Objective To compare the application effect of intermittent androgen deprivation(IAD)and continued androgen deprivation(CAD)on advanced prostate cancer and influence on prognosis.Methods The patients with advanced prostate cancer were divided into treatment group(86 cases)and control group(62 cases)according to the cohort method.The treatment group was given IAD regimen(subcutaneous injection of 3.6 mg goserelin once every 28 days)combined with oral administration of flutamide(250 mg every 3 times a day)or combined with oral administration of bicalutamide(50 mg once a day),and the control group was treated with CAD regimen(bilateral orchiectomy combined with continuous flutamide or bicalutamide orally,with the same dosage as the treatment group).The observation follow-up time of both groups was ≥9 months.Efficacy,serum total testosterone(TT),prostate specific antigen(PSA)and vascular endothelial growth factor(VEGF)were compared between the two groups after treatment,and the side effects of treatment,quality of life[Functional Assessment of Cancer Therapy-Prostate(FACT-P)]and disease progression were evaluated.Results At 9 months after treatment,the objective response rates(ORR)in treatment group and control group were 30.99％(22 cases/71 cases)and 29.09％(16 cases/55 cases),and the disease control rates(DCR)were 71.83％(51 cases/71 cases)and 69.09％(38 cases/55 cases)respectively(P＞0.05).Serum TT levels in treatment group and control group were(25.53±9.44)and(22.51±8.28)ng·dL-1,PSA levels were(4.48±1.02)and(4.32±0.95)ng·mL-1,and VEGF levels were(121.03±35.26)and(118.65±33.42)pg·mL-1 respectively(all P＞0.05).The incidence rates of hot flash in treatment group and control group were 21.13％and 56.36％,the incidence rates of breast swelling pain were 16.90％and 34.55％,and the incidence rates of osteoporosis were 8.45％and 25.45％respectively(all P＜0.05).The scores of physical condition of FACT-P in treatment group and control group were(24.15±4.22)and(20.28±3.71)points,the scores of life condition were(20.28±2.94)and(17.81±2.84)points,scores of prostate cancer specific(PCS)module were(33.21±6.32)and(28.42±5.43)points,respectively,the difference were all statistically significant(all P＜0.05).The cumulative progression-free survival rates in treatment group and control group were 61.97％and 58.18％(P＞0.05).Conclusion IAD is as effective as CAD in the treatment of advanced prostate cancer and has a similar effect on the prognosis of patients,but the former one has fewer side effects of treatment and helps to improve the quality of life of patients.

Objective To investigate the factors influencing prognosis in patients with acute myocardial infarction complicated with cardiogenic shock undergoing primary percutaneous coronary intervention(PPCI).Methods Patients with acute myocardial infarction complicated with cardiogenic shock who underwent PPCI at our hospital between January 2015 and December 2019 were enrolled.Clinical baseline characteristics,coronary angiography and PCI-related parameters,and mechanical support information were collected.The patients were followed up for one year and divided into survival and death groups based on their survival status within one year.Differences in various factors between the two groups were compared.Results A total of 40 patients were enrolled,including 26 in the survival group and 14 in the death group.There were no differences in baseline data,diagnosis,risk factors,and comorbidities between the two groups.The survival group had a lower heart rate and higher blood pressure trend at admission compared to the death group.Myocardial enzymes were significantly lower in the survival group compared to the death group(median CK peak:496.00(198.25,2 830.00)U/L vs.3 040.00(405.75,5 626.53)U/L,P=0.003;median CK-MB peak:52.65(31.75,219.50)U/L vs.306.00(27.25,489.63)U/L,P=0.006).When comparing coronary angiography and PCI-related indicators between the two groups,the survival group had a higher rate of complete revascularization compared to the control group(53.85％vs.21.43％,P=0.048).The survival group had a higher proportion of extracorporeal membrane oxygenation(ECMO)combined with intra-aortic balloon pump(IABP)support compared to the control group[38.46％vs.7.14％,P=0.034].Conclusions Survival in patients with acute myocardial infarction complicated with cardiogenic shock undergoing PPCI is associated with lower level of myocardial enzymes,ECMO combined with IABP support and complete revascularization.

