ObjectiveTo introduce clinical experience of the modified lateral crural reverse island skin flap with two sets of blood supply system for aged ankle & foot soft tissue defect.MethodsOn the anatomy base that cutaneous artery branches of lateral crural reverse island skin flap and perforating branches of sural neurocutaneous vascular flap were originated from peroneal artery, we designed the modified lateral crural reverse island skin flap located in posterolateral cruris treated for aged ankle & foot soft tissue defect. The modified flap had two sets of blood supply system which were from lateral crural flap and sural neurocutaneous flap.ResultsAll 11 flaps survived. The skin grafting of donor sites healed well. Followed up 3-9 months, six cases were satisfactory. Five cases with extensor defect were regained by tendon transplantation after 3 months of the operations.Conclusion The modified lateral crural reverse island skin flap with two sets of blood supply system is a good method for aged ankle & foot soft tissue defect.

Objective To explore the efficacy and adverse reactions of improved VTD regimen (pirarubicin combined with vincristine and dexamethasone) plus low-dose thalidomide in patients of newly diagnosed multiple myeloma(MM).Methods Twenty-nine cases of newly diagnosed MM were enrolled in this study.The improved VTD regimen was intravenous injection vincristine 2 mg/d on the first day,intravenous drip pirarubicin 20-30 mg/d from the first day to the second day,and intravenous drip dexamethasone 8 mg/d from the first day to the tenth day.Twenty-eight days was one course of treatment.Response and adverse reactions were evaluated after 4 course of treatment.On the first day of chemotherapy,all the patients were orally administered thalidomide 50 mg/d.Three days later,thalidomide was added to 100 mg/d and chronically maintained if toxicities could be tolerated.Results There were 3 cases(10.3％) in complete response,12 cases (41.2％) in very good partial response,10 cases (34.5％) in partial response,3 cases (10.3％) in stable disease,and 1 case(3.5％) in progressive disease.The overall response rate was 86.2％.Main adverse reactions were myelosuppression,asthenia and constipation,all could be tolerated.Conclusion It has significant response rate and less side effects of improved VTD regimen plus low-dose thalidomide for the patients of newly diagnosed multiple myeloma,and deserves further clinical practice.

Objective To examine the differences in the structure of brain white matter among deficit schizophrenia, nondeficit schizophrenia and healthy controls by using voxel-based morphometry (VBM). Methods Ten deficit schizophrenic patients, eleven nondeficit patients and fifteen healthy comparison subjects participated in the study. All the subjects were scanned by GE Twin Speed 1.5T MRI system. Whole brain, voxel-wise analyses of regional white matter volume were conducted by the VBM toolbox on the Matlab7.6 and SPM5. t -test was then used for the comparison between groups. Results Compared to the healthy controls, nondeficit schizophrenic patients significantly decreased the density of gray matter in the frontal, parietal, temporal, occipital lobe and basal ganglia , while the deficit patients showed the characteristically broad and significant decreasion in the frontal lobe, including left medial frontal gyrus, bilateral inferior frontal gyrus, left middle frontal gyrus, and left orbital gyrus (Cluster ≥ 30 mm3, P<0.01). Moreover, deficit patients showed the decreasion in the temporal cortex and the limbic lobe (right insula). Relative to the nondeficit schizophrenic patients, deficit patients had significant regional gray matter decreases in the left medial frontal gyrus, bilateral inferior frontal gyrus, right precentral gyrus, and right superior temporal gyrus (Cluster ≥ 30 mm3, P<0.01). Conclusion Structural heterogeneity in schizophrenia may relate to specific patterns of gray matter density reductions in deficit and nondeficit patient. However the two subtype of schizophremia patients share a common prefrontal-temperal pattern of structural brain alterations.

