To summarize the nursing experience of hematopoietic stem cell transplantation for a child with monocytopenia and mycobacterium infection syndrome complicated with pulmonary alveolar proteinosis.The key aspects of nursing encompass the establishment of a multidisciplinary diagnostic and treatment team,as well as the enhancement of warehousing preparation.Fine nursing plays a pivotal role in infection prevention and control,while also promoting hematopoietic reconstruction.Vigilant monitoring of condition changes is crucial to proactively prevent cardiopulmonary failure.Moreover,an intensified management approach towards underlying diseases should be implemented alongside predictive nursing interventions.The utilization of precision medication plans allows for the observation of drug efficacy and adverse reactions.Narrative nursing serves as a foundation to alleviate the child's inner concems,while personalized follow-up plans ensure the continuity of high-quality care.With careful treatment and care,the child successfully underwent hematopoietic stem cell transplantation.After 41 days post-transplantation,the child was discharged from the hospital after a successful recovery.The follow-up after a month showed good progress.

Objective:To retrospectively analyze the prognosis and related risk factors of lymph node metastasis in early-stage (Ⅰ B-Ⅱ A) cervical cancer patients with postoperative positive lymph nodes who were treated with intensity modulated radiotherapy (IMRT). Methods:A retrospective analysis was conducted for 292 early-stage cervical cancer patients with postoperative high and/or moderate risk factors who were treated with pelvic-abdominal IMRT with/without concurrent chemotherapy in Ningxia Medical University General Hospital from January 2016 to December 2018. These patients included 239 with negative pelvic lymph nodes and 53 with positive lymph nodes, who were incorporated into the negative group and the positive group, respectively. Multivariate and univariate analyses of the risk factors of lymph node metastasis and prognosis were performed for both groups.Results:The univariate and multivariate analyses showed that the lesion ≥4 cm, deep interstitial invasion, and the number of risk factors were independent factors influencing pelvic lymph node metastasis ( χ2 = 7.11, 9.05, 90.08, P < 0.05). There was no statistically significant difference in the 3- and 5-year OS ( P>0.05) between both groups. The 3-year disease-free survival (DFS) and 5-year DFS of the negative group were 87.6% and 84.5%, respectively, and those of the positive group were 72.5% and 69.3%, respectively ( χ2=8.59, P=0.003). Regarding failure modes, distant metastasis mainly occurred in the positive group, while local recurrence was dominant in the negative group ( χ2=9.40, P<0.05). The univariate analysis of the DFS in 53 patients with postoperative positive lymph nodes showed that deep interstitial invasion affected DFS, with statistically significant differences ( χ2 = 7.25, P < 0.05). The result of the multivariate analysis showed that the lesion size >4 cm, positive residual, and deep interstitial invasion significantly influenced the DFS ( χ2 = 4.37, 4.69, 4.39, P < 0.05). Conclusions:The lesion size, deep interstitial invasion, and risk factor number were independent factors influencing lymph node metastasis, and the DFS after radiotherapy of patients with pelvic lymph node metastasis was significantly lower than the patients with negative lymph nodes. The main recurrence type of patients with lymph node metastasis was distant metastasis. Moreover, the deep interstitial invasion was independent factor affecting the DFS of early-stage cervical cancer patients with postoperative positive lymph nodes.

