OBJECTIVETo explore the effect of reduction and fixation with multi-Kirschner wires for treatment of Lisfranc fracture-dislocations.

METHODSThere were 49 patients (37 male and 12 female aged from 20 to 28 years old) involved in the study. According to the Myserson damage typing, type A in 12 cases, B1 in 3, B2 in 28, C1 in 4 and C2 in 2. Kirschner wires were applied to fix and reconstruct the three-column in three directions according to the structural characteristic of midfoot. Reconstruction of three-column needed not only to reduce and to fix every single column, but also to establish union of the columns.

RESULTSAccording to the evaluation of AOFAS for midfoot, 14 cases were excellent (90 to100), 22 cases good (80 to 89), 8 cases fair (70 to 79) and 5 cases poor (60 to 69), with an average score of 84.200+/-9.663.

CONCLUSIONThe diagnosis and treatment of Lisfranc fracture-dislocations should comply with the theory of three-column reconstruction of foot arch, which can achieve the static balance of biomechanics and provide a stable environment for healing of fracture and soft tissue. Reduction and fixation with multi-Kirschner wires is an effective treatment method for Lisfranc fracture-dislocations.

OBJECTIVETo evaluate therapeutic effect of the needle-knife closed solution combined with minor adjusting of spine for treatment of neck-shoulder syndrome.

METHODSFrom April 2010 to August 2011,120 patients with neck-shoulder syndrome were treated with the needle-knife closed solution combined with minor adjusting of spine, and included 45 males and 75 females and aged from 40 to 68 years old. The disease course was from 3 days to 10 years. After the operation, all patients taken the medicine of activating blood circulation herbs. At the 3rd, 7th, 10th day after operation, spinal rotation massage was performed on these patients. After the healing of the needle points, traditional Chinese medicine herb fumigation was applied on the needle points, and the patients were directed to do the cervical spine exercise. Therapeutic effect of the patients was evaluated by the neck disability index (NDI).

RESULTSAll patients were followed up after 3 weeks' treatment. The pain of neck-shoulder was relieved, and the range of motion was improved,the NDI score lowered from 49.30 +/- 1.35 before treatment to 10.15 +/- 1.18 at 3 weeks after treatment (t = 2.116, P < 0.05).

CONCLUSIONThe needle-knife closed solution combined with minor adjusting of spine for the treatment of neck-shoulder syndrome can relieve the pain in the neck-shoulder and improved the motion of the neck. The key for the effect is accurate location before operation, sufficient adhesion solution during the operation and spinal minor adjusting after operation.

Objective To investigate kupffer cells (KCs) expressing indoleamine 2,3-dioxygenase(IDO)in the inhibition of allogeneic T-cell proliferation in vitro. Methods Real-time PCR was used to investigate the expression of IDO mRNA and FasL mRNA in KCs pretreated with or without IFNγ. High performance liquid chromatography was used to analyze the catabolism of tryptophan by IDO from KCs. Allogeneic T-cell response was used to confirm the inhibition of KCs in vitro. The proliferation of lymphocytes was detected using [3 H] thymidine incorporation. Cell cycle and lymphocyte apoptosis were evaluated by flow cytometric assay. Results Real-time PCR revealed IDO mRNA and FasL mRNA expression in KCs pretreated with IFN-γ. IDO catabolic effect was confirmed by a decrease in tryptophan and increase in kynurenine concentration. KCs expressing IDO and FasL from BABL/c mice acquire the ability to suppress the proliferation of T-cells from C57BL/6, which could be blocked by the addition of 1-methyl-tryptophan and anti-FasL antibody. The co-cultured T-cells with KCs expressing IDO and FasL could induce allogeneic T-cell apoptosis and exhibited cell-cycle arrest in G1. Conclusion In addition to the Fas/FasL pathway, IDO may also play an important role in KCs to inhibit allogeneic T-cell proliferation in vitro.

Objective To evaluate the clinical effect of popliteal artery perforator-based sural neurovascular flap for repairing soft tissue defects in middle and distal upper leg.Methods Between December,2011 to September,2015,18 cases with skin soft tissue defects on the middle and distal upper leg were treated with popliteal artery perforator-based sural neurovascular flap,in which 12 cases were males,and 6 cases were females.The age was from 24 to 55 years,with the average age of 35.9 years.The size of tissue defects ranged from 3.0 cm × 3.0 cm to 7.0 cm × 9.0 cm.Results All flaps survived completely in 18 cases,1 case of marginal infection heated after dressing,and the rest cases in Ⅰ healing.The outline and function of survived flap were satisfactory during 3-16 months follow-up,with two-point discrimination of 4.0-10.0 mm.Conclusion The anterograde sural neurovascular flap based on the popliteal artery perforator provides a practical option for covering tissue defects in middle and distal upper leg.This flap is characteristiced by reliable blood supply without sacrificing main vesses,good contour and texture,in addition,the operation is easy of handling.

