In order to understand the status of neonatal transport research at home and abroad,we summarized and analyzed the research progress of neonatal transport through the literature search.Thus we evaluated the current application of a variety of transport critical rating system.Intrauterine transport is considered the safest mode of transport,and promote intrauterine transport of high-risk mothers.It is suggested that the parents participate in the transshipment process and return the stable children to the local hospital for further treatment and promote the family-centered treatment mode.In transit,mobile ECMO,hypothermia and other advanced equipment in foreign countries have been applied.It is recommended to use the respiratory function monitor to monitor the respiration during transit.It can provide the parameters of respiratory wave,identify air leak,accidental release,spontaneous breathing.

Objective To investigate of the MMI-166 on the expression of MMP-2,MMP-9 and the cell apoptosis of nude mouse xenografts of SW1990 human pancreatic cancer cells.Methods Establishment of control and experimental groups,randomly,the human pancreatic cancer xenograft model of SW1990 was constructed.The control group was treated with normal saline,and experimental group was treated with MML-166 (200 mg · kg-1 · d-1).The tumor volume and tumor inhibition rate was measured by vernier caliper through length and short diameter.The expression of MMP-2 and MMP-9 protein was observed using immunohistochemistry in the tumor tissues.Apoptosis index was detected by deoxynucleotidyl transferase-mediated nick end labeling (TUNEL method).Results The tumor volume of MMI-166 group (1252.30± 464.84) mm3 was less than the control group (2241.82±208.06) mm3,significantly.The inhibition rate was 34.47％ between the experimental groups (treat with MMI-166) (1.42±0.15) g and control group (2.17±0.20) g.The expression of MMP-2 (2.80 ± 1.10) ％ and MMP-9 (2.60 ± 1.52) ％ protein was significantly downregulated in MMI-166 group,compared with the control group.Apoptotic index in the experimental group (75.60±9.71) ％ was higher than the control group (17.40 ± 10.14) ％,significantly.Conclusion The mechanism of MMI-166 inhibiting pancreatic tumor growth and inducing apoptosis may be related to the suppression of MMP-2 and MMP-9 protein expression.

Objective To apply Six-minute Walk Test (6MWT) in acute stroke patients and analyze the results. Methods From Novem-ber, 2014 to January, 2015, 29 acute stroke patients with multiple or single infarction accepted 6MWT. The distance, distance per minute, blood pressure and heart rate before and after test, adverse events or discomforts during the test were recorded. Weak and fatigue scores were calculated. Results The mean of distance in acute stroke patients was (240.1±17.2) m, that was (46.8±3.3)%of the predicted values in the healthy. Male patients walked (255.4±21.40) m, not different from (214.9±28.4) m in female (t=-1.151, P=0.26). The distance liked to be negatively correlated with age (r=-0.356, P=0.058). The distance was similar in each minute. Weak score was (46.8±3.3)%, fatigue score was mostly between-20 and 20, and no correlation was found between them. Blood pressure and heart rate increased significantly at the end of the test (t>2.476, P<0.05). Few of patients complained mild discomforts. Conclusion 6MWT is safe and suitable for acute stroke patients for physical mobility judgement, but adverse events need to be cared.

