ABSTRACT

Pyroptosis is a novel process of programmed inflammatory necrosis, which is closely related to microbial infections and autoimmune diseases. In recent years it has been proved that Gasdermin D is an executive protein of pyroptosis. Cleaved Gasdermin D leads to the formation of pores in cell membrane to induce pyroptosis, and the release of inflammatory factors such as IL-1β and IL-18 aggravates the occurrence of inflammatory responses. With the deepening of Gasdermin D research, it is gradually clear its protein structure and activation sites, which has other activation pathways apart from inducing inflammasome activation. Activation of Gasdermin D does not necessarily mean cell death, even if it could induce the formation of pores in cell membrane and regulation of inflammatory cytokine secretion. These findings offer insight into Gasdermin D function and change our understanding of pyroptosis and programmed necrosis. The recent progress of Gasdermin D is highlighted in this review.

ABSTRACT

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

ABSTRACT

OBJECTIVE@#To evaluate the clinical outcomes of reverse total shoulder arthroplasty as a revision procedure for the failed fixation of proximal humeral fractures in the elderly patients.@*METHODS@#A retrospective analysis was performed on 8 patients with failed internal fixation of proximal humeral fractures from May 2014 to March 2020, including 3 males and 5 females, aged from 65 to 75 years old. All 8 patients underwent reverse total shoulder arthroplasty, and the mean time between initial fixation and reverse total shoulder arthroplasty ranged from 8 to 16 months. Range of motion(ROM), University of California at Los Angeles(UCLA) shoulder score, visual analogue scale (VAS), self-rating anxiety scale(SAS), and Constant-Murley score of shoulder function were assessed pre-operatively and at the last follow-up. Complications relating to the surgery were recorded.@*RESULTS@#All 8 patients successfully followed up. The mean follow-up after reverse total shoulder arhroplasty ranged from 16 to 28 months. The range of motion (forward flexion, external rotation, abduction and internal rotation) of the affected shoulder was significantly improved after surgery, and the post-operative VAS, SAS and UCLA scores were also significantly improved. For the Constant-Murley score of shoulder joint function, the total scores and the subscores of pain, daily activities, range of motion and strength test at the last follow-up were all significantly improved. Scapular glenoid notch was observed in patient, which was evaluated as grade 1 on imaging. All the other patients did not develop specific or non-specific complications.@*CONCLUSION@#Reverse total shoulder arhroplasty is an appropriate treatment as a revision surgery for failed fixation of proximal humeral fractures. It has shown satisfactory clinical outcomes, accelerating the rehabilitation of shoulder function and improving the quality of life.

