BACKGROUND:Removing the posterior ligamentous complexes during posterior lumbar interbody fusion (PLIF) may influence motion and load bearing characteristics of the adjacent segments,contributing to the postoperative instability at the adjacent segment,which is one of the important factors for adjacent segment degeneration.OBJECTIVE:To evaluate the clinical effectiveness of the PLIF plus screw implantation preserving posterior ligamentous complexes under microscope.METHODS:Thirty-six patients with single-level lumbar degenerative disease were enrolled,which were allotted to experimental (n=17) and control (n=1 9) groups,followed by treated with PLIF plus screw implantation preserving posterior ligamentous complexes,and traditional PLIF plus screw implnatation,respectively.The Visual Analogue Scale scores and Oswestry Dysfunction Index at baseline and postoperative 3 months were assessed.The adjacent segment degeneration was observed through radiology during follow-up.RESULTS AND CONCLUSION:The Visual Analogue Scale and Oswestry Dysfunction Index scores in the two groups were significantly lower than those before treatment (P ＜ 0.01),and the postoperative scores in the experimental group were significantly lower than those in the control group (P ＜ 0.01).The adjacent segment degeneration occurred in two cases in the experimental group and 8 cases in the control group during follow-up.Radiology revealed that the internal fixative was stable,none of screw loosening,rupture or pullout.These results suggest that PLIF plus screw implantation with posterior ligamentous complexes can effectively relieve the pain and dysfunction in the lumbar degenerative patients,and reduce the incidence of adjacent segment degeneration.

To retrospectively analyze the clinical data of 42 patients at our department with bulbar myasthenia gravis.They underwent video-assisted thoracoscopic extended thymectomy (VATET) from May 2003 to August 2010.Another 42 patients treated with medications alone were selected as controls.Compared with the control group (4.32 ± 0.23),postoperative dysphagia scores improved significantly in patients undergoing VATET(9.21 ±0.41).And so did the dysphagia assessment classification (P ＜0.05).Thus VATET could effectively and definitely relieve dysphagia in patients with bulbar myasthenia gravis.

Objective To evaluate the clinical experience and skills of laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection in order to spread and popularize this kind of operation.MethodsUnder general anesthesia,32 patients(42 sides)with inguinal hernias were repaired by laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a dissection balloon from August 2005 to December 2007.ResultsAll of operations were successfully performed.The operative time was 60-120 minutes,the blood loss was 20-60 ml,and the length of postoperative hospitalization was 3 days.All cases were followed up for 8 to 18 months and found no recurrence.ConclusionLaparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection is feasible,reliable and effective,offering a low recurrence rate,while its price is higher than tension-free herniorrhaphy by traditional method.

The gene nhaA encodes functional protein that may play an important role in salt tolerance of Escherichia coli In order to study bacteria salt tolerance, a pair of primers were designed according to public nhaA sequence and was used to amplify 1 1kb DNA fragment with PCR The nhaA gene from E coli DH5?was cloned into a T vector and sequence analyses reveal that the cloned fragment contains entire nhaA gene coding region To apply the method of homology analysis,the result shows that many kinds of bacterium have nhaA gene, such as E coli K12, E coli O157:H7, Salmonella typhimurium and Salmonella enterica , et al This analysis suggests that nhaA gene lie generally in bacterial; and it has intimate relation with salt tolerance of E coli that may be of great importance in improvement of the salt tolerance of plant