Objective To investigate the clinical features and TCD-detected microembolic signals in patients with hypercoagulability related multiple acute cerebral infarcts within non-single arterial territories, and to explore the possi?ble underlying mechanisms. Methods A retrospective review was conducted on all clinical, laboratory, radiological and TCD monitoring records from patients with hypercoagulability related multiple acute cerebral infarcts within non-single arterial territories, who admitted to the neurology department in our hospital. Results The data from twenty-two cases were finally included in this study. All patients presented with acute-onset localized neurological dysfunction, e.g. hemi?paresis, aphasia, hemiparesthesia, dysarthria, hemianopsia and cortical blindness. Their hypercoagulability related diseas?es included 10 cases of systemic malignancy, 5 moderate to severe hyperhomocystynemia (HCY>50μmol/L), 2 nephrot?ic syndrome, 2 antiphospholipid syndrome, 1 ulcerative colitis, 1 polycythemia vera,1 paroxysmal nocturnal hemoglobin?uria. In 18 cases, the hypercoagulability related diseases were diagnosed after their initial stroke onset. DWI showed mul?tiple disseminated acute cerebral infarcts in non-single arterial territories involving bilateral anterior or anterior plus pos?terior cerebral circulation simultaneously. Foci involved lobar cortex/subcortex of cerebral hemisphere in 22 cases, deep cerebral hemisphere in 12 cases, cerebellum foci in 10 cases,brainstem foci in 2 cases. TCD revealed microembolic sig? nals in ten of 22 patients monitored. Conclusions Patients with multiple acute cerebral infarcts involving non-single arte?rial territories, should be screened for hypercoagulability as in that hypercoagulability and microembolism might be in?volved in the etiology of cerebral infarction.

Objective To evaluate the treatment effect of hand reconstruction with bilateral multiple toe transplantation. Methods There are four schedules as follow applied in 102 cases: (1) bilateral second toes to thumb and index finger transplantation in 86 cases; (2) wrap-around flap to thumb and second toe on opposite side to index or middle finger transplantation in 11 cases; (3) wrap-around flap to thumb and bilateral second toes to index and middle fingers transplantation in 8 cases; (4) bilateral wrap-around flap to bilateral thumb and second toe to index finger transplantation in 1 case. Results All reconstructed finger survived in 102 cases except for partial wrap-around flap necrosis in one case and second toe in two cases. Sixty-two patients got more than one-year following up. Two points discrimination in reconstructed finger was between 8 to 14 mm in all cases. The reconstructed finger grew synchronously with toe among children. Thumb opposition function recovered in all cases except for one case. Donor site: no limp or hallux eversion observed in all cases. Conclusion There is less damage on foot and most hand function recovery using bilateral multiple toe transplantation to repair hand or multiple fingers defect.

Objective:To investigate the risk factors of acute pancreatitis (AP) complicated with thrombotic diseases.Methods:Clinical data of 5 223 patients with AP admitted to the General Hospital of Ningxia Medical University from January 2015 to September 2020 were retrospectively analyzed. They were divided into thrombosis group and non-thrombosis group according to whether they were complicated with thrombotic diseases. The following data were recorded: gender, age, past history, time of onset, etiology, severity grade of AP, BISAP score, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer(D-D), fibrinogen(FIB), white blood cell count(WBC), platelet count (PLT), lactate dehydrogenase (LDH), blood glucose level, with or without hypoalbuminemia, hypertriglyceridemia and hypercholesterolemia, date of diagnosis, location of thrombus, clinical manifestations and anticoagulant therapy. Univariate and Logistic multivariate regression analysis were used to analyze the risk factors of AP complicated with thrombotic diseases. The receiver operating characteristic (ROC) curve was drawn, the area under the curve (AUC) was calculated, and the efficacy of independent risk factors in predicting AP complicated with thrombotic diseases was evaluated.Results:46(0.88%) of 5 223 patients with AP were complicated with thrombosis, which occurred 8.50(2.00-15.00) days after the onset of AP; the age of onset was 66 (52-74) years; the patients with thrombotic diseases were mostly SAP patients (23/46, 50%); the most common type was deep venous thrombosis in lower extremity (19/46, 41.3%); 37 patients (80.4%) received regular anticoagulant treatment after finding thrombus, and no bleeding was found during hospitalization. Univariate analysis showed that the age of patients with thrombosis was higher than that of patients without thrombosis, APTT value was prolonged, D-D value was increased, WBC was decreased and SAP was more in AP severity, the number of patients with BISAP score ≥3 was increased significantly, and the differences were statistically significant ( P<0.05). Multivariate logistic regression analysis showed that AP severity ( OR=3.017, 95% CI 1.799-5.061, P<0.001) and age ( OR=1.029, 95% CI 1.000-1.059, P=0.049) were independent risk factors for AP patients complicated with thrombosis. The AUC of AP severity and age in predicting AP complicated with thrombotic diseases were 0.714 and 0.625, respectively. The sensitivity was 67.4% and 47.8%, and the specificity was 70.6% and 77.9%, respectively. Conclusions:The severity grade and age of AP were independent risk factors for AP complicated with thrombotic diseases. Early vigilance and clinical intervention should be given.

