Objective To investigate the effects of ultrasound irradiating hydroxycamptothecin (HCPT)-loaded microbubbles on apoptosis in human hepatoma SMMC-7721 cells, and to clarify its probable mechanism. Methods The SMMC-7721 cells were randomly divided into six groups as follows: control group, blank liposome microbubbles plus ultrasound, HCPT-loaded microbubbles, HCPT, HCPT plus ultrasound,and HCPT-loaded microbubbles plus ultrasound. Apoptosis was ascertained by Annexin V-Fire/ PI and TUNEL methods. The expression of Bcl-2 and Bax protein was detected by immunocytochemistry staining technique. Results In the group of HCPT-loaded microbubbles plus ultrasound,the apoptosis rate at early term was found to reach (12.18 ± 1.38)% by Annexin V-Fitc/PI assay, brown-colored positive apoptotic cells were observed and the apoptosis rate at advanced term was found to reach (34.25 ± 1.83)% with TUNEL method. The expression of Bcl-2 was found to decrease,the expression of Bax increase,and the ratio of Bcl-2/bax significantly decrease by immunocytochemistry staining technique in the same group. Differences with other groups were significant. Conclusions The method of ultrasound irradiating HCPT-loaded microbubbles can notability induce human hepatoma SMMC-7721 cells apoptosis. The decrease in the ratio of Bcl-2 to Bax might be responsible for cells apoptosis.

There are a lot of feasibility studies, using sentinel lymph node biopsy SLNB instead of Alex lymph node dissection (ALND), having got a conseusus that SLNB is a safe and useful method in the treatment of breast cancer. But in clinical practice, there are much false negative rate (FNR) which need to be carefully dealt with for SLNB. In order to diminish the FNR, how many nodes should be the perfect number to lower the FNR? If positive detection was found in the SLN, should ALND always be needed? And when micro metastasis was found in the post operation HE staining? Does it need further treatment? We make a review to discuss those matters.

6.Research progress on the function of macrophages in preterm delivery
Journal of Chinese Physician 2023;25(9):1294-1300
Premature birth is one of the main challenges faced by modern obstetrics, and there is still a lack of effective treatment methods. The successful pregnancy process depends on the immune balance at the maternal fetal interface, and due to the unique antigen presenting molecules and immune recognition receptors on the surface of macrophages, they play a crucial role in maternal fetal immune tolerance. The dysfunction of uterine macrophages can lead to various adverse pregnancy outcomes. This review summarizes the latest research progress on the origin of macrophages, their specialization in the uterine microenvironment, their physiological functions at different stages of pregnancy, and their role in preterm delivery.

OBJECTIVE:
To detect the expression of miR-126 in different tissues and organs and the change of peripheral blood glucose in microRNA-126 knock down (miR-126 KD) mouse, and to explore the pathological significance.
METHODS:
Total RNAs were isolated from twelve kinds of tissues and organs in wild-type mouse (WT) and miR-126 KD mouse respectively. Th en, the expression level of miR-126 was detected by real-time PCR assay. Th e levels of peripheral blood glucose and body weight of miR-126 KD mice were measured. Th e pathologic changes of pancreas and lung tissue were observed by HE staining.
RESULTS:
Compared with the WT mice, the relative expression of miR-126 in spleen, liver, muscle and lung from the miR-126 KD mice were dramatically decreased respectively (P<0.05). The level of peripheral blood glucose in the miR-126 KD mouse increased significantly at seven week and sixteen week after the birth (P<0.05). HE staining showed that the pathological structure of pancreas and liver were abnormal. The body weight of miR-126 KD mice was increased obviously from thirteen week after birth (P<0.05).
CONCLUSION
Peripheral blood glucose levels in the miR-126 KD mouse were dramatically elevated, which might be related to the pathological changes in the structure of pancreas and liver. These results suggest that miR-126 may play an important role in the metabolism of blood glucose and the development of type 2 diabetes mellitus.

OBJECTIVE:
To study the pathologic characteristics of bone marrow for CD5 positive small B cell lymphoma (SBL).
METHODS:
The pathologic profiles of 92 patients with CD5 positive SBL were retrospectively analyzed. The morphologic and immunophenotypic features were analyzed by flow cytometry and immunohistochemistry. IgH/CCND1 was examined by fluorescence in situ hybridization (FISH).
RESULTS:
A total of 92 patients with CD5 positive SBL were enrolled in this study, including 56 (60.9%) chronic lymphocytic leukemia /small lymphocytic lymphoma (CLL/SLL), 23 (25.0%) mantle cell lymphoma (MCL) and 13 other SBL (14.1%). Among the 13 other cases, 5, 4 and 4 cases were follicular lymphoma (FL), lymphoplasmacytic lymphoma (LPL) and splenic marginal zone lymphoma (SMZL), respectively. The frequency of patterns for bone marrow infiltration was as follow: diffuse pattern (19/92), mixed pattern (15/92), nodular pattern (9/92), interstitial pattern (8/92), and intrasinusodial pattern (2/92). All patients expressed CD19, CD20 and CD5. According to the immunophenotypic score system, all the CLL patients had 4-5 scores, while SMCL and other SBL patients had less than 3 scores. For the other SBL patients, 5 FL expressed CD10, while 3 FL, 1 LPL and 3 SMZL expressed CD23. There was a significant difference in the expression of CD23, sIgM, FMC7, CD11C and CD22 between the CLL and MCL groups (P<0.01). All 23 MCL patients expressed cyclin D1 and showed IgH/CCND1 gene translocation by FISH detection.
CONCLUSION
CD5 positive SBL includes a variety of types of lymphoma. Patterns of bone marrow for CD5 positive SBL are diversity. Immunophenotypic analysis by flow cytometry is essential in the diagnosis and differential diagnosis of CD5 positive SBL, especially for CLL.
