Neurodegenerative disorders (NDDs) are prevalent chronic conditions characterized by progressive synaptic loss and pathological protein alterations. Increasing evidence suggested that mitochondrial quality control (MQC) serves as the key cellular process responsible for clearing misfolded proteins and impaired mitochondria. Herein, we provided a comprehensive analysis of the mechanisms through which MQC mediates the onset and progression of NDDs, emphasizing mitochondrial dynamic stability, the clearance of damaged mitochondria, and the generation of new mitochondria. In addition, traditional Chinese medicines (TCMs) and their active monomers targeting MQC in NDD treatment have been demonstrated. Consequently, we compiled the TCMs that show great potential in the treatment of NDDs by targeting MQC, aiming to offer novel insights and a scientific foundation for the use of MQC stabilizers in NDD prevention and treatment.

Heart failure(HF)is a highly morbid syndrome that seriously affects the physical and mental health of patients and generates an enormous socio-economic burden.In addition to cardiac myocyte oxidative stress and apoptosis,which are considered mechanisms for the development of HF,alterations in cardiac energy metabolism and pathological autophagy also contribute to cardiac abnormalities and ultimately HF.Silent information regulator 1(Sirt1)and adenosine monophosphate-activated protein kinase(AMPK)are nicotinamide adenine dinucleotide(NAD+)-dependent deacetylases and phosphorylated kinases,respectively.They play similar roles in regulating some pathological processes of the heart through regulating targets such as peroxisome proliferator-activated receptor γ coactivator 1α(PGC-1α),protein 38 mitogen-activated protein kinase(p38 MAPK),peroxisome proliferator-activated receptors(PPARs),and mammalian target of rapamycin(mTOR).We summarized the synergistic effects of Sirt1 and AMPK in the heart,and listed the traditional Chinese medicine(TCM)that exhibit cardioprotective properties by modulating the Sirt1/AMPK pathway,to provide a basis for the development of Sirt1/AMPK activators or inhibitors for the treatment of HF and other cardiovascular diseases(CVDs).

In view of the difficulties and blind spots of western medicine, how to make scientific decisions to standardize the treatment of breast cancer in traditional Chinese medicine and improve the participation of traditional Chinese medicine in the treatment of breast cancer is an important focus of innovative breakthroughs in breast cancer treatment. Based on the clinical experience of Professor LIN Yi, a master of traditional Chinese medicine, and on the basis of "disease identification and syndrome differentiation", this paper summarizes and refines the status of qi and blood imbalance, accumulation of phlegm and blood stasis, viscera deficiency, and cold heat cementation in breast cancer, and further proposes the "six views" of breast cancer balanced treatment: the pathogenesis view focuses on "evil invasion due to vital qi deficiency, and the proliferation of tumors", and the pathogenesis view focuses on "cancer toxin and imbalance of yin and yang", the diagnostic view focuses on "examining the underlying factors and understanding the causes and effects", the differentiation view focuses on "balancing qi, blood, yin, and yang to achieve harmony", the therapeutic view focuses on "supporting vital qi and eliminating evil, and considering the root cause and syndromes", and the rehabilitation view focuses on "adjusting balance to maintain a stable state". We are committed to holistic syndrome differentiation and treatment, balancing yin, yang, qi, and blood, thereby harmonizing the internal environment of the human body, and mobilizing the immune and rehabilitation functions of the body.

Objective:To evaluate the safety and effectiveness for the treatment of totally robotic fundoplication.Methods:A retrospective analysis was conducted on the clinical data of 21 patients with gastroesophageal reflux disease (GERD) who underwent unassisted totally robotic fundoplication at the Second Department of General Surgery, Yan'an Hospital Affiliated to Kunming Medical University from Aug 2023 to Jan 2024. The postoperative outcomes were evaluated using SF-36, GERD-Q, and NRS scoring indicators.Results:All 21 patients successfully underwent the surgery. The robotic surgery time was (99±41) minutes, with precise intraoperative anatomy and insignificant blood loss of (1.7±1.4) ml. There were no intraoperative or postoperative complications, and no conversions to open surgery . Postoperative recovery of bowel function was rapid (11.71±3.33) hours, with minimal postoperative pain (NRS score of 1.67±0.48).The postoperative hospital stay was short (3.86±2.90) days, and patient satisfaction was high, SF-36 score of (80.90±1.14);The symptoms of reflux after surgery was significantly reduced.Postoperative GERD-Q score of (4.38±1.69) significantly lower than the preoperative score of (13.90±2.07).Conclusion:Totally robotic fundoplication provides clear view of intraoperative anatomical structures, rapid postoperative recovery, minimal pain, and effective anti-reflux outcomes.

