Objective:To investigate the factors related to the occurrence of submacular fluid (SMF) after pars plana vitrectomy (PPV) in the treatment of rhegmatogenous retinal detachment (RRD).Methods:A retrospective case series observational study was performed.A total of 103 patients (103 eyes) with RRD who underwent 23G vitrectomy combined with silicone oil tamponade in The First Affiliated Hospital of Zhengzhou University from May 2017 to August 2019 were included.There were 55 males and 48 females, aged from 17 to 77, with an average of (48.65±15.80) years.The macular morphology was observed by optical coherence tomography (OCT) before surgery and 1 month and 3 months after surgery.The patients were divided into SMF group and no SMF group according to OCT results at 1 month after surgery.Clinical data were compared and analyzed, including age, gender, duration of symptoms, axial length, the preoperative status of macula (on or off), retinal detachment caused by inferior retinal break or not, the way to drain subretinal fluid intraoperative, best corrected visual acuity (BCVA). FFA was performed in 3 eyes and microperimeter examination in 2 eyes with SMF according to patients' willingness.A multivariate binary Logistic regression was used to analyze the risk factors of SMF after vitrectomy in RRD patients.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of The First Affiliated Hospital of Zhengzhou University (No.2020-KY-334). Written informed consent was obtained from each subject prior to surgery.Results:Postoperative optical fundus examination and ocular ultrasound indicated that retinas of all eyes were completely anatomically reattached.There were 10.7% (11/103) of eyes developed SMF.The microperimeter examination results of 2 patients showed that their visual functions were worse at 3 months than those at 1 month after operation.The BCVA of patients with SMF at 1 month and 3 months after operation were worse than those without SMF, and the differences were statistically significant (both at P<0.05). Logistic regression analysis showed that macula-off RD before surgery and RD caused by inferior break of retina were risk factors for the occurrence of SMF (OR=6.401, P=0.041; OR=19.819, P=0.005), while the increasing age and the drainage of subretinal fluid through draining hole were protective factors (OR=0.939, P=0.016; OR=0.123, P=0.040).Conclusions:Macula-off RD before surgery, and RD caused by inferior break of retina may be the risk factors of SMF after PPV combined with silicone oil tamponade for RRD.Nevertheless, the increasing age and the drainage of subretinal fluid through draining hole may decrease the occurrence of SMF.And SMF after PPV may delay visual recovery.

[ABSTRACT]OBJECTIVETo diagnose laryngopharyngeal reflux (LPR) by using two methods: 24h pH monitoring and RSI combined with RFS scales. To research the voice characteristics of patients with LPR and changes of voice parameters before and after PPIs therapy, and to use voice parameters to help diagnosing and evaluating treatment effect of LPR.METHODSThe patients visited department of Otolaryngology head & neck surgery of Peking University Third Hospital from August 2012 to August 2013 were included in this study. There were 26 LPR patients diagnosed by 24 hr pH-MII monitoring (pH group) and 26 LPR patients diagnosed by RSI combined with RFS (questionnaire group). Another 52 subjects without laryngeal or pharyngeal symptoms were as control group. All subjects underwent MDVP examination. The patients from pH group and questionnaire group took esomeprazole 20 mg bid for one month, afterwards MDVP was examined again. The voice related parameters were compared before and after medication therapy.RESULTSComparing data between LPR patients and normal subjects, Jitter, Shimmer, NHR had significant difference (P<0.05), and F0, MPT had no significant difference (P>0.05) before treatment. After PPIs therapy there was no significant difference between each group (P>0.05).CONCLUSIONAbnormal voice parameters were existed in LPR patients. After PPIs treatment, voice related parameters improved apparently.

