Objective:To investigate the clinical and pathological features, treatment, and prognosis of gray zone lymphoma (GZL) .Methods:From July 2, 2013, to February 10, 2021, the clinical and pathological features, treatment, and outcomes of five patients with GZL at the Blood Diseases Hospital, Chinese Academy of Medical Sciences were studied retrospectively.Results:There were one male and 4 females, with a median age of 28 (16-51) years at diagnosis. Four patients had mediastinal (thymic) involvement, two of which had superior vena cava obstruction syndrome, and 3 patients had extra-nodal involvement. There was one case with a limited Ann Arbor stage and 4 cases with a progressive stage. Three patients had cHL-like pathomorphology with scattered Hodgkin-like cells, strongly positive for CD20, positive for CD30, and CD15 was negative; the other two patients had both cHL and DLBCL morphology, with some areas resembling Hodgkin cells and some areas resembling immunoblasts, strongly positive for CD30, and CD15 but negative CD20. Two patients were treated with cHL-like regimens for induction and achieved only partial remission; after salvage therapy with enhanced DLBCL-like regimens, all achieved complete remission (CR) . Three patients were treated with enhanced DLBCL-like immunochemotherapy regimens for induction, and two patients were effective, one of whom achieved CR. Four patients who did not achieve CR were given second or third-line salvage therapy, and all of them recovered. One patient lost parity, one died of disease progression at 35.9 months after diagnosis, and the remaining three maintained sustained remission.Conclusions:GZL is uncommon, usually affects younger patients, is mediastinal and is diagnosed using path morphology and immunophenotype. Patients with newly diagnosed GZL appear to be more sensitive to DLBCL-like immunochemotherapy regimens; relapsed or refractory patients were tended with non-cross-resistant combination chemotherapy or with new drugs.

Objective: To study the relationship between the single nucleotide polymorphism of HLA⁃A rs3132682 and the risk of liver cancer. Methods: The author selected 291 cases of liver cancer patients in Yanbian area as the experimental group and 272 healthy people as the control group. The genotypes and allele frequencies of the two loci were detected by MassARRAY SNPS mass spectrometry. Odds ratio (OR) and 95% confidence interval (CI) were calculated by unconditional logistic regression to evaluate the risk of liver cancer in patients with different genotypes. Results: There were G and C alleles in HLA⁃A rs3132682 locus , GG , GC and CC genotype. After adjusting for confounding factors in HLA⁃A rs3132682 locus , there was correlation between CC genotype and the risk of liver cancer compared with GG genotype (P < 0. 05) . Stratification analysis showed that compared with the population with CG + GG genotype , the Korean population with CC genotype increased the risk of liver cancer by 3. 331 times. Conclusion The single nucleotide polymorphism of HLA⁃A rs3132682 is correlated with the risk of liver cancer in Yanbian area.

CD70/CD27 pathway plays an important role in human immune regulation.The role of CD70/CD27 pathway in immune regulation is mainly to promote the activation and proliferation of T cells,induce the differentiation and formation of effector T cells and memory T cells,and interfere with regulatory T cells.In addition,the high level of CD70 expression in some tumor cells provides a new way for tumor immunotherapy.

Objective To analyze the risk factors of prolonged residence time in ICU after surgery for Standford type A aortic dissection.Methods A total of 361 patients with surgery for Standford type A aortic dissection were selected.They were divided into prolonged residence time in ICU group and normal residence time in ICU group.Single factor analysis was used at first,and the significant factors analyzed in single factor analysis were analyzed by Multi factor analysis.Results Logistic regression analysis showed that smoking history,systolic blood pressure,white blood cell count,serum creatinine,low density lipoprotein cholesterol,thrombosis in the false lumen,apolipoprotein A-I,ventilator time were associated with prolonged residence time in ICU.Conclusion Smoking history,systolic blood pressure,white blood cell count,serum creatinine and ventilator time are the independent risk factors for prolonged residence time in ICU,and low density lipoprotein cholesterol,apolipoprotein A-I,thrombosis in the false lumen are the protective factors for prolonged residence time in ICU.

Objective To describe our experience and method of reconstruction after resection of tumors around inner canthus and nasion in the elderly. Methods The line between outer and inner canthus was considered during reconstruction.If the surface of wound after resection was above this line,glabellar flap was used to reconstruct the upper part and the residual defect was repaired with advancement of lower eyelid and rotation of flap.If the surface of wound was below this line,lower eyelid flap was used and the residual defect was reconstructed with glabellar flap. Results All flaps survived without any significant complications.9 cases among 15 patients were followed up from 1 to 24 months.Repaired tissues all matched well with surrounding tissue in color,texture,and outline.Eyelid and medial canthal were not disturbed and there was no tumor recurrence.Scars were smoothy,soft and hidden with satisfactory appearance and vision. Conclusions Single local flap or combined local skin flaps around the nasion and inner canthus is one of reconstruction methods to get satisfactory cosmetic effect or facial morphology.

