AIM: To explore the clinical value of 25 - gauge vitrectomy in the treatment of traumatized eyes with non-light perception.?METHODS:Forty-six patients (46 eyes) who diagnosed as traumatized eyes with non-light perception treated with 25-gauge vitrectomy, which collected in our hospital from July 1, 2013 to June 1, 2017. Their sex, age, residence area, traumatic nature, causes of injury, duration from the injury to intervention, location and size of the wound, visual acuity and prognosis was retrospectively studied and analyzed statistically in this study.?RESULTS: In the 46 patients, 38 were males, 8 were females (M :F= 4. 75:1). The age of the patients was between 7 and 77 years ( mean 37. 96 ± 18. 99 years). Among them, there were 26 case ( 57％) in the young group (<45 years ) , 14 case ( 30％) in the middle age group ( 45-60 years ) , 6 cases ( 13％) in the older age group (>60 years ) . The cause of injury included blunt trauma ( 18 cases, 39％) , sharp instrument injury ( 8 cases, 17％) , plant injury ( 6 cases, 13％) , explosion injury (6 cases, 13％), impact injury (4 cases, 9％), limb impact injury ( 2 cases, 4％) , traffic accident injury ( 2 cases, 4％) . There were 33 cases ( 72％) with ocular rupture, 12 cases (26％) with perforating injury of eyeball and 1 case ( 2％) with ocular contusion. There were 44 cases (96％) with vitreous hemorrhage, 30 cases (65％) with retinal detachment, 18 cases ( 39％) with intraocular foreign body (IOFB), 22 cases (48％) with cilio-choroidal detachment, 18 cases (39％) with endophthalmitis and 12 cases (26％) with retinal hemorrhage. The postoperative best-corrected visual acuity improved to light perception or better than light perception in 30 cases ( 65％) , and 16 cases (35％) still had no light perception.? CONCLUSION: The patients who had no light perception after ocular trauma were almost young and middle- aged people in rural areas. The factors that affected the visual acuity of the postoperative included the type of injury, the location and size of the wound, the retinal detachment, the cilio-choroidal detachment, the duration from the injury to intervention, the endophthalmitis and whether the merger of intraocular foreign body or not. The 25-gauge vitrectomy could make most of the visual acuity from no light perception to light perception or over the light perception, which had a high clinical value in curing traumatized eyes with no light perception.

BACKGROUNDThis study was to examine the expression of total vascular endothelial growth factor (VEGF) and the anti-angiogenic VEGF 165 b isoform in the vitreous body of retinopathy of prematurity (ROP) patients, and to further study the role of the VEGF splicing in the development of ROP.

METHODSThis was a prospective clinical laboratory investigation study. All patients enrolled received standard ophthalmic examination with stage 4 ROP that required vitrectomy to collect the vitreous samples. The control samples were from congenital cataract patients. The expression of total VEGF and the anti-angiogenic VEGF 165 b were measured by enzyme-linked immunosorbent assay. Results were analyzed statistically using nonparametric tests.

RESULTSThe total VEGF level was markedly elevated in ROP samples while VEGF 165 b was markedly decreased compared to control group. The relative protein expression level of VEGF 165 b isoform was significantly decreased in ROP patients which were correlated with the ischemia-induced neovascularization.

CONCLUSIONSThere was a switch of VEGF splicing from anti-angiogenic to pro-angiogenic family in ROP patients. A specific inhibitor that more selectively targets VEGF 165 and controls the VEGF splicing between pro- and anti-angiogenic families might be a more effective therapy for ROP.

