ABSTRACT

Objective To determine the epidemiological characteristics of measles in Jinshan District of Shanghai in 2002‒2019. Methods This study was a secondary data analysis using measles surveillance system and epidemiological case reports in Jinshan District from January 2002 through December 2019. Temporal characteristics of the disease onset was determined by a concentration method. ArcGis 10.4 and SaTScan 9.6 software were used for spatiotemporal clustering scanning analysis. Results From 2002 through 2019, a total of 289 cases of measles were reported in Jinshan District, Shanghai, with an average annual incidence of 2.24 per 105. The annual incidence fluctuated from 0 to 11.27 per 105. The highest incidence was recorded in 2005 (11.27 per 105), followed by a decline; however, there was a rebound in 2008 (5.26 per 105) and 2015 (3.30 per 105). The concentration M was determined to be 0.62, showing a clear seasonality concentrated in February to May. The spatiotemporal scan found that spatial and temporal clusters were more likely to occur in the areas with higher population density such as Zhujing Town and Shihua Community and between 2002 and 2009. The majority of measles cases were infants and children under the age of 1 and adults aged 20‒39 years. Approximately 66.78% of measles cases reported unknown vaccination history. In addition, in children aged 8 month to 4 years, the vaccination rate of measles-containing vaccines in the domestic migrants was much lower than the local residents (χ2=4.44, P=0.035). Conclusion The incidence of measles in Jinshan District presents a downward trend. The population affected has a "two-way displacement", which is concentrated in the more populated areas. It is necessary to strengthen measles surveillance and implement supplementary immunization programs with measles-containing vaccines for at-risk populations.

ABSTRACT

OBJECTIVE To establish t he method for determining the concentrations of fluoxetine ,norfluoxetine and sertraline in human placental perfusate method and their placental permeability. METHODS Using glyburide as internal standard ,the samples were pretreated by protein precipitation method and detected by ultra-fast liquid chromatograph-mass spectrometer/mass spectrometer (UFLC-MS/MS). The determination was performed on Synergi TM Hydro-RP 80A LC column with mobile phase consisted of water (containing 0.1% formic acid )-acetonitrile(containing 0.1% formic acid )at the flow rate of 0.70 mL/min,with a gradient elution. The column temperature was set at 40 ℃,and sample size was 5 μL. Detection was performed with electrospray ionization source in multipl e reaction monitoring mode . The ion pairs for quantitative analysis we re m/z 309.9→148.1(fluoxetine),m/z 296.0→134.4 (-167), (norfluoxetine),m/z 306.1→159.0 (sertraline),m/z 493.9→ No.2018FE001(-207),(internal standard ). The perfusion model of singal placenta under bidrectional cardiopulmonary bypass was established. Fluoxetine (160 ng/mL),norfluoxetine(160 ng/mL), sertraline(100 ng/mL)and antipyrine (positive control ,ng/mL)were added into the maternal perfusate. The concen- 65324888 trations of fluoxe tine, norfluoxetine and sertrali ne were measured by above UFLC-MS/MS at 0,10,20,30,45,60,90,120,150 and 180 min of circulation ,and the placental permeability was calculated. RESULTS The linear range of fluoxetine ,norfluoxetine and sertraline were 5.00-500 ng/mL(all r> 0.990),and the lower limits of quantification were all 5.00 ng/mL. The RSDs of intra-day and inter-day were all less than 14.0%, and relative error ranged -9.6% to 14.7%. The relative error of stability test was -4.0% to 11.0%;the residual effect ,extraction method and matrix effect did not affect the quantitative analysis of the substance to be tested. Totally 31 perfusion model of human placenta under cardiopulmonary bypass were successfully established ,including 15 fluoxetine and norfluoxetine perfusion ,10 sertraline perfusion and 6 antipyrine perfusion. After 3 hours of perfusion ,the average placental permeability of fluoxetine , norfluoxetine and sertraline were (8.74 ± 1.67)% ,(10.70 ± 4.81)% ,(5.90 ± 1.25)% ,respectively. CONCLUSIONS The established UPLC-MS/MS is simple ,sensitive and accurate. It can be used for determination of fluoxetine ,norfluoxetine and sertraline in human placental perfusate. Fluoxetine ,norfluoxetine and sertraline can pass through the placenta ,but sertraline has a lower placental permeability.