Objective:To retrospectively analyze the differences of survival, recurrence, acute side effects and prognostic factors between early stage (stage ⅠB-ⅡA) cervical cancer patients with intermediate risk factors receiving postoperative concurrent chemoradiotherapy (CCRT) or radiotherapy (RT) alone.Methods:Clinical data of 211 patients with intermediate risk factors after early stage cervical cancer surgery admitted to Department of Radiation Oncology of General Hospital of Ningxia Medical University from January 2016 to December 2018, were retrospectively analyzed. Among them, 91 cases were assigned in the RT group and 120 cases in CCRT group. The 3- and 5-year overall survival (OS), progression-free survival (PFS), recurrence and acute side effects were compared between two groups by Chi-square test. Univariate analysis of OS and PFS was performed by Kaplan-Meier method and log-rank test was performed. Multivariate prognostic analysis was conducted by using Cox model. Results:The 3- and 5-year OS of 211 patients were 95.0% and 93.8%, respectively. The 3- and 5-year PFS were 86.8% and 83.2%, respectively. The OS of CCRT and RT group were 93.9%, 96.5% (3-year), 91.8%, 96.5% (5-year) respectively ( χ2=1.763, P=0.184), and the PFS were 84.4%, 89.9% (3-year), 79.3%, 88.3% (5-year) ( χ2=2.619 ,P=0.106), with no difference between the two groups. The total recurrence rate was 15.64%, and there was no significant difference in the recurrence rate and recurrence area between two groups ( χ2=2.623 ,P=0.105; χ2=6.745 ,P=0.080). Locoregional recurrence and lung metastasis were the main patterns of failure. Multivariate prognostic analysis showed that pathological type might significantly affect the OS ( χ2=3.849, P=0.05), and depth of invasion significantly affected the PFS ( χ2=4.095, P=0.043). The incidence of acute gastrointestinal side effect and bone marrow suppression in the CCRT group was significantly higher than that in the RT group ( χ2=56.425, 27.833; both P<0.001). Conclusions:Patients with intermediate risk factors after early cervical cancer surgery obtain high efficacy after radiotherapy. The main patterns of failure are locoregional recurrence and lung metastasis. The pathological type may be an independent prognostic factor of OS and the depth of invasion is an independent prognostic factor of PFS. Compared with RT, CCRT increases the risk of acute gastrointestinal side effects and myelosuppression, which can be tolerated. There is no significant difference in the clinical efficacy between RT and CCRT, which remains to be validated by large sample size studies.

Objective:The epidemiological characteristics of PICU deaths in 2017 in the Affiliated Hospital of Guizhou Medical University, Guizhou Provincial People′s Hospital, and Guiyang Children′s Hospital were summarized and analyzed to provide a basis for formulating intervention measures to effectively reduce the mortality rate of children.Methods:The clinical datas of PICU deaths in three tertiary hospitals in 2017 were collected retrospectively.The cases were divided according to different ages and lengths of hospitalization.And gender, age, length of death, length of hospitalization, and death diseases were summarized and analyzed.Results:In 2017, the PICU of the three tertiary hospitals admitted 2 092 children, of which 139 (6.64%) died, including 84 males and 55 females.The months with the highest case fatality rates were January, February, July and August.The fatality rates were 9.14% (18/197), 9.04% (15/166), 13.25% (20/151), 7.93% (13/164), respectively.There was statistically significant difference in the mortality of children admitted in each month ( P=0.038). Among the death cases, the infant group (29 days to 1 year old) accounted for the largest proportion with 58 cases (41.73%), followed by the preschool group (3 to 7 years old) with 37 cases (26.62%), the infant group (1 to 3 years old) with 24 cases(17.27%), and the school-age group (7 to 14 years old) with 20 cases(14.38%). The top three death diseases were: 39 cases (28.06%) of bronchial pneumonia (severe), 28 cases (20.14%) of hematological tumors and solid tumors, and 23 cases (16.55%) of trauma.The difference of its distribution in different age groups was statistically significant( P<0.05). The patients were divided into four groups according to the length of hospital stay.The time ≤1 d group had the highest mortality of 54 cases (38.85%), -3 d group and -7 d group both had 32 cases (23.02%), the >7 d group had the lowest mortality of 21 cases (15.11%). Conclusion:In 2017, January, February and July, August are the peak months of deaths in PICUs in Guizhou, with the highest number of infant deaths.Bronchial pneumonia(severe), hematological tumors and solid tumors, and trauma are the top three death diseases.

