AIM: To analyze the clinical outcomes of cyclosporine combined with lacrimal plug in the treatment of dry eye in patients with primary Sjögren's syndrome.METHODS: The clinical data of 60 patients(120 eyes)who were admitted to the ophthalmology department and rheumatology and immunology department of Baoding No.1 Central Hospital and were diagonosed with siogren's syndrome dry eye after multidisciplinary consultation from June 2022 to September 2023 were retrospectively analyzed. All the patients received regular treatment of primary Sjögren's syndrome, and they were divided into three groups according to treatment methods: A, B and C, with 20 cases(40 eyes)in each group. The group A received 0.3% sodium hyaluronate eyedrops, the group B received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops, and the group C received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops combined with binocular lacrimal plugs. The ocular surface disease index(OSDI)score, conjunctival hyperemia score, tear film breakup time(BUT), tear meniscus height(TMH), corneal fluorescein staining(FL)score and tear secretion of the three groups of patients were compared before and at 4, 8 and 12 wk after treatment. The contents of inflammatory factors such as interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)in tears were detected before and at 12 wk after treatment.RESULTS: At 4, 8 and 12 wk after treatment, the scores of OSDI, conjunctival hyperemia score and FL in the three groups of patients were lower than those before treatment, and the BUT, TMH and tear secretion were higher than those before treatment(all P<0.001). The OSDI score of the group C was lower than that of the group A and B, and the group B was lower than the group A(all P<0.001). The BUT, TMH and tear secretion of the group C were higher than those of the group A and B, with the group B higher than the group A(all P<0.001). At 12 wk after treatment, the levels of IL-6, TNF-α and IL-1β in the tears of the three groups of patients were lower than those before treatment, with the group C lower than the group A and B, and the group B lower than the group A(all P<0.001). There was no statistical significant difference in the incidence of adverse reactions among the three groups of patients(P>0.05).CONCLUSION: The combined use of cyclosporine and lacrimal plug is safe and effective in improving the clinical symptoms of patients with moderate and severe dry eye, promoting the function of tear film and cornea, increasing tears secretion, and reducing the level of tear inflammatory factors.

Objective To establish a method for simultaneous determination of four high-molecular-weight thiol derivatives (TDs) in workplace air by gas chromatography. Methods The four kinds of vapor-phase macromolecular TDs (1-pentanethiol, 1-hexanethiol, 1-benzyl mercaptan, and n-octanethiol) in the workplace air were collected using the GDH-1 air sampling tubes, desorbed with anhydrous ethanol, separated on a DB-FFAP capillary column, and determined by flame ionization detector. Results The quantitation range of the four TDs was 0.30-207.37 mg/L, with the correlation coefficients greater than 0.999 00. The minimum detection mass concentrations and minimum quantitation mass concentrations were 0.18-0.32 and 0.60-1.05 mg/m³, respectively (both calculated based on the 1.5 L sample and 3.0 mL desorption solvent). The mean desorption efficiencies ranged from 87.07% to 103.59%. The within-run and between-run relative standard deviations were 1.92%-8.22% and 1.89%-8.45%, respectively. The samples can be stored at room temperature or 4 ℃ for three days and up to 7 days at -18 ℃. Conclusion This method is suitable for the simultaneous determination of four vapor-phase TDs in workplace air.

