Based on the theory of the rise and fall of qi-blood in meridians, Professor GAO Yu-chun harmonizes the qi-blood and yin-yang for diagnosis and treatment of hypertersion from liver, spleen and kidney. With reference of the academic idea of“Preventive Acupuncture”, he investigated the qi and blood, treated diseases in the upper part by managing the lower part, pay attention to the syndrome differentiation of excess and deficiency, the different of acupoint property, and the treatment of acupuncture or moxibustion. Thus, through balancing yin and yang, the qi and blood are regulated to reach the therapeutic aim of“yin and yang in equilibrium”.

Objective To investigate the relationships of suicide risk and its associated risk factors in adult patients with epilepsy.Methods All 211 adult patients with epilepsy from the epilepsy clinic of the Second Affiliated Hospital,Zhejiang University School of Medicine,were enrolled to evaluate the presence of suicide risk and depressive disorder by using the suicide module and the depressive disorder module of the Mini International Neuropsychiatric Interview (MINI).Demographic variables for age,gender,employment status,marital status,years of education,and seizure factors for age of onset,types of seizure,seizure frequency and epilepsy duration,result of MRI and types of antiepileptic drugs were also recorded.We compared the differences of risk factors between the two groups with or without suicide risk and investigated the relationships between the depressive disorder and suicide risk.Results The suicide risk of the patients was 21.3％ (45/211),and 17.1％ (36/211) of the patients had depressive disorder.The suicide risk of the epilepsy patients associated with depressive disorder was 75.0％ (27/36),and the suicide risk of the epilepsy patients associated with no depressive disorder was 10.3％ (18/175).There was statistical difference between the two groups (x2 =74.525,P ＜ 0.01).About 60.0％ (27/45) of the patients with suicide risk was accompanied with depressive disorder.As suicide risk increased,the proportion of concurrent depressive disorder elevated.There was significant statistical difference in the rates of depressive disorder among the different suicide risk groups.Conclusions The patients with epilepsy have suicide risk.The suicide risk is higher in patients with depressive disorder.

Objective To compare the long-term efficacy between laparoscopic liver resection and open liver resection to treat small hepatocellular carcinoma.Methods The clinical data of 52 patients with small hepatocellular carcinoma treated from August 2011 to November 2012 were reviewed.Twenty patients underwent laparoscopic liver resection (the laparoscopic group),while the remaining 32 patients underwent open liver resection (the laparotomy group).The preoperative,postoperative and overall survival data between the two groups were compared.Results The data between the two groups before surgery were comparable (all P ＞ 0.05).The differences in tumor size and pathologic type between the two groups did not reach statistical significance (t =1.087,x2 =0.738,all P ＞ 0.05).However,the length of hospital stay in the laparoscopic group was significantly shorter than in the laparotomy group (t =3.363,P ＜ 0.05).Post-procedural complications occurred in no patients in the laparoscopic group,but in 8 patients in the laparotomy group (x2 =5.909,P ＜ 0.05).The cumulative survival rates in the two groups were not statistically signifi cant (P ＞ 0.05),but the recurrence-free survival of the laparoscopic group was significantly longer than the laparotomy group (P ＜ 0.05).The postoperative 1-year disease-free survival was not significantly different (P ＞ 0.05),though the 3-and 5-year recurrence-free survival rates were significantly different (all P ＜ 0.05).Conclusion The long-term overall survival rate of laparoscopic treatment for small liver cancer was similar to open operation,but the recurrence free survival rate was greatly improved.

Objective:To observe the morphological characteristics of L 4, 5 facet joints in patients with degenerative lumbar spondylolisthesis (DLS) of different spinopelvic types based on Roussouly classification. Methods:We retrospectively analyzed 142 patients with DLS who visited the department of orthopaedics in the Affiliated Hospital of Southwest Medical University from August 2018 to May 2022. There were 33 males aged 65.0±10.7 years and 109 females aged 61.8±9.6 years. The following morphological parameters of the L 4, 5 facet joint were measured on the CT images: facet joint angle (FJA), pedicle facet angle (PFA), facet joint tropism (FT) and facet joint osteoarthritis (OA) degree; the sacral slope (SS), lumbar lordosis (LL) and percentage of L 4 slip distance (SDP) were measured on preoperative standing neutral lumbar radiographs. According to the Roussouly classification, the patients were divided into four groups (type I, type II, type III, and type IV). The differences of morphological parameters of the facet joints and SDP were compared among the four groups, and the correlation between the FJA and PFA was analyzed. Results:There were 142 patients, including 28 type I, 50 type II, 43 type III, and 21 type IV according to the Roussouly classification. The SDPs of type I, type II, type III, and type IV were 19.1%±3.4%, 18.6%±3.9%, 21.7%±3.9%, 25.0%±2.4%, respectively. Except for types I and II, there were statistically significant differences in pairwise comparison among all other types ( P<0.05). The FJAs in type I and type II (31.4°±6.3°, 35.2°±6.8°) were larger than those in type III (28.4°±5.6°) and type IV (23.4°±4.5°), and the FJA in type III was larger than that in type IV. Conversely, the FJA in type I was smaller than that in type II. These differences were statistically significant ( P<0.05). The PFAs in type I and type II (113.9°±4.9°, 111.3°±5.6°) were smaller than those in type III (116.3°±4.4°) and type IV (121.8°±3.5°), and the PFA in type III was smaller than that in type IV, while, the PFA in type I was larger than that in type II. These differences were statistically significant ( P<0.05). The degree of OA in both type I and type II was lower than that in type III and type IV, with statistically significant differences ( P<0.05). However, there were no statistically significant differences in the degree of OA between type I and type II and between type III and type IV ( P> 0.05). Additionally, there were no statistically significant differences ( F=0.40, P=0.752) in the FT values among type I, type II, type III, and type IV (5.8°±2.3°, 5.6°±2.4°, 6.1°±1.8°, 5.9°±1.9°). Pearson correlation analysis showed that FJA was negatively correlated with PFA ( r=-0.68, P<0.001). Conclusion:In the slip segment of DLS, the facet joint morphology was part of the joint configuration in different spinopelvic types, not just the result of joint remodeling after DLS. Morphological characteristics of the facet joints and DLS interacted with each other.