ABSTRACT

Objective To investigate measles antibody levels in healthy people in Jinshan District and their willingness to inoculate measles containing vaccines, and to explore the feasibility of supplementary immunization with adult measles vaccine. Methods People from 4 randomly selected community health service centers were enrolled and divided into groups of 15-19, 20-29, 30-39, and 40 years old and above. Serum was collected for measles antibody level detection and analysis according to the city and foreign household registration. In addition, a questionnaire survey on measles knowledge and vaccination willingness was conducted. Results Of the 234 participants for serum testing, the overall positive rate of measles antibodies (IgG) was 85.47%, and the protection rate was 35.47%. The difference in the positive rate of antibodies in different age groups was statistically significant (χ2=9.78, P=0.02), and the difference in the protection rate was also statistically significant (χ2=14.97, P<0.0012). The positive rate and protection rate were lowest in the group of 20-29 years old, which were 74.19% and 24.19%, respectively. A total of 490 questionnaires were sent out, and 477 questionnaires were effectively returned. Among the 5 questions about measles knowledge, the lowest correct rate was for the transmission route of measles, which was only 48.64%. The willingness to measles vaccination was 85.12%. Multivariate analysis showed that the willingness to vaccination was related to the level of awareness and health education. Conclusion The level of protective antibodies against measles was low in adults in Jinshan District. Health education on measles was insufficient. It is necessary to conduct measles health publicity in institutions with more concentrated personnel. In addition, appropriate measles serological monitoring and supplementary immunization should be carried out for key populations to increase the level of measles antibodies.

ABSTRACT

Objective:To investigate the efficacy and safety of adrenocorticotropic hormone (ACTH) in treating primary nephrotic syndrome in children with dual resistance to glucocorticoids and calcineurin inhibitors (CNIs).Methods:Clinical data of 6 children with primary nephrotic syndrome treated with ACTH in the Children's Hospital of Zhejiang University School of Medicine from January 1, 2015 to December 31, 2019 were retrospectively collected. All the enrolled patients were children with primary nephrotic syndrome with dual resistance to glucocorticoids and CNIs. All the 6 children were given 0.4-1.0 IU·kg -1·d -1 ACTH (total ≤25 IU)+5% glucose 500 ml intravenous infusion for 8 h during the hormone reduction process, with a course of treatment for 5 days, once a month, and continuous treatment for 3-6 months. Clinical data such as 24 h urinary protein quantification, serum albumin, serum cholesterol, estimated glomerular filtration rate (eGFR) level and glucocorticoid dosage were collected at equal time points at 6 months before treatment, at the beginning of treatment, at the end of treatment and at 6 months of follow-up after treatment of ACTH to evaluate the efficacy and adverse reactions. Results:The onset age of 6 children was (4.89±1.77) years, and the age of the first treatment with ACTH was (9.49±3.06) years. All the 6 children completed 3 to 6 months of ACTH treatment, with 2 cases of complete remission, 2 cases of partial remission and 2 cases of no remission. At the end of ACTH treatment, 24 h urinary protein was significantly decreased ( P=0.026), serum albumin level was significantly increased ( P=0.003), and glucocorticoid dosage was significantly decreased ( P<0.001) than before treatment. At 6 months after the end of ACTH treatment, there was no statistical significance in 24 h urinary protein, serum albumin and hormone dosage compared with the end of ACTH treatment (all P>0.05), and the blood cholesterol level continued to decrease ( P=0.039). There was no significant change in eGFR during observation period ( P>0.05). In the process of ACTH infusion, all the 6 children showed transient decrease in urine output, rash in 2 cases, and elevated blood glucose in 1 case, which could be spontaneously relieved after drug withdrawal. There were no serious cardiovascular events, renal impairment, infection and other adverse reactions. Conclusions:ACTH has a good effect on children with primary nephrotic syndrome who are dual resistant to glucocorticoids and CNIs. ACTH can reduce proteinuria, decrease the dosage of glucocorticoids, improve the clinical remission rate, and has good security.