Objective:To investigate the efficacy of free thin sensate superficial circumflex iliac artery perforator flap based on lateral cutaneous branch of the subcostal nerve for repair of soft tissue defect in the foot and ankle.Methods:A retrospective case series study was made on clinical data of 9 patients with soft tissue defect in the foot and ankle admitted to 80th Group Military Hospital from December 2017 to December 2019. There were 8 males and 1 females, with the age of 28-63 years [(47.3±12.3)years] and the body mass index (BMI) of 16.7-27.8 kg/m 2 [(23.9±3.9)kg/m 2]. The size of soft tissue defect ranged from 10 cm×6 cm to 20 cm×12 cm. All patients were treated with the free thin sensate superficial circumflex iliac artery perforator flap based on lateral cutaneous branch of the subcostal nerve. After debridement or tumor resection, a thin sensate flap was harvested by intra-adipose tissue dissection between the superficial and deep fat layers. The size of flap ranged from 13 cm×8 cm and 13 cm×10 cm. The thickness of the defatted flap ranged from 3-6 mm. The distance from the anterosuperior iliac spine to the point where the lateral cutaneous branch of the subcostal nerve crossed the iliac crest ranged from 7.5-10.0 cm. The flap survival, complications, and reoperation were observed after operation. The sensory recovery of the flap was evaluated using Tinel sign and nine-grid method including monofilament touch perception, vibration perception, pinprick perception, temperature perception, and static two-point discrimination test. The joint range of motion, and shoewear and walking problems were recorded. At the last follow-up, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used to assess the affected foot and ankle. The injury at the donor site was detected as well. Results:All patients were followed up for 6-35 months [(21.1±10.1)months]. All flaps survived without infection or tumor reoccurrence. One patient developed ulceration, then surplus skin on the reconstructed heel was resected. One patient underwent flap debulking and removal of internal fixation. One or more sensory modalities within the nine areas in each flap could be detected at postoperative 3-6 months. The monofilament touch, vibration, pinprick, and temperature perception were presented in almost all regions of each flap at postoperative 12 months. However, only one patient in one region was noted with the static two-point discrimination, in which the distance of the two points was set as 25 mm. The range of ankle motion was slightly limited in 2 patients who underwent osseoligamentous complex reconstruction. All patients were able to wear normal shoes and walk without pain. At the last follow-up, the AOFAS ankle-hindfoot score ranged from 78 to 97 points [(86.4±7.4)points], significantly improved from preoperative 10-70 points [(44.2±18.4)points] ( P<0.01). No patients complained of pain at the donor site, but the widening linear scar was noted. Conclusion:For medium-sized soft tissue defect of the foot and ankle, the free thin sensate superficial circumflex iliac artery perforator flap based on lateral cutaneous branch of the subcostal nerve can be defatted with the requirement and has advantages in defect site appearance, sensory restoration, wearing ordinary shoes, painless walking, good functional recovery, and minimal donor site morbidity.

Objective:To analyze the feasibility of applying transcutaneous electrical nerve stimulator and high-frequency ultrasound in superficial nerve positioning for detection anatomical location in the area of lateral lip of the iliac crest by lateral cutaneous branch of subcostal nerve(LCSN). The significance of using the nerve as a free sensory superficial circumflex iliac artery perforator flap was discussed.Methods:The data of patients who underwent the repair of defects on limbs with free perforator flap or composite flap of superficial iliac circumflex artery carrying sensory nerve and the volunteers who agreed to have the location of the LCSN measured between October, 2018 and October, 2020 were collected. The LCSN were located by percutaneous electrical nerve stimulation and ultrasound, and the patients were measured and located during surgery. Using Passing-Bablok regression and Bland-Altman graph to evaluated the consistency between transcutaneous electrical nerve stimulation, ultrasound and the surgical positioning.Results:A total of 43 subjects, including 22 patients and 21 volunteers, were selected for locating the LCSN. Thirty-nine males and 4 females, with an average age of 39 years old and an average BMI of 24.08. The operation time of percutaneous nerve electrical stimulation was(6±1) min, and the detection distance was(80.7±5.9) mm. The high-frequency ultrasound was(23±4) min, and the distance was(81.2± 6.6) mm. The average operation time of surgical measured distance was(80.9±8.2)(65-100) mm, the diameter of nerve was(2.3±0.8)(1.0-4.0) mm, and the operation time was(5±1) min. A 95% CI of Passing-Bablok regression intercept and slope of operation, percutaneous electrical nerve stimulation and ultrasoundincluded 0 and 1, respectively. The points on Bland-Altman plot were distributed on both sides, and 95% CI of total mean difference, total intercept and slope included 0. Therefore, it was can be considered that the application of percutaneous electrical nerve stimulation and ultrasound in LCSN localization has good consistency.Conclusion:The location point of the LCSN crossing the iliac crest which detected by transcutaneous electrical nerve stimulation and high-frequency ultrasound detection was close to the measurement taken during the operation. It was also showed that both of them can be used for preoperative locationing of the sensory branch of the sensory nerve flap, optimizing the design of the flap, shortening the operation time, and reducing the unnecessary injury in operation.

