The Leishmania Donovani, in bone morrow of 1 case Kala-Azar was observed with electron microscope. The results showed that the ultrastructure of the Leishmania Donovani was similar to that of other Leishmanial species, however, there were some differences in the size of parasites, microtubule intervals and numbers.

Objective To investigate the clinical and pathological characters and seize the diagnostic main points of minimal deviation adenocarcinoma of cervix to improve the accuracy of pathological diagnosis. Methods A clinic pathological review of 6 cases with minimal deviation adenocarcinoma was analyzed retrospectively. Results The main clinical symptoms were watery leucorrhagia, enlargement of the cervix with erosin and hardening. The pathological findings included hyperplasic and mild abnormality of the glands, invasion effects into the stroma could be observed in some glands and abortive glands with desmoplastic changes, or edema and inflammatory infiltration around the glands were also observed. Conclusion The detection rate of minimal deviation adenocarcinoma may increase by triple combination of clinic, cytology and histology.

This study was to retrospectively report the clinical effects of retropublic passage tension free vaginal tape(TVT)vs.transobturator tape(TVT-O)on 254 female patients with stress urinary incontinence(SUI).Our findings showed that mean operative time was significantly lower in TVT-O group than that in TVT group[(19±4)min vs.(27±6)min;P＜0.05].Perioperative complications were more commonly seen in the retropubic procedure(2.9% vs.8.8%;P＜0.01).There was no significant difference in intraoperative blood loss[(19±6)ml vs.(31±8)ml in TVT-O or TVT groups;P＞0.05]and in-hospital stay[(4.1±1.5)d vs.(4.5±1.8)d in TVT-O or TvT groups;P＞0.05]between the two groups.Grouts-Blaivas Score demonstrated that those two treatment groups did not differ significantly in 24-hour(93.6% vs.91.2%;P＞0.05)or long-term postoperative cure rate(94.5% vs.94.3%;P＞0.05).We suggested that TVT or TVT-O seemed to be equally effective in surgical treatment of SUI.However,TVT-O had advantage of relatively lower overall perioperative complication rate.

Objective To construct high-capacity ribosome display single-chain Fv library for selection of high affinity ScFv antibody.Methods We isolate human lymphocyte from peripheralblood(2 normal,3 gastric cancer,3 colonic cancer,1 pancreatic cancer,each 5 mL and 2 newborn,each 2 mL)and extract RNA for cloning whole human heavy chain and light chain gene by RT-PCR.VH and VL were rearranged randomly by SOEing(splicing by overlap extension,SOEing).Finally,the elements for in vitro screening such as T7 promoter and ribosome binding site were introduced while the SOEing products were amplified.Moreover,ribosome display template were verified by blue/white screening and further sequencing.Results We successfully constructed ribosome display ScFv library with a volume of 1.1?1013.Conclusion The construction of high-capacity ScFv library shed light on multiple therapeutic ScFv screening.

Objective To explore the perfect operation method for patients with vaginal vault prolapse.Methods Twenty six patients with vaginal vault prolapse who underwent transvaginal mesh repair by Prolift from January 2008 to June 2010 were analyzed retrospectively.Results The interval time between the first operation and this morbidity of ten patients who had underwent total hysterectomy for none FPFD ( ie:hysteromyoma et al) was ( 115.2 ±51.67) months,but the interval of sixteen patients who had underwent traditional repair operation (ie:transvaginal hysteromyoma and/or colporrhaphia anterior-posterior) for FPFD was (24.38 ± 13.43) months,which was markedly shorter ( t =6.75,P ＜0.01).The interval time between the first operation and the 2nd operation of the ten patients was ( 142.8 ±59.04) months,but that of the sixteen patients was (62.13 ± 44.51 ) months,which was significantly shorter ( t =3.97,P ＜0.01 ).Their age and POP-Q staging had no difference ( P ＞0.05).All operations were successfully performed by one gynecologist.The average operation time was ( 60.96 ± 7.88 ) minutes,the average blood loss was ( 119.23 ±27.53) ml,and there was no concomitant injury.All patients were followed up of 3 ～24 months.No vaginal erosion and prolapse recurrence happened,and the cure rate was 100％.Conclusions The Prolift system appeared to be a relatively safe and effective alternative to conventional surgeries for the treatment of vaginal vault prolapse.However,long-term follow-up still need to be performed.

AIM: To investigate changes of calcitonin gene-related peptide(CGRP) in myocardial stunning rats. METHODS: Rat in vivo myocardial stunning model was used. CGRP content in plasma and myocardium were determined by radioimmunoassay. RESULTS: Plasma level of CGRP increased significantly ( P

The clinical data of 42 patients with pelvic organ prolapse, who underwent laparoscopic sacral colpopexy using prolene meshes were retrospectively reviewed. During the operation prolene meshes were placed in the rectovaginal septum and vesicovaginal septum ,and the uterus was preserved in all cases.The mean operation time was (92 ± 12)min and the mean blood loss during the operation was (98 ± 11 )ml.Postoperatively, both prolapse and symptoms were significantly improved ( P ＜0. 01 ) according to the pelvic organ prolapse quantification (POP-Q) system. The operation is an effective and minimally invasive new technique which offers a chance for patients with pelvic organ prolaps who desire to preserve uterus.

