BACKGROUNDCurrently, all frequently used staging systems in gallbladder cancer (GBC) are based on postoperative pathological examinations. In patients undergoing curative operation, there is no effective method to predict survival preoperatively. In this study, we explored whether a combined utilization of two tumor biomarkers, namely carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen (CEA), could give a preoperative prediction of survival in resectable GBC.

METHODSSeventy-three patients who underwent radical resection for GBC were included in this study. A retrospective analysis of clinical-pathological data was conducted.

RESULTSBy multivariate analysis, CA 19-9 elevation (P < 0.05) and CEA elevation (P < 0.001) were discovered as two individual factors for postoperative survival. By a combined utilization, patients were divided into three groups: patients with elevation of CEA (group I), patients with elevation of CA 19-9 but without CEA (group II), and patients with nonelevations of either CA 19-9 or CEA (group III). The cumulative 5-year survival rates in groups I, II, and III were 0, 14.0%, and 42.8%, respectively (P < 0.05).

CONCLUSIONSBy a combined utilization of CA 19-9 and CEA, individualized prediction of survival is available in resectable GBC before operation. Extended radical operation brings the most prognostic benefits in patients with nonelevations of either CA 19-9 or CEA. However, if operation would be in a larger-scale destructive manner, careful consideration of surgical decisions should be made in patients with elevation of tumor biomarkers, especially CEA.

OBJECTIVETo examine the prognosis of preretinal hemorrhage following vitrectomy and silicone oil tamponade for severe proliferative diabetic retinopathy.

METHODSClinical data of 76 cases of proliferative diabetic retinopathy treated with vitrectomy and silicone oil infusion tamponade in Sir Run Run Shaw Hospital from October 2006 to September 2013 were retrospectively reviewed. Intraoperative bleeding,postoperative preretinal bleeding,blood reabsorption time, and preretinal fibrosis were assessed.

RESULTSAll preretinal hemorrhage developed within 1 week after surgery, blood was distributed in thin and scattered patterns (32 cases), thick and localized patterns (25 cases) or thick and scattered patterns (19 cases). The preretinal hemorrhage was ceased in 1 day after operation in 35 cases, in 2 days after operation in 18 cases, in two weeks after operation in 23 case. Recurrent hemorrhage occurred within 1 week after operation in 15 cases. Thin blood was largely reabsorbed in about two weeks, and thick blood was largely reabsorbed in about five weeks. Fibrosis tissue was resulted in 15 cases(34.1%) with thick blood.

CONCLUSIONMost of preretinal hemorrhage occurs within 1 week after surgery and is reabsorpted with 5 weeks in patients with proliferative diabetic retinopathy undergoing vitrectomy and silicone oil tamponade. The major complication of preretinal bleeding is the formation of preretinal fibrosis.

OBJECTIVE: To investigate the effects of corneal thickness distribution and apex position on postoperative refractive status after full-bed deep anterior lamellar keratoplasty (FBDALK). METHODS: This is a retrospective analysis of patients who were diagnosed with advanced keratoconus between 2011 and 2014 in our hospital. The base of the cone in all patients did not exceed the central cornea at a 6-mm range. The FBDALK was performed by a same surgeon. All patients had a complete corneal suture removal and the follow-up records were intact. Patients who had graft-bed misalignment or who were complicated with a cataract or glaucoma were excluded. Uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), and Pentacam examination data were recorded at two years postoperatively. The recorded data included the superior-inferior (S-I) and nasal-temporal (N-T) corneal thickness differences in 2, 4, 6, and 8 mm diameter concentric circles with the corneal apex as the center (S-I_{2 mm}, S-I_{4 mm}, S-I_{6 mm}, S-I_{8 mm}, N-T_{2 mm}, N-T_{4 mm}, N-T_{6 mm}, and N-T_{8 mm}), the linear, X-axis, and Y-axis distance between the corneal pupillary center and the cornea apex, total corneal astigmatism at a zone of 3 mm diameter from the corneal apex (TA_{3 mm}), the astigmatic vector values J₀ and J₄₅, and the corneal total higher-order aberration for 3 and 6 mm pupil diameters (HOA_{3 mm} and HOA_{6 mm}). Statistical analysis was performed by SPSS 15.0. RESULTS: A total of 47 eyes of 46 patients met the criteria and were included in this study. The mean follow-up time was (28±7) months. The mean UCVA was 0.45±0.23 (logMAR) (MAR: minimum angle of resolution) and the mean BSCVA was 0.19±0.15 (logMAR), which were all significantly positively correlated with postoperative TA_{3 mm} and HOA_{3 mm}. The mean S-I corneal thickness differences were (44.62±37.74) μm, and the mean N-T was (38.57±32.29) μm. S-I_{2 mm} was significantly positively correlated with J₀ (r=0.31), J₄₅ (r=0.42), HOA_{3 mm} (r=0.37), and HOA_{6 mm} (r=0.48). S-I_{4 mm} and S-I_{8 mm} were significantly positively correlated with HOA_{3 mm} (r=0.30, r=0.40) and HOA_{6 mm} (r=0.46, r=0.35). The X-axis distance between corneal pupillary center and corneal apex was significantly positively correlated with J₄₅ (r=0.29). CONCLUSIONS In patients with advanced keratoconus after FBDALK, the unevenly distributed thickness at corneal pupillary area and the misalignment of corneal apex and pupillary center might cause significant regular and irregular astigmatism, which affected the postoperative visual quality.

