Objective:To observe the clinical efficacy of filiform needle combined with fire needles for cervical radiculopathy(CR)due to wind-cold obstructing the meridians. Methods:A total of 60 patients with CR due to wind-cold obstructing the meridians were randomized into an observation group and a control group,with 30 cases in each group.The control group was treated with filiform needle treatment,and the observation group was treated with additional fire needle point-pricking treatment.The visual analog scale(VAS)and 20-point scale of CR developed by Yasuhisa TANAKA(YT-20)were scored before treatment and after 1,2,3,and 4 weeks of treatments.The tenderness threshold was measured.The local skin temperature was measured by an infrared thermal imager.A safety evaluation was performed after treatment. Results:After treatment,the VAS score in the observation group at each time point was lower than that in the control group(P<0.05).The YT-20 score,tenderness threshold,and local skin temperature in the observation group were all higher than those in the control group(P<0.05).The VAS score in the observation group at each time point after treatment was lower than that before treatment(P<0.05),and the YT-20 score,tenderness threshold,and local skin temperature at each time point were higher than those before treatment(P<0.05).After 3 and 4 weeks of treatments,the VAS score in the control group was lower than that before treatment(P<0.05),and the YT-20 score,tenderness threshold,and local skin temperature were higher than those before treatment(P<0.05).The group factor effects of VAS and YT-20 scores,tenderness threshold,and local skin temperature between the two groups were statistically significant(P<0.05).There was no significant difference in the time effect and the interaction effect between time and group(P>0.05). Conclusion:Filiform needle combined with fire needle or applied alone both can relieve neck pain in patients with CR due to wind-cold obstructing the meridians,and improve the temperature of the neck.The combination of filiform needle and fire needle works more quickly and has better efficacy.

Ferroptosis,a programmed cell death induced by iron-dependent lipid peroxidation and excessive accumulation of reactive oxygen species,is a key pathological mechanism of neuronal death during the progression of Alzheimer's disease(AD),contributing to the formation of"Ferroptosis Hypothesis"for AD pathogenesis.In recent years,there has been extensive research on therapeutic strategies for AD based on the pathogenic mechanism of ferroptosis,focusing primarily on the dysregulation of brain iron metabolism and redox regulation in microenvironment.However,presence of blood-brain barrier and intricate pathological environment within brain impose limitations on intracranial drug transportation,distribution and therapeutic efficacy,thereby necessitating advancements in drug delivery technology.Based on description of ferroptosis process and its regulatory mechanisms,this review explores the association between iron overload and redox imbalance with neuronal loss and AD development,and additionally,summarizes the advancements in nano drug delivery systems targeting iron overload and redox imbalance for potential anti-AD treatments,so as to offer some novel perspectives for AD treatment and drug development.

Objective: As a gate-keeper enzyme link, pyruvate dehydrogenase E1 subunit alpha (PDHA1) functions as a key regulator during glycolysis and the mitochondrial citric acid cycle, which has been reported in several tumors. Nevertheless, the effects of PDHA1 on biological behaviors and metabolism remain unclear in cervical cancer (CC) cells. The study aims to explore the PDHA1 effects on glucose metabolism in CC cells and its possible mechanism. Methods: We first determined the expression levels of PDHA1 and activating protein 2 alpha (AP2α) as a PDHA1 potential transcription factor. The effects of PDHA1 in vivo were evaluated through a subcutaneous xenograft mouse model. Cell Counting Kit-8 assay, 5-ethynyl-2′-deoxyuridine (EdU) labeling assay, Transwell invasion assay, wound healing assay, Terminal deoxynucleotidyl transferase dUTP nick end labeling assay and flow cytometry were performed in CC cells. Oxygen consumption rate (OCR) levels were determined to reflect aerobic glycolysis level in gastric cancer cells. Reactive oxygen species (ROS) level was measured with 2′, 7′-dichlorofluorescein diacetate kit. The relationship between PDHA1 and AP2α was examined by conducting chromatin immunoprecipitation assay and electrophoretic mobility shift assay. Results: In CC tissues and cell lines, PDHA1 was downregulated, while AP2α was upregulated. Overexpression of PDHA1 remarkedly inhibited the proliferation, invasion and migration of CC cells, and tumor growth in vivo, as well as promoted OCR, apoptosis and ROS production. Moreover, AP2α directly bound to PDHA1 within suppressor of cytokine signaling 3 promoter region to negatively regulate PDHA1 expression level. What is more, PDHA1 knockdown could effectively reversed the AP2α silencing-mediated suppressive effects on cell proliferation, invasion, migration, and the promotive effects of AP2α knockdown on OCR, apoptosis and ROS production. Conclusions Our findings demonstrate that AP2α negatively regulated PDHA1 via binding to PDHA1 gene promoter to promote malignant CC cell behaviors, which may provide a potential approach for CC therapeutics.

