ObjectiveTo investigate and analyze case reporting ethical review and patient informed consent reports published in the comprehensive journals of clinical medicine in China in 2022. MethodsAccording to the data from the 2022 Edition of the Chinese Science and Technology Journal of the Citation Reports （Extended Version），the case reports published in comprehensive journals of clinical medicine in 2022 were selected as the research objects.The information on ethics and patient informed consent was extracted from the case reports that met the selection criteria，and Microsoft Excel 2021 and SPSS 21.0 were used to sort out and analyze the data. ResultsA total of 587 case reporting articles were published in the 42 included journals in 2022，of which 36 （6.13%） reported on science and technology ethics and/or informed consent.Case reports reporting on science and technology ethics and/or informed consent mostly came from the key magazine of China technology （88.89% Vs.65.88%），and the proportion of manuscripts involving science and technology ethics on the official website of the journal was relatively high （86.11% Vs.63.88%），and the difference was statistically significant （P<0.01）. ConclusionThe proportion of case reports of science and technology ethics and/or informed consent in journals of comprehensive discipline classification of clinical medicine was relatively low.Currently，most international journals are required to obtain the informed consent of patients or legal guardians before publishing case reports.Compared with this，there are still certain gaps in China，which need to be paid great attention to.

OBJECTIVETo probe in the possible acting mechanism of Bizhongxiao Decoction (BZXD) for treatment of early active rheumatoid arthritis (RA) by way of observing the two-dimensional gel electrophoresis map of proteins in peripheral blood mononuclear cells (PBMCs) of healthy persons and RA patients (intervened or un-intervened with BZXD), analyzing the differential proteins and seeking out the RA associated proteins.

METHODSEighteen patients with early active RA were randomized into the BZXD group and the methotrexate (MTX) group, nine in each group, they were treated with BZXD (contained 15 Chinese herbs, as Herba Hedyotis diffusae, Herba Sarcandrae glabrae, Radix Salviae miltiorrhizae, Caulis Trachelosperi, Rhizoma Drynariae, Semen Coicis, etc.) and MTX combined with nimesulide Tablets respectively, three months as a treatment course, and their blood samples were collected for observation. Besides, blood samples from 9 healthy persons were taken as normal controls. PBMCs were isolated from blood using lymphozytes separation medium, and total protein in the cells was extracted through immobilized pH gradient two-dimensional gel electrophoresis. After Coomassie brilliant blue G250 staining, gel-image analysis was performed using PDQuest software. The differentially expressed proteins were identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS). Then partial proteins were validated by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSThe 2-DE protein profile of PBMCs from healthy persons and RA patients before and 3 months after treatment were obtained, and 23 differential protein spots were found, 14 from 18 differential protein spots were successfully identified, of which 8 proteins were up-regulated and 6 proteins were down-regulated in RA patients as compared with control. After 3-month treatment, 5 differentially expressed proteins showed more obvious in the BZXD group than in the MTX group. RT-PCR verified that the expression of ApoA-I in all the three groups was consistent with the outcomes of 2-DE.

CONCLUSIONSSome differentially expressed proteins exist in the PBMCs of RA patients, which may play a potential role in the pathogenesis of RA; BZXD may treat RA by way of regulating the expression of some differential proteins in patients.