Objective To explore distribution characteristics and risk factors of cerebral microbleeds (CMBs),and the correlation between CMBs and white matter lesions (WML) in patients with ischemic cerebrovascular disease(ICVD).Methods 180 patients with ICVD in neurology department of Hebei General Hospital from February 2015 to January 2017 were recruited.Those patients were underwent brain magnetic resonance imaging (MRI),and magnetic susceptibility weighted imaging (SWI).Recorded the baseline data and risk factors of high blood pressure,diabetes,hyperlipidemia,and high homocysteine were recorded.Patients with CMBs were counted and graded to understand the characteristics of CMBs distribution.Logisitic regression analysis was used to analyze the influencing factors.ICVD patients were divided into CMBs group and non CMBs group.CMBs group was further divided into 4 groups according to the severity,which was divided into level 1-3.The correlation between CMBs influencing factors and classification was further studied.Then patients with ICVD were divided into WML group and non WML group.WML group scored each region with age-related white matter changes rating scale (ARWMCrs).The correlation between WML and CMBs classification was further studied.Results (1) The overall prevalence of CMBs in patients with ICVD was 61.7％ (111/180).The most common location of CMBs in patients with ICVD was the cortical and subcortical regions (80/111,72.1％),followed by the basal ganglia and thalamus regions (61/111,55.0％),and the infratentorial regions(38/111,34.2％).The difference between them were significant (x2 =32.061,P=0.000).In cortical and subcortical regions of CMBs,temporal lobe was the most common (61.3％).(2) Age(B=0.046,Or=1.047,95％CI =1.017～ 1.077,P=0.002) and the high homocysteine (B =1.458,Or=4.299,95％ CI =2.114 ～ 8.744,P＜0.001) were the risk factors for CMBs.(3) Four classification of CMBs was positively correlated with and WML total score (r=0.393,P=0.393).Conclusion The temporal lobe was the most common region for CMBs in patients with ICVD.Age and high homocysteine were risk factors for CMBs.With the increase of WML total score,severity of CMBs was also increased.

OBJECTIVETo investigate the effect of laparoscopic Roux-en-Y gastric bypass on the short-term immune function of type 2 diabetic patients and to explore the correlation between the immune regulatory effect and blood glucose control.

METHODSClinical data of 28 patients with type 2 diabetes mellitus who underwent laparoscopic Roux-en-Y gastric bypass surgery in our hospital during January 2014 to January 2015 were retrospectively collected. Fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), immunoglobulin (IgG, IgA, IgM), T lymphocytes CD3(+), killer T cells CD3(+)CD8(+), helper T cells CD3(+)CD4(+), natural killer(NK) cell subsets CD16(+),CD56(+) and B cell subsets CD19(+),CD45(+) levels were detected and compared between before and after surgery. Correlation of immunoglobulin and immune cell subsets with the level of FBG and HbA1c were examined.

RESULTSAfter operation, FBG and HbA1c decreased significantly from (5.78±1.15) mmol/L to (14.21±1.89) mmol/L, and (9.96±0.97)% to (6.87±0.69)%, respectively (all P<0.05), and immunoglobulin (IgG, IgA, IgM) increased significantly [IgG: from(9.41±1.23) g/L to (12.74±1.61) g/L, IgM: from (1.71±0.22) g/L to (2.43±0.39) g/L, IgA: from (1.25±0.26) g/L to (1.97±0.23) g/L, all P<0.05]. Besides, T lymphocytes CD3(+), killer T cells CD3(+)CD8(+) and B cell subsets CD19(+)CD45(+) elevated significantly as well [T lymphocytes CD3(+): from (55.3±3.8)% to (67.6±4.6)%, killer T cells CD3(+)CD8(+): from (15.6±5.3)% to (28.7±4.2)%, B cell subsets CD19(+)CD45(+): from (8.4±3.7)% to (18.1±4.1)%, respectively, all P <0.05]. There was no significant difference in the expression of helper T cells CD3(+)CD4(+) and natural killer cell subsets CD16(+)CD56(+) between pre-operation and post-operation(all P>0.05). Levels of immunoglobulin (IgG, IgA, IgM), CD4(+)/CD8(+) ratio and B cell subsets were negatively correlated with HbA1c and FBG levels (IgG with FBG: r=-0.865, IgA with FBG: r=-0.887, IgM with FBG: r=-0.902, CD4(+)/CD8(+) with FBG: r=-0.956, CD19(+)CD45(+) with FBG: r=-0.834; IgG with HbA1C: r=-0.859, IgA with HbA1C: r=-0.957, IgM with HbA1C: r=-0.843, CD4(+)/CD8(+) with HbA1C: r=-0.912, CD19(+)CD45(+) and HbA1C: r=-0.885, all P<0.05), but the proportion of NK cells was not significantly correlated with HbA1c and FBG (P>0.05).

CONCLUSIONSLaparoscopic Roux-en-Y gastric bypass has good effect on the immune function of patients with type 2 diabetes mellitus. Improvement of immune function is correlated with the control of FBG and HbA1c.

