Objective To analyse the cause,therapeutic modalities and prognosis of late recurrent retinal detachment after scleral buckling.Methods A total of 657 patients(657 eyes) underwent scleral buckling,and the clinical data of 16 patients(16 eyes) with recurrent retinal detachment 6 months after the procedure were retrospectively analysed. ResultsLate recurrent retinal detachment occurred in 6 to 45 months after primary surgery,(23.87?18.46)months in average,in 2.44% of all the patients.Among the 16 patients with recurrent retinal detachment,11 experienced new retinal breaks,and old breaks reopened in the other 5.Proliferative vitreoretinopathy(PVR) grade B was found in 4 patients,grade C in 10,and grade D in 2.Fifteen patients were reoperated,among whom 4 received scleral buckling,and the other 11 vitreoretinal surgery.After reoperation,the retina was reattached in 13 cases.The patients were followed up for 4 to 16 months,and no new recurrence was observed. Conclusion Late recurrent retinal detachment after scleral buckling is rare and PVR seems to be an important factor.Reoperation based on the vitreoretinal condition can yield better prognosis.

ObjectiveTo investigate the clinical features of patients with primary biliary cirrhosis (PBC) in China. MethodsThe reported articles about clinical analysis of patients with PBC in China were searched. The quality of included studies was critically evaluated. Meta-analysis was performed using RevMan 4.2 software about controlled trials. Results① Ninety-one literatures including 2315 patients wuth PBC were included. ②The common symptoms in PBC were fatigue (54.54％). AMA was found in 74.1％～100％ of patients with PBC, as well as the prevalence rate of anti-M2 range from 45％ to 83％. ANA antibodies present in 20％～83.78％ of patients, the most common antinuclear patterns were nuclear-envelope(38.65％).Increased levels of IgM [(2.8±0.7)～(7.3±5.1) g/L], IgG [(16.5±4.9)～(20.5±5.9) g/L] were found in these patients, and the most common liver histologic classification was type Ⅱ (36.6％). Sjogren's syndrome occured significantly more frequently in PBC (1.96％～34.61％). To the end of follow-up period (five months to nintysix months ), 3.80％ of patients were dead. ③ Meta-analysis performed in several case control studies, showed no significant differences was found in liver tests including of alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotrans ferase (AST), total bilirubin (TBil), or gamma-glutamyltransferase (GGT), IgG levels between AMA positive groups and AMA negative groups. However, lower levels of IgM presented in the latter. While it also showed that levels of ALP decreased after ursodeoxycholic acid (UDCA)therapy. The levels of TBil were lower in the elderly than in younger group, but the mortality ratio for liver diseases was higher in the former. ConclusionThe clinical characteristics of the present series in China are mostly similar to those reported in other countries. Because of the low quality and the small number of included studies, larger sample-size, randomized, double-blinded controlled trials are needed.

Objective:To investigate the regulatory effect of dissociative intracytoplasmic domain of leukemia inhibitory factor receptor ? (LIFR?) subunit on the growth of HL-60 cells and the related signal transduction mechanism. Methods: The constructed recombinant plasmids pcDNA3.0-190CT2+3 and cDNA3.0-190CT3 were identified and transfected into HL-60 cells with liposome FuGene-6. Then the cells were cultured in a medium containing G-418 and the positive clones were selected. Immunohistochemical method and Western blotting were used to detect the expression of the target protein in HL-60 cells and the growth curve of the cells was plotted. The expression of proliferating cell nuclear antigen (PCNA) and the phosphorylation levels of signal transducer and activator of transcription 3 (Stat3) were assayed by Western blotting. Results: Western blotting detected the band of target protein and the cell line stably expressing the target protein was obtained. Compared with that of the wild type group, the cell sizes in 190CT2+3 and 190CT3 group were enlarged. The ratio of leaf cell number to the total cell number increased and the cell proliferation was slowed down. We also found that the expression of PCNA was decreased and the phosphorylation level of STAT3 was increased. Conclusion: The dissociative intracytoplasmic domain of LIFR? subunit can accelerate the differentiation of HL-60 cells, inhibit the proliferation of HL-60 cells, and activate signal molecule STAT3.

Objective This study was designed to examine the expression of VEGF and its correlation with clinicopathological factors of cervical carcinoma. Methods mmunohistochemistry S-P method was used to detect the expression of VEGF in 10 cases of nomal cevical epithelium( NCE), 18 cases of cervical intraepithelial neoplasm (CIN) and 77 cases of early invasive carcinoma of cervix (ICC). Results The positive rate of VEGF protein in NCE,CIN,ICC was 10% (1/10) ,44.4% (8/18) ,74. 0% (57/77), respectively. The defference was significant (P ＜0. 05). Expresson of VEGF was not related with tumor stage, histologic types and stroma infiltration, but related with cell differentiation and intravascular involvement、lymph node metastasis. Conclusion VEGF protein had a positive correlation with cell differentiation and intravascular involvement 、 lymph node metastasis. the expression of VEGF gene result in the occurrence and development of cervical carcinoma by inducing the angiogenesis.

