (P=0.001).On the contrary,serum IL-6 level elevation was associated with HBV reactivation (P＜0.01).(4) When compared with the low level group,postoperative serum alanine aminotransferase,total bilirubin and albumin in the high level group showed no significant difference (P＞0.05).Conclusions Hepatectomy could reactivate HBV replication during the perioperative period.A close monitoring of HBV DNA during the perioperative period was necessary,especially in patients with low HBV DNA levels.The tumor diameter and injecting anhydrous alcohol into the resection margin were independent risk factors of postoperative increase in HBV DNA.Changes in serum IL-10 and IL-6 levels after hepatic resection might be related to the elevation of HBV DNA level.In addition,reactivation of HBV did not aggravate damages in postoperative liver function.Antiviral treatment did not promote recovery of liver function in the early stage.

High altitude retinopathy ( HAR ) refers to the body which can't adapt to the hypobaric hypoxia environment at high altitude leading to retinal diseases, which typically manifested as retinal hemorrhages, optic disc edema and cotton wool spots. With the development of high altitude medicine, HAR become a hot topic of eye research in recent years. New researches show a significantly higher incidence of HAR, and HAR has a close contact with acute mountain sickness, high altitude cerebral edema and high altitude pulmonary edema. A further study in pathogenesis and prevention measures of HAR will promote the prevention of altitude sickness. Traditional Chinese Medicine has achieved good effects in the prevention of altitude sickness, but the effect and mechanism of herbs on HAR has not been reported. Through read and summarize the relevant literatures and reports, the author will give an overview of the research advances on HAR's pathogenesis and application of Traditional Chinese Medicine.

Objective To construct the serine protease gene(sprE)mutant and to study the pathogenicity of sprE gene of Enterococcus faecalis.Methods Recombinant suicide vector pCQ001 of Enterococcus faecalis with pTX4577,was constructed.Then,created isogenic sprE-deficient mu- tant(*sprE)by allelic replacement was constructed.Moreover,the growth ability and the virulence of the mutant were compared with those of the wide type in vitro and in vivo respectively.A mouse peritonitis model and a rabbit endocarditis model were utilized in the study.Results The *sprE was selected by kanamycin and identified by polymerase chain reaction(PCR),pulsed field gel electropho- resis(PFGE)and Southern blot.The evidences showed that the sprE gene had a major role in helping bacteria to resist the elevated temperature and oxidative stress.The virulence of mutant decreased af- ter sprE gene was knocked out.Conclusions The *sprE of Enterococcus faecalis is constructed suc- cessfully,sprE gene is important in the pathogenesis of Enterococcus faecalis,which probably is a major virulence factor of Enterococcus faecali.

IMAC was used as preparative regimens.Results All patients were engrafted successfully.The disease-free survival could be Ben in 8 cases(57.1%),the median disease-free survival duration were 26(8-72)months and no treatment-related mortality was present.Conclusion This study suggested that addition of Idarubicin to the MAC preparative regimens Was safe,effective and feasible for patients with acute myeloid leukemia,and may improve disease-free survival and overall survival.

Objective To investigate the approach and safety of minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi. Methods Clinical data of 21 cases with symptomatic caliceal diverticular calculi were retrospectively reviewed. Twelve females and 9 males aged 22 to 57 years old. The average diameter of caliceal diverticulum was 3.7 cm (2.5-7.0 cm) and average diameter of calculi was 2.3 cm (0.8-3.5 cm). The patients underwent flexible ureteroscopic lithotripsy, PCNL or mPCNL, laparoscopic techniques and laparoscopy-assisted transperitoneal PCNL, respectively. Four cases underwent flexible ureteroscopic lithotripsy. PCNL (2 cases) or mPCNL(5 cases)were performed in 7 cases. Nine cases underwent laparoscopic techniques. Laparoscopyassisted transperitoneal PCNL was performed in 1 case. Results The operations were performed successfully in 21 cases. No case need to transfer to open surgery during the operation and no major complications like perforation or organic injury were noted. One case with iatrogenic arteriovenous fistula of the kidney after 1 week postoperative was cured by delayed hemorrhage 2 days later, while clinical symptoms of 2 cases with residue calculi relieved. 19 cases without residue calculi were followed up for 6 to 12 month without recurrence. Conclusions After handling indication of treatment efficiently and creating advisable therapeutic decision-making, minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi appears to be effective and safe.