ABSTRACT

Objective:To analyze the consistency and repeatability for quantitative evaluation of normal fetal posterior fossa anatomy using transabdominal three-dimensional ultrasound, and assess the clinical value.Methods:The midsagittal planes of fetal brain from 127 normal singleton fetuses with 22-34 weeks of gestation were obtained using transabdominal three-dimensional ultrasound between May, 2020 and May, 2021. The quantitative three-dimensional indicators were measured by two observers, then were measured twice by one of the two observers. The double blind was performed in course of measuring procedures. The intraobserver and interobserver agreements were evaluated. The relationships between three-dimensional indicators and gestational age were analyzed.Results:The quantitative three-dimensional indicators expressing the size of vermis, including area, perimeter, suprainferior diameter and anteroposterior diameter, had positive correlations with advanced gestational age ( r=0.934, 0.936, 0.920, 0.879; all P<0.001). The intra- and interobserver reproducibilities of measurements were very good with all intraclass correlation coefficients >0.80 (all P<0.001). Brainstem-vermis (BV) angle and Brainstem-tentorium (BT) angle had negative and positive correlations with advanced gestational age respectively ( r=-0.317, 0.366; both P<0.001). The intra-and interobserver reproducibilities of measurements were moderate or poor. Conclusions:The quantitative three-dimensional indicators describing the size of vermis are worthy of clinical application for evaluation of fetal posterior fossa owing to the excellent reproducibility and simple and feasible method of measurement. BV angle and BT angle are not applicable for junior physicians due to the poor reproducibility of measurement.

ABSTRACT

OBJECTIVE:To study the effects of virus in activation treatment of plasma specimen on plasma concentration determination of voriconzole ,linezolid,vancomycin and teicoplanin. METHODS :The remaining plasma of 36 inpatients in our hospital after routine blood concentration examination of voriconazole ,linezolid,vancomycin and teicoplanin were collected as specimen(9 drug-contained plasma specimens for each drug ),and merged into three different concentration levels (low,medium, high)of mixed samples according the results of routine blood test. Then the mixed samples with different concentration levels were divided into inactivated group and non-inactivated group ,with 3 samples in each group. The inactivated plasma samples were heated at 56 ℃ for 30 min in metal bath with constant temperature. Non-inactivated group were not treated. After pretreating plasma sample of 2 groups,2-dimensional liquid chromatography was used to detect plasma concentration of the four drugs ;the difference of detection result between inactivated group and non-inactivated group were analyzed. RESULTS :Plasma samples containing voriconazole,linezolid,vancomycin and teicoplanin were still stable after heating at 56 ℃ for 30 min in metal bath with constant temperature. Compared with non-inactivated group ,relative error of plasma concentration detection result of above 4 drugs were all lower than 15% in low ,medium,high concentration mixed samples of inactivated group. CONCLUSIONS :Plasma samples can be inactivated by heating at 56 ℃ for 30 min in metal bath with constant temperature ,when the plasma concentration of voriconazole,linezolid,vancomycin and teicoplanin are determined by 2-dimensional liquid chromatography.

