BACKGROUND:The biomechanical analysis of scoliosis cases is limited,with only independent analysis focusing on the spine or lower limbs,thus lacking a comprehensive evaluation of the multidimensional body.As a result,it becomes challenging to reflect the movement relationship between the trunk and lower limbs during daily activities,which hinders comprehensive clinical treatment guidance. OBJECTIVE:To explore the relationship between different segments of the spine and the kinematics/kinetics of the lower limbs during gait activities by measuring spinal kinematics in scoliosis patients,to provide a comprehensive and multi-level assessment of the biomechanical differences between scoliosis patients and the normal population,consequently offering evidence-based guidance for the prevention and treatment of scoliosis. METHODS:A cross-sectional study was conducted from July 2020 to June 2021 at the Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine in Fuzhou University City.A total of 28 scoliosis patients and 28 normal individuals in the same age group were included.Three-dimensional motion capture system was used to capture gait kinematic data at a sampling frequency of 100 Hz.Two force plates(AMTI 400600,sampling frequency 1 500 Hz)were embedded in a 10-meter-long 2.4-meter-wide level ground walkway(with an effective data collection length of 4 m)to collect kinetic data.The differences in spatial-temporal parameters,kinematics,and kinetics of gait between the two groups were compared.Immediately after inclusion,all subjects underwent full spinal X-ray measurements to compare the differences between the scoliosis and normal groups. RESULTS AND CONCLUSION:(1)Patients with scoliosis exhibited reduced relative rotational range of motion between the shoulder and trunk,as well as between the thorax and pelvis,compared to the normal group(P<0.05).However,the rotational range of motion in the pelvis was larger in patients with scoliosis compared to the normal group(P<0.05).(2)Patients with scoliosis showed decreased range of motion in the hip and knee joints,as well as reduced peak torque in hip joint flexion and extension,and lower peak values of ground reaction forces in the concave and convex directions,in comparison to the normal group(P<0.05).(3)Patients with scoliosis demonstrated greater asymmetry indices in knee joint range of motion,relative rotational range of motion between the shoulder and trunk,and between the thorax and pelvis,when compared to the normal group(P<0.05).(4)These findings illustrate a rigid movement pattern among the shoulder,thorax,and pelvis in patients with scoliosis during level walking.There is a reduction in range of motion in the hip and knee joints,as well as decreased peak torque values in hip joint flexion and extension,and ground reaction forces in the concave and convex directions.These characteristics can serve as foundational elements for assessing rehabilitation and developing treatment plans.

BACKGROUND: Molecular subtyping is an essential complementarity after pathological analyses for targeted therapy. This study aimed to investigate the consistency of next-generation sequencing (NGS) results between circulating tumor DNA (ctDNA)-based and tissue-based in non-small cell lung cancer (NSCLC) and identify the patient characteristics that favor ctDNA testing. METHODS: Patients who diagnosed with NSCLC and received both ctDNA- and cancer tissue-based NGS before surgery or systemic treatment in Lung Cancer Center, Sichuan University West China Hospital between December 2017 and August 2022 were enrolled. A 425-cancer panel with a HiSeq 4000 NGS platform was used for NGS. The unweighted Cohen's kappa coefficient was employed to discriminate the high-concordance group from the low-concordance group with a cutoff value of 0.6. Six machine learning models were used to identify patient characteristics that relate to high concordance between ctDNA-based and tissue-based NGS. RESULTS: A total of 85 patients were enrolled, of which 22.4% (19/85) had stage III disease and 56.5% (48/85) had stage IV disease. Forty-four patients (51.8%) showed consistent gene mutation types between ctDNA-based and tissue-based NGS, while one patient (1.2%) tested negative in both approaches. Patients with advanced diseases and metastases to other organs would be suitable for the ctDNA-based NGS, and the generalized linear model showed that T stage, M stage, and tumor mutation burden were the critical discriminators to predict the consistency of results between ctDNA-based and tissue-based NGS. CONCLUSION ctDNA-based NGS showed comparable detection performance in the targeted gene mutations compared with tissue-based NGS, and it could be considered in advanced or metastatic NSCLC.

Objective To explore the detection trend of vaginal intraepithelial neoplasia(VaIN)of lower genital tract from 2013 to 2015. Methods A retrospective analysis was undertaken of colposcopy-directed biopsy of cervical, vaginal and vulvar intraepithelial neoplasia lesions include cervical intraepithelial neoplasia (CIN), VaIN and vulvar intraepithelial neoplasia (VIN) in Obstetrics and Gynecology Hospital of Fudan University from January 2013 to December 2015. Results (1) Overall data of CIN, VaIN and VIN:a total of 16732 cases were diagnosed of lower genital intraepithelial neoplasia in 3 years, accounting for 23.20% (16732/72128) of total colposcopy-directed biopsy cases. Among them, CIN, VaIN and VIN accounted for 19.48%(14053/72128), 2.67%(1923/72128), 1.05%(756/72128) of total colposcopy-directed biopsy cases of the lower genital tract, 83.99%(14053/16732), 11.49%(1923/16732), 4.52%(756/16732) of total lower genital intraepithelial neoplasia, respectively. (2) Annual data of CIN, VaIN and VIN from 2013 to 2015. The annual proportion of CIN in all intraepithelial neoplasia of lower gential tract was basically stable, consisting of 86.02%(3955/4598),83.25%(4795/5760) and 83.20%(5303/6374), respectively. The annual proportion of VaIN was gradually increasing, consisting of 8.09% (372/4598), 12.45%(717/5760) and 13.08%(834/6374), respectively. The annual proportion of VIN was gradually decreasing, consisting of 5.89% (271/4598), 4.31% (248/5760) and 3.72% (237/6374), respectively. Conclusion The increasing detection of VaIN from 2013 to 2015 might correlate with the increasing attention to inspection of the entire vaginal wall.

