BACKGROUND: The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results. OBJECTIVE: To identify factors and their impact on the treatment effect of acupuncture in different outcomes. METHODS: Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects. RESULTS: The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01). CONCLUSIONS High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

Transcatheter aortic valve replacement(TAVR)has become one of the effective methods for treating patients with aortic valve disease.With the continuous maturity of technology,innovation of instruments and increasing experience,the indications for TAVR has been expanded.Following international trends,the number of TAVR in China has steadily increased with each passing year.In 2023,the long-term follow-up results of TAVR in low-risk AS patients further confirm the long-term benefits of TAVR.The relevant research on TAVR for patients with aortic regurgitation and patients with bicuspid aortic stenosis provide evidence support for the expansion of TAVR indications.At the same time,the development of valve devices and new technological innovations are emerging in an endless stream,and the new concept of full life cycle management is increasingly being valued.Especially in China,the development of local devices is progressing rapidly,and multiple devices have entered the clinical research stage.The clinical manifestations and research results are worth pursuing.

Piperazines are a class of new psychoactive substances with hallucinogenic effects that af-fect the central nervous system by affecting the level of monoamine neurotransmitters.Abuse of pipera-zines will produce stimulating and hallucinogenic effects,accompanied by headache,dizziness,anxiety,insomnia,vomiting,chest pain,tachycardia,hypertension and other adverse reactions,and may even cause cardiovascular diseases and multiple organ failure and lead to death,seriously affecting human physical and mental health and public safety.The abuse of new psychoactive substance piperazines has attracted extensive attention from the international community.The study of its pharmacological toxi-cology and analytical methods has become a research hotspot in the field of forensic medicine.This paper reviews the in vivo processes,sample treatment and analytical methods of existing piperazines,in order to provide reference for forensic identification.

Professor ZHOU Peng has deeply discussed the pathological characteristics of psoriasis vulgaris,emphasizing that the disease is usually manifested deficiency interweaved with excess,leading to frequent recurrence and persistent refractory,which may lead to psychological and emotional problems of patients.This paper further expounds the effect of blood stasis on the pathogenesis,progression and prognosis of psoriasis,and puts forward a new method of combining Lingnan fire needling and filiform needling acupuncture technique to treat psoriasis vulgaris with blood stasis syndrome.Professor ZHOU Peng believes that the treatment principle of this disease is"regulating the mind first,rectifying blood as a base,syndrome differentiating and eliminating pathogenic factors",aiming at comprehensively considering the etiology and symptoms,in order to achieve more effective treatment results.Combined with the analysis of dermoscopic signs,it provides a possible improvement direction for the treatment of psoriasis vulgaris from a new perspective.

Here,5 important pathogens carried by ticks in Maanshan City,Anhui Province,China were identified.In to-tal,642 ticks were collected from 13 villages around Maanshan City and identified by morphological and mitochondrial COI genes.The 16S rRNA gene of Francisella tularensis,ssrA gene of Bartonella,16S rRNA,ompA and ompB genes of Rickett-sia,16S rRNA and gltA genes of Anaplasma,and groEL and rpoB genes of Coxiella were sequenced.Reference sequences were retrieved from a public database.Phylogenetic trees were constructed with MEG A1 1.0 software.In total,36 Rickettsiae isolates were detected in 640 Haemaphysalis longicornis ticks,which included 20 isolates of Rickettsia heilongjian-gensis,16 of Candidatus Rickettsia jingxinensis,2 of Ana-plasma bovis,and 186 of Coxiella-like endosymbiont.R.hei-longjiangensis HY2 detected in this study and Anhui B8 strain,Ca.R.jingxinensis QL3 and those from Shanxi Prov-ince and Jiangsu Province,A.bovis JX4 and those from Shanxi Province were clustered on the same branch.Overall,17 ticks had combined infections and none of the 5 bacteria were detected in two Amblyomma testudinarium ticks.This is the first report of Ca.R.jingxinensis detected in H.longicornis ticks from Anhui Province.It is recommended that the two types of Rickettsia that cause spotted fever and A.bovis should be reported to local health authorities to initiate appropriate prevention and control measures.

Objective To employ digital optimization design in the quest for the optimal placement position of the distal tibiofibular syndesmosis tunnel.Methods A total of 100 distal tibiofibular syndesmosis CT datasets,acquired from 95 patients with syndesmosis injuries the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University,were imported into the Mimics 19.0 software for the purpose of reconstructing models.Created virtual tunnels between the tibia and fibula and overlaid them on the reconstructed models as virtual models.Additionally,3D printing was used to create actual models.In this study,eight parameters were measured.These included the length of the bone tunnel,the distance from the center of the tibial tunnel to the anterior and posterior aspects of the tibia,the distance from the center of the fibular tunnel to the anterior and posterior aspects of the fibula,the distance from the tibial tunnel point to the medial malleolus,the distance from the fibular tunnel point to the lateral malleolus,and the angle between the bone tunnel and the horizontal plane.Results Eight parameters were compared between the virtual model and the actual model,and there was no significant difference in the all measurement results of the actual bone tunnel and the virtual bone tunnel(P＞0.05).The anatomical analysis revealed a statistically significant difference in gender(P＜0.05),while there was no significant statistical difference observed in the affected side(P＞0.05).Conclusion Digital optimization design can provide precise and reliable bone tunnels for elastic fixation of the tibiofibular syndesmosis injury,thereby providing good stability for the surgery and helping patients recover ankle joint function as soon as possible.