Objective To explore the secretion of chemokine regulated upon activation normal T cell expressed and secreted(RANTES)influenced by the complex microenvironment in the peritoneal cavity of women with endometriosis and investigate chemotaxis of RANTES on the peritoneal monocytes.Methods The contact and non-contact co-culture systems including three target cells of ectopic tissue were established.The three target cells were endometrial stromal cells(ESC),human peritoneal mesothelial cells(HPMC)and monocytes.After collection of the supernatant of co-culture systems,the levels of RANTES were detected by enzyme linked immunosorbent assay(EUSA).Migration of U937 cell,a monocyte line,was detected by chemotaxis assay.Results ESC,HPMC,and U937 cultured alone secreted slight RANTES,(5.0±0.5),(4.0±0.3),and (254±40)ng/L. Compared with the culture of the target cell alone,the levels of RANTES in each co-culture system increased significantly,with the highest level in the contact culture system of E-H-U(2250±96)ng/L. RANTES secretion of non-contact co-culture of three cells were higher than contact co-culture of two cells(P＜0.01):U/E-H(912±93) vs E-H(50±40)ng/L,H/E-U(1201±93) vs E-U(243±192)ng/L,and E/H-U(1519±96) vs H-U(1251±73)ng/L. ESC,HPMC,and ESC-HPMC co-culture improved significantly migration of U937 cells [ number of cell migration respectively(6.0±0.3),(6.2±0.3),(10.0±0.3)×103,P＜0.01],which could be inhibited efficiently by anti-RANTES neutralizing antibody.Condusion The target cells in the peritoneal cavity of patients with endometriosis promote the secretion of RANTES in autocrine and paracrine manners and migration of monocytes.

Objective To assess the feasibility, safety and curative effect of permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy for the treatment of non-small cell lung carcinoma (NSCLC) in aged patients. Methods CT-guided permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy was performed in 46 patients with NSCLC, of whom 26 received primary treatment and 20 underwent renewed treatment. During the procedure, ~(125)I seeds were embedded into the tumor in all the patients. Three to five days after the implantation, GP scheme chemotherapy started. GEM (1 000 mg/m~2) was given (intravenously dripping for 30 min.) on the 1st, 8th and 15th day; DDP (30 mg/m~2) was employed on the 1st, 2nd and 3rd day, and recombinant human endostatin (Endostar, 7.5 mg/m~2) was administered (intravenously dripping for 3-4 hours) from the 1st to the 14th day. Every 28 days completed one treatment course. Two months after ~(125)I seed implantation, at this time the patient had received two courses of treatment, the short-term effect and the toxic side-effect were evaluated. Results Two months after the ~(125)I particles were embedded in the tumor, all the 46 cases were able to be evaluate for the curative effect. Of 46 patients, complete relief (CR) was seen in 12, partial relief (PR) in 24, stable (SD) in 6 and progression (PD) in 4, with an effective rate of 78.26%. Of 26 patients in the primary treatment group, CR was obtained in 7, PR in 15, SD in 3 and PD in 1, with an effective rate of 84.6%. Of 20 patients in the renewed treatment group, CR was seen in 5, PR in 9, SD in 3 and PD in 3, with an effective rate of 70.0%. Conclusion Permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy is an effective, safe and feasible treatment for NSCLC in aged patients.

Objective To evaluate the association of serum uric acid and the incidence and prognosis of kidney diseases systematically, so as to provide reference for the treatment and prevention of kidney diseases. Methods Literatures related to the associations between serum uric acid and incidence and prognosis of kidney diseases were selected from the Chinese Biomedical Literature Database ( CBM) (January 1982 to March 2010), EMBASE (January 1966 to March 2010) and Medline (January 1950 to March 2010) for cohort studies. Two researchers independently screened the studies, assessed the risk of bias of included studies using the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies and extracted data. Stata 10. 0 was used to calculate the pooled relative risk. Results Twenty-one eligible cohort studies were selected, of which 11 on incidence of kidney diseases (n =276 801 ) , and 10 on the prognosis of kidney diseases ( n = 3004). Meta analysis was performed based on data influencing incidence and prognosis factors of kidney diseases except for serum uric acid. The results showed, (1) uric acid and incidence of kidney diseases: hyperuricemia could increase the risk of kidney diseases ( RR = 1. 49, 95% CI 1. 27-1. 75) ; (2) uric acid and prognosis of patients with kidney diseases:hyperuricemia could deteriorate the kidney function (RR = 1. 35, 95%CI 1. 12-1.63) and increase the risk of mortality (RR = 1.67, 95% CI 1.29-2.16). Conclusion Uric acid is an independent risk factor for incidence of kidney diseases and poor prognosis of patients with kidney diseases. Further high quality clinical trials with long-term follow up should be conducted to determine whether lowering uric acid levels would be of clinical benefit in the prevention and treatment of kidney diseases, so as to provide direct evidence for clarifying correlation between uric acid and kidney diseases and the prevention and treatment for patients with high uric acid.