Aim: To investigate a new type wound dressing,basic fibroblast growth factor(bFGF)/collagen com-posite sponge,and conduct its pharmacological studies in vitro and in vivo.Methods: bFGF/collagen composite sponge was prepared using fresh pig skin and bFGF.The sponge's physicochemical properties were studied.MTT assay was used to detect the proliferation effect of the sponge extract on 3T3 cells.Delayed allergy of the sponge was tested for the assurance of its biosafety.Results: Results showed that the physicochemical properties of bFGF/collagen composite sponge with high and low doses of bFGF have no significant difference from those of blank collagen sponge.SDS-page analysis indicated that the composite sponge has apparent strip in 18 kD.It was also found that bFGF/collagen composite sponge was responsible for significant effects on 3T3 cell proliferation in comparison to saline treatement(P <0.01,P <0.05).In the allergy study,during the periods of the induction and stimulation,no allergic reaction was found in bFGF/collagen composite sponge groups with high and low doses of bFGF,while severe reactions and inflammation occurred in positive group(2,4-dinitrochlorobenzene).Furthermore,pathological examination indicated the intact dermal structure and no sign of inflammation.Conclu-sion: The developed sponge has good physicochemical propertis and noticed cellular proliferation without dermal irritation.There is much potential to develop bFGF/collagen composite sponge into a new kind of wound dressing material for clinical use.

Objective To evaluate the effects of sevoflurane on the expression of heparanase ( HPA) and fascin in lung carcinoma cells of mice. Methods Mouse LLC cells were inoculated in the culture plate. After being cultured for 24 h, the cells were equally and randomly divided into 4 groups using a random number table: control group ( group CC) , 1% sevoflurane group ( group Sev1 ) , 2% sevoflurane group ( group Sev2 ) , and 3% sevoflurane group ( group Sev3 ) . Cells in Sev1-3 groups were exposed to 1%, 2% and 3% sevoflurane, respectively, for 4 h, while cells in group CC were not exposed to sevoflurane, and all the cells were then cultured for another 24 h in an incubator. The invasion of cells was determined by Transwell invasion assay, and the invaded cells were counted. The migration of cells was determined by wound healing assay, and cell migration rates were calculated. The expression of HPA and fascin in cells was detected by Western blot. Results Compared with group CC, the number of invaded cells and cell migration rates were gradually decreased, and the expression of HPA and fascin was gradually down?regulated with increasing concentrations of sevoflurane in Sev1-3 groups. Conclusion The mechanism through which sevoflurane inhibits the metastasis of mouse lung carcinoma cells is associated with down?regulated expression of HPA and fascin.

Objective To evaluate the effect of transurethral feedback microwave thermotherapy with the ProstaLund CoreTherm Device(PLFT) in high risk patients with benign prostate hyperplasia (BPH). Methods Sixty-six high risk patients diagnosed with BPH, including aged ≥80 in 32 pa-tients, hypertension in 31 patients, diabetes in 5 patients, heart failure in 8 patients, chronic obstruc-tive pulmonary disease in 8 patients, cerebral infarction in 11 patients, fracture, amputation or joint stiffness unsuitable for lithotomy position in 3 patients, abnormal blood coagulation in 4 patients, pan-creatitis in 2 patients, cardiac arrhythmia in 6 patients and malignant tumor in 3 patients, were treated with PLFT using individual power at urethral local anesthesia, resulting in coagulation necrosis in 15%-30% of prostate tissue around urethra. Meanwhile, real-time monitoring the temperature of prostate and the tissue around it was used. All patients were evaluated by comparing volume of pros-tate, maximal urinary flow (Q_max), international prostate symptom score (IPSS) and quality of life questionnaire (QOL) in pre-treatment and three months after respectively. Results All of patients well tolerated PLFT. There was bleeding lightly, infection lightly and temporary incontinence. There was no severe surgical complication. After three months, the volume of prostate reduced from 62. 2 ml to 44.5 ml; IPSS decreased from 23. 4 to 11.7; QOL decreased from 4.5 to 2.4; Q_max rised from 4, 2 ml/s to 11.2 ml/s. All differences reached significance. Conclusion PLFT is one of effective and safe treatments for patients with BPH especial BPH complicating with severe conditions.
