Objective To explore the echocardiography characteristics of non-compaction of ventricular myocardium(NVM),and assess its value in the diagnosis of NVM.Methods Philips SONOS 5500 color Doppler ultrasound system with 2-4 MHz transducers was used in 9 patients with NVM.Results In all 9 patients,the presence of multiple trabeculations and multiple deep intertrabecular Space communicating with the ventricular cavity was demonstrated by color Doppler imaging.Both ventricles were involved in 1 patient,only the left ventricle in 7 patients,and right ventricle in 1 patient.Conclusions NVM has typical ultrasonic appearance on echocardiography.It Can find out the NVM manifestations even if patients do not have any symptoms.It is a reliable and convenient way for diagnosing NVM.

Background Wearing of soft contact lens,as one of the important methods to correct ametropia,has been widely applied at present.The clinically deleterious effects of soft contact lens have been reported,but researches about influence of apoptosis of corneal epithelial cells are scant.Objective This study was to detect and compare the ratio of apoptosis of corneal epithelial cells between the patients with contact lens wearing and without contact lens wearing,and explore the influence of soft contact lens wearing for long term on growth of corneal epithelial cells after injury.Methods A retrospective nest case-controlled study was designed.Forty eyes of 20 myopic patients with wearing of soft contact lens for ≥5 years and 40 eyes of 20 myopic patients without wearing of soft contact lens were included in Affiliated Hospital of Guiyang Medical College.All the patients received the off-flap epipolis laser in situ keratomileusis (Epi-LASIK) from 2010 October to 2011 June.The corneal flaps were collected during the surgery.The apoptosis of corneal epithelial cells was detected by flow cytometry(FCM),and the difference of apoptotic proportion between the two groups was compared using independent sample t test.Results The FCM scatter plot showed that compared to the without contact lens wearing group,the early stage of apoptotic cells with high staining annexin V and low staining proaium iodide (PI) were much more,and survival cells with low staining annexin V and PI were less,and necrotic and late stage of apoptotic cells with high staining of annexin V/PI were more in the with contact lens wearing group.The early stage of apoptosis proportion of corneal epithelial cells was (11.23 ± 5.31)％ in the with contact lens wearing group,and that in the without contact lens wearing group was (7.31± 5.43)％,showing a significant difference between them (t=2.754,P=0.008).Conclusions A long term wearing of contact lens induce more apoptosis of corneal epithelial cells,which can result in a disorder of structure and function of ocular surface during the wound healing stage.

To observe the clinical efficacy of diclofenac sodium eye drops for postoperative recurrence of pterygium, and to provide safer drug regimens to prevent the recurrence of pterygium.
● METHODS: From November 2011 to September 2013, 124 patients 134 eyes who underwent surgery because of pterygium in our hospital were randomly divided into trial group ( diclofenac sodium eye drops and sodium hyaluronate eye drops) and control group ( tobramycin dexamethasone eye drops and sodium hyaluronate eye drops), all patients were followed up for 3mo ( once a week ) and the cornea, intraocular pressure and recurrence of pterygium were observed and compared between the two groups.
●RESULTS: Followed up for 3mo, 43 cases (45 eyes) in the trial group and 38 cases (39 eyes) in the control group had done the follow up as planned, in which 14 cases (15 eyes) showed the signs of recurrence, 2 cases (3 eyes) recurred eventually in the trial group, and in the meantime there were 12 cases (13 eyes) with signs of recurrence and 2 cases ( 2 eyes ) with a recurrence eventually in the control group, but no statistical difference was found between the two groups (P>0. 05);there were 6 cases (9 eyes) dropped out of the study with a higher intraocular pressure in the control group, compared to trial group (0 cases of 0 eye), the difference was statistically significant ( P < 0. 05); cornea conditions between the two groups had no statistical significance (P>0. 05).
●CONCLUSlON:Diclofenac sodium eye drops is effective and safe in preventing the recurrence of pterygium.

·AIM:To report a case of entry of antibiotic ointment into the anterior chamber following sutureless clear corneal incisions phacoemulsification.·METHODS:A 62-year-old man had uneventful phaco-emulsification with clear corneal incisions with intraocular lens(IOL) implantation. Postoperative medication included antibiotic/steroid ointment; the eye was firmly patched at the end of the procedure. On the first postoperative day, the patient was seen an oily droplet floating in the anterior chamber. Immediate surgical removal of the ointment without IOL exchange was performed.·RESULTS:During follow-up for six months after irrigation/aspiration of the anterior chamber and removal of the oily droplet, visual acuity and intraocular pressure (IOP) were unchanged and anterior segment was formed and quiet.·CONCLUSION:Ophthalmic ointment may ingress into the anterior chamber through unstable clear corneal incisions. The case highlights the importance of appropriate wound construction and integrity, as well as the risk of tight eye patching following placement of ointment.