ABSTRACT

Objective:To investigate the clinical features of patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis misdiagnosed as mental disorder, improve the early diagnosis rate and reduce misdiagnosis.Methods:The clinical data of patients with anti-NMDA receptor encephalitis diagnosed at the First Affiliated Hospital of Zhengzhou University from 2012 to 2018 were collected. Patients misdiagnosed as mental disorders were screened out. Their psychiatric symptom characteristics, disease course characteristics, imaging and laboratory findings, treatment and prognosis were retrospectively analyzed.Results:A total of 121 cases of anti-NMDA receptor encephalitis were collected, and 43 cases of mental disorders were screened out. Sixteen of the 43 patients (37.2%) had prodromal symptoms, and all the patients had psychiatric behavioral abnormalities (100%), including 32 cases (74.4%) of seizures, 13 cases (30.2%) of decreased level of consciousness, 21 cases (48.8%) of involuntary movements, 15 cases (34.9%) of decreased memory, 8 cases (18.6%) of speech dysfunction, and 8 cases (18.6%) of other neurological symptoms (central hyperventilation, autonomic dysfunction). Memory loss was observed in 15 cases (34.9%), speech dysfunction in 8 cases (18.6%), other neurological symptoms (central hypoventilation, autonomic dysfunction) in 8 cases (18.6%), and various symptoms may appear simultaneously or successively in the same patient. Thirty-eight cases had complete resolution of symptoms or only minor physical impairment, and 5 cases had recurrent admissions with mental abnormalities and seizures. The recurrence rate accounted for 11.6% (5/43).Conclusions:The clinical manifestations of anti-NMDA receptor encephalitis are complex and varied. Most of them have mental behavior abnormalities as the first symptom, which is easily misdiagnosed as mental disorder and delayed treatment will lead to prolonged disease course and poor prognosis.

ABSTRACT

Objective:To study the effect of video teaching combined with offline training in cardiopulmonary resuscitation training for new nurses outside hospital.Methods:From August 2017 to August 2018, 125 new nurses from Shanghai Changzheng Hospital were selected. New nurses in August 2017 were set as control group ( n=65). In August 2018, the new nurses were set as the observation group ( n=60). The control group used the traditional offline training mode to train cardiopulmonary resuscitation outside the hospital. The observation group used information platform video teaching combined with offline theoretical training to carry out cardiopulmonary resuscitation training. After systematic training, the results of cardiopulmonary resuscitation after training and the satisfaction of teaching were compared between the two groups. Results:Before training, there was no significant difference in the assessment results of cardiopulmonary resuscitation theory and operation between the two groups ( t values were 0.12, 1.23, P>0.05). After training the scores of cardiopulmonary resuscitation theory and operation examination in the observation group were 85.41±3.20, 92.40±2.50, and 82.52±4.50, 85.0±3.60 in the control group ( t value was 1.04,4.24, all P<0.05). Encouraging and enhancing the learning interest of new nurses, cultivating mutual supervision and mutual guidance, integrating theoretical knowledge with practical operation, improving and adjusting self-motivation, overall evaluation of teaching methods and total score in the observation group were 3.61±0.34, 3.54±0.20, 3.61±0.28, 3.87±0.20, 3.32±0.21, 17.95±0.26, and 2.60±0.41, 2.41±0.16, 2.55±0.35, 2.41±0.46, 2.58±0.20,12.55±0.32 in the control group ( t value was 2.187-2.452, P<0.05). Conclusion:Video teaching combined with offline training can improve the performance of new nurses in the training of high-quality cardiopulmonary resuscitation, stimulate the learning interest of nurses, and enhance the effect of high-quality cardiopulmonary resuscitation training.