Objective:To investigate the etiology of necrotizing pneumonia (NP) in children and the clinical characteristics of NP caused by different pathogens in China.Methods:A retrospective, case-control study was performed in children with NP who were admitted to 13 hospitals in China from January 2008 to December 2019. The demographic and clinical information, laboratory data, etiological and radiological findings were analyzed. The data were divided into three groups based on the following years: 2008-2011, 2012-2015 and 2016-2019, and the distribution characteristics of the pathogens in different period were compared. Meanwhile, the pathogens of pediatric NP in the southern and northern China were compared. And the clinical characteristics of the Mycoplasma pneumoniae (MP) NP and the bacterial NP were also compared. T-test or Mann-Whitney nonparametric test was used for comparison of numerical variables, and χ 2 test was used for categorical variables. Results:A total of 494 children with NP were enrolled, the median ages were 4.7 (0.1-15.3) years, including 272 boys and 222 girls. Among these patients, pathogens were identified in 347 cases and the pathogen was unclear in the remaining 147 cases. The main pathogens were MP (238 cases), Streptococcus pneumoniae (SP) (61 cases), Staphylococcus aureus (SA) (51 cases), Pseudomonas aeruginosa (13 cases), Haemophilus influenzae (10 cases), adenovirus (10 cases), and influenza virus A (7 cases), respectively. MP was the most common pathogen in all three periods and the proportion increased yearly. The proportion of MP in 2016-2019 was significantly higher than that in 2012-2015 (52.1% (197/378) vs. 36.8% (32/87), χ 2= 6.654, P=0.010), while there was no significant difference in the proportion of MP in 2012-2015 and that in 2008-2011 (36.8% (32/87) vs. 31.0% (9/29), χ2=0.314, P=0.575).Regarding the regional distribution, 342 cases were in the southern China and 152 in the northern China. Also, MP was the most common pathogen in both regions, but the proportion of MP was higher and the proportion of SP was lower in the north than those in the south (60.5% (92/152) vs. 42.7% (146/342), χ 2=13.409, P<0.010; 7.9% (12/152) vs. 14.3% (49/342), χ 2= 4.023, P=0.045). Comparing the clinical characteristics of different pathogens, we found that fever and cough were the common symptoms in both single MP and single bacterial groups, but chest pain was more common (17.0% (34/200) vs. 6.1% (6/98), χ 2=6.697, P=0.010) while shortness of breath and wheezing were less common in MP group (16.0% (32/200) vs. 60.2% (59/98), χ 2=60.688, P<0.01; 4.5% (9/200) vs. 21.4% (21/98), χ 2=20.819, P<0.01, respectively). The white blood cell count, C-reactive protein and procalcitonin in the bacterial group were significantly higher than those in the MP group (14.7 (1.0-67.1)×10 9/L vs. 10.5 (2.5-32.2)×10 9/L, 122.5 (0.5-277.3) mg/L vs. 51.4 (0.5-200.0) g/L, 2.13 (0.05-100.00) μg/L vs. 0.24 (0.01-18.85) μg/L, Z=-3.719, -5.901 and -7.765, all P<0.01). Conclusions:The prevalence of pediatric NP in China shows an increasing trend during the past years. MP, SP and SA are the main pathogens of NP, and the most common clinical symptoms are fever and cough. The WBC count, C-reactive protein and procalcitonin in bacterial NP are significantly higher than those caused by MP.

Objective:To investigate the clinical application of cervix-uterine internal target volume (ITV) in volume-modulated arc therapy (VMAT) for cervical cancer under different bladder filling conditions, aiming to obtain more accurate planning target volume (PTV).Methods:Sixty-two patients with cervical cancer receiving radiotherapy rather than surgery were selected and randomly divided into the study ( n=31) and control groups ( n=31). In the study group, individualized ITV, PTV and PTV margin were obtained under three bladder filling status by localization CT scan to compare the VMAT. The target area and organs at risk (OARs) within the target area were statistically compared between two groups. The target missing rate in CBCT, adverse events and short-term efficacy of radiotherapy were analyzed in two groups. Results:There was no significant difference in the volume of target area and OARs in the target area between two groups (both P>0.05). In the study group, the target missing rate and target missing volume were significantly lower compared with those in the control group (both P<0.05). There was no significant difference in the incidence of acute radiation-induced adverse events between two groups ( P>0.05). The 1-, 2-year overall survival and progress-free survival did not significantly differ between two groups (all P>0.05). One patient in the study group had uterine recurrence and 2 cases in the control group. Conclusion:Application of individualized cervix-uterine ITV and PTV in definitive VMAT under different bladder filling conditions can improve the accuracy of target area contouring and improve the local control rate in cervical cancer patients.