AIM: To explore the effects of anti-vascular endothelial growth factor(VEGF)agents(Conbercept)before pars plana vitrectomy(PPV)on inflammatory cytokine levels of patients with proliferative diabetic retinopathy(PDR).METHODS: A total of 49 patients(49 eyes)who diagnosed with PDR at the First Affiliated Hospital with Nanjing Medical University from June 2017 to January 2018 were recruited and randomly divided into two groups. A total of 25 cases(25 eyes)who did not receive intravitreal injection before PPV were included in no-intravitreal injection of Conbercept(IVC)group, and 24 cases(24 eyes)who received IVC 5～7d before PPV were included in IVC group. The vitreous samples were collected from all the patients at the start of PPV. Levels of VEGF-A, monocyte chemotactic protein-1(MCP-1)and inflammatory cytokines in the vitreous humor were measured using Luminex technology.RESULTS: Compared with the no-IVC group, the level of VEGF-A decreased significantly(P<0.001), the concentration of IL-6(P=0.004), IL-8(P=0.002), IL-18(P=0.04)and TNF-α(P=0.03)increased remarkably in the IVC group. The other inflammatory cytokines in the vitreous humor showed no significant difference between the IVC and no-IVC groups.CONCLUSION: IVC before PPV can effectively decrease the concentration of VEGF-A, but had limited influence on the level of inflammatory cytokines in the vitreous humor of patients with PDR.

AIM: To analyze the correlations among parameters from iTrace visual function analyzer, Pentacam 3D anterior segment analysis system and lens opacities classification system(LOCS)Ⅲ in the assessment of lens opacity of age-related cataract(ARC)patients.METHODS: A prospective cross-sectional study. A total of 104 ARC patients(104 eyes)in the department of ophthalmology of our hospital from May to August, 2021 were included. The cataracts of patients were graded based on LOCSⅢ using a slit-lamp. Opacity map grade(OMG)and dysfunctional lens index(DLI)were obtained by iTrace. Pentacam nucleus staging(PNS)and Scheimpflug images of lenses were acquired by Pentacam. The regional integrated density(IntDen)of Scheimpflug images was obtained by ImageJ. The normality and correlations of parameters were analyzed by SPSS 26.0.RESULTS: All the parameters were normally distributed except 3mm IntDen and IntDen of 6mm posterior subcapsular region. PNS positively correlated with nuclear color(NC)and nuclear opalescence(NO)(r=0.521, 0.440, all P<0.01). The 3mm IntDen positively correlated with NC and NO(rs=0.459, 0.450, all P<0.01). IntDen of 3mm nucleus region positively correlated with NC and NO(r=0.539, 0.543, all P<0.01). IntDen of 3mm posterior subcapsular region was negatively correlated with NC and NO(r=-0.315, -0.321, all P<0.01). 6mm IntDen positively correlated with NC and NO(r=0.321, 0.288, all P<0.01). 3mm DLI negatively correlated with NC, NO, and posterior subcapsular cataract(PSC)(r=-0.257, -0.234, -0.282, all P<0.01). 6mm DLI negatively correlated with NC, NO, PSC(r=-0.247, -0.304, -0.227, all P<0.05). 3mm OMG positively correlated with CC and PSC(r=0.268, 0.333, all P<0.01), and 6mm OMG positively correlated with CC and PSC(r=0.275, 0.245, all P<0.05). 3mm DLI negatively correlated with PNS and IntDen of 3mm nucleus region(r=-0.217, -0.197, all P<0.05).CONCLUSION:Each lens opacity assessment system had its own advantages. Taking all parameters into comprehensive consideration is conducive to objectively eraluate the opacity degree of each area of the lens and provide references for clinical work.

The risk of plague epidemics and relapse of various types of plague foci persists in Inner Mongolia Autonomous Region. For Marmota sibirica plague foci, the animal plague has not been found but antibody has been detected positive. Nowadays, Marmota sibirica has been increasing in population and distribution in China. In bordering countries Mongolia and Russia, the animal plague has been continuously prevalent. For Spermophilus dauricus plague foci, the animal plague has been taken place now and then. Compared to the above foci, the animal plague is most prevalent in Meriones unguiculatus plague foci and frequently spread to humans. Due to higher strain virulence and historical disaster in Marmota sibirica plague foci and Spermophilus dauricus plague foci, plague prevention and control should be strengthened on these foci. In addition to routine surveillance, epidemic dynamics need to be further monitored in these two foci, in order to prevent their relapse and spread to humans.

Objective    To introduce a new type thoracic vest designed according to the incision characteristics of female patients undergoing totally thoracoscopic cardiac surgery. Methods    Sixty-one female patients undergoing totally thoracoscopic cardiac surgery from February 2019 to May 2020 in our department were enrolled. All female patients had hypermastia and (or) mastoptosis which covered the incision. They were randomly divided into a research group (group A, n=32) and a control group (group B, n=29). The group A used the new type thoracic vest, while the group B used the traditional single shoulder belt. The degree of satisfaction, visual analogue scale (VAS) score 24 hours after the thoracic drainage tube removed, the average time-consuming of dressing change, dressing frequency and the incision infection rate were compared between two groups. Results    The degree of satisfaction in the group A was higher than that of the group B (P<0.001). The VAS scores of pain, average time-consuming of dressing change and dressing frequency in the group A were less or lower than those of the group B (P<0.001). There was no statistical difference in the incision infection rate between the two groups (P=0.214), but incision infection rate of the group A was lower than that of the group B. Conclusion    The new type thoracic vest seems to be more beneficial for patients than traditional single shoulder belt. It is easy to use, increases the psychological satisfaction of patients, reduces the pain and the incision infection and improves work efficiency, which is worthy of clinical application.