ABSTRACT

OBJECTIVE@#To investigate the effect of baicalin on the growth of extranodal NK/T cell lymphoma (ENKTCL) cells and its related mechanism.@*METHODS@#Normal NK cells and human ENKTCL cells lines SNK-6 and YTS were cultured, then SNK-6 and YTS cells were treated with 5, 10, 20 μmol/L baicalin and set control. Cell proliferation and apoptosis was detected by Edu method and FCM method, respectively, and expressions of BCL-2, Bax, FOXO3 and CCL22 proteins were detected by Western blot. Interference plasmids were designed and synthesized. FOXO3 siRNA interference plasmids and CCL22 pcDNA overexpression plasmids were transfected with PEI transfection reagent. Furthermore, animal models were established for validation.@*RESULTS@#In control group and 5, 10, 20 μmol/L baicalin group, the proliferation rate of SNK-6 cells was (56.17±2.96)%, (51.92±4.63)%, (36.42±1.58)%, and (14.60±2.81)%, respectively, while that of YTS cells was (58.85±2.98)%, (51.38±1.32)%, (34.75±1.09)%, and (15.45±1.10)%, respectively. In control group and 5, 10, 20 μmol/L baicalin group, the apoptosis rate of SNK-6 cells was (5.93±0.74)%, (11.78±0.34)%, (28.46±0.44)%, and (32.40±0.37)%, respectively, while that of YTS cells was (7.93±0.69)%, (16.29±1.35)%, (33.91±1.56)%, and (36.27±1.06)%, respectively. Compared with control group, the expression of BCL-2 protein both in SNK-6 and YTS cells decreased significantly (P<0.001), and the expression of Bax protein increased in SNK-6 cells only when the concentration of baicalin was 20 μmol/L (P<0.001), while that in YTS cells increased in all three concentrations(5, 10, 20 μmol/L) of baicalin (P<0.001). The expression of FOXO3 protein decreased while CCL22 protein increased in ENKTCL cell lines compared with human NK cells (P<0.001), but the expression of FOXO3 protein increased (P<0.01) and CCL22 protein decreased after baicalin treatment (P<0.001). Animal experiments showed that baicalin treatment could inhibit tumor growth. The expression of CCL22 protein in ENKTCL tissue of nude mice treated with baicalin decreased compared with control group (P<0.01), while the FOXO3 protein increased (P<0.05). In addition, FOXO3 silencing resulted in the decrease of FOXO3 protein expression and increase of CCL22 protein expression (P<0.01, P<0.001).@*CONCLUSION@#Baicalin can inhibit proliferation and promote apoptosis of ENKTCL cell lines SNK-6 and YTS, up-regulate the expression of Bax protein, down-regulate the expression of BCL-2 protein, and down-regulate the expression of CCL22 protein mediated by FOXO3. Animal experiment shown that the baicalin can inhibit tumor growth. Baicalin can inhibit the growth and induce apoptosis of ENKTCL cells through FOXO3/CCL22 signaling pathway.

ABSTRACT

OBJECTIVE@#To investigate the effect of Baicalin on the proliferation and pyroptosis of diffuse large B-cell lymphoma cell line DB and its mechanism.@*METHODS@#DB cells were treated with baicalin at different concentrations (0, 5, 10, 20, 40 μmol/L). Cell proliferation was detected by CCK-8 assay and half maximal inhibitory concentration (IC50) was calculated. The morphology of pyroptosis was observed under an inverted microscope, the integrity of the cell membrane was verified by LDH content release assay, and the expressions of pyroptosis-related mRNA and protein (NLRP3, GSDMD, GSDME, N-GSDMD, N-GSDME) were detected by real-time fluorescence quantitative PCR and Western blot. In order to further clarify the relationship between baicalin-induced pyroptosis and ROS production in DB cells, DB cells were divided into control group, baicalin group, NAC group and NAC combined with baicalin group. DB cells in the NAC group were pretreated with ROS inhibitor N-acetylcysteine (NAC) 2 mmol/L for 2 h. Baicalin was added to the combined treatment group after pretreatment, and the content of reactive oxygen species (ROS) in the cells was detected by DCFH-DA method after 48 hours of culture.@*RESULTS@#Baicalin inhibited the proliferation of DB cells in a dose-dependent manner (r=-0.99), and the IC50 was 20.56 μmol/L at 48 h. The morphological changes of pyroptosis in DB cells were observed under inverted microscope. Compared with the control group, the release of LDH in the baicalin group was significantly increased (P<0.01), indicating the loss of cell membrane integrity. Baicalin dose-dependently increased the expression levels of NLRP3, N-GSDMD, and N-GSDME mRNA and protein in the pyroptosis pathway (P<0.05). Compared with the control group, the level of ROS in the baicalin group was significantly increased (P<0.05), and the content of ROS in the NAC group was significantly decreased (P<0.05). Compared with the NAC group, the content of ROS in the NAC + baicalin group was increased. Baicalin significantly attenuated the inhibitory effect of NAC on ROS production (P<0.05). Similarly, Western blot results showed that compared with the control group, the expression levels of pyroptosis-related proteins was increased in the baicalin group (P<0.05). NAC inhibited the expression of NLRP3 and reduced the cleavage of N-GSDMD and N-GSDME (P<0.05). Compared with the NAC group, the NAC + baicalin group had significantly increased expression of pyroptosis-related proteins. These results indicate that baicalin can effectively induce pyroptosis in DB cells and reverse the inhibitory effect of NAC on ROS production.@*CONCLUSION@#Baicalin can inhibit the proliferation of DLBCL cell line DB, and its mechanism may be through regulating ROS production to affect the pyroptosis pathway.

