Objective To observe efficacy of percutaneous laser disc decompression (PLDD) and its correlation with plasma levels of β-endorphine and substance P in patients suffering from protrusion of lumbar intervertebral disc (PLIVD). Methods Seventy-eight patients with PLIVD were randomly divided into two groups, one group (40 patients) treated with PLDD and the other (38 patients) treated with lumbar spine traction and physical therapy as control. Their peripheral plasma levels of β-endorphine and substance P were measured before the procedure and one day, one week and four weeks after it, respectively.Meanwhile, the visual analogue scale (VAS)was applied to assess their pain index. Results Plasma level of substance P was (186±66) ng/L and (419±82) ng/L, and (127 +83) ng/L and (322 +47) ng/L,in treatment and control groups, one day and one week after the procedure, respectively, and that of β-endorphine was (313 ±27) mg/L and (187 ±56) mg/L, and (364 + 18) mg/L and (211 +39) mg/L,one day and one week after it, respectively ( all P ＜ 0. 01 ), with its clinical efficacy of 90% (36/40)and 66% (25/38) one week after it, respectively ( P ＜ 0. 01 ) . Four weeks after it, plasma level of substance P was (64 ±50) ng/L in treatment group as compare to that in controls (93 ±75) ng/L, and that of β-endorphine was (410 ± 21 ) mg/L and (317 ± 42 ) mg/L, respectively, with efficacy of 95% (38/40) and 84% (32/38), respectively. Conclusions Plasma level of substance P can be reduced and that of β-endorphine can be increased by PLDD in patients with PLIVD, thus relieving their pain.Measurements of substance P and β-endorphine can be used as objective indicators to evaluate clinical efficacy of PLDD.

AIM: To analyze the associated factors of poor vision after phacoemulsification operation.
METHODS:Clinical data of cases with poor vision after cataract phacoemulsification combined with IOL implantation from 341 patients(418 eyes) during Jan. 2015 to Jan. 2016 in our hospital were collected and logistic correlation analyzed.
RESULTS: The incidences of postoperative low vision were 10. 3% for one month after operation. Forty-three eyes were reported low vision, and 41 of 43 the patients with postoperative low vision had fundus oculi disease before operation, which included 20 eyes ( 48. 8%) with age-related macular degeneration, 16 eyes(39. 0%) with diabetic retinopathy, 3 eyes ( 7. 3%) with glaucomatous optic neuropathy, 1 eye(2. 4%) with pathologic myopia of retinopathy and 1 eye ( 2. 4%) with branch retinal vein occlusion.
CONCLUSION: The associated factors of poor vision after phacoemulsification operation are preoperative eye diseases and the nuclear hardness, and preoperative eye diseases may be the main causes of postoperative low vision. Comprehensive examination should be attached importance to, and be careful in the operation to decrease the harm for visual performance.

Objective To explore the anatomical basis for the flexor pollicis brevis branch of median nerve transfer to the deep branch of ulnar nerve.Methods Eight fresh upper limb were dissected and observed.The specimen were dissected under the loup.Observed the number of the flexor pollicis brevis branch and measured the distances from pisiform bone to the flexor pollicis brevis branch.Then the transfer operation on the cadaver were imitated.After the anastomosis was completed,the stumps of the nerves were sectioned and stained with HE.The crossing-sectional area and the density of nerve fiber were obtained by Image-Pro Plus version 6.0,then the number of the nerve fiber were calculated.The data analyzed by SPSS 17.0.Results The flexor pollicis brevis branch constantly appear,there were two branches in 2 specimens,one branch in 6 specimens.The flexor pollicis brevis branch could transfer to the deep branch of ulnar nerve by end-to-end surture without tension.The regeneration distances was (37.3 ± 5.76) mm.The crossing-sectional area were (0.0575 ± 0.0086)mm2 and (0.2039 ± 0.0396)mm2,the number were (492.50± 62.62) and (1651.13± 79.01),the density were (8781.4246 ± 1676.2894)/mm2 and (8371.1592 ± 1677.6509)/mm2 in the flexor pollicis brevis branch and the deep branch of ulnar nerve,respectively.There were no significant differences in the density of the nerve fiber between the donor and recipient nerve (P ＜0.05).But there were differences in the crossing-sectional area and number of the nerve fiber(P ＜ 0.05).Conclusion The flexor pollicis brevis branch transfer to the deep branch of ulnar nerve can provide a short regenerating distance,but can supply a part of recipient nerve to reinnervate.

OBJECTIVETo explore the nerve regeneration mechanism of electroacupuncture (EA) combined with polysaccharide of gastrodia elate blume (PGB) for secondary thalamic damage of focal cerebral ischemia.

