ABSTRACT

Objective@#To investigate the application of suprapubic lipectomy with a "Ω" incision to removal of the prepubic fat pad for the management of buried penis in obese adult patients.@*METHODS@#We retrospectively analyzed the clinical data on 20 obese adult patients with buried penis treated by suprapubic lipectomy via a "Ω" incision between August 2016 and September 2019.@*RESULTS@#The operations were successfully completed in all the cases, with a mean operation time of 3.7 ± 0.6 hours and an average hospital stay of 8.3 ± 3.3 days. There were no such severe surgery-related complications as hematoma, urethral injury, or fat embolism in any of the cases. Fat liquefaction-related superficial wound infection developed in 1 patient postoperatively, which was cured by combined topical and systemic antibiotic therapy. A 3-month follow-up showed a 95% satisfaction of the patients with the postoperative appearance of the penis and suprapubic incision, but no complications such as ED, abnormal penile sensation, or penile retraction.@*CONCLUSIONS@#Suprapubic lipectomy with a "Ω" incision to remove the prepubic fat pad is an effective surgical approach to the management of buried penis in obese adult males, which is an anatomy-based surgical correction and has the advantages of slight injury, rapid recovery and few complications./.

ABSTRACT

Surgical correction can be considered for treating patients with a chronic phase of Peyronie's disease (PD) and persistent penile curvature. In clinical practice, some patients pay too much attention to surgical complications and refuse the recommended feasible surgical types. Meanwhile, they require operations according to their preferences. This study aimed to evaluate the effects of patients' own choice of surgical type on postoperative satisfaction. This retrospective study analyzed data from 108 patients with PD who underwent surgical correction according to doctors' recommendations or patients' own demands. The objective and subjective surgical outcomes were assessed. Patients' understanding of the disease was analyzed using a questionnaire survey. Objective measurements of surgical outcomes, including penile straightening, penile length, and sexual function, in patients who received the recommended surgery, were similar to those in patients who did not accept the recommended surgery. However, subjective evaluations, including erectile pain, discomfort because of nodules on the penis, and decreased sensitivity in the penis, were more obvious in patients who did not follow doctors' recommendations. In addition, a questionnaire survey showed that understanding PD and the purpose of surgery of patients who did not follow doctors' advice were inappropriate, as they did not conform to the principle of treatment. The present study showed that surgical correction seemed to be an objectively effective option in the management of patients in the stable chronic phase of PD. Low patient satisfaction might be related to patients' lack of correct understanding of the disease and its treatment strategy as well as unrealistic expectations.

ABSTRACT

Objective:To investigate the relationship between serum lipocalin-2 level and the risk of cardiovascular disease(CVD) in patients with type 2 diabetes.Methods:A total of 279 type 2 diabetic patients were enrolled in this study. Basic information and clinical data were collected. These patients were divided into CVD group and non-CVD group according to their cardiovascular disease status. Serum lipocalin-2 level was assessed by enzyme linked immunosorbent assay.Results:Compared to non-CVD group, serum lipocalin-2 level was significantly higher in CVD group( P<0.01). The Spearman correlation analysis showed that serum lipocalin-2 level was positively correlated with waist circumstance, diastolic blood pressure, uric acid, triglyceride, and HbA 1C( P<0.05), while negatively correlated with high density lipoprotein-cholesterol level( P<0.01). In addition, the univariate and multivariate logistic regression analysis revealed that serum lipocalin-2 was an independent risk factor for CVD( P<0.01)after adjustment for potential confounders. Moreover, receiver operating characteristic curve analysis demonstrated that the area under curve value of lipocalin-2 was 0.74, with the optimal cutoff value of lipocalin-2 66.84 ng/mL. Conclusion:Serum lipocalin-2 is closely associated with CVD in patients with type 2 diabetes, which might be considered as one of the predictors for CVD in type 2 diabetes mellitus.