OBJECTIVE: To test the association of K469E, the common intercellular adhesion molecule-1 (ICAM-1) polymorphism with chronic obstructive pulmonary disease (COPD) and expression of ICAM-1 in Han people of Central and South Region in China. METHODS: A case-control study was done on 91 patients with COPD and 80 matched controls of Han people from central and south region in China, mainly from Hunan Province. Genomic DNA was extracted from white blood cells. ICAM-1 sequences were amplified by PCRand analyzed by agarose gel electrophoresis. Genotypes were defined by base sequencing. In addition, soluable intercellular adhesion molecule-1 (sICAM-1) serum levels were measured in 86 people picked out randomly from the COPD group and the control group. RESULTS: There was no difference in the frequency of the genotype and allele between the COPD group and the controls, but compared with those who were not very severe, the frequency of KE/ EE genotypes and E allele in COPD patients at very severe stage was significantly higher (10/16 vs 26/75, 12/30 vs 20/150, P<0.05). The level of sICAM-1 increased in the COPD patients, with negative correlation to forced expiratory volume in one second for the percentage of predicted value (FEV1%). But in both COPD patients and controls, the level of sICAM-1 did not differ significantly in different genotypes(P>0.05). CONCLUSION K469E polymorphism of ICAM-1 may not affect the susceptibility of COPD and the expression of ICAM-1 in Han people from central and south of China in this study, but carriers of E allele are at high risk of developing severe stage of COPD.

Objective To summarize and analyze the clinical and epidemiological characteristics of 585 cases of cutaneous sporotrichosis collected in Jilin province in the last 3 years. Methods A retrospective study was conducted on sporotrichosis cases diagnosed at the Department of Dermatology in the hospital from 2007 to 2009. Results Totally, 585 cases were included in this study. Among these patients, the male/female ratio was 1:1.35 with an average age of 40.5 years and average duration of symptoms of 6.78 months.The age at onset was mainly between 51 and 60 years (22.05%). Sporotrichosis seemed more frequently to occur in winter and spring. The majority (94.19%) of the patients were rural habitants, and 149 (25.47%) patients recalled history of trauma. Fixed form was the most common clinical presentation (56.58%), followed by lymphocutaneous form (39.66%), cutaneous disseminated form ( 1.88% ) and undefined form ( 1.88% ). The predilection sites of sporotrichosis were extremities (50.94%) and face (43.76%). The treatment of sporotrichosis included a 10% solution of potassium iodide, itraconazole and terbinafine alone or in combination. Two hundred and fifty patients were lost to follow up. Of the remaining 335 patients, 289 were cured with an average treatment duration of 2.09 months, 46 were still under follow-up or treatment. Conclusions The case load of sporotrichosis in Jilin province has remained high in recent years. The clinical and epidemic features of sporotrichosis cases in this report are similar to those in previous reports, but the proportion of middle-aged patients and atypical cases increases. Potassium iodide solution, itraconazole and terbinafine are effective and safe for the treatment of sporotrichosis.

Objective To investigate the effect of CD151 gene therapy on improving myocardial function in swines with myocardial infarction. Methods CD151, antisense CD151 and green fluorescent protein (GFP) were constructed into the recombinant adeno-associated virus (rAAV). Swines were divided into 4 groups: rAAV-GFP group (6 swines), rAAV-CD151 group (6 swines), rAAV-antiCD151 group (6 swines) and control group (6 swines). The swines were performed with coronary artery ligation and intramuscularly injection with rAAV. Eight weeks after vector administration, western blot was used to detect gene expression of CD151. 13N-labeled NH3 positron emission tomography (PET) was used to evaluate myocardial perfusion. Echocardiography was used to assess myocardial function. Results Compared with the control group and the rAAV-GFP group, the rAAV-CD151 group showed higher CD151 protein expression. Compared with the rAAV-GFP group, the defect size of myocardium was decreased[( 11.3±2.4)% vs. (21.1±2.6)%, t= -5.67,P<0.01] and left ventricular ejection fraction (EF), left ventricular fractional shortening (FS), the ratio of anterior lateral wall thickening (△ALWT) and ratio of interventricular septum thickening (△IVST) were significantly improved in rAAV-CD151 group 8 weeks after vector administration [(65.7±4.6)% vs. (54.7±5.3)%, (36.0±2.9)% vs. (27.6±3.1)%,(55.4± 4.9)% vs. (36.8±7.8)%, (35.2±6.0)% vs. (26.7±4.4)%, t=3.98, 3.35, 3.34, 9.27, all P< 0.05]. The level of diastolic ALWT and diastolic IVST was also increased in rAAV CD151 group compared with rAAV-GFP group ( P<0.05).Compared with rAAV-CD151 group, parameters of myocardial function in rAAV-antisense CD151 group were not improved (P<0.05). Conclusions rAAV-CD151 can effectively transfeet the myocardium, increase the expression ofCD151 protein, promote the blood perfusion of myocardium and improve the ventricular function after myocardial infarction.

Objective To evaluate the efficacy of long-pulsed tunable Nd: YAG laser on capillary hemangioma and to analyse its influencial factors. Methods A retrospective review was conducted on 124 patients with 135 vascular lesions treated with long-pulsed tunable Nd:YAG laser from February, 2007 to January, 2008. Working parameters, including spot size (3-5 mm), pulse duration (10-30 ms) and fluence (120-200 J/cm2) were determined based on the size, color and depth of lesions and adjusted according to the immediate reaction of lesions. The interval of two treatments was 1 month. Results Of the 135 lesions, 100 experienced a more than 95% subsidence, 22 achieved 60%-94% subsidence, 11 got 30% -59% subsidence, and 2 reached less than 30% subsidence. The cure rate and effective rate were 74.07% and 90.37% respectively. Smaller lesions showed a better response to the treatment than larger ones (P<0.0001), whereas the sites and depth of lesions had no effect on the efficacy (both P>0.05). Atrophy scar occurred in 4 (2.96%) lesions, and blisters in 12 (8.89%) lesions after the treatment. No purpura or pigmentary changes occurred. Conclusion The long-pulsed tunable Nd:YAG laser is an effective treatmnt for capillary hemangioma with fast action and few side reactions.
