ABSTRACT
AIM: To investigate the effect of the expression of miR-375 on the proliferation and invasion of choroidal melanoma(CM)MUM-2B cells.METHODS: MUM-2B cells were cultured and were transfected with miR-375 mimic sequence(mimic group), miR-375 inhibitor sequence(inhibitor group), negative control group and no treatment(blank group). The qRT-PCR, CCK-8, apoptosis and Transwell experiments were used respectively to detect the expression of miR-375, cell proliferation activity, apoptosis, cell migration and invasion.RESULTS: Compared with the negative control group(1.01±0.10)and the blank group(1.03±0.07), the expression level of miR-375 in the cells of the mimic group(2.65±0.15)was increased, while the expression level of miR-375 in the cells of the inhibitor group(0.28±0.06)was decreased(P<0.05). Compared with the blank group and negative control group, the OD values of the cells in the mimic group at 24, 48, 72, and 96h were decreased(P<0.05), while the OD values of the cells in the inhibitor group at 24, 48, 72, and 96h were increased(P<0.05). Compared with the apoptosis rates in the blank group and negative control group, which were(20.54±4.01)% and(22.80±4.28)%, the apoptosis rate in the mimic group(39.11±3.37)% was increased(P<0.05), while it was decreased in the inhibitor group(10.13±2.17)%(P<0.05). Compared with the blank group and negative control group, the number of migration cell and the number of invasion cell in the mimic group were decreased(P<0.05), while the number of migration cell and the number of invasion cell in the inhibitor group were increased(P<0.05). CONCLUSIONS: Up-regulating the expression of miR-375 in MUM-2B cells can reduce cell proliferation activity, accelerate cell apoptosis, and inhibit cell migration and invasion, while down-regulating the expression of miR-375 has the opposite effect. It indicates that miR-375 may play the function of tumor suppressor in the course of CM.
ABSTRACT
@#AIM: To observe the efficacy of pterygium excision combined with autologous limbal epithelial bulbar conjunctival transplantation in the treatment of patients with pterygium. METHODS:Prospective controlled study. A total of 102 patients(102 eyes)with pterygium treated in the hospital between October 2015 and October 2019 were selected as study subjects, and they were divided into observation group and control group according to the random number table method, with 51 cases in each group. The control group was treated with pterygium excision combined with amniotic membrane transplantation, and the observation group was given pterygium excision combined with autologous limbal epithelial bulbar conjunctival transplantation. The perioperative indicators(intraoperative blood loss, surgical time, corneal epithelial repair time)and clinical efficacy at 3mo after surgery were compared between the two groups, and the disease recovery-related indicators \〖tear film break-up time(BUT), uncorrected visual acuity(UCVA), Schirmer Ⅰ test(SⅠt), corneal astigmatism degree(CAD)\〗 before and 3mo after surgery, postoperative aesthetic degree and recurrence during follow-up were recorded.RESULTS:The corneal epithelial repair time in observation group was shorter than that in control group(4.14±1.35 <i>vs</i> 4.72±1.37d,<i>P</i><0.05), while the surgical time was longer than that in control group(32.24±6.69 <i>vs</i> 29.67±5.21min,<i>P</i><0.05), and there was no statistical significance in the intraoperative blood loss between the two groups(<i>P</i>>0.05). At 3mo after surgery, there was no statistical difference in the effective rate of treatment between the two groups(86.3% <i>vs</i> 78.4%, <i>P</i>>0.05). At 3mo after surgery, the BUT, UCVA and SⅠt in the two groups were significantly enhanced compared with those before surgery(all <i>P</i><0.05), and the UCVA and SⅠt in observation group were higher than those in control group(all <i>P</i><0.05), but there was no statistical difference in the BUT between the two groups(<i>P</i>>0.05). The CAD in the two groups was significantly lower than that before surgery(<i>P</i><0.05), but the difference was not significant between the groups(<i>P</i>>0.05). At 3mo after surgery, the scores of dimensions of aesthetic scale for pterygium treatment(ocular recovery, subjective symptoms)were significantly higher in observation group than those in control group(all <i>P</i><0.05), but there were no statistical differences in the scores of cleanliness of surgical area and congestion between the two groups(all <i>P</i>>0.05). There was no statistically significant difference in recurrence rate between the two groups during follow-up(<i>P</i>>0.05).CONCLUSION: Pterygium excision combined with autologous limbal epithelial bulbar conjunctival transplantation can effectively treat pterygium and prevent recurrence, and it has faster postoperative recovery and better aesthetic degree compared to pterygium excision combined with amniotic membrane transplantation.
ABSTRACT
Chrysosplenium nudicaule,Tibetan name " Yajima",is recorded as an effective medicine for the treatment of liver and gallbladder diseases by Tibetan Pharmacopoeia published in the past dynasties,but its traditional efficacy has not yet been investigated by means of modern pharmacological research methods. In this paper,the protective effect of extract of C. nudicaule(ECN) on liver injury in mice was observed by using the mice model of intrahepatic cholestasis(IC) induced by α-naphthyl isothiocyanate(ANIT) and the possible mechanism by which ECN work as the therapeutic agent was discussed. The results showed that the serum levels of AST,ALT,ALP,DBIL,TBIL and TBA of the model mice were notably reduced in dose-dependent manner(P<0. 01,P<0. 05). The activity of SOD and GSH-Px in the liver homogenate of mice was increased,while the content of MDA was decreased(P<0. 01,P<0. 05).Pathological examination of liver in mice showed that ECN could improve the pathological changes of liver tissue in mice. The mRNA expression level of genes related to bile acid metabolism were detected by RT-PCR and the results suggested that ECN could significantly increase the expression of genes such as BSEP,FXR and MRP2(P<0. 01,P<0. 05),meanwhile significantly reduce the expression of CYP7 A1(P<0. 01,P<0. 05). These results confirmed the protective effect of ECN on intrahepatic cholestasis-induced liver injury in mice,and indicated that the mechanism may be related to activating FXR and its target genes,reducing bile acid synthesis and increasing bile acid excretion. This study provides a modern pharmacological basis for the clinical application of Yajima in Tibetan medicine.

OBJECTIVE: To evaluate therapeutic efficacy and safety of allopurinol versus (vs.) TCM prescription for gout in the treatment of gout, and to provide evidence-based reference for clinical treatment of gout. METHODS: Retrieved from PubMed, Embase, Medline, The Cochrane library, Chinese Journal Full-text Database (CJFD), China Scientific Journal Database (CSJD) and Wanfang database, randomized controlled trials (RCTs) about therapeutic efficacy (total response rate, level of uric acid) and safety (the occurrence of ADR) of TCM prescription for gout alone or combined with allopuinol (trial group) vs. allopurinol (control group) in the treatment of gout were collected. After data extraction of clinical studies meeting inclusion criteria, Cochrane system evaluator manual 5. 1. 0 was used to evaluate the quality of included studies, and Meta-analysis was conducted by using Rev Man 5. 3 statistical software. RESULTS: A total of 20 RCTs were included, involving 1 961 patients. Results of Meta-analysis showed that total response rate of trial group was significantly higher than that of control group [OR=2. 29, 95％ CI(1. 84, 2. 84), P<0. 001], uric acid level was significantly lower control group [MD= -27. 99,95％ CI(-33. 04, -22. 93),P<0. 001],with statistical significance. The incidence of ADR in trial group was significantly lower than control group, with statistical significance (P<0. 05). CONCLUSIONS: Therapeutic efficacy and safety of TCM prescription are better than those of allopuinol for gout.
