Progress in application of adult endogenous neurogenesis in brain injury repair / 生理学报

Persistent neurogenesis exists in the subventricular zone (SVZ) of the ventricles and the subgranular zone (SGZ) of the dentate gyrus of the hippocampus in the adult mammalian brain. Adult endogenous neurogenesis not only plays an important role in the normal brain function, but also has important significance in the repair and treatment of brain injury or brain diseases. This article reviews the process of adult endogenous neurogenesis and its application in the repair of traumatic brain injury (TBI) or ischemic stroke, and discusses the strategies of activating adult endogenous neurogenesis to repair brain injury and its practical significance in promoting functional recovery after brain injury.

8-Azaguanine-induced autophagy contributes to its chemoresistance in hepatic cancer cells / 药学学报

Autophagy, an evolutionarily conserved process by which components of the cell are degraded in lysosomes, may facilitate survival of cancer cells under stress conditions. 8-Azaguanine (8-AG), an inhibitor of purine nucleotide biosynthesis, shows antineoplastic activity in multiple tumor cells. However, chemoresistance has restricted its development as an anticancer agent, and the mechanism of 8-AG resistance is not fully understood. We report here that 8-AG induces a protective autophagy to eliminate its cytotoxicity, and inhibition of autophagy increases cellular sensitivity of cancer cells to 8-AG treatment. Using HepG2 or SMMC-7721 hepatic cancer cell lines, we found that 8-AG inhibited cell viability and induced intrinsic apoptosis, accompanied by the up-regulation of the pro-apoptotic protein BimS, one of Bim (also known as BCL-2-like protein 11, BCL2L11) isoforms. Furthermore, 8-AG treatment enhanced the autophagy flux by promoting the dephosphorylation and activation of Unc-51-like autophagy activating kinase 1 (ULK1) via Akt/mTORC1 (mammalian target of rapamycin complex 1) signaling inhibition. Depletion of autophagy-related gene 7 (ATG7) markedly enhanced the level of BimS, and promoted cell death in response to 8-AG. 8-AG in combination with autophagy inhibitor chloroquine (CQ) or bafilomycin A1 (Baf A1) promoted the 8-AG-induced apoptosis in hepatic cancer cells. Altogether, these findings suggest that autophagy promotes chemoresistance of cancer cells for 8-AG, and blocking autophagy increases cellular sensitivity of cancer cells to 8-AG treatment.

Adult-onset atopic dermatitis: a new concept worthy of attention / 中华皮肤科杂志

Traditionally, it is believed that atopic dermatitis (AD) usually starts in infancy or childhood. However, adult-onset AD (adult-onset AD) occurring at the age of ≥ 18 years is not uncommon, but has not received due attention. There are overlaps and differences between adult-onset AD and childhood-onset AD in terms of genetic factors, triggers, pathogenesis, clinical manifestations, etc. It is undoubtedly of great practical significance to understand and accept the concept of adult-onset AD in clinical practice. However, there are many problems to be solved, especially the establishment of special diagnostic criteria and management models of adult-onset AD.

Reliability of the measurement of glenoid bone defect in anterior shoulder instability / 中华医学杂志(英文版)

