AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

AIM: To observe the changes of corneal densitometry(CD)and higher-order aberrations after small incision lenticule extraction(SMILE), and to explore their correlations and influencing factors.METHODS: Prospective study. A total of 62 high-degree myopia and compound myopic astigmatism patients(62 eyes)who underwent SMILE in Urumqi Aier Eye Hospital from December 2022 to November 2023 were collected. The CD, root mean square of corneal higher-order aberrations(RMS HOA), spherical aberration, vertical coma, horizontal coma, and corneal epithelial thickness(CET)of the patients were measured before surgery, and at 1 d, 1 wk, 1, 3, and 6 mo after surgery, respectively.RESULTS:There were 4 patients lost to follow-up during the period, all due to failure to attend scheduled reexaminations. The number of complete and valid cases was 58 eyes. The CD in the central and paracentral regions of the anterior, middle, and total layer of the cornea increased significantly on the first day after surgery(all P<0.003). At 6 mo after surgery, there was a slight but statistically significant decrease in the CD of the central and paracentral regions of the anterior and the total anterior layer(all P<0.003). Compared with the preoperative baseline values, the RMS HOA, spherical aberration, and vertical coma significantly increased at 6 mo after surgery(all P<0.003), while the change in horizontal coma was not statistically significant. Compared with the preoperative baseline values, the CET in the central, paracentral, and peripheral regions of the cornea, as well as the total average CET in the 0-7 mm range of the cornea increased at 6 mo after surgery(all P<0.003). At 1 d after surgery, CD of the anterior layer and total layer in the central region of the cornea were positively correlated with the CET in the central region(rs=0.327, rs=0.250, all P<0.05). At 6 mo after the surgery, the CD of the middle layer and posterior layer in the central corneal region were negatively correlated with the preoperative spherical equivalent and the change of RMS HOA(all P<0.05).CONCLUSION:The anterior CD decreases at 6 mo after SMILE for high myopia correction, and there is a certain correlation between the changes in CD and some clinical parameters.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate serum levels of soluble apoptosis-related factor ligand(sFasL)and stromal cell derived factor 1(SDF-1)in patients with aplastic anemia(AA)and their correlation with immunosuppressive treatment.Methods Forty-three AA patients who received immunosuppressive therapy for half a year were selected as the observation group,and another 43 healthy subjects at the same period were selected as the control group.Patients in the observation group received immunosuppressive therapy and hematopoietic propoietic therapy,and patients were divided into the ineffective group and the effective group according to the efficacy.Clinical data of patients were collected,and serum levels of sFasL,SDF-1,tumor necrosis factor-α(TNF-α)and interleukin-8(IL-8)were detected by enzyme-linked immunosorbent assay.The correlation between serum sFasL and SDF-1 levels was analyzed.Multivariate Logistic regression analysis was conducted to analyze influencing factors of immunosuppressive treatment in AA patients.The predictive values of serum sFasL and SDF-1 on immunosuppressive treatment were analyzed by receiver operating characteristic(ROC)curve.Results Serum levels of sFasL and SDF-1 were higher in the observation group than those in the control group(P＜0.05).Serum levels of TNF-α,IL-8,sFasL and SDF-1 were higher in the ineffective group than those in the effective group(P＜0.05).Serum sFasL level was positively correlated with SDF-1 level in AA patients(r=0.534,P＜0.001).Increased serum sFasL and SDF-1 levels were independent risk factors for ineffective immunosuppressive therapy in AA patients(P＜0.05).The area under the curve(AUC)of serum sFasL and SDF-1 combined to predict the immunosuppressive treatment effect of AA patients was 0.973(95%CI:0.872-0.999),which was better than that of single diagnosis(P＜0.05),and its sensitivity and specificity were 94.44%and 96.00%,respectively.Conclusion Serum levels of sFasL and SDF-1 are significantly increased in patients with AA.The combined detection of sFasL and SDF-1 has high predictive value for the immunosuppressive treatment effect of AA.

