Swabbing samples were routinely collected from health care workers ( HCW) contacting newborns in Obstetrics Department of our hospital on every Wednesday during January to December 2015. Total 495 samples from nasal vestibule and 483 samples from hands of HCW were collected for bacterial culture.The carrying status of methicillin-resistant staphylococccus aureus ( MRSA) was analyzed.The results showed that the average carrying rate of MRSA in the nasal vestibule was 8.1%(40/495) and that in hands was 5.0(24/483)(χ2 =3.871, P<0.05).The MRSA detection rate of nasal vestibular samples in the second quarter was the highest [12.2%(17/139)], while that of hands samples was highest in the first quarter [ 15.3%( 15/98 ) ] . The study indicates that carrying rate of MRSA in health care workers contacting newborns of our hospital is high , and the training and monitoring should be strengthened among health workers to reduce the MRSA carrying rate .

Objective To investigate the clinical effect and safety of surgical treatment for severe, refractory hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods Patients with severe HC, who were admitted to Peking University Institute of Hematology from January 2010 to December 2015, were enrolled in this study.All patients were refractory to medical managements and received bladder surgery including mucous electrocoagulation and/or selective transcatheter arterial embolization.Results A total of 17 patients with severe HC (grade Ⅲ, n=5;grade Ⅳ, n=12) received surgical treatment, including 11 embolization and 18 mucous electrocoagulation.The median time from allo-HSCT to surgery was 107 d (46-179 d) and 75 d after HC.Eight patients only received embolization.Four patients only received mucous electrocoagulation.Five patients were given combined embolization and electrocoagulation.HC was cured in 11 patients, improved in 1 patient, which corresponded to a response rate of 70.6% and complete remission rate of 64.7%.Five patients didn′t respond to these methods.In patients with response, macroscopic hematuria disappeared 3 to 10 days after treatments whereas microscopic hematuria vanished after 25 to 32 days.Both procedures were well tolerated and no severe adverse effects were observed.Conclusion Surgery of bladder mucous electrocoagulation and/or selective arterial embolization are safe and effective for severe HC.

Objective To explore the incidence, diagnosis and treatment of nephrotic syndrome ( NS ) following allogeneic hematopoietic stem cell transplantation ( allo-HSCT) in one single center.Methods Analysis were carried out based on the records of 1464 patients following allo-HSCT hospitalized in Peking University People's Hospital from January 1996 to April 2009, so as to evaluate the incidence and outcomes of NS. A total of 1464 patients whose survival time was longer than 100 d were enrolled. Eight patients (0.6%) had NS following allo-HSCT. Using the nested case-controlled study, 56 cases who received transplantation within the same period were selected as control group for risk factors analysis. Results The median time of NS was 488(54-1185)d after allo-HSCT. Lower extremities' edema and heavy proteinuria were present in all the patients. Two patients were accompanied with impaired renal function. Six patients suffered from chronic graft-versus-host disease (GVHD). Three patients with NS were accompanied with other symptoms of GVHD. Renal biopsy examination showed typical features of minimal change diseases in 3 patients and membranous nephropathy in 1 patient. All cases achieved complete remission (CR) after taking combined immunosuppressant agents. One patient relapsed soon after all the immunosuppressant agents were stopped. Six patients were still surviving with disease free. One patient died of the relapse of leukemia and another patient died of early discharge from hospital after allo-HSCT. The possible factors correlated with the occurrence of NS were analyzed, and the occurrence of chronic GVHD was identified as an independent factor of NS. Conclusions NS should be carefully taken into consideration when edema and proteinuria are present in patients following allo-HSCT. The occurrence of NS is probably related with chronic GVHD. NS responds well to immunosuppressant agents.