OBJECTIVE: To analyze the change of serum C1q in the course of multiple myeloma (MM) and its correlation with clinical characteristics. METHODS: A total of 138 newly diagnosed MM patients in Zhongnan Hospital of Wuhan University from June 2016 to December 2019 were selected as research objects, during the same period 50 age-matched anemia patients, 50 lymphoma patients, 50 leukemia patients, and 50 myelodysplastic syndrome (MDS) patients were selected as control groups. All the patients met WHO disease classification, and were definitely diagnosed by pathology or bone marrow smear/biopsy. The changes of C1q between MM patients and control group, as well as in different therapeutic responses of MM patients before and after treatment were compared, also the difference of clinical characteristics among MM patients with different C1q level, so as to analyze risk factors which led to C1q decline. RESULTS: The average value of C1q in MM patients was (128.18±51.24) mg/L, which was significantly lower than control group (P<0.01). The levels of white blood cell, platelet (PLT), hemoglobin (Hb), serum calcium, albumin, lactate dehydrogenase (LDH) in newly diagnosed high C1q group were significantly higher than those in low C1q group (P<0.05). Logistic analysis showed that the levels of PLT, Hb, albumin, and LDH in newly diagnosed high C1q group were higher than those in low C1q group (r=0.248, r=0.394, r=0.405, r=0.295). After treatment, the levels of C1q in MM patients with complete remission and very good partial remission were significantly higher than before treatment (P<0.05), while those with partial remission and stable disease also increased but not significantly (P>0.05). CONCLUSION The C1q level in MM patients is significantly lower than that in patients with other hematologic system diseases, and it increases with the remission of the disease after treatment.

Objective: To analysis the manifestations of chest CT imaging in acquired immunodeficiency syndrome (AIDS) patients complicated with pulmonary cryptococcosis. Methods: The clinical data of 72 AIDS patients complicated with pulmonary cryptococcosis were analyzed retrospectively. There were 3 cases (4.2%) diagnosed with pulmonary cryptococcosis by biopsy, including 1 case of pulmonary cryptococcosis and 2 cases of disseminated cryptococcosis; 69 cases (95.8%) with pulmonary manifestations and clinically diagnosed with pulmonary cryptococcosis, including 43 cases of cryptococcal meningitis and 26 cases of disseminated cryptococcosis. The imaging features of chest CT, in terms of the morphology, size, number, distribution, internal features and margins of the lesions were analyzed. Results: The chest CT findings were solid nodules or mass in 49 cases (68.1%), patchy shadows in 40 cases (55.6%), cavitary nodules or mass in 10 cases (13.9%), mediastinal and hilar lymph node enlargement in 17 cases (23.6%) and pleural effusion in 10 cases (13.9%). Conclusion The chest CT findings of AIDS patients complicated with pulmonary cryptococcosis mainly are multiple solid nodules or masses, patchy shadows and solitary cavitary pulmonary nodules or mass. For early diagnosis and treatment, cryptococcus screening should be performed in HIV-infected patients with pulmonary nodules or mass on chest CT.

OBJECTIVETo investigate the epidemiologic features of disseminated histoplasmosis (PDH) in Hubei province.

METHODSBone marrow smears of 12 patients diagnosed as Kala-azer in Hubei province including 4 patients in Jingsan, 2 patients in Shashi and each 1 in Yichang, Jinmen, Zhongxiang, Luotian, Xianning and Guanghua respectively were re-examed under microscope. Peripheral blood and bone marrow smears of several patients were detected. After inoculated the bone marrow, peripheral blood, liver and spleen tissue of patients in MLI, the single colony was trans-inoculated in BHIB, SDA and CMA and incubated at 25 degrees C and 35 degrees C. Bone marrow, peripheral blood and bacterial fluid of yeast-phase Histoplasma capsulatum (H.cap) were injected into the abdominal cavity of Kunming mice and nude mice. When symptoms and signs developed, the spleen tissue was separated, then observed under microscope and cultured. Mycelium-phase and Yeast-phase H.cap were inoculated in urase and gelatin medium, then incubated at 25 degrees C and 35 degrees C. Histoplasmin was injected subcutaneously into patients, and then followed for 48 - 72 hours. Amphotericin B was selected to treat the PDH patients.

RESULTSMoriform cell cluster and sausage-shaped cell were not observed in mononuclear-macrophages in the bone marrow smears from 12 patients. Leishman-Donovan body was found only in one patient. There wasn't kinetoplast in the cellular plasm of spores in 11 patients and no transeptae was found. The reaction of H.cap to urease was positive and H.cap did not liquefy the gelatin. It appeared to be mycelium-phase at 25 degrees C but no penicillus and catenulate conidia was found. The characteristic denticle macroconidia was observed but produced red coloring matter. It also appeared to be yeast-phase at 35 degrees C. Yeast-phase spores were observed under microscope. No sausage-shaped spore and transeptae were identified. H.cap could be acquired in the spleen tissue in Kunming mice and nude mice. Bacterium forms, characteristics under microscope and biochemical reaction of mycelium-phase and yeast-phase H.cap were different from some other kinds of dimorphic fungi such as Penicillium marneffei and Histoplasm duboisii etc.