ABSTRACT

Objective To investigate HPV vaccine hesitancy and influencing factors among parents of primary and secondary schools in Guangyuan, and to provide scientific countermeasures for reducing the hesitancy rate of HPV vaccine in parents. Methods Using stratified multi-stage cluster random sampling, 1,018 parents of girls in primary and secondary schools in Guangyuan were selected for a questionnaire survey from March to July 2021. The data were analyzed by Chi-square test and multivariate logistic regression model. Results The hesitancy rate of HPV vaccine in parents was 42.95%. Multivariate logistic regression analysis showed that families with low economic income, parents who believed that HPV vaccination would have long-term side effects, and be unsafe and expensive, and parents who concerned with the effect of HPV vaccine on the prevention of cervical cancer and insufficient supply of first doses of vaccine, had positive effects on HPV vaccine hesitancy (OR = 2.02, 1.44, 3.13, 1.53, 3.76, and 2.43, respectively, P < 0.05). Conclusion HPV vaccine hesitancy rate is high among parents of primary and secondary schools in Guangyuan. It is necessary to fully promote school education and increase the publicity of HPV vaccine to improve parents' awareness of HPV vaccine. Government departments need to make an overall plan to reduce vaccine costs and ensure sufficient vaccine quantity, so as to reduce parents' hesitation to vaccinate their children with HPV vaccine.

ABSTRACT

BACKGROUND@#Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed.@*OBJECTIVE@#To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs.@*SEARCH STRATEGY@#Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review."@*INCLUSION CRITERIA@#SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs.@*RESULTS@#A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm.@*CONCLUSION@#The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common malignancies and a leading cause of cancer-related death worldwide. Surgery remains the primary and most successful therapy option for the treatment of early- and mid-stage HCCs, but the high heterogeneity of HCC renders prognostic prediction challenging. The construction of relevant prognostic models helps to stratify the prognosis of surgically treated patients and guide personalized clinical decision-making, thereby improving patient survival rates. Currently, the prognostic assessment of HCC is based on several commonly used staging systems, such as Tumor-Node-Metastasis (TNM), Cancer of the Liver Italian Program (CLIP), and Barcelona Clinic Liver Cancer (BCLC). Given the insufficiency of these staging systems and the aim to improve the accuracy of prognostic prediction, researchers have incorporated further prognostic factors, such as microvascular infiltration, and proposed some new prognostic models for HCC. To provide insights into the prospects of clinical oncology research, this review describes the commonly used HCC staging systems and new models proposed in recent years.

ABSTRACT

As a widespread pollutant in the environment, research on microplastics have attracted much attention. This review systematically analyzed the interaction between microplastics and soil microorganisms based on existing literatures. Microplastics can change the structure and diversity of soil microbial communities directly or indirectly. The magnitude of these effects depends on the type, dose and shape of microplastics. Meanwhile, soil microorganisms can adapt to the changes caused by microplastics through forming surface biofilm and selecting population. This review also summarized the biodegradation mechanism of microplastics, and explored the factors affecting this process. Microorganisms will firstly colonize the surface of microplastics, and then secrete a variety of extracellular enzymes to function at specific sites, converting polymers into lower polymers or monomers. Finally, the depolymerized small molecules enter the cell for further catabolism. The factors affecting this degradation process are not only the physical and chemical properties of the microplastics, such as molecular weight, density and crystallinity, but also some biological and abiotic factors that affect the growth and metabolism of related microorganisms and the enzymatic activities. Future studies should focus on the connection with the actual environment, and develop new technologies of microplastics biodegradation to solve the problem of microplastic pollution.

