Cellular force transducer plays a crucial role in normal development of the follicles,which consists of integrin,focal adhesion,signal pathways and cytoskeleton.In follicle development,cellular force transducer converts force stimulation into biochemical signal,and activates the signal pathways to make cytoskeleton respond to stimulation.This process promotes various biological functions of germ cells,such as migration,meiosis and ovulation.This review summarizes the mechanism of follicles'development from two aspects,the role of cellular force transducer in the development of follicles and the related signal pathways,so as to provide a new idea for the further study of follicle development.

Objective:To sinicize the Modified Version of Motivation Scale for Stroke Rehabilitation (MORE) based on cognitive interviewing, and test its reliability and validity.Methods:The initial Chinese version of the MORE was developed based on the Brislin model and expert analysis method. From April to May 2021, purposive sampling was used to select 22 stroke patients from Linquan People's Hospital as the research subject for three rounds of semi-structured interviews. The Chinese version of the MORE was revised based on interview results to form the final version. From June 2021 to April 2023, convenience sampling was used to select 200 stroke patients from Linquan People's Hospital for investigation, to test the reliability and validity of the scale.Results:After three rounds of semi-structured interviews, a Chinese version of the MORE consisting of 17 items was formed. The content validity index at the item level was 0.913 to 1.000, and the content validity index at the scale level was 0.921. Three common factors were extracted using the maximum variance orthogonal rotation, with a cumulative variance contribution rate of 77.318%. The Cronbach's α coefficient of the Chinese version of the MORE was 0.937, the half coefficient was 0.898, and the test-retest reliability was 0.911.Conclusions:The understanding of the Chinese version of the MORE by stroke patients is comprehensively understood through cognitive interviewing. The reliability and validity test finds that the Chinese version of the MORE is an effective and reliable scale for evaluating the rehabilitation motivation of stroke patients, providing a reference basis for analyzing the influencing factors of rehabilitation motivation of stroke patients and formulating prevention and intervention measures.

Objective:To investigate the impact of sarcopenia on the short-term outcomes and long-term prognosis in cervical cancer patients undergoing concurrent chemoradiotherapy (CCRT).Methods:A total of 410 cervical cancer patients who received CCRT in Henan Provincial People′s Hospital between January 2017 and December 2021 were prospectively enrolled in this study. They were divided into the sarcopenia and non-sarcopenia groups based on the body muscle content measured using bioelectrical impedance analysis. Short-term outcomes were assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST), and acute adverse reactions were assessed based on the toxicity criteria of the Radiation Therapy Oncology Group (RTOG). CCRT termination or prolonged treatment associated with various acute adverse reactions were recorded. All patients were followed up with overall survival (OS) and progression-free survival (PFS) as endpoints. Finally, the survival rate was estimated and the association between sarcopenia and PFS was analyzed.Results:Among the patients, 152 (37.1%) had sarcopenia. Compared to the non-sarcopenia group, the sarcopenia group exhibited higher incidences of grade 2 or above acute adverse reactions in the lower gastrointestinal and hematological systems, CCRT termination, or prolonged treatment. In the non-sarcopenia group, 27 deaths were recorded, with an OS of 30 (18-36) months, a 3-year OS rate of 88.7%, and a 5-year OS rate of 85.6%. In the sarcopenia group, 23 deaths were found, with an OS of 24 (15-33) months, a 3-year OS rate of 83.8%, and a 5-year OS rate of 77.7%. There was no significant difference in survival curves between both groups ( P > 0.05). In the non-sarcopenia group, 52 cases of recurrence were recorded, with a PFS of 21 (12-33) months, a 3-year PFS rate of 77.9%, and a 5-year PFS rate of 71.0%. In the sarcopenia group, 41 cases of recurrence were found, with a PFS of 15 (10.5-24) months, a 3-year PFS rate of 69.0%, and a 5-year PFS rate of 56.5%. There was a significant difference in the PFS curves between both groups ( χ2 = 5.89, P = 0.015). Multivariate Cox regression analysis identified sarcopenia as an independent risk factor for PFS ( χ2 =4.33, P = 0.037). Conclusions:Sarcopenia increases the risks of acute adverse reactions and long-term recurrence in cervical cancer patients undergoing CCRT.