ABSTRACT

To explore and analyze the possible mechanism of liver injury in patients with coronavirus disease 2019 (novel coronavirus pneumonia, NCP). The correlation between ALT, AST and other liver enzyme changes condition and NCP patients' disease status reported in the literature was comprehensively analyzed. ACE2 expression in liver tissue for novel coronavirus was analyzed based on single cell sequencing (GSE115469) data. RNA-Seq method was used to analyze Ace2 expression and transcription factors related to its expression in liver tissues at various time-points after hepatectomy in mouse model of acute liver injury with partial hepatectomy. -test or Spearman rank correlation analysis was used for statistical analysis. ALT and AST were abnormally elevated in some patients with novel coronavirus infection, and the rate and extent of ALT and AST elevation in severe NCP patients were higher than those in non-severe patients. Liver tissue results of single cell sequencing and immunohistochemistry showed that ACE2 was only expressed in bile duct epithelial cells of normal liver tissues, and very low in hepatocytes. In a mouse model of acute liver injury with partial hepatectomy, Ace2 expression was down-regulated on the first day, but it was elevated up to twice of the normal level on the third day, and returned to normal level on seventh day when the liver recovered and hepatocyte proliferation stopped. Whether this phenomenon suggests that the bile duct epithelial cells with positive expression of Ace2 participate in the process of liver regeneration after partial hepatectomy deserves further study. In RNA-Seq data, 77 transcription factors were positively correlated with the expression of ACE2 (r > 0.2, FDR < 0.05), which were mainly enriched in the development, differentiation, morphogenesis and cell proliferation of glandular epithelial cells. We assumed that in addition to the over activated inflammatory response in patients with NCP, the up-regulation of ACE2 expression in liver tissue caused by compensatory proliferation of hepatocytes derived from bile duct epithelial cells may also be the possible mechanism of liver tissue injury caused by 2019 novel coronavirus infection.

ABSTRACT

Objective: To investigate the effect of low molecular weight heparin sodium combined with magnesium sulfate in the treatment of patients with severe preeclampsia


Study Design: An experimental study


Place and Duration Of Study: The Department of Obstetrics and Gynecology, The Affiliated Hospital, North China University of Science and Technology, from April 2016 to July 2017


Methodology: Patients with severe preeclampsia were randomly divided into observation group [52 cases] and control group [51 cases]. In the control group, magnesium sulfate were used, but in observation group low molecular weight heparin sodium were added. After treatment of 7 days, serum TGF-beta1, VCAM-1, ES levels and endothelial function markers of NO and ET-1 changes were compared between the two groups.The delivery status after treatment was observed in both groups


Results: After treatment of 7 days, serum TGF-beta1 and NO levels in the observation group were higher than those in control group [both p<0.001], and VCAM-1, ES, ET-1, ET-1/NO levels in observation group were lower than those in control group [all p<0.001]. Among the patients who delivered live births, observation group had a longer delivery gestation age after treatment than that of control group [p=0.038]; placental quality, body mass and 1 minute Apgar score of surviving newborns in observation group were all higher than those in control group [all p<0.001]


Conclusion: Low molecular weight heparin sodium combined with magnesium sulfate may improve the prognosis of neonates by reducing the infiltration ability of cytotrophoblasts and regulating endothelial cell function

ABSTRACT

Objective@#To detect 20 common deafness gene mutations in non-syndromic hearing loss patients in China using the melting curve method, and analyze and summarize the mutation data to explore the clinical value of this method.@*Methods@#The real-time fluorescence PCR melting curve method was used to detect 20 common mutations of four deafness genes(GJB2,GJB3,SLC26A4 and mtDNA) in 492 patients with non-syndromic hearing loss recruited between March 2014 and September 2016 from the Otolaryngology Department of Xiangya Hospital, Central South University(283 males and 209 females, the age ranged from 1 to 48 years old). The Sanger sequencing method was used to compare the sensitivity, specificity, positive predictive value, negative predictive value, and total coincidence rate of the deafness mutation detected by the real-time fluorescence PCR melting curve method.@*Results@#A total of 492 samples were detected. 193 wild-type samples, 93 homozygous mutant samples, 145 heterozygous mutant samples, 59 composite heterozygous mutant samples and 2 samples with unknown mutations were detected using the real-time fluorescence PCR melting curve method within the range of 20 gene mutations, whichwere identical to the Sanger sequencing results.The two samples were detected as unknown mutations by the real-time fluorescent PCR melting curve method were confirmed by Sanger sequencing, including a composite heterozygous mutant sample and a homogenous mutation sample. GJB2 c.235delC and SLC26A4 c.919-2 A>G were the most common hotspot mutations in this study, followed by mtDNA m.1555 A>G. Compared with the Sanger sequencing method, the sensitivity, specificity, positive predictive value, negative predictive value, and total coincidence rate of the real-time fluorescence PCR melting curve method were 100%, the Youden′s index was 1.0, and the Kappa value was 1.@*Conclusions@#The real-time fluorescence PCR melting curve method is suitable for the detection of deafness gene mutations. It has the advantages in terms of simple, rapid, high sensitivity and strong specificity and can accurately detect the 20 gene mutations of 4 common deafness genes in Chinese population, which is expected to be used for the clinical detection of deafness genes in the future.