ABSTRACT

Evodiamine(EVO)is an indoloquinazoline alkaloid isolated from the fruits of Euodia rutaecarpa,which has long been used in traditional Chinese medicine to treat various diseases.Modern medical research shows that evodiamine has various pharmacological activities and extremely high medicinal value such as anti-inflammation,anti-tumor,losing weight,treating Alzheimer's,and antibacterium.Evodiamine can interact with a variety of proteins.For example,the interaction between evodiamine and TRPV1 induces its activation to exert anti-inflammatory and losing weight; the interaction with DNA topoisomerase I inhibits its function and thus inhibit bacterial proliferation; the interaction with tubulin promotes NLRP3 inflammasome activation,and exerts anti-tumor and anti-inflammatory functions.In recent years,with the in-depth study of evodiamine,pharmacological research and mechanism of evodiamine has significant improvement.Recent progress of pharmacological effect of evodiamine is highlighted in this review.

ABSTRACT

The risk of plague epidemics and relapse of various types of plague foci persists in Inner Mongolia Autonomous Region. For Marmota sibirica plague foci, the animal plague has not been found but antibody has been detected positive. Nowadays, Marmota sibirica has been increasing in population and distribution in China. In bordering countries Mongolia and Russia, the animal plague has been continuously prevalent. For Spermophilus dauricus plague foci, the animal plague has been taken place now and then. Compared to the above foci, the animal plague is most prevalent in Meriones unguiculatus plague foci and frequently spread to humans. Due to higher strain virulence and historical disaster in Marmota sibirica plague foci and Spermophilus dauricus plague foci, plague prevention and control should be strengthened on these foci. In addition to routine surveillance, epidemic dynamics need to be further monitored in these two foci, in order to prevent their relapse and spread to humans.

ABSTRACT

Brain-lung-thyroid syndrome is a rare autosomal dominant disorder. More than 100 cases have been reported worldwide, but few cases have been reported in China. In December 2018, a boy with brain-lung-thyroid syndrome, aged 3 years and 10 months, was admitted to Xiangya Hospital of Central South University due to repeated cough for more than 3 years. In infancy of the boy, psychomotor retardation, repeated cough, and hypothyroidism were found. Gene detection showed that there was c.927delc heterozygous variation in NKX2-1 gene (NM-001079668: exon3: c.927delC). The variation of this gene locus has not been reported in relevant literature so far, which indicates a new mutation. According to the above clinical manifestations and examination results, the boy was diagnosed as brain-lung-thyroid syndrome, which mainly characterized by nervous system disorders, accompanied by respiratory manifestations and hypothyroidism. The boy was treated with oral dopasehydrazine to relieve tremor and levothyroxine sodium tablets to relieve hypothyroidism. Anti-infection, atomization, rehabilitation training and other symptomatic supporting treatment were also administered. The boy's language and movement have improved, the thyroid hormone level is normal, and there are still repeated respiratory tract infections.

