Objective To investigate the risk factors and treatment of silicone oil glaucoma (SOG).Methods Ninety-five eyes of 93 patients who underwent pars plana vitrectomy and silicone oil tamponade were evaluated in this study. The lens was removed in 58 eyes in which intraocular lens (IOL) was implanted in 10 eyes, so 48 eyes were aphakic. Silicone oil tamponade time was ≤6 months in 32 eyes,and ＞6 months in 63 eyes. The follow-up time ranged from 2 to 25 months, with a mean of (9.5±5.1)months. The fundus and intraocular pressure (IOP) were evaluated at 1 week, 2 weeks and 1 month after surgery. The diagnosis of SOG was established if the one-month postoperative IOP ＞ 21 mm Hg (1 mm Hg=0.133 kPa), and primary and neovascular glaucoma were excluded. After the diagnosis of SOG, carteolol hydrochloride and brinzolamide solution were immediately applied to the eye, and intravenous mannitol infusion was performed. If the IOP still can not be controlled after 1 week of such treatment, silicone oil removal surgery will be performed. If removal of silicone oil can not control the IOP,trabeculectomy surgery will be performed. Results SOG occurred in 21 eyes (22.1%), including 5 phakic eyes (10.6% of 47 phakic eyes) and 16 aphakic eyes (33.3% of 48 aphakic eyes) , 3 eyes (9.4% of 32 eyes)with short tamponade time (≤6 months) and 18 eyes (28.6% of 63 eyes) with long tamponade time (＞6months). The average silicone oil tamponade time was (10.8±5.1) months. Emulsification of the silicone oil occurred in 17 eyes (81.0%). After silicone oil removed, IOP was controlled in 17 eyes (81.0%) within one week. Conclusions Aphakic eye and the duration of silicone oil tamponade are the risk factors of SOG.Emulsification of silicone oil is the main cause. Silicone oil removal is an effective way to treat SOG.

Objective To evaluate the effects of inflammatory cytokines,including tumor necrosisfactor TNF-α and interleukins(IL-6 and IL-8),to the expression of pigment epithelium-derived factor(PEDF)in human retinal pigment epithelium(RPE)cells.Method Cuhured primary human RPE cellswere treated with 20,2,0.2,and 0.02 ng/ml of TNF-α,IL-6 and IL-8 separately.The levels of PEDFexpression were determined by Western blot of the supernant after 6,1 2,24 and 48 hours of culture.Results PEDF secretion of RPE cells was inhibited by TNF-α,IL-6 and IL-8 in a time-and dose-dependent fashion.Compared with the controls,the expression of PEDF decreased significantly in 0.02ng/ml and 6 hours group(F=7.14,P<0.05),2.00 ng/ml and 48 hours group(F=14.05,P<0.01),and 20.00 ng/ml and 24 hours group(F=11.53,P<0.01).TNF-α was the most strength inhibitor(F=14,P<0.01).Conclusion TNF-α,IL-6,and IL-8 could suppress the expression of PEDF in thecultured human RPE cells.

OBJECTIVE:To investigate and analyze the causative factors and characteristics of drug-induced rhabdomyolysis in China,in order to reduce the incidence of rhabdomyolysis. METHODS:Search all cases of rhabdomyolysis in China Knowledge Re-source Integrated Database from Jan 1975 to Jun 2014. Sex,age,disease history,drugs administered,drug combination,clinical presentation and outcome of rhabdomyolysis were censused and analyzed. RESULTS:There were altogether 185 rhabdomyolysis cas-es reported,of which 57.8% were over 60 years old ,78.9% were induced by lipid regulators,and 55.7% were by statins;74.1%occurred within 1 month after drug administration,and 86.6% became normal within 1 month when causative drugs discontinued or with treatment;and 4.9% died. CONCLUSIONS:Eldly,complicated with multi-factors,such as multiple organ dysfunction syn-drome,irrational drug combination and over-doses,especially with lipid regulators,are important causative factors of rhabdomyoly-sis. Individualized administration of drugs and prescription as less as possible should be recommended to reduce the incidence of rhabdomyolysis.