ABSTRACT

Objective To evaluate sedentary lifestyles after school in children aged 7 to 12 year-old living in Guangzhou, and to explore the association between sedentary behaviors after school with cardiometabolic risk factors. Methods Using the method of stratified cluster random sampling, this study recruited 7 to 12 year-old primary students (n=4 294) in Guangzhou. The physical examination and questionnaire were used to collect the sedentary lifestyles after school and cardiometabolic risk factors, analyzing the impact of different aedentary behavoir time after school on cardiometabolic risk factors. Results The average sedentary time after school per day were 194.3 min (boys: 200.3 min; girls: 187.3 min). Inter-quartile ranges of sedentary time after school per day were ≤130.0, 131.0-180.0, 181.0-240.0, and ≥241.0 min/d. Controlling for confounding factors, the odd ratios (OR) of central obesity, overweight/obesity, high TC status, high TG status and high LDL-C status in the highest compared to the lowest quartile of sedentary time after school per day were 1.39 (95%CI:1.08-1.80), 1.44 (95%CI:1.16-1.80), 1.26(95%CI:1.05-1.51), 1.63(95%CI:1.34-1.98), 1.28(95%CI:1.06-1.55), respectively. Conclusions Sedentary lifestyles have a positive relationship with childhood central obesity, overweight/obesity and dyslipidemia in primary school children. Therefore, it is essential to strengthen the intervention to the lifestyles of teenagers and reduce the sedentary behavior time of children and teenagers.

ABSTRACT

OBJECTIVE@#To investigate the advantages of minimally invasive surgery-transforaminal lumbar interbody fusion(MIS-TLIF) under Quadrant channel in the treatment of grade I and II degree degenerative lumbar spondylolisthesis.@*METHODS@#The clinical data of 100 patients with grade I and II degree degenerative lumbar spondylolisthesis treated from March 2014 to March 2017 were retrospectively analyzed. Among them, 50 patients were treated with MIS-TLIF, including 19 males and 31 females, aged from 44 to 73 years old with an average of (49.83±15.46) years old; course of disease from 6 months to 7 years with the mean of (22.18±4.74) months; L₄ slippage was in 30 cases and L₅ slippage was in 20 cases, the slippage vertebral pedicles were intact; according to Meyerding classification, 29 cases of I degree slip and 21 cases of II degree slip. Other 50 patients were treated with open-transforaminal lumbar interbody fusion(OPEN-TLIF), including 23 males and 27 females, aged from 40 to 77 years old with an average of(50.67±14.36) years old; course of disease from 6 months to 10 years with the mean of (20.56±5.37) months; L₄ slippage was in 33 cases and L₅ slippage was in 17 cases, the slippage vertebral pedicles were intact; according to Meyerding classification, 34 cases of I degree slip and 16 cases of II degree slip. The operation time, length of surgical incision, intraoperative blood loss, postoperative drainage, and serum creatine kinase(CK-MM) levels before surgery and 1 day after surgery were observed. Visual analogue scale(VAS), Japanese Orthopedic Association Score (JOA), and Oswestry dysfunction index (ODI) were compared between the two groups before and after surgery. According to the imaging data, the slip rate, intervertebral space height and slip angle of the two groups before and 12 months (last follow-up) were compared. Intervertebral fusion was evaluated according to lumbar X-ray and CT at 6 and 12 months postoperatively. The clinical effect was evaluated according to the MacNab criteria at 12 months after surgery.@*RESULTS@#All the patients were followed up for 12 months. In MIS-TLIF group, operation time, length of surgical incision, intraoperative blood loss, postoperative drainage were (118.48±21.97) min, (3.74±0.74) cm, (148.78±32.32) ml, (84.85±16.37) ml, respectively, CK-MM level was (72.31±9.79) μ/L before surgery and (415.12±25.89) μ/L at the first day after surgery. In OPEN-TLIF group, operation time, length of surgical incision, intraoperative blood loss, postoperative drainage were (115.40±11.94) min, (8.46±0.69) cm, (219.27±48.33) ml, (157.69±31.61) ml, respectively, CK-MM level was (75.48±10.73) μ/L before surgery and (506.69±37.86) μ/L at the first day after surgery. The intraoperative blood loss, postoperative drainage volume, length of surgical incision, and CK-MM level on the first postoperative day were lower in MIS-TLIF group than in OPEN-TLIF group(0.05). There were no significant differences in ODI, VAS, and JOA scores before surgery(>0.05). The ODI, VAS, and JOA scores were significantly improved after surgery(0.05). There was no significant difference in intervertebral fusion between groups at 6 and 12 months after operation(>0.05). According to the MacNab standard, 40 cases got excellent results, 7 good, 3 fair in MIS-TLIF group, and 35 cases got excellent results, 10 good, 5 fair in OPEN-TLIF group. One patient had incision exudation and delayed healing in MIS-TLIF group. And in OPEN-TLIF group, 1 patient had local muscle necrosis on the right side of L₅ and the bacterial culture of the secretions was negative in the different three times and the right internal fixation device was taken out after the second operation completely debridement, and finally obtained delayed healing.@*CONCLUSIONS@#The MIS-TLIF under Quadrant channel has advantage of minimally invasive trauma, less bleeding, faster function recovery and better effect in surgical treatment of grade I and II degree degenerative lumbar spondylolisthesis.

