Objective:To explore the effect of whole-process management mode based on "Internet + nursing service" in the management of children with concealed penis.Methods:This study adopted a quasi-experimental research method. A total of 383 children with concealed penis who were hospitalized in the Third Department of Urology of Hunan Provincial People′s Hospital from January 2018 to August 2021 were convenient selected. According to the sequence of admission, 195 children admitted from January 2018 to May 2020 were set as the control group, and 188 children admitted from June 2020 to August 2021 were set as the observation group. The control group was received conventional treatment and nursing, but the observation group was received whole-process management mode based on "Internet + nursing service". The length of hospitalization, incidence of complications after discharge, anxiety of the children′s parents and satisfaction of the doctors, the specialist & nurse sharing and the children′s parents were compared between the two groups.Results:Finally, 186 and 193 children were included in the observation group and the control group, respectively After the intervention, in the observation group, the length of hospitalization, anxiety score of the children′s parents, difference of anxiety score of the children′s parents, satisfaction content of the doctors, satisfaction effect of the doctors, satisfaction content of the specialist & nurse sharing, satisfaction effect of the specialist & nurse sharing, satisfaction content of the children′s parents and satisfaction effect of the children′s parents were (4.30 ± 1.35) d, (35.08 ± 3.17) points, (19.14 ± 4.35) points,(4.57 ± 0.54) points, (4.71 ± 0.49) points, (4.75 ± 0.50) points, (5.00 ± 0.00) points, (4.60 ± 0.49) points, (4.65 ± 0.49) points; in the control group, the scores were (5.50 ± 1.41) d, (44.79 ± 3.30) points, (9.22 ± 3.67) points, (3.71 ± 0.49) points, (4.00 ± 0.58) points, (3.50 ± 0.58) points, (3.25 ± 0.50) points, (3.54 ± 0.59) points, (3.64 ± 0.67) points. The differences between the two groups were statistically significant ( t values were -23.94-29.19, all P<0.05). The complication rates of the observation group and the control group were not statistically significant ( χ2=0.64, P>0.05). Conclusions:The whole-process management mode based on "Internet + nursing service" is beneficial to shorten the length of hospitalization, relieve the degree to anxiety of the children′s parents, improve the satisfaction of the doctors, the specialist & nurse sharing and the children′s parents, and accelerate the rehabilitation of children, which is worthy of clinical promotion.

Objective Apply modified bilateral carotid artery ligation to establish a VD rat model to observe changes in cerebral blood flow and expression of angiogenic proteins.Methods Thirty-six SD male rats were randomly divided into a sham group(n = 18)and model group(n = 18).In the sham group,only the bilateral carotid artery was isolated without ligation,whereas in the model group,the bilateral carotid artery was ligated to establish the VD model.The Morris water maze behavior test was applied before and 14 days after modeling.Variation in cerebral blood flow was detected by laser speckle contrast imaging.Protein expression of HIF-1α,VEGF,and HO-1 was detected by Western Blot.IL-4 and IL-10 contents were measured by ELISA.Results At 14 days after modeling,escape latency was significantly prolonged and the frequency of crossing the platform had significantly decreased in the model group compared with the sham group(P<0.05).At 2 hours,3 days,and 7 days after modeling,cerebral blood flow in the model group was significantly lower than that in the sham group(P<0.05).At 14 and 21 days after modeling,no significant difference was found in cerebral blood flow between sham and model groups(P>0.05).In the model group,cerebral blood flow was decreased to a minimum at 2 hours after modeling(P<0.05)and then began to recover.The peak of recovery occurred at 3～7 days after modeling and returned to the level before modeling on day 14 after modeling.At postoperative day 21,expression of HIF-1α,VEGF,and HO-1 proteins in the hippocampus of the model group was increased remarkably(P<0.05)and the serum contents of IL-4 and IL-10 in the model group were significantly increased compared with those in the sham group(P<0.05).Conclusions The variation in cerebral blood flow in the VD rat model established by the modified bilateral carotid artery ligation was dependent on time.At postoperative day 21,HIF-1α,VEGF,and HO-1 in the hippocampus were increased significantly,which was accompanied by increased levels of IL-4 and IL-10.

