Objective To investigate the clinical features and surgical management of giant coronary artery aneurysm due to mucocutaneous lymph node syndrome(Kawasaki disease).Methods From May 2006 to Oct.2007,5 patients with giant coronary artery aneurysm were undergone surgical correction.The aneurysm mainly appeared in the left bole of coronary artery and the right coronary artery.The ST segment of electrocardiogram changed in 5 cases,cardiac ejection fraction reduced observably in 4 cases,and 1 case suffered from cardiac dysfunction.Coronary angiography showed that the right coronary artery was entirely occluded and ventricular wall motion was depressed in one case.During operation,4 cases were undergone thrombus clearing,endoarterectomy and replasty of coronary artery(with additional procedure of stent placement in one case),one case was undergone coronary artery bypass grafting(CABG) with the aneurysm sequestration.Results The surgical results were satisfactory.No operative death occurred,and all the patients recovered uneventfully and were free of symptoms.In 4 cases,the ST segment of electrocardiogram showed that the blood supply of ischemic myocardium was improved,and the cardiac ejection fraction increased obviously.With 2 to 18 months following-up,all patients were free of symptoms with no death or coronary artery aneurysm recurrence.Conclusions For stage 3 Kawasaki disease complicated with giant coronary artery aneurysm,surgical procedure is necessary.The cardiac function can be improved greatly after comprehensive treatment of thrombus clearing,endoarterectomy,replasty of coronary artery and CABG.

Based on the anatomical study of kidney in mammals of 27 families and 163 species, the authors discovered Anoa depressicornis type kidney, and obtained the evidence of morphological transition between Ox-type kidney and Pig-type kidney. After observing the renal papillary structure of Budorcas taxicolor, the evidence of fact and theoretical bases of the biological view was proved that the general papillae are developed from the multi-papillae kidney. The author advanced a new type of leaf-shaped multipapillae kidney. The authors suggest to classify the mammalian kidneys principally into 2 groups, i. e, simple and composite kidney, and subdivide them into 4 types, i. e, multipapillae and concentrated papillae for simple kidney and leaf-shaped multipapillae and ball-shaped mono-papillae for composite kidney. In contrast to the previous classification, the 2-group 4-type classification recommended here with its solid anatomical foundation is conformable with the viewpoint of biology, and is more practical and integrated.

Objective To observe the effect of fleabane injection on serum level of D-dimer, fibrinogen and hypersensitive C-reactive protein in patients with IgA nephropathy and to explore the mechanism of fleabane injection for treating IgA nephropathy. Methods 29 patients with IgA nephropathy were given fleabane injection together with routine treatment. Another group of 28 patients with IgA nephropathy were only treated with routine treatment as con-trol. Determinations of 24 hours urine protein output(24HPQ), serum level of D-dimer(D-D), Fibrinogen(Fib) and hypersensitive C-reactive protein (hsCRP) were carried out pre- and post-study. Results Significant decrease in 24HPQ , serum level of D-D, Fib and hsCRP were observed in both treatment group and control group(P <0. 01 ～0. 05), but more significant in treatment group as compared with control group ( P < 0. 05). Conclusion Flea-bane Injection plus routine treatment could significantly decrease 24HPQ in patients with IgA nephropathy, and this maybe contribute to regulation of D-D, Fib and hsCRP by fleabane injection.

Objective To explore the effect of 1a,25(OH)2 D3 on circadian clock gene expressions in cardiac myocytes.Methods Cultured cardiac myocytes isolated from 7 -day -old Sprague -Dawley(SD)rats were identified by immunofluorescence.The medium including 1a,25 (OH)2 D3 (final concentrations were 0 nmol/L,1 nmol/L, 10 nmol/L,50 nmol/L and 100 nmol/L)were added to primary myocardial cells to culture for 2 h and then total RNA was extracted.Real -time polymerase chain reaction (RT -PCR)was applied to analyze myocardial cells circadian clock gene (Bmal1,Per2,Rev -erba)transcript levels to determine optimum concentration of 1a,25(OH)2 D3 .Then, the primary myocardial cells cultured for 72 h were divided into 3 groups:the control group was of serum -free culture medium;serum shock group was of DMEMcontaining 50%volume fraction of horse serum cultured 2 h;1a,25(OH)2 D3 treatment group receiving 1a,25 (OH)2 D3 at optimal concentration cultured 2 h.The cells were collected at 7 time points (0 h,4 h,8 h,12 h,16 h,20 h,24 h)and then total RNA was extracted.RT -PCR was applied to analyze circa-dian clock gene (Bmal1,Per2,Rev -erba)transcript levels in the myocardial cells.Results In the presence of 50 nmol/L 1 a,25(OH)2 D3 ,the Bmal1 mRNA expression showed the highest level,but the Per2 and Rev -erba mRNA expression levels were minimum.Compared with the control group,both 1a,25 (OH)2 D3 treatment group and serum shock group caused day -cycle rhythmic oscillation in circadian clock genes(Bmal1,Per2,Rev -erba)in the cardiac myocytes.And the expressions pattern of Bmal1 and Per2 genes were in the opposite phase.While Bmal1 gene expres-sion appeared at peak at 12 h,Per2 gene expression appeared in a trough.Expression of Rev -erba gene trend began to rise at 8 h,and the highest expression level appeared at 12 -16 h.Conclusions 1a,25(OH)2 D3 can affect Bmal1, Per2 and Rev -erba mRNA expressions of circadian clock genes in the cardiac myocytes.