Objective:To fabricate the composite scaffolds for bone regeneration with silk fibroin (SF), bacterial cellulose nanofibers (BCNR) and hydroxyapatite (HAp) and evaluate their osteogenic activity.Methods:HAp particles, BCNR and bone morphogenetic protein-2 (BMP2) were added into SF aqueous solution in turn, poured into molds of different sizes after being mixed evenly and processed at -25 ℃ for 24 hours to obtain frozen molds, and the composite scaffolds were frozen-dried by freezing-drying machine. The composite scaffolds with different mass ratios of SF and BCNR were divided into groups A (2∶1), B (4∶1) and C (6∶1), and the inactive composite scaffolds without BMP2 fell into group D. The surface morphology and pore structure of the scaffolds were detected by scanning electron microscopy. The porosity of the scaffolds was measured by mercury intrusion porosimeter. The stress-strain curve was obtained by using the universal material testing machine to compress the scaffolds, with which their compressive strength and Young′s modulus were analyzed. Immortalized mouse embryonic fibroblasts (iMEF) were inoculated on the composite scaffolds of group A, B, C and D. At 4 and 8 days after cell inoculation, the proportion of alive and dead cells in each group was detected by cell survival/death staining; the cell counting kit-8 (CCK-8) was used to detect cell proliferation activity in each group; the positive staining cells were detected in each group by alkaline phosphatase (ALP) staining; the ALP activity was observed in each group with ALP activity detection. A total of 15 female SD rats were selected to establish osteogenesis models with ectopic muscle bag. The composite scaffolds implanted with different SF/BCNR mass ratios and the inactive composite scaffolds without BMP2 fell into group A′ (2∶1), B′ (4∶1), C′ (6∶1) and D′ respectively, and a sham operation group was set at the same time, with 3 rats in each groups. In the sham operation group, the muscle bag and skin were sutured without scaffold implantation after the incision of skin, the blunt separation of the quadriceps muscle, and the formation of muscle bag in the muscle. In the other four groups, the corresponding scaffolds were implanted in the muscle bag and the muscle bag and skin were sutured. X-ray examination was performed at 2 and 4 weeks after operation to observe the osteogenesis in each group. At 4 weeks after operation, the implanted scaffolds and tissue complexes were collected by pathological tissue sectioning, HE staining and Masson staining, and for observing the osteogenesis by in each group. Immunohistochemical staining was also performed on the tissue sections to observe the expression of osteogenic markers type I collagen (COL1) and osteopontin (OPN) in each group.Results:Scanning electron microscopy showed that the lamellar and micropore structures of group B were more regular and uniform than those of groups A and C. The porosity rate analysis showed that the porosity rates of groups B and C were (89.752±1.866)% and (84.257±1.013)% respectively, higher than that of group A [(81.171±1.268)%] ( P<0.05 or 0.01), with the porosity rate of group C lower than that of group B ( P<0.01). The mechanical property test showed that the compressive strengths of groups B and C were (0.373±0.009)MPa and (0.403±0.017)MPa respectively, higher than that of group A [(0.044±0.003)MPa] ( P<0.01), and the Young′s moduli of groups B and C were (7.413±0.094)MPa and (9.515±0.615)MPa respectively, higher than that of group A [(1.881±0.036)MPa] ( P<0.01), with the compressive strength and Young′s modulus of group C higher than those of group B ( P<0.05 or 0.01). The cell survival/death staining showed that the number of dead cells of group B was significantly smaller than that of groups A, C and D at 4 days after cell inoculation, and that group B had the most living cells and the fewest dead cells at 8 days after cell inoculation. The results of CCK-8 experiment showed that at 4 days after cell inoculation, the cell proliferation activity of groups A and B was 0.474±0.009 and 0.545±0.018 respectively, higher than 0.394±0.016 of group D ( P<0.01); the cell proliferation activity of group C was 0.419±0.005, with no significant difference from that of group D ( P>0.05), while the cell proliferation activity of groups A and C were both lower than that of group B ( P<0.01). At 8 days after cell inoculation, the cell proliferation activity of group B was 1.290±0.021, higher than 1.047±0.011 of group D ( P<0.01); the cell proliferation activity of group C was 0.794±0.032, lower than that of group D ( P<0.01); the cell proliferation activity of group A was 1.086±0.020, with no significant difference from that of group D ( P>0.05); the cell proliferation activity of groups A and C was lower than that of group B ( P<0.01). At 4 and 8 days after cell inoculation, ALP staining showed that more positive cells were found in groups A, B and C when compared with group D, and more positive cells were found in group B than in groups A and C. At 4 days after cell inoculation, the ALP activity detection showed that the ALP activity of groups A, B and C was 1.399±0.071, 1.934±0.011 and 1.565±0.034 respectively, higher than 0.082±0.003 of group D ( P<0.01), while the ALP activity of groups A and C was lower than that of group B ( P<0.01). At 8 days after cell inoculation, the cell activity of groups A, B and C was 2.602±0.055, 3.216±0.092 and 2.145±0.170 respectively, higher than 0.101±0.001 of group D ( P<0.01), while the ALP activity of groups A and C was lower than that of group B ( P<0.01). X-ray examination results showed that at 2 weeks after operation, no obvious osteogenesis was observed in the sham operation group, group D′, A′ and C′, while it was observed in group B′. At 4 weeks after operation, obvious osteogenesis was observed in group A′, B′ and C′, with significantly more osteogenesis in group B′ than in the other two groups, while there was no obvious osteogenesis in the sham operation group and group D′. At 4 weeks after operation, the HE staining and Masson staining showed that a large number of uniformly distributed new bone tissue was formed in group B′, while only a small amount of new bone tissue was found locally in groups A′ and C′, and only part of new tissue was found to grow in group D′ with no obvious new bone tissue observed. The maturity of new bone tissue formed in group B′ was higher than that in group A′ and C′. Immunohistochemical staining showed more COL1 and OPN positive staining in group B′ when compared with groups A′ and C′. The expression intensity analysis of COL1 and OPN showed that in groups A′, B′ and C′, the expression intensity of COL1 was 2.822±0.384, 22.810±2.435 and 12.480±0.912 respectively and the expression intensity of OPN was 1.545±0.081, 5.374±0.121 and 2.246±0.116 respectively, with higher expression intensity of COL1 and OPN in groups B′ and C′ than that in group A′ ( P<0.01) and lower expression intensity of COL1 and OPN in group C′ than that in B′ group ( P<0.01). Conclusions:The composite scaffold for bone regeneration is successfully fabricated with SF, BCNR and HAp. The composite scaffold with a mass ratio of SF to BCNR of 4∶1 has uniform pore structure, high porosity, good mechanical properties and biocompatibility, excellent pro-osteogenic properties in vitro, as well as excellent osteo-inductivity and osteo-conductivity.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