ABSTRACT

OBJECTIVE@#To evaluate the effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on motor function and gait of the lower limbs in post-stroke hemiplegia patients.@*METHODS@#A total of 231 patients with post-stroke hemiplegia was randomly divided into IDSA (78 cases), SCT (78 cases), and TSA (75 cases) groups by a random number table. Scalp acupuncture (SA) and lower-limb robot training (LLRT) were both performed in the IDSA and SCT groups. The patients in the TSA group underwent SA and did not receive LLRT. The treatment was administered once daily and 6 times weekly for 8 continuous weeks, each session lasted for 30 min. The primary outcome measures included Fugl-Meyer assessment of the lower extremity (FMA-LE), berg balance scale (BBS), modified barthel index (MBI), and 6-min walking test (6MWT). The secondary outcome measures included stride frequency (SF), stride length (SL), stride width (SW), affected side foot angle (ASFA), passive range of motion (PROM) of the affected hip (PROM-H), knee (PROM-K) and ankle (PROM-A) joints. The patients were evaluated before treatment, at 1- and 2-month treatment, and 1-, and 2-month follow-up visits, respectively. Adverse events during 2-month treatment were observed.@*RESULTS@#Nineteen patients withdrew from the trial, with 8 in the IDSA and 5 in the SCT groups, 6 in the TSA group. The FMA-LE, BBS, 6MWT and MBI scores in the IDSA group were significantly increased after 8-week treatment and 2 follow-up visits compared with the SCT and TSA groups (P<0.05 or P<0.01). Compared with pre-treatment, the grade distribution of BBS and MBI scores in the 3 groups were significantly improved at 1, 2-month treatment and 2 follow-up visits (P<0.05 or P<0.01). The SF, PROM-H, PROM-K and PROM-A in the IDSA group was significantly increased compared with the SCT and TSA groups after 8-week of treatment (P<0.05 or P<0.01). Compared with the SCT group, ASFA of the IDSA group was significantly reduced after 8-week of treatment (P<0.05). SF, SL, PROM-K and PROM-A were significantly increased at the 2nd follow-up visit whereas the ASFA was significantly reduced in the IDSA group compared with the SCT groups at 1st follow-up visit (P<0.05 or P<0.01). The SF was significantly increased in the SCT group compared with the TSA group after 8-week treatment (P<0.05). Compared with the TSA group, PROM-K, PROM-A were significantly increased at the 2nd follow-up visit (P<0.05).@*CONCLUSIONS@#The effects of IDSA on lower-limb motor function and walking ability of post-stroke patients were superior to SCT and TSA. The SCT was comparable to TSA treatment, and appeared to be superior in improving the motion range of the lower extremities. (Registration No. ChiCTR1900027206).

ABSTRACT

OBJECTIVE@#To explore the characteristics and rules of acupoint sensitization phenomena based on knee osteoarthritis (KOA), one of the clinical dominant diseases of acupuncture-moxibustion.@*METHODS@#In combination with literature and expert experiences, the acupoints with the highest use frequency in treatment of KOA were screened, e.g. Heding (EX-LE 2), Liangqiu (ST 34), Mingmen (GV 4), Neixiyan (EX-LE 4), Ququan (LR 8) and Dubi (ST 35). In 814 patients with KOA and 217 healthy subjects, the acupoint temperature, mechanic pain threshold and pressure pain threshold were detected separately. Using machine learning method, the sensitization was judged at each acupoint.@*RESULTS@#Compared with healthy subjects, the acupoint temperature was increased and the mechanic pain threshold and pressure pain threshold were reduced in KOA patients (P<0.05). Besides, the cut-off value was presented to distinguish whether the acupoint was sensitized or not. The results of machine learning showed that the highest prediction accuracy of acupoint sensitization was 86.7% (Shenshu [BL 23]) and the lowest one was 73.9% (Heding [EX LE 2]). The prediction accuracy at the third clinical stage trial was higher, the highest was 93.3% (Ququan [LR 8]) in KOA patients.@*CONCLUSION@#It is confirmed that the acupoint sensitization reflects the characteristics of disease and is correlative with the conditions of illness, which may provide the reference for the auxiliary diagnosis and condition assessment of KOA.

