The expression of Toll-like receptor 4 (TLR4) in neonatal cord blood mononuclear cells (MNCs) and serum TNF-α were investigated in order to explore the roles of TLR4 in the pathogenesis of preeclampsia. The study enrolled 27 patients suffering from preeclampsia (experimental group) and 21 normal pregnancy patients (control group). After MNCs were separated, the expression of TLR4 mRNA and protein was detected by using real-time quantitative PCR and Western blotting respectively, and the expression of TNF-α by using ELISA. The results showed the TLR4 mRNA level in cord blood MNCs (2(-ΔCT): 0.07±0.17), TLR4 protein expression level (absorbance ratio: 0.81%±0.15%) and TNF-α level (9.5±1.73 pg/mL) were all increased in experimental group as compared with control group with the differences being statistically significant (P<0.05). There was a positive correlation between the expression of TLR4 mRNA and TNF-± in both experimental group and control group (r=0.54 and 0.53, respectively, P<0.05). It was concluded that TLR4 expression in the experimental group of cord blood MNCs was increased and there was a positive correlation between the expression of TLR4 mRNA and TNF-α in both groups. TLR4-mediated release of inflammatory cytokines may be one of the important reasons leading to preeclampsia.

Objective To evaluate the effect of nitrous oxide-inhale combined with lidocaine-injection by Ciliao and Uterine points and single therapy in labor analgesia,and the impact on maternal and child.Methods 400 cases were randomly divided into four groups.Observation group:100 cases take the therapy of Nitrous oxide-inhale combined with lidocaine-injection in Ciliao and Uterine points in the time of active period.Control group 1:100 cases take the therapy of gas mixture-inhale( 50％ Nitrous oxide and 50％ Oxygen) in the time of active period.Control group 2:100 cases take the therapy of lidocaine-injection in Ciliao and Uterine points in the time of active period.Control group 3:100 cases do not take any analgesia.Analgesic effects,labor time,mode of delivery,neonatal conditions,the amount of bleeding in every group were observed.Results There was statistically significant differences between the observation group with the control group 1,2,3 on analgesic effects ( x2 =48.513,P ＜ 0.05 ) labor time( F =782.88,1120.81,1104.57,all P ＜ 0.05 ),mode of delivery ( x2 =85.715,P ＜ 0.05 ),neonatal conditions,the amount of bleeding( F =422.66,P ＜ 0.05 ).Conclusion Combination therapy was more effective than the single treatment.

Objective To analyze the changes in the disease spectrum of hospitalized patients with neurological diseases in a tertiary hospital in the past 5 years,in order to effectively develop targeted disease prevention and treatment strategies.Methods Collect case data of neurological diseases in a tertiary hospital from January 1,2018 to December 31,2022,and use ICD-10 coding for disease classification,and analyze the disease type,gender,age groups,and other factors.Results A total of 9060 patients with neurological diseases were admitted in the past five years.In 2020,the number of discharged patients affected by the COVID-19 was the smallest,accounting for 15.96% ,and in 2022,the number was the largest,accounting for 24.05% .The number of cases showed an increasing trend.There was no statistically significant difference in the composition of male and female patients;There is a statistically significant difference in the number of cases among patients of different age groups,and the incidence categories are different;The top 10 diseases in the ranking of neurological diseases are:transient ischemic attack,headache,spinal nerve disease,neurological disorders,epilepsy,Parkinson's disease,sleep disorders,paralysis,other brain diseases,hydrocephalus.The distribution of the top 10 diseases by gender has statistical significance.Conclusion The hospital can formulate the diagnosis and treatment technology for different age groups according to the distribution characteristics of disease spectrum,carry out comprehensive prevention and treatment measures for key groups,strengthen the construction of key special-ties and allocate health resources properly.
