Objective o observe the therapeutic effects of suspension-assisted functional rehabilitation training of motor function for patients with cerebral infarction. Methods Ninety-six patients with cerebral infarction were divided randomly into a treatment group and a control group. All patients were given routine medical treatment and routine limb movement therapy. Those in the treatment group also used an electrically-driven suspension device to aid in their functional rehabilitation training. The patients were assessed with a simplified Fugl-Meyer Motor Functional Assessment (S-FMMFA), and using the Postural Assessment Scale for stroke patients ( PASS), the Barthel Index (BI) and the 6-minute walking distance test before and after treatment and at a 6-month foliowup. Results The average S-FMMFA, PASS, BI and the 6-minute walk results in the treatment group were all significantly better than those in the control group. Conclusions Suspension-assisted training can significantly help improve limb movement function and ADL performance in cerebral infarction patients.

The TNA mRNA expression in 33 samples of cervical carcinoma and 28 samples of condyloma have been observed by using ~3H and Digoxigenin labeled TNF—? cDNA probes and in situ hybridization technique, we found that the results of in situ hybrdfzation with these two kinds of labeled probes were alike, the sensitivity with ~3H labeled probe was slightly higher than that with Digoxigenin labeled probe. Nevertheless, the nonisotope probe would be used more and more in future because of its safety, rapidity and convenience in work.

Purpose To explore the role of histone H2B monoubiquitination in primary colonic carcinoma and clinicopathological pa-rameters of colonic carcinoma. Methods To detecte the expression of histone H2B monoubiquitination in 116 cases of primary colonic carcinoma and 15 cases of normal colonic mucosal tissue by avidin-biotin-peroxidase complex ( ABC)-immunohistochemistry. Results The level of histone H2B monoubiquitination was significantly reduced in poorly differentiated colonic carcinoma 19. 4% (6/31) compared with that of well-differentiated colonic carcinoma 49. 4%(42/85), moderately differentiated colonic carcinoma 49. 4% (42/85) and normal colonic mucosal tissue 86. 7% (13/15) (P<0. 05). The expression of histone H2B monoubiquitination was closely correlated with tumor differentiation, Dukes stage, TNM stage and lymph node metastasis (P<0. 05), but not depended on sex or age (P>0. 05). Conclusion Histone H2B monoubiquitination is obviously associated with the progression of primary colonic carcinoma. Although its specific mechanism still remains unclear, histone H2B monoubiquitination could be a novel potential molecular marker for early diagnosis, clinic treatment and prognosis evaluation.

PurposeIt is important to keep the consistency of CT perfusion imaging (CTP) measurement in the evaluation of intracranial disorders. The purpose of this paper is to probe into the consistency of basal ganglia hemodynamic characteristics in normal rabbits with CTP measurement in the mode of volume helical shuttle (VHS).Materials and Methods Brain CTP scans of 10 healthy rabbits were carried out in the VHS mode. The images derived from CTP were separately analyzed by two radiologists (A and B) with different experiences. ROIs were placed in the bilateral basal ganglia of the subjects and parameters such as cerebral blood volume (CBV), cerebral blood flow (CBF) and mean transit time (MTT) were measured three times in each rabbit. Thirty days later, radiologist A analyzed the CTP images again with the same method. Differences of parameters in bilateral basal ganglia measured by different radiologists at different periods were compared respectively and consistency of the measurements was further assessed.Results There was no significant difference among the three measurements of CBV, CBF and MTT in bilateral basal ganglia (F=0.162, 0.050 and 0.488,P>0.05). TheICC of CBV, CBF and MTT measured by the two radiologists for the first time were 0.84, 0.81 and 0.79; while theICC of CBV, CBF and MTT measured by radiologist A twice were 0.80, 0.89 and 0.84, which showed that the results had good consistency measured by different radiologists at different times.Conclusion With the same post-processing software, the consistency of CTP of basal ganglia in the VHS mode is satisfactory in healthy rabbits, which suggests this technique may be a suitable means in the evaluation of basal ganglia hemodynamics in animal models.

