Objective To investigate the proportions of the functional dyspepsia (FD) subgroups and to explore theri relationship with Helicobacter pylori (HP).Methods 186 cases with FD received questionaires about their condition and were typed according to their symptom.HP was detected through urease test,spear technique and cultivation.Results The proportion and HP-positive rate of the subgroup were 11.29%,14.24% in reflux-type dyspepsia,13.98%,46.15% in ulcer-type dyspepsin,48.39%,41.11% in dysmotility-type dyspepsia and 26.34%, 38.78% in complex dyspepsia,respectively.The total HP-positive rate of FD is 38.17%.Conclusion Dysmotility-type dyspepsia is most common.Some subgroups are overlapping with each other.There is no relationship between FD and HP.The HP-positive rate of the reflux-type dyspepsia is lower.This observation suggests that HP may have protective effects on esophagus.

Objective To evaluate the mortality and causes of injury among elderly patients with multiple injuries. Methods All the young (18 to 35 years, n=422) and elderly (60 87years, n=80) patients were evaluated with an abbreviated injury scale score (AIS) injury severity score (ISS).All patients with ISS ≥16 were selected in period 5 year (from January 1995 to January 2000) . Age, sex, mechanisms of injury, mortality, hospitalization, and intensive care treatment were analyzed. Results Traffic accident was the leading cause of injury in both young and elderly groups. Mortality in the young was lower than that in the elderly (14 2% vs 37 5%, P

Objective To investigate the feasibility of laparoscopic operations in treating large ovarian cysts.Methods A total of 38 patients with large ovarian cysts underwent laparoscopic cyst cystectomy or adnexectomy on the affected side from December 2002 to October 2005.The 2nd or 3rd trocar(usually on the tumor side)was inserted into the cyst,the fluid in which was drained with a suction unit.The cyst was then removed after being elevated toward the incision,which was extended to 20 mm.Results Large ovarian cysts in the 38 cases were all removed successfully,including cystectomy in 28 cases and adnexectomy in 10 cases respectively.No complication occurred.The follow-up period was 1-24 months(mean:10 months)for 35 cases.No abnormal findings in pelvic examination and B ultrasonography were observed.Conclusions Laparoscopic operation is a safe and feasible therapeutic method for large ovarian cysts.