Objective:To evaluate the safety and efficacy of amniotic membrane patching in the treatment of recurrent macular hole associated with retinal detachment of high myopia (MHRD).Methods:A prospective study. From March 2018 to January 2020, 11 patients (11 eyes) of recurrent macular hole associated with MHRD at the First Affiliated Hospital of Zhengzhou University were enrolled. Among them, there were 3 males (3 eyes), and 8 females (8 eyes). The average age was 63.64±5.82. The axis length (AL) was 29.10± 0.59 mm, and the logarithm of the minimum angle of resolution best corrected visual acuity (logMAR BCVA) was 2.23±0.57. Patients previously received pars plana vitrectomy (PPV) combined with internal limiting membrane stripping surgery, which was more than 1 time. All eyes underwent standard pars plana three-channel 23G PPV combined with amniotic membrane covering and silicone oil filling. The silicone oil was removed 6 months after surgery. Follow-up time was up to 3 months after silicone oil removal surgery. 1, 3, and 6 months after the operation, the same equipment and methods were used to conduct relevant examinations before the operation to observe the closure of the macular hole, retinal reattachment and changes in logMAR BCVA. The logMAR BCVA before and after surgery was compared by paired t test. Results:At 1, 3, and 6 months after the operation, the retinas of all eyes were anatomically repositioned, the macular holes were well closed, and the amniotic membrane was attached to the retina. At 3 months after the silicone oil removal operation, there was no recurrence of macular hole in all eyes; logMAR BCVA was 1.35±0.32. No serious complications occurred during and after surgery in all eyes.Conclusion:Amniotic membrane patching is a safe and effective method for recurrent macular hole associated with MHRD.

Objective:To observe the changes in the biomechanical properties of the cornea of diabetic retinopathy (DR), and analyze its relationship with the degree of DR.Methods:A retrospective study. From September 2020 to February 2021, 83 patients with type 2 diabetes (T2DM) combined with DR treated in the Department of Ophthalmology, The First Affiliated Hospital of Zhengzhou University, 83 eyes (DR group), 30 patients with T2DM without DR recruited from the outpatient clinic 30 eyes (NDR group) and 30 eyes of non-diabetes patients (NDM group) were included in the study. All left eyes were chose as the study eye. Among the 83 eyes in the DR group, 39 eyes were non-proliferative DR (NPDR) and 44 eyes were proliferative DR (PDR). Based on this, they were divided into NPDR group and PDR group. There was no statistically significant difference in age ( t=1.10) and sex ratio ( χ2=0.46) among patients in the DR group, NDR group, and NDM group ( P>0.05); body mass index ( t=3.74), glycosylated hemoglobin ( t=35.02) and the length of the eye axis ( t=5.51), the difference was statistically significant ( P<0.05). The eye response analyzer (ORA) was used to measure the corneal hysteresis (CH), corneal resistance factor (CRF), Goldman related intraocular pressure (IOPg), and corneal compensatory intraocular pressure (IOPcc). The corneal topography was used to measure the central corneal thickness (CCT) of the examined eye. The differences of CCT, IOPcc, IOPg, CH, CRF among multiple groups were compared by one-way analysis of variance. Multiple linear regression was used to analyze the relationship between CH, CRF and related influencing factors in DR patients. Results:There were statistically significant differences in CCT, IOPcc, IOPg, CH, and CRF among the eyes of the DR group, NDR group, and NDM group ( F=3.71, 5.60, 9.72, 9.02, 21.97; P<0.05). Pairwise comparisons were between groups, CH, CRF: the difference between the DR group and the NDM group and the NDR group was statistically significant ( P<0.05); CCT: the difference between the DR group and the NDM group was statistically significant ( P<0.05), and The difference in the NDR group was not statistically significant ( P>0.05). CCT, CH, CRF: the difference between the NDR group and the NDM group was not statistically significant ( P>0.05). The results of multiple linear regression analysis showed that CCT and IOPcc in DR patients were independent influencing factors of CH [CCT: β=0.01, 95% confidence interval ( CI) 0.01-0.03, P=0.013; IOPcc: β=-0.15, 95% CI -0.25--0.05, P=0.005]; Age, CCT, IOPcc were independent influencing factors of CRF [Age: β=-0.06, 95% CI -0.09--0.03, P<0.001; CCT: β=0.01, 95% CI 0.00-0.02, P=0.049; IOPcc: β=0.16, 95% CI 0.07-0.25, P=0.001]. The comparison of CCT, CH, CRF, adjusted CH, and adjusted CRF of the eyes in the NDR group, NPDR group, and PDR group were statistically significant ( F=3.76, 5.36, 12.61, 6.59, 10.41; P<0.05). Pairwise comparison between groups, CH, CRF, adjusted CH, adjusted CRF: the difference between the NPDR group, the PDR group and the NDR group was statistically significant ( P<0.05), and the difference between the PDR group and the NPDR group was not statistically significant ( P>0.05); CCT: The difference between NPDR group and NDR group, PDR group and NPDR group was not statistically significant ( P>0.05), and the difference between PDR group and NDR group was statistically significant ( P<0.05). Conclusion:The CH and CRF of eyes with T2DM and DR are elevated; CCT and IOPcc are independent influencing factors of CH, and age, CCT and IOPcc are independent influencing factors of CRF.