Forty nine patients with vesicovaginal fistula underwent transvaginal repair by the use of Foley catheter in our hospital.The clinical data were retrospectively analyzed.The success rate of primary operation was 98% (2/49), the mean operation time was (85±8)min, the mean postoperative hospital stay was( 13±2) d, the rate of postoperative urine leakage was 2%(1/49), the mean bladder capacity was (378±53)ml.Transvaginal repair of vesicovaginal fistula by the use of Foley catheter is an effective surgical modality with satisfactory results.

Objective To analyze the electrophysiological characteristics of Hirayama disease and explore their significance for its diagnosis.MethodsElectrophysiological tests were performed on 18 patients who fulfilled the clinical criteria for Hirayama disease. Sixteen were males and 2 were females. The mean age was 24.9years old ( 19-58 years), and the mean case history was 5.2 years ( 1-40 years). The Hirayama disease was clearly unilateral in 10 patients and bilateral in 3, with 5 cases suspected of being bilateral. Motor neuron conduction velocity (MCV) and sensory neuron conduction velocity (SCV) were measured in the median and ulnar nerves.Electromyograms (EMGs) of the abductor digiti minimi, abductor pollicis brevis, extensor digitorum communis,brachioradialis muscle, biceps brachii and sternocleidomastoid were recorded in all cases. The MCV and SCV of the common peroneal nerve and an EMG of the tibialis anterior muscle were examined in one leg. The MCV and SCV of the ulnar nerve and EMGs of the abductor digiti minimi, extensor digitorum communis and brachioradialis muscles were inspected on the contralateral sides of 8 cases, including the patients suspected of suffering bilateral Hirayama disease. The MCVs of the median and ulnar nerves were examined segmentally by stimulating the nerves distally as well as proximally, and recording the amplitude, duration and area of compound muscle action potentials (CMAP) and changes in wave form, then determining whether there was a nerve conduction block.Results (1) No conduction block was detected in any median nerve or ulnar nerve among the 18 cases. (2) All the SCVs and sensory nerve action potentials of the median and ulnar nerves were normal. ( 3 ) All the MCVs and SCVs of the common peroneal nerve and the EMGs of the anterior tibialis muscles were normal. (4) MCV slowing in the upper limbs accounted for 41.3％ (19/44) of the examined nerves. The rates of MCV decrease were 72.2％ (13/18)in the ulnar nerve on the affected sides, 33.3％ (6/18) in the median nerve on the affected sides and 0％ (0/8)in the ulnar nerve on the contralateral sides. (5) Amplitude reduction in the CMAP in the upper limbs accounted for 81.8％ (36/44) of the examined nerves. The rates of amplitude decrease were 100％ (18/18) in the ulnar nerves of the affected sides, 77.8％(14/18) of median nerves on the affected side and 50％(4/8) of ulnar nerves on the contralateral side. ( 6 ) Upper limb EMGs revealed a rate of neurogenic damage of 47.0％ ( 62/132). The EMGs decreased in 100％ (18/18) of the abductor digiti minimi and abductor pollicis brevis on the affected side, 88.9％ (16/18) of extensor digitorum communis on the affected side, 62.5％ (5/8) of the abductor digiti minimi on the contralateral side, 37.5％ (3/8) of the extensor digitorum communis on the contralateral side,5.6％ ( 1/18 ) of the brachioradialis and biceps brachii muscles on the affected sides. There was no neurogenic damage of the contralateral brachioradialis muscle or the sternocleidomastoid on the affected side.Conclusions The electrophysiological features of Hirayama disease include unilateral or bilateral neurogenic damage in the upper limbs. According to the abnormal EMGs, spinal anterior horn cells on the affected sides were injured at C7-T1. C6and above C6 were rarely involved. The electrophysiological characteristics of Hirayama disease could provide a clear basis for localization and differentiation in Hirayama disease diagnosis.

ObjectiveTo study whether the abductor pollicis brevis been effected by the reinnervation of the Riche-Cannieu anastomosis in the median nerve injury cases.MethodsCollect 43 cases (29male,14 female,mean age 32.6)corresponds with the study needs: (1)The traumatic median nerve injury (proved by the results of electrophysiological examine and the clinic diagnose)on or below the forearm.(2)The existence of RCA was verified by the electrophysiological examine results,and the amplitude of electric potential was under 1mv.(3) Rule out the cases with the other injure of nerve or nervous system disease and cervical vertebra disease,diabetes patient.The analysis base on the results of 43 case's periodical examine,the periodical criteria as following: within 2-4th week,within the 2-4thmonth and 1 year after the injury.Results Forty-three cases had not obvious recovery indication of the median nerve under the clinical and electrophysiological aspect,eight cases of abductor pollicis brevis function improved quickly in 3 months,the relevant CMAP amplitude of Riche-Cannieu anastomosis increased apparently,the EMG (Electromyography)results of abductor pollicis brevis ameliorated accordingly.ConclusionIn the case of RCA combined with the median nerve injury,the abductor pollicis brevis fibra might be dominated by RCA reinnervation when losing domination of median nerve,the reinnervation process will much faster than the regeneration process of the broken nerve.