Objective To evaluate the clinical efficacy of Radical TUR-BT combined with intra-arterial chemotherapy in the treatment of stage T2 N0 M0 localized muscle-invasive bladder cancer (MIRC).Methods The clinical data of 91 patients with T2 N0 M0 localized myometrial invasive bladder cancer admitted from January 2010 to December 2015 in the people's Hospital of Xinjiang Uyghur Autonomous Region were retrospectively analyzed,76 cases were males,15 cases were female,average age was 63.2 years old,age range 39-91 years old.Patients were divided into BPT group (n =34) and RC group (n =57) according to different surgical methods.Patients in the BPT group underwent Radical TUR-BT + intra-arterial chemotherapy,and patients in the RC group underwent radical cystectomy + urinary diversion.The median follow-up time,2-year progression-free survival,5-year disease-specific survival rate,overall survival and Karnofsky performance status (KPS) were compared between the two groups.Measurement data were expressed as mean ± standard deviation (Mean ± SD),t test was used for comparison between groups;and Chi-square test was used to compare the count date between groups.Using KaplanMeier method to depict disease-specific survival time in two groups.Quality of life evaluation using Karnofsky score,Evaluate the quality of life and health status of the two groups 3 months before and after treatment.Results The median follow-up time of BPT group and RC group were 35 months and 33 months.The 2-year progression-free rates in the BPT and RC groups were 73.5％ and 75.4％,respectively,and the difference was not statistically significant (P =0.758).The 5-year disease-specific survival rates of the two groups were 72.4％ and 74.8％,respectively,and the difference was not statistically significant (P =0.780).The overall survival rates of the two groups were 61.8％ and 63.2％,respectively,and the difference was not statistically significant (P =0.103).There was no significant difference in preoperative KPS score between the two groups (P =0.652).The KPS score of the BPT group was significantly higher than that of the RC group at 3 months after surgery.The difference was statistically significant(P =0.034).Conclusions For patients with localized MIBC with clinical stage of T2 N0M0.Radical TUR-BT combined with intra-arterial chemotherapy has similar effects to RC.This treatment can effectively improve the prognosis,preserve the bladder,and improve the quality of life for patients.

Objective To study the transport risk and factors that influence deaths of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.Method All infants transferred to our neonatal intensive care unit (NICU) by our hospital transport team or local hospital transport team from January 2014 to December 2015 were included in our study.Their clinical data were retrospectively studied.The risks of transport between hospitals were analyzed.The risk factors of deaths within and after 7 days of admission were further analyzed by multivariate Logistic regression analysis.The receiver operation characteristic (ROC) curve was used to assess the sensitivity and specificity of mortality index for neonatal transportation (MINT),transport related mortality score (TREMS),transport risk index of physiologic stability (TRIPS) for predicting mortality of preterm infants.Result (1) A total of 527 cases of ELBW/VLBW infants were included in our study.There were no deaths during transport.There were 10.2％ (54/527) died within and 8.9％ (42/473) died after 7 days of hospitalization.(2) Multivariate Logistic regression analysis showed that scleredema of newborn,secondary transport,gastrointestinal malformations,metabolic acidosis,high TREMS score,and high MINT score were risk factors of mortality within 7 days of admission for ELBW/VLBW infants;necrotizing enterocolitis,intraventricular hemorrhage ≥ three degree,high MINT score and low admission weight were risk factors of mortality after 7 days of admission.(3) The area under the ROC curve for MINT,TREMS,and TRIPS score were 0.672,0.655 and 0.665,respectively.The cut-off values for MINT score (cut-off 8,sensitivity 0.444,specificity 0.829),for TREMS score (cut-off 2,sensitivity 0.500,specificity 0.757,for TRIPS score (cut-off 20,sensitivity 0.444,specificity O.829) were selected to predict mortality within 7 days of admission.Conclusion (1) Secondary transport is the transport-related risk factor of mortality within 7 days of admission for ELBW/VLBW infants.(2) High MINT score is the risk factor of mortality within and after 7 days of admission.(3) If MINT ≥ 8,TREMS ≥2,or TRIPS ≥20,it might significantly increase the risk of mortality of ELBW/ VLBW infants within 7 days of admission after transport.

Diabetes secondary to pancreatic exocrine insufficiency is commonly referred to as pancreatogenic diabetes or type 3c diabetes.Among all diabetic patients in the western population,the prevalence of type 3c diabetes is about 5%-10%,but some patients with pancreatogenic diabetes are misdiagnosed as type 2 diabetes.So far,researches on pancreatogenic diabetes are being explored.The definition,diagnosis,prevalence,pathogenesis,clinical features and treatment status of pancreatogenic diabetes are described and analyzed in this paper.