BACKGROUND: Postoperative complications are an important cause of death after lung resection. At present, the adoption of video assisted thoracoscopic surgery (VATS) for lung cancer in China is increasing every year, but the prediction model of postoperative complications of VATS for lung cancer is still lack of evidence based on large sample database. In this study, Thoracic Mortality and Morbidity (TM&M) classification system was used to comprehensively describe the postoperative complications of VATS major lung resection in our center, and the prediction model of complications was established and verified. The model can provide basis for the prevention and intervention of postoperative complications in such patients, and accelerate the recovery of patients. METHODS: The clinical data of patients underwent VATS major lung resection in our center from January 2007 to December 2018 were collected retrospectively. Only patients with stage I-III lung cancer were included. The postoperative complications were registered strictly by TM&M classification system. The patients were divided into two groups according to the operation period: the early phase group (From 2007 to 2012) and the late phase group (From 2013 to 2018). The baseline data of the two groups were matched by propensity score matching. After matching, binary logistic regression analysis was used to establish the prediction model of complications, and bootstrap internal sampling was used for internal verification. RESULTS: A total of 2,881 patients with lung cancer were included in the study, with an average age of (61.0±10.1) years, including 180 major complications (6.2%). Binary Logistic regression analysis of 1,268 matched patients showed: age (OR=1.04, 95%CI: 1.02-1.06, P<0.001), other period (OR=0.62, 95%CI: 0.49-0.79, P<0.001), pathological type (OR=1.73, 95%CI: 1.24-2.41, P=0.001), blood loss (OR=1.001, 95%CI: 1.000-1.003, P=0.03), dissected lymph nodes (OR=1.022, 95%CI: 1.00-1.04, P=0.005) were independent risk factors for postoperative complications. The ROC curve indicates that the model has good discrimination (C-index=0.699), and the C-index is 0.680 verified by bootstrap internal sampling for 1,000 times. The calibration curve shows a good calibration of the prediction model. CONCLUSIONS TM&M system can comprehensively and accurately report the postoperative complications of thoracoscopic lung cancer surgery. Age, operative period, pathological type, intraoperative bleeding and dissected lymph nodes were independent risk factors for postoperative complications of VATS major lung resection for lung cancer. The established complication prediction model has good discrimination and calibration.

Objective: To investigate the effects of neonatal intensive care unit (NICU)-centered regional neonatal transport network (NTN) on the treatment of retinopathy of prematurity (ROP). Methods: A retrospective analysis was conducted to analyze the transfer, treatment and outcomes of 406 preterm infants with ROP who were transferred to the Bayi Children's Hospital Affiliated to the Seventh Medical Center of PLA General Hospital via the NTN from July 2008 to December 2014. Independent sample t-test, Chi-square test and Mann-Whitney nonparametric test were used for statistical analysis. Results: Among the 406 premature infants who were transferred to our hospital because of ROP, there were 257 males and 149 females with the gestational age of (29.5±1.9) weeks (24⁺⁵-36 weeks) and the birth weight of (1 234.8± 268.9) g (580-2 400 g). The age at transfer was (48.9±18.5) d (15-78 d) and the transport distance was (216.5±78.6) km (10-625 km). No death was reported during the transportation. Very preterm births and very low birth weight infants (VLBWI) accounted for 88.7% (360 cases) and 82.5% (335 cases), respectively. Lesions occurred in 1, 2 and 3 zones were detected in 98 (24.1%), 286 (70.4%) and 22 (5.4%) cases, respectively. Lesions of stage 1-5 were observed in 51 (12.6%), 156 (38.4%), 183 (45.1%), 12 (3.0%) and 4 (1.0%) cases. There were 186 cases (45.8%) with Plus lesions. A total of 252 cases (62.1%) underwent surgery which were achieving treatment standards, including 165 (65.5%) undergoing laser therapy, 93 (36.9%) receiving anti-vascular endothelial growth factor (VEGF) therapy, 16 (6.4%) having vitrectomy and two (0.8%) having scleral buckling. Eighteen infants were diagnosed with retinal structural abnormalities, among which 16 had retinal detachment before admission (12 in phase 4 and four in phase 5). Two without retinal detachment on admission developed to phase 4 after surgery. The incidence of retinal structural dysplasia was 0.9% (2/236) in infants receiving laser and/or anti-VEGF therapy in our hospital. Compared with the cured patients (n=234), those with retinal structural dysplasia (n=18) had a late transfer time [80 (38-270) vs 50 (19-150) d, Z=3.387, P<0.001]. Conclusions The NICU-centered and regional transfer-based ROP treatment network provides timely and effective treatment for infants with ROP.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.