Objective:To explore the necessity and feasibility of clinical nutrition pharmacist-involved consultation, and evaluate the impact on clinical outcome.Methods:Patients who received the nutritional consultation involving pharmacists at Shanxi Bethune Hospital between 2019 and 2021 were retrospectively enrolled. Patient clinical characteristics, distribution, consultation purpose and nutrition management regimen, and clinical outcomes were collected and analyzed.Results:There was increasing utilization of nutrition pharmacist-involved consultations and referrals to pharmacy clinic over the three years. An average of 95.3% of consultation advices were accepted. Over 90% of patients who were scored 3-6 points with Nutritional Risk Screening 2002 benefited from such consultations. Patients with tumors, elderly patients, and patients with digestive system disorders showed the most benefit from nutritional consultations. The purpose of consultation was focused on the development of individualized nutritional management plans, which brought about improvement in patient's nutritional indicators.Conclusion:There is a strong demand for nutritional pharmacy consultation in large-scale comprehensive hospitals, and the standardized consultation workflow paves the way for comprehensive and individualized nutrition therapy.

Objective:To evaluate the right ventricular function in patients with dilated cardiomyopathy (DCM) by four-dimensional automatic right ventricular quantitative analysis (4D Auto RVQ), and compare with the right ventricular ejection fraction measured by cardiac magnetic resonance (CMR-RVEF), and to explore the clinical application value of 4D Auto RVQ technique in evaluating the right ventricular function of patients with DCM.Methods:A prospective study was conducted to select 52 patients with DCM who were treated in Fuwai Central China Cardiovascular Hospital of Zhengzhou University from March to October 2022 as DCM group, and 52 healthy volunteers were selected as the control group during the same period. The four-dimensional right ventricular ejection fraction (4D-RVEF), right ventricular stroke volume index (RVSVI), right ventricular end-diastolic volume index (RVEDVI), right ventricular end-systolic volume index (RVESVI), four-dimensional right ventricular basal diameter (4D-RVDd-base), four-dimensional right ventricular middle diameter (4D-RVDd-mid), four-dimensional right ventricular long axis diameter (4D-RVLd), four-dimensional tricuspid annular plane systolic excursion (4D-TAPSE) and four-dimensional right ventricular fractional area change (4D-RVFAC) were obtained by 4D Auto RVQ technique. The differences of the above parameters between DCM group and control group were compared.Pearson linear correlation analysis was used to evaluate the correlation between echocardiographic parameters and CMR-RVEF. The ROC curve was used to find the most sensitive parameters for evaluating right ventricular function, and the area under the ROC curve ( AUC ) was calculated and compared.Results:Compared with the control group, RVEDVI, RVESVI, 4D-RVDd-base and 4D-RVDd-mid in the DCM group were increased, and the absolute values of 4D-RVEF, 4D-TAPSE, 4D-RVFAC, right ventricular global longitudinal strain(RVGLS) and right ventricular free wall longitudinal strain(RVFWLS) were decreased (all P<0.05). Correlation analysis showed that 4D-RVEF was positively correlated with CMR-RVEF ( r=0.711, P<0.05). ROC curve analysis showed that 4D-RVEF was superior to other parameters in evaluating right ventricular function in DCM patients (AUC: 0.916). Conclusions:4D Auto RVQ technique can quantitatively evaluate right ventricular function in DCM patients. 4D-RVEF has a significant correlation with CMR-RVEF, and 4D-RVEF has the best efficacy in evaluating right ventricular function in DCM patients.

Objective:To predicate whether China can achieve the United Nations Sustainable Development Goals (SDGs) 3.4.1 to reduce the age-standardized mortality rate of four major non-communicable diseases (NCDs) in residents aged 30-70 years by 2030 based on the trend of the mortality from 1990 to 2019.Methods:We collected the mortality data on cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes by age, gender and year in China from the Global Disease Burden Study 2019 (GBD2019). The age-period-cohort (APC) Bayesian model was applied for modeling the age-standardized mortality rate of four major NCDs in China during 2020-2030 according to the trend of the mortality during 1990-2019, and comparing the predicted value in 2030 with the observed value in 2015 to evaluate the possibility of achieving SDGs 3.4.1.Results:The age-standardized mortality rate of the four major NCDs in China showed a downward trend during 1990-2019. It is predicted that the number of death of the four NCDs in Chinese residents aged 30-70 years would increase from 2.96 million in 2020 to 3.19 million in 2030, while the age-standardized mortality rate would decrease from 308.49/100 000 in 2020 to 277.80/100 000 in 2030. The age-standardized mortality rate in 2030 would only decrease by 15.94% (18.73% for males and 14.31% for females) compared with 330.46/100 000 in 2015, with a 25.09% decrease for cardiovascular diseases, 4.76% for cancers, 37.21% for chronic respiratory diseases, and unchanged for diabetes.Conclusion:Although the age-standardized mortality rate of four major NCDs declined from 1990 to 2019 in China, it is difficult to achieve the SDGs of a 1/3 mortality rate reduction by 2030 according to the current declining trend, suggesting more active and effective efforts for NCD prevention and control are needed.

