The spceics identification by the hemoglobin band patterns in blood stains using isoelectric focusing with amphotine made in China is reported. Forty different sorts of bloodstain from human and animals were studied. Although the ability of species identification of hemogolbin band patterns in blood stains is lower than those in hemolysates, but the indentification of humen blood stain and the blood stains from most different spcies of animads were achieved. With the exception blood stain indintification between human adult foetus and monkey as well as between five groups in classes of bird and fish Human adult blood stain could be distinguished much easily from animal's blood stains but not from human foetus ,if the blood stairis were pretreated with PCMB. It is concluded that the species indentification of blood staine using isoelectice focusing with ampholinemade in china is possible.

BACKGROUND :Although the conventional 20 G pars plana vitrectomy can improve the prognosis of vitreous-retina diseases,but it would also cause serious operation related injury and much complications.OBJECTIVE:To evaluate the practicability and safety of 25-gauge transconjunctival sutureless vitrectomy system (TSV25G) in the macular surgery, so as to elicit the preliminary clinical experience of mimimally invasive vitrectomy system.DESIGN:Case analysisSETTING: Department of Ophthalmology, General Hospital of Chinese People's Armed Police Force; Department of Ophthalmology, Beijing Sino Japen Friendship Hospital; Department of Ophthalmology and Visual Science, Chinese University of Hong Kong; Department of Ophthalmology,Prince of Wales Hospital, Hong Kong PARTICIPANTS: From July 2003 to July 2004, 16 patients with macular diseases were admitted to the Department of Ophthalmology in the General Hospital of Chinese People's Armed Police Force and taken as subjects (n=16), they were confirmed as epiretinal membrane in 9 eyes, idiopathic macular hole in 3 eyes, traumatic macular hole in 2 eyes and vitreo-macu lar tractional syndrome in 2 eyes. The course of disease ranged from 3 to 36 months with eyesight varied between 0.06 and 0.4.METHODS: 16 eyes underwent preoperative ophthalmic evaluation in cluding visual acuity measurement, Amsler chart test, slit lamp microscopy,.indirect ophthalmoscopy tonometry and optical coherence tomography (OCT). For the macular hole patients OCT was performed. 25-gauge Transconjunctival Sutureless Vitrectomy System (TSV25G) was used to carry on minimally invasive surgery under anesthesia state, the surgical parameter was set as: high speed cutter with rate of 1500 cuts per minute,BSS bottle was hang at height of 40-50 cm, the maximum aspiration of TSV25G was 550 mm Hg with the intraocular pressure remained at around 29-35 mmHg during the operation. Three-beveled trocar were used to make three-transeonjunctival incision on sclera of about 0.5 mm long respectively in the infratemporal, superotemporal, and supraotemporal quan drants, meanwhile a transconjunctival cannula was placed. One end of the infusion tube was inserted into the infratemporal cannula to establish infusion with the other two cannulas used for the intraocular operation with 25-gauge vitreous cutter and other instruments, such as vitreoectomy and membrane dislocation. The surgery was terminated by removing the cannula except for ceaseless leak, the conjunctival and scleral incision were not sutured. Patients received follow-up examination for 1-12 months postoperatively.MAIN OUTCOME MEASURES:①The operative time and the time for the establishment of three access. ② Changes of intraocular pressure after operation. ③ The effusion from the puncture after the intraocular perfor mance. ④ The postoperative vision, operative complication and the sealing of the holes.RESULTS:All of the 16 patients completed the vitrectomy; and entered the data analysis.①16 patients complete the vitrectomy with the operative time of 28-56 minutes (the mean of 37 minutes). The average time for the establishment of three access and closing was 84 s and 32 s respectively.②The average preoperative intraocular pressure was 16.4 mm Hg,comparing with 13.5,15.5,17.9 mm Hg at postoperative 1 day, 1 w and 1 m. ③Water leakage were found in 4 wounds of three patients after operation, 3 wounds were sealed after injecting 1-2 mL disinfected air into the eyes, the other one sutured with 6-0 absorbable suture. ④The mean time of inpatients were 5 days postoperatively. The visual acuity improved in 14 patients by the average of three lines, amongst which visual acuity was found improved to above 0.8 in 5 patients and the visual distortion disappeared in 8 eyes and attenuated in 3 eyes. But still there were 2 cases without improvement.No surgical complications were noted and macular hole gained clinical sealing in totally 5 eyes.CONCLUSION: TSV25G system can simplify the surgical procedure with many other advantages such as decreasing the operation related injury and complications, as well as shortening operative time, which benefits the rapid rehabilitation.

