Objective Retinoic acid receptor(RAR?) selective antagonist,Ro41-5253(Ro) was used in the counteract test,to confirm the role of RAR? in enhancement of IgM synthesis in cord blood lymphocytes(CBLs) by retinoic acid(RA).Methods CBLs were cultured in vitro and stimulated with or without RAR? agonist RA and(or) antagonist Ro.The cells were harvested at 24 hours and 48 hours of culture time to measure the levels of gene expression of RARa,IL-4 and IL-6.ELISA was used to measure the concentration of IgM in the supernatant of 5 days culture.Results Ro could inhibit the promotion of RA on IgM synthesis in CBLs.RA could up-(regulate) RAR? gene expression,which could be restrained by Ro.Ro also could counteract the up-regulation of RA on IL-4 and IL-6 gene expression.Conclusion The effect of RA on IgM synthesis in CBLs is modulated by RAR?.

Objective To study the clinical effect of cervical loop electrosurgical excision procedure (LEEP) in diagnosis and treatment of cervical diseases (including cervical intraepithelial neoplasia of different grade, cervical erosion of moderate and severe degree, cervical with human papillomavims (HPV) infection and cervi-cal polyp) . Method The data of 136 cases with cervical disease treated by LEEP were analyzed retrospectively. Re-sult The postoperative diagnosis were upgraded in 18 cases (13.2%) ,and downgraded in 38cases (27.9 %) . The preoperative diagnosis of 80 cases (58.8 %) were in accordance with the postoperative ones. The difference was sig-nificant(P<0.05). The mean operative time was 11minutes, the mean bleeding volume was 15 ml. Postoperative bleeding of LEEP occurred in 2.2 % (3/136) patients. Postoperative cervical conglutination of LEEP occurred in 1. 5 % (2/136) patients. The cure rate of CIN was 96 % after LEEP. The residual CIN occurred in 4 patient (4 %). Recurrence CIN occurred in 2 patient (2 %). At 12th months after LEEP,the negative rate of HPV detection was 86. 7% and the persistent positive rate was 13.3%. The HPV clearance rate was increased gradually after LEEP. Conclu-sion LEEP was safe and effective for the treatment of the cervical disease and was a kind of good method to clear HPV infection in cervical.

Objective To investigate the distribution characteristics of motor endplates in musculuslevatorani of dif-ferent gestational ages. Methods 20~24 weeks female fetuses were categorized as Group A, and 24~28 weeks female fetuses as group B. Karnovsky-Roots iron cyanide copper staining ( hematoxylin) was used to study the aver-age weight, the morphology, distribution and changes in number of motor end plate. Results The motor endplates morphology and distribution of consistent oval of 20 ~28 weeks female fetuses showed a curve distribution in the musculuslevatorani fibers foreign 1/3 . The weight and numbers of motor endplates in Group A were less than those of group B. Conclusion 20 ~28 weeks female fetuses' musculuslevatorani are visible on the motor end plates, and no significant difference is found in morphology and distribution of the curve along the muscle fibers. The num-ber of motor endplates increases with the increase of anal muscle weight mentioned.

Objective To investigate the mechanisms of enophthalmos and deformities of orbital walls in patients with orbital blowout fracture and to evaluate the reconstructive surgical methods. Methods The features of orbital deformities, the change of orbital volume and the mechanisms of enophthalmos were measured and analyzed by means of 3-D CT technique and 3-D diagnostic computer-assisted system. The reconstructive operations were employed on these 11 cases with orbital blowout fractures to correct deformities and restore orbital volume by applying autogenous bone grafts or hydroxyapatite bone substitutes. Results There were no serious complications such as infection of bone graft, exposure of hydroxypatite implant in all 11 cases, 10 cases got satisfactory appearance of eyelids and orbit, of which thediplopia and enophthalmos were corrected with protrution of eyeball restoring normally. 1 case remained diplopia after surgical correction. Conclusions The enophthalmos is mainly caused by orbital volume enlarging and orbital content herniating into paranasal sinuses. Implanting autogenous grafts and hydroxyapatite substitutes to restore orbital volume are proved to be effective.