ABSTRACT

Objective:This study aimed to evaluate the neuroprotective effect of Buyang-Huanwu Decoction (BYHWD) against cerebral ischemia by using magnetic T2WI and DTI to observe the infarct volume, formation of cerebral edema and injury of white matter fibers on cerebral ischemic rats. Methods:Rat model of cerebral ischemia was established by middle cerebral artery occlusion (MCAO). The successfullly modeled rats were randomly divided into model group and BYHWD group, with 5 rats in each group, and the other 5 rats were taken as sham operation group. The Rats were intragastrically administrated with BYHWD (16.1 g/kg) once daily for 30 d after MCAO. T2WI and DTI examinations were performed on the 3rd, 7th, 14th, 30th day after the surgery.Results:T2WI showed abnormal hyperintensities in the right hemisphere of the MCAO rats on the 3rd, 7th, 14th, 30th day after the surgery. The infarction percentage reduced with time coursing ( P<0.05). Compared with the model group, the rats treated with BYHWD showed reduced infarction percentage [3 d: (13.9% ± 13.7% vs. 40.1% ± 10.7%); 7 d: (13.9% ± 11.9% vs. 28.2% ± 7.7%); 14 d: (10.2% ± 7.9% vs. 24.5% ± 3.5%); 30d: (6.8% ± 6.5% vs. 24.7% ± 8.7%)] ( P<0.05 or P<0.01). The percentage of edema reached the peak on the 3rd day after MCAO. Due to the cerebral atrophy on 30th day, the percentage of edema exhibited negative growth. The edema percentage of BYHWD group reduced significantly on the 3rd and 7th day compared with model group [3 d: (11.4% ± 6.9% vs. 21.5% ± 3.1%); 7 d: (5.5% ± 3.1% vs. 8.7% ± 1.2%)] ( P<0.05 or P<0.01). DTI showed that the low signals indicating fiber injuries were observed in the infarct areas of the model group rats on the 3rd, 7th, 14th, 30th day after MCAO. The rFA values in the ipsilateral cortex and striatum of MCAO rats were significantly decreased compared with the sham group ( P<0.05 or P<0.01). The rFA values in cortex and striatum in focal cerebral ischemia rats of BYHWD group were higher than those in the model group, while only 14 d showed significance ( P<0.05 or P<0.01). Conclusions:T2WI and DTI clearly provided the informations of the location and morphology of the infarct areas. The ischemic brain showed significant infarction, edema, and white matter injury, which were ameliorated with time going on. BYHWD reduced the infarction percentage, inhibited cerebral edema and stimulated the recovery of neurofibra, suggesting that BYHWD could protect against cerebral ischemia.

ABSTRACT

Objective To evaluate the vaccination of live attenuated varicella vaccine ((VarV) in Jinshan District of Shanghai. Methods Descriptive and analytical epidemiological analysis was carried out using the information of VarV immunization of children born between November 1, 2006 and October 31, 2018 (1-12 years) in the Jinshan District Immunization Program Information System. Results There were 82 584 registered children aged 1-12 years in Jinshan District, and the vaccination rate of VarV at the first dose (VarV1) was 90.95%. The vaccination rate of children in this city was higher than that of migrant children, and the annual vaccination rate of children born in different years was between 59.81% and 99.93%. The vaccination rates in northern, central and southern Jinshan District were 89.25%, 93.27% and 91.39%, respectively. Among the 82 584 registered children, the second dose of VarV (VarV2) vaccination rate was 49.01%. The vaccination rate of children in this city was higher than that of migrant children, and the annual vaccination rate of children born in different years was between 25.94% and 77.14%. The vaccination rates in northern, central and southern Jinshan District were 28.72%, 45.88% and 66.30%, respectively. Conclusion The VarV1 vaccination rate of children aged 1-12 in Jinshan District was higher, but the VarV2 vaccination rate was relatively low. It is necessary to further strengthen publicity in key areas to improve the level of VarV2 vaccination.