Objective:To analyze the level and trend of low birth weight mortality in children under 1 year old in China from 2004 to 2018.Methods:The published Data Set of National Mortality Surveillance from 2004 to 2018 was used to analyze the low birth weight mortality rate, constituent ratio and changing trend in boys and girls, in urban area and rural area and in different regions in China. The Joinpoint regression model fitted by the weighted least square method was used to analyze the time variation trend and calculate the annual percentage change (APC), the average annual percentage change (AAPC) and their 95 % confidence intervals in each time period. Results:From 2004 to 2018, the low birth weight mortality rate in children under 1 year old in China showed a decreasing trend with an AAPC of -8.0 % (95 %CI: -10.6 % --5.4 %). The differences between boys and girls, between urban area and rural area and among different regions gradually reduced. From 2004 to 2018, the constituent ratio of low birth weight mortality showed an increasing trend with an AAPC of 1.6 % (95 %CI: 0.1 %-3.2 %). The mortality rate in urban area (38.74 per 100 000) was higher than that in rural area (30.44 per 100 000). The annual average declining speed of low birth weight mortality rate in urban area (AAPC=-3.4 %, 95 %CI: -7.0 %-0.3 %) was slower than that in rural area (AAPC=-9.3 %, 95 %CI: -12.0 % --6.6 %). The low birth weight mortality rate of boys (36.25 per 100 000) was higher than that of girls (28.22 per 100 000). The low birth weight mortality constituent ratio in western region showed an increasing trend, its average annual percentage change (AAPC=3.2 %, 95 %CI: 1.7 %-4.8 %) increased faster than that of the eastern region (AAPC=-0.5 %, 95 %CI: -2.3 %-1.4 %). In urban and rural areas and different regions, the rate of low birth weight mortality in boys was higher than that in girls. Conclusions:From 2004 to 2018, the mortality rate of low birth weight in children under 1 year old showed a downward trend, and the constituent ratio showed an upward trend. Boys and children living in central and western regions should be the key population for maternal and child health care.

Objective:To analyze the trend of the congenital heart disease mortality rate in children aged under 1 year old from 2004 to 2018.Methods:The mortality rate and constituent ratio of congenital heart disease in different genders, urban and rural areas and regions were calculated by using the publicly available Dataset of National Mortality Surveillance in China from 2004 to 2018. The Joinpoint regression model was used to analyze the changing trend of mortality rate and constituent ratio, and calculate the annual percentage change (APC) in each time period, the average annual percentage change (AAPC) in all time period and their 95% values.Results:From 2004 to 2018, a total of 15 969 children aged 0 to 1 years died of congenital heart disease, of which 58.12% (9 281) were boys and 71.79% (11 464) were in rural areas. The deaths of congenital heart disease in eastern, central and western regions accounted for 34.30%, 37.06% and 28.64% of total deaths, respectively. From 2004 to 2018, the mortality rate of congenital heart disease in children decreased from 106.81 per 100 000 to 38.70 per 100 000, with an AAPC (95%) about -7.2% (-11.5%, -2.6%). The mortality rate of congenital heart disease showed a downward trend in girls [AAPC (95%) =-7.7% (-13.0%, -2.0%)], boys [AAPC (95%)=-6.8% (-12.0%, -1.2%)], urban areas [AAPC (95%) =-5.9% (-9.9%, -1.7%)], rural areas [AAPC (95%) =-7.4% (-10.5%, -4.2%)], eastern region [AAPC (95%)=-8.6% (-14.2%, -2.6%)], and central region [AAPC (95%)=-7.8% (-11.5%, -4.0%)]. The gaps of mortality rate gradually shrank in different genders, urban and rural areas and regions. From 2004 to 2018, the constituent ratio of congenital heart disease in children showed an upward trend [AAPC (95%) = 3.3% (1.7%, 4.9%)].Conclusion:From 2004 to 2018, the mortality rate of congenital heart disease in children aged 0 to 1 years showed a downward trend, and the constituent ratio showed an upward trend.