Objective To analyze some related causes of hypocytosis or hematocytosis with bone marrow dry pumping. Methods Bone marrow histology, reticular fiber staining and selective immunohistochemical staining were performed in 34 bone marrow dry pumping patients with hypocytosis or hematocytosis in the Second People's Hospital of Lianyungang from January 2012 to August 2017. Results All the patients showed dizziness, fatigue, splenomegaly, night sweats and bleeding, including primary myelofibrosis (17 cases, 50.0 %), chronic myelocytic leukemia (4 cases, 11.8 %), acute myelocytic leukemia (2 cases, 5.9 %), acute lymphoblastic leukemia (1 case, 2.9 %), myelodysplastic syndrome (2 cases, 5.9 %), multiple myeloma (2 cases, 5.9 %), non-Hodgkin lymphoma with bone marrow infiltration (2 cases, 5.9 %), polycythemia vera (1 case, 2.9 %) and bone marrow metastatic tumor (3 cases, 8.8 %). The bone marrow proliferative degree in primary myelofibrosis group was mainly "grade Ⅱ" to "grade Ⅳ", and the non primary myelofibrosis group was mainly "grade Ⅲ" to "grade Ⅴ", and the differences of proliferative degree component between them were statically significant (χ2＝ 12.900, P＝ 0.004). The fibrosis level in primary myelofibrosis group was mainly "grade 2" to "grade 3", and the non primary myelofibrosis group was mainly "grade 1" to "grade 2", and the differences of myelofibrosis degree component between them were also statistically significant (χ2＝ 12.692, P＝ 0.003). Conclusions Hematological malignancies, especially primary myelofibrosis, are the common causes of bone marrow "dry pumping". Bone marrow histology, reticular fiber staining and selective immunohistochemical staining are of great significance in the etiological diagnosis.

Objective To investigate the clinical and laboratory features of IgG-2κ light chain multiple myeloma. Methods The clinical data and laboratory results of 2 multiple myeloma (MM) patients with IgG-2κ light chain were analyzed and the related literatures were reviewed. Results Two male and 1 female patients were 50-82 years old and mainly suffered with backache, infection, anemia and renal dysfunction. Multiple osteolytic bone destruction was detected in X-ray as well as magnetic resonance imaging (MRI). The level of serum IgG was normal, slight or obviously increased, but the levels of IgA and IgM were decreased. The levels of κ light chain in serum and urine were both increased significantly, and Bence-Jones protein was positive. Double M protein peaks of serum in γ area were detected by protein electrophoresis in 2 patients. A single band of IgG and double bands of light chain κ were revealed by immunofixation electrophoresis. Bone marrow smear showed that abnormal plasma cells were increased obviously. One patient gave up chemotherapy because of lung infection, acute left heart failure and acute renal failure, the others 2 patients achieved partial remission and stable disease by receiving DVD and VAD chemotherapy. Conclusions IgG-2κ light chain MM lacks typical clinical presentation, but some laboratory characteristics may be different from those of IgG-κ light chain. Further researches are needed to confirm whether or not it belongs to biclonal MM.