ABSTRACT

Objective:To investigate the causes and outcomes in the children who did not immediately receive glucocorticoids therapy after initial diagnosis of primary nephrotic syndrome (PNS).Methods:The clinical data of PNS patients not immediately receiving glucocorticoids therapy after initial diagnosis at the Department of Nephrology, the Children's Hospital, Zhejiang University School of Medicine from January 1, 2005 to December 31, 2014 were retrospectively analyzed.Results:A total of 1 431 cases were initially diagnosed with PNS, including 1 061 males and 370 females. Among them, 130 cases did not receive conventional glucocorticoids treatment immediately, accounting for 9.1%. Of whom, 75 cases were found showing spontaneous remission after symptomatic treatment; 23 cases were directly treated with adrenocorticotropic hormone (ACTH), one case with mycophenolate mofetil (MMF), and 31 cases not given glucocorticoids or immunosuppressants because of parental refusal. Among 75 cases with spontaneous remission, 16 cases were found in sustained remission; 39 cases were treated with glucocorticoids and 6 cases with ACTH at relapse; 14 cases were lost. Among 29 cases using ACTH, 7 cases were found in sustained remission. Among the 31 cases who refused glucocorticoids or immunosuppressants therapy, one died. The case treated with MMF, later were given with halved hormone because of no-effective response.Conclusions:Spontaneous remission is found in a small proportion of PNS patients at first-onset, but most subsequently relapse. Hormone therapy should be routinely given unless remission has occurred before application. Some children's parents refuse hormone therapy, and need further communication. Some cases initially treated with ACTH are found in sustained remission, which should be further observed and studied to clear the efficacy and safety of ACTH.

ABSTRACT

From July to August 2018, a survey on the awareness of diabetic foot screening was conducted using the online questionnaires posted on the WeChat group. From 107 trainees in General Practitioner Teacher Training Program of Beijing Xicheng District and 50 general practitioners working in Chinese Academy of Sciences, 145 valid questionnaires were received. All 145 participants worked in community health care settings, including 105 general practitioners, 76 had 10 to 20 years of service, and 98 had undergraduate degree. The survey showed that 75.9% (110/145) heard the diabetic foot screening and knew that screening should be done for all diabetic patients; 98.6% (142/145) knew that the screening should include medical history, foot skin, neuropathy, vascular status, and 73.1% (106/145) also knew that screening should include the foot bone, joint deformities and footwear selection; 21.4% (31/145) had participated in training related to diabetic foot screening. It is suggested that the awareness and knowledge of diabetic foot screening among Beijing community medical personnelare not sufficient, and more training opportunity is necessary for them.

ABSTRACT

Objective:To evaluate the placental villus blood flow in different pregnancy using superb microvascular imaging(SMI).Methods:Fifty single pregnant women were randomly selected from early pregnancy pregnant women with outpatient examinations from January 2019 to June 2019. The SMI technique was used to monitor the villus blood flow of the placenta during routine ultrasound examination in early, middle and late pregnancy. The blood flow of the placental villus at the insertion point of the placenta umbilical cord and the edge of the placenta was explored, and the corresponding arterial blood flow spectrum was collected, and the values of systolic/diastolic velocity ratio(S/D), pulsatility index(PI), resistance index(RI) and peak systolic velocity(PSV) were recorded. The correlation between the measurement rate of villus blood flow spectrum and the placenta position, fetal position, and pregnancy period were analyzed by Spearman correlation. Chi-square test was used compare the difference of the display rates of placental villus blood flow and the measurement rates of blood flow spectrum during different pregnancy periods. The consistency analysis of the results between the two inspectors was performed using Kappa test.Results:Finally, 30 pregnant women were enrolled. SMI showed 98.9% (89/90) of placental villus blood flow. The consistency of the examination results between the two examiners was good. The measurement rate of villus artery blood flow spectrum was not correlated with the placenta and fetal position ( P>0.05), but correlated with defferent trimesters ( r s=0.478, P<0.05). There was no difference in the display rate of villus blood flow at the insertion point of the placenta umbilical cord and at the edge of the placenta in each trimester( P>0.05). The measurement rate of blood flow spectrum was statistically different ( P<0.05). And the measurement rate of early pregnancy (33.3%/3.3%) was lower than the middle (70.0%/50.0%) and late pregnancy (56.6%/60.0%). The consistency of the examiners results between the two examiner is good (Kappa=0.55-0.92, P<0.05). Conclusions:SMI can display the blood flow of placental villus in different stages of pregnancy and can measured blood flow accordingly. The different pregnancy stages affect the measurement results. Placental villus blood flow measurement in the middle and late pregnancy is easier to measure than in the early pregnancy. The fetal position and placental position do not affect blood flow measurement.