ABSTRACT

OBJECTIVE@#To compare the clinical effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on cognitive function, depression and anxiety in patients with post-stroke cognitive impairment.@*METHODS@#A total of 660 patients with post-stroke cognitive impairment who were admitted to 3 hospitals in Shenzhen City between May 2017 and May 2020 were recruited and randomly assigned to the IDSA (218 cases), SCT (222 cases) and TSA groups (220 cases) according to a random number table. All the patients received conventional drug therapy for cerebral stroke and exercise rehabilitation training. Scalp acupuncture and computer-based cognitive training (CBCT) were performed simultaneously in the IDSA group, but separately in the morning and in the afternoon in the SCT group. The patients in the TSA group underwent scalp acupuncture only. The course of treatment was 8 weeks. Before treatment (M0), 1 (M1) and 2 months (M2) after treatment, as well as follow-up at 1 (M3) and 2 months (M4), the cognitive function of patients was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) Scales; depression, anxiety, sleep quality, and self-care ability of patients were assessed using Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), Pittsburgh Sleep Quality Index (PSQI), and Modified Barthel Index (MBI), respectively. During this trial, all adverse events (AEs) were accurately recorded.@*RESULTS@#There were no significant differences in the MMSE, MoCA, HAMD, HAMA, PSQI, and MBI scores among the 3 groups at M0 (all P>0.05). In the IDSA group, the MMSE, MoCA and MBI scores from M2 to M4 were significantly higher than those in the SCT and TSA groups, while the HAMD, HAMA and PSQI scores were significantly reduced (all P<0.01). The changes of all above scores (M2-M0, M4-M0) were significantly superior to those in the SCT and TSA groups (all P<0.01, except M4-M0 of HAMD). At M2, the severity of MMSE, HAMD, HAMA, PSQI and MBI in the IDSA group was significantly lower than that in the SCT and TSA groups (all P<0.01). There was no serious AE during this trial.@*CONCLUSIONS@#IDSA can not only significantly improve cognitive function, but also reduce depression, anxiety, which finally improves the patient's self-care ability. The effect of IDSA was significantly better than SCT and TSA. (Trial registration No. ChiCTR1900027206).

ABSTRACT

OBJECTIVE@#To observe the influence of acupuncture on microcirculation perfusion of the pericardium meridian and heart in acute myocardial ischemia (AMI) rats and evaluate whether acupuncture can simultaneously affect the meridians and corresponding viscera. Additionally, acupoints at different meridians were compared and whether they exert the same effects was discussed.@*METHODS@#Totally 32 Sprague-Dawley rats were subjected to left anterior descending (LAD) ligation to develop an AMI model. Rats were divided into 4 groups, including AMI, acupuncture Neiguan (PC 6), Lieque (LU 7) and Qiansanli (LI 10) groups (n=8). Eight rats received only thoracotomy (sham-operated group). The rats in the acupuncture groups received manual acupuncture at PC 6, LU 7 and LI 10 acupoints for 15 min, respectively. The microcirculation perfusion of pericardium meridian and heart was monitored by laser speckle perfusion imager (LSPI) before, during and after acupuncture manipulation for 15 min. Subsequently, the perfusion unit (PU) was calculated and analyzed by PSI System.@*RESULTS@#After LAD, compared to pre-acupuncture stage, the heart microcirculation perfusion (HMP) in the AMI group decreased continuously at during-acupuncture (P>0.05) and post-acupuncture stages (P0.05). Compared to pre-acupuncture stage, the PMP and HMP in PC 6 group significantly increased during acupuncture manipulation (both P0.05); however, they were significantly reduced after acupuncture manipulation (both P<0.05). Additionally, HMP of LI 10 group was decreased significantly during acupuncture, especially compared to pre-acupuncture stage (P<0.05).@*CONCLUSIONS@#Acupuncture at PC 6 obviously increased the PMP and HMP in AMI rats, and the effects were superior to at LU 7 and LI 10 acupoints. It was further confirmed that acupuncture promoted qi and blood circulation, indicating that acupoint specificity exists and features a meridian-propagated effect.

