AIM: To observe the clinical effects of moisturizing eye decoction combined with artificial tears in the treatment of ophthalmoxerosis.METHODS: A randomized controlled clinical research method was employed.One hundred-sixty patients diagnosed with ophthalmoxerosis were equally divided into a treatment group and a control group.In the treatment group,patients were given one dose per day of the moisturizing eye decoction as well as artificial tear drops three times a day.The patients in the control group were treated with artificial tears drops three times a day.The course of treatment was 3mo.Dry-eye symptoms,tear break-up time(BUT) by the slit lamp,the time of tear secretion (Schirmers Ⅰ test),corneal fluorescein staining (FL),and curative effects were observed before treatment as well as in the first and third months after treatment.RESULTS: There were no significant differences between the two groups in terms of BUT,SⅠt,and FL before treatment (P>0.05).After treatment in the first and the third months,the BUT,SⅠt,FL,and curative effects were significantly different between the two groups (P<0.05).CONCLUSION: Moisturizing eye decoction combined with artificial tears in the treatment of ophthalmoxerosis can improve efficacy.

Objective To study clinical application and complication of heavy silicon oil (Densiron68) in the treatment of traumat- ic proliferative vitreoretinopathy.Design Non-comparatives,retrospective case series.Participants Twenty patients with proliferative vitreoretinopathy resulting from ocular trauma were recruited,whose retinal detachment arising from inferior or posterior retinal breaks. Methods Heavy silicon oil was applied to patients during vitrectomy.Silicone oil or gas was applied to patients with redetachment after heavy silicon oil was removed.Main Outcome Measures The rate of retinal attachment,vision,intraocular pressure,inflammatory re- action of anterior segment and silicone oil emulsification period.Results The rate of retinal attachment with one operation using heavy silicon oil was 50%(10/20 eyes)and 15%(3/20 eyes)with further surgery.The average follow-up time was 3.90?1.41 months.At the end of the follow-up,all tamponade agents were removed in 50% patients.Patients' logMAR vision after the surgery was 2.19?0.86,which was better than before the surgery (2.63?1.00) (P=0.037).There was little evidence of high intraocular pressure,excessive inflammatory reaction of anterior segment and cornea endothelial cell damage,but cataract became more serious without exception.Emulsification rate was 100% and the average emulsification period was 2.18?0.87 months.Conclusions Heavy silicon oil tamponade in vitreoretinal surgery for traumatic proliferative vitreoretinopathy has good efficacy and relatively few complications.However,its emulsification period is relatively short,which may constraint its application to a certain extent.

AIM: To explore the effect of different corneal incision size on change in tear function after phacoemulsification cataract surgery in type 2 diabetics.
●METHODS:One hundred and fifty patients with type 2 diabetes (150 eyes) from Jan. 2015 to Oct. 2015 in our hospital were enrolled. The patients were randomly divided into two groups. Seventy-five patients (75 eyes) in group A: coaxial 2. 2mm micro - incision phacoemulsification cataract extraction and intraocular lens (lOL) implantation; seventy-five patients (75 eyes) in group B:the conventional coaxial 3. 0mm small incision phacoemulsification cataract extraction and lOL implantation. The difference of demographic characteristics between two groups were insignificant. The ocular surface disease index ( OSDl ) , corneal sensation, break up time (BUT) and Schirmer′sltest(Slt) were examined preoperatively and 1wk, 1, 3 and 6mo postoperatively.
●RESULTS:At 1wk, 1 and 3mo postoperatively, the OSDl score in two groups increased and the OSDl score of group B was significantly higher than those of group A and the differences were statistically significant ( all P<0. 05 ) . The corneal sensation in two groups decreased after operations and the corneal sensation of group B was significantly lower than those of group A and the differences were statistically significant (all P<0. 05). The Slt in two groups decreased after operations and the Slt of group B was significantly lower than those of group A and the differences were statistically significant (all P<0. 05). At 1wk and 1mo postoperatively, the BUT in two groups decreased after operations and the BUT of group B was significantly lower than those of group A and the differences were statistically significant (all P<0. 05). At 6mo postoperatively, no significant change was found in the OSDl score, corneal sensation, BUT and S l t of group A compared with preoperatively (all P>0. 05). At 6mo postoperatively, the differences of OSDl score and corneal sensation in group B were statistically significant compared with preoperatively ( all P< 0. 05 ) while no significant change was found in the BUT and S l t of group B (all P>0. 05).
●CONCLUSION:Phacoemulsification surgery with 2. 2mm corneal micro-incision has less effect on change in tear function comparing to the 3. 0 mm incision control, which can be applied particularly in patients with type 2 diabetes.