AIM: To evaluate the efficacy of 0.05% cyclosporine eye drops in promoting ocular surface recovery following pterygium excision combined with autologous corneal limbal stem cell transplantation.METHODS:This study is a prospective randomized controlled trial, selecting 104 cases(104 eyes)of primary pterygium with monocular onset admitted to Baoding First Central Hospital from September 2023 to September 2024 as the initial sample. The patients were divided into an experimental group and a control group using a random number table method, with 52 eyes in each group. Both groups underwent pterygium excision and autologous corneal limbal stem cell transplantation performed by the same surgeon. The control group received tobramycin dexamethasone eye drops combined with 0.3% sodium hyaluronate eye drops, while the experimental group was additionally treated with 0.05% cyclosporine eye drops. The corneal epithelial repair status, ocular surface function [corneal fluorescein staining(FL)score, Schirmer I test(SIt), break-up time of tear film(BUT)] at preoperative and postoperative time points(1 and 3 mo), and dry eye symptoms [ocular surface disease index(OSDI), standard patient evaluation of eye dryness(SPEED)scores]. Additionally, the recurrence rate and postoperative complications were recorded.RESULTS: During the follow-up period, there was 1 case of loss to follow-up in both the experimental group and the control group, with lost to follow-up rate of 1.9%. Finally, 51 cases in each group completed all followed-up. No statistically significant difference was observed in preoperative general characteristics of patients between the two groups(P>0.05), and there was no statistically significant difference in corneal epithelial repair time or suture removal time(all P>0.05). At 1 mo postoperatively, the SIt and BUT decreased in both groups compared to preoperative levels, with the experimental group showing higher values than the control group(all P<0.05). FL scores increased compared to preoperative levels but were lower in the experimental group(all P<0.05). By 3 mo, the SIt, BUT and FL score of the control group were not statistically different from preoperative levels(all P>0.05), whereas the experimental group showed increased SIt and BUT, which were higher than the control group, and reduced FL scores, and decreased FL scores, which was lower than the control group(all P<0.05). At 3 mo postoperatively, both groups showed increased SIt and BUT compared to 1-month values, with the experimental group outperforming the control group(all P<0.05). FL scores decreased in both groups compared to 1-month values, with the experimental group maintaining lower scores(P<0.05). At 1 mo postoperatively, OSDI and SPEED scores were higher than preoperative levels, with the experimental group higher than the control group(all P<0.05); at 3 mo postoperatively, the scores returned to preoperative level(all P>0.05), and the OSDI and SPEED scores of the control group increased and higher than those of the experiment group(all P<0.05); at 3 mo postoperatively, the OSDI and SPEED scores decreased when compared with 1-month preoperative level, and the experiment group was lower than the control group(all P<0.05). There was no difference in the total incidence of postoperative complications between the two groups(P>0.05). According to the statistics of 6 mo follow-up after operation, there was no recurrence in the experimental group, and the recurrence rate was 11.8% in the control group(P<0.05).CONCLUSION: Adjunctive use of 0.05% cyclosporine eye drops after pterygium excision with limbal stem cell transplantation enhances ocular surface recovery, reduces dry eye symptoms, and lowers recurrence rates without compromising corneal epithelial healing or safety.

Objectives:Present study aimed to use quantitative flow ratio based on Murray's law to analyze the risk factors of impaired side branches perfusion without naked eye visible slowing of blood flow in branches after interventional treatment of true bifurcation lesions of the coronary arteries. Methods:A total of 211 patients with non-left main coronary artery true bifurcation coronary artery disease who underwent percutaneous coronary intervention(PCI)in Hunan Provincial People's Hospital from June 2022 to September 2023 were continuously enrolled,with a total of 234 bifurcation lesions.The general clinical indicators,anatomical characteristics of coronary artery bifurcation lesions,branch protection methods,postoperative branch TIMI blood flow and other data were collected,and quantitative flow ratio(μQFR)was measured for postoperative branch blood vessels.Post-PCI μQFR<0.8 was considered as impaired branch perfusion and was included in the postoperative impaired branch perfusion group(n=51,53 branch lesions).Patients with μQFR≥0.8 were included in the postoperative normal branch perfusion group(n=160,181 branch lesions).Multivariate Logistic regression analysis was used to evaluate the effects of various clinical and anatomical factors on branch perfusion after PCI. Results:The post-PCI branch flow grading of all patients was TIMI grade Ⅲ.The postoperative branch μQFR of 53 vessels(22.6％)in the group with impaired postoperative branch perfusion was 0.70±0.10,and 0.93±0.05 in the group with normal postoperative branch perfusion,and the difference between the two groups was statistically significant(P<0.001).Compared with the postoperative group with normal branch perfusion,the postoperative group with impaired branch perfusion was featured with an elevated branch lesion length,branch reference diameter,postoperative branch opening diameter stenosis rate,postoperative branch narrowest lumen diameter stenosis rate,and a lower main branch-to-branch diameter ratio,preoperative branch narrowest lumen diameter stenosis rate,and preoperative main branch μQFR,all of which were statistically significant(all P<0.05).The postoperative branch opening diameter stenosis rate(r=-0.490,P<0.001),postoperative branch narrowest lumen diameter stenosis rate(r=-0.788,P<0.001),preoperative branch narrowest lumen diameter stenosis rate(r=-0.280,P<0.001),branch narrowest lumen diameter(r=-0.469,P<0.001),branch lesion length(r=-0.157,P=0.016)were negatively correlated with postoperative branch μQFR,and branch reference diameter(r=0.173,P=0.008),main branch/side branch diameter ratio(r=0.194,P=0.003),and branch opening diameter(r=0.328,P<0.001)were positively correlated with postoperative branch μQFR,and none of them were significantly correlated with clinical baseline data(all P>0.05).Multifactorial logistic regression analysis showed that following four factors were independent risk factors for impaired branch perfusion:postoperative stenosis of the narrowest branch lumen diameter(OR=1.228,95％CI:1.144-1.318,P<0.001),postoperative stenosis of the branch opening diameter(OR=1.110,95％CI:1.055-1.168,P<0.001),postoperative stenosis of the narrowest lumen diameter of the main branch(OR=1.115,95％CI:1.042-1.192,P=0.001),and length of the branch lesion(OR=1.121,95％CI:1.021-1.231,P=0016). Conclusions:Some of the patients whose branch flow reached TIMI grade Ⅲ after PCI are still faced the risk of hemodynamical impairment and should be functionally evaluated after PCI.The postoperative stenosis rate of the narrowest branch lumen diameter,postoperative stenosis rate of the branch opening diameter,postoperative stenosis rate of the narrowest lumen diameter of the main branch,and branch lesion length are the risk factors of branch perfusion impairment after PCI for coronary bifurcation lesions.