ABSTRACT

The development of non-small cell lung cancer (NSCLC) is a complex process which referring to multi-factor interaction.In this process,p53 gene regulates the normal growth of cells,but p53 gene after mutation can induce the occurrence of NSCLC,promote tumor distant metastasis,induce chemotherapy resistance,and cause poor prognosis of patients.Therefore,the restoration of normal expression of p53 gene is very significant for the treatment of NSCLC.In recent years,the rapid progress of p53 gene therapy has opened up a new way for the treatment of NSCLC.

ABSTRACT

Objective To explore the effect of lipoprotein(a) [Lp(a)] on in-stent restenosis and non-target coronary lesions in coronary artery disease (CAD) patients implanted with drug-eluting stents. Methods One hundred and seventy-four patients, diagnosed as CAD and underwent percutaneous coronary intervention (PCI) with the implantation of drug-eluting stents (DES), were enrolled in present study; all of them were performed another elective PCI or revascularization within 1-4 years after their previous procedures. Thirty-one of enrolled patients were discovered to have in-stent restenosis. The relationship between Lp(a) and in-stent restenosis and the development of non-target coronary lesions were analyzed in groups stratified by the presence of in-stent stenosis or Lp(a) levels, and the independent risk factors of both in-stent restenosis and non-target lesions were also analyzed by multivariate logistic regression analysis. Results In CAD patients with DES, Lp(a) level in patients with in-stent restenosis showed a significant increase than those with the Lp(a) level non-restenosis [(437.57±391.60) mg vs. (279.46±288.06) mg, P=0.04]. In following analysis comparing lipid profiles and coronary angiography results between low and high Lp(a) groups, the percentage of triple-vessel disease and left main plus triple-vessel disease appeared to be statistically higher in high Lp(a) group than those in low Lp(a) group (P=0.022). Multivariate logistic regression analysis revealed that high level of Lp(a) and much number of stents implanted were the independent risk factors for in-stent restenosis of DES. In comparing the characteristics of coronary angiography and results of quantitative coronary angiography, number of cases with non-target lesions, presence of in-stent restenosis, minimal lumen diameter and in-stent late lumen loss were all significantly higher in high Lp(a) group than those in low Lp(a) group (P<0.05), and high level of Lp(a) was again proved to be an independent risk factor for non-target lesions in patients with DES (P=0.001). Conclusion Elevated Lp(a) level is an independent risk factor for both in-stent restenosis and the development of non-target coronary lesions, and is closely related to the relapse and aggravation of coronary artery disease.
