Effect of pre-shaped titanium mesh implantation on the prognosis of patients with orbital fractures / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To study the effectiveness and safety of 3D printing pre-shaped titanium mesh in the repair of orbital fracture compared with the conventional titanium mesh. <p>METHODS: The clinical data of 72 eyes of 72 patients who received surgery for orbital fracture from June 2015 to March 2016 in our department were retrospectively analyzed.All patients were divided into two groups, including pre-shaped titanium mesh implantation group(observation group), 40 cases, conventional titanium mesh implantation group(control group), 32 cases. The control group was treated by physicians according to the experience of manual bending and shaping titanium mesh implantation ipsilateral orbital pad,when the observation group by the physicians directly in the pre-shaped titanium mesh of 3D printing. The eyeball exophthalmos, eye movement and diplopia were evaluated in the next 1, 3 and 6mo after the operation, and we compared the differences between the two methods at different time points and the differences of the indexes between the two materials at the same time point. <p>RESULTS: The cure rate of the observation group and the control group about eyeball exophthalmos values was 84% and 59%, the difference of the two groups was statistically significant(<i>P</i><0.05). The cure rates of diplopia of the two groups were 80% and 70% without significant difference(<i>P</i>>0.05). The cure rate of limited ocular movement of observation group was 73%, that of control group was 66%, there was no statistical significance(P>0.05). During the follow-up period, there was no infection in the two groups, no titanium mesh shift, extrusion, deformation and rejection or other complications. <p>CONCLUSION: Pre-shaped titanium mesh shaping orbital implantation with no need for shaping the mesh in the operation, can shorten the operation time, make accurate reconstruction of orbital wall, reduce complications and improve the curative effect.

Clinical efficacy and safety of sequential treatment with alprostadil and beraprost sodium for chronic renal failure induced by chronic glomerulonephritis / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy and safety of sequential treatment with alprostadil and beraprost sodium for chronic renal failure caused by chronic glomerulonephritis.</p><p><b>METHODS</b>Sixty-three patients with chronic renal failure due to chronic glomerulonephritis, after receiving a 2-week-long conventional treatment, were randomly divided into alprostadil group (n=20, with alprostadil injection at 10 µg/d for 2 weeks), sequential treatment group (n=21, with alprostadil injection at 10 µg/d for 2 weeks and oral beraprost sodium at 20 µg three times a day for 12 weeks), and strengthened sequential treatment group (n=22, with alprostadil injection at 20 µg/d for 2 weeks and a double dose of oral beraprost sodium for 12 weeks). Urinary albumin excretion rate (UAER), cystatin C (Cys C), blood urea nitrogen, creatinine, fibrinogen, D-dimer, prothrombin time (PT), and platelets were tested before and after the treatment, and the changes in urinary albumin discharge rate, serum creatinine, and glomerular filtration rate were determined.</p><p><b>RESULTS</b>The patients in strengthened sequential treatment group showed a significantly decreased change rate of urinary albumin discharge rate (P<0.01) than those in the other two groups. In the two sequential treatment groups, especially the strengthened treatment group, the change rate of glomerular filtration rate increased significantly compared with that in alprostadil group (P<0.01). Strengthened sequential treatment resulted also in significantly decreased increment of serum creatinine compared that in the other 2 groups (P<0.01). After 14 weeks of treatment, fibrinogen and D-dimer were decreased in all the 3 groups (P<0.05) to a comparable level between the 3 groups (P>0.05), and prothrombin time (PT) or platelet showed no significant changes (P>0.05).</p><p><b>CONCLUSION</b>Sequential treatment with alprostadil and beraprost sodium can improve the glomerular filtration rate and decrease urine albumin excretion rate, serum creatinine increase rate, and lower blood fibrinogen and D-dimer levels, thus delaying the progression of chronic renal failure caused by chronic glomerulonephritis. This therapy shows a dose-related effect with good clinical safety.</p>

A preliminary approach of covering corrugator with rectangle periosteous flap in rhytidectomy / 中华整形外科杂志

<p><b>OBJECTIVE</b>To evaluate the aesthetic outcome after application of rectangle periosteous flap to cover corrugator.</p><p><b>METHODS</b>On the basis of regular rhytidectomy, a inter-eyebrow periosteous flap is applied to cover the fascia flap of corrugator by means of turnover. This manipulation helps to separate the skin from the muscle and prevent the re-adherence between the skin and muscle.</p><p><b>RESULTS</b>The approach was applied on 15 cases. The follow-up ranged from 6 months to 1 year. The results were satisfactory.</p><p><b>CONCLUSIONS</b>The method is effective in elimination of inter-eyebrow crease.</p>
