The modern statistical and data mining technology is used to analyze the law of the acupoint selection in the treatment of insomnia with acupuncture and moxibustion. The clinical literature on the treatment of insomnia with acupuncture and moxibustion in recent 10 years is collected from China National Knowledge Infrastructure (CNKI). Excel software is applied to establish the database of acupuncture prescriptions for insomnia so as to conduct the descriptive analysis, association rule analysis and clustering analysis on the data. In the treatment of insomnia with acupuncture and moxibustion, Shenmen (HT 7) is of the highest frequency and most acupoints were selected from the Governor Vessel. The commonly used acupoints are located on the head, face, neck and nape region. The combination of the local acupoints with the distal ones is predominated. The crossing points among the specific points present the advantage in the treatment. The association: rule analysis indicates the highest, correlation among Taixi (KI 3), Sishencong (EX-HN 1) and Shenmen (HT 7). The clustering analysis results in 6 effective clusters and 10 pairs of key points and summarizes the common law of the acupoint combination for insomnia. All of these provide the reference to the treatment of insomnia with acupuncture and moxibustion.

This study was aimed to analyze acupoint selection principle for acute gouty arthritis treatment. Literatures on acupuncture treatment of acute gouty arthritis were collected from CNKI in recent 20 years. Excel software was used in the establishment of database on main acupoints for acute gouty arthritis treatment. On Windows 8 platform, SPSS 17.0 and Clementine 12.0 software were used in the descriptive analysis, association rules analysis and cluster analysis. The results showed that the top three acupionts with the highest frequency of application were Sanyinjiao (SP 6), Zusanli (ST 36), and Y inlingquan (SP 9). The meridian used with the highest frequency was the spleen meridian of foot Taiyin. The result of association rules analysis showed that Sanyinjiao (SP 6)-Xuehai (SP 10)-Quchi (LI 11) was the most relational one. The cluster analysis indicated the top four core cluster groups including Xiangu (ST 43)-Neiting (ST 44)-Xingjian (LR 2), Xuehai (SP 10)-Hegu (LI 4)-Quchi (LI 11), Taibai (SP 3)-Y inbai (SP 1)-Dadu (SP 2)-Fenglong (ST 40), and Zhubin (KI 9)-Zhigou (TE 6)-Gongsun (SP 4)-Bafeng (EX-LE 10). It was con-cluded that the clinical acupoint selection and combination principle in acute gouty arthritis treatment were analyzed through large amount of data. It can provide evidences and references for acupuncture clinical practice.

Objective To explore the potential key risk factors of schistosomiasis transmission in potential endemic areas so as to provide the evidence for setting up the prediction and surveillance systems of schistosomiasis outbreak epidemic. Methods From 2008 to 2012,fixed and mobile surveillance sites in potential endemic areas of 2 counties in Hubei Province were selected. The immunological assays and stool examinations were carried out to investigate the schistosome infection situation of local people, mobile population and livestock. The distribution of Oncomelania hupensis snails was investigated in risk areas and suspicious ar-eas,and spreading patterns of snails were observed in the rivers that directly connected with the Yangtze River. Results A total of 6 052 local people aged 6-65 years were screened by IHA immunological tests,and the positive rate of antibody was 1.19%(72/6 052). Totally 72 antibody positives were examined by Kato-Katz technique and there were no positives. A total of 5 004 mo-bile persons were tested by IHA immunological tests and the positive rate was 1.36%(68/5 004). Totally 68 antibody positives were examined by Kato-Katz technique and there were no positives. Totally 287.07 hm2 potential endemic areas were investigated for Oncomelania snail detection,and no snails were found. The investigation on snail spreading patterns and the surveillance on suspicious circumstances were carried out,with no snails found. Conclusions In the schistosomiasis potential endemic areas, some positives of IHA immunological tests are found. Therefore,monitoring is still needed to be strengthened.