ObjectiveTo explore the feasibility and efficacy of hyperbaric oxygen (HBO) therapy combined with mild hypothermi on severe craniocerebral injury (SCI).MethodsAll 80 SCI patients were randomly divided into therapeutic group (52 cases) and control group (28 cases). All patients received general synthesis treatment; while the hyperbaric oxygen combined with mild hypothermia treatment was added to the therapeutic group. Changes of Vm, Vs and PI of middle cerebral artery (MCA) in systolic stage were detected by transcranial-Doppler (TCD) before and after treatment. The plasma level of endothelin (ET) was also tested and prognosis of patients was analyzed.ResultsVm, Vs and PI of MCA in systolic stage improved obviously and ET reduced greatly in therapeutic group compared with those in the control group (P<0.01), and prognosis was also superior to control group.ConclusionHyperbaric oxygen combined with mild hypothermia can improve the consciousness state and prognosis of SCI patients as a result of the relaxation of the cerebral vascular spasm and the reduction of ET, which may contribute to the abatement of the cerebral ischemia and hypoxia.

Objective To evaluate the effects of different concentrations of hydroxyethyl starch (HES) 130/0.4 applied for different time periods on injury to human renal tubular epithelial cells.Methods Human renal kidney epithelial cells HK-2 at the logarithmic growth phase were seeded in 96-well plates at a density of 1 × 105 cells/ml (0.1 ml/well),in culture flasks (5 ml/flask) or in cluture dishes (5 ml/dish).HK-2 cells were randomly divided into 4 groups (n=49 each) using a random number table:control group (group C) and 0.3％,1.5％ and 3.0％ HES 130/0.4 groups (H1,H2 and H3 groups).In H1,H2 and H3 groups,HK-2 cells were incubated with 0.3％,1.5％ and 3.0％ HES 130/0.4,respectively.The equal volume of PBS was added to the culture medium in group C.At day 1,3,5 and 7 of incubation,the cell viability was measured.At day 3,5 and 7 of incubation,cell apoptosis was detected,and apoptosis rate was calculated.On day 7 of incubation,the cells were stained with toluidine blue for examination of intracellular HES deposition (under light microscope) and pathological changes (with transmission electron microscope).Results Compared with group C,the cell viability was significantly decreased on day 5 and 7 of incubation,and apoptosis rate was increased on day 3,5 and 7 of incubation in group H3,and no significant difference was detected in the parameters mentioned above in H1 and H2 groups.Microscopic examination showed that intracellular HES deposition was observed in H2 and H3 groups,and pathological changes were obvious,and apoptotic cells were also found in H3 group.Conclusion Application of high-concentration HES 130/0.4 for a long period can lead to injury to human renal tubular epithelial cells,however,application of high-or low-concentration HES 130/0.4 for a short period produces no influence on the cells.

Objective To investigate the diagnostic value of transrectal ultrasonography (TRUS)for female traumatic urethral stricture.Methods Fifteen female patients with traumatic urethral stricture were examined by using TRUS and urethrography and the examination results were compared with op-eration findings.Results The ultrasonography results of all patients were in consistency with their operation findings,while the urethrography results of six patients were different from their operation findings.Conclusion TRUS is of great value in the diagnosis of female traumatic urethral stricture.
