Objective:To explore the relationship between renal ultrasound shear wave elastography (SWE) and renal biopsy pathology in patients with primary glomerulonephritis (PGN).Methods:A total of 137 confirmed PGN patients admitted to Bin hai wan Central Hospital of Dongguan from January 2021 to March 2023 were selected as the study subjects for quantitative analysis of renal SWE and pathological examination of renal biopsy. The differences in renal elastic modulus among different pathological types, as well as the relationship between renal elastic modulus and pathological factors of renal biopsy and IgA nephropathy Lee grading, were analyzed.Results:IgA nephropathy, membranous nephropathy, and minimal degenerative glomerulopathy were the most common pathological types of PGN, and the difference in renal elastic modulus among the three was not statistically significant (all P>0.05). The maximum elastic modulus of the immune complex deposition positive group was greater than that of the negative group ( P<0.05). The average, median, and maximum elastic modulus of the group with severe degree of foot cell fusion were lower than those of the group with mild degree of foot process fusion (all P<0.05). The average and maximum values of elastic modulus in the group with mesangial eosinophil deposition were higher than those in the group without mesangial eosinophil deposition (all P<0.05), while the maximum value of elastic modulus in the group with pericystic fibrosis was lower than that in the group without pericystic fibrosis ( P<0.05). There was no statistically significant difference in the renal elastic modulus values among the Lee grading subgroups of 61 IgA nephropathy cases (all P>0.05), and there was no correlation between Lee grading and renal elastic modulus values ( P>0.05). There was no statistically significant correlation analysis between the renal elastic modulus value and the glomerular sclerosis rate, the degree of mesangial cell and matrix proliferation, and the percentage of renal tubular atrophy area (all P>0.05). Conclusions:SWE is expected to provide new imaging diagnostic indicators for monitoring pathological damage factors in PGN. SWE may not be able to efficiently monitor the pathological progression of IgA nephropathy.

Objective@#To explore the practice and effect of transparent supervision in the prevention and control of multidrug-resistant organism (MDRO).@*Methods@#Transparent supervision was introduced to intervene into the MDRO management of monitored departments. Such transparent supervision was aided by IT means, and transparent MDRO control indexes. These indexes included hand hygiene compliance rate, qualification rate of ATP detection of environmental object surface, implementation rate of main MDRO prevention and control measures, MDRO resistance rate, and nosocomial infection incidence. The data before and after the intervention were compared by Chi square test to evaluation the effect.@*Results@#After intervention, the hand hygiene compliance rate increased from 49.83% to 65.61% (χ2=47.389, P<0.001), and the qualification rate of ATP detection of environmental object surface increased from 48.50% to 83.33% (χ2=96.115, P<0.001). Meanwhile, such indexes as prescription of patient isolation, placement of isolation identifiers and that of specialized bedside equipments increased significantly(P<0.001). The MDRO detection rate decreased from 75.08% to 63.31% (χ2=28.123, P<0.001), and the incidence of nosocomial infection decreased from 4.77% to 3.47%(χ2=20.303, P<0.001).@*Conclusions@#The practice of transparent supervision could reduce the risk of MDRO transmission at hospitals effectively, proving its importance in ensuring medical quality and patient safety.

Objective To investigate the status of safe injection practice in primary medical institutions.Methods 55 primary medical institutions in Hubei Province were randomly selected,questionnaire survey on status of safe injection in primary medical institutions was conducted.Results A total of 55 questionnaires were distributed,50(90.91％) valid questionnaires were obtained.All valid questionnaires were from primary level medical institutions of Hubei Province,16 of which were from community health centers,17 from township health centers,and 17 from village health clinics.None of 50 primary medical institutions repeatedly used syringe and hemostix,all used disposable sterile syringe,only 7(14.00％) medical institutions used retraction type self-destructing syringe.Only 5 (10.00％) medical institutions were equipped with hand hygiene facilities and sharps containers,32 (64.00％) medical institutions didn't provide sharps containers on treatment carts,21 (42.00 ％) injection rooms didn't install hand-drying facilities,18 (36.00 ％)medical institutions didn't provide alcohol-based hand rub on treatment carts and didn't install hand-drying facilities in treatment rooms.Of sharp injures among health care workers (HCWs) reported in 2015,114 HCWs sustained 117 times of injuries,74 cases(63.25 ％) were caused by ampoule.Of medical waste disposal,there existed some problems,such as leakage and repeated use of sharps box,didn't close sharps box timely,as well as without providing sharp containers in locations where sharps might be produced.Conclusion There are a variety of hidden risks of unsafe injection in primary medical institutions,like insufficient facilities and unsafe disposal of medical waste.

Objective To explore the curative effect of stomatitis spray combined with 3M liquid dressing on degree II red buttocks in infants and summarize key points of nursing care. Methods From April 2012 to June 2016, 64 infants with degree II red buttocks were treated in our department. According to the admission time, the infants were divided into control and experiment groups in equal number. The control group was treated with zinc oxide ointment, and the experiment group with stomatitis spray combined with 3M liquid dressing. The curative effect, total effective rate, and wound healing time were compared after treatment between the groups. Results The curative effect and total effective rate of red buttocks in the experiment group were significantly better than those of the control group (P<0.05). Moreover, the wound healing time in the experiment group was obviously shorter than that of the control (P<0.05). Conclusions Compared to zinc oxide ointment, the stomatitis spray combined with and 3M liquid dressing is more effective in the treatment of severe red buttocks of the infants. Moreover, the latter is advantageous in wound healing time, compliance, treatment, and curative effect, which indicates its potential application in clinic.

Purpose To investigate estrogen receptor ( ER ) , progesterone receptor ( PR ) expression in PTEN-deficient endometrial carcinoma and to analysis the relationship of PTEN, ER and PR protein expression with histological grade, pathological staging and muscle invasive. Methods Immunohistochemistry EnVision was used to detect the expression of PTEN, ER and PR protein in 100 ca-ses of endometrial carcinoma. Results The rate of PTEN-deficient endometrial carcinoma was 52. 0% (52/100). The expression rate of ER, PR protein on PTEN-deficient endometrial carcinoma was 15. 4% (8/52), 19. 2% (10/52), respectively. And the expression rate of ER, PR protein on PTEN over-expression endometrial carcinoma was 72. 7% (8/11), 63. 6% (7/11), respectively. The rate of PTEN, ER and PR expression types shown PTEN-ER-PR- was 42. 0% (42/100), which was higher than other types (P <0. 05). Different PTEN, ER and PR expression types were well correlated with histological grade and pathological staging (P<0. 05), but not with muscle invasive. Conclusion Combined detection of PTEN, ER and PR may have an important reference value for prog-nosis and treatment of endometrial carcinoma.
