ABSTRACT
Objective: To examine the overall status of the Jiangsu Province Coronary Artery Bypass Grafting Registry database. Methods: The patients date of Jiangsu Province Coronary Artery Bypass Grafting Registry database from October 2017 to December 2019 was collected retrospectively.Risk factors, history, cardiac function (New York Heart Association class), extent of coronary artery lesion, European system for cardiac operative risk evaluation â ¡ (EuroSCORE â ¡), cardiopulmonary bypss, arterial grafts, the numbers and flow of grafts and postoperative major adverse cardiac and cerebrovascular event(MACCE) information were analyzed. The clinical data of patients underwent on-pump CABG(ONCABG) or off-pump CABG (OPCAB) were compared by t test or χ(2) test. Results: Up till December 2019, the database enrolled 7 138 patients, in which 4 661 patients receiving primary isolated CABG. There were 3 486 males and 1 175 females with the age of (64.6±8.1) years (range:31 to 87 years). There were coronary left main disease in 960 patients, triple vessel disease in 3 934 patients, both left main and triple vessel disease in 837 patients, ejection fraction>50% in 3 841 patients, cardiac function class â ¢ to â £ in 1 664 patients. EuroSCORE â ¡ was (2.3±0.7)% (range: 0.5% to 35.8%). There were 2 731 patients (58.59%) underwent ONCABG and 1 930 patients (41.41%) underwent OPCAB. There were 4 144 patients (88.91%) for whom the left internal thoracic artery was harvested. Seven centers (2 centers routinely) used left radial artery, 5 centers (3 centers routinely) used the transit time flow meter. The graft was 3.4±0.7 (range:1 to 7), the aortic crossclamp time was (65.0±20.4) minutes (range: 21 to 196 minutes), the cardiopulmonary bypass time was (90.0±24.2) minutes (range: 33 to 227 minutes). In-hospital death ocurred in 84 patients(1.80%), while re-operation in 93 patients (2.00%), myocardial infarction in 71 patients (1.52%), cerebral infarction in 33 patients (0.71%) and dialysis in 56 patients (1.20%). There were 2 936 patients prescribed with secondary prevention drugs(62.99%).Comparing with OPCAB group, ONCABG group had younger age, more female, more diabetes mellitus, more history of myocardial infarction and percutaneous transluminal coronary angioplasty, poorer cardiac function and coronary lesions, higher EuroSCORE â ¡, preoperatively (all P<0.05), and was associated with higher MACCE (135/2 731 vs. 71/1 930, χ(2)=4.280, P=0.039), and of more grafts, transfusion and intra-aortic balloon counterpulsation application (all P<0.05). Conclusions: Jiangsu Province Coronary Artery Bypass Grafting Registry database is generally in good operation, and some parameters still need to be improved. Comparing with OPCAB group, ONCABG has more severe preoperative general conditions, while the outcomes is acceptable.

Objective: To summarize the clinical and fundus imaging features of purified protein derivative and T-spot positive tubercular serpiginous-like choroiditis (PTP-SLC) patients. Methods: This retrospective study consecutively enrolled 13 PTP-SLC patients (21 eyes) in Beijing Tongren Hospital from November 2015 to November 2017. There were 8 males and 5 females with an average age of (45.2±12.1) years. Medical history and results of systemic and ophthalmological examinations, such us fundus autofluorescence photography, optical coherence tomography (OCT), fluorescein fundus angiography (FFA) and indocyanine green angiography, were evaluated. Results: Eight patients had binocular disease with an average interval time of (8.4±7.9) years. The average visual acuity of all patients was 0.3, and 4 patients had a clear history of exposure to tuberculosis. The active lesions in the PTP-SLC patients were homogeneous and creamish-yellow with unclear boundaries. Fundus autofluorescence showed an ill-defined, diffuse hyperautofluorescent zone. OCT showed punctate hyperreflexes between the choroidal stroma, destruction of the outer retinal structure with intraretinal edema and discrete vitreal hyper-reflective spots. FFA showed hypofluorescence in the active lesion at early stage and diffuse hyperfluorescence with leakage. Indocyanine green angiography showed persistent hypofluorescence. Conclusions: PTP-SLC fundus lesions are mainly manifested as homogeneous creamish-yellow lesions with unclear boundaries and high in autofluorescence. The involvement of the choroid and the outer layer of the retina can be observed on OCT. FFA can find more retinal vascular inflammatory changes. It is difficult to distinguish PTP-SLC from serpiginous choroiditis simply based on clinical and epidemiological characteristics. The pathogenic examination of tuberculosis is still the key to differential diagnosis (Chin J Ophthalmol, 2020, 56: 914-919).