Objective To analyze the value of dual-source computed tomography (DSCT)in the diagnosis of complex congenital heart disease(CCHD).Methods DSCT angiography and transthoracic echocardiography (TTE)were retrospectively assessed in 46 patients who were confirmed by surgery with 107 deformities.Results There were 49 intracardiac deformities and 58 extracardiac deformities.The diagnostic accuracies in detection of intracardiac malformation were 81.63%(40/49)on DSCT and 93.88%(46/49) on TTE,those in detection of extracardiac malformation were 94.83%(55/58)on DSCT and 58.62%(34/58)on TTE,and the overall accuracies of cardiovascular malformations were 88.79%(95/107)on DSCT and 74.77%(80/107)on TTE,respectively,exhibting statistical differences.The diagnostic accuracy of DSCT in combination with TTE in detection of intracardiac and extracardiac malformation was 94.39%(101/107),which was higher than DSCT or TTE with statistical differences.Conclusion The combination of TTE and DSCT is helpful to improve the diagnostic accuracy of CCHD.

Objective To investigate the setup error for nasopharyngeal carcinoma (NPC) patients with poor compliance using kV cone-beam computed tomography,and to calculate the expansion margin from the clinical target volume (CTV) to planning target volume (PTV).Methods In 45 NPC patients from 2013 to 2015,the setup error,95％ confidence interval (CI)-1 for random error,and PTV-1 value were calculated.Moreover,in 16 NPC patients with poor compliance based on five verifications (random error not within 95％ CI-1),the setup error,95％ CI-2 for random error,and PTV-2 value were calculated.For the 16 special patients,PTV-1 and PTV-1 combined with PTV-2 were used to develop the plan-1 and plan-2,respectively.The dosimetric difference between plan-1 and plan-2 was evaluated.Results Both PTV-1 and PTV-2 had the largest expansion margin in the y direction.The CTV of plan-1 could not meet the requirement of the prescription dose after the setup error was introduced.Compared with plan-1,the V95％ and D95 values for the CTV of plan-2 were increased by 6.26％ and 4.43％,respectively.The D01 value was significantly larger in plan-2 than in plan-1 (P=0.005),which,however,met the clinical requirement.Conclusions In patients with poor compliance,the dose to target volume can be effectively elevated and the normal tissue can be spared from damage when PTV-1 combined with PTV-2 is selected as expansion margin.

Objective To conduct a retrospective study about drug-induced hyperthermia (DIH) based on DIH data obtained in medical practice,and elucidate the relationship between DIH incidence and antibacterials overuse.Methods To investigate successively the medical records of inpatients from orthopaedics department in Fudan university affiliated Jinshan hospital at two different periods,and data of DIH cases were extracted to perform a comparative study.The period for 229 effective cases of group Ⅰ was from Feb.1 to Apr.30,2011,before significant improvement on antibacterials use.The period for 342 effective cases of group Ⅱ was from Jul.1 to Sep.30,2012,after the effective enforcements of regulation on antibacterials use.Inclusion criteria for DIH were:①an oral temperature ≥37.6 ℃ since postoperative day 4,②no evidence of infection,③a time relationship between fever and the administration of causative drugs:a fever occurring with drug administration and disappearing after drug cessation within 3 days,④no other causes for the fever,⑤oral temperature ≤ 37.6 ℃ until leaving hospital.Exclusion criteria for DIH were listed below:①possible pathological fever,e.g.,in cancer,②hospitalization within 3 days,③no surgery,④severe trauma,for example,visceral or central nervous system injury.Results All causative drugs were for injection.By comparison,duration of antibacterial administration is significantly shorter in group Ⅱ than in group Ⅰ (1.7 ± 1.7 vs.4.6-± 1.8days,P ＜ 0.01),and total DIH incidence and antibacterials related DIH incidence were significantly lower in group Ⅱ than in group Ⅰ (7.3％ vs.30.1％,1.5％ vs.25.3％,both P ＜0.01).Conclusion DIH incidence is related with drug type especially with antibacterials overuse,and changed with drug program.DIH was more serious for injection of antibacterials than injection of traditional Chinese medicine.Decrease of antibacterials usage is positively associated with the decreased DIH incidence.Safe medication should begin from safe usage of antibacterials.