Objective:To investigate the application value of dual-graft living donor liver transplantation of right segment from an adult living donor combined with a left lateral segment from donation after brain death for hepatocellular carcinoma (HCC).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of a male 46-year-old patient with HCC who underwent dual-graft living donor liver transplantation of right segment from an adult living donor combined with a left lateral segment from donation after brain death at the West China Hospital of Sichuan University in October 2019 were collected. He weighed 66 kg and was 171 cm in height. His blood type was A Rh-positive. Graft one was from a female 23-year-old living donor who had a bodyweight of 50 kg, a height of 150 cm, and blood type of A Rh-positive; graft two was from a male 44-year-old brain death donor with the blood type of A Rh-positive. The surgery was performed in three operating rooms, graft one and graft two were obtained simultaneously in two operating rooms, and the recipient′s liver was dissected in the third operating room. When the in vitro splicing of the liver was almost completed, surgeons entirely removed the recipient′s liver and started to transplant the new one. Observation indicators: (1) surgical situations and postoperative recovery of the living donor and the recipient; (2) postoperative pathological examination of the recipient′s liver; (3) follow-up. Follow-up was conducted by outpatient examinations, including monitoring of HCC recurrence, monitoring of new liver function, monitoring and adjustment of immunosuppressive agents, detection of biliary vascular complications, rejection and adverse drug reactions. Regular lifelong follow-up was required for recipients, with the latest follow-up on December 4, 2019. Count data were expressed as absolute numbers or percentages.Results:(1) Surgical situations and postoperative recovery of the living donor and the recipient: operation time, volume of intraoperative blood loss, volume of intraoperative infusion of autologous blood of the living donor were 315 minutes, 200 mL, 200 mL, respectively. The living donor was discharged from hospital on the sixth day after surgery without any complications. The recipient underwent modified piggyback liver transplantation successfully. Graft one was from the right segment free of the middle hepatic vein in the living donor, with a weight of 410 g. Graft two was from the left lateral segment in the donor after brain death, with a weight of 400 g. The graft from donors to recipient weight ratio was 1.2% after splicing. The operation time, duration of anhepatic phase, volume of intraoperative blood loss, volume of intraoperative blood transfusion were 815 minutes, 60 minutes, 1 500 mL, 1 800 mL, respectively. The recipient′s temperature was normal during hospitalization. On the first postoperative day, the level of white blood cell and neutrophilic granulocyte percentage of the recipient reached a peak (17.15×10 9/L and 91.7%, respectively) and then gradually decreased. After anti-infective treatment with piperacillin sodium and sulbactam sodium, both of the two indicators returned to normal on the seventh day after surgery (7.90×10 9/L and 70.9%, respectively), and the antibiotic was discontinued. During the hospitalization, the level of albumin of the recipient fluctuated in 31.0-41.4 g/L, the liver function parameters including total bilirubin, alanine aminotransferase, aspartate aminotransferase, prothrombin time and international normalized ratio gradually returned to normal levels, and the renal function parameters including creatinine and estimated glomerular filtration rate remained within the normal range. On the tenth day after surgery, the recipient was in good condition and discharged from the hospital. (2) Postoperative pathological examination of the recipient′s liver: ① results of the pathological examination showed moderately differentiated HCC with incomplete tumour capsule and no invasion of the liver capsule. The surrounding liver tissues showed hepatitis B-related nodular cirrhosis, and no tumor involvement was detected at the broken end of the hilum. ② The gallbladder presented chronic cholecystitis accompanied by cholesterol deposition, and one abdominal lymph node showed reactive hyperplasia. The immunohistochemical staining showed 10% positive HBsAg and negative HBcAg. (3) Follow-up: the tumor markers of the recipient were tested on November 19, 2019, including α-fetoprotein (2.92 μg/L) and abnormal prothrombin (16 AU/L). Together with the negative result of abdominal colour doppler ultrasound, they collectively indicated no HCC recurrence in the recipient. The liver function parameters including total bilirubin (8.6 μmol/L), alanine aminotransferase (23 IU/L), aspartate aminotransferase (28 IU/L) and albumin (44.0 g/L) of the recipient tested on December 3, 2019, were all in normal levels. Blood concentration of tacrolimus was 4.2 μg/L . The drug dose of mycophenolate mofetil dispersible tablets was adjusted to 250 mg given twice daily, and the drug dose of others was unchanged (tacrolimus 2 mg, once daily; sirolimus 1mg, once daily). No symptoms, signs or examination results indicated biliary vascular complications, rejection or adverse drug reactions. Conclusion:Dual-graft living donor liver transplantation of right segment from an adult living donor combined with a left lateral segment from donation after brain death is safe and effective, which can be used as a suboptimal treatment for patients with HCC beyond Milan criteria.

BACKGROUNDClarifying the risk factors for postoperative complications and taking measures to minimize these complications will improve the outcomes in patients with ulcerative colitis (UC). This study aimed to systemically explore the risk factors for short-term postoperative complications in Chinese UC patients undergoing ileocolorectal surgery.

