Establishing a full-cycle contract management model for comprehensive public hospitals has practical signifi-cance for the development of smart hospitals.The aim is to create a hierarchical and classified contract management system fo-cused on information sharing.The method involves outlining the systematic processes of contract management within the hospital,analyzing common issues from multiple dimensions-such as management processes,level of information technology,and process supervision-and proposing solutions to meet the requirements of modern public smart hospital contract management.Based on in-formation sharing and hierarchical management,this approach offers ideas for refined management in hospitals and promotes the high-quality development of comprehensive medical services in smart hospitals..

Objective:To explore the effects of status epilepticus(SE)on neuronal processes and synapses in the cerebral cortex and hippocampus of young mice.Methods:The young mice of SE model was established by intraperito-neal injection of lithium chloride and pilocarpine.Morris water maze test was used to detect the behavioral changes in the mice.Immunofluorescence staining was used to observe the morphological changes of axons,dendrites and synaptic connections of neurons in the cerebral cortex and hippocampus of mice,and the ultrastructural changes of synapses of pyramidal neurons in the mouse hippocampus were observed with transmission electron microscopy.Results:The sei-zure rate of grade IV and above in mice was 80％,and the mortality rate was 25％.The escape latency of SE mice was prolonged(P＜0.05),the trajectory of exploring the platform was significantly longer and more complicated,and the time spent in the target quadrant and the number of crossing the platform were significantly reduced(P＜0.05).Posi-tive expression of axonal neurofilament marker protein SMI312 and microtubule-associated protein 2(MAP2)were found in the cerebral cortex and hippocampus of both groups,and the axonal neurofilaments and neuronal dendrites in the SE group were of different lengths and arranged densely and scatteredly.The positive expression of synaptophysin(SYP)and the number of positive spots increased significantly in in the hippocampus of SE group(P＜0.01).The number of synaptic vesicles in the SE group increased significantly,and the postsynaptic density(PSD)thickness decreased significantly(P＜0.01).Conclusion:SE might lead to acute injury of synapses in the cerebral cortex and hippocampal area of young mice,induce synaptic vesicle circulation disorders,and then cause widespread destruction and disorder of the axon and dendrite networks,the reactive or compensatory reconstruction of synaptic.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Objective:To study the clinical and genetic characteristics of familial paroxysmal exercise-induced dyskinesia with Parkinson-like manifestations in the elderly.Methods:Clinical data of 9 family members were analyzed, including 2 patients(both received treatment)consenting to appropriate therapy and prediction protocols.DNA was extracted from peripheral blood samples, and then second-generation sequencing mutation screening.Results:The tremor of two probands in the family was completely brought under control by oxcarbazepine treatment.In 5 family members, a heterozygous mutation of base G>C in exon 2 c. G366C: P.QCon122H at position 29824741 of the PRRT2 gene was found, resulting in the mutation of the amino acid at 122 from glutamine to histidine, which was predicted by SIFT and M-CAP to be harmful.Sanger sequencing of pedigree samples showed that the sisters, brothers and nephews of the proband were heterozygous and their nieces were of the wild type.Conclusions:Q122 of PRRT2 protein can cause the Parkinson-like limb tremor phenotype, and antiepileptic drugs are also effective for paroxysmal exercise-induced dyskinesia in the elderly.