Objective:To observe the short-term effects of intravitreal injection of aflibercept (IVA) for initial treatment and dressing change on exudative age-related macular degeneration (eAMD).Methods:A retrospective clinical study. From June 2018 to February 2021, forty-nine eAMD eyes of 38 patients who underwent IVA treatment in Department of Ophthalmology of Central Theater Command Hospital of People’s Liberation Army were included in the study. Among them, there were 24 males with 29 eyes and 14 females with 20 eyes; the average age was 66.82±8.71 years. All affected eyes were treated with IVA. The initial loading dose was 2.0 mg, which was injected once a month for 3 consecutive months, followed by monthly review and treatment as needed. Of the 49 eyes, 26 eyes were initially treated (initial treatment group), they were diagnosed within 3 months of the first onset and followed by IVA treatment, and no intraocular drugs and surgery were performed from the onset to the first diagnosis. Twenty-three eyes were treated with drug exchange therapy (dressing change group), they received intravitreal injection of ranibizumab and/or conbercept more than 4 times 6 months before the replacement therapy, during which there was persistent interlaminar cystoid edema and/or subretinal fluid (SRF) in the macular area and no improvement in pigment epithelial detachment (PED). Before IVA treatment, there were no statistically significant differences in the best corrected visual acuity (BCVA), foveal thickness (CMT), PED height (PEDH), and PED volume (PEDV) of the two groups of eyes before IVA treatment ( P>0.05). The same equipment and methods as before treatment were used for related examinations, and the changes of BCVA, CMT, PEDH, PEDV and complications of the two groups of eyes were recorded in 1, 3, and 6 months after treatment. The comparison of BCVA, CMT, PEDH, and PEDV between the two groups were used repeated measures analysis of variance. Results:Six months after treatment, the number of IVA injections in the eyes of the initial treatment group and dressing change group were 4.15±0.73 and 4.39±0.72 times, respectively, and the difference was not statistically significant ( t=-1.141, P=0.260). The BCVA, CMT, PEDH, and PEDV of the the initial treatment group ( F=5.345, 22.995, 6.764, 5.425) and the dressing change group ( F=12.519, 15.576, 8.843, 9.406) were significantly improved compared before treatment with 1, 3, and 6 months. All were statistically significant ( P<0.05). There was no significant difference in BCVA, CMT, PEDH, and PEDV between the initial treatment group and the dressing group at each time point after treatment ( F=1.741, 0.069, 0.876, 3.455; P>0.05). During the follow-up period, none of the affected eyes had complications such as persistent intraocular pressure increase, endophthalmitis, and retinal pigment epithelial tear. Conclusions:IVA can improve eyesight of patients with eAMD and reduce CMT, PEDH, and PEDV. The initial treatment and dressing change have the same effect.

Objective:To investigate the regulatory effect of long non-coding RNA (lncRNA) FTX on gastric cancer cell proliferation through miR-22-3p/NOD-like receptor protein 3 (NLRP3) inflammasome pathway.Methods:The gastric cancer cell line NCI-N87 were divided into blank control group, si-FTX-NC group, si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group. Quantitative real-time fluorescent PCR was performed to analyze the expression levels of lncRNA FTX and miR-22-3p, clone formation assay was performed to analyze the proliferation ability of NCI-N87 cells, western blotting was performed to analyze the expressions of NLRP3 inflammasome pathway proteins, and dual-luciferase reporter assay was performed to analyze the targeting relationship between lncRNA FTX and miR-22-3p.Results:The relative expressions of lncRNA FTX in the blank control group, si-FTX-NC group, si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group were 1.03±0.09, 1.01±0.15, 0.42±0.08, 0.45±0.06 and 0.46±0.13 respectively, with a statistically significant difference ( F=52.19, P<0.001). The relative expressions of miR-22-3p were 1.04±0.12, 0.97±0.08, 2.26±0.15, 2.23±0.13 and 1.15±0.11 respectively, with a statistically significant difference ( F=178.53, P<0.001). Compared with the blank control group and si-FTX-NC group, the relative expressions of lncRNA FTX in the si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group decreased (all P<0.001). Compared with the blank control group, si-FTX-NC group and si-FTX+miR-22-3p inhibitor group, the relative expressions of miR-22-3p in the si-FTX group and si-FTX+miR-22-3p inhibitor-NC group increased (all P<0.001). The clones of the five groups were 115.50±7.25, 112.33±8.46, 54.83±5.17, 56.17±6.32 and 85.67±9.43, with a statistically significant difference ( F=91.67, P<0.001). The levels of NLRP3 protein in the five groups were 1.84±0.17, 1.86±0.12, 0.95±0.09, 0.97±0.11 and 1.28±0.19, with a statistically significant difference ( F=60.62, P<0.001). Compared with the blank control group and si-FTX-NC group, the number of clones and the level of NLRP3 protein of the si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group decreased (all P<0.05). Compared with the si-FTX+miR-22-3p inhibitor group, the number of clones and the level of NLRP3 protein in the si-FTX group and si-FTX+miR-22-3p inhibitor-NC group decreased (all P<0.05). The dual-luciferase reporter assay found that miR-22-3p was the target gene of lncRNA FTX. Conclusion:Silencing the expression of lncRNA FTX can inhibit the proliferation of gastric cancer cells, and the mechanism may be related to the regulation of lncRNA FTX on the miR-22-3p/NLRP3 inflammasome pathway.

