Objective To analysis the clinical pathway management efficiency under different DRG groups, for a basis for further optimizing clinical pathway management. Methods The retrospective analysis method was used to compare the average length of stay, sub-average costs, and drug proportions of patients with different DRGs in the same clinical pathway. Shapiro-Wilk was used to detect the normality of the samples, t test was used to analyze measurement data conformed to the normal distribution, non-parametric test was used to analyze the abnormal distribution data, and enumeration data was detected by using chi-square test. Results For patients with a clinical pathway of bronchial pneumonia, patients with severe complications and concomitant symptoms had no significant difference in mean hospitalization and sub-costs, regardless of whether they completed or entered the clinical pathway ( P >0.05). For the other two DRG patients, the difference between the average length of stay, sub-average costs, and the proportion of medications for patients who completed the clinical pathway and withdrew from or did not complete the clinical pathway was significant(P<0.05). In the severe surgical group, the length of stay and average cost for patients who completed the clinical pathway were lower than those who exited or did not enter the clinical pathway(P<0.05). Conclusions Patients with different severity of DRGs should be cautious when they are enrolled in the clinical pathway.

Mesenchymal stem cells are a kind of pluripotent stem cells that play a role in stroke treatment mainly through paracrine mechanisms. Recent studies have shown that mesenchymal stem cell-derived exosomes play an important role in reducing post-stroke injury, promoting neural repair and angiogenesis. This article describes the research progress of bone marrow mesenchymal stem cell-derived exosomes in the treatment of stroke, and investigates the therapeutic mechanism and application prospects of exosomes bioactive substances represented by microRNAs.

Micro RNAs are a kind of conserved short non-coding RNAs that regulate life activities at molecular level. Micro RNAs are active in various stages of autophagy after ischemic stroke; micro RNAs play protective or destructive roles in autophagy after stroke. Based on the autophagy process, we discuss the possible mechanism of autophagy regulated by micro RNAs through autophagy related genes or pathways, and analyze the application prospect of micro RNAs in stroke diagnosis and treatment.

Objective:To observe the effect of paeoniflorin on motor behavior and dopamine neurons of mice with Parkinson's disease (PD) by activating autophagy.Methods:Forty C57BL/6 mice were randomly divided into normal control group, model group, paeoniflorin group and paeoniflorin+3-methyl adenine (3-MA) group ( n=10). The later 3 groups were intraperitoneally injected with 1-methyl-4-phenyl-1,2,3,6-tetmhydropyridine (MPTP) at a dosage of 30 mg/(kg·d) for a consecutive 7 d to establish subacute PD models. Meanwhile, mice in the paeoniflorin group and paeoniflorin+3-MA group were intraperitoneally injected with paeoniflorin (30 mg/[kg·d]) or paeoniflorin (30 mg/[kg·d])+3-MA (2 mg/[kg·d]), respectively. Eight d after modeling, pole test and traction test were used to evaluate the locomotor ability of mice in each group. Then, the substantia nigra of the midbrain was taken; TUNEL was used to detect the nerve cell apoptosis; immunohistochemical staining was used to detect the number of tyrosine hydroxylase (TH) positive cells and the expressions of α-synuclein (α-Syn), lysosomal associated membrane protein 2A (LAMP2A) and microtubule-associated protein 1 light chain 3-II (LC3-II); Western blotting was used to detect the LAMP2A and LC3-II protein levels. Results:As compared with model group, paeoniflorin group had significantly shortened rod climbing time, significantly higher scores in traction test, significantly decreased number of apoptotic nerve cells, significantly increased number of TH-positive cells and expressions of LAMP2A and LC3-II, significantly decreased α-Syn expression, and significantly increased protein levels of LAMP2A and LC3-II ( P<0.05). The paeoniflorin+3-MA group had significantly prolonged rod climbing time, significantly lower scores in traction test, significantly increased number of apoptotic nerve cells, significantly decreased number of TH-positive cells and expressions of LAMP2A and LC3-II, significantly increased expression of α-Syn, and significantly decreased protein levels of LAMP2A and LC3-II as compared with the paeoniflorin group ( P<0.05). Conclusion:Paeoniflorin can improve dyskinesia in PD mice by inducing autophagy to remove α-Syn and protect dopaminergic neurons.

BACKGROUND:The distribution of horizontal pressure in adolescent idiopathic scoliosis can be used to evaluate the coronal imbalance.Currently,there are no reports on the characteristics of coronal pressure distribution and its correlation with coronal imbalance. OBJECTIVE:To explore the correlation between coronal pressure variation and coronal imbalance in adolescent idiopathic scoliosis patients. METHODS:A total of 39 adolescent idiopathic scoliosis patients who met the inclusion and exclusion criteria in Lianyungang First People's Hospital from March 2021 to June 2022 were selected as the adolescent idiopathic scoliosis group,and 30 matched healthy volunteers were recruited from the outpatient department as the control group.The horizontal position pressure,folding position pressure,coefficient of variation,and global and trunk pressure variation were measured by the TBED Postural Couch evaluation system.In the adolescent idiopathic scoliosis group,full-length spine radiographs were taken to measure Cobb angle,coronal balance,apical vertebral deviation and Nash-Moe rotation.The characteristics of coronal pressure variation and its correlation with coronal imbalance were analyzed. RESULTS AND CONCLUSION:(1)Compared with the control group,there was no statistically significant difference in the horizontal position pressure and folding position pressure in the adolescent idiopathic scoliosis group(P>0.05),but the global pressure variation and coefficient of variation were significantly increased(all P<0.05).(2)There were differences in both sides of the trunk of the adolescent idiopathic scoliosis group and the control group(P<0.05),and the convex side pressure variation in the adolescent idiopathic scoliosis group was higher than the concave side pressure variation in the left and right side pressure variation in the control group(all P<0.05).(3)The variation of the convex side pressure of the trunk in adolescent idiopathic scoliosis patients was positively correlated with coronal balance intensity(r=0.692,P<0.05),moderately positively correlated with Cobb angle and apical vertebral deviation(r=0.499,0.595,all P<0.05),and weakly correlated with Nash-Moe grade(r=0.377,P<0.05).The variation of the concave side pressure of the trunk was moderately positively correlated with coronal balance(r=0.410,P<0.05),and the rest was weakly correlated or not correlated(P>0.05).(4)These findings indicate that pressure variation may be used as an adjoint assessment tool in patients with mild to moderate scoliosis.