Background Essential and non-essential elements have an important impact on the development of the central nervous system during fetal development. Due to their less developed brain, preterm infants are more sensitive to element exposure, and are high-risk groups of neurodevelopmental abnormalities. However, it is not clear whether the effects of element exposure in utero on postpartum neurodevelopment are different between full-term infants and preterm infants. Objective To evaluate the effects of element exposure levels during pregnancy on neurodevelopment of children aged 6-24 months (of corrected age), and compare the effects between preterm and full-term children. Methods A prospective study design was adopted and this study was conducted based on the Maoming Birth Cohort Study (MBCS) in Maoming City, Guangdong Province. Twenty elements in cord blood of 197 preterm infants and 297 full-term infants were measured, including 11 essential trace elements [vanadium (V), chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), selenium (Se), strontium (Sr), tin (Sn), and iron (Fe)], and 9 non-essential trace elements [aluminum (Al), arsenic (As), thallium (Tl), lead (Pb), uranium (U), cerium (Ce), antimony (Sb), cadmium (Cd), and yttrium (Y)]. The neurodevelopment of the children at 6, 12, and 24 months were evaluated by the Ages and Stages Questionnaires-the Third Edition (ASQ-3). A generalized estimating equation (GEE) model was adopted to evaluate the associations between elements and neurodevelopment in full-term and preterm children separately. Results The positive rates of 10 elements (Mn, Cu, Zn, Se, Sr, Fe, Sb, Tl, Pb, and As) in cord blood were greater than 80%. Among the preterm birth children, the results of GEE analysis showed that after adjusting for the covariates, for each increase of interquartile range (IQR) in ln-transformed concentration, As was associated with problems/delay in the communication and problem-solving sub-scales, with the adjusted odds ratios (OR) and 95% confidence intervals (CI) of 1.36 (1.03-1.80) and 1.55 (1.10-2.20), respectively; the adjusted OR (95%CI) of problems/delay in the fine motor and problem-solving sub-scales were 1.44 (1.00-2.07) and 1.76 (1.09-2.84) for Sb, respectively; the adjusted OR (95%CI) of problems/delay in the communication sub-scale was 1.37 (1.09-1.74) for Se. No statistically significant associations between umbilical cord blood element concentrations and neurodevelopment indicators were observed among full-term children. The results of stratified analysis by sex showed that the associations between umbilical cord blood element concentrations and neurodevelopment problems/delay were only significant among female preterm children. Conclusion Exposures to As, Se, and Sb during pregnancy may increase the risk of neurodevelopment problems/delay in preterm children aged 6-24 months, and female seem to be more vulnerable.

Objective:To study the clinical characteristics of purulent meningitis complicated with hydrocephalus in neonates, and to analyze the risk factors of the disease.Methods:Neonates diagnosed with purulent meningitis complicated with hydrocephalus who hospitalized in the department of neonatology of the Second Affiliated Hospital of Wenzhou Medical University from January 2002 to August 2021 were selected as the case group. Neonates with positive pathogen cultures but no hydrocephalus during the same period were assigned by random number table method as the control group. The ratio of the control group and the case group was 2 ∶1. The clinical data such as bacteria distribution, cranial imaging, therapy and prognosis were compared between the two groups. The risk factors for hydrocephalus were predicted. Statistical analysis was conducted using chi-square test and multiple logistic regression analysis.Results:There were 33 cases in the case group and 66 cases in the control group. A total of 27 cases had confirmed pathogen results, of which 20 cases (74.1%) were Gram-negative bacteria and seven cases (25.9%) were Gram-positive bacteria. The time of diagnosis for hydrocephalus were 13.0(5.5, 28.5) days after the onset. Twenty-six cases received non-surgical treatment, while seven cases received surgery. The cure rate of case group was 42.4%(14/33), which was lower than that of control group (72.7%, 48/66), and the difference was statistically significant ( χ2=8.63, P=0.003). Univariate analysis showed that the incidences of protein>3 g/L in cerebrospinal fluid, glucose<2 mmol/L in cerebrospinal fluid, convulsions, central respiratory failure, intracranial hemorrhage and encephalomalacia in the case group were all higher than those in the control group, with statistical significance ( χ2=19.72, 12.04, 19.04, 5.73, 11.85 and 17.48, respectively, all P<0.050). Multivariate logistic regression analysis showed that convulsions (odds ratio ( OR)=4.476, 95% confidence interval ( CI) 1.091 to 18.363, P=0.037), intracranial hemorrhage ( OR=8.031, 95% CI 1.894 to 34.059, P=0.005) and encephalomalacia ( OR=35.189, 95% CI 2.954 to 419.150, P=0.005) were risk factors for neonatal purulent meningitis complicated with hydrocephalus. Conclusions:Gram-negative bacteria are common pathogen of neonatal purulent meningitis complicated with hydrocephalus. Convulsions, intracranial hemorrhage and encephalomalacia are important predictors for neonatal purulent meningitis complicated with hydrocephalus.

Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

Objective:To investigate the value of 3D printing combined with intraoperative electrophysiological monitoring in excision of cerebellopontine angle (CPA) tumor.Methods:The clinical data of 43 patients with CPA tumor, admitted to our hospital from October 2016 to October 2019, were collected and analyzed. These patients were voluntarily divided into ordinary group ( n=27) and optimized group ( n=16). Patients in the ordinary group were operated microscopically, and those in the optimized group were operated microscopically with 3D printing combined with intraoperative electrophysiological monitoring. The degrees of tumor resection and neurological functions (facial and auditory nerve function, swallowing function, limb activity) improvements were compared between the two groups. Results:The degrees of tumor resection of the optimized group were significantly higher than those of the ordinary group ( P<0.05), and the improvement of facial and auditory nerve function in the optimized group was significantly better than that in the ordinary group ( P<0.05). There was no significant difference in improvements of swallowing function and limb activity between the two groups ( P>0.05). Conclusion:The 3D printing combined with intraoperative electrophysiological monitoring can improve the resection rate of CPA tumor, protect the facial auditory nerve, and improve the quality of life of patients after surgery.

In recent years, osteoporosis (OP) has become one of the main diseases affecting the health of middle-aged and elderly people in China, and the prevalence of OP has increased significantly. The clinical diagnosis and treatment guidelines for this disease are also constantly updated. The overall principles speciallyemphasise that doctors and patients need to work together to negotiate the details of the diagnosis and treatment guidelines, in order to improve the OP clinical diagnosis and treatment rate. Therefore, patients′ knowledge of the disease, understanding of clinical guidelines, and cooperation with doctors to implement diagnosis and treatment plans are very important. In this study, from the most concerned issues of the patients, we established the OP patient practice guideline working group. 14 recommendations, as the OP patient practice guidelines, are proposed in accordance with the relevant principles of the "World Health Organization guidelines development manual" and the international normative process.

Objective To detect the expression and clinic significance of long non-coding RNA ZEB1-AS1 in breast cancer. Methods A total of 130 patients with breast cancer in Baoji Central Hospital of Shaanxi Province from June 2007 to April 2015 were selected. Quantitative real-time PCR(qRT-PCR)was used to detect the expression level of ZEB1-AS1 in breast cancer tissues and corresponding normal tissues,and the rela-tionships between the expression level of ZEB1-AS1 and the clinic characteristics of the patients and their overall survival time were analyzed. siRNA was used to disturb the expression of ZEB1-AS1. CCK-8 assay, clone formation assay and Transwell assay were used to detect the proliferation,cloning ability and migration of breast cancer MCF-7 cells in control group,siRNA-1 group and siRNA-2 group. Results The expression level of ZEB1-AS1 in breast cancer tissues was higher than that in corresponding normal tissues[M(QR ):0. 0016 (0. 0051)vs. 0. 0009(0. 0015);Z = - 4. 426,P < 0. 001]. The higher expression of ZEB1-AS1 was correlated with lymphatic metastasis(χ2 = 9. 148,P = 0. 027),negative human epidermal growth factor recep-tor 2(χ2 = 5. 039,P = 0. 025),triple negative breast cancer(χ2 = 4. 597,P = 0. 032). The patients with the higher expression of ZEB1-AS1 had a shorter overall survival time compared with the patients with the lower expression of ZEB1-AS1(χ2 = 14. 340,P < 0. 001). CCK-8 assay showed that knock down of ZEB1-AS1 after 72 h,the absorbance values of the control group,siRNA-1 group and siRNA-2 group were 0. 605 ± 0. 049, 0. 488 ± 0. 054,0. 417 ± 0. 038 respectively,with a statistically significant different( F = 15. 936,P <0. 001),and the two siRNA groups were significantly inhibited in cell proliferation compared with the control group(both P < 0. 05). The colonies of the control group,siRNA-1 group and siRNA-2 group were 297. 5 ± 11. 4,192. 0 ± 12. 1,204. 8 ± 12. 8 respectively,with a statistically significant different(F = 112. 526,P <0. 001),and the two siRNA groups were significantly inhibited in the cell clone compared with the control group(both P < 0. 001). The migratory cells numbers of the control group,siRNA-1 group and siRNA-2 group were 184. 5 ± 8. 6,147. 5 ± 18. 6,57. 6 ± 7. 3 respectively,with a statistically significant different( F =12. 409,P = 0. 001),and the two siRNA groups were significantly inhibited in the cell migration(both P <0. 001). Conclusion ZEB1-AS1 is overexpressed in breast cancer,overexpression of ZEB1-AS1 induces a shorter overall survival in breast cancer patients,and knock down of ZEB1-AS1 can inhibit the proliferation, migration and colony formation ability of the breast cancer cell line.