Objective To study the curative effect and the prognostic factors of endoscopic traumatic optic neuropathy (TON). Methods The clinical data of 53 patients with TON from 2010 to 2015 years was retrospectively analyzed. Divided the patients into the surgery group and the non-surgery group, according to whether or not accept the treatment of endoscopic optic decompression. And evaluating the potential prognostic factors in chi-square test, group t-test and multiple regression analysis. Results In 53 patients (55 eyes ), 31 eyes have no visual acuity before treated: 8 eyes’ visual acuity was improved in 16 eyes (8/16) that accepted operation; 3 eyes’ visual acuity was improved in 15 eyes (3/15) that with non-operation;24 eyes have visual acuity before treated:11 eyes’ visual acuity was improved in 14 eyes (11/14) that accepted operation;3 eyes’ visual acuity was improved in 10 eyes (3/10) that with non-operation;19 eyes’ visual acuity was improved in 30 eyes (19/30) that accepted operation, the total effective rate was 63.3%, and there was no complications happened in the patients who accepted operation. The age, eye-side, sex, visual acuity, optic canal fracture , orbit fracture , all these factors have no correlation to the prognosis (P>0.05), but the interval time between injury and operation (less than 3 days) and the way of the treatment are benefit to improve vision (P<0.05). Conclusions The endoscopic optic decompression is an effective treatment in TON, and it’s better to improve vision in 3-day after TON.

Objective To investigate the effect of vitamin D (VD) on gastric cancer and its underlying mechanisms by detecting serum VD levels in gastric cancer patients and the expression of vitamin D receptor (VDR) in gastric tumor.Methods Serum VD levels was detected by enzyme linked immunosorbent assay,VRD expression of tumor tissue and normal mucosa were detected by immunohistochemistry.At the same time,relationships of VDR expression and the prognosis of the patients were analyzed.Results The serum levels of VD of gastric cancer patients were lower than that of healthy people (P＜0.05),and they were negatively related to the degree of cell differentiation significantly (P＜0.001).VDR expression in gastric tumor tissue significantly decreased compared to that of the normal mucosa (P＜0.05).A significant correlation was found between the VDR expression and the differentiation grade of the carcinoma,with well differentiated carcinoma having the highest level of VDR expression (P＜0.05).For patients with gastric cancer,those with positive VDR expression had significant longer progression-free survival (PFS) and overall survival (OS) than the patients with negative VDR expression (P＜0.05).Conclusions VD may be a protecting factor of gastric cancer.VDR can be regarded as a marker of differentiation of gastric cancer and served as an effective prognostic factor in patients with postoperative gastric cancer.

OBJECTIVE To investigate the effect of subcutaneousimmunotherapy(SCIT) on levels of the serum human beta defensin-2 in children with allergic rhinitis. METHODS 30 cases of children with allergic rhinitis who were treated by SIT were selected as the treatment group, 20 cases of healthy children as the control group. Serum HBD-2 concentration of the control group was tested. Serum HBD-2 concentration of the treatment group was tested at three different time points: before SCIT, half a year after SCIT and one year after SCIT. And total nasal symptom scores(TNSS) and medication scores were recorded at each time point. RESULTS The serum HBD-2 concentration of the control group, that of the treatment group before SIT, half a year after SIT and one year after SIT were 4.62[4.08; 4.87], 3.74[3.37; 4.61], 4.62[4.13; 5.54], 4.79[4.45;6.19]ng/ml. The HBD-2 concentration gradually increased after SCIT. The TNSS of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 7.43±2.15, 4.17±2.16, 4.20±1.92, The medication scores of the treatment group before SCIT, half a year after SCIT and one year after SCIT were 1.25[0.75; 1.38], 0.25[0; 0.75, 0.25[0; 0.75].There was no correlation (all P>0.05) between the serum HBD-2 concentration and TNSS or medication scores of the treatment group. CONCLUSION The serum levels of HBD-2 in patients with allergic rhinitis were lower than those in normal persons. The specific immunotherapy raised the serum HBD-2 levels of allergic rhinitis patients.

