To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
● CONCLUSlON: Treating the primary angle - closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.

Objective To observe the effects of tetramethylpyrazine (TMP) on acute nociception in rat hindpaw induced by purine 2X (P2X) receptor agonists, such as adenosine triphosphate (ATP) and ?, ?-meATP, prostaglandin E 2 (PGE 2), and substance P (SP). Methods The effects of TMP administered intraplantarlly on the acute nociception induced by P2X receptor agonists, PGE 2, or SP in the rat hindpaw were investigated by the method of the behavioral study. Results TMP (10 mmol/L) significantly depressed the acute nociception induced by ATP (1 ?mol/L) or ?, ?-meATP (0.6 ?mol/L) in the rat hindpaw. TMP (10 mmol/L) could inhibit the acute nociception induced by PGE 2 (5 ?mol/L) or ?, ?-meATP (0.2 ?mol/L) coinjected with PGE 2 (5 ?mol/L). TMP (10 mmol/L) could not affect the acute nociception induced by ?, ?-meATP (0.2 ?mol/L) coinjected with SP (10 ?mol/L). TMP could not obviously affect the inflammatory edema in rat hindpaw induced by the local administration of PGE 2, SP, or ?, ?-meATP coinjected with PGE 2 or SP individually. Conclusion The antinociceptive effects of TMP may mainly be associated with inhibiting the transmission of nociceptive information mediated by P2X receptor activation.

ObjectiveTo investigate the application of surface electromyography (sEMG) in patients with lumbar disc herniation. Methods44 patients with chronic lumbar disc herniation were divided into mild pain group (group A) and moderate to severe pain group (group B) according to their scores of Visual Analogue Scale (VAS). Their sEMG at erector spinae and gastrocnemius were collected, and the average EMG (AEMG), slope of median frequency (MFs) were analyzed. ResultsCompared with those in the healthy side, AEMG of erector spinae and gastrocnemius reduced significantly (P<0.05) in affected side in both groups, while the MFs (absolute value) increased (P<0.05). Compared with those in group A, the MFs (absolute value) in affected side significantly increased in group B (P<0.05). The ratio of healthy/affected side of AEMG increased in group B (P<0.05), but the ratio of MFs was no significantly difference between 2 groups (P>0.05). ConclusionSurface EMG, of both the erector spinae and gastrocnemius, can be used as a non-invasive tool in detecting neuromuscular function of lumbar and lower limb in patients with lumbar disc herniation. The sEMG imbalance may respond with the severity of pain.

Objective To explore the quadriceps muscles function in patients with unilateral knee injury.Methods 23 unilateral knee injured patients with joint dysfuntion were assessed with isometric EMG activity of vastus lateralis (VL), vastus medialis obliques (VMO) and rectus femoris(RF) of both thighs during three 5-s maximal isometric voluntary contractions at a knee joint angle of 30° (0° - full knee extension), and the torque were recorded at same time. Results The average amplitude (AEMG), mean power frequency (MPF), and median frequency (MF) of VL, VMO and RF in affected knees were significantly lower than those in unaffected knees（P＜0.01）, as well as the torque（P＜0.01）. In the unaffected side, the AEMG, MPF of VL were higher than VMO and RF（P＜0.05）, and RF than VMO（P＜0.05）. In the affected side, the AEMG, MPF of RF are higher than VMO and VL（P＜0.05）, and VL than VMO（P＜0.05）. Conclusion sEMG can provide quantitative measurements of muscle function. The isometric strength and neuromuscular activation lever are lower in affected limb, RF may be affected less than VL and VMO in knee injured patients with knee dysfunction.

Objective To study the effects of found in inflammatory zone 1(FIZZ1) on the migration of cul- tured mouse vascular smooth muscle cell(VSMC) and the potential mechanism.Methods Using Boyden chamber, immunofluorescence and Western blot,the migratory effects,F-actin content and Akt/Akt1 expression were deter- mined in VSMC after stimulation by FIZZ1.Results FIZZ1 markedly increases the migratory ratio,F-actin con- tent and the Akt1 expression of VSMC.Ly294002,a PI3K inhibitor,attenuated migratory ratio,F-actin content and the Akt1 expression of VSMC promoted by FIZZ1 in a dose-dependent manner (10-30 ?mol/L).Conclusion Our data demonstrated FIZZ1 by activating PI3K/Akt1 pathway induced the expression of F-actin of VSMC,and promoted the migration of VSMC.

BACKGROUND: High-frequency jet ventilaion is considered a reliable technique for anesthesia and critical care including respiratory failure but there are adverse reactions such as carbon dioxide retension and dry of respiratory mucosa. The purpose of this study was to confirm the effects of combined high- frequency jet ventilation (HFJV) and converntional mechanical ventilation (CMV) on the cardiovascular system, arterial blood gases tension and mean airway pressure in 9 Korea mongrel dogs with pulmonary edema induced by oleic acid. METHODS: During CMV with 20 breaths/minute, 10 ml/kg of tidal volume and F1O2 1.0, parameers were evaluated (base line value). When pulmonary edema was developed, HFJV was applied initially with 120 breaths/minute, inspiratory time 30% and driving pressure 40 psi F1O2 1.0 for 60 minutes (control value) and thereafter simultaneous use of CMV was applied with the tidal volume of 10 ml/kg and each respiratory rate 8, 4, 2, 1, 0.5 per minute for 30 minutes. RESULTS: Combined application of HFJV and CMV (above repiratory rate 1 per minute) achieved the improvement of oxygenation and carbon dioxide elimination, and Paw was decreased without undesirable effects on cardiovascular system in case of the induced pulmonary edema. CONCUSIONS: From above results we recommanded that HFJV combined with CMV may be a useful method of treatment for respiratory failure.