In the process of evolution, pathogenic Streptococcus pyogenes secretes an immunoglobulin G-degrading enzyme IdeS which can specifically cleave the hinge region of immunoglobulin G in order to escape the immune response against the host. On the one hand, IdeS can be used for IgG fingerprinting as a tool enzyme combined with mass spectrometry technology. On the other hand, IdeS can be used to treat the antibody-responsive diseases produced by autoimmunity as a therapeutic protein. In this study, the backbone of plasmid pCold was used to construct two expression vectors of recombinant protein IdeS, which were heterologously expressed in Escherichia coli Shuffle T7. After purification by affinity chromatography, the recombinant IdeS activity was detected and their activity differences between the two were compared. Among them, the yield of the recombinant IdeS containing the His6-tag at the N-terminus was 4 mg·L^-1, and the cleavage reaction with antibody IgG1 at 1∶200 (m/m) at 37 ℃ for 30 min could complete. However, the yield of the recombinant IdeS containing both the N-terminal His6 tag and the C-terminal silica affinity tag (silica bing peptide, SiBP) is 1.5 mg·L^-1, and the degradation reaction with antibody IgG1 at 1∶20 (m/m) at 37 ℃ for 30 min could reach the end. The C-terminal fusion peptide has a great influence on the yield and activity of IdeS, which is not conducive to subsequent application in drug development. Above all, the recombinant IdeS containing the His6-tag at the N-terminus expressed by this system has high activity and can fully meet the needs of antibody drug development and mapping analysis of IgG.

Objective To report three cases of localized primary sclerosing cholangitis (PSC) mimicking a hilar cholangiocarcinoma (Klatskin tumor) and to summarize their clinical characteristics and the ways to differentiate them through a literature review.Method The clinical data of three patients with localized PSC mimicking a hilar cholangiocarcinoma were retrospectively analyzed.The characteristics of laboratory tests and imaging examination were reviewed,and therapy and prognosis were discussed.Results The three patients were all diagnosed to have a hilar cholangiocarcinoma preoperatively,but the diagnosis of PSC was confirmed by histopathology post-operatively.All the three patients had elevated CA19-9,2 patients had elevated anti-nuclear antibody (ANA) and 2 patients had elevated IgG.All the three patients underwent surgical resection and histopathological study showed chronic inflammation of the hilar bile ducts and cholangitis of the intrahepatic portal area.The three patients were followed up from 7 months to 8 years with no symptoms.Conclusions Localized PSC is rare and it can casily be misdiagnosed as a hilar cholangiocarcinoma.Biopsy before surgery is helpful for the differential diagnosis but it is difficult to get a good biopsy sample.Surgical resection is an effective treatment.

Objective To evaluate the clinical presentations,pathologic characteristics,and the diagnosis and treatment of eosinophilic cystitis.Methods Two cases of eosinophilic cystitis were analyzed,and the relevant literature was reviewed.Case 1,a 63-year-old man,complained of voiding urgency and frequency,dysuria,intermittent hematuria,and lower abdominal pain.Cystoscopic examination showed that an about 5cm?3cm abnormal focus was 0.2-0.4 cm above bladder mucosa at the fundus of the bladder.Case 2,a 42-year-old woman,complained of voiding urgency and frequency,dysuria,and suprapubic pain with intermittent hematuria.Cystoscopic examination showed that about 4 cm?3 cm?2 cm abnormal foci of cauliflower-like were 0.3-0.4 cm above bladder mucosa at the fundus and neck of the bladder.Imaging examinations(Bultrasound,CT and IVU) showed diffuse thickening of bladder wall and tumor-like lesions.They both underwent transurethral resection of the lesions and were treated with oral steroids and antibiotics.Results Postoperative pathology confirmed eosinophilic cystitis in both cases.The follow-up was 6 months.The voiding symptoms disappeared,and imaging examinations showed no space-occupying lesions of the bladder in them.Up to now,there has no evidence of relapse.Conclusions Eosinophilic cystitis is a very rare tumor-like inflammatory disease.It is easily misdiagnosed as bladder neoplasm.Cystoscopy and biopsy are gold standard for the diagnosis.Current treatment modalities include transurethral resection of the bladder lesion along with nonspecific medical therapy.