Objective:To delineate the morphological features of pedicle-facet joints in lumbar spondylolysis patients, correlating these with spinopelvic parameters to explore their mechanisms and clinical implications.Methods:This study enrolled 121 patients with L 5 spondylolysis (IS group), 108 with L 4, 5 degenerative spondylolisthesis (DS group), and 100 with normal L 4, 5 but L 5S 1 lumbar disc herniation (NL group), who underwent radiography and multislice spiral CT from May 2020 to January 2023. Parameters including vertebral slip percentage (SP) and spinopelvic alignments, such as sacral slope and lumbar lordosis, were quantified using standing lateral lumbar radiographs. Morphological parameters of the L 4 and L 5 facet joints were measured on 3D reconstructed lumbar CT images, including the facet joint angle (FJA), pedicle-facet joint angle (PFA), facet joint osteoarthritis (OA), and facet joint tropism (FT). Results:The analysis revealed significant variances in SS and LL among the groups ( F=21.910, P<0.001; F=22.439, P<0.001). The IS group exhibited the highest SS and LL, followed by the DS and NL groups. Morphological assessments showed the largest L 4 FJA in the IS group, with progressive decreases in the DS and NL groups ( F=344.791, P<0.001). Conversely, L 4 PFA was greatest in the DS group ( F=193.725, P<0.001). Notably, L 4 OA was markedly more severe in the DS group compared to IS and NL groups ( H=467.925, P<0.001), with no significant disparity between IS and NL groups ( P>0.05). Correlation analyses within each cohort highlighted a negative association of sacral slope and lumbar lordosis with facet joint angles, yet a positive correlation with pedicle-facet joint angles both with statistical significance ( P<0.05). Furthermore, L 4 facet joint angles were consistently smaller than those at L 5, and L 4 pedicle-facet joint angles were larger than L 5 ( P<0.05). Osteoarthritis at L 5 was more pronounced in the IS group compared to L 4 ( Z=7.043, P<0.001), a trend inversely observed in the DS group ( Z=11.868, P<0.001), while the NL group showed no significant osteoarthritic variance between levels ( Z=0.556, P=0.578). Conclusion:Patients with lumbar spondylolysis demonstrate elevated sacral slope and lumbar lordosis, indicative of increased localized biomechanical stress in the lumbar spine. These alterations in the morphology of the pedicle-facet joints highlight the distinctive structural adaptations and potential strain distributions within this cohort.

Objective: To understand the current situation of academic burnout among primary and middle school students and to explore its associated factors, so as to provide a scientific guidance and preventing and amelioration academic burnout among primary and middle school students. Methods: Between September and October 2023, a total of 10 474 primary and middle school students residing in Wuxi City participated in a questionnaire survey and physical examination conducted through stratified cluster random sampling. Latent profile analysis was used to classify academic burnout among primary and middle school students. Furthermore, differences in the types of academic burnout among children and adolescents with varying characteristics were examined using the Chi square test. Additionally, multinomial Logistic regression analysis was utilized to identify the associated factors for academic burnout. Results: The academic burnout of primary and middle school students was divided into 4 categories:no/light academic burnout group(43.6%),physical and mental exhaustion group (32.9%), low achievement group(15.0%), high physical and mental exhaustion/high academic burnout group(8.5%). Middle and high school students, boys, not living with parents, smoking, daily screen time ≥2 hours, suffering from campus bullying, sometimes/often subjected to cyber attacks, abused by parents were more likely to have high physical and mental exhaustion/high academic alienation among primary and middle school students ( OR=1.70, 1.42, 1.56, 1.56, 2.31, 1.48, 2.94, 3.03, 5.94, 2.08, P <0.01). Conclusions The phenomenon of academic burnout among primary and middle school students is prominent. And targeted intervention measures shoould be actively taken to prevent and reduce the occurrence of academic burnout among primary and middle school students.

Objective: Based on spinopelvic parameters and biomechanical principles, the pedicle-facet joint (PFJ) morphological characteristics of isthmic and degenerative spondylolisthesis were analyzed, and the mechanism of their onset and progression was discussed. Methods: This retrospective cross-sectional study included 194 patients with L5 spondylolysis or L5–S1 low-grade isthmic spondylolisthesis (IS group), 172 patients with L4–5 degenerative spondylolisthesis (DS group), and 366 patients with nonlumbar spondylolysis (NL group). The spinopelvic parameters and PFJ morphological parameters of the patients were measured, the differences in these parameters among and within the 3 groups were compared, and the correlations were analyzed. Results: Sacral slope (SS) and lumbar lordosis (LL) were the highest in the IS group, the second highest in the DS group, and the lowest in the NL group. Among the 3 groups, the L4 facet joint angle (FJA) was the largest in the IS group, the second largest in the NL group, and the smallest in the DS group. The L4 pedicle-facet joint angle (PFA) was the largest in the DS group, the second largest in the IS group, and the smallest in the NL group. Pearson correlation analysis showed that within each group, SS and LL were negatively correlated with FJA and positively correlated with PFA. Conclusion This study found a correlation between the PFJ morphological characteristics of patients with lumbar spondylolisthesis and spinopelvic parameters, suggesting that the morphological characteristics of PFJs may be caused by varying stresses under different spinopelvic morphologies.
