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.

OBJECTIVETo explore early clinical effect of acetabular cup in total hip replacement for the treatment of Crowe II developmental dysplasia of hip.

METHODSEighteen patients (18 hips) with Crowe type II developmental dysplasia of hip were treated with total hip replacement from September 2001 to July 2013. Among them,including 13 males and 5 females aged from 42 to 60 years old with an average of 47.6 years old; the courses of diseases ranged from 9 to 22 years with an average of 13.5 years. All the patients had hip joint pain, limb shortening and limited hip function before operation. Harris score of hip joint were used to evaluate recovery of function at 1 day and 12 months after operation. Prosthetic coverage of acetabular cup at 1 week after operation was observed by using radiography.

RESULTSEighteen patients (18 hips) were followed up from 12 to 24 months with an average 17 months. All incisions were healed at stage I. No deep vein thrombosis, hip dislocation, periprosthetic joint infection and prosthesis loosening were occurred. No revision surgery during follow-up period. Prosthetic coverage of acetabular cup was more than 80% at 1 week after operation. Harris score were increased from 42.67 ± 5.06 before operation to 94.79 ± 3.27 at 12 months after operation (t = -45.269, P < 0.001).

CONCLUSIONFor type Crowe II developmental dysplasia of hip patients, 15° face-changing acetabular cups in THR could obtain higher actebular component coverage rate and satisfactory early clinical effects.

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.

Although current synthetic anti-gout drugs have significant therapeutic effects in reducing serum uric acid levels, they have serious side effects such as allergic reactions and liver and kidney damage. Natural products with a wide range of uric acid-lowering and high safety have played a critical role in anti-gout drug discovery and development. This paper reviews the natural products with uric acid-lowering or anti-gout pharmacological effects and the investigation on their mechanisms of action, to provide information for drug discovery and development.

The zinc chloride and cystine resistant strain of S.cerevisiae YZM-14(ZnCl2r,Cysr) was screened with the mutant processing of the protoplast of S.cerevisiae by combinative mutagens of ultraviolet and nitrite.The glutathione(GSH) production(84.72 mg/L),dry cell weight(7.63 g/L) and the intracellular GSH content(11.10 mg/g) of YZM-14 were 2.79,1.63 and 1.71 times compared with that of the initial strain.The biosynthetic process of GSH was divided into three phases according to the time course of the specific cell growth rate and GSH yielding coefficient.In the second phase,the metabolic flux of the pentose phosphate pathway and the GSH precursors biosynthetic pathway of the mutant strain increased by 8.1 mmol/(g?h),compared with that of the initial strain.Furthermore,the metabolic flux of the organic acids secretion of the mutant strain decreased.Through these mechanisms,the utilization efficiency of the carbon sources was enhanced and high production of GSH was obtained.

Objective To investigate the anti - stress activity of thymopentin ethyl ester. Methods Anti - stress activity was evaluated by heat stress model and chronic uncontrolled stress model. Heat stress model;of 60 KM mice were divided into six groups. Except the controlled group, the other mice were maintained in 42℃ for 1h. Chronic uncontrolled stress model:of 60 KM mice were divided into six groups. Except the controlled group, the other mice were given three different stimulations once a day for continuous 21 d. The controlled group and model group were injected saline 0.2ml, and the three test groups were respectively injected thympentin ethyl ester at 2mg/kg,0.2mg/kg, 0.02mg/kg subcutaneously. The positive controlled mice were given thymopentin 0.2mg/kg subcutaneously. At the end of the experiment, plasma corticosteroid, IL -2 and SOD were determined according to the kit instructions. Results The activities of thymopentin ethyl ester in suppressed corticosteroid up - regulation and the elevated plasma IL - 2 and SOD level were more significant than those of thymopentin(P

OBJECTIVETo refine the loss of heterozygosity (LOH) on chromosome 5p15 and screen new tumor suppressor gene(s) in colorectal tumorigenesis.

METHODSSamples of colorectal cancer and normal tissue of 83 cases were collected in this study. Sixteen polymorphic microsatellite markers were analyzed on chromosome 5 and another 6 markers on chromosome 5p15 by PCR. PCR products were electrophoresed on an ABI 377 DNA sequencer. Genescan 3.1 and Genotype 2.1 software were used for LOH scanning and analysis.

RESULTSTwo distinct regions of frequent allelic deletions at D5S416 on 5p15 and D5S428-D5S410 on 5q were detected. Another 6 polymorphic microsatellite markers were applied to 5p15 and the minimal region of frequrent loss of heterozygosity was established on 5p15 spanning the D5S416 locus.

CONCLUSIONA critical and precise location of 5p deletions, 5p15.2-5p15.3, has been detected, which may contain one or more unknown tumor suppressor gene(s) related to colorectal cancer.
