Objective To report the clinical and imaging characteristics of 9 cases of gastric duplication in children,as well as to probe into all kinds of imaging examination methods,with an aim to improve preoperative diagnostic accuracy.Methods Nine cases of children with gastric duplication that received surgical resection and were pathologically confirmed in our hospital from January 2009 to November 2016 were retrospectively analyzed.The clinical manifestations,complications,complicated malformation and imaging findings of the cases were summarized.Three asymptomatic cases were carried out regular ultrasound examination follows-up preoperatively.Results Gastric duplication in children varied in terms of cliuical manifestations.All the 9 cases were performed ultrasonography preoperatively,and 5 of them were accurately diagnosed.Meanwhile,7 cases received preoperative CT examination,with 2 cases being confirmed.Three cases received magnetic resonance imaging (MRI) examination,with 2 cases being confirmed.And 2 cases had upper abdominal gastrointestinal imaging (GI) examination,but no definite diagnosis was made.Three cases of asymptomatic children with enlarged lesion can be seen in follow-up.Conclusions Gastric duplication is a rare congenital malformation,ultrasound allows to clearly display the capsule wall structure and the relation between gastric duplication with gastric wall,which is associated with high utilization rate and diagnosis rate,and it can be served as the preferred imaging examination method for gastric duplication in children.

Doctors in the past dynasties always used ephedra to treat disease of exogenous wind-cold,cough,asthma and edema,but ignored its application in treating arthromyodynia.It could be deduced from the record of the books of Chinese medicine and prescriptions that ephedra had the nature of pungent and warm,could dispel wind and remove wetness,warm channel and expel cold,remove obstruction in collaterals.All of those were correspondent with the pathogenesis of arthromyodynia.Thus,ephedra can be widely used in types of arthromyodynia.Proven case was also included in this article.

Objective To evaluate and compare the cellular immune response induced by live at-tenuated and inactivated hepatitis A vaccines. Methods A total of 18 healthy volunteers were enrolled in this study. They were divided randomly into 2 groups and injected by inactivated hepatitis A vaccine and at-tenuated hepatitis A vaccine, respectively. All volunteers' heparinized venous blood was separately collected for testing anti-HAV antibody and the responses of PBMC. The level of IFN-γsecreted by effect T cell was tested by ELISPOT. The percentage of lymphocytes secreting IFN-γ from CD+ and CD8+ T cell was tested by intracellular cytokine staining (ICS) technique. The concentrations of IFN-γ, IL-2, IL-10 and IL-4 in the culture supernatants(grown in the presence or absence of HAV) of the in vitro HAV-primed PBMC were determined by Luminex. Results These two types of vaccines can elicit specific anti-HAY antibodies and no statistical significance between them were observed. At the early stage after inoculation, T cell-mediated immune responses with the secretion of IFN-γ were detected in vaccines inoculated with either type of vac-cines. There was a tendency that the cellular immune responses level induced by inactivated hepatitis A vac-cine was higher than that by live attenuated hepatitis A vaccine during 1 to 3 weeks post-injection. The booster inoculation could significantly increase the level of cellular immune responses induced by the inacti-vated vaccine. Conclusion Both live attenuated and inactivated HAV vaccines can elicit an earlier specific humoral and cellular immune responses, and booster inoculation of inactivated HAV vaccine can rapidly and intensively evoke memory immune responses.

Objective To study the short-term clinical outcomes of unicompartmental knee arthroplasty for medial compartmental knee osteoarthritis,and to compare 2 kinds of unicompartmental prosthesis.Methods From March 2010 to June 2013,data of 43 patients underwent unicompartmental knee arthroplasty (UKA) were retrospectively analyzed.17 patients (17knees) used rotating platform prosthesis,and 26 patients (28 knees) used fixed bearing prosthesis.There were 7 males (7 knees)and 9 females (10 knees) in rotating platform group,with an average age of 64.1 years (range,54-82 years);while 10 males (10knees) and 17 females (18 knees) in fixed bearing group,with an average age of 62.2 years (range,43-79 years).All patients presented signs of narrowed medial joint space,medial tenderness and pain on weight-bearing.X-ray and MRI were used for documenting joint narrowing and cartilage defect.The pain and the knee functions were recorded both pre and post-operatively with knee society score (KSS),2 cases of simultaneous anterior cruciate ligament (ACL) reconstruction were assessed with TegnerLysholm knee scoring scale as well.Results All 43 patients were followed up for 6 month to 37 months,and the average duration was 21.1 months.There were no dislocations,joint infection,deep venous thrombosis,prosthetic loosening,etc.The KSS in rotating platform group was 56.11 ±9.51 preoperatively,and 92.23±5.46 postoperatively.While the KSS in fixed bearing group was 57.11 ±9.56,and 93.69±6.37,respectively.There were statistical differences comparing between preoperative and postoperative KSS knee scores.There was no significant difference in KSS scores between rotating platform group and fixed bearing group.Conclusion Unicompartmental knee arthroplasty is a less invasive and effective method for knee osteoarthritis in medial compartment with less complications.There was no significant difference in clinical outcomes between rotating platform and fixed bearing design in terms of patients' satisfactory rate,clinical and functional outcomes in this short-term follow-up study.