The impact of acupuncture for the pregnancy of in vitro fertilization-embryo transfer (IVF-ET) is discussed in the paper. Nowadays there are various conclusions about the impact of acupuncture for IVF-ET, and it may result from the differences in research designs. The effect is closely related to the demographic and clinical characteristics of subjects, such as age, the diagnosis of barrenness, blood flow index of uterine spiral arteries, the cycle of IVF, etc. Besides, the efficacy is influenced by treatment based on syndrome differentiation or not, the frequency and course of acupuncture in both the treating group and the control group, etc. If more reasonable design is achieved in the further study based on them, more reliable evidence will be provided for the effect and mechanism of the pregnancy of IVF-EF by acupuncture.

Objective To study the clinical effects of the combination of the topping tongue method and the scraping tongue method in speech training after the operation of ankyloglossia with lingua apical articulation disor-der.Methods Based on the random control study design,50 cases of ankyloglossia with lingua apical articulation disorders were randomly allocated into experimental group (25 cases)and control group (25cases).Patients of ex-perimental group were given routine speech training with the topping tongue and scraping tongue methods.Patients of control group were given routine speech training,and data of voice intelligibility of two groups of patients were collected at the time before speech training and after 3 courses of speech training.Results The voice intelligibility of two groups of patients before speech training had no statistically significant differences(t =0.726,P >0.05 ).But the voice intelligibility of the patients after 3 courses of speech training in both groups was obviously improved. There were statistically significant differences(P <0.001).Patients in the experimental group had a higher voice in-telligibility score assessed after 3 courses of speech training than the control group.After treatment,the voice intel-ligibility of the patients in experimental group increased from 37.91% to 87.69%.The voice intelligibility of the pa-tients in the control group increased from 37.69% to 72.99%.There were statistically significant differences(P <0.001).Conclusion The combination of the topping tongue and scraping tongue methods can improve the speech intelligi-bility for patients after operation of ankyloglossia and promote rehabilitation training of the lingua- apical articulation.

Aim To study the effect of artesunate on immuno-injured hepatic fibrosis induced by bovine ser-um albumin in rat model and the effect of artesunate on hepatic stellate cells ( HSCs ) proliferation, so as to provide experimental evidence for clinical application of artesunate and the treatment of hepatic fibrosis. Methods The model of immuno-injured hepatic fibro-sis induced by bovine serum albumin was established in Wistar rats. Rats were randomly divided into 5 groups:normal group, model group, low dose of arte-sunate, middle dose of artesunate and high dose of ar-tesunate. Drugs were given to the corresponding thera-peutic groups, and then were continued once a day for two months. Distilled water was given to the rats of normal and model groups according to the same meth-od. Liver tissues were used for measuring the content of collagen, the rat serum activities of albumin( Alb) , alanine aminotransferase ( ALT ) and aspartate amin-otransferase(AST). Liver tissue’ s pathological chan-ges were observed by HE and collagen staining. Isola-ted and cultured rat primary HSCs in the flask for 10 days to make cells activated, MTT assay was used to detect rate of cellular proliferation; concentration of hydroxyproline in supernatant was detected by digestive method; the expression of p53 was investigated by Western blot and RT-PCR. Results Serum levels of Alb in model group were significantly lower ( P <0. 05 ) , and levels of ALT and AST in model group were significantly higher ( P <0. 05 ) compared with normal group. Levels of AST in low, middle and high dose groups(3. 2, 9. 6, 28. 8 mg·kg-1 ) were signifi-cantly lower(P <0. 05) compared with model group, and levels of ALT in high dose groups were significant-ly lower(P<0. 01) compared with model group. The contents of collagen in model groups were significantly higher(P<0. 01) compared with normal group, while the contents of collagen in therapy groups significantly decreased ( P < 0. 05 ) compared with model group. Activated HSCs treated with various concentrations of artesunate (150, 175, 200 μmol·L-1 ) were inhibi-ted on dose and time-effect relationships. Production/secretion of hydroxyproline decreased after HSCs was treated by artesunate for 24 h; the expression of p53 was up-regulated showed by Western blot and RT-PCR in artesunate treated cells. Conclusion Artesunate brings about anti-fibrosis in vitro and in vivo by increas-ing the expression of p53 .
