·AIM: To evaluate the efficacy and safety of intravitreal triamcinolone acetonide(TA) as treatment for macular edema associated with retinal vein occlusion(RVO).·METHODS: The study group consisting 30 patients (30 eyes) with RVO combined with macular edema received intravitreal 4mg TA. Changes in best-corrected visual acuity (BCVA), intraocular pressure(IOP), examination with slit-lamp microscope, fluorescein angiography and optical coherence tomography(OCT) were observed during the follow-up. Statistical analysis was conducted with SPSS 12.0 software.·RESULTS: The visual acuity(VA) of all patients was significantly improved and the central macular thickness (CMT) was significantly relieved. There was no correlation between course, age, CMT before injection and the type of RVO. There was positive correlation between visual acuity before injection and after injection.·CONCLUSION: Intravitreal injection of TA is an easy-operated and safe therapy. After injection, macular edema can be rapidly relieved. VA at baseline is the predictor for the prognosis of VA. Some patients experience recurrence of macular edema between 3 to 6 months after injection.

OBJECTIVETo investigate the malondialdehyde (MDA) level and paraoxonase-1 (PON-1) activity in the serum and seminal plasma of infertile men with chronic viral hepatitis and their influence on the semen parameters of the patients.
METHODSWe collected serum and semen samples from 42 infertile men, 45 infertile males with chronic viral hepatitis, and 50 healthy fertile men as controls. We measured the MDA level in the serum and seminal plasma by spectrophotometry, detected the PON-1 activity by spectrophotometry, and determined the sperm DNA fragmentation index (DFI) by acridine orange fluorescence staining.
RESULTSThe MDA level was significantly higher but the PON-1 activity remarkably lower in the serum and seminal plasma of the infertile males with chronic viral hepatitis than in the healthy controls and infertile patients (P <0.01 or P <0.05). Total sperm motility and sperm survival rate were significantly lower while the sperm DFI markedly higher in the former than in the latter two groups (P <0.01 or P <0.05). No statistically significant difference was found among the three groups in sperm concentration (P >0.05). The WBC counts in the semen of the infertile and infertile with chronic viral hepatitis groups were significantly higher than that in the health controls (P <0.05). The MDA level and PON-1 activity in the seminal plasma were positively correlated with those in the serum in the infertile males with chronic viral hepatitis (r=0.57 or 0.48, P <0.01).
CONCLUSIONVirus-induced chronic active hepatitis enhances oxidative stress in the reproductive system, aggravates sperm damage, and affects sperm quality parameters.

It has been well-known that intravenously infused hematopoietic stem and progenitor cells can home to the bone marrow and reconstitute hematopoiesis. However, little is understood about the homing efficiency or percentage of infused stem and progenitor cells. In order to examine distribution pattern of infused hematopoietic cells in the organs and tissues, a direct assay system to trace transplanted cells in vivo by employing PKH-26, a red fluorescent membrane dye, to label hematopoietic cells in inbred strain of mice transplanted cells (stem cell antigen-1 positive subpopulation cell, Sca-1(+) cells) was introduced. The numbers of labeled cells was measured by means of flow cytometry and fluorescence microscopy. The early fate of infused Sca-1(+) donor bone marrow cells after intravenous administration in a allogeneic mouse model was examined. The presence of infused donor cells with the fluorescent dye PKH-26 was evaluated within 60 hours in hematopoietic organ (bone marrow and spleen) and non-hematopoietic organ (lungs and liver) of recipients. The data showed that (1) Following intravenous infusion, Sca-1(+) donor bone marrow cells were detained in lungs shortly. (2) Sca-1(+) donor bone marrow cells localized to both hematopoietic organ (bone marrow and spleen) and non-hematopoietic organ (lungs and liver) for periods of up to 60 hours following infusion, however, the number of donor hematopoietic cells localized to bone marrow was more than that localized to non-hematopoietic organ (P < 0.05). These results indicated that there were also donor early hematopoietic cells in non-hematopoietic organ of recipients at the homing phase in allo-BMT mice.

In order to explore the improvement of seeding efficiencies of infused donor hematopoietic cells to bone marrow in bone marrow transplantation, two recipient groups of syngeneic rat model which received transplanted cells labeled with PKH-26, a red fluorescent membrane dye, by aortic or intravenous administration (2 x 10(7) nucleate cells per recipient rat) respectively, were assayed; at selected times following BMT, partial recipient rat were euthanized and then measured the numbers of PKH-26 labeled cells in recipient rat marrow samples by means of flow cytometry. The results showed that the homing indices of donor hematopoietic cells in aortic group and intravenous group were (14.52 +/- 1.07)% and (10.49 +/- 0.72)% at 30 hours after BMT, respectively (P < 0.05). The results indicated that the number of donor hematopoietic cells localized to recipient bone marrow infused by aortic route is more than that infused by intravenous route.