OBJECTIVETo observe electrophysiological changes of severe N-hexane neuropathy getting active therapies and discuss its prognosis.

METHODSA follow-up study involved 16 adult severe N-hexane neuropathy patients who got active therapies was performed. EMG in right muscle of thenar, tibial muscle, and vastus medialis, NCV in right median nerve, common peroneal nerve, and sural nerve were determined and analyzed before treatment and in the first, the third, the ninth, and the twenty-fourth month after treatment.

RESULTSThe electrophysiology in severe N-hexane neuropathy patients showed that the voluntary potential during muscle relaxation increased by 25.0%; the motor unit potential time limit prolonged by 20.8%, and the amplitude increased by 12.5%, and multiphasic wave increased by 16.5% during mild contraction; the raise decreased by 25.0% during strong contraction. In control group, the MCV, SCV, SNAP, DML, and CMAP of median nerve were (54.63 +/- 5.33) m/s, (59.25 +/- 6.45) m/s, (26.53 +/- 6.32) microV, (3.96 +/- 0.65)ms, and (9.89 +/- 2.30) mV respectively, the MCV, CMAP, DML of common peroneal nerve were (48.49 +/- 3.25) m/s, (5.47 +/- 1.77) mV, (5.20 +/- 1.27) ms respectively, and the SCV, SNAP of sural nerve were (63.21 +/- 9.30) m/s, (4.63 +/- 1.29) microV respectively. Severe N-hexane neuropathy patients presented significantly different abnormalities in the NCV and EMG (P < 0.01). The MCV, SCV, SNAP, DML, CMAP of median nerve were (46.00 +/- 4.32) m/s, (40.66 +/- 2.65) m/s, (7.98 +/- 1.05) microV, (4.28 +/- 0.63) ms, and (6.32 +/- 1.54) mV respectively. The MCV, CMAP, DML of common peroneal nerve were (48.49 +/- 3.25) m/s, (3.21 +/- 1.99) mV, (7.32 +/- 1.65) ms respectively. The SCV, SNAP of sural nerve were (36.48 +/- 5.20) m/s, (2.15 +/- 1.22) microV respectively. These parameters gradually recovered to normal levels in 24 months after treatment.

CONCLUSIONThe electrophysiological abnormalities in severe N-hexane neuropathy patients can restore after treatment, and clinical prognosis is good.

OBJECTIVETo discuss the safety and the feasibility of laparoscopic selective portal inflow occlusion.

METHODSFrom January 2005 to February 2006, 7 patients were performed by laparoscopic hepatectomy with selective portal inflow occlusion. The patients included 1 male and 6 females, the mean age was 48.9 years, ranged from 31 to 70 years. Procedure included left lateral segmentectomies (4 patients), left hemihepatectomies (2 patients), and right hemihepatectomies (1 patient). Portal vein, hepatic artery and their branches were exposed by blunt dissection and performed selective portal occlusion with absorbable clips.

RESULTSThere is no conversion, no mortality, and no postoperative complication. Seven selective portal inflow occlusions were performed successfully. The mean operating time was 188.7 min (range 70 min to 300 min), the mean intraoperative blood loss was 625 ml (range 350 ml to 1000 ml), and the mean postoperative hospital stay was 8.4 days.

CONCLUSIONSLaparoscopic selective portal inflow occlusion is a safe and feasible technique.
