Objective To investigate the technical difficulties and the avoidance of complications in delayed laparoscopic cholecystectomy (LC) for acute cholecystitis (AC).MethodsThe results of LC carried out on 133 consecutive patients with AC between February 2004 and August 2008 were retrospectively studied.The outcomes were compared between patients who received LC for AC within 72 hours (the early group) and those after 72 hours (the delayed group).There were 34 patients in the early group and 99 in the delayed group.During LC,Calot's triangle was carefully dissected,and the relationship of the cystic duct to the CBD and common hepatic duct was clearly identified.Retrograde cholecystectomy in 2 patients was used when the Calot's triangle was poorly identified.Laparoscopic subtotal cholecystectomy was carried out in 4 patients whose inflammation or fibrosis precluded dissection of the Calot's triangle.ResultsThere was no conversion to open cholecystectomy,biliary tract injury,biliary leak,or any other intraoperative or postoperative complications.There was no 30day readmission in the 2 groups.Patients who received delayed LC had a significantly longer operation time [(44.1±5.32) vs (66.4±3.05)rnin,P＜0.01].There was no significant difference in wound infection rates in the 2 groups (1/34 2.94 ％ vs 2/99 2.02 ％,P＞0.05).ConclusionsDelayed LC was as feasible and safe as early LC in the treatment of AC.Delayed LC was technically more demanding than early LC.

ObjectiveTo evaluate treatment of type 2 diabetes mellitus (T2DM) by laparoscopic Roux-en-Y gastric bypass (LRYGB) using different amastomoses. MethodsTwenty one T2DM patients were divided into two groups:transoral EEA (OrVil) and Endo-GIA according to ways of gastrointestinal anatomosis andunderwentLRYGB. Clinicaldataincluding outcomeof operation, complications,preoperative and postoperative oral glucose tolerance test (OGTT),Homa-IR,Homa-β,blood lipid and nutrition status were analyzed.ResultsLRYGB procedures were successfully performed in all the 21 patients with no conversion to open surgery.The difference of intraoperative blood loss,postoperative recovery time between two groups was not significant.The mean operation time in OrVil group ( 126 ± 29 )mins was shorter than that in Endo-GIA group ( 156 ± 28 ) mins ( P ＜ 0.05 ),but at the same time,the mean expenditure was higher. Evaluated on three months after operation,the T2DM cure rate was 78％,and effective rate was 100％ in OrVil goup and those were 83％,100％ respectively in Endo-GIA group.No postoperative malnutrition, anemia or severe complication occurred.ConclusionsThe efficiency of laparoscopic Roux-en-Y gastric bypass using different amastomoses was same in the treatment of type 2 diabetes mellitus.The operation time was shorter in OrVil group but the expenditure was higher.

Under the"Internet +" era, some medical staff' s treatment philosophy cannot adapt to the current situation, and patients are prone to produce high expectations because of inadequate basic medical knowledge and the habit of acquiring medical information from Internet. However, when the difference between reality and expec-tations are large, they might be in disputes with medical staffs, and coupled with the lag of hospital management, the doctor-patient communication often is not smooth situation. Therefore, it is recommended that medical staffs improve humanistic quality meanwhile improving technology, patients should develop the habit of acquiring medical information from Internet correctly, hospital needs to optimize management and allocate medical resource reasona-bly, and society should also create positive atmosphere.

OBJECTIVE To identify the mental state of laryngopharyngeal reflux disease (LPRD) patients by analyzing anxiety scale and depression scale. METHODS The LPRD patients who received treatment in Fuzhou General Hospital were studied. The healthy volunteers were recruited as control group. Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were used to get the individual scores. Mental states of LPRD patients were finally studied through statistical analysis. RESULTS The scores of anxiety and depression in patients with LPRD were significantly higher than those in control group (anxiety score 50.59±7.24 vs 38.76±7.70, depression score 52.90±7.14 vs 40.63±8.17). The incidence of anxiety and depression in patients with LPRD were significantly higher than that in control group (anxiety rate 56.68％ vs 9.80％, depression rate 50.98％ vs 11.76％). Significant association was detected between ref lux symptom index score and anxiety or depression score in patients with LPRD(r =0.786, r =0.736, P ＜0.05). Significant association between LPRD and anxiety and depression were concluded. CONCLUSION The results showed that the patients with LPRD are more prone to be anxiety and depression mental state than healthy control group, and the severity of LPRD symptoms is significantly correlated with the anxiety and depression. This suggests that the patient's mental state should also be emphasized as well as antacids treatment.

