Objective To investigate the minimal invasive management of cystitis glandularis with invasion of the ureteric meatus.Methods The clinical data of 18 cases were reviewed.Among the 18 cystitis glandularis patients,12 cases were invasion of bilateral ureteric meatus and 6 of unilateral ureteric meatus.Operation or drug treatment was performed on the diseases that can cause cystitis glandularis such as bladder stone,bladder neck stegnosis,external urethral meatus stegnosis and benign prostate hyperplasia.Sensitive antibiotic was administrated in all cases.After placing ureter catheter,transurethral plasma electro-resection was carried out in five patients whose ureteric meatus could be identified.In addition,of thirteen patients with ureteral orifice unable to be identified,there were ten cases with normal renal function,mitomycin was injected under affected membrana mucosa,and then the patient with ureteral orifice identified underwent transurethral plasma electro-resection after placing ureter catheter.On the other hand,the patient whose ureteral orifice still could not be recognized undertaken transurethral electro-resection at first,during which the ureter catheter was put once ureteral orifice had been detected,otherwise,the ureter catheter should be placed through cystoscope if nephritic colic emerged and hydronephrosis aggravated after operation.In those patients with kidney dysfunction,the ureter catheter was put by ureter discission or ureter replantation at first,the transurethral electro-resection could not be executed until the renal function recovered.Following all these procedure above,bladder instillation of drugs regularly,anti-infection and symptomatic treatment were administrated.Results One patient combined with bladder adenocarcinoma received cystectomy,of the other patients,six cases recurred and underwent electrotomy again resulting in no relapse.All nephrohydrops vanished or relieved obviously,nevertheless,urinary tract infection,haematuria and bladder-ureter backstreaming as the cardinal complication developed in some cases.Conclusion In the management of cystitis glandularis encroaching ureteric meatus,total or partial cystectomy can be avoided if ureter draining freely can be ensured,motivation removal,antiinfection,injection of drug under mucosa and preoperative diuresis conduce to the achievement of ureter catheter placing,transurethral plasma electro-resection is still effective methods in treating these cystitis glandularis.

Objective To investigate the expression of adamalysin-12 (ADAM-12) and PCNA in human bladder carcinoma and to investigate their correlation with different grades and stages of bladder cancer.Methods Biopsies of 15 normal bladder and 43 bladder tumors were analyzed.Immunohistochemistry was conducted to detect the expression of ADAM12 and PCNA in the biopsies.Results Postive expression signals of ADAM12 were detected significantly higher in the bladder cancer biopsies than that in the normal ones (P = 0.010).Those with lower histological grade had a higher expression level of ADAM-12 compared to the higher histological grades (P ＜0.001 ).Positive expression signals of PCNA were detected significantly higher in the bladder cancer biopsies than that in the normal ones (P = 0.026).Those with lower histological grade had a higher expression level of PCNA (P =0.014).There was a positive correlation between the expression of ADAM-12 and PCNA in bladder cancer (r =0.997,P ＜ 0.001 ).Conclusions The overexpression of ADAM-12 and PCNA in the biopsies of bladder tumors shows that protein expression of ADAM-12 and PCNA correlated with tumor stage and grade.Furthermore,ADAM-12 may be a promising biomarker of bladder cancer in the clinical implication.

Objective: To investigate the epidemiological characteristics of overseas imported dengue fever and malaria cases in Yunnan Province from 2015 to 2021, so as to provide insights into the prevention and control of overseas imported arthropod-borne infectious diseases. Methods: The data pertaining to imported dengue fever and malaria cases in Yunnan Province from 2015 to 2021 were collected from the Chinese Disease Prevention and Control Information System, and the temporal distribution, regional distribution, population distribution, sources, diagnosis and treatment of imported dengue fever and malaria cases were descriptively analyzed. Results: Totally 4 332 overseas imported dengue fever cases and 2 011 overseas imported malaria cases were reported in Yunnan Province form 2015 to 2021, which accounted for 30.09% of all reported dengue fever cases and 98.53% of all reported malaria cases. The number of overseas imported dengue fever and malaria cases peaked from August to November (83.13% of all imported dengue fever cases) and from April to July (59.08% of all imported malaria cases), and the cases were predominantly reported in Dehong Prefecture (50.99% and 58.88%), with farmers as the predominant occupation (40.21% and 67.93%). The dengue fever and malaria cases were mainly imported from Southeast Asia (99.04% and 88.21%), and the proportions of definitive diagnosis of dengue fever and malaria were 88.33% and 97.80% at township hospitals, respectively. Conclusions The number of overseas imported dengue fever and malaria cases peaked from August to November and from April to July in Yunnan Province from 2015 to 2021, and the cases were predominantly reported in Dehong Prefecture and imported from Southeast Asia, with farmers as the predominant occupation.