ABSTRACT

Objective To investigate the real correlation between embryo density and developmental outcome of cleavage embryos on day 3 by adjusting covariates. Methods Data of 1196 embryos from 206 couples undergoing in vitro fertilization and embryo transfer(IVF-ET) treatment were retrospectively analyzed. Embryos were hypoxia-cultivated in a fixed 30 μl microdrop in culture dishes. Embryo quality on day 3 was evaluated and proportion of good quality cleavage embryos on day 3 was used as the endpoint. Maternal age, paternal age, antral follicles, level of anti-mullerian hormone (AMH), type of infertility, controlled ovarian stimulation(COS) protocol, length of stimulation, number of retrieved oocytes, and type of insemination were chosen as covariates. Results A total of 1196 embryos were included and analyzed. Three embryo densities were routinely used: 30 μl/ embryo [1 embryo/ (30 μl·drop)], 15 μl/ embryo [2 embryos / (30 μl·drop)] and 10 μl/ embryo [3 embryos/ (30 μl·drop)]. The number of embryos assigned into these three groups were 434, 646 and 116 embryos separately. The average proportion of good quality embryos on day 3 in 10 μl/ embryo group were lower than that in both 15 and 30 μl/ embryo group (29. 31% vs 40. 25%,P 0. 05). In the regression analysis, without adjusting any covariables, the good quality embryos rate on day 3 of the 10 μl/ embryo group was 43% lower than that of the 30 μl/ embryo group (0. 57, 95% CI 0. 32, 1. 03), and there was no statistical difference (P>0. 05). In the minimum-adjusted model 2 (adjusted the level of AMH and type of insemination), proportion of good quality embryos on day 3 in group of 10 μl/ embryo significantly decreased by 51% (0. 49, 95% CI 0. 27,0. 90, P < 0. 05) compared with that in group of 30 μl/ embryo. Conclusion In a 30 μl microdrop, compared with individual cul turing, group culturing with the density of 10 μl / embryo did not benefit the development of the cleavage embryos and 30 μl / embryo was the optimal embryo density.

ABSTRACT

In this study, virtual reality technology is applied to the teaching of ART due to its characteristic of real-time interaction, and a virtual operation platform of intracytoplasmic sperm injection (ICSI) is developed in the scene of ART, which can be used for the practice and training of ICSI during teaching. By this virtual system we can overcome some kinds of teaching limitations brought by scarce experimental materials and expensive equipment, and it is suitable for multi-center and multi-region popularization and application for other ART laboratories.

ABSTRACT

Migraine is a neurological disorder characterized by attacks of moderate or severe headache and various neurological symptoms. Acupuncture, as a commonly used non-pharmacological therapy, has the advantage of obvious therapeutic effect and few side effects in the prevention and treatment of migraine. But the underlying mechanism of acupuncture on migraine remains unclear. Recently, advances in neuroimaging technology have helped to objectively assess the effect of acupuncture on treating migraine and offered new opportunities to explore the central mechanism of acupuncture on treating migraine. In order to better understand the current status of neuroimaging studies on the therapeutic mechanism of acupuncture on migraine and shed light on future research, this review aims to overview the neuroimaging studies in recent 10 years from two aspects: (1) Central mechanism of acupuncture on treating acute migraine attack; (2) Central mechanism of acupuncture on preventing migraine attack.

ABSTRACT

OBJECTIVE@#To compare the efficacy of scalp acupuncture combined with lower-limb intelligent feedback training and lower-limb intelligent feedback training alone for lower-limb motor dysfunction after stroke.@*METHODS@#A total of 154 patients with lower-limb motor dysfunction after stroke were randomly divided into an observation group (76 cases, 6 cases dropped off) and a control group (78 cases, 8 cases dropped off). The patients in both groups were treated with conventional medication and exercise rehabilitation training. In addition, the patients in the observation group were treated with scalp acupuncture combined with lower-limb intelligent feedback training. The scalp acupuncture was given at upper 1/5 of the anterior oblique line of parietal temporal area and upper 1/5 of the posterior oblique line of parietal temporal area. The patients in the control group were treated with lower-limb intelligent feedback training alone. All the treatment was given once a day, 6 days a week, totaling for 8 weeks. The affected-side lower-limb Brunnstrom stage and modified Ashworth scale (MAS) grade, 6-minute walk test (6MWT), Berg balance scale (BBS) score and modified Barthel index (MBI) score were evaluated before and after treatment in the two groups. The plantar pressure was measured by gait function evaluation system.@*RESULTS@#Compared before treatment, the Brunnstrom stage in the two groups was improved after treatment (@*CONCLUSION@#The scalp acupuncture combined with lower-limb intelligent feedback training could reduce the muscle tension of lower limbs, promote the separation movement mode of lower limbs, improve the plantar pressure distribution, and improve the balance ability and walking ability in stroke patients, and the curative effect is better than lower-limb intelligent feedback training alone.