Objective:To observe the efficacy of intravitreal injection of aflibercept (IVA) in the treatment of exudative age-related macular degeneration (wAMD) combined with RPE detachment (PED).Methods:A retrospective case study. From June 2018 to June 2019, 32 eyes (overall group) of 27 wAMD patients with PED were included in the study. All eyes were treated with IVA. The initial loading dose was 2.0 mg, which was injected once a month for 2 consecutive months and and then use a PRN regimen after evaluation. According to the maximum height of PED (PEDH) 2 months after treatment, the overall group was divided into the response group and the partial response group, with 20 (62.50%) and 12 (37.50%) eyes respectively. The response group: PEDH decreased by ≥25% compared with before treatment. The partial response: PEDH decreased by <25%. The macular fovea was scanned with the 3D-OCT 2000 instrument from Topcon (Japan). PEDH, PED area (PEDA), PED volume (PEDV), and macular foveal retinal thickness (CMT) were measured. There was no significant difference in BCVA, CMT, PEDH, PEDA, and PEDV of the eyes in the response group and the partial response group ( t=-0.791, -0.488, -0.900, -1.130, -0.400; P=0.435, 0.630, 0.380, 0.270, 0.690). The changes of BCVA, PEDH, PEDA, PEDV, CMT in each group were observed before treatment and 1, 2, 4, and 6 months after treatment. The comparison of BCVA and PED-related indicators and CMT before and after treatment were performed by repeated measures analysis of variance. Results:Compared with before treatment, the BCVA, CMT, PEDH, PEDA and PEDV of the eyes in the overall group, the response group, and the partial response group were obviously improved after treatment. Among them, there were statistically significant differences in all indicators of the overall group and the response group ( FBCVA=5.871, 3.798; P=0.001, 0.019. FCMT=24.526, 14.109; P=0.000, 0.001. FPEDH=12.569, 12.091; P=0.000, 0.000. FPEDA=7.534, 6.286; P=0.000, 0.000. FPEDV=5.139, 4.104; P=0.004, 0.014); there was no statistically significant difference in PED-related indicators in the partial response group ( FPEDH=3.210, P=0.054; FPEDA=1.913, P=0.183; FPEDV=3.500, P=0.051), the difference between BCVA and CMT was statistically significant ( FBCVA=3.033, P=0.027; FCMT=11.140, P=0.001). Two months after treatment, the eye number of PEDH reduction rate <25%, 25%-<50%, 50%-<75%, and ≥75% were 12 (37.50%), 8 (25.00%), 9 (28.13%), and 3 (9.38%) in the overall group, respectively. And PED in one eye (3.13%) was completely eliminated. Six months after treatment, the proportion was 13 (40.23%), 5 (15.63%), 7 (21.88%) and 7 (21.88%), respectively, among which 4 eyes (12.50%) with PED were completely resolved. Conclusions:Aflibercept treatment of wAMD combined with PED can restore its anatomical indicators and improve visual function of patients in a short time; the efficacy of PED in the PRN stage is related to the efficacy of the loading dose stage.