Objective:To compare the efficacy and safety of transcatheter arterial embolization (TAE) and Viabahn covered stent placement (CSP) for the treatment of delayed hemorrhage after hepatobiliary and pancreatic surgery (DH-HPS).Methods:The clinical data of 41 patients with DH-HPS at the Affiliated Hospital of Xuzhou Medical University from January 2019 to June 2023 were retrospectively analyzed. Among these patients, 27 were male and 14 were female, with an average age of (63.1±10.3) years. 22 patients who underwent TAE was in TAE group and 19 who underwent Viabahn CSP was in CSP group. The interventional treatment effect, blood biochemical indexes and complications were compared between the two groups.Results:In the TAE group, the success rate of hemostasis was 90.9% (20/22), and the rebleeding rate was 9.1% (2/22) after interventional treatment. In the CSP group, the success rate of hemostasis was 94.7% (18/19), and the rebleeding rate of was 5.3% (1/19) after interventional treatment. There was no statistically significant difference in the success rate of hemostasis and the rebleeding rate between the two groups (both P>0.05). The rate of liver function exacerbation after the procedure was 100% (20/20) in the TAE group and 58.8% (10/17) in the CSP group, with a statistically significant difference between the two groups ( χ2=9.77, P=0.002). 37 patients were followed up (18.4±1.7) months, and no rebleeding occurred in all patients. Conclusion:TAE and CSP are both effective for DH-HPS, while CSP is superior to TAE in terms of liver function protection.

Objective:To explore the potential causal relationship between gut microbiota and teratozoospermia.Methods:We searched the database of Genome-Wide Association Study(GWAS)for gut microbiota-and teratozoospermia-related data.We used gut microbiota as an exposure factor,determined the instrumental variables according to the GWAS data on 18 340 participants released by the MiBioGen Alliance,and derived the outcome variables from the European data on teratozoospermia,with a sample size of 85 716,including 915 cases and 209 006 controls.Using inverse-variance weighting(IVW),MR-Egger regression and the weighted median estimator(WME),we performed two-sample Mendelian randomization(MR)analysis on the retrieved data,and estimated the causal relationship between gut microbiota and teratozoospermia based on the β value.Results:Two-sample MR analysis indicated that the class Erysipelotrichia,family Erysipelotrichaceae,family Streptococcaceae,genus Coprococcusl,genus Ruminococcaceae UCG009,genus Streptococcus,order Clostridialesm and order Erysipelotrichales were causally related with the increased risk,while the family Porphyromonadaceae with the decreased risk of teratozoospermia.Conclusion:The class Erysipelotrichia,family Erysipe-lotrichaceae,family Streptococcaceae,genus Coprococcusl,genus Ruminococcaceae UCG009,genus Streptococcus,order Clostridia-lesm and order Erysipelotrichales are one of the causes of teratozoospermia,related to the increased risk of the condition,while the family Porphyromonadaceae has a protective effect on sperm morphology,reducing the risk of teratozoospermia.

Objective:To evaluate the clinical efficacy of Xiaozheng Granules(XZG)combined with Jingqiankang Bacterio-static Gelatin(JBG)on chronic prostatitis of the damp-heat and blood-stasis type based on infrared thermography(IRT).Methods:This study included 120 cases of chronic prostatitis with damp-heat and blood stasis treated in the First Affiliated Hospital of Henan U-niversity of Chinese Medicine with oral XZG(the control group,n=60)or oral XZG combined with anal administration of JBG(the trial group,n=60),both for 4 weeks.We obtained the NIH-CPSI and traditional Chinese medicine(TCM)syndrome scores of the patients,measured the temperatures in the belt-vessel,lower focal and inguinal regions by IRT before and after treatment,recorded the adverse reactions during the treatment,and compared them between the two groups of patients.Results:Compared with the base-line,the NIH-CPSI and TCM syndrome scores were significantly decreased in the two groups of patients after treatment(P<0.05),even more significantly in the trial than in the control group(P<0.05),and after 1 hour of treatment,the temperatures in the Xia-jiao([34.09±0.34]vs[33.60±0.40]℃,P<0.05)and the groin region([34.49±0.28]vs[33.78±0.30]℃,P<0.05)were remarkably reduced in the trial group,but showed no significant change in the control group(Xiajiao region:[34.02±0.29]vs[34.05±0.26]℃,P>0.05;groin region:[34.54±0.25]vs[34.51±0.22]℃,P>0.05).After 4 weeks of treatment,the temperatures in the Xiajiao and groin regions were even lower in the trial([33.13±0.41]℃ and[33.21±0.29]℃ )and the control group([33.42±0.25]℃ and[33.86±0.29]℃ )than the baseline and those after 1 hour of treatment(P<0.05),and still more significantly in the former than in the latter group(P<0.05).The total effectiveness rate was markedly higher in the trial group than in the control(88.14％ vs 77.19％,P<0.05),and no obvious adverse reactions were observed in neither group.Conclusion:XZG combined with JBG is a safe and effective treatment of chronic prostatitis with damp-heat and blood-stasis,which can significantly reduce the NIH-CPSI and TCM syndrome scores and IRT temperatures in the lower focal and in-guinal regions of the patients.

