Objective To study the diagnosis and treatment of testicular cancer in cryptorchids. Methods The data of 10 patients with cryptorchid tumor treated at our hospital between 1986 and 2003 were retrospectively analyzed.Their average age was 40 years (range,32~55 years).Of these patients,1 had the testis in the inguinal area;3,in the scrotum (with a history of inguinal cryptorchidism) and 6,in the abdomen.Cryptorchidism occurred on the left in 2 cases,on the right in 5 and bilaterally in 3.Three patients presented with stage Ⅰ A disease,5 with stage Ⅰ B,and 2 with stage Ⅱ D. Results All the 10 patients received surgical treatment including radical tumor resection,radical tumor resection with retroperitoneal lymph node dissection (RPLND),and palliative operation.Pathology showed that 9 cases had seminoma and 1 had seminoma accompanied by embryonic carcinoma.Radiotherapy was performed in 8 cases,and radiotherapy plus chemotherapy,in 2 (including 1 with embryonic carcinoma).Postoperatively,6 patients were followed up for 6 months to 14 years with a mean of 5.2 years;these patients showed no evidence of tumor recurrence and metastasis. Conclusions Cryptorchid testes have a greater risk of malignant change than do normally descended testes,and early intervention is advocated to prevent malignant canceration.Even treated with orchidopexy or orchiectomy,the patient should be followed up lifelong.Most of cryptorchid tumors are seminomas, and the ideal treatment strategies are tumor resection and radiotherapy.

Objective To evaluate quantitatively the standing balance function of patients with lower limb prosthesis. Methods Twenty-two patients were divided into three groups according their conditions: group 1 consisted of patients with one leg amputated, group 2 consisted of patients with one amputated at high level, group 3 consisted of patients with both thighs amputated, and twenty-one normal subjects served as control. Parameters including the sway magnitude of gravity center, circumference area, drift in X vector, etc., were recorded and analyzed. Results The data obtained revealed that the sway magnitude, circumference area were increased, in all the cases, especially in those with lower limb prosthesis at both sides. Compared to the control group, the difference was significant( P

Objective:To investigate the correlation between hyperreflective dots (HRD) and lipid levels and systemic inflammatory factors in patients with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO).Methods:A cross-sectional clinical study. From December 2016 to June 2020, 118 eyes of 118 patients with retinal vein occlusion diagnosed in the Department of Ophthalmology, Central Theater Command Hospital of People's Liberation Army were included in the study. Among them, 67 cases of BRVO and 51 cases of CRVO were divided into CRVO group and BRVO group accordingly. Peripheral venous blood was drawn from the patients within 3 days after the eye examination to detect the percentage of neutrophils, monocytes, hypersensitive C-reactive protein (CRP), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and lipoprotein(a). The ratio of monocytes to high-density lipoprotein (MHR) was also calculated. The 3D OCT-2000 instrument from Topcon (Japan) was used to measure the central retinal thickness (CRT) and the numbers of HRD. According to the different distribution position, HRD is divided into inner retina HRD, outer retina HRD, and total retina HRD.The independent sample t test was used to compare the continuous variables of the two groups, and the χ2 test was used to compare the rates. The correlation between HRD counts and blood lipid levels and peripheral blood inflammation indicators in patients with different types of RVO was analyzed by Spearman correlation analysis. Results:The average age of patients in the BRVO group and CRVO group were 60.1±9.5 and 53.6±15.7 years, respectively; the prevalence of hypertension was 53.7% (36/67) and 24.5% (12/51), respectively. Comparison of age ( t=2.634) and prevalence of hypertension ( χ2=11.298) between the two groups showed statistically significant differences ( P<0.05). Gender ( χ2=2.000), course of disease ( t=-1.101), prevalence of diabetes ( χ2=1.315), eye category ( χ2=1.742), baseline visual acuity ( t=1.792), intraocular pressure ( t=0.708), CRT ( t=1.318), and peripheral blood include the percentage of neutrophils, the absolute number of monocytes, CRP, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lipoprotein(a), MHR ( t=-0.559, 1.126, 0.579, 1.299, -0.134, 0.556, 1.230, -0.267, 0.483), the difference was not statistically significant. Correlation analysis showed that the HRD counts in the outer retina of BRVO patients were positively correlated with total cholesterol ( r=0.289, P=0.036); the HRD in the inner retina and total HRD counts of CRVO patients were positively correlated with CRP ( r=0.406, 0.343; P=0.004, 0.014). There was no correlation between HRD counts and percentage of neutrophils, absolute number of monocytes, triglycerides, high-density lipoprotein, low-density lipoprotein, lipoprotein(a), and MHR ( P>0.05). Conclusion:The number of HRD is related to the blood lipid level in BRVO patients and CRP (an inflammatory index) in CRVO patients.

