Objective:To analyze the research status of scleral lenses by bibliometric method based on the relevant collection of scleral lenses in the Web of Science database.Methods:Using the scleral lens-related literature collected in the Web of Science Core Collection database in the past 10 years (January 2013 to December 2022) as the object of analysis, bibliometric method and CiteSpace tools were used to conduct visual analysis of the literature.A comprehensive analysis of the volume of literature published, the distribution of countries and institutions, the information of core authors, the distribution of journals, and keyword clustering was performed.Results:A total of 340 articles were retrieved, which were published in 54 journals, with an average of 6.3 articles per journal, involving 301 authors.Research in this area covered 35 countries or regions, and 256 research institutions were involved.Discipline development was mainly in the United States, India, Spain and Australia.The main focus was on scleral lens (scleral contact lens), ocular surface disease, corneal edema, miniature scleral lens, etc.In the past 10 years, the trend of research hot topics in scleral lenses had shifted from the initial study of combining scleral contact lenses with ocular surface diseases to the subsequent study of prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape.From 2013 to 2021, the main focuses were ocular surface diseases, scleral contact lenses, and corneal edema.After 2021, research on ocular surface diseases and keratoplasty declined.From January 2013 to December 2022, emergent keywords related to scleral lens mainly included scleral contact lens, transplantation, anti-host disease, prosthetic device in the first stage, artificial replacement of ocular surface ecosystem and irregular cornea in the second stage, and the research on corneal gap and characteristic shape in the third stage.Optical coherence tomography and corneal topography were commonly used examinations for scleral lens research and fitting.Conclusions:At present, the scleral lens is mainly used for dry eye, corneal diseases, corneal ectasia, keratitis, and corneal transplantation, especially after penetrating keratoplasty and refractive errors.Prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape are the research hotspots in scleral lenses.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.

Unilateral biportal endoscopic surgery, micro-endoscopic discectomy, micro-endoscopic laminoplasty, and Destandau mobile endoscopic discectomy have been described as four major techniques in the field of endoscopic spine surgeries. Compared with the coaxial endoscopy, the unilateral biportal endoscopic surgery is characterized by separated channels for observation and operation, making operative procedures more flexible, vision field wider, and requirements for surgical instruments less demanding. Although the anatomical basis of its surgical approach is similar to that of micro-endoscopic spine surgery, this technique can significantly reduce the injury to the paravertebral muscle and protect the stability of the surgical segment of the spine, leading to quick and wide applications in the clinical treatment of degenerative lumbar diseases with good clinical efficacy. The present article reviews this surgical technique from the aspects of technological development, anatomical basis, clinical application, complications, and prospects.

OBJECTIVE: To explore the therapeutic mechanism of Liushen Wan (LSW) against colitis-associated colorectal cancer (CAC) by network pharmacology. METHODS: TCMSP, BATMAN-TCM, CNKI, PubMed, Genecards, OMIM, and TTD databases were used to obtain the related targets of LSW and CAC. The common targets of LSW and CAC were obtained using Venny online website. The PPI network was constructed using Cytoscape 3.8.2 to screen the core targets of LSW in the treatment of CAC. GO and KEGG enrichment analysis were conducted using DAVID database. The therapeutic effect of LSW on CAC was evaluated in a C57BL/6J mouse model of AOM/DSS-induced CAC by observing the changes in body weight, disease activity index, colon length, and size and number of the tumor. HE staining and RT-qPCR were used to analyze the effect of LSW on inflammatory mediators. Immunohistochemistry and TUNEL staining were used to evaluate the effect of LSW on the proliferation and apoptosis of AOM/DSS-treated colon tumor cells. Immunohistochemistry and Western blotting were used to detect the effects of LSW on the expression of TLR4 proteins in CAC mice. RESULTS: Network pharmacology analysis identified 69 common targets of LSW and CAC, and 33 hub targets were screened in the PPI network. KEGG pathway enrichment analysis suggested that the effect of LSW on CAC was mediated by the Toll-like receptor signaling pathway. In the mouse model of AOM/DSS-induced CAC, LSW significantly inhibited colitis-associated tumorigenesis, reduced tumor number and tumor load (P < 0.05), obviously improved histopathological changes in the colon, downregulated the mRNA levels of proinflammatory cytokines, and inhibited the proliferation (P < 0.01) and promoted apoptosis of colon tumor cells (P < 0.001). LSW also significantly decreased TLR4 protein expression in the colon tissue (P < 0.05). CONCLUSION LSW can inhibit CAC in mice possibly by regulating the expression of TLR4 to reduce intestinal inflammation, inhibit colon tumor cell proliferation and promote their apoptosis.