Fracture healing has long been a major concern for orthopedists.Currently,about 10% of fracture patients still have poor fracture healing or bone nonunion.In recent years,research has found that nerve growth factor(NGF)can promote fracture healing.This article reviews the mechanism and research progress of NGF in promoting fracture healing.NGF can promote vascular regeneration and nerve growth at callus and plays an important role in the proliferation and migration of bone cells.New animal experiments and clinical trials have confirmed the role of NGF in promoting fracture healing and further revealed its possible mechanism of action.Further research on NGF can provide new ideas for promoting fracture healing,especially for treating nonunion.

Objective To compare the clinical data of patients with chronic hepatitis B virus (HBV) carriers and chronic hepatitis B so that to provide pathological evidence for management of chronic HBV carriers with different alanine aminotransferase (ALT) levels.MethodsLiver biopsies were performed in totally of 292 cases of chronic HBV infection.The subjects were divided into HBV carrier group (G0-G1 and S0-S1) and hepatitis group (G＞ 1 and/or S＞ 1) according to the pathological diagnosis. The relationships between different age subgroups, different ALT level subgroups and pathological diagnosis were analyzed. Meanwhile,other clinical,biochemical,and iconographic indexes which were possibly related to the pathology diagnosis were compared. The multivariate analysis was done by Logistic regression equation (withdrawal method, maximum likelihood method) to definite the independent influencing factors of pathologically diagnosed with chronic HBV carrier.ResultsAmong the 292 patients,140 (47.9％) were pathologically diagnosed with chronic HBV carries and 152 (52.1％)were chronic hepatitis B. There were statistical differences between ≤35 years group and 36-40 years,＞40 years group (x2 =3.936 and 8.534,respectively; P =0.047 and 0.003,respectively). There were statistical difference among patients with ALT＜0.5×upper limit normal (ULN),(0.5-1.0) ×ULN,(1.1-1.5) ×ULN,(1.6-2.0) ×ULN and ＞2.0 × ULN (x2 =55.314,P＜0.01),while there was no significant difference between (1.1-1.5) × ULN and ＞2.0 × ULN (x2 =3.810,P=0.051). Multivariate analysis indicated that course of disease,alcohol consumption,ALT,HBV DNA level and the surface of liver (smooth or not smooth)detected by ultrasonography were independent influencing factors of pathological diagnosis of chronic HBV carriers (OR =0.995,0.224,0.516,1.308 and 0.270,respectively; P=0.005,0.007,0.000,0.025 and 0.001,respectively).ConclusionLiver biopsy is much meaningful in patients with age ＞35 years old and ALT (1-2)× ULN.

The species of bromine and iodine in aerosol samples were extracted using ultra-pure water-ultrasonic method with different time in-length and pressurizing decomposition with dilute ammonia, respectively. The efficiency of extraction and the stability of bromine and iodine species were compared under different extraction) conditions. Results showed that(1) the efficiency of extraction using pressurizing decomposition, which might destroy some unknown form of organic iodine, was relatively higher than the one by ultrasonic method;(2) I~- was unstable in added standard cellular blank filter during ultrasonic assisted extraction for long time;(3) The optimum condition was ultra-pure water-ultrasonic assisted extraction for 5 min. Moreover), the suitability of glass microfiber filter(GF) and cellular filter(CF) during extraction for bromine and iodine) species in aerosol was also compared, which indicated that GF is favorable for species analysis than CF under different kinds of extraction conditions. Based upon the extraction results, HPLC-ICP-MS approach was developed to analyze bromine and iodine) species in atmospheric aerosol. The total iodine, bromine and species in the aerosol samples collected in Hefei were then determined accordingly. The levels of total bromine and iodine) in Hefei aerosols were 883 and 231 pmol/m~3, respectively. Br~- was found to be dominant species with 68%, while BrO_3~- was undetectable. 70% of total iodine occurred as unidentified forms including soluble organic) iodine and insoluble iodine.