Objectives:to analyze the efficacy of percutaneous coronary intervention(PCI)for complex left main(LM)lesions combined with chronic total occlusion(CTO)of the right coronary artery. Methods:Ninety patients with complex left main lesions hospitalized in Hunan Provincial People's Hospital from January 2019 to December 2022 were consecutively included.According to the coronary angiographic vascular lesions,patients were divided into complex left main lesions combined with right coronary artery CTO(observation group,n=30)and complex left main lesions without right coronary artery CTO(control group,n=60).The baseline clinical data,intraoperative conditions,angiographic results,and postoperative follow-up results of the patients were analyzed and compared between the two groups. Results:Fifty-eight(64.4%)out of the 90 patients were male.There was no statistically significant difference between the two groups in terms of baseline clinical data(all P>0.05),left main lesion condition(P=1.000),left main calcification condition(P=0.249),and preoperative TIMI flow grading(P=1.000).In the comparison between observation group and the control group,intraoperative occurrence of no-reflow(3.3%vs.5.0%,P=1.000),hypotension(10.0%vs.8.3%,P=1.000),pericardial effusion(3.3%vs.0%,P=0.333),the percentage of intravascular ultrasound(IVUS)use(86.7%vs.90.0%,P=0.635),and the use of circulatory assist device(P=0.699),and the proportion of intraoperative coronary spinning(26.7%vs.21.7%,P=0.597)were all similar between the two groups.The median follow-up time was 14.50(11.83,15.85)months,and the differences in the incidence of major adverse cardiovascular events(MACE)such as recurrent angina,acute myocardial infarction,rebleeding,readmission for heart failure,and cardiac death(31.0%vs.32.1%,P=1.000)were not statistically significant between the observation group and the control group. Conclusions:PCI revascularization may be a viable approach for elderly patients with complex LM lesions with multiple underlying disease,and combined right coronary artery CTO,intolerance and reluctance to CABG.

Objectives:To analyze the safety of coronary artery stent rotational atherectomy due to stent underexpansion,in-stent restenosis,stent deformation,stent damage,and guide wire entrapment. Methods:A total of 19 patients with coronary artery disease who underwent coronary artery stent rotational atherectomy for the above reasons in 7 large heart centers in China from 2016 to 2022 were collected.Their baseline data,procedure process data,procedural complications,the occurrence of procedure-related adverse events(type 4a myocardial infarction,emergency coronary artery bypass grafting,and all-cause death)during hospitalization and major adverse cardiovascular events(MACE,including target vessel revascularization,stroke,all-cause death,and recurrent myocardial infarction)during post-discharge follow-up were retrospectively collected. Results:The mean age of the 19 patients was 70(64,73)years,and 13 patients were males.The mean left ventricular ejection fraction was(56.89±8.76)%.Radial artery approach was used in 13 patients,11 patients used 1 burr during the intervention period,6 patients used 2 burrs,and 2 patients used 3 burrs.The average times of burr passing through the lesion was(7.00±4.23)times.The surgical success rate was 100%,and the immediate lumen acquired area was(1.23±0.78)mm2.Drug-eluting stents were successfully implanted in all patients after spinning.Coronary slow blood flow occurred in 1 case after rotational grinding,which was improved after drug treatment.The burr was entrapmented in 3 cases and successfully pulled out after operation.No coronary artery perforation,coronary artery dissection,coronary artery spasm,emergency thoracotomy,or death occurred during the operation,and no procedure-related adverse events occurred during hospitalization.During 3 to 24 months of follow-up,1 patient underwent target vessel revascularization,and there were no MACE in other patients. Conclusions:Coronary artery stent rotational atherectomy in patients with stent underexpansion,in-stent restenosis,stent deformation,stent damage,and guide wire entrapment,is a feasible option,with a high surgical success rate and satisfactory safety.None of the patients experienced MACE during long-term follow-up.