Total 1 452 newborns were home visited within 28 d after birth during January 2016 to December 2016,and 27 cases of skin infections were found.Umbilical inflammation was more common (11 cases),followed by folliculitis (9 cases) and impetigo (7 cases).Samples were collected for bacterial culture and identification from the skin of infected newborns,the hands and nasal cavity of family baby caretakers,and household articles,including faucets,mobile phones,toilet buttons and so on.The pathogens identified were Staphylococcus aureus in 20 cases (including 2 methicillin-resistant strains) and Escherichia coli in 7 cases.The isolation of Staphylococcus aureus in household articles was significantly correlated with newborns infected with Staphylococcus aureus (x2=678.808,P＜0.01);and the isolation of Staphylococcus aureus from family baby caretakers was also significantly associated with neonatal Staphylococcus aureus infection (x2=820.396,P＜0.01).In 7 cases of Escherichia coli infection,the Escherichia coli were detected from samples of baby caretakers or household articles.The study suggests that the awareness of baby caretakers and home hygiene are important to reduce neonatal skin infections.

Objective To investigate the risk factors and prognosis of transplant-associated thrombotic microangiopathy (TA-TMA) following acute graft-versus-host disease (aGVHD),and to evaluate the factors that might influence the prognosis of TA-TMA.Methods A nested case-control study was designed.Cases with TA-TMA (n =33) and controls (n =77) matched for age at allogeneic hematopoietic stem cell transplantation (allo-HSCT) and length of follow-up were identified from a cohort of 356 patients who suffered from aGVHD after allo-HSCT between 2009 and 2011.Results The median time to presentation of TA-TMA was 3.5 (1.2-23.0) months post-HSCT.The median time from diagnosis and first-line treatment failure of aGVHD to TA-TMA diagnosis was 25 (7-257) days and 15 (5-257) days,respectively.aGVHD occurring beyond 60 days after allo-HSCT,initial grade Ⅲ-Ⅳ aGVHD,first-line treatment failure and receiving tacrolimus as second-line treatment were independently associated with the occurrence of TA-TMA,and patients with two or more risk factors were at higher risk (OR =210.0,P =0.000).Twenty-two (66.7％) TA-TMA patients died.Progressive TA-TMA was the significantly adverse factor affccting the survival of TA-TMA cases.None of therapies could improve prognosis of patients with TA-TMA.Conclusion Many characteristics of aGVHD were associated with TA-TMA,which help us to identify the individuals who are at higher risk of developing TA-TMA following aGVHD and to select the more reasonable GVHD therapeutic strategies.

Objective:To investigate the clinicopathological characteristics and survival of patients with lymphoplasmacytic lymphoma (LPL).Methods:The data of 33 newly diagnosed LPL patients in the First Affiliated Hospital of Dalian Medical University from July 2003 to May 2021 were retrospectively analyzed. The clinical characteristics, bone marrow cell morphology, immunophenotyping, chromosomal karyotype, gene mutation, treatment response and prognosis were analyzed, and Kaplan-Meier method was used to analyze the survival of patients.Results:The median age of onset of 33 patients was 66 years old (55-84 years old). There were 26 males (78.8%) and 7 females (21.2%). The common clinical manifestations were anemia (31 cases, 93.9%), enlarged lymph nodes (16 cases, 48.5%) and B symptoms (8 cases, 24.2%). All patients had bone marrow involvement and M protein, 23 of them (69.7%) were type IgM-κ, 8 cases (24.2%) were type IgM-λ, 1 case (3.0%) was type IgG-κ, and 1 case (3.0%) was type IgA-κ. Lymphocytes, lymphoplasmacytes or plasma cells was increased in bone marrow smear; 22 patients underwent immunophenotyping of bone marrow by flow cytometry, and all patients expressed B cell surface antigens (CD19 and CD20), 16 patients (72.7%) lost the expression of CD5 and CD10, 13 patients (59.1%) expressed or weakly expressed CD138 and 5 patients (22.7%) expressed CD38. Seven out of 23 cases (30.4%) who received chromosome examination had abnormal chromosomal karyotype. Fourteen out of 16 cases (87.5%) who received MYD88 L265P mutation detection harbored the mutation. Among 21 patients with evaluable efficacy, 18 patients (85.7%) responded to treatment, achieving partial remission or stable disease, but the rate of complete remission was low (14.3%, 3/21). The median follow-up time was 34 months (2-102 months), 1 case was lost. The median overall survival time was not reached, and the 3-year and 5-year overall survival rates were 79.2% and 67.9%, respectively.Conclusions:LPL is a rare indolent small B-cell lymphoma with a long course and a variety of manifestations, which is commonly seen in elderly men.Serological examination, bone marrow cell morphology and biopsy, immunophenotyping and MYD88 L265P mutation detection are important for the diagnosis and differential diagnosis.