Background Essential and non-essential elements have an important impact on the development of the central nervous system during fetal development. Due to their less developed brain, preterm infants are more sensitive to element exposure, and are high-risk groups of neurodevelopmental abnormalities. However, it is not clear whether the effects of element exposure in utero on postpartum neurodevelopment are different between full-term infants and preterm infants. Objective To evaluate the effects of element exposure levels during pregnancy on neurodevelopment of children aged 6-24 months (of corrected age), and compare the effects between preterm and full-term children. Methods A prospective study design was adopted and this study was conducted based on the Maoming Birth Cohort Study (MBCS) in Maoming City, Guangdong Province. Twenty elements in cord blood of 197 preterm infants and 297 full-term infants were measured, including 11 essential trace elements [vanadium (V), chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), selenium (Se), strontium (Sr), tin (Sn), and iron (Fe)], and 9 non-essential trace elements [aluminum (Al), arsenic (As), thallium (Tl), lead (Pb), uranium (U), cerium (Ce), antimony (Sb), cadmium (Cd), and yttrium (Y)]. The neurodevelopment of the children at 6, 12, and 24 months were evaluated by the Ages and Stages Questionnaires-the Third Edition (ASQ-3). A generalized estimating equation (GEE) model was adopted to evaluate the associations between elements and neurodevelopment in full-term and preterm children separately. Results The positive rates of 10 elements (Mn, Cu, Zn, Se, Sr, Fe, Sb, Tl, Pb, and As) in cord blood were greater than 80%. Among the preterm birth children, the results of GEE analysis showed that after adjusting for the covariates, for each increase of interquartile range (IQR) in ln-transformed concentration, As was associated with problems/delay in the communication and problem-solving sub-scales, with the adjusted odds ratios (OR) and 95% confidence intervals (CI) of 1.36 (1.03-1.80) and 1.55 (1.10-2.20), respectively; the adjusted OR (95%CI) of problems/delay in the fine motor and problem-solving sub-scales were 1.44 (1.00-2.07) and 1.76 (1.09-2.84) for Sb, respectively; the adjusted OR (95%CI) of problems/delay in the communication sub-scale was 1.37 (1.09-1.74) for Se. No statistically significant associations between umbilical cord blood element concentrations and neurodevelopment indicators were observed among full-term children. The results of stratified analysis by sex showed that the associations between umbilical cord blood element concentrations and neurodevelopment problems/delay were only significant among female preterm children. Conclusion Exposures to As, Se, and Sb during pregnancy may increase the risk of neurodevelopment problems/delay in preterm children aged 6-24 months, and female seem to be more vulnerable.

Objective:To compare the efficacy of stereotactic body radiotherapy(SBRT) and surgery in treating intrapulmonary recurrence of non-small cell lung cancer (NSCLC) after radical surgery.Methods:A retrospective analysis was conducted on NSCLC patients, who underwent radical surgery at the Cancer Hospital Affiliated to University of Chinese Academy of Sciences from November 2012 to December 2018 and then received SBRT or secondary surgery because of postoperative intrapulmonary recurrence. The survival rates of these patients were calculated using the Kaplan-Meier method. The comparison between the two groups was made using the Log-rank method, and the univariate and multivariate analysis was made using the Cox regression method.Results:Among 62 eligible patients, 33 received SBRT and 29 received secondary surgery, and they were divided into the SBRT group and the surgery group accordingly. For the SBRT and surgery groups, the median follow-up time was 45.8 months and 37.4 months, the 3-year locoregional control rate (LRCR) 79.8% and 90.2%, respectively ( P > 0.05), the progression-free-survival (PFS) 58.5% and 42.3%, respectively ( P >0.05), and the overall survival (OS) 78.0% and 85.5%, respectively ( P >0.05). The multivariate analysis suggested that treatment method, Charlson comorbidity index (CCI), and adjuvant drug therapy were independent prognostic factors for PFS ( P = 0.027, 0.013, 0.001). Conclusions:The efficacy of SBRT and surgery is comparable for patients with intrapulmonary recurrence of NSCLC after radical surgery.