Objective: To explore the association between cardiometabolic diseases (CMD) and quality of life, the association between CMD and perceived stress, and the mediation effect of perceived stress on the association between CMD and quality of life, and to provide evidence for the prevention and treatment of CMD and the improvement of quality of life in these patients. Methods: This is a cross-sectional study. Data were collected by the employees' physical examination of a company in Xi'an in 2021. Multiple linear regression models were used to analyze the association between the status of CMD (divided into three categories: no CMD, presence of one kind of CMD, and with≥2 kinds of CMD (≥2 kinds of CMD were defined as cardiometabolic multimorbidity (CMM)), quality of life, and perceived stress. Mediation analysis with a multi-categorical independent variable was conducted to determine the mediation effect of perceived stress on the association between CMD and quality of life. Results: Among all 4 272 participants, 1 457 (34.1%) participants had one kind of CMD and 677 (15.8%) participants had CMM. The average scores for quality of life and perceived stress were (57.5±15.7) and (16.9±7.9), respectively. Compared with participants without CMD, after adjusting for demographic and lifestyle factors, no statistically significant associations were observed between one kind of CMD and perceived stress or quality of life (both P>0.05). Perceived stress did not mediate the association between one kind of CMD and quality of life. However, participants with CMM had lower quality of life and higher perceived stress than participants without CMD. The relative total effect coefficient c (95%CI) and the relative direct effect coefficient c' (95%CI) between CMM and quality of life were -3.71 (-5.04--2.37) and -2.52 (-3.81--1.24) (both P<0.05), respectively. The relative indirect effect coefficient a₂b (95%CI) of perceived stress on the association between CMM and quality of life was -1.18 (-1.62--0.77) (P<0.05). The mediation effect size was 31.8%. Conclusions: CMM is negatively associated with quality of life and positively associated with perceived stress. Perceived stress partially mediates the association between CMM and quality of life. Our results suggest that, in addition to preventing and treating CMM actively, efforts should be taken to relieve the perceived stress of people with CMM to improve their quality of life.

Objective: To analyze the survival time of reported HIV/AIDS and influencing factors of Yunnan Province from 1989 to 2021. Methods: The data were extracted from the Chinese HIV/AIDS comprehensive response information management system. The retrospective cohort study was conducted. The life table method was applied to calculate the survival probability. Kaplan-Meier was used to draw survival curves in different situations. Furthermore, the Cox proportion hazard regression model was constructed to identify the factors related to survival time. Results: Of the 174 510 HIV/AIDS, the all-cause mortality density was 4.23 per 100 person-years, the median survival time was 20.00 (95%CI:19.52-20.48) years, and the cumulative survival rates in 1, 10, 20, and 30 years were 90.75%, 67.50%, 47.93% and 30.85%. Multivariate Cox proportional risk regression model results showed that the risk of death among 0-14 and 15-49 years old groups were 0.44 (95%CI: 0.34-0.56) times and 0.51 (95%CI:0.50-0.52) times of ≥50 years old groups. The risk for death among the first CD4⁺T lymphocytes counts (CD4) counts levels of 200-349 cells/μl, 350-500 cells/μl and ≥501 cells/μl groups were 0.52 (95%CI: 0.50-0.53) times, 0.41 (95%CI: 0.40-0.42) times and 0.35 (95%CI: 0.34-0.36) times of 0-199 cells/μl groups. The risk of death among the cases that have not received antiretroviral therapy (ART) was 11.56 (95%CI: 11.26-11.87) times. The risk for death among the cases losing to ART, stopping to ART, both losing and stopping ART was 1.66 (95%CI:1.61-1.72) times, 2.49 (95%CI:2.39-2.60) times, and 1.65 (95%CI:1.53-1.78) times of the cases on ART. Conclusions: The influencing factors for the survival time of HIV/AIDS cases were age at diagnosis in Yunnan province from 1989 to 2021. The first CD4 counts levels, antiretroviral therapy, and ART compliance. Early diagnosis, early antiretroviral therapy, and increasing ART compliance could extend the survival time of HIV/AIDS cases.

Blood loss and blood transfusion requirement are important quality control indicators of cardiovascular surgery and cardiovascular anesthesia. Patient blood management (PBM) is an evidence-based, multidisciplinary approach to optimizing the care of patients who may need transfusion, which encompasses anemia management, hemodilution, cell salvage, hemostatic treatment, and other approaches to reducing bleeding and minimizing blood transfusion. PBM in cardiovascular surgery is a "team sport" that involves cardiac and vascular surgeons, anesthesiologists, perfusionist, intensivists, and other health care providers. The current work provides an overview of evidence and practice of PBM at Fuwai Hospital. Implementation of PBM should also take local resource availability and cost-effectiveness of different devices, drugs, technologies, and techniques into consideration.