Objective To investigate the value of the application of the fresh first morning midstream urine in cytological study of bladder cancer patients. Methods The results of the fresh first and second morning midstream urine cytological studies for 52 bladder cancer patients were analyzed.Continual three urine samples and single urine sample were treated as study objects respectively. The positive rates in different tumor stages and grades were evaluated. Results The positive rate of overall 52 patients was 78. 8 % (41/52) in fresh first morning midstream urine and 80. 8% ( 42 / 52) in the fresh second morning midstream urine. While in 156 single urine samples, the positive percentages were 56.4%(88/156) and 60. 9% (95/156). The positive rates of the fresh first and second morning midstream urine were 69.7% (23/33) and 72.7% (24/33) respectively in grade 1- 2 patients, and 44.4 % (44/99) and 48. 5 % (48/99) in 99 single urine samples. The positive rates of 42 non-muscle invasive bladder cancer patients were 73. 8% (31/42) and 76.2% (32/42) in the fresh first and second morning midstream urine, while in 126 single urine samples, the positive rates were 54.8% (69/126)and 57.1% (72/126). There were no significant differences between positive rate of the fresh first and second morning midstream urine in diagnosis of bladder cancer, low grade bladder cancer and nonmuscle invasive bladder cancer. Conclusion The fresh first morning midstream urine can be used for urine cytological study in the diagnosis of bladder cancer, even in the diagnosis of low stage and low grade bladder cancer.

Objective To investigate the value of MR diffusion tensor imaging (DTI) quantitative parameters in evaluating the injury of the tibial nerve and the common peroneal nerve in patients with Guillain-Barre syndrome(GBS). Methods Sixteen healthy volunteers and sixteen patients with GBS underwent DTI examination of the tibial nerve and the common peroneal nerve. The denervation of skeletal muscles controlled by the tibial nerve and the common peroneal nerve was observed. The apparent diffusion coefficient (ADC) value, fractional anisotropy (FA) value, axial diffusivity (AD) value and radial diffusivity (RD) value were measured respectively,and diffusion tensor tractography (DTT) of the tibial nerve and the common peroneal nerve was performed. Between-groups comparison was made with the independent sample t test and receiver-operating characteristic (ROC) analysis was used to evaluate the diagnostic efficacy of the parameters. Results (1)The MR features of denervated skeletal muscles comprehend hyperintensity on T2WI SPAIR sequence and the instinct boundary, muscle atrophy occationally. (2)Compared with the healthy volunteer group, the ADC value of the tibial nerve and the common peroneal nerve of GBS group was increased and the FA value, AD value, RD value were decreased, and there was significant difference between the ADC value, FA value, AD value and RD value of GBS and volunteer groups respectively(P<0.05). The area under the curve (AUC) of FA value was higher than that of the corresponding ADC value in the tibial nerve and the common peroneal nerve. (3)DTT showed that the number of fibers decreased in patients with GBS compared to the normal volunteers. Conclusion MR can clearly show the denervated skeletal muscles controlled by the tibial nerve and the common peroneal nerve. The ADC value, FA value, AD value and RD value, the quantitative parameters of DTI, can evaluate the injury of the tibial nerve and the common peroneal nerve in patients with GBS.

At present, hepatic resection (HR) and radiofrequency ablation of (RFA) are the main radical treatment methods for small hepatocellular carcinoma (sHCC), while stereotactic body radiotherapy (SBRT) is developing rapidly and there is an increasing number of reports on the effective treatment of sHCC with SBRT. This article introduces the technical advantages, therapeutic dose, and fractionation scheme of SBRT in the treatment of sHCC, as well as the limit of normal liver tissue and the protection of surrounding organs at risk. This article also compares the efficacy of SBRT versus HR and RFA in the treatment of sHCC and briefly describes the adverse reactions of SBRT in the treatment of sHCC. Previous studies have shown that for some sHCC cases, SBRT has an equal or even better clinical effect than HR and RFA, with controllable toxicity. Therefore, SBRT is expected to become another radical treatment method for sHCC.
