Objective To analyze the clinical characteristics and determine the early diagnosis and treatment of mesenterie venous thrombosis (MVT). Methods Clinieal data of 31 cases with MVT were analyzed retrospectively. Results Of all 31cases,19 patients presented acute MVT. Abdominal pain was the first onset symptom and then progressively exacerbated; peritoneal irritation and ascites developed in 57.9% and 68.4 % patients with sign of ascites respectively. 13 patients were diagnosed by abdominal CT scan or selective mesenterie angiography; the detectable rate of CT for acute MVT was 83.3%. The level of plasma D-Dimer was increased in 93.3% patients with acute MVT. 13 patients underwent surgical treatment, among them,6 cases received anticoagnlafion treatment,4 cases recrudersced and 3 died. 12 chronic MVT patients had no symptoms and were identified through abdominal CT 8 cases developed upper gastrointestinal hemorrhage and 2 died. Conclusion The nonspecifie nature of the abdominal symptoms often delays the diagnosis of MVT and leads to high mortality. Abdominal CT is valuable diagnosis method for MVT and anticongulation treatment and operation are effective managements.

AIM: To investigate the possibility of 3T3 fibroblast growth on blood fibrin clot in culture medium with recombinant human basic fibroblast growth factor (rhbFGF). METHOD: Growth of the cells on blood fibrin clot was studied by phase-contrast, scanning and transmission electron microscopy and by Giemsa stain and MTT assay. RESULTS: The optimal concentration of rhbFGF for proliferation and survival of the cells was 100 ng/mL. The cells also grew on blood fibrin clot scaffold in the low-serum medium containing 100 ng/mL rhbFGF, and a greater number of the cells survived after 48 hours incubation compared to that after 24 hours. The elongated filopodia appeared to bridge the gaps among the fibroblasts after 24 hours incubation. Further incubation to 72 hours, a greater number of platycytes were found to be joined together by lamellopodia. CONCLUSION: 3T3 fibroblasts could grow and survive on blood fibrin clot in the low-serum medium containing rhbFGF, and a combination of blood fibrin clot and rhbFGF may have over proportional effects on wound healing.

Objective: To study the clinical features of primary biliary cirrhosis (PBC) in order to facilitate cognition of the disease. Methods: Clinical data of 42 patients clinically and/or histologically diagnosed with PBC were reviewed. Anti mitochondrial antibody (AMA) negative/positive patients as well as the patients who were/were not associated with Sj?gren Syndrome (SS) were compared in terms of clinical, biochemical and immunological features. Results: Among the 42 patients, 78.6%(33/42) of the cases were females; the mean age at diagnosis was (61.1?10.8) years. The most frequent symptoms were fatigue. Serum alkaline phosphatase (ALP), ?-glutamyltranspeptidase (?-GT) and total bile acid (TBA) levels were markedly elevated in the majority of the patients, whereas ALT and AST levels were mildly to moderately elevated. Thirty-one patients had a total bilirubin (TBil) level above normal. The levels of TBil and prothrombin time had positive correlationship with years of the course (P=0.000, r=0.696; P=0.005, r=0.424), whereas serum albumin level had negative correlationship with years of the course (P=0.002, r=-0.462). Thirty-seven patients had elevated serum IgM and 34 patients were AMA/AMA-M2 positive. AMA negative and AMA positive patients were similar in terms of clinical manifestations and liver biochemistries findings. Serum IgM and IgA levels were significantly lower, whereas total cholesterol level was higher in AMA negative patients when compared with AMA positive cases. Fifteen cases were associated with SS, which were similar in terms of clinical, biochemical and immunological features when compared with the PBC patients were not associated with SS. Conclusion: PBC is mostly found in middle aged and old women. Elevated serum ALP, TBA and ?-GT levels together with positive AMA/AMA-M2 can help to diagnose PBC. AMA negative PBC patients are characterized by relatively lower serum IgM and IgA levels and higher total cholesterol level. PBC patients who are associated with SS have not substantial differences in the clinical, biochemical and immunological spectra of the disease.

Objective To evaluate the clinical application of May-Grunwald-Giemsa staining followed by fluorescence in situ hybridization (MGG-FISH) technique in the differentiation diagnosis of Ph-chromosome positive acute lymphoid leukemia (Ph + ALL) from chronic myeloid leukemia in lymphoid blast crisis(CML-LBC). Methods The bone marrow smears of 4 patients with Ph+ ALL, 4 patients with CML-LBC, 1 patient with CML in myelocytic blast crisis complicated with lymphoma and 1 patient with CML in mixed blast crisis were assayed with the MGG-FISH technique in which the spectrum green labeled BCR and spectrum orange labeled ABL dual color dual fusion probes were used. Based on the morphological classification, the percentages of BCR-ABL positive cells were subsequently determined respectively in the erythroid, myeloid and lymphoid hneages for the 10 specimens. Results According to the MGG-FISH analysis, the erythroid lineage was not involved in the 4 Ph+ ALL specimens without BCR/ABL positive cells. While the BCR/ABL positive percentage of myeloid cells was 11% (1/9), 8% (1/12), 0% (0/8) and 10% (1/10) respectively and that of lymphoid cells was 97% (76/78), 98% (87/89), 98% (97/99) and 97% (75/77) respectively. On the other hand, the BCR/ABL positive percentage was 100% (8/8), 91% (10/11), 82% (9/11), 88% (7/8) in the erythroid lineage, 89% (8/9), 96% (94/98), 100% (47/47), 98% (40/41)in the myeloid lineage and 96% (78/81), 93% (52/56), 96% (68/71), 95% (58/61) in the lymphoid lineage respectively for the 4 CML-LBC specimens. The BCR/ABL positive percentages of the other 2 specimens were all above 80% and through MGG-FISH analysis we also identified the source of the malignant clones and ascertained the diagnosis of the 2 patients. Conclusions The MGG-FISH technique has proved useful in providing rapid and precise differentiation between Ph + ALL and CML-LBC. The source of the malignant clones can also be analyzed by this technique.