Background Proliferation of the human Tenon capsule fibroblasts(HTFs) is a main cause of failure of filtering surgery.To search the drug of inhibiting the growth of the HTFs is essential for the improvement of successful rate of filtering surgery.Objective The aim of this study was to investigate the inhibitory effect of apigenin on HTFs and its mechanism.Methods Human Tenon capsular tissue was obtained during the strabismus correction surgery.HTFs was primarily cultured using explant method and identified using vimentin by immunochemistry.The 3-5 generation of cells were incubated to 96-well plate.Apigenin of 0,20,40,80,160 μmol/L was added into the medium,respectively,for 24,48,72 hours,and the proliferation of HTFs was detected by sulfonyl chloride (SRB) at the wavelength of 560 nm (A560).Bromodeoxyuridine (BrdU) of 10 μg/L was added to culture the cells for 48 hours to calculate the labeling rate of BrdU.The morphology of the cells was observed using Hoechst 33258 staining,and apoptosis and cells cycle were evaluated by flow cytometry.Results Cultured cells grew well with the positive response for vimentin,showing the green fluorescence in cytoplasm.SRB assay showed that the A560 value was gradually declined with the increase of the dosage of apigenin and prolong of time (Fgroup =480.306,P =0.000 ; Ftime =555.144,P =0.000).The labeling rate after 0,40,80 μmol/L apigenin acted for 48 hours was (87.860 ±0.632)％,(61.520±4.306)％ and (23.480±4.472)％,showing a significant difference among the three groups (F =299.347,P =0.000).The labeling rate of HTFs for BrdU was significantly decreased in the 40 and 80 μmol/L apigenin groups compared with the 0 μmol/L apigenin group (P＜0.05).Hoechse 33258 staining found that the number of the HTFs was gradually decreased and the cell number of karyopyknosis and nuclear deformation was increased with the increase of apigenin dosage.Percentage of cells in G0/G1 phase were raised and that in S and G2/M phase were declined in the higher dosage apigenin group,with a significant difference among the different groups (FG0/G1 =58.621,P=0.000;Fs =32.357,P=0.001 ;FG2/M =83.998,P=0.000).In the 72nd hour after acted by 0,40,80,160 μmol/L apigenin,the apoptosis rate of HTFs was (4.77±0.21) ％,(13.24±1.35)％,(18.33±1.86) ％,(31.58 ± 2.77) ％,respectively,with a statistically significant difference among the four groups (F =204.791,P＜0.05).Conclusions Apigenin restrains the growth of HTFs by evoking G0/G1 cell cycle arrest and inducing apoptosis in a dosage-and time-dependent manner.

AIM: To analyze the value of 24 - hour intraocular pressure ( IOP) monitoring in suspected glaucoma patients. METHODS: Totally 48 suspected glaucoma (96 eyes) were selected for 24 - hour IOP monitoring by using Accupen tonometer (24 - 3000) and non - contact tonometer (NCT, CT-80A) from 9 30 to 7 30 next day (once in 2h). During 07 30 to 21 30, patients were measured in sitting position,while during 23 30 to 05 30 in both sitting and supine position. RESULTS:A morning peak of IOP was shown at 7 30 in traditional position by using two measures with 22.05士3 608mmHg of NCT and 19.79士4.147mmHg of Accupen tonometer. The peak IOP in habitual position appeared in 5 30 with 21.64士4.814mmHg. The lowest IOP occurred in both position at 21 30 with 15. 73士3. 649mmHg. Both positions showed IOP trend of going up at night and then declining in the morning. CONCLUSION: The peak IOP in suspected glaucoma occurs mostly at early morning. Supine IOP of sleeping time is higher than that of sitting position.

OBJECTIVEIn order to get the method for improving the salt resistance of Lycium ruthenium seeds and seedlings under NaCl stress, the seed germination and physiological characteristics of L. ruthenium seedlings was studied.

METHODSeveral physiological indexes of L. ruthenium seeds under NaCl stress, such as the germination rate (Gr), germination vigor (Gv), germination index (Gi), vigor index (Vi), and relative salt damage rate were measured. Other indexes of the seedlings like relative water contents (RWC) , chlorophyll contents, soluble protein contents, electrolyte leakage, the contents of malondialdehyde (MDA), and peroxidase (POD) were also measured.

RESULTNaCl at lower concentration could promote the seed germination but inhibit the seed germination at higher concentration. After the treatment by CaCl2 at the different concentrations, all germination indexes were increased. With the increase of salt concentration, the relative water contents and the contents of chlorophyll were decreased, the content of MDA and electrolyte leakage were increased. The change trend of POD activity showed the first increase and then decrease with the increase of salt concentration, which was similar to that of the soluble protein. After the treatment by CaCl2, relative water contents, chlorophyll and POD activities were decreased more slowly, and also electrolyte leakage and MDA contents increased slowly.

CONCLUSIONThe CaCl2 could significantly alleviate the damages to the seeds and seedlings of L. ruthenium under NaCl stress, and promote the salt resistance to the seeds and seedlings of L. ruthenium.
