Objective:To analyze the relationship between hepatitis B virus(HBV)gene mutation at 1896 in precore region with genotype and replication of HBV and the liver function of patients.Methods:HBV precore 1896 site mutation,the genotype of HBV and serum content of HBV DNA were determined by PCR in 60 patients positive of HBV DNA.Chemiluminescence miacropaticle immunoassay(CMIA)was used for detection of serum HBeAg and HBeAb.Liver function parameters were ob- tained by routine biochemistry method.Results:The alanine aminotransferase(ALT)level in HBV with 1896 site mutation was significantly higher than that in the wildtype virus.Site mutation at 1896 had no correlation with HBeAg,HBV genotype and HBV DNA content.HBV DNA content in patient with genotype C was significantly higher than that with genotype B(P

Objective To systematically evaluate the effect of preoperative transarterial chemoembolization (TACE) on perioperative safety of patients with resectable hepatocellular carcinoma (HCC).Methods Literatures were researched using Chinese Journal Full-text Database,Wanfang database,VIP database,PubMed,Medline from December 1,1994 to May 30,2016 with the key words including “肝细胞癌,肝切除,术前化疗栓塞,经动脉化疗栓塞,liver cancer,hepatocellular carcinoma,liver resection,hepatectomy,transcatheter arterial chemoembolization,transarterial chemoembolization,preoperative” Manual retrieval was also conducted simultaneously.The randomized controlled trials (RCTs) about TACE on perioperative safety of patients with resectable HCC were received and enrolled.Patients undergoing surgery after preoperative TACE were allocated into the case group and patients undergoing first-stage resection were allocated into the control group.Two reviewers independently screened literatures,extracted data and assessed the risk of bias.Count data were described as relative risk (RR) and 95％ confidence interval (CI).Measurement data were represented as standardized mean difference (SMD) and 95％CI.The heterogeneity of the studies was analyzed using the I2 test.Results Five RCTs were enrolled in the Meta analysis,and the total sample size was 430 cases including 212 in the case group and 218 in the control group.Results of Meta analysis showed that there was no statistically significant difference in the hemihepatic resection rate between the 2 groups (RR=0.99,95％CI:0.81～ 1.20,P＞0.05).The combined resection rate of perihepatic organs in the case group was significantly higher than that in the control group (RR=3.42,95％CI:1.91-6.12,P＜0.05).Results of subgroup analysis showed that operation time and incidence of postoperative complications of patients with an average tumor diameter ＞5 cm in the case group were respectively longer and higher than these in the control group (SMD=0.31,RR=1.65,95％CI:0.06-0.57,1.01-2.69,P＜0.05).Conclusion There is no obvious effect of preoperative TACE on resectable HCC,and it can evaluated combined resection rate of perihepatic organs,operation time and incidence of postoperative complications of patients with resectable HCC and an average tumor diameter ＞ 5 cm,and also reduce the perioperative safety.

Objective To evaluate the short-term efficacy of total hip arthroplasty combined with subcutaneous osteotomy in the treatment of CroweⅣ hip dysplasia (DDH).Methods From March 2012 to March 2015,14 patients (16 hips) underwent total hip arthroplasty with femoral distraction osteotomy S-ROM femoral stem prosthesis.And we observed its recent efficacy.Results All patients underwent S-ROM prosthesis.The patients underwent transverse osteotomy of the femoral trochanter.The osteotomy length was 2.0-3.5 cm.The average follow-up time was 19 months.And no complications such as dislocation,vascular nerve injury,deep vein thrombosis and infection were observed during the follow-up.The average Harris scores improved from 42.3 preoperatively to 90.4 postoperatively at 9 months after the operation.The average lengths of preoperative limb shortening and postoperative limb shortening were 6.4 cm and 4.3 cm respectively.The X-ray films showed no dislocation of acetabulum and femoral prosthesis.Bone healing was achieved at 6 months after osteotomy.Conclusion This method could be a good choice for Crowe Ⅳ developmental dysplasia.The short-term efficacy is satisfactory.

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.