ABSTRACT

Objective:To explore the value of contrast-enhanced ultrasound(CEUS) in distinguishing of renal oncocytoma(RO) and chromophobe renal cell carcinoma(chRCC).Methods:The ultrasonic image features of 49 ROs and 72 chRCCs between October 2007 and January 2020 were retrospectively analyzed, all lesions underwent ultrasonic examination (including 19 ROs and 70 chRCCs with CEUS imaging) and were pathologically approved in our institution. The statistically significant parameters from univariate analyses were then entered for further multivariable Logistic regression. The value of each ultrasonic imaging feature in differentiating RO and chRCC was evaluated.Results:According to the univariate analyses, all imaging features on conventional ultrasound were not statistically different between RO and chRCC (all P>0.05), while the characteristics of tumor wash-in/out pattern, enhancement degree and homogeneity at peak time and pseudocapsule around tumor were significantly different (all P<0.05). After multivariable analyses, tumor wash-in and wash-out pattern were excluded for tumor differentiation ( P>0.05), and the parameters of enhancement degree or homogeneity at peak time and pseudocapsule around tumor were still significantly different between tumor types (all P<0.05, odd ratio was 8.683, 6.667 and 18.774 respectively). The overall sensitivity, specificity and accuracy of these three parameters in diagnosing RO was 68.4%, 91.4% and 86.5%, respectively.

ABSTRACT

Objective:To measure the choroidal thickness (CT) in the macular area of patients with amblyopia in severe congenital ptosis and to compare the thickness with that of severe congenital ptosis without amblyopia.Methods:A cross-sectional study was performed.Total of 83 eyes of 60 severe congenital ptosis patients were enrolled from January to October in the year 2019 in the Shanxi Eye Hospital, including 29 patients 37 eyes with amblyopia and 36 patients 46 eyes without amblyopia.Thirty-seven eyes of 37 normal people were included in the control group.All subjects underwent mydriatic optometry and the spherical equivalent (SE) was calculated.IOL-Master was used to measure the axial length (AL), and EDI-OCT was used to measure the CT in the macular area.The CT was measured at 13 points: directly beneath the fovea (SFCT) and at 1 mm, 2 mm and 3 mm intervals to the nasal, temporal, superior and inferior to the fovea.The points of CT measurements were named according to their positions and distances relative to the fovea, and represented by SFCT, N1, N2, N3, T1, T2, T3, S1, S2, S3, I1, I2, I3 respectively.The SE, absolute astigmatism degree, AL and CT at each point were compared among the groups.The corrected AL covariance analysis was used to compare the CT at different measurement points among the groups.Spearman rank correlation analysis was used to evaluate the correlation between CT and AL or SE, and unitary linear regression analysis was used to evaluate the influence of age on AL in each group.This study was approved by the Ethics Committee of Shanxi Eye Hospital.All the subjects signed informed consent.Results:Compared with the non-amblyopia group and control group, the SE and absolute astigmatism value was larger, and the AL was shorter in the amblyopia group (all at P<0.05). The mean SFCT was (388.85±54.85), (301.48±56.68), and (287.08±61.88)μm in the amblyopia group, non-amblyopia group, and control group, respectively.Except for I3, the CT values of the rest parts in the amblyopia group were greater than those in the non-amblyopia group and the control group (all at P<0.05). Except for S3 and I3, the CT values of the rest parts in the amblyopia group were greater than those in the non-amblyopia group and the control group after adjusting the AL ( P<0.05). In all the three groups, the CT value was high in the subfovea and was thin in the nasal side.The SFCT was negatively correlated with AL (amblyopia group: rs=-0.340, P=0.045; non-amblyopia group: rs=-0.340, P=0.020; control group: rs=-0.463, P<0.001) and positively correlated with SE (amblyopia group: rs=0.350, P=0.039; non-amblyopia group: rs=0.412, P=0.004; control group: rs=0.450, P=0.005) in each group.Age was the influencing factor of AL in the non-amblyopia group and the control group ( β=0.243, 0.225; both at P<0.001). Conclusions:In comparison with severe congenital ptosis without amblyopia, the SE and absolute astigmatism degree are larger, the AL is shorter, and the CT values at most areas are higher in the severe congenital ptosis with amblyopia.CT value may be associated with the development of amblyopia in severe congenital ptosis.