Objective:To analyze the screening test results of people infected with human immunodeficiency virus (HIV) in the window period confirmed to be "negative" by Western blotting, with a view to finding a way to identify people infected with HIV during the window period as soon as possible.Methods:In the serum (plasma) samples of HIV-positive people screened by the fourth-generation chemiluminescent immunoassay in medical institutions at all levels in Pudong New District, Shanghai from 2014 to 2021, a total of 100 people (200 samples) were confirmed as "negative" and the fourth-generation enzyme-linked immunosorbent assay was screened positive. According to the follow-up results, it was divided into the early infection group (24 cases) and the uninfected group (76 people), and the fourth-generation rapid diagnostic test (RDT) was performed. The compliance rates of positive results of screening and follow-up were compared, and the epidemiological data of early HIV infections were analyzed. The chi-square test was used for statistical analysis.Results:Of the 200 samples, 48(24.00%) were early infected. A total of 106 samples antigens and (or) antibodies were positive by the fourth-generation RDT screening, and the compliance rate with the follow-up results was 45.28%(48/106), of which those of the fourth-generation RDT screening antigen positive and follow-up results were 100.00%(36/36), which was higher than the antibody positive results (24.68%(19/77)). The difference was statistically significant ( χ2=57.49, P<0.001). Of the 24 cases of early HIV infections, 19(79.2%) had acute symptoms. Only one out of six people≥50 years old had asked about the partner about his HIV status before engaging high-risk sex, and 13 out of 18 people <50 years old had asked the partners about their HIV status or to detect HIV before engaging high-risk sex. The difference was statistically significant ( χ2=5.71, P=0.017). Out of the six people ≥50 years old, only one actively tested HIV, and 12 out of 18 people <50 years old actively tested HIV, and the difference was statistically significant ( χ2=4.53, P=0.033). Conclusions:The Western blotting confirmed "negative" samples may be false negative. The comprehensive evaluation which combined with the fourth-generation screening test could help to screen out HIV window infection. In addition, the publicity, education and monitoring of high-risk population need to be further strengthened.

Objective:To investigate the impact of early blood glucose fluctuations after acute multiple injuries on post-traumatic stress disorder (PTSD).Methods:This study was a case-control study. From March 2022 to March 2023, patients with acute multiple injuries who were admitted to the ICU of the Affiliated Hospital of Xuzhou Medical University were selected. According to whether complicated with traumatic brain injury (TBI), the patients were divided into TBI group and non-TBI group. Early post-traumatic blood glucose fluctuations were observed, including stress-induced hyperglycemia (SIH), initial blood glucose value on admission, blood glucose extreme, short-term glycemic variability (GV) and other related indicators. The 72-hour glucose coefficient of variation (Glu-CV) was used to reflect short-term GV. After 1 month, the PTSD checklist for DSM-5 (PCL-5) was used to assess the patient's symptoms of PTSD. The patients were divided into PTSD group and non-PTSD group according to PCL-5 score ≥38. The differences in short-term glucose fluctuations in each groups were compared; the risk factors of PTSD were analyzed by logistic regression; the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of related indicators on the incidence of PTSD.Results:159 patients with acute multiple injuries were selected and defined as the TBI group ( n=94) and non-TBI group ( n=65). The incidence of PTSD, PCL-5 scale scores, the incidence of SIH and 72 h Glu-CV in the TBI group were significantly higher than the non-TBI group (all P<0.05). The incidence of SIH and 72 h Glu-CV in the PTSD group were significantly higher than the non-PTSD group (both P<0.05). Multivariate logistic regression analysis showed that 72 h Glu-CV ( OR=1.333, 95% CI: 1.028-1.727, P=0.030) was the independent risk factor for PTSD after acute multiple injuries, and the area under the ROC curve was 0.861 (95% CI: 0.789-0.933, P<0.001), the sensitivity was 62.9% and the specificity was 93.5%. Conclusion:Patients with acute multiple injuries with TBI are more likely to have early glucose fluctuations and develop PTSD, and increased short-term glucose variability is the independent risk factor for PTSD after acute multiple injuries.

Objective:To analyze the risk factors of internalizing problems in adolescents aged 12 to 18 years,and provide supporting evidence for the scientific prevention and effective control of internalizing problems in adolescents.Methods:By systematically searching the Chinese and English databases such as CNKI,VIP,Wan-fang,PubMed,Web of Science,Psychology and Behavioral Sciences Collection,PsycInfo,PsycArticles and ERIC,literature on risk factors of internalizing problems among adolescents in the past 22 years was collected,and non-clinical literature using CBCL or YSR or TRF scales to measure related internalizing problems were included.Meta analysis was performed using CMA3.0,with r as the effect size indicator and random effects model combined with the effect size of risk factors.Results:Finally,77 and 18 risk factors literatures were included,including 7 risk fac-tors of individuals,7 risk factors of family,and 4 risk factors of school/community.The average correlation between family risk factors and internalizing problems of adolescents was the highest.Among family risk factors,parent-child attachment had the highest correlation.Conclusion:Individual risk factors,family risk factors and school/com-munity risk factors are significantly positively correlated with adolescent internalizing problems,and family risk fac-tors(especially parent-child attachment quality)have the highest correlation with adolescent internalizing problems.