OBJECTIVE: To observe the effect of Shugan Tiaoshen acupuncture (acupuncture for soothing the liver and regulating the mentality) combined with western medication on depression and sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, and investigate the potential mechanism from the perspective of cortical excitability. METHODS: Sixty patients with depression-insomnia comorbidity due to COVID-19 quarantine were randomly divided into an acupuncture group and a sham-acupuncture group, 30 cases in each one. The patients of both groups were treated with oral administration of sertraline hydrochloride tablets. In the acupuncture group, Shugan Tiaoshen acupuncture was supplemented. Body acupuncture was applied to Yintang (GV 24⁺), Baihui (GV 20), Hegu (LI 4), Zhaohai (KI 6), Qihai (CV 6), etc. The intradermal needling was used at Xin (CO₁₅), Gan (CO₁₂) and Shen (CO₁₀). In the sham-acupuncture group, the sham-acupuncture was given at the same points as the acupuncture group. The compensatory treatment was provided at the end of follow-up for the patients in the sham-acupuncture group. In both groups, the treatment was given once every two days, 3 times a week, for consecutive 8 weeks. The self-rating depression scale (SDS) and insomnia severity index (ISI) scores were compared between the two groups before and after treatment and 1 month after the end of treatment (follow-up) separately. The cortical excitability indexes (resting motor threshold [rMT], motor evoked potential amplitude [MEP-A], cortical resting period [CSP]) and the level of serum 5-hydroxytryptamine (5-HT) were measured before and after treatment in the two groups. RESULTS: After treatment and in follow-up, SDS and ISI scores were decreased in both groups compared with those before treatment (P<0.05), and the scores in the acupuncture group were lower than those in the sham-acupuncture group (P<0.05), and the decrease range in the acupuncture group after treatment was larger than that in the sham-acupuncture group (P<0.05). After treatment, rMT was reduced (P<0.05), while MEP-A and CSP were increased (P<0.05) in the acupuncture group compared with that before treatment. The levels of serum 5-HT in both groups were increased compared with those before treatment (P<0.05). The rMT in the acupuncture group was lower than that in the sham-acupuncture group, while MEP-A and CSP, as well as the level of serum 5-HT were higher in the acupuncture group in comparison with the sham-acupuncture group (P<0.05). CONCLUSION Shugan Tiaoshen acupuncture combined with western medication can relieve depression and improve sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, which is probably related to rectifying the imbalanced excitatory and inhibitory neuronal functions.