METHODSForty Sprague-Dawley adult rats were randomly divided into a normal control group, a model group, an EA group, a PGB group and an EA + PGB group, 8 rats in each group. The rat model of right middle cerebral artery occlusion was prepared by suture-occluded method. Two weeks after model establishment, rats in the normal control group and model group received no treatment; rats in the EA group were treated with EA at "Baihui" (GV 20) and left "Zusanli" (ST 36), 30 min per treatment, once a day for 14 successive days; rats in the PGB group were treated with intragastric administration of PGB (100 mg/kg) , once a day for 14 days; rats in the EA + PGB group were treated with EA and PGB treatment, once a day for totally 14 days. The expressions of nestin and stem cell factor (SCF) in thalamic ventroposterolateral nucleus (VPL) were detected by immunohistochemical method.

RESULTSThere were positive cells of nestin in ischemia VPL in the model group, and the number of SCF positive cells was increased compared with that in the normal control group (P<0.05). The number of positive cells of nestin and SCF in ischemia VPL in the EA group, PGB group and the EA + PGB group was increased compared with that in the model group (all P<0.05), and the average gray value of immune positive product was all reduced (all P<0.05). The number of positive cells of nestin and SCF in the EA + PGB group was higher than that in the EA group or the PGB group (all P<0.05).

CONCLUSIONEA combined with PGB can significantly increase the SCF expression in ischemia VPL and promote the proliferation of neural stem cells, which is likely to be one of the nerve regeneration mechanism of acupuncture and medication tor secondary thalamic damage of local cerebral isctemia.

We herein reported a 27-year-old woman with a right renal mass for two years. She underwent laparoscopic partial nephrectomy. Immunohistochemical examination of the specimen confirmed the diagnosis of solitary fibrous tumor by revealing its positive staining for cluster of differentiation (CD)34, epithelial membrane antigen (EMA), B-cell lymphoma-2 (Bcl-2) and CD99 in the tumor cells. No adjuvant treatment was carried out. The patient was in good health without local recurrence or metastasis during 2 years of follow-up. Laparoscopic partial nephrectomy for renal solitary fibrous tumor is an alternative treatment to radical nephrectomy. It can provide a good outcome. However, further follow-up and more cases of renal solitary fibrous tumor treated with laparoscopic partial nephrectomy are necessary to compare the oncological outcome with radical nephrectomy.

AIM:To analyze the characteristics of optical coherence tomography ( OCT ) in diabetic optic neuropathy ( DON ) retrospectively.
●METHODS:Retrospective study. A total of 175 cases of type ll diabetes with fundus lesions from Dec. 2013 to Dec. 2015 were selected and the clinical information was collected. These cases were diagnosed by consultation between Departments of Ophthalmology and Endocrinology in the Second Affiliated Hospital of Xi′an Jiao Tong University. The results of body examination were recorded and cases were examined by color fundus photography, fluorescein fundus angiography ( FFA) and OCT. All these data were analyzed.
●RESULTS: A total of 49 cases ( 90 eyes, 25. 7%) were diagnosed DON through FFA which manifested abnormal fluorescence in optic papilla. Results of OCT showed:among 90 eyes of DON patients, 15 eyes ( 16. 7%) had normal optic nerve form; 20 eyes(22. 2%) of excavation of optic disc became smaller or disappeared, with prelaminar tissue and peripapillary retinal nerve fiber layer (RNFL) swelling;26 eyes (28. 9%) manifested optic cup deep and cup/disc ratio increasing;18 eyes (20. 0%) had tissue hyperplasia in the hollow or on the surface of optic disc; 11 eyes(12. 3%) had symptoms including vitreous traction optic papilla and optic disc rim rising. DON eyes which had similar fluorescence features could manifest different tissue morph by OCT.
●CONCLUSION: FFA defines DON by change of blood circulation in optic nerve. However, OCT can show differences of tissue morph of optic nerve that FFA fails to do. So OCT can manifest the causes and sites of optic neuropathy more clearly and also provide basis for treatment. The advantages of OCT are conducive to reviews and curative effect tracking among DON patients and these advantages including noninvasive, convenient, inexpensive and repeatable.