METHODSForty-nine UC patients undergoing proctocolectomy or ileostomy were retrospectively enrolled. Univariate and multivariate logistic regression analyses were conducted to reveal the risk factors among the clinical, laboratory, and surgical variables as well as preoperative medications.

RESULTSTwenty-two (44.9%) patients who suffered from at least one short-term postoperative event had more severe hypoalbuminemia (P = 0.007) and an increased prevalence of preoperative corticosteroid usage (prednisone more than 20 mg daily or equivalent) for more than 6 weeks (59.1% vs. 25.9%, P = 0.023) compared with patients without short-term postoperative complications. Based on the multivariate logistic regression analysis, the odds ratio (95% confidence interval) values of these two risk factors were 1.756 (0.889-3.470, P = 0.105) and 3.233 (0.916-11.406, P = 0.068), respectively. In 32 severe UC patients, prolonged preoperative hospital stay worsened the short-term postoperative outcomes.

CONCLUSIONSPreoperative corticosteroids usage and hypoalbuminemia worsened the short-term outcomes following ileocolorectal surgery in Chinese UC patients.

The efficacy of tandem high-dose chemotherapy and autologous stem cell rescue (HDCT/ASCR) was investigated in patients with high-risk neuroblastoma. Patients over 1 yr of age who were newly diagnosed with stage 4 neuroblastoma from January 2000 to December 2005 were enrolled in The Korean Society of Pediatric Hematology-Oncology registry. All patients who were assigned to receive HDCT/ASCR at diagnosis were retrospectively analyzed to investigate the efficacy of single or tandem HDCT/ASCR. Seventy and 71 patients were assigned to receive single or tandem HDCT/ASCR at diagnosis. Fifty-seven and 59 patients in the single or tandem HDCT group underwent single or tandem HDCT/ASCR as scheduled. Twenty-four and 38 patients in the single or tandem HDCT group remained event free with a median follow-up of 56 (24-88) months. When the survival rate was analyzed according to intent-to-treat at diagnosis, the probability of the 5-yr event-free survival+/-95% confidence intervals was higher in the tandem HDCT group than in the single HDCT group (51.2+/-12.4% vs. 31.3+/-11.5%, P=0.030). The results of the present study demonstrate that the tandem HDCT/ASCR strategy is significantly better than the single HDCT/ASCR strategy for improved survival in the treatment of high-risk neuroblastoma patients.

Objective:To investigate the safety, efficacy and application indication of intra-operative cell salvage (IOCS) in cesarean section.Methods:A total of 1 265 pregnant women who received IOCS blood transfusion during cesarean section in 11 tertiary A hospitals from August 2016 to January 2019 were collected and divided into <1 500 ml group (796 cases) and ≥1 500 ml group (469 cases) according to the amount of blood loss during cesarean section. The general clinical data, ultrasonic imaging data, perinatal and puerperium indicators were analyzed retrospectively. The risk factors of intraoperative blood loss ≥1 500 mL using IOCS transfusion were analyzed by logistic multivariate regression.Results:(1) A total of 848 001 ml of blood was recovered and a total of 418 649 ml of blood was transfused in 1 265 pregnant women who received IOCS transfusions, which was equivalent to 23 258 U red blood cell suspension, greatly saving medical resources. The intraoperative blood loss in <1 500 ml group and ≥1 500 ml group was 800 ml (300-1 453 ml) and 2 335 ml (1 500-20 000 ml), respectively. No amniotic fluid embolism, severe adverse reactions, shock and death occurred in the two groups. (3) Multivariate regression analysis showed that age ≥35 years ( OR=1.5, 95% CI: 1.1-1.9), prenatal hemoglobin level <110 g/L ( OR=1.7, 95% CI: 1.3-2.2), history of uterine surgery ( OR=1.8, 95% CI: 1.3-2.6), placenta previa ( OR=1.9, 95% CI: 1.1-3.1), placenta accreta ( OR=2.6, 95% CI: 1.8-3.9), blood pool in the placenta ( OR=1.6, 95% CI: 1.1-2.3), abnormal posterior placenta muscle wall ( OR=1.8, 95% CI: 1.2-2.6), placenta projecting to the anterior uterine wall ( OR=3.0, 95% CI: 1.3-7.0) were risk factors for blood loss ≥1 500 ml in obstetric transfusion using IOCS technique, with statistical significance (all P<0.05). Conclusion:IOCS is safe and effective in cesarean section, which could save the medical resources and reduces medical expenses, however, it is necessary to strictly master the application indication.