Background Epidemiological investigation in human has been conclusive. In postmenopausal women,the incidence of cataract is higher than men at the same age. In addition,hormone replacement therapy may protect against the development of cataract. However,this role of androgen is not clear. Objective This study was to explore the effects of estrogen and androgen on anti-oxidative ability of lens after ovariectomy. Methods Fifty-six three-month-old clean female Wistar rats were randomly divided into normal control group,sham operation group, castration group,estrogen eyedrops group;estrogen injection group;androgen eyedrops group;androgen injection group and 8 rats for each. Ovariectomy was performed in the rats of castration group and gonadal hormone application group, and estradiol benzoate solution or testosterone propionate solution were utilized topically or systemly in 5 months after ovariectomy for 6 weeks respectively. Only abdominal cut was curried out in sham operation group. The lenses of rats were examined weekly under the slit lamp. The serum estrogen and androgen levels of rats were detected before,after operation and 6 weeks following the administration of gonadal hormone. The contents of superoxide dismutase( SOD) , glutathione( GSH) ,malondialdehyde( MDA) and water-soluble protein ( WSP) in rat lens homogenate were detected at the end of the experiment. Utilization of animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission. Results No opacity of lenses was found during the experiment duration in various groups. The serum estradiol levels of rats in sham group were insignificantly different from normal groups in various time points( P>0. 05). The evident decline of serum estradiol was detected in the rats of castration group and gonadal hormone application groups compared with sham group in 5 months after operation( all P<0. 01). However,at the sixth weeks after the system use of estradiol or testosterone,the serum estradiol levels were significantly higher than the castration group and topical application groups of gonadal hormone(P<0. 01). The contents of SOD,GSH and WSP in lenses were considerably increased,but the MDA level in lenses was decreased after system use of estrogen ( P<0. 01). The activity of SOD and GSH were lower after system use of testosterone in comparison with castration rats ( P < 0. 05 ). Conclusion Estrogen can protect lens against oxidation damage. However, androgen, to a certain extent, may contribute to the development of oxidative damage in OVX female rats.

Objective To study the reasons of natural death of Oncomelania hupensis snails by comparing the differences of the indicator days covered with water DCW in snail marshland and non?snail marshland around the build of Three Gorges Dam in Eastern Dongting Lake areas. Methods Two marshlands were selected one was a non?snail marshland Qianliang Lake and another was a snail marshland Junshan Park . The measuring points were set through the mechanical sampling. The snails and elevation of the points were surveyed and the data of the water levels from the hydrological station were collected and then DCWs were calculated. Results From 1995 to 2013 DCWs of the marshland of natural death of snails were all more than that of the snail marshland P<0.01 . In Qianliang Lake marshland the difference between DCW before natural death and DCW from natural death until the dam was not significant P=0.23 while DCWs of the two stages both were more than that after the dam P1=0.045 P2=0.002 . Before the build of the dam DCW of the Qianliang Lake marshland of natural death of snails was more than that after the build of the dam P=0.013 and there was the same situation in Junshan Park marshland P=0.005 . The relationship between snail density and DCW was not significant in Junshan Park marshland rs=0.008 P=0.914 and the reference range of DCW of all the measuring points was 76-251 days. Conclusion In the eastern Dongting Lake district the build of Three Gorges Dam and DCW may be not the direct factors affecting the natural death of snails and the latter may change the distribution of snails.

Objective To study the reasons of natural death of Oncomelania hupensis snails in marshland by comparing the differences of environmental factors between snail marshland and non-snail marshland in East Dongting Lake schistosomiasis en-demic areas. Methods Two adjoining marshlands were selected,one was a snail marshland and another was a non-snail marsh-land. The measuring points were set by grid of“20m × 20m”. The soil moisture,elevation,soil pH and temperature of the points were measured,and the snails of the points were surveyed. Results The elevation,soil pH and temperature of the snail natural death marshland were all lower than those of the snail marshland(P<0.01). The soil moisture,elevation,soil pH and temperature of different snail densities in the snail marshland were different(P<0.05). The soil moisture of the non-snail group was higher than that of other four groups(P<0.01)and the soil moisture of the group with 0-11 snails per frame was lower than that of other four groups(P<0.01). The elevation of the group with 0-11 snails per frame was lower than that of the group with 24-39 snails per frame and the group with more than 39 snails per frame(P<0.05). The soil pH of the group without snails was higher than that of other four groups(P<0.01)and the soil temperature of the group with 0-11 snails per frame was lower than that of the group with 24-39 snails per frame. The differences of soil moisture and elevation of different death snail densities were not significant, while the differences of soil pH and temperature were significant. The soil pH of the non-snail died group was higher than that of the 2-died,3-died and more than 3-died groups(P<0.05). The soil temperature of the non-snail died group was higher than that of other four groups(P<0.05). Conclusion The elevation,soil pH and soil temperature within the range of the research may be the factors affecting the snail natural death and the soil moisture,elevation,soil pH and soil temperature may be the factors affect-ing the distribution of snails.