Objective To assess the feasibility of sound touch elastography(STE)and sound touch quantify(STQ)in convex transducer and linear transducer for female levator ani muscles stiffness assessment.Methods A total of 69 healthy volunteers underwent STE and STQ examinations of the right levator ani muscles at three different locations(anterior,middle,and posterior)during rest,contraction,and stretch states.The study analyzed the success rate,variability,and measurements(Young's modulus)of the detection techniques,as well as assessed the inter-operator and intra-operator consistency.Results Both convex transducer STE and linear transducer STQ techniques exhibited higher overall success rates and lower variability in detecting the middle segment of the levator ani muscles compared to convex transducer STQ and linear transducer STE techniques,with statistically significant differences(all P<0.05).There was statistically significant difference in the measurements of levator ani muscles detected by convex transducer STQ technique and linear transducer STE technique(P<0.05).There was no statistically significant difference in the measurements of levator ani muscles detected by convex transducer STE technique and linear transducer STQ technique(P>0.05).The inter-operator and intra-operator consistency of convex transducer STE and linear transducer STQ technology were determined to be 0.869,0.919,0.772,0.850,respectively.Conclusion Both convex transducer STE and linear transducer STQ techniques demonstrate high success rates and low variability in assessing levator ani muscles stiffness,and there was no significant difference in the measurements of them,they were suitable for clinical promotion widely.

Objective:To compare and analyze the technical success rate and safety between computed tomography(CT)-percutaneous radiological gastrostomy (PRG) and percutaneous endoscopic gastrostomy (PEG).Methods:From January 2017 to January 2022, at the First Affiliated Hospital of Zhengzhou University, the data of 76 patients who underwent gastrostomy due to inability to eat orally were collected, including 38 patients in PEG group and 38 patients in CT-PRG group. Surgical outcomes and complications were compared between the PEG and CT-PRG groups. Surgical outcomes included technical success rate, operation time, postoperative body mass index and hospital stay; while complications included minor complications (such as perifistula infection, granulation tissue proliferation, leakage, pneumoperitoneum, fistula tube obstruction, fistula tube detachment and persistent pain) and serious complications (such as bleeding, peritonitis, colonic perforation and death within 30 d). Independent sample t test, chi-square test, and Fisher exact probability test were used for statistical analysis. Results:The technical success rate of CT-PRG group was higher than that of the PEG group (100.0%, 38/38 vs. 78.9%, 30/38), and the operation time was shorter than that of the PEG group ((17.16±8.52) min vs. (29.33±16.22) min), and the differences were statistically significant ( χ2=1.19, t=2.36; P=0.038 and 0.011). There were no significant differences in postoperative body mass index ((16.29±3.56) kg/m 2 vs. (16.12±3.17) kg/m 2) and hospital stay ((4.13±1.26) d vs. (3.52±1.13) d) between PEG group and CT-PRG group (both P>0.05). The incidence of minor complications in the PEG group was 42.1% (16/38), including 6 cases of perifistulal infection, 1 case of leakage, 5 cases of fistula tube obstruction, 1 case of fistula tube detachment, and 3 cases of persistent pain. The incidence of serious complications was 5.3% (2/38), including 1 case of bleeding and 1 case of colonic perforation. The incidence of minor complications in the CT-PRG group was 39.5% (15/38), including 5 cases of perifistula infection, 1 case of granulation tissue proliferation, 3 cases of pneumoperitoneum, 3 cases of fistula tube obstruction, 2 cases of fistula tube detachment, and 1 case of persistent pain. The incidence of serious complications was 0. There was no significant difference in the incidence of minor complications between the PEG group and the CT-PRG group ( P>0.05), while the incidence of serious complications in the CT-PRG group was lower than that of the PEG group, and the difference was statistically significant (Fisher exact probability test, P=0.043). Conclusion:PEG is a safe and effective method of gastrostomy, but for patients with esophageal obstruction, CT-PRG can be an effective supplement to PEG.