Background@#The size of the glenoid bone defect is an important index in selecting the appropriate treatment for anterior shoulder instability. However, the reliability of glenoid bone defect measurement is controversial. The purpose of the present study was to investigate the reliabilities of measurements of the glenoid bone defect on computed tomography and to explore the predisposing factors leading to inconsistency of these measurements.@*Methods@#The study population comprised 69 consecutive patients who underwent surgery for recurrent anterior shoulder dislocation in Peking University Fourth School of Clinical Medicine from March 2016 to January 2017. The glenoid bone defect was measured by three surgeons on 'self-confirmed’ and 'designated’ 3-D en-face views, and repeated after an interval of 3 months. Measurements included the ratio of the defect area to the best-fit circle area, and the ratio of the defect width to the diameter of the best-fit circle. The inter- and intra-observer reliabilities of the measurements were evaluated using intraclass correlation coefficients (ICCs). The maximum absolute inter- and intra-observer differences and the cumulative percentages of cases with inter- and intraobserver differences greater than these respective levels were calculated.@*Results@#Almost all linear defect values were bigger than the areal defect values. The inter-observer ICCs for the areal defect were 0.557 and 0.513 in the 'self-confirmed’ group and 0.549 and 0.431 in the 'designated’ group. The inter-observer reliabilities for the linear defect were moderate or fair in the 'self-confirmed’ group (ICC = 0.446, 0.374) and 'designated’ group (ICC = 0.402, 0.327). The ICCs for intra-observer measurements were higher than those for inter-observer measurements. The respective maximum interand intra-observer absolute differences were 13.9% and 13.2% in the 'self-confirmed’ group, and 15.8% and 9.8% in the 'designated’ group.@*Conclusions@#The areal measurement of the glenoid bone defect is more reliable than the linear measurement. The reliability of the glenoid defect areal measurement is moderate or worse, suggesting that a more accurate and objective measurement method is needed in both en-face view and best-fit circle determination. Subjective factors affecting the glenoid bone loss measurement should be minimized.

A total of 144 patients with CIU from 3 research centers were enrolled into this study, and randomly and equally divided into a test group and a control group. The test group administrated olopatadine hydrochloride 5 mg twice a day for 28 consecutive days, while the control group administrated levocetirizine hydrochloride 5 mg in the forenoon and a placebo tablet of olopatadine hydrochloride 5 mg in the afternoon for 28 consecutive days. The symptom score reducing index(SSRI)served as the primary outcome, and global assessment score for efficacy and total response rates as the secondary outcome. Results Totally, 137 patients completed the trial, including 70 in the test group and 67 in the control group. As intention-to-treat analysis showed, there were no significant differences in the total response rate between the test group and control group on day 7 (64.29% (45/70)vs. 56.72%(38/67), P > 0.05), 14(82.86%(58/70)vs. 74.63%(50/67), P > 0.05), or 28(87.14%(61/70)vs. 77.61%(52/67), P >0.05)after start of treatment. The SSRI was significantly higher in the test group than in the control group after 4 weeks of treatment(82.67% ± 22.70% vs. 70.51% ± 32.07%, P 0.05), and adverse reactions mainly included lethargy, dry mouth, fatigue, etc. Conclusion Olopatadine hydrochloride is effective and safe for the treatment of CIU.

Primary cutaneous diffuse large B-cell lymphoma, leg type: a study of clinicopathology, immunophenotype and gene rearrangement / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the clinicopathologic features, immunophenotype and gene rearrangement of primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL).</p><p><b>METHODS</b>Seven cases of PCLBCL were enrolled into the study. Clinicopathologic analysis, immunohistochemical staining and gene rearrangement for IgH and Igκ were undertaken in the study.</p><p><b>RESULTS</b>All the seven cases were male, and the median age was 72 years. Patients usually presented with multiple purple tumors, nodules, papules and infiltrative plaques. Two patients had a history of leg injury before onset, and one had mosquito bites. Histologically, the tumor involved the dermis and subcutis with dense and diffuse infiltrative pattern composing of centroblasts and/or immunoblasts. Immunohistochemical staining showed that seven cases (7/7) expressed CD20, six (6/6) expressed bcl-2, four (4/4) expressed MUM-1, four (4/5) expressed CD79a, four (4/5) expressed PAX-5 and four (4/6) expressed bcl-6, respectively. All cases did not express CD3ε, CD45RO, CD10 and CD30. IgH gene rearranged bands were detected in three (3/6) cases and Igκ was detected in one (1/5) case. Six of the seven cases died and the remaining patient, who was 44-year-old, was alive after 22 months of follow-up.</p><p><b>CONCLUSIONS</b>PCLBCL is rare, predominantly affects elderly male patients. PCLBCL has poor prognosis and high mortality, but younger patients seem to have better prognosis. Some cases had a history of trauma or mosquito bites. The relationship between the history and the onset of PCLBCL needs further evaluation.</p>

Study on names of Wenyujin Rhizoma Curcumae and Rhizoma Curcumae Longae Concisa and their origins / 中国中药杂志

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.