Objective:To explore the effect of Baduanjin on gait parameters and serum nerve growth factor in Parkinson disease (PD) patients with freezing of gait(FOG).Methods:From December 2021 to December 2022, thirty-eight PD patients with FOG who met the inclusion and exclusion criteria were randomly divided into observation group ( n=18) and control group ( n=20) by random number table.The patients in both two groups received 4 weeks of drug therapy combined with basic rehabilitation treatment respectively, and the patients in observation group received additional Baduanjin training.Efficacy was evaluated 1 day before intervention and after 4 weeks of intervention through unified Parkinson's disease rating scale-Ⅱ(UPDRS-Ⅱ) item 14, freezing of gait questionnaire (FOGQ), gait starting time, gait cycle, stride length, dynamic plantar peak pressure and average pressure, while the levels of brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor(GDNF) in peripheral blood of patients were tested.SPSS 23.0 software was used to conduct Chi-square test, paired t-test, independent sample t-test and Mann-Whitney U test. Results:Before treatment, there were no significant differences in score of UPDRS-Ⅱ item 14, FOGQ score, gait starting time, gait cycle, stride length, dynamic planar peak pressure, average pressure, peripheral blood BDNF level and GDNF level between the two groups ( t=-0.542, 0.562, 0.490, 0.674, 0.440, 0.606, -0.835, -0.873, -0.250, all P>0.05). After treatment, compared with the control group, dynamic plantar peak pressure (control group (14.26±3.23) N/cm 2, observation group (11.40±4.13) N/cm 2, t=-2.389, P=0.022) and plantar average pressure (control group (3.34±0.72) N/cm 2, observation group (2.79±0.81) N/cm 2, t=-2.209, P=0.034) of the observation group were significantly decreased (both P<0.05). There were no significant differences in UPDRS-Ⅱ item 14, FOGQ score, gait starting time, gait cycle, stride length, BDNF and GDNF concentrations in peripheral blood between the two groups after treatment (all P>0.05). The difference between pre-treatment and post-treatment of FOGQ score (control group 1.00 (0.00, 1.00) , observation group 2.00 (0.75, 3.00), Z=-2.547, P=0.011), gait starting time (control group -1.04 (-1.86, -0.47)s, observation group -2.34 (-3.41, -1.03) s, Z=-2.280, P=0.023), gait cycle (control group 0.29 (0.08, 0.58)s, observation group 0.35 (0.16, 1.00) s, Z=-2.748, P=0.006), stride length(control group 0.19 (0.14, 0.24) m, observation group 0.26 (0.23, 0.38)m, Z=-1.360, P=0.005), the dynamic plantar peak pressure (control group -4.11 (-5.87, -2.57) N/cm 2, observation group -8.44 (-10.12, -4.81) N/cm 2, Z=-3.333, P=0.001) and average pressure (control group -0.55 (-1.00, -0.03) N/cm 2, observation group -1.11 (-1.51, -0.66) N/cm 2, Z=-2.062, P=0.009) in the observation group were better than those in the control group.After treatment, the BDNF level in peripheral blood in observation group was higher than before treatment( t=-2.315, P=0.033). Conclusion:Baduanjin can improve frozen gait score and gait parameters in PD patients with FOG, which may be related to the increase of peripheral blood BDNF.

ObjectiveTo explore the therapeutic effect and mechanism of intermittent theta burst transcranial magnetic stimulation (iTBS) on non-fluent aphasia after stroke. MethodsFrom August, 2021 to August, 2022, 50 patients with non-fluent aphasia after stroke in the First People's Hospital of Lianyungang were randomly divided into sham stimulation group (n = 25) and iTBS group (n = 25). Both groups accepted speach training. iTBS group accepted iTBS, and the sham stimulation group received sham iTBS, for four weeks. The serum brain-derived neurotrophic factor (BDNF) was measured, and they were assessed by China Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) and Boston Diagnostic Aphasia Examination before and after treatment. ResultsTwo cases in the sham stimulation group and three cases in iTBS group dropped down. The BDNF level, and listen and understand, repeat, name, read aloud, and total score of CRRCAE improved in two groups after treatment (|t| > 5.012, P < 0.001); and they were better in iTBS group than in the sham stimulation group (|t| > 3.968, P < 0.001). The total effective rate was more in iTBS group than in the sham stimulation group (χ² = 8.835, P < 0.05). ConclusioniTBS can improve speech function in patients with non-fluent aphasia after stroke, which may associate with the promotion of BDNF.