Objective To investigate CT features of primary ileocecum lymphoma (PIL),to improve the ability of CT diagnosis for the disease.Methods CT data of 12 patients with PIL confirmed by surgery and pathology were analyzed retrospectively.All of the patients underwent plain CT, and 8 cases of them also underwent enhanced CT.Results Among the 12 cases of PIL, there were mass type in 2 and diffused thickness type in 10.The length of the intestinal lesions ranged from 7.8 to 18.5 cm (mean 10.2 cm).Lumen was irregular or aneurysmal dilation in 9, and obvious stenosis in 3.Intestinal wall was soft in 10,and rigid in 2.Plain CT showed that the thickened intestinal wall was soft tissue density.Among the 8 cases performed enhanced CT,6 were approximately homogeneous enhancement, and 2 had small necrosis area without enhancement.Maximum intensity projection(MIP) displayed the lesion had blood supply from the branches of the superior mesenteric artery.Enlarged lymph nodes were detected around the lesions, in root of the mesentery, and in the retroperitoneum in 9.1 case was accompanied with intestinal obstruction,1 case was accompanied with intestinal perforation.Conclusion If CT examination found a homogeneous soft tissue mass in ileocecum with long extent, lumen dilation, soft intestinal wall,mild-to-moderate delayed homogeneous enhancement, PIL should be considered.

BACKGROUND:It is reported that bone marrow mesenchymal stem cell(BMSC)transplantation might be a promising treatment for liver fibrosis.But the mechanism is still unclear.OBJECTIVE:To observe the hepatic stellate cells apoptosis induced by BMSC transplantation,and to study the mechanism of BMSC in treating hepatic fibrosis in vivo.METHODS:CCl_4 subcutaneous injection was performed to induce rat liver fibrosis.After 8 weeks of CCU injection,20 rats which underwent successful model establishment were randomly divided into experimental group and control group,10 in each group.The experimental group received MSC transplantation via tail vein injection,and the control group were given DMEM instead.The rats were killed and the livers were harvested at three time point,the day of MSC transplantation,3 days after transplantation,and 7 days after transplantation.The hydroxyproline content was detected by HE and Masson staining,and the expression changes of α-smooth muscle actin(α-SMA)proteins were determined using immunohistochemistry.The apoptosis of hepatic stellate cells were determined by α-SMA and TUNEL(terminal dUTP nick-end labeling)dual-staining.RESULTS AND CONCLUSION:After 8 weeks of CCU injection,the hydroxyproline content increased and histology indicated progress of liver fibrosis.At 7 days after MSC transplantation,the hydroxyproline in the liver was decreased,and the liver fibrosis was alleviated in the experimental group but aggravated in the control group.Immunohistochemistry indicated that α-SMA positive cells were increased at 8 weeks after CCU injection.At day 7 after transplantation,α-SMA positive cells in the experimental group were significantly less than control group(P ＜ 0.05).At 3 days after transplantation,the hepatic stellate cells apoptosis in the experimental group was significantly aggravated compared with control group(P ＜ 0.05).This suggested that MSC transplant was an effective treatment for liver fibrosis.MSC inducing hepatic stellate cells apoptosis may be one of the mechanisms.

Objective To explore the CT and MRI features of chordoma and analysis misdiagnosis.Methods The CT and MRI imaging data were analyzed retrospectively in 1 8 patients with chordoma.The imaging findings of the preoperative misdiagnosed lesions were analyzed and summarized.Results 1 2 cases were diagnosed correctly preoperatively,6 cases were misdiagnosed.Chordoma was located in the skull base in 9 cases,in the sacrum in 8 cases,and in cervical vertebrae in 1 case.CT and MRI showed oval or round shape lesions in 12,and irregular shape in 6.14 cases of them displayed clear boundary,4 cases displayed unclear boundary.CT showed soluble osseous bone destruction and uneven isodensity or slightly low density mass.Spot or lamellar shaped calcifications or residual substances of bone were found around or inside of the lesions in 9 cases.MRI showed equal or low signal intensity on T1 WI and high signal intensely on T2 WI.After the CT and MRI contrast enhancement,mass showed mild-to-moderate heterogeneity enhancement. Conclusion Chordoma has certain characteristics on CT and MRI imaging.The combination use of CT and MRI scans has an important value in localization quantitative and qualitative diagnosis of chordoma.