Objective:To evaluate the effect of intraoperative incision combined with local anesthesia in improving postoperative pain after retroperitoneal laparoscopic living donor nephrectomy.Methods:Using retrospective research methods, 28 donors who underwent hand-assisted retroperitoneal laparoscopic living donor nephrectomy at the Beijing Friendship Hospital, Capital Medical University from January 2018 to December 2020 were selected as the research group. Before the wound was sutured during the operation use 0.2% ropivacaine 20 mL+ 5 mg dexamethasone to block the transverse abdominis fascia and subcutaneously for infiltration anesthesia. The other 1∶1 matched 28 donors who had the same operation method but used on-demand systemic opioid analgesia after the operation as the control group. The demographic indicators (age, gender, body mass index, length of donor kidney), intraoperative conditions (intraoperative blood loss, operation time, warm ischemia time), 2, 12, 24, and 48 hours pain visual analogue scales(VAS) after operation were compared between the two groups of patients, postoperative systemic opioid demand rate, postoperative exhaust time, time to return to the ground, complication rate (postoperative bleeding, lung infection, lymphatic fistula, wound infection, intestinal obstruction), postoperative length of hospitalization and other information. Measurement data were expressed as mean±standard deviation ( Mean± SD), and independent sample t-test was used for comparison between groups; Chi-square test or Fisher exact probability method was used for comparison of count data between groups. Results:The pain VAS of the donors in the research group were significantly lower than those in the control group at 2 h, 12 h, 24 h, and 48 h after surgery (2 h: 1.6±1.0 vs 3.9±1.1; 12 h: 1.9±0.7 vs 3.1±1.0; 24 h: 1.6±0.5 vs 2.9±0.8; 48 h: 1.2±0.5 vs 2.3±0.8; P<0.05). The donors in the research group postoperative morphine requirement rate was also significantly lower than that of the control group (0 vs 21.4%), and the postoperative recovery time was significantly earlier than that of the control group [(25.7±4.5) h vs (30.6±6.6) h], the difference was statistically significant ( P<0.05). Lymphatic fistula was the main postoperative complication. There was no statistically significant difference between the research group and the control group (14.3% vs 25.0%) ( P>0.05). Conclusion:Intraoperative incision transversus abdominis fascia and subcutaneous combined local block anesthesia can effectively reduce the pain after laparoscopic donor nephrectomy, reduce the use of opioids, promote early postoperative activities of the donor, and will not increase postoperative complications incidence rate.