Objective:To observe the curative effect of He Style fire acupuncture on functional dyspepsia of deficiency cold of spleen and stomach syndrome.Methods:Sixty patients who met the inclusion criteria from March 2017 to March 2019 in Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University were divided into 2 groups according to the random number table method, with 30 in each group. The control group was given mosapride tablets, one tablet (5 mg) each time half an hour before meals. On the basis of the control group, the treatment group was given fire acupuncture on Zusanli(ST36), Zhongwan(CV12), Pishu(BL20), Weishu(BL21), Guanyuan(CV4) and Qihai (CV6) twice a week. The course of treatment for both groups of patients was 4 weeks. A follow-up was visited at 1 month after the treatment. The total Symptom Scores and Health-Related Quality of Life Scale (SF-36) scores were performed before and after treatment, and the total scores of syndromes of patients with Deficiency cold of spleen and stomach before and after treatment were used for clinical efficacy evaluation, and adverse events during treatment were recorded.Results:The total efficiency of the treatment group was 93.3% (28/30), and 76.7% (23/30) in the control group, and the 2 groups were statistically significant ( χ2=4.78, P<0.05). After treatment, the upper abdominal pain, upper abdominal burning, postprandial fullness and discomfort, early satiety, and total scores in the treatment group were significantly lower than those in the control group ( t values were 4.27, 5.16, 3.93, 4.69, 4.28, respectively, all Ps<0.05); during follow-up, the upper abdominal pain, upper abdominal burning, postprandial fullness and discomfort and the total scores in the treatment group were significantly lower than those in the control group ( t values were 3.63, 3.22, 4.03, 3.04, respectively, all Ps<0.05). In terms of SF-36, after treatment, the treatment group showed significantly higher scores in the control group of physical function, physiology, mental health, and health changes compared with the control group ( t values were 2.97, 4.05, 4.22, 3.05, respectively, all Ps<0.05). During follow-up, the treatment group with physiological function, physical function, physical pain, overall health, life vitality, mental health, health changes scores were significantly higher than those in the control group ( t values were 3.27, 4.23 3.85, 3.15, 3.25, 6.15, 3.85, respectively, all Ps<0.05). Conclusion:He Style fire acupuncture combined with western medicine treatment can improve the symptoms of upper abdominal pain and upper abdominal burning, and the quality of lifein the patients with functional dyspepsia.

Objective:To study peripheral nerve morphology in patients with transthyretin familial amyloid polyneuropathy (TTR-FAP) using high-frequency ultrasonography (HFUS), and to evaluate the value of HFUS in diagnosis of TTR-FAP.Methods:Thirty-eight patients with TTR-FAP diagnosed by gene detection and 23 normal controls from June 2015 to June 2021 in Peking University First Hospital were enrolled in this study. Consecutive ultrasonography scanning was performed in 6 pairs of nerves of bilateral limbs with 30 sites. The cross sectional area (CSA), CSA variability and inter-nerve CSA variability data of the two groups were retrospectively calculated and compared.Results:Compared with the normal controls, TTR-FAP patients showed larger CSA values at most nerve sites of both upper and lower limbs, and there were statistically significant differences at M1(median nerve) [8.55 (6.90, 9.40) mm 2vs 10.05 (9.10, 14.10) mm 2, Z=5.58, P<0.001], M3 (median nerve) [(6.98±1.66) mm 2vs (9.29±2.30) mm 2, t=6.28, P<0.001], M5 (median nerve) [(8.91±1.81) mm 2vs (14.33±4.20) mm 2, t=9.84, P<0.001], U5 (ulnar nerve) [(6.20±1.93) mm 2vs (9.34±2.85) mm 2, t=7.31, P<0.001], Sci1 (sciatic nerve) [(53.50±17.24) mm 2vs (79.74±20.75) mm 2, t=7.57, P<0.001], Sci2 (sciatic nerve) [(53.66±14.21) mm 2vs (73.98±19.21) mm 2, t=6.82, P<0.001] and Tib (tibial nerve) [(31.05±8.43) mm 2vs (46.29±13.14) mm 2, t=7.84, P<0.001] sites. There was no statistically significant difference in CSA at each site among the different subtypes and disease severity of TTR-FAP patients ( P>0.05). There was no statistically significant difference in CSA-variability of the median and ulnar nerves between the patients with TTR-FAP and the normal controls ( P>0.05). The side-to-side difference ratio of intra-nerve CSA variability of the ulnar nerve in the patients with TTR-FAP was smaller than that of the normal controls (1.15±0.10 vs 1.46±0.43, t=3.43, P=0.002), whereas no statistically significant difference of that in the median nerve was found between the two groups ( P>0.05). Conclusions:The most pronounced peripheral nerve thickening in the proximal limb segments with no signs of asymmetric distribution or lateralization is confirmed by HFUS in TTR-FAP patients and should be regarded as a marker of TTR-FAP. HFUS has clinical value in diagnosis of peripheral neuropathy in TTR-FAP patients.