Objective:To compare the clinical efficacy and safety of continuous dosing or alternate-day dosing of apatinib combined with SOX regimen as first-line treatment for patients with advanced gastric cancer.Methods:A total of 52 patients with human epidermal growth factor receptor 2 (HER2) negative and inoperable locally advanced or advanced gastric cancer who were pathologically diagnosed from January 2018 to January 2021 in the Second Affiliated Hospital of Shandong First Medical University were collected. The patients were divided into continuous dosing group and alternate-day dosing group by random number table method. The continuous dosing group received apatinib (250 mg, once a day) combined with SOX regimen (S-1+oxaliplatin); the alternate-day dosing group received apatinib (250 mg, once every other day) combined with SOX regimen. Twenty-one days were a cycle, and the efficacy was evaluated after 2 cycles. After 4-6 cycles, patients with stable disease received apatinib and S-1 for maintenance therapy. The therapeutic effects and adverse reactions of the two groups were compared.Results:The curative effect could be evaluated in 51 patients, including 26 in the continuous dosing group and 25 in the alternate-day dosing group. The disease control rates in the continuous dosing group and the alternate-day dosing group were 84.6% (22/26) and 76.0% (19/25) ( χ2 = 0.60, P = 0.499), and the median progression-free survival time was 7.50 months (95% CI 6.17-8.83 months) and 8.30 months (95% CI 6.99-9.61 months) ( χ2 = 0.71, P = 0.401), and the median overall survival time was 15.50 months (95% CI 11.30-19.69 months) and 15.60 months (95% CI 13.63-17.57 months) ( χ2 = 1.82, P = 0.177). The main adverse reactions in the two groups were leukopenia, thrombocytopenia, hypertension, nausea, vomiting, fatigue, hand-foot syndrome, proteinuria, liver and kidney damage. The incidence rates of ≥grade 3 adverse reactions in the continuous dosing group and the alternate-day dosing group were 42.3% (11/26) and 12.0% (3/25), and the difference was statistically significant ( χ2 = 4.46, P = 0.035). Conclusions:The efficacy of continuous dosing or alternate-day dosing of apatinib combined with SOX regimen as first-line treatment for advanced gastric cancer is similar, but the incidence of ≥grade 3 adverse reactions in alternate-day dosing group is lower, which improves the compliance and tolerance of patients.

Objective:To investigate the relationship between serum C3 and progression of renal function in IgA nephropathy.Methods:A single-center retrospective cohort study was conducted in patients with IgA nephropathy confirmed by renal biopsy who were admitted to the Second People's Hospital of Shenzhen from January 2011 to June 2020 and the patients were followed up until January 2021. Patients with secondary IgA nephropathy, baseline estimated glomerular filtration rate (eGFR)<30 ml·min -1·(1.73 m 2) -1, lack of baseline serum C3 or creatinine, and follow-up time<6 months were excluded. The clinical data, laboratory examination and renal pathology were collected. The threshold effect analysis was used to obtain the cut-off point, and inflection point and 95% confidence interval were obtained using bootstrapping resampling technique. According to the cut-off point, the patients were divided into serum C3<0.97 g/L group and C3≥0.97 g/L group. The baseline data between the two groups were compared. Cox regression model was used to analyze the correlation between serum C3 level and renal function progression. Results:A total of 414 patients were enrolled in this study, with 145 males (35.0%), and age of (35.15±9.18) years old. The baseline eGFR was 77.80(46.67, 106.10) ml·min -1·(1.73 m 2) -1, and the serum C3 was (1.04 ± 0.19) g/L. There were 153 patients with serum C3<0.97 g/L and 261 patients with serum C3≥0.97 g/L. Compared to patients with serum C3≥0.97 g/L, those patients with serum C3<0.97 g/L were younger and had higher proportion of females, higher levels of hemoglobin and eGFR, and lower levels of mean arterial pressure, total cholesterol, triglyceride, serum uric acid, serum creatinine, 24 h urinary protein, IgA and C4 (all P<0.05). The relationship between serum C3 and progression of renal function was found to be U-shaped by smooth curve fitting. After adjustment for confounding factors such as age, sex, mean arterial pressure, serum uric acid, 24 h urinary protein, and renal pathology (MESTC), the results of the threshold effect and multivariate Cox regression showed, for patients with C3<0.97 g/L, the risk of renal function progression decreased by 40% for every 0.1 g/L increase of C3 ( HR=0.60, 95% CI 0.39-0.94, P=0.024), but for patients with C3≥0.97 g/L, every 0.1 g/L increase in serum C3 increased the risk of renal function progression by 27%( HR=1.27, 95% CI 1.03-1.57, P=0.027). The inflection point was 0.97(95% CI 0.92-1.01) g/L. Conclusions:Serum C3 is nonlinear correlated with the progression of renal function in patients with IgA nephropathy. Serum C3 level maintaining at 0.92-1.01 g/L is associated with better renal prognosis.