Objective:To explore the normal ranges of perfusion parameters between cerebral hemisphere, cerebellar hemisphere and brain anatomical subregions (56 pairs) in different gender and age groups with multiple post labeling delay time (Multi-PLD) arterial spin labeling (ASL) imaging.Methods:From November 2020 to December 2020, 42 healthy adult volunteers (Male 25, Female 17) were recruited to perform 7 PLD ASL imaging, including 21 young adults (15 males and 6 females, aged 23—35 years) and 21 seniors (10 males and 11 females, aged 36—74 years). The data was processed offline by Cereflow software to obtain arterial arrival time (ATT) and corrected cerebral blood flow (CBF) and cerebral blood volume (CBV) perfusion parameters. SimpleITK standardization function was used to standardize the calculated perfusion image according to the anatomical automatic labeling (AAL) template. Therefore, CBF, ATT, CBV perfusion values of brain subregions were obtained. Paired samples t test, Wilcoxon rank sum test, independent samples t test and Mann-Whitney U test were used to compare the differences of perfusion parameters in the cerebral hemisphere, the cerebellar hemisphere, brain subregions depending on side, gender and age. Pearson correlation analysis was used to compare the correlations of perfusion parameters with age. Results:CBF in 62.5% (35/56) subregions and CBV in 44.6% (25/56) subregions were higher in right side than those in left side. ATT in most brain anatomical subregions (16/56) were higher in left side. The CBF [(35.30±8.31) vs. (34.34±7.53) ml·100g -1·min -1, P=0.021], CBV [(0.47±0.11) vs. (0.45±0.09) ml/100g, P<0.001], ATT [(1.30±0.10) vs. (1.24±0.11) s, P<0.001] in left cerebellar hemisphere were higher than that of right side. The CBF (28/56) of cerebral hemisphere, cerebellar hemisphere and brain subregions was higher in females than that in males, while ATT in 83.9% (47/56) subregions was lower than that in males (all P<0.05). CBV in female subjects was higher only in 5 brain regions (superior occipital gyrus, middle occipital gyrus, inferior occipital gyrus, superior parietal gyrus and cerebelum_7b) (all P<0.05). In young subjects, CBF in 44.6% (25/56) subregions and CBV in 33.9% (19/56) subregions were higher than those in the senior group (all P<0.05). The ATT in most subregions in young group were lower than those in senior group, but the difference was statistically significant only in rectus gyrus ( P=0.026) and paracentral lobule ( P=0.006). The CBF ( r=-0.430, P=0.005) and CBV ( r=-0.327, P=0.035) of cerebral hemisphere were negatively correlated with age. The CBF (24/25, r range:-0.497 —-0.343, all P<0.05) and CBV (16/19, r range:-0.474 —-0.322, all P<0.05) in most subregions were negatively correlated with age, while ATT was positively correlated (gyrus rectus: r=0.311, P=0.045; paracentral lobule: r=0.392, P=0.010). Conclusions:Multi-PLD ASL imaging could be applied for quantitative analysis of brain perfusion. The perfusion parameters of anatomical subregions are different depending on side, gender, and age.

Hegu needling is mainly used for the treatment of orthopedic and neurologic diseases, such as cervical spondylosis, third lumbar transverse process syndrome, myofasciitis, periarthritis of shoulder, and stroke sequela, which has a rapid and benefial effect in relieving pain and improving symptoms and signs. It is often combined with other treatment methods, such as point-point needling, electric needling, QI needling, SHU needling, bloodletting, stagnant needling, warm needling, ginger partitioned moxibustion, Qistimulated massage, Tuina, bonesetting and xercise therapy. Filiform needle or round sharp needle are mostly used in Hegu needling. At present, the acupoints of Hegu needling are mostly Ashi points or stimulation points, but the acupoints of the fourteen meridians are rarely selected. Hegu needling is rarely used in the treatment of gynecological and pediatric diseases. Hegu needling has certain effect on dementia, vertigo, panic attack, trigeminal neuralgia, facial paralysis, and cancer pain, but few clinical studies confirmedit.