Objective:To study the clinical features and treatment strategy of neonatal ureaplasma meningitis.Methods:During 2021, the clinical data of 2 neonates with ureaplasma meningitis treated in Children's Hospital of Hunan Province were retrospectively analyzed. Literature on this subject were searched in the following databases: CNKI, Wanfang Database, Chinese Medical Journal Full-Text Database, CQVIP database, SinoMed, PubMed, Embase and Web of Science (up to March 2022). The key words included “infant”, “neonate”, “newborn”, “ureaplasma”, “mycoplasma urealytium”, “meningitis”, “central nervous system infection”, “brain”. The clinical data, treatment and prognosis of patients from the literature were summarized.Results:Case 1, female, gestational age(GA) 33 +3 weeks, intracranial hemorrhage (ICH) and ventricular dilatation were found on 2 d after birth. The cerebrospinal fluid (CSF) routine and biochemistry tests indicated meningitis, but the CSF culture was negative. No improvement after antibiotic treatment. CSF metagenomic next-generation sequencing (mNGS) and 23S rRNA showed Ureaplasma urealyticum on 30 d after birth. The patient was treated with doxycycline (DOX) for 21 d until mNGS turned negative and DOX was discontinued. However, the disease recurred 23 d later and erythromycin was added with DOX as combined therapy. The patient was followed up until 6 months without neurodevelopmental disabilities. Case 2, male, GA 26 weeks, ICH and ventricular dilatation were found on 10 d after birth. The CSF routine and biochemistry tests indicated meningitis, but the CSF culture was negative. No improvement after antibiotic treatment. CSF mNGS and 23S rRNA showed Ureaplasma parvum. The patient received erythromycin therapy for 32 d and had normal neurodevelopment at 5 months. According to the literature, 43 cases were reported including the 2 cases descirbed above, 17 cases were full-term infants and 26 cases were preterm infants. The median CSF leukocytes, glucose and proteins were 566 cells/mm 3, 0.2 mmol/L and 2.2 g/L. 27 cases were diagnosed based on CSF culture, 6 cases using mNGS, 4 cases with both CSF culture and PCR method and 6 cases with other methods. Macrolides alone were used in 14 cases, macrolides combined with another antibiotic were used in 8 cases, non-macrolide antibiotics were used in 9 cases and 12 cases didn't receive any anti-ureaplasma therapy. All 17 term infants survived, however, 8 cases with hydrocephalus. Among the 26 preterm infants, 8 patients died, 18 patients had periventricular-intraventricular hemorrhage and 15 patients had hydrocephalus. Conclusions:Neonatal ureaplasma meningitis has significantly lower CSF glucose level with hydrocephalus as the common complication. For intracranial infections of unknown etiology and no response to treatment, mNGS is helpful in determining the pathogen.Neonatal ureaplasma meningitis should be treated with macrolides alone or as add-on therapy.

Objective To investigate the similarities and differences in the pathophysiological responses caused by different infection sites in sepsis patients and to evaluate the clinical significance of the source of infection on the prognosis of patients.Methods A total of 159 patients with a clear source of infection in Foshan Hospital of Traditional Chinese Medicine from January 1,2021 to January 1,2023 were selected and divided into survival group(n=98)and death group(n=61)based on their survival status within 28 days.The independent risk factors affecting the prognosis of sepsis patients were determined by multivariate Logistic regression analysis.The 28-day mortality rates of different infection source groups were compared,and the distribution differences of serum biomarkers in different infection source groups were explored by analysis of variance.Results Among the 159 patients,the frequency of infection source distribution was as follows in descending order:Respiratory tract(62.89％),urinary tract(13.84％),abdomen(13.21％),skin and soft tissue(10.06％).Multivariate Logistic regression analysis showed that age,procalcitonin,sepsis-related organ failure assessment score,and respiratory tract infection source were significant risk factors affecting the 28-day mortality of sepsis patients(P＜0.05).Different infection source groups showed different degrees of differences in inflammation,coagulation,and organ dysfunction,with heterogeneity.Conclusion The differences in the source of infection lead to significant differences in the pathophysiological features(inflammatory response,coagulation activation,and organ dysfunction)and short-term prognosis(28-day mortality)of sepsis.