Background Krüppel-like factor 6 (KLF6) is related to the physiological or pathological process,such as growth,cell differentiation,proliferation,apoptosis,angiogenesis,tissue repair,and so on.But in ophthalmology,it is less reported about the expressing level of KLF6 protein in lens epithelial cclls (LECs) or the effect of KLF6 on the proliferation of human LECs.Objective This study was to investigate whether KLF6 can inhibit proliferation of human LECs.Methods KLF6 eukaryotic expression plasmid (pEGFP-C2-KLF6) was constructed using reverse transcription PCR(RT-PCR) and identified by double enzyme digestion method and PCR.Human LECs strain (HLE-B3) was cultured and passaged using low glucose DMEM containing 10％ fetal bovine serum and then divided into 4 groups.KLE-B3 transfection reagents were added in the culture medium of all groups.In addition,no agent was used in the blank control group;only insulin-like growth factor-1 (IGF-1) was appended to the medium in only IGF-1 group ;null vector was transfected and IGF-1 was appended in the null plasmid transfection+ IGF-1 group;while pEGFP-C2-KLF6 eukaryotic expression plasmid was transfected into the cells,and simultaneously IGF-1 was added in the pEGFP-C2-KLF6 plasmid transfection+IGF-1 group.After 24 hours of intervene,water soluble tetrazolium salt-1 (WST-1) test was used to detect the growth status of the cells,and Western blot assay was used to assay the relative expressing level of KLF6 protein in the cells.In the other hand,the cells were cultured at the density of 1 ×104/piece,and 0,0.10 and 0.25 μg pEGFP-KLF6 were transfected into each piece of cells respectively,and then IGF-1 was added with a final concentration of 50 μg/L for 24 hours after cell culture.Expressions of Ki-67 protein and mRNA in the cell pieces were detected by immunocytochemistry and fluorescent semiquantitative PCR,respectively.Results The PCR product bands were consistent with KLF-6 gene in length,and the product fragments were corresponding with expectant ones via PCR and double enzyme digestion method,showing a successful construction of pEGFP-C2-KLF6 eukaryotic expression plasmid.After 24 hours of IGF-1 stimulation,the absorbance values of the cells were 0.86±0.00,2.10±0.01,2.24±0.12 and 1.06±0.02 in the blank control group,only IGF-1 group,null plasmid transfection + IGF-1 group and the pEGFP-C2-KLF6 plasmid transfection + IGF-1 group,with a significant difference among the 4 groups (F =38.322,P ＜ 0.05),and that in the pEGFP-C2-KLF6 plasmid transfection +IGF-1 group was significantly lowed in comparison with the only IGF-1 group and the null plasmid transfection+IGF-1 group (q=6.42,7.31,both at P＜0.05).Western blot assay showed that the relative expressing levels of KLF6 protein were statistically different among the four groups (F =591.858,P＜0.05),and those in the pEGFP-C2-KLF6 plasmid transfection+IGF-1 group were 1.47,2.04,3.27 folds higher than those in the blank control group,only IGF-1 group,respectively and null plssmid transfection+IGF-1 group,respectively.Immunocytochemistry revealed that the expressing intensity of Ki-67 protein was gradually weakened with the decrease of pEGFP-C2-KLF6 plasmid dose in the 0,0.10 and 0.25 μg pEGFP-C2-KLF6 plasmid transfection+IGF-1 groups.Fluorescence semiquantitative PCR results showed that the relative expression values of Ki-67 mRNA in the cells were O.15±0.08 and 0.11±0.03 in the 0.10 μg and 0.25 μg pEGFP-C2-KLF6 plasmid transfection+ IGF-1 groups,which were significantly lower than O.77± 0.12 of the 0 μg pEGFP-C2-KLF6 plasmid transfection group,with a statistically significant difference among the three groups (F =54.825,P＜0.05).Conclusions KLF-6 can effectively inhibit IGF-1-induced proliferation of human LECs,and it can be regarded as one of the regulatory factors of the proliferation of HLE-B3 cells.

Objective To observe the changes in cytokines, oxygen free radicals, acidulous production in serum and to investigate the effectiveness of monitoring metabolism of cells and the method for evaluating cell injury in patients with severe trauma. Method The detailed data of 117 patients rescued and managed carefully from May 2005 to February 2007 were assessed and stratified with ISS and APACHE Ⅱ , and the serum levels of arterial blood lactate(ABL) ,base deficit(BD) ,superoxide(SOD) ,lipid peroxide(LPO) ,TNF-α and IL-6 were measured in real-time according to the condition of the patient. Results The monitoring biomarkers obviously changed with injury severity which endangered the situation of patients after trauma (P < 0.05) , especially in the patients with ischemia , hypoxia, shock, iniection, SIRS, and MODS (P < 0.01). The persistence of extremely elevated levels of biomarkers meant the organ failure and fatality of patients after trauma, and there was a obvious differece between those cases and cases without elevation of biomarkers ( P < 0.01). Conclusions The outcome of patients after trauma is closely correlated with injury severity,infection and MODS,and the levels of biomarkers including ABL, SOD, IPO, TNF-a and IL-6 are useful indicators of outcome measure.

Objective To compare the application of two different radial artery puncture and cannulation methods in septic shock patients. Meth-ods A total of 80 septic shock patients who need emergency operation were enrolled in this study. The shock index was>1.0. The patients were randomly divided into two groups:ultrasound group(group U)and palpation group(group A),with 40 cases in each group. For the patients in group U,Sonosite S-Nerve ultrasound in the wrist was used to determine the location of the radial artery puncture. For the patients in group A ,pal-pation method was used to determine the location of the radial artery puncture. The heart rate,blood pressure,first puncture success rate,total suc-cess rate,number of punctures,puncture time and complication rate of the two groups were monitored. Results The success rate of first puncture and total success rate of group U were higher than those of group A ,the number of puncture was less than that of group A ,the puncture time was shorter than that of group A,and the incidence of complications was lower than that of group A(P<0.05). Conclusion The application of ultra-sound for radial artery puncture and catheterization in septic shock patients is accurate ,and with higher first success puncture rate and total success rate,less number of puncture,shorter puncture time,and lower incidence of complications compared with palpation method.