Objective:To investigate the normal reference values of spinal bone mineral density measured by quantitative computed tomography (QCT) and the differences of bone mineral density (BMD) in different regions of in Chinese adult males.Methods:Men who underwent low-dose CT lung scan for cancer screening in regions of Northeast, North, East, South, Central and Southwest of China from January 2018 to December 2019 were selected. And the lumbar vertebrae BMD values in the male subjects were measured by the QCT system (Mindways Software, Inc.). The mean BMD values and their decline rates were calculated at an age interval of 10 years, and the prevalence of osteoporosis was calculated according to the American College of Radiology spine QCT osteoporosis diagnostic criteria.Results:A total of 50 682 males with a mean age of (50.22±12.79) years (ranged 20 to 98 years) were included in this study. The peak BMD of (173.11±28.56) mg/cm 3 in the healthy Chinese adult male population appeared in the age group of 20 to 29 years and then declined with age. Before the age of 70 years, the BMD was relatively higher in males in South China, and it was lower in Central China and Southwest China, and it was intermediate in Northeast, North and East of China, with statistically significant differences. There was no significant differences in BMD in the males in the two age groups of 70 to 79 years and 80 and older among the regions in China. The overall decline rate of spinal BMD in Chinese males under QCT was about 46.92% over the lifetime, and it declined obviouslyin the 40-49 age group. The overall prevalence of osteoporosis in Chinese male population aged 50 years and above was approximately 11.42%, with the highest prevalence in Southwest China and Central China (14.72% and 13.87%, respectively) and the lowest in North China and South China (8.53% and 7.71%, respectively). Conclusions:A reference of lumbar spine BMD values for healthy males in China based on QCT is established. BMD values were highest in South China and Lowest in Central China.

ObjectiveTo evaluate the effect of standardized blood pressure measurement in consulting room （SBPM） model on blood pressure screening of non-hypertensive patients in community. MethodsFour communities were randomly selected from Fengxian District of Shanghai， and non-hypertensive patients in the communities were included for screening. Based on the communities， participants were further classified into the intervention group and control group. A one-year intervention study was conducted from January 1， 2021 to December 31， 2021. The intervention group received the intervention measures of standardized measurement， and the control group remained the routine measurement. The distribution of blood pressure values and last digit of the values between the intervention group and control group were tested using Chi-square test and normality test. Then changes in abnormal blood pressure rate before and after the intervention were determined by double difference method. Statistical analysis was performed using SPSS 20.0. ResultsA total of 15 368 participants were included in the intervention group， and 19 811 participants in the control group. After the intervention， range of the last digit of blood pressure values in the intervention group was 9.55%‒10.41%， of which that of systolic and diastolic blood pressure were equally distributed （P=0.932 and 0.871， respectively）. The range of the last digit in the control group was 1.31%‒42.58%， of which that of systolic and diastolic blood pressure showed unequal distribution （P<0.001）. Through one-year standardized measurement intervention， the abnormal rate of blood pressure in the intervention group was 26.29%， which was 7.61 times as high as that in the control group （OR=7.55， 95%CI： 6.75‒8.57， P<0.001）. ConclusionStandardized blood pressure measurement in consulting room is suitable for the screening of blood pressure measurement in community， which has higher data quality than that of routine measurement.

