Objective To study and evaluate the consistency and diagnostic value of electrogastrogram(EGG) and gastroscopy in children′s gastrosis diagnosis.Methods A total of 136 children were checked with gastroscopy and EGG during the same period,then compared the diagnostic accordance rate with 2 ways,and analyzed the characteristics of EGG.Results EGG showed certain characteristics in different gastrosis.Diagnosis of EGG in the group of functional illness was consistence with gastroscopy at 95.8%;others were less than 40%.Conclusion EGG can be used as a method of special value to diagnose children′s functional gastrosis and a screening means in general gastrosis.

Objective To study the protective function of resveratrol on radiation-induced small intestine injury and lethal effect in mice.Methods Mice were randomly divided into three groups:irradiation (IR) control,IR only,and IR + resveratrol.15 mice each group were irradiated on abdomen with 7.2 Gy γ-rays for cell lethal assay and 8 mice each group were irradiated with 6.5 Gy for small intestine injury assay.For the IR + resveratrol group,the mouse was given resveratrol by intragastric administration 24 h before irradiation and then was fed with resveratrol daily for 5 days.The control and IR alone groups were fed with placebo.After 30 days of IR,mouse survival rate was detected.For small intestine injury experiments,24 h after IR,the mice were terminated and the small intestines were treated with HE and immunohistochemical staining.Results Compared with the irradiation group,resveratrol increased mouse survival by 33.3％,decreased apoptosis in intestinal crypt cells (t =17.35,P ＜ 0.05),and increased Ki67 expression (t =13.62,P ＜ 0.05).Conclusion Resveratrol could protect small intestine injury from ionizing irradiation.

Objective To investigate MELD and Child-Pugh in the patients with decompensated liver cirrhosis.Methods 41 cases of death and 71 survivors were graded with MELD and Child-Pugh and compared.Results The deaths' MELD and Child-Pugh score was (17.93?8.22 )and (10.07?1.84),the survivors' was (11.18?6.54 ) and (8.04?2.09)(P=0.000).Among the deaths and survivors,MELD≤9 was 14.63% and 42.25%(P =0.003),MELD 20-29 was 26.83% and 8.45%(P=0.009),Child A was 21.95% and 56.34%(P=0.000),Child C was 29.27% and 5.63%(P=0.001).Conclusion The deaths' MELD and Child-Pugh score is higher than the survivors'.The MELD score can act as a disease severity and prognosis index for patients with decompensated liver cirrhosis.

Objective To evaluate results of double eyelid operations with different incisions.Methods 100 patientswere selected randomly from out-patients that accepted double eyelid operation.Half of them were objected to double eyelid operation through a palpebral marginal incision.Incision was designed along the palpebral margin,close to boots of eyelashes.Most of the subcutaneous tissues was cut and removed,and then dermis and tarsal plate were fixed with 5 stitches of suture.About 1-3 mm wide of skin along superior margin was removed reasonably.In another 50 cases.double eyelid operation was performed with conventional incision.Incision was designed 6-8 mm far from the palpebral margin.Most of the subcutaneous tissues was removed.and then dermis and tarsal plate were fixed with 5 stitches of suture.Results Postoperative results were evaluated 5 days and 1 month after operation respectively.Postoperative double eyelid shapes were all satisfled in two groups.Swollen eyedids and scar were more inconspicuous in the cases with the palpebral-marginal incision without impairment on eyelashes.Conclusion Compared with double eyelid operation with conventional incision,blepharoplasty with palpebral margin incision has the same results but with lighter impairment,milder hydropsia and more inconspicuous scar.The key point of this procedure is the fixation of dermis and tarsal plate,keeping a good radian of double eyelid line.

Objective To explore the bacterial flora distribution characteristics and drug resistance of pus bacterial culture in a‐cute mastitis and to analyze thechange trend of drug resistance spectrum to provide a evidence‐based basis for the rational use of an‐timicrobial agents in clinic .Methods The pus collected from 207 cases of acute mastitis was conducted the bacterial culture .The bacterial identification and antibacterial susceptibility test were performed by adopting the manual experiment combined with the DL‐96 system .Partial drug susceptibility test was performed by combining with the K‐B method .Results Among 207 specimens , 82 strains of pathogenic bacteria were detected with the detection rate of 39 .6% ,including 51 strains (62 .2% ) of staphylococcus aureus ,7 strains (8 .5% ) of pseudomonas aeruginosa ,4 strains (4 .9% ) of staphylococcus intermedius ,4 strains (4 .9% ) of staphy‐lococcus epidermis ,3 strains (3 .7% ) of acid‐producing klebsiella bacteria and each 1 strain of staphylococcus hemolyticus and other 13 kinds of bacterium .The resistance rates of staphylococcus aureus to azithromycin ,erythromycin and clarithromycin were 92 .2% ,84 .3% and 84 .3% respectively ,indicating that macrolides drugs had a higher overall drug resistance rate and were not suitable for selection and use;the resistance rates of moxifloxacin and ciprofloxacin were 3 .9% and 4 .1% respectively ,the MRSA detection rate was 27 .5% .The resistance rates of Pseudomonas aeruginosa to ticarcillin/clavulanic acid was 85 .7% ;the drug resitance rate of cefoperazone was 83 .3% ;which of gentamycin and amikacin was 71 .4% ;which of aztreonam was 14 .3% ;which of ceftazidime was 28 .6% and which of meropenem was 28 .6% .Conclusion The majority of detected bacteria in pus from the pa‐tients with acute mastitis are Staphylococcus aureus ,followed by pseudomonas aeruginosa ,which is different from that reported by other literatures ,showing the bacterial distribution has regional difference .Staphylococcus aureus has high resistance rate to macrol‐ides antibacterial drugs ,but is highly sensitive to ciprofloxacin and moxifloxacin;Pseudomonas aeruginosa has higher resistant rate to ticarcillin/clavulanic and cefoperazone ,but it is highly sensitive to aztreonam ,ceftazidime and meropenem .Empirical medication should be comprehensively considered by combining with drug resistance spectrum of Staphylococcus aureus and Pseudomonas aeruginosa ,and the sensitive drugs should be selected according to the drug susceptibility results after the antimicrobial susceptibili‐ty test for conducting the targeted medication .

AIM:To determine whether acellular porcine cornea stroma (APCS) could support the growth of the rabbit corneal cells in vitro.METHODS: APCS was prepared. The rabbit's corneal epithelium and stromal cells were cultured and seeded on, APCS in vitro.The observation of phase contrast photograph and histological examination were performed.RESULTS: Histological examination showed the epithe- lium grew on the scaffold of APCS in 2-3 layers at 10th day. The stromal cells adhered to the surface of the scaffold after 24 hours and invaded into the interlaminar of the material at 5th day.CONCLUSION: These results indicate that APCS can support the growth and proliferation of the corneal epithelium and stromal cells in vitro.