CONCLUSIONThere were scattered epidemics of PDH in Hubei province. The detection rate of PDH was higher in the southeast area then in the northwest area. The golden standards of clinic diagnosis were mycological culture and inoculation to animals. Amphotericin B was necommended as the first choice for treatment.

OBJECTIVETo study the expression of NFkappaB p65 and its target genes in intestinal metaplasia (IM), dysplasia (Dys), gastric cancer (GC) infected with Helicobacter pylori (Hp) and explore the mechanism of infection by cytotoxin-associated antigen A expressing Hp (CagA(+)Hp) in the development of gastric cancer.

METHODSCagA antibody in blood sample of 289 patients was determined by ELISA. Hp was detected by rapid urease test and Warthin starry staining. Expression of NFkappaB p65 and its target genes in IM, Dys and GC was examined by immunohistochemistry.

RESULTSIn IMI approximately II, IMIII, DysI, DysII approximately III and GC, the expression of NFkappaB p65 was significantly higher in patients with CagA(+)Hp infection than those without CagA Hp infection. In IMIII and DysII approximately III, the expression of NFkappaB p65, c-myc, CyclinD(1) and bcl-xl was significantly higher in patients with CagA Hp infection than those without CagA Hp infection. In gastric cancer infected with CagA(+)Hp, the expression of NFkappaB p65, c-myc, CyclinD(1) and bcl-xl was significantly higher in intestinal type than in diffuse type.

CONCLUSIONThere are different mechanisms in intestinal type and diffuse type in the development of gastric cancer. The occurrence of intestinal type gastric cancer is associated with CagA(+)Hp infection which by NFkappaB p65 upregulating the expression of c-myc, CyclinD(1),bcl-xl in patients with IMIII, DysII approximately III. It may be an effective method to prevent gastric cancer by inhibiting NFkappaB p65.

OBJECTIVETo estimate prevalence of HIV/AIDS among children and the transmission routes in a highly endemic villages of AIDS.

METHODSTotally 208 high-risk women of child bearing age and 159 of their children aged 0 - 14 years were investigated. Their medical histories of blood donation or transfusion were collected, blood samples were taken and sera were separated for HIV test. Enzyme-linked immunosorbent assay (ELISA) and Western blot assay were performed for HIV antibody. The Nested-polymerase chain reaction (PCR) assay amplifying gag gene p17 was performed on samples of children aged less than 18 months.

RESULTSThirty-seven HIV infected cases were found among 159 children aged 0 - 14 years of whom 33 were infected by mother-to-child transmission (89.2%, 33/37), 3 by blood transfusion (8.1%, 3/37) and one by iatrogenic route (2.7%, 1/37). Sixty seven mothers who were seropositive for HIV and their 86 children who were born after 1992 were investigated, 33 cases of them were infected with HIV. The rate of vertical transmission was 38.4% (33/86). The HIV vertical transmission rate among mothers with AIDS (68.8%, 22/32) was significantly greater than that among mothers with asymptomatic HIV infection (20.4%, 11/54, P < 0.05). The number of children infected with HIV through vertical transmission increased from 1993 to 2001. Among 37 children infected with HIV, 12 cases developed AIDS and 4 of them died, of whom 2 cases died from tuberculosis. The morbidity of AIDS was 27.3% (9/33). Ninety three point nine percent (31/33) of infected mothers didn't know their HIV seropositive status before pregnancy and delivery. Of 8 pregnant women infected with HIV, one had aggravation of AIDS, 2 miscarried, 2 terminated their pregnancy and 3 continued their pregnancy.