Objective To investigate the polymorphism of human cytomegalovirus (HCMV) UL144 gene of the low passage clinical isolates in Guangzhou and explore the role of UL144 gene in HCMV pathogenicity. Methods The clinical isolates of HCMV were obtained from the urine sample collected from those infants with intra-uterus HCMV infection in Guangzhou. The virus genome DNA was extracted. According to the genome sequence of Toledo, primers for UL144 gene were designed and used to amplify the complete open reading frames (ORF) of the UL144 gene in our 3 different clinical isolates. These ORFs of the UL144 gene were cloned into pMD18-T vector and their sequences were confirmed by sequencing. Bioinformatics methods were used subsequently to analyze the polymorphisms of these genes in different stains. Results Three HCMV low passage clinical isolates were successfully isolated, named D2, D3 and D52. As shown by PCR, all of these three strains contained UL144 ORF region. Three complete ORFs were amplified in total and their sequences were submitted to GenBank (Accession No.: DQ180368, DQ180382 and DQ180355). In D2, D3 and D52 isolates, their UL144 ORFs consisted of 531 nucleotides. DNA sequences were quite conservative,all variability were base substitution, and the amino acid sequences were high conservative, the rate of amino acid variability was 1.1%. There were no additional or deleted sites of posttranslational modification of UL144 protein in all clinical isolates. There were some differences in the secondary structure among different isolates. The isoelectric point of UL144 protein of all clinical isolates was 8.97. Conclusions All DNA and deduced amino acid sequences of UL144 gene share great similarity among Guangzhou HCMV clinical strains regardless of their polymorphism. It implies that maybe UL144 gene plays an important role in congenital infection.

OBJECTIVETo investigate whether S. aureus could activate NF-κB signaling pathway in human osteoblasts.

METHODSImmunoblot and electrophoretic mobility shift assay were used to detect the degradation of I-κBα and activation of NF-κB in human osteoblasts following infection with S.aureus, respectively, and there were investigated the activated state of NF-κB signaling pathway in human osteoblasts. In addition, enzyme-linked immunosorbent assay was used to measure the secretion of IL-6 in culture supernatants, which was represented as one of important cytokines in osteomyelitis, and an inhibitor of NF-κB, SN50, which was added to human osteoblasts culture prior to 1 hour at 50 µmol/L before the infection of S.aureus, was used to determine whether S.aureus-activated NF-κB signaling pathway regulates IL-6 secretion of human osteoblasts.

RESULTSS.aureus could induce the degradation of I-κBα (I-κBα(15 min)/I-κBα(0 min) = 0.409 ± 0.245 and I-κBα(30 min)/I-κBα(0 min) = 0.061 ± 0.010) and activation of NF-κB in human osteoblasts in a time and dose-dependent manner following infection. In addition, the secretion of IL-6 in the supernatants of human osteoblasts ((2.17 ± 0.11) µg/L) was suppressed by 50 µmol/L SN50 compared to without the addition of SN50 ((3.58 ± 0.31) µg/L) (F = 174.25, P < 0.05).

CONCLUSIONSS.aureus could activate NF-κB signaling pathway in human osteoblasts, which could regulate cytokines secretions of human osteoblasts.

OBJECTIVESymptomatic benign prostate hyperplasia (BPH) affects both the patients' and their wives' quality of life (QOL) due to lower urinary tract symptoms (LUTS) and related events. This study was to investigate the QOL of the wives of symptomatic BPH patients being evaluated for surgical treatment.

METHODSWe included 50 couples in this study, in which the husbands were symptomatic BPH patients referred for surgical treatment. The patients were asked to fill in the forms of IPSS and BPH impact index ( BPHII), while their wives investigated with a 7-item questionnaire. The data obtained were subjected to statistic analyses.

RESULTSLUTS of the BPH patients caused sleep disturbance in 12% of their wives, decreased social activity in 12%, inadequate sexual life in 20%, psychological stress in 38%, fear of prostate cancer in 68%, fear of surgery in 40% and insufficiency for essential tasks in 14%. The decrease in the QOL of the patients' wives was not correlated with the patients' scores on IPSS and BPHII (P > 0.05).

CONCLUSIONLUTS and related events of symptomatic BPH patients obviously decrease the QOL of their wives, but the severity of the patients' symptoms is not correlated with the decrease of their wives' QOL.

Guide wire plays an important role in the fixation of femoral neck fracture with dynamic hip screw (DHS). Breakage of a guide wire during operation is a very rare condition. We met such a dilemma in DHS fixation of a 54-year-old male patient who sustained Garden type IV fracture of the right femoral neck. The distal end of the guide wire broke and was entrapped in the fractured femoral neck. We tried to get the broken part out by a cannulated drill. Reaming was started with the cannulated drill slowly rotating around the guide K-wire until the reamer fully contained the target under fluoroscope. A bone curette was used to get the broken wire out but failed, so we had to use the cannuated drill to dredge this bone tunnel. Finally the broken wire end was taken out, mixed with blood and bone fragments. Through the existing drilling channel, DHS fixation was easily finished. The patient had an uneventful recovery without avascular necrosis of femoral head or non-union of the fracture at one year's follow-up. A few methods can be adopted to deal with the broken guide wire. The way used in our case is less invasive but technically challenging. When the guide wire is properly positioned, this method is very practical and useful.