Hypoprothrombinemia-lupus anticoagulant syndrome(HLAS)is a rare disease in which patients present with varying degrees of bleeding and positive lupus anticoagulant with reduced prothrombin on laboratory tests.This article reports a case of HLAS in a middle-aged woman with recurrent gingival bleeding and epistaxis as the first presentation.After admission,tests revealed prolonged prothrombin time(PT),activated partial thromboplastin time(APTT),and reduced coagulation factor Ⅱ activity,and positive lupus anticoagulant(LA).Meanwhile,the patient had symptoms of dry mouth and dry eyes for a long time,and the examination of autoantibodies,tear secretion test and salivary gland emission computed tomography(ECT)were consistent with the diagnosis of Sjogren's syndrome.The final diagnosis was HLAS secondary to Sjogren's syndrome.After treatment with methylprednisolone and cyclophosphamide,the coagulation disorder gradually improved,and no recurrent bleeding occurred.HLAS is a rare clinical case,which reminds medical staff to be alert to the possibility of HLAS when encountering patients with unexplained prolonged APTT and PT and positive lupus anticoagulant.

In order to study the chemical constituents of the leaves of Tripterygium wilfordii and provide references for the bio-active study, we isolated nine compounds from the dried leaves of Tripterygium wilfordii. Their structures were determined by application of spectroscopic (NMR, MS) and chemical methods. These compounds were isolated and identified as (+)-lyoniresinol (1), (+)-isolariciresinol (2), burselignan (3), dibutyl phthalate (4), cyclo-(S-Pro-R-Phe) (5), cyclo-(S-Pro-R-Leu) (6), cyclo-(S-Pro-S-Ile) (7), 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (8) and daucosterol (9).

Objective To investigate the safety and efficacy of second allogeneic hematopoietic stem cell transplantation for the relapsed hematologic malignancies. Methods The data of 25 relapsed patients received the second allogeneic transplantation as a salvage therapy in Institute of Hematology Peking University between October 1999 and March 2010 were analyzed retrospectively. Twenty-four patients relapsed at 8. 8 (1-55) months after the first transplantation, except one received the second transplantation as prophylaxis therapy. They received the second transplantation after 3(0. 3-20) months' therapy. The median time between the 2 transplants was 10. 6(0. 6-59. 0) months. Results Most of the patients were given the conditioning regimen including total body irradiation (TBI, 700-779 cGy) or modified busulfan and cyclophosphamide (BUCY, BU 12 mg). All patients survived more than 30 days and achieved sustained white blood cell engraftment. Sinus obstructive syndrome, irradiation dermatitis and acute myocardial infraction were occurred in 3 patients and recoverable. Until January 31 in 2011, with a median observation period of 9. 1 (2. 0-131. 1) months, 8 patients had been living with a overall survival (OS) of 30.9%.Twelve patients relapsed at a median 4. 4 months and 10 died of it. The other 7 patients died of transplant related complications. The non-relapsed mortality was 35. 1 %. The disease status at the 2nd transplantation was the only factor which effected the OS (P = 0. 009). Conclusions The second allogeneic transplantation is a viable option for patients relapsing after the first transplantation. Reduced intensive conditioning regimen ensures the graft engraftment and reduces transplant related toxicity.
