Objective To evaluate the diagnostic value of 99mTc-dimercaptosuccinate acid(DMSA) renal cortical scintigraphy for the identification of distinguishing between upper urinary infection(UUTI) and lower upper urinary infection(LUTI).Methods Two hundred and seventy-five children (111 males,164 females)ranging from 44 days to 15 years old,presented with urinary tract infection underwent 99mTc-DMSA renal cortical scintigraphy.The images were scored as normal (indicating LUTI) and abnormal (indicating acute pyelonephritis or renal scarring).Results Of 275 children with UTI,95 cases had normal images diagnosed as LUTI,41 males,54 females;and 180 cases had abnormal images,70 males,110 females.One hundred and seventy-four cases were diagnosed as acute pyelonephritis,6 cases were diagnosed as renal cortical scars,56 cases were single renal involved and 118 cases were both renal involved,and 22 cases repeatedly underwent renal cortical scanning after therapy.Sixteen of 18 cases with acute pyelonephritis completely recovered normal or obviously ameliorated after 0.5 to 2.0 years,2 cases did not show any improvement after 0.5 to 1.5 years,4 cases with renal scarring,and showed little change on repeated images after 1.0 to 1.5 years.Conclusions The 99mTc-DMSA renal scintigraphy is very useful in differentiating the children with urinary tract infection.It also can be used to determine the extension,degree and nature of UUTI,and might play an important role in the treatment and follow-up observation in children with UUTI.

Objective　To understand the overall under-reporting of cause of death monitoring in Hainan Province, and to provide a scientific basis for evaluating the data from death registration report and health planning in Hainan. Methods　Multi-stage cluster random sampling was used, all towns/streets in cities and counties of the province were ranked from highest to lowest in terms of crude death rate, divided into high, medium and low levels (the number of each level was basically the same), and one was randomly selected from each level. A total of three towns/streets were used as survey areas, and all households in the area were survey households. Death information of resident population during 2018-2020 was collected and compared with routine surveillance data for the same period. The under-reporting rate was calculated, and comparison between groups was performed by chi-square. Results　A total of 12 583 death cases were investigated from 2018 to 2020, and the average mortality was 621.48/105. 4 809 cases were missed with the total under-reporting rate of 38.22%. The under-reporting rate from 2018 to 2020 were 39.75%, 39.99% and 34.77% (χ2=30.404, P<0.01) respectively. The under-reporting rate in eastern and central and western areas were 30.33%, 30.10% and 60.15% (χ2=931.901, P<0.01) respectively. The negative rate were different in different years old group (χ2=14.834, P<0.05). Of the 4 809 under-reported cases, as many as 93.49% died at home, and the composition of deaths in hospitals was about 10 times higher in the center than in the east and west, and the proportion of those who died in hospital in central areas was about 10 times higher than in eastern and central areas. Conclusions　More than half of the cities and counties in Hainan Province have improved the completeness of cause of death surveillance data. The under-reporting rate in age group <5 years are still high, and regular under-reporting investigations are still needed to strengthen the reporting and management of death information.

Objective To explore the incidence and distribution features of neonatal phenylketonuria(PKU) and congenital hypothyroidism(CH) in Lianyungang area.Methods The heel blood samples dried on filter paper was collected from newborns after 72 hours.As the screening indicators,PKU was detected through serum phenylalanine concentration(Phe) detection by Guthrie′s bacterial inhibition assay and CH was detected through serum thyroid stimulating hormone(TSH) levels detection by time-resolved fluorometry(TRFIA) or enzyme linked immunosorbent assay(ELISA).Results Sixty-four children with CH were diagnosed and the rate of CH was 1∶2423,41 patients were examined by thyroid gland nuclein kinescope picture,among which there were 23 patients whose thyroid glands were unusal.These patients lived in 45 towns(streets),which had no difference between men and women,city and country side.A couple of twins were screened for CH;15 cases of PKU was detected with an incidence of 1∶10 339.These patients′ parents were neither consanguineous marriage nor dominance hereditary family history.Their physical and mental development were similar to the same age children after interventive treatment.Conclusions The distribution of CH and PKU is diffuse in Lianyungang.Neonatal screening is the only valid means to find patients with CH and PKU.

ObjectiveTo analyze the risk factors of nosocomial infection of patients with spinal cord injury.MethodsRetrospective surveys of nosocomial infection including risk factors, pathogen analysis and drug sensitivity tests were carried out for 88 cases with spinal cord injury in our hospital from 1996 to 2002.ResultsIt showed that the rate of nosocomial infection was 90.91% with 46.59% of urinary tract infection and 32.95% of respiratory tract infection. Nosocomial infection was closely related with such factors as the disease of spinal cord, the use of antibiotics, invasive operation, age and disturbance of disease.ConclusionReducing risk factors and using antibiotics reasonably are effective measures to reduce nosocomial infection of patients with spinal cord injury.

Objective To assess the outcomes of modified spiral ileal orthotopic neobladder.Methods From January 1998 to January 2008, 32 patients (all male) underwent radical cystectomy and spiral ileal orthotopic substitution for muscle invasive bladder cancer. A segment of 40 to 45 cm ileal loop was isolated, detubularized, and reconfigured in spiral shape to form a pouch. Bilateral ureters were reimplanted by inserting the 1 cm distal segment into the pouch to form a Split-Cuff nipple.The bottom of the pouch was opened and anastomosed with the urethra (4 stitches). Results There were no perioperative deaths. The mean operative time was 281.2±48.7 min. Blood loss was 545.4±181.9 ml. Twenty cases required a blood transfusion, the mean volume of intraoprative blood transfusion was 430.8±235.9 ml. The average hospital stays were 26.8±9. 7 days. Rate of daytime continence was 93. 7% (30/32) while nighttime continence was 81.3% (26/32). Urodynamic studies were carried out in 23 cases 6 months after surgery. Neobladder capacity at first desire to urinate was 315.0± 33.4 ml(270-420 ml). The maximum neobladder capacity was 490. 3±39.7 ml(350-600 ml).The maximum flow rate (Qmax) was 16.5 ± 5.9 ml/s. Full resting pressure was 22. 5 ± 11.8 cm H2O. Peak voiding pressure was 78.3 ± 14.7 cm H2O. After mean 58. 4 months' follow up (range 22 to 132), 4 cases died of metastasis of bladder cancer. Conclusion Modified spiral ileal orthotopic neobladder is a reasonable option for treating invasive bladder cancer.

Objective To evaluate the effect of rapamycin on proliferation and cell cycle of human bladder cancer cell line 5637. Methods Total?ly 5637 cells were maintained in RPMI 1640 containing 10%fetal bovine serum,100 U/mL penicillin and 100μg/mL streptomycin for adherent cul?ture. Cells were grown at 37℃in a 5%CO2 incubator. The 5637 cells were treated with various concentrations of rapamycin solution(50 nmol/L, 100 nmol/L,200 nmol/L,and 400 nmol/L). The control group was daily treated with single RPMI 1640 without medication. The growth repression rate for 5637 cells was evaluated by MTT. Flow cytometry was used to investigate the effect of rapamycin of different concentrations on cell cycle of 5637 cells. Results Compared to the control group,rapamycin can inhibit the proliferation of 5637 cells in a concentration and time dependent manner. Rapamycin inhibited 5637 cells at G0/G1 thus inhibiting cell proliferation but not inducing apoptosis. Conclusion Rapamycin inhibited growth of 5637 bladder carcinoma cells and arrested cell cycle at G0/G1,indicating that mammalian target of rapamycin may play an important role in proliferation of 5637 cells and act as a new tumor therapeutic target in patients with bladder cancer.
