【Objective】 To analyze the serological characteristics of an anemia patient with cold autoantibodies and IgG anti S antibody. 【Methods】 Unexpected antibody screening was performed on screening cells, autologous cells and panel cells with patient serum in saline and anti human globulin card media at room temperature and 37 ℃, respectively. At the same time, the serum that destroying IgM antibodies and acid elution solution were respectively screened for unexpected antibodies in anti human globulin card media. The absorption-elution test was used to treat patients′ red blood cells and serum, and the unexpected antibody identification and cross matching were performed after excluding the interference of cold autoantibodies. 【Results】 Cold autoantibodies and IgG anti S antibody were found in the serum of this patient. 【Conclusion】 When a patient is found to have cold autoantibodies, it is necessary to screen the alloantibody, in order to avoid post transfusion immune reactions due to missed detection of alloantibody.

ObjectiveTo find out the problems and deficiencies in colposcopy through the quality control of colposcopy in 19 hospitals in Zibo City， so as to put forward constructive opinions and suggestion to improve the accuracy and standardization of colposcopy by the doctors in local hospitals. MethodsA total of 21 hospitals with colposcopy examination in Zibo City were selected as the research object. The quality control standards were formulated and the case data in the early stage were evaluated. Two hospitals had less than 10 cases completed each year and no on-site quality control.A total of 19 hospitals had on-site quality control with the operation process of colposcopy instrument on site， the configuration of colposcopy， the proportion of colposcopy examination reagents used in the department of pathology， and the operation period of colposcopy examination， as well as the on-site observation report. The qualified rate of each hospital were counted and analyzed. ResultsThe quality control results of 19 hospitals showed that the qualifications and the clinical practice of obstetrics and gynecology for more than 3 years reached 100.00%. Those who complete more than 100 new diagnosis cases each year and those who have been trained for more than 3 months are gradually increasing. The pathological specimens met the needs and the positive predictive value of high-grade squamous intraepithelial lesion was significantly improved in the quality evaluation indicators of colposcopy （all P<0.05）.In the basic elements of the colposcopy report， there were statistically significant differences in 5 aspects：adequacy of the examination， the description of specific images， the interpretation of key images， the diagnosis of the colposcopy， and the post-examination processing through 2 colposcopy quality control comparisons （all P<0.05）. ConclusionThe overall level of colposcopy in Zibo City has been significantly improved through the comparison of the quality control results of two colposcopy. We can improve the quality of colposcopy effectively through regular quality control.

This is an in vitro study to explore the effects of cryopreservation and resuscitation on the biological characteristics of osteoblasts at different times. Osteoblasts taken from the crania of newly born SD rats were cultured. Comparative studies were made on the cells' proliferation, the activity of alkaline phosphatase (ALP), and the number of live cells among fresh cultured osteoblasts and cells after the inception of cryopreservation and resuscitation at time-periods of one, three, six months respectively. The results showed that there were no significant differences among four groups in cell proliferation and in activity of ALP (P > 0.05). Yet, after cryopreservation and resuscitation, there were significant differences between the six-month group and the other three groups (P < 0.05). The results also showed, after cryopreservation and resuscitation, there were no significant differences between the control group and the one-month and three-month groups, respectively (P > 0.05). These findings indicated that the live cells might decrease in number after the osteoblasts were cryopreserved for too long a period, but after cryopreservation and resuscitation, the cells still retained the original biological characteristics of osteoblasts.

OBJECTIVE: To explore effect and significance of lateral closed high tibial osteotomy on recovery of activity of knee joint. METHODS: From February to December 2018, 78 patients with knee osteoarthritis who were treated by high tibial osteotomy for the first time were selected as the observation group, including 46 males and 32 females, aged from 55 to 73 years old with an average age of (61.78±6.39) years old, the course of disease ranged from 6 to 24 months with an average of (16.52±4.25) months;according to Kellgren-Lawrence (K-L) grading, 36 patients were gradeⅡand 42 patients were grade Ⅲ. Another 20 healthy people were selected as healthy group, including 13 males and 7 females, aged from 56 to 73 years old with an average of (60.89±7.12) years old. The expression of miR-146 in peripheral blood was compared between observation group and healthy group. At the same time, patients in observation group were followed up for 6 months. The patients whose knee joint function returned to normal or improved significantly during the follow-up period were admitted as the effective group, while the patients whose knee joint function did not improve significantly or tended to aggravate were admitted as the ineffective group. The clinical data and the relative expression of serum miR-146 between effective group and ineffective group were analyzed. RESULTS: The relative expression of serum miR-146 in observation group after operation was significantly higher than that in healthy group ( CONCLUSION The expression level of serum miR-146 showed upward trend, which could regulate the differentiation of chondrocyte. The monitoring of miR-146 after operation has reference value for predicting the recovery of bone and joint function after operation.

BACKGROUNDSleep deprivation (SD) has been used in treatment of depression disorder, and could effectively improve the patients' depressive symptoms.The aim of the study was to explore the effects of SD on electroencephalographic (EEG) and executive function changes in patients with depression.

METHODSEighteen depression patients (DPs) and 21 healthy controls (HCs) were enrolled in the present study. The whole night polysomnography (PSG) was recorded by Neurofax-1518K (Nihon Kohden, Japan) system before and after 36 hours of SD. The level of subjects' depression state was assessed by Visual Analogue Scale (VAS), and the executive function was assessed by Wisconsin Card Sorting Test (WCST).