OBJECTIVE: To detect the relationship between CTGF in the bone marrow of MM patients and osteolytic lesion of myeloma, moreover, to investigate the clinical significance of CTGF in MM. METHODS: Fifity-four MM patients treated in our hospital from March 2019 to April 2020 were enrolled, and 28 healthy volunteers were selected as the control group. The plasma in bone marrow of the patients was collected, and the ELISA was used to detect the level of CTGF in bone marrow plasma and the relationship between its and clinical characteristics were statistically analyzed. RESULTS: The CTGF level of MM patients was significantly higher than those in the healthy control group (P<0.001); the CTGF level in male patients was higher than that in female patients (P=0.007); the CTGF level in MM patients with osteolytic lesions was significantly higher than patients without osteolytic lesions and controls (P=0.007, P=0.001). The CTGF level in MM patients was positively correlated with the number of bone lesions (P<0.001, r=0.52). CTGF levels in patients with ≥3 bone lesions were significantly higher than those with <3 bone lesions and without bone lesions (P=0.014, P=0.002). ROC curve result showed that CTGF expression level shows a significant diagnostic value for MM bone disease (P<0.001). CONCLUSION The abnormally high expression of CTGF level in MM patients is related to the degree of myelomas osteolytic lesions and can reflect the progress of MM.

Objective To investigate the genetic variation of Eurytrema pancreaticum isolated from goats in Huaihua City, Hunan Province. Methods The partial sequence of mitochondrial cytochrome I (pcox1) and ribosomal 18S rRNA genes were amplified using a PCR assay in E. pancreaticum isolates from goats in Huaihua City, Hunan Province, and the PCR amplification products were sequenced. Then, the gene sequences were subjected to genetic variation and phylogenetic analyses. Results The sequences of the pcox1 and 18S rRNA genes were 430 bp and 1 857 bp in length in 18 E. pancreaticum isolates from goats in Huaihua City, Hunan Province, and there were 14 and 35 variation sites in pcox1 and 18S rRNA gene sequences, with intra-species genetic variations of 0 to 1.4% and 0 to 0.8%, respectively. The sequences of pcox1 and 18S rRNA genes had 99.0% to 99.8% and 99.5% to 99.8% homologies with those from E. pancreaticum Chinese strain recorded in the GenBank database. Consistent phylogenetic analysis results were found based on pcox1 and 18S rRNA genes. The 18 E. pancreaticum isolates from goats in Huaihua City were clustered into a clade with the known E. pancreaticum isolates registered in GenBank, and the clade with these 18 E. pancreaticum isolates was close to the clades with Eurytrema species and far from the clades with other trematodes. Conclusions The E. pancreaticum isolates from goats have a low genetic variation in Huaihua City, Hunan Province. Mitochondrial pcox1 and ribosomal 18S rRNA genes may serve as molecular markers for the studies on the genetic variation in goat-derived E. pancreaticum.

The purpose of this study is to analyze the family's clinical data of 22 children who were given an intended clinical diagnosis of Duchenne muscular dystrophy (DMD), and to explore the clinical value of next-generation sequencing (NGS) in the molecular diagnosis of DMD. The probands were simultaneously tested by NGS for a gene panel associated with hereditary neuromuscular disease and multiplex ligation-dependent probe amplification (MLPA) for the Dystrophin gene. The exon deletion/repetition mutations of the Dystrophin gene determined by both methods were compared and the point mutations of the Dystrophin gene were verified by Sanger sequencing. Dystrophin gene mutations were found in all the 22 probands, including 14 exon deletion/repetition mutations and 8 point mutations/minor variations. The results of MLPA detection were consistent with those of NGS. The results of Sanger sequencing showed that the point mutations and minor variations determined by NGS were correct. One missense mutation (c.6290G>T), 1 nonsense mutation (c.3487C>T) and 4 minor deletion-induced frameshift mutations (c.1208delG, c.7497_7506delGGTGGGTGAC, c.9421_9422delAA and c.8910_8913delTCTC) had not been reported in the Human Gene Mutation Database, and thus were considered as novel mutations of the Dystrophin gene. The results of this study showed that NGS can detect variations in the Dystrophin gene, including exon deletion/repetition, point mutation, minor deletion and intron mutation. Therefore, NGS is of certain clinical value in the molecular diagnosis of DMD and is worthy of recommendation.