Objective To investigate the clinical outcomes of using modified antegrade digital artery island flap for the treatment of the severely flexion contracture of the burned finger.Methods Between August,2013 to August,2015,21 patients (21 fingers) with severely flexion contracture of the burned finger were hospitalized for treatment.According to the Stren classification standard for the interphalangeal joint flexion contracture,all the patients were rated as type Ⅲ.The volar soft-tissue defect with exposed tendons,nerves,vessels or bone ranged from 1.0 cm × 2.0 cm to 2.5 cm × 4.0 cm after scar relaxation.The artery and the nerve defect were 1.5 to 4.5 cm and 2.0 to 4.2 cm,respectively.The wound were reconstructed with the modified antegrade digital artery island flap.The dorsal branches of the proper digital nerve of the flap were anastomosised with the proper digital nerve of the wound.The flap donor site was resurfaced with full-thickness skin grafting from inner aspect of the forearm.All the cases were called back for postoperative follow-up.Results All the reconstructed fingers and flaps survived completely without vascular problems.The donor skin graft survived and wound healed by first intention.All the patients were followed up with 11.5 months (range,6-22 months).The finger appearance was satisfactory.The texture and color of flaps in all cases were good.There was no pigmentation and contraction relapse.The contracted fingers received no cold intolerance.At the final examination,the average values of static 2-point discrimination were 5.2 mm (range,4.3-6.5 mm) of the flap.In the series,based on the Michigan Hand Outcome Questionnaire,18 patients were strongly satisfied with the injured finger appearance and 3 patients satisfied with the appearance.Conclusion The modified antegrade digital artery island flap,which is easy to raise with large flap size and can result with the good finger appearance and function,is an ideal technique for reconstruction of the severe flexion contracture of the burned finger.

Aim To investigate the anti-tumor effects of FS-108 an Hsp90 inhibitor, on oncogene addicted EBC-1 and A375 cells. Methods SRB assay was performed to investigate cell proliferation. Immunoblot was conducted to investigate the specific proteins. FACS was conducted to test cell cycle distribution and apoptosis. Transwell assay was conducted to investigate cell motility. Results FS-108 significantly suppressed cell proliferation of EBC-1 and A375 cancer cells with IC50 at 25. 53 nmol · L-1 and 30. 02 nmol · L-1 re-spectively. FS-108 treatment triggered the degradation of key client proteins such as c-Met and B-Raf and thereby reduced their downstream AKT and ERK signa-ling pathways. The FACS analysis results demonstrated that FS-108 treatment induced G2/M phase arrest and apoptosis significantly. Furthermore, FS-108 inhibited the migration of EBC-1 and A375 cells. Conclusion As a potent Hsp90 inhibitor, FS-108 can inhibit onco-gene addicted cancer cells proliferation through induc-tion of G2/M phase arrest and apoptosis.

BACKGROUND:Recent studies found that some factors play important role in the process of denervated muscle atrophy, especial y the feak-headbox transcription factor, is the key element to regulate the denervated muscle atrophy.
OBJECTIVE:To investigate the effect of RNA interference on inhibiting feak-headbox 3a gene expression in vitro.
METHODS:The myoblast cel line L6 were cultured in the 6-wel cel culture plates, then pEGFP-N1 and smal
interfering RNA recombinant plasmid with the same ratio was transfected under the Lipofectamine2000 mediation to optimize the transfection efficiency of the detection system;2μg smal interfering RNA recombinant plasmid of feak-headbox 3a gene were transfected with myoblast cel line L6 for 48 and 72 hours.
RESULTS AND CONCLUSION:At 48 hours after pEGFP-N1 and siRNA recombinant plasmid transfection, a large number of bright green fluorescent displayed under fluorescence microscope with higher transfection efficiency. Real-time quantitative PCR analysis showed that there were significant differences in the sequences of feak-headbox 3a-Ⅰ, feak-headbox 3a-Ⅱ, feak-headbox 3a-Ⅲ, feak-headbox 3a-Ⅳ on feak-headbox 3a mRNA when compared with the control group at 48 and 72 hours after trasfection (P<0.05), and the inhibition effect was more significant at 72
hours after transfection when compared with that at 48 hours after transfection. Western Blot gray analysis showed that there were significant differences in sequences of feak-headbox 3a-Ⅰ, feak-headbox 3a-Ⅱ, feak-headbox 3a-Ⅲ,
feak-headbox 3a-Ⅳ on feak-headbox 3a mRNA when compared with the control group at 48 and 72 hours after
trasfection (P<0.05), and the inhibition effect was more significant at 72 hours after transfection when compared with that at 48 hours after transfection, which was same with the effect on mRNA level. RNA interference in vitro can
significantly inhibit the fork-head transcription factor feak-headbox 3a gene expression, and the inhibition effect of feak-headbox 3a gene smal interfering RNA recombinant plasmid transfected with the sequence on the mRNA and protein level of feak-headbox 3a is not clear, which can provide new idea for the gene therapy of RNA mediated denervated skeletal muscle atrophy.
