?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.

BackgroundResearches demonstrated that the levels of soluble CD44 (sCD44)molecule in aqueous is significantly higher in primary open-angle glaucomous(POAG) eye than normal eye,but how the sCD44 would affect the expression of apoptosis protein in trabecular meshwork cells is below understanding.Objective The present study was to investigate the effect of sCD44 on the expression of regulatory proteins bcl-2 associated death factor bad in trabecular meshwork cells in the patients with POAG.MethodsHuman scleral tissue with trabecular meshwork were obtained from POAG patients during the surgery.The trabecular meshwork cells were primarily cultured by explant culture method and identified by immunochemistry.The third generation of cells were incubated with free-serum DMEM/F12 medium added differnt dosages of sCD44 (0,1,5,10,25,50 mg/L) for 48 hours.The expression of bad protein in cultured cells was detected using cell counting kit-8 (CCK-8) as the absorbance values at 490 nm(A,90 value),and the bad protein level in cultured cells was assayed by ELISA.ResultsThe cultured cells showed the positive response for laminin ( LM ),neuron specific enolase ( NSE ),fibronectin ( FN ) monoclonal antibodies.The CCK-8 assay showed that the A490 values of the trabecular meshwork cells in 0,1,5,10,25,50 μg/L of sCD44 groups were 0.2460±0.0019,0.1874±0.0015,0.1570±0.0016,0.1302±0.0019,0.1084±0.0018,0.0940±0.0020 respectively with a statistically significant difference among the 6 groups( F =14.922,P =0.000 ),and the A490 values in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group (P=0.013,0.008,0.011,0.005,0.004).The ELISA assay showed that bad protein levels in 0,1,5,10,25,50 μg/L of sCD44 groups were ( 114.8461 ± 2.9560 ),( 137.8270 ± 2.4259 ),( 161.4194 ± 3.7381 ),( 170.9453 ± 3.2006 ),( 221.2252 ±4.3738 ),( 324.6167±4.4220) ng/L,showing a total difference among them ( F =16.610,P =0.000 ),and the bad protein levels in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group( P =0.017,0.013,0.008,0.007,0.006).ConclusionssCD44 can contribute to the apoptosis of the trabecular meshwork cells in patients with POAG in certain dose range by regulating the apoptosis regulatory proteins bcl-2 associated death factor bad.

OBJECTIVETo explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.

METHODSSix fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed. Based on the anatomic study, the perforator flaps were designed to reconstruct soft tissue defects at dorsum of hands and wrists. The redundant fat on the flaps was removed, but preserving the nutrient vascular system. 11 flaps were used with the size ranging from 2 cm x 5 cm to 10 cm x 14 cm.

RESULTS43 skin perforators of posterior tibial artery were observed in six lower limbs, 29 perforators with the outer diameter is greater than 0.5 mm when they threading over the deep fascia plane, on average every 4.8 bundles of sides. The mean outside diameter of perforating artery is (1.8 +/- 0.5) mm, and the length is (44 +/- 15) mm. 6 perforators were founded both in the second and fifth zone which could be used for anastomosis for its better diameters. All flaps survived completely without any complication at donor sites. 7 cases were followed up for 3-12 months. Both satisfactory functional and cosmetic results were achieved with a soft and thinned appearance.

CONCLUSIONSThe thinned posterior tibial artery free perforator flap has a reliable blood supply and good appearance. It is very suitable for the reconstruction of small or medium-sized defects at the dorsum of hands and wrists.

OBJECTIVETo investigate the therapeutic mechanism of point 8L54-through-point ST2S acupuncture with elongate needles in treating urinary retention after spinal cord injury.

METHODSThirty-five healthy Japanese rabbits (weight 2.5 +/- 0.25 kg, 3 months old, male or female), used as experimental subjects, were divided into 4 groups involving blank group, model group, acupuncture group, elongate needles group (5 rabbits in blank group, 10 rabbits in each of the other group 10). Modified Allen's method was used to cause spinal cord injury model for the model group, the acupuncture group and the elongate needles group, the blank group was only sham surgery. Immediately after spinal cord injury model,the elongated needle group was given the bilateral acupoints of the elongated needle penetration needling and electric stimulation, electrical stimulation 15 mm stimulation frequency of 20 to 40 times/mm, intensity 1.5 to 3 V the acupuncture group immediately was given ordinary electric needle acupuncture, given other disposals as the elongated needle group; model group was not given electric needle acupuncture, waiting 15 minutes, started to detect and record the observed indicator as the elongated needle group; the blank group was only sham surgery. The following indicators including the Tarlov score ,urinary bladder pressure point, the threshold urination, voided volume, were observed in the first day and the fifth day after surgery.

RESULTSThree groups of animals which modeled were urinary retention after operation. Compared to 1 d, Tarlov score of model group, acupuncture group and elongate needles group significantly improved at postoperative 5 d (P < 0.05). Compared with acupuncture group, the Tarlov score of elongate needles group had no significant difference at postoperative 5 d (P > 0.05). Compared with model group, values of urinary bladder pressure point decreased with varying degrees in the acupuncture group and elongate needles group at postoperative 5 d (P < 0.05); relative to the acupuncture group, the point of the bladder voiding pressure in the elongate needles group decreased more significantly at postoperative 5 d (P < 0.05); compared with model group, micturition threshold of acupuncture group and elongate needles group had been significantly improved at the fifth day after surgery (P < 0.05); relative to the acupuncture group, the improvement is more obvious in the elongate needles group. Compared with model group, voided volume of acupuncture group and elongate needles group had increased significantly at the fifth day after surgery (P < 0.05); relative to the acupuncture group, the increment is more evident in the elongate needles group (P < 0.05).

CONCLUSIONTo treat urinary retention after spinal cord injury, the method, which was point-through-point acupuncture with elongate needles in the "Zhibian" and "Shuidao", was better than general acupuncture method. The therapeutic mechanism may be related to stimulate peripheral nerve of bladder, and to rectify the dysfunction between detrusor and sphincter.