Objective:To investigate the clinical characteristics, efficacy and prognostic influencing factors of IgD multiple myeloma (MM) in the new immunotherapy era.Methods:The clinical data of 29 patients diagnosed with IgD MM in the Affiliated Hospital of Xuzhou Medical University from March 2014 to February 2021 were retrospectively collected. The clinical characteristics, treatment regimens and efficacy, especially the efficacy of new drugs and immunotherapy for the disease were analyzed. Kaplan-Meier method was used to analyze the overall survival (OS) and progression-free survival (PFS). Multivariate Cox proportional risk model was used for analysis of prognostic influencing factors.Results:The median age of patients was 58 years. There were 20 cases (69.0%) below 65 years, 12 cases (41.4%) of complicated with stomach function damage, 6 cases (20.7%) of extramedullary invasion. All patients were treated with combined therapy containing proteasome inhibitor bortezomib in the first-line therapy, and the overall response rate was 82.8% (24/29). Among 21 relapsed/refractory patients, 12 patients were treated with the second-line or above treatment regimen chimeric antigen receptor T cell (CAR-T) immunotherapy, including 9 cases achieving very good partial remission (VGPR) or above; 5 patients were treated with the new drug daratozumab, including 1 case achieving complete remission (CR). The median OS time of 29 patients was 48 months (95% CI 17-79 months), the median PFS time after the first-line treatment was 9 months (95% CI 3-15 months), and the median PFS time after the second-line treatment was 11 months (95% CI 1-21 months). Multivariate Cox regression results showed that CAR-T therapy is an independent influencing factor of the prognosis of relapsed/ refractory IgD MM patients ( HR = 0.094, 95% CI 0.019-0.473, P = 0.004). Conclusions:IgD MM patients are characterized with lower onset age, more renal function damage and a high incidence of extramedullary invasion. The first-line therapy containing proteasome inhibitor has a better short-term efficacy, and CAR-T therapy can improve the remission rate and survival rate of relapsed/refractory IgD MM to a certain extent.

Objective:To explore the influence of prognostic nutritional index (PNI) and controlling nutritional status (CONUT) on the prognosis of patients with multiple myeloma.Methods:Data of 157 patients with multiple myeloma (MM) at the affiliated hospital of Xuzhou medical university from January 2014 to December 2018 were retrospectively evaluated. The operating characteristic (ROC) curve analysis was adopted as the optimal cut-off point. PNI and CONUT were grouped based on the cut-off points of 44.45 and 3.5, respectively, and the differences between age, gender, serum calcium, β 2-microglobulin, serum creatinine, lactate dehydrogenase, and hemoglobin were analyzed. The prognostic factors were analyzed via univariate and Cox multivariate regression analyses. Results:The level of PNI and CONUT is the influencing factor of OS time. The univariate analysis revealed that age, LDH, plasma cell ratio, β 2-microglobulin, ISS stage, PNI, and CONUT were the risk factors for the prognosis of patients with MM. The multivariate analysis revealed that age ( HR=1.636, 95% CI 1.014-2.640) , plasma cell ratio ( HR=1.953, 95% CI 1.232-3.096) , and PNI ( HR=0.513, 95% CI 0.287-0.917) were the independent prognostic risk factors of patients with MM. Conclusion:Low PNI in patients with MM indicates a poor prognosis, which is an independent prognosis risk factor.

Objective:To analyze the effect of family involvement in nursing on the recovery effect of children with thrombocytopenic purpura (ITP).Methods:A total of 55 children with ITP in our hospital who were not given family involvement in nursing between January and December 2017 were included in the control group and 63 children with ITP who were given family involvement in nursing between January and December 2018 were included in the observation group. The hospital stay, platelet count (PLT) recovery time, compliance (emotional control, diet, medication), mastery of health knowledge of family members and short-term prognosis were compared between the 2 groups.Results:The recovery time of PLT count (30-50)×10 9/L and (51-100)×10 9/L in the observation group was (1.97±0.56) d, (3.41±0.45) d, which was shorter than those of the control group [(2.79±0.59) d, (4.02±1.22) d] ( t value was 7.739, 3.693, P < 0.05). The scores of emotional control, dietary compliance and medication compliance and total score of compliance of the observation group on the day of discharge were 7.25 ± 1.17 , 8.18 ± 1.19 , 7.47 ± 1.35 , 21.26 ± 4.92, which were higher than those of the control group (5.11 ± 1.34, 5.79 ± 1.25, 4.86 ± 1.75, 15.76 ± 4.34) ( t value was -10.630- -6.397, all P < 0.05). On the day of discharge, the scores of condition monitoring, prevention of complications, dietary guidance, medication guidance, mastery of health knowledge and total score of family members of the observation group were higher than those of the control group ( t value was -7.705-5.949, all P< 0.05). Conclusions:Family involvement in nursing can improve the mastery of health knowledge about ITP of family members and children′s compliance, which is conductive to the recovery of PLT count in children with ITP. It may improve the short-term prognosis.
