OBJECTIVETo evaluate clinical results of plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot.
METHODSSeven patients (9 feet) patients with tarsometatarsal joint dislocations secondary to diabetic charcot foot were treated with plating from April 2012 to December 2014. All patients were male, and 5 cases were on the unilateral side and 2 cases were on the bilateral sides. The age of patients ranged from 45 to 52 with an average of 48 years old. The history of diabetics was from 6 to 15 years. X-ray and CT were used to evaluate fractures healing,and AOFAS was applied to estimate recovery of joint function.
RESULTSAll patients were followed up from 12 to 24 months with an average of 19 months. All incisions were healed at stage I . No infection, loosening and breakage of internal fixation, bone nonunion were found after operation. According to postoperative X-ray and CT results, the time of fracture healing ranged from 10 to 20 weeks with an average of 16 weeks. Six feet got excellent results, 2 good and 1 moderate based on AOFAS scoring.
CONCLUSIONTarsometatarsal joint dislocations secondary to diabetic charcot foot treated with plate on the metatarsal side could obtain stable fixation and got satisfied early clinical results.

To investigate the feasibility to produce crocetin in tobacco plants.The coding region of zeaxanthin cleavage dioxygenase (CSzCD) gene from Crocus sativus L. was inserted into the downstream of the cauliflower mosaic virus (CaMV) 35S promoter of a binary vector pBI121, and integrated into the genome of Nicotiana tabacum L. Twenty-one transgenic lines were identified by genomic southern blotting analysis. Western blotting and HPLC analysis of the leaf extracts of transgenic tobacco showed that crocetin was produced in CSzCD gene-transformed plants, while no crocetin was found in the untransformed tobacco.

Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

AIM: To evaluate the efficacy and safety of two different surgical techniques on congenital cataract on children.METHODS: Twenty-two children (1-3 years old) with congenital cataract were randomly divided into two groups (group A and group B). With group A (10 patients, 20 eyes), we applied 23-gauge (23G) trans corneal limbus vitrectomy system to complete lens cortex gettering, posterior capsulotomy and anterior vitrectomy;With group B (12 patients, 24 eyes), we used the phacoemulsification I/A to complete lens cortex gettering, and performed anterior vitrectomy with anterior vitreous cutting instrument. After that, the differences in intraoperative and postoperative complications between two groups were compared. RESULTS:In group A, the width of corneal limbal incision was 0.6mm, the incision was self-sealing, and the anterior chamber was stable and iris did not prolapse during the surgery. In group B, the width of corneal limbal incision was 3mm, anterior chamber was unstable and intraoperative iris prolapse occurred in 14 eyes (58%). And the incision need to be stitched up after surgery. In the postoperative follow-up of 6-24 months (an average of 14 months), we found that corneal neovascularization did not occur in group A, while in group B, corneal neovascularization occurred in four eyes (17%); Other complications, such as posterior capsular opacification,retinal detachment, glaucoma, hypotony or endophthalmitis did not occur in either group.CONCLUSION: The 23G trans corneal limbus vitrectomy system used in pediatric cataract surgery is safer and more effective than phacoemulsification I/A. It is promising in treatment of congenital cataract on children.