BackgroundRetinitis pigmentosa (RP) has the genetic and phenotype heterogeneity.To determine the disease-causing gene is a foundation of gene therapy.Objective This study was to localize the pathogenic gene and screen the gene mutation associated with Han Nationality autosomal dominant retinitis pigmentosa (ADRP) in a Chinese family.MethodsTwenty-one families enrolled this study,including 12 patients with ADRP and 9 individuals with normal phenotype.Perimetry,fundus examination,electrooculogram ( EOG ) and electroretinogram (ERG) were performed in 12 patients.Genetic linkage analysis was performed on the subjects in all known genetic loci related to ADRP with a panel of microsatellite markers.Subsequently,the mutation screening of rhodopsin gene was screened by direct DNA sequencing.This study was approved by Ethic Committee of Zhongnan Hospital of Wuhan University.Informed consent was obtained from each subject.ResultsThe fundus appearance of the proband was in accordance with the ADRP,and the EOG and ERG showed undetectable.Contractive visual field also was exhibited in the proband.Linkage analysis showed that the maximum logarithm of the odds(LOD) score reached 3.6671 at marker D3S1292 at recombination fraction θ =0.0.The results of direct DNA sequencing revealed a C→ G transversion mutation at codon 53 in exon 1 of rhodopsin gene,which resulted in a proline to arginine change (Pro53Arg) in 12 patients.However,no similar mutation was found in the unaffected members of this family.ConclusionsThe missence mutation Pro53Arg in rhodopsin gene cosegregate with the RP disease.It is determined to be a pathogenic factor of this ADRP family.

Objective: To investigate the osteointegration and osteoinduction of nano hydroxyapatite/bioglass ( nHA/BG ) gradient nanofilm on the surface of titanium ( Ti) prepared by hypotherm sintering and plastic deformation. Methods:Hypotherm sintering was used to produce nHA/BG gradient coating followed by soaking in the simulated body fluid. Ti implants with gradient coatings were planted in femoral condyles at one side of 12 New Zealand rabbits and the untreated Ti implants were planted at the other side as the controls. 1, 3 and 6 months after implantation, the animals were sacrificed after X-ray examination and the tissues around the implants from the 3 month group were used for the preparation of hard tissue section and ground section. New bone formation was observed by tetracycline fluorescence staining. Von Gieson staining was used to observe the osteointegration at the interface between bone and im-plant. Results:The gradient coatings were porous and composed of irregular rod-like nano-HA crystals. Animal study showed well es-tablished osteointegration between the gradient coating and more novel bone was found around the implants with gradient coatings. Conclusion:Osteointegration and ostioinduction of Ti implant can be enhanced by nanostructured surface with gradient coatings of nHA/BG.

Objective To explore the correlation of the gene polymorphism of the two single nucleotide polymorphisms(SNPs)rs1443434andrs925489onforkheadboxEl(FOXE1)withthehighnormalthyroidstimulating hormone ( TSH) level in Chinese Han population. Methods 1 400 subjects with normal serum TSH and thyroid peroxidase antibody(TPOAb) levels were included. According to TSH or TPOAb levels, the subjects were divided into high normal TSH group(H-TSH group,n=195) and normal TSH control group(TSH control group,n=1 205) or high normal TPOAb group ( H-TPOAb group, n=711 ) and low normal TPOAb group ( L-TPOAb group, n=689 ) , respectively. The genotypes on the two SNPs of all the subjects were performed by whole-genome genotyping chips. Results There were significant differences in rs925489 genotypic distributions and allele frequencies between H-TSH group and TSH control group(both P<0. 05). The genotype TT and allele T in H-TSH group were significantly higher than those in TSH control group(89. 75% vs 83. 15%, 94. 62% vs 91. 29%). The normal TSH levels were positively associated with rs925489 genotypic distributions after adjustment for sex, age, and high density lipoprotein cholesterol(P<0. 01). There were no significant differences in rs1443434 genotypic distributions and allele frequencies between two TSH groups or two TPOAb groups. Conclusion FOXE1 rs925489 gene polymorphism may be correlated with the high normal TSH level in Chinese Han population.
