    Objective To assess the outcomes of primary arterial switch operation (ASO) in treatment of D-transposition of the great arteries (DTGA) with intact ventricular septum (IVS) in children older than 3 weeks, and explore the significance of helix ventricular myocardial band (HVMB) in the treatment of DTGA/IVS. Methods The clinical data of 54 children with DTGA/IVS aged between 3 weeks and 16 months (late ASO group) and 74 children with DTGA/IVS aged less than 3 weeks (early ASO group) were analysed. In late ASO group, children were subdivided into ventricular septal migration (VSM) group (n=20, ventricular septa were straight or skewed to the left) and ventricular septal normal (VSN) group (n=34, ventricular septa were normal in appearance). The surgical outcomes of ASO were evaluated. Results There was no significant difference in time of extracorporeal circulation, time of aortic clamping, time of ventilator application after operation, time of intensive care after operation, duration of hospitalization and mortality between late ASO group and early ASO group (P>0.05). There was no significant difference in mortality between VSM group and VSN group (10.0% vs 8.8%, P>0.05). Conclusion Primary ASO may be appropriate treatment for children with DTGA/IVS aged between 3 weeks and 16 months, and the normal appearance of ventricular septa plays an important role in the outcomes, which can be well explained by the theory of HVMB.

    Abstract4813)      PDF(pc) (4240KB)(1288)       Save

    Objective To explore the relationship between depth of burn wound and volume of fluid infusion during shock stage. Methods The clinical data of patients with total burn surface area no less than 25% of total body surface area and undergoing fluid infusion by Ruijin resuscitation formula during shock stage were collected. The total burn surface area, full-thickness burn surface area and volumes of fluid infusion in the first and second 24 h after burn were recorded, the ratio of full-thickness burn surface area to burn surface area (full-thickness burn surface area ratio) was calculated, and volumes infused per body weight and burn surface area (VIWB)in the first and second 24 h after burn were obtained. The relationship between full-thickness burn surface area ratio and VIWB was explored, the regression equations were established, and the corrected VIWB in the first and second 24 h after burn were calculated. Results The data of 166 patients were included. Compared with VIWB of patients with superficial burn (n=53), those of patients with fullthickness burn (n=7) increased 37% and 41% in the first and second 24 h after burn, respectively (P<0.05). Fullthickness burn surface area ratio was significantly positively related to VIWB in the first and second 24 h after burn (R2=0.138, P<0.001; R2=0.108, P<0.001). The regression equations were y=0.537x+1.595 and y=0.314x+0.775. Compared with corrected VIWB in the first and second 24 h after burn of patients with superficial burn, those of patients with full-thickness burn and same burn surface area increased 35% and 41%, respectively. With each 20% increase in full-thickness burn surface area ratio, the corrected VIWB in the first and second 24 h after burn increased 0.1 and 0.06, respectively. Conclusion Full-thickness burn surface area ratio is related to volume of fluid infusion during shock stage, and corrected formula is suitable to VIWB of different depth of burn wound.

    Abstract4468)      PDF(pc) (6147KB)(2359)       Save

    Objective To isolate and identify Porphyromonas gingivalis (P. gingivalis) from clinical subjects, and analyse the growth characteristics of P. gingivalis. Methods Subgingival plaque samples were collected from patients with chronic periodontitis and periodontally healthy subjects, and anaerobic culture was performed. P. gingivalis strains were identified by PCR and 16S rDNA sequencing, and detection rate was analysed. Bacteria colonies and growth characteristics of the clinical strains of P. gingivalis were observed, and the biological properties were analysed. Results Six P. gingivalis clinical strains named as L2, L3, L4, L5, L11 and L12 were isolated from 146 subgingival plaque samples collected from 35 subjects. The detection rate of P. gingivalis was 27.4% in subgingival plaque samples of periodontally healthy subjects, 86.7% in periodontally healthy sites of patients with chronic periodontitis, 95.6% in periodontal pockets with probing depth of 4-6 mm, and 96.0% in periodontal pockets with probing depth >6 mm. Strains L2, L5, L11 and L12 formed black colonies on BHI plates after culture for 1 week. Strains L3 and L4 formed grey colonies 1 week after culture for 1 week, and formed black colonies after culture for 10 d. Strains L2, L4, L5 and L12 grew to exponential phase 30 h after inoculation, whereas strains L3 and L11 grew to exponential phase 60 h after inoculation. Conclusion P. gingivalis is one of the dominant pathogenic bacteria in periodontal pockets of patients with chronic periodontitis. The detection rate of P. gingivalis in healthy sites of patients with chronic periodontitis is significantly higher than that of periodontally healthy subjects, and the detection rates of P. gingivalis are higher in deeper periodontal pockets. The growth characteristics of P. gingivalis clinical strains vary from each other, indicating that the biological and pathogenic properties of P. gingivalis may be strain-specific.