ObjectiveThis study aimed to understand the epidemiological characteristics of hand-foot-mouth disease （HFMD） in Minhang District， Shanghai from 2009 to 2020， and provide a scientific basis for the prevention and control of HFMD. MethodsThe case information of HFMD was collected from the National Notifiable Infectious Diseases Reporting System of Chinese Center for Disease Control and Prevention. We used descriptive epidemiological methods to analyze the population characteristics， temporal and spatial distribution of HFMD， the pathogen composition of the case and its changing trend. ResultsFrom 2009 to 2020， a total of 66，198 cases of HFMD were reported in Minhang District， Shanghai， including 377 severe cases （severe case rate 0.57%） and 3 deaths （severs case fatality rate 0.80%）. There were more cases of HFMD in boys than in girls （1.5∶1）. HFMD patients aged under 5 years predominated， accounting for 88.91% of all cases. Majority of the cases （91.42%） were in scattered children （55.80%） and children in kindergartens （35.62%）. The incidence showed a cyclical trend， with low incidence years and high incidence years appearing alternately. The peak period was from April to July， and sometimes there were small peaks during October to December. A total of 12 years time-space scanning analysis revealed 3 clusters. The cluster centers were located in Wujing Town， Huacao Town and Xinzhuang Town， respectively. The proportion of EV71 in common cases was generally decreasing， and reduced to zero in 2019. The proportion of CoxA6 had increased year by year， and reached 75.00% in 2020. CoxA6 became the dominant pathogen in recent years. The number of severe cases had decreased year by year since 2010， and the dominant pathogen was EV71 （90.03% on average） in severe cases. ConclusionThe incidence of HFMD in Minhang District of Shanghai has a downward trend from 2014. The dominant pathogen changes from EV71 to CoxA6， and the dominant pathogen in severe cases is EV71. The discovered temporal and spatial clustering pattern is helpful for in-depth understanding of the distribution and epidemic trend of HFMD in Minhang District， and provides a scientific basis for epidemic prevention and control.

【Objective】 To investigate the clinical characteristics of COVID-19 induced deaths and analyze the causes of death. 【Methods】 This was a hospital-based, retrospective, observational cohort study involving hospitalized patients diagnosed with COVID-19 in People’s Hospital of Wuhan University during January 27 and February 25, 2020. The clinical data of identified patients who had died of COVID-19 were retrieved and reviewed. We analyzed the death causes and compared the changes in laboratory findings between patients before death and early onset to summarize the inherent clinical characteristics. 【Results】 We recorded a total of 21 deaths, 61.9% of which had occurred due to simple respiratory failure, followed by respiratory failure with myocardial injury (19%), respiratory failure with renal failure (9.5%), and respiratory failure with shock (9.5%). At the late time, lab test data indicated that white blood cells, D-dimer, amino-terminal brain natriuretic peptide precursors, and hypersensitive C-reactive protein significantly increased while counts of lymphosyte significantly decreased (P<0.05). 【Conclusion】 Continuous monitoring of cardiac function, renal function, and infection severity can assess the disease progression accurately. Moreover, timely intervention has a positive effect in reducing COVID-19 mortality.

ObjectiveTo investigate the mechanism of action of Sini powder in the treatment of liver cancer based on network pharmacology and molecular docking. MethodsTraditional Chinese Medicine Systems Pharmacology Database and Analysis Platform was used to obtain the compound and target of Sini powder, and the corresponding gene Symbol was obtained through Uniprot. The disease genes of liver cancer were obtained from Human Genome Database, and the genes with intersection with the target genes of Sini powder were screened out. Cytoscape3.7.1 software was used to draw the map of “traditional Chinese medicine (TCM)-compound-target” network. STRING was used to construct a protein-protein interaction (PPI) network, R studio software was used to conduct gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses on therapeutic targets, and then the results were visualized. The active component with the highest number of targets was selected as the ligand, and the target with the highest degree in the PPI network was selected as the receptor, so as to predict the structure of receptor-ligand complex and the amino acid residues that bind to each other. ResultsIn this study, 91 core targets and 141 relevant active components of Sini powder were screened out, among which quercetin and kaempferol were the main active components in the treatment of liver cancer. TP53 and HSP90AA1 were the main therapeutic targets. The GO enrichment analysis obtained 1007 items which met the screening criteria, which were mainly involved in the biological processes of antioxidation reaction, activity regulation of protein serine and threonine kinase, and cellular stress response. The KEGG enrichment analysis obtained 102 pathways, which mainly regulated the hepatitis B pathway and the PI3K-Akt signaling pathway in the prevention and treatment of liver cancer. The results of molecular docking showed a synergistic antitumor effect between the crystal structure domains VAL147, CYS220, GLU221, and PRO222 of quercetin-TP53. ConclusionThis study reveals the mechanism of action of Sini powder in the treatment of liver cancer by acting on multiple targets and signaling pathways, which provides a theoretical basis for biological experiments.