Objective To construct a regulatory network of competing endogenous RNA(ceRNA)with prognostic value for bladder urothelial carcinoma(BLCA),and analyze the relationship between key messenger RNA(mRNA)and immune function.Methods The UCSC Xena database was used to download mRNA expression data from 404 BLCA patients and 28 normal individuals and key mRNAs were screened by differential analysis.ENCORI database was utilized to search microRNAs(miRNAs)that bind to key mRNAs and all long non-coding RNAs(LncRNAs)that bind to miRNAs.The expression data of miRNA and LncRNA were downloaded from TCGA database,co-expression analysis was performed to identify key mRNA with all miRNAs and miRNA with all LncRNAs,and thus key miRNAs and LncRNAs were screened out.Survival analysis was conducted based on the differences in expression levels of these key mRNAs,miRNAs,and LncRNAs between tumor patients and normal individuals,and finally a ceRNA regulatory network was constructed.The correlation between key mRNAs and immune cells,immune checkpoints(CD274,PDCD1 and CTLA4),and immune cell marker genes(IG)was analyzed using the TIMER 2.0 database.Results A total of 22 key mRNAs were screened,with the most significant difference being proline 3-hydroxylase 4(P3H4).The expression of P3H4 in patients with BLCA was high,and survival time was shorter in patients with high expression.A sum of 33 miRNAs and 14 LncRNAs were screened using the key mRNAs as the central link.Through co-expression analysis and survival analysis,hsa-miR-151a-3p and MIR100 HG were identified as the key miRNA and key LncRNA with prognostic value.The differences in the above analysis results were statistically significant(all P＜0.05).Based on these findings,a ceRNA regulatory network consisting of 1 mRNA,1 miRNA,and 1 LncRNA was constructed.Immunoassay firstly revealed a significant positive correlation between double positive T cells and P3H4 expression in the tumor microenvironment of BLCA.Moreover,there were 3 types of immune cells(tumor-associated neutrophils,and tumor-associated macrophages,dendritic cells),3 immune checkpoints(CD274,PDCD1,CTLA4),and 15 IGs with significant correlation with P3H4.These differences were statistically significant(all P＜0.01).Conclusion This study could help to reveal the progression mechanism of BLCA.The constructed ceRNA network and immune analysis can offer new insights into potential biological targets and immunotherapy directions for the diagnosis,treatment,and prediction of BLCA patients.

Objective    To compare and analyze the postoperative quality of life in patients after minimally invasive coronary artery bypass grafting (MICABG) and conventional median thoracotomy off-pump coronary artery bypass grafting surgery (OPCABG). Methods    From November 2015 to January 2018, 94 patients who underwent MICABG in the Peking University Third Hospital were included in the MICABG group. During the same period 441 patients who received OPCABG were included in the OPCABG group. The patients were matched by using propensity score matching method with a ratio of 1∶1. The quality of life was compared between two groups at 1 month, 6 months and 12 months after the surgery using SF-36 scale. Results    A total of 82 patients were matched for each group. In the MICABG group, there were 66 males and 16 females with a mean age of 62.6±8.2 years. In the OPCABG group, there were 67 males and 15 females with a mean age of 63.2±13.2 years. One month after the operation, the physical health assessment (PCS) and mental health assessment (MCS) of the MICABG group were higher than those of the OPCABG group (50.3±10.6 points vs. 46.1±10.3 points, P=0.011; 59.5±9.3 points vs. 54.2±11.0 points, P=0.002). Scores of these following five dimensions: general health, physical functioning (PF), role-physical, social functioning (SF), role-emotion in the MICABG group were higher than those in the OPCABG group, while the score of body pain was inferior to that in the OPCABG group, and the differences were statistically significant (P<0.05). Six months after the surgery, the PCS and MCS of the two groups were not statistically different (80.0±13.1 points vs. 77.8±12.4 points, P=0.271; 81.6±13.5 points vs. 80.4±11.2 points, P=0.537). However, the scores of PF and SF in the MICABG group were still higher than those in the OPCABG group (P<0.05). Twelve months after the surgery, there was no statistical difference in the score of each dimension between the two groups (P>0.05). Conclusion    The improvement of quality of life within 6 months after MICABG is better than that of OPCABG, and it is similar between the two groups at 12 months after the surgery, indicating that MICABG has a certain effect of improving the short-term quality of life after the surgery, and the long-term quality of life is comparable to conventional surgery.