This study was aimed to explore the renoprotective effects of Tang-Shen-Ping (TSP) on RhoA/ROCK signaling pathway in KKAy mice with diabetic kidney disease (DKD).A total of 60 female 10-week SPF degree KKAy mice,which were fed with KK special food for 10 weeks,were made into DKD model.Mice were randomly divided in the model group,irbesartan group,low-,medium-and high-dose TSP group (0.525 g· kg-1,1.05 g· kg-1,and 2.1 g· kg-1).Ten female C57BL/6J mice were used as the normal control group.Mice of each group were intragastrically administered with corresponding medicine,respectively,while mice of the control group and the model group were given deionized water of the equal volume.The body weight was measured and the 24-hour urine protein quantification was detected every 4 weeks.At the end of the 26th week,all mice were sacrificed and the biochemical indicators,such as fasting blood glucose (FBG),serum blood urea nitrogen (BUN),serum creatinine (Scr),and triglyceride (TG) were measured.HE staining,Mallory staining and PAS staining were used to observe the pathological morphology of kidney tissues.Immunohistochemistry (IHC) and in situ hybridization (ISH) were used in the detection of transforming growth factor-β1 (TGF-β1),Ras homolog gene family member A (RhoA),Rho-associated coiled-coil-containing protein kinase 1 (ROCK1),α-smooth muscle actin (α-SMA),E-Cadherin (E-Cad) mRNA and protein expression.The results showed that compared with the model group,there were significant differences on body weight,the ratio of kidney weight to body weight,and urinary protein in the middle-and high-dose TSP group (P ＜ 0.01);the renal pathological damage was obviously decreased;contents of FBG,BUN,Scr and TG decreased (P ＜ 0.01);mRNA and protein expression of E-Cadherin increased;mRNA and protein expression of TGF-β1,RhoA,ROCK1 and α-SMA decreased with significant difference in the middle-and high-dosc TSP group (P ＜ 0.01).It was concluded that the renoprotective effects and epithelial-mesenchymal transdifferentiation (EMT) of renal tubular epithelial cells of TSP on DKD KKAy mice may be related to the regulation of RhoA/ROCK signaling pathway.

Objective To assess changes of blood flow density of idiopathic choroidal neovascularization (ICNV) treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF).Methods Retrospective case analysis.Sixteen eyes of 16 patients with ICNV diagnosed with FFA and OCT were included in this study.Among them,12 were female and 4 were male.The mean age was 33.94±9.83 years.The mean course of diseases was 5.13 ±4.44 weeks.The BCVA,indirect ophthalmoscope,OCT and OCT angiography (OCTA) were performed at the first diagnosis in all patients.The BCVA was converted to logMAR.The macular fovea retinal thickness (CMT) was measured by OCT,and the selected area of CNV (CSA) and flow area of CNV (CFA) were measured by OCTA.The mean logMAR BCVA,CMT,CSA and CFA were 0.336±0.163,268.500±57.927 μm,0.651 ±0.521 mm2,0.327±0.278 mm2,respectively.All patients were treated with intravitreal ranibizumab (IVR,10 mg/ml,0.05 ml).Follow-up results including the BCVA,fundus color photography,OCT and OCTA were obtained 1 month after treatment.To compare the changes ofBCVA,CMT,CSA,CFA of ICNV treated with anti-VEGF.Pearson method was used to analyze the correlation between logMAR BCVA and CMT,CSA and CFA before and after the treatment.Results One month after treatment,the average logMAR BCVA,CMT,CSA and CFA were 0.176±0.111,232.500± 18.910 μm,0.420±0.439 mm2,0.215 ± 0.274 mm2.The mean logMAR BCVA (t=5.471,P＜ 0.001),CMT (t=2.527,P=0.023),CSA (t=4.039,P=0.001),CFA (t=4.214,P=0.001) significantly decreased at 1 month after injection compared to baseline,and the difference had statistical significance.The results of correlation analysis showed that the post-logMAR BCVA was moderately positively correlated with pre-CSA and post-CSA (r=0.553,0.560;P=0.026,0.024),and strongly correlated with pre-CFA and post-CFA (r=0.669,0.606;P=0.005,0.013),but not correlated with preCMT and post-CMT (r=0.553,0.560;P=0.026,0.024).Conclusion The blood flow density of ICNV measured by OCTA were significantly decreased in the treatment of anti-VEGF drugs.