Objective:To elucidate the clinical and genetic characteristics of PLA2G6-related parkinsonism. Methods:The clinical, imaging and genetic data of 6 patients with PLA2G6-related parkinsonism admitted to Peking Union Medical College Hospital from January 2015 to December 2022 were retrospectively collected and analyzed. The prognosis was followed up through phone call. Results:There were 3 male and 3 female patients, and the age of disease onset was (24.3±5.4) years. Phenotypically, 5 of them had dystonia-parkinsonism (DP) with obvious atrophy of cerebellum and 1 presented as early-onset Parkinson′s disease (EOPD) with no brain structural abnormality. Only 1 patient presented with abnormal brain iron deposition. All of the patients were partially responsive to levodopa. Three cases underwent levodopa challenge test with the objective levodopa responsiveness varied from 10.3% and 10.6% in 2 DP patients, to 77.0% in 1 EOPD patient. Levodopa-induced dyskinesias were present in 4 of them, and all appeared within the first year since the initiation of dopaminergic treatment. Two patients underwent bilateral deep brain stimulation (DBS) of subthalamic nucleus and globus pallidus internus respectively, albeit revealed poor outcome. Genetically, 8 PLA2G6 variants were identified. Two of them were found to be novel (c.1973A>G and exon2 heterozygous deletion), and the most frequent variant was the c.991G>T mutation which was detected in 4 patients. Conclusions:The phenotype of PLA2G6-related parkinsonism is complex. Cerebellar atrophy is a frequent magnetic resonance imaging feature. Levodopa responsiveness tends to depend on the clinical phenotype, and EOPD is better than DP. DBS might not be promising in DP patients with obvious cerebral atrophy. The c.991G>T mutation is the most frequent mutation, suggesting a common founder effect.

Objective:To explore the spatial and temporal distribution patterns of emerging snail-infested sites in different environmental types in Yunnan Province.Methods:The data of snail-infested sites in Yunnan Province from 1950 to 2014 (from Yunnan Institute for Endemic Diseases Control and Prevention), were collected and sorted out, a spatial and temporal database on the distribution of emerging snail-infested sites were established, and the changes in the spatial and temporal distribution of emerging snail-infested sites in different environments types (ditches, tangerines, paddy fields, dry land, beaches and other environments) were studied by using spatial autocorrelation analysis and scanning statistics analysis.Results:From 1950 to 2014, the annual number of emerging snail-infested sites in Yunnan Province reached a peak (1 730) in 1955 and then showed a fluctuating downward trend. From 1993 to 2014, the number of emerging snail-infested sites remained below 100, and increased to 160 and 131, respectively, in 2004 and 2013. The longest mean duration of 43.85 years was recorded for the beaches environment for emerging snail-infested sites, followed by the paddy fields environment with a mean duration of 37.01 years, and the shortest mean duration of 20.44 years for the tangerines environment. Spatial autocorrelation analysis showed that there was a positive spatial correlation between the duration of emerging snail-infested sites of different environmental types (global Moran's I ranged from 0.43 to 0.64, P < 0.05). Scanning statistics analysis showed that emerging snail-infested sites of different environmental types had spatial and temporal aggregation ( P < 0.001), with 3- 6 clusters of statistically significant aggregation detected respectively. Conclusion:The emerging snail-infested sites in different environments types in Yunnan Province have spatial and temporal aggregation, and it is necessary to strengthen monitoring and prevention and control of the aggregation areas of different environment types to prevent further spread of the snail.