Objective To identify the epidemiological changes in invasive fungal infection (IFI) in a neonatal intensive care unit (NICU) to provide information for prevention and treatment of IFI.Methods A total of 102 cases who were diagnosed with IFI among 42 187 neonates hospitalized in the NICU of Affiliated BaYi Children's Hospital,Chinese People's Liberation Army General Hospital from January 1,2009 to December 31,2014 were enrolled in this study.Since January 1,2012,the divisions of our NICU were more specific and intravenous fluconazole was administered as a routine preventive measure for high-risk infants.Clinical information of the IFI cases including general features,incidence,distribution of pathogens and drug (Amphotericin B,Fluconazole,Flucytosin,Itraconazole and Voriconazole) sensitivity were analyzed between former period (January 1,2009 to December 31,2011) and latter period (January 1,2012 to December 31,2014) by Chi-square test.Results The total incidence of IFI was 2.42‰ (102/42 187),and among the 102 IFI cases,73.5％ (75/102) were preterm infants and 75.5％ (77/102) were low birth weight infants.The incidence ofIFI in the latter period was lower than that in the former period [1.8‰ (48/26 046) vs 3.3‰ (54/16 141),x2=9.329,P＜0.01].The incidences of IFI in neonates with gestation age ＜28,≥ 28-＜32 and ≥ 32-＜37 weeks in latter period were decreased as compared with those in former period [10.6 ‰ (3/284) vs 76.9 ‰ (9/117),x2=12.569;6.1‰ (13/2 134) vs 21.9‰ (28/1 277),x2=16.868;1.4‰ (12/8 706) vs 1.9‰ (10/5 256),x2=7.165] (all P＜0.01).Altogether 103 pathogen strains were identified from 102 IFI cases as one Candida parapsilosis strain and one Laurent cryptococcus strain were both isolated from one patient.The most prevalent three pathogens were Candida albicans [51.5％ (53/103)],Candidaparapsilosis [24.3％ (25/103)] and Candida glabrata [8.7％ (9/103)].The isolated rates of Candida albicans and Candida glabrata strains in the latter period were higher than those in the former period [63.3％ (31/49) vs 40.7％ (22/54),x2=5.218;18.4％ (9/49) vs 0.0％ (0/54),x2=10.868],while the isolated rate of Candida parapsilosis strain was lower in the latter period than that in the former period [12.2％(6/49) vs 35.2％(19/54),x2=7.355] (all P＜0.05).All pathogen strains were sensitive strains except one Candida krusei strain which was isolated in the former period and was resistant to Fluconazole.Conclusions Premature infants born at lower gestational ages or with low birth weights are still at high-risk of IFI,but the incidence of IFI has declined in recent years.Routine administration of fluconazole in high-risk infants in NICU could prevente IFI without increasing drug resistance.Candida albicans is the predominant pathogen ofIFI.

Aim To investigate the effect of berberine on the expression of nephrin, podocin and intergrinα3β1 in diabetic nephropathy ( DN ) rat model, and further probe in to the renoprotective effects of berber-ine and its potential mechanisms. Methods The rat model of DN was induced by intraperitoneal injection of streptozotocin ( STZ ) after fed with high-sugar and high-fat diet for six weeks. The rats were assigned into 6 groups randomly: normal control group, DN model group, BBR (50,100 and 200 mg·kg-1 ) treatment group and enalaprilat positive control group ( 1 mg · kg-1 ) . The distribution and expression of kidney podocyte related proteins nephrin, podocin and interg-rinα3β1 were detected by immunohistochemical meth-od following electron microscopy observation ( × 1000 ) and high magnification observation( × 400) and West-ern blot. Results The podocyte related protein neph-rin, podocin and intergrin α3β1 were mainly distribu-ted in podocyte, but slightly different. Compared with normal control group, the expresion of podocyte related protein nephrin, podocin and intergrin α3β1 was de-creased obviously; compared with model group, BBR (100 and 200 mg·kg-1 ) treatment group could sig-nificantly suppress the abnormalities of pathological changes of the kidney and upregulate the expression levels of podocyte specific protein nephrin, podocin and intergrin α3β1 in the kidney of diabetic rats with nephropathy. Conclusions Berberine could alleviate the abnormalities of kidney pathological changes and proteinuria production in the DN model rats, which may be related to the upregulation of the expression of the podocyte proteins nephrin, podocin and intergrinα3β1.

Aim To investigate the renoprotective effect of berberine in diabetic nephropathy rat model. Methods The rat model of DN was induced by intra-peritoneal injection of streptozotocin ( STZ ) after fed with high sugar and high fat diet for six weeks. The rats were divided into 5 groups randomly, i. e. normal control group, model group, BBR ( 50 mg · kg-1 ) , BBR ( 100 mg · kg-1 ) and BBR ( 200 mg · kg-1 ) treatment group. The fasting blood glucose ( FBG) was evaluated at 2, 4, 6,8 week respectively. The patho-logical changes in the kidney were determined by PAS staining. The expression of vascular endothelial growth factor ( VEGF) was detected by immunohistochemistry and Western blot respectively. Results Compared with normal control group, the value of FBG, SCr, BUN and UTP of model group were sharply increased.
Compared with model group, the value of FBG in ber-berine different dosage treatment groups were signifi-cantly decreased to various degrees, and berberine dif-ferent dosage treatment could decrease the levels of SCr, BUN and UTP in different degree. Berberine could surpress the alterations of pathological changes in the kidneys and downregulate the expression levels of VEGF in the kidney of diabetic rats with nephropathy. Conclusion Berberine could significantly ameliorate the biochemical indicators and renal injury of the model rats through affecting the abnormal expression levels of VEGF in the kidney.
