AIM:To explore and compare effect of coaxial micro-incision phacoemulsification and standard coaxial phacoemulsification in the treatment of cataract.
METHODS:A total of 88 patients(88 eyes) with senile cataract who underwent selective cataract ultrasonic emulsification resorption combined with intraocular lens implantation in the hospital from Aug. 2013 and Aug. 2015 were selected, they were divided randomly into the control group ( 44 cases, 38 cases completed, 6 cases dropped out ) and the observation group ( 44 cases, 40 cases completed, 4 cases dropped out ) . The control group received standard coaxial 3. 0mm small incision phacoemulsification, the observation group received coaxial 1. 8mm micro-incision phacoemulsification. All patients were combined with intraocular lens implantation. Intraoperative effective ultrasonic time, cumulative release energy, best corrected visual acuity before and after surgery in the two groups were recorded, corneal endothelium cell population, incision corneal thickness, percentage of cornea hexagon cell, corneal astigmatism changes before the operation, 1d, 7d, 30d after the operation were compared.
RESULTS: There was no significant difference in intraoperative effective ultrasonic time, cumulative release energy in the two groups(P>0. 05). There was no significant difference in postoperative best corrected visual acuity between the two groups(P>0. 05). Corneal endothelium cell population, percentage of cornea hexagon cell 1d, 7d, 30d after the operation in the two groups were significantly decreased compared with those before the treatment ( P < 0. 05 ), but there was no significant difference in the two groups ( P > 0. 05 ). Incision corneal thickness 30d after the operation in the observation group was significantly lower than the control group(P<0. 05). Degree of corneal astigmatism in the observation group 1d, 7d, and 30d after the operation were significantly lower than the control group (P<0. 05).
CONCLUSION: Coaxial micro - incision phacoemulsification and standard coaxial phacoemulsification can improve visual acuity of cataract patients, but the former can reduce degree of corneal astigmatism.

BACKGROUND: Results from clinical trials suggested that clopidogrel and ticlopidine had side effects of granulopenia, and aspirin could inhibit endothelial progenitor cell proliferation. There is no report of effects of these drugs on human bone marrow mesenchymal stem cells (hBMSCs) in stem cell transplantation. OBJECTIVE: To investigate the effects of antiplatelet drugs including clopidogrel, ticlopidine and aspirin on hBMSC proliferation and secretion. DESIGN, TIME AND SETTING: The cytology in vitro observation was performed at the Laboratory of Toxicology, Shanghai Municipal Center for Disease Control and Prevention from March to December 2006.MATERIALS: The second passage of hBMSCs was kindly donated from Shanghai Tissue Engineering Research & Development Center, Shanghai Ninth People's Hospital. Clopidogrel (Lot number J20040006) and ticlopidine (Lot number H19980186) were obtained from Hangzhou Sanofi-Synthelabo Minsheng Pharmaceutical CO., Ltd. Aspirin (Lot number 20050059) was obtained from Bayer Vital GmbH. METHODS: The standard culture medium consisted of DMEM-LG, 10% heat-inactivated FBS, 100 U/mL penicillin and 100 μg/mL streptomycin. After being cultured in vitro expanded out to passage 6, hBMSCs were treated with antiplatelet drugs of different concentrations and compared with control group. MAIN OUTCOME MEASURES: Cell proliferation was assessed by 3- (4, 5-dimethylthiazol -2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay, level of vascular endothelial growth factor (VEGF) of culture medium was detected by enzyme-linked immunoadsordent assay (ELISA), and surface antigens of hBMSCs were analyzed by the flow cytometry. RESULTS: A570 values of hBMSCs treated by clopidogrel or ticlopidine of 0.02,0.1,0.4,2,10,40 μmol/L were higher than control group (P < 0.01), while A570 values of aspirin group of 60, 600, 2 000 μmol/L were lower than control group(P < 0.05). Antiplatelet drugs had no obvious effect on cell surface antigens(CD34, CD105, CD106)expressed by hBMSCs. Treated by high dose clopidogrel or ticlopidine (40 μmol/L), VEGF level from hMSCs was lower than that of control group(P < 0.01), but VEGF level of low dose (0.02 μmol/L) ticlopidine group was higher than control group(P < 0.01), and there was no significantly difference of VEGF level among low dose clopidogrel group (0.02 μmol/L), aspirin group (5, 2 000 μmol/L), and control group(P > 0.05). CONCLUSION: Clopidogrel and ticlopidine improve proliferation of hBMSCs, but aspirin inhibits proliferation of hBMSCs. High dose of clopidogrel and ticlopidine suppress VEGF secretion of hBMSCs, while low dose of ticlopidine promote it. Antiplatelet drugs have no obvious effect on hBMSCs differentiation.

OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.

METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.

RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.

CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.

Objective To evaluate the effect of training for therapists based on Kirkpatrick's Four-level Model. Methods Totally 39 ther-apists who completed 2014 Beijing Clinical Shortage of Manpower Training Programs (Therapist) were investigated with Kirkpatrick's Four-level Model, named reaction, learning, behavior and results. Results For reaction level, the total satisfaction was high, but different with the degree of education, especially in the items of Participate in Training, Type of Cases, Organizing on Practice Training, Organizing Case Discussions and Get A Lot of Benefits from the Training (F>4.59, P<0.05). For learning level, the test scores were significantly differ-ent before and after the training (t>9.53, P<0.001). For behavior level, the self-reports of the therapists, and the reports from their depart-ment directors and colleagues all agreed that their ability improved after training (t>4.44, P<0.001). For results level, eleven therapists passed the rehabilitation therapist test, two therapists participated in some researches, and one published an article. Conclusion The thera-pists satisfied in the training, that may improve the ability of therapists to contribute to their organization.

[A BSTR ACT] OB J ECTI V E To i mprove the recognization of clinical, imaging and pathological characteristics of angioleiomyoma (ALM) in the head and neck region. METHODS We retrospectively reviewed the data of 20 patients with ALM in the head and neck region between 2000 and 2012. RESULTS Seven male and 13 female patients were included in this study. The average age was 52.5 (from 28 to 74 years). The symptom in most cases (n=14) was the painless mass, 4 tumors originating in the nasal cavity presented with nasal obstruction or (and) epistaxis, and the other 3 cases were accidentally found by physical examination. The results of B-ultrasonography in 10 ALM cases of subcutaneous or deep space were homogeneously hypoechoic echo texture, straight and linear vessels in the tumor with convergence to one point with a circumscribed margin. MRI in 5 cases demonstrated typically a well-defined mass, which showed hypointensity or isointensity to muscle on T1WI, and heterogeneous hyperintensity on T2WI. All lesions showed obviously delayed enhancement on contrast MRI. HE stain showed that the tumors were formed by bundles of spindle-shape smooth muscle cells circumscribing numerous slit-like blood vessels in most cases. Immunoperoxidase staining revealed that the tumor cells were strongly positive for calponin, desmin and smooth muscle actin (SMA) in the cytoplasm of the smooth muscle cells. The positive expression of progestogen receptor and estrogen receptor was seen in 7 cases and 4 cases respectively among 10 cases. All patients underwent surgery, and recovered well postoperatively without recurrence or malignancy. CONCLUSION The clinical manifestations of ALM are nonspecific. ALM has distinctive imaging features in B-ultrasonic and MRI examination. Histological examination and immunoperoxidase staining can make a definite diagnosis of the disease. Progestogen receptor and estrogen receptor can be expressed in ALM. The postoperative prognosis is good.