Objective:To assess the effects of noninvasive positive pressure ventilation on premature infants' cardiac function using Tei index combined with corrected QT dispersion (QTcd) and B- type natriuretic peptide (BNP).Methods:This prospective study involved premature infants from 28 to 32 weeks of gestational age diagnosed with respiratory distress syndrome (RDS) and treated with noninvasive positive pressure ventilation in the Neonatal Intensive Care Unit of Xuzhou Central Hospital from December 2017 to December 2020. According to the mean airway pressure (MAP) during noninvasive positive pressure ventilation, the patients were divided into the low-pressure group (≤6 cmH 2O, 1 cmH 2O=0.098 kPa), medium-pressure group (>6-<9 cmH 2O), and high-pressure group (≥9 cmH 2O). The right ventricular Tei index, QTcd, and blood BNP were monitored during the first 2 h of noninvasive positive pressure ventilation and 12 h after continuous ventilation with stable MAP. Chi-square test, one-way analysis of variance, paired t-test, and Pearson product-moment correlation coefficient were adopted for statistical analysis. Results:Totally 178 premature infants were enrolled, including 75 in the low-pressure, 62 in the medium-pressure, and 41 in the high-pressure group. After continuous ventilation with stable MAP for 12 h, the right ventricle Tei index and QTcd in the high-pressure group were higher than those in the medium- and low-pressure group [Tei index: (0.38±0.05) vs (0.33±0.04) and (0.33±0.04), F=29.18; QTcd: (27.6±4.2) vs (22.8±4.4) and (22.2±4.2) ms, F=23.26, all P<0.001], and the comparison between the medium- and the low-pressure group did not differ significantly. No significant difference was observed in blood BNP levels among the three groups ( F=1.33, P=0.267). The right ventricle Tei index and QTcd increased in the high-pressure group after continuous ventilation with stable MAP for 12 h as compared with those within the first 2 h of noninvasive positive pressure ventilation [Tei index: (0.38±0.05) vs (0.34±0.04), t=－6.61; QTcd: (27.6±4.2) vs (23.4±4.4) ms, t=－5.06, all P<0.001]. However, the figures did not change significantly in the medium- or the low-pressure group (all P>0.05). There were no significant changes in blood BNP in the three groups (all P>0.05). The right ventricle Tei index and QTcd were moderately positively correlated with MAP ( r=0.56 and 0.50, both P<0.001). Conclusions:For the premature infants with RDS, noninvasive positive pressure ventilation has no significant effect on the cardiac function when MAP is less than 9 cmH 2O, but would have a certain effect on the right ventricular function when used at higher pressure (MAP≥9 cmH 2O) and for longer time (>12 h).

Objective:To compare left and right ventricular Tei indexes and to determine the reference range in newborns of different gestational age (GA) and birth weight (BW).Methods:From February 2019 to June 2021, newborns admitted to the Neonatal Intensive Care Unit of our hospital were enrolled. Tei indexes were measured and calculated during 24 h~7 d after birth and reexamined 1~2 weeks later in some of the newborns. The newborns were assigned into <32 w group, 32~36 w group and ≥ 37 w group according to their GA, < 1 500 g group, 1 500~2 499 g group and ≥2 500 g group according to their BW, and early newborn group (1~7 d) and late newborn group (>7 d) according to their age of evaluation. The data were analyzed using t test, one-way analysis of variance (ANOVA) and correlation analysis with SPSS 20.0 statistical software. Results:A total of 128 cases were included. 42 cases in <32 w group, 43 in 32~36 w group and 43 in ≥37 w group. 42 cases in <1 500 g group, 42 in 1 500 ~ 2 499 g group and 44 in ≥2 500 g group. Tei indexes were reexamined after 7 d of age in 63 preterm infants and in 31 full-term infants. The left and right ventricular Tei indexes of the ≥37 w group were less than the 32~36 w group and the <32 w group in early newborns (left ventricular: 0.382±0.069 vs. 0.431±0.069 and 0.439±0.060, right ventricular: 0.373±0.038 vs. 0.431±0.035 and 0.452±0.064); the right ventricular Tei index of the 32~36 w group was significantly less than the <32 w group ( P<0.05). No significant differences existed in the left ventricular Tei index between the 32 ~ 36 w group and the < 32 w group ( P>0.05). The left and right ventricular Tei indexes of the ≥2 500 g group were significantly less than the 1 500~2 499 g group and the <1 500 g group (left ventricular: 0.385±0.069 vs. 0.434±0.067 and 0.434±0.064, right ventricular: 0.376±0.039 vs. 0.431±0.043 and 0.450±0.061) ( P<0.05).No significant differences existed between the 1 500~2 499 g group and the <1 500 g group ( P>0.05). No significant differences existed in the left and right ventricular Tei indexes between the late newborn group and early newborn group ( P>0.05). For early newborns (1~7 d of age), the reference range of Tei index gradually decreased along with the increase of GA and BW. Conclusions:The left and right ventricular Tei indexes of full-term infants and infants with BW ≥2 500 g are less than preterm and low birth weight infants. The reference range of Tei index in early newborns shows negative correlation with GA and BW.