AIM: To study the effect of the overexpression of p16 on an anion exchange function of band 3 in HeLa cells. METHODS: The expression of p16 and band 3 in HeLa cells was detected by immunohistochemistry (IHC). The p16 cDNA was subcloned to plasmids pEGFP-C1 by PCR and identified by restriction enzyme digestion and sequencing, and then, the recombinant pEGFP-C1-p16 plasmids were transiently transfected into HeLa cells. The expression of fusion protein in HeLa cells was detected by fluorescence microscope. 6-methoxy-N-(3-sulfopropyl)-quinolinium(SPQ)fluorescent probes were used to detect the anion exchange function of band 3. RESULTS: P16 and band 3 were expressed in HeLa cells. The amplificated p16 cDNA sequence was the same as the report sequence. The transfective efficacy of pEGFP-C1-p16 was above 60%. The anion exchange function increased after the transfection of pEGFP-C1-p16 plasmids. CONCLUSION: p16 facilitates the anion exchange function of band 3 in HeLa cells.

BACKGROUND: Dopamine is closely associated with occurrence of epilepsy and transmission in central nerval system, and its various functions are determined by specific receptors.OBJECTIVE: To establish temporal epilepsy model so as to probe into the influences of SCH23390, the antagonist of dopamine D1 receptors and haloperidol, the antagonist of dopamine D2 receptors injected in substantia nigra on temporal epileptic seizure induced by kainic acid and on electroencephalic activityDESIGN: Randomized controlled verified experiment.SETTING: Neurology Medicine Institute of Zhujiang Hospital Affiliated to Southern Medical University.MATERIALS: The experiment was performed in General Military Neurology Medicine Institute of Zhujiang Hospital Affiliated to First Military University of Chinese PLA from August to December 2004, in which, 30SD adult male rats were employed, massed varied from 250 to 300 g.METHODS: ① 30 rats were randomized into physiological saline (control) group (6 rats), kainic acid (KA) group (6 rats) and experimental group (18 rats). The experimental group was divided into 3 subgroups, named the antagonist of dopamine D1 receptors, SCH23390 + kainic acid group (D1 +KA group), the antagonist of dopamine D2 receptors,haloperidol + kainic acid group (D2+KA group) and physiological saline + kainic acid group (PS + KA group), 6 rats in each. In the control, physi ological saline 2 μL was injected in the right cerebral ventricle unilaterally. In KA group, kainic acid 2 μL was injected in the right ventricle. In each of experimental group, SCH23390, the antagonist of dopamine D1 re ceptors, haloperidol, the antagonist of dopamine D2 receptors and physio logical saline 1 μL for each was injected in substantia nigra on the right side successively and simultaneously, kainic acid 2 μL was injected in the right ventricle. ② Observed items: alters of EEG on the 0.5th 1st, 2nd, 6th and 24th hours after medication in each experimental group (compared with EEG of non-epileptic behavior, appearance of sharp wave, spike wave,sharp (spike) slow comprehensive wave and multi-spike slow wave determines epileptic activity) and changes in animal behaviors (0 grade: normal; Ⅰ grade: wet dog-like trembling, paroxysmal facial spasm, like winking,beard moving, rhythmic chawing; Ⅱ grade: rhythmic nodding; Ⅲ grade:paroxysmal spasm of anterior limbs; Ⅳ grade: paroxysmal spasm of bilateral anterior limbs when standing; Ⅴ grade: falling down, loss of balance and convulsion of four limbs). Cerebral hippocampal neural cell apoptosis was observed and the rats were sacrificed on the 5' day of medication. Cerebral hippocampal section was prepared and determined after in situ end labeling staining.MAIN OUTCOME MEAUSRES: ① Changes in behavior in rats before and after epilepsy and electroencephalogram (EEG) alters. ② Results of cerebra hippocampal neural cell apoptosis.RESULTS: Thirty rats entered result analysis. ① Epilepsy seizure: In the control group, there was no epilepsy attacked. In KA group, all of rats ap pear seizure, which attacked 10 minutes after KA injected in brain ventricle, reached the peak in 1 hour and stopped in 3 to 6 hours. ② EEG record: In the control group, there was not epileptic activity manifestations,like sharp wave, spike wave, spike slow comprehensive wave, etc. In KA group, epileptic wave presented in 10 minutes after injection, the seizure developed to the peak in about 1 hour, the wave amplitude was decreased in 3 to 6 hours, presenting paroxysmal slow and spike slow waves and no epileptic wave appeared after 12 hours. ③ Neuronal apoptosis: In the control group, few neural cell apoptosis was visible in hippocampus after injection.In KA group, neural cell apoptosis was visible obviously in hippocampus in 5 days after injection (P =0.00). With SCH23390, the antagonist of dopamine D1 receptors, hippocampal cell apoptosis was not reduced remarkably (P ＞0.05) and with haloperidol, the antagonist of dopamine D2 receptors injected in substantia nigra, hippocampal cell apoptosis was aggravated (P =0.00).CONCLUSION: Injection of SCH23390, the antagonist of dopamine D1 receptors in substantia nigra cannot block kainic acid inducing epilepsy and epileptic electroencephalic activity is not weakened remarkably. Injection of haloperidol,the antagonist of dopamine D2 receptors enhances epileptic electroencephalic activity in kainic acid induced epilepsy and increases cell apoptosis remarkably in cerebral hippocampal CA3 area.It is to explain that it is dopamine D2 acceptor that is involved in regulation of temporal epilepsy in substantia nigra rather than D1 acceptor.