CONCLUSIONMother-to-child transmission of HIV was the major route of HIV/AIDS transmission to the children. The main reason leading to HIV infection in children was the lack of prenatal HIV counseling and testing for the high-risk women of childbearing age and lake of interventions. The countermeasures must be taken to control the further transmission of AIDS in order to protect the health of women and children in the highly endemic areas of AIDS.

OBJECTIVETo explore the possible negative regulatory elements induced by the treatment of experimental murine hepatoma with 4-1BBL, and to investigate the synergistic effects and mechanisms of 4-1BBL and soluble PD-1 (sPD-1) in tumor therapy.

METHODSMice were inoculated intramuscularly (i.m.) with 5 x 10(5) H22 tumor cells in the right hind thigh to establish the experimental hepatoma model. The mice were randomly divided into 5 groups (12 mice in each group) after inoculation. The mice of group A, B, C and D were injected with NS, plasmid pcDNA3.1, plasmid p4-1BBL and plasmid pPD-1A respectively. The mice in group E, the combinatorial treatment group, were injected with plasmid p4-1BBL and pPD-1A together. Then the anti-tumor effects, using the tumor growth rates and mice survival rates and others as parameters, were recorded. Meanwhile, the phenotype of lymphocytes and residual tumor cells in the peri-tumor tissue were analyzed.

RESULTSEither transfection with 4-1BBL gene alone or with sPD-1 alone could inhibit tumor growth to some extent, but a more significant anticancer effect was obtained in the combinatorial treatment group (group E), in which the tumors were completely inhibited in 42% of the mice, compared with 0 in the other groups. In addition, the survival rate of mice in group E was 100%, compared with 30% in group B, 65% in group C and 62% in group D. The FACS analysis results showed that the expression level of B7-H1 and B7-DC on residual tumor cells in group C (injected with p4-1BBL alone) was higher than that on cells in other groups. The amount of CD8+ T cells in the peri-tumor tissue of group E was significantly increased.

CONCLUSION4-1BBl can induce an up-regulation of negative regulatory elements and at the same time it can enhance the anti-tumor response. The combinatorial treatment with 4-1BBL and sPD-1 can produce a positive synergistic anti-tumor effect on our murine experimental hepatoma.

Objective: To analyze the clinical characteristics, pathological features and survival of patients with AIDS related non-Hodgkin’s lymphoma (ARL) . Methods: The clinical data of 53 ARL cases diagnosed and received care at Zhongnan hospital of Wuhan University were retrospectively studied, and 106 controls were enrolled as control group according to 1∶2 for paired cases and control. SPSS 13.0 package was used for statistical analysis. Kaplan-Meier was applied to assess the survival probability. Results: The mean age of patients with ARL was 43 (11-67) years. Male versus female was approximately 4∶1. The median CD4⁺ T cell count was (146±20) /ml. The Ann Arbor clinical classification showed that 52.8% of the cases were of stage Ⅲ and Ⅳ. Approximately 54.7% of the patients had elevated serum lactate dehydrogenase (LDH) . According to international prognosis index score, 64.2% of the patients were in high risk group. Diffuse large B-cell lymphoma (DLBCL) was the predominant histological subtype. Among 53 cases, 33 cases (62.3%) received combination of anti-HIV therapy and anti-NHL (CHOP) chemotherapy regimen, 8 cases (15.1%) only received anti-HIV therapy, and 12 cases (22.6%) asked for alleviative treatment. Median survival time was (6.0±1.3) months for ARL cases versus (48.0±10.0) months for controls (P<0.05) . After eliminating cases who did not receive anti-lymphoma treatment, ARL cases showed a lower 1-year OS rates than control group (60.6% versus 83.0%) , but no difference about 2-, 3- and 5-year OS rates (53.5% versus 60.5%, 48.1% versus 45.9%, and 39.1% versus 27.5%, respectively) . Conclusions ARL is more common in young adults; one-year mortality rate is high. Anti-HIV therapy combined with anti-NHL therapy could significantly improve the prognosis of ARL patients. CHOP regimen may be more suitable for ARL patients.