Objective:To investigate the effects of non-invasive positive pressure ventilation (NPPV) on plasma B-type natriuretic peptide (BNP) level and Tei index of right ventricle in preterm infants.Methods:Premature infants of gestational age<34 weeks with respiratory distress syndrome who were admitted in Neonatal Intensive Care Unit of Xuzhou Central Hospital and requiring for NPPV from December 2018 to October 2020, were enrolled in the study. Patients were randomly divided into two groups 46 patients received nasal continuous positive airway pressure ventilation (NCPAP group) and 49 patients received bi-level positive airway pressure ventilation (BiPAP group); 42 preterm infants of gestational age<34 weeks and without NPPV were selected as the control group. The plasma BNP, Tei index of right ventricle, mean airway pressure and oxygen index at 0-12 h and 48-60 h after NPPV were monitored in NCPAP group and BiPAP group. The plasma BNP and Tei index of right ventricle at 0-12 h and 48-60 h after admission were monitored in the control group. SPSS 20.0 statistical software was used for data analysis.Results:(1)The plasma BNP and Tei index of right ventricle at 48-60 h after NPPV were significantly higher than those at 0-12 h after NPPV in NCPAP group and BiPAP group [NCPAP group: (287.5±155.5) vs. (179.9±102.3) ng/L, (0.43±0.08) vs. (0.38±0.06); BiPAP group: (303.1±135.4) vs. (186.5±95.6) ng/L, (0.45±0.08) vs. (0.39±0.06); t=6.00, 3.34, 7.47, 4.48; all P<0.05]. There were no significant differences in the plasma BNP and Tei index of right ventricle at 48-60 h and 0-12 h after admission in the control group [(181.9±86.8) vs. (169.5±78.9) ng/L, (0.34±0.05) vs. (0.36±0.05); t=0.83, -1.59; all P>0.05].(2) There were no significant differences in the plasma BNP and Tei index of right ventricle at 48-60 h after NPPV between NCPAP group-and BiPAP group (all P>0.05), but they were significantly higher than those in control group at 48-60 h after admission(all P<0.05). (3)The mean airway pressure and oxygen index at 48-60 h after NPPV in NCPAP group and BiPAP group showed a decrease trend compared to those at 0-12 h after NPPV, but the differences were not significant [NCPAP group: (6.8±1.2) vs. (7.0±1.3) cmH 2O(1 cmH 2O=0.098 kPa), (5.7±2.1) vs. (6.1±2.3); BiPAP group: (7.0±1.3) vs. (7.2±1.2) cmH 2O, (5.5±2.0) vs. (5.8±2.1); t=-1.05, -0.80, -1.88, -0.67; all P>0.05]; while there were no significant differences between the two groups (all P>0.05). (4)There was a positive correlation between the plasma BNP and mean airway pressure ( r=0.48, P<0.001), but no correlation between Tei index of right ventricle and mean airway pressure ( r=0.17, P=0.119) at 48-60 h after NPPV. Conclusion:The cardiac function indexes such as plasma BNP and Tei index of right ventricle in preterm infants are increased at 48-60 h after NPPV. When mean airway pressure is the same, the effects of NCPAP and BiPAP on plasma BNP and Tei index of right ventricle in preterm infants are similar.
