1.Research progress on the functions of BORIS and related drug development
Acta Pharmaceutica Sinica 2024;59(7):1905-1915
Brother of regulator of imprinted sites (BORIS), also known as CCCTC binding factor-like (CTCFL), is a relatively newly discovered cancer-testis antigen. Drug development related to BORIS has been carried out in multiple directions, including small molecules, small RNA molecules, polypeptides, vaccines, and cellular therapies. Due to its unique ability to interfere with the higher-order spatial structure of the genome, BORIS may represent a new class of drug targets. Here we systematically review the molecular biology research results related to BORIS, including the diversity of its gene products, the multipartite interactions mediated by BORIS, the subsequent impact on signaling pathways, and current drug development strategies, in order to gain a better understanding of the molecular mechanisms of BORIS in both upstream and downstream regulation networks and to identify potential research directions for further breakthroughs.

OBJECTIVETo explore the value of the application of oil red O staining in spinal cord injury (SCI) of rats.
METHODSWith simple randomization, 24 Spargue-Dawley male rats were divided into normal control group including 6, and SCI group including 18. Spinal cord was transected at spinal lever T10 to build SCI model. Six rats of SCI group were sacrificed randomly at 1, 2, 4 weeks after surgery. After the spinal cord tissue sections were made, oil red O staining methods were used to observe the changes at the end of transected spinal cord. Images were analyzed by Image-Pro Plus 6.0 and SPSS 20.0 software.
RESULTSThe oil red O staining of normal control group showed that white matter surrounded by myelin sheath was clear and obviously distinctive from grey matter. Uneven and strengthened staining in oil O was observed in grey matter of SCI group at 1, 2, 4 weeks post-SCI.
CONCLUSIONIt is a good method to label the myelin sheath in spinal cord and distinct white matter from grey matter by oil red O staining. Analysis of the images showed that lipid may become another target for drugs, which needs more researches.

AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma.
METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma.
RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them,
the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%).
CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.
METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.
RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).
CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.