118 specimens of rectal cancer were studied pathologically. 40 cases were treated by both preoperative radiotherapy and intracavitary hyperthermia (group 1), 38 treated by preoperative radiotherapy alone (group 2) and 40 by operation alone (group 3). The tumor disappearance rates by gross observation were 57.5% and 5.3% in groups 1 and 2 (P less than 0.001). The moderate to severe damage of cancer cells (X2-X4) was observed in 90% of cases in group 1 and 31.6% in group 2 (P less than 0.05). In the former, the cancer cell disappearance was observed in 8 cases, while in the latter, only 1 case. The cell degenerations by 30 Gy plus hyperthermia were similar to those by 40 Gy plus hyperthermia, but both were more marked than by 30 Gy alone or 40 Gy alone (P less than 0.05). The lymphocyte, plasma cell infiltration and hyperplasia of fibrous tissue around the tumor in group 1 were more marked than those in groups 2 and 3 (P less than 0.05). The thrombosis around the tumor was more in group 1 than in group 2 (P less than 0.01). Every histological type of the tumor was sensitive to radiotherapy combined with hyperthermia. The lymph node metastatic rates were 35% in group 1 and 31.6% in group 2, both being lower than that in group 3 (52.5%). Immune function of the lymph nodes and the damage of the normal tissues around the tumor are observed. It has been clinically confirmed that neither resection rate is influenced nor postoperative complications are increased by preoperative radiotherapy combined with hyperthermia.

OBJECTIVE: The aim of this study was to investigate whether local application of rapamycin reduced neointimal formation in a rabbit model of venous disease. METHODS: Each rabbit (n = 30; 2.5-3.5 kg) received a treated and a control graft. For the treated graft, 0.3 rapamycin mg was applied locally in Pluronic gel. The control graft received only the Pluronic gel. Grafts were harvested at 28 days for morphometric, immunohistochemical, and flow cytometry analysis. RESULTS: In the control group, the intimal thickness was 63.72 ± 14.0 µm; in treated group, it was 77.76 ± 14.9 µm (P < .05). Immunohistochemically, proliferation cell nuclear antigen-positive cells were present in the control group and in the treatment group but not in normal external jugular veins. The control group showed much stronger expression than the treatment group (P < .05). Flow cytometry showed, among the control group, decreased G(0)G(1)-stage cells and increased S/G(2)M-stage cells. Among the treatment group, S/G(2)M stage cells were decreased compared with the control. The progression indexes of the control and treatment groups were 29.3 ± 7.15 and 20.1 ± 9.48, respectively, a remarkable decrease (P < .05). Proliferating cells in the control group were apparently inhibited by rapamycin. The treatment group showed positive staining for P27(kip1), but neither the control group nor the normal external jugular veins showed positive results (P < .05). The degree of reduction in intimal thickness and inhibition of proliferating cells in the treatment group correlated with the expression of P27(kip1). CONCLUSIONS: We observed that perivascular application of rapamycin inhibited neointimal hyperplasia of vein grafts in a rabbit model, an effect that appeared to result from increased P27(kip1) expression.

PURPOSE: To determine the prevalence of tilted optic discs and their associations with ocular and general parameters. METHODS: The Beijing Eye Study included 4439 subjects out of 5324 subjects invited to participate (response rate 83.4%) with an age of 40+ years. The present investigation consisted of 4324 (97.4%) subjects for whom readable fundus photographs of at least one eye were available. The main outcome parameter was the presence of tilted optic discs defined as small discs with an oblique orientation and oval disc shape without signs of pathology in eyes without high myopia (defined as >-8 D). RESULTS: Tilted optic discs were detected in 31 eyes (0.36; 95% confidence interval: 0.23, 0.49%) of 23 patients (16 women). Tilted discs were associated with myopia (-6.59+/-0.68 D vs -0.60+/-0.02 D, P<0.001), astigmatism (1.55+/-0.24 D vs 0.59+/-0.01 D, P<0.001), lower best corrected visual acuity (P<0.001), visual field defects (P<0.001), and small optic disc area (P<0.001). CONCLUSIONS: Tilted optic discs are present in about four out of 1000 eyes of adult Chinese in Northern China. They are associated with medium myopia, astigmatism, decreased visual acuity, and visual field defects.

Long-term results of 122 patients with advanced rectal cancer who were randomly treated with three different methods from July 1984 to July 1986. Of 122 patients, 44 were treated with endocavitary 915 MHz microwave applicators combined with 10 MeV X-ray or 60CO followed by surgery (group A), 38 with preoperative radiation (group B) and 40 with surgery (group C) as a control group. The temperature on the surface of the applicator touching the middle of the caudad to cephaladic extent of disease was 45-50 degrees C for 45 min twice a week for 6-8 sessions. Radiation dose was 30 Gy or 40 Gy/4 weeks. Of cases with stages 0 and A, 45.5% (20/44) were in group A, 23.7% (9/38) in group B and 12.5% (5/40) in group C (chi 2 test p < 0.05 and p < 0.01, respectively). Five-year survival rate was 66.7% (24/36) in group A, 50% (14/28) in group B and 40.5% (15/37) in group C. Percentage of survival at 5 years was 73.7% (14/19) for 40 Gy plus heat, 57.1% (8/14) for 40 Gy alone, 58.8% (10/17) for 30 Gy plus heat, and 42.9% (6/14) for 30 Gy alone. Data suggest a survival advantage for patients treated with preoperative radiation combined with endocavitary hyperthermia.