Objective:To analyze the peripheral retinal fluorescence characteristics of normal fundus on ultra-wide field fluorescein angiography (UWFA) images.Methods:A cross-sectional study was conducted.Ninety-five patients (190 eyes) who underwent normal UWFA in Renmin Hospital of Wuhan University from July 2016 to January 2019 were enrolled.There were 94 (49.47%) male eyes and 96 (50.53%) female eyes.Among them, there were 72 (37.89%) mild cataract eyes, 60 (31.58%) moderate and low myopia eyes and 58 (30.53%) subjective blurred vision eyes.The peripheral retinal fluorescence characteristics were divided into vascular-associated feature or non-vascular feature according to whether the retinal vessel involved or not.The subjects were divided into ≤40 years old group and >40 years old group, and the differences in various features between the two groups were compared and analyzed.The study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2019-K037). Written informed consent was obtained from each patient prior to any examination.Results:Four non-vascular and five vascular-associated fluorescence features were found in normal peripheral retina.Non-vascular features contained glass hyperfluorescence in 158 (83.16%) eyes, far peripheral retina with mottled florescent band in 82 (43.16%) eyes, granular ground hyperfluorescence in 24 (12.63%) eyes and local mottled fluorescence in 21 (11.05%) eyes.Vascular-associated fluorescence features included peripheral avascular area in 92 (48.42%) eyes, vessels passing through the ora serrata in 66 (34.74%) eyes, microaneurysm in 60 (31.58%) eyes, slight leakage within 10 minutes after angiography in 56 (29.47%) eyes and angiotelectasis in 30 (15.79%) eyes.There were 19.61% (20/102) of eyes with peripheral retinal vessels passing through the ora serrata and 43.10% (44/102) of eyes with microaneurysm and 19.61% (20/102) of eyes with angiotelectasis in >40 years old group, and there were 52.27% (46/88), 18.23% (16/88) and 11.36% (10/88) correspondingly in ≤40 years old group, and the differences were statistically significant ( χ2=22.235, 10.451, 9.259; all at P<0.01). Conclusions:UWFA reveals four non-vascular and five vascular-associated fluorescence characteristics of normal fundus and age might be associated with the distribution of microaneurysm and angiotelectasis.

Objective:To investigate the features of multicolor imaging in the macular region of central serous chorioretinopathy (CSC) patients.Methods:A cross-sectional study was conducted.Thirty-four acute CSC patients (34 eyes) treated in Renmin Hospital of Wuhan University from August 2017 to January 2018 were enrolled.Among the 34 subjects, there were 21 males (21 eyes) and 13 females (13 eyes). The subjects were 26 to 61 years old, with an average age of (37.41±9.35) years.The course of the disease was 5 to 45 days, with an average course of (12.00±2.29) days.All the subjects were examined by color fundus photography, fluorescein angiography (FFA), indocyanine green angiography (ICGA), multicolor imaging, spectral-domain optical coherence tomography (SD-OCT). The image features of each patient were compared and analyzed.The diagnostic accordance rate for leakage point and serous retinal neuroepithelial detachment of multicolor imaging and color fundus photography was calculated according to FFA/ICGA and OCT.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2019-K037).Results:The serous retinal detachment region showed green light reflection area with clear boundary in 33 eyes (97.06%) in the standard as well as blue and green enhanced multicolor image, with not clear boundary in 1 eye (2.94%). The serous retinal detachment region showed weakly reflective area in 17 eyes (50%) in blue reflectance image, showed weak reflection with clear boundary in 32 eyes (94.11%) in green reflectance image, showed weakly reflection with clear boundary in 33 eyes (97.06%) in infrared reflectance image.The fluorescein leakage point in FFA image was found micro retinal pigment epithelium detachment (PED) in 19 eyes (55.88%), rough light band of retinal pigment epithelium (RPE) in 12 eyes (35.29%), and large PED in 3 eyes (8.82%) in SD-OCT image.The RPE leakage showed red mottled changes in the area of neuroepithelial detachment in 29 eyes (85.29%) in the standard as well as blue and green enhanced multicolor images, presented strong reflection spots in blue reflectance images in 2 eyes (5.88%), showed strong reflective spots in green reflectance in 5 eyes (14.70%), showed strong reflection spot in the weakly reflective area in 33 eyes (97.06%) in infrared reflectance images.Taking FFA/ICGA and OCT as the gold standard, the diagnostic accordance rate of standard multicolor, blue and green enhanced multicolor and infrared reflectance images for serous retinal neuroepithelial detachment and leakage points was higher than that of color fundus photography, and the differences were statistically significant (all at P<0.05). Conclusions:Standard multicolor, blue and green enhanced multicolor and infrared reflectance images can reflect the leakage point and retinal neuroepithelial detachment of acute CSC.Green reflectance image can show serous retinal neuroepithelial detachment of acute CSC.Multicolor imaging can be used as the auxiliary diagnosis method of acute CSC.