OBJECTIVETo compare the clinical effects and safety of dynamic external fixtor combined with limited internal fixation and cross K-wires fixation for the treatment of close Pilon fractures of the proximal interphalangeal joint.
METHODSFrom June 2012 to June 2014, totally 41 patients (45 fingers) with close interphalangeal joint Pilon fracture were treated by dynamic external fixtor combined with limited internal fixation or cross K-wires fixation, and all the patients were followed up. In the dynamic external fixtor combined with limited internal fixation group (group A), there were 21 patients with 22 fingers, including 12 males and 9 females, with an average of (30.6±5.6) years old. In the cross K-wires fixation group (group B), there were 20 patients with 23 fingers, including 11 males and 9 females, with an average of (30.1±5.3) years old. Regular re-examination of X-ray was performed to evaluate the active range of joint motion, fracture healing time, infection rate and postoperative joint motion pain.
RESULTSAccording to the evaluation criteria of upper extremity function issued by the Hand Surgery Society of Chinese Medical Association, the excellent and good cases of group A was up to 19 and 13 for group B. The evaluation results has significant differences (Z=2.558, P=0.011). The excellent and good rate of group A was obviously higher than that of group B. The average bone union time of group A was (7.9±2.1) weeks, and (8.1±2.3) weeks for group B. There was no significant difference on the mean healing time (t=-0.304, P=0.762). The infection fingers of group A was 5, and 1 for group B. The difference between the results was statistically significant (χ2=3.287, P<0.05). The infection rate of group A was higher than that of group B. The postoperative joint motion pain was evaluated by VAS score, the mean score was 0.18±0.50 in group A, and 0.65±0.88 in group B. The difference between the results was statistically significant (t=-2.207, P<0.05). The postoperative joint motion pain was lower than that of group B.
CONCLUSIONDynamic external fixtor combined with limited internal fixation is a reliable and effective method to treat Pilon fractures of the proximal interphalangeal joint. It allows early postoperative functional rehabilitation and restores the joint function.

AIM: To explore the relationship of central retinal vein occlusion ( CRVO) and atherosclerosis ( AS) .
METHODS:Fifty cases of CRVO patients were chosen as the observation group in our hospital from October 2012 to October 2014, other 50 patients with AS ( non-CRVO) as control group. In the control group, 22 cases of AS mild stenosis, moderate stenosis in 24 cases, 4 cases of severe stenosis ( 3 cases implanted stent ) . According to the severity, two grade prevention primary prevention therapy, and cerebral vascular disease treating stroke, corresponding drug treatment was undergone. Two groups of patients were performed cervical carotid artery color Doppler ultrasound examination, including assessing plaque, carotid artery intima-media thickness ( IMT) , the degree of stenosis of internal carotid artery blood flow velocity and the systolic peak ( PSV ) , end diastolic blood flow velocity ( EDV) , resistance index ( RI) values for kinetic parameters etc. All the indexes of the two groups were compared with color Doppler ultrasound examination results, to evaluate the correlation between CRVO and AS.
RESULTS: In the observation group, 15 cases were detected of carotid artery with mild stenosis, 28 cases of arterial diameter reduced <50%, carotid artery moderate stenosis, arterial diameter was reduced from 50% ~69%, 6 cases of carotid artery stenosis, arterial diameter was reduced from 70% ~99%, 1 patient with ipsilateral carotid artery near occlusion. In the control group, 22 cases were of AS mild stenosis, moderate stenosis in 24 cases, 4 cases of severe stenosis ( 3 cases implanted stent ) . The eyes with CRVO increased IMT, PSV and EDV decreased, RI value increased (P<0. 05). Compared with the control group, hypertension, hyperlipidemia, hypercholesterolemia, diabetes mellitus in observation group were statistically significant difference (P<0. 05). The control group of 2a of follow-up showed no recurrence during CRVO.
CONCLUSION: CRVO and AS are highly correlated, the neck of Doppler ultrasound examination can clearly reflect the central retinal vein blood supply, the standard treatment for AS disease, can reduce the risk of CRVO, with certain clinical significance.