ObjectiveTo study the protection of Chinese herbs on the ischemic brain of rats. Methods 75 Wistar rats were divided into 5 groups, Group 1 for false operation. For the other four groups, the common carotid artery was exposed then was ligatured and cut off, Group 2 for model. From the 20th hour after operation on,Group 3, 4, 5 were fed with complex prescription of Chinese medicine named Prescription 1, 2 and 3 once a day respectively. 3 hours after taking medicine, Groups 2-5 were put in the hypoxia environment for 1 hours, then taking the medicine for 7 days. On the 7th day after operation,the blood was taken from R. atria then the rats were killed and the whole right brains were cut off. Malonaldehyde (MDA), notric oxide synthetase (NOS) and superoxide dismutase (SOD) in the brain tissue and serum, and calcium in the brain were measured respectively. ResultsThe three prescriptions can decrease the quantity of MDA both in brain tissue and serum and the calcium in brain tissue(P<0.05-0.001).Prescription 1 can enhance the activity of SOD in brain tissue while the others can decrease the activity of NOS. The hippocampus cells show tidy, and the number of the necrotic cells decrease greatly among them, Groups 4 and 5 are better than Group 3.Conclusions Prescriptions 1-3 can protect the brain tissue of the rat form ischemic brain injury.

The traditional culture methods and the molecular biology methods were used to study the rhizosphere bacterial diversity between fusarium wilt resistant and susceptible watermelon. The results showed that the diversity and the equality of cultured rhizosphere bacteria of resistant watermelon were higher than those of the susceptible watermelon. The reason was that the cultured rhizosphere bacterial di- versity index H′ and 1/D of the resistant watermelon were higher than those of the susceptible watermelon and that the cultured rhizosphere bacterial equality index E of the resistant watermelon were higher than those of the susceptible watermelon. The dominant cultured bacterial genotypes were different between re- sistant and susceptible watermelon. The genotype 1 is the dominant genotype of resistant watermelon, con- sists 51.1%. The genotype 7 is the dominant genotype of susceptible watermelon, consists 58.7%.

Objective To explore whether human umbilical venous endothelial cells could be used as feeder layer to support the growth of embryonic stem cells (ESC) and keep ESC undifferentiated.Methods The venous vessels of umbilical cord obtained from healthy puerperal were perfused with collagenase.The isolated endothelial cells went through primary culture and passages for expansion.Factor Ⅷ antigens determination was implemented.Endothelial cells with good growth and 3 or above passages were treated with mitomycin-C(10 mg/L) and prepared as feeder layer,on which E14.1 ESC was transplanted for subculturing to observe the morphological characterization and determine ESC alkaline psphatase (AKP) activity and the expression of stem cell marker Oct-4.Severe combined immune deficiency(SCID) mouse in vivo terotoma formation experiment was performed to identify its pluripotent properties.Results Human umbilical vein-derived endothelial cells grew well in culturing in vitro and regenerate in large numbers.The endothelial cells maintained normal cellular morphological and biological characterization after 10 passages.The cells stopped proliferating after being treated with mitomycin-C,but its activity and morphological properties were well-maintained with 24 hours,which was a fundamental property of serving as feeder layer.E14.1 ESC remained undifferentiated in human umbilical venous endothelial cells after 3-8 passages,the cells grew in colony and showed high expression of AKP and stem cell Oct-4.In vivo pluripotency experiment showed that 6 weeks after being transplanted to SCID mice E14.1 ESC of 6 and 10 passages in endothelial cells both could form teratoma containing 3 layers of tissue cells.Conclusions Human umbilical venous endothelial cell serve as a convenient feeder layer cell with rich sources.It can effectively support ESC growth and heterogenous and prevent the heterogeneous protein pollution and pathogenic microorganisms caused by animal cell feeder layers,thus solve the problem of biological safety of ESC clinical application.

Objective To evaluate the clinical effect of breast implant on congenital mammary dysplasia with mild pigeon chest deformity. Methods From January 2003 to July 2009,10 cases of female mammary dysplasia (between 20 to 31 years of age) underwent breast implant surgery. Subpectoral placement and transaxillary incision were selected. The surgeon marked the range of the operation on the skin, made a 3-4 cm incision in the armpit, separated the tissue until the pectoral lateral margin, cut the pecto-ralis fascia and bluntly created a suitable pocket under the pectoralis major for the implant. After the implant was placed in the pocket, the incision was closed. Results Ten cases of breast implant surgery did not pose the complications of local skin necrosis, infection, implant shift, heart and lungs dysfunction after one year follow-up. The appearance of anterior chest wall deformity was markedly improved. Conclusions The application of breast implant surgery in the treatment of congenital mammary dysplasia with mild pigeon chest deformity should be promoted, because of the double surgical effect of easy performing, minimal surgical damage, perfect breast shape and concealed deformity.

To compare the pharmacokinetics of syringin, eleutheroside E and isofraxidin after intravenous administration of each monomer and Ciwujia injection. Twenty-four Sprague-Dawley rats were randomly divided into four groups and intravenously administrated with syringin, eleutheroside E, isofraxidin, and Ciwujia injection, respectively. The concentrations of the three components in rat plasma were determined by LC-MS/MS. DAS 2.0 software was applied to calculate the pharmacokinetic parameters while the SPSS 17.0 software was used for statistical analysis. Significant difference (P < 0.05) was found between each monomer and the injection on the main pharmacokinetic parameters such as AUC, CL and t1,/2. Compared with the injection, the group treated with the syringin has obvious decrease in AUC, and increase in CL while the group treated with eleutheroside E has obvious increase in AUC, and decrease in CL The t1/2 of isofraxidin was prolonged in Ciwujia injection. Pharmacokinetic characters of the ingredients in the injection varied greatly from the monomer. Other constituents in the injection may have an impact on the pharmacokinetic profiles of these three components.