    G protein-coupled estrogen receptor 1 (GPER) is a novel receptor, which belongs to the family of G protein-coupled receptors, to many of the rapid biological responses to estrogen. Different from the two classical nuclear estrogen receptors, ERα and ERβ, GPER modulates both rapid non-genomic reaction and genomic transcriptional events of estrogen. In this regard, GPER may be considered as a valuable target toward novel therapeutic strategy for many estrogen-related diseases. The intrinsic appearance of GPER, including structure, subcellular localization, ligands, signal transduction pathway and relationship with diseases is reviewed in this paper.

    Objective To investigate the expression of cyclophilin B (CypB) in colorectal cancer tissues with or without lymph node metastasis, and explore the effects of CypB plasmids knockdown on metastasis and invasion of cancer cells. Methods The expression of CypB in 59 colorectal cancer tissue microarray, including 31 without lymph node metastasis and 28 with lymph node metastasis, were evaluated with immunohistochemistry. Colorectal cancer cell line SW1116 was transfected with shRNA plasmids targeting CypB(SW1116-siCypB) and negative control plasmids(SW1116-NC). CypB knockdown effects were analysed with Western blotting. Wound healing assay and transwell cell invasion assay were performed to observe the effects of CypB knockdown on metastasis and invasion of SW1116 cells. Results The expression of CypB in colorectal cancer tissues with lymph node metastasis was significantly higher than that in colorectal cancer tissues without lymph node metastasis (P<0.01). Compared with SW1116-NC, the expression of CypB of SW1116-siCypB significantly reduced (P<0.01), and the performance of metastasis and invasion significantly decreased (P<0.01). Conclusion CypB plays an important role in lymph node metastasis of colorectal cancer, which makes it a potential target for the prevention and treatment of lymph node metastasis of colorectal cancer.

    Objective To explore the clinical significance of detection of 14 kinds of food allergen-specific IgG. Methods Fourteen kinds of food allergen-specific IgG were detected by ELISA method in 211 patients with allergic diseases, and IgG positive rates of various foods were compared among patients with different sex, age and allergic diseases. Results Positive food allergen-specific IgG was detected in 193 (91.4%) patients. Among 14 kinds of foods, the positive rate of food allergen-specific IgG was the highest for eggs (73.9%), and milk came the second. However, no elevated food allergen-specific IgG was observed for chicken and meat. Milk was the most common sensitizers for 0-12 month-old patients, and egg was the first cause for the other age groups. There were significant differences in the positive rates of food allergen-specific IgG for milk among different age groups (P<0.01). There was no significant difference in the positive rate of food allergen-specific IgG between males and females (P>0.05). The positive rate of food allergen-specific IgG in patients with eczema was the highest (96.4%), and the lowest (83.3%) was found in those with chronic diarrhea, while there was no significant difference among different diseases (P>0.05). The positive rate of food allergen-specific IgG for milk differed significantly among different diseases (P<0.01). Positive food allergen-specific IgG was detected in 12 kinds of food (except for chicken and meat) for patients with allergic purpura. Conclusion Food intolerance is a complex allergy.

    Objective To evaluate the impact of bilateral ovariectomy in post-menopausal women by comparison of climacteric symptoms before and after operation. Methods Post-menopausal women who received hysterectomy with concurrent bilateral ovariectomy on benign uterine indications were recruited. Climacteric symptoms before and after operation were accessed by a questionaire including modified Kupperman Index. Comparison was made after grouping the patients into early menopause group, whose menopausal period was no more than 5 years, and late menopause group, whose menopausal period was more than 5 years. Results Among a total of 95 individuals, 8 had normal, 46 had mild, 34 had moderate, and the other 7 had severe Kupperman Index scores before operation, while 5 had normal, 28 had mild, 48 had moderate, and the other 14 had severe Kupperman Index scores after operation, with more moderate and severe climacteric symptoms after operation than before operation (P<0.05). Women of early menopause group had higher total Kupperman Index scores and symptom scores of sweating, insomnia, depression, fatigue and headache than those of late menopause group before operation (P<0.05). Women of early menopause group had significantly higher Kupperman Index scores after operation than before operation (23.93±7.53 vs 17.63±8.07, P<0.05). However, there was no significant difference in total Kupperman Index scores in women of late menopause group before and after operation. Conclusion Bilateral ovariectomy may affect the climactic symptoms in post-menopausal women, especially in early menopausal period.