Objective To investigate the therapeutic effects of recombinant human endostatin (RHES) combined with radiotherapy on brain metastases (BM) of non-small cell lung cancer (NSCLC) and the patients suitable for this therapy.Methods Eighty patients with BM of NSCLC were randomly divided into RHES combined with radiotherapy group (combination group) and radiotherapy alone group (each group with 40 patients).The short-term effective rate,overall survival time,cerebral edema index and adverse reactions were observed and the expressions of vascular endothelial growth factor receptor 2 (VEGFR2) protein in primary lesions were detected with immunohistochemical method in all patients.Results Compared with radiotherapy alone group,brain edema was significantly relieved (t=4.9,P=0.000) and there were no marked adverse reactions in combination group.In short-term effective rate,there was no statistical significance in total population (n=80,90％ vs.75％,x2=3.11,P=0.07),but there was statistical significance in the patients with positive VEGFR2 (93％ vs.67.7％,x2=6.31,P=0.012).In overall survival time,there was no statistical significance in total population (n=80,P=0.35,95％ CI:0.25-1.30) or in the patients with positive VEGFR2 (P=0.109,95％ CI:0.40-1.34).Conclusion Compared with radiotherapy alone,RHES combined with radiotherapy can relieve brain edema in the patients with BM of NSCLC and obtain better short-term effective rate in the patients with positive VEGFR2.

ObjectiveTo investigate the efficacy of co-infusing cord blood (CB) as the third party cells on graft versus host disease (allo-GVHD) prophylaxis after unrelated or haploidentical donor allogeneic hematopoietic stem cell transplantation (allo-HSCT).MethodsFrom 2007 to 2011,41 patients receiving unrelated or haploidentical donor allo-HSCT were analyzed retrospectively.Twenty-five patients received one unit of HLA 4/6-6/6 matched CB one day before SCT as CB group,and median MNC dose was (1.64 ± 0.49) × 107/kg.Sixteen cases not receiving CB served as control group.All patients received antithymocyte globulin,cyclosporine,methotrexate,and mycophenolate mofetil as GVHD prophylaxis.The incidence and severity of aGVHD,and treatment-related mortality were compared between two groups.ResultsThe main clinical characteristics in both groups were comparable.The cumulative incidence of aGVHD in CB group and control group was 44.0％ versus 68.8％ respectively (x2 =2.403,P＞0.05).The cumulative incidence of grades Ⅲ to ⅣV aGVHD in CB group and control group was 16.0％ and 37.5％ respectively (x2 =2.445,P＞0.05).The 100-day treatment-related mortality in CB group and control group was 12.0％ and 12.5％ respectively (x2 =0.002,P＞0.05).ConclusionCord blood as the third party cells might reduce the incidence and severity of aGVHD in unrelated or haploidentical donor HSCT.The efficacy and the mechanism of this strategy need to be further explored by prospective randomized controlled trials.

Objective To report the clinical and peripheral neuropathological findings in two patients with autosomal recessive Charcot-Marie-Tooth disease 2K(AR-CMT2K).Methods Case one was a nine year-old girl.She had distal weakness of lower limbs for six years, with calf atrophy and contracture of Achilles tendon for three years.Case two was an eight year-old boy.He had distal weakness of lower limbs with contracture of Achilles tendon and calf muscle atrophy for three years, and proximal weakness of low limbs for two years.The motor nerve conduction velocities in median nerves were 48.1 m/s in case one and 47.6 m/s in case two.The compound motor action potential amplitude of median nerves decreased by 46% in case one and 69% in case two.Sural nerve biopsies and gene targeted next-generation sequencing were performed in both patients.Results Density of myelinated fibers was 8 407/mm2 in case one and 7 714/mm2 in case two.The ratio of myelinated fibers with diameter over 8 μm was 2.6% in case one and 0 in case two.Both patients had small regenerating cluster of myelinated fibers.Thin myelinated fibers appeared in case one.In case two, atypical onion bulb formations with focal folded myelin appeared, and electromicroscopy revealed mitochondrial aggregate in axons.Compound heterozygous mutations of ganglioside-induced differentiation associated protein 1 gene were detected in both patients, including c.767A>G(p.H256R) and c.466G>A (p.A156T) in case one and c.767A>G and 845G>A(p.R282H) in case two.Conclusions Contracture of Achilles tendon may appear in early childhood of AR-CMT2K patients.The main pathological changes in sural nerve are loss of large myelinated fibers, mitochondrial aggregate in axons and myelin abnormalities.

Objective To explore the influence of inhaled glucocorticosteroid on ?-glutamylcysteine synthetase(?-GCS) in inflammatory cell of sputum in children with asthma.Methods Twenty-two asthmatic children were divided into 2 groups according to treatment.The children who were treated by inhaled budesonide combined with salbutamol were due to group A and the others inhaling salbutamol only were due to group B,the healthy children were acted as healthy control group(group C).The glutation(GSH),total GSH and the activity of ?-GCS in sputum were measured respectively;Expression of ?-GCS in inflammatory cell of sputum were detected by immunohistochemistry;the expression of ?-GCS heavy chain(?-GCS-h) mRNA were detected by reverse transcriptase-polymerase chain reaction(RT-PCR).Results 1.The total GSH[(1.08?0.14) ?mol/L] and oxidized glutathione(GSSG)[(0.37?0.09) ?mol/L] were decreased in sputum of group A of post-treatment compared with pre-treatment(Pa

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P
