Purpose To explore the ultrasonic features of tibial nerve (TN) in tarsal tunnel of type 2 diabetes mellitus patients with diabetic peripheral neuropathy (DPN), and to provide the basis for assessment and treatment. Materials and Methods Fifty-four patients with type 2 diabetes mellitus were divided into the DPN group including 31 patients with diabetic periphreal neuropathy and the non-DPN group including 23 patients without diabetic periphreal neuropathy, 22 cases of non diabetic patients were also enrolled as the control group, all the subjects underwent medial tibial nerve ultrasound examination, and the ultrasonic features of tibial nerve (including morphological parameters:left-right diameter, anterior-posterior diameter, thickness sectional area and color Doppler lfow signals) were compared. Results Left-right diameter and anterior-posterior diameter of DPN group were larger than those of non-DPN group and the control group (P<0.01). Ultrasonic features of tibial nerve of DPN group included nerve bundle hypoechoic, vaguedscreen clothstructure, thickening and fuzzy of neural membrane, and the unclear boundaries to adjacent tissue. There was no statistically signiifcant difference in color Doppler signal of TN (P>0.05) among the DPN group, non-DPN group and the control group. Conclusion There are some characteristics features of tibial nerve in tarsal tunnel of type 2 diabetes mellitus patients with DPN, ultrasound can be used to evaluate the morphology of TN in type 2 diabetes mellitus patients with DPN and to provide morphological basis for evaluation and treatment selection.

Objective To investigate the effects of long-and mid-term indwelling AO clavicular hook plate (CHP) on the shoulder function following surgery for acromioclavicular dislocation(from grade Ⅲ to grade Ⅴ by Rockwood's classification).Methods A retrospective study was done of 95 patients with acromioclavicular dislocation who had been fixed with AO CHP from December 2002 to May 2011.They were 80 men and 15 women,aged from 20 to 63 years (average,45.0 years).By the Rockwood's classification,there were 40 cases of type Ⅲ,35 ones of type Ⅳ and 20 ones of type Ⅴ.Time from injury to surgery ranged from 2 to 7 days (average,4.6 days).The CHP was indwelling in 70 patients but removed in 25 patients from 12 to 23 mouths post-surgery (average,16.5 months).The University of California (UCLA) shoulder scoring system was used to compare the shoulder functions between those with an indwelling CHP and those without,as well as between the healthy and affected shoulders among those with an indwelling plate.Results The follow-up time for all the 95 cases ranged from 7.5 months to 9 years,with an average of 38 months.Of those with an indwelling CHP,subacromial bone erosion occurred in 45,internal implant failure in 3,impingement in 13,screw loosening in 2 and frozen shoulder in 5,giving a complication rate of 97.1％ (68/70).Of those without an indwelling CHP,subacromial bone erosion occurred in 3 and no redislocation was found in this group,giving a complication rate of 12.0％ (3/25).The UCLA score for the affected shoulder among those with an indwelling CHP(27.0 ± 11.0 points) was lower than that for the healthy one (34.0 ± 1.0 points) and lower than that for the affected shoulder among those without an indwelling CHP(32.0 ± 6.5 points).Conclusion Long-and mid-term indwelling AO CHP can have a significant adverse impact on shoulder function,leading to a very high rate of postoperative complications.

Objective To investigate the role of epithelial cell apoptosis in the stress-related changes of intestinal mucosa barrier following traumatic brain injury. Methods Sixty-four health male Wistar rats were divided randomly into two groups: (1) traumatic brain injury model group (n =32) ,in which rats suffered from traumatic brain injury by Feeney's method; (2) control group ( n = 32) , rats suffered from sham operation. Each group were divided into four subgroups according 6 h, 12 h,24 h, and 48 h after operation ( n = 8, for each subgroup ). Ileum tissue were taken to observed the damage of the intestinal mucosa under microscope and electronmicroscope. The early apoptosis rate of intestinal mucosal cells were analyzed with Annexin Ⅴ-PI double stained and detected by flow cytometry. Results The intestinal mucosa were damaged and the intercellular space of intestinal mucosal were found increased in traumatic brain injury group. The early apoptosis rate of intestinal mucosal epithelial cells was significant increased in traumatic brain injury group than that in control group [6 h: (13.5 ±3.7)% vs (6.1 ± 1.7)%, P＜0.05; 12 h:(66.1±6.0)% vs (5.2±1.1)%, P＜0.05; 24 h:(39.8±4.8)% vs (8.4±2.6)%, P＜0.05;48 h: (7.5 ±1.3)% vs (6.6 ±0.5)%]. Conclusion The increased early apoptosis rate of intestinal mucosal epithelial cells might contribute to the stress-damage of the intestinal mucosa barrier in early stage of traumatic brain injury.

Objective To study the antibacterial performance of the fabric treated with siliconequaternary ammonium microemulsion.Methods Escherichia coli,Staphylococcus aureus and Candida albicans were used as the test bacteria and the method of bacteriostasis circle,vibration flask were used to test the effects of the antibacterial agent qualitatively and quantitatively.Results The lowest bacteriostasis concentration for siliconequaternary ammonium microemulsion was 2%,the bacteriostasis effect on staphylococcus was superior to that on E.coli and it had a good bacteriostasis effect on the yeast.Pure cotton bacteriostasis effect was most noticeable in its antibacterial reorganization and it reached 92.34% of the bacteriostasis rate after washed for 30 times,and the bacteriostasis rate for the treated fabric could still keep 99.96% after 6 months of preservation.Conclusion The fabric reorganized with the siliconequaternary ammonium microemulsion has a good capacity of bacteriostasis and washes well in antibacterial performance.

Objective To study the effect of human Slitrk1 gene on proliferation and differentiation of PC12 cells. Methods The CDS sequence of Slitrk1 was amplified by PCR, and then cloned into pcDNA4 vector. The recombinant plasmid pcDNA4/Slitrk1 were transfected into rat PC12 cells by lipofectamine. The stable expression cell clones were screened by RT-PCR. MTT method was used to detect the proliferation rate of PC12 cells. The morphologic changes in PC12 cells were observed microscopically. Results The stable cell lines expressing pcDNA4 (pcDNA4/PC12) and pcDNA4/Slitrk1 (ST1/PC12) were established. Compared to pcDNA4/PC12 cells, the growth rate of ST1/PC12 cells was decreased. In addition, pcDNA4/PC12 cells tend to grow as well as the normal PC12 cells. However, most of the ST1/PC12 cells adhered to the plate with one or two neurites. Conclusion Over-expression of human Slitrk1 gene inhibited the proliferation of PC12 cells and promoted the outgrowth of neurites. It is suggested that human Slitrk1 gene may be involved in differentiation of PC12 cells.