ABSTRACT

Objective:To investigate the distribution of the spherical aberration in age-related cataractous eyes using the Pentacam HR.Methods:A cross-sectional study was performed in Shanxi Eye Hospital from December 2014 to December 2015.The preoperative corneal spherical aberration of 1 319 eyes of 1 319 patients with age-related cataract over 40-years-old was analyzed.The mean average keratometry (Km value), and corneal posterior surface Km corneal astigmatism, posterior corneal astigmatism, and corneal thickness were measured with.Pentacam, and the Zernike coefficients of corneal spherical aberration were calculated.A correlation between spherical aberration and corneal parameters was evaluated by Pearson correlation analysis.The proportion of eyes qualifying for spherically neutral or negatively aspheric intraocular lens targeted residual spherical aberration level was evaluated.This study protocol was approved by Ethics Committee of Shanxi Eye Hospital and complied with Declaration of Helsinki.Results:The average age of all patients was (68.00±11.12) years old with an average spherical aberration (0.34±0.17)μm.The spherical aberration was lower than 0 μm in 22 eyes (1.67%), 0~0.4 μm in 842 eyes (63.84%), and greater than 0.4 μm in 455 eyes (34.50%). There was a weak positive correlation between spherical aberration and age ( r=0.398, P<0.001). There were very weak correlations between spherical aberration and corneal Km, posterior corneal surface Km, corneal thickness ( r=0.129, P<0.001; r=0.240, P<0.001; r=-0.068, P<0.05). No significant correlations were found between spherical aberration and corneal astigmatism or posterior corneal astigmatism ( r=-0.025, P=0.365; r=-0.008, P=0.771). Seven hundred and ten eyes (53.83%) could be qualified for implantation of negatively or neutrally aspheric intraocular lens based on postoperative targets of (0.10±0.05)μm residual spherical aberration. Conclusions:Corneal spherical aberration in Chinese patients is greater than that in other populations (+ 0.27 μm) in literature and shows individual differences.The appropriate aspheric intraocular lens should be selected according to individual corneal spherical aberration before cataract operation.

ABSTRACT

Objective:To investigate the effect of risk management in perioperative nursing of a patient undergoing total hip and knee replacement.Methods:The risk management method was used to identify, assess, nurse and evaluate the perioperative complications,such as hypertension, dislocation of hip prosthesis, gastroparesis and others of patients with total hip and knee replacement.Results:The nursing risks of the patient were accurately identified and effectively controlled, which ensured the safety and the smooth discharge of the patient. The perioperative blood pressure was controlled at about 150/80 mmHg (1 mmHg=0.133 kPa) . After operation, the position of the prosthesis was satisfied, patient could walk with the help of walker, the symptoms of gastroparetosis was alleviated, so that patient could eat well.At the time of discharge, the patient ′s albumin was 38 g/L, hemoglobin was 130 g/L and electrolyte levels were normal. The level of anxiety was alleviated, with the anxiety score dropping from 71 to 49, which means a mild level of anxiety. Conclusion:The perioperative nursing of elderly patients undergoing total hip and knee replacement surgery is difficult, and multiple risks co-exist. Clinical nurses should identify and manage the symptoms of high-risk patients early, accurately and effectively, so as to improve the nursing quality and ensure the safety of patients.