    Objective To analyse the relationship between estimated glomerular filtration rate (eGFR) and 99mTc-glomerular filtration rate (99mTc-GFR), and explore the suitable methods for eGFR of Chinese inpatients with chronic kidney disease (CKD). Methods One thousand and thirty-three inpatients with CKD were selected, 99mTc-GFR was measured by 99mTc-diethylenetriaminepentaacetic acid (99mTc-DTPA) dynamic renal imaging, and serum creatinine (SCr) was determined by enzymatic method. Cockcroft-Gault formula, modification of diet in renal disease (MDRD) equation, abbreviated MDRD equation, MDRD equation for Chinese, abbreviated MDRD equation for Chinese and CKD-EPI equation were employed for calculation and body surface area (BSA) was used for correction of eGFR (C-G GFR, 7GFR, aGFR, c-7GFR4, c-aGFR4 and CKD-EPI-GFR, respectively). The relationship between 99mTc-GFR and eGFR was analysed. Results Correlation regression analysis revealed that the correlation coefficients between C-G GFR, 7GFR, aGFR, c-7GFR4, c-aGFR4, CKD-EPI-GFR and 99mTc-GFR were 0.805, 0.797, 0.783, 0.791, 0.777 and 0.800, respectively, and the differences were -2.46, -14.24, -16.53, -20.92, -22.92 and -13.56, respectively. There was approximate hyperbolic relation between 99mTc-GFR and SCr. Conclusion C-G GFR is most closely related to 99mTc-GFR among eGFR from SCr, C-G formula may be a suitable method for eGFR of Chinese inpatients with CKD when SCr is measured by enzymatic method.

    Abstract3130)      PDF(pc) (12513KB)(1671)       Save

    Objective To observe the progression of renal tubulointerstitial fibrosis in rat unilateral ureteral obstruction (UUO) models, and investigate the changes in expression of renal fibrosis-related proteins during the pathological course. Methods Thirty-two SD rats were randomly divided into sham-operation group (n=16) and UUO model group (model group, n=16). Rats were sacrificed 2, 5, 9 and 14 d after operation (after model establishment for model group) (n=4 for each day), and the renal tissues of the operated side (obstructed side for model group) were obtained. HE staining, Masson staining, immunohistochemical staining and Western blotting were used to evaluate the degree of renal tubulointerstitial fibrosis and detect the expression of α-smooth muscle actin (α-SMA), fibronectin (FN), vitamin D receptor (VDR) and transforming growth factor-β1 (TGF-β1) in renal tissues. Results Histological observations of renal tissues revealed that the degree of renal tubulointerstitial fibrosis gradually increased with time of ureteral obstruction. It was indicated by immunohistochemical staining that the percentages of area with positive α-SMA and FN in renal interstitium of model group, which gradually increased with time of ureteral obstruction and reached the peak 14 d after model establishment, were significantly higher than those of sham-operation group at each time point after model establishment (P<0.05). Western blotting analysis demonstrated that the relative expression of α-SMA and TGF-β1 at each time point after model establishment in model group was significantly higher than that in sham-operation group (P<0.05), while the relative expression of VDR was significantly lower than that in sham-operation group (P<0.05). The relative expression of α-SMA in renal tissues of rats in model group significantly increased on the second day after model establishment, and the relative expression of α-SMA and TGF-β1 in model group was 12.7 times and 8.8 times respectively of that in sham-operation group on the fourteenth day after model establishment, while the relative expression of VDR decreased to 3% of sham-operation group. Conclusion Significant interstitial fibrosis may emerge at 14 d after model establishment in rat UUO models.The expression of α-SMA in renal interstitium increases in the early stage of model establishment, indicating the activation of renal interstitial fibroblasts. The progression of decrease in expression of VDR indicates VDR may relate to renal interstitial fibrosis.

Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2 (AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmol/L and 14 414.3 pmol/L, respectively. Four hundred and seventytwo patients were divided into lower reaction group (AUC E2≤3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2>3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01)and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P>0.05). Conclusion Sustained supraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.
