Objective:To study the effects of TCM ointment rubbing technique on pain, swelling, and knee joint function in patients with knee osteoarthritis (KOA) after total knee arthroplasty (TKA).Methods:A randomized controlled trial was conducted. In this study, 80 patients with KOA who underwent TKA treatment in the Department of Sports Medicine I, Wangjing Hospital, China Academy of Traditional Chinese Medicine from October 2022 to March 2024 were taken as the study subjects. They were divided into two groups with random number table method, with 40 cases in each group. Both groups were treated with conventional Western medicine + rehabilitation training after surgery, and the observation group was combined with TCM paste mo technique on this basis. VAS score was used to assess the degree of pain at different time points, and skin fold was used to measure the circumference of the upper knee circumference and the circumference of the lower knee circumference, and knee Injury and osteoarthritis outcome score (KOOS) was used to assess the degree of knee joint function recovery.Results:After treatment, the observation group after surgerythe at 7 d (2.57 ± 0.84 vs. 4.00 ± 0.85, t=7.54) and 14 d (0.80 ± 0.93 vs. 2.70 ± 1.04, t=8.56) VAS scores were lower than those in the control group ( P<0.001). After treatment, the observation group after surgerythe at 7 d the superior circumference [(48.32 ± 4.57) cm vs. (50.53 ± 3.97) cm, t=2.32], and inferior circumference [(36.71 ± 2.95) cm vs. (39.21 ± 6.86) cm, t=2.12], at 14 d the superior circumference [(45.68 ± 4.69) cm vs. (47.96 ± 3.89) cm, t=2.37], and inferior circumference [(34.96 ± 2.96) cm vs. (36.70 ± 4.35) cm, t=2.10] were lower than those in the control group ( P<0.05). The observation group after surgerythe at 14 d the the knee joint mobility [(115.32 ± 2.12) ° vs. (113.34 ± 2.16) °, t=4.14] and KOOS scores (85.52 ± 0.82 vs. 80.32 ± 1.13, t=23.56) were higher than those in the control group ( P<0.01). Conclusion:TCM ointment rubbing technique has significant advantages in improving pain, swelling and knee joint mobility after artificial knee arthroplasty, which can effectively restore knee joint function.

Objective To observe the values of changes of right heart modified myocardial performance index(Mod-MPI)and ductus venosus(DV)spectrum parameters in pre-eclampsia fetuses for predicting adverse pregnancy outcomes.Methods Eighty-one pregnant women diagnosed as pre-eclampsia were prospectively enrolled and divided into severe pre-eclampsia(SPE)group(n=39)and mild pre-eclampsia(MPE)group(n=42),while 85 healthy pregnant women were taken as controls(control group).Fetal right heart function parameters,including right ventricular isovolumetric relaxation time(IRT),isovolumetric contraction time(ICT),ejection time(ET),total spent time(TST),Mod-MPI,tricuspid valve peak flow velocity ratio in early and late diastole(TV-E/A),as well as blood flow velocities in each waveform of DV spectrum(S,V,D,and A wave)were obtained,and the pulsatility index(PI)and the ratio of blood flow velocities in each waveform of the DV(S/V,S/D,S/A,V/D,V/A,D/A)were calculated.Intrauterine fetal distress,preterm delivery,neonatal asphyxia and newborn with low weight were considered as adverse pregnancy outcomes.The correlations of right heart Mod-MPI and TV-E/A with DV parameters in pre-eclampsia fetuses were assessed,and their predictive efficacies for adverse pregnancy outcomes were evaluated for right heart Mod-MPI and DV using the receiver operating characteristics(ROC)and the area under the curves(AUC).Results Compared with control group and MPE group,fetal right heart IRT,ICT and Mod-MPI increased and ET decreased in SPE group(all P＜0.05).No significant differences of right heart TST and TV-E/A among 3 groups(both P＞0.05).Fetal DV A-wave velocity and V/D values progressively decreased but PI progressively increased in control,MPE and SPE groups(all P＜0.05).Fetal right heart Mod-MPI in pre-eclampsia was moderately positively correlated with DV PI(r=0.637,P=0.016),while TV-E/A was weakly negatively correlated with DV V/D(r=-0.355,P=0.043).Adverse pregnancy outcomes were noticed in 59 pre-eclampsia cases.The AUC of fetal right heart Mod-MPI and DV PI for predicting adverse pregnancy outcomes in pre-eclampsia cases was 0.897 and 0.848,respectively,without significant difference(Z=0.460,P=0.400).Conclusion Changes of right heart Mod-MPI and DV spectrum parameters in pre-eclampsia fetuses had high value for predicting adverse pregnancy outcomes.