Objective:To explore the application of multispectral fundus imaging (MSI) in central serous chorioretinopathy (CSC).Methods:A diagnostic test study was conducted.Eighty-five eyes from 69 patients with macular diseases were enrolled in Renmin Hospital of Wuhan University from September 2017 to May 2018.There were 62 males (77 eyes) and 7 females (8 eyes) among the 69 patients with an average age of (48.0±11.2) years.The patients were divided into CSC group (45 cases, 61 eyes) and non-CSC group (24 cases, 24 eyes) according to whether suffering from CSC or not.Color fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography, spectral domain-optical coherence tomography and MSI were performed in the two groups and the images were collected.With FFA as the gold standard, the sensitivity, specificity, false positive rate, false negative rate, positive predictive value and negative predictive value of MSI in the diagnosis of CSC were calculated.Kappa consistency test was used to evaluate the consistency of MSI and FFA in diagnosing CSC, and to evaluate the diagnostic value of MSI in CSC.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2019-K037). Written informed consent was obtained from each subject prior to any medical examination.Results:The sensitivity, specicity, false positive rate, false negative rate, positive predictive value and negative predictive value of MSI for identifying CSC were 88.5%, 91.7%, 8.3%, 11.5%, 96.4% and 75.9%, respectively.The Kappa coefficient of agreement was 0.754.There was no significant difference in the identification of CSC between MSI and FFA ( χ2=1.780, P=0.180). Hyper-reflective signals corresponding to the leakage points were better detected with MSI images at 620-850 nm wavelength.The clear boundary of serous neuroepithelial detachment area was better detected with MSI images at 590-810 nm wavelength.The retinal pigment epithelium damage was better detected with MSI images at 660-850 nm wavelength. Conclusions:There is a good consistency between MSI and FFA.MSI can be an effective noninvasive inspection method for CSC.

Objective To observe the imaging features of cystoid macular edema (CME) in multicolor imaging (MC),and to evaluate the value of MC in the diagnosis of CME.Methods Descriptive case series study.From August 2017 to June 2018,42 eyes of 37 patients with CME diagnosed in the people's Hospital of Wuhan University were included in the study.Among them,there were 24 males and 13 females,with an average age of 48.51 ± 10.29 years.There were 14 eyes with diabetic retinopathy,14 eyes with central retinal vein occlusion,8 eyes with branch retinal vein occlusion,4 eyes with uveitis,and 2 eyes with Eales disease.The macular color fundus photography (CFP) was performed with Visucam 200 non-mydriatic fundus camera of Zeiss company in Germany.MC,frequnce domainoptical OCT (SD-OCT) and FFA were examined by Spectralis HRA2 + OCT of Heidelberg company in Germany.According to the MC standard method,five images,including 488 nm blue reflection (BR),515 nm green reflection (GR),820 nm infrared reflection (IR) imaging and standard MC and blue-green enhancement (BG),were obtained at the same time.Compared with SD-OCT,CFP and MC images were scored.Friedman M test and Wilcoxon signed rank test were used for statistical analysis.Results The standard MC and BG images showed blue-green uplift area or petal-shaped appearance,surrounded by green reflection areas with clear boundaries.BR image can be seen in the low reflexes area.On the GR image,there were patches or cystic low reflection areas,surrounded by a slightly high reflection.On the IR image,patches or cystoid high reflexes can be seen,surrounded by low reflection dark areas with clear boundaries.The average scores of CFP,standard MC,GB,IR,GR and BR were 1.20± 0.94,3.05± 0.99,2.90± 1.04,2.55± 1.27,2.00± 0.94,0.51 ± 0.85 respectively,and the differences were statistically significant (χ2=151.61,P=0.000).The score of CFP were significantly lower than that of standard MC (Z=-5.421),BG (Z=-5.354),IR (Z=-4.714),GR (Z=-4.438) and higher than that of BR (Z=-3.435).The differences were statistically significant (P=0.000,0.000,0.000,0.000,0.001).Conclusions The quality of MC imaging is better than that of CFP.Combined with SD-OCT,it can be used as an assistant method to diagnose CME.
