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 analyze the bone mineral density and serum osteocalcin levels in postmenopausal women with idiopathic benign paroxysmal positional vertigo. Methods: A total of 64 postmenopausal women with idiopathic BPPV were selected as the study group, and 98 postmenopausal healthy women were selected as the control group. Bone mineral density and serum osteocalcin levels were analyzed and compared between the groups.χ² test was used for numeration data and t test was used for measurement data. Results: The prevalence of osteoporosis or osteopenia in BPPV group 67.2% (43/64) was significantly higher than that in the control group 51.0% (50/98) (χ²=4.139, P=0.042). Among BPPV subjects, there was a negative correlation between osteocalcin and bone density T (r=-0.469, P<0.001). Osteocalcin was found in normal bone mass subgroup (13.61±4.32)μg/L, decreased bone mass subgroup (17.49±7.61)μg/L, and osteoporosis subgroup (20.83±6.72)μg/L, respectively, and the difference was statistically significant (F=5.39, P=0.007). Conclusions Bone mineral density in BPPV group is lower than that in control group. The lower the bone mineral density of the patients, the higher the osteocalcin in BPPV group.

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.

Conclusions rBCG had inhibition to EB virus positive tumors in mice.

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 explore the effects of diversified continuing nursing on recovery of patients with breast cancer after modified radical mastectomy. Methods A total of 90 patients with breast cancer after modified radical mastectomy were divided into observation group ( 45 cases ) and control group ( 45 cases ) according to random number table method. Patients in two groups received health guidance before leaving hospital, while those in observation group also received continuing nursing after leaving hospital. One month after leaving hospital, recovery of flaps and function of affected upper limb were evaluated. Results The flaps recovery of patients in observation group were better than those in control group with a significant difference ( P<0. 05). There were statistically significant differences in horizontal abduction of shoulder joint, upward abduction of shoulder joint, dorsiflexion of middle finger, distance of seventh cervical vertebra between two groups ( P<0. 05). Conclusions Diversified continuing nursing can effectively reduce complications of breast cancer after modified radical mastectomy and promote function recovery of the upper limb of patients.

[ ABSTRACT ] AIM: To observe the effect of rapamycin on the apoptosis of mouse astrocytes in vitro.ME-THODS:The astrocytes from C57BL/6J newborn mouse pups were isolated and primarily cultured.The effect of rapamycin on the viability of astrocytes was assessed by MTT assay.The mean fluorescence intensity of SYTOX?Green stain in the astrocytes was detected by fluorescence microplate reader in order to analyze the effects of rapamycin on the cell death in-duced by H2 O2 , ionomycin and/or deferorxamin.DiOC6 (3) staining was used to analyze the mitochondrial membrane po-tential of the astrocytes induced by H2 O2 .Flow cytometry analysis was used to determine the production of ROS in the as-trocytes and mitochondria by staining with H2 DCFDA and MitoSOXTM Red reagent, respectively.RESULTS: Rapamycin at concentration of 0.5 μmol/L protected the astrocytes against cell death induced by H2 O2 or deferoxamine plus ionomy-cin.Rapamycin protected the mitochondrial membrane potential of astrocytes from the injury of H2 O2 .It also reduced the production of ROS in the astrocytes and decreased the level of ROS in the mitochondria.CONCLUSION:Rapamycin re-duces the ROS overload in the mitochondria, keeps mitochondrial membrane potential safety and protects the astrocytes a-gainst apoptosis in vitro.

Objective:To explore the effects of medical support program on local diagnosis,treatment and prognosis of acute myocardial infarction(AMI).Methods:Department of Cardiology,Zhongshan Hospital,Fudan University launched medical support program for Fuyuan People′s Hospital in Mar 2010.A total of 103 AMI patients admitted to Fuyuan People′s Hospital during Mar 2010 and Apr 2014 were enrolled.And 5 1 patients admitted during Mar 2010 and Nov 2012 were allocated to group A,while 52 patients admitted during Dec 2012 and Apr 2014 were allocated to group B.The treatment strategy,hospital stay, medication and prognosis were compared between the two groups.Results:Among the 103 AMI patients,male smoking pro-portion was significantly higher than female one(P <0.05).Only 21 patients with ST segment elevation myocardial infarction (STEMI)arrived hospital within 12 h.The thrombolytic therapy rate of patients with STEMI in group B was higher than that in group A(P <0.05).The usage rate of adenosine diphosphate(ADP)receptor antagonist(clopidegrel)during hospitalization in group B was higher than that in group A (P <0.05 ).Only 57 patients were followed up.And only 1/3 of these patients re-ceived consecutive coronary angiography and percutaneous coronary intervention(PCI).After discharge from hospital,the pre-scription rates of ADP receptor antagonist,β-receptor blockers and angiotension converting enzyme inhibitor (ACEI)all de-creased obviously and there was no significant difference between the two groups(P >0.05).There was no significant difference regarding the incidence rates of endpoint events between the two groups(P >0.05).Conclusions:Medical support program im-proves the rates of diagnosis and standardized treatment of AMI during hospitalization.However,the delay before admission has not been shortened yet.Furthermore,there was no standardized secondary prevention and treatment after discharge.Thus,apart from improving the ability of diagnosis and treatment during hospitalization,more attention should be paid to the health education for patients and the training for primary medical staff,and enhance the regional cooperation.