Objective:To investigate the value of fetal heart quantification (fetal HQ) in assessing ventricular function of fetuses with small-for-gestational-age (SGA) and fetal growth restriction (FGR).Methods:A total of 152 singleton pregnancies with estimated fetal weight (EFW) or abdominal circumference less than the 10th percentile in the Third Affiliated Hospital of Zhengzhou University were prospectively selected from August 2022 to September 2023, where fetal EFW or abdominal circumference were in the 3rd to 9th percentile with normal Doppler findings were classified as the SGA group ( n=79), and the rest as the FGR group ( n=73). In the same period, 161 cases of normal single fetuses were matched as the control group.Based on the gestational week in which FGR occurred, the FGR group were categorized into the early-onset group (<32 weeks, n=46) and the late-onset group (≥32 weeks, n=27), and fetuses in the FGR group with absent end-diastolic velocity of the umbilical artery were defined as severe FGR ( n=11), and the rest as mild FGR ( n=62). Fetal ventricular fractional area change (FAC), global longitudinal strain (GLS), longitudinal fractional shortening (LFS) and 24-segment fractional shortening (FS) were obtained by fetal HQ. The cardiac systolic function between groups were compared, the correlations between each parameter and gestational week were analyzed, the inter-observer and intra-observer repeatability tests were performed. Results:Compared with the control group, ventricular FAC, LFS, and GLS were lower in the SGA and the FGR group, right ventricular FS of segments 9-24 were reduced in the SGA group, and left ventricular FS of segments 10-19, 21-24 and right ventricular FS of segments 18-24 were reduced in the FGR group, the differences were statistically significant (all P<0.05). Left ventricular GLS, LFS and right ventricular FAC, GLS, LFS, FS of segments 1-14 were lower in the severe FGR group than in the mild FGR group, the differences were statistically significant (all P<0.05). The values of left ventricular GLS and LFS were higher in the early-onset FGR group than in the late-onset FGR group, the differences were statistically significant (all P<0.05). The ROC showed that the ventricular systolic function parameters predicted adverse perinatal outcomes with an AUC>0.6 (all P<0.05). Left ventricular GLS and right ventricular partial-segments FS were no correlations with gestational week in the FGR group (-0.3< rs<0.3, all P<0.05). There was no correlation between the parameters and gestational week in the SGA group (all P>0.05). The inter-observer and intra-observer intraclass correlation coefficients (ICC) were >0.75, with good reproducibility. Conclusions:Fetal HQ can quantitatively assess the changes of ventricular function in SGA and FGR fetuses, and the ventricular overall, longitudinal and localized contractile function in SGA and FGR fetuses are reduced, and abnormal ventricular systolic function is associated with adverse perinatal outcomes.

Deep brain stimulation(DBS),including optical stimulation and electrical stimulation,has been demonstrated considerable value in exploring pathological brain activity and developing treatments for neural disorders.Advances in DBS microsystems based on implantable microelectrode array(MEA)probes have opened up new opportunities for closed-loop DBS(CL-DBS)in situ.This technology can be used to detect damaged brain circuits and test the therapeutic potential for modulating the output of these circuits in a variety of diseases simultaneously.Despite the success and rapid utilization of MEA probe-based CL-DBS microsystems,key challenges,including excessive wired communication,need to be urgently resolved.In this review,we considered recent advances in MEA probe-based wireless CL-DBS microsystems and outlined the major issues and promising prospects in this field.This technology has the potential to offer novel therapeutic options for psychiatric disorders in the future.

Objective:To evaluate the systolic function of 24 segments in dichorionic diamniotic (DCDA) twin pregnancy by fetal heart qualification (fetal HQ) analysis, and to compare the difference with singleton pregnancies.Methods:Thirty-one cases of DCDA twin pregnancy (observation group) and 100 cases of singleton pregnancy (control group) matched in gestational age were enrolled. They underwent perinatal health care in the Third Affiliated Hospital of Zhengzhou University from February 2022 to February 2023.Fetal HQ was applied to track endocardial motion trajectories and automatically calculate the global strain (GS), fractional area change (FAC) and fractional shortening (FS) of 24 segments of left and right ventricles in order to compare the difference between DCDA fetuses and singleton fetuses. One case of twins with growth discordance were selected to demonstrate the utility of this technique.Results:①There were no statistically significant differences in GS, FAC and 24-segments FS of left and right ventricles between the two fetuses in the observation group (all P>0.05). ②The LV-FS of segments 1-10 were higher in the observation group than the control group, and the differences were statistically significant (all P<0.05). However, there were no statistically significant differences in GS and FAC of left and right ventricles, LV-FS of segments 11-24 and RV-FS of segments 1-24 between the observation group and the control group (all P>0.05). The intraclass correlation coefficient(ICC) was greater than 0.75, indicating good repeatability. ③Two fetuses with discordant growth in dichorionic diamniotic twins had abnormal FS in some segments of the left and right ventricles. Conclusions:Fetal HQ technology could easily and reliably evaluate fetal heart function in DCDA pregnancy with good repeatability. The changes of fetal cardiac function in twin pregnancy did not always follow the same pattern as in singleton pregnancy. The related data of singleton pregnancy should not be blindly used in the clinical management and scientific research of twin pregnancy.

Objective: To explore the effect of improving these traits through art therapy group meetings as a form of psychological counseling, so as to promote mental wellness among this population. Methods: A total of 74 hearing impaired students from grades 3 to 9 were surveyed with the Children s Self concept Scale (PHCSS) and Social Adaptability Scale. Eight art therapy group meetings, as a form of psychological counseling, were then held. Results: Self consciousness among hearing impaired students aged 10-12 and 13-16 years old was significantly lower than the national norm ( t =-6.51, -8.50, P <0.01). The social adaptability level of this group was very poor(2.89±8.26), and a significant positive correlation was found between self awareness and social adaptability among hearing impaired students. Further, self awareness could predict the social adaptability of these students ( F = 9.04 , P <0.05). After group psychological counseling intervention, there was significant increases in self consciousness among students from grades 3 to 9, and significant increases were also found in the social adaptability of students in grades 3, 4, 5, 6 and 8 ( P <0.05). Conclusion Self awareness shows certain influence on the social adaptability level of hearing impaired students, and group psychological counseling can promote social adaptability by improving self awareness among this population.