With "moxibustion" and "warm stimulation" as the keywords, the literature on moxibustion mechanism of warming and dredging from June 1st, 1995 to June 1st, 2016 was collected from PubMed, China National Knowledge Infrastructure (CNKI) and Wanfang database. The startup mechanism of moxibustion warming and dredging function was analyzed in terms of moxibustion warming stimulation. The results were found that moxibustion was based on local rising temperature of acupoint. It activated local specific receptors, heat sensitive immune cells, heat shock proteins and so on to start the warming and dredging function and produce various local effects. The warming stimulation signals as well as subsequent effects through nerve and body fluid pathways induced the effects of further specific target organs and body systems.

Objective: To investigate the influence of tumor necrosis factor-related apoptosis-inducing ligant (TRAIL) deficiency on mice colitis and the gut microbiota composition by inclding the expermental colitis model in tumor necrosis factor-related apoptosis-inducing ligand gene knockout (TRAIL^-/-) mice. Methods: C57BL/6 TRAIL^-/- mice and wild type (WT) mice were selected and assigned into TRAIL^-/- control group (eight mice), TRAIL^-/- colitis group (16 mice), WT control group (eight mice) and WT colitis group (16 mice). The mice of two colitis groups were oral administrated with 3.5% dextran sulphate sodium (DSS) in drinking water for seven consecutive days to induce experimental colitis model. The severity of colitis was evaluated by clinical appearance and histopathological examination. The colonic tissue samples of mice were collected and microbiota profile was analyzed by 16S rDNA sequencing method. USEARCH software and R language were used to analyze the difference of gut microbiota among TRAIL^-/- control group, TRAIL^-/- colitis group, WT control group and WT colitis group. T test and Mann-Whitney U test were used for statistical analysis. Results: After modeling, the disease activity index (DAI) of WT colitis mice and TRAIL^-/- colitis mice both gradually increased over time. Furthermore, compared with colitis mice, TRAIL^-/- colitis mice developed body weight loss, diarrhea and hemafecia earlier. On the seventh day after modeling, the percentage of body weight loss of TRAIL^-/- colitis mice and WT colitis mice was (28.98±2.84)% and (17.87±3.70)%, respectively; and the difference was statistically significant (t=9.53, P<0.01). The length of colon of TRAIL^-/- colitis mice was shorter than that of WT colitis mice ((4.63±0.28) cm vs. (6.02±0.41) cm), and the difference was statistically significant (t=11.20, P<0.01). The DAI of TRAIL^-/- colitis mice was higher than that of WT colitis mice (3.00±0.00 vs. 2.32±0.05), and the difference was statistically significant (t=54.40, P<0.01). The histological score of TRAIL^-/- colitis mice was higher than that of WT colitis mice (6.19±0.25 vs. 3.87±0.22), and the difference was statistically significant (t=27.87, P<0.01). Under the microscope, colonic mucosal epithelial injury, crypt structure destruction and inflammatory cell infiltration were more obvious in TRAIL^-/- colitis mice than in WT colitis mice. The alpha diversity of colonic flora was more significant in TRAIL^-/- colitis group compared with that of WT colitis group. At the family level, the relative richness of Deferribacteraceae, Ruminococcaceae, Rikenellaceae, F16 and Paraprevotellaceae significantly increased in TRAIL^-/- colitis group, but the relative richness of Enterococcaceae obviously reduced ((19.839±19.991)% vs. (7.224±11.241)%, (3.564±2.543)% vs.(2.861±3.821)%, (0.123±0.066)% vs. (0.068±0.049)%, (0.032±0.033)% vs. (0.006±0.011)%, (0.153±0.098)% vs. (0.062±0.054)% and (0.013±0.027)% vs. (0.054±0.121)%, respectively; U=51, 69, 53, 35, 49 and 69, respectively; P<0.01 and 0.05, respectively). In addition, at the genus level the relative richness of Oscillospira, Mucispirillum and Cytophaga in TRAIL^-/- colitis group remarkably elevated, and the relative richness of Enterococcus significantly decreased ((2.363±2.147)% vs. (1.813±2.847)%, (19.839±19.991)% vs. (7.223±11.241)%, (0.104±0.153)% vs. (0.046±0.069)% and (0.076±0.049)% vs. (0.135±0.074)%, respectively; U=70, 51, 66 and 65, respectively; P <0.05 and 0.01, respectively). Conclusion TRAIL deficiency aggravate DSS-induced colitis, and increase the alpha diversity of colonic microbiota in colitis mice.