OBJECTIVETo compare the effects between acupuncture with regulating mind and spleen and wes-tern medication for diarrhea irritable bowel syndrome (IBS-D).

METHODSEighty-one patients were randomly at the ratio of 2 to 1 assigned into an acupuncture group (54 cases) and a western medication group (27 cases). Acupuncture with regulating mind and spleen was applied in the acupuncture group for 6 weeks at Baihui (GV 20), Yintang (GV 29), Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Sanyinjiao (SP 6), and Taichong (LR 3), once every other day, 3 times a week. Pinaverium bromide tablet was used orally in the western medication group for 6 weeks, 50 mg a time, 3 times a day. IBS symptom severity score (IBS-SSS) were observed before and after 1-week, 6-week treatment. Pittsburgh sleep quality index (PSQI) was applied before and after 6-week treatment. Also, clinical efficacy was evaluated in the two groups.

RESULTSThree patients dropped out in the acupuncture group, and 1 in the western medication group. Except abdominal distension score after 1-week treatment in the western medication group, single scores and total scores of IBS-SSS apparently reduced in the two groups after 1-week and 6-week treatment (<0.01,<0.05). After 1-week treatment, the abdominal pain score of the acupuncture group was obviously lower than that of the western medication group (<0.05). After 6-week treatment, with abdominal pain relief advantage, other results including the number of pain days, defecation satisfaction,life disturbance degree and total score of the acupuncture group were obviously lower than those of the wes-tern medication group (<0.01,<0.05). After 6-week treatment, the PSQI score and its change before and after treatment in the acupuncture group were superior to those in the western medication group (both<0.05). The relief rate and relief plus obvious effective rate in the acupuncture group were higher than those in the western medication group[51.0% (26/51) vs 19.2% (5/26),<0.01; 64.7% (33/51) vs 34.6% (9/26),<0.05].

CONCLUSIONSAcupuncture with regulating mind and spleen for diarrhea irritable bowel syndrome can more effectively relieve abdominal pain than pinaverium bromide tablet at the early stage. Its total effect and single effects are better at the later stage on abdominal pain, seizure frequency, defecation satisfaction, life disturbance, and sleep quality.

Objective To study the incidence and risk factors ofdefecatory dysfunction in acute minorischemic strokepatientsandexplore the influence of the risk factors onprognosis.Methods Clinical data of 274 patients with acute minor ischemic strokewere reviewed and analyzed retrospectively.According to the presence of poststroke defecatorydysfunction,they were divided into defecatory dysfunction group and non-defecatory dysfunction group.The factors associated withdefecatory dysfunctionwere analyzed by univariate analysis and multivariatelogisticanalysis respectively,followed by investigating their effects on the prognosis.Results 74 patients of them with acute minor ischemic stroke had defecatory dysfunction.The univariate analysis indicated that4 factors including baseline NIHSS scorewere the risk factors.Multivariate logistic analysis showed that female,age,diabetes mellitus and baseline NIHSS score were independent risk factors for defecatory dysfunction.The scores of modified Rankin Scale (mRS) after 3 months in minor stroke patients with defecatory dysfunction wassignificantly higher(P ＜ 0.05).Baseline NIHSS score was a predictive factor for the prognosis of post-stroke defecatorydysfunctionpatients.Conclusions Defecatory dysfunction in acute minor stroke patients may increase the risk of poor prognosis.The female,elderlypatients as well those with diabetes mellitus and serious neurologicalfunction deficits are more likely to suffer post-stroke defecatory dysfunction.