RESULTSSignificantly decreased sleep latency (SL; before SD: (31.8 ± 11.1) minutes, after SD: (8.8 ± 5.2) minutes, P < 0.01) and REM sleep latency (RL; before SD: (79.8 ± 13.5) minutes, after SD: (62.9 ± 10.2) minutes, P < 0.01) were found after SD PSG in depression patients. Decreased Stage 1 (S1; before SD: (11.7 ± 2.9)%, after SD: (7.3 ± 1.1)%, P < 0.01) and Stage 2 (S2, before SD: (53.8 ± 15.5)%, after SD: (42.3 ± 14.7)%, P < 0.05) of non-rapid eye movement (NREM) sleep, and increased Stage 3 (S3, before SD: (11.8 ± 5.5)%, after SD: (23.6 ± 5.8)%, P < 0.01) and Stage 4 (S4, before SD: (8.8 ± 3.3)%, after SD: (27.4 ± 4.8)%, P < 0.01) NREM sleep were also found. After SD, the depression level in patients decreased from 6.7 ± 2.1 to 2.9 ± 0.7 (P < 0.01). In WCST, the patients showed significantly decreased Response errors (Re, before SD: 22.3 ± 2.4, after SD: 18.3 ± 2.7, P < 0.01) and Response preservative errors (Rpe, before SD: 11.6 ± 3.6, after SD: 9.3 ± 2.9, P < 0.05). Depression patients' RE (t = 2.17, P < 0.05) and Rpe (t = 2.96, P < 0.01) also decreased significantly compared to healthy controls.

CONCLUSIONSD can improve depression symptom and executive function in depression patients.

Curcumin, which is extracted from the plant Curcuma longa, has been used in the therapeutic arsenal for clinical oncology. Curcumin has chemopreventive and antitumoral activities against some aggressive and recurrent cancers. The expressions and activities of various proteins, such as inflammatory cytokines and enzymes, transcription factors, and gene-products linked with cell survivals and proliferation, can be modified by curcumin. Moreover, curcumin decreases the toxic effect of mitomycin C. Though curcumin has shown highly cytotoxic to some cancer cell lines, curcumin is insoluble and instable in water. The solubility of curcumin could be enhanced by utilizing the solubilizing properties of rubusoside. In addition, the selective delivery of synthetic analogs or nanotechnology-based formulations of curcumin to tumors may improve the chemopreventive and chemotherapeutic effects. The focus of this short review is to describe how curcumin participates in antitumor processes in breast cancer cells.

BACKGROUNDImmune-related hematocytopenia (IRH) is considered to be related with the production of autoantibody, as well as the activation of humoral immunity which is stimulated by B lymphocyte. This study aimed to observe the levels of various cytokines in the blood serum and the in situ active state of macrophage (Mφ) in the medullary hematopoietic microenvironment of IRH patients, and to probe into the immune mechanism and clinical significance of Mφ in hematopoietic cell injury.

METHODSELISA is used to detect the IL-4, IL-6, IL-12, IL-17, and IFN-γ levels in the peripheral blood serum of 376 patients in pre- and post-therapy. Cytochemistry and cell immunochemistry methods are used to observe the peroxidase (POX), nonspecific esterase (NSE), hemosiderin granules, and HLA-DR activity of Mφ in the bone marrow of patients. Immunofluorescence is used to observe the expression of hemocyte antihuman globulin IgG antibody, lymphocytes CD4 molecule, Mφ membrane FcγIIreceptor (FcγIIR), mannitose receptor (MR), IFN-γ, ICAM-1, IL-12, and IL-17A and the formation mechanism of antibody-dependent cell-mediated cytotoxicity (ADCC) hematopoietic cell islands (HI) in the medullary hematopoietic microenvironment of patients. Glucocorticoid is used for treatment on the basis of anti-infection therapy, and gamma globulin stoss therapy is used for the appearance of ADCC-type HI or serious Mφ bloodthirsty phenomenon; if necessary, association of Cyclosporine A (CsA) should be used and chalybeate should be supplemented.

RESULTSIn the patient group, the levels of IL-4, IL-6, IL-12, IL-17, and IFN-γ were increased. After treatment, the cytokine levels gradually became normal. The activated Mφ in the marrow highly expressed NSE and POX, and Mφ swallowed more hemosiderin particles, but the iron in the cytoplasm of immature erythrocytes decreased. The activated Mφ expressed HLA-DR, MR, ICAM-1, IFN-γ, and IL-12. For patients with humoral immunity activation and bacterial infection, Mφ weakly expressed IL-17A but highly expressed FcγIIR, and the phenomenon that ADCC-type HI broke pathological blood corpuscles often occurred; for the cellular immune activation along with virus infection, the white blood count (WBC) significantly reduced, Mφ weakly expressed FcγIIR, secretory highly expressed IL-17A, and the phenomena that Mφ adhered to, captured and swallowed blood cell often occurred. After four weeks of anti-infective and immunosuppressive therapy, nuclear apoptosis of Mφ occurred in the bone marrow of patients, HI and bloodthirsty phenomenon disappeared, and the peripheral blood picture started to improve.

CONCLUSIONSMφ is an important antigen presenting cell in the IRH marrow for hematopoiesis destruction and an immune effector cell of hematopoietic injury; infection can promote the activation of Mφ, upregulate the impression of immune molecule and receptors, form ADCC HI, aggravate hematopoietic injury, and accelerate the destruction on hematopoietic cell.
